[0008] Furthermore, the first valve bodies may be configured into multiple groups, the switching frequency of at least one group of the first valve bodies being different from the switching frequency of the remaining first valve bodies, and the air components having different lifting frequencies are used to achieve massage modes with multiple lifting frequencies of the massage system.

[0009] Furthermore, the first valve bodies may be configured into a plurality of groups, each group of the first valve bodies having the same switching frequency, and the plurality of groups of the first valve bodies may be configured to cyclically ventilate the second valve bodies to extend the service life of the first valve bodies.

DETAILED DESCRIPTION

[0020] The following is combined with Figure 1-Figure 8 This application is described in further detail. Example 1

[0021] As mentioned in the background technology, in view of the problems in the prior art, the present application proposes a pneumatic pulse valve body assembly, the valve body assembly 6 is arranged between the gas source body 1 and the gas component 2 of the massage system, and specifically, the valve body assembly 6 includes: A first valve body 3 and a second valve body 4 which are jointly arranged and have different switching frequencies, wherein the switching frequency of the first valve body 3 is greater than the switching frequency of the second valve body 4; The first valve body 3 is provided with at least one, and the first valve body 3 includes a first air inlet end 31 and a first air outlet end 32, and the first air inlet end 31 is connected to the air source body 1; The second valve body 4 includes a second air inlet end 44, an air charging end 42 and an air release end 45, the air charging end 42 is communicated with the air-using component 2, and the second air inlet end 44 is communicated with the first air discharge end 32; The air-using component 2 is configured as an air bag 21 capable of achieving pneumatic adjustment of the seat; When the gas source body 1 inflates the airbag 21, the first valve body 3 performs a high-frequency and rapid switching action to control the state of the airflow entering the second valve body 4. After the airflow is controlled, it pulsatingly inflates the airbag 21 through the second valve body 4, so that the airbag 21 is continuously lifted up, thereby giving the occupant a "thump thump" pressing feeling, thereby giving the occupant a better massage experience.

[0022] In a preferred embodiment, the first valve body 3 is configured as an air source pulse generator with a fast switching function, and the air source pulse generator can pass the air flow into the second valve body 4 in a pulsating manner. The air source pulse generator can be selected as a quick-acting valve, a staggered switching valve or an air hammer, but is not limited to this. It should be noted that an ordinary solenoid valve can also be selected as one of the types of air source pulse generators.

[0023] In a preferred embodiment, the gas source body 1 can be configured as an air pump, and the first valve body 3 can be a pump-valve integrated structure integrated with the air pump. The advantage of such a configuration is that the structure is compact and occupies little space. In addition, a gas storage tank 8 for storing gas can be added between the gas source body 1 and the first valve body 3.

[0024] In a preferred embodiment, the first valve bodies 3 can be configured into multiple groups, each group of the first valve bodies 3 has the same switching frequency, and the multiple groups of the first valve bodies 3 can be configured to cyclically and alternately ventilate the second valve body 4, so that the working time of each group of the first valve bodies 3 per unit time can be shortened, thereby extending the service life of the first valve bodies 3.

[0025] In a preferred embodiment, the first valve bodies 3 can be configured into multiple groups, and the switching frequency of at least one group of the first valve bodies 3 is different from the switching frequency of the remaining first valve bodies 3, so that the air bag 21 can have different lifting frequencies, realizing massage methods with multiple pressing frequencies of the massage system. To further explain, if the occupant wants to experience a softer massage pressing sensation, the first valve body 3 with a more moderate switching frequency can be switched to indirectly inflate the air bag 21; if the occupant wants to experience a more rapid massage pressing sensation, the first valve body 3 with a faster switching frequency can be switched to indirectly inflate the air bag 21; and the switching method of the first valve bodies 3 with different frequencies can be manual and autonomous switching, or it can be set by a program to make each first valve body 3 cycle in a certain order to realize different modes of massage methods.

