[0053] In the description of the present application, it needs to be understood that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0054] The air conditioner 200 according to the embodiment of the present application comprises an air conditioner body and an air treatment device 100, the air conditioner body is an indoor unit, for example, a wall-mounted air conditioner or a cabinet air conditioner, the air conditioner body usually comprises a fan wheel, a heat exchanger and the like, the heat exchanger is used for heat exchange of gas flowing therethrough, so as to realize the functions of refrigeration or heating.

[0055] The air treatment device 100 can be used for purifying and humidifying the gas, improving the air quality, air humidity and the like.

[0056] The air treatment device 100 according to the embodiment of the present application comprises a seat body 10, a humidifying box 20, a water tank 30 and a heating piece 40, the humidifying box 20 is arranged on the seat body 10 and has a humidifying cavity 201 and a steam outlet 202, the steam outlet 202 communicates with the humidifying cavity 201, the water tank 30 is used for introducing liquid into the humidifying cavity 201, and the heating piece 40 is arranged in the humidifying cavity 201, and the heating piece 40 is used for heating the liquid in the humidifying cavity 201 to form steam.

[0057] The seat body 10 is the base of the whole device, providing support and fixation for other components. The humidifying box 20 is internally provided with a humidifying cavity 201 for containing liquid. The water tank 30 is used for storing liquid, which can be sent into the humidifying cavity by gravity or pumping. The heating piece 40 heats the liquid in the humidifying cavity. The steam outlet 202 is the outlet of the humidifying cavity for communicating with the outside, through which the heated steam is released into the air.

[0058] Specifically, the liquid in the water tank 30 is transported into the humidifying cavity 201, and the heating piece 40 starts to work to heat the liquid in the humidifying cavity. As the liquid is heated, it gradually turns into steam, which is released into the air through the steam outlet 202, thereby increasing the humidity of the air.

[0059] The air treatment device 100 adopts this steam humidification method, so that the air conditioner 200 has the function of steam humidification. Thus, the steam humidification is used to improve the humidity of indoor air, and the high-temperature heating process can inhibit the growth of bacteria, kill indoor pollutants, and achieve air deposition, which helps to reduce static electricity and dust in the air, thereby achieving precise regulation of indoor air quality and improving user experience. Moreover, this humidification method not only has faster humidification speed and better humidification effect, but also does not need to set a filter, so that the maintenance cost in the later period can be reduced, the frequent cleaning operation can be reduced, and the user experience can be further improved.

[0060] Part of the heating piece 40 extends below the steam outlet 202, ensuring that the liquid is fully heated before it turns into steam, and the steam formed by the heating piece 40 can be directly discharged through the steam outlet 202, to some extent, ensuring the steam temperature and the discharge speed of the steam.

[0061] Further, when the water in the water tank 30 is exhausted and the water level in the humidifying box 20 drops to the lowest water level, the heating piece 40 will stop working. At this time, there is still a part of liquid water remaining in the humidifying cavity 201. If the steam humidification function is not used for a long time after shutdown, the water in the humidifying cavity 201 will remain for a long time, which will breed bacteria and produce odor. When the steam humidification function is used again next time, the residual water and fresh water in the humidifying cavity 201 are mixed again, and the odor of the residual water quickly follows the water vapor into the indoor, which will also bring a very bad experience to the user.

[0062] Therefore, the application provides a solution. The air treatment device 100 further comprises an atomizing device 80, which is arranged in the humidifying cavity 201 and located on one side of the heating piece 40 in the horizontal direction. The atomizing device 80 can be used to atomize the liquid in the humidifying cavity.

[0063] That is, an atomization device 80, such as an ultrasonic humidification structure, is added in the humidification box 20. When the heating element 40 stops working, the atomization device 80 is started to consume the residual water in the humidification cavity 201, thereby preventing the growth of bacteria and odor in the humidification box 20 caused by the residual water, and affecting the user's experience during use.

[0064] Moreover, the humidification box 20 does not need an external drainage pump, which can reduce costs and avoid noise caused by the operation of the drainage pump, and further improve the user's experience.

