Humidifiers can adjust the humidity of indoor air to meet users' needs for indoor air comfort.

[0003] In the related art, a humidifier includes a water tank assembly and a humidifier host. The water tank assembly includes a water tank and a float mechanism located in the water tank. The float mechanism includes a float bracket and a float. The float bracket is arranged in the water tank and connected to the water tank. The float bracket is surrounded by a floating space with a through hole on the top. The float is movably arranged in the floating space and partially penetrates the through hole. The float can rise and fall and move in the vertical direction as the liquid in the water tank changes to trigger or release the micro switch on the humidifier host.

[0004] However, in the related art, when the float is raised or lowered, it is easy to be displaced or get stuck with the hole wall of the through hole, resulting in poor working reliability of the whole machine. Utility Model Content

At least two rolling elements are arranged between the float and the float bracket along the circumferential interval of the floating space. The rolling element is in rolling contact with the surface of at least one of the float and the float bracket. In this way, when the float rises and falls in the floating space along the first direction as the liquid level of the water tank changes, the float and the float bracket roll relative to each other through the rolling element, thereby avoiding the problem of the float getting stuck with the float bracket when rising and falling. At the same time, at least two rolling elements can perform center positioning between the float and the float bracket to avoid the problem of the float being misaligned when rising and falling in the floating space, thereby improving the working reliability of the whole machine.

In this way, the compactness of the structure can be improved, the utilization rate of the space can be improved, and the installation and disassembly of the rolling member can be facilitated.

[0020] In some embodiments, along the axial direction of the rolling element, opposite sides of the rolling element have a rotating portion coaxial with the rolling element, and the rotating portion is rotatably connected to the float bracket.

[0021] With such arrangement, the rolling element is rotatably connected to the float bracket via the rotating portion, so that the rolling element can rotate around its own axis to prevent the float from getting stuck when it is raised or lowered.

[0022] In some embodiments, there are rotation grooves on opposite sides of the avoidance gap, and the rotating parts on opposite sides of the rolling element are respectively rotatably arranged in the rotation grooves, wherein the axis of the rotation groove is in the same straight line as the axis of the rotating part and the rolling element.

[0057] With the improvement of living standards, people have higher and higher requirements for indoor air quality and comfort, requiring not only the indoor air temperature to be within an appropriate range, but also the indoor air humidity to be within an appropriate range. A humidifier can adjust the humidity of indoor air to meet the user's demand for indoor air comfort. In the related art, a humidifier includes a water tank assembly and a humidifier host. The water tank assembly includes a water tank and a float mechanism located in the water tank. The float mechanism includes a float bracket and a float. The float bracket is arranged in the water tank and connected to the water tank. The float bracket is surrounded to form a floating space with a through hole on the top. The float is movably arranged in the floating space and partially penetrated in the through hole. The float can move up and down in the vertical direction with the change of the liquid in the water tank to trigger or release the micro switch on the humidifier host. However, in the related art, when the float rises and falls, it is easy to be offset or stuck with the hole wall of the through hole, resulting in poor working reliability of the whole machine.

[0058] In order to solve the above-mentioned problem, the present application provides a water tank assembly and a humidifier, wherein there are at least two rolling elements, and at least two rolling elements are arranged between the float and the float bracket at circumferential intervals along the floating space, and the rolling elements are in rolling contact with the surface of at least one of the float and the float bracket. In this way, when the float rises and falls in a first direction in the floating space as the liquid level in the water tank changes, the float and the float bracket roll relative to each other through the rolling elements, thereby avoiding the problem of the float getting stuck with the float bracket when rising and falling. At the same time, at least two rolling elements can perform center positioning between the float and the float bracket to avoid the problem of the float being misaligned when rising and falling in the floating space, thereby improving the working reliability of the whole machine.

[0059] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0060] The embodiment of the present application provides a humidifier, which includes but is not limited to a fogless humidifier. The fogless humidifier will be taken as an example for introduction.

[0061] Please refer to Figure 1 As shown, the humidifier 10 provided in the embodiment of the present application includes a water tank assembly 100 and a humidifier host 200 disposed on the water tank assembly 100 , and the water tank assembly 100 can provide a supporting foundation for the humidifier host 200 .

