Description

Air pressure distributor

The present invention relates to the technical field of air pressure regulation, and more particularly to a gas pressure distributor which is applied to the air supply of an air bed and has an adjustable air pressure distribution state.

The bed is an indispensable living furniture in human life, and with the advancement of the times and the rapid development of industrial technology, various uses and various beds have also appeared in people's lives. A plurality of air cushions support and fill the air cushions with air to support the human body, thereby producing an air air bed different from the comfort of the conventional spring bed.

Further, in the conventional air-bed technology, the air-cushion cylinder is inflated and filled with gas by directly inputting and storing air in a closed air-cushion cylinder; however, under the above technical structure, it is stored in the air cushion. The air inside the cylinder is often subjected to images of moisture and human body temperature, resulting in uneven pressure or moisture in the air cylinder, which affects the user's comfort when lying down.

Therefore, in response to the above-mentioned deficiencies, there has been a type of Low Air Loss air bed in the market, which is used to continuously pump air against a non-closed air cushion cylinder by means of a pneumatic pump. In order to generate air circulation in the air cushion cylinder, the air cushion cylinder is affected by moisture and body temperature; among them, it is worth mentioning that, in the above micro-leakage air bed technology, since the air cushion cylinder system is continuously In the state of air leakage, and the factor that the user's body weight is attached to the air cushion cylinder, so far, the technology of the micro-leakage air bed is using a large air pressure pump with large output efficiency. It can realize the pressure input of the air cushion cylinder.

Please refer to FIG. 1 , which is a schematic diagram of the use of a conventional micro-leakage air bed. As shown in the figure, in the conventional micro-leakage air bed technology, the air cushion is usually respectively connected by an inflating pump C and a connecting tube T. The air pressure input is performed by a plurality of independent air cylinders a of the bed A. Since the air cylinder a has a design of a pressure relief hole (not shown), the pneumatic pump C system continuously operates and supplies gas to maintain the air pressure of the air bed A. status.

On the other hand, when the human body P lies on the air bed, its support area is not only the area of the back B of the human body; as shown, obviously, when the human body P lies above the air bed A, The contact area of the air bed body often includes a portion of the head D and the back B of the human body and extends all the way to the rear heel H, and supports the overall weight of the human body P by the above parts.

It is worth noting that in the above lying process, the weight of the body supported by each body part is different. For example, the back B series supports the core part of the human body, and the supporting force provided by the body is different from the support only. The support force provided by the heel H after the weight of the human foot. However, in the prior art, no matter whether it is a technical structure of a general air bed or a micro air leaking air bed, the function of air pressure adjustment of the human body lying on each part of the air bed body cannot be further performed. Thus, when the gas pressures input to the respective air cushion cylinders are the same, the system tends to cause a certain part of the body to feel comfortable when the user lies on the side, but the other part feels that the air cushion cylinder is too hard or too soft. In this way, not only does the use comfort of the product be reduced, but even more, it is more likely to cause a gap between the user's body and the air bed body and cause secondary damage to the bone tendon.

Therefore, through the above description, we can know how to improve the existing air pressure pump and air bed, so that it can be used in the practical application to have the function of air pressure distribution according to the body area, so as to improve the lying comfort of the air bed. This is the primary focus of today's air bed pressure supply technology; in view of this, the creator of this case is trying to research and create, and finally developed a pressure distributor for this creation.

Moreover, the creation further provides a trigger switch, and when the pneumatic shunt module operates, the trigger switch can be activated and transmitted to the external control device, so that the external control device can accurately trigger the switch Master and adjust the time and frequency of rotation or stop of the air pressure diverting module with the drive module.

The rotation of the cover 112 can cause the second air pressure conversion chamber 116 to sequentially Connected to all, two or one of the air pressure output ports 114. In addition, the trigger switch 12 has a switching element 121 and a signal connecting member 122. The triggering portion 1121 of the cover 112 can be activated when the driving module 13 drives the rotation of the cover 112. The switching element 121, in turn, transmits a trigger signal to the external control device through the signal connector 122.

Please refer to FIG. 5 and FIG. 6 , and please refer to FIG. 7 a to FIG. 7 b , which is a perspective view of the trigger switch operation of the present invention. As shown in the figure, in the embodiment, the cover 112 is a circular cover. The triggering protrusions 1121 are formed on the edge of the circular cover body, and the main body 111 of the air pressure distribution module 11 is formed with a trigger switch riding protrusion 1111, and the trigger switch 12 is disposed on the trigger.
