Description

Technical Field

[0001] This invention relates to the field of ear scraping devices, specifically to a multi-angle adjustable ring-type ear scraping device. Background Technology

[0002] Ear scraping is a component of traditional Chinese medicine's external therapy, involving scraping and stimulating specific areas of the ear for daily health maintenance. With increasing demand, various ear scraping devices have been introduced. Currently, some ear scraping devices have relatively simple angle adjustment structures, limiting the range of adjustment. The complex structure and uneven surface of the ear make it difficult for devices to flexibly adjust in multiple directions to conform to different surface shapes, affecting the scraping operation. Some devices use fixed-size finger rings, which cannot accommodate users with different finger sizes. Rings that are too tight can compress the fingertips, causing soreness and swelling after prolonged use; rings that are too loose result in an unstable connection between the device and the finger, making the scraping head prone to displacement during use. Most devices lack a dedicated force adjustment mechanism, relying primarily on the user's hand strength. Different users have different operating habits, leading to uneven force application. Excessive force may damage the ear skin, while insufficient force fails to achieve the desired stimulation effect. Meanwhile, the process of changing the scraping head in some devices is cumbersome, making it difficult to quickly switch scraping head types according to different operational needs. In view of the above-mentioned problems and defects, those skilled in the art hereby propose a multi-angle adjustable ring-type ear scraping device. Summary of the Invention

[0003] In view of the shortcomings of existing ear scraping devices mentioned in the background art, the present invention provides a technical solution for a multi-angle adjustable ring-type ear scraping device, which solves the problems of limited angle adjustment range, poor finger adaptability and difficulty in controlling scraping force of existing devices.

[0004] The device includes an adjustable ring mechanism, a double-segment ball joint mechanism fixedly connected to the top of the adjustable ring mechanism, and an elastic adjustment mechanism fixed to the top of the double-segment ball joint mechanism. A magnetic scraping head mechanism is fixed to the top of the elastic adjustment mechanism. The adjustable ring mechanism adapts the device to fingers of different sizes, the double-segment ball joint mechanism expands the angle adjustment range of the device, the elastic adjustment mechanism adjusts the scraping force and buffers against overload, and the magnetic scraping head mechanism allows for quick replacement of the scraping head.

[0005] The adjustable ring mechanism includes a connector, Velcro straps fixedly connected to the left and right sides of the connector, and a metal frame embedded inside the Velcro straps. The metal frame provides structural support for the Velcro straps, ensuring that the Velcro straps maintain a stable shape after being wrapped and fixed. The Velcro straps adjust their length using their own Velcro fasteners to accommodate fingers of different sizes.

[0006] The dual-segment ball joint mechanism includes two symmetrically arranged bases, one above the other. Each base has a ball socket fixed at one end close to the other. A spherical silicone sleeve is fixed inside the ball socket, and a ball head is movably connected inside the silicone sleeve. A connecting rod is fixed to the side of each ball head close to the other. The two ball heads are respectively embedded in their corresponding silicone sleeves, forming two independent rotating connection units. The connecting rod connects the two ball heads into a whole, expanding the overall angle adjustment range of the device. The grooves on the inner side of the silicone sleeves increase the contact damping between the ball head and the silicone sleeve, allowing the ball head to maintain its current position after rotating to any angle.

[0007] The elastic adjustment mechanism includes a hollow tube, a rod inserted into the hollow tube, a base plate fixed to the bottom of the outer ring of the rod, a movable sleeve and a cylindrical spring fitted onto the outer ring of the rod, the top end of the cylindrical spring being fixedly connected to the bottom end face of the hollow tube, and locking mechanisms provided on the front and rear sides of the rod. The rod can slide axially inside the hollow tube, the movable sleeve can slide axially along the outer ring of the rod, the cylindrical spring provides axial elastic force, and the locking mechanisms adjust the pre-compression of the cylindrical spring and automatically unlock when the external force exceeds a set value, thus achieving a buffering effect.

