[0035] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0037] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0038] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0039] To improve the quality of drinking water and enhance its functionality, existing water purifiers not only include a water purification module, but also a cooling water module, an instant heating module, and even an ice-making module.

[0040] The water in the cold water module is usually stored in the cold water tank. The water in the cold water tank will develop an odor if it is not consumed for a long time. Since the cold water tank is located inside the water purifier and it is not convenient to pour out the cold water that has not been consumed for a long time, a reflux system is set up to allow the water in the cold water tank to flow back into the water purification module for filtration again, thereby adjusting the odor of the cold water in the cold water tank.

[0041] The recirculation system requires an additional structure to implement, but the space inside the water purifier is already very cramped. The water purifier also needs to meet the user's need for a small size so as not to take up too much counter space. It is very difficult to install the structure of the recirculation system without increasing the space occupied by the water purifier.

[0042] In a typical water purifier application scenario, suppose a multi-functional water purifier whose internal space is tightly packed with various functional modules. The cold water tank has a capacity of 5 liters, while the water purification module, containing multi-stage filters, is installed at the bottom. To achieve the recirculation function, a recirculation pump with a flow rate of 2 liters / minute needs to be installed within the limited space, and 8 mm diameter water pipes need to be laid to connect the cold water tank outlet, the recirculation pump, and the water purification module inlet. Furthermore, the power connection and control wiring layout for the recirculation pump must be considered. In this compact structure, adding any component may lead to a readjustment of the overall layout and even affect the performance of other functional modules. For example, the vibration of the recirculation pump may affect the efficiency of the refrigeration system, or the added water path may create spatial conflicts with the heating element of the instant heating module.

[0043] Failure to effectively address this technical issue will lead to several serious consequences. First, the overall size of the water purifier may have to increase, directly impacting its market competitiveness. Second, limited internal space may increase interference between functional modules, affecting the performance of core functions such as cooling, heating, and purification. For example, improper arrangement of the recirculation system could complicate the water system, increasing the risk of water contamination. Furthermore, heat accumulation in a compact space may affect cooling efficiency and even shorten the lifespan of critical components. In the long run, these problems could lead to decreased product reliability, increased maintenance difficulty, and ultimately impact user experience and market performance. Therefore, rationally arranging the recirculation system without increasing the overall size of the water purifier is a critical technical issue that urgently needs to be addressed.

[0044] In view of this, the present invention proposes a water purifier 100.

[0045] Regarding the orientation of this water purifier 100, it should be noted that when using the water purifier 100, the user generally faces the water purifier 100 to collect water. The function of the first water outlet 111 is to discharge purified water directly for the user to drink. Therefore, the side where the first water outlet 111 is located (the side facing the user) is the front side of the water purifier 100. The side to the left of the front side of the water purifier 100 is the left side of the water purifier 100, the side to the right of the front side of the water purifier 100 is the right side of the water purifier 100, and the side opposite the front side of the water purifier 100 is the rear side of the water purifier 100.

[0046] Please see Figures 1 to 3 In one embodiment of this utility model, the water purifier 100 includes a body 1, a refrigeration module 2, an instant heating module 3, a water purification module 4, and a reflux pump 6. The body 1 has an installation cavity 1a. The body 1 includes a body 11 and a base 12, with the body 11 mounted on the base 12. A first water outlet 111 is provided on the front side of the body 11. The refrigeration module 2 includes a cold water tank 21, which is installed within the installation cavity 1a. The instant heating module 3 is installed within the installation cavity 1a. The front side of the cold water tank 21; the water purification module 4 includes a filter element assembly 41 and a booster pump 42. The filter element assembly 41 is mounted on the base 12 via a mounting bracket 5. An installation space 11a is formed on the lower side of the filter element assembly 41. The booster pump 42 is mounted on the base 12 and located within the installation space 11a. The return pump 6 is mounted on the mounting bracket 5 and is adjacent to the filter element assembly 41. The return pump 6 is used to pump cold water from the cold water tank 21 into the filter element assembly 41.

