Description

Technical Field

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

[0002] Humidifiers, used to regulate indoor humidity, have become an essential household appliance. Humidifier water tanks typically feature a filter to remove impurities from the water, minimizing potential blockages in the water and mist paths, and preventing bacterial growth.

[0003] In related technologies, the filter structure is typically fixed at the water outlet at the bottom of the water tank, making it difficult to filter the water introduced into the tank over a large area. This results in poor filtration efficiency and requires frequent cleaning of the water tank, which is time-consuming and labor-intensive. Furthermore, since the filter structure is installed at the bottom of the water tank, it is constantly immersed in water, and impurities within the filter structure can easily lead to secondary contamination of the water.

[0004] Related technologies also propose installing the filter structure in the water tank of the humidifier, but the filter structure is still easily immersed in water, which can also easily lead to secondary contamination of the water, affecting the poor filtering effect. Especially after the filter structure has been used for a period of time, the secondary contamination will be more serious.

[0005] In addition, in the related art, the filter structure is fixed at the bottom of the water tank or inside the water tank, which is difficult to install and disassemble, inconvenient to replace, and the water in the water tank needs to be drained during replacement, resulting in water waste.

[0049] 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.

[0050] like Figures 1-11As shown, the embodiment of the present invention provides a filter, a water tank assembly having the filter, and a humidifier having the water tank assembly. It is understandable that the filter of the embodiment of the present invention is not limited to use in humidifiers, but can also be used in other devices and occasions with similar filtering requirements.

[0051] The filter of the embodiment of the present utility model is first described below.

[0052] like Figure 1-Figure 4 As shown, the filter 100 according to an embodiment of the present invention includes a filter housing 1 and a filter core 2. The filter housing 1 defines a filter chamber 13, which is provided with a water inlet 111 and a water outlet 121. The filter core 2 is disposed within the filter chamber 13. The filter core 2 is configured to filter water entering the filter chamber 13 through the water inlet 111, and the filtered water is discharged from the filter chamber 13 through the water outlet 121. The filter housing 1 and the filter core 2 disposed within the filter chamber 13 are capable of floating on water. In other words, the filter 100 according to the present invention can float on water, and therefore, the filter 100 may also be referred to herein as a floatable filter.

[0053] The filter of the present invention can float on the water surface, thereby reducing the contact probability between the filter core 2 and the filtered water, reducing the secondary contamination of the filtered water by impurities filtered within the filter core 2, and improving the filtering effect. Moreover, because the filter 100 can float on the water surface, it can be used for a long time and the replacement frequency is reduced. Moreover, the replacement of the filter 100 is simple and convenient, saving time and effort, and reducing costs.

[0054] In some embodiments, as Figure 1-Figure 2 As shown, the filter housing 1 is a floatable housing and includes an upper cover 11 and a lower cover 12 . The water inlet 111 is provided on the upper cover 11 , and the water outlet 121 is provided on the lower cover 12 . The upper cover 11 and the lower cover 12 are detachably connected to enclose a filter chamber 13 .

[0055] Specifically, the filter housing 1 floats on the surface of the filtered water, reducing the likelihood of contact between the filter element 2 within the filter cavity 13 and the filtered water, thereby at least to a certain extent reducing secondary contamination of the filtered water by impurities filtered from the filter element 2. The upper cover 11 and the lower cover 12 are detachably connected, making the filter element 2 easy to install and replace within the filter cavity 13. The filter housing 1 has a simple structure, is easy to manufacture, and is cost-effective.

[0056] It is understood that the filter housing 1 is a floatable housing, which means that the filter housing 1 can float on the water surface, thereby achieving that the filter housing 1 and the filter element 2 installed therein can float on the water surface together, that is, the entire filter 100 can float on the water surface. For example, the upper cover 11 and the lower cover 12 can both be made of a floating material, and the floating material can be a plastic material or a foam material. Optionally, one of the upper cover 11 and the lower cover 12 is made of a floating material, or at least a portion of one of the upper cover 11 and the lower cover 12 is made of a floating material. Optionally, the filter housing 1 can also be designed to float by designing its structure, for example, the upper cover 11 and / or the lower cover 12 can be made hollow. It should be pointed out that in the present utility model, "water surface" should be understood in a broad sense. When the filter 100 filters other liquids instead of water, the water surface refers to the liquid level of the other liquid.

