该灭菌方法灭菌效果好，但是在进行灭菌操作时化学试剂或者化学气体容易对工作人员造成损害
[0018] This invention provides a sterilization device. A reaction chamber with a sealed cover is used. Seeds to be sterilized are placed inside the chamber. A second liquid reservoir is placed inside the chamber, containing a second reaction liquid. A control rod penetrates the side wall of the reaction chamber, with a first liquid reservoir on the rod containing the first reaction liquid. The control rod is rotatably and sealed to the side wall of the reaction chamber. Rotating the control rod adds the first reaction liquid to the second reaction liquid. The mixing of the first and second reaction liquids generates a sterilizing gas. This allows the reaction chamber to be sealed with a cover when sterilization of tobacco seeds is required. Then, the operator rotates a control lever outside the reaction chamber, which tilts the first liquid storage device located in the chamber's containment cavity. This causes the first reaction liquid in the first storage device to be poured into a second storage device also located in the containment cavity, where it mixes with the second reaction liquid to generate sterilizing gas. This sterilizing gas can then be used to sterilize the tobacco seeds placed in the containment cavity. During the sterilization of tobacco seeds using the aforementioned sterilization device, operators can use the rotation of a control lever to mix the first reaction liquid in the first storage container with the second reaction liquid in the second storage container outside the reaction chamber. This eliminates the need for direct contact with the first storage container to add the first reaction liquid to the second storage container, preventing splashing of the reaction liquid and thus improving safety during the sterilization process. Furthermore, because the operator operates outside the reaction chamber, and the chamber remains sealed during sterilization, the operator is protected from exposure to the sterilization environment. This also prevents the sterilization gases generated from the mixing of the first and second reaction liquids from harming the operator, further enhancing safety during the sterilization process.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of tobacco seed pretreatment technology, and in particular to a sterilization device. Background Technology
[0002] The quality of tobacco leaves directly determines the quality of the manufactured cigarettes, while the health of tobacco seeds determines the yield and quality of subsequent tobacco leaves. During harvesting, drying, storage, and transportation, tobacco seeds are highly susceptible to attaching to or carrying various pathogenic microorganisms, including fungi (such as anthracnose and damping-off fungi) and bacteria (such as bacterial wilt and angular leaf spot fungi). These pathogenic microorganisms invade the embryo during seed germination, ultimately leading to reduced tobacco leaf yield and quality deterioration (such as leaf lesions and reduced aroma content). Therefore, pretreatment of tobacco seeds (i.e., sterilization) is a crucial preliminary step in ensuring the quality of tobacco seedlings and stabilizing tobacco leaf production.
[0003] In existing technologies, the most widely used method for sterilizing tobacco seeds is chemical sterilization, such as sterilizing the seeds with chemical reagents or gases. This sterilization method is effective, but the chemical reagents or gases used during the sterilization process can easily cause harm to workers.
[0004] Therefore, a sterilization device is urgently needed to solve the above-mentioned technical problems. Utility Model Content

The control rod extends along a first direction and passes through the side wall of the reaction chamber; the control rod is at least partially located inside the receiving cavity; the control rod is rotatably connected to the side wall of the reaction chamber and is sealed to the side wall of the reaction chamber; the first direction is horizontal. The first liquid storage container is installed on the control rod and located inside the receiving cavity. The second liquid storage container is located inside the receiving cavity; the first liquid storage container contains a first reaction liquid, and the second liquid storage container contains a second reaction liquid. Rotating the control rod allows the first and second reaction liquids to mix, generating a sterilizing gas.
[0008] In some embodiments, a connecting through hole is provided on the side wall of the reaction chamber along the first direction; the control rod passes through the connecting through hole and is rotatably connected to the connecting through hole; a sealing element is provided between the hole wall of the connecting through hole and the outer side wall of the control rod.
[0009] In some embodiments, a sealing groove is provided on one end face of the opening of the reaction chamber and on the side of the cover facing the reaction chamber, and a sealing protrusion is provided on the other; the sealing protrusion is adapted to the sealing groove.
[0010] In some embodiments, a flexible sealing ring is provided between the groove wall of the sealing groove and the outer side wall of the sealing protrusion; the cross-sectional shape of the flexible sealing ring is "U".
