[0045] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0046] Unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains.

[0047] Currently, cleaning a sterile room typically requires manually disassembling all removable components, followed by cleaning of these components and the sterile room itself. This process is time-consuming, and the cleaning effectiveness varies depending on the operator, making the cleaning process and results unpredictable.

[0048] According to an embodiment of this disclosure, a filling apparatus is provided, the filling apparatus including a sterile chamber, the sterile chamber including at least one partition wall and a cleaning device. The partition wall is configured to divide the sterile chamber into at least two working areas along a first direction; the cleaning device includes at least one cleaning component configured to rotate to clean at least one of the at least two working areas; wherein the partition wall has an opening area penetrating the partition wall, the opening area being configured to accommodate the cleaning component.

[0049] In the filling equipment provided in the above-described embodiments of this disclosure, by setting an opening area in the isolation wall for accommodating cleaning components, automatic cleaning of at least one of the at least two working areas can be achieved, which not only saves manpower and resources, but also makes the cleaning process simpler, more efficient and controllable.

[0050] The present disclosure will now be described through specific embodiments. To keep the following description of the embodiments of the present disclosure clear and concise, detailed descriptions of known functions and components may be omitted. When any component of an embodiment of the present disclosure appears in more than one drawing, the component may be represented by the same reference numerals in each drawing.

[0051] Figure 1 This is a schematic diagram of the structure of the filling equipment according to an embodiment of the present disclosure. Figure 1 . Figure 2 This is a schematic diagram of the structure of the filling equipment according to an embodiment of the present disclosure. Figure 2 . Figure 3This is a schematic diagram of the structure of the filling equipment according to an embodiment of the present disclosure. Figure 3 .

[0052] For example, such as Figures 1 to 3 As shown, the filling equipment includes a sterile chamber 1, which includes at least one partition wall configured to divide the sterile chamber 1 into at least two working areas along a first direction (e.g., the x-direction shown in the figure). For example, the at least one partition wall includes a first partition wall 100 configured to divide the sterile chamber 1 into a first working area 10 and a second working area 20 along the x-direction, and the at least two working areas include the first working area 10 and the second working area 20. For example, the at least two working areas may include a second working area 20 and a third working area 30, and the at least one partition wall may also include a second partition wall 200 configured to divide the sterile chamber 1 into a second working area 20 and a third working area 30 along the x-direction. The first working area 10, the second working area 20, and the third working area 30 are arranged sequentially along the x-direction, and these three working areas have different functions. In this embodiment of the disclosure, "at least one isolation wall" can refer to either the first isolation wall 100 located between the first work area 10 and the second work area 20, or the second isolation wall 200 located between the second work area 20 and the third work area 30, or both the first isolation wall 100 and the second isolation wall 200. This embodiment of the disclosure does not limit the term to either. "At least two work areas" includes two, three, or more work areas. When it includes two work areas, it can include either the first work area 10 and the second work area 20, or the second work area 20 and the third work area 30. This embodiment of the disclosure does not limit the term to either.

[0053] For example, filling equipment may also include a conveying device (not shown) that is carried out along the conveying direction (e.g. Figure 1 The conveyor moves in the x-direction shown. The conveyor is equipped with multiple rows of receiving units C (also called cells), each receiving unit C containing a packaging container P with a single-sided opening (also called a top opening) (see...). Figure 1As the conveying device moves along the x-direction, the receiving unit C also moves accordingly. The packaging container P, located in the receiving unit C, sequentially passes through three different working areas to process the packaging container P separately. For example, the first working area 10 is a pre-treatment area, equipped with a pre-treatment device configured to perform at least one pre-treatment operation on the packaging container P, including preheating, sterilization, and drying. In some embodiments, at least one of the preheating gas, drying gas, and sterilizing gas is introduced into the packaging container P through the top opening. For example, the second working area 20 is a filling area, equipped with a filling device configured to perform a filling operation on the packaging container P. In some embodiments, the filling device fills liquid food into the packaging container P through the top opening. The third working area 30 is a sealing area. The sealing area is equipped with a sealing device 300 configured to fold and seal the top opening of the filled packaging container P.

[0054] For example, the sterile room 1 also includes a cleaning device comprising at least one cleaning component configured to rotate for cleaning at least one of at least two work areas; wherein the partition wall has an opening area extending through the partition wall, the opening area being configured to accommodate the cleaning component.

