DETAILED DESCRIPTION

[0045] The following is combined with Figure 1-16 This application is described in further detail. Example

[0046] Example 1 discloses a desk with a heating function. Figure 1 , Figure 2 and Figure 3 The office desk includes a table top 1, a desktop panel 10, an electric heating film 100, a first rail 2, a second rail 20 and two support members, wherein the support members are used to support the table top 1, one of the support members includes a box body 102 and a plurality of drawers 103, and the other support member is set as a cabinet body 101.

[0047] The desktop panel 10 is fixed to the upper surface of the desktop 1. The upper surface of the desktop 1 is provided with a mounting groove 11. The bottom of the desktop 1 is provided with a through groove 12 connected to one side of the mounting groove 11. The through groove 12 is located on the side away from the office staff.

[0048] like Figure 4 , Figure 5 As shown, two first rails 2 are provided and respectively installed on the opposite side walls of the mounting groove 11, the first rails 2 are arranged horizontally, and two second rails 20 are provided and respectively installed on the opposite side walls of the through groove 12, and the angle between the second rails 20 and the first rails 2 is 110°~130°.

[0049] The track groove of the first rail 2 is connected to the track groove of the second rail 20, and the track groove of the first rail 2 is set to a wavy track groove 201. The track groove of the second rail 20 is linear. Specifically, the first rail 2 includes a strip plate 23, a plurality of first protrusions 21 and a plurality of second protrusions 22, wherein the width of the strip plate 23 is equal to the groove depth of the mounting groove 11, the strip plate 23 is fixedly connected to the groove wall of the mounting groove 11, the first protrusion 21 and the second protrusion 22 are fixed to the side of the strip plate 23, and each first protrusion 21 and each second protrusion 22 are arranged in a staggered interval along the length direction of the strip plate 23, the first protrusion 21 is higher than the second protrusion 22, and the first protrusion 21 and the second protrusion 22 are both provided with arc surfaces, and each arc surface constitutes the wavy track groove 201.

[0050] like Figure 6 As shown, the side edges of the electric heating film 100 are slidably matched with the wavy track groove 201 of the first track 2 and the track groove of the second track 20, respectively, and since there is a gap between two adjacent first protrusions 21 and a gap between two adjacent second protrusions 22, the crests and troughs of the wavy electric heating film 100 can respectively abut against the lower surface of the desktop panel 10 and the bottom of the mounting groove 11.

[0051] In this way, by providing the wavy rail groove 201 to limit the electric heating film 100 to be wavy, the wavy electric heating film 100 has a larger heating area than the flat electric heating film 100 under the same desktop area, thereby greatly improving the heat generation per unit desktop area.

[0052] One side of the electric heating film 100 has a connection terminal 104, and the bottom of the table top 1 is embedded with a connection box 105, which is located on one side of the notch of the through slot 12. The connection terminal 104 is electrically connected to the circuit board arranged in the connection box 105 to realize power supply to the electric heating film 100.

[0053] Furthermore, in order to reduce the heat loss in the installation groove 11 , a rubber strip (not shown in the figure) may be embedded in the notch of the through groove 12 , so that the through groove 12 and the installation groove 11 form a closed space.

[0054] In addition, in order to facilitate the subsequent maintenance and replacement of the electric heating film 100, the following settings are also made. The office desk also includes a traction component 3, which is used to apply traction force to the electric heating film 100 to drive the electric heating film 100 to move along the wavy rail groove 201, thereby reducing the bending deformation of the electric heating film 100 in the hard plugging mode, so as to ensure that the electric heating film 100 can move smoothly along the wavy rail groove 201 and ensure that the electric heating film 100 maintains a wavy state.

[0055] Specifically, Figure 4 , Figure 7As shown, the traction assembly 3 includes a rubber roller 31, a first gear 311, a second gear 32, a worm wheel 321 and a worm 322, wherein the rubber roller 31 is horizontally perpendicular to the first rail 2, and two rubber rollers 31 are provided and arranged up and down. The two rubber rollers 31 are used to clamp the electric heating film 100 together. A rotating shaft 312 is fixed to the end of the rubber roller 31, and the rotating shaft 312 passes through the connection between the first rail 2 and the second rail 20, so that the rubber roller 31 can rotate relative to the first rail 2.

[0056] The groove wall of the through groove 12 is also recessed to provide a groove body (not shown in the figure), and the first gear 311, the second gear 32, the worm wheel 321 and the worm 322 are all located in the groove body, wherein the first gear 311 is fixed to the rotating shaft 312, the two first gears 311 are meshed with each other, the second gear 32 is rotatably connected to the groove wall of the groove body, the second gear 32 is larger than the first gear 311, the second gear 32 is meshed with one of the first gears 311, the worm wheel 321 is coaxially fixed with the second gear 32, the worm 322 is rotatably connected to the groove wall of the groove body, and the worm 322 is meshed with the worm wheel 321, and at the same time, one end of the worm 322 is exposed through the groove opening of the through groove 12.

