Description

Technical Field

[0001] The utility model relates to the technical field of air pumps, in particular to a rotary charging and discharging air pump. Background Art

[0002] An air pump is a device that blows air into a closed space or extracts air from a closed space. The principle of the air pump is that the motor drives the wind wheel to rotate to drive the continuous flow of air pressure.

[0003] With the development of technology, the air pump has evolved from the past single-direction inflation structure to the current two-way charging and discharging. For example, Chinese Patent Document CN221442775U discloses an integrated charging and discharging air pump, which includes an outer cylinder, a one-way valve mechanism provided at the bottom of the outer cylinder, and a suction and discharge air mechanism that can be placed in the outer cylinder in the forward or reverse direction; the outer cylinder is connected to the product to be inflated or deflated; the suction and discharge air mechanism has an air inlet. When the suction and discharge air mechanism is placed forward and the air inlet is close to the product, the one-way valve mechanism seals the bottom of the outer cylinder, and the suction and discharge air mechanism extracts air from the product; when the suction and discharge air mechanism is placed in reverse and the air inlet is close to the one-way valve mechanism, the one-way valve mechanism opens, the outer cylinder communicates with the external atmospheric pressure, and the suction and discharge air mechanism sucks air from the outside and fills it into the product. In this way, when the suction and discharge air mechanism is placed forward in the outer cylinder, the suction and discharge air mechanism can extract air from the product, and when the suction and discharge air mechanism is placed in reverse in the outer cylinder, the suction and discharge air mechanism can inflate the product.

[0004] However, for the existing such air pump to achieve forward air extraction and reverse inflation, it is necessary to reverse the suction and discharge air mechanism, which is not convenient to use. Therefore, in order to simplify the user's usage method and make it more convenient to use, the rotary charging and discharging air pump of the present application is proposed.

Detailed implementation manners

[0039] For the convenience of understanding the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. The preferred embodiments of the present invention are shown in the drawings.

[0040] As Figures 1 to 9 shown, a rotary charging and discharging pump 10 includes a housing 100 and a pump core 200. A housing cavity 110 is formed in the housing 100, and a housing hole 120 is formed in the inner bottom wall of the housing cavity 110. The pump core 200 includes a pump housing 210 and a suction driving member 221. The pump housing 210 is detachably inserted into the housing cavity 110. A pump cavity 211 is formed in the pump housing 210. An air inlet hole 212 and an air outlet hole 213 are formed at one end of the pump housing 210 close to the housing hole 120. The air inlet hole 212 and the air outlet hole 213 are respectively communicated with the pump cavity 211. The suction driving member 221 is arranged in the pump cavity 211. The suction driving member 221 is used to drive gas to enter the pump cavity 211 from the air inlet hole 212 and then flow out from the air outlet hole 213. When the pump core 200 is rotated clockwise in the housing cavity 110 by an external force, one of the air inlet hole 212 and the air outlet hole 213 is communicated with the housing hole 120. When the pump core 200 is rotated counterclockwise in the housing cavity 110 by an external force, the other of the air inlet hole 212 and the air outlet hole 213 is communicated with the housing hole 120. When one of the air inlet hole 212 and the air outlet hole 213 is communicated with the housing hole 120, the other of the air inlet hole 212 and the air outlet hole 213 is communicated with the housing cavity 110.

[0041] It should be noted that a hollow shell cavity 110 is provided inside the outer shell 100, and a shell hole 120 communicating with the shell cavity 110 is provided at the bottom of the shell cavity 110. The pump core 200 is used to be inserted into the shell cavity 110. A pump cavity 211 is provided inside the pump housing 210, and an air inlet hole 212 and an air outlet hole 213 are provided at one end of the pump housing 210 close to the shell hole 120. The air inlet hole 212 and the air outlet hole 213 are respectively communicated with the pump cavity 211. The suction driving member 221 is installed in the pump cavity 211. In one embodiment, the suction driving member 221 is a centrifugal fan. Thus, with the start of the suction driving member 221, after the gas enters the pump cavity 211 from the air inlet hole 212, it then flows out of the pump cavity 211 from the air outlet hole 213. Further, the pump core 200 is inserted into the shell cavity 110, and the pump core 200 can rotate clockwise or counterclockwise in the shell cavity 110, so that the pump core 200 cooperates with the outer shell 100 to form a gas pumping or gas filling function. It should be noted that the clockwise / counterclockwise mentioned in this application refers to the view when looking directly at the inside of the shell cavity 110.

