[0031] Figure 1 This is a structural diagram of the exhaust device 1 of the utility model. Figure 2It is a structural diagram of the adjustment sleeve 12 in another perspective, combined with Figure 1 and Figure 2 The exhaust device 1 of this embodiment includes an exhaust pipe 11, an adjusting sleeve 12, a cover plate 13 and a locking structure 14. The exhaust pipe 11 is passed through in an up-down manner, and the adjusting sleeve 12 is passed through in an up-down manner, and the adjusting sleeve 12 and the exhaust pipe 11 are in an inner-outer-outer position, and the side wall of the adjusting sleeve 12 is provided with an exhaust port 121. The cover plate 13 is provided on the top of the adjusting sleeve 12, and can cover the upper end opening of the adjusting sleeve 12. The locking structure 14 is configured to lock the adjusting sleeve 12 and the exhaust pipe 11. Among them, the adjusting sleeve 12 can move up and down relative to the exhaust pipe 11, so that the exhaust port 121 is raised above the exhaust pipe 11, or the exhaust pipe 11 covers the exhaust port 121.

[0032] Specifically, the exhaust gas can be discharged upward through the through exhaust pipe 11. The cover plate 13 and the adjustment sleeve 12 form a cover structure with the opening facing downward. The cover plate 13 can prevent rainwater or foreign objects from falling into the exhaust pipe 11. The adjustment sleeve 12 can move up and down relative to the exhaust pipe 11. When exhaust is needed, the adjustment sleeve 12 is driven to move upward and extended so that the exhaust port 121 on the side wall of the adjustment sleeve 12 is higher than the exhaust pipe 11. The locking structure 14 is used to lock the adjustment sleeve 12 on the exhaust pipe 11, so that the exhaust gas can pass through the exhaust pipe 11 upward and be discharged from the exhaust port 121. When exhaust is not needed, the locking structure 14 is released to lock the adjusting sleeve 12, and the adjusting sleeve 12 is driven to move downward until the side wall of the exhaust pipe 11 can cover the exhaust port 121. The cover structure formed by the cover plate 13 and the adjusting sleeve 12 is arranged on the upper end opening of the exhaust pipe 11 to cover the exhaust pipe 11 and prevent foreign matter from entering the exhaust pipe 11. At the same time, when the exhaust is closed, the position of the cover plate 13 and the adjusting sleeve 12 can be lowered to reduce the phenomenon that the size of the exhaust equipment 1 protrudes and affects transportation.

[0033] In practice, both the exhaust pipe 11 and the adjustment sleeve 12 extend axially in the vertical direction. The exhaust pipe 11 can be sheathed around the outer periphery of the adjustment sleeve 12, ensuring that the adjustment sleeve 12 and the exhaust pipe 11 overlap and improving the installation stability of the adjustment sleeve 12. Alternatively, the adjustment sleeve 12 can be sheathed around the outer periphery of the exhaust pipe 11.

[0034] Figure 3 This is a structural diagram of the exhaust pipe 11 of the present invention, refer to Figure 3 The exhaust pipe 11 is a cylindrical structure with two open ends and a hollow interior. Specifically, the cross section of the exhaust pipe 11 is circular, that is, the exhaust pipe 11 is cylindrical. In other embodiments, the cross section of the exhaust pipe 11 can also be rectangular, polygonal, elliptical or other shapes.

[0035] Continue to refer to 1 and Figure 2In this embodiment, the exhaust pipe 11 is sleeved on the outer periphery of the adjustment sleeve 12. The shape of the adjustment sleeve 12 is adapted to the exhaust pipe 11, that is, it is also cylindrical.

[0036] Furthermore, there is a gap between the inner wall of the exhaust pipe 11 and the outer wall of the adjustment sleeve 12 , which facilitates the adjustment sleeve 12 to move up and down relative to the exhaust pipe 11 while ensuring the stability of the adjustment sleeve 12 .

[0037] The sidewall of the adjustment sleeve 12 is provided with an exhaust port 121. The number of exhaust ports 121 can be one, two, three, or another number, depending on actual needs. If there are multiple exhaust ports 121, the multiple exhaust ports 121 are spaced apart along the circumference of the adjustment sleeve 12.

