Description

Technical Field

[0001] This invention relates to a cleaning and drying device, and more particularly to a cleaning and drying device for brush-type tools. Background Technology

[0002] In fields such as fine art painting, professional film and television makeup, and the maintenance of precision optical instruments, brushes (such as watercolor brushes, oil paintbrushes, makeup brushes, and industrial dust brushes) are indispensable basic working media. Whether it's the harmonious blending of colors, the delicate blending of makeup, or the cleaning of tiny crevices, everything directly depends on the cleanliness, softness, and cohesion of the brush fibers. Especially in high-frequency usage scenarios such as art school teaching, large-scale studio training, or commercial photography studios, the daily usage of brushes is extremely high. If paint, oil, or dust adhering to the brush bristles is not removed promptly and effectively, the residue will not only cause the bristles to harden and split, severely shortening the lifespan of expensive tools, but also easily lead to paint mixing or bacterial growth in subsequent use, directly affecting the quality of artwork and safety. Therefore, achieving efficient and non-destructive cleaning and maintenance of brushes is a rigid requirement within the industry.

[0003] Currently, the industry mainly uses traditional manual cleaning or electrically assisted cleaning equipment for the daily cleaning of such tools. Manual cleaning is highly dependent on the operator's experience, which is not only time-consuming and labor-intensive, but also difficult to ensure consistent cleaning when dealing with a large number of tools. To solve the efficiency problem, existing electric cleaning technologies mostly adopt mechanical drive principles. They typically use a motor to drive a clamping device, causing the brush to rotate and rub in the cleaning solution, or they use physical scrapers or silicone particles at the bottom of the cleaning tank for contact brushing. Some equipment also uses the vortex effect of water flow to replace tedious manual rubbing in order to quickly remove surface dirt.

[0004] However, while existing electric cleaning equipment has improved cleaning efficiency to some extent, it still faces the technical challenge of balancing thorough cleaning with tool protection in practical applications. Existing solutions often rely solely on mechanical friction or water rinsing—a single physical method—which often proves inadequate when dealing with the dense, dirt-accumulating areas at the base of the bristles (the nozzle opening). Excessively increasing mechanical friction or extending brushing time to achieve root cleanliness can easily damage, deform, or even cause the fragile bristle fibers to fall off. Conversely, gentler cleaning methods struggle to penetrate the bristle gaps and thoroughly remove deep-seated dirt. Furthermore, most existing equipment lacks a complete functional design, generally missing a post-cleaning drying process. The brushes remain damp after cleaning, preventing immediate use. This incomplete drying severely restricts workflow continuity, and prolonged retention of residual moisture can easily damage the brush handle. Summary of the Invention

[0005] The purpose of this invention is to provide a cleaning and drying device for brush-type tools, which can achieve deep, non-destructive cleaning and rapid drying of the brush bristles, solving the problem that it is difficult to balance thorough cleaning and protection in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cleaning and drying device for brush-type tools, comprising a body and a cleaning cylinder disposed on the body, and further comprising: A rotary cleaning mechanism is installed on the cleaning cylinder for mechanical cleaning of brush-type tools; A gas-liquid synergistic gas supply system is installed inside the machine body, including a gas supply device, a heating component, an airflow switching device, and an aeration pipe communicating with the inside of the cleaning cylinder. The outlet end of the gas supply device is connected to the inlet end of the airflow switching device. The airflow switching device also has a first outlet end and a second outlet end. The first outlet end is connected to the aeration pipe, and the second outlet end is connected to the heating component. By controlling the airflow switching device, the gas supply device can be selectively connected to either the aeration pipe or the heating component. When in the cleaning state, the airflow output by the air supply device enters the aeration pipe through the first air outlet, forms bubbles in the cleaning cylinder, and works with the rotating cleaning mechanism to perform cleaning. When in a dry state, the airflow output by the air supply device enters the heating component through the second air outlet, and after heating, it forms hot air to dry the brush-like tools.

