Description

Technical Field

[0001] The utility model relates to the technical field of air pumps, in particular to a dual-power supply air pump. Background Art

[0002] A dual power air pump is a pump that can be inflated by two different power sources (AC / DC), usually using batteries or DC power for inflation. This type of air pump can be more flexible to adapt to different usage scenarios, such as outdoor camping, car tire inflation, etc.

[0003] In order to be able to adapt to different usage scenarios more flexibly, it is necessary to use a dual-power air pump for operation. For example, the prior art Chinese patent announcement number "CN107269492A" discloses an AC / DC dual-purpose air pump, including a casing, and also including a DC air pump movement and an AC air pump movement arranged upright and side by side in the casing. The DC air pump movement includes a movement shell and a movement mechanism arranged in the movement shell. The movement shell includes a first movement half shell and a second movement half shell that matches the first movement half shell; the joint surface of the first movement half shell and the second movement half shell is perpendicular to the operation panel surface. The present invention arranges the DC air pump movement and the AC air pump movement upright and side by side in the casing, freeing up space in the casing for installing other components such as a pressure gauge, so that the space in the casing is maximized.

[0004] Although some dual-power air pumps can use two power sources for inflation, in actual operation, such dual-power air pumps cannot filter the air inlet on the one hand, and do not have a shock-absorbing function on the other hand. This may easily lead to dust accumulation at the air inlet after a long time due to the lack of dust-proof measures, thus affecting its use. In addition, considering that severe collisions may easily cause damage to the air pump, its practicality is poor. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art that the air inlet cannot be filtered and the air inlet does not have a shock absorbing function, and to propose a dual-power supply air pump.

[0008] Furthermore, a plurality of first buckles are provided on the bottom and sides of the shell, and a bellows is clamped through the first buckles. The input end of the pump assembly is provided with an air inlet communicated with the dust cover, and the output end thereof is provided with an air outlet through the back side of the shell, and one end of the bellows can be connected to the air outlet.

[0009] Furthermore, the clamping part includes a connecting seat fixedly installed on the side of the shell, the side of the connecting seat is located inside the shell and the pump assembly is fixedly installed, and the four sides extend toward the center point to form a mounting groove and a raised edge, the bottom of the dust cover is provided with a recessed portion, and it can be inserted into the mounting groove, and the raised edge can be inserted into the recessed portion.

[0023] Furthermore, a plurality of first buckles 11 are provided at the bottom and sides of the outer shell 1, and a bellows 12 is clamped through the first buckles 11. The input end of the pump assembly 3 is provided with an air inlet 13 communicated with the dust cover 6, and the output end thereof is provided with an air outlet 14 through the back side of the outer shell 1, and one end of the bellows 12 can be connected to the air outlet 14.

[0024] It should be noted that the dust cover 6 is provided with a plurality of ventilation slots, and the dust cover 6 can be connected to the air inlet 13 by means of the ventilation slots, so as to play a role in dust prevention.

[0025] Furthermore, the clamping member 5 includes a connecting seat 51 fixedly installed on the side of the outer shell 1, the side of the connecting seat 51 is located inside the outer shell 1 and the pump assembly 3 is fixedly installed, and the surrounding areas extend toward the center point to form a mounting groove 52 and a raised edge 53, the bottom of the dust cover 6 is provided with a recessed portion 54, and it can be inserted into the mounting groove 52, and the raised edge 53 can be inserted into the recessed portion 54.

[0026] The specific operation is to insert the dust cover 6 into the installation groove 52, and then insert the recessed portion 54 into the raised edge 53, so that the bottom of the dust cover 6 can be fixed.

[0027] In more detail, a second buckle 55 is fixedly installed on the top of the dust cover 6, and a clamping seat 56 is fixedly installed on the side of the connecting seat 51. The clamping seat 56 has a slide groove 57 extending through it and a claw 58 is slidably connected to it through the slide groove 57. A guide rod 59 is fixedly installed in the slide groove 57. The outer periphery of the guide rod 59 is provided with a first spring 591. The claw 58 is slidably connected to the guide rod 59. The two ends of the first spring 591 are respectively fixedly connected to the slide groove 57 and the side of the claw 58, and the claw 58 is clamped with the second buckle 55.

[0028] It is worth mentioning that the guide rod 59 is used to ensure that the claw 58 moves smoothly. Under the support of the first spring 591, the claw 58 and the second buckle 55 can be tightly clamped together to fix the top of the dust cover 6.

[0029] In general, the buffer member 8 includes two groups of support rods 81 fixedly installed on the top of the base 7, the support rods 81 are slidably connected to the bottom of the outer shell 1, and a damping outer cylinder 82 and a damping rod 83 are fixedly installed between the base 7 and the opposite sides of the outer shell 1, respectively. A damping inner cylinder 84 is sleeved in the damping outer cylinder 82, and a cavity 85 exists between the damping outer cylinder 82 and the damping inner cylinder 84, and hydraulic oil is filled in the cavity 85.

[0030] Finally, the top and bottom of the damping inner cylinder 84 are penetrated by through holes 841, the other end of the damping rod 83 is provided with a piston head 86 and is slidably connected to the damping inner cylinder 84, the piston head 86 is tightly fitted with the inner wall of the damping inner cylinder 84, and the outer periphery of the damping outer cylinder 82 is provided with a second spring 87, and the two ends of the second spring 87 are respectively fixedly connected to the side surfaces of the outer shell 1 and the base 7.

[0031] The specific operation is that, because of the provision of the cavity 85, hydraulic oil is poured in to make it a shock-absorbing and buffering medium. When the air pump drives the damping rod 83 to descend, because of the cavity 85 and the through hole 841, the damping rod 83 moves slowly to achieve the effect of buffering and shock-absorbing. Then, the second spring 87 is used to move the damping rod 83 upward. Because the through holes 841 are provided at the top and the bottom, the hydraulic oil refluxes to make the damping rod 83 move slowly.

[0032] Working method: When working, remove the bellows 12 from the first buckle 11 and connect one end to the air outlet 14, so that the object can be inflated;

[0033] Then, when the dust cover 6 needs to be replaced, the claw 58 is pushed to slide and disengage from the second buckle 55, and the top of the dust cover 6 can be tilted to disengage the recessed portion 54 from the raised edge 53, so that the dust cover 6 can be disassembled, and the claw 58 will return to its original position under the action of the first spring 591 and wait for the next clamping and fixing of the dust cover 6;

[0034] Finally, when an unexpected operation or collision occurs, the air pump drives the damping rod 83 to move downward, and because of the through hole 841 and the cavity 85, the damping rod 83 moves slowly to achieve the effect of buffering and shock absorption. Then, under the action of the second spring 87, the damping rod 83 drives the air pump back to its original position, and then because of the through hole 841 and the piston head 86, the hydraulic oil flows back, and the damping rod 83 moves slowly upward.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
