Description

Technical Field

[0001] The present disclosure relates to the technical field of humidifiers, and in particular to a humidifying filter element and a humidifier. Background Art

[0002] A humidifier can be used to humidify indoor or outdoor air. Generally, a humidifier can have a water tank and a humidification filter element. The water in the water tank can be transported to the humidification filter element to wet the humidification filter element. When air passes through the humidification filter element, it can take away some water vapor from the humidification filter element to form humidified air, which flows out from the air outlet of the humidifier, achieving the effect of humidifying the ambient air.

[0003] In the related art, the humidification filter element generally has a water distribution structure, which can control the water flow to gradually penetrate and diffuse from different positions to the lower part of the humidification filter element, thereby fully wetting the humidification filter element.

[0004] However, the water flow velocity and flow rate in different parts of the humidification filter may be different. Water easily comes into contact with air at the diffusion edge to form scale, which is easily deposited, resulting in a reduced service life of the humidifier. Utility Model Content

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0038] The directional nouns involved in the embodiments of the present disclosure, such as "upper", "lower", "side", etc., are generally based on the relative directional relationship between the structures when the humidifier or humidification filter is usually arranged, and these directional nouns are used only to more clearly describe the relationship between the structures, and are not intended to describe the absolute direction. When the humidifier or humidification filter is placed in different postures, the direction may change, for example, "upper" and "lower" may be interchangeable.

[0039] It should be noted that in the embodiments of the present disclosure, the "inside" and "outside" involved are generally based on the central axis or center of the humidifier or humidification filter element, the side closer to the central axis or center is the inside, and the side farther away from the central axis or center is the outside. In the embodiments of the present disclosure, the "upper", "lower", "high", "low", "top" or "bottom" involved are generally based on the ground, the end or side closer to the ground is the "upper side", "upper end" or "higher end" or "top end", and the end or side farther away from the ground is the "lower side", "lower end", "lower end", "bottom end" or "bottom".

[0040] Unless otherwise defined, all technical terms used in the embodiments of the present disclosure have the same meanings as commonly understood by those of ordinary skill in the art.

[0041] In order to make the technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0042] The humidification filter element involved in the embodiment of the present disclosure can be applied to the field of evaporative humidifiers.

[0043] Evaporative humidifiers rely on the natural evaporation of liquid water to increase the humidity of the air. The humidifier may include a water tank and a humidification filter element. Water can be added to the water tank from the water inlet. The water tank is provided with a water pump. The water pump can pump the water in the water tank into the water balancing tank through the upper water hole of the water balancing tank on the upper part of the humidification filter element. A lower water hole may be provided at the bottom of the water balancing tank. Water can fall from the lower water hole onto the humidification filter element to moisten the humidification filter element. Wind enters from the air inlet of the humidifier. Driven by the impeller, it can pass through the humidification filter element and take away the water molecules therein, thereby moistening the air. The moist air is discharged from the air outlet by the humidifier, thereby humidifying the ambient air.

[0044] However, there is inevitably a distance between different drain holes in the water balancing tank. If the distance is too small, the amount of water discharged from the filter body close to the upper water hole is large, while the amount of water discharged from the filter body far from the upper water hole is small, resulting in very uneven water discharge from different parts of the filter body. If the above problem is circumvented by increasing the distance between the drain holes, it is easy to cause the drain holes to be blocked. In addition, combined with Figure 6 , due to the spacing between the drainage holes 01, the water flowing down in the direction indicated by the downward arrow will form a roughly trapezoidal drainage area boundary 02 (or drainage diffusion edge). The drainage area boundaries 02 corresponding to different drainage holes 01 (such as Figure 6 At the diffusion edge, water and air have more contact area and opportunities, making it easier to form scale composed of calcium carbonate or magnesium carbonate. Since the water flow rate at the diffusion edge of the downflow is slow, the water flow at the diffusion edge cannot effectively flush the high-concentration salt water formed after evaporation, and thus the area at the diffusion edge that is relatively downstream of the downflow (i.e., the area inside the boundary of the trapezoidal downflow area) is more likely to form stable crystal nuclei, and the scaling rate is faster.

[0045] In order to reduce scale formation, it is necessary to increase the uniformity of water flowing downward from the top of the humidification filter as much as possible.

[0046] To this end, in a first aspect, the present disclosure provides a humidification filter element. Figure 1-2 The humidifying filter element comprises a filter element body 1 and a water distribution structure 2, and the water distribution structure 2 is installed on the upper part of the filter element body 1;

[0047] The water distribution structure 2 includes an upper water inlet 21, a water distribution trough 22 and at least one lower water inlet 23. The upper water inlet 21 is configured to guide water into the water distribution trough 22. The side of the water distribution trough 22 close to the lower water inlet 23 has an overflow structure 221. The lower water inlet 23 guides water to the filter element body 1.

