[0030] like Figures 1 to 9 As shown, the present invention provides an internal and external dual-purpose pump for a sponge bed, comprising a housing 1 and a pump body 2 detachably disposed within the housing 1. The pump body 2 comprises a housing 21 and a receiving chamber formed within the housing 21. The housing 21 is provided with an air inlet and outlet 211 and an air pumping and charging port 212. The receiving chamber is provided with a power supply assembly 22 and a suction assembly and a control assembly 23 connected to the power supply assembly 22. The suction assembly comprises a flow channel assembly 24, a push plate 25, and a micro switch 26. When the push plate 25 is pushed left or right, the flow channel assembly 24 is driven to move left or right as a whole and trigger the micro switch 26, thereby starting the inflation or extraction operation. The micro switch 26 is connected to the control assembly 23. When the push plate 25 moves, the micro switch 26 is triggered, thereby starting the air pumping or inflation operation.

[0031] When the pump body 2 is taken out, it can be used as an external pump. When the pump body 2 is installed in the outer shell 1, it can be used as a built-in pump. The outer shell 1 is set inside the sponge bed. If the air pump is damaged, you only need to take out the pump body 2 for maintenance, which is flexible and convenient.

[0032] In other words, the present invention comprises a housing 1 and a pump body 2 detachably disposed within the housing 1. When the pump body 2 and the housing 1 (the housing 1 and the inflatable product are welded together or integrally formed) are assembled together to inflate the sponge bed, a built-in pump structure is formed, which can directly inflate the sponge bed. The pump body 2 can also be removed from the housing 1 and used separately, in which case it acts as an external pump structure, capable of inflating other inflatable products. Furthermore, simply pushing the push plate 25 allows switching between the inflation and deflating functions, providing a very convenient experience.

[0033] The utility model is provided with a large number of air inlets and outlets 211, which has a good heat dissipation effect, and has an independently movable flow channel component 24, which has strong performance, high air pressure and low noise.

[0034] The flow channel assembly 24 includes a flow channel cover 241, a flow channel body 242, a fan blade 243, a motor bracket 244 and a motor 245. The cover 241, the flow channel body 242 and the motor bracket 244 together form a accommodating cavity. The fan blade 243 is arranged in the accommodating cavity. The output end of the motor 245 is connected to the fan blade 243. A first flow channel outlet 2421 and a second flow channel outlet 2422 are formed on one side of the flow channel body 242. When in the inflated state, the first flow channel outlet 2421 is connected to the air suction and charging port 212, and the second flow channel outlet 2422 is connected to the accommodating cavity; when in the exhaust state, the second flow channel outlet 2422 is connected to the air suction and charging port 212, and the first flow channel outlet 2421 is connected to the accommodating cavity. When inflation is required, push the push plate 25 to the left. At this time, the first flow channel outlet 2421 is connected to the air pumping and inflation port 212. At the same time, the push plate 25 triggers the micro switch 26. After receiving the signal, the control component 23 instructs the motor 245 to start moving. The motor 245 rotates with the fan blade 243. The air enters the accommodating cavity from the air inlet and outlet 211, and then enters the accommodating cavity from the second flow channel outlet 2422, and finally enters the sponge bed from the first flow channel outlet 2421 through the air pumping and inflation port 212. When air needs to be extracted, push the push plate 25 to the right. At this time, the second flow channel outlet 2422 is connected to the air extraction and inflation port 212. At the same time, the push plate 25 triggers the micro switch 26. After receiving the signal, the control component 23 instructs the motor 245 to start moving. The motor 245 rotates with the fan blade 243. The air passes through the air extraction and inflation port 212 and the second flow channel outlet 2422 in turn and enters the accommodating cavity, and then enters the accommodating cavity from the first flow channel outlet 2421, and is finally discharged from the air inlet and outlet 211.

[0035] The top of the push plate 25 houses a ball spring 251 and a ball 252. The ball 252 is installed within the ball spring 251 and is squeezed into the top of the push plate 25, locking it in place and providing a spring-loaded travel. A mounting post 254 is formed at the bottom of the push plate 25, and a boss 2424 is provided at the top of the flow channel body 242, which engages with the mounting post 254. Consequently, pushing the push plate 25 moves the flow channel body 242. A push block 253 is also provided at the top of the push plate 25. A limited sliding hole 213 is formed at the top of the housing 21. The push block 253 extends from the limited sliding hole 213, and the limited sliding hole 213 limits the movement of the push block 253.

