Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] The present invention will be further described below with reference to the embodiments.

[0028] Example 1

[0029] 1 to 7 , the countertop multifunctional water purifier of this embodiment includes a main frame, which divides the interior of the water purifier into a filter element area, a water tank area, a refrigeration area, a water component area and a water receiving area, wherein the filter element area is located in the middle area of ​​the main frame, and a filter element module 903 is installed in the filter element area; the upper rear part of the filter element module 903 is the water tank area, and the raw water tank 1 and the clean water tank 2 are arranged side by side in the left and right width directions in the water tank area; the lower rear part of the filter element module 903 is provided with a refrigeration area and a water component area distributed side by side in the left and right width directions, and a refrigeration module 8 is installed in the refrigeration area for preparing cold water; water path components are installed in the water component area; a heating body for heating the filtered clean water is also provided on one side in the width direction of the filter element module 903, and when the heating body is started, the clean water is heated to the corresponding temperature to prepare hot water; when drinking room temperature water, the heating body is not started. In front of the filter module 903 is a water receiving area, which is equipped with a water tap 7. The water outlets of the cooling module 8 and the heating element are both connected to the water tap 7. Specifically, the water tap 7 can be provided with two water inlets, one for cold water and one for hot water, with the hot water inlet also serving as the normal temperature water inlet. This layout allows the functional modules to be independently separated, facilitating their installation and maintenance. The components are also compactly distributed, effectively saving internal space and promoting the miniaturization of the entire machine. The distribution of the modules generally conforms to the user's operating habits, making it highly convenient to use.

[0030] In order to further enrich the functions of the water purifier, an aeration area is further provided in the main frame, and an aeration module for injecting air to prepare sparkling water is provided in the aeration area. The aeration module is distributed on the other side of the filter element module 903 opposite to the heating body in the width direction, so that the various functional components of the water purifier are compactly arranged and tightly surrounded with the filter element module 903 as the axis.

[0031] As a practical design, to facilitate users' ability to clean or refill the water tanks at any time, both the raw water tank 1 and the clean water tank 2 are detachably connected to the main frame. They are located from right to left along the width of the upper rear portion of the filter module 903. The raw water tank 1, which is more frequently accessed, is located on the right, better suiting user preferences. Similarly, a more optimized design would place the air pump module to the right of the filter module 903, making it easier for users to remove and replace the gas cylinder when it runs out.

[0032] In this embodiment, the main frame has multiple mounting frames, including a filter element mounting frame for mounting the filter element module 903 in the filter element area, a water tank seat 3 provided on the upper rear side of the filter element mounting frame, and a refrigeration mounting frame 110 and a power mounting frame 401 provided side by side on the lower rear side of the filter element mounting frame, wherein the water tank seat 3 is correspondingly installed above the refrigeration mounting frame 110 and the power mounting frame 401, and the raw water tank 1 and the clean water tank 2 are respectively arranged on the water tank seat 3.

[0033] As a preferred solution for the water tank seat 3, as shown in Figure 5, the water tank seat 3 includes an L-shaped base and a side seat, wherein the base is correspondingly installed above the refrigeration mounting frame 110 and the power mounting frame 401, and the side seat is located on the side of the base close to the filter element mounting frame. The side seat separates the two water tanks from other modules located in the front area of ​​the water tank to prevent accidental leakage of water from affecting other components.

[0034] In this embodiment, the capacity of the raw water tank 1 is set to be larger than that of the clean water tank 2 to meet the demand for filtered water supply; and in order to facilitate the user to directly place the clean water tank 2 in the refrigerator to quickly prepare cold water, the clean water tank 2 is set to a size that can be placed in the side wall of the refrigerator door, with a width smaller than the raw water tank 1 and a depth larger than the raw water tank 1. Correspondingly, the base of the water tank seat 3 is provided with an interface for corresponding communication with the raw water tank 1 and the clean water tank 2, and the bottom plate heights of the base corresponding to the placement areas of the raw water tank 1 and the clean water tank 2 are different. The base height corresponding to the placement area of ​​the clean water tank 2 is lower than the base height corresponding to the placement area of ​​the raw water tank 1, so that the tops of the two water tanks remain flush.

[0035] In order to achieve the separate installation of water path components, as an optimal design scheme in practice, a partition substrate is provided in the power mounting frame 401, which divides the interior of the power mounting frame 401 into an upper installation space and a lower installation space. The water path components include a filter element power pump 400 for providing power for raw water filtration, and a water distribution transfer valve group 800 for distributing filtered clean water. The filter element power pump 400 and the water distribution transfer valve group 800 are respectively installed in different installation spaces. The filter element power pump 400 is used to pump the raw water in the raw water tank 1 into the filter element for filtration, and the water distribution transfer valve group 800 is used to distribute the filtered clean water so that it flows to the clean water tank 2 for storage, flows to the refrigeration module 8 to prepare cold water, and flows to the heating body pipeline to prepare hot water and normal temperature water. As a more preferred design, the filter element power pump 400 is installed in the lower installation space within the power mounting frame 401, and the water distribution transfer valve group 800 is installed in the upper installation space within the power mounting frame 401; the top of the filter element power pump 400 is detachably connected to the upper partition base plate via a connecting plate, and the bottom of the lower installation space is provided with an opening for the filter element power pump 400 to be taken in and out in the upper and lower directions. This design realizes the upside-down installation of the filter element power pump 400, which can be directly taken in and out of the lower installation space, and the bottom of the filter element power pump 400 remains suspended, while the upper part is installed on the partition base plate 402 via a connecting plate, without contacting the base of the whole machine or other functional modules, effectively reducing the transmission of motor vibration to other functional components to cause resonance, thereby ensuring the stable operation of each functional component and ensuring the noise reduction and stability of the water purifier during long-term use.

[0036] As an optimized design for the refrigeration mounting frame 110 and the power mounting frame 401, to further save space and materials, the refrigeration mounting frame 110 and the power mounting frame 401 share at least part of the mounting frame body, and a partition plate A4015 is provided on the relatively close wall surface of the two. The partition plate A4015 separates the filter element power pump 400 from the refrigeration module 8, further ensuring the safe separation of the water path from other components and effectively enhancing the structural stability of the mounting frame. A further optimized design is to provide at least one opening on the wall surface of the power mounting frame 401 as an inspection window to facilitate performance testing of the filter element power pump 400; an air inlet channel is provided at the bottom of the refrigeration mounting frame 110, and an air outlet channel is provided on at least one side wall surface. Specifically, an air outlet channel is provided on the rear side of the refrigeration mounting frame 110 to provide heat dissipation space for the internal refrigeration module 8.

[0037] To facilitate installation and maintenance of the water purifier, this embodiment provides 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 function, and then installing the exterior housing and base 5. This avoids repeated disassembly and assembly of the housing during maintenance, improving installation and maintenance efficiency.

[0038] Example 2

[0039] To more clearly demonstrate the comprehensive structural design of the water purifier in this application, the following describes the specific modular structural design of each area. First, the structure of the raw water tank 1 in this application is explained. This raw water tank 1 is primarily used in household water purifiers, but can also be used in industrial water purifiers. This raw water tank 1 can be fixedly installed in the water purifier or can be removable and removed from the water purifier. This embodiment uses a household water purifier as an example, and the raw water tank 1 adopts a movable, removable, independent structure.

[0040] As shown in Figures 8 to 15 , the raw water tank 1 provided in this embodiment includes a raw water region 16 for storing raw water and a concentrated water region 17 for storing concentrated water produced after purification by the filtration device. Of course, the raw water region 16 and concentrated water region 17 can be formed as a single unitary structure, i.e., by dividing a single unitary raw water tank 1 into two regions, or as two separate, independent tanks. In this embodiment, a single unitary structure is employed, with a partition plate 18 separating the water storage space of the raw water tank 1 into two independent chambers.

[0041] A raw water outlet 151 is located at the bottom of the raw water zone 16, connecting to the water purifier's filtration system. A concentrate inlet 152 is located at the bottom of the concentrate zone 17, connecting the concentrate zone 17 to the filtration system. The detachable raw water tank 1 is equipped with check valves at both the raw water outlet 151 and concentrate inlet 152 when installed in the water purifier. These valves automatically close when the raw water tank 1 is removed from the water purifier, preventing water from escaping.

[0042] The raw water tank 1 of this embodiment also features a reflux channel, connecting the raw water zone 16 and the concentrate zone 17. This channel is used to return concentrated water in the concentrate zone 17 to the raw water zone 16 after reaching a certain height. The reflux channel helps regulate the raw water recovery rate of the raw water tank 1. Depending on actual usage requirements, the reflux channel can be configured at different heights. When the concentrated water collected in the concentrate zone 17 reaches the reflux height, the water in the concentrate zone 17 can be returned to the raw water zone 16 for reuse. The reflux channel can be implemented in a variety of ways, such as through piping, connecting holes, connecting grooves, or even by directly designing the shape of the partition 18 between the concentrate zone 17 and the raw water zone 16. To ensure raw water recirculation, the reflux channel's reflux height is lower than the maximum water storage height of the concentrate zone 17 and the raw water zone 16. For example, the reflux channel's reflux height can be 1 / 3, 1 / 2, or 2 / 3 of the respective maximum water storage heights, with a preferred height exceeding 1 / 2 of the water storage height.

[0043] As shown in Figures 8 and 12 , the reflux channel in this embodiment is implemented by providing a reflux port 131 on the partition plate 18. After the raw water fills the water storage device, the water level can be lowered to the height of the reflux port 131 through continuous use, and the concentrated water area 17 and the raw water area 16 are separated. The water in the concentrated water area 17 rises due to the concentrated water filtered by the filter element and exceeds the height of the reflux port 131, and can overflow back to the raw water area 16 for reuse. Alternatively, the height of the raw water initially added to the raw water area 16 is lower than the reflux port 131. At this time, there is no water in the concentrated water area 17, and the water storage utilization rate of the water storage device is relatively low. Of course, a reflux hole can also be provided on the upper side of the partition plate 18 to form a reflux channel. The reflux port 131 can be a notch provided on the partition plate 18, and the reflux port can be a through hole provided in the partition plate 18. Alternatively, as shown in Figure 13 , the upper side of the partition plate 18 can be directly be formed into a beveled edge, with the lowest point of the bevel forming a reflux channel. When the water in the concentrated water zone 17 is higher than the lowest point of the beveled edge, reflux occurs. In addition to providing a reflux port 131 or reflux hole on the partition plate 18 , the height of the reflux port 131 or reflux hole on the partition plate 18 can be further adjusted. By adjusting the height of the reflux port 131 or reflux hole, the reflux height can be changed, thereby adjusting the raw water recovery rate as needed. Alternatively, the partition plate 18 can be detachably connected to the water tank wall, and the raw water recovery rate can be adjusted by directly plugging in partition plates 18 of different heights.

[0044] Special design is required. As shown in Figure 10, when viewing the interior of the raw water tank 1 from above (looking down), the concentrate inlet 152 is located at the bottom of the concentrate zone 17, away from the connection between the return channel and the concentrate zone 17. From the perspective of the figure, the return channel is located near the rear side of the tank, while the concentrate inlet 152 is located near the front side of the tank. This solution connects the concentrated water area 17 and the raw water area 16 at a certain height through a reflux channel. The concentrated water generated by the filtration device of the water purifier enters the concentrated water area 17 and is stored at a certain height, and then overflows into the raw water area 16 through the reflux channel. On the one hand, the concentrated water can be allowed to settle in the concentrated water area 17, and the dirtier dirt sinks to the bottom. The upper water quality is relatively clean and can be returned to the raw water area 16 for secondary use, thereby improving water utilization efficiency; on the other hand, the concentrated water inlet 152 of the concentrated water area 17 is relatively far away from the reflux channel, and the standing time of the concentrated water returning to the raw water area 16 through the reflux channel is increased, and the influence of the stirring effect of the water flow near the concentrated water inlet 152 is reduced, thereby further improving the water quality of the water returned to the raw water area 16, reducing the filtration burden to a certain extent, and extending the life of the filtration device.

[0045] In the water purifier raw water tank 1 of this embodiment, the raw water region 16 and the concentrate region 17 are formed as a single-piece tank separated by a partition 18 extending in the front-to-back direction. This structure is simple and easy to implement, and can be formed in one step, for example, by plastic injection molding or metal casting, with injection molding being preferred. When the water purifier raw water tank 1 is a single-piece tank, the cross-section of the tank can be any shape, such as circular, rectangular, square, or other special shapes. The return channel can be positioned on the partition 18 near the raw water rear panel 12 of the tank, and the concentrate inlet 152 can be positioned on the raw water tank bottom panel 15 of the tank, near the raw water front panel 11 of the tank. This ensures that the concentrate inlet 152 is as far from the return channel as possible in the front-to-back direction, thereby achieving optimal return water quality. Furthermore, preferably, the raw water outlet 151 is positioned on the raw water tank bottom panel 15 of the tank, near the raw water front panel 11 of the tank, to maximize the settling distance of water in the raw water region 16 before reaching the raw water outlet 151. Ideally, the concentrated water inlet 152 and the raw water outlet 151 are best set at the edge of the raw water front box 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 can be as close to the raw water front box plate 11 as possible without affecting it.

[0046] In this embodiment, the water tank preferably has an overall rectangular barrel-like structure, with a rectangular cross-section. The tank is enclosed by a raw water front panel 11, a raw water rear panel 12, a raw water left panel 13, a raw water right panel 14, and a raw water tank bottom panel 15 at the bottom. Divider panels 18 are flat plates extending from front to back to the raw water front panel 11 and raw water rear panel 12, respectively. To further consider raw water utilization and recovery rates, the raw water zone 16 formed by the divider panels 18 has a larger volume than the concentrated water zone 17. For example, if the divider panels 18 are located at the 2 / 3 position in the left-right direction, the volume of the raw water zone 16 is set to 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, located on the left and right sides of the water purifier, along the front-to-back direction. The volume ratio of the raw water zone 16 to the concentrated water zone 17 is controlled to control the raw water recovery rate.

