[0038] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0039] The following describes a water receiving tray assembly 1 according to an embodiment of the present invention with reference to the accompanying drawings. The water receiving tray assembly 1 can be used in an air treatment device 100 .

[0040] like Figure 1-Figure 2 As shown, a water receiving tray assembly 1 for an air handling device 100 according to an embodiment of the present invention comprises: a water receiving tray 11 , a siphon assembly 12 and a water leakage detection device 13 .

[0041] Among them, a water receiving space 11a can be defined in the water receiving pan 11, and a drain port 11b connected to the water receiving space 11a can be provided on the water receiving pan 11. For example, the water receiving pan assembly 1 can be arranged in an air conditioner, and the heat exchanger of the air conditioner can be arranged above the water receiving pan 11. Condensed water can form on the surface of the heat exchanger during heat exchange, and the condensed water can drip into the water receiving space 11a under the action of gravity, and the condensed water in the water receiving pan 11 can be discharged from the drain port 11b. For another example, the water receiving pan assembly 1 can be arranged in a humidifying device, and the water tank of the humidifying device can be arranged above the water receiving pan 11. The water overflowing from the water tank can drip into the water receiving space 11a under the action of gravity, and the water in the water receiving pan 11 can be discharged from the drain port 11b.

[0042] like Figure 5 and Figure 7As shown, the siphon assembly 12 may include a siphon 121 and a sleeve 122. The siphon 121 may include a first pipe portion 121a and a second pipe portion 121b that are connected to each other. The second pipe portion 121b may be connected to the drain outlet 11b, and the water inlet end of the first pipe portion 121a may be located above the water outlet end of the second pipe portion 121b. One axial end of the sleeve 122 may be open. The sleeve 122 may be sleeved on the first pipe portion 121a and be gap-matched with the first pipe portion 121a to define a water inlet flow path 12a. The water inlet flow path 12a is respectively connected to the water receiving space 11a and the water inlet end of the first pipe portion 121a, and the water inlet end of the water inlet flow path 12a may be located above the water outlet end of the second pipe portion 121b.

[0043] Specifically, the siphon assembly 12 can introduce the water in the water receiving space 11a into the drain port 11b to achieve the purpose of drainage. Among them, the water receiving space 11a, the water inlet flow path 12a, the first pipe part 121a and the second pipe part 121b are interconnected. When the liquid level in the water receiving space 11a does not reach the set height, the water receiving tray 11 is in a water storage state. According to the principle of communicating vessels, the liquid level height in the water receiving space 11a changes synchronously with the liquid level height in the water inlet flow path 12a. When the liquid level height in the water receiving space 11a is higher than the height of the water inlet end of the first pipe part 121a, the water in the water inlet flow path 12a begins to enter the first pipe part 121a, and the water can be discharged through the first pipe part 121a, the second pipe part 121b and the drain port 11b in sequence. According to the siphon principle, the water entering the siphon 121 can discharge the air in the siphon 121, thereby forming a negative pressure in the siphon 121. Thus, the water in the water receiving space 11a can be discharged through the water inlet flow path 12a, the siphon 121 and the drain port 11b in sequence. When the liquid level in the water receiving space 11a is lower than the height of the water inlet end of the water inlet flow path 12a, the siphon assembly 12 stops draining.

[0044] For example, the sleeve 122 and the first tube portion 121a can both be formed into a cylindrical shape, and the inner diameter of the sleeve 122 is larger than the outer diameter of the first tube portion 121a. The sleeve 122 includes an open end 122b and a sealed end 122a. The sleeve 122 can be sleeved on the first tube portion 121a through the open end 122b, and the sealed end 122a is located above the first tube portion 121a and is spaced from the water inlet end of the first tube portion 121a. Therefore, when the water entering the first tube portion 121a discharges the air in the siphon 121, a stable negative pressure can be formed in the siphon 121, which can improve the drainage effect of the siphon assembly 12.

[0045] like Figure 1-Figure 2As shown, the water leakage detection device 13 can be arranged on the water receiving tray 11, and the trigger switch of the water leakage detection device 13 can be located below the water inlet end of the first tube portion 121a. The water leakage detection device 13 can be configured to detect the change of the liquid level in the water receiving space 11a when the trigger switch is triggered and the first tube portion 121a is not filled with water to determine whether the water receiving tray 11 is leaking.

