Description

[Technical Field]

[0001] This utility model relates to the field of electric air pump technology, and in particular to the design of an air pump that can be used for both inflation and deflation. [Background Technology]

[0002] Inflatable products (including inflatable beds, inflatable pools, inflatable boats, inflatable toys, etc.) are increasingly popular due to their lightweight, small size, and portability. To quickly inflate these products, an air pump is essential. Similarly, larger inflatable products often use an air pump for rapid deflating. However, some existing air pump designs are integrated into the inflatable product, offering only inflation functionality. Others combine inflation and deflating functions, but the inflation and deflating ports are typically located on the same end face. Inflation or deflating is achieved by rotating the pump body relative to the external structure, connecting the inflation or deflating port to the product's outlet. Therefore, with larger inflatable products, users often cannot quickly determine whether the pump is in the inflation or deflating state, making identification and use difficult.

[0027] The technical solutions in the embodiments of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.

[0028] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indication will also change accordingly. Furthermore, descriptions involving "preferred," "second-best," etc., in this utility model are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined as "preferred" or "second-best" may explicitly or implicitly include at least one of those features.

[0029] like Figure 1-8 As shown, a dual-purpose air pump for inflation and deflation includes a pump body 1 and a housing 2 that can be fixed to an inflatable product. The pump body 1 is cylindrical, and the upper end of the housing 2 is provided with an edge that can be welded to the inflatable product.

[0030] The pump body 1 has an air outlet 11 and an air inlet 12 on its upper and lower end faces, respectively. The outer casing 2 has a receiving cavity 21 with a top opening, and a vent 22 at the bottom of the outer casing 2. Both ends of the pump body 1 can be inserted into the receiving cavity 21 to connect the air outlet 11 with the vent 22 or to connect the air inlet 12 with the vent 22. During inflation... Figure 8 As shown, the upper end of the pump body 1 is inserted into the receiving cavity 21 of the outer casing 2. At this time, the air outlet 11 of the pump body 1 is connected to the air vent 22 of the outer casing 2. When the pump body 1 is working, outside air enters the pump body 1 from the air inlet 12 and is discharged from the air outlet 11 into the inflatable product to achieve inflation; when evacuating air, as... Figure 1 As shown, the lower end of the pump body 1 is inserted into the receiving cavity 21 of the outer shell 2. At this time, the air inlet 12 of the pump body 1 is connected to the air outlet 22 of the outer shell 2. When the pump body 1 is working, the air in the inflated product enters the pump body 1 from the air inlet 12 and is discharged to the outside from the air outlet 11 to achieve air extraction.

[0031] The pump body 1 can rotate within the accommodating cavity 21. After the pump body 1 is inserted into the accommodating cavity 21, the upper end of the pump body 1 protrudes from the upper surface of the outer casing 2. A power switch 4 is provided on the lower surface of the pump body 1. Inside the outer casing 2, a switch trigger 23 is provided, which turns on the power switch 4 by rotating the pump body 1 to the trigger position after the pump body 1 is inserted into the accommodating cavity 21 at the lower end. Figure 1-3 and Figure 7As shown, after the lower end of the pump body 1 is inserted into the receiving cavity 21 of the outer shell 2, the power switch 4 located on the lower end face of the pump body 1 cooperates with the switch trigger 23 located on the receiving cavity 21 of the outer shell 2. Pressing the power switch 4 by the switch trigger 23 causes the pump body 1 to work continuously to pump air. In this case, after the receiving cavity 21 of the outer shell 2 is inserted into the lower end of the pump body 1, the pump body 1 and the outer shell 2 can be rotated by rotating the protruding part of the pump body 1 that protrudes from the outer shell 2, thereby rotating the power switch 4 of the pump body 1 to the trigger position where the switch trigger 23 is located, so that the power switch 4 is pressed and triggered. After the receiving cavity 21 of the outer shell 2 is inserted into the upper end of the pump body 1, the power switch 4 is exposed on the protruding part of the pump body 1, and inflation can be achieved by pressing the power switch 4, which facilitates the adjustment of the inflation volume of the inflatable product.

