The embodiment of the present application provides a cleaning machine 1000, and the cleaning machine 1000 may be a product used independently, or may be detachably cooperated with other structures, which is not limited herein.

Referring to fig. 5 and 6, the cleaning machine 1000 includes a dirt cup assembly 10 and a power assembly 20, wherein, referring to fig. 7, the dirt cup assembly 10 has a dust removal channel 10 a. Referring to fig. 9, 10 and 15, the power assembly 20 includes a mounting base, an ac motor 22, a dc motor 23, a dc power supply 24 and a utility power input interface 27, the mounting base is connected to the dust cup assembly 10, the dc power supply 24 is electrically connected to the dc motor 23, the dc power supply 24 provides a power source for the dc motor 23, the utility power input interface 27 is electrically connected to the ac motor 22, and the utility power provides a power source for the ac motor 22; the ac motor 22 and the dc motor 23 alternatively provide a negative pressure environment for the dust removal passage 10 a.

The cleaning machine 1000 of the embodiment of the application can be selected according to actual use requirements, for example, when a large-area cleaning or carpet cleaning is required, the commercial power input interface 27 can be connected with commercial power, the alternating current motor 22 is used for providing dust collection negative pressure for the dust collection channel 10a, and the problem that the dust collector in the related art is insufficient in cruising ability due to the fact that only the direct current motor is used is solved. When a small range of cleaning is required, or cleaning is performed in some places without power sockets, the dc motor 23 can be used to provide negative dust suction pressure, so that the cleaning machine 1000 has better flexibility in use. Therefore, the handheld machine cleaning machine of this application embodiment can satisfy and have sufficient duration when cleaning on a large scale, can be in the occasion direct use that does not have the commercial power again. In addition, the direct current motor 23 is provided with the independent direct current power supply 24 to supply power, and the commercial power is not required to be converted into low voltage to supply power to the direct current motor through a transformer, so that the cleaning machine provided by the embodiment of the application is not required to be provided with related equipment such as a transformer, the weight of the whole machine is reduced, the cleaning machine is convenient to hold by a user, and the labor intensity of the user can be reduced.

It should be noted that the ac motor 22 and the dc motor 23 in the embodiment of the present application are both motors that are configured with impellers, and therefore, the directional movement of the air can be generated only when the motors are started.

In the embodiment of the present application, the commercial power refers to power frequency alternating current, and the alternating current is generally characterized by using voltage, current and frequency. The voltage of the utility power varies from region to region, and the range of the utility power is mostly from 100V (volt) to 380V.

Because the power of the ac motor 22 is generally higher than the power of the dc motor 23, when the ac motor 22 is used to provide negative pressure to the dust removing passage 10a, a better cleaning effect can be achieved, for example, the ac motor 22 can be selected to provide negative pressure to the dust removing passage 10a in carpet cleaning and other occasions.

To facilitate gripping by a user, in one embodiment, referring to FIG. 5, the cleaning machine 1000 includes a handle 42 fixedly coupled to the mounting base. The shape of the handle 42 is not limited as long as it can be easily held by a user.

In one embodiment, a first airflow channel and a second airflow channel are formed in the mounting seat, the ac motor 22 is disposed on the first airflow channel, that is, the airflow in the first airflow channel flows through the ac motor, and the dc motor 23 is disposed on the second airflow channel, that is, the airflow in the second airflow channel flows through the dc motor 23. The first air flow channel and the second air flow channel are alternatively communicated with the dust removing channel 10a, namely, when the alternating current motor 22 works, the first air flow channel is communicated with the dust removing channel 10a, the second air flow channel is in a closed state, the air flow generated by the alternating current motor 22 cannot pass through the direct current motor 23, so that the direct current motor 23 cannot be influenced, and the direct current motor 23 cannot form resistance to the air flow in the first air flow channel. When the dc motor 23 is in operation, the second airflow channel is communicated with the dust removal channel 10a, the first airflow channel is in a closed state, the airflow generated by the dc motor 23 does not pass through the ac motor 22, and thus the ac motor 22 is not affected, and the ac motor 22 does not form resistance to the airflow in the second airflow channel. Thus, the dc motor 23 and the ac motor 22 are independent of each other and do not interfere with each other.

The dirt cup assembly 10 has a dirt removing passage 10a for separating impurities from the sucked air, and the dirt cup assembly 10 can be separated from the impurities by using a prior art dirt separating means, for example, referring to fig. 7, a cyclone 14 is disposed in the dirt cup assembly 10, wherein the cyclone 14 can be a one-stage cyclone or a multi-stage cyclone.