[0038] Specifically, the adjusting sleeve 12 includes an upper sleeve 122, a lower sleeve 123 and a plurality of connecting rods 124. The upper sleeve 122 and the lower sleeve 123 both extend axially in the upper and lower directions. The upper sleeve 122 and the lower sleeve 123 are spaced apart in the upper and lower directions. The axial ends of the connecting rod 124 are respectively connected to the upper sleeve 122 and the lower sleeve 123. The plurality of connecting rods 124 extend at intervals along the circumferential direction of the lower sleeve 123. An exhaust port 121 is formed between two adjacent connecting rods 124, the bottom edge of the upper sleeve 122 and the top edge of the lower sleeve 123.

[0039] The upper sleeve 122 and lower sleeve 123, spaced apart from each other, are connected as a whole via four equally spaced connecting rods 124, forming four exhaust ports 121. Furthermore, the upper ends of the connecting rods 124 are connected to the inner wall of the upper sleeve 122, while the lower ends of the connecting rods 124 are connected to the inner wall of the lower sleeve 123, facilitating the fitting of the exhaust pipe 11 around the outer periphery of the adjustment sleeve 12. In practice, the upper sleeve 122, lower sleeve 123, and multiple connecting rods 124 can be secured by welding. In actual use, the lower sleeve 123 is always arranged in an inner-outer-outer arrangement with the exhaust pipe 11, ensuring that the adjustment sleeve 12 can be stably mounted on the exhaust pipe 11.

[0040] In some other embodiments, the adjustment sleeve 12 may also be a whole sleeve structure, and the exhaust port 121 is a through-hole structure opened on the side wall of the adjustment sleeve 12 .

[0041] The cover plate 13 is provided at the top end of the adjustment sleeve 12. The cover plate 13 can be fixed to the upper sleeve 122 by welding. Furthermore, the outer diameter of the cover plate 13 is larger than the outer diameter of the exhaust pipe 11, that is, the outer periphery of the cover plate 13 extends outwardly beyond the outer periphery of the exhaust pipe 11. Therefore, the cover plate 13 can prevent rainwater and foreign matter from falling, thereby improving the covering effect of the exhaust pipe 11. In this embodiment, the cover plate 13 is circular. In other embodiments, the cover plate 13 can also be polygonal, elliptical, etc., as long as the cover plate 13 can cover and be larger than the cross-sectional shape of the exhaust pipe 11.

[0042] Furthermore, the outer periphery of the cover plate 13 is bent downward to form a flange 131, which increases the strength of the cover plate 13, reduces deformation of the cover plate 13, and reduces the risk of cutting hands by the edge of the cover plate 13. In specific production, the cover plate 13 can be fixed to the upper sleeve 122 by welding.

[0043] Combine Figure 2 、 Figure 3 and Figure 4 In this embodiment, the locking structure 14 includes a limiting rod 141 provided on the exhaust pipe 11 and a first positioning groove 142 provided on the adjustment sleeve 12. The first positioning groove 142 is provided on the lower sleeve 123. The first positioning groove 142 includes a first through portion 1421 and a first positioning portion 1422 that intersect with each other. The opening 14211 of the first through portion 1421 faces upward and communicates with the exhaust port 121, allowing the limiting rod 141 to enter or exit the first through portion 1421. The first positioning portion 1422 extends along the circumference of the adjustment sleeve 12, with the opening of the first positioning portion 1422 facing the first through portion 1421. The adjustment sleeve 12 can rotate relative to the exhaust pipe 11, allowing the limiting rod 141 to enter and be positioned in the first positioning portion 1422, or to exit the first positioning portion 1422.

[0044] Specifically, the limiting rod 141 is fixed on the exhaust pipe 11, and the opening 14211 of the first through portion 1421 faces upward and is connected to the exhaust port 121. When exhaust is needed, the adjusting sleeve 12 is rotated to the position where the opening 14211 of the first through portion 1421 is upwardly facing the limiting rod 141, and then the adjusting sleeve 12 is lifted so that the limiting rod 141 can pass through the opening 14211 of the first through portion 1421 and enter the first positioning groove 142, and then can slide from the first positioning groove 142 into the first positioning portion 1422. The first positioning portion 1422 extends along the circumference of the adjusting sleeve 12, which can limit the up and down movement of the adjusting sleeve 12 relative to the exhaust pipe 11, thereby realizing the locking of the adjusting sleeve 12 and the exhaust pipe 11 in the up and down directions. At this time, the exhaust port 121 on the adjusting sleeve 12 is higher than the exhaust pipe 11, and the exhaust port 121 is opened. When exhaust is not needed, that is, the exhaust device 1 needs to be closed, the adjusting sleeve 12 is rotated to make the limiting rod 141 disengage from the first positioning portion 1422 and enter the first passing portion 1421, and then the adjusting sleeve 12 is lowered, and the limiting rod 141 disengages from the first positioning groove 142 along the first passing portion 1421, so that the side wall of the exhaust pipe 11 can block the exhaust port 121 on the adjusting sleeve 12, thereby realizing the shielding of the exhaust port 121, which is convenient and quick.