[0042] Specifically, the shell cavity 110 is used to communicate with the outside, and the shell hole 120 is used to communicate with the inflatable product. Embodiment 1:

[0043] When the pump core 200 rotates clockwise, the air outlet hole 213 is communicated with the shell hole 120, and the air inlet hole 212 is communicated with the shell cavity 110. With the start of the suction driving member 221, the air in the shell cavity 110 will flow through the air inlet hole 212, the pump cavity 211, the air outlet hole 213, and the shell hole 120 in sequence, and at this time, the inflatable product is inflated.

[0044] When the pump core 200 rotates counterclockwise, the air inlet hole 212 is communicated with the shell hole 120, and the air outlet hole 213 is communicated with the shell cavity 110. With the start of the suction driving member 221, the air in the inflatable product flows through the shell hole 120, the air inlet hole 212, the pump cavity 211, the air outlet hole 213, and the shell cavity 110 in sequence, and at this time, the gas pumping function for inflation is realized.

[0045] Embodiment 2:

[0046] When the pump core 200 rotates clockwise, the air inlet hole 212 is communicated with the shell hole 120, and the air outlet hole 213 is communicated with the shell cavity 110. With the start of the suction driving member 221, the air in the inflatable product flows through the shell hole 120, the air inlet hole 212, the pump cavity 211, the air outlet hole 213, and the shell cavity 110 in sequence, and at this time, the gas pumping function for inflation is realized.

[0047] When the pump core 200 rotates counterclockwise, the air outlet hole 213 communicates with the housing hole 120, and the air inlet hole 212 communicates with the housing cavity 110. As the suction driving member 221 is activated, the air in the housing cavity 110 will flow through the air inlet hole 212, the pump cavity 211, the air outlet hole 213, and the housing hole 120 in sequence, and at this time, the inflatable product is inflated. In this way, whether the pump core 200 inflates or deflates the product clockwise can be designed according to specific situations.

[0048] To facilitate the description of the principle of the solution of the rotary inflator / deflator pump 10 of the present application, the following content will be described by taking the example of inflating the product when the pump core 200 rotates clockwise.

[0049] As Figure 2 shown, in an embodiment, a clearance groove 130 is further formed on the inner bottom wall of the housing cavity 110, and the clearance groove 130 is used to align with the air outlet hole 213 / air inlet hole 212.

[0050] It should be noted that both the air inlet hole 212 and the air outlet hole 213 protrude relative to the end face of the pump housing 210. When the air inlet hole 212 communicates with the housing hole 120, the air outlet hole 213 aligns with the clearance groove 130. In this way, the air outlet hole 213 can communicate with the housing cavity 110 through the clearance groove 130, so as to ensure that the gas of the product flows through the housing hole 120, the air inlet hole 212, the pump cavity 211, the air outlet hole 213, the clearance groove 130, and the housing cavity 110 in sequence to deflate the product. When the air outlet hole 213 communicates with the housing hole 120, the air inlet hole 212 aligns with the clearance groove 130. In this way, the air inlet hole 212 communicates with the housing cavity 110 through the clearance groove 130, so as to ensure that the product in the housing cavity 110 flows through the clearance groove 130, the air inlet hole 212, the pump cavity 211, the air outlet hole 213, and the housing hole 120 and then flows into the product to inflate the product. In this way, by providing the clearance groove 130, it is ensured that the air inlet hole 212 / air outlet hole 213 communicates with the housing cavity 110 through the clearance groove 130.

[0051] As Figure 10 shown, in an embodiment, a check valve 300 is slidably arranged along the axial direction of the housing hole 120 on the side of the housing hole 120 away from the housing cavity 110, and the air outlet hole 213 or the air inlet hole 212 communicating with the housing hole 120 is used to push the check valve 300 away from the housing hole 120.

[0052] It should be noted that when the pump core 200 does not rotate clockwise / counterclockwise, neither the air inlet hole 212 nor the air outlet hole 213 will communicate with the housing hole 120. At this time, the check valve 300 is closely attached to the side of the housing hole 120 away from the housing cavity 110, so that the check valve 300 seals the housing hole 120, that is, the product is not communicated with the housing hole 120. When the air inlet hole 212 communicates with the housing hole 120, that is, when the product needs to be evacuated, the check valve 300 is pushed away from the housing hole 120 by the air inlet hole 212, so that the product communicates with the housing hole 120, so that the gas in the product flows into the air inlet hole 212 through the housing hole 120, realizing the evacuation of the product. When the air outlet hole 213 communicates with the housing hole 120, that is, when the product needs to be inflated, the check valve 300 is pushed away from the housing hole 120 by the air outlet hole 213, so that the product communicates with the housing hole 120, so that the gas in the air outlet hole 213 flows into the product through the housing hole 120, realizing the inflation of the product. In one embodiment, the check valve 300 is a sealing film, and the sealing film is pushed by a spring to closely fit with the side of the housing hole 120 away from the housing cavity 110.

