Description

Technical Field

[0001] This invention relates to the field of headphone cleaning technology, and more particularly to a headphone case. Background Technology

[0002] As an important accessory in electronic products, headphones are commonly used to connect to mobile phones, computers, and other devices. To achieve a better user experience, various types of wireless headphones have emerged on the market. Among these, in-ear headphones have become increasingly popular, leading to a growing demand for headphone cleaning among users.

[0003] Currently, most methods for cleaning in-ear headphones still rely on manual cleaning, using a small brush or cleaning cloth. Because manual cleaning is tedious and time-consuming, automatic cleaning devices have emerged on the market. These devices typically use a motor-driven cleaning brush to clean the headphones. However, since these methods apply force to the headphones from the outside to remove dirt, this dirt can easily be affected by the cleaning brush and enter the headphones through the sound outlet, resulting in a deterioration in sound quality.

[0004] In view of the above-mentioned shortcomings, it is necessary to provide a new headphone case. Summary of the Invention

[0048] This invention proposes an earphone case designed to solve the problem that current earphone cleaning methods, when using a cleaning brush, can easily allow dirt to enter the earphone through the sound outlet, thus affecting the sound quality.

[0049] Please refer to Figure 1 , Figure 3 and Figure 5 The earphone case includes a case body 1, a vacuuming mechanism 2, and a driving mechanism 3. The case body 1 has a receiving cavity 11 for accommodating earphones and a movable cavity 12 communicating with the receiving cavity 11. The vacuuming mechanism 2 includes a cleaning chamber 21, a dust chamber 22, and a fan 23. The cleaning chamber 21 is located in the movable cavity 12 and is slidably connected to the cavity wall of the movable cavity 12. The dust chamber 22 is installed in the case body 1 and is connected to the cleaning chamber 21 through a duct 221. The cleaning chamber 21 has an adsorption port 211 corresponding to the receiving cavity 11. The fan 23 is located between the adsorption port 211 and the dust chamber 22. The driving mechanism 3 is installed in the case body 1 and includes a transmission component 31 and a displacement driving component 32. The transmission component 31 is connected to the cleaning chamber 21, and the displacement driving component 32 is used to drive the cleaning chamber 21 closer to or away from the receiving cavity 11 through the transmission component 31.

[0050] The earphone case of the present invention includes a case body 1, a dust collection mechanism 2 and a drive mechanism 3 both disposed within the case body 1. The case body 1 has a receiving cavity 11 for accommodating earphones and a movable cavity 12 communicating with the receiving cavity 11. The earphones can be in-ear earphones. The cleaning chamber 21 of the dust collection mechanism 2 is located within the movable cavity 12 and is slidably connected to the cavity wall of the movable cavity 12. The dust chamber 22 is connected to the cleaning chamber 21 through a duct 221. The transmission component 31 of the drive mechanism 3 is connected to the cleaning chamber 21. When the earphones are placed in the receiving cavity 11, the displacement drive component 32 of the drive mechanism 3 drives the cleaning chamber 21 to approach the receiving cavity 11 through the transmission component 31, so that the suction port 211 on the cleaning chamber 21 approaches the earphones inside the receiving cavity 11. The fan 23 sucks the dirt on the earphones into the dust chamber 22 through the suction port 211. The earphone case of the present invention drives the cleaning chamber 21 to approach the earphone in the receiving cavity 11 through the driving mechanism 3. The fan 23 sucks the dirt on the earphone in the receiving cavity 11 through the cleaning chamber 21 to the dust chamber 22. No cleaning brush is required, which avoids dirt entering the earphone and affecting the sound quality. Moreover, no manual cleaning of the earphone is required, which is convenient and provides users with a better user experience.

