The cleaning module includes a base with an internal cavity for containing liquid or gas, and a medium inlet communicating with the cavity. A cleaning channel penetrating the base allows bottles to pass through. The inner wall of the cleaning channel has spray holes communicating with the cavity, which spray liquid or gas from the cavity into the cleaning channel to clean the bottles located within it. Integrating the cavity and cleaning channel into the base reduces the space occupied by the cleaning module.

Description

Technical Field

[0001] This application relates to the field of bottle cleaning device technology, and in particular to a cleaning module and a bottle washing and drying system. Background Technology

[0002] In the production process of bottled medical injections, oral liquids, and other bottled products, residual medication or oral liquid contaminants often adhere to the outer wall of the bottle after the filling and sealing processes. If not removed in time, these contaminants will directly affect the processing quality of subsequent printing and labeling processes, leading to problems such as unclear labeling and reduced adhesion. Therefore, effective cleaning and drying of the outer wall of the bottle must be carried out between the filling and sealing processes and the printing and labeling processes.

[0003] Currently common cleaning devices typically have several independent water nozzles and air nozzles installed along the bottle conveyor line, with each nozzle connected by corresponding pipelines. When the bottle is conveyed to the cleaning area, the water nozzles first spray and rinse the bottle, followed by the air nozzles drying it. However, the water nozzles, air nozzles, and their associated pipelines occupy a large amount of space, which is not conducive to a compact production line layout. Secondly, the nozzles are usually spaced apart above the conveyor line, resulting in the sprayed water mist and airflow not being fully applied to the bottle wall. Most of the water mist and airflow escapes into the space above the conveyor line, causing low utilization of water and compressed air, increasing water consumption, and also increasing the energy consumption required by the air nozzles. Summary of the Invention

[0005] The first aspect of this application provides a cleanup module, including: The substrate has an internal cavity for containing liquid or gas, and the substrate has a medium inlet communicating with the cavity; The substrate is provided with a cleaning channel that penetrates the substrate, and the cleaning channel allows the bottle to be cleaned to pass through; The inner wall of the cleaning channel is provided with a spray hole that communicates with the receiving cavity. The spray hole is used to spray liquid or gas in the receiving cavity into the cleaning channel to clean the bottle to be cleaned located in the cleaning channel.

[0006] Optionally, a cleaning groove is formed by a recess on one side of the substrate, the cleaning groove extends along a first direction to penetrate the substrate, the groove wall defines the cleaning channel, and the spray hole is disposed on the groove wall of the cleaning groove.

[0007] Optionally, the cleaning tank includes a plurality of sub-tanks that penetrate the substrate along the first direction, the plurality of sub-tanks being spaced apart along the second direction, and each sub-tank having a spray hole on its tank wall, the second direction being perpendicular to the first direction.

[0008] Optionally, the two opposite sidewalls of the cleaning groove along the second direction are both wavy curved surfaces, and the two wavy curved surfaces are symmetrically arranged to jointly form a wavy channel extending along the first direction. The second direction is perpendicular to the first direction.

[0009] Optionally, the spray hole is located on the bottom of the cleaning tank.

[0010] Optionally, the injection hole extends along the extension direction of the cleaning channel.

[0011] Optionally, the spray hole includes a plurality of sub-spray nozzles, which are spaced apart along the extension direction of the cleaning channel.

[0012] Optionally, the receiving cavity includes a first cavity and a second cavity that are isolated from each other, and the first cavity and the second cavity are arranged along the extension direction of the cleaning channel; The medium inlet includes a first opening and a second opening, the first opening being in communication with the first cavity and the second opening being in communication with the second cavity; The inner wall of the cleaning channel is provided with two spray holes arranged along the extension direction of the cleaning channel, and the two spray holes are respectively connected to the first cavity and the second cavity.

[0013] Optionally, a guide plate is provided inside the receiving cavity. The guide plate is connected to the inner wall of the receiving cavity, and one end of the guide plate extends to the medium inlet and the other end extends to the injection hole to guide liquid or gas from the medium inlet to the injection hole.