[0008] The magnetic scraping head mechanism includes a support plate, a connecting piece located above the support plate, and an ear scraping head fixed to the top of the connecting piece. Magnetic blocks are fixed at the four corners of the top surface of the support plate. The magnetic blocks attract each other with a strong magnet in the bottom cavity of the connecting piece, achieving a detachable connection between the support plate and the connecting piece, allowing for the replacement of different types of ear scraping heads.

[0009] The locking mechanism includes a fixed plate and a hook. A triangular lever is hinged to the outer side of the fixed plate. A pivot is passed through the middle section of the triangular lever, and lead screws are passed through the left and right sections of the pivot. A U-shaped rod that hooks the hook is fixed to the bottom end of the lead screw. The triangular lever rotates around the pivot pin at its bottom end, thereby locking and unlocking the locking mechanism. The lead screw and nut are used to adjust the distance between the fixed plate and the hook, thereby adjusting the pre-compression degree of the cylindrical spring.

[0010] In the above technical solution, preferably: the top surface of the connector is fixedly connected to the bottom surface of the ball socket, and the inner and outer surfaces of the Velcro strap are sewn with Velcro to achieve the wrapping and fixing of the Velcro strap itself.

[0011] In the above technical solution, preferably: the top surface of the ball socket is fixedly connected to the bottom surface of the base plate to realize the transmission between the double-segment ball hinge mechanism and the elastic adjustment mechanism.

[0012] In the above technical solution, preferably, multiple grooves are formed on the inner surface of the spherical silicone sleeve to increase the friction with the ball head and improve the ability to maintain the position after the ball head rotates.

[0013] In the above technical solution, preferably, the bottom end of the cylindrical spring is fixedly connected to the top end face of the movable sleeve, so that the movement of the movable sleeve can directly drive the cylindrical spring to deform.

[0014] In the above technical solution, preferably: a side ring is fixedly connected to the bottom end face of the hollow tube, and the top end of the cylindrical spring is fixedly connected to the bottom surface of the side ring, thereby increasing the contact area between the cylindrical spring and the hollow tube.

[0015] In the above technical solution, preferably: protrusions are fixed on the front and rear side walls of the side ring. When the side ring moves downward, it contacts the top of the triangular lever to unlock the locking mechanism. The upper half of the triangular lever is locked when it is bent upward, and unlocked when it is bent downward, thus realizing the automatic triggering and unlocking of the locking mechanism.

[0016] In the above technical solution, preferably: each of the four corners of the bottom surface of the connecting piece is provided with a cavity for inserting a magnetic block, and a strong magnet piece that magnetically attracts the magnetic block is embedded and fixed inside the cavity, thereby improving the stability of the magnetic connection.

[0017] In the above technical solution, preferably: the inner surface of the fixed plate is fixedly connected to the outer surface of the movable sleeve, and the inner surface of the hook is fixedly connected to the outer surface of the base plate, so that the locking mechanism can connect the movable sleeve and the base plate.

[0018] In the above technical solution, preferably: the outer surface of the fixed plate is fixed with a protrusion that is hinged to the bottom end of the triangular lever through a shaft pin, and nuts are screwed onto the outer ring of the upper and lower through-rotating shaft of the lead screw. By adjusting the position of the nuts, the distance between the fixed plate and the hook is adjusted, thereby allowing the movable sleeve and the base plate to move away from each other and compress the cylindrical spring, thus completing the adjustment of different pre-compression amounts.

[0019] As can be seen from the above technical solution, the present invention provides a multi-angle adjustable ring-type ear scraping device, which, compared with the prior art, has the following beneficial effects:

[0020] This invention utilizes an adjustable ring mechanism to accommodate fingers of varying sizes. The metal skeleton inside the Velcro strap enhances its structural stability, ensuring a more secure connection between the device and the finger. The dual-segment ball joint mechanism employs two independent ball-head rotation structures, expanding the device's angle adjustment range and allowing the ear scraping head to conform to different ear shapes. Grooves on the inner side of the spherical silicone sleeve increase rotational damping, maintaining the adjusted angle. The elastic adjustment mechanism uses a locking mechanism to adjust the pre-compression of the cylindrical spring, setting the scraping force. When the external force exceeds the set value, the locking mechanism automatically unlocks, releasing the pre-compression force of the cylindrical spring and providing a buffering effect. The magnetic scraping head mechanism uses a magnetic connection for quick replacement of different types of ear scraping heads, meeting diverse scraping operation needs. Attached Figure Description

[0030] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be described in further detail below with reference to the embodiments and accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort should fall within the scope of protection of the present invention.

