Description

Technical Field

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

[0002] Currently, putty sanding is a crucial step in wall decoration, directly affecting the smoothness of subsequent latex paint spraying and the overall quality of the decoration. However, existing putty sanding methods have many drawbacks. Traditional putty sanding mainly relies on manual operation with small hand-held sanding tools, which is not only labor-intensive and inefficient, but also makes it difficult to ensure the smoothness of the wall surface, resulting in unevenness when spraying latex paint and affecting the aesthetics of the decoration. At the same time, a large amount of dust is generated during the sanding process. This dust flies around and seriously pollutes the indoor environment, posing a great threat to the health of construction workers, such as causing respiratory diseases. Although some construction work adopts some simple dust prevention measures, such as laying plastic sheets under the sanding area, the dust prevention effect is limited, and a large amount of dust still escapes into the air. Moreover, cleaning up this scattered putty dust after the decoration is completed is extremely difficult, increasing decoration costs and time. Therefore, developing a wall decoration putty cleaning device that can effectively improve putty sanding efficiency, ensure wall surface smoothness, reduce dust generation, and facilitate cleaning is of great practical significance. Utility Model Content

[0003] In view of the above-mentioned technical problems in related technologies, this utility model provides a putty cleaning device for wall decoration, which can solve the above problems.

[0004] To achieve the above-mentioned technical objectives, the technical solution of this utility model is implemented as follows: A putty cleaning device for wall decoration includes a dust collection bin, a dust collection mechanism, and a dust collection hood. A soft edging is fixedly installed on the front end of the dust collection hood, and a sanding disc is provided on the front end of the dust collection hood. A sleeve is fixedly installed on the rear end of the dust collection hood, and a motor for driving the sanding disc to rotate is installed inside the sleeve. A hinged bracket is welded and fixed to the bottom of the sleeve, and a handle is hinged to the bottom end of the hinged bracket. An interface is opened on the rear end of the dust collection hood, and the interface is connected to the dust collection bin through a pipe. The dust collection mechanism is fixed to the top of the dust collection bin by screws.

[0005] Furthermore, the dust collection mechanism includes a housing, with a partition inside the housing. A motor is fixedly installed on the top of the partition, and the motor shaft of the motor passes through the partition. Fan blades are coaxially connected to the motor shaft. An air outlet is installed on one side of the housing, and an air inlet is installed at the bottom of the housing. A filter cartridge is fastened to the air inlet port.

[0006] Furthermore, the air intake is a cone shape that is wider at the top and narrower at the bottom, and an electronic control switch and a U-shaped handle are fixedly installed on the outside of the top of the housing.

[0007] Furthermore, an internally threaded sleeve is fixedly installed at the bottom of the handle, and an extension rod is connected to the internal thread of the internally threaded sleeve.

[0008] Furthermore, a cover plate is fixedly installed on the end face of the sleeve by screws, and a heat dissipation groove is opened on the surface of the cover plate, with a dustproof net fixedly installed inside the heat dissipation groove.

[0009] Furthermore, a locking screw is provided on the outside of the hinged bracket, which passes through the hinged bracket and the top of the handle, and a nut is threaded to the end of the locking screw.

[0010] The beneficial effects of this utility model are as follows: The device of this application has an extended handle to control the wall putty sanding mechanism to sand the wall surface.

[0015] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0016] like Figs. 1-3 As shown, this utility model discloses a putty cleaning device for wall decoration, including a dust collection bucket 1, a dust collection mechanism 2, and a dust collection hood 8.

A sleeve 5 is fixedly installed on the rear end of the dust collection hood 8, and a motor 10 for driving the sanding disc 9 to rotate is provided inside the sleeve 5. A hinged bracket 7 is welded and fixed to the bottom of the sleeve 5, and a handle 4 is hingedly installed at the bottom end of the hinged bracket 7. A connection is provided on the rear end of the dust collection hood 8. Interface 802 is connected to dust collection bin 1 via pipe 3. The dust collection mechanism 2 is fixed to the top of dust collection bin 1 by screws. The dust collection mechanism 2 includes a housing with a partition inside. A motor 205 is fixedly installed on the top of the partition. The motor shaft of the motor 205 passes through the partition. A fan blade 206 is coaxially connected to the motor shaft of the motor 205. An air outlet 203 is connected to one side of the housing. An air inlet 207 is opened at the bottom of the housing. A filter cartridge 204 is fastened to the port of the air inlet 207.

