Description

Technical Field

[0001] This invention relates to the field of wall drying technology, and more particularly to a multi-angle drying device for walls after painting. Background Technology

[0002] When decorating interiors, there are many styles of wall decoration, but all require painting. After painting, the surface of the wall is quite humid. Existing walls are mainly air-dried after painting, which delays the decoration process to some extent. In some humid urban environments, the paint dries even more slowly. To improve the drying speed of painted walls, various types of drying devices have been launched on the market.

[0003] To reduce dust adhesion to the wall during the drying process, existing drying devices are usually equipped with filters. However, in actual operation, due to the complex environment, a lot of dust accumulates on the filters. To facilitate the next use of the drying device, the dust on the filters needs to be manually cleaned after each drying cycle. Moreover, existing drying devices are usually upright and their angle is not adjustable. When drying different wall locations, the entire drying device needs to be manually adjusted, which is inconvenient to operate.

[0004] To address the aforementioned issues, this application proposes a multi-angle drying device for wall painting. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-angle drying device for wall painting in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multi-angle drying device for wall painting includes a dryer, a filter screen and a ring installed on the dryer, a rotating frame and an adjusting component for adjusting the height of the rotating frame, a movable frame slidably connected inside the rotating frame, and a motor for adjusting the angle of the dryer installed on the movable frame;

[0008] A guide sleeve is fixed on the rotating frame, and an insert tube that is connected to the ring passes through the guide sleeve. A flange two and a crossbeam are fixed at one end of the insert tube away from the dryer, and a flange one that is connected to the ring is fixed at the other end. A spring one is provided between the flange two and the guide sleeve. A motor four is installed in the insert tube through an mounting arm. A brush plate for cleaning the filter screen is installed at one end of the motor four, and a fan blade is installed at the other end.

[0009] A driven arm is mounted on the rotating frame via shaft one, a bracket is fixed on the rotating frame, and a cam that acts on the crossbeam is mounted on the bracket via shaft two.

[0010] The rotating frame is equipped with a power assembly that drives shaft one and shaft two to rotate.

[0011] During the rotation of the driven arm following the shaft, the moving frame is driven to move in the vertical direction through the transmission component.

[0012] Preferably, the bracket has a strip groove for avoiding the cam.

[0013] Preferably, the adjustment assembly includes a column, a screw sleeve and a screw that engages with the screw sleeve are provided inside the column, the screw sleeve rotates relative to the rotating frame through a connecting shaft, and a motor and a base are fixed at the bottom of the column;

[0014] A slider is fixed on the side wall of the column, and the slider passes through a groove opened on both sides of the column.

[0015] Preferably, a second slider is fixed on the outer wall of the movable frame, and the two sides of the rotating frame have second grooves that are adapted to the second slider.

[0016] Preferably, the power assembly includes an active arm mounted on a rotating frame and a motor for driving the active arm to rotate. A toothed plate is fixed to the end of the active arm, and a gear two that meshes with the toothed plate is mounted on the shaft two.

[0017] A toothed block is slidably connected to the rotating frame. A gear is fixed on the shaft and meshes with the toothed block. A buffer block and a spring are provided inside the toothed block.

[0019] Preferably, the toothed block is connected to the rotating frame via a guide groove.

[0020] Preferably, the diameter of one end of the movable pin is greater than the width of the clearance groove.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0022] 1. In this application, after the drying operation of the dryer is completed, the active arm is driven to rotate by motor one, which is divided into two stages. In the first stage, the dryer moves down with the moving frame. In this state, the protruding end of the cam does not act on the insertion tube, that is, the insertion tube is stationary. In the second stage, as the active arm continues to rotate, under the action of the buffer block and spring two, the tooth block, gear one, driven arm and dryer are stationary, while the protruding end of the cam acts on the crossbeam of the insertion tube, so that the insertion tube is inserted into the ring. In this state, motor three is turned on, the brush plate and fan blades rotate. The brush plate cleans the dust on the filter screen, and the rotation of the fan blades can form an airflow, which can discharge the dust out through the insertion tube. Compared with the traditional manual cleaning method, it saves manual operation and is more convenient to use.

[0023] 2. In this application, the dryer is placed inside the movable frame and is rotatably connected to the movable frame. During the drying process, the rotation of the dryer is driven by the motor, which can perform drying operations at different positions, resulting in a wider drying range. The rotating frame is rotatably connected to the screw sleeve through the connecting shaft. During the drying process, the orientation angle of the dryer can be changed by adjusting the position of the rotating frame, without having to rotate the entire drying device, making it more convenient to operate.