[0047] As shown in Figures 10, 14, and 15, the raw water tank 1 of the water purifier in this embodiment includes a filter element 160 with a filter hole 161 covering the raw water outlet 151. The raw water outlet 151 communicates with the interior of the raw water region 16 through the filter hole 161. The filter element 160 filters small impurities such as rust and sand contained in the raw water, thereby improving the pumping efficiency and service life of the booster pump. To achieve this structure, an annular raised boss 190 is provided on the raw water tank bottom plate 15. The raw water outlet 151 is located inside the boss 190. The filter element 160 is cup-shaped, with cylindrical sidewalls 163 and a bottom wall 162. The filter hole 161 is defined in the bottom wall 162. The opening of the filter element 160 engages with the boss 190, allowing raw water to flow through the filter hole 161, allowing the raw water outlet 151 to communicate with the interior of the raw water region 16. In order to ensure connection stability and accuracy, a positioning column 164 can be set on the inner side of the side wall 163 of the filter element 160, and a positioning groove 1901 is opened on the corresponding boss 190. The positioning column 164 can be inserted into the positioning groove 1901. Of course, a positioning groove can also be set on the filter element 160 and a positioning column can be set on the boss 190.

[0048] In order to cooperate with the function of the reflux channel, a liquid level detection component 180 is installed in the raw water area 16 of the raw water tank 1 of the water purifier of this embodiment to detect the raw water level. There are various ways to detect the liquid level detection component 180, for example, a float structure, a sensor structure, etc. There are many existing technologies and they will not be described here. At the same time, the lowest water level detection height of the liquid level detection component 180 is lower than the reflux height of the reflux channel. Through liquid level detection, the liquid level in the raw water area 16 is controlled, especially the lowest water level of the raw water is detected, to avoid the recovery rate being too high and the reflux channel being unable to function. At the same time, the water level is detected during the use of the water purifier to remind timely water replenishment.

[0049] In addition, this embodiment also provides a water purifier that utilizes the aforementioned water purifier 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 filtering device, and a water storage tank base 3. The raw water tank 1 utilizes the aforementioned water purifier raw water tank 1; the water storage tank base 3 is used to support the raw water tank 1 and has a raw water inlet 3112 that cooperates with the raw water outlet 151 and a concentrated water inlet 3113 that cooperates with the concentrated water inlet 152; the filtering device is used to filter and purify the raw water and has a raw water inlet connected to the raw water inlet 3112 and a concentrated water outlet connected to the concentrated water inlet 3113. The water tank seat 3 and the frame of the water purifier are not designed as an integrated whole, but adopt a detachable split design. The raw water tank 1 can be detachably installed in the water purifier through the water tank seat 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 the water tank to be filled with raw water or to pour out concentrated water and other disassembly and cleaning operations.

[0050] As shown in Figure 16, as a further improvement to the water purifier, the water tank base 3 includes a water tank base 31, with a raw water inlet 3112 and a concentrated water inlet 3113 disposed on the water tank base 31. As shown in Figures 12 and 13, the bottom of the raw water tank 1 has a placement slot, with a positioning plate 191 with downward-sloping positioning slopes 192 disposed on the inner sidewalls surrounding the placement slot. The water tank base 31 also has support slopes around its edges that mate with the positioning slopes 192 of the positioning plate 191. The positioning plate 191 at the bottom of the raw water tank 1 mates with the support slopes on the water tank base 31, providing both guidance for placement of the raw water tank 1 and excellent positioning and support once placed, ensuring accurate alignment of the corresponding water outlets. Furthermore, the four side surfaces of the raw water tank 1 continue to extend below the raw water tank bottom plate 15 to form a support plate 19, and a positioning card plate 191 is provided on the inner side surface of the support plate 19, and a plurality of positioning cards 191 can be arranged at intervals around the support plate 19 to facilitate forming a stable support; and, a guiding slope 193 with a larger slope can be provided below the positioning slope 192 on the positioning card plate 191, so as to facilitate the placement of the raw water tank 1 on the water tank seat 3 with a guiding effect and facilitate insertion.

[0051] Preferably, as shown in Figure 16, an integrally formed side stand 32 is provided on the front side of the water tank base 31. A hanging post 3211 with a hanging plug 3212 is provided on the side of the side stand 32 facing the water tank base 31. As shown in Figures 8, 9, and 11, a hanging slot 111 with a slot 113 is provided on the raw water front panel 11 of the raw water tank 1. The hanging post 3211 mates 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 mounting space. The mating of the hanging slot 111 prevents the raw water tank 1 from moving or tipping over on the water tank base 31, ensuring a stable and secure installation. In addition, there is a positioning guide groove 112 in the main body of the hanging slot 111, which is formed by the inward depression of the raw water front box plate 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 column 3211 on the side stand 32, and has a guiding and positioning function.

[0052] Example 3

[0053] As shown in Figures 8, 10, and 17-19, in practice, when the raw water tank 1 needs to be replenished with raw water, the raw water region 16 often has less water than the concentrated water region 17, making it prone to tipping over during carrying. This embodiment further optimizes this problem by providing a tip-over-resistant raw water tank for a drinking water purification device. A handle 20 is connected to the raw water tank 1 for lifting the raw water tank 1, with its ends pivotally connected to the tank body on opposite sides of the raw water tank 1. To achieve the tip-over prevention function, as shown in Figure 10, the two pivot points connecting the handle 20 to the raw water tank 1 are located on either side of a partition 18. The intersection point D between the line connecting the two pivot points and the partition 18 is located near the center of the partition 18. The angle θ formed by the intersection satisfies the following conditions: 45° < θ ≤ 90°. The overflow height of the partition 18 is required to be no less than 1 / 3 of the maximum water storage height of the raw water tank 1. The angle θ can be anywhere between 45° and 90°, such as 46°, 50°, 60°, 70°, 80°, and 90°. From a stability perspective, a larger angle increases stability. Furthermore, the intersection point D can be located in the middle of the partition plate 18, either in the middle or near the middle. The overflow height of the partition plate 18 has certain requirements. If the height is low, even a slight weight bias will not cause the device to tip over. This will only occur after reaching a certain height. Considering the recovery rate of the water purifier 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 raw water tank 1. For example, it can be 1 / 2, 2 / 3, or even the same as the maximum water storage height of the raw water tank 1.

[0054] The anti-rollover raw water tank 1 of the water purifier of this embodiment comprises a raw water area 16 and a concentrated water area 17. The staggered arrangement of the handle 20 and the partition 18 ensures that the handle 20 is positioned in the middle of both the raw water area 16 and the concentrated water area 17. This effectively balances the gravity applied when the raw water tank 1 is lifted, preventing the unbalanced weight from causing the tank to tilt and potentially splashing raw water or concentrated water, or even tipping over. The raw water tank 1 is cylindrical in shape, and its cross-section can be circular, square, rectangular, or other special-shaped. In this embodiment, the raw water tank 1 is a rectangular cylindrical structure, enclosed by a raw water front panel 11, a raw water rear panel 12, a raw water left panel 13, a raw water right panel 14, and a raw water tank bottom panel 15. This makes it easy to manufacture, remove, and place, and it is relatively neatly positioned on the water tank base 3. The partition plate 18 extends in the front-to-back direction to the middle of the front and rear sides of the raw water tank 1. The 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 can be the middle position or close to the middle position. The partition plate 18 can be a flat plate or a non-flat plate structure, such as an arc shape, with a flat plate structure being preferred. With this structure, the partition plate 18 can more easily divide the raw water tank 1, and the handle 20 can be more easily installed in a balanced position, making the raw water tank 1 more portable. Furthermore, the line between the two pivot points is perpendicular to the surface of the partition plate 18, which means that better balance can be achieved.

[0055] To ensure ease of handling and aesthetics of the raw water tank 1, this embodiment further improves the handle 20. As shown in Figures 8, 10, 17, and 18, the handle 20 is pivotally connected to the inside of the raw water tank 1. It forms a U-shaped structure, consisting of connecting arms on the left and right sides, parallel to the left and right side panels of the raw water tank 1, and a central handle arm, parallel to the front and rear side panels of the raw water tank 1. A toggle portion 23 is located in the middle of the handle arm. An open slot 121 is defined on the upper edge of the rear side of the raw water tank 1. Rotating the handle 20 backward allows the toggle portion 23 on the handle 20 to engage with the open slot 121 on the raw water tank 1, securing the handle in place. Alternatively, the open slot 121 could be defined on the upper edge of the front side of the raw water tank 1. In this case, rotating the handle 20 forward allows the toggle portion 23 on the handle 20 to engage with the open slot 121 on the raw water tank 1, securing the handle in place. The handle 20 is housed within the raw water tank 1, remaining relatively unobtrusive and aesthetically pleasing. It also facilitates closing the raw water tank 1 with the cover. To prevent the handle 20 from rotating and falling into the raw water tank 1 and contacting the water, an open slot 121 on the upper edge of the tank body engages with the lever 23 of the handle 20, effectively limiting its position. This also facilitates lifting the raw water tank 1 by levering the handle 20 from the outside, avoiding the unsanitary act of grabbing the handle 20 from inside. As a preferred option, the lever 23 of the handle 20 engages with the open slot 121 on the raw water tank 1, remaining flush with or slightly protruding from the outside, facilitating easy movement of the handle 20.

[0056] Considering the connection reliability and rotation limit of the handle 20 and the raw water tank 1, as shown in Figures 10, 17, 18 and 19, in this embodiment, a pivot seat 30 is set on the raw water left box plate 13 and the raw water right box plate 14 of the raw water tank 1, close to the inner side and the middle of the upper end. It is mainly composed of a support wall 31a with a certain distance from the left and right side plates of the raw water tank 1 and two side connecting walls 32a arranged at relative intervals roughly 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, so that the support wall 31a, the two side connecting walls 32a and the side plate of the raw water tank 1 enclose a accommodating space, and the bottom connecting wall 33 closes the bottom of the accommodating space to form a cylindrical accommodating space with an upper opening. A pivot hole 34 is defined in 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 pivotal connection. Furthermore, an outwardly protruding rotation limiter 22 is provided on the rotating peripheral wall of the pivot shaft 21. Two upwardly protruding stoppers 35 are spaced apart along the front-to-back direction on the bottom connecting wall 33 inside the pivot seat 30, and these stoppers 35 engage with the rotation limiters 22. When the handle 20 rotates to a certain angle in the front-to-back direction, the rotation limiters 22 abut against the stoppers 35, thereby securing the handle 20. To facilitate insertion of the pivot shaft 21 into the pivot hole 34 of the pivot seat 30, a through slot is defined in the peripheral wall of the pivot hole 34 on the support wall 31a, through which the stoppers 35 pass. This through slot not only allows the pivot shaft 21 to be inserted into the pivot hole 34 but also ensures stable pivoting and prevents the pivot shaft 21 from disengaging from the pivot hole 34.

[0057] As shown in Figures 11 and 12, the bottom structure of the raw water tank 1 has been further improved. Support plates 19 extend downward from at least part of the bottom perimeter of the raw water tank 1. These support plates 19 and the bottom perimeter of the raw water tank 1 form a slot that supports and secures the raw water tank 1 to the water tank base 31, enhancing the stability of the raw water tank 1 when mounted on the water tank base 31. Accordingly, as shown in Figure 16, the water tank base 31 is provided with inclined support surfaces at least part of its perimeter. A positioning plate 191 with downwardly sloping positioning surfaces 192 is provided on the inner sidewall of the support plate 19. When the raw water tank 1 is placed on the water tank base 31 of the water tank stand 3, the inclined positioning surfaces 192 of the positioning plate 191 mate with the inclined support surfaces of the water tank base 31. The interaction between the support plates 19 on the raw water tank 1 and the inclined surfaces of the water tank base 31 provides guidance when the raw water tank 1 is placed into the water tank base 31, making it easier to place and more accurately positioned. A guiding slope 193 with a larger slope can be provided below the positioning slope 192 on the positioning card plate 191, so as to facilitate the placement of the raw water tank 1 on the water tank seat 3, thereby providing a guide and making it easier to place the raw water tank 1 thereon.

[0058] This embodiment also provides a water purifier, comprising a main body and a raw water tank 1. The raw water tank 1 utilizes the aforementioned anti-rollover raw water tank 1 for water purifiers. A water tank holder 3 is detachably mounted on the main body. This structure allows the water tank holder 3 to be lifted to balance the raw water tank 1 when replenishing raw water or discharging concentrated water, preventing it from tipping over and potentially splashing raw water or concentrated water or even tipping over. Furthermore, the detachable water tank holder 3 on the main body is modularly integrated with the raw water tank 1, allowing for interchangeability based on specific needs, resulting in increased adaptability.

[0059] Example 4

[0060] This embodiment further provides a water purification tank for a drinking water purifier. This water purification tank is movably mounted on the drinking water purifier and can be removed from the water purifier. This effectively improves the stability of the water purification tank within the drinking water purifier and prevents bacteria from growing inside the water purification tank for a longer period of time. This embodiment uses a household drinking water purifier as an example to illustrate in detail the structure that achieves stable support and light-shielding and antibacterial functions.

