Description

Technical Field

[0001] The utility model relates to the technical field of air pumps, in particular to an axial flow charging and discharging air pump. Background Technique

[0002] An air pump generally refers to a tool for inflating inflatable products such as inflatable boats and inflatable mattresses.

[0003] With the development of technology, air pumps have evolved from having only an inflation function in the past to now having both inflation and deflation functions, which can not only improve the inflation efficiency but also the deflation efficiency.

[0004] Existing air pumps all have an air inlet hole communicating with the outside and an air outlet hole communicating with the inflatable product. To ensure that the air pump has sufficient airtightness and prevent air leakage when the air pump stops, a valve is installed at the position of the air outlet hole. During inflation, the valve is pushed open by air pressure, and during deflation, the valve is pushed open by a set valve opening structure.

[0005] Since the opening of the air pump valve and the start of the air pump are two different actions, existing air pumps set the above two parts as independent structures, which means that users need to separately control the opening and closing of the valve and the start and stop of the air pump during use. Due to the excessive number of structures that users need to adjust, the air pump is inconvenient to use. Therefore, an axial flow charging and discharging air pump with linkage control of the start and stop of the air pump and the opening and closing of the valve is proposed in this application. Content of the Utility Model

[0033] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings. The preferred embodiments of the present utility model are shown in the drawings.

[0034] As Figures 1 to 5 shown, an axial flow charging and discharging pump 10 includes a pump housing 100, a fan 200 and an adjusting assembly 300. The pump housing 100 is provided with a first air hole 110 and a second air hole 120 that communicate with each other. The fan 200 is arranged inside the pump housing 100, and the fan 200 is located between the first air hole 110 and the second air hole 120. The adjusting assembly 300 includes a rotary base 310, a pump valve 320, a circuit board 330 and two adjusting switches 340. The pump valve 320 is slidably arranged on the second air hole 120. The rotary base 310 is rotatably arranged inside the pump housing 100, and one end of the rotary base 310 is connected to the pump valve 320. The other end of the rotary base 310 extends to the outer side wall of the pump housing 100. A protrusion 350 is arranged on the outer side wall of the rotary base 310. The circuit board 330 is arranged inside the pump housing 100, and the circuit board 330 is electrically connected to the fan 200. The two adjusting switches 340 are both arranged on the circuit board 330, and the two adjusting switches 340 are distributed around the outside of the rotary base 310. When the rotary base 310 is forced to rotate, the rotary base 310 drives the pump valve 320 away from the second air hole 120, and the protrusion 350 presses one of the adjusting switches 340.

[0035] It should be noted that the pump housing 100 is provided with a first air hole 110 and a second air hole 120 that communicate with each other. The blower 200 is installed inside the pump housing 100. For example, the blower 200 is a high-speed brushless vacuum blower. In this way, by instructing the blower 200 to rotate forward or backward, the air pump realizes the inflation and deflation functions. When inflating, the gas enters the pump housing 100 from the first air hole 110 and then flows out from the second air hole 120. When deflating, the gas enters the pump housing 100 from the second air hole 120 and then flows out from the first air hole 110. Further, the pump valve 320 is slidably installed along the center of the second air hole 120 on the inner side wall of the second air hole 120, and the pump valve 320 is used to seal the second air hole 120. The rotating seat 310 is rotatably installed inside the pump housing 100, and one end of the rotating seat 310 is connected to the pump valve 320, and the other end of the rotating seat 310 extends to the side surface of the pump housing 100 close to the first air hole 110. The circuit board 330 is installed inside the pump housing 100, and two adjustment switches 340 are both installed on the circuit board 330, and the two adjustment switches 340 are distributed around the outer circumference of the rotating seat 310. A convex portion 350 is provided on the outer side wall of the rotating seat 310 at a position close to the adjustment switch 340. In this way, when the user rotates one end of the rotating seat 310, the rotating seat 310 will push the pump valve 320 away from the second air hole 120 to open the second air hole 120. At the same time, the convex portion 350 will push one of the two adjustment switches 340. For example, when the convex portion 350 rotates clockwise in the starting state, it presses the first adjustment switch 340, and when it rotates counterclockwise in the starting state, it presses the second adjustment switch 340. The two adjustment switches 340 are used to control the forward rotation and reverse rotation of the blower 200 respectively. In this way, by rotating the rotating seat 310, the pump valve 320 can be opened and the blower 200 can be started at the same time, with a simple structure and convenient for the user to operate.