[0011] In some embodiments, a locking assembly is provided on the side wall of the reaction chamber; the locking assembly is capable of restricting the control lever from rotating about its own axis.
[0012] In some embodiments, the locking assembly includes a locking block and a locking rod; the locking block is fixedly disposed on the side wall of the reaction chamber; a first locking through hole is formed on the locking block; a second locking through hole is formed on the control rod; the opening directions of the first locking through hole and the second locking through hole are the same, and both are set at an angle to the axis of the control rod; the locking rod can pass through both the first locking through hole and the second locking through hole simultaneously to restrict the control rod from rotating around its own axis.
[0013] In some embodiments, the bottom inner wall of the reaction chamber includes a reaction area and a seed placement area arranged along a second direction; the second liquid storage device is disposed in the reaction area; the tobacco seeds are placed in the seed placement area; in a third direction, the orthographic projection of the first liquid storage device is located within the reaction area and at least partially within the outer contour of the orthographic projection of the second liquid storage device; the third direction, the second direction, and the first direction are arranged at angles to each other.
[0014] In some embodiments, the bottom inner wall of the reaction chamber further includes an isolation region; the isolation region is disposed between the reaction region and the seed placement region, and is capable of separating the reaction region and the seed placement region in the second direction.
[0015] In some embodiments, the end of the control lever is provided with an operating handle; the operating handle is located outside the reaction chamber.
[0016] In some embodiments, the cover is provided with an exhaust assembly; the exhaust assembly is capable of selectively connecting the receiving cavity to an exhaust gas collection assembly.
[0017] The beneficial effects of this utility model are:
[0018] This invention provides a sterilization device. A reaction chamber with a sealed cover is used. Seeds to be sterilized are placed inside the chamber. A second liquid reservoir is placed inside the chamber, containing a second reaction liquid. A control rod penetrates the side wall of the reaction chamber, with a first liquid reservoir on the rod containing the first reaction liquid. The control rod is rotatably and sealed to the side wall of the reaction chamber. Rotating the control rod adds the first reaction liquid to the second reaction liquid. The mixing of the first and second reaction liquids generates a sterilizing gas. This allows the reaction chamber to be sealed with a cover when sterilization of tobacco seeds is required. Then, the operator rotates a control lever outside the reaction chamber, which tilts the first liquid storage device located in the chamber's containment cavity. This causes the first reaction liquid in the first storage device to be poured into a second storage device also located in the containment cavity, where it mixes with the second reaction liquid to generate sterilizing gas. This sterilizing gas can then be used to sterilize the tobacco seeds placed in the containment cavity. During the sterilization of tobacco seeds using the aforementioned sterilization device, operators can use the rotation of a control lever to mix the first reaction liquid in the first storage container with the second reaction liquid in the second storage container outside the reaction chamber. This eliminates the need for direct contact with the first storage container to add the first reaction liquid to the second storage container, preventing splashing of the reaction liquid and thus improving safety during the sterilization process. Furthermore, because the operator operates outside the reaction chamber, and the chamber remains sealed during sterilization, the operator is protected from exposure to the sterilization environment. This also prevents the sterilization gases generated from the mixing of the first and second reaction liquids from harming the operator, further enhancing safety during the sterilization process.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.
[0025] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0026] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0027] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0028] Combination Figure 1 , Figure 2 As shown, this embodiment provides a sterilization device for sterilizing tobacco seeds. The sterilization device includes: a reaction chamber 1, a cover 2, a control lever 3, a first liquid storage container 4, and a second liquid storage container 5.
[0029] like Figure 1As shown, the reaction chamber 1 has a cubic or cylindrical structure. An internal cavity is provided inside the reaction chamber 1, and the reaction chamber 1 also has an opening. The tobacco seeds can be placed inside the cavity.
[0030] The aforementioned cover 2 is positioned at the opening of the reaction chamber 1 and is capable of sealingly connecting with the opening of the reaction chamber 1. It is readily understood that the cover 2 should be adapted to fit the opening of the reaction chamber 1; that is, when the reaction chamber 1 has a cubic box structure (e.g., a cube-shaped box structure), the opening of the reaction chamber 1 is square, and the shape of the cover 2 is also square; when the reaction chamber 1 has a cylindrical box structure, the opening of the reaction chamber 1 is circular, and the shape of the cover 2 is also circular. Furthermore, the size of the cover 2 should be slightly larger than the opening of the reaction chamber 1 to completely cover the opening of the reaction chamber 1.
