Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular to a humidifier. Background Art

[0002] 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 a suitable range, but also the indoor air humidity to be within a suitable range. 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 filter element located in the water tank. The humidifier host is arranged on the water tank assembly. The water tank is used to hold humidification water for the humidifier. The filter element is usually partially immersed in water to humidify the filter element. In this way, during the operation of the humidifier host, a flowing airflow is formed in the water tank. During the movement, the airflow brings out the water molecules on the filter element and discharges them through the air outlet on the humidifier host to increase the humidity in the air, thereby regulating the indoor air humidity.

[0004] However, in the related art, the filter element immersed under the water surface is ineffective because there is no relative air flow passing through it, which leads to a technical problem of low humidification efficiency. Utility Model Content

[0007] An embodiment of the present application provides a humidifier, comprising: a water tank, a filter element assembly and a humidifier host, wherein the filter element assembly is arranged in the water tank, and the humidifier host is arranged on the water tank; the filter element assembly comprises a floating part and a filter element, the floating part is movably arranged in the water tank, the filter element is arranged on the floating part and connected to the humidifier host; the filter element is constructed to be adjustable in size in a first direction; the floating part rises and falls along the first direction with the change of the liquid level in the water tank, so as to drive the filter element to expand and contract along the first direction; wherein the first direction is the height direction of the water tank.

[0008] The humidifier provided in the embodiment of the present application is designed with a floating part, and the filter element is designed to be a retractable structure along a first direction. The filter element is arranged on the floating part and connected to the humidifier host. The floating part floats on the liquid surface in the water tank and rises and falls along the first direction with the change of the liquid surface, thereby driving the filter element to retract and contract along the first direction to avoid the filter element being immersed under the water surface, so as to ensure that the filter element has a larger effective humidification area, and the end of the filter element close to the floating part can contact the water in the water tank to replenish the moisture of the filter element, thereby improving the humidification efficiency and humidification effect of the humidifier, and further improving the user experience.

[0009] In some embodiments, the filter element includes a first sub-filter element and a second sub-filter element, the first sub-filter element is disposed on the floating member, the second sub-filter element is connected to the humidifier host, and the second sub-filter element is slidingly connected to the first sub-filter element, and the first sub-filter element is configured to telescope along a first direction relative to the second sub-filter element under the drive of the floating member.

[0010] In this way, the filter element is arranged into two parts, a first sub-filter element and a second sub-filter element, the second sub-filter element is connected to the humidifier host, and the first sub-filter element is arranged on the floating part and is slidably connected to the second sub-filter element, so that the first sub-filter element can be extended and retracted along a first direction relative to the second sub-filter element, thereby ensuring that the filter element has a larger humidification area.

[0011] In some embodiments, the first sub-filter element and the second sub-filter element are both arranged to form an annular structure, and one of the first sub-filter element and the second sub-filter element is arranged on the outer circumference of the other.

[0018] With such arrangement, the first bracket drives the first sub-filter element to telescopically move relative to the second sub-filter element along the first direction, and is guided by relative sliding between the first sliding member and the second sliding member to prevent displacement or jamming.

In this way, the second sub-filter element can be prevented from being displaced circumferentially, thereby improving the accuracy and reliability of the circumferential positions of the first sub-filter element and the second sub-filter element.

[0029] In some embodiments, the second bracket has at least two first clamping parts along the circumferential direction, the humidifier host has a second clamping part matching the first clamping part, and the first clamping part is configured to be clamped with the second clamping part.

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 filter element located in the water tank, the humidifier host is arranged on the water tank assembly, the water tank is used to hold the humidification water of the humidifier, and the filter element is usually partially immersed in water to humidify the filter element; in this way, during the operation of the humidifier host, a flowing airflow is formed in the water tank, and the airflow takes out the water molecules on the filter element during the movement and discharges them through the air outlet on the humidifier host to increase the humidity in the air, thereby adjusting the indoor air humidity. However, in the related art, the filter element immersed below the water surface is invalid because there is no relative air flow passing through, resulting in a technical problem of low humidification efficiency.

