Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
The disclosed embodiments provide a range hood 10, as shown in fig. 1, the range hood 10 includes a main machine 101, a smoking module 102, and a push rod structure 103.
Wherein the host 101 is used for generating suction.
The smoking module 102 comprises a smoke collecting cavity bottom shell 1021, a main smoke baffle 1022 and a connecting assembly 1023, wherein the smoke collecting cavity bottom shell 1021 is fixedly connected with the host 101, and the main smoke baffle 1022 is movably connected with the smoke collecting cavity bottom shell 1021 through the connecting assembly 1023.
The push rod structure 103 includes a fixed portion (not shown in fig. 1) fixedly connected with the host 101 and a movable portion 1032 fixedly connected with the main smoke barrier 1022.
The movable portion 1032 of the push rod structure 103 is configured to move according to the control of the fixed portion, and drive the main smoke baffle 1022 to rotate around the connecting component 1023, and when the main smoke baffle 1022 rotates to the target position from the position close to the smoke collecting cavity bottom shell 1021 through the driving of the movable portion 1032, the main smoke baffle 1022 and the smoke collecting cavity bottom shell 1021 form an air inlet of the smoke exhaust ventilator 10.
The movable portion 1032 is provided with a piezoelectric detection assembly (not shown in fig. 1) for detecting the pressure borne by the movable portion 1032; the movable portion 1032 is configured to drive the main smoke baffle 1022 to return to a position close to the smoke collection cavity bottom case 1021 from the target position according to control of the fixed portion when the pressure is greater than or equal to a preset threshold.
For example, the range hood 10 can be positioned directly above the cooking appliance, and the main smoke barrier 1022 is positioned in an initial position, i.e., a position near the smoke collection cavity bottom case 1021, when the user is not cooking, and the air inlet of the range hood 10 is closed. If the user starts cooking, the range hood 10 may instruct the main smoke baffle 1022 to rotate to the target position around the connection component 1023, and instruct the host 101 to start working, at this time, the main smoke baffle 1022 and the bottom casing 1021 of the smoke collecting cavity form an air inlet through which the smoke generated by the cooking of the user may be sucked.
If it is confirmed that the cooking is completed and the hood is to be closed, the user can press the main smoke baffle 1022 of the hood 10 with the back of his/her hand, elbow, or the like, where no or less stains are present. Because the main smoke barrier 1022 is fixedly coupled to the movable portion 1032 of the pushrod structure 103, the force applied by the user to the main smoke barrier 1022 can be transferred to the movable portion 1032, i.e., the total pressure experienced by the movable portion 1032 is the sum of the force applied by the user to the main smoke barrier 1022 and the gravity of the main smoke barrier 1022. The piezoelectric detection assembly can detect the pressure born by the movable portion 1032 of the push rod structure 103 in real time, when the pressure is greater than or equal to a preset threshold value, the movable portion 1032 can drive the main smoke baffle 1022 to return to a position close to the smoke collection cavity bottom shell 1021 from a target position according to the control of the fixed portion, and meanwhile, the smoke exhaust ventilator is closed, so that the operation of the smoke exhaust ventilator under the scene of not setting a button or a touch screen is realized.
Optionally, the target position is a position of the main smoke barrier 1022 when an angle between the main smoke barrier 1022 and the smoke collecting chamber bottom case 1021 is 40 ° or 45 °. In practical applications, the target position may be adjusted according to the size of the stove, which is not limited by the embodiments of the present disclosure.
For example, as shown in fig. 2, the fixed portion of the push rod structure 103 may be a push rod motor 103a, and the movable portion 1032 of the push rod structure 103 may be a push rod 103b and a link (not shown in fig. 2). As shown in fig. 3, the front end 1032a of the push rod 103b is connected to the push rod motor 103a (shown in fig. 2), the rear end 1032b is connected to the front end of the link, and the rear end of the link is connected to the main smoke barrier 1022 (shown in fig. 1). The push rod motor is fixed on the host 101 and is used for driving the push rod 103b to move when being opened, the push rod 103b drives the connecting rod to move, and the connecting rod drives the main smoke baffle 1022 to rotate by taking the connecting component 1023 as an axis.
