Description

Technical Field

[0001] This application relates to the field of dental medical device technology, and more specifically, to a light-curing head and a light-curing machine. Background Technology

[0002] Currently, in existing technologies, light curing machines consist of a main unit and a light curing head, both of which emit light from one side. The light curing machine is used to irradiate and cure the filling resin. Depending on the resin's sensitivity to different wavelengths, it is necessary to switch between single blue light or a blue-violet mixed light. When the microcrack detection function is required, the general operation method is to use the light curing head to output single violet light for checking cavities, or to output single white light for checking microcracks. Since treatment and detection are often performed simultaneously, doctors need to frequently switch between curing treatment mode and detection mode.

[0003] In existing technologies, the switching between solidification treatment mode and detection mode typically takes the following forms:

[0004] Option 1: The light-curing head emits blue light, blue-violet light, or other therapeutic light sources. A magnetic head light-converting (focusing) component is connected to the light outlet to convert the emitted light into white light and focus the light to form a point light source, thereby increasing the light intensity and enabling the detection mode. Because an external component is required, the outer protective cover of the device needs to be replaced during use, increasing treatment time and cost. At the same time, the external light-converting component increases the thickness of the light-curing head, which requires a larger opening angle for the patient, reducing treatment comfort.

[0005] Option 2: Arrange all light-emitting components on the same side of the light-curing head, that is, all light-emitting components are spaced apart on the same mounting surface of the light-curing head, and the host machine switches between different light sources. However, this option obviously increases the diameter of the structure used for light emission. When light-emitting components placed close to the host machine are needed for curing treatment or testing, the patient's mouth opening needs to be increased in order to align the required light-emitting components with the teeth, thereby reducing treatment comfort.

A main control board is provided at the end of the connecting cylinder away from the mounting cylinder. The mounting cylinder is the light-emitting end.

There is no need for an external magnetic head light conversion component, which is convenient for dentists to use, reduces treatment time and cost. Since there is no external light conversion component, the thickness of the light curing head will not be increased, so there is no need to increase the patient's opening angle, which improves the comfort of treatment.

[0045] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0046] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0047] This application provides a photocuring head 100, such as... Figures 1 to 5 As shown, the light curing head 100 includes: a head handle 10 and two sets of light-emitting elements 20; the head handle 10 includes a light-emitting end 11, the light-emitting end 11 is provided with two sets of light-emitting elements 20 with different light emission directions, and the two light-emitting elements 20 are located on different mounting surfaces of the light-emitting end 11; one set of light-emitting elements 20 emits a first mode light, and the other set of light-emitting elements 20 emits a second mode light, at least one of the first mode light and the second mode light is a curing treatment light, and the first mode light is different from the second mode light.

[0048] The working principle and beneficial effects of a photocuring head 100 provided in this application embodiment are as follows:

[0049] This application features two sets of light-emitting elements 20, each emitting light in a different mode. This allows dentists to switch between curing treatment modes and other modes simply by rotating the light curing head 100 and adjusting the light-emitting direction of the light-emitting elements 20, without needing to replace the external magnetic head light-conversion assembly. This makes it convenient for dentists to use, reducing treatment time and costs. Furthermore, since there is no external light-conversion assembly, the thickness of the light curing head is not increased, thus eliminating the need to increase the patient's opening angle and improving treatment comfort.

[0050] Meanwhile, the two sets of light-emitting elements 20 are located on different mounting surfaces of the light-emitting end 11. Compared with the structure of two sets of light-emitting elements spaced apart on the same mounting surface of the light-emitting end, the diameter of the entire light-emitting end 11 is reduced. Therefore, the required light-emitting elements 20 can be aligned with the teeth without increasing the patient's opening angle, thus improving the comfort of treatment.

[0051] In this embodiment, the surface of the light-emitting element 20 can be spherical or planar; the light-emitting element 20 with a spherical surface has a light-focusing function, while the light-emitting element 20 with a planar surface has a smaller thickness; different surfaces of the light-emitting element 20 can be selected according to requirements, and this application does not impose any restrictions.

[0052] Furthermore, the light-emitting end 11 is provided with two light-emitting ports 12, and the light-emitting direction of a group of light-emitting elements 20 is arranged toward one of the light-emitting ports 12. The axes of the two light-emitting ports 12 are at an angle of 30° to 330°.