[0061] As shown in Figures 20 to 32, this embodiment provides a double-layer, light-proof, and antibacterial water purification tank for a water purifier, comprising a water purification tank 2, an outer shell 2a, and a water storage tank seat 3. Water purification tank 2 is used to store clean water purified by the filter device of the water purifier. It is formed into a box structure with an internal water purification chamber for storing clean water. A water inlet hole 1051 is provided at the bottom of the box, connecting the clean water to the purification chamber. Clean water filtered by the filter device of the water purifier can enter water purification tank 2 through water inlet hole 1051. Water in water purification tank 2 can also be delivered through water inlet hole 1051 to other functional units such as the ice maker for use. The water tank base 3 is used to support the clean water tank 2. The clean water tank 2 is supported and placed on the water tank base 3 in a removable manner. The water tank base 3 is provided with a seat hole 304. The seat hole 304 is configured to cooperate with the water inlet hole 1051 of the clean water tank 2 when the clean water tank 2 is placed on the water tank base 3, so that clean water can enter and exit the clean water tank 2 through the seat hole 304 and the water inlet hole 1051. In this embodiment, the water inlet hole 1051 at the bottom of the clean water tank 2 is surrounded by a downwardly extending protruding ring, which is inserted into the seat hole 304. During use, one-way check valves can be installed in the water inlet hole 1051 of the clean water tank 2 and the seat hole 304 of the water tank seat 3. When the clean water tank 2 is placed on the water tank seat 3, the two one-way check valves are opened to achieve communication. When the clean water tank 2 is removed from the water tank seat 3, the two one-way check valves are closed to achieve closure, thereby meeting the taking and placing operations of the clean water tank 2.

[0062] In this embodiment, a specially designed outer shell 2a is mounted on the water tank seat 3. It is configured so that the clean water tank 2 can be placed into the outer shell 2a through the top of the outer shell 2a. When the clean water tank 2 is placed on the water tank seat 3, its outer sides are surrounded by the outer shell 2a. At least a portion of the outer shell 2a serves as the exposed portion of the water purifier. At least a portion of the outer shell 2a is opaque, and the opaque portion of the outer shell 2a at least includes the exposed portion of the water purifier. At least a portion of the clean water tank 2 is transparent, so that the water level in the clean water tank 2 can be observed through the transparent portion. For example, the outer shell 2a can be completely opaque, or only the exposed portion of the outer shell 2a is opaque, and the clean water tank 2 can be completely transparent or only partially transparent. In this embodiment, the outer shell 2a adopts a completely opaque structure, while the clean water tank 2 adopts a fully transparent structure.

[0063] The double-layer light-proof and antibacterial water purification tank of the water purifier of this solution supports the water purification tank 2 through the water tank seat 3 provided on the body, and the water purification tank 2 is installed in the outer shell 2a, which can stably support and seal the water purification tank 2. The water purification tank 2 is not easy to separate from the body when being transported or accidentally bumped. At the same time, the outer shell 2a part can serve as the body shell and is not light-transmitting, so that light will not shine on the water purification tank 2, which can effectively reduce the growth of bacteria in the water purification tank 2 and keep the water fresh for a long time. In addition, the water purification tank 2 has a transparent part, and the water level can be directly observed, which is convenient for user operation.

[0064] To achieve the opaque effect of outer shell 2a and transparent effect of clean water tank 2, this embodiment configures outer shell 2a to be made of opaque plastic material, while clean water tank 2 is made of transparent plastic material. Plastic material is low-cost, can be quickly injection molded, and has strong shape plasticity. Of course, outer shell 2a can be made of plastic material itself or by attaching an opaque film to its surface.

[0065] As one implementation of the outer shell 2a, the outer shell 2a can be a cylindrical structure with sidewalls, upper and lower openings, and the bottom opening is mounted on the water tank seat 3. As another preferred embodiment, considering the mounting structure of the outer shell 2a on the water tank seat 3, the water tank seat 3 in this embodiment includes an integrated seat plate 301 and upright plate 302. The outer shell 2a, together with the seat plate 301 and upright plate 302 of the water tank seat 3, enclose a space for accommodating the clean water tank 2. The seat plate 301 and upright plate 302 form an L-shaped installation space, which, in conjunction with the outer shell 2a, forms a space with an upper opening to accommodate the clean water tank 2. This meets the installation space requirements for the clean water tank 2 while also simplifying the structure as much as possible to facilitate overall assembly.

[0066] As shown in Figures 22, 24, and 25, the outer shell 2a in this embodiment is primarily composed of a left shell plate 201, a right shell plate 202, and a rear shell plate 203. It is open on both the top and bottom sides and the front side. When the bottom of the outer shell 2a is mounted on the water tank base 3, its bottom opening is sealed by the base plate 301, and its front opening is sealed by the vertical plate 302. This creates a space for the clean water tank 2 to be inserted through the top opening, providing stable support and light protection. Accordingly, the clean water tank 2 primarily comprises a box structure formed by the left clean water box plate 101, the right clean water box plate 102, the front clean water box plate 103, the rear clean water box plate 104, and the clean water tank bottom plate 105. An openable cover 106 is provided at the top opening to facilitate pouring water.

[0067] In order to facilitate the removal and placement of the clean water tank 2 from the outer shell 2a, a handle 107 is pivotally connected to the clean water tank 2 near the top, and a storage groove 206 that can cooperate with the handle 107 is provided at the upper end of the outer shell 2a. The handle 107 is configured so that when the clean water tank 2 is placed on the water tank seat 3 and the handle 107 is rotated and retracted, the handle 107 is located in the storage groove 206 of the outer shell 2a, and does not protrude beyond the side wall of the outer shell 2a or is flush with the side wall. This structural design of the handle 107 is convenient for lifting the clean water tank 2, and the overall design is beautiful and compact, and does not appear abrupt. Here, the handle 107 is set into a U-shaped structure, which is pivotally connected to the outer side of the left and right box plates of the clean water tank 2 to facilitate the lifting operation.

[0068] As shown in Figures 23-31, to ensure the stability of the clean water tank 2 placed on the water tank base 3, in this embodiment, the bottom of the clean water tank 2 is provided with downwardly extending supports 108. The center of the base plate 301 of the water tank base 3 has an upwardly protruding boss, which includes an inner horizontal section 3011 and an inner vertical section 3012. The clean water tank 2 is supported on the base plate 301 of the water tank base 3 via the supports 108. The supports 108 are located outside the boss, and the bottom of the clean water tank 2 is spaced apart from the inner horizontal section 3011 of the boss. This structure ensures that the clean water tank 2 is securely supported on the water tank base 3, while the boss restricts the two-dimensional movement of the clean water tank 2. At the same time, the bottom of the clean water tank 2 does not contact the inner horizontal section 3011 of the boss. This design addresses the difficulty of achieving a fully flat support and also facilitates the installation of corresponding water valves on the clean water tank 2 and the water tank base 3. Preferably, the inner side of the support portion 108 has a limiting portion 109 extending toward the boss direction, and the limiting portion 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, thereby facilitating the installation of the clean water tank 2 into the outer shell 2a and accurately supporting the installation on the water tank seat 3.

[0069] To ensure a stable and secure installation of the outer shell 2a on the water tank base 3, the base plate 301 of the water tank base 3 in this embodiment is provided with multiple plug-in sections 303 with slots A3031. A downwardly extending plug-in plate 205 is provided at the lower portion of the outer shell 2a. The plug-in plate 205 can be inserted into the slots A3031 of the plug-in section 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 of the right and left sides. A step 204 is provided at the lower portion of the outer shell 2a. The step 204 rests on the outer horizontal section 3015, providing secondary positioning of the outer shell 2a and preventing it from moving. In this embodiment, the water tank seat 3's seat plate 301 is provided with an outer horizontal section 3015 only on the right side. The insert plate 205 of the outer shell 2a is horizontally spaced from the right shell plate 202, offset inward. The two are connected by a connecting section, which serves as the step 204. An upwardly projecting rib 3016 is formed on the left edge, or outer edge, of the seat plate 301 of the water tank seat 3. The insert plate 205 of the outer shell 2a is located inward of the rib 3016, facilitating the installation of the outer plate of the water purifier. The inner vertical section 3012 and the outer horizontal section 3015 of the water tank seat 3 are connected in sequence to the bottom horizontal section 3013 and the outer vertical section 3014. The outer horizontal section 3015 is taller than the inner horizontal section 3011, thus forming the aforementioned snap-fit ​​structure.

[0070] In order to enable the clean water tank 2 to be quickly and accurately placed into the outer shell 2a, in this embodiment, guide portions 207 that protrude from the inner side walls are relatively provided on the left and right inner side walls of the outer shell 2a. The guide portions 207 extend from top to bottom and have inclined guide surfaces. The left and right opposite guide surfaces form a guide width for the clean water tank 2 to be placed into the outer shell 2a, and the guide width gradually decreases from top to bottom. The left and right opposite outer side walls of the clean water tank 2 are inclined surfaces that match the guide surfaces of the guide portions 207 on the left and right inner side walls of the outer shell 2a, and the width of the left and right opposite outer side walls gradually decreases from top to bottom. In other words, the opening of the outer shell 2a is larger at the top and smaller at the bottom, and the same is true for the clean water tank 2. Then, the clean water tank 2 can be easily inserted into the opening of the outer shell 2a, and under the guidance of the guide portions 207 of the outer shell 2a, the clean water tank 2 can be quickly and accurately placed into place.

[0071] As a preferred solution, the widths of the left and right opposite outer walls of the water purification tank 2 are set to fit into the storage box inside the refrigerator door. For example, the maximum width of the water purification tank 2 can be set to 10 cm, 9 cm, 8 cm, 7 cm, 5 cm, 4 cm, etc. When in use, the user can conveniently remove the water purification tank 2 from the water purifier, place it in the storage compartment on the side of the refrigerator door for cooling, and then put it back into the water purifier to quickly drink cold water.

[0072] Furthermore, as shown in Figure 33, this embodiment also provides a water purifier, comprising a frame and the aforementioned double-layer light-proof and antibacterial water purifier tank. The water tank seat 3 is removably mounted to the frame using a snap or screw mechanism, with the left and right sides of the outer shell 2a exposed as the outer walls of the water purifier. This water purifier tank structure offers an aesthetically pleasing overall appearance, provides excellent tank support stability, and protects the water tank 2 from direct sunlight, ensuring long-term freshness of the water.

[0073] Example 5

[0074] This embodiment also provides a water purifier storage device. This device utilizes a modular design and can be integrally mounted on the body of the purifier. Furthermore, the device is designed as a split assembly, adaptable to various specifications and models, offering high versatility. As shown in Figures 16 and 34-38 , the water purifier storage device primarily consists of a raw water tank 1, a clean water tank 2, and a water tank base 3. Both the raw water tank 1 and the clean water tank 2 are supported and placed on the water tank base 3 in a removable manner.

[0075] In this embodiment, the water tank stand 3 primarily 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 a plastic material, such as ABS plastic, obtained through integral injection molding. The water tank stand 3 manufactured using this material exhibits excellent overall performance, low cost, high production efficiency, and light weight. The water tank base 31 can be plate-shaped, typically not a flat plate, but rather a plate with concave and convex shapes with defined mounting locations. It is positioned horizontally and can support the raw water tank 1 and the clean water tank 2. The side stand 32 can also be plate-shaped and positioned vertically in front of the water tank base 31. The raw water tank 1 and the clean water tank 2 are placed side by side on the water tank base 31 of the water tank stand 3, with their front sides leaning against the side stand 32 of the water tank stand 3, and the sides of the adjacent tanks being close together. Close means that the side panels of the two tanks can be abutted against each other, or a small distance can be provided. The side stand 32 and the raw water tank 1 can be detachably connected via a hook fastener. The hook fastener is configured to limit the position movement of the raw water tank 1 in directions other than the upward lifting direction when the raw water tank 1 is placed on the water tank base 31 of the water tank seat 3.

[0076] The water storage device of the water purifier of this embodiment adopts a modular structural design, in which the raw water tank 1 and the clean water tank 2 are installed side by side on the water tank seat 3 in a detachable manner, and the water tank seat 3 itself is also an integrated detachable structure. The three together constitute a water storage module, which can be installed on the water purifier as a whole. This is not only conducive to the full utilization of the body space, but also the water storage module can be adapted for use according to different models, and is relatively versatile. In addition, the water tank seat 3 isolates the raw water tank 1 and the clean water tank 2 from other parts of the water purifier, forming an effective water area isolation, reducing the impact of water on other components.

[0077] As shown in Figures 37 to 38, a structural form of a raw water tank 1, a clean water tank 2 and a water tank seat 3 is provided in an embodiment. The raw water tank 1 and the clean water tank 2 can both be a roughly rectangular barrel-shaped box structure as a whole. Considering the optimization of the water volume carried by the raw water tank 1 and the clean water tank 2, the width of the raw water tank 1 in the left and right directions is greater than the width of the clean water tank 2, and the length of the clean water tank 2 in the front-to-back direction is greater than its width in the left and right directions. As shown in Figures 16 and 35 , considering the different volumes occupied by the raw water tank 1 and the purified water tank 2, and to fully utilize the space within 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 sides, while the corresponding side stand 32 is divided into a raw water stand 321 and a purified water stand 322. The raw water base 311 includes a raw water tank base 3111 for supporting and mounting the raw water tank 1, while the purified water base 312 includes a purified water tank base 3121 for supporting and mounting the purified water tank 2. The raw water tank base 3111 is higher than the purified water tank base 3121. Furthermore, the rear side of the raw water tank 1 is flush with the rear side of the purified water tank 2, occupying a rectangular area on the water purifier, resulting in a compact layout, high space utilization, and an aesthetically pleasing overall appearance.