[0053] As Figure 3 and Figure 4 shown, in one embodiment, an air duct 214 is further provided on the pump housing 210. The air duct 214 extends from one end of the pump housing 210 to the other end, and the air duct 214 is independent of the pump cavity 211.

[0054] It should be noted that the housing cavity 110 is used to communicate with the outside air. Therefore, a groove can be provided on the outer side wall of the pump housing 210 to make the housing cavity 110 communicate with the outside air. Further, as shown in this embodiment, an air duct 214 penetrating both ends of the pump housing 210 can also be provided on the pump housing 210, where the air duct 214 and the pump cavity 211 are independent structures. Thus, when the air outlet hole 213 communicates with the housing hole 120, at this time, it is in the state of inflating the product. As the suction driving member 221 is started, the outside air flows into the housing cavity 110 from the air duct 214, and then sequentially flows through the clearance groove 130, the air inlet hole 212, the pump cavity 211, the air outlet hole 213, the housing hole 120, and finally into the product. When the air inlet hole 212 communicates with the housing hole 120, at this time, it is in the state of evacuating the product. As the suction driving member 221 is started, the air in the product sequentially flows through the housing hole 120, the air inlet hole 212, the pump cavity 211, the air outlet hole 213, the clearance groove 130, the housing cavity 110, the air duct 214, and finally flows to the outside.

[0055] In one embodiment, a plurality of air ducts 214 are provided, and each air duct 214 penetrates both ends of the pump housing 210, and there is a gap between each air duct 214. For example, one, two, three, four, five, etc. air ducts 214 are provided. In this way, the air flow rate can be increased.

[0056] AsFigures 1 to 3 As shown, in one embodiment, a clamping convex portion 231 is slidably arranged on the outer side wall of the pump housing 210 along the radial direction of the pump housing 210, a sliding groove 111 is formed on the inner side wall of the housing cavity 110, and the clamping convex portion 231 is slidably arranged in the sliding groove 111.

[0057] It should be noted that in order to enable the pump core 200 to stably rotate clockwise / counterclockwise in the housing cavity 110, a sliding groove 111 is formed on the inner side wall of the housing cavity 110, and then a clamping convex portion 231 is arranged on the outer side wall of the pump housing 210, so that the clamping convex portion 231 slides along the sliding groove 111.

[0058] As Figure 1 and Figure 11 shown, in one embodiment, the middle part of the sliding groove 111 is obliquely distributed along the direction close to the housing hole 120 from the middle part of the sliding groove 111 to both ends.

[0059] It should be noted that the middle part of the sliding groove 111 is in an inclined state from the middle part to both ends, and is inclined along the direction close to the housing hole 120. Thus, when the clamping convex portion 231 is located in the middle part of the sliding groove 111, the suction driving member 221 is in a stopped state at this time. When the pump core 200 rotates clockwise in the housing cavity 110, the clamping convex portion 231 slides from the middle part to one end along the sliding groove 111. Thus, due to the structure that the middle part of the sliding groove 111 is inclined close to the housing hole 120 from the middle part to both ends, the pump core 200 will slide axially relative to the housing cavity 110 by a certain distance. When the clamping convex portion 231 reaches the end of one end of the sliding groove 111, the air outlet hole 213 of the pump housing 210 is docked with the housing hole 120, so that the air outlet hole 213 is reliably communicated with the housing hole 120. At this time, the suction driving member 221 is started, and the product can be inflated. Similarly, when the pump core 200 rotates counterclockwise in the housing cavity 110, the clamping convex portion 231 slides from the middle part to the other end along the sliding groove 111. Thus, due to the structure that the middle part of the sliding groove 111 is inclined close to the housing hole 120 from the middle part to both ends, the pump core 200 will also slide axially relative to the housing cavity 110 by a certain distance. When the clamping convex portion 231 reaches the end of the other end of the sliding groove 111, the air inlet hole 212 of the pump housing 210 is docked with the housing hole 120, so that the air inlet hole 212 is reliably communicated with the housing hole 120. At this time, the suction driving member 221 is started, and the product can be evacuated.

