Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a carbon light therapy machine. Background Art

[0002] The carbon light therapy machine uses the spectrum emitted by the burning of two carbon rods as a light source, and uses light irradiation and heat to directly act on human skin and lesions to achieve rehabilitation treatment effects. It combines the theory of "Traditional Chinese Medicine" and is a new generation of medical equipment that integrates mechanics, electricity, light, and heat.

[0003] Currently, the carbon light therapy machines on the market are basically divided into carbon rod swing type and carbon rod linear motion type. Among them, the swing type is mostly manually adjusted, such as CN208582872U discloses a carbon light therapy device graphite rod adjustment mechanism, which is inconvenient to adjust and has certain risks. The linear motion type is divided into two types: linear opposite type and angle type, which are basically electric: for example, CN209612018U discloses a miniature portable carbon light therapy device, which drives the screw to rotate by rotating the rotary sleeve, thereby realizing the forward conveyance of the carbon rod in a straight line; for example, CN209662459U discloses a carbon light therapy device, which ensures the angle between the two rods by rotation; for example, CN209679323 discloses an angle automatic rod feeding and fixed-point combustion device for a carbon light therapy device, which relies on a clamp to realize the front and rear linear conveyance of the carbon rod; for example, CN209714007 discloses a mechanism for automatically adjusting the angle of two carbon rods of a carbon light therapy device, and the carbon rod rotates with the transmission shaft to keep the angle unchanged; for example, CN210057156 discloses a dovetail clamp type carbon rod fixing automatic feeding device for a carbon light therapy device, and the carbon rod rotates with the clamp to keep the angle unchanged; therefore, the carbon rods themselves do not rotate in the linear motion type.

[0004] As can be seen from the above, in the existing swinging structure, the position of the burning point changes due to the change of the swing angle during the combustion process, resulting in the need to continuously adjust the irradiation distance to the human body surface, otherwise it will affect the treatment effect; in the existing linear motion structure, since the carbon rod can only move linearly back and forth, the part where the two carbon rods are opposite to each other is fully burned during combustion, while the other parts cannot be completely burned, resulting in low combustion efficiency, and therefore there are problems of low and unstable light intensity. Summary of the invention

[0005] The problem to be solved by the present invention is to provide a light head for a carbon light therapy machine, wherein the carbon rod can advance in a spiral manner, ensuring that all parts on the outer circle of the carbon rod can be fully and evenly burned, while improving the combustion efficiency, ensuring the intensity and stability of the light, and improving the treatment effect; at the same time, the position of the burning point is fixed, so as long as the position of the light head is determined at the beginning, the light head does not need to be adjusted during the entire treatment process, and the intensity and stability of the light can be guaranteed, thereby ensuring the treatment effect; in addition, the light emitted from the burning points of the two carbon rods is close to parallel light, and within the illumination range, the light intensity at the center and the edge is uniform, making people feel comfortable with heat and producing the therapeutic effect of moxibustion.

[0026] Example 1

[0027] from Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 It can be seen that the light head of the carbon light therapy machine includes an external shell and a movement device arranged inside the shell; the movement device includes a reflector 1, an insulating plate 2, a transmission system, and two sets of carbon rod feeding mechanisms; the reflector 1 is located in the left section of the shell, and the insulating plate 2 is located on the right side of the reflector 1. The transmission system and the two sets of carbon rod feeding mechanisms are connected to the right end of the insulating plate 2. The two sets of carbon rod feeding mechanisms are arranged above the transmission system and are symmetrically arranged front to back; the transmission system is arranged at the lower part of the right end of the insulating plate, including a motor 12 and an output gear 13. The left end of the motor 12 is fixedly connected to the insulating plate 2, and its output shaft is connected to the output gear 13; each set of carbon rod feeding mechanisms includes a side rod 3, a fixing block 4 , swing block 7, transmission shaft 9, gear 10, transmission gear 11; the side rod 3 passes through the center holes of the reflector 1 and the insulating plate 2, and its center line is parallel to the center line of the reflector 1; the fixed block 4 is connected to the top of the side rod 3; the swing block 7 is located on the right side of the fixed block 4 and the side rod 3; the transmission shaft 9 is arranged in parallel just below the side rod 3, passes through the center holes of the reflector 1 and the insulating plate 2, and is connected to the swing block 7; the gear 10 and the transmission gear 11 are respectively arranged on the left and right outer circles of the transmission shaft 9; the transmission gear 11 of a set of carbon rod feeding mechanism located just above the transmission system is meshed with the output gear 13, and is also meshed with the transmission gear 11 of another set of carbon rod feeding mechanism.

