Description

Technical Field

[0001] This invention relates to the field of oral cavity debris removal equipment technology, and in particular to a filter for oral cavity cleaning. Background Technology

[0002] Currently, during oral treatment, oral cleaning is generally performed, and the residue from the cleaning is rinsed off by the patient and then flushed away in the sink. With the increasing awareness of environmental protection, people have developed oral cleaning filters to collect and process oral residue, thereby reducing the pollution of groundwater by oral residue and allowing for the collection of samples to test and understand the microorganisms in the oral residue, thus assessing the person's health status.

[0003] Existing oral cleaning filters mainly rely on horizontally positioned filter screens to remove debris. This method makes it easy for debris to clog the filter screens, reducing filtration efficiency. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an oral cleaning filter to solve the aforementioned technical problems.

[0005] The technical solution of the present invention is as follows:

[0006] A mouth cleaning filter includes a housing with an inlet tube mounted on it. The inlet tube has an inlet port at its top and its bottom end passing through the housing. A support plate is installed inside the housing. The support plate has a central hole and a hemispherical mesh covering the central hole, the mesh positioned above the support plate. A cylindrical body is mounted on the support plate outside the hemispherical mesh, the top of which is bent inwards to form a first bend. The top of the first bend is higher than the height of the first bend itself. Bottom height; the top of the first bend is provided with a second bend that bends inward, the top height of the second bend is lower than the bottom height of the second bend, the bottom of the second bend forms a discharge port, the bottom of the feed pipe is provided corresponding to the discharge port, and the hemispherical mesh cover is located below the discharge port; the cylinder or the second bend has a mesh structure, and there is a gap between the outer side of the cylinder and the shell; a liquid collection tank is provided below the central hole, and a ceramic filter layer and a high-efficiency activated carbon layer are arranged sequentially from top to bottom in the liquid collection tank.

[0007] Preferably, the diameter of the material discharge port is smaller than the diameter of the hemispherical mesh cover; an annular groove is provided on the support plate at the position between the cylinder and the hemispherical mesh cover.

[0008] Preferably, the hemispherical mesh cover is integrated with the support plate; a lifting device is provided on the bottom surface of the support plate near the outer edge, and the cylinder is fixed inside the housing; an inspection hole is provided on the housing corresponding to the position of the lifting device, and a sealing cover for sealing the inspection hole is detachably connected to the housing.

[0009] Preferably, the lifting device comprises at least two circumferentially arranged electric hydraulic cylinders, and a support block for supporting the electric hydraulic cylinders is fixed inside the housing. A shielding ring for shielding the electric hydraulic cylinder is fixed on the bottom surface of the support block at a position corresponding to the electric hydraulic cylinder. When the support plate is against the cylinder, there is a gap between the shielding ring and the support block. When the electric hydraulic cylinder is retracted, the shielding ring can be located on the support block.

[0010] Preferably, a drainage hood is fixed on the bottom surface of the support plate at the position corresponding to the central hole.

[0011] Preferably, the drainage hood is sealed to the support plate, and in the retracted state of the electric hydraulic cylinder, the bottom end of the drainage hood contacts the ceramic filter layer; a connecting pipe communicating with the inside of the drainage hood is provided on the outside of the drainage hood, a filter screen covering the connecting pipe is provided on the inside of the drainage hood, a flexible hose is connected to the connecting pipe, a water inlet pipe is provided on the housing, and the flexible hose is connected to the water inlet pipe; the cylinder has a mesh structure, and multiple water spray nozzles are circumferentially arranged on the inner wall of the housing corresponding to the position of the cylinder, and an annular water storage chamber communicating with the water spray nozzles is provided on the outside of the housing, and a water inlet connector is provided on the annular water storage chamber.

[0015] Preferably, a drain pipe is installed at the bottom of the shell corresponding to the bottom of the liquid collection tank, and a drain valve is installed on the drain pipe.

