[0002] For the safe use of medical devices, currently, after the dental handpiece is used, steps such as cleaning, drying and oil injection are carried out. In the prior art, when processing the dental handpiece, generally, the outer surface of the dental handpiece is cleaned by manual wiping. Such a cleaning method is not only laborious and time-consuming, but also cannot clean the inside of the dental handpiece, resulting in an unsatisfactory cleaning effect. For the inside of the dental handpiece, manual oil injection is carried out using an oil injector, which requires a large amount of labor and cannot accurately control the oil injection amount, thus causing waste of lubricating oil. In view of this, high-end products that can accurately clean and inject oil into the inside of the dental handpiece have emerged in the prior art, but they are relatively expensive and not suitable for popular use.

[0051]

[0052] The realization, functional features and advantages of the object of the present invention will be further described with reference to the embodiments and the accompanying drawings. Detailed implementation manners

[0053] The technical solutions in the embodiments 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 a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0054] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative position relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0055] In addition, if there are descriptions such as "first" and "second" involved in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears throughout the text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution that satisfies both A and B at the same time. In addition, the technical solutions between the embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0056] With the increasing pursuit of oral health by people, more and more people go to the hospital for oral treatment. The main instrument for oral treatment is the dental handpiece. The interior of the dental handpiece is penetrated by an inner cavity, and there are multiple high-precision parts that cooperate with each other in the inner cavity. Since there are a large number of bacteria and impurities in the oral cavity, during the treatment process, the dental handpiece directly contacts the patient's saliva, blood, and tooth substance. Therefore, the dental handpiece will be severely contaminated and cannot be used for the next patient.

[0057] For the safe use of the instrument, currently, after the dental handpiece is used, steps such as cleaning, drying, and oil injection are carried out. When the prior art processes the dental handpiece, generally, the outer surface of the dental handpiece is cleaned by the method of manual wiping. Such a cleaning method is not only laborious and time-consuming, but also cannot clean the inside of the dental handpiece, resulting in an unsatisfactory cleaning effect. For the inside of the dental handpiece, an oil injector is used for manual oil injection, which requires a large amount of labor and cannot accurately control the oil injection amount, thus causing waste of lubricating oil. In view of this, high-end products that can accurately clean and inject oil into the inside of the dental handpiece have emerged in the prior art, but the price is relatively expensive and not suitable for popular use.

[0058] To improve the above situation, the present invention proposes a cleaning and oil injection control method, aiming to solve the problems of high labor intensity, time-consuming, and incomplete cleaning in the current manual cleaning and oil injection maintenance of dental handpieces.

[0059] Referring to Figure 1 、 Figure 7 and Figure 8 In an embodiment of the present invention, the cleaning and oil injection control method is used for an oil injector, and the cleaning and oil injection control method includes the following steps:

[0060] S100. When a cleaning and oil injection instruction is received, determine the cleaning and oil injection channels of the oil injector according to the cleaning and oil injection instruction, and the cleaning and oil injection channels include a first cleaning and oil injection channel and a second cleaning and oil injection channel;

[0061] S200. Control the first cleaning and oil injection channel and / or the second cleaning and oil injection channel to sequentially clean and inject oil into the inner cavity of the dental handpiece.

[0062] It can be understood that the cleaning and oil injection control method of this embodiment is used for an oil injector. An oil injector is a device used for maintaining dental handpieces, which has functions such as cleaning, lubricating, and removing excess lubricating oil, plays a role in maintaining dental handpieces, and extends the service life of dental handpieces.

[0063] Optionally, the oil injector may include, but is not limited to, a first power device 20, a second power device 30, a cleaning and oil injection device 40, and a control device 10.

