Description

Technical Field

[0001] This utility model relates to the field of razor cleaning technology, and in particular to a cleaning device. Background Technology

[0002] During daily use of electric shavers, a large amount of stubble and dander accumulates inside the shaver head, hereinafter referred to as impurities, requiring maintenance through a dedicated cleaning device. In existing technology, shaver cleaning devices typically employ a design where the cleaning fluid container is directly connected to the cleaning tank. The cleaning fluid is delivered from the container to the tank via an inlet pipe to rinse the shaver head. However, this structure has a significant drawback: during the cleaning process, some of the impurities removed from the shaver flow into the cleaning tank with the cleaning fluid and further enter the pump body that pumps the cleaning fluid through the inlet pipe.

[0003] Specifically, the accumulation of impurities within the pump body has several negative impacts. First, impurities can clog critical pump components, such as the impeller or valves, preventing the pump from functioning properly and reducing pumping efficiency. Second, impurity accumulation increases pump maintenance costs, requiring frequent cleaning to maintain normal operation. Furthermore, even if impurities do not affect the pump's internal structure, over long-term use, they flow back into the cleaning fluid container through the return and inlet pipes. Impurities naturally accumulate in the positions corresponding vertically to the return and inlet pipes. While accumulation in the return pipe generally does not affect the inlet flow, accumulation near the inlet pipe can impede the pumping of the cleaning fluid, leading to a decrease in cleaning effectiveness. Utility Model Content

[0004] In order to overcome at least one of the defects of the prior art, the present invention provides a cleaning device that can solve the problem of impurities flowing back through the inlet pipe, which affects the service life of the pump body and the pumping of the cleaning fluid.

[0005] The technical solution adopted by this utility model to solve its problem is:

[0006] A cleaning apparatus, comprising:

[0007] A cleaning tank for cleaning electrical equipment, the cleaning tank having a liquid inlet and a first liquid return outlet;

[0008] A cleaning fluid container is used to hold cleaning fluid. The cleaning fluid container has an outlet and a second return outlet. An inlet pipe is provided between the inlet and the outlet and is connected through the inlet pipe. A return pipe is provided between the first return outlet and the second return outlet and is connected through the return pipe.

[0009] Pump body, the pump body being mounted on the liquid inlet pipe;

[0010] The cleaning tank is equipped with a check valve at the inlet to prevent the cleaning fluid in the cleaning tank from flowing into the inlet pipe through the inlet, or the inlet pipe is equipped with a check valve to prevent the cleaning fluid in the cleaning tank from flowing into the pump body through the inlet pipe.

[0011] Furthermore, the check valve includes a check part and a limiting part. One end of the check part is rotatably connected to the cleaning tank so that the check part can rotate around the rotatable connection point between the check part and the cleaning tank. The limiting part is located on the side of the check part facing the liquid outlet. When the check part blocks the liquid inlet, the limiting part abuts against the side wall of the liquid inlet to prevent the check part from rotating towards the liquid outlet.

[0012] Alternatively, one end of the check valve is rotatably connected to the inlet pipe, so that the check valve can rotate around the rotatable connection point between the check valve and the inlet pipe. The limiting part is located on the side of the check valve facing the outlet. When the check valve blocks the inlet pipe, the limiting part abuts against the pipe wall of the inlet pipe to prevent the check valve from rotating towards the outlet.

[0013] By adopting the above solution and installing a check valve including a check and a limiting part at the inlet or inlet pipe, the cleaning fluid can only flow unidirectionally from the cleaning fluid container to the cleaning tank. This effectively prevents liquid and impurities in the cleaning tank from flowing back into the pump body, thereby reducing pump malfunctions and damage caused by impurity accumulation, improving pumping efficiency, and extending pump life. Furthermore, this design also protects the quality of the cleaning fluid, improves the cleaning effect, and enhances the stability and reliability of equipment operation.

[0014] Furthermore, the check valve is located at the liquid inlet and is integrally formed with the cleaning tank.

[0015] By adopting the above solution and designing the check valve and the cleaning tank as a single unit, the structure reduces the number of components, which helps to reduce manufacturing and maintenance costs. More importantly, the check valve and the cleaning tank are integrally molded, and the elasticity of the connection between the check valve and the cleaning tank is used to reset the check valve, thus eliminating the need for a complex spring structure between the check valve and the cleaning tank.

[0016] Furthermore, the cleaning tank is provided with an overflow port, which is connected to the return liquid pipe.