[0017] Example 1: The grinding disc 9 includes a grinding disc on the surface and a pin sleeve 901 on the back. The motor 10 is fixed to the back of the dust collection cover 8 by bolts, and the motor 10 is also housed inside the sleeve 5. The motor shaft of the motor 10 passes through the dust collection cover 8, is fitted with the pin sleeve 901 and is fastened by screws. The motor 10 leads out a power cord and is connected to the power socket for power supply. The sleeve 5 is fixed to the back of the dust collection hood 8 by bolts. The head end of the handle 4 is snapped into the inside of the hinge bracket 7. The locking screw 701 passes through both the hinge bracket 7 and the head end of the handle 4. The threaded end nut is tightened by tightening the locking screw 701 to limit the angle of the handle 4. An extension rod 402 is added to the bottom of the handle 4 through the internal threaded sleeve 401 to increase the working height range. One end of the pipe 3 is connected to the interface 802, and the other end is connected to the interface on the outer wall surface of the dust collection bin 1. The dust collection mechanism 2 is driven by the motor 205 to rotate the fan blade 206, generating negative pressure suction at the air inlet 207. The airflow passes through the interface 802, pipe 3, filter cartridge 204, and air inlet 207, and is finally discharged from the air outlet 203. That is, the dust generated by the sanding disc 9 sanding the putty wall will enter the dust collection bin 1 with the airflow. The filter cartridge 204 prevents dust from entering the air inlet 207 and the fan blade 205 area. When the suction is insufficient, the dust collection mechanism 2 needs to be disassembled, and the filter cartridge 204 needs to be disassembled to clean the dust adhering to the surface. The motor 205 is connected to the power supply of the power board through the power cord and is controlled to start and stop by the power control switch 201.

[0018] In the preferred technical solution, the air inlet 207 is a cone shape that is wider at the top and narrower at the bottom. The design of the upper part of the air inlet 207 corresponds to the suction area of ​​the fan blade 205. An electric control switch 201 and a U-shaped handle 202 are fixedly installed on the top of the housing. The electric control switch 201 controls the start and stop of the vacuum motor, and the U-shaped handle 202 facilitates the separation of the vacuum mechanism 2 from the dust collection bin 1.

[0019] In the preferred technical solution, an internally threaded sleeve 401 is fixedly installed at the bottom of the handle 4, and an extension rod 402 is connected to the internal thread of the internally threaded sleeve 401. An extension rod 402 is added to the bottom of the handle 4 through the internally threaded sleeve 401 to increase the working height range.

[0020] In the preferred technical solution, a cover plate 6 is fixedly installed on the end face of the sleeve 5 by screws. A heat dissipation groove 601 is opened on the surface of the cover plate 6. A dustproof net is fixedly installed on the inner side of the heat dissipation groove 601. The motor 10 is housed inside the sleeve 5. The cover plate 6 has a heat dissipation groove 601 and a dustproof net. Air circulation dissipates heat while reducing dust contact with the motor 10.

[0021] In the preferred technical solution, a locking screw 701 is provided on the outside of the hinged bracket 7. The locking screw 701 passes through the hinged bracket 7 and the top of the handle 4. A nut is threaded to the end of the locking screw 701. The angle of the handle 4 is limited by tightening the locking screw 701.

[0022] In practical use, both motor 10 and motor 205 are powered on simultaneously, the sanding disc 9 rotates, and negative pressure is generated at interface 802 to adsorb dust. The handle 4 is used to move the sanding disc to fit the putty wall and sand the raised parts of the wall. During the process, the soft edge 801 adapts to fit the wall surface to reduce dust overflow. The dust is transferred to the dust collection bin 1 by the negative pressure airflow. The sanding disc 9 and filter cartridge 204 can be replaced periodically.

[0023] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