[0055] In this embodiment of the disclosure, "at least one cleaning component" can refer to either the first cleaning component 102 or the second cleaning component 202 (details of the first cleaning component 102 and the second cleaning component 202 are described below), or it can refer to both the first cleaning component 102 and the second cleaning component 202. The first cleaning component 102 will be described in detail below.

[0056] Figure 4 This is a partial structural diagram of the filling equipment according to an embodiment of the present disclosure. Figure 1 .like Figure 3 and Figure 4 As shown, at least one cleaning component includes a first cleaning component 102, which is rotatable to clean at least one of a first working area 10 and a second working area 20. For example, a first partition wall 100 has a first opening area OA1 extending through the first partition wall 100, which is configured to accommodate the first cleaning component 102. In this embodiment, by creating the first opening area OA1 in the first partition wall 100, the first working area 10 and the second working area 20 are connected to each other at the first opening area OA1. Thus, when the first cleaning component 102 in the first opening area OA1 rotates, automatic cleaning of the first working area 10 and the second working area 20 can be achieved without disassembling the parts to be cleaned in the first working area 10 and the second working area 20, saving manpower and material costs and making the cleaning process simpler, more efficient, and more controllable.

[0057] In some cases, if the first cleaning component 102 is not located on the first isolation wall 100 between the first work area 10 and the second work area 20 (for example, located inside the first work area 10 or the second work area 20), one or more cleaning components need to be set in each work area. These cleaning components are responsible for the automatic cleaning of the work area where the cleaning component is located, but cannot clean other work areas. This results in a large total number of cleaning components, which is not conducive to controlling the cleaning effect and also increases the cleaning cost.

[0058] In this embodiment of the disclosure, by placing the first cleaning component 102 on the first isolation wall 100 between the first working area 10 and the second working area 20, cleaning of the first working area 10 and the second working area 20 can be achieved using only one first cleaning component 102. Compared to the above cases, this reduces the total number of cleaning components and the cleaning cost.

[0059] For example, the isolation wall includes a first side and a second side arranged opposite to each other in the x-direction, with at least two work areas, one work area located on the first side and the other work area located on the second side; the cleaning component is configured to clean one work area when rotated to the first side and to clean the other work area when rotated to the second side.

[0060] Figure 5 This is a partial structural diagram of the filling equipment according to an embodiment of the present disclosure. Figure 2 .like Figure 5 As shown, the first isolation wall 100 includes a first side S11 and a second side S12 of the first isolation wall arranged opposite to each other in the x-direction. The first working area 10 is located on the first side S11 of the first isolation wall, and the second working area 20 is located on the second side S12 of the first isolation wall. The first cleaning component 102 is configured to clean the first working area 10 (i.e., the state shown in the figure, where the first working area 10 is, for example, a pretreatment area) when rotated to the first side S11 of the first isolation wall, and to clean the second working area 20 (for example, the second working area 20 is a filling area) when rotated to the second side S12 of the first isolation wall. In this way, by controlling the rotation direction or rotation angle of the first cleaning component 102, automatic cleaning of the pretreatment area and the filling area can be achieved respectively.

[0061] For example, the partition wall includes two wall portions, which are spaced apart from each other in a second direction (e.g., the y-direction shown in the figure) to form an opening area, and the second direction intersects the first direction. In this embodiment of the disclosure, the second direction and the first direction are described as being perpendicular to each other. It is understood that in other embodiments, the second direction and the first direction may not be perpendicular to each other; for example, they may form an acute angle of less than 90 degrees, and the purpose of the present invention can still be achieved.

[0062] refer to Figure 4 and Figure 5The first isolation wall 100 includes a first wall portion 100a and a second wall portion 100b, which are spaced apart in the y-direction to form a first opening region OA1. That is, the first opening region OA1 is located between the first wall portion 100a and the second wall portion 100b in the y-direction. To facilitate the accommodation of the first cleaning component 102 and allow it to rotate freely, the width of the first opening region OA1 in the y-direction is greater than the width of the first cleaning component 102 in the y-direction. For example, the width of the first opening region OA1 in the y-direction is greater than the width of the first cleaning component 102 in the y-direction, and the difference between the two can be less than any given positive number, which is more conducive to achieving the isolation effect between the two work areas. In some embodiments, such as... Figure 5 As shown, the first wall portion 100a and the second wall portion 100b are aligned along the same straight direction (e.g., the y-direction). This avoids changing the position of the first partition wall 100 in the existing equipment, maintaining the spatial division of the filling area and the packaging area, and saving on the cost of modifying the existing equipment. For example, the cleaning assembly includes a cleaning conduit located in the opening area, the cleaning conduit being configured to rotate about its own axis. Reference Figure 3 and Figure 4 The first cleaning component 102 includes a first cleaning conduit 104 located in the first opening region OA1. The first cleaning conduit 104 has a first axis Z104 and is configured to rotate about the first axis Z104. Since the first cleaning conduit 104 is arranged in the x-direction between the pretreatment area and the filling area and can rotate about its own first axis Z104, the structure of the cleaning component itself can be further simplified while ensuring automatic cleaning of the pretreatment area and the filling area.