[0047] It should be noted that the main body 11 is used to house and install the internal structure of the main body 11. In this embodiment, the raw water tank 10a is located on the outside of the main body 11, which makes it convenient for users to add water to the raw water tank 10a and also facilitates the replacement of wastewater and cleaning of the raw water tank 10a. The pure water tank 10b is located on the outside of the main body 11, which allows users to drink large amounts of pure water in a timely manner, thus eliminating the waiting time for the water purifier 100 to purify water. The base 12 is used to install and fix the main body 11 and some internal structures of the main body 11, especially the heavy structural components such as the booster pump 42 and the compressor 22, which are generally directly installed on the base 12. The raw water tank 10a contains water that has not been filtered by the water purification module 4, while the water in the pure water tank 10b is water that has been filtered by the water purification module 4. Therefore, the water in the raw water tank 10a flows into the pure water tank 10b after being filtered by the water purification module 4 and is stored in the pure water tank 10b for the user to pour into a water cup for drinking. The top surfaces of the main body 11, the pure water tank 10b, and the raw water tank 10a are basically on the same plane. This design makes the structure of the water purifier 100 more reasonable and allows trays, water cups, and other miscellaneous items to be placed on the water purifier 100.

[0048] The cooling module 2 is a device for cooling water, which can be implemented using a compressor 22 refrigeration system. The instant heating module 3 is a device for rapidly heating water, which can be implemented using an electric heating element. The water purification module 4 is a device for filtering and purifying water, which can be implemented using a multi-stage filter assembly 41. The return pump 6 is a device for drawing water from the cold water tank 21 back to the filter assembly 41, which can be implemented using a small water pump.

[0049] The core innovation of this application lies in mounting the reflux pump 6 on the mounting bracket 5, adjacent to the filter element assembly 41. This layout design makes full use of the space around the filter element assembly 41, avoiding additional size increases to the main body 1, while simultaneously achieving cold water recirculation. This innovative space utilization method solves the technical challenge of installing a recirculation system within a limited space.

[0050] Specifically, the working principle of this application is as follows: The body 1 serves as the outer shell of the entire water purifier 100, with an internal mounting cavity 1a for accommodating various functional modules. The body 1 consists of a body 11 and a base 12. The body 11 is mounted on the base 12 and has a first water outlet 111 on its front side. The cold water tank 21 of the cooling module 2 is installed in the mounting cavity 1a for storing and cooling water. The instant heating module 3 is installed in front of the cold water tank 21 for rapidly heating water. The water purification module 4 includes a filter element assembly 41 and a booster pump 42. The filter element assembly 41 is mounted on the base 12 via a mounting bracket 5, with an mounting space 11a formed on its lower side, where the booster pump 42 is installed. The return pump 6 is mounted on the mounting bracket 5, adjacent to the filter element assembly 41, and is used to draw water from the cold water tank 21 back to the filter element assembly 41 for further filtration.

[0051] The key to this design lies in the placement of the return pump 6. Mounting the return pump 6 on the mounting bracket 5, adjacent to the filter element assembly 41, not only saves space but also shortens the water path connection distance and improves return efficiency. This layout also facilitates maintenance and repair.

[0052] The technical solution of this utility model makes full use of the space around the filter element assembly 41 by installing the filter element on the mounting bracket 5 and installing the return pump 6 on the remaining installation space 11a of the mounting bracket 5, and making the return pump 6 adjacent to the filter element assembly 41, thus avoiding additional increase in the size of the water purifier 100 body 1. At the same time, it realizes cold water return, improves the taste of cold water stored in the cold water tank 21 for a long time, and improves the utilization rate of the internal space of the body 1 through reasonable structural design.

[0053] In one embodiment, please refer to Figure 2 and Figure 3 The mounting bracket 5 includes a first mounting bracket 515 and a second mounting bracket 525. The reflux pump 6 is mounted on the upper side of the first mounting bracket 515, and the height of the first mounting bracket 515 is greater than the height of the second mounting bracket 525.

[0054] Specifically, this design fully utilizes the internal space of the water purifier 100 by dividing the mounting bracket 5 into two sections of different heights. The first mounting bracket 515 is taller and used to install the return pump 6, while the second mounting bracket 525 is shorter and can be used to install other components or leave space. This structural design not only solves the installation problem of the return pump 6 but also improves the utilization efficiency of the internal space of the water purifier 100.

[0055] Specifically, the first mounting bracket 515 is higher than the second mounting bracket 525, allowing the return pump 6 to be installed at a higher position. This design has several advantages: First, it avoids interference between the return pump 6 and other components at the bottom, reducing layout limitations; second, the higher installation position reduces the impact of water accumulation or a humid environment at the bottom on the return pump 6, improving its service life and reliability; third, this design also provides more space for the pipe connections of the return pump 6's inlet 61 and second outlet 62, facilitating pipe layout and maintenance. This staggered design makes full use of the vertical space inside the water purifier 100, allowing for a rational layout of various components within a limited space, thereby improving the overall space utilization rate.

