Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more particularly to a humidifier. Background Technology

[0002] During use, mineral ions such as calcium and magnesium in the water can easily deposit on the evaporative cooling pad, forming limescale. As usage time increases, this limescale buildup gradually clogs the micropores of the cooling pad, reducing its absorbency and breathability, increasing air resistance, and affecting airflow efficiency, ultimately decreasing the humidifier's humidification capacity. Furthermore, limescale buildup provides a favorable environment for the growth of bacteria and mold, further impacting the humidifier's hygiene and lifespan. Utility Model Content

[0045] like Figure 1 and Figure 2 As shown in the figure, this application embodiment provides a humidifier 1, which includes a body 10, a fan assembly 30, and a wettable substrate 20. The body 10 is provided with an air inlet 101 and an air outlet 102. When the fan assembly 30 is working, it generates negative pressure, and air from the indoor environment enters through the air inlet 101, then flows through the wettable substrate 20 and is discharged from the air outlet 102, thereby increasing the humidity of the airflow entering the indoor environment.

[0046] The wettable substrate 20 can be a filter material made of hydrophilic polymer composite material or natural / synthetic fiber fabric. The surface of the wettable substrate 20 can be treated with a nano-coating or gradient porosity to optimize capillary water absorption performance. The wettable substrate 20 forms a high specific surface area air-water contact interface through a multi-layer composite or three-dimensional honeycomb structure, and the wettable substrate 20 can be configured with antibacterial agents or anti-mildew coatings to resist biofouling. A support frame integrating guide channels or asymmetric corrugated units can be added to the wettable substrate 20 to directionally guide the airflow and moisture diffusion path.

[0047] like Figure 2 As shown, the humidifier 1 also includes a liquid supply assembly 60. The liquid supply assembly 60 is used to supply liquid to the wettable substrate 20 to keep the wettable substrate 20 moist to achieve the humidification function, or to clean the wettable substrate 20 to improve the cleanliness of the wettable substrate 20.

[0048] The liquid supply assembly 60 can selectively supply humidifying water or a cleaning solution containing a cleaning medium to the wettable substrate 20. The liquid supply assembly 60 can supply humidifying water or a cleaning solution containing a cleaning medium to the wettable substrate 20, with the humidifying water and the cleaning solution containing the cleaning medium stored independently and physically isolated. The humidifying water can be filtered purified water or softened water to reduce the probability of scale formation on the wettable substrate 20. The cleaning solution containing the cleaning medium can be an acidic solution (such as citric acid solution, acetic acid solution, etc.) or a disinfectant containing antibacterial components (such as diluted sodium hypochlorite solution, hydrogen peroxide solution, etc.) to kill microorganisms growing on the wettable substrate 20. This application embodiment uses citric acid as the cleaning medium for illustrative purposes.

[0049] like Figure 2As shown, the humidifier 1 may include a first water tank 40 and a second water tank 50. The first water tank 40 and the second water tank 50 are detachably disposed from the body 10, and the first water tank 40 and the second water tank 50 may be placed inside the body 10. The liquid supply assembly 60 may be selectively connected to the first water tank 40 to provide humidifying water to the wettable substrate 20, or the liquid supply assembly 60 may be selectively connected to the second water tank 50 to provide cleaning liquid to the wettable substrate 20.

[0050] In one possible embodiment, the humidifying water can be stored in a first water tank 40, and the cleaning liquid containing the cleaning medium can be stored in a second water tank 50. The first water tank 40 and the second water tank 50 can be two separate water tanks, physically isolated to prevent the humidifying water and the cleaning liquid from mixing. Alternatively, the first water tank 40 and the second water tank 50 can be integrated into the same housing, but formed into two independent liquid storage chambers by an internal partition.

[0051] In another possible embodiment, the first water tank 40 and the second water tank 50 can store clean water respectively. The liquid supply assembly 60 can be configured with independent first pipes 604 and second pipes 605 that are in liquid communication with the wettable substrate 20, respectively, for the first water tank 40 and the second water tank 50. The second pipe 605 can be provided with a storage box 610 for containing cleaning media. When the water in the second water tank flows through the storage box 610, the clean water mixes with the cleaning media to form a cleaning solution. In this way, the cleaning solution can be prepared when the cleaning mode is activated, improving the activity of the cleaning solution.

