Description

Technical Field

[0001] The utility model relates to the field of household electrical appliances, in particular to an air treatment device. Background Art

[0002] The power harness of air handling equipment such as air humidifiers and air purifiers is usually placed on one side of the equipment in a stretched state. When the air handling equipment needs to be stored or moved, the storage process may cause the power harness to be dragged. During the dragging process, the power harness is easily contaminated with dirt, and the storage space occupied by the power harness is relatively large, making it difficult to store.

[0003] At present, some models of humidifiers on the market have a power harness storage device on the bottom shell of the humidifier, so that after using the humidifier, the power harness can be wrapped around the ribs in the storage groove, making the storage of the power harness more convenient.

[0004] However, when the power harness is stored in the above manner, the power harness needs to be bent multiple times and pressed onto the fixed ribs in the storage slot for winding. The storage slot has a small space and is inconvenient to operate. Utility Model Content

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the purpose of the utility model is to provide an air treatment device, wherein the wire harness storage device in the storage cavity is designed as a movable structure, and when the wire harness storage device slides to the second position, at least part of the structure of the wire harness storage device extends out of the storage cavity, and when storing, the power harness is directly wound around the extended part of the wire harness storage device, and when in use, the power harness can be stretched out of the wire harness storage device by simply loosening the power harness in the reverse direction, which is less restricted by space and easy to operate.

[0006] According to an embodiment of the utility model, an air treatment device includes: an equipment body, including a shell, a side wall of the shell is provided with a storage cavity opened along a first direction, and the equipment body is provided with a power connection structure; a power harness is passed through the storage cavity and connected to the power connection structure; a harness storage device is provided in the storage cavity and is constructed to move between a first position and a second position along the first direction relative to the equipment body, wherein in the first position, the harness storage device is in the storage cavity, and in the second position, at least part of the structure of the harness storage device is located outside the storage cavity.

[0007] A storage cavity is provided on the outer shell of the device body, and the power harness is stored in the storage cavity when not in use. The power harness occupies less space outside the device, reducing the possibility of the power harness coming into contact with dirt. When the power harness needs to be stored, the harness storage device is slid to the second position, at which point at least part of the structure of the harness storage device extends out of the storage cavity, the power harness is wound around the extended portion of the harness storage device, and then the harness storage device is slid to the first position to complete the storage; when the power harness is to be used, the harness storage device is slid from the first position to the second position, and the power harness is loosened in the opposite direction of storage, so that the power harness can be extended and detached from the harness storage device, and plugged in for use. The device is less restricted by space and is easy to operate.

[0008] In some embodiments, one of the housing and the harness storage device is provided with a guide post, and the other is provided with a guide hole, the guide post and the guide hole both extend along the first direction, and the guide post and the guide hole are guided and matched. In this way, the sliding direction of the harness storage device can be accurately and reliably restricted by the guiding match between the guide post and the guide hole.

In this way, the wire harness storage device is limited in the first position so that the wire harness storage device is stored in the storage cavity, and the wire harness storage device is limited in the second position so that the wire harness storage device will not fall off the guide column.

[0010] According to some embodiments of the utility model, the limiting structure includes a first limiting protrusion, the first limiting protrusion is located on the side wall of the guide column, the matching structure includes a clamping block, the clamping block is fixed to the inner wall of the guide hole, and when the wire harness storage device is in the first position, the clamping block is located on the side of the first limiting protrusion away from the opening along the first direction. In this way, the wire harness storage device is limited by the matching of the first limiting protrusion and the clamping block, so that the wire harness storage device is stored in the storage cavity.

[0011] According to some embodiments of the utility model, the projection of the first limiting protrusion on the reference plane and the projection of the clamping block in the reference plane at least partially overlap, the reference plane is perpendicular to the first direction, and the clamping block is an elastic block. In this way, the overlapping part of the projection of the first limiting protrusion and the clamping block in the first reference plane cooperates with each other to limit the wiring harness storage device at the first position, so as to prevent the wiring harness storage device stored in the storage cavity from sliding out of the first position and causing the power harness to become loose.