[0056] In practical applications, the first mounting bracket 515 and the second mounting bracket 525 can be made of different materials and have different structural designs. For example, the first mounting bracket 515 can be made of a stronger metal material to withstand the weight of the return pump 6 and the vibration during operation; while the second mounting bracket 525 can be made of a lightweight material to reduce the overall weight. The two mounting brackets 5 can be a separate design or a one-piece structure with different heights.

[0057] In one embodiment, please refer to Figure 3 and Figure 5 The return pump 6 is connected to the first mounting bracket 515 via a connector 7.

[0058] In this regard, this application further proposes that the reflux pump 6 is connected to the first mounting bracket 515 via a connector 7.

[0059] Specifically, the connector 7 can be designed in various shapes and structures to adapt to different installation requirements. For example, the connector 7 can be a U-shaped bracket, with one end fixed to the first mounting bracket 515 and the other end wrapped around and fixed to the return pump 6. Alternatively, the connector 7 can be a flat plate structure, fixed to the first mounting bracket 515 on one side and to the return pump 6 on the other side. The material of the connector 7 can be metal or high-strength plastic to ensure sufficient strength and durability.

[0060] The connection between connector 7 and the first mounting bracket 515 can be achieved through various methods such as bolt fixing, snap-fit ​​connection, or welding. These different connection methods can be selected according to actual needs and production processes to achieve the best installation effect and production efficiency.

[0061] The connection between the reflux pump 6 and the connector 7 can also be achieved in several ways. For example, a groove or snap-fit ​​structure can be designed on the connector 7 to allow the reflux pump 6 to be securely embedded therein. Alternatively, the reflux pump 6 can be directly fixed to the connector 7 with bolts. This design not only ensures the stability of the reflux pump 6 but also facilitates later maintenance and replacement.

[0062] By using connector 7, the installation position of the return pump 6 can be more flexible. The installation height and angle of the return pump 6 can be adjusted according to the actual internal space of the water purifier 100 to optimize the water circuit layout and improve the overall performance of the water purifier 100. At the same time, the design of connector 7 can also incorporate vibration damping. By adding vibration damping pads or elastic structures to connector 7, the vibration generated by the return pump 6 during operation can be effectively reduced, improving the operational stability of the water purifier 100 and reducing noise.

[0063] In one embodiment, please continue to refer to Figure 3 and Figure 5 The connector 7 includes a sleeve portion 71 sleeved to the return pump 6 and a mounting ear 72 connected to the sleeve portion 71. The mounting ear 72 is screwed to the first mounting bracket 515 by screws.

[0064] First, the socket 71 can tightly wrap around the return pump 6, providing good support and fixation. The socket 71 can be customized according to the shape of the return pump 6 to ensure a good fit with the return pump 6 and reduce shaking and displacement during installation.

[0065] Secondly, the design of the mounting ear 72 increases the contact area between the connector 7 and the first mounting bracket 515, improving the stability of the overall structure. Multiple mounting ears 72 can be designed and distributed at different positions on the socket 71 to further enhance the connection strength.

[0066] Furthermore, the mounting lug 72 is screwed onto the first mounting bracket 515, achieving a detachable installation method. This method not only ensures a secure installation but also facilitates later maintenance and replacement. When it is necessary to inspect or replace the return pump 6, simply remove the screws; the operation is simple and quick.

[0067] Furthermore, this connection method offers some adjustment flexibility. By adjusting the tightness of the screws, the installation position and angle of the return pump 6 can be fine-tuned to adapt to different installation environments and requirements.

[0068] In practical implementation, the socket 71 can be made of an elastic material, such as rubber or silicone, to increase its wrapping effect on the return pump 6 and its shock absorption effect. The mounting ear 72 can be made of a metal material, such as stainless steel or aluminum alloy, to improve strength and durability. The screws can be made of rust-resistant materials, such as stainless steel screws, to extend their service life. As a preferred embodiment, the socket 71 can be designed in a semi-cylindrical shape to match the shape of the return pump 6.

[0069] This design allows the reflux pump 6 to be securely mounted on the first mounting bracket 515, effectively solving the problems of limited installation space 11a and insufficient installation stability. At the same time, this detachable installation method facilitates later maintenance and replacement, improving the overall lifespan and maintenance efficiency of the water purifier 100.

