[0045] In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments of the present disclosure. Based on the described embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without any creative effort fall within the scope of protection of the present disclosure.

Terms such as “upper,” “lower,” “left,” and “right” are used only to indicate relative positional relationships, and these relative positional relationships may change accordingly when the absolute position of the described object changes.

[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 3 This is a schematic diagram of the structure of the filling equipment according to an embodiment of the present disclosure. Figures 1 to 3 . 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 4Structure schematic of filling equipment of embodiments of the present disclosure Figure 1 .

[0052] For example, as shown in Figure 3 , the filling equipment comprises a sterile chamber 1, the sterile chamber 1 comprises at least one partition wall, the at least one partition wall is arranged to separate the sterile chamber 1 into at least two work areas along a first direction (for example, the x direction shown in the figure). For example, the at least one partition wall comprises a first partition wall 100, the first partition wall 100 is arranged to separate the sterile chamber 1 into a first work area 10 and a second work area 20 along the x direction, and the at least two work areas comprise the first work area 10 and the second work area 20. For example, the at least two work areas can comprise the second work area 20 and a third work area 30, and the at least one partition wall can further comprise a second partition wall 200, the second partition wall 200 is arranged to separate the sterile chamber 1 into the second work area 20 and the third work area 30 along the x direction. The first work area 10, the second work area 20 and the third work area 30 are arranged in sequence along the x direction, and the three work areas have different functions from each other. In embodiments of the present disclosure, the "at least one partition wall" can refer to the first partition wall 100 located between the first work area 10 and the second work area 20, can refer to the second partition wall 200 located between the second work area 20 and the third work area 30, or can refer to the first partition wall 100 and the second partition wall 200, and the present disclosure does not limit this. The "at least two work areas" includes two, three or more work areas, when including two work areas, it can include the first work area 10 and the second work area 20, or it can include the second work area 20 and the third work area 30, and the present disclosure does not limit this.

[0053] For example, the filling equipment can further comprise a conveying device (not shown), the conveying device moves along a conveying direction (for example, the x direction shown in Figure 4 ). A plurality of rows of containing units C (also referred to as sleeve grids) are arranged on the conveying device, each containing unit C contains a packaging container P (see Figure 5). When the conveying device moves along the x direction, the containing unit C also moves, and the packaging container P arranged in the containing unit C sequentially passes through three different working areas to be processed respectively. For example, the first working area 10 is a pre-processing area, and the pre-processing area is provided with a pre-processing device configured to perform a pre-processing operation on the packaging container P, including at least one of preheating, sterilization, and drying. In some embodiments, at least one of a preheating gas, a drying gas, and a sterilization gas is introduced into the packaging container P through the top opening of the packaging container P. For example, the second working area 20 is a filling area, and the filling area is provided with a filling device configured to perform a filling operation on the packaging container P. In some embodiments, the filling device fills the liquid food into the interior of the packaging container P through the top opening of the packaging container P. The third working area 30 is a sealing area. The sealing area is provided 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 further comprises a cleaning device, the cleaning device comprising at least one cleaning assembly arranged to be rotatable to clean at least one of the at least two working areas; wherein the partition wall has an opening region penetrating through the partition wall, the opening region being arranged to accommodate the cleaning assembly.

[0055] In the embodiments of the present disclosure, the "at least one cleaning assembly" can refer to the first cleaning assembly 102, the second cleaning assembly 202 (see the specific description of the first cleaning assembly 102 and the second cleaning assembly 202 below), or the first cleaning assembly 102 and the second cleaning assembly 202. The first cleaning assembly 102 will be described in detail below.

