Description
Technical Field
[0001] The utility model belongs to the field of oral photography, and particularly relates to an anti-fog flash for an oral camera. Background Art
[0002] For digital oral photography and taking intraoral photos of teeth, a reflector must be used. When the reflector is placed in the mouth, fog often appears because its temperature is lower than that of the oral cavity, which affects the photo quality and makes it unusable. Currently, for professional oral photos, intraoral photos are taken while using a single-lens reflex camera and cooperating with a ring flash in front of the lens, without a defogging function.
[0003] The following are several conventional defogging methods:
[0004] 1. Preheat the reflector in advance so that its temperature is relatively high before putting it into the mouth. However, a high temperature also has a risk of scalding the mucous membrane, and fog is likely to appear after the temperature drops after a long time.
[0005] 2. Add heating wires and air outlets on the reflector to remove fog. The overall reflector device is relatively large and thick, and the size is fixed, which cannot meet the needs of different oral sizes and dentition sizes.
[0006] 3. Use a hair dryer or an air gun to blow air separately. Extra personnel must cooperate to hold the hair dryer or the air gun. Moreover, if the air volume of the hair dryer is too large, it often causes discomfort and nausea in the patient's mouth when the patient opens the mouth wide.
[0007] The existing defogging methods usually heat up the reflector or hold a hair dryer. The above methods are difficult to stably remove fog and often cause discomfort in the patient's mouth.
[0008] Therefore, those skilled in the art have proposed an anti-fog flash for an oral camera to solve the problems raised in the background art. Content of the Utility Model
[0009] In order to solve the above technical problems, the utility model provides an anti-fog flash for an oral camera to solve the problems that the existing defogging methods usually heat up the reflector or hold a hair dryer, the above methods are difficult to stably remove fog, and often cause discomfort in the patient's mouth.

[0012] Through the above technical solution, by setting a micro motor and a fan blade, after being controlled by a control board, the fan blade is quickly driven to blow air from the ventilation slot, so as to quickly blow and defog the reflector. This method can be manually controlled by a controller, greatly improving the flexibility of defogging, ensuring the stable progress of oral photography, and avoiding discomfort to patients at the same time.
[0013] Preferably, the ventilation slot is of an arc-shaped groove structure. Air outlets are provided at both ends of the ventilation slot, and air inlets are provided on the peripheral side of the ventilation slot. The air inlets are located above the housing.
[0014] Through the above technical solution, by providing air outlets at both ends of the ventilation slot, the air outlet range is ensured, avoiding too small air outlets, and defogging the reflector in a larger range.
[0015] Preferably, the controller is built-in with a power supply. A connecting wire is provided between the controller and the control board, and the control board is electrically connected to the micro motor.
[0016] Through the above technical solution, the controller can manually and flexibly control the start of the micro motor. Preferably, a plurality of auxiliary lights are further provided on the front end face of the housing, and the auxiliary lights are electrically connected to the control board.
[0017] Through the above technical solution, the control board can set the start of the auxiliary lights. The auxiliary lights are focusing lights. When the camera takes a picture and focuses, the micro motor is automatically started to blow air and defog the reflector.
[0018] Preferably, guiding parts are provided at both ends of the ventilation slot.
[0019] Through the above technical solution, the guiding parts enable stable ventilation in the ventilation slot and ensure the output of wind power.
[0020] Preferably, a holding part is installed on the peripheral side of the housing.
[0021] Preferably, a connecting ring is fixedly installed on the inner wall of the housing.
[0022] Preferably, the number of lamp heads is four groups, and the lamp heads are symmetrically distributed on both sides of the air outlet.
[0023] Through the above technical solution, by providing multiple groups of lamp heads, the illumination range of the flash lamp is ensured.
[0024] Compared with the prior art, the present utility model has the following beneficial effects:
[0025] The utility model can effectively remove the fog generated during the use of the flash by setting ventilation slots, a micro motor and a fan blade. Through active air circulation, the fog can be quickly eliminated, ensuring the clarity and accuracy of shooting. The ventilation slots, the air outlets and inlets at both ends can more evenly guide the air flow and improve the defogging efficiency. In the humid oral cavity, this uniform air flow distribution can quickly remove the water vapor on the surface of the lamp head, avoiding local fog residue. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following further describes in detail the embodiments of the utility model with reference to the drawings and embodiments. The following embodiments are used to illustrate the utility model, but cannot be used to limit the scope of the utility model.