[0063] For example, a cleaning pipeline includes a main pipe and a nozzle disposed on the main pipe. The main pipe is configured to deliver cleaning liquid, and the nozzle is configured to spray the delivered liquid. The main pipe has a recess, and the nozzle is disposed within the recess. (Reference) Figure 4 The first cleaning conduit 104 includes a first main pipe 1041 and a first nozzle 1042 disposed on the first main pipe 1041. The first main pipe 1041 is configured to deliver cleaning liquid, and the first nozzle 1042 is configured to spray the delivered liquid. The first main pipe 1041 is provided with a first recess CP1, and the first nozzle 1042 is disposed in the first recess CP1. By disposing the first nozzle 1042 in the first recess CP1, the following beneficial effects can be achieved: 1) It can prevent the first nozzle 1042 from hitting the surrounding isolation wall (e.g., the first wall portion 100a and the second wall portion 100b) when the first main pipe 1041 rotates, thereby avoiding mechanical damage that the first cleaning assembly 102 may cause during the cleaning process. 2) It simplifies the structure of the isolation wall. 3) When the first nozzle 1042 is, for example, in the position of... Figure 4When the positions shown are as indicated, the distance between the first wall portion 100a and the first cleaning component 102 (e.g., the first main pipe 1041) will be very small, and the distance between the second wall portion 100b and the first cleaning component 102 (e.g., the first main pipe 1041) will also be very small, which is conducive to the distribution of sterile air in the sterile room, while better separating the first work area 10 and the second work area 20.

[0064] For example, there may be multiple nozzles, and the main pipe includes a first mounting end, a second mounting end, and an intermediate section located between the first and second mounting ends. The nozzle closest to either the first or second mounting end is defined as an end nozzle, and the nozzle located between the two end nozzles is defined as an intermediate nozzle. The end nozzles have a first angle relative to the axial direction of the main pipe, and the intermediate nozzles have a second angle relative to the axial direction of the main pipe. The first and second angles are not equal. It is understood that in other embodiments of this disclosure, the first and second angles may be set to be equal as needed.

[0065] Figure 6 This is a schematic diagram of the structure of the first cleaning component according to an embodiment of the present disclosure. Figure 1 . Figure 7 This is a schematic diagram of the structure of the first cleaning component according to an embodiment of the present disclosure. Figure 2 .like Figure 6 and Figure 7 As shown, there are multiple first nozzles 1042. The first main pipe 1041 includes a first mounting end 1041a, a second mounting end 1041b, and a first intermediate section 1041c located between the first mounting end 1041a and the second mounting end 1041b. The first nozzle 1042 closest to the first mounting end 1041a or the second mounting end 1041b is defined as the first end nozzle 1042a, and the first nozzle 1042 located between the two first end nozzles 1042a is defined as the first intermediate nozzle 1042b. The first end nozzle 1042a has a first included angle α1 relative to the axial direction of the first main pipe 1041 (i.e., the rotation axis Z104 of the first cleaning pipeline 104), and the first intermediate nozzle 1042b has a second included angle α2 relative to the axial direction of the first main pipe 1041. The first included angle α1 and the second included angle α2 are not equal. In this embodiment, the first main pipe 1041 can be fixedly installed in the sterile chamber 1 using the first mounting end 1041a and the second mounting end 1041b, thereby improving the stability of the first main pipe 1041 during rotation. This is achieved by setting the first included angle α1 and the second included angle α2 to be unequal (e.g., ...). Figure 7The second included angle α2 shown is greater than the first included angle α1, which helps to improve the cleaning effect on the vertical isolation wall of the sterile room 1 near the first mounting end 1041a and the second mounting end 1041b (for example, the first main pipe 1041 is mounted to the vertical isolation wall through the first mounting end 1041a and the second mounting end 1041b). In some embodiments, the second included angle α2 is a right angle and the first included angle α1 is an acute angle.

