TECHNICAL FIELD
[0001] The utility model relates to the field of medical apparatus and instruments, especially to an electrode head and a radio frequency skin treatment instrument containing the same. BACKGROUND
[0002] Radio frequency skin treatment instruments and other radio frequency devices are widely used in the field of beauty and skin treatment. The electrode sheet arranged at the electrode head emits high-frequency radio frequency energy to the skin, loads the radio frequency energy to the subcutaneous tissue, makes the subcutaneous tissue move at high frequency to generate heat, promotes the proliferation of collagen and the improvement of skin structure, and achieves the effect of tightening the skin, lightening fine lines and wrinkles, etc. Among them, the radio frequency skin treatment instrument with adsorption function sets a vacuum adsorption port at the electrode head. When the electrode head contacts the skin, the vacuum adsorption port adsorbs the skin into the vacuum adsorption port to increase the contact area between the electrode head and the skin. At the same time, the electrode sheet is arranged near the vacuum adsorption port to increase the contact area between the electrode sheet and the skin, thereby improving the ability to load radio frequency energy to the subcutaneous tissue and improving the treatment effect.
[0003] However, the current flowing through the electrode sheet is large, and the temperature of the skin may continue to rise during continuous use. The radio frequency skin treatment instrument with adsorption function adsorbs the skin near the vacuum adsorption port, which makes it difficult for the skin adsorbed by the vacuum to dissipate heat, and there is a risk of low-temperature scalding during continuous use.

The electrode sheet has a treatment surface for contacting the skin. The electrode head further includes a temperature sensor. The electrode sheet has a blind hole extending from a side opposite to the treatment surface to the inside of the electrode sheet. The bottom of the blind hole extends to a region close to the treatment surface. The detection end of the temperature sensor is fixed in the blind hole and is in thermal contact with the bottom of the blind hole.
[0007] The electrode head is provided with a vacuum suction port to have a vacuum suction capability, a blind hole extending to the inside of the electrode head is arranged on the side of the electrode sheet far from the treatment surface, the bottom of the blind hole extends to the area close to the treatment surface, and a temperature sensor is arranged at the position of the blind hole, so as to utilize the electrode sheet in contact with the skin as a medium for detecting the skin temperature, to realize continuous detection of the skin temperature in contact with the electrode sheet, thereby effectively avoiding the problem of low-temperature burn caused by the difficulty of heat dissipation of the suctioned skin. Specifically, compared with arranging the temperature sensor at other positions of the electrode head, the temperature sensor is arranged in the electrode sheet, on the one hand, considering that the electrode sheet is made of metal material, the response speed to temperature change is relatively fast, on the other hand, considering that the electrode sheet can maintain continuous contact with the skin during use, and the contact area is relatively large, which can objectively reflect the current temperature condition of the skin.
[0008] Preferably, the electrode head further comprises an electrode head shell, a surface of the electrode head shell has an inwardly recessed skin accommodating space, the vacuum suction port is formed at the bottom of the skin accommodating space, and the electrode sheet is arranged at the side of the skin accommodating space.
[0009] By arranging the electrode head shell and accommodating the vacuum suction port and the electrode sheet in the inwardly recessed skin accommodating space of the electrode head shell, the skin is suctioned to the bottom area of the skin accommodating space through the vacuum suction port, so that the skin is kept in close contact with the side of the skin accommodating space, the contact area of the electrode sheet and the skin is improved, and the treatment ability and temperature detection ability are improved.
[0010] Preferably, the treatment surface of the electrode sheet has a circular arc transition part, and the circular arc transition part transitions from the side of the skin accommodating space to the top of the skin accommodating space.

[0012] Preferably, the electrode sheet is detachably connected to the bottom of the skin accommodating space and covers at least part of the side of the skin accommodating space.

[0014] Preferably, the electrode sheet comprises a first electrode and a second electrode, the first electrode and the second electrode are different in polarity, and the first electrode and the second electrode are respectively arranged on the left and right sides of the vacuum suction port.
[0015] The electrode sheet comprises a first electrode and a second electrode, the positive and negative polarities of the first electrode and the second electrode are changed with the radio frequency of the radio frequency circuit, but the polarities of the first electrode and the second electrode are always different.

[0016] Preferably, a heat-conducting material is filled between the detection end of the temperature sensor and the bottom of the blind hole.
[0017] By filling the heat-conducting material between the detection end of the temperature sensor and the bottom of the blind hole, the contact area between the detection end and the bottom is improved, and the response degree of the temperature sensor to the temperature change of the electrode sheet is improved. Meanwhile, the filling of the heat-conducting material can also help the detection end of the temperature sensor to be better fixed at the position of the bottom of the blind hole, and the use durability of the electrode head is improved.
[0018] Preferably, the electrode sheet has at least two blind holes, and the two blind holes are symmetrically arranged on the electrode sheet.
[0019] By symmetrically arranging at least two blind holes on the electrode sheet, the installable positions of the temperature sensor are increased, so that the temperature sensor can be installed at multiple positions of the electrode sheet, and the universality of the electrode sheet can be improved.
[0020] Preferably, the blind hole is a circular hole.
[0021] By adopting the circular hole as the blind hole, compared with other shapes, on the one hand, the installation of the temperature sensor is more convenient, and on the other hand, the existence of edges and corners in the blind hole can also damage the temperature sensor.
[0022] Preferably, the material of the electrode sheet is aluminum alloy, and the thermal conductivity of the electrode sheet is greater than 100 W / m℃.
[0023] By selecting the aluminum alloy material with the thermal conductivity greater than 100 W / m℃ as the electrode sheet, the electric conductivity and the thermal conductivity of the electrode sheet are ensured, the temperature delay between the temperature change of the electrode sheet and the skin surface temperature is reduced, and the temperature of the contacted skin can be more accurately and quickly reflected.