[0056] Figure 2 Partial structure diagram of the filling device of the embodiments of the present disclosure Figure 5 As shown in FIG. 1, the first working area 10 and the second working area 20 are arranged in the sterile room 1, and the first working area 10 and the second working area 20 are separated by the first partition wall 100. Figure 4 and Figure 5 As shown in FIG. 1, the first working area 10 and the second working area 20 are arranged in the sterile room 1, and the first working area 10 and the second working area 20 are separated by the first partition wall 100. In the embodiments of the present disclosure, the at least one cleaning assembly includes the first cleaning assembly 102 arranged to be rotatable to clean at least one of the first working area 10 and the second working area 20. For example, the first partition wall 100 has a first opening region OA1 penetrating through the first partition wall 100, and the first opening region OA1 is arranged to accommodate the first cleaning assembly 102. In the embodiments, by opening the first opening region OA1 on the first partition wall 100, the first working area 10 and the second working area 20 are communicated with each other at the first opening region OA1, so that when the first cleaning assembly 102 in the first opening region OA1 rotates, the automatic cleaning of the first working area 10 and the second working area 20 can be realized, and the components to be cleaned in the first working area 10 and the second working area 20 do not need to be disassembled, which not only saves manpower and material resources, but also makes the cleaning process simpler, more efficient and controllable.

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

[0058] In the embodiments of the present disclosure, by arranging the first cleaning assembly 102 on the first partition wall 100 between the first work area 10 and the second work area 20, the cleaning of the first work area 10 and the second work area 20 can be realized by only one first cleaning assembly 102. Compared with the above case, the total number of cleaning assemblies and the cleaning cost are reduced.

[0059] For example, the partition wall includes a first side and a second side arranged opposite to each other in the x direction, one of the at least two work areas is located on the first side, and the other work area is located on the second side; the cleaning assembly is arranged 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 A partial structure of a filling device according to an embodiment of the present disclosure Figure 3 As shown in Figure 4 , the first partition wall 100 includes a first partition wall first side S11 and a first partition wall second side S12 arranged opposite to each other in the x direction, the first work area 10 is located on the first partition wall first side S11, and the second work area 20 is located on the first partition wall second side S12. The first cleaning assembly 102 is arranged to clean the first work area 10 when rotated to the first partition wall first side S11 (i.e., the state shown in the figure, for example, the first work area 10 is a pretreatment area), and to clean the second work area 20 when rotated to the first partition wall second side S12 (for example, the second work area 20 is a filling area). In this way, by controlling the rotation direction or rotation angle of the first cleaning assembly 102, the automatic cleaning of the pretreatment area and the filling area can be realized respectively.

[0061] For example, the partition wall includes two wall portions arranged apart from each other in a second direction (for example, the y direction shown in the figure) to form an opening region, and the second direction intersects the first direction. In the embodiments of the present disclosure, the second direction and the first direction are perpendicular to each other as an example, and it can be understood that in other embodiments, the second direction and the first direction can not be perpendicular to each other, for example, an acute angle less than 90 degrees can be formed between the two directions, and the purpose of the present disclosure can also be achieved.

[0062] Reference Figure 4 and Figure 4The first partition wall 100 comprises a first wall part 100a and a second wall part 100b, which are arranged in the y direction to be spaced from each other to form a first opening area OA1. That is, the first opening area OA1 is located between the first wall part 100a and the second wall part 100b in the y direction. In order to facilitate the accommodation of the first cleaning assembly 102 and to enable the first cleaning assembly 102 to rotate freely, the width of the first opening area OA1 in the y direction is greater than the width of the first cleaning assembly 102 in the y direction. For example, the width of the first opening area OA1 in the y direction is greater than the width of the first cleaning assembly 102 in the y direction, and the difference therebetween can be less than any given positive number, which is more conducive to the isolation of the two working areas. In some embodiments, as shown in Figure 6 the first wall part 100a and the second wall part 100b are aligned in the same linear direction (for example, the y direction), so that the position of the first partition wall 100 in the existing equipment can not be changed, the division of the respective spaces of the filling area and the packaging area in the existing equipment is maintained, and the modification cost of the existing equipment is saved. For example, the cleaning assembly comprises a cleaning pipeline located in the opening area, and the cleaning pipeline is arranged to rotate about its own axis. Referring to Figure 1 and Figure 7 The first cleaning assembly 102 comprises a first cleaning pipeline 104 located in the first opening area OA1, and the first cleaning pipeline 104 has a first axis Z104 and is arranged to rotate about the first axis Z104. Since the first cleaning pipeline 104 is arranged between the pretreatment area and the filling area in the x direction and the first cleaning pipeline 104 can rotate about its own first axis Z104, the structure of the cleaning assembly itself can be further simplified while ensuring the automatic cleaning of the pretreatment area and the filling area.

