Description

Technical Field

[0001] The present application relates to the field of object inflation technology, and in particular to an inflation pump. Background Art

[0002] An air pump is a device used to inflate car tires, bicycle tires, rubber boats, inflatable beds, air cushions, etc. It compresses the gas into high-pressure gas by driving the compressor through an electric motor, thereby achieving the function of inflation.

[0003] In the related technology, the electric air pump compresses the gas into high-pressure gas by driving the compressor through an electric motor. It usually includes pressure sensors, microprocessors, low-noise motors, chargers and other parts. When the air cushion or gas container needs to be inflated, the pressure sensor of the air pump will automatically sense the current gas pressure and feed it back to the microprocessor. Under the control of the microprocessor, the low-noise motor starts working, compressing the gas and sending it into the air cushion or container. During the inflation process, the pressure sensor of the air pump will continuously monitor the changes in gas pressure. Once the pressure reaches the set value, the air pump will automatically stop working to prevent the risk of gas explosion.

[0004] The prior art has the following problems: a button for the operator to adjust the gear position is provided on the air pump, and if the button is hit during the movement of the air pump, the button touch may be damaged, and in severe cases, the button may fail to work, so there is still room for improvement. Utility Model Content

[0005] In order to improve the situation where an air pump is provided with a button for an operator to adjust the gear position, and the button is easily damaged if it is hit during the movement of the air pump, and the button fails in severe cases, the present application provides an air pump.

[0006] The present application provides an air pump that adopts the following technical solution:

[0007] An air pump, comprising:

[0008] Box body;

[0009] An upper cover, fixedly connected to the box body to cover the box body;

[0010] A driving motor is installed in the box body to drive the air pump to inflate;

[0011] A battery, installed in the box body and electrically connected to the drive motor, so as to start the drive motor; and

[0012] An adjustment component is fixedly connected to the upper cover and is used to adjust the inflation rate gear. The adjustment component includes:

[0013] A mechanical encoder fixedly connected to the upper cover and electrically connected to the drive motor to transmit an inflation rate gear position signal; and

[0014] A roller is rotatably connected to the upper cover, a driving shaft is fixedly connected to a side of the roller close to the mechanical encoder, the driving shaft is rotatably connected to the mechanical encoder, the roller partially protrudes out of the plane where a side of the upper cover away from the box body is located, and the upper cover is provided with a through hole for the roller to protrude.

[0015] By adopting the above technical solution, when the operator needs to adjust the inflation rate gear, he turns the roller, and the roller drives the drive shaft to operate the mechanical encoder, and transmits the signal to the drive motor, so that the adjustment component adjusts the drive motor, thereby completing the inflation rate gear adjustment operation. Through the cooperation of the mechanical encoder and the roller, the operating difficulty of the operator is reduced, the operating efficiency of the adjustment operation is improved, the probability of the adjustment component being damaged and ineffective is reduced, and the stability of the signal transmission is enhanced.

[0016] Optionally, a support plate for fixing the adjustment component is fixedly connected in the box body, and an indicator light for displaying the inflation rate gear position is provided on a side of the support plate close to the upper cover, and the indicator light is electrically connected to the adjustment component.

[0017] By adopting the above technical solution, when the operator controls the adjustment component to make adjustments, the indicator light displays the adjustment position, which is convenient for the operator to identify. At the same time, the setting of the support plate reduces the probability of the adjustment component falling into the box body, making it difficult to complete the adjustment operation, thereby reducing the failure rate of the adjustment component.

[0018] Optionally, a first partition plate is fixedly connected to the box body, and a second partition plate is fixedly connected to a side of the upper cover close to the box body. The side of the first partition plate close to the upper cover abuts against the side of the second partition plate close to the box body. The first partition plate cooperates with the second partition plate to divide the box body into a first cavity for installing the drive motor and a second cavity for installing the battery. A side cover for opening and closing the second cavity is rotatably connected to the box body.

