[0047] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0048] It should be understood that the terms used herein are for the purpose of describing specific example embodiments only and are not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "one", "an" and "said" as used herein may also be meant to include plural forms. The terms "comprise", "include", "contain" and "have" are inclusive and therefore specify the presence of stated features, steps, operations, elements and / or parts, but do not exclude the presence or addition of one or more other features, steps, operations, elements, parts, and / or combinations thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring them to be performed in the specific order described or illustrated, unless the order of execution is clearly indicated. It should also be understood that additional or alternative steps may be used.

[0049] Although the terms first, second, third, etc. can be used in the text to describe multiple elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms can only be used to distinguish an element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates otherwise, terms such as "first", "second" and other numerical terms do not imply order or sequence when used in the text. Therefore, the first element, component, region, layer or section discussed below can be referred to as the second element, component, region, layer or section without departing from the teaching of the example embodiments.

[0050] In this application, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0051] For ease of description, spatially relative terms may be used herein to describe the relationship of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," and the like.

For example, if the device in the figures is rotated, an element described as "below" or "beneath" another element or feature would subsequently be oriented "above" or "above" the other element or feature. Thus, the example term "below" can encompass both above and below orientations.

[0052] The utility model proposes a water supply device 1, please combine Figure 1 、 Figure 2 and Figure 3 As shown, the water supply equipment 1 includes a box body 10, a filter assembly 30 and a first water tank 20 arranged in the box body 10, and a water storage cup 41 arranged outside the box body 10. The water storage cup 41 is placed above the water receiving box 70. The first water tank 20 is respectively connected to the filter assembly 30 and the water storage cup 41. The first water tank 20 is used to store pure water filtered by the filter assembly 30 and supply pure water to the water storage cup 41.

[0053] The water supply device proposed in the present invention can use the first water tank 20 to store pure water filtered by the filter assembly 30, and use the first water tank 20 to supply water to multiple water storage cups 41 provided outside the box body 10. Even if the user removes the water storage cups 41, the water supply device 1 can still use the first water tank 20 to supply pure water to external water-using devices, without affecting the continued use of the water supply device 1.

[0054] The water supply device 1 also includes a second water tank 12, which is used to connect to a water source or store raw water. The second water tank 12 supplies raw water to the filter assembly 30. The filter assembly 30 includes a pre-filter element (not shown), a reverse osmosis filter element (not shown), and a post-filter element (not shown). The pre-filter element can be made of various forms of PP, various forms of activated carbon, ultrafiltration, or nanofiltration. The raw water in the second water tank 12 first enters the pre-filter element, undergoes coarse filtration by the pre-filter element, and then enters the reverse osmosis filter element. After filtration by the reverse osmosis filter element, the raw water is divided into one path of pure water and one path of wastewater. The wastewater flows from the reverse osmosis wastewater outlet into the wastewater waterway channel, and finally the wastewater flows back into the second water tank 12. The pure water flows into the post-filter element and, after being filtered by the post-filter element, flows into the first water tank 20 for drinking.

[0055] The post-filter element can be made of various activated carbon forms, and the post-filter and pre-filter elements can be separate elements or a single composite element. A composite filter element combines the filtering functions of both pre- and post-filter elements, with two independent flow paths within the composite filter element. One path is used for coarse filtration, equivalent to the pre-filter element. Raw water enters the reverse osmosis filter element after coarse filtration through this path. The other path is used for secondary filtration, equivalent to the post-filter element. Purified water filtered by the reverse osmosis filter element passes through this path for a second filtration, ultimately exiting the composite filter element's outlet.

[0056] Specifically, pure water filtered by the filter assembly 30 is output to the first water tank 20 for storage. The first water tank 20 also supplies pure water to a water storage cup 41, which is located outside the housing 10. This allows the user to readily access the water stored in the water storage cup 41, satisfying their need for large quantities of pure water. If a user removes the water storage cup 41 due to a need for large quantities of pure water, the water supply device 1 can still utilize the first water tank 20 to store pure water and supply it to external water-using devices, without affecting the continued use of the water supply device 1.

