Description

Technical Field

[0001] This utility model relates to the field of air humidification technology, specifically to a liquid holding element and an air humidification device. Background Technology

[0002] In the field of household air humidifiers, evaporative humidifier filters are a common type of humidifier component. Their principle is based on physical adsorption and natural evaporation; the filter absorbs moisture and allows the air flowing through it to come into contact with it, thus achieving the effect of humidifying the air. For example... Figure 1 As shown, a typical evaporative humidifier filter is designed as a multi-layered, three-dimensional structure. As a common form, it includes a filter 1001 folded into multiple layers and end caps 1002 fixed to the upper and lower ends. The filter 1001 is enclosed in a cylindrical shape to ensure structural stability. The filter 1001 is typically made of absorbent materials such as high-density fibers, sponge, non-woven fabric, or ceramics.

[0003] Typically, these types of evaporative humidifying filters are moistened in two ways: absorption and spraying. In the absorption method, a water-receiving tray is located below the filter 1001, and the filter 1001 is placed in the tray (or rotated) to come into contact with the water. The filter 1001 absorbs moisture through its own material, thus achieving humidification. In the spraying method, a water outlet is located above the filter 1001, directly delivering water to the filter 1001, thus achieving humidification. Designers in the art can determine whether to use the absorption or spraying method for humidification based on various design requirements and material selections.

[0004] However, the humidification effect of this type of evaporative humidifier filter has its limits, and it often cannot be achieved when designers require higher humidification efficiency. On the other hand, under long-term humidification conditions, this type of evaporative humidifier filter is prone to scale buildup or material aging, and usually needs to be replaced every few months, resulting in relatively high maintenance costs.

[0005] The purpose of this invention is to provide a liquid holding element that can achieve higher humidification efficiency, while also having higher durability and ease of maintenance, thus satisfying the user's experience. Utility Model Content

In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0045] Below, the embodiments of the liquid holding element 100 claimed in this application will be described in general terms.

[0046] Please refer to the following first. Figure 8 , Figure 8This is a three-dimensional structural schematic diagram of the liquid holding element 100 provided by this utility model. The main function of the liquid holding element 100 is to contact the liquid and keep (or can be understood as short-term preservation or retention) the liquid on itself. As a common approach, when air passes through the liquid holding element 100, it can fully contact the liquid being held, and the liquid is carried by the air to achieve higher evaporation of moisture, thereby increasing the humidity of the airflow. In this way, the humidification effect of the air is ultimately improved.

[0047] like Figure 8 As shown, the liquid holding element 100 is cylindrical in shape. Here, cylindrical shape refers to a wraparound shape with openings at the top and bottom (i.e., ventilation openings 140). Furthermore, this application does not limit whether the cylindrical shape is stable. That is to say, it can be a relatively stable cylinder or a soft or elastic cylinder with an unstable shape. This is generally determined by the material or material parameters used to manufacture the liquid holding element 100.

[0048] Before describing the specific structure and features of the liquid holding element 100, we will first describe the local structural features of the liquid holding element 100. This is the main structure that enables the liquid to be held.

[0049] Please refer to the following. Figures 2 to 7 The local structural features of the liquid holding element 100 are described. Figure 2 This is a partially enlarged structural schematic diagram of the liquid holding element 100 provided in the first embodiment of this utility model; Figure 3 Based on Figure 2 A schematic diagram of the structure of a single substrate opening 111; Figure 4 This is a partial view of the liquid holding element 100 provided in the first embodiment of the present invention, viewed from the substrate layer 110. Figure 5 This is a partial view of the liquid holding element 100 provided in the first embodiment of the present invention, viewed from the liquid holding portion 120. Figure 6 This is a partially enlarged structural schematic diagram of the liquid holding element 100 provided in the second embodiment of this utility model; Figure 7 This is a partially enlarged structural schematic diagram of the liquid holding element 100 provided in the third embodiment of this utility model.

[0050] Figures 2 to 7 It can be understood as Figure 8 An enlarged view of a portion of a local area D of the upper liquid holding element 100.

