Detailed implementation mode

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0029] An embodiment of the present application discloses a blowing mirror. Refer to Figures 1 to 5 , the blowing mirror includes a hand-held rod 1 and a lens 2. Specifically, the hand-held rod 1 is in a strip shape for the user to hold. An accommodation chamber 11 is provided inside the hand-held rod 1 for arranging components. The extending direction of the accommodation chamber 11 is along the length direction of the hand-held rod 1. A PCBA board 17, a battery 18 and a fan assembly 3 are arranged in the accommodation chamber 11. The PCBA board 17 is electrically connected to the battery 18 and the fan assembly 3 respectively. A plurality of buttons extending out of the hand-held rod 1 are arranged on the PCBA board 17 to realize different functions. The fan assembly 3 is arranged at one side edge inside the accommodation chamber 11. The fan assembly 3 is composed of a fan and a motor. The fan assembly 3 is a prior art and will not be elaborated too much in this application. In this embodiment, the PCBA board 17 and the battery 18 assembly are both arranged on the upper side of the accommodation chamber 11 perpendicular to its own length direction, and the lower side is used for the fan assembly 3 to blow air. An air outlet 14 is arranged on the side of the hand-held rod 1 away from the fan assembly 3. The air outlet 14 is communicated with the accommodation chamber 11, so that the fan assembly 3 moves the air from the lower side of the accommodation chamber 11 to the air outlet 14 and blows it out. The air outlet 14 can be arranged on the end face of the hand-held rod 1 or on the side wall of the hand-held rod 1 to adapt to different inspection situations; the lens 2 is connected to the side of the hand-held rod 1 away from the fan, and the lens 2 is connected to the hand-held rod 1 in a predetermined posture. The air outlet 14 is arranged corresponding to the lens 2. When the fan assembly 3 blows air out of the air outlet 14, the air can be blown onto the lens 2. Therefore, when using the blowing mirror for oral or other inspections, if fog appears on the lens 2, press the corresponding button on the PCBA board 17 to start the fan assembly 3. The fan assembly 3 accelerates the air to blow out of the air outlet 14 to disperse the fog on the lens 2, so that the mirror remains clear, so that the lens 2 can be cleaned without taking out the mirror, which helps to improve the convenience of using the mirror.

[0030] Refer to Figure 2 and Figure 3The hand-held rod 1 includes a base rod 12 and a replacement rod 13. Both the base rod 12 and the replacement rod 13 are hollow. The base rod 12 and the replacement rod 13 are opened on one side close to each other. The internal spaces of the base rod 12 and the replacement rod 13 are combined to form a complete accommodating chamber 11. The PCBA board 17, the battery 18 and the fan assembly 3 are arranged inside the base rod 12, and the air outlet 14 is arranged on the replacement rod 13. The side of the base rod 12 close to the replacement rod 13 is arranged in a stepped shape, and the part of the stepped shape close to the replacement rod 13 has a smaller cross-sectional area when viewed from a direction parallel to its own length. An annular groove 121 is arranged on this part. There are two annular grooves 121. The axis of the annular groove 121 is parallel to the length direction of the base rod 12. Rubber rings 122 are respectively embedded in the two annular grooves 121. The rubber ring 122 has The rubber ring 122 is made of elastic material, and the rubber ring 122 will extend from the notch of the annular groove 121. The side of the replacement rod 13 close to the base rod 12 is sleeved on the stepped part of the base rod 12, and the inner wall of the replacement rod 13 will abut against the part of the rubber ring 122 extending out of the annular groove 121. When the replacement rod 13 is inserted into the stepped part of the base rod 12, the rubber ring 122 will form a connection with the inner wall of the replacement rod 13 with a predetermined strength to achieve a detachable connection between the replacement rod 13 and the base rod 12. When the replacement rod 13 is replaced according to actual usage, the original replacement rod 13 is first pulled off the base rod 12, and then the new replacement rod 13 is aligned with the base rod 12 and directly inserted. Therefore, different lenses 2 can be selected for replacement according to different situations, so that the air-blown reflector is suitable for more situations.

[0031] Reference Figure 2 and Figure 3 At the same time, in order to improve the installation stability of the replacement rod 13, a notch 15 is provided at the opening of the replacement rod 13, and a clamping block 123 is provided on the stepped side wall of the base rod 12. The clamping block 123 is adapted to the shape of the notch 15. When the replacement rod 13 is installed on the base rod 12, the clamping block 123 will be stuck in the notch 15, and the replacement rod 13 is restricted by the side wall of the notch 15 to prevent the replacement rod 13 from rotating along the axis of the base rod 12 during use of the blowing reflector, thereby helping to improve the installation stability of the replacement rod 13.

