Description

Technical Field

[0001] This utility model relates to the field of cleaning devices, and more particularly to a cleaning mechanism and a cleaning machine having the cleaning mechanism. Background Technology

[0002] With the improvement of people's living standards and the increasing demands for cleaning in commercial and public spaces, cleaning equipment is being used more and more widely in various environments. For soft furnishings such as sofas, chairs, curtains, and carpets, specialized cleaning machines are typically needed for deep cleaning to remove dust, stains, and bacteria attached to the fabric fibers. For hard surfaces such as floors, stairs, and building exteriors, equipment with strong scrubbing capabilities and spray systems is required. These different application scenarios place diverse functional demands on cleaning machines, especially in terms of cleaning efficiency, operational flexibility, and adaptability to various materials.

[0003] Existing cleaning machines typically consist of a water tank, pressure pump, nozzles, brush heads, motor, and control system. They can clean various surfaces through the combined action of water jets and brushing. During cleaning, the roller brush rubs against the ground, and cleaning fluid is sprayed onto the ground through nozzles located on the side or outside of the equipment, assisting the roller brush in cleaning. However, some devices have a relatively simple cleaning disc drive structure, usually driven directly by a single motor. Furthermore, the cleaning fluid delivery path is often dispersed, and spraying from the external side of the equipment makes it difficult to achieve uniform liquid distribution, resulting in inadequate cleaning in certain areas or waste of liquid. Therefore, a new cleaning machine is proposed to address these problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a cleaning mechanism and a cleaning machine with the cleaning mechanism, aiming to improve the problem that the existing technology has a relatively dispersed design of the cleaning liquid delivery path, which sprays from the outside side of the equipment, making it difficult to achieve uniform distribution of the liquid and causing local insufficient cleaning or liquid waste.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cleaning mechanism includes a base, a fixed plate inside the base, a drive mechanism on the top of the fixed plate, and a mounting bracket at the bottom of the fixed plate. A bent joint is fixedly connected inside the mounting bracket, and a hollow rotating shaft is located inside the mounting bracket. The drive mechanism drives the hollow rotating shaft to rotate. A connector is fixedly connected to the bottom of the side wall of the hollow rotating shaft, and a cleaning tray is located outside the connector. A water inlet pipe is fixedly connected inside the base, and the water inlet pipe can be connected to the bent joint via a pipe. The hollow rotating shaft is located at the center of the cleaning tray.

[0011] As a further description of the above technical solution:

[0012] A stabilizing column is fixedly connected to the bottom of the first fixing plate, and a second fixing plate is fixedly connected to the bottom of the stabilizing column.

[0013] As a further description of the above technical solution:

[0014] Two bearings are fixedly connected to the outer wall of the hollow shaft. The outer ring of the top bearing is fixedly connected inside the mounting bracket, and the outer ring of the bottom bearing is fixedly connected inside the second fixing plate. The driven gear is located between the two bearings.

[0015] As a further description of the above technical solution:

[0016] The cleaning mechanism is provided with a connecting handle on its side wall, and the cleaning mechanism and the connecting handle are connected by a fixing mechanism.

[0017] As a further description of the above technical solution:

[0018] A connecting rod is slidably connected inside the connecting handle, and a grip is slidably connected to the side wall of the connecting rod. The connecting rod and the connecting handle are fixed together by a seat post clamp, and the connecting rod and the grip are also fixed together by a seat post clamp.

[0019] As a further description of the above technical solution:

[0020] The fixing mechanism includes a side ear and a connecting handle. The side ear is located on one side of the top of the base. The side ear has a toothed groove on its opposite side. The connecting handle is located between the side ears. A toothed block is fixedly connected to one end of the connecting handle. An adjusting bolt is threaded inside the side ear. The adjusting bolt has two symmetrically arranged threads on its side wall. The connecting handle is rotatably connected to the middle section of the adjusting bolt's side wall.

[0021] As a further description of the above technical solution:

[0022] The tooth block matches the tooth groove.

[0023] As a further description of the above technical solution:

[0024] Two seat post clamps are provided. The bottom seat post clamp is located at the joint of the connecting handle and the connecting rod. The connecting rod has a handle on its side wall, and the handle is connected to the connecting rod through a sliding ring. The top seat post clamp is located at the joint between the sliding ring and the connecting rod.

