[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] It should be noted that when an element is referred to as being "disposed on" another element, it may be directly on the other element or indirectly on the other element. It should be understood that the terms "length", "width", "upper", "lower", "front", "back", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0030] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "several" is two or more, unless otherwise clearly and specifically defined.

[0031] Please also read Figures 1 to 3 Now, the exhaust device for continuous production of filling process provided by the utility model is described. The exhaust device for continuous production of filling process includes a blower 1, a guide pipe 2 and a movable plug 4; the air inlet end of the blower 1 is connected to an exhaust pipe 11, and the exhaust end of the blower 1 is used to extend to the outdoors; the exhaust pipe 11 is used to communicate with the filling production line 10, and the blower 1 is used to form a negative pressure in the exhaust pipe 11 to discharge the steam in the exhaust pipe 11; one end of the guide pipe 2 is connected to the exhaust pipe 11, and the other end extends downward in the vertical direction; the lower end of the guide pipe 2 is provided with a buffer cavity 3 that passes through the guide pipe 2 from top to bottom, and the middle cross-sectional size of the buffer cavity 3 is larger than the cross-sectional size at both ends; the movable plug 4 is limited in the buffer cavity 3 and is slidably arranged in the vertical direction; under the action of the negative pressure of the exhaust pipe 11, the movable plug 4 has a closed state of blocking the upper port of the buffer cavity 3, and when the condensed water gathers in the guide pipe 2 to a first preset length, the movable plug 4 also has an open state of sliding downward to the upper port away from the buffer cavity 3.

[0032] It should be understood that when the blower 1 is working, a negative pressure will be formed in the exhaust duct 11. Since the exhaust duct 11 is connected to the upper end of the guide duct 2, the guide duct 2 is also in a negative pressure state. Therefore, the movable plug 4 is adsorbed on the upper end of the buffer cavity 3 under the action of the upper and lower pressure differences, and the movable plug 4 is in a closed state; because the movable plug 4 is limited in the buffer cavity 3, it will not be adsorbed into the exhaust duct 11 under the action of the pressure difference.

[0033] In addition, during the discharge process, the high-humidity and hot gas discharged from the exhaust pipe 11 will partially condense into liquid to form condensed water, and the condensed water will flow downward into the guide pipe 2 under the action of gravity. When the condensed water gradually accumulates and accumulates to a preset length in the guide pipe 2, the weight of the accumulated condensed water is sufficient to balance the pressure difference and press the movable plug 4 to slide downward, thereby putting the movable plug 4 in an open state, so that the condensed water is discharged downward, and after the condensed water is discharged, the movable plug 4 moves up again under the action of the pressure difference to form a closed state.

[0034] Preferably, the movable plug 4 is configured as a hollow structure and is made of antibacterial material to avoid bacterial contamination.

[0035] Exemplarily, the guide pipe 2 is a pipe with a diameter less than 100 mm. Preferably, the guide pipe 2 is a stainless steel pipe with a diameter of 32 mm.

[0036] Compared with the prior art, the exhaust device for continuous production of filling process provided by the utility model can exhaust high-humidity and hot gas to the outside through the air blower 1, and connect the guide pipe 2 to the exhaust pipe 11 so that the condensed water in the exhaust pipe 11 can be discharged through the guide pipe 2; and the lower end of the guide pipe 2 is provided with a buffer cavity 3 and a movable plug 4, when the movable plug 4 slides up and down in the buffer cavity 3, the buffer cavity 3 can be opened or closed to ensure the normally closed state of the guide pipe 2, and when the accumulated amount of condensed water reaches a preset length, the buffer cavity 3 is opened, thereby avoiding the problem of external impurities entering or causing bacterial contamination, thereby improving the safety of the drug filling production process.

[0037] See also Figure 2 or Figure 3 In some possible embodiments, the movable plug 4 includes a first conical section 41 and a transition section 42; the first conical section 41 is arranged near the upper port of the buffer chamber 3, and the cross-sectional size gradually increases from top to bottom; a first annular outlet 411 is formed between the first conical section 41 and the upper port of the buffer chamber 3; the transition section 42 is connected to the lower end of the first conical section 41; an annular channel 421 is left between the outer peripheral surface of the transition section 42 and the inner wall of the buffer chamber 3; wherein, when the movable plug 4 is in a closed state, the first annular outlet 411 is closed; when the movable plug 4 slides downward to an open state, the first annular outlet 411 increases, and condensed water enters the annular channel 421 from the first annular outlet 411.

[0038] In order to achieve the closed state of the movable plug 4, the upper end of the movable plug 4 is set to a first conical section 41 structure in the present application. When the movable plug 4 slides downward, the first annular outlet 411 gradually increases; and an annular channel 421 is always left between the transition section 42 and the buffer chamber 3 so that condensed water can be discharged downward from the annular channel 421.