[0057] The first water tank 20 can supply water to the water storage cup 41 by active pumping, for example, by providing a water pump on the pipeline connecting the first water tank 20 and the water storage cup 41, so that the water pump pumps the water in the first water tank 20 into the water storage cup 41. Alternatively, the first water tank 20 can supply water to the water storage cup 41 by passive delivery, for example, by providing a pipeline connecting the first water tank 20 and the water storage cup 41 near the bottoms of both, so that the first water tank 20, the water storage cup 41, and the pipeline connecting the two together form a communicating vessel structure, thereby allowing the pure water in the first water tank 20 to automatically flow into the water storage cup 41.

[0058] In some embodiments of the present invention, please combine Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, the first water tank 20 is provided with a first water outlet 212, and the water storage cup 41 is provided with a first plug-in port 412. The first water tank 20 is used to store pure water filtered by the filter assembly 30. The water supply device 1 also includes a water supply connector 23, which is mounted on the first water tank 20 and communicates with the first water outlet 212. The water supply connector 23 is removably plugged into the first plug-in port 412, connecting the first water tank 20 and the water storage cup 41. Using the plug-in connection between the water supply connector 23 and the first plug-in port 412, the user simply aligns the water supply connector 23 with the first plug-in port 412 and gently pushes it in to complete the connection, facilitating access to the water storage cup 41. The first water outlet 212 is located near the bottom of the water tank, and the first plug-in port 412 is located near the bottom of the water storage cup 41. Together, the first water tank 20, the water supply connector 23, and the water storage cup 41 form a communicating vessel structure. According to the communicating vessel principle, when the same liquid is not flowing, the liquid levels in each container are level. Therefore, when the water level in the first water tank 20 is higher than the water level in the water cup 41, under the action of gravity, the pure water in the first water tank 20 will automatically flow to the water cup 41 until the water levels of the two are equal. Conversely, when the water level in the water cup 41 is higher than the water level in the first water tank 20, the pure water in the water cup 41 will also automatically flow to the first water tank 20 to maintain water level balance. The communicating vessel structure allows the pure water in the first water tank 20 to flow automatically into the water cup 41 without the need for additional power equipment, saving energy. The user can achieve automatic water storage in the water cup 41 without manual operation, which improves the convenience of use. In addition, the communicating vessel structure can ensure that the water levels in the first water tank 20 and the water cup 41 are always maintained at similar heights, making it convenient for the user to observe and understand the water level. The communicating vessel structure is simple and reliable in design, does not require complex control devices and piping systems, and reduces the cost and failure rate of the equipment.

[0059] In detail, please combine Figure 3 、 Figure 4 and Figure 5As shown, the water supply connector 23 includes a connected main body 231, a first plug portion 232, and a second plug portion 233. The first plug portion 232 extends in a first direction and plugs into the first plug port 412. The second plug portion 233 plugs into the first water outlet 212. The first plug portion 232 is configured as a cylindrical plug with a smooth outer surface to ensure smooth insertion and removal. The first plug port 412 of the water storage cup 41 is configured as a cylindrical receptacle with an inner diameter slightly larger than the outer diameter of the water supply connector 23. The precise fit between the two dimensions ensures a tight and stable connection. A rubber sealing ring is installed inside the first plug port 412 as a seal. Rubber has excellent elasticity and sealing properties, and can adapt to various temperature and pressure fluctuations. When the water supply connector 23 is inserted into the first plug port 412, the rubber sealing ring is placed around the outside of the water supply connector 23, squeezed and deformed, and fills the gap between the water supply connector 23 and the first plug port 412, forming a seal.

