Abstract

This invention relates to a pressure-resistant polymer perfume spray nozzle with a double-fastening rib and its preparation method. It addresses the technical problem of poor stability and easy detachment in existing similar products due to inadequate design of the cap and valve stem fastening structure, making it difficult to load, unload, mix, and spray other liquids. The key feature is that the inner wall of the liquid inlet hole at the cap of this pressure-resistant polymer perfume spray nozzle has two ribs. The ribs of the concave cap and the concave ribs of the valve stem are sealed together, with the straight extensions of the concave ribs positioned on the inner wall of the cap's liquid inlet hole for a seal. A first gap channel is provided between the liquid outlet channel inside the cap and the top plug at the inner and outer connection holes of the cap. When the top plug at the outer connection hole is opened, the nozzle hole at the bottom of the top box body is sealed and fixed to the middle hole of the alumina cap and the outer connection hole of the cap. A second gap channel is provided between the liquid outlet channel inside the cap and the nozzle hole of the top box body inside the cap. When the top box body is pressed, the liquid inside the top box mixes with the liquid inside the cap through the nozzle hole and is sprayed out.

Description

Technical Field

[0001] This invention relates to perfume spray nozzles, specifically a pressure-resistant polymer perfume spray nozzle with a double-buckle cap and its preparation method. Background Technology

[0002] A perfume spray nozzle, also known as a perfume pump, is a miniature sprayer that sprays perfume by pressing a cap, primarily used in the beauty industry. To prevent a chemical reaction between the metal spring inside the pump and the liquid perfume, which could affect the effectiveness of both the perfume and the spring, some perfume pumps use a double spring design, such as application number 201911021949.9 disclosed in Chinese patent literature (publication date 2020.02.21, invention title "Environmentally Friendly High-Rigidity Press-Type Sprayer and its Preparation Method"); and application number 202123115191.0 disclosed in Chinese patent literature (authorization announcement date 2021.12.10, utility model title "Strong-Snap Inner Plug Pressure-Resistant Polymer Perfume Sprayer"). However, the cap and valve stem locking structure of these products is poorly designed, resulting in poor stability and a tendency to detach. The overall structure also needs improvement, and it is difficult to load and unload other liquids for mixing and spraying. Summary of the Invention

[0003] To overcome the above-mentioned shortcomings, the purpose of this invention is to provide a pressure-resistant polymer perfume spray nozzle with a double-buckled cap and its preparation method, thereby solving the technical problems of poor design of the cap and valve stem fastening structure in existing similar products, resulting in poor stability and easy detachment; the need for improvement in the overall structure; difficulty in loading, unloading, mixing, and spraying other liquids; and the need for improvement in the preparation method. This objective is achieved through the following technical solution.

[0004] A pressure-resistant polymer perfume spray head with a double-buckle rib design includes a pump core assembly that is fixed to a raised ring at the top of an alumina retainer via a snap-fit ​​mechanism on the pump body. A valve stem extending from the pump core assembly connects to the inlet hole in the center of the bottom of the spray head. The spray head has an outlet hole with a spray blade, and an alumina cap on its outer diameter. The inner diameter of the cap opening at the bottom of the spray head is above the outer diameter of the ring at the alumina retainer. A gasket is provided on the top ring of the alumina retainer on the outer diameter of the pump body. The key structural design feature is that the inner wall of the inlet hole of the spray head has two ribs, and one end of the valve stem corresponding to these ribs has a concave rib on its outer diameter. The outer diameter below the concave rib of the valve stem is a straight extension. When the ribs of the spray head and the concave rib of the valve stem are sealed together, the straight extension at the concave rib fits and seals with the inner wall of the inlet hole of the spray head. The spray head is a pressure-resistant polymer spray head. Therefore, this structure serves a dual purpose: sealing and increasing pull-out force.

