Problems solved by technology

[0002] In the existing headrest or neck pillow, it is necessary to inflate at any time according to the need, so as to adjust the fullness of the headrest or neck pillow. The general inflating device includes a manual or electric air pump, and the electric air pump has a relatively slow inflating speed , after the gas pressure in the headrest or neck pillow increases, the inflating speed will be greatly reduced, which cannot meet the normal inflating requirements

Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0021] refer to Figure 1-Figure 3 , an electric inflator, comprising an electric motor 1, a piston 2, a cylinder 3 and an exhaust valve 4, the output shaft of the electric motor 1 is connected to the piston 2, and the piston 2 moves in the cylinder 3 to compress and inflate the gas And delivered to gas equipment, such as a headrest or a neck pillow, the cylinder 3 includes a primary compressed air space 301 and a secondary compressed air space 302, and when the piston 2 moves toward the cylinder head, the primary compressed air space 301 The air is compressed and boosted and discharged into the secondary compressed air space 302. At this time, the vacuum degree of the secondary compressed air space 302 becomes larger, forming a negative pressure, which is conducive to t...

Abstract

The invention discloses an electric inflating device which comprises an electric motor, a piston, an air cylinder and an exhaust valve, wherein an output shaft of the electric motor is connected with the piston, the piston moves in the air cylinder to compress and inflate air, and the electric inflating device is characterized in that the air cylinder comprises a first-stage air compression space and a second-stage air compression space; when the piston moves towards the air cylinder head, air in the first-stage air compression space is compressed, boosted and exhausted into the second-stage air compression space, when the piston moves towards the bottom of the air cylinder, air in the second-stage air compression space is compressed again and exhausted to gas equipment through the exhaust valve, so that multi-stage compression can be achieved. It is guaranteed that the pressure entering the gas equipment is sufficient, and the inflating effect and the inflating efficiency are guaranteed.

Description

technical field [0001] The invention relates to an inflator, in particular to an electric inflator for a headrest or neck rest. Background technique [0002] In the existing headrest or neck pillow, it is necessary to inflate at any time according to the needs, so as to adjust the fullness of the headrest or neck pillow. The general inflating device includes a manual or electric air pump, and the electric air pump has a relatively slow inflating speed. , after the gas pressure in the headrest or neck pillow increases, the inflating speed will be greatly reduced, which cannot meet the normal inflating requirements. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages and deficiencies of the prior art, and provide an electric inflator for pumping air through multi-stage boosting. [0004] The object of the present invention is achieved through the following technical solutions: an electric inflator, comprising an electric m...
