Description

Technical Field

[0001] The present application relates to the technical field of water production and utilization equipment, and in particular to a water injection device for a hydrogen-rich water station. Background Art

[0002] Hydrogen-rich water is water containing trace amounts of hydrogen molecules. Since hydrogen-rich water requires a mixture of hydrogen and water, hydrogen-rich water stations are different from ordinary community water vending machines, and accordingly, the water bucket structure used is also different.

[0003] The hydrogen-rich water bucket can withstand a certain amount of pressure. When filling, the water pipe from the hydrogen-rich water station is inserted into the water inlet of the hydrogen-rich water bucket's drain valve, and the hydrogen-rich water is filled into the bucket by applying pressure. During the filling process, the pressure inside the hydrogen-rich water bucket will also squeeze the water pipe of the hydrogen-rich water station outward. Therefore, the water inlet of the hydrogen-rich water bucket's drain valve has a locking structure to lock the inserted water pipe, thereby reducing the possibility of the water pipe being ejected by the pressure inside the hydrogen-rich water bucket.

[0004] However, due to the locking mechanism, removing the water pipe after filling is completed is very laborious. This makes it easy for hands to come into contact with the hydrogen water station's pipe, causing bacteria to grow and adversely affecting the user's health. While replacing it with a metal pipe would solve the problem of difficult removal, the locking mechanism makes it difficult to tighten the metal pipe, reducing its seal and potentially causing it to fly away due to the pressure inside the hydrogen water tank, compromising safety.

[0005] Therefore, it is necessary to design a hydrogen-rich water station water filling structure that can improve the water pipe connection strength during water filling and can also facilitate the removal of the water pipe after the water filling is completed. Summary of the Invention

[0006] The purpose of the invention proposed in this application is to improve the problem that the existing hydrogen-rich water station water injection structure is difficult and unhygienic to pull out after the water injection is completed. This application provides a hydrogen-rich water station water injection device.

[0007] The present application provides a hydrogen-rich water station water injection device that adopts the following technical solutions:

[0008] A water injection device for a hydrogen-rich water station, comprising

[0009] The water station body includes a water tank for placing water buckets for filling water. A pressure hole is opened on the top of the water tank of the water station body;

[0010] The downward pressure device is installed on the water station body and can be a device with downward pressure function such as a telescopic cylinder;

[0011] The water injection pipe is made of metal material and is connected to the water pipe at the top;

[0012] The middle shell is installed on the water injection pipe, and the inner wall of the middle shell and the water injection pipe form a cylindrical active cavity;

[0013] The piston cylinder is slidably connected to the bottom of the water injection pipe and is partially located in the movable cavity;

[0014] A first ring plate is fixed to the bottom end of the middle shell, a second ring plate is fixed to the top end of the piston cylinder, and an ejection spring is installed on the top wall of the movable cavity. The other end of the ejection spring presses against the second ring plate, so that the second ring plate presses against the first ring plate. At this time, the bottom end of the piston cylinder is flush with the bottom end of the water injection pipe.

[0015] The middle shell is arranged on the top of the water filling tank of the water station body. The downward pressure device is used to drive the middle shell to move downward and reset. The middle shell part passes through the downward pressure hole.

[0016] When the water is poured into the water tank, the piston cylinder is retracted to release the water supply pipe, and the piston cylinder is retracted to release the water supply pipe, thereby effectively reducing the risk of the bottom end of the water supply pipe being touched by human hands and improving hygiene. At the same time, due to the driving of the downward pressure device and the resetting protection of the piston cylinder, the probability of the metal water supply pipe being ejected is effectively reduced, thereby improving safety and improving the firmness of the connection with the water supply pipe of the hydrogen-rich water tank during water filling.

[0017] Optionally, a correction cover is installed at the bottom of the circumferential outer wall of the piston cylinder. The correction cover is trumpet-shaped, and the bottom inner wall is tilted excessively toward the bottom end of the water injection pipe.

[0018] By adopting the above technical solution, the setting of the correction cover can improve the efficiency of the connection between the water injection pipe and the water injection port of the hydrogen-rich water bucket during the downward movement of the middle shell.

