Description
Technical Field
The invention relates to the technical field of intelligent furniture, in particular to a mattress with adjustable hardness and a cavity structure thereof.
Background
Mattresses are a common living article necessary for the masses of people, and most of the current mattresses are composed of a single mattress core or a mattress core and a decorative sleeve wrapped on the outer surface of the mattress core. Current mattress cores are generally referred to as palm pads and foam pads. The existing mattresses, whether they are palm mats or sponge mats, have the defect that the softness and hardness of the mattresses are difficult to keep lasting and stable along with the extension of the service time, and the deformed mattresses seriously affect the physical health of consumers.
On the other hand, because of the difference of personal ages, constitutions and living habits, each user has individual difference on the hardness requirement of the mattress, and the hardness degree of the mattress has direct relation on the resting and sleeping quality of the user and the growth and development of teenagers, so that the optimum hardness of the mattress of each user is said to be different. The palm cushion and the sponge cushion in the prior art can not adaptively adjust the hardness of the mattress according to the personalized requirements of the user, so that the use experience of the user is poor, and the optimal personalized resting environment is not beneficial to the user.
In order to solve the above problems, some mattresses have been developed in the prior art that can achieve hardness adjustment. For example, patent document CN107836906 discloses a soft and hard adjustable mattress, the mattress body of which comprises a knitted layer, a sponge layer, a soft and hard adjustable layer, a first steel wire mesh layer, a spring layer, a second steel wire mesh layer and a foam cushion layer. Wherein, the hardness of the mattress body is adjustable through the soft and hard adjustable layer, thereby improving the health and comfort of the mattress. Patent document CN107647957 discloses an air bag type pressure system and a medical binding device with the same, which can be applied to mattresses and the like, and comprises a soft and hard adjustable pressurizing device, a degassing and pressure releasing device, a pressure detector and a central processing unit. The central processing unit monitors the gas pressure in the flexible cavity through the pressure detector, and the gas pressure in the air is adjusted in real time through the soft and hard adjustable supercharging device and the exhaust pressure relief device, so that the overall hardness of the surface of the flexible object is adjusted, and a hardness-adjustable support body is formed. Patent document CN107174051 discloses a spring mattress capable of automatically adjusting the hardness, which is provided with a hardness adjustable layer, one side of the hardness adjustable layer is provided with a hardness adjustable port, the hardness adjustable port is connected with an electromagnetic valve and a hardness adjustable pump through a hardness adjustable pipe, an air pressure sensor is also arranged in the hardness adjustable layer, and an air pressure signal in the hardness adjustable layer is transmitted to a controller; the air pressure signal reflects the softness of the mattress; the controller is connected with the gear regulator, and the soft and hard regulation of the mattress is realized through gear number regulation; the hardness-adjustable layer is divided into a left hardness-adjustable bag and a right hardness-adjustable bag, and the hardness of the left part and the right part of the mattress can be respectively adjusted.
Therefore, the existing soft and hard adjustable mattress is characterized in that the soft and hard degree of the mattress is determined by changing the inflation quantity of the soft and hard adjustable layer inside the mattress and adjusting the air pressure. The hardness-adjustable mattress can change the internal air pressure according to the individual demands of users, so as to adjust the hardness of the mattress to a proper gear. And the hardness of the mattress with adjustable hardness is obviously better than that of the prior palm cushion or sponge cushion.
The firmness adjustable layer of a firmness adjustable mattress is typically comprised of a plurality of inflatable chambers, sometimes referred to as air bags. As shown in fig. 1, the inflatable chambers extend generally vertically relative to the direction of the human body during sleep, and the plurality of inflatable chambers are arranged side by side and abut each other to form a contact area between the mattress and the human body together, thereby providing mechanical support for the human body.
In the prior art, according to the gear set by the user, each inflatable chamber of the mattress is inflated until a preset uniform air pressure value is reached, so that the hardness of the area contacted with the human body is practically uniform. However, the body has its own physiological curve and accordingly, the softness requirements of the mattress are not consistent for each region of the body, e.g., the lumbar region requires greater firmness to provide adequate support, while the back contact region is desirably softer to provide a more comfortable feel to the user. Therefore, in the prior art, the inflatable chambers are completely consistent in hardness, so that the optimal supporting effect can not be brought to a user, and the sleeping and resting of a human body and the recovery of the human body are not facilitated.