[0057] When a new electric heating film 100 needs to be replaced, first disconnect the connection between the terminal 104 and the junction box 105 of the old electric heating film 100, and then pull the old electric heating film 100 out of the installation groove 11 and the through groove 12 (need to overcome a large friction force) to complete the disassembly of the old electric heating film 100; then put one side of the new electric heating film 100 through the through groove 12, and when one side of the electric heating film 100 moves along the track groove of the second rail 20 to between the two rubber rollers 31, the rubber rollers 31 clamp one side of the electric heating film 100. , and then rotate the worm 322, the worm 322 drives the worm wheel 321 and the second gear 32 to rotate, thereby driving the two first gears 311 to rotate. Since the two rubber rollers 31 rotate in opposite directions, the friction force of the rubber rollers 31 will drive the electric heating film 100 to move continuously, so that the electric heating film 100 can move along the wavy track groove 201 of the first track 2, that is, the friction driving force of the rubber roller 31 overcomes the friction resistance of the wavy track groove 201 to the electric heating film 100, so as to ensure that the electric heating film 100 can be arranged in a wavy shape. Example

[0058] The difference between Example 2 and Example 1 is that Figure 8 As shown, the desktop panel 10 is embedded with multiple copper wires 111, the diameter of the copper wire 111 is 1-2 mm, and the upper and lower ends of the copper wire 111 are flush with the upper and lower surfaces of the desktop panel 10 respectively. Since the copper wire 111 has good thermal conductivity, the heat of the installation slot 11 can be transferred more directly to the surface of the desktop panel 10. Example

[0059] The difference between Example 3 and Example 1 is that Fig. 9 As shown, a plurality of protrusions 313 are integrally formed on the surface of the rubber roller 31 . The protrusions 313 are divided into two groups. The plurality of protrusions 313 in one group are arranged spirally around the axis of the rubber roller 31 . The rotation directions of the two groups of spirally arranged protrusions 313 are opposite.

[0060] When the rubber roller 31 drives the electric heating film 100 to move along the wave track 201, the two groups of spirally arranged protrusions 313 apply force components along the axial direction of the rubber roller 31 and in opposite directions to the electric heating film 100 respectively. The two axially opposite force components will force the electric heating film 100 to be axially tensioned, so that it has tension, making it less likely to be obstructed and wrinkled and deformed during the movement of the electric heating film 100 along the wave track 201. At the same time, the electric heating film 100 with tension maintains a better shape and can move relatively smoothly along the wave track 201, which is easy to operate. Example

[0061] The difference between Example 4 and Example 1 is that Fig.10 , Fig.11 As shown, the traction assembly 3 includes a traction rope 34 and a fixing rod 33, and the fixing rod 33 includes a semicircular first half rod 331 and a second half rod 332. The cross-sections of the first half rod 331 and the second half rod 332 are both semicircular. The first half rod 331 fixes the buckle 333, and the second half rod 332 is provided with a buckle groove 334 for the buckle 333 to be inserted into. One side of the electric heating film 100 is provided with a through hole 106 for the buckle 333 to pass through. During installation, the first half rod 331 and the second half rod 332 clamp the electric heating film 100 at the same time. During installation, the buckle 333 passes through the through hole 106 and is buckled with the buckle groove 334 to achieve fixation between the fixing rod 33 and the electric heating film 100.

[0062] A vertical threading hole 112 is provided at the bottom of the table top 1 , the upper end of the threading hole 112 is connected to a side of the mounting groove 11 away from the through groove 12 , and a guide wheel 114 is provided at a position above the threading hole 112 of the mounting groove 11 .

[0063] The lower end of the threading hole 112 is threadedly connected with an end cover 113 to close the threading hole 112 . One end of the traction rope 34 is fixed to the fixing rod 33 , and the other end of the traction rope 34 passes around the guide wheel 114 and is fixed to the end cover 113 .

[0064] When it is necessary to replace the new electric heating film 100, first press the exposed side of the old electric heating film 100 located at the through groove 12 to pull the old electric heating film 100 out of the installation groove 11 (the traction rope 34 is in a relaxed state and the traction rope 34 is still located in the installation groove 11), then remove the fixing rod 33 on the old electric heating film 100, install the fixing rod 33 on one side of the new electric heating film 100, then loosen the end cover 113, and pull the end cover 113 downward to pull the traction rope 34, the traction rope 34 drives the fixing rod 33 to move along the track groove of the second rail 20 and the wavy track groove 201 of the first rail 2 in sequence, so as to drive the electric heating film 100 to move along the wavy track groove 201, that is, the pulling force of the traction rope 34 overcomes the friction resistance of the wavy track groove 201 to the electric heating film 100, so as to ensure that the electric heating film 100 can be arranged in a wavy shape, which is convenient and quick. Example

[0065] The difference between Example 5 and Example 4 is that Fig.12 , Fig.13 , Fig.14 As shown, the first protrusion 21 and the second protrusion 22 are separately arranged from the strip plate 23, specifically, the side of the strip plate 23 is provided with a vertical slide groove 232 corresponding to the first protrusion 21 and the second protrusion 22, and the first protrusion 21 and the second protrusion 22 are both provided with a slider 24, and the slider 24 slides with the slide groove 232. The spring 25 is located in the slide groove 232, and the spring 25 corresponding to the first protrusion 21 is used to force the first protrusion 21 to move up, and the spring 25 corresponding to the second protrusion 22 is used to force the second protrusion 22 to move down, that is, the elastic force of the spring 25 makes the first protrusion 21 and the second protrusion 22 move away from each other, so as to increase the width of the wave track groove 201, so as to reduce the difficulty of the electric heating film 100 entering the wave track groove 201, and the electric heating film 100 is easier to move along the wave track groove 201 while making a smaller degree of wave deformation.

