In this dual-determination mode of capacitance sensing and photodetection, the accuracy of starting the laser 20, the accuracy and reliability of starting the laser 20, and the safety of the user can be improved, and the laser medical and cosmetic device can be prevented from being triggered by mistake.
[0046] Optionally, the laser medical and cosmetic device further comprises a circuit board 60, the photodetector 40 comprises at least one, and the photodetector 40 is electrically connected to the circuit board 60. The circuit board 60 is arranged in the refrigeration sensing structure 30, for example, can be connected to the inner end face of the refrigeration sensing structure 30 close to the fixing member 10.
[0047] The circuit board 60 can be fixed on the refrigeration sensing structure 30 by means of screws, adhesives, buckles, or connection welding, the circuit board 60 can be connected to the plug 92 through the wire 91, the plug 92 can be fixed on the side of the refrigeration sensing structure 30 close to the fixing member 10, and the plug 92 can be electrically connected to the controller 50 through the cable assembly 93.
[0048] In the embodiment, the refrigeration sensing structure 30 can realize capacitance detection in the following two ways:
[0049] In a first possible implementation, as shown in FIGS. 3 and 5, the refrigeration sensing structure 30 includes a refrigeration head 31 and a capacitive probe 94 electrically connected with the refrigeration head 31, the capacitive probe 94 is arranged on the circuit board 60 and electrically connected with the controller 50, and is configured to detect a capacitive signal generated after the refrigeration head 31 contacts the human skin and send the capacitive signal to the controller 50. At this time, the refrigeration head 31 can be used for refrigeration on one hand, and is electrically connected with the capacitive probe 94 and used for capacitive sensing on the other hand. At this time, the refrigeration head 31 is electrically connected with the capacitive probe 94, and the capacitive probe 94 is configured to detect a capacitive signal generated after the treatment surface 312 of the refrigeration head 31 contacts the human skin and send the capacitive signal to the controller 50.
[0050] Optionally, the refrigeration head 31 has an action surface 311 and a treatment surface 312, the detection light beam emitted by the photodetector 40 is emitted from the light emission area of the action surface 311, and the laser beam emitted by the laser 20 is emitted from the treatment surface 312.
[0051] Please refer to FIGS. 2 and 3, in the embodiment, the action surface 311 is annularly arranged at the outer periphery of the treatment surface 312, the treatment surface 312 is configured to transmit the laser beam, and the action surface 311 is configured with a light emission area for transmitting the detection light beam or the reflected light beam.
[0052] It should be noted that the action surface 311 can be a part of the refrigeration head 31, that is, the action surface 311 is integrally arranged with the refrigeration head 31. At this time, the light emission area of the action surface 311 can be a light transmission area (for example, a light transmission hole is opened at the position corresponding to the photodetector 40, or a light transmission hole is opened at the position corresponding to the photodetector 40 and a light transmission material is filled in the light transmission hole, or a light transmission hole is opened at the position corresponding to the photodetector 40 and a corresponding optical filter 80 is arranged in the light transmission hole) opened at the position corresponding to the photodetector 40.
[0053] In this case, the distribution of the photodetector 40 can at least include the following two ways:
[0054] In the first arrangement, the photodetector 40 includes two, and the orthographic projection of the two photodetectors 40 on the refrigeration head 31 is located on the action surface 311, as shown in FIG. 3. That is, both of the two photodetectors 40 are located on the action surface 311. For example, when the treatment surface 312 is in a rectangular distribution, the two photodetectors 40 can also be distributed at two opposite corners of the action surface 311; for another example, when the treatment surface 312 is in a shape other than a rectangle and is symmetrically arranged, the two photodetectors 40 can also be symmetrically distributed on the action surface 311; for another example, when the treatment surface 312 is in a non-symmetrically arranged shape, the two photodetectors 40 can also be uniformly distributed on the action surface 311.
[0055] In the second arrangement, the photodetector 40 includes a plurality of photodetectors 40, and the orthographic projection of the plurality of photodetectors 40 on the cooling head 31 is uniformly distributed on the action surface 311. The number of the plurality of photodetectors 40 is greater than or equal to 3. For example, the number of the photodetector 40 can be three, four, or five, etc. That is, when the treatment surface 312 is rectangularly distributed, the number of the photodetector 40 can be four, and the four photodetectors 40 can be distributed at the four corners of the action surface 311.
[0056] Of course, the diagonal distribution and the uniform distribution of the photodetector 40 are only examples, and the distribution mode can improve the accuracy and reliability of the photodetection. In other embodiments, other arrangement modes can also be selected as needed.