[0031] Combination Figure 1 , Figure 2 As shown, the control rod 3 extends along a first direction X1 and passes through the side wall of the reaction chamber 1. The first direction X1 is horizontal. The control rod 3 is at least partially located inside the receiving cavity. It is easy to understand that the control rod 3 can pass through only one side wall of the reaction chamber 1, i.e., one end of the control rod 3 is located inside the reaction chamber 1, and the other end is located outside the reaction chamber 1; or the control rod 3 can pass through both side walls of the reaction chamber 1 simultaneously, i.e., the middle position of the control rod 3 is located inside the reaction chamber 1, and both ends of the control rod 3 are located outside the reaction chamber 1. Those skilled in the art can configure it according to the specific shape, size, and usage requirements of the reaction chamber 1, which will not be described in detail here. The control rod 3 is rotatably connected to the side wall of the reaction chamber 1 and is sealed to the side wall of the reaction chamber 1.
[0032] like Figure 2 As shown, the first liquid storage component 4 is installed on the control rod 3, and the first liquid storage component 4 is located inside the receiving cavity. The first liquid storage component 4 is, for example, a liquid storage box or a liquid storage tank. Here, the first liquid storage component 4 is installed on the control rod 3 in the following ways: multiple mounting grooves are provided on the rod body of the control rod 3, and the first liquid storage component 4 is snapped into the mounting grooves on the control rod 3; or, the bottom of the first liquid storage component 4 is directly welded to the rod body of the control rod 3; or, the control rod 3 includes multiple sub-rods, and the first liquid storage component 4 is welded between two adjacent sub-rods. Those skilled in the art can configure it according to actual usage requirements, and will not be listed exhaustively here. The second liquid storage component 5 is also disposed inside the receiving cavity, and the second liquid storage component 5 is, for example, a liquid storage box or a liquid storage tank.
[0033] The first liquid reservoir 4 contains a first reaction solution, and the second liquid reservoir 5 contains a second reaction solution. For example, the first reaction solution is a hydrochloric acid solution, and the second reaction solution is a sodium hypochlorite solution; or, the first reaction solution is a sodium chlorite solution, and the second reaction solution is a hydrochloric acid solution. Rotating the control lever 3 mixes the first and second reaction solutions to generate a sterilizing gas. For example, when the first reaction solution is a hydrochloric acid solution and the second reaction solution is a sodium hypochlorite solution, the mixture generates chlorine gas, which then performs a sterilization function; when the first reaction solution is a sodium chlorite solution and the second reaction solution is a hydrochloric acid solution, the mixture generates chlorine dioxide, which also performs a sterilization function.
[0034] It is not difficult to understand that, in order to achieve the mixing of the first and second reaction liquids after rotating the control lever 3, the positional relationship between the first and second liquid storage components 4 and 5 can take various forms. Taking the second liquid storage component 5 as a storage box with a fixed shape and size as an example, the easiest to understand is: the first liquid storage component 4 is a smaller storage box, and in the vertical direction, the first liquid storage component 4 and the second liquid storage component 5 are positioned directly opposite each other. In this way, when the first liquid storage component 4 is tilted, the first reaction liquid inside can spill into the second liquid storage component 5 and mix with the second reaction liquid; or, the first liquid storage component 4 is a storage box, but in order to store more first reaction liquid, the horizontal dimension of the first liquid storage component 4 is set to be larger. In this case, part or one end of the first liquid storage component 4 can be positioned vertically corresponding to the second liquid storage component 5. When the first liquid storage component 4 is tilted toward the direction of the second liquid storage component 5, the first reaction liquid inside can also be spilled into the second liquid storage component 5 and mixed with the second reaction liquid; or, the first liquid storage component 4 is a liquid storage box, but in order to store more first reaction liquid, the vertical dimension of the first liquid storage component 4 is set to be larger (i.e., the first liquid storage component 4 is a long strip-shaped liquid storage box extending in the vertical direction). In this case, the first liquid storage component 4 can be offset from the second liquid storage component 5 in the vertical direction (the greater the height of the first liquid storage component 4, the greater the offset distance should be to avoid the first reaction liquid spilling onto the outside of the second liquid storage component 5 after the first liquid storage component 4 is tilted). In this way, when the first liquid storage component 4 is tilted toward the direction of the second liquid storage component 5, the first reaction liquid inside can also be spilled into the second liquid storage component 5 and mixed with the second reaction liquid.