[0014] A second aspect of this application provides a bottle washing and drying system, including a conveyor belt, a water supply unit, an air compression unit, and two cleaning modules as described in any of the preceding claims; The two substrates are arranged along the conveying direction of the conveyor belt, with the upstream substrate serving as a cleaning unit and the downstream substrate serving as a drying unit. The water supply unit is connected to the medium inlet of the cleaning unit to inject water into the receiving cavity of the cleaning unit; The air compression unit is connected to the medium inlet of the drying unit to inject compressed air into the receiving cavity of the drying unit; The conveyor belt is used to transport the bottles to be cleaned through the cleaning channels of the cleaning unit and the drying unit in sequence.

[0015] The technical solution provided in this application has the following advantages compared with the prior art: This application provides a cleaning module, including a substrate with a receiving cavity inside and a cleaning channel on the substrate. The inner wall of the cleaning channel has spray holes communicating with the receiving cavity. The substrate integrates the receiving cavity and the cleaning channel. By introducing liquid or gas into the receiving cavity, the bottles to be cleaned within the cleaning channel can be cleaned and dried. This integrates the nozzles and piping of traditional cleaning devices into the cleaning module, reducing the space occupied by the module. After each bottle enters the cleaning channel, the inner wall of the channel surrounds the bottle, creating a working space that restricts the escape of liquid or gas. The spray holes are located close to the bottle on the inner wall of the cleaning channel. During spraying, the water mist ejected from the spray holes is confined within this working space, allowing the water mist to concentrate on the surface of the bottle. This reduces losses caused by liquid escape in traditional open spraying, thus significantly reducing water consumption while ensuring cleaning effectiveness. In the drying mode, this workspace effectively guides and converges airflow, allowing the compressed air ejected from the spray nozzles to act concentratedly and at high speed on the surface of the bottles to be cleaned, quickly drying residual droplets and reducing the requirements for air source pressure, thereby reducing the energy consumption for drying the bottles. Multiple bottles can pass through the cleaning channel sequentially and continuously under the drive of a conveyor belt, allowing each bottle to be sprayed or dried, enabling the cleaning module to meet the cleaning needs of large-volume bottled products.

Detailed Implementation

[0020] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0022] After the filling and sealing process of bottled medical injections, oral liquids, and other bottled products is completed, residual medication or oral liquid contaminants often adhere to the outer wall of the bottle. These need to be removed promptly to avoid affecting subsequent printing and labeling processes. Typically, the bottled products are moved to a cleaning area equipped with nozzles and tubing. Water is sprayed onto the bottled products using a water nozzle connected to the rinsing tubing to remove any residual liquid. Then, air is blown onto the bottled products using an air nozzle connected to the ductwork to evaporate the liquid on the outer wall.

[0023] A certain number of independent water nozzles and air nozzles are installed along the conveyor line for bottled products. These nozzles are connected by corresponding pipelines, creating cleaning zones along the conveyor line. Bottled products entering these zones are sprayed with water mist from the water nozzles and dried by the airflow from the air nozzles. However, the water and air nozzles and their corresponding pipelines require fixed installations along the conveyor line, resulting in a significant space occupation for these structures. To prevent the water and air nozzles from interfering with the movement of the bottled products, a large distance is maintained between the nozzles and the conveyor line. Furthermore, the nozzles spray and dry the bottled products in the open space above the conveyor line, requiring the water mist from the water nozzles to cover a large area. Much of the water mist dissipates before fully contacting the bottled products, and a large portion of the airflow from the air nozzles also dissipates in the open space, leading to high water consumption for the water nozzles and high energy consumption for the air nozzles.

[0024] To solve the above technical problems, refer to Figures 1 to 9 As shown, the first aspect of this application provides a cleaning module, including a base 1. The base 1 has a receiving cavity 11 for containing liquid or gas inside, and a medium inlet 12 communicating with the receiving cavity 11 on the base 1. The base 1 has a cleaning channel penetrating the base 1, and the cleaning channel allows the bottle to be cleaned to pass through. The inner wall of the cleaning channel has a spray hole 21 communicating with the receiving cavity 11. The spray hole 21 is used to spray the liquid or gas in the receiving cavity 11 into the cleaning channel to clean the bottle to be cleaned located in the cleaning channel.

