Description

Technical Field

[0001] This utility model relates to the technical field of spittoon deodorizing devices, and in particular to a dental spittoon deodorizing device. Background Technology

[0002] During dental treatment, patients frequently need to spit and rinse their mouths, making dental spittoons an indispensable auxiliary device. Existing dental spittoons mainly consist of a basin, drain outlet, odor preventer, and a few auxiliary structures. Their core functions primarily meet basic needs for waste collection, discharge, and general odor prevention. However, the waste discharge and odor prevention structure has several issues: firstly, its odor-proof sealing is poor, easily allowing foul-smelling gases to backflow from gaps; secondly, filtered debris easily adheres to the filter screen, making manual disassembly and cleaning very troublesome. Therefore, we propose a dental spittoon waste discharge and odor preventer. Utility Model Content

[0003] The main purpose of this invention is to provide a dental spittoon drain and deodorizer, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A dental spittoon waste disposal and odor prevention device includes a filter cylinder, a guide tube connected to the lower end of the filter cylinder, a filter structure movably installed in the filter cylinder, a silicone side seal fixedly installed at the lower port of the guide tube, and a mounting plate fixedly installed on the guide tube. Two mounting plates are provided, and a self-sealing structure is movably installed between the two mounting plates. A lifting ring is movably installed inside the filter cylinder.

[0005] Preferably, the filter structure includes a pull rod that is movably inserted into the bottom of the filter cylinder, a pull ring connected to the lower end of the pull rod, a screw hole opened at the upper end of the pull rod, a spring sleeved on the surface of the pull rod, and a filter screen fixed to the upper end of the pull rod by bolts passing through the fixing ring.

[0006] Preferably, the fixing ring is fixedly installed in the middle of the filter screen, and the bolt is locked in place by screwing it into the screw hole.

[0007] Preferably, the self-sealing structure includes a counterweight block rotatably mounted between two mounting plates via a rotating shaft, a sealing plate connected to the counterweight block, and a sealing groove formed on the sealing plate.

[0008] Preferably, the lower end of the guide tube is embedded in the sealing groove through a silicone edge seal to form a seal, the spring is set on the inner side of the filter cylinder to lift the fixing ring, and the edge of the filter screen is slidably arranged in contact with the inner side of the filter cylinder.

[0009] Compared with the prior art, the present invention has the following beneficial effects: In this invention, the odor preventer, through the combination of a sealing groove and a silicone edge seal, can tightly seal the lower end of the guide pipe without discharging sewage, thus better preventing backflow of odors from the lower pipe. Furthermore, through the designed filter structure, after removing the odor preventer, pulling the pull ring compresses the spring, and then releasing it instantly. At this moment, as the spring quickly rebounds and immediately stops due to the limiting structure pull ring, the debris adhering to the filter screen can be thrown out into the trash can due to inertia. After repeated operations, cleaning can be completed, making the operation simple and quick. Attached Figure Description

[0012] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0013] Example 1: like Figure 1-5 As shown, the dental spittoon waste disposal and odor prevention device includes a filter cylinder 1, a guide tube 2 connected to the lower end of the filter cylinder 1, a filter structure 3 movably installed in the filter cylinder 1, a silicone side seal 4 fixedly installed at the lower end of the guide tube 2, and a mounting plate 7 fixedly installed on the guide tube 2. There are two mounting plates 7, and a self-sealing structure 5 is movably installed between the two mounting plates 7. A lifting ring 6 is movably installed inside the filter cylinder 1. The filter structure 3 includes a pull rod 31 that is movably inserted at the bottom of the filter cylinder 1, a pull ring 32 connected to the lower end of the pull rod 31, a screw hole 33 opened at the upper end of the pull rod 31, a spring 35 sleeved on the surface of the pull rod 31, and a filter screen 36 fixed to the upper end of the pull rod 31 by a bolt 34 passing through a fixing ring 37. Specifically, by pulling the pull ring 32, the pull rod 31 moves downward, causing the fixed ring 37 and filter screen 36 to slide downward. At this time, the spring 35 is compressed. Then, the pull ring 32 is released instantly. Under the spring's rebound force, the fixed ring 37 and filter screen 36 are pushed towards the port of the filter cartridge 1. At this time, the pull ring 32 stops the movement instantly. Through inertia, the debris is thrown out, thus completing one cleaning cycle.

[0014] The retaining ring 37 is fixedly installed in the middle of the filter screen 36, and the bolt 34 is locked in place by screwing it into the screw hole 33; Specifically, bolt 34 can be separated from pull rod 31, thereby allowing disassembly and maintenance of filter screen 36, as well as replacement or maintenance of easily damaged structural components such as spring 35.

[0015] The self-sealing structure 5 includes a counterweight 51 rotatably mounted between two mounting plates 7 via a pivot 54, a sealing plate 52 connected to the counterweight 51, and a sealing groove 53 formed on the sealing plate 52. Specifically, the counterweight 51 can rotate freely between the two mounting plates 7 via the pivot 54. The weight of the counterweight 51 and the pivot 54 as the fulcrum will cause the sealing plate 52 to tilt upward, so that the sealing plate 52 is always under force and sealed at the lower end of the guide tube 2. Furthermore, the sealing groove 53 and the silicone edge seal 4 seal tightly, which better prevents the leakage and backflow of odor from the gaps.

[0016] The lower end of the guide tube 2 is embedded into the sealing groove 53 through the silicone side seal 4 to form a seal. The spring 35 is set on the inner side of the filter cylinder 1 to lift the fixing ring 37. The edge of the filter screen 36 is slidably set to contact the inner side of the filter cylinder 1. Specifically, the inner surface of the filter cylinder 1 is a smooth surface, and the outer arc surface of the filter screen 36 is also a smooth surface. Therefore, the edge of the filter screen 36 can slide on the inner surface of the filter cylinder 1, thereby achieving the effect of instantaneous pop-out through the spring 35.

[0017] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