[0051] Please refer to Figure 2The liquid holding element 100 includes a substrate layer 110 and a liquid holding portion 120, wherein the liquid holding portion 120 is composed of multiple strands of filaments. In this embodiment, each strand of filament is wound into a loop 121. In other embodiments, the filaments may be strip-shaped or arc-shaped.

[0052] Please refer to Figure 3 , Figure 3 Based on Figure 2 A schematic diagram of a single substrate opening 111 is shown. The substrate layer 110 can be woven from yarn, and multiple substrate openings 111 are densely arranged on the substrate layer 110. The substrate openings 111 are used to allow air to blow through, thereby allowing more air to contact the liquid holding element 100. At the same time, airflow can blow through multiple substrate openings 111 simultaneously to ensure airflow volume. Furthermore, the substrate openings 111 themselves are connected to multiple strands of coil 121. The multiple substrate openings 111 are densely arranged to form a structure such as... Figure 2 The structure of the dense coil 121 and the substrate opening 111 is shown. The multi-strand coils 121 are all disposed on the substrate layer 110 and are arranged sequentially along the outline of the substrate opening 111. That is, the multi-strand coils 121 are all disposed at the edge of the substrate opening 111. The multi-strand coils 121 can retain (or can be understood as absorb, support, and retain) a large amount of moisture on themselves after the liquid holding element 100 is wetted, and realize the evaporation of moisture when the airflow blows, so as to increase the humidity of the airflow and thus realize the air humidification function.

[0053] Specifically, since the coil 121 is located at the edge of the substrate opening 111, it has less resistance to the airflow blowing through the multiple substrate openings 111, which can reduce air infiltration resistance, enhance ventilation effect, and increase air volume. Furthermore, since the multiple coils 121 are arranged sequentially along the contour extension direction of the substrate opening 111 and are dispersed, their contact area with the airflow is larger, which can increase the contact area with the air, improve humidification efficiency, and ensure humidification effect.

[0054] In this embodiment, refer to Figure 3 The coil 121 is arranged in a ring, meaning that both the braiding start 123 and the braiding end 124 of the coil 121 are connected to the opening sidewall of the substrate opening 111. The ring-shaped coil 121 and the substrate layer 110 cooperate to form a dense three-dimensional structure (e.g., Figure 4 and Figure 5The physical diagram visually demonstrates the actual structural effect of the substrate layer 110 and the liquid holding part 120, further increasing the contact area with air, improving humidification efficiency, and enhancing the uniformity of moisture evaporation into the airflow, thereby achieving uniform humidification. Specifically, the annular coil 121 design, compared to non-annular wire harnesses, allows the coils to surround the moisture, making it easier for the moisture to be held within each ring, allowing the moisture to be retained for a longer and greater amount, thus increasing the effective humidification time. The regular weaving of the annular coils 121 on the substrate layer 110 improves the spatial distribution density and uniformity of the coils 121, and enables stable airflow through the liquid holding element 100, reducing airflow loss.

[0055] In this embodiment, the coil 121 is arranged in a ring, with adjacent coils 121 interlocked. That is, the multiple coils 121 arranged sequentially are interlocked, which can further increase the spatial distribution density of the coil 121, allowing the coil 121 to absorb more moisture, thereby increasing the amount of moisture evaporation, improving humidification efficiency, and enhancing the humidification effect. At the same time, it can also enhance the stability of the coil 121, reduce the occurrence of coil 121 scattering, thereby extending the service life of the liquid holding element 100, ensuring the humidification effect, and improving the user experience.

[0056] The structural relationship between the multiple coils 121 will be explained below, with three examples provided for illustration.

[0057] (First embodiment)

[0058] refer to Figure 2 and Figure 3 In this embodiment, the coil 121 is woven onto the substrate layer 110. Specifically, the substrate layer 110 itself is densely provided with a plurality of weaving gaps (not shown). The weaving gaps are formed by, for example, the yarn of the substrate layer 110, i.e., the weaving yarns interweave to form the weaving gaps, and the weaving start end 123 and the weaving end end 124 of the coil 121 both pass through the weaving gaps.