[0025] The substrate 1 integrates a receiving cavity 11 and a cleaning channel. By introducing liquid or gas into the receiving cavity 11, the bottles to be cleaned within the cleaning channel can be cleaned and dried. This integrates the nozzles and piping of traditional cleaning devices into the cleaning module, reducing the space occupied by the cleaning module. After each bottle enters the cleaning channel, the inner wall of the channel surrounds the bottle, creating a working space that restricts the escape of liquid or gas. The spray nozzle 21 is located close to the bottle on the inner wall of the cleaning channel. During spraying, the water mist ejected from the spray nozzle 21 is confined within this working space, allowing the water mist to concentrate on the surface of the bottle, reducing losses caused by liquid escape in traditional open spraying. This significantly reduces water consumption while maintaining cleaning effectiveness. During drying, this working space effectively guides and converges airflow, allowing the compressed air ejected from the spray nozzle 21 to act concentratedly and at high speed on the surface of the bottle, quickly drying residual droplets and reducing the requirement for air source pressure, thereby reducing energy consumption for drying the bottles. Multiple bottles pass through the cleaning channel sequentially and continuously under the drive of the conveyor belt, allowing each bottle to be sprayed or dried, thus enabling the cleaning module to meet the cleaning needs of a large number of bottled products.

[0026] Traditional cleaning devices, when handling large quantities of bottled products, typically gather multiple bottles in the cleaning area of ​​the conveyor line. Because these bottles can obstruct each other, the spraying and drying time of the water and air nozzles needs to be extended to ensure effective cleaning and drying. Therefore, during cleaning and drying operations, multiple bottles must be stopped, impacting production line efficiency. In contrast, multiple bottles can be sequentially and continuously passed through the cleaning channel driven by a conveyor belt, allowing each bottle to be sprayed or dried individually. During this process, each bottle receives its own water or air jet from the spray nozzle 21, ensuring effective cleaning and drying and preventing mutual obstruction. Furthermore, the sequential passage of multiple bottles through the cleaning channel eliminates the time spent on bottle start-stop and positioning in traditional methods, significantly improving the efficiency of cleaning large quantities of bottled products.

[0027] Specifically, the substrate 1 can be a rectangular block structure with a hollow interior forming a receiving cavity 11. A channel can be drilled in the substrate 1 to serve as a cleaning channel. The cleaning channel can be straight or curved, as long as the two ends of the cleaning channel form openings on the surface of the substrate 1, allowing the bottle to be cleaned to enter the interior of the substrate 1 from one end of the cleaning channel and leave the substrate 1 from the other end of the cleaning channel.

[0028] In some embodiments, a cleaning groove 2 is formed by a recess on one side of the substrate 1. The cleaning groove 2 extends along a first direction to penetrate the substrate 1. The groove wall of the cleaning groove 2 defines a cleaning channel. A spray hole 21 is disposed on the groove wall of the cleaning groove 2.

[0029] This design allows the U-shaped cleaning trough 2 to be adapted to the conveyor belt transporting the bottles to be cleaned. The bottom and walls of the cleaning trough 2 surround the bottles in both the horizontal and vertical directions, forming a three-sided enclosure structure, which reduces the escape of liquid or gas sprayed from the spray holes 21. The straight cleaning trough 2 along the first direction is easy to process and facilitates the movement of the bottles to be cleaned, avoiding jamming when the bottles move in the cleaning channel.

[0030] Specifically, a cleaning groove 2 can be formed by recessing one side of the substrate 1. Openings are formed at both ends of the cleaning groove 2 on the side walls of the substrate 1 along the first direction, and the opening of the cleaning groove 2 is exposed on the surface of the substrate 1. The substrate 1 is installed on the top side of the conveyor belt, with the opening of the cleaning groove 2 facing the conveyor belt. When the bottle to be cleaned is placed on the conveyor belt and moves with it, the bottle can enter the cleaning groove 2 through the opening in the side wall of the substrate 1. The opening of the cleaning groove 2 ensures that the bottle remains connected to the conveyor belt, allowing the conveyor belt to drive the bottle through the cleaning groove 2.