[0064] In this embodiment, the first power device 20 and the second power device 30 can be implemented by solenoid valves and motors connected to the solenoid valves. Optionally, the solenoid valve can be any one of a micro solenoid valve, a high-precision solenoid valve, a pulse solenoid valve, and a proportional solenoid valve. In this embodiment, the solenoid valves of the first power device 20 and the second power device 30 are implemented by micro solenoid valves. The micro solenoid valve has characteristics such as simple structure, small size, light weight, and is convenient for installation, maintenance, and replacement, and is widely used in dental instruments such as dental handpieces. Optionally, the motor can be any one of a brushed motor, a brushless motor, a coreless motor, or a conditional brushed motor. In this embodiment, the motors of the first power device 20 and the second power device 30 are implemented by brushed motors, and the brushed motors of the first power device 20 and the second power device 30 are each used to connect a dental handpiece. The brushed motor is the most common type of electric motor in dental handpieces. It consists of two components, a carbon brush and a commutator, which can provide continuous power for the dental handpiece, enabling the dental handpiece to perform cutting and grinding operations, and quickly and accurately assisting the doctor to complete the treatment.

[0065] Optionally, the cleaning and oiling device 40 may include, but is not limited to, a gas supply component 41, a cleaning component 42, and an oiling component 43. The input end of the gas supply component 41 is used to connect to a pneumatic source so that the pneumatic source can supply gas to it; the first output end and the second output end of the gas supply component 41 are respectively connected to the input ends of the cleaning component 42 and the oiling component 43 to provide the power for the cleaning component 42 to output the cleaning liquid and the power for the oiling component 43 to output the lubricating oil. The first output end and the second output end of the cleaning component 42 are respectively connected to the solenoid valves of the first power device 20 and the second power device 30, so as to output the cleaning liquid to the inner cavity of the dental handpiece connected to the corresponding motor through the solenoid valves of the first power device 20 and the second power device 30. The first output end and the second output end of the oiling component 43 are respectively connected to the solenoid valves of the first power device 20 and the second power device 30, so as to output the lubricating oil to the inner cavity of the dental handpiece connected to the corresponding motor through the solenoid valves of the first power device 20 and the second power device 30.

[0066] It should be noted that the gas supply component 41, the cleaning component 42, the oiling component 43, and the first power device 20 are connected to each other to form the first cleaning and oiling channel of the oiling machine, and the gas supply component 41, the cleaning component 42, the oiling component 43, and the second power device 30 are connected to each other to form the second cleaning and oiling channel of the oiling machine. Since each of the first power device 20 and the second power device 30 is connected to a dental handpiece, it can be seen that the first cleaning and oiling channel and the second cleaning and oiling channel are each connected to the inner cavity of a dental handpiece.

[0067] In order to enable the first cleaning and oiling channel and the second cleaning and oiling channel of the oiling machine to intelligently clean and oil the inner cavity of the dental handpiece, in addition to the above-mentioned devices, the oiling machine of this embodiment further includes a triggering device 50. Optionally, the triggering device 50 may include, but is not limited to, a first trigger 51 and a second trigger 52. Optionally, the first trigger 51 and the second trigger 52 may be any one of a touch key, a physical button, an infrared sensing key, and a voice control. Specifically, no special limitation is made here. The first trigger 51 is used to output a first cleaning and oiling instruction indicating that the cleaning and oiling channel of the oiling machine is the first cleaning and oiling channel when being triggered, and the second trigger 52 is used to output a second cleaning and oiling instruction indicating that the cleaning and oiling channel of the oiling machine is the second cleaning and oiling channel when being triggered.

[0068] Combined with the above content, when the user only needs to process a used dental handpiece, the dental handpiece can be first installed on the motor of the first power device 20 or the second power device 30. For example, it is installed on the motor of the first power device 20, and then the first trigger 51 is triggered, so that the first trigger 51 outputs a first cleaning and oiling instruction to the control device 10. The control device 10 determines that the cleaning and oiling channel of the oiler is the first cleaning and oiling channel according to the received first cleaning and oiling instruction, and controls the solenoid valve of the first power device 20 to be energized, so that the cleaning and oiling device 40 can sequentially clean and oil the inner cavity of the dental handpiece connected to the corresponding motor through the solenoid valve of the first power device 20.

