[0001] This utility model relates to the field of smokehouse technology, specifically to a sealing door assembly for smokehouses. Background Technology

[0002] A smokehouse is a piece of equipment used for food processing. By controlling temperature, humidity and smoke concentration, it imparts unique flavor, color and preservative effects to food. Its working principle combines heat processing, smoke penetration and environmental control technologies. By precisely controlling physical and chemical conditions, smokehouses standardize and industrialize traditional smoking processes, improving efficiency while ensuring food safety and flavor consistency. Smoking ovens are usually equipped with a sealing door assembly at the opening.

[0003] The existing sealing door assembly mainly consists of a sealing door, a rotating shaft, and a sealing ring. Rotating the sealing door causes the sealing ring at the contact point between the furnace body and the sealing door to deform, ensuring the sealing of the furnace body during use. However, since the sealing door is fixed by two sets of latches on the surface of the furnace body, the contact area between the latches and the sealing door is small, and the pressure on the sealing door is low in some areas. As a result, the sealing ring at these locations does not deform sufficiently, leading to gaps at the contact point between the sealing door and the furnace body, which in turn affects the fumigation operation inside the furnace body.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.

[0032] Example 1

[0033] Please see Figure 1-5 This embodiment provides a technical solution: a sealing door assembly for a smoking oven, including an oven body 1 and a protective part 2. The oven body 1 mainly houses a heating system, a smoke generation system, an air circulation system, a sealing and pressure control system, and an automatic control system. The heating system is activated to raise the oven temperature to a set value. Then, a fan is used to evenly diffuse the smoke into the oven, ensuring that the food surface is fully in contact with the smoke particles. During the process, the oven environment is regulated by a heater and a humidification / dehumidification system to balance the food dehydration and smoke adsorption processes. Finally, after smoking, the exhaust system is activated to remove residual smoke, and the food temperature is reduced through natural or forced cooling to prevent excessive shrinkage. This is existing publicly available technology. The protective part 2 is located at the central opening of the oven body 1. The protective part 2 has a protective frame 201 connected to the opening of the oven body 1. Rotating shafts are fixedly connected to the upper and lower sides of the protective frame 201, and the protective frame 201 is rotatably connected to the inside of the opening of the oven body 1 via the rotating shafts. A sliding plate 202, made of stainless steel, is slidably connected inside the protective frame 201. To prevent the sliding plate 202 from rusting during prolonged use, the sliding plate 202 is located inside the protective frame 201 and connected to a transmission plate 203 on one side. The sliding plate 202 is welded to the transmission plate 203. When the sliding plate 202 moves, it can drive the transmission plate 203 to move in the same way. The transmission plate 203 is hinged to the upper and lower sides with a first connecting plate 204. When the transmission plate 203 moves, it can drive the first connecting plate 204 to rotate. A first sealing plate 20 is hinged to the other side of the first connecting plate 204. 5. The rotation of the first connecting plate 204 can drive the first sealing plate 205 to move vertically. The transmission plate 203 is hinged to the left and right sides with the second connecting plate 206. The movement of the transmission plate 203 can drive the second connecting plate 206 to rotate. The other side of the second connecting plate 206 is hinged with the second sealing plate 207. The rotation of the second connecting plate 206 can drive the second sealing plate 207 to move laterally. The movement of the transmission plate 203 drives the first sealing plate 205 and the second sealing plate 207 to move inside the protective frame 201.

[0034] Example 2

[0035] Please see Figure 1-5 The protective part 2 also has a spring 208 connected to the inner wall of the protective frame 201, such as... Figure 5The diagram shows the compressed deformation state. Spring 208 is connected to the inner wall of protective frame 201 via a snap fastener, and the other end of spring 208 is connected to transmission plate 203. Spring 208 is connected to transmission plate 203 via a snap fastener. During the movement of transmission plate 203, transmission plate 203 will deform. A sealing gasket is provided on the other side of the connection between first sealing plate 205 and first connecting plate 204, and a sealing gasket is provided on the other side of the connection between second sealing plate 207 and second connecting plate 206. During the movement of first sealing plate 205 and second connecting plate 206, the sealing gaskets will be squeezed, thereby improving the sealing performance of protective frame 201 after it is closed. First sealing plate 205 is slidably connected to protective frame 201, and second sealing plate 207 is slidably connected to protective frame 201. The protective frame 201 can limit the first sealing plate 205 and second sealing plate 207, improving the stability of first sealing plate 205 and second sealing plate 207 during the unfolding process.

[0036] A limiting plate 210 is fixedly connected to the inner wall of the protective frame 201, and two sets of limiting plates 210 are provided. Both sets of limiting plates 210 are in contact with the first sealing plate 205. The two sets of limiting plates 210 can limit the movement of the first sealing plate 205, improving its stability during movement. The limiting plates 210 are made of stainless steel. The two sets of limiting plates 210 are also in contact with the second sealing plate 207, limiting the movement of the second sealing plate 207 and improving its stability during movement. To ensure the stability of the sealing plate 207 during movement, a sliding rod 209 is fixedly connected inside the protective frame 201, and the sliding rod 209 is slidably connected to the transmission plate 203. The sliding rod 209 can limit the transmission plate 203, reducing the possibility of displacement during the movement of the transmission plate 203. The sliding rod 209 is a cylinder, and it passes through the hole formed in the center of the spring 208. The sliding rod 209 can limit the spring 208, reducing the possibility of deformation and misalignment of the spring 208.

[0037] Working principle: First, when it is necessary to open the protective frame 201, manually open the latch on the surface of the furnace body 1. During the process of the latch separating from the sliding plate 202, the spring 208 will restore its deformation and push the transmission plate 203 to move outward of the protective frame 201. Since the transmission plate 203 is hinged to the first connecting plate 204, and the first connecting plate 204 is hinged to the first sealing plate 205, the movement of the transmission plate 203 will drive the first sealing plate 205 to move under the action of the first connecting plate 204 and gradually be stored inside the protective frame 201. Since the transmission plate 203 is hinged to the second connecting plate 206, and the second connecting plate 206 is hinged to the second sealing plate 207, the movement of the transmission plate 203 will also drive the second sealing plate 207 to move under the action of the second connecting plate 206 and be stored inside the protective frame 201. Then, pull the handle on the outside of the protective frame 201 to fully open the protective frame 201.

[0038] Secondly, when it is necessary to close the protective frame 201, manually rotate the protective frame 201 to enter the opening of the furnace body 1, and then close the latch on the outer wall of the furnace body 1. During the closing process, the latch will press the sliding plate 202. The movement of the sliding plate 202 will drive the transmission plate 203 to move. The movement of the transmission plate 203 will drive the first sealing plate 205 and the second sealing plate 207 to move. The first sealing plate 205 and the second sealing plate 207 will move and embed into the groove on the inner side of the furnace body 1, causing the sealing gasket to deform, thereby improving the sealing performance of the protective frame 201 after it is closed. During the movement of the transmission plate 203, the spring 208 will be squeezed and deformed, which will facilitate the subsequent opening and use of the protective frame 201.
