[0002] During use, the dental light curing machine needs to be equipped with a light guide rod to obtain the ideal light intensity. The light source fully irradiates the filled photosensitive curing composite resin, causing it to cure quickly and shortening the irradiation time.

[0003] Currently, the commonly used light curing machines in dentistry are halogen light curing machines and LED light curing machines. During treatment, the power is turned on, the light guide rod is installed on the light curing machine, the switch is manually triggered, the host outputs voltage, the light source bulb emits light, and after being filtered by the interference filter, the light guide rod transmits the effective light to the treatment site. However, in actual use, the light guide rod is often not installed or installed poorly. After the user triggers the light source switch, the strong light directly shines on the human eye without passing through the light guide rod, which can cause irreversible damage. Utility Model Content

[0004] The utility model aims to provide a light guide rod installation structure with high safety and a dental light curing machine, so as to prevent damage to human eyes caused by failure to install or improper installation of the light guide rod.

[0005] In order to achieve the above-mentioned purpose, the present application provides a light guide rod installation structure: a light guide rod, a positioning assembly and a circuit board, the light guide rod includes a mounting portion and an optical fiber rod arranged on the mounting portion, the mounting portion has a first magnetic adsorption component, the positioning assembly includes a positioning frame and a Hall sensor, the positioning frame has a mounting position, and the positioning frame is provided with a second magnetic adsorption component that cooperates with the first magnetic adsorption component for adsorption, the mounting portion is detachably connected to the mounting position, the Hall sensor is arranged on the positioning frame for sensing changes in magnetic flux, and the Hall sensor is electrically connected to the circuit board.

[0006] As a preferred technical solution, the mounting portion is a ferromagnetic part, the mounting portion is limited to form the first magnetic adsorption part, and the second magnetic adsorption part is a magnet installed on the positioning frame.

[0007] As a preferred technical solution, the installation position is a slot opened at one end of the positioning frame, and the installation part is plugged into the slot.

[0008] As a preferred technical solution, the first magnetic adsorption component is arranged around the outer periphery of the mounting portion, and the Hall sensor is located on the outer periphery of the positioning frame.

[0009] As a preferred technical solution, the mounting portion includes: an insertion portion and a limiting portion connected in sequence, the insertion portion is inserted into the slot, the limiting portion is limited by the end face of the positioning frame, and the optical fiber rod is installed at one end of the limiting portion away from the insertion portion.

[0010] As a preferred technical solution, the circuit board is mounted on the positioning frame.

[0011] As a preferred technical solution, the circuit board is mounted on an end of the positioning frame away from the light guide rod.

[0012] In addition, the utility model also provides a dental light curing machine, including: a light curing machine body, a light source switch, a control component and the light guide rod installation structure as described above, the light source switch is electrically connected to the control component, the positioning frame is installed on the light curing machine body, and the circuit board is electrically connected to the control component.

[0013] The light guide rod installation structure and the dental light curing machine equipped with the installation structure provided by the above technical solution have the following beneficial effects compared with the prior art:

[0014] The first and second magnetic adsorption parts that can cooperate with adsorption are respectively installed on the light guide rod and the positioning component. At the same time, a Hall sensor is arranged on the positioning component. During the installation of the light guide rod, the position between the first and second magnetic adsorption parts changes, which causes the magnetic field between the two magnetic adsorption parts to change, and the Hall sensor can sense the magnetic field change. When the light guide rod is installed on the positioning component, the Hall sensor transmits the sensed magnetic flux signal to the circuit board, and the circuit board transmits the signal to the control component. The control component determines whether the light guide rod is inserted according to the current signal. When it is determined that the light guide rod is installed, the light source switch is in effect, and the light curing is turned on. The light can be emitted when the light is turned on, otherwise the light source switch is in a prohibited state, and no light is emitted when the light curing machine switch is turned on; based on this, it can effectively prevent the user from accidentally touching the light source switch when using the light curing machine. Instead, after the Hall sensor detects the magnetic flux, the control component determines whether the light guide rod is installed, and the control component controls the light source switch to be in an effective or prohibited state according to the signal detected by the Hall sensor, which can prevent the strong light inside the device from being directly emitted without passing through the light guide rod, causing irreversible damage to the human eye; in addition, the magnetic adsorption effect between the first magnetic adsorption component and the second magnetic adsorption component can also better fix the light guide rod in the positioning component, so that the light guide rod is not easy to fall off.

[0024] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] See also Figure 1-2 , a light guide rod installation structure provided in an embodiment of the present application, includes: a light guide rod 1, a positioning assembly 2 and a circuit board 214, the light guide rod 1 includes a mounting portion 12 and an optical fiber rod 11 arranged on the mounting portion 12, the mounting portion 12 has a first magnetic adsorption component 123, the positioning assembly 2 includes a positioning frame 21 and a Hall sensor 22, the positioning frame 21 has a mounting position 211, and the positioning frame 21 is provided with a second magnetic adsorption component 213 that cooperates with the first magnetic adsorption component 123 to be adsorbed, the mounting portion 12 is detachably connected to the mounting position 211, the Hall sensor 22 is arranged on the positioning frame 21, and is used to sense changes in magnetic flux, and the Hall sensor 22 is electrically connected to the circuit board 214.

[0026] Another aspect of the embodiment of the present application further provides a dental light curing machine (not specifically shown in the drawings), which includes: a light curing machine body, a light source switch, a control component and the aforementioned light guide rod mounting structure, the light source switch is electrically connected to the control component, the positioning frame 21 is installed on the light curing machine body, and the circuit board 214 is electrically connected to the control component.