[0060] In this embodiment, the first direction is parallel to the horizontal direction, meaning that the water cup 41 and the water supply connector 23 are connected in the horizontal direction. When placing the water cup 41, the user can first place the water cup 41 on the water receiving box 70, then move the water cup 41 horizontally to insert the first plug portion 232 into the first plug port 412, making the placement of the water cup 41 more labor-efficient. In some embodiments, due to manufacturing and assembly tolerances of components, when the water supply device 1 is placed on a horizontal surface, the extension direction of the first plug portion 232 (i.e., the first direction) may also form a relatively small angle with the horizontal surface.

[0061] In some embodiments of the present invention, please combine Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10As shown, the first water tank 20 includes a first shell 21 and a water supply installation portion 210 provided on the first shell 21. The interior of the first shell 21 defines a first water storage chamber 201 for storing pure water. The water supply installation portion 210 includes a first tube body portion 215 communicating with the first water storage chamber 201 and a second tube body portion 216 communicating with the first tube body portion 215. The first tube body portion 215 and the second tube body portion 216 are both tubular. The interiors of the first tube body portion 215 and the second tube body portion 216 are hollow and form a channel for pure water to flow. The outer contours of the first tube body portion 215 and the second tube body portion 216 and the contours of their inner cavities can be set to cylindrical, prismatic or irregular shapes, etc. The first tube body portion 215 and the second tube body portion 216 are arranged perpendicular to each other, the first tube body portion 215 extends along the first direction (i.e., the horizontal direction), and the second tube body portion 216 extends along the second direction (i.e., the vertical direction). The top of the second tube body portion 216 defines the first water outlet 212, and the second plug-in portion 233 is arranged as a circular tubular structure extending along the second direction. The second plug-in portion 233 is inserted into the second tube body portion 216 from top to bottom, so that the water supply connector 23 is connected to the first water outlet 212.

[0062] It should be noted that the water supply connector 23 and the first water tank 20 are arranged in a plug-in connection manner. After the first water tank 20 is fixedly installed to the box body 10, the relative position of the first plug-in portion 232 in the vertical direction to the first water tank 20 and the water storage cup 41 is adjusted by adjusting the axial position of the second plug-in portion 233 in the second tube body portion 216, so that the first plug-in portion 232 can be aligned with the first plug interface 412 of the water storage cup 41, thereby overcoming the problem that the first plug-in portion 232 cannot be aligned with the first plug interface 412 due to factors such as assembly errors.

[0063] In some embodiments of the present invention, please combine Figure 3 、 Figure 10 、 Figure 11 、 Figure 12 and Figure 13As shown, the water supply device 1 also includes a first sealing member 2161. The first sealing member 2161 comprises a tubular sealing inner sleeve 21611, a sealing outer sleeve 21612 that is sleeved over the sealing inner sleeve 21611, and a sealing connection portion 21613 connecting the sealing inner sleeve 21611 and the sealing outer sleeve 21612. The outer diameter of the sealing inner sleeve 21611 matches the inner diameter of the second tubular portion 216, allowing it to be tightly inserted into the second tubular portion 216. The sealing inner sleeve 21611 is made of a material with a certain degree of elasticity and flexibility, such as rubber or silicone, to ensure a good seal with the second tubular portion 216. The sealing outer sleeve 21612 is sleeved over the second tubular portion 216. The inner diameter of the sealing outer sleeve 21612 is greater than the outer diameter of the second tubular portion 216. A gap space is defined between the sealing inner sleeve 21611 and the sealing outer sleeve 21612 to accommodate the second tubular portion 216. The sealing outer sleeve 21612 and the sealing inner sleeve 21611 may be made of the same or different materials. If the sealing outer sleeve 21612 and the sealing inner sleeve 21611 are made of different materials, the sealing outer sleeve 21612 may be made of a relatively hard material, such as plastic or metal, to protect and secure the sealing inner sleeve 21611. The sealing connection portion 21613 connects the sealing inner sleeve 21611 and the sealing outer sleeve 21612, ensuring a secure and reliable connection between the two. The sealing connection portion 21613 may be an annular structure or may have multiple connection points, the specific form of which depends on the design and usage requirements of the seal.