[0063] For example, the cleaning pipeline comprises a main pipe and a nozzle arranged on the main pipe, the main pipe is arranged to convey a cleaning liquid, and the nozzle is arranged to spray the conveyed liquid; wherein the main pipe is provided with a recess, and the nozzle is arranged in the recess. Referring to Figure 2 The first cleaning pipeline 104 comprises a first main pipe 1041 and a first nozzle 1042 arranged on the first main pipe 1041, the first main pipe 1041 is arranged to convey a cleaning liquid, and the first nozzle 1042 is arranged to spray the conveyed liquid. The first main pipe 1041 is provided with a first recess CP1, and the first nozzle 1042 is arranged in the first recess CP1. By arranging the first nozzle 1042 in the first recess CP1, the following beneficial effects can be achieved: 1) the first nozzle 1042 can be prevented from colliding with the surrounding partition wall (for example, the first wall part 100a and the second wall part 100b) when the first main pipe 1041 rotates, thereby avoiding mechanical damage that the first cleaning assembly 102 can cause during cleaning. 2) The structure of the partition wall is simpler. 3) When the first nozzle 1042 is, for example, in the cleaning position, the first nozzle 1042 is arranged in the first recess CP1, so that the first nozzle 1042 is arranged to be flush with the first wall part 100a and the second wall part 100b, thereby avoiding the first nozzle 1042 from being damaged by the first wall part 100a and the second wall part 100b. Figure 6When the first wall portion 100a and the first cleaning assembly 102 (e.g. the first main pipe 1041) are in the shown position, the distance between the first wall portion 100a and the first cleaning assembly 102 (e.g. the first main pipe 1041) is small, and the distance between the second wall portion 100b and the first cleaning assembly 102 (e.g. the first main pipe 1041) is also small, thereby facilitating the distribution of sterile air in the sterile chamber, and better separating the first working area 10 and the second working area 20.

[0064] For example, the number of the nozzles is multiple, the main pipe comprises a first mounting end, a second mounting end and an intermediate segment between the first mounting end and the second mounting end; the nozzle closest to the first mounting end or the second mounting end is defined as an end nozzle, and the nozzle between the two end nozzles is defined as an intermediate nozzle; the end nozzle has a first included angle relative to the axial direction of the main pipe, and the intermediate nozzle has a second included angle relative to the axial direction of the main pipe; the first included angle and the second included angle are not equal. It can be understood that in other embodiments of the present disclosure, the first included angle and the second included angle are set to be equal according to actual needs.

[0065] Figure 7 Structure diagram of the first cleaning assembly of the embodiment of the present disclosure Figure 7 . Structure diagram of the first cleaning assembly of the embodiment of the present disclosure Figure 8 . As shown in Figure 3 . As shown in Figure 8 and Figure 9 The number of the first nozzles 1042 is multiple, the first main pipe 1041 comprises a first mounting end 1041a, a second mounting end 1041b and a first intermediate segment 1041c 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 a first end nozzle 1042a, and the first nozzle 1042 between the two first end nozzles 1042a is defined as a first intermediate nozzle 1042b. The first end nozzle 1042a has a first included angle a1 relative to the axial direction of the first main pipe 1041 (i.e. the rotation axis Z104 of the first cleaning pipeline 104), the first intermediate nozzle 1042b has a second included angle a2 relative to the axial direction of the first main pipe 1041, and the first included angle a1 and the second included angle a2 are not equal. In the present embodiment, the first main pipe 1041 can be fixedly installed in the sterile chamber 1 by means of the first mounting end 1041a and the second mounting end 1041b, thereby improving the stability of the first main pipe 1041 during rotation. By setting the first included angle a1 and the second included angle a2 to be unequal (for example, the first included angle a1 is greater than the second included angle a2), the first intermediate nozzle 1042b is closer to the rotation axis Z104 of the first cleaning pipeline 104, thereby facilitating the distribution of sterile air in the sterile chamber 1. Figure 4The second included angle a2 is greater than the first included angle a1, which is beneficial to improve the cleaning effect on the vertical partition wall of the sterile chamber 1 close to the first mounting end 1041a and the second mounting end 1041b (for example, the first main pipe 1041 is mounted to the vertical partition wall through the first mounting end 1041a and the second mounting end 1041b). In some embodiments, the second included angle a2 is a right angle, and the first included angle a1 is an acute angle.