[0036] As Figure 2 and Figure 3 shown, in one embodiment, a partition 400 is provided inside the pump housing 100. The blower 200 is disposed on the partition 400, the rotating seat 310 is rotatably disposed on the partition 400, and the circuit board 330 is disposed on the partition 400. In this way, the partition 400 can separate the first air hole 110 and the second air hole 120, and at the same time facilitate the installation of the blower 200, the rotating seat 310 and the circuit board 330.

[0037] As Figure 4 shown, in one embodiment, the rotating seat 310 includes a rotating cylinder 311, an intermediate connecting sleeve 312 and a knob 313. The rotating cylinder 311 is rotatably disposed on the partition 400. The intermediate connecting sleeve 312 is clamped to one end of the rotating cylinder 311. The knob 313 is rotatably disposed on the side surface of the pump housing 100 close to the first air hole 110, and the knob 313 is clamped to the intermediate connecting sleeve 312. The convex portion 350 is located on the outer side wall of the intermediate connecting sleeve 312.

[0038] It should be noted that the rotary drum 311 is rotatably installed on the partition plate 400, and one end of the rotary drum 311 is connected to the pump valve 320. The middle connecting sleeve 312 is used for clamping with the rotary drum 311, and the convex portion 350 is located on the outer side wall of the middle connecting sleeve 312. The knob 313 is rotatably installed on one side surface of the pump housing 100 close to the first air hole 110, and the knob 313 is clamped with the middle connecting sleeve 312. Thus, by rotating the knob 313, the rotary drum 311 and the middle connecting sleeve 312 can be driven to rotate. It should be noted that after the rotary drum 311 passes through the partition plate 400 from the lower side of the partition plate 400, the middle connecting sleeve 312 is locked and fixed on the rotary drum 311 through fasteners. Thus, the integral structure formed by the rotary drum 311 and the middle connecting sleeve 312 can rotate stably relative to the partition plate 400.

[0039] As Figure 2 shown, in one embodiment, a rotary hole 410 is formed in the partition plate 400, and the rotary drum 311 is rotatably arranged in the rotary hole 410. Thus, it is ensured that the rotary drum 311 can rotate stably relative to the partition plate 400.

[0040] As Figure 2 shown, in one embodiment, an air hole 420 is further formed in the partition plate 400, and the blower 200 is arranged in the air hole 420.

[0041] It should be noted that the partition plate 400 divides the inside of the pump housing 100 into two relatively independent cavities, and the two cavities are communicated through the air hole 420, and the blower 200 is installed in the air hole 420. Thus, by controlling the forward or reverse rotation of the blower 200, the gas can be controlled to flow back and forth between the two cavities to realize inflation or deflation.

[0042] As Figure 3 shown, in one embodiment, a first clamping post 314 is arranged on one of the knob 313 and the middle connecting sleeve 312, and a first clamping groove is formed on the other, and the first clamping post 314 is adaptively inserted into the first clamping groove.

[0043] It should be noted that the first clamping post 314 has a four-sided column structure, and correspondingly, the first clamping groove has a four-sided groove structure. Thus, the first clamping post 314 is adaptively inserted into the first clamping groove, so that the knob 313 and the middle connecting sleeve 312 are clamped and installed, that is, the knob 313 can stably drive the middle connecting sleeve 312 to rotate. Further, in one embodiment, a second clamping post is arranged on one of the middle connecting sleeve 312 and the rotary drum 311, and a second clamping groove is formed on the other, and the second clamping post is adaptively inserted into the second clamping groove. Thus, the middle connecting sleeve 312 and the rotary drum 311 are clamped and fixed. Thus, it is ensured that the knob 313 can stably drive the middle connecting sleeve 312 and the rotary drum 311 to rotate.

