[0041] The embodiments of the present invention are described in detail below, and examples of the embodiments 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.

[0042] At present, in order to realize the humidification function, the humidifying device is usually equipped with a water tank. In the related art, the water tank is mostly fixed in the shell of the humidifying device, and the equipped water tank is mostly a closed water tank. When it is necessary to add water to the water tank, the shell must be disassembled first to take out the water tank, resulting in a poor user experience. In addition, the closed water tank needs to be welded and sealed, which is costly and inconvenient to clean.

[0043] Based on this, refer to Figure 1 and Figure 2As shown in the figure, the humidifying device 1000 of the embodiment of the present utility model includes a first housing 100, a first water tank 200, a second water tank 300, and a valve assembly 400. Among them, the first housing 100 can be understood as the main body housing of the humidifying device 1000. The first water tank 200 and the second water tank 300 are mainly used for temporarily storing water. The humidifying device 1000 further includes a humidifying module 500. The first water tank 200 and the second water tank 300 are mainly used for supplying water to the humidifying module 500. The humidifying module 500 has a humidifying function and can increase the humidity of the air. Specifically, the first water tank 200 directly supplies water to the humidifying module 500, and the second water tank 300 directly supplies water to the first water tank 200. The valve assembly 400 is used to conduct or block the first water tank 200 and the second water tank 300.

[0044] Specifically, referring to Figure 2 As shown in the figure, the first housing 100 is provided with an installation position 110, which can be understood as a groove, hole or cavity. The first water tank 200 is fixedly installed in the installation position 110, and the second water tank 300 is detachably installed in the installation position 110. The second water tank 300 can be inserted into the installation position 110 or directly taken out from the installation position 110, so that the second water tank 300 is separated from the installation position 110. Referring to Figure 2 and Figure 3 As shown in the figure, the first water tank 200 and the second water tank 300 are arranged opposite to each other in the horizontal direction. The valve assembly 400 includes a first switching valve 410 and a second switching valve 420. The first switching valve 410 is connected to the side of the first water tank 200 facing the second water tank 300. The first switching valve 410 is used to conduct or cut off the inner cavity of the first water tank 200 and the outside of the first water tank 200. Referring to Figure 5 and Figure 8 As shown in the figure, in some embodiments, the upper end of the first water tank 200 is open. The first water tank 200 can be understood as a water tank structure. The first switching valve 410 is connected to the side of the first water tank 200. It can be understood that the first switching valve 410 is connected to one side of the first water tank 200 in the horizontal direction, and the first switching valve 410 faces the second water tank 300. The second switching valve 420 is connected to the side of the second water tank 300 facing the first water tank 200. It can be understood that the second switching valve 420 is connected to one side of the second water tank 300 in the horizontal direction, and the second switching valve 420 faces the first water tank 200. The second switching valve 420 is used to conduct or cut off the inner cavity of the second water tank 300 and the outside of the second water tank 300.

[0045] It should be noted that the first water tank 200 can be understood as a fixed water tank. Generally speaking, the first water tank 200 remains fixed in the installation position 110, and the second water tank 300 can be understood as a movable water tank, and the second water tank 300 can be taken out from the installation position 110.

[0046] The valve assembly 400 has a connected state and a separated state. Refer to Figure 2 As shown, the second water tank 300 is installed in the installation position 110. At this time, the valve assembly 400 is in the connected state, the first switching valve 410 is connected to the second switching valve 420, and the first switching valve 410 and the second switching valve 420 are in the open state, thereby conducting the inner cavity of the first water tank 200 and the inner cavity of the second water tank 300. The water in the second water tank 300 can flow into the first water tank 200 through the first switching valve 410 and the second switching valve 420, allowing the second water tank 300 to supply water to the first water tank 200. When it is necessary to replenish water or clean the second water tank 300, or, it can be along Figure 1 and Figure 2 the disassembly direction shown in, directly take out the second water tank 300 from the installation position 110 from back to front. After taking out the second water tank 300 from the installation position 110, the valve assembly 400 is in the separated state, the first switching valve 410 is separated from the second switching valve 420, and moreover, the first switching valve 410 and the second switching valve 420 are in the closed state, thereby blocking the inner cavity of the first water tank 200 and the inner cavity of the second water tank 300, and moreover, the water in the first water tank 200 will not flow out from the first switching valve 410, and the water in the second water tank 300 will not flow out from the second switching valve 420, avoiding water leakage during the process of taking out the second water tank 300. When the replenishment of the second water tank 300 is completed, the second water tank 300 can be directly inserted into the installation position 110 from front to back.