[0034] Embodiment 1: As shown in Figure 1 to Figure 5 : The utility model provides an anti-fog flash for an oral camera, including a housing 1 and a controller 4. A plurality of lamp heads 2 are arranged on the front end face of the housing 1, and a defogging component is arranged on the housing 1;
[0035] The defogging component includes a ventilation slot 8 opened in the housing 1, a control board 9 installed in the ventilation slot 8, a positioning frame 12 installed at the air outlet 11 in the ventilation slot 8, a micro motor 13 installed at the positioning frame 12, and a fan blade 14 installed at the output end of the micro motor 13;
[0036] The ventilation groove 8 is of an arc-shaped groove structure. Air outlet openings 11 are provided at both ends of the ventilation groove 8, and air inlet openings 10 are provided on the circumferential side of the ventilation groove 8. The air inlet openings 10 are located above the housing 1, and guiding portions 15 are provided at both ends of the ventilation groove 8.
[0037] The controller 4 has a built-in power supply. A connecting wire 5 is provided between the controller 4 and the control board 9. The control board 9 is electrically connected to the micro motor 13. The power supply provides independent and stable power support for the flash lamp and the defogging component, without being restricted by an external power supply, which is convenient for use in different scenarios; during mobile medical examinations, shooting can be carried out at any time without searching for a power socket; the setting of the control board 9 and its electrical connection with each component achieve centralized control of the lamp head 2, the auxiliary lamp 3 and the defogging component, improving the operation convenience and the degree of intelligence of the device, and the brightness of the light and the intensity of defogging can be flexibly adjusted according to different shooting requirements.
[0038] A plurality of auxiliary lamps 3 are further provided on the front end face of the housing 1. The auxiliary lamps 3 are electrically connected to the control board 9. The auxiliary lamps 3 are camera auxiliary focusing lamps. When the camera recognizes fog on the reflector during the focusing process, the control board 9 is started through control, and the controller 4 quickly responds to control the micro motor 13 to blow air; the controller 4 is data-connected to the camera through a wiring head; by providing a plurality of lamp heads 2 and auxiliary lamps 3, sufficient and uniform illumination can be provided, enabling the details inside the oral cavity to be clearly presented; when taking a photo, pressing the shutter control allows a photographer to complete the intraoral photo shooting alone without the cooperation of additional personnel, enhancing the user experience;
[0039] As can be seen from the above, due to the differences in temperature and humidity, the flash lamp is prone to fogging, which affects the shooting effect. The controller 4 can control the defogging component to turn on. The micro motor 13 drives the fan blade 14 to rotate rapidly, and a negative pressure is quickly formed at the air outlet opening 11. Cooperating with the ventilation groove 8, an air flow is quickly blown out at the air outlet opening 11. In the oral cavity environment, through active air circulation, the fog is quickly eliminated, ensuring the clarity and accuracy of shooting.
[0040] After the camera focuses and the shutter is pressed to activate the flash lamp, the flash lamp automatically turns off. The defogging component prevents the reflector from overheating and scalding the oral mucosa, and also prevents the reflector from being too large or too thick and causing discomfort when placed in the oral cavity; an ordinary reflector can also be used for immersion high-temperature disinfection to avoid problems such as poor disinfection; at the same time, when taking a photo, pressing the shutter control allows a photographer to complete the intraoral photo shooting alone without the cooperation of additional personnel, enhancing the user experience
[0041] Embodiment 2: On the basis of Embodiment 1, a holding part 6 is installed on the peripheral side of the housing 1, and a connecting ring 7 is fixedly installed on the inner wall of the housing 1; the holding part 6 facilitates the user to hold stably, making the operation more accurate and comfortable, reducing shooting mistakes caused by unstable hands. During the long-term oral cavity shooting process, a comfortable holding part can relieve the user's hand fatigue; the connecting ring 7 helps to stably install and connect internal components, enhancing the overall stability and reliability of the device.
[0042] The number of the lamp heads 2 is four groups, and the lamp heads 2 are symmetrically distributed on both sides of the air outlet 11.
[0043] As can be seen from the above, the lamp heads 2 are symmetrically distributed on both sides of the air outlet 11, which helps to avoid uneven illumination and improve the shooting quality; when shooting fine cracks or diseased parts of teeth, uniform and sufficient light can capture details more accurately.
[0044] The connecting ring 7 enables the flash lamp to be snap-connected with various oral cavity macro lenses, providing convenience for subsequent equipment maintenance and component replacement, reducing maintenance costs and time; it helps to keep the internal structure of the device compact, saves space, and reserves the possibility for possible technical upgrades and function expansions.
