Detailed Description

To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Exemplary embodiments of the invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Example one

This embodiment provides a therapeutic instrument. Referring to fig. 1, fig. 1 is a schematic structural diagram of the therapeutic apparatus provided in this embodiment, and the therapeutic apparatus includes a housing 2 and an electrode head 1 mounted outside the housing 2. The electrode head 1 includes a support sheet 11 and a plurality of electrode tabs 12 fixed to the support sheet 11. Here, the support plate 11 is made of an insulating and good heat conducting material, and preferably, the support plate 11 is made of a ceramic material, the thermal conductivity of the ceramic material is generally above 20W/m.k, even up to 200W/m.k, while the thermal conductivity of the common plastic is generally below 0.1W/m.k, and the thermal conductivity of the ceramic material is 200 or even 2000 times higher than that of the common plastic. The support sheet 11 thus has good thermal conductivity. In fig. 1, an upward surface of the support piece 11 is a heat conduction surface 111, a downward surface thereof is a mounting surface 112, and peripheral side surfaces of upper and lower side edges of the support piece 11, which are connected to the heat conduction surface 111 and the mounting surface 112, respectively, are heat dissipation surfaces 113. The mounting surface 112 is fixedly connected to the housing 2, and the heat dissipation surface 113 is exposed out of the housing 2. Here, a plurality of electrode pads 12 are fixed on the heat conducting surface 111 of the supporting plate 11 in an array, specifically referring to fig. 2, fig. 2 is a schematic top view of the therapeutic apparatus in this embodiment, it can be seen that the heat conducting surface 111 of the supporting plate 11 is a plane, and a plurality of electrode pads 12 are arranged on the heat conducting surface 111 in an oval array, it can be understood that the plurality of electrode pads 12 in this embodiment are located on the same horizontal plane. During the use of the therapeutic apparatus, the heat conducting surface 111 is directly contacted with the skin, so that the electrode pads 12 can be directly contacted with the skin to ensure the best radio frequency effect. Moreover, the heat generated by the skin surface tissue and the electrode sheet 12 during the treatment process can be rapidly diffused to the outside or the heat dissipation surface 113 through the heat conduction surface 111. It should be noted that, during the moving of the therapeutic apparatus, a portion of the heat conducting surface 111 may be exposed to the air, and at this time, the heat at the skin surface tissue and the heat generated by the electrode sheet 12 can be diffused to the outside through the heat conducting surface 111. Meanwhile, the electrode sheets 12 arranged in an array form a finer electric field, so that the whole area of the skin covered by the supporting sheet 11 can be taken care of, and the radio frequency energy is uniformly applied to each covered area of the skin. In addition, because the heat dissipation surface 113 is arranged on the peripheral side of the supporting sheet 11, the heat dissipation surface 113 can be exposed to the air during the use process, so that the heat at the skin surface tissue can be efficiently and quickly diffused to the outside through the heat dissipation surface 113 of the supporting sheet 11 during the treatment process, and the skin surface tissue is ensured not to be lost. Compared with the common single-electrode and double-electrode skin beautifying instrument, the energy distribution of the radio frequency heads arranged in a dot matrix manner is more uniform, and meanwhile, the supporting sheet 11 made of high-thermal-conductivity material can quickly dissipate heat, so that the qualitative leap on the protection of the skin of the epidermis is achieved. Referring to fig. 3, fig. 3 is a schematic diagram of the line connection of the therapeutic apparatus provided in this embodiment, a signal generator, a switch circuit and a control unit are arranged in the housing 2, the plurality of electrode plates 12 are electrically connected to the signal generator through the switch circuit, and the control unit is electrically connected to the switch circuit. The signal generator is used for generating a treatment signal. Where the treatment signals comprise different types of electrical signals, it will be appreciated that the signal generator is one type of power source for outputting electrical signals for treatment. The switch circuit includes a plurality of switches, each of which is connected to one or more of the electrode pads 12, and each of the electrode pads 12 is connected to at least one of the switches. In this way, one switch can simultaneously control one or more electrode plates 12 to be switched on or off with the signal generator, and the on or off state of the same electrode plate 12 with the signal generator bracket can be controlled by different switches. The control unit is a microprocessor which can control the open and close states of a plurality of switches in the switch circuit, so that the control unit can control at least one electrode in a plurality of electrodes to be independently connected with or disconnected from the signal generator through the switch circuit. That is, the control unit can individually control the on or off state of one or more electrode pads 12 on the support sheet 11 and the signal generator. In this way, the control unit can control the opening and closing of one or more electrode plates 12 in the local area, thereby realizing targeted heat dissipation and temperature reduction in the local area.

