Description

Technical Field

[0001] The present invention relates to the technical field of air pressure regulation, and in particular to an air pressure distributor which is applied to the air pressure supply of an air mattress and has an adjustable air pressure distribution state. Background Art

[0002] As time progresses, people's demands for sleep quality have become increasingly important. Beds are an indispensable piece of furniture in human life, and a wide variety of beds with various uses and styles have appeared in people's lives. Among them, air mattresses have emerged, which utilize multiple air cushions filled with gas to support the body, thus providing a level of comfort that differs from traditional spring beds.

[0003] In the prior art, air is directly introduced and stored in a closed air cushion cylinder, causing it to expand and fill with gas. However, under this technology, the air stored within the air cushion cylinder is often affected by moisture and body temperature, resulting in uneven pressure or dampness in the air cushion cylinder, which in turn affects the user's comfort.

[0004] To address these shortcomings, a new class of minimally leaking air mattresses has emerged on the market. These utilize a pressure pump to continuously inflate the non-enclosed air cushion cylinder, creating air circulation within the cylinder and protecting it from moisture and body temperature. However, due to the constant leaking of the cylinder, coupled with the user's weight pressing against it, current minimally leaking air mattresses require large, high-efficiency pressure pumps to maintain sufficient air pressure.

[0005] See also Figure 1, which is a schematic diagram of the use of an existing micro-leakage air mattress. The micro-leakage air mattress inputs air pressure to multiple independent air cylinders a of the air mattress A through an air pump C and a connecting tube T. Since the air cylinder a is designed with a pressure relief hole (not shown), the air pump C operates continuously and provides gas to maintain the air pressure state of the air mattress A. When the human body P lies on the air mattress A, each air cylinder supports a part of the human body with a different weight. For example, the back B supports the core part of the human body, and the supporting force it provides is different from the supporting force provided by the heel H that only supports the weight of the sole of the human body. Whether it is a general air mattress or a micro-leakage air mattress, it is impossible to further adjust the air pressure for each part of the human body lying on the air mattress. In this way, when the gas pressure input into each air cylinder is the same, it often results in a situation where a user feels comfortable in one part of the body while lying on it, but another part feels that the air cushion cylinder is too hard or too soft. This not only reduces the comfort of the product, but can also easily cause a gap to form between the user's body and the air cushion body, causing damage to bones and tendons.

[0006] Therefore, through the above description, how to improve the existing air pressure pump and air mattress so that it can have the function of air pressure distribution according to body areas in practical application to improve the lying comfort of the air mattress? It is necessary to provide an air pressure distributor to solve the above-mentioned technical problems. Summary of the Invention

[0007] To achieve the aforementioned objectives, the present invention provides a gas pressure distributor comprising:

[0008] A gas pressure diversion device comprising:

[0009] a main body having a first air pressure conversion chamber, a deflated air communication chamber, and a plurality of air pressure communication chambers, wherein the first air pressure conversion chamber is connected to at least one air pressure input port, the deflated air communication chamber is connected to a deflated air recovery port, and the plurality of air pressure output ports are respectively connected to corresponding air pressure communication chambers and the deflated air recovery ports; and

[0010] a cover body, which is covered on the main body and has a second air pressure conversion chamber and a third air pressure conversion chamber recessed on a side surface facing the main body, wherein the second air pressure conversion chamber is in communication with the first air pressure conversion chamber; and

[0011] a driving device connected to the air pressure diversion device and driving the cover to rotate, so that the second air pressure conversion chamber is connected to at least one of the air pressure communication chambers through the rotation of the cover, and one of the air pressure communication chambers is connected to the air leakage communication chamber through the third air pressure conversion chamber, thereby generating pressure changes in the chambers;

[0012] When one of the air pressure communication chambers is connected to the air leakage communication chamber, the gas is discharged to the air leakage recovery port through the air pressure output port corresponding to the air pressure communication chamber;

[0013] The air pressure input port is connected to the air pressure sensor, and the main body further has an air leakage detection cavity, which is connected to at least one of the air pressure input ports. The cover body is provided with at least one pressure relief hole, and the air pressure sensor detects the air leakage pressure when the pressure relief hole is connected to the air leakage detection cavity.

[0014] Furthermore, the air pressure distributor also includes a trigger switch, which has a switch element and a signal connector. At least one protrusion protrudes from the outer peripheral wall of the cover. Through the rotation of the cover, the protrusion triggers the switch element and transmits the trigger signal to the external control device through the signal connector.

