[0042] In order to help those skilled in the art better understand the present invention, 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 embodiments described 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 making creative efforts should fall within the scope of protection of the present invention.

[0043] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0044] Figure 1 This is a schematic diagram of a laser therapy device provided by an embodiment of the present invention. The laser therapy device provided by this embodiment can be used for applications such as using laser to care for the scalp, but is not limited thereto. It can also be used to treat the skin of other parts of the user's body. Figure 1 As shown, the laser therapy device 100 includes: a support part 110, which is used to fit at least part of the skin, such as the scalp 200; a laser emitting part 120, which is arranged on the inner surface of the support part 110 facing the skin, such as the scalp 200, and the laser emitting part 120 includes at least one vortex laser unit 121; the vortex laser unit 121 is used to emit vortex laser.

[0045] In this embodiment, the laser therapy device 100 includes a support portion 110. Optionally, the support portion 110 may be flexible, which improves wearing comfort and facilitates adaptation to the needs of different users. In other embodiments, the support portion may be rigid, which is less susceptible to deformation. Those skilled in the art may design the support portion to be flexible or rigid, depending on their needs.

[0046] The optional support part can be in the shape of a headband type support part; or in the shape of a helmet type support part. The main purpose of the laser therapy device 100 is to use laser to treat the scalp 200 of the user's head. Therefore, the laser therapy device 100 needs to be worn on the user's head. Based on this, the shape of the support part 110 can be designed as follows: Figure 1The semicircular headband design shown has a certain width for easy wear on the user's head. In other embodiments, the support portion can be designed in a helmet-like design, which covers a larger scalp area than the headband design. Those skilled in the art can design the shape of the support portion as needed.

[0047] It can be understood that by deforming the shape of the support portion 110 based on the structure of the laser therapy device 100, the resulting laser therapy device can be used in other therapy application scenarios that require laser care.

[0048] For example, if laser therapy is required for the back of the human body, the shape of the support portion 110 in the laser therapy device 100 can be designed to be a flat plate, so that it can be transformed into a laser therapy device for caring for the back of the human body. Figure 2 This is a schematic diagram of a laser instrument provided by an embodiment of the present utility model. The laser instrument 300 provided by this embodiment can be used for applications such as using laser to care for the back of the human body. Figure 2 The laser instrument 300 shown is Figure 1 The difference is that the support part 110 of the laser instrument 300 is flat, and the laser emitting part 120 is arranged on the side surface of the support part 110 facing the back of the human body.

[0049] Figure 3 This is a schematic diagram of another laser instrument provided by an embodiment of the present invention. The laser instrument 300 provided by this embodiment can be used for applications such as using laser to care for the human face, such as removing moles, removing spots, optical acupuncture such as laser acupuncture, etc. Figure 3 In the illustrated laser instrument 300, the support portion 110 may be plate-shaped or block-shaped, and the laser emitting portion 120 may include only a single vortex laser unit 121. The vortex laser unit 121 is configured to emit a vortex laser that is projected onto the area to be treated, enabling localized, point-to-point treatments such as mole and freckle removal.

[0050] Figure 4 This is a schematic diagram of another laser instrument provided by an embodiment of the present utility model. The laser instrument 300 provided in this embodiment can be applied to applications such as using laser to care for parts of the human body. Figure 4 In the illustrated laser device 300, the support portion 110 may be a disc-shaped plate, and the laser emitting portion 120 may include multiple vortex laser units 121 for emitting vortex laser light. The support portion 110 can rotate at multiple angles, thereby driving the multiple vortex laser units 121 thereon to rotate, enabling multi-angle treatment.

[0051] It is understood that the shape of the laser therapy device can be adjusted according to the application scenario or usage needs to meet the usage needs of different users and different scenarios.

[0052] The following text only focuses on the laser therapy device for the head and describes its structure and working conditions.

[0053] Those skilled in the art can reasonably design the shape of the support portion as needed to transform the laser therapy device into a variety of different laser instruments suitable for different application scenarios. It is understood that if the laser instrument is used in different scenarios, the optical parameters of the vortex laser emitted by the vortex laser unit will also be adjusted to suit different usage scenarios.