[0007] Preferably, the rotating cleaning mechanism includes a fixed end cap and multiple sets of rotating cleaning units. The fixed end cap is disposed on the top of the cleaning cylinder. The multiple sets of rotating cleaning units are evenly distributed circumferentially on the fixed end cap. Each set of rotating cleaning units includes a drive unit mounted on the fixed end cap and a cleaning component located inside the cleaning cylinder. The cleaning component is connected to the drive unit and is driven to rotate by the drive unit.

[0008] Preferably, the cleaning assembly includes a rotating shaft and a flexible brush body disposed on the rotating shaft. The rotating shaft is vertically arranged, with its upper end connected to the output end of the drive unit. The flexible brush body is connected to the lower end of the rotating shaft, and multiple flexible brush bodies are arranged in the center of the cleaning cylinder to form a cleaning space for accommodating brush-like tools.

[0009] Preferably, the aeration pipe extends to the bottom of the cleaning cylinder and is connected to an aeration ring. The aeration ring is located below the flexible brush body, and the aeration ring has several upward-facing air outlets. The air outlets are used to disperse the airflow into the cleaning cylinder to form uniformly distributed turbulent bubbles.

[0010] Preferably, the bottom of the cleaning cylinder is connected to a drain pipe, and a solenoid valve for controlling the on / off state is provided on the drain pipe. A collection component is provided inside the machine body, and the collection component is located below the drain pipe for receiving waste liquid discharged from the drain pipe.

[0011] Preferably, the collection assembly includes a guide plate and a receiving box slidably installed inside the machine body. The guide plate is inclinedly disposed inside the machine body and located below the outlet of the drain pipe. The receiving box is located below the guide plate and is used to receive the waste liquid after it has been guided by the guide plate.

[0012] Preferably, it further includes a miniature high-frequency vibration component disposed on the cleaning cylinder or inside the machine body, the miniature high-frequency vibration component being used to generate high-frequency mechanical vibration to assist in removing dirt from brush-like tools.

[0013] Preferably, the heating assembly includes a heating housing and an electric heating element. The heating housing is disposed on the machine body and close to the cleaning cylinder. The heating housing has a drying chamber for accommodating brush-like tools. The electric heating element is fixed inside the heating housing and is thermally connected to the side wall of the cleaning cylinder. The heating housing also has an air inlet, which is connected to the second air outlet of the airflow switching device. The airflow output by the air supply device enters the heating housing through the second air outlet, is heated by the electric heating element, and then enters the drying chamber to dry the brush-like tools.

[0014] Preferably, the machine body is provided with a control component, which is electrically connected to the rotary cleaning mechanism, the air supply device, the heating component, and the airflow switching device, respectively, for controlling the switching of the equipment between the cleaning state and the drying state, and adjusting the rotation speed of the rotary cleaning mechanism and the air output power of the air supply device; wherein, the drive unit is a variable frequency motor, a stepper motor, or a brushless DC motor, and the air supply device is a centrifugal fan, an axial flow fan, or an air pump.

[0015] Preferably, the control component further includes a current detection module, which is electrically connected to the drive unit and is used to monitor the operating current of the drive unit in real time. When the monitored operating current exceeds a preset threshold, the control component controls the drive unit to reduce its speed.

[0016] Compared with existing technologies, the advantages of this invention are as follows: This device achieves dual reuse and functional transformation of a single air supply device in different processes by controlling the airflow switching device. In the cleaning operation, the airflow output by the air supply device is precisely guided to the aeration pipe at the bottom of the cleaning cylinder, continuously generating a large number of high-energy turbulent bubbles in the liquid medium. These bubbles utilize cavitation effect and upward buoyancy to penetrate deep into the fiber gaps and roots of the brush-like tools. The resulting flexible vibration force and the mechanical friction of the rotating cleaning mechanism form a gas-liquid dual-phase synergistic effect, thoroughly removing stubborn dirt while significantly reducing physical damage to the fragile bristles by utilizing the buffering characteristics of the bubbles. In the drying operation, the airflow path is quickly switched to the heating component, converting the airflow into hot air that directly acts on the wet brush, achieving rapid drying.

