Description

Technical Field

[0001] The present application relates to the field of air purification, and in particular to an air purification device and a filtering device. Background Art

[0002] As people's living standards improve, more and more families are beginning to use air purification equipment to purify the air in order to improve their quality of life.

[0003] At present, when an air purification device purifies the air, the dirt adsorbed by the air purification device will mostly be concentrated on the position corresponding to the purification hole on the filter element. The filter element cannot be fully utilized, affecting the service life of the filter element and unnecessary waste of resources. In addition, the dirt is easy to concentrate and clog the purification holes, causing blockage of the air duct, resulting in reduced energy efficiency of the air purification device. Summary of the invention

[0004] The purpose of the present application is to provide an air purification device and a filtering device, which can distribute adsorbed dirt on the filter element, alleviate air duct blockage, and improve the energy efficiency of the air purification device.

[0005] To achieve the above-mentioned objectives, the present application provides an air purification device on the one hand, which at least includes a filter device and a fan component; the filter device includes a filter element assembly and a shell assembly, and the filter element assembly is constructed as a barrel-shaped structure with an open top; the shell assembly is sleeved on the outer wall of the filter element assembly, and a storage cavity is formed between the inner wall of the shell assembly and the outer wall of the filter element assembly. A purification hole is opened on the outer wall of the shell assembly, and the purification hole includes at least a first hole structure, which is arranged around the axis of the shell assembly and close to the bottom of the shell assembly; the air inlet of the fan component is connected to the opening, and when the fan component is running, the air in the external environment passes through the purification hole, the storage cavity and the filter element assembly in turn to enter the interior of the filter element assembly, and is discharged to the external environment through the fan component.

[0006] To achieve the above-mentioned purpose, the present application further provides an air purification device on the other hand, which includes a body, a first filter element and a fan component; the body has a accommodating cavity, and a first hole structure is opened on the side wall of the body, the first hole structure is arranged around the accommodating cavity, the first hole structure is connected to the accommodating cavity, and the first hole structure is close to the bottom of the accommodating cavity; the first filter element is connected to the body, and a storage cavity is formed between the first filter element and the inner wall of the accommodating cavity, the first filter element extends from the bottom of the accommodating cavity to the top of the accommodating cavity, and the orthographic projection of the first hole structure on the first filter element is located on the first filter element; the air inlet of the fan component is connected to the top of the accommodating cavity, and when the fan component is in operation, the air in the external environment passes through the first hole structure, the storage cavity and the first filter element in sequence into the accommodating cavity, and is discharged to the external environment through the fan component.

[0007] To achieve the above-mentioned purpose, the present application further provides a filtering device on the other hand, which comprises at least a filter element assembly and a shell assembly; the filter element assembly is constructed as a barrel-shaped structure with an open top, and the open top is used to communicate with the air inlet of a fan component; the shell assembly is sleeved on the outer wall of the filter element assembly, and a storage cavity is formed between the inner wall of the shell assembly and the outer wall of the filter element assembly, and a purification hole is opened on the outer wall of the shell assembly, and the purification hole comprises at least a first hole structure, which is arranged around the axis of the shell assembly and close to the bottom of the shell assembly; when the fan component is running, the air in the external environment passes through the purification hole, the storage cavity and the filter element assembly in turn to enter the interior of the filter element assembly, and is discharged to the external environment through the fan component.

[0008] It can be seen that the technical solution provided by the present application is that a housing assembly is sleeved on the outer wall of the filter element assembly, and a first hole structure is opened on the housing assembly, the first hole structure surrounds the axis of the housing assembly and is located at the bottom of the housing assembly. In other words, the first hole structure is close to the bottom of the filter element assembly, and the air inlet of the fan component is connected to the top opening of the filter element assembly. In this way, when the fan component is running, the wind speed on the filter element assembly increases from the first hole structure upward in sequence, which makes it possible for part of the air in the external environment to enter the storage cavity through the first hole structure, and part of the air is directly filtered by the part of the filter element assembly corresponding to the first hole structure, and the other part of the air will flow upward under the action of the wind speed difference and be filtered by the rest of the filter element assembly, so that the air is distributed more evenly through the filter element assembly, increasing the area of ​​the filter element assembly involved in the filtration, thereby making full use of the filter element assembly and avoiding unnecessary waste of resources of the filter element assembly. At the same time, since the above structure only needs to set the first hole structure to make full use of the filter element assembly, compared with the existing purification hole that needs to cover the outer surface of the filter element assembly to make full use of the filter element assembly, the present application can reduce the number of openings on the housing assembly, thereby reducing production costs.