[0048] In this embodiment, the function of the water inlet is to transport the water pumped by the humidifier water tank pump to the water equalizing tank, the function of the water equalizing tank is to transport the water pumped up by the water pump to the water outlet, and the function of the water outlet is to make the water in the water equalizing tank fall onto the filter element body, wherein the filter element body is a water-absorbing material.

[0049] With the help of the above humidification filter element, it can be ensured that when water enters the water balancing tank from the upper water inlet, it will first accumulate in the water balancing tank until the water level reaches the overflow height corresponding to the overflow structure. At this time, water at different positions will flow out of the lower water outlet along the overflow structure at the same time. The overflow structure can be set at various positions of the water balancing tank, or set continuously, so that water can diffuse and penetrate evenly into the filter element body, the longitudinal flow velocity of the water flow is greater, and the lateral diffusion of the water flow is weakened, which can effectively flush the scale, reduce the accumulation of scale, and slow down the CO2 emission during a single cycle. 2 The rapid flushing of water makes it difficult for the high-concentration salt water formed in the late stage of evaporation to form stable crystal nuclei on the membrane surface, thereby slowing down the condensation speed of scale on the filter element.

[0050] In summary, the embodiments of the present invention provide a humidifying filter element, and a water equalizing structure is installed on the upper part of the filter element body of the humidifying filter element. The upper water inlet of the water equalizing structure can inject water into the water equalizing tank. The water equalizing tank has an overflow structure. With the help of the overflow structure, it can be ensured that the water in the water equalizing tank overflows from the overflow structure at the same time when it is higher than a certain water level, and then the overflowed water can reach each drain port more evenly, ensuring that the water is distributed more evenly when the humidifying filter element is wetted, and scale is not easy to generate. When the water equalizing tank is full of water, the overflowing water flow can be maintained at a higher flow rate, so that the scale that may exist on the humidifying filter element can be effectively washed away, and the service life of the humidifier is longer.

[0051] Optional, combined Figure 2 and Figure 5 The overflow structure 221 includes at least one of an overflow hole 2211 and an overflow notch 2212 formed on the wall of the water balancing trough 22 .

[0052] Some optional specific implementations of the overflow structure are given above, which have low preparation costs and good overflow effects. Those skilled in the art can make more diverse designs according to actual needs.

[0053] Optional, combined Figure 5 b. The overflow structure 221 includes a plurality of overflow holes 2211, and the distances between the plurality of overflow holes 2211 and the top of the filter element body 1 are the same, and the plurality of overflow holes 2211 are evenly spaced. This ensures that the time when each part of the water balancing tank begins to overflow is the same, and the amount of overflow is more uniform at each position, thereby further improving the uniformity of water discharge.

[0054] Optional, combined Figure 2 or Figure 5c. The overflow structure 221 includes a plurality of overflow notches 2212, and the minimum distance between the plurality of overflow notches 2212 and the top of the filter element body 1 is the same. By setting the minimum distance between the overflow notches and the top of the filter element body to be the same, it can be ensured that each overflow notch starts to overflow at the same time, and the overflow flow rate is consistent, which is conducive to further improving the uniformity of water discharge.

[0055] Optionally, the gap shape of the overflow gap 2212 includes at least one of a triangle, a rectangle, a semicircle, an arc, and a trapezoid. Here are several optional gap shapes, and those skilled in the art can also choose more other gap shapes according to needs, which will not be repeated here.

[0056] Optional, combined Figure 5 c. The multiple overflow notches 2212 have the same size and are arranged continuously. This can further ensure the uniformity of the water discharge. For the cylindrical humidification filter element and the water-distributing structure, the above arrangement can ensure that the water discharge velocity of the humidification filter element is more uniform within the full 360° angle range.

[0057] Optional, combined Figure 2-3 The overflow structure 221 includes a continuous sawtooth structure or a continuous wave structure at the top of the groove wall of the water averaging groove 22. The continuous sawtooth structure or wave structure can further improve the synchronization of overflow at each position, and the overflow flow rate and flow rate at each position are more uniform, which is conducive to further reducing the probability of scale formation.

[0058] Optional, combined Figure 5 a. The water balancing tank 22 has a first side wall 222 and a second side wall 223 opposite to each other. The height of the first side wall 222 is lower than that of the second side wall 223. The drain port 23 is located on a side of the first side wall 222 away from the second side wall 223. The first side wall 222 serves as an overflow structure 221.

