[0039] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model 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 utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. It should be noted that, unless otherwise specified, the embodiments and feature vectors in this application can be arbitrarily combined with each other.

[0040] To address the problems existing in related technologies, this application provides a vessel cleaning brush and a vessel cleaning device. The vessel cleaning brush includes a scraper and a fixing plate, which are detachably connected. The fixing plate covers a portion of the scraper's surface. A buffer layer and a cleaning cloth are disposed on the surface of the scraper, and at least a portion of the buffer layer and cleaning cloth are located between the scraper and the fixing plate. In this application, by setting a fixing plate detachably from the scraper to fix the buffer layer and cleaning cloth to the scraper, the buffer layer and cleaning cloth can be directly removed and replaced with a brand new buffer layer and cleaning cloth, or a specific type of buffer layer and cleaning cloth, after each cleaning, which helps to improve cleaning efficiency.

[0041] According to an exemplary embodiment of this application, such as Figure 1 , Figure 2 and Figure 6 As shown, this application embodiment provides a vessel cleaning brush 100. The vessel cleaning brush 100 can be installed on a drive device 200 such as a servo motor. The drive device 200 outputs torque to drive the vessel cleaning brush 100 to rotate, and scrapes off impurities attached to the inner wall of the vessel through cyclic friction to achieve the cleaning function.

[0042] like Figure 2 and Figure 3 As shown, the vessel cleaning brush 100 includes a scraper 10, which can be connected to the output shaft 201 of the drive device 200. The surface of the scraper 10 is used to mount components such as a cleaning cloth (described in detail below) that can effectively remove impurities. The scraper 10 has a specific shape design; in one example, see [reference needed]. Figure 3 The image shows a scraper 10 with a curved cleaning surface, which allows the buffer layer and cleaning cloth to deform smoothly and better match the shape of the inner wall of the vessel, thus improving the cleaning effect. In another example (not shown in the figures), the scraper 10 has an elliptical cleaning surface to better conform to the curved inner wall of the vessel.

[0043] like Figure 3As shown, the vessel cleaning brush 100 also includes a fixing plate 20, a buffer layer, and a cleaning cloth. The fixing plate 20 is detachably connected to the scraper 10, and the fixing plate 20 can fix the buffer layer and the cleaning cloth to the surface of the scraper 10. It is understood that the buffer layer and the cleaning cloth are disposable consumables, and they will wear down after each use, resulting in a significant decrease in cleaning performance. To achieve the original cleaning effect, multiple processes are usually required. Therefore, to ensure the cleaning effect of continuous operation, the buffer layer and the cleaning cloth can be used as disposable consumables. For example, each vessel can use two buffer layers and two cleaning cloths, that is, they should be replaced halfway through the cleaning process.

[0044] The buffer layer can be made of hard, absorbent, and moisture-locking materials such as EVA, PVA, PU, ​​or rubber sponges, providing cushioning to prevent the scraper 10 from scratching the mixing vessel wall. The buffer layer is approximately 4mm thick. Cleaning cloths include household scouring pads, abrasive scouring pads, polishing cloths, and lint-free cloths. The type of cleaning cloth can be selected based on the scenario and mixing steps; for example, polishing cloths can be used to remove scratches and rust.

[0045] See Figure 3 Each vessel cleaning brush 100 is typically provided with at least two fixing plates 20. The two fixing plates 20 are used to fix the buffer layer and the two ends of the cleaning cloth respectively, while the part of the cleaning cloth located between the two ends is used for cleaning.

[0046] like Figure 3 As shown, the scraper 10 has a cylindrical structure (scraper body 11), and two fixed plates 20 are located at two equal division points of the scraper 10, with a 90° angle between the two fixed plates 20. The outer peripheral surface of the scraper 10 located at the 270° arc angle between the two fixed plates 20 is covered by a buffer layer and a cleaning cloth.

[0047] In this embodiment, a fixing plate 20 that is detachable from the scraper 10 is provided to fix the buffer layer and cleaning cloth to the scraper 10. After each cleaning, the buffer layer and cleaning cloth can be directly removed and replaced with a brand new buffer layer and cleaning cloth, or a specific type of buffer layer and cleaning cloth, which helps to improve cleaning efficiency and cleaning effect.

[0048] In one exemplary embodiment, such as Figure 1 and Figure 2 As shown in the figure, this application provides a vessel cleaning brush 100, which includes a scraper 10 and a fixing plate 20. The scraper 10 and the fixing plate 20 are detachably connected. The fixing plate 20 covers part of the surface of the scraper 10. The surface of the scraper 10 is provided with a buffer layer and a cleaning cloth, and at least part of the structure of the buffer layer and the cleaning cloth is located between the scraper 10 and the fixing plate 20.

