Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air treatment, in particular to an air humidifying device. BACKGROUND

[0002] With the improvement of people's living standards and the increasing demand for indoor air quality, air humidifying devices have become one of the common household and office appliances. Air humidifying devices can effectively alleviate the discomfort caused by dryness, improve the breathing environment, and reduce static electricity by increasing the humidity in the air.

[0003] The existing air humidifying device usually includes a water storage tank, a water pump, a humidifying filter and a fan. The existing air humidifying device pumps the water in the water storage tank to the humidifying filter through the water pump, and blows the humidified airflow out through the fan to achieve the humidifying effect.

[0004] However, the water pump of the existing air humidifying device produces noise during operation, especially in the night or quiet environment, which will disturb the user. Moreover, the water pump is easily clogged by impurities or foreign matter in the water during long-term use, resulting in a high failure rate, increasing the maintenance and replacement costs, and affecting the user's experience. CONTENT OF THE INVENTION

[0005] In view of the above problems, the present application provides an air humidifying device which can solve the noise problem of the existing air humidifying device during operation to improve the user's experience.

[0006] The present application provides an air humidifying device, comprising: a host; a humidifying filter arranged on the upper side of the host, the humidifying filter comprising: a shell assembly defining a humidifying cavity in the shape of a ring, the shell assembly surrounding a shunt cavity located on the inner side of the humidifying cavity along the radial direction of the host, the shell assembly being provided with a shunt hole communicating the humidifying cavity and the shunt cavity; a filter body arranged in the humidifying cavity for absorbing water from the shunt hole to form a humidified airflow; a water storage tank arranged on the upper side of the shell assembly, the bottom wall of the water storage tank being provided with a water outlet communicating with the shunt cavity, the water storage tank supplying water to the shunt cavity through the water outlet, and the water outlet being openable and closable.

[0007] In this way, by placing the water storage tank on top, the air humidifying device can naturally supply water to the shunt cavity by gravity, thereby avoiding the noise problem caused by using a water pump. Moreover, the shunt cavity is located at the center of the humidifying filter, which can ensure uniform distribution of water flow. The plurality of shunt holes provided on the shell assembly allow water to flow smoothly from the shunt cavity into the humidifying cavity surrounding the outer side thereof, which can enable the humidifying filter body to absorb water more fully and form a more uniform humidified airflow.

[0008] In a possible implementation, the air humidifying device further comprises a water outlet switch, at least part of the structure of the water outlet switch is arranged in the shunt cavity and is movable along the axial direction of the main machine to open or close the water outlet.

[0009] In this way, by introducing the water outlet switch and arranging at least part of the structure of the water outlet switch in the shunt cavity and movable along the axial direction of the main machine to control the opening and closing of the water outlet, the air humidifying device can more flexibly control the water supply in the humidifying process. By moving the water outlet switch along the axial direction of the main machine, the state of the water outlet can be accurately controlled, not only the indoor humidity can be adjusted according to the actual demand, but also the problem of over-humidification caused by excessive water or poor humidifying effect caused by insufficient water can be effectively avoided.

[0010] In a possible implementation, the shell assembly further defines a float cavity, the float cavity is located on the radially inner side of the humidifying cavity and on the lower side of the shunt cavity, the bottom wall of the humidifying cavity is further provided with a communication hole, the communication hole is in communication with the float cavity; the water outlet switch comprises a float member, the float member is arranged in the float cavity in a floating and sinking manner; and a plug assembly, the plug assembly is movably arranged in the bottom wall of the shunt cavity along the axial direction of the main machine, the plug assembly is connected with the float member, and the plug assembly is adapted to move under the drive of the float member to open or close the water outlet.

[0011] In this way, the communication hole is in communication with the float cavity, the excess water in the humidifying cavity enters the float cavity through the communication hole, and then the float member is arranged in the float cavity in a floating and sinking manner. When the water in the humidifying cavity is consumed by the humidifying filter element, the water level in the float cavity decreases, and then the float member sinks, thereby triggering the water outlet switch to open the water outlet to supplement the water; on the contrary, when the water in the humidifying cavity reaches a certain degree, the float member floats up, thereby triggering the water outlet switch to close the water outlet to stop water supply. In this way, not only the water supply in the humidifying process is ensured to be stable, the problems caused by water shortage or excessive humidification are avoided, but also the user intervention is reduced, and the convenience of use is improved.