There are also some mattresses of the prior art that are inflated separately for each inflation chamber to different air pressure values, so that the hardness of different parts of the human body contact area is different, for example, the inflation chamber near the waist is inflated to a higher air pressure value, and the inflation chamber near the back is inflated to a relatively lower air pressure value. However, this design brings new problems, firstly, the body heights of different users are different, for example, the user a shown by a solid line and the user B shown by a broken line in fig. 1 are compared, the contact area positions of the waist and the back of the user a and the user B can be found to have obvious deviation, and the inflatable mattress is manufactured according to the uniform specification design, so that the contact position of the waist and the back of each user is difficult to be matched with the position of one inflatable chamber in the mattress, the situation that the waist and the back of the user are positioned at the junction of the two inflatable chambers often occurs, and in this case, it is difficult to provide optimal support for the human body by adjusting the air pressure values of the inflatable chambers, especially if the air pressure values of the two adjacent inflatable chambers for supporting the waist and the back together are different, namely, the softness and hardness are different, and the user feels uncomfortable. On the other hand, the independent inflation and air pressure adjustment of each inflation chamber means that each inflation chamber is provided with a set of air inlet and outlet valves, inflation pipes, inflation connectors and other components, which clearly increases the cost and complexity of the mattress.

Detailed Description
Specific embodiments of the invention are described in further detail below with reference to the drawings and examples of the specification:
Referring to figure 2, a cavity structure for a mattress with adjustable softness is shown. The mattress with adjustable softness and hardness is composed of a plurality of inflatable chambers 1, the inflatable chambers 1 extend vertically relative to the direction of a human body during sleeping, the inflatable chambers 1 are distributed side by side and are adjacent to each other, a contact area between the mattress and the human body is formed together, and mechanical support is provided for the back, waist, buttocks and other parts of the human body. The inflation chambers 1 of the present invention can be inflated individually, so that by adjusting the inflation amount of each inflation chamber 1, each inflation chamber 1 reaches a predetermined air pressure value, which also determines the hardness of the contact area between the human body and the inflation chamber 1. For example, the inflatable chamber 1A which is expected to be in contact with the waist and the buttocks of the human body can be inflated to a larger air pressure value, so that the inflatable chamber reaches relatively higher hardness, and more powerful support is provided for the waist and the buttocks, thereby preventing lumbar deformation and relieving the symptoms of lumbar pain caused by strain; at the same time, the inflatable chamber 1B which is expected to be in contact with the back of the human body is inflated to a lower air pressure value, so that relatively lower hardness is generated, the inflatable chamber 1B which is expected to be in contact with the back of the human body is more comfortable, and the back muscle is facilitated to be relaxed, so that the human body is fully rested.
However, as described above, since the specifications, positions and sizes of the respective inflatable chambers 1 of the mattress are designed in a unified manner, and the heights and sizes of the human bodies of each user are different from each other, and the sleeping positions and positions of the individual habits are different, it is difficult to ensure that the contact areas of the back, waist or buttocks of each user with the mattress are exactly within the range of one inflatable chamber 1, and conversely, it is often the case that the contact areas of the back, waist or buttocks with the mattress are located at the adjacent positions of two adjacent inflatable chambers 1A, 1B. In this case, if the respective air pressure values of the two adjacent inflation chambers 1A, 1B are different, that is, the hardness is different, the user feels uncomfortable.
In view of this problem, the present invention provides for each inflatable chamber 1 comprising a mattress of adjustable firmness to have a transition zone 1C between at least two adjacent inflatable chambers (e.g. 1A, 1B), which transition zone 1C is said to be at the abutment of the adjacent two inflatable chambers 1A, 1B. Of course, a transition zone may also be provided between each two adjacent inflatable chambers of the mattress. With the inflation configuration of the transition zone 1C and by applying control during inflation (described in more detail below), the inflation pressure value of the transition zone 1C can be selected to be consistent with the pressure value of one of the two adjacent inflation chambers 1A, 1B, i.e., the stiffness of the transition zone 1C can be selected to be consistent with the stiffness of one of the inflation chambers 1A, 1B. Thus, when the contact area of the waist, the back, the buttocks and the like of the human body of the user is positioned at the abutting position of the two inflatable chambers 1A and 1B, at least one part of the contact area can be directly overlapped with the transition area 1C, for example, the part of the contact area of the waist and the mattress of the user A, which is shown by a solid line in fig. 2, is positioned in the range of the inflatable chamber 1B, and the other part of the contact area of the waist and the mattress is positioned in the transition area 1C at the abutting position of the inflatable chamber 1A and the inflatable chamber 1B, therefore, by controlling the inflation pressure value of the transition area 1C to be consistent with the inflatable chamber 1B, the hardness of the transition area 1C and the hardness of the inflatable chamber 1B are kept to be consistent, and the transition area 1C can be utilized to provide uniform hardness support for the whole contact area of the waist and the mattress of the human body. In contrast, if the mattress is used by a user B indicated by a broken line in fig. 2, a portion of the waist-to-mattress contact area of the user B is located within the range of the inflation chamber 1A, and another portion of the waist-to-mattress contact area is located within the transition zone 1C where both the inflation chamber 1A and the inflation chamber 1B adjoin, by controlling the inflation pressure value of the transition zone 1C to coincide with the inflation chamber 1A so that the softness of the transition zone 1C and the softness of the inflation chamber 1A remain uniform, the transition zone 1C can be utilized to provide a uniform hardness support for the entire contact area of the waist of the human body of the user B with the mattress. The same applies to the structure that uses the transition region to provide uniform stiffness support to other contact areas such as the back of the human body.