[0026] In a preferred embodiment, the second valve body 4 is configured as at least one memory alloy valve 41, the second air inlet end 44 of the memory alloy valve 41 is communicated with the first exhaust end 32 of the first valve body 3, the inflation end 42 of the memory alloy valve 41 is communicated with the air bag 21, when the gas source body 1 inflates the air bag 21 through the first valve body 3, the inflation passage of the memory alloy valve 41 corresponding to the air bag 21 is always in a conducting state; The memory alloy valve 41 has the characteristics of simple structure and low cost, and the memory alloy wire 43 also has good elasticity and damping properties, which can reduce vibration and noise. The specific structure of the memory alloy valve 41 is a conventional technical means in the field, and will not be described here. The following only further explains the process of the memory alloy valve 41 acting on the air bag 21: When the air bag 21 is inflated, the inflation passage of the memory alloy valve 41 is connected, and the deflation passage of the memory alloy valve 41 is closed; when the air bag 21 is pressurized, the inflation passage and the deflation passage of the memory alloy valve 41 are both in a closed state; when the air bag 21 is deflated, the inflation passage of the memory alloy valve 41 is closed, and the deflation passage of the memory alloy valve 41 is connected; this operation process is mainly suitable for seat lumbar supports due to the existence of a pressure-maintaining state. The specific selection of the memory alloy valve 41 can be a combination of a two-position three-way valve and a two-position two-way valve (also called a lumbar support valve), such as Figure 3 As shown; In conventional seat massage systems, such as waist and back massage or leg massage, it is usually only necessary to continuously inflate and deflate the airbag 21 to perform reciprocating pressure massage on the occupant's body. Therefore, the memory alloy valve 41 only needs to have an inflated state and a deflated state. The two-position two-way valve is the most preferred. Figure 1 and 2 shown. Example 2

[0027] On the basis of Example 1, further, the present application proposes a massage system, which is mainly applicable to car seats, including but not limited to waist massage, back massage or leg massage. The massage system includes an air component 2, an air source body 1, a control module 5 and the valve body assembly 6 described in the above embodiment, wherein: The gas-using component 2 is communicated with the valve body assembly 6 through an air path, and the gas-using component 2 is configured as an air bag 21 capable of realizing pneumatic adjustment of the seat, and the air bags 21 are arranged in multiple groups, and the arrangement positions and arrangement modes of the multiple groups of air bags 21 can be configured according to actual needs, wherein the arrangement modes of the multiple groups of air bags 21 include but are not limited to linear arrangement, S-shaped arrangement or annular arrangement, etc.; The gas source body 1 inflates the air bag 21 through the valve body assembly 6; The controller 5 is connected to the air bag 21 and the gas source body 1 respectively, and controls the gas source body 1 and the valve body assembly 6 to operate so as to inflate or deflate the air bag 21 .

[0028] In a preferred embodiment, the controller 5 can be controlled to operate the gas source body 1 and the valve body assembly 6 according to a specific timing to inflate or deflate the multiple air bags 21 in order. The specific timing should satisfy: the multiple air bags 21 can be lifted up in rotation; based on the above specific timing, when the multiple air bags 21 are arranged in a ring shape, the multiple air bags 21 lifted up in turn cooperate with the pulsating pressure frequency of the valve body assembly 6, so that the occupant can feel the pressure massage feeling of continuous sliding in a certain direction, thereby achieving the massage effect of seat kneading and vibration; To be further detailed, based on this specific timing, when the leading air bag 21 begins to deflate from a saturated state, the adjacent subsequent air bag 21 continues to be inflated; when the deflation of the leading air bag 21 reaches 20%, the subsequent subsequent air bag 21 continues to be inflated to reach saturation, and begins to deflate from a saturated state. In this way, the multiple air bags 21 are cyclically inflated and deflated, so that a kneading and vibrating massage method with a cyclic trailing effect is achieved between the multiple air bags 21.

[0029] In a preferred embodiment, the gas source body 1 can also be directly connected to an ordinary switch valve such as a solenoid valve 7 at the same time. The solenoid valve 7 can be a combination of a two-position three-way valve and a two-position two-way valve (mainly suitable for lumbar support), or a two-position two-way valve (mainly suitable for waist and back massage or leg massage), but is not limited to this. The controller 5 controls the gas source body 1 and the solenoid valve 7 to inflate or deflate the air bag 21 to achieve traditional pneumatic massage, that is: the pneumatic massage method achieved by the valve body assembly 6 in this embodiment can be used in the car seat massage system in combination with the traditional pneumatic massage method.