[0065] In some embodiments of the present application, the humidification box 20 is detachably mounted on the seat body 10. When the humidification box 20 is detached, if a drainage pump or the like is used for drainage, the drainage pipe needs to be detached, which is inconvenient to operate. The present application uses the atomization device 80 arranged in the humidification box 20, which does not need to be connected to the pipe, and when the humidification box 20 is detached, the atomization device 80 can be taken out at the same time, thereby also achieving cleaning, replacement and maintenance of the atomization device 80.

[0066] As shown in Figures 7-9 In some embodiments, the atomization device 80 includes a water absorbing element 81 and an atomization sheet assembly 82. The water absorbing element 81 is arranged in the humidification cavity 201 and is used to absorb the liquid in the humidification cavity 201. The atomization sheet assembly 82 is arranged on the water absorbing element 81, and the atomization sheet assembly 82 can make the water absorbed by the water absorbing element 81 into water mist.

[0067] The atomization sheet assembly 82 can be an ultrasonic atomization sheet. The water is changed into small water bead shape by using ultrasonic principle, thereby producing mist spray. Specifically, the ultrasonic atomization sheet produces high-frequency resonance by electronic high-frequency oscillation (for example, the oscillation frequency is 1.7 MHz or 2.4 MHz, which is beyond the human hearing range, and the electronic oscillation does not harm the human body and animals), which disperses the liquid water molecule structure, and further produces natural and elegant water mist without heating or adding any chemical reagent.

[0068] The installation height of the atomization sheet assembly 82 is higher than the lowest water level controlled by the water level detector, that is, higher than the water level when the atomization sheet assembly 82 starts to work, so as to ensure that the generated atomization steam can be smoothly discharged. When the heating element 40 stops working, the atomization sheet assembly 82 is started, the water absorbing element 81 capillarily transfers the residual water in the humidification cavity 201 to the bottom of the atomization sheet assembly 82, and then the atomization sheet assembly 82 produces water mist by electronic high-frequency oscillation, and further discharges from the steam outlet.

[0069] In addition, after the fan-induced airflow is introduced into the humidification cavity 201, the generated water mist can be accelerated to be discharged, the processing efficiency of the residual water is improved, and the residual water in the humidification cavity 201 is consumed until the atomization device 80 stops working.

[0070] AsFigures 5-9 As shown, in some embodiments, a mounting post 23 is provided in the humidification chamber 201. The middle part of the mounting post 23 defines a mounting groove 231. The mounting post 23 has a liquid outlet 232, which communicates with the mounting groove 231 and extends to the bottom wall of the humidification chamber 201. The atomizing device 80 is installed in the mounting groove 231 and is sealed to the mounting post 23, thereby realizing the installation of the atomizing device 80 in the humidification chamber 201. Moreover, the mounting groove 231 is connected to the humidification chamber 201 through the liquid outlet 232, and the water-absorbing component 81 can absorb the water in the humidification chamber 201 in time and guide the residual water to the atomizing plate assembly 82 for atomization.

[0071] like Figure 7 and Figure 8 As shown, in some embodiments, the mounting column 23 is provided with an annular baffle 233, which is used to divide the mounting groove 231 into a first mounting groove 231a and a second mounting groove 231b arranged vertically. The atomizing plate assembly 82 is installed in the first mounting groove 231a, and the atomizing plate assembly 82 is sealed to the mounting column 23 by a sealing member. The outer periphery of the second mounting groove 231b has a liquid outlet 232, and the annular baffle 233 defines an installation port. The water suction member 81 passes through the installation port, and the outer periphery of the water suction member 81 abuts against the annular baffle 233, thereby fixing the water suction member 81 in the mounting groove 231. The atomizing plate assembly 82 is installed in the first mounting groove 231a, which is convenient for installation and allows the atomizing plate assembly 82 to be fixed at a certain height. The installation height of the atomizing plate assembly 82 is higher than the minimum water level controlled by the water level detector to ensure that the generated atomized steam can be discharged smoothly.