In one embodiment, the mounting base is removably attached to the dirt cup assembly 10, i.e., the mounting base and the dirt cup assembly 10 can be completely separated, such as by a snap-fit connection. Specifically, when the dirt cup assembly 10 needs to be cleaned, please refer to fig. 6, the dirt cup assembly 10 can be disassembled, so as to facilitate the operations of cleaning the dirt cup assembly 10.

In one embodiment, referring to fig. 6 and 7 in combination, the dirt cup assembly 10 includes a dirt cup 12, a top cover 11, a bottom cover 13, and a cyclone 14, wherein the top cover 11 and the bottom cover 13 are disposed at opposite axial ends of the dirt cup 12, and the cyclone 14 is disposed in the dirt cup 12. An air inlet 10b is arranged on the side wall of the dust cup 12, an air outlet 10c is arranged on the top cover 11, the air flow containing impurities enters the dust removing channel 10a from the air inlet 10b, and the air flow after dust removal through the dust removing channel 10a is discharged out of the dust cup assembly 10 through the air outlet 10 c.

In one embodiment, one end of the bottom cover 13 is rotatably connected to the dust cup 12, and the other end of the bottom cover 13 is connected to the dust cup 12 in a snap-fit manner, so that when impurities in the dust cup assembly 10 need to be cleaned, the bottom cover 13 is opened, and the impurities can be cleaned conveniently.

In some embodiments, a screen 111, such as a sponge, may be provided downstream of the exhaust port 10c to further filter fine impurities entrained in the airflow.

In one embodiment, the mounting seat includes a bottom plate 212, a space between the top cover 11 and the bottom plate 212 forms a sealed space 10d, and two through holes 212a are disposed on the bottom plate 212, wherein one through hole 212a is an inlet of the first air flow channel, and the other through hole 212a is an inlet of the second air flow channel. That is, the first airflow channel and the second airflow channel are independently communicated with the sealed space 10d, and the airflow dedusted by the dust cup assembly 10 enters the sealed space 10d through the exhaust port 10c and then alternatively enters the first airflow channel or the second airflow channel from the corresponding through hole 212 a. In this way, the design of the first and second air flow passages can be simplified.

The manner of achieving the communication of the first air flow passage or the second air flow passage alternatively with the dust removing passage 10a is not limited. Illustratively, in one embodiment, referring to fig. 10, the power assembly 20 includes at least two check valves 25, one check valve 25 is disposed in a first air flow path upstream of the ac motor 22, and another check valve 25 is disposed in a second air flow path upstream of the dc motor 23, wherein the suction force generated by the ac motor 22 can unidirectionally open the check valve 25 in the first air flow path and close the check valve 25 in the second air flow path; the suction force generated by the dc motor 23 can unidirectionally open the check valve 25 located on the second air flow passage and close the check valve 25 located on the first air flow passage. That is, the first air flow passage or the second air flow passage is alternatively communicated with the dust removing passage 10a by the two check valves 25 without electric control, thereby avoiding that the corresponding air flow passage cannot be closed due to failure of the electric element.

The check valve 25 is a structure that can open in the forward direction and close in the reverse direction.

The specific structure of the check valve 25 is not limited, for example, in some embodiments, the check valve 25 includes a valve plate and an elastic member, and the valve plate is rotatably connected to the side of the bottom plate 212 facing away from the sealed space 10 d; after the valve plate is opened, the valve plate can be reset to a closed state of closing the through hole 212a under the action of the elastic member.

Taking the valve sheet at the upstream of the ac motor 22 as an example, when the ac motor 22 works, because the valve sheet is located at the upstream of the ac motor 22, the suction force generated by the ac motor 22 applies an acting force to the valve sheet in the direction toward the ac motor 22, the acting force forces the valve sheet to rotate in the direction toward the ac motor 22 to open the corresponding through hole 212a against the acting force of the elastic member, and the negative pressure environment in the sealed space 10d forms an acting force deviating from the direction of the dc motor 23 to the valve sheet located in the second air flow channel, so that the valve sheet in the second air flow channel closes the corresponding through hole 212 a.

The elastic member may be a torsion spring, a cylindrical spring, or a rubber band, etc., which is not limited herein.

In another embodiment, referring to fig. 10 and 14, the check valve 25 is a piston, the mounting seat includes two motor mounting housings 211 supported on the bottom plate 212, the ac motor 22 is disposed in one of the motor mounting housings 211, the dc motor 23 is disposed in the other motor mounting housing 211, referring to fig. 13, a mounting cavity 211a is formed at the bottom end of the motor mounting housing 211, a bottom of the mounting cavity 211a is opened to form a first inlet 211b, the first inlet 211b is communicated with the through hole 212a, and the piston reciprocates in the mounting cavity 211a to selectively open or close the first inlet 211 b.