[0012] In a possible implementation, the bottom wall of the shunt cavity is provided with a through hole; the plug assembly comprises a movable rod arranged in the through hole, one end of the movable rod is connected with the float member, and a sealing member is arranged at the other end of the movable rod, the sealing member is used to open or close the water outlet.

[0013] In this way, when the water level in the float cavity changes, the change of the water level in the float cavity can be directly transmitted to the plug assembly through the float member, and then the automatic opening or closing of the water outlet can be realized, thereby improving the automation degree and reliability of the air humidifying device. Moreover, the whole process does not need to rely on an electric control system, thereby reducing the failure rate and maintenance cost.

[0014] In a possible implementation, the movable rod comprises: a first top rod arranged in the distribution cavity, the first top rod being connected with the sealing member; and a second top rod arranged through the through hole, one end of the second top rod being connected with the float member, and the other end of the second top rod being connected with the first top rod.

[0015] In this way, the compactness of the structure and the convenience of assembly can be improved. In addition, the first top rod is arranged in the distribution cavity, so that the internal space limitation can be better adapted, and the position of the sealing member when opening or closing the drain port can be ensured to be accurate. In addition, the second top rod is connected with the float member through the through hole, so that the movement conversion from the float member to the sealing member can be ensured to be more stable and accurate.

[0016] In a possible implementation, the main body comprises: a shell, the shell being provided with a partition, the partition constituting a bottom wall of the float cavity.

[0017] In this way, a stable foundation can be provided for the float cavity, and the float cavity can be effectively separated from other parts of the main body, so that the compactness and stability of the structure can be ensured.

[0018] In a possible implementation, one of the shell assembly and the partition is provided with a support protrusion facing the other, the support protrusion being used to maintain an over-flow gap between the shell assembly and the partition, the over-flow gap being used to communicate the communication hole and the float cavity.

[0019] In this way, it can be ensured that the water flow can be smoothly transmitted from the humidifying cavity to the float cavity, so that accurate response to water level change can be achieved. In addition, the over-flow gap formed by the support protrusion can make the water level change in the float cavity more stable, and the stability in the process of transmitting the buoyancy can be improved.

[0020] In a possible implementation, the partition is provided with a guide boss at a position corresponding to the float cavity, and the float member is guided and matched with the guide boss.

[0021] In this way, it can be ensured that the movement of the float member in the float cavity is more stable and accurate, and the situation that the float member deviates when the water level changes can be avoided. The guide boss provides a clear movement path for the float member, so that the float member can move up and down along the predetermined direction, and the accuracy and reliability of the response to the water level change can be improved.

[0022] In a possible implementation, the main body further comprises: a limiting member arranged through the float member and the guide boss along the axial direction of the main body, the limiting member being used to limit the float member.

[0023] Therefore, the floating member can be ensured not to move beyond the predetermined range when moving up and down, thereby avoiding control failure or mechanical damage caused by excessive movement of the floating member. The limiting member not only limits the maximum stroke of the floating member, but also further enhances the cooperation accuracy between the floating member and the guide boss, thereby ensuring that the floating member always moves along the correct path.

[0024] In a possible implementation, the shell assembly comprises: a first shell and a second shell opposite to each other in the axial direction of the main machine, the first shell and the second shell are detachably connected, and the first shell and the second shell jointly define the humidifying cavity.

[0025] Therefore, the detachable connection of the first shell and the second shell enables the user to easily separate the first shell and the second shell, thereby facilitating the cleaning and maintenance of the inside of the humidifying cavity.

[0026] In a possible implementation, the first shell comprises: a first cylinder portion, the shunt cavity is located at the radially inner side of the first cylinder portion, and the first cylinder portion is connected with the second shell; a first mounting portion is arranged at an end of the first cylinder portion away from the second shell in the axial direction of the main machine and located at the radially outer side of the first cylinder portion, and one end of the filter core body is arranged in the first mounting portion; a partition plate is arranged at the inner side of the first cylinder portion, and the partition plate and the first cylinder portion jointly define the shunt cavity with an open top, and the shunt cavity is used for containing water in the water storage tank.

[0027] Therefore, the shunt cavity with an open top enables the water in the water storage tank to flow smoothly, and the presence of the partition plate prevents the water flow from directly impacting the filter core body, thereby prolonging the service life of the filter core body. In addition, by arranging one end of the filter core body in the first mounting portion, the stable installation and positioning of the filter core body can be ensured.