[0064] Please combine Figure 3 、 Figure 5 and Figure 13 As shown, the sealing inner sleeve 21611 is inserted into the second tube portion 216. Due to its elasticity, the sealing inner sleeve 21611 deforms slightly during insertion, fitting tightly against the inner wall of the second tube portion 216, forming a first seal. The second plug-in portion 233 is inserted into the sealing inner sleeve 21611. The outer diameter of the second plug-in portion 233 matches the inner diameter of the sealing inner sleeve 21611, allowing it to fit tightly inside. After the second plug-in portion 233 is inserted into the sealing inner sleeve 21611, the sealing inner sleeve 21611 further deforms, forming a second seal with the second plug-in portion 233. The sealing inner sleeve 21611 cooperates with the inner wall of the second tube portion 216 and the outer circumference of the second plug-in portion 233, respectively, to seal the first water outlet 212, preventing water leakage from the first water tank 20 at the first water outlet 212.

[0065] Furthermore, please combine Figure 3 、 Figure 5 and Figure 13As shown, the inner wall of the sealing inner sleeve 21611 is provided with at least one annular protrusion 216111 extending along the circumference of the sealing inner sleeve 21611. The annular protrusion 216111 can increase the contact area of ​​the seal and improve the sealing pressure, thereby effectively preventing pure water leakage.

[0066] Furthermore, please combine Figure 3 、 Figure 5 and Figure 13 As shown, the inner wall of the sealing inner sleeve 21611, facing the water supply connector 23, is provided with a first guide structure 218 with a gradually expanding inner diameter. Specifically, the first guide structure 218 has a conical shape with a gradually expanding inner diameter. Starting from the end of the sealing inner sleeve 21611, the inner diameter gradually decreases to equal the inner diameter of the sealing inner sleeve 21611, forming a smooth transition slope. The inclination angle of the transition slope relative to the axis of the sealing inner sleeve 21611 can be adjusted according to actual needs and can take any value between 15° and 45°, for example, 15°, 20°, 30°, 40°, 45°, etc.

[0067] By providing the first guide structure 218, the gradually expanding inner diameter of the first guide structure 218 provides guidance for the water supply connector 23 as the second plug-in portion 233 is inserted into the sealing inner sleeve 21611. The end of the water supply connector 23 first contacts the wider portion of the first guide structure 218. Then, as the inner diameter gradually decreases during insertion, it easily slides into the sealing inner sleeve 21611. This design significantly reduces the difficulty of insertion and improves operational convenience. Furthermore, the first guide structure 218 guides the water supply connector 23 at the correct angle for insertion, extending the service life of the sealing inner sleeve 21611 and the water supply connector 23. Due to the gradually expanding inner diameter of the first guide structure 218, the deformation of the sealing inner sleeve 21611 during insertion of the second plug-in portion 233 is more uniform, helping to improve the stability of the seal.

[0068] In other embodiments, the first guide structure 218 can also be designed to have an arc-shaped transition with a gradually expanding inner diameter. For example, a circular arc curve or a parabolic curve can be used to achieve a gradually increasing inner diameter. This design can make the water supply connector 23 smoother during insertion, reducing jamming and resistance.

[0069] In some embodiments of the present invention, Figure 6 and Figure 9As shown, the first water tank 20 also includes a first water inlet 211 and a first air outlet 213. The first water inlet 211 is connected to the filter assembly 30. Pure water filtered by the filter assembly 30 flows into the first water tank 20 through the first water inlet 211. The first water inlet 211 is located at the bottom of the first water tank 20. The first water inlet 211 and the first water outlet 212 are located on opposite sides of the first water tank 20, respectively, forming a bottom-inlet and bottom-outlet structure of the first water tank 20, allowing water to form a relatively smooth flow path within the first water tank 20. New water flows in from the first water inlet 211 at the bottom, pushing the existing water in the first water tank 20 toward the water outlet, thereby minimizing the formation of dead water areas and ensuring that the water in the water tank is fully circulated and refreshed, thereby achieving continuous water circulation, helping to maintain the freshness of the water and preventing the water from remaining in the first water tank 20 for a long time, thereby generating odor or breeding bacteria.

