Problems solved by technology

[0003] In the existing market, most of the piston chambers with a built-in spring structure are used as the compression chamber. The spring is soaked in the liquid for a long time, which is prone to embrittlement, corrosion and fracture failure, resulting in failure of the entire sprayer. In addition, when the sprayer is recycled as waste, the metal The springs and other plastic parts are divided into different recovery categories, which cannot be directly broken by the machine, and it becomes very troublesome to disassemble the metal parts
In order to solve this problem, as in the patent No. CN201210412068.1 "Improved structure of plastic spring of hand button sprayer and its use method", it is designed to solve the technical problem of poor structural design of existing similar products

Embodiment Construction

[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0036] A sprayer with an oblique piston cavity and a clasp, which consists of a main body, a large cap connected to the bottle body, a straw, a water inlet check valve, a piston chamber, a diversion channel, a water outlet check valve, an atomizing nozzle, and a head cap. The piston in the piston chamber is connected to the trigger, and the shaft of the handle is set under the outlet check valve. The diversion channel is divided into a vertical liquid inlet channel and a horizontal horizontal liquid outlet channel. The liquid inlet channel includes a suction pipe and an inlet valve. The water one-way valve leads to the piston chamber, and the liquid outlet channel passes through the water outlet one-way valve from the outlet of the piston chamber to the head cap.

[0037] Wherein the inclination angle of the piston chamber is 30 degrees to 60 degrees, and the...

Abstract

The invention discloses a handle type sprayer with an inclined piston cavity. The piston cavity is arranged in an inclined mode, a 7-shaped plastic spring is adopted as a reset element to reset a trigger, an attaching part, an elastic part and a hook part are arranged on the plastic spring, a prying block and an ejection block which correspond to each other are arranged on the trigger, a push block and a pull-back rod are arranged below the trigger, and the pull-back rod is matched with a universal ball head arranged on the top of the piston. According to the sprayer, a two-section type energy storage reset plastic spring structure is adopted, and compared with an existing hand buckling type sprayer, the sprayer is better in hand feeling, rapid in reset starting, and longer in service life.

Description

technical field [0001] The invention relates to a sprayer, in particular to an inclined piston cavity clasp-hand sprayer. Background technique [0002] The working process of a small sprayer is as follows: connect a suction pipe to an inlet check valve, introduce a piston cavity whose space can change, and then connect to the outlet check valve at the outlet through a diversion channel, and then enter the to the atomizing nozzle. Wherein the compression chamber is provided with a reset mechanism, and the reset mechanism is usually composed of a trigger and an elastic element, and the trigger is also called a clasp. The spray nozzle is usually arranged horizontally, while the straw is vertically arranged in the bottle body, and a handle movement mechanism is also arranged near the nozzle mouth, and the handle is connected with the piston part of the compression chamber. Squeeze the trigger to shrink the space of the compression chamber. Since the inlet one-way valve is clos...