[0028] When using the light head, first insert the carbon rod 19 into the inclined hole of the left section of the side rod 3, and the gear 10 on the transmission shaft 9 contacts the carbon rod 19; then the motor 12 works, and the output gear 13 on the output shaft transmits power to the two sets of carbon rod feeding systems to make the two rotate synchronously, that is, the transmission gear 11 drives the transmission shaft 3 to rotate, and the gear 10 rotates to make the carbon rod 19 advance in a spiral manner, ensuring that the distance between the heads of the two carbon rods remains unchanged; in addition, the positions of the inclined holes at the heads of the two side rods 3 are fixed, so the angles of the two carbon rods 19 installed in the two side rods remain unchanged; because the sphere of the reflector 1 is a concave mirror, the positions of the heads of the two carbon rods 19 are exactly at the f point (focus) of the concave mirror, so the light emitted by the carbon rod 19 when burning becomes parallel lines after being reflected by the concave mirror and emitted from the grid of the protective cover, so during treatment, the irradiation distance of the light to the human body surface is fixed, ensuring the treatment effect; at the same time, the spiral advancement of the carbon rod 19 enables all parts to be fully burned, with high combustion efficiency and high and stable light intensity.

[0030] The illumination head of the carbon light therapy machine: the left section of the side rod 3 is located in the reflector 2, and the right section is located in the shell on the right side of the insulating plate 2. The left section of the side rod 3 is provided with a hole inclined to its center line, and a small square groove is processed below one section of the hole, and the small square groove is connected to the through hole. The right section of the side rod 3 is provided with a vertical large square groove; the swing block 7 is divided into three sections: upper, middle and lower. The upper section is processed with a transverse threaded hole, the lower section is processed with a transverse light hole, the middle section is flat and stuck in the large square groove of the right section of the side rod 3; the left section of the transmission shaft 9 is located in the reflector 1, and the right section is located in the shell on the right side of the insulating plate 2.

[0031] Example 3

[0032] The light head of the carbon light therapy machine: the fixed block 4 is fixedly connected to the top of the side rod 3 by screws, the left end of which is fixedly connected to the insulating plate 2, and the right end is provided with a blind hole, in which a spring 5 and a movable push rod 6 are provided, and the movable push rod 6 is clamped on the spring 5; the adjustable screw 8 passes through the threaded hole on the upper section of the swing block 7 and is located on the right side of the movable push rod 6.

[0033] Example 4

[0034] Light head of carbon light therapy machine: Each set of carbon rod feeding mechanism also includes a small connecting plate 14, which is arranged on the small diameter outer circle of the right section of the transmission shaft 9 and pressed tightly on the right end face of the swing block 7. The screw passes through the small connecting plate 14 to position both the transmission shaft 9 and the swing block 7. The small connecting plate 14 connects the transmission shaft 9 and the swing block 7 into a whole.

[0035] Light head of carbon light therapy machine: Each set of carbon rod feeding mechanism also includes a positioning pin 15, which passes through the right section of the side rod 3 and the middle section of the swing block 7 to connect the side rod 3 and the swing block 7; the upper section of the swing block 7 is provided with a vertical threaded hole, and the locking screw 16 is screwed into the vertical threaded hole and pressed against the outer circumferential surface of the positioning pin 15. The locking screw 16 prevents the positioning pin 15 from loosening, making the connection between the side rod 3 and the swing block 7 more reliable.

[0036] Example 5

[0037] The light head of the carbon light therapy machine: the shell includes a shell body 17 and a protective cover 18; the shell body 17 is a combination of a circular ring on the left section and an arc on the right section, the outside of the protective cover 18 is fitted into the left end of the shell body 17, and the inside of the protective cover 18 is a grid.

[0038] Light head of carbon light therapy machine: the reflector 1 includes a left sphere and a right end connecting plate 20. The reflector 1 is connected to the insulating plate 2 via the connecting plate 20. The outer circumference of the insulating plate 2 is connected to the shell body 17. The left sphere of the reflector 1 actually forms a concave mirror.

[0039] When the carbon rod 19 needs to be replaced, the protective cover 18 is opened, and the transmission shaft 9 is pressed down with a special tool to move the gear 10 downward, and the transmission shaft 9 moves downward, driving the swing member 7 to rotate, and the adjustable screw 8 is pressed on the movable push rod 6, and the spring 5 is compressed. At this time, the carbon rod 19 is installed in the inclined hole of the left section of the side rod 3; when the carbon rod 19 is installed, the special tool is taken out to remove the downward pressure of the transmission shaft 9, and the movable push rod 6 is extended under the action of the spring 5, and the adjustable screw 8 drives the swing member 7 to rotate in the opposite direction, and the transmission shaft 9 moves upward, and the gear 10 is just pressed on the carbon rod 19.

