Abstract
Description
Technical Field
[0001] This utility model belongs to the field of earplug technology, and more specifically, it relates to a cooling and noise-reducing earplug. Background Technology
[0002] Power plant workers live and work in an environment combining high temperatures and noise year-round, and are frequently exposed to high noise levels. On-site tests showed that the noise level in the power plant's dormitory reached 55 decibels, the noise level in the duty room reached 64 decibels, the noise level in the machine room reached 90 decibels, and the temperature in the machine room was 35°C. Working and living in such an environment year-round, without effective hearing protection, will inevitably lead to noise-induced hearing loss, reducing work efficiency and causing irreversible damage to the physical and mental health of power plant workers. Existing earplugs cannot effectively block noise and cannot adequately cool the ears.
[0003] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide a cooling and noise-canceling earplug, in order to achieve a more practical purpose. Utility Model Content

[0010] Furthermore, a second limiting tooth is installed in the middle of the fixing rod, and a second fixing groove is provided on the limiting plate, with the second limiting tooth engaging with the interior of the second fixing groove.
[0011] Furthermore, there are two connectors and earplugs, and the two connectors are connected by an adjustment rope, with both ends of the adjustment rope wound around the central post.
[0012] Furthermore, the outer side of the adjusting rope is wrapped with a cooling layer.
[0013] Furthermore, the silicone includes polydimethylsiloxane, wax pellets, polyvinyl chloride, and silicone putty.
[0014] Furthermore, the physical cooling layer comprises polyethylene propylene, water, glycerol, hydroxypropyl methylcellulose, patchouli and artemisia extract, and hydrophilic polymer materials.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] This utility model of earplugs can reduce noise and prevent hearing loss without affecting normal work. From the perspective of protecting the ears and preventing hearing loss, it uses highly malleable and comfortable materials, which can improve the autonomy of power station staff in wearing earplugs and achieve the purpose of reducing noise and cooling.

[0028] Example:
[0029] As attached Figure 1 To be continued Figure 5 As shown:
[0030] This utility model provides a cooling and noise-canceling earplug, including a connector 1 and an earplug 2. The inner core of the earplug 2 is made of malleable silicone 4, and a polyethylene foam 6 is disposed on the outside of the silicone 4. A physical cooling layer 5 is disposed on the outside of the polyethylene foam 6, and the outside of the physical cooling layer 5 is wrapped with polyethylene foam 6. A sterile cotton cloth 7 is disposed on the outside of the polyethylene foam 6. The inner core of the earplug 2 is made of malleable silicone 4. The malleable silicone 4 is made of materials including but not limited to polydimethylsiloxane, wax pellets, polyvinyl chloride, silicone putty, etc. The malleable silicone 4 is waterproof and highly malleable. When rubbed by hand, it will slowly expand and gradually return to its original shape. The physical cooling layer 5 is composed of polyethylene propylene, water, glycerin, hydroxypropyl methylcellulose, patchouli and artemisia extract, hydrophilic polymer materials, etc. It is made with moderate thickness and softness, which can provide both comfortable wear and cooling effect. It can reduce the damage to hearing caused by the combined effects of high temperature and noise. The material of the cooling layer wrapped around the earplug 2 is also made of polyethylene foam, which has water absorption and moisture absorption properties, helping to keep the ear canal dry during the wearing of the earplug 2. The outer surface of the earplug 2 is made of a layer of sterile cotton cloth 7, which can absorb sweat from the ear canal, avoid moisture causing external auditory canal inflammation, and improve wearing comfort.
[0031] The connector 1 has a central column 8 on one side, and a rotating cylinder 10 is sleeved on the outside of the central column 8. The central column 8 is movably connected to a rotating component 9 through the rotating cylinder 10. A connecting column 11 is installed on one side of the rotating component 9. A limiting plate 12 is installed at one end of the connecting column 11. A fixing rod 14 is inserted into the inner side of the limiting plate 12. One end of the fixing rod 14 is connected to the inner side of the central column 8. When the fixing rod 14 is pulled outward, the first fixing groove 15 and the first limiting tooth 16 at one end are separated. At this time, the second fixing groove 13 and the second limiting tooth 17 are separated. Then, the rotating component 9 is rotated to drive the rotating cylinder 10 to rotate. When the rotating cylinder 10 rotates, it can wind up the adjusting rope 3.
[0032] The central column 8 has a first fixing groove 15 on its inner side, and a first limiting tooth 16 is provided at one end of the fixing rod 14. The first fixing groove 15 and the first limiting tooth 16 are engaged. A second limiting tooth 17 is installed in the middle of the fixing rod 14. A second fixing groove 13 is provided on the limiting plate 12. The second limiting tooth 17 is engaged into the interior of the second fixing groove 13. The first limiting tooth 16 at the lower end of the fixing column 14 re-enters the interior of the first fixing groove 15, and the second limiting tooth 17 enters the interior of the second fixing groove 13. At this time, the fixing rod 14 is restricted by the first fixing groove 15 and the first limiting tooth 16 and cannot rotate.
[0033] The device comprises two connectors 1 and two earplugs 2, which are connected by an adjusting rope 3. The two ends of the adjusting rope 3 are wound around the rotating drum 10. The adjusting rope is covered with a cooling layer.
[0034] The specific usage and function of this embodiment are as follows:
[0035] In this invention, the inner core of the earplug 2 is made of malleable silicone 4, including but not limited to polydimethylsiloxane, wax pellets, polyvinyl chloride, and silicone clay. Malleable silicone 4 is waterproof and highly malleable. When rubbed by hand, it will slowly expand and gradually return to its original shape, providing good noise reduction. It can reduce excessive noise levels in the environment without affecting normal work, thus protecting hearing. The cooling layer surrounding the inner core of the earplug 2 is made of cooling materials (polyethylene propylene, water, glycerol, hydroxypropyl methylcellulose, patchouli and artemisia extract, and hydrophilic polymer materials). The thickness and softness are moderate, providing both comfortable wear and cooling. This can reduce the damage to hearing caused by the combined effects of high temperature and noise. The material surrounding the cooling layer of the earplug 2 is made of malleable polyethylene foam. It is relatively thin and malleable with water absorption and moisture absorption properties, which helps keep the ear canal dry during the wearing of the earplug 2. The outer surface of the earplug 2 is made of a layer of sterile cotton cloth 7, which can absorb sweat from the ear canal, prevent moisture from causing external auditory canal inflammation, and improve wearing comfort.
[0036] When adjusting the length of the adjusting rope 3, pull out a fixed rod 14 to separate the first fixed groove 15 and the first limiting tooth 16 at one end. At this time, the second fixed groove 13 and the second limiting tooth 17 also separate. Then, rotate the rotating component 9 to drive the rotating cylinder 10 to rotate. When the rotating cylinder 10 rotates, it can wind up the adjusting rope 3. After winding to the appropriate length, the first limiting tooth 16 at the lower end of the fixed rod 14 re-enters the interior of the first fixed groove 15, and the second limiting tooth 17 enters the interior of the second fixed groove 13. At this time, the fixed rod 14 is restricted by the first fixed groove 15 and the first limiting tooth 16 and cannot rotate. The middle part is restricted by the second fixed groove 13 and the second limiting tooth 17. At this time, the rotating component 9 can be restricted and cannot rotate. The adjustment is then completed.