[0072] When using the steam humidification function, the heating element 40 is turned on. If the high-temperature steam only diffuses freely into the external environment, the amount of steam output is limited, which affects the humidification effect. In particular, some humidification boxes 20 output to the external environment through the steam pipe 11. However, it takes a long time for the steam pipe 11 to be filled by free diffusion alone, which affects the user experience. Moreover, it can cause the airflow channels inside the humidification box 20 and water tank 30 to overheat, accelerate the heat deformation and aging of the components, and affect the service life of the device. In addition, the long-term free diffusion will also make it difficult for the generated steam to be discharged, which can easily lead to condensation and backflow, greatly reducing the amount of steam delivered to the outside.

[0073] Among them, the steam transmission pipe 11 is made of a material with certain heat insulation function to reduce the amount of cooling during steam transmission and to deliver more hot steam into the room to a greater extent.

[0074] like Figures 1-4 As shown, in some embodiments, the air handling device 100 further includes a fan 50 having an air outlet duct.

[0075] In some examples, the fan 50 has a flow guide outlet 52 located in the air outlet duct, the humidifying box 20 has a air guide inlet 203 which is in communication with the humidifying cavity 201, the air guide inlet 203 is in communication with the flow guide outlet 52, so that the air in the air outlet duct can enter the humidifying cavity 201 through the air guide inlet 203, for example, the air guide inlet 203 is in communication with the flow guide outlet 52 through the air guide pipe 16, and the fan 50 can guide the air entering the fan inlet 51 to enter the humidifying cavity 201 through the air guide inlet 203 and the air guide pipe 16.

[0076] Therefore, by arranging the flow guide outlet 52 on the fan 50, using the fan 50 and adopting a separate air flow branch input, the humidifying cavity 201 is blown, and the high-temperature steam is discharged from the humidifying cavity 201 faster; in addition, when the steam humidifying function is not used, the humidifying cavity 201 can be dried to prevent bacterial growth.

[0077] In addition, by introducing the air flow branch, when the atomizing device 80 is working, the water mist discharge rate can be accelerated, and the water adhering to the inner wall of the humidifying box 20 can be dried faster to prevent bacterial growth.

[0078] The air outlet duct has a fan outlet 53 which can be in communication with the indoor or outdoor environment to discharge the air accelerated by the fan 50 to the indoor or outdoor environment.

[0079] The air treatment device 100 of the air conditioner 200 generally has a function of introducing fresh air, that is, has a fresh air fan, and can also have a function of discharging indoor dirty air, that is, has an exhaust fan, the fan 50 here can be an exhaust fan or a fresh air fan, and of course can be a separate fan.

[0080] That is, without increasing additional air flow driving devices, the existing fresh air fan in the air conditioner 200 is used to realize rapid steam discharge, accelerate the steam ejection rate and the mixing amount with the indoor circulating air, and the humidifying rate is faster; on the other hand, the air flow introduced from the fan 50 can realize the drying of the humidifying cavity 201, reduce the bacterial growth, and maintain a relatively clean steam generation environment.

[0081] In some specific examples, the air treatment device 100 has an exhaust fan and a fresh air fan which are axially the same and arranged side by side, and the two fans can be driven by a motor to rotate two impellers, the flow guide outlet 52 can be located on the air outlet duct of the exhaust fan, and by using the exhaust fan to guide the flow, the air volume of the fresh air will not be affected, and the user's experience is ensured.

[0082] In some embodiments, the atomizing device 80 is located below the air inlet 203, so that the air flow entering the humidifying cavity 201 through the air inlet 203 can directly flow through the atomizing device 80, thereby taking away the water mist generated by the atomizing device 80, accelerating the rate of water mist discharge, and more quickly blowing off the moisture adhered to the inner wall of the humidifying box 20 to prevent bacterial growth.

