The base is installed above the refrigeration mounting bracket and the water fitting mounting bracket, while the side stand is located on the side of the base near the filter mounting bracket. The side stand separates the two water tanks from other modules located in the front area of ​​the water tanks.

[0011] To better accommodate the different structural requirements of the raw water tank and the purified water tank, the base of the water storage tank seat is equipped with interfaces for connecting to the raw water tank and the purified water tank. The base plate heights of the areas where the raw water tank and the purified water tank are placed are different, with the base height corresponding to the purified water tank area being lower than that corresponding to the raw water tank area.

[0012] Furthermore, the water fitting mounting bracket is equipped with a partition plate that divides the interior of the water fitting mounting bracket into an upper mounting space and a lower mounting space. The water circuit components include a power motor for providing power for raw water filtration and a water distribution valve assembly for distributing filtered purified water. The power motor and the water distribution valve assembly are installed in different mounting spaces.

[0013] Furthermore, the power motor is installed in the lower mounting space of the water fitting mounting frame, and the water distribution transfer valve assembly is installed in the upper mounting space of the water fitting mounting frame; the top of the power motor is detachably connected to the partition plate in the water fitting mounting frame through a connecting plate, and the bottom of the lower mounting space is provided with an opening for the power motor to be placed and removed.

[0014] Furthermore, the refrigeration mounting rack and the water fitting mounting rack share at least part of the mounting frame, and there are partitions on the relatively close walls of the two, which separate the installation spaces on both sides.

[0015] Furthermore, the water fitting mounting rack has at least one opening on its four sides as an inspection window; the refrigeration mounting rack has an air inlet channel at its bottom and an air outlet channel on at least one side of its wall.

[0016] Furthermore, the water purifier also includes a base, and the main frame inside the water purifier is detachably connected to the base.

[0017] 3. Beneficial effects

[0018] Compared with the prior art, the technical solution provided by this invention has the following advantages:

[0019] (1) The multifunctional water purifier of the present invention has the functions of making room temperature water, hot water and cold water. The filter module is located in the center and other components are arranged around the filter module as the axis. The upper rear side is set as the water tank area, the lower rear side is set as the cooling area and water component area, and the front is set as the water receiving area. The functional components in each area are arranged in a compact and reasonable manner, and each functional module is safely separated, which is conducive to promoting the miniaturization and integration of the whole machine. Moreover, the position of each operating area conforms to the user's usage habits, which is conducive to improving the user's operating convenience.

[0020] (2) The multifunctional water purifier of the present invention, by setting up a main frame and dividing the main frame into different installation spaces, installs all internal functional modules on the main frame. After the installation of each functional module, the performance of the whole machine can be tested directly. It has sufficient external space for maintenance.

[0027] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings.

[0028] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] The present invention will be further described below with reference to embodiments.

[0030] Example 1

[0031] Combination Figures 1-7 As shown, the countertop multi-functional water purifier of this embodiment includes a main frame, which divides the interior of the water purifier into a filter area, a water tank area, a cooling area, a water fitting area, and a water receiving area. The filter area is located in the middle of the main frame, and a filter module 903 is installed in the filter area. The upper rear side of the filter module 903 is the water tank area, in which a raw water tank 1 and a purified water tank 2 are arranged side by side along the left and right width direction. The lower rear side of the filter module 903 has a cooling area and a water fitting area arranged side by side along the left and right width direction. A cooling module 8 is installed in the cooling area for preparing cold water. Water fitting components are installed in the water fitting area. A heating element for heating the filtered purified water is also provided on one side of the filter module 903 in the width direction. When the heating element is activated, it heats the purified water to the corresponding temperature to prepare hot water. When room temperature water is needed, the heating element is not activated. The front of the filter module 903 is a water receiving area, which includes a water tap 7. The water outlets of the refrigeration module 8 and the heating element are both connected to the water tap 7. Specifically, the water tap 7 has two inlets: a cold water inlet and a hot water inlet, with the hot water inlet also serving as a room temperature water inlet. This layout allows for independent separation of each functional module, facilitating their installation and maintenance. The components are also compactly distributed, effectively saving internal space and promoting the miniaturization of the entire unit. Furthermore, the distribution of each module largely conforms to user operating habits, offering high ease of use.

[0032] To further enrich the functions of the water purifier, an air pumping area is also provided inside the main frame. The air pumping area is equipped with an air pumping module for preparing sparkling water. The air pumping module is distributed on the opposite side of the filter module 903 in the width direction, opposite to the heating element, so that the various functional components of the water purifier are arranged compactly and tightly surrounded by the filter module 903 as the axis.

[0033] As a practical design feature, to facilitate users in easily cleaning or adding water to the tanks, both the raw water tank 1 and the purified water tank 2 are detachably connected to the main frame. Furthermore, the raw water tank 1 and purified water tank 2 are distributed from right to left along the width direction on the upper rear side of the filter module 903, with the raw water tank 1, which is accessed more frequently, located on the right side, better aligning with user habits. Similarly, a more optimized design places the air pump module on the right side of the filter module 903 along its width direction, making it easier for users to disassemble and replace the gas cylinder when it runs out of gas.

[0034] In this embodiment, the main frame has multiple mounting brackets, including a filter element mounting bracket for mounting the filter element module 903 in the filter element area, a water storage tank seat 3 on the upper rear side of the filter element mounting bracket, a refrigeration mounting bracket 110 and a power mounting bracket 401 arranged side by side on the lower rear side of the filter element mounting bracket, wherein the water storage tank seat 3 is installed above the refrigeration mounting bracket 110 and the power mounting bracket 401 respectively, and the raw water tank 1 and the purified water tank 2 are respectively arranged on the water storage tank seat 3.

[0035] As a preferred option for the water storage tank base 3, such as Figure 5 As shown, the water tank base 3 includes an L-shaped base and a side stand. The base is installed above the refrigeration mounting bracket 110 and the power mounting bracket 401, while the side stand is located on the side of the base near the filter mounting bracket. The side stand separates the two water tanks from other modules located in the front area of ​​the water tanks to prevent accidental water leakage from affecting other components.

[0036] In this embodiment, the capacity of the raw water tank 1 is larger than that of the purified water tank 2 to meet the filtration and water supply requirements. In order to facilitate users to directly place the purified water tank 2 into the refrigerator to quickly prepare cold water, the purified water tank 2 is set to be large enough to fit into the side wall of the refrigerator door. Its width is smaller than that of the raw water tank 1, but its depth is larger than that of the raw water tank 1. Correspondingly, the base of the water storage tank seat 3 is provided with an interface for connecting with the raw water tank 1 and the purified water tank 2. The base plate heights of the areas where the raw water tank 1 and the purified water tank 2 are placed are different. The base height corresponding to the area where the purified water tank 2 is placed is lower than the base height corresponding to the area where the raw water tank 1 is placed, so that the tops of the two water tanks remain flush.

[0037] To achieve separate installation of water circuit components, as a preferred design in practice, the power mounting bracket 401 is equipped with a partition plate, dividing the interior of the power mounting bracket 401 into an upper installation space and a lower installation space. The water circuit components include a filter element power pump 400 for providing power for raw water filtration, and a water distribution transfer valve assembly 800 for distributing filtered purified water. The filter element power pump 400 and the water distribution transfer valve assembly 800 are installed in different installation spaces. The filter element power pump 400 is used to pump raw water from the raw water tank 1 into the filter element for filtration, while the water distribution transfer valve assembly 800 is used to distribute the filtered purified water, causing it to flow to the purified water tank 2 for storage, to the refrigeration module 8 to prepare cold water, and to the heating element pipeline to prepare hot water and room temperature water. As a preferred design, the filter cartridge power pump 400 is installed in the lower mounting space within the power mounting bracket 401, and the water distribution transfer valve assembly 800 is installed in the upper mounting space within the power mounting bracket 401. The top of the filter cartridge power pump 400 is detachably connected to the upper partition base plate via a connecting plate, and the bottom of the lower mounting space has an opening for the filter cartridge power pump 400 to be placed and removed vertically. This design enables the filter cartridge power pump 400 to be installed upside down, allowing it to be directly placed and removed within the lower mounting space, with the bottom of the filter cartridge power pump 400 suspended in the air. The upper part is mounted on the partition base plate 402 via the connecting plate, preventing contact with the base of the machine or other functional modules. This effectively reduces the transmission of motor vibration to other functional components, ensuring stable operation of all functional components and guaranteeing noise reduction and stability during long-term use of the water purifier.

[0038] As an optimized design for the refrigeration mounting bracket 110 and the power mounting bracket 401, to save space and materials, the refrigeration mounting bracket 110 and the power mounting bracket 401 share at least a portion of the mounting frame. A partition plate A4015 is provided on the relatively close wall surfaces of both, separating the filter element power pump 400 from the refrigeration module 8, further ensuring the safe separation of the water circuit from other components and effectively enhancing the structural stability of the mounting bracket. A further optimized design includes at least one opening on the wall surface of the power mounting bracket 401 as a maintenance window for convenient performance testing of the filter element power pump 400; an air inlet channel is provided at the bottom of the refrigeration mounting bracket 110, and an air outlet channel is provided on at least one side wall, specifically an air outlet channel on the rear side of the refrigeration mounting bracket 110, to provide heat dissipation space for the internal refrigeration module 8.

[0039] To facilitate the installation and maintenance of the water purifier, this embodiment uses a detachable connection between the main frame and the base 5 of the water purifier, and installs each functional module on the main frame. This allows for functional testing of each component after installation, ensuring proper functioning before installing the outer casing and base 5. This avoids repeated disassembly and reassembly during maintenance, improving installation and maintenance efficiency.

[0040] Example 2

[0041] To more clearly demonstrate the overall structural design of the water purifier in this application, the specific module structural design of each area is described below. First, the structure of the raw water tank 1 in this application is described. This raw water tank 1 is mainly used in household water purifiers, but it can also be used in industrial water purifiers. The raw water tank 1 can be fixedly installed in the water purifier, or it can adopt a movable structure that can be removed from the water purifier. This embodiment takes a household water purifier as an example, and the raw water tank 1 adopts a movable and removable independent structural form.

[0042] like Figures 8 to 15 As shown, the raw water tank 1 provided in this embodiment includes a raw water zone 16 for storing raw water and a concentrated water zone 17 for storing the concentrated water produced after purification by the filtration device. Of course, the raw water zone 16 and the concentrated water zone 17 can adopt an integrated structure, that is, a whole raw water tank 1 is divided into two areas, or they can be two independent and separate tanks; in this embodiment, an integrated structure is adopted, which is formed by dividing the water storage space of the raw water tank 1 into two independent chambers by a partition plate 18.

[0043] The bottom of the raw water zone 16 is provided with a raw water outlet 151 that connects to the filter device of the water purifier. The raw water outlet 151 is used to connect the raw water zone 16 to the filter device. The bottom of the concentrated water zone 17 is provided with a concentrated water inlet 152 that connects the concentrated water zone 17 to the filter device. A separate raw water tank 1 is adopted. When installed on the water purifier, check valves are installed at the raw water outlet 151 and the concentrated water inlet 152. When the raw water tank 1 is removed from the water purifier, the raw water outlet 151 and the concentrated water inlet 152 will be automatically closed to prevent water from flowing out of the tank.

[0044] In this embodiment, the raw water tank 1 is also specially equipped with a return channel to connect the raw water zone 16 and the concentrated water zone 17. This channel is used to return the concentrated water in the concentrated water zone 17 to the raw water zone 16 after it reaches a certain height. The return channel plays a role in regulating the raw water recovery rate of the raw water tank 1. According to actual usage needs, return channels of different heights can be set. When the concentrated water collected in the concentrated water zone 17 reaches the return height, the water in the concentrated water zone 17 can be returned to the raw water zone 16 for reuse. The return channel can be implemented in various ways, such as by pipes, opening connecting holes, opening connecting grooves, or even directly designing the shape of the partition plate 18 between the concentrated water zone 17 and the raw water zone 16. In order to realize the return of raw water, the return height of the return channel is lower than the maximum water storage height of the concentrated water zone 17 and the raw water zone 16. For example, the return height of the return channel can be 1 / 3, 1 / 2, or 2 / 3 of the corresponding maximum water storage height, etc., with preference given to exceeding 1 / 2 of the water storage height.

[0045] Combination Figure 8 and Figure 12 As shown, in this embodiment, the return channel is implemented by opening a return port 131 on the partition plate 18. After the raw water storage device is full, the water level can be continuously lowered to the height of the return port 131 through use, thus separating the concentrate zone 17 and the raw water zone 16. The water in the concentrate zone 17 rises above the height of the return port 131 due to the concentrated water filtered by the filter element, and can then overflow back to the raw water zone 16 for reuse. Alternatively, if the initial raw water level in the raw water zone 16 is lower than the return port 131, the concentrate zone 17 will be empty, and the water storage utilization rate of the storage device will be relatively low. Of course, a return hole can also be provided on the upper side of the partition plate 18 to form a return channel. The return port 131 can be a notch opened on the partition plate 18, and the return hole can be a through hole opened in the partition plate 18. Or, as Figure 13 As shown, the upper side of the partition plate 18 is directly made into an inclined side, and a return channel is formed at the lowest point of the inclined side. When the water in the concentrate zone 17 is higher than the lowest point of the inclined side, a return flow occurs. Based on the addition of a return port 131 or return hole on the partition plate 18, the height of the return port 131 or return hole on the partition plate 18 can be made adjustable. By adjusting the height of the return port 131 or return hole, the return height can be changed, and the raw water recovery rate can be adjusted as needed. Alternatively, the partition plate 18 can be detachably connected to the water tank wall via a plug-in connection, allowing for adjustment of the raw water recovery rate by directly plugging in partition plates 18 of different heights.