Further, the support sheet 11 has a plurality of wire holes penetrating through the support sheet 11 along the thickness direction, and the plurality of wire holes are respectively in one-to-one correspondence with the plurality of electrode sheets 12; and a lead is arranged in each wire passing hole in a penetrating manner, one end of each lead is electrically connected to the corresponding electrode plate 12, and the other end of each lead is electrically connected to the switch circuit. It should be noted that the thickness direction is parallel to a direction from a side where the heat conduction surface 111 of the support sheet 11 is located to a side where the mounting surface 112 of the support sheet 11 is located. Thus, each electrode plate 12 is electrically connected to the signal generator through the corresponding lead, which is beneficial to simplifying the lead wiring of the electrode plate 12 and preventing the winding of the wire harness.

In other embodiments, the supporting sheet 11 may also be made of other insulating and heat-conducting materials, for example, more thermal conductive gaskets TGP10000ULM are used in industry for improving heat conductivity, and the thermal conductivity thereof reaches 10W/m. It is to be understood that in the industry, high thermal conductivity materials are mostly used in macroscopic structures, such as 5G emitter tables, and are rarely used for cooling the microstructures, where the inventive use of a thermal conductive gasket TGP for the manufacture of the support sheet 11 of the electrode head 1 achieves the purpose of improving the heat dissipation properties of the support sheet 11. Of course, the support sheet 11 may also be made of a heat-conducting silicone sheet, a heat-conducting insulating rubber, or a graphene material subjected to an insulating treatment.

In other embodiments, the heat conducting surface 111 of the supporting plate 11 may be an arc surface, a ring surface, a curved surface, etc., and may be designed according to the location to be treated.

In other embodiments, the plurality of electrode pads 12 on the support plate 11 may be arranged in various shapes, such as a circular array, a rectangular array, a trapezoidal array, a triangular array, an annular array, a digital array, a letter-shaped array, etc., and may also be an array in an irregular pattern, which may be specifically designed according to the part to be treated.

In other embodiments, the electrode head 1 is fixed in the housing 2 in a snap-fit manner, in which case the heat radiating surface 113 of the electrode head 1 is enclosed by the housing 2, which, although reducing the heat radiating properties to some extent, may enhance the stability of the connection between the electrode head 1 and the housing 2. In this case, the heat-conducting surface 111 of the electrode tip 1 serves as a main heat dissipation path, and has the advantage of high heat dissipation efficiency compared to the prior art.

Example two

The therapeutic apparatus in this embodiment is different from the therapeutic apparatus provided in the first embodiment only in that: a plurality of first air flow channels 114 penetrating along a first direction are concavely arranged on the mounting surface 112 of the support sheet 11; the first direction is perpendicular to the thickness direction of the support sheet 11; the thickness direction is parallel to a direction from a side where the heat conduction surface 111 of the support sheet 11 is located toward a side where the mounting surface 112 of the support sheet 11 is located. Referring to fig. 4 and 5, fig. 4 is a schematic structural view of the therapeutic apparatus provided in this embodiment, and in fig. 4, the first direction can be understood as a direction extending from outside the paper to inside the paper perpendicularly; fig. 5 is a schematic bottom view of the electrode head 1 of the therapeutic apparatus provided in this embodiment. As can be seen in fig. 4 and 5, a plurality of the first air flow channels 114 are arranged at equal intervals, and adjacent two of the first air flow channels 114 are separated by a supporting strip 115. When the support plate 11 is mounted to the housing 2, only the bottom of the support bar 115 is attached to the housing 2 (see fig. 4), so that the mounting surface 112 does not need to be completely connected to the housing 2, in other words, a portion of the mounting surface 112 is exposed to the air. Compared with the first embodiment, in the present embodiment, a plurality of first air flow channels 114 communicating with the outside are formed at the mounting surface 112 of the supporting sheet 11, so that the heat transferred from the skin surface tissue to the supporting sheet 11 can be diffused not only to the outside through the heat dissipating surface 113, but also to the outside through the concave mounting surface 112. More importantly, during the treatment process, a fast flowing air flow can be formed in the first air flow channel 114 during the process of moving the electrode tip 1, and the heat of the supporting sheet 11 can be rapidly dissipated by the convection of the air, thereby enhancing the heat dissipation effect.

