Description

Technical Field

[0001] The invention relates to the technical field of tremella processing, and in particular to a laser massage therapeutic instrument. Background Art

[0002] Lasers have great uses in the fields of medicine, display, military, processing and scientific research. With the research of semiconductor lasers in medicine, scientists have found that lasers of specific wavelengths can stimulate a process called photobiomodulation (PBM), in which photons enter tissues and interact with the pigment C complex in mitochondria, which can increase the activity of its oxidases, enhance mitochondrial function, provide oxygen consumption, promote the generation of ATP, and ultimately rebuild the energy balance and signal transmission of mitochondria. PBM can promote metabolism and relieve pain and inflammation.

[0003] Laser therapy can accelerate blood circulation and improve physiological functions by irradiating human tissue with laser. In order to increase the therapeutic effect and user experience of laser irradiation, massaging the human body during laser treatment can significantly accelerate blood circulation. Massage can also relax the user's body and mind, which is conducive to improving the treatment effect and user experience.

[0004] For example, the patent announcement number CN219423271U discloses a "handheld laser massager" that uses a massage ball to contact the human body and press the human body. At the same time, the massage ball can roll by pushing the main body of the massager shell to massage the contact parts of the human body. During the massage, the laser emitted by the laser is shaped by the optical lens and the massage ball to obtain a uniform light spot, thereby improving the effect of laser treatment. It plays the role of laser therapy and massage at the same time, improving the efficacy and user experience.

[0005] The purpose of this scheme is to provide a new laser massage therapeutic device with laser physiotherapy and massage at the same time. Summary of the invention

[0035] 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.

[0036] Embodiment 1:

[0037] A laser massage therapy device, such as Figure 1-2 As shown:

[0038] It includes a housing 1, a battery 2, a semiconductor laser 3, an optical fiber 4, a heat sink 5, a thermoelectric cooling sheet 6, a temperature sensor 7, a fan 8, a control board 9, a switch 10, a motor 11, a transmission device 12, a massage head 13 and a charging port 14;

[0039] The housing 1 is in the shape of a gun, a battery 2, a control board 9 and a motor 11 are installed inside the handheld end of the housing 1, a charging port 14 is a USB charging port arranged on the bottom wall of the handheld end of the housing 1, and a switch 10 is arranged on the bottom wall of the handheld end of the housing 1; a semiconductor laser 3, an optical fiber 4, a heat sink 5, a thermoelectric cooling sheet 6, a temperature sensor 7, a fan 8 and a transmission device 12 are installed inside the barrel end of the housing 1, and a massage head 13 is linearly slidably connected to the end of the barrel end of the housing 1.

[0040] The transmission device 12 includes an eccentric wheel 15, a connecting rod 16 and a piston head 17. The eccentric wheel 15 is installed at the output end of the motor 11. The two ends of the connecting rod 16 are respectively hinged to the eccentric wheel 15 and the piston head 17. The piston head 17 is linearly slidably connected inside the barrel end of the shell 1.

[0041] Thermoelectric cooling sheet 6 is fixed to one end of heat sink 5, and fan 8 is fixed to the other end of heat sink 5; semiconductor laser 3 is fixed to thermoelectric cooling sheet 6; temperature sensor 7 is fixed to semiconductor laser 3. Temperature sensor 7 can be NTC or PT100 or thermocouple, etc.; thermoelectric cooling sheet 6 can transfer heat generated by semiconductor laser 3 to heat sink 5, and fan 8 performs air cooling on heat sink 5.

[0042] The control board 9 controls the rotation of the motor 11 and the output of the semiconductor laser 3 by checking whether the switch 10 is closed or not, and controls the operation of the thermoelectric cooling sheet 6 and the fan 8 through the temperature feedback from the temperature sensor 7 .

[0043] The motor 11 drives the eccentric wheel 15 to rotate, and the rotation of the eccentric wheel 15 drives the piston head 17 to move back and forth through the connecting rod 16, thereby driving the massage head 13 to perform tapping massage on the user. The massage head 13 has a certain light transmittance and a certain light beam convergence effect, such as resin, glass, etc. The massage head 13 emits and outputs the laser at a certain emission angle; the massage head 13 can not only vibrate and massage at high speed, but also transmit laser to achieve the purpose of massaging and irradiating at the same time.

[0044] The light of the semiconductor laser 3 is output through the optical fiber 4, and the other end of the optical fiber 4 away from the semiconductor laser 3 is fixed to the connecting rod 16 or the piston head 17 in the transmission device 12 through the flange head 18;

[0045] like Figure 2 As shown, when the optical fiber 4 is fixed on the piston head 17, the optical fiber 4 vibrates with the linear reciprocating vibration of the piston head 17, thereby achieving the effect of light spot homogenization and outputting a straight line segment of light. When the optical fiber 4 is fixed on the connecting rod 16, the optical fiber 4 performs reciprocating swinging motion with the connecting rod 16 and outputs a fan-shaped light beam.

