[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0027] like Figures 1-5 As shown, this utility model provides a smoke frame blocking device, which is installed on the inner wall of the housing and the inner wall of the door of a vacuum dehumidifier to separate the smoke frame from the inner wall of the housing by a certain distance. The smoke frame blocking device includes a mounting base 1, a fixed sleeve 2, a movable part 3, an elastic part 4, and a contact assembly 5. The mounting base 1 is used to fix and connect to the inner wall of the housing or the inner wall of the door, and the connection method can be welding or bolting. The fixed sleeve 2 is fixedly mounted on the mounting base 1, and the fixed sleeve 2 and the mounting base 1 can be fixedly connected by welding or bolting. The fixed sleeve 2 has a stepped hole that extends through the fixed sleeve 2 along its axis. The end of the fixed sleeve 2 near the mounting base 1 has a larger hole of the stepped hole, and the end of the fixed sleeve 2 away from the mounting base 1 has a smaller hole of the stepped hole. At least a portion of the movable part 3 is disposed in the stepped hole, and the movable part 3 slides in contact with the wall of the stepped hole. The elastic element 4 is disposed within the stepped hole, with its two ends abutting against the mounting base 1 and the movable element 3, respectively. The elastic element 4 is used to slide the movable element 3 away from the mounting base 1. The contact component 5 is installed at the end of the movable element 3 away from the mounting base 1, and is used to contact the tobacco frame. The tobacco frame blocking device uses a fixed sleeve 2 and a movable element 3 in sliding engagement. The contact component 5 is positioned at the end of the movable element 3 away from the mounting base 1 to contact the tobacco frame, creating a certain gap between the tobacco frame and the inner wall of the vacuum rehumidifier chamber, preventing condensate from flowing along the tobacco frame onto the tobacco leaves during its descent. Furthermore, the elastic element 4 is positioned between the movable element 3 and the mounting base 1 to buffer the contact component 5 during contact with the tobacco frame, reducing the impact force of the contact component 5 on the tobacco frame.
[0028] Furthermore, a limiting flange 31 is provided at the end of the movable part 3 near the mounting base 1. The limiting flange 31 mates with the wall of the large hole of the stepped hole, and the stepped structure 21 of the stepped hole is used to restrict the limiting flange 31 from dislodging from the stepped hole. Thus, the movable part 3 is limited in the sliding direction by the mounting base 1 and the stepped structure 21 of the stepped hole, respectively, to prevent the movable part 3 from dislodging from the fixed sleeve 2.
[0029] Optionally, in this embodiment, the elastic element 4 can be a helical spring or a butterfly spring. In this embodiment, the elastic element 4 is preferably a helical spring, which is located inside the large hole of the stepped hole and is coaxial with the stepped hole. After the fixing sleeve 2 is fixedly installed on the mounting base 1, the two ends of the helical spring abut against the mounting base 1 and the movable element 3 respectively, thereby pushing the movable element 3 to slide away from the mounting base 1.
[0030] Specifically, the contact component 5 includes a connector 51 and a contact head 52. The connector 51 is fixedly connected to the movable part 3, and the contact head 52 is fixedly mounted on the connector 51 for contacting the cigarette frame. The connector 51 and the movable part 3 can be connected by welding, bonding, or threading, and the contact head 52 is fixedly connected to the connector 51 by bonding. In this embodiment, the movable part 3 has a threaded hole at the end away from the mounting base 1, and the connector 51 is threadedly connected to the movable part 3 through the threaded hole. The contact head 52 is made of nylon or rubber and can provide cushioning protection when in contact with the cigarette frame to avoid damage to the cigarette frame.
[0031] Specifically, when using the smoke frame blocking device in this embodiment, the contact component 5 is threadedly connected to the movable part 3. Then, one end of the movable part 3 connected to the contact component 5 is inserted through the large hole of the stepped hole in the fixed sleeve 2, and then the helical spring is placed into the large hole of the stepped hole. The end of the fixed sleeve 2 with the large hole of the stepped hole is welded or bolted to the mounting base 1. Finally, the mounting base 1 is installed on the inner wall of the vacuum dehumidifier's housing or the inner wall of the door. After the smoke frame enters the vacuum dehumidifier's housing, the door is closed. The smoke frame blocking device creates a certain gap between the smoke frame and the inner wall of the housing and the inner wall of the door, preventing condensate from flowing along the smoke frame onto the tobacco leaves.
[0032] Optionally, such as Figures 3-5 As shown, a guide groove can also be provided on the outside of the fixed sleeve 2. The guide groove guides the condensate, so that the condensate flows directly downwards as it flows outside the fixed sleeve 2, reducing the amount of condensate flowing along the fixed sleeve 2 to the smoke frame. The guide groove can be an annular groove 22 or a spiral groove 23.
[0033] Specifically, such as Figure 3 As shown, when the guide groove is set as an annular groove 22, multiple annular grooves 22 are provided on the outside of the fixed sleeve 2. The multiple annular grooves 22 are spaced apart along the axial direction of the fixed sleeve 2. Each guide groove can guide the flowing condensate water, further reducing the amount of condensate water flowing to the smoke frame along the fixed sleeve 2.
[0034] Specifically, such as Figures 4-5As shown, when the guide groove is set as a spiral groove 23, the outside of the fixed sleeve 2 is provided with a spiral groove 23, which can also reduce the amount of condensate flowing along the fixed sleeve 2 to the smoke frame. The spiral groove 23 includes a starting end 231 and a ending end 232. The starting end 231 of the spiral groove 23 is spaced apart from the end face of one end of the fixed sleeve 2, and the ending end 232 of the spiral groove 23 is spaced apart from the end face of the other end of the fixed sleeve 2. That is, the spiral groove 23 is entirely located on the outside of the fixed sleeve 2 and is not connected to the two end faces of the fixed sleeve 2, thus preventing condensate from flowing along the spiral groove 23 to the smoke frame.
[0035] This embodiment provides a vacuum dehumidifier, which includes a housing and a smoke frame blocking device as described in this embodiment. The mounting base 1 of the smoke frame blocking device is installed on the inner side wall of the housing and the inner side wall of the door. The installation position of the smoke frame blocking device on the inner side wall of the housing and the inner side wall of the door is determined according to the size of the smoke frame. Specifically, after the smoke frame blocking device is installed on the inner side wall of the housing or the inner side wall of the door, the height of the contact position with the smoke frame from the bottom of the smoke frame is greater than the height from the top of the smoke frame, that is, it is closer to the bottom of the smoke frame to avoid abnormal postures such as smoke frame displacement, flipping, or even tilting.
[0036] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