[0046] Special design is required, such as Figure 10 As shown, viewed from above (top view) of the raw water tank 1, the concentrate inlet 152 is located at the bottom of the concentrate zone 17, away from the connection point between the return channel and the concentrate zone 17. From the perspective of the attached diagram, the return channel is located near the rear side of the tank, and the concentrate inlet 152 is located near the front side of the tank. This design connects the concentrated water zone 17 and the raw water zone 16 at a certain height via a return channel. The concentrated water produced by the water purifier's filtration device enters the concentrated water zone 17 and is stored to a certain height before overflowing into the raw water zone 16 through the return channel. On the one hand, the concentrated water can undergo settling in the concentrated water zone 17, with dirtier sludge settling to the bottom, while the upper layer of water is relatively clean and can be returned to the raw water zone 16 for reuse, thus improving water utilization. On the other hand, the concentrated water inlet 152 of the concentrated water zone 17 is set relatively far from the return channel, increasing the settling time of the concentrated water returning to the raw water zone 16 through the return channel and reducing the impact of water flow agitation near the concentrated water inlet 152, further improving the water quality of the water returning to the raw water zone 16, reducing the filtration burden to some extent, and extending the life of the filtration device.

[0047] In this embodiment, the raw water zone 16 and concentrated water zone 17 of the water purifier's raw water tank 1 are an integrated tank separated by an internal partition plate 18 extending in the front-to-back direction. The structure is simple and easy to implement; for example, it can be formed in one piece by plastic injection molding or metal casting, preferably injection molding. When the raw water tank 1 of the water purifier is an integrated tank, the cross-section of the tank can be of any shape, such as circular, rectangular, square, or other irregular shapes. The return channel can be located on the partition plate 18 near the raw water rear tank plate 12, and the concentrated water inlet 152 is located on the raw water tank bottom plate 15, near the raw water front tank plate 11. That is, the concentrated water inlet 152 and the return channel are as far apart in the front-to-back direction as possible to achieve the best return water quality effect. More preferably, the raw water outlet 151 is located on the raw water tank bottom plate 15, near the raw water front tank plate 11, so that the water in the raw water zone 16 can reach the raw water outlet 151 with the greatest possible settling distance. Ideally, the concentrate inlet 152 and the raw water outlet 151 should be located at the edge of the raw water front tank plate 11. However, considering various requirements such as actual processing and installation space, this ideal state cannot be achieved in practice. In actual design, they should be as close as possible to the raw water front tank plate 11 without affecting the process.

[0048] In this embodiment, preferably, the water tank has a rectangular barrel-shaped structure, meaning its cross-section is rectangular. It is enclosed by a front raw water tank panel 11, a rear raw water tank panel 12, a left raw water tank panel 13, a right raw water tank panel 14, and a bottom raw water tank panel 15. The partition plate 18 is a flat plate extending to the front and rear raw water tank panels 11 and 12 respectively in the front-to-back direction. Further considering the raw water utilization and recovery rate, the volume of the raw water zone 16 formed by the partition plate 18 is larger than the volume of the concentrated water zone 17. For example, if the partition plate 18 is located at 2 / 3 of its position in the left-to-right direction, the volume of the raw water zone 16 is set to be twice that of the concentrated water zone 17. Of course, other volume ratios are also possible. The raw water tank 1 is divided into the concentrated water zone 17 and the raw water zone 16 on the left and right sides from the front-to-back direction of its installation on the water purifier, and the volume ratio of the raw water zone 16 and the concentrated water zone 17 is controlled to control the raw water recovery rate.

[0049] like Figure 10 , Figure 14 and Figure 15As shown, in this embodiment, the raw water tank 1 of the water purifier is covered with a filter element 160 with filter holes 161 at the raw water outlet 151. The raw water outlet 151 is connected to the interior of the raw water zone 16 through the filter holes 161. The filter element 160 can filter out small particulate impurities such as rust and sand in the raw water, improving the pumping effect and service life of the booster pump. To achieve this structure, an annular protrusion 190 can be provided on the bottom plate 15 of the raw water tank. The raw water outlet 151 is located inside the protrusion 190. The filter element 160 is cup-shaped, with cylindrical side walls 163 and bottom walls 162. Filter holes 161 are opened on the bottom wall 162. The filter element 160 is engaged with the protrusion 190 through the opening, and the raw water can only communicate with the interior of the raw water zone 16 through the filter holes 161. To ensure connection stability and accuracy, a positioning post 164 can be provided on the inner side of the side wall 163 of the filter element 160, and a positioning groove 1901 is provided on the corresponding boss 190. The positioning post 164 can be inserted into the positioning groove 1901. Alternatively, a positioning groove can be provided on the filter element 160, and a positioning post can be provided on the boss 190.

[0050] To complement the function of the return flow channel, a liquid level detection component 180 is installed in the raw water zone 16 of the raw water tank 1 in this embodiment of the water purifier to detect the raw water level. The liquid level detection component 180 can take various forms, such as a float structure or a sensor structure; many existing technologies exist and will not be elaborated upon here. Simultaneously, the lowest water level detection height of the liquid level detection component 180 is lower than the return flow height of the return flow channel. Through liquid level detection, the liquid level in the raw water zone 16 is controlled, especially the lowest raw water level, to prevent excessively high recovery rates that would render the return flow channel ineffective. Furthermore, the water level detection during water purifier use serves as a reminder to add water promptly.

[0051] In addition, this embodiment also provides a water purifier that uses the above-mentioned raw water tank 1, thereby improving the raw water recovery rate while minimizing the impact on raw water quality caused by the recycling of concentrated water. The water purifier includes a raw water tank 1, a filter device, and a storage tank base 3. The raw water tank 1 is the same as described above. The storage tank base 3 supports the raw water tank 1 and has a raw water outlet 3112 that cooperates with the raw water outlet 151 and a concentrated water outlet 3113 that cooperates with the concentrated water inlet 152. The filter device filters and purifies the raw water and has a raw water inlet connected to the raw water outlet 3112 and a concentrated water outlet connected to the concentrated water outlet 3113. The water tank base 3 is not an integrated design with the water purifier frame, but adopts a detachable split design. The raw water tank 1 can be detached and installed into the water purifier through the water tank base 3, forming a modular installation. The corresponding raw water tank 1 can be matched according to the needs of different product models, and it is also convenient for disassembly and cleaning operations such as filling the water tank with raw water or emptying concentrated water.

[0052] like Figure 16As shown, as a further improvement to the water purifier, the water storage tank base 3 includes a water storage tank base 31, a raw water inlet 3112, and a concentrated water inlet 3113 disposed on the water storage tank base 31. Combined with... Figure 12 and Figure 13 As shown, the bottom of the raw water tank 1 has a placement groove. A positioning plate 191 with a downward-sloping positioning ramp 192 is provided on the inner sidewall of the placement groove. The perimeter of the water storage tank base 31 has supporting ramps that cooperate with the positioning ramps 192 of the positioning plate 191. The positioning plate 191 at the bottom of the raw water tank 1, in cooperation with the supporting ramps on the water storage tank base 31, not only guides the placement of the raw water tank 1 but also provides excellent positioning support after placement, ensuring accurate alignment of the corresponding water inlets. Furthermore, the four sides of the raw water tank 1 extend downwards towards the bottom plate 15 to form a support plate 19. Positioning plates 191 are provided on the inner side of the support plate 19, and multiple plates can be spaced apart around the support plate 19 to facilitate stable support. Additionally, a guide ramp 193 with a larger slope can be provided below the positioning ramp 192 on the positioning plate 191, facilitating the placement of the raw water tank 1 onto the water storage tank base 3.

[0053] Preferably, such as Figure 16 As shown, an integrally formed side stand 32 is provided on the front side of the water tank base 31, and a hanging post 3211 with a hanging plug 3212 is provided on the side of the side stand 32 near the water tank base 31. Figure 8 , Figure 9 and Figure 11 As shown, the raw water tank 1 has a hanging slot 111 with a slot 113 on its raw water front panel 11. The hanging post 3211 cooperates with the hanging slot 111, and the hanging plug 3212 can be inserted into the slot 113. The water tank base 31 and the side stand 32 form an L-shaped installation space. With the cooperation of the hanging slots 111, the raw water tank 1 will not move or tip over on the water tank base 31, and the installation is stable and reliable. In addition, the main body of the hanging slot 111 has a positioning guide groove 112, which is formed by the inward indentation of the raw water front panel 11 of the raw water tank 1. The hanging slot 111 is located on the upper side of the positioning guide groove 112. The positioning guide groove 112 can cooperate with the hanging post 3211 on the side stand 32, and has a guiding and positioning function.

[0054] Example 3

[0055] Combination Figure 8 , Figure 10 , Figures 17-19As shown, in practice, when the raw water tank 1 needs to be replenished, the raw water zone 16 often has little water while the concentrated water zone 17 has plenty of water, making it prone to tipping over during handling. This embodiment further optimizes this problem by providing an anti-tipping raw water tank for a drinking water purification device. A handle 20 is connected to the raw water tank 1 for lifting the tank, and its two ends are pivotally connected to the tank body on opposite sides of the raw water tank 1. To achieve the anti-tipping function, as... Figure 10 As shown, the two pivot points connecting the handle 20 to the original water tank 1 are located on both sides of the partition plate 18. The intersection point D of the line connecting the two pivot points and the partition plate 18 in space is located in the middle area of ​​the partition plate 18. The included angle θ formed by the intersection satisfies: 45°<θ≤90°. The overflow height of the partition plate 18 is required to be no less than 1 / 3 of the maximum water storage height of the original water tank 1. The included angle θ can be any angle from 45° to 90°, such as 46°, 50°, 60°, 70°, 80°, and 90°. From the perspective of stability, the larger the angle, the more stable it is. At the same time, the intersection point D can be located in the middle or near the middle area of ​​the partition plate 18. The overflow height of the partition plate 18 has certain requirements. If the height is too low, it will not tip over even with slight imbalance. It will only tip over after reaching a certain height. Taking into account the water purifier's recovery rate and the function of the handle 20, the overflow height of the partition plate 18 is required to be no less than 1 / 3 of the maximum water storage height of the original water tank 1. For example, it can be 1 / 2, 2 / 3, or even the same as the maximum water storage height of the original water tank 1.

[0056] In this embodiment, the anti-tipping raw water tank 1 of the water purifier is designed with a handle 20 and a partition plate 18 staggered within the raw water zone 16 and the concentrated water zone 17. The staggered position of the handle 20 is controlled to ensure that it is simultaneously positioned in the middle of both the raw water zone 16 and the concentrated water zone 17. When one side of the tank has more water than the other, the weight balance when the raw water tank 1 is lifted is effectively maintained, preventing the tank from tipping over due to uneven weight distribution, which could cause raw water or concentrated water to splash out or even tip over. The raw water tank 1 has a cylindrical structure, and its cross-section can be circular, square, rectangular, or other irregular shapes. In this embodiment, the raw water tank 1 has a rectangular cylindrical structure, consisting of a front raw water tank plate 11, a rear raw water tank plate 12, a left raw water tank plate 13, a right raw water tank plate 14, and a bottom raw water tank plate 15. This structure is easy to manufacture and handle, and it is placed neatly on the water tank base 3. The partition plate 18 extends along the front-to-back direction to the middle of the front and rear sides of the raw water tank 1. The two ends of the handle 20 are pivotally connected to the middle of the left and right sides of the raw water tank 1. The middle position can be the center or near the center. The partition plate 18 can be flat or non-flat, such as curved, but a flat structure is preferred. With this structure, the partition plate 18 can more easily divide the raw water tank 1, the handle 20 is easier to install in a balanced position, and lifting and placing the raw water tank 1 is more convenient. Furthermore, the line connecting the two pivot points is perpendicular to the surface of the partition plate 18, which achieves better balance.

[0057] Considering the ease of handling and aesthetics of the original water tank 1, this embodiment further improves the handle 20. For example... Figure 8 , Figure 10 , Figure 17 and Figure 18As shown, the handle 20 is pivotally connected to the inside of the raw water tank 1, and has an overall U-shaped structure. It consists of connecting arms on the left and right sides parallel to the left and right side plates of the raw water tank 1, and a handle arm in the middle parallel to the front and rear side plates of the raw water tank 1. A lever part 23 is provided in the middle of the handle arm. An opening groove 121 is provided on the upper edge of the rear side of the raw water tank 1. When the handle 20 is rotated backward, the lever part 23 on the handle 20 can be engaged into the opening groove 121 on the raw water tank 1 and thus be limited. Of course, an opening groove 121 can also be provided on the upper edge of the front side of the raw water tank 1. In this case, when the handle 20 is rotated forward, the lever part 23 on the handle 20 can be engaged into the opening groove 121 on the raw water tank 1 and thus be limited. The handle 20 is stored inside the raw water tank 1, does not protrude, is more aesthetically pleasing, and facilitates the sealing of the raw water tank 1 through the cover plate. Meanwhile, to prevent the handle 20 from rotating and falling into the raw water tank 1 and touching the water, the opening groove 121 on the upper edge of the tank body can be engaged with the actuating part 23 of the handle 20 for effective restraint. This also facilitates lifting the raw water tank 1 by actuating the handle 20 from the outside of the tank, preventing unhygienic handling of the handle 20 from inside the tank. As a preferred embodiment, the actuating part 23 on the handle 20, after being engaged with the opening groove 121 on the raw water tank 1, is flush with or slightly protrudes from the outer surface of the tank, facilitating the actuation of the handle 20.

[0058] Considering the reliability of the connection between the handle 20 and the original water tank 1 and the rotation limit, such as Figure 10 , Figure 17 , Figure 18 , Figure 19As shown, in this embodiment, a pivot seat 30 is provided on the inner side of the left raw water tank plate 13 and the right raw water tank plate 14 of the raw water tank 1, near the upper middle position. It mainly consists of a support wall 31a spaced a certain distance from the left and right side plates of the raw water tank 1, two side connecting walls 32a spaced relatively perpendicular to the left and right side plates of the raw water tank 1, and a bottom connecting wall 33 located at the bottom of the support wall 31a and the two side connecting walls 32a. One end of the two side connecting walls 32a is connected to the end of the support wall 31a, and the other end is connected to the side plate of the raw water tank 1. Thus, the support wall 31a, the two side connecting walls 32a, and the side plate of the raw water tank 1 form a receiving space. The bottom connecting wall 33 closes the bottom of this receiving space, forming a cylindrical receiving space with an open top. A pivot hole 34 is provided on the support wall 31a of the pivot seat 30. The ends of the two connecting arms of the handle 20 each have a pivot shaft 21, which can be inserted into the pivot hole 34 to form a pivot connection structure. Furthermore, a rotating limiting member 22 protruding outward is provided on the rotating peripheral wall of the pivot shaft 21. Two upwardly protruding stop portions 35 that cooperate with the rotating limiting member 22 are provided at intervals along the front-back direction on the bottom connecting wall 33 inside the pivot seat 30. When the handle 20 is rotated to a certain angle in the front-back direction, the rotating limiting member 22 can abut against the stop portion 35 to limit its movement. In order to facilitate the insertion of the pivot shaft 21 into the pivot hole 34 on the pivot seat 30, a through groove is provided on the peripheral wall of the pivot hole 34 on the support wall 31a to allow the stop portion 35 to pass through. This through groove can not only allow the pivot shaft 21 to be inserted into the pivot hole 34, but also ensure the stability of the pivot rotation and prevent the pivot shaft 21 from dislodging from the pivot hole 34.