[0066] For example, the number of the first intermediate nozzles 1042b is multiple, and the multiple first intermediate nozzles 1042b are arranged at equal intervals. In this way, the uniformity of the cleaning effect can be ensured. It can be understood that in the embodiments of the present disclosure, the multiple first intermediate nozzles 1042b can also be arranged at unequal intervals, and those skilled in the art can arrange the intervals and the number of the multiple first intermediate nozzles 1042b according to actual needs, and the embodiments of the present disclosure are not limited in this regard.

[0067] The second cleaning assembly 202 will be further described below.

[0068] Figure 9 A partial structure of the filling device of the embodiments of the present disclosure Figure 8 As shown in Figure 9 and Figure 9 For example, the second partition wall 200 has a second opening area OA2 penetrating through the second partition wall 200, and the second opening area OA2 is arranged to accommodate the second cleaning assembly 202. In the present embodiment, by opening the second opening area OA2 on the second partition wall 200, the second working area 20 and the third working area 30 are communicated with each other at the second opening area OA2, so that when the second cleaning assembly 202 in the second opening area OA2 rotates, the automatic cleaning of the second working area 20 and the third working area 30 can be realized, without the need to disassemble the to-be-cleaned components in the second working area 20 and the third working area 30, which not only saves manpower and material resources, but also makes the cleaning process simpler, more efficient and controllable.

[0069] In some cases, if the second cleaning assembly 202 is not arranged on the second partition wall 200 between the second working area 20 and the third working area 30 (for example, arranged inside the second working area 20 or the third working area 30), one or more cleaning assemblies need to be arranged in each working area, and these cleaning assemblies are responsible for the automatic cleaning of the working area where the cleaning assembly is located, but cannot clean other working areas, resulting in a large total number of cleaning assemblies, which is not conducive to controlling the cleaning effect and also increases the cleaning cost.

[0070] In the embodiments of the present disclosure, by arranging the second cleaning assembly 202 on the second partition wall 200 between the second working area 20 and the third working area 30, the cleaning of the second working area 20 and the third working area 30 can be realized by only one second cleaning assembly 202. Compared with the above case, the total number of cleaning assemblies and the cleaning cost are reduced.

[0071] Figure 3 Partial structure of the filling equipment of the embodiments of the present disclosure Figure 8 As shown in Figure 8 , the second partition wall 200 includes a second partition wall first side S21 and a second partition wall second side S22 arranged opposite to each other in the x direction, the second working area 20 is located on the second partition wall first side S21, and the third working area 30 is located on the second partition wall second side S22. The second cleaning assembly 202 is arranged to clean the second working area 20 (for example, the filling area in the state shown in the figure) when rotated to the second partition wall first side S21, and to clean the third working area 30 (for example, the packaging area) when rotated to the second partition wall second side S22. In this way, by controlling the rotation direction or rotation angle of the second cleaning assembly 202, automatic cleaning of the filling area and the packaging area respectively can be realized.

