Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a water tank assembly and a humidifier. Background Art

[0002] As people's living standards improve, they demand increasingly higher levels of indoor air 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. Humidifiers are widely used because they can regulate indoor air humidity. In related art, a humidifier includes a base assembly and a water tank assembly, which is mounted on the base assembly. Currently, when adding water to the water tank assembly, users typically visually determine whether it is full. This can easily lead to water overflowing the tank due to not noticing the water level or improper operation. Utility Model Content

[0003] The utility model aims to solve one of the technical problems in the related art at least to a certain extent.

[0004] To this end, the present invention proposes a water tank assembly, which can prevent water in the water tank from overflowing the water tank.

[0005] The water tank assembly of the utility model includes a water tank and a float, wherein the water tank is provided with a water inlet; the float is movably arranged in the water tank along the height direction of the water tank, and the float has a blocking portion, which blocks the water inlet when the water level in the water tank is equal to or greater than a first preset value.

[0006] When the user adds water to the water tank through the water inlet, the float moves upward as the water level in the water tank rises. When the water level in the water tank reaches a first preset value, the blocking portion of the float blocks the water inlet in the water tank, preventing the user from adding water further, thereby preventing the water in the water tank from overflowing.

[0007] In some optional embodiments, the water tank assembly includes a mounting bracket installed within and connected to the water tank, and the float is movably connected to the mounting bracket along the height of the water tank. By installing the mounting bracket within the water tank and connecting the float to the mounting bracket, the mounting bracket can be used to limit the float's position, allowing it to move along a predetermined path. When the water level within the water tank is equal to or greater than a first preset value, the blocking portion of the float blocks the water inlet. This improves the reliability of the water tank assembly.

[0008] In some optional embodiments, the mounting bracket is rod-shaped, and the float is mounted on the outside of the mounting bracket. By configuring the mounting bracket as a rod and mounting the float on the outside of the mounting bracket, assembly of the float and the mounting bracket is facilitated, thereby improving assembly efficiency of the water tank assembly and reducing the cost of the water tank assembly.

[0009] In some optional embodiments, the float is annular. By configuring the float as an annular shape, the buoyancy force on the float is also annular, thereby preventing uneven force on the float in the circumference of the mounting frame, thereby preventing the float from tilting. When the water level in the water tank is equal to or greater than a first preset value, the blocking portion of the float blocks the water inlet, further improving the reliability of the water tank assembly.

[0010] In some optional embodiments, the water tank assembly includes a mist guide tube, which is disposed within and connected to the water tank, and the mist guide tube forms the mounting bracket. By using the mist guide tube as the mounting bracket, the structure of the water tank assembly can be simplified and the cost of the water tank assembly can be reduced.

[0011] In some optional embodiments, the mounting bracket is provided with a first limiting portion, and the float is provided with a plurality of second limiting portions spaced apart along the height direction of the water tank. The first limiting portion is provided between two adjacent second limiting portions and is movable relative to the second limiting portions along the height direction of the water tank. The first limiting portion abuts against one of the second limiting portions when the water level in the water tank is less than or equal to a second preset value, and the first limiting portion abuts against another second limiting portion when the water level in the water tank is greater than or equal to a third preset value. The third preset value is greater than the second preset value and greater than or equal to the first preset value, and the second preset value is less than the first preset value. By providing the first limiting portion on the mounting bracket and the second limiting portion on the float, the range of movement of the float in the vertical direction can be limited, preventing the float from falling off the mounting bracket, and further improving the reliability of the water tank assembly.

[0012] In some optional embodiments, the mounting bracket is provided with a limiting protrusion, and the float is provided with a limiting groove. The limiting protrusion is disposed within the limiting groove and is movable relative to the limiting groove along the height direction of the water tank. The limiting protrusion forms the first limiting portion, and the sidewalls of the limiting groove, which are arranged opposite to each other along the height direction of the water tank, form the second limiting portion. By forming the limiting protrusion as the first limiting portion and the sidewalls of the limiting groove, which are arranged opposite to each other along the height direction of the water tank, forming the second limiting portion, the structures of the mounting bracket and the float can be simplified, which helps reduce the cost of the water tank assembly.

[0013] In some optional embodiments, the float is a hollow structure. By setting the float as a hollow structure, the density of the float can be reduced, making it easier for the float to float on the water surface of the water tank.