[0047] It should be explained that when it is necessary to replenish water to the second water tank 300, it can be that the water in the second water tank 300 is exhausted, or it can be that the liquid level in the second water tank 300 drops to a certain liquid level height, and the water in the second water tank 300 is too little, there is a need for water replenishment.

[0048] It should be noted that the first water tank 200 and the second water tank 300 of this embodiment are hermetically connected through the valve assembly 400. Compared with the traditional closed water tank that needs to be hermetically sealed by welding, the manufacturing cost of this embodiment is lower.

[0049] Refer to Figure 2 As shown, in some embodiments, the humidifying device 1000 includes a water pump 600. The water pump 600 is arranged in the first water tank 200. The water pump 600 transports the water in the first water tank 200 to the humidifying module 500 through a connecting pipe 610. The humidifying module 500 is provided with a return port 510. The return port 510 is communicated with the inner cavity of the first water tank 200. The return port 510 is used to return the water of the humidifying module 500 to the first water tank 200 for recycling. When the valve assembly 400 is in the connected state, the first water tank 200 is communicated with the second water tank 300, and the water pump 600 can pump the water in the second water tank 300 into the first water tank 200.

[0050] In some embodiments, the humidification module 500 includes a fan and a wet film. The water pump 600 pumps the water in the first water tank 200 to the wet film through the connecting pipe 610, so that the wet film is wetted with water. The fan drives the air flow through the wet film, thereby increasing the humidity in the air flow and realizing the humidification function. The first water tank 200 and the second water tank 300 are located below the humidification module 500. Therefore, it is necessary for the water pump 600 to transport the water upward to the humidification module 500. The water in the wet film can flow directly into the first water tank 200 from the return port 510 under the action of gravity, realizing the water flow circulation.

[0051] It should be noted that in the above embodiments, the first water tank 200 is fixedly installed in the installation position 110, which means that the first water tank 200 and the first housing 100 can be fixedly connected to the first housing 100 through fasteners, snap structures or locking structures. It can also be understood that the first water tank 200 and the first housing 100 are detachably connected, so that the first water tank 200 can be removed from the installation position 110, thereby facilitating the cleaning of the inner cavity of the first water tank 200 and improving the user experience.

[0052] Refer to Figure 8 and Figure 9 As shown, in some embodiments, the first switching valve 410 includes a first insertion tube 414 and a first valve core. The first insertion tube 414 can be understood as passing through the first water tank 200. Part of the structure of the first insertion tube 414 is located inside the first water tank 200, and part of the structure of the first insertion tube 414 is located outside the first water tank 200. The first insertion tube 414 is a tubular structure, and the first insertion tube 414 is communicated with the inner cavity of the first water tank 200. The first insertion tube 414 can conduct the inner cavity of the first water tank 200 and the outside of the first water tank 200. The first valve core passes through the first insertion tube 414. The first valve core can open or close the first insertion tube 414. By the first valve core, the conduction or blockage between the inner cavity of the first water tank 200 and the outside of the first water tank 200 can be controlled.

[0053] Refer to Figure 6 and Figure 7 As shown, the second switching valve 420 includes a second insertion tube 424 and a second valve core. The second insertion tube 424 can be understood as passing through the second water tank 300. Part of the structure of the second insertion tube 424 is located inside the second water tank 300, and part of the structure of the second insertion tube 424 is located outside the second water tank 300. The second insertion tube 424 is a tubular structure, and the second insertion tube 424 is communicated with the inner cavity of the second water tank 300. The second insertion tube 424 can conduct the inner cavity of the second water tank 300 and the outside of the second water tank 300. The second valve core passes through the second insertion tube 424. The second valve core can open or close the second insertion tube 424. By the second valve core, the conduction or blockage between the inner cavity of the second water tank 300 and the outside of the second water tank 300 can be controlled.