[0015] Furthermore, there are three protrusions.

[0016] Furthermore, the main body of the air pressure diversion device is formed with a trigger switch carrying protrusion, and the trigger switch is arranged on the trigger switch carrying protrusion.

[0017] Furthermore, the driving device includes a signal connection terminal, a plurality of positioning members, and a buffer spring. The signal connection terminal is used to connect to the external control device, and the buffer spring is arranged between the driving device and the air pressure diversion device.

[0018] Furthermore, there are two air pressure input ports and three air pressure output ports.

[0019] Furthermore, there are two air pressure input ports and four air pressure output ports.

[0020] Furthermore, the main body is formed with a through hole, and a driving shaft of the driving device passes through the through hole and is axially connected to a shaft connection hole of the cover.

[0021] Furthermore, a latch is passed through the driving shaft, and the latch is used to fix the air pressure diversion device and the driving device.

[0022] This invention achieves the effect of simultaneously delivering varying air pressures using a single air source, resulting in distinct air pressure saturations in different areas of the cushion. Compared to prior art technologies where each air pump delivers the same air pressure, this provides greater user comfort and has significant industrial applicability.

[0074] In order to further understand the features, technical means, and specific functions and purposes achieved by the present invention, more specific embodiments are listed here, followed by detailed descriptions with reference to the accompanying drawings and figure numbers as follows.

[0075] The following embodiments are described with reference to the accompanying drawings to illustrate various embodiments in which the present invention may be practiced. Directional terms used herein, such as "up," "down," "front," "back," "left," "right," "top," "bottom," "horizontal," and "vertical," refer only to the directions in the accompanying drawings. These directional terms are intended to illustrate and facilitate understanding of the present invention and are not intended to limit the present invention.

[0076] Please match Figures 2 to 5 , which are respectively a schematic diagram of the air pressure distributor according to the first embodiment of the present invention, an exploded schematic diagram of the air pressure distributor, schematic diagrams of the main body 11 at different viewing angles, and a schematic diagram of the cover 12 at one viewing angle. The air pressure distributor comprises an air pressure diversion device 1, a driving device 2, and a trigger switch 3.

[0077] Furthermore, the air pressure diversion device 1 is composed of a main body 11 and a cover 12 covering the main body 11. In the first embodiment, the main body 11 is recessed with a first air pressure conversion chamber 111, a deflated air communication chamber 112, and a second air pressure communication chamber 113. The first air pressure conversion chamber 111 is connected to the second air pressure input port 114, the deflated air communication chamber 112 is connected to a deflated air recovery port 115, and the deflated air recovery port 115 is located on a side away from the second air pressure input port 114. The three air pressure output ports 116 are respectively connected to the corresponding two air pressure communication chambers 113 and the deflated air recovery port 115 (i.e., the first air pressure output port 116a is connected to the first air pressure communication chamber 113a, the second air pressure output port 116b is connected to the second air pressure communication chamber 113b, and the third air pressure output port 116c is connected to the deflated air recovery port 115). Furthermore, the two air pressure input ports 114 are connected to an air supply device (not shown), which is used to transport gas through the two air pressure input ports 114 into the air pressure diversion device 1 (specifically, into the first air pressure conversion chamber 111). The main body 11 further has a gas leakage detection chamber 117, which is connected to the second air pressure input port 114b (in one embodiment, it can also be connected to the first air pressure input port 114a). The cover 12 is circular in shape and has a protrusion 124 protruding from its outer wall. A second air pressure conversion chamber 121 and a third air pressure conversion chamber 122 are recessed on a side of the cover 12 facing the main body 11. The second air pressure conversion chamber 121 is connected to the first air pressure conversion chamber 111. In the first embodiment, the air pressure input port is connected to an air pressure sensor S. The cover 12 is provided with two pressure relief holes 123. When the two pressure relief holes 123 are respectively connected to the air relief detection chamber 117, the air pressure sensor S can detect the air relief pressure and the pressure change of the weight in the pressure relief state. By recording and calculating the pressure drop time, the air pressure in the air cylinder is automatically set to provide feedback, allowing users of different weights to have a more comfortable experience lying on the air mattress. It should be noted that the three air pressure output ports 116 in this embodiment are connected to the air cylinder of the air mattress, so that gas can be transmitted to the air cylinder through the three air pressure output ports 116 to inflate the air cylinder. The air pressure sensor S can be located on the control device PCB board, but is not limited to this. The provision of the air pressure sensor S allows the control device to monitor the air pressure input status and the pressure value of the air pressure conversion chamber to adjust the air pressure pump.

