[0019] See also Figures 1 to 4 A dust-proof device for a moisture-replenishing machine includes a top cover 10 and a cover curtain 20. The top cover 10 includes a top plate 11, a cover plate 12 and side plates 13. The top plate 11 is fixedly arranged on the top of a vibration groove 30. The cover plate 12 is hingedly connected to the top plate 11. The side plates 13 are arranged on both sides of the cover plate 12. The cover curtain 20 is arranged at the bottom of the side plate 13. The top cover 10 has a closed state and an open state. In the closed state, the cover plate 12 is placed on the top of the vibration groove 30, the cover plate 12 is in contact with the vibration groove 30, the cover curtain 20 is located outside the two side walls of the vibration groove 30, and the cover plate 12 is connected to the vibration groove 30 to form a channel for the movement of the tobacco block. Under the stop of the cover plate 12 and the cover curtain 20, the tobacco powder produced by the pressed block during the vibration process is confined in the channel to prevent the tobacco powder from overflowing; in the open state, the cover plate 12 is separated from the vibration groove 30, and the top of the vibration groove 30 is exposed, which is convenient for the staff to clean the inside of the vibration groove 30 and the top cover 10. The cover plate 12 can rotate relative to the top plate 11 to switch it between the open state and the closed state.

[0020] The top plate 11 is used to provide a rotation fulcrum for the cover plate 12. The top plate 11 is fixedly arranged on the top of the vibration groove 30. Preferably, the two ends of the top plate 11 are respectively in contact with the top of the two side walls of the vibration groove 30, so that the top plate 11 is placed horizontally on the vibration groove 30 and completely covers the vibration groove 30. A hinge is arranged on the side of the top plate 11, and the hinge is connected to the side of the cover plate 12 so that the cover plate 12 can rotate relative to the top plate 11. The cover plate 12 is a flat plate, and the hinge is arranged close to the top surface of the vibration groove 30, so that in the closed state, the cover plate 12 and the top surfaces of the two side walls of the vibration groove 30 are in surface contact, and the cover plate 12 can completely cover the top of the vibration groove 30. There is no gap between the cover plate 12 and the top surface of the vibration groove 30, thereby improving the dustproof performance of the cover plate 12.

[0021] Preferably, the specifications of the hinge should satisfy the requirement that its maximum opening angle is greater than 90 degrees, so that when in the open state, the cover 12 can be flipped over the top plate 11, and the cover 12 can be stabilized above the top plate 11 by its own gravity and can be maintained in the open state without a fixed structure, thereby facilitating the cleaning of the vibration groove 30.

[0022] Side panels 13 are provided on both sides of the cover plate 12, and a cover curtain 20 is provided at the bottom of the side panels 13. When the cover plate 12 is in a closed state, the cover curtain 20 is located outside the side wall of the vibration groove 30, forming a stopper on both sides of the vibration groove 30 to prevent smoke from escaping. The width of the cover plate 12 should be sufficient so that the cover curtain 20 is always located outside the side wall of the vibration groove 30 regardless of whether it is in an open state or a closed state.

[0023] Preferably, the side panel 13 includes a mounting plate 131 and a connecting plate 132 which are vertically connected. The mounting plate 131 is used to connect the cover plate 12, and the connecting plate 132 is used to connect the cover curtain 20. A waist-shaped hole 133 is provided on the mounting plate 131, and the length direction of the waist-shaped hole 133 is parallel to the width direction of the vibration groove 30. The side panel 13 is connected to the side edge of the cover plate 12 through the waist-shaped hole 133. The side panel 13 and the connection position of the cover plate 12 can be moved along the length direction of the waist-shaped hole 133 to adjust the distance between the connecting plate 132 and the side wall of the vibration groove 30, so that when in a closed state, the cover plate 12 is close to the outer side of the side wall of the vibration groove 30 to improve the blocking effect of the cover curtain 20 on the smoke.

[0024] Preferably, in this embodiment, the cover curtain 20 is a rubber soft curtain, which has a certain deadweight and can be kept in a vertical state in the closed state. During the operation of the vibration groove 30, the vibration of the vibration groove 30 has a low influence on the deformation of the cover curtain 20, and the cover curtain 20 can be kept close to the side wall of the vibration groove 30 to improve the dustproof effect. Furthermore, in order to further improve the dustproof effect of the cover curtain 20, a limit strip 21 is provided on the side of the cover curtain 20 close to the vibration groove 30. In actual production, a curling edge 31 bent outward is provided on the top of the side wall of the vibration groove 30. The curling edge 31 can avoid safety problems such as accidental injury to the tip of the top of the vibration groove 30 during the production process. At the same time, the surface formed by the curling edge 31 on the top of the vibration groove 30 can be used to set up other devices to improve the flexibility of the use of the vibration groove 30. When the top cover 10 is in the closed state, the limit strip 21 is parallel to the curling edge 31 and is located below the curling edge 31. When the vibration groove 30 vibrates and the cover curtain 20 is vibrated upward, the limit strip 21 can contact with the curling edge 31, thereby limiting the movement of the cover curtain 20 and preventing the cover curtain 20 from being displaced a large distance.

[0025] It should be noted that since the cover curtain 20 is a soft rubber curtain, during the process of changing from a closed state to an open state, the cover curtain 20 can be manually folded outward to make the limit strip 21 flip to the outside of the cover curtain 20, thereby avoiding the limit strip 21 from contacting the rolled edge 31 of the vibration groove 30 during the conversion process and affecting the rotation of the cover plate 12.

[0026] The cover curtain 20 is in sheet shape. In this embodiment, the cover curtain 20 is fixed to the lower end of the connecting plate 132 by the pressing plate 14. The length of the pressing plate 14 is consistent with the length of the connecting plate 132. The pressing plate 14 is fixed to the connecting plate 132 by screws, and the cover curtain 20 is sandwiched between the pressing plate 14 and the connecting plate 132. The upper end of the cover curtain 20 is pressed on the connecting plate 132 by processing the pressing plate 14 to increase the sealing of the connection between the cover curtain 20 and the connecting plate 132, and avoid the existence of a gap between the cover curtain 20 and the connecting plate 132.

[0027] Furthermore, a reinforcing rib 121 is provided on the cover plate 12 , and the reinforcing rib 121 is arranged across the cover plate 12 to prevent the middle portion of the cover plate 12 from bending and deforming.

[0028] In this embodiment, the device is arranged at the entrance of the rehumidifier, which is higher than the top of the vibration trough 30. Therefore, in order to adapt to the structure of the entrance of the rehumidifier and the structure of the vibration trough 30, the top plate 11 and the cover plate 12 completely cover the entrance of the rehumidifier and the top of the vibration trough 30. The top plate 11 has a certain slope, such as Figure 1 It should be noted that even if the top plate 11 is tilted relative to the top of the vibration groove 30, since the cover plate 12 and the top plate 11 are hingedly connected, the tilt of the top plate 11 does not affect the cover plate 12 from completely covering the vibration groove 30. As long as the hinge between the top plate 11 and the cover plate 12 is close to the top of the vibration groove 30, the cover plate 12 can be placed on the vibration groove 30 by rotation. As another embodiment, the top plate 11 can be set in contact with the top of the vibration groove 30, such as Figure 3 and Figure 4 shown.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model.
