[0027] Reference Figure 1-5 As shown, this embodiment discloses a controllable negative pressure heating drying device for carpets, including a dryer 1, a plurality of buttons 2 fixedly connected to the surface of the dryer 1, a filter 3 fixedly connected to one side of the dryer 1, a cleaning device 4 is provided on one side of the dryer 1, and a protective device 5 is provided at the position of the dryer 1 corresponding to the button 2.
[0028] Reference Figure 1-5As shown, the cleaning device 4 includes a servo motor 41, which is fixedly connected to one side of the dryer 1. The output end of the dryer 1 is fixedly connected to a screw 42, and one end of the screw 42 is provided with a pad 43. The pad 43 is fixedly connected to the dryer 1. The arc surface of the screw 42 is threadedly connected to a movable plate 44. The side of the movable plate 44 close to the filter 3 is fixedly connected to a plurality of bristles 45. The bristles 45 are equally divided into two groups. The cross-sections of the two groups of bristles 45 are in the shape of a hook, and the bristles 45 fit the filter 3. When the filter 3 on one side of the dryer 1 needs to be cleaned, the staff turns on the servo motor 41, and the servo motor 41 drives the screw 42 to rotate, and the screw 42 drives the movable plate 44 and the brush 45 to move together. The hooked tips of the brush 45 are inserted into the holes of the filter 3 and the dust in the holes is brought out of the filter 3. The brush 45 provided by the cleaning device 4 achieves the effect of cleaning the filter 3, preventing the dust from clogging the filter 3, thereby affecting the normal heat dissipation of the dryer 1 and reducing the service life of the dryer 1.
[0029] Reference Figure 1-5 As shown, a limit rod 49 is slidably inserted into one side of the movable plate 44. Both ends of the limit rod 49 are fixedly connected to the dryer 1. The limit rod 49 effectively limits the movement direction of the movable plate 44, preventing it from rotating and improving the stability of its movement. A bearing 48 is provided on the surface of the backing plate 43. The outer ring of the bearing 48 is fixedly connected to the backing plate 43, and the inner ring of the bearing 48 is fixedly connected to the screw 42. The bearing 48 improves the rotational stability of the screw 42 and prevents it from shaking. A reserved hole 47 is provided on the surface of the movable plate 44. A collection box 46 is slidably inserted into the movable plate 44 through the reserved hole 47. The collection box 46 is located directly below the brush 45. Before using the brush 45 to clean the filter 3, the staff member moves the collection box 46 and inserts it into the reserved hole 47 of the movable plate 44. The collection box 46 collects the dust removed by the brush 45.
[0030] Reference Figure 1-5As shown, the protective device 5 includes two slide rails 51, which are fixedly connected to the dryer 1. The two slide rails 51 are respectively located on both sides of several buttons 2. Slide plates 52 are slidably inserted into the inner walls of the slide rails 51. A protective plate 53 is fixedly connected to the side of the two slide plates 52 that are close to each other. A counterweight 56 is fixedly connected to the surface of the protective plate 53. The bottom of the two slide rails 51 is fixedly connected to the same bottom plate 54. When it is necessary to use the button 2, the staff first moves the protective plate 53. The protective plate 53 moves with the slide plates 52 in the slide rails 51. When the button 2 under the protective plate 53 is exposed, the staff operates the button 2. After the operation is completed, the protective plate 53 is released. Under the action of the weight of the counterweight 56, the protective plate 53 moves to the position of the bottom plate 54, covering the button 2. The protective device 5 achieves the effect of protecting the button 2, preventing the staff from accidentally touching the button 2, thereby affecting the normal drying of the carpet.
[0031] Reference Figure 1-5 As shown, a pull plate 57 is fixedly attached to the surface of the protective plate 53, and the surface of the pull plate 57 is provided with anti-slip grooves. The provision of the pull plate 57 facilitates the movement of the protective plate 53, providing convenience for the staff. A rubber pad 55 is fixedly attached to the upper surface of the bottom plate 54, and is located directly below the protective plate 53. The provision of the rubber pad 55 protects the protective plate 53 and prevents damage.
[0032] Working principle: before using the brush 45 to clean the filter 3, the staff moves the collection box 46 and inserts the collection box 46 into the reserved hole 47 of the movable plate 44 to install the collection box 46. When it is necessary to clean the filter 3 on one side of the dryer 1, the staff turns on the servo motor 41, and the servo motor 41 rotates the screw 42. The bearing 48 on the pad 43 improves the stability of the rotation of the screw 42. The screw 42 moves with the movable plate 44 and the brush 45. The hooked tip of the brush 45 is inserted into the hole of the filter 3 and brings the dust in the hole out of the filter 3. The dust falls into the collection box 46, which is convenient for the staff to dump it uniformly later. The brush 45 set by the cleaning device 4 achieves the effect of cleaning the filter 3, preventing dust from blocking the filter 3, thereby affecting the normal heat dissipation of the dryer 1 and reducing the service life of the dryer 1.
[0033] When the button 2 needs to be used, the staff first moves the protective plate 53 by pulling the plate 57. The protective plate 53 moves with the slide plate 52 in the slide rail 51. When the button 2 under the protective plate 53 is exposed, the staff operates the button 2. After the operation, the protective plate 53 is released. Under the action of the gravity of the counterweight block 56, the protective plate 53 moves to the position of the bottom plate 54. The protective plate 53 fits with the rubber pad 55. The protective plate 53 covers the button 2. The protective device 5 achieves the effect of protecting the button 2, preventing the staff from accidentally touching the button 2, thereby affecting the normal drying of the carpet.
