The diaphragm pump head includes valve plate 10, pump head lid 11, elastic diaphragm 12 and normally closed check valve 13, valve plate 10 is established on the diaphragm pump body 20 and sealed leather cup 2011, pump head lid 11 is located valve plate 10 top, pump head lid 11 is last to have inflation inlet H11a and disappointing mouth H11b. The inflation port H11a is used for inflating an external air-receiving device, such as a smart sports watch, an electronic sphygmomanometer, or the like. And the air leakage opening H11b is used for discharging air to the air receiving equipment, and the air in the air receiving equipment can flow back to the diaphragm air pump head and then is discharged from the air leakage opening H11b.

Elastic diaphragm 12 is sealed between valve plate 10 and pump head cover 11, and first air chamber H100 is defined between elastic diaphragm 12 and valve plate 10, and second air chamber H110 is defined between elastic diaphragm 12 and pump head cover 11. A normally closed check valve 13 is provided on the valve plate 10 to control one-way entry of gas in the diaphragm pump body 20 into the first gas chamber H100.

The elastic membrane 12 is provided with an opening and closing hole H12, when the air pressure in the first air chamber H100 increases, the elastic membrane 12 deforms upwards to open the opening and closing hole H12 and close the air release hole H11b, and when the air pressure in the second air chamber H110 increases, the elastic membrane 12 deforms downwards to close the opening and closing hole H12 and open the air release hole H11b. Preferably, the elastic membrane 12 can be made of elastic plastic material, such as silicone rubber, silicon rubber, fluorine rubber, nitrile rubber, neoprene rubber, etc.

That is, the normally closed check valve 13 on the valve plate 10 is kept in a normally closed state, and when the first air chamber H100 is not inflated, the elastic diaphragm 12 is kept in an original state, the opening and closing hole H12 is kept closed, the air release hole H11b is kept open, and there is no communication between the first air chamber H100 and the second air chamber H110. The elastic diaphragm 12 has elasticity, the elastic diaphragm 12 is isolated between the first air chamber H100 and the second air chamber H110, when the air pressure in the first air chamber H100 and the second air chamber H110 changes, the balance state of the elastic diaphragm 12 is broken, the elastic diaphragm is deformed towards the air chamber with smaller air pressure, and the deformation of the elastic diaphragm 12 can change the opening and closing states of the opening and closing hole H12 and the air leakage hole H11b, namely when the air pressure in the first air chamber H100 is greater than the air pressure in the second air chamber H110, the elastic diaphragm 12 is deformed upwards to open the opening and closing hole H12 to close the air leakage hole H11b, when the air pressure in the second air chamber H110 is greater than the air pressure in the first air chamber H100, the elastic diaphragm 12 is deformed downwards to close the opening and closing hole H12 to open the air leakage hole H11b, so that the states of the opening and closing hole H12 and the air leakage hole H11b are changed through the deformation of the elastic diaphragm 12, and further the inflation or deflation is switched.

In a specific application, the inflation and deflation air pump can be applied to electronic equipment such as an intelligent sports watch or an electronic sphygmomanometer, and the inflation inlet H11a can be connected to an air bag of the electronic equipment.

When the inflation device is used for inflating, the driving mechanism drives the leather cup 2011 on the diaphragm piece 201 to compress or extend to reset, the air suction action is generated to suck air (the leather cup 2011 extends to reset) into the leather cup 2011, the air in the leather cup 2011 is discharged into the first air chamber H100 through the normally-closed one-way valve 13 through the exhaust action (the leather cup 2011 compresses), the elastic diaphragm 12 deforms upwards, the opening and closing hole H12 is opened, the air leakage hole H11b is sealed, therefore, the air in the first air chamber H100 can enter the second air chamber H110 through the opening and closing hole H12, the inflation hole H11a of the rethread is inflated into the air receiving device, and therefore the inflation of the air receiving device is achieved.

When the air needs to be discharged, the driving mechanism stops working, the air in the air receiving equipment flows back to the second air chamber H110, the elastic diaphragm 12 is forced to deform downwards to reset, the opening and closing hole H12 is closed again, and the air release hole H11b is opened, so that the air in the second air chamber H110 is directly discharged through the air release hole H11b, and the air discharging of the air receiving equipment is realized.

According to the inflation/deflation air pump provided by the embodiment of the invention, air is sucked in through the air suction action of the diaphragm pump body 20, the air is exhausted through the air exhaust action, and then the air is inflated into the first air chamber H100 through the normally closed one-way valve 13, the air pressure in the first air chamber H100 is increased, the elastic membrane 12 deforms upwards to open the opening and closing hole H12 and close the air escape opening H11b, at the moment, the air can enter the second air chamber H110 from the first air chamber H100, and the air receiving equipment is inflated through the air inflation opening H11a, so that the air receiving equipment is inflated; and when the diaphragm pump body 20 stops working, the air receiving equipment deflates, the air in the air receiving equipment enters the second air chamber H110, the air pressure in the second air chamber H110 is increased, the elastic diaphragm 12 deforms downwards to close the opening and closing hole H12 and open the air release hole H11b, at the moment, the air is directly discharged through the air release hole H11b of the second air chamber H110, the air is deflated for the air receiving equipment, so that the inflation and deflation functions can be realized under the condition that other configurations are not needed, for the related technology, the configurations of the air release valve and related air release pipelines, the control circuit and the like can be reduced, the watch structure is simplified, the cost is reduced, and meanwhile, the deflation function is more stable and reliable.

Referring to fig. 3 and 4, in some embodiments of the invention, the bottom of the cup 2011 is provided with a one-way valve 2011a configured to open during the intake action and close during the exhaust action.

In this embodiment, the one-way valve plate 2011a is directly arranged at the bottom of the leather cup 2011, the one-way valve plate 2011a keeps closed when the leather cup 2011 is compressed, the normally-closed one-way valve 13 on the valve plate 10 is opened, and other parts in the leather cup 2011 can be directly filled into the first air chamber H100 through the normally-closed one-way valve 13. And the type check valve 13 that closes is often drawn to leather cup 2011 and is closed, at this moment, form the negative pressure in the leather cup 2011 and make one-way valve block 2011a warp in to the leather cup 2011 and open, so, can follow the outside suction gas of leather cup 2011, from this, the reciprocating compression of leather cup 2011 is tensile can form reliable stable action of breathing in and the action of exhausting, and, this kind of structural design, the structure is extremely simple, need not set up the complicated gas circuit of breathing in, not only simplified the structure, saved the cost, and improved and breathed in, carminative stability and reliability.