[0016] In use, the oral cleaning filter of this invention allows oral cleaning residue to enter the feed pipe through the inlet along with the rinsing liquid. It is then flushed to the discharge port and falls through a hemispherical mesh cover. Finally, the rinsing liquid flows through the central hole to the collection tank, where it passes through a ceramic filter layer to remove solid particles or medication, and then through a high-efficiency activated carbon layer to remove organic impurities or odors. This separates the residue and water for subsequent processing. During residue filtration, the residue is flushed to the side of the hemispherical mesh cover, preventing accumulation and clogging. Furthermore, even when the mesh cover is clogged, affecting filtration efficiency, the rinsing liquid accumulates and flows outwards along the mesh cylinder or the first bend. It then flows downwards through the gap between the outer side of the cylinder and the shell, eventually passing through the outer side of the support plate into the collection tank. During this process, the residue is filtered out by the mesh cylinder or the first bend, effectively solving the problem of low filtration efficiency caused by residue accumulation.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Example, refer to Figure 1 This embodiment is a filter for oral cleaning, including a housing 10. A feed pipe 20 is mounted on the housing, with a feed inlet 30 at its top. The bottom end of the feed pipe passes through the housing and is located inside the housing. A support plate 40 is installed inside the housing. The support plate has a central hole 41 and a hemispherical mesh cover 42 covering the central hole, the hemispherical mesh cover being located above the support plate. A cylindrical body 50 is provided on the support plate outside the hemispherical mesh cover. The top of the cylindrical body is bent inward to form a first bend 51, the top of which is higher than the bottom. A second bend 52 is provided at the top of the first bend, also bending inward. The top height of the second bend is lower than the bottom height of the second bend. The bottom of the second bend forms a discharge port 53. The bottom of the feed pipe is positioned corresponding to the discharge port. The hemispherical mesh cover is located below the discharge port. Generally, the diameter of the discharge port is smaller than the diameter of the hemispherical mesh cover and preferably larger than the diameter of the feed pipe. The cylinder or the second bend has a mesh structure. There is a gap between the outer side of the cylinder and the shell. A liquid collection tank 60 is provided below the central hole. A ceramic filter layer 61 and a high-efficiency activated carbon layer 62 are arranged sequentially from top to bottom in the liquid collection tank. The ceramic filter layer and the high-efficiency activated carbon layer can use existing structures. For example, the high-efficiency activated carbon can be coconut shell activated carbon or modified activated carbon.

[0031] In use, the oral cleaning filter described above allows cleaning residue to enter the feed pipe through the inlet along with the rinsing liquid. It is then flushed to the discharge port and filtered through the hemispherical mesh cover 42. Finally, the rinsing liquid flows through the central hole to the collection tank, where it passes through a ceramic filter layer to remove solid particles or medication, and then through a high-efficiency activated carbon layer to remove organic impurities or odors. This separates the residue from the water for subsequent processing. When filtering residue, it is flushed to the side of the hemispherical mesh cover, preventing accumulation and clogging. Furthermore, even if the mesh cover is clogged, affecting filtration efficiency, the rinsing liquid accumulates and flows outwards along the mesh cylinder or the first bend. It then flows downwards through the gap between the outer side of the cylinder and the shell, eventually passing through the outer side of the support plate into the collection tank. During this process, the residue is filtered out by the mesh cylinder or the first bend, effectively solving the problem of low filtration efficiency caused by residue accumulation.

[0032] In one embodiment, an annular groove 43 is provided on the support plate at the position between the cylinder and the hemispherical mesh cover. In this way, the residue will first accumulate in the annular groove, reducing the contact between the residue and the hemispherical mesh cover or the mesh cylinder, and improving the utilization rate of the hemispherical mesh cover or the mesh cylinder.

[0033] In one embodiment, the hemispherical mesh cover is integrally connected to the support plate; a lifting device is provided on the bottom surface of the support plate near its outer edge; the cylinder is fixed inside the housing. In this embodiment, it is connected to the housing via a circumferentially arranged connecting plate 54. During manufacturing, one end of the connecting plate can be directly welded to the cylinder, and the other end to the housing; an appropriate gap is provided between the outer side of the support plate and the housing to facilitate the vertical movement of the support plate and the falling of the rinsing liquid. See also Figures 2-4 The housing is provided with an inspection hole 11 at the position corresponding to the lifting device to facilitate the maintenance, cleaning or sampling of the filter by medical personnel. Preferably, a sealing cover 80 for sealing the inspection hole is detachably connected to the housing.

