[0037] The principles and features of this application are described below with reference to the accompanying drawings. The examples given are only for explaining this application and are not intended to limit the scope of this application.

[0038] like Figures 1 to 13As shown in the figure, this application provides a humidification device, including a heating water tank 1 and a heater 2.

[0039] The upper part of the heating water tank 1 is provided with an installation port 13. The heater 2 includes a wiring part 21 and a heating part 22 connected to the wiring part 21. The wiring part 21 is at least partially located outside the heating water tank 1 and covers the installation port 13, and is configured to be electrically connected to the power supply module. The heating part 22 is configured to pass through the installation port 13 and be inserted into the heating water tank 1, and is configured to heat the water in the heating water tank 1 so that the heating water tank 1 can output steam.

[0040] The humidification device provided in this embodiment uses a heater 2 to heat water to generate steam to meet humidification needs, eliminating the problem of bacterial growth and ensuring high cleanliness. Furthermore, compared to designs where the heater 2 is inserted upwards from the bottom of the water tank 1 or horizontally from the side of the water tank 1, this design inserts the heater 2 downwards from the top of the water tank 1. This prevents water in the water tank 1 from easily reaching the installation port 13, thus reducing the likelihood of leakage.

[0041] The heater 2 can be one or more. Correspondingly, the mounting port 13 can be one or more.

[0042] In some exemplary embodiments, such as Figures 2 to 6 As shown, the upper part of the heating water tank 1 includes a horizontally arranged first mounting surface 11, and the mounting port 13 is provided on the first mounting surface 11 so that the heating part 22 can be inserted into the heating water tank 1 in a vertical direction.

[0043] In this design, the structure of the heating water tank 1 is relatively simple and regular, which is convenient for both processing and molding, as well as for the installation of the heater 2.

[0044] In some embodiments, such as Figure 7 As shown, the distance C1 between the lower end of the heating part 22 and the inner bottom wall of the heating water tank 1 can be, but is not limited to, greater than or equal to 10 mm. This helps to prevent the heater 2 from directly heating the inner bottom wall of the heating water tank 1, which would cause the heating water tank 1 to deform or soften and affect its strength.

[0045] In some embodiments, the heating element 22 is configured as a columnar structure (e.g., a cylindrical or prismatic structure), with its lower end below the set maximum liquid level of the heating water tank 1, to ensure that the heating element 22 can contact the water and thus heat it. A rated water level line can be provided inside the heating water tank 1, and the set maximum liquid level is the liquid level that is flush with the rated water level line.

[0046] like Figure 7As shown, the length of the heating element 22 is denoted as B1, the liquid level of the set maximum liquid level in the heating water tank 1 is denoted as E1, and the distance between the lower end of the heating element 22 and the set maximum liquid level is denoted as D1, where D1 / B1≤0.9 and E1 / B1≤0.8. D1 is the length of the heating element 22 inserted below the liquid surface.

[0047] This design helps to avoid the liquid level in the heating water tank 1 being too high or the distance between the liquid surface and the installation port 13 being too small, so that part of the heating part 22 can be located above the set maximum liquid level, thereby reducing the risk of water leakage at the installation port 13.

[0048] Of course, the shape and size of the heating element 22 are not limited to the above-described scheme and can be adjusted as needed. The heating element 22 can be a cylindrical structure, and the diameter of the heating element 22 is denoted as A1. The sizes of A1 and B1 are not limited and can be reasonably set as needed.

[0049] In one embodiment, such as Figures 2 to 6 As shown, there are four mounting ports 13, arranged in an array. Correspondingly, there are four heaters 2, with each heater 2 corresponding to one of the four mounting ports 13.

[0050] In other exemplary embodiments, such as Figures 8 to 12 As shown, the upper part of the heating water tank 1 includes a second mounting surface 12 that is inclined, and a mounting port 13 is provided on the second mounting surface 12 so that the heating part 22 can be inserted into the heating water tank 1 in an inclined direction.

[0051] Compared to the vertical insertion of the heating element 22, the inclined design of this solution is beneficial to increasing the area of ​​the heating element 22 inserted below the water surface, thereby improving the heating efficiency of the heater 2 on the water.

[0052] In some embodiments, such as Figure 13 As shown, the distance C2 between the center of the lower end face of the heating part 22 and the inner bottom wall of the heating water tank 1 can be, but is not limited to, greater than or equal to 10 mm. This helps to prevent the heater 2 from directly heating the inner bottom wall of the heating water tank 1, which would cause the heating water tank 1 to deform or soften and affect its strength.

