[0061] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the description of this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0062] Please refer to Figures 1 to 3 , this application proposes a combined water purification and heating machine 1. In the embodiment of this application, the combined water purification and heating machine 1 includes a housing assembly 10, a water circuit board 60, a filtration system 50, and a hot water tank assembly 20.

[0063] Among them, the housing assembly 10 serves as the external framework of the entire combined water purification and heating machine 1, and its overall outer contour is set in a rectangular shape. It is particularly suitable for installation and placement in the kitchen area. The kitchen usually has regular cabinet space, and the rectangular combined water purification and heating machine 1 can be easily embedded under the cabinet or placed in the corner of the kitchen countertop, integrating with the overall kitchen environment.

[0064] The water circuit board 60 is used to provide a water flow channel so that the purified water filtered by the filtration system 50 can flow to the hot water tank assembly 20 for heating. At the same time, the water flow channel of the water circuit board 60 can also discharge the filtered wastewater. By arranging the water circuit board 60 inside the housing assembly 10, the protective performance of the housing assembly 10 is fully utilized to protect the water circuit board 60. And multiple water flow channels can be provided inside the water circuit board 60. Compared with the traditional decentralized water pipe connection, the installation is more convenient and fast. In terms of the material of the water circuit board 60, a high-strength and corrosion-resistant composite material is selected. This material not only has excellent anti-chemical erosion ability and can effectively resist the corrosion of various acid and alkaline substances that may exist in the water to the water circuit board 60, but also its unique molecular structure enables the water circuit board 60 to maintain the integrity of the structure and the stability of the dimensions under the long-term action of water flow pressure and temperature changes, thereby ensuring the smoothness of the water flow channel.

[0065] Refer to Figure 4, in some embodiments, the waterway board 60 includes a first waterway board 61 and a second waterway board 62 that are connected and communicate with each other. The filtration system 50 and the hot water tank assembly 20 are respectively located on opposite sides of the first waterway board 61, and the second waterway board 62 is arranged at an angle with the first waterway board 61. Specifically, the second waterway board 62 and the first waterway board 61 can be arranged at a perpendicular 90-degree angle. This standardized 90-degree angle design facilitates the development of molds and the standardization of production processes, reduces production costs and production cycles, and at the same time makes it convenient for maintenance personnel to quickly locate and replace the components of the waterway board 60 when the equipment fails, reducing maintenance time and costs. Of course, the angle between the first waterway board 61 and the second waterway board 62 can also be 70°, 80°, 100°, 110°, etc. Such a setting optimizes the utilization of the internal space and performance of the housing assembly 10, can be flexibly arranged according to the actual space form inside the housing assembly 10, effectively adapts to the installation positions of the filtration system 50 and the hot water tank assembly 20, avoids the problem of space waste caused by the limited structure of the traditional waterway board 60, makes the connection between components more compact and efficient, reduces unnecessary pipeline length and complexity, reduces water flow resistance, thereby improving the water purification efficiency and water flow stability, reduces the hidden danger of water leakage, and ensures the reliable operation of the integrated water purification and heating machine 1.

[0066] The filtration system 50 is a key part of the integrated water purifier and heater 1. By being installed inside the housing assembly 10, it makes full use of the protective performance of the housing, avoiding the interference of dust, water vapor and other possible pollutants to the filtration process, thus ensuring the reliability and stability of the filtration effect. The filtration system 50 and the hot water tank assembly 20 are connected through the water circuit board 60. The filtration system 50 includes a primary filter element 51, a secondary filter element 52 and a booster pump 53. The primary filter element 51 and the secondary filter element 52 are connected and communicated through the water circuit board 60. The booster pump 53 is used to transport the liquid filtered by the primary filter element 51 to the secondary filter element 52 through the water circuit board 60. The primary filter element 51 can be PAC (Polyaluminium Chloride). As a primary filtration unit, it mainly intercepts and removes larger particulate impurities, suspended solids, some colloids and some microorganisms in water. The filtration material it uses has a larger pore size and surface area, which can efficiently capture these larger pollutants and prevent them from entering the subsequent filtration links, thus protecting the secondary filter element 52 from excessive blockage and pollution and extending the service life of the entire filtration system 50. The booster pump 53 plays an important role as the power in the filtration system 50. Its main function is to provide sufficient pressure for the water filtration process to ensure that the water preliminarily filtered by the primary filter element 51 can enter the secondary filter element 52 for deep purification through the water circuit board 60 or water pipes at a stable and appropriate flow rate. The water preliminarily filtered by the primary filter element 51 is transported to the secondary filter element 52 through the water circuit board 60 under the action of the booster pump 53. The secondary filter element 52 can be RO (Reverse Osmosis), which is the key link for achieving deep purification. It uses a more refined filtration material and can effectively remove harmful substances such as residual fine particles, dissolved organic matter, heavy metal ions, bacteria and viruses in water. These tiny pollutants often pose a potential threat to human health. Through the fine filtration of the secondary filter element 52, it can ensure the provision of safe, pure and healthy drinking water for users.

[0067] The hot water tank assembly 20 is used to store and heat the filtered pure water, so as to meet the user's demand for hot water at any time, improving the functionality and practicality of the device.

[0068] In addition, the integrated water purifier and water heater 1 further includes a water pump 30. The water pump 30 is disposed within the housing assembly 10 and is in communication with the water circuit board 60. Thus, by virtue of the water pumping performance of the water pump 30, the hot water in the hot water tank assembly 20 is pumped out and discharged through the water circuit board 60, so that the integrated water purifier and water heater 1 can provide efficient and stable water supply services, and users do not need to worry about affecting normal domestic water use due to insufficient water pressure or unstable water flow. An inlet valve 63, a check valve 64, a waste water plug 65, and a water replenishing valve 66 can also be installed on the water circuit board 60. The inlet valve 63 is used to control the conduction of the water circuit entering the filtration system 50 on the water circuit board 60. The check valve 64 is located between the filtration system 50 and the hot water tank assembly 20 to prevent the filtered water flow from flowing back. With reference to Figure 5 , the water flow path of this application is as follows: Tap water first flows into the water circuit board 60 from the interface of the water circuit board 60, and then undergoes primary filtration through the primary filter element 51. Subsequently, driven by the booster pump 53, the water flow passes through the secondary filter element 52 for secondary filtration. The waste water after two-stage filtration is discharged through the waste water plug 65, while the pure water is split into two paths through the check valve 64. One path can supply an external pipeline machine 3 to directly output normal temperature water; the other path flows to the hot water tank assembly 20 after the water replenishing valve 66 is opened and becomes hot water under the heating effect of the hot water tank assembly 20.

