Embodiment Construction

[0036] In order to be able to understand the technical features and practical effects of the present invention in detail, and to implement them according to the contents of the specification, the preferred embodiment shown in the drawings will be described in detail as follows:

[0037] The present invention is a piston of an inflator, please refer to Figure 1 to Figure 3 The preferred embodiment, it comprises a piston connecting rod 10 and a sealing valve member 20, wherein:

[0038] The piston connecting rod 10 includes a handle body 11 and a piston seat 12. The handle body 11 is a long handle with a slightly rectangular cross-section. A semicircle is formed at one end of the handle body 11 and a connecting hole 111 is provided for use. In connection with the transmission part, the other end of the handle body 11 is integrally connected with the piston seat 12. The piston seat 12 includes a base 121, an abutting portion 122, two clamping flanges 123 and two air hole...

Abstract

The invention relates to a piston of a pump, mainly comprising a piston-rod and a seal valve member; the piston-rod is tied at one end to form a disk-shaped piston seat; more than two air holes penetrate through the piston seat; the seal valve member is movably blocked in the piston seat of the piston-rod, and can seal the more than two air holes. According to the invention, the seal valve member is combined with the piston-rod in a direct blocking manner; and the piston has a better sealing effect, and is not easy to deform and produce noises after long term use.

Description

technical field [0001] The invention relates to a piston assembly of an inflator, in particular to a piston of an inflator. Background technique [0002] General inflators are used in households or vehicles and can be used to inflate tires or air mattresses. Generally, the motor drives the piston to reciprocate in the piston cylinder, compressing and extruding the air to form high-pressure gas. This provides an inflated effect. [0003] For example, a piston for an inflator disclosed in the Taiwan New Patent Case with the certificate No. M319326 "Inflating Device" has a piston seat formed on the top of the piston, and an air hole is arranged on the piston seat. There is an elastic reed on the top and it covers the air hole. When the piston moves, the elastic reed will be impacted by the air flow and the piston seat will form an open and close shape, so that the gas will flow into the cylinder and wait for the next time. When the piston moves, the gas is squeezed out from t...