[0045] In fact, the first positioning groove 142 can also be set on the exhaust pipe 11, and the limiting rod 141 can be set on the adjusting sleeve 12. The opening 14211 of the first through portion 1421 faces upward and extends to the top of the exhaust pipe 11. The first positioning portion 1422 extends along the circumference of the exhaust pipe 11. By rotating and adjusting the upper and lower positions of the adjusting sleeve 12, the limiting rod 141 can slide into the first through portion 1421 and the first positioning portion 1422 in turn.

[0046] In this embodiment, the first through portion 1421 extends axially along the adjustment sleeve 12, eliminating the need for applying force to rotate the adjustment sleeve 12 when adjusting the vertical position of the adjustment sleeve 12. Furthermore, the first positioning portion 1422 extends horizontally, eliminating the need for additional vertical adjustment of the adjustment sleeve 12 when rotating the adjustment sleeve 12 to slide the limiting rod 141 relative to the first positioning portion 1422. An L-shaped first positioning groove 142 is formed between the first through portion 1421 and the first positioning portion 1422, facilitating adjustment of the adjustment sleeve 12. In practice, the first through portion 1421 may also extend obliquely upward, while the first positioning portion 1422 may also extend obliquely along the circumference of the adjustment sleeve 12.

[0047] Moreover, the circumferential dimension of the first passing portion 1421 is greater than the axial dimension of the first positioning portion 1422 , which facilitates the operation of the adjusting sleeve 12 and the entry of the limiting rod 141 into the first passing portion 1421 .

[0048] In some embodiments, the first passage 1421 extends downward to the bottom surface of the adjustment sleeve 12. This allows the operator to insert the first passage 1421 of the adjustment sleeve 12 into the position of the limit rod 141 without removing the limit rod 141, allowing the adjustment sleeve 12 to be directly connected to the exhaust pipe 11, facilitating operation. Alternatively, the first passage 1421 may not extend through the bottom surface of the adjustment sleeve 12. During installation, the adjustment sleeve 12 and the exhaust pipe 11 can be connected by removing the limit rod 141. After the two are connected, the limit rod 141 can be inserted into the exhaust pipe 11.

[0049] The adjustment sleeve 12 and the exhaust pipe 11 are cylindrical and can rotate relative to each other. Therefore, the first positioning groove 142 also includes a limiting portion 1423. The limiting portion 1423 is arranged above the first positioning portion 1422 and is connected to the first positioning portion 1422. Under the action of gravity, the bottom surface of the limiting portion 1423 is aligned with the top surface of the limiting rod 141. The limiting portion 1423 can be used to clamp the limiting rod 141 to limit the circumferential movement of the limiting rod 141, preventing the adjustment sleeve 12 from rotating or shifting relative to the exhaust pipe 11, thereby improving the positioning stability of the adjustment sleeve 12. In practice, the limiting portion 1423 can be arranged at the end of the first positioning portion 1422 away from the first passing portion 1421, or it can be arranged at a position other than the two ends of the first positioning portion 1422.

[0050] In this embodiment, two first positioning slots 142 are provided, symmetrically arranged on opposite sides of the adjustment sleeve 12. The axial ends of the limiting rod 141 extend through opposite sides of the exhaust pipe 11, and the axial ends of the limiting rod 141 can be respectively inserted into the two first positioning slots 142 on a one-to-one basis. The limiting rod 141 can be inserted into both first positioning slots 142 simultaneously, allowing the adjustment sleeve 12 to be adjusted along the limiting rod 141 or positioned on the limiting rod 141 through the first positioning slots 142 on opposite sides, thereby improving the adjustment stability and positioning stability of the adjustment sleeve 12.