[0069] In addition, the integrated water purifier and water heater may further include a faucet 2. The faucet 2 is connected to the housing assembly 10 and is in communication with the hot water tank assembly 20 and the filtration system 50. When the faucet 2 is opened, the hot water in the hot water tank assembly 20 or the normal temperature water in the filtration system 50 can flow out through the faucet 2 to provide hot water or normal temperature water for users. It can be understood that the integrated water purifier and water heater 1 can have two faucets 2. One faucet 2 is in communication with the hot water tank assembly 20, and the other faucet 2 is in communication with the filtration system 50, so that hot water and normal temperature water can be provided for users separately. In other embodiments, the faucet 2 can also be in communication with the hot water tank assembly 20 and the filtration system 50 respectively, and the switch is used to control the faucet 2 to flow out hot water or normal temperature water.

[0070] It can be understood that the faucet 2 can also be an intelligent faucet 2. When the controller detects a signal for taking normal temperature water or a water replenishing signal of the hot water tank assembly 20 at the intelligent faucet 2, the controller can control the filtration system 50 to start water production to ensure that users can obtain normal temperature water and hot water from the intelligent faucet 2 in a timely manner, reduce the waiting time of users, and improve the user experience.

[0071] The hot water tank assembly 20 is in communication with the faucet 2 and is in communication with the filtration system 50. It can heat the normal temperature water filtered by the filtration system 50 and provide hot water for users after the faucet 2 is opened.

[0072] It can be understood that the faucet 2 can also be installed near the operation panel and communicated with the hot water tank assembly 20 and the filtration system 50 through pipelines, so that the user can control the water outlet of the faucet 2 through the operation panel, and thus it is convenient for the user to obtain hot water and normal temperature water from the faucet 2.

[0073] In addition, the integrated water purifier and water heater 1 of the present application can also realize the function of enabling the user to obtain water at a set temperature, that is, the user can also obtain the function of warm water with a temperature between the normal temperature water and the hot water discharged from the hot water tank assembly 20 from the faucet 2. For this purpose, the integrated water purifier and water heater 1 of the present application can further include a first temperature sensor and a second temperature sensor. The first temperature sensor is connected to the tank body 21 and is arranged in the heating cavity 21A for detecting the temperature of the hot water in the heating cavity 21A. The second temperature sensor is arranged in the pure water pipeline for detecting the normal temperature of the normal temperature water in the pure water pipeline. Both the first temperature sensor and the second temperature sensor are connected to the controller. The controller can receive the detection values of the first temperature sensor and the second temperature sensor and control the operating power of the water extraction pump 30 and the booster pump 53 to form warm water with a set temperature value at the faucet 2. It can be understood that the first temperature sensor can also be arranged in the water outlet pipe of the tank body 21 to detect the temperature of the hot water in the water outlet pipe of the tank body 21.

[0074] It can be understood that a warm water control device can be arranged on the operation panel. The warm water control device includes at least one of a button, a knob, a touch screen, etc. The user can operate the warm water control device to select the required warm water temperature, so that the faucet 2 can discharge warm water at the temperature selected by the user to meet the user's use requirements.

[0075] In the embodiment of the present application, taking the selection of 45°C warm water and 55°C warm water as an example, the specific method steps are explained.

[0076] When the user selects the warm water temperature through the warm water control device, the controller obtains the temperature selection signal of the warm water; if the temperature selection signal is a 45°C warm water signal, the controller controls the booster pump 53 to adjust the duty ratio to 85%. The controller obtains the current normal temperature water temperature through the first temperature sensor and obtains the current hot water temperature through the second temperature sensor, calculates the first output duty ratio of the water extraction pump 30 according to the first preset formula, and the controller adjusts the output duty ratio of the water extraction pump 30 according to the value of the first output duty ratio. At this time, 45°C warm water can flow out from the water outlet of the faucet 2; when the controller detects that the water level in the tank body 21 drops to the low water level, or when the controller receives the closing signal of the faucet 2, the controller controls the water outlet of the faucet 2 to stop discharging water.

[0077] If the temperature selection signal is not the 45°C warm water signal, it indicates that the user selects 55°C warm water. The controller controls the booster pump 53 to adjust the duty cycle to 75%. The controller obtains the current temperature of the normal temperature water through the first temperature sensor and obtains the current temperature of the hot water through the second temperature sensor. The second output duty cycle of the water pump 30 is calculated according to the second preset formula. The controller adjusts the output duty cycle of the water pump 30 according to the second output duty cycle value. At this time, 55°C warm water can flow out from the water outlet of the faucet 2; when the controller detects that the water level in the tank body 21 drops to the low water level, or when the controller receives the closing signal of the faucet 2, the controller controls the water outlet of the faucet 2 to stop discharging water.

[0078] It can be understood that in other embodiments, the operation panel can also provide other warm water temperature selections, such as 35°C, 50°C, and 60°C, etc. In the embodiments of the present application, no specific restrictions are made in this regard.

[0079] However, due to the numerous components of the filtration system 50 and the hot tank assembly 20 and the lack of systematicity in the installation sequence, problems such as limited operation space, inaccurate positioning of components, and difficulty in immediate debugging and detection often occur during the assembly process, resulting in low assembly efficiency and low product qualification rate. To solve the above problems, the housing assembly 10 of the present application includes a middle shell 12 and an outer shell 10A. The outer shell 10A is framed around the outer periphery of the middle shell 12. The water circuit board 60, the filtration system 50, and the hot tank assembly 20 are all connected to the middle shell 12.

[0080] Based on the above embodiments, by adopting the housing assembly 10 including the middle shell 12 and the outer shell 10A, and connecting the water circuit board 60, the filtration system 50, and the hot tank assembly 20 to the middle shell 12, the assembly process and performance of the integrated water purifier and water heater 1 are greatly optimized. In terms of assembly, the middle shell 12 provides a stable and relatively independent assembly platform for each component, solving the assembly problems caused by limited operation space. Workers can more conveniently and accurately position and install the filtration system 50 and the hot tank assembly 20, improving the assembly efficiency and accuracy. Compared with directly assembling inside the outer shell 10A, operating on the middle shell 12 can reduce the inconvenience caused by the shape and space limitations of the outer shell 10A.

