Description

Technical Field

[0001] This utility model belongs to the field of humidifier technology, specifically relating to a filter assembly and a humidifier. Background Technology

[0002] A humidifier is a device used to humidify the air. Humidifiers generally use a fan to drive air through a damp filter, thereby increasing the humidity of the air and achieving the purpose of humidifying the air.

[0003] To keep the filter screen moist, there are currently two main solutions on the market: one is to use a water pump to siphon water and wet the filter screen. In this solution, the filter screen has a relatively high humidity and the overall humidity of the filter screen is relatively uniform. However, a water pump is required, and the water pump will generate some noise during the water pumping process. The other solution is to immerse at least part of the filter screen in the water tank and use the filter screen's own water absorption property to siphon water and wet the filter screen. In this solution, the humidity of the filter screen will be uneven due to different water levels in the water tank. In particular, when the water level in the water tank is low, the filter screen may not be able to absorb water, which will affect the efficiency of air humidification. Utility Model Content

[0032] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0033] Example 1 See Figures 1 to 6 This utility model discloses a filter assembly, including: a support 10, which is a ring-shaped sleeve structure, the support 10 including a main body 101 and a folding part 102 connected to each other, the folding part 102 is disposed at the first end of the main body 101 and folds outward from the main body 101, forming a first mounting part 103 between the folding part 102 and the main body 101, the main body 101 is provided with a first ventilation hole 111 extending in its radial direction, the center of the main body 101 is provided with a second ventilation hole 112 extending in its axial direction, the first ventilation hole 111 and the second ventilation hole 112 are interconnected; a filter 20, which is disposed inside the first mounting part 103; and a float 30, which is disposed outside the folding part 102.

[0034] The filter assembly of this utility model includes a float 30, which drives the entire filter assembly to move up and down with the water level, so that the filter 20 can always absorb water to maintain humidity. The bracket 10 not only supports the filter 20 and the float 30, but also enables air intake and flow. The filter 20 is located inside the first mounting part 103, and the float 30 is located outside the folding part 102. The two do not affect each other. The float 30 can be made larger to provide greater buoyancy, and the filter 20 can also be made larger to ensure that the filter assembly has a large air passage.

[0035] It should be noted that the filter 20 can be a single-layer or multi-layer structure, and can be a textile fiber filter or a metal filter. Its specific filtration principle is existing technology and will not be elaborated here. The filter 20 can filter air; when the filter 20 is moist, it can not only filter the air but also humidify it.

[0036] See Figures 1 to 5 The first end of the main body 101 is the lower end of the main body 101. Therefore, the folding part 102 is set at the lower end of the main body 101. When in use, the filter screen assembly is placed in the water tank 80. The water tank 80 contains water for humidifying the air. As a result, the float 30 floats on the water surface due to its own buoyancy. The float 30 drives the filter screen 20 and the bracket 10 to move up and down with the water level, so that the filter screen 20 can always absorb water to maintain humidity.

[0037] Continue reading Figures 1 to 5 The upper end of the second ventilation hole 112 faces the outside. Multiple first ventilation holes 111 are provided to allow air to enter, and one second ventilation hole 112 is provided. Outside air is filtered through the moist filter 20, humidified once, and then enters the first ventilation hole 111 and converges into the second ventilation hole 112. The lower end of the second ventilation hole 112 faces the water surface, and some water vapor enters the second ventilation hole 112 directly from the water surface to humidify the air a second time. Finally, the filtered and humidified air is discharged from the upper end of the second ventilation hole 112. The humidification effect of this filter assembly is better.

[0038] In this embodiment of the present invention, the folding portion 102 includes a first bending segment 121, a second bending segment 122, and a third bending segment 123 connected in sequence; the first end of the first bending segment 121 is connected to the first end of the main body 101, and the first bending segment 121 extends along the radial direction of the main body 101; the second end of the first bending segment 121 is connected to the first end of the second bending segment 122, and the second bending segment 122 extends along the axial direction of the main body 101; the second end of the second bending segment 122 is connected to the first end of the third bending segment 123, and the third bending segment 123 extends along the radial direction of the main body 101.

[0039] See Figures 2 to 5 The first bending segment 121, the second bending segment 122, and the third bending segment 123 are integrated into one structure, making the bracket 10 in an inverted "T" shape, which makes the bracket 10 smaller at the top and larger at the bottom, resulting in strong overall stability.

[0040] In this embodiment of the present invention, a first bending segment 121 is disposed on the inner side of the first end of the second bending segment 122 to form a first mounting portion 103, and a third bending segment 123 is disposed on the outer side of the second end of the second bending segment 122 to form a second mounting portion 104 for mounting the floating component 30.

[0041] See Figures 2 to 5 The filter screen 20 is located on the inner side of the folded part 102 near the main body 101, and the float 30 is located on the outer side of the folded part 102 away from the main body 101, so that the installation of the filter screen 20 and the float 30 do not affect each other.

[0042] In this embodiment of the utility model, the float 30 is a ring sleeve structure. The float 30 is disposed inside the second mounting part 104 and sleeved outside the second bending section 122. The end face of the first end of the float 30 away from the main body 101 abuts against the third bending section 123.