[0072] Referring to Figure 10 and Figure 1 , the second partition wall 200 includes a third wall portion 200a and a fourth wall portion 200b, and the third wall portion 200a and the fourth wall portion 200b are arranged to be spaced from each other in the y direction to form a second opening area OA2. That is, the second opening area OA2 is located between the third wall portion 200a and the fourth wall portion 200b in the y direction. In order to accommodate the second cleaning assembly 202 and to enable the second cleaning assembly 202 to rotate freely, the width of the second opening area OA2 in the y direction is greater than the width of the second cleaning assembly 202 in the y direction. In some embodiments, as shown in Figure 11 , the third wall portion 200a and the fourth wall portion 200b are aligned along the same linear direction (for example, the y direction), so that the position of the first partition wall 100 in the existing equipment can not be changed, the division of the respective spaces of the filling area and the packaging area in the existing equipment can be maintained, and the modification cost of the existing equipment can be saved.

[0073] For example, referring to Figure 2The second cleaning assembly 202 comprises a second cleaning pipe 204 located in the second opening area OA2, the second cleaning pipe 204 has a second axis Z204 and is arranged to rotate around the second axis Z204. Since the second cleaning pipe 204 is arranged between the filling area and the packaging area along the x direction and the second cleaning pipe 204 can rotate around the second axis Z204 thereof, the structure of the cleaning assembly can be further simplified under the premise of ensuring automatic cleaning of the filling area and the packaging area.

[0074] For example, with reference to Figure 10 The second cleaning pipe 204 comprises a second main pipe 2041 arranged to deliver cleaning liquid and a second nozzle 2042 arranged on the second main pipe 2041 and arranged to spray the delivered liquid. The second main pipe 2041 is provided with a second recess CP2, and the second nozzle 2042 is arranged in the second recess CP2. By arranging the second nozzle 2042 in the second recess CP2, the following beneficial effects can be achieved: 1) the second nozzle 2042 can be prevented from colliding with the surrounding partition walls (for example, the third wall portion 200a and the fourth wall portion 200b) when the second main pipe 2041 rotates, thereby avoiding possible mechanical damage to the second cleaning assembly 202 during cleaning. 2) The structure of the partition wall is simpler. 3) When the second nozzle 2042 is in the position shown in FIG. 6A, for example, the distance between the third wall portion 200a and the second cleaning assembly 202 (for example, the second main pipe 2041) is small, and the distance between the fourth wall portion 200b and the second cleaning assembly 202 (for example, the second main pipe 2041) is also small, thereby facilitating the distribution of sterile air in the sterile room and better separating the second working area 20 and the third working area 30. Figure 11

[0075] In the embodiments of the present disclosure, the specific structures of the first cleaning assembly 102 and the second cleaning assembly 202 can be the same or different. When the structures of the first cleaning assembly 102 and the second cleaning assembly 202 are the same, the manufacturing process can be simplified, and the cleaning process or the cleaning process can be controlled. The embodiments of the present disclosure are described by taking the case that the structures of the first cleaning assembly 102 and the second cleaning assembly 202 are the same.

[0076] Figure 7 The structure of the second cleaning assembly of the embodiments of the present disclosure is shown in FIG. 6A. Figure 1 .The structure of the second cleaning assembly of the embodiments of the present disclosure is shown in FIG. 6A. Figure 2 The structure of the second cleaning assembly of the embodiments of the present disclosure is shown in FIG. 6A. Figure 1 . The structure of the second cleaning assembly of the embodiments of the present disclosure is shown in FIG. 6A. Figure 4 and Figure 8As shown, the number of the second nozzles 2042 is multiple, and the second main pipe 2041 includes a third mounting end 2041a, a fourth mounting end 2041b, and a second intermediate segment 2041c 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 a second end nozzle 1042a, and the second nozzle 2042 between the two second end nozzles 1042a is defined as a second intermediate nozzle 1042b. The second end nozzle 1042a has a third included angle a3 with respect to the axial direction of the second main pipe 2041 (for example, the rotation axis of the second cleaning pipeline 204), and the second intermediate nozzle 1042b has a fourth included angle a4 with respect to the axial direction of the second main pipe 2041. The third included angle a3 and the fourth included angle a4 are not equal. In this embodiment, the third mounting end 2041a and the fourth mounting end 2041b can be used to fix the second main pipe 2041 in the sterile room 1, thereby improving the stability of the second main pipe 2041 during rotation. By setting the third included angle a3 and the fourth included angle a4 to be unequal (for example, the fourth included angle a4 is greater than the third included angle a3 as shown in FIG. 4B), the cleaning effect of the vertical partition wall of the sterile room 1 close to the third mounting end 2041a and the fourth mounting end 2041b can be improved (for example, the second main pipe 2041 can be mounted on the vertical partition wall through the third mounting end 2041a and the fourth mounting end 2041b). In some embodiments, the fourth included angle a4 is a right angle, and the third included angle a3 is an acute angle. Figure 2

