Description

Technical Field

[0001] This utility model relates to the field of dental prosthesis processing technology, and in particular to a dust-reducing handheld dental polisher. Background Technology

[0002] A handheld dental polisher is a portable polishing tool specifically designed for denture processing and finishing. It is typically operated by dental technicians or dentists and used to finely polish and finish the edges, occlusal surfaces, or surfaces of dentures to ensure comfortable wear and a good fit to the oral cavity. This compact and flexible device is suitable for polishing, finishing, and other finishing processes of dentures and plays an important role in the fabrication and adjustment of dentures.

[0003] Existing handheld denture polishers do not have an effective dust shielding function during use. They often require external dust collection or protective equipment for dust control, which not only increases equipment dependence and usage complexity, but also common shielding structures such as protective covers or transparent glass plates can easily absorb a large amount of dust in a short time, resulting in obstructed vision, difficulty in cleaning, and usually require stopping the machine for cleaning, which seriously affects work continuity and efficiency.

[0004] Therefore, given that the existing handheld denture polishers lack an effective built-in dustproof structure, rely on external equipment for dust control, and often have dust-accumulating components that obstruct vision, are difficult to clean, and require machine shutdown, thus reducing operational efficiency and work continuity, there is an urgent need to design a new type of dust-reducing handheld denture polisher. Utility Model Content

[0005] In order to overcome the problems of existing handheld denture polishers lacking an effective built-in dustproof structure, relying on external equipment for dust control, and the fact that commonly used shielding parts are prone to dust accumulation affecting vision, making cleaning difficult and requiring machine shutdown, thus reducing operating efficiency and work continuity.

[0006] The technical solution of this utility model is as follows: a dust-reducing handheld dental polisher, comprising a housing and a shielding assembly. The shielding assembly is provided on the front side of the outer end of the housing. The shielding assembly includes a rotating ring, an adjusting block, a connecting rod, an arc plate, a glass frame, a slide groove, a slider, a counterweight, a moving plate, a scraper, and a lever. The rotating ring is damped and connected to the front side of the outer end of the housing. The upper end of the rotating ring is connected to the adjusting block. The upper front end of the adjusting block is connected to the connecting rod. The front end of the connecting rod is connected to the arc plate. The glass frame is provided inside the arc plate. A slide groove is provided on the right side of the outer end of the arc plate. A slider is slidably connected inside the slide groove. The right end of the slider is connected to the counterweight. The left end of the slider is connected to the moving plate. The moving plate is arc-shaped. A scraper is connected to the top of the moving plate. The scraper is movably connected to the glass frame. A lever is connected to the rear top of the adjusting block.

[0007] Preferably, by setting up a shielding component, when grinding is required, a lever is moved, which drives the adjusting block to rotate. The adjusting block drives the rotating ring to rotate on the housing, which in turn drives the connecting rod to adjust the angle of the arc plate as needed. After adjustment, grinding can be performed. This design can shield dust and debris without obstructing the view, effectively preventing dust and debris from flying around. When cleaning the glass frame is required, the housing is swung, causing the counterweight block to slide the slider in the groove due to gravity. This, in turn, drives the moving plate to move. The moving plate drives the scraper to remove the dust adsorbed on the glass frame, thus achieving cleaning of the glass frame without stopping the machine. This design can improve work efficiency and prevent dust from obstructing the view.

[0008] Preferably, the outer end of the housing includes an anti-slip sleeve, and the left end of the swivel is connected to an auxiliary block.

[0009] Preferably, the left end of the auxiliary block is connected to a connecting pipe, and the front end of the connecting pipe is connected to a dust collection hood.

[0010] Preferably, the rear end of the connecting tube is connected to a sleeve, which is fitted onto the external vacuum tube.

[0011] Preferably, a motor is connected to the front of the inner side of the housing, and a grinding head is connected to the output end of the motor.

[0012] Preferably, a switch is provided on the top rear side of the housing, and the switch is electrically connected to the motor.

[0013] Preferably, a power cord is connected to the rear end of the housing, and a plug is connected to the end of the power cord away from the housing.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting up a shielding component, the angle of the arc plate can be adjusted by moving the lever before grinding. With the glass frame, dust and debris can be effectively blocked from flying without obstructing the operator's view, improving the cleanliness and safety of the operation. This structure not only reduces the dependence on external dust collection equipment and simplifies the usage process, but also reduces the risk of dust inhalation while maintaining a clear view, improving the working environment and effectively protecting the operator's health. At the same time, it improves the continuity and efficiency of grinding work, and is particularly suitable for fine processing scenarios such as dentures where cleanliness and precision are required.

