Description

Technical Field

[0001] The invention relates to an air pump, and in particular to an air charging and discharging air pump and an intelligent sports watch having the air pump. Background Art

[0002] Some electronic devices need to be inflated with air pumps, such as smart sports watches and electronic blood pressure monitors. However, for these electronic devices, the inflation volume is small, and diaphragm air pumps are usually used as inflation devices. When deflated, a deflation valve, such as a solenoid valve, is usually used to discharge the gas filled in the electronic device. This design has a complex structure and requires the configuration of an independent deflation valve, the arrangement of a deflation gas path to connect the deflation valve, and the design of a control circuit for control, which can also lead to problems such as low reliability and high cost. Summary of the invention

[0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. To this end, one object of the present invention is to provide an air pump for charging and discharging air and a smart sports watch having the same.

[0004] To achieve the above object, on the one hand, an air pump for charging and discharging air according to an embodiment of the present invention includes:

[0008] The elastic diaphragm has an opening and closing hole, and when the air pressure in the first air chamber increases, the elastic diaphragm deforms upward to open the opening and closing hole and close the air leakage port, and when the air pressure in the second air chamber increases, the elastic diaphragm deforms downward to close the opening and closing hole and open the air leakage port.

[0009] In addition, the inflation and deflation air pump according to the above embodiment of the present invention may also have the following additional technical features:

[0010] According to one embodiment of the present invention, a one-way valve is provided at the bottom of the leather cup, and the one-way valve is configured to open during the suction action and close during the exhaust action.

[0011] According to one embodiment of the present invention, the elastic diaphragm has a first tympanic membrane and a second tympanic membrane protruding toward the second air chamber, the opening and closing hole is provided on the first tympanic membrane, and a plug protruding toward the first air chamber on the valve plate closes the opening and closing hole;

[0012] In the inflated state, the gas in the diaphragm pump body flows into the first air chamber, forcing the first eardrum to deform upward to open the opening and closing hole, and the second eardrum to deform upward to seal the air leakage port; in the deflated state, the gas in the air receiving device flows back from the inflation port to the second air chamber, forcing the first eardrum to deform downward to seal the opening and closing hole, and the second eardrum to deform downward to open the air leakage port.

[0013] According to one embodiment of the present invention, the driving mechanism comprises:

[0014] A swing frame, wherein the swing frame has at least two connecting parts, at least two connecting parts correspond to at least two leather cups one by one, and each connecting part is connected to the bottom of the corresponding leather cup;

[0015] The connecting portion is provided with an air suction hole. When the leather cup is transformed from a compressed state to an extended state, the negative pressure in the leather cup causes the valve plate to deform upward to open the air suction hole, and gas is sucked in through the air suction hole.

[0016] An eccentric driving assembly is connected to the swing frame to drive the swing frame to swing back and forth so as to compress or stretch the leather cup.

[0017] According to one embodiment of the present invention, the valve plate has a plurality of valve holes, the plurality of valve holes are circumferentially spaced around a vertical axis, and a portion of the plurality of valve holes is communicated with a portion of at least two of the leather cups, and another portion of the plurality of valve holes is communicated with another portion of at least two of the leather cups;

[0018] The normally closed one-way valve is an umbrella-shaped valve, the axis of the umbrella-shaped valve coincides with the vertical axis, and the inner umbrella surface of the umbrella-shaped valve abuts against the top surface of the valve plate to seal the plurality of valve holes.

[0019] According to one embodiment of the present invention, the pump head cover has a nozzle portion protruding toward the second air chamber, and the air vent penetrates downward through the nozzle portion. When the air pressure in the first air chamber increases, the second eardrum deforms upward and abuts against the nozzle portion to seal the air vent.

[0020] According to one embodiment of the present invention, the top of the plug has a conical positioning portion, the diameter of the conical positioning portion gradually decreases from bottom to top, and the opening and closing hole is sleeved on the conical positioning portion to form a seal.