[0059] like Figure 11 and Figure 12 As shown, the bottom structure of the raw water tank 1 is further improved. Support plates 19 extend downwards from at least part of the bottom perimeter of the raw water tank 1. The support plates 19 and the bottom of the raw water tank 1 form a groove that allows the raw water tank 1 to be securely fastened onto the water storage tank base 31, thereby improving the stability of the raw water tank 1 when installed on the water storage tank base 31. Correspondingly, as... Figure 16 As shown, the water tank base 31 has supporting ramps on at least part of its perimeter, and here all four sides have them. A positioning plate 191 with a downward-sloping positioning ramp 192 is provided on the inner wall of the support plate 19. When the raw water tank 1 is placed on the water tank base 31 of the water tank seat 3, the positioning ramp 192 of the positioning plate 191 engages with the supporting ramp of the water tank base 31. Through the engagement of the support plate 19 on the raw water tank 1 with the ramp of the water tank base 31, the raw water tank 1 is guided when placed into the water tank base 31, making it easier to place and more accurately positioned. A guide ramp 193 with a larger slope can be provided below the positioning ramp 192 on the positioning plate 191 to further guide the placement of the raw water tank 1 onto the water tank seat 3, making it easier to place.

[0060] In addition, this embodiment also provides a water purifier, including a body and a raw water tank 1. The raw water tank 1 adopts the anti-tipping raw water tank 1 of the above-mentioned water purifier. The water storage tank base 3 is detachably installed on the body. With this water purifier structure, when the raw water tank 1 is lifted to add raw water or pour out concentrated water, it is more balanced and less likely to tilt, causing raw water or concentrated water to splash out or even tip over. At the same time, the detachable water storage tank base 3 on the body and the raw water tank 1 are modularly matched and can be replaced according to different needs, making it highly adaptable.

[0061] Example 4

[0062] This embodiment further provides a water purification tank for a water purifier. The water purification tank is movably installed on the water purifier and can be removed from it. This effectively improves the stability of the water purification tank during installation within the water purifier and prevents bacterial growth inside the tank for a longer period. This embodiment uses a household water purifier as an example to explain in detail its structure for achieving stable support and light-proof antibacterial functions.

[0063] like Figures 20 to 32 As shown, this embodiment provides a double-layered, light-proof, and antibacterial water tank for a water purifier, including a water tank 2, an outer shell 2a, and a water storage tank base 3. The water tank 2 stores purified water from the water purifier's filtration system. It is a tank structure with an internal water chamber for storing purified water. The bottom has an inlet hole 1051 connecting to the water chamber. The purified water from the water purifier's filtration system enters the water tank 2 through the inlet hole 1051, and water from the water tank 2 can also be sent to other functional units such as an ice tank for use through the inlet hole 1051. The water storage tank base 3 supports the water tank 2, which is placed on the base in a removable manner. The base 3 has a seat hole 304, configured to mate with the inlet hole 1051 when the water tank 2 is placed on the base 3, allowing purified water to enter and exit the water tank 2 through the seat hole 304 and the inlet hole 1051. In this embodiment, the water inlet 1051 at the bottom of the water tank 2 has downwardly protruding rings around it, which are inserted into the seat hole 304. During use, one-way check valves can be installed in both the water inlet 1051 of the water tank 2 and the seat hole 304 of the water tank seat 3. When the water tank 2 is placed on the water tank seat 3, both one-way check valves open, allowing for connection. When the water tank 2 is removed from the water tank seat 3, both one-way check valves close, achieving a seal, thus satisfying the requirements for placing and removing the water tank 2.

[0064] In this embodiment, a specially designed outer shell 2a is mounted on the water tank base 3. It is configured such that the purified water tank 2 can be inserted into the outer shell 2a from above, so that when the purified water tank 2 is placed on the water tank base 3, its outer perimeter is completely enclosed within the outer shell 2a. At least a portion of the outer shell 2a serves as the exposed body part of the water purifier, and at least a portion of the outer shell 2a is opaque, with the opaque portion including at least the exposed body part of the water purifier. At least a portion of the purified water tank 2 is transparent, allowing the water level to be observed through this transparent portion. For example, the outer shell 2a can be completely opaque, or only the exposed portion of the outer shell 2a can be opaque, allowing the purified water tank 2 to be either completely transparent or only partially transparent. In this embodiment, the outer shell 2a adopts a completely opaque structure, while the purified water tank 2 adopts a fully transparent structure.

[0065] The double-layered, light-proof, and antibacterial water tank of this water purifier supports the water tank 2 via a water storage tank base 3 on the main body. The water tank 2 is installed inside the outer shell 2a, which provides stable support and sealing for the water tank 2. The water tank 2 is not easily detached from the main body during transportation or accidental impact. At the same time, the outer shell 2a can also serve as the outer shell of the main body and is opaque, so light will not shine into the water tank 2, which can effectively reduce the growth of bacteria inside the water tank 2 and keep the water fresh for a long time. In addition, the water tank 2 has a transparent part, which allows direct observation of the water level and facilitates user operation.

[0066] To achieve the effect of an opaque outer shell 2a and a transparent water tank 2, this embodiment makes the outer shell 2a from opaque plastic and the water tank 2 from transparent plastic. Using plastic is cost-effective, allows for rapid injection molding, and offers high shape flexibility. Alternatively, the outer shell 2a can be made of opaque plastic itself, or an opaque film can be attached to its surface.

[0067] As one implementation of the outer casing 2a, the outer casing 2a can be a cylindrical structure with side walls on all four sides and openings at the top and bottom, with the bottom opening mounted on the water tank base 3. As another preferred embodiment, considering the mounting structure of the outer casing 2a on the water tank base 3, in this embodiment, the water tank base 3 includes an integrated base plate 301 and a vertical plate 302. The outer casing 2a, together with the base plate 301 and vertical plate 302 of the water tank base 3, form a space that can accommodate the purified water tank 2. The base plate 301 and vertical plate 302 form an L-shaped mounting space, which, in conjunction with the outer casing 2a, forms a space with an upper opening to accommodate the purified water tank 2, thus meeting the installation space requirements of the purified water tank 2 and simplifying the structure as much as possible for easy overall assembly.

[0068] like Figure 22 , Figure 24 , Figure 25As shown, in this embodiment, the outer shell 2a is mainly composed of a left shell plate 201, a right shell plate 202, and a rear shell plate 203, with open sides on the top, bottom, and front. When the bottom of the outer shell 2a is installed on the water tank base 3, its bottom opening is closed by the base plate 301, and its front opening is closed by the upright plate 302, thus forming a space for the purified water tank 2 to be inserted from the top opening, providing stable support and light protection. Correspondingly, the purified water tank 2 is mainly a box structure formed by the purified water left tank plate 101, purified water right tank plate 102, purified water front tank plate 103, purified water rear tank plate 104, and purified water tank bottom plate 105, with an openable tank cover 106 at the top opening for pouring water.

[0069] To facilitate the removal and placement of the water purification tank 2 from the outer casing 2a, a handle 107 is pivotally connected near the top of the water purification tank 2. A storage groove 206 is provided at the upper end of the outer casing 2a to engage with the handle 107. The handle 107 is configured such that when the water purification tank 2 is placed on the water storage tank base 3 and the handle 107 is rotated to retract, the handle 107 resides within the storage groove 206 of the outer casing 2a, neither protruding beyond the side wall of the outer casing 2a nor flush with the side wall. This structural design of the handle 107 facilitates lifting the water purification tank 2 while maintaining an aesthetically pleasing and compact appearance. Here, the handle 107 is designed in a U-shape, pivotally connected to the outer sides of the left and right panels of the water purification tank 2 for easy lifting.

[0070] like Figure 23-31 As shown, considering the stability of the water tank 2 placed on the water tank base 3, in this embodiment, the bottom of the water tank 2 has downwardly extending support portions 108 around its perimeter. The base plate 301 of the water tank base 3 has an upwardly protruding boss in the middle, which includes an inner horizontal section 3011 and an inner vertical section 3012. The water tank 2 is supported on the base plate 301 of the water tank base 3 by the support portions 108, which are located outside the boss. The bottom of the water tank 2 is spaced apart from the inner horizontal section 3011 of the boss. With this structure, the water tank 2 is reliably supported on the water tank base 3, and the boss restricts the planar movement of the water tank 2. At the same time, the bottom of the water tank 2 is not in contact with the inner horizontal section 3011 of the boss, considering the difficulty of achieving a completely flat support and also facilitating the installation of corresponding matching water valves on the water tank 2 and the water tank base 3. Preferably, the inner side of the support 108 has a limiting part 109 extending towards the boss. The limiting part 109 and the inner vertical section 3012 of the boss of the seat plate 301 have limiting inclined surfaces that can cooperate with each other to play a guiding role, so as to facilitate the water tank 2 to be installed into the outer shell 2a and accurately supported and installed on the water tank seat 3.

[0071] To ensure the stable and reliable installation of the outer casing 2a on the water tank base 3, in this embodiment, the base plate 301 of the water tank base 3 is provided with multiple insertion portions 303 with slots A3031; the lower part of the outer casing 2a is provided with a downwardly extending insertion plate 205. The insertion plate 205 can be inserted into the slots A3031 of the insertion portions 303, thereby achieving stable positioning and installation. Preferably, the base plate 301 of the water tank base 3 is provided with an outer horizontal section 3015 on one or both sides, and the lower part of the outer casing 2a is provided with a step 204. The step 204 supports and abuts against the outer horizontal section 3015, achieving secondary positioning of the outer casing 2a and preventing it from moving. In this embodiment, the water tank base 3 has an outer horizontal section 3015 on the right side of the base plate 301. The insert plate 205 of the outer shell 2a is horizontally spaced from the right shell plate 202. The insert plate 205 is offset inward, and the two are connected by a connecting section, which serves as a step 204. A protruding edge 3016 is formed on the left side edge (outer edge) of the base plate 301 of the water tank base 3. The insert plate 205 of the outer shell 2a is located inside the edge 3016, facilitating the installation of the outer side panel of the water purifier. The inner vertical section 3012 and the outer horizontal section 3015 of the water tank base 3 are connected sequentially by a bottom horizontal section 3013 and an outer vertical section 3014. The height of the outer horizontal section 3015 is higher than that of the inner horizontal section 3011, thus forming the aforementioned interlocking structure.

[0072] To enable the water purifier tank 2 to be quickly and accurately placed into the outer casing 2a, in this embodiment, guide portions 207 protruding from the inner sidewalls of the outer casing 2a are provided on the left and right inner sidewalls. The guide portions 207 extend downwards and have inclined guide surfaces. The left and right opposite guide surfaces form the guide width for placing the water purifier tank 2 into the outer casing 2a, and the guide width gradually decreases from top to bottom. The left and right opposite outer sidewalls of the water purifier tank 2 are inclined surfaces that cooperate with the guide surfaces of the guide portions 207 on the left and right inner sidewalls of the outer casing 2a, and their widths gradually decrease from top to bottom. That is, the opening of the outer casing 2a is wider at the top and narrower at the bottom, and the water purifier tank 2 is similarly shaped. Therefore, the water purifier tank 2 can be easily inserted into the opening of the outer casing 2a, and under the guidance of the guide portions 207 of the outer casing 2a, the water purifier tank 2 is quickly and accurately placed in place.

[0073] As a preferred option, the width of the left and right outer walls of the water tank 2 is designed to fit into the storage compartment inside the refrigerator door. For example, the maximum width of the water tank 2 can be set to 10cm, 9cm, 8cm, 7cm, 5cm, 4cm, etc. Users can easily remove the water tank 2 from the water purifier, place it in the storage compartment on the side of the refrigerator door to cool, and then put it back into the water purifier for quick access to cold water.

[0074] In addition, such as Figure 33As shown, this embodiment also provides a water purifier, including a frame and the aforementioned double-layered, light-proof, and antibacterial water tank. The water tank base 3 can be installed on the frame via a detachable structure such as clips or screws. The left and right sides of the outer casing 2a serve as the outer walls of the water purifier, exposed to the outside. This water tank structure of the water purifier is aesthetically pleasing, provides good stability for the water tank, and prevents direct sunlight from illuminating the water tank 2, ensuring that the water quality is not easily preserved for long periods.

[0075] Example 5

[0076] This embodiment also provides a water storage device for a water purifier, which adopts a modular structure design and can be installed as a whole onto the water purifier body. It is also a modular assembly method, suitable for different specifications and models, and has strong versatility. For example... Figure 16 , Figures 34-38 As shown, the water purifier's water storage device mainly consists of three parts: raw water tank 1, purified water tank 2, and water storage tank base 3. Both raw water tank 1 and purified water tank 2 are supported on the water storage tank base 3 in a removable manner.

[0077] In this embodiment, the water tank base 3 mainly consists of a water tank base 31 and a side stand 32. Both the water tank base 31 and the side stand 32 can be made of plastic, such as ABS plastic, obtained through injection molding. Water tank base 3 made of this material has excellent overall performance, low cost, high production efficiency, and light weight. The water tank base 31 can be plate-shaped, generally not flat, but rather a plate with concave and convex shapes and a specific installation position, placed flat to support the raw water tank 1 and the purified water tank 2. The side stand 32 can also be plate-shaped, placed vertically on the front side of the water tank base 31. The raw water tank 1 and the purified water tank 2 are placed side-by-side on the water tank base 31 of the water tank base 3 in a left-right direction, with their front sides close to the side stand 32 of the water tank base 3. The sides of adjacent tanks are close together; close means that the side panels can be fitted together, or there can be a small distance between them. The side stand 32 and the original water tank 1 can be detachably connected by a hook fastener. When the hook fastener is configured to be placed on the water tank base 31 of the water tank stand 3, it can restrict the positional movement of the original water tank 1 in any direction other than the upward lifting direction.