Fig. 3 shows a cross-section of the cavity of the transition zone 1C of the inflatable chamber of a firmness adjustable mattress and its inflatable structure. Referring to this figure, the transition zone 1C has a first side wall 201 common to the adjacent inflatable chambers 1A, a second side wall 202 common to the adjacent inflatable chambers 1B, and a top wall 203 flush with the top walls of the inflatable chambers 1A, 1B. Further, adjacent inflatable chambers 1A, 1B have a common adjacent chamber inner wall 301 therebetween, and the first and second side walls 201, 202 of the transition zone 1C extend inwardly and are integrally connected to the adjacent chamber inner wall 301, respectively. The first side wall 201, the second side wall 202 and the adjacent chamber inner wall 301 may all be made of the same airtight material, so that the chambers, i.e. the inflatable chambers 1A, 1B and the transition zone 1C, which are independent of each other and airtight to each other, are separated from the mattress interior by these side walls 201, 202 and inner wall 301, respectively. Of course, as another embodiment, as shown in fig. 4, the transition zone 1C includes a bottom wall 204 in addition to the first side wall 201, the second side wall 202 and the top wall 203, where the bottom wall 204 is integrally connected to the first side wall 201 and the second side wall 202, and the bottom wall 204 is integrally connected to the adjacent chamber inner wall 301.
A gas channel 205 is provided on each of the first and second side walls 201 and 202, and an electrically controlled opening and closing member 206 is mounted on the gas channel, and the electrically controlled opening and closing member 206 can be opened or closed under the excitation of an electrical signal, so that the gas channel 205 is conducted or closed. As shown in fig. 3 and 4, when the direction of air flow in the mattress is the arrow direction during inflation, and the electrically controlled opening and closing members 206 on the first side wall 201 and the second side wall 202 are both in an open state during the initial stage of inflation, air flows from the inflation chamber 1A into the chamber of the transition zone 1C through the air passage 205 on the first side wall 201, and then flows from the transition zone 1C into the inflation chamber 1B through the air passage 205 on the second side wall 202. Independent air pressure sensors are respectively arranged in the air inflation chambers 1A and 1B so as to detect the air inflation pressure value in the air inflation chamber. After the air pressure value of the inflatable chamber 1B is detected to reach the predetermined air pressure value, if it is desired that the air pressure value of the transitional area 1C is consistent with the inflatable chamber 1B, so that the transitional area 1C and the inflatable chamber 1B form a contact area with uniform hardness, the air channel 205 of the first side wall 201 can be closed by the electric control opening and closing component 206, and the air channel 205 of the second side wall 202 is kept conducting, so that the transitional area 1C is kept in communication with the inflatable chamber 1B, and the air pressure values in the transitional area 1C and the inflatable chamber are consistent; after the gas passage 205 of the first sidewall 201 is closed, the inflation chamber 1A is isolated from the transition zone 1C, so that the inflation chamber 1A may be continuously inflated or deflated independently until the inflation chamber 1A reaches a further predetermined pressure value, thereby providing a contact area for the inflation chamber 1A that is different from the hardness of the transition zone 1C and the inflation chamber 1B. Alternatively, if it is desired that the hardness of the transition area 1C is consistent with that of the inflatable chamber 1A according to the body height and shape requirements of the user, the electronically controlled opening and closing member 206 may be provided to close the gas passage 205 of the second sidewall 202 while the gas passage 205 of the first sidewall 201 is kept conductive after the gas pressure value of the inflatable chamber 1B is detected to reach a predetermined gas pressure value, so that the transition area 1C is kept in communication with the inflatable chamber 1A and isolated from the inflatable chamber 1B; the inflation or deflation adjustment of the inflation chamber 1A and the transition zone 1C may be continued until a predetermined air pressure value is reached, so that the inflation chamber 1A and the transition zone 1C together form a contact area of uniform hardness.