Illustratively, when the range hood 10 is not open, the main smoke barrier 1022 is positioned adjacent to the smoke collection chamber bottom shell 1021. If the user starts cooking and starts the range hood 10, the range hood 10 controls the push rod structure to operate, i.e. the push rod motor 103a of the fixing portion starts to operate, and the push rod motor 103a can control the push rod 103b to perform stretching movement. The push rod 103b is fixed at a certain angle with the connecting rod, so that the connecting rod can push the main smoke baffle 1022 along with the extending movement of the push rod 103b, so that the main smoke baffle 1022 moves from a position close to the smoke collecting cavity bottom shell 1021 to the target position, and an air inlet is formed. If the user finishes cooking, the main smoke baffle 1022 can be pressed by the portion with no or less stains such as the back of the hand or the elbow of the arm, and the pressure born by the movable portion 1032 of the push rod structure is detected to be greater than or equal to the preset threshold value by the piezoelectric detection assembly, the range hood 10 can be closed, and at this time, the push rod motor 103a of the fixed portion starts to work, and the push rod motor 103a can control the push rod 103b to perform shrinkage movement. With the retracting movement of the push rod 103b, the link rod pulls the main smoke barrier 1022, so that the main smoke barrier 1022 returns from the target position to a position close to the smoke collecting chamber bottom case 1021.
Alternatively, the range hood 10 can be provided with a plurality of push rod arrangements.
For example, as shown in fig. 4, the piezoelectric detection component 1032c may be disposed between the front end 1032a and the rear end 1032b of the push rod 103b, or the piezoelectric detection component 1032c may also be disposed between the front end and the rear end of the link. Optionally, the piezoelectric detection component 1032a includes a piezoelectric material, and the piezoelectric detection component 1032a is configured to detect a voltage difference between a voltage of the piezoelectric material near the front end and a voltage near the rear end, and determine a pressure borne by the movable portion 1032 according to the voltage difference.
Since the piezoelectric material can generate voltage at two ends when being subjected to pressure, and the generated voltage is proportional to the received pressure, the piezoelectric detection component 1032c can determine the pressure received by the piezoelectric material by detecting the voltage at two ends of the piezoelectric material, and the pressure is the pressure received by the movable portion 1032 of the push rod structure 103. Specifically, the two ends of the piezoelectric material are the end of the piezoelectric material near the front end 1032a of the push rod 103b and the end near the rear end 1032b of the push rod 103b, respectively.
Specifically, when the main smoke baffle 1022 is at the initial position, that is, the position close to the bottom shell 1021 of the smoke collecting cavity, the movable part 1032 of the push rod structure 103 is not stressed, and the voltage at two ends of the piezoelectric material is 0; when the main smoke barrier 1022 is opened, that is, rotated to the target position, the movable portion 1032 of the push rod structure 103 bears the gravity of the main smoke barrier 1022, and the voltage across the piezoelectric material is V0; if the user presses the main smoke barrier 1022 (the pressing force may be small, for example, 5N (newton)), the movable portion 1032 of the push rod structure 103 bears the gravity of the main smoke barrier 1022 and the pressure applied by the user, and the voltage across the piezoelectric material is v0+Δv. If the piezoelectric detection component 1032c detects that the voltage v0+Δv is greater than or equal to the preset voltage threshold, it indicates that the pressure born by the movable portion 1032 of the push rod structure 103 is greater than or equal to the preset threshold, at this time, the range hood 10 may be closed, and at the same time, the movable portion 1032 of the push rod structure 103 may drive the main smoke baffle 1022 to return to a position close to the bottom shell 1021 of the smoke collecting cavity according to the control of the fixing portion.
Optionally, the range hood 10 is further provided with an electric control box, and control of each component can be achieved through the electric control box.
Optionally, the range hood 10 is further provided with a fan system, an air outlet pipe, and a first and a second lamp strip. Wherein, the fan system is installed inside the host 101 for generating suction force; the air outlet and the air outlet pipe are sequentially arranged at the outlet of the fan system; the first light strip is mounted at the bottom of the housing of the main unit 101, and may be disposed beside the speaker 20, for example; the second light strip is mounted on the side of the main smoke barrier 1022 that is adjacent to the smoke collection chamber bottom 1021.
Optionally, an oil screen of the range hood 10 is disposed at an air inlet of the fume collecting cavity bottom case 1021.