[0040] When using the light head, first insert the carbon rod 19 into the inclined hole of the left section of the side rod 3, and the gear 10 on the transmission shaft 9 contacts the carbon rod 19; then the motor 12 works, and transmits power to the two sets of carbon rod feeding systems through the output gear 13 on the output shaft to make the two rotate synchronously, that is, the transmission gear 11 drives the transmission shaft 3 to rotate, and the gear 10 rotates to make the carbon rod 19 advance in a spiral manner, ensuring that the distance between the heads of the two carbon rods remains unchanged; since the positions of the inclined holes at the heads of the two side rods 3 are fixed, the angles of the two carbon rods 19 installed in the two side rods remain unchanged. Because the reflector 1 sphere is a concave mirror, the positions of the heads of the two carbon rods 19 are exactly at the f point (focus) of the concave mirror, so the light emitted by the carbon rod 19 when burning becomes parallel lines after being reflected by the concave reflector, and is emitted from the grid of the protective cover to treat the relevant parts of the human body.

[0041] Example 6

[0042] from Figure 1 , Figure 2 , Figure 3, Figure 4 , Figure 7 , Figure 8 , Fig. 9 It can be seen that the tilting device of the carbon light therapy machine includes a support plate 21, a column 22, two front and rear bearing seats 23, a pressure plate 24, a pin 25, and two springs 26; a groove is processed on the front and rear symmetrical surfaces of the support plate 21, and a bearing seat 23 is arranged in each groove, and screws connect the support plate 21 and the bearing seat 23 from bottom to top; the column 22 passes through the center hole of the support plate 21; the pin 25 passes through the front bearing seat, the column, and the rear bearing seat, and cooperates with the inner holes of the three; the lower parts of the two springs 26 are respectively arranged in the open grooves before and after the pin, and the upper parts are located in the grooves of the front and rear bearing seats; the pressure plate 24 is pressed tightly on the front and rear bearing seats and the column, and is connected to the three by screws.

[0043] Among them, the lower part of the front and rear bearing seats 23 is provided with an opening along the front-to-rear direction, the upper part of the opening is communicated with the inner hole of the upper part, and the screw passes through the left and right parts of the opening.

[0044] The tilting device is set at the bottom of the light head. When the angle of the light head needs to be adjusted, you only need to apply force to the light head, and the light head can rotate to a suitable position along with the pin shaft. No matter where the person is, the light source can be guaranteed to shine on the human body. Among them, an open sliding bearing seat is set in the tilting device. By adjusting the holding force of the shaft with screws, the radial damping and support shaft functions are achieved. In addition, the spring support ensures the stability of the movement, so it feels light and is reliable to use.

[0045] Example 7

[0046] from Figure 1 , Figure 2 It can be seen that the carbon light therapy machine of the present invention comprises a light irradiation head, a tilting device, and an electrical component box; the light irradiation head and the electrical component box are respectively arranged on the upper side and the lower side of the tilting device.

[0047] Among them, the shell body 17 of the light irradiation head is provided with a streamlined armrest 27. The armrest 27 is used to facilitate the adjustment of the angle of the light irradiation head, and the parallel ears at both ends thereof can also be used as a reference for the tilting angle.

[0048] The carbon light therapy machine of the present invention is small in size, can be conveniently carried, and can be used alone. It can also be used in combination with other devices such as a lift.

[0049] The advantages of the present invention are as follows: First, since the positions of the inclined holes at the heads of the two side rods in the illumination head are fixed, the angles of the two carbon rods installed in the two side rods remain unchanged at a fixed angle. In addition, the carbon rods will be transported forward, so the position of the combustion point (the head of the carbon rod) is fixed, that is, the position of the light source remains unchanged. Therefore, as long as the position of the illumination head is determined at the beginning, there is no need to adjust the illumination head during the entire treatment process, and the illumination intensity and stability can be guaranteed, thereby ensuring the treatment effect; Second, since there is a certain angle between the carbon rod and the transmission shaft, that is, the carbon rod and the gear, when the gear rotates, the carbon rod realizes the forward and backward rod movement in the form of a spiral motion. The spiral motion ensures that all parts on the outer circle of the carbon rod can be fully and evenly burned, while improving the combustion efficiency. The intensity and stability of light are guaranteed, and the therapeutic effect is improved; third, the angles of the two carbon rods remain unchanged and the carbon rods move forward in a spiral manner, so that the burning point of the head of the carbon rod is always at the parabola focus position of the reflector, that is, point f, so the emitted light is close to the parallel light, thereby enhancing the light intensity, and the light intensity is stable, and within the illumination range, the light intensity at the center and the edge is uniform, making people feel comfortable and producing the therapeutic effect of moxibustion; fourth, the tilting device is easy to adjust and the movement is smooth. The height of the illumination head is adjustable, and the illumination head can be tilted and pitched, which is convenient for accurate positioning of the illumination position; fifth, after the carbon rod is burned, the remaining rod automatically falls into the illumination head. You only need to open the protective cover, take out the remaining short rod, and insert a new carbon rod. It is easy to replace the carbon rod.

[0050] Therefore, when the carbon light therapy machine of the present invention is used for treatment, the light head can be conveniently adjusted to the desired position by the tilting device after the carbon rod is ignited. During the entire treatment time, the machine does not need to be adjusted any more.