[0054] Refer to Figure 9As shown, a sealing sleeve 415 is sleeved on the outer periphery of the first insertion tube 414. Along the axial direction of the first insertion tube 414, the length of the sealing sleeve 415 is greater than that of the first insertion tube 414. Refer to Figure 3 As shown, when the valve assembly 400 is in a connected state, the second insertion tube 424 is inserted into the sealing sleeve 415. The sealing sleeve 415 is mainly used to seal the first insertion tube 414 and the second insertion tube 424, which can play a sealing role to avoid water leakage. The sealing sleeve 415 is fixedly connected to the first insertion tube 414 to ensure that when the second insertion tube 424 is separated from the sealing sleeve 415, it will not be pulled out of the sealing sleeve 415 together.

[0055] It should be noted that the axis of the first insertion tube 414 is parallel to the axis of the second insertion tube 424, and the axis of the first insertion tube 414 is parallel to the insertion direction of the second water tank 300 inserted into the installation position 110, and the axis of the second insertion tube 424 is parallel to the insertion direction of the second water tank 300 inserted into the installation position 110. During the process of inserting the second water tank 300 into the installation position 110, it is ensured that the second insertion tube 424 can be directly inserted into the sealing sleeve 415. Specifically, refer to Figure 3 As shown, the axes of the first insertion tube 414 and the second insertion tube 424 can be arranged in the front-back direction.

[0056] Refer to Figure 3 and Figure 9 As shown, in some embodiments, an inverted buckle structure 4151 is provided on the inner wall of the sealing sleeve 415. The second insertion tube 424 is clamped with the inverted buckle structure 4151, which can improve the fixing effect and ensure the stable connection between the second insertion tube 424 and the sealing sleeve 415. The inverted buckle structure 4151 can be understood as a cantilever structure. The inverted buckle structure 4151 abuts against the outer peripheral wall of the second insertion tube 424, thereby clamping the second insertion tube 424. In some embodiments, the sealing sleeve 415 can be made of materials such as rubber or silica gel.

[0057] Refer to Figure 2 As shown, in some embodiments, the installation position 110 is located at the bottom of the first housing 100, that is, the second water tank 300 is installed at the bottom of the first housing 100, and the first water tank 200 is also installed at the bottom of the first housing 100. Moreover, the first water tank 200 and the second water tank 300 are located at the same horizontal position. The volume of the second water tank 300 is larger than that of the first water tank 200. The second water tank 300 can store more water. The first water tank 200 mainly plays a role of transfer, which can reasonably utilize the installation space of the first housing 100 and reduce the occupied space of the whole machine.

[0058] Refer to Figure 9As shown, in some embodiments, the first valve element includes a first valve stem 411 and a first sealing plug 412. The first valve stem 411 is inserted into the first insertion tube 414. The first valve stem 411 extends along the axis of the first insertion tube 414, and the first valve stem 411 can move along the axial direction of the first insertion tube 414. The first sealing plug 412 is connected to the first valve stem 411, and the first valve stem 411 can drive the first sealing plug 412 to move along the axis of the first valve stem 411. The first sealing plug 412 can close or open the first insertion tube 414. Specifically, the first sealing plug 412 is located in the inner cavity of the first water tank 200. When the first sealing plug 412 abuts against the end of the first insertion tube 414, the first sealing plug 412 seals the first insertion tube 414, causing the first switching valve 410 to be in the closed state. When the first sealing plug 412 disengages from the first insertion tube 414, that is, the first sealing plug 412 does not contact the first insertion tube 414, at this time, the first switching valve 410 is in the open state, the first insertion tube 414 communicates with the inner cavity of the first water tank 200, and the water in the first water tank 200 can flow into the first insertion tube 414 and thus flow out of the first water tank 200.

[0059] Referring to Figure 7 As shown, in some embodiments, the second switching valve 420 includes a second valve stem 421 and a second sealing plug 422. The second valve stem 421 is inserted into the second insertion tube 424. The second valve stem 421 extends along the axis of the second insertion tube 424, and the second valve stem 421 can move along the axial direction of the second insertion tube 424. The second sealing plug 422 is connected to the second valve stem 421, and the second valve stem 421 can drive the second sealing plug 422 to move along the axis of the second valve stem 421. The second sealing plug 422 can close or open the second insertion tube 424. Specifically, the second sealing plug 422 is located in the inner cavity of the second water tank 300. When the second sealing plug 422 abuts against the end of the second insertion tube 424, the second sealing plug 422 seals the second insertion tube 424, causing the second switching valve 420 to be in the closed state. When the second sealing plug 422 disengages from the second insertion tube 424, that is, the second sealing plug 422 does not contact the second insertion tube 424, at this time, the second switching valve 420 is in the open state, the second insertion tube 424 communicates with the inner cavity of the second water tank 300, and the water in the second water tank 300 can flow into the second insertion tube 424 and thus flow out of the second water tank 300.