[0057] In order to solve the above problems, the present application provides a humidifier, by designing a floating part, and designing the filter element as a structure that can be retracted along a first direction, the filter element is arranged on the floating part and connected to the humidifier host, the floating part floats on the liquid surface in the water tank, and rises and falls along the first direction with the change of the liquid surface, thereby driving the filter element to retract and retract along the first direction to avoid the filter element being immersed under the water surface, so as to ensure that the filter element has a larger effective humidification area, and the end of the filter element close to the floating part can contact the water in the water tank to replenish the moisture of the filter element, thereby improving the humidification efficiency and humidification effect of the humidifier, and further enhancing the user experience.

[0058] 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.

[0059] An embodiment of the present application provides a humidifier, which includes but is not limited to a fogless humidifier. The humidifier will be introduced below by taking the fogless humidifier as an example.

[0060] Please refer to Figure 1 As shown, the humidifier 10 provided in the embodiment of the present application includes a water tank 100, a filter element assembly 200 and a humidifier host 300, the filter element assembly 200 is arranged in the water tank 100, and the humidifier host 300 is arranged on the water tank 100, that is, the water tank 100 provides a supporting base for the humidifier 10, and the water tank 100 is used to hold humidification water for the humidifier 10.

[0061] In some embodiments, an air inlet may be provided on the side wall of the water tank 100, and the air inlet may be provided at a position near the top of the water tank 100, so that the water tank 100 can have a certain water holding capacity; the filter element assembly 200 includes a filter element 220, and the filter element 220 is provided in the water tank 100 to humidify the filter element 220 with the humidification water of the water tank, and the humidifier host 300 has an air duct connected to the water tank 100, and the humidifier host 300 also has an air outlet connected to the air duct, and a fan is provided in the air duct. When the fan is running, the air flow entering the water tank 100 through the air inlet passes through the filter element 220, so that the water molecules on the filter element 220 are carried by the flowing air flow through the air duct and discharged from the air outlet, so as 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.

[0062] In order to improve the humidification efficiency of the humidifier 10 and increase the humidification area of ​​the filter element 220, in the embodiment of the present application, please refer to Figures 2 to 4 As shown, the filter element assembly 200 includes a floating member 210 and a filter element 220, the floating member 210 is movably arranged in the water tank 100, the filter element 220 is arranged on the floating member 210 and is connected to the humidifier host 300; the filter element 220 is constructed to be adjustable in size in a first direction; the floating member 210 rises and falls along the first direction with the change of the liquid level in the water tank 100, so as to drive the filter element 220 to expand and contract along the first direction; wherein the first direction is the height direction of the water tank 100.

[0063] The floating member 210 is, for example, a floating bottle or other structure made of a material that can float on the liquid surface. By setting the floating member 210, and setting the filter element 220 on the floating member 210 and fixedly connected to the floating member 210, the floating member 210 and the filter element 220 on the floating member 210 float on the liquid surface. In addition, the floating member 210 drives the filter element 220 to rise and fall along a first direction as the liquid surface changes. The first direction is, for example, Figure 3 and Figure 4 The direction of the arrow.

[0064] In addition, by setting the filter element 220 as a structure that can be retracted along the first direction, the filter element 220 is set on the floating member 210 and the top of the filter element 220 is fixedly connected to the humidifier host 300, and the bottom of the filter element 220 is connected to the floating member 210. When the floating member 210 rises and falls along the first direction with the change of the liquid level, the filter element 220 retracts and contracts in the first direction relative to the humidifier host 300, so that the bottom of the filter element 220 is always in contact with the liquid surface in the water tank 100, so as to provide moisture to the top of the filter element 220 through the bottom of the filter element 220, so that the filter element 220 as a whole remains in a humidified state.

