Description

Technical Field

[0001] This utility model relates to the technical field of wall decoration equipment, specifically a putty cleaning device for wall decoration. Background Technology

[0002] Putty application is a common step in wall decoration. However, when it is necessary to renovate, modify, or treat wall defects, the original putty layer needs to be removed.

[0003] When using a scraper to remove putty, workers need to hold the scraper and use considerable force to scrape the putty off the wall. This method is not only labor-intensive but also inefficient, and prolonged operation can easily lead to arm fatigue. Using sandpaper to sand the putty generates a large amount of putty dust during the sanding process, which will permeate the air. Therefore, a putty cleaning device for wall decoration is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a putty cleaning device for wall decoration, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a putty cleaning device for wall decoration, comprising a housing, a connecting plate provided on the inner side of the housing, and a plurality of brush bristles and scrapers fixed on one side of the connecting plate, wherein the brush bristles and scrapers are used to clean putty from the wall surface;

[0006] A water spray assembly is provided on one side of the connecting plate, and a moving assembly is provided on one side of the water spray assembly;

[0007] The water spray assembly includes a connecting frame, a turntable, and a motor, with a rotating shaft fixed to the output shaft end of the motor.

[0008] The connecting frame has a water storage tank inside, and the rotating shaft has a water inlet hole on the outside that communicates with the water storage tank.

[0009] Several water spray holes are provided on one side of the turntable, and water delivery grooves are provided on the inner side of both the turntable and the rotating shaft.

[0010] Preferably, the above-mentioned water inlet holes are of several kinds, the outer side of the rotating shaft is rotatably connected to one side of the connecting frame through a sealed bearing, and one side of the connecting plate is provided with several first through holes, which are used to allow water sprayed from the spray holes to pass through.

[0011] Preferably, the water supply tank is connected to the water inlet and the water spray hole respectively, and one side of the turntable is fixed to the center of one end of the rotating shaft.

[0012] Preferably, the connecting frame and the motor are both fixed to the inner wall of the housing, and a heat dissipation hole is provided on one side of the housing, located on the side of the motor.

[0013] Preferably, as described above, a water pipe connected to a water storage tank is fixed on one side of the connecting frame, a water tank is provided on one side of the water pipe, a water pump is installed inside the water tank, and the water outlet of the water pump is connected to the water inlet of the water pipe.

[0014] Preferably, the movable component includes a fixed ring, the inner wall of which has a plurality of ball sockets, and a ball is attached to the inner side of each ball socket.

[0015] Preferably, as described above, a cover plate is bolted to one side of the fixing ring, and a limiting ring fitted onto the outer side of the sphere is fixed to the inner wall of the cover plate. A second through hole is provided on one side of the limiting ring, and the sphere is adapted to the inner side of the second through hole.

[0016] The retaining ring is fixed to one side of the housing.

[0017] Preferably, the lowest point of the inner wall of the housing is connected to a flexible hose, one end of which is connected to a vacuum cleaner, a handle is installed on the back of the housing, and the connecting plate is fixed to one side of the turntable by bolts.

[0018] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects:

[0019] 1. Water from the tank is pumped to the spray nozzles of the turntable and sprayed out. At the same time, the motor drives the rotating shaft to rotate, which not only drives the turntable to spray water, but also drives the connecting plate to rotate. This causes the brush and scraper on one side of the connecting plate to form a coordinated action of "rubbing first and then scraping". During the cleaning process, the water spray can suppress the flying of putty dust. The turntable drives the brush and scraper to rotate, which can evenly clean the wall surface and reduce the amount of manual work.

[0020] Second, when the worker pushes the handle to move the housing, the ball rotates flexibly within the socket and rolls in contact with the wall surface. This design transforms sliding friction into rolling friction, greatly reducing the friction between the housing and the wall during movement. This allows workers to adjust the device's position on the wall more easily and effortlessly, facilitating putty cleaning operations in different areas of the wall. Attached Figure Description

[0030] Example

[0031] Please see Figure 1-5This utility model provides a technical solution: a putty cleaning device for wall decoration, including a housing 1, a connecting plate 3 on the inner side of the housing 1, and a plurality of brush bristles 5 and scrapers 7 fixed on one side of the connecting plate 3. The brush bristles 5 can be made of plastic, and the scrapers 7 can be made of plastic or metal. The brush bristles 5 and scrapers 7 are used to clean the putty on the wall surface. When cleaning the putty, the brush bristles 5 first come into contact with the wall, followed by the scrapers 7 and the ball 93. The brush bristles 5 and scrapers 7 on the connecting plate 3 come into contact with the putty on the wall surface for scraping and brushing. A water spraying component 6 is provided on one side of the connecting plate 3, and a moving component 9 is provided on one side of the water spraying component 6. Before cleaning the putty on the wall, the putty surface is pre-wetted by spraying water.