[0053] In some embodiments, the heating element 22 is configured as a columnar structure (e.g., a cylindrical or prismatic structure), with its lower end face lower than the set maximum liquid level of the heating water tank 1, to ensure that the heating element 22 can contact the water and thus heat it. A rated water level line can be provided inside the heating water tank 1, and the set maximum liquid level is the liquid level that is flush with the rated water level line.

[0054] like Figure 13As shown, the length of the heating part 22 is denoted as B2, the liquid level height of the set maximum liquid level of the heating water tank 1 is denoted as E2, the intersection of the central axis of the heating part 22 and the set maximum liquid level is denoted as O, the distance between O and the lower end face of the heating part 22 is denoted as D2, the angle between the heating part 22 and the vertical direction is denoted as θ, D2 / B2≤0.9, E2 / ≤0.8×B2×cosθ.

[0055] This design helps to avoid the liquid level in the heating water tank 1 being too high or the distance between the liquid surface and the installation port 13 being too small, so that part of the heating part 22 can be located above the set maximum liquid level, thereby reducing the risk of water leakage at the installation port 13.

[0056] Of course, the shape and size of the heating element 22 are not limited to the above-described scheme and can be adjusted as needed. The heating element 22 can be a cylindrical structure, and the diameter of the heating element 22 is denoted as A2. The sizes of A2 and B2 are not limited and can be reasonably set as needed.

[0057] In some embodiments, the angle θ between the heating part 22 and the vertical direction satisfies: 30°≤θ<90°, such as 30°, 45°, 60°, 75°, 85°, etc.

[0058] Of course, the angle θ between the heating part 22 and the vertical direction is not limited to the above range and can be adjusted as needed.

[0059] In one embodiment, such as Figures 8 to 12 As shown, the heating water tank 1 is symmetrically provided with two second mounting surfaces 12, each of which has two mounting ports 13, and the mounting ports 13 on the two second mounting surfaces 12 are staggered. Correspondingly, there are four heaters 2, with each of the four heaters 2 corresponding to one of the four mounting ports 13.

[0060] In some exemplary embodiments, such as Figures 14 to 16 As shown, the heating part 22 includes a heat-conducting outer shell 221 and a heating element 222 disposed inside the heat-conducting outer shell 221. The heating element 222 is electrically connected to the wiring part 21.

[0061] The thermally conductive housing 221 may include a thermally conductive shell (not shown in the figure) and a thermally conductive insulating layer (not shown in the figure), with the thermally conductive insulating layer located between the thermally conductive shell and the heating element 222. The thermally conductive shell may be, but is not limited to, a metal shell. The thermally conductive insulating layer can prevent leakage current, which helps to improve the safety of the humidification device.

[0062] In some embodiments, the heating element 222 is an integral structure. An integral structure is powered on and off together, which simplifies the electrical control program; and its integrated installation simplifies the assembly process. The heating element 222 can be a uniform heating element 222.

[0063] In some embodiments, the heating element 222 is an integral structure, and the heat-conducting outer shell 221 is provided with a dense area 2213 and an empty area 2214, such as Figure 14 As shown, the dense area 2213 is located below the empty area 2214, and the heating element 222 is located in the dense area 2213.

[0064] Since the vacant zone 2214 lacks a heating element 222, its heating capacity is relatively low, relying solely on heat transfer from the dense zone 2213 for heating. However, since the vacant zone 2214 is at least partially above the liquid surface and does not contact the water, it can only heat the air, contributing little to steam generation. Therefore, the design of the vacant zone 2214 helps save energy.

[0065] In some examples, the length of the dense region 2213 can be greater than the length of the vacant region 2214, such as... Figure 14 As shown, this is beneficial to improving the overall heating power of the heating element 222, thereby ensuring the steam generation efficiency.

[0066] In some embodiments, the heating element 222 is an integral structure. The heat-conducting outer shell 221 is provided with a dense area 2213 and a evacuation area 2215, such as... Figure 15 As shown, the dense area 2213 is located below the evacuation area 2215. The heating element 222 includes a first heating section 2221 and a second heating section 2222, as shown. Figure 15 As shown, the first heating section 2221 is located in the dense area 2213, and the second heating section 2222 is located in the evacuation area 2215. The heating power of the first heating section 2221 is greater than that of the second heating section 2222.