[0083] As shown in Figure 4 , Figures 10-13 In some embodiments, the fan 50 has a fan outlet 53 located at one end of the air outlet duct, and the air guide outlet 52 is located at the other end of the air outlet duct. The fan outlet 53 can be in communication with the indoor or outdoor environment, that is, the air guide outlet 52 and the fan outlet 53 can be located at the two ends of the air outlet duct. Thus, the air flow accelerated by the fan 50 can be partially blown into the humidifying cavity 201 through the air guide outlet 52, and the other part is discharged through the fan outlet 53. That is, the fan 50 can simultaneously accelerate the discharge of steam and discharge the accelerated air flow through the fan outlet 53, thereby fully utilizing the fan 50 in the air conditioner 200 and not needing to additionally set a separate fan 50 for blowing air into the humidifying cavity 201.

[0084] According to the air treatment device 100 of the embodiments of the present application, a branch is led from the air outlet duct of the fan 50 to blow part of the air flow into the humidifying box 20. On the one hand, the generated steam can be quickly discharged, the residence time of the steam in the humidifying cavity 201 is reduced, the deformation of the components due to the excessive temperature rise in the humidifying cavity 201 is avoided, the steam can be more quickly discharged through the steam discharge pipe 11, the condensation amount of the steam is reduced, and the amount of steam discharge is greater. On the other hand, when the steam humidification function is not used for a long time, the air flow blown into the humidifying box 20 can be used to dry the humidifying cavity 201 to prevent bacterial growth in the humidifying cavity 201 and create a clean environment for the next use of the steam generation function.

[0085] In some embodiments, the fan 50 is provided with a movable baffle. The movable baffle (not shown in the figure) is arranged in the air outlet duct. The movable baffle can be switched between the positions of opening and closing the air guide outlet 52. For example, the movable baffle is rotationally connected with the fan shell. By rotating the movable baffle, the air guide outlet 52 can be opened, and part of the air flow in the air outlet duct can enter the humidifying box 20 through the air guide pipe 16 and the air inlet 203. By rotating the movable baffle, the air guide outlet 52 can be closed, and the air flow in the air outlet duct will not enter the humidifying box 20.

[0086] As shown in Figures 10-13As shown, in some embodiments, the fan outlet 53 comprises an outdoor exhaust port 531 and an indoor circulation port 532, the outdoor exhaust port 531 is in communication with the outdoor, and the indoor circulation port 532 is in communication with the indoor, and the fan outlet is provided with a movable shielding piece 54, which is used to open one of the outdoor exhaust port 531 and the indoor circulation port 532, that is, the shielding piece 54 can shield the outdoor exhaust port 531 and open the indoor circulation port 532, or the shielding piece 54 can shield the indoor circulation port 532 and open the outdoor exhaust port 531.

[0087] For example, when the heating element 40 is working, the movable baffle is moved to a position to open the drainage outlet 52, and the shielding piece 54 is moved to a position to shield the outdoor exhaust port 531, at this time the indoor circulation port 532 is opened, part of the air in the fan outlet is introduced into the humidifying box 20, the speed of steam exhaust is improved, and the steam humidifying effect is improved.

[0088] For another example, after the heating element 40 stops working, the atomizing device 80 is started, the residual water in the water humidifying cavity 201 is consumed, and at the same time the shielding piece 54 in the fan outlet is moved to a position to shield the outdoor exhaust port 531, at this time the indoor circulation port 532 is opened, part of the air in the fan outlet is introduced into the humidifying box 20, the water adhered to the inner wall is blown dry, and bacteria breeding is prevented.

[0089] As shown, Figure 10 As shown, in some embodiments, the air treatment device 100 also has a steam output port 102 for outputting steam, and the steam outlet 202 is in communication with the steam output port 102, for example, connected through the steam pipe 11, so that the steam formed after the heating element 40 is heated can be discharged to the indoor through the steam outlet 202 and the steam output port 102.

[0090] In some embodiments, the steam output port 102 is adjacent to the indoor circulation port 532, and the steam output port 102 can be located above the indoor circulation port 532, so that the negative pressure formed at the steam output port 102 by the airflow of the fan 50 can quickly draw steam out of the steam pipe 11.

[0091] The high-speed airflow at the indoor circulation port 532 can cause a negative pressure area to be formed in the area before the outlet, due to the existence of pressure difference, atmospheric pressure pushes the surrounding air to the outlet area, thereby driving the high-temperature water vapor to be quickly discharged from the steam output port 102, at this time, it is equivalent to steam being extracted from the steam pipe 11, greatly reducing the residence time of steam in the steam pipe 11.

