In the air passage structure, the first control valve and the second control valve are switched between the first state and the second state, so that the air passage is switched between the air charging air passage and the air discharging air passage, and the first state and the second state refer to the two states that the first control valve and the second control valve are in an electrified state or an off-state. Specifically, through the switching of the first control valve and the second control valve in the two states of being simultaneously electrified or not electrified, the adjustment of the air passage structure is realized, and the air passage for air discharge are respectively formed, so that the air bag is inflated and deflated. Meanwhile, due to ingenious design of the air passage, related structures required for realizing air passage change in the traditional structure are greatly simplified, so that the overall arrangement structure of the air passage is more compact, and a structural basis is provided for further modularized structural design of the air passage. When in actual use, when the inflatable bag is required to be inflated, the first control valve and the second control valve can be selected to be not electrified, at the moment, external air flows to the air bag main channel sequentially through the inflation inlet, the second control valve, the air pump and the first control valve under the action of the air pump, and finally, the external air is conveyed to the corresponding air bag through the air bag air outlet nozzle communicated with the air bag main channel.

Because the pressure of the gas is obviously higher than the external atmospheric pressure when the gas is inflated and deflated, the quality of inflation and deflation can be ensured by good air tightness, and the user experience is better. Wherein, in order to make the whole arrangement of air flue more compact, it is preferable that the inflation inlet is arranged on the lateral wall of the first middle frame, and the deflation inlet is arranged on the lateral wall of the second middle frame.

Detailed Description

The utility model will be further described with reference to the drawings and examples.

As shown in fig. 1 to 13, the air pump 001 is a power source for the movement of air in the air passage. The air pump inlet pipeline 002 of the air pump 001 is communicated with the first connecting channel 201 of the second control valve 308, the air pump outlet pipeline 003 of the air pump 001 is communicated with the fourth connecting channel 204 of the first control valve 307, and two ends of the third connecting channel 203 are respectively communicated with the first control valve 307 and the second control valve 308. In actual placement, as shown in fig. 13, the structural portions of the airway may be designed as a stacked integrated airway. A first control valve 307 and a second control valve 308 are respectively arranged below the integrated air passage, and a first air bag electromagnetic valve 301, a second air bag electromagnetic valve 302, a third air bag electromagnetic valve 303, a fourth air bag electromagnetic valve 304 and a fifth air bag electromagnetic valve 305 for controlling the corresponding air bags are arranged. The integrated air passage mainly comprises three layers, the lowest layer is composed of an air passage fixed control valve or an electromagnetic fixed seat board, namely a first fixed seat board 004 and a second fixed seat board 006, and corresponding air passages are respectively arranged in the first fixed seat board 004 and the second fixed seat board 006. The middle layer is a second middle frame 007 and a first middle frame 005, and corresponding air passages are respectively arranged in the middle layer and are buckled with corresponding air passage parts of the second fixed seat board 006 and the first fixed seat board 004 respectively to form corresponding air passage outer wall surfaces. The topmost layer is an upper cover plate 008. The laminated arrangement can be quickly matched with a corresponding control valve during assembly, so that a subsequent integrated air passage structure can be formed, the assembly efficiency is greatly improved, and the whole structure is more compact.

The second control valve 308 includes a first connection passage 201, a second connection passage 202, and a third connection passage 203. The communication states of the internal air passages of the second control valve 308 are respectively: the first connection passage 201 communicates with the second connection passage 202, or the first connection passage 201 and the third connection passage 203, and the specific state is switched by adjusting the energization and the de-energization of the second control valve 308. The same first control valve 307 includes the fourth connecting passage 204, the fifth connecting passage 205, and the purge port 51. The communication states of the air passages inside the first control valve 307 are respectively: the fourth connection passage 204 communicates with the fifth connection passage 205, or the fourth connection passage 204 communicates with the air release port 51, and the specific state is switched by adjusting the energization and the de-energization of the first control valve 307.

The core for realizing the air passage switching is the air passage structural change caused by the adjustment of the valve core positions of the first control valve 307 and the second control valve 308. In both the inflated and deflated states, the gas pumping direction of the gas pump 001 is not changed, and the structure in the air passage and the flow direction of the gas are changed. The specific adjustment states are described as follows:

when inflation is required, as shown in fig. 1 to 8, the first control valve 307 and the second control valve 308 are not energized, the inflation port 41, the second connection channel 202, the first connection channel 201, the air pump inlet pipe 002, the air pump 001, the air pump outlet pipe 003, the fourth connection channel 204 and the fifth connection channel 205 and the air bag main channel 206 are sequentially communicated and form an inflation air passage, and after the air reaches the air bag main channel 206, the air is respectively conveyed into the air bag to be inflated according to control requirements through the control of the first air bag electromagnetic valve 301, the second air bag electromagnetic valve 302, the third air bag electromagnetic valve 303, the fourth air bag electromagnetic valve 304 and the fifth air bag electromagnetic valve 305 shown in fig. 7, so that the inflation requirement of the air bag is realized. As shown in fig. 3 to 6, when the first control valve 307 and the second control valve 308 are not energized, the valve element of the first control valve 307 blocks the air release port 51 and allows the fourth connection passage 204 and the fifth connection passage 205 to communicate. The spool of the second control valve 308 blocks the third connection passage 203, preventing the gas from flowing back to the first connection passage 201.

And when deflation is required, as shown in fig. 9 to 13, the first control valve 307 and the second control valve 308 are energized. At this time, the spool positions of the first control valve 307 and the second control valve 308 are changed by energization, and thus, also a change in the air passage is caused, in which the air bag main passage 206, the fifth connection passage 205, the third connection passage 203, the first connection passage 201, the air pump intake pipe 002, the air pump 001, the air pump outlet pipe 003, the fourth connection passage 204, and the air discharge port 51 are sequentially communicated and constitute an air discharge air passage. Thereby, the gas in the airbag is extracted by the gas pump 001 and discharged through the discharge port 51. As shown in fig. 9 to 10, when the first control valve 307 and the second control valve 308 are energized, spool positions of the first control valve 307 and the second control valve 308 are changed. At this time, the aforementioned relief port 51 is no longer blocked by the spool of the first control valve 307, the relief port 51 communicates with the fourth connecting passage 204, and the spool of the first control valve 307 isolates the fourth connecting passage 204 from the fifth connecting passage 205. The third connecting channel 203 is not blocked by the valve core of the second control valve 308, and the charging port 41 is blocked by the valve core of the second control valve 308. The original inflation channel is thereby transformed into the current deflation channel.