[0065] Since the filter element 220 is arranged on the floating member 210 and floats on the liquid surface, there is no filter element 220 immersed under the water surface, thereby increasing the area of ​​the filter element 220 exposed above the liquid surface. When the air flow flows through the filter element 220, the contact area between the air flow and the filter element 220 is increased, so that the water molecules on the filter element 220 can be carried by the air flow and discharged into the indoor air through the air outlet, thereby increasing the efficiency of humidifying the indoor air.

[0066] It can be seen that the humidifier 10 provided in the embodiment of the present application is designed with a floating part 210, and the filter element 220 is designed as a structure that can be retracted along the first direction. The filter element 220 is arranged on the floating part 210 and connected to the humidifier host 300. The floating part 210 floats on the liquid surface in the water tank 100, and rises and falls along the first direction with the change of the liquid surface, thereby driving the filter element 220 to retract and retract along the first direction to avoid the filter element 220 being immersed under the water surface, so as to ensure that the filter element 220 has a larger effective humidification area, and the end of the filter element 220 close to the floating part 210 can contact the water in the water tank 100 to replenish the moisture of the filter element 220, thereby ensuring the stability of the humidification amount of the whole machine, and improving the humidification efficiency and humidification effect of the humidifier 10, thereby improving the user experience.

[0067] In some embodiments, please refer to Figures 2 to 4As shown, the filter element 220 includes a first sub-filter element 221 and a second sub-filter element 222. The first sub-filter element 221 is arranged on the floating member 210 and connected to the floating member 210, the second sub-filter element 222 is connected to the humidifier host 300, and the second sub-filter element 222 is slidingly connected to the first sub-filter element 221. The first sub-filter element 221 is configured to telescope relative to the second sub-filter element 222 along a first direction under the drive of the floating member 210.

[0068] In the embodiment of the present application, the filter element 220 is configured to consist of a first sub-filter element 221 and a second sub-filter element 222, so that the second sub-filter element 222 is connected to the humidifier host 300. The first sub-filter element 221 is configured on the floating member 210 and is slidably connected to the second sub-filter element 222, so that the first sub-filter element 221 can slide and retract relative to the second sub-filter element 222 along a first direction to ensure that the filter element 220 has a larger humidification area. For example, when the liquid level in the water tank 100 drops, the floating member 210 drives the first sub-filter element 221 to drop along the first direction, thereby increasing the humidification area of ​​the filter element 220 and improving the humidification efficiency of the humidifier 10.

[0069] In some embodiments, the first sub-filter element 221 and the second sub-filter element 222 are both arranged to form an annular structure, and one of the first sub-filter element 221 and the second sub-filter element 222 is arranged on the outer circumference of the other. Figures 2 to 4 In the figure, the first sub-filter element 221 is arranged around the outer peripheral side of the second sub-filter element 222, and the first sub-filter element 221 and the second sub-filter element 222 are slidably connected, that is, the first sub-filter element 221 is sleeved on the outer peripheral side of the second sub-filter element 222, and the second sub-filter element 222 is slidably connected.

[0070] It can be understood that by configuring the first sub-filter element 221 and the second sub-filter element 222 to be annular structures, the area of ​​the filter element 220 can be increased, thereby increasing the effective humidification area of ​​the filter element 220 and improving the humidification efficiency of the humidifier 10.

[0071] In some embodiments, the filter element assembly 200 further includes a first guide member (not shown in the figure) and a second guide member (not shown in the figure) matching the first guide member; the first guide member is connected to the side wall of the first sub-filter element 221 and extends along the first direction; the second guide member is connected to the side wall of the second sub-filter element 222 and extends along the first direction, and the first guide member is slidably connected to the second guide member. Exemplarily, the first guide member is, for example, one of a guide groove and a guide rail, and the second guide member is, for example, the other of the guide groove and the guide rail, and the guide is located in the guide groove and moves along the extension direction of the guide groove under the action of force.