[0069] When the user needs to process at least two used dental handpieces, at least two dental handpieces can be respectively installed on the motors of the first power device 20 and the second power device 30, and then the first trigger 51 and the second trigger 52 are triggered, so that the first trigger 51 and the second trigger 52 respectively output a first cleaning and oiling instruction and a second cleaning and oiling instruction to the control device 10. It should be noted that the first trigger 51 and the second trigger 52 can be triggered at the same moment in the same time period, or at different moments in the same time period. In this embodiment, the first trigger 51 and the second trigger 52 are triggered at the same moment in the same time period to ensure that the two dental handpieces can be cleaned and oiled in the same time period. The control device 10 determines that the cleaning and oiling channels of the oiler are the first cleaning and oiling channel and the second cleaning and oiling channel according to the received first cleaning and oiling instruction and the second cleaning and oiling instruction, and controls the solenoid valves of the first power device 20 and the second power device 30 to be energized, so that the cleaning and oiling device 40 can sequentially clean and oil the inner cavity of the dental handpiece connected to the corresponding motor through the solenoid valve of the first power device 20, and sequentially clean and oil the inner cavity of the dental handpiece connected to the corresponding motor through the solenoid valve of the second power device 30.

[0070] The cleaning and oil injection control method of the technical solution of the present invention is used for an oil injection machine. The cleaning and oil injection control method includes the following steps: when a cleaning and oil injection instruction is received, determine the cleaning and oil injection channels of the oil injection machine according to the cleaning and oil injection instruction. The cleaning and oil injection channels include a first cleaning and oil injection channel and a second cleaning and oil injection channel; control the first cleaning and oil injection channel and / or the second cleaning and oil injection channel to sequentially clean and inject oil into the inner cavity of the dental handpiece. The technical solution of the present invention controls steps such as cleaning and oil injection of the inner cavity of the dental handpiece by receiving a cleaning and oil injection instruction. The above steps can be completed with only one operation, which not only ensures the cleaning and oil injection effects, but also reduces the operation of personnel, improves the cleaning efficiency of the dental handpiece, and solves the problems of high labor intensity, time-consuming, and incomplete cleaning in the current manual cleaning and oil injection maintenance of dental handpieces. Moreover, the structure of the oil injection machine proposed by the technical solution of the present invention is simple, the production cost is small, the cost performance is high, and it has good economic benefits.

[0071] Refer to Figure 2 , in an embodiment of the present invention, the cleaning and oil injection instruction includes a first cleaning and oil injection instruction and a second cleaning and oil injection instruction;

[0072] The step of determining the cleaning and oil injection channels of the oil injection machine according to the cleaning and oil injection instruction specifically includes:

[0073] S110. When it is determined that the cleaning and oil injection instruction is the first cleaning and oil injection instruction, determine the first cleaning and oil injection channel as the cleaning and oil injection channel of the oil injection machine;

[0074] S120. When it is determined that the cleaning and oil injection instruction is the second cleaning and oil injection instruction, determine the second cleaning and oil injection channel as the cleaning and oil injection channel of the oil injection machine.

[0075] In this embodiment, the oil injection machine determines the cleaning and oil injection channels according to the received cleaning and oil injection instruction. The cleaning and oil injection channels include a first cleaning and oil injection channel and a second cleaning and oil injection channel. When the cleaning and oil injection instruction of the control device 10 of the oil injection machine is the first cleaning and oil injection instruction, determine the first cleaning and oil injection channel as the cleaning and oil injection channel of the oil injection machine, and control the solenoid valve of the first power device 20 to be energized, so that the cleaning and oil injection device 40 can sequentially clean and inject oil into the inner cavity of the dental handpiece connected to the corresponding motor through the solenoid valve of the first power device 20; when the cleaning and oil injection instruction of the control device 10 of the oil injection machine is the second cleaning and oil injection instruction, determine the second cleaning and oil injection channel as the cleaning and oil injection channel of the oil injection machine, and control the solenoid valve of the second power device 30 to be energized, so that the cleaning and oil injection device 40 can sequentially clean and inject oil into the inner cavity of the dental handpiece connected to the corresponding motor through the solenoid valve of the second power device 30.