[0054] The laser therapy device 100 includes a laser emitting unit 120. The laser emitting unit 120 is configured on the inner surface of the support unit 110 facing the scalp 200 of the user's head. Correspondingly, the side of the support unit 110 facing away from the scalp 200 of the user's head is the outer surface of the support unit 110. It can be understood that the backlight side of the laser emitting unit 120 is in contact with the inner surface of the support unit 110, and the light-emitting side of the laser emitting unit 120 directly emits vortex laser light to the target object, such as the scalp 200 of the user's head. Figure 1 As shown, the light emission direction of the vortex laser emitted by the laser emitting unit 120 is shown by the arrow.

[0055] The laser emitting unit 120 includes multiple vortex laser units 121, which are used to emit vortex lasers. Specifically, the vortex laser units 121 include laser light-emitting devices that can generate laser light. They also include vortex phase devices that can vortex the laser light. The vortex phase devices are located on the light-emitting side of the laser light-emitting devices. The laser light-emitting devices in the vortex laser units 121 emit laser light, and then the vortex phase devices in the vortex laser units 121 vortex the laser light. The vortex laser units 121 can then emit vortex laser light toward a target object.

[0056] Vortex light can be used in a variety of optical devices, and is currently widely used in optical microscopes, optical communications equipment, optical manipulation equipment, optical processing equipment, and optical sensing equipment. Research has found that vortex lasers have significant hair growth effects. Therefore, the present invention incorporates vortex lasers into physical therapy equipment, which is beneficial for scalp care and hair growth.

[0057] Figure 5 This is a schematic diagram of a laser emitting unit provided by an embodiment of the present utility model. Figure 5As shown, the multiple vortex laser units 121 in the laser emitting unit 120 can be arranged in an array to provide a uniform distribution of vortex laser light to the user's scalp. However, this is not limiting, and those skilled in the art can reasonably design the arrangement of the multiple vortex laser units in the laser emitting unit according to their needs. Figure 6 This is a schematic diagram of another laser emitting unit provided by an embodiment of the present utility model. Figure 6 As shown, the laser emitting portion 120 includes multiple rows of vortex laser units, one row of vortex laser units includes multiple vortex laser units 121 , and the vortex laser units 121 in two adjacent rows of vortex laser units are arranged in a staggered manner.

[0058] In addition, the optical parameters of the vortex laser emitted by the vortex laser unit 121 are adjustable, and the operator can adjust the optical parameters of the vortex laser emitted by the vortex laser unit 121 according to user needs. For example, the optical power of the vortex laser unit 121 can be adjusted based on the distance between the light-emitting surface of the vortex laser unit 121 and the scalp.

[0059] It should be noted that Figure 1 The support portion 110 is shown as not in contact with the scalp 200. This is merely to illustrate the relative position of the laser therapy device 100 and the user's head, and does not represent the actual wearing situation. In actual use, when the laser therapy device 100 is worn on the user's head, the support portion 110 is in contact with at least a portion of the scalp 200.

[0060] The laser therapy device provided by this utility model has a support portion that fits at least partially on the scalp. A laser emitting portion is disposed on the inner surface of the support portion, facing the scalp, and includes multiple vortex laser units. The vortex laser units emit vortex laser light that is projected onto the user's scalp, providing laser treatment for the user's scalp. In this utility model, the laser therapy device emits vortex laser light, which helps maintain the user's scalp and promote scalp hair growth. The laser therapy device has a simple structure and is relatively low in cost.

[0061] The above is the main solution of the present invention. The structure of the laser therapy device of the present invention will be described below through multiple embodiments. It should be understood that the laser therapy device shown in the figure only schematically illustrates the part of the device structure related to the technical solution. The actual structure of the laser therapy device is not the simple structure shown in the figure, but is equipped with a complete circuit and other necessary components, etc., which will not be described in detail here.

[0062] Figure 7 This is a schematic diagram of another laser emitting unit provided by the embodiment of the present utility model, combined with Figure 1 and Figure 7As shown, the optional laser emitting part 120 includes: a laser array 130 and a first cover plate 140, the laser array 130 is located between the support part 110 and the first cover plate 140; the laser array 130 includes a plurality of lasers 131, the first cover plate 140 has a plurality of light-transmitting areas 141, one laser 131 corresponds to one light-transmitting area 141, and the light-transmitting area 141 has a spiral step structure 142; the vortex laser unit 121 includes a light-transmitting area 141 and a corresponding laser 131.