[0060] It can be understood that the first sealing plug 412 and the second sealing plug 422 can be made of materials such as rubber or silica gel. The first sealing plug 412 is sleeved on the outer periphery of the first valve stem 411. A clamping groove is provided on the outer peripheral wall of the first valve stem 411. The first sealing plug 412 is clamped with the clamping groove of the first valve stem 411 to ensure that the first sealing plug 412 is not easily separated from the first valve stem 411. The second sealing plug 422 is sleeved on the outer periphery of the second valve stem 421. A clamping groove is also provided on the outer peripheral wall of the first valve stem 411. The second sealing plug 422 is clamped with the clamping groove of the second valve stem 421 to ensure that the second sealing plug 422 is not easily separated from the second valve stem 421, enabling the first sealing plug 412 and the second sealing plug 422 to work properly.

[0061] Referring to Figure 8 and Figure 9 As shown, in some embodiments, the first valve core includes a first elastic member 413. The first elastic member 413 can be connected to or abutted against between the first valve stem 411 and the first water tank 200. The first elastic member 413 is used to apply an elastic force to the first valve stem 411. Under the action of the elastic force, the first valve stem 411 presses the first sealing plug 412 against the end of the first insertion tube 414. The first elastic member 413 is used to keep the first sealing plug 412 closed to the first insertion tube 414, that is, to keep the first switching valve 410 in a closed state. Under natural conditions, referring to Figure 9 As shown, the elastic force of the first elastic member 413 keeps the first sealing plug 412 in contact with the end of the first insertion tube 414, thereby closing the first insertion tube 414 and keeping the first switching valve 410 in a closed state. It can also be understood that the first valve stem 411 is in the initial position. At this time, if the rear end of the first valve stem 411 is pressed, the first valve stem 411 can compress the first elastic member 413. At the same time, the first valve stem 411 drives the first sealing plug 412 to move forward, and the first sealing plug 412 will separate from the first insertion tube 414, thereby opening the first insertion tube 414 and switching the first switching valve 410 to the open state. After releasing the first valve stem 411, the elastic force of the first elastic member 413 will cause the first valve stem 411 to automatically reset. Therefore, the first elastic member 413 can be understood as a reset member, enabling the first valve stem 411 to automatically return to the initial position and enabling the first switching valve 410 to automatically return from the open state to the closed state.

[0062] Referring to Figure 6 and Figure 7As shown, in some embodiments, the second valve core includes a second elastic member 423. The second elastic member 423 is connected to or abuts between the second valve stem 421 and the second water tank 300. The second elastic member 423 is used to apply an elastic force to the second valve stem 421. Under the action of the elastic force, the second valve stem 421 presses the second sealing plug 422 against the end of the second insertion tube 424. The second elastic member 423 is used to keep the second sealing plug 422 closed to the second insertion tube 424, that is, to keep the second switching valve 420 in a closed state. Naturally, referring to Figure 7 As shown, the elastic force of the second elastic member 423 keeps the second sealing plug 422 in abutment with the end of the second insertion tube 424, thereby closing the second insertion tube 424 and keeping the second switching valve 420 in a closed state. It can also be understood that the second valve stem 421 is in the initial position. At this time, if the front end of the second valve stem 421 is pressed, the second valve stem 421 can compress the second elastic member 423. At the same time, the second valve stem 421 drives the second sealing plug 422 to move backward, and the second sealing plug 422 will disengage from the second insertion tube 424, thereby opening the second insertion tube 424 and switching the second switching valve 420 to the open state. After releasing the second valve stem 421, the elastic force of the second elastic member 423 will cause the second valve stem 421 to automatically reset. Therefore, the second elastic member 423 can be understood as a reset member, which allows the second valve stem 421 to automatically return to the initial position and allows the second switching valve 420 to automatically return from the open state to the closed state.