[0021] According to one embodiment of the present invention, a circular groove is provided on the inner top surface of the pump head cover, the diameter of the circular groove is larger than the diameter of the plug, and the conical positioning portion is located in the circular groove and is coaxially arranged to limit the opening of the opening and closing hole through the circular groove.

[0024] Airbags;

[0025] As for the inflation and deflation air pump as described above, the inflation port of the inflation and deflation air pump is communicated with the airbag.

[0026] The inflation and deflation air pump and the smart sports watch provided by the embodiments of the present invention inhale gas through the suction action of the diaphragm pump body, discharge the gas through the exhaust action, and then fill it into the first air chamber through the normally closed one-way valve. The air pressure in the first air chamber increases, and the elastic diaphragm deforms upward to open the opening and closing hole and close the air release port. At this time, the gas can enter the second air chamber from the first air chamber and inflate the air-receiving device from the inflation port, thereby inflating the air-receiving device; when the diaphragm pump body stops working, the air-receiving device deflates, and the gas in the air-receiving device enters the second air chamber. The air pressure in the second air chamber increases, and the elastic diaphragm deforms downward to close the opening and closing hole and open the air release port. At this time, the gas is directly discharged through the air release port of the second air chamber, thereby deflation of the air-receiving device. In this way, the inflation and deflation functions can be realized without the need for other configurations. Compared with the related art, the configurations of the deflation valve and related deflation pipelines, control circuits, etc. can be reduced, the watch structure is simplified, and the cost is reduced.

[0074] The following describes in detail the inflation and deflation air pump and the smart sports watch according to the embodiments of the present invention with reference to the accompanying drawings.

[0075] Reference Figures 1 to 8 As shown, the inflation and deflation air pump provided according to an embodiment of the present invention includes a diaphragm pump body 20 and a diaphragm pump head.

[0076] Specifically, the diaphragm pump body 20 includes a diaphragm 201 and a driving mechanism. The diaphragm 201 has at least two leather cups 2011. The driving mechanism is connected to the diaphragm 201 to drive the leather cups 2011 to alternately generate suction and exhaust actions. The driving mechanism drives the diaphragm 201 to move, thereby compressing the leather cups 2011 or stretching the leather cups 2011. When the leather cups 2011 are stretched, the suction action is completed, and when the leather cups 2011 are compressed, the exhaust action is completed. This reciprocating process can form a continuous alternating suction action and exhaust action.

[0077] The diaphragm pump head includes a valve plate 10, a pump head cover 11, an elastic diaphragm 12 and a normally closed one-way valve 13. The valve plate 10 is arranged on the diaphragm pump body 20 and seals the leather cup 2011. The pump head cover 11 is located above the valve plate 10. The pump head cover 11 has an inflation port H11a and an air release port H11b. The inflation port H11a is used to inflate an external gas-receiving device, such as a smart sports watch, an electronic blood pressure monitor, etc. The air release port H11b is used to deflate the gas-receiving device. The gas in the gas-receiving device can flow back to the diaphragm pump head and then be discharged from the air release port H11b.

[0078] The elastic diaphragm 12 is sealed between the valve plate 10 and the pump head cover 11, and 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 gas in the diaphragm pump body 20 to enter the first air chamber H100 in one direction.

[0079] The elastic diaphragm 12 has an opening and closing hole H12, and when the air pressure in the first air chamber H100 increases, the elastic diaphragm 12 deforms upward to open the opening and closing hole H12 and close the air leakage port H11b, and when the air pressure in the second air chamber H110 increases, the elastic diaphragm 12 deforms downward to close the opening and closing hole H12 and open the air leakage port H11b. Preferably, the elastic diaphragm 12 can generally be made of elastic plastic material, such as silicone, rubber, silicone rubber, fluororubber, nitrile rubber, chloroprene rubber and the like.

