Specific embodiment

Substantive distinguishing features of the present utility model are made further with reference to specification drawings and specific embodiments It is bright.

A kind of air bed barometric control unit as shown in Figure 1, by housing 1, the controller 2 in the housing 1, The air-flow adjustment structure and appendix group 4 that air pump 3 and air pump 3 lead to are constituted, and air-flow adjustment structure is by the appendix group 4 lead to air bed 21（As shown in Figure 3）, the controller 2 is by air pressure ginseng in the inductive component monitoring appendix group 4 Number, and air pressure in air bed is adjusted by the air-flow adjustment structure.

When in use, realized by following steps：

1. by being input into the preset pressure parameter of each separate chamber to controller 2 so that each separate chamber has and is adapted to people Body couch support soft durometer layout；

2. the control of controller 2 air pump 3 is opened, and air pump 3 produces gases at high pressure, and gases at high pressure input air-flow regulation is tied In structure；

3. the gases at high pressure that air pump 3 is produced are branched in each separate chamber by air-flow adjustment structure；

4. controller 2 is by the gas pressure in each separate chamber of inductive component monitor in real time；

5. controller 2 is compared to preset pressure parameter with the real-time pneumatic parameter from inductive component, and controls gas Stream adjustment structure air pressure adjustment is carried out respectively to each separate chamber, it is ensured that in each separate chamber of air bed actual pressure parameter with it is pre- If pneumatic parameter is matched；

6. each separate chamber is sealed so that the gas pressure in each separate chamber remains constant.

Air bed inflation work is realized by above-mentioned steps.In use, inductive component constantly senses separate chamber Indoor gas pressure, and repeat above-mentioned side when certain bias occur in actual gas pressure parameter and pre-set gas pressure parameter Step 2- steps 6 in formula, ensure that air bed remains default holding state with this, it is ensured that the distribution of air bed support degree is begun It is consistent eventually.

In practical operation, when the gas pressure parameter in each separate chamber maintains constant value, air pump 3 is in and closes Closed state, and actual pressure parameter occur it is super it is default stir when controller 2 control under be again turned on, effective reducing energy consumption, Additionally, the peak of the air bed preset pressure parameter is because of the rated maximum pressure numerical value less than the air pump 3, it is ensured that air pump 3 can meet air bed is inflated to preset pressure parameter requirement.

In practical operation, the air-flow adjustment structure includes a valve body 5 and some groups of regulations on valve body 5 Component, the adjusting part includes control valve group and four cavities 6 being opened in valve body 5, opens up relatively close in the valve body 5 The air inlet supervisor 7 and exhaust supervisor 8 for closing（As shown in Figure 2）, the control valve group include intake valve 9 and air bleeding valve 10, described four First opening of cavity 6 is responsible for 7 by repeatedly kicking into the air intake branch of air valve 9 for a string and is led to the air inlet, the second opening with it is described Appendix group 4 is led to, and the 3rd opening is led to by a string of exhaust branch pipes of platoon air valve 10 with the exhaust supervisor 8, and the 4th opens Mouth leads to the inductive component.

Some groups of adjusting parts lead to air inlet supervisor 7 and exhaust supervisor 8, and it is simultaneously multiple separate chambers to realize air pump 3 Room supplies respectively, and coordinates exhaust supervisor 8 to realize that separate chamber gas pressure is adjustable.Due to four cavities 6 by the second opening with Separate chamber is led to, and centre does not have hermetic barrier part so that gas pressure and corresponding separate chamber gas in four cavities 6 Pressure is identical.When in use, controller 2 perceives gas pressure in four cavities 6 by induction pieces 20, and by control and regulation group Part completes gas replenishment process, and whole gas replenishment process includes aeration phase and regulation stage.
