Description

Technical Field

[0001] This utility model relates to the field of water purification equipment technology, specifically to a water production system and water purification equipment. Background Technology

[0002] In traditional under-sink water purifiers, tap water typically flows sequentially through a composite filter for pre-filtration, is pressurized by a pressure-regulating pump, undergoes deep purification through an RO filter (reverse osmosis membrane filter), and then undergoes post-filtration through another composite filter before finally flowing to the user's water intake. The water flow rate depends primarily on the filter's flux and the pressure-regulating pump's power. Therefore, to meet high-flow-rate user demands, a filter with a larger flux and a more powerful pressure-regulating pump are required. However, high-powered pressure-regulating pumps generate more noise and vibration during operation, reducing the user experience. Utility Model Content

[0003] In view of this, the present invention provides a water production system and water purification equipment to solve the problem of poor user experience when using large amounts of water.

[0004] In a first aspect, this utility model provides a water purification system, comprising: The water circuit board is provided with a first water inlet, a second water inlet and a first water outlet, and the first water outlet is connected to the water outlet component; The water production module is equipped with a purified water outlet, which is connected to the first water inlet. The water storage module is equipped with a water storage outlet, which is connected to the second water inlet.

[0005] Beneficial effects: By setting a first water inlet and a second water inlet on the water circuit board, with the first inlet connected to the water production module and the second inlet connected to the water storage module, simultaneous supply of two water sources can be achieved. After the pre-stored water provided by the water storage module and the instant purified water provided by the water production module are mixed inside the water circuit board, the mixture flows to the water outlet component through the first outlet. Utilizing the instant supply capacity of the pre-stored water in the water storage module, the instantaneous water flow rate can be increased, improving the overall water output speed of the system. This achieves the effect of high-flow-rate water output in a short time without changing the power of the pressure-stabilizing pump, meeting the user's high-flow-rate water intake needs, optimizing the user's water intake experience, and solving the problem of poor user experience when extracting water at high flow rates.

[0006] In one optional embodiment, a heating module is further included, wherein the water inlet of the heating module is connected to the water storage outlet, and the water outlet of the heating module is connected to the second water inlet.

[0007] Beneficial effects: By connecting the heating module in series between the water outlet of the water storage module and the second water inlet of the water circuit board, the pre-stored water in the water storage module can be heated on demand. The heated hot water is injected into the water circuit board and mixed with the water flowing directly from the water production module. Hot or warm water that meets the user's set temperature is directly output at the water outlet component, eliminating the need for additional boiling steps, improving the convenience of instant hot water access, and optimizing the overall user experience.

[0008] In one optional embodiment, a power pump is further included, the inlet of which is connected to the water storage outlet, and the outlet of which is connected to the water inlet of the heating module.

[0009] Beneficial effects: By connecting the inlet of the power pump to the outlet of the water storage module and the outlet to the inlet of the heating module, the driving force of the power pump can increase the water pressure and flow rate, ensuring smoother and more efficient water flow from the storage module into the heating module. Even when the water level in the storage module is low, a stable water supply can be guaranteed, avoiding unstable water output due to insufficient water pressure, thus improving water output efficiency and reliability.

[0010] In one optional embodiment, the water circuit board is further provided with a second water outlet, and the water storage module is further provided with a water storage inlet, wherein the second water outlet and the water storage inlet are connected.

[0011] Beneficial effects: By connecting the second outlet of the water circuit board to the water inlet of the water storage module, water circulation and replenishment within the water system can be achieved. When the water volume in the water storage module is insufficient, water from the water production module flows through the water circuit board and through the second outlet to the water storage inlet, promptly replenishing the water volume of the water storage module and preventing insufficient water storage from affecting the high-flow-rate water output function.

[0012] In one optional implementation, the water storage module includes: The water storage tank is equipped with the aforementioned water outlet; An insulation layer covers the outside of the water storage tank.

[0013] Beneficial effects: The water storage tank receives replenishment water from the second outlet of the water circuit board through the water inlet, and then supplies water to components such as the heating module through the water outlet. This provides a stable carrier for the water storage and transportation of the entire water circuit system, ensuring the orderly operation of the water supply process. The outer insulation layer effectively reduces heat exchange between the water in the storage tank and the external environment. When the water storage module stores hot water, it can reduce heat loss, extend the water temperature maintenance time, and allow users to obtain water at a suitable temperature more quickly when hot water is needed, improving ease of use.