[0092] In some embodiments, the steam outlet 102 is adjacent to the indoor circulating air outlet 532, and the steam outlet 102 is located below the indoor circulating air outlet 532. Since steam has a tendency to move upward, the indoor circulating air outlet 532 is arranged above the indoor circulating air outlet 532. The steam is mixed into the airflow flowing out of the indoor circulating air outlet 532, so that it can be discharged into the room along with the airflow, thereby improving the steam output effect.

[0093] In some specific examples, when the fan 50 is running, a part of the airflow enters the humidifying box 20 through the air guide pipe 16, and the high-temperature water vapor generated in the humidifying box 20 is blown into the steam conveying pipe 11. When the user does not have a humidification requirement for a long time without starting the steam humidification function (for example, the water tank is not refilled for more than t1 time, t1 can be 48h), the movable baffle moves to the position of opening the drainage outlet 52, the shielding piece 54 moves to the position of shielding the outdoor air outlet 531, the indoor circulating air outlet 532 is opened, and part of the airflow is introduced into the humidifying box 20 to accelerate the evaporation of the water vapor attached to the inner wall of the humidifying box 20, so that the inside of the humidifying box 20 maintains a dry environment. After a certain period of time, for example, after 1 hour, the movable baffle moves to the position of closing the drainage outlet 52, and the air blowing into the humidifying box 20 is stopped.

[0094] As shown in Figures 10-13 In some embodiments, the fan outlet 53 is provided with an adapter structure 60, and the adapter structure 60 includes a first adapter 61 and a second adapter 62. The first adapter 61 defines a first adapter channel 611, and the first adapter channel 611 has a steam inlet 612 in communication with the steam outlet 202. The second adapter 62 defines a second adapter channel 621, and one side of the second adapter channel 621 is in communication with the first adapter channel 611, and the other side of the second adapter channel 621 is in communication with the steam outlet 102. In the direction close to the steam outlet 102, the maximum cross-sectional dimension of the first adapter channel 611 is greater than the maximum cross-sectional dimension of the second adapter channel 621. Therefore, the high-temperature steam flowing into the adapter structure 60 has a cross-section that narrows from wide to narrow, and the steam flow rate increases, thereby increasing the distance of steam injection.

[0095] In addition, the high-speed airflow at the indoor circulating air outlet 532 can form a negative pressure area in the area before the outlet. Due to the existence of pressure difference, atmospheric pressure pushes the surrounding air to the outlet area, thereby driving the high-temperature water vapor to be quickly discharged from the steam outlet 102. At this time, it is equivalent to extracting steam from the steam conveying pipe 11, which greatly reduces the residence time of the steam in the steam conveying pipe 11.

[0096] In some embodiments, the first adapter 61 is a circular pipe, and the second adapter 62 is a flat pipe located on one side of the circular pipe in the radial direction. The flat pipe is connected with the circular pipe, and the thickness of the flat pipe is less than the diameter of the circular pipe. Therefore, it is convenient to form a variable cross-section structure, and it is also convenient to manufacture the adapter structure 60.

[0097] In some embodiments, the first adapter channel 611 gradually extends upward in a direction away from the steam inlet 612, thereby facilitating the backflow of condensed water formed at the steam outlet 102, so that the condensed water generated in the adapter structure 60 can flow to the steam inlet 612, and then flow to the humidifying box 20 along the steam pipe 11, the condensed water can be heated again to form steam, while preventing the phenomenon of water spraying at the outlet.

[0098] In some embodiments, the steam outlet 202 is in communication with the steam outlet 102 through the steam pipe 11, the steam pipe 11 is detachably connected with the humidifying box 20, and the steam pipe 11 is detachably connected with the fan 50, so that the humidifying box 20 and the steam pipe 11 can be detached from the air conditioner 200, facilitating cleaning and maintenance.