[0017] By adopting the above solution,

[0018] Furthermore, the cleaning tank is provided with a plurality of protrusions, all of which are spaced apart circumferentially along the cleaning tank to clamp the electrical equipment, and the overflow port is located between two adjacent protrusions.

[0019] By adopting the above solution, an overflow port is installed in the cleaning tank and connected to the return pipe, which can effectively avoid the problem of overflow caused by excessive cleaning liquid, keep the work area clean and safe, prevent damage to electrical equipment caused by excessive liquid, ensure the stable operation of the cleaning system, help maintain an appropriate liquid level, and improve cleaning efficiency and effect.

[0020] Furthermore, it also includes a drying mechanism, which has an air vent connected to the cleaning tank and located above the overflow port.

[0021] By adopting the above solution, the air outlet of the drying mechanism is connected to the cleaning tank and located above the overflow port, which can not only accelerate the drying process of the equipment after cleaning, but also prevent the cleaning liquid from flowing back into the drying mechanism, thereby improving operational safety and equipment service life.

[0022] Furthermore, the cleaning fluid container is provided with a groove, the outlet is located in the groove of the cleaning fluid container, the outlet is provided with a filter element, and the pump body and the inlet pipe are both located on the side of the filter element away from the cleaning fluid container.

[0023] By adopting the above-mentioned design, the cleaning fluid container is equipped with a groove and the outlet is located within the groove. A filter element is installed at the outlet, and the pump body and inlet pipe are located on the side of the filter element away from the cleaning fluid container. This design effectively filters out large particulate impurities in the cleaning fluid, preventing them from entering the pump body and inlet pipe. This reduces pump malfunctions and damage caused by impurity accumulation, improves pumping efficiency, and extends pump life. Simultaneously, it ensures the cleanliness of the cleaning fluid delivered to the cleaning tank, enhancing the cleaning effect. Furthermore, the groove design provides assembly space for the pump body, helping to optimize the overall structural layout.

[0024] Furthermore, the bottom of the cleaning fluid container is provided with a sedimentation tank.

[0025] By adopting the above solution, a sedimentation tank is provided at the bottom of the cleaning fluid container, which can promote the sedimentation of impurities in the cleaning fluid and concentrate them at the bottom of the tank, reducing the amount of these impurities that are pumped back into the system, thereby protecting the pump body and the equipment to be cleaned from contamination, while maintaining the cleanliness of the cleaning fluid.

[0026] Furthermore, it also includes:

[0027] A switch, wherein an indicator light is provided;

[0028] A light panel is disposed around the opening of the cleaning tank;

[0029] The controller, the switch and the lamp panel are all electrically connected to the controller.

[0030] By adopting the above solution, and integrating a switch with indicator lights, a light panel located around the opening of the cleaning tank, and a controller electrically connected to it into the cleaning device, not only is the convenience of user operation and the safety of equipment use improved, but the intuitive status display and intelligent control functions also enhance the visual management and automation level of the equipment, making the cleaning process more efficient and intelligent, and timely reminding users to pay attention to the equipment's operating status and potential problems.

[0031] Furthermore, the lamp board is provided with multiple lamp beads, and the multiple lamp beads emit a variety of colors, and all the lamp beads are electrically connected to the lamp board.

[0032] By adopting the above solution, the light panel is equipped with multiple LED beads that can emit various colors. All LED beads are electrically connected to the light panel. The different color light changes can clearly indicate the various working states of the cleaning device, such as standby, running, completed, or faulty, which enhances the accuracy of operation and the user's interactive experience. At the same time, it also improves the aesthetics of the equipment and the possibility of personalized settings.

[0033] Furthermore, it also includes a cleaning fluid balance detection device, which has a detection probe that extends into the cleaning fluid container.

[0034] By adopting the above scheme, the remaining amount of cleaning fluid in the cleaning fluid container is detected by a detection probe to prevent the operation from running without cleaning fluid.

[0035] In summary, the cleaning device provided by this utility model has the following technical effects:

[0036] 1. Installing a check valve at the inlet or inlet pipe effectively prevents cleaning fluid and impurities in the cleaning tank from flowing back into the cleaning fluid container or pump body through the inlet pipe. The check valve uses a rotating structure to achieve unidirectional flow control, ensuring that the cleaning fluid can only flow from the cleaning fluid container to the cleaning tank and will not flow in the opposite direction. This prevents impurities from entering the outlet pipe and, consequently, from entering the pump body located on the outlet pipe. This reduces pump malfunctions and damage caused by impurity accumulation, improves pumping efficiency, and extends pump life.