[0009] Furthermore, as the air passes through the filter element assembly in a relatively even distribution, the dirt carried in the air will also be relatively evenly distributed on the filter element assembly, thereby reducing the possibility of dirt being concentrated and accumulated on the portion of the filter element assembly corresponding to the first hole structure, causing blockage of the air duct, and improving the energy efficiency of the air purification device. In addition, even if the dirt is concentrated and accumulated on the portion of the filter element assembly corresponding to the first hole structure, causing blockage of the air duct, the blocked dirt will also be subjected to an upward thrust under the effect of the upper and lower wind speed differences of the filter element assembly, thereby pushing the dirt upward to the upper portion of the filter element assembly, thereby clearing the blockage and further reducing the possibility of blockage of the air duct.

[0024] To make the purpose, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings. Terms such as "upper", "above", "lower", "below", "first end", "second end", "one end", "the other end" used in the present application to represent spatial relative positions are used to describe the relationship between a unit or feature as shown in the accompanying drawings relative to another unit or feature for the purpose of convenience of explanation. Terms of spatial relative position may be intended to include different orientations of the device in use or work other than the orientation shown in the figure. For example, if the device in the figure is turned over, the unit described as being "below" or "below" other units or features will be located "above" other units or features. Therefore, the exemplary term "below" can encompass both the above and below orientations. The device can be oriented in other ways (rotated 90 degrees or other orientations), and the spatially related descriptors used herein are interpreted accordingly.

[0025] In addition, the terms "installed", "set", "provided with", "connected", "slidingly connected", "fixed", and "sleeved" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0026] As people's living standards improve, more and more families begin to use air purification equipment to purify the air to improve the quality of life. At present, the air inlet of the fan component in the air purification device is roughly on the same horizontal line as the filter element. When the air purification device purifies the air, the suction force of the fan component on the filter element corresponding to its air inlet is almost the same, so that most of the dirt adsorbed by the air purification device will be concentrated on the position corresponding to the purification hole on the filter element, and the part of the filter element that does not correspond to the purification hole will not participate in air filtration. Obviously, the purification hole in the existing air purification device needs to cover the filter element in order to fully utilize the filter element, which also leads to an increase in the number of openings of the air purification device and an increase in manufacturing costs. Otherwise, the filter element cannot be fully utilized, and it will also cause unnecessary waste of resources for the filter element. In the long run, the dirt on the filter element will continue to accumulate on the position corresponding to the purification hole on the filter element, aggravating the loss of the filter element, and causing the air duct to be blocked, so that the air purification device requires more energy to promote the circulation and filtration of the air, increasing energy consumption and operating costs, and resulting in reduced energy efficiency of the air purification device.

[0027] Furthermore, most of the existing air purification devices are fixed devices, and are limited by their suction power. Therefore, they can only purify the air in a fixed surrounding area, and cannot actively purify the air in other areas. The air purification range is limited and the purification effect is poor. In addition, the purification holes of the existing air purification devices are small, which causes some long hairs in the air to be unable to be smoothly sucked into the interior of the air purification device, and are blocked outside the purification holes. This not only affects the aesthetics of the air purification device and reduces the user experience, but also fails to purify the floating hairs in the air, resulting in poor purification effect.

[0028] In addition, due to the limited service life of the filter element, in order to ensure the air purification effect, users need to replace the filter element regularly, and the existing filter element replacement cost is relatively high, which increases the user's usage cost and increases the user's usage burden.

[0029] Therefore, how to improve the structure of the air purification equipment to distribute the adsorbed dirt on the filter element, alleviate the blockage of the air duct, and improve the energy efficiency of the air purification equipment has become a problem that needs to be solved urgently in this field.

[0030] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the embodiments described in this application are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0031] Please also see Figures 1 to 4 In one feasible implementation, the air purification device is used to purify the air in the area where it is located to improve the air quality. Among them, the air purification device may include at least a filter device 100 and a fan component 200. The fan component 200 is used to form a directional airflow in the air through high-speed rotating blades, and to allow the directional airflow to pass through the filter device 100. In this way, the air in the external environment can flow through the filter device 100, and the filter device 100 will filter the air and then discharge it into the external environment, and the cycle will continue, thereby purifying the air in the external environment. It should be pointed out that the air purification device can be a fixed air purification device, a portable air purification device, or a self-moving cleaning device that can move automatically along a pre-planned path according to the control instructions in the host, etc., which is not specifically limited here.

[0032] In this embodiment, the filter device 100 may include a filter element assembly 110 and a housing assembly 120. The filter element assembly 110 may be constructed as a barrel-shaped structure with an opening 111 at the top, and the filter element assembly 110 filters the air through the side wall portion. The side wall of the filter element assembly 110 has an inner wall and an outer wall, the housing assembly 120 is sleeved on the outer wall of the filter element assembly 110, and a purification hole 130 is opened on the outer wall of the housing assembly 120, and the housing assembly 120 restricts the air in the external environment from entering the housing assembly 120 through the purification hole 130 and contacting the filter element assembly 110, and the housing assembly 120 can also protect the filter element assembly 110 to prevent the filter element assembly 110 from collision damage.