[0014] In some optional embodiments, the water tank includes a body and a top cover, the top cover being connected to the body, the water inlet being disposed on the top cover, the float being disposed corresponding to the water inlet, and the blocking portion abutting against the top cover when the water level within the water tank is equal to or greater than a first preset value. By disposing the water inlet on the top cover, the float can stably abut against the top cover under the action of an upward buoyancy force, thereby reliably blocking the water inlet, thereby improving the reliability of the water tank assembly.

[0015] The top cover is provided with a recessed portion, and the water inlet is disposed in the recessed portion. When adding water to the water tank, water can be poured into the recessed portion, allowing water to flow from the water inlet into the water tank, thus facilitating water filling. Furthermore, when the water level in the water tank reaches a first preset value, continued water addition through the water inlet will cause the water to be stored in the recessed portion, preventing it from flowing out, thereby improving the user experience. Furthermore, by lifting the top cover, the water stored in the recessed portion can flow into the water tank through the water inlet.

[0016] The humidifier of the present invention comprises a base assembly and a water tank assembly, wherein the water tank assembly is any one of the water tank assemblies described above and is arranged on the base assembly, thereby improving the user experience of the humidifier.

[0034] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0035] Reference below Figures 1 to 7 The water tank assembly 10 according to an embodiment of the present invention is introduced.

[0036] like Figures 1 to 7 As shown, the water tank assembly 10 of the present invention includes a water tank 1 and a float 2. The float 2 is movably disposed in the water tank 1 along the height direction of the water tank 1. The water tank 1 is provided with a water inlet 121. The float 2 has a blocking portion 21. The blocking portion 21 blocks the water inlet 121 when the water level in the water tank 1 is equal to or greater than a first preset value.

[0037] When the water tank 1 is nearly full of water or is full of water, the water level in the water tank 1 is a first preset value.

[0038] In the water tank assembly 10 of the present invention, when the user adds water to the water tank 1 through the water inlet 121, the float 2 moves upward as the water level in the water tank 1 rises. When the water level in the water tank 1 is equal to or greater than a first preset value, the blocking portion 21 of the float 2 blocks the water inlet 121 of the water tank 1, preventing the user from adding water to the water tank 1, thereby preventing the water in the water tank 1 from overflowing from the water tank 1. Figures 1 to 5 shown.

[0039] In some embodiments, as Figures 1 to 5As shown, the water tank assembly 10 includes a mounting frame 3 , which is disposed in and connected to the water tank 1 , and a float 2 is movably connected to the mounting frame 3 along a height direction of the water tank 1 .

[0040] By providing a mounting bracket 3 within the water tank 1 and connecting the float 2 to the mounting bracket 3, the mounting bracket 3 can be used to limit the position of the float 2, causing the float 2 to move along a set path. When the water level within the water tank 1 is equal to or greater than a first preset value, the blocking portion 21 of the float 2 blocks the water inlet 121. This improves the reliability of the water tank assembly 10.

[0041] Alternatively, as Figures 1 to 4 As shown, the mounting frame 3 is in the shape of a rod extending along the height direction of the water tank 1 , and the float 2 is sleeved on the outer side of the mounting frame 3 .

[0042] By setting the mounting frame 3 to be rod-shaped and sleeved on the outside of the mounting frame 3, the assembly between the float 2 and the mounting frame 3 is facilitated, which is beneficial to improving the assembly efficiency of the water tank assembly 10 and reducing the cost of the water tank assembly 10.

[0043] Alternatively, as Figure 5 and Figure 6 As shown, the float 2 is annular.

[0044] For example, the float 2 is in a ring shape, and the float 2 forms an insertion hole 23 . The float 2 is sleeved on the mounting frame 3 through the insertion hole 23 .

[0045] By setting the float 2 in a ring shape, the buoyancy on the float 2 is also ring-shaped, avoiding uneven force on the float 2 in the circumferential direction of the mounting frame 3, thereby preventing the float 2 from tilting. When the water level in the water tank 1 is equal to or greater than the first preset value, the sealing portion 21 of the float 2 blocks the water inlet 121, further improving the reliability of the water tank assembly 10.

[0046] Of course, in other embodiments, the float 2 may also be configured as a three-quarter ring.

