Description

Technical Field

[0001] This utility model relates to the field of vacuum emulsion nozzle technology, specifically a multi-segment vacuum emulsion nozzle. 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 nozzles, the existing vacuum emulsion nozzles tend to press all the way down without multi-stage buffering, which makes the emulsion easy to splash and difficult to control the liquid output, resulting in waste of emulsion and inconvenience in use. Therefore, we propose a multi-stage vacuum emulsion nozzle. Utility Model Content

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This multi-segment vacuum emulsion nozzle, by pressing the nozzle downwards from top to bottom, drives the retaining ring to collide with the first and second sockets to generate a response force and provide feedback to the user. At the same time, the mutual repulsion force between the first and second magnets provides buffering. The second socket can be fitted into the outer periphery of the first socket and contract, driving the retaining ring into the next interval area, where it collides with the next second socket to generate a response force. Combined with the feedback from the previous step, this forms a multi-segment feedback to the user. The vacuum emulsion nozzle has multi-segment buffering, making the emulsion less prone to splashing, easy to control the liquid output of the emulsion, saving emulsion usage, and convenient to use.

Figure 1-4 A first magnet 150 is fixedly connected to the middle of the left side wall of the inner cavity of the first socket 140 on the left and the middle of the right side wall of the inner cavity of the first socket 140 on the right. The right end of the first magnet 150 on the left and the left end of the first magnet 150 on the right are both S poles. The first magnet 150, whose contact ends are both S poles, can repel the second magnet 181.

[0030] Please refer to it again. Figure 1-4 The inner sidewall of the fixing block 180 is inlaid with a second magnet 181. The left end of the second magnet 181 on the left and the right end of the second magnet 181 on the right are both S poles. The second magnet 181, which are both S poles at their contact ends, can repel the first magnet 150, thereby extending the overall length between the first socket 140 and the second socket 170.

[0031] Please refer to it again. Figure 1-4 A limiting ring 190 is fitted between the inner sidewalls of the second socket 170. The limiting ring 190 is made of polypropylene. The limiting ring 190, made of polypropylene, can cooperate with the positioning ring 160 to prevent the second socket 170 from separating and falling off from the first socket 140.

[0032] Please refer to it again. Figure 1-4 An elastic element 360 is fixedly connected to the top of the inner cavity of the sleeve 350, and a stop block 370 is fixedly connected to the bottom end of the elastic element 360.

The support rod 380 can be used to push the abutment block 370 to slide inside the sleeve 350 to complete the extension and retraction movement of the nozzle 300.

[0034] In summary, the downward pressure on the nozzle 300 causes it to move downward, driving the retaining ring 330 to collide with the first second socket 170, generating a response force and providing feedback to the user. Simultaneously, the repulsive force between the first magnet 150 and the second magnet 181 provides buffering. The second socket 170 can fit around the first socket 140 and contract, driving the retaining ring 330 into the next interval area, where it collides with the next second socket 170 to generate a response force. Combined with the previous feedback, this forms a multi-stage feedback to the user. The vacuum emulsion nozzle has multi-stage buffering, making the emulsion less prone to splashing, easy to control the liquid output of the emulsion, saving emulsion usage, and convenient to use.

[0035] In practical use, those skilled in the art first press their fingers on the top of the nozzle 300, causing the nozzle 300 to work with the connecting seat 310 to drive the pump body 320 and the retaining ring 330 downwards. At the same time, the pump body 320, carrying the retaining ring 330, contacts and collides with the second socket 170. The collision generates a response force that is fed back to the operator through the nozzle 300, reminding the operator to apply a little more pressure to the nozzle 300 at this stage. Under the pressure, the retaining ring 330 pushes the second socket 170 outwards, and is buffered by the mutual repulsion between the first magnet 150 and the second magnet 181 until the retaining ring 330 enters the next interval area and collides with the next second socket 170 to generate a response force, forming a multi-stage feedback and providing multi-stage buffering for the downward movement of the retaining ring 330.