[0066] For example, there may be multiple first intermediate nozzles 1042b, which are arranged at equal intervals. This ensures the uniformity of the cleaning effect. It is understood that in the embodiments of this disclosure, the multiple first intermediate nozzles 1042b may also be arranged at non-equal intervals. Those skilled in the art can set the spacing and number of the multiple first intermediate nozzles 1042b according to actual needs, and the embodiments of this disclosure do not limit this.

[0067] The second cleaning component 202 will be described in further detail below.

[0068] Figure 8 This is a partial structural diagram of the filling equipment according to an embodiment of the present disclosure. Figure 3 Combining Figure 3 and Figure 8 As shown, for example, the second isolation wall 200 has a second opening area OA2 that penetrates the second isolation wall 200, and the second opening area OA2 is configured to accommodate the second cleaning component 202. In this embodiment, by opening the second opening area OA2 on the second isolation wall 200, the second working area 20 and the third working area 30 are connected to each other at the second opening area OA2. In this way, when the second cleaning component 202 in the second opening area OA2 rotates, the second working area 20 and the third working area 30 can be automatically cleaned respectively without disassembling the parts to be cleaned in the second working area 20 and the third working area 30. This not only saves manpower and material costs, but also makes the cleaning process simpler, more efficient and controllable.

[0069] In some cases, if the second cleaning component 202 is not installed on the second isolation wall 200 between the second work area 20 and the third work area 30 (for example, installed inside the second work area 20 or the third work area 30), one or more cleaning components need to be installed in each work area. These cleaning components are responsible for the automatic cleaning of the work area where the cleaning component is located, but cannot clean other work areas. This results in a large total number of cleaning components, which is not conducive to controlling the cleaning effect and also increases the cleaning cost.

[0070] In this embodiment, by placing the second cleaning component 202 on the second isolation wall 200 between the second working area 20 and the third working area 30, cleaning of both the second working area 20 and the third working area 30 can be achieved using only one second cleaning component 202. Compared to the above methods, this reduces the total number of cleaning components and the cleaning cost.

[0071] Figure 9 This is a partial structural diagram of the filling equipment according to an embodiment of the present disclosure. Figure 4 .like Figure 9 As shown, the second isolation wall 200 includes a first side S21 and a second side S22 of the second isolation wall arranged opposite to each other in the x-direction. The second working area 20 is located on the first side S21 of the second isolation wall, and the third working area 30 is located on the second side S22 of the second isolation wall. The second cleaning component 202 is configured to clean the second working area 20 (i.e., the state shown in the figure, where the second working area 20 is, for example, a filling area) when rotated to the first side S21 of the second isolation wall, and to clean the third working area 30 (for example, the third working area 30 is a packaging area) when rotated to the second side S22 of the second isolation wall. In this way, by controlling the rotation direction or rotation angle of the second cleaning component 202, it is beneficial to achieve automatic cleaning of the filling area and the packaging area respectively.

[0072] refer to Figure 8 and Figure 9 The second partition wall 200 includes a third wall portion 200a and a fourth wall portion 200b, which are spaced apart from each other in the y-direction to form a second opening region OA2. That is, the second opening region OA2 is located between the third wall portion 200a and the fourth wall portion 200b in the y-direction. To facilitate the accommodation of the second cleaning component 202 and to allow the second cleaning component 202 to rotate freely, the width of the second opening region OA2 in the y-direction is greater than the width of the second cleaning component 202 in the y-direction. In some embodiments, such as... Figure 9 As shown, the third wall portion 200a and the fourth wall portion 200b are aligned along the same straight direction (e.g., the y-direction). This does not change the position of the first isolation wall 100 in the existing equipment, thus maintaining the division of the filling area and the packaging area in the existing equipment and saving the cost of modifying the existing equipment.

[0073] For example, refer to Figure 3The second cleaning assembly 202 includes a second cleaning conduit 204 located in the second opening region OA2. The second cleaning conduit 204 has a second axis Z204 and is configured to rotate about the second axis Z204. Since the second cleaning conduit 204 is arranged in the x-direction between the filling area and the packaging area and can rotate about its own second axis Z204, the structure of the cleaning assembly itself can be further simplified while ensuring automatic cleaning of the filling area and the packaging area.