[0081] Meanwhile, this connection method facilitates immediate debugging and detection of each component during the assembly process. That is, after the filtration system 50 and the hot water tank assembly 20 are installed on the middle shell 12, preliminary debugging and detection can be carried out on some functional modules on the middle shell 12, enabling potential problems to be discovered and solved in a timely manner, reducing the workload of rework and repair, effectively improving the product qualification rate, and lowering the production cost. In contrast, if the detection is carried out after the outer shell 10A is closed, once a problem is found, the outer shell 10A needs to be disassembled for repair, which will increase the difficulty and cost of repair. From a performance perspective, the stable assembly structure ensures the connection reliability between the water circuit board 60, the filtration system 50, and the hot water tank assembly 20, ensuring the stable transmission of water flow and the effective utilization of heat, enhancing the overall operating stability and reliability of the device, and thus providing users with a more stable and efficient integrated water purification and heating function experience.

[0082] It should be noted that the outer shell 10A and the middle shell 12 are fixed by means of screws or buckles, etc., to ensure a tight fit, maintain the stability and protection of the overall structure, and protect the internal components from external factors. It should be noted that the outer shell 10A may include a front panel 11, a back panel 13, a top panel 14, side panels 16, and a bottom panel 15. The front panel 11 is located on the front of the integrated water purification and heating machine 1 and is provided with components such as an operation interface and indicator lights. Of course, the control interface of the integrated water purification and heating machine 1 can be installed on the faucet 2 or controlled through a mobile phone control terminal. The back panel 13 is located at the rear of the integrated water purification and heating machine 1 and is closely connected to the side panels 16 to enclose the rear of the integrated water purification and heating machine 1. The top panel 14 is located at the top of the integrated water purification and heating machine 1, and the side panels 16 surround both sides of the integrated water purification and heating machine 1 and are seamlessly connected to other panels. The bottom panel 15 bears the weight of the integrated water purification and heating machine 1 and isolates the influence of the ground.

[0083] With reference to Figure 6 , in some embodiments, the middle shell 12 includes a base plate 121, a water circuit board support seat 122, and a filtration support seat 123. The base plate 121 includes an installation surface and an abutting surface arranged opposite to each other. The abutting surface is fixedly abutted against the inner wall of the outer shell 10A, and the hot water tank assembly 20 is connected to the installation surface. Among them, as a basic component, the installation surface and the abutting surface arranged opposite to each other on the base plate 121 play a key role. The abutting surface is fixedly abutted tightly against the inner wall of the outer shell 10A, forming a stable connection structure, effectively enhancing the compressive capacity of the entire housing assembly 10, enabling the integrated water purification and heating machine 1 to better protect the internal components from damage when subjected to external pressure or collision, thereby extending the service life of the integrated water purification and heating machine 1 and reducing the maintenance cost and replacement frequency caused by the failure of the integrated water purification and heating machine 1 for users. The hot water tank assembly 20 can be fixed to the installation surface by means of screw connection or snap connection, etc.

[0084] The waterway board support seat 122 is connected to the mounting surface, and the waterway board 60 is connected to the waterway board support seat 122. After the waterway board 60 is connected to the waterway board support seat 122, it can maintain a stable working state and avoid displacement or deformation due to its own weight or water flow impact. The stable waterway board 60 can ensure the smoothness of the internal flow channel, reduce the water flow resistance, improve the water transmission efficiency, make the water purification process more efficient and fast, and meet the user's demand for stable water supply. Moreover, the accurate support positioning helps to improve the connection accuracy between the waterway board 60 and other components, further reduce the risk of water leakage, and ensure the sealing and reliability of the entire water purification system.

[0085] The filter support seat 123 is connected to the mounting surface and is spaced from the waterway board support seat 122, and the filter system 50 is connected to the filter support seat 123. This provides a dedicated installation position for the filter system 50. After the filter system 50 is connected to the filter support seat 123, it can work in a relatively stable and independent space, reduce the interference of external factors on the filtering process, and ensure the stability and reliability of the filtering effect. At the same time, the spaced structure is conducive to optimizing the internal space layout of the device, making the connection between components more reasonable and compact, facilitating the installation, maintenance and repair of the device. Maintenance personnel can more conveniently perform operations such as filter element replacement and cleaning on the filter system 50, reducing the maintenance difficulty and cost, and improving the maintainability of the device.

[0086] The above settings make the waterway board 60, the filter system 50 and the hot water tank assembly 20 all located on one side of the mounting surface of the substrate 121. From the perspective of the convenience of production and assembly, concentrating these key components on the same side of the mounting surface of the substrate 121, this layout allows workers to complete the installation of components such as the waterway board 60, the filter system 50 and the hot water tank assembly 20 in sequence in a relatively fixed position and direction, without complex flipping operations, greatly shortening the assembly time, reducing the labor input, and improving the production efficiency. In terms of the overall stability and reliability of the device, this same-side layout also plays an important role. Since the relative positions between components such as the waterway board 60, the filter system 50 and the hot water tank assembly 20 are closer and more stable after installation, problems such as connection loosening and displacement that may occur due to components being distributed on different sides are reduced.

[0087] Furthermore, the middle shell 12 further includes a retaining wall 124, which is connected to the edge of the mounting surface. The water circuit board support seat 122, the filter support seat 123, the substrate 121, and several retaining walls 124 enclose a cavity 10a, and both the hot water tank assembly 20 and the water circuit board 60 are located in the cavity 10a. From the perspective of the overall structure of the device, the presence of the retaining wall 124 further improves the structural integrity of the middle shell 12 and enhances the protection ability for internal components. It can effectively block the entry of external dust, water vapor, and other possible impurities into the cavity 10a. The cavity 10a provides a relatively stable and independent working environment for the hot water tank assembly 20 and the water circuit board 60. Due to the space formed by the tight enclosure of each component, the interference of external factors on the hot water tank assembly 20 and the water circuit board 60 is reduced. In addition, when maintenance or repair of the device is required, the presence of the cavity 10a enables maintenance personnel to more clearly locate and operate the hot water tank assembly 20, the water circuit board 60, and their related components. Compared with devices with an open or loose structure, the enclosed cavity 10a reduces the difficulty of component search and fault troubleshooting, improves the repair efficiency, and reduces the maintenance cost and time.