[0047] Alternatively, as Figure 1 and Figure 3 As shown, the water tank assembly 10 includes a mist guide pipe, which is arranged in the water tank 1 and connected to the water tank 1, and the mist guide pipe forms a mounting frame 3.

[0048] By using the mist guide tube as the mounting bracket 3 , the structure of the water tank assembly 10 can be simplified and the cost of the water tank assembly 10 can be reduced.

[0049] In some embodiments, the mounting frame 3 is provided with a first stopper 31, and the float 2 is provided with a plurality of second stoppers 22 spaced apart along the height direction of the water tank 1. The first stopper 31 is provided between two adjacent second stoppers 22 and is movable relative to the second stoppers 22 along the height direction of the water tank 1. The first stopper 31 abuts against one of the second stoppers 22 when the water level in the water tank 1 is less than or equal to a second preset value. The first stopper 31 abuts against another second stopper 22 when the water level in the water tank 1 is greater than or equal to a third preset value. The third preset value is greater than the second preset value, which is greater than or equal to the first preset value, and the first preset value is greater than the second preset value.

[0050] For example, Figure 2 and Figure 4 As shown, the third preset value is greater than the second preset value, the third preset value is greater than the first preset value, and the first preset value is greater than the second preset value. The float 2 is provided with two second limit portions 22 spaced apart along the height direction of the water tank 1, wherein one first limit portion 31 is provided above the other first limit portion 31. The first limit portion 31 is provided between the two second limit portions 22 in the vertical direction. Figure 1 and Figure 2 As shown, when the water level in the water tank 1 is equal to the second preset value, the float 2 is in the first position, and the first limiting portion 31 stops at the second limiting portion 22 located on the lower side; when the water level in the water tank 1 is equal to the first preset value, the float 2 is in the second position, and the blocking portion 21 blocks the water inlet 121 of the water tank 1; when the water level in the water tank 1 is equal to the third preset value, the float 2 is in the third position, and the first limiting portion 31 stops at the second limiting portion 22 located on the upper side.

[0051] By providing a first limit portion 31 on the mounting frame 3 and a second limit portion 22 on the float 2, the upward and downward movement range of the float 2 can be limited, thereby preventing the float 2 from escaping from the mounting frame 3 and further improving the reliability of the water tank assembly 10.

[0052] Alternatively, as Figure 2 and Figure 4 As shown, the mounting bracket 3 is provided with a limiting protrusion, and the float 2 is provided with a limiting groove. The limiting protrusion is disposed within the limiting groove and is movable relative to the limiting groove along the height direction of the water tank 1. The limiting protrusion forms a first limiting portion 31, and the side walls of the limiting groove arranged opposite to each other along the height direction of the water tank 1 form a second limiting portion 22.

[0053] For example, the mounting frame 3 is provided with an annular limiting protrusion, the float 2 is provided with an annular limiting groove, and the notch of the limiting groove faces the limiting protrusion. Figure 1 and Figure 2As shown, when the water level in the water tank 1 is equal to the second preset value, the float 2 is in the first position, and the first limiting portion 31 stops at the lower side wall of the limiting groove; when the water level in the water tank 1 is equal to the third preset value, the float 2 is in the third position, and the first limiting portion 31 stops at the upper side wall of the limiting groove.

[0054] By forming the first limiting portion 31 with the limiting protrusion and forming the second limiting portion 22 with the side walls of the limiting groove arranged relatively along the height direction of the water tank 1, the structure of the mounting frame 3 and the float 2 can be simplified, which is beneficial to reducing the cost of the water tank assembly 10.

[0055] In other embodiments, the mounting frame 3 is provided with a plurality of first stoppers 31 spaced apart along the height direction of the water tank 1, and the float 2 is provided with a first stopper, which is disposed between two adjacent second stoppers and is movable relative to the second stoppers along the height direction of the water tank 1. The first stopper abuts against one of the second stoppers when the water level in the water tank 1 is less than or equal to a second preset value, and abuts against another second stopper when the water level in the water tank 1 is greater than or equal to a third preset value. The third preset value is greater than the second preset value, which is greater than or equal to the first preset value, and the first preset value is greater than the second preset value.

[0056] Alternatively, as Figure 2 and Figure 4 As shown, the float 2 is a hollow structure.