[0067] Since the evacuation zone 2215 is at least partially located above the liquid surface and does not come into contact with water, it can only heat the air and contributes relatively little to steam generation. Therefore, the heating power of the second heating section 2222 of the evacuation zone 2215 can be lower, which is beneficial for saving energy.

[0068] For example, heating element 222 is a PTC heating element 222. The PTC ceramic plates in the first heating section 2221 can be densely arranged to increase the heating power; the PTC ceramic plates in the second heating section 2222 can be sparsely arranged to reduce the heating power.

[0069] In some examples, such as Figure 15 As shown, the length of the dense zone 2213 can be greater than the length of the evacuation zone 2215, which is beneficial to improving the overall heating power of the heating element 222 and thus ensuring the steam generation efficiency.

[0070] In some other exemplary embodiments, the heating element 222 has a split structure, comprising a first sub-heating element 2223 and a second sub-heating element 2224 that are independent of each other, such as Figure 16 As shown. The wiring section 21 includes a first sub-wiring section and a second sub-wiring section that are independent of each other, as shown. Figure 16 As shown, the first sub-connection section is electrically connected to the first sub-heater 2223, and the second sub-connection section is electrically connected to the second sub-heater 2224. In this way, the first sub-heater 2223 and the second sub-heater 2224 can be controlled separately and independently, facilitating the rational control of the heating power of the heater 2 based on the liquid level in the heating water tank 1. This helps reduce energy consumption while ensuring that humidification requirements are met.

[0071] The first sub-heater 2223 is located below the second sub-heater 2224, and the heating power of the first sub-heater 2223 is greater than the heating power of the second sub-heater 2224.

[0072] Since the upper part of the heating element 222 is located above the liquid surface and does not contact the water, it can only heat the air and contributes relatively little to steam generation. Therefore, the heating power of the second sub-heater 2224 located on the upper side can be smaller, which is beneficial to saving energy.

[0073] For example, heating element 222 is a PTC heating element 222. The PTC ceramic plates of the first sub-heating element 2223 can be densely arranged to increase the heating power; the PTC ceramic plates of the second sub-heating element 2224 can be arranged more sparsely to reduce the heating power.

[0074] In some examples, the length of the first sub-heater 2223 can be greater than the length of the second sub-heater 2224, such as... Figure 16 As shown, this is beneficial to improving the overall heating power of heater 2, thereby ensuring steam generation efficiency.

[0075] In some exemplary embodiments, the wiring portion 21 includes an end cap 211 and a wire body 212, such as Figure 3 As shown, end cap 211 covers the mounting port 13 and supports the heating element 22. Line 212 is connected to the heating element 22 and is configured to connect to the power supply module. End cap 211 can be a flange cover. End cap 211 can be threadedly connected to the heating water tank 1.

[0076] Among them, since the heating element 222 is an integral structure, the wire 212 is electrically connected to the heating element 222, such as Figure 14 and Figure 15 As shown.

[0077] Since the heating element 222 has a split structure, the wire body 212 includes a first wire body 2121 and a second wire body 2122 that are independent of each other, such as Figure 16 As shown, the first wire body 2121 forms the first sub-connection portion, and the second wire body 2122 forms the second sub-connection portion. The first wire body 2121 and the second wire body 2122 can be inserted into the same end cap 211.

[0078] In some exemplary embodiments, such as Figure 1 As shown, the humidifier also includes a water supply module, which is configured to supply water to the heating water tank 1. This enables automatic water supply to the humidifier, eliminating the need for manual water supply by the user, thus improving the intelligence of the humidifier and enhancing the user experience.

[0079] In some embodiments, such as Figure 1 As shown, the heating water tank 1 is provided with a water inlet 14. The water supply module includes a water storage tank 3, a water inlet pipe 31, and a first water inlet valve 32. The water storage tank 3 is connected to the water inlet 14 of the heating water tank 1 through the water inlet pipe 31. The first water inlet valve 32 is located on the water inlet pipe 31 and is configured to control the opening and closing of the water inlet pipe 31.

[0080] In some embodiments, such as Figure 1 As shown, the humidification device also includes: a water inlet path 36 and a second water inlet valve 37. The humidification device may also include a pressure regulating valve 38.

[0081] The water inlet path 36 is configured to connect the water storage tank 3 with an external water source, and is configured to supply water to the water storage tank 3. The water supplied by the external water source can be tap water or purified water.