[0088] With reference to Figure 3 、 Figure 4 and Figure 7 , in some embodiments, the integrated water purification and heating device 1 further includes a heat insulation member 70, which is disposed in the housing assembly 10 and divides the cavity 10a of the housing assembly 10 into a filter element cavity 104 and a hot water tank cavity 103. The filtration system 50 is located in the filter element cavity 104, and the hot water tank assembly 20 is located in the hot water tank cavity 103. By providing the heat insulation member 70 to divide the cavity 10a of the housing assembly 10 into the filter element cavity 104 and the hot water tank cavity 103, on the one hand, it effectively blocks a large amount of heat generated during the operation of the hot water tank assembly 20 from radiating to the filtration system 50, avoiding problems such as accelerated aging of the filter material, reduced filtration efficiency and accuracy caused by heat radiation, and ensuring that the filtration system 50 can maintain high filtration performance stably for a long time, thereby continuously and stably providing clean and safe drinking water for users. On the other hand, due to the heat insulation effect of the heat insulation member 70 on the hot water tank assembly 20, the temperature influence of heat on the normal temperature water is weakened, enabling the normal temperature water to maintain within an appropriate temperature range, ensuring the user's demand for the quality of the normal temperature water, and avoiding problems such as water quality change and taste change caused by the increase in the temperature of the normal temperature water. At the same time, it prevents the deformation and damage of the internal sealing material of the filtration system 50 and the interference of sensitive electronic components or sensors caused by high temperature, reduces the occurrence probability of equipment leakage faults, improves the overall operation stability and safety of the device, reduces the user's usage cost and maintenance frequency, and brings a more reliable and convenient usage experience to the user.

[0089] Furthermore, the heat insulation member 70 includes a heat insulation cover 71 which is detachably connected to the middle shell 12 and encloses a heat storage cavity 103 with the middle shell 12. The heat insulation cover 71 can effectively reduce the heat dissipation of the heat storage assembly 20 to the surrounding environment and improve the utilization efficiency of heat. Compared with the traditional heat insulation material smeared on the heat storage assembly 20, the heat insulation cover 71 has better integrity and stability. The smeared heat insulation material may crack, peel off, etc. over time, thus reducing the heat insulation effect. However, the heat insulation cover 71, as an independent structural component, can always maintain its complete heat insulation performance, effectively block the heat dissipation of the heat storage assembly 20 to the surrounding environment, and improve the utilization efficiency of heat. At the same time, compared with some embedded heat insulation structures, the detachable feature of the heat insulation cover 71 provides great convenience for maintenance personnel. When the heat storage assembly 20 fails and needs to be repaired or replaced, the maintenance operation of the embedded heat insulation structure is often extremely complex. A large number of surrounding components may need to be removed to access the heat storage assembly 20. In contrast, the heat insulation cover 71 can be easily detached from the middle shell 12, and the heat storage assembly 20 can be directly operated without having to difficultly search for and handle faulty components in the complex heat insulation structure, greatly shortening the maintenance time and downtime, and improving the availability and maintenance efficiency of the equipment. In addition, the heat insulation member 70 may further include a heat insulation layer attached to the inside of the middle shell 12 to further improve the heat insulation effect.

[0090] Furthermore, the enclosure 124, the base plate 121, the filter support seat 123, and the water circuit board support seat 122 are an integral member. Such an integrated design greatly enhances the overall strength and rigidity of the middle shell 12. There are no connection gaps or weak points between the parts, enabling the middle shell 12 to more firmly bear the weights of the internal water tank, the water circuit board 60, and the filtration system 50, as well as external impact forces and vibrations, effectively preventing component deformation, displacement, or damage caused by long-term use or accidental collisions, ensuring the stable operation of the precision components inside the equipment, reducing the probability of equipment failures, and extending the service life of the equipment.

[0091] Refer to Figure 6 and Figure 7, in some structural forms, the filter support seat 123 and the waterway board support seat 122 are arranged in sequence along the front-back direction of the housing 10A, and the hot water tank assembly 20 is located on the side of the waterway board support seat 122 away from the filter support seat 123. In this way, the filter support seat 123 being arranged away from the hot water tank assembly 20 can effectively reduce the high-temperature influence of the hot water tank assembly 20 on the filtration system 50. Since the hot water tank assembly 20 generates heat during operation, if it is too close to the filtration system 50, the high-temperature environment may have a negative impact on the performance of the filter material. By keeping a certain distance between the filter support seat 123 and the hot water tank assembly 20, the filtration system 50 can be in a relatively stable and suitable temperature environment, ensuring the stable performance of the filter material, maintaining an efficient filtration effect, extending the overall service life of the filtration system 50, reducing the user's usage cost and maintenance cost, and enhancing the reliability and durability of the product.

[0092] Furthermore, an installation cavity 1231 is provided in the filter support seat 123, and an installation opening 1232 communicating with the installation cavity 1231 is opened on the side of the filter support seat 123 facing away from the waterway board support seat 122. The installation opening 1232 is used for the filter element of the filtration system 50 to pass through and be installed in the installation cavity 1231. It can be understood that when the filter element passes through and is fixed in the installation cavity 1231 through the installation opening 1232, the filter element and the filter support seat 123 form a tightly combined integral structure. In this way, it can effectively prevent the filter element from being displaced, loosened or even damaged due to water flow impact, equipment vibration or other external factors, thereby ensuring the stability and reliability of the filtration system 50 and enabling the filtration process to proceed continuously and efficiently. From the perspective of long-term use, the stable filter element installation method reduces the risk of wear and leakage of the filter medium caused by frequent shaking or displacement of the filter element, extends the service life of the filter element, and reduces the frequency and cost of the user replacing the filter element. At the same time, the stable filtration process also ensures the stability of the purified water quality, provides a solid foundation for the stable operation of the subsequent waterway board 60 and the entire hot and clean water integrated machine 1, reduces the potential damage to other components of the equipment caused by water quality fluctuations, reduces the overall repair rate and maintenance cost of the equipment, and enhances the durability and performance stability of the equipment. In addition, an avoidance hole is opened at one end of the filter support seat 123 facing away from the installation opening 1232. The avoidance hole is used for the filter element to communicate with the waterway board 60. The existence of the avoidance hole optimizes the connection structure between the filter element and the waterway board 60. Compared with complex or indirect connection methods, it reduces possible fault points such as connection looseness and water leakage, making the connection between the filter element and the waterway board 60 tighter and more stable.

[0093] It should be noted that when the filter system 50 includes a primary filter element 51 and a secondary filter element 52, the two corresponding installation cavities 1231 on the filter support seat 123 further optimize the installation and management of the filter element. This design allows filter elements with different functions to be installed and operated in their own independent and adapted spaces, avoiding possible mutual interference and influence between different filter elements, ensuring that each filter element can give full play to its due filtering performance, and improving the filtering accuracy and efficiency of the entire filter system 50.