[0043] See Figures 2 to 5 During installation, the float 30 is inserted from bottom to top onto the outside of the second bent section 122 until the upper end face of the float 30 abuts against the third bent section 123, thereby limiting the installation of the float 30 by the third bent section 123. Based on the above structure, when the float 30 and the bracket 10 are detachably connected, the user can easily assemble and disassemble the float 30.

[0044] In this embodiment of the present invention, a first opening 124 for the filter screen 20 to be exposed is provided on the first bending section 121, and / or a second opening 125 for the filter screen 20 to be exposed is provided on the second bending section 122; the lowest position of the float 30 is higher than the lowest position of the first opening 124 and / or the second opening 125, the portion of the filter screen 20 close to the first opening 124 and / or the second opening 125 forms a water absorption area 201, and the portion of the filter screen 20 away from the first opening 124 and / or the second opening 125 forms a siphon area 202.

[0045] See Figures 2 to 5 The first bend 121 is provided with a first opening 124 for the filter screen 20 to be exposed, and the second bend 122 is provided with a second opening 125 for the filter screen 20 to be exposed. There are multiple first openings 124 and second openings 125. Since the lowest position of the float 30 is higher than the lowest position of the first opening 124 and / or the second opening 125, when the water level in the water tank 80 is low, the filter screen 20 can still be exposed through the first opening 124 and / or the second opening 125 to contact the water in the water tank 80 and absorb water. Thus, the filter screen 20 absorbs as much water as possible from the bottom of the water tank 80.

[0046] In this embodiment of the utility model, the bracket 10 further includes an end cap 40, which is an annular sleeve structure; the filter screen 20, the main body 101, and the folding part 102 are all annular sleeve structures; the end cap 40 is detachably disposed at the second end of the main body 101, and the end cap 40, the main body 101, and the folding part 102 form an installation space 50 for installing the filter screen 20.

[0047] See Figures 2 to 5 The installation space 50 is an annular space, which is adapted to the filter screen 20. The second end of the main body 101 is the upper end of the main body 101. Therefore, the end cap 40 is detachably installed on the upper end of the main body 101. When the filter screen 20 is sleeved on the outside of the main body 101 and cooperates with the first mounting part 103, the end cap 40 is used to fix the filter screen 20.

[0048] In this embodiment of the utility model, the outer diameter of the end cap 40 is D1, the outer diameter of the filter screen 20 is D2, and D1≥D2.

[0049] See Figure 1 , Figure 2 as well as Figure 7 , Figure 8 D1 > D2, thus the end cap 40 protrudes beyond the outer side of the filter screen 20. In other words, sufficient air intake space 90 is reserved between the end cap 40 and the outer side of the filter screen 20. Figure 7 , Figure 8When the guide member 100 is used to guide the up-and-down movement of the filter screen 20, the filter screen 20 will not stick tightly to the guide member 100, thus ensuring the air intake of the filter screen assembly.

[0050] In this embodiment of the present invention, the end cap 40 is provided with a third mounting portion 401 and a fourth mounting portion 402 on the end face facing the folding portion 102; the third mounting portion 401 is used to detachably connect with the second end of the main body 101; the first end of the filter screen 20 is inserted into the interior of the first mounting portion 103, and the second end of the filter screen 20 is inserted into the interior of the fourth mounting portion 402.

[0051] Thus, the filter screen 20 is fitted onto the outside of the main body 101, and the filter screen 20 is fixed by "the lower end being inserted into the first mounting part 103 and the upper end being inserted into the fourth mounting part 402". The actual installation space 50 is "the annular space formed by the first mounting part 103 (folding part 102 side), the fourth mounting part 402 (end cover 40 side) and the outer periphery of the main body 101".

[0052] In this embodiment of the utility model, the float 30 is a hollow structure, such as a hollow plastic structure. The buoyancy of the float 30 is greater than the overall weight of the filter assembly, so the filter assembly can float on the water surface under the action of the buoyancy of the float 30.

[0053] Example 2 See Figures 1 to 8 This utility model discloses a humidifier, including the above-mentioned filter assembly.

[0054] The humidifier of this invention uses the above-mentioned filter assembly, which has a better humidification effect.

[0055] See Figures 7 to 8 The humidifier also includes a housing 60, a fan assembly 70, and a water tank 80. The housing 60 has an air inlet 601 on its side, which is connected to a first ventilation hole 111. The housing 60 has an air outlet 602 on its upper part, which is connected to a second ventilation hole 112. The fan assembly 70 is located in the upper part of the inner cavity of the housing 60, the filter assembly is located in the middle part of the inner cavity of the housing 60, and the water tank 80 is located in the lower part of the inner cavity of the housing 60. The fan assembly 70 is located between the air inlet 601 and the air outlet 602. Air outside the housing 60 is discharged to the outside of the housing 60 after passing through the air inlet 601, the filter assembly, the fan assembly 70, and the air outlet 602.

[0056] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
