[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0021] See also Figure 1-Figure 9 As shown, an ultrasonic acupuncture device and a method of use, including an acupuncture device body 1, a connector 2 is fixedly connected to the bottom end of the acupuncture device body 1, and an acupuncture head 3 is arranged at the bottom end of the connector 2; a protective mechanism is arranged at the bottom end of the acupuncture device body 1, the protective mechanism is used to protect the acupuncture head 3, a connecting mechanism is arranged between the connector 2 and the acupuncture head 3, and the connecting mechanism is used to quickly install, disassemble and replace the acupuncture head 3; the connecting mechanism includes a positioning block 41, the positioning block 41 is fixedly connected to the inner wall of the connector 2, positioning grooves 42 are provided on both sides of the connector 2, a connecting groove 43 is provided on the positioning block 41, the positioning block 41 is inserted into the inside of the positioning groove 42, the connecting groove 43 is engaged with a connecting block 44, and the connecting block 44 is slidably connected to a storage Cavity 45, the storage cavity 45 is opened on the inner wall of the positioning block 41, and a second spring 46 is arranged inside the storage cavity 45. A release component is arranged at the bottom end of the connecting block 44, and the release component is used to release the engagement between the connecting block 44 and the connecting groove 43. The release component includes a top block 49, and the top block 49 is arranged inside the connecting groove 43. A third spring 50 is arranged at the bottom end of the top block 49. A moving groove 51 is opened at a position near the top on the outside of the connecting head 2, and a pushing ring 52 is threadedly connected to the moving groove 51. The right side of the top block 49 extends to the inside of the moving groove 51, and an anti-slip pattern is opened on the outside of the pushing ring 52. The top end of the third spring 50 is fixedly connected to the bottom end of the top block 49, and the bottom end of the third spring 50 is fixedly connected to the inner wall of the connecting groove 43.

[0022] During operation, when the acupuncture head 3 is to be removed for replacement, the push ring 52 is first rotated to make the push ring 52 move inside the moving groove 51, and the top block 49 is pushed upward so that the top block 49 pulls the third spring 50 to produce elastic deformation. At the same time, the top end of the top block 49 pushes the inclined surface of the connecting block 44, and pushes the connecting block 44 to move inside the storage cavity 45 to release the state of being engaged with the connecting groove 43. When the push ring 52 is rotated upward to the limit, the top block 49 completely pushes the connecting block 44 out of the connecting groove 43. At this time, the connection between the acupuncture head 3 and the connecting head 2 is released. The pulling force of the third spring 50 keeps the top block 49 at the bottom of the connecting groove 43 without being affected by external force, thereby avoiding the engagement between the connecting block 44 and the connecting groove 43. When the acupuncture head 3 is to be installed, the positioning block 41 is first aligned with the positioning groove 42, and then the acupuncture head 3 is pushed toward the connecting head 2, so that the positioning block 41 is inserted into the interior of the positioning groove 42. When the positioning block 41 is inserted into the interior of the positioning groove 42, the positioning block 41 squeezes the inclined surface on the connecting block 44, so that the connecting block 44 moves toward the interior of the storage cavity 45 under the action of the squeezing force and squeezes the second spring 46, so that the second spring 46 produces elastic deformation. When the positioning block 41 is completely inserted into the interior of the positioning groove 42, the squeezing force of the positioning block 41 on the connecting block 44 disappears. At this time, the connecting block 44 automatically returns to its original position under the action of the restoring force of the second spring 46, and engages with the connecting groove 43, thereby fixing the acupuncture head 3.

[0023] Furthermore, a second sliding block 47 is fixedly connected to the top of the inner wall of the storage chamber 45, and the second sliding block 47 is slidably connected to a second sliding groove 48, and the second sliding groove 48 is opened at the top of the connecting block 44; the second spring 46 is fixedly connected to the connecting block 44 on the side close to the connecting block 44, and the second spring 46 is fixedly connected to the inner wall of the storage chamber 45 on the side away from the connecting block 44; when the connecting block 44 moves, the second sliding block 47 fixedly connected to the inner wall of the storage chamber 45 slides synchronously inside the second sliding groove 48, and the combination of the second sliding block 47 and the second sliding groove 48 has the effect of limiting the moving distance of the connecting block 44, thereby preventing the connecting block 44 from moving excessively and escaping from the inside of the storage chamber 45 under the action of the restoring force of the storage chamber 45.