[0063] Referring to Figure 3 As shown, when the valve assembly 400 is in the connected state, the first valve stem 411 abuts against the second valve stem 421, the first elastic member 413 and the second elastic member 423 are compressed, and both the first switching valve 410 and the second switching valve 420 are in the open state, so that the first sealing plug 412 opens the first insertion tube 414, and, the second sealing plug 422 opens the second insertion tube 424. At this time, the first insertion tube 414 and the second insertion tube 424 are in communication with each other, and the inner cavities of the first water tank 200 and the second water tank 300 are in communication with each other. Since the first insertion tube 414 and the second insertion tube 424 are connected through the sealing sleeve 415, it can play a sealing role, and when water flows between the first insertion tube 414 and the second insertion tube 424, there will be no water leakage. When the valve assembly 400 is in the separated state, the first valve stem 411 does not contact the second valve stem 421, and both the first switching valve 410 and the second switching valve 420 are in the closed state. Under the action of the elastic forces of the first elastic member 413 and the second elastic member 423, the first sealing plug 412 can be made to close the first insertion tube 414. At this time, the first sealing plug 412 presses against the end of the first insertion tube 414. At the same time, the second sealing plug 422 closes the second insertion tube 424, and the second sealing plug 422 presses against the end of the second insertion tube 424, which can prevent water leakage in the first water tank 200 and the second water tank 300.

[0064] In some other embodiments, without being limited to being connected between the first valve stem 411 and the first water tank 200, the first elastic member 413 can provide an elastic force to the first valve stem 411 in other connection manners. Without being limited to being connected between the second valve stem 421 and the second water tank 300, the second elastic member 423 can provide an elastic force to the second valve stem 421 in other connection manners.

[0065] Referring Figure 8 and Figure 9 As shown, in some embodiments, the first elastic member 413 is set as a spring. The first elastic member 413 is sleeved on the outer periphery of the first valve stem 411. A first boss 4111 is provided on the outer peripheral wall of the first valve stem 411. The first boss 4111 can extend around the axis of the first valve stem 411. The first boss 4111 has an annular structure. The first elastic member 413 is located within the first insertion tube 414. It can be understood that the first insertion tube 414 surrounds the first elastic member 413 and plays a role in limiting the first elastic member 413. One end of the first elastic member 413 abuts against the bottom wall of the first insertion tube 414, and the other end of the first elastic member 413 abuts against the first boss 4111. Such a setting can ensure a relatively stable connection between the first elastic member 413 and the first valve stem 411. Moreover, the occupied space of the first elastic member 413 is small, which is beneficial to the small occupied space of the first switching valve 410. In some other embodiments, the first elastic member 413 can also be set as a shrapnel or other types of elastic structures.

[0066] Referring Figure 6 and Figure 7 As shown, in some embodiments, the second elastic member 423 is set as a spring. The second elastic member 423 is sleeved on the outer periphery of the second valve stem 421. A second boss 4211 is provided on the outer peripheral wall of the second valve stem 421. The second boss 4211 can extend around the axis of the second valve stem 421. The second boss 4211 has an annular structure. The second elastic member 423 is located within the second insertion tube 424. It can be understood that the second insertion tube 424 surrounds the second elastic member 423 and plays a role in limiting the second elastic member 423. One end of the second elastic member 423 abuts against the bottom wall of the second insertion tube 424, and the other end of the second elastic member 423 abuts against the second boss 4211. Such a setting can ensure a relatively stable connection between the second elastic member 423 and the second valve stem 421. Moreover, the occupied space of the second elastic member 423 is small, which is beneficial to the small occupied space of the second switching valve 420. In some other embodiments, the second elastic member 423 can also be set as a shrapnel or other types of elastic structures.

[0067] Referring Figure 3As shown, in some embodiments, the first elastic member 413 applies elastic force to the first valve stem 411 along a first direction, and the second elastic member 423 applies elastic force to the second valve stem 421 along a second direction, and the first direction and the second direction are opposite directions to each other. For example, referring to Figure 3 As shown, the first direction is the rear direction, and the second direction is the front direction. The elastic force of the second elastic member 423 acting on the second valve stem 421 is greater than the elastic force of the first elastic member 413 acting on the first valve stem 411. A limiting boss 210 is provided in the second water tank 300. The limiting boss 210 is located on the side of the second valve stem 421 away from the first valve stem 411, that is, the limiting boss 210 is located on the rear side of the second valve stem 421. When the valve assembly 400 is in a connected state, the end of the second valve stem 421 away from the first valve stem 411 abuts against the limiting boss 210, that is, the rear end of the second valve stem 421 abuts against the limiting boss 210.

