Description

Technical Field

[0001] The utility model relates to the field of denture processing, in particular to a dust suction device for denture processing. Background Technique

[0002] The factory processing part of porcelain teeth mainly includes the following steps: plaster model decoration, wax carving, metal casting - metal crown grinding - glazing - porcelain trimming - glazing - polishing. After the above steps, the factory part of porcelain teeth processing can be completed. Processes such as metal crown grinding, porcelain trimming, and polishing are carried out by workers holding a manual grinding machine to grind the surface of the denture according to the shape of the required denture. Since the denture needs to be fully adapted to the patient's oral cavity during production, therefore, the produced denture needs to be manually finely ground before use to grind the denture into a shape that is fully adapted to the patient's oral cavity.

[0003] For example, the patent document with the publication number CN217668790U discloses a dust suction device for denture processing. When air is discharged from the air outlet, it drives the impeller to rotate. The impeller drives the scraper and the brush to rotate, and the brush cleans the filter plate, which is not only energy-saving and environmentally friendly, but also reduces the possibility of the filter plate being blocked. However, after the scraper and the brush clean the filter plate, with the change of air pressure, dust will continue to adhere to the filter plate, affecting the filtering effect.

[0023] The following further illustrates the present utility model with reference to the accompanying drawings:

[0024] As Figure 1 - Figure 4 shown, a denture processing dust suction device includes a dust suction pipe 100. A filter chamber 102 is provided in the middle of the dust suction pipe 100. A cleaning chamber 101 is provided on the front side of the filter chamber 102. The filter chamber 102 and the cleaning chamber 101 communicate with each other. A cleaning mechanism is provided in the cleaning chamber 101. The cleaning mechanism includes a double-filter plate 201. The double-filter plate 201 is slidably connected to the connection part of the filter chamber 102 and the cleaning chamber 101. The sliding direction of the double-filter plate 201 is the front-rear direction. Filter nets are provided on the front and rear sides of the double-filter plate 201. A brush body 203 is provided inside the cleaning chamber 101. The brush body 203 contacts the double-filter plate 201. A vertical sliding column 202 is fixedly connected to the top surface of the brush body 203. The vertical sliding column 202 is slidably connected to the cleaning chamber 101. An L-shaped column 204 is fixedly connected to the side of the brush body 203 away from the double-filter plate 201. A dust collection box 210 is inserted through the bottom end of the cleaning chamber 101. A one-way door assembly is provided below the cleaning chamber 101. A cleaning power assembly is provided at the top of the vertical sliding column 202. A switching mechanism is provided outside the filter chamber 102.

[0025] The double-filter screen filter plate 201 is used to filter dust. The vertical sliding column 202 keeps the brush body 203 sliding along the double-filter screen filter plate 201, so that the brush body 203 slides downward, pushing the dust accumulated on the double-filter screen filter plate 201 to slide downward. At the same time, the L-shaped column 204 slides downward accordingly. The L-shaped column 204 presses against the door panel 205, opens the door panel 205, and pushes the dust into the lower side of the cleaning chamber 101. The water kettle enters the dust collection box 210.

[0026] The cleaning power assembly includes an electric telescopic rod 209. The bottom end of the electric telescopic rod 209 is fixedly connected to the filter chamber 102, and the top end of the electric telescopic rod 209 is fixedly connected to a cross plate 208. The cross plate 208 is fixedly connected to the vertical sliding column 202.

[0027] The cross plate 208 is used to connect the vertical sliding column 202 and the electric telescopic rod 209. The electric telescopic rod 209 controls the lifting and lowering of the cross plate 208 through its own telescopic movement, and further controls the lifting and lowering of the vertical sliding column 202 and the brush body 203.

[0028] The one-way door assembly includes a door panel 205. One end of the door panel 205 is hinged to the side of the cleaning chamber 101 away from the filter chamber 102. A limit block 207 is provided above the door panel 205. The limit block 207 is fixedly connected to the cleaning chamber 101. A spring piece 206 for keeping the door panel 205 in the closed state is provided on the lower side of the door panel 205.

[0029] The spring piece 206 uses its own elasticity to keep the door panel 205 in the closed state, and the limit block 207 prevents the door panel 205 from turning up.

[0030] The switching mechanism includes a threaded sleeve 301. The threaded sleeve 301 is threadedly connected to a threaded rod 303. Both ends of the threaded rod 303 are rotatably connected to bearing seats 302. The bearing seats 302 are fixedly connected to both ends of the double-filter screen filter plate 201. One end of the threaded rod 303 is fixedly connected to a twisting handle 304.

[0031] The threaded sleeve 301 is used to be threadedly connected to the threaded rod 303. The bearing seats 302 rotatably connect the threaded rod 303. Manually rotating the twisting handle 304 drives the threaded rod 303 to rotate, so that the double-filter screen filter plate 201 slides back and forth to complete the switching of the filter screen, and the exposed filter screen can be manually cleaned.

[0032] A square ring base 401 is provided on the lower side of the suction pipe 100. Both ends of the square ring base 401 are fixedly connected to support plates 402. The top ends of the support plates 402 are fixedly connected to the suction pipe 100.

[0033] The support plates 402 are used to support the device, and the square ring base 401 is used to connect the suction pipe 100 and the support plates 402.

[0034] A negative pressure device 500 is installed at one end of the suction pipe 100 away from the cleaning chamber 101.

[0035] The negative pressure device 500 generates negative pressure for sucking in dust and air.

[0036] Working principle:

[0037] The negative pressure device 500 is started, and the negative pressure device 500 generates negative pressure. The left end of the dust suction pipe 100 begins to inhale dust and air. The air passes through the double-mesh filter plate 201, and the dust adheres to the left side of the double-mesh filter plate 201. As the dust accumulates more, the electric telescopic rod 209 is started, so that the electric telescopic rod 209 drives the horizontal plate 208 to move downward, and the vertical sliding column 202 pushes the brush body 203 to descend. The brush body 203 pushes the accumulated dust to move downward. At the same time, the L-shaped column 204 moves with the brush body 203, and the L-shaped column 204 supports the door panel 205, so that the door panel 205 is opened, and the dust is pushed to the bottom of the cleaning chamber 101. The electric telescopic rod 209 is controlled to extend, and the horizontal plate 208 and the vertical sliding column 202 move upward. The brush body 203 and the L-shaped column 204 also move upward accordingly. The L-shaped column 204 leaves the door panel 205, and the spring sheet 206 pushes the door panel 205 to reset to form a closed door to prevent dust from escaping.

[0038] When the double-mesh filter plate 201 accumulates a lot of dust, the threaded rod 303 is rotated by manually rotating the twist handle 304, and the threaded rod 303, the bearing seat 302 and the double-mesh filter plate 201 are horizontally moved under the threaded connection of the threaded sleeve 301 to remove the filter screen that is full of dirt and facilitate manual cleaning of the filter screen.

[0039] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
