[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figure 1 , Figure 3 and Figure 6This utility model provides an embodiment of a defogging type bomb disposal mask, including a mask body 1, which serves to protect the user's face. A defogging heating film 2 is provided on the front side of the mask body 1. The defogging heating film 2 is curved and can fit snugly against the mask body 1, with sealed edges to ensure its sealing and weather resistance. A protective layer is provided on the front side of the defogging heating film 2, and a heating layer is provided behind the protective layer. The heating layer is electrically connected to a connecting wire 56. An insulating layer is provided behind the heating layer. The protective layer on the front side is made of polycarbonate, which has high strength and elasticity, high impact strength, high transparency, good heat resistance, good dimensional stability, good fatigue resistance, good weather resistance, and excellent electrical properties, effectively preventing defogging. The heating film 2 is damaged by scratches, impacts, etc. The heating layer is a transparent conductive film with nano-silver wires, which has high transparency and good conductivity. It is flexible and can generate heat quickly and evenly when current passes through it. It heats and removes any fog that may appear on the mask body 1 to prevent obstruction of vision. The insulating layer is made of polyimide, which has good insulation performance and high temperature resistance. It can maintain stable insulation characteristics in high temperature environments. It also has high transparency and will not affect the observation effect of the defogging heating film 2. It also has good flexibility and mechanical strength, which can effectively protect the heating layer and prevent leakage. A mounting shell 3 is provided on the right side of the mask body 1 to provide installation space for the control chip 9. A connection port is provided on the front side of the mounting shell 3 for connecting an external power supply.
[0034] Reference Figure 2 - Figure 4 A control chip 9 is installed on the inner wall of the mounting shell 3 to control the operation of the heating layer. It receives and processes signals from the temperature sensor 4 (model STM32H7), which is electrically connected to the temperature sensor 4. A temperature sensor 4 is inserted into the lower side of the mounting shell 3 to detect the temperature around the mask body 1 and transmits the temperature signal to the control chip 9. The control chip 9 then adjusts the operating state of the heating layer according to the temperature. This technology is existing and will not be described in detail. A defogging assembly is installed on the inner wall of the mask body 1. The defogging assembly includes a connecting wire 56, which transmits signals from the control chip 9 to the heating layer on the defogging heating film 2 to control the operation of the heating layer. 6 is set on the inner wall of the mask body 1. The connecting wire 56 is electrically connected to the control chip 9 and the heating layer on the defogging heating film 2. The front side of the mask body 1 is fixedly connected to the slide rail 51. The slide rail 51 is provided in two sets, one upper and one lower, to provide a sliding track for the slider 52, so that the cleaning plate 53 can move left and right on the outside of the mask body 1. The slider 52 is slidably connected to the inner wall of the slide rail 51. By sliding the slider 52, the cleaning plate 53 and the cleaning plate 55 are moved to clean the defogging heating film 2. The top of the slider 52 is fixedly connected to the cleaning plate 53 for cleaning the front side of the mask body 1 and the defogging heating film 2.
[0035] Reference Figure 2 , Figure 3 and Figure 5 A slide rail 54 is provided on the rear side of the mask body 1, providing a sliding track for the other two sets of sliders 52, allowing the cleaning plate 55 to move left and right on the rear side of the mask body 1. Multiple sets of sliders 52 are provided, with the other two sets slidably connected to the inner wall of the slide rail 54. The cleaning plate 55 is fixedly connected to the opposite side of the other two sets of sliders 52, working in conjunction with the cleaning plate 53 to clean the rear side of the mask body 1 and the defogging heating film 2. The rear side of the cleaning plate 53 and the front side of the cleaning plate 55 are attached to the outer side of the mask body 1. The cleaning plate 53 and the cleaning plate 55... Magnets 6 are provided on the inner wall to attract and fix the cleaning plate 1 53 and the cleaning plate 2 55 together. When the cleaning plate 1 53 is pulled, the cleaning plate 2 55 can be moved, thereby quickly cleaning the water mist on the front and back sides of the mask body 1 and the defogging heating film 2. Sponge pads are provided on the back side of the cleaning plate 1 53 and the front side of the cleaning plate 2 55 to absorb water mist. At the same time, they play a buffering and protective role when cleaning the defogging heating film 2 to prevent scratching the defogging heating film 2. A heat dissipation hole 7 is provided through the front side of the mask body 1 to help maintain air circulation inside the mask body 1.
[0036] Reference Figure 3 and Figure 4 The inner wall of the mounting shell 3 is provided with a limiting component, which includes a limiting plate 81. Under the action of a compression spring 82, it can be inserted into the inner wall of the limiting groove 83 on the outside of the temperature sensor 4 to fix the temperature sensor 4 and prevent the temperature sensor 4 from accidentally falling off or loosening during use. The limiting plate 81 is slidably connected to the inner wall of the mounting shell 3. The limiting plate 81 is designed in an L shape to facilitate the user to pull it, thereby quickly releasing the limiting of the temperature sensor 4. The front side of the limiting plate 81 is elastically connected to the mounting shell 3 through the compression spring 82. The elastic force keeps the limiting plate 81 in the state of being inserted into the limiting groove 83 to fix the temperature sensor 4. The outer side of the temperature sensor 4 has a limiting groove 83, which cooperates with the limiting plate 81 to fix the temperature sensor 4. The limiting plate 81 is inserted into the inner wall of the limiting groove 83.
[0037] Working principle: When the temperature sensor 4 is inserted into the lower side of the mounting shell 3, the limiting groove 83 on the outside of the temperature sensor 4 corresponds to the position of the limiting plate 81. Under the action of the compression spring 82, the limiting plate 81 is inserted into the inner wall of the limiting groove 83 to fix the temperature sensor 4 and prevent it from accidentally falling off or loosening during use.
[0038] At this time, the temperature sensor 4 detects the temperature around the mask body 1 in real time and transmits the temperature signal to the control chip 9. The control chip 9 transmits power to the heating layer on the defogging heating film 2 through the connecting wire 56. The heating layer is a transparent conductive film with nano-silver wires. After being powered on, it quickly and evenly generates heat. The heat is transferred to the surface of the defogging heating film 2, causing any fog to evaporate, thereby keeping the defogging heating film 2 clear and preventing obstruction of vision.
[0039] When there is a lot of water mist on the defogging heating film 2, the user pulls the cleaning plate 1 53. Since the inner walls of the cleaning plate 1 53 and the cleaning plate 2 55 are equipped with magnets 6, when the cleaning plate 1 53 is pulled, the cleaning plate 2 55 will also slide in the slide rail 2 54 on the rear side of the mask body 1 through the other two sets of sliders 52, so that the cleaning plate 1 53 and the cleaning plate 2 55 move at the same time to clean the front and back sides of the defogging heating film 2.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
