Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation of an air pump, in particular to a heat dissipation structure of an air pump. Background Technique

[0002] When the cylinder of an air pump is in use, good heat dissipation is required. In the existing heat dissipation of the cylinder, in order to streamline the structure and save resources, the cylinder and the cooling fan are driven by a driving motor with a two-way output shaft at the same time. When using a two-way driving motor, one output shaft is connected to the cooling fan, and the other output shaft is connected to the cylinder transmission mechanism. In the prior art, the cooling fan - cylinder transmission structure - cylinder block forms an I-shaped arrangement or an L-shaped arrangement; in the above two cases, the air flow formed by the cooling fan is directly blown to the entire cylinder transmission structure, that is, the air flow is blocked by the entire cylinder transmission mechanism and is not directly blown to the cylinder block, affecting the heat dissipation effect of the cylinder block. To solve the above problems, the utility model provides a heat dissipation structure of an air pump. Content of the Utility Model

[0003] Aiming at the above-mentioned existing technical deficiencies, the purpose of the utility model is to provide a heat dissipation structure of an air pump, which forms a T-shaped structure through a cooling fan, a two-way driving motor and a cylinder body; the air flow formed by the cooling fan blows vertically to the side surface of the cylinder body; the technical problems raised in the background technique are solved.

[0004] To solve the above technical problems, the utility model adopts the following technical scheme: The utility model provides a heat dissipation structure of an air pump, including: the cylinder body of the air pump, a cooling fan, a two-way driving motor and a cylinder transmission mechanism; the cooling fan, the two-way driving motor and the cylinder body form a T-shaped structure, and the cooling fan and the two-way driving motor are on the same straight line; one output shaft of the two-way driving motor is connected to the cooling fan, and the other output shaft is connected to the cylinder transmission mechanism; the cylinder transmission mechanism is connected to the end of the piston rod; the piston at one end of the piston rod slides and matches in the cylinder body; the two-way driving motor drives the piston rod to make a reciprocating pushing movement through the cylinder transmission mechanism, and the two-way driving motor provides power for the cooling fan and the cylinder at the same time.

[0005] Preferably, the air flow formed by the cooling fan blows vertically to the side surface of the cylinder body; the cylinder transmission mechanism has the least influence on blocking the air flow formed by the cooling fan, and the air flow can blow to the cylinder body more effectively, having a better heat dissipation effect.

[0006] Preferably, the cylinder transmission mechanism includes a crank and a transmission component; one end of the crank is connected to the end of the piston rod; the two-way driving motor drives the crank to rotate through the transmission component.

[0007] Preferably, the transmission assembly includes a driving gear and a driven gear that mesh with each other; the driving gear is connected to an output shaft of the bidirectional driving motor; a gear shaft of the driven gear is connected to the end of the crank.

[0008] Preferably, the diameter of the driving gear is equal to the diameter of the bidirectional driving motor; at this time, since the air flow formed by the cooling fan must pass through the bidirectional driving motor, the air flow blocked by the bidirectional driving motor is inevitable. As long as the size of the driving gear located behind the bidirectional driving motor is not larger than the former, the effect of blocking the air flow will not be increased; and as the diameter of the driving gear increases, the diameter of the driven gear relatively decreases, which can reduce the influence of the driven gear on blocking the air flow; therefore, the diameter of the driving gear being equal to the diameter of the bidirectional driving motor can provide a better heat dissipation effect under this solution.

[0009] Preferably, the transmission assembly includes a driving sprocket and a driven sprocket connected by a transmission chain; the driving sprocket is connected to an output shaft of the bidirectional driving motor; a wheel shaft of the driven sprocket is connected to the end of the crank; the diameter of the driving sprocket is smaller than the diameter of the bidirectional driving motor, reducing the influence on blocking the air flow.

[0010] Preferably, the vertical projection range of the cooling fan on the side of the cylinder body is P; the vertical projection range of the driven sprocket on the side of the cylinder body is Q; Q is outside P; reducing the influence of the transmission assembly on the air flow blocked by the cooling fan and improving the heat dissipation effect.

[0011] The beneficial effects of the present utility model are as follows:

[0012] 1. The present utility model forms a T-shaped structure through the cooling fan, the bidirectional driving motor and the cylinder body; the air flow formed by the cooling fan blows vertically towards the side of the cylinder body; the air flow can blow to the cylinder body more effectively, having a better heat dissipation effect; at the same time, the diameter of the driving gear is equal to the diameter of the bidirectional driving motor, providing a better heat dissipation effect.

