[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Example 1:
[0019] like Figures 1 to 3 As shown, this embodiment provides an air pump cooling mechanism, including: a cooling pipe 2, an air pump body 3, and a cooling fan 4 installed inside the pump housing 1. The front end of the cooling pipe 2 is connected to the air outlet of the air pump body 3. Specifically, the cooling pipe 2 is connected to the air outlet of the air pump body 3 through an L-shaped adapter pipe 21 to achieve a stable connection. The end of the cooling pipe 2 connected to the air pump body 3 is defined as the front end, and the opposite end is defined as the rear end. The following text uses this front-rear definition. The cooling pipe 2 is connected to the air outlet hose 5. The connection between the cooling pipe 2 and the air outlet hose 5 extends the air outlet length, which facilitates heat dissipation. The air pump body 3 and the cooling fan 4 are respectively installed in the inner front and inner rear of the pump housing 1. The cooling pipe 2 extends from the front end of the pump housing 1 to the rear end of the pump housing 1. In this embodiment, the cooling pipe 2 is a straight pipe. In practice, the cooling pipe 2 can be an arc-shaped pipe or a partially bent pipe, which can be selected according to actual needs. The air pump body 3 and the cooling fan 4 are located on the same side of the cooling pipe 2, which facilitates the arrangement, installation, and heat dissipation. The airflow generated by the cooling fan 4 blows from the inner front part of the pump housing 1 to the inner rear part of the pump housing 1. The airflow generated by the cooling fan 4 effectively dissipates heat from the heat pipe 2, the drive motor 41 and the air pump body 3.
[0020] In this embodiment, a heat dissipation pipe 2 connected to the air pump body 3 is installed inside the pump housing 1. The heat dissipation pipe 2 is connected to the air outlet hose 5 to extend the air outlet length, facilitate heat dissipation, and avoid overheating. At the same time, the airflow generated by the cooling fan 4 effectively dissipates heat from the heat dissipation pipe 2, the drive motor 41, and the air pump body 3, which is convenient and efficient.
[0021] Furthermore, heat pipe 2 is made of metal or ceramic to improve heat dissipation.
[0022] For further details, please refer to Figure 2 As shown, the cooling fan 4 includes a drive motor 41 and a fan 42. The fan shaft of the fan 42 is fixedly connected to the output shaft of the drive motor 41. Inside the pump housing 1, the air pump body 3, the drive motor 41 and the fan 42 are arranged in a linear pattern, that is, the three are on the same straight line, and the direction of this straight line is the same as the length direction of the pump housing 1. The heat dissipation pipe 2 is located within the airflow range formed by the fan 42, ensuring effective heat dissipation of the heat dissipation pipe 2.
[0023] For further details, please refer to Figure 1 and Figure 3 As shown, the rear cover of the pump casing 1 is an air inlet grille 11, and several air outlet holes 12 are evenly distributed on the lower front side plate of the pump casing 1. By setting the air inlet grille 11 and the air outlet holes 12 at the front and rear parts of the pump casing 1 respectively, the airflow can be effectively circulated, which is conducive to heat dissipation.
