Description

Technical Field

[0001] The utility model relates to an air pump, in particular to a portable air pump. Background Art

[0002] Currently, Chinese patent publication number CN211449116U discloses a portable electrically controlled air pump comprising a housing and a motor. The housing comprises a front cover, a main body, and a rear cover. The front cover is located at the front end of the main body, forming an air chamber between the front cover and the main body. The rear cover is located at the rear end of the main body, forming a power supply chamber between the rear cover and the main body. The front cover is provided with an air inlet, and both the front cover and the main body are provided with extensions, which cooperate to form an air outlet. The air inlet and the air outlet are both connected to the air chamber. The motor is mounted in the main body and is provided with an impeller, which is rotatably mounted in the air chamber. During use, the motor drives the impeller to rotate circumferentially, thereby driving air into the air inlet and out of the air outlet. However, due to its size, the above-mentioned electrically controlled air pump is difficult to fit into a user's pocket, and thus still has the disadvantage of being difficult to carry around. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a portable air pump, which has the advantage of being portable.

[0004] In order to solve the above technical problems, the technical solution of the utility model is: a portable air pump, comprising an air pump body, a motor compartment is provided at the inner rear end of the air pump body, a driving motor is provided in the motor compartment, an air compartment is provided at the inner front end of the air pump body, a fan wheel is provided in the air compartment, the output end of the driving motor extends into the air compartment and is connected to the fan wheel, a lifting block is fixedly provided at the outer side wall of the air pump body, a portable seat is provided at the end of the lifting block, a hanging opening is provided at the lower end of the portable seat, the two ends of the hanging opening respectively pass through the left side wall and the right side wall of the portable seat, and the outer side of the portable seat is detachably connected to a limiting fork, and the limiting fork is used to block the lower end of the hanging opening.

[0005] Through the above technical solution, when in use, the motor is connected to an external power supply, and the motor drives the fan wheel to rotate in the air bin, thereby driving air into the air bin through the air inlet and discharged through the air outlet.

[0006] When the air pump is needed to be carried around, the portable base can be hung on a user's belt or backpack strap via the hanging opening, allowing the user to carry the air pump around. A limit fork can then be installed on the outside of the portable base to block the lower end of the hanging opening, preventing the portable base from being easily removed from the belt or backpack.

[0007] The portable seat is connected to the air pump body by the lifting block, so that a gap for the limit fork to pass through is left between the portable seat and the air pump body, which makes it easier to disassemble and assemble the limit fork.

[0008] Preferably, the limit fork includes a limit plate and connecting plates arranged at both ends of the limit plate. Receiving grooves are provided on the front and rear sides of the portable seat. When the limit plate blocks the lower end of the hanging opening, the two connecting plates are respectively received in the two receiving grooves.

[0009] Through the above technical solution, the receiving groove can be used to accommodate the connecting piece, thereby reducing the space required for the above-mentioned air pump, making the carrying of the above-mentioned air pump more convenient. It can also be used to limit the limit fork, so that the limit fork and the portable seat are not prone to relative movement, thereby ensuring that the above-mentioned air pump is not easily lost during carrying.

[0010] Preferably, a limiting groove is provided on the inner groove wall at the upper end of the receiving groove, and a limiting protrusion is provided on the inner side of the connecting piece opposite to the limiting groove. When the limiting piece blocks the lower end of the hanging opening, the limiting protrusion is stuck in the limiting groove.

[0011] Through the above technical solution, the limiting groove and the limiting protrusion cooperate with each other to improve the connection stability between the limiting fork and the portable seat, thereby ensuring that the above air pump is not easily lost during carrying.

[0012] Preferably, a sliding hole is provided on the connecting piece away from the limiting piece, the limiting protrusion is cylindrical, and the limiting protrusion is slidingly connected in the sliding hole, and an elastic member is provided between the connecting piece and the limiting protrusion, and the elastic member drives the limiting protrusion to be inserted into the limiting groove through elastic force.

[0013] With the above technical solution, during use, the limiting protrusion can be pulled outward so that the end of the limiting protrusion is received in the sliding hole, and the user can now more conveniently install the limiting fork on the outside of the portable stand. When the limiting fork is installed in place, the user only needs to release the limiting protrusion, and the limiting protrusion will be inserted into the stop groove of the driving member of the elastic member to limit the position of the limiting fork.

[0014] Preferably, the outer rotating sleeve of the limiting protrusion is provided with a connecting ring, the elastic member is a pagoda spring, the large end of the pagoda spring is fixedly connected to the connecting piece, and the small end of the pagoda spring is fixedly connected to the connecting ring.

[0015] Through the above technical solution, the pagoda spring is connected to the limiting protrusion through the connecting ring, so that when the limiting protrusion rotates, the pagoda spring is not easily affected.

[0016] Preferably, a receiving groove is provided on the outer side of the connecting piece, the receiving groove is coaxially arranged with the sliding hole, and the large end of the pagoda spring is fixedly connected to the bottom of the receiving groove.

[0017] Through the above technical solution, the storage groove is used to store the pagoda spring, which can reduce the space required for the above air pump to a certain extent, making the carrying of the above air pump more convenient.

[0018] Preferably, an internal thread is provided at the inner groove wall of the limiting groove, and an external thread is provided at the end of the limiting protrusion, and the external thread is used to be screwed together and fixed with the internal thread.

[0019] Through the above technical solution, when the limit fork is installed in place, the limit protrusion can be rotated so that the limit protrusion is threadedly connected to the limit groove. This can further improve the connection stability between the limit fork and the portable seat, thereby ensuring that the above-mentioned air pump is not easily lost during carrying.

[0020] Preferably, the limiting groove passes through the connecting piece and is connected to the hanging opening.

[0021] With the above technical solution, the end of the limiting protrusion can be controlled to press against the belt or shoulder strap by rotating the limiting protrusion, so that the air pump is not easily lost during carrying. BRIEF DESCRIPTION OF THE DRAWINGS