[0033] In an achievable embodiment, the purification hole 130 may at least include a first hole structure 131, which is arranged around the axis of the housing assembly 120 and close to the bottom of the housing assembly 120, and a storage cavity 140 is also provided between the inner wall of the housing assembly 120 and the outer wall of the filter element assembly 110. In this way, when the air in the external environment enters the housing assembly 120 through the first hole structure 131, the dirt in the air is blocked by the filter element assembly 110, and is thus retained in the storage cavity 140 for dirt storage. Among them, the air inlet of the fan component 200 should be connected to the opening 111. When the fan component 200 is running, the fan component 200 can form a negative pressure inside the filter element assembly 110. Under the action of the negative pressure, the air in the external environment passes through the purification hole 130, the storage cavity 140 and the filter element assembly 110 in sequence to enter the interior of the filter element assembly 110, and is discharged to the external environment through the fan component 200.

[0034] It is worth mentioning that in the above structure, the air inlet of the fan component 200 is connected to the top opening 111 of the filter element assembly 110, and the first hole structure 131 is located at the bottom of the housing assembly 120, that is, the first hole structure 131 is close to the bottom of the filter element assembly 110. In other words, the connection between the air inlet of the fan component 200 and the filter element assembly 110 and the first hole structure 131 are located at both ends of the filter element assembly 110. It can be understood that since the fan component 200 generates centrifugal force through the high-speed rotation of the blades to suck air into the air inlet of the fan component 200, the closer the position is to the air inlet of the fan component 200, the higher the air flow speed and the wind speed is relatively large. In other words, the wind speed of the filter element assembly 110 increases from the first hole structure 131 upward. This means that when the air in the external environment enters the storage cavity 140 through the first hole structure 131, part of the air is directly filtered by the part of the filter element assembly 110 corresponding to the first hole structure 131, and the other part of the air can flow upward under the effect of the wind speed difference and be filtered by the rest of the filter element assembly 110, so that the air is distributed more evenly through the filter element assembly 110, increasing the area of ​​the filter element assembly 110 involved in the filtration, and avoiding unnecessary waste of resources of the filter element assembly 110. In addition, as the air is distributed more evenly through the filter element assembly 110, the dirt carried in the air will also be more evenly distributed on the filter element assembly 110, thereby reducing the possibility of dirt accumulating on the part of the filter element assembly 110 corresponding to the first hole structure 131 and causing air duct blockage, thereby improving the energy efficiency of the air purification equipment.

[0035] In addition, even if the dirt is concentrated on the part of the filter element assembly 110 corresponding to the first hole structure 131 and causes the air duct to be blocked, the blocked dirt will also be pushed upward under the effect of the wind speed difference between the upper and lower parts of the filter element assembly 110, thereby pushing the dirt upward to the upper part of the filter element assembly 110, thereby clearing the blockage and further reducing the possibility of blockage in the air duct. At the same time, since the above structure only needs to set the first hole structure 131 surrounding the axis of the shell assembly 120 to fully utilize the filter element assembly 110, compared with the existing purification hole 130 that needs to cover the outer surface of the filter element assembly 110 to fully utilize the filter element assembly 110, the present application can also reduce the number of openings on the shell assembly 120, thereby reducing production costs.

[0036] In practical applications, the first hole structure 131 can be perpendicular to the axis of the shell assembly 120. Of course, the first hole structure 131 can also form a certain angle with the axis of the shell assembly 120, but the angle should not be a right angle, and the angle should not be too large, otherwise it will cause a larger area of ​​the filter element assembly 110 to be located below the first hole structure 131 and unable to participate in the filtering work, affecting the purification effect of the air purification equipment and the service life of the filter element assembly 110. Considering that when the dirt blocked by the filter element assembly 110 falls off from the outer wall of the filter element assembly 110, the dirt is stored at the bottom of the storage cavity 140, therefore, a certain distance (such as 0.04mm) should be left between the first hole structure 131 and the bottom of the storage cavity 140. Figure 4 The distance d) shown is used to avoid the possibility that dirt stored at the bottom of the storage cavity 140 leaks out from the first hole structure 131.

[0037] Regarding the specific structure of the filter element assembly 110, in an achievable embodiment, the filter element assembly 110 may only include the first filter element 112, and the first filter element 112 is configured as a continuous annular structure, and the air is filtered by the first filter element 112. In this embodiment, the cross-section of the first filter element 112 may be elliptical, circular, rectangular, racetrack-shaped, etc., which is not specifically limited here.

