[0028] Reference Figures 1 to 4 The present invention provides a high-efficiency self-illuminating dental handpiece, which is embodied in the following embodiment:

[0029] A high-efficiency self-illuminating dental handpiece includes a head 100, a handle 200, and a quick connector 300. The head 100 is fixedly attached to one end of the handle 200, and the quick connector 300 is inserted into the other end of the handle 200. A self-generating power unit 330 is housed within the quick connector 300. A light 210 is located at the end of the handle 200 near the head 100. When the handle 200 and the quick connector 300 are connected, an electrical connection is established, directly transmitting the power generated by the quick connector 300 to the light 210. In use, the quick connector 300 is connected to an external air source. Airflow passes through the self-generating power unit 330, driving it to generate electricity, which is then supplied to the light 210. The traditional method involves directly placing the lighting lamp 210 at the quick connector 300 and transmitting the light through optical fiber, resulting in a loss of light efficiency. This application, however, places the self-generating component 330 within the quick connector 300, but directly conducts the electricity from the quick connector 300 to power the lighting lamp 210 on the handle 200, thus improving luminous efficiency compared to the traditional quick connector 300. Furthermore, during cleaning and disinfection, the quick connector 300 can be removed, allowing direct cleaning of the dental head 100 and handle 200. Since the self-generating component 330 is located within the quick connector 300, it does not need to be cleaned and disinfected along with the dental head 100, thereby extending its lifespan.

[0030] Specifically, one end of the handle 200 is fixedly equipped with a handpiece head 100, which is fitted with a needle. The other end of the handle 200 is provided with a insertion slot 250 for insertion into a quick connector 300. A light 210 is provided near the end of the handpiece head 100, and the light 210 is embedded in the handle 200. The outer surface of the light 210 is flush with the outer wall of the handle 200. In some other embodiments, the light 210 may protrude from the surface of the handle 200, depending on the specific situation. When the light 210 is embedded in the handle 200, it reduces the space occupied by the dentist during operation, which helps improve the flexibility and precision of the operation. Especially during delicate dental treatments, such as tooth restoration and root canal treatment, dentists need to concentrate highly and precisely control the movement of the dental handpiece; reducing the size of the handle 200 reduces the difficulty of the operation. Secondly, the light 210 embedded in the handle 200 improves the overall shape and appearance of the handle 200.

[0031] The handle 200 is provided with an air inlet pipe 220, an exhaust pipe 230, and a water inlet pipe. In some other embodiments, an atomizing pipe is also provided. One end of the air inlet pipe 220, the exhaust pipe 230, and the water inlet pipe are all connected to the head 100. The other end of the atomizing pipe, the air inlet pipe 220, the exhaust pipe 230, and the water inlet pipe are fixed to the inner side wall of the insertion slot 250, so as to facilitate corresponding connection with various channels of the quick connector 300.

[0032] The quick connector 300 has a plug-in end 310 and a connecting end 320 at both ends. The plug-in end 310 is plugged into the plug-in slot 250. The connecting end 320 is provided with an air inlet connector 321, a water connector 322 and an air return connector 323. The quick connector 300 is provided with an air inlet channel 340, an air return channel 350 and a water inlet channel. When the quick connector 300 is plugged into the handle 200, the air inlet connector 321 is connected to the air inlet pipe 220 through the air inlet channel 340, the air return connector 323 is connected to the exhaust pipe 230 through the air return channel 350, and the water connector 322 is connected to the water inlet pipe through the water inlet channel.

[0033] The quick connector 300 includes a self-generating component 330, which has a power generation unit. The plug end 310 has a second electrical connector 311. The first electrical connector 260 and the second electrical connector 311 are interlocked to improve connection stability and create a tighter, more reliable contact between the conductive contacts of the first electrical connector 260 and the second electrical connector 311. This tight contact reduces contact resistance, minimizes energy loss during power transmission, and improves the efficiency of the electrical system.