[0032] A fastening assembly is provided between the outer casing 2 and the pump body 1 so that the pump body 1 is fastened in the receiving cavity 21. After the pump body 1 is inserted into the receiving cavity 21 of the outer casing 2, the pump body 1 is securely installed on the outer casing 2.

[0033] like Figure 1-4 and Figure 7 As shown, the fastening assembly includes multiple housing buckles 31 located on the inner bottom surface of the housing 2 near the vent 22 and extending inward. The upper and lower end faces of the pump body 1 are respectively provided with annular pump body surrounds 32 surrounding the vent 11 and vent 12 and extending outward. The outer side of the annular pump body surround 32 has a groove 33 that engages with the housing buckles 31. After the upper or lower end of the pump body 1 is inserted into the receiving cavity 21 of the housing 2, the groove 33 on the annular pump body surround 32 engages with the housing buckles 31 inside the housing 2, locking the pump body 1 onto the housing 2. To unlock, the pump body 1 can be pulled out of the receiving cavity 21 of the housing 2 through the protrusion of the pump body 1 protruding from the housing 2.

[0034] like Figure 1-4 and Figure 7 As shown, the outer shell buckles 31 are evenly arranged around the vent 22 to improve the uniformity of locking and fastening; the inner bottom surface of the outer shell 2 is provided with an arc-shaped inwardly extending positioning protrusion 34 between the two outer shell buckles 31 to improve the fastening stability; the inner bottom surface of the outer shell 2 is provided with an outer shell annular surrounding plate 35 that surrounds the vent 22 and extends inward between the outer shell buckles 31 and the vent 22. The outer shell buckles 31, the positioning protrusion 34 and the outer shell annular surrounding plate 35 form a slot for the pump body annular surrounding plate 32 to be inserted, so that the pump body annular surrounding plate 32 of the pump body 1 can be quickly positioned and inserted into the slot, realizing the quick positioning and fastening of the slot 33 of the pump body annular surrounding plate 32 and the outer shell buckles 31 of the outer shell 2.

[0035] like Figure 3-5 and Figure 7As shown, the bottom of the outer casing 2 is provided with a limiting bracket 24 located inside the vent 22. The limiting bracket 24 is provided with a limiting sliding hole 25. The bottom of the outer casing 2 is provided with a valve core 5 that can slide within the limiting sliding hole 25 and close the vent 22. The lower end face of the pump body 1 is provided with a pushing member 13 located inside the air inlet 12. After the receiving cavity 21 is inserted into the lower end of the pump body 1, the valve core 5 is pushed outward to connect the air inlet 12 with the vent 22. During inflation connection, the air discharged from the air outlet 11 of the pump body 1 pushes the valve core 5 to open, connecting the air outlet 11 with the vent 22 to inflate the inflatable product. After the inflatable product is inflated, the air pressure inside the inflatable product pushes the valve core 5 to close the vent 22 of the outer casing 2. During deflation connection, the pushing member 12 on the air inlet 12 pushes the valve core 5 to open, connecting the air inlet 12 with the vent 22, allowing the inflatable product to deflate.

[0036] like Figure 3-5 and Figure 7 As shown, the valve core 5 includes a connecting frame 51 disposed on the lower end face of the vent 22. A closing block 52 is connected to the lower end of the connecting frame 51 to close the vent 22. A sliding rod 53 is connected to the upper end of the connecting frame 51, passing through a limiting sliding hole 25 and contacting the pushing member 13 at its upper end, and can slide within the limiting sliding hole 25. A limiting boss 54, with its outer side extending outwards, is provided at the upper end of the sliding rod 53 to prevent it from disengaging from the limiting sliding hole 25. During the air extraction connection, the pushing member 12 on the air inlet 12 pushes the limiting boss 54 inwards, causing the sliding rod 53 to slide inwards on the limiting sliding hole 25 of the limiting bracket 24, thereby causing the closing block 52 to move inwards and open the vent 22.