[0068] When the second water tank 300 is inserted into the installation position 110 from front to back, the first switch valve 410 and the second switch valve 420 are connected to each other. During the connection process between the first switch valve 410 and the second switch valve 420, first, the front end of the first valve stem 411 abuts against the rear end of the second valve stem 421. At this time, since the elastic force of the second elastic member 423 is greater than the elastic force of the first elastic member 413, when the second water tank 300 moves backward, the second valve stem 421 will drive the first valve stem 411 to move backward, the first elastic member 413 is gradually compressed, and the second valve stem 421 pushes the first valve stem 411 to move backward relative to the first insertion tube 414, while the second valve stem 421 will not move forward relative to the second insertion tube 424. The first valve stem 411 moves until the rear end of the first valve stem 411 contacts the limiting boss 210. At this time, the first sealing plug 412 opens the first plug 414, so that the first switch valve 410 is in an open state. The first valve stem 411 cannot move backward due to the limitation of the limiting boss 210. When the second water tank 300 continues to move backward, the second valve stem 421 is supported by the first valve stem 411, and the second valve stem 421 cannot continue to move backward. The second valve stem 421 moves forward relative to the second plug 424, and the second elastic member 423 is compressed, so that the second sealing plug 422 opens the second plug 424. At this time, the second switch valve 420 is in an open state, and the first water tank 200 is connected with the second water tank 300. Such a setting can ensure that after the second water tank 300 is installed, the first switch valve 410 and the second switch valve 420 can be normally switched to the open state, avoiding the situation that one of the elastic members is too elastic, which makes it difficult to move the corresponding valve stem.

[0069] Reference Figure 2 and Figure 4As shown, in some embodiments, the first housing 100 is provided with a fastening position 120, which can be understood as a card hole or a card slot, and the second water tank 300 is provided with a snap 340, which can be understood as a cantilever structure or a boss structure. When the second water tank 300 is inserted into the installation position 110 and the second water tank 300 is installed in place, the snap 340 is engaged with the fastening position 120, which can clamp the second water tank 300, fix the position of the second water tank 300, keep the above-mentioned first elastic member 413 and second elastic member 423 compressed, so that the valve assembly 400 remains in the connected state, ensuring normal conduction between the inner cavity of the second water tank 300 and the inner cavity of the first water tank 200, and realizing normal water supply. During the process of disassembling the second water tank 300, the snap 340 can be disengaged from the fastening position 120 by pressing the snap 340, so as to facilitate the removal of the second water tank 300. The number of the snaps 340 and the fastening positions 120 can be set to be multiple, so as to fix the first housing 100 and the second water tank 300 at multiple positions.

[0070] Referring to Figure 4 As shown, in some embodiments, the snap 340 can be disposed on the bottom wall of the second water tank 300, the snap 340 is disposed downward, the fastening position 120 is disposed on the bottom wall of the first housing 100. During the process of inserting the second water tank 300 into the installation position 110 from the back to the front, when the second water tank 300 is installed in place, due to the gravity of the second water tank 300, the snap 340 is pressed into the fastening position 120, so as to quickly complete the engagement of the snap 340 with the fastening position 120, and the installation is relatively convenient.

[0071] In some other embodiments, the second water tank 300 and the first housing 100 can also be fixedly connected through structures such as fasteners or locking structures, so that the valve assembly 400 remains in the connected state.