[0078] The water storage device of the water purifier in this embodiment adopts a modular structure design. The raw water tank 1 and the purified water tank 2 are installed side by side on the water storage tank base 3 in a detachable manner. The water storage tank base 3 itself is also an integrated detachable structure. The three together form a water storage module, which can be installed as a whole on the water purifier. This not only makes full use of the machine space, but also allows the water storage module to be adapted to different models, making it relatively versatile. In addition, the water storage tank base 3 isolates the raw water tank 1 and the purified water tank 2 from other parts of the water purifier, forming an effective water area isolation and reducing the impact of water on other components.

[0079] like Figures 37 to 38 As shown, a structural form of raw water tank 1, purified water tank 2, and water storage tank base 3 is provided for one embodiment. Both raw water tank 1 and purified water tank 2 can be generally rectangular barrel-shaped boxes. Considering the optimization of the water capacity carried by raw water tank 1 and purified water tank 2, the width of raw water tank 1 in the left-right direction is greater than the width of purified water tank 2, and the length of purified water tank 2 in the front-back direction is greater than its width in the left-right direction. Combined with... Figure 16 and Figure 35 As shown, considering the different volumes occupied by the raw water tank 1 and the purified water tank 2, and to fully utilize the space of the water purifier, the water tank base 31 is divided into a raw water base 311 and a purified water base 312 along the left and right directions. Correspondingly, the side stands 32 are divided into a raw water stand 321 and a purified water stand 322. The raw water base 311 has a raw water tank platform 3111 for supporting the installation of the raw water tank 1, and the purified water base 312 has a purified water tank platform 3121 for supporting the installation of the purified water tank 2. The height of the raw water tank platform 3111 is higher than that of the purified water tank platform 3121. Simultaneously, the rear side of the raw water tank 1 can be flush with the rear side of the purified water tank 2, occupying only a rectangular area on the water purifier. The arrangement is compact, with high space utilization and an overall aesthetically pleasing appearance.

[0080] The water purifier base 312 includes a protective plate 3221, a side connecting plate 3222, and a side wing plate 3223. The side connecting plate 3222 extends in the left-right direction, and the protective plate 3221 extends in the front-back direction, with its front side extending to the left side of the original water tank 321 and its rear side connecting to one side of the protective plate 3221. The side wing plate 3223 extends in the front-back direction, with its rear side connecting to the other side of the protective plate 3221. The side connecting plate 3222 can serve as a partition between the left and right sides of the original water tank 1 and the purified water tank 2, making the side of the original water tank 1 more stable on the side connecting plate 3222. The protective plate 3221 can be adapted to fit the shape of the front side of the purified water tank 2, for example, the middle is recessed to the front to form a spout shape. The side wing plate 3223 can play a reinforcing role and can also serve as a connection base for other components, such as the side plate of a water purifier. A connector 3114 is provided at the bottom of the water tank base 31 of the water tank seat 3 for detachably installing the water tank seat 3 onto the water purifier frame. One or more connectors can be provided, for example, on the left and right sides and the rear side. The connector 3114 can be a downwardly protruding plate, for example, with round holes and slots. It can engage with stud holes on the water purifier frame via screws through the round holes, or engage with latching protrusions on the frame through the slots. Other connection methods are also possible. One or more connecting parts 3213 are provided on the side stand 32 of the water tank seat 3, for example, along the right edge of the original water stand 321 in the vertical direction, to connect with other components of the water purifier body. These can be connected using the same method as the connector 3114, or using a slot structure, latching protrusion structure, stud structure, etc.

[0081] Combination Figure 16 and Figure 35As shown, in a preferred connection method between the raw water tank 1 and the raw water support 321, the raw water support 321 has a hanging post 3211 with a hanging plug 3212 on its side near the water storage tank base 31. The raw water tank 1 has a hanging slot 111 with a slot 113. The hanging post 3211 and the hanging slot 111 form a fastener. The hanging post 3211 and the hanging slot 111 cooperate, and the hanging plug 3212 can be inserted into the slot 113. Here, the main body of the hanging slot 111 on the front side of the raw water tank 1 is a positioning guide groove 112 that is recessed to the rear. The positioning guide groove 112 cooperates with the hanging post 3211 to achieve positioning guidance. The slot 113 is located at the upper end of the positioning guide groove 112. The raw water tank 1 and the raw water support 321 form a fastener through the cooperation of the hanging post 3211 and the hanging slot 111. The raw water tank 1 will not move or tip over on the water storage tank base 31, and the installation is stable and reliable.

[0082] As an optimized fit between the water tank and the water storage tank base 3, the bottom of the raw water tank 1 has a slot that can be inserted into the surrounding area of ​​the raw water tank base 3111. The surrounding area of ​​the raw water tank base 3111 has guiding slopes that cooperate with the slots and slopes at the bottom of the raw water tank 1 for positioning. The bottom of the purified water tank 2 has a slot that can be inserted into the surrounding area of ​​the purified water tank base 3121. The surrounding area of ​​the purified water tank base 3121 also has guiding slopes that cooperate with the slots and slopes at the bottom of the purified water tank 2 for positioning. Through the inclined insertion fit between the tank body and the base, a guiding effect is provided when the water tank is placed into the water storage tank base 31, making it easier to place and more accurately positioned.

[0083] In addition, such as Figure 38 As shown, this embodiment also provides a water purifier, including a frame and a raw water tank 1. The raw water tank 1 adopts the modular, split-type raw water tank 1 described above. The frame has an installation space for installing a water storage tank base 3. The raw water tank 1 is detachably installed in the installation space on the frame via a connector 3114 on the water storage tank base 3. The right and rear sides of the raw water tank 1, and the left and rear sides of the purified water tank 2 are exposed as the outer shell of the water purifier. In this water purifier, the raw water tank 1 can be installed as a whole, which not only facilitates the full utilization of the machine space, but also allows the water storage module to be adapted to different models, making it relatively versatile.

[0084] Example 6

[0085] This embodiment also provides a water purifier that optimizes the layout of the internal water and electrical components to maximize space utilization and improve operational safety and versatility. Figures 39 to 44The illustrated water purifier includes a frame 9 and a power adapter 95, a circuit board assembly 94, and a water circuit board assembly 96 installed within the frame 9. The power adapter 95 supplies power to the water purifier. The circuit board assembly 94 controls the water purifier's circuitry and is electrically connected to the power adapter 95. The water circuit board assembly 96 houses the filter cartridge and distributes water throughout the water purifier's circuit. The circuit board assembly 94 typically includes a water circuit board, control valves, a pump, and filter cartridges, which are combined according to different functional requirements. This is prior art and will not be described in detail here.

[0086] In this embodiment, the circuit board assembly 94, power adapter 95, and water circuit board assembly 96 are all centrally mounted on one side of the frame 9, such as the front left side of a water purifier, and are arranged vertically from top to bottom. Correspondingly, the frame 9 has a circuit board mounting position 92, an adapter compartment 91, and a water circuit board compartment 93 arranged sequentially from top to bottom on the front left side. The circuit board assembly 94, power adapter 95, and water circuit board assembly 96 are respectively mounted in their respective positions. Meanwhile, the circuit board mounting position 92 is configured to allow the circuit board assembly 94 to be detachably mounted on it. The adapter compartment 91 is configured to allow the power adapter 95 to be detachably mounted from top to bottom along its length. The water circuit board compartment 93 is configured to allow the water circuit board assembly 96 to be detachably mounted in a horizontal orientation. "Horizontal" means that the thickness direction of the water circuit board assembly 96 is along the vertical direction, while the front-back and left-right directions are horizontal.

[0087] In this embodiment, the water purifier has a high degree of centralized installation by centrally installing the circuit board assembly 94, power adapter 95 and water circuit board assembly 96 on one side of the water purifier frame 9. This results in a reasonable space occupation and facilitates the improvement of the universality of various models. At the same time, the circuit components and water circuit components are arranged vertically to achieve better water and electricity separation, and the equipment has relatively high operating safety.

[0088] To further enhance operational safety, the adapter compartment 91 and the water circuit board compartment 93 are separated by an isolation plate 97, providing spatial isolation and thorough separation of water and electricity. Both the adapter compartment 91 and the water circuit board compartment 93 are open towards the outside of the water purifier, allowing the power adapter 95 and the water circuit board assembly 96 to be installed in their respective compartments. Of course, the adapter compartment 91 and the water circuit board compartment 93 can also be open or closed in other directions, depending on specific functional needs, but the side facing the outside of the water purifier must be open. Furthermore, the open sides of the adapter compartment 91 and the water circuit board compartment 93 can be closed by installing a side panel of the water purifier. Removing and installing the side panel not only improves the overall aesthetics of the water purifier but also facilitates the inspection and maintenance of the power adapter 95 and the water circuit board assembly 96. As a further improvement, a drainage hole is provided at the bottom of the water circuit board compartment 93, which can be located on the bottom plate of the water purifier, allowing for timely detection of leaks in the water circuit board assembly 96.

[0089] To improve the installation reliability of the power adapter 95 in the adapter compartment 91, a support plate A911a with a supporting plane is provided inside the adapter compartment 91. The power adapter 95 is supported on the supporting plane of the support plate A911a inside the adapter compartment 91. This structure provides a large supporting surface for the power adapter 95, ensuring a secure and stable installation. In addition to supporting the power adapter 95 with the support plate A911a, connecting posts 912a are provided on both the upper and lower sides of the adapter compartment 91 near the support plate A911a. The power adapter 95 is then installed and fixed using the connecting posts 912a. For example, the connecting posts 912a can be studs, with screws used to fix the pressure ring to the studs. The pressure ring can then press the wires at both ends of the power adapter 95. Alternatively, other installation methods such as a snap-fit ​​structure can be used.

[0090] Further considering the preferred mounting method of the circuit board assembly 94, the circuit board mounting position 92 is a bracket extending from the frame 9. The circuit board assembly 94 is mounted on the bracket using fasteners such as screws and clips. There can be one or more brackets; the attached figure shows two brackets. In one embodiment, the circuit board assembly 94 includes a circuit board, a housing 941, and a cover 942. The housing 941 is fixed to the bracket, and the circuit board is placed inside the housing 941 and sealed by the cover 942. Preferably, the circuit board is a PCB circuit board, which is installed inside the housing 941 by potting adhesive, improving the circuit board's safety and shock resistance.

[0091] To facilitate the connection of the power adapter 95 to an external power source, a cable tray 931 extends from the water circuit compartment 93. The power cord with the plug of the power adapter 95 can be installed along the cable tray 931 and extends out of the water purifier. As one implementation of the cable tray 931, it is set on the bottom plate of the water purifier and formed by a pair of upright plates that extend upward from the bottom plate at a certain distance from each other.

[0092] Example 7

[0093] through Figures 45-54As shown, this embodiment also provides a water distribution system for a water purifier, including: a filter water circuit plate 900, which is used to install a filter module 903. The filter water circuit plate 900 has a water flow channel, and has an interface for connecting raw water and an outlet for filtering purified water. Raw water enters the filter module 903 through the interface for filtration and then flows out through the outlet. It also includes a water distribution transfer valve assembly 800, which is connected to the filter water circuit plate 900. Specifically, the valve assembly body of the water distribution transfer valve assembly 800 has a main flow channel 819 and at least one secondary flow channel. The main flow channel 819 is provided with... There are two ports: a purified water inlet 803 and a purified water outlet 804. The purified water inlet 803 is connected to the filter element water circuit board 900 through a pipe and is used to receive the purified water filtered by the filter element module 903 and connect the purified water to the main flow channel 819. The purified water outlet 804 is used to connect to the purified water tank of the drinking water purification equipment and connect the purified water in the main flow channel 819 to the purified water tank of the drinking water purification equipment. The main flow channel 819 and the secondary flow channel are connected by a water pump. The water pump inlet is connected to the main flow channel 819 and the water pump outlet is connected to the secondary flow channel. The water pump is used to pump the purified water in the main flow channel 819 to the secondary flow channel. The secondary flow channel is equipped with an outlet for connecting the purified water to the corresponding functional module of the drinking water purification equipment.

[0094] In this embodiment, the water distribution transfer valve assembly 800 does not have a mounting position for the filter module 903, but instead has an independent filter water circuit board 900 for mounting the filter module 903. The filter water circuit board 900 has a filter clean water inlet 911 and a filter inlet 912, which are respectively used to connect to the corresponding interfaces of the filter module 903. That is, the filter inlet 912 is used to connect to the inlet of the filter module 903, and the filter clean water inlet 911 is used to connect to the clean water outlet of the filter module 903. Combined with... Figure 48 and Figure 49 As shown, specifically:

[0095] The filter element water circuit board 900 is provided with a raw water flow channel 919 that connects to the filter element inlet 912, so that raw water can enter the filter element module 903. More precisely, the filter element water circuit board 900 is also provided with a motor outlet 907, which is used to connect to the power motor of the filter element module 903, so that the raw water is pumped out by the power motor and enters the raw water flow channel 919 through the motor outlet 907, and finally enters the filter element module 903. The raw water flow channel 919 is also provided with a water quality detector 906, which is used to detect the water quality before filtration.

[0096] The filter element water circuit board 900 is provided with a clean water flow channel 921 that connects to the filter element clean water inlet 911, and a one-way valve 905 is connected to the clean water flow channel 921. The one-way valve 905 is used to discharge clean water through the clean water outlet 915. Specifically, the inlet of the one-way valve 905 is connected to the clean water flow channel 921, and the outlet of the one-way valve 905 is connected to the clean water outlet flow channel. The clean water outlet 915 is located in the clean water outlet flow channel, and the clean water outlet flow channel and the clean water flow channel 921 are connected through the one-way valve 905.