[0076] Refer to Figure 3, in an embodiment of the present invention, the oil filling machine includes a first power device 20, a second power device 30, and a cleaning and oil filling device 40. The first power device 20 is connected to the cleaning and oil filling device 40 to form a first cleaning and oil filling channel, and the second power device 30 is connected to the cleaning and oil filling device 40 to form a second cleaning and oil filling channel;

[0077] The steps of controlling the first cleaning and oil filling channel and / or the second cleaning and oil filling channel to sequentially clean and fill the inner cavity of the dental handpiece specifically include:

[0078] S210. Control the first power device and / or the second power device to be powered on, and control the cleaning and oil filling device to sequentially perform blowing, cleaning, primary drying, oil filling, and secondary drying operations on the inner cavity of the dental handpiece.

[0079] As can be seen from the above embodiments, the oil filling machine includes a first power device 20, a second power device 30, and a cleaning and oil filling device 40. Among them, the cleaning and oil filling device 40 includes an air supply component 41, a cleaning component 42, and an oil filling component 43. The air supply component 41, the cleaning component 42, the oil filling component 43, and the first power device 20 are connected to each other to form a first cleaning and oil filling channel of the oil filling machine, and the air supply component 41, the cleaning component 42, the oil filling component 43, and the second power device 30 are connected to each other to form a second cleaning and oil filling channel of the oil filling machine.

[0080] In this embodiment, when the cleaning and oil filling instruction of the control device 10 of the oil filling machine is the first cleaning and oil filling instruction, it is determined that the first cleaning and oil filling channel is the cleaning and oil filling channel of the oil filling machine, and the electromagnetic valve of the first power device 20 is controlled to be powered on, so that the cleaning and oil filling device 40 can sequentially perform blowing, cleaning, primary drying, oil filling, and secondary drying operations on the inner cavity of the dental handpiece connected to the corresponding motor through the electromagnetic valve of the first power device 20; when the cleaning and oil filling instruction of the control device 10 of the oil filling machine is the second cleaning and oil filling instruction, it is determined that the second cleaning and oil filling channel is the cleaning and oil filling channel of the oil filling machine, and the electromagnetic valve of the second power device 30 is controlled to be powered on, so that the cleaning and oil filling device 40 can sequentially perform blowing, cleaning, primary drying, oil filling, and secondary drying operations on the inner cavity of the dental handpiece connected to the corresponding motor through the electromagnetic valve of the second power device 30.

[0081] Refer to Figure 4 , in an embodiment of the present invention, the cleaning and oil filling device 40 includes an air supply component 41, a cleaning component 42 connected to the air supply component 41, and an oil filling component 43;

[0082] The steps of controlling the cleaning and oil filling device 40 to sequentially perform blowing, cleaning, primary drying, oil filling, and secondary drying operations on the inner cavity of the dental handpiece specifically include:

[0083] S211. Control the gas supply component to be powered on and output gas to the inner cavity of the dental handpiece through the first power device and / or the second power device;

[0084] S212. Control the cleaning component to be powered on and output cleaning liquid to the inner cavity of the dental handpiece through the first power device and / or the second power device, and cut off the power after a preset cleaning duration;

[0085] S213. After the cleaning component is powered off for a first preset duration, control the oil injection component to be powered on and output lubricating oil to the inner cavity of the dental handpiece through the first power device and / or the second power device, and cut off the power after a preset oil injection duration, where the preset oil injection duration is greater than the preset cleaning duration;

[0086] S214. After the oil injection component is powered off for a second preset duration, control the cleaning and oil injection device 40 to be powered off, where the second preset duration is greater than the first preset duration.

[0087] In this embodiment, when the control device 10 of the oil injector determines that the cleaning and oil injection instruction is the first cleaning and oil injection instruction, it determines that the first cleaning and oil injection channel is the cleaning and oil injection channel of the oil injector, controls the solenoid valve of the first power device 20 to be powered on, controls the gas supply component 41 to be powered on and outputs gas to the inner cavity of the dental handpiece connected to the corresponding motor through the solenoid valve of the first power device 20 to displace the water in the inner cavity.

