[0021] The present utility model will be further described in detail below in conjunction with the drawings and specific implementation manners. The embodiments of the present utility model are given for the purpose of illustration and description, and are not exhaustive or limit the present utility model to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present utility model, and enable those of ordinary skill in the art to understand the present utility model and thus design various embodiments with various modifications suitable for specific purposes.

[0022] Please refer to Figures 1 to 4, in this embodiment, a dust-proof device for a nasal oxygen tube is provided, including a base 1. A winding mechanism 3 is fixedly connected to the base 1. A dust-proof cover 2 is sleeved outside the winding mechanism 3 on the base 1, and the lower end of the dust-proof cover 2 is inserted into the interior of the base 1.

[0023] The winding mechanism 3 includes a winding box 33. A plurality of movable plates 31 are slidably connected to both sides of the winding box 33. A lifting rod 35 is vertically slidably connected inside the winding box 33. The upper end of the lifting rod 35 passes through the winding box 33 and is fixedly connected to a placement plate 32.

[0024] During use, the nasal oxygen tube is wound around the outside of the winding mechanism 3, and then the dust-proof cover 2 is put on the outside of the base 1, and the nasal oxygen tube is enclosed between the dust-proof cover 2 and the base 1 to dust-proof the nasal oxygen tube.

[0025] During the winding process, the nasal oxygen tube is separated by a plurality of movable plates 31 to prevent it from being scattered inside. The nasal suction head of the nasal oxygen tube can be separately clamped and placed by the placement plate 32, reducing the large space occupied by the nasal suction head during the winding process.

[0026] In a further embodiment, the placement plate 32 is provided with a card slot that matches the nasal suction head of the nasal oxygen tube assembly. The nasal suction head can be clamped through the card slot.

[0027] In a further embodiment, refer to Figure 3 , symmetrically arranged connecting plates one 34 are provided on both sides inside the winding box 33. One end of the movable plate 31 is fixedly connected to the connecting plate one 34, and the other end of the movable plate 31 passes through the winding box 33. A connecting plate two 38 is arranged outside the lifting rod 35. A connecting rod 39 is connected between one end of the connecting plate two 38 and the connecting plate one 34. A connecting head 36 is fixedly connected to the lower end of the lifting rod 35. A clamping block 37 is arranged at the lower end inside the winding box 33. When the connecting plate two 38 descends, the upper end of the connecting rod 39 descends, and the lower end of the connecting rod 39 spreads out to both sides to push the connecting plate one 34 to move outward. The connecting plate one 34 thus pushes the movable plate 31 to move outward. When the lifting rod 35 descends, the connecting head 36 descends below the clamping block 37, and the clamping block 37 clamps the connecting head 36 to keep the lifting rod 35 in the lower position.

[0028] In a further embodiment, refer to Figure 4, the two sides at the lower end of the connector 36 are arc-shaped, the sides of the upper ends of the clamping blocks 37 close to each other are arc-shaped, the clamping blocks 37 are slidably connected to the base 1, a spring is provided between the clamping blocks 37 and the base 1, the minimum distance between the clamping blocks 37 is greater than the width of the connector 36, and the internal width of the winding box 33 is greater than the length of the connector 36. Through the arc-shaped contact between the arc-shaped lower end of the connector 36 and the clamping blocks 37, the clamping blocks 37 can be pushed to both sides during the process of the lifting rod 35 descending and the connector 36 descending. When the connector 36 descends below the clamping blocks 37, the clamping blocks 37 move above the connector 36 under the action of the spring to clamp the connector 36, so as to keep the movable plate 31 on the outside, and thus winding can be carried out. When removing the nasal suction tube, by rotating the lifting rod 35, the connector 36 rotates and loses the block, so it can rise, and the lifting rod 35 rises accordingly, so that the movable plate 31 can be retracted.

[0029] In a further embodiment, refer to Figures 3 to 4 , a spring is provided between the second connecting plate 38 and the upper part inside the winding box 33. A connecting block 351 is fixedly connected to the outside of the lifting rod 35, and the connecting block 351 is located above the second connecting plate 38. The spring makes the second connecting plate 38 always keep upward, so as to keep the first connecting plate 34 inward, so that the movable plate 31 keeps the contracted state. Without external restriction, the movable plate 31 keeps inside the winding box 33, so that there is no obstruction outside the winding box 33, and thus the nasal suction tube outside the winding box 33 can be pushed out.

[0030] In a further embodiment, refer to Figure 3 , the inclined ends of the connecting rods 39 are inclined upward, and the two ends of the connecting rods 39 are respectively rotatably connected to the first connecting plate 34 and the second connecting plate 38. By the inclined upward of the connecting rods 39, it is ensured that the lower ends of the connecting rods 39 are separated to both sides during the process of the lifting rod 35 descending. Thus, when the user presses the nasal suction head on the placing plate 32, the lifting rod 35 also descends by the way. During the process of the lifting rod 35 descending, the movable plate 31 is also pushed out at the same time, so as to achieve the effect of one-step completion, thereby improving the convenience during use.

[0031] In a further embodiment, a groove matching the lower end of the dust-proof cover 2 is provided inside the base 1. The base 1 is made of elastic material, and the width of the groove is smaller than the wall thickness of the dust-proof cover 2. The elastic material enables the lower end of the dust-proof cover 2 to be inserted into the groove, and at the same time, the dust-proof cover 2 is clamped through the deformation of the elastic material, so as to prevent the dust-proof cover 2 from falling off easily.

[0032] Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art and related fields based on the embodiments in the present utility model without creative efforts shall fall within the protection scope of the present utility model. Structures, devices, and operation methods not specifically described and explained in the present utility model shall be implemented by conventional means in the art without special explanation and limitation.
