The inflation and deflation air pump and the intelligent sports watch according to the embodiment of the invention are described in detail below with reference to the accompanying drawings.
Referring to fig. 1 to 8, an inflation and deflation air pump according to an embodiment of the present invention includes a diaphragm pump body 20 and a diaphragm pump head.
Specifically, the diaphragm pump body 20 includes a diaphragm member 201 and a driving mechanism, where the diaphragm member 201 has at least two cups 2011, and the driving mechanism is connected to the diaphragm member 201 and is used to drive the cups 2011 to alternately generate an air suction action and an air discharge action. The driving mechanism drives the diaphragm member 201 to move, so that the cup 2011 is compressed or stretched, the suction action is completed when the cup 2011 is stretched, and the exhaust action is completed when the cup 2011 is compressed, so that the cup is reciprocated, and the suction action and the exhaust action can be continuously and alternately formed.
The diaphragm pump head comprises a valve plate 10, a pump head cover 11, an elastic diaphragm 12 and a normally-closed one-way valve 13, wherein the valve plate 10 is arranged on the diaphragm pump body 20 and seals the leather cup 2011, the pump head cover 11 is positioned above the valve plate 10, and the pump head cover 11 is provided with an inflation port H11a and an deflation port H11b. The inflation inlet H11a is used for inflating an external air-receiving device, such as a smart sports watch, an electronic sphygmomanometer, and the like. The air leakage port H11b is used for discharging air from the air receiving device, and air in the air receiving device can flow back to the diaphragm air pump head and then is discharged from the air leakage port H11b.
An elastic diaphragm 12 is hermetically disposed between the valve plate 10 and the pump head cover 11, a first air chamber H100 is defined between the elastic diaphragm 12 and the valve plate 10, and a second air chamber H110 is defined between the elastic diaphragm 12 and the pump head cover 11. A normally closed one-way valve 13 is provided on the valve plate 10 to control the one-way entry of the gas in the diaphragm pump body 20 into the first gas chamber H100.
The elastic membrane 12 has a hole H12, and when the air pressure in the first air chamber H100 increases, the elastic membrane 12 deforms upward to open the opening/closing hole H12 to close the air leakage hole H11b, and when the air pressure in the second air chamber H110 increases, the elastic membrane 12 deforms downward to close the opening/closing hole H12 to open the air leakage hole H11b. Preferably, the elastic membrane 12 is made of elastic plastic, such as silica gel, rubber, silicone rubber, fluororubber, nitrile rubber, neoprene, 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 membrane 12 is kept in an original state, the opening hole H12 is kept closed, the air leakage port H11b is kept open, and no communication is made between the first air chamber H100 and the second air chamber H110. The elastic membrane 12 has elasticity, and the elastic membrane 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 air pressure in the second air chamber H110 are changed, the balance state of the elastic membrane 12 is broken, the elastic membrane 12 is deformed towards the air chamber with smaller air pressure, the deformation of the elastic membrane 12 can change the opening and closing state of the opening and closing hole H12 and the air release 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 membrane 12 is deformed upwards to open the opening and closing hole H12 to close the air release hole H11b, and when the air pressure in the second air chamber H110 is greater than the air pressure in the first air chamber H100, the elastic membrane 12 is deformed downwards to close the opening and closing hole H12 to open the air release hole H11b, so the state of the opening and the air release hole H11b is changed through the deformation of the elastic membrane 12, and inflation or deflation is further 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 inflatable device is inflated, the driving mechanism drives the leather cup 2011 on the diaphragm piece 201 to compress or stretch and reset, suction gas is generated to suck the leather cup 2011 (the leather cup 2011 stretches and resets) to the leather cup 2011, then the gas 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 opening H11b is closed, and therefore the gas in the first air chamber H100 can enter the second air chamber H110 through the opening hole H12, and then the gas is filled into the air receiving equipment through the air filling opening H11a, so that the inflatable device is inflated.
When the air is required to be discharged, the driving mechanism stops working, air in the air receiving equipment flows back to the second air chamber H110, the elastic membrane 12 is forced to deform downwards for resetting, the opening hole H12 is closed again, the air discharging port H11b is opened, and therefore the air in the second air chamber H110 is directly discharged through the air discharging port H11b, and the air discharging of the air receiving equipment is achieved.
According to the inflation and deflation air pump provided by the embodiment of the invention, air is sucked through the air suction action of the diaphragm pump body 20, and is exhausted through the air exhaust action, 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 diaphragm 12 is deformed upwards to open the opening and closing hole H12 and close the air release hole H11b, at the moment, the air can enter the second air chamber H110 from the first air chamber H100 and is inflated for the air receiving equipment from the air inflation hole H11a, so that the air receiving equipment is inflated, and when the diaphragm pump body 20 stops working, the air receiving equipment is deflated, 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 is deformed downwards to close the opening hole H11b, and at the moment, the air is directly exhausted through the air release hole H11b of the second air chamber H110, and thus the inflation and deflation functions of the air receiving equipment can be realized, compared with the related technology, the inflation and deflation air receiving equipment can be reduced, the control and the air release equipment is simplified, the air release circuit is configured, the cost is reduced, and the structure is stable.
Referring to fig. 3 and 4, in some embodiments of the present invention, a check valve 2011a is provided at the bottom of the cup 2011, and the check valve 2011a is configured to be opened during the suction operation and closed during the discharge operation.

The normally closed one-way valve 13 is closed when the leather cup 2011 is stretched, at the moment, negative pressure is formed in the leather cup 2011 to enable the one-way valve sheet 2011a to deform and open towards the inside of the leather cup 2011, so that gas can be sucked from the outside of the leather cup 2011, and the leather cup 2011 can be compressed and stretched in a reciprocating mode to form reliable and stable suction action and exhaust action.
Referring to fig. 3 and 6 to 8, in one embodiment of the present invention, the elastic membrane 12 has a first tympanic membrane 122a and a second tympanic membrane 122b protruding toward the second air chamber H110, the opening and closing hole H12 is provided on the first tympanic membrane 122a, the plug 101 protruding toward the first air chamber H100 is provided on the valve plate 10, and the plug 101 closes the opening and closing hole H12.