[0070] In one embodiment, please refer to Figures 2 to 5 The axial direction of the reflux pump 6 is consistent with the height direction of the body 11. The reflux pump 6 has an inlet 61 and a second outlet 62 facing the base 12. The inlet 61 and / or the second outlet 62 are provided with a first connector 63. The first mounting bracket 515 on the side of the first connector 63 is recessed toward the filter element assembly 41 to form a first clearance space 5a.

[0071] This design offers several advantages and technical benefits. First, aligning the axis of the return pump 6 with the height of the body 11 fully utilizes the vertical space of the water purifier 100, reducing horizontal space occupation and allowing for better installation of the return pump 6 within a limited space. Second, the return pump 6 has an inlet 61 and a second outlet 62 facing the base 12. This layout simplifies water circuit connections, reduces pipe bends and length, and improves water flow efficiency while minimizing pressure loss.

[0072] Furthermore, the first connector 63 is provided at the inlet 61 and / or the second outlet 62, facilitating the connection and disassembly of the water pipes and simplifying maintenance and replacement. More importantly, the first mounting bracket 515 on the side next to the first connector 63 is recessed towards the filter element assembly 41, forming a first clearance space 5a. This design cleverly solves the problem of potential interference between the connector and the mounting bracket 5. The clearance space not only provides installation space 11a for the connector but also reduces the overall structural volume, making the installation of the recirculation system more compact.

[0073] In one embodiment, please refer to Figure 3 and Figure 4The first mounting bracket 515 includes a fixing part 511, a connecting part 512, a clearance part 513, and a bending part 514 connected in sequence. The two ends of the fixing part 511 are respectively fixed to the filter element assembly 41 and the base 12. The clearance part 513 is located beside the first connector 63. The bending part 514 and the clearance part 513 form an angle. The bending part 514 has a flange 514a. The mounting ear 72 is fixedly installed on the flange 514a.

[0074] It should be noted that this structural design has several advantages. First, the two ends of the fixing part 511 are fixed to the filter element assembly 41 and the base 12 respectively, providing stable support. The length of the connecting part 512 can be adjusted as needed to adapt to different installation spaces 11a. The arrangement of the avoidance part 513 cleverly avoids the first joint 63, ensuring smooth pipeline connection. The included angle formed between the bending part 514 and the avoidance part 513 increases the rigidity of the structure and improves the overall stability. The flange 514a on the bending part 514 provides a firm mounting point for the mounting ear 72, further enhancing the fixing effect of the return pump 6. In particular, the formation of the bending part 514 also provides a larger space for the installation of the return pump 6, thereby avoiding the problem of insufficient screw space.

[0075] This design not only solves the installation problem of the reflux pump 6, but also makes full use of the limited space. Through ingenious structural design, a stable installation of the reflux pump 6 is achieved while avoiding interference with other components. For example, the setting of the clearance part 513 ensures that the first connector 63 has sufficient operating space, facilitating pipeline connection and maintenance.

[0076] Compared with existing technologies, the design of this application has significant advantages. Traditional water purifiers 100 often struggle to rationally arrange the recirculation system within limited space, frequently resulting in complex structures, difficult installation, or inconvenient maintenance. This application, through its ingenious structural design, not only solves the space utilization problem but also improves the installation stability and maintenance convenience of the recirculation pump 6. In particular, the multi-part design of the first mounting bracket 515, with each part having a specific function, works together to form an efficient, compact, and easy-to-maintain recirculation pump 6 mounting structure. This design not only improves the overall performance of the water purifier 100 but also helps extend the equipment's service life and reduce maintenance costs.

[0077] In one embodiment, please refer to Figure 2 The flange 514a is closer to the body 11 than the fixing part 511. This arrangement of the flange 514a close to the body 11 reflects that although the return pump 6 is close to the outer shell of the body 11, it still maintains a certain distance, which can improve the internal structural compactness of the body 11.

[0078] In one embodiment, please refer to Figure 2 and Figure 3 The filter element assembly 41 has a water channel plate 8 on its lower side. The water channel plate 8 has a second connector 81 facing the fixing part 511. The fixing part 511 has an opening 511a to allow the second connector 81 to pass through. The second connector 81 is connected to a first connector 63.