[0049] In this embodiment, as Figure 3 As shown, the scraper 10 has a cylindrical structure (i.e., the scraper body 11, which will be described in detail later). A threaded hole 10a is provided on the outer circumferential surface of the cylindrical structure. First pre-set through holes 20a are provided on the fixing plate 20, the buffer layer, and the cleaning cloth. The column of the first fastener 50 (e.g., a screw) sequentially penetrates the fixing plate 20, the cleaning cloth, and the buffer layer. The thread on the outer circumferential surface of the column engages with the threaded hole 10a. The head of the first fastener 50 is located on the side of the fixing plate 20 opposite to the scraper body 11, and the head provides pressure towards the scraper body 11 to fix the buffer layer and the cleaning cloth to the surface of the scraper body 11. In this embodiment, a screw or other first fastener 50 is used to form a detachable connection, which has advantages such as low requirements for through hole machining, simple structure, and convenient assembly and disassembly.

[0050] In some alternative implementations (not shown in the accompanying drawings), a detachable connection can also be formed by means of snap-fit ​​or other methods.

[0051] Among them, such as Figure 3 As shown, a first anti-slip layer 30 is provided in the area directly opposite the scraper 10 and the fixed plate 20. The first anti-slip layer 30 is located between the buffer layer and the scraper 10. (See reference...) Figure 2 and Figure 3 A second anti-slip layer 40 is provided on the side of the fixing plate 20 facing the scraper 10, and the second anti-slip layer 40 is disposed between the cleaning cloth and the fixing plate 20. The first anti-slip layer 30 and the second anti-slip layer 40 are, for example, anti-slip rubber pads. By providing the first anti-slip layer 30 and the second anti-slip layer 40 on both sides of the buffer layer and the cleaning cloth, the cleaning cloth and the buffer layer are prevented from moving relative to the scraper 10 and falling off.

[0052] In some alternative embodiments, a third anti-slip layer may be provided between the buffer layer and the cleaning cloth, the area of ​​which may be similar to that of the first anti-slip layer 30 and the second protective layer.

[0053] Among them, such as Figure 3 As shown, the scraper 10 includes a scraper body 11 and a connecting arm 12. The connecting arm 12 is used to connect the scraper body 11 to the output shaft 201 of the drive device 200. Part of the outer peripheral surface of the scraper body 11 forms a cleaning surface. The buffer layer, cleaning cloth and fixing plate 20 are all installed on the scraper body 11 by fasteners.

[0054] The connecting arm 12 can have different shapes to adjust the relative position of the scraper body 11 and the drive device 200. This allows for better contact between the scraper body 11 and the inner wall of the vessel of different shapes without changing the position of the drive device 200, thereby improving the cleaning effect. For example, the connecting arm 12 can be straight, L-shaped, etc.

[0055] See Figure 3 The scraper 10 can be detachably connected to the output shaft 201 of the drive device 200 through the second preset through hole 123 and the second fastener 60. For example, the second preset through hole 123 is provided on the connecting arm 12, and the second fastener 60 passes through the second preset through hole 123 and engages with the threaded groove on the output shaft 201.

[0056] Among them, such as Figures 3 to 5 As shown, the connecting arm 12 includes a first connecting member 121 and a second connecting member 122 connected together. One of the first connecting member 121 and the second connecting member 122 is connected to the scraper body 11, and the other is connected to the output shaft 201 of the drive device 200. (See reference...) Figures 3 to 5 The first connector 121 and the second connector 122 have a preset included angle of 0° to 180° with each other.

[0057] In one example, see Figure 4 The diagram shows that the preset included angle between the first connector 121 and the second connector 122 is equal to 180°, that is, the connecting arm 12 is in the shape of a straight plate. The vessel cleaning brush 100 provided in this example can be used as a side wall cleaning brush 102, which has the effect of being easy to install.

[0058] See another example. Figure 3 The diagram shows a preset included angle of 90° between the first connector 121 and the second connector 122, meaning that the connecting arm 12 is L-shaped. The vessel cleaning brush 100 provided in this example can also serve as a bottom wall cleaning brush 101, offering advantages such as easy installation and high installation strength.

[0059] In yet another example, see Figure 5 It shows that the preset included angle between the first connector 121 and the second connector 122 is greater than 90°, for example, the preset included angle is equal to 135°.

[0060] As can be seen from the above, for the same type of buffer layer and cleaning cloth, by installing the buffer layer and cleaning cloth on scrapers 10 with different preset angles, different areas of the buffer layer and cleaning cloth can be made to contact the inner wall of the vessel, thereby making full use of the entire surface of the buffer layer and cleaning cloth, improving the utilization rate of disposable consumables, and saving costs.

[0061] Among them, such as Figure 2 and Figure 3 As shown, the first connector 121 and the second connector 122 of the connecting arm 12 of the scraper 10 are an integral structure. The scraper 10 is made of materials such as polytetrafluoroethylene, and can be formed by processes such as injection molding and 3D printing. The connecting arm 12 of the scraper 10 made by the integral molding process has the advantages of simple manufacturing process, high precision and high structural consistency.

[0062] In some alternative implementations, such as Figure 3 and Figure 5 As shown, the first connector 121 and the second connector 122 are rotatably connected by a first preset pivot (not shown in the figure). The first connector 121 rotates relative to the second connector 122 around the first preset pivot to adjust the size of the preset angle, thereby adjusting the contact surface between the buffer layer and the cleaning cloth and the inner wall.