[0025] This utility model has the following beneficial effects:

[0026] 1. In this utility model, a hollow rotating shaft supported by double bearings, combined with gear transmission, enables the cleaning disc to rotate stably under the drive of a motor. After the motor starts, the driving gear drives the driven gear to rotate, and the driven gear, through the connected hollow rotating shaft, drives the cleaning disc to rotate horizontally. The double bearing structure effectively reduces axial and radial runout, improves rotational accuracy and operational stability, thereby ensuring efficient and stable cleaning. Simultaneously, the hollow rotating shaft has a connected water channel inside, allowing the cleaning fluid delivered by the inlet pipe to reach the center of the cleaning disc directly along the hollow channel and be evenly sprayed out from the center of the disc surface. This central water inlet and rotating water outlet structure prevents spray deviation, ensuring the cleaning fluid is evenly distributed on the floor surface. Combined with the rotational motion, this achieves efficient cleaning. Placing the hollow rotating shaft at the center of the cleaning disc not only facilitates direct water flow but also ensures symmetrical force distribution during disc rotation, reducing vibration and improving the consistency of the cleaning trajectory coverage, further enhancing the cleaning effect and work quality.

[0027] 2. In this utility model, by rotating the adjusting bolt, the two side ears are moved to the sides, causing the toothed block to separate from the toothed groove, thus releasing the restriction of the side ears on the connecting handle. Then, the connecting rod can be moved to change its angle. After the angle is determined, the adjusting bolt is rotated in the opposite direction to make the side ears press against the connecting handle again and make the toothed block re-engage with the toothed groove, ensuring the stability of the equipment during use. The angle adjustment and locking can be completed by rotating the adjusting bolt, simplifying the operation steps. The re-engagement of the toothed block with the toothed groove ensures the reliability of the equipment during use and effectively improves the comfort of using the equipment.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Reference Figures 1-3This utility model provides an embodiment of a cleaning mechanism, including a base 1. A fixing plate 2 is disposed within the base 1. A stabilizing column 6 is fixedly connected to the bottom of the fixing plate 2, and a second fixing plate 3 is fixedly connected to the bottom of the stabilizing column 6. This enhances the stability of the overall structure, provides stronger support, and ensures the smooth operation and durability of the equipment during high-frequency, high-intensity cleaning operations. A driving mechanism is disposed at the top of the fixing plate 2, serving as the driving source for providing rotational power. A mounting frame 7 is disposed at the bottom of the fixing plate 2, with a bent connector 8 fixedly connected inside the mounting frame 7 for directional delivery of the cleaning fluid. A hollow rotating shaft 9 is disposed inside the mounting frame 7, and the driving mechanism drives the hollow rotating shaft 9 to rotate. A connector 12 is fixedly connected to the bottom of the side wall of the hollow rotating shaft 9, and a cleaning disc 13 is disposed outside the connector 12 for direct contact with the surface of the product for rotational scrubbing and cleaning. The cleaning disc 13 can be disassembled and replaced according to the type of object being cleaned, allowing for changes in brush size to accommodate different cleaning scenarios and... The base 1 is made of a material with a water inlet pipe 14 fixedly connected inside. The water inlet pipe 14 and the elbow joint 8 can be connected through a pipe to realize a closed loop of cleaning fluid from the outside of the equipment to the inside of the cleaning components. The hollow rotating shaft 9 is located in the center of the cleaning plate 13, ensuring that the water flow is evenly distributed in the center of the cleaning plate 13 during the cleaning process, improving the cleaning coverage and uniformity. The mounting frame 7, elbow joint 8 and hollow rotating shaft 9 are all equipped with water channels, and the three are connected. The water channels can circulate cleaning fluid, and can also spray steam or cold water for brushing. The interconnected water channels allow the liquid to flow continuously, reducing dead corners and liquid stagnation areas, and preventing the cleaning fluid from staying in certain places for a long time, which would affect the cleaning effect. At the same time, the design of water channel interconnection and liquid flow helps to prevent impurities from accumulating inside the pipes, and avoids the cleaning fluid from affecting the cleaning efficiency due to blockage. Moreover, the smooth flow of liquid inside the pipes means that the cleaning effect will be more uniform, and there will be no situation where some parts are not cleaned thoroughly, thus improving the cleaning efficiency.

[0037] The drive mechanism consists of a motor 5 and a drive gear 4 connected to the motor 5. A driven gear 10 is fixedly connected to the side wall of the hollow shaft 9. The driven gear 10 meshes with the drive gear 4. Through gear engagement, the purpose is to produce bubbles, steam, and water in the middle. In addition, the main unit can issue commands to the motor 5 to adjust its speed. The transmission ratio between the drive gear 4 and the driven gear 10 is 1:1. Two bearings 11 are fixedly connected to the outer wall of the hollow shaft 9. The hollow shaft 9 is fixed at both ends by the two bearings 11, forming a double-support structure. Compared with single-bearing support, this can more effectively limit the shaft's wobbling and eccentric movement. The outer ring of the top bearing 11 is fixedly connected inside the mounting bracket 7, and the outer ring of the bottom bearing 11 is fixed... Connected inside the fixed plate 2 3, the outer ring of the bearing 11 is fixed on different components, which can ensure that the rotating shaft always runs on the central axis. This reduces the uneven load caused by eccentric rotation, thereby improving coaxiality. When the bearing is stable and maintains coaxial operation, there will be no irregular friction or impact due to eccentricity or axial wobbling during rotation, thus significantly reducing mechanical vibration and operating noise. Moreover, the smooth operation of the hollow rotating shaft 9 means that the cleaning disc 13 installed on it can also rotate at a uniform speed and stably, thereby improving the uniformity and overall effect of cleaning. The driven gear 10 is located between the two bearings 11, which helps to balance the force and reduce friction during gear operation, making the whole machine run more smoothly.

