DETAILED DESCRIPTION

[0030] 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 intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0031] The utility model relates to a drying device, which comprises a heating component 100 and a bracket component 200.

[0032] like Figure 1 and Figure 2As shown, the heating component 100 includes a first heat conducting plate 110, a second heat conducting plate 120 and an electric heating element 130. The outer contours of the first heat conducting plate 110 and the second heat conducting plate 120 can be set to the same shape. The first heat conducting plate 110 and the second heat conducting plate 120 can be set to a circular, rectangular or other shape. In this embodiment, the first heat conducting plate 110 and the second heat conducting plate 120 are both rectangular. The material of the first heat conducting plate 110 and the second heat conducting plate 120 can be selected from a rock plate or a metal plate, and the metal plate is preferably an aluminum plate. Among them, the second heat conducting plate 120 is preferably made of a rock plate as the front of the heating component 100. The rock plate has the ability of heat conduction, heat storage, and far infrared generation, and has good thermal conductivity. The second heat conducting plate 120 is preferably an aluminum plate as the back of the heating component 100. The aluminum plate is light in weight and has strong thermal conductivity. The metal plate structure also facilitates the connection between the second heat conducting plate 120 and the bracket assembly 200. The electric heating element 130 can be a structure such as an electric heating wire and an electric heating plate. In this embodiment, the electric heating element 130 uses a graphene heating film. The graphene heating film can be set in a shape that matches the first heat conducting plate 110 and the second heat conducting plate 120. The graphene heating film is attached to the plate surface of the second heat conducting plate 120, and then the first heat conducting plate 110 and the second heat conducting plate 120 are stacked in the thickness direction, and then the graphene heating film is clamped between the first heat conducting plate 110 and the second heat conducting plate 120. The bracket assembly 200 is installed on the first heat conducting plate 110, and the bracket assembly 200 has a plurality of chucks 210, and each chuck 210 is distributed along the circumference of the heating component 100. A clamping space is defined between each chuck 210. The heating component 100 is placed in the clamping space. The bracket assembly 200 can move so that the clamping space is expanded or reduced relative to the center of the heating component 100. In this embodiment, the heating component 100 is provided with four chucks 210, and the heating component 100 is rectangular, and each chuck 210 corresponds to one side of the heating component 100. During installation, each chuck 210 is moved in the direction of the clamping space becoming larger. The heating component 100 is placed in the clamping space. Then each chuck 210 is moved in the direction of the clamping space shrinking, and the clamping space shrinks until each chuck 210 is respectively abutted on the four peripheries of the heating component 100, that is, the four peripheries of the first heat conducting plate 110 and the four peripheries of the second heat conducting plate 120 are aligned and positioned one by one. At the same time, the chuck 210 is clamped on the edge of the heating component 100, and the first heat conducting plate 110 and the second heat conducting plate 120 are clamped in the thickness direction, so as to complete the fixing of the heating component 100. Finally, the heating component 100 can be further positioned by gluing, screw locking, etc., or the bracket assembly 200 can be locked and fixed in the current position, thereby completing the fixing of the heating component 100. By cooperating with the movable clamp 210 on the bracket assembly 200, the first heat conducting plate 110 and the Dio heat conducting plate can be quickly aligned and fixed, and the assembly efficiency is high.When in use, objects such as towels or clothes can be placed on the heating component 100, and the first heat conducting plate 110 and the second heat conducting plate 120 are used to perform double-sided heating to dry both sides of the object, thereby greatly improving the drying efficiency of the object.