[0078] The water purification base 312 includes a guard plate 3221, a side connecting plate 3222, and a side wing plate 3223. The side connecting plate 3222 extends left and right, while the guard plate 3221 extends front to back, with its front side extending to the left side of the raw water stand 321 and its rear side connected to one side of the guard plate 3221. The side wing plate 3223 extends front to back, with its rear side connected to the other side of the guard plate 3221. The side connecting plate 3222 serves as a partition between the raw water tank 1 and the purified water tank 2. The side of the raw water tank 1 can be supported on the side connecting plate 3222 for greater stability. The guard plate 3221 can be adapted to fit the shape of the front side of the purified water tank 2, for example, with the middle portion recessed forward to form a spout. The side wing plates 3223 provide reinforcement and serve as a base for connecting other components, such as the side panels of the water purifier. A connector 3114 is provided at the bottom of the water tank base 31 of the water tank seat 3 for removably attaching the water tank seat 3 to the water purifier frame. For example, one or more connectors 3114 may be provided on the left and right sides and the rear side. The connector 3114 may be a downwardly protruding plate, for example, having a circular hole and a slot therein. The circular hole can be screwed into a stud hole on the water purifier frame, or the slot can be snap-fitted into a protrusion on the frame. Other connection methods are also possible. One or more connectors 3213 are provided on the side stand 32 of the water tank seat 3, for example, along the right side of the raw water stand 321, in the vertical direction. These connectors connect to other components of the water purifier body. For example, the connector 3114 may be connected in the same manner as the connector 3114, or may employ a slot structure, a protrusion structure, a stud structure, or the like.

[0079] As shown in Figures 16 and 35 , as a preferred connection method between the raw water tank 1 and the raw water stand 321, a hanging post 3211 with a hanging plug 3212 is provided on the side of the raw water stand 321 near the water tank base 31. A hanging slot 111 with a slot 113 is provided on the raw water tank 1. The hanging post 3211 and the hanging slot 111 form a hanging fastener; the hanging post 3211 cooperates with the hanging slot 111, and the hanging plug 3212 can be inserted into the slot 113. The main body of the hanging slot 111 on the front side of the raw water tank 1 is a rearwardly recessed positioning guide 112. The positioning guide 112 cooperates with the hanging post 3211 to provide positioning guidance, and the slot 113 is located at the upper end of the positioning guide 112. The raw water tank 1 and the raw water stand 321 cooperate with the hanging plug column 3211 and the hanging slot 111 to form a hanging fastener. The raw water tank 1 will not move or overturn on the water tank base 31, and the installation is stable and reliable.

[0080] 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 snaps into place around the raw water tank base 3111. The base 3111 also has guiding slopes around it, which mate with the slots on the bottom of the raw water tank 1 for positioning. The bottom of the clean water tank 2 also has a slot that snaps into place around the clean water tank base 3121. The clean water tank base 3121 also has guiding slopes around it, which mate with the slots on the bottom of the clean water tank 2 for positioning. The inclined surfaces of the tank body and the base provide a guide when the water tank is placed into the water storage tank base 31, making insertion easier and positioning more accurate.

[0081] In addition, as shown in Figure 38, this embodiment also provides a water purifier, comprising a frame and a raw water tank 1. The raw water tank 1 utilizes the modular, split-type raw water tank 1 described above for the water purifier. The frame has a mounting space for a water tank holder 3. The raw water tank 1 is removably mounted within the mounting space on the frame via connectors 3114 on the water tank holder 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. The raw water tank 1 in this water purifier can be centrally installed, which not only fully utilizes the space within the machine, but also allows the water storage module to be adapted for different models, resulting in relatively high versatility.

[0082] Example 6

[0083] This embodiment also provides a water purifier, which optimizes the layout structure of the water path components and circuit components inside the body, makes full use of the body space as much as possible, and improves the working safety and versatility of the water purifier. The water purifier shown in Figures 39 to 44 includes a frame 9 and a power adapter 95 installed in the frame 9, a circuit board assembly 94 and a water path board assembly 96, wherein the power adapter 95 is used to power the water purifier, the circuit board assembly 94 is used for circuit control of the water purifier, and is electrically connected to the power adapter 95, and the water path board assembly 96 is used to install the filter element and perform water path distribution for the water purifier. The circuit board assembly 94 generally includes components such as a water path board, a water control valve, a pump, a filter element, etc., which are used in combination according to different functional requirements. They belong to the prior art and will not be described here.

[0084] In this embodiment, the circuit board assembly 94, the power adapter 95, and the waterway plate assembly 96 are all centrally mounted on one side of the frame 9, for example, on the left front side of the water purifier, and are arranged vertically from top to bottom. Correspondingly, the circuit board mounting position 92, the adapter compartment 91, and the waterway plate compartment 93 are sequentially arranged on the left front side of the frame 9 from top to bottom, and the circuit board assembly 94, the power adapter 95, and the waterway plate assembly 96 are respectively mounted in corresponding positions. At the same time, the circuit board mounting position 92 is configured to allow the circuit board assembly 94 to be removably mounted on the circuit board mounting position 92, the adapter compartment 91 is configured to allow the power adapter 95 to be removably mounted in the adapter compartment 91 from top to bottom in the longitudinal direction, and the waterway plate compartment 93 is configured to allow the waterway plate assembly 96 to be removably mounted in the waterway plate compartment 93 in a transverse direction. The so-called transverse direction refers to the thickness direction of the waterway plate assembly 96 being along the up-down direction, and the front-back and left-right directions being in the horizontal direction.

[0085] The water purifier of this embodiment installs the circuit board assembly 94, the power adapter 95 and the water channel plate assembly 96 on one side of the water purifier frame 9, which has a high degree of centralized installation, a relatively reasonable space occupation, and is also convenient for improving the versatility of various models. At the same time, the circuit components and the water channel components are arranged in the upper and lower directions to achieve better separation of water and electricity, and the equipment operation safety is relatively high.

[0086] To further improve work safety, the adapter compartment 91 and the waterway plate compartment 93 are separated by an isolation plate 97, which is relatively isolated in space and has a relatively complete separation of water and electricity. The adapter compartment 91 and the waterway plate compartment 93 are open toward the outside of the water purifier, allowing the power adapter 95 and the waterway plate assembly 96 to be installed in the adapter compartment 91 and the waterway plate compartment 93, respectively. Of course, the adapter compartment 91 and the waterway plate compartment 93 can also be open or closed in other directions according to specific functional requirements, but they must be open toward the outside of the water purifier. In addition, the open sides of the adapter compartment 91 and the waterway plate compartment 93 can be closed by installing the water purifier side panels. By removing and installing the side panels, the overall aesthetics of the water purifier can be achieved and the inspection and maintenance of the power adapter 95 and the waterway plate assembly 96 can be facilitated. As a further improvement, a leak hole is opened at the bottom of the waterway plate compartment 93. The leak hole can be opened on the bottom plate of the water purifier to facilitate timely detection of leaks in the waterway plate assembly 96.

[0087] In order to improve the installation reliability of the power adapter 95 in the adapter compartment 91, a support plate A911a is provided in the adapter compartment 91, which has a support plane, and the power adapter 95 is supported on the support plane of the support plate A911a in the adapter compartment 91. In this structure, the power adapter 95 is supported on the support plate A911a in a plane, the support surface is large, the installation is firm, and the stability is high. At the same time, in conjunction with the support of the power adapter 95 by the support plate A911a, connecting columns 912a are provided on the upper and lower sides of the support plate A911a in the adapter compartment 91, and the power adapter 95 is installed and fixed by the connecting columns 912a. For example, the connecting column 912a can be a stud, and a pressure ring is fixed to the stud by a screw. The pressure ring can compress the wires at both ends of the power adapter 95, or other installation methods such as a snap-on structure can be used.

[0088] Considering further the preferred installation method for circuit board assembly 94, circuit board mounting position 92 is a bracket extending from frame 9. Circuit board assembly 94 is mounted on the bracket using fasteners such as screws and clips. The brackets can be one or more, with two brackets being selected in the accompanying drawings. In one embodiment, circuit board assembly 94 includes a circuit board, a box body 941, and a box cover 942. Box body 941 is fixed to the bracket, and the circuit board is placed within box body 941 and sealed by box cover 942. Preferably, the circuit board is a PCB and is mounted within box body 941 using glue potting to improve the safety and shock resistance of the circuit board.

[0089] To facilitate connecting the power adapter 95 to an external power source, a wire trough 931 extends from the waterway compartment 93. The power cord of the power adapter 95 with a plug can be installed along the wire trough 931 and extend outside the water purifier. As one implementation of the wire trough 931, the wire trough 931 is provided on the bottom plate of the water purifier and is formed by a pair of vertical plates extending upward from the bottom plate at a predetermined distance.

[0090] Example 7

[0091] As shown in Figures 45 to 54, this embodiment further provides a water distribution system for a water purifier, including: a filter element waterway plate 900, the filter element waterway plate 900 is used to install a filter element module 903, a flow channel for water circulation is provided in the filter element waterway plate 900, and an interface for connecting raw water and an outlet for filtered clean water to flow out are provided on the filter element waterway plate 900. The raw water enters the filter element module 903 through the interface for filtration and then flows out through the outlet; it also includes a water distribution transfer valve group 800, which is connected to the filter element waterway plate 900; specifically, a main flow channel 819 and at least one secondary flow channel are provided in the valve group body of the water distribution transfer valve group 800, and the main flow channel 81 9 is provided with two ports, namely the clean water inlet 803 and the clean water outlet 804. The clean water inlet 803 is connected to the filter element waterway plate 900 through a pipe, and is used to receive the clean water filtered by the filter element module 903, and connect the clean water to the main channel 819; the clean water outlet 804 is used to connect to the clean water tank of the clean drinking equipment, and connect the clean water in the main channel 819 to the clean water tank of the clean drinking equipment; the main channel 819 and the secondary channel are connected through a water pump, the water inlet of the water pump is connected to the main channel 819, and the water outlet of the water pump is connected to the secondary channel. The water pump is used to pump the clean water in the main channel 819 into the secondary channel, and a water outlet is provided on the secondary channel for connecting the clean water to the corresponding functional module of the clean drinking equipment.

[0092] In this embodiment, the water distribution transfer valve assembly 800 does not have an installation position for installing the filter element module 903, but is provided with an independent filter element waterway plate 900 for installing the filter element module 903. The filter element waterway plate 900 is provided with a filter element water purification port 911 and a filter element water inlet 912, which are respectively used to connect with the corresponding interfaces of the filter element module 903, that is, the filter element water inlet 912 is used to connect with the water inlet of the filter element module 903, and the filter element water purification port 911 is used to connect with the purified water outlet of the filter element module 903. In conjunction with Figures 48 and 49, specifically:

[0093] A raw water flow channel 919 is provided in the filter element waterway plate 900 to connect to the filter element water inlet 912, so as to allow the raw water to enter the filter element module 903; more precisely, a motor water outlet 907 is also provided on the filter element waterway plate 900, and the motor water outlet 907 is used to be connected 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 water outlet 907, and finally enters the filter element module 903; a water quality detector 906 is also provided on the raw water flow channel 919 for detecting the water quality before filtration.

[0094] A clean water flow channel 921 is provided in the filter element waterway plate 900 and is connected to the filter element clean water outlet 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 the 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 provided in the clean water outlet flow channel, and the clean water outlet flow channel is connected to the clean water flow channel 921 through the one-way valve 905.

[0095] Corresponding to different choices of filter element module 903 in practice, when the filter element module 903 adopts an RO filter element, a filter element wastewater port 910 is also provided in the filter element waterway plate 900, and the filter element wastewater port 910 is used to be connected to the wastewater interface of the filter element module 903; a wastewater flow channel 920 is correspondingly provided in the filter element waterway plate 900 to connect to the filter element wastewater port 910, and the wastewater flow channel 920 is connected to a wastewater valve 904, and the wastewater valve 904 is used to discharge wastewater through a wastewater outlet 916; similarly, the inlet of the wastewater valve 904 is connected to the wastewater flow channel 920, and the outlet of the wastewater valve 904 is connected to the wastewater outlet flow channel, and the wastewater outlet 916 is provided in the wastewater outlet flow channel, and the wastewater outlet flow channel is connected to the wastewater flow channel 920 through the wastewater valve 904, and the wastewater is discharged using the wastewater outlet 916.

[0096] This embodiment utilizes a filter cartridge waterway plate 900 for directly mounting a filter cartridge module 903, and only requires the necessary mounting components. This allows the filter cartridge waterway plate 900, when mounted with the filter cartridge module 903, to form the most basic, functionally independent, integrated filter module for the drinking water purification device, demonstrating strong versatility and adaptability. The water distribution transfer valve assembly 800, acting solely as the rear-stage purified water distribution valve assembly, receives purified water filtered by the filter cartridge module 903 through the purified water inlet 803. The purified water is then distributed to the purified water tank and corresponding functional modules using the purified water outlet 804 and the distribution of the secondary flow channels, achieving multi-directional transfer and distribution of purified water. Through this design, the filter element waterway plate 900 and the water distribution transfer valve group 800 have simple structures, fewer pipelines, and the corresponding overall volume of the drinking water purification equipment is small. In addition, different water distribution transfer valve groups 800 can be directly replaced according to the different functions of the drinking water purification equipment. For example, when the drinking water purification equipment only needs to supply hot water or cold water separately, the water distribution transfer valve group 800 can be provided with only a single secondary flow channel, and the purified water is sent to the corresponding heating module or cooling module through a single water pump. When it is necessary to provide hot water and cold water functions at the same time, the water distribution transfer valve group 800 can be provided with a double flow channel, and different water pumps are used to send the purified water to the heating module and cooling module respectively. According to the change of function, different valve group bodies can be replaced accordingly without changing the filter element waterway plate 900, so as to realize the universal application of the filter element waterway plate 900 under different functions, thereby effectively reducing production costs and facilitating the disassembly and assembly of components.