[0028] In a possible implementation, the second shell comprises: a second cylinder portion, the inner side of the second cylinder portion is hollow, and the second cylinder portion is connected with the first cylinder portion; a second mounting portion is arranged at an end of the second cylinder portion away from the first shell in the axial direction of the main machine and located at the radially outer side of the second cylinder portion, and the other end of the filter core body is arranged in the second mounting portion, and the second mounting portion and the first mounting portion jointly define the humidifying cavity.

[0029] Therefore, the humidifying cavity can ensure the stability of the filter core body during the entire humidifying process. In addition, by arranging the humidifying cavity, the water can uniformly pass through the filter core body, thereby improving the humidifying efficiency and effect, and simplifying the installation and replacement process of the filter core body, thereby facilitating the user to maintain.

[0030] In a possible implementation, the host comprises: a casing provided with an air inlet; and an air flow driving device arranged in the casing and configured to drive air flow to sequentially pass through the air inlet and the humidifying filter element and then be discharged.

[0031] In this way, the relatively dry indoor air can be effectively sucked in and guided by the air flow driving device to the humidifying filter element for humidification treatment, and then the humidified air can be uniformly sent into the indoor environment. The air inlet is located at the lower side of the water storage tank, so that the air flow path is more reasonable, the air flow resistance is reduced, and the working efficiency of the air flow driving device is improved.

[0032] The air humidifying device provided by the application can supply water to the distribution cavity by gravity naturally by arranging the water storage tank above the air humidifying device, thereby avoiding the noise problem caused by using a water pump. The distribution cavity is arranged at the central position inside the humidifying filter element, so that the water flow can be uniformly distributed. The plurality of distribution holes arranged on the shell assembly allow the water to flow smoothly from the distribution cavity into the humidifying cavity around the outside of the distribution cavity, so that the humidifying filter element body can more fully absorb the water, and a more uniform humidified air flow can be formed.

[0055] Through the above-mentioned drawings, the explicit embodiments of the present application have been shown, and will be described in more detail hereinafter. These drawings and textual descriptions are not intended to limit the scope of the concept of the present application by any means, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0056] The exemplary embodiments will be described in detail herein with reference to the attached drawings. In the following description, like reference numerals refer to like elements throughout the description. The following exemplary embodiments described herein represent the best attempts at providing embodiments in conformance with the application, and are not intended to represent the only embodiments in conformance with the application. Rather, they are intended to convey examples of apparatuses and methods in conformance with some aspects of the application as detailed in the appended claims.

[0057] The existing air humidifying device usually comprises a water storage tank, a water pump, a humidifying filter element and a fan. The existing air humidifying device pumps the water in the water storage tank to the humidifying filter element through the water pump, and blows the humidified airflow out through the fan to achieve the humidifying effect. However, the existing air humidifying device produces noise when the water pump is running, especially at night or in a quiet environment, which will disturb the user. Moreover, the water pump is easily blocked by impurities or foreign matters in the water during long-term use, resulting in a high failure rate, increasing the maintenance and replacement costs, and affecting the user's experience.

[0058] Therefore, the air humidifying device is provided. The water storage tank is arranged above the humidifying filter element, so that the air humidifying device can naturally supply water to the distribution cavity by gravity, thereby avoiding the noise problem caused by the use of the water pump. The distribution cavity is located at the central position inside the humidifying filter element, ensuring uniform distribution of the water flow. The plurality of distribution holes arranged on the shell assembly allow the water to flow smoothly from the distribution cavity into the surrounding humidifying cavity, so that the humidifying filter element body can more fully absorb the water to generate more uniform humidified airflow.

[0059] It can be understood that the air humidifying device can be a mist-free humidifier, a steam humidifier, an ion humidifier or a hybrid humidifier.

[0060] When the air humidifying device is working, the air outside can enter the inside of the casing of the air humidifying device through the air inlet. The airflow driving device (such as a fan or a blower) inside the air humidifying device can drive the air to flow and pass through the humidified humidifying filter element. When the air flows through the humidified filter element, water molecules evaporate from the surface of the filter element into the airflow, thereby increasing the humidity of the air. The humidified air is discharged through the air outlet of the casing and enters the room to increase the air humidity in the room.

[0061] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of the present application will be described below with reference to the drawings:

[0062] Reference Figure 1 , Figure 2 ,Figure 3 、 Figure 6 、 Figure 7 、 Figure 8 The air humidifying device 1 can be a mist-free humidifier or other type of humidifier. The air humidifying device 1 comprises a main machine 10, a humidifying filter core 20, an airflow driving device 130 and a water storage tank 30.