[0074] For example, refer to Figure 8 The second cleaning conduit 204 includes a second main pipe 2041 and a second nozzle 2042 disposed on the second main pipe 2041. The second main pipe 2041 is configured to deliver cleaning liquid, and the second nozzle 2042 is configured to spray the delivered liquid. The second main pipe 2041 is provided with a second recess CP2, and the second nozzle 2042 is disposed in the second recess CP2. By disposing the second nozzle 2042 in the second recess CP2, the following beneficial effects can be achieved: 1) It can prevent the second nozzle 2042 from hitting the surrounding isolation walls (e.g., the third wall portion 200a and the fourth wall portion 200b) when the second main pipe 2041 rotates, thereby avoiding mechanical damage that the second cleaning assembly 202 may cause during the cleaning process. 2) It simplifies the structure of the isolation walls. 3) When the second nozzle 2042 is, for example, in the position of... Figure 8 When the positions shown are as indicated, the distance between the third wall portion 200a and the second cleaning component 202 (e.g., the second main pipe 2041) will be small, and the distance between the fourth wall portion 200b and the second cleaning component 202 (e.g., the second main pipe 2041) will also be small, which is conducive to the distribution of sterile air in the sterile room, while better separating the second work area 20 and the third work area 30.

[0075] In this embodiment, the first cleaning component 102 and the second cleaning component 202 may have the same or different structures. When their structures are the same, the manufacturing process can be simplified, and the cleaning process can be easily controlled. This embodiment is illustrated using the example of two components having the same structure.

[0076] Figure 10 This is a schematic diagram of the structure of the second cleaning component according to an embodiment of the present disclosure. Figure 1 . Figure 11 This is a schematic diagram of the structure of the second cleaning component according to an embodiment of the present disclosure. Figure 2 .like Figure 10 and Figure 11As shown, there are multiple second nozzles 2042. The second main pipe 2041 includes a third mounting end 2041a, a fourth mounting end 2041b, and a second intermediate section 2041c located between the third mounting end 2041a and the fourth mounting end 2041b. The second nozzle 2042 closest to the third mounting end 2041a or the fourth mounting end 2041b is defined as the second end nozzle 1042a, and the second nozzle 2042 located between the two second end nozzles 1042a is defined as the second intermediate nozzle 1042b. The second end nozzle 1042a has a third included angle α3 relative to the axial direction of the second main pipe 2041 (e.g., the rotation axis of the second cleaning pipeline 204), and the second intermediate nozzle 1042b has a fourth included angle α4 relative to the axial direction of the second main pipe 2041. The third included angle α3 and the fourth included angle α4 are not equal. In this embodiment, the second main pipe 2041 can be fixedly installed in the sterile chamber 1 using the third mounting end 2041a and the fourth mounting end 2041b, thereby improving the stability of the second main pipe 2041 during rotation. This is achieved by setting the third included angle α3 and the fourth included angle α4 to be unequal (e.g., ...). Figure 7 The fourth included angle α4 shown is greater than the third included angle α3, which is beneficial for improving the cleaning effect on the vertical isolation wall of the sterile room 1 near the third mounting end 2041a and the fourth mounting end 2041b (for example, the second main pipe 2041 can be mounted to the vertical isolation wall through the third mounting end 2041a and the fourth mounting end 2041b). In some embodiments, the fourth included angle α4 is a right angle and the third included angle α3 is an acute angle.

[0077] For example, there may be multiple second intermediate nozzles 1042b, arranged at equal intervals. This ensures the uniformity of the cleaning effect. It is understood that in this embodiment, the multiple second intermediate nozzles 1042b may also be arranged at non-equal intervals. Those skilled in the art can set the spacing and number of the multiple second intermediate nozzles 1042b according to actual needs, and this embodiment does not limit this.

[0078] For example, the filling equipment also includes at least one pre-laminar flow structure and at least one laminar flow structure spaced apart in the y-direction. The pre-laminar flow structure is configured to guide the sterile air in the sterile chamber 1. Combined with... Figure 1 and Figure 2 At least one pre-laminar flow structure includes, for example, a first pre-laminar flow structure A1 located in a first working area 10 and a second pre-laminar flow structure A2 located in a second working area 20. The laminar flow structures are configured to redirect sterile air to increase the diffusion or delivery range of the sterile air. Figure 1 As shown, at least one laminar flow structure includes, for example, a first laminar flow structure B1 located in the first working area 10 and a second laminar flow structure B2 located in the second working area 20. Figure 4As shown, in the y-direction, the first cleaning component 102 is located between the first pre-laminar structure A1 and the first laminar structure B1. Figure 8 As shown, in the y-direction, the second cleaning component 202 is located between the second pre-laminar flow structure A2 and the second laminar flow structure B2. By placing the first cleaning component 102 between the first pre-laminar flow structure A1 and the first laminar flow structure B1, automatic cleaning of at least the first pre-laminar flow structure A1 and the first laminar flow structure B1 in the first working area 10, and the second pre-laminar flow structure A2 and the second laminar flow structure B2 in the second working area 20 can be achieved, thus eliminating the need for manual disassembly of the aforementioned components before cleaning. This not only saves manpower and material costs but also makes the cleaning process simpler, more efficient, and more controllable. Similarly, by placing the second cleaning component 202 between the second pre-laminar flow structure A2 and the second laminar flow structure B2, automatic cleaning of at least the second pre-laminar flow structure A2 and the second laminar flow structure B2 in the second working area 20, and the third pre-laminar flow structure A3 and the third laminar flow structure B3 (details described below) in the third working area 30 can be achieved, eliminating the need for manual disassembly of the aforementioned components before cleaning. This not only saves manpower and material costs but also makes the cleaning process simpler, more efficient, and more controllable.