[0097] In this embodiment, to achieve comprehensive functionality of the drinking water purification device, two secondary flow channels are provided within the valve assembly body, namely a primary flow channel 820 and a secondary flow channel 821. As shown in Figures 51-54 , the primary flow channel 820 and the primary flow channel 819 are connected via a first water pump 805. The first water pump inlet 814 is connected to the primary flow channel 819, and the first water pump outlet 813 is connected to the primary flow channel 820. The first water pump 805 is used to pump the purified water in the primary flow channel 819 into the primary flow channel 820. The primary flow channel 820 is provided with a first outlet 809. Correspondingly, the secondary flow channel 821 and the primary flow channel 819 are connected via a second water pump 806. The second water pump inlet 816 is connected to the primary flow channel 819, and the second water pump outlet 815 is connected to the secondary flow channel 821. The second water pump 806 is used to pump the purified water in the primary flow channel 819 into the secondary flow channel 821. The secondary flow channel 821 is provided with a second outlet 812. Specifically, the drinking water purification device in this embodiment has the drinking functions of normal temperature water, hot water and cold water, wherein normal temperature water and hot water share a water inlet, and a heating body is provided in the water inlet pipeline as a heating module, which is used to heat and prepare hot water when needed, and discharge normal temperature water when the heating body is not running; the drinking water purification device is also provided with a refrigeration module for preparing cold water, and the above-mentioned first outlet 809 is used to connect to the refrigeration module to provide clean water to the refrigeration module; the second outlet 812 is used to connect to the pipeline where the heating body is located, and is used to provide clean water to the heating module.

[0098] In this embodiment, the valve block body is a plate-like structure, specifically composed of a combined water distribution plate 1 801 and a water distribution plate 2 802. A main flow channel 819 and at least one secondary flow channel are formed internally. The clean water inlet 803 and the clean water outlet 804 are located at the same end of the valve block body. As shown in FIG51 , the valve block body is a rectangular plate-like structure, with the clean water inlet 803 and the clean water outlet 804 located at the same end in the longitudinal direction and arranged side by side along the width of the valve block body at this end. This makes the valve block body more compact and space-saving, and makes it easier to connect pipes within the drinking water purification device. Preferably, the clean water inlet 803 and the clean water outlet 804 are arranged on the same water distribution plate, such as on the water distribution plate 1 801. Preferably, in order to further enhance the layout advantages of each component, the second outlet 812 is also provided on a water distribution plate, and a matching groove for installing the second outlet 812 is provided on the water distribution plate, so that at least part of the second outlet 812 is embedded in the water distribution plate. As shown in Figure 52, the second outlet 812 is distributed on the second water distribution plate 802, and a matching groove for installing the second outlet 812 is provided on the second water distribution plate 802, so that at least part 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 group body.

[0099] Drinking water purification equipment in the industry often uses RO reverse osmosis membrane filter elements as the core filter material. When the water purification equipment is in shutdown or standby state, there are both concentrated water and clean water in the RO reverse osmosis membrane filter element. The total dissolved solids (TDS) concentration of the concentrated water is much higher than that of the clean water, which will cause the ions in the concentrated water to diffuse into the clean water. As a result, the TDS concentration of the first cup of water is relatively high when the water purification equipment is turned on to dispense clean water next time. This problem has become a pain point for drinking water purification equipment.

[0100] In order to solve the problem of high TDS concentration in the first cup of water mentioned above, this embodiment is further provided with a fresh water function component for flushing the filter element on the valve group body. Specifically, a fresh water inlet channel 822 and a fresh water outlet channel 823 are further provided in the valve group body. The fresh water inlet channel 822 and the fresh water outlet channel 823 are connected through a third water pump 807. The third water pump inlet 818 is connected to the fresh water inlet channel 822, and the third water pump outlet 817 is connected to the fresh water outlet channel 823. A fresh water inlet 811 is provided on the fresh water inlet channel 822. The live water inlet 811 is used to connect and receive the clean water in the water purification tank of the drinking water purification equipment; a fresh water outlet 810 is provided on the fresh water outlet channel 823, and the fresh water outlet 810 is used to connect the clean water to the filter element module 903 of the drinking water purification equipment, so that the remaining clean water in the clean water tank can be sent to the filter element module 903 through the third water pump 807. After the filter element module 903 stops preparing clean water, the surface of the filter element is rinsed and finally discharged to the raw water tank of the drinking water purification equipment through the waste water outlet of the filter element, thereby effectively improving the problem of too high TDS of the first cup of water and improving the water quality of the first cup of water.

[0101] As a different embodiment, the fresh water outlet 810 can also connect the purified water directly to the raw water tank of the drinking water purification device. In this case, the residual purified water in the purified water tank can be directly discharged to the raw water tank to achieve purified water replacement. When the purified water has remained 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 to the raw water tank, which not only saves water but also keeps the purified water in the purified water 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 fresh water function of the purified water tank and the flushing effect of the filter element.

[0102] To achieve a compact and reasonable layout, the multiple water pumps on the valve group body in this embodiment are all distributed on the same side of the valve group body, and as shown in Figure 52, in conjunction with the long plate structure of the valve group body, the multiple water pumps are preferably arranged along the length of the valve group body, making the spatial arrangement more compact. More optimally, the multiple water pumps on the valve group body are arranged on the same water distribution board as the clean water inlet end 803 and the clean water outlet end 804, such as on the water distribution board 801, so as to achieve the centralized installation of most components on the same water distribution board. As shown in Figure 51, 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 board 801 and arranged along the length of the valve group body.

[0103] In order to detect the water quality of the purified water after filtration in a timely manner, in this embodiment, a water quality detector 808 can be set at the front section of the main channel 819 to detect the water quality of the purified water entering the main channel 819.

[0104] This embodiment also provides a drinking water purification device that utilizes the multifunctional modular water distribution system described above. The filter cartridge module 903 is mounted on the filter cartridge waterway plate 900, and the clean water outlet 915 on the filter cartridge waterway plate 900 is connected to the clean water inlet 803 on the water distribution adapter valve assembly 800 via a pipeline. The clean water outlet 804 on the water distribution adapter valve assembly 800 is connected to the clean water tank via a pipeline. Through the coordinated cooperation of the filter cartridge waterway plate 900 and the water distribution adapter valve assembly 800, multi-directional clean water distribution can be achieved. Different water distribution adapter valve assemblies 800 can be replaced accordingly according to the changes in the function of the drinking water purification device without having to change the filter cartridge waterway plate 900, thereby achieving universal application of the filter cartridge waterway plate 900 for different functions, thereby reducing production costs.

[0105] As a specific preferred installation method, combined with Figure 45, the filter element module 903 in the drinking water purification equipment is placed vertically and fixed on the filter element waterway plate 900, and the filter element waterway plate 900 is placed horizontally accordingly; the water distribution adapter valve group 800 is vertically installed in the drinking water purification equipment and is connected with the filter element waterway plate 900. As shown in Figure 45, it is the installation state inside the drinking water purification equipment. The filter element waterway plate 900 and the water distribution adapter valve group 800 are distributed on different planes and are vertically distributed, which is more convenient to arrange according to the internal space layout of the equipment, to achieve a more compact installation, and further contribute to the miniaturization of the entire equipment; at the same time, the water distribution adapter valve group 800 is arranged vertically, and the pump bodies of each water pump thereon extend in the horizontal direction. The inlet and outlet of each water pump on the valve group body are distributed up and down, and the water pump outlets are all located below the water pump inlet, which is conducive to fully combining the water flow gravity factor to ensure water flow stability and ensure the stable operation of each pump body.

[0106] Example 8

[0107] As shown in Figures 55 and 56, this embodiment further provides a convenient gas cylinder mounting assembly for a water purifier, comprising a mounting frame and an aeration module. The mounting frame is used to mount and support the aeration module, which is used to inject gas into drinking water to produce sparkling water. The aeration module comprises a gas cylinder 601 and an aeration adapter 602. The mounting frame has a gas cylinder mounting space, within which the gas cylinder 601 is mounted. The aeration adapter 602 is provided with a mounting screw for connecting to the gas cylinder 601. Once the gas cylinder 601 is installed in the mounting space, the mounting screw can be used to achieve a detachable connection with the aeration adapter 602 and connect the gas circuit. Specifically, the mounting screw adopts a threaded screw, and the bottle mouth of the gas cylinder 601 is provided with a corresponding mounting thread. The aeration adapter 602 is also provided with a switch to control the on / off of the gas circuit.

[0108] As a different design of the gas injection adapter 602, one of its implementation plans is that the gas injection port of the gas injection adapter 602 is connected to the water faucet pipeline of the water purifier. The water faucet pipeline is a pipeline 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 pipeline 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 water outlet pipeline through the gas injection adapter 602, so that sparkling water can be directly prepared inside the water purifier for users to drink. The external structure design of the water purifier can be further simplified and beautiful.

[0109] Another embodiment of the gas injection adapter 602 is shown in FIG55 . The gas injection adapter 602 is provided with a gas injection transfer channel 603, which is also connected to the gas cylinder 601. The end of the gas injection transfer channel 603 is provided with a water cup connector 604. The water cup connector 604 is provided with an interface for detachably mounting a bubble water cup 605. The interface has a gas injection port for injecting gas into the bubble water cup 605. Specifically, the interface on the water cup connector 604 can also be in the form of a threaded screw-on interface. The bubble water cup 605 has a corresponding mounting thread. When the bubble water cup 605 containing cold water is mounted on the water cup connector 604, gas injection can be started to produce bubble water. This method separates the bubble water injection and cold water collection operations. The user can use cold water separately and choose whether to prepare bubble water.

[0110] It should be noted that in this embodiment, the bottom of the gas cylinder 601 mounted on the gas injection adapter 602 has an elastic support component, which has an elastic avoidance distance. The elastic support component is configured so that when the gas cylinder 601 is installed in 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 pre-pressure between the bottle mouth of the gas cylinder 601 and the installation screw. In practice, due to the miniaturization design requirements of water purifier equipment, the installation space for gas cylinders is very limited. Traditional installation methods often require holding the bottle body with both hands and pushing it in the direction of the installation screw, while simultaneously rotating the bottle body with both hands to slowly install it. With the above-mentioned elastic support component design of this embodiment, when the gas cylinder 601 enters the installation space, the bottom of the gas cylinder will contact and press down the elastic support component, causing the elastic support component to generate a thrust corresponding to the direction of the installation screw, that is, the direction of the axis extension of the gas cylinder 601, thereby alleviating the influence of the gas cylinder 601's own gravity, greatly reducing the pressure on the person holding and rotating the bottle body, and even when the thrust is sufficient, the bottle body can be rotated with one hand, effectively reducing labor intensity, improving installation efficiency, and achieving labor-saving and convenient installation. To achieve a better labor-saving effect, preferably, as shown in Figure 55, the gas cylinder 601 can be set to a vertical installation state, and the installation screw on the gas injection adapter 602 corresponds to a vertically extending threaded screw. The thrust of the elastic support component is vertically upward. The vertical installation method is not only conducive to giving full play to the thrust effect of the elastic support component, but also more convenient for aligning the installation position, and is also conducive to ensuring the safety of the gas in the gas cylinder 601 during long-term use.

[0111] In practice, in order 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 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; when the gas cylinder 601 is installed in place, the elastic support component still has elastic restoring force, thereby fully overcoming the pressure of the self-weight of the gas cylinder 601 and realizing labor-saving installation.

[0112] As an optional embodiment of the elastic support component, as shown in Figure 56, the elastic support component includes a cylindrical gas cylinder support seat 606 and an elastic member 610 installed inside the gas cylinder support seat 606. The top of the elastic member 610 is used to support the gas cylinder 601. During the installation of the gas cylinder 601, the top surface of the elastic member 610 never exceeds the gas cylinder support seat 606, and the top surface of the elastic member 610 can directly contact and support the bottom of the gas cylinder 601. Furthermore, a gas cylinder support plate 607 can be installed on the top of the elastic member 610. The gas cylinder support plate 607 is used to contact and support the bottom surface of the gas cylinder 601, thereby increasing the support contact area and supporting stability. To ensure the directional stability of the elastic thrust, the gas cylinder support plate 607 is further optimized to be provided with a guide member that cooperates with the gas cylinder support seat 606. The guide member is used to limit the gas cylinder support plate 607 to move only along the axis of the gas cylinder 601 within the gas cylinder support seat 606. Specifically as shown in Figure 55, at least one group of outwardly protruding guide rails 608 can be set on the side of the gas cylinder support seat 606, and a guide groove is provided in the guide rail 608. The side of the gas cylinder support plate 607 is correspondingly provided with at least one group of guide blocks 609 that cooperate with the guide groove. The guide blocks 609 are embedded in the guide groove inside the guide rail 608. The guide blocks 609 and the guide rails 608 both extend along the axial direction of the gas cylinder 601, thereby achieving precise guidance of the thrust direction and preventing directional deviation.

[0113] In practice, the elastic member 610 can adopt a variety of elastic structures, such as the most common columnar spring, etc. More preferably, the conical coil spring adopted in this embodiment as shown in Figure 56, and the bottom fixed end of the conical coil spring is the end with a smaller cross-section, and the top supporting end is the end with a larger cross-section, maintaining a support range with a larger thrust force, enhancing the support stability, and the conical coil spring in a compressed state has a smaller overall height due to the conical design than an ordinary columnar spring, and is more suitable for situations where the installation space of the gas cylinder is small and limited, meeting the requirements of miniaturization of the entire drinking water purification equipment.