[0080] That is to say, the normally closed one-way valve 13 on the valve plate 10 remains in a normally closed state. When the first air chamber H100 is not inflated, the elastic diaphragm 12 remains in its original state, the opening and closing hole H12 remains closed, the air vent H11b remains open, and there is no communication between the first air chamber H100 and the second air chamber H110. The elastic diaphragm 12 is elastic and 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 equilibrium state of the elastic diaphragm 12 is broken and it will deform toward the air chamber with smaller air pressure. The deformation of the elastic diaphragm 12 can change the switching state of the opening and closing hole H12 and the air leakage port H11b, that is, 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 deforms upward to open the opening and closing hole H12 and close the air leakage port 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 deforms downward to close the opening and closing hole H12 and open the air leakage port H11b. In this way, the states of the opening and closing hole H12 and the air leakage port H11b are changed by the deformation of the elastic diaphragm 12, thereby switching between inflation and deflation.

[0081] In a specific application, the inflation and deflation air pump can be applied to electronic devices such as smart sports watches or electronic blood pressure monitors, and the inflation port H11a can be connected to the airbag of the electronic device.

[0082] During inflation, the driving mechanism drives the leather cup 2011 on the diaphragm 201 to compress or extend and reset, generating an intake action to inhale gas (leather cup 2011 extends and resets) into the leather cup 2011, and then through an exhaust action (leather cup 2011 is compressed), the gas in the leather cup 2011 is discharged into the first air chamber H100 through the normally closed one-way valve 13, and the elastic diaphragm 12 is deformed upward to open the opening and closing hole H12 and close the air leakage port H11b. In this way, the gas in the first air chamber H100 can enter the second air chamber H110 through the opening and closing hole H12, and then be filled into the air receiving device through the inflation port H11a, thereby inflating the air receiving device.

[0083] When deflation is required, the driving mechanism stops working, and the gas in the gas-receiving device flows back to the second air chamber H110, forcing the elastic diaphragm 12 to deform downward and reset, re-closing the opening and closing hole H12 and opening the deflation port H11b. In this way, the gas in the second air chamber H110 is directly discharged through the deflation port H11b, thereby deflation of the gas-receiving device.

[0084] According to the inflatable and deflation air pump provided by the embodiment of the present invention, gas is sucked in through the suction action of the diaphragm pump body 20, and the gas is discharged through the exhaust action, and then filled into the first air chamber H100 through the normally closed one-way valve 13. The air pressure in the first air chamber H100 increases, and the elastic diaphragm 12 deforms upward to open the opening and closing hole H12 to close the air release port H11b. At this time, the gas can enter the second air chamber H110 from the first air chamber H100 and inflate the air receiving device from the inflation port H11a, thereby inflating the air receiving device; when the diaphragm pump body 20 stops working, the air receiving device is deflated. The gas in the air receiving device enters the second air chamber H110, the air pressure in the second air chamber H110 increases, the elastic diaphragm 12 deforms downward to close the opening and closing hole H12 and open the air vent H11b. At this time, the gas is directly discharged through the air vent H11b of the second air chamber H110 to deflate the air receiving device. In this way, the inflation and deflation functions can be realized without the need for other configurations. Compared with related technologies, the configurations of the deflation valve and related deflation pipelines, control circuits, etc. can be reduced, thereby simplifying the watch structure and reducing costs. At the same time, the deflation function is more stable and reliable.

[0085] Reference Figure 3 and Figure 4 As shown, in some embodiments of the present invention, a one-way valve sheet 2011a is provided at the bottom of the leather cup 2011, and the one-way valve sheet 2011a is configured to open during the suction action and close during the exhaust action.

[0086] In this embodiment, a one-way valve sheet 2011a is directly provided at the bottom of the leather cup 2011. When the leather cup 2011 is compressed, the one-way valve sheet 2011a remains closed, while the normally closed one-way valve 13 on the valve plate 10 is opened, and the other gas in the leather cup 2011 can be directly filled into the first air chamber H100 through the normally closed one-way valve 13. When the leather cup 2011 is stretched, the normally closed one-way valve 13 is closed. At this time, negative pressure is formed in the leather cup 2011, causing the one-way valve sheet 2011a to deform and open toward the leather cup 2011. In this way, gas can be sucked from the outside of the leather cup 2011. Thus, the leather cup 2011 can form a reliable and stable suction and exhaust action by reciprocating compression and stretching. Moreover, this structural design is extremely simple in structure and does not require a complex suction gas path. It not only simplifies the structure and saves costs, but also improves the stability and reliability of suction and exhaust.

