Intake switching valve with pressure relief function

The present invention relates to the technical field of air pressure regulation, and more particularly to an air intake switching valve having a pressure relief function applied to an air bed and having a switchable air pressure 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 pump directly injects air into a plurality of air cushion cylinders, and the air cushion cylinders are inflated to support the user's body weight, thereby achieving Unlike the general spring bed for lying comfort. However, in the actual use of the above air-cushion bed products, it has been found that for patients with inconvenient movement and general paralysis, it is unable to provide the desired back massage and soothing effect, even though the air-cushion bed has been provided higher. Lying comfort, but when the patient with inconvenient movement or general paralysis lies on it, he often suffers from hemorrhoids and ulceration caused by poor blood circulation in his back.

Among them, with the continuous improvement of air-bed technology, in order to improve the poor blood circulation, hemorrhoids and ulceration caused by the above-mentioned patients with inconvenient movement or full body lying on the air bed, there is a kind of neighboring on the market. Between the air cushion cylinders, alternating air cushioning functions can be performed to achieve a wave-like massage effect. Please refer to FIG. 1 , which is a schematic diagram of an existing alternate air bed. As shown in FIG. 1 , the existing alternating air bed is mainly composed of an inflatable pump 2 and an air bed body 3 . The air bed body 3 has a plurality of odd air cushion cylinders 31 and a plurality of even air cushion cylinders 32 arranged in a staggered manner, and the odd air cushion cylinders 31 and the even number of air cushion cylinders 32 are respectively connected to a base air conduit. 21 and an even number of air ducts 22.

As described above, the base air duct 21 and the even air duct 22 are connected to the inflating pump 2, so that the inflating pump can inflate the odd air cushion cylinders 31 and the even number of air cushion cylinders 32, respectively. Acting, and making the air-cushion bed body 3 have a undulating effect of undulation; in addition, because the undulating effect of the bed body is capable of generating massage for the back of the user, when the user is full-body squatting In the case of a patient with limited mobility, the alternating air bed can effectively improve the comfort of lying and improve the acne or ulceration of the patient due to prolonged bed rest.

It is well known that when the human body lies on the bed, its supporting area is not only the area of the back of the human body; please continue to refer to Figure 1, and please also refer to Figure 2, which is a schematic diagram of the human body lying on the alternating air bed. As shown in FIG. 1 and FIG. 2, when the human body 4 lies on the above-mentioned alternate air cushion bed, it is obvious that the contact area between the human body 4 and the air cushion bed body 3 includes the rear head 41 and the back 42 of the human body and extends all the way. The portion of the heel 43 is rearward, and the overall weight of the user is supported by the body portion.

However, it is worth noting that, in the above, the weight of the body supported by each body part is different. For example, the back 42 supports the core part of the human body, and the support force provided by it is different from that of only the support. The support force provided by the heel 43 after the weight of the human foot; in the conventional alternate air bed technology, when the inflatable pump 2 is used for all the odd air cushion cylinders 31 of the air bed body 3 and all the even air cushion cylinders 32 simultaneously In the case of inflation and deflation, it is impossible to further perform the function of adjusting the air pressure for each part of the human body lying on the air mattress body.

Wherein, 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 lying on the user, but the other part feels that the air cushion cylinder is too hard or too soft. In this case, not only will the use comfort of the product be greatly reduced, but moreover, the user will be able to create a gap between the body and the air bed when lying down, and in the case of lying for a long time. Causes secondary damage to the body's bones or tendons.

Therefore, through the above description, we can know how to improve the existing alternate air bed technology, so that it can produce different air pressure input effects for different parts of a single air bed body, thereby further improving the comfort of lying. Degree is the primary focus of today's alternating air bed technology; in view of this, the creators of this case tried to research and create, and finally developed a kind of air intake switching valve with pressure relief function. After the air pump is installed on the air duct of the air bed, it can be realized by a user manually adjusting on a single air bed body, and the air cushion cylinders of different parts have different input gas pressure effects. .

The purpose of the present invention is to provide an air intake switching valve with a pressure relief function, which is mainly applied to the air pressure of an air bed and has a technology for switching the air pressure of a part of the air bed, wherein After the creation of the air pressure pump output conduit combined with the air bed technology, the air cushion cylinder of different parts can be realized on the air bed with different air pressure effects, so that the air bed can be placed according to the user's body when lying down. Each part corresponds to the position of the air bed, and is adjusted to the air pressure (hardness) of the corresponding part of the air bed, thereby greatly improving the comfort and product performance of the air bed.
