Description

Technical Field

[0001] This utility model relates to the field of water supply equipment technology, and in particular to a gas cylinder mounting component, a sparkling water machine, and an embedded water purifier. Background Technology

[0002] In water supply equipment with functional water supply capabilities, a gas cylinder corresponding to the functional water is typically installed. The functional water is generated using gas supplied from the cylinder. When the gas in the cylinder is depleted, it needs to be replaced. During replacement, the cylinder must be installed in conjunction with a pressure reducing valve inside the equipment to ensure a stable gas output.

[0003] However, in practice, because the pressure reducing valve is located inside the equipment, users cannot directly observe its exact position and status, leading to significant inconvenience in aligning the gas cylinder and the pressure reducing valve during installation. Specifically, when installing under non-visual conditions, ordinary users find it difficult to accurately determine the relative position of the gas cylinder's connection end and the pressure reducing valve's installation position. They often need to make multiple attempts to adjust the angle and position of the gas cylinder to complete the alignment, which not only takes a lot of time but also increases the difficulty of operation for the user.

[0004] Currently, existing equipment lacks auxiliary structures or designs specifically for the rapid alignment of gas cylinders and pressure reducing valves in non-visual environments. This makes the gas cylinder installation process overly reliant on user experience and feel, failing to meet the needs of ordinary users for quick and convenient installation. Therefore, how to achieve quick and accurate alignment and installation of gas cylinders and pressure reducing valves, and lower the user's operational threshold, has become a key issue in improving the user experience of this type of water supply equipment, and an effective solution is urgently needed.

[0031] The technical solution of this utility model has the following significant beneficial effects:

[0032] When a user needs to install a gas cylinder into the gas cylinder installation assembly and align it with the first air inlet of the pressure reducing valve, the guide portion has a guide protrusion with an end face. The user controls the gas cylinder to move the nozzle toward the first connecting port corresponding to the first air inlet. Even if the nozzle cannot directly and accurately enter the first connecting port, it will at least be against the end face. At this time, the user controls the nozzle to move radially on the end face, which allows the nozzle to enter the first connecting port more quickly. After that, since the first connecting port corresponds to the first air inlet, the user can control the nozzle to move toward the first air inlet, thus aligning the nozzle with the first air inlet for installation. Through the above structure of the gas cylinder installation assembly, the user can more conveniently and quickly align the gas cylinder nozzle with the first air inlet of the pressure reducing valve even when the user cannot directly observe it, significantly reducing the difficulty of operation and the time spent.

[0043] The details of this utility model can be more clearly understood by referring to the accompanying drawings and the description of specific embodiments. However, the specific embodiments of this utility model described herein are for illustrative purposes only and should not be construed as limiting the utility model in any way. Under the teachings of this utility model, those skilled in the art can conceive of any possible modifications based on this utility model, and these should all be considered to fall within the scope of this utility model.

[0044] To address the problem of users finding it inconvenient to align and install the gas cylinder with the pressure reducing valve, this application proposes a gas cylinder installation component. Figure 1 This is a schematic diagram of the structure of the gas cylinder and the pressure reducing valve in the gas cylinder mounting assembly after alignment and installation in this embodiment of the present invention. Figure 2 This is an exploded view of the gas cylinder mounting assembly in an embodiment of this utility model. Figure 3 This is a side view of the first bracket in an embodiment of the present invention. Figure 4 This is a three-dimensional structural diagram of the first support in an embodiment of the present invention. Figure 5 This is a bottom view of the gas cylinder mounting assembly in an embodiment of this utility model. Figure 6 This is a top view of the gas cylinder mounting assembly in an embodiment of the present invention, as shown below. Figures 1 to 6 As shown, the gas cylinder mounting assembly 201 may include: a pressure reducing valve 1 having a first air inlet 11; a fixing part 2 including a first bracket 21 and a second bracket 22, the first bracket 21 abutting against one end of the pressure reducing valve 1 and the second bracket 22 abutting against the other end of the pressure reducing valve 1, the first bracket 21 and the second bracket 22 being connected to each other to clamp the pressure reducing valve 1 inside for axial positioning; and a guide part 3 connected to the fixing part 2, the guide part 3 having a guide protrusion 31, the guide protrusion 31 having an end face 311, the end face 311 forming a first connecting port 312 corresponding to the first air inlet 11, the end face 311 being used to abut against the nozzle of the gas cylinder 202 and generate radial movement, so that the gas cylinder 202 can enter the first connecting port 312 and be aligned and installed with the first air inlet 11.