[0012] According to some embodiments of the utility model, a guide portion is provided on the inner wall of the card block opposite to the guide column, and the aperture of the guide portion gradually increases along the first direction and toward the inner side of the receiving cavity. This arrangement reduces the wall thickness of the card block in the direction toward the shell, improves the elasticity of the structure at the card block, and facilitates the cooperation between the card block and the first limiting protrusion.

[0013] According to some embodiments of the utility model, the limiting structure further includes a second limiting protrusion, the second limiting protrusion is located on the side wall of the guide column, the second limiting protrusion is located on the side of the first limiting protrusion close to the opening, and when the wire harness storage device is in the second position, the clamping block abuts against the second limiting protrusion. In this way, when the wire harness storage device is in the second position, the clamping block cooperates with the second limiting protrusion to limit the wire harness storage device, thereby preventing the wire harness storage device from falling off the guide column, and facilitating the storage and extension of the wire harness.

[0014] According to some embodiments of the utility model, in the reference plane, the edge of the projection of the second limiting protrusion exceeds the edge of the projection of the first limiting protrusion. In this way, in the radial direction of the guide column, the radial outer edge of the second limiting protrusion is raised to exceed the radial outer edge of the first limiting protrusion, so as to improve the reliability of the second limiting protrusion limiting the block, and prevent the wiring harness storage device from falling off the guide column when it is in the second position.

This arrangement facilitates the connection of the end of the power harness connected to the electrical device to the air handling device for easy storage, and also facilitates the use of the power harness.

[0016] According to some embodiments of the utility model, the wire harness storage device includes a first clamping plate, a second clamping plate and a connecting column, the first clamping plate and the second clamping plate are respectively fixed to the two ends of the connecting column, the second clamping plate is located on the side of the first clamping plate away from the opening, and the guide column defines the guide hole; a winding space is formed between the first clamping plate and the second clamping plate, and the winding space is connected to the assembly hole. In this way, by limiting the winding space for storing the power harness between the first clamping plate and the second clamping plate, when storing, the power harness is wound around the outer wall of the guide column in the winding space, and the operation is simple and convenient.

[0017] According to some embodiments of the utility model, the second clamping plate is provided with the connection groove, and the connection groove penetrates the second clamping plate along the thickness direction of the second clamping plate to connect the winding space and the assembly hole. In this way, after the end of the power harness connected to the electrical device is inserted into the assembly hole, the power harness directly passes through the connection groove and extends into the winding space for storage, which reduces the length of the power harness exposed outside the second clamping plate, helps to reduce the contact between the power harness and external dirt, and at the same time makes the winding operation more convenient.

[0018] According to some embodiments of the utility model, at least one of the first clamping plate and the second clamping plate is provided with a toggle structure, so that the power supply storage device can be more conveniently pulled out from the storage space by providing the toggle structure.

[0034] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0035] The power harness of air handling equipment such as air humidifiers and air purifiers is usually placed on one side of the equipment in a stretched state. When the air handling equipment needs to be stored or moved, the storage process may cause the power harness to be dragged. During the dragging process, the power harness is easily contaminated with dirt, and the storage space occupied by the power harness is relatively large, making it difficult to store.

[0036] At present, some models of humidifiers on the market have a power harness storage device on the bottom shell of the humidifier, so that after using the humidifier, the power harness can be wrapped around the ribs in the storage slot, making the storage of the power harness more convenient. However, when using the above method to store the power harness, the power harness needs to be bent multiple times and pressed into the fixed ribs in the storage slot for winding. The space in the storage slot is small and the operation is inconvenient.

[0037] In view of this, the utility model provides an air handling device, in which a wire harness storage device in a storage cavity is designed to be a movable structure. When the wire harness storage device slides to the second position, at least a portion of the structure of the wire harness storage device extends out of the storage cavity. When storing, the power harness is directly wound around the extended portion of the wire harness storage device. When in use, the power harness can be extended and detached from the wire harness storage device by simply loosening the power harness in reverse. The space restriction effect is small and the operation is convenient.

[0039] In the description of the present invention, "first feature" or "second feature" may include one or more of the features.

[0040] In the description of the present invention, "plurality" means two or more.

[0041] In the description of the present invention, a first feature being “above” or “below” a second feature may include that the first and second features are directly in contact with each other, or may include that the first and second features are not in direct contact but are in contact with each other via another feature therebetween.