[0052] The utility model is described below with reference to the preferred embodiments and drawings.
[0053] In combination Figure 1 , Figure 3 and Figure 5 , the electrode tip 10 applied to the radio frequency skin treatment instrument as a structure for contacting the skin of the user, which comprises a vacuum suction port 100 and two electrode sheets 200. Among them, the two electrode sheets 200 are respectively a first electrode 210 and a second electrode 220, the first electrode 210 and the second electrode 220 are arranged close to the vacuum suction port 100, and both have a treatment surface for contacting the skin, the polarities of the first electrode 210 and the second electrode 220 are different, and the positive and negative polarities are changed with the radio frequency of the radio frequency circuit, when the first electrode 210 is positive, the second electrode 220 is negative, and when the first electrode 210 is negative, the second electrode 220 is positive, so that when the first electrode 210 and the second electrode 220 contact the skin through the treatment surface, an electric current is generated at the contacted skin.
[0054] In the embodiment, to solve the problem that the current radio frequency skin treatment instrument is easy to cause low-temperature scald in use, the electrode tip 10 further comprises a temperature sensor 300 arranged corresponding to the two electrode sheets 200. Here, taking the second electrode 220 as an example, as shown in Figures 3-5As shown, the electrode sheet 200 has a blind hole 222 extending from the side relatively far away from the treatment surface 221 to the interior of the electrode sheet 200, the hole bottom of the blind hole 222 extends to the area relatively close to the treatment surface 221, and the detection end of the temperature sensor 300 is fixed in the blind hole 222 and in heat conduction contact with the hole bottom of the blind hole 222.
[0055] In the case where the electrode head 10 is provided with a vacuum suction port 100 to have vacuum suction capability, by providing a blind hole 222 extending to the interior of the electrode head 10 on the side of the electrode sheet 200 relatively far away from the treatment surface 221, extending the hole bottom of the blind hole 222 to the area relatively close to the treatment surface 221, and arranging a temperature sensor 300 at the position of the blind hole 222, the electrode sheet 200 in contact with the skin is used as a medium for detecting the skin temperature, and continuous detection of the skin temperature in contact with the electrode sheet 200 is realized, thereby effectively avoiding the problem of low-temperature burns caused by the difficulty of heat dissipation of the suctioned skin.
[0056] Specifically, compared with arranging the temperature sensor 300 at other positions of the electrode head 10, the temperature sensor 300 is arranged in the interior of the electrode sheet 200, on the one hand, considering that the electrode sheet 200 is made of metal material and has a relatively fast response speed to temperature changes, and on the other hand, considering that the electrode sheet 200 can maintain continuous contact with the skin during use and has a relatively large contact area, which can objectively reflect the current temperature condition of the skin.
[0057] In the embodiment, the detection end of the temperature sensor 300 is arranged in the first electrode 210 and the second electrode 220 to detect the temperature of the two electrode sheets 200, respectively. In other embodiments, the corresponding arrangement relationship between the temperature sensor 300 and the electrode sheet 200 can also be set according to actual design and detection requirements. For example, in the case where the electrode head 10 is provided with the first electrode 210 and the second electrode 220 with different polarities as in the embodiment, one of the electrode sheets 200 is selected, and the temperature sensor 300 is arranged in the blind hole 222 in the interior of the electrode sheet 200. In the case where the electrode head 10 has a plurality of first electrodes 210 or a plurality of second electrodes 220, the temperature sensor 300 can be arranged in each first electrode 210 or second electrode 220 correspondingly. The specific structure setting scheme can be flexibly adjusted according to actual design and detection requirements.
[0058] As shown in FIG. 2, the electrode head 10 is provided with a vacuum suction port 100, and the electrode head 10 is provided with a first electrode 210 and a second electrode 220. Figure 5As shown, in this embodiment, each electrode plate 200 has two blind holes 222, which are symmetrically arranged on both sides of the electrode plate 200. In actual use, only one blind hole 222 is selected to install the temperature sensor 300. The purpose of having two blind holes 222 is to improve the versatility of the electrode plate 200, requiring only one electrode plate 200 to meet the needs of installing the temperature sensor 300 in different locations. Furthermore, screw holes 223 are further provided on both sides of the two blind holes 222 for mounting and fixing the electrode plate 200.
[0059] like Figure 1 As shown, in this embodiment, the electrode head 10 also includes an electrode head housing 500. The surface of the electrode head housing 500 has an inwardly recessed skin receiving space 510. A vacuum suction port 100 is formed at the bottom 513 of the skin receiving space, and an electrode sheet 200 is arranged on the side 512 of the skin receiving space.