In an embodiment, referring to fig. 11 and 13, the motor mounting housing 211 includes a cylinder portion 2111, a contracting portion 2112 and a ring rib 2113, the contracting portion 2112 is connected to a bottom end of the cylinder portion 2111, the ring rib 2113 surrounds an inner wall of the cylinder portion 2111 or an inner wall of the contracting portion 2112, the ring rib 2113 forms a second inlet 211c, an air inlet end of the ac motor 22 is sealingly covered around one of the second inlets 211c and supported on the corresponding ring rib 2113, an air inlet end of the dc motor 23 is sealingly covered around the other second inlet 211c and supported on the corresponding ring rib 2113, and the ring rib 2113 and the contracting portion 2112 together form a mounting cavity 211 a. The ring rib 2113 plays a limiting and stopping role for the check valve 25, the check valve 25 is limited at one side of the ring rib 2113 facing the installation cavity 211a, and the check valve 25 is prevented from being sucked into the corresponding alternating current motor 22 or direct current motor 23 in a negative pressure environment.

In the projection of the plane where the second inlet 211c is located, the outer diameter of the check valve 25 may be larger than the size of the second inlet 211 c. Illustratively, the second inlet 211c is a circular hole, the projection shape of the check valve 25 on the plane of the circular hole is circular, and the outer diameter of the check valve 25 is larger than the inner diameter of the second inlet 211c, so that the check valve 25 can be prevented from being separated from the mounting cavity 211 a. Of course, the second inlet 211c and the check valve 25 may have other shapes, and are not limited thereto.

The motor mounting housing 211 may be an integrally formed structure, or may be a separate structure and fixedly connected together.

When assembling, the check valve 25 is inserted from the top end of the cylindrical portion 2111, the check valve 25 is elastically deformed by being pressed while passing through the second inlet 211c, and after the check valve 25 passes through the second inlet 211c and enters the mounting chamber 211a, the check valve 25 is restored to be deformed, and thereafter, the check valve 25 is not deformed by being pressed even in a negative pressure environment, and therefore, the check valve 25 is reliably restrained in the mounting chamber 211 a.

It should be noted that the material of the check valve 25 needs to ensure a certain structural strength, so that the check valve 25 will not deform elastically under the suction force of the corresponding ac motor 22 or dc motor 23.

The specific structure of the check valve 25 is not limited, and in an exemplary embodiment, referring to fig. 12, the check valve 25 includes a piston body 251 and an overflow supporting frame 252. Referring to the check valve 25 on the right side of fig. 13, when the piston body 251 opens the first inlet 211b, the flow support frame 252 abuts against the ring rib 2113, and referring to the dotted line and the arrow in fig. 13, the airflow flows from the first inlet 211b to the second inlet 211c through the flow support frame 252. The overflowing supporting frame 252 can circulate air flow to prevent the piston body 251 from blocking the second inlet 211 c.

In order to facilitate the installation of the motor mounting housing 211, in an embodiment, referring to fig. 10, a boss 2121 surrounding the through hole 212a is formed on the bottom plate 212, and referring to fig. 13, the constricted portion 2112 is inserted into the boss 2121 and supported on the boss 2121.

In one embodiment, referring to fig. 8, the mounting base includes a cover 213, the cover 213 covers the edge of the bottom plate 212, the cover 213 and the bottom plate 212 form a mounting space, and the ac motor 22, the dc motor 23 and the motor mounting housing 211 are all accommodated in the mounting space.

In one embodiment, referring to fig. 6, the cleaning machine 1000 further includes a holder 41, one side of the power assembly 20 is fixedly connected to the holder 41, and one side of the dirt cup assembly 10 is detachably connected to the holder 41. The cleaning machine 1000 may also be used in combination with other structures via the holder 41. In one embodiment, the holder 41 is provided with an air inlet duct 411, and an air outlet 411a of the air inlet duct 411 is communicated with an air inlet 10b of the dirt cup assembly 10. When the cleaning machine 1000 is used independently, a suction nozzle may be connected to an end of the air inlet duct 411.

It should be noted that the power line required by the utility power input interface 27 may be used as an independent accessory, and specifically, when the power line is required to be used to access the utility power, one end of the power line is plugged into the utility power input interface 27, and the other end of the power line is plugged into the utility power socket. When the utility power is not needed, the power line is unplugged from the utility power input interface 27.