[0017] The significant advantage of this structure is that it greatly improves the system's integration and energy efficiency. It eliminates the redundant design of traditional equipment where the power sources for cleaning and drying are separated. With just one air supply system, it can meet the dual needs of flexible deep cleaning and efficient hot air drying. It effectively solves the industry pain points of existing technologies, such as the difficulty in cleaning the roots of the brush, the easy damage to the bristles by simple mechanical brushing, and the inability to use the brush immediately after cleaning.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: As shown in the figure, a cleaning and drying device for brush-type tools includes a body 1 and a cleaning cylinder 2 disposed on the body 1, and further includes: The rotary cleaning mechanism 3 is mounted on the cleaning cylinder 2 and is used for mechanical cleaning of brush-type tools. The gas-liquid synergistic air supply system 4 is installed inside the body 1 and includes an air supply device 5, a heating component 6, an airflow switching device 7, and an aeration pipe 8 that communicates with the inside of the cleaning cylinder 2. The air outlet of the air supply device 5 is connected to the air inlet of the airflow switching device 7. The airflow switching device 7 also has a first air outlet 9 and a second air outlet 10. The first air outlet 9 is connected to the aeration pipe 8, and the second air outlet 10 is connected to the heating component 6. By controlling the airflow switching device 7, the air supply device 5 can be selectively connected to either the aeration pipe 8 or the heating component 6. When in the cleaning state, the airflow output by the air supply device 5 enters the aeration pipe 8 through the first air outlet 9, forms bubbles in the cleaning cylinder 2 and works with the rotating cleaning mechanism 3 to clean. When in a dry state, the airflow output by the air supply device 5 enters the heating component 6 through the second air outlet 10, and after heating, it forms hot air to dry the brush-like tools.

[0022] Example 2: As shown in the figure, unlike Example 1, the rotating cleaning mechanism 3 includes a fixed end cap 11 and multiple sets of rotating cleaning units 12. The fixed end cap 11 is disposed on the top of the cleaning cylinder 2. The multiple sets of rotating cleaning units 12 are evenly distributed on the fixed end cap 11 in a circumferential direction. Each set of rotating cleaning units 12 includes a drive unit 13 mounted on the fixed end cap 11 and a cleaning component 14 located inside the cleaning cylinder 2. The cleaning component 14 is connected to the drive unit 13 and is driven to rotate by the drive unit 13.

[0023] The rotating cleaning mechanism 3 uses a top-mounted fixed end cap 11 as a stable support platform, achieving a water and electricity separation layout where the drive unit 13 is placed on top and the cleaning components 14 are suspended inside. While ensuring that electrical components are kept away from liquids to guarantee operational safety, multiple circumferentially distributed rotating cleaning units 12 construct a surrounding cleaning area inside the cleaning cylinder 2. Its core working principle is that multiple cleaning components 14 can rotate simultaneously under the drive of their respective drive units 13, thereby providing all-round coverage and brushing of brush-like tools placed in the central area from different directions. This multi-point concurrent operation mode not only completely eliminates the dead corners that may exist in single-sided cleaning, significantly improving cleaning efficiency and thoroughness, but also forms a centripetal cleaning force through the synergistic effect of multiple units, effectively preventing tools from shaking or shifting violently due to uneven force during the cleaning process, further enhancing the stability of equipment operation and the controllability of the cleaning process.

[0024] In this embodiment, the cleaning component 14 includes a rotating shaft 15 and a flexible brush body 16 disposed on the rotating shaft 15. The rotating shaft 15 is vertically arranged, and its upper end is connected to the output end of the drive unit 13. The flexible brush body 16 is connected to the lower end of the rotating shaft 15, and multiple flexible brush bodies 16 surround the center of the cleaning cylinder 2 to form a cleaning space for accommodating brush-like tools.