[0079] For example, such as Figure 2 As shown, at least one laminar flow structure further includes a third laminar flow structure B3 located in the third working area 30; in the y-direction, the third laminar flow structure B3 is closer to the top of the sterile chamber 1 than the first laminar flow structure B1 and the second laminar flow structure B2, to accommodate the sealing device 300. Figure 8 and Figure 9 As shown, the third laminar flow structure B3 is provided with a third opening region OA3 for accommodating the second cleaning component 202. The third opening region OA3 and the second opening region OA2 are configured to jointly accommodate the second cleaning component 202. By creating the third opening region OA3 on the third laminar flow structure B3, the accommodating space for the second cleaning component 202 can be increased without changing the existing position of the third laminar flow structure B3, which is beneficial for achieving automatic cleaning of the two sub-working areas in the third working area 30. It is understood that, in other embodiments of this disclosure, depending on actual needs, the third laminar flow structure B3 may also be configured to be flush with at least one of the first laminar flow structure B1 and the second laminar flow structure B2, or configured to be lower than at least one of the first laminar flow structure B1 and the second laminar flow structure B2.

[0080] For example, such as Figure 9As shown, the third laminar flow structure B3 extends along the x-direction and divides the third working area 30 in the y-direction into a first sub-working area 30a and a second sub-working area 30b. The second cleaning component 202 is also configured to be rotatable to clean at least one of the first sub-working area 30a and the second sub-working area 30b. In some embodiments, when the second cleaning component 202 rotates to a first position (e.g., towards...), Figure 9 When the second cleaning component 202 rotates to the second position (e.g., towards the upper right), it can automatically clean the first sub-work area 30a. Figure 9 When the area is located in the lower right corner, automatic cleaning of the second sub-work area 30b can be achieved.

[0081] In this embodiment, the specific constructions of the first laminar flow structure B1, the second laminar flow structure B2, and the third laminar flow structure B3 can be the same or different. When they are the same, the manufacturing process can be simplified. For example, the first laminar flow structure B1, the second laminar flow structure B2, and the third laminar flow structure B3 are all porous plates.

[0082] In this embodiment of the disclosure, the specific constructions of the first pre-laminar structure A1, the second pre-laminar structure A2, and the third pre-laminar structure A3 can be the same or different. When they are the same, the manufacturing process can be simplified.

[0083] Figure 12 This is a schematic diagram of the pre-laminar flow structure according to an embodiment of the present disclosure. For example, as... Figure 12 As shown, the pre-laminar flow structure (e.g., any one of the first pre-laminar flow structure A1, the second pre-laminar flow structure A2, and the third pre-laminar flow structure A3) of this disclosure includes rigid members A01, such as multiple rigid members A01 arranged along the x-direction. Each rigid member A01 has a U-shaped cross-section, and its sidewalls and bottom are provided with air outlets (i.e., shown by black dots in the figure), through which sterile air flows out. The bottom of the U-shape faces the laminar flow structure and has a planar shape. Through the above arrangement, the diffusion range or area of ​​sterile air towards the laminar flow structure can be increased.

[0084] Figure 13 This is a schematic diagram of a pre-laminar flow structure according to another embodiment of the present disclosure. Figure 13 As shown, the pre-laminar flow structure of this embodiment includes rigid members A02, such as multiple rigid members A02 arranged along the x-direction. Each rigid member A02 has a U-shaped cross-section, and its sidewalls and bottom are provided with air outlets (i.e., shown by black dots in the figure), through which sterile air flows out. The bottom of the U-shape faces the laminar flow structure and has a sloping or arc-shaped shape. Figure 13(Only the case of a sloping shape is shown) to form a wedge-shaped structure at the bottom. By forming a wedge-shaped structure at the bottom, after the cleaning liquid cleans the pre-laminar structure, the cleaning liquid can flow towards the center along the wedge-shaped bottom of the rigid member by gravity, which facilitates the self-drainage of the cleaned wastewater. For example, the bottom width W of the U-shape gradually decreases along the y-direction towards the laminar structure (e.g., vertically downward), which further facilitates the guidance and self-drainage of the waste liquid.