[0024] Furthermore, the protection mechanism includes a protective sleeve 21, which is arranged on the outer side of the bottom end of the acupuncture device body 1, and a baffle ring 22 is fixedly connected to the outer side of the acupuncture device body 1 near the top. A fixing groove 23 is opened on the inner wall of the protective sleeve 21, and a fixing block 24 is engaged with the fixing groove 23. The fixing block 24 is slidably connected with an active cavity 25. The active cavity 25 is opened at positions near the bottom end on both sides of the acupuncture device body 1, and a first spring 26 is arranged inside the active cavity 25. A pressing block 27 is fixedly connected to the top of the fixing block 24, and baffles 30 are arranged on both sides of the baffle ring 22. The bottom end of the baffle 30 near the baffle ring 22 is fixedly connected with a first sliding block 31, and the first sliding block 31 is slidably connected with a first sliding groove 32. The first sliding groove 32 is opened on both sides of the baffle ring 22, and both sides of the inner wall of the first sliding groove 32 are fixedly connected with a clamping block 33, and the clamping block 33 is made of rubber.

[0025] During operation, when the protective cover 21 is to be removed and the acupuncture device body 1 is to be used, the baffle plate 30 is first pushed to drive the first sliding block 31 fixedly connected to the baffle plate 30 to move synchronously, so that the first sliding block 31 squeezes the rubber block 33 glued to the inner wall of the first sliding groove 32, so that the block 33 is elastically deformed, and then the block 33 is released from the state of being engaged with the first sliding block 31, and the fixation of the baffle plate 30 and the first sliding block 31 is released. At this time, the baffle plate 30 drives the first sliding block 31 in the first sliding groove 32. When the first sliding block 31 slides to the limit in the first sliding groove 32, the first sliding block 31 engages with the block 33 on the other side of the inner wall of the first sliding groove 32, and the position is fixed. At this time, the baffle 30 releases the blocking of the pressing block 27. At this time, the pressing block 27 is pressed toward the acupuncture device body 1, so that the pressing block 27 drives the fixedly connected fixed block 24 to move synchronously, so that the fixed block 24 is released from the state of being engaged with the fixed groove 23. At this time, the protective cover 21 automatically falls down under the action of gravity and is released. For the protection of the connector 2 and the acupuncture head 3, when the protective cover 21 is installed after the use of the acupuncture device body 1, the protective cover 21 is firstly placed on the outside of the connector 2 and the acupuncture head 3, and then the protective cover 21 is pushed upward, so that the inner wall of the protective cover 21 squeezes the inclined surface provided on the fixing block 24, so that the fixing block 24 moves toward the inside of the active cavity 25 under the action of the squeezing force, and squeezes the first spring 26, so that the first spring 26 produces elastic deformation under the action of the squeezing force, when the protective cover 2 When the top of the first spring 26 abuts against the retaining ring 22, the inner wall of the protective sleeve 21 no longer squeezes the fixing block 24. At this time, the fixing block 24 returns to its original position under the action of the restoring force of the first spring 26 and engages with the fixing groove 23, thereby fixing the protective sleeve 21. Then, the baffle plate 30 is pushed to return to its original position so that the baffle plate 30 blocks the pressing block 27, thereby preventing the pressing block 27 from driving the fixing block 24 to release the engagement with the fixing groove 23 due to an accidental collision, causing the protective sleeve 21 to fall off. At this point, the installation of the protective sleeve 21 is completed.

[0026] Furthermore, the pressing block 27 is designed in an "L" shape, and the side of the first spring 26 close to the fixed block 24 is fixedly connected to the fixed block 24, and the side of the first spring 26 away from the fixed block 24 is fixedly connected to the inner wall of the movable cavity 25; a sliding groove 28 is provided at the top of the pressing block 27, and a slider 29 is slidably connected inside the sliding groove 28, and the top of the slider 29 is fixedly connected to the inner wall of the movable cavity 25; when the pressing block 27 moves, the slider 29 fixedly connected to the inner wall of the movable cavity 25 slides synchronously inside the sliding groove 28, and the movement of the pressing block 27 and the first spring 26 is guided by the action of the sliding groove 28 and the slider 29, so that the pressing block 27 and the first spring 26 are more stable when moving.