[0038] In another possible implementation, Figure 4 and Figure 5As shown, the filter element assembly 110 may also include a bottom plate 113 and a top plate 114, wherein the bottom plate 113 is connected to the bottom of the first filter element 112, and the bottom plate 113 blocks the bottom opening of the first filter element 112 to reduce the air leakage generated by the bottom opening of the first filter element 112, thereby affecting the air flow rate passing through the first filter element 112. It should be noted that the bottom plate 113 can completely block the bottom opening of the first filter element 112. Of course, when the filter element assembly 110 needs to be assembled to the body 300 for use, the bottom plate 113 can also partially block the bottom opening of the first filter element 112, and the bottom plate 113 and the body 300 cooperate to completely block the bottom opening of the first filter element 112.

[0039] The top plate 114 is connected to the top of the first filter element 112, and the opening 111 is opened on the top plate 114, and the opening 111 is connected to the top opening of the first filter element 112. When the fan component 200 is running, the air inlet of the fan component 200 can be connected to the inside of the first filter 112 through the opening 111 on the top plate 114. The bottom plate 113 and the top plate 114 support the upper and lower ends of the first filter element 112, which can enhance the overall structural strength of the filter element assembly 110 and improve the service life of the filter element assembly 110 compared to using the first filter element 112 alone.

[0040] In this embodiment, the bottom surface of the top plate 114 and the top surface of the bottom plate 113 can be provided with an annular groove, the top end of the first filter element 112 can be plugged into the annular groove on the top plate 114, and the bottom end of the first filter element 112 can be plugged into the annular groove on the bottom plate 113, so as to assemble the overall structure of the filter element assembly 110. In this way, when the filter element assembly 110 needs to be replaced, the top plate 114 and the bottom plate 113 can be separated from the first filter element 112, and the first filter element 112 can be replaced separately, thereby reducing the user's use cost. The edge of the top plate 114 and the edge of the bottom plate 113 can also protrude outward from the edge of the first filter element 112, and an installation space can also be formed between the protruding portion of the top plate 114, the protruding portion of the bottom plate 113 and the outer wall of the first filter element 112 to accommodate the above-mentioned housing assembly 120. In this way, the housing assembly 120 may not protrude from the outer edge of the filter element assembly 110, thereby ensuring the overall aesthetics of the air purification device.

[0041] In practical applications, the first filter element 112 may be formed of origami blocks, which can block dirt in the filtered air (including but not limited to particulate matter PM2.5 in the air). The first filter element 112 may also include an activated carbon layer, which may be stacked with the origami blocks to absorb toxic gases in the air.

[0042] The air purification device may only include a filter device 100 and a fan component 200, and the filter device 100 and the fan component 200 are used together to perform air filtering. At this time, there is no obstruction on the outer wall of the first filter element 112, and the first hole structure 131 can surround the axis of the shell assembly 120 for a whole circle.

[0043] However, in order to improve the integrity and aesthetic appearance of the air purification equipment, the air purification equipment often also includes a body 300, and the filter device 100 and the fan component 200 need to be integrated in the body 300. At this time, due to the connection structure between the body 300 and the filter device 100, part of the body 300 will form a certain degree of obstruction on the outer wall of the first filter element 112. In other words, the obstructed part of the outer wall of the first filter element 112 cannot participate in the air filtration work. Therefore, the first hole structure 131 can also be partially arranged around the axis of the shell assembly 120.

[0044] Regarding the specific structure in which the first hole structure 131 is partially arranged around the axis of the shell assembly 120, in a feasible embodiment, the first filter element 112 may include a part participating in air filtration and a part not participating in air filtration, wherein the part not participating in air filtration is blocked by the body 300, and the part participating in air filtration is exposed from the outer wall of the body 300, and the first hole structure 131 is opened in the part participating in air filtration, so that the first hole structure 131 is partially arranged around the axis of the shell assembly 120.

[0045] Further, such as Figure 5 and Figure 6 As shown, the part participating in air filtration can be an arcuate portion 1121, and there is at least one arcuate portion 1121, so as to utilize the curved structure of the arcuate portion 1121 to increase the area of ​​the part participating in air filtration in a fixed space and improve the purification effect. The part not participating in air filtration is fitted with the housing assembly 120, that is, the remaining part of the outer wall of the first filter element 112 after removing the arcuate portion 1121 is fitted with the housing assembly 120, so that the remaining part of the first filter element 112 after removing the arcuate portion 1121 is blocked by the housing assembly 120. Correspondingly, the above-mentioned storage cavity 140 is formed between the outer wall of the arcuate portion 1121 and the inner wall of the housing assembly 120, so that the air entering the storage cavity 140 through the purification hole 130 enters the interior of the first filter element 112 only through the arcuate portion 1121. Among them, when there are multiple arcuate portions 1121, there should also be multiple purification holes 130, and the number of purification holes 130 should be the same as the number of arcuate portions 1121 and be arranged one by one. The first hole structure 131 extends from one end of the arc-shaped portion 1121 to the other end of the arc-shaped portion 1121 , so that the arc-shaped portion 1121 participates in the filtering action as much as possible, thereby fully utilizing the arc-shaped portion 1121 .