[0014] In one optional embodiment, the top wall of the water storage tank is provided with mounting holes, and the water storage module further includes a liquid level detection component, the liquid level detection component comprising: The connector is fixed to the top wall of the water storage tank; The probe assembly has its top end fixedly connected to the connector, and its bottom end extends through the mounting hole into the interior of the water storage tank.

[0015] Beneficial effects: The mounting holes on the top wall of the water tank provide a stable installation position for the liquid level detection component. The connector is fixed to the top wall of the water tank, which facilitates the overall disassembly and maintenance of the component and ensures that the entire detection component is firmly installed, guaranteeing the stability of the detection. Furthermore, the top-mounted installation avoids the sealing complexity and weakening of strength that may result from openings in the side wall of the water tank, simplifying the structure and reducing the risk of leakage. The top of the probe component is fixed to the connector, and the bottom extends into the water tank through the mounting hole, allowing direct contact with the water body and accurate monitoring of the water level in the water tank. By monitoring the water level in real time, the water replenishment mechanism can be triggered in time when the water level is too low to avoid insufficient water supply; and water replenishment can be stopped when the water level is too high to prevent water overflow and waste or equipment damage.

[0016] In one alternative implementation, the probe assembly includes: The first probe has its bottom end extending into the bottom area of ​​the water storage tank; The second probe extends into the water tank and is positioned above the bottom of the first probe. The third probe has its bottom end extending into the water tank and positioned above the bottom end of the second probe. The first probe and the second probe constitute a first detection circuit. When the liquid level is lower than the bottom of the second probe, the first detection circuit is disconnected and a first liquid level signal is generated. The first probe and the third probe constitute a second detection circuit. When the liquid level is higher than the bottom of the third probe, the second detection circuit is turned on and generates a second liquid level signal.

[0017] Beneficial effects: The probe assembly includes a first probe with its bottom end located at the bottom of the water storage tank, a second probe with its bottom end located above the bottom end of the first probe, and a third probe with its bottom end located above the bottom end of the second probe. The first and second probes form a first detection loop, and the first and third probes form a second detection loop. When the liquid level is below the bottom end of the second probe, the first detection loop disconnects and generates a first liquid level signal, promptly alerting the tank to insufficient water and triggering a water replenishment mechanism to ensure adequate water storage. Conversely, when the liquid level is above the bottom end of the third probe, the second detection loop connects and generates a second liquid level signal, promptly indicating that the tank is full and stopping water replenishment to avoid water waste and equipment damage. The layered arrangement of the first, second, and third probes enables precise monitoring of different liquid levels within the water storage tank, improving the reliability of the water storage module's operation.

[0018] In one optional embodiment, the water storage module further includes a sealing element disposed between the connector and the top wall of the water storage tank; and the sealing element has a through hole, through which the bottom end of the probe assembly extends into the interior of the water storage tank.

[0019] Beneficial effects: The water storage module has a sealing element between the connector and the top wall of the water storage tank, and the sealing element has a through hole for the bottom end of the probe assembly to pass through. The sealing element can fit tightly against the connector and the top wall of the water storage tank, effectively preventing water in the water storage tank from seeping out from the gap between the two, playing a good sealing role, avoiding water waste and equipment damage due to water leakage, and ensuring the normal operation environment of the water storage module.

[0020] In one alternative embodiment, the seal has a protrusion on the side near the water tank, the protrusion being disposed in the gap between the probe assembly and the wall of the mounting hole.

[0021] Beneficial effects: By providing a protrusion on the seal, the gap between the probe assembly and the mounting hole wall is filled, effectively preventing water leakage from the water tank. This compensates for potential sealing dead spots that may exist when relying solely on the flat surface of the seal, improving overall sealing performance and more reliably preventing resource waste and equipment damage caused by leakage. Simultaneously, the tight contact between the protrusion and the probe assembly and the mounting hole wall provides lateral support for the probe assembly, further limiting its sway or displacement, making the probe assembly installation more stable, and ensuring that the accuracy of liquid level monitoring is not affected by equipment vibration or other factors.

[0022] In one optional embodiment, the water storage tank is further provided with an exhaust port, and the water circuit board is further provided with: The air inlet is connected to the exhaust outlet; The air outlet connects to the exhaust assembly.