[0057] In the embodiment of the present invention, there is no particular limitation on the specific means for achieving the buoyancy of the filter housing 1 , as long as the filter 100 can float on the water surface.

[0058] For example, in some optional embodiments, Figure 1-Figure 2 As shown, the filter housing 1 includes an upper cover 11, a lower cover 12, and a floating member 14. The floating member 14 is used to keep the filter housing 1 and the filter element 2 disposed therein afloat. A water inlet 111 is provided on the upper cover 11, and a water outlet 121 is provided on the lower cover 12. The upper and lower covers 11, 12 are detachably connected to form a filter chamber 13. The connected upper and lower covers 11, 12 are mounted on the floating member 14.

[0059] Specifically, by providing a separate floating component 14, the filter housing 1 and filter element 2 can float together on the surface of the filtered water, reducing secondary contamination of the water by the filter element 2, particularly reducing contamination of the filtered water. The upper cover 11 and lower cover 12 are detachably connected, allowing for easy installation and replacement of the filter element 2 within the filter chamber 13. The floating component 14 can be made of a buoyant material or designed to float.

[0060] When the filter housing 1 is provided with a separate floating component 14, the upper cover 11 and the lower cover 12 may be of a floating type (i.e., made of a floating material), thereby achieving the floating of the filter 100 by means of the floating component 14, the upper cover 11, and the lower cover 12; alternatively, the upper cover 11 and the lower cover 12 may be of a non-floating type (i.e., made of a non-floating material; in other words, the upper cover 11 and the lower cover 12 themselves cannot float), thereby achieving the floating of the entire filter 100 only by means of the floating component 14.

[0061] In some specific examples, such as Figure 1-Figure 2As shown, the upper cover 11, lower cover 12, and floating member 14 are all disc-shaped, more specifically, circular. It should be understood that the shapes of the upper cover 11 and lower cover 12 are not limited to this, as long as the outer contour of the filter 100 is suitable for the application. The upper cover 11 and lower cover 12 are detachably engaged with each other, and at least one of the upper cover 11 and lower cover 12 is engaged with the floating member 14. This results in a simple structure and convenient connection.

[0062] The water inlet holes 111 are multiple groups of arc-shaped holes, which are spaced apart along the circumference of the upper cover 11. The multiple water inlet holes 111 within the same group are spaced apart along the radial direction of the upper cover 11, and the arc lengths of the multiple water inlet holes 111 gradually decrease from the outside to the inside. The water outlet holes 121 are multiple groups of arc-shaped holes, which are spaced apart along the circumference of the upper cover 11. The multiple water outlet holes 121 within the same group are spaced apart along the radial direction of the upper cover 11, and the arc lengths of the multiple water outlet holes 121 gradually decrease from the outside to the inside.

[0063] In the embodiment of the present invention, the upper cover 11, the lower cover 12 and the floating component 14 are all disc-shaped, which can increase the area of ​​the upper cover 11 and the lower cover 12, realize large-area filtration of water by the filter 100, and further improve the filtration efficiency.

[0064] In some embodiments, multiple groups of water inlet holes 111 correspond one-to-one with multiple groups of water outlet holes 121, and multiple water inlet holes 111 in the same group correspond one-to-one with multiple water outlet holes 121 in the same group, which can improve the fluidity of water in the filter 100 and thereby improve the filtration efficiency of the filter 100.

[0065] Preferably, the water inlet 111 and the water outlet 121 are staggered in the direction of water flow, for example Figure 1 The filter elements 100 are staggered in the up and down directions, thereby increasing the flow path of water in the filter 100, extending the filtering time of the water, and further improving the filtering effect.