[0059] It should be noted that in different braiding processes, the braiding start 123 and braiding end 124 of coil 121 can both pass through the same braiding gap, or they can pass through different braiding gaps respectively. This utility model does not make any specific limitation.

[0060] In addition, in different weaving processes, the coil 121 can be formed by separating the yarn from the substrate layer 110 (that is, at least a part of the yarn extends outward to form the coil 121), or it can be an independent coil 121 connected or wound on the substrate layer 110. This utility model does not make specific limitations.

[0061] In this embodiment, combined with Figure 4 and Figure 5 As shown, the substrate layer 110 is a single-sided fabric, and the multi-strand coils 121 are all disposed on the same side of the substrate layer 110, that is, the multi-strand coils 121 extend outward from the same side of the substrate layer 110. However, it is not limited to this. In other embodiments, the substrate layer 110 is a double-sided fabric, and the multi-strand coils 121 are disposed on both sides of the substrate layer 110, that is, the multi-strand coils 121 extend outward from both sides of the substrate layer 110.

[0062] Preferably, the coil 121 protrudes from the surface of the substrate layer 110 in the thickness direction, and the protrusion height is less than 30mm. Specifically, by protruding from the surface of the substrate layer 110, the coil 121 can effectively increase the contact area between the coil 121 and the air, thereby increasing the evaporation efficiency of moisture inside the coil 121, improving humidification efficiency, and enhancing the humidification effect. Furthermore, by appropriately setting the protrusion height of the coil 121, its obstruction of air can be minimized while ensuring humidification efficiency, reducing air permeability resistance, enhancing ventilation, and increasing airflow.

[0063] Preferably, the coil 121 comprises multiple yarns (not shown), that is, multiple smaller yarns are combined to form the coil 121. The multiple yarns can be arranged in parallel or entangled, with gaps between the yarns, which has a good moisture retention or carrying effect, that is, it gives the coil 121 a good water absorption effect. Therefore, the multiple yarns work together to further enhance the water absorption effect, thereby increasing the contact between moisture and air, increasing the evaporation rate, and thus improving the humidification efficiency.

[0064] Preferably, the number of yarns is 5-15. A reasonable number of yarns can minimize the obstruction of air while ensuring humidification efficiency, reduce air permeability resistance, enhance ventilation, and increase air volume. Specifically, too few yarns are not conducive to moisture carrying capacity and affect the humidification effect, while too many yarns are not conducive to air passage efficiency and affect the ventilation effect.

[0065] In this embodiment, both the yarn and the thread are made of polyester. The thread has a higher stiffness than the yarn, so that the substrate layer 110 of the liquid holding element 100 has a certain degree of stiffness, facilitating installation and disassembly. The yarn has a higher water absorption capacity than the thread, so that the coil 121 has better water absorption, improving humidification efficiency. However, this is not the only embodiment. In other embodiments, the yarn and thread may also contain materials such as nylon or spandex to achieve a certain degree of stiffness or elasticity. The materials of the yarn and thread can also be different, and there is no specific limitation on the materials of the yarn and thread.

[0066] In this embodiment, the substrate opening 111 is hexagonal, that is, the multi-strand coils 121 are arranged sequentially along the outline of the hexagonal shape of the substrate opening 111, and the airflow can pass through the interior of the hexagonal shape of the substrate opening 111. However, it is not limited to this. In other embodiments, the substrate opening 111 can be rhomboid or elliptical, and the shape of the substrate opening 111 is not specifically limited.

[0067] (Second Embodiment)

[0068] Please refer to Figure 6 , Figure 6 This is a partially enlarged structural schematic diagram of the liquid holding element 100 provided in the second embodiment of this utility model. This embodiment of the utility model provides a carrier 100, which differs from the first embodiment in the arrangement of the coil 121.