The structure of the electrically controlled opening and closing member 206 is shown in fig. 5A-5B, and the electrically actuated membrane based on the principle of ionic polymer and metal electrode composite (IPMC) is adopted as the electrically controlled opening and closing member 206 in the present invention. The electrically actuated membrane of ionic polymer and metal electrode composite (IPMC) is formed by plating a thin metal electrode on an ion exchange membrane, and the hydrated cations in the ion exchange membrane are rearranged under the electric field provided by the electrode, so that the electrically actuated membrane is subjected to bending deformation, and the electrically actuated membrane can recover its original shape after the electric field is removed. The electrically controlled opening and closing member 206 includes a first metal electrode layer 206A, an electrically actuated ionomer film 206B, a second metal electrode layer 206C, and an adhesive fixing portion 206D. The entire electric control opening and closing member 206 is fixed to the surface of the first side wall 201 (the second side wall 202) by the adhesive fixing portion 206D, and is aligned with the first side wall 201 (the second side wall 202) as the opening of the gas passage 205. Under no electric field excitation, the gas channel 205 is closed by an electrically actuated film layer formed by the first metal electrode layer 206A, the electrically actuated ionic polymer film 206B and the second metal electrode layer 206C, and under the condition that the electric field excitation is applied to the first metal electrode layer 206A and the second metal electrode layer 206C, as shown in fig. 5B, the electrically actuated ionic polymer film 206B drives the whole electrically actuated film layer to bend and deform, so that a gap between the electrically actuated film layer and the gas channel 205, namely, the gas channel 205 is opened, appears. By adopting the electrically actuated film as the electrically controlled opening and closing member 206, the volume is light, the space in the cavity is saved, the material is soft, the required driving voltage is low (1V), and therefore, the wires can be printed wires and integrated inside the side wall of each transition zone 1C. If the conventional air valve is installed on the side wall of the transition zone, after the user lies down, the air valve part is easy to form a relatively raised hard part due to deformation of the chamber, and discomfort is brought to human body contact. The power density of the electrically actuated film layer is 800W/g, so that the opening and closing actions of the gas channel 205 can be effectively ensured to be effectively implemented.
The hardness-adjustable air mattress of the present invention may be provided with a control unit to which the first metal electrode layer 206A, the second metal electrode layer 206C of each electronically controlled opening-closing member 206 are connected by flexible printed wires, and to which the air pressure sensors in each of the air inflation chambers 1A, 1B are also provided with flexible printed wires provided on the inner walls of the air inflation chambers 1A, 1B. The user can operate the control unit by using the buttons, and set the respective hardness of the back, waist, buttocks and other parts according to personal habits. The user may set whether the hardness of the transition region 1C is consistent with the inflation chamber 1A or the inflation chamber 1B according to the body height and the body shape of the user. The control unit determines the inflation pressure values of the inflation chambers 1A and 1B according to the hardness and softness gear set by a user, and determines whether the air pressure values in the inflation chambers 1A and 1B reach preset inflation pressure values according to real-time detection values provided by the air pressure sensors; when the predetermined inflation pressure value is reached, the control unit provides an excitation signal to the first metal electrode layer 206A and the second metal electrode layer 206C of the electrically controlled opening and closing member 206 to control the electrically controlled opening and closing member 206 to close the corresponding gas passage 205. The control unit may choose to close the gas channel 205 of the first side wall 201 or the second side wall 202, respectively, depending on whether the hardness of the transition zone 1C is consistent with the inflation chamber 1A or with the inflation chamber 1B.
Therefore, the invention provides a unique soft and hard adjustable mattress inflatable chamber structure, a transition area is arranged between at least two adjacent inflatable chambers, and the inflation pressure value of the transition area can be selected to be consistent with the pressure value of one of the two adjacent inflatable chambers, so that when the contact area of the waist, the back and the like of a user body is positioned at the adjacent position of the two inflatable chambers, the transition area can be used for providing uniform hardness support for the contact area of the body, and discomfort caused by different pressure values of the two chambers when the contact area of the waist, the back and the like of the user is exactly positioned at the adjacent position of the two inflatable chambers is avoided. In addition, the invention adopts a group of inflatable structures to realize independent inflation quantity adjustment and air pressure value control on each inflatable cavity, simplifies the structure of the mattress with adjustable hardness and reduces the cost of parts. The invention adopts the electric actuating film as the electric control opening and closing part of each transition zone, has light and thin volume, saves the space in the cavity, is soft in material, can be driven by a printed wire, does not generate any raised hard part when being contacted with a human body, and does not cause any discomfort to the human body.