[0037] 2. The use of a check valve makes the cleaning process smoother and reduces problems with cleaning fluid pumping caused by impurities accumulating near the inlet pipe. Attached Figure Description

Detailed Implementation

[0050] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described and discussed below with reference to the accompanying drawings. Obviously, what is described here is only a part of the examples of this invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the protection scope of this invention.

[0051] To facilitate understanding of the embodiments of this utility model, further explanations and descriptions will be provided below with reference to the accompanying drawings and specific embodiments. These embodiments do not constitute a limitation on the embodiments of this utility model.

[0052] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0053] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0054] See Figures 1-11 This utility model discloses a cleaning device, including a cleaning tank 1, a cleaning liquid container 2, and a pump body 5. The cleaning tank 1 is used for cleaning electrical equipment and has an inlet 11 and a first return port 12. The cleaning liquid container 2 is used to hold the cleaning liquid and has an outlet 21 and a second return port 22. An inlet pipe 3 is provided between the inlet 11 and the outlet 21 and is connected through the inlet pipe 3. A return pipe 4 is provided between the first return port 12 and the second return port 22 and is connected through the return pipe 4. The pump body 5 is mounted on the inlet pipe 3. A check valve 6 is provided at the inlet 11 or the inlet pipe 3 to prevent the cleaning liquid in the cleaning tank 1 from flowing into the inlet pipe 3 through the inlet 11.

[0055] Specifically, the cleaning tank 1 is used for cleaning electrical equipment (such as electric shavers). The cleaning tank 1 has an inlet 11 for receiving cleaning fluid and a first return port 12 for returning the cleaned fluid to the cleaning fluid container 2. The cleaning fluid container 2 is used to store the cleaning fluid and has an outlet 21 and a second return port 22. The outlet 21 is connected to the inlet 11 of the cleaning tank 1 via an inlet pipe 3, and the second return port 22 is connected to the first return port 12 of the cleaning tank 1 via a return pipe 4. A pump body 5 is installed on the inlet pipe 3 and is used to pump the cleaning fluid from the cleaning tank 1 into the cleaning tank 1 via the inlet pipe 3. The cleaning tank 1 has a check valve 6 at the inlet 11, or the inlet pipe 3 has a check valve 6. When the check valve 6 is installed at the inlet 11 of the cleaning tank 1, it can prevent the cleaning liquid in the cleaning tank 1 from flowing into the inlet pipe 3 through the inlet 11, thereby minimizing the flow of cleaning liquid containing impurities in the cleaning tank 1 into the inlet pipe 3, thus preventing impurities from entering the pump body 5 and preventing the impact caused by the accumulation of impurities near the pump body 5. When the check valve 6 is installed in the inlet pipe 3, it can prevent the cleaning fluid in the cleaning tank 1 from flowing to the pump body 5 through the inlet pipe 3. That is, the check valve 6 is installed in the inlet pipe 3 between the pump body 5 and the inlet port 11. Thus, the cleaning fluid flowing back from the cleaning tank 1 is restricted by the check valve 6. The cleaning fluid will not continue to flow towards the inlet pipe 3 where the pump body 5 and the inlet pipe 3 are connected. This effectively prevents the cleaning fluid with impurities from affecting the service life of the pump body 5 and prevents impurities from accumulating near the pump body 5. The cleaning fluid that enters the inlet pipe 3 in the direction of the check valve 6 towards the inlet port 11 will be flushed into the cleaning tank 1 by the new cleaning fluid during the next cleaning and will not affect the normal use of the cleaning device.

[0056] Among them, the check valve 6 can be a check valve, a one-way valve, a solenoid valve, a flap, etc., which can be opened during the cleaning process so that the cleaning fluid pumped by the pump body 5 can flow into the cleaning tank 1 continuously. At the same time, it can prevent the cleaning fluid in the cleaning tank 1 from flowing back to the pump body 5 during the cleaning process and when the pump body 5 finishes working.

[0057] See Figure 6 As shown, in some embodiments, the check valve 6 includes a check part 61 and a limiting part 62. One end of the check part 61 is rotatably connected to the cleaning tank 1 so that the check part 61 can rotate around the rotatable connection point between the check part 61 and the cleaning tank 1. The limiting part 62 is located on the side of the check part 61 facing the liquid outlet 21. When the check part 61 blocks the liquid inlet 11, the limiting part 62 abuts against the side wall of the liquid inlet 11 to prevent the check part 61 from rotating toward the liquid outlet 21.