[0063] The main machine 10 of the air humidifying device 1 constitutes the overall support structure thereof, and is internally provided with the airflow driving device 130, which is responsible for guiding the airflow to be discharged after sequentially passing through the air inlet 112 and the humidifying filter core 20, so as to ensure that the air can be effectively humidified by passing through the humidifying filter core 20. The airflow driving device 130 can be a fan, a blower or other similar device, and the present application does not make specific limitations thereon. In addition, the air humidifying device 1 is also provided with the water storage tank 30, which is used for supplying water to the humidifying filter core 20, so as to ensure that the humidifying filter core 20 can continuously absorb water, and further generate humid air flow. Further, the humidifying filter core 20 is located on the upper side of the main machine 10. The water storage tank 30 is located on the upper side of the humidifying filter core 20. The water storage tank 30 is provided with a water outlet 310 in communication with the humidifying filter core 20, so that the water in the water storage tank 30 can flow into the humidifying filter core 20 under the action of gravity. In addition, the water outlet 310 of the water storage tank 30 is openable and closable.

[0064] Further, the humidifying filter core 20 comprises a shell assembly 210 and a filter core body 220. The shell assembly 210 can define an annular humidifying cavity 211. The humidifying cavity 211 is used for carrying the filter core body 220. Further, the shell assembly 210 internally surrounds a shunt cavity 212. The shunt cavity 212 is located on the radially inner side of the humidifying cavity 211 along the main machine 10. The water in the water storage tank 30 can be temporarily stored in the shunt cavity 212, and the shunt cavity 212 can play a role of transition and buffering, so that the water from the water storage tank 30 can smoothly enter the humidifying cavity 211. In order to realize the communication between the humidifying cavity 211 and the shunt cavity 212, the shell assembly 210 is provided with a shunt hole 214.

[0065] Optionally, the shunt hole 214 can be located inside the shell assembly 210. For example, the shunt hole 214 can be located on the inner wall of the shunt cavity 212. The number of the shunt hole 214 can be multiple, and the multiple shunt holes 214 can be uniformly distributed along the circumference of the shunt cavity 212, so as to ensure that the water can be uniformly entered into the humidifying cavity 211. The shape of the shunt hole 214 can be circular, oval, strip-shaped or other suitable shapes, and the shape of the shunt hole 214 can be determined according to design requirements and actual requirements, and the present application does not make limitations.

[0066] Further, the filter core body 220 can be arranged in the humidifying cavity 211, and then can absorb water from the distribution hole 214 to form a humidified air flow. Optionally, the filter core body 220 can be made of synthetic fiber, fiber cotton, non-woven fabric or the like, so that the filter core body 220 has good water absorption, and then can effectively absorb water and form a humidified air flow. Moreover, the filter core body 220 made of the above-mentioned materials can be washed and dried for reuse. In addition, the filter core body 220 can also have a ring structure to adapt to the ring-shaped humidifying cavity 211 defined by the shell assembly 210.

[0067] It can be understood that, by arranging the water storage tank 30 on top, the air humidifying device 1 can naturally supply water to the distribution cavity 212 by gravity, thereby avoiding the noise problem caused by using a water pump. Moreover, the distribution cavity 212 is located at the center of the humidifying filter 20, which can ensure uniform distribution of water flow. The plurality of distribution holes 214 arranged on the shell assembly 210 allow water to flow smoothly from the distribution cavity 212 into the humidifying cavity 211 around the outside of the distribution cavity 212, so that the humidifying filter body 220 can more fully absorb water to form a more uniform humidified air flow.

[0068] In a possible implementation, referring to Figure 4 , Figure 7 , Figure 9 , the air humidifying device 1 further comprises a lower water switch 40. The lower water switch 40 is used to open and close the lower water outlet 310. At least part of the structure of the lower water switch 40 is arranged in the distribution cavity 212. For example, part of the structure of the lower water switch 40 is arranged in the distribution cavity 212. Alternatively, the entire structure of the lower water switch 40 can be arranged in the distribution cavity 212. Further, in order to change the opening and closing state of the lower water outlet 310, the lower water switch 40 can move along the axial direction of the main machine 10. For example, when the lower water switch 40 moves along the axial direction of the main machine 10 to approach the lower water outlet 310, the lower water outlet 310 is closed; when the lower water switch 40 moves along the axial direction of the main machine 10 to move away from the lower water outlet 310, the lower water outlet 310 is opened. Optionally, the lower water switch 40 can be a float type lower water switch or a spring type lower water switch.