[0046] In this embodiment, if Figure 3 As shown, the purification hole 130 may also include a second hole structure 132 and a third hole structure 133, the second hole structure 132 extending upward from one end of the first hole structure 131, and the third hole structure 133 extending upward from the other end of the first hole structure 131. In this way, the air inlet area of ​​the purification hole 130 can be increased and the air purification effect can be improved. In addition, the second hole structure 132 and the third hole structure 133 are equivalent to being located at both ends of the arc portion 1121, respectively, and because the wind speed is greater closer to the middle of the arc portion 1121, under the effect of the wind speed difference between the middle and the two ends of the arc portion 1121, part of the air entering the storage cavity 140 through the second hole structure 132 and the third hole structure 133 can flow to the middle, thereby avoiding the blockage of the air duct at the second hole structure 132 and the third hole structure 133.

[0047] The number of the arc-shaped portions 1121 in the first filter element 112 may be two, three, four, etc., and the present application does not impose any specific limitation on this.

[0048] Take the example of two arc-shaped portions 1121. Figure 6 As shown, for the convenience of description, the two arc portions 1121 can be defined as the first arc portion 1122 and the second arc portion 1123 respectively. The first filter element 112 also includes a first horizontal portion 1124 and a second horizontal portion 1125, and the first arc portion 1122, the first horizontal portion 1123, the second arc portion 1124 and the second horizontal portion 1125 are connected end to end in sequence. In practical applications, the first arc portion 1122, the second arc portion 1123, the first horizontal portion 1124 and the second horizontal portion 1125 can be formed in one piece to ensure the sealing of the interconnected parts. Of course, the first arc portion 1122, the second arc portion 1123, the first horizontal portion 1124 and the second horizontal portion 1125 can also be formed separately and then spliced, and this application does not make specific restrictions on this.

[0049] Correspondingly, such as Figure 7 As shown, the housing assembly 120 may include a first housing segment 121, a second housing segment 122, a third housing segment 123, and a fourth housing segment 124 connected end to end in sequence. The first housing segment 121 and the third housing segment 123 are both arc-shaped structures, the first housing segment 121 and the first arc portion 1122 are arranged face to face, the third housing segment 123 and the second arc portion 1123 are arranged face to face, and the first housing segment 121 and the third housing segment 123 are both provided with a purification hole 130. The second housing segment 122 and the first horizontal portion 1124 are arranged face to face, and the fourth housing segment 124 and the second horizontal portion 1125 are arranged face to face.

[0050] In this embodiment, the distance between the second housing segment 122 and the fourth housing segment 124 should be equal to or slightly smaller than the distance between the outer wall of the first horizontal portion 1124 and the outer wall of the second horizontal portion 1125. When the housing assembly 120 is sleeved on the first filter element 112, the remaining portion of the first filter element 112 after removing the arc portion 1121 (i.e., the first horizontal portion 1124 and the second horizontal portion 1125) can fit with the housing assembly 120 to prevent the air entering the storage cavity 140 through the purification hole 130 from flowing to the first horizontal portion 1124 and the second horizontal portion 1125. Of course, the air entering the storage cavity 140 through the purification hole 130 can also be prevented from flowing to the first horizontal portion 1124 and the second horizontal portion 1125 by filling a sealant between the second housing segment 122 and the first horizontal portion 1124 and between the fourth housing segment 124 and the second horizontal portion 1125, and this application does not specifically limit this.

[0051] In practical applications, the first housing segment 121, the second housing segment 122, the third housing segment 123 and the fourth housing segment 124 can be integrally formed. Of course, in order to facilitate the disassembly and assembly of the housing assembly 120 and the filter element assembly 110, the first housing segment 121, the second housing segment 122, the third housing segment 123 and the fourth housing segment 124 can also be connected in a detachable manner, such as by snap connection, lock connection and screw connection.

[0052] Regarding the installation method of the filter device 100 and the body 300. In an achievable embodiment, for ease of understanding, the first filter element 112 in the filter device 100 has a first arc portion 1122, a second arc portion 1123, a first horizontal portion 1124 and a second horizontal portion 1125 as an example, please refer to Figure 1 , Figure 2 and Figure 8 As shown, the body 300 may have a housing cavity 310, an exposed port 320 and a mounting port 330. The housing cavity 310 is used to accommodate the filter device 100, and the exposed port 320 and the mounting port 330 are provided on the side wall of the body 300, and the exposed port 320 and the mounting port 330 are communicated with the housing cavity 310. When the filter device 100 enters the housing cavity 310 through the mounting port 330, the purification hole 130 on the first housing segment 121 is communicated with the external environment through the exposed port 320, and the purification hole 130 on the third housing segment 123 is communicated with the external environment through the mounting port 330. Among them, the fan component 200 can be installed on the top of the body 300, and the air inlet of the fan component 200 is communicated with the housing cavity 310. In this way, when the filter device 100 enters the accommodating cavity 310 through the installation opening 330 , the air inlet of the fan component 200 is located right above the opening 111 and the two are connected to each other.