[0005] The pump core assembly has a long spring inside the pump body, one end of which abuts against the bottom of the pump body, and the other end of which abuts against the outer bottom ring of the raised column at the bottom of the valve needle inside the pump body. A ball groove is located in the middle of the bottom of the pump body, and a glass ball is fixed and floats within this groove. A suction tube is located at the bottom of the pump body below the ball groove. The other end of the valve needle is inserted and fixed to the other end of the valve stem inside the pump body. A rib channel is provided on the inner diameter of the valve stem at the fixing point. A piston is located on the outer diameter of the valve stem inside the pump body at the fixing point. A short spring is located on the outer diameter of the valve stem inside the pump body above the piston. One end of the short spring abuts against the piston, and the other end abuts against a limiting rib on the outer diameter of the valve stem inside the pump body above the piston. An inner plug is provided at the pump port inside the alumina bayonet. The outer diameter of the piston abuts against and is limited by a stepped groove on the outer diameter of the inner plug at the bottom of the groove inside the pump body. A through hole is provided on one side of the pump body. The above is a specific embodiment of the pump core assembly structure.

[0006] The annular groove at the top of the piston inside the pump body fits into the annular groove of the valve needle, and the annular groove communicates with the rib channel between the valve needle and the valve stem through a guide groove on one side.

[0007] Above the liquid inlet at the connection between the valve stem and the cap is an external connection hole communicating with the central hole on the alumina cap. The top plug is sealed and fixed to both the central hole of the alumina cap and the external connection hole of the cap. Simultaneously, a first gap channel exists between the liquid outlet channel inside the cap and the top plug inside the cap. When the top plug is opened, the nozzle hole at the bottom of the top housing is sealed and fixed to both the central hole of the alumina cap and the external hole of the cap. A second gap channel exists between the liquid outlet channel inside the cap and the nozzle hole of the top housing inside the cap. When the top housing is pressed, the liquid inside the top housing mixes with the liquid inside the cap through the nozzle hole and is sprayed out. This allows other liquids to be added and mixed from the top of the pressure-resistant polymer perfume spray head as needed.

[0008] The top of the top chamber has a sealing cover that is fastened to the top chamber. A top nozzle cover is also provided at the bottom of the top chamber, connecting the external hole at the top cap and the central hole at the alumina cap. This structure facilitates filling the top chamber with liquid and sealing the top nozzle after removal. Even without the top cover, liquid can still be injected through the top nozzle.

[0009] The pressure-resistant polymer headgear has the following composition and weight ratio in its pressure-resistant polymer material: 100 parts epoxy resin, 50 parts polyvinyl chloride, 50 parts chlorinated polyethylene, 30 parts modified calcium carbonate, 20-10 parts additive ACR, 10-5 parts toughening agent, 5-1 parts initiator, 2-1 parts graphene powder, and 1-0.5 parts antioxidant. The additive ACR consists of heat stabilizers tribasic lead sulfate and dibasic lead phosphite, lubricant caprolactone glycol, and colorant titanium dioxide, with the amounts of the three additives being 5 parts, 60 parts, and 40 parts, respectively.

After plasticization is uniform, the material is fed out, and finally pressed into sheets by a pressure molding machine. It is preheated at 185 degrees Celsius for 10 minutes and degassed 3-6 times. It is first hot-pressed and then cold-pressed. The resulting large masterbatch is crushed by a jaw crusher and then thoroughly crushed by a shear crusher. It is fed into a twin-screw extruder with a processing temperature of 230-260 degrees Celsius and a main screw speed of 700-800 revolutions / minute. The granules are dried at 100 degrees Celsius for 12 hours and then injection molded into pressure-resistant polymer masterbatch with an injection molding temperature of 230-260 degrees Celsius. After demolding, pressure-resistant polymer caps can be obtained.

[0010] The modified calcium carbonate has the following composition and weight ratio: 100 parts heavy calcium carbonate, 50-25 parts oleic acid diethanolamide borate, 25-10 parts polysiloxane urethane acrylate, 20-10 parts solvent, 10-5 parts modifier, and 8-3 parts dispersant.

[0011] This invention features a reasonable structural design, convenient assembly and production, good spraying effect, and feasible preparation method. In particular, it facilitates the mixing and spraying of other liquids by filling the cap and alumina at the top of the cap. It is applicable to the use of double-buckled pressure-resistant polymer perfume spray nozzles and their preparation methods, as well as improvements to the structure and preparation methods of similar products.