[0035] If the size of the second liquid storage component 5 is set to be much larger than the size of the first liquid storage component 4, then regardless of whether the first liquid storage component 4 is a smaller liquid storage box, a liquid storage box with an increased size in the horizontal direction, or a liquid storage box with an increased size in the vertical direction, by setting the first liquid storage component 4 to correspond with the second liquid storage component 5 in the vertical direction, the first reaction liquid inside the first liquid storage component 4 can be spilled into the second liquid storage component 5 and mixed with the second reaction liquid after the first liquid storage component 4 is tilted.
[0036] As can be clearly seen from the above description, the positional relationship between the first liquid storage component 4 and the second liquid storage component 5 needs to be specifically set according to the shape and size of the first liquid storage component 4 and the shape and size of the second liquid storage component 5. Therefore, the positional relationship between the first liquid storage component 4 and the second liquid storage component 5 will not be specifically limited here, as long as the purpose of "the first reaction liquid and the second reaction liquid can be mixed after rotating the control lever 3" can be achieved.
[0037] Therefore, the sterilization device provided by this utility model includes a reaction chamber 1 with a sealing cover 2. Seeds to be sterilized are placed in the receiving cavity of the reaction chamber 1. A second liquid storage device 5 is provided in the receiving cavity of the reaction chamber 1, and a second reaction liquid is placed in the second liquid storage device 5. In addition, a control rod 3 is provided that penetrates the side wall of the reaction chamber 1, and a first liquid storage device 4 is provided on the control rod 3. The first reaction liquid is placed in the liquid storage device. The control rod 3 is rotatably and sealed to the side wall of the reaction chamber 1. Rotating the control rod 3 can add the first reaction liquid to the second reaction liquid. The first reaction liquid and the second reaction liquid mix to generate sterilization gas. This allows the following steps to be taken when sterilizing tobacco seeds: First, the reaction chamber 1 is sealed with the cover 2. Then, the operator rotates the control lever 3 outside the reaction chamber 1, which tilts the first liquid storage device 4 located in the containment cavity of the reaction chamber 1 on the control lever 3. This causes the first reaction liquid in the first liquid storage device 4 to be poured from the first liquid storage device 4 into the second liquid storage device 5, which is also located in the containment cavity. The reaction liquid mixes with the second reaction liquid in the second liquid storage device 5 and generates sterilizing gas. The sterilizing gas can then be used to sterilize the tobacco seeds placed in the containment cavity. During the sterilization of tobacco seeds using the aforementioned sterilization device, the operator can use the rotation of the control lever 3 to mix the first reaction liquid in the first storage container 4 with the second reaction liquid in the second storage container 5 outside the reaction chamber 1. This eliminates the need for direct contact with the first storage container 4 to add the first reaction liquid to the second storage container 5, preventing splashing of the reaction liquid and thus improving safety during the sterilization process. Furthermore, because the operator operates outside the reaction chamber 1, and the reaction chamber 1 is sealed during sterilization, the operator is prevented from being exposed to the sterilization environment. This also prevents the sterilization gas generated by the mixing of the first and second reaction liquids from harming the operator, further enhancing safety during the sterilization process.
[0038] In some embodiments, a connecting through hole is provided on the side wall of the reaction chamber 1 along the first direction X1. The control rod 3 passes through the connecting through hole and is rotatably connected to it. A sealing element is provided between the wall of the connecting through hole and the outer wall of the control rod 3. This sealing element can be, for example, a lip seal (i.e., an oil seal), a mechanical seal, or a sealing packing. Lip seals and mechanical seals are common rotating shaft sealing elements; their specific structures can be found in relevant technologies and will not be described in detail here. Sealing packing is also a common rotating shaft sealing method. In use, a packing cavity can be opened on the outer wall of the control rod 3 or the wall of the connecting through hole, and the sealing packing can be filled into the packing cavity. The sealing packing can make close contact with the wall of the connecting through hole or the outer wall of the control rod 3. Simultaneously, the lubricant impregnated in the sealing packing will be squeezed out to form an oil film, which can both lubricate and seal. Through the above arrangement, both rotatable connection and sealing connection between the control rod 3 and the side wall of the reaction chamber 1 can be achieved simultaneously. The structure is simple and easy to manufacture.