[0019] Optionally, the correction cover is threadedly connected to the bottom of the circumferential outer wall of the piston cylinder.

[0020] By adopting the above technical solution, the installation of the correction cover can effectively realize the disassembly and replacement of the piston cylinder, and the setting of the ejection spring can also keep the piston cylinder in the ejected state when the correction cover is installed and disassembled.

[0021] Optionally, the top protrusion of the circumferential outer wall of the water injection pipe is a mounting portion, the bottom of the mounting portion is threaded, and the circumferential inner wall at the top of the middle shell is threadedly connected to the threaded part of the mounting portion.

[0022] By adopting the above technical solution, the installation arrangement of the water injection pipe effectively realizes the detachable installation of various parts of the water injection device, that is, the piston cylinder and the ejection spring are first placed in the middle shell and then the middle shell is threadedly connected and installed with the installation part for combined fixing.

[0023] Optionally, a mounting ring plate is fixedly provided on the top of the mounting portion, and a downward pressure ring piece is sleeved between the mounting ring plate and the middle shell. The downward pressure device is connected to the downward pressure ring piece to drive the middle shell to move downward.

[0024] By adopting the above technical solution, the space between the installation setting of the middle shell and the installation ring plate is just sufficient for the installation of the down-pressing ring sheet. At the same time, the down-pressing ring sheet and the down-pressing device are also installed, thereby realizing the detachable installation of the water injection device and the down-pressing device.

[0025] Optionally, the pressing device includes an upper pressing cylinder, a bottom plate and a lower pressing plate;

[0026] The piston rod of the upper pressure cylinder is upward, and the bottom end is rotated and connected to the outer wall of the water filling tank of the water station body;

[0027] The bottom plate is installed on the upper surface of the water tank of the water station body, and the middle part is raised upward and rotatably connected to the lower pressure plate;

[0028] One end of the lower pressure plate is rotatably connected to the piston rod of the upper pressure cylinder, and the other end is rotatably connected to the lower pressure ring piece.

[0029] By adopting the above technical solution, the upper pressure cylinder can drive the lower pressure plate to rotate, and then press the middle shell downward through the lower pressure ring. At the same time, it can also make the middle shell rotate relative to the lower pressure plate, thereby improving the stability of driving the middle shell downward and resetting.

[0030] Optionally, a stabilizing cylinder is fixedly provided in the lower pressure hole, and the inner diameter of the stabilizing cylinder is larger than the outer diameter of the middle shell;

[0031] When the middle shell is located at the lowest position, the middle shell abuts against the inner wall of the stabilizing cylinder.

[0032] By adopting the above technical solution, the setting of the stabilizing cylinder effectively supports the middle shell when the water injection pipe is connected to the water injection port, thereby improving the stability of the position of the middle shell at this time.

[0033] Optionally, the lower pressing plate is provided with an arc-shaped groove abutting against the middle shell.

[0034] By adopting the above technical solution, the arc groove setting of the lower pressure plate can effectively fit the contour of the middle shell, thereby providing a support point for the middle shell during the rotation process, thereby improving the stability of the middle shell during the downward movement and reset process.

[0035] In summary, this application includes at least one of the following beneficial technical effects:

[0036] The middle shell and the water injection pipe move downward together. After the water injection port of the hydrogen-rich water bucket contacts the piston cylinder, the piston cylinder is pushed upward. Then the water injection pipe is connected to the water injection port, maintaining the downward pressure to inject water into the hydrogen-rich water bucket, thereby improving the stability of water injection. At the same time, after the water injection is completed, the water injection pipe can be stably moved upward under the drive of the downward pressure device. The piston cylinder is reset under the action of the ejection spring to push the water injection port of the hydrogen-rich water bucket outward, thereby improving the efficiency of separating the water injection port of the hydrogen-rich water bucket from the water injection pipe.