[0023] Beneficial effects: By connecting the vent of the water storage tank to the air inlet of the water circuit board, and connecting the air outlet of the water circuit board to the exhaust assembly, a gas discharge path is formed, ensuring the balance of air pressure inside the water storage tank. When the water storage tank is replenished or drained, the internal air pressure changes. The vent can guide excess gas in the tank through the air inlet to the water circuit board, and then discharge it through the exhaust assembly. This avoids deformation and leakage of the water storage tank due to excessive air pressure, or affects the efficiency of water intake and discharge due to excessive air pressure. At the same time, timely gas discharge reduces air bubbles generated in the water due to air pressure issues, preventing air bubbles from interfering with the monitoring accuracy of the liquid level detection component, and ensuring the accuracy of liquid level detection. Furthermore, guiding the discharged gas to the water circuit board and finally discharging it through the exhaust assembly effectively prevents any steam, odors, or volatile substances that may be present in the water tank from directly escaping into the equipment or environment, maintaining the cleanliness of the equipment and improving user comfort and safety.

[0024] Secondly, this utility model also provides a water purification device, including the aforementioned water purification system.

[0025] Beneficial effects: The water purification equipment of this utility model includes the above-mentioned water production system and has all the technical effects of the above-mentioned water production system.

[0026] In one alternative implementation, the water purification device is an under-sink water purifier. Attached Figure Description

[0033] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0034] The following is combined with Figures 1 to 6 The following describes embodiments of the present invention.

[0035] According to an embodiment of the present invention, a water production system is provided, including a water circuit board 10, a water production module 20, and a water storage module 30; the water circuit board 10 is provided with a first water inlet, a second water inlet 11, and a first water outlet 12, the first water outlet 12 being connected to a water outlet component; the water production module 20 is provided with a purified water outlet, the purified water outlet being connected to the first water inlet; the water storage module 30 is provided with a water storage outlet 311, the water storage outlet 311 being connected to the second water inlet 11.

[0036] In the above embodiment, by setting a first water inlet and a second water inlet 11 on the water circuit board 10, wherein the first water inlet is connected to the water production module 20 and the second water inlet 11 is connected to the water storage module 30, the simultaneous supply of two water sources can be realized. After the pre-stored water provided by the water storage module 30 and the instant purified water provided by the water production module 20 are mixed inside the water circuit board 10, the water flows to the water outlet component through the first water outlet 12. By utilizing the instant supply capacity of the pre-stored water in the water storage module 30, the instantaneous water flow rate can be increased, and the overall water output speed of the system can be improved. This achieves the effect of large flow rate water output in a short time without changing the power of the pressure stabilizing pump, meeting the user's large flow rate water demand, optimizing the user's water intake experience, and solving the problem of poor user experience when taking large flow rates of water.

[0037] In a specific implementation, the purified water outlet of the water production module 20 is directly connected to the first water inlet via a connection interface; or the purified water outlet of the water production module 20 is connected to the first water inlet via an inlet pipe.

[0038] In a specific implementation, the water purification module 20 operates in the same manner as traditional water purification methods. Tap water sequentially passes through a pre-filter, a pressure-stabilizing pump, an RO filter, and a post-filter to complete the purification process. The pre-filter and post-filter are integrated into a composite filter, simplifying the overall structure. Under the pressure of the pressure-stabilizing pump, the tap water undergoes reverse osmosis filtration through the RO filter, efficiently removing impurities and pollutants from the water, ultimately resulting in pure water.

[0039] In a specific implementation, the water outlet assembly includes a water outlet pipe and a water outlet faucet. The two ends of the water outlet pipe are connected to the first water outlet 12 and the water outlet faucet, respectively. Water in the water circuit board 10 flows into the water outlet pipe from the first water outlet 12 and then flows out from the water outlet faucet.

[0040] Specifically, the water outlet pipe is a PE pipe (polyethylene pipe), which has high hygiene and safety, meets drinking water standards, and has no toxic substances released; in addition, the inner wall is smooth, does not easily form scale, and has a higher water delivery efficiency than metal pipes.

[0041] In one embodiment, the heating module 40 is further included, with its inlet 41 connected to the water storage outlet 311 and its outlet 42 connected to the second inlet 11.

[0042] In the above embodiment, by connecting the heating module 40 in series between the water storage outlet 311 of the water storage module 30 and the second water inlet 11 of the water circuit board 10, the pre-stored water in the water storage module 30 is heated on demand. The heated hot water is injected into the water circuit board 10 and mixed with the water flowing directly from the water production module 20. Hot or warm water that meets the user's set temperature is directly output at the water outlet component, eliminating the extra step of boiling water, improving the convenience of instant hot water access, and optimizing the overall user experience.