[0051] In one embodiment, the housing 1 has two oppositely arranged receiving cavities 11, which are a first cavity for receiving the left earphone and a second cavity for receiving the right earphone. A movable cavity 12 is located between the first and second cavities, and its two ends are respectively connected to the first and second cavities. The number of cleaning chambers 21 is the same as the number of receiving cavities 11 and they correspond one-to-one. Both cleaning chambers 21 are connected to the dust chamber 22 through a duct 221. Both cleaning chambers 21 are connected to the transmission assembly 31. The displacement drive 32 is used to drive the two cleaning chambers 21 to move closer to or further away from the corresponding receiving cavity 11 through the transmission assembly 31. The movable cavity 12 is located between the first and second chambers, with its two ends connected to the first and second chambers respectively. Both cleaning chambers 21 are located within the movable cavity 12 and connected to the transmission assembly 31. When the left earphone is placed in the first chamber and the right earphone in the second chamber, the displacement drive 32, via the transmission assembly 31, moves the two cleaning chambers 21 closer to their corresponding receiving chambers 11. One cleaning chamber 21 approaches the first chamber and cleans the left earphone located in the first chamber using a fan 23, while the other cleaning chamber 21 approaches the second chamber and cleans the right earphone located in the second chamber using a fan 23. After cleaning, the displacement drive 32, via the transmission assembly 31, moves the two cleaning chambers 21 away from their respective receiving chambers 11, thus not affecting the removal of the earphones. The displacement drive 32 can be a motor, allowing simultaneous cleaning of both the left and right earphones using the same displacement drive 32. This saves energy in the earphone case and also simplifies its structure and reduces its size.

[0052] Furthermore, please combine Figure 1As shown, the two cleaning chambers 21 are the first cleaning chamber and the second cleaning chamber, respectively. The first cleaning chamber is provided with a first rack 212, and the second cleaning chamber is provided with a second rack 213. The first rack 212 is located above the second rack 213, and the first rack 212 and the second rack 213 are respectively slidably connected to the top wall and bottom wall of the movable cavity 12. The transmission assembly 31 includes a transmission gear connected to the displacement drive member 32. The transmission gear is located between the first rack 212 and the second rack 213 and meshes with the first rack 212 and the second rack 213. The tooth surface of the first rack 212 is set downwards, and the tooth surface of the second rack 213 is set upwards. The tooth surface of the first rack 212 is located above the tooth surface of the second rack 213. The transmission gear is located between the first rack 212 and the second rack 213 and meshes with the first rack 212 and the second rack 213. When the displacement drive 32 drives the transmission gear to rotate, the transmission gear drives the first rack 212 to move closer to or away from the first chamber, and at the same time drives the second rack 213 to move closer to or away from the second chamber.

[0053] Additionally, please combine Figure 1 , Figure 4 , Figure 5 As shown, in one embodiment, the top wall of the active cavity 12 is provided with two corresponding first vertical walls 121. The extension direction of the two first vertical walls 121 is consistent with the movement direction of the cleaning chamber 21. The top of the first rack 212 is provided with a slider 2121. The two first vertical walls 121 form a first sliding groove for the slider 2121 to be inserted and slide. The bottom of the two first vertical walls 121 extends into the first sliding groove to form a support wall. The side of the slider 2121 corresponding to the support wall is recessed to form a groove for the support wall to be inserted. The slider 2121 can be hung in the first sliding groove by the support of the two support walls. When the first rack 212 approaches or moves away from the first chamber, the first rack 212 slides in the first sliding groove through the slider 2121, so as to smoothly approach or move away from the first chamber. Furthermore, the bottom wall of the movable cavity 12 is provided with two corresponding second vertical walls 122. The two second vertical walls 122 form a second sliding groove for the second rack 213 to be inserted and slide. When the second rack 213 approaches or moves away from the second cavity, the bottom of the second rack 213 is inserted into the second sliding groove and slidably connected with the groove wall of the second sliding groove. Under the guidance of the second sliding groove, the second rack 213 can smoothly approach or move away from the second cavity.