[0094] Furthermore, the waterway plate support seat 122 includes a seat body 1221 and a limit plate 1222, the seat body 1221 is connected to the installation surface, the limit plate 1222 is connected to the side of the seat body 1221 away from the installation surface, the waterway plate 60 is detachably connected to the seat body 1221, and the surface of the waterway plate 60 facing the hot tank assembly 20 is in contact with the limit plate 1222. Among them, the feature that the waterway plate 60 is detachably connected to the seat body 1221 greatly optimizes the maintenance and repair process of the equipment. When the waterway plate 60 is blocked, leaking or other faults occur, maintenance personnel can quickly and conveniently remove it from the seat body 1221 and conduct targeted inspection, cleaning or component replacement operations without complex disassembly of the entire equipment, which not only significantly shortens the maintenance time, but also reduces the downtime. Secondly, the existence of the limit plate 1222 can accurately control the safe distance between the waterway plate 60 and the hot tank assembly 20, and prevent the waterway plate 60 from being too close to the hot tank assembly 20 due to various factors after installation. The effective constraint of the position of the waterway plate 60 by the limit plate 1222 ensures that the normal temperature water can maintain a stable and suitable temperature state in the waterway, so that the various physical and chemical properties of the water can be maintained at a normal level, thereby ensuring that the subsequent filtration, purification and other links can be carried out according to the expected standards and effects, and improving the quality and stability of purified water.

[0095] Reference Figure 3 and Figure 4 Optionally, the middle shell 12 also includes a support member 126, which is connected to the filter support seat 123 and the enclosure 124. The heat and air purifier 1 also includes a control panel 80, which is fixed to the side of the support member 126 away from the mounting surface, and the control panel 80 is electrically connected to the hot tank assembly 20. From the perspective of the overall layout and stability of the equipment, the support member 126, as a key component connecting the filter support seat 123 and the enclosure 124, enhances the integrity and rigidity of the internal structure of the middle shell 12. It can effectively disperse and withstand various stresses generated during the operation of the equipment. Whether it is the force caused by water flow impact, thermal expansion and contraction or external vibration, it can be reasonably distributed and buffered through the support member 126, thereby ensuring that the relative positions of the filter support seat 123, the enclosure 124 and other internal components are stable and unchanged.

[0096] In terms of the operating environment and safety of the control board 80, fixing it on the side of the support member 126 away from the mounting surface and electrically connecting it to the hot water tank assembly 20 has obvious advantages. On the one hand, this position is far from the possible water sources and humid environments, reducing the risk of short circuits, damage or malfunctions of the control board 80 caused by water vapor erosion, ensuring the stable and reliable electrical performance of the control board 80, and ensuring that it can accurately monitor and control the heating process, temperature regulation and the realization of other related functions of the hot water tank assembly 20. On the other hand, the close electrical connection with the hot water tank assembly 20 enables the control board 80 to obtain the working state information of the hot water tank assembly 20 in real time and accurately, and make corresponding adjustments and feedback in a timely manner, optimizing the heating efficiency and energy utilization rate of the hot water tank assembly 20, avoiding situations such as overheating or underheating, ensuring that users can obtain hot water at an appropriate temperature at any time, and saving energy consumption. Considering the convenience of equipment maintenance and upgrade, this structural design provides great convenience for subsequent operations. When it is necessary to inspect, repair or upgrade the control board 80, maintenance personnel can relatively easily reach the position of the control board 80 on the support member 126 through a reasonable disassembly path, without having to perform large-scale disassembly and complex operations on the entire equipment, saving maintenance time and labor costs, and improving the maintainability and upgradability of the equipment.

[0097] Furthermore, the integrated water purification and heating machine 1 further includes a water leakage probe 90A. The water leakage probe 90A is connected to the support member 126 and abuts against the bottom surface in the height direction of the outer shell 10A. In terms of the accuracy and timeliness of water leakage detection, the water leakage probe 90A in this position can efficiently monitor the possible water leakage at the bottom of the integrated water purification and heating machine 1. Since water tends to accumulate at the bottom of the equipment under the action of gravity, the water leakage probe 90A directly abuts against the bottom surface of the outer shell 10A. Once there is a very small amount of water leakage, it can quickly sense and transmit a signal to the control system, triggering a corresponding alarm mechanism or taking emergency protection measures, such as cutting off the power supply and stopping the water circuit operation. This accurate and rapid water leakage detection ability greatly reduces the risk of short circuits, electrical failures of the integrated water purification and heating machine 1 and damage to the surrounding environment caused by the failure to detect water leakage in a timely manner, effectively protecting the internal precision components of the integrated water purification and heating machine 1 and the safety of users during use.

[0098] The hot water tank assembly 20 will be described in detail below.

[0099] Please refer to Figures 8 to 10, the hot water tank assembly 20 may include a tank body 21 and a heating element 22. The tank body 21 has a heating cavity 21a which can be used to hold liquid; the heating element 22 is connected to the tank body 21 to heat the liquid in the heating cavity 21a. It can be understood that the heating element 22 can be installed on the outer wall surface or near the tank body 21 to transfer heat to the liquid in the heating cavity 21a by heat conduction, so that the liquid in the heating cavity 21a can be heated; or, the heating element 22 is installed in the heating cavity 21a and connected to the tank body 21. In this way, the heating element 22 can directly heat the liquid in the heating cavity 21a. The embodiments of the present application do not make specific limitations on this.

[0100] Among them, when the heating element 22 is located in the heating cavity 21a, the terminal 221 of the heating element 22 can penetrate through the tank body 21 so that the terminal 221 extends out of the outer wall surface of the tank body 21, facilitating the electrical connection between the control board 80 and the terminal 221, and thus facilitating the control board 80 to control the operation of the heating element 22 according to the set program, so as to realize the heating of the liquid in the heating cavity 21a.

[0101] Please refer to Figure 8 and Figure 10 , the hot water tank assembly 20 further includes an exhaust pipe 24. The exhaust pipe 24 is connected to the tank body 21 and communicates with the heating cavity 21a. It can be understood that when the heating element 22 works, it will heat the liquid in the heating cavity 21a, so that part of the water in the heating cavity 21a is converted into water vapor, resulting in an increase in the internal pressure of the heating cavity 21a. If the water vapor in the heating cavity 21a cannot be discharged in time, it may cause excessive internal pressure of the hot water tank assembly 20, leading to potential safety hazards such as rupture or leakage of the hot water tank assembly 20. Therefore, the embodiments of the present application provide an exhaust pipe 24 communicating with the heating cavity 21a. The exhaust pipe 24 can be used to discharge the water vapor generated during the heating of the liquid in the heating cavity 21a to ensure the safety of the use of the tank body 21. In addition, after the water vapor in the heating cavity 21a is discharged from the exhaust pipe 24, the air content in the heating cavity 21a can be reduced, so that the heat acts more concentratedly on the water molecules, thereby improving the heating efficiency of the tank body 21.