[0032] Reference Figures 2 to 4 In order to blow away the fog on the lens 2 as much as possible, the cross-sectional area of ​​the side of the replacement rod 13 close to the lens 2 is smaller than the cross-sectional area of ​​the side close to the base rod 12, and the cross-sectional area of ​​the air outlet 14 is also smaller than the cross-sectional area at the opening of the replacement rod 13. Therefore, when the air passes through the replacement rod 13 and comes out of the air outlet 14, the flow rate of the air will be further accelerated, so that the force of the air acting on the lens 2 will be increased, thereby better blowing away the fog on the lens 2.

[0033] Reference Figures 2 to 4, in this embodiment, the lens 2 is connected to the replacement rod 13 at a certain inclination angle. For example, the angle between the lens 2 and the replacement rod 13 is 40° to 45°. And the air outlet hole 14 is provided on the side wall of the replacement rod 13. At the same time, a light outlet hole 16 is provided on the side wall of the replacement rod 13. The light outlet hole 16 is arranged corresponding to the lens 2. An LED lamp 4 is arranged inside the base rod 12. The LED lamp 4 is electrically connected to the PCBA board 17. There are two LED lamps 4, and the two LED lamps 4 are arranged side by side at the upper side of the opening of the base rod 12. The two LED lamps 4 can emit white high-brightness light and warm-color light and can be switched between these two kinds of lights. The light emitted by the LED lamp 4 can be irradiated onto the lens 2 from the light outlet hole 16. At this time, when the blowing mirror is used in a relatively dark environment, the LED lamp 4 is turned on through the PCBA board 17, and the light is reflected by the lens 2 to facilitate the user's observation, so that the blowing mirror is suitable for use in a relatively dark environment.

[0034] Refer to Figures 3 to 5 , at the same time, in order to ensure that the air outlet hole 14 does not affect the air velocity at the air outlet hole 14 when the blower assembly 3 is working, the air outlet hole 14 is arranged close to the lens 2, that is, the distance between the air outlet hole 14 and the lens 2 is less than the distance between the light outlet hole 16 and the lens 2, so that the air is closer to the lens 2 when blowing out of the accommodation chamber 11, and the fog can be more effectively dispersed. At the same time, a partition plate 5 is arranged inside the replacement rod 13. The partition plate 5 divides the chamber inside the replacement rod 13 into upper and lower chambers. The upper chamber 131 is communicated with the light outlet hole 16, and the lower chamber 132 is communicated with the air outlet hole 14. And when the replacement rod 13 is installed on the base rod 12, the partition plate 5 is located at the opening of the base rod 12, and the lower side of the opening of the base rod 12 corresponds to the lower chamber 132 of the replacement rod 13, so that the air can be directly blown into the lower chamber 132 from the base rod 12 and then discharged from the air outlet hole 14, which can reduce the dispersion of the air and further ensure the fog-dispersing effect.

[0035] Refer to Figures 3 to 5 , in this embodiment, in order to increase the functionality of the blowing mirror, a plurality of display lamps 19 are arranged on the PCBA board 17. The display lamps 19 are arranged side by side at intervals. At the same time, a plurality of display holes 124 corresponding to the display lamps 19 are arranged on the base rod 12 to facilitate the user to check the battery 18 power. In this embodiment, there are three display lamps 19. The three display lamps 19 respectively display red, blue and green lights in sequence. When the green light is on, it represents 100% power. When the blue light is on, it represents 50% power. When the red light is on, it represents 20% power. And the three display lamps 19 can also be used for gear display, that is, different gears represent different output voltages, which is convenient for the user to use.

[0036] The implementation principle of a blowing mirror in an embodiment of the present application is as follows: During the process of using the blowing mirror for oral or other part examinations, if the lens 2 senses a change in heat and causes air to generate fog on the lens 2, at this time, press the corresponding button on the PCBA board 17 to start the fan assembly 3. The fan assembly 3 drives the air to directly blow towards the lens 2 from the air outlet 14 to disperse the fog on the lens 2, keeping the mirror clear, so that the lens 2 can be cleaned without taking out the mirror, which helps to improve the convenience of using the mirror.

[0037] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