[0082] The second inlet valve 37 and the pressure regulating valve 38 are located in the inlet flow path 36. The second inlet valve 37 is configured to control the opening and closing of the inlet flow path 36. The pressure regulating valve 38 is configured to stabilize the water pressure in the inlet flow path 36, so as to prevent excessive water pressure from affecting the normal operation of the inlet flow path 36 and subsequent components.

[0083] In some embodiments, such as Figure 1 As shown, the humidification device also includes a mechanical water level control switch 34 and a high / low water level control switch 33. The high / low water level control switch 33 is configured to control the automatic opening and closing of the second water inlet valve 37, so that the water level in the water storage tank 3 can be maintained between the set minimum and maximum water levels. The mechanical water level control switch 34 can function as a water level switch in the event of failure of the high / low water level control switch 33, achieving double protection.

[0084] In some embodiments, such as Figure 1 As shown, the humidification device also includes a temperature sensor 35, which is located inside the water storage tank 3 and is used to detect the water temperature inside the water storage tank 3.

[0085] In some embodiments, such as Figure 1 As shown, the humidification device also includes a humidity sensor 6, configured to detect the humidity of the space to be humidified.

[0086] In some embodiments, such as Figure 1As shown, the humidification device also includes a liquid level sensor 17, which is located inside the heating water tank 1 and is configured to detect the liquid level height inside the heating water tank 1.

[0087] In some exemplary embodiments, such as Figure 1 As shown, the heating water tank 1 is provided with a steam outlet 16, and the humidification device also includes a steam pipeline 5 and a steam control valve 51. The steam pipeline 5 is connected to the steam outlet 16, and the steam outlet 16 is connected to the space to be humidified through the steam pipeline 5. The steam control valve 51 is located in the steam pipeline 5 and is configured to control the on / off connection between the steam outlet 16 and the space to be humidified.

[0088] In this way, by controlling the connection and disconnection between the space to be humidified and the steam outlet 16 through the steam control valve 51, the humidifier can be controlled to humidify or stop humidifying the space to be humidified, thereby realizing automatic humidification of the humidifier and improving the user experience.

[0089] In some exemplary embodiments, such as Figure 1 As shown, the heating water tank 1 is provided with a drain outlet 15. The humidification device also includes: a water receiving tray 4, a drain pipe 41, and a drain control valve 42. The water receiving tray 4 is located on the lower side of the heating water tank 1, and the water receiving tray 4 is connected to the drain outlet 15 through the drain pipe 41. The drain control valve 42 is located on the drain pipe 41 and is configured to control the on / off connection between the drain outlet 15 and the water receiving tray 4.

[0090] In this way, by controlling the flow between the water receiving pan 4 and the drain outlet 15 through the drain control valve 42, the water tank 1 can be controlled to drain water into the water receiving pan 4 or stop draining, thereby realizing automatic drainage of the water tank 1 without the need for manual drainage by the user, which is beneficial to improving the user experience.

[0091] This application also provides an air treatment device (not shown in the figure), which includes the humidification device of any of the above embodiments, and thus has all the above-mentioned beneficial effects, which will not be repeated here.

[0092] Air handling equipment can be air conditioners, air purifiers, sterilizers, and other devices with air handling functions.

[0093] When the air handling unit is an air conditioner, it can be a split-type air conditioner, in which case the humidifier is connected to the indoor unit of the split-type air conditioner. Alternatively, it can be an integrated air conditioner.

[0094] The main body of the air handling equipment may be equipped with a humidification port, and the steam outlet 16 of the humidification device is connected to the humidification port.

[0095] This application also provides a control method applicable to the humidification device in any of the above embodiments. For example... Figure 17 As shown, the control methods include:

[0096] Step S202: Obtain the current humidity, target humidity, and liquid level in the heating water tank 1 of the target space to be humidified;

[0097] Step S204: Control heater 2 based on current humidity, target humidity and liquid level.

[0098] The control method provided in this application uses a heater 2 to heat water to generate steam to meet humidification requirements, eliminating the problem of bacterial growth and ensuring high cleanliness. Furthermore, compared to methods where the heater 2 is inserted upwards from the bottom of the water tank 1 or horizontally from the side of the water tank 1, this method inserts the heater 2 downwards from the top of the water tank 1. This prevents water in the water tank 1 from easily reaching the installation port 13, thus reducing the likelihood of leakage.

[0099] The target humidity can be obtained through external input. For example, users can input the target humidity via remote control, mobile terminal (such as mobile phone, computer, iPad, or smart band) APP, or the machine's control panel.