In some embodiments, the ac motor 22 and the dc motor 23 may be switched in an automatic manner. For example, referring to fig. 15, the cleaning machine 1000 includes a control chip 35, a first circuit 31, a second circuit 32, a first electrical switch 36 disposed on the first circuit 31, a second electrical switch 37 disposed on the second circuit 32, and a detection circuit 33 for detecting whether the utility power is connected to the utility power input interface 27, the first circuit 31 is connected to the utility power input interface 27 and the ac motor 22, the second circuit 32 is connected to the dc power supply 24 and the dc motor 23, and the control chip 35 controls the first electrical switch 36 or the second electrical switch 37 to be turned on alternatively according to a detection result of the detection circuit 33 and a preset rule.

In an embodiment, the preset rule includes: when the mains electricity is not accessed, the second electrical switch 37 is kept closed, and the first electrical switch 36 is opened; when mains electricity is switched in, the first electrical switch 36 is closed, while the second electrical switch 37 is opened. That is, the default state of the cleaning machine 1000 is that the second electrical switch 37 is closed and the first electrical switch 36 is open.

It is understood that the cleaning machine 1000 includes a switch key 38, a first operation switch 381 disposed on the first circuit 31, and a second operation switch 382 disposed on the second circuit 32, the switch key 38 controlling the first operation switch 381 and the second operation switch 382 to be simultaneously closed or simultaneously opened.

Specifically, when the user presses the switch key 38, the first operation switch 381 and the second operation switch 382 are simultaneously closed, and since the first electrical switch 36 is opened by default and the second electrical switch 37 is closed by default, the second circuit 32 is in a conducting state and the first circuit 31 is in an open state, so that the dc motor 23 can enter an operating state. If the commercial power input interface 27 has no commercial power access, the direct current motor 23 is kept working all the time; if the mains supply input interface 27 is detected to have the mains supply connected, the control chip 35 controls the first electrical switch 36 to be closed and controls the second electrical switch 37 to be opened, at this time, the first circuit 31 is turned on, the second circuit 32 is turned off, and the cleaning machine 1000 is switched to the state of the alternating current motor 22.

It will be appreciated that in order to prevent accidental contact with the microswitch, the microswitch is located as narrow as possible and not easily accessible to the user or other objects.

In an embodiment, the detection circuit 33 is electrically connected to the commercial power input interface 27 to detect a voltage of the commercial power input interface 27, and when the voltage is greater than or equal to a preset value, the control chip 35 determines that the commercial power is connected to the commercial power input interface 27, and controls the first electrical switch 36 to be closed and the second electrical switch 37 to be opened. In one embodiment, the predetermined value is 100V to 220V.

It should be noted that the dc power supply 24 may be a dry battery, i.e. a disposable battery, which needs to be discarded after the power is used up, and then replaced with a new battery. The dc power supply 24 may also be a rechargeable battery, and the rechargeable battery may be recharged at a proper time.

For example, in an embodiment, referring to fig. 15, the cleaning machine 1000 includes a charging circuit 34, the charging circuit 34 is connected to the commercial power input interface 27 and the dc power supply 24, and the commercial power can charge the dc power supply 24 through the charging circuit 34.

It is understood that the charging circuit 34 may be unconditionally charging the dc power supply 24, that is, as long as the commercial power input interface 27 is connected to the commercial power, the charging circuit 34 charges the dc power supply 24 by itself without user selection.

The charging circuit 34 may also be operated by a user to charge the dc power supply 24. Illustratively, a charging switch is provided on the mounting base, and the charging switch is connected in series to the charging circuit 34. When the mains input interface 27 is connected to mains, the charging circuit 34 does not charge the dc power supply 24 if the user does not trigger the charging switch. When the user triggers the charging switch, the charging switch is closed, the charging circuit 34 is turned on, and the charging circuit 34 can charge the dc power supply 24.

Referring to fig. 16, an embodiment of the present invention further provides a control method of the cleaning machine 1000, including the following steps:

s1: and receiving a user operation instruction. For example, a user touches an operation switch provided on the mount, and the operation switch responds to a touch event of the user and triggers generation of an operation instruction.

S2: and judging whether the commercial power is accessed.

S3: and controlling the alternating current motor 22 or the direct current motor 23 to be electrified alternatively according to the judgment result and the preset rule.

Wherein, the preset rule comprises:

when the commercial power is not accessed, the direct current motor 23 is kept electrified;

when the mains supply is connected, the alternating current motor 22 is controlled to be electrified, and the direct current motor 23 is controlled to be powered off.

The sequence of the step S1 and the step S2 is not limited, and may be that the step S1 precedes the step S2.