[0042] In the description of the present invention, a first feature “above”, “over” and “above” a second feature includes the first feature being directly above and obliquely above the second feature, or simply means that the first feature is horizontally higher than the second feature.

[0043] Reference below Figure 1-Figure 7 An air treatment device 100 according to an embodiment of the present invention is described.

[0044] refer to Figure 1-Figure 5 An air treatment device 100 of this embodiment may be an air humidifier, an air purifier or other types of air treatment devices 100. The air treatment device 100 may be a household air treatment device 100, or a commercial or industrial air treatment device 100, etc.

[0045] Specifically, the air treatment device 100 may include a device body 1, a power harness 2 and a harness storage device 3. The device body 1 may include a housing 10. The side wall of the housing 10 is provided with a storage cavity 11 opened along a first direction. The power harness 2 is passed through the storage cavity 11 and can be stored in the harness storage device 3. For example, the power harness 2 can be passed through the inner wall of the storage cavity 11 opposite to the opening to connect with the electric control components located inside the housing, such as a circuit board. In the storage cavity 11, the harness storage device 3 moves between a first position and a second position along the first direction, such as sliding, rotating or other forms of movement. The harness storage device 3 can move relative to the housing 10 by itself, or can move relative to the housing 10 under the drive of an external drive device.

[0046] When the harness storage device 3 is in the first position, the harness storage device 3 stores the power harness 2 in the storage cavity 11. At this time, the power harness 2 can be stored on the harness storage device 3, and the harness storage device 3 and the power harness 2 can be stored together, or the power harness 2 can be in use, and only the harness storage device 3 can be stored separately. When the harness storage device 3 is in the second position, at least part of the structure of the harness storage device 3 is located outside the storage cavity 11. At this time, it is convenient to store the power harness 2 on the harness storage device 3, or it is convenient to extend the power harness 2 from the harness storage device 3 to the outside of the storage cavity 11. It can be understood that when the wire harness storage device 3 is in the second position, only a portion of the wire harness storage device 3 can be moved outside the storage cavity 11, and a portion of the wire harness storage device 3 can still be in the storage cavity 11, or, the entire wire harness storage device 3 can be outside the storage cavity 11. Under the condition that the power harness 2 can be smoothly extended and detached from the wire harness storage device 3, the portion of the wire harness storage device 3 exposed to the storage cavity 11 can be reasonably adjusted according to actual needs.

[0047] For the convenience of description, the first direction may be: when the air treatment device 100 is in a state such as Figure 1 When the air treatment device 100 is in a vertical placement state, the air treatment device 100 can be in a normal use state or an unused state, and the first direction can be a direction perpendicular to the vertical shell 10 of the air treatment device 100.

[0048] A storage cavity 11 is provided on the housing 10 of the device body 1. The power harness 2 is stored in the storage cavity 11 when not in use. The power harness 2 occupies less space outside the device, reducing the possibility of the power harness 2 coming into contact with dirt. When the power harness 2 needs to be stored, the harness storage device 3 is slid to the second position. At this time, at least part of the structure of the harness storage device 3 extends out of the storage cavity 11. The power harness 2 is wound around the extended part of the harness storage device 3, and then the harness storage device 3 is slid to the first position to complete the storage. When the power harness 2 is to be used, the harness storage device 3 is slid from the first position to the second position, and the power harness 2 is loosened in the opposite direction of the storage. The power harness 2 can be extended and detached from the harness storage device 3, and plugged in for use. The device is less restricted by space and is easy to operate.

[0049] It can be understood that at the second position, at least part of the structure of the wire harness storage device 3 is located outside the storage cavity 11. At this time, the part of the structure of the wire harness storage device 3 located outside the storage cavity 11 at least includes a storage space for storing the power harness 2, such as the winding space described below, to facilitate the storage or extension of the power harness 2. Of course, the part of the structure of the wire harness storage device 3 located outside the storage cavity 11 can also include more structures of the wire harness storage device 3, and the present application does not limit this.