[0070] like Figure 6 As shown, the first exhaust port 213 is located at the top of the first water tank 20. When pure water enters the first water tank 20 through the first water inlet 211, it squeezes the air originally inside the first water tank 20 toward the top. Without the exhaust port, this air would form an air blockage within the water tank, hindering the normal flow of water. The first exhaust port 213 located at the top allows the air inside the water tank to be discharged in a timely manner, ensuring that water can flow smoothly from the first water inlet 211 and out of the first water outlet 212, thus ensuring the normal operation of the first water tank 20.

[0071] Furthermore, during the filling and draining process of the first water tank 20, the pressure inside the first water tank 20 will change. The first vent 213 allows the first water tank 20 to communicate with the outside atmosphere, thereby maintaining the pressure inside the first water tank 20 in equilibrium with the outside atmospheric pressure. This helps prevent the first water tank 20 from deforming, rupturing, or damaging connected pipes and equipment due to excessive pressure differences.

[0072] It should also be noted that if the air in the first water tank 20 is not promptly exhausted, it may create conditions for the growth of microorganisms. Microorganisms thrive in a moist, warm, and airy environment, thereby contaminating the water in the tank. The first exhaust port 213 exhausts the air in the first water tank 20, reducing the possibility of microbial growth and ensuring the hygienic safety of the pure water.

[0073] In some embodiments of the present invention, Figure 7 and Figure 9As shown, the inner wall of the first water tank 20 is provided with a plurality of first reinforcing ribs 214. The length of the first reinforcing ribs 214 extends vertically. The plurality of first reinforcing ribs 214 distributed along the inner wall of the first water tank 20 effectively increases the rigidity and strength of the first water tank 20. When the first water tank 20 is filled with water or subjected to external pressure, the first reinforcing ribs 214 can partially absorb the pressure, preventing the first water tank 20 from deforming or rupturing. In particular, along the height of the first water tank 20, the presence of the first reinforcing ribs 214 can resist the longitudinal stress generated by the gravity and pressure of the water, thereby improving the overall stability of the first water tank 20.

[0074] Furthermore, the height of the first reinforcing ribs 214 protruding from the inner wall of the first water tank 20 increases gradually from top to bottom. This arrangement can guide the water flow within the first water tank 20. When pure water enters the water tank, the higher first reinforcing ribs 214 provide less obstruction to the water flow, allowing the water to flow more smoothly. As the water level drops, the lower, higher reinforcing ribs gradually guide the water flow, allowing the water to flow more evenly from the first water outlet 212. This prevents the water from forming vortices or localized stagnation within the first water tank 20, improves the fluidity and renewal rate of the water, and helps reduce the accumulation of impurities and sediment in the water at the bottom of the water tank.

[0075] In some embodiments of the present invention, please combine Figure 6 、 Figure 7 and Figure 8 As shown, the water supply device 1 also includes a liquid level detection component 22. The liquid level detection component 22 is disposed within the first water tank 20 and is used to detect the water level data within the first water tank 20. When the liquid level detection component 22 detects that the water level data within the first water tank 20 is lower than a first water level, it indicates that the water level in the first water tank 20 is insufficient, and the water supply device 1 needs to start water production to replenish the water to ensure sufficient pure water supply at all times. When the water level data is higher than a second water level, it indicates that the water level in the water tank is sufficient, and the water supply device 1 stops water production to prevent excessive water storage in the first water tank 20 and pure water overflow.

[0076] The first water level is a warning water level, indicating that the amount of water in the first water tank 20 is close to the minimum acceptable level. The setting of this water level needs to take into account the actual use needs and the water production capacity of the water supply equipment 1. In this embodiment, the total water storage height of the first water tank 20 is H, the height of the first water level is h1, and the value range of h1 / H is 0.15 to 0.20. For example, h1 / H can be 0.15, 0.16, 0.17, 0.18, 0.18, 0.20, etc. This setting makes the setting height of the first water level more appropriate, that is, it can start water production when the amount of pure water in the first water tank 20 is small, reducing the number of times the equipment operates and energy consumption. Moreover, when the water level in the first water tank 20 drops to the first water level, about one-fifth of the pure water is still stored in the first water tank 20, and pure water can still be supplied to the user, avoiding the situation of untimely water supply, thereby improving the user experience.