[0045] When the user needs to install the gas cylinder 202 into the gas cylinder installation assembly 201 and align it with the first air inlet 11 of the pressure reducing valve 1, the guide part 3 has a guide protrusion 31 with an end face 311. The user controls the gas cylinder 202 to move the nozzle toward the first connecting port 312 corresponding to the first air inlet 11. Even if the nozzle cannot directly and accurately enter the first connecting port 312, at least the nozzle will abut against the end face 311. At this time, the user controls the nozzle to move radially on the end face 311, which can quickly make the nozzle enter the first connecting port 312. After that, since the first connecting port 312 corresponds to the first air inlet 11, the user can control the nozzle to move toward the first air inlet 11 so that the nozzle is aligned and installed with the first air inlet 11. With the above-described structure of the gas cylinder mounting assembly 201, users can more conveniently and quickly align the nozzle of the gas cylinder 202 with the first air inlet 11 of the pressure reducing valve 1 even when they cannot directly observe the first air inlet 11 of the pressure reducing valve 1, greatly reducing the user's operational difficulty and the time spent.

[0046] To better understand the gas cylinder mounting assembly 201 in this application, it will be further explained and described below. For example... Figures 1 to 6 As shown, the gas cylinder mounting assembly 201 includes a pressure reducing valve 1, a fixing part 2, and a guide part 3. The pressure reducing valve 1 may have two opposing ends. The pressure reducing valve 1 has a first air inlet 11. Alternatively, the first air inlet 11 may be located on the side wall of the pressure reducing valve 1. The pressure reducing valve 1 may be generally cylindrical, for example. The first air inlet 11 may be located on the circumferential surface of the non-end face 311 of the pressure reducing valve 1. The first air inlet 11 of the pressure reducing valve 1 is used to connect with the nozzle of the gas cylinder 202, so that the gas output from the nozzle of the gas cylinder 202 enters the pressure reducing valve 1 for reduction.

[0047] like Figures 1 to 2 As shown, the fixing part 2 is used to limit the pressure reducing valve 1, such as supporting the pressure reducing valve 1 and limiting its axial (horizontal) and vertical directions. The fixing part 2 may include a first bracket 21 and a second bracket 22. The first bracket 21 is used to abut against one end of the pressure reducing valve 1, and the second bracket 22 is used to abut against the other end of the pressure reducing valve 1. The first bracket 21 and the second bracket 22 are connected to each other to clamp the pressure reducing valve 1 inside and limit its axial movement. In addition, the above method facilitates the installation of the pressure reducing valve 1 into the fixing part 2.

[0048] like Figure 2 and Figure 4As shown, the fixing part 2 is provided with a receiving groove 23, and the pressure reducing valve 1 is installed in the receiving groove 23. The first bracket 21 and the second bracket 22 are connected to each other to define the receiving groove 23. The first bracket 21 and the second bracket 22 are generally sleeve-shaped, and the openings of the first bracket 21 and the second bracket 22 face the pressure reducing valve 1 for fitting the pressure reducing valve 1. Further, the first bracket 21 and the second bracket 22 each include an abutment part 211 and a connecting part 212, and at least a portion of the connecting part 212 is arranged circumferentially along the abutment part 211 to form a sleeve shape.