[0025] This structure uses a vertically suspended power transmission method, with the rotating shaft 15 stably transmitting the rotational torque of the top drive unit 13 to the flexible brush body 16 located at the bottom. This ensures that the cleaning components can penetrate deep into the cleaning fluid for effective operation. Furthermore, due to the use of flexible brush bodies and a centrally enclosed spatial layout, when multiple flexible brush bodies 16 rotate synchronously, a high-density surrounding friction cleaning field is constructed in the central area of ​​the cleaning cylinder 2. This design can not only adapt to brushes of different diameters and shapes, avoiding rigid wear on the tool surface through flexible contact, but also apply cleaning force to the tool from all sides to the center simultaneously, achieving all-round coverage and brushing of dirt. This effectively solves the problems of low cleaning efficiency on one side and easy formation of cleaning dead corners. At the same time, the enclosed cleaning space also plays a role in assisting in limiting and centering the inserted tools, further improving the stability and consistency of the cleaning process.

[0026] In addition to the manual handling of the brushes to be cleaned, this device further includes a detachable retaining cap that is installed at the top opening of the cleaning cylinder 2. The top surface of this retaining cap has a through-hole for the handle of the brush to pass through, and retaining caps with different through-hole diameters are available to accommodate handles of varying thicknesses. The advantage of this design is that it provides both stable tool positioning and maintains a clean working environment. Firstly, the fitting through-hole effectively constrains the passing handle, ensuring the brush head remains stably positioned in the center of the cleaning cylinder 2, preventing violent shaking or swaying during cleaning due to uneven force. Secondly, the closed cylinder seals the top opening of the cleaning cylinder 2, creating a relatively enclosed cleaning chamber that physically blocks splashing droplets generated by rotating cleaning or bubble turbulence, effectively preventing cleaning fluid overflow.

[0027] In this embodiment, the aeration pipe 8 extends to the bottom of the cleaning cylinder 2 and is connected to the aeration ring 17. The aeration ring 17 is located below the flexible brush body 16, and the aeration ring 17 has several upward-facing air outlets 18. The air outlets 18 are used to disperse the airflow into the cleaning cylinder 2 to form uniformly distributed turbulent bubbles.

[0028] The above structure adopts a bottom-mounted annular air distribution scheme. By extending the aeration pipe 8 to the bottom of the cleaning cylinder 2 and connecting it to the aeration ring 17 located directly below the cleaning component 14, and having several upward-facing air outlets 18 distributed circumferentially on the surface of the ring, the concentrated airflow can be dispersed by the air outlets 18, and a uniformly distributed rising bubble curtain can be constructed at the bottom of the cleaning cylinder 2. These bubbles move vertically upward under the drive of buoyancy and pass through the cleaning component 14 and brush-like tools above.

[0029] The advantage of the above design is that it achieves all-round coverage of air-liquid synergistic cleaning. The high-density turbulent air bubbles can penetrate deep into the gaps and roots of the bristle fibers for micro-rinsing, effectively compensating for the cleaning dead corners that may exist in simple mechanical rotation. At the same time, the uniform air distribution method drives the overall tumbling and flow of the cleaning liquid, avoiding the problem of excessive local turbulence damaging the bristles or insufficient turbulence leading to incomplete cleaning, thereby greatly improving the thoroughness and consistency of deep cleaning.

[0030] In this embodiment, the bottom of the cleaning cylinder 2 is connected to a drain pipe 19, and a solenoid valve 20 for controlling the on and off is provided on the drain pipe 19. A collection component 21 is provided inside the body 1. The collection component 21 is located below the drain pipe 19 and is used to receive the waste liquid discharged from the drain pipe 19.

[0031] The aforementioned structure utilizes the gravitational potential energy at the bottom of the cleaning cylinder 2 in conjunction with the on / off control of the solenoid valve 20. After the cleaning process is completed, the channel is automatically opened to quickly guide the waste liquid into the built-in collection component 21. The significant advantage of this design is that it greatly improves the convenience and automation of equipment operation. The introduction of the solenoid valve 20 eliminates the cumbersome manual valve operation and enables seamless connection from cleaning to drainage to drying. At the same time, the built-in collection component 21 realizes centralized temporary storage and closed management of waste liquid, eliminating the equipment's dependence on external fixed drainage pipes 19 or water tanks. This allows the device to be flexibly deployed in scenarios such as art studio desktops where there are no direct drainage facilities, ensuring both a clean working environment and convenient centralized treatment of waste liquid by the user.

