Description

TECHNICAL FIELD

[0001] The utility model relates to a pumping technology field, concretely relates to detachable pumping of heat dissipation structure. BACKGROUND

[0002] In the field of inflator pump, with the development and progress of technology, brushless motor is outstanding in market competition because of its obvious advantages, such as small size and convenient carrying, high working efficiency and long service life, gradually replaces traditional brush motor and becomes mainstream driving device of inflator pump product.

[0003] During the high-efficiency operation of brushless motor, a large amount of heat energy is inevitably generated due to its high power density and rapid electric energy conversion. This heat accumulation leads to a sharp rise in the overall temperature of the inflator pump, especially in the case of long-time continuous use, the temperature often rises to 70-80 degrees Celsius or even higher. Such high temperature brings many problems to the use of inflator pump. On the one hand, high temperature makes the body shell of inflator pump hot, which seriously affects the holding experience of the user, and may even cause the user to hold the device normally, increasing the inconvenience and insecurity of use. On the other hand, the inflator pump is usually equipped with rechargeable lithium battery, which is sensitive to working temperature. Excessive temperature will have a negative impact on its performance, such as shortening battery life, reducing battery capacity, increasing battery bulging and even explosion, etc. safety risks, thereby greatly reducing the overall reliability and safety of the inflator pump.

[0004] To solve this problem, the current market generally adopts the method of installing a silica gel sleeve on the outside of the inflator pump to try to isolate the heat transfer to the user's hand. However, the heat insulation effect of silica gel sleeve is limited, and in the process of long-time continuous inflation operation, heat will still gradually penetrate through the silica gel sleeve, which cannot fundamentally solve the problem of hot body shell, and there is still a risk of burning the user's hand. Moreover, the silica gel sleeve may affect the heat dissipation efficiency of the inflator pump, causing further accumulation of internal heat, which is not conducive to the long-term stable operation of the equipment.
