Description

Technical Field

[0001] This utility model relates to the field of sprayer technology, specifically to an anti-clogging vacuum emulsion nozzle. Background Technology

[0002] Vacuum emulsion bottles are common packaging containers used to store and preserve liquid cosmetics or skincare products such as emulsions. Their working principle is based on atmospheric pressure and the vacuum principle. When the pump head is pressed, the air inside is expelled, creating a low-pressure zone in the upper part of the bottle. Because the atmospheric pressure outside the bottle is higher than the pressure inside, this pressure difference causes an upward force on the piston, pushing the emulsion upwards and expelling it through the pump head's outlet. When the pump head is released, the spring returns the piston to its original position, and the lower part of the bottle returns to its original state. Simultaneously, air from outside enters the bottle through the pump head's air inlet, replenishing the air lost during emulsion expulsion and maintaining pressure balance inside the bottle for the next emulsion extraction.

[0003] Existing vacuum emulsion nozzles lack internal anti-clogging mechanisms during use. When foreign objects are present in the storage bottle, they can easily clog the vacuum pump, preventing the emulsion from being drawn in. Furthermore, if the sealing cap is forgotten or lost, foreign objects can easily enter the interior through the outlet, contaminating the emulsion and affecting its quality. To address this, we have proposed an anti-clogging vacuum emulsion nozzle. Utility Model Content

[0004] The purpose of this invention is to provide an anti-clogging vacuum emulsion nozzle to solve the problems mentioned in the background art, such as the lack of an internal anti-clogging mechanism in existing vacuum emulsion nozzles during use, the easy blockage of the vacuum pump body when there are foreign objects in the storage bottle, making it impossible to draw in the emulsion, and the easy entry of foreign objects into the interior through the outlet when the sealing cap is forgotten or lost, causing contamination of the emulsion and affecting its quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-clogging vacuum emulsion nozzle, comprising a bottle body, an outer cap, a nozzle cap, and a connector. The outer cap is threadedly connected to the top of the bottle body, and the nozzle cap is located above the outer cap. The connector is fixedly connected to the liquid outlet end of the nozzle cap. A vacuum pump is provided in the inner cavity of the bottle body, and a filter element is inserted into the bottom end of the vacuum pump. A pressure plate is inserted into the inner side wall of the outer cap, and a piston rod assembly is inserted into the top of the pressure plate. A slider is slidably connected to the inner side wall of the connector, and a sealing plate is fixedly connected between the inner ends of the slider. A guide rod is fixedly connected to the middle of the left side wall of the sealing plate, and an adjusting element is rotatably connected to the left side wall of the connector.

[0006] As a further description of the above technical solution:

[0007] A clip is fitted onto the lower side of the outer wall of the vacuum pump, and the end of the filter element is fixedly connected to the end of the clip.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This anti-clogging vacuum emulsion nozzle features a filter and a clip at the bottom of the vacuum pump, which are plugged in and fixed to the pump. The guide tube is inserted into the inner cavity of the filter. During extraction, it filters foreign objects from the bottle and can be easily disassembled, effectively preventing vacuum pump clogging. A connector is located at the outlet of the nozzle cap, with a sliding seal to close the opening. A guide rod on the seal slides through a guide hole in an adjusting element. Rotating the adjusting element clockwise or counterclockwise allows the seal to slide inward or outward, closing and opening the outlet.

[0036] In summary: By installing a filter element 130 and a clip 120 at the bottom of the vacuum pump 110 and fixing them to the bottom of the vacuum pump 110 by plugging them in, and inserting a conduit 140 into the inner cavity of the filter element 130, foreign objects inside the bottle 100 are filtered during extraction. The conduit is also freely detachable, effectively preventing the vacuum pump from clogging. At the same time, a connector 400 is installed at the liquid outlet of the cap 300. A sealing plate 420 is installed on the connector 400 to slide and close the opening of the connector 400. A guide rod 430 is installed on the sealing plate 420 and slides in the guide hole 450 of the adjusting member 440. By rotating the adjusting member 440 clockwise or counterclockwise, the sealing plate 420 slides inward or outward to close and open the liquid outlet. This effectively prevents foreign objects from entering from the liquid outlet and contaminating the emulsion, ensuring the quality of the emulsion.