[0062] Among them, the water tank assembly 100 includes a water tank 110 and a filter element 130 arranged in the water tank 110. An air inlet can be arranged on the side wall of the water tank 110, and the air inlet can be arranged at a position close to the top of the water tank 110. In this way, it can be ensured that the water tank 110 can have a certain water holding capacity; the filter element 130 is arranged in the water tank 110 to humidify the filter element 130 through the humidification water in the water tank 110. The humidifier host 200 has an air duct connected to the water tank 110, and the humidifier host 200 also has an air outlet connected to the air duct. A fan is arranged in the air duct. When the fan is running, the air flow entering the water tank 110 through the air inlet passes through the humidification filter element 130, so that the flowing air flow carries the water molecules on the filter element 130 through the air duct and is discharged from the air outlet to increase the water molecule content of the indoor air, thereby increasing the humidity of the indoor air and achieving the purpose of humidifying the indoor air.

[0063] Among them, the humidification water contained in the water tank 110 can be pure water, or it can be an aqueous solution with additives such as mixed spices, fungicides, essential oils, etc. The embodiment of the present application does not make specific limitations on this. The liquid in the water tank 110 is generally referred to as water below and no specific explanation is given.

[0064] The water tank assembly 100 will be described in detail below with reference to the accompanying drawings.

[0065] Please refer to Figure 2 As shown, the water tank assembly 100 provided in the embodiment of the present application also includes a float mechanism 120, and the float mechanism 120 includes a float 121 and a float bracket 122. The float bracket 122 is arranged in the water tank 110 and connected to the water tank 110. For example, the float bracket 122 and the bottom wall of the water tank 110 can be connected by means of snap connection, threaded connection, magnetic attraction, etc., as long as the float bracket 122 is fixed in the water tank 110; the float bracket 122 is surrounded to form a floating space 1221, and the side wall of the float bracket 122 has a liquid inlet connected to the floating space 1221. In order to facilitate the water in the water tank to enter the floating space 1221, the float 121 is movably arranged in the floating space 1221, wherein the float 121 is made of a material with a floating function, for example, and the float 121 can float on the liquid surface of the floating space. In this way, the float 121 can rise and fall in the floating space 1221 along a first direction as the liquid level in the water tank 110 changes, and the first direction is the height direction of the water tank, so that the micro switch on the humidifier host 200 is triggered or untriggered by the rise and fall of the float 121 to change the working state of the humidifier host 200.

[0066] It is understandable that the working state of the humidifier host 200 is, for example, starting work or stopping work.

[0067] Since the float 121 floats on the liquid surface in the water tank 110, a floating space 1221 is formed by the float bracket 122. In this way, the float 121 rises and falls in a first direction in the floating space 1221. When the float 121 rises and falls in the first direction along with the change of the liquid surface, if the liquid surface in the water tank 110 fluctuates, the float 121 will also be displaced with the fluctuation of the liquid surface, resulting in direct hard contact and mutual friction between the float 121 and the float bracket 122 when the float 121 is raised and lowered, resulting in the float 121 getting stuck when it is raised and lowered, resulting in deviation in the float 121 triggering the micro switch, thereby affecting the working reliability of the whole machine.

[0068] In view of the above problems, please continue to refer to the embodiments of this application. Figure 3 and Figure 4 As shown, the float mechanism 120 also includes at least two rolling members 123, and the at least two rolling members 123 are arranged at intervals between the float bracket 122 and the float 121. The rolling member 123 can rotate around its own axis. When the float 121 rises and falls along the first direction in the floating space 1221, the rolling member 123 can roll and contact with the surface of at least one of the float bracket 122 and the float 121. In this way, when the float 121 rises and falls along the first direction in the floating space 1221 as the water level of the water tank changes, the float 121 and the float bracket 122 roll relative to each other through the rolling member 123, thereby avoiding the problem of the float 121 being stuck with the float bracket 122 when rising and falling. At the same time, at least two rolling members 123 can perform center positioning between the float 121 and the float bracket 122, so as to avoid the problem of the float 121 being offset when rising and falling in the floating space 1221, thereby improving the working reliability of the whole machine.

[0069] In some embodiments, at least two rolling members 123 can be rotatably connected to one of the float 121 and the float bracket 122, and rollingly contact the surface of the other one, so that when the float 121 rises and falls along the first direction, the float 121 and the float bracket 122 roll relative to each other through the rolling members to avoid jamming.

[0070] The rolling element 123 may be, for example, a roller or a ball with a smooth curved surface.

[0071] In some embodiments, the top of the float bracket 122 has a through hole 1222 connected to the floating space 1221, part of the structure of the float 121 is inserted into the through hole, and at least part of the structure of the rolling element 123 is located between the float 121 and the hole wall of the through hole 1222. In this way, the through hole 1222 can guide the float 121 when it rises and falls along the first direction, and the float 121 and the hole wall of the through hole 1222 are in rolling contact through the rolling element 123, so that jamming can be avoided.