[0097] Corresponding to different choices of filter module 903 in practice, when filter module 903 uses RO filter, filter water circuit board 900 is also provided with filter wastewater port 910, which is used to connect with the wastewater interface of filter module 903; filter water circuit board 900 is provided with wastewater channel 920 connected to filter wastewater port 910, and wastewater valve 904 is connected to wastewater channel 920, which is used to discharge wastewater through wastewater outlet 916; similarly, the inlet of wastewater valve 904 is connected to wastewater channel 920, and the outlet of wastewater valve 904 is connected to wastewater outlet channel, and wastewater outlet 916 is located in wastewater outlet channel. Wastewater outlet channel and wastewater channel 920 are connected through wastewater valve 904, and wastewater is discharged through wastewater outlet 916.

[0098] This embodiment uses a filter element water circuit board 900 for direct installation of the filter element module 903, and only requires the necessary installation components. This allows the filter element water circuit board 900, after installing the filter element module 903, to form the most basic and functionally independent integrated filtration module of the drinking water purification equipment, exhibiting strong versatility and adaptability. The water distribution transfer valve assembly 800 serves as a separate downstream purified water distribution valve assembly. It receives purified water filtered by the filter element module 903 through the purified water inlet 803, and then distributes the purified water to the purified water tank and corresponding functional modules using the purified water outlet 804 and the distribution of secondary flow channels, achieving multi-directional transfer and distribution of purified water. This design simplifies the structure of the filter element water circuit board 900 and the water distribution transfer valve assembly 800, reducing the number of pipes and resulting in a smaller overall size of the water purifier. Furthermore, different water distribution transfer valve assemblies 800 can be directly replaced depending on the function of the water purifier. For example, when the water purifier only needs to supply hot or cold water, the water distribution transfer valve assembly 800 can have only a single secondary flow channel, using a single water pump to deliver purified water to the corresponding heating or cooling module. When both hot and cold water are required, the water distribution transfer valve assembly 800 can have dual secondary flow channels, using different water pumps to deliver purified water to the heating and cooling modules respectively. By replacing the valve assembly body according to the functional changes without altering the filter element water circuit board 900, the filter element water circuit board 900 can be universally applied for different functions, effectively reducing production costs and facilitating component disassembly and assembly.

[0099] In this embodiment, to achieve comprehensive functionality of the water purification equipment, the valve assembly body is provided with two secondary flow channels, namely the primary flow channel 820 and the secondary flow channel 821, combined with... Figures 51-54 As shown, the first flow channel 820 and the main flow channel 819 are connected by a first water pump 805. The inlet 814 of the first water pump is connected to the main flow channel 819, and the outlet 813 of the first water pump is connected to the first flow channel 820. The first water pump 805 is used to pump clean water from the main flow channel 819 into the first flow channel 820. The first flow channel 820 is provided with a first outlet 809. Correspondingly, the second flow channel 821 and the main flow channel 819 are connected by a second water pump 806. The inlet 816 of the second water pump is connected to the main flow channel 819, and the outlet 815 of the second water pump is connected to the second flow channel 821. The second water pump 806 is used to pump clean water from the main flow channel 819 into the second flow channel 821. The second flow channel 821 is provided with a second outlet 812. Specifically, the drinking water purification device in this embodiment has drinking functions for room temperature water, hot water, and cold water. The room temperature water and hot water share a common water inlet, and a heating element is installed in the water inlet pipeline as a heating module, which is used to heat and prepare hot water when needed, and to discharge room temperature water when the heating element is not running. The drinking water purification device also has a cooling module for preparing cold water. The first outlet 809 is used to connect to the cooling module to provide purified water to the cooling module; the second outlet 812 is used to connect to the pipeline where the heating element is located to provide purified water to the heating module.

[0100] In this embodiment, the valve assembly body has a plate-like structure, specifically composed of a water distribution plate 1 801 and a water distribution plate 2 802 joined together. Internally, it forms a main flow channel 819 and at least one secondary flow channel. The purified water inlet 803 and the purified water outlet 804 are located at the same end of the valve assembly body, as detailed below. Figure 51 As shown, the valve assembly body has a rectangular plate-like structure. The purified water inlet 803 and purified water outlet 804 are located at the same end along the length direction and are arranged side by side along the width direction of the valve assembly body at this end. This makes the valve assembly body more compact and space-saving, and facilitates pipe connections inside the drinking water purification equipment. Preferably, the purified water inlet 803 and purified water outlet 804 are located on the same water distribution plate, such as on water distribution plate 801. Preferably, to further enhance the layout advantages of each component, the second outlet 812 is also located on a water distribution plate. This water distribution plate has a mating groove for installing the second outlet 812, so that at least a portion of the second outlet 812 is embedded in the water distribution plate, such as... Figure 52 As shown, the second outlet 812 is distributed on the second water distribution plate 802. The second water distribution plate 802 is provided with a mating groove for installing the second outlet 812, so that at least a portion of the second outlet 812 is embedded in the second water distribution plate 802, and the second outlet 812 extends along the width direction of the valve assembly body.

[0101] In the industry, water purification equipment often uses RO reverse osmosis membrane filter cartridges as the core filtration material. When the water purification equipment is in a shutdown or standby state, there is both concentrated water and purified water in the RO reverse osmosis membrane filter cartridge. The total dissolved solids (TDS) concentration of the concentrated water is much higher than that of the purified water. This causes ions in the concentrated water to diffuse into the purified water, resulting in a higher TDS concentration in the first cup of water when the water purification equipment is turned on again. This problem has become a pain point for water purification equipment.

[0102] To address the issue of high TDS concentration in the first cup of water, this embodiment includes an additional fresh water rinsing component on the valve assembly body. Specifically, the valve assembly body also includes a fresh water inlet channel 822 and a fresh water outlet channel 823, connected by a third water pump 807. The inlet 818 of the third water pump is connected to the fresh water inlet channel 822, and the outlet 817 of the third water pump is connected to the fresh water outlet channel 823. The fresh water inlet channel 822 is equipped with a fresh water inlet 811. The live water inlet 811 is used to connect to and receive the purified water in the purified water tank of the drinking water purifier; the live water outlet 823 is provided with a live water outlet 810, which is used to connect the purified water to the filter module 903 of the drinking water purifier. Thus, the remaining purified water in the purified water tank can be sent to the filter module 903 through the third water pump 807. After the filter module 903 stops producing purified water, the surface of the filter element is rinsed and finally discharged to the raw water tank of the drinking water purifier through the filter waste water outlet, thereby effectively improving the problem of excessive TDS in the first cup of water and improving the water quality of the first cup of water.

[0103] As a different implementation method, the fresh water outlet 810 can also connect the purified water directly to the raw water tank of the water purifier. In this case, the residual purified water in the purified water tank can be directly discharged into the raw water tank to replace the purified water. When the purified water has been left for a long time and the user does not want to drink it directly, this method can be chosen to directly replace the purified water back into the raw water tank, which not only avoids wasting water but also keeps the purified water in the tank fresh. In practice, the fresh water outlet 810 can also be connected to the filter module 903 and the raw water tank through pipes, thereby achieving both the freshness function of the purified water tank and the rinsing effect of the filter.

[0104] To achieve a compact and rational layout, in this embodiment, multiple water pumps on the valve assembly body are all distributed on the same side of the valve assembly body, and as shown... Figure 52 As shown, in conjunction with the elongated plate structure of the valve assembly body, multiple water pumps are preferably arranged along the length of the valve assembly body, making the spatial layout more compact. More optimally, the multiple water pumps on the valve assembly body, along with the purified water inlet 803 and purified water outlet 804, are mounted on the same water distribution plate, such as on water distribution plate 801; this allows for the centralized installation of multiple components on the same water distribution plate. Figure 51As shown, the first water pump 805, the second water pump 806 and the third water pump 807 are all installed on one side of the water distribution plate 801 and are arranged along the length of the valve assembly body.

[0105] To enable timely detection of the water quality of the filtered purified water, a water quality detector 808 can be installed at the front end of the main channel 819 in this embodiment to detect the water quality of the purified water entering the main channel 819.

[0106] This embodiment also provides a water purification device that employs the multi-functional modular water distribution system described above. The filter module 903 is installed on the filter water circuit board 900, and the purified water outlet 915 on the filter water circuit board 900 is connected to the purified water inlet 803 on the water distribution transfer valve assembly 800 via a pipeline. The purified water outlet 804 on the water distribution transfer valve assembly 800 is connected to the purified water tank via a pipeline. Through the coordinated operation of the filter water circuit board 900 and the water distribution transfer valve assembly 800, multi-directional purified water distribution can be achieved. Furthermore, different water distribution transfer valve assemblies 800 can be replaced according to changes in the function of the water purification device without altering the filter water circuit board 900. This enables the universal application of the filter water circuit board 900 under different functions, thereby reducing production costs.

[0107] As a specific preferred installation method, combined with Figure 45 As shown, the filter module 903 in the water purifier is vertically fixed on the filter water circuit board 900, which is correspondingly horizontally positioned. The water distribution valve assembly 800 is vertically installed inside the water purifier and is connected to the filter water circuit board 900. Figure 45 The diagram shows the installation position inside the water purification equipment. The filter water circuit board 900 and the water distribution transfer valve assembly 800 are distributed on different planes and are vertically arranged, which makes it easier to arrange them reasonably according to the internal space layout of the equipment, achieve a more compact installation, and further facilitate the miniaturization of the whole machine. At the same time, the water distribution transfer valve assembly 800 is arranged vertically, with the pump bodies of each water pump extending horizontally. The inlets and outlets of each water pump on the valve assembly body are distributed vertically, and the water pump outlets are all located below the water pump inlets. This helps to fully combine the gravity factor of water flow to ensure stable water flow and stable operation of each pump body.

[0108] Example 8

[0109] Combination Figures 55-56As shown, this embodiment also provides a convenient gas cylinder installation component for a water purifier, including a mounting frame and an aeration module. The mounting frame is used to install and support the aeration module, which is used to inject gas into drinking water to make sparkling water. The aeration module includes a gas cylinder 601 and an aeration adapter 602. The mounting frame has a gas cylinder installation space, in which the gas cylinder 601 is installed. The aeration adapter 602 has an installation screw port for connecting to the gas cylinder 601. When the gas cylinder 601 is installed in the installation space, it can be detachably connected to the aeration adapter 602 using the installation screw port, thus connecting the gas path. Specifically, a threaded screw port is used, and the gas cylinder 601 has a corresponding installation thread at its opening. The aeration adapter 602 also has a switch for controlling the gas path opening and closing.

[0110] As a different design for the gas injection adapter 602, one implementation scheme is that the gas injection port of the gas injection adapter 602 is connected to the water faucet pipe of the water purifier. The water faucet pipe is the pipe connected to the water faucet for discharging purified water. Specifically, the gas injection port of the gas injection adapter 602 is connected to the cold water outlet pipe of the water purifier. That is, when needed, by controlling the gas circuit switch, the gas in the gas cylinder 601 can be directly injected into the cold water in the outlet pipe through the gas injection adapter 602, so as to directly prepare sparkling water for users to drink inside the water purifier. The external structural design of the water purifier can be further simplified and made more beautiful.

[0111] Another embodiment of the gas injection adapter 602 is as follows: combined with Figure 55 As shown, the gas injection adapter 602 is equipped with a gas injection adapter channel 603, which is also connected to the gas cylinder 601. The end of the gas injection adapter channel 603 is equipped with a water cup connector 604. The water cup connector 604 has an interface for detachably installing a sparkling water cup 605. This interface has a gas injection port for injecting gas into the sparkling water cup 605. Specifically, the interface on the water cup connector 604 can also be a threaded type. The sparkling water cup 605 has a corresponding installation thread at its opening. Installing the sparkling water cup 605 containing cold water onto the water cup connector 604 will start the gas injection process and produce sparkling water. This method makes the sparkling water injection and cold water filling operations independent, allowing users to separately fill with cold water and choose whether to prepare sparkling water.

[0112] It should be noted that in this embodiment, the bottom of the gas cylinder 601 installed on the gas injection adapter 602 has an elastic support component. The elastic support component has an elastic clearance distance and is configured such that when the gas cylinder 601 is installed into the installation space, the elastic support component is compressed to generate a supporting force extending along the axis of the gas cylinder 601. When the gas cylinder 601 is rotated and installed in the installation space, the bottom of the gas cylinder 601 has a pushing force to maintain a pre-pressure between the gas cylinder 601 mouth and the installation screw. In practice, due to the miniaturization design requirements of the water purifier equipment, the gas cylinder installation space is very limited. Traditional installation methods often require both hands to hold the bottle body and push it towards the installation screw, while simultaneously rotating the bottle body slowly for installation. By employing the elastic support component design described above in this embodiment, when the gas cylinder 601 enters the installation space, the bottom of the gas cylinder will contact and press down on the elastic support component, causing the elastic support component to generate a pushing force corresponding to the direction of the installation screw hole, i.e., the axial extension direction of the gas cylinder 601. This alleviates the influence of the gas cylinder 601's own weight, greatly reducing the pressure on a person to hold and rotate the cylinder. Even with sufficient pushing force, it is possible to rotate the cylinder with one hand, effectively reducing labor intensity, improving installation efficiency, and achieving labor-saving and convenient installation. To achieve even better labor-saving effects, preferably, as follows... Figure 55 As shown, the gas cylinder 601 can be set to a vertical installation state. The installation screw on the gas injection adapter 602 corresponds to a vertically extending threaded screw. The pushing force of the elastic support component is vertically upward. The vertical installation method not only helps to give full play to the pushing effect of the elastic support component, but also makes it easier to align the installation position. At the same time, it helps to ensure the safety of the gas in the gas cylinder 601 under long-term use.

[0113] In practice, to fully overcome the installation inconvenience caused by the self-weight of the gas cylinder 601 to be installed, as a preferred implementation scheme, before the gas cylinder 601 is screwed into the installation screw hole and installed in place, the elastic restoring force of the elastic support component is still not less than the self-weight of the gas cylinder 601; after the gas cylinder 601 is installed in place, the elastic support component still has the elastic restoring force, thereby fully overcoming the pressure of the self-weight of the gas cylinder 601 and realizing labor-saving installation.