[0053] In this practical application, the body 300 may include an upper body 340, a lower body 350 and two columns 360, the two columns 360 are supported between the upper body 340 and the lower body 350, and the two columns 360 are arranged at intervals, so as to form a receiving cavity 310, an exposed opening 320 and a mounting opening 330 on the body 300. When the filter device 100 enters the receiving cavity 310 through the mounting opening 330, the second shell segment 122 and the fourth shell segment 124 are respectively arranged corresponding to the two columns 360. It should be pointed out that since the two columns 360 only cover the second shell segment 122 and the fourth shell segment 124, and the first shell segment 121 and the second shell segment 123 are both convex arc structures, correspondingly, the purification holes 130 on the first shell segment 121 and the second shell segment 123 are also two convex arc structures. This means that when the air purification device is working, the air inlet surface formed by the purification holes 130 is close to a circle, that is, there is airflow intake in the air purification device in a direction of nearly 360°, thereby achieving all-round air purification without dead ends.

[0054] Furthermore, the bottom of the body 300 may be connected to a walking mechanism 370, which is used to drive the air purification device to move, thereby combining the mobile function of the body 300 with the air purification function, so that the air purification device is not limited to air purification in a single area, and the purification range of the air purification device is increased. For example, the user can set the air purification time of the air purification device in each area. When the air purification device reaches the preset purification time, the air purification device uses the walking mechanism 370 to move autonomously to another area to continue purification. Among them, the walking mechanism 370 may include but is not limited to a wheeled structure, a crawler structure, and a track structure.

[0055] The air purification efficiency and fixed-point purification range of the air purification device usually depend on the air flow rate at the purification hole 130, and the air flow rate at the purification hole 130 is related to the air inlet area of ​​the purification hole 130 and the power of the fan component 200. Therefore, during the design, the air inlet area of ​​the purification hole 130 and the power of the fan component 200 can be reasonably controlled to maximize the air flow rate at the purification hole 130 during operation. Among them, the air flow rate at the purification hole 130 should not be less than 2m / s, and preferably, the air flow rate at the purification hole 130 should be 2.5m / s.

[0056] Regarding the specific structure of the purification hole 130 , the present application provides two achievable embodiments for reference.

[0057] Example 1, please refer to Figure 3As shown, the first hole structure 131 , the second hole structure 132 and the third hole structure 133 may all be discontinuous hole structures, that is, the first hole structure 131 , the second hole structure 132 and the third hole structure 133 all include a plurality of ventilation holes 1311 .

[0058] In this embodiment, the plurality of ventilation holes 1311 are arranged at intervals, and the ventilation area of ​​each ventilation hole 1311 is not less than 4 cm 2 In this way, some longer dirt in the air (such as cat hair, dog hair and other pet hair) can be directly absorbed into the storage cavity 140 through the ventilation hole 1311, avoiding the longer dirt from being blocked outside the ventilation hole 1311, improving the purification effect of the air purification device, and ensuring the aesthetics of the air purification device. The shape of the ventilation hole 1311 can be rectangular, track-shaped, elliptical, etc., and this application does not make specific restrictions on this.

[0059] Embodiment 2, as Figures 9 to 11 As shown, the first hole structure 131 , the second hole structure 132 and the third hole structure 133 are all continuous hole structures. The second hole structure 132 is connected to one end of the first hole structure 131 , and the third hole structure 133 is connected to the other end of the first hole structure 131 .

[0060] In practical applications, such as Fig. 9 As shown, the first hole structure 131, the second hole structure 132 and the third hole structure 133 can be formed on the first shell segment 121 and the third shell segment 123 by directly opening holes. Fig.10 and Fig.11 As shown, larger rectangular holes 134 may also be respectively opened on the first shell segment 121 and the third shell segment 123, and then a forming plate 135 is connected to the top of each larger rectangular hole 134, and the forming plate 135 partially blocks the rectangular hole 134, so that the above-mentioned first hole structure 131, the second hole structure 132 and the third hole structure 133 are formed by the exposed parts of the rectangular holes 134.

