[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1, as Figure 1-Figure 4As shown, the utility model provides a device for preventing respiratory tract infection, including: a hood 1, the outer surfaces of both sides of the hood 1 are rotatably connected to a rotating seat 2, the end surface of the rotating seat 2 is fixedly connected to a support arm 3, the lower end surface of the support arm 3 is provided with a notch, the bottom of the notch is fixedly connected to a spring 4, the end surface of the spring 4 is fixedly connected to an insert block 5, and an elastic band 6 is fixedly connected between the two insert blocks 5; a breathing component 8, the breathing component 8 is fixedly connected to the outer surface of the support arm 3, the breathing component 8 includes two gaskets 801, two connecting plates 803 and two support rods 806, a mask 807 is fixedly connected between the two support rods 806, and the outer surface of the mask 807 is fixedly connected to a breathing Straw 808, the outer surface of the gasket 801 is fixedly connected to the first screw 802, the outer surface of the first screw 802 is threadedly connected to the first hand-tightening nut 805, the outer surface of the connecting plate 803 is provided with a slide groove 804, the connecting plate 803 is located between the gasket 801 and the first hand-tightening nut 805, the end face of the support rod 806 is fixedly connected to a stopper 809, the outer surface of the stopper 809 is fixedly connected to the second screw 810, the outer surface of the second screw 810 is slidably connected to the inner surface of the slide groove 804, the outer surface of the second screw 810 is threadedly connected to the second hand-tightening nut 811, and the connecting plate 803 is located between the stopper 809 and the second hand-tightening nut 811.

[0023] The effect achieved by the entire embodiment 1 is that when the respiratory tract infection prevention device is used on a child, the hood 1 is covered from the top of the child's head to complete the wearing, and then the elastic band 6 is put on the child's chin. The spring 4 is set to provide support for the plug block 5, so that the plug block 5 can slide freely up and down in the groove. According to the size of the child's head, the use position of the plug block 5 can be freely adjusted. After the plug block 5 is pulled down to the child's chin, the elastic band 6 is put on the chin. At this time, the rebound force of the spring 4 is used to provide support for the elastic band 6, so that the elastic band 6 applies pressure upward, so that the device is firmly put on the child's head. The device is supported by the child's head and chin, and its supporting position is relatively stable and not easy to fall off. Compared with the traditional way of putting it on the ears, it has the advantage of strong stability. After the device is worn on the child's head, the use position of the mask 807 is adjusted, and the first hand is loosened. After tightening the nut 805, the connecting plate 803 can rotate freely. After the connecting plate 803 drives the mask 807 to adjust to a suitable inclination angle that fits the child's face, the first hand-tightening nut 805 is tightened to tighten the position of the connecting plate 803, and then the distance between the mask 807 and the child's face is adjusted. After loosening the second hand-tightening nut 811, the support rod 806 can drive the second screw rod 810 to slide on the inner side of the slide groove 804. After the mask 807 is moved to a position that fits the child's face through the movement of the support rod 806, the second hand-tightening nut 811 is tightened to fix the position of the support rod 806, and the child is treated with atomization by the coordinated use of the mask 807 and the breathing tube 808. At this time, the use position of the mask 807 is supported by the support arm 3 as a fixed position, and the relatively stable fixed position of the head cover 1 and the elastic band 6 can make the mask 807 not easy to fall off during use, which has a better effect on children.

[0024] Embodiment 2, as Figure 1-Figure 4 As shown, the outer surface of the insert block 5 is slidably connected to the inner surface of the slot, and the outer surface of the elastic band 6 is adhered with sterile gauze 7.

[0025] The effect achieved by the entire embodiment 2 is that when the hood 1 and the elastic band 6 are used together to fix the child's head, the sterile gauze 7 is in contact with the child's chin skin. The use of the sterile gauze 7 can avoid the problem of children's skin allergies compared to the use of traditional rubber straps, thereby improving the comfort of children when using the device.

[0026] Working principle: When using the respiratory infection prevention device for children, the hood 1 is covered from the top of the child's head to complete the wearing, and then the elastic band 6 is put on the child's chin. The spring 4 is set to provide support for the plug block 5, so that the plug block 5 can slide up and down freely in the slot. According to the size of the child's head, the use position of the plug block 5 can be freely adjusted. After the plug block 5 is pulled down to the child's chin, the elastic band 6 is put on the chin. At this time, the rebound force of the spring 4 is used to provide support for the elastic band 6, so that the elastic band 6 is applied upward. The device is supported by the child's head and chin, and its support position is relatively stable and not easy to fall off. Compared with the traditional way of putting it on the ears, it has the advantage of strong stability. After the device is worn on the child's head, the use position of the mask 807 is adjusted. After loosening the first hand-tightening nut 805, the connecting plate 803 can rotate freely. After the connecting plate 803 drives the mask 807 to adjust to a suitable inclination angle that fits the child's face, tighten it. After the first hand-tightening nut 805 is tightened to fix the position of the connecting plate 803, the distance between the mask 807 and the child's face is adjusted. After the second hand-tightening nut 811 is loosened, the support rod 806 can drive the second screw rod 810 to slide on the inner side of the slide groove 804. After the mask 807 is moved to a position fitting the child's face by the movement of the support rod 806, the second hand-tightening nut 811 is tightened to fix the position of the support rod 806. The mask 807 and the breathing tube 808 are used in conjunction to perform atomization treatment on the child. The use position is supported by the support arm 3 as a fixed position, and the head cover 1 and the elastic band 6 are used to fix the position more stably, so that the mask 807 is not easy to fall off during use, which has a better effect on children. When the head cover 1 and the elastic band 6 are used to fix the head of the child, the sterile gauze 7 is in contact with the skin of the child's chin. The use of the sterile gauze 7 can avoid the problem of children's skin allergies compared to the use of traditional rubber straps, thereby improving the comfort of children when using the device.

[0027] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