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the embodiments.

[0032] Example:

[0033] This embodiment is a multi-angle adjustable ring-type ear scraping device, including an adjustable ring mechanism 1, a double-segment ball joint mechanism 2 fixedly connected to the top of the adjustable ring mechanism 1, and an elastic adjustment mechanism 3 fixed to the top of the double-segment ball joint mechanism 2. A magnetic scraping head mechanism 4 is fixed to the top of the elastic adjustment mechanism 3. The adjustable ring mechanism 1 includes a connector 1-1, Velcro straps 1-3 fixedly connected to the left and right sides of the connector 1-1, and a metal frame 1-2 embedded inside the Velcro straps 1-3. The top surface of the connector 1-1 is fixedly connected to the bottom surface of the ball socket 2-5 at the bottom of the double-segment ball joint mechanism 2. Velcro straps 1-3 are sewn together on the inner and outer surfaces. The metal frame 1-2 extends along the length of the Velcro straps 1-3 to provide structural support for the Velcro straps 1-3, so that the Velcro straps 1-3 maintain a stable shape after being wrapped and fixed. The Velcro straps 1-3 adjust their length through the Velcro straps on their inner and outer surfaces to accommodate fingers of different thicknesses. The double-segment ball joint mechanism 2 includes two symmetrically arranged bases 2-1. Each base 2-1 has a ball socket 2-5 fixed at one end close to the other. A spherical silicone sleeve 2-2 is fixed inside the ball socket 2-5. A ball head 2-3 is movably connected inside the spherical silicone sleeve 2-2. A connecting rod 2-4 is fixed to the side of the ball head 2-3 close to the other. Both ends of the connecting rod 2-4 are fixedly connected to the end faces of the upper and lower ball heads 2-3, respectively. The top surface of the ball socket 2-5 at the top of the double-segment ball joint mechanism 2 is fixedly connected to the bottom surface of the base plate 3-1 of the elastic adjustment mechanism 3. The spherical silicone sleeve... Multiple grooves are formed on the inner surface of 2-2 to increase the friction between the ball head 2-3 and the ball head 2-3. The two ball heads 2-3 are respectively embedded in the interior of the upper and lower spherical silicone sleeves 2-2, forming two independent rotating connection structures. The connecting rod 2-4 connects the two ball heads 2-3 into a whole, so that the double-segment ball hinge mechanism 2 can rotate in multiple directions, expanding the overall angle adjustment range. The grooves on the inner side of the spherical silicone sleeve 2-2 increase the contact damping between the spherical silicone sleeve 2-2 and the ball head 2-3, so that the ball head 2-3 can maintain its current position after rotating to any angle.