Optionally, the range hood 10 is further provided with two side smoke baffle plates, and the two side smoke baffle plates are used for closing two other open ends except for an air inlet opposite to the range in three open ends formed by the smoke collecting cavity bottom shell 1021 and the main smoke baffle plate 1022, so as to increase the negative pressure of the air inlet.
Alternatively, if the range hood 10 is powered on for standby, the main smoke barrier 1022 is in an off state, the first light band is turned on, and the second light band is turned off. When the user turns on the hood 10, the fan system starts to operate, and at the same time, the push rod motor 103a pushes the main smoke baffle 1022 to rotate to a target position, for example, to a position 45 ° with respect to the smoke collecting chamber bottom case 1021 through the push rod 103b and the link rod, and then the second light belt is turned on, at this time, the smoke can be discharged from the air inlet to the outside through the fan system. When the range hood 10 is turned off, the fan system and the second lamp band are turned off, and at this time, the push rod motor 103a pushes the main smoke barrier 1022 to return to the original position from the target position through the push rod 103b and the link, and finally the first lamp band is turned off.
In the technical solution provided in the embodiments of the present disclosure, if a user needs to close the range hood 10 during cooking, the main smoke baffle 1022 of the range hood 10 may be pressed by a portion of the back of the hand or the elbow where no stain exists. The piezoelectric detection component 1032a of the range hood 10 can detect the pressure caused by the gravity of the secondary pressing and the main smoke baffle 1022 to the movable part 1032 of the push rod structure 103, when the pressure is greater than or equal to a preset threshold value, the range hood 10 can be turned off and the main smoke baffle 1022 is controlled to return to a position close to the smoke collecting cavity bottom shell 1021 from a target position, so that the convenience of operation of a user is improved, meanwhile, the situation of control failure caused by controlling the range hood 10 through a button or a touch screen for a long time is avoided, the service life of the range hood 10 is prolonged, and the user experience is better.
In one embodiment, the range hood 10 further includes an infrared generator 104 and an infrared receiver 105.
Wherein the infrared generator 104 is adapted to emit an infrared measurement signal.
The infrared receiver 105 is configured to receive a reflected measurement signal of the infrared measurement signal reflected by an external object, so that the range hood 10 determines a distance from the external object according to the reflected measurement signal. The external object may be a user, a robot capable of cooking, or other objects, which is not limited by the embodiments of the present disclosure.
For example, as shown in fig. 5, the infrared generator 104 and the infrared receiver 105 may be disposed on a side of the main smoke barrier 1022 remote from the smoke collection chamber bottom case 1021. When the range hood 10 is in the closed state, i.e., the main smoke barrier 1022 is located near the smoke collection chamber bottom shell 1021, the infrared generator 104 and the infrared receiver 105 are in the on state, i.e., the infrared generator 104 continuously emits infrared measurement signals. If a user is currently in proximity, the user will reflect the infrared measurement signal to form a reflected measurement signal, which the infrared receiver 105 can receive.
Upon determining that the infrared receiver 105 receives the reflected measurement signal, the extractor hood 10 may determine that a user is currently in proximity, at which time the extractor hood 10 may determine a distance from the user based on the reflected measurement signal. If the distance is less than or equal to the preset distance threshold, indicating that the user may be currently required to cook, the range hood 10 may ask the user if cooking is required. Specifically, referring to fig. 5, the range hood 10 may further be provided with a speaker 20, and the speaker 20 is disposed at a connection area between the host 101 and the smoking module 102. Upon determining that the distance to the user is less than or equal to the preset distance threshold, the range hood 10 may play a first query, such as a voice of "please ask if cooking is required," through the speaker 20. After hearing the first query information, the user may send out confirmation information. Specifically, referring to fig. 5, the range hood 10 may further be provided with a microphone 30, and after the first query information is played through the speaker 20, the range hood 10 may instruct the microphone 30 to be turned on to receive a voice command from the user. I.e. the user may send out confirmation information by speech after hearing the first query information, e.g. the user may say "yes". After receiving the voice command, the range hood 10 may again query the user for the cooking mode, i.e., the range hood 10 may play a second query through the speaker 20, such as playing a voice "please confirm cooking mode". After hearing the second inquiry information, the user can send out confirmation information through voice, for example, the user can say "stir-fry mode". After receiving the voice command, the range hood 10 can be turned on to the quick-frying mode.