[0088] Further, the control device 10 controls the cleaning component 42 to be powered on and outputs cleaning liquid to the inner cavity of the dental handpiece connected to the corresponding motor through the solenoid valve of the first power device 20 to clean the inner cavity. After a preset cleaning duration, the cleaning component 42 is powered off. The preset cleaning duration is 800 milliseconds. According to the pipeline characteristics of this oil injector, when outputting the cleaning liquid, the power-on time range of the cleaning component 42 from 200 milliseconds to 3000 milliseconds is suitable for the use of this oil injector. After experimental comparison, a better cost performance is achieved at 800 milliseconds, which not only meets the requirements for cleaning the dental handpiece but also saves the usage cost of the cleaning liquid.

[0089] It should be understood that during the power-off period of the cleaning component 42, the solenoid valve of the first power device 20 is continuously powered on for a first preset duration, which is specifically 30 seconds, to blow out the cleaning liquid in the inner cavity of the dental handpiece, facilitating the next oil injection operation. After the end of the first preset duration, the control device 10 controls the oil injection component 43 to be powered on and outputs lubricating oil to the inner cavity of the dental handpiece connected to the corresponding motor through the solenoid valve of the first power device 20 to inject oil into the inner cavity. After a preset oil injection duration, the oil injection component 43 is powered off. The preset oil injection duration is 900 milliseconds. According to the pipeline characteristics of this oil injector, when outputting lubricating oil, the power-on time range of the oil injection component 43 from 200 milliseconds to 3000 milliseconds is suitable for the use of this oil injector. After experimental comparison, a better cost performance is achieved at 900 milliseconds, which not only meets the lubrication needs of the dental handpiece but also saves the use cost of the lubricating oil.

[0090] Similarly, during the power-off period of the oil injection component 43, the solenoid valve of the first power device 20 is also continuously powered on for a second preset duration, which is specifically 40 seconds, to blow out the lubricating oil in the inner cavity of the dental handpiece and maintain the cleanliness of the inner cavity of the dental handpiece. After the end of the second preset duration, the control device 10 controls all the devices of the cleaning and oil injection device 40 to be powered off, completing the cleaning and oil injection work of the inner cavity of the dental handpiece.

[0091] Based on the above content, when the control device 10 of the oil injector determines that the cleaning and oil injection instruction is the second cleaning and oil injection instruction, it determines that the second cleaning and oil injection channel is the cleaning and oil injection channel of the oil injector, and the working process of the second cleaning and oil injection channel is similar to the above process and will not be repeated here.

[0092] Refer to Figure 5 In an embodiment of the present invention, the cleaning and oil injection device 40 further includes an exhaust component 44 connected to the cleaning component 42 and the oil injection component 43;

[0093] The step of controlling the cleaning and oil injection device 40 to be powered off after the oil injection component 43 is powered off for the second preset duration specifically includes:

[0094] S2141. Control the air supply component to be powered off after the oil injection component is powered off for a third preset duration, and control the exhaust component to be powered on after the oil injection component is powered off for a fourth preset duration, where the fourth preset duration is greater than the third preset duration and less than the second preset duration.

[0095] Based on the above embodiments, in this embodiment, after the oil injection assembly 43 is powered off for a third preset duration, the air supply assembly 41 is controlled to be powered off to stop removing the moisture in the inner cavity of the dental handpiece. And after the oil injection assembly 43 is powered off for a fourth preset duration, the exhaust assembly 44 is controlled to be powered on, that is, the exhaust assembly 44 is opened, so as to discharge the gas in the oil injection machine pipeline to the external environment, in preparation for the next cleaning and oil injection work. Among them, the third preset duration is 36 seconds after the oil injection assembly 43 is powered off, and the fourth preset duration is 37 to 40 seconds after the oil injection assembly 43 is powered off.