[0058] Alternatively, one end of the check valve 61 is rotatably connected to the inlet pipe 3 so that the check valve 61 can rotate around the rotatable connection point between the check valve 61 and the inlet pipe 3. The limiting part 62 is located on the side of the check valve 61 facing the outlet 21. When the check valve 61 blocks the inlet pipe 3, the limiting part 62 abuts against the pipe wall of the inlet pipe 3 to prevent the check valve 61 from rotating towards the outlet 21.

[0059] Specifically, the check valve 6 has two implementation methods:

[0060] In the first embodiment, the check valve 61 is rotatably connected to the cleaning tank 1. One end of the check valve 61 is rotatably connected to the inlet 11 of the cleaning tank 1 and can rotate around the connection point. The limiting part 62 is located on the side of the check valve 61 facing the outlet 21 and is used to abut against the side wall of the inlet 11 when the check valve 61 blocks the inlet 11, preventing the check valve 61 from rotating towards the outlet 21.

[0061] Working principle:

[0062] Forward flow (cleaning fluid from cleaning fluid container 2 to cleaning tank 1):

[0063] When the pump body 5 is working, the cleaning fluid enters the inlet 11 of the cleaning tank 1 through the inlet pipe 3.

[0064] The pressure of the cleaning fluid pushes the check valve 61 to rotate away from the outlet 21, causing the check valve 61 to disengage from the inlet 11 and allowing the cleaning fluid to flow into the cleaning tank 1.

[0065] Reverse flow (cleaning fluid from cleaning tank 1 to cleaning fluid container 2):

[0066] When the pump body 5 stops or the liquid level in the cleaning tank 1 drops, the check part 61 rotates towards the liquid outlet 21 due to gravity or the absence of pressure, but the limiting part 62 abuts against the side wall of the liquid inlet 11, preventing the check part 61 from continuing to rotate.

[0067] In the second embodiment, the check valve 61 is rotatably connected to the inlet pipe 3. One end of the check valve 61 is rotatably connected to the inlet pipe 3 (near the cleaning tank 1) and can rotate around the connection point. The limiting part 62 is located on the side of the check valve 61 facing the outlet 21 and is used to abut against the pipe wall when the check valve 61 blocks the inlet pipe 3 to prevent the check valve 61 from rotating towards the outlet 21.

[0068] Working principle:

[0069] Forward flow (cleaning fluid from cleaning fluid container 2 to cleaning tank 1):

[0070] The cleaning fluid enters the cleaning tank 1 through the inlet pipe 3. The liquid pressure pushes the check valve 61 to rotate away from the outlet 21, causing the check valve 61 to disengage from the inlet pipe 3 and allowing the cleaning fluid to pass through.

[0071] Reverse flow (cleaning fluid from cleaning tank 1 to cleaning fluid container 2):

[0072] When the pump body 5 stops or the liquid level in the cleaning tank 1 drops, the check part 61 rotates towards the liquid outlet 21 due to gravity or the absence of pressure, but the limiting part 62 abuts against the wall of the liquid inlet pipe 3, preventing the check part 61 from continuing to rotate.

[0073] The check valve 61 blocks the inlet pipe 3 to prevent the cleaning fluid and impurities in the cleaning tank 1 from flowing back to the pump body 5 or the cleaning fluid container 2.

[0074] The above-mentioned linkage design of check part 61 and limit part 62 realizes the function of mechanical one-way valve, ensuring that the cleaning fluid can only flow in one direction (from cleaning fluid container 2 to cleaning tank 1).

[0075] To prevent impurities from flowing back to the pump body 5 or filter element 24 with the cleaning fluid, thus avoiding blockage and damage.

[0076] In addition, the rotatable connection between the check valve 61 and the cleaning tank 1 can be a rotatable connection through a rotating shaft, or a flexible connection based on material properties, and is not limited here.

[0077] It should be noted that, for ease of illustration in the accompanying drawings, the gaps between the check valve 61 and the surrounding walls, and between the limiting part 62 and the wall of the outlet pipe, are increased. In actual production and use, the check valve 61 can be completely fitted with the surrounding walls to improve the check valve effect. Similarly, during production and use, the limiting part 62 can also be fitted with the side wall of the outlet pipe when the check valve 61 is in its initial position to prevent the check valve 61 from rotating in the opposite direction. Furthermore, even if there are small gaps between the check valve 61 and the surrounding walls, and between the limiting part 62 and the wall of the outlet pipe, the small gaps greatly reduce the possibility of impurities entering the outlet pipe. Even if impurities do enter the outlet pipe, the small gaps will not affect the service life of the pump body 5, nor will they cause impurities to accumulate near the pump body 5.