[0114] One possible implementation scheme as a flexible support component is, for example... Figure 56As shown, the elastic support component includes a cylindrical gas cylinder support base 606 and an elastic element 610 installed inside the gas cylinder support base 606. The top of the elastic element 610 supports the gas cylinder 601, and during the installation of the gas cylinder 601, the top surface of the elastic element 610 never exceeds the gas cylinder support base 606, allowing the top surface of the elastic element 610 to directly contact and support the bottom of the gas cylinder 601. Furthermore, a gas cylinder support plate 607 can be provided on the top of the elastic element 610. The gas cylinder support plate 607 contacts the bottom surface of the gas cylinder 601 for support, increasing the support contact area and support stability. To ensure the stability of the direction of the elastic thrust, the gas cylinder support plate 607 is further optimized by providing a guide element that cooperates with the gas cylinder support base 606. The guide element restricts the movement of the gas cylinder support plate 607 within the gas cylinder support base 606 to only along the axial direction of the gas cylinder 601. Specifically... Figure 55 As shown, at least one set of outwardly protruding guide rails 608 can be provided on the side of the gas cylinder support 606. The guide rails 608 have guide grooves. At least one set of guide blocks 609 that cooperate with the guide grooves are provided on the side of the gas cylinder support plate 607. The guide blocks 609 are embedded in the guide grooves inside the guide rails 608. Both the guide blocks 609 and the guide rails 608 extend along the axial direction of the gas cylinder 601, thereby achieving precise guidance of the direction of the top thrust and preventing directional deviation.

[0115] In practice, the elastic element 610 can adopt various elastic structures, such as the most common column spring, and more preferably, such as... Figure 56 The conical helical spring used in this embodiment is characterized by a smaller cross-section at the bottom fixed end and a larger cross-section at the top support end, which maintains a larger support range for the pushing force and enhances support stability. Furthermore, the conical helical spring under compression has a smaller overall height than ordinary columnar springs due to its conical design, making it more suitable for situations where the installation space of gas cylinders is limited and meets the requirements for miniaturization of the entire water purification equipment.

[0116] The water purifier provided in this embodiment also has the gas cylinder mounting assembly described above. The mounting frame of the gas pumping module is located inside the water purifier, and a side wall cover is provided on the outside of the gas cylinder mounting space to close the space. The side wall cover and the gas cylinder mounting frame are detachably connected, such as by using a snap-fit ​​installation method. Specifically, the gas cylinder mounting assembly is located on one side of the water purifier in the left-right width direction, and the side wall cover on the outside of the gas cylinder mounting space serves as part of the water purifier's exterior panel. When it is necessary to replace the gas cylinder 601, the side wall cover can be opened directly for operation, which is very convenient.

[0117] In conjunction with the foregoing embodiments, in this embodiment of the water purifier, the filter module 903 is preferably positioned in the middle area of ​​the water purifier, and the gas cylinder mounting assembly is located on one side of the water purifier's width direction. The water cup connector 604 in the gas cylinder mounting assembly extends towards the front of the water purifier, and the mounting opening of the gas cylinder mounting space faces one edge of the water purifier's width direction. This allows for installation of the gas cylinder 601 from the side position in the width direction, providing ample external operating space and facilitating the removal and placement of the gas cylinder 601. Furthermore, the filter module 903 has a raw water tank 1 and a purified water tank 2 arranged side-by-side along the width direction on its rear side; the gas cylinder 601 and the raw water tank 1 are on the same side in the width direction, preferably on the right side. In this embodiment, the raw water tank 1 can be directly removed for adding or pouring water. Similarly, as a component that needs to be removed and placed multiple times, placing the gas cylinder 601 and the raw water tank 1 on the right side better suits the user's operating habits and facilitates force application.

[0118] Example 9

[0119] Combination Figures 59-64 This embodiment also provides a power motor mounting structure for a water purifier, including a power mounting frame 401. The power mounting frame 401 has a motor mounting space, and a partition plate 402 is provided on the upper side of the motor mounting space. The filter power pump 400 is detachably mounted below the partition plate 402 via a connecting frame 403. The lower side of the motor mounting space has an opening through which the filter power pump 400 can be placed into the motor mounting space. At least one opening is provided on the frame around the motor mounting space as a maintenance window. The power mounting frame 401 has a pipe opening for connecting a water supply pipe at a position corresponding to the pipe end of the filter power pump 400. The pipe end is used to connect the filter module 903 of the water purifier and the raw water, respectively.

[0120] It should be noted that the filter pump 400, as an essential component of RO reverse osmosis water purifiers, is traditionally installed by mounting its bottom directly onto the base of the purifier. After all other components are installed, the base is then installed, and performance testing is performed. This method has several drawbacks. First, the vibrations generated by the filter pump 400 during operation are transmitted to other internal components through the base, causing resonance, resulting in significant noise and poor overall stability. Second, performance testing can only be performed after the entire base is installed. If the filter pump 400 malfunctions and needs replacement, the entire base must be removed to access the pump, making the process cumbersome and time-consuming.

[0121] In this embodiment, the filter cartridge power pump 400 is completely detached from the outer casing and base of the water purifier. An independent motor mounting space is provided on the internal power mounting bracket, allowing the filter cartridge power pump 400 to be mounted upside down on the partition base plate 402 from bottom to top. This facilitates direct installation and removal while isolating the filter cartridge power pump 400 from other functional components within the water purifier. After the entire unit is installed, the filter cartridge power pump 400 maintains a certain gap between itself and the surrounding outer casing and base of the water purifier within the mounting space, significantly reducing the resonance effect of the filter cartridge power pump 400 during operation and achieving stable, low-noise operation of the water purifier. Furthermore, at least one open window for maintenance is provided on the frame around the filter cartridge power pump 400. Figure 59 As shown, the filter element power pump 400 has open windows at the front and rear ends and on the left side for maintenance. After the filter element power pump 400 and other functional components are installed, the performance of the filter element power pump 400 can be directly tested through the open windows without installing the entire machine housing and base. The filter element power pump 400 and the partition plate 402 are detachably installed. If the filter element power pump 400 is found to be malfunctioning, it can be removed for repair or replacement in a timely manner, which is convenient. After all functional components are tested and found to be operating normally, the entire machine housing and base can be installed, avoiding the cumbersome process of disassembling and assembling the housing, saving time and effort.

[0122] To further reduce the vibration impact of the filter element power pump 400, an optimized solution is to include an annular fitting portion 404 that is fitted to the wall of the filter element power pump 400. The annular fitting portion 404 has flat mounting portions 406 extending from its two side edges. The flat mounting portions 406 are used to mate with the partition base plate 402, thereby fixing the filter element power pump 400 below the partition base plate 402. Using the annular fitting portion 404 to fit against the wall of the filter element power pump 400 enhances the installation and fixation of the connecting frame 403 and the filter element power pump 400. Various common fixing methods such as welding, riveting, and bolting can be used. Using the flat mounting portions 406 to mate with the partition base plate 402 maintains planar contact and enhances connection stability.

[0123] As a more optimized implementation of the connector 403, combined with Figure 63 and Figure 64As shown, in this embodiment, the connecting frame 403 includes an annular fitting portion 404 that is fitted to the wall of the filter element power pump 400. Symmetrically arranged on both sides of the annular fitting portion 404 are extended transition portions 405. The outer ends of the extended transition portions 405 on both sides are respectively provided with planar mounting portions 406. The annular fitting portion 404, the extended transition portions 405, and the planar mounting portions 406 are all smoothly connected. The extended transition portions 405 gradually extend upwards and outwards in a direction away from the annular fitting portion 404, so that the height of the planar mounting portion 406 is not lower than the top surface height of the annular fitting portion 404. The planar mounting portion 406 is used to mate with the partition substrate 402 for installation. Figure 62 As shown, this design not only helps to enhance the structural strength of the connecting frame 403 and achieve a tight connection between the connecting frame 403 and the partition plate 402, but also allows a certain gap to be maintained between the top of the filter element power pump 400 and the partition plate 402 to avoid large-area contact, thereby reducing the resonance effect.

[0124] In practice, based on various designs of the connecting frame 403, a design that can further reduce resonance transmission is to provide a damping pad 407 between the planar mounting part 406 and the partition plate 402. The damping pad 407 can be made of various commonly used materials such as rubber and nylon, which can further reduce the vibration impact of the filter element power pump 400, so that there is a certain gap between the planar mounting part 406 and the partition plate 402, which enhances the installation stability and further reduces the installation contact area.

[0125] As one of the possible implementation methods in practice, the planar mounting portion 406 may be provided with multiple mounting points at intervals along the length extension direction of the filter element power pump 400. These mounting points are detachably connected to the partition plate 402. This multi-point connection ensures a stable connection while reducing the contact area between the connecting frame 403 and the partition plate 402, thereby further weakening the vibration transmission effect of the filter element power pump 400. Furthermore, each mounting point is equipped with a shock-absorbing pad 407 for vibration damping. Specifically, the planar mounting portion 406 and the partition plate 402 can be fastened together with bolts. Since the filter element power pump 400 is installed in an inverted manner, the bolts can also be fastened by passing through the planar mounting portion 406 and the partition plate 402 sequentially from bottom to top. Specifically, a gasket mounting hole can be provided on the planar mounting portion 406, and a shock-absorbing gasket 407 is disposed within this gasket mounting hole, extending beyond the upper and lower surfaces of the planar mounting portion 406. The shock-absorbing gasket 407 has a bolt connection hole in its center for the bolt to pass through. The shock-absorbing gasket 407 enhances the shock absorption effect and also helps to improve the tightness of the bolts.

[0126] This embodiment also provides a water purification device with the power motor mounting structure described above. The inlet of the filter power pump 400 is connected to the raw water of the water purification device, specifically, it can be connected to the raw water tank 1 in the above embodiment. The outlet of the filter power pump 400 is connected to the filter module 903 of the water purification device. Furthermore, the bottom support of the power mounting bracket 401 is detachably installed with respect to the base of the water purification device, and there is a certain height gap between the bottom of the filter power pump 400 and the base of the water purification device. As analyzed above, this design allows the filter power pump 400 to be separated from the main body housing and base, so that the main body housing and base can be installed after the performance test of the filter power pump 400 is completed, avoiding repeated disassembly and assembly of the housing and base. Moreover, the bottom of the filter power pump 400 remains suspended, preventing vibration from being transmitted through the main body base and causing resonance, ensuring that other components are not affected by the vibration of the filter power pump 400, and achieving long-term stable operation of the entire device.

[0127] The water purification device in this embodiment also provides cold water and has an internal cooling module 8. Specifically, a cooling mounting bracket 110 is provided on one side of the power mounting bracket 401. The cooling mounting bracket 110 has a space for installing the cooling module, and specifically, the upper part of the cooling mounting bracket 110 has an opening for placing and removing the cooling module 8. A partition plate is provided between the installation space of the filter element power pump 400 and the installation space of the cooling module. This not only improves the structural strength of the frame, but also further separates the filter element power pump 400 and the cooling module 8 from each other, thereby effectively preventing collision damage between the filter element power pump 400 and the cooling module 8 during transportation, and preventing motor vibration from affecting the operation of the cooling module 8.

[0128] To achieve a reasonable distribution of the various component modules within the water purification equipment, in this embodiment, the power mounting bracket 401 is divided into upper and lower mounting spaces by the partition substrate 402. The upper mounting space houses at least one pump body smaller than the filter cartridge power pump 400. Depending on the complexity of its functions, water purification equipment often requires multiple pump bodies, with the filter cartridge power pump 400, which powers the raw water filtration, having greater power, weight, and volume. Placing the lighter and smaller pump body in the upper space and the larger and heavier filter cartridge power pump 400 in the lower space enhances the stability of the structural distribution and achieves a centralized distribution of multiple pump components on the mounting bracket. Specifically, in practice, a water distribution transfer valve assembly 800 is installed in the upper mounting space. This assembly is used to distribute the purified water filtered by the filter cartridge module. The water distribution transfer valve assembly 800 is equipped with at least one power pump to distribute the filtered purified water to the corresponding functional modules. The volume and power of each power pump are smaller than the lower filter cartridge power pump 400. The structure of the water distribution transfer valve assembly 800 is as described in the above embodiment, wherein three power pumps are arranged sequentially along the length extension direction of the filter element power pump 400, and the extension direction of the power pumps is perpendicular to the extension direction of the filter element power pump 400. This not only facilitates the rational distribution of internal space and promotes the miniaturization of the whole machine, but also separates different water circuits, making the internal pipelines clearer and easier to maintain.

[0129] Example 10

[0130] Combination Figures 59-61 As shown, this embodiment further elaborates on the structure of the power mounting bracket 401. An edge plate 4012 extending in the front-rear direction is provided on the outer side of the partition base plate 402. The top surface height of the edge plate 4012 is lower than the top surface height of the partition base plate 402, thus forming a recessed step on the outer side of the partition base plate 402. This recessed step is used to place a certain purified water delivery pipe in the purified water distribution valve assembly, ensuring that the pipe distribution does not affect the installation distribution of other components on the partition base plate 402. Specifically, the purified water distribution valve assembly includes a transfer valve assembly body 800, on which at least one set of water transfer pumps is installed, such as... Figure 60 As shown, the transfer valve assembly body 800 adopts the structure described in the above embodiment. In this embodiment, a water outlet pipe connected to the water faucet pipe with a heating element is placed on the recessed step formed on the outer side of the partition base plate 402, that is, a water outlet pipe connected to the second outlet 812 as described in the above embodiment is placed there. Furthermore, a locking frame 4013 is provided on the outer step surface of the partition base plate 402. The locking frame 4013 is located above the edge plate 4012 and is used to lock and limit the surface of the water outlet pipe installed on the edge plate 4012. The locking frame 4013 is preferably designed as a downward-opening arc-shaped structure to achieve a tight fit and locking of the pipe surface.