[0079] Specifically, the water channel plate 8, as part of the filter element assembly 41, serves to connect and distribute water flow. The second connector 81 on the water channel plate 8 faces the fixing part 511, allowing for easy connection with the opening 511a on the fixing part 511. The opening 511a on the fixing part 511 allows the second connector 81 to pass through, thereby communicating with the first connector 63 on the return pump 6. This design creates a complete water loop from the filter element assembly 41 to the return pump 6.

[0080] Furthermore, the second connector 81 can be designed as a quick-connect coupling, such as a snap-fit ​​or threaded connector, for easy installation and disassembly. The size of the opening 511a can be slightly larger than the outer diameter of the second connector 81 to facilitate adjustment and installation. To ensure a tight seal, a sealing ring or gasket can be placed between the second connector 81 and the opening 511a.

[0081] Thus, after water flows out of the filter element assembly 41, it passes through the second connector 81 on the water circuit plate 8, through the opening 511a on the fixing part 511, and then connects to the first connector 63 on the return pump 6. This design not only ensures the continuity of the water circuit but also facilitates maintenance and component replacement. For example, when the filter element needs to be replaced, the filter element assembly 41 can be easily removed simply by disconnecting the connection between the second connector 81 and the first connector 63.

[0082] As a preferred embodiment, the second connector 81 can be made of an elastic material, such as food-grade silicone or rubber, which can provide a certain degree of cushioning while ensuring sealing and reducing the impact of vibration on the connection. Furthermore, the second connector 81 can be designed as a rotatable structure to accommodate different installation angles.

[0083] This design not only solves the connection problem between the filter element assembly 41 and the return pump 6, but also improves the integration and compactness of the entire system. Compared with traditional connection methods, the solution of this application reduces the use of piping, lowers the risk of leakage, and facilitates maintenance and cleaning. In addition, this design can effectively reduce the space occupied inside the water purifier 100, which is conducive to achieving a more compact overall layout.

[0084] In one embodiment, please refer to Figure 2The filter assembly 41 includes a first filter element 411 and a second filter element 412 arranged side by side, and the axial direction of the first filter element 411 and the second filter element 412 is consistent with the height direction of the water purifier 100.

[0085] In the water purifier 100 of this application, the filter element assembly 41 includes a first filter element 411 and a second filter element 412 arranged side by side, with the axial direction of the first filter element 411 and the second filter element 412 aligned with the height direction of the water purifier 100. This design can effectively utilize the vertical space of the water purifier 100, making the arrangement of the filter element assembly 41 more compact and efficient.

[0086] Specifically, arranging the first filter element 411 and the second filter element 412 side by side reduces the horizontal space occupied by the water purifier 100, while aligning their axes with the vertical direction of the water purifier 100 makes full use of the vertical space of the water purifier 100. This arrangement not only saves space but also simplifies water circuit connections and improves water purification efficiency.

[0087] The first filter element 411 is designed as a composite filter element combining a pre-filter and a post-filter, used to remove larger particles and suspended solids from the water. The post-filter element can also be used to adjust the taste of the water. The second filter element 412 can be designed as a reverse osmosis filter element to further remove tiny impurities and water-soluble salt ions from the water. This parallel arrangement allows water to pass through the two filter elements sequentially, achieving a more comprehensive purification effect.

[0088] Furthermore, the parallel arrangement of the first filter element 411 and the second filter element 412 can optimize the weight distribution of the water purifier 100 and improve its overall stability. Since the weight of the two filter elements is distributed on both sides of the water purifier 100, the imbalance problem caused by excessive weight on one side can be avoided.

[0089] In one embodiment, please refer to Figure 2 and Figure 3 The water purification module 4 also includes an inlet solenoid valve 43 and a wastewater solenoid valve 44. The inlet solenoid valve 43 and the wastewater solenoid valve 44 are both fixed on the base 12 by a support frame 45. The inlet solenoid valve 43 and the wastewater solenoid valve 44 are located between the filter element assembly 41 and the return pump 6.

[0090] Based on the above embodiments, the water purification module 4 of this application further includes an inlet solenoid valve 43 and a wastewater solenoid valve 44. Both the inlet solenoid valve 43 and the wastewater solenoid valve 44 are fixed to the base 12 by a support frame 45, and are located between the filter element assembly 41 and the return pump 6. This arrangement makes full use of the space between the filter element assembly 41 and the return pump 6, effectively solving the problem of limited installation space 11a for the return system.