[0077] For example, the number of the second intermediate nozzles 1042b is multiple, and the multiple second intermediate nozzles 1042b are arranged at equal intervals. In this way, the uniformity of the cleaning effect can be ensured. It can be understood that in the embodiments of the present disclosure, the multiple second intermediate nozzles 1042b can also be arranged at unequal intervals. Those skilled in the art can set the interval and number of the multiple second intermediate nozzles 1042b according to actual needs, and the embodiments of the present disclosure do not limit this.

[0078] For example, the filling device further includes at least one pre-laminar flow structure and at least one laminar flow structure arranged at intervals in the y direction. The pre-laminar flow structure is configured to guide the sterile air in the sterile room 1. In combination with Figure 8 and Figure 9 , the at least one pre-laminar flow structure includes, for example, a first pre-laminar flow structure A1 located in the first working area 10 and a second pre-laminar flow structure A2 located in the second working area 20. The laminar flow structure is configured to guide the sterile air again to increase the diffusion or delivery range of the sterile air. As shown in Figure 9 , the 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. As shown in Figure 9 ​As 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 9 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 12 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 12 and Figure 13 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 13As 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 13 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 14 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 1 This is a schematic diagram of the pre-laminar flow structure according to an embodiment of the present disclosure. For example, as... Figure 15 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 2 This is a schematic diagram of a pre-laminar flow structure according to another embodiment of the present disclosure. Figure 16 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 3The wedge-shaped structure at the bottom is formed. By forming the wedge-shaped structure at the bottom, after the pre-laminar flow structure is cleaned by the cleaning liquid, the cleaning liquid can flow to the center along the wedge-shaped bottom of the rigid piece according to gravity, thereby facilitating the self-discharge of the waste water after cleaning. For example, the bottom width W of the U-shaped gradually decreases in the y direction towards the laminar flow structure (for example, the vertical downward direction), so that the flow and self-discharge of the waste liquid are more facilitated.

[0085] In the above embodiments, the first cleaning pipeline 104 and the second cleaning pipeline 204 are generally circular tubes. It can be understood that in other embodiments, the first cleaning pipeline 104 and the second cleaning pipeline 204 can also be other forms of tubular pieces, such as square tubes.

[0087] Compared with the filling device shown in Figure 14 , the filling device shown in Figure 16 includes a third cleaning assembly 302 and a fourth cleaning assembly 402, the third cleaning assembly 302 and the fourth cleaning assembly 402 have the same structure, but different from the structure of the first cleaning assembly 102 and the second cleaning assembly 202. For example, the third cleaning pipeline 304 and the fourth cleaning pipeline 404 are generally square tubes.

[0088] Referring to Figure 17 and Figure 17 , the first partition wall 100 is provided with a first opening area OA1 accommodating the third cleaning assembly 302, the third cleaning assembly 302 includes a third cleaning pipeline 304 located in the first opening area OA1, and the third cleaning pipeline 304 is arranged to rotate around its own axis. The third cleaning pipeline 304 includes a third main pipe 3041 arranged to transport cleaning liquid and a third nozzle 3042 arranged to spray the transported liquid, and the third main pipe 3041 is arranged to transport cleaning liquid. By rotating the third cleaning assembly 302, automatic cleaning of the first working area 10 and the second working area 20 can also be achieved.