[0046] Specifically, when water begins to flow into the water receiving space 11a, since the water inlet end of the first tube portion 121a is located above the water outlet end of the second tube portion 121b, the water receiving tray 11 can first store water, and the liquid level in the water receiving space 11a changes synchronously with the liquid level in the water inlet flow path 12a. During the process of water storage in the water receiving tray 11, the trigger switch of the water leakage detection device 13 can be triggered, and at this time, the water leakage detection device 13 can detect the change of the liquid level in the water receiving space 11a, thereby determining whether the water receiving tray 11 is leaking. For example, when the water leakage detection device 13 detects that the liquid level in the water receiving space 11a drops when the water receiving tray 11 is storing water, it can be indicated that the water receiving tray 11 is leaking, and the water leakage detection device 13 can send a warning signal to remind the user to inspect the water receiving tray 11. When the liquid level in the water receiving space 11a is higher than the height of the water inlet end of the first pipe portion 121a, the water in the water inlet flow path 12a begins to enter the siphon 121, and the siphon assembly 12 begins to drain water, and the water leakage detection device 13 stops working.

[0047] In a specific example of the present invention, the water leakage detection device 13 may include: a control mainboard, a trigger switch, a first liquid level detection sensor, a second liquid level detection sensor and an alarm device, wherein the trigger switch, the first liquid level detection sensor, the second liquid level detection sensor and the alarm device are respectively connected to the control mainboard for communication. The trigger switch is arranged below the water inlet end of the first tube portion 121a, and the second liquid level detection sensor is arranged flush with the water inlet end of the first tube portion 121a to detect whether the liquid level reaches the water inlet end of the first tube portion 121a. When the liquid level height in the water receiving space 11a is flush with the height of the trigger switch, the trigger switch is triggered, the first liquid level detection sensor starts to work, the first liquid level detection sensor starts to detect the real-time liquid level in the water receiving space 11a and sends the detection data to the control mainboard, and the control mainboard can judge the liquid level changes in the water receiving space 11a at two adjacent moments. If the second liquid level detection sensor does not detect that the liquid level has reached the water inlet end of the first pipe portion 121a and the control mainboard detects that the liquid level in the water receiving space 11a has dropped, the control mainboard controls the alarm device to send an alarm signal to prompt the user to inspect the water tray 11. If the second liquid level detection sensor detects that the liquid level has reached the water inlet end of the first pipe portion 121a, the water leakage detection device 13 stops working and the siphon assembly 12 starts to drain water.

[0048] It should be noted that the water leakage detection device 13 may also only include the first liquid level detection sensor. When the liquid level in the water receiving space 11a is flush with the height of the trigger switch, the trigger switch is triggered and the first liquid level detection sensor starts to work. The control mainboard can determine whether the water receiving tray 11 is leaking based on the change in the liquid level in the water receiving space 11a at two adjacent moments detected by the first liquid level detection sensor. When the liquid level in the water receiving space 11a reaches the water inlet end of the first pipe portion 121a, the siphon assembly 12 starts to drain water.

[0049] According to the water receiving tray assembly 1 for the air handling device 100 according to the embodiment of the present invention, by providing the siphon tube assembly 12 and the water leakage detection device 13, the siphon tube assembly 12 can play the dual role of storing water and draining water from the water receiving tray 11, and the water leakage detection device 13 can detect whether the water receiving tray 11 is leaking, thereby detecting the leakage of the water receiving tray 11 while satisfying the normal drainage of the water receiving tray 11, thereby solving the problem of water leakage of the water receiving tray 11 in time, and having strong practical performance.

[0050] like Figure 3-Figure 4 As shown, according to some embodiments of the present invention, the water receiving tray assembly 1 may further include a water baffle 14, which may be disposed in the water receiving tray 11 and cooperate with the water receiving tray 11 to define a water receiving space 11a, and the height of the first pipe portion 121a may be lower than the height of the water baffle 14, and the second pipe portion 121b may pass through the water baffle 14 to be connected to the drain outlet 11b, thereby facilitating water storage in the water receiving tray 11.

[0051] Specifically, the siphon 121 can be sealed with the water baffle 14 and the second pipe portion 121b passes through the water baffle 14 and communicates with the drain port 11b, so that the water baffle 14 can prevent the water in the water receiving space 11a from being directly discharged through the drain port 11b, and can store water in the water receiving tray 11. Moreover, the height of the water baffle 14 is higher than the height of the water inlet end of the first pipe portion 121a, thereby ensuring that the water in the water receiving tray 11 can be smoothly discharged through the siphon assembly 12.

