Description

Technical Field

[0001] This utility model relates to the field of health tea machine technology, specifically a water inlet puncture device. Background Technology

[0002] Currently, there are more and more capsule-type tea makers and health tea makers on the market, and more and more people are using them. Capsule-type direct-inlet tea makers are difficult to achieve the purpose of rapid extraction.

[0003] Currently, most of the products on the market have a straight-in-straight-out structure and are not designed with a check valve; moreover, the extraction efficiency is not high and backflow affects the internal pipeline. Utility Model Content

[0004] This utility model provides a water inlet puncture device, which aims to solve the problems mentioned in the background art, such as the current market generally having a straight inlet and straight outlet structure, without a check valve, low extraction efficiency, and backflow affecting the internal pipeline.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water inlet puncture device, which includes a fixed connector; a hollow puncture needle is fixedly embedded in the top of the fixed connector, and a side water outlet hole is opened on the top of the puncture needle, which is through on both sides and communicates with the inner cavity of the puncture needle; a first sealing ring is fitted on the upper end of the puncture needle, and a second sealing ring is fitted on the lower end of the puncture needle extending to the inner side of the fixed connector; a one-way valve mechanism is provided in the inner cavity of the puncture needle.

[0006] During use, hot water at a certain pressure is injected through the fixed connector. The hot water pushes open the check valve sealing silicone and enters the needle, then sprays out through the side water outlet and finally enters the inner side wall of the capsule. The cylindrical side wall of the capsule creates a vortex stirring effect, which can effectively improve the extraction efficiency of the contents. When the hot water injection is stopped, the first and second springs at the upper and lower ends of the check cone push the check valve sealing silicone back to the initial position to achieve the check valve effect, preventing residual liquid inside the capsule from entering the water injection pipe due to thermal expansion and contraction, causing scale buildup in the pipe.

[0007] Preferably, the one-way valve mechanism includes a check cone rod disposed in the inner cavity of the needle, a first spring and a second spring sleeved at the upper and lower ends of the check cone rod, and a backflow sealing silicone disposed at the bottom of the inner cavity of the needle and abutting against the second spring.

[0008] Preferably, the bottom of the fixed joint is provided with a hot water inlet, and the top of the hot water inlet abuts against the anti-reverse sealing silicone.

[0009] Preferably, the fixed joint has positioning holes at both ends.

[0010] Preferably, the upper end of the first sealing ring is trumpet-shaped, and the lower end abuts against the horizontal stepped surface of the needle.

[0011] Preferably, the tip of the needle is inserted into the inside of the capsule, and the inner wall of the capsule has a cylindrical structure, which facilitates the formation of a vortex stirring effect.

[0012] This water inlet puncture device has a simple structure and is easy to use. It changes the water outlet direction by using a side outlet, creating a vortex stirring effect inside the capsule to improve the extraction efficiency of the contents. At the same time, a one-way valve mechanism is installed at the water inlet to prevent backflow caused by thermal expansion and contraction from affecting the internal pipeline.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This embodiment provides a water inlet puncture device, such as... Figures 1 to 3As shown, the water inlet puncture device includes a fixed connector 1; a hollow puncture needle 2 is fixedly embedded in the top of the fixed connector 1, and a side water outlet hole 21 is opened on the top of the puncture needle 2, which is through on both sides and communicates with the inner cavity of the puncture needle 2. A first sealing ring 3 is sleeved on the upper end of the puncture needle 2, and a second sealing ring 4 is sleeved on the lower end of the puncture needle 2 extending to the inner side of the fixed connector 1. A one-way valve mechanism 5 is provided in the inner cavity of the puncture needle 2.

[0025] In use, hot water at a certain pressure is injected through the fixed connector 1. The hot water pushes open the check valve sealing silicone 54 and enters the needle 2, then sprays out through the side water outlet 21, and finally enters the inner side wall of the capsule. The capsule side wall is cylindrical, which creates a vortex stirring effect, which can effectively improve the extraction efficiency of the contents. When the hot water injection is stopped, the first spring 52 and the second spring 53 at the upper and lower ends of the check cone rod 51 push the check valve sealing silicone 54 back to the initial position to achieve the check valve effect, preventing the residual liquid inside the capsule from entering the water injection pipe due to thermal expansion and contraction, causing scale buildup in the pipe.

[0027] In this embodiment, refer to Figure 2 and Figure 3 Hot water pushes open the check seal silicone 54 and enters the needle 2. At this time, the first spring 52 and the second spring 53 deform, converting the pressure of the hot water into elastic potential energy. When the hot water injection stops, the first spring 52 and the second spring 53 return to their original state, thereby pushing the check seal silicone 54 back to its initial position to achieve the check effect.

[0028] In one embodiment, the bottom of the fixed connector 1 is provided with a hot water inlet 6, and the top of the hot water inlet 6 abuts against the anti-reverse sealing silicone 54.

[0029] In this embodiment, refer to Figure 3 When hot water injection stops, the check seal silicone 54 seals the top of the hot water inlet 6 to prevent residual liquid from flowing back.

[0030] In one embodiment, positioning holes 11 are provided at both ends of the fixed connector 1.

[0031] In this embodiment, refer to Figure 1 By adding positioning bolts to positioning holes 11, it is easy to install the fixed joint 1.

[0032] In one embodiment, the upper end of the first sealing ring 3 is trumpet-shaped, and the lower end abuts against the horizontal stepped surface of the needle 2.

[0033] In this embodiment, refer to Figure 2 This blocks the hot water flow that is sprayed to the side to prevent backflow.

[0034] In one embodiment, the top of the needle 2 is inserted into the inside of the capsule, and the cylindrical structure of the inner wall of the capsule facilitates the formation of a vortex stirring effect.

[0035] In this embodiment, refer to Figure 1 The cylindrical structure of the inner wall of the capsule facilitates the formation of a vortex stirring effect when hot water is sprayed out from the side water outlet 21.