[0046] The massage head 13 is coated with a 400nm-1100nm anti-reflection film; the massage head 13 can be a hemisphere plus a cylinder, or a spherical shape; the wavelength of the semiconductor laser 3 is 980nm and 650nm, wherein the 650nm laser plays an indicating role, and the 980nm laser is a therapeutic laser;

[0047] The control board 9 is the control center of the therapeutic apparatus, which collects the temperature of the temperature sensor 7 and controls the temperature of the semiconductor laser 3; detects the different gears of the switch 10, and controls the switch of the semiconductor laser 3 and the rotation of the motor 11; the charging port 14 is for charging the battery 2.

[0048] Embodiment 2: includes all the contents of Embodiment 1, except that Figure 3-6 As shown:

[0049] A plurality of groups of slide grooves 21 are evenly distributed and extend inwardly in a straight line on the surface of the massage head 13. The base 24 is adapted to the slide groove 21 so that the base 24 can slide in a straight line in the slide groove 21. The two ends of the return spring 23 are respectively connected to the bottom wall of the base 24 and the inner bottom wall of the slide groove 21. The massage rod 22 is rotatably connected to the top wall of the base 24. A limit ball 25 is provided on the inner side wall of the slide groove 21. A spiral guide groove 222 is provided on the outer side wall of the massage rod 22 around its rotation axis. The limit ball 25 is relatively located in the adapted spiral guide groove 222.

[0050] The setting of the spiral guide groove 222 satisfies the following conditions: when an axial force is applied to the massage stick 22, the linear motion is converted into a rotary motion through the cooperation of the limiting ball 25 and the spiral guide groove 222. Under the cooperation of the limiting ball 25 and the spiral guide groove 222, the rotation angle of the massage stick 22 relative to the base 24 is less than 180°.

[0051] The massage stick 22 is made of a non-translucent material, and a light channel 221 is provided on the massage stick 22 parallel to its rotation axis, and the optical fiber 4 is fixed on the base 24 in a one-to-one correspondence. Figure 3 As shown, the hemispherical end of the massage stick 22 is located outside the massage head 13. At this time, the laser emitted from the optical fiber 4 is staggered with the optical channel 221, thereby shielding the laser.

[0052] Since each person's usage technique is different, some areas of the massage head 13 are not involved in the massage. Through the above design, the areas of the massage head 13 that are not involved in the massage will not emit laser light, thereby avoiding light pollution to the surroundings and irradiating the eyes of people around.

[0053] During the massage process, part of the massage stick 22 of the massage head 13 contacts the user, and a reverse force is applied to this part of the massage stick 22, thereby pushing the massage stick 22 into the slide groove 21. During this process, the massage stick 22 is extended into the slide groove 21 and rotates at the same time through the cooperation of the limiting ball 25 and the spiral guide groove 222, and pushes the base 24 to move inward and compresses the reset spring 23 to generate a reverse elastic force; when the limiting ball 25 moves relatively to the lower end limit position of the spiral guide groove 222, at this time, the optical channel 221 of the massage stick 22 just rotates to align with the free end of the optical fiber 4, so that the optical fiber 4 can emit laser through the optical channel 221 for physical therapy.

[0054] Under normal conditions, the base 24 is pushed outward to be reset under the reverse elastic force of the reset spring 23. During this process, the massage stick 22 is pushed to move in the reverse direction and rotate to be reset.

[0055] Embodiment 3: includes all the contents of Embodiment 2, except that, Figure 3-7 As shown:

[0056] The base 24 includes an upper seat 241 and a lower seat 242, and the upper seat 241 and the lower seat 242 are connected by evenly arranged springs 243, and the springs 243 are in a V-shaped structure. The elastic force of the springs 243 is greater than the elastic force of the reset spring 23. Under normal circumstances, the corner of the spring 243 abuts against the inner wall of the slide groove 21, and the inner wall of the slide groove 21 is protruded to provide a limiting block 26, and the inner wall of the slide groove 21 is concave to provide a limiting groove 27 around a circle, and the limiting groove 27 is relatively located between the limiting block 26 and the massage rod 22.

[0057] When the massage rod 22 extends inward into the slide groove 21, the base 24 follows the inward movement until the bottom wall of the lower seat 242 in the base 24 abuts against the limit block 26. At this time, the spring piece 243 is just in the position of the limit groove 27. Then the massage rod 22 continues to extend inward, and in this process, the upper seat 241 is pushed to continue to extend close to the lower seat 242. The upper seat 241 approaches the lower seat 242 and compresses the elastic sheet 234. The elastic sheet 234 is elastically deformed so that its corner is inserted into the limit groove 27. At this time, the optical channel 221 of the massage rod 22 is aligned with the free end of the optical fiber 4. The cross-section of the limit groove 27 can be triangular, square or semicircular.

[0058] Due to the reciprocating motion of the massage head 13, there is a situation where the massage head 13 is temporarily separated from the user, causing the optical channel 221 of the massage stick 22 to be temporarily offset from the free end of the optical fiber 4; through the above design, since the corner of the elastic sheet 234 is inserted into the limit groove 27, it takes a certain amount of time (several seconds) for the corner of the elastic sheet 234 to break away from the limit groove 27. This time can be used to compensate for the time it takes for the massage head 13 to reciprocate one round trip, so that during the reciprocating tapping of the massage head 13, the light emitted by the optical fiber 4 is kept irradiating the user, thereby improving the effect of laser therapy.

[0059] The above-mentioned embodiments only express the specific implementation of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