[0099] As shown in Figure 2 and Figure 3 In some embodiments, one end of the steam pipe 11 is provided with a butt joint 111, and the humidifying box 20 is provided with a steam outlet boss 24, the steam outlet boss 24 defining the steam outlet 202, the butt joint 111 can be inserted into the steam outlet boss 24, and the outer periphery of the butt joint 111 is in sealing cooperation with the steam outlet boss 24, thereby improving the sealing performance of the connection between the steam pipe 11 and the humidifying box 20, and reducing the probability of steam leakage.

[0100] As shown in Figure 2 In some embodiments, the air inlet 203 is in communication with the air outlet 52 through the air pipe 16, the air pipe 16 is detachably connected with the humidifying box 20, and the air pipe 16 is detachably connected with the fan 50, so that the humidifying box 20 and the air pipe 16 can be detached from the air conditioner 200, facilitating cleaning and maintenance.

[0101] As shown in Figure 3 In some embodiments, the humidifying box 20 is provided with an air inlet boss 25, the air inlet boss 25 defining the air inlet 203, and the air pipe 16 is in plug-in cooperation with the air inlet boss 25, thereby facilitating installation and facilitating the assembly and disassembly of the humidifying box 20.

[0102] Specifically, when the humidifying box 20 needs to be detached, the steam pipe 11 and the air pipe 16 are first pulled out of the humidifying box 20, so as to prevent the steam pipe 11 and the air pipe 16 from being directly connected with the humidifying box 20, thereby hindering the pulling action.

[0103] As shown in Figure 9As shown, in some embodiments, the humidifying box 20 comprises a box body 21 and a cover body 22, the box body 21 is provided with a humidifying cavity 201; the cover body 22 is arranged on the box body 21, and the cover body 22 is detachably connected with the box body 21; the heating element 40 is arranged on the cover body 22, and the heating element 40 can be separated from the box body 21 along with the cover body 22, so as to facilitate cleaning of the box body 21 and cleaning of the heating element 40.

[0104] For example, the heating element 40 can be fixed on the cover body 22 of the humidifying box 20 by screws, and the user can directly manually clean the scale on the surface of the heating element 40 by lifting the cover body 22.

[0105] In the upper installation mode of the heating element 40, the problem of air leakage or water leakage due to poor sealing or aging of the sealing ring after long-term operation of the heating element 40 installed at the bottom can be effectively prevented.

[0106] As shown in the drawings, Figure 1 As shown, the humidifying box 20 and the water tank 30 are located on the front side of the fan 50 as a whole, and the water tank 30 is located on the upper portion of the humidifying box 20, so as to fully utilize the space on the front side of the fan 50.

[0107] The cover body 22 is provided with the heating element 40 and the water level detector, a sealing strip is arranged between the cover body 22 and the box body 21, the cover body 22 and the box body 21 can be fixed by buckling and are convenient to detach; meanwhile, the cover body is provided with a steam outlet 202 and an air inlet 203, the steam outlet 202 is connected with the steam conveying pipe 11, and the other end of the steam conveying pipe 11 is connected with the steam outlet 102.

[0108] The air inlet 203 is connected with the air guiding outlet 52 of the fan 50 through the air guiding pipe 16, and when the fan 50 operates, part of the airflow enters the humidifying cavity 201 through the air guiding pipe 16, and the high-temperature water vapor generated in the humidifying cavity 201 is blown into the steam conveying pipe 11.

[0109] As shown in the drawings, Figure 9 As shown, in some examples, the humidifying box 20 is provided with a partition plate 211, for example, the partition plate 211 is arranged in the box body 21, the partition plate 211 is used for dividing the humidifying cavity 201 into a first cavity 2011 and a second cavity 2012, the first cavity 2011 is open at the top, the partition plate 211 is provided with a communication port 212, the communication port 212 can communicate the first cavity 2011 and the second cavity 2012, the cover body 22 is arranged on the second cavity 2012 and is used for sealing the second cavity 2012, and it should be noted that the length of the second cavity 2012 is greater than the maximum length of the heating element 40, so that when the cover body 22 covers the second cavity 2012, the heating element 40 can be placed in the second cavity 2012.