[0063] In this embodiment, Figure 7 The laser emitting portion 120 is shown as a flat plate, which is only for the purpose of illustrating the stacked structure of the laser emitting portion 120 and does not refer to the actual shape. In practice, the shape of the laser emitting portion 120 changes with the shape of the support portion 110. Figure 1 As shown, the laser emitting portion 120 is semicircular in shape to match the shape of the headband-type support portion 110. In the following embodiments, the laminated structure of the laser emitting portion 120 is described by taking the flat-plate-shaped laser emitting portion 120 as an example.

[0064] The laser emitting portion 120 includes a laser array 130, which is attached to the inner surface of the support portion 110, with the light-emitting side of the laser array 130 facing the first cover plate 140. The laser array 130 includes multiple lasers 131, which can be finished micro laser heads. The type of laser 131 is not specifically limited, and all lasers suitable for physical therapy devices fall within the scope of protection of the present invention.

[0065] The laser emitting unit 120 includes a first cover plate 140 disposed on the light-emitting side of the laser array 130. The first cover plate 140 can be a light-transmitting cover plate, in which case the area of ​​the first cover plate 140 corresponding to the laser 131 is defined as a light-transmitting area 141; alternatively, the first cover plate 140 can have multiple light-transmitting areas 141, with the area outside the light-transmitting areas 141 being a non-light-transmitting area. One laser 131 corresponds to one light-transmitting area 141, and along the direction from the laser 131 to the corresponding light-transmitting area 141, the projection of the light-transmitting area 141 can overlap the projection of the corresponding laser 131, or the projection of the light-transmitting area 141 can overlap the projection of the corresponding laser 131.

[0066] The light-transmitting region 141 has a spiral staircase structure 142. Accordingly, the vortex laser unit 121 includes the light-transmitting region 141 and a corresponding laser 131. Specifically, the vortex laser unit 121 includes at least a laser light-emitting device and a vortex phase device. The laser light-emitting device can generate laser light, and the vortex phase device can vortex the laser light. Specifically, the optional laser light-emitting device includes the laser 131, and the vortex phase device includes a light-transmitting region 141 having a spiral staircase structure 142. The laser 131 generates laser light, and the laser light is vortexed after passing through the spiral staircase structure 142 of the light-transmitting region 141. The vortex laser unit 121 can then emit vortex laser light.

[0067] Figure 8 This is a working diagram of a vortex laser unit provided by an embodiment of the present invention. Figure 8 As shown, the vortex laser unit 121 includes a laser 131 and a spiral staircase structure 142. The spiral staircase structure 142 can be gradually thickened along the circumferential direction. The laser 131 generates laser light, and the laser light is vortexed after passing through the spiral staircase structure 142. Then, the vortex laser unit 121 can emit vortex laser light. It can be understood that Figure 8 The spiral staircase structure 142 is only a simple schematic diagram. In practice, there are many shapes of spiral staircase structures, not limited to Figure 8 As shown, those skilled in the art can reasonably select a spiral staircase structure suitable for the vortex laser unit according to product requirements.

[0068] It is understood that the arrangement of the plurality of light-transmitting areas 141 in the first cover plate 140 should be consistent with the arrangement of the plurality of lasers 131 in the laser array 130, so that one laser 131 can be arranged corresponding to one light-transmitting area 141. Figure 7 As shown, the vortex laser emitted by the vortex laser unit 121 has a light-emitting direction as shown by an arrow.

[0069] In this embodiment, the spiral staircase structure 142 of the light-transmitting area 141 is optionally an integrally formed structure with the first cover plate 140. Specifically, a first cover plate 140 having a plurality of light-transmitting areas 141 is provided, and the spiral staircase structure 142 is directly processed on the surface of the light-transmitting area 141 on the side facing away from the laser 131. The laser emitted by the laser 131 can be vortexed after passing through the spiral staircase structure 142 of the light-transmitting area 141. The spiral staircase structure 142 can be optionally processed on the surface of the light-transmitting area 141 on the side facing away from the laser 131 using an embossing process. However, the processing technology of the spiral staircase structure 142 is not limited to the embossing process, and those skilled in the art can also select other suitable processes to directly process the spiral staircase structure 142 in the light-transmitting area.