[0085] In the above embodiments, the first cleaning pipe 104 and the second cleaning pipe 204 are generally cylindrical. It is understood that in other embodiments, the first cleaning pipe 104 and the second cleaning pipe 204 may also be other forms of tubular components, such as square pipes.

[0086] Figure 14 This is a partial structural diagram of a filling device according to another embodiment of the present disclosure. Figure 1 . Figure 15 This is a partial structural diagram of a filling device according to another embodiment of the present disclosure. Figure 2 . Figure 16 This is a partial structural diagram of a filling device according to another embodiment of the present disclosure. Figure 3 . Figure 17 This is a partial structural diagram of a filling device according to another embodiment of the present disclosure. Figure 4 .

[0087] and Figures 1 to 13 Compared to the filling equipment shown, Figures 14 to 17 The filling equipment shown includes a third cleaning component 302 and a fourth cleaning component 402, which have the same construction but differ from the construction of the first cleaning component 102 and the second cleaning component 202. For example, both the third cleaning line 304 and the fourth cleaning line 404 are generally square tubular.

[0088] refer to Figure 14 and Figure 15 The first isolation wall 100 is provided with a first opening area OA1 to accommodate the third cleaning component 302. The third cleaning component 302 includes a third cleaning conduit 304 located in the first opening area OA1, and the third cleaning conduit 304 is configured to rotate about its own axis. The third cleaning conduit 304 includes a third main pipe 3041 and a third nozzle 3042 disposed on the third main pipe 3041. The third main pipe 3041 is configured to deliver cleaning liquid, and the third nozzle 3042 is configured to spray the delivered liquid. By rotating the third cleaning component 302, automatic cleaning of the first working area 10 and the second working area 20 can also be achieved.

[0089] For example, such as Figure 15As shown, the third cleaning conduit 304 is generally square-tube shaped. To facilitate the rotation of the third cleaning conduit 304, the distance between its two opposite sides 304a and 304b is less than the width of the first opening region OA1. Furthermore, when the third cleaning conduit 304 rotates, its sides 304a and 304b rotate along a rotation trajectory, which is the circumcircle of the square cross-section. The outlet edge of the third nozzle 3042 is positioned within this rotation trajectory, which provides the following advantages: 1) This further prevents damage to the third nozzle 3042 during rotation. 2) It simplifies the structure of the isolation wall. 3) When the third nozzle 3042 is, for example, in... Figure 15 When the positions shown are such that the distance between the first wall portion 100a and the third cleaning component 302 is small, the distance between the second wall portion 100b and the third cleaning component 302 is also small, which is conducive to the distribution of sterile air in the sterile room and at the same time better separates the first working area 10 and the second working area 20.

[0090] For example, such as Figure 14 As shown, the third main tube 3041 may be provided with a third recess CP3, and the third nozzle 3042 is disposed in the third recess CP3. The third nozzle 3042 is disposed in the third recess CP3 for processing considerations. This allows for better thinning of the square tube, ensuring that the weld can be fully penetrated during welding.

[0091] For example, refer to Figure 16 and Figure 17 The second isolation wall 200 is provided with a second opening area OA2 to accommodate the fourth cleaning component 402. The fourth cleaning component 402 includes a fourth cleaning conduit 404 located in the second opening area OA2, and the fourth cleaning conduit 404 is configured to rotate about its own axis. The fourth cleaning conduit 404 includes a fourth main pipe 4041 and a fourth nozzle 4042 disposed on the fourth main pipe 4041. The fourth main pipe 4041 is configured to deliver cleaning liquid, and the fourth nozzle 4042 is configured to spray the delivered liquid. By rotating the fourth cleaning component 402, automatic cleaning of the second working area 20 and the third working area 30 can also be achieved.