[0019] By adopting the above technical solution, when the operator replaces the battery, he only needs to lift up the side cover to open the second cavity without opening the upper cover as a whole, which reduces the difficulty of operating when replacing the battery and improves the work efficiency of the operator. At the same time, it reduces the probability of the driving motor in the first cavity and the battery in the second cavity being damaged by collision due to the movement of the box body, enhances the stability of the components inside the box body, and reduces the failure rate.

[0020] Optionally, a plurality of vertical plates are fixedly connected to the circumferential inner wall of the side cover, and a plurality of the vertical plates form a snap-in groove. A fixing plate is fixedly connected to the box body, and one side of the side cover abuts against one side of the fixing plate. A snap-in block is fixedly connected to the fixing plate, and the snap-in block is snapped into the snap-in groove, and a side of the snap-in block close to the box body abuts against the side wall of the snap-in groove.

[0021] By adopting the above technical solution, when the operator closes the second cavity, the side cover is rotated to abut the inner wall of the side cover against the fixed plate, so that the snap block is snapped into the snap groove, and the side cover is closed. The stability of the side cover when closed is improved, the probability of the battery falling off due to the rotation of the side cover is reduced, the tightness between the side cover and the box body is enhanced, and the safety is improved.

[0022] Optionally, the first partition plate is provided with a groove with an opening toward the second partition plate, and the side of the clamping block close to the first partition plate is fixedly connected with a connecting block, the connecting block is passed through the groove and fixedly connected to the box body, the connecting block is partially embedded in the groove, and the connecting block is provided with an inclined surface for guiding the deformation of the connecting block.

[0023] By adopting the above technical solution, when the operator opens the side cover, the card block is pressed toward the inside of the box body so that the card block is disengaged from the card slot, thereby opening the side cover. At the same time, the inclined surface reduces the interference of the first partition plate on the connecting block, thereby reducing the difficulty of operation, improving the work efficiency of the operator, and enhancing convenience.

[0024] Optionally, a uniformly arranged heat dissipation rack for dissipating heat from the battery is fixedly connected to the circumferential inner side wall of the second cavity.

[0025] By adopting the above technical solution, when the air pump is running, the battery transmits power to the drive motor and dissipates a large amount of heat. The heat dissipation rack avoids direct contact between the battery and the upper cover, the box body and the side cover, reduces the damage to the operator caused by the heat of the battery through the upper cover, the box body and the side cover, and improves safety.

[0026] Optionally, a plurality of positioning posts for positioning the drive motor are fixedly connected in the box body, and reinforcing ribs are fixedly connected on the circumferential outer side walls of the positioning posts.

[0027] By adopting the above technical solution, when the operator installs the drive motor, the positioning column plays a positioning role for the drive motor, which is convenient for the operator to install, reduces the probability of the problem of installation position deviation, and enhances the simplicity. At the same time, the reinforcing ribs enhance the fixing effect of the positioning column, reduces the probability of the positioning column being damaged by collision, and reduces the failure rate.

[0029] By adopting the above technical solution, when the operator installs the side cover, he only needs to put the fixing part on the fixing column to complete the installation of the connecting piece, and then pass the rotating column through the clamping part, which reduces the difficulty of the side cover installation operation and enhances the simplicity. At the same time, the fixing column and the fixing part are adapted to each other to enhance the stability of the installation of the connecting piece.

[0030] Optionally, the connecting member also includes an abutment portion and a clamping portion, the abutment portion is fixedly connected to two opposite sides of the clamping portion, the abutment portion on one side abuts against the circumferential inner wall of the box body, and the abutment portion on the other side abuts against a side of the upper cover close to the box body, and the clamping portion is clamped in the interlayer between the fixed column and the box body.

[0031] By adopting the above technical solution, when the operator installs the side cover, the connecting piece is inserted into the interlayer between the fixing column and the side wall of the box body, thereby enhancing the tightness of the connection between the connecting piece and the box body, reducing the probability of damage to the connecting piece and reducing the failure rate.