[0131] To further ensure stable installation and support of multiple power pump bodies on the transfer valve assembly body 800, a support plate seat 4016 extending along the length direction is provided on the right edge of the partition base plate 402 opposite to the edge plate 4012. Multiple upwardly extending support plates 4014 are spaced apart on the support plate seat 4016. Figure 59 and Figure 60 As shown, one end of each water transfer pump extends into the interval area between adjacent support plates 4014. Furthermore, the partition base plate 402 is also provided with a support rib 4017, which is distributed parallel to the support plate seat 4016 and is located between the support plate seat 4016 and the edge plate 4012. Each water transfer pump is located above the support rib 4017, and an arc-shaped groove adapted to the outer wall of the pump body can be opened on the support rib 4017 to stabilize the pump body.

[0132] This embodiment also provides a water purification device with a power mounting bracket 401 as described above. The filter cartridge power pump 400 is installed in the lower mounting space of the power mounting bracket 401 and is detachably fixed to the partition base plate 402 via a connecting plate. The upper mounting space of the power mounting bracket 401 houses the transfer valve assembly body 800. This not only facilitates a rational distribution of internal space and promotes the miniaturization of the entire machine, but also separates different water paths, making the internal piping clearer and facilitating individual maintenance.

[0133] In practice, the top of the power mounting bracket 401 is closed by the water storage tank seat 3. The water storage tank seat 3 is detachably connected to the power mounting bracket 401. The water storage tank seat 3 has a raw water tank 1 and a clean water tank 2. Both the raw water tank 1 and the clean water tank 2 are detachably connected to the water storage tank seat 3 below, so that the water tanks can be taken out and put in at any time. The water storage tank seat 3 also realizes the separation of the water tank and the lower pump body pipeline.

[0134] The water purification equipment also includes a base 5 and an outer casing. The bottom of the power mounting bracket 401 is detachably connected to the base 5. Specifically, the four corners of the bottom of the power mounting bracket 401 each have a support leg 4011, which is used to detachably connect to the base 5. The sides of the power mounting bracket 401 are also detachably connected to the circumferential outer casing. This allows for a comprehensive test of the pump's performance after the filter power pump 400 is installed, but before the base 5 and outer casing are installed, avoiding repeated disassembly and reassembly of the base 5 and casing and simplifying installation and maintenance operations.

[0135] Example 11

[0136] Combination Figures 57-59As shown, this embodiment also provides a refrigeration mounting rack 110 for the water purifier. The refrigeration mounting rack 110 has an installation space inside for accommodating the refrigeration module 8, and the top of the refrigeration mounting rack 110 has an opening for the refrigeration module 8 to be placed in and out. The bottom of the refrigeration mounting rack 110 is provided with a connecting component located in the installation space. The connecting component is used to support and detachably connect the refrigeration module 8. The bottom of the refrigeration mounting rack 110 is also provided with a connecting support 1107, which is used to detachably connect to the base 5 of the water purifier. The refrigeration mounting rack 110 has connectors around its perimeter for detachably connecting to the exterior panel of the water purifier. One side wall of the refrigeration mounting rack 110 has an opening space for placing the exhaust fan mounting bracket 1101. Preferably, the opening space for placing the exhaust fan mounting bracket 1101 is on the rear side wall of the refrigeration mounting rack 110. In practice, the exhaust fan mounting bracket 1101 can also be provided on other sides as needed. The connecting components for the cooling module 8 at the bottom of the cooling mounting bracket 110 can take various forms. For example, multiple sets of fixing posts 1103 can be set around the bottom of the cooling mounting bracket 110. The fixing posts 1103 are located within the installation space. The top of the fixing posts 1103 has a slot, and the slot has a connecting hole. In practice, the bottom of the cooling module 8 is provided with mounting posts that mate with the slots at the top of the fixing posts 1103, so that the bottom of the cooling module 8 is accurately positioned by embedding it into the fixing posts 1103. Then, fastening bolts can be used to pass through the connecting holes from the bottom of the fixing posts 1103 and fasten them into the mounting posts at the bottom of the cooling module 8, so as to achieve detachable installation and limit the movement of the cooling module 8. Alternatively, a snap-fit ​​structure can be set on the fixing posts 1103 to achieve snap-fit ​​connection with the bottom of the cooling module 8. Or, a snap-fit ​​structure can be directly set around the bottom of the cooling mounting bracket 110 for detachable installation of the cooling module 8. Furthermore, to enhance structural stability, reinforcing rib seats 1106 can be connected between adjacent sets of fixed columns 1103. For example, in this embodiment, the reinforcing rib seats 1106 are connected between two sets of fixed columns 1103 located on the same side in the left-right direction. Similarly, the connecting support 1107 can also be bolted to the base 5 of the entire unit. Multiple bolt fastening positions can be provided at the top and bottom of the refrigeration mounting bracket 110 for mounting to the exterior panel. Alternatively, in practice, a snap-fit ​​structure can be selected for detachable connection.

[0137] In this embodiment, the top of the refrigeration mounting bracket 110 is designed to allow the refrigeration module 8 to enter and exit from above and below. The refrigeration module 8 is fixed by the bottom connecting component, which facilitates the installation and removal of the refrigeration module 8. A special refrigeration mounting bracket 110 is used to place the refrigeration module 8. The refrigeration mounting bracket 110 is detachably connected to the water purifier base and the exterior panel. The installation and maintenance of the refrigeration module 8 can be completed before the base and exterior panel are installed. Finally, the base and exterior panel are installed. Compared with the traditional method of installing the refrigeration module 8 on the equipment base, it can avoid the need to repeatedly disassemble and reassemble the base when problems occur during maintenance, which facilitates the quick installation and maintenance of the equipment.

[0138] For the refrigeration module 8, providing sufficient ventilation and heat dissipation is crucial. Therefore, exhaust fans are often installed in the water purifier for exhaust heat dissipation. In this embodiment, the exhaust mounting bracket 1101 for installing the exhaust device is preferably located on the rear wall of the refrigeration mounting bracket 110. To improve the positional stability of the exhaust mounting bracket 1101, the upper part of both sides of the frame on the rear wall of the refrigeration mounting bracket 1100 has a support plane 1105 for supporting the exhaust mounting bracket 1101. The space between the two sides of the frame on the rear wall is for the exhaust mounting bracket 1101 to extend downward. In practice, the rear side of the refrigeration module 8 is equipped with heat dissipation fins, and the exhaust mounting bracket 1101 is fixedly installed on the heat dissipation fins. Exhaust devices such as fans are installed on the frame. The upper part of the exhaust mounting bracket 1101 is provided with a contact plane that mates with the support plane 1105 to achieve stable support on the support plane 1105 and maintain the stability of the installation. Furthermore, reinforcing ribs are connected between the bottom of the two sides of the frame on the rear wall of the refrigeration mounting bracket 110 to enhance the structural stability of the mounting bracket.

[0139] In this embodiment, the refrigeration mounting bracket 110 is located in the lower rear area of ​​the main body of the water purifier. Specifically, a filter module 903 is provided in the middle of the water purifier. A purified water tank 2 and a raw water tank 1 are arranged sequentially along the left and right width direction on the upper rear side of the filter module 903. The lower rear side of the filter module 903 is where the refrigeration mounting bracket 110 and the power mounting bracket 401 for installing the power pump body structure are located. To achieve safe separation of the refrigeration module 8 from other functional modules, a front partition 1102 is provided on the front wall of the refrigeration mounting bracket 110, and a partition plate A4015 is provided on the side wall of the refrigeration mounting bracket 110 that is not facing the exterior panel in the left and right direction. Both the front partition 1102 and the partition plate A4015 are used to separate the cold tank installation space from other installation spaces of the water purifier. The front partition 1102 is also provided with a clearance groove for pipeline connection.

[0140] To improve the stability and weight reduction of the frame structure, the refrigeration mounting bracket 110 can be optimized by providing multiple layers of stiffening plates along its length on all four sides of the frame. The multiple layers of stiffening plates are spaced apart to form a grid structure. This structure can effectively reduce the weight of the frame while ensuring its strength and stability.

[0141] This embodiment also provides a water purification device, which includes a refrigeration mounting bracket 110 as described above, and a base 5. The base 5 has a ventilation seat 1104 with an air inlet hole communicating with the outside. The base 5 is detachably connected to the bottom of the refrigeration mounting bracket 110, specifically through a connecting support 1107 at the bottom of the refrigeration mounting bracket 110, which can be fastened with bolts or clips. Correspondingly, an exhaust mounting bracket 1101 is supported on the rear wall of the refrigeration mounting bracket 110, and an exhaust device such as a fan is provided inside the exhaust mounting bracket 1101. There is a certain height gap between the bottom of the exhaust mounting bracket 1101 and the base 5, so that the exhaust device is located at the upper part of the rear wall of the refrigeration mounting bracket 110. The water purification equipment also includes an exterior panel, which is detachably connected to the refrigeration mounting bracket 110. The exterior panels connected to the side walls of the refrigeration mounting bracket 110 are all equipped with exhaust channels that communicate with the internal space. For example, the exterior panels installed on the outer and rear walls of the refrigeration mounting bracket 110 can be in the form of a grid plate. In addition to the exhaust device on the rear wall of the refrigeration mounting bracket 110, the outer walls on the left and right sides are designed with an open type, which communicates directly with the outside through the exhaust channels on the exterior panels, further promoting sufficient heat dissipation.

[0142] This embodiment adopts a bottom-intake and rear-top exhaust method, which can fully ensure heat dissipation and is suitable for the product application scenario without affecting other settings. Furthermore, the ventilation seat 1104 protrudes upward inside the base 5, so that there is a certain height ventilation gap 1109 between the bottom surface of the ventilation seat 1104 and the bottom surface of other parts of the base 5, so as to achieve sufficient air intake and heat dissipation.

[0143] In this embodiment, the top opening of the refrigeration mounting bracket 110 is closed by the water storage tank base 3. The refrigeration mounting bracket 110 and the water storage tank base 3 are detachably connected. The raw water tank 1 and the purified water tank 2 are detachably installed on the water storage tank base 3. Specifically, the refrigeration module 8 and the raw water tank 1 can be located on the same side in the left-right direction, that is, the raw water tank 1 is located above the refrigeration module 8. The water storage tank base 3 is used to achieve a safe separation between the refrigeration module 8 and the water tank, promoting the safe separation of water and electricity.

[0144] Example 12

[0145] Combination Figures 65-71 As shown, this embodiment also provides a water collection box for a drinking water device, such as... Figure 1As shown, the water collection box 700 is located below the water tap of the water purifier. The water collection box 700 includes a water collection box body 710 and a cover plate 720. The water collection box body 710 has a water collection cavity for collecting water. The cover plate 720 is used to cover the water collection box body 710 and has a drain hole communicating with the water collection cavity. The cover plate 720 and the water collection box body 710 are detachably connected. The cover plate 720 has a water receiving area 721 and a pressing area 722 along the front and rear directions, respectively. The rear direction is the direction in which the water collection box 700 is installed with the water purifier body. The drain hole is located in the water receiving area 721 to collect water dripping from the water inlet of the water purifier. The pressing area 722 is used for pressing to remove the cover plate 720 by hand.

[0146] Combination Figure 66 As shown, the water collection box 710 has a front support 715 and a rear support 714 along its front-to-back direction to stably support the cover 720. The rear support 714 and the cover 720 are in a movable fit. Through this design, the cover 720 is configured such that when the pressing area 722 is pressed down, the cover 720 can rotate around the rear support 714, causing one end of the cover 720's water-receiving area 721 to rotate upwards and detach from the water collection box 710. When the water needs to be cleaned, using the lever principle, the pressing area 722 can be pressed directly, causing the cover 720 to rotate around the support point of the rear support 714. After one end of the water-receiving area 721 is lifted upwards, the cover 720 can be directly removed from the lifted end, thus cleaning the internal water. Furthermore, the user does not need to insert their hand into the water during the removal of the cover 720. Compared to the traditional design that requires manual prying out of the cover, this effectively improves the user experience, and the timing of cleaning is not affected by the water temperature. The entire operation is simple and convenient.

[0147] As one embodiment of the movable cooperation between the rear support 714 and the cover plate 720, such as Figure 66 As shown, the cover plate 720 is provided with a mounting portion 723; the mounting portion 723 has a locking groove 724 that corresponds to the rear support portion 714 of the water collection box body 710. The locking groove 724 is located on the front side of the pressing area 722. When the pressing area 722 is pressed, the cover plate 720 rotates and tilts up by the movable cooperation between the locking groove 724 and the rear support portion 714. More preferably, the locking groove 724 is a V-shaped groove with an opening that gradually increases from top to bottom and is open at the bottom. The top of the rear support portion 714 is embedded in the V-shaped groove, and the locking groove 724 can rotate around the rear support portion 714. By utilizing the cooperation between the locking groove 724 and the rear support portion 714, both the limiting and stable support of the cover plate 720 can be ensured, while also ensuring the flexibility of the cover plate 720's rotation. In practice, the mounting portion 723 can be a part that extends beyond the thickness of the cover plate 720 itself, such as... Figure 66The portion shown is the part that protrudes downward beyond the thickness of the cover plate 720. Alternatively, a locking groove 724 can be formed within the cover plate 720 itself, so that the portion of the cover plate 720 where the locking groove 724 is located becomes the mounting part 723.

[0148] As another embodiment where the rear support 714 and the cover plate 720 are movable together, such as Figure 70 and Figure 71 As shown, the bottom surface of the cover plate 720 is provided with a downwardly extending mounting portion 723. When the cover plate 720 is placed on the water collection box 710, the mounting portion 723 is located in front of the rear support portion 714. The mounting portion 723 can extend vertically downward along the bottom surface of the cover plate 720 and be distributed perpendicular to the bottom surface of the cover plate 720; or it can be gradually inclined downward in a direction away from the rear support portion 714. In this way, the angle formed between the mounting portion 723 and the bottom surface of the cover plate 720 is the engaging groove that movably cooperates with the rear support portion 714. The mounting portion 723 forms a stop plate structure located in front of the rear support portion 714, which can also satisfy the limiting and supporting effect of the cover plate 720, and allow the cover plate 720 to rotate around the rear support portion 714. Compared with the method of opening a V-shaped groove in the mounting portion 723, the structure of the mounting portion 723 can be further simplified.