[0069] It should be pointed out here that the air humidifying device has a first state and a second state. In the first state, the filter core body 220 is located in the humidifying cavity 211, and the lower water switch 40 is opened. In the second state, the filter core body 220 is located in the humidifying cavity 211, and the lower water switch 40 is closed.

[0070] It can be understood that by introducing the water outlet switch 40 and arranging at least part of the structure of the water outlet switch 40 in the distribution cavity 212 and movable along the axis of the main machine 10 to control the opening and closing of the water outlet 310, the air humidifying device 1 can more flexibly control the water supply in the humidifying process. By moving the water outlet switch 40 along the axis of the main machine 10 to accurately control the state of the water outlet 310, not only can the indoor humidity be adjusted according to the actual demand, but also the problem of excessive humidity caused by excessive water or poor humidifying effect caused by insufficient water can be effectively avoided.

[0071] In one possible implementation, with reference to Figure 4 、 Figure 7 、 Figure 9 , the shell assembly 210 further has a float cavity 213. The float cavity 213 is also located on the radially inner side of the humidifying cavity 211 along the main machine 10, that is, the float cavity 213 can also be defined by the shell assembly 210.

[0072] In addition, the float cavity 213 can be located on the lower side of the distribution cavity 212. In this way, part of the structure of the water outlet switch 40 can be arranged in the distribution cavity 212, and another part of the structure of the water outlet switch 40 can be arranged in the float cavity 213. In order to realize the communication between the float cavity 213 and the humidifying cavity 211, the bottom wall of the humidifying cavity 211 can be further provided with a communication hole 2111, so that the float cavity 213 can communicate with the humidifying cavity 211 through the communication hole 2111. In this way, the excess water in the humidifying cavity 211 will enter the float cavity 213 through the communication hole 2111, so that the float member 410 can be floatingly arranged in the float cavity 213. At the same time, it can also avoid excessive water in the humidifying cavity 211.

[0073] Further, the water outlet switch 40 includes a float member 410 and a plug assembly 420. The float member 410 is floatingly arranged in the float cavity 213. The float member 410 can be made of light materials with a density less than water, such as plastic or foam, so that it can float on water. The shape of the float cavity 213 can be spherical, cylindrical or a shape adapted to the cavity of the float cavity 213, which is not limited by the present application. When the water amount in the humidifying cavity 211 reaches a certain level, the excess water will flow into the float cavity 213 through the communication hole 2111, so that the float member 410 will float up. The position of the float member 410 determines the action of the plug assembly 420 connected to the float member 410.

[0074] The plug assembly 420 can be arranged in the bottom wall of the distribution cavity 212. One end of the plug assembly 420 can be connected to the float member 410 in the float cavity 213, and the other end of the plug assembly 420 can pass through the distribution cavity 212. In this way, the plug assembly 420 can be driven by the float member 410 to move along the axial direction of the main machine 10, close to or away from the water outlet 310, so as to open or close the water outlet 310. Alternatively, the plug assembly 420 can be a plug or a valve body, and correspond to the water outlet 310 of the water storage tank 30.

[0075] The plug assembly 420 can be connected to the float member 410 through a connecting mechanism. When the float member 410 floats up, the connecting mechanism drives the plug assembly 420 to move upward, thereby closing the water outlet 310; on the contrary, when the float member 410 sinks, the connecting mechanism drives the plug assembly 420 to move downward, thereby opening the water outlet 310. For example, the connecting mechanism can include one or more rigid rods. The one or more rigid rods connect the float member 410 and the plug assembly 420. Alternatively, the connecting mechanism can be a sliding link mechanism. The connecting mechanism can include a vertical guide rail and a link. The float member 410 can be connected to the plug assembly 420 through the link, and the link can slide freely in the guide rail. Alternatively, the connecting mechanism can be a magnetic coupling mechanism. The connecting mechanism can include two magnetic devices. One of the magnetic devices is located in the float member 410. The other magnetic device is located in the plug assembly 420. When the float member 410 floats up or sinks, the magnetic device inside the float member 410 will attract or repel the magnetic device in the plug assembly 420, thereby driving the plug assembly 420 to move.