[0051] Combine Figure 3 Furthermore, mounting through holes are provided on opposite sides of the exhaust pipe 11, and two mounting through holes are respectively passed through the axial ends of the limiting rod 141, and a limiting pin 1411 is passed through the part of the limiting rod 141 passing through the exhaust pipe 11. The two limiting pins 1411 on the limiting rod 141 limit the limiting rod 141 from falling off from the exhaust pipe 11 and facilitate the installation and disassembly of the limiting rod 141.

[0052] In addition, the limiting rod 141 can also be fixed to the exhaust pipe 11 by welding, or can be detachably positioned on the exhaust pipe 11 by threaded connection, clamping or nut fixing. The limiting rod 141 is positioned at the upper part of the side wall of the exhaust pipe 11.

[0053] In another embodiment, there may be two limiting rods 141 , which are disposed on opposite sides of the exhaust pipe 11 . The two limiting rods 141 can extend into the two first positioning slots 142 one by one.

[0054] Furthermore, the locking structure 14 also includes a second positioning groove 143, which is arranged on the upper sleeve 122. The second positioning groove 143 includes a second through portion 1431 and a second positioning portion 1432 that are connected to each other. The opening 14311 of the second through portion 1431 is downward and connected to the exhaust port 121, so that the limiting rod 141 can enter or exit the second through portion 1431. The second positioning portion 1432 extends along the circumference of the adjustment sleeve 12, and the opening of the second positioning portion 1432 faces the second through portion 1431, so that the limiting rod 141 can enter and be positioned in the second positioning portion 1432, or the limiting rod 141 can exit the second positioning portion 1432.

[0055] The second through portion 1431 and the second positioning portion 1432 are staggered to form an L-shaped second positioning groove 143. Figure 5When the exhaust port 121 needs to be closed, the adjusting sleeve 12 is adjusted so that the opening 14311 of the second through portion 1431 is downwardly facing the limiting rod 141, so that the limiting rod 141 can enter the second through portion 1431, and then the adjusting sleeve 12 is rotated to make the limiting rod 141 enter the second positioning portion 1432. Under the action of gravity, the adjusting sleeve 12 is positioned and hung on the limiting rod 141, thereby locking the adjusting sleeve 12 and the exhaust pipe 11. At this time, the exhaust port 121 is completely retracted into the exhaust pipe 11, and the side wall of the exhaust pipe 11 blocks the exhaust port 121 to prevent foreign matter from entering the exhaust pipe 11 through the exhaust port 121.

[0056] In this embodiment, the second through portion 1431 extends axially along the upper sleeve 122. The second positioning portion 1432 extends horizontally around the circumference of the upper sleeve 122, or extends obliquely upward in a direction away from the second through portion 1431 to prevent the limiting rod 141 from separating from the second positioning portion 1432 due to the weight of the adjustment sleeve 12. In practice, the second through portion 1431 may also extend obliquely upward.

[0057] Furthermore, the opening 14211 of the first through portion 1421 and the opening 14311 of the second through portion 1431 are opposite to each other in the vertical direction, so that in the process of opening and closing the exhaust port 121, the staff does not need to repeatedly rotate the adjustment sleeve 12, and can adjust the height position of the adjustment sleeve 12 straight up and down, so that the limiting rod 141 can directly enter the second through portion 1431 after detaching from the first through portion 1421, or directly enter the first through portion 1421 after detaching from the second through portion 1431, thereby facilitating the position replacement of the limiting rod 141 between the first positioning groove 142 and the second positioning groove 143.

[0058] Furthermore, two second positioning slots 143 are also provided, and the two second positioning slots 143 are centrally symmetrically arranged on opposite sides of the adjustment sleeve 12. Specifically, the limiting rod 141 can be simultaneously inserted into the two second positioning slots 143, so that the adjustment sleeve 12 can be adjusted along the limiting rod 141 or positioned on the limiting rod 141 through the second positioning slots 143 on the opposite sides, thereby improving the adjustment stability and positioning stability of the adjustment sleeve 12.

[0059] In addition, only one of the first positioning groove 142, the second positioning groove 143, and the limiting rod 141 can be provided, respectively. The inner and outer casing structures of the adjustment sleeve 12 and the exhaust pipe 11 restrict the movement trajectory of the exhaust pipe 11, and the first positioning groove 142, the second positioning groove 143, and the limiting rod 141 cooperate to lock the adjustment sleeve 12 in the position of opening and closing the exhaust port 121. In addition, only multiple of the first positioning groove 142, the second positioning groove 143, and the limiting rod 141 can be provided, as long as the positions of the first positioning groove 142, the second positioning groove 143, and the limiting rod 141 can correspond to each other.