[0092] For example, such as Figure 17As shown, the fourth cleaning conduit 404 is generally square-shaped. To facilitate the rotation of the fourth cleaning conduit 404, the distance between its two opposite sides 404a and 404b is less than the width of the second opening region OA2. Furthermore, when the fourth cleaning conduit 404 rotates, its sides 404a and 404b rotate along a rotation trajectory that is the circumcircle of the square cross-section. The outlet edge of the fourth nozzle 4042 is positioned within this rotation trajectory, which provides the following advantages: 1) This further prevents damage to the fourth nozzle 4042 during rotation. 2) It simplifies the structure of the isolation wall. 3) When the fourth nozzle 4042 is, for example, in... Figure 17 When the positions shown are such that the distance between the third wall portion 200a and the fourth cleaning component 402 is small, the distance between the fourth wall portion 200b and the fourth cleaning component 402 is also small, which is conducive to the distribution of sterile air in the sterile room and at the same time better separates the second work area 20 and the third work area 30.

[0093] For example, such as Figure 16 As shown, the fourth main pipe 4041 is provided with a fourth recess CP4, and the fourth nozzle 4042 is disposed in the fourth recess CP4. The fourth nozzle 4042 is disposed in the fourth recess CP4 for processing considerations. This allows for better thinning of the square tube, ensuring that the weld can be fully penetrated during welding.

[0094] According to embodiments of this disclosure, a cleaning method for the filling equipment employing the foregoing embodiments is also provided. The cleaning method includes:

[0095] Step S100: Rotate at least one cleaning component to clean at least one of the at least two work areas.

[0096] In the cleaning method of the filling equipment provided in the above-described embodiments of the present disclosure, by setting an opening area on the isolation wall for accommodating the cleaning component and rotating the cleaning component located in the opening area, automatic cleaning of at least one of the at least two working areas can be achieved, which not only saves manpower and resources, but also makes the cleaning process simpler, more efficient and controllable.

[0097] Figure 18 This is a schematic flowchart of a cleaning method for a filling device provided in an embodiment of this disclosure. For example, in conjunction with... Figures 1 to 5 and Figure 18 At least one cleaning component includes a first cleaning component 102, and at least two working areas include a first working area 10 and a second working area 20. Step S100 includes:

[0098] S101: Rotate the first cleaning component 102 to clean at least one of the first working area 10 and the second working area 20.

[0099] In this embodiment, when the first cleaning component 102 rotates, it can automatically clean the first working area 10 and the second working area 20 respectively, without having to disassemble the parts to be cleaned in the first working area 10 and the second working area 20. This not only saves manpower and material costs, but also makes the cleaning process simpler, more efficient and controllable.

[0100] For example, refer to Figures 1 to 3 , Figures 8 to 9 and Figure 18 At least one cleaning component further includes a second cleaning component 202, and at least two work areas include a third work area 30. Step S100 above further includes:

[0101] S102: Rotate the second cleaning component 202 to clean at least one of the second working area 20 and the third working area 30.

[0102] In this embodiment, when the second cleaning component 202 rotates, it can automatically clean the second working area 20 and the third working area 30 respectively, without having to disassemble the parts to be cleaned in the second working area 20 and the third working area 30. This not only saves manpower and material costs, but also makes the cleaning process simpler, more efficient and controllable.

[0103] For example, refer to Figure 8 , Figure 9 and Figure 18 The third work area 30 includes a first sub-work area 30a and a second sub-work area 30b. Step S100 further includes:

[0104] S103: Rotate the second cleaning component 202 to clean at least one of the first sub-work area 30a and the second sub-work area 30b.

[0105] In this embodiment, when the second cleaning component 202 rotates, it can further realize the automatic cleaning of the first sub-working area 30a and the second sub-working area 30b respectively, without having to disassemble the parts to be cleaned in the first sub-working area 30a and the second sub-working area 30b. This not only saves manpower and material costs, but also makes the cleaning process simpler, more efficient and controllable.

[0106] In the filling equipment and filling method provided in the above-described embodiments, by providing an opening area for accommodating cleaning components on the isolation wall of the sterile chamber, automatic cleaning of at least one of the at least two working areas in the sterile chamber can be achieved. This not only saves manpower and resources but also makes the cleaning process simpler, more efficient, and more controllable. Compared to manually disassembling and cleaning detachable parts in the sterile chamber, it shortens cleaning time, improves cleaning efficiency, and makes the cleaning process and effect more controllable.

[0107] The following points should be noted in this article:

[0108] (1) The accompanying drawings of the embodiments of this disclosure only involve the structures involved in the embodiments of this disclosure. Other structures can be referred to the general design.

[0109] (2) Where there is no conflict, the embodiments of this disclosure and the features in the embodiments can be combined with each other to obtain new embodiments.