[0050] refer to Figure 2 and Figure 3 In some embodiments, a guide column 12 extending in a first direction is provided in the storage cavity 11 of the housing 10, and a guide hole 31 is provided on the wire harness storage device 3. The guide hole 31 can extend in the first direction, and the guide column 12 and the guide hole 31 are guided to cooperate. Of course, in other embodiments, the wire harness storage device 3 can also have a guide column 12, and the storage cavity 3 has a guide hole 31. The guide column 12 and the guide hole 31 both extend in the first direction, and the guide cooperation between the guide column 12 and the guide hole 31 can also be achieved. For example, the cross-section of the guide column 12 can be circular, square or other arbitrary shapes, and the shape of the guide hole 31 cooperates with the guide column 12. The guide column 12 can be a solid column structure or a hollow column structure. Among them, the guiding cooperation refers to guiding the movement direction of the wire harness storage device through the cooperation of the guide hole 31 and the guide column 12, so as to avoid deviation or shaking of the wire harness storage device 3 during the movement, so as to ensure the stability of the movement. For example, in this embodiment, the wire harness storage device 3 can be mounted on the guide column 12 through the guide hole 31, and the wire harness storage device 3 can slide smoothly between the first position and the second position along the length direction of the guide column 12 through the guiding effect of the guide column 12.

[0051] refer to Figures 4 to 7According to some embodiments of the utility model, a limiting structure is formed on the guide column 12, and a matching structure that cooperates with the limiting structure is provided in the guide hole 31; the limiting structure and the matching structure are configured to limit the wire harness storage device 3 when the wire harness storage device 3 is in any one of the first position and the second position.

[0052] In this embodiment, when the harness storage device 3 is in the first position, the harness storage device 3 is limited by the cooperation of the limiting structure and the matching structure, so that the power harness 2 is completely stored in the storage cavity 11, reducing the space occupied by the power harness 2. When the harness storage device 3 is in the second position, the harness storage device 3 is limited by the cooperation of the limiting structure and the matching structure, so as to prevent the harness storage device 3 from falling off the guide column 12, and facilitate the storage and extension of the power harness 2.

[0053] Continue to refer Figure 6 and Figure 7 Further, the limiting structure may include a first limiting protrusion 121, which is located on the side wall of the guide column 12 and protrudes outward along the radial direction of the guide column 12. The matching structure may include a clamping block 311, which is fixed to the inner wall of the guide hole 31 and matches with the first limiting protrusion 121. When the harness storage device 3 is in the first position, in the first direction, the clamping block 311 is located on the side of the first limiting protrusion 121 away from the opening, and the clamping block 311 and the first limiting protrusion 121 are against each other in the axial direction of the guide column 12, so that the first limiting protrusion 121 limits the movement of the clamping block 311. At this time, the harness storage device 3 and the power harness 2 are both stored in the storage cavity 11. During the movement of the air treatment device 100, even if it falls over, the harness storage device 3 will not fall off from the storage cavity 11, so as to prevent the power harness 2 from being contaminated. Of course, in other embodiments, the limit structure may also be a travel switch. In this case, the matching structure may be a contact corresponding to the travel switch. When the travel switch contacts the contact, the travel switch limits and locks the wiring harness storage device 3 in the first position.

[0054] It can be understood that, since the rotation direction of the wire harness storage device 3 on the guide column 12 is not limited, in order to avoid the disengagement between the clamping block 311 and the first limiting protrusion 121, causing the wire harness storage device 3 to slide out when in the first position, at least one of the clamping block 311 and the first limiting protrusion 121 can be set to an annular structure. For example, the clamping block 311 is an annular structure, and the first limiting protrusion 121 has an annular segment, or the clamping block 311 has an annular segment, and the first limiting protrusion 121 is an annular structure. Of course, the clamping block 311 and the first limiting protrusion 121 can also have an annular structure.

[0055] Furthermore, in order to ensure the cooperation effect between the first limiting protrusion 121 and the block 311, a reference plane is established in a direction perpendicular to the sliding direction of the wire harness storage device 3, that is, in a direction perpendicular to the first direction. In the reference plane, the projection of the first limiting protrusion 121 and the projection of the block 311 at least partially overlap. For example, the radial outer end of the first limiting protrusion 121 is on the outside of the radial inner end of the block 311, so that the first limiting protrusion 121 and the block 311 can be offset against each other along the axial direction of the guide column 12, thereby achieving a limiting effect.