[0076] It can be understood that the communication hole 2111 communicates with the float cavity 213, and the excess water in the humidification cavity 211 can enter the float cavity 213 through the communication hole 2111, so that the float member 410 is arranged in the float cavity 213 and can float and sink. When the moisture in the humidification cavity 211 is consumed by the humidification filter element 20, the water level in the float cavity 213 decreases, thereby causing the float member 410 to sink, so as to trigger the water outlet switch 40 to open the water outlet 310 to supplement the moisture; on the contrary, when the moisture in the humidification cavity 211 reaches a certain degree, the float member 410 floats up, thereby triggering the water outlet switch 40 to close the water outlet 310 to stop water supply. In this way, not only the stable water supply during humidification is ensured, the problems caused by lack of water or excessive humidification are avoided, but also the user intervention is reduced, and the convenience of use is improved.

[0077] In one possible implementation, with reference to Figure 4 、 Figure 7 、 Figure 9In order to move the plug assembly 420 in the distribution chamber 212 and the float chamber 213, the bottom wall of the distribution chamber 212 is provided with a through hole 2121. The plug assembly 420 can include a movable rod 421 and a sealing member 422. The movable rod 421 can be arranged in the through hole 2121. One end of the movable rod 421 is connected to the float member 410, and the other end of the movable rod 421 is connected to the sealing member 422. In this way, the buoyancy of the float member 410 can be transmitted to the sealing member 422 through the movable rod 421, so as to open or close the drain port 310.

[0078] Optionally, the sealing member 422 can include a main body closely fitted to the drain port 310. The main body can be made of corrosion-resistant plastic or rubber to ensure the reliability and durability of the sealing member 422 in long-term use. The upper end of the sealing member 422 can also be provided with a sealing rubber ring. The sealing rubber ring can be made of elastic material, such as silicone rubber or nitrile rubber. The sealing rubber ring can be configured to closely fit the edge of the drain port 310. When the sealing member 422 rises to close the drain port 310, the sealing rubber ring will be deformed by extrusion, forming a good sealing effect to prevent water leakage. The sealing member 422 can also be equipped with a guide structure, such as a small protrusion or a groove. The guide structure of the sealing member 422 can cooperate with the drain port 310 to help the sealing member 422 maintain the correct direction during movement and avoid deviation. Further, the drain port 310 is located at the bottom of the water storage tank 30. The drain port 310 can be a circular or other shaped opening, which is not limited in the present application.

[0079] It can be understood that when the water level in the float chamber 213 changes, the water level change in the float chamber 213 can be directly transmitted to the plug assembly 420 through the float member 410, thereby achieving automatic opening or closing of the drain port 310, and improving the automation and reliability of the air humidifying device 1. Moreover, the entire process does not need to rely on an electric control system, thereby reducing the failure rate and maintenance cost.

[0080] In a possible implementation, referring to Figure 4 、 Figure 7 、 Figure 9 The movable rod 421 includes a first top rod 4211 and a second top rod 4212. The first top rod 4211 can be located in the distribution chamber 212 and connected to the sealing member 422. The second top rod 4212 can be arranged in the through hole 2121, and one end of the second top rod 4212 is connected to the float member 410, and the other end of the second top rod 4212 is connected to the first top rod 4211. For example, the first top rod 4211 and the second top rod 4212 can be connected by threads. Alternatively, the first top rod 4211 and the second top rod 4212 can be connected by a buckle. Alternatively, the first top rod 4211 and the second top rod 4212 can be connected by a sleeve.

[0081] It can be understood that the compactness of the structure and the convenience of assembly can be improved. In addition, the first top rod 4211 is arranged in the distribution cavity 212, which can better adapt to the internal space limitation and ensure the accurate position of the sealing piece 422 when opening or closing the drain port 310. Moreover, the second top rod 4212 is connected with the float member 410 through the through hole 2121, which can ensure that the movement conversion from the float member 410 to the sealing piece 422 is more stable and accurate.

[0082] In a possible implementation, referring to Figure 1 、 Figure 2 、 Figure 6 、 Figure 8 、 Figure 9 , the host 10 comprises a casing 110. The casing 110 can protect the airflow driving device 130 inside the host 10. Moreover, the casing 110 is provided with a partition 111. The partition 111 is located on the upper side of the casing 110 to constitute the bottom wall of the float cavity 213. In this way, the partition 111 can divide the casing 110 into two parts. One part can be provided with the airflow driving device 130, and the other part bears the float cavity 213. Optionally, the partition 111 can be a flat panel, a curved panel, a special-shaped panel, etc. Further, a plurality of gratings can be arranged on the outer periphery of the partition 111 to ensure that the airflow can flow and diffuse uniformly. The gratings can be designed at a certain inclination angle to guide the airflow to flow along a specific path.