[0032] Example 3: As shown in the figure, unlike Example 2, the collection component 21 includes a guide plate 22 and a receiving box 23 that is slidably installed in the body 1. The guide plate 22 is inclinedly arranged inside the body 1 and located below the outlet of the drain pipe 19. The receiving box 23 is located below the guide plate 22 and is used to receive the waste liquid after it has been guided by the guide plate 22.

[0033] This structure utilizes an inclined guide plate 22 as an intermediate buffer medium to transform the waste liquid falling vertically from the drain pipe 19 into a smooth, diffused flow along the slope, eventually converging into the receiving box 23 below. This effectively solves the splashing problem that may occur when liquid drips directly, ensuring the cleanliness of the collected waste liquid. At the same time, the sliding and pull-out receiving box 23 structure allows users to easily remove the collection container for emptying and cleaning without having to move the entire machine, greatly improving the convenience of equipment maintenance and the human-machine interaction experience.

[0034] In this embodiment, a miniature high-frequency vibration component 24 is also provided on the cleaning cylinder 2 or inside the body 1. The miniature high-frequency vibration component 24 is used to generate high-frequency mechanical vibration to assist in peeling off dirt from brush-like tools.

[0035] The aforementioned structure incorporates a micro high-frequency vibration component 24 as a third physical auxiliary cleaning method. The energy waves generated by the high-frequency mechanical oscillation are transmitted to the surface and internal fibers of the brush-like tool via the wall of the cleaning cylinder 2 or the liquid medium. This effectively breaks down the adhesion between stubborn pigments and the bristles. In particular, for the dense area at the base of the bristles that is difficult to reach by simply relying on rotational friction or bubble turbulence, the high-frequency oscillation can quickly loosen and peel off deep dirt, improving the ability to remove old and dried pigments. At the same time, the non-contact nature of the high-frequency oscillation avoids the risk of bristle damage caused by excessively increasing mechanical friction in pursuit of cleanliness.

[0036] In this embodiment, the heating assembly 6 includes a heating housing 25 and an electric heating element 26. The heating housing 25 is disposed on the body 1 and close to the cleaning cylinder 2. The heating housing 25 has a drying chamber 27 for accommodating brush-like tools. The electric heating element 26 is fixed inside the heating housing 25 and is thermally connected to the side wall of the cleaning cylinder 2. The heating housing 25 is also provided with an air inlet 28, which is connected to the second air outlet 10 of the airflow switching device 7. The airflow output by the air supply device 5 enters the heating housing 25 through the second air outlet 10, is heated by the electric heating element 26, and then enters the drying chamber 27 to dry the brush-like tools.

[0037] The aforementioned structure utilizes an electric heating element 26 as a shared heat source. On one hand, it heats the air introduced via the airflow switching device 7, creating high-temperature hot air that enters the drying chamber 27 to quickly dry brush-like tools. On the other hand, the electric heating element 26 can be selectively activated according to user settings or program presets, thereby transferring heat to the liquid medium inside the cleaning cylinder 2 through thermal conduction with the side wall of the cleaning cylinder 2. The significant advantages of this design are that it greatly improves the system's energy efficiency and cleaning performance, achieving dual utilization of heat energy. It ensures the high efficiency of the drying process while using conductive heat to assist in heating the cleaning liquid. The warm water's stronger dissolving power for pigments significantly improves cleaning thoroughness. Simultaneously, this compact, integrated layout effectively reduces the equipment's size.

[0038] In this embodiment, the airflow switching device is a one-position three-way solenoid valve. Its inlet is connected to the air supply device, its first outlet is connected to the aeration pipe, and its second outlet is connected to the air inlet. By controlling the on and off of the two-position three-way solenoid valve, the airflow can be selectively connected between the first outlet and the second outlet.