[0027] When the user needs to use the light curing machine, the light guide rod 1 needs to be installed in the positioning component 2 first, and then the switch of the light curing machine needs to be turned on for irradiation; based on the above structure, the magnetic flux values ​​a and b need to be preset in the control component first; Figure 2 As shown, at this time, the light guide rod 1 is not installed on the positioning component 2, and the magnetic flux sensed by the Hall sensor 22 is a; in the process of installing the light guide rod 1, as the first magnetic adsorption component 123 gradually approaches the second magnetic adsorption component 213, the distribution of magnetic flux lines between the first magnetic adsorption component 123 and the second magnetic adsorption component 213 will change, so that the magnetic flux sensed on the Hall sensor 22 will change, and when the light guide rod 1 is connected with the mounting position 211 through the mounting portion 12 thereon, the installation of the light guide rod 1 is completed, as shown in FIG. Figure 1 As shown, at this time, the magnetic flux value of the Hall sensor 22 collected by the control component is b.

[0028] Based on this, the present application can effectively determine whether the light guide rod 1 is installed, and based on this, can control whether the light source switch is in an effective state, thereby preventing the user from accidentally touching the light curing machine switch when using the light curing machine when the light guide rod 1 is not installed or is not installed properly, causing the strong light inside the device to be directly emitted, causing irreversible damage to the human eye; in addition, the magnetic adsorption effect between the first magnetic adsorption component 123 and the second magnetic adsorption component 213 can also better fix the light guide rod 1 in the positioning assembly 2, so that the light guide rod 1 is not easy to fall off.

[0029] See also Figure 2 In this embodiment, the mounting portion 12 is a ferromagnetic part, and the mounting portion 12 is limited to form the first magnetic adsorption component 123, and the second magnetic adsorption component 213 is a magnet installed on the positioning frame 21, so as to ensure that when the first magnetic adsorption component 123 enters the second magnetic adsorption component 213, the magnetic field at the Hall sensor 22 changes.

[0030] As an alternative, the first magnetic attraction component 123 may be set as a ferromagnetic component, and the second magnetic attraction component 213 may be set as a magnet; or, both the first magnetic attraction component 123 and the second magnetic attraction component 213 may be set as magnets.

[0031] Furthermore, the installation position 211 is a slot 212 opened at one end of the positioning frame 21, and the installation portion 12 is plugged into the slot 212; the installation form is set to be plug-in, which can make the installation simple and easy to position.

[0032] Furthermore, the first magnetic adsorption component 123 is arranged around the periphery of the mounting portion 12, and the Hall sensor 22 is located at the periphery of the positioning frame 21; the first magnetic adsorption component 123 follows the mounting portion 12 to enter the magnetic field formed by the second magnetic adsorption component 213, so that the magnetic field changes. At this time, the Hall sensor 22 located at the periphery of the positioning frame 21 senses the change in the magnetic field on one side of the second magnetic adsorption component 213, and transmits the sensed magnetic flux to the circuit board 214, and then the circuit board 214 transmits the signal to the control component. During the whole process, the positions of the Hall sensor 22 and the second magnetic adsorption component 213 are fixed, so that the Hall sensor 22 can sense the magnetic field emitted by the second magnetic adsorption component 213 in real time, and the sensing is more sensitive.

[0033] Furthermore, the mounting portion 12 includes: an insertion portion 122 and a limiting portion 121 connected in sequence, the insertion portion 122 is inserted into the slot 212, the limiting portion and the end face of the positioning frame 21 cooperate to limit, and the optical fiber rod 11 is installed at the end of the limiting portion 121 away from the insertion portion 122; the insertion portion 122 and the limiting portion 121 together constitute the mounting portion 12 inserted into the slot 212, and the setting of the limiting portion 121 ensures that the insertion portion 122 is in full contact with the slot 212, that is, it ensures that the light guide rod 1 is in full contact with the positioning assembly 2, thereby avoiding the device from being unable to start due to poor installation of the light guide rod 1, and the light in the device cannot be emitted to irradiate the treatment site.

[0034] Furthermore, the circuit board 214 is mounted on the positioning frame 21; the signal sensed by the Hall sensor 22 is transmitted to the control component through the circuit board 214, thereby improving the integration of the circuit and reducing the volume and weight of the circuit.

[0035] Furthermore, the circuit board 214 is installed on one end of the positioning frame 21 away from the light guide rod 1; the circuit board 214 is installed away from one end of the light guide rod 1, that is, the circuit board 214 is away from the first magnetic adsorption component 123 on the light guide rod 1, so as to avoid the first magnetic adsorption component 123 generating magnetic field interference on the circuit board 214, causing circuit failure and interfering with the normal operation of the equipment.

[0036] In summary, the present embodiment provides a light guide rod installation structure and a dental light curing machine. The structure detects the change in magnetic flux through a Hall sensor to determine whether the light guide rod is installed. When the light guide rod is installed, the light source switch can be controlled to take effect, thereby preventing the user from accidentally touching the light curing machine switch when using the light curing machine, causing strong light to be directly emitted without being transmitted by the light guide rod, causing irreversible damage to the human eye. If the light guide rod is not installed properly before use, or during use, the user unplugs the light guide rod 1 or the light guide rod 1 becomes loose, the light source switch can be controlled to be in a prohibited use state, thereby protecting the human eye. In addition, the light guide rod is installed on the light curing machine body by magnetic adsorption, and the installation is stable and reliable.