Detailed Implementation

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0036] Please see Figure 1-9 The present invention provides a technical solution:

[0037] A multi-angle drying device for wall painting includes a dryer 10 and a filter screen 17 and a ring 45 installed on the dryer 10. The filter screen 17 is used to filter dust and reduce dust from adhering to the paint through the dryer 10. The ring 45 covers the outside of the filter screen 17.

[0038] A multi-angle drying device for wall painting includes a rotating frame 5 and an adjusting component for adjusting the height of the rotating frame 5. A movable frame 9 is slidably connected inside the rotating frame 5. A slider 2 7 is fixed on the outer wall of the movable frame 9. The rotating frame 5 has two grooves 22 that are adapted to the slider 2 7 on both sides. The grooves 22 are vertically elongated. The slider 2 7 is slidably connected to the grooves 22. A motor 3 16 for adjusting the angle of the dryer 10 is installed on the movable frame 9. A rotating shaft is fixed on both sides of the dryer 10 and the rotating shaft is rotatably connected to the movable frame 9. The motor 3 16 is used to drive the rotation of the rotating shaft.

[0039] A guide sleeve 32 is fixed on the rotating frame 5, and an insertion tube 26 passes through the guide sleeve 32. The insertion tube 26 and the guide sleeve 32 are in sliding fit. The outer diameter of the insertion tube 26 is not greater than the inner diameter of the ring 45. The insertion tube 26 can be inserted into the ring 45. One end of the insertion tube 26 away from the dryer 10 is fixed with a second flange 37 and a crossbeam 39, and the other end is fixed with a first flange 36. Both the second flange 37 and the first flange 36 are annular. When the insertion tube 26 is connected to the ring 45, the first flange 36 abuts against the ring 45 to achieve a seal. A rubber ring can be glued on the ring 45 to improve the sealing performance.

[0040] A spring 40 is provided between flange 2 37 and guide sleeve 32. Spring 40 is sleeved on the outside of insertion tube 26. Under the action of spring 40, insertion tube 26 moves away from dryer 10. Motor 4 35 is installed inside insertion tube 26 through mounting arm 34. Mounting arm 34 is fixedly connected to the inner wall of insertion tube 26. One end of motor 4 35 is equipped with brush plate 33 for cleaning filter screen 17, and the other end is equipped with fan blade 38. Brush bristles are installed on brush plate 33. When insertion tube 26 is connected to ring 45, the brush bristles on brush plate 33 contact filter screen 17. During the rotation of motor 4 35, brush plate 33 cleans dust on filter screen 17, while during the rotation of fan blade 38, airflow is formed, which can discharge dust to the outside of insertion tube 26.

[0041] A driven arm 43 is mounted on the rotating frame 5 via shaft 23. Shaft 23 is rotatably connected to the rotating frame 5, and shaft 23 is fixedly connected to the driven arm 43. A bracket 8 is fixed on the rotating frame 5. A cam 27 acting on the crossbeam 39 is mounted on the bracket 8 via shaft 31. Shaft 31 is rotatably connected to the bracket 8 and is vertically distributed. Shaft 31 is fixedly connected to the cam 27. During the rotation of the cam 27 following shaft 31, the protruding end of the cam 27 can abut against the crossbeam 39, causing the crossbeam 39 to drive the insertion tube 26 to move. The bracket 8 has a strip groove 28 to avoid the cam 27. The strip groove 28 is set to avoid the bracket 8 interfering with the movement trajectory of the cam 27, so as to facilitate the normal rotation of the cam 27. The rotating frame 5 is equipped with a power component that drives shaft 23 and shaft 31 to rotate. During the rotation of the driven arm 43 following shaft 23, the moving frame 9 is driven to move in the vertical direction through a transmission component.

[0042] Specifically, such as Figure 1 and Figure 2As shown, the adjustment assembly includes a column 2, a screw sleeve 12 and a screw 13 screwed into the screw sleeve 12. The screw 13 is inserted into the bottom of the screw sleeve 12. The column 2 has a cavity to accommodate the screw sleeve 12. The screw sleeve 12 rotates relative to the rotating frame 5 through a connecting shaft 11. The connecting shaft 11 is fixed to the top of the screw sleeve 12. The rotating frame 5 is rotatably connected to the connecting shaft 11. A second motor 14 and a base 1 are fixed at the bottom of the column 2. The second motor 14 is used to drive the rotation of the screw 13. The base 1 has a cavity to accommodate the second motor 14.

[0043] A slider 4 is fixed on the side wall of the column 2. The slider 4 passes through the sliding grooves 3 opened on both sides of the column 2. The slider 4 and the sliding grooves 3 are in sliding fit. During the rotation of the screw 13 driven by the motor 2 14, the screw sleeve 12 can drive the connecting shaft 11 and the rotating frame 5 to move in the vertical direction.