[0038] Reference Figures 4-5The cleaning mechanism has a connecting handle 18 on its side wall. The cleaning mechanism and the connecting handle 18 are connected by a fixing mechanism. A connecting rod 20 is slidably connected inside the connecting handle 18. A handle 21 is slidably connected to the side wall of the connecting rod 20. The connecting rod 20 and the connecting handle 18 are fixed by a seat post clamp 22. The fixing mechanism includes side ears 15 and the connecting handle 18. The side ears 15 are located on one side of the top of the base 1. The opposite sides of the side ears 15 are provided with toothed grooves 16. The connecting handle 18 is provided between the side ears 15. One end of the connecting handle 18 is fixedly connected to a toothed block 19. The side lugs 15 are made of plastic and have a certain deformation capacity; they can be deformed by applying pressure, thus releasing or clamping the toothed block 19. An adjusting bolt 17 is threaded inside the side lug 15. The thread on the side wall of the adjusting bolt 17 is set in two symmetrical sections. The connecting handle 18 is rotatably connected to the middle section of the side wall of the adjusting bolt 17. By rotating the adjusting bolt 17, the two side lugs 15 can move outward or inward respectively, thereby controlling the engagement or disengagement of the toothed block 19 and the toothed groove 16, achieving rapid adjustment of the connecting handle 18. The purpose of the angle is to ensure that the toothed block 19 and the toothed groove 16 match, so that the connection can be stably maintained and the angle of the connecting rod 20 can be kept from shifting when the lock is not released. There are two seat tube clamps 22, which are used to lock the positions of the connecting handle 18 and the grip 21 respectively. The bottom seat tube clamp 22 is located at the splice of the connecting handle 18 and the connecting rod 20, and is used to stabilize the connection position of the two and prevent the connecting rod 20 from shaking during use. The side wall of the connecting rod 20 is provided with a grip 21, which is connected to the connecting rod 20 through a sliding ring, so that its height is adjustable to meet different usage needs. As required, the top seat clip 22 is located at the connection between the sliding ring and the connecting rod 20. The seat clip 22 fixes the position of the handle 21, enhancing the stability and comfort of the equipment during use after adjustment. The seat clip 22 is a readily available technology, and the clamping force is adjusted by rotating the screw, which will not be elaborated on here. During the use of the equipment, when it is necessary to clean sofas, mattresses or carpets, the connecting rod 20 can be removed from the connecting handle 18 to reduce the size of the equipment and make it easier to hold. Then, the injected cleaning fluid can be replaced with foam to clean the product.

[0039] Working principle: When using this equipment to clean the floor, first place the cleaning disc 13 on top of the carpet, and then connect the water outlet pipe to the water inlet pipe 14. At this time, the water will enter the interior of the elbow joint 8 through the pipe, and flow in the water passage inside the elbow joint 8, the mounting frame 7, and the hollow rotating shaft 9, and finally flow out from the middle of the cleaning disc 13. At this time, the motor 5 can be started to drive the drive gear 4 to rotate, which in turn drives the driven gear 10 to rotate synchronously. While the driven gear 10 is rotating, the hollow rotating shaft 9 will rotate inside the mounting frame 7 and the fixing plate 2 3 with the cooperation of the bearing 11, and drive the cleaning disc 13 to rotate on the surface of the floor through the connector 12, and clean the floor with the flowing liquid.

[0040] When using the equipment, to adjust the angle of the connecting rod 20, the operator can rotate the adjusting bolt 17 to move the two side ears 15 to the sides, causing the toothed block 19 and toothed groove 16 to separate, thus releasing the restriction of the side ears 15 on the connecting handle 18. Then, the operator can move the connecting rod 20 to change its angle. After the angle is determined, the operator can rotate the adjusting bolt 17 in the opposite direction to move the side ears 15 relative to each other, re-pressing the connecting handle 18 and causing the toothed block 19 to re-engage with the toothed groove 16, ensuring the stability of the equipment during use. In addition, when it is necessary to adjust the height of the handle 21, the restriction of the seat clamp 22 connected to it can be released, allowing the handle 21 to move outside the connecting rod 20 via the sliding ring. After determining the position, the seat clamp 22 can be re-locked to ensure the stability of the position.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
