Description

Technical Field

[0001] This utility model relates to the field of pre-filter technology, and more specifically, to a pre-filter for processing residues used in implant restoration abutments. Background Technology

[0002] Implant abutments are dental medical products that securely connect implants to crowns and other superstructures. During the fabrication of implant abutments, a pre-filter is needed to initially filter out processing residues. Traditional pre-filters consist of a filter screen, a housing, and inlet and outlet pipes. The filter screen removes residues from the inlet pipe. However, after prolonged use, residues adhere to the filter screen surface, causing blockage and affecting water flow rate, thus shortening the lifespan of the pre-filter. To address the shortcomings of existing technologies, we propose a pre-filter for processing residues in implant abutments. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, this utility model provides a pre-filter for processing residues on implant restoration abutments, so as to solve the problem that after long-term use, residues adhering to the surface of the filter screen will clog the filter screen and affect the water flow rate, thus affecting the service life of the pre-filter to a certain extent.

[0004] To solve the above technical problems, this utility model provides the following technical solution: a pre-filter for processing residues of implant repair abutments, comprising a shell, an inlet pipe provided above the shell, an outlet pipe provided below the shell, a filter assembly provided inside the shell, and a dredging assembly provided between the shell and the outlet pipe;

[0005] The filter assembly includes a mounting base fixedly connected to the top of the housing. An outer filter screen is detachably mounted on the top of the mounting base via bolts, and the outer filter screen is located in the inner cavity of the housing. An inner filter screen is provided in the inner cavity of the outer filter screen. A top cover is detachably mounted on the top of the outer filter screen via bolts. A motor is fixedly mounted on the inner wall of the top cover. A rotating shaft is fixedly connected to the output end of the motor. A fixing plate is fixedly connected to the outer wall of the rotating shaft. A guide rod is fixedly connected to one outer surface of the fixing plate. A baffle is fixedly connected to the end of the guide rod away from the fixing plate. A clamping plate is slidably connected to the outer wall of the guide rod. A compression spring is fixedly connected to one outer surface of the clamping plate, and the end of the compression spring away from the clamping plate is fixedly connected to the baffle. A cotton towel is placed between the fixing plate and the clamping plate.

[0006] The fixing plate and clamping plate are used to hold the cotton towel, which is used to clean the inner wall of the inner filter screen. The water inlet pipe is fixedly connected to the top of the top cover.

[0007] The fixed plate, clamp, and cotton towel are all in pairs and are arranged in a circular array at equal angles around the central axis of the rotation shaft. The guide rod, baffle, and compression spring are all in four pairs and are symmetrically distributed on the upper and lower sides of the two clamps.

[0008] The unblocking component includes an extension tube fixedly connected to the bottom of the housing. An electric push rod is fixedly installed on the inner wall of the extension tube. A movable slider is fixedly connected to one end of the electric push rod. A circular frame is fixedly connected to one side of the outer surface of the movable slider. A sealing plate is rotatably connected to the right side of the outer surface of the circular frame. A torsion spring is fixedly connected to one side of the outer surface of the sealing plate, and the end of the torsion spring away from the sealing plate is fixedly connected to the circular frame. An electromagnet is fixedly installed at the bottom of the circular frame, and an iron block is fixedly connected to the bottom of the sealing plate.

[0009] The sealing plate is used to close the through hole in the center of the ring frame, and the torsion spring is used to push the sealing plate away from the ring frame.

[0010] The movable slider and the outer wall of the ring frame are in contact with the inner wall of the extension tube, and the water outlet pipe is fixedly connected to the bottom of the extension tube and is located between the movable slider and the ring frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention utilizes a filtration assembly, including an inner filter screen and cotton towels. The inner filter screen filters the water flowing in from the inlet pipe. When the inner filter screen becomes clogged, the motor is activated, driving the rotating shaft to rotate. This causes the two cotton towels to clean the inner wall of the inner filter screen. Residue carried to the outside of the inner filter screen by the cotton towels is then trapped by the outer filter screen. After multiple cleanings, the top cover can be disassembled, the cotton towels removed and replaced, and the new cotton towels placed between the fixing plate and the clamping plate. Under the push of the compression spring, the cotton towels are clamped and fixed. Furthermore, the outer filter screen can be disassembled and cleaned. Using the above structure, the motor drives the cotton towels to clean the inner wall of the inner filter screen, which can prevent residue from clogging the inner filter screen, thereby reducing the impact on the water flow rate, extending the service life of the pre-filter, and improving the flexibility of the device.

[0013] This invention utilizes a drainage component, including a circular frame and a sealing plate. Filtered water from the housing flows into the extension pipe. Under the action of a torsion spring, the sealing plate remains open, allowing water to flow into the outlet pipe. When the water flow rate is not ideal after filtration by the inner and outer filters, an electromagnet is energized, causing the sealing plate to close the circular frame and controlling the electric push rod to retract, drawing water out of the housing. Then, the electromagnet is de-energized, controlling the electric push rod to extend, preventing water from the extension pipe from being squeezed back into the housing. This process repeats, continuously drawing water from the housing to the outlet pipe. Using this structure, the electric push rod drives the circular frame in reciprocating motion, and the electromagnet controls the closing of the sealing plate, which can increase the water flow rate of the pre-filter, reduce the influence of the inner and outer filters on the water flow rate, and improve the practicality of the device.

[0021] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0022] As attached Figure 1 To be continued Figure 5An embodiment of this utility model provides a pre-filter for processing residues of implant restoration abutments, including a housing 1, an inlet pipe 2 provided above the housing 1, an outlet pipe 3 provided below the housing 1, a filter assembly 4 provided inside the housing 1, and a dredging assembly 5 provided between the housing 1 and the outlet pipe 3.