[0072] It can be seen that by providing the first guide member and the second guide member, the telescopic movement of the first sub-filter element 221 relative to the second sub-filter element 222 along the first direction is guided to avoid the phenomenon of offset and jamming, thereby improving the smoothness of the relative movement between the first sub-filter element 221 and the second sub-filter element 222.

[0073] In addition, please continue to refer to Figures 2 to 4 As shown, the filter element assembly 200 also includes a first bracket 230 and a second bracket 240. The first bracket 230 and the second bracket 240 are arranged relatively to each other in the water tank 100 along a first direction. Along the first direction, the first bracket 230 is connected between the floating member 210 and the first sub-filter element 221. Exemplarily, the first bracket 230 is fixedly connected to the floating member 210, and the first sub-filter element 221 is fixed on the first bracket 230; the second bracket 240 is connected between the second sub-filter element 222 and the humidifier host 300. Exemplarily, the second bracket 240 is fixedly connected to the humidifier host 300, and the second sub-filter element 222 is fixed on the second bracket 240, wherein the first bracket 230 and the second bracket 240 are arranged relatively to each other, that is, the first bracket 230 is used to install the side of the first sub-filter element 221 facing the second bracket 240, and the second bracket 240 is used to install the side of the second sub-filter element 222 facing the first bracket 230.

[0074] In an embodiment of the present application, the first sub-filter element 221 is fixedly connected to the floating member 210 via the first bracket 230, and the second sub-filter element 222 is fixedly connected to the humidifier host 300 via the second bracket 240, so as to improve the reliability of the connection between the first sub-filter element 221 and the second sub-filter element 222 and the floating member 210 and the humidifier host 300 respectively.

[0075] Exemplarily, the first bracket 230 and the floating member 210 are detachably connected, for example, by means of threaded connection, snap connection, magnetic attraction, etc.; the second bracket 240 can also be detachably connected by means of threaded connection, snap connection or magnetic attraction; in order to facilitate the maintenance and care of the filter element assembly 200 or the replacement of parts in the filter element assembly 200, etc., the specific adaptive design can be carried out according to actual needs and is not limited here.

[0076] For example, Figure 5 As shown in the figure, the second bracket 240 is provided with a first clamping portion 2413, and the humidifier host 300 is provided with a second clamping portion matching the first clamping portion 2413. When the second bracket 240 is connected to the humidifier host 300, the first clamping portion 2413 is clamped with the second clamping portion; wherein the first clamping portion 2413 is, for example, a clamping convexity, and the second clamping portion is, for example, a clamping platform or a clamping groove, etc., as long as the two can be clamped; in addition, the first bracket 230 is, for example, threadedly connected to the floating member 210 through a threaded connector, thereby fixing the first bracket 230 with the floating member 210.

[0077] It is understandable that by detachably connecting the second bracket 240 to the humidifier host 300 , it is convenient to replace, clean or maintain the filter element 220 .

[0078] In addition, the first sub-filter element 221 and the first bracket 230 can be connected by gluing and bonding; the second sub-filter element 222 and the second bracket 240 can also be connected by gluing and bonding to improve the fixing reliability between the first bracket 230 and the first sub-filter element 221, and to improve the fixing reliability between the second bracket 240 and the second sub-filter element 222.

[0079] In order to further improve the reliability of the telescopic movement between the first sub-filter element 221 and the second sub-filter element 222, in the embodiment of the present application, please refer to Figures 2 to 6 As shown in the figure, the side of the first bracket 230 facing the second bracket 240 has at least one first sliding member 231 extending along the first direction, and the side of the second bracket 240 facing the first bracket 230 has a second sliding member 241 matching the first sliding member 231, and the first sliding member 231 is slidably connected to the second sliding member 241; in this way, the first bracket 230 drives the first sub-filter element 221 to telescopically move relative to the second sub-filter element 222 along the first direction, and is guided by the relative sliding between the first sliding member 231 and the second sliding member 241 to prevent displacement or jamming.