[0049] Among them, such as Figure 2 As shown, the first bracket 21 has a first receiving portion corresponding to the shape of one end of the pressure reducing valve 1, and the second bracket 22 has a second receiving portion corresponding to the shape of the other end of the pressure reducing valve 1. One end of the pressure reducing valve 1 is disposed in the first receiving portion, and the other end of the pressure reducing valve 1 is disposed in the second receiving portion. The receiving groove 23 includes the first receiving portion and the second receiving portion. This structure limits the horizontal movement of the pressure reducing valve 1. When the cross-section of the pressure reducing valve 1 is approximately circular, the pressure reducing valve 1 can rotate at a certain angle in the circumferential direction within the fixing portion 2.

[0050] like Figures 1 to 2 As shown, the guide portion 3 can be connected to the fixing portion 2. For example, at least part of the guide protrusion 31 is integrally formed with the fixing portion 2. Alternatively, the guide portion 3 can be connected to the fixing portion 2 by other connection methods, such as insertion, snap-fit, or connection to the fixing portion 2 by other fasteners.

[0051] like Figure 2 As shown, the guide portion 3 has a guide protrusion 31. The fixing portion 2 has an axial direction, which is horizontal. The extension direction of the guide protrusion 31 is perpendicular to the axial direction of the fixing portion 2 and is vertical. The guide protrusion 31 has an end face 311. For example, the direction in which this end face 311 generally faces is opposite to the direction of movement of the gas cylinder 202 into the first air inlet 11 of the pressure reducing valve 1. The end face 311 forms a first connecting port 312 corresponding to the first air inlet 11. In the horizontal direction, at least a portion of the first connecting port 312 is provided around the first air inlet 11.

[0052] As a feasible option, such as Figure 2 and Figure 5 As shown, at least a portion of the guide protrusion 31 encloses and forms a first communication port 312. The first communication port 312 may be located in the central region of the guide protrusion 31 or in the edge region of the guide protrusion 31. The guide protrusion 31 may completely enclose and form the first communication port 312 or may partially enclose and form the first communication port 312.

[0053] When the user needs to install the gas cylinder 202 into the gas cylinder mounting assembly 201 and align it with the first air inlet 11 of the pressure reducing valve 1, the end face 311 is used to abut against the nozzle of the gas cylinder 202 and generate radial movement so that the gas cylinder 202 can enter the first communication port 312 and then be aligned and installed with the first air inlet 11.

[0054] In one feasible implementation, such as Figure 2 and Figure 5 As shown, the guide protrusion 31 may include a first guide protrusion 313 and a second guide protrusion 314. At least a portion of the first guide protrusion 313 is integrally formed with the first bracket 21. At least a portion of the second guide protrusion 314 is integrally formed with the second bracket 22. When the first bracket 21 and the second bracket 22 are connected to each other, at least a portion of the first guide protrusion 313 and at least a portion of the second guide protrusion 314 are spliced ​​together to form a first communication port 312.

[0055] As a feasible option, such as Figure 2 As shown, the pressure reducing valve 1 may have a first air outlet 12. The first air outlet 12 may be located on the circumference of the pressure reducing valve 1, and the air outlet passage of the first air outlet 12 is cross-connected with the air inlet passage of the first air inlet 11. That is, the position of the first air outlet 12 on the circumference of the pressure reducing valve 1 and the position of the first air inlet 11 on the circumference of the pressure reducing valve 1 are at different angles in the circumferential direction.

[0056] To facilitate the connection of the first outlet 12 of the pressure reducing valve 1 with other components, such as Figure 2 As shown, the fixing part 2 is also provided with a second connecting port 24 corresponding to the first air outlet 12.

