Modes for Carrying Out the Invention

[0053] It should be noted that if directional indications are involved in the embodiments of the present application, such directional indications are only used to explain the relative positional relationship, movement status, etc. between the components under a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0054] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present application, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the meaning of "and / or" appearing throughout the text is to include three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which both A and B are satisfied.

[0055] In the prior art, a humidifying device usually includes a water tank and a humidifying device. The water tank is used to supply water to the humidifying device, and the humidifying device is used to convert the water in the water tank into water mist and spray it out to improve the air humidity in the target environment. A water level control system needs to be set in the water tank, and the humidifying device usually needs to be equipped with electrically charged functional components such as a fan and an oscillating plate. In order to ensure that the water mist of the humidifying device is clean enough, the user needs to clean the water tank frequently. Many of these electrically charged functional components are set in the water tank, and the traditional water level control system has a complex structure, which requires the user to avoid these electrically charged components when cleaning the water tank, making cleaning troublesome and incomplete. In addition, these electrically charged functional components are also prone to water ingress during the user's cleaning of the water tank, causing damage and reducing the service life of the humidifying device.

[0056] To solve the above technical problems, please refer to Figures 1 to 8. The present application provides a humidifying device 100. The humidifying device 100 includes a box assembly 10 and a humidifying assembly 30. The box assembly 10 is formed with a cavity 20 for storing water, and the humidifying assembly 30 can be detachably installed on the box assembly 10. In this embodiment, the specific shape and material of the box assembly 10 are not limited, as long as the cavity 20 can be formed and water can be stored in the cavity 20. The humidifying assembly 30 is used to convert the water stored in the cavity 20 into water mist and spray the water mist into the room to improve the indoor air humidity and make the people indoors feel comfortable. Specifically, in this embodiment, referring to FIG. 2 , the humidifying assembly 30 can be detached from the housing assembly 10 as a whole. Specifically, the humidifying assembly 30 includes a fan component 31 and an atomizing component 32, which are integrally arranged or interconnected. The atomizing component 32 is used to atomize the water in the cavity 20 to form a mist, and the fan component 31 is used to drive the mist into the room. The type of the atomizing component 32 is not limited. In one embodiment, the atomizing component 32 includes an oscillating plate that is used to ultrasonically oscillate to generate the mist. In other embodiments, the atomizing component 32 can also be a cold evaporation or hot evaporation atomizer. The fan component 31 primarily includes a motor and a wind wheel. When the humidifying device 100 is in operation, the atomizing component 32 generates mist, and the motor is used to drive the wind wheel to rotate, generating an airflow to blow the mist in the cavity 20 out of the cavity 20 and into the room, thereby increasing the moisture content in the room and raising the indoor air humidity.

[0057] It should be noted that the descriptions of direction and orientation in this application refer only to the state of the humidifier 100 after installation and during normal use, and do not include the state of the humidifier 100 during production, transportation, installation, and sales. In this embodiment, the vertical direction refers to the direction generally parallel to gravity. The horizontal direction refers to the direction generally perpendicular to the vertical direction.

[0058] The atomizing component 32 and the fan component 31 may be integrally provided in various ways, such as being integrally formed or being formed by bonding multiple components together. As long as the humidifying assembly 30 as a whole can be connected to the housing assembly 10 in an easily detachable manner, for example, the humidifying assembly 30 can be snap-fitted to the housing assembly 10 so that the humidifying assembly 30 as a whole can be detached from the housing assembly 10.

[0059] In the embodiment provided in the present application, the fan component 31 and the atomizing component 32, which are electrically charged functional components in the humidifying device 100, are integrated into a humidifying assembly 30. The humidifying assembly 30 can be completely separated from the water storage box assembly 10 as a whole. When the user needs to clean the box assembly 10, they only need to conveniently remove the humidifying assembly 30 as a whole from the box assembly 10, and can easily and thoroughly clean the water tank 11 assembly without having to avoid the electrically charged components such as the atomizing component 32 or the fan component 31. This can also prevent the electrically charged components in the humidifying device 100 from being infiltrated with water during the user's cleaning of the water tank 11 assembly, thereby extending the service life of the humidifying device 100.