[0031] A U-shaped cleaning groove 2 is formed by a recess on one side of the substrate 1, making the cleaning groove 2 compatible with the conveyor belt conveying method. When the bottle to be cleaned enters the cleaning groove 2, the groove wall guides and limits the bottle to be cleaned. After the liquid or gas enters the receiving cavity 11 through the medium inlet 12, it is sprayed into the groove through the spray holes 21 on the groove wall.

[0032] The size of the cleaning tank 2 is set according to the size of the bottle to be cleaned, so that the tank wall and bottom of the cleaning tank 2 surround the bottle to be cleaned. When gas or liquid enters the cleaning tank 2, it can form a water flow or air flow with a specific flow line towards the bottle to be cleaned, so that the gas or liquid can be concentrated on the bottle to be cleaned.

[0033] like Figure 1 and Figure 6 As shown, the first direction a can be selected as the width direction of the base 1, and the second direction b can be selected as the length direction of the base 1. Alternatively, the first direction a can be selected as the length direction of the base 1, and the second direction b can be selected as the width direction of the base 1.

[0034] In some embodiments, the cleaning tank 2 includes a plurality of sub-tanks 22 that penetrate the substrate 1 along a first direction. The plurality of sub-tanks 22 are spaced apart along a second direction. Each sub-tank 22 has a spray hole 21 on its tank wall. The second direction is perpendicular to the first direction.

[0035] This design, with multiple sub-tanks 22 arranged in parallel, enables the simultaneous cleaning of multiple bottles, improving the cleaning efficiency of the cleaning module and meeting the needs of large-scale production of bottled products. Each sub-tank 22 is independent of the others, and each sub-tank 22 is equipped with a spray hole 21 to ensure consistent cleaning results for each bottle.

[0036] Specifically, the sub-groove 22 is a U-shaped groove. Multiple sub-groove 22 can be formed by cutting the bottom side of the base 1. Alternatively, the base 1 can include a main body and multiple partitions. The multiple partitions are connected to one side of the main body. The multiple partitions are parallel to each other and spaced apart along the second direction. A sub-groove 22 is formed between two adjacent partitions.

[0037] Each sub-tank 22 has spray holes 21 on its wall, so that the liquid and gas in the receiving cavity 11 can be respectively input into the multiple sub-tanks 22 through the multiple spray holes 21; each sub-tank 22 can pass through the bottles to be cleaned, so that multiple bottles to be cleaned can be sprayed or dried simultaneously through multiple sub-tanks 22, and the multiple sub-tanks 22 form a cleaning matrix to clean multiple bottles to be cleaned at the same time, which increases the cleaning efficiency.

[0038] In traditional cleaning devices, anti-tipping devices are installed on the conveyor line to prevent bottles from being knocked over by water or airflow during the cleaning process, allowing only one bottle to enter the cleaning area at a time. To clean multiple bottles simultaneously, multiple nozzles and pipelines need to be installed side-by-side, resulting in a large footprint and high cost for traditional cleaning devices. The cleaning module provided in this application, however, has multiple side-by-side sub-tanks 22 on the base 1. Each sub-tank 22 can accommodate bottles for cleaning, and only requires openings in each sub-tank 22 to allow gas or liquid in the receiving cavity 11 to be sprayed through multiple nozzles 21 to clean or dry the corresponding bottles in the sub-tank 22. The cleaning module is small in size, simple to manufacture, and has a low cost, effectively reducing the footprint and cost of bottle production lines.

[0039] Reference Figure 3 , Figure 4 , Figure 8 and Figure 9 As shown, in some embodiments, the two sidewalls of the cleaning groove 2 opposite each other along the second direction are both wavy curved surfaces, and the two wavy curved surfaces are symmetrically arranged to jointly form a wavy channel extending along the first direction; the second direction is perpendicular to the first direction.