[0052] Optionally, the water baffle 14 may be sealed with the inner peripheral wall of the water receiving tray 11, or the water baffle 14 may be formed as an integral part with the water receiving tray 11. Figure 1In the specific example shown, the water receiving tray 11 may include a bottom plate 111 and a surrounding plate 112, wherein the surrounding plate 112 extends in the circumferential direction of the bottom plate 111 and forms a closed ring, and the surrounding plate 112 extends upward relative to the bottom plate 111. The water baffle 14 is arranged in the water receiving tray 11, and the water baffle 14 and the bottom plate 111 form an integrally formed part, and the two ends of the water baffle 14 in the length direction are respectively sealed with the surrounding plate 112, and the siphon assembly 12 is arranged on the water baffle 14, thereby the bottom plate 111, the surrounding plate 112 and the water baffle 14 can form a closed water receiving space 11a. Of course, the water baffle 14 can also be formed as an integral injection molded part with the surrounding plate 112, and the water baffle 14 can also be formed as an integral injection molded part with the surrounding plate 112 and the bottom plate 111 at the same time.

[0053] In some embodiments of the present invention, the siphon tube 121 can be formed as an integral part with the water baffle 14, thereby making the matching structure of the water baffle 14 and the siphon tube 121 tighter, and improving the water storage effect of the water baffle 14. For example, the siphon tube 121 can be formed as an integral injection molded part with the water baffle 14. Of course, it is understandable that the siphon tube 121 can also be formed as a split part with the water baffle 14, wherein the first tube portion 121a can be located in the water receiving space 11a, one end of the second tube portion 121b is located in the water receiving space 11a to be connected to the first tube portion 121a, and the other end of the second tube portion 121b can pass through the water baffle 14 to communicate with the drain port 11b, and the second tube portion 121b is sealed and matched with the water baffle 14.

[0054] like Figure 3-Figure 4 As shown, in some embodiments of the present invention, the sleeve 122 may be provided with a connecting portion 1221 extending toward the water baffle 14, and the connecting portion 1221 may be fixed to the water baffle 14, thereby facilitating the fixation of the siphon tube assembly 12 and making the overall structure of the water receiving tray assembly 1 more compact.

[0055] For example, the connection part 1221 can be arranged at the top of the sleeve 122, one end of the connection part 1221 is connected to the sleeve 122, the other end of the connection part 1221 extends toward the direction close to the water baffle 14, and the connection part 1221 is provided with a mounting hole 1221a. The water baffle 14 is provided with a screw column 141, and the mounting hole 1221a is arranged opposite to the threaded hole on the screw column 141. A fixing screw can be passed through the mounting hole 1221a and threadedly connected to the threaded column, thereby fixing the sleeve 122 to the water baffle 14. Of course, it is understandable that the connection part 1221 can also be connected to the water baffle 14 by riveting, and the connection part 1221 can also be fixed to the water baffle 14 by adhesive bonding.

[0056] It should be noted that the fixing method of the sleeve 122 is not limited to this. For example, the sleeve 122 can also be fixed to the enclosure 112 of the water receiving tray 11, and the sleeve 122 can also be fixed to the siphon 121, as long as the water inlet flow path 12a can be defined between the sleeve 122 and the first pipe portion 121a.

[0057] like Figure 6-Figure 7 As shown, according to some embodiments of the present invention, a water collecting portion 1111 that is recessed downward may be provided on the bottom wall of the water receiving tray 11, and the water inlet end of the water inlet flow path 12a may be located in the water collecting portion 1111, thereby improving the drainage effect of the siphon assembly 12. It can be understood that since the water collecting portion 1111 is recessed downward relative to the bottom wall of the water receiving tray 11, according to the principle of "water flows to lower places", the water entering the water receiving space 11a may first enter the water collecting portion 1111. Therefore, the water in the water receiving tray 11 can be drained cleanly by the water inlet end of the water inlet flow path 12a being located in the water collecting portion 1111.