[0060] Based on the previous embodiment, please continue to refer to Figure 3. The fan component 31 is used to transport airflow toward the atomizing component 32 along a first direction, and after the airflow reaches the atomizing component 32, it drives the water mist to flow into the room along a second direction. The first direction is the radial direction of the fan component 31. In this embodiment, the first direction is different from the second direction. As a result, the flow direction of the water mist is different from the air outlet direction of the fan component 31. The water mist will basically not flow back to the fan component 31, thereby ensuring that the fan component 31 is dry and not easily damaged by the water mist, and has better reliability. In one embodiment, the first direction is from top to bottom, while the second direction is from bottom to top. Moreover, in this embodiment, the first direction is the radial direction of the fan component 31. The specific type of the fan component 31 is not limited. In one embodiment, the fan component 31 is a centrifugal fan, which has a smaller volume and a larger air supply volume.

[0061] Based on the previous embodiment, please continue to refer to Figures 2 and 3. The humidifying assembly 30 also includes an air duct wall 33 connecting the fan component 31 and the atomizing component 32. The air duct wall 33 forms an air duct 330 for connecting the cavity 20 and the indoor space, so that the water mist flows into the indoor space along the air duct 330. It can be understood that in order to allow the water mist generated by the atomizing component 32 atomizing the water stored in the cavity 20 to flow smoothly into the indoor space, the humidifying device 100 should have an air duct 330. When the fan component 31 is in operation, the airflow generated flows along the air duct 330, driving the water mist to flow along the air duct 330. The air duct 330 has an outlet connected to the indoor space, so that the water mist is blown into the indoor space along the air duct 330. The structure and material of the air duct wall 33 are not limited, as long as they can form the air duct 330 connected to the indoor space. The air duct 330 should be connected to the cavity 20 and / or have an inlet for the water mist to enter the air duct 330. The water mist in the air duct 330 is blown into the indoor space by the airflow generated by the fan component 31. Due to the wind pressure generated by the fan component 31, the water mist can be transported to a location far away from the humidifier 100, thereby rapidly and widely increasing the indoor humidity.

[0062] Based on the previous embodiment, please continue to refer to Figures 2 and 3. In this embodiment, the air duct wall 33 extends in the vertical direction, the fan component 31 is located at the upper end of the air duct wall 33, and the atomizing component 32 is located at the lower end of the air duct wall 33.

[0063] It should be noted that the descriptions of direction and orientation in this application refer only to the state of the humidifier 100 after installation and during normal use, and do not include the state of the humidifier 100 during production, transportation, installation, and sales. In this embodiment, the vertical direction refers to the direction generally parallel to gravity. The horizontal direction refers to the direction generally perpendicular to the vertical direction.

[0064] In this embodiment, it can be understood that the water in the box assembly 10 is generally located at the lower end of the box assembly 10 due to gravity, and therefore the atomizing component 32 should also be located at the lower end of the box assembly 10 to facilitate contact with the water stored in the box and convert the water stored in the box into water mist. The fan assembly only needs to be located at a position that can deliver airflow into the air duct 330 so that wind pressure is generated in the air duct 330. In order to extend the service life of the fan assembly, the fan component 31 is located at the upper end of the air duct wall 33, and the atomizing component 32 is located at the lower end of the air duct wall 33, so that the fan component 31 is located far away from the area where water mist is generated, so that the water mist generated by the atomizing component 32 is not easy to flow into the fan component 31. It is understood that the fan component 31 is typically equipped with precision live components such as a motor. If these components come into contact with water mist and become damp, they are prone to malfunction, which can affect the service life of the humidifier 100 or cause unstable operation of the humidifier 100. Therefore, in this embodiment, the fan component 31 is located above the atomizing component 32. On the one hand, it is farther away from the area where the water mist is generated, and on the other hand, it is farther away from the water stored in the box assembly 10. This can reduce the probability of the fan component 31 malfunctioning due to moisture, thereby extending the service life of the humidifier 100 and ensuring stable operation of the humidifier 100.

[0065] The air duct wall 33 extends in the vertical direction as a whole, and its shape is not limited. In one embodiment, please continue to refer to Figures 2 and 3. The air duct wall 33 is a hollow cylindrical structure as a whole. The air duct 330 is formed in the cylindrical air duct wall 33, and the fan component 31 is connected to the upper end of the air duct wall 33. In one embodiment, the humidifying component is connected to the lower end of the air duct wall 33 and is also screwed to the air duct wall 33. The water mist generated by the atomizing component 32 flows along the air duct 330 under the action of the airflow generated by the fan component 31, and then flows into the room. It is sent to a place far away from the humidifying device 100, so that the indoor humidity can be increased quickly and over a large range.