[0040] With this design, once the bottle to be cleaned enters the cleaning channel, the wavy surface provides a limiting effect in both the first and second directions, preventing the bottle from tipping over. The wavy channel also provides a slight rotational guide for the bottle, causing it to rotate slowly during movement, further ensuring uniform cleaning of all parts of the bottle's outer wall.

[0041] Specifically, the undulation pattern of the wave-shaped surface is as follows: with the axis of the cleaning groove 2 as the center, periodic waves are formed along the second direction, and both sidewalls of the cleaning groove 2 along the second direction are wave-shaped surfaces.

[0042] The wavy curved surface relative to the axis of the cleaning groove 2 can be divided into a raised portion and a recessed portion. The two wavy curved surfaces are symmetrically arranged, with the raised portion of one wavy curved surface facing the recessed portion of the other wavy curved surface along a second direction. The distance between the two wavy curved surfaces in the opposite direction is equal everywhere to facilitate the movement of the bottle to be cleaned within the cleaning groove 2. The spray hole 21 can be set at the bottom of the cleaning groove 2 or on the wavy curved surface.

[0043] After the bottle to be cleaned enters the wavy channel, the bottle to be cleaned is limited by two wavy curved surfaces on both sides along the second direction. The bottle to be cleaned and the raised parts of the wavy curved surfaces partially overlap on both sides along the first direction, so that the wavy curved surfaces also have a limiting effect on both sides of the bottle to be cleaned along the first direction. When the bottle to be cleaned is tilted, the two wavy curved surfaces have a limiting effect in both the first and second directions, which can prevent the bottle to be cleaned from tilting.

[0044] The wavy cleaning channel and spray hole 21 replace the nozzles, connecting pipes between nozzles and anti-tipping devices that are set separately in the traditional method, making the cleaning module highly integrated and reducing the module size, thereby reducing the floor space of the production line that uses the cleaning module.

[0045] In some embodiments, the spray hole 21 is disposed on the bottom of the cleaning tank 2.

[0046] This configuration concentrates the spray holes 21 at the bottom of the tank, allowing the water and air to use their own kinetic energy to quickly discharge the residual medicine and droplets from the cleaning tank 2, thus avoiding the problem of secondary pollution caused by the accumulation of residues after cleaning in the cleaning tank 2.

[0047] Specifically, the receiving cavity 11 is located on the top side of the cleaning tank 2, and the bottom of the cleaning tank 2 is provided with a through hole communicating with the receiving cavity 11 as a spray hole 21, so that liquid or gas in the receiving cavity 11 can enter the cleaning tank 2 downward through the spray hole 21.

[0048] The water or airflow ejected from the spray nozzle 21 moves toward the opening of the cleaning tank 2. When the water sprays downwards onto the bottle to be cleaned, the water flows downwards along the outer wall of the bottle to be cleaned, allowing the cleaning liquid mixed with residual medicine to flow quickly from the opening of the cleaning tank 2. The airflow flows downwards and can carry the droplets on the surface of the bottle to be cleaned through the opening of the cleaning tank 2 and discharge them.

[0049] The medium inlet 12 can be located on the top side or the horizontal side wall of the base 1. The edge of the medium inlet 12 can be provided with a skirt plate, which extends horizontally so that the water supply pipe of the water supply unit can be connected to the skirt plate through a flange, so that the water supply unit can communicate with the receiving cavity 11 through the medium inlet. Alternatively, the skirt plate of the medium inlet 12 can be extended in a direction away from the base 1, so that the skirt plate forms a vertical plate structure on the base 1, and the air supply pipe of the air compressor is sleeved on the skirt plate, so that the air compressor can communicate with the receiving cavity 11.