[0078] Furthermore, the drive device 2 has a drive shaft 21. The main body 11 is formed with a through hole 118. The drive shaft 21 passes through the through hole 118 and is pivotally connected to a pivot hole 125 of the cover 12, thereby driving the cover 12 to rotate. Through the rotation of the cover 12, the second air pressure conversion chamber 121 is connected to at least one of the air pressure communication chambers 113, and one of the air pressure communication chambers 113 is connected to the air leakage communication chamber 112 through the third air pressure conversion chamber 122. The drive device 2 has a signal connection terminal 22, a plurality of positioning members 23, and a buffer spring 24. The signal connection terminal 22 is used to connect to an external control device (not shown). The buffer spring 24 is disposed between the drive device 2 and the air pressure diversion device 1 to buffer the impact caused by the operation of the drive device 2 and the air pressure diversion device 1, thereby preventing damage to both due to long-term impact. In addition, a latch 25 is passed through the driving shaft 21 . The latch 25 is used to fix the air pressure diverter device 1 and the driving device 2 , and prevent the driving shaft 21 from escaping from the through hole 118 .

[0079] Furthermore, the trigger switch 3 has a switch element 31 and a signal connector 32. When the cover 12 is rotated, the protrusion 124 of the cover 12 triggers the switch element 31, and a trigger signal is transmitted to the external control device through the signal connector 32. Furthermore, the main body 11 of the air pressure diversion device 1 is formed with a trigger switch-carrying protrusion 119, and the trigger switch 3 is disposed on the trigger switch-carrying protrusion 119. It should be noted that, through the arrangement of the trigger switch 3 and the protrusion 124 of the cover 12, when the protrusion 124 touches the trigger switch 3, the external control device can accurately determine the operating status of the air pressure diversion device 1, and thereby adjust the time and frequency of its rotation or stop through the driving module 2.

[0080] In the first embodiment, when the rotation angle of the cover body 12 is defined as 0 degrees (as shown in Figure 6A) or rotated clockwise by, for example, 180 degrees (as shown in Figure 6B), the second air pressure conversion chamber 121 connects all of the first air pressure connecting chambers 113a and all of the second air pressure connecting chambers 113b. At this time, the gas delivered by the air supply device passes through the air pressure input port 114, the first air pressure conversion chamber 111, the second air pressure conversion chamber 121, the two air pressure connecting chambers 113, and the two air pressure output ports 116 in sequence to the air cylinder of the air mattress for inflation.

[0081] Furthermore, when the cover body 12 rotates clockwise, for example, by 22.5 degrees (as shown in Figure 7A) or 202.5 degrees (as shown in Figure 7B), the second air pressure conversion chamber 121 is connected to part of the first air pressure connecting chamber 113a and part of the second air pressure connecting chamber 113b, and the air leakage detection chamber 117 is connected to one of the two pressure relief holes 123, the gas in the air cylinder will reduce the inflation volume and be deflated from the pressure relief hole 123, and the air pressure input port 114 connected to the air leakage detection chamber 117 can be connected to an air pressure sensor S, thereby detecting the deflation pressure while deflation, and determining the weight carried by the air mattress by recording and calculating the pressure change during the pressure relief state and the pressure drop time, and automatically feedback setting the internal gas pressure of the air cylinder after inflation through an external control device (not shown), so that users of different weights can lie comfortably on the air cushion massage bed.

[0082] Further, when the cover 12 rotates clockwise, for example, 67.5 degrees (as in Figure 8A ) or 247.5 degrees (as in Figure 8B ), the third air pressure conversion chamber 122 connects the first air pressure communication chamber 113a or the second air pressure communication chamber 113b with the air leakage communication chamber 112. At this time, the air pressure communication chamber 113 connected to the air leakage communication chamber 112 will be connected to the air leakage recovery port 115. Further, when the cover body 12 rotates 67.5 degrees clockwise to connect the first air pressure communication chamber 113a with the air leakage communication chamber 112, the gas in the gas cylinder connected to the first air pressure communication chamber 113a will flow into the third air pressure output port 116c through the air leakage recovery port 115, thereby allowing the leaked gas to be recycled and provided to the gas cylinder connected to the air leakage recovery port 115, allowing the gas supply device to reduce the pressure of its output efficiency and reduce the chance of damage. At this time, the second air pressure conversion chamber 121 connects to the second air pressure communication chamber 113b and inflates the gas to the gas cylinder connected to the second air pressure output port 116b. Furthermore, when the cover 12 rotates 247.5 degrees clockwise, causing the third air pressure conversion chamber 122 to connect the second air pressure communication chamber 113b with the air leakage communication chamber 112, the gas in the gas cylinder connected to the second air pressure communication chamber 113b will flow into the third air pressure output port 116c via the air leakage recovery port 115. This allows the leaked gas to be recovered and provided to the gas cylinder connected to the air leakage recovery port 115, thus also having the effect of reducing the pressure of the gas supply device output efficiency. At this time, the second air pressure conversion chamber 121 connects to the first air pressure communication chamber 113a, and the gas is inflated into the gas cylinder connected to the first air pressure output port 116a.