[0023] The filter assembly 4 includes a mounting base 41, which is fixedly connected to the top of the housing 1. An outer filter screen 42 is detachably mounted on the top of the mounting base 41 by bolts, and the outer filter screen 42 is located in the inner cavity of the housing 1. An inner filter screen 43 is provided in the inner cavity of the outer filter screen 42. A top cover 44 is detachably mounted on the top of the outer filter screen 42 by bolts. A motor 45 is fixedly mounted on the inner wall of the top cover 44. A rotating shaft 46 is fixedly connected to the output end of the motor 45. A fixing plate 47 is fixedly connected to the outer wall of the rotating shaft 46. A guide rod 48 is fixedly connected to one outer surface of the fixing plate 47. A baffle 49 is fixedly connected to the end of the guide rod 48 away from the fixing plate 47. A clamping plate 411 is slidably connected to the outer wall of the guide rod 48. A compression spring 412 is fixedly connected to one outer surface of the clamping plate 411, and the end of the compression spring 412 away from the clamping plate 411 is fixedly connected to the baffle 49. A cotton towel 413 is provided between the fixing plate 47 and the clamping plate 411.

[0024] Among them, the fixing plate 47 and the clamping plate 411 are used to hold the cotton towel 413, the cotton towel 413 is used to clean the inner wall of the inner filter screen 43, and the water inlet pipe 2 is fixedly connected to the top of the top cover 44.

[0025] By disassembling the top cover 44, components such as the rotating shaft 46 and the fixing plate 47 can be removed, thereby replacing the cotton towel 413. By applying pressure to the clamping plate 411 through the compression spring 412, the cotton towel 413 can be fixed between the fixing plate 47 and the clamping plate 411.

[0026] Among them, there are two fixing plates 47, two clamping plates 411, and two cotton towels 413, which are distributed in a ring array at equal angles around the central axis of the rotating shaft 46. There are four guide rods 48, four baffles 49, and four compression springs 412, which are symmetrically distributed on the upper and lower sides of the two clamping plates 411 respectively.

[0027] The motor 45 drives the rotating shaft 46 to rotate, which can drive the cotton towel 413 to clean the inner wall of the inner filter screen 43. The outer filter screen 42 can collect the small amount of dirt that leaks out of the inner filter screen 43 during the process of the cotton towel 413 cleaning the inner filter screen 43.

[0028] The unblocking component 5 includes an extension tube 51, which is fixedly connected to the bottom of the housing 1. An electric push rod 52 is fixedly installed on the inner wall of the extension tube 51. A movable slider 53 is fixedly connected to one end of the push rod of the electric push rod 52. A circular frame 54 is fixedly connected to one side of the outer surface of the movable slider 53. A sealing plate 55 is rotatably connected to the right side of the outer surface of the circular frame 54. A torsion spring 56 is fixedly connected to one side of the outer surface of the sealing plate 55. The end of the torsion spring 56 away from the sealing plate 55 is fixedly connected to the circular frame 54. An electromagnet 57 is fixedly installed at the bottom of the circular frame 54. An iron block 58 is fixedly connected to the bottom of the sealing plate 55.

[0029] Among them, the sealing plate 55 is used to close the through hole in the center of the ring frame 54, and the torsion spring 56 is used to push the sealing plate 55 away from the ring frame 54.

[0030] By energizing the electromagnet 57, the electromagnet 57 can attract the iron block 58, causing the sealing plate 55 to fit against the ring frame 54, thus sealing the through hole in the center of the ring frame 54. At this time, the electric push rod 52 retracts, which can drive the ring frame 54 to extract the water from the housing 1.

[0031] Among them, the outer walls of the movable slider 53 and the ring frame 54 are in contact with the inner wall of the extension tube 51, the water outlet pipe 3 is fixedly connected to the bottom of the extension tube 51, and the water outlet pipe 3 is located between the movable slider 53 and the ring frame 54.

[0032] The movable slider 53 can prevent water from flowing into the vicinity of the electric push rod 52. When the electric push rod 52 retracts, it will push the water between the ring frame 54 and the movable slider 53 into the outlet pipe 3.

[0033] The working process of this utility model is as follows:

[0034] First, the water flowing in from the inlet pipe 2 is filtered through the inner filter screen 43. The filtered water then flows into the inner cavity of the housing 1. When the inner filter screen 43 becomes clogged, the motor 45 is started, driving the rotating shaft 46 to rotate. This causes two cotton towels 413 to clean the inner wall of the inner filter screen 43. Residue carried to the outside of the inner filter screen 43 by the cotton towels 413 is then trapped again by the outer filter screen 42. After multiple cleanings, the top cover 44 can be disassembled, the cotton towels 413 removed and replaced, and then the new cotton towels 413 are placed between the fixing plate 47 and the clamping plate 411. Under the pushing force of the compression spring 412, the cotton towels 413 are clamped and fixed. The outer filter screen 42 can be disassembled and cleaned. The filtered water in the housing 1 will flow into the extension pipe 51. Under the action of the torsion spring 56, the sealing plate 55 will remain open. At this time, the water will flow into the outlet pipe 3. When the water flow rate is not ideal under the filtration of the inner filter screen 43 and the outer filter screen 42, the electromagnet 57 is energized, so that the sealing plate 55 closes the ring frame 54 and controls the electric push rod 52 to retract the push rod, drawing the water out of the housing 1. Then the electromagnet 57 is de-energized, and the electric push rod 52 is extended to prevent the water in the extension pipe 51 from being squeezed back into the housing 1. This process is repeated to continuously draw the water in the housing 1 into the outlet pipe 3.