[0096] The present invention also provides a control device 10. Refer to Figure 6 , this control device 10 includes a memory 11 and a processor 12. The processor 12 stores a cleaning and oil injection control program executed by the processor 12. When the cleaning and oil injection control program is executed by the processor 12, it implements the cleaning and oil injection control method as described above. The specific structure of the cleaning and oil injection control method refers to the above embodiments. Since this control device 10 adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one.

[0097] The present invention also provides an oil injection machine, which includes a first power device 20 and / or a second power device 30, a cleaning and oil injection device 40, a trigger device 50, and a control device 10. The specific structure of the control device 10 refers to the above embodiments. Since this oil injection machine adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one.

[0098] Refer to Figures 7 to 10 , in this embodiment, the oil injection machine includes a first power device 20, a second power device 30, a cleaning and oil injection device 40, a trigger device 50, and a control device 10. The first power device 20, the second power device 30, the cleaning and oil injection device 40, and the trigger device 50 are respectively electrically connected to the control device 10.

[0099] Optionally, the first power device 20 can be implemented by using a first solenoid valve 21 and a first motor connected to the first solenoid valve 21. The second power device 30 can be implemented by using a second solenoid valve 31 and a second motor connected to the second solenoid valve 31. Wherein, the first motor and the second motor are also respectively used to connect a dental handpiece. Optionally, the first solenoid valve 21 and the second solenoid valve 31 can be any one of a micro solenoid valve, a high-precision solenoid valve, a pulse solenoid valve, and a proportional solenoid valve. In this embodiment, the first solenoid valve 21 and the second solenoid valve 31 are implemented by using micro solenoid valves. The micro solenoid valve has the characteristics of simple structure, small size, light weight, and is convenient for installation, maintenance and replacement, etc., and is widely used in dental instruments such as dental handpieces. Optionally, the motor can be any one of a brushed motor, a brushless motor, a coreless motor or a conditional brushed motor. In this embodiment, the first motor and the second motor are implemented by using brushed motors. The brushed motor is the most common type of electric motor in dental handpieces. It consists of two components, a carbon brush and a commutator, and can provide continuous power for the dental handpiece, enabling the dental handpiece to perform cutting and grinding operations, and quickly and accurately assisting the doctor to complete the treatment.

[0100] Optionally, the cleaning and oil injection device 40 may include, but is not limited to, a gas supply component 41, a cleaning component 42, and an oil injection component 43. The input end of the gas supply component 41 is used to connect to a gas pressure source so that the gas pressure source can provide gas for it; the first output end and the second output end of the gas supply component 41 are respectively connected to the input ends of the cleaning component 42 and the oil injection component 43 to provide power for the cleaning component 42 to output cleaning liquid and provide power for the oil injection component 43 to output lubricating oil. The first output end and the second output end of the cleaning component 42 are respectively connected to the first input ends of the first solenoid valve 21 and the second solenoid valve 31, so as to output cleaning liquid to the inner cavity of the dental handpiece connected to the first motor through the first solenoid valve 21, and output cleaning liquid to the inner cavity of the dental handpiece connected to the second motor through the second solenoid valve 31. The first output end and the second output end of the oil injection component 43 are respectively connected to the second input ends of the first solenoid valve 21 and the second solenoid valve 31, so as to output lubricating oil to the inner cavity of the dental handpiece connected to the first motor through the first solenoid valve 21, and output lubricating oil to the inner cavity of the dental handpiece connected to the second motor through the second solenoid valve 31. It should be noted that the gas supply component 41, the cleaning component 42, the oil injection component 43, and the first power device 20 are connected to each other to form a first cleaning and oil injection channel of the oil injection machine, and the gas supply component 41, the cleaning component 42, the oil injection component 43, and the second power device 30 are connected to each other to form a second cleaning and oil injection channel of the oil injection machine. Since each of the first power device 20 and the second power device 30 is connected to a dental handpiece, it can be inferred therefrom that the first cleaning and oil injection channel and the second cleaning and oil injection channel each communicate with the inner cavity of a dental handpiece.