[0053] In this embodiment, the included angle between the axes of the two light-emitting ports 12 can be adjusted according to actual needs, and this application does not impose any restrictions on this.

[0054] like Figure 12 As shown, further, the projection of one of the light-emitting ports 12 onto the mounting surface where the other light-emitting port 12 is located is within the other light-emitting port 12 or overlaps with the other light-emitting port 12.

[0055] Figure 12 (a) to Figure 12 In (d), the dashed line represents the projection range of the optical port 12. In this embodiment, exemplarily, Figure 12 (a) and Figure 12 In (b), the included angle between the two light outlets 12 is 180°, that is, the light emission directions of the two sets of light-emitting elements 20 are set opposite to each other; to describe the direction in the figure, the projection of the left light outlet 12 onto the mounting surface where the right light outlet 12 is located overlaps with the right light outlet 12, avoiding the situation where two light outlets 12 need to be opened and the diameter of the light-emitting end 11 needs to be increased, so that the required light-emitting element 20 can be aligned with the teeth without increasing the patient's opening angle, thus improving the comfort of treatment. Figure 12 (c) and Figure 12 In (d), the angle between the two light outlets 12 is 90°, that is, the light emission directions of the two sets of light-emitting elements 20 are set perpendicularly. To describe the direction in the figure, the projection of the left light outlet 12 onto the mounting surface where the right light outlet 12 is located is within the right light outlet 12. This avoids the situation where two light outlets 12 need to be opened and the diameter of the light-emitting end 11 needs to be increased. In this way, the required light-emitting element 20 can be aligned with the teeth without increasing the patient's opening angle, thus improving the comfort of treatment.

[0056] In addition, each set of light-emitting elements 20 is configured with a corresponding light-emitting port 12, so that the opening diameter of the light-emitting port 12 can be set according to actual needs; for example, when the first mode light is a detection light, the diameter of its corresponding light-emitting port 12 is smaller, which can reduce the divergence of its light source and improve the detection effect; or, when the first mode light is a curing treatment light, the diameter of its corresponding light-emitting port 12 is larger, so that the light source can cover the entire end face of the tooth and improve the treatment effect; of course, it is not limited to this, it is just an example.

[0057] In some embodiments, both the first mode light and the second mode light are curing therapeutic lights, and the first mode light and the second mode light have different wavelength ranges.

[0058] In this embodiment, a rotating light curing head 100 can be selected to switch between two curing treatment lights in order to improve the curing effect.

[0059] Furthermore, when both the first mode light and the second mode light are curing treatment lights, one of the curing treatment lights is blue light and the other is blue-violet light; the wavelength of the blue light is 410nm to 520nm; and the wavelength of the blue-violet light is 380nm to 520nm.

[0060] Furthermore, when both the first mode light and the second mode light are curing treatment lights, and one of the curing treatment lights is blue light and the other is blue-violet light; one set of light-emitting elements 20 includes a plurality of first LEDs (not shown), which are used to emit blue light; the other set of light-emitting elements 20 includes a plurality of second LEDs (not shown) and a plurality of third LEDs (not shown), one of the second LEDs and the third LEDs is used to emit blue light and the other is used to emit violet light; the two light outlets have the same area, and the total number of the second LEDs and the third LEDs is equal to the number of the first LEDs.

[0061] When one curing treatment light is blue light and the other is blue-violet light, in the same unit area, a certain number (e.g., n) of first LEDs emitting blue light are arranged in one light outlet 12, and a second LED emitting blue light and a third LED emitting violet light are arranged in the other light outlet 12 (the total number of the second and third LEDs is n). When curing photosensitive resin materials, the wavelength range of blue light is not wide enough, which may cause some photosensitive resin materials to fail to cure. In order to increase the wavelength range, several third LEDs emitting violet light are used to replace an equal number of second LEDs emitting blue light, resulting in a reduction in the number of second LEDs emitting blue light compared to the first LEDs emitting blue light. Since the luminous efficiency (photon count / power) of the second LEDs emitting blue light is usually higher than that of the third LEDs emitting violet light, the curing efficiency of blue-violet light will decrease. In the above embodiment, when curing photosensitive resin materials, the light curing head 100 can be rotated to switch between blue light and blue-violet light, thereby improving the curing efficiency and effect.