[0102] The material of the exhaust pipe 24 may include silica gel; that is, silica gel material is widely used in the exhaust pipe 24 of the water dispenser due to its excellent high temperature resistance, corrosion resistance and flexibility. It can not only withstand the impact of high temperature water vapor inside the tank body 21 and is not easily deformed or damaged, but also adapt to the complex structural layout inside the integrated water purifier and heater 1 to ensure tight connection and no air leakage. In addition, the silica gel material is non-toxic and odorless and meets the food safety standards.

[0103] The hot water tank assembly 20 further includes a condensate pipe 28 which has a condensate cavity 281 capable of holding cooling water, and a part of the exhaust pipe 24 passes through the condensate cavity 281 so that a part of the exhaust pipe 24 is located inside the condensate cavity 281. Thus, when the water vapor in the exhaust pipe 24 flows through the condensate cavity 281, it can be cooled and condensed by the cooling water. At this time, the water vapor flowing through the condensate cavity 281 will be condensed into water droplets, and under the action of gravity, the water droplets will flow back from the exhaust pipe 24 into the heating cavity 21a. That is to say, by extending a part of the exhaust pipe 24 into the condensate cavity 281 of the condensate pipe 28, the cooling water in the condensate cavity 281 can condense the water vapor flowing through the condensate cavity 281, so that the water vapor is condensed into water droplets. In this way, it is possible to prevent the water vapor from spraying out from the faucet 2, so as to prevent the user from being scalded by the high-temperature water vapor, and further improve the safety of using the integrated water purifier and water heater 1. Moreover, since the water vapor in the exhaust pipe 24 can be cooled and condensed by the cooling water when flowing through the condensate cavity 281, the water vapor will be condensed into water droplets, and under the action of gravity, the water droplets will flow back from the exhaust pipe 24 into the heating cavity 21a. In this way, it is possible to prevent the faucet 2 from dripping water, so as to reduce the waste of water source. The material of the condensate pipe 28 can include stainless steel, copper, aluminum, etc. The embodiments of the present application do not make specific limitations on the material of the condensate pipe 28.

[0104] In the embodiment of the present application, by arranging a part of the exhaust pipe 24 to pass through the condensate cavity 281 of the condensate pipe 28, in this way, when the water vapor in the exhaust pipe 24 flows through the condensate cavity 281, the water vapor will be cooled and condensed into water droplets by the cooling water in the condensate cavity 281. In this way, the water droplets will flow back into the heating cavity 21a under the action of gravity to prevent the faucet 2 from dripping water, and at the same time, it is possible to prevent the water vapor from coming out of the faucet 2 to avoid scalding the user with high-temperature water vapor. In this way, the safety of using the integrated water purifier and water heater 1 is improved.

[0105] It should be noted that the embodiments of the present application do not make specific limitations on the type of the heating element 22. Exemplarily, the heating element 22 can be an electric heating wire heating element 22, a positive temperature coefficient (PTC) ceramic sheet heating element 22, etc. The electric heating wire heating element 22 utilizes the thermal effect of current to convert electrical energy into heat energy to heat the liquid in the heating cavity 21a; the PTC ceramic sheet heating element 22 utilizes the constant temperature heating characteristic of the PTC thermistor to realize the heating of the liquid in the heating cavity 21a at a constant temperature.

[0106] Please refer to Figure 10 , in some embodiments, the condensate pipe 28 has a water inlet 282 and a water outlet 283. Both the water inlet 282 and the water outlet 283 are communicated with the condensate cavity 281, and the water inlet 282 is used for connecting cooling water.

[0107] Further, the hot water tank assembly 20 further includes a water inlet pipe 25. One end of the water inlet pipe 25 is connected to the tank body 21 and communicates with the heating chamber 21a. The other end of the water inlet pipe 25 is connected to the condensation pipe 28 and communicates with the water outlet 283. It can be understood that, in order to facilitate the injection of liquid into the heating chamber 21a, the hot water tank assembly 20 is also provided with a water inlet pipe 25 connected to the tank body 21. One end of the water inlet pipe 25 communicates with the heating chamber 21a, and the other end of the water inlet pipe 25 communicates with the water outlet 283. In this way, when the tank body 21 needs to be replenished with water, the cooling water enters the condensation chamber 281 from the water inlet 282, and then the cooling water flows into the heating chamber 21a from the water outlet 283 and via the water inlet pipe 25, so as to replenish the heating chamber 21a with water.

[0108] Furthermore, since the other end of the water inlet pipe 25 communicates with the water outlet 283, and the water outlet 283 communicates with the condensation chamber 281, after the heating chamber 21a is replenished with water, the control board 80 controls the heating element 22 to heat. After the heating element 22 heats the cooling water in the heating chamber 21a for a period of time, water vapor is generated in the heating chamber 21a. The water vapor is discharged from the exhaust pipe 24. And since a part of the exhaust pipe 24 is located in the condensation chamber 281 at this time, and the condensation chamber 281 is filled with cooling water at this time, it is convenient for the cooling water to condense the water vapor flowing through the condensation chamber 281 and in the exhaust pipe 24, so as to prevent the water vapor from spraying out from the faucet 2.

[0109] It should be noted that the cooling water remaining in the condensation chamber 281 last time will flow due to the flow, and when the heating chamber 21a is replenished with water next time, it will flow into the heating chamber 21a through the water outlet 283 and the water inlet pipe 25. In this way, the cooling water in the condensation chamber 281 is replaced, so as to ensure the persistence of the condensation effect of the condensation chamber 281.

[0110] In some embodiments, in the width direction of the condensation pipe 28, the water inlet 282 and the water outlet 283 are located on the same side or different sides of the condensation pipe 28, and in the height direction of the condensation pipe 28, the height of the water outlet 283 is higher than the height of the water inlet 282. It can be understood that in the height direction of the condensation pipe 28, the position of the water outlet 283 on the condensation pipe 28 needs to be higher than the position of the water inlet 282, so that part of the cooling water entering from the water inlet 282 can be retained in the condensation chamber 281, thus facilitating part of the exhaust pipe 24 to be immersed in the cooling water, thereby improving the condensation effect of the condensation pipe 28.

[0111] It should be noted that in the height direction of the condensation pipe 28, the height from the position of the water inlet 282 on the condensation pipe 28 to the position of the water outlet 283 is not specifically limited. And the width direction of the above-mentioned condensation pipe 28 is perpendicular to the height direction of the condensation pipe 28.