[0039] See also Figure 2 or Figure 3 In some embodiments, the movable plug 4 also includes a second conical section 43 connected to the bottom of the transition section 42, the cross-sectional size of the second conical section 43 gradually decreases from top to bottom, and a second annular outlet 431 is formed between the second conical section 43 and the lower port of the buffer chamber 3; wherein, when the movable plug 4 is in a closed state, the second annular outlet 431 is opened; when the movable plug 4 slides downward to an open state, the second annular outlet 431 is reduced, and condensed water is discharged downward from the first annular outlet 411 through the annular channel 421 and the second annular outlet 431.

[0040] A second conical section 43 is provided to form a second annular outlet 431 between the lower end of the movable plug 4 and the buffer chamber 3, and during the sliding movement of the movable plug 4, the second annular outlet 431 gradually decreases but is not completely closed, so that part of the condensed water enters the buffer chamber 3 for buffering, and part of the condensed water is directly discharged downward from the buffer chamber 3 from the second annular outlet 431.

[0041] See also Figure 2 As a specific implementation in the present application, the elastic member 5 is not provided at the lower port of the buffer chamber 3. Even if the second annular outlet 431 is closed, since the condensed water in the guide tube 2 has partially flowed into the annular channel 421, the weight of the condensed water on the upper end of the movable plug 4 is not enough to balance the negative pressure in the exhaust pipe 11. The movable plug 4 will still slide upward to a closed state. At this time, the second annular outlet 431 is opened, and the condensed water in the annular channel 421 is discharged through the second annular outlet 431.

[0042] See also Figure 3 As another specific implementation in the present application, an elastic member 5 is further provided at the lower port of the buffer chamber 3 , and the elastic member 5 is sleeved on the lower end of the movable plug 4 .

[0043] An elastic member 5 is provided to support between the lower end of the movable plug 4 and the lower port of the buffer chamber 3, thereby preventing the movable plug 4 from sliding down to the second annular outlet 431 for closure, thereby preventing the discharge of condensed water from being affected; at the same time, condensed water is prevented from accumulating in the buffer chamber 3, thereby further ensuring that the flow path of the condensed water is normal.

[0044] It should be understood that the elastic member 5 is sleeved on the second conical section 43 so that the outer peripheral surface of the second conical section 43 cannot be closed at the lower port of the buffer chamber 3, thereby ensuring that the second annular outlet 431 is never completely closed to facilitate the discharge of condensed water.

[0045] See also Figure 2 or Figure 3In some embodiments, a first guide column 44 is provided at the upper end of the first conical section 41, and the first guide column 44 is slidably connected to the lower end of the guide tube 2 along the vertical direction; wherein the diameter of the first guide column 44 is smaller than the inner diameter of the guide tube 2.

[0046] The first guide column 44 is provided to prevent the movable plug 4 from deviating when sliding up and down, thereby preventing the closing and opening of the first annular outlet 411 from being affected.

[0047] See also Figure 1 In some possible embodiments, a drainage tube 6 is further provided at the lower end of the buffer chamber 3, and the upper end of the drainage tube 6 is communicated with the buffer chamber 3, and the lower end is extended downward.

[0048] The drainage pipe 6 is provided to drain the condensed water in the buffer chamber 3 downwards, so as to avoid the water flow affecting the wall structure when directly discharged.

[0049] See also Figure 1 In some embodiments, a second guide column 45 is provided at the lower end of the movable plug 4, and the second guide column 45 is slidably connected to the upper end of the drainage tube 6 along the vertical direction; wherein the diameter of the second guide column 45 is smaller than the inner diameter of the drainage tube 6.

[0050] Specifically, a second guide column 45 is provided at the lower end of the second conical section 43. By providing the second guide column 45, it can be further ensured that the path of the movable stopper 4 sliding up and down does not deviate, thereby improving the guiding stability of the movable stopper 4 sliding.

[0051] See also Figure 1 , illustratively, the lower end of the drainage pipe 6 is connected to a liquid collecting tank 7. By setting the liquid collecting tank 7, the discharged condensed water can be recovered in time, so as to facilitate reuse, and at the same time, the condensed water can be prevented from flowing to the ground, causing the ground to be slippery and affecting the safety of employees.

[0052] See also Figure 1 , exemplarily, a pressure sensor 8 is provided on the movable plug 4.

[0053] It should be noted that the pressure sensor 8 adopts a wireless pressure sensor 8, which can record and transmit the pressure condition on the active plug 4; by setting the pressure sensor 8, it is possible to monitor the pressure condition on the active plug 4, and to facilitate the analysis and recording of the discharge of condensed water through the pressure condition.

[0054] See also Figure 1 In some embodiments, an intelligent regulating valve 9 is also provided on the drainage tube 6 , and the intelligent regulating valve 9 is wirelessly connected to the pressure sensor 8 .

[0055] It should be understood that the intelligent regulating valve 9 is used to control the on-off of the drainage tube 6 to prevent foreign matter from entering the drainage tube 6 and causing bacterial contamination.

[0056] By setting the intelligent regulating valve 9 and wirelessly connecting the intelligent regulating valve 9 with the pressure sensor 8, the intelligent regulating valve 9 can obtain the pressure condition of the active plug 4 in time, thereby conveniently controlling the opening and closing of the intelligent regulating valve 9.
