Description

Technical Field

[0001] This utility model relates to the field of dental drill technology, and in particular to a dental drill device, a voltage regulator for a dental drill, and its pneumatic switch. Background Technology

[0002] Dental drills, commonly used dental treatment devices in modern dentistry, typically rely on high-pressure gas to drive an internal turbine structure for high-speed rotation. In existing technologies, the high-pressure gas not only drives the drill body but also acts on the accompanying fiber optic box control module. The gas pressure triggers a conductive silicone button to open the fiber optic box, thereby providing the drill with a light source signal compatible with its operating voltage.

[0003] However, the traditional fiber optic box opening mechanism has a significant flaw: due to the generally high driving pressure of the high-pressure gas system (typically 0.2-0.6 MPa), the instantaneous impact force when directly applied to the conductive silicone button far exceeds the mechanical tolerance threshold of the button material. Over long-term use, this overload pressure can easily cause deformation of the conductive silicone structure, contact fatigue, or even breakage, leading to button failure and poor circuit contact. This flaw not only reduces the control reliability of the fiber optic box but also significantly increases the maintenance frequency and operating costs of the equipment, becoming a technical bottleneck restricting the overall durability of the dental drill system.

[0048] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0049] Example 1

[0050] See Figure 1-4 The pneumatic switch for a voltage regulator of a dental drill proposed in this embodiment is used to turn the voltage regulator on and off.

[0051] This pneumatic switch includes a pneumatic valve 4 and an infrared beam sensor 5.

[0052] The pneumatic valve 4 and the infrared beam sensor 5 can be installed on the regulator body 1. The valve body 41 of the pneumatic valve 4 is connected to a high-pressure air source, and the valve body 41 is provided with a telescopic push rod 42. The push rod 42 and the infrared beam sensor 5 are arranged opposite each other. The infrared beam sensor 5 has a transmitting end and a receiving end, and an infrared light path is formed between the transmitting end and the receiving end.

[0053] When the push rod 42 is in an extended state driven by the high-pressure gas output from the high-pressure gas source, the push rod 42 blocks the infrared light path, and the pneumatic switch is turned on.

[0054] When the high-pressure gas source stops outputting high-pressure gas, the push rod 42 returns to its shortened state, disengaging from the infrared light path and closing the pneumatic switch.

[0055] It should be noted that the resetting and shortening of the push rod 42 is driven by the rebound force of the spring inside the valve body 41. This return method is the conventional working principle of the pneumatic valve 4 and is a conventional setting in this field. Similarly, the blocking and connection of the infrared light path of the infrared beam sensor 5 is a conventional working principle and a conventional setting in this field, and does not involve any improvement or use of computer programs.

[0056] The pneumatic switch of this voltage regulator is driven by high-pressure gas from a high-pressure gas source, which extends the push rod 42 on the valve body 41 to cooperate with the infrared through-beam sensor 5 to open and close the pneumatic switch. Compared with silicone, which has a weaker load-bearing capacity, this application uses a solid structural component, the pneumatic valve 4, which is made of a harder material to bear the driving force of the high-pressure gas. It has a stronger load-bearing capacity, is not easily damaged, and has a longer service life.

[0057] Furthermore, the infrared beam sensor 5 is U-shaped, and the opening of the U-shaped groove of the infrared beam sensor 5 faces the push rod 42.

[0058] When push rod 42 is in the extended state, push rod 42 extends into the U-shaped groove to block the infrared light path.

[0059] When push rod 42 is in the shortened state, push rod 42 disengages from the U-shaped groove to disengage from the infrared light path.

[0060] It should be noted that, in Example 2

[0061] Based on Embodiment 1, this embodiment also provides a voltage regulator for a dental drill, used to supply an appropriate voltage to the lighting lamp on the dental drill. This voltage regulator includes the pneumatic switch of Embodiment 1, and also includes a regulator body 1, a controller 7 and a power supply circuit.

[0062] Both the controller 7 and the power supply circuit are located in the voltage regulator body 1. The output terminal of the infrared beam sensor 5 is connected to the controller 7, and the controller 7 is connected to the power supply circuit.

[0063] When push rod 42 blocks the infrared light path, the pneumatic switch is turned on, and controller 7 controls the power supply circuit to conduct, so as to supply power to the light on the dental drill.

[0064] When the high-pressure gas source stops outputting high-pressure gas, the push rod 42 resets and is in the shortened state. When the push rod 42 is disengaged from the infrared light path, the controller 7 controls the power supply circuit to disconnect.

[0065] Specifically, the controller 7 can control the power supply circuit to conduct while also controlling the output voltage and power supply duration of the power supply circuit, so as to supply the set voltage value to the lighting lamp on the dental drill within a set time.