[0043] Specifically, since the water storage module 30 supplies water to the water source simultaneously with the water production module 20, it not only retains the ability to provide a large flow of water in a short time, but also heats the water source of the water storage module 30 so that the mixed water can quickly reach a suitable temperature. Thus, while ensuring the water output speed and flow rate, it can also ensure that the water output temperature meets the user's needs, thereby optimizing the user's experience.

[0044] In one embodiment, a power pump 50 is also included, the inlet of which is connected to the water storage outlet 311, and the outlet of which is connected to the water inlet 41 of the heating module 40.

[0045] In the above embodiment, the inlet of the power pump 50 is connected to the water storage outlet 311, and the outlet is connected to the water inlet 41 of the heating module 40. With the driving force of the power pump 50, the water pressure and flow rate can be increased, ensuring smoother and more efficient water flow from the water storage module 30 into the heating module 40. Even when the water level in the water storage module 30 is low, a stable water supply can be guaranteed, avoiding unstable water output due to insufficient water pressure, thus improving water output efficiency and reliability.

[0046] In a specific implementation, the water storage outlet 311 is connected to the inlet of the power pump 50 via a first connecting pipe 60; the outlet of the power pump 50 is directly connected to the water inlet 41 of the heating module 40 via a connecting interface; and the water outlet 42 of the heating module 40 is connected to the second water inlet 11 via a second connecting pipe 70.

[0047] In one embodiment, the water circuit board 10 is further provided with a second water outlet 13, and the water storage module 30 is further provided with a water storage inlet 312, and the second water outlet 13 and the water storage inlet 312 are connected.

[0048] In the above embodiment, the second outlet 13 of the water circuit board 10 is connected to the water inlet 312 of the water storage module 30, enabling water circulation and replenishment within the water system. When the water volume in the water storage module 30 is insufficient, water from the water production module 20 flows through the water circuit board 10 and through the second outlet 13 to the water inlet 312, promptly replenishing the water volume of the water storage module 30 and preventing insufficient water storage from affecting the large-flow water output function.

[0049] In a specific implementation, the second outlet 13 and the water storage inlet 312 are connected by a circulation pipeline 80.

[0050] In a specific implementation, the purified water provided by the water production module 20 flows into the water circuit board 10 through the inlet pipe, the first inlet, and then flows sequentially through the circulation pipe 80, the water storage module 30, the first connecting pipe 60, the power pump 50, the heating module 40, and the second connecting pipe 70. It then flows into the water circuit board 10 through the second inlet 11 and then re-enters the water storage module 30 through the circulation pipe 80, forming an internal water circulation path.

[0051] Specifically, by setting up an internal water circulation path, the water in the water storage module 30 can flow continuously, effectively reducing the generation of stagnant water areas and helping to maintain the cleanliness and quality of the stored water.

[0052] Specifically, when the user is not drawing water, the water will flow through the heating module 40 for preheating via the internal water circulation path. Through processes such as water production, heating, and storage, the water storage module 30 will be filled with hot water, thereby increasing the initial temperature of the water stored in the water storage module 30.

[0053] Specifically, the water stored in the water storage module 30 is heated through an internal water circulation path. Since the temperature of the water stored in the water storage module 30 is already higher than the room temperature, the heating time required when the terminal takes water is shortened. When the user needs to take hot water, there is no need to start heating from the room temperature. The reheating time is greatly shortened, thereby achieving the effect of obtaining a large flow of hot water in a short time. This not only meets the user's immediate water needs but also further optimizes the user's water taking experience.

[0054] In a specific implementation, the purified water provided by the water production module 20 flows into the water circuit board 10 through the water inlet pipe and then flows to the water outlet component through the first water outlet 12, forming a normal temperature water outlet flow path. The normal temperature water outlet flow path meets the user's demand for normal temperature water.

[0055] In a specific implementation, the purified water provided by the water production module 20 flows into the water circuit board 10 through the inlet pipe and the first inlet. The pre-stored water in the water storage module 30 flows sequentially through the first connecting pipe 60, the power pump 50, the heating module 40, and the second connecting pipe 70, and then flows into the water circuit board 10 through the second inlet 11. The two water sources mix in the water circuit board 10 and then flow to the water outlet component through the first outlet 12, thus forming a high-flow-rate water flow path. The high-flow-rate water flow path meets the user's demand for high-flow-rate water.