[0069] In this embodiment, the coils 121 are arranged in a ring shape, closer to a perfect circle. Adjacent coils 121 are interlocked, and any two coils 121 located on opposite sides of the substrate opening 111 and corresponding in position are interlocked. For example, the coil 121 located on the upper side of the substrate opening 111 is interlocked with the coil 121 located on the lower side of the substrate opening 111. This arrangement results in more coils 121 facing the substrate opening 111 compared to the first embodiment (i.e., the area of ​​the coils 121 projected onto the plane of the substrate opening 111 is larger than in the first embodiment), further increasing the spatial distribution density of the coils 121. This allows the coils 121 to absorb more moisture, and also allows more air flowing through the substrate opening 111 to contact the coils 121, thereby increasing the evaporation of moisture, improving humidification efficiency, and enhancing the humidification effect.

[0070] However, compared to the design of the first embodiment, the air circulation efficiency of this embodiment is relatively reduced. Designers in the art should weigh the trade-offs between air circulation efficiency and humidification efficiency.

[0071] The beneficial effects of the liquid holding element 100 provided in this embodiment are the same as those in the first embodiment, and will not be repeated here.

[0072] (Third embodiment)

[0073] Please refer to Figure 7 , Figure 7 This is a partially enlarged structural schematic diagram of the liquid holding element 100 provided in the third embodiment of this utility model. This embodiment of the utility model provides a carrier 100, which differs from the first embodiment in the arrangement of the coil 121.

[0074] In this embodiment, the coil 121 is arranged in a ring, and the multiple coils 121 are arranged independently, that is, adjacent coils 121 are no longer interlocked. This reduces the spatial distribution density of the coils 121, thereby further reducing air permeation resistance, enhancing ventilation, and increasing air volume. Moreover, compared with the first embodiment, the design of this embodiment, with the multiple coils 121 being independent, makes it less likely for them to tangle together. This makes it easier to bend and fold the liquid holding element 100 to a greater extent, improving the versatility of the liquid holding element 100.

[0075] However, compared to the design of the first embodiment, the air humidification efficiency of this embodiment is relatively reduced. Designers in the art should weigh the trade-offs between air circulation efficiency and humidification efficiency.

[0076] The beneficial effects of the liquid holding element 100 provided in this embodiment are the same as those in the first embodiment, and will not be repeated here.

[0077] It should be noted that the above three embodiments can be implemented simultaneously on the same liquid holding element 100, or only one or two embodiments can exist on a single liquid holding element 100; there is no limitation in this regard.

[0078] The above is a partial description of the structure of the liquid holding element 100, specifically the coil 121 of the substrate layer 110 and the liquid holding part 120.

[0079] The overall structure of the liquid holding element 100 will now be described.

[0080] Please refer to the reference first. Figure 8 and Figure 9 , Figure 9 This is a cross-sectional schematic diagram of the liquid holding element provided by this utility model. The overall shape of the liquid holding element 100 is cylindrical, that is, ventilation openings 140 are provided at opposite ends, and a closed, surrounding cylindrical wall is located between the two ventilation openings 140. The liquid holding element 100 includes a substrate layer 110 and a liquid holding part 120. As described above, the liquid holding part 120 is composed of multiple coils 121, and in this embodiment, the liquid holding part 120 is connected to the substrate layer 110 to prevent the multiple coils 121 of the liquid holding part 120 from falling off, thereby improving durability and convenience.

[0081] Specifically, such as Figure 8As shown, the substrate layer 110 includes an outer substrate layer 1107 and an inner substrate layer 1108. With the central axis of the cylindrical liquid holding element 100 as a reference, the outer substrate layer 1107 is located on the side relatively away from the central axis of the liquid holding element 100, and the inner substrate layer 1108 is located on the side relatively close to the central axis of the liquid holding element 100, that is, the outer substrate layer 1107 is farther away from the central axis of the liquid holding element 100 than the inner substrate layer 1108.

[0082] As described above, both the outer substrate layer 1107 and the inner substrate layer 1108 are provided with substrate openings 111.