[0114] This embodiment also provides a water purifier, which includes the aforementioned gas cylinder mounting assembly. The mounting frame for the pumping module is located within the water purifier. A sidewall cover is provided on the outside of the gas cylinder mounting space to enclose the space. The sidewall cover is detachably connected to the gas cylinder mounting frame, such as by a snap-fit ​​mounting arrangement. Specifically, the gas cylinder mounting assembly is located on one side of the water purifier in the left and right width directions, and the sidewall cover on the outside of the gas cylinder mounting space serves as part of the exterior panel of the water purifier. When gas cylinder 601 needs to be replaced, the sidewall cover can be simply opened, providing a very convenient operation.

[0115] In conjunction with the foregoing embodiments, in this embodiment of the water purifier, the filter cartridge module 903 is preferably positioned in the central region of the water purifier. The gas cylinder mounting assembly is located on one side of the water purifier in the left-right width direction, and the water cup connector 604 in the gas cylinder mounting assembly extends toward the front of the water purifier. The gas cylinder mounting opening faces one edge of the left-right width direction of the water purifier. This allows gas cylinder 601 to be installed from the side of the width direction, providing ample external operating space and facilitating the removal and placement of gas cylinder 601. Furthermore, the rear side of the filter cartridge module 903 is provided with a raw water tank 1 and a clean water tank 2, arranged side by side along the width direction. The gas cylinder 601 and the raw water tank 1 are located on the same side of the width direction, preferably on the right side. In this embodiment, the raw water tank 1 can be directly removed for adding or emptying water. As a component that needs to be removed and placed frequently, positioning the gas cylinder 601 and the raw water tank 1 on the right side is more in line with user operating habits and facilitates force application.

[0116] Example 9

[0117] In combination with Figures 59-64, this embodiment further provides a power motor mounting structure for a drinking water purification device, including a power mounting frame 401, wherein the power mounting frame 401 has a motor mounting space, and a partition substrate 402 is provided on the upper side of the motor mounting space, and the filter element power pump 400 is detachably mounted below the partition substrate 402 through a connecting frame 403; the lower side of the motor mounting space has an opening, and the filter element power pump 400 can be placed into the motor mounting space through the lower opening; and at least one opening is provided on the frame around the motor mounting space as an inspection window; the position on the power mounting frame 401 corresponding to the connecting pipe end of the filter element power pump 400 has a pipe opening connected to the water supply pipe, and the connecting pipe end is used to connect the filter element module 903 and raw water of the drinking water purification device respectively.

[0118] It should be noted that the filter power pump 400 is an essential component of the RO reverse osmosis filter element water purification equipment. The traditional installation method in the industry is to install the bottom of the filter power pump 400 directly on the base of the water purification equipment. After the other components in the water purification equipment are installed, the base of the water purification equipment is finally installed, and then the performance of the equipment is tested. On the one hand, this method will cause the vibration generated during the operation of the filter power pump 400 to be transmitted to other internal components through the base, causing resonance, resulting in loud noise and poor stability of the whole machine; on the other hand, the performance of the equipment can only be tested after the base of the whole machine is installed. Once the filter power pump 400 has a problem and needs to be replaced, the base of the equipment must be completely removed before the filter power pump 400 can be removed, which makes the operation cumbersome and time-consuming.

[0119] In this embodiment, the filter element power pump 400 is completely separated from the outer shell and base of the drinking water purification device. By setting an independent motor installation space on the internal power mounting frame, the filter element power pump 400 is installed upside down from bottom to top on the partition base plate 402. While facilitating direct placement and installation, the filter element power pump 400 is separated from other functional components inside the drinking water purification device. After the entire machine is finally installed, the filter element power pump 400 is separated from the surrounding outer shell and base of the drinking water purification device within the installation space to maintain a certain gap, thereby greatly reducing the resonance effect of the filter element power pump 400 during operation and achieving smooth and noise-reduced operation of the drinking water purification device. In addition, at least one open window for maintenance is provided on the frame around the filter element power pump 400. As shown in Figure 59, open windows are provided at the front and rear end positions and the left side of the filter element power pump 400 for maintenance; after the filter element power pump 400 and other functional components are installed, there is no need to install the entire machine casing and base, and the filter element power pump 400 can be directly tested for performance from the open window position, and the filter element power pump 400 and the partition substrate 402 are detachably installed. Once the filter element power pump 400 is found to be malfunctioning, the filter element power pump 400 can be taken out for repair or replacement in time, which is convenient to operate. After checking that all functional components are operating normally, the entire machine casing and base can be installed, avoiding the tedious casing disassembly process, saving time and effort.

[0120] To further reduce the vibration impact of the filter element power pump 400, an optimized solution is that the connecting frame 403 includes an annular fitting portion 404 that is mounted in contact with the wall surface of the filter element power pump 400. Flat mounting portions 406 extend from the two side edges of the annular fitting portion 404. The flat mounting portions 406 are used to cooperate with the partition base plate 402 for installation, thereby fixing the filter element power pump 400 below the partition base plate 402. The use of the annular fitting portion 404 to fit the wall surface of the filter element power pump 400 is conducive to enhancing the installation and fixation of the connecting frame 403 and the filter element power pump 400. Specifically, various common fixing methods such as welding, riveting, and bolting can be used; the flat mounting portion 406 is used for flat mounting with the partition base plate 402 to maintain flat contact and enhance connection stability.

[0121] As a more optimized embodiment of the connecting frame 403, as shown in conjunction with Figures 63 and 64, in this embodiment, the connecting frame 403 includes an annular fitting portion 404 that is mounted in contact with the wall surface of the filter element power pump 400. Extended transition portions 405 are symmetrically provided on both sides of the annular fitting portion 404. The outer ends of the extended transition portions 405 on both sides are respectively provided with flat mounting portions 406. The annular fitting portion 404, the extended transition portions 405, and the flat mounting portions 406 are all smoothly connected. The extended transition portions 405 gradually extend upward and outward away from the annular fitting portion 404, so that the height of the flat mounting portion 406 is not less than the height of the top surface of the annular fitting portion 404. The flat mounting portion 406 is used to mate with the partition base 402. As shown in conjunction with Figure 62, 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 base 402, but also maintains a certain gap between the top of the filter element power pump 400 and the partition base 402 to avoid large-area contact, thereby reducing the impact of resonance.

[0122] In practice, based on various different designs of the connecting frame 403, the design that can further weaken the resonance transmission is that a shock-absorbing gasket 407 is provided between the planar mounting portion 406 and the partition substrate 402. The shock-absorbing gasket 407 can be made of various common materials such as rubber and nylon, which can further weaken the vibration impact of the filter element power pump 400, so that there is a certain gap between the planar mounting portion 406 and the partition substrate 402, thereby enhancing the installation stability and further reducing the installation contact area.

[0123] As one of the practically optional implementations, the planar mounting portion 406 may be provided with multiple mounting points spaced along the length of the filter element power pump 400, allowing for detachable connection to the partition base plate 402. This multiple point connection ensures a secure connection while also helping to reduce the contact area between the connecting frame 403 and the partition base plate 402, thereby further reducing the impact of vibration transmission from the filter element power pump 400. Each mounting point is provided with a shock-absorbing gasket 407 for vibration reduction. Specifically, the planar mounting portion 406 and the partition base plate 402 can be fastened together using bolts. Since the filter-cartridge power pump 400 is mounted upside down, bolts can be passed through the planar mounting portion 406 and the partition base plate 402 from bottom to top for fastening. Specifically, a gasket mounting hole can be provided on the planar mounting portion 406. A shock-absorbing gasket 407 is positioned within the gasket mounting hole and extends beyond the upper and lower surfaces of the planar mounting portion 406. A bolt connection hole for the bolt to pass through is provided in the center of the shock-absorbing gasket 407. Using the shock-absorbing gasket 407 enhances the vibration reduction effect and also helps to improve the fastening of the bolts.

[0124] This embodiment further provides a drinking water purification device having the power motor mounting structure as described above, wherein the water inlet of the filter element power pump 400 is connected to the raw water of the drinking water purification device, specifically, it can be connected to the raw water tank 1 in the above embodiment, and the water outlet of the filter element power pump 400 is connected to the filter element module 903 of the drinking water purification device; furthermore, the bottom support leg of the power mounting frame 401 is detachably mounted to the base of the drinking water purification device, and there is a certain height gap between the bottom of the filter element power pump 400 and the base of the drinking water purification device. As analyzed above, such a design allows the filter element power pump 400 to be separated from the entire machine housing and base, and the entire machine housing and base can be installed after the performance test of the filter element power pump 400 is completed, thereby avoiding repeated disassembly and assembly of the housing and base; and the bottom of the filter element power pump 400 remains suspended in the air to avoid vibration transmission through the entire machine base to generate resonance, thereby ensuring that other components are not affected by the vibration of the filter element power pump 400, and achieving long-term stable operation of the entire machine.

[0125] The water purification device of this embodiment also provides cold water. A refrigeration module 8 is internally installed. Specifically, a refrigeration mounting frame 110 is provided on one side of the power mounting frame 401. This refrigeration mounting frame 110 has a mounting space for the refrigeration module. Specifically, an opening is provided at the top of the refrigeration mounting frame 110 for accessing and placing the refrigeration module 8. A partition is provided between the mounting space for the filter power pump 400 and the mounting space for the refrigeration module. This not only improves the structural strength of the frame but also further separates the filter power pump 400 from the refrigeration module 8, effectively preventing collision damage between the filter power pump 400 and the refrigeration module 8 during transportation. It also prevents motor vibration from affecting the operation of the refrigeration module 8.

[0126] To achieve a reasonable distribution of the various component modules within the water purification device, the power mounting frame 401 in this embodiment is divided into two upper and lower mounting spaces by a partition base 402. The upper mounting space is equipped with at least one pump body smaller in volume than the filter cartridge power pump 400. Depending on the richness of the functions within the water purification device, multiple pump bodies are often required. The filter cartridge power pump 400, which provides power for raw water filtration, is particularly powerful, heavy, and large. 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 helps to enhance the stability of the structural distribution and achieves a centralized distribution of multiple pump body components on the mounting frame. Specifically, in practice, a water distribution transfer valve group 800 is installed in the upper mounting space. The water distribution transfer valve group 800 is used to distribute the purified water after being filtered by the filter cartridge module. The water distribution transfer valve group 800 is equipped with at least one power pump group for distributing the filtered purified water to the corresponding functional module. The volume and power of each power pump group are smaller than the filter cartridge power pump 400 below. The structure of the water distribution transfer valve assembly 800 is as described in the above embodiment, wherein the three power pumps are arranged in sequence along the length 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 entire machine, but also separates the distribution of different water channels, making the internal pipelines clearer and easier to inspect and maintain.

[0127] Example 10

[0128] In conjunction with Figures 59-61 , this embodiment further elaborates on the structure of the power mounting bracket 401. An edge plate 4012 extending in the front-to-back direction is provided on the outer side of the partition base plate 402. The top surface of the edge plate 4012 is lower than the top surface of the partition base plate 402, thereby forming a recessed step on the outer side of the partition base plate 402. This recessed step is used to accommodate a clean water delivery pipeline in the clean water channel distribution valve assembly, so that the distribution of this pipeline does not affect the installation and distribution of other components on the partition base plate 402. Specifically, the clean water channel distribution valve assembly includes a transfer valve assembly body 800, on which is mounted at least one water channel transfer pump. As shown in Figure 60 , the transfer valve assembly body 800 adopts the structure described in the above embodiment. In this embodiment, a water outlet pipe connected to a water tap pipe provided with a heating body is placed on the recessed step formed on the outer side of the partition substrate 402, that is, a water outlet pipe connected to the second outlet 812 as described in the above embodiment is placed. Furthermore, a snap-fit ​​frame 4013 is provided on the outer step surface of the partition substrate 402. The snap-fit ​​frame 4013 is located above the edge plate 4012 and is used to snap-fit ​​and limit the surface of the water outlet pipe installed on the edge plate 4012. The snap-fit ​​frame 4013 is preferably provided with an arc-shaped structure opening downward to achieve a tight fit with the pipe surface.

[0129] To 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 of the partition base plate 402 is provided on the right edge opposite the edge plate 4012. Multiple upwardly extending support plates 4014 are spaced apart on the support plate seat 4016. As shown in Figures 59 and 60, one end of each waterway transfer pump extends into the space between adjacent support plates 4014. Furthermore, the partition base plate 402 is provided with support ribs 4017, which are parallel to the support plate seat 4016 and disposed between the support plate seat 4016 and the edge plate 4012. Each waterway transfer pump is located above the support ribs 4017, and arc-shaped slots corresponding to the outer wall of the pump body can be provided on the support ribs 4017 to provide stable support for the pump body.

[0130] This embodiment also provides a water purification device having a power mounting frame 401 as described above, wherein a filter cartridge power pump 400 is mounted in the lower mounting space of the power mounting frame 401 and detachably secured to a partition base plate 402 via a connecting plate. The transfer valve assembly body 800 is mounted in the upper mounting space of the power mounting frame 401. This arrangement not only facilitates a rational distribution of internal space and promotes miniaturization of the entire device, but also separates the different water channels, making internal piping more clearly visible and easier to inspect and maintain.

