Description

Technical Field

[0001] This utility model relates to the field of air pump technology, and in particular to a linear air pump mechanism. Background Technology

[0002] Electric air pumps are a common product. The core component of this product is the air pump mechanism. Currently, the most commonly used air pump mechanisms with good performance and low cost are generally those used in piston-type electric air pumps. The main working principle of this air pump mechanism is to achieve pressurization by driving the piston to reciprocate through an electric motor.

[0003] The current technical problems with air pump mechanisms on the market are: their structural design is unreasonable, and the design of the heat dissipation airflow channel cannot be aligned with the direction of piston movement. As a result, during the heat dissipation process, the airflow needs to pass through a bent heat dissipation airflow channel, resulting in poor heat dissipation effect. At the same time, it also results in a large space occupation of the structure.

[0004] For example, patent document CN209385305U discloses a plastic air pump core, including a plastic body, a plastic output plate, and a power mechanism; the plastic body is an integrally molded structure, which includes a plastic cylinder and a plastic bracket disposed at the air inlet end of the plastic cylinder; the plastic output plate is detachably connected to the air outlet end of the plastic cylinder; the power mechanism includes a motor, a plastic gear disposed on the plastic bracket and powered by the motor, and a plastic rocker arm driven by the plastic gear to realize the reciprocating sliding of the piston in the plastic cylinder.

[0005] Therefore, improvements are needed. Utility Model Content

[0006] The technical problem solved by this utility model is to address the deficiencies in the prior art by providing a linear air pump core to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a linear air pump core, comprising: a fixed bracket; a dual-output shaft motor, the left end of which is mounted on the fixed bracket, and the right end of which is provided with a fan blade; the left end of which is provided with a transmission gear; a transmission gear disc, the lower end face of which has a longitudinally extending main shaft, the main shaft being connected to the fixed bracket via a bearing, and the upper end face of which has an eccentrically arranged eccentric shaft; a piston connecting rod, the right end of which is connected to the eccentric shaft; a cylinder body, which is connected to the fixed bracket, and the left end of which is placed inside the cylinder body; and a quick-connect air nozzle female seat, which is connected to the cylinder body; wherein the axis of the dual-output shaft motor is coaxial with the axis of the cylinder body and the axis of the quick-connect air nozzle female seat.

[0008] Furthermore, the transmission teeth are helical teeth, and the circumferential edge of the transmission gear disk has a toothed ring, and the helical teeth mesh with the toothed ring for transmission.

[0009] Furthermore, the right end of the fixed bracket has a positioning hole, and the left end of the dual output shaft motor has a protrusion that mates with the positioning hole; when the dual output shaft motor is assembled with the fixed bracket, the protrusion of the dual output shaft motor is placed in the positioning hole.

[0010] Furthermore, a one-way valve is provided at the connection point between the quick-connect valve seat and the cylinder body.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] Efficient and compact layout: The dual-output shaft motor is coaxial with the cylinder and quick-connect valve seat, which significantly reduces the lateral space occupied and makes the overall structure more compact. The coaxial design allows the heat dissipation air duct to be coaxial with the piston, which can effectively dissipate heat from each moving part and improve the heat dissipation effect. The overall appearance of the product is also more coordinated and beautiful, with a more compact structure, making it small and portable.

[0013] Optimized transmission structure: It is more labor-saving. When the helical gear is combined, the meshing contact surface is larger, and the kinetic energy conversion efficiency is higher and more stable than ordinary bevel gear or crown gear combinations, and it also has a significant noise reduction function.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0021] In view of the technical problems described in the background art, such as Figure 1-4As shown, a linear air pump core is provided, comprising: a fixed bracket 1; a dual-output shaft motor 2, the left end of which is mounted on the fixed bracket 1, and the right end of which is provided with a fan blade 3; the left end of which is provided with a transmission gear 4; a transmission gear 4 disc, the lower end face of which has a longitudinally extending main shaft 6, the main shaft 6 being connected to the fixed bracket 1 via a bearing 7, and the upper end face of which has an eccentrically set eccentric shaft 8; a piston connecting rod 9, the right end of which is connected to the eccentric shaft 8; a cylinder body 10, which is connected to the fixed bracket 1, and the left end of which is placed inside the cylinder body 10; and a quick-connect air nozzle female seat 11, which is connected to the cylinder body 10; wherein the axis of the dual-output shaft motor 2 is coaxial with the axis of the cylinder body 10 and the axis of the quick-connect air nozzle female seat 11.

[0022] In the above, the fixed bracket 1 is used to install and support the various components. The dual-output shaft motor 2 provides power output, powered by an internal battery or an external power source. One end of the dual-output shaft motor 2 is equipped with a transmission gear 4 to drive the transmission gear 4 disc to rotate; the other end of the dual-output shaft motor 2 is equipped with a fan blade 3 for rotation and heat dissipation. The transmission gear 4 disc is movably connected to the piston connecting rod 9 via an eccentric shaft 8, converting the rotational motion of the transmission gear 4 disc into the reciprocating motion of the piston connecting rod 9 within the cylinder 10. Furthermore, the quick-connect air nozzle seat 11 is connected to the cylinder 10 to realize the air pump's charging function.

[0023] In this technical solution, the dual-output shaft motor 2 is coaxial with the cylinder 10 and the quick-connect air nozzle socket 11, which significantly reduces the lateral space occupied and makes the overall structure more compact. The coaxial design allows the heat dissipation air duct to be coaxial with the piston, which can effectively dissipate heat from each moving part and improve the heat dissipation effect. The overall appearance of the product is also more coordinated and beautiful, the structure is more compact, and it is small and portable.

[0024] As shown in the figure, the transmission tooth 4 is a helical tooth, and the circumferential edge of the transmission tooth 4 disc has a toothed ring, and the helical tooth meshes with the toothed ring for transmission.

[0025] Preferably, the transmission gear 4 uses helical teeth that mesh with the gear ring on the transmission gear 4 disc, which is more labor-saving. When the helical teeth are combined, the meshing contact surface is larger, and the kinetic energy conversion efficiency is higher and more stable than ordinary bevel gear combinations or crown gear combinations, and it also has a more obvious noise reduction function.

[0026] Specifically, the right end of the fixed bracket 1 has a positioning hole 12, and the left end of the dual output shaft motor 2 has a protrusion 13 that cooperates with the positioning hole 12; when the dual output shaft motor 2 is assembled with the fixed bracket 1, the protrusion 13 of the dual output shaft motor 2 is placed in the positioning hole 12.

[0027] To facilitate the assembly of the dual-output shaft motor 2, the protrusion 13 of the dual-output shaft motor 2 is placed in the positioning hole 12 of the fixed bracket 1 and the installation of the dual-output shaft motor 2 is completed by screw locking.

[0028] Specifically, a one-way valve 14 is provided at the connection position between the quick-connect air nozzle seat 11 and the cylinder body 10. This enables unidirectional airflow for inflation.

[0029] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