[0060] As Figure 2 、 Figure 3 and Figure 12 shown, in one embodiment, a top column 410 is arranged on the inner bottom wall of the housing cavity 110, a slot 215 is formed at one end of the pump housing 210 close to the air outlet hole 213, a plug slider 420 is slidably arranged in the slot 215, and a top spring 430 is arranged at one end of the plug slider 420 away from the top column 410. The top spring 430 is used to push the plug slider 420 to abut against the top column 410.

[0061] It should be noted that when the convex portion 231 is located within the sliding groove 111, the pump core 200 is completely received within the housing cavity 110. To facilitate the removal of the pump core 200, a top post 410 is provided on the inner bottom wall of the housing cavity 110. The top post 410 is located at the central position of the pump core 200. Correspondingly, the slot 215 is also located at the axial center position of the pump housing 210. A plug slider 420 pushed by a spring is slidably installed within the slot 215. One end of the top post 410 extends into the slot 215, causing the plug slider 420 to abut against the top post 410. In this way, when the convex portion 231 retracts into the pump housing 210, the spring will push the plug slider 420 to slide within the slot 215. Since the plug slider 420 abuts against the top post 410, the pump core 200 is withdrawn from the housing cavity 110.

[0062] As Figure 1 and Figure 13 shown, in one embodiment, the pump core 200 further includes a support block 232, a pressing block 233, a side slider 234, and a side sliding spring 235. The support block 232 is disposed within the pump housing 210. The pressing block 233 is slidably disposed along the axial direction of the pump housing 210 at the top of the pump housing 210. The side slider 234 is slidably disposed on the support block 232, and the side slider 234 is connected to the pressing block 233. The side sliding spring 235 is sleeved on the side slider 234, and the side sliding spring 235 abuts against the side slider 234 and the support block 232 respectively. The convex portion 231 is disposed on the side slider 234. When the pressing block 233 is subjected to pressure, the pressing block 233 pushes the side slider 234 to slide, causing the side slider 234 to compress the side sliding spring 235 and the convex portion 231 to retract into the pump housing 210.

[0063] It should be noted that the support block 232 is installed in the pump housing 210 by screws. The pressing block 233 is slidably installed along the axial direction of the pump housing 210 at the end far from the air inlet hole 212, and a part of the structure of the pressing block 233 protrudes from the top surface of the pump housing 210. The side slider 234 is slidably installed along the radial direction of the pump housing 210 on the support block 232, and the convex portion 231 is located at the end of the side slider 234 far from the pressing block 233. The side sliding spring 235 is sleeved on the side slider 234, and the side sliding spring 235 abuts against the side slider 234 and the support block 232 respectively. In this way, under the elastic thrust of the side sliding spring 235, the convex portion 231 has a tendency to protrude from the outer wall of the pump housing 210 in the natural state, so that the convex portion 231 is engaged in the sliding groove 111. When the pressing block 233 is subjected to a pressing force, the pressing block 233 drives the side slider 234 to slide along the radial direction of the pump housing 210. The side slider 234 compresses the side sliding spring 235, and the convex portion 231 retracts into the pump housing 210. In this way, under the pushing action of the top holding spring 430, the pump core 200 will pop out from the housing cavity 110. When the external force on the pressing block 233 is removed, the side sliding spring 235 pushes the side slider 234, so that the convex portion 231 protrudes from the outer wall of the pump housing 210 again.

[0064] As Figure 2 , Figure 13 and Figure 14 shown, in an embodiment, the pump core 200 further includes a circuit board 222 and a sliding column 223. The circuit board 222 is disposed in the pump housing 210, and the circuit board 222 is electrically connected to the suction driving member 221. A switch 224 is disposed on the circuit board 222. The sliding column 223 is slidably disposed along the axial direction of the pump housing 210 in the pump housing 210, and one end of the sliding column 223 is in contact with the switch 224, and the other end of the sliding column 223 protrudes from the end of the pump housing 210 close to the air outlet hole 213. Two top blocks 510 are disposed on the inner bottom wall of the housing cavity 110. When the pump core 200 is rotated clockwise / counterclockwise by an external force, one of the two top blocks 510 pushes the sliding column 223.