[0083] like Figure 9 As shown, a liquid holding portion 120 is provided between the outer substrate layer 1107 and the inner substrate layer 1108. The liquid holding portion 120 includes an outer liquid holding portion 1204 and an inner liquid holding portion 1205. The outer liquid holding portion 1204 is connected to the outer substrate layer 1107 and is located on the side closer to the central axis of the liquid holding element 100 relative to the outer substrate layer 1107; the inner liquid holding portion 1205 is connected to the inner substrate layer 1108 and is located on the side farther from the central axis of the liquid holding element 100 relative to the inner substrate layer 1108. That is, the inner liquid holding portion 1205 is closer to the central axis of the liquid holding element 100 than the outer liquid holding portion 1204.

[0084] In other words, from the radial direction gradually approaching the central axis of the liquid holding element 100, the following are arranged sequentially: outer substrate layer 1107, outer liquid holding portion 1204, inner liquid holding portion 1205, and inner substrate layer 1108. It can be roughly understood that the main structure of the liquid holding element 100 is roughly such that the substrate layer 110 wraps around the liquid holding portion 120, that is, the liquid holding portion 120 is not exposed on the outside of the substrate layer 110.

[0085] With this design, during air humidification, when air is guided to the liquid holding element 100, it typically passes from the outer periphery of the liquid holding element 100 itself, then enters the inner side of the liquid holding element 100 (i.e., the side closer to the central axis), and is then discharged through the ventilation openings 140 at both ends or one end of the liquid holding element 100. In other words, the air first contacts the outer substrate layer 1107, then the outer liquid holding section 1204, then the inner liquid holding section 1205, and finally exits the liquid holding element 100 after passing through the inner substrate layer 1108. Therefore, the air passes through the liquid holding section 120 twice, thereby further increasing the contact opportunity between moisture and air, increasing evaporation, and thus improving humidification efficiency.

[0086] On the other hand, the substrate layer 110 covers the liquid holding part 120, that is, the liquid holding part 120 is not exposed on the outside. In terms of appearance, the grid-like substrate layer 110 covers the liquid holding part 120 of multiple densely arranged coils, that is, the messy coils are not exposed, making the liquid holding element 100 more aesthetically pleasing overall, while reducing the possibility of the liquid holding part 120 being damaged by the outside and improving its durability.

[0087] The design of the upper and lower ends of the liquid holding element 100 will be described in detail below. This application will illustrate three variations of the end shape of the liquid holding element 100.

[0088] (Variation Example 1)

[0089] refer to Figure 8 and Figure 10 , Figure 10 Therefore Figure 9 The diagram shows a modified example 1 of the enlarged structure of plane A. The liquid holding element 100 has edge-wrapping portions 400 at its upper and lower ends. These edge-wrapping portions 400 wrap around and cover the edges of the outer substrate layer 1107 and the inner substrate layer 1108 located at both ends of the liquid holding element 100, thereby connecting and fixing the outer substrate layer 1107 and the inner substrate layer 1108 together, thus forming a single integral structure for the liquid holding element 100. Furthermore, the edges of the outer substrate layer 1107 and the inner substrate layer 1108 of the mesh form a burr-like shape, which could easily cause injury or inconvenience to the user. Therefore, covering these edges with edge-wrapping portions 400 improves ease of use and user experience.

[0090] refer to Figure 10 There are two edging portions 400, located at the upper and lower ends of the liquid holding element 100 respectively. The cross-section of the edging portion 400 forms an arc-like shape. When viewed as a whole from the liquid holding element 100, the edging portion 400 is a ring-shaped structure with its ends connected (see reference). Figure 8 (As shown). The edging portion 400 is provided with a plurality of arranged edging through holes 401, which are used to allow air to pass through and enter the liquid holding portion 120 or to exit from the liquid holding portion 120. The edging portion 400 may be, for example, a cloth, a mesh fabric, or the same structural material as the substrate layer 110.

[0091] In addition, the edge portion 400 may be further provided with a coil structure (not shown) identical to that of the liquid holding portion 120 to further improve the moisture absorption capacity. Preferably, the coil structure identical to that of the liquid holding portion 120 provided on the edge portion 400 is provided on the side facing the liquid holding portion 120 to ensure that the liquid holding element 100 as a whole has no exposed coil, improves the aesthetics, reduces the possibility of the liquid holding portion 120 being damaged by external factors, and improves the durability of use.