[0077] The height of the second water level is h2, and the value of h2 / H ranges from 0.75 to 0.90. For example, h1 / H can be 0.75, 0.80, 0.85, 0.90, etc., indicating that the second water level is higher than the first water level and is a safety upper limit. When the water level in the first water tank 20 reaches the second water level, the water supply device 1 stops producing water to prevent the water tank from overflowing or causing damage to the device.

[0078] The liquid level detection component 22 includes but is not limited to a pressure sensor, an ultrasonic detection device, a capacitive liquid level gauge, etc. For example, in some embodiments, a pressure sensor is installed at the bottom of the first water tank 20 to indirectly determine the water level by detecting the pressure of water on the bottom of the water tank. The pressure of water is proportional to the water level, and the water level data can be accurately calculated by measuring the pressure value. This detection method is applicable to water tanks of various shapes and sizes and has high accuracy and stability. In other embodiments, the liquid level detection component 22 is a capacitive liquid level gauge, which includes two electrodes, which are respectively installed at the first water level and the second water level position in the water tank. When the water level changes, the dielectric constant of water will change the capacitance value between the electrodes. The water level can be determined by measuring the change in capacitance value.

[0079] In this embodiment, the liquid level detection assembly 22 includes a float, a sensor, and a slide rod 227. The float is typically made of a material with a density less than that of water, such as plastic or foam. The float can be spherical, cylindrical, or other shapes suitable for floating in water. The float slides up and down on the slide rod 227 as the water level in the first water tank 20 changes. The change in the float's position reflects the water level in the tank.

[0080] The slide bar 227 is mounted vertically within the first water tank 20 and is made of a sturdy material, such as stainless steel or aluminum alloy, to ensure stability within the water tank. The slide bar 227 provides guidance and support for the float, allowing the float to slide accurately up and down along the slide bar 227 under the action of buoyancy.

[0081] A sensor, including but not limited to a photoelectric sensor, a Hall effect sensor, and a capacitive sensor, is fixed to the slide bar 227. The sensor is used to detect the position of the float and convert it into corresponding water level data. The sensor has high precision, high reliability, and fast response characteristics, accurately reflecting changes in the water level in the first water tank 20.

[0082] In an exemplary embodiment, please combine Figure 6 、 Figure 7 and Figure 8 As shown, the sensor adopts a Hall sensor. Specifically, the float includes a first float 221 and a second float 222, the sensor includes a first Hall element (not shown in the figure) and a second Hall element (not shown in the figure), the slide bar 227 is fixed with a first baffle 223, a second baffle 224, a third baffle 225 and a fourth baffle 226 arranged in sequence, the first baffle 223 is arranged near the bottom of the first water tank 20, the fourth baffle 226 is arranged near the top of the first water tank 20, the second baffle 224 and the third baffle 225 are located between the first baffle 223 and the fourth baffle 226, and the height of the second baffle 224 in the first water tank 20 is equal to the first water level, the first Hall element is installed on the second baffle 224, the first float 221 is set Between the first baffle 223 and the second baffle 224, the first float 221 is provided with a first magnet (not shown in the figure) that cooperates with the first Hall element. The first float 221 floats up and down with the water level in the first water tank 20. When the water level reaches or exceeds the first water level, the first float 221 floats up and hits the second baffle 224. The first Hall element senses the first magnet and generates electrical signal data to determine that the current water level has reached the first water level. When the water level reaches or falls below the first water level, the first float 221 moves downward and separates from the second baffle 224. The distance between the first magnet and the first Hall element is too large, exceeding the sensing distance of the first Hall element, and generates electrical signal data indicating that the current water level is lower than the first water level.

