[0033] Embodiment 2:

[0034] On the basis of Example 1, in order to make the cotton towel 27 in a stretched state and close to the wearer's nose surface, the limiting guide mechanism includes two limiting rollers 7, and a rubber layer is provided on the outer side of the limiting roller 7. The elasticity of the rubber layer enables the cotton towel 27 to be clamped between the two limiting rollers 7. The upper ends of the two limiting rollers 7 are movably connected to the lower end of the connecting plate 21, and the lower ends are movably connected to the upper end of the T-shaped slider 30. The T-shaped slider 30 is slidably connected to the T-shaped slot 28. The upper ends of the left bottom plate 6 and the right bottom plate 2 are both provided with T-shaped slots 28. Two supporting springs 37 are fixedly connected in the T-shaped slot 28. The other ends of the supporting springs 37 are fixedly connected to the T-shaped slider 30. There is a push switch 36. When the nose pad 4 contacts the wearer's nose, the cotton towel 27 will be squeezed and pulled. Since the limiting roller 7 is fixed by a limit position, the limiting roller 7 will follow and move during the squeezing and pulling of the cotton towel 27. The movement of the limiting roller 7 will compress the supporting spring 37 and press the push switch 36. When the wearing is completed, under the elastic force of the supporting spring 37, the T-shaped slider 30 returns to the initial position, and the upper end of the liquid-conducting cotton strip 40 contacts a limiting roller 7. The wind oil is transferred to the surface of the cotton towel 27 through the rotation of the limiting roller 7. When the limiting roller 7 moves and bounces back to the initial position, the liquid-conducting cotton strip 40 will contact the surface of the limiting roller 7 again.

[0035] A plurality of limiting holes 34 are provided at the lower end of the limiting roller 7, and a limiting cavity 31 is provided at the upper end of the T-shaped slider 30. A T-shaped limiting rod 33 is slidably connected in the limiting cavity 31. The upper end of the T-shaped limiting rod 33 is clamped in the limiting hole 34. A return spring 32 is fixedly connected in the limiting cavity 31. The other end of the return spring 32 is fixedly connected to the T-shaped limiting rod 33. An electromagnet 35 is provided on the inner side of the return spring 32. The electromagnet 35 can be used with a suitable size and model in actual use. The lower end of the electromagnet 35 is fixedly connected to the limiting cavity 31. After the micro motor 25 is punched, the two electromagnets 35 will be started. After the electromagnet 35 is started, the T-shaped limiting rod 33 is attracted. At this time, the clamping end of the T-shaped limiting rod 33 is separated from the limiting hole 34, and the return spring 32 is compressed. At this time, the limiting roller 7 is in a rotatable state.

[0036] The winding mechanism includes a winding roller 14, the outer side of the winding roller 14 is movably connected with a clamping plate 8, the lower end of the winding roller 14 is provided with a square groove 13, a square rod 29 is inserted in the square groove 13, the square rod 29 is fixedly connected to the output end of the micro motor 25, and the micro motor 25 is fixedly installed in the lower end of the left bottom plate 6. When the cotton towel 27 located on the outer side of the roller 22 is used, the winding roller 14 with the used cotton towel 27 can be removed by removing the left bottom plate 6. The clamping plate 8 is fixedly connected to two sides near the winding roller 14. A T-shaped connecting rod 16 is slidably connected in a guide cavity 17, and the guide cavity 17 is opened in the winding roller 14. A connecting spring 15 is sleeved on the outer side of the T-shaped connecting rod 16. One end of the connecting spring 15 is fixedly connected to the guide cavity 17, and the other end is fixedly connected to the T-shaped connecting rod 16. The splint 8 is pulled outward to pass one end of the cotton towel 27 through the splint 8 and the winding roller 14, and the pull on the splint 8 is released. At this time, under the elastic force of the connecting spring 15, the cotton towel 27 is clamped between the splint 8 and the winding roller 14.

[0037] Working principle: when in use, the roller 22 with the rolled cotton towel 27 is sleeved on the outer side of the positioning rod 26. After the sleeve is completed, one end of the cotton towel 27 is passed through the two limiting rollers 7 on the right and the two limiting rollers 7 on the left. After the insertion is completed, the clamping plate 8 is pulled outward to pass one end of the cotton towel 27 through the clamping plate 8 and the winding roller 14, and the pulling on the clamping plate 8 is released. At this time, under the elastic force of the connecting spring 15, the cotton towel 27 is clamped between the clamping plate 8 and the winding roller 14, and the left bottom plate 6 and the right bottom plate 2 are respectively installed in the corresponding connecting cavity 3. During the installation process, ensure that the cotton towel 27 enters the make way groove 20 and the positioning groove 24. After the installation is completed, turn on the micro motor 25 to drive the square rod 29 connected to its output end to start rotating;

[0038] After the micro motor 25 is punched, the two electromagnets 35 are started. After the electromagnets 35 are started, the T-shaped limit rod 33 is attracted. At this time, the clamping end of the T-shaped limit rod 33 is disengaged from the limit hole 34, and the reset spring 32 is compressed. At this time, the limit roller 7 is in a rotatable state. Since the square rod 29 is inserted into the square groove 13, the winding roller 14 is driven to start rotating when the square rod 29 rotates. At this time, the cotton towel 27 will be wound and straightened. When the straightening is completed, the micro motor 25 is turned off. At this time, under the elastic force of the reset spring 32, the T-shaped limit rod 33 is clamped into the limit hole 34 again, so that the limit roller 7 cannot continue to rotate.

[0039] The VR host 1 can be worn on the user's face through the elastic strap 18. Since the nose pad 4 is in a movable state, when the VR host 1 is worn, the nose pad 4 will automatically tilt at an angle to contact the wearer's nose. In the process of the nose pad 4 contacting the wearer's nose, the cotton towel 27 will be squeezed and pulled. Since the limiting roller 7 is limited and fixed, the limiting roller 7 will move along with the cotton towel 27 in the process of being squeezed and pulled. The movement of the limiting roller 7 will compress the support spring 37 and press the push switch 36. At this time, the cooling fan 11 will start, and the cooling fan 11 will guide the air into the guide cavity 9, and finally slowly discharge it into the external environment through the elastic cotton strip 19, so as to reduce the temperature of the contact point between the elastic cotton strip 19 and the user's face in a hot environment;

[0040] When the user is changed, the micro motor 25 can be turned on again to reel in the cotton towel 27 with impurities such as sweat adhered to it, and a new cotton towel 27 can be moved to the position of the nose pad 4.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