[0054] In addition, to prevent the first rack 212 and the second rack 213 from exceeding their movement limits, the top wall of the movable cavity 12 is provided with a first end wall (not shown) to hinder the movement of the first rack 212, or the bottom wall of the movable cavity 12 is provided with a second end wall 123 to hinder the movement of the second rack 213. If the top wall of the movable cavity 12 is provided with a first end wall, when the first rack 212 moves to its extreme positions at both ends, both ends of the first rack 212 are blocked by the first end wall, thereby limiting the position of the first rack 212. By limiting the rotation of the transmission gear, the position of the second rack 213 can be limited. Similarly, if the bottom wall of the movable cavity 12 is provided with a second end wall 123, the second end wall 123 can hinder the movement of the second rack 213 and the first rack 212.

[0055] In this regard, please combine Figure 4 , Figure 5 As shown, the bottom of the second rack 213 is provided with a plurality of sliding strips 2131 that slide in cooperation with the groove wall of the second groove. In order to enable the second rack 213 to slide smoothly in the second groove, the bottom of the second rack 213 is provided with a plurality of sliding strips 2131 at intervals. To reduce friction, the outer contour of the cross section of the sliding strips 2131 can be arc-shaped.

[0056] Furthermore, please combine Figure 3 , Figure 4 As shown, in order to achieve multiple functions, the opposite sides of the box 1 are respectively recessed to form a first mounting groove 13 and a second mounting groove 14. The first mounting groove 13 and the second mounting groove 14 are respectively located on opposite sides of the movable cavity 12, and the bottom wall of the first mounting groove 13 and the bottom wall of the second mounting groove 14 are provided with through holes communicating with the movable cavity 12. The dust bin 22 is installed in the first mounting groove 13, and the displacement drive component 32 is installed in the second mounting groove 14. For ease of assembly, the dust chamber 22 and the displacement drive component 32 can be installed on opposite sides of the movable cavity 12, that is, the two sides of the box body 1 are respectively recessed to form the first mounting groove 13 and the second mounting groove 14. The first mounting groove 13 and the second mounting groove 14 are respectively located on opposite sides of the movable cavity 12. During installation, the cleaning chamber 21 is first installed in the movable cavity 12, then the dust chamber 22 is installed in the first mounting groove 13, and finally the assembled transmission gear and the displacement drive component 32 are inserted from the second mounting groove 14, so that the upper end and the lower end of the transmission gear mesh with the first rack 212 and the second rack 213 respectively.

[0057] Furthermore, please combine Figure 4As shown, in one embodiment, the headphone case further includes a light box 4, which contains an indicator light 41. The light box 4 is installed in the second mounting slot 14 and is located on the side of the displacement drive member 32 near the opening of the second mounting slot 14. A light hole corresponding to the indicator light 41 is opened on the side of the light box 4 facing the opening of the second mounting slot 14. When the headphone case is being cleaned, the indicator light 41 illuminates. If the cleaning process is abnormal, the indicator light 41 can flash to alert the user, who can then check accordingly. For example, if the dust chamber 22 is full, it needs to be emptied. After the cleaning process is completed, the indicator light 41 turns off.

[0058] Additionally, please combine Figure 3 , Figure 5 As shown in the above embodiment, the dust bin 22 includes a bin body 222 and a bin cover 223 that are detachably connected to each other. The bin body 222 has a dust chamber 2221 and an inlet and an outlet that are both connected to the dust chamber 2221. A fan 23 is installed inside the dust chamber 2221. The inlet is connected to the end of the air duct 221 away from the cleaning bin 21. The air inlet of the fan 23 is connected to the inlet, and the air outlet of the fan 23 is connected to the outlet. The bin cover 223 is placed over the outlet. To facilitate cleaning the dust bin 22, the dust bin 22 can be configured with a bin body 222 and a bin cover 223 that are detachably connected to each other. When it is necessary to clean the dust bin 22, simply open the bin cover 223. The bin body 222 and the bin cover 223 can be rotatably connected on one side and snapped together on the other side, or both sides can be snapped together.

