AI Technical Summary
When using cleaning fluid in existing pneumatic dental treatment devices, it is difficult for the cleaning fluid to penetrate into the gap between the rotating parts, and the sprayed cleaning fluid is easily sprayed on the operator, affecting operation.
An adapter is designed, including a cleaning fluid passage, a plug and a cylindrical notch. By inserting the nozzle into the cleaning fluid passage and the plug seals the outlet passage, ensuring that the cleaning fluid cannot be sprayed from the outlet passage and penetrates into the gap between the rotating parts under hydraulic action.
It effectively prevents the cleaning liquid from spraying from the outlet duct, ensuring that the cleaning liquid can penetrate into the gap between the rotating parts smoothly, improves the cleaning effect, and avoids the impact of the cleaning liquid on the operator.

Abstract
Description
Technical field:
[0002] The invention relates to an accessory on a medical device, in particular to a joint on a cleaning liquid spray head for a handheld dental power machine. Background technology:
[0004] like Figure 3 As shown, the tail of the existing pneumatic dental treatment device b is provided with an air inlet 5 and an air outlet 7 arranged side by side. Compressed air is introduced from the air inlet 5 and then discharged from the air outlet 7. In this way, the power head can be driven to rotate by introducing compressed air, so as to drive the corresponding dental components to treat the teeth. After using this pneumatic dental treatment device for a period of time, it is necessary to spray a cleaning lubricant into the air inlet through the nozzle 4, firstly to clean the channel inside the rotating head and the gap between the rotating parts, to clean out the impurities infiltrated during the tooth treatment process, and secondly to add lubricant to the gap between the rotating parts. Since the cleaning agent is directly sprayed into the air inlet 5 of the pneumatic dental treatment device b through the nozzle 4 inserted into the air inlet on the sprinkler a, the cleaning liquid will be sprayed out from the air outlet under the driving of the spraying pressure, firstly, it is not easy to penetrate into the gap between the rotating parts, and secondly, the sprayed cleaning liquid will be sprayed on the operator, affecting the normal cleaning operation of the operator. Summary of the invention:
[0006] The object of the present invention is to provide an adapter which prevents cleaning liquid from spraying out from the air outlet of a pneumatic dental treatment instrument and enables the cleaning liquid to smoothly penetrate into the gap between rotating parts.
[0007] The present invention is implemented as follows: it includes an adapter body, a cleaning liquid channel arranged on the adapter body, and a plug arranged on the adapter body and located next to the cleaning liquid channel, wherein the channel diameter at one end of the cleaning liquid channel corresponds to the diameter of the nozzle on the sprinkler, and the diameter of the other end of the cleaning liquid channel corresponds to the outer diameter of the air inlet of the pneumatic dental treatment instrument. A cylindrical recess is arranged on the adapter body next to the other end of the cleaning liquid channel, and the diameter of the cylindrical recess corresponds to the outer diameter of the air outlet of the pneumatic dental treatment instrument. The plug is arranged in the cylindrical recess, and the diameter of the plug corresponds to the inner diameter of the air outlet of the pneumatic dental treatment instrument.
[0008] When in use, the other end of the cleaning liquid channel on the adapter body and the cylindrical recess are respectively sleeved on the air inlet and outlet of the pneumatic dental treatment instrument, the plug is inserted into the air outlet to close the air outlet, and then the nozzle on the sprinkler is inserted into the cleaning liquid channel from one end of the cleaning liquid channel, and the cleaning liquid is sprayed into the cleaning liquid channel through the nozzle. Since the air outlet is closed, the cleaning liquid cannot be sprayed out from the air outlet, which prevents the sprayed cleaning liquid from spraying on the operator and affecting the normal cleaning operation of the operator. At the same time, the sprayed cleaning liquid, under the action of hydraulic pressure, penetrates into the gap between the rotating parts and overflows from the driving power head to effectively clean and lubricate the rotating parts. The plug is set in the cylindrical recess, so that the air outlet is closed when the adapter is connected, which is very convenient to use. In addition, the pressure applied by the nozzle on the adapter can be used to keep the plug closed, prevent the plug from falling off under the pressure of the cleaning liquid, and ensure the closing effect of the plug.
[0009] Here, the material of the adapter is silicone, and the elasticity of silicone is used to ensure the sealing of the connection and prevent the cleaning liquid from leaking out from the channel between the cannula and one end of the cleaning liquid channel under pressure.
[0010] Compared with the prior art, the present invention has the advantages of preventing the cleaning liquid from spraying out from the air outlet of the pneumatic dental treatment instrument, so that the cleaning liquid can smoothly penetrate into the rotating parts. Description of the drawings:
[0012] Figure 1 It is a structural schematic diagram of the present invention;
[0013] Figure 2 It is a usage state diagram of the present invention;
[0014] Figure 3 A state diagram for an existing pneumatic dental unit that uses spray irrigation for cleaning. Specific implementation method:
[0016] The present invention is now described in further detail with reference to the accompanying drawings and embodiments:
[0017] like Figure 1As shown, the present invention includes an adapter body 1 made of silicone, a cleaning liquid channel 2 arranged on the adapter body 1, and a plug 3 arranged on the adapter body 1 and located next to the cleaning liquid channel 2. The channel diameter of one end 2a of the cleaning liquid channel 2 corresponds to the diameter of the nozzle 4 on the sprinkler a, and the diameter of the other end 2b of the cleaning liquid channel 2 corresponds to the outer diameter of the air inlet 5 of the pneumatic dental treatment device b. A cylindrical recess 6 is arranged on the adapter body 1 next to the other end 2b of the cleaning liquid channel 2, and the diameter of the cylindrical recess 6 corresponds to the outer diameter of the air outlet 7 of the pneumatic dental treatment device b. The plug 3 is arranged on the axis inside the cylindrical recess 6, and the diameter of the plug 3 corresponds to the inner diameter of the air outlet 7 of the pneumatic dental treatment device b.
[0018] like Figure 2 As shown, when in use, the other end 2b of the cleaning liquid channel 2 on the adapter body 1 and the cylindrical recess 6 are respectively sleeved on the air inlet 5 and the air outlet 7 of the pneumatic dental treatment instrument b, the plug 3 is inserted into the air outlet 7 to close the air outlet 7, and then the nozzle 4 on the sprinkler a is inserted into the cleaning liquid channel 2 from one end 2a of the cleaning liquid channel 2, and the cleaning liquid is sprayed through the nozzle 4. Since the air outlet 7 is closed by the plug 3, the cleaning liquid cannot be sprayed out from the air outlet 7, thereby preventing the sprayed cleaning liquid from spraying onto the operator and affecting the operator's normal cleaning operation. At the same time, the sprayed cleaning liquid, under the action of the hydraulic pressure, penetrates into the gap between the rotating parts and overflows from the driving power head 8, thereby effectively cleaning and lubricating the rotating parts.