[0112] In other embodiments, in the height direction of the condenser 28, the water inlet 282 is disposed at the bottom of the condenser 28, and the water outlet 283 is disposed at the top of the condenser 28. It is understandable that the water inlet 282 can be disposed at the top of the condenser 28, and the water outlet 283 is disposed at the top of the condenser 28, so that more cooling water can be retained in the condensation chamber 281, so that part of the exhaust pipe 24 is immersed in the cooling water, thereby improving the condensation effect of the condenser 28.

[0113] See also Figures 11 - 13 In some embodiments, in the height direction of the hot tank assembly 20, the height of the water inlet pipe 25 is lower than the height of the exhaust pipe 24. It can be understood that, since part of the exhaust pipe 24 is arranged in the condensing chamber 281, and the other end of the water inlet pipe 25 is communicated with the water outlet 283, and the water outlet 283 is communicated with the condensing chamber 281, the height of the water inlet pipe 25 is set lower than the height of the exhaust pipe 24, so that the water inlet pipe 25 is closer to the tank body 21, so that on the one hand, the water replenishment efficiency of the heating chamber 21a can be improved, and on the other hand, the height of the other end of the water inlet pipe 25 is lower than the end of the exhaust pipe 24 away from the tank body 21, so that when the condensing chamber 281 is filled with cooling water, the cooling water in the condensing chamber 281 will only flow into the water inlet pipe 25 from the water outlet 283, and will not flow into from the end of the exhaust pipe 24 away from the tank body 21, so as to prevent the cooling water in the condensing chamber 281 from flowing into the heating chamber 21a from the exhaust pipe 24.

[0114] It should be noted that the height direction of the above-mentioned hot tank assembly 20 can be understood as the height direction of the condenser 28.

[0115] See also Figure 10 as well as Figure 12 In some embodiments, the condenser 28 includes a condenser section 284, and the condenser section 284 has a first condenser opening 2841 and a second condenser opening 2842. It is understood that a condenser chamber 281 may be formed inside the condenser section 284, and the condenser chamber 281 is in communication with both the first condenser opening 2841 and the second condenser opening 2842, so that the exhaust pipe 24 passes through the condenser chamber 281 from the first condenser opening 2841 and then passes through the second condenser opening 2842, so that part of the exhaust pipe 24 is located in the condenser chamber 281, so that the cooling water in the condenser chamber 281 can condense the water vapor in the exhaust pipe 24 passing through the condenser chamber 281.

[0116] Furthermore, after the condensation section 284 is partially penetrated through the exhaust pipe 24, the exhaust pipe 24 and the first condensation opening 2841 and the second condensation opening 2842 need to be sealed. On the one hand, this can achieve water vapor separation, and on the other hand, it can prevent the cooling water in the condensation chamber 281 from flowing out of the condensation pipe 28 from the first condensation opening 2841 or the second condensation opening 2842.

[0117] Please continue to refer to Figure 10 and Figure 12 , further, in some embodiments, the condensing pipe 28 further includes a support pipe section 285. One end of the support pipe section 285 is connected to the end of the condensing section 284 close to the tank body 21. The support pipe section 285 communicates with the first condensing opening 2841 so that the exhaust pipe 24 passes through the support pipe section 285 and extends into the condensing cavity 281; and one end of the support pipe section 285 abuts against the tank body 21 to facilitate the support of the condensing section 284.

[0118] Please continue to refer to Figure 10 and Figure 12 , furthermore, in some embodiments, the condensing pipe 28 further includes an air outlet pipe section 286. One end of the air outlet pipe section 286 is connected to the end of the condensing section 284 away from the tank body 21. The other end of the air outlet pipe section 286 is connected to the faucet 2. The air outlet pipe section 286 communicates with the second condensing opening 2842 so that the end of the exhaust pipe 24 away from the tank body 21 extends into the air outlet pipe section 286 through the second condensing opening 2842, thereby realizing that a part of the exhaust pipe 24 extends into the air outlet pipe section 286.

[0119] It should be noted that the embodiments of the present application do not specifically limit the connection manners of the condensing section 284, the support pipe section 285, and the air outlet pipe section 286.

[0120] Please continue to refer to Figure 10 and Figure 12 , exemplarily, the condensing section 284, the support pipe section 285, and the air outlet pipe section 286 are integral components; that is, the condensing section 284, the support pipe section 285, and the air outlet pipe section 286 can be integrally formed by one injection molding. In this way, on the one hand, it is convenient for a part of the exhaust pipe 24 to extend into the condensing pipe 28, and on the other hand, it can improve the connection stability and sealing performance of the condensing section 284, the support pipe section 285, and the air outlet pipe section 286 to prevent the cooling water in the condensing cavity 281 from flowing out of the condensing pipe 28.

[0121] Exemplarily, the condensing section 284, the support pipe section 285, and the air outlet pipe section 286 are all connected by welding to realize the connection between the end of the condensing section 284 close to the tank body 21 and the support pipe section 285, and the connection between the end of the condensing section 284 away from the tank body 21 and the air outlet pipe section 286.

[0122] After a part of the exhaust pipe 24 extends into the outlet pipe section 286, in order to achieve the sealed connection of both the support pipe section 285 and the outlet pipe section 286 with the part of the exhaust pipe 24, therefore, in some embodiments, both the support pipe section 285 and the outlet pipe section 286 are in close fit with the exhaust pipe 24; that is, the inner diameters of both the support pipe section 285 and the outlet pipe section 286 are equal to the outer diameter of the exhaust pipe 24, so that the outer wall of the exhaust pipe 24 is in sealed fit with the inner walls of both the support pipe section 285 and the outlet pipe section 286, thereby improving the sealing performance of the connection between the exhaust pipe 24 and the support pipe section 285 and the outlet pipe section 286. In this way, it is possible to prevent the cooling water in the condensation chamber 281 from flowing out of the condensation pipe 28, and to achieve water-vapor separation. Of course, in some other embodiments, the support pipe section 285 and the outlet pipe section 286 can be sealedly connected to the part of the exhaust pipe 24 through a silica gel seal.

[0123] Please refer to Figure 14 , in some embodiments, the tank body 21 includes a tank body 211, a tank top cover 212, and a tank bottom cover 213.