[0066] The specific shape of the air duct 330 can be various, as long as it is connected to the room, and the airflow generated by the fan component 31 and the water mist generated by the atomizer can enter the air duct 330. In one embodiment, the mist outlet 101 of the humidifying device 100 is located above the humidifying device 100. In order to separate the mist outlet 101 and the fan component, in this embodiment, please continue to refer to Figure 3. The air duct 330 includes a first air supply section 331 and a second air supply section 332 arranged in sequence along the air supply direction. The air inlet of the first air supply section 331 and the air outlet of the second air supply section 332 are both located at the upper end of the air duct wall 33. The fan component 31 is provided at the air inlet of the first air supply section 331. The adjacent portion of the first air supply section 331 and the second air supply section 332 is located at the lower end of the air duct wall 33 and is provided with the atomizing component 32. In this embodiment, the first air supply section 331 and the second air supply section 332 are roughly arranged side by side, and the air duct wall 33 has a partition extending up and down, and the partition is arranged between the first air supply section 331 and the second air supply section 332. Among them, the fan component 31 is located at the air inlet of the first air supply section 331, and transports airflow from top to bottom to the first air supply section 331. The atomizing component 32 is located at the lower end of the first air supply section 331 and the second air supply section 332, and is located at the junction of the first air supply section 331 and the second air supply section 332. In the process of flowing from the first air supply section 331 to the second air supply section 332, the airflow encounters the water mist and drives the water mist to be transported from bottom to top along the second air supply section 332, and finally blown out from the mist outlet 101 and blown into the room. In this embodiment, the airflow generated by the fan component 31 encounters water mist only after passing through the first air supply section 331, and the water mist is sent away along the second air supply section 332 separated from the first air supply section 331. In this way, it is difficult for water mist to enter the first air supply section 331 and contact the fan component 31. Moreover, since the first air supply section 331 extends up and down as a whole, whether it is water mist or water stored in the box assembly 10, it is difficult to flow along the first air supply section 331 to the fan component 31. In this way, the fan component 31 and the water or water mist can be well separated, thereby keeping the fan component 31 dry, improving the reliability of the fan component 31, and further extending the service life of the humidifier.

[0067] Furthermore, in one embodiment, referring to Figures 3, 7 and 8, the humidifying device 100 further includes a guide ring 40, which is provided in the second air supply section 332 and is located above the atomizing component 32. The guide ring 40 has a through hole 41 extending along the up and down direction. In this embodiment, the guide ring 40 is provided on the path of water mist oscillation transmission, and its shape is annular. When the atomizing component 32 is working, it plays a role in gathering water mist, reducing internal flow loss, and increasing the humidification amount. In addition, the guide ring 40 can also receive the water droplets generated by the water mist gathering above, to prevent the water droplets from directly dripping onto the water surface at the atomizing component 32, affecting the operation of the atomizing component 32. It can also reduce the dripping sound produced by the water droplets falling onto the water surface.

[0068] It can be understood that the size of the through hole 41 should be set within an appropriate range. If the through hole 41 is too small, it may affect the flow rate of the water mist, causing the water mist to be unable to be smoothly sent to a place far away from the humidifier 100, but to gather at the mist outlet 101, affecting the use effect of the humidifier 100. If the through hole 41 is set too large, it cannot play a good gathering role, cannot reduce internal flow losses, and cannot increase the humidification amount. Therefore, in one embodiment, please refer to Figure 9, the atomizing component 32 includes an oscillation plate, the inner diameter of the oscillation plate is R, and the inner diameter R1 of the through hole 41 is greater than or equal to 1.1R and less than or equal to 1.5R, so that the through hole 41 can effectively reduce internal flow losses and increase humidification without significantly reducing the flow rate of the water mist.

[0069] In one embodiment, the atomizing component 32 includes an oscillating plate, and the distance H1 between the bottom of the guide ring 40 and the upper side of the oscillating plate is greater than or equal to 20 mm and less than or equal to 40 mm. In this way, the guide ring 40 will not affect the flow of the water mist due to being set too low, nor will it fail to play a gathering role due to being set too high.

