Description

Technical Field

[0001] The utility model relates to the technical field of tobacco flue-curing room equipment, in particular to an air window structure of a tobacco flue-curing room. Background Art

[0002] Tobacco curing rooms are usually equipped with air intake windows, dehumidification windows, ventilation windows, and fire control windows to adjust the temperature and humidity of the tobacco curing room. The dehumidification windows are generally shutters with fans, while the air intake windows are generally electric windows. The structure of the air intake window can be referred to CN201262006Y. It consists of a window frame, blades, and a low-speed motor. The middle position of the upper and lower sides of the blades is connected to a connecting shaft. The blades are rotatably mounted on the window frame via the connecting shaft. The motor is installed at the top of the window frame to drive the blades to rotate, thereby opening and closing the air window. The air window of the above structure is very widely used, but it has a disadvantage. When the air window is opened, it does not have a protective device to block rats, which may cause rats to crawl into the tobacco curing room. Therefore, the air window needs to be improved. Utility Model Content

[0003] In order to solve the problems mentioned in the background technology, the purpose of the present utility model is to provide an air window structure for a tobacco flue-curing room.

[0004] In order to achieve the above objectives, the technical solution of the utility model is:

[0005] A louver structure for a tobacco flue-curing room comprises a window frame, blades, a frame and a motor, the window frame being rectangular, the shape of the blades corresponding to the inner contour of the window frame, an upper rotating shaft and a lower rotating shaft being respectively connected to the middle of the upper and lower sides of the blades, the upper rotating shaft and the lower rotating shaft being respectively rotatably mounted at the middle positions of the upper and lower sides of the window frame, the frame being mounted on the top edge of the window frame, the motor being mounted on the frame and being transmission-connected to the upper rotating shaft, a rat guard being respectively connected to the middle of the front and rear sides of the blades, the rat guard being longitudinally arranged and perpendicular to the blades, the length of the rat guard corresponding to the length of the blades, the width of the rat guard being half the width of the blades, and a plurality of air holes being provided on the rat guard.

[0006] Furthermore, resistance strips are fixed to the opposite surfaces of the left and right sides of the window frame. The resistance strips are parallel to the long sides of the blades. The two ends of the resistance strips in the length direction are respectively connected to the upper and lower sides of the window frame. The two resistance strips are arranged in a centrally symmetrical manner around the axis of the motor.

[0007] The beneficial effect of the utility model is that when the blades are rotated to open the air window, the two mouse guards are just located inside the window frame. The mouse guards have air holes, which will not affect the ventilation and can effectively prevent mice from passing through the window frame, thereby achieving the function of mouse prevention.

[0012] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only 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 are within the scope of protection of the present invention.

[0013] like Figure 1-Figure 3 As shown, a louver structure of a tobacco flue-curing room includes a window frame 1, blades 2, a frame 3 and a motor 4. The window frame 1 is rectangular, and the shape of the blade 2 corresponds to the inner contour of the window frame 1. The middle parts of the upper and lower sides of the blade 2 are respectively connected with an upper rotating shaft 21 and a lower rotating shaft 22. The upper rotating shaft 21 and the lower rotating shaft 22 are respectively rotatably mounted at the middle positions of the upper and lower sides of the window frame 1. The frame 3 is mounted on the top edge of the window frame 1. The motor 4 is mounted on the frame 3 and the main shaft of the motor 4 is connected to the upper rotating shaft 21 through a coupling 5. The middle parts of the front and rear sides of the blade 2 are respectively connected with a mouse guard 23. The mouse guard 23 is longitudinally arranged and perpendicular to the blade 2. The length of the mouse guard 23 corresponds to the length of the blade 2, and the width of the mouse guard 23 is half the width of the blade 2. The mouse guard 23 is provided with a plurality of air holes 231.

[0014] In actual use, the motor 4 is used to drive the blade 2 to rotate, thereby opening the air louver. The rotation angle of the blade 2 can be set so that when the air louver is opened, the two mouse guards 23 are just located in the window frame 1, thereby achieving the effect of blocking mice.

[0015] In this embodiment, interference strips 11 are fixed to the opposite surfaces of the left and right sides of the window frame 1. The interference strips 11 are parallel to the long sides of the blades 2. The two ends of the interference strips 11 in the length direction are respectively connected to the upper and lower sides of the window frame 1. The two interference strips 11 are arranged symmetrically around the axis of the motor 4. The interference strips 11 can block the blades 2 or the mouse guard plate 23, so that the blades 2 or the guard plate are more tightly connected to the window frame 1, further improving the mouse-blocking effect.

[0016] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. All modifications, equivalent replacements, improvements, etc. within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
