Description

Technical Field

[0001] This utility model belongs to the field of food processing technology, and specifically relates to an exhaust pipe device for a base sauce wok. Background Technology

[0002] Hot pot broth is a product made by stir-frying various raw materials, including chili peppers, spices (star anise, Sichuan peppercorns, bay leaves), and seasonings (ginger slices, garlic cloves, scallions, etc.), in oil at high temperatures. This stir-frying process generates a large amount of oil fumes, necessitating the use of exhaust fans and air purifiers for extraction. Furthermore, to enhance the flavor, seasonings such as baijiu (Chinese liquor) are added during the stir-frying process; these flammable and volatile substances are sent to the exhaust fan via the exhaust pipe when the broth is being cooked in the wok. However, when these flammable and volatile substances reach a certain concentration, combined with the increased temperature after the exhaust fan has been running for a period of time, the combination of high temperature and flammable materials poses a risk of spontaneous combustion of the exhaust fan, thus creating a certain safety hazard. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing an exhaust pipe device for a base material frying pan, thereby reducing the concentration of flammable and volatile substances and minimizing safety hazards.

[0004] The technical solution for the purpose of this utility model is:

[0005] An exhaust pipe device for a base seasoning wok includes an exhaust pipe and an exhaust fan. The exhaust fan is installed on the exhaust pipe, and an air branch pipe is connected to the exhaust pipe. The air branch pipe has a ventilation hole, and a hinged damper that can be flipped open and closed is connected to the ventilation hole of the air branch pipe. The branch pipe is also provided with an adjustment device for adjusting the opening degree of the damper.

[0006] Furthermore, it also includes a one-way exhaust fan, which is installed in the ventilation hole.

[0007] Furthermore, the adjustment device can be an electric adjustment device or a manual adjustment device.

[0008] Furthermore, the damper includes an air plate, which is hinged to one side of the air branch pipe, and the adjustment device is located on the other side of the air branch pipe.

[0009] Furthermore, the damper includes two semi-circular air plates and a rotating shaft. The two semi-circular air plates are symmetrically fixed on the rotating shaft and hinged to the air branch pipe via the rotating shaft. The semi-circular air plates are located inside the air branch pipe and are clearance-fitted with the inner wall of the ventilation hole of the air branch pipe. The rotating shaft is located in the middle of the ventilation hole of the air branch pipe, and one end of the rotating shaft extends out of the air branch pipe. The adjusting device includes an adjusting mechanism and a positioning rod. The adjusting mechanism is located on the extension of the rotating shaft, and the positioning rod is fixed on the outside of the air branch pipe, located next to the extension end of the rotating shaft. The adjusting mechanism cooperates with the positioning rod to control the rotation angle of the rotating shaft.

[0010] Furthermore, the adjustment mechanism includes an adjustment plate, a locking nut, and an operating handle. The upper end of the positioning rod is provided with an external thread. The operating handle is connected to one side of the adjustment plate. The other side of the adjustment plate is provided with an arc-shaped adjustment groove. The arc-shaped adjustment groove is slidably engaged with the positioning rod. The locking nut is used to lock the adjustment plate.

[0011] Furthermore, the adjusting plate has a fan-shaped structure, and the arc-shaped adjusting groove is provided along the arc surface of the adjusting plate.

[0012] Furthermore, the air branch pipe is located at the inlet end of the exhaust duct.

[0013] The above technical solution has the following beneficial effects:

[0014] This invention features a simple structure. An air branch pipe is connected to the exhaust duct, and ventilation holes are provided on the air branch pipe. Air drawn in through these holes dilutes the concentration of flammable substances in the exhaust duct, thereby reducing the concentration of flammable and volatile substances, avoiding the risk of spontaneous combustion, and lowering safety hazards. A hinged, flip-openable damper is connected to the ventilation hole of the air branch pipe. The damper allows for free opening and closing of the ventilation hole. When stir-frying hot pot base, the damper is opened to allow air in; when not in use, the damper is closed to prevent dust from entering the exhaust duct. The air branch pipe also has an adjustment device for adjusting the damper opening. This device controls the amount of air entering through the ventilation hole, ensuring effective extraction of fumes and flammable substances from the exhaust duct connected to the exhaust fan, and preventing the ventilation hole from being too large and affecting the extraction effect of the wok.

[0015] The regulating device is electrically operated, facilitating automatic control and adjustment. Alternatively, a manual regulating device allows for easy adjustment of the vent opening and closing, saving costs.

[0016] The damper is hinged to the air branch pipe via a rotating shaft. The adjustment device includes an adjustment mechanism and a positioning rod. The adjustment mechanism cooperates with the positioning rod to control the rotation angle of the rotating shaft, thereby realizing the adjustment of the damper opening.

[0017] The adjustment mechanism includes an adjustment plate, a locking nut, and an operating handle. It has a simple structure, is easy to operate, and is inexpensive.

[0018] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details. Attached Figure Description