[0092] The edge binding portion 400 connects the edges of the outer substrate layer 1107 and the inner substrate layer 1108 via the joint portion 130. In this modified example, there are four joint portions 130, with two joint portions 130 at each of the upper and lower ends. The joint portion 130 can be a sewing thread, ultrasonic quilting, heat pressing, adhesive thread, or other connection method, which is not limited here. Since the liquid holding element 100 is cylindrical, each joint portion 130 is provided along the circumference of the cylindrical shape, ultimately forming a continuous or discontinuous ring shape.

[0093] (Variation Example 2)

[0094] refer to Figure 11 This is the implementation method of Modification Example 2. Compared with Modification Example 1, which uses a combination of two substrate layers 110 and two edge-wrapping portions 400, Modification Example 2 does not require edge-wrapping portions 400 and only requires one substrate layer 110 for winding, which will be explained in detail below.

[0095] Please refer to Figures 11 to 13 , Figure 12 and Figure 13 In variation 2, the liquid holding element 100 is not in its final state (i.e., Figure 11 The previous state of the structure shown can be understood as a flat state. Figure 12 This refers to the flat state of the liquid holding element 100 facing the side of the substrate layer 110. Figure 13 This refers to the flat state of the liquid holding element 100 facing the side of the liquid holding section 120, i.e. Figure 12 and Figure 13 These are opposite side views of the liquid holding element 100 in its flat state.

[0096] Please refer to Figure 11 In this modified example, the final state of the liquid holding element 100 is determined by, as follows: Figure 12 The liquid holding element 100 in this modified example is formed by folding a single flat structure, as shown in the diagram. The structure of the flat liquid holding element 100 is the same as that of the partial liquid holding element 100 described above, so it will not be described again. Please refer to the description above.

[0097] The following explains how the liquid holding element 100 in its flat state forms the final state of the liquid holding element 100 in this modified example.

[0098] The flat liquid holding element 100 is a rectangular sheet. On the substrate layer 110, the two ends parallel to the axial direction of the final cylindrical liquid holding element 100 are the substrate axial end 1101 and the substrate axial other end 1102. The two ends perpendicular to the axial direction of the final cylindrical liquid holding element 100 are the substrate circumferential end 1103 and the substrate circumferential other end 1104.

[0099] First, such as Figure 12 As shown by the folding direction arrow, the circumferential end 1103 of the substrate is bent along the folding position A, and bent in the direction opposite to the liquid holding parts 120 (i.e., with...). Figure 12 Similarly, the substrate circumferential end 1104 is bent along the fold line at fold position B, and bent in the direction opposite to the liquid holding parts 120 (i.e., with...). Figure 12 (Bend the side away from the reader). Among them, fold position A is located at 1 / 4 of the length of the substrate axial end 1101 (or the other end 1102 of the substrate axial direction), and fold position B is located at 3 / 4 of the length of the substrate axial end 1101 (or the other end 1102 of the substrate axial direction), and so on.

[0100] Similarly, Figure 13 Showing with Figure 12 The bending method from the opposite perspective is the same as the principle described above, and will not be repeated here.

[0101] After bending, connect and fix one circumferential end 1103 of the substrate to the other circumferential end 1104 of the substrate (fixed through the joint 130). Then, maintaining the axial direction of the final cylindrical shape of the liquid retaining element 100, bend and connect one axial end 1101 of the substrate and the other axial end 1102 of the substrate, and fix them to obtain the desired result. Figure 11 The final cylindrical shape of the liquid holding element 100 shown.

[0102] The joint 130 can be a sewing thread, ultrasonic quilting, heat pressing, adhesive thread, or other connection method, which is not limited here. Since the liquid holding element 100 is cylindrical, the joint 130 is provided along the circumference of the cylindrical shape, ultimately forming a continuous or discontinuous ring shape.

[0103] Therefore, in this modified example, it can be understood that the outer substrate layer 1107 and the inner substrate layer 1108 are connected to each other at both ends of the cylindrical liquid holding element 100.

