Embodiment Construction

[0022] Now in conjunction with accompanying drawing, the present invention will be further described. Such as Figure 1 to Figure 8As shown, the foam pump includes a suction pipe 1, a glass ball 2, a spring sleeve 3, a spring 4, a pump body 5, a valve stem 6, a valve needle 7, a large ring 8, a gasket 9, a two-way valve 10, a piston 11, a thick wire Net 12, filter plug 13, fine wire mesh 14, duckbill 15, outer cover 16, the glass ball of this foam pump is placed in the suction pipe place in the pump body, and cooperates with the beating surface 501 of the pump body to move and seal, and is sealed by the bottom of the elastic sleeve. The lower sleeve hole 301 controls its beating stroke distance. The spring is inserted into the inner diameter of the valve stem and the outer diameter of the spring sleeve. The upper end of the spring stops at the valve hole rib 601 at the top of the inner diameter of the valve stem. The inner diameter of the spring passes through the valve needl...

Abstract

The invention relates to a press-type foam pump and a discharge rate control method thereof and aims to solve the technical problems that conventional like products are inconvenient in discharge rate changing and controlling, and need to be further improved in structural design. The press-type foam pump is mainly characterized in that an outwardly protruding convex clasp ring and a tapered limit opening are respectively formed at the nesting parts between a valve rod and a pump body, downward movement of a piston driven by a duckbill is the stroke that a limit ring at the external diameter of the valve rod moves downwards to be propped against the limit opening of the pump body, the limit opening of the pump body is provided with a cylindrical glue site protruding toward the interior of the pump body, and the cylindrical glue site is subjected to integral injection molding with the limit opening and the pump body. Therefore, the discharge rate of the foam pump is changed only by changing the structure of the limit opening in the pump body on the basis of not changing the integral structure of the foam pump, that is, the discharge rate of the foam pump is controlled by controlling the downward movement of the piston via the length of the cylindrical glue site. Accordingly, sharing of product parts and the university of automatic assembly equipment are effectively improved, the production efficiency is improved, energy consumption is reduced, and the production cost is lowered.

Description

technical field [0001] The invention relates to a miniature foam pump, which is a press-type foam pump and a spray volume control method thereof. Background technique [0002] Foam pump is a kind of pump body that can produce foam spraying. According to its use and size, it is generally divided into industrial foam pump, fire fighting foam pump, and micro foam pump. Among them, the working principle of the micro foam pump is to use the liquid to form a certain negative pressure around the liquid column after being sprayed at high speed. The negative pressure generates to attract gas into the mixing part, so that the air and liquid are mixed again to form foam. This type of foam pump is mainly used in cosmetic bottle containers such as facial cleanser, such as the patent number ZL200620053700.8 published in Chinese patent documents, the date of authorization announcement was August 8, 2007, and the name of the utility model is "improved foam pump"; The pump includes a screw ...