[0091] Specifically, the inlet solenoid valve 43 controls the flow rate of raw water into the water purification module 4, and the wastewater solenoid valve 44 controls the discharge of wastewater generated during the water purification process. Fixing these two solenoid valves to the base 12 via the support frame 45 ensures their stability. Furthermore, placing them between the filter cartridge assembly 41 and the return pump 6 makes full use of the space in this area, avoiding the occupation of space for other functional modules.

[0092] This arrangement also simplifies water circuit connections. The inlet solenoid valve 43 can be directly connected to the inlet 61 of the filter element assembly 41, while the wastewater solenoid valve 44 can be connected to the wastewater outlet of the filter element assembly 41. This reduces the length and complexity of the piping, further saving space. Furthermore, the two solenoid valves only require one support frame 45 for installation, simplifying the installation steps and structure.

[0093] In one embodiment, please refer to Figure 6 and Figure 7 The refrigeration module 2 also includes a compressor 22 and a heat dissipation component 23, which are fixed to the base 12. The cold water tank 21 is installed on the upper side of the compressor 22 and the heat dissipation component 23.

[0094] It should be noted that the lower part of the cold water tank 21 has sufficient installation space 11a. In order to reduce the piping, the compressor 22 and heat dissipation assembly 23, which are used for heat exchange with the cold water tank 21, are placed below the cold water tank 21. This reduces the length of the piping and forms a more compact refrigeration module 2 that occupies less space. Furthermore, the compressor 22 vibrates significantly during operation. The compressor 22 can be mounted on the base 12 with vibration damping pads to reduce the vibration amplitude of the compressor 22.

[0095] In one embodiment, please refer to Figure 7 The cold water tank 21 is equipped with an ice-making module. The front side of the body 1 is provided with an ice outlet 112, which is located next to the first water outlet 111. The cold water tank 21 includes a main body 211 and an ice outlet channel 212 protruding toward the ice outlet 112. The instant heating module 3 is installed on the front side of the main body 211 and is located below the ice outlet channel 212.

[0096] It should be noted that an ice-making module is provided on the upper side of the cold water tank 21, and the ice-making module has an ice outlet 112, which is located next to the first water outlet 111. In this way, the remaining cold water after the ice-making module can flow into the lower part of the cold water tank 21. Considering that the ice-making channel is relatively long and the ice-making module protrudes from the main body 211 of the cold water tank 21, the instant heating module 3 is installed on the front side of the main body 211 and located on the lower side of the ice outlet channel 212, making full use of the installation space 11a on the lower side of the ice outlet channel 212.

[0097] Optionally, please refer to Figure 6 The water purifier 100 also includes an electronic control module 9. A second clearance space 211a is formed by a recess on one side of the main housing 211. The electronic control module 9 is installed in the main housing 211 and is at least partially located in the second clearance space 211a.

[0098] Additionally, a recessed space is provided on one side of the main housing 211 to allow the electronic control module 9 to be installed within the main housing 211. The electronic control module 9 is located between the main housing 211 and the water tank housing 113, keeping it away from the water path and preventing interference from the water path that could lead to corrosion of the circuit board. This design effectively utilizes the installation space 11a within the mounting cavity 1a.

[0099] In one embodiment, please refer to Figure 1 and 8 The body 11 has a water tank accommodating position 113 on the left or right side. The water purifier 100 also includes a raw water tank 10a and a pure water tank 10b, both of which are housed in the water tank accommodating position 113.

[0100] The distribution of the raw water tank 10a and the purified water tank 10b can be further optimized. For example, the raw water tank 10a and the purified water tank 10b can be located on the same side of the body 11, or on different sides of the body 11. As a preferred embodiment, in this example, to save space occupied by the water purifier 100, especially the space occupied by the water purifier 100 in its front-to-back direction, the raw water tank 10a and the purified water tank 10b are placed on the same side of the body 11, thereby further reducing the space occupied by the water purifier 100 on the countertop. Furthermore, the detachable design of the purified water tank 10b can be achieved in various ways. For example, the purified water tank 10b can be connected to the body 11 by means of clips, slide rails, or magnets, facilitating user disassembly and installation. The raw water tank 10a can also be detachably mounted on the body 10b. Specifically, the raw water tank 10a and the purified water tank 10b can be located on the left side or the right side of the body 11, depending on actual needs. The same technical effect can be achieved by setting the raw water tank 10a and the pure water tank 10b on the left side of the body 11 or on the right side of the body 11.