[0056] Furthermore, since it is necessary to slide the wire harness storage device 3 from the first position to the second position to store or extend the power harness 2, the block 311 can be an elastic block. Since the block 311 is elastic, when the user pushes the wire harness storage device 3 to slide to the second position through external force, the block 311 can be deformed to a certain extent, so that when the wire harness storage device 3 moves to the second position, the radial inner end of the block 311 passes over the first limiting protrusion 121 and reaches the other side of the first limiting protrusion 121, so that the wire harness storage device 3 can be separated from the limiting constraint of the first limiting protrusion 121 and move from the first position to the second position. At the same time, it can also avoid breakage and damage to the block 311 or the first limiting protrusion 121.

[0057] The block 311 may be made of an elastic material, and the elasticity of the block 311 may be brought about by the material of the block 311 . For example, the block 311 may be made of a material with good elasticity such as rubber, plastic or spring steel.

[0058] refer to Figure 6 and Figure 7Of course, the block 311 can be an elastic structural member, that is, the elasticity of the block 311 can also be brought about by the structure of the block 311. For example, the structure that makes the block 311 elastic can be that the guide hole 31 is extended along the first direction, and a deformation sleeve is formed on one side of the wire harness storage device 3. The deformation sleeve can be a ring structure with a certain thickness. The block 311 is located in the deformation sleeve. Compared with the wire harness storage device 3, the thickness of the deformation sleeve is small in the radial direction of the guide column 12, and the expansion effect is good when the force is applied, which facilitates the block 311 to pass through the position of the first limiting protrusion 121. A guide portion 3111 can also be formed on the side wall of the block 311 facing the guide column 12. In the direction along the first direction and close to the housing 10, the aperture of the guide portion 3111 gradually increases, that is, the guide portion 3111 can be a tapered hole surface. The farther away from the housing 10, the smaller the aperture. The thickness of the limiting portion on the block 311 facilitates the deformation of the block 311 through the first limiting protrusion 121. In addition, in order to improve the limiting effect of the block, a limiting step can be formed on the side of the block 311 facing the first limiting protrusion 121. When the wire harness storage device 3 is in the first position, the limiting step abuts against the first limiting protrusion 121, so that the wire harness storage device 3 will not be separated from the first position without being affected by external force.

[0059] refer to Figure 3 , Figure 6 and Figure 7 According to some embodiments of the utility model, the limiting structure may further include a second limiting protrusion 122, which is formed on the side wall of the guide column 12 and protrudes from the side wall of the guide column 12. The second limiting protrusion 122 is located on the side of the first limiting protrusion 121 close to the opening. When the harness storage device 3 is in the second position, the clamping block 311 abuts against the second limiting protrusion 122. When the harness storage device 3 needs to be slid from the first position to the second position, a force is applied to the harness storage device 3 along the first direction, and the clamping block 311 undergoes elastic deformation, passes through the first limiting protrusion 121, slides to the second limiting protrusion 122, and abuts against the second limiting protrusion 122. At this time, the harness storage device 3 is in the second position, and the power harness 2 is stored or extended for use. The limiting effect of the second limiting protrusion 122 prevents the harness storage device 3 from falling off the guide column 12.

[0060] When the wire harness storage device 3 is mounted on the guide column 12, the guide hole 31 of the wire harness storage device 3 is aligned with the guide column 12, and a force is applied toward the housing 10 along the first direction. When the block 311 contacts the second limiting protrusion 122, the guide portion 3111 and the guide inclined surface cooperate with each other to squeeze, and the block 311 expands outward, so that the block 311 passes through the second limiting protrusion 122. When the wire harness storage device 3 is located in the second position, the second limiting protrusion 122 abuts against the limiting step of the block 311, and the wire harness storage device 3 will not fall off.

[0061] Further, in the reference plane, the edge of the projection of the second limiting protrusion 122 exceeds the edge of the projection of the first limiting protrusion 121. Since the clamping block 311 has elasticity to pass through the first limiting protrusion 121, by making the edge of the projection of the second limiting protrusion 122 exceed the edge of the projection of the first limiting protrusion 121, in the radial direction of the guide column 12, the edge of the second limiting protrusion 122 is larger than the edge of the first limiting protrusion 121, so as to prevent the clamping block 311 from sliding past the second limiting protrusion, causing the wire harness storage device 3 to fall off the guide column 12.