[0050] The inner wall of the cleaning channel is provided with through holes as spray holes 21. Liquid or compressed air temporarily stored in the receiving cavity 11 enters the cleaning channel through the spray holes 21. The liquid forms water mist through the spray holes 21 to rinse the outer wall of the bottle to be cleaned, and the compressed air forms an airflow that blows towards the bottle to be cleaned through the spray holes 21 to dry the bottle. The cleaning channel is located above or below the receiving cavity 11. The spray holes 21 can be set on the inner wall of the cleaning channel near the receiving cavity 11, so that the water mist or airflow sprayed from the spray holes 21 sprays or dries the bottle to be cleaned in a vertical direction; alternatively, the inner walls on both sides of the cleaning channel in the horizontal direction can be provided with spray holes 21, so that the water mist or airflow sprayed from the spray holes 21 sprays or dries the bottle to be cleaned in a horizontal direction from both sides.

[0051] Reference Figure 3 and Figure 4 As shown, in some embodiments, the spray hole 21 extends along the extension direction of the cleaning channel.

[0052] With this configuration, the elongated spray nozzles 21 can form a continuous spraying or drying section, making the water mist or airflow in the cleaning channel evenly distributed. This ensures that the bottle to be cleaned can be evenly and continuously sprayed or dried as it moves within the cleaning channel, thus improving the cleaning effect of the cleaning module on the bottle to be cleaned.

[0053] Specifically, when the cleaning channel is straight, the spray hole 21 is an elongated through hole; when the cleaning channel is curved, the spray hole 21 is arc-shaped on the inner wall of the cleaning tank 2. The liquid sprayed from the spray hole 21 can form a continuous curtain-like water curtain, which extends along the direction of the cleaning channel, allowing the bottle to be cleaned to be continuously sprayed and cleaned as it moves within the cleaning channel. The airflow sprayed from the spray hole 21 can form a continuous airflow wall extending along the cleaning channel, allowing the bottle to be continuously dried as it moves along the cleaning channel.

[0054] Reference Figure 8 and Figure 9 As shown, in some other embodiments, the spray hole 21 includes a plurality of sub-spray holes 211, which are spaced apart along the extension direction of the cleaning channel.

[0055] With this configuration, the water mist or gas sprayed near the sub-nozzle 211 has a stronger local impact on the bottle to be cleaned, resulting in a better cleaning or drying effect. As the bottle moves within the cleaning channel, it passes through multiple sub-nozzles 211 in sequence, allowing it to pass through multiple spray points or drying points. This enables repeated spraying and rinsing or drying of the bottle, improving the cleaning effect of the cleaning module on the bottle.

[0056] Specifically, the number of spray holes 21 can be multiple, and the multiple spray holes 21 are spaced apart along the extension direction of the cleaning channel. Two sub-spray holes 211 can be selected to form a spray hole group, and the two sub-spray holes 211 in a spray hole group are spaced apart along the extension direction perpendicular to the cleaning channel. Multiple spray hole groups are spaced apart along the extension direction of the cleaning channel.

[0057] The liquid or gas in the receiving cavity 11 can enter the cleaning channel through multiple sub-nozzles 211, forming multiple spray points in the cleaning channel. When the bottle to be cleaned moves, the bottle to be cleaned will pass through multiple sub-nozzles 211 in sequence. The liquid or gas sprayed from each spray point will spray or dry the surface of the bottle to be cleaned, forming continuous multi-point cleaning.

[0058] In some embodiments, the receiving cavity 11 includes a first cavity and a second cavity that are isolated from each other, and the first cavity and the second cavity are arranged along the extension direction of the cleaning channel; the medium inlet 12 includes a first opening 121 and a second opening 122, the first opening 121 communicating with the first cavity and the second opening 122 communicating with the second cavity; the inner wall of the cleaning channel is provided with two spray holes 21 arranged along the extension direction of the cleaning channel, and the two spray holes 21 are respectively communicating with the first cavity and the second cavity.

[0059] This configuration, by dividing the receiving chamber into mutually isolated first and second chambers, allows a cleaning module to spray water at different temperatures or utilize circulating water for spraying. A cleaning module can also use airflows of varying speeds or temperatures for drying; this achieves stepped spraying and stepped drying of the bottles to be cleaned, thereby improving the cleaning effect of the cleaning module.