[0070] The laser emitting unit 120 provided in this embodiment includes a laser array 130 and a first cover plate 140. Its structure is simple, and damaged parts can be replaced without affecting other components. For example, if a laser 131 is damaged, it can be directly replaced. The simple and low-cost structure of the first cover plate 140 reduces the processing cost of the laser emitting unit 120, facilitating large-scale production and achieving a high yield.

[0071] It should be noted that, for any embodiment of the present invention, the spiral staircase structure formed therein can be stepped or continuous, and the base plate of the spiral staircase structure can be made of fused quartz or a polymer material, etc. The desired spiral staircase structure can be formed by processing according to the vortex light parameters required for the actual application. In other embodiments, the spiral staircase structure can also be produced using a 3D printer or by integrally molding using optical glass or optical plastic materials. The formation methods are diverse and not specifically limited.

[0072] refer to Figure 8 As shown, the optional spiral stair structure 142 is a step-type, wherein the spiral stair structure 142 includes multiple steps 142t of different thicknesses, and the thicknesses of the multiple steps 142t arranged in sequence along the circumferential direction gradually increase, so the spiral stair structure 142 gradually becomes thicker along the circumferential direction.

[0073] Figure 9 Schematic diagram of a spiral staircase structure provided by an embodiment of the present invention. Figure 9 As shown, the spiral staircase structure 142 is continuous. The optional spiral staircase structure 142 includes a circular area 12 and an annular area 13 provided on the bottom plate 11. The diameter of the circular area 12 is smaller than the inner diameter of the annular area 13. The circular area 12 gradually becomes thicker along the circumferential direction, and the annular area 13 gradually becomes thicker along the circumferential direction. Figure 8 The difference is that Figure 9 In either the middle circular area 12 or the annular area 13, the process of gradually becoming thicker along the circumferential direction is continuous. Figure 9 As shown, the spiral step structure 142 may optionally include only a circular area 12 provided on the bottom plate 11 , and the circular area 12 gradually becomes thicker along the circumferential direction.

[0074] Figure 10 This is a schematic diagram of another laser emitting unit provided by the embodiment of the present utility model, combined with Figure 1 and Figure 10As shown, the optional laser emitting section 120 includes: a laser array 130 and a first cover plate 140. The laser array 130 is located between the support portion 110 and the first cover plate 140. The laser array 130 includes multiple lasers 131. The first cover plate 140 has multiple light-transmitting areas 141, with each laser 131 corresponding to a light-transmitting area 141. The light-transmitting areas 141 have a spiral step structure. The vortex laser unit 121 includes the light-transmitting areas 141 and the corresponding lasers 131. The light-transmitting areas 141 include light-transmitting holes 143 and spiral phase plates 142a disposed in the light-transmitting holes 143.

[0075] In this embodiment, the spiral staircase structure can be selected as a spiral phase plate 142a. The light-transmitting area 141 having the spiral staircase structure includes a light-transmitting hole 143 and a spiral phase plate 142a disposed in the light-transmitting hole 143. Figure 7 The difference is that Figure 10 The first cover plate 140 and the spiral staircase structure are composed of two parts, not Figure 7 The two shown are integrally formed.

[0076] Specifically, a first cover plate 140 is provided, and a plurality of light-transmitting holes 143 are formed in the first cover plate 140. Figure 10 The light-transmitting hole 143 shown can pass through the first cover plate 140, but is not limited thereto. In other embodiments, the depth of the light-transmitting hole can be less than the thickness of the first cover plate, that is, the light-transmitting hole may not pass through the first cover plate. In this case, the transmittance of the light-transmitting hole should meet product requirements. A spiral phase plate 142a is installed in the light-transmitting hole 143, and the laser emitted by the laser 131 can be vortexed after passing through the spiral phase plate 142a. Accordingly, the vortex laser unit 121 includes a spiral phase plate 142a and a corresponding laser 131.