[0052] To achieve the humidification performance of the wettable substrate 20, the volume of the first water tank 40 can be slightly smaller than the volume of the second water tank 50. For example, the volume of the first water tank 40 can be 2-3 liters, and the volume of the second water tank 50 can be 3-5 liters, so as to facilitate the recycling of waste liquid in the second water tank 50.

[0053] The humidifier 1 may include a humidification mode. In the humidification mode, the liquid supply assembly 60 is connected to the water path of the first water tank 40, and humidifying water is delivered to the wettable substrate 20. The wettable substrate 20 may include a water distributor with a porous design, so that the humidifying water can be evenly covered across the entire wettable substrate 20 to achieve the humidification performance of the wettable substrate 20 on the airflow passing through it.

[0054] In humidification mode, the fan assembly 30 operates at a preset speed for a set duration to generate negative pressure airflow. Air from the indoor environment enters through the air inlet 101, flows through the wettable substrate 20 soaked in humidifying water, and is then humidified and discharged from the air outlet 102.

[0055] The humidifier 1 also includes a cleaning mode. In cleaning mode, the liquid supply assembly 60 switches to a water path connected to the second water tank 50. A solution containing a cleaning medium is delivered to the wettable substrate 20. In cleaning mode, the delivery process of the liquid supply assembly 60 can maintain a low flow rate, allowing the cleaning liquid to fully wet the capillary pores of the wettable substrate 20.

[0056] In cleaning mode, when the liquid supply component 60 delivers cleaning liquid to the wettable substrate 20, the fan component 30 can stop operating to reduce the probability of cleaning liquid atomization and diffusion, while allowing the cleaning liquid to react with the wettable substrate 20 to dissolve scale and kill microorganisms.

[0057] Thus, the humidifier 1 provided in this embodiment has a humidification mode and a cleaning mode. In humidification mode, the first water tank 40 supplies liquid to the liquid supply assembly 60 to inject humidifying water into the wettable substrate 20, keeping the wettable substrate 20 moist. In cleaning mode, the second water tank 50 supplies liquid to the liquid supply assembly 60 to clean the wettable substrate 20 with cleaning liquid. Users do not need to remove the wettable substrate 20 from the unit 10 for cleaning, while still maintaining the humidification performance of the humidifier 1, improving the convenience of maintaining the wettable substrate 20. Simultaneously, when humidifying water is supplied to the wettable substrate, the fan assembly is in operation, thereby delivering the humidified airflow passing through the wettable substrate into the indoor environment. When cleaning the wettable substrate with cleaning liquid, the fan assembly stops operating to prevent the cleaning liquid from being blown into the indoor environment and causing pollution.

[0058] like Figure 2 As shown, in some embodiments, the humidifier 1 further includes a water tray 701. A wettable substrate 20 is disposed on the water tray 701 to receive liquid overflowing from the wettable substrate 20. The liquid may be humidifying water overflowing from the wettable substrate 20 in humidification mode, or cleaning liquid overflowing from the wettable substrate 20 in cleaning mode.

[0059] In some embodiments, the second water tank 50 may include a first liquid storage chamber and a second liquid storage chamber that are isolated from each other. The first liquid storage chamber is used to contain cleaning liquid or clean water (the cleaning medium is disposed in the liquid supply assembly 60). The first liquid storage chamber is connected to the liquid supply assembly 60, and the second liquid storage chamber is connected to the water receiving tray 701.

[0060] The second water tank 50 adopts a compartmentalized design, comprising a first liquid storage chamber and a second liquid storage chamber that are isolated from each other. The first liquid storage chamber is used for the cleaning liquid supplied to the wettable substrate 20, and may be equipped with a first outlet connected to the liquid supply assembly 60. The second liquid storage chamber is used to collect waste liquid returning from the receiving tray 701, and has an inlet on its side wall connected to the drain pipe of the receiving tray 701. The first and second liquid storage chambers are physically isolated by an integrally molded leak-proof partition, preventing the cleaning liquid and waste liquid from mixing.

[0061] The waste liquid recovery function of the second liquid storage chamber helps maintain the internal cleanliness of the humidifier 1. After the cleaning mode operation is completed, the used cleaning fluid, carrying dissolved scale and detached impurities, flows into the water tray 701 and is then collected in the second liquid storage chamber through the drain pipe. This reduces the potential secondary pollution caused by waste liquid residue in the water tray 701 and also prevents waste liquid from overflowing from the unit 10 and polluting the indoor environment. Users only need to periodically disassemble the second water tank 50 and clean the second liquid storage chamber to complete the waste liquid disposal, simplifying the maintenance process of the humidifier 1.