[0034] The elastic adjustment mechanism 3 includes a hollow tube 3-4, a rod 3-6 inserted into the hollow tube 3-4, a base plate 3-1 fixed to the bottom of the outer ring of the rod 3-6, a movable sleeve 3-2 and a cylindrical spring 3-7 fitted onto the outer ring of the rod 3-6, the top of the cylindrical spring 3-7 fixedly connected to the bottom end face of the hollow tube 3-4, locking mechanisms 5 provided on the front and rear sides of the rod 3-6, a side ring 3-5 fixedly connected to the bottom end face of the hollow tube 3-4, the top of the cylindrical spring 3-7 fixedly connected to the bottom surface of the side ring 3-5, the bottom end of the cylindrical spring 3-7 fixedly connected to the top end face of the movable sleeve 3-2, and protrusions 3-3 fixed on the front and rear side walls of the side ring 3-5. When the side ring 3-5 moves downwards, it engages with... The top of the triangular lever 5-3 of the locking mechanism 5 contacts the locking mechanism 5 to unlock it. The upper half of the triangular lever 5-3 is locked when it is bent upward, and unlocked when it is bent downward. The insert rod 3-6 can slide axially inside the hollow tube 3-4. The movable sleeve 3-2 can slide axially on the outer ring of the insert rod 3-6. The cylindrical spring 3-7 is sleeved on the outer ring of the insert rod 3-6, and its two ends are fixedly connected to the side ring 3-5 and the movable sleeve 3-2 respectively. The locking mechanism 5 connects the movable sleeve 3-2 to the base plate 3-1 as a whole. By adjusting the relevant components of the locking mechanism 5, the pre-compression of the cylindrical spring 3-7 can be changed, thereby changing the axial elastic force of the elastic adjustment mechanism 3. The magnetic scraping head mechanism 4 includes a support plate 4-1, a connecting piece 4-3 located above the support plate 4-1, and an ear scraping head 4-4 fixed to the top of the connecting piece 4-3. Magnetic blocks 4-2 are fixed at the four corners of the top surface of the support plate 4-1. The four corners of the bottom surface of the connecting piece 4-3 are provided with chambers for inserting the magnetic blocks 4-2. Each chamber is inlaid with a strong magnet piece that magnetically attracts the magnetic blocks 4-2. The bottom surface of the support plate 4-1 is fixedly connected to the top of the hollow tube 3-4. The shape of the magnetic blocks 4-2 matches the shape of the bottom chamber of the connecting piece 4-3. The magnetic blocks 4-2 and the corresponding strong magnet pieces attract each other, allowing the magnetic blocks 4-2 to be stably inserted into the bottom chamber of the connecting piece 4-3, thus achieving a detachable connection between the support plate 4-1 and the connecting piece 4-3. The connecting piece 4-3 with different ear scraping heads 4-4 can be replaced according to different usage requirements.

[0035] The locking mechanism 5 includes a fixed plate 5-1 and a hook 5-5. A triangular lever 5-3 is hinged to the outer side of the fixed plate 5-1. A rotating shaft 5-6 passes through the middle section of the triangular lever 5-3. A lead screw 5-2 passes through the left and right sections of the rotating shaft 5-6. A U-shaped rod 5-4 that hooks the hook 5-5 is fixed to the bottom end of the lead screw 5-2. The inner surface of the fixed plate 5-1 is fixedly connected to the outer surface of the movable sleeve 3-2. The inner surface of the hook 5-5 is fixedly connected to the outer surface of the base plate 3-1. A protrusion that is hinged to the bottom end of the triangular lever 5-3 via a pin is fixed to the outer surface of the fixed plate 5-1. Nuts are screwed onto the outer ring of the rotating shaft 5-6 through the lead screw 5-2. By adjusting the position of the nuts, the distance between the fixed plate 5-1 and the hook 5-5 is adjusted, thereby allowing the movable sleeve 3-2 to be aligned with the base plate 3-1. The cylindrical spring 3-7 is compressed and the triangular lever 5-3 rotates around the bottom pin. When the upper half of the triangular lever 5-3 rotates upward, the U-shaped rod 5-4 hooks the hook 5-5, keeping a fixed distance between the movable sleeve 3-2 and the base plate 3-1. At this time, the cylindrical spring 3-7 is in a pre-compression state. When the side ring 3-5 is subjected to a downward force and moves downward, the protrusions 3-3 on the front and rear side walls of the side ring 3-5 contact the top bend of the triangular lever 5-3, pushing the upper half of the triangular lever 5-3 to rotate downward, causing the U-shaped rod 5-4 to disengage from the hook 5-5, and releasing the connection between the movable sleeve 3-2 and the base plate 3-1. At this time, the pre-compression force of the cylindrical spring 3-7 is released, and the axial elastic force of the elastic adjustment mechanism 3 changes, achieving a buffering effect when subjected to a large external force. The upper and lower rotating structures of the double-segment ball joint mechanism 2 can rotate independently, allowing the magnetic gua sha head mechanism 4 to be angled in multiple planes to fit the surface shape of different parts of the ear. The Velcro strap 1-3 of the adjustable ring mechanism 1 can be wrapped and fixed according to the thickness of the fingers. The metal frame 1-2 enhances the structural strength of the Velcro strap 1-3 and prevents the Velcro strap 1-3 from being excessively deformed during use. The elastic adjustment mechanism 3 adjusts the pre-compression of the cylindrical spring 3-7 through the locking mechanism 5 to set different axial elastic forces. The magnetic gua sha head mechanism 4 adopts a magnetic connection to realize the quick replacement of the ear gua sha head 4-4 to meet different gua sha operation needs. The locking mechanism 5 automatically unlocks when subjected to an external force exceeding the set value, releasing the pre-compression force of the cylindrical spring 3-7 and changing the elastic force output of the elastic adjustment mechanism 3 to achieve a buffer function when the external force is overloaded.