[0104] Compared to Modified Example 1, this modified example does not require the additional edge-sealing part 400, i.e., it does not require the edge-sealing operation. At the same time, the upper and lower ends of the liquid holding element 100 are also provided with coils (liquid holding part 120), which saves materials and has a relatively better humidification effect, but requires an additional winding production process.

[0105] (Variation Example 3)

[0106] Please refer to Figure 14This is a specific form of variation 3. Simply put, in this variation, the edges of the two substrate layers 110 (i.e., the outer substrate layer 1107 and the inner substrate layer 1108) are directly connected together via the joint 130 to achieve fixation. The joint 130 can be a sewing thread, ultrasonic stitching, heat pressing, adhesive thread, or other connection method, and is not limited here. Since the liquid holding element 100 is cylindrical, the joint 130 is provided along the circumference of the cylinder, ultimately forming a continuous or discontinuous ring shape.

[0107] Compared with Modified Example 1 and Modified Example 2, the implementation process of Modified Example 3 is the simplest, but attention needs to be paid to the treatment of the upper and lower edges. For example, it can be sewn with a sewing thread of a certain width to cover the edge of the substrate layer 110 and avoid burrs being exposed.

[0108] Now, let's go back to... Figure 8 In this embodiment, the liquid holding element 100 also includes a handle 300. Two handles 300 are provided, located on opposite sides of the liquid holding element 100, specifically on both sides of the upper end of the liquid holding element 100. The handles 300 are annular straps and are respectively connected and fixed to the substrate layer 110. By providing the handles 300, users can easily lift the entire liquid holding element 100 without getting their hands wet from the liquid holding portion 120, facilitating the installation and removal of the liquid holding element 100 and improving the user experience.

[0109] The above is a detailed explanation of the structure and function of the liquid holding element 100.

[0110] Below, we will provide a brief explanation of the air humidification device.

[0111] The air humidifier (not shown) includes a liquid holding element 100, a water storage module (not shown), and / or a water spraying module (not shown). The water storage module and the water spraying module can be installed simultaneously in the air humidifier, or only one of them may be installed, depending on different design requirements.

[0112] The water spraying module is used to evenly distribute externally supplied moisture onto the liquid holding element 100. Typically, the water spraying module is located above the liquid holding element 100 and has multiple water spraying openings facing the substrate layer 110, allowing moisture to be directly delivered to the corresponding substrate layer 110 through the water spraying openings. Then, through the substrate openings 111 on the substrate layer 110, the moisture enters the liquid holding part 120, where it is absorbed and retained by the coils 121. Furthermore, the multiple coils 121 can diffuse and transport moisture, wetting the entire liquid holding element 100 and achieving the air humidification function.

[0113] The water storage module is used to store externally supplied water or collect water supplied from the water spraying module. Typically, the water storage module is shaped like a tray or tank, with a liquid holding element 100 placed on top of it or within the water storage space. This allows the water storage module to receive water falling from the liquid holding element 100 or for the liquid holding element 100 to reabsorb water collected by the water storage module. Furthermore, the water storage module allows the user to easily empty the collected and stored water.

[0114] The water spraying module and the water storage module can be designed in various forms according to the designer's needs, which will not be described in detail in this utility model.

[0115] In addition, in order to make the liquid holding element 100 more stable in the air humidification device, a support structure can be provided inside the liquid holding element 100. The support structure can be, for example, a cylindrical structure that supports the inside of the liquid holding element 100. Designers in the art can adjust the support structure according to various needs, so it will not be discussed here.

[0116] In addition, preferably, the substrate layer 110 is made of an elastic material. For example, adding elastic fibers such as spandex to the material of the substrate layer can make the substrate layer 110 have elastic properties. In this way, the liquid holding element 100 can be easily fitted and fixed on the corresponding support structure or air humidification device, improving the ease of installation and disassembly.

[0117] When the user needs to clean and maintain the liquid holding element 100, simply pull the handle 300 to lift the entire liquid holding element 100 and detach it from the device. Then, rub the liquid holding element 100 with water to clean it, removing substances such as scale and impurities. It can then be reinstalled on the air humidifier for reuse.

[0118] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