[0077] The laser emitting unit 120 provided in this embodiment includes a laser array 130 and a first cover plate 140. A spiral phase plate 142a is mounted in a light-transmitting hole 143 of the first cover plate 140. This simple structure allows for the replacement of damaged parts without affecting other components. For example, if the vortex light parameters of the spiral phase plate 142a do not meet the requirements of a laser therapy device, it can be directly replaced without replacing the entire first cover plate 140, thus reducing production costs.

[0078] Figure 11 This is a schematic diagram of another laser emitting unit provided by an embodiment of the present invention, wherein the spiral staircase structure can be a spiral phase patch 142b. Figure 7 The difference is that Figure 11 The first cover plate 140 and the spiral staircase structure are composed of two parts, not Figure 7 The two shown are integrally formed.

[0079] Specifically, a first cover plate 140 having a plurality of light-transmitting areas 141 is provided, and a spiral phase patch 142b is directly attached to the surface of the light-transmitting area 141 on the side facing away from the laser 131. The spiral step structure includes the light-transmitting area 141 and the spiral phase patch 142b attached to the light-transmitting area 141. The laser emitted by the laser 131 can be vortexed after passing through the spiral phase patch 142b of the light-transmitting area 141. The spiral phase patch 142b can be optionally adhered to the first cover plate 140 through a light-transmitting adhesive layer 144. Accordingly, the vortex laser unit 121 includes a spiral phase patch 142b and a corresponding laser 131. The thickness of the spiral phase patch 142b can be a thin sheet less than or equal to 0.5 mm, which is convenient for attaching it to the laser 131.

[0080] The first cover plate 140 can be optionally a light-transmitting cover plate. Based on the change in the arrangement of the lasers 131 in the laser array 130, the spiral phase patch 142b can be flexibly attached to the first cover plate 140, and is not limited to the arrangement of the light-transmitting holes or light-transmitting areas. This can improve the flexibility of product assembly and also improve the product yield. For example, the first cover plate 140 can be mass-produced and configured in multiple laser arrays 130 of different sizes or different arrangements; for any one of the laser arrays 130, based on the arrangement of the lasers 131 in the laser array 130, the spiral phase patch 142b can be attached to the corresponding first cover plate 140. This can improve the production efficiency of the laser emitting unit and reduce costs.

[0081] Figure 12 This is a schematic diagram of another laser emitting unit provided by the embodiment of the present utility model, combined with Figure 1 and Figure 12 As shown, the optional vortex laser unit 121 includes: a laser 131 and a light-transmitting element 150 located on the light-emitting side of the laser 131; a surface of the light-transmitting element 150 facing away from the laser 131 has a spiral step structure 151.

[0082] In this embodiment, the laser emitting portion 120 includes a plurality of vortex laser units 121. The vortex laser unit 121 is an integral structure.

[0083] The vortex laser unit 121 includes a laser 131, in which the laser 131 can be a finished micro laser head. The type of laser 131 is not specifically limited, and all lasers suitable for physiotherapy devices fall within the scope of protection of the present invention. The vortex laser unit 121 also includes a light-transmitting element 150 attached to the light-emitting side of the laser 131, and the side of the light-transmitting element 150 facing away from the laser 131 has a spiral step structure 151. Specifically, the laser 131 is a laser light-emitting device for generating laser light in the vortex laser unit 121, and the light-transmitting element 150 with the spiral step structure 151 is a vortex phase device for vortexing the laser light in the vortex laser unit 121. The laser 131 generates laser light, and the laser light is vortexed after passing through the spiral step structure 151 of the light-transmitting element 150, and the vortex laser unit 121 can emit vortex laser light.

[0084] The light-transmitting element 150 and the spiral staircase structure 151 can be formed into an integral structure. Specifically, a light-transmitting element 150 such as a light-transmitting protective film, a light-transmitting sheet, or a light-transmitting plate is provided, and the spiral staircase structure 151 is directly processed on the surface of the light-transmitting element 150 facing away from the laser 131, and then the light-transmitting element 150 is attached to the light-emitting surface of the laser 131. Among them, the spiral staircase structure 151 can be directly processed on the surface of one side of the light-transmitting element 150 using an embossing process, but the processing technology of the spiral staircase structure 151 is not limited to the embossing process. Those skilled in the art can also select other suitable processes to directly process the spiral staircase structure in the light-transmitting element.