[0037] The end of the water injection port is wrapped by the piston cylinder when not connected, which effectively reduces the probability of the water injection pipe contacting the outside world and does not require manual touch, thereby improving hygiene. At the same time, after the water injection pipe is separated from the water injection port, it can be immediately placed in the piston cylinder, reducing the probability of the water injection pipe being bounced off by high-pressure gas and improving safety.

[0038] The threaded connection arrangement of each part of the water injection device enables each part of the water injection device to be disassembled and replaced independently, thereby improving the efficiency of disassembly and assembly and reducing maintenance costs.

DETAILED DESCRIPTION

[0045] The following is combined with Figure 1-5 This application is described in further detail.

[0046] The embodiment of the present application discloses a water injection device for a hydrogen-rich water station.

[0047] refer to Figure 1 and Figure 2 The hydrogen-rich water station water injection device includes a water station body 1, a water injection pipe 2, a middle shell 3, a piston cylinder 4 and a pressure device 5. The water station body 1 contains a water filling tank for placing a water bucket for filling water, and a pressure hole 11 is opened on the top of the water filling tank of the water station body 1.

[0048] Combine Figure 2 and Figure 3 The water injection pipe 2 is made of metal and is connected to the water pipe at the top. The top of the circumferential outer wall of the water injection pipe 2 is a protrusion forming a mounting portion 21. The bottom of the mounting portion 21 is threaded, and a mounting ring plate 22 is fixed to the top of the mounting portion 21. The circumferential outer wall of the top of the middle shell 3 is threadedly connected to the threaded portion of the mounting portion 21. The inner wall of the middle shell 3 and the circumferential outer wall of the water injection pipe 2 form a cylindrical movable chamber 31. The piston cylinder 4 is sleeved on the bottom of the water injection pipe 2 and is slidably connected to the water injection pipe 2. A second ring plate 41 is fixed to the top of the piston cylinder 4, which abuts the inner wall of the middle shell 3. A first ring plate 32 is fixed to the bottom of the middle shell 3, which abuts the circumferential outer wall of the piston cylinder 4. An ejection spring 311 is installed on the top wall of the movable chamber 31. The other end of the ejection spring 311 presses against the second ring plate 41, so that the second ring plate 41 presses against the first ring plate 32. At this time, the bottom end of the piston cylinder 4 is flush with the bottom end of the water injection pipe 2. A correction cover 42 is threadedly connected to the bottom of the circumferential outer wall of the piston cylinder 4. The correction cover 42 is made of metal and is trumpet-shaped. The inner wall of the bottom of the correction cover 42 is tilted excessively toward the bottom end of the water injection pipe 2. A downward pressure ring 531 is sleeved between the top of the middle shell 3 and the mounting ring plate 22. The downward pressure ring 531 is provided with a rotating shaft at both ends. The downward pressure device 5 is installed in the water station body 1 and can be a device or mechanical component with a downward pressure function, such as a telescopic cylinder. It is connected to the downward pressure ring 531 and is used to drive the middle shell 3 to move downward through the downward pressure hole 11.

[0049] Combine Figure 3 and Figure 4 When water filling is required, the hydrogen-rich water bucket is placed in the water filling tank of the water station body 1. The downward pressure device 5 drives the middle shell 3 and the water injection pipe 2 to move downward together through the downward pressure ring 531. During the downward movement, the correction cover 42 first abuts against the water injection port of the hydrogen-rich water bucket and moves the water injection port toward the center of the correction cover 42 through the inclined surface, thereby improving the stability of the water injection pipe 2 inserted into the water injection port. Subsequently, the water injection port abuts against the end of the piston cylinder 4 and pushes the piston cylinder 4 into the movable chamber 31, so that the water injection pipe 2 leaks out and is inserted into the water injection port of the hydrogen-rich water bucket for water filling. During this process, the downward pressure device 5 keeps the water injection pipe 2 in its current position. The metal material of the water injection pipe 2 effectively improves the efficiency of insertion and removal in the water injection port. At the same time, under the pressure of the downward pressure device 5, the probability of being bounced off during the water filling process is reduced, thereby improving safety.