[0066] A first guide surface 241 is provided at one end of the slider 24 away from the spring 25 .

[0067] Two parallel plates 26 are fixed to one end of the strip plate 23 near the threading hole 112, and the gap between the plates 26 is connected to the end of the wave track groove 201. When the fixing rod 33 moves to the end of the wave track groove 201, it will enter the gap between the two plates 26 to move horizontally.

[0068] The traction assembly 3 also includes a linkage structure, which includes two slide bars 35. The upper and lower parts of the side surfaces of the strip plate 23 are provided with strip grooves 231. The strip grooves 231 are arranged to penetrate along the length direction of the strip plate 23. The strip grooves 231 are connected to the slide bars 232. The slide bars 35 are slidably connected to the strip grooves 231. One ends of the two slide bars 35 are commonly connected to a connecting plate 351.

[0069] The slide bar 35 is fixed with a plurality of wedge blocks 36 which are arranged in one-to-one correspondence with the sliders 24 . The wedge blocks 36 have a second guide surface 361 . The second guide surface 361 is used to cooperate with the first guide surface 241 .

[0070] When the fixing rod 33 slides to the end position of the mounting groove 11 (the fixing rod 33 drives the electric heating film 100 to completely enter the wave rail groove 201), the fixing rod 33 abuts against the connecting plate 351 to drive the sliding bar 35 to slide. At this time, the second guide surface 361 of the wedge block 36 cooperates with the first guide surface 241 of the slider 24 to force the slider 24 to slide toward the spring 25, that is, drives the first protrusion 21 to move downward and drives the second protrusion 22 to move upward. The first protrusion 21 forces the trough of the electric heating film 100 to abut against the bottom of the mounting groove 11, and the second protrusion 22 forces the peak of the electric heating film 100 to abut against the lower surface of the desktop plate 10, thereby making the shape of the electric heating film 100 in the mounting groove 11 more compact, the position stability of the electric heating film 100 is strong, the heat per unit area is large, and the electric heating film 100 can stably divide the inner cavity of the mounting groove 11 into multiple independent chambers, reduce heat loss, and heat up faster.

[0071] At this time, the traction rope 34 is in a stretched state, and then part of the structure of the traction rope 34 is clamped in the threaded matching position between the end cover 113 and the threading hole 112, that is, the threaded matching of the end cover 113 is used to clamp the traction rope 34 to reduce the occurrence of the spring 25 being reset due to the relaxation of the traction rope 34. Example

[0072] The difference between Example 6 and Example 5 is that Fig.15 , Fig.16 As shown, the electric heating film 100 is provided with ventilation holes 107 , and the ventilation holes 107 are provided in plurality. The ventilation holes 107 are located between the crests and troughs of the electric heating film 100 , and two adjacent ventilation holes 107 are staggered.

[0073] A vertical air inlet 13 is provided at the bottom of the table top 1. The air inlet 13 is located on the side close to the office personnel. The upper end of the air inlet 13 is connected to the side of the installation slot 11 away from the through slot 12. A fan 14 is provided at the lower end of the air inlet 13. A sliding cover 108 is provided at the slot opening of the through slot 12. The sliding cover 108 is slidably provided to open and close the slot opening of the through slot 12.

[0074] When it is necessary to blow hot air to the feet of office workers, the slot of the through slot 12 can be opened, and then the fan 14 can be started. The external wind is drawn into the air inlet 13 from the side close to the office worker, and then passes through the mounting slot 11. In this process, the wind is heated into hot air by the electric heating film 100. Since the crests and troughs of the electric heating film 100 are respectively in contact with the bottom of the mounting slot 11 and the lower surface of the desktop panel 10, the electric heating film 100 divides the inner cavity of the mounting slot 11 into a plurality of non-connected chambers, and the ventilation holes 107 are staggered, so that the wind can move in a circuitous manner in a plurality of chambers through the ventilation holes 107 to efficiently heat and form hot air. The hot air then flows downward obliquely through the slot of the through slot 12 in the open state to blow to the position of the feet of the office worker to heat the feet of the office worker, so as to further improve the office comfort.

[0075] Furthermore, the air inlet 13 is located on a side close to the office personnel, thereby forming a drainage to drive the hot air discharged from the through slot 12 to move in a direction close to the office personnel, so as to further improve the utilization rate of the hot air.

[0076] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