[0100] Alternatively, the target humidity can be determined using internally stored information. For example, the target humidity can be a pre-set target humidity at the factory, or a target humidity previously set by the user.

[0101] In some exemplary embodiments, the heating element 222 of the heating section 22 is an integral structure, such as... Figure 14 and Figure 15 As shown. The heating element 222 can be a uniform, monolithic structure that fills the entire heat-conducting outer shell 221. Alternatively, the heating element 222 can be a uniform, monolithic structure, but only located in the dense area 2213 of the heat-conducting outer shell 221. Alternatively, the heating element 222 can include a first heating segment 2221 and a second heating segment 2222, with the first heating segment 2221 located in the dense area 2213 and the second heating segment 2222 located in the dispersed area 2215, and the heating power of the first heating segment 2221 being greater than the heating power of the second heating segment 2222.

[0102] like Figure 18 As shown, heater 2 is controlled based on the current humidity, target humidity, and liquid level, including:

[0103] The heater 2 is controlled to operate based on the liquid level in the heating water tank 1 being within a set height range.

[0104] Once the target humidity is reached in the target space, heater 2 is turned off.

[0105] When the liquid level in the heating water tank 1 is within the set height range, it indicates that the water volume in the heating water tank 1 is sufficient. At this time, the heater 2 will operate without dry burning, and the heating element 22 can be fully immersed in the water, which helps to improve humidification efficiency. When the current humidity of the target space to be humidified reaches the target humidity, it indicates that the humidification requirement has been met, so the heater 2 is turned off.

[0106] The set height range can be, but is not limited to, h1-△h≤h≤h1+△h, where h is the actual liquid level height, h1 is the set liquid level height threshold, and △h is the liquid level height fluctuation difference. The values ​​of h1 and △h are not limited and can be determined as needed.

[0107] The target humidity level is reached when the current humidity of the space to be humidified reaches the target humidity level, including: the current humidity d of the target space to be humidified satisfies d1 - Δd ≤ d ≤ d1 + Δd, where d1 is the target humidity and Δd is the humidity fluctuation difference. The values ​​of d1 and Δd are not limited and can be determined as needed. For example, Δd can be, but is not limited to, 2%.

[0108] In some exemplary embodiments, the heating element 222 of the heating section 22 has a split structure, such as... Figure 16 As shown, the heating element 222 includes a first sub-heating element 2223 and a second sub-heating element 2224 that are independent of each other. The wiring part 21 includes a first sub-wiring part and a second sub-wiring part that are independent of each other. The first sub-wiring part is electrically connected to the first sub-heating element 2223, and the second sub-wiring part is electrically connected to the second sub-heating element 2224. The first sub-heating element 2223 is located below the second sub-heating element 2224, and the heating power of the first sub-heating element 2223 is greater than the heating power of the second sub-heating element 2224.

[0109] like Figure 19 As shown, heater 2 is controlled based on the current humidity, target humidity, and liquid level, including:

[0110] Based on the liquid level in the heating water tank 1 being within a set height range, the operation of the first sub-heater 2223 and the second sub-heater 2224 is controlled.

[0111] Based on the fact that the liquid level in the heating water tank 1 has not risen to the set height range and the water supply time has reached the first set time, the first sub-heater 2223 is controlled to operate and the second sub-heater 2224 is turned off. The first set time is longer than the time required for the liquid level in the heating water tank 1 to increase from zero to the set maximum liquid level.

[0112] Once the target humidity is reached in the target space, heater 2 is turned off.

[0113] In other words, when the liquid level in the heating water tank 1 is within the set height range, it indicates that there is enough water in the heating water tank 1. At this time, both the first sub-heater 2223 and the second sub-heater 2224 are running, and dry burning will not occur. In addition, the heating part 22 can be fully immersed in the water, which is beneficial to improving the humidification efficiency.

[0114] If the water level in the heating water tank 1 does not rise to the set height range within the first set time and the water supply time reaches the first set time, it indicates that the water volume in the heating water tank 1 is limited. At this time, only the first sub-heater 2223 is turned on to heat the water, while the second sub-heater 2224 is turned off to reduce the heat loss for air heating and save energy.

[0115] When the current humidity of the target space to be humidified reaches the target humidity, it indicates that the humidification requirement has been met, so heater 2 is turned off.

[0116] In this way, heater 2 has two working modes: it can operate at high power when the liquid level is high and at low power when the liquid level is low. This allows the heating power of heater 2 to match the liquid level in the water tank 1, taking into account both humidification needs and the concept of green energy saving.