[0131] In practice, the top of the power mounting frame 401 is closed by a water tank seat 3, and the water tank seat 3 and the power mounting frame 401 are detachably connected. The raw water tank 1 and the clean water tank 2 are distributed on the water tank seat 3. The raw water tank 1 and the clean water tank 2 are both detachably connected to the water tank seat 3 below, so that the water tanks can be taken out and placed at any time. The use of the water tank seat 3 also realizes the separation of the water tank and the lower pump body pipeline.

[0132] The drinking water purification equipment also includes a complete machine base 5 and an external shell. The bottom of the power mounting frame 401 is detachably connected to the complete machine base 5. Specifically, the four corners of the bottom of the power mounting frame 401 respectively have support feet 4011, and the support feet 4011 are used to be detachably connected to the complete machine base 5, and the side of the power mounting frame 401 is detachably connected to the circumferential external shell, thereby realizing the above-mentioned ability to comprehensively test the pump body performance after the filter element power pump 400 is installed and before the complete machine base 5 and the external shell are installed, avoiding repeated disassembly and assembly of the complete machine base 5 and the shell, and simplifying installation and maintenance operations.

[0134] As shown in Figures 57-59 , this embodiment further provides a refrigeration mounting frame 110 for the beverage purifier. The refrigeration mounting frame 110 has an internal mounting space for accommodating the refrigeration module 8, and an opening is provided at the top of the refrigeration mounting frame 110 for inserting and removing the refrigeration module 8. A connecting member is provided at the bottom of the refrigeration mounting frame 110, located within the mounting space, for supporting and removably connecting the refrigeration module 8. A connecting support 1107 is also provided at the bottom of the refrigeration mounting frame 110 for removably connecting to the base 5 of the beverage purifier. Connectors are provided around the perimeter of the refrigeration mounting frame 110 for removably connecting to the exterior panel of the beverage purifier. An opening is provided on a side wall of the refrigeration mounting frame 110 for accommodating an exhaust mounting frame 1101. The opening for accommodating the exhaust mounting frame 1101 is preferably provided on the rear wall of the refrigeration mounting frame 110, but in practice, the exhaust mounting frame 1101 may be provided on other sides as needed. The connection components of the bottom of the refrigeration mounting frame 110 connected to the refrigeration module 8 can be specifically in various forms. For example, multiple groups of fixing columns 1103 can be set around the bottom of the refrigeration mounting frame 110, and the fixing columns 1103 are located in the installation space. A card slot is provided on the top of the fixing columns 1103, and a connecting hole is provided in the card slot. In practice, mounting columns that match the card slots on the tops of the fixing columns 1103 are respectively provided around the bottom of the refrigeration module 8, so that the bottom of the refrigeration module 8 is embedded in the fixing columns 1103 and accurately positioned. Then, fastening bolts can be used to pass through the connecting holes from the bottom of the fixing columns 1103 upward and fasten them to the mounting columns at the bottom of the refrigeration module 8, so as to realize detachable installation and limit the refrigeration module 8 to prevent displacement; alternatively, a snap-in structure can be provided on the fixing columns 1103 to realize a snap-in connection with the bottom of the refrigeration module 8; or a snap-in structure can be directly provided around the bottom of the refrigeration mounting frame 110 for detachable installation of the refrigeration module 8. Furthermore, to enhance structural stability, reinforcing ribs 1106 can be connected between two adjacent sets of fixing columns 1103. For example, in this embodiment, reinforcing ribs 1106 are connected between two sets of fixing columns 1103 located on the same side in the left-right direction. Similarly, connecting brackets 1107 can also be fastened to the entire base 5 using bolts. Multiple bolt fastening locations can be provided at the top and bottom of the refrigeration mounting frame 110 for mounting to the exterior panel. Alternatively, a snap-fit ​​structure can be used for removable connection.

[0135] In this embodiment, the top of the refrigeration mounting frame 110 is set to be open for the refrigeration module 8 to move in and out, and the refrigeration module 8 is fixed with the bottom connecting parts, which is convenient for the installation and placement of the refrigeration module 8, and a special refrigeration mounting frame 110 is used to place the refrigeration module 8. The refrigeration mounting frame 110 is detachably connected to the base and appearance panel of the drinking water purification equipment. The installation and maintenance of the refrigeration module 8 can be completed before the base and appearance panel are installed, and the base and appearance panel can be installed finally. Compared with the traditional method of installing the refrigeration module 8 on the base of the equipment, it can avoid the situation of repeatedly disassembling and assembling the base when problems arise during maintenance, and facilitates the rapid installation and maintenance of the equipment.

[0136] It is very important to provide sufficient ventilation and heat dissipation for the refrigeration module 8. Therefore, an exhaust fan is often installed in the water purifier device for exhaust and heat dissipation. In this embodiment, the exhaust fixing bracket 1101 for mounting exhaust devices is preferably installed on the rear wall of the refrigeration mounting bracket 110. To improve the position stability of the exhaust fixing bracket 1101, the upper parts of the two sides of the rear wall of the refrigeration mounting bracket 110 are further provided with support planes 1105 for supporting the exhaust fixing bracket 1101. Between the two sides of the rear wall is a space for the exhaust fixing bracket 1101 to extend downward. In practice, the rear side of the refrigeration module 8 is equipped with heat dissipation fins, and the exhaust fixing bracket 1101 is fixedly mounted on the heat dissipation fins. Exhaust devices such as fans are also installed on the bracket. The upper part of the exhaust fixing bracket 1101 is correspondingly provided with a contact plane that matches the support plane 1105 to achieve stable support on the support plane 1105 and maintain installation stability. Furthermore, reinforcing ribs are connected between the bottoms of the two sides of the rear wall of the refrigeration mounting rack 110 to enhance the structural stability of the mounting rack.

[0137] The refrigeration mounting frame 110 in this embodiment is located in the lower rear area of ​​the main body of the beverage purifier. Specifically, a filter element module 903 is provided in the middle of the beverage purifier. The upper rear portion of the filter element module 903 is provided with a clean water tank 2 and a raw water tank 1 in sequence along the left and right width directions. The lower rear portion of the filter element module 903 is the refrigeration mounting frame 110 and the power mounting frame 401 for mounting the power pump structure. To achieve safe separation between the refrigeration module 8 and other functional modules, a front partition 1102 is further provided on the front side wall of the refrigeration mounting frame 110. A partition A4015 is provided on the side wall of the refrigeration mounting frame 110 in the left and right directions that does not face the exterior panel. Both the front partition 1102 and the partition A4015 are used to separate the refrigeration tank installation space from the other installation spaces of the beverage purifier. The front partition 1102 is also provided with an avoidance groove for pipeline connection.

[0138] In order to improve the stability and lightweight of the frame structure, it can be optimized that multiple layers of ribs are provided on the four sides of the frame along the length extension direction of the refrigeration installation frame 110. The multiple layers of ribs are spaced apart to form a grid-like structure. This structure can effectively reduce the weight of the frame while ensuring the strength and stability of the frame structure.

[0139] This embodiment also provides a beverage purification device, comprising the refrigeration mounting frame 110 as described above, and also comprising a complete machine base 5, wherein the complete machine base 5 has a ventilation seat 1104, and the ventilation seat 1104 has an air inlet hole that communicates with the outside world; the complete machine base 5 is detachably connected to the bottom of the refrigeration mounting frame 110, specifically through a connecting support 1107 provided at the bottom of the refrigeration mounting frame 110, and can be fastened by bolts or snaps. Correspondingly, an exhaust fixing frame 1101 is supported on the rear wall of the refrigeration mounting frame 110, and an exhaust device, such as a fan, is provided in the exhaust fixing frame 1101; and a certain height gap is provided between the bottom of the exhaust fixing frame 1101 and the complete machine base 5, so that the exhaust device is located at the upper part of the rear wall of the refrigeration mounting frame 110. The drinking water purification equipment also includes an appearance panel, which is detachably connected to the refrigeration mounting frame 110, and the appearance panels connected to the side walls of the refrigeration mounting frame 110 are provided with exhaust channels communicating with the internal space. For example, the appearance panels installed on the outer wall and rear wall of the refrigeration mounting frame 110 can both be in the form of grid plates. In addition to the exhaust device on the rear wall of the refrigeration mounting frame 110 for exhaust, the outer walls of the left and right directions of the refrigeration mounting frame 110 adopt an open design, which is directly connected to the outside world through the exhaust channel on the appearance panel, further promoting sufficient heat dissipation.

[0140] This embodiment uses a bottom-intake airflow and an upper exhaust system at the rear, which fully ensures heat dissipation and meets product application scenarios without affecting other settings. Furthermore, a ventilation seat 1104 protrudes upward within the base 5, creating a ventilation gap 1109 of a certain height between the bottom surface of the ventilation seat 1104 and the bottom surface of the rest of the base 5, ensuring sufficient air intake and heat dissipation.

[0141] In this embodiment, the top opening of the refrigeration mounting frame 110 is sealed by a water tank seat 3. The refrigeration mounting frame 110 and the water tank seat 3 are detachably connected, and the raw water tank 1 and purified water tank 2 are detachably mounted on the water tank seat 3. Specifically, the refrigeration module 8 and the raw water tank 1 can be positioned on the same side in the left-right direction, with the raw water tank 1 positioned above the refrigeration module 8. The water tank seat 3 securely separates the refrigeration module 8 from the water tank, promoting safe separation of water and electricity.

[0142] Example 12

[0143] In combination with Figures 65 to 71, this embodiment further provides a water collection box for a drinking water device. As shown in Figure 1, the water collection box 700 is located below the water faucet 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 is provided with a water collection cavity for collecting accumulated water. The cover plate 720 is used to cover the water collection box body 710, and the cover plate 720 is provided with a leakage hole communicating with the water collection cavity; wherein the cover plate 720 and the water collection box body 710 are detachably connected, and a water receiving area 721 and a pressing area 722 are respectively provided on the cover plate 720 along the front and rear directions. The rear direction is the direction in which the water collection box 700 and the drinking water device body are installed in coordination. The leakage hole is provided in the water receiving area 721 for collecting water dripping from the water inlet of the drinking water device, and the pressing area 722 is used for a person to press and remove the cover plate 720.

[0144] As shown in Figure 66, a front support portion 715 and a rear support portion 714 are respectively provided in the front and rear directions inside the water collection box body 710 for stably supporting the cover plate 720, wherein the rear support portion 714 and the cover plate 720 are movably fitted together; through the above design, the cover plate 720 is configured so that when the pressing area 722 is pressed downward, the cover plate 720 can rotate around the rear support portion 714, so that one end of the water receiving area 721 of the cover plate 720 rotates upward and separates from the water collection box body 710. When it is necessary to clean the accumulated water, the lever principle can be used to directly press the pressing area 722 to rotate the cover 720 around the support point of the rear support part 714. After one end of the water receiving area 721 is tilted upward, the cover 720 can be directly removed from the tilted end to clean the internal accumulated water. During the removal of the cover 720, there is no need for human hands to be inserted into the accumulated water. Compared with the traditional design that requires manual labor to pull out the cover, the user experience is effectively improved, and the cleaning timing is not affected by the temperature of the accumulated water. The entire operation process is simple and convenient.

[0145] As one embodiment of the movable cooperation between the rear support portion 714 and the cover plate 720, as shown in Figure 66, the cover plate 720 is provided with a mounting portion 723; a snap-fitting groove 724 is defined within the mounting portion 723, corresponding to and cooperating with the rear support portion 714 of the water collection box body 710. The snap-fitting groove 724 is located forward of the pressing area 722. When the pressing area 722 is pressed, the cover plate 720 rotates and tilts by the movable cooperation between the snap-fitting groove 724 and the rear support portion 714. More preferably, the snap-fitting groove 724 is configured as a V-shaped groove with an opening gradually increasing from top to bottom and an open bottom. The top end of the rear support portion 714 is embedded in the V-shaped groove, and the snap-fitting groove 724 is capable of rotating about the rear support portion 714. The cooperation between the snap-fitting groove 724 and the rear support portion 714 ensures both the position limiting and stable support of the cover plate 720 and the rotational flexibility of the cover plate 720. In practice, the mounting portion 723 can be a portion extending beyond the thickness of the cover plate 720 itself, as shown in Figure 66, which is a portion protruding downward from the thickness of the cover plate 720, or a snap-fit ​​groove 724 can be opened in the cover plate 720 itself, so that the part of the cover plate 720 area where the snap-fit ​​groove 724 is located becomes the mounting portion 723.

[0146] When the locking cam 723 is in the unlock state, the locking cam 723 is in the unlock state, and the winch 708 is locked.

[0147] Secondly, as one of the multiple implementation options available in practice, the cover plate 720 and the rear support portion 714 can also be rotated by adopting a hole-axis matching direction. For example, a bottom through-hole structure is opened on the cover plate 720, and the rear support portion 714 is set as an axis-shaped structure passing through the through-hole. The hole-axis structure is used to support the cover plate 720, and at the same time, the cover plate 720 can be pressed and rotated around the rear support portion 714.

[0148] 67 to 69 , in this embodiment, the extension height of the rear end box wall 712 of the water accumulation box body 710 is lower than the extension height of the rear support portion 714. When the cover plate 720 is placed on the water accumulation box body 710, there is a certain gap between the top of the rear end box wall 712 and the bottom surface of the pressing area 722, so that the pressing area 722 can be pressed downward, causing one end of the water receiving area 721 of the cover plate 720 to rotate upward and separate from the water accumulation box body 710.