[0101] Optionally, the triggering device 50 may include, but is not limited to, a first trigger 51 and a second trigger 52. Optionally, the first trigger 51 and the second trigger 52 may be any one of a touch key, a physical button, an infrared sensing key, and a voice control. Specifically, no special limitation is made here. The first trigger 51 is used to output a first cleaning and oil injection instruction indicating that the cleaning and oil injection channel of the oil injection machine is the first cleaning and oil injection channel when triggered; the second trigger 52 is used to output a second cleaning and oil injection instruction indicating that the cleaning and oil injection channel of the oil injection machine is the second cleaning and oil injection channel when triggered.

[0102] Combined with the above content, when the user only needs to process one used dental handpiece, the dental handpiece can be first installed on the first motor or the second motor. For example, when installed on the first motor, then trigger the first trigger 51, so that the first trigger 51 outputs a first cleaning and oil injection instruction to the control device 10. The control device 10 determines that the cleaning and oil injection channel of the oil injection machine is the first cleaning and oil injection channel according to the received first cleaning and oil injection instruction, and controls the first solenoid valve 21 to be energized, so that the cleaning component 42 can first clean the inner cavity of the dental handpiece connected to the first motor through the first solenoid valve 21, and after the cleaning work of the cleaning component 42 is completed, the oil injection component 43 can inject oil into the inner cavity of the dental handpiece of the first motor through the first solenoid valve 21.

[0103] When the user needs to process at least two used dental handpieces, at least two dental handpieces can be respectively installed on the first motor and the second motor, and then trigger the first trigger 51 and the second trigger 52, so that the first trigger 51 and the second trigger 52 respectively output a first cleaning and oil injection instruction and a second cleaning and oil injection instruction to the control device 10. It should be noted that the first trigger 51 and the second trigger 52 can be triggered at the same moment in the same period, or at different moments in the same period. In this embodiment, the first trigger 51 and the second trigger 52 are triggered at the same moment in the same period to ensure that the two dental handpieces can be cleaned and oiled in the same period. The control device 10 determines that the cleaning and oil injection channels of the oil injection machine are the first cleaning and oil injection channel and the second cleaning and oil injection channel according to the received first cleaning and oil injection instruction and the second cleaning and oil injection instruction, and controls the first solenoid valve 21 and the second solenoid valve 31 to be energized, so that the cleaning component 42 can first clean the inner cavities of the dental handpieces connected to the first motor and the second motor through the first solenoid valve 21 and the second solenoid valve 31 respectively, and after the cleaning component 42 completes the cleaning work, the corresponding oil injection components 43 can inject oil into the inner cavities of the dental handpieces connected to the first motor and the second motor through the first solenoid valve 21 and the second solenoid valve 31 respectively.

[0104] Optionally, in addition to the first trigger member 51 and the second trigger member 52, the triggering device 50 further includes a power-on / off member 53. Optionally, the power-on / off member 53 can also be any one of a touch key, a physical button, an infrared induction key, and a voice control. There is no special limitation in this regard. The power-on member is used to output a power-on / off instruction indicating that the working state of the oil filling machine is the start state or the shutdown state when triggered.

[0105] Optionally, in order to enable the user to intuitively understand the working state of the oil filling machine, the oil filling machine further includes a reminder device 60, and the reminder device 60 is electrically connected to the control device 10. In this embodiment, the reminder device 60 is implemented by an indicator light and a buzzer 62. In actual application, after the oil filling machine is connected to the power supply and enters the power-on state, the indicator light is not on and the buzzer 62 sounds once; when the power-on / off member 53 is triggered once, the indicator light is turned on and switches to the first color, the first color is green, and the buzzer 62 sounds once, and at this time the oil filling machine switches to the standby state; when the power-on / off member 53 is triggered twice, the indicator light is turned off and the buzzer 62 sounds twice, and at this time the oil filling machine switches back to the standby state. It should be noted that only when the oil filling machine is in the standby state, triggering the first trigger member 51 and the second trigger member 52 is effective, and triggering the first trigger member 51 and the second trigger member 52 in the power-on state is ineffective, so as to reduce the situation of the user accidentally triggering the first trigger member 51 and the second trigger member 52 and avoid the occurrence of accidental cleaning and oil filling.
