Description

Technical Field

[0001] This utility model relates to the field of vacuum emulsion spray nozzle technology, specifically a vacuum emulsion spray nozzle for anti-backflow cream bottles. Background Technology

[0002] Early emulsion pump heads relied on springs and valves, but these had problems such as insufficient sealing and easy oxidation of the liquid. To solve these problems, packaging manufacturers combined the industrial vacuum jet principle with the pump head. By using vacuum negative pressure to isolate air, the contents are reduced from contact with the outside world, significantly extending the shelf life. This type of emulsion nozzle is also called a vacuum emulsion nozzle.

[0003] Currently, in the use of vacuum emulsion sprayers, due to their simple structure and lack of backflow prevention at the outlet, some of the emulsion that has come into contact with air is easily carried back into the pump body after use, causing the emulsion to deteriorate, making it inconvenient to use and reducing the efficiency of the vacuum emulsion sprayer. To address this, we have proposed a vacuum emulsion sprayer for cream bottles that prevents backflow. Utility Model Content

[0004] The purpose of this invention is to provide a vacuum emulsion spray nozzle for anti-backflow cream bottles, in order to solve the problem mentioned in the background art that the existing vacuum emulsion spray nozzles have a simple structure and lack a backflow restriction structure at the outlet, which makes it easy for some of the emulsion that has been in contact with air to flow back into the pump body after use, thereby causing the emulsion to deteriorate, making it inconvenient to use and reducing the efficiency of the vacuum emulsion spray nozzle.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vacuum emulsion spray nozzle for anti-backflow cream bottles, comprising a housing, a mounting groove, a nozzle, and a sealing element. The mounting groove is located at the top center of the housing. The nozzle is slidably connected to the inner cavity of the mounting groove. The sealing element is inserted into the bottom center of the inner cavity of the mounting groove. A sleeve is fixedly connected to the middle of the left and right sides of the bottom of the inner cavity of the mounting groove. An elastic element is fixedly connected to the middle of the bottom of the inner cavity of the sleeve. A push block is fixedly connected to the top of the elastic element. A support ring is fixedly connected between the upper sides of the inner sidewall of the nozzle. A connecting seat is fixedly connected to the top of the inner cavity of the nozzle. A limiting seat is fixedly connected to the bottom of the connecting seat. A pump body is slidably connected to the inner cavity of the sealing element. The top of the pump body is fixedly connected to the top of the inner cavity of the limiting seat.

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

[0007] A sealing plate is fixedly connected between the lower inner wall of the housing and the bottom of the housing, and a first one-way valve is inserted between the bottom of the sealing plate and the bottom of the housing.

[0008] As a further description of the above technical solution:

[0009] A push rod is fixedly connected to the top of the push block, and the push rod passes through the middle of the top of the inner cavity of the sleeve and is fixedly connected to the bottom of the support ring.

[0010] As a further description of the above technical solution:

[0011] A second one-way valve is inserted into the top of the inner cavity of the limiting seat and the connecting end of the connecting seat. The second one-way valve is located in the inner cavity of the pump body.

[0012] As a further description of the above technical solution:

[0013] A limiting ring is fitted onto the lower side of the outer wall of the pump body, and the limiting ring is made of polyoxymethylene material.

[0014] As a further description of the above technical solution:

[0015] A guide ring is provided between the upper sides of the inner wall of the pump body, and the guide ring is made of polypropylene.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: The vacuum emulsion nozzle for the anti-backflow cream bottle achieves a seal by connecting the pump body outlet port with the limiting seat. This forces the emulsion drawn by the pump body to be discharged into the connecting seat only through the second one-way valve, and then discharged through the nozzle after being guided through the connecting seat. The second one-way valve also prevents the emulsion that flows back through the connecting seat from entering the pump body. This results in a backflow restriction structure at the outlet of the vacuum emulsion nozzle, preventing the vacuum emulsion nozzle from bringing some of the emulsion that has been in contact with air back into the pump body. This reduces the phenomenon of emulsion deterioration, makes it easier to use, and improves the efficiency of the vacuum emulsion nozzle. Attached Figure Description

An elastic element 220 is fixedly connected to the middle of the bottom of the inner cavity of the sleeve 210. A push block 230 is fixedly connected to the top of the elastic element 220. The mounting groove 200 is opened in the middle of the top of the housing 100.