[0083] The height of the fourth baffle 226 in the first water tank 20 is equal to the second water level. The second Hall element is installed on the fourth baffle 226. The second float 222 is arranged between the third baffle 225 and the fourth baffle 226. The second float 222 is provided with a second magnet (not shown in the figure) that cooperates with the second Hall element. The second float 222 floats up and down with the water level in the first water tank 20. When the water level reaches or exceeds the second water level, the second float 222 floats up and hits the fourth baffle 226. The second Hall element senses the second magnet and generates electrical signal data to determine that the current water level has reached the second water level. When the water level reaches or falls below the second water level, the second float 222 moves downward and separates from the fourth baffle 226. The distance between the second magnet and the second Hall element is too large, exceeding the sensing distance of the second Hall element. The second Hall element generates electrical signal data indicating that the current water level is lower than the second water level.

[0084] In this embodiment, Figure 7 、 Figure 8 and Figure 9 As shown, the first water tank 20 includes a first shell 21 and a top cover 25. The first shell 21 includes a bottom wall 2101 and a side wall 2102 connected to each other. The bottom wall 2101 is a flat plate structure. The side wall 2102 extends around the circumferential edge of the bottom wall 2101, and the bottom wall 2101 and the side wall 2102 are an integral structure. The bottom wall 2101 and the side wall 2102 can be connected to form an integral structure by a fusion connection, or the bottom wall 2101 and the side wall 2102 can also be integrally injection molded. The top cover 25 is mounted on the top of the side wall 2102, sealing the top opening. The top cover 25 is provided with a positioning hole 24, and the slide rod 227 is inserted into the positioning hole 24. Two limiting nuts are mounted on the slide rod 227, one of which is located inside the first water tank 20 and can abut against the inner wall of the top cover 25, while the other is located outside the first water tank 20 and can abut against the outer wall of the top cover 25. The two limiting nuts restrict the movement of the slide rod 227 relative to the top cover 25 along the axial direction of the slide rod 227. After the slide rod 227 and the top cover 25 are assembled, the slide rod 227 and the top cover 25 are installed as a whole on the top of the side wall 2102.

[0085] Among them, Figure 8 As shown, an annular sealing groove 251 is provided on the side of the top cover 25 facing the bottom wall 2101, and the contour of the annular sealing groove 251 matches the contour of the top of the side wall 2102.

[0086] Furthermore, if Figure 7 and Figure 9As shown, the bottom wall 2101 is provided with a limiting groove 217. Along the vertical direction, the projection of the positioning hole 24 on the bottom wall 2101 is located in the limiting groove 217. The slide rod 227 is passed through the positioning hole 24, and the end of the slide rod 227 facing the bottom wall 2101 is located in the limiting groove 217. With this arrangement, the positioning hole 24 and the limiting groove 217 can be used to limit the top and bottom of the slide rod 227 respectively, so that the slide rod 227 remains in a vertical state, thereby improving the detection accuracy of the liquid level detection component 22.

The internal space of the box body 10 is divided by setting the partition 101, and a first installation space for accommodating the first water tank 20 is separated between the second partition 1012 and the front panel 11, and a second installation space for installing the second water tank 12 is separated by the second partition 1012 and the third partition 1013. The first water tank 20 is arranged between the second partition 1012 and the front panel 11 and is respectively connected to the partition 101 and the front panel 11, thereby avoiding the water tank from shaking randomly in the box body 10, improving the stability of the first water tank 20, making full use of the internal space of the box body 10, and improving the space utilization rate of the entire box body 10.

The minimum width of the flared section 101411 is greater than or equal to the width of the straight section 101412. During the installation of the first water tank 20, the first hook 27 is first inserted into the flared section 101411, increasing the probability of the first hook 27 being successfully inserted into the first limiting hole 10141. Under the action of gravity, the first hook 27 slides downward from the flared section 101411 to the straight section 101412, thereby finally achieving the installation and positioning of the first water tank 20.