[0070] In another embodiment, the vertical dimension H of the through hole 41 is greater than or equal to 10 mm and less than or equal to 20 mm. In this way, the water mist can be well gathered within this height range and continue to rise.

[0071] It should be noted that the above three embodiments can be implemented separately or in combination.

[0072] Based on the above embodiment, please continue to refer to Figures 7 and 8. To further reduce the dripping sound of water droplets generated by the accumulation of water mist, a plurality of drainage ribs 42 are provided on the upper side of the guide ring 40. The plurality of drainage ribs 42 are spaced apart along the circumference of the through hole 41. The shape of the drainage ribs 42 is not limited, as long as they can reduce the flow rate of the water droplets. In this way, the dripping sound generated by the water droplets is reduced, and the user experience of the humidifier 100 is improved.

[0073] In one embodiment, referring to FIG8 , each drainage rib 42 is strip-shaped, and the length direction of each drainage rib 42 extends along the circumference of the through hole 41. The number of drainage ribs 42 is preferably greater than or equal to 4 and less than or equal to , thereby effectively reducing the flow rate of large water droplets, reducing the dripping sound produced by the water droplets, and improving the user experience of the humidifier 100.

[0074] On the basis of the above embodiment, please continue to refer to Figures 2 to 4. The box assembly 10 includes a water tank 11 and a cover 12. The water tank 11 forms the cavity 20 with an upper opening. The cover 12 is provided on the upper side of the water tank 11. A mist outlet 101 is formed on the cover 12. The mist outlet 101 is connected to the air duct 330 so that the water mist flows into the room through the mist outlet 101. It can be understood that in other embodiments, the mist outlet 101 can also be formed in the humidification assembly 30. In this embodiment, the mist outlet 101 is provided on the cover 12, and the cover 12 covers the opening on the upper side of the water tank 11, which plays a role in protecting the water tank 11 to prevent the water stored in the water tank 11 from spilling out and reducing the situation where impurities fall into the water tank 11. The water quality of the water stored in the water tank 11 is better and suitable for atomization and humidification. When it is necessary to clean the water tank 11, the cover 12 can be opened to pour out the stored water for easy cleaning. When it is necessary to add water, the cover 12 can also be opened to add water.

[0075] There is no restriction on the shape and size of the mist outlet 101. It is understandable that if the size of the mist outlet 101 is set too large, it is easy to cause insufficient mist outlet height. After the humidifier 100 has been running for a long time, the water mist will easily wet the surrounding area of ​​the mist outlet 101. If the size of the mist outlet 101 is too small, a water film will form at the mist outlet 101, causing the water mist to be unable to be delivered. Therefore, in one embodiment, please refer to Figure 6, the mist outlet 101 is long, specifically, it can be a long strip, such as a rectangle. The width D of the mist outlet 101 is greater than or equal to 4 mm and less than or equal to 7 mm. Within this size range, the water mist can flow out of the mist outlet 101 smoothly, and at the same time has a higher mist outlet height, and the water mist is not easy to wet the humidifier 100. It should be noted that the minimum inner diameter of the mist outlet 101 is the minimum size of the cross section of the mist outlet 101 in the mist outlet direction. In one embodiment, the mist outlet 101 is elongated, and the inner diameter of the mist outlet 101 in the short side direction is the minimum inner diameter of the mist outlet 101 .

[0076] In one embodiment, please continue to refer to Figures 4 to 6. In this embodiment, a mist barrier 50 is provided between the atomizing component 32 and the mist outlet 101. The vertical projection area of ​​the mist duct at the mist barrier 50 is S, and the vertical projection area of ​​the mist barrier 50 is greater than or equal to 0.5S. The vertical projection area of ​​the mist duct at the mist barrier 50 refers to the total cross-sectional area of ​​the water mist passing through the mist barrier 50. The mist barrier 50 serves to disperse the water mist, thereby reducing the proportion of large-particle water droplets at the mist outlet 101 and preventing large-particle water mist from wetting the surrounding area of ​​the humidifier 100 when the humidifier 100 is in operation.