[0013] 2. The transmission assembly of the present utility model is a driving sprocket and a driven sprocket connected by a transmission chain; at the same time, the projection range Q of the driven sprocket on the side of the cylinder body is located outside the projection range Q of the cooling fan, reducing the influence of the transmission assembly on the air flow blocked by the cooling fan and improving the heat dissipation effect.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0020] Embodiment 1:

[0021] As Figures 1 to 3 shown, this embodiment provides a heat dissipation structure of an air pump, including: the cylinder body 1 of the air pump, a cooling fan 2, a bidirectional drive motor 3, and a cylinder transmission mechanism; the cooling fan 2, the bidirectional drive motor 3, and the cylinder body 1 form a T-shaped structure. Specifically, the cooling fan 2 and the bidirectional drive motor 3 are on the same straight line. More specifically, the airflow formed by the cooling fan 2 blows vertically towards the side of the cylinder body 1. At this time, the influence of the cylinder transmission mechanism on the airflow formed by the cooling fan 2 is the smallest, and the airflow can blow to the cylinder body 1 more effectively, with better heat dissipation effect. One output shaft of the bidirectional drive motor 3 is connected to the cooling fan 2, and the other output shaft is connected to the cylinder transmission mechanism; the cylinder transmission mechanism is connected to the end of the piston rod 11; the piston at one end of the piston rod 11 slides and mates within the cylinder body 1; the bidirectional drive motor 3 drives the piston rod 11 to make a reciprocating pushing motion through the cylinder transmission mechanism, and the bidirectional drive motor 3 provides power for both the cooling fan 2 and the cylinder at the same time.

[0022] Please refer to Figure 2 and Figure 3As shown in the figure, the cylinder drive mechanism includes a crank 41 and a transmission component; one end of the crank 41 is connected to the end of the piston rod 11; the bidirectional drive motor 3 drives the crank 41 to rotate through the transmission component. Specifically, the transmission component includes a driving gear 42 and a driven gear 43 that mesh with each other; the driving gear 42 is connected to an output shaft of the bidirectional drive motor 3; the gear shaft of the driven gear 43 is connected to the end of the crank 41. More specifically, the diameter of the driving gear 42 is equal to the diameter of the bidirectional drive motor 3; at this time, since the air flow formed by the cooling fan 2 must pass through the bidirectional drive motor 3, the air flow blocked by the bidirectional drive motor 3 is inevitable. As long as the size of the driving gear 42 located behind the bidirectional drive motor 3 is not larger than the former, it will not increase the effect of blocking the air flow; and as the diameter of the driving gear 42 increases, the diameter of the driven gear 43 relatively decreases, which can reduce the influence of the driven gear 43 on blocking the air flow; therefore, the diameter of the driving gear 42 being equal to the diameter of the bidirectional drive motor 3 can provide a better heat dissipation effect under this scheme.

[0023] In this embodiment, a T-shaped structure is formed by the cooling fan 2, the bidirectional drive motor 3 and the cylinder body 1; the air flow formed by the cooling fan 2 blows vertically towards the side surface of the cylinder body 1; the air flow can blow to the cylinder body 1 more effectively, having a better heat dissipation effect; at the same time, the diameter of the driving gear 42 is equal to the diameter of the bidirectional drive motor 3, providing a better heat dissipation effect.

[0024] Embodiment 2:

[0025] The transmission component includes a driving sprocket and a driven sprocket connected by a transmission chain; the driving sprocket is connected to an output shaft of the bidirectional drive motor 3; the axle of the driven sprocket is connected to the end of the crank 41. More specifically, the diameter of the driving sprocket is smaller than the diameter of the bidirectional drive motor 3, reducing the influence of blocking the air flow; the vertical projection range of the cooling fan 2 on the side surface of the cylinder body 1 is P; the vertical projection range of the driven sprocket on the side surface of the cylinder body 1 is Q; Q is outside P; the influence of the transmission component on blocking the air flow of the cooling fan is reduced, improving the heat dissipation effect; based on this design, the design of replacing the transmission chain, the driving sprocket and the driven sprocket with a transmission belt, a driving wheel and a driven wheel is also within the protection scope of this embodiment.

[0026] In this embodiment, the transmission component is a driving sprocket and a driven sprocket connected by a transmission chain; at the same time, the projection range Q of the driven sprocket on the side surface of the cylinder body 1 is located outside the projection range Q of the cooling fan 2, reducing the influence of the transmission component on blocking the air flow of the cooling fan and improving the heat dissipation effect.