[0085] In this embodiment, the vortex laser unit 121 is an integral structure, and the laser emitting unit 120 includes multiple vortex laser units 121. This simple structure allows for replacement of damaged parts without affecting other components, reducing production costs and facilitating large-scale production with a high yield rate. Furthermore, the number of vortex laser units 121 in the laser emitting unit 120 and their arrangement can be flexibly designed based on application requirements and the size requirements of the laser emitting unit 120, thereby meeting the needs of different users and application requirements in various scenarios.

[0086] In other embodiments, the optional spiral staircase structure is a spiral phase patch. Figure 12 The difference is that in this embodiment, the light-transmitting element and the spiral staircase structure are composed of two parts, not Figure 12 Specifically, a light-transmitting element is provided, and a spiral phase patch is directly attached to the surface of the light-transmitting element on the side facing away from the laser. The spiral staircase structure includes a light-transmitting element and a spiral phase patch attached to the light-transmitting element.

[0087] Figure 13 This is a schematic diagram of another laser emitting unit provided by the embodiment of the present utility model, combined with Figure 1 and Figure 13 As shown, the optional vortex laser unit 121 includes: a laser light-emitting element 121a and a light-transmitting layer 121b; a surface of the light-transmitting layer 121b facing away from the laser light-emitting element 121a has a spiral staircase structure 121c.

[0088] In this embodiment, the laser emitting portion 120 includes a plurality of vortex laser units 121. The vortex laser unit 121 is an integral structure.

[0089] The vortex laser unit 121 is a finished device that is manufactured as a whole. Specifically, a laser light emitting element 121a is manufactured, and then a light-transmitting layer 121b is formed on the laser light emitting element 121a, and a spiral staircase structure 121c is formed on the surface of the light-transmitting layer 121b on the side facing away from the laser light emitting element 121a.

[0090] The finished laser includes a protective cover plate, which does not have a spiral staircase structure. The difference from the finished laser is that in this embodiment, the original protective cover plate can be replaced with a light-transmitting layer 121b during the manufacturing process of the laser to form the required vortex laser unit 121. Therefore, it is only necessary to add a process of setting the spiral staircase structure 121c to obtain the vortex laser unit 121 based on the current finished laser. The type of laser light-emitting element is not specifically limited, and all laser light-emitting elements suitable for physical therapy devices fall within the scope of protection of the present utility model.

[0091] The light-transmitting layer 121b and the spiral staircase structure 121c are optionally integrally formed. Specifically, the light-transmitting layer 121b is formed on the laser light-emitting element 121a, and the spiral staircase structure 121c is directly processed on the surface of the light-transmitting layer 121b facing away from the laser light-emitting element 121a. Optionally, a stamping process is used to directly process the spiral staircase structure 121c on the surface of one side of the light-transmitting layer 121b. However, the processing technology of the spiral staircase structure is not limited to the stamping process. Those skilled in the art can also choose other suitable processes to directly process the spiral staircase structure in the light-transmitting layer. The thickness of the light-transmitting layer 121b can be a thin sheet greater than 0.5 mm, which is convenient for replacing the original protective transparent cover in the laser.

[0092] In this embodiment, the vortex laser unit 121 is an integral structure, and the laser emitting unit 120 includes multiple vortex laser units 121. This simple structure allows for replacement of damaged parts without affecting other components, reducing production costs and facilitating large-scale production with a high yield rate. Furthermore, the number of vortex laser units 121 in the laser emitting unit 120 and their arrangement can be flexibly designed based on application requirements and the size requirements of the laser emitting unit 120, thereby meeting the needs of different users and application requirements in various scenarios.

[0093] In other embodiments, the optional spiral staircase structure is a spiral phase patch. Figure 13 The difference is that in this embodiment, the light-transmitting layer and the spiral staircase structure are composed of two parts, not Figure 13 Specifically, a light-transmitting layer is formed on the laser light-emitting element, and a spiral phase patch is directly attached to the surface of the light-transmitting layer facing away from the laser light-emitting element. The spiral staircase structure includes the light-transmitting layer and the spiral phase patch thereon.