[0062] In this embodiment, the second limiting protrusion 122 can have the same structure as the first limiting protrusion 121, that is, the second limiting protrusion 122 can be a protrusion radially away from the guide column 12. Of course, in order to facilitate the installation of the wire harness storage device 3 on the guide column 12, the second limiting protrusion 122 can include a spring sheet, and a gap is set between the two sides of the spring sheet and the guide column 12 to increase the elasticity of the spring sheet. The spring sheet has an installation limiting protrusion radially away from the outer wall of the guide column 12, and the installation limiting protrusion has an installation inclined surface that cooperates with the guide portion 3111 on the side away from the housing 10, and the installation limiting protrusion is formed with an abutment step on the side facing the housing 10.

[0063] refer to Figure 3 , Figure 6 and Figure 7 In some embodiments, a power connection structure may be provided in the device body 1, and an assembly hole 123 is formed on the guide column 12. The power connection end of the power harness 2 is inserted into the assembly hole 123 and connected to the power connection structure. With this arrangement, on the one hand, the space on the inner side of the guide column 12, i.e., the assembly hole 123, can be used for routing, which simplifies the line layout of the power harness 2 and reduces space occupation. On the other hand, the power harness 2 can be wound around the harness storage device 3 by passing through the assembly hole 123, making the matching mode of the power harness 2 and the harness storage device 3 simpler. Moreover, even if part of the power harness 2 is stored in the harness storage device 3, the air treatment device 100 can be used by only connecting the plug end of the power harness 2 to electricity, which is convenient for the use of the power harness 2. For example, when the installation space of the air treatment device 100 is small when it is working, or the power socket is close to the air treatment device 100, part of the wiring harness can be stored in the wiring harness storage device 3, and the plug of the power harness 2 is inserted into the socket to draw power, thereby reducing the space occupied by the power harness 2 and avoiding excessive exposure of the power harness 2 outside the air treatment device 100, which may cause the power harness 2 to get dirty.

[0064] Among them, the functions of the power connection structure generally include: converting the power supply into a voltage suitable for the components inside the air treatment device 100 and ensuring the safe operation of the entire system. The power connection structure may include but is not limited to: a power conversion module, a voltage distribution module, a circuit control module and other functional modules. The functional modules are connected by connecting wires, and the connecting wires are connected with interfaces. The end of the power harness 2 connected to the power supply is inserted into the assembly hole 123 and connected to the interface to input current into the air treatment device 100.

[0065] According to some embodiments of the utility model, the wire harness storage device 3 may include a first clamping plate 32, a second clamping plate 33 and a connecting column 34, the first clamping plate 32 and the second clamping plate 33 are respectively fixed to the two ends of the connecting column 34, the second clamping plate 33 is located on the side of the first clamping plate 32 away from the opening, the guide column 12 may define a guide hole 31, and the guide hole 31 passes through the first clamping plate 32 and the second clamping plate 33, the shape of the first clamping plate 32 and the second clamping plate 33 may be adapted to the shape of the storage cavity 11; between the first clamping plate 32 and the second clamping plate 33, a winding space is formed on the outer wall of the connecting column 34, the winding space is connected to the assembly hole 123, and the matching structure, i.e., the block 311, may be provided on the connecting column 34 or on the first clamping plate 32. The end of the power harness 2 connected to the power supply is inserted into the assembly hole 123, and then the power harness 2 is wound on the outer wall of the connecting column 34, so that the power harness 2 is stored in the winding space for easy storage.

[0066] refer to Figure 2 and Figure 7 Furthermore, a connecting groove 331 is provided on the second clamping plate 33, and the connecting groove 331 extends radially of the second clamping plate 33, and the connecting groove 331 penetrates the second clamping plate 33 along the thickness direction of the second clamping plate 33, and the width of the connecting groove 331 can be adapted to the diameter of the power harness 2, and in the radial outward direction along the second clamping plate 33, the width of the connecting groove 331 is equal at all locations, or the width of the connecting groove 331 gradually increases to connect the winding space and the assembly hole 123. When the power harness 2 is wound on the connecting column 34, the power harness 2 needs to be extended from the outside of the second clamping plate 33 into the winding space. Part of the power harness 2 is exposed outside the second clamping plate 33, which is not only unsightly, but also may cause the exposed part of the power harness 2 to rub against other objects when the air treatment device 100 is moved, resulting in contamination or even damage. Therefore, a connecting groove 331 is opened on the second clamping plate 33. The connecting groove 331 not only penetrates the second clamping plate 33 along the thickness direction of the second clamping plate 33, but also extends along the edge of the second clamping plate 33 to the outer wall of the connecting column 34. When the power harness 2 is stored, it is led out from the assembly hole 123 and directly enters the winding space along the connecting groove 331. The storage is convenient and quick, and the exposed part of the power harness 2 is reduced, thereby improving the aesthetics.