[0089] For example, as Figure 17As shown, the third cleaning pipe 304 is generally square tubular. In order to facilitate the rotation of the third cleaning pipe 304, the distance between two opposite sides 304a, 304b of the third cleaning pipe 304 is less than the width of the first opening area OA1. Further, when the third cleaning pipe 304 rotates, its sides 304a, 304b rotate along a rotation locus which is the circumscribed circle of the square cross section. The outlet edge of the third nozzle 3042 is arranged to be located within the rotation locus, which can bring the following beneficial effects: 1) this can further avoid damage to the third nozzle 3042 during rotation. 2) the structure of the partition wall is simpler. 3) when the third nozzle 3042 is, for example, in the Figure 16 As shown, the distance between the first wall portion 100a and the third cleaning assembly 302 can be small, and the distance between the second wall portion 100b and the third cleaning assembly 302 can also be small when the third nozzle 3042 is, for example, in the

[0090] For example, as shown in Figure 18 The third main pipe 3041 can be provided with a third recess CP3, and the third nozzle 3042 is arranged in the third recess CP3. Arranging the third nozzle 3042 in the third recess CP3 is for consideration of the machining process, which can better thin the square tube to ensure that the weld can be penetrated when welding.

[0091] For example, referring to Figures 1 to 5 and Figure 18 The second partition wall 200 is provided with a second opening area OA2 accommodating a fourth cleaning assembly 402, and the fourth cleaning assembly 402 includes a fourth cleaning pipe 404 arranged in the second opening area OA2, and the fourth cleaning pipe 404 is arranged to rotate around its own axis. The fourth cleaning pipe 404 includes a fourth main pipe 4041 arranged to transport cleaning liquid, and a fourth nozzle 4042 arranged to spray the transported liquid. By rotating the fourth cleaning assembly 402, automatic cleaning of the second working area 20 and the third working area 30 can also be achieved.

[0092] For example, as shown in Figures 1 to 3As 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... Figures 8 to 9 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 18 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 8 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... Figure 9 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 the embodiment, when the first cleaning assembly 102 rotates, automatic cleaning of the first working area 10 and the second working area 20 can be achieved without disassembling the to-be-cleaned components in the first working area 10 and the second working area 20, which not only saves manpower and material resources, but also makes the cleaning process simpler, more efficient and controllable.

[0100] For example, referring to ​ , ​ and ​ , the at least one cleaning assembly further includes a second cleaning assembly 202, and the at least two working areas include a third working area 30. The step S100 further includes:

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

[0102] In the embodiment, when the second cleaning assembly 202 rotates, automatic cleaning of the second working area 20 and the third working area 30 can be achieved without disassembling the to-be-cleaned components in the second working area 20 and the third working area 30, which not only saves manpower and material resources, but also makes the cleaning process simpler, more efficient and controllable.

[0103] For example, referring to ​ , ​ and ​ , the third working area 30 includes a first sub-working area 30a and a second sub-working area 30b. The step S100 further includes:

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

[0105] In the embodiment, when the second cleaning assembly 202 rotates, automatic cleaning of the first sub-working area 30a and the second sub-working area 30b can be further achieved without disassembling the to-be-cleaned components in the first sub-working area 30a and the second sub-working area 30b, which not only saves manpower and material resources, but also makes the cleaning process simpler, more efficient and controllable.

[0106] In the filling device and the filling method provided by the embodiments of the present disclosure, by setting an opening area for accommodating a cleaning assembly on the partition wall in the sterile chamber, automatic cleaning of at least one of the at least two working areas in the sterile chamber can be achieved, which not only saves manpower and material resources, but also makes the cleaning process simpler, more efficient and controllable. Compared with manually disassembling and cleaning the detachable components in the sterile chamber, the cleaning time is shortened, the cleaning efficiency is improved, and the cleaning process and effect become more controllable.

[0107] In this document, the following points need to be noted:

[0108] (1) The drawings of the embodiments of the present disclosure only relate to the structures involved in the embodiments of the present disclosure, and other structures can be referred to the general design.

[0109] (2) In the case of no conflict, the embodiments of the present disclosure and the features in the embodiments can be combined to obtain new embodiments.
