Description

Technical Field

[0001] The invention relates to the technical field of dust isolation equipment, and in particular to indoor decoration dust isolation equipment and an isolation method. Background Art

[0002] At present, when decorating a new house, when decorating the wall part, the decoration workers first use lime to level it, and then scrape putty powder. In order to make the wall partially flat, after the putty powder is dried as a whole, it needs to be manually polished with fine sandpaper. In this process, a large amount of material will fall off, which is the common dust we see. Grinding putty powder is also the link in the decoration process that is most likely to produce dust pollution.

[0003] An indoor decoration dust isolation device with application number CN202011580411.4, the air suction component includes a fan arranged at the air inlet position on the installation box; the filter component is located between the air inlet and the air outlet, and the filter component includes a plurality of filter nets arranged in the installation box and a cleaning part arranged on the installation box. There is a gap between the outer side surface of the filter net and the inner wall of the installation box, which is convenient for absorbing the dust generated by the decoration and reducing the impact on the working process.

[0004] However, in actual use, putty dust is usually finer, easily suspended in the air and difficult to settle. The external dust isolation equipment cannot complete the adsorption of dust in the first time, causing the staff to easily inhale the dust. In addition, the density of putty dust is relatively small, and it is easily driven by airflow and has a wide diffusion range. This makes it easy for the staff to drive the dust with them when moving, which will greatly reduce the effectiveness of dust collection. In addition, putty will generate static electricity during grinding, causing putty dust to be easily adsorbed on the wall surface, requiring multiple wipes during cleaning, which increases the difficulty and time of cleaning. When the staff uses grinding equipment to grind the putty, the putty dust is difficult to collect, resulting in difficulty in dust cleaning and greatly reducing the efficiency of putty dust collection.

[0005] Therefore, the present invention proposes indoor decoration dust isolation equipment and isolation method to solve the above problems. Summary of the invention

[0016] The invention discloses an indoor decoration dust isolation method, and the isolation method comprises the following steps: S1: When using the isolation device for putty grinding, hold the hand-held part and press the isolation device on the area to be ground. The protection component retracts into the shell component under the compression of the reset spring, so that the grinding disc fits the area to be ground. Before grinding, the adjuster rotates 30° clockwise from the initial position. The adjuster rotates synchronously with the mounting seat, acting as a negative pressure fan, driving the air flow inside the protection component. The air enters through the air inlet. Under the flow of air, the dust is driven to be discharged through the dust collecting pipe, completing the preliminary isolation of the dust. Grinding is performed through the grinding component. During the grinding process, the dust concentration is monitored in real time through the dust sensor; S2: When the dust concentration is less than the first threshold, it indicates that the dust concentration is not high and the grinding state is maintained; S3: When the dust concentration is greater than the first threshold value but less than the second threshold value, the collected dust is likely to fly again during the dust collection process. At this time, the adjuster is activated again and deflected clockwise to a 45° position, which is consistent with the spoiler, thereby increasing the smoothness of air flow, so that when the air circulates inside the protective component, the turbulence is reduced, and the dust discharge speed is increased. Synchronously, the water spray head is activated to atomize and spray the water inside the water tank, increasing the humidity inside the protective component, so that the dust particles are captured by the water mist and discharged with the air flow, accelerating the dust capture efficiency, and the sprayed water mist is atomized onto the wall to maintain a certain humidity during the grinding process, so that the dust is attached to the water and the dust is reduced. S4: When the dust concentration is greater than the second threshold, it indicates that the dust concentration inside the equipment is high. At this time, the adjuster is uniformly deflected clockwise to 90°. At this time, the adjuster acts as a guide body to guide the air, and the wind drive plate on the adjuster fits the wall. The dust on the wall is brushed by the bristles bonded to the outer wall. At the same time, the electromagnetic locking assembly is actuated, causing the shaft to drive the drive assembly and the protective assembly to rotate synchronously. At this time, the drive assembly acts as a negative pressure fan to drive the internal gas flow, and when the protective assembly rotates, the sealing cover and the wall are used to fit together to complete the scraping and cleaning of the dust at the sealing cover, thereby further improving the efficiency of adsorbing dust on the wall.

[0017] Technical effects and advantages of the present invention: 1. The protective component in the present invention wraps the grinding component to improve the dust isolation ability of the grinding component during grinding. The adjuster rotates synchronously with the mounting seat, acting as a negative pressure fan to drive the air flow inside the protective component. The air enters through the air inlet, and under the flow of air, the dust is driven to be discharged through the dust collecting pipe, thereby completing the preliminary isolation of the dust.