[0056] In a specific implementation, the purified water provided by the water production module 20 flows into the water circuit board 10 through the inlet pipe, the first inlet, and then flows sequentially through the circulation pipe 80, the water storage module 30, the first connecting pipe 60, the power pump 50, the heating module 40, and the second connecting pipe 70. It then flows into the water circuit board 10 through the second inlet 11 and then flows to the water outlet component through the first outlet 12, forming a hot water outlet flow path. This hot water outlet flow path satisfies the user's hot water demand.

[0057] Specifically, when the water storage module 30 is short of water, the purified water produced can be directly heated to the user's required water temperature through the hot water outlet flow path.

[0058] In this embodiment, during the cyclic heating process, there is no limitation on the heating temperature of the water stored in the water storage module 30. For example, the water stored in the water storage module 30 can be heated to 60°C, which can quickly reach the water temperature required by the user, shorten the heating waiting time when the user takes water, and meet the user's immediate need for high-temperature hot water more quickly.

[0059] In one embodiment, the water storage module 30 includes a water storage tank 31 and an insulation layer 32; the water storage tank 31 is provided with a water inlet 312 and a water outlet 311; the insulation layer 32 covers the outside of the water storage tank 31.

[0060] In the above embodiment, the water storage tank 31 receives replenishment water from the second outlet 13 of the water circuit board 10 through the water inlet 312, and then supplies water to components such as the heating module 40 through the water outlet 311, providing a stable carrier for the water storage and transportation of the entire water circuit system and ensuring the orderly operation of the water supply process. The outer insulation layer 32 can effectively reduce the heat exchange between the water in the water storage tank 31 and the external environment. When the water storage module 30 stores hot water, it can reduce heat loss, extend the water temperature maintenance time, and allow users to obtain water at a suitable temperature more quickly when hot water is needed, improving the convenience of use.

[0061] In one embodiment, the top wall of the water storage tank 31 is provided with a mounting hole 313, and the water storage module 30 further includes a liquid level detection component 33, which includes a connector 331 and a probe component 332; the connector 331 is fixed to the top wall of the water storage tank 31; the top end of the probe component 332 is fixedly connected to the connector 331, and the bottom end extends through the mounting hole 313 into the interior of the water storage tank 31.

[0062] In the above embodiment, the mounting hole 313 on the top wall of the water storage tank 31 provides a stable installation position for the liquid level detection component 33. The connector 331 is fixed to the top wall of the water storage tank 31, which facilitates the overall disassembly and maintenance of the component and ensures that the entire detection component is firmly installed, guaranteeing the stability of the detection. Furthermore, the top-mounted installation avoids the sealing complexity and weakening of strength that may result from openings in the side wall of the water tank, simplifying the structure and reducing the risk of leakage. The top of the probe component 332 is fixed to the connector 331, and the bottom extends into the interior of the water storage tank 31 through the mounting hole 313, allowing it to directly contact the water and accurately monitor the water level in the water storage tank 31. By monitoring the water level information in real time, the water replenishment mechanism can be triggered in time when the water level is too low to avoid insufficient water supply; and the water replenishment can be stopped when the water level is too high to prevent water overflow and waste or equipment damage.

[0063] In a specific embodiment, the connector 331 is detachably connected to the water storage tank 31 by fasteners. Specifically, the fasteners can be screws.

[0064] In one embodiment, the probe assembly 332 includes a first probe 3321, a second probe 3322, and a third probe 3323. The bottom end of the first probe 3321 extends into the bottom region of the water storage tank 31. The bottom end of the second probe 3322 extends into the water storage tank 31 and is located above the bottom end of the first probe 3321. The bottom end of the third probe 3323 extends into the water storage tank 31 and is located above the bottom end of the second probe 3322. The first probe 3321 and the second probe 3322 constitute a first detection circuit. When the liquid level is lower than the bottom end of the second probe 3322, the first detection circuit is disconnected and a first liquid level signal is generated. The first probe 3321 and the third probe 3323 constitute a second detection circuit. When the liquid level is higher than the bottom end of the third probe 3323, the second detection circuit is turned on and a second liquid level signal is generated.

[0065] In the above embodiment, the probe assembly 332 includes a first probe 3321 with its bottom end located in the bottom region of the water storage tank 31, a second probe 3322 with its bottom end located above the bottom end of the first probe 3321, and a third probe 3323 with its bottom end located above the bottom end of the second probe 3322. The first probe 3321 and the second probe 3322 form a first detection circuit, and the first probe 3321 and the third probe 3323 form a second detection circuit. When the liquid level is lower than the bottom end of the second probe 3322, the first detection circuit is disconnected and a first liquid level signal is generated, which can promptly remind that the water in the water storage tank 31 is insufficient, thereby quickly triggering the water replenishment mechanism to ensure sufficient water storage. When the liquid level is higher than the bottom end of the third probe 3323, the second detection circuit is turned on and a second liquid level signal is generated, which can promptly indicate that the water is full, thereby stopping water replenishment and avoiding water waste and equipment damage. The layered arrangement of the first probe 3321, the second probe 3322, and the third probe 3323 enables precise monitoring of different liquid levels in the water storage tank 31, thereby improving the reliability of the water storage module 30.