[0101] By uniformly placing the raw water tank 10a and the purified water tank 10b on one side of the main body 11, the internal structural layout of the main body 11 is simplified, and the space occupied in the left and right directions of the main body 11 is reduced. This solves the technical problem of distributing the raw water tank 10a and the purified water tank 10b in the left and right directions of the main body 11. Compared with the prior art, the technical solution of this application optimizes the space utilization inside the main body 11 while maintaining the function of the water purifier 100, making the space occupied by the water purifier 100 on the countertop more compact, especially suitable for tables or counters with limited space.

[0102] In one embodiment, please refer to Figure 1 The pure water tank 10b is located in front of the raw water tank 10a, and a handle is provided on the front side of the pure water tank 10b.

[0103] The handle on the front of the pure water tank 10b can take various forms; for example, it can be recessed or protruding. Specifically, a recessed handle can be designed as a groove, while a protruding handle can be designed as an arc or a straight line. As a preferred embodiment, the handle can be made of a non-slip material to increase user comfort and stability. Furthermore, the position of the handle can be adjusted according to the overall design of the pure water tank 10b; for example, the handle can be located on the top or side of the pure water tank 10b to facilitate disassembly and movement by the user at different angles.

[0104] Therefore, this technical solution, by placing the pure water tank 10b in front of the original water tank 10a and equipping it with a handle, effectively reduces the vertical space occupied by the water purifier 100 on the countertop, especially on tables or counters with limited space, allowing for better accommodation of the water purifier 100. The handle on the front of the pure water tank 10b facilitates user disassembly and movement of the pure water tank 10b, further improving ease of use. Through this layout and design, this application effectively solves the problem of the pure water tank 10b occupying too much space on the outside of the water purifier 100 body 11, while improving the user experience. Compared with the prior art, this application has significant advantages in terms of space utilization and user operation convenience.

[0105] In one embodiment, please refer to Figure 8 and Figure 9 The body 1 also includes a partition 13, which is installed between the pure water tank 10b and the raw water tank 10a.

[0106] The partition 13 can be made of various materials, such as plastic, metal, or composite materials. The specific material selection can be optimized based on the overall structure of the body 11 and the strength requirements of the partition 13. The shape and size of the partition 13 can be adjusted according to the specific layout of the pure water tank 10b and the raw water tank 10a to ensure effective separation between them. As a preferred embodiment, the partition 13 can be designed as a detachable structure for easy cleaning and maintenance by the user. Furthermore, the partition 13 can be installed using various methods such as snap-fit, screw fixing, or adhesive bonding. The specific installation method can be selected based on the internal structure of the body 11 and the material of the partition 13.

[0107] By using partition 13, the spatial layout between the pure water tank 10b and the raw water tank 10a is effectively optimized, preventing mutual interference when the two tanks are removed and placed. Partition 13 not only ensures the orderly arrangement of the pure water tank 10b and the raw water tank 10a within the unit 11, but also improves the overall structural compactness and operational efficiency of the water purifier 100. Compared with existing technologies, the technical solution of this application, through the introduction of partition 13, solves the technical problem of unreasonable spatial layout between the pure water tank 10b and the raw water tank 10a, enabling the water purifier 100 to better adapt to and be installed even in confined spaces.

[0108] In one embodiment, please refer to Figure 9 The maximum length of the water purifier 100 in its front-to-back direction is L, and the maximum width of the water purifier 100 in its left-to-right direction is T. The L and T satisfy 1≤L / T≤1.4.

[0109] Specifically, the L / T ratio is limited to between 1 and 1.4. This design allows the water purifier 100 to optimize its countertop space usage while maintaining functionality. For example, when L / T is 1, the dimensions of the water purifier 100 are equal in both the front-to-back and left-to-right directions, forming a more compact structure. When L / T is 1.4, the length of the water purifier 100 in the front-to-back direction is slightly greater than its width in the left-to-right direction, but still within a reasonable range, avoiding excessive space occupation. As a preferred embodiment, the L / T ratio can be further optimized to between 1.2 and 1.3 to achieve a better balance between compactness and functionality.

[0110] Therefore, this technical solution, by limiting the ratio of L to T, makes the water purifier 100 more suitable for environments with limited space, solving the problem of excessive space occupation caused by unreasonable size ratios in existing technologies. Compared with existing technologies, this solution significantly optimizes the space occupation of the water purifier 100 while maintaining its functionality, making it more suitable for use in limited countertop space.

[0111] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