[0016] 2. When cleaning the glass frame, simply swing the housing and use the counterweight to drive the scraper to automatically remove the attached dust. No need to stop the machine, which significantly improves cleaning efficiency and work continuity. The overall design takes into account both protection and visibility, avoids frequent cleaning that interferes with operation, and effectively improves the continuity and work efficiency of denture grinding operations.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-5This utility model provides an embodiment of a dust-reducing handheld dental polisher, comprising a housing 1 and a shielding assembly. The shielding assembly is provided on the front side of the outer end of the housing 1. The shielding assembly includes a rotating ring 21, an adjusting block 22, a connecting rod 23, an arc plate 24, a glass frame 25, a sliding groove 26, a slider 27, a counterweight 28, a moving plate 29, a scraper 210, and a lever 211. The rotating ring 21 is dampedly connected to the front side of the outer end of the housing 1, and an adjusting block is connected to the upper end of the rotating ring 21. Block 22, the upper front end of the adjusting block 22 is connected to a connecting rod 23, the front end of the connecting rod 23 is connected to an arc plate 24, the arc plate 24 is provided with a glass frame 25 inside, the outer right end of the arc plate 24 is provided with a sliding groove 26, the sliding groove 26 is slidably connected to a slider 27, the right end of the slider 27 is connected to a counterweight block 28, the left end of the slider 27 is connected to a moving plate 29, the moving plate 29 is arc-shaped, the top of the moving plate 29 is connected to a scraper 210, the scraper 210... 10 is movably connected to the glass frame 25. The top rear side of the adjusting block 22 is connected to the lever 211. By setting the shielding component, when grinding is required, the lever 211 is moved, the lever 211 drives the adjusting block 22 to rotate, the adjusting block 22 drives the rotating ring 21 to rotate on the housing 1, and then drives the connecting rod 23 to adjust the angle of the arc plate 24 as needed. After adjustment, grinding is performed. This design can shield dust and debris without obstructing the view, effectively avoiding the problem of dust and debris flying. When the glass frame 25 needs to be cleaned, the housing 1 is swung, so that the counterweight 28 drives the slider 27 to slide in the slide groove 26 due to gravity, which in turn drives the moving plate 29 to move. The moving plate 29 drives the scraper 210 to scrape off the dust adsorbed on the glass frame 25, thereby realizing the cleaning of the glass frame 25 without stopping the machine. This design can improve work efficiency and avoid dust obstructing the view.

[0025] Please see Figures 1-4 In this embodiment, the outer end of the housing 1 includes an anti-slip sleeve 31, and the left end of the rotating ring 21 is connected to an auxiliary block 32. The anti-slip sleeve 31 facilitates gripping of the housing 1 and prevents slipping. The left end of the auxiliary block 32 is connected to a connecting pipe 33, and the front end of the connecting pipe 33 is connected to a dust collection hood 34, which collects dust. The rear end of the connecting pipe 33 is connected to a sleeve 35, which is sleeved with an external vacuum cleaner pipe. The sleeve 35 can be sleeved with an external vacuum cleaner pipe, thereby using an external vacuum cleaner to suck up the dust.

[0026] Please see Figures 2-4In this embodiment, a motor 36 is connected to the front of the interior of the housing 1. A grinding head 37 is connected to the output end of the motor 36. The motor 36 drives the grinding head 37 to rotate, thereby grinding the denture. A switch 38 is provided on the rear top of the housing 1. The switch 38 is electrically connected to the motor 36. The start and stop of the motor 36 can be controlled by the switch 38. A power cord 39 is connected to the rear end of the housing 1. A plug 310 is connected to the end of the power cord 39 away from the housing 1. The plug 310 is inserted into the power supply, and the motor 36 is powered through the power cord 39.

[0027] When working, first connect plug 310 to the power supply. Power will be supplied to motor 36 through power cord 39. After power is supplied, connect the external vacuum cleaner hose to the external vacuum cleaner and then connect it to sleeve 35. Then, move the dial 211. The dial 211 drives the adjusting block 22 to rotate. The adjusting block 22 drives the rotating ring 21 to rotate on the housing 1, which in turn drives the connecting rod 23 to adjust the angle of the arc plate 24 as needed. After adjustment, polishing is performed. This design can block dust and debris without obstructing the view, effectively preventing dust and debris from flying. Turn on switch 38. The motor 36 is started, which drives the grinding head 37 to rotate. The grinding head 37 is used to grind the denture. The grinding dust is sucked into the connecting pipe 33 through the dust collection hood 34, thereby achieving the effect of dust reduction. When a large amount of dust is adsorbed on the glass frame 25, the swing housing 1 is oscillating, which causes the counterweight 28 to slide the slider 27 in the slide groove 26 due to gravity. This, in turn, drives the moving plate 29 to move. The moving plate 29 drives the scraper 210 to scrape off the dust adsorbed on the glass frame 25, thereby achieving cleaning of the glass frame 25 without stopping the machine. This design can improve work efficiency and avoid dust obstructing the view.

[0028] Through the above steps, by setting up the shielding component, when grinding is required, the lever 211 can be moved first. The lever 211 drives the adjusting block 22 to rotate, and the adjusting block 22 further drives the rotating ring 21 to rotate along the housing 1, thereby driving the connecting rod 23 to adjust the angle of the arc plate 24. The operator can flexibly adjust according to actual needs. After the adjustment is completed, the grinding operation can be carried out. This design effectively prevents dust and debris from flying without obstructing the operator's field of vision, avoiding cleaning and safety problems caused by flying debris. When it is necessary to clean the glass frame 25, the housing 1 can be swung, so that the counterweight 28 drives the slider under the action of gravity. 27 slides along the slide groove 26, thereby pushing the moving plate 29 to move. The moving plate 29 then drives the scraper 210 to scrape off the dust adsorbed on the surface of the glass frame 25, realizing a rapid cleaning operation without stopping the machine. This structure not only improves work efficiency and avoids frequent interruptions in operation due to dust obstructing the view, but also significantly improves the working environment and user experience. It solves the problem that existing denture hand-held polishers lack an effective built-in dustproof structure, rely on external equipment for dust control, and that frequently obstructed parts are prone to dust accumulation, affecting the view, making cleaning difficult and requiring machine shutdown, thus reducing operating efficiency and work continuity.
