Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as a limitation of this patent. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to the specific circumstances.

[0021] In one embodiment, Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, an air pump 10 for charging and discharging air in one body comprises an upper shell assembly 100, a charging and discharging assembly 200 and a motor 300; the upper shell assembly 100 comprises a first shell 110 and a second shell 120, the first shell 110 is connected to the second shell 120, the first shell 110 is provided with an air outlet 111, the second shell 120 is provided with a first air release hole 121 and an air inlet hole 122, the air outlet 111 is connected to the first air release hole 121 and the air inlet hole 122; the charging and discharging assembly 200 comprises an upper cover 210, a lower cover 220, a rubber bowl 230, a bracket 240, a piston structure 250 and a lifting eccentric wheel 260, the rubber bowl 230 is provided on the upper cover 210, the upper cover 210 is connected to the second shell 120, and the rubber bowl 230 is aligned with the Air inlet 122; the rubber bowl 230 is arranged at one end of the bracket 240, and the other end of the bracket 240 is arranged on the lifting eccentric wheel 260, and the lifting eccentric wheel 260 is rotatably arranged on the lower cover 220; the rubber bowl 230 is provided with a second air release hole 231, and the upper cover 210 is provided with a third air release hole 211, the first air release hole 121, the second air release hole 231 and the third air release hole 211 are aligned and connected, the piston structure 250 is provided on the side of the third air release hole 211 facing away from the rubber bowl 230, and the piston structure 250 movably seals the third air release hole 211, and the bracket 240 abuts against the piston structure 250; the motor 300 is connected to the lower cover 220, and the motor 300 is drivingly connected to the lifting eccentric wheel 260.

[0022] Specifically, by setting a lifting eccentric wheel 260 in the air-inflating and air-discharging integrated pump, and the lifting eccentric wheel 260 can be raised or lowered by the forward and reverse rotation of the motor 300, the bracket 240 can be driven to rise or fall by the rising or falling of the lifting eccentric wheel 260, and the bracket 240 is movably abutted against the piston structure 250, so as to control whether the third air release hole 211 is opened. Specifically, when the power supply is positively connected to the motor 300, the motor 300 will drive the lifting eccentric wheel 260 to rotate forward, and the lifting eccentric wheel 260 will rise when it rotates forward, thereby driving the bracket 240 to rotate and rise, and the raised bracket 240 will abut against the piston structure 250 to seal the third air release hole 211, and the rotating bracket 240 will drive the rubber bowl 230 to inflate, thereby realizing the inflation function of the air-inflating and air-discharging integrated pump. When the power supply is reversed to the motor 300, the motor 300 will drive the lifting eccentric wheel 260 to reverse, and the reverse rotation of the lifting eccentric wheel 260 will lower, thereby driving the bracket 240 to lower. The lowered bracket 240 will not abut the piston structure 250, making it impossible for the piston structure 250 to seal the third vent hole 211, thereby achieving the deflation function. The integrated inflation and deflation pump provided by the present invention, through the built-in inflation and deflation component 200, can achieve inflation or deflation by controlling the forward or reverse rotation of the motor 300, without the need for an external air valve, thus saving space.

[0023] In this embodiment, since the first air release hole 121, the second air release hole 231, and the third air release hole 211 are connected, and the first air release hole 121 is connected to the air outlet 111, the air outlet 111 is connected to the third air release hole 211. When the third air release hole 211 is blocked, gas cannot be discharged from the air outlet 111 through the third air release hole 211. When the third air release hole 211 is not blocked, gas can be discharged from the air outlet 111 through the third air release hole 211.

[0024] In one embodiment, the lifting eccentric 260 includes an eccentric lower cover and an eccentric lower cover, the middle protrusion of the eccentric lower cover is provided with a connecting shaft, the upper cover 210 of the lifting eccentric 260 is provided with a connecting groove, and the connecting shaft is inserted into the connecting groove; the outer periphery of the eccentric lower cover is provided with an annular slope and a blocking block, the height of the annular slope gradually decreases from one side of the blocking block to the other side of the blocking block, the side protrusion of the eccentric lower cover is provided with a protrusion, and the protrusion is slidably provided on the annular slope. Specifically, when the power electrode is connected to the motor 300, the motor 300 drives the eccentric lower cover to rotate in one direction, and when the eccentric lower cover rotates to the point where one side of the blocking block abuts against one side of the protrusion of the eccentric lower cover, the eccentric lower cover will drive the eccentric lower cover to rotate. When the electrode is reversely connected to the motor 300, the motor 300 can be used to drive the eccentric lower cover to rotate in the other direction. When the eccentric lower cover rotates to the point where the other side of the blocking block contacts the other side of the protrusion of the eccentric lower cover, the eccentric lower cover will drive the eccentric lower cover to rotate. Since the annular slope is a slope arranged around the eccentric lower cover, that is, the heights of the annular slopes on both sides of the blocking block are different, and the protrusion of the eccentric lower cover is slidably arranged on the annular slope, when the motor 300 is connected in the forward and reverse directions, the height of the eccentric lower cover relative to the eccentric lower cover is different during the process of the eccentric lower cover being driven to rotate, thereby realizing the lifting function of the lifting eccentric 260.