[0062] The volume of the first liquid storage chamber can be slightly smaller than that of the second liquid storage chamber. This ensures that the cleaning fluid has enough capacity to complete the cleaning process, while also reserving sufficient space for waste liquid collection.

[0063] like Figure 2 As shown, in some embodiments, the liquid supply assembly 60 includes a liquid supply line 601. One end of the liquid supply line 601 extends to or directly contacts the wettable substrate 20, or is connected to a water distributor of the wettable substrate 20, thereby delivering liquid to the surface or internal pores of the wettable substrate 20. The liquid supply line 601 may be made of a flexible or rigid material, such as silicone tubing, polytetrafluoroethylene tubing, or stainless steel tubing, depending on the properties of the cleaning fluid.

[0064] like Figure 2 As shown, in some embodiments, the liquid supply assembly 60 further includes a switching valve 602. The switching valve 602 is disposed in the liquid supply line 601 and is connected to the first water tank 40 and the second water tank 50. By controlling the switching valve 602, the liquid supply line 601 can selectively draw liquid from the first water tank 40 or the second water tank 50 to adapt to different operating modes.

[0065] Specifically, the switching valve 602 can be a three-way valve, with one end connected to the first water tank 40, one end connected to the second water tank 50, and the other end connected to the wettable substrate 20. The switching valve 602 can be a solenoid valve or an electric three-way valve to allow the liquid supply line 601 to switchably draw liquid from either the first water tank 40 or the second water tank 50.

[0066] In some embodiments, the liquid supply assembly 60 further includes a pump body 603. The pump body 603 is disposed in the liquid supply line 601 and located between the switching valve 602 and the wettable substrate 20. The pump body 603 is used to drive the liquid flow.

[0067] Specifically, the pump body 603 can be a centrifugal pump, and further, the pump body 603 can be configured with frequency conversion control to adjust the humidification water flow rate according to the humidification demand in humidification mode.

[0068] In some embodiments, the second water tank 50 can store clean water, and a storage box 610 can be provided on a section of the liquid supply pipeline 601 between the switch valve 602 and the second water tank 50. The storage box 610 is detachable from the liquid supply pipeline 601. The storage box 610 is used to contain a cleaning medium, which can be at least one of solid particles, sustained-release capsules, or liquid concentrate, so that when the water in the second water tank 50 flows through the storage box 610, some or all of the cleaning medium is dissolved to prepare a cleaning solution.

[0069] When the second water tank 50 is divided into a first liquid storage chamber and a second liquid storage chamber, the liquid supply line 601 is connected to the first liquid storage chamber. When the second water tank 50 is a single chamber, the liquid supply line 601 can be connected to the top of the second water tank 50.

[0070] like Figure 3 As shown, in some embodiments, the liquid supply assembly 60 can employ a dual-pipeline independent liquid supply method. Specifically, the liquid supply assembly 60 may include a first pipe 604 and a second pipe 605 that are independent of each other. The first pipe 604 is connected to a first water tank 40, and the second pipe 605 is connected to a second water tank 50. The two pipes are used to independently supply liquid to the wettable substrate 20. When the second water tank 50 is divided into a first liquid storage chamber and a second liquid storage chamber, the second pipe 605 is connected to the first liquid storage chamber.

[0071] Specifically, the first pipeline 604 is equipped with a first valve 606 and a first water pump 607, and the second pipeline 605 is equipped with a second valve 608 and a second water pump 609.

[0072] In some embodiments, the humidifier 1 further includes a control device 80. The control device 80 is electrically connected to the first valve 606, the second valve 608, the first water pump 607, and the second water pump 609, respectively. The control device 80 can control the operating status of each switch and the water pump according to the operating mode of the humidifier 1.

[0073] The first valve 606 and the second valve 608 can each be a solenoid valve, which can be quickly opened and closed by the control device 80. The first water pump 607 and the second water pump 609 can each be a miniature centrifugal pump.

[0074] For example, in humidification mode, control device 80 can open the first valve 606 and start the first water pump 607, while keeping the second valve 608 and the second water pump 609 closed. In cleaning mode, control device 80 can open the second valve 608 and start the second water pump 609, while closing the first valve 606 and the first water pump 607. The liquid supply assembly 60, through a physically isolated dual-pipe design, reduces the probability of cross-mixing of humidification water and cleaning solution in the pipeline.