[0018] 2. The adjuster in the present invention can adjust the deflection angle, thereby changing the working state of the adjuster. It can adjust the working state in real time according to the dust concentration during grinding of the grinding component, and cooperate with the atomization of the water spray head to enhance the humidity inside the protective component, so that the dust particles are captured by the water mist and discharged with the airflow, which accelerates the dust capture efficiency. In addition, the humidity inside the protective component is increased, and a certain humidity is maintained during the grinding process, so that the dust is attached to the water, reducing the flying of dust. In conjunction with the use of the driving component, the adjuster can scrape and clean the dust attached to the wall, and can simultaneously realize dust isolation, dust collection and dust cleaning during grinding, greatly improving the dust isolation capacity.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] like Figures 1 to 9 As shown, this embodiment discloses indoor decoration dust isolation equipment, including a shell assembly 10, a protective assembly 20 is slidably assembled inside the shell assembly 10, a grinding assembly 30 is fixed inside the shell assembly 10, a driving assembly 40 is assembled on the grinding assembly 30 through an electromagnetic locking assembly, and the driving assembly 40 is fixedly installed on the inner wall of the protective assembly 20. When in actual use, the protective assembly 20 is assembled inside the shell assembly 10, which can provide protection for the grinding assembly 30 and the driving assembly 40.

[0023] See also Figure 1-Figure 3 and Fig. 9 The protective component 20 includes a moving ring 21 embedded in the shell component 10, and a sealing cover 23 is integrally formed on the outer side of the moving ring 21. An air inlet 24 is provided on the sealing cover 23, and a water spray head 25 is fixedly installed at the air inlet 24. A water storage tank 26 is provided inside the moving ring 21, and the water storage tank 26 is connected to the water spray head 25. A rotating ring 27 is slidably assembled on the side wall of the moving ring 21, and a return spring 28 is fixedly connected between the rotating ring 27 and the inner wall of the shell component 10. When in use, the sealing cover 23 covers the wall surface. By pressing the shell component 10, the return spring 28 can be compressed, so that the protective component 20 retracts into the shell component 10 under the compression of the return spring 28, so that the grinding component 30 is attached to the grinding area. In this way, when the grinding component 30 is grinding, the sealing cover 23 can achieve all-round wrapping of the grinding area, greatly improving the dust isolation ability.

[0024] It should be noted that the air inlet 24 is opened at the upper part of the sealing cover 23, and the sealing cover 23 is trumpet-shaped. Each group of water spray heads 25 is equipped with a solenoid valve. A dust sensor arranged at the inlet of the dust collecting pipe 13 is fixed inside the shell assembly 10, which is convenient for spraying water mist into the sealing cover 23 through the water spray head 25, so that dust particles are captured by the water mist and discharged with the airflow, thereby accelerating the dust capture efficiency, and the dust sensor can monitor the dust concentration in real time.

[0025] See also Fig. 9A motor 31 is fixed inside the grinding assembly 30, a rotating shaft 32 is fixedly installed at the output end of the motor 31, a mounting seat 33 is fixed at the other end of the rotating shaft 32, and a grinding disc 34 is installed inside the mounting seat 33. In actual use, the motor 31 drives the grinding disc 34 on the mounting seat 33 to rotate through the rotating shaft 32, thereby grinding the putty on the wall.

[0026] See also Figure 2-Figure 4 The outer wall of the mounting seat 33 is evenly equipped with an adjuster 50 along the circumferential direction. The adjuster 50 includes a small servo motor fixed inside the mounting seat 33, and the output end of the small servo motor extends out of the outer wall of the mounting seat 33 and is fixed with a mounting shaft, and a wind-driving plate 51 is fixedly sleeved on the outer side of the mounting shaft, and the wind-driving plate 51 is assembled between the mounting seat 33 and the protective component 20. When the small servo motor is working, it can drive the mounting shaft to rotate, thereby driving the wind-driving plate 51 to rotate, and can change the deflection angle of the wind-driving plate 51, thereby changing the working state of the adjuster 50, and can adjust the working state in real time according to the dust concentration during grinding of the grinding component 30, so as to facilitate the diversion and isolation of the dust.

[0027] The plane at the initial position of each group of adjusters 50 is parallel to the grinding surface of the grinding disc 34. At this time, the rotation angle of the adjuster 50 is 0. In actual use, multiple groups of adjusters 50 are combined into a protective cover and laid between the mounting seat 33 and the movable ring 21, which can isolate and protect the interior of the protective component 20 and prevent dust from directly entering.

[0028] After each group of adjusters 50 rotates 45° clockwise, the multiple groups of adjusters 50 and the driving assembly 40 remain consistent, thereby enhancing the wind guiding capacity, accelerating the flow speed of the air, and increasing the dust discharge speed.