[0072] It should be noted that when the valve assembly 400 is in the connected state, the distance between the first sealing plug 412 and the first insertion tube 414 affects the magnitude of the water flow. The distance between the first sealing plug 412 and the first insertion tube 414 can be used to measure the degree to which the first sealing plug 412 opens the first insertion tube 414. The greater the distance between the first sealing plug 412 and the first insertion tube 414, the greater the degree to which the first sealing plug 412 opens the first insertion tube 414. The distance between the second sealing plug 422 and the second insertion tube 424 also affects the magnitude of the water flow. The distance between the second sealing plug 422 and the second insertion tube 424 can be used to measure the degree to which the second sealing plug 422 opens the second insertion tube 424. The greater the distance between the second sealing plug 422 and the second insertion tube 424, the greater the degree to which the second sealing plug 422 opens the second insertion tube 424. The lengths of the first valve stem 411 and the second valve stem 421, and the distance between the first valve stem 411 and the limit boss 210 can be adaptively set according to the usage situation, so as to adjust the distance between the first sealing plug 412 and the first insertion tube 414 and the distance between the second sealing plug 422 and the second insertion tube 424. Furthermore, the lengths of the first valve stem 411 and the second valve stem 421, and the position of the limit boss 210 can be obtained by using the distance formula. The greater the distance between the first valve stem 411 and the limit boss 210, when the valve assembly 400 is in the connected state, the displacement of the position where the first valve stem 411 abuts against the limit boss 210 compared to the initial position is greater, which can make the degree to which the first sealing plug 412 opens the first insertion tube 414 greater.

[0073] Referring to Figure 7 and Figure 9 As shown, in some embodiments, when the valve assembly 400 is in the separated state, the first valve stem 411 is located inside the sealing sleeve 415, and a part of the structure of the second valve stem 421 extends outside the second insertion tube 424, which is beneficial to observing the position of the first valve stem 411 and facilitating the alignment and installation of the first valve stem 411 and the sealing sleeve 415. In addition, the second switching valve 420 can be checked for normal operation by pressing the second valve stem 421, which is beneficial to performing maintenance operations on the second switching valve 420.

[0074] Referring to Figure 5 As shown, in some embodiments, the second water tank 300 includes an outer peripheral wall. The outer peripheral wall of the second water tank 300 is arranged around an axis parallel to the height direction of the humidifying device 1000. The height direction of the humidifying device 1000 is Figure 1 and Figure 5The up - down direction, that is, the outer peripheral wall of the second water tank 300 is arranged around an axis parallel to the up - down direction, and a part of the structure of the outer peripheral wall of the second water tank 300 is recessed inward to form the first groove 311. When the valve assembly 400 is in the connected state, the first water tank 200 is placed inside the first groove 311, that is, at least part of the structure of the first water tank 200 is located inside the first groove 311. The first groove 311 can be understood as being used to avoid the first water tank 200 and can play a role of making way. After setting the first groove 311, the overall size of the first water tank 200 and the second water tank 300 in the front - back direction can be reduced, thereby reducing the occupied space of the humidifying device 1000 and being beneficial to the miniaturization of the humidifying device 1000. Specifically, the first groove 311 is located at the rear side of the second water tank 300. When the second water tank 300 is inserted into the installation position 110 from front to back, the first water tank 200 just inserts into the first groove 311, which is also beneficial to the positioning and installation of the second water tank 300.

[0075] Refer to Figure 6 and Figure 7 As shown, in some embodiments, a second groove 312 is formed on the side wall of the first groove 311. The second groove 312 can be understood as being formed by a part of the structure of the side wall of the first groove 311 being recessed inward into the inside of the second water tank 300. The second insertion tube 424 is located inside the second groove 312, which can prevent the second insertion tube 424 from protruding outside the second water tank 300. And when the valve assembly 400 is in the connected state, since the second insertion tube 424 is inserted into the sealing sleeve 415, at least part of the structure of the sealing sleeve 415 can be located inside the second groove 312. It can be understood that the second groove 312 is used to avoid the second insertion tube 424 and the sealing sleeve 415 and plays a role of making way. After setting the second groove 312, the overall size of the first water tank 200 and the second water tank 300 in the front - back direction can be reduced, thereby reducing the occupied space of the humidifying device 1000 and being beneficial to the miniaturization of the humidifying device 1000.

[0076] Refer to Figure 7 As shown, in some embodiments, the second insertion tube 424 is located at the lower position of the second water tank 300, and the second groove 312 is also correspondingly arranged at the lower position of the second water tank 300. A notch communicating with the second groove 312 is formed on the bottom wall of the second water tank 300. After removing the second water tank 300 from the installation position 110 and turning the second water tank 300 over, the second insertion tube 424 can be observed through this notch, so as to see the state of the second switching valve 420, which is beneficial to judging whether the second switching valve 420 leaks water and performing maintenance operations on the second switching valve 420 accordingly.

