[0002] Observation windows are often used to monitor the internal production of closed containers during operation. These windows can be made of either ordinary glass or transparent plexiglass. During tobacco processing in tobacco drying machines, tobacco foam and dust often contaminate the observation windows, obstructing operators' ability to see inside the equipment. Therefore, a cleaning device is required for these windows. Currently, these cleaning devices are typically manually operated, which is laborious and requires repeated manual cleaning after a period of time, making automated, scheduled cleaning impossible.

[0003] For example, the prior art Chinese patent CN202320272509.6 includes a glass cleaner, a rotating shaft and a rotating handle. It drives the glass cleaner installed inside the circular glass observation window to the inside of the observation window by rotating the external rotating handle, which has the above-mentioned technical problems.

[0004] Therefore, a better observation window cleaning device is needed to improve the above problems. Utility Model Content

[0027] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0028] Please refer to Figure 1-3 Some embodiments of the present application provide an observation window cleaning device, including: a rotating member 1, a cleaning member 2, an electric driving member 3 and a switch module; the rotating member 1 is arranged through the observation window 100; the cleaning member 2 is connected to the rotating member 1 and contacts the inner side of the observation window 100, and can be rotated relative to the observation window 100 to clean the observation window 100; the electric driving member 3 is connected to the rotating member 1 and is arranged on the outside of the observation window 100, and can drive the rotating member 1 to rotate; the switch module is electrically connected to the electric driving member 3, and controls the operation of the electric driving member 3.

[0029] When the observation window 100 needs to be cleaned, the switch module sends a signal to activate the electric drive member 3, which drives the rotating member 1 to drive the cleaning member 2 to rotate relative to the observation window 100, thereby cleaning and removing obstructions on the inside of the observation window 100 that obstruct the view.

[0030] The implementation method of the switch module is not limited; for example, it may include a manual switch or be connected to a sensor signal in the prior art. Considering that in some application scenarios, excessive or prolonged retention of obstructions on the observation window 100 may make cleaning difficult or result in poor cleaning results, in some embodiments, the present application further includes a control module and a timing unit connected to the control module. The control module is signal-connected to the switch module, and the control module controls the switch module to activate the electric drive 3 at preset intervals. By periodically cleaning the obstructions at preset intervals, the amount and duration of the obstructions on the observation window 100 can be controlled.

[0031] Considering the potential failure scenarios of the electric drive member 3, such as power outages, downtime for maintenance, or damage, in some embodiments, the present application further includes a manual drive member 4, which is in transmission connection with the rotating member 1 and can drive the rotating member 1 to rotate. Preferably, considering that manual drive is a backup drive solution for electric drive, in some embodiments, the manual drive member 4 is detachably connected to the rotating member 1. For example, the manual drive member 4 is in transmission connection with the rotating member 1 through threaded connections, plug-in connections, etc., and is installed only when manual drive is required.

[0032] The implementation of the electric drive member 3 and the manual drive member 4 is not limited. As a specific solution, in some embodiments, the electric drive member 3 is a double-ended motor. The double-ended motor includes a drive shaft with loads connectable at both ends. One end of the drive shaft is connected to the rotating member 1, and the other end is connected to the manual drive member 4. Manually rotating the manual drive member 4 drives the drive shaft of the double-ended motor, which in turn transmits power to the rotating member 1. This implementation of the electric drive member 3 and the manual drive member 4 is relatively simple and efficient.

[0033] In some embodiments, the rotating member 1 includes a connecting ring 11 and a rotating shaft 12. The connecting ring 11 is fixedly disposed on both sides of the observation window 100, and the rotating shaft 12 is rotatably disposed within the connecting ring 11. A limiting ring groove 111 is provided on a side of the connecting ring 11 close to the cleaning member 2, and a limiting block 112 is provided on the rotating shaft 12 that can slide within the limiting ring groove 111. The cleaning member 2 often removes obstructions by scraping or sweeping, so it will be subject to reaction forces in different directions during cleaning. The provision of the limiting ring groove 111 and the limiting block 112 can limit the movement of the cleaning member 2, thereby improving the movement accuracy and reducing the possibility of damage to the device.