[0032] The water spray assembly 6 includes a connecting frame 63, a turntable 69, and a motor 611. A rotating shaft 610 is fixed to the output shaft end of the motor 611. A water storage tank 64 is provided inside the connecting frame 63, and a water inlet 65 communicating with the water storage tank 64 is provided on the outside of the rotating shaft 610. Several water spray holes 66 are provided on one side of the turntable 69, and water delivery channels 67 are provided on the inner sides of both the turntable 69 and the rotating shaft 610. During the cleaning process, the water spray assembly 6 is activated: the water pump 62 in the water tank 10 pumps water into the water storage tank 64 of the connecting frame 63 through the water pipe 61.

[0033] There are several water inlet holes 65. The outer side of the rotating shaft 610 is rotatably connected to one side of the connecting frame 63 through a sealed bearing. Sealing rings are also fixed on both sides of the inner wall of the connecting frame 63. The sealing rings are in contact with the rotating shaft 610 to prevent water leakage. Several first through holes are opened on one side of the connecting plate 3. The first through holes are used to allow water sprayed from the spray hole 66 to pass through. The water supply tank 67 is connected to the water inlet holes 65 and the spray hole 66 respectively. One side of the turntable 69 is fixed to the center of one end of the rotating shaft 610.

[0034] Both the connecting frame 63 and the motor 611 are fixed to the inner wall of the housing 1. A heat dissipation hole is opened on one side of the housing 1, located on the side of the motor 611. A water pipe 61 connected to the water storage tank 64 is fixed on one side of the connecting frame 63. A water tank 10 is provided on one side of the water pipe 61. A water pump 62 is installed inside the water tank 10. The water outlet of the water pump 62 is connected to the water inlet of the water pipe 61. The rotation of the motor 611 drives the turntable 69 and the connecting plate 3 to rotate together, making the water spraying more even. The sprayed water is evenly sprayed onto the wall surface through the first through hole on the connecting plate 3, wetting the putty and making it easier for the brush 5 and scraper 7 to clean.

[0035] The movable component 9 includes a fixing ring 91. The inner wall of the fixing ring 91 has several ball sockets 94, and a ball 93, made of metal, is ball-jointed inside each ball socket 94. A cover plate 92 is bolted to one side of the fixing ring 91. The cover plate 92 is periodically removed for lubrication and maintenance of the ball 93. A limiting ring, fitted onto the outside of the ball 93, is fixed to the inner wall of the cover plate 92. A second through hole is provided on one side of the limiting ring, and the ball 93 fits into the inner side of the second through hole. The fixing ring 91 is fixed to one side of the housing 1. The fixing ring 91 contacts the wall through the ball 93 within the ball sockets 94. The limiting ring on the cover plate 92 restricts the position of the ball 93, reducing friction during device movement. The entire device efficiently cleans wall putty through the combined action of water spraying, brushing, and vacuuming.

[0036] A flexible hose 8 is connected to the lowest point of the inner wall of the housing 1. A guide channel (not shown in the figure) is set inside the housing 1. One end of the flexible hose 8 is connected to a vacuum cleaner 2, which is a wet and dry vacuum cleaner. A handle 4 is installed on the back of the housing 1. The worker grabs the handle 4 and moves the housing 1 so that one side of the housing 1 touches the wall, so that the brush bristles 5 and scraper 7 come into contact with the putty on the wall surface. The connecting plate 3 is fixed to one side of the turntable 69 by bolts. The connecting plate 3 can be replaced by removing the bolts. The lengths of the water pipe 61 and the flexible hose 8 can be set according to actual needs.

[0037] The height of the sphere 93 protruding from the side of the shell 1 is 3-7mm, the height of the scraper 7 protruding is 3-6mm, the height of the bristles 5 protruding is 5-9mm when not under pressure, and can reach 2-5mm after elastic deformation under pressure. The working surface of the scraper 7 forms an angle of 15°-30° with the normal direction of the wall (not shown in the figure), and the back of the scraper 7 forms a back angle of 5°-10° with the tangent direction of the wall (not shown in the figure).