[0083] It can be understood that the float cavity 213 can be provided with a stable foundation, effectively isolating the float cavity 213 from other parts of the host 10, ensuring the compactness and stability of the structure.

[0084] In a possible implementation, referring to Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 , the shell assembly 210 is provided with a support protrusion 215. The support protrusion 215 can be arranged at the bottom of the shell assembly 210, and the support protrusion 215 can be arranged towards the partition 111. Alternatively, the partition 111 can be provided with a support protrusion 215. The support protrusion 215 can be arranged on the upper surface of the partition 111, and the support protrusion 215 can be arranged towards the shell assembly 210. The support protrusion 215 can form an overflow gap between the shell assembly 210 and the partition 111, and the overflow gap can realize the communication between the humidification cavity 211 and the float cavity 213. Optionally, the support protrusion 215 can be an annular protrusion or a plurality of cylindrical protrusions.

[0085] It can be understood that the water flow can be smoothly transmitted from the humidifying cavity 211 to the float cavity 213, so as to realize accurate response to water level change. In addition, the overflow gap formed by the support protrusion 215 can make the water level change in the float cavity 213 more stable, and improve the stability in the process of transmitting the buoyancy.

[0086] In a possible implementation, referring to Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 The guide boss 120 is arranged on the partition 111. Further, the guide boss 120 can be arranged at the bottom of the float cavity 213 and guided with the float member 410. Optionally, the float member 410 can be in a cylindrical structure, a circular table structure, a conical structure or the like. The bottom of the float member 410 can be provided with a guide groove or a recess, which can be matched with the guide boss 120, so that the float member 410 can slide along the guide boss 120.

[0087] It can be understood that the movement of the float member 410 in the float cavity 213 can be more stable and accurate, and the situation that the float member 410 deviates when the water level changes can be avoided. The guide boss 120 provides a clear movement path for the float member 410, so that the float member 410 can move up and down along the predetermined direction, thereby improving the accuracy and reliability of the response to the water level change.

[0088] In a possible implementation, referring to Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 The air humidifying device 1 further comprises a limiting member 50. The limiting member 50 can be arranged along the axial direction of the main machine 10 and penetrate the float member 410 and the guide boss 120. The limiting member 50 is used for limiting the float member 410. The limiting member 50 can be arranged on the guide boss 120 and located at the center position of the guide boss 120

[0089] Optionally, the limiting member 50 can comprise a limiting rod and a limiting head. The center of the float member 410 is provided with a recess. A through hole is arranged in the recess, and the position of the through hole corresponds to the position of the limiting member 50. The length of the limiting rod is greater than the distance between the through hole and the guide boss 120. The through hole is used for penetrating the limiting rod, and the size of the through hole is smaller than the size of the limiting head. When the float member 410 and the guide boss 120 are matched, the limiting rod can pass through the through hole, and then the limiting rod can limit the movement path of the float member 410 by cooperating with the limiting head. The limiting rod and the limiting head can be connected by plug-in, threaded connection, buckle connection or the like.

[0090] Understandably, this ensures that the float component 410 does not exceed a predetermined range when moving up and down, thereby avoiding control failure or mechanical damage caused by excessive movement of the float component 410. The limiter 50 not only limits the maximum stroke of the float component 410, but also further enhances the fit accuracy between the float component 410 and the guide boss 120, ensuring that the float component 410 always moves along the correct path.

[0091] In one possible implementation, refer to Figure 2 , Figure 4 The housing assembly 210 includes a first housing 216 and a second housing 217. The first housing 216 and the second housing 217 are detachably connected. The first housing 216 and the second housing 217 are arranged opposite each other along the axial direction of the main unit 10 to jointly define the humidification chamber 211.

[0092] Understandably, the detachable connection of the first housing 216 and the second housing 217 allows users to easily separate the first housing 216 and the second housing 217, facilitating cleaning and maintenance of the interior of the humidification chamber 211.

