Description
Technical Field
The invention relates to an inflation and deflation valve seat, in particular to an inflation and deflation valve seat capable of adjusting inflation and deflation flow.
Background
The air valve is mainly used for inflating and deflating at least one air bag so as to provide an air cushion with proper hardness, such as an inflatable mattress, an inflatable sofa, an inflatable seat cushion and the like.
The general gas valve mainly utilizes an inflation valve to connect an air pump and an air bag, so as to lead in gas through the air pump and achieve the effect of inflating the air bag through the inflation valve, and prevent the gas entering the air bag from leaking through the inflation valve. When the air bag is to be deflated, an air-release valve is mainly connected to the air bag or the inflation valve, so that the air in the air bag can be deflated through the air-release valve.
For example, the chinese publication No. CN105443807 is a prior application filed by the applicant of the present application, and discloses a composite air distribution valve set, which comprises a control valve and at least two inflation/deflation valves capable of respectively inflating or deflating different air bag sets; the control air valve is provided with a normally closed first distribution flow passage communicated with one of the charge and discharge valves and a normally open second distribution flow passage communicated with the other charge and discharge valve; the two air inflation and release valves are respectively provided with a check valve, a normally open air inflation tube and a normally closed air release opening, so that when an air pump inflates air, one air bag group can be directly inflated, or the other air bag group is inflated by switching of the control air valve, and the air pressure in the air bag is maintained through the check valve when the air pump stops inflating air; when any one of the air-filling and air-releasing valves is actuated, the corresponding air bag can be released, thereby greatly simplifying the number of valve bodies and the control procedure.
For example, taiwan publication No. M521954 discloses a quick air-inflating device for an air cushion bed, which comprises a first air supply source and a second air supply source, wherein the first air supply source is connected to an air pipe, the second air supply source is connected to a quick-inflating pipe, the air pipe is connected to a first inflating part of the air cushion bed and has a connecting pipe connected to an air inlet pipe, and the quick-inflating pipe is connected to the air pipe and the air inlet pipe is connected to an inflating part of the air cushion bed. Therefore, through the assembly relation among the first gas transmission source, the second gas transmission source, the gas transmission pipe, the quick inflation pipe and the gas inlet pipe, after the first gas transmission source and the second gas transmission source provide gas, the first inflation part and the second inflation part can be quickly changed into an inflation state from an initial state, and when the first inflation part is in the inflation state, the first gas transmission source can be alternately communicated with a part of the gas transmission pipe, so that a part of the first inflation part is alternately changed between the non-inflation state and the inflation state.
However, the air valve sets are mainly used to charge and discharge at least one air bag by an air pump cooperating with at least one air valve, so that the charging and discharging flow cannot be changed according to the use requirement, resulting in the reduction of charging and discharging efficiency.

The second valve seat 202 is connected to the second air pump 402, the second valve seat 202 has two inflation valve sets 50, a second release valve 602 and a second air passage 212 connected to the second air pump 402, the two inflation valve sets 50 and the second release valve 602, the two inflation valve sets 50 include a third inflation valve set 503 and a fourth inflation valve set 504, the third inflation valve set 503 includes a third inflation valve 513 and a third air bag 523, the fourth inflation valve set 504 includes a fourth inflation valve 514 and a fourth air bag 524, the third inflation valve 513 and the fourth inflation valve 514 are respectively communicated with the second air passage 212, the third air bag 523 is connected to the third inflation valve 513, and the fourth air bag 524 is connected to the fourth inflation valve 514.
The communication valve 30 is used to connect the first valve seat 201 and the second valve seat 202, and is disposed between the first air passage 211 and the second air passage 212, so that the first air passage 211 and the second air passage 212 have a disconnected state and a connected state by the communication valve 30. In the embodiment, the communication valve 30 is installed in the second valve seat 202, but in practical applications, the communication valve 30 may be an independent valve seat connected between the first valve seat 201 and the second valve seat 202, or directly installed in the first valve seat 201.
Accordingly, as shown in fig. 4 and fig. 5, when the connection valve 30 is utilized between the first valve seat 201 and the second valve seat 202 to form the disconnected state between the first air passage 211 and the second air passage 212, since the first air passage 211 and the second air passage 212 are not connected to each other, and at this moment, the first air release valve 601 and the second air release valve 602 are both closed, the first air bag 521 and the second air bag 522 respectively introduce a gas through the first air pump 401, and the gas respectively passes through the first air passage 211 via the first inflation valve 511 and the second inflation valve 512 to form the inflated state with a small flow rate for the first air bag 521 and the second air bag 522. When the first air bag 521 and the second air bag 522 are about to deflate, the air enters the first air passage 211 from the first air bag 521 and the second air bag 522 through the first inflation valve 511 and the second inflation valve 512, and is discharged from the first air passage 211 through the first deflation valve 601 to form the air-release state with a small flow rate.

On the contrary, when the third air bag 523 and the fourth air bag 524 are to be deflated, the air flows from the third air bag 523 and the fourth air bag 524 into the second air passage 212 through the third inflation valve 513 and the fourth inflation valve 514, and then is discharged from the second air passage 212 through the second deflation valve 602 to form a small flow rate of the deflated state.
As shown in fig. 6 and 7, when the communication valve 30 is used to connect the first air passage 211 and the second air passage 212 between the first valve seat 201 and the second valve seat 202, the first air release valve 601 and the second air release valve 602 are now closed, the first air passage 211 and the second air passage 212 are connected to each other, so that the first air bag 521 and the second air bag 522 can simultaneously introduce the air by the first air pump 401 and the second air pump 402, at this moment, the third inflation valve 513 and the fourth inflation valve 514 are in a closed state, so that the gas passes through the first air passage 211 and the second air passage 212, then passes through the first inflation valve 511 and the second inflation valve 521 to simultaneously form the inflation states of higher flow rates for the first air bag 521 and the second air bag 522 respectively, this increases the inflation speed of the first airbag 521 and the second airbag 522.
Moreover, when the third air bag 523 and the fourth air bag 524 are to be inflated, at this moment, the first inflation valve 511 and the second inflation valve 512 are closed, and the third air bag 523 and the fourth air bag 524 can simultaneously introduce the gas through the first air pump 401 and the second air pump 402, and then the gas passes through the first air passage 211 and the second air passage 212, and then the third inflation valve 513 and the fourth inflation valve 514 to simultaneously form the inflated states of higher flow rates for the third air bag 523 and the fourth air bag 524, respectively.
When the first air bag 521 and the second air bag 522 are about to deflate, at this moment, the first deflation valve 601 and the second deflation valve 602 are both in an open state, the gas enters the first air passage 211 and the second air passage 212 through the first inflation valve 511 and the second inflation valve 512 from the first air bag 521 and the second air bag 522, and then is discharged outwards through the first deflation valve 601 and the second deflation valve 602 from the first air passage 211 and the second air passage 212 at the same time, so as to form the deflation state with a higher flow rate.
When the third air bag 523 and the fourth air bag 524 are to be deflated, the air enters the first air passage 211 and the second air passage 212 from the third air bag 523 and the fourth air bag 524 through the third inflation valve 513 and the fourth inflation valve 514, and is then discharged from the first air passage 211 and the second air passage 212 through the first deflation valve 601 and the second deflation valve 602 to form a high-flow deflation state.