[0062] In some embodiments, one of the first mode light and the second mode light is a curing treatment light, and the other is a detection light.

[0063] In the above embodiments, the light curing head 100 can be rotated to switch between curing treatment light and detection light, which facilitates the doctor in curing materials and detecting teeth, and also makes it easier for the doctor to observe the curing status.

[0064] Furthermore, when one of the first mode light and the second mode light is a curing treatment light and the other is a detection light, the curing treatment light is blue light or blue-violet light, and the detection light is white light or violet light; the wavelength of the blue light is 410nm to 520nm; and the wavelength of the blue-violet light is 380nm to 520nm.

[0065] like Figure 3 As shown, further, when one of the first mode light and the second mode light is a curing treatment light and the other is a detection light, the diameter of the light outlet 12 corresponding to the light-emitting element 20 that emits the curing treatment light is greater than the diameter 12 of the light outlet corresponding to the light-emitting element 20 that emits the detection light.

[0066] The diameter of the light outlet 12 corresponding to the light-emitting element 20 that emits the curing treatment light is larger, which can increase the light-emitting area and light-emitting efficiency of the light-emitting element 20, so that the light source can cover the entire end face of the tooth and improve the treatment effect; while the diameter of the light outlet 12 corresponding to the light-emitting element 20 that emits the detection light is smaller, which can prevent the light emitted by the light-emitting element 20 from scattering and improve the detection effect.

[0067] In some embodiments, one of the first mode light and the second mode light is a curative treatment light, and the other is selected from a laser.

[0068] In the above embodiments, a rotating light curing head 100 can be selected to switch between curing light and laser, so that doctors can cure materials and treat teeth.

[0069] Furthermore, when one of the first mode light and the second mode light is a curing treatment light and the other is selected from a laser, the curing treatment light is blue light or blue-violet light; the wavelength of the blue light is 410nm to 520nm; and the wavelength of the blue-violet light is 380nm to 520nm.

[0070] like Figures 1 to 5 As shown, the head handle 10 further includes a head housing 13 and a head cover 14. The head housing 13 includes an integrally formed connecting cylinder 131 and a mounting cylinder 132 that are perpendicular to each other. The end of the connecting cylinder 131 away from the mounting cylinder 132 is provided with a main control board 15. The mounting cylinder 132 is the light-emitting end 11. Two sets of light-emitting elements 20 are disposed inside the mounting cylinder 132. The side wall of the mounting cylinder 132 is provided with a connecting hole 133 that communicates with the connecting cylinder 131. Two light-emitting ports 12 are respectively disposed at both ends of the mounting cylinder 132, or one light-emitting port is disposed at the end of the mounting cylinder 132 and the other light-emitting port is disposed at the side wall of the mounting cylinder 132. The head cover 14 is connected to one of the light-emitting ports 12. The two sets of light-emitting elements 20 are electrically connected to the main control board 15.

[0071] In this embodiment, the connecting cylinder 131 is provided with a connecting hole 133 so that the electrical wiring between the two light-emitting elements 20 and the main control board 15 can pass through; the doctor sends an external signal to the main control board 15 through the host 200 to turn the two light-emitting elements 20 on or off, and the main control board 15 controls the two light-emitting elements 20 according to the external signal.

[0072] Preferably, the two light outlets 12 are respectively located at both ends of the mounting cylinder 132.

[0073] Furthermore, the outer wall of the head cover 14 is threadedly connected to the inner wall of the mounting cylinder 132 to facilitate disassembly and assembly.

[0074] like Figure 3 As shown, the photocuring head 100 further includes a first light-concentrating element 30 and a convex lens 40. The first light-concentrating element 30 is disposed on the light-emitting element 20 near the head cover 14, and the convex lens 40 is disposed between the head cover 14 and the first light-concentrating element 30.

[0075] In this embodiment, the light emitted by the light-emitting element 20 located near the head cover 14 is focused by the first light-concentrating cup and then enters the convex lens 40. The convex lens 40 diffuses the light source and emits it, thereby increasing the illumination range.