[0093] In one possible implementation, refer to Figure 2 , Figure 4 , Figure 6 , Figure 7 The first housing 216 includes a first cylindrical portion 2161, a first mounting portion 2162, and a partition 2163. The first cylindrical portion 2161 can be connected to the second housing 217. A diversion chamber 212 is located inside the first cylindrical portion 2161. The first mounting portion 2162 is located at one end of the first cylindrical portion 2161 and is located away from the second housing 217. The first mounting portion 2162 is used to connect to one end of the filter element body 220. A partition 2163 may also be provided inside the first cylindrical portion 2161. The partition 2163, together with the first cylindrical portion 2161, defines a top-open diversion chamber 212, through which water from the water storage tank 30 can be collected. Optionally, the center of the partition 2163 is higher than its edge, forming a frustum or quasi-frustum structure. Thus, the partition 2163 can have an inclined water-guiding slope. The water guide slope provides a clear water flow path, allowing water to flow smoothly from the center to the surroundings and eventually be evenly distributed throughout the entire distribution cavity 212, so that the humidifying filter body 220 can absorb water evenly from all directions and generate a uniform humidified airflow.

[0094] It can be understood that the open-top split-flow cavity 212 design allows water in the water storage tank 30 to flow smoothly, and the presence of the baffle 2163 prevents the water flow from directly impacting the filter core body 220, prolonging the service life of the filter core body 220. In addition, by arranging one end of the filter core body 220 at the first mounting portion 2162, the stable installation and positioning of the filter core body 220 can be ensured.

[0095] In one possible implementation, with reference to Figure 2 、 Figure 4 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 The second housing 217 includes a second cylindrical portion 2171 and a second mounting portion 2172. The inner side of the second cylindrical portion 2171 is hollow. The inside of the second cylindrical portion 2171 can form a float chamber 213. The second mounting portion 2172 can be arranged at one end of the second cylindrical portion 2171, and the second mounting portion 2172 is away from the first housing 216. The second mounting portion 2172 is located radially outward of the second cylindrical portion 2171. The second mounting portion 2172 can be connected to the other end of the filter core body 220. When the first housing 216 and the second housing 217 are connected, the second mounting portion 2172 and the first mounting portion 2162 can jointly define a humidification chamber 211.

[0096] It can be understood that the humidification chamber 211 can ensure the stability of the filter core body 220 during the entire humidification process. Moreover, by arranging the humidification chamber 211, water can be uniformly passed through the filter core body 220, thereby improving the humidification efficiency and effect, and simplifying the installation and replacement process of the filter core body 220, facilitating user maintenance.

[0097] In one possible implementation, with reference to Figure 1 、 Figure 2 、 Figure 6 、 Figure 8 、 Figure 9 The host 10 includes a casing 110 and an airflow driving device 130. The casing 110 is provided with an air inlet 112. Moreover, the airflow driving device 130 is arranged in the casing 110. In this way, the airflow driving device 130 can drive the airflow to be discharged after passing through the air inlet 112 and the humidification filter core 20 in sequence.

[0098] It can be understood that the relatively dry indoor air can be effectively sucked in and guided to the humidification filter core 20 for humidification treatment by the airflow driving device 130, and then the humidified air is uniformly sent into the indoor environment. The air inlet 112 is located at the lower side of the water storage tank 30, so that the airflow path is more reasonable, the airflow resistance is reduced, and the working efficiency of the airflow driving device 130 is improved.

[0099] In one possible design, referring to Figure 4 , Figure 6 , Figure 8 , Figure 9 , the first mounting portion 2162 is formed with an air outlet grille.

[0100] It can be understood that the design of the air outlet grille ensures uniform distribution of air flowing out of the filter core body 220, avoids poor humidification effect caused by uneven local air outlet, and improves the uniformity of humidification. The air outlet grille can also play a certain protective role to prevent fingers or other objects from directly contacting the filter core body 220, thereby improving the use safety of the equipment. In addition, the design of the air outlet grille helps to optimize the airflow path, reduce airflow resistance, and ensure smooth airflow through the filter core body 220, thereby improving the humidification effect.

[0101] In one possible design, referring to Figure 3 , the upper portion of the water storage tank 30 can be provided with a grille cover plate. The grille cover plate can be made of corrosion-resistant and easy-to-clean materials such as plastic, stainless steel, or aluminum alloy. The grille cover plate can be provided with a filter layer such as a fine mesh or an activated carbon layer to improve the filtering effect and reduce impurities in the water. The grille cover plate can be movably connected with the water storage tank 30. For example, snap connection, threaded connection, magnetic attraction connection, etc.