[0066] In a specific implementation, when the liquid level is lower than the bottom of the second probe 3322, the first detection circuit is disconnected and a first liquid level signal is generated, and water is replenished to the interior of the water storage module 30 through the internal water circulation flow path.

[0067] In one embodiment, the water storage module 30 further includes a sealing element 34, which is disposed between the connector 331 and the top wall of the water storage tank 31; and the sealing element 34 is provided with a through hole, through which the bottom end of the probe assembly 332 passes in sequence through the through hole and the mounting hole 313 and extends into the interior of the water storage tank 31.

[0068] In the above embodiment, the water storage module 30 is provided with a sealing element 34 between the connector 331 and the top wall of the water storage tank 31, and the sealing element 34 is provided with a through hole for the bottom end of the probe assembly 332 to pass through. The sealing element 34 can fit tightly against the connector 331 and the top wall of the water storage tank 31, effectively preventing water in the water storage tank 31 from seeping out from the gap between the two, playing a good sealing role, avoiding water waste and equipment damage due to water leakage, and ensuring the normal operation environment of the water storage module 30.

[0069] In one embodiment, the seal 34 has a protrusion 341 on the side near the water tank 31, and the protrusion 341 is disposed in the gap between the probe assembly 332 and the wall of the mounting hole 313.

[0070] In the above embodiment, by providing a protrusion 341 on the seal 34, the gap between the probe assembly 332 and the wall of the mounting hole 313 is filled, effectively preventing water in the water tank 31 from leaking through the gap. This compensates for any potential sealing dead angles that might exist if the seal 34 is simply attached to the surface, improving overall sealing performance and more reliably preventing resource waste and equipment damage caused by leakage. Simultaneously, the close contact between the protrusion 341 and the probe assembly 332 and the wall of the mounting hole 313 provides lateral support for the probe assembly 332, further limiting its swaying or displacement, making the installation of the probe assembly 332 more stable, and ensuring that the accuracy of liquid level monitoring is not affected by factors such as equipment vibration.

[0071] In one embodiment, the water storage tank 31 is also provided with an exhaust port 314, and the water circuit board 10 is also provided with an air inlet 14 and an air outlet. The exhaust port 314 is connected to the air inlet 14, and the air outlet is connected to the exhaust assembly.

[0072] In the above embodiment, by connecting the exhaust port 314 of the water storage tank 31 to the air inlet 14 of the water circuit board 10, and connecting the air outlet of the water circuit board 10 to the exhaust assembly, a gas discharge path is formed, ensuring the balance of the internal air pressure of the water storage tank 31. When the water storage tank 31 is replenished or drained, the internal air pressure will change. The exhaust port 314 can guide the excess gas in the tank into the water circuit board 10 through the air inlet 14, and then discharge it through the exhaust assembly through the air outlet. This avoids deformation and leakage of the water storage tank 31 due to excessively high air pressure, or affects the efficiency of water intake and discharge due to excessively low air pressure. At the same time, timely discharge of gas can reduce the bubbles generated in the water due to air pressure problems, prevent bubbles from interfering with the monitoring accuracy of the liquid level detection component 33, and ensure the accuracy of liquid level detection. Furthermore, guiding the discharged gas to the water circuit board 10 and finally discharging it through the exhaust assembly effectively prevents the steam, odor, or volatile substances that may exist in the water tank from directly escaping into the equipment or environment, maintaining the cleanliness of the equipment and improving user comfort and safety.

[0073] Specifically, such as Figure 6 As shown, the insulation layer 32 is provided with through holes corresponding to the water inlet 312, water outlet 311 and vent 314, so that the water inlet 312, water outlet 311 and vent 314 can be connected to the external pipeline through the corresponding through holes.

[0074] Preferably, the exhaust assembly includes a gas filter unit that can filter the exhaust gas to reduce the spread of odors or impurities.

[0075] In a specific implementation, the vent 314 of the water storage tank 31 is connected to the air inlet 14 of the water circuit board 10 via an vent pipe 90.