[0066] In some specific examples, such as Figure 3 As shown, the upper cover 11 includes an upper cover plate 112, a first inner flange 113, and a first outer flange 114. The upper cover plate 112 has a first through-hole 1121. The first inner flange 113 extends downward from the edge of the first through-hole 1121, and the first through-hole 1121 passes through the upper cover plate 112 and the first inner flange 113. The first outer flange 114 extends downward from the outer periphery of the upper cover plate 112. A downwardly extending elastic latch 1141 is provided on the outer edge of the lower surface of the first outer flange 114. The elastic latch 1141 has a latching groove 11411. A downwardly extending inner lower extension 1131 is provided on the outer edge of the lower surface of the first inner flange 113, and a downwardly extending outer lower extension 1142 is provided on the inner edge of the lower surface of the first outer flange 114.

[0067] The first through-hole 1121 is located approximately in the center of the upper cover plate 112, with the central axis of the first through-hole 1121 collinear with the central axis of the upper cover plate 112. Multiple sets of water inlet holes 111 are provided on the upper cover plate 112 and spaced apart along the circumference of the upper cover plate 112. The cross-sectional area of ​​the inner lower extension 1131 is larger than that of the first inner flange 113, while the cross-sectional area of ​​the outer lower extension 1142 is smaller than that of the first outer flange 114. Multiple elastic latches 1141 are provided, spaced apart along the circumference of the first outer flange 114.

[0068] like Figure 4 As shown, the lower cover 12 includes a lower cover plate 122, a second inner flange 123, and a second outer flange 124. The lower cover plate 122 has a second through-hole 1221. The second inner flange 123 extends upward from the edge of the second through-hole 1221, and the second through-hole 1221 passes through the lower cover plate 122 and both the lower cover plate 122 and the inner flange 123. The second outer flange 124 extends upward from the outer periphery of the lower cover plate 122. An upwardly extending inner upper extension 1231 is provided on the inner edge of the upper surface of the second inner flange 123. The inner upper extension 1231 fits within the inner lower extension 1131 and abuts against the lower surface of the first inner flange 113. An upwardly extending outer upper extension 1241 is provided on the outer edge of the upper surface of the second outer flange 124. The outer lower extension 1142 fits within the outer upper extension 1241 and abuts against the upper surface of the second outer flange 124. A groove 12411 penetrating the outer upper extension portion 1241 is formed on the outer circumferential surface of the second outer flange 124 . A latching protrusion 12412 cooperating with the latching slot 11411 is formed in the groove 12411 .

[0069] There may be multiple grooves 12411, which are spaced apart along the circumference of the second outer flange 124. The grooves 12411 correspond one-to-one with the elastic latches 1141. When the upper cover 11 and the lower cover 12 are mated, the elastic latches 1141 fit within the grooves 12411, and the latching protrusions 12412 engage with the latching slots 11411, making the mating of the upper cover 11 and the lower cover 12 simple and effective, and facilitating assembly and disassembly.

[0070] The second through-hole 1221 is located approximately in the middle of the lower cover plate 122, and the central axis of the second through-hole 1221, the central axis of the lower cover plate 122, the central axis of the first through-hole 1121, and the central axis of the upper cover plate 112 are collinear. Multiple groups of water outlet holes 121 are provided on the lower cover plate 122 and are spaced apart along the circumference of the lower cover plate 122. The cross-sectional area of ​​the second inner flange 123 can be the same as that of the first inner flange 113, and the cross-sectional area of ​​the inner upper extension 1231 is smaller than that of the second inner flange 123, so that the inner upper extension 1231 can be sleeved with the inner lower extension 1131, thereby improving the reliability of the fit between the upper cover 11 and the lower cover 12. Figure 7As shown, the inner upper extension portion 1231 can stop against the lower surface of the first inner flange 113, thereby playing a limiting role.

[0071] The cross-sectional area of ​​the second outer flange 124 is the same as that of the first outer flange 114. The cross-sectional area of ​​the outer upper extension 1241 is larger than that of the second outer flange 124, allowing the outer upper extension 1241 to be nested with the outer lower extension 1142, further improving the secure fit between the upper cover 11 and the lower cover 12. The outer upper extension 1141 can abut against the upper surface of the second outer flange 124, thereby acting as a limiter.