[0025] In order to improve the wear resistance of the piston structure 250 and improve the sealing performance of the piston structure 250, in one embodiment, as shown in FIG. Figure 4 As shown, the piston structure 250 includes a metal block 251 and a plug 252. The plug 252 is provided with a receiving groove 253, and the metal block 251 is arranged in the receiving groove 253. Specifically, the receiving groove 253 is provided on the side of the plug 252 facing the bracket 240, and the metal block 251 is arranged in the receiving groove 253. The metal block 251 is movably abutted against the bracket 240, and the plug 252 is used to movably seal the third air outlet. By arranging the metal block 251 to abut against the bracket 240, since the bracket 240 needs to rotate, the wear resistance of the piston structure 250 can be improved by arranging the metal block 251 to abut against the bracket 240. The plug 252 is relatively soft and can better movably seal the third air outlet.

[0026] In this embodiment, the plug 252 is made of rubber or silicone, and the metal block 251 is made of copper. The use of rubber or silicone as the material for the plug 252 makes it relatively soft, thereby better sealing the third air outlet. The use of copper as the material for the metal block 251 provides it with greater wear resistance, thereby enhancing the wear resistance of the metal block 251 during the rotational contact between the bracket 240 and the metal block 251, thereby increasing the useful life of the metal block 251.

[0027] In order to allow the bracket 240 to rotate better during the contact process with the piston structure 250, in one embodiment, as shown in FIG. Figure 2 As shown, the bracket 240 is provided with a protruding conical bump 241, which abuts the piston structure 250. Specifically, the conical bump 241 is located in the middle of the bracket 240, and the top of the conical bump 241 is flat. When the bracket 240 and the piston structure 250 abut and rotate, the smaller contact area between the conical bump 241 and the piston structure 250 allows for better rotation and reduces wear between the bracket 240 and the piston structure 250.

[0028] In order to enable the piston structure 250 to accurately seal the third vent hole 211, in one embodiment, Figure 4 As shown, the upper cover 210 is provided with a blocking groove 213 on the side facing the lower cover 220, and the third vent hole 211 is provided at the bottom of the blocking groove 213. The blocking groove 213 is connected to the third vent hole 211. A cylindrical block 214 is provided around the notch of the blocking groove 213. The piston structure 250 is provided with a circular hole 254, and the cylindrical block 214 is correspondingly inserted into the circular hole 254. The piston structure 250 at least partially movably seals the blocking groove 213. Specifically, through the above arrangement, the piston structure 250 can be accurately installed at the notch of the blocking groove 213. In this way, the third vent hole 211 can be sealed by simply pushing the piston structure 250 toward the blocking groove 213.

[0029] In this embodiment, if Figure 4As shown, a circulation groove is provided on the groove wall of the blocking groove 213, and the circulation groove is connected to the blocking groove 213 and the third air vent 211. Specifically, when the piston structure 250 is inserted into the blocking groove 213 and seals the third air vent 211, the circulation groove and the blocking groove will be blocked and isolated by the piston structure 250, and at this time, the circulation groove and the blocking groove will not be connected. When the air pump 10 with integrated inflation and deflation needs to be deflated, the bracket 240 will no longer lift the piston structure 250. At this time, air flows into the blocking groove 213 through the circulation groove, thereby balancing the internal and external air pressures of the blocking groove; thereby allowing the piston structure 250 to quickly and naturally fall from the blocking groove 213 without being lifted by the bracket 240.