[0087] Reference Figure 3 and Figures 6 to 8 As shown, in one embodiment of the present invention, the elastic diaphragm 12 has a first eardrum 122a and a second eardrum 122b protruding toward the second air chamber H110, the opening and closing hole H12 is arranged on the first eardrum 122a, and the plug 101 protrudes toward the first air chamber H100 on the valve plate 10, and the plug 101 closes the opening and closing hole H12.

[0088] In the inflated state, the gas in the diaphragm pump body 20 flows into the first air chamber H100, forcing the first eardrum 122a to deform upward and open the opening and closing hole H12, and the second eardrum 122b to deform upward and seal the air leakage port H11b; in the deflated state, the gas in the gas receiving device flows back from the inflation port H11a to the second air chamber H110, forcing the first eardrum 122a to deform downward and seal the opening and closing hole H12, and the second eardrum 122b to deform downward and open the air leakage port H11b.

[0089] That is to say, in this embodiment, the first eardrum 122a and the second eardrum 122b are spaced apart on the elastic diaphragm 12, and the first eardrum 122a and the second eardrum 122b can be deformed up and down under gas pressure, wherein the first eardrum 122a can cooperate with the plug 101 when deformed to realize the control of opening and closing of the opening and closing hole H12 on the first eardrum 122a, thereby realizing the communication control between the first air chamber H100 and the second air chamber H110. When the first air chamber H100 and the second air chamber H110 are connected, the gas in the first air chamber H100 can be filled into the second air chamber H110, and then inflated through the inflation port H11a of the second air chamber H110. The second eardrum 122b can be used to control the opening and closing of the air vent H11b in the second air chamber H110. When the air vent H11b is closed, the normal inflation state is ensured. When the air vent H11b is opened and the opening and closing hole H12 is closed, the gas in the air receiving device is allowed to enter the second air chamber H110 and then be discharged through the air vent H11b, thereby realizing the control switching between the inflation state and the deflation state.

[0090] Specifically, when inflating, the diaphragm pump body 20 inflates air into the first air chamber H100. At this time, the air pressure in the first air chamber H100 increases. The increase in air pressure forces the first eardrum 122a and the second eardrum 122b to deform upward. The first eardrum 122a deforms upward, thereby separating the first eardrum 122a from the plug 101, thereby opening the opening and closing hole H12. The second eardrum 122b deforms upward and can be pressed against the inner wall of the pump head cover 11 to close the air leakage port H11b. In this way, the gas in the first air chamber H100 can enter the second air chamber H110 through the opening and closing hole H12. Since the air leakage port H11b in the second air chamber H110 is closed by the second eardrum 122b, at this time, the gas in the second air chamber H110 can only be filled into the air receiving device through the inflation port H11a, thereby inflating the air receiving device.

[0091] When deflation occurs, the diaphragm pump body 20 stops working, and the gas in the air-receiving equipment flows back to the second air chamber H110, which increases the air pressure in the second air chamber H110, forcing the first eardrum 122a and the second eardrum 122b to deform and reset downward. The first eardrum 122a then resets downward and adheres to the plug 101. The plug 101 can reclose the opening and closing hole H12, and the second eardrum 122b deforms and resets downward and can be separated from the inner wall of the pump head cover 11 to open the air vent H11b. In this way, the gas in the second air chamber H110 can only be discharged through the air vent H11b, thereby achieving deflation of the air-receiving equipment.

[0092] In this embodiment, by configuring the first eardrum 122a and the second eardrum 122b, this eardrum structure design is more easily deformed upward, and in the initial state, the opening and closing hole H12 is kept closed and the air release port H11b is kept open, ensuring that the inflation and deflation functions can be switched reliably and stably.