[0059] In one embodiment, please refer to Figures 10 to 16As shown, the cover 223 is provided with a locking block 2231, and the cavity wall of the dust chamber 2221 is provided with a fixing block 2222. The fixing block 2222 is located near the outlet, and the fixing block 2222 is recessed on the side facing the outlet to form a sliding groove 2223. The sliding groove 2223 is provided with an elastic clamp 2224, an elastic element 2225 and a pull rod 2226. The elastic clamp 2224 is slidably connected to the side wall of the sliding groove 2223 and is used to clamp the locking block 2231. The elastic element 2225 abuts against the bottom wall of the sliding groove 2223. The side wall of the sliding groove 2223 is provided with a shaped locking groove 2227. One end of the pull rod 2226 is rotatably connected to the elastic clamp 2224, and the other end of the pull rod 2226 is inserted into the shaped locking groove 2227 and slidably connected to the wall of the shaped locking groove 2227. When it is necessary to engage the cover 223 with the dust chamber 22 body 222, simply place the cover 223 over the outlet of the body 222, insert the locking block 2231 on the cover 223 into the elastic clip 2224, and press the elastic clip 2224 so that the elastic clip 2224 slides in the sliding groove 2223. The end of the pull rod 2226, which is rotatably connected to the elastic clip 2224, away from the elastic clip 2224, slides in the irregular groove 2227 until the end of the pull rod 2226 away from the elastic clip 2224 slides to a preset position. At this point, the elastic element 2225 is in a compressed state. The elastic element 2225 can be a compression spring. The elastic clip 2224 is locked in the sliding groove 2223 and the locking block 2231 is locked in place, thereby engaging the cover 223 with the body 222.

[0060] Furthermore, please combine Figure 13As shown, the irregularly shaped slot 2227 has slot walls at four different positions. The pull rod abuts against one of the slot walls. The four positions are the first position 222a, the second position 222b, the third position 222c, and the fourth position 222d. When the locking block 2231 is not pressing the elastic clip 2224, the pull rod 2226 abuts against the slot wall at the second position 222b, and the elastic element 2225 is in a state of no deformation. When the locking block 2231 is engaged with the elastic clip 2224, the pull rod 2226 abuts against the slot wall at the second position 222b, and the elastic element 2225 is in a state of no deformation. After clamp 2224 is engaged, pull rod 2226 abuts against the groove wall at the first position 222a, and the spring is in a compressed state. When the locking block 2231 engaged with the elastic clamp 2224 is pressed, pull rod 2226 abuts against the groove wall at the third position 222c, and when the locking block 2231 is released, pull rod 2226 abuts against the groove wall at the fourth position 222d. Elastic element 2225 is used to push the elastic clamp 2224 to release the locking block 2231. Assembly principle of the press spring switch: Utilizing the self-locking characteristic of the elastic press button, the opening and closing of the compartment cover 223 can be achieved by pressing to clean the compartment body 222. The second position 222b is the position where the locking block 2231 of the compartment cover 223 is not pressed into the compartment body 222, and the post on pull rod 2226 is in the irregular groove 2227, and the spring is not compressed. The first position 222a is when the latch 2231 of the cover 223 is pressed into the compartment 222, and the post on the lever 2226 is in the irregular groove 2227. After releasing the press, the elastic element 2225 rebounds, achieving locking. The third position 222c is when the cover 223 is pressed again, and the post on the lever 2226 is in the irregular groove 2227. After releasing the press, the post on the lever 2226 moves to the fourth position 222d in the irregular groove 2227, releasing the compressive force of the elastic element 2225 and popping out the cover 223.

[0061] Additionally, please combine Figure 8 , Figure 9As shown, the box body 1 includes a lid 15 and a body 16. The body 16 has a receiving cavity 11 and a movable cavity 12. The receiving cavity 11 has an upward-facing opening. The lid 15 is rotatably connected to the body 16 and is used to open and close the opening. The headphone box also includes a controller and a sensor 5 disposed in the body 16. The sensor 5 is used to sense the lid 15. The sensor 5, the displacement drive 32, and the fan 23 are all communicatively connected to the controller. Sensor 5 can be a photosensitive sensor. The photosensitive sensor and displacement drive 32 are connected as one unit via the main board. The displacement drive 32 is a motor. When the cover 15 is closed, the photosensitive sensor can no longer detect light.