[0028] Please refer to it again. Figure 1-4 A support ring 310 is fixedly connected between the upper inner wall of the nozzle 300 and the upper inner wall of the nozzle 300. The support ring 310 facilitates the nozzle 300 to apply pressure to the push rod 240. A connecting seat 320 is fixedly connected to the top of the inner cavity of the nozzle 300. A limiting seat 330 is fixedly connected to the bottom of the connecting seat 320. The connecting seat 320 is used to cooperate with the limiting seat 330 to dock with the pump body 410. The nozzle 300 is slidably connected to the inner cavity of the mounting groove 200. The nozzle 300 is used to draw out the emulsion from the pump body 410.

[0029] Please refer to it again. Figure 1-4 The inner cavity of the seal 400 is slidably connected to the pump body 410. The top end of the pump body 410 is fixedly connected to the top of the inner cavity of the limiting seat 330. The pump body 410 is used to draw emulsion. The seal 400 is inserted into the middle of the bottom of the inner cavity of the mounting groove 200. The seal 400 is used to limit the up and down sliding movement of the pump body 410.

[0030] Please refer to it again. Figure 1-4 A sealing plate 110 is fixedly connected between the lower inner wall of the housing 100 and the bottom of the housing 100. A first one-way valve 120 is inserted between the bottom of the sealing plate 110 and the bottom of the housing 100. The sealing plate 110 and the first one-way valve 120 can draw emulsion into the housing 100 in one direction.

[0031] Please refer to it again. Figure 1-4 A push rod 240 is fixedly connected to the top of the push block 230, and the push rod 240 passes through the middle of the top of the inner cavity of the sleeve 210 and is fixedly connected to the bottom of the support ring 310. The push rod 240 can be forced to cooperate with the push block 230 to compress the elastic element 220 to shrink.

[0032] Please refer to it again. Figure 1-4 A second one-way valve 340 is inserted into the top of the inner cavity of the limiting seat 330 and the connecting end of the connecting seat 320. The second one-way valve 340 is located in the inner cavity of the pump body 410. The second one-way valve 340 can cooperate with the limiting seat 330 to allow the emulsion discharged from the pump body 410 to be introduced into the connecting seat 320 in one direction.

[0033] Please refer to it again. Figure 1-4A limiting ring 420 is fitted on the lower side of the outer wall of the pump body 410. The limiting ring 420 is made of polyoxymethylene material, which has high wear resistance.

[0034] Please refer to it again. Figure 1-4 A guide ring 430 is provided between the upper inner side wall of the pump body 410. The guide ring 430 is made of polypropylene and has high corrosion resistance.

[0035] In summary, by connecting the discharge port of the pump body 410 with the limiting seat 330 to achieve a seal, the emulsion drawn by the pump body 410 can only be discharged into the connecting seat 320 through the second one-way valve 340, and then discharged through the nozzle 300 after being introduced through the connecting seat 320. The second one-way valve 340 also prevents the emulsion that flows back through the connecting seat 320 from entering the pump body 410. This gives the vacuum emulsion nozzle outlet a backflow restriction structure, preventing the vacuum emulsion nozzle from bringing some of the emulsion that has been in contact with air back into the pump body 410, thereby reducing the phenomenon of emulsion deterioration, facilitating use, and improving the efficiency of the vacuum emulsion nozzle.

[0036] In practical use, those skilled in the art first manually press the nozzle 300 downwards. The nozzle 300, under pressure, cooperates with the support ring 310 to press the push rod 240 downwards. The push rod 240, in conjunction with the push block 230, presses the elastic element 220 downwards, compressing it. Simultaneously, the pump body 410 moves downwards, extracting and extruding the emulsion inside the housing 100. The emulsion is guided through the guide ring 430 into the second one-way valve 340, and then discharged through the second one-way valve 340 into the connecting seat 320. Finally, it is guided through the connecting seat 320 into the spray nozzle. After the nozzle 300 is discharged, the elastic element 220 rebounds and pushes the push block 230 to move upward. At the same time, the push rod 240, in conjunction with the support ring 310, drives the nozzle 300 to reset. This causes the pump body 410 to move inside the seal 400, generating negative air pressure. This pressure then drives the housing 100, in conjunction with the sealing plate 110 and the first one-way valve 120, to draw the emulsion into the housing 100 to complete the filling. Meanwhile, due to the characteristics of the second one-way valve 340, the returned emulsion cannot enter the pump body 410 and merge with the emulsion inside the housing 100.