[0077] Refer to Figure 5As shown, in some embodiments, the second water tank 300 includes a second housing 310, a cover 320, and a water injection cover 330. An opening 321 is provided at the upper end of the second housing 310. The cover 320 is detachably connected to the opening 321. The cover 320 is formed with a water injection port 331. The water injection cover 330 is detachably connected to the water injection port 331. The volume of the water injection cover 330 is smaller than that of the cover 320, and the opening 321 is larger than the water injection port 331. When it is necessary to replenish water to the second water tank 300, only the second water tank 300 needs to be pulled out from the installation position 110, and then the water injection cover 330 is disassembled, so that the water injection port 331 can be opened. At this time, water can be added to the second water tank 300 through the water injection port 331. When it is necessary to clean the second water tank 300, only the cover 320 needs to be disassembled to open the opening 321. Since the shape of the opening 321 is larger, it is convenient for the user to reach into the opening 321 to clean the inner cavity of the second water tank 300, which is beneficial to cleaning the inner cavity of the second water tank 300 cleanly and can improve the user experience. In some embodiments, a sealing connection can be achieved between the cover 320 and the second housing 310 through a sealing ring, and a sealing connection can be achieved between the water injection cover 330 and the cover 320 through a sealing ring.

[0078] In some embodiments, the cover 320 can be connected to the opening 321 through structures such as buckles, and the water injection cover 330 can be connected to the water injection port 331 through structures such as buckles. When disassembling the cover 320 or the water injection cover 330, the operation is relatively convenient.

[0079] Referring to Figure 5 As shown, in some embodiments, the second water tank 300 is provided with a handle portion 350. The handle portion 350 and the first water tank 200 are respectively located at both ends of the second water tank 300 along the third direction. The water injection port 331 communicates with the inner cavity of the second water tank 300. The water injection port 331 and the handle portion 350 are respectively located at both ends of the second water tank 300 along the fourth direction. The third direction and the fourth direction are perpendicular to each other, and the third direction and the fourth direction are respectively perpendicular to the height direction of the humidifying device 1000. Such a setting can make full use of the space of the second water tank 300 in the third direction and the fourth direction. Referring to Figure 1 and Figure 3As shown, the third direction is the left - right direction, and the fourth direction is the front - back direction. The handle part 350 is located on the front side of the second water tank 300, and the first water tank 200 is located on the rear side of the second water tank 300. The installation position 110 is an installation groove. The second water tank 300 is inserted into the installation position 110 from front to back. The handle part 350 is arranged facing the notch of the installation position 110, which is convenient for users to quickly observe the position of the handle part 350. At the same time, during the installation process of the second water tank 300, the first groove 311 on the rear side of the second water tank 300 can also be aligned and cooperate with the first water tank 200, which is convenient for positioning and installing the second water tank 300. In this embodiment, by reasonably arranging the position of the water injection port 331, the water injection port 331 is located at the edge of the cover body 320. Even in the case of a small water - adding space, it is also convenient to add water. In some embodiments, due to the reasonable arrangement of the position of the water injection port 331, when the second water tank 300 is installed in the installation position 110, the water injection cover 330 is not blocked by the housing 310 or other components. At this time, it is not necessary to take out the second water tank 300 from the installation position 110. After directly disassembling the water injection cover 330, the water injection port 331 can be opened, which is convenient for adding water to the second water tank 300. In some embodiments, the handle part 350 can be set as a convex structure, which is convenient for users to hold. In some other embodiments, the handle part 350 can be set as a groove, which can reduce the occupied space of the second water tank 300.

[0080] Referring to Figure 5 As shown, in some embodiments, the corners of the second water tank 300 are provided with rounded corners, and the water injection port 331 is located at the rounded corners, making the water injection port 331 closer to the corners of the second water tank 300, which can make full use of the space of the second water tank 300. The first groove 311 can be understood as being formed by recessing inward from a corner of the second water tank 300. Let the first water tank 200 be located at the corner of the second water tank 300, which can make full use of the space of the second water tank 300. And when the water - adding space is small, it is also convenient to add water. Specifically, the inner wall of the first groove 311 includes two mutually perpendicular side walls, and the shape of the first water tank 200 corresponds to the shape of the first groove 311.
