Embodiment Construction

[0023] Referring to the accompanying drawings, the hollow cylindrical supports of the pump are all indicated by reference numeral 1, the boat cover of the pump is designated 2, and a threaded ring for screwing the pump onto the neck 4 of the liquid container 5 is designated 3 for the liquid supply The container 5 is supplied with liquid through the end 6 of the conduit 7 .

[0024] The trigger-like end of the tie rod 9 is designated 8 and is mounted to rotate about a pivot 10 supported by an axial rib 1a of a cylindrical support.

[0025] The other end 11 of the tie rod 9 is installed in the inner cavity 12 of the hollow cylindrical support body 1, and is composed of two parallel forks 11a, which can be clearly seen from FIG. 8 .

[0026] The end 11 with the fork 11a is in contact with the outer surface 13 of a cup-shaped suction element 14, the inner cavity of which is opposite the end 1b of the cylindrical support 1, thus forming a suction chamber 15.

[0027] See Fig. 9 fo...

Abstract

A liquid supply pump, similar to a traditional pump, includes a support body (1), a conduit (22), a joint (3), a suction member (14) and a pull rod (9), but the pump of the present invention also includes A tubular part (26), its first end stretches in the lumen (15) of suction element (14), and the other end (28) stretches to the liquid supply container (15), and there is a mouthpiece at the first end place (31), with a plate (30) as a valve for opening and closing the port. In the pump of the present invention, the cup-shaped diaphragm of the suction element (14) is surrounded by a continuous deformable flange (23), which acts as a valve for opening and closing the nozzle (21) leading to the conduit (22) pieces. The pump of the invention has compact structure, less parts, and can improve the pumping efficiency of the pump.

Description

field of invention [0001] The invention relates to a liquid supply pump, in particular to a manually operated liquid supply pump with a trigger. Background technique [0002] A general liquid supply pump includes: a hollow cylindrical support body, which has an annular groove that is configured at its first shaft end and opens to its inner cavity; To the protruding conduit, this conduit communicates with the annular groove by a nozzle; the joint piece arranged at the other end of the hollow cylindrical support body connects the pump to the liquid supply container; a suction element, which has a pair of The inner cavity of the annular groove and a surface, the surface is opposite to the joint connected to the liquid supply container, and the suction element is contained in the hollow cylindrical support body; a flange installed on the diaphragm of the suction element, It protrudes radially relative to the inner cavity and is connected to the periphery of the inner wall of th...