[0077] In one embodiment, referring to Figures 1 to 3 , the humidifying assembly 30 is sandwiched between the cover 12 and the water tank 11 and is at least partially contained within the cavity 20. In this embodiment, when the water tank 11 needs to be cleaned, the cover 12 can be removed, the humidifying assembly 30 can be taken out, and the cover 12 and the water tank 11 can be easily cleaned.

[0078] In one embodiment, a water inlet 102 is further provided on the cover 12 , so that when adding water to the water tank 11 , there is no need to open the cover 12 , which makes the operation more convenient.

[0079] Furthermore, in one embodiment, referring to FIG3 , the cavity 20 includes a first cavity 21 and a second cavity 22 spaced apart in the transverse direction, a valve body assembly 60 is provided between the first cavity 21 and the second cavity 22, the cover 12 is provided with a water inlet 102 corresponding to the upper portion of the first cavity 21, the humidifying assembly 30 is at least partially accommodated in the second cavity 22, and the mist outlet 101 is located above the second cavity 22. It is understood that in this embodiment, a large amount of water can be stored in the first cavity 21, while the water level in the second cavity 22 can be controlled by the valve body assembly 60 and maintained at a certain level, so as to facilitate the atomizing component 32 to atomize the water in the auxiliary water tank 11 and generate water mist.

[0080] Referring to Figures 10 to 12 , in one embodiment, the structure of a humidifying device 100 provided herein is shown. The humidifying device 100 may be a humidifier, a garment steamer, or another type of water level control system having a first chamber 102 and a second chamber 103, and replenishing water from the first chamber 102 to the second chamber 103. Specifically, in this embodiment, the humidifying device 100 includes a water tank 11 and a valve assembly 10. The water tank 11 forms a first chamber 102 and a second chamber 103 that are distributed laterally. The valve assembly 10 is disposed between the first chamber 102 and the second chamber 103.

[0081] In one embodiment, the humidifying device 100 is a humidifier, and an atomizer is provided in the second chamber 103. The first chamber 102 replenishes water to the second chamber 103 through the valve body assembly 10, so that the water level in the second chamber 103 is controlled within a certain range, which is conducive to the operation of the atomizer. In a traditional humidifier, the first chamber 102 and the second chamber 103 are distributed up and down, while in this embodiment, the first chamber 102 and the second chamber 103 are distributed at intervals in the transverse direction. In the prior art, the first chamber 102 and the second chamber 103 are usually distributed in the up and down directions, while in this application, the positional relationship between the first chamber 102 and the second chamber 103 is a laterally spaced distribution. Please refer to Figure 10, in which the valve body assembly 10 is in an open state, and the direction of water flow when the first chamber 102 replenishes water to the second chamber 103 is shown in the figure. In this embodiment, in order to realize water replenishment from the first cavity 102 to the second cavity 103 and to achieve more precise control of the water level in the second cavity 103 , the present application further provides a valve body assembly 10 .

[0082] Referring to Figures 10 to 12 , in the present application, the valve body assembly 10 is installed between the first chamber 102 and the second chamber 103, so that the first chamber 102 replenishes water to the second chamber 103 through the valve body assembly 10. In one embodiment, a partition 23 is provided between the first chamber 102 and the second chamber 103. The specific structure of the partition 23 is not limited, as long as it is used to separate the first chamber 102 and the second chamber 103 and connect the first chamber 102 and the second chamber 103 through a through hole in the partition 23. The valve body assembly 10 is installed on the partition 23 and inserted into the through hole. It is understood that in other embodiments, the valve body assembly 10 can be installed in a variety of ways, as long as the first chamber 102 replenishes water to the second chamber 103 through the valve body assembly 10 and the water level in the second chamber 103 is controlled by the valve body assembly 10.

[0083] Continuing with Figures 10 to 12 , in this embodiment, the valve body assembly 10 includes a first valve body component 11 and a second valve body component 62. The first valve body component 11 is formed with a channel 63, which is used to connect the first cavity 102 with the second cavity 103. The second valve body component 62 is rotatably disposed relative to the first valve body component 11. The second valve body component 62 includes a float 80 and a sealing member 81. The float 80 is configured to rise and fall with changes in the water level of the second cavity 103. The sealing member 81 rotates between a first working position and a second working position as the float 80 rises and falls. The sealing member 81 blocks the channel 63 in the first working position and opens the channel 63 in the second working position.