The judgment result indicates whether the commercial power is accessed.

The control method of the embodiment of the application can automatically select the alternating current motor 22 or the direct current motor 23 to work according to the commercial power access condition. That is, the cleaner 1000 defaults to select the dc motor 23 to provide negative pressure for the dust removal channel 10a, and as long as the commercial power is connected, the operation is automatically switched to the ac motor 22 and the dc motor 23 is automatically turned off, so as to prevent the two motors from operating simultaneously.

The method for determining whether the mains supply is connected is not limited, for example, a micro switch is arranged at the mains supply input interface 27, and when a power plug is plugged into the mains supply input interface 27, the power plug triggers the micro switch, so that the fact that the mains supply is connected can be known. It will be appreciated that in order to prevent accidental contact with the microswitch, the microswitch is located as narrow as possible and not easily accessible to the user or other objects.

In one embodiment, step S2 includes:

detecting the voltage at the mains input interface 27;

comparing the voltage at the mains input interface 27 with a preset value;

when the voltage of the commercial power input interface 27 is not less than the preset value, it is determined that commercial power is connected, and when the voltage of the commercial power input interface 27 is less than the preset value, it is determined that no commercial power is connected.

Whether the commercial power is connected is judged according to the voltage at the commercial power input interface 27, so that the misjudgment can be avoided.

In one embodiment, the predetermined value is 100V to 220V.

Referring to fig. 1 to 4, the cleaning apparatus includes a vertical machine assembly 5000 and any one of the above cleaning machines 1000.

The vertical machine assembly 5000 includes a push rod 52 and a floor brush 51 disposed at a bottom end of the push rod 52, and referring to fig. 3, the vertical machine assembly 5000 has a dust suction passage 5a communicating with a dust suction port of the floor brush 51. The cleaner 1000 is detachably connected to the vertical machine assembly 5000, and when the cleaner 1000 is mounted to the vertical machine assembly 5000, the dust removal passage 10a communicates with the dust suction passage 5 a.

The cleaning device of the embodiment of the application has a first operation mode and a second operation mode.

In the first operation mode, the cleaning machine 1000 is separated from the vertical machine assembly 5000, and the cleaning machine 1000 performs the sweeping operation independently.

In a second mode of operation, cleaner 1000 is mounted on vertical assembly 5000, and cleaner 1000 and vertical assembly 5000 cooperate to perform a sweeping action. Specifically, the air entrains impurities such as dust and hair from the dust suction opening, enters the dust suction channel 5a, then enters the dust removal channel 10a of the dust cup assembly 10, is separated from the impurities in the dust removal channel 10a, then flows through the alternating current motor 22 or the direct current motor 23, and finally is discharged out of the cleaning device.

It should be noted that, in some embodiments, referring to fig. 3, the floor brush 51 is provided with a rolling brush 511 and a driving motor for driving the rolling brush 511 to rotate. Because the driving motor only needs to drive the rolling brush 511 to rotate, the driving motor can be a direct current motor with small power. Furthermore, the negative pressure in the dust suction passage 5a is provided by the ac motor 22 or the direct motor, so that it is not necessary to arrange a motor for forming the negative pressure in the floor brush 51, which makes the floor brush 51 compact and small, and facilitates the floor brush 51 to extend into a narrow space for cleaning, for example, the floor brush 51 can extend into the bottom of a sofa or a bed for cleaning.

In some embodiments, the cleaning apparatus includes a gas duct 53 connected between the end of the dust suction passage 5a of the floor brush 51 and the inlet of the dust removal passage 10a of the dirt cup assembly 10. The specific configuration of the air duct 53 is not limited as long as it can guide the airflow from the dust suction passage 5a to the dust removal passage 10 a.

In some embodiments, referring to fig. 1 and 2 in combination, when the cleaning machine 1000 is mounted on the vertical assembly 5000, the cleaning machine 1000 can slide up and down along the push rod 52 to adjust the distance between the cleaning machine 1000 and the floor brush 51, so as to extend the floor brush 51 a greater distance into the sweeping space, such as under a sofa. It will be appreciated that the air duct 53 is retractable in order to cooperate with the cleaner 1000 to slide along the push rod 52.

In one embodiment, the air duct 53 may be in the form of a bellows to achieve the telescoping. In another embodiment, the air duct 53 may be a multi-stage hard tube nested layer by layer, the hard tube may be a plastic tube or a metal tube, and the length of the air duct 53 is changed by telescoping between the multi-stage hard tubes.

The various embodiments/implementations provided herein may be combined with each other without contradiction.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