[0076] Furthermore, the inner wall of the head cover 14 is provided with a first limiting ring 141, and the convex lens 40 is disposed between the first limiting ring 141 and the first focusing element 30; this can prevent the convex lens 40 from falling off and improve the sealing performance of the photocuring head 100.

[0077] Furthermore, a first sealing buffer ring 16 is provided between the head cover 14 and the mounting cylinder 132; and / or, a second sealing buffer ring 17 is provided between the convex lens 40 and the first focusing element 30.

[0078] In this embodiment, a first sealing buffer ring 16 and / or a second sealing buffer ring 17 are provided to improve the sealing performance of the photocuring head; and to protect the first condenser cup from being damaged by impact.

[0079] like Figure 3 As shown, in some embodiments, the photocuring head 100 further includes a second focusing cup 50, which covers the light-emitting element 20 away from the head cover 14 and abuts against the inner wall of the mounting cylinder 132.

[0080] In the above embodiment, the light emitted by the light-emitting element 20, which is located away from the head cover 14, is emitted after passing through the second light-concentrating cup 50, thus achieving point light source illumination.

[0081] Furthermore, a second limiting ring 134 is provided on the inner wall of the end of the mounting cylinder 132 away from the head cover 14, and the second focusing cup 50 is disposed between the second limiting ring 134 and the mounting cylinder 132; this can prevent the second focusing cup 50 from falling off and improve the sealing performance of the light curing head 100.

[0082] Furthermore, a third sealing buffer ring 18 is provided between the mounting cylinder 132 and the second focusing cup 50.

[0083] In this embodiment, a third sealing buffer ring 18 is provided to improve the sealing performance of the photocuring head; and to protect the second condenser cup 50 from being damaged by impact.

[0084] like Figures 6 to 8 As shown, in some embodiments, the mounting cylinder 132 has a receiving groove 135 at the end away from the head cover 14, and the light curing head 100 also includes a light-transmitting sheet 60, which is disposed in the receiving groove 135.

[0085] Since the light-concentrating element has a certain thickness in order to achieve the light-concentrating effect; in the above embodiment, the light-emitting element 20, which is located away from the head cover 14, emits light through the light-transmitting sheet 60, so there is no need to set up a light-concentrating element, which can reduce the overall thickness of the light curing head 100.

[0086] like Figure 1 , Figures 9 to 11 As shown, the photocuring head 100 further includes a light source control board 70, and the two sets of light-emitting elements 20 are integrated on both sides of the light source control board 70; or, the photocuring head 100 includes two light source control boards 70, and a set of light-emitting elements 20 are integrated on one light source control board 70.

[0087] The light source control board 70 is disposed inside the connecting cylinder 131 and the mounting cylinder 132. The light source control board 70 is electrically connected to the main control board 15. The two sets of light-emitting elements 20 are located inside the mounting cylinder 132. The main control board 15 integrates a control module, and the light source control board 70 also integrates a communication module. The communication module is used to receive control signals sent by the control module to control the switching of the light-emitting elements 20.

[0088] In this embodiment, the doctor sends an external signal to the control module of the main control board 15 to turn on or off via the host 200 or operating software. The control module sends a control signal to the communication module based on the external signal. After receiving the control signal, the communication module controls the light-emitting element 20 to turn on or off.

[0089] Preferably, the photocuring head 100 further includes a light source control board 70, and the two sets of light-emitting elements 20 are integrated on both sides of the light source control board 70.

[0090] In this embodiment, the two sets of light-emitting elements 20 are integrated on a light source control board 70, which reduces the structure of the light curing head 100, thereby reducing the space inside the head handle 10 for installing various components, and further reducing the overall thickness of the light curing head 100. This eliminates the need to increase the patient's opening angle and improves the comfort of treatment.

[0091] In this embodiment, when the two sets of light-emitting elements 20 are integrated onto one of the light source control boards 70, only one processing of the light source control board 70 is required. When the two sets of light-emitting elements 20 are integrated onto one light source control board 70, a second processing of the light source control board 70 is required. The yield of the first processing is higher than that of the second processing, thereby reducing the loss rate of the light source control board 70 during the two processing processes.