[0058] like Figure 4 As shown, in some embodiments of the present invention, a guide slope 1112 may be provided on the bottom wall of the water receiving tray 11 to guide the water in the water receiving space 11a to the water collecting portion 1111, thereby improving the drainage efficiency of the water receiving tray assembly 1. Optionally, a plurality of guide slopes 1112 connected in sequence may be provided on the bottom wall of the water receiving tray 11, and in the direction from top to bottom, each guide slope 1112 may extend obliquely toward the direction close to the water collecting portion 1111, thereby guiding the water entering the water receiving space 11a to flow to the water collecting portion 1111, and ensuring that the siphon assembly 12 drains the water in the water receiving space 11a.

[0059] like Figure 8 As shown, according to some embodiments of the present invention, the water leakage detection device 13 may include a float 131, and the float 131 may rise with the liquid level in the water receiving tray 11 to trigger the trigger switch, thereby making the triggering method of the trigger switch simpler and improving the detection accuracy of the water leakage detection device 13.

[0060] In some embodiments of the present invention, both the float 131 and the trigger switch can be formed as magnetic parts, and the float 131 can cooperate with the trigger switch by magnetic attraction to trigger the trigger switch, thereby making the cooperation mode between the float 131 and the trigger switch more ingenious, and improving the detection accuracy of the water leakage detection device 13. Optionally, the water leakage detection device 13 may also include a guide cylinder (not shown), which is arranged adjacent to the trigger switch and is connected to the water receiving space 11a, thereby making the guide cylinder consistent with the liquid level in the water receiving space 11a. The guide cylinder extends in the vertical direction, and the float 131 is arranged in the guide cylinder. Thus, through the above arrangement, the guide cylinder can limit the float 131, and can prevent the float 131 from floating to a position away from the trigger switch so that the trigger switch cannot be triggered normally, thereby improving the detection accuracy of the water leakage detection device 13.

[0061] The working principle of the water leakage detection device 13 according to the present invention is described in detail below with reference to a specific embodiment.

[0062] The water leakage detection device 13 may include: a control mainboard, a float 131, a trigger switch, a first liquid level detection sensor, a second liquid level detection sensor and an alarm device, wherein the trigger switch, the first liquid level detection sensor, the second liquid level detection sensor and the alarm device are respectively connected to the control mainboard for communication. The trigger switch is arranged below the water inlet end of the first pipe part 121a, and the trigger switch is a magnetic material piece. The guide cylinder is arranged adjacent to the trigger switch and the guide cylinder is connected to the water receiving space 11a, thereby making the guide cylinder consistent with the liquid level in the water receiving space 11a. The guide cylinder extends in the vertical direction, the float 131 is formed as a spherical magnetic material piece and the float 131 is arranged in the guide cylinder. The second liquid level detection sensor is arranged flush with the water inlet end of the first pipe part 121a to detect whether the liquid level reaches the water inlet end of the first pipe part 121a.

[0063] When water starts to flow into the water receiving tray 11, the float 131 can float on the water surface. When the liquid level in the water receiving space 11a rises to a certain height, the float 131 cooperates with the trigger switch magnetically, the trigger switch is triggered, and the first liquid level detection sensor starts to work. The first liquid level detection sensor starts to detect the real-time liquid level in the water receiving space 11a and sends the detection data to the control main board, and the control main board can judge the liquid level changes in the water receiving space 11a at two adjacent moments. If the second liquid level detection sensor does not detect that the liquid level has reached the water inlet end of the first tube part 121a and the control main board detects that the liquid level in the water receiving space 11a has dropped, the control main board controls the alarm device to send an alarm signal to prompt the user to inspect the water receiving tray 11. If the second liquid level detection sensor detects that the liquid level has reached the water inlet end of the first tube part 121a, the water leakage detection device 13 stops working and the siphon assembly 12 starts to drain water.

[0064] like Figure 4 As shown, according to some embodiments of the present invention, a water guide groove 1113 may be provided on the bottom wall of the water receiving tray 11, and in the direction from top to bottom, the water guide groove 1113 may be inclined and extended toward the direction close to the water leakage detection device 13 to guide the water to the water leakage detection device 13, thereby, the water entering the water receiving space 11a may first flow along the water guide groove 1113 to the water leakage detection device 13, thereby improving the detection sensitivity of the water leakage detection device 13.

[0065] like Figure 7 As shown, according to some embodiments of the present invention, the first tube portion 121a can extend vertically and the second tube portion 121b can extend horizontally, so that the first tube portion 121a and the second tube portion 121b can be roughly formed into an L shape, thereby making the overall structure of the siphon tube 121 more compact and achieving a good drainage effect.