[0084] In the embodiments provided herein, the specific shape of the channel 63 is not limited, as long as it connects the first chamber 102 and the second chamber 103. In some cases, the water stored in the first chamber 102 flows through the channel 63 to the second chamber 103, supplying water to the second chamber 103 and causing the water level in the second chamber 103 to rise. Water-consuming components within the second chamber 103, such as the atomizer in a humidifier or the steam generator in a garment steamer, consume the water in the second chamber 103, causing the water level in the second chamber 103 to drop. The specific structural material of the float 80 is not limited; for example, it can be a hollow rubber ball, a silicone ball, or a lightweight material with high buoyancy, such as foam. The buoyancy of the float 80 changes with the water level in the second chamber 103, and the rise and fall of the water level in the second chamber 103 drives the float 80 up and down.

[0085] In this embodiment, referring to Figure 10 , the first valve body is rotatably mounted. The rotational mounting method of the first valve body is not limited; for example, the first valve body can be rotationally fixed to the water tank 11 or the second valve body. Because the seal 81 and the float 80 are both mounted on the second valve body, the rise and fall of the float 80 causes the second valve body to rotate, which in turn causes the seal 81 to rotate and change position. Specifically, when the water level within the second chamber 103 rises to a certain height, such as the first liquid level, the float 80 rises, causing the seal 81 to rotate to the first operating position and seal the passage 63. At this point, the water in the first chamber 102 no longer flows into the second chamber 103. If the water-consuming components in the second chamber 103 operate, the water level in the second chamber 103 will drop. When the water level in the second chamber 103 drops to a certain height, such as the second liquid level, the float 80 lowers, driving the seal 81 to rotate to the second operating position, opening the channel 63, and allowing the water in the first chamber 102 to flow into the second chamber 103, raising the water level in the second chamber 103. It can be understood that the first liquid level is higher than the second liquid level. When the water level in the second chamber 103 rises to the first liquid level again, the channel 63 is blocked again. In this way, the water level in the second chamber 103 is controlled between the first and second liquid levels, effectively controlling the water level in the second chamber 103.

[0086] It should be noted that, in the present embodiment, since the second valve body component 62 is rotatably installed, the seal 81 rotates with the rise and fall of the float 80. The presence of the rotating force arm amplifies the effect of the buoyancy change of the float 80 on the movable stroke of the seal 81, so that even a relatively small water level change can drive the seal 81 to move between the first working position and the second working position. Specifically, compared with other technical solutions that directly open or block the channel 63 by raising and lowering the float 80, the structure of the valve body assembly 10 in the present embodiment makes the liquid level difference between the first liquid level and the second liquid level smaller, that is, it achieves more precise control of the water level in the second cavity 103, and the overall structure of the second valve body assembly 10 is simple, reliable and easy to maintain.

[0087] In one embodiment, referring again to FIG. 10 , the second valve body component 62 has a rotating end and a free end that rotates up and down about the rotating end. The float 80 is disposed at the free end, and the sealing member 81 is located between the rotating end and the free end. In this embodiment, the sealing member 81 rotates upward as the float 80 rises and rotates downward as the float 80 descends. In the first operating position, the sealing member 81 upwardly blocks the passage 63, and the buoyancy strengthens the sealing performance of the sealing member 81 against the passage 63. In other embodiments, the rotating end may be located between the sealing member 81 and the float 80. In this manner, the sealing member 81 rotates downward as the float 80 rises and rotates upward as the float 80 descends. In the first operating position, the sealing member 81 downwardly blocks the passage 63. This facilitates opening the passage 63 when the liquid level in the second chamber 103 rises.

[0088] Based on the above embodiment, please continue to refer to Figures 10 to 12. The first valve body component 11 includes an elastic water-sealing component 70. In this embodiment, the elastic water-sealing component 70 is a structure made of a material having elastic deformation properties and a certain sealing property, and can cooperate with the sealing member 81 to block the flow of water between the first cavity 102 and the second cavity 103. In this embodiment, the elastic water-sealing component 70 forms the channel 63. In the first working position, the sealing member 81 presses against the water outlet end 90 of the channel 63, causing the elastic water-sealing component 70 to deform under pressure. That is to say, in this embodiment, when the channel 63 is blocked, the elastic water-sealing component 70 is compressed and deformed, and has a certain reaction force on the sealing member 81. On the one hand, the fit between the sealing member 81 and the elastic water-sealing component 70 is tighter, and the sealing performance is better. On the other hand, when the water level drops and the buoyancy decreases, the reaction force of the elastic sealing member 81 recovers and acts on the sealing member 81, so that the sealing member 81 is easier to be bounced open, and the water flow can enter the channel 63 more smoothly. The valve body assembly 10 can also control the water level in the second cavity 103 more accurately.