[0036] Workflow of the technical solution:

[0037] The Velcro strap 1-3 of the adjustable ring mechanism 1 is wrapped around the user's finger. The wrapping length of the Velcro strap 1-3 is adjusted according to the finger thickness. It is secured by the Velcro on the inner and outer surfaces of the Velcro strap 1-3. The metal frame 1-2 provides support for the Velcro strap 1-3, ensuring a relatively stable connection between the device and the finger. The double-segment ball joint mechanism 2 is rotated, causing the two ball heads 2-3 to rotate in multiple directions inside the spherical silicone sleeve 2-2. The connecting rod 2-4 rotates synchronously with the ball heads 2-3. The groove on the inner side of the spherical silicone sleeve 2-2 increases the frictional resistance between the ball heads 2-3 and the spherical silicone sleeve 2-2, maintaining the double-segment ball joint mechanism 2 at the adjusted angle, thus driving the magnetic scraper. When the scraping head mechanism 4 moves to the ear area to be scraped, and the elasticity of the elastic adjustment mechanism 3 is adjusted, the upper half of the triangular lever 5-3 is pulled upwards to the locked state. The U-shaped rod 5-4 hooks the hook 5-5. The screw 5-2 passes through the nut on the outer ring of the rotating shaft 5-6, and the position of the screw 5-2 on the rotating shaft 5-6 is adjusted. This changes the relative distance between the fixed plate 5-1 and the hook 5-5, causing the movable sleeve 3-2 to move axially along the insertion rod 3-6, compressing or releasing the cylindrical spring 3-7. The pre-compression of the cylindrical spring 3-7 is adjusted to complete the setting of the scraping force. During the scraping process, the user moves their fingers to move the entire device, and the ear scraping head 4-4 contacts the ear skin and generates a force. During sliding, the hollow tube 3-4 and the insertion rod 3-6 slide relative to each other axially. The elastic force generated by the cylindrical spring 3-7 is transmitted through the hollow tube 3-4 to the magnetic scraping head mechanism 4, acting on the surface of the ear skin. When the external force applied to the ear scraping head 4-4 exceeds the set value, the hollow tube 3-4 drives the side ring 3-5 to move towards the base plate 3-1. The protrusions 3-3 on the front and rear side walls of the side ring 3-5 contact the top bend of the triangular bend rod 5-3, pushing the triangular bend rod 5-3 to rotate downward around the bottom pin as the fulcrum. This causes the U-shaped rod 5-4 to disengage from the hook 5-5, and the locking mechanism 5 releases the restriction on the movable sleeve 3-2. The pre-compression force of the cylindrical spring 3-7 is released, and the movable sleeve 3- 2. Slide the insert rod 3-6 upwards. The axial elastic force of the elastic adjustment mechanism 3 changes, achieving buffering under external force. When the ear scraping head 4-4 needs to be replaced, pull the connecting piece 4-3 upwards to overcome the attraction between the magnetic block 4-2 and the strong magnet in the bottom cavity of the connecting piece 4-3, so that the magnetic block 4-2 is separated from the bottom cavity of the connecting piece 4-3. Remove the original connecting piece 4-3 and ear scraping head 4-4. Align the bottom cavity of the new connecting piece 4-3 with the magnetic block 4-2 on the top of the support plate 4-1. The magnetic block 4-2 is inserted into the corresponding cavity and magnetically attracted to the strong magnet, completing the replacement of the ear scraping head 4-4. When using it again, bend the triangular lever 5-3 to the locked state.