[0080] In some embodiments, Figure 6 As shown in the figure, the first sliding member 231 and the second sliding member 241 are both sliding rods, for example, one of the two sliding rods has a sliding groove 2313 that matches the other, the sliding rod is located in the sliding groove 2313 and slides along the sliding groove 2313 under the action of force. It can be understood that the sliding connection between the sliding rod and the sliding groove 2313 has a simple structure, is easy to implement, and has low cost.

[0081] It should be noted that, in the embodiment of the present application, only the first guide member may be provided on the first sub-filter element 221, and the second guide member may be provided on the second sub-filter element 222, so that the relative movement between the first sub-filter element 221 and the second sub-filter element 222 is guided by the first guide member and the second guide member, and the first sliding member 231 and the second sliding member 241 are not provided on the first bracket 230 and the second bracket 240, respectively; or, only the first sliding member 231 extending toward the second bracket 240 may be provided on the first bracket 230, and the second sliding member 241 extending toward the first bracket 230 may be provided on the second bracket 240, when When the first sub-filter element 221 and the second sub-filter element 222 move relative to each other, the first sliding member 231 and the second sliding member 241 guide the direction of movement, that is, the first guide member and the second guide member are not provided on the first sub-filter element 221 and the second sub-filter element 222 respectively; or, the first guide member and the second guide member are provided on the first sub-filter element 221 and the second sub-filter element 222 at the same time, and the first sliding member 231 and the second sliding member 241 are provided on the first bracket 230 and the second bracket 240 respectively. As long as the relative movement between the first sub-filter element 221 and the second sub-filter element 222 can be guided, there is no limitation here.

[0082] In order to prevent the first sub-filter element 221 and the second sub-filter element 222 from slipping off each other during relative movement, in some embodiments, please refer to Figure 6 As shown, a limiting protrusion 2412 is provided on at least one of the first sliding member 231 and the second sliding member 241, and a limiting groove 2311 extending along the first direction is provided on the other of the first sliding member 231 and the second sliding member 241. When the first sliding member 231 and the second sliding member 241 slide relative to each other to the extreme position at the end, the limiting protrusion 2412 abuts against the groove wall of the limiting groove 2311 to limit the movement of the first sub-filter element 221 in the first direction. It can be understood that by providing the limiting protrusion 2412 and the limiting groove 2311, the problem of mutual separation of the first sliding member 231 and the second sliding member 241 when sliding to the extreme positions at both ends is prevented, thereby improving the reliability of relative sliding between the first sliding member 231 and the second sliding member 241.

[0083] For example, in Figure 6In the embodiment, a limiting groove 2311 is provided on the first sliding member 231, and a limiting protrusion 2412 is provided at one end of the second sliding member 241 close to the first bracket 230. The limiting protrusion 2412 is provided in the limiting groove 2311. When the first sub-filter element 221 slides along the first direction relative to the second sub-filter element 222, the limiting protrusion 2412 slides along the limiting groove 2311. When the first sub-filter element 221 drops to the maximum limit position along the first direction relative to the second sub-filter element 222, the limiting protrusion 2412 abuts against the groove wall of the limiting groove 2311 to limit the limiting protrusion 2412 so as to limit the movement of the first sub-filter element 221 in the first direction and prevent the first sub-filter element 221 and the second sub-filter element 222 from detaching from each other. In this way, the reliability of the sliding connection between the first sub-filter element 221 and the second sub-filter element 222 is improved.

[0084] Of course, when there is no first sliding member 231 and the second sliding member 241, the limiting protrusion 2412 and the limiting groove 2311 can be respectively set on the first guide member and the second guide member. The principle is the same as that of setting on the first sliding member 231 and the second sliding member 241, and will not be repeated here.