[0072] That is to say, on the circumference of the through hole 1222, at least two spaced rolling elements 123 are arranged between the surface of the float 121 and the wall of the through hole 1222. When the float 121 is lifted or lowered along the extension direction of the through hole 1222, the rolling element 123 rotates around its own axis relative to the wall of the through hole 1222 and the surface of the float 121 to avoid direct contact between the float 121 and the wall of the through hole 1222, thereby preventing the float 121 from getting stuck when being lifted or lowered.

[0073] In addition, at least two rolling elements 123 can also define a lifting space for the float 121. The float 121 is located in the lifting space and rises and falls in, for example, a vertical direction. In this way, at least two rolling elements 123 can center the float 121 to prevent the float 121 from being displaced due to fluctuations in the liquid level.

[0074] In some embodiments, please refer to Figure 2 and Figure 3 As shown, the float 121 includes a float body 1211 and a trigger rod 1212 arranged on the float body 1211, the float body 1211 is movably arranged in the floating space 1221, the trigger rod 1212 is penetrated in the through hole 1222, and at least part of the structure of the rolling element 123 is arranged between the trigger rod 1212 and the hole wall of the through hole 1222; illustratively, the trigger rod 1212 is, for example, a cylindrical rod with a circular cross-section.

[0075] In the embodiment of the present application, the trigger rod 1212 and the hole wall of the through hole 1222 are in rolling contact via the rolling member 123 to avoid the problem of the trigger rod getting stuck, and the problem of the trigger rod 1212 being misaligned can also be avoided, thereby improving the smoothness of the trigger rod 1212 when it rises and falls with the float body 1211 and the accuracy and reliability of the trigger rod 1212 triggering the micro switch, thereby improving the working reliability of the entire machine.

[0076] In some embodiments, the rolling member 123 is rotatably disposed on the trigger rod 1212. For example, the rolling member 123 has an installation groove or an installation notch. The rolling member 123 is rotatably installed in the trigger rod 1212, and at least a portion of the rolling member 123 protrudes from the surface of the trigger rod 1212, and the rolling member 123 can rotate around its own axis. In this way, when the rolling member 123 is lifted or lowered along the extension direction of the through hole 1222, the trigger rod 1212 is in rolling contact with the hole wall of the through hole 1222 through the rolling member 123, so that the rolling member 123 rotates around its own axis, so as to avoid the problem of the trigger rod 1212 getting stuck when it is lifted or lowered with the float body 1211; at the same time, the problem of the trigger rod 1212 being offset can also be avoided.

[0077] In other embodiments, Figure 3 and Figure 4As shown, the rolling member 123 is rotatably disposed on the hole wall of the through hole 1222 and is in rolling contact with the surface of the trigger rod 1212; that is, the rolling member 123 is fixed on the hole wall of the through hole 1222 and can rotate around its own axis, so that when the float 121 is lifted or lowered along the first direction, the float 121 and the hole wall of the through hole 1222 roll relative to each other through the rolling member 123 to avoid jamming.

[0078] In some embodiments, please refer to Figure 3 and Figure 4 As shown, along the extension direction of the through hole 1222 , the rolling element 123 is rotatably disposed near the middle of the through hole 1222 , which can improve the accuracy of the center positioning of the float 121 by at least two rolling elements 123 .

[0079] Please continue to refer to Figures 5 to 8 As shown, the rolling member 123 is rotatably arranged on the hole wall of the through hole 1222. Exemplarily, the float bracket 122 has at least two avoidance gaps 1223 connected to the through hole 1222 along the circumference of the through hole 1222. One rolling member 123 corresponds to one avoidance gap 1223, so that at least part of the rolling member 123 is located in the through hole 1222 through the avoidance gap 1223 and is in rolling contact with the surface of the trigger rod 1212; it can be understood that the rolling member 123 is rotatably arranged on the float bracket 122, and the rolling member 123 is at least partially located in the through hole 1222 through the avoidance gap 1223, so that the hole wall of the through hole 1222 and the trigger rod 1212 are in rolling contact through the rolling member 123, thus, the compactness of the structure can be improved and the utilization rate of the space can be improved.

[0080] In some embodiments, please refer to Figure 5 , Figure 6 and Fig. 9 As shown, along the axial direction of the rolling element 123, the opposite sides of the rolling element 123 have a rotating portion 1231 coaxial with the rolling element 123, and the rotating portion 1231 is rotatably connected to the float bracket 122; it can be understood that the rolling element 123 is rotatably connected to the float bracket 122 through the rotating portion 1231, so that the rolling element 123 can rotate around its own axis to prevent the float 121 from getting stuck when it is raised or lowered.

