Description

Technical Field

[0001] This utility model relates to the technical field of hydrogen-rich water stations, specifically to a hydrogen water station water injection device and a hydrogen water station. Background Technology

[0002] Hydrogen-rich water stations are self-service water dispensers that specifically provide hydrogen-rich water. Hydrogen-rich water refers to water with a high concentration of hydrogen gas, which is believed to have health benefits such as antioxidant and anti-inflammatory properties. These stations typically use specialized equipment to dissolve hydrogen gas in water for consumers to drink.

[0003] Hydrogen is a gas that easily escapes, readily escaping from water under normal pressure. Therefore, pressure tanks are typically used for water dispensing. By using pressure tanks, the escape of hydrogen can be effectively reduced, thereby maintaining the hydrogen concentration in the hydrogen-rich water and extending its effectiveness.

[0004] However, pressure tanks typically have a pressure tank ball valve, such as the pressure tank ball valve disclosed in CN209818883U, which includes: a valve body, a valve core, and a handle. The handle is sleeved on one end of the valve body, and a plug-in post is integrally provided on the side of the handle near the valve core. The valve core has a plug-in groove for the plug-in post to be inserted into. An anti-disengagement ring is formed by an inward protrusion on the inner peripheral wall of the handle near the valve body, and a locking groove is provided on the outer peripheral wall of the valve body near the handle for the anti-disengagement ring to be engaged and rotated. Although this type of pressure tank ball valve is easy to connect to the pipeline, the pipeline needs to be removed by pressing the abutment ring during disassembly. However, because the area of ​​the abutment ring is too small, it often needs to be pressed with fingers, which is very inconvenient, and repeated pressing can be accompanied by pain.

[0005] In the hydrogen-rich water station water injection device disclosed in CN220814095U, the water injection pipe and the hydrogen-rich water tank are separated by direct plugging and unplugging. However, this method is not suitable for pressure tanks and may even damage the ball valve of the pressure tank. Utility Model Content

[0006] The purpose of this application is to solve the above-mentioned problems and provide a hydrogen water station injection device. This injection device adds a connector to the injection pipe, and the connector is connected to the injection pipe by an elastic element. When disassembly is required, pushing the connector can press the locking structure of the pressure tank ball valve to loosen the lock on the injection pipe. Under the push of the elastic element, the output end of the injection pipe is separated from the pressure tank ball valve. This is very convenient, and the structure is simple and economical. Simultaneously, this application also provides a hydrogen water station.

[0007] To achieve the above objectives, this application adopts the following technical solution:

[0008] A hydrogen water station water injection device includes a water injection pipe and a connector. The connector is connected to the water injection pipe through an elastic element, and the connector is slidably connected to the output end of the water injection pipe.

[0009] By compressing the elastic element, the output end of the water injection pipe can be passed through the connector, so that the output end of the water injection pipe can be connected to the external pressure tank ball valve, and locked by the locking structure of the pressure tank ball valve.

[0010] By pushing the connector, the locking structure of the pressure tank ball valve can be pressed to loosen the lock on the water injection pipe, and the output end of the water injection pipe can be separated from the pressure tank ball valve under the push of the elastic element.

[0011] Meanwhile, this application also provides a hydrogen water station, including an outer shell, a hydrogen water station water injection device as described above connected inside the outer shell, a hydrogen water delivery device and a pressure tank placement platform inside the outer shell, and a water injection pipe connected to the hydrogen water delivery device.

[0012] Compared with the prior art, the beneficial effects of this application are:

[0013] This application adds a connector to the water injection pipe, and the connector is connected to the water injection pipe by an elastic element. When disassembly is required, the locking structure of the pressure tank ball valve can be pressed by pushing the connector to loosen the locking of the water injection pipe. Under the push of the elastic element, the output end of the water injection pipe is separated from the pressure tank ball valve. This is very convenient, and the structure is simple and economical.

Detailed Implementation

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0021] Example 1

[0022] refer to Figures 1-2 A hydrogen water station water injection device includes a water injection pipe 1 and a connector 2. The connector 2 is connected to the water injection pipe 1 through an elastic member 3, and the connector 2 is slidably connected to the output end of the water injection pipe 1.

[0023] By compressing the elastic element 3, the output end of the water injection pipe 1 can pass through the connector 2, so that the output end of the water injection pipe 1 can be connected to the external pressure tank ball valve, and locked by the locking structure of the pressure tank ball valve.

[0024] By pushing the connector 2, the locking structure of the pressure tank ball valve can be pressed to loosen the locking of the water injection pipe 1, and the output end of the water injection pipe 1 can be separated from the pressure tank ball valve under the push of the elastic member 3.

[0025] In this design, the operator pushes the connector 2 towards the water injection pipe 1, causing the connector 2 to compress the spring. At this time, the output end of the water injection pipe 1 gradually passes through the connector 2. The purpose of letting the water injection pipe 1 pass through is to facilitate the connection between the output end of the water injection pipe 1 and the ball valve of the pressure tank. After the locking structure locks the water injection pipe 1, water injection can begin.