[0085] In some embodiments, please refer to Figure 3 and Figure 4 As shown, the first sub-filter element 221 is arranged around the outer peripheral side of the second sub-filter element 222, and the first sliding member 231 and the second sliding member 241 are located between the first sub-filter element 221 and the second sub-filter element 222. That is to say, when the first sub-filter element 221 and the second sub-filter element 222 are sleeved, the first sliding member 231 is arranged on the inner wall of the first sub-filter element 221, and the second sliding member 241 is arranged on the outer wall of the second sub-filter element 222. It can be understood that by arranging the first sliding member 231 and the second sliding member 241 between the first sub-filter element 221 and the second sub-filter element 222, the structural compactness of the filter element assembly 200 can be improved, the space rate can be improved, and the volume of the whole machine can be reduced.

[0086] In order to further improve the compactness of the filter element assembly 200, please refer to Figure 2 As shown in the figure, the outer wall surface of the second sub-filter element 222 has an avoidance groove 2221 extending along the first direction, and the second sliding member 241 is located in the avoidance groove 2221. In this way, by setting the avoidance groove 2221 on the outer wall surface of the second sub-filter element 222, the second sliding member 241 is set in the avoidance groove 2221, so as to further improve the compactness of the structure and improve the space utilization.

[0087] In some embodiments, please refer to Figure 2 and Figure 6As shown, the first bracket 230 is provided with a first mounting groove 2312, and the first sub-filter element 221 is provided in the first mounting groove 2312; the second bracket 240 is provided with a second mounting groove (not shown in the figure), and the second sub-filter element 222 is provided in the second mounting groove. In the embodiment of the present application, by providing the first mounting groove 2312 on the first bracket 230 and providing the first sub-filter element 221 in the first mounting groove 2312, the first sub-filter element 221 can be prevented from being displaced in the circumferential direction of the first bracket 230; similarly, by providing the second mounting groove on the second bracket 240, the second sub-filter element 222 is provided in the second mounting groove, and the second sub-filter element 222 can be prevented from being displaced in the circumferential direction, thereby improving the accuracy and reliability of the circumferential positions of the first sub-filter element 221 and the second sub-filter element 222.

[0088] In some embodiments, please refer to Figure 2 and Figure 3 As shown, the humidifier 10 also includes a float 400 and a float bracket 500, the filter element assembly 200 is surrounded to form a hollow structure 250, wherein the hollow structure 250 passes through the floating member 210, the first bracket 230, the first sub-filter element 221, the second sub-filter element 222 and the second bracket 240 at one time, the float bracket 500 is arranged in the hollow structure 250 and connected to the water tank 100, the float bracket 500 is surrounded to form a floating space 510 with an opening at the top, the float 400 has a trigger part 410, the float 400 is arranged in the floating space 510, and the trigger part 410 is penetrated in the opening, the float 400 is configured to rise and fall in the floating space 510 along the first direction with the change of the liquid level in the water tank 100, so as to drive the trigger part 410 to trigger or release the micro switch on the humidifier host 300, so as to change the working state of the humidifier host 300.

[0089] In the embodiment of the present application, by disposing the float 400 and the float bracket 500 in the hollow structure 250 of the filter element assembly 200, the structural compactness of the humidifier 10 is improved and the space utilization is improved.

[0090] It can be understood that the float 400 is, for example, a structure such as a float bottle made of a material having a floating function, so that the float 400 floats on the liquid surface and rises and falls in a first direction as the liquid level changes, so that the trigger part 410 contacts or releases contact with the micro switch on the humidifier host 300 to change the working state of the humidifier host 300.

[0091] The humidifier provided in the embodiment of the present application is designed with a floating part, and the filter element is designed to be a retractable structure along a first direction. The filter element is arranged on the floating part and connected to the humidifier host. The floating part floats on the liquid surface in the water tank and rises and falls along the first direction with the change of the liquid surface, thereby driving the filter element to retract and contract along the first direction to avoid the filter element being immersed under the water surface, so as to ensure that the filter element has a larger effective humidification area, and the end of the filter element close to the floating part can contact the water in the water tank to replenish the moisture of the filter element, thereby improving the humidification efficiency and humidification effect of the humidifier, and further improving the user experience.