[0117] The specific duration of the first set time interval is unrestricted. For example, the liquid level in the heating water tank 1 can be measured every first set interval (or the liquid level in the heating water tank 1 can be checked every first set interval to see if it is within the set height range, and the frequency of liquid level measurement can be higher). The first set time interval can be an integer multiple of the first set interval. Alternatively, the current humidity of the target humidified space can be measured every second set interval (or the current humidity of the target humidified space can be checked every second set interval to see if it has reached the target humidity, and the frequency of current humidity measurement can be higher). The first set time interval can be an integer multiple of the second set interval. The first set interval and the second set interval can be equal or unequal.

[0118] In some embodiments, such as Figure 19 As shown, heater 2 is controlled based on the current humidity, target humidity, and liquid level, and also includes:

[0119] After controlling the first sub-heater 2223 to operate and the second sub-heater 2224 to be turned off for a second set time, it is determined whether the liquid level in the heating water tank 1 has risen to the set height range.

[0120] Based on the rise of the liquid level in the heating water tank 1 to a set height range, return to the step of controlling the operation of the first sub-heater 2223 and the second sub-heater 2224;

[0121] Since the liquid level in the heating water tank 1 has not risen to the set height range, the process returns to the step of controlling the first sub-heater 2223 to run and the second sub-heater 2224 to shut down.

[0122] In other words, during the low-power operation of heater 2, the liquid level in the heating water tank 1 is also monitored. When the liquid level in the heating water tank 1 rises to the set height range, the second sub-heater 2224 is also activated, so that the total heating power of heater 2 matches the liquid level, thereby improving the humidification efficiency of the humidification device. When the liquid level in the heating water tank 1 does not rise to the set height range, the low-power heating state continues.

[0123] The specific duration of the second set interval is unrestricted. For example, the liquid level in the heating water tank 1 can be measured every first set interval (or every first set interval to determine if the liquid level in the heating water tank 1 is within the set height range, with a higher measurement frequency), and the second set interval can be an integer multiple of the first set interval. Alternatively, the current humidity of the target humidified space can be measured every second set interval (or every second set interval to determine if the current humidity of the target humidified space has reached the target humidity, with a higher measurement frequency), and the second set interval can be an integer multiple of the second set interval. The first and second set intervals can be equal or unequal.

[0124] In some exemplary embodiments, the humidification device further includes a water supply module configured to supply water to the heated water tank 1.

[0125] Control methods also include:

[0126] In response to the humidification command, the water supply module is activated to supply water to the heating water tank 1;

[0127] If the liquid level in the heating water tank 1 fails to rise to the set height range within the third set time period, an abnormal liquid level warning message will be issued.

[0128] Under normal circumstances, the water level in heating water tank 1 should rise to the set height within the third set time period. Otherwise, it may indicate a malfunction in the water supply module, abnormal water pressure, leakage in heating water tank 1, or other abnormal situation. Therefore, issuing a water level abnormality alert can remind the user to check in time to minimize potential losses. The third set time period can be equal to the first set time period.

[0129] The form in which the reminder message is sent is unrestricted; it can be an audio signal, a visual signal, a voice signal, or a video signal. Controlling the water supply module's startup includes opening the first inlet valve 32.

[0130] In some exemplary embodiments, the control method further includes:

[0131] The water supply module is shut down when the liquid level in the heating water tank 1 rises to the upper limit of the set height range.

[0132] The water supply module is activated when the liquid level in the heating water tank 1 drops to the lower limit of the set height range.

[0133] In other words, during the operation of the humidification device, the water supply module can be automatically opened and closed according to the liquid level in the heating water tank 1, so that the liquid level in the heating water tank 1 can be maintained within the set height range.

[0134] In other embodiments, the first water inlet valve 32 can also be configured as a flow switch, which can dynamically adjust the opening of the flow switch by the change in the amount of water in the humidification water tank, so that the liquid level in the heating water tank 1 can be maintained within a set height range.

[0135] In some exemplary embodiments, the control method further includes: in response to a humidification command, controlling the steam pipeline 5 to be turned on, so that the steam pipeline 5 outputs steam to the target space to be humidified.

[0136] In some exemplary embodiments, the control method further includes controlling the heating water tank 1 to drain water based on the shutdown of the heater 2. This prevents water from accumulating in the heating water tank 1 for an extended period, which could lead to bacterial growth.
