Description

Technical Field

[0001] The utility model relates to the technical field of spray nozzles, in particular to an emulsion spray nozzle made of a high-rigidity polymer material based on a plastic center ring structure. Background Art

[0002] The emulsion nozzle made of high-rigidity polymer material based on plastic center ring structure is a special nozzle design that combines the advantages of high-rigidity polymer material and plastic center ring structure. It is mainly used for uniform spraying of emulsion or other liquids.

[0003] Currently, existing emulsion nozzles are unable to filter out impurities in the liquid before pumping, causing the impurities to enter the pump body and rub and collide with its internal parts, resulting in wear and damage to the parts inside the pump body. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art that impurities in the liquid cannot be filtered out before the liquid is pumped, resulting in wear and damage to parts inside the pump body, and to propose an emulsion nozzle based on a high-rigidity polymer material with a plastic middle ring structure.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] The emulsion nozzle is made of high-rigidity polymer material based on the plastic center ring structure, including:

[0007] A pump body, wherein a screw cap is fixedly provided on the outside of the pump body, a pressure head is slidably provided on the top of the pump body, a bellows is sleeved on the outside of the pressure head, the top of the bellows is connected to the bottom of the pressure head, and the bottom of the bellows is connected to the top of the screw cap;

[0008] The filter assembly is arranged on the pump body and is used to filter impurities in the liquid.

[0009] In one possible design, the filter assembly includes a detachable snap-fit ​​frame arranged at the bottom of the pump body, the inner ring of the snap-fit ​​frame is fixedly provided with a filter screen, and two openings are symmetrically provided on both sides of the snap-fit ​​frame for easy disassembly of the snap-fit ​​frame.

[0010] In one possible design, a piston is slidingly provided inside the pump body, a spring is provided inside the pump body below the piston, a ball is movably provided inside the pump body below the spring, and the spring and the ball can be disengaged from each other.

[0011] In a possible design, a stop block is fixedly provided at the bottom of the pressure head, and the bottom of the pressure head is detachably inserted into the piston. The stop block is located at the bottom of the piston and abuts against the top of the spring.

[0012] In a possible design, a liquid suction tube is detachably provided at the bottom of the pump body, and a connecting tube is slidably provided at the bottom of the liquid suction tube.

[0013] In a possible design, a liquid outlet is provided on one side of the pressure head, a cap is provided on the outside of the liquid outlet of the pressure head, and a plurality of evenly distributed anti-slip strips are fixedly provided on the top of the pressure head.

[0014] In this application, when starting to use, first check the cleanliness of the filter as needed. When the filter needs to be cleaned or replaced, take out the filter assembly, that is, the snap-on frame and the filter inside it, remove the snap-on frame from the bottom of the pump body through the opening, clean the filter or replace it with a new one to ensure the filtering effect, re-fix the cleaned or replaced filter on the inner ring of the snap-on frame, and reinstall it back to the bottom of the pump body through the snap-on frame, check the firmness of the connecting pipe and the suction pipe to ensure that they are not loose or damaged.

[0015] Then connect the lotion nozzle to the required liquid container, fix the pump body on the container by screwing the cap, and ensure that the suction tube is inserted into the liquid. At the same time, the length of the suction tube can be adjusted by sliding the connecting tube as needed to ensure that the suction tube can reach the bottom of the liquid. Press the pressure head, and the bellows will expand and contract with the movement of the pressure head, providing comfortable tactile feedback. At the same time, the bellows can prevent dust from entering the sliding connection between the pump body and the pressure head. The bottom block of the pressure head will push the piston downward, compress the spring, and the ball is pushed against the liquid inlet of the pump body to prevent liquid backflow. At this time, the compressed air will be discharged from the liquid outlet of the pressure head, releasing the pressure head, and the spring returns to its original state, pushing the piston and pressure head to reset, and the ball returns to its original position, allowing the liquid to enter the upper part of the pump body through the gap between the filter screen and the inner wall of the ball and the pump body. During the piston reset process, the liquid in the upper part of the pump body flows out through the liquid outlet of the pressure head.

[0016] After use, put the cap on the outside of the liquid outlet of the pressure head to prevent accidental outflow of liquid and entry of dust. If it is not used for a long time, it is recommended to remove the lotion nozzle from the container, clean it and store it in a dry place. If necessary, you can remove the pump body from the container by unscrewing the cap, and then remove the pressure head, piston, spring, ball and other components separately for cleaning. After cleaning, reassemble the components back to the lotion nozzle in the reverse order.

[0017] The utility model has the following beneficial effects:

[0018] The utility model provides a bellows cover to effectively prevent dust and other impurities from entering the sliding connection between the pump body and the pressure head, thereby reducing wear and damage to the sliding connection between the two and extending the performance and life of the pump body. At the same time, when the pressure head is pressed, the bellows cover will expand and contract with the movement of the pressure head, without hindering the normal use of the emulsion spray head.

[0019] The filter assembly is arranged, so that the liquid is filtered before being pumped, thereby filtering out impurities in the liquid, avoiding the impurities from entering the pump body and rubbing and colliding with the parts in the pump body, thereby protecting the parts in the pump body from being abraded and damaged.

At this time, the compressed air will be discharged from the liquid outlet of the pressure head 3, releasing the pressure head 3, and the spring 102 returns to its original state, pushing the piston 101 and the pressure head 3 to reset, and the ball 103 returns to its original position, allowing the liquid to enter the upper part of the pump body 1 through the gap between the filter 401 and the ball 103 and the inner wall of the pump body 1. During the resetting process of the piston 101, the liquid in the upper part of the pump body 1 flows out through the liquid outlet of the pressure head 3.

[0032] A stop block 301 is fixedly provided at the bottom of the pressure head 3. The stop block 301 is located at the bottom of the piston 101 and abuts against the top of the spring 102. The bottom of the pressure head 3 can be detachably inserted into the piston 101, thereby facilitating overall disassembly, cleaning and replacement.