[0149] As different embodiments of the rear support portion 714, the rear support portion 714 can be installed on the bottom wall of the water accumulation box body 710, or installed on the four sides of the water accumulation box body 710, such as being connected to at least one side wall of the water accumulation box body 710; or it can be connected to both the bottom wall and the side wall of the water accumulation box body 710, and extend in the left and right width direction of the water accumulation box body 710. The extended width of the rear support portion 714 is equal to or less than the width of the water accumulation cavity in the water accumulation box body 710. The width direction referred to here refers to the left and right direction perpendicular to the front-to-back direction in the figure. In practice, the rear support portion 714 can adopt an integrated structure or a multi-section structure. Its width can extend to connect to both sides of the water accumulation box body 710, or it can be less than the width of the water accumulation cavity. Its connection end with the water accumulation box body 710 can be connected to at least one side of the box wall or to the bottom wall, so as to achieve stable support and flexible cooperation for the cover plate 720. As shown in Figure 66, the rear support part 714 has two ends extending and connected to the box walls on both sides, and the bottom is connected to the bottom wall of the water accumulation box body 710, and has a one-piece plate structure with the same width as the water accumulation chamber; the rear support part 714 can also be set as an axis-like structure connected to the side wall of the water accumulation box body 710, and rotatably cooperated with the corresponding through hole opened on the cover plate 720.

[0150] In this embodiment, the front support portion 715 within the water accumulation box body 710 is used to cooperate 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 accumulation box body 710, or installed on the surrounding box walls of the water accumulation box body 710, such as being connected to at least one side wall of the water accumulation box body 710; or being connected to both the bottom wall and the side wall of the water accumulation box body 710. The extension width of the front support portion 715 is equal to or less than the width of the water accumulation cavity within the water accumulation box body 710. The front support portion 715 can be a one-piece structure or a multi-section structure, as long as it can provide a stable support point for the front side of the cover plate 720. As shown in Figure 67, outwardly protruding support points or support columns can be provided on the inner walls of both sides of the water accumulation box body 710 to serve as the front support portion 715. As a different implementation option, a portion of the box wall around the water accumulation box body 710 can be directly used as the front support part 715 to support the cover plate 720, such as setting at least a portion of the front box wall of the water accumulation box body 710 as the front support part 715, placing the front end of the cover plate 720 on the front box wall of the water accumulation box body 710, or opening a support groove in a partial area on the front box wall of the water accumulation box body 710 so that the front end of the cover plate 720 is at least partially embedded in the support groove.

[0151] To further enhance the support stability of the cover plate 720, it can be further optimized to further provide an auxiliary support member 716 within the water accumulation box body 710, which is used to cooperate with the rear support portion 714 and the front support portion 715 to provide multi-point stable support for the cover plate 720. In this embodiment, the auxiliary support member 716 can be arranged in the area between the rear support portion 714 and the front support portion 715. Similar to the design of the rear support portion 714, the auxiliary support member 716 can also adopt a one-piece or multi-stage design. Its installation position and extension width are not further described. Preferably, to facilitate cleaning of the interior of the water accumulation chamber, the front support portion 715 and the auxiliary support member 716 both adopt a support point or support column structure protruding outward from the inner side of the water accumulation box body 710.

[0152] In practice, optionally, feet 711 are 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.

[0153] This embodiment further provides a drinking water device, which utilizes 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 connection portion 713 on the water collection box. The water collection box is mounted on the drinking water device body via the connection portion 713. As one of the different implementations, the water collection box body 710 can be configured to be detachably connected to the drinking water device body. In this case, a connecting buckle can be provided on the rear end box wall 712 or the side box walls of the water collection box body 710 as the connection portion 713, so that the water collection box body 710 can be directly removed to dump the accumulated water. As another implementation, the water collection box body 710 can be configured to be fixedly connected to the drinking water device body. For example, if the water collection box body 710 and the base of the drinking water device body are integrated, in this case, the planar area where the water collection box is connected to the drinking water device body serves as the connection portion 713, and the connection portion 713 can also serve as the rear end box wall 712 of the water collection box body 710. The above design can meet various water cleaning methods. The water box can be removed as a whole and the cover 720 can be removed for cleaning, or the water box can be kept installed and only the cover 720 can be removed for cleaning. The operation is convenient, and direct contact with the accumulated water is avoided during the removal of the cover 720, thereby improving the user experience.

[0154] Example 13

[0155] As shown in FIG72 , this embodiment further provides a water pipe distribution system for a water purifier, comprising a raw water tank 1, a filter cartridge module 903, and a clean water tank 2. The raw water tank 1 is connected to the filter cartridge module 903 via a raw water pipe 105b, and the filter cartridge module 903 is connected to the clean water tank 2 via a clean water pipe 204b. In practice, a one-way valve may be provided on the clean water pipe 204b. It should be noted that in this embodiment, a water inlet is provided at the bottom of the clean water tank 2, serving as both a clean water inlet for receiving filtered clean water and a clean water outlet for supplying water to the distribution pipe 304b. Furthermore, the distribution pipe 304b is provided with a water tank interface, a clean water interface, and an external interface. The distribution pipe 304b is connected to the clean water tank 2 via the water tank interface, and is connected to the clean water pipe 204b via the clean water interface. The distribution pipe 304b distributes clean water through the corresponding external interface. The clean water tank 2 of this embodiment can adopt the clean water tank structure of the above embodiment, and the bottom of the clean water tank 2 can also be detachably mounted on the water storage tank seat. The water storage tank seat is provided with a water outlet corresponding to the water outlet at the bottom of the clean water tank 2, and both the water storage tank seat and the clean water tank 2 are provided with a water stop valve. When the clean water tank 2 is configured on the water storage tank seat, the water stop valves are opened to supply water; when the clean water tank is separated from the water storage tank seat 3, the water stop valve is closed to prevent water from flowing.

[0156] Depending on the design of the different functions of the water purifier, in practice, different external interfaces can be set on the distribution pipeline 304b to distribute purified water to different functional modules. For example, when only the cooling water function is provided, the distribution pipeline 304b is provided with a corresponding external interface connected to the cooling module 8; when only the normal temperature water and hot water functions are provided, the distribution pipeline 304b is provided with an external interface connected to the water outlet branch 305b, which is connected to the water faucet and is provided with a heater. The normal temperature water outlet and the hot water outlet on the water faucet share a water outlet. When normal temperature water is required, the heater does not heat the purified water, and the water faucet directly discharges normal temperature water; when hot water is required, the heater is activated to heat the purified water.

[0157] To achieve comprehensive functionality for the drinking water purification device in this embodiment, the external interface on the distribution line 304b includes both a connection to the refrigeration module 8 and a connection to the water outlet branch 305b. The water outlet branch 305b is connected to the water tap and is equipped with a heater. The distribution line 304b is connected to the refrigeration module 8 and is equipped with a second self-priming pump. The water outlet branch 305b is equipped with a first self-priming pump. The outlet of the heater is connected to a water vapor separator via a pipeline, which is equipped with an exhaust port and a water outlet. The inlet and outlet ends of the heater are each equipped with a temperature sensor. The outlet serves as both a normal temperature water outlet and a hot water outlet. When the heater is heated, hot water flows out of the outlet; when the heater is not heated, normal temperature water flows out of the outlet. The outlet of the refrigeration module 8 is connected to the cold water outlet via the cold water line 402b, which uses a separate outlet for cold water. In practice, each water outlet is arranged in a water tap.

[0158] In this embodiment, through the coordinated design of multiple interfaces on the distribution pipeline 304b, the filtered clean water is not directly connected to the clean water tank 2, but is first connected to the distribution pipeline 304b, and then connected to the clean water tank 2 through the water tank interface on the distribution pipeline 304b. When the clean water tank 2 is configured on the water storage tank seat, the clean water can be circulated to the clean water tank 2 for storage, or directly circulated to the heating body or refrigeration module 8; and when the clean water tank 2 is removed, the filtered clean water and the distribution pipeline 304b are still connected, and the water stop valve in the water tank seat is closed to prevent the water from overflowing. Instead, the clean water is directly circulated to the heating body or refrigeration module 8 via the corresponding interface on the distribution pipeline 304b, so that the drinking water purification equipment can still realize the normal water collection and drinking function after the clean water tank 2 is removed, which greatly improves the convenience of use of the equipment.

[0159] A more optimized design is that the filter element module in this embodiment specifically utilizes an RO reverse osmosis filter element. A corresponding booster pump is installed on raw water pipeline 105b, which is used to pump raw water from raw water tank 1 into filter element module 903. The wastewater outlet of filter element module 903 is connected to raw water tank 1 via wastewater pipeline 203b, which is equipped with a wastewater valve. The water system in this embodiment uses the booster pump to provide more efficient power for raw water filtration. Combined with the design of the back-end self-priming pumps 1 and 2, this system can achieve a constant speed and flow rate of water output from the drinking water purifier by controlling the pump operation program. This facilitates more precise temperature control and improves the control accuracy of the water outlet temperature and single-time water output volume.

[0160] In order to further improve the utilization rate of water resources, a more optimized implementation plan is, as described in the above embodiment, an overflow partition is provided in the raw water tank 1, which divides the inner cavity of the raw water tank 1 into a concentrated water area and a raw water area; the bottom of the raw water area is connected to the filter element module through the raw water pipe 105b; the outlet of the wastewater pipe 203b is connected to the bottom of the concentrated water area, that is, the initial raw water is stored in the raw water tank 1 for supplying water to the filter element module 903 for filtration, and the wastewater generated after filtration by the filter element module 903 flows back to the concentrated water area through the wastewater pipe 203b, and an overflow port is provided on the top of the overflow partition. When the returned wastewater reaches a certain height, it overflows into the raw water area through the overflow port for repeated filtration and utilization, thereby effectively improving the utilization rate of the raw water.

[0161] To test the quality of both raw and filtered water, a more optimal design in practice is to install water quality detectors on both the raw water pipeline 105b and the distribution pipeline 304b. To further purify the water during use, UV sterilizers are installed on the cold water pipeline 402b and the outlet branch pipe 305b, respectively, to achieve overflow disinfection and purification of the water flow, thereby improving water quality. To facilitate timely monitoring of the water level in the water tanks, a more optimized design is to install water level sensors in both the raw water tank 1 and the clean water tank 2. This allows the raw water tank 1 to prompt the user to add raw water when the water level drops to a certain level. The clean water tank 2 is then equipped with a water level sensor that monitors the water level at both the extreme high and extreme low water levels. This allows the user to add water to continue purification when the water level is low, and to discontinue filtration and purification and supply water to the clean water tank 2 when the water level reaches the high level, to prevent the clean water from overflowing the tank.

[0162] In combination with the above-mentioned embodiments, in order to avoid a relatively high TDS concentration in the first cup of water, the water system of this embodiment further proposes a solution. A flushing interface is also provided on the distribution pipe 304b. The flushing interface is connected to the water inlet of the filter element module 903 and is used to receive the clean water in the clean water tank 2 into the filter element module 903 for flushing. When the filter element module 903 needs to be flushed, the remaining clean water in the clean water tank 2 is discharged into the filter element module 903 through the flushing interface. After the filter element module 903 stops preparing clean water, the clean water directly flushes the surface of the filter element and finally flows back to the concentrated water area of ​​the raw water tank 1 through the wastewater pipe 203b, thereby effectively improving the problem of excessively high TDS in the first cup of water and improving the water quality of the first cup of water.

[0163] To ensure the freshness of the water in the clean water tank 2, as a more preferred embodiment, a replacement interface can be provided on the distribution pipeline 304b. The replacement interface is connected to the raw water tank 1 and is used to receive the clean water in the clean water tank 2 into the raw water tank 1. Specifically, it is connected to the raw water area of ​​the raw water tank 1. In this way, the remaining clean water in the clean water tank 2 can be directly discharged into the raw water area of ​​the raw water tank 1 to achieve clean water replacement. If the clean water in the clean water tank 2 has remained in the clean water tank for a long time and the user does not want to drink it directly, this method can be used to directly replace the clean water back into the raw water tank 1, which not only saves water but also maintains the freshness of the clean water in the clean water tank 2. In practice, it is also possible to simultaneously provide a flushing interface and the above-mentioned replacement interface on the distribution pipeline 304b, thereby achieving the freshness function of the clean water tank 2 and also achieving a flushing effect on the filter element, improving water quality.

[0164] This embodiment further provides a drinking water purification device, including a frame and a water system, wherein the water system adopts the design of the above-mentioned water system, and the raw water tank 1, the filter element module and the clean water tank 2 are all installed on the frame, which not only satisfies the multi-directional independent water supply of filtered clean water to the clean water tank 2, the refrigeration module 8 and the heating body, but also realizes the constant connectivity of the water path. It can still be used normally even after the clean water tank 2 is removed, and the control of multiple groups of pump bodies is conducive to further improving the accuracy of the quantitative and constant temperature of the water output, which has significant advantages in use, provides users with a better use experience, and improves the convenience of use.

[0165] As a further optimization of the drinking water purification equipment, the clean water tank 2 is arranged above the refrigeration module 8, and the bottom height of the clean water tank 2 is higher than the top height of the refrigeration module 8. Therefore, combined with the self-weight inertia of the water flow, when the clean water tank 2 is configured, the clean water in the tank can always supply water to the refrigeration module 8, ensuring that the refrigeration module 8 will not be empty-sucked. Even when the clean water tank 2 is removed, the clean water in the clean water pipeline 204b can still enter the distribution pipeline 304b through the clean water interface and directly supply water to the refrigeration module 8, which can also avoid the empty suction phenomenon of the refrigeration module 8 and ensure the long-term stable operation of the equipment.

[0166] The above is a schematic description of the present invention and its embodiments. This description is not restrictive and is only one embodiment of the present invention. Therefore, if a person skilled in the art is inspired by this description and, without departing from the purpose of the present invention, designs structures and embodiments similar to this technical solution without creatively designing them, they shall fall within the scope of protection of the present invention.