[0039] In this embodiment, a control component 29 is provided on the machine body 1. The control component 29 is electrically connected to the rotary cleaning mechanism 3, the air supply device 5, the heating component 6, and the airflow switching device 7, respectively. It is used to control the switching of the equipment between the cleaning state and the drying state, and to adjust the rotation speed of the rotary cleaning mechanism 3 and the air output power of the air supply device 5. The drive unit 13 is a variable frequency motor, a stepper motor, or a brushless DC motor, and the air supply device 5 is a centrifugal fan, an axial flow fan, or an air pump.

[0040] The aforementioned structure, through control component 29, achieves centralized and unified management of the drive, air supply, and heating units. Furthermore, it utilizes high-performance drive components such as variable frequency motors, stepper motors, or brushless DC motors to replace traditional fixed-speed motors, providing a foundation for precise speed control. With the dynamic adjustment of motor speed and air supply power by control component 29, the equipment breaks through the limitations of traditional cleaning machines' single mechanical mode, outputting matched physical cleaning force and airflow intensity for brushes of different bristle types and sizes. Combined with a stable air source device such as a centrifugal fan or air pump, the system not only ensures automated connection of the entire cleaning and drying process but also achieves a flexible balance between gentle maintenance and powerful decontamination at the hardware level, effectively preventing over- or under-cleaning problems caused by unadjustable speed.

[0041] In this embodiment, the control component 29 further includes a current detection module 30, which is electrically connected to the drive unit 13 and is used to monitor the operating current of the drive unit 13 in real time. When the monitored operating current exceeds a preset threshold, the control component 29 controls the drive unit 13 to reduce its speed.

[0042] When the cleaning component 14 rotates, the frictional resistance between the bristles and the brush-like tool is directly converted into the load torque of the drive unit 13 (motor), which manifests as a change in the operating current. The current detection module 30, acting as a feedback sensor, captures this value in real time and transmits it to the control component 29. Once an abnormal increase in current is detected (exceeding a preset threshold), it means that the current physical friction is too great, possibly due to a brush with an excessively large diameter, excessively stiff bristles, or a stuck brush head. At this time, the control component 29 immediately executes a speed reduction command, reducing the output power of the drive unit 13.

[0043] This prevents the fragile and precious bristles (such as animal hair) from being forcibly broken or twisted due to excessive mechanical shearing force, giving the equipment the ability to adapt to different working conditions. It can also effectively prevent the motor from overheating and burning out due to prolonged overload operation, and avoid the transmission structure from breaking teeth or breaking due to excessive torque, significantly improving the durability and safety of the equipment.

[0044] For example, suppose a user is using the device to clean a large, stiff-bristled boar bristle oil paintbrush, and the device is in standard cleaning mode by default (assuming an initial spin speed of 300 rpm).

[0045] Insertion phase: When the user inserts the large oil painting brush into the center of the cleaning component 14 of the cleaning tube 2, the cleaning component 14 (flexible brush body 16) experiences significant physical resistance when rotating due to the large diameter of the brush head and the stiffness of the bristles.

[0046] Monitoring phase: As the resistance increases, the drive unit 13 (motor) must output greater torque in order to maintain a speed of 300 rpm, causing its operating current to surge from the normal 0.5A to 1.2A instantaneously (assuming the preset safety threshold is 1.0A).

[0047] Judgment and Execution: The current detection module 30 instantly captures a current value of 1.2A and feeds it back to the control component 29. The control component 29 determines that the value exceeds the safety threshold of 1.0A and identifies the current risk of overload / violent scrubbing.

[0048] Protection action: The control component 29 immediately sends a command to the drive unit 13 to automatically reduce the speed from 300 rpm to 150 rpm.

[0049] Result: After the rotation speed was reduced, the friction between the bristles decreased, and the operating current dropped back to a safe range. At this time, the equipment continued to clean in a gentler low-speed mode, which not only cleaned the paint but also ensured that the stiff-bristled brush would not fall out due to strong pulling, while also preventing the motor from overheating.

[0050] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