[0065] It should be noted that the circuit board 222 is installed on the inner side wall of the pump housing 210 by screws. A guiding groove for the sliding of the sliding column 223 is also provided in the pump housing 210, so that the sliding column 223 can slide along the axial direction of the pump housing 210. A switch 224 is installed on the circuit board 222. One end of the sliding column 223 is in contact with the switch 224. In the natural state, there is only a contact state between the sliding column 223 and the switch 224, without any acting force. The other end of the sliding column 223 extends from the end face of the pump housing 210 close to the air outlet hole 213. Two top blocks 510 are provided on the inner bottom wall of the housing cavity 110. Thus, when the pump core 200 rotates clockwise / counterclockwise in the housing cavity 110, due to the inclined state of the sliding groove 111, the convex part 231 slides along the sliding groove 111. While the pump core 200 rotates, it will slide axially relative to the pump housing 210 by a certain distance. That is, as the pump core 200 rotates, the pump core 200 will drive the sliding column 223 to abut against one of the two top blocks 510. Thus, the sliding column 223 is pushed by the top block 510. At this time, the sliding column 223 will press the switch 224, so that the suction driving member 221 is started. Thus, by rotating the pump core 200, the suction driving member 221 can be started and stopped simultaneously, without the need to press and start separately, so it is more convenient to use.

[0066] As Figure 13 shown, in one embodiment, a first inclined surface 2331 is provided on the pressing block 233, and the side slider 234 abuts against the first inclined surface 2331.

[0067] It should be noted that when the pressing block 233 is subjected to a pressing force, the first inclined surface 2331 pushes the side slider 234 to slide along the radial direction of the pump housing 210, so that the convex part 231 retracts into the pump housing 210. When the pressing force on the pressing block 233 is eliminated, the side sliding spring 235 pushes the side slider 234 to slide in the reverse direction, so that the side slider 234 pushes the first inclined surface 2331, and the convex part 231 projects from the outer side wall of the pump housing 210 again. At the same time, the pressing block 233 also projects from the top of the pump housing 210.

[0068] In one embodiment, two convex parts 231 are provided, two sliding grooves 111 are provided, two side sliders 234 are provided, and two first inclined surfaces 2331 are provided. The two side sliders 234 respectively abut against the two first inclined surfaces 2331. The two convex parts 231 are respectively arranged at one ends of the two side sliders 234 away from the first inclined surfaces 2331. The two sliding grooves 111 are symmetrically distributed in a circumferential manner with respect to the axis of the pump housing 210. The two convex parts 231 are respectively located in the two sliding grooves 111. Thus, it can ensure that the pump core 200 is stably inserted into the housing cavity 110.

[0069] As Figure 11 shown, in one embodiment, clamping planes 112 are provided at both ends of the sliding groove 111.

[0070] It should be noted that clamping planes 112 are provided at both ends of the sliding groove 111. In this way, when the pump core 200 rotates clockwise / counterclockwise to the end position of the sliding groove 111, the clamping convex portion 231 will be located on the clamping plane 112. Since the clamping plane 112 is a planar structure and the clamping plane 112 is parallel to the radial plane of the pump housing 210, the clamping convex portion 231 will be stably held on the clamping plane 112 and will not be pushed by the biasing spring 430 to return from the end of the sliding groove 111 along the inclined sliding groove 111 to the middle. At this time, the air pump can inflate or deflate stably. When the air pump finishes inflating / deflating the product, only a certain torque needs to be applied to the pump core 200 to make the clamping convex portion 231 disengage from the clamping plane 112. Under the elastic thrust of the biasing spring 430, the clamping convex portion 231 slides back to the middle of the sliding groove 111 along the inclined sliding groove 111. At this time, the pump core 200 is reset, the air inlet hole 212 and the air outlet hole 213 are both away from the housing hole 120, and the sliding column 223 is also away from the top block 510, causing the suction driving member 221 to stop.

[0071] In one embodiment, a sealing ring is provided on the side of the housing hole 120 close to the housing cavity 110.

[0072] In this way, when the pump core 200 rotates and approaches the housing hole 120, the air inlet hole 212 / the air outlet hole 213 is in close contact with the sealing ring, so that the air inlet hole 212 / the air outlet hole 213 is in close communication with the housing hole 120.

[0073] The above embodiments only represent several implementation manners of the present utility model, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. The installation / fixing / setting mentioned in the present utility model can be understood as including but not limited to locking and fixing using screws / screws and welding unless otherwise specifically defined. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