Specifically, the range hood 10 can provide three working modes, namely a small air volume mode, a normal cooking mode and a quick-frying mode, wherein the air volume provided by the main machine 101 in the three modes is 15m 3/min (cubic meter/min), 18m 3/min and 22m 3/min respectively.
In one embodiment, referring to FIG. 5, the range hood 10 further includes an infrared wide angle camera 106. The infrared wide-angle camera 106 is used for measuring an included angle between the upper end of an external object and the infrared wide-angle camera 106 and between the lower end of the external object and the infrared wide-angle camera 106, so that the range hood 10 can determine whether the external object meets a preset condition according to the included angle. The predetermined condition may be whether the height of the external object meets a predetermined height requirement or whether the external object is a predetermined type of user, such as adult, female or male, etc.
For example, upon determining that a user is currently approaching, the range hood 10 may instruct the infrared wide angle camera 106 to turn on. The infrared wide-angle camera 106 can measure the included angle between the connection line of the head of the user and the infrared wide-angle camera 106 and the connection line of the foot of the user and the infrared wide-angle camera 106, and the higher the height of the user is, the larger the included angle is. To avoid dangerous cooking behavior by children without adult supervision, it may be determined whether the user is an adult when it is determined that the user is in close proximity. Specifically, if the included angle α is less than or equal to arctan (H/L), the person approaching the range may be determined to be an adult, where L is the distance between the user and the range hood 10, and H is the height of a normal child, for example, the height H of the child is generally 1.2m (meters) to 1.5m, and the average value may be 1.4m.
If the user is determined to be an adult, the range hood 10 can ask the user if cooking is required. Specifically, the range hood 10 can play a first query message, such as a voice of "ask whether cooking is required", through the speaker 20. After hearing the first query information, the user may send out confirmation information. Specifically, after listening to the first inquiry information, the user can send out confirmation information by voice, for example, the user can say "yes". After receiving the voice command, the range hood 10 may again query the user for the cooking mode, i.e., the range hood 10 may play a second query through the speaker 20, such as playing a voice "please confirm cooking mode". After hearing the second inquiry information, the user can send out confirmation information through voice, for example, the user can say "stir-fry mode". After receiving the voice command, the range hood 10 can be turned on to the quick-frying mode.
The embodiment of the disclosure provides a smoke ventilator, can realize opening and closing of smoke ventilator under the scene that does not set up button or touch screen, has improved the convenience of user's operation, has also avoided simultaneously the control failure's that causes through button or touch screen control smoke ventilator 10 for a long time the condition, has improved smoke ventilator 10's life, and user experience is better.
Fig. 6a is a flowchart illustrating a range hood control method according to an exemplary embodiment, which is applied to the range hood according to any one of the above embodiments. As shown in fig. 6a, the range hood control method includes the following steps 601 and 602:
In step 601, the pressure exerted by the main smoke baffle of the range hood on the movable portion of the pushrod structure is obtained when the main smoke baffle is in the target position.
In step 602, if the pressure is greater than or equal to a preset threshold, the main smoke baffle is controlled to return from the target position to a position near the bottom shell of the smoke collection chamber of the smoke exhaust ventilator.
For example, the range hood may be disposed directly above the cooktop, and when the user is not cooking, the main smoke baffle of the range hood is in an initial position, i.e., a position near the bottom shell of the smoke collection cavity of the main smoke baffle, and at this time, the air inlet of the range hood is closed. If a user starts cooking, the smoke exhaust ventilator indicates the main smoke baffle to rotate to the target position, and at the moment, the main smoke baffle and the smoke collecting cavity bottom shell form an air inlet through which oil smoke generated by cooking of the user can be absorbed.
If the cooking is confirmed to be completed and the range hood needs to be closed, the user can press the main smoke baffle of the range hood by adopting the parts such as the back of the hand, the elbow and the like without stains or the parts with less stains. Because the main smoke baffle is fixedly connected with the movable part of the push rod structure of the smoke exhaust ventilator, the force applied by a user on the main smoke baffle can be transmitted to the movable part, namely the total pressure born by the movable part is the sum of the force applied by the user on the main smoke baffle and the gravity of the main smoke baffle. The range hood can detect the pressure born by the movable part of the push rod structure in real time when being opened, when the pressure is greater than or equal to a preset threshold value, the fixed part of the push rod structure is controlled to be opened, and at the moment, the movable part of the rod structure can drive the main smoke baffle plate to return to a position close to the bottom shell of the smoke collecting cavity from the target position according to the control of the fixed part.