[0034] Specifically, the first electrical connector 260 has a first end and a second end at its two ends. The first end has two electrical terminals, which are electrically connected to the lighting lamp 210 via a wire 360. The second end has an electrical slot 261, and the second electrical connector 311 has an electrical plug 3111 that is inserted into the electrical slot 261. In some other embodiments, the second end has an electrical plug 3111, and the second electrical connector 311 has an electrical slot 261 that is inserted into the electrical plug. Of course, since the insertion end 310 is inserted into the insertion slot 250, direct electrical contact between the first electrical connector 260 and the second electrical connector 311 can also ensure the stability of the conductive contact and the electrical connection effect to a certain extent. Therefore, direct electrical contact between the first electrical connector 260 and the second electrical connector 311 is also used in some other embodiments.

[0035] The power generation component is electrically connected to the second electrical connector 311. The return air channel 350 passes through the self-generating component 330 and drives the power generation unit to work through airflow. The self-generating component 330 is described in detail below.

[0036] The quick connector 300 has a receiving cavity. The self-generating component 330 is prior art and is not explicitly shown in the drawings. The self-generating component 330 includes a first housing portion with a first inner cavity. The first housing portion communicates with a return channel, through which airflow returning from the handle 200 is injected into the first inner cavity. A second housing portion is provided within the first inner cavity, with a gap between the first and second housing portions, which can be understood as part of the return channel. The second housing portion has a second inner cavity and at least one through hole to connect the first and second inner cavities. The second inner cavity communicates with the return connector and has a rotatable fan. A magnetic rod is connected to the fan, and the magnetic rod and the fan's axis are coaxial. A coil surrounds the outer periphery of the magnetic rod. The coil is electrically connected to a first conductive terminal. The self-generating component 330 is provided with a power socket, and the power socket is provided with a second conductive terminal. The second conductive terminal and the first conductive terminal are male and female to each other and are connected to each other. The second conductive terminal is connected to the second electrical connector 311 by a wire 360.

[0037] Through the above structure, the driving airflow introduced from outside the mobile phone enters the head unit 100 through the air inlet connector 321 and drives the head unit 100, then... Figure 4 The airflow is injected into the power generation component through the return channel. The airflow passes through the gap between the first and second housings and is injected into the second inner cavity through the through hole, thereby driving the fan to rotate. The magnet rod is synchronously driven by the fan, forming an electromagnetic interaction with the coil, thereby generating electricity, which is then transmitted to the light-emitting device for use through the first conductive terminal, the second conductive terminal, and the wire 360.

[0038] In some other embodiments, the fan of the power generation component may also be driven to generate electricity by the airflow through the air intake passage 340.

[0039] Furthermore, to improve the connection effect between the quick connector 300 and the handle 200, four sealing rings 312 are sleeved on the outer peripheral wall of the plug end 310. The four sealing rings 312 are spaced apart along the axial direction of the quick connector 300. The sealing rings 312 are rubber rings and serve as limiting sealing rings 312. Multiple annular grooves 313 are provided on the outer peripheral wall of the plug end 310. The multiple annular grooves 313 are spaced apart along the axial direction of the quick connector 300, and the multiple sealing rings 312 are correspondingly engaged with the multiple annular grooves 313. The connection ports of the air inlet channel 340, the air return channel 350, and the water inlet channel to the handle 200 are all located on the outer peripheral wall of the plug end 310. One of the connection ports is provided between two adjacent sealing rings 312. The sealing rings 312 can improve the sealing effect and prevent leakage between the various channels.

[0040] Furthermore, the handle 200 is also provided with an atomizing tube connected to the head 100, the quick connector 300 is provided with an atomizing channel, the connecting end 320 is provided with an atomizing connector 324, the atomizing connector 324 is connected to the atomizing tube through the atomizing channel, and the atomizing gas connector is connected to the outside through an external atomizing channel to increase the atomizing function.

[0041] Furthermore, the quick connector 300 is provided with a wire 360 ​​for connecting to an external power source. The wire 360 ​​is connected to the second electrical connector 311 and can directly illuminate the lighting lamp 210 through an external power source.

[0042] In a further improvement, the machine head 100 is equipped with a bur, the extension path of which intersects at a single point with the main illumination direction of the lamp 210. When the extension of the bur intersects with the main illumination direction of the lamp 210, the light from the lamp 210 can be precisely focused on the area where the bur will be operated. The dentist can see the details and lesions on the tooth surface more clearly, thus performing the operation more precisely and reducing damage to surrounding healthy tissues.

[0043] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