[0036] The housing 21 includes a cavity 214, a cover 215, and a transparent bottom cover 216. Cavity 214 is located between the cover 215 and the transparent bottom cover 216. The lower surface of the cover 215 is provided with several grooves 2151 for accommodating marbles 252. When the device is off, the marbles 252 are lodged in the grooves 2151. When the push plate 25 is pushed to initiate inflation / deflation, the marbles 252 move with it and latch into the left or right grooves 2151. The marbles 252 are positioned in the grooves 2151, and the left and right grooves 2151 provide a better feel and a more intuitive start-up experience.

[0037] A light board 27 is provided between the cavity 214 and the transparent bottom cover 216, and a micro switch 26 is provided on a switch bracket 28. An air avoidance position is formed on the lower surface of the push plate 25. In the off state, the micro switch 26 is located under the air avoidance position. When the micro switch 26 is pushed left or right, the air avoidance position is moved away, the micro switch 26 is touched, and air is pumped in or out.

[0038] The control assembly 23 includes a PCBA board 231. The housing 21 is provided with a TYPE-C charging port 217, a lighting switch 218 and a charging indicator light 219.

[0039] The front cover 212 is provided with a handle 2122, with buckles at both ends for the handle 2122 to be snapped into the front cover 212. The transparent bottom cover 213 is snap-connected to the bottom of the cavity 211. This product is easy to assemble, has high production efficiency, low assembly cost, and after assembly, the screw positions are invisible, making the product aesthetically pleasing.

[0040] The housing 1 comprises a main body 11, a main body cover 12, an airtight bracket 13, an airtight rubber ring 14, an airtight spring 15, and a dust cover 16. The main body cover 12 is pivotally connected to one side of the main body 11. An inlet 17 is provided at the bottom of the main body 11. The airtight bracket 13 is positioned within the inlet 17, and the dust cover 16 is positioned outside the inlet 17. During assembly, the airtight rubber ring 14 is first fitted over the airtight bracket 13, followed by the airtight spring 15, the airtight bracket 13, the dust cover 16, the screws tightened, and finally the main body cover 12 is mounted on one side of the main body 11. When in use, the main body cover 12 is open.

[0041] The handle 2122 has steps at both ends, and the housing 11 is provided with slots. When installing the pump body 2 into the outer casing 1, first lift the handle 2122 of the pump body 2 90 degrees and insert it, aligning the steps with the slots. After installation, lay the handle 2122 flat, and snap the steps on both sides of the handle 2122 into the slots of the housing 11. Once snapped in, the outer pump is firmly fixed in the housing 11, preventing it from shaking or falling out. To remove the pump body 2, lift the handle 90 degrees and pull it out.

[0042] A recess 2423 is formed between the first flow channel outlet 2421 and the second flow channel outlet 2422. When the pump body 2 is installed in the main body 11, the airtight bracket 13 is inserted into the recess. When the flow channel assembly 24 slides to the left or right, the flow channel assembly 24 pushes open the airtight bracket 13 to inflate or deflat. That is, the airtight bracket needs to be pushed open when inflating, and it also needs to be pushed open when deflating.

[0043] When the built-in pump is used to inflate, the push plate 25 is pushed to the left. At this time, the first flow channel outlet 2421 is connected to the air pumping and inflation port 212, and the flow channel component 24 pushes open the airtight bracket 13. At the same time, the push plate 25 triggers the microswitch 26. After receiving the signal, the control component 23 instructs the motor 245 to start moving. The motor 245 rotates with the fan blade 243, and the air enters the accommodating cavity from the air inlet and outlet 211, and then enters the accommodating cavity from the second flow channel outlet 2422, and finally enters the sponge bed from the first flow channel outlet 2421 through the air pumping and inflation port 212 and the entrance and exit 17. When it is necessary to exhaust air, push the push plate 25 to the right. At this time, the second flow channel outlet 2422 is connected to the air extraction and inflation port 212, and the flow channel component 24 pushes open the airtight bracket 13. At the same time, the push plate 25 triggers the microswitch 26. After receiving the signal, the control component 23 instructs the motor 245 to start moving. The motor 245 rotates with the fan blade 243. The air passes through the inlet and outlet 17, the air extraction and inflation port 212, and the second flow channel outlet 2422 in turn, and then enters the accommodating cavity, and then enters the accommodating cavity from the first flow channel outlet 2421, and is finally discharged from the air inlet and outlet 211.