[0061] In an achievable embodiment, the filter device may also include a shielding plate. The shielding plate is connected to the housing assembly 120, and the shielding plate is spaced apart from the outer wall of the housing assembly 120, and the orthographic projection of the shielding plate on the housing assembly 120 covers the purification hole 130, so that the air in the external environment passes through the gap between the shielding plate and the housing assembly 120, the purification hole 130, the storage cavity 140, and the first filter element 112 in sequence to enter the interior of the filter element assembly 110. The shielding plate can shield the purification hole 130, and at the same time shield the dirt that is blocked on the purification hole 130, thereby improving the user experience.

[0062] In practical applications, the shielding plate should be detachably connected to the shell assembly 120, so that when the purification hole 130 is clogged, the user can remove the shielding plate for cleaning, which facilitates the cleaning operation.

[0063] In one possible implementation, please refer again to Figure 4 and Figure 7 As shown, the filter device 100 also includes a hair suction piece 150, which is used to absorb floating hair. The hair suction piece 150 is detachably connected to the first filter element 112, and the hair suction piece 150 covers the outer wall of the arc portion 1121. Correspondingly, the storage cavity 140 is located between the hair suction piece 150 and the inner wall of the housing assembly 120. When the fan component 200 is running, the air in the external environment passes through the purification hole 130, the storage cavity 140, the hair suction piece 150 and the first filter element 112 in sequence to enter the interior of the filter element assembly 110. In other words, the air sucked into the purification hole 130 is first filtered by the hair suction piece 150, and then filtered by the first filter element 112, so that a large amount of floating hair is blocked by the hair suction piece 150 to improve the service life of the first filter element 112.

[0064] It should be noted that the hair suction piece 150 is usually made of a material with a high surface roughness such as polyester or viscose. Moreover, the hair suction piece 150 is relatively cheap compared to the first filter 112, and the hair suction piece 150 and the first filter 112 are detachably connected, so the user can replace the first filter 112 by regularly replacing the hair suction piece 150, thereby reducing the user's use cost. In addition, since the hair suction piece 150 has adsorption properties for floating hair, when cleaning the floating hair on the filter element device, the hair suction piece 150 can also reduce the possibility of the floating hair being inhaled by the human body.

[0065] In actual use, the filter device may further include a Velcro 160. The hair suction piece 150 is bonded to the first filter element 112 via the Velcro 160, thereby utilizing the bonding convenience of the Velcro 160 to improve the efficiency of disassembling and assembling the hair suction piece 150.

[0066] Based on the same inventive concept, the present application also provides an air purification device. Fig.12 and Fig.13As shown, the air purification device may include a body 300, a first filter element 112 and a fan component 200. The body 300 has a receiving cavity 310, and a first hole structure 131 is provided on the side wall of the body 300. The first hole structure 131 is arranged around the receiving cavity 310, the first hole structure 131 is communicated with the receiving cavity 310, and the first hole structure 131 is close to the bottom of the receiving cavity 310. The first filter element 112 is connected to the body 300, and a storage cavity 140 is formed between the first filter element 112 and the inner wall of the receiving cavity 310. The first filter element 112 extends from the bottom of the receiving cavity 310 to the top of the receiving cavity 310, and the orthographic projection of the first hole structure 131 on the first filter element 112 is located on the first filter element 112. The air inlet of the fan component 200 is connected to the top of the accommodating cavity 310. When the fan component 200 is running, the air in the external environment enters the accommodating cavity 310 through the first hole structure 131, the storage cavity 140 and the first filter element 112 in sequence, and is discharged to the external environment through the fan component 200.

[0067] It should be pointed out that in this embodiment, the first filter element 112 only needs to cover the first hole structure 131, and its shape is not specifically limited. In this embodiment, the principle that the closer to the air inlet of the fan component 200, the faster the wind speed is can also be used, so that the air entering the storage cavity 140 through the first hole structure 131 is distributed more evenly through the first filter element 112, increasing the area of ​​the first filter element 112 involved in the filtration, thereby making full use of the first filter element 112 and avoiding unnecessary waste of resources of the first filter element 112. At the same time, since the above structure only needs to set the first hole structure 131 to fully utilize the first filter element 112, compared with the existing method in which the first hole structure 131 needs to cover the outer surface of the first filter element 112 to fully utilize the first filter element 112, the present application can reduce the number of openings on the side wall of the body 300, thereby reducing production costs.

[0068] Furthermore, as the air passes through the first filter element 112 in a relatively uniform distribution, the dirt carried in the air will also be relatively uniformly distributed on the first filter element 112, thereby reducing the possibility of dirt being concentrated and accumulated on the portion of the first filter element 112 corresponding to the first hole structure 131, causing blockage of the air duct, thereby improving the energy efficiency of the air purification device. In addition, even if the dirt is concentrated and accumulated on the portion of the first filter element 112 corresponding to the first hole structure 131, causing blockage of the air duct, the blocked dirt will also be pushed upwards under the effect of the wind speed difference between the upper and lower parts of the first filter element 112, thereby pushing the dirt upwards to the upper part of the first filter element 112, thereby clearing the blockage, further reducing the possibility of blockage of the air duct.