[0059] In this embodiment, when the water level in the water balancing tank is equal to the height of the first side wall, water begins to overflow from one side of the first side wall. This allows the overflow design to be implemented with a simple structure and at a relatively low cost, thereby improving the uniformity of water discharge.

[0060] In some embodiments, in combination Figure 1-2 , the water-distributing structure 2 further includes a first packaging member 25 and a first reinforcement member 24;

[0061] There are multiple water outlets 23 located between the first packaging component 25 and the water balancing tank 22 . A first reinforcement member 24 is provided between every two adjacent water outlets 23 . The first reinforcement member 24 is connected to the water balancing tank 22 and the first packaging component 25 , respectively.

[0062] In this embodiment, different drain outlets are separated by a first reinforcement member, and the water balancing tank and the first packaging member can be connected by means of the first reinforcement member, so that the installation of the water balancing structure as a whole is relatively convenient. At the same time, the first reinforcement member can ensure that the rigidity of the water balancing structure as a whole is good, and the opening of the drain outlet is large, and the water flow rate and uniformity are good.

[0063] Optional, combined Figure 3 The water outlet 23 is formed in a strip shape. The strip-shaped water outlet is beneficial to avoid the contact between the water and the air, and to increase the flow rate of the water, which is beneficial to flushing away the scale in the humidification filter element.

[0064] Optional, combined Figure 3 , the extension direction of the strip-shaped drain port 23 (such as Figure 3 The direction of extension of the top of the filter element body 1 (indicated by the arrow x in the middle) is the same as the direction of extension of the top of the filter element body 1 (indicated by the arrow x in the middle) Figure 3 In this way, the filter element body can be wetted more efficiently and evenly by the water flowing down the drain outlet. Here, the extension direction of the strip drain outlet refers to the extension direction of the strip length; the extension direction of the top of the filter element body refers to the extension direction of one side of the filter element body that is installed in cooperation with the water distribution structure. Figure 1 and 3 When the filter element body is enclosed in a cylindrical shape, its top extends along an arc shape, and the length direction of the strip drain outlet can also extend along the arc shape; when the filter element body is in a sheet shape, its top extends along a straight line, and the length direction of the strip drain outlet can also extend along a straight line.

[0065] Optional, combined Figure 4 , the water inlet 21 is located at the bottom of the water balancing tank 22. Here is a specific implementation of the water inlet setting position. In practice, those skilled in the art can also adjust the position of the water inlet according to needs, and only need to ensure that the water inlet can guide water into the water balancing tank.

[0066] In some embodiments, in combination Figure 3-4 The water distribution structure 2 further includes a cover 26, which encapsulates the water distribution tank 22, the lower water port 23 and the upper water port 21. With the help of the cover, the appearance of the water distribution structure can be improved and the working stability of the water distribution structure can be ensured.

[0067] Optional, combined Figure 4 The water distribution structure 2 further includes a first mounting groove 27 , and the cover body 26 further includes a second mounting member 261 , which is installed in the first mounting groove 27 .

[0068] The cooperation between the first installation groove and the second installation member is helpful to improve the installation efficiency of the cover body.

[0069] Optionally, the number of first mounting grooves 27 and second mounting members 261 are both two, and each second mounting member 261 is installed in a first mounting groove 27, wherein one first mounting groove 27 is located on the side of the water balancing groove 22 away from the drain port 23, and the other first mounting groove 27 is located on the side of the drain port 23 away from the water balancing groove 22.

[0070] Based on the above arrangement, it is beneficial to improve the installation stability of the cover body, and at the same time, improve the packaging effect of the cover body on structures such as the water balancing tank, thereby avoiding water splashing and the like.

[0071] Optional, combined Figure 1-2 The top of the filter element body 1 and the water distribution structure 2 are both formed in a ring shape. This can increase the water vapor content taken away when the air passes through the filter element body, thereby improving the humidification efficiency of the humidifier.

[0072] In summary, the embodiments of the present disclosure provide a humidification filter element having a water distribution structure. The structural characteristics of the water distribution structure can effectively ensure the uniformity of water discharge, avoid the formation of scale due to contact between water and air, and thus increase the service life of the humidification filter element.

[0073] In a second aspect, an embodiment of the present disclosure provides a humidifier, which includes any one of the humidification filter elements described above.

[0074] To sum up, the embodiments of the present disclosure provide a humidifier, the humidification filter element of the humidifier has a water distribution structure, and the structural characteristics of the water distribution structure can effectively ensure the uniformity of water discharge, avoid the formation of scale when water and air come into contact, and thus increase the service life of the humidification filter element and the humidifier.