[0067] refer to Figure 2 , Figure 6 and Figure 7 According to some embodiments of the present invention, a toggle structure is provided on at least one of the first clamping plate 32 and the second clamping plate 33. For example, the toggle structure can be provided on the first clamping plate 32; or, the toggle structure can be provided on the second clamping plate 33; of course, the toggle structure can also be provided on both the first clamping plate 32 and the second clamping plate 33. When the wire harness storage device 3 is stored in the storage cavity 11, the wire harness storage device 3 can be pressed along the first direction. When the wire harness storage device 3 is taken out of the storage cavity 11, it is inconvenient to toggle out the wire harness storage device 3 due to insufficient space in the storage cavity 11. Therefore, a toggle structure is provided on one of the first clamping plate 32 and the second clamping plate 33 to facilitate the toggle operation of taking out the wire harness storage device 3 from the storage cavity 11.

[0068] Further, the toggle structure may include an toggle protrusion 332, which protrudes in a first direction away from the housing 10, and on the clamping plate where the toggle protrusion 332 is provided, the toggle protrusion 332 is located on the surface of the side away from the housing 10. For example, when the toggle protrusion 332 is provided on the first clamping plate 32, it is located on the side of the first clamping plate 32 away from the housing 10. It should be noted that since the second clamping plate 33 is located on the outside of the first clamping plate 32, the projection of the first clamping plate 32 in the reference plane needs to exceed the second clamping plate 33, that is, the edge size of the first clamping plate 32 exceeds the edge size of the second clamping plate 33, so as to ensure that the finger can be inserted into the toggle protrusion 332 on the first clamping plate 32 through the second clamping plate 33 to take out the wire harness storage device 3. Similarly, when the toggle protrusion 332 is provided on both the first clamping plate 32 and the second clamping plate 33, the above conditions must still be met. Of course, the moving protrusion 332 can also be only set on the surface of the second clamping plate 33 on the side away from the shell 10. In this case, the user's finger can be directly inserted into the moving protrusion 332 and moved away from the shell 10 to take out the wire harness storage device 3. The operation is simple and quick.

[0069] It is understandable that when the toggle protrusion 332 is provided on the surface of the second clamping plate 33 away from the housing 10, the toggle protrusion 332 can be formed on the edge of the second clamping plate 33, or on the surface close to the guide hole 31. In order to save more effort, the toggle protrusion 332 can be set to an even number, symmetrically arranged around the axis of the connecting shaft. For example, two toggle protrusions 332 are provided, symmetrically arranged 180° about the axis of the connecting shaft, and the operator inserts two fingers into the toggle protrusion 332 to toggle, which saves more effort. Of course, the number of the toggle protrusions 332 can also be other numbers, and the present application does not limit this.

[0070] The use principle of the wire harness storage device 3 of the embodiment of the utility model is:

[0071] When the power harness 2 needs to be stored, the operator acts on the toggle convex portion 332 to toggle the harness storage device 3 to the second position, and passes the end of the power harness 2 connected to the power supply through the guide hole 31 and the assembly hole 123 in sequence to connect to the power connection structure. The power harness 2 passes through the connection groove 331, is wound and stored in the winding space between the first clamping plate 32 and the second clamping plate 33, and then the end of the power harness 2 close to the plug is clamped in the connection groove 331, and then the harness storage device 3 is pushed to the first position to complete the storage.

[0072] When the power harness 2 needs to be stretched out for use, the operator acts on the toggle protrusion 332 to toggle the harness storage device 3 to the second position, removes one end of the plug of the power harness 2, unwinds the power harness 2 from the winding space, takes out the length required for use, and then pushes the harness storage device 3 to the first position.