[0081] In some embodiments, please refer to Figure 7 and Figure 8As shown, there are rotation grooves 1224 on the opposite sides of the avoidance gap 1223, and the rotating parts 1231 on the opposite sides of the rolling element 123 are respectively rotatably arranged in the rotation grooves 1224, wherein the axis of the rotation groove 1224 is in the same straight line as the axis of the rotating part 1231 and the rolling element 123. In this way, when installing the rolling element 123, it only needs to be installed from top to bottom so that the rotating part 1231 is located in the rotation groove 1224 to complete the installation of the rolling element 123. The installation is convenient and the structure is simple.

[0082] Exemplarily, the rolling element 123 is a roller, and the rotating portion 1231 is a rotating shaft coaxial with the roller (eg Fig. 9 As shown in , in this way, the rotating shaft is rotatably arranged in the rotating groove 1224 corresponding to it, the roller is located in the avoidance gap 1223, and part of the structure of the roller is located between the hole wall of the through hole 1222 and the surface of the float 121, so that when the float 121 is lifted or lowered, the roller contacts the surface of the float 121 and rotates around its own axis to prevent the problem of jamming, thereby improving the smoothness of the float 121 when it is lifted or lowered; in addition, by setting the rolling member 123 as a roller and setting the rotating part 1231 as a rotating shaft, the structure is simple, easy to implement and low in cost.

[0083] In some embodiments, the top of the avoidance gap 1223 is an open structure. In this way, when the rolling element 123 is installed, the rolling element 123 can be installed on the float bracket 122 from top to bottom through the opening structure, so that the rotating part 1231 is installed in the rotating groove 1224, and the rolling element 123 is at least partially located between the hole wall of the through hole 1222 and the trigger rod 1212 through the avoidance gap 1223, and the installation method is simple.

[0084] In some embodiments, the top of the float bracket 122 has an extension portion 1225, and the extension portion 1225 is surrounded by a through hole 1222, through which the trigger rod 1212 can be initially limited in the circumference, and then the center of the float 121 is accurately positioned by the rolling member 123, thereby improving the smoothness of the float 121 when it rises and falls and the accuracy of the movement direction.

[0085] In addition, if Figure 8 As shown in the figure, the extension portion 1225 also has a receiving groove 1226 which is circumferentially arranged on the outer peripheral side of the through hole 1222 along the circumference of the through hole 1222. It can be understood that the receiving groove 1226 is an annular groove coaxial with the through hole 1222, and at least two rolling elements 123 are partially located in the receiving groove 1226. In this way, the compactness of the structure can be improved and the utilization rate of the space can be improved.

[0086] In order to improve the connection reliability between the rolling element 123 and the extension portion 1225, in some embodiments, please continue to refer to Figure 8As shown, the groove wall of the accommodating groove 1226 has a protrusion 1227, and the protrusion 1227 is, for example, a boss arranged on the groove wall of the accommodating groove 1226, and two spaced rotation grooves 1224 are arranged on the top of the protrusion 1227, and the avoidance gap 1223 is located between the two relatively arranged rotation grooves 1224 and is connected to the rotation groove 1224. It can be understood that by arranging the rotation groove 1224 on the protrusion 1227, the connection strength between the rotating part 1231 and the rotation groove 1224 can be improved, thereby improving the rolling reliability of the rolling element 123.

[0087] In some embodiments, a recessed portion 1228 is provided at a position on the groove wall of the accommodating groove 1226 corresponding to the avoidance notch 1223, and a protruding portion 1227 is arranged on the surface of the recessed portion 1228. That is to say, the recessed portion 1228 is a structural feature formed by reducing the material of the groove wall of the accommodating groove 1226. In this way, while improving the reliability of the connection between the rotating portion 1231 and the groove wall of the accommodating groove 1226, the position of the rolling element 123 can be made closer to the surface of the float 121, so as to facilitate the rolling contact between the rolling element 123 and the surface of the float 121. In addition, the compactness of the structure can be improved, consumables can be reduced, and the utilization rate of space can be improved.

[0088] In summary, in the water tank assembly provided in the embodiment of the present application, a rolling element is designed, and there are at least two rolling elements. At least two rolling elements are arranged between the float and the float bracket along the circumferential interval of the floating space, and the rolling element is in rolling contact with the surface of at least one of the float and the float bracket. In this way, when the float rises and falls along the first direction in the floating space as the water level in the water tank changes, the float and the float bracket roll relative to each other through the rolling element, thereby avoiding the problem of the float getting stuck with the float bracket when rising and falling. At the same time, at least two rolling elements can perform center positioning between the float and the float bracket to avoid the problem of the float being misaligned when rising and falling in the floating space, thereby improving the working reliability of the whole machine.