[0030] In order to allow the lifting eccentric wheel 260 to better drive the bracket 240 to rotate, in one embodiment, as shown in FIG. Figure 2 As shown, the lifting eccentric wheel 260 is provided with an eccentric hole 261, in which a steel ball 262 is disposed. One end of the bracket 240 is inserted into the lifting eccentric wheel 260, and the bracket 240 abuts against the steel ball 262. Specifically, by obliquely providing the eccentric hole 261 on the lifting eccentric wheel 260, the rotating shaft of the bracket 240 can be obliquely inserted into the eccentric hole 261. At the same time, by disposing the steel ball 262 in the eccentric hole 261, the friction between the bracket 240 and the lifting eccentric wheel 260 can be reduced, allowing the lifting eccentric wheel 260 to better drive the bracket 240 to rotate, reducing wear between the rotating shaft of the bracket 240 and the lifting eccentric wheel 260.

[0031] In order to align and install the rubber bowl 230 on the upper cover 210, in one embodiment, as shown in FIG. Figure 2 As shown, the upper cover 210 is provided with a raised limiting protrusion 212, and the corresponding position of the rubber bowl 230 is provided with a limiting groove 232, and the limiting protrusion 212 is disposed within the limiting groove 232. Specifically, the outer periphery of the upper cover 210 is provided with three raised limiting protrusions 212, and the outer periphery of the rubber bowl 230 is provided with three corresponding limiting grooves 232. When the rubber bowl 230 is installed on the upper cover 210, each limiting protrusion 212 will be disposed within a limiting groove 232. This arrangement allows the rubber bowl 230 to be accurately installed on the upper cover 210. This prevents the rubber bowl 230 from shifting when it is squeezed.

[0032] In order to allow the lifting eccentric wheel 260 to rotate better on the lower cover 220, in one embodiment, as shown in FIG. Figure 3As shown, the lower cover 220 is provided with a rotation groove, and a transmission hole 221 is provided at the bottom of the rotation groove. The lifting eccentric wheel 260 is rotatably arranged in the rotation groove, and the transmission shaft of the motor 300 passes through the transmission hole 221 and is drive-connected to the lifting eccentric wheel 260. Specifically, a mounting block is provided on the lifting eccentric wheel 260, and the mounting block is rotatably arranged in the rotation groove. At the same time, the lifting eccentric wheel 260 is provided with a drive hole at the position of the mounting block. The transmission shaft of the motor 300 passes through the transmission hole 221 and is inserted into the drive hole. This allows the motor 300 to drive the lifting eccentric wheel 260 to rotate better on the lower cover 220.

[0033] In order to prevent the gas from flowing back to the rubber bowl 230, in one embodiment, Figure 2 and Figure 3 As shown, the air pump 10 for charging and discharging gas further includes an umbrella-shaped valve 400. The second shell 120 is provided with a mounting hole 123. The air inlet 122 is provided around the mounting hole 123. The umbrella-shaped valve 400 is inserted into the mounting hole 123. The umbrella-shaped valve 400 movably seals the air inlet 122. Specifically, when the air pump 10 for charging and discharging gas is being inflated, the rubber bowl 230 will inflate the air inlet 122. The inflated gas will push up the umbrella-shaped valve 400. The lifted umbrella-shaped valve 400 no longer seals the air inlet 122, thereby allowing the air inlet 122 to pass through. The passed gas is finally discharged to the outside of the air pump 10 for charging and discharging gas through the air outlet 111. When the integrated air pump 10 for inflation and deflation is helping an external device to deflate, the gas will enter the integrated air pump 10 from the air outlet 111, thereby allowing the gas to press the umbrella valve 400 down onto the second shell 120. At this time, the umbrella valve 400 will seal the air inlet hole 122, and thus prevent the gas from entering the rubber bowl 230 from the air inlet hole 122, thereby preventing the gas from flowing back.

[0034] In order to improve the air tightness of the air pump 10 that can be used for charging and discharging, in one embodiment, Figure 3As shown, a movable groove 112 and an air passage 113 are formed on a side of the first shell 110 facing the second shell 120. The umbrella valve 400 is movably disposed in the movable groove 112. The air passage 113 is used to connect the gas outlet 111 and the movable groove 112, and the movable groove 112 is connected to the gas inlet 122. Specifically, when the first shell 110 and the second shell 120 are connected, the movable groove 112 and the air passage 113 will be sealed by the second shell 120. At this time, gas can only flow between the gas outlet 111 and the movable groove 112 through the air passage 113, thereby improving the airtightness of the integrated inflation and deflation air pump 10.

[0035] To better facilitate deflation of the integrated air pump 10, in one embodiment, the second housing 120 includes a protruding air hole block surrounding the first air release hole 121, with the first air release hole 121 formed on the air hole block. Specifically, the air hole block is inserted into the air outlet 111. This arrangement allows the first air release hole 121 to align with the air outlet 111, thereby enabling the integrated air pump 10 to better deflate.

[0036] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