[0060] Specifically, the cleaning tank 2 has an inlet and an outlet at its two ends. The bottle to be cleaned enters the cleaning tank 2 through the inlet and exits through the outlet. The first cavity can be optionally located on the side of the second cavity closer to the inlet. The first opening 121 is connected to the first cavity, allowing liquid or gas to enter the first cavity through the first opening 121; the second opening 122 is connected to the second cavity, allowing liquid or gas to enter the second cavity through the second opening 122.

[0061] Two injection holes 21 are connected to the first cavity and the second cavity respectively, so that the liquid or gas in the first cavity enters the cleaning tank 2 through the corresponding injection hole 21, and the liquid or gas in the second cavity enters the cleaning tank 2 through the corresponding injection hole 21.

[0062] When a cleaning groove 2 extending along a first direction is provided on the substrate 1 as a cleaning channel, the first cavity and the second cavity are arranged along the first direction, and the corresponding injection holes 21 of the first cavity and the second cavity are arranged along the first direction. The injection holes 21 on the cleaning groove 2 corresponding to the first cavity and the second cavity can be selected to extend along the first direction, or the injection holes 21 on the cleaning groove 2 corresponding to the first cavity and the second cavity can be selected to include multiple sub-nozzles 211 arranged at intervals along the first direction.

[0063] When the cleaning module is used to spray the bottle to be cleaned, the first chamber and the second chamber are isolated from each other, so that the first chamber and the second chamber can be connected to different cleaning water sources. For example, hot water is connected to the first chamber and cold water is connected to the second chamber, so that the bottle to be cleaned is first cleaned by the water flow formed by hot water, and then cleaned by the water flow formed by cold water.

[0064] Alternatively, a collection and filtration device can be installed on the outside of the base 1. This device collects and filters the liquid discharged from the cleaning module. The first chamber is connected to hot water, and the second chamber is connected to the collection and filtration device. The bottle to be cleaned is first cleaned by a water jet from the hot water in the corresponding part of the first chamber. When the bottle moves to the corresponding position in the second chamber, the second chamber uses the collected and filtered liquid for a second cleaning. The collection and filtration device enables the recycling of liquid, further reducing the water consumption of the cleaning module.

[0065] When the cleaning module is used to dry the bottle to be cleaned, the first chamber and the second chamber are isolated from each other, so that the first chamber and the second chamber can be connected to air sources with different power. For example, the power of the air source connected to the first chamber is greater than that connected to the second chamber, so that the bottle to be cleaned is first dried by a higher speed airflow at the position corresponding to the first chamber; when the bottle to be cleaned moves to the position corresponding to the second chamber, the bottle to be cleaned is dried by a lower speed airflow for a second time, so as to achieve stepped air blowing.

[0066] Alternatively, the first chamber can be connected to a cold air source, and the second chamber to a hot air source. This allows the bottle to be cleaned to be dried by hot air at the corresponding position in the first chamber after passing through it for the first time, ensuring that the bottle leaves the cleaning tank 2 completely dry.

[0067] Liquid can be introduced into the first chamber, and gas can be introduced into the second chamber. The bottle to be cleaned can be sprayed and dried in a cleaning tank 2 of a base 1.

[0068] In some embodiments, a guide plate 14 is provided in the receiving cavity 11. The guide plate 14 is connected to the inner wall of the receiving cavity 11, and one end of the guide plate 14 extends to the medium inlet 12 and the other end extends to the injection hole 21 to guide liquid or gas from the medium inlet 12 to the injection hole 21.

[0069] With this configuration, the guide plate 14 in the receiving cavity 11 guides the liquid or gas from the medium inlet 12 to the injection hole 21, reducing eddies and resistance losses during the liquid or gas flow process and improving the flow efficiency of the liquid or gas.

[0070] Specifically, the guide plate 14 is connected to the inner wall of the receiving cavity 11 and fixed by welding. The guide plate 14 is an arc-shaped plate. One end of the guide plate extends to the medium inlet 12, forming a medium introduction area between the end and the medium inlet 12; the other end extends to the injection hole 21, with the end located at the inner opening of the injection hole 21, forming a medium outlet area. After the liquid or gas enters the receiving cavity 11 through the medium inlet 12, the liquid or gas moves along the guide plate 14 to the injection hole 21 and enters the cleaning tank 2.