[0149] Secondly, as a variety of implementation methods available in practice, the cover plate 720 and the rear support part 714 can also be rotated by using a hole-shaft mating direction. For example, a bottom through hole structure can be opened on the cover plate 720, and the rear support part 714 can be set as a shaft structure passing through the through hole. The hole-shaft structure can be used to support the cover plate 720, while allowing the cover plate 720 to be pressed and rotated around the rear support part 714.

[0150] Combination Figures 67-69 As shown, in this embodiment, the extension height of the rear wall 712 of the water collection box 710 is lower than the extension height of the rear support 714. When the cover plate 720 is placed on the water collection box 710, there is a certain gap between the top of the rear wall 712 and the bottom surface of the pressing area 722, so that the pressing area 722 can be pressed down, causing one end of the water receiving area 721 of the cover plate 720 to rotate upward and separate from the water collection box 710.

[0151] As different embodiments of the rear support 714, the rear support 714 can be installed on the bottom wall of the water collection box 710, or on the four sides of the water collection box 710, such as connecting to at least one side wall of the water collection box 710; or simultaneously connecting to both the bottom wall and side walls of the water collection box 710, and extending in the left-right width direction within the water collection box 710. The extension width of the rear support 714 is equal to or less than the width of the water collection cavity within the water collection box 710. The width direction mentioned here refers to the left-right direction perpendicular to the front-back direction in the figure. In practice, the rear support 714 can be a one-piece structure or a multi-segment structure. Its width can extend to both sides of the water collection box 710, or it can be less than the width of the water collection cavity. Its connection end with the water collection box 710 can be connected to at least one side wall or to the bottom wall, thus achieving stable support and movable cooperation for the cover plate 720. Figure 66 The rear support 714 is a one-piece plate structure with the same width as the water collection cavity. It extends to both ends of the rear support 714 and connects to the side walls of the box and the bottom of the water collection box 710. Alternatively, the rear support 714 can be set as a shaft-like structure connected to the side wall of the water collection box 710 and rotates with the corresponding through hole on the cover plate 720.

[0152] In this embodiment, the front support portion 715 within the water collection box 710 works in conjunction with the rear support portion 714 to provide stable support for the cover plate 720. Similar to the design of the rear support portion 714, the front support portion 715 can be installed on the bottom wall of the water collection box 710, or on the four sides of the water collection box 710, such as connecting to at least one side wall of the water collection box 710; or simultaneously connecting to both the bottom and side walls of the water collection box 710. The extension width of the front support portion 715 is equal to or less than the width of the water collection cavity within the water collection box 710. The front support portion 715 can be a one-piece structure or a multi-segment structure, as long as it provides a stable support point for the front side of the cover plate 720. Figure 67 As shown, outwardly protruding support points or support columns can be provided on the inner walls of both sides of the water collection box 710 as front support parts 715. As a different implementation option, a part of the box wall around the water collection box 710 can be directly used as the front support part 715 to support the cover plate 720. For example, at least a part of the front box wall of the water collection box 710 can be set as the front support part 715, and the front end of the cover plate 720 can be placed on the front box wall of the water collection box 710, or a support groove can be opened in a part of the front box wall of the water collection box 710 so that the front end of the cover plate 720 is at least partially embedded in the support groove.

[0153] To further enhance the stability of the cover plate 720, an auxiliary support member 716 can be further optimized within the water collection box 710. This auxiliary support member 716 works in conjunction with the rear support part 714 and the front support part 715 to provide multi-point stable support for the cover plate 720. In this embodiment, the auxiliary support member 716 can be located in the area between the rear support part 714 and the front support part 715. Similar to the design of the rear support part 714, the auxiliary support member 716 can also adopt an integrated or multi-segment design. Its installation position and extension width will not be described further. Preferably, to facilitate cleaning of the inside of the water collection chamber, both the front support part 715 and the auxiliary support member 716 adopt a support point or support column structure that protrudes outward from the inside of the water collection box 710.

[0154] In practice, alternatively, pads 711 may be provided at the four corners of the bottom of the water collection box 710 to keep the height of the water collection box 710 consistent with that of the drinking water equipment body.

[0155] This embodiment also provides a drinking water device, employing the water collection box 700 described in the above embodiment. The water collection box 700 is located below the water inlet of the drinking water device, and has a connecting part 713. It is installed onto the body of the drinking water device through the connecting part 713. As one different implementation, the water collection box 710 can be detachably connected to the body of the drinking water device. In this case, connecting buckles can be provided on the rear wall 712 or the side walls of the water collection box 710 as connecting parts 713, making it easy to directly remove the water collection box 710 to empty the collected water. As another implementation, the water collection box 710 can be fixedly connected to the body of the drinking water device. For example, the water collection box 710 and the base of the drinking water device are designed as an integral piece. In this case, the plane area where the water collection box connects to the body of the drinking water device serves as the connecting part 713, and the connecting part 713 can also serve as the rear wall 712 of the water collection box 710. The above design allows for multiple methods of cleaning accumulated water. The entire water collection box can be removed and the cover plate 720 can be taken off for cleaning, or the water collection box can be kept in its installed state and only the cover plate 720 can be removed for cleaning. The operation is convenient, and direct contact with accumulated water is avoided during the removal of the cover plate 720, thus improving the user experience.

[0156] Example 13

[0157] Combination Figure 72As shown, this embodiment also provides a water pipe distribution system for a water purifier, including a raw water tank 1, a filter module 903, and a purified water tank 2. The raw water tank 1 is connected to the filter module 903 via a raw water pipe 105b, and the filter module 903 is connected to the purified water tank 2 via a purified water pipe 204b. In practice, a one-way valve can be installed on the purified water pipe 204b. It should be noted that: in this embodiment, the bottom of the purified water tank 2 is provided with a water outlet, which serves as both a purified water inlet for receiving filtered purified water and a purified water outlet for supplying water to the distribution pipe 304b; and the distribution pipe 304b is provided with a water tank interface, a purified water interface, and an external interface. The distribution pipe 304b is connected to the purified water tank 2 via the water tank interface, connected to the purified water pipe 204b via the purified water interface, and distributes purified water through the corresponding external interface. The water purification tank 2 in this embodiment can adopt the water purification tank structure in the above embodiment, and the bottom of the water purification tank 2 can also be detachably installed on the water storage tank base. The water storage tank base is provided with a water outlet that corresponds to the water outlet at the bottom of the water purification tank 2. Both the water storage tank base and the water purification tank 2 are provided with a water stop valve. When the water purification tank 2 is placed on the water storage tank base, the water stop valve is opened to supply water. When the water purification tank is removed from the water storage tank base 3, the water stop valve is closed to prevent water flow.

[0158] Depending on the different functions of the water purifier, different external interfaces can be set on the distribution pipe 304b in practice to distribute purified water to different functional modules. For example, when only the cooling water function exists, the distribution pipe 304b is equipped with an external interface connected to the cooling module 8. When only the room temperature water and hot water functions exist, the distribution pipe 304b is equipped with an external interface connected to the outlet branch pipe 305b, which is connected to the water tap. The outlet branch pipe 305b is equipped with a heating element, and the room temperature water outlet and hot water outlet on the water tap share the same outlet. When room temperature water is needed, the heating element does not heat the purified water, and the water tap dispenses room temperature water directly. When hot water is needed, the heating element is activated to heat the purified water.

[0159] To achieve comprehensive functionality of the water purification device in this embodiment, the external interface on the distribution pipe 304b includes both an interface connected to the refrigeration module 8 and an interface connected to the outlet branch pipe 305b. The outlet branch pipe 305b is connected to a water tap and is equipped with a heating element. A self-priming pump 2 is installed on the pipe connecting the distribution pipe 304b and the refrigeration module 8, and a self-priming pump 1 is installed on the outlet branch pipe 305b. The outlet of the heating element is connected to a water vapor separator via a pipe. The water vapor separator is equipped with an exhaust port and a water outlet. Temperature sensors are installed at the inlet and outlet ends of the heating element. The water outlet serves as both a room temperature water outlet and a hot water outlet. When the heating element heats up, hot water flows out of the outlet; when the heating element does not heat up, room temperature water flows out of the outlet. The outlet of the refrigeration module 8 is connected to a cold water outlet via a cold water pipe 402b, and the cold water outlet is a separate outlet. In practice, all water outlets are located inside the water tap.

[0160] In this embodiment, through the coordinated design of multiple interfaces on the distribution pipe 304b, the filtered purified water is not directly connected to the purified water tank 2. Instead, it is first connected to the distribution pipe 304b, and then connected to the purified water tank 2 through the water tank interface on the distribution pipe 304b. When the purified water tank 2 is placed on the water storage tank base, the purified water can either flow into the purified water tank 2 for storage or flow directly to the heating element or the cooling module 8. When the purified water tank 2 is removed, the filtered purified water remains connected to the distribution pipe 304b, and the water stop valve in the water tank base is closed to prevent water from overflowing. Instead, the purified water flows directly to the heating element or the cooling module 8 through the corresponding interface on the distribution pipe 304b. This allows the drinking water equipment to still function normally after the purified water tank 2 is removed, greatly improving the ease of use of the equipment.

[0161] A further optimized design in this embodiment is that the filter module specifically adopts an RO reverse osmosis filter element. A booster pump is correspondingly installed on the raw water pipeline 105b, which is used to pump the raw water in the raw water tank 1 to the filter module 903. The wastewater outlet of the filter module 903 is connected to the raw water tank 1 through the wastewater pipeline 203b, which is equipped with a wastewater valve. In this embodiment, the water system provides more sufficient power for raw water filtration through the booster pump. In conjunction with the design of the self-priming pump one and self-priming pump two at the back end, the pump operation program can be controlled to achieve a constant speed and flow rate of water output from the drinking water equipment. This facilitates more precise temperature control and improves the control accuracy of the drinking water output temperature and single-batch water volume.

[0162] To further improve water utilization, a more optimized implementation scheme is as described in the aforementioned embodiment: the raw water tank 1 is equipped with an overflow baffle to divide the inner cavity of the raw water tank 1 into a concentrated water zone and a raw water zone; the bottom of the raw water zone is connected to the filter module through the raw water pipeline 105b; the outlet of the wastewater pipeline 203b is connected to the bottom of the concentrated water zone. That is, the initial raw water is stored in the raw water tank 1 to supply water to the filter module 903 for filtration. The wastewater generated after filtration by the filter module 903 flows back to the concentrated water zone through the wastewater pipeline 203b. The top of the overflow baffle is equipped with an overflow port. When the returned wastewater reaches a certain height, it overflows into the raw water zone through the overflow port for repeated filtration and utilization, thereby effectively improving the utilization rate of raw water.

[0163] To enable the testing of both raw water and filtered water quality, a preferred design in practice is to install water quality analyzers on both the raw water pipeline 105b and the distribution pipeline 304b. During water use, to maintain further purification, UV sterilizers are installed on the cold water pipeline 402b and the outlet branch pipe 305b, achieving flow-through disinfection and purification to improve water quality. For convenient and timely monitoring of water levels in the tanks, a further optimized design includes water level sensors in both the raw water tank 1 and the purified water tank 2. The raw water tank 1 is prompted to add raw water when the water level drops to a certain level; while the purified water tank 2 is equipped with water level sensors to monitor extreme high and low water levels. When the water level is low, the sensor prompts for continued water supply to continue purification; when the water level reaches a high level, the sensor indicates that further filtration and purification should cease to prevent water from overflowing the tank.

[0164] In conjunction with the aforementioned embodiments, to avoid a high TDS concentration in the first cup of water, this embodiment further proposes a solution for the water system. A flushing port is also provided on the distribution pipe 304b, which is connected to the inlet of the filter module 903. This port receives purified water from the water tank 2 and flushes it into the filter module 903. When flushing the filter module 903 is required, the remaining purified water in the water tank 2 is discharged into the filter module 903 through the flushing port. After the filter module 903 stops producing purified water, the purified water directly flushes the surface of the filter element and finally flows back to the concentrated water area of ​​the original water tank 1 via the wastewater pipe 203b. This effectively improves the problem of excessively high TDS in the first cup of water and enhances its quality.

[0165] To ensure the freshness of the water in the purified water tank 2, a preferred embodiment is to install a replacement interface on the distribution pipe 304b. This replacement interface is connected to the raw water tank 1 and is used to receive purified water from the purified water tank 2 into the raw water tank 1, specifically connected to the raw water area of ​​the raw water tank 1. In this case, residual purified water in the purified water tank 2 can be directly discharged into the raw water area of ​​the raw water tank 1 to achieve water replacement. When the purified water in the purified water tank 2 has been left for a long time and the user does not want to drink it directly, this method can be used to directly replace the purified water back into the raw water tank 1, thus avoiding water waste and maintaining the freshness of the purified water in the purified water tank 2. In practice, a flushing interface and the aforementioned replacement interface can also be installed on the distribution pipe 304b simultaneously, thereby achieving both the freshness function of the purified water tank 2 and the flushing effect on the filter element, improving water quality.

[0166] This embodiment also provides a water purification device, including a frame and a water system. The water system adopts the design described above. The raw water tank 1, the filter module, and the purified water tank 2 are all installed on the frame. This satisfies the requirement of multi-directional independent water supply to the purified water tank 2, the cooling module 8, and the heating element after filtration, while also ensuring the continuous connectivity of the water system. It can still be used normally even after the purified water tank 2 is removed. Furthermore, the control of multiple pumps helps to further improve the accuracy of quantitative and temperature control of the output water, which has significant advantages in use, provides users with a better user experience, and improves the convenience of use.

[0167] As a further optimization of the water purification equipment, the water purification tank 2 is arranged above the refrigeration module 8, with the bottom of the water purification tank 2 being higher than the top of the refrigeration module 8. This, combined with the inertia of the water flow, ensures that the purified water in the tank can always supply water to the refrigeration module 8 when the water purification tank 2 is configured, preventing the refrigeration module 8 from dry sucking. Even when the water purification tank 2 is removed, the purified water in the water purification pipe 204b can still enter the distribution pipe 304b through the water purification interface and directly supply water to the refrigeration module 8, which can also prevent the refrigeration module 8 from dry sucking and ensure the long-term stable operation of the equipment.

[0168] The present invention and its embodiments have been described above illustratively. This description is not restrictive and is merely one embodiment of the present invention, and is not actually limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