[0044] Specifically, such as Figure 3 , Figure 4 , Figure 5 , Figure 8 and Figure 9 As shown, the power assembly includes an active arm 20 mounted on a rotating frame 5 and a motor 6 that drives the active arm 20 to rotate. A toothed plate 30 is fixed to the end of the active arm 20. The toothed plate 30 is arc-shaped and is concentric with the output shaft of the motor 6. A gear 29 that meshes with the toothed plate 30 is mounted on a shaft 31. As the toothed plate 30 rotates with the active arm 20, the shaft 31 can drive the cam 27 to rotate under the action of the gear 29 and the toothed plate 30.

[0045] A toothed block 21 is slidably connected to the rotating frame 5. The toothed block 21 is connected to the rotating frame 5 through a guide groove 18, which is distributed on the outer wall of the rotating frame 5. A gear 19 that meshes with the toothed block 21 is fixed on the shaft 23. A buffer block 41 and a spring 46 are provided inside the toothed block 21. The buffer block 41 is slidably connected to the inner wall of the toothed block 21. The spring 46 is located on the side of the buffer block 41 closer to the gear 19. A movable pin 24 is fixed on the buffer block 41 and passes through the toothed block 21. The groove 15 and the clearance groove 25 on the active arm 20 are elongated. The through groove 15 is used to prevent the moving pin 24 from moving so that the moving pin 24 can drive the buffer block 41 to move. The moving pin 24 and the clearance groove 25 are slidably connected. The diameter of the end of the moving pin 24 is larger than the width of the clearance groove 25, which can prevent the moving pin 24 from falling out of the clearance groove 25. During the rotation of the clearance groove 25 with the active arm 20, the inner wall of the clearance groove 25 acts on the moving pin 24.

[0046] The transmission component includes a second movable pin 42 fixed on the movable frame 9. The second movable pin 42 is cylindrical. The driven arm 43 has a second relief groove 44 that is adapted to the second movable pin 42. The second relief groove 44 is radially distributed along the rotation center of the driven arm 43. The second movable pin 42 and the second relief groove 44 are slidably connected. During the rotation of the second relief groove 44 following the driven arm 43, the inner wall of the second relief groove 44 acts on the second movable pin 42, and the second movable pin 42 can drive the movable frame 9 to move in the vertical direction.

[0047] In summary, the embodiment provided Figure 1 This is the unfolded state of the drying device. In this state, the dryer 10 is used to dry the paint on the wall.

[0048] After the drying operation is completed, when it is necessary to clean the filter screen 17 on the dryer 10, turn on the motor 6, and the active arm 20 will rotate. The process is divided into the following two steps:

[0049] Firstly, during the rotation of the active arm 20, under the action of the moving pin 24 and the clearance groove 25, the tooth block 21 moves along the guide groove 18. Under the action of the tooth block 21 and the gear 19, the shaft 23 drives the driven arm 43 to rotate. Under the action of the clearance groove 44 and the moving pin 42, the moving frame 9 and the dryer 10 installed on the moving frame 9 are pulled downward.

[0050] Meanwhile, as the toothed plate 30 rotates with the active arm 20, the shaft 21 drives the cam 27 to rotate under the action of the toothed plate 30 and the gear 29 (in the first process, the protruding end of the cam 27 will not act on the crossbeam 39, so the insertion tube 26 is stationary).

[0051] Secondly, when the toothed block 21 moves to the end of the guide groove 18, as the active arm 20 rotates, the toothed block 21 is stationary, causing the moving pin 24 to drive the buffer block 41 to move against the elastic force of the spring 46 (in the first process, due to the elasticity of the spring 46 itself, the spring 46 does not deform). During this process, the gear 19, shaft 23, and driven arm 43 are all stationary.

[0052] Meanwhile, as the gear plate 30 continues to rotate with the active arm 20, under the action of the gear 29, the shaft 21 drives the protruding end of the cam 27 to abut against the insertion tube 26. The insertion tube 26 moves under force and is inserted into the ring 45. The flange 36 abuts against the ring 45 to form a seal.

[0053] At this time, turn on motor 4 35. The output end of motor 4 35 drives brush plate 33 and fan blade 38 to rotate. Brush plate 33 cleans the dust on filter screen 17, while the rotation of fan blade 38 creates airflow, which can discharge the dust out through tube 26. Compared with the traditional manual cleaning method, it has a higher degree of automation and is more convenient to use.

[0054] The above description of the embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