[0034] In one embodiment, the lifting device comprises at least two circumferentially arranged electric hydraulic cylinders 70. A support block 71 for supporting the electric hydraulic cylinders is fixed inside the housing. A shielding ring 44 for shielding the electric hydraulic cylinder is fixed to the bottom surface of the support block at a position corresponding to the electric hydraulic cylinder. When the support plate abuts against the cylinder, there is a gap between the shielding ring and the support block. When the electric hydraulic cylinder is retracted, the shielding ring can be positioned on the support block. This structure allows the electric hydraulic cylinder to retract and move the support plate downwards until the shielding ring is positioned on the support block when cleaning residue after filter use. This difference in distance between the support plate and the cylinder facilitates filter cleaning or sampling by medical personnel. In a preferred embodiment, a drainage hood 45 is fixed on the bottom surface of the support plate at the position corresponding to the central hole; the drainage hood is sealed to the support plate, generally by welding. When the electric hydraulic cylinder is retracted, the bottom end of the drainage hood contacts the ceramic filter layer. During manufacturing, the drainage hood can be made using spring sheets, so that the bottom end of the drainage hood can rest against the ceramic filter layer, and the edges of the drainage hood are less prone to leakage; see also Figure 5 and Figure 2 The outer side of the drainage hood is provided with a connecting pipe 46 communicating with the inside of the drainage hood. The inner side of the drainage hood is provided with a filter screen 47 covering the connecting pipe. A flexible hose 48 is connected to the connecting pipe. A water inlet pipe 15 is provided on the housing. The flexible hose is connected to the water inlet pipe. The cylinder has a mesh structure. Multiple water spray nozzles 16 are arranged circumferentially on the inner wall of the housing corresponding to the position of the cylinder. An annular water storage chamber 17 communicating with the water spray nozzles is provided on the outer side of the housing. A water inlet connector 18 is provided on the annular water storage chamber. The bottom end of the inspection hole is flush with the top end of the ceramic filter element layer. When cleaning residue after filter use, this structure allows the electric hydraulic cylinder to retract, enabling the bottom of the drain hood to contact the ceramic filter element layer. Water is supplied to the inside of the drain hood and the annular water storage chamber through the inlet pipe and inlet connector. Water inside the drain pipe diffuses towards the support plate through the hemispherical mesh cover, and water sprayed from the nozzle diffuses towards the support plate through the cylinder, ultimately flushing the residue on the support plate out through the inspection hole. During this process, the hemispherical mesh cover and the mesh cylinder are reversed, making it less likely for residue to adhere, thus facilitating subsequent use; see also Figure 2 and Figure 6 To prevent liquid flushed out through the inspection hole from directly flowing down the shell and contaminating it, a water receiving plate 19 is detachably connected to the outer wall of the shell at the position corresponding to the ceramic filter element layer.

[0035] As a variation, the cylinder is not designed as a mesh; instead, the first bend is designed as a mesh, and the water nozzle is positioned corresponding to the first bend to achieve the same function. When the first bend is designed as a mesh, the second bend acts as a barrier to the residue, preventing it from moving upwards or inwards.

[0036] In actual manufacturing, the housing is preferably provided with an exhaust hole 12. Of course, the exhaust hole can also be used as an observation hole or a sampling hole, which is well known to those skilled in the art and is not specifically limited here.

[0037] To facilitate the drainage of water from the collection tank, a drain pipe 13 is installed at the bottom of the housing corresponding to the bottom of the collection tank, and a drain valve 14 is installed on the drain pipe. When water needs to be drained from the collection tank, simply open the drain valve. In actual use, a small water pump can also be installed in the collection tank and connected to the drain pipe. A bypass pipe can be installed on the drain pipe to lead water to the feed inlet, water inlet pipe, or water inlet connector for reuse.

[0038] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