[0075] In some embodiments, the second water tank 50 can store clean water, and the second pipeline 605 can also be provided with a storage box 610. The storage box 610 is used to contain a cleaning medium, which is at least one of solid particles, slow-release capsules or liquid concentrate. The storage box 610 is detachable from the second pipeline 605 so that when the water in the second water tank 50 flows through the storage box 610, it dissolves part or all of the cleaning medium to prepare a cleaning solution.

[0076] like Figure 2 As shown, in some embodiments, the humidifier further includes a liquid return assembly 70. The liquid return assembly 70 is disposed within the body 10 and is used to recover the liquid flowing through the wettable substrate 20 to the second water tank 50, or to discharge the liquid flowing through the wettable substrate 20 to a wastewater tank. When the humidifier 1 is equipped with a wastewater tank, waste liquid can be preferentially discharged to the wastewater tank, and the second water tank 50 may no longer receive waste liquid; the second water tank 50 can be configured as a separate cavity structure.

[0077] The liquid return assembly 70 is located inside the body 10. The liquid return assembly 70 is used to recover the liquid flowing through the wettable substrate 20 and transport it to a single cavity of the second water tank 50 or a second liquid storage cavity. The recovered liquid is recycled in cleaning mode or stored in the second liquid storage cavity for centralized collection, or the liquid is discharged to a wastewater tank for centralized treatment.

[0078] In humidification mode, if the second water tank 50 is configured as a single-chamber structure, liquid overflowing from the wettable substrate 20 flows back to the second water tank 50, achieving recycling of humidification water and reducing the need for frequent refilling of the second water tank 50 by the user. In cleaning mode, the recovered cleaning solution can still be reused, saving on the cost of cleaning media. Moreover, because the acidic components in the cleaning solution can dissolve scale, the cleaning solution can maintain its cleaning ability within a preset number of cycles. During cleaning mode operation, the dissolved scale will settle at the bottom of the second water tank 50, while the cleaning solution maintains a sufficient concentration of active ingredients.

[0079] When the humidifier 1 is equipped with a wastewater tank or the body 10 is equipped with a drain outlet, the liquid return assembly 70 can return the liquid overflowing from the wettable substrate 20 to the wastewater tank inside or outside the body 10, physically isolating the dissolved scale and impurities from the second water tank 50, so that the cleaning solution remains effective.

[0080] Specifically, in cleaning mode, the cleaning fluid flowing out of the wettable substrate 20 may carry scale particles detached from the wettable substrate 20 and impurities settled in the air. If it is directly returned to the second water tank 50, contaminants will be mixed into the cleaning fluid. Collecting this waste fluid through the wastewater tank can maintain the purity of the cleaning fluid in the second water tank 50 and reduce the re-deposition of scale on the surface of the wettable substrate 20, thereby further improving the cleanliness of the wettable substrate 20.

[0081] Wastewater tanks can be equipped with viewing windows to allow users to easily understand the wastewater capacity inside.

[0082] In some embodiments, the wastewater tank is detachably mounted on the body 10.

[0083] The wastewater tank is connected to the main body 10 via a quick-release mechanism, allowing for easy assembly and disassembly with one hand. Specifically, the quick-release mechanism includes latches on both sides of the wastewater tank and corresponding guide grooves on the main body 10. When the wastewater tank is pushed into the set position along the guide groove, the latches automatically lock. Pressing the release buttons on both sides of the latches releases the lock, facilitating quick removal and placement of the wastewater tank by the user.

[0084] In some embodiments, the wastewater tank is located outside the main body 10. In this way, the main body 10 does not need to reserve space for wastewater storage, reducing the volume of the humidifier 1 and achieving further miniaturization of the humidifier 1.

[0085] The wastewater tank can be connected to the drain port on the side wall of the unit via a quick-connect coupling, enabling plug-and-play operation. The quick-connect coupling features a leak-proof design and can be equipped with an internal sealing ring to prevent leakage during wastewater transfer.

[0086] The wastewater tank can be equipped with casters at the bottom, making it easy for users to move it to a suitable location as needed. The wastewater tank can be an accessory for humidifier 1, or it can be an existing water storage container in the user's home, such as a basin or bucket.

[0087] like Figure 2 As shown, in some embodiments, the liquid return assembly 70 includes a water receiving tray 701 and a liquid return pipe 702. The water receiving tray 701 is used to support the wettable substrate 20, which is disposed above the water receiving tray 701. The water receiving tray 701 is provided with a liquid return port.

