Abstract
The utility model relates to a spray pump with an overhead spring. The spray pump with the overhead spring comprises a pump body (1), a pump ring (2), an upper piston (3), a lower piston (4), an ejector rod (5) and a spring (6), wherein the pump ring is inserted into the upper part of the pump body, the upper piston and the lower piston are arranged in the pump ring, the upper part of the ejector rod is inserted into a stepped hole in the upper piston, the lower part of the ejector rod is inserted into the lower piston, the upper part of the upper piston is connected with a locking switch (7), the upper part of the spring is embedded in a groove (8) of the locking switch, the lower part of the spring is sheathed on the locking switch and the outer walls of the upper piston, a plastic ball (9) is arranged in a stepped hole in the bottom of the pump body, an uncovering head (10) is socket-connected onto the top part of the locking switch, a guide pipe (11) is arranged on the uncovering head and the bottom of the pump body is connected with a sucking pipe (12). By changing the structure of the spray pump and moving the spring to the upper part of the pump body, the situation that the use effect is influenced due to contact and chemical reaction between the spring and liquid can be avoided.
Description
Technical field
The utility model relates to a kind of spray pump, is specifically related to a kind of spring overhead type emulsion pumps.
Background technology
Existing common liquid spray pump, is generally comprised of the pump housing, pump cover, gland, upper and lower piston, valve rod, spring, glass bead and suction pipe etc.During use, on upper piston, load onto nozzle and head, press head during spraying, valve rod is opened thereupon, and in the pump housing, liquid is pressed onto mentioned nozzle area by upper piston hole, and liquid is ejection fast under the effect of pump internal pressure.Because the spring of this spray pump is positioned at the bottom of the pump housing, spring easily contacts attack with liquid in actual use, affects the result of use of liquid.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of spring overhead type spray pump is provided, and prevents that spring from contact with liquid and the chemical reaction that produces, and the result of use of pump is sprayed in raising.
The purpose of this utility model is achieved in that a kind of spring overhead type spray pump, it comprises the pump housing, pump circle, upper piston, lower piston, push rod and spring, described pump circle is plugged on the top of the pump housing, described upper piston and lower piston are all positioned at pump circle, the top of described push rod is plugged in the stepped hole of upper piston, bottom is plugged in lower piston, the top of described upper piston is connected with a locking switch, the top of described spring is embedded in the groove of locking switch, bottom is placed on the outer wall of locking switch and upper piston, in the stepped hole of described pump housing bottom, be provided with baton round, at the top of described locking switch, be plugged with and lift head, described lifting is provided with conduit on head, in the bottom of the described pump housing, be connected with a suction pipe.
The internal face of the outside wall surface of described locking switch and pump circle bottom is threaded connection.
Compared with prior art, the beneficial effects of the utility model are:
The utility model sprays pump structure by change spring is moved to pump housing top, can prevent that spring from contacting with liquid and producing chemical reaction, affects result of use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein:
The pump housing 1
Pump circle 2
Lower piston 4
Push rod 5
Spring 6
