[0022] The lamp cylinder 1 and the handle 11 are detachably connected by threads, so as to facilitate removing the handle 11 from the lamp cylinder 1.

[0023] The outer side of the handle 11 is covered with a rubber sleeve for enhancing the friction between the human hand and the handle 11.

[0024] A micro camera is provided in the LED lamp 12 for taking real-time pictures of the inside of the patient's oral cavity and transmitting the captured information in real time, and the light intensity of the LED lamp 12 is adjustable to meet the actual needs in different scenarios.

[0025] It also includes a transparent protective cover 13; a transparent protective cover 13 is detachably connected to the end of the lamp cylinder 1 away from the handle 11.

[0026] To solve the problems mentioned in the background art, when using this multifunctional oral lamp, first load each of the two support rings 202 onto a slide rod 201. Then, manually hold the handle 11 and drive the handle 11 to move. The movement of the handle 11 drives the movement of the lamp barrel 1. The movement of the lamp barrel 1 drives the movement of all connected components, and then the LED lamp 12 is sent into the patient's oral cavity. Then, manually press the button on the lamp barrel 1 to turn on the LED lamp 12, and adjust the brightness of the LED lamp 12 according to the actual usage situation. Then, according to the actual usage situation, manually rotate the worm 203. The rotation of the worm 203 drives the rotation of the worm wheel 205. The rotation of the worm wheel 205 drives the rotation of the rotating shaft 2041. The rotation of the rotating shaft 2041 drives the rotation of the column gear 207. The rotation of the column gear 207 drives the rotation of the tooth ring 206. The rotation of the tooth ring 206 drives the two racks 208 to move away from each other along the corresponding limiting plates 209. The movement of the two racks 208 drives the movement of a corresponding fixed rod 2081. The movement of the two fixed rods 2081 drives the movement of a corresponding slide rod 201. The movement of the two slide rods 201 drives the movement of each of the two support rings 202, thereby adjusting the distance between the two support rings 202, so that the two support rings 202 each wrap around the outside of the patient's teeth, and are locked by the worm 203 and the worm wheel 205, so as to support the patient's oral cavity through the two support rings 202, thus avoiding the problem that the involuntary biting of the patient's mouth interferes with the examination, and being able to control the moving distance of the two racks 208 according to the actual situation, and then control the distance between the two support rings 202, so as to adjust the size of the patient's mouth opening and improve the adaptability of the equipment use.

[0027] It should be noted that for different patients, the two support rings 202 can be removed from the corresponding slide rods 201 according to the actual situation to improve the adaptability. And to improve the success rate of the examination, after the patient's oral cavity is supported by the two support rings 202, manually rotate the entire lamp barrel 1 around the two slide rods 201. The rotation of the lamp barrel 1 drives the rotation of the LED lamp 12, and then adjusts the irradiation angle of the LED lamp 12, so as to be able to examine the patient's oral cavity more comprehensively. And use the micro camera inside the LED lamp 12 to take pictures of the inside of the patient's oral cavity, and transmit the captured information to the external display screen in real time. Then, the medical staff adjusts the position of the LED lamp 12 and the position of the micro camera according to the information on the display screen, so as to improve the accuracy of oral examination. And through the setting of the transparent protective cover 13, the LED lamp 12 and the micro camera can be protected, avoiding saliva in the oral cavity from adhering to the outer surface of the LED lamp 12 and the outer surface of the micro camera, causing occlusion to the LED lamp 12 and the micro camera and resulting in errors in the examination results.

[0032] A plurality of suction holes 4052 are opened on the arc-shaped channel in the support ring 202 for sucking saliva in the patient's oral cavity from different angles.

[0033] The inner wall of the liquid storage cylinder 407 is coated with a hydrophobic coating to facilitate subsequent cleaning of the liquid storage cylinder 407.

[0034] During the process of examining the patient's oral cavity, the patient will involuntarily secrete saliva, which will easily cause a large amount of saliva to accumulate in the patient's oral cavity, easily interfere with the examination, and at the same time block the LED lamp 12, affecting the normal progress of the examination and the accuracy of the examination results. To solve the above problems, both support rings 202 are wrapped around the outside of the patient's teeth, and all air nozzles 4051 are located inside the teeth. All suction holes 4052 are located inside the teeth, and all suction holes 4052 are close to the salivary glands that secrete saliva. Then, by manually pressing the button on the lamp tube 1, the micro pump 401 is started. When the micro pump 401 starts, negative pressure is generated in the three-way pipe 402, and then negative pressure is generated in the catheter 403, the suction pipe 404, and the elbow pipe 405. Finally, the saliva accumulated in the patient's oral cavity is sucked through all the air nozzles 4051 and suction holes 4052, and the saliva flows through the infusion tube 406 into the liquid storage cylinder 407, so that the saliva is stored in the liquid storage cylinder 407, thereby sucking out the saliva accumulated in the patient's oral cavity, reducing the interference of saliva on the examination, enabling the examination operation to proceed normally, improving the accuracy of the examination results, and being able to control the suction intensity of the micro pump 401 to reduce the discomfort of the patient.

[0035] It should be noted that after the two support rings 202 are removed from the two slide bars 201 and the suction pipe 404 is disconnected from the elbow pipe 405, when it is still necessary to suck out the saliva accumulated in the patient's oral cavity, by manually adjusting the angle of the lamp tube 1, the suction pipe 404 is located inside the teeth and close to the salivary glands, and then the micro pump 401 is started and operated in the same way as above to suck out the saliva accumulated in the patient's oral cavity, thereby further improving the adaptability. After the examination is completed, the transparent protective cover 13 is removed and cleaned and disinfected. Then, by manually twisting the handle 11, the handle 11 is removed from the lamp tube 1. Then, the liquid storage cylinder 407 is taken out from the lamp tube 1, and the liquid storage cylinder 407 is disconnected from the infusion tube 406. Then, the liquid storage cylinder 407 is cleaned and sterilized for subsequent use.

[0036] The above embodiments are provided for those skilled in the art to implement or use the present invention. Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention.