[0039] In some embodiments, a sealing groove is formed on one end face of the opening of the reaction chamber 1 and on the side of the cover 2 facing the reaction chamber 1, while a sealing protrusion is formed on the other. The sealing protrusion here is adapted to the sealing groove. Taking the example of a sealing groove at the end face of the opening of the reaction chamber 1 and a sealing protrusion on the side of the cover 2 facing the reaction chamber 1, the term "adapted" means that the shape and size of the sealing groove are the same as the shape and size of the sealing protrusion. For example, when the reaction chamber 1 has a cylindrical box structure, the sealing groove has a circular annular structure, and the sealing protrusion also has a circular annular structure. The inner and outer diameters of the sealing protrusion are the same as (or slightly smaller than) the inner and outer diameters of the sealing groove. When the reaction chamber 1 has a cubic box structure (e.g., a cube-shaped box structure), the sealing groove has a square annular structure, and the sealing protrusion also has a square annular structure. The width of the sealing protrusion (i.e., the dimension between the inner and outer walls of the square annular protrusion) is the same as (or slightly smaller than) the width of the sealing groove. When the reaction chamber 1 has other box structures, the arrangement of the sealing groove and sealing protrusion is the same, and will not be listed exhaustively here. By adopting the above configuration, the contact area between the end face of the cover 2 and the opening of the reaction chamber 1 can be increased, thereby extending the leakage path and increasing the resistance to gas flow. At the same time, multiple sealing barriers are formed between the outer wall of the sealing protrusion and the inner wall of the sealing groove (that is, the "face contact" between the top of the protrusion and the bottom of the groove can form a sealing barrier, and the "side contact" between the side of the protrusion and the inner wall of the groove can also form a sealing barrier), which greatly improves the sealing performance of the reaction chamber 1, prevents the sterilization gas inside the containment cavity from escaping to the external environment, and thus ensures the safety of the process of sterilizing tobacco seeds.
[0040] In some embodiments, a flexible sealing ring is provided between the groove wall of the sealing groove and the outer wall of the sealing protrusion. The cross-sectional shape of the flexible sealing ring is U-shaped. It is easy to understand that the cross-sectional direction here is perpendicular to the plane where the flexible sealing ring is located. For example, if the flexible sealing ring is horizontally arranged, then the cross-sectional direction here is vertical. The flexible sealing ring is, for example, a rubber sealing ring. With this arrangement, the flexible sealing ring can fill the tiny gap between the inner wall of the sealing groove and the outer wall of the sealing protrusion, further improving the sealing performance of the reaction chamber 1.
[0041] like Figure 1 , Figure 2 As shown, in some embodiments, a locking component 6 is provided on the side wall of the reaction chamber 1. This locking component 6 restricts the control lever 3 from rotating around its own axis. By restricting the control lever 3 from rotating around its own axis using the locking component 6, it is possible to prevent the first liquid storage box from tilting due to vibration or misoperation during the sterilization preparation process (i.e., before the tobacco seeds are placed into the receiving cavity of the reaction chamber 1 or before the cover 2 covers the opening of the reaction chamber 1), causing the first reaction liquid to be added prematurely to the second reaction liquid, resulting in premature generation of sterilization gas. By providing the locking component 6, the rotation of the control lever 3 can be controlled, improving the reliability of the sterilization device during use.
