Description

Technical Field

[0001] This application relates to the field of ear cover technology, and more particularly to a heat dissipation ear cover. Background Technology

[0002] Ear tips mainly consist of a support and a protective cover. Their primary function is to protect the ears in winter, and over time they have evolved into fashion accessories. However, with societal progress, people are paying increasing attention to their appearance, materials, and overall value. Advanced technology has been developed in terms of materials, styles, and functionality, and brand philosophy is also emphasized. Ear tips, placed on headphones, not only ensure sound quality but also provide a comfortable wearing experience.

[0003] The published patent, CN212876088U, describes a novel graphene heat-dissipating earcup. The technical solution includes a leather case, dustproof mesh, delivery pipe, air inlet pipe, fixing strap, fan device, air outlet pipe, annular support frame, graphene annular sheet, sponge layer, lithium battery, fan, USB port, and fan blades. The flat, concave portion of the leather case is clamped to the inner wall of the earphone earpiece, and the fan device is placed in a slot on the earpiece surface. The graphene dissipates heat from the inside of the earcup, allowing heat to enter the inner cavity of the support frame. Turning on the fan creates airflow within the annular support frame, carrying away internal heat. The combination of these two elements provides a more comfortable wearing environment.

[0004] When the above devices are implemented, it is not possible to regulate the internal temperature of the devices in winter. Since the ear tips are used together with the headphones, and the headphones are used in both winter and summer, it is too cold to wear them directly in winter. The inability to raise the temperature of the devices will affect the user's comfort when wearing them. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a heat dissipation ear cover, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0006] To achieve the above objectives, this application adopts the following technical solution: a heat dissipation ear cover, including a shell, a side plate installed on the outer side of the shell, a button one and a button two fixedly installed on the outer side of the side plate, a USB interface opened on the inner wall of the side plate, a silent motor fixedly installed on the side of the side plate away from the button one and the button two, a fan fixedly connected to the power output shaft of the silent motor, a fixing frame fixedly installed on the inner side of the side plate, a heating tube fixedly connected to the side of the fixing frame near the fan, a temperature sensor fixedly installed on the side of the fixing frame away from the heating tube, and five arc-shaped grooves annularly opened on the side of the shell away from the side plate, with five arc-shaped blocks inserted into the inner walls of the five arc-shaped grooves, and a comfort pad fixedly installed on the outer side of the five arc-shaped blocks.

[0007] In a preferred embodiment, two rotating holes are symmetrically opened on the outer side of the outer shell. A rotating frame is rotatably connected to the inner wall of the rotating hole, and a U-shaped elastic frame is fixedly connected to the top of the rotating frame, so that the angle of the outer shell can be adjusted by rotating the frame, thereby improving the versatility of wearing it.

[0008] In a preferred embodiment, the outer edge of the side plate is provided with three slots evenly spaced, and the outer shell is provided with three threaded holes evenly spaced on the side of the side plate. The inner walls of the three slots and threaded holes are threaded with three bolts, so that the connection between the outer shell and the side plate can be achieved by using the three bolts in conjunction with the slots and threaded holes, ensuring the stability of the connection and installation and ensuring that it will not easily come apart.

[0009] In a preferred embodiment, the inner wall of the fixed frame is provided with several air outlet slots. The inner cavity of the outer shell is equipped with a storage battery, which is electrically connected to the USB interface. The silent motor, heating element, arc block, and temperature sensor are all electrically connected to the storage battery. The silent motor is electrically connected to button one, so that the charging cable can be plugged into the inner wall of the USB interface to charge the storage battery. This battery can then be used to supply power to the silent motor, heating element, arc block, and temperature sensor to ensure their normal operation. Pressing button one can start and stop the silent motor.

[0010] In a preferred embodiment, both the fan and the fixed frame are made of heat-resistant materials, which ensures that the heat generated by the heating element during operation will not affect the fan and the fixed frame, and thus will not cause damage.

[0011] In a preferred embodiment, the outer shell is made of magnetic material, and the arc-shaped block is electrically connected to the second button, so that the arc-shaped block can be stably adsorbed and positioned on the inner wall of the arc-shaped groove by using the magnetic attraction principle, thereby realizing the connection between the comfort pad and the outer shell. After the magnetism of the arc-shaped block is eliminated, the comfort pad can be easily removed from the outer wall of the outer shell for cleaning, maintenance and replacement.

[0012] In a preferred embodiment, the comfort pad is made of memory foam, and the side of the comfort pad near the arc-shaped block is closely fitted to the outer wall of the shell, so that the comfort pad fits closely to the user's ear when wearing the device, thereby improving the user's comfort when wearing it.

[0013] In a preferred embodiment, the comfort pad has several through holes in its center, allowing the airflow generated by the silent motor and fan to be discharged to the outside through the air outlet and through holes, thus coming into contact with the user's skin and achieving heat dissipation.

[0014] The beneficial effects of this application are:

[0015] 1. This heat dissipation ear cover uses a temperature sensor to monitor the temperature of the inner cavity of the shell in real time. Based on the detected temperature, the heating tube can be driven to operate, thereby adjusting the inner cavity of the shell to a high temperature in winter to achieve heat transfer and ensure that the user's ears do not feel cold when wearing it, thus improving comfort.