[0083] Furthermore, when the cover 12 is rotated clockwise, for example, by 135 degrees (e.g. Figure 9A) or 315 degrees (as shown in Figure 9B), the second air pressure conversion chamber 121 is connected to the first air pressure communication chamber 113a or the second air pressure communication chamber 113b, and the gas is inflated into the gas cylinder connected to the first air pressure output port 116a or the second air pressure output port 116b. Further, when the cover body 12 is rotated clockwise, for example, by 135 degrees, the second air pressure conversion chamber 121 is connected to the first air pressure communication chamber 113a, and the gas is inflated into the gas cylinder connected to the first air pressure output port 116a (at this time, the second air pressure output port 116b is in a locked state). Further, when the cover body 12 is rotated clockwise, for example, by 315 degrees, the second air pressure conversion chamber 121 is connected to the second air pressure communication chamber 113b, and the gas is inflated into the gas cylinder connected to the second air pressure output port 116b (at this time, the first air pressure output port 116a is in a locked state). It should be noted that the above-mentioned rotation may also be counterclockwise rotation, which is not limited here.

[0084] See also Figures 10 to 12 , which are respectively a schematic diagram of the air pressure distributor according to the second embodiment of the present invention, a schematic diagram of the air pressure distributor decomposition, and schematic diagrams of the main body 11 at different viewing angles. The difference between the second embodiment of the present invention and the first embodiment is that the main body 11 of the air pressure diversion device 1 has four air pressure output ports 116, which are respectively connected to the three corresponding air pressure communication chambers 113 and the leaked air recovery port 115. The leaked air recovery port 115 is located on a side away from the four air pressure output ports 116, and the cover 12 is provided with three pressure relief holes 123a and three protrusions 124a. Among them, when the three air pressure communication chambers 113 are connected to the second air pressure conversion chamber 121, and the air leakage detection chamber 117 is connected to one of the pressure relief holes 123a, the gas in the air cylinder will be discharged from the pressure relief hole 123a, and the air pressure sensor S will detect the air leakage pressure at the same time as the air is discharged to calculate the user's weight. Similarly, the air pressure inside the air cylinder after inflation can be automatically fed back and set through the external control device; and when the third air pressure conversion chamber 122 connects one of the air pressure communication chambers 113 with the air leakage communication chamber 112, the gas in the air cylinder corresponding to the air pressure communication chamber can be discharged to the air cylinder connected to the air leakage recovery port 115, thereby also reducing the pressure on the output efficiency caused by the continuous supply of gas by the air supply device. It should be noted that the relevant details and operating principles of the second embodiment can be referred to or explained in conjunction with the first embodiment. That is, those skilled in the art can understand the details and operating principles of the second embodiment after referring to the first embodiment, and will not be repeated here.

[0085] Through the above structure and the air pressure distributor provided by the present invention, the air mattress can achieve a massage effect through cyclic inflation and deflation. During deflation, the deflation pressure can be detected by the air pressure sensor S to calculate the user's weight. The air pressure inside the inflated cylinder is automatically set via an external control device, allowing users of different weights to comfortably lie on the air mattress. Furthermore, air is recovered through the deflation communication chamber 112 to the cylinder connected to the deflation recovery port 115, thereby reducing the pressure load generated by the continuous supply of air from the air supply device. Furthermore, the second embodiment provides more air pressure output ports, allowing the air mattress to have more controllable massage areas.

[0086] However, the present invention has been disclosed above using preferred embodiments, which are not intended to limit the present invention. Anyone skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the appended claims.

[0087] In summary, it should be clear to those skilled in the art that the present invention can indeed achieve the aforementioned objectives and complies with the provisions of the Patent Law, and therefore an application can be filed in accordance with the law.