[0063] According to yet another exemplary embodiment of this application, such as Figure 1 and Figure 6 As shown, this embodiment also provides a vessel cleaning device, which includes a housing 300, a drive device 200, and a vessel cleaning brush 100 provided in any of the foregoing embodiments of this application. The output shaft 201 of the drive device 200 is connected to the vessel cleaning brush 100. The housing 300 is used to provide mounting points and protection for other structures.

[0064] Among them, such as Figure 1 and Figure 6 As shown, the vessel cleaning brush 100 includes a bottom wall cleaning brush 101, which is used to clean the bottom wall of the vessel. The vessel cleaning device also includes a planetary gear set 400, which includes a central gear 401 and at least one ring gear 402. The ring gear 402 is arranged along the circumferential direction of the central gear 401 and meshes with the central gear 401. The central gear 401 is connected to the output shaft 201 of the drive device 200, and the ring gear 402 is connected to the bottom wall cleaning brush 101. The drive device 200 outputs torque to drive the central gear 401 to rotate. The central gear 401 transmits power to the ring gear 402, causing the ring gear 402 to rotate around the circumferential direction of the central gear 401 while also rotating on its own axis. This generates sufficient friction between the bottom wall cleaning brush 101 and the interior of the vessel, which helps to improve cleaning efficiency.

[0065] In one example, see Figure 1 and Figure 6 The planetary gear set 400 includes two ring gears 402, and the vessel cleaning device is equipped with two bottom wall cleaning brushes 101, which are respectively connected to the two ring gears 402.

[0066] Among them, such as Figure 1 and Figure 6 As shown, the vessel cleaning brush 100 also includes a side wall cleaning brush 102. In the circumferential direction of the central gear 401, the side wall cleaning brush 102 is connected to the central gear 401 and located between adjacent bottom wall cleaning brushes 101.

[0067] In one example, see Figure 1One sidewall cleaning brush 102 is provided. In another example (not shown in the attached figure), two sidewall cleaning brushes and two bottom wall cleaning brushes are provided, with the two bottom wall cleaning brushes and the two sidewall cleaning brushes arranged alternately.

[0068] The vessel cleaning device also includes a water washing assembly (not shown in the attached diagram), which includes a water tank, water pipes, and a nozzle. The nozzle is capable of spraying cleaning fluid onto the inner wall of the vessel. In one example, the nozzle can be mounted on the side wall cleaning brush 102. When the nozzle sprays cleaning fluid toward the bottom wall, it can prevent the cleaning fluid from being blocked by the bottom wall cleaning brush 101, thus ensuring the cleaning fluid achieves its proper function.

[0069] The vessel cleaning device provided in this application embodiment can be used in the following ways:

[0070] First, cover the scrapers of the side wall cleaning brush and bottom wall cleaning brush with a buffer layer and a cleaning cloth, and secure them with a fixing plate. Then, mount the bottom wall cleaning brush onto the agitator 500 of the vessel cleaning device (refer to...). Figure 1 and Figure 6 On the bottom, the gap between the bottom cleaning brush and the bottom wall is approximately 4mm. This gap can be adjusted by changing to different sized scrapers or scrapers with different preset angles. In this step, the cleaning cloth can be a scouring pad containing abrasive.

[0071] Next, pour the cleaning solution into the vessel, or pour an equal amount of cleaning solution into the water tank of the vessel cleaning device. The total amount of cleaning solution should be about one-fifth of the total volume of the vessel. Set the internal temperature of the vessel to about 55℃~65℃.

[0072] Then, control the drive unit to output power, driving the stirring paddle, bottom wall cleaning brush, and side wall cleaning brush to rotate. The output shaft of the drive unit can rotate at a speed of 4.8 rpm to 5.2 rpm for about 20 minutes, then increase the speed to 20 rpm and continue stirring for about 30 minutes. In this step, use slow rotation at the beginning to avoid damage to the vessel cleaning device due to excessive impurities at the beginning of cleaning.

[0073] Next, pour out the cleaning solution and the removed impurities from the vessel. Replace the buffer layer and cleaning cloth on the vessel cleaning device with brand new ones. In this step, the new scouring pad can be a household-grade scouring pad.

[0074] Next, pour the cleaning solution back into the vessel, filling it to about one-fifth of its volume. Set the internal temperature of the vessel to approximately 55℃–65℃. Then, control the drive unit to output power, driving the stirring paddle, bottom wall cleaning brush, and side wall cleaning brush to rotate. The output shaft of the drive unit can rotate at 25 rpm for approximately 20 minutes.

[0075] Next, pour out the cleaning solution and the removed impurities from the vessel. Replace the buffer layer and cleaning cloth on the vessel cleaning device with brand new ones, and add two more cleaning cloths (lint-free cloths), which need to be soaked in the cleaning solution.

[0076] Finally, the drive unit outputs power to rotate the stirring paddle, bottom wall cleaning brush, and side wall cleaning brush. The output shaft of the drive unit can rotate at 10 rpm for approximately 10 minutes.