[0016] 2. This type of heat dissipation ear cover allows the side plate to be separated from the outer shell by removing three bolts, thus enabling the silent motor and fan to be taken out for external inspection and maintenance. At the same time, pressing button two can eliminate the magnetism of the arc block, making it easy to remove the comfort pad from the outer wall of the outer shell for cleaning, maintenance, and replacement.

[0024] Reference Figure 1-5A heat dissipation ear cover includes a shell 1, a side plate 4 installed on the outer side of the shell 1, a button 8 and a button 9 fixedly installed on the outer side of the side plate 4, a USB interface 10 opened on the inner wall of the side plate 4, a silent motor 11 fixedly installed on the side of the side plate 4 away from the button 8 and the button 9, a fan 12 fixedly connected to the power output shaft of the silent motor 11, a fixing frame 14 fixedly installed on the inner side of the side plate 4, a heating tube 13 fixedly connected to the side of the fixing frame 14 near the fan 12, a temperature sensor 16 fixedly installed on the side of the fixing frame 14 away from the heating tube 13, and five arc-shaped grooves 17 are opened in a ring shape on the side of the shell 1 away from the side plate 4, and five arc-shaped blocks 18 are inserted into the inner wall of the five arc-shaped grooves 17, and a comfort pad 19 is fixedly installed on the outer side of the five arc-shaped blocks 18.

[0025] See Figure 1 and Figure 5 Two rotating holes 21 are symmetrically opened on the outer side of the outer shell 1. A rotating frame 2 is rotatably connected to the inner wall of the rotating hole 21. A U-shaped elastic frame 3 is fixedly connected to the top of the rotating frame 2, so that the angle of the outer shell 1 can be adjusted by rotating frame 2, thereby improving the versatility of wearing.

[0026] See Figure 2 The outer edge of the side plate 4 is evenly provided with three slots 5, and the outer shell 1 is evenly provided with three threaded holes 7 on the side near the side plate 4. The inner walls of the three slots 5 and the threaded holes 7 are threaded with three bolts 6, so that the connection between the outer shell 1 and the side plate 4 can be achieved by using the three bolts 6 in conjunction with the slots 5 and the threaded holes 7, ensuring the stability of the connection and installation and ensuring that it will not easily come apart.

[0027] See Figure 4 The inner wall of the fixed frame 14 is provided with several air outlet slots 15. The inner cavity of the outer shell 1 is equipped with a storage battery, which is electrically connected to the USB interface 10. The silent motor 11, heating tube 13, arc block 18 and temperature sensor 16 are all electrically connected to the storage battery. The silent motor 11 is electrically connected to the button 8, so that the charging cable can be plugged into the inner wall of the USB interface 10 to charge the storage battery, which can then be used to supply power to the silent motor 11, heating tube 13, arc block 18 and temperature sensor 16 to ensure their normal operation. Pressing the button 8 can be used to start and stop the silent motor 11.

[0028] See Figure 4 Both the fan 12 and the fixed frame 14 are made of heat-resistant materials, which ensures that the heat generated by the heating tube 13 during operation will not affect the fan 12 and the fixed frame 14, and thus will not cause damage.

[0029] See Figure 5The outer shell 1 is made of magnetic material. The arc-shaped block 18 is electrically connected to the button 9, so that the arc-shaped block 18 can be stably attracted and positioned on the inner wall of the arc-shaped groove 17 by using the magnetic attraction principle, thereby realizing the connection between the comfort pad 19 and the outer shell 1. After the magnetism of the arc-shaped block 18 is eliminated, the comfort pad 19 can be easily removed from the outer wall of the outer shell 1 for cleaning, maintenance and replacement.

[0030] See Figure 5 The comfort pad 19 is made of memory foam. The side of the comfort pad 19 near the arc block 18 is closely fitted to the outer wall of the outer shell 1, so that the comfort pad 19 can fit closely to the user's ear when wearing the device, thus improving the user's comfort when wearing it.

[0031] See Figure 5 The comfort pad 19 has several through holes 20 in the middle, so that the air generated by the silent motor 11 and the fan 12 can be discharged to the outside through the air outlet 15 and the through holes 20 and come into contact with the user's skin to achieve heat dissipation.

[0032] Working principle: When using this device, the silent motor 11 is driven to rotate the fan 12, which generates airflow that is discharged to the outside through the air outlet 15 and through the through hole 20 to contact the user's skin for heat dissipation. At the same time, the temperature sensor 16 can monitor the temperature of the inner cavity of the outer shell 1 in real time, and the heating tube 13 can be driven to operate according to the detected temperature. In winter, the inner cavity of the outer shell 1 can be adjusted to a high temperature to achieve heat transfer and ensure that the user's ears do not feel cold when wearing it, thus improving comfort. The side plate 4 can be separated from the outer shell 1 by removing the three bolts 6, and the silent motor 11 and fan 12 can be taken out for external inspection and maintenance. At the same time, the comfort pad 19 can be easily removed from the outer wall of the outer shell 1 by pressing the second button 9 to eliminate the magnetism of the arc block 18, and then the comfort pad 19 can be cleaned, maintained and replaced.