[0042] For example, the locking component 6 includes a locking block and a locking rod. The locking block is fixedly mounted on the side wall of the reaction chamber 1. It is easily understood that the locking block and the connecting through hole are located on the same side wall of the reaction chamber 1. In other words, the locking block is located on the side wall of the reaction chamber 1 through which the control rod 3 passes. The locking block has a first locking through hole, and the control rod 3 has a second locking through hole. The opening directions of the first and second locking through holes are the same, and both opening directions are set at an angle to the axis of the control rod 3, for example, 90°. The locking rod can pass through both the first and second locking through holes simultaneously to restrict the control rod 3 from rotating around its own axis. This configuration effectively restricts the rotation of the control rod 3 around its own axis, resulting in a simple structure and convenient use. Furthermore, it is easy to understand that the aforementioned locking rod should simultaneously match the first locking through hole and the second locking through hole. That is, the shape and size of the cross-sectional shape of the aforementioned locking rod are the same as the shape and size of the cross-sectional shape of the first locking through hole, and also the same as the shape and size of the cross-sectional shape of the second locking through hole. Here, the cross-sectional direction is perpendicular to the extension direction of the aforementioned locking rod. Of course, the aforementioned locking component 6 can also be configured with other structures. For example, the aforementioned locking component is a clamp, which clamps the control rod 3 through two arc-shaped clamping blocks. The friction between the arc-shaped clamping blocks and the outer wall of the control rod 3 restricts the rotation of the control rod 3 around its own axis. Those skilled in the art can make specific settings according to actual usage requirements, which will not be described in detail here.
[0043] Combination Figure 1 , Figure 2 As shown, in some embodiments, the bottom inner wall of the reaction chamber 1 includes a reaction area S1 and a seed placement area S2 arranged along the second direction X2. The second liquid storage device 5 is disposed in the reaction area S1, and the tobacco seeds are placed in the seed placement area S2. In the third direction X3, the orthographic projection of the first liquid storage device 4 is located within the reaction area S1, and at least partially within the outer contour of the orthographic projection of the second liquid storage device 5. Here, the third direction X3, the second direction X2, and the first direction X1 are arranged at an angle to each other. This angle is, for example, 90°. With the above arrangement, it is convenient to add the first reaction liquid in the first liquid storage device 4 to the second liquid storage device 5, while avoiding spillage of the reaction liquid onto the tobacco seeds during the addition process, thus preventing the tobacco seeds from being contaminated by the reaction liquid and improving the practicality of the sterilization device. Preferably, on the third direction X3, the orthographic projection of the first liquid storage component 4 is completely within the outer contour of the orthographic projection of the second liquid storage component 5, which further facilitates the addition of the first reaction liquid in the first liquid storage component 4 to the second liquid storage component 5.
[0044] like Figure 2As shown, in some embodiments, the bottom inner wall of the reaction chamber 1 further includes an isolation region S3. This isolation region S3 is disposed between the reaction region S1 and the seed placement region S2, and can separate the reaction region S1 and the seed placement region S2 in the second direction X2. This arrangement further prevents the reaction solution from spilling onto the tobacco seeds during the addition of the reaction solution, thus preventing the tobacco seeds from being contaminated by the reaction solution.
[0045] like Figure 1 , Figure 2 As shown, in some embodiments, an operating handle 31 is provided at the end of the control lever 3, and the operating handle 31 is located outside the reaction chamber 1. That is, an operating handle 31 is provided at one end of the control lever 3 outside the reaction chamber 1 (or at both ends outside the reaction chamber 1). With this arrangement, it is convenient for the operator to rotate the control lever 3 to add reaction solution, thus improving the practicality of the sterilization device.
[0046] In some embodiments, the cover 2 is provided with an exhaust assembly (not shown in the figure). This exhaust assembly can selectively connect the receiving cavity to a waste gas collection assembly. Exemplarily, the exhaust assembly includes an exhaust pipe and a control valve disposed on the exhaust pipe. The waste gas collection assembly is, for example, a waste gas collection bucket or a waste gas collection pipe. One end of the exhaust pipe communicates with the interior of the receiving cavity, and the other end communicates with the waste gas collection assembly. By changing the opening and closing state of the control valve, the connection and disconnection between the receiving cavity and the waste gas collection assembly can be achieved. With this configuration, the sterilizing gas inside the receiving cavity can be discharged after sterilization, preventing residual sterilizing gas in the receiving cavity from harming workers during the removal of sterilized tobacco seeds, further improving the practicality of the sterilization device.
[0047] 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 will be able to make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments 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.