[0033] In some embodiments of the present invention, Figure 2 , Figure 5 , Figure 7 and Figure 8 As shown, the bracket assembly 200 includes a first moving group 300, a second moving group 400 and a gear 500. The first moving group 300 and the second moving group 400 are cross-distributed, which can be a cross-distribution as shown in the figure, or an X-shaped cross-distribution. The first moving group 300 and the second moving group 400 are slidably mounted on the first heat conducting plate 110. The first moving group 300 and the second moving group 400 are meshed and driven by the gear 500. The gear 500 can be set as one or more combinations. The gear 500 can be rotatably mounted on the first heat conducting plate 110. A chuck 210 is provided at both ends of the first moving group 300, and a chuck 210 is provided at both ends of the second moving group 400. The first moving group 300 is linearly translated on the first heat conducting plate 110, and the second moving group 400 is linearly telescopic on the first heat conducting plate 110. As shown in FIG. Figure 1 As shown, the heating assembly is placed in a vertical direction or a direction with a certain slope. First, the bracket assembly 200 is installed on the rear side of the first heat conducting plate 110, and the electric heating element 130 is installed on the rear side of the second heat conducting plate 120. Then the second heat conducting plate 120 and the electric heating element 130 are placed in the clamping space together, and the side where the electric heating element 130 is located faces the first heat conducting plate 110. The lower edge of the second heat conducting plate 120 abuts against the clamp 210 at the bottom of the first moving group 300, and the lower part of the first moving group 300 is pulled downward according to the gravity of the second heat conducting plate 120. While the lower part of the first moving group 300 is pulled downward, the second moving group 400 is driven to fold and move through the gear 500. Until the lower edge of the first heat conducting plate 110 and the lower edge of the second heat conducting plate 120 are flush, the clamps 210 on the left and right sides move to abut against the left and right edges of the heating assembly 100. Finally, the clamp 210 on the upper part of the first moving group 300 is pressed downward on the upper edge of the heating component 100, thereby completing the positioning of the four sides of the heating component 100. After the positioning is completed, the first moving group 300 and the second moving group 400 can be locked and fixed on the first heat conducting plate 110 by screws or the like.

[0034] Further, such as Figure 4 , Figure 5 and Figure 6As shown, the bracket assembly 200 includes a guide seat 600. The guide seat 600 includes a first guide groove 610 and a second guide groove 620. The first guide groove 610 and the second guide groove 620 are cross-distributed. The first guide groove 610 extends along the moving direction of the first moving group 300. The second guide groove 620 extends along the moving direction of the second moving group 400. During installation, the first moving group 300 is slidably connected in the first guide groove 610, and the second moving group 400 is slidably connected in the second guide groove 620. The first guide groove 610 and the second guide groove 620 are used to guide the movement of the first moving group 300 and the second moving group 400 respectively. Among them, the notches of the first guide groove 610 and the second guide groove 620 can be opened toward the first heat conducting plate 110. The guide seat 600 is fixed on the first heat conducting plate 110, so as to limit the first moving group 300 and the second moving group 400 relative to the heating component 100 along the thickness direction.

[0035] In some specific embodiments of the present invention, Figure 5 , Figure 6 and Figure 8As shown, the first moving group 300 includes a first connecting plate 310 and a second connecting plate 320. The first connecting plate 310 and the second connecting plate 320 can be set to be in the shape of a long strip. A first rack surface 311 is provided on the first connecting plate 310 along the length direction, and the first rack surface 311 is meshed with the gear 500. A chuck 210 is provided on the ends of the first connecting plate 310 and the second connecting plate 320. The length directions of the first connecting plate 310 and the second connecting plate 320 are consistent. In this embodiment, the first connecting plate 310 is located at the lower side of the second connecting plate 320. A notch 111 is provided on the lower side of the first heat conducting plate 110. The lower end of the first connecting plate 310 is the chuck 210. The first connecting plate 310 performs linear translation up and down relative to the heating component 100. When the first connecting plate 310 translates upward, the chuck 210 on the first connecting plate 310 enters upward into the notch 111, and the notch 111 avoids the chuck 210 on the first connecting plate 310. When the clamp 210 on the first connecting plate 310 moves linearly, the gear 500 is driven to rotate clockwise through the first rack surface 311, and the rotation of the gear 500 drives the second moving group 400 to open, and the two clamps 210 of the second moving group 400 move in a relatively distant direction. When the clamp 210 on the first connecting plate 310 moves downward, the gear 500 is driven to rotate counterclockwise, thereby driving the second moving group 400 to contract, and the two clamps 210 on the second moving group 400 move in a relatively close direction. When the two clamps 210 of the second moving group 400 are respectively abutted against the left and right sides of the heating component 100, the two clamps 210 cannot move, thereby limiting the movement of the second moving group 400, and then limiting the first connecting plate 310 from continuing to move downward through the gear 500 and the first rack surface 311, thereby achieving a mutual limiting effect. Finally, the second connecting plate 320 is put in from top to bottom, and the clamp 210 at the upper end of the second connecting plate 320 abuts against the upper edge of the heating component 100 for positioning, and finally the second connecting plate 320 is locked on the first heat conducting plate 110 .