[0088] The surface of the drip tray 701 can be designed with guide grooves and overflow-proof edges to collect liquid overflowing from the wettable substrate 20. A return port is provided in the central area of ​​the drip tray 701. The return pipe 702 uses a transparent silicone hose for easy disassembly and cleaning.

[0089] A drip tray 701 is located below the wettable substrate 20 to collect liquid overflowing from the wettable substrate 20 and to provide support for the wettable substrate 20. The bottom of the drip tray 701 has a return port, which is connected to one end of a return pipe 702. The other end of the return pipe 702 is connected to a single cavity of the second water tank 50, a second liquid storage cavity within the second water tank 50, or a wastewater tank.

[0090] For example, the return line 702 is detachably connected to the inlet of the second water tank 50 via a quick-release connector. The quick-release connector uses a rotating snap-fit ​​structure, allowing for installation or removal with one hand, facilitating separate cleaning and maintenance of the second water tank 50 by the user.

[0091] For example, when the humidifier 1 is equipped with a built-in wastewater tank, the return pipe 702 can be connected to the inlet of the wastewater tank via a magnetic sealing ring. The magnetic sealing ring automatically adheres and seals when the pipes are connected, and releases the magnetic attraction by pressing the release button when the pipes are separated, thus combining leak prevention with ease of operation.

[0092] For example, when the wastewater tank is a user-configured water container, the end of the return pipe 702 is provided with a universal threaded interface, which can be screwed onto the drain port on the side wall of the unit 10. When an external water tank is connected, the drain port is opened, allowing the wastewater to be directly introduced into the user's own water storage container.

[0093] In some embodiments, the humidifier further includes a receiving box 501. The receiving box 501 is disposed on top of the second water tank 50 and is used to contain cleaning media. The receiving box 501 is provided with a discharge port 505 through which the cleaning media can be injected into the second water tank 50. When the second water tank 50 includes a first liquid storage chamber, the receiving box 501 may be disposed within the first liquid storage chamber.

[0094] like Figure 4 As shown, in some embodiments, the humidifier also includes a switch 502 disposed in the cleaning medium container 501, the switch 502 being used to open or close the discharge port 505.

[0095] The second water tank 50 includes a container 501 for storing cleaning media, and a switch 502 capable of opening and closing the container 501. The switch 502 can be an electrically operated switch 502.

[0096] The container 501 may be a sealed design and equipped with an electrically controllable switch 502. The cleaning medium may be a liquid concentrated cleaning medium, a solid cleaning powder tablet, or a slow-release cleaning capsule, etc.

[0097] Before or during the cleaning mode, the switch 502 can open the container 501 to add the cleaning medium into the pre-stored water in the second water tank 50 to prepare the cleaning solution.

[0098] For example, the duration for which the switch 502 opens the receiving box 501 is positively correlated with the air pressure difference across the wettable substrate 20. The switch 502 determines the opening duration according to the dispensing amount determined based on the air pressure setting, which allows the cleaning medium in the receiving box 501 to be quantitatively dispensed into the second water tank 50.

[0099] In this way, the switch 502 can control the amount of cleaning medium dispensed precisely according to the actual degree of blockage of the wettable substrate 20, which can achieve the cleaning effect while reducing the waste of cleaning medium.

[0100] like Figure 2 As shown, in some embodiments, the humidifier further includes a pH sensor 503 and a control device 80. The pH sensor 503 is disposed in the second water tank 50.

[0101] The control device 80 is connected to the pH sensor 503 and the switch 502. The pH sensor 503 is used to monitor the acidity or alkalinity of the cleaning solution in the second water tank 50 in real time and feeds back the detected pH value to the control device 80. When the pH value of the cleaning solution exceeds the preset pH range, the control device 80 opens the switch 502 to add cleaning medium to the second water tank 50 to maintain the effectiveness of the cleaning solution.

[0102] When the return liquid assembly 70 is connected to the second water tank 50 in a single chamber, the pH value of the cleaning solution in the second water tank 50 will gradually increase or decrease during use because the cleaning solution continuously dissolves scale by deactivating active ingredients. This can exceed the preset pH range, leading to a decrease in the cleaning efficiency of the cleaning solution. Therefore, during the cleaning process, the pH sensor 503 monitors the acidity or alkalinity of the cleaning solution in the second water tank 50 in real time and feeds the detection data back to the control device 80. The control device 80 dynamically adjusts the amount of cleaning medium added based on the pH value changes to replenish the cleaning medium.

