Description

Technical Field

[0001] This utility model belongs to the technical field of fluid dispensing nozzles, specifically relating to a fluid dispensing nozzle. Background Technology

[0002] A metered-dispensing fluid nozzle is a device that can precisely control the amount of liquid dispensed. It typically consists of a pump body, piston, spring, nozzle, and other components. By pressing or other operating methods, the pump body generates pressure, drawing liquid from the bottle and spraying it out through the nozzle. This type of nozzle can precisely control the amount of liquid dispensed each time according to its design, avoiding the problem of difficult-to-control dispensing volume of traditional nozzles. Common types include spray nozzles and dropper nozzles, which can meet the user's needs for the amount of different cosmetics and perfumes used, while also helping to reduce liquid waste and improve the user experience.

[0003] When using a metered-dispensing fluid nozzle, if the type of cosmetic inside the bottle is different and the nozzle is used repeatedly, it needs to be cleaned before use. However, the nozzle's orifice is too narrow, making it too difficult to clean the inner wall of the nozzle. Utility Model Content

[0004] The purpose of this utility model is to provide a quantitative dispensing fluid nozzle to solve the problem mentioned in the background art that when the nozzle is used repeatedly, if the types of cosmetics inside the bottle are different, the nozzle needs to be cleaned before it can be used again. However, the nozzle orifice is too narrow, making it too difficult to clean the inner wall of the nozzle.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quantitative fluid dispensing nozzle, comprising a pump head, wherein multiple limiting grooves are distributed on the inner wall of the pump head, and a threaded cylinder is installed on the inner side of the pump head through the limiting grooves. The threaded cylinder secures multiple limiting strips on the outer wall of the pump head, which are engaged with the inner position of the limiting grooves. A threaded end cap is installed at the lower end of the pump head through the threaded structure on the outer wall of the pump head. A pump core is provided on the inner side of the pump head, and a piston is provided at the upper part of the pump core. A nozzle cover is installed on the upper inner side of the pump head through the piston. The pump core draws in fluid through a suction tube at the lower end, and a spiral tube is provided at the lower end of the suction tube.

[0006] Preferably, the pump core has an internal location that forms a pump chamber, and a stainless steel spring is provided inside the pump chamber.

[0007] Preferably, a nozzle for spraying fluid is provided at the front end of the nozzle cover, and pressing the nozzle cover downwards can cause the piston to move.

[0008] Preferably, the threaded end cap is installed with the pump head through a threaded structure on the inner wall, and the installation of the threaded end cap with the pump head fixes the threaded cylinder on the inner side of the pump head.

[0009] Preferably, the inner wall of the threaded cylinder is provided with a threaded structure, and the pump head is connected to the bottle body through the threaded structure on the inner wall of the threaded cylinder.

[0010] Preferably, the limiting strip is engaged with the inner wall of the limiting groove, thereby fixing the position of the threaded cylinder.

[0011] Preferably, the number of limiting strips and limiting grooves are the same, and multiple limiting strips are engaged in the corresponding limiting grooves.

[0012] Preferably, the spiral tube is the fluid inlet, and the fluid passes through the suction tube and the pump chamber and is ejected from the nozzle.

[0013] Compared with the prior art, this utility model provides a nozzle capable of quantitatively dispensing fluid, which has the following beneficial effects:

[0014] 1. This device has a threaded cylinder installed on the inner wall of the pump head. The cylinder is installed with the bottle through the threaded structure on its inner wall. The threaded cylinder is engaged with the limiting strip in the limiting groove, thus locking the cylinder inside the pump head. The pump head controls the rotation of the threaded cylinder to install it with the bottle. When it is necessary to clean the cosmetics inside the pump head, the threaded end cap can be removed to take the threaded cylinder away for cleaning.

[0015] 2. This device sets the bottom of the straw as a spiral tube. When the straw draws in fluid, it passes through the spiral tube, which then contacts the bottom of the bottle. This allows the straw to draw in liquid more fully within the limited space inside the bottle, reducing liquid residue. Attached Figure Description

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] The utility model provides, for example Figures 1-5The illustrated fluid dispensing nozzle includes a pump head 1. Multiple limiting grooves 10 are distributed on the inner wall of the pump head 1. A threaded cylinder 7 is installed on the inner side of the pump head 1 through the limiting grooves 10. The threaded cylinder 7 secures multiple limiting strips 8 on the outer wall, engaging them within the limiting grooves 10. A threaded end cap 4 is installed at the lower end of the pump head 1 through the threaded structure on the outer wall. A pump core 9 is located on the inner side of the pump head 1. A piston 11 is located at the upper part of the pump core 9. A nozzle cover 2 is installed on the upper inner side of the pump head 1 through the piston 11. Fluid is drawn into the pump core 9 through a suction tube 6 at its lower end. A spiral tube 5 is located at the lower end of the suction tube 6.

[0026] When in use, pressing the nozzle cap 2 causes the piston 11 inside the pump body to press down, compressing the spring and reducing the volume of the pump chamber 12, increasing the pressure. The fluid in the bottle is drawn into the pump chamber 12 through the straw 6. Releasing the nozzle cap 2 causes the spring to rebound and push the piston 11 back to its original position. The pressure change in the pump chamber 12 causes the fluid to be sprayed out from the nozzle 3 in a metered manner, completing one metered delivery. Through this cycle of pressing and rebounding, precise and metered fluid release is achieved, making it suitable for cosmetics and perfume bottles to dispense liquid as needed.

[0027] like Figure 3 and Figure 4 As shown, the pump core 9 has a pump chamber 12 inside, and a stainless steel spring 13 is installed inside the pump chamber 12. The nozzle 3 for spraying fluid is installed at the front end of the nozzle cover 2. Pressing the nozzle cover 2 down can cause the piston 11 to move. The threaded end cap 4 is installed with the pump head 1 through the threaded structure on the inner wall. The installation of the threaded end cap 4 with the pump head 1 fixes the threaded cylinder 7 to the inner side of the pump head 1. The inner wall of the threaded cylinder 7 is provided with a threaded structure. The threaded cylinder 7 connects the pump head 1 to the bottle body through the threaded structure on the inner wall. The limiting strip 8 is engaged with the inner wall of the limiting groove 10 to fix the position of the threaded cylinder 7. The number of limiting strips 8 and limiting grooves 10 is the same. Multiple limiting strips 8 are engaged in the corresponding limiting grooves 10. The spiral tube 5 is the fluid inlet. The fluid passes through the suction tube 6 and the pump chamber 12 and is sprayed out by the nozzle 3.

[0028] A threaded cylinder 7 is installed on the inner wall of the pump head 1. The threaded cylinder 7 is installed with the bottle body through the threaded structure of the inner wall of the threaded cylinder 7. The threaded cylinder 7 is engaged with the limiting strip 8 in the inner position of the limiting groove 10, so that the threaded cylinder 7 is engaged in the inner position of the pump head 1. In this way, the pump head 1 controls the rotation of the threaded cylinder 7 to be installed with the bottle body. When it is necessary to clean the cosmetics in the inner position of the pump head 1, the threaded end cap 4 can be removed to remove the threaded cylinder 7.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