[0057] For example, Figure 2 and Figure 4 As shown, the float 2 has an annular cavity which is arranged around the mounting frame 3 .

[0058] By setting the float 2 as a hollow structure, the density of the float 2 can be reduced, making it easier for the float 2 to float on the water surface of the water tank 1.

[0059] Alternatively, as Figure 1 、 Figure 3 and Figure 5 As shown, the water tank 1 includes a tank body 11 and a top cover 12. The top cover 12 is disposed on the top of the tank body 11 and connected to the tank body 11. A water inlet 121 is disposed on the top cover 12, and the float 2 is disposed corresponding to the water inlet 121. The blocking portion 21 abuts against the top cover 12 when the water level in the water tank 1 is equal to or greater than a first preset value.

[0060] The top cover 12 and the box body 11 can be snap-fitted or connected via fasteners, which can be bolts, screws, rivets, etc.

[0061] For example, Figure 2 、 Figure 4 and Figure 6As shown, the top cover 12 is arranged on the upper part of the box body 11, and the top cover 12 has a downward-facing stop surface 123. When the water level in the water tank 1 is equal to or greater than a first preset value, the upper surface of the float 2 stops at the stop surface 123 of the top cover 12. At this time, the upper surface of the float 2 forms a sealing portion 21.

[0062] By arranging the water inlet 121 on the top cover 12 , the float 2 can stably stop against the top cover 12 under the action of the upward buoyancy to reliably block the water inlet 121 , thereby improving the reliability of the water tank assembly 10 .

[0063] Of course, in other embodiments, the water inlet 121 may also be provided on the side wall of the water tank 1, with the side surface of the float 2 forming the blocking portion 21. In this case, when the water level in the water tank 1 is equal to or greater than the first preset value, the side surface of the float 2 contacts the side wall of the water tank 1, causing the blocking portion 21 to block the water inlet 121.

[0064] Alternatively, as Figure 1 、 Figure 3 、 Figure 7 As shown, the top cover 12 is provided with a recessed portion 122 , and the water inlet 121 is provided on the recessed portion 122 .

[0065] On the one hand, when adding water to the water tank 1, water can be poured into the recessed portion 122, allowing water to flow into the interior of the water tank 1 from the water inlet 121, making it easier to add water to the water tank 1. On the other hand, when the water level in the water tank 1 reaches a first preset value, water can continue to be poured into the water tank through the water inlet 121, and the water will be stored in the recessed portion 122, preventing the water from flowing out to the outside, which is beneficial to improving the user experience. In addition, the top cover 12 can be lifted to allow the water stored in the recessed portion 122 to flow into the water tank 1 through the water inlet 121.

[0066] like Figures 1 to 5 As shown, the water tank assembly 10 further includes a mist outlet 4 and a sealing ring 5. The mist outlet 4 is connected to the top cover 12 and is in communication with the mist guide pipe. The mist outlet 4 and the mist guide pipe are sealed by the sealing ring 5.

[0067] Optionally, the mist outlet member 4 is connected to the top cover 12 via a buckle 41 .

[0068] Reference below Figures 1 to 8 A humidifier 100 according to an embodiment of the present invention is introduced.

[0069] like Figure 8 As shown, the humidifier 100 of the embodiment of the present invention includes a base assembly 20;

[0070] The water tank assembly 10 is the water tank assembly 10 described in any of the above embodiments, and the water tank assembly 10 is arranged on the base assembly 20.

[0071] The humidifier 100 of the present embodiment of the utility model is provided with a float 2 within the water tank 1. When the water level within the water tank 1 is equal to or greater than a first preset value, the sealing portion 21 of the float 2 is used to seal the water inlet 121 of the water tank 1, thereby sealing the water inlet 121 and preventing the user from adding water to the water tank 1, thereby preventing the water within the water tank 1 from overflowing from the water tank 1. By arranging the water inlet 121 within the recessed portion 122 of the top cover 12, when the water level within the water tank 1 reaches the first preset value, water can be continued to be added through the water inlet 121. The water will be stored in the recessed portion 122, preventing it from flowing out. Furthermore, by lifting the top cover 12, the water stored in the recessed portion 122 can flow into the water tank 1 through the water inlet 121. Thus, the user experience of the humidifier 100 is improved.
