Abstract

The invention relates to a noise elimination pump structure. The noise elimination pump structure comprises a body, a pump hood and a pump hood lid, wherein a motor is arranged in the body; a first cavity is formed between the body and the pump hood; a vane wheel connected with the motor is arranged in the first cavity; an air outlet is formed in the side of the first cavity; an air inlet is formed in the pump hood lid; a second cavity is formed between the pump hood lid and the pump hood; the air inlet, the second cavity, the first cavity and the air outlet are communicated with each other to form an air channel; a noise elimination device is arranged on the air channel. According to the noise elimination pump structure, the noise elimination device is arranged on the air channel of the pump, so that the noise generated by the pump during operating can be eliminated; when the pump is used for charging inflatable products, the noise elimination device is capable of preventing the pump from generating excessive noise and causing trouble to the living of the people.

Description

technical field [0001] The invention relates to the field of pumps, in particular to a noise-absorbing pump structure. Background technique [0002] Inflatable products are widely used because they are light in weight, can be unfolded and retracted according to the needs, and are convenient to use and store, such as inflatable beds and inflatable sofas for home use, and outdoor pools, etc. [0003] The inflatable product needs to be inflated by means of a pump before use, and the inflatable product can be used after it is inflated. When the current pump is inflated, it will generate a lot of noise, which will bring certain troubles to people's lives. Contents of the invention [0004] The object of the present invention is to provide a sound-absorbing pump structure, which is provided with a sound-absorbing device, and the sound-absorbing device can reduce the noise generated when the pump is in operation. [0005] In order to achieve the above object, the technical sche...