[0029] After each group of adjusters 50 rotates 90° clockwise, the plane where the adjusters 50 are located is perpendicular to the grinding surface of the grinding disk 34, and multiple groups of adjusters 50 form an air guide structure. The outer wall of the wind driving plate 51 coincides with the grinding surface of the grinding disk 34. When the wind driving plate 51 rotates, it can scrape and clean the dust adsorbed on the wall after grinding, thereby improving the dust cleaning ability.

[0030] See also Figure 1-Figure 3A polishing shell 11 is integrally formed on the shell assembly 10, a hand-held part 12 is fixed on the polishing shell 11, a dust collecting pipe 13 is integrally formed on the polishing shell 11, a moving ring 21 is slidably assembled in the shell assembly 10, the moving ring 21 extends to the inside of the polishing shell 11 and is integrally formed with a sealing ring 22, and the sealing ring 22 is attached to the inner wall of the polishing shell 11, the moving ring 21 is slidably assembled in the shell assembly 10, which is convenient for the movement of the protective assembly 20, and the sealing ring 22 can ensure the sealing between the shell assembly 10 and the protective assembly 20, and prevent dust from entering the assembly between the two with the flow of air. Therefore, when the polishing assembly 30 is working, it can synchronously drive the adjuster 50 to rotate, and the adjuster 50 acts as a negative pressure fan to drive the air flow inside the protective assembly 20, and the air enters through the air inlet 24. Under the flow of air, the dust is driven to be discharged through the dust collecting pipe 13, thereby completing the preliminary isolation of the dust.

[0031] The size of the adjuster 50 matches the distance from the movable ring 21 to the mounting seat 33. The wind driving plate 51 is a flexible plate. The outer wall of the wind driving plate 51 is bonded with bristles. This ensures that the wind driving plate 51 will not scratch the wall when it is attached to the wall. At the same time, it ensures that the wind driving plate 51 can be attached to the wall, making it convenient for the wind driving plate 51 to scrape and clean the dust attached to the wall, thereby improving the cleanliness of the grinding disc 34 during grinding, and can clean the dust adsorbed on the wall in real time, thereby improving the cleaning efficiency.

[0032] See also Figure 4 and Figure 5 The driving assembly 40 includes a driving seat 41 mounted on the outer wall of the rotating shaft 32 and a fixed ring 45 fixed on the inner wall of the movable ring 21, and the driving seat 41 has a built-in electromagnetic locking assembly that matches the rotating shaft 32. The outer wall of the driving seat 41 is evenly provided with sliding grooves 42 along the circumferential direction, and each group of sliding grooves 42 is opened along the length direction of the driving seat 41. A slider 43 is slidably installed in each group of sliding grooves 42, and a spoiler 44 with the same direction is fixed between each group of sliders 43 and the fixed ring 45. The sliding groove 42 is a rectangular groove, and the slider 43 is a rectangular slider.

[0033] In actual use, when the protective component 20 is retracted into the shell component 10, the fixing ring 45 can move the protective component 20 synchronously, and then drive the slider 43 to move in the slide groove 42 through the spoiler 44, and the drive seat 41 is sleeved on the outside of the rotating shaft 32, and both ends are limited, so the drive seat 41 will not move, and when the electromagnetic locking assembly is not in operation, there is no locking relationship between the rotating shaft 32 and the drive seat 41, so the rotation of the rotating shaft 32 will not drive the drive seat 41 to move, each set of spoilers 44 is an arc-shaped plate, and the inclination angle of each set of spoilers 44 is 45 degrees, which is convenient for the spoilers 44 to guide the air, enhance the air flow inside the protective component 20, and facilitate the flowing air to carry dust and be discharged from the dust collecting pipe 13.