[0072] like Figure 5-Figure 7 As shown, the inner circumferential surface of the first through-hole 1121 is provided with an inner groove 11211 adjacent to the upper end of the first through-hole 1121. The floating component 14 includes an annular outer float 141, an inner float 142 having a third through-hole 1422, and a connecting float rod 143. The inner float 142 is located within the outer float 141 and is connected by the connecting float rod 143. Both the inner float 142 and the outer float 141 are hollow to reduce weight and increase buoyancy. Preferably, the connecting float rod 143 can also be a hollow rod to further reduce weight and increase buoyancy. An accommodating space 144 is formed between the inner float 142 and the outer float 141, and the upper cover 11 and the lower cover 12 are located in the accommodating space 144. The inner float 142 is provided with an inner locking protrusion 1421 adjacent to the upper end of the inner float 142. The inner float 142 passes through and fits in the first through-hole 1121 and the second through-hole 1221, and the inner locking protrusion 1421 cooperates with the inner locking groove 11211.

[0073] There can be multiple connecting floats 143, and the multiple connecting floats 143 are arranged at intervals along the circumference of the inner float 142. One end of the connecting float 143 is connected to the inner float 142, and the other end of the connecting float 143 is connected to the outer float 141. The intervals between adjacent connecting floats 143 facilitate the passage of water.

[0074] There may be multiple inner engaging grooves 11211, and the multiple inner engaging grooves 11211 are arranged at intervals along the circumference of the first through-hole 1121. There may be multiple inner engaging protrusions 1421, and the multiple inner engaging protrusions 1421 are arranged at intervals along the circumference of the inner float 142. The multiple inner engaging protrusions 1421 correspond one-to-one with the multiple inner engaging grooves 11211. Through the cooperation between the internal engaging grooves 11211 and the internal engaging protrusions 1421, the inner float 142 and the upper cover 11 are connected to each other, which simplifies the connection method and improves the reliability of the connection between the upper cover 11, the lower cover 12, and the floating member 14.

[0075] The outer float 141 and the inner float 142 are both hollow, which reduces the mass of the floating component 14 and the volume of the floating component 14 submerged below the water surface, further ensuring that impurities in the filter core 2 are not easily in contact with the filtered water.

[0076] In some embodiments, as Figure 2 As shown, the filter core 2 includes a filter mesh 21 and filter particles 22 . The filter particles 22 are accommodated in the filter cavity 13 , and the filter mesh 21 is arranged on the water inlet side of the filter particles 22 .

[0077] Specifically, the filter mesh 21 is laid on the water inlet side of the filter particles 22. The water is first filtered through the filter mesh 21, and then other impurities in the water are adsorbed and filtered through the filter particles 22, thereby further improving the filtering effect.

[0078] Specifically, the filter particles 22 can be quartz sand, gravel, anthracite, manganese sand, magnetite filter material, fruit shell filter material, porcelain sand filter material, ceramsite, medical stone filter material, etc. Preferably, the filter particles 22 are medical stone filter material.

[0079] In some preferred embodiments, when the filter housing 1 and filter core 2 float on the water, the lower surface of the filter core 2 remains above the water surface and does not come into contact with the filtered water. For example, by increasing the thickness of the float member 14 and / or the buoyancy generated, only a portion of the float member 14 can be submerged in the water when the filter 100 floats. Alternatively, if the float member 14 is not provided and the filter 100 is floated solely by the upper cover 11 and the lower cover 12, only a portion of the lower cover 11 can be submerged in the water, keeping the filter core 2 above the water surface within the filter housing, thereby preventing the filter core 2 from coming into contact with the filtered water.

[0080] The above arrangement prevents the filter core 2 from contacting the filtered water, and better prevents the impurities in the filter core 2 from secondary contamination of the filtered water.

[0081] The water tank assembly according to an embodiment of the present invention is described below.

[0082] like Figures 8-10 As shown, the water tank assembly of the embodiment of the present invention includes a water tank 3 and a filter 100. The filter 100 can be the filter 100 of the above embodiment.

[0083] The upper part of the water tank 3 has a water filling hole 321, and the lower part of the water tank 3 has a drainage hole (not shown). The filter 100 is arranged in the water tank 3 and the outer wall surface of the filter 100 is slidably matched with the inner wall surface of the water tank 3. The filter 100 can float on the surface of the filtered water in the water tank 3 and move up and down as the water level in the water tank 3 changes.