[0110] The first chamber 2011 has a top column 213 that cooperates with the water tank 30. The top column 213 is used to open the water outlet valve at the bottom of the water tank 30, so that the water in the water tank 30 flows into the first chamber 2011. The first chamber 2011 and the second chamber 2012 are interconnected, and the water in the water tank 30 can flow into the second chamber 2012.

[0111] Specifically, the top column 213 contacts the water outlet valve at the bottom of the water tank 30, and the water inside the water tank 30 flows into the humidification box 20. When the water in the humidification box 20 is submerged by the water outlet valve, the water tank 30 and the humidification box 20 form a communicating vessel. At this time, the water level in the humidification box 20 will not change and will always remain submerged by the water outlet valve. When the water in the humidification box 20 is heated by the heating element to generate high-temperature water vapor, the water in the humidification box 20 is consumed, and the water tank 30 simultaneously replenishes water to the humidification box 20 to maintain a constant water level in the humidification box 20.

[0112] like Figures 5-9 As shown, in some embodiments, the atomizing device 80 is installed in the second chamber 2012, thereby the atomizing device 80 can be adjacent to the heating element 40 and the steam outlet 202, and the water mist formed by the atomizing device 80 can be discharged in time through the steam outlet 202.

[0113] like Figures 1-9 As shown, in some embodiments, the humidifier box 20 is detachably connected to the base 10. The base 10 defines an installation cavity 101, and the humidifier box 20 is detachably disposed in the installation cavity 101. For example, a limiting structure is provided on the base 10, which can be a snap-fit, slot, guide rail, etc. This enables the humidifier box 20 to be detachable. After the humidifier box 20 is disassembled, the inside of the humidifier box 20 and the heating element 40 can be cleaned. This solves the pain point that the traditional heating element is sealed inside the humidification cavity, making disassembly inconvenient and unable to be thoroughly cleaned. Users can more intuitively observe and handle the dirt on the heating element 40.

[0114] In some embodiments, the air handling device 100 further includes a water level detector, which is disposed on the humidification box 20. A portion of the water level detector extends into the humidification chamber 201 to detect the water level in the humidification chamber 201. The water level detector can control the operation of the heating element 40 according to the detected water level. By setting the water level detector, the heating element 40 is prevented from being damaged due to prolonged dry burning.

[0115] The water level detector can be made up of two electrode rods, one long and one short. The two electrode rods form an electrical path in the humidification chamber 201, thereby realizing the monitoring of the water level.

[0116] In some embodiments, the heating element 40 is adapted to work when the water level is not lower than the lowest water level controlled by the water level detector, the atomizing piece assembly 82 is adapted to work when the water level is lower than the lowest water level controlled by the water level detector, and the height of the atomizing piece assembly 82 is higher than the lowest water level controlled by the water level detector.

[0117] The water level detector is used to detect the water level in the water tank, and after the water in the water tank 30 is consumed, the heating element 40 continues to work to consume water. When the water level in the humidifying cavity 201 is lower than the lowest position of the water level detector, the power supply of the heating element 40 is cut off to prevent the heating element 40 from dry burning and causing a safety hazard.

By adopting the air treatment device 100, the air conditioner 200 has the function of steam humidification, improves the humidity of indoor air by using steam humidification, and can inhibit bacterial growth in the process of high-temperature heating, kill indoor pollutants, and realize air precipitation, which helps to reduce static electricity and dust in the air, thereby realizing accurate regulation and control of indoor air quality and improving the use experience of users. Moreover, the humidification method has the advantages of faster humidification speed, better humidification effect, and no need to set a filter, so that the maintenance cost in the later period can be reduced, the operation of frequent cleaning can be reduced, and the use experience is further improved.

[0119] In some embodiments, the air conditioner 200 includes a housing, a part of the housing forms the seat body 10 of the air treatment device 100, the humidifying box 20 is arranged at the bottom of the air conditioner 200, and the water tank 30 can also be arranged at the bottom of the air conditioner 200, so that the humidifying box 20 and the water tank 30 are convenient to disassemble and install.