[0057] In the second feasible implementation, as shown in FIGS. 1, 2, and 4, the cooling induction structure 30 includes the cooling head 31 connected to one side of the fixing member 10, the capacitance induction member 32 connected in the cooling head 31, and the capacitance detector 94 electrically connected with the capacitance induction member 32. The capacitance detector 94 is arranged on the circuit board 60 and electrically connected with the controller 50. The capacitance detector 94 is used to detect the capacitance signal generated by the capacitance induction member 32 after contacting the human skin and send the capacitance signal to the controller 50.
[0058] At this time, the cooling head 31 can be used for cooling, and the capacitance induction member 32 is electrically connected with the capacitance detector 94 and is used for capacitance induction. At this time, after the action surface 311 of the cooling head 31 contacts the human skin, the capacitance induction member 32 can cooperate with the human skin to change the capacitance, so that the capacitance detector 94 acquires the capacitance signal corresponding to the capacitance change and sends the capacitance signal to the controller 50.
[0059] In this implementation, the cooling head 31 also has the action surface 311 and the treatment surface 312. The detection light beam emitted by the photodetector 40 is emitted from the action surface 311, and the laser beam emitted by the laser 20 can be emitted from the treatment surface 312. The distribution of the photodetector 40 can at least include the following two modes:
[0060] In the first arrangement, the capacitance induction member 32 and the photodetector 40 each include one, and the orthographic projection of the capacitance induction member 32 and the photodetector 40 on the cooling head 31 is located on the action surface 311, as shown in FIG. 2. This distribution mode of the capacitance induction member 32 and the photodetector 40 can save the number of the capacitance induction member 32 and the photodetector 40, and can improve the accuracy of the contact judgment.
[0061] In the second arrangement, the capacitive sensing element 32 comprises one, the photodetector 40 comprises two, the orthographic projections of the two photodetectors 40 and the capacitive sensing element 32 on the working surface 311 are located on the working surface 311 respectively, and the lines connecting the capacitive sensing element 32 and the two photodetectors 40 form a triangle.
[0062] The lines connecting the capacitive sensing element 32 and the two photodetectors 40 form a triangle, for example, as shown in FIG. 1, when the treatment surface 312 is rectangular, the orthographic projections of the two photodetectors 40 on the working surface 311 can be diagonally distributed, and the orthographic projection of the capacitive sensing element 32 on the working surface 311 can be located at any one of the remaining two corners.
[0063] In addition, when the refrigeration sensing structure 30 comprises the capacitive sensing element 32, the capacitive sensing element 32 is a material with conductive properties. Alternatively, the capacitive sensing element 32 can be a probe, a metal strip, or a metal sheet, etc.
[0064] In order to avoid mechanical damage to the capacitive sensing element 32 or the influence of the external environment, the laser medical cosmetic device can alternatively further comprise a coating film 70 for coating the outer periphery of the capacitive sensing element 32. It should be noted that the coating film 70 should be selected from a material that can protect the capacitive sensing element 32 and can avoid affecting the normal capacitive sensing of the capacitive sensing element 32.
[0065] In addition, in order to avoid the interference of ambient light on the photodetector 40 and to achieve the effect of sealing and dustproof for the photodetector 40, in the embodiment, the laser medical cosmetic device can alternatively further comprise a filter 80 connected to the light exit area of the working surface 311 of the refrigeration sensing structure 30, as shown in FIGS. 1 to 3, the filter 80 is located on the light exit path of the photodetector 40, and the filter 80 is used to filter stray light.
[0066] The light exit area can be a light transmission hole provided on the working surface 311, and the filter 80 is arranged in the light transmission hole.
[0067] In addition, in order to facilitate disassembly, the refrigeration sensing structure 30 of the present application can alternatively be connected to the fixing member 10 by magnetic attraction or through a hinge. Of course, the above-mentioned magnetic attraction and hinge connection are only examples and are not a limitation of the present application. In other embodiments, screw, buckle, thread, guide rail, etc. can also be used for connection.
[0068] In the embodiment, the refrigeration head 31 is detachably connected to the fixing member 10, and the refrigeration head 31 can comprise a plurality of refrigeration heads 31. The plurality of refrigeration heads 31 are respectively used to emit laser spots of different forms.
[0069] In this way, the user can select a suitable refrigeration head according to the type of the laser spot needed to be emitted, so that the laser medical and cosmetic device can be suitable for a plurality of different application scenarios.
[0070] In addition, it should be noted that in the present embodiment, the light-emitting window piece and the treatment window piece can be respectively arranged at the light-emitting area of the acting surface 311 and the treatment surface 312.
[0071] In addition, it should be noted that in the present embodiment, the light-emitting window piece and the treatment window piece can be respectively arranged at the light-emitting area of the acting surface 311 and the treatment surface 312.