[0078] See Figure 5 and Figure 6 As shown, in some embodiments, the check valve 6 is located at the inlet 11, and the check valve 6 is integrally formed with the cleaning tank 1. The check valve 6 and the cleaning tank 1 are integrally formed by processes such as injection molding, casting, or machining to form a unified structural unit. Furthermore, the check valve 61 and the limiting part 62 are directly connected to the edge of the inlet 11, without the need for additional assembly.

[0079] See Figure 1 , Figure 5 and Figure 7 As shown, in some embodiments, the cleaning tank 1 is provided with an overflow port 13, which is connected to the return liquid pipe 4.

[0080] Specifically, the overflow port 13 is located on the side wall of the cleaning tank 1, and its specific position can be adjusted according to the shape of the cleaning tank 1 and the liquid level requirements. The overflow port 13 is connected to the second return port 22 of the cleaning liquid container 2 through the return pipe 4, forming a circulation loop for the cleaning liquid. When the first return port 12 becomes blocked, the overflow port 13 in the cleaning tank 1 can discharge the cleaning liquid in the cleaning tank 1 to the cleaning liquid container 2 through the overflow port 13, preventing the cleaning liquid from overflowing onto the table.

[0081] See Figures 1-5 As shown, in some embodiments, the cleaning tank 1 is provided with a plurality of protrusions 14, all of which are spaced apart along the circumference of the cleaning tank 1 for clamping electrical equipment, and the overflow port 13 is provided between two adjacent protrusions 14.

[0082] Specifically, the raised strips 14 are spaced apart circumferentially along the cleaning tank 1. The number of raised strips 14 is designed according to the size of the cleaning tank 1 and the type of equipment (such as an electric shaver), typically 3-6. The shape of the raised strips 14 can be designed as strip, arc, or wave to accommodate electrical equipment of different sizes. The raised strips 14 physically clamp the electrical equipment (such as the shaver) to prevent the equipment from shaking or floating during cleaning. Furthermore, the setting of the raised strips 14 changes the contact surface of the electrical equipment from the existing side wall of the cleaning tank 1 to the outer surface of the raised strips 14. The overflow port 13 is located between adjacent raised strips 14, that is, the overflow port 13 is an opening opened in the tank wall of the cleaning tank 1, and there is a gap between the overflow port 13 and the outer surface of the electrical equipment, reducing the risk of contact between the equipment and the overflow port 13, allowing the cleaning fluid to flow out smoothly from the overflow port 13, and avoiding blockage of the overflow port 13 due to obstruction by the electrical equipment.

[0083] See Figure 1 , Figures 4-6 As shown, in some embodiments, the cleaning device further includes a drying mechanism 7, which has an air outlet 71 that is connected to the cleaning tank 1 and is located above the overflow port 13.

[0084] Specifically, the air vent 71 of the drying mechanism 7 can be an air inlet 71 or an air outlet 71. Whether the air inlet 71 is connected to the cleaning tank 1 or the air outlet 71 is connected to the cleaning tank 1, the air drying mechanism 7 can accelerate the air flow in the cleaning tank 1, thereby achieving the effect of accelerating drying. The air vent 71 is located above the overflow port 13. When the cleaning liquid circulation is abnormally blocked, the cleaning liquid in the cleaning tank 1 will return through the overflow port 13, and will not flow into the drying mechanism 7 through the air vent 71 due to the blockage of the cleaning liquid in the cleaning tank 1, thus improving the safety of the cleaning device.

[0085] Additionally, a heating device can be added to the bottom or side wall of the cleaning tank 1 as needed to improve the shaver drying efficiency. Alternatively, a heating device can be installed at the air outlet 71 of the drying mechanism 7 to further improve drying efficiency.

[0086] See Figure 5 and Figure 8 As shown, in some embodiments, the cleaning fluid container 2 is provided with a groove 23, the outlet 21 is provided in the groove 23 of the cleaning fluid container 2, the outlet 21 is provided with a filter element 24, and the pump body 5 and the inlet pipe 3 are both located on the side of the filter element 24 away from the cleaning fluid container 2.

