A kind of foam pump filter screen tube and foam pump filter screen tube production method

Abstract

The invention specifically relates to a foam pump screen tube and a production method thereof, belonging to the field of foam pumps. The foam pump screen tube comprises a tube head and a tube tail both equipped with a foam communicating channel, and filter screen structures integrally molded with the tube head and the tube tail, respectively, wherein the tube head and the tube tail are of a splitstructure; the filter screen structures are arranged on the tail ends of the tube head and the tube tail, respectively; the tube head sleeves the tube tail; and the tube head and the tube tail are ofa mutual sleeving structure relative to each other. According to the invention, the tube head and the corresponding filter screen structure are integrally molded through injection molding, and the tube tail and the corresponding filter screen structure are integrally molded through injection molding; so compared with a traditional ultrasonic welding manner, the foam pump screen tube provided by the invention can avoid the phenomenon that the screen cloth of welded screen tubes has insufficient flatness, prevents foam from disorders during cutting of the foam via the filter screen structures, and allows foam sprayed by a foam pump to be more stable. Moreover, the production method of the invention can reduce direct contact between the produced foam pump screen tube and people and decrease circulation of the produced foam pump screen tube, so contamination is reduced.

Description

technical field

[0001] The invention relates to the field of foam pumps, in particular to a foam pump filter pipe and a production method for the foam pump filter pipe. Background technique

[0002] Foam pump is a new product of pump products. In terms of production, the existing foam pump is to first injection mold the pipe body, and then install the pipe body on the ultrasonic machine and weld the filter screen at both ends of the head and tail twice. However, the foam pump structure produced by this method is not conducive to people's daily use, and also has the following disadvantages: First, the existing process is limited by the production capacity of ultra-single wave welding, and the process requirements for ultrasonic processing are high, which cannot be realized. Automated production has a very low production capacity, and the existing process for making filter tubes requires first forming the tube body on an injection molding machine, and then welding the network ...