[0071] The cleaning tank 2 includes multiple sub-tanks 22. When each sub-tank 22 is provided with a spray hole 21, the number of guide plates 14 can be selected as multiple. Multiple guide plates 14 are set to correspond to multiple spray holes 21, so that liquid or gas can enter multiple spray holes 21 respectively through multiple guide plates 14.

[0072] In specific use, the cleaning module provided in this application embodiment allows liquid or gas to enter the receiving cavity 11 through the medium inlet 12, where the receiving cavity 11 temporarily stores and stabilizes the liquid or gas. Multiple bottles to be cleaned enter multiple sub-tanks 22 under the drive of a conveyor belt. When the cleaning module is used to spray clean the bottles, the liquid in the receiving cavity 11 enters the corresponding sub-tank 22 through multiple spray holes 21 to form a water mist, which washes away residual liquid on the outer wall of the bottles. When the cleaning module is used to dry the bottles, the gas in the receiving cavity 11 enters the corresponding sub-tank 22 through multiple spray holes 21 to form an airflow, which dries the residual liquid on the outer wall of the bottles.

[0073] A second aspect of this application provides a bottle washing and drying system, including a conveyor belt, a water supply unit, an air compression unit, and two cleaning modules as described in any of the preceding claims; two substrates 1 are arranged along the conveying direction of the conveyor belt, with the upstream substrate 1 serving as a cleaning unit and the downstream substrate 1 serving as a drying unit; the water supply unit is connected to the medium inlet 12 of the cleaning unit to inject water into the receiving cavity 11 of the cleaning unit; the air compression unit is connected to the medium inlet 12 of the drying unit to inject compressed air into the receiving cavity 11 of the drying unit; the conveyor belt is used to transport the bottles to be cleaned sequentially through the cleaning channels of the cleaning unit and the drying unit.

[0074] Specifically, the water supply unit includes a water storage tank and a water pump. The water pump is connected to the medium inlet 12 of the cleaning unit, allowing water from the water storage tank to flow into the medium inlet 12 of the cleaning unit. The air compression unit includes an air compressor, which is connected to the medium inlet 12 of the drying unit, allowing compressed air to be supplied to the receiving cavity 11 of the drying unit by the air compressor.

[0075] The bases 1 of the two cleaning modules are arranged along the conveying direction of the conveyor belt. The base 1 located upstream of the conveyor belt serves as a cleaning unit, and its receiving cavity 11 is connected to the water supply unit for spraying water onto the bottle to be cleaned. The base 1 located downstream of the conveyor belt serves as a drying unit, and its receiving cavity 11 is connected to the air compression unit for spraying compressed air onto the cleaned bottle to remove residual moisture from the surface.

[0076] After the system is started, the water pump of the water supply unit delivers cleaning water to the receiving cavity 11 of the cleaning unit through the pipeline, and the air compressor of the air compression unit delivers compressed air to the receiving cavity 11 of the drying unit.

[0077] The bottles to be cleaned are fed in from the front end of the conveyor belt and move into the cleaning tank 2 of the cleaning unit. Cleaning water is sprayed onto the outer wall of the bottles through spray holes 21 to wash away residual medicine and other contaminants. After cleaning, the bottles continue to move with the conveyor belt and leave the cleaning unit, then enter the cleaning tank 2 of the drying unit. At this time, compressed air in the receiving cavity 11 of the drying unit is sprayed out at high speed through spray holes 21 to dry the residual moisture on the outer wall of the bottles.

[0078] Mounting plates 13 are provided on opposite edges of the base 1, and the mounting plates are connected to the support structure of the conveyor belt to mount the base 1 onto the conveyor belt.

[0079] By connecting two cleaning modules in series, continuous operation of bottle washing and drying is achieved. Compared with traditional separate equipment, the production process is more compact. The cleaning module can reduce water consumption and air source energy consumption, thereby improving the working efficiency of the bottle washing and drying system and reducing the operating cost of the bottle washing and drying system.