Alternatively, if the user suddenly fails during cooking, the main unit of the range hood is stopped, but the main smoke baffle is still located at the target position, so that the user can press the main smoke baffle of the range hood to complete the storage of the main smoke baffle. Although the range hood is powered off, a small-volume power supply can be arranged in the range hood, and the power supply can provide electricity for the range hood after power is off so as to realize the storage of the main smoke baffle. The range hood can detect the pressure born by the movable part of the push rod structure under the condition that the power supply provides electric quantity, and when detecting that the pressure is greater than or equal to a preset threshold value, the fixed part of the push rod structure is controlled to be opened, and at the moment, the movable part of the rod structure can drive the main smoke baffle plate to return to a position close to the bottom shell of the smoke collecting cavity from the target position according to the control of the fixed part.
Optionally, when detecting that the pressure born by the movable part of the push rod structure is greater than or equal to a preset threshold, the range hood can control the fixed part of the push rod structure to be opened, at this time, the movable part of the rod structure can drive the main smoke baffle plate to return to a position close to the bottom shell of the smoke collecting cavity from the target position according to the control of the fixed part, and meanwhile, the range hood is controlled to be shut down, namely, the host of the range hood is controlled to stop working.
In one embodiment, as shown in FIG. 6b, the method includes steps 603 and 604:
in step 603, when it is determined that an external object is approaching, it is determined whether the external object satisfies a preset condition.
In step 604, when the external object meets a preset condition, the range hood is controlled to be opened, and the main smoke baffle is controlled to rotate from a position close to the bottom shell of the smoke collecting cavity of the range hood to the target position.
Alternatively, the external object may be a user, a robot capable of cooking, or other objects, which is not limited by the embodiments of the present disclosure. The preset condition may be whether the distance between the external object and the range hood meets a preset distance requirement, whether the height of the external object meets a preset height requirement, or whether the external object is a preset type of user, such as adult, female or male.
For example, the range hood may be provided with an infrared generator and an infrared receiver. When the smoke exhaust ventilator is in a closed state, namely the main smoke baffle is positioned at a position close to the bottom shell of the smoke collecting cavity, the infrared generator and the infrared receiver are in an open state, namely the infrared generator continuously emits infrared measurement signals. If the user approaches, the user reflects the infrared measurement signal to form a reflected measurement signal, and the infrared receiver can receive the reflected measurement signal.
When the infrared receiver is determined to receive the reflection measurement signal, the range hood can determine that a user is close at present, and at the moment, the range hood can determine the distance between the range hood and the user according to the reflection measurement signal. If the distance is less than or equal to the preset distance threshold, the user is indicated that the user may need to cook at present, at this time, the range hood may be opened, and the main smoke baffle is controlled to rotate from a position close to the bottom shell of the smoke collecting cavity of the range hood to the target position. If the distance is greater than the preset distance threshold, the user is not required to cook at present, and the range hood can keep the current state unchanged.
Or the range hood can be further provided with an infrared wide-angle camera. When it is determined that a user is approaching, the range hood can instruct the infrared wide-angle camera to be started. The infrared wide-angle camera can measure the included angle between the connecting line of the head of the user and the infrared wide-angle camera and the connecting line of the foot of the user and the infrared wide-angle camera, the higher the height of the user is, the larger the included angle is, and then the range hood can acquire the height of the user according to the distance between the range hood and the user and the included angle. If the height of the user is greater than or equal to the preset height threshold, the height of the user is enough to meet the requirements of cooking on the height, at the moment, the smoke exhaust ventilator can be started, and the main smoke baffle is controlled to rotate from the position close to the bottom shell of the smoke collecting cavity of the smoke exhaust ventilator to the target position. If the height of the user is smaller than the preset height threshold, the user is lower in height and insufficient for meeting the requirements of cooking on the height, and the range hood can keep the current state unchanged.