[0050] On the other hand, since the bottom of the water injection pipe 2 is wrapped by the piston cylinder 4 before water injection, the probability of the bottom of the water injection pipe 2 coming into contact with the outside world is effectively reduced, thereby improving hygiene. The arrangement of the middle shell 3 and the ejection spring 311 allows the bottom of the water injection pipe 2 to be released only after it is aligned with the water injection port, thereby improving the effectiveness of the water injection connection. At the same time, after the water injection is completed, the piston cylinder 4 can quickly return to wrap the bottom of the water injection pipe 2, further improving the safety of the hydrogen-rich water injection.

[0051] Combine Figure 5 The threaded connection between the piston cylinder 4 and the correction cover 42 enables the replacement of the correction cover 42. At the same time, in conjunction with the threaded installation of the middle shell 3, the various parts can be assembled. That is, the piston cylinder 4 is first inserted into the middle shell 3, and then the ejection spring 311 is placed into the middle shell 3. The water injection pipe 2 is then inserted and threadedly connected to the middle shell 3 for installation. At the same time, the lower pressure ring 531 is clamped between the installation ring plate 22 and the middle shell 3, and finally the correction cover 42 is installed. This improves the installation efficiency of the water injection device, facilitates the replacement and maintenance of parts in the later stage, and reduces maintenance costs.

[0052] refer to Figure 3 The down-pressing device 5 includes an upper pressure cylinder 51, a bottom plate 52 and a lower pressure plate 53. The piston rod of the upper pressure cylinder 51 is upward, and the bottom end is rotatably connected to the outer wall on the back of the water tank of the water station body 1. The bottom plate 52 is installed on the upper surface of the water tank of the water station body 1, and the middle part is raised upward and rotatably connected to the lower pressure plate 53. One end of the lower pressure plate 53 is rotatably connected to the piston rod of the upper pressure cylinder 51, and the other end is rotatably connected to the lower pressure ring 531. An arc-shaped groove 532 for abutting against the circumferential outer wall of the middle shell 3 is provided at one end of the lower pressure plate 533 close to the lower pressure ring 531. A stabilizing cylinder 111 is fixed to the down-pressing hole 11, and the inner diameter of the stabilizing cylinder 111 is larger than the outer diameter of the middle shell 3. When the middle shell 3 is at the lowest position, the middle shell 3 abuts against the inner wall of the stabilizing cylinder 111.

[0053] When filling the hydrogen-rich water tank, the piston rod of the upper pressure cylinder 51 extends and drives the lower pressure plate 53 to rotate, thereby pressing the middle shell 3 and the water injection pipe 2 downward together through the lower pressure ring 531, while also allowing the middle shell 3 to rotate appropriately relative to the lower pressure plate 53. The provision of the arcuate groove 532 provides a support point for the middle shell 3, improving the stability of the middle shell 3 during the downward pressure process. The provision of the stabilizing cylinder 111 also improves the stability of the water injection pipe 2 during water injection, thereby enhancing the safety of filling the hydrogen-rich water tank.

[0054] The implementation principle of the water injection device of a hydrogen-rich water station in the embodiment of the present application is as follows: the upper pressure cylinder 51 drives the lower pressure plate 53 to rotate so that the middle shell 3 and the water injection pipe 2 move downward together. During the downward movement, the correction cover 42 abuts against the water injection port of the hydrogen-rich water bucket and drives the water injection port to move toward the bottom end of the water injection pipe 2. After abutting against the piston cylinder 4, it drives the piston cylinder 4 to move into the movable chamber 31, so that the water injection pipe 2 is inserted into the water injection port for water injection. After the water injection is completed, the water injection pipe 2 is reset, and the piston cylinder 4 pops out to re-wrap the water injection pipe 2, effectively reducing the probability of human hands touching the water injection pipe 2 and improving the hygiene of the water injection pipe 2. At the same time, the reset pressure of the piston cylinder 4 effectively improves the efficiency of pulling out the water injection pipe 2 and reduces the probability of the water injection pipe 2 flying after pulling out, thereby improving the safety of the hydrogen-rich water bucket when filling water.

[0055] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
