When wearing the protective mask, the doctor can turn the head Hoop 8 to a suitable angle to get the best wearing feeling;

The adjustable lens 4 is arranged on the outer surface of the protective plate 3, and is formed by stacking the anti-red light lens and the anti-blue light lens side by side. Two sides of the adjustable lens 4 are respectively connected with a rack 12, and the rack 12 is vertically slidable in the slideways 2 on both sides of the protective plate 3 (see FIG. 4 );

Two motors 9 are arranged near the slideways 2 on both sides of the protective plate 3, and are connected by lines to be able to run synchronously. Each motor 9 is connected with a gear (not shown), two gears and two racks. 12 are meshed and connected respectively; in this way, when the two motors 9 run synchronously, the adjustable lens 4 can be driven to move up or down in translation, so as to control the anti-red light lens or the anti-blue light lens to adapt to the doctor's eye position;

In order to prevent fogging from the outside of the protective plate 3 , an arc-shaped air blowing pipeline 1 is fixed on the outer surface of the protective plate 3 , and there is still a space between the air blowing pipeline 1 and the protective plate 3 . There is a gap to allow the adjustable lens 4 to pass through the gap without affecting the up and down sliding of the adjustable lens 4; the air blowing line 1 has an air flow channel arranged along the length direction, and the air blowing line 1 has an air flow channel. Both ends are provided with an air inlet that communicates with the airflow channel, and each of the air inlets is provided with an air supply fan 6 blowing toward the air inlet, between the two ends of the air blowing pipe 1 A plurality of downward blowing holes are arranged (see Fig. 5 ), and the blowing holes are all communicated with the air flow channel;

In order to prevent fogging inside the protective plate 3, a cooling fan 11 capable of blowing air downward is fixed on the inner surface of the protective plate 3 at a position corresponding to the forehead of the human body;

The motor 9, the air supply fan 6 and the cooling fan 11 are all connected with a battery 10, and the battery 10 is fixed on the protective plate 3; in an alternative technical solution, the motor 9, the air supply fan 6 and the cooling fan 11 can be connected to the external power supply outside the protective mask through the power supply line.

In addition, a reflecting lens 5 protrudes outward from both sides of the protective plate 3. The reflecting lens 5 and the protective plate 3 are connected by a universal joint, so that the reflection angle of the reflecting mirror can be flexibly adjusted .

Moreover, the lower edge of the protective plate 3 is also convex and rolled to form a groove 7, and one or two suction pipes (not shown) are arranged in the groove 7. The suction port of the suction pipe Arranged at the lower part of the groove 7, the suction pipe extends upward along the groove 7 and is connected to the suction pump outside the protective mask.

Before starting work, the dentist should first adjust the tightness of the headband 8 according to the size of the head, then wear the protective mask on the head, and then adjust the angle of the protective plate 3 according to personal habits to obtain the best visual sense. In order to prevent the mist generated by the dentist from breathing for a long time from adhering to the inner surface of the protective plate 3, the dentist should start the cooling fan 11 before diagnosing and treating the patient, so that the inner surface of the mask can always be kept clean, the line of sight is clear, and at the same time It can also reduce the temperature of the dentist's face, making the working environment of the dentist more comfortable.

When a stomatologist treats a patient, he must first perform an oral examination on the patient, do some pretreatment, and then design a treatment plan according to the patient's specific situation.

In the process of cavity preparation, the dentist needs to use a high-speed eddy drill and a sharp digging spoon to clean the softened dentin in the cavity. The existence of the protective plate 3 can prevent the dirt from splashing on the doctor's face and prevent cross infection. However, these impurities will adhere to the protective plate 3 and affect the doctor's vision of operation. At this time, it is necessary to open the air barrier: open the air supply fan 6, and the air supply area of the air supply fan 6 should be larger than the air inlet of the air blowing pipe 1. In this way, part of the airflow enters the blowing pipe 1 and is ejected through the blowing holes, and the other part is ejected from the rear of the protective plate 3 to the front under the action of the blower fan 6. The gas flow is shown in Figure 4. Part of the water vapor passing through the air barrier will be blown into the groove 7 at the lower part of the protective plate 3, and because the protective plate 3 is inclined downward, the impurities on the protective plate 3 will also flow into the groove 7 along the curved surface, Finally, it is guided to the outside through the suction tube in the groove 7, so as to prevent impurities from falling on the patient's face.

For patients who need dental filling, resin filling is required after the cavity preparation is completed. The stomatologist needs to rely on a light curing machine to complete this work, but the light curing machine emits dazzling blue light, which is harmful to the doctor's The eyes are harmful. At this time, the dentist can control the motor 9 to switch to anti-blue light lenses that can isolate blue light, so as to avoid being irradiated by blue light. For patients who need physical therapy or surgical treatment with a laser knife, the dentist needs to use a laser. The laser therapy device will produce red light that has strong radiation damage to the eyes during the working process. In this case, the dentist can control the motor 9 to switch the anti-red light lens that can isolate the laser to solve the problem of laser light. Radiation eye problems.

In addition, in order to solve the problem that the light curing machine or the handle of the laser therapeutic apparatus blocks the sight of the dentist, the dentist can observe the internal situation of the patient's oral cavity by adjusting the angle of the reflective lens 5 without changing the posture of his head.

Finally, in the post-processing process, the dentist will polish the surface of the teeth and clean the residues in the patient's mouth at the same time. This process will also generate some mist, but it will eventually flow to the outside through the groove 7 .

When the dentist completes the entire treatment process, the headband 8 needs to be loosened to take off the protective mask, the protective plate 3, the groove 7 and the suction tube are simply cleaned, and then stored for next use.

It can be seen from the above working process that the composite stomatologist protective mask of the present invention can prevent the inner surface of the protective plate from fogging through the action of the cooling fan; It is beneficial to prevent the splashed liquid and tooth debris from adhering to the mask, causing the mask to fog and block the sight, which improves the convenience and safety of the user when working; the slideway 2 and the double-lens structure can be used without removing the lens. In this case, the lenses can be freely switched according to the needs of use. Compared with the traditional working mode that requires additional wearing of protective glasses, the present invention significantly improves the work efficiency of doctors; the structure of the reflective lens 5 on the mask protective plate 3 can When there is a block in front of the dentist, the stomatologist can operate through the reflective lens 5 without changing the posture of the head, so as to avoid fatigue when working for a long time at a special sight angle; The use needs to be adjusted freely, which improves the comfort of the stomatologist when working.