[0027] Furthermore, a method for using an ultrasonic acupuncture device comprises the following steps: S1: Release the protection mechanism and connect the acupuncture device body 1 to the mains via a wire; S2: attaching the acupuncture head 3 to the part that needs acupuncture; S3: After acupuncture is completed, disconnect the wire from the mains, remove the old acupuncture head 3 and install a new acupuncture head 3 through the connecting mechanism; S4: After use, the protection mechanism is restored to protect the connector 2 and the acupuncture head 3.

[0028] Working principle: When the acupuncture head 3 is to be removed for replacement, first rotate the push ring 52 to make the push ring 52 move inside the movable groove 51, push the top block 49 to move upward so that the top block 49 pulls the third spring 50 to produce elastic deformation, and at the same time make the top end of the top block 49 push the inclined surface of the connecting block 44, push the connecting block 44 to move inside the storage cavity 45 to release the state of being engaged with the connecting groove 43. When the push ring 52 is rotated upward to the limit, the top block 49 completely pushes the connecting block 44 out of the connecting groove 43. At this time, the connection between the acupuncture head 3 and the connecting head 2 is released. The tension of the third spring 50 keeps the top block 49 at the bottom of the connecting groove 43 without being affected by external force, avoiding the engagement between the connecting block 44 and the connecting groove 43. When the acupuncture head 3 is to be installed, the positioning block 41 is first aligned with the positioning groove 42, and then the acupuncture head 3 is pushed toward the connecting head 2, so that the positioning block 41 is inserted into the interior of the positioning groove 42. When the positioning block 41 is inserted into the interior of the positioning groove 42, the positioning block 41 squeezes the inclined surface on the connecting block 44, so that the connecting block 44 moves toward the interior of the storage cavity 45 under the action of the squeezing force and squeezes the second spring 46, so that the second spring 46 is elastically deformed. When the positioning block 41 is completely inserted into the interior of the positioning groove 42, the squeezing force of the positioning block 41 on the connecting block 44 disappears. At this time, the connecting block 44 automatically returns to its original position under the action of the restoring force of the second spring 46, and engages with the connecting groove 43, thereby fixing the acupuncture head 3.

[0029] When the protective cover 21 is to be removed and the acupuncture device body 1 is used, the baffle 30 is first pushed to drive the first sliding block 31 fixedly connected to the baffle 30 to move synchronously, so that the first sliding block 31 squeezes the rubber block 33 glued to the inner wall of the first sliding groove 32, so that the block 33 is elastically deformed, and then the block 33 is released from the state of being engaged with the first sliding block 31, and the fixation of the baffle 30 and the first sliding block 31 is released. At this time, the baffle 30 drives the first sliding block 31 in the first sliding groove 32. When the first sliding block 31 slides to the limit in the first sliding groove 32, the first sliding block 31 engages with the block 33 on the other side of the inner wall of the first sliding groove 32, and the position is fixed. At this time, the baffle 30 releases the blocking of the pressing block 27. At this time, the pressing block 27 is pressed toward the acupuncture device body 1, so that the pressing block 27 drives the fixedly connected fixed block 24 to move synchronously, so that the fixed block 24 is released from the state of being engaged with the fixed groove 23. At this time, the protective cover 21 automatically falls down under the action of gravity to release the connection. In order to protect the connector 2 and the acupuncture head 3, when the protective cover 21 is to be installed after the use of the acupuncture device body 1, the protective cover 21 is firstly sleeved on the outside of the connector 2 and the acupuncture head 3, and then the protective cover 21 is pushed upward, so that the inner wall of the protective cover 21 squeezes the inclined surface provided on the fixing block 24, so that the fixing block 24 moves toward the inside of the active cavity 25 under the action of the squeezing force, and squeezes the first spring 26, so that the first spring 26 produces elastic deformation under the action of the squeezing force, when the protective cover 21 When the top end of the protective sleeve 21 abuts against the retaining ring 22, the inner wall of the protective sleeve 21 no longer squeezes the fixing block 24. At this time, the fixing block 24 returns to its original position under the action of the restoring force of the first spring 26 and engages with the fixing groove 23, thereby fixing the protective sleeve 21. Then, the baffle plate 30 is pushed to return to its original position so that the baffle plate 30 blocks the pressing block 27 to prevent the pressing block 27 from driving the fixing block 24 to release the engagement with the fixing groove 23 due to an accidental collision, causing the protective sleeve 21 to fall off. At this point, the installation of the protective sleeve 21 is completed.