[0026] After water filling is completed, the operator only needs to push the connector 2 towards the pressure tank. By pressing the locking structure of the pressure tank ball valve through the connector 2, the locking of the water filling pipe 1 can be released. Under the push of the elastic element 3, the output end of the water filling pipe 1 is separated from the pressure tank ball valve. It is very convenient, and the structure is simple and economical.

[0027] Of course, the operator can also push the connector 2 to compress the spring and push the water injection pipe 1 directly toward the pressure tank ball valve, but this method requires precise alignment to insert the water injection pipe 1 into the pressure tank ball valve.

[0028] In this embodiment, the connector 2 includes an outer tube 21, and the outer tube 21 has an inner cavity 213 that matches the water injection pipe 1. The water injection pipe 1 is slidably connected in the inner cavity 213, and the elastic member 3 is located between the outer tube 21 and the water injection pipe 1.

[0029] Specifically, since this water injection device will be in a relatively humid environment for a long time, the connector 2 is set as an outer tube 21, which can protect the elastic element 3 inside the outer tube 21. At the same time, the water injection pipe 1 is slidably connected to the inner cavity 213, which can also provide a guiding function and ensure the stability of the translation of the water injection pipe 1.

[0030] In this embodiment, the elastic element 3 is preferably a spring.

[0031] Preferably, the outer pipe 21 has a through groove 214 on its side, and the water injection pipe 1 has a limiting member 11 that matches the through groove 214 on its side. The through groove 214 is used to restrict the limiting member 11 from sliding in the through groove 214.

[0032] In practical use, by using the through groove 214 and the limiting member 11, the outer tube 21 and the elastic member 3, and the water injection pipe 1 and the elastic member 3 can be connected in a non-fixed manner, which facilitates the maintenance of each component. Moreover, the through groove 214 can limit the movement distance of the limiting member 11 and prevent the water injection pipe 1 from detaching from the outer tube 21.

[0033] In this embodiment, the outer tube 21 includes a first tube body 211 and a second tube body 212 connected to one end of the first tube body 211. The first tube body 211 and the second tube body 212 are arranged coaxially. The diameter of the first tube body 211 is larger than the diameter of the second tube body 212. The first tube body 211 and the second tube body 212 together form the inner cavity 213. The elastic element 3 is located inside the first tube body 211.

[0034] Specifically, the first tube 211 adopts a tube with a larger diameter, which allows for the use of a spring with a larger diameter, resulting in better stability; implicitly, the water injection tube 1 matches the inner cavity 213, that is, the water injection tube 1 is also a stacked cylindrical structure, and the output end of the water injection tube 1 is the part with a smaller diameter.

[0035] In this embodiment, a recess 12 is provided on the outer side of the output end of the water injection pipe 1, and the recess 12 matches the sealing ring inside the pressure tank ball valve. Because the sealing ring is elastic, the recess 12 can improve the sealing performance without affecting the easy disassembly of the water injection pipe 1.

[0036] Preferably, a fixing plate 13 is provided on the input end of the water injection pipe 1, and a stud 14 is provided on the fixing plate 13. The stud 14 has a cavity that communicates with the water injection pipe 1, and a nut 15 is threadedly connected to the stud 14. The fixing plate 13 and the nut 15 are used to fix the water injection pipe 1 in the external hydrogen water station. The stud 14 is connected to the external hydrogen water delivery equipment 41 through a pipe connector.

[0037] When in use, first install the water injection pipe 1 in the designated position. Specifically, fix the water injection pipe 1 by clamping it with the nut 15 and the fixing plate 13. At this time, the stud 14 is still partially free. Then connect the stud 14 to the external delivery pipe through the pipe connector.

[0038] More preferably, both the outer pipe 21 and the water injection pipe 1 are made of stainless steel. Stainless steel has the advantages of high strength, resistance to deformation, and corrosion resistance, effectively resisting oxidation and corrosion, and is suitable for humid or corrosive environments.

[0039] Example 2

[0040] refer to Figures 3-4 A hydrogen water station includes an outer shell 4 and a hydrogen water station water injection device as described in Example 1 connected inside the outer shell 4. The outer shell 4 is provided with a hydrogen water delivery device 41 and a pressure tank placement platform 42. The water injection pipe 1 is connected to the hydrogen water delivery device 41.

[0041] Under this design, during installation, the stud 14 of the water injection pipe 1 is first inserted into the outer casing 4, and then fixed with the nut 15. Then, the water injection pipe 1 and the hydrogen water delivery equipment 41 are connected through the pipe connector, and the hydrogen water station can be started to inject water. The operator only needs to place the pressure tank on the pressure tank placement platform 42 and connect the pressure tank and the water injection pipe 1 to start the water injection.

[0042] By adding a connector 2 to the water injection pipe 1, and connecting the connector 2 to the water injection pipe 1 via an elastic element 3, when disassembly is required, the locking structure of the pressure tank ball valve can be pressed by pushing the connector 2 to loosen the locking of the water injection pipe 1, and the output end of the water injection pipe 1 can be separated from the pressure tank ball valve under the push of the elastic element 3. This is very convenient, and the structure is simple and economical.

[0043] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements or modifications can be made without departing from the principle of this application, and these improvements or modifications should also be considered within the scope of protection of this application.
