[0034] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0035] Example 1:

[0036] like Figure 1-6 As shown, an oral cleaning device for clinical examination in the oral department of the present invention comprises a cylindrical shell 1, wherein a plurality of cleaning components and a washing component are distributed on the inner circumference of the cylindrical shell 1, and a through hole is opened at the lower end of the cylindrical shell 1;

[0037] The cleaning assembly includes a strip rod 2 that slides horizontally in the cylindrical shell 1. A strip groove is provided in the strip rod 2. A slider 21 is provided for sliding in the strip groove. The lower end of the slider 21 is connected to a connecting rod 22. A scaler 23 is installed at the lower end of the connecting rod 22. A mounting block 24 is fixed to the side of the slider 21 away from the middle of the cylindrical shell 1. Two fixing plates 25 are fixed in the cylindrical shell 1, respectively located on the front and rear sides of the strip rod 2. The fixing plate 25 has an inclined guide groove 251. The mounting block 24 is fixed with a guide block 241 located in the guide groove 251. The upper end of the strip rod 2 is connected to a pusher.

[0038] The cleaning assembly includes a water pipe 3 installed in the cylindrical shell 1 , the lower end of the water pipe 3 is connected to a spray head 31 facing the middle of the cylindrical shell 1 , and the upper end of the water pipe 3 is connected to a connector 32 .

[0039] The pusher includes a connecting plate 201 fixed to the upper end of the strip rod 2, the upper end of the connecting plate 201 is connected to a push rod 202, the cylindrical shell 1 is provided with a slide groove 203 matching the push rod 202, and the upper end of the push rod 202 is fixed with a push block 204.

[0040] The connecting plate 201 is provided with a sliding hole, and the lower end of the push rod 202 slides into the sliding hole. A positioning plate 205 is fixed in the middle of the push rod 202. A first spring 206 is provided between the lower side of the positioning plate 205 and the connecting plate 201. Positioning blocks 207 are fixed on both sides of the positioning plate 205. Two groups of positioning holes 208 matching the positioning blocks 207 are provided on the upper wall of the cylindrical shell 1. The two groups of positioning holes 208 are respectively located at the two ends of the slide groove 203.

[0041] The scaler 23 is generally divided into sickle-shaped scalers and hoe-shaped scalers;

[0042] The sickle-shaped scaler is one of the most commonly used manual scalers. Its working end is sickle-shaped and has different angles and models to meet the cleaning needs of different tooth surfaces and parts. It uses the sharp edge of the instrument to separate dental plaque and tartar from the tooth surface through scraping action. It is suitable for all tooth surfaces, especially the buccal and lingual surfaces of the front and back teeth, and has a good cleaning effect on some small tartar and pigmentation.

[0043] The working end of the hoe-shaped scaler is similar to a hoe, with a wider shape and a relatively blunt blade. It mainly relies on the pushing and scraping action of the instrument to remove larger pieces of tartar. It is often used on the proximal and occlusal surfaces of the posterior teeth and can quickly remove large areas of tartar.

[0044] In the initial state, different types of scalers 23 are mounted at the lower ends of the connecting rods 22 and are all located within the cylindrical housing 1. The push rod 202 and the push block 204 are located on the side of the chute 203 away from the center of the cylindrical housing 1. At this time, under the elastic force of the first spring 206, the positioning block 207 on the positioning plate 205 is located in a group of positioning holes 208 of the chute 203, fixing the position of the push block 204 and maintaining this state.

[0045] When the operator cleans the patient's oral cavity, the operator holds the cylindrical shell 1 and selects the corresponding scaler 23 to clean the patient's teeth. That is, the operator presses the corresponding push block 204 downward to make the push rod 202 slide downward in the slide hole, and the positioning plate 205 moves downward, so that the positioning block 207 leaves the positioning hole. Then the operator slides the push block 204 to move toward the middle of the cylindrical shell 1. The push block 204 drives the strip rod 2 to move toward the middle of the cylindrical shell 1 through the push rod 202. During the movement of the strip rod 2, the guide block 241 on the mounting block 24 moves downward along the guide groove 251, driving the slider 21 in the strip The rod 2 moves downward in the strip groove, and the scaler 23 moves downward and extends out of the cylindrical shell 1 through the connecting rod 22, so that the corresponding scaler 23 is extended out of the cylindrical shell 1. After the push rod 204 moves to the end of the slide groove 203, the strip rod 2 and the scaler 23 are all located in the center of the cylindrical shell 1, and the positioning block 207 is aligned with the other set of positioning holes 208. After the operator releases the push block 204, the positioning block 207 enters the positioning hole 208 under the elastic force of the first spring 206, and the strip rod 2 and the scaler 23 are fixed. The operator can then use the scaler 23 to clean the patient's teeth.

[0046] When replacing a different scaler 23, just reverse the above steps to retract the scaler 23 into the cylindrical shell 1, and then repeat the above steps to extend the corresponding scaler 23 out of the cylindrical shell 1.

[0047] With this design, the operator can quickly change different scalers 23 to clean different parts of the teeth, making it more convenient to use.

[0048] In actual use, the connector 32 can be connected to an external water supply mechanism. The water supply mechanism is composed of a conventional tank body storing cleaning liquid and a pump body. The water inlet end of the pump body is connected to the tank body, and the water outlet end of the pump body is connected to a hose. The hose is connected to the connector 32. The cleaning liquid can be continuously transported to the connector 32 through the pump body, and the cleaning liquid nozzle 31 sprays it out. Therefore, the nozzle 31 can be used to rinse the patient's teeth.