[0094] The optional vortex laser unit also includes a collimator. The vortex laser unit is used to generate laser light, collimate the laser light using the collimator, and then vortex the processed laser light to emit vortex laser light. Specifically, the vortex laser unit includes a laser light-emitting device that can generate laser light, and a vortex phase device that can vortex the laser light. The vortex phase device is positioned on the light output side of the laser light-emitting device. The vortex laser unit also includes a collimator positioned between the laser light-emitting device and the vortex phase device.

[0095] If the laser light-emitting device is a non-collimated laser, or the laser emitted by the laser light-emitting device is a low-quality factor divergent laser, in this case, an optical collimator can be added between the laser light-emitting device and the vortex phase device. The collimator can then collimate the laser emitted by the laser light-emitting device, and then the vortex phase device in the vortex laser unit vortexes the laser. The vortex laser unit can then emit vortex laser light toward the target object.

[0096] Here with Figure 10 Taking the laser emitting unit shown in the figure as an example, a laser emitting unit is provided. Figure 14 This is a schematic diagram of another laser emitting unit provided by an embodiment of the present utility model. Figure 14 As shown, the collimating plate 160 is disposed between the laser array 130 and the first cover plate 140 .

[0097] Figure 15 This is a schematic diagram of another laser therapy device provided by the present invention. Figure 15 As shown, the optional laser therapy device 100 also includes: a control unit 170, connected to the laser emitting unit 120, for controlling the laser emitting unit 120 to turn on or off according to external instructions.

[0098] In this embodiment, the laser therapy device 100 further includes a control unit 170. The control unit 170 optionally includes a touch-sensitive unit, which an operator can manually control to turn the laser emitting unit 120 on or off. The control unit 170 also optionally includes a gear adjustment unit, which an operator can manually control to adjust the gear of the vortex laser parameters in the laser emitting unit 120.

[0099] Specifically, the laser emitting unit 120 includes multiple vortex laser units 121, and the first cover plate 140 has multiple light-transmitting areas 141. The laser emitting unit 120 is fixed to the inner side of the support portion 110 and is disposed between the support portion 110 and the first cover plate 140. Each vortex laser unit 121 is corresponding to each light-transmitting area 141, and the vortex laser generated by the vortex laser unit 121 is projected through the light-transmitting area 141.

[0100] In other embodiments, the optional control unit communicates wirelessly with a mobile terminal, which may be a smart phone or other device. The operator can operate on the smart phone to turn the laser emitting unit on or off, and can also adjust the gear position of the vortex laser parameters in the laser emitting unit.

[0101] refer to Figure 15 As shown, the hairband laser therapy device also includes other components, such as a closed shell, a light board, and comb teeth for combing hair, which will not be described in detail here. Figure 15 As shown, the hairband laser therapy device also includes a combing portion 180 for combing hair. The combing portion 180 includes a plurality of comb teeth 181. Each vortex laser unit 121 is corresponding to a comb tooth 181. The vortex laser generated by the vortex laser unit 121 is projected through the light-transmitting area 141 and then through the comb teeth 181 to the user's scalp.

[0102] In other embodiments, the vortex laser unit may be optionally disposed on the top of the comb teeth, and the top of the comb teeth may have a light-transmitting area or a through hole, and the vortex laser generated by the vortex laser unit may be projected onto the user's scalp through the comb teeth.

[0103] I understand. Figure 15 The laser therapy device shown includes a comb structure for combing hair. However, the laser therapy device may also not include a comb structure, for example Figure 1 As shown. Those skilled in the art can reasonably design other supporting components of the laser therapy device according to the application requirements. Based on the basic structure of the laser therapy device, those skilled in the art can modify it to meet the use requirements of different application scenarios, not limited to therapy devices.

[0104] It should be understood that the various forms of the processes shown above can be used to reorder, add, or delete steps. For example, the steps described in this utility model can be performed in parallel, sequentially, or in a different order, as long as the desired results of the technical solution of this utility model can be achieved.