[0066] The following describes in detail a water tray assembly 1 according to a specific embodiment with reference to the accompanying drawings. The water tray assembly 1 may be provided in an air handling device 100. It should be understood that the following description is merely exemplary and does not specifically limit the present invention.

[0067] like Figure 1-Figure 2 As shown, the water receiving tray assembly 1 according to the embodiment of the present invention includes: a water receiving tray 11 , a siphon assembly 12 , a water leakage detection device 13 and a water baffle 14 .

[0068] The water receiving pan 11 may include a bottom plate 111 and a surrounding plate 112, wherein the surrounding plate 112 extends in the circumferential direction of the bottom plate 111 and forms a closed ring, and the surrounding plate 112 extends upward relative to the bottom plate 111. A water baffle 14 is disposed in the water receiving pan 11, and the water baffle 14 and the bottom plate 111 form an integrally formed part, and both ends of the water baffle 14 in the length direction are respectively sealed with the surrounding plate 112, thereby the bottom plate 111, the surrounding plate 112 and the water baffle 14 can form a closed water receiving space 11a, and the water receiving pan 11 may be provided with a drain port 11b connected to the water receiving space 11a.

[0069] like Figure 3 and Figure 7As shown, the siphon assembly 12 may include a siphon 121 and a sleeve 122. The siphon 121 may include a first pipe portion 121a and a second pipe portion 121b that are connected. The first pipe portion 121a extends in a vertical direction, and the second pipe portion 121b extends in a horizontal direction. The second pipe portion 121b may be connected to the drain outlet 11b. The water inlet end of the first pipe portion 121a may be located above the water outlet end of the second pipe portion 121b. One axial end of the sleeve 122 may be open. The sleeve 122 may be sleeved on the first pipe portion 121a and be gap-matched with the first pipe portion 121a to define a water inlet flow path 12a. The water inlet flow path 12a is connected to the water receiving space 11a and the water inlet end of the first pipe portion 121a, respectively. The water inlet end of the water inlet flow path 12a may be located above the water outlet end of the second pipe portion 121b. As shown Figure 6-Figure 7 As shown, a downwardly recessed water collecting portion 1111 may be provided on the bottom wall of the water receiving tray 11 , and the water inlet end of the water inlet flow path 12 a may be located in the water collecting portion 1111 .

[0070] like Figure 3 As shown, the sleeve 122 and the first pipe part 121a can both be formed into a cylindrical shape, and the inner diameter of the sleeve 122 is greater than the outer diameter of the first pipe part 121a. The sleeve 122 includes an open end 122b and a sealed end 122a. The sleeve 122 can be sleeved on the first pipe part 121a through the open end 122b, and the sealed end 122a is located above the first pipe part 121a and is spaced from the water inlet end of the first pipe part 121a. Therefore, when the water entering the first pipe part 121a discharges the air in the siphon 121, a stable negative pressure can be formed in the siphon 121, which can improve the drainage effect of the siphon assembly 12. A connecting portion 1221 is provided at the top of the sleeve 122, one end of the connecting portion 1221 is connected to the sleeve 122, and the other end of the connecting portion 1221 extends toward the direction close to the water retaining plate 14, and a mounting hole 1221a is provided on the connecting portion 1221. The water baffle 14 is provided with a screw column 141, and the mounting hole 1221a is arranged opposite to the threaded hole on the screw column 141. A fixing screw can be passed through the mounting hole 1221a and threadedly connected with the threaded column, thereby fixing the sleeve 122 on the water baffle 14.

[0071] The water leakage detection device 13 may include: a control mainboard, a float 131, a trigger switch, a first liquid level detection sensor, a second liquid level detection sensor and an alarm device, wherein the trigger switch, the first liquid level detection sensor, the second liquid level detection sensor and the alarm device are respectively connected to the control mainboard for communication. The trigger switch is arranged below the water inlet end of the first pipe part 121a, and the trigger switch is a magnetic material piece. The guide cylinder is arranged adjacent to the trigger switch and the guide cylinder is connected to the water receiving space 11a, thereby making the guide cylinder consistent with the liquid level in the water receiving space 11a. The guide cylinder extends in the vertical direction, the float 131 is formed as a spherical magnetic material piece and the float 131 is arranged in the guide cylinder. The second liquid level detection sensor is arranged flush with the water inlet end of the first pipe part 121a to detect whether the liquid level reaches the water inlet end of the first pipe part 121a.