[0057] As a feasible option, such as Figure 5 As shown, the pressure reducing valve 1 is also provided with an annular protrusion 13 around the outer periphery of the first air inlet 11, and at least part of the guide protrusion 31 is arranged around the annular protrusion 13. Both the annular protrusion 13 and the guide protrusion 31 are used to allow the gas cylinder 202 to slide, so that the gas cylinder 202 can slide into the annular protrusion 13 and be aligned with the first air inlet 11. With the above structure, in the direction in which the nozzle of the gas cylinder 202 moves into the first air inlet 11, the radial area of ​​the first connecting port 312 and the radial area inside the annular protrusion 13 gradually decrease, thereby playing a certain guiding role, making it easier for the user to move the nozzle of the gas cylinder 202 step by step to the position aligned with the first air inlet 11.

[0058] In order to enable the gas cylinder mounting assembly 201 to be installed on the sparkling water machine, as a feasible method is... Figure 2As shown, both the first bracket 21 and the second bracket 22 are provided with mounting protrusions 213, and the mounting protrusions 213 are provided with mounting holes for fixing to the housing 10 of the sparkling water machine. The mounting protrusions 213 can correspond to the mounting parts on the sparkling water machine, and then be fixedly connected to the mounting parts on the sparkling water machine through the mounting holes by fasteners such as screws.

[0059] This application also discloses a sparkling water machine, which includes a carbonation tank, a gas cylinder 202, and a gas cylinder mounting assembly 201 for any of the above. The carbonation tank is used to form and store sparkling water. The carbonation tank has a second air inlet connected to a first air outlet 12. The gas cylinder 202 has a second air outlet connected to a first air inlet 11. Carbon dioxide gas output from the gas cylinder 202 is depressurized at the first air inlet 11 of the pressure reducing valve 1 and can then be input to the second air inlet of the carbonation tank through the first air outlet 12, thus entering the carbonation tank. The carbonation tank may also have a water inlet for replenishing water into the carbonation tank.

[0060] This application also proposes an embedded water purifier. Figure 7 This is a front view of the embedded water purifier in an embodiment of this utility model, as shown below. Figure 7 As shown, it includes: a housing 10, the housing 10 including a front panel 101, the front panel 101 having a mounting groove 102; a sparkling water assembly, the sparkling water assembly being used to prepare sparkling water, the sparkling water assembly including a gas cylinder 202 and a gas cylinder mounting assembly 201 as described above, the gas cylinder 202 being disposed in the mounting groove 102.

[0061] Alternatively, the mounting slot 102 can be located on the left or right side of the front panel 101. A water outlet control mechanism 40, such as a faucet, can be provided in the center of the front panel 101. A filter element can be provided on the other side of the front panel 101 opposite to the mounting slot 102. The filter element can be installed in the housing 10 in a pluggable or rotatable manner.

[0062] Alternatively, the front panel 101 may cover the gas cylinder mounting assembly 201. The gas cylinder 202 needs to be at least partially inserted into the mounting slot 102 and then moved upward to align with the first air inlet 11 of the pressure reducing valve 1 of the gas cylinder mounting assembly 201.

[0063] As an option, a rubber component 30 is provided between the bottom of the gas cylinder 202 and the mounting groove 102, so that the gas cylinder 202 can be securely installed in the mounting groove 102, and the lower end of the gas cylinder 202 is pressed against the bottom wall of the mounting groove 102.

[0064] As feasible, the pressure reducing valve 1 can rotate about its axis relative to the fixed part 2. The pressure reducing valve 1 has a first position and a second position. In the first position, the first air inlet 11 of the pressure reducing valve 1 faces downward; in the second position, the first air inlet 11 of the pressure reducing valve 1 faces the front panel 101 at an angle to the vertical direction. When it is necessary to remove the gas cylinder 202 or install a new gas cylinder 202, the pressure reducing valve 1 is first rotated to the second position, which facilitates the removal of the gas cylinder 202 from the pressure reducing valve 1 and its alignment and installation. After the gas cylinder 202 is aligned and installed with the pressure reducing valve 1, the gas cylinder 202 is rotated to make the pressure reducing valve 1 rotate together, thereby changing from the second position to the first position, and then fully installed in the mounting groove 102.