[0066] It should be noted that the controller 7 controls the power supply circuit to turn on, the voltage value output by the power supply circuit, and the power supply duration, all of which are standard operating principles of the controller 7 and are conventional settings in this field. They do not involve any improvement or use of computer programs.

[0067] Preferably, the pressure regulator body 1 is further provided with a pneumatic valve seat 6. The pneumatic valve seat 6 has a mounting groove for mounting the valve body 41. The side wall of the pneumatic valve seat 6 has a guide groove 61 extending along the axial direction of the valve body 41. The guide groove 61 is used to accommodate and allow the push rod 42 to extend and retract, so as to improve the alignment accuracy between the extension path of the push rod 41 and the infrared beam sensor 5.

[0068] Specifically, the pneumatic valve 4, the infrared beam sensor 5, and the controller 7 are all located inside the pressure regulator body 1.

[0069] Furthermore, the air connector 43 of the valve body 41 is used to connect to a high-pressure air source. The air connector 43 extends out of the regulator body 1 to facilitate connection to the high-pressure air source.

[0070] Specifically, the voltage regulator also includes an input interface 2 and an output interface 3 disposed on the regulator body 1.

[0071] Input interface 2 and output interface 3 are connected via power supply circuit 2. Input interface 2 is connected to the power supply via a wire, and output interface 3 is connected to the light on the dental drill via a wire.

[0072] When power supply circuit 2 is turned on, output interface 3 can supply power to the lighting lamp via wires.

[0073] Furthermore, this voltage regulator also includes a button 8 and a display screen 9 disposed on the surface of the regulator body 1, both of which are connected to the controller 7.

[0074] Button 8 includes a voltage adjustment and delay switching button, a value increase button, and a value decrease button.

[0075] In use, the voltage value and delay time (power supply time) can be input to the controller 7 via button 8. The controller 7 controls the output interface 3 to output the set voltage value to the lighting lamp within the set time. The voltage output value and voltage delay time are displayed on the display screen 9 to improve the ease of operation, intuitiveness and adjustment accuracy.

[0076] Preferably, the regulator body 1 is provided with multiple parallel lighting circuits, each lighting circuit including an independent pneumatic valve 4, a sensor 5 and an output interface 3.

[0077] Therefore, the voltage regulator body 1 can supply power to the lights of multiple dental drills: when in use, the output interfaces 3 of multiple lighting circuits are connected to the lights of multiple dental drills through wires, and the controller 7 controls the conduction or cut-off of multiple lighting circuits, and controls the multiple output interfaces 3 to output a set voltage value for the corresponding dental drill lights within a set time, so as to output a suitable voltage for different models of dental drills and ensure the lighting time.

[0078] More preferably, it also includes a switching switch 10 disposed on the voltage regulator body 1.

[0079] The output of the switch 10 is connected to the controller 7. When the switch 10 is adjusted, the controller 7 can control the on or off of each lighting circuit to supply power to the required lighting for the dental drill.

[0080] It should be noted that the process of switching the controller 7 on or off the lighting circuit through the switch 10 is based on the conventional working principle of the controller 7 and the switch 10, which is a conventional setting in this field and does not involve any improvement or use of computer programs. It only provides the connection relationship between the two.

[0081] Furthermore, the controller 7 includes a microcontroller 71 and a regulating chip 72.

[0082] The microcontroller 71 is connected to the regulating chip 72, and the regulating chip 72 is connected to the power supply circuit.

[0083] The microcontroller 71 can control the opening and closing of the regulating chip 72 and the opening duration, and can also control the regulating chip 72 to adjust the voltage value output by the power supply circuit, so that the power supply circuit can output the set voltage value through the output interface 3 within a set time.

[0084] It should be noted that the microcontroller 71 and the regulating chip 72 in this embodiment are physical structural components. Furthermore, the operation of the microcontroller 71, the regulating chip 72, and the power supply circuit follows the conventional operating principles of the microcontroller 71 and the regulating chip 72, and is a standard setup in the field. It does not involve any improvement or use of computer programs, but only provides the connection relationships between the components within the voltage regulator.

[0085] Example 3

[0086] Based on Embodiments 1 and 2, this embodiment also provides a dental drill device, which includes a voltage regulator for the dental drill, a dental drill, a high-pressure air source, and multiple branch pipes.

[0087] The main pipe of the multi-branch pipe is connected to a high-pressure gas source, and the branch pipes of the multi-branch pipe are connected to valve body 41 and the dental drill respectively. The power supply circuit is connected to the light on the dental drill through wires.

[0088] The high-pressure gas source can simultaneously supply high-pressure gas to the dental drill and valve body 41, so that the drill bit of the dental drill is driven to rotate by the internal turbine, and the voltage regulator can power the lighting of the dental drill.