[0087] Specifically, the filter element 24 intercepts large particles of impurities in the cleaning fluid at the outlet 21, allowing only the cleaning fluid to enter the outlet pipe. The filter element 24, in conjunction with the check valve 6, creates a relatively clean outlet channel between the filter element 24 and the check valve 6. The pump body 5 is connected to this outlet pipe, further protecting it. Furthermore, the filter element 24 significantly reduces the amount of impurities entering the outlet pipe, protecting the pump body 5's lifespan and ensuring the cleanliness of the cleaning fluid supplied to the cleaning tank 1, thus guaranteeing the cleaning effect. The groove 23 in the cleaning fluid container 2 provides space for the pump body 5 to be assembled.

[0088] See Figure 8 and Figure 9 As shown, in some embodiments, the bottom of the cleaning fluid container 2 is provided with a sedimentation tank 25.

[0089] Specifically, the bottom of the cleaning fluid container 2 is provided with a sedimentation tank 25 to settle impurities that enter the cleaning fluid container 2, so as to prevent the water flow generated when the pump body 5 pumps the cleaning fluid from stirring the impurities in the cleaning fluid.

[0090] Furthermore, multiple sedimentation tanks 25 can be evenly distributed in the cleaning liquid container 2. Since the bottom area of ​​the cleaning liquid container 2 is fixed, the more sedimentation tanks 25 are set, the smaller the projected area of ​​a single sedimentation tank 25 becomes. The smaller the sedimentation tank 25, the less likely the impurities precipitated in it are to be affected by the agitation of the cleaning liquid by the pump body 5. This greatly reduces the impurities precipitated in the sedimentation tank 25 being agitated into the cleaning liquid outside the sedimentation tank 25. It also reduces the impurities agitated into the sedimentation tank 25 from participating in the cleaning of electrical equipment with the cleaning liquid, thus ensuring the cleaning effect and the service life of the pump body 5.

[0091] See Figure 1 , Figure 4 and Figure 5 As shown, in some embodiments, the cleaning device further includes a switch 81, a lamp panel 82, and a controller 83. An indicator light 811 is provided at the switch 81, and the lamp panel 82 is located on the periphery of the opening of the cleaning tank 1. Both the switch 81 and the lamp panel 82 are electrically connected to the controller 83.

[0092] Specifically, switch 81 is used to turn on the cleaning device. An indicator light 811 is located at switch 81 to indicate the power-on status. A light panel is positioned around the opening of the cleaning tank 1. Since the cleaning tank 1 is located, its opening generally needs to face vertically upwards. The light panel 82 is positioned around the opening of the cleaning tank 1, and its operation status is displayed by turning it on, off, or adjusting its color. The controller 83 is used to receive and process signals, and to adjust the corresponding lights based on the signals. Specific adjustment methods are not limited here.

[0093] See Figure 1 , Figure 4 and Figure 5 As shown, in some embodiments, the lamp board 82 is provided with multiple lamp beads, and the multiple lamp beads emit multiple colors. All lamp beads are electrically connected to the lamp board 82.

[0094] Specifically, the light panel 82 is equipped with multiple independent LED beads (such as LEDs), which can be evenly distributed around the perimeter of the opening of the cleaning tank 1. The goal is to ensure that the light is clearly visible on the top of the cleaning device, allowing the user to easily discern its status. The status of the cleaning device is indicated by changes in the color of the LED beads, such as the connection status between the cleaning device and electrical equipment, the on / off status of the pump body 5, and the on / off status of the drying mechanism 7, etc. Specific details are not limited here.

[0095] See Figures 10-11 As shown, in some embodiments, the cleaning apparatus further includes a cleaning fluid balance detection device, which has a detection probe 9 that extends into the cleaning fluid container 2.

[0096] Specifically, the cleaning fluid level detection device has a detection probe 9, which can be electrically connected to the controller 83 to send the monitored data to the controller 83 for unified control. Alternatively, the detection probe 9 can also have its own control circuit board for alarm control, alerting the user that the cleaning fluid is low. Alternatively, the detection probe 9 can also be electrically connected to the controller 83 to provide a low cleaning fluid level indication.

[0097] The depth of the detection probe 9 can be adjusted according to the length of the detection probe 9 inserted into the cleaning fluid container 2 as needed. The specific dimensions are not limited here, as long as they meet the user's needs.

[0098] When the detection probe 9 is electrically connected to the controller 83, a C-type terminal 831 can be set on the controller 83 to facilitate the insertion and soldering of the detection probe 9.