[0038] In this embodiment, the vacuum cleaner 2 is a KM-A100 model manufactured by Shanghai Kemei Machinery Equipment Co., Ltd. Since the structure and operating principle of this model of vacuum cleaner 2 are existing technologies, its structure and operating principle will not be described in detail here.

[0039] Working principle: The worker grabs the handle 4 installed on the back of the housing 1 and moves the housing 1 to a suitable position so that one side of the housing 1 is against the wall side, ensuring that the brush bristles 5 and scraper 7 fixed on the connecting plate 3 are in contact with the putty on the wall surface. At the same time, the various components in the device are started, including the motor 611, water pump 62 and vacuum cleaner 2, etc.

[0040] The water pump 62 installed inside the water tank 10 starts, pumping water from the tank 10 through the outlet into the connected water pipe 61. The water pipe 61 delivers the water to the water storage tank 64 inside the connecting frame 63. The rotating shaft 610, fixed at the output shaft end of the motor 611, begins to rotate. Since there are several water inlets 65 on the outside of the rotating shaft 610 that communicate with the water storage tank 64, the water in the water storage tank 64 enters the water delivery channel 67 inside the rotating shaft 610 through the water inlets 65. One side of the turntable 69 is fixed to the axis of one end of the rotating shaft 610, and the turntable 69 and the water delivery channel 67 inside the rotating shaft 610 are connected. Water enters several spray holes 66 on one side of the turntable 69 through the water delivery channel 67, and finally sprays out from the spray holes 66. The water sprayed from the spray holes 66 can pass through and spray onto the putty on the wall surface.

[0041] The rotation of turntable 69 drives the connecting plate 3 to rotate, which in turn causes several brushes 5 and scrapers 7 fixed on one side of the connecting plate 3 to rotate. The brushes 5 perform preliminary cleaning of the putty on the wall surface through rotational friction, while the scrapers 7 further scrape the putty off the wall surface. The two work together to achieve effective cleaning of the putty on the wall surface.

[0042] When the worker pushes the handle 4 to move the housing 1, the ball 93 can rotate flexibly in the ball socket 94. At the same time, it will not detach from the fixing ring 91 under the restriction of the limiting ring and the second through hole. The ball 93 rolls in contact with the wall surface, reducing the friction between the housing 1 and the wall when it moves. This allows the worker to adjust the position of the device more easily, ensuring that the putty in different areas of the wall can be effectively cleaned. As the cleaning operation proceeds, the wastewater generated by wetting the putty and the putty residue swept off by the brush bristles 5 and scraped off by the scraper 7 will enter the housing 1 under the action of the vacuum cleaner 2. Since the lowest point of the inner wall of the housing 1 is connected to the hose 8, the vacuum cleaner 2 is started at this time. The vacuum cleaner 2 generates negative pressure suction, which sucks the wastewater and putty residue in the housing 1 into the vacuum cleaner 2 through the hose 8, completing the collection of wastewater and residue, avoiding secondary pollution, and keeping the working environment clean.

[0043] In summary, the water in the water tank 10 is pumped by the water pump 62 to the spray nozzle 66 of the turntable 69 and sprayed out. At the same time, when the motor 611 drives the rotating shaft 610 to rotate, it not only drives the turntable 69 to spray water, but also drives the connecting plate 3 to rotate. This causes the brush bristles 5 and scraper 7 on one side of the connecting plate 3 to form a coordinated action of "rubbing first and then scraping". During the cleaning process, the spraying of water can suppress the flying of putty dust. The turntable 69 drives the brush bristles 5 and scraper 7 to rotate, which can evenly clean the wall surface and reduce the workload of manual operation.

[0044] When the worker pushes the handle 4 to move the housing 1, the ball 93 rotates flexibly within the ball socket 94 and rolls into contact with the wall surface. This design transforms sliding friction into rolling friction, greatly reducing the friction between the housing 1 and the wall when it moves. This allows the worker to adjust the position of the device on the wall more easily and effortlessly, facilitating putty cleaning operations in different areas of the wall.

In particular, the features described in the various embodiments and / or claims of this utility model can be combined or combined in various ways without departing from the spirit and teachings of this utility model.