[0093] Reference Figure 3 to Figure 4 As shown, in one embodiment of the present invention, the driving mechanism includes a swing frame 205 and an eccentric driving assembly, the swing frame 205 has at least two connecting parts 2051, at least two of the connecting parts 2051 correspond one-to-one to at least two of the leather cups 2011, and each of the connecting parts 2051 is connected to the bottom of the corresponding leather cup 2011.

[0094] The connecting portion 2051 is provided with an air intake hole H205. When the leather cup 2011 is transformed from a compressed state to an extended state, the negative pressure in the leather cup 2011 forces the valve plate 2011a to deform upward to open the air intake hole H205, and gas is sucked in through the air intake hole H205.

[0095] The eccentric drive assembly is connected to the swing frame to drive the swing frame to swing back and forth to compress or stretch the leather cup 2011. The eccentric drive assembly may include a pump seat 203, a motor 202 and an eccentric wheel 204, wherein the diaphragm 201 is mounted on the top of the pump seat 203, the motor 202 is mounted on the bottom of the pump seat 203, the eccentric wheel 204 is mounted on the output shaft of the motor 202, and the swing frame 205 is connected to the eccentric wheel 204 via an oblique pin 206.

[0096] When the motor 202 is working, the motor 202 drives the eccentric wheel 204 to rotate, and the oblique pin 206 on the eccentric wheel 204 can drive the swing frame 205 to swing back and forth in a circumferential direction, and the connecting portion 2051 on the swing frame 205 can produce a compression or tension effect on the upper leather cup 2011, and part of the leather cup 2011 is compressed, while the other part of the leather cup 2011 is stretched. When the leather cup 2011 is stretched, since the normally closed one-way valve 13 remains closed, a negative pressure is formed in the leather cup 2011. Under the action of the negative pressure, the one-way valve sheet 2011a at the bottom of the leather cup 2011 is deformed into the leather cup 2011 and separated from the upper end of the connecting portion 2051. , open the air intake hole H205 on the connecting part 2051, and the external gas can enter into the leather cup 2011. When the leather cup 2011 is compressed, the air pressure in the leather cup 2011 increases, forcing the one-way valve sheet 2011a at the bottom of the leather cup 2011 to be tightly attached to the upper end of the connecting part 2051, keeping the air intake hole H205 closed, and the normally closed one-way valve 13 on the valve plate 10 is opened by the gas pressure, and the gas in the leather cup 2011 can be filled into the first air chamber H100 through the normally closed one-way valve 13. In this way, a complete air intake and exhaust action can be completed, and the first air chamber H100 can be automatically inflated.

[0097] In this embodiment, the above-mentioned structural design is adopted, which simply realizes the intake and exhaust of air through the cooperation of the connecting part 2051 with the one-way valve plate 2011a at the bottom of the leather cup 2011, and the cooperation of the normally closed one-way valve 13. The structure is simple, which ensures effective and sufficient inflation every time, and the inflation process is stable and efficient, with reliable performance and low cost.

[0098] Reference Figure 3 and Figures 7 and 8 As shown, in one embodiment of the present invention, the valve plate 10 has a plurality of valve holes H10, the plurality of valve holes H10 are circumferentially spaced around a vertical axis, and a portion of the plurality of valve holes H10 is communicated with a portion of at least two of the leather cups 2011, and another portion of the plurality of valve holes H10 is communicated with another portion of at least two of the leather cups 2011. The normally closed one-way valve 13 is an umbrella valve, the axis of the umbrella valve coincides with the vertical axis, and the inner umbrella surface of the umbrella valve abuts against the top surface of the valve plate 10 to seal the plurality of valve holes H10.