[0060] In some other embodiments, the locking structure 14 may also be an existing replaceable structure such as a matching structure of a screw and a nut, a matching structure of a screw and a screw hole, or a matching structure of a pin and a hole.

[0061] The specific implementation process is as follows:

[0062] The exhaust pipe 11 is sleeved on the outer circumference of the adjusting sleeve 12. When exhaust is required, the openings 14211 of the first through parts 1421 on the opposite sides of the adjusting sleeve 12 are aligned with the limit rods 141 on the exhaust pipe 11, and then the adjusting sleeve 12 is driven to move upward, so that the limit rods 141 pass through the first positioning grooves 142 on the lower sleeve 123 until the adjusting sleeve 12 moves up to the position where the openings of the first positioning parts 1422 are opposite to the limit rods 141. By rotating the adjusting sleeve 12, the limit rods 141 slide into the first positioning parts 1422 and slide to the limit parts 1423 under the action of gravity to lock, preventing the adjusting sleeve 12 from rotating relative to the exhaust pipe 11, thereby achieving the locking of the adjusting sleeve 12 and the exhaust pipe 11. At this time, the exhaust passage 121 surrounded by the upper sleeve 122, the lower sleeve 123 and the adjacent connecting rods is higher than the exhaust pipe 11, so that the exhaust gas can stably pass through the exhaust pipe 11 upward and be discharged from the exhaust passage 121.

[0063] When exhaust is not needed, the adjusting sleeve 12 is first lifted upward to make the limiting portion 1423 disengage from the limiting rod 141, and then the adjusting sleeve 12 is rotated and lowered in sequence, and the limiting portion 1423 is separated from the first positioning portion 1422 and the first through portion 1421 in sequence and enters the position of the exhaust port 121, and then the adjusting sleeve 12 is further lowered to make the limiting rod 141 pass through the second through portions 1431 on opposite sides of the upper sleeve 122 until the adjusting sleeve 12 moves down to the opening of the second positioning portion 1432 facing the limiting rod 141. position, by rotating the adjusting sleeve 12, the limiting rod 141 slides into the second positioning portion 1432, and the exhaust port 121 is now completely downwardly immersed in the exhaust pipe 11, so that the side wall of the exhaust pipe 11 blocks the exhaust port 121, thereby closing the exhaust port 121 and completing the covering of the exhaust pipe 11 to prevent foreign matter from entering the exhaust pipe 11. At the same time, when the exhaust is closed, the position of the cover plate 13 and the adjusting sleeve 12 can be lowered to reduce the phenomenon that the protruding size of the exhaust equipment 1 affects the transportation of the container 2.

[0064] When the adjustment sleeve 12 needs to be removed or installed on the exhaust pipe 11, the limiting rod 141 on the exhaust pipe 11 is aligned with the first through portion 1421 in the vertical direction, so that the adjustment sleeve 12 can be directly inserted into the exhaust pipe 11 downward or directly separated from the exhaust pipe 11 upward.

[0065] Reference Figure 6The exhaust pipe 11 is provided at the top of the box body 21 and passes through the box body 21 upward. The interior of the exhaust pipe 11 is connected to the inner cavity of the box body 21. By lifting the adjusting sleeve 12, the exhaust port 121 on the adjusting sleeve 12 is higher than the exhaust pipe 11. The locking structure 14 is used to lock the adjusting sleeve 12 on the exhaust pipe 11, so that the exhaust gas can pass through the exhaust pipe 11 and be discharged from the exhaust port 121. When exhaust is not needed, the locking structure 14 is released to lock the adjusting sleeve 12, and the adjusting sleeve 12 is driven to move downward until the side wall of the exhaust pipe 11 can cover the exhaust port 121, thereby covering the exhaust pipe 11 and preventing foreign matter from entering the exhaust pipe 11. At the same time, when the exhaust is closed, the position of the cover plate 13 and the adjusting sleeve 12 can be lowered to reduce the phenomenon that the transportation of the container 2 is affected by the protruding size of the exhaust equipment 1.