[0049] When using the scaler 23 to clean teeth, the nozzle 31 can also be used to assist in separating dental plaque and calculus from the tooth surface.

[0050] A sleeve 221 matching the scaler 23 is fixed to the lower end of the connecting rod 22. A threaded through hole is provided in the middle of the sleeve 221. A fixing bolt 222 is threadedly connected to the threaded through hole. The scaler 23 is provided with a fixing hole matching the fixing bolt 222.

[0051] The fixing bolt 222 passes through the fixing hole of the scaler 23 and is threadedly connected to the threaded through hole, so that the scaler 23 can be installed on the lower side of the connecting rod 22. This makes it easy to disassemble and install the scaler 23, and the scaler 23 can be removed after use and disinfected separately.

[0052] The water pipe 3 consists of a fixed pipe 301 and a movable pipe 302. The fixed pipe 301 is fixed to the upper end of the cylindrical shell 1 and is connected to the connector 32. The movable pipe 302 slides inside the fixed pipe 301, and its lower end penetrates the cylindrical shell 1 and is connected to the nozzle 31.

[0053] A movable groove 33 is provided on the lower side of the cylindrical shell 1 , and a toggle block 34 is provided in the movable groove 33 for damping sliding. The toggle block 34 is connected to the movable tube 302 .

[0054] With this design, the operator can slide the toggle block 34 in the movable groove 33 to drive the movable tube 302 to slide in the fixed tube 301, so as to realize the up and down movement of the nozzle 31. After the nozzle 31 is away from the lower end of the cylindrical shell 1, it can easily enter the patient's mouth to clean the patient's teeth, which is more convenient to use.

[0055] After using the scaler 23, the cleaning liquid sprayed from the nozzle 31 can be used to rinse the scaler 23 to prevent dirt from being attached to the scaler 23.

[0056] The toggle block 34 slides in the movable groove 33 with damping, that is, there is a certain resistance between the toggle block 34 and the movable groove 33, and a certain external force needs to be applied to make the toggle block 34 slide in the movable groove 33, and the toggle block 34 itself will not move.

[0057] Rubber pads are provided on both sides of the slide groove 203 and the movable groove 33; the rubber pads can block the slide groove 203 and the movable groove 33 to prevent external impurities from entering the interior of the cylindrical shell 1 through the slide groove 203 and the movable groove 33. Since the rubber pads can be deformed, when the push rod 202 slides in the slide groove 203, the rubber pads can be forced to deform, and the push rod 202 can slide normally in the slide groove 203. Similarly, the toggle block 34 can slide normally in the movable groove 33.

[0058] A rectangular shell 35 is connected to the middle of the fixed tube 301. A blocking block 351 is slidably provided inside the rectangular shell 35. A second spring 352 is provided between the blocking block 351 on one side close to the middle of the cylindrical shell 1 and the side wall of the rectangular shell 35. A sliding rod 353 is fixed to the other side of the blocking block 351. The sliding rod 353 passes through the cylindrical shell 1 and is connected to a pressing block 354.

[0059] In the initial state, the elastic force of the second spring 352 can make the blocking block 351 be located at the fixed tube 301, blocking the fixed tube 301. The external liquid supply mechanism supplies cleaning liquid to the fixed tube 301. At this time, the cleaning liquid cannot flow downward to the nozzle 31. During use, the operator can press the pressing block 354 to drive the blocking block 351 to slide via the sliding rod 353. The blocking block 351 can gradually move away from the fixed tube 301, that is, the cleaning liquid can flow downward to the nozzle 31 through the fixed tube 301.

[0060] With this design, the operator can manually control whether the cleaning fluid needs to be used and control the flow rate of the cleaning fluid.

[0061] A rubber blocking ring 11 is detachably connected to the through hole; the rubber blocking ring 11 can seal the through hole at the lower end of the cylindrical shell 1 to prevent impurities from entering the cylindrical shell 1. When the scaler 23 extends downward from the cylindrical shell 1, the rubber blocking ring 11 can be deformed to expose the through hole for the scaler 23 to pass through.

[0062] Example 2:

[0063] like Figure 7-9 As shown, the toggle block 34 is annular and is sleeved on the outside of the cylindrical shell 1. An annular groove 4 is formed on the inside of the toggle block 34. An annular plate 41 is installed on the lower side of the annular groove 4 to seal and rotate. The lower side of the annular plate 41 is connected to the nozzle 31 through a pipe. The lower end of the movable tube 302 is connected to the annular groove 4.

[0064] After the cleaning liquid enters the fixed tube 301, it flows into the annular groove 4 through the interactive tube 302, and is then ejected from the nozzle 31 through the pipe. Since the annular plate 41 is sealed and rotatably mounted on the lower side of the annular groove 4, the nozzle 31 can be rotated while ensuring that the pipe is connected to the annular groove 4, thereby changing the orientation of the nozzle 31. In actual use, by changing the orientation of the nozzle 31, different parts of the patient's teeth can be cleaned;

[0065] When cleaning the scaler 23 , the nozzle 31 rotates around the scaler 23 , so that the scaler 23 can be fully rinsed. Therefore, the selective nozzle 31 is more practical.

[0066] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