[0099] That is to say, in the initial state, the inner umbrella surface of the umbrella valve is against the top surface of the valve plate 10, thereby closing the multiple valve holes H10 on the valve plate 10. When the leather cup 2011 is compressed, the air pressure in the leather cup 2011 increases, and the one-way valve sheet 2011a at the bottom of the leather cup 2011 is against the upper end of the connecting portion 2051 to close the air intake hole H205. At the same time, the gas in the leather cup 2011 enters the valve hole H10 to generate an upward force on the umbrella valve, forcing the umbrella valve to deform upward and open the valve hole H10, so that the gas can enter the first air chamber H100 through the valve hole H10. When the leather cup 2011 is stretched and reset, negative pressure is formed inside the leather cup 2011, and negative pressure is also formed inside the valve hole H10, forcing the inner umbrella surface of the umbrella valve to be adsorbed on the top surface of the valve plate 10, closing the valve hole H10. At the same time, under the action of negative pressure, the one-way valve sheet 2011a at the bottom of the leather cup 2011 is deformed upward to open the suction hole H205, so that external air can be sucked into the leather cup 2011.

[0100] In this embodiment, the above-mentioned normally closed one-way valve 13 is used, which is connected to each leather cup 2011 through multiple valve holes H10, and each valve hole H10 is opened and closed by an umbrella valve. It has a simple structure and reliable one-way conduction performance. Through the cooperation of the umbrella valve and the one-way valve sheet 2011a at the bottom of the leather cup 2011, effective air intake and exhaust actions can be achieved, and the inflation efficiency is high.

[0101] Reference Figure 6 and Figure 8 As shown, in one embodiment of the present invention, the pump head cover 11 has a nozzle portion 111 protruding toward the second air chamber H110, and the air leakage port H11b penetrates downwardly through the nozzle portion 111. When the air pressure in the first air chamber H100 increases, the second eardrum 122b deforms upward and abuts against the nozzle portion 111 to seal the air leakage port H11b.

[0102] In this embodiment, a nozzle portion 111 communicated with the air leak port H11b is provided on the inner top surface of the second air chamber H110. Since the nozzle portion 111 protrudes downward, when the first air chamber H100 is inflated, the second eardrum 122b is deformed upward and easily abuts against the nozzle portion 111, thereby sealing the nozzle portion 111 and closing the air leak port H11b. In this way, the reliability and stability of the closing of the air leak port H11b are ensured.

[0103] Reference Figure 3 and Figures 6 to 8 As shown, in one embodiment of the present invention, the plug 101 is cylindrical, the diameter of the plug 101 is larger than the diameter of the opening and closing hole H12, and the plug 101 is located below the opening and closing hole H12 and abuts against the first eardrum 122a to seal the opening and closing hole H12.

[0104] That is to say, in this embodiment, the plug 101 which is larger than the diameter of the opening and closing hole H12 is used to press the first eardrum 122a upward, so that the opening and closing hole H12 on the first eardrum 122a is closed. In this way, this structural design can not only ensure that the opening and closing hole H12 can be closed, but also ensure that when the first air chamber H100 is inflated and the first eardrum 122a is deformed upward, the part around the opening and closing hole H12 can be quickly and timely pushed open, thereby opening the opening and closing hole H12, thereby improving the reliability of opening the opening and closing hole H12.

[0105] In one embodiment of the present invention, the top of the plug 101 has a conical positioning portion 1011, the diameter of the conical positioning portion 1011 gradually decreases from bottom to top, and the opening and closing hole H12 is sleeved on the conical positioning portion 1011 to form a seal.

[0106] In this embodiment, the conical positioning portion 1011 and the opening and closing hole H12 are sleeved together, for example, the circumference of the opening and closing hole H12 is in close contact with the conical surface of the conical positioning portion 1011 to form a seal, so that a good sealing effect can be achieved, and when the first air chamber H100 is inflated, the circumference of the opening and closing hole H12 is separated from the conical surface of the conical positioning portion 1011 to form a gap, thereby realizing the opening of the opening and closing hole H12. This matching structure can always maintain the relative position relationship between the conical positioning portion 1011 and the opening and closing hole H12 during the opening and closing process. For example, the conical positioning portion 1011 and the opening and closing hole H12 remain coaxial, thereby ensuring that the opening and closing of the opening and closing hole H12 are very reliable.