EXAMPLE III

The therapeutic apparatus of the present embodiment is different from the therapeutic apparatus of the second embodiment only in that: the mounting surface 112 of the support sheet 11 is further concavely provided with a plurality of second air flow channels 116 penetrating along a second direction; the second direction is perpendicular to the thickness direction; each of the first air flow passages 114 is in cross communication with a plurality of the second air flow passages 116, respectively. Referring to fig. 6, fig. 6 is a schematic bottom view of the electrode head 1 of the therapeutic apparatus provided in this embodiment. The mounting surface 112 is concavely provided with a first air flow channel 114 and a second air flow channel 116 which are staggered transversely and longitudinally, and correspondingly, a plurality of supporting legs 117 arranged in an array are formed on the lower side of the supporting sheet 11, when the supporting sheet 11 is mounted on the housing 2, only the bottom of the supporting legs 117 is attached to the housing 2, so that the mounting surface 112 does not need to be completely connected with the housing 2, in other words, most of the mounting surface 112 is exposed to air. Compared with the embodiment, firstly, the area of the mounting surface 112 exposed to the air can be further increased, and the heat dissipation effect of the supporting sheet 11 can be improved. In addition, the air convection effect at one side of the mounting surface 112 of the support plate 11 in the process of moving the electrode head 1 can be further enhanced, the flow and diffusion of the hot air between the mounting surface 112 and the housing 2 can be accelerated, and the heat dissipation efficiency can be further improved.

Example four

The therapeutic apparatus of the present embodiment is different from the therapeutic apparatus of the second embodiment only in that: the heat dissipation device includes a plurality of heat dissipation fins 13 arranged at intervals along the extending direction of the first air flow channel 114. Referring to fig. 7, fig. 7 is a schematic bottom view of the electrode head 1 of the therapeutic apparatus provided in this embodiment. Each of the first air flow channels 114 accommodates a row of a plurality of heat dissipation fins 13 arranged at equal intervals, and here, the heat dissipation fins 13 may be made of a metal sheet having a heat conduction performance superior to that of the support sheet 11. In this way, the heat of the supporting plate 11 can be quickly absorbed by the heat sink 13 and more efficiently diffused into the first air flow channel 114, thereby enhancing the heat dissipation effect of the supporting plate 11. In order to reduce the obstruction of the heat sink 13 to the gas flow in the first gas flow channel 114, a plurality of ventilation holes may be formed in the heat sink 13. Meanwhile, the height of the heat sink 13 is smaller than the height of the first air flow channel 114 (i.e., the height of the supporting bars 115), so that the heat sink 13 is further prevented from obstructing the air flow in the first air flow channel 114.

In some other embodiments, a plurality of rows of the heat dissipation fins 13 may be disposed in the first air flow channel 114, and two adjacent rows of the heat dissipation fins 13 are spaced apart by a certain distance.

EXAMPLE five

The therapeutic apparatus of the present embodiment is different from the therapeutic apparatus of the second embodiment only in that: the heat dissipation device includes a cooling pipe 14 passing through the plurality of first air flow channels 114 in a winding manner. Referring to fig. 8, fig. 8 is a schematic bottom view of the electrode head 1 of the therapeutic apparatus provided in this embodiment. The cooling pipe 14 is continuously S-shaped and penetrates through the plurality of first air flow channels 114, the liquid inlet 141 and the liquid outlet 142 of the cooling pipe 14 are respectively connected to a cooling liquid supply device (not shown), the liquid flowing out from the liquid outlet 142 flows into the cooling liquid supply device, and flows into the cooling pipe 14 from the liquid inlet 141 after heat exchange and cooling, and the heat of the air in the first air flow channels 114 can be taken away in the flowing process of the cooling liquid in the cooling pipe, so that the temperature of the air in the first air flow channels 114 can be rapidly reduced, the heat of the support sheet 11 can be rapidly diffused to the first air flow channels 114 from the concave mounting surface 112, and the heat dissipation effect of the support sheet 11 is enhanced.

The therapeutic apparatus in this embodiment is different from the therapeutic apparatus provided in the first embodiment only in that: the side wall of the shell 2 connected with the support piece 11 is provided with a plurality of grooves 21 which are through along a first direction. Referring to fig. 9, fig. 9 is a schematic structural view of the therapeutic apparatus provided in this embodiment. As shown in fig. 9, since the upper sidewall of the housing 2 is provided with a plurality of through grooves 21, when the supporting plate 11 is mounted on the upper sidewall of the housing 2, the mounting surface 112 of the supporting plate 11 is not completely attached to the housing 2, that is, a part of the mounting surface 112 is exposed to the air, so that the heat transferred from the skin surface tissue to the supporting plate 11 can be diffused to the outside through the heat conducting surface 111 and the heat dissipating surface 113, and can also be diffused to the outside through the mounting surface 112. More importantly, during the treatment process, a fast flowing air flow can be formed in the groove 21 during the movement of the treatment apparatus, and the heat of the support sheet 11 can be rapidly dissipated by the convection of the air, thereby enhancing the heat dissipation effect.