[0103] For example, when the cleaning medium is acidic, the preset pH range can be 0-6; when the cleaning medium is acidic, the preset pH range can be 8-14.

[0104] Taking citric acid as a cleaning medium as an example, if the pH value of the solution in the second water tank 50 rises, the control device 80 can automatically replenish the cleaning solution by operating the switch 502, which can maintain the optimal working pH value range of the cleaning solution (such as 2-3) and keep the cleaning solution effective.

[0105] like Figure 2 As shown, in some embodiments, the humidifier further includes a cleanliness detection element 504. The cleanliness detection element 504 is disposed in the second water tank 50.

[0106] To reduce the risk of excessive contamination of the cleaning fluid in the second water tank 50 due to the backflow of the recycled cleaning fluid into the second water tank 50 with a single cavity, a cleanliness detection element 504 may be provided in the second water tank 50. The cleanliness detection element 504 may be an optical sensor or a conductivity sensor to monitor the cleanliness of the cleaning fluid in the second water tank 50 in real time.

[0107] If the cleanliness value obtained by the cleanliness detection element 504 is lower than the first preset threshold, it indicates that the cleaning liquid in the second water tank 50 no longer meets the cleaning requirements. The humidifier 1 can stop continuing to execute the cleaning mode, and the liquid supply component 60 can switch to the first water tank 40 to execute the rinsing mode of the wettable substrate 20, thereby reducing the possibility of secondary pollution caused by the residual cleaning liquid in the wettable substrate 20 when the humidification mode is subsequently run.

[0108] like Figure 2 As shown, in some embodiments, the humidifier 1 further includes an interactive device. The interactive device may be a voice interactive device, a visual interactive device, or a combination of both.

[0109] If the cleanliness value obtained by the cleanliness detection element 504 is lower than the first preset threshold, it means that the cleaning liquid in the second water tank 50 no longer meets the cleaning requirements, and the humidifier 1 can prompt the user to clean the second water tank 50 through the interactive device.

[0110] like Figure 1 As shown, in some embodiments, in the height direction, the fan assembly 30 and the wettable substrate 20 can be located in the middle of the first water tank 40 and the second water tank 50. The first water tank 40 and the second water tank 50 are respectively arranged on both sides of the air duct of the fan assembly 30. The hollow clearance portion 401 formed in the first water tank 40 will not block the air duct, and provides sufficient capacity space for the first water tank 40 and the second water tank 50.

[0111] It is understood that the first water tank 40 is located at the top, using gravity to allow the humidifying water to flow more smoothly into the wettable substrate 20. The fan assembly 30 and the wettable substrate 20 are centrally arranged, forming the core humidification area. The second water tank 50 is located below the wettable substrate 20, and the height difference enables the automatic return collection of cleaning liquid and humidifying water overflowing from the wettable substrate 20.

[0112] Thus, by arranging the first water tank 40, fan assembly 30, wettable substrate 20, and second water tank 50 along the vertical direction in this embodiment, the space utilization of the humidifier 1 can be significantly optimized, since the horizontal space occupied by the humidifier 1 is more limited than the vertical space in an indoor environment. Furthermore, by placing the heavier second water tank 50 at the lower part of the body 10, the center of gravity of the entire unit is lowered, enhancing the stability of the humidifier 1.

[0113] In some embodiments, the first water tank 40 can be detachably connected to the body 10 via a connecting structure to achieve structural stability of the first water tank 40.

[0114] In some embodiments, the first water tank 40 and the second water tank 50 can be separated from the body 10.

[0115] The first water tank 40 and the second water tank 50 are detachable from the main body 10, making it convenient for users to add water to the first water tank 40 and the second water tank 50. Since the second water tank 50 is used to hold recycled liquids and acidic or alkaline cleaning solutions, separating the second water tank 50 from the main body 10 makes it convenient for users to thoroughly clean the second water tank 50.

[0116] In some embodiments, the first water tank 40 can be removed from the side of the body 10.

[0117] The user can directly pull out the first water tank 40 horizontally from the side of the machine body. Specifically, the first water tank 40 is connected to the machine body 10 through a lateral slide rail mechanism, which makes the pulling process smooth and easy for the user to pull out the first water tank 40. In addition, the slide rail mechanism can also support the first water tank 40 to ensure that the first water tank 40 is stably set inside the machine body.

[0118] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