[0107] Reference Figures 6 to 8 As shown, in one embodiment of the present invention, the elastic diaphragm 12 is made of elastic colloid material, and includes a frame portion 121 and a diaphragm portion 122, the frame portion 121 is clamped between the valve plate 10 and the pump head cover 11; the diaphragm portion 122 is formed inside the frame portion 121, and the first eardrum 122a and the second eardrum 122b are formed by protruding upward from two local positions on the diaphragm portion 122.

[0108] That is, the elastic diaphragm 12 is mainly composed of a frame portion 121 and a diaphragm portion 122. The frame portion 121 is thicker and is sandwiched between the valve plate 10 and the pump head cover 11, so as to easily form a sealed state. The diaphragm portion 122 is formed inside the frame portion 121 and is thinner. A first tympanic membrane 122a and a second tympanic membrane 122b protruding upward are formed on the diaphragm portion 122. In this way, the first tympanic membrane 122a and the second tympanic membrane 122b with thinner thickness are more likely to deform upward, thereby stably opening the opening and closing hole H12 and closing the air leakage port H11b.

[0109] Preferably, a resisting portion 123 is provided on the top surface of the diaphragm portion 122, and the resisting portion 123 is located between the first eardrum 122a and the second eardrum 122b and resists the pump head cover 11. In this way, through the resisting portion 123 and the pump head cover 11, it can be ensured that when the first air chamber H100 is inflated, only the first eardrum 122a and the second eardrum 122b are deformed upward, and the part between the first eardrum 122a and the second eardrum 122b cannot be deformed upward due to the resisting effect of the resisting portion 123 and the pump head cover 11. Therefore, when the first air chamber H100 is inflated, the first eardrum 122a and the second eardrum 122b on the diaphragm portion 122 are accurately deformed upward, further improving its opening and closing control effect on the opening and closing hole H12 and the air leakage port H11b.

[0110] Reference Figure 6 and Figure 8 As shown, in one embodiment of the present invention, a circular groove H11c is provided on the inner top surface of the pump head cover 11, the diameter of the circular groove H11c is larger than the diameter of the plug 101, and the conical positioning portion 1011 is located in the circular groove H11c and is coaxially arranged to limit the opening of the opening and closing hole H12 when it is opened through the circular groove H11c. Preferably, when the periphery of the opening and closing hole H12 is sleeved on the conical positioning portion 1011, there is a predetermined gap between the outer surface of the periphery of the opening and closing hole H12 and the opening of the circular groove H11c, and the predetermined gap can limit the outward deformation of the periphery of the opening and closing hole H12, thereby limiting the opening.

[0111] In this embodiment, by setting a circular groove H11c on the inner top surface of the pump head cover 11 and utilizing the positional relationship between the prototype groove and the conical positioning portion 1011 and the opening and closing hole H12, the opening degree of the opening and closing hole H12 can be limited, ensuring that the opening and closing control of the opening and closing hole H12 can remain stable even after long-term use, with a long service life and stable and reliable performance.

[0112] Preferably, the longitudinal cross-section of the first eardrum 122a and the second eardrum 122b is an arc convex upwardly. This arc convex structure is easy to deform upwardly in the direction of the arc after being affected by air pressure and ensures that the center position of the arc is in close contact with the plug 101 and the pump head cover 11.

[0113] An embodiment of the present invention further provides a smart sports watch, comprising an airbag and an inflation / deflation air pump as described in the above embodiment, wherein an inflation port H11a of the inflation / deflation air pump is connected to the airbag.

[0114] The smart sports watch provided according to an embodiment of the present invention has the inflation and deflation air pump of the above embodiment, which can realize the inflation and deflation functions without the need for other configurations. Compared with the related art, it can reduce the configuration of the deflation valve and related deflation pipelines, control circuits, etc., simplify the watch structure, and reduce costs. At the same time, the deflation function is more stable and reliable.