Or to avoid dangerous cooking behavior by children without adult supervision, it may be determined whether the user is an adult when it is determined that the user is in close proximity. Specifically, the range hood may be configured to determine that the person is a child if the included angle α is less than or equal to arctan (H/L), otherwise, the person is an adult, where L is a distance between the user and the range hood 10, and H is a height of a normal child, for example, the height H of the child is generally 1.2m (meters) to 1.5m, and an average value of 1.4m may be obtained. After the range hood obtains the included angle and the distance, L can be brought into the formula, i.e., whether the included angle a is less than or equal to arctan (H/L) is determined. If yes, the user is a child, and the range hood can be forbidden to be started for safety; if not, the user is an adult, at the moment, the smoke exhaust ventilator can be started, and the main smoke baffle plate is controlled to rotate from a position close to the smoke collecting cavity bottom shell of the smoke exhaust ventilator to the target position.
In one embodiment, as shown in FIG. 6c, the method includes step 605:
In step 605, when the external object does not meet the preset condition, alarm information is displayed, where the alarm information is used to warn that the external object that does not meet the preset condition may have dangerous usage behavior for the range hood.
For example, if the user does not meet the preset condition, it is indicated that the user may be dangerous during cooking, so that the range hood may display alarm information, for example, alarm music or alarm voice information may be played through a speaker set by the range hood. Specifically, if the height of the user is smaller than the preset height threshold value, the user is lower in height, the requirements of cooking on the height are not satisfied, and at the moment, in order to avoid the situation that the user privately uses the range hood under the condition that other members in the home are unknowing, the range hood can play alarm music or alarm voice information through a loudspeaker, and other members in the home are prompted to check.
Or if the user is a child, in order to avoid the child from using the range hood privately under the condition of no supervision of the adult, the range hood can play alarm music or alarm voice information and the like through a loudspeaker to prompt the adult to check or supervise.
In one embodiment, as shown in fig. 6d, step 604, that is, when the external object meets the preset condition, controls the range hood to be opened, and controls the main smoke baffle to rotate from the position close to the bottom shell of the smoke collecting cavity of the range hood to the target position, may be implemented through steps 6041 to 6043:
in step 6041, when the external object satisfies a preset condition, query information is displayed so that the external object determines a desired target cooking mode from a plurality of cooking modes provided by the range hood according to the query information.
In step 6042, confirmation information including the target cooking mode confirmed by the external object is acquired.
In step 6043, the range hood is controlled to open according to the target cooking mode, and the main smoke baffle is controlled to rotate from a position near the smoke collection cavity bottom shell of the range hood to the target position.
For example, if the range hood determines that the user currently approaching meets the preset condition, the user may be first queried as to whether cooking is required. Specifically, the range hood may play the first query information through the speaker, for example, play a voice of "ask whether cooking is required". After hearing the first query information, the user may send out confirmation information. Specifically, after the first query information is played through the speaker, the range hood may instruct the microphone set by the range hood to be turned on, and receive a voice command of the user. After hearing the first query, the user may send out a confirmation message by voice, for example, the user may say "yes". After receiving the voice command, the range hood can inquire the cooking mode of the user again, namely, the range hood can play second inquiry information through a loudspeaker, for example, play voice of 'please select a mode which is needed from a small air quantity mode, a normal cooking mode and a quick-frying mode'. After hearing the second inquiry information, the user can send out confirmation information through voice, for example, the user can say "stir-fry mode". After the smoke ventilator receives the voice command, the smoke ventilator can be started to be in a quick-frying mode, and the main smoke baffle plate is controlled to rotate to the target position from a position close to the bottom shell of the smoke collecting cavity of the smoke ventilator.
Specifically, the range hood 10 can provide three working modes, namely a small air volume mode, a normal cooking mode and a quick-frying mode, wherein the air volume provided by the main machine 101 in the three modes is 15m 3/min (cubic meter/min), 18m 3/min and 22m 3/min respectively.
The embodiment of the disclosure provides a smoke ventilator control method, which can realize the opening and closing of the smoke ventilator under the scene that the smoke ventilator is not provided with a button or a touch screen, improves the convenience of user operation, simultaneously avoids the control failure caused by controlling the smoke ventilator through the button or the touch screen for a long time, improves the service life of the smoke ventilator, and has better user experience.