[0089] The elastic water sealing component 70 and / or the sealing component 81 can be made of various materials, for example, they can both be rubber or silicone. In one embodiment, the elastic water sealing component 70 and the sealing component 81 are both made of silicone, which has good durability, safe ingredients, easy cleaning, and is not prone to bacterial growth.

[0090] Based on the previous embodiment, please continue to refer to Figure 10. In one embodiment, the channel 63 has a water outlet section 91 adjacent to the water outlet end 90 and extending vertically. The sealing member 81 is located below the water outlet section 91 and presses upward against the water outlet section 91 in the first working position. The inner diameter of the water outlet section 91 is at least partially arranged to gradually expand and then gradually contract from top to bottom. In this embodiment, it can be seen that the elastic water sealing member 70 is drum-shaped in the water outlet section 91. As a result, the elastic water sealing member 70 is more easily compressed and deformed upward when the sealing member 81 presses against the water outlet end 90 of the channel 63, thereby accumulating greater elastic force and improving the sealing performance of the channel 63.

[0091] It is understood that when the valve body assembly 10 is used in household appliances such as humidifiers or evaporators, it is preferably designed to be easily disassembled for cleaning by the user. This prevents the valve body assembly 10 from breeding bacteria and affecting the user's health due to long-term use, or from becoming clogged with scale and affecting its water level control performance. To this end, in one embodiment, the first valve body component 11 is detachably mounted on the partition 23 between the first cavity 102 and the second cavity 103. In this way, when the user desires to thoroughly clean the first valve body component 11, the first valve body component 11 can be removed from the water tank 11, allowing the elastic water sealing component 70 to be easily cleaned.

[0092] In one embodiment, the entire valve body assembly can be removed from the partition 23. This not only facilitates installation of the valve body assembly 10, but also allows the entire valve body assembly 10 to be removed from the water tank 11 for thorough cleaning to prevent bacterial growth that could affect user health, or scale clogging that could affect water level control. To this end, in one embodiment, the first valve body component 11 has a mounting portion, and the second valve body component 62 has a mounting mating portion. The second valve body component 62 is rotatably mounted to the first valve body component 11 through the mating engagement of the mounting portion and the mounting mating portion. In this manner, the second valve body component 62 is rotatably mounted to the first valve body component 11 rather than the water tank 11, allowing the entire valve body assembly 10 to be removed from the water tank 11 for maintenance.

[0093] Based on the previous embodiment, one of the mounting portion and the mounting mating portion is a rotating shaft 103, and the other is an open slot 104 for the rotating shaft 103 to engage. In one embodiment, the open slot 104 is provided on the first valve body component 11, and the rotating shaft 103 is provided at the rotating end of the second valve body component 62, so that the second valve body component 62 is rotatably mounted on the first valve body component 11. Due to the design of the open slot 104, the first valve body component 11 and the second valve body component 62 can be easily disassembled. When the valve body assembly 10 needs to be maintained and cleaned, the first valve body component 11 can be removed from the water tank 11, and then the first valve body component 11 and the second valve body component 62 can be separated. After the first valve body component 11 and the second valve body component 62 are thoroughly cleaned, the first valve body component 11 and the second valve body component 62 can be assembled first, and then the first valve body component 11 can be installed on the water tank 11. In this way, the installation operation is facilitated, and the valve body assembly 10 can be cleaned more easily to avoid bacterial growth.

[0094] In one embodiment, referring to Figure 10 , the first valve body component 11 includes a tubular portion 71. The tubular portion 71 is configured to be inserted into the through hole of the partition 23, with a first end located in the first cavity 102 and a second end located in the second cavity 103. The elastic water-sealing component 70 is disposed at the second end. In this manner, the first valve body component 11 is removably mounted on the water tank 11. The tubular portion 71 includes a hollow core. The elastic water-sealing component 70 is mounted at the second end of the tubular portion 71, and the channel 63 therein communicates with the core to achieve communication between the first cavity 102 and the second cavity 103. In this manner, the first valve body component 11 and the partition 23 are removably mounted using a simple structure. In one embodiment, the tubular portion 71 extends laterally.