[0069] Regarding the specific form of the first hole structure 131 , reference may be made to the contents in the above-mentioned embodiment, which will not be described in detail here.

[0070] Based on the same inventive concept, the present application also provides a filter device 100. The filter device 100 includes at least a filter element assembly 110 and a housing assembly 120. The filter element assembly 110 is constructed as a barrel-shaped structure with an opening 111 at the top, and the opening 111 is used to communicate with the air inlet of the fan component 200. The housing assembly 120 is sleeved on the outer wall of the filter element assembly 110, and a storage cavity 140 is also provided between the inner wall of the housing assembly 120 and the outer wall of the filter element assembly 110. A purification hole 130 is provided on the outer wall of the housing assembly 120, and the purification hole 130 may include at least a first hole structure 131, which is arranged around the axis of the housing assembly 120 and close to the bottom of the housing assembly 120. When the fan component 200 is running, the air in the external environment enters the interior of the filter element assembly 110 through the purification hole 130, the storage cavity 140 and the filter element assembly 110 in sequence, and is discharged to the external environment through the fan component 200.

[0071] Further, the filter element assembly 110 includes at least a first filter element 112, which is constructed as a continuous annular structure, and has at least one arc-shaped portion 1121. The storage cavity 140 is formed between the outer wall of the arc-shaped portion 1121 and the inner wall of the housing assembly 120, and the remaining portion of the first filter element 112 after the arc-shaped portion 1121 is in contact with the housing assembly 120. The number of purification holes 130 is the same as the number of arc-shaped portions 1121, and the purification holes 130 correspond to the arc-shaped portions 1121 one by one, the first hole structure 131 extends from one end of the arc-shaped portion 1121 to the other end of the arc-shaped portion 1121, and the purification hole 130 also includes a second hole structure 132 and a third hole structure 133, the second hole structure 132 extends upward from one end of the first hole structure 131, and the third hole structure 133 extends upward from the other end of the first hole structure 131.

[0072] Furthermore, the filter device 100 further includes a hair suction piece 150. The hair suction piece 150 is detachably connected to the first filter element 112, and the hair suction piece 150 covers the outer wall of the arc-shaped portion 1121, and the storage cavity 140 is located between the hair suction piece 150 and the inner wall of the housing assembly 120. When the fan component 120 is running, air in the external environment passes through the purification hole 130, the storage cavity 140, the hair suction piece 150 and the first filter element 112 in sequence and enters the interior of the filter element assembly 110.

[0073] Regarding the specific structures of the filter element assembly 110, the housing assembly 120, the purification hole 130 and the hair suction piece 150, reference may be made to the contents in the above-mentioned embodiments, which will not be described in detail here.

[0074] The technical solution provided in the embodiments of the present application is described below in conjunction with several specific application scenarios.

[0075] Application scenario 1

[0076] The air purification device at the user's home displays that the filter device needs to be replaced. After the user pulls out the filter device from the side of the body, the housing assembly is removed from the side of the filter device.

[0077] After the shell assembly is removed, the user finds that the outer wall of the arc-shaped portion is still covered with a layer of hair suction pieces, and the floating hair purified by the air purification device adheres to the hair suction pieces. After the user pulls the hair suction piece off the outer wall of the arc-shaped portion, only fine dust remains on the outer wall of the arc-shaped portion. In this way, the user only needs to replace the hair suction piece, and does not need to replace the first filter element, which greatly reduces the cost of use. At the same time, the hair suction piece has a high adhesion effect on floating hair, and during the process of removing the hair suction piece, the possibility of floating hair falling off the hair suction piece and being inhaled by the human body can be reduced.

[0078] In addition, users have also found that during the purification process of the air purification equipment, the air inhaled through the purification hole does not pass directly through the hair suction piece for filtration. Some of the inhaled air flows upward and then passes through the hair suction piece. This makes the floating hair adhered to the hair suction piece more evenly distributed on the hair suction piece, rather than being blocked at the hair suction piece corresponding to the purification hole. The hair suction piece can be fully utilized, and the blockage of the air duct can be alleviated, thereby improving the energy efficiency of the air purification equipment.

[0079] Application scenario 2

[0080] An air purification device with an integrated walking mechanism is used in an office space with four offices.

[0081] Managers can set the purification time of the air purification equipment in each office every day. When the purification time of the air purification equipment in one office reaches the preset time, the air purification equipment can automatically move to another office using the walking function of the walking mechanism. In this way, one air purification equipment can purify the air in four offices, so there is no need to place an air purification equipment in each office, which reduces the cost of use.

[0082] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