[0072] Specifically, when water starts to flow into the water receiving tray 11, the float 131 can float on the water surface. When the liquid level in the water receiving space 11a rises to a certain height, the float 131 cooperates with the trigger switch magnetically, the trigger switch is triggered, and the first liquid level detection sensor starts to work. The first liquid level detection sensor starts to detect the real-time liquid level in the water receiving space 11a and sends the detection data to the control main board, and the control main board can judge the liquid level changes in the water receiving space 11a at two adjacent moments. If the second liquid level detection sensor does not detect that the liquid level has reached the water inlet end of the first tube part 121a and the control main board detects that the liquid level in the water receiving space 11a has dropped, the control main board controls the alarm device to send an alarm signal to prompt the user to inspect the water receiving tray 11. If the second liquid level detection sensor detects that the liquid level has reached the water inlet end of the first tube part 121a, the water leakage detection device 13 stops working and the siphon assembly 12 starts to drain water.

[0073] It can be understood that since the water receiving space 11a, the water inlet flow path 12a, the first pipe part 121a and the second pipe part 121b are interconnected. When the liquid level in the water receiving space 11a does not reach the set height, the water receiving pan 11 is in a water storage state. According to the communicating vessel principle, the liquid level in the water receiving space 11a changes synchronously with the liquid level in the water inlet flow path 12a. When the liquid level in the water receiving pan 11 is higher than the height of the water inlet end of the first pipe part 121a, the water in the water inlet flow path 12a begins to enter the siphon 121. According to the siphon principle, the water entering the siphon 121 can discharge the air in the siphon 121, thereby forming a negative pressure in the siphon 121. As a result, the water in the water receiving space 11a can be discharged through the water inlet flow path 12a, the siphon 121 and the drain port 11b. When the liquid level in the water receiving space 11a is lower than the height of the water inlet end of the water inlet flow path 12a, the siphon assembly 12 stops draining. Since the water inlet end of the water inlet flow path 12 a is located in the water collecting portion 1111 , the siphon assembly 12 can drain the water in the water receiving tray 11 .

[0074] The air treatment device 100 according to the embodiment of the present invention includes the water receiving tray assembly 1 for the air treatment device 100 according to the above embodiment of the present invention.

The siphon tube assembly 12 can play a dual role of storing water and draining water from the water receiving tray 11. The water leakage detection device 13 can detect whether the water receiving tray 11 is leaking, thereby detecting the leakage of the water receiving tray 11 while satisfying the normal drainage of the water receiving tray 11, thereby solving the problem of water leakage of the water receiving tray 11 in time, and greatly improving the product practical performance of the air treatment equipment 100.

Among them, the water supply tank 3 is connected to the water source through the water inlet valve 31, and the heating water tank 2 is connected to the water supply tank 3 through the water supply pipe 4. The height of the water outlet on the water supply tank 3 is higher than the height of the water inlet on the heating water tank 2. Therefore, according to the siphon principle, the water in the water supply tank 3 can enter the heating water tank 2 through the water supply pipe 4.

[0077] The heating water tank 2 is provided with a PTC heating tube, which can heat the water in the heating water tank 2 to form water vapor. The heating water tank 2 is provided with a water vapor outlet 21, and the water vapor in the heating water tank 2 can be discharged through the water vapor outlet 21. The water vapor discharged from the water vapor outlet 21 can be introduced into a specific space (such as an indoor space) through a connecting pipeline, or the water vapor can be directly discharged into a specific space through the water vapor outlet 21.

[0078] When water leakage occurs in the water replenishment tank 3 and / or the heating water tank 2, the water leaked from the water replenishment tank 3 and / or the heating water tank 2 may drip into the water receiving tray 11, and the siphon assembly 12 may have the functions of storing and draining water, and may not only discharge the water in the water receiving tray 11, but may also cooperate with the water leakage detection device 13 to detect whether the water receiving tray 11 is leaking.

[0079] Optionally, the humidifying device may include a plurality of heating water tanks 2, and the water replenishing tank 3 is connected to each heating water tank 2 through a plurality of water supply pipes 4.

In this way, the humidification efficiency of the humidifying device can be improved, and the user's flexibility of use can also be improved. Of course, the humidifying device can also include a heating water tank 2, and the heating water tank 2 is provided with a plurality of water vapor outlets 21, and the plurality of water vapor outlets 21 can discharge water vapor to the outside at the same time.