[0037] like Figure 3-5 and Figure 7 As shown, the connecting frame 51 has a connecting frame through hole 55 in the middle. The upper end face of the connecting frame 51 has connecting frame protrusions 56 extending upward on both sides and sliding rod connecting slots 57 set between the sides of the two connecting frame protrusions 56. The lower end face of the limiting boss 54 has a sliding rod connecting boss 58 extending downward. The lower end face of the sliding rod connecting boss 58 has sliding rod connecting buckles 59 that cooperate with the sliding rod connecting slots 57 on both sides. The connecting frame protrusions 56, sliding rod connecting buckles 59 and sliding rod connecting boss 58 form a sliding rod 53. The upper end face of the closing block 52 has a blocking connecting rod 510 that passes through the connecting frame through hole 55. The upper outer side of the blocking connecting rod 510 has a connecting rod limiting protrusion 511 that cooperates with the connecting frame through hole 55 to prevent the blocking connecting rod 510 from disengaging from the connecting frame through hole 55. The structure is simple and easy to assemble. The closing block 52 and the block connecting rod 510 are made of flexible materials such as rubber; the limiting sliding hole 25 is a square sliding hole, and the sliding rod 53 is a square sliding rod that cooperates with the square sliding hole, which can prevent the sliding rod 53 and the limiting sliding hole 25 from rotating relative to each other.

[0038] like Figure 6-7As shown, the bottom of the outer casing 2 is provided with a protective frame 26 located outside the valve core 5. The pusher 13 includes two push rods 131 that are laterally spaced within the vent 22. During the air extraction connection, the two push rods 131 on the air inlet 12 can accurately push the limiting boss 54 inward to move inward, causing the closing block 52 to move inward and open the vent 22.

[0039] like Figure 3-4 and Figure 6-7 As shown, the power switch 4 includes a micro switch 41 disposed inside the pump body 1 with its pressing end facing downwards, and a button linkage 42 that can slide inside the pump body 1, with its upper end in contact with the pressing end of the micro switch 41 and its lower end extending out of the lower end face of the pump body 1. The switch trigger element 23 is a switch trigger protrusion disposed on the inner bottom surface of the housing 2 and protruding upwards. The switch trigger protrusion has a guide slope 231 that guides the button linkage 42 to press the pressing end of the micro switch 41 when the pump body 1 rotates relative to the housing 2. The end of the button linkage 42 extending out of the pump body 1 is an arc surface. After the pump body 1 is connected for pumping, the pump body 1 is rotated so that the pump body 1 and the housing 2 rotate relative to each other. When the power switch 4 of the pump body 1 is rotated to the trigger position where the switch trigger element 23 is disposed, the guide slope 231 of the switch trigger protrusion guides the pressing button linkage 42, thereby pressing the micro switch 41 and making the pump body 1 work.

[0040] like Figure 6-7 As shown, the pump body 1 includes a pump housing 14. Inside the pump housing 14 is an air duct 15 connecting the air inlet 12 and the air outlet 11. Between the air inlet 12 and the air outlet 11, the air duct 15 contains a circuit board 16, a motor 17, and an impeller 18 arranged sequentially. The circuit board 16 is electrically connected to the motor 17 and the microswitch 41 of the power switch 4. The motor 17 shaft is connected to the impeller 18. A rechargeable battery 19, electrically connected to the circuit board 16, is located inside the pump housing 14. A charging interface 110, electrically connected to the circuit board 16, is located on the outer side of the pump housing 14. When the microswitch 41 of the power switch 4 is pressed, the circuit board 16 controls the motor 17 to drive the impeller 18 to rotate. At this time, air enters the air duct 15 from the air inlet 12 and exits from the air outlet 11. During operation, the rechargeable battery 19 supplies power to the circuit board 16 and the motor 17, and can also be charged through the charging interface 110.

[0041] like Figure 9-10 As shown, it also includes connecting nozzles 6 of different diameters that can be connected to inflatable products. The air outlet 11 and air inlet 12 of the pump body 1 can be connected to the connecting nozzles 6 respectively. Similarly, when inflating, the air inlet 12 of the pump body 1 is connected to the connecting nozzle 6 to achieve inflation when the pump body 1 is working; when deflating, the air outlet 11 of the pump body 1 is connected to the connecting nozzle 6 to achieve deflating when the pump body 1 is working.

[0042] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