[0034] This embodiment also discloses an indoor decoration dust isolation method, which is implemented by using the indoor decoration dust isolation equipment mentioned above. The isolation method comprises the following steps: S1: When using the isolation device for putty grinding, hold the hand-held part 12 and press the isolation device to the area to be ground. The protective component 20 is compressed by the return spring 28 and retracted into the shell component 10 to expose the grinding disc 34, so that the grinding disc 34 is fitted to the area to be ground. Before grinding, the adjuster 50 is rotated 30° clockwise from the initial position. Since the adjuster 50 rotates synchronously with the mounting seat 33, when the adjuster 50 rotates, it can act as a negative pressure fan, which can drive the air flow inside the protective component 20. Since the sealing cover 23 closes the area to be ground on the wall, and then the grinding is performed through the grinding component 30, Therefore, the grinding dust can be isolated by the sealing cover 23, and the air inlet 24 is set to five groups and all are opened at the upper part of the sealing cover 23, which can prevent the dust from falling and utilize the flow speed of the air when entering from the air inlet 24 to carry the dust after grinding to flow. Under the flow of air, the dust enters the shell component 10 with the air flow and is then discharged through the dust collecting pipe 13, and the spoiler 44 can disturb the internal air and increase the moving path of the air inside the protective component 20, so as to facilitate the gas to carry more dust when flowing, and then complete the preliminary isolation of the dust. During the grinding process, the dust concentration is monitored in real time by the dust sensor; S2: When the dust concentration is less than the first threshold value, it indicates that the dust concentration of the grinding component 30 is not high during the grinding work, so the dust can be isolated by the sealing cover 23 to meet the isolation requirement for preventing dust from escaping, so the grinding state is maintained; S3: When the dust concentration is greater than the first threshold value but less than the second threshold value, it is easy for the collected dust to fly again during the dust collection process. Relying solely on the sealing cover 23 to achieve dust isolation can no longer meet the dust removal requirements of dust flowing with the air. At this time, the adjuster 50 is activated again and deflected clockwise to a 45° position, so that the deflection direction and angle of the adjuster 50 are consistent with the spoiler 44. When the adjuster 50 rotates synchronously with the mounting seat 33, the gas flow pressure is enhanced, thereby increasing the air flow speed, and increasing the dust entrainment per unit time by increasing the air flow speed. The number of spoilers 44 increases the dust discharge efficiency, and the spoiler 44 does not reduce the air flow speed when disturbing the flowing air, so that when the air circulates inside the protective component 20, the turbulence is reduced, and the dust discharge speed is increased. Synchronously, the water spray head 25 operates to atomize and spray the water inside the water storage tank 26, which increases the humidity inside the protective component 20, so that the dust particles are captured by the water mist and discharged with the air flow, which accelerates the dust capture efficiency. Moreover, the sprayed water mist is atomized onto the wall, maintaining a certain humidity during the grinding process, so that the dust is attached to the water and the flying of dust is reduced; S4: When the dust concentration is greater than the second threshold, it indicates that the dust concentration inside the equipment is relatively high. At this time, the adjuster 50 is uniformly deflected clockwise to a 90° position. At this time, the adjuster 50 acts as a guide body and has no turbulent effect on the flowing air. It only guides the air to increase the smoothness of gas flow. At this time, the wind drive plate 51 on the adjuster 50 is attached to the wall surface. When rotating, the dust on the wall is cleaned by the bristles bonded and assembled on the outer wall. Therefore, when the dust concentration is relatively high, it is very easy to clean the dust attached to the wall without having to wipe it multiple times later. In this way, dust isolation, dust collection and dust cleaning can be achieved simultaneously during grinding, which greatly improves the dust isolation capability and prevents dust from escaping. At the same time, the electromagnetic locking assembly is actuated to cause the rotating shaft 32 to drive the driving assembly 40 and the protective assembly 20 to rotate synchronously. At this time, the driving assembly 40 acts as a negative pressure fan to drive the internal gas flow. When the protective assembly 20 rotates, the dust attached to the outer edge of the sealing cover 23 is wiped and scraped off by utilizing the fit between the sealing cover 23 and the wall, and then the dust at the sealing cover 23 is scraped and cleaned through the sealing cover 23, thereby further improving the efficiency of dust adsorption on the wall.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.

S2: When the dust concentration is less than the first threshold, it indicates that the dust concentration is not high and the grinding state is maintained; S3: When the dust concentration is greater than the first threshold value but less than the second threshold value, the collected dust is likely to be re-blown during the dust collection process. At this time, the adjuster (50) is activated again and deflected clockwise to a 45° position, which is consistent with the spoiler (44), thereby increasing the smoothness of air flow, so that when the air circulates inside the protective component (20), the turbulence is reduced, and the dust discharge speed is increased. Synchronously, the water spray head (25) is activated to atomize and spray the water inside the water storage tank (26), thereby increasing the humidity inside the protective component (20), so that the dust particles are captured by the water mist and discharged with the air flow, thereby accelerating the dust capture efficiency. Moreover, the sprayed water mist is atomized onto the wall, maintaining a certain humidity during the grinding process, so that the dust is attached to the water, thereby reducing the flying of the dust. S4: When the dust concentration is greater than the second threshold value, it indicates that the dust concentration inside the device is relatively high. At this time, the adjuster (50) is uniformly deflected clockwise to a 90° position. At this time, the adjuster (50) acts as a guide body to guide the air, and the wind drive plate (51) on the adjuster (50) fits the wall, and the dust on the wall is cleaned by the bristles bonded and assembled on the outer wall. At the same time, the electromagnetic locking component is actuated, causing the shaft (32) to drive the driving component (40) and the protective component (20) to rotate synchronously. At this time, the driving component (40) acts as a negative pressure fan to drive the internal gas flow, and when the protective component (20) rotates, the sealing cover (23) is used to fit the wall to complete the scraping and cleaning of the dust at the sealing cover (23), thereby further improving the efficiency of adsorbing dust on the wall.