[0036] Further, such as Figure 3As shown, a flange 112 is provided on the edge where the notch 111 is located on the first heat conducting plate 110. In this embodiment, the notch 111 is provided on the lower side of the first heat conducting plate 110, and the flange 112 is provided on the lower side of the first heat conducting plate 110. The flange 112 is bent toward the side where the second heat conducting plate 120 is located. During the installation process, when the second heat conducting plate 120 is placed on the chuck 210 corresponding to the first connecting plate 310, the second heat conducting plate 120 pushes the first connecting plate 310 to move downward. When the second heat conducting plate 120 moves downward until its lower side edge abuts against the flange 112, the two chucks 210 on the second moving group 400 abut in place. At this time, the chuck 210 of the first connecting plate 310 and the flange 112 of the first heat conducting plate 110 are used to cooperate with each other to support the second heat conducting plate 120, so as to quickly position the lower side of the first heat conducting plate 110 and the lower side of the second heat conducting plate 120.

[0037] In some specific embodiments of the present invention, Figure 5 , Figure 6 and Figure 8 As shown, the second moving group 400 includes a first moving plate 410 and a second moving plate 420. The first moving plate 410 and the second moving plate 420 can be set in the shape of a long strip. The length directions of the first moving plate 410 and the second moving plate 420 are consistent. A second rack surface 411 is provided on the first moving plate 410 along the length direction. A third rack surface 421 is provided on the second moving plate 420 along the length direction. The second rack surface 411 and the third rack surface 421 are parallel to each other and arranged oppositely. The gear 500 is located between the second rack surface 411 and the third rack surface 421 for meshing transmission. A chuck 210 is provided on the ends of the first moving plate 410 and the second moving plate 420 that are relatively far away. In this embodiment, the first moving plate 410 and the second moving plate 420 are arranged horizontally. When the gear 500 rotates clockwise, the first moving plate 410 and the second moving plate 420 are driven to move horizontally in a relatively far-away direction through the second rack surface 411 and the third rack surface 421, and the chucks 210 on both sides are relatively far away. When the gear 500 rotates counterclockwise, the first moving plate 410 and the second moving plate 420 are driven to move laterally in a direction of approaching each other through the second rack surface 411 and the third rack surface 421 , and the clamps 210 on both sides are relatively close to each other.

[0038] In some specific embodiments of the present invention, Figure 7 and Figure 8As shown, the clamp 210 defines a U-shaped clamp 211 on the bracket assembly 200. The clamp 210 can be bent and formed on the ends of the first movable plate 410, the second movable plate 420, the first connecting plate 310 and the second connecting plate 320. The periphery of the heating component 100 is clamped in the clamp 211, and the edges of the first heat conducting plate 110 and the second heat conducting plate 120 are correspondingly positioned through the inner wall of the clamp 211, and the first heat conducting plate 110 and the second heat conducting plate 120 are limited in the thickness direction.

[0039] In some embodiments of the present invention, Figure 1 , Figure 2 and Figure 4 As shown, the bracket assembly 200 also includes a fixed seat 700. One or more fixed seats 700 can be provided. The shape of the fixed seat 700 is not limited, and can be a frame-shaped structure as shown in the figure. The fixed seat 700 is fixedly mounted on the first heat conducting plate 110, and the heating component 100 is supported by the fixed seat 700. When in use, the fixed seat 700 can be hung on a wall or other places. A third guide groove 710 is defined between the fixed seat 700 and the first heat conducting plate 110. A recessed position can be provided on the fixed seat 700, and the recessed position cooperates with the rear side of the first heat conducting plate 110 to form the third guide groove 710. The second movable group 400 is penetrated by the third guide groove 710, and the third guide groove 710 is used to further guide the second movable group 400.

[0040] In some specific embodiments of the present invention, Figure 5 , Figure 7 and Figure 8 As shown, the first moving group 300 is provided with a first limiting groove 301, and the first limiting groove 301 extends in the moving direction of the first moving group 300. The second moving group 400 is provided with a second limiting groove 302, and the second limiting groove 302 extends in the moving direction of the second moving group 400. The first heat conducting plate 110 is provided with a first limiting column 303 and a second limiting column 304. One or more first limiting columns 303 and second limiting columns 304 can be provided. The first limiting column 303 is slidably connected in the first limiting groove 301. When the first moving group 300 reciprocates, the two ends of the first limiting groove 301 can abut against the first limiting column 303, and the first limiting column 303 is used to limit the moving stroke of the first moving group 300. The second limiting column 304 is slidably connected in the second limiting groove 302. When the second moving group 400 reciprocates, both ends of the second limiting groove 302 can abut against the second limiting column 304, and the moving stroke of the second moving group 400 is limited by the second limiting column 304. According to the length and width of the heating component 100, the moving strokes of the first moving group 300 and the second moving group 400 are set accordingly, thereby achieving the effect of positioning the heating component 100 around.