[0060] By providing an electrode head housing 500 on the electrode head 10, and accommodating a vacuum suction port 100 and an electrode pad 200 within a skin-accommodating space 510 recessed inward within the electrode head housing 500, the skin is suctioned to the bottom 513 of the skin-accommodating space through the vacuum suction port 100, thereby keeping the skin in close contact with the side 512 of the skin-accommodating space, increasing the contact area between the electrode pad 200 and the skin, and enhancing the treatment capability and temperature detection capability.
[0061] Combination Figure 1 and Figure 3 In this embodiment, the treatment surface 221 of the electrode pad 200 has an arc transition portion 2210, which transitions from the side portion 512 of the skin receiving space to the top portion 511 of the skin receiving space.
[0062] By providing an arc transition portion 2210 on the treatment surface 221 of the electrode pad 200, and having the arc transition portion 2210 in contact with the skin, damage to the skin surface can be reduced when the skin is adsorbed into the skin-accommodating space 510 through the vacuum adsorption port 100.
[0063] like Figure 3 As shown, in order to achieve the connection between the electrode pad 200 and the electrode head housing 500, in this embodiment, the screw holes 223 of the two electrode pads 200 are respectively connected to the bottom 513 of the skin receiving space of the electrode head housing 500 by screws 600, so as to achieve the detachable connection between the electrode pad 200 and the skin receiving space 510 by means of screw 600 connection, and at least cover a part of the side of the skin receiving space 510, so as to achieve the purpose of fitting with the skin located on the side 512 of the skin receiving space.
[0064] The electrode sheet 200 is detachably connected to the bottom 513 of the skin accommodating space by the screw 600, so as to facilitate the disassembly and assembly of the electrode sheet 200 relative to the electrode head shell 500. At the same time, the electrode sheet 200 extends upwards from the connected bottom 513 of the skin accommodating space and covers at least a part of the side of the skin accommodating space 510, so that the electrode sheet 200 is in contact with the skin on the side 512 of the skin accommodating space, thereby increasing the contact area of the electrode sheet with the skin. Of course, in other embodiments, other detachable connection schemes other than the screw 600 connection can be used to realize the installation of the electrode sheet 200 relative to the bottom 513 of the skin accommodating space, and the specific implementation scheme is not described here.
[0065] As shown in the drawings, Figure 1 In this embodiment, the two electrode sheets 200 provided on the electrode head 10 are a radio frequency negative electrode 210 and a radio frequency positive electrode 220, respectively, and the radio frequency negative electrode 210 and the radio frequency positive electrode 220 are located on the left and right sides of the vacuum suction port 100, respectively.
[0066] By arranging the radio frequency negative electrode 210 and the radio frequency positive electrode 220 on the left and right sides of the vacuum suction port 100, respectively, a reasonable layout of the internal elements of the electrode head 10 is realized, so that the radio frequency negative electrode 210 and the radio frequency positive electrode 220 have a relatively far distance between them, thereby increasing the effective area of the electrode head 10 on the skin.
[0067] As shown in the drawings, Figure 3 In this embodiment, a thermally conductive material 400 is filled between the detection end of the temperature sensor 300 and the hole bottom of the blind hole 222.
[0068] By filling the thermally conductive material 400 between the detection end of the temperature sensor 300 and the hole bottom of the blind hole 222, the contact area between the detection end and the hole bottom is increased, and the response degree of the temperature sensor 300 to the temperature change of the electrode sheet 200 is improved. At the same time, the filling of the thermally conductive material 400 can also help the detection end of the temperature sensor 300 to be better fixed at the position of the hole bottom of the blind hole 222, thereby improving the service durability of the electrode head 10.
[0069] As shown in the drawings, Figure 5 The electrode sheet 200 has at least two blind holes 222, and the two blind holes 222 are symmetrically arranged on the electrode sheet 200.
[0070] By symmetrically arranging at least two blind holes 222 on the electrode sheet 200, the installable positions of the temperature sensor 300 are increased, so that the temperature sensor 300 can be installed at multiple positions of the electrode sheet 200, and the versatility of the electrode sheet 200 can be improved.
[0071] In this embodiment, the material of the electrode sheet 200 is aluminum alloy, and the thermal conductivity of the electrode sheet 200 is greater than 100 W / m℃.
[0072] By selecting an aluminum alloy material with a thermal conductivity greater than 100 W / m℃ as the electrode sheet 200, the electrical conductivity and thermal conductivity of the electrode sheet 200 are ensured, the temperature delay between the temperature of the electrode sheet 200 and the temperature change of the skin surface is reduced, and the temperature of the contacted skin is more accurately and quickly reflected.
[0073] The utility model also provides a kind of radio frequency skin treatment appearance, it includes the electrode head 10 as described above, by being set up blind hole 222 in the electrode sheet 200 of this electrode head 10, and temperature sensor 300 is arranged in blind hole 222 to detect contact skin temperature, prevent skin from being low temperature scald due to adsorption difficult heat dissipation.