[0034] The cleaning member 2 is often used to remove obstructions by scraping or sweeping, so the cleaning member 2 is often a consumable. In some embodiments, the cleaning member 2 includes a connecting block 21 and a cleaning rod 22, and the cleaning rod 22 is detachably connected to the connecting block 21. Implementing the cleaning member 2 in this manner facilitates replacement and saves costs by avoiding the need to replace components such as the connecting block 21.

[0035] In some embodiments, a cleaning brush is provided on the side of the cleaning rod 22 near the observation window 100. The cleaning brush has less friction with the observation window 100 and has a longer lifespan than rubber erasers, electrostatic erasers, etc., and is particularly suitable for obstructions with relatively dry and large particles, such as tobacco foam.

[0036] The present application also provides an observation window 100 on which the above-mentioned observation window cleaning device is provided, with all its beneficial effects.

[0037] The present application also provides a tobacco dryer, which is provided with the above-mentioned observation window 100, wherein the observation window is used to observe the drying condition of the tobacco, and the observation window cleaning device is used to clean the tobacco foam.

[0038] The following combination Figure 1-3 A specific embodiment of an observation window cleaning device is listed below:

[0039] The invention comprises a rotating member 1, a cleaning member 2, an electric drive member 3, and a switch module. The rotating member 1 comprises a connecting ring 11 and a rotating shaft 12. The connecting ring 11 is fixedly mounted on both sides of an observation window 100. The rotating shaft 12 is rotatably mounted within the connecting ring 11, with one end threadedly connected to the electric drive member 3 and the other end threadedly connected to the cleaning member 2. The surface of the connecting ring 11 near the cleaning member 2 is provided with a retaining ring groove 111. The rotating shaft 12 is provided with a retaining block 112. When the rotating shaft 12 rotates, the retaining block 112 can slide and abut against the retaining ring groove 111 to limit the position of the rotating shaft 12. The cleaning member 2 comprises a connecting block 21 and a cleaning rod 22. The cleaning rod 22 is threadedly connected to the connecting block 21. The side of the cleaning rod 22 near the observation window 100 is a cleaning brush. The electric drive member 3 is a double-headed motor, comprising a transmission shaft with threads at both ends. One end of the transmission shaft is threadedly connected to the rotating member 1 and the other end is threadedly connected to the manual drive member 4. The switch module includes a manual switch, which can cause the electric drive member 3 to rotate when the switch is turned on.

[0040] It also includes a control module and a timing unit connected to the control module. The control module is signal-connected to the switch module. The control module controls the switch module to operate the electric drive component 3 at preset intervals.

[0041] The motor further comprises a manual drive member 4 , which is specifically a handle that can be threadedly connected to one end of the double-headed motor away from the rotating member 1 .

[0042] During operation, the timing unit automatically controls the electric drive 3 to operate at preset intervals, driving the cleaning element 2 to clean the observation window 100. For example, the electric drive 3 operates for one minute every ten minutes. If observation is required but there is an obstruction on the observation window 100, the manual switch can be manually activated to temporarily activate the electric drive 3. Under normal circumstances, the handle is not attached to the double-headed motor. When the electric drive 3 is inoperable, the handle is threadedly connected to the double-headed motor, and the cleaning element 2 can be driven to clean the observation window 100 by rotating the handle.

[0043] See Figure 1-3 , the present application also provides an observation window 100, on which the above-mentioned observation window cleaning device is provided, with all its beneficial effects.

[0044] The present application also provides a tobacco dryer, which is provided with the above-mentioned observation window 100, wherein the observation window is used to observe the drying condition of the tobacco, and the observation window cleaning device is used to clean the tobacco foam.