[0044] As Figure 4As shown, in one embodiment, an arc-shaped groove 3111 is formed at one end of the rotary drum 311 away from the middle joint sleeve 312, and the arc-shaped groove 3111 is used to avoid the pump valve 320.

[0045] It should be noted that as the rotary drum 311 rotates, when the arc-shaped groove 3111 aligns with the pump valve 320, the arc-shaped groove 3111 no longer pushes against the pump valve 320, so the pump valve 320 remains in the state of sealing the second air hole 120. When the arc-shaped groove 3111 does not align with the pump valve 320, the rotary drum 311 will push against the pump valve 320, so that the pump valve 320 moves away from the second air hole 120, that is, the second air hole 120 is in an open state.

[0046] As Figure 5 and Figure 6 shown, in one embodiment, the pump valve 320 includes a pressure plate 321, a valve plate 322 and an elastic member 323. A slide carriage 130 is arranged on the inner side wall of the second air hole 120. The pressure plate 321 is slidably arranged on the slide carriage 130. The valve plate 322 is arranged on one side of the pressure plate 321 close to the second air hole 120. The elastic member 323 is respectively in contact with the slide carriage 130 and the pressure plate 321. The elastic member 323 is used to push against the pressure plate 321 so that the pressure plate 321 drives the valve plate 322 to seal the second air hole 120.

[0047] It should be noted that the slide carriage 130 is installed on the inner side wall of the second air hole 120. The slide carriage 130 is a hollow structure, and a slide hole is formed in the slide carriage 130. The pressure plate 321 is slidably installed in the slide hole. The valve plate 322 is installed on the pressure plate 321. The two ends of the elastic member 323 are respectively in contact with the pressure plate 321 and the slide carriage 130. In this way, under the elastic thrust of the elastic member 323, the pressure plate 321 drives the valve plate 322 to abut against the opening position of the second air hole 120, so that the pressure plate 321 and the valve plate 322 jointly seal the second air hole 120.

[0048] As Figure 2 、 Figure 5 and Figure 7 shown, in one embodiment, an independent air cavity 140 and a material placement cavity 150 are formed in the pump housing 100. A partition plate 400 is located in the air cavity 140. The material placement cavity 150 is used to accommodate wires or a battery box 510.

[0049] It should be noted that the air pump needs to be powered. For example, wires can be led out from the circuit board 330 to connect to an external power supply for power supply, or a battery can be inserted for power supply. Therefore, in order to facilitate the accommodation of wires or a battery, an independent air cavity 140 and a material placement cavity 150 are formed in the pump housing 100. The partition plate 400 is installed on the inner side wall of the air cavity 140. Wires or a battery can be accommodated in the material placement cavity 150.

[0050] As Figure 7As shown, in one embodiment, when the material placement cavity 150 is used to accommodate the battery case 510, the battery case 510 is detachably inserted into the material placement cavity 150. Among them, conductive contacts 520 are provided on the inner side wall of the material placement cavity 150. Correspondingly, metal contacts are provided on the outer side wall of the battery case 510. In this way, when the battery case 510 is inserted into the material placement cavity 150, the metal contacts come into contact with the conductive contacts 520, enabling the battery case 510 to supply power to the circuit board 330.

[0051] As Figure 1 As shown, in one embodiment, a flip cover 600 is rotatably provided on the pump housing 100, and the flip cover 600 is used to shield the material placement cavity 150. In this way, the flip cover 600 is used to cover and protect the wires located in the material placement cavity 150.

[0052] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. Among them, the installation / fixing / setting mentioned in the present invention 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 invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