[0124] Specifically, the material of the tank body 21 is usually made of food-grade stainless steel to ensure the safety and hygiene of the liquid. These materials have the characteristics of stable structure, high temperature resistance, and not easy to rust, so as to meet the use requirements of the tank body 21. The tank top cover 212 is connected to the top of the tank body 211, and the tank bottom cover 213 is connected to the bottom of the tank body 211; that is, the tank top cover 212, the tank body 211, and the tank bottom cover 213 can be connected by welding, screwing, etc. to achieve the sealed connection of the tank top cover 212, the tank body 211, and the tank bottom cover 213, and the tank bottom cover 213, the tank body 211, and the tank top cover 212 enclose a heating chamber 21a to ensure the sealing performance of the heating chamber 21a.

[0125] Furthermore, due to the effect of heat convection, the water vapor generated in the heating chamber 21a during the heating process will naturally rise, and in the embodiment of the present application, the exhaust pipe 24 is arranged on the tank top cover 212; that is, the tank top cover 212 is provided with a first through hole 2121, the exhaust pipe 24 is connected to the tank top cover 212, and another part of the exhaust pipe 24 extends into the heating chamber 21a through the first through hole 2121, so that the exhaust pipe 24 is communicated with the heating chamber 21a, facilitating the discharge of the water vapor generated in the heating chamber 21a during the heating process from the exhaust pipe 24.

[0126] Moreover, arranging the exhaust pipe 24 on the tank top cover 212 can prevent the liquid in the heating chamber 21a from flowing back; that is, if the exhaust pipe 24 is arranged at the bottom of the hot tank, when the external pressure (the water pressure of water replenishment) is greater than the pressure in the heating chamber 21a, water may flow back into the heating chamber 21a through the exhaust pipe 24, causing pollution and damage to the heating chamber 21a.

[0127] Please continue to refer to Figure 14 , in some embodiments, to ensure the normal operation of the hot tank assembly 20 and the safe heating of the liquid in the heating chamber 21a, the hot tank assembly 20 further includes a detection assembly 23, and the detection assembly 23 includes a water level detection element 232, a water quality detection element, and a temperature control element 237.

[0128] Specifically, the water level detection element 232 is connected to the tank body 21, and the water level detection element 232 communicates with the heating chamber 21a, so that the water level detection element 232 can detect the water level in the heating chamber 21a. And the type of the water level detection element 232 in the embodiments of the present application is not specifically limited. Exemplarily, the water level detection element 232 can be one of a float type water level sensor, an electrode type water level sensor, and a capacitance type water level sensor. Among them, the float type water level sensor detects the change of the water level by the up and down floating of the float. When the water level rises, the float also rises; when the water level drops, the float drops, and the floating of the float will trigger a switch inside the float type water level sensor, thereby outputting a corresponding electrical signal to the control board 80 to facilitate detecting the water level in the heating chamber 21a. The electrode type water level sensor detects the water level by arranging electrodes in the heating chamber 21a and utilizing the conductivity of water. When the water level rises and contacts the electrode, the circuit will be turned on, thereby outputting an electrical signal to the control board 80 to facilitate detecting the water level in the heating chamber 21a. The capacitance type water level sensor detects the water level by measuring the capacitance value formed between the capacitance type water level sensor and the water level. When the water level rises, the capacitance value will change, thereby outputting a corresponding electrical signal to the control board 80 to facilitate detecting the water level in the heating chamber 21a.

[0129] Please continue to refer to Figure 13 , further, in some embodiments, the water level detection element 232 includes a high water level probe 233 and a low water level probe 234. It can be understood that the high water level probe 233 is used to detect the position of the highest water level in the heating chamber 21a, and the low water level probe 234 is used to detect the position of the lowest water level in the heating chamber 21a; that is, when the liquid in the heating chamber 21a rises to the highest water level, the water inlet pipe 25 stops supplying water to the heating chamber 21a to prevent the liquid in the heating chamber 21a from overflowing; when the liquid in the heating chamber 21a drops to the lowest water level, the water inlet pipe 25 supplies water to the heating chamber 21a to prevent the heating chamber 21a from dry burning.

[0130] It should be noted that the positions of the high water level probe 233 and the low water level probe 234 arranged on the tank body 21 in the embodiments of the present application are not specifically limited.

[0131] Please continue to refer to Figure 14, in another embodiment, the water level detection element 232 may include two high water level probes 233 and one low water level probe 234. Among them, the two high water level probes 233 may be arranged on the tank top cover 212, and the positions of the high water levels detected by the two high water level probes 233 are inconsistent; that is, there are a position of the first high water level and a position of the second high water level in the heating cavity 21a, and in the height direction of the tank body 21, the position of the first high water level is higher than the position of the second high water level. At this time, one high water level probe 233 is used to detect the position of the first high water level, and the other high water level probe 233 is used to detect the position of the second high water level. When the other high water level probe 233 fails, the detection can still be carried out through one high water level probe 233 to improve the accuracy of the detection by the high water level probe 233. Moreover, the low water level probe 234 may be arranged on the tank top cover 212 or on the tank bottom cover 213 to detect the position of the lowest water level in the heating cavity 21a.

[0132] The water quality detection element is connected to the tank body 21 and communicates with the heating cavity 21a; that is, the water quality detection element is used to detect the quality of the liquid in the heating cavity 21a to ensure that safe and hygienic liquid is provided to the user. The type of the water quality detection element in the embodiments of the present application is not specifically limited. Exemplarily, the water quality detection element may be an electrochemical sensor, a biosensor, etc.

[0133] The temperature control element 237 is connected to the tank body 21 and communicates with the heating cavity 21a; that is, a part of the temperature control element 237 extends into the heating cavity 21a so as to facilitate the temperature control element 237 to detect the temperature of the liquid in the heating cavity 21a. Among them, the temperature control element 237 may be arranged on the tank top cover 212 or on the tank body 211, and the embodiments of the present application do not specifically limit this.

[0134] Please continue to refer to Figure 14 , further, in some embodiments, the temperature control element 237 includes a temperature control fixing plate 2371 and a temperature sensor 2372. Specifically, the temperature control fixing plate 2371 is connected to the tank body 21; that is, when the temperature control element 237 is installed on the tank body 211, the temperature control fixing plate 2371 can be fixed on the tank body 211, or the tank top cover 212, or the tank bottom cover 213 by welding, screwing, clamping, bonding, etc. A second through hole 2373 communicating with the heating cavity 21a is provided on the temperature control fixing plate 2371, so that it is convenient for the temperature sensor 2372 to extend into the heating cavity 21a through the second through hole 2373, so that the temperature sensor 2372 can detect the temperature of the liquid in the heating cavity 21a. When the temperature of the liquid is too high, the control board 80 can control the heating element 22 to stop heating to protect the tank body 21.