[0084] In the water tank assembly of the present invention, the outer wall of the filter 100 is slidably engaged with the inner wall of the water tank 3. This prevents water from bypassing the filter 100 through the gap between the filter 100 and the water tank 3, thereby ensuring effective filtration. Furthermore, it increases the contact area between the filter 100 and the water, thereby improving filtration efficiency. When water is added to the water tank 3 through the water inlet 321, the filter 100 can filter the water over a large area, thereby improving filtration efficiency. The filter 100 can float on the water surface and move up and down with changes in the water level, thereby reducing secondary contamination of the filtered water by impurities within the filter 100. This ensures effective filtration, extends the service life of the filter 100, and reduces the frequency of filter 100 replacement. Furthermore, since the filter 100 floats on the water surface, it is easy to replace. There is no need to empty the water in the water tank 3 when replacing the filter, making operation simple and convenient, and reducing water waste.

[0085] In some specific examples, the water tank 3 includes a tank body 31 and a tank cover 32. The tank cover 32 covers the top of the tank body 31 to cover the upper opening of the tank body 31. The water filling hole 321 is provided on the tank cover 32, and the drainage hole is provided on the bottom wall of the tank body 31. The tank cover 32 is gradually concave in a direction from the periphery to the center.

[0086] There may be multiple water addition holes 321, which are spaced apart along the circumference of the box cover 32. The box cover 32 is located at the top of the box body 31. When water is added to the box body 31, the water gathers toward the concave center of the box cover 32 and flows into the box body 31 through the water addition holes 321, making it difficult for the water to overflow, thereby ensuring the filtration effect. In addition, the filter 100 can filter water over a large area, further improving the filtration effect.

[0087] In some embodiments, for example, when the water tank 3 is the water tank of the humidifier 100, the water tank assembly 200 may further include a mist outlet conduit 4 and a mist outlet cap 5. The top surface of the mist outlet cap 5 is provided with a mist outlet hole 51, and the tank cover 32 is provided with a connecting hole 322. The mist outlet conduit 4 is provided in the water tank 3, and the mist outlet cap 5 is mounted on the tank cover 32. The lower end of the mist outlet cap 5 fits in the connecting hole 322. The upper end of the mist outlet conduit 4 is connected to the lower end of the mist outlet cap 5 via a seal 6. The filter 100 is sleeved on the outside of the mist outlet conduit 4 and slidably engages with the mist outlet conduit 4.

[0088] like Figure 11 As shown, the connection hole 322 is located at the center of the box cover 32. The central axis of the connection hole 322 is collinear with the central axis of the mist outlet conduit 4, so that the mist outlet conduit 4 and the mist outlet cap 5 can be matched. A seal 6 is provided between the mist outlet conduit 4 and the mist outlet cap 5, and the seal 6 is arranged around the circumference of the lower end of the mist outlet cap 5 to prevent water from entering the mist outlet conduit 4.

[0089] The filter 100 is sleeved on the mist outlet conduit 4 and slides with the mist outlet conduit 4. The mist outlet conduit 4 can play a guiding role, so that the filter 100 is not easily deflected when it moves up and down with the water level, and water is not easy to bypass the filter 100 through the gap between the filter 100 and the mist outlet conduit 4, thereby improving the filtering effect.

[0090] The humidifier according to the embodiment of the present invention includes the filter 100 according to the embodiment described above.

[0091] In the humidifier of the embodiment of the present invention, the filter 100 has a large filtering area and is not easily in contact with the filtered water, thereby improving the efficiency and effect of the humidifier 300 in filtering water and preventing the filtered water from being contaminated again.

[0092] The humidifier according to the embodiment of the present invention may include the water tank assembly 200 according to the above embodiment.

[0093] like Figure 11 As shown, the humidifier 300 of the embodiment of the present invention includes a base 7, and the water tank 3 of the water tank assembly 200 is arranged on the base 7. The filter 100 of the water tank assembly 200 has high water filtering efficiency and can ensure that the filtered water is not easily contaminated by secondary pollution, thereby improving the water filtering effect of the humidifier 300. In addition, the water channel and water mist channel of the humidifier 300 are not easily blocked, thereby increasing the service life of the humidifier 300, reducing the maintenance frequency, saving time and effort, and reducing costs.