[0095] The elastic water-sealing component 70 can be connected to the tubular portion 71 in a variety of ways, such as by snapping or threading. In this embodiment, the elastic water-sealing component 70 is removably inserted into the tubular portion 71. Specifically, the elastic water-sealing component 70 can be sleeved within the core of the tubular portion 71, or it can be sleeved around the outer periphery of the tubular portion 71. In this way, the elastic force of the elastic water-sealing component 70 securely connects the elastic water-sealing component 70 and the tubular portion 71, resulting in a simple structure and easy disassembly and assembly. This allows the elastic water-sealing component 70 and the tubular portion 71 to be disassembled and cleaned separately when cleaning the first valve body component 11, providing a more thorough cleaning. Furthermore, in one embodiment, the elastic water-sealing component 70 includes a transversely extending sleeve section and a vertically extending water outlet section 91. The sleeve section and the water outlet section 91 are integrally formed, ensuring that the elastic water-sealing component 70 has excellent sealing properties and is more durable and reliable.

[0096] In order to better fix the first valve body component 11 and the water tank 11, in one embodiment, please continue to refer to Figures 1 to 3. A baffle 72 is convexly provided on the outer periphery of the tubular portion 71, and the first valve body component 11 also includes a fixing portion, which is used to detachably connect the first end so that the partition 23 is clamped between the fixing portion and the baffle 72. In this embodiment, when installing the first valve body component 11, the second end of the tubular portion 71 can be grasped, and the tubular portion 71 can be inserted and passed through the first cavity 102 from the side of the through hole facing the second cavity 103, so that the baffle 72 abuts against the partition 23, and then the fixing portion can be fixed to the first end of the tubular portion 71 from the first cavity 102, so that the partition 23 is clamped between the fixing portion and the baffle 72. On the one hand, the baffle 72 plays a limiting role, fixing the position of the first valve body component 11, and on the other hand, increases the contact area between the tubular portion 71 and the periphery of the through hole, so that the through hole is better sealed, preventing water from flowing through the gap between the tubular portion 71 and the through hole, affecting the control performance of the valve body assembly 10 on the water level of the second cavity 103.

[0097] The specific structure of the fixing portion is not limited, as long as it can be fixed to the first end of the tubular portion 71. In one embodiment, as shown in Figures 10 to 12, the fixing portion is a knob 73 that is screwed to the first end. In this way, the user only needs to rotate the knob 73 to securely fix the first valve body component 11 to the partition 23. This structure is simple, reliable, and easy to operate.

[0098] To further enhance the sealing performance of the tubular portion 71 against the through-hole, a sealing ring 74 is provided on the outer surface of the tubular portion 71. The sealing ring 74 is used to cushion the space between the tubular portion 71 and the separator 23. The sealing ring 74 can be made of rubber or silicone. In one embodiment, two sealing rings 74 are provided. In this embodiment, a sleeve extending transversely from the outer periphery of the through-hole is formed on the separator 23. The tubular portion 71 is sleeved within the sleeve, thereby increasing the contact area between the tubular portion 71 and the separator 23. Furthermore, a first sealing ring 74 is provided between the inner periphery of the sleeve and the outer periphery of the tubular portion 71, while a second sealing ring 74 is provided between the baffle 72 and the separator 23. The second sealing member 81 is bent to have a portion sandwiched between the baffle 72 and the separator 23, and a portion sandwiched between the inner periphery of the sleeve and the tubular portion 71. In this way, the first sealing ring 74 and the second sealing ring 74 jointly seal the through hole, thereby enhancing the sealing performance of the first valve body component 11 on the through hole, thereby preventing water from flowing through the gap between the tubular portion 71 and the through hole and affecting the valve body assembly 10's ability to control the water level of the second chamber 103.

[0099] The above description is only a preferred embodiment of the present application and does not limit the patent scope of the present application. All equivalent structural transformations made by using the contents of the present application specification and drawings under the utility model concept of the present application, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
