Description

Technical Field

[0001] The present invention relates to the technical field of beauty electronic equipment, and in particular to an elastic electrode of a radio frequency beauty instrument. Background Art

[0002] A radiofrequency beauty device uses radiofrequency technology for skin beautification. It works by utilizing electromagnetic induction generated by a high-frequency alternating electric field within skin tissue, creating a rotating electric field and thermal effect within the tissue. The high-frequency waves generated by the device penetrate the skin's surface and act directly on the dermis, heating collagen fibers. This promotes collagen contraction and regeneration, increasing skin elasticity and improving skin quality.

[0003] For example, the radio frequency beauty instrument disclosed in patent number CN215079568U, combined with the accompanying drawings Figure 1 As shown, the electrode heads 1 to 6 (41-46) contact the skin to generate heat, thereby achieving a skin beauty effect. However, when this device is used, it is difficult for multiple electrodes to contact the skin (chin, forehead, corners, etc.) at the same time, resulting in unsatisfactory implementation effect.

[0004] Another example is the elastic electrode assembly and the electronic cigarette with the elastic electrode assembly disclosed in patent number CN203555167U, combined with the accompanying drawings Figure 3 As shown, the contact electrode 3 is connected to the compression spring 4, the fixing sleeve 1 and the insulating sleeve 2 to achieve the telescopic effect. However, this structure is combined with the above-mentioned radio frequency beauty instrument to form an elastic electrode head. During use, the spring is easily unevenly stressed, resulting in poor physical sensation for the user. In addition, this coupling method has a sealing problem, which is prone to water ingress and causes jamming.

[0005] Therefore, there is an urgent need for an elastic electrode for a radio frequency beauty device that can solve one or more of the above problems. Summary of the Invention

[0006] To address one or more problems existing in the prior art, the present invention provides an elastic electrode for a radio frequency beauty device. The present invention employs the following technical solutions to address the aforementioned problems: an elastic electrode for a radio frequency beauty device, comprising: an electrode assembly, the electrode assembly being provided with a reed group, the reed group being mounted on a support, the reed group being provided with two conductive reeds, the two conductive reeds being symmetrically arranged, and a spacing being provided between the two conductive reeds;

[0007] The electrode assembly is provided with a conductive key cover, the conductive key cover is provided with a receiving cavity, and the reed group is squeezed and loaded into the receiving cavity;

[0008] When the conductive key cover is subjected to external force and moves downward along the reed group, the two conductive reeds are compressed and produce elastic deformation. When the external force on the conductive key cover is eliminated, the two conductive reeds begin to reset and drive the conductive key cover to move upward and reset.

[0009] Furthermore, notches are provided on both sides of the conductive key cover, and the notches are connected to the receiving cavity;

[0010] The conductive spring is provided with a vertical section, the lower end of the vertical section is mounted on the support, the upper end of the vertical section is connected to the top section, the free end of the top section is connected to the first flexure section, the first flexure section extends downward, the free end of the first flexure section is connected to the second flexure section, a concave curved surface section is formed between the first flexure section and the second flexure section, the concave curved surface section is formed with a concave curved surface, a distance is provided between the concave curved surface section and the vertical section, the free end of the second flexure section extends outward, the free end of the second flexure section is connected to a tail section, the free end of the tail section extends outward, the tail section is formed with an inclined surface, and the tail section is installed in the slot;

[0011] The first flexure sections of the two conductive springs are squeezed into the conductive key cover, the first flexure sections are always in contact with the inner side surface of the receiving cavity, and the width of the second flexure section is greater than the width of the notch;

[0012] The tail section is connected to the notch and supports the conductive key cover. When the conductive key cover is pulled out, the free end of the second flexure section and the clamping joint of the receiving cavity generate an obstructive force, making it difficult for the conductive key cover to be pulled out.

[0013] When the conductive key cover is subjected to external force and moves downward along the reed group, the second flexure section and the tail section are compressed and bent inward, the concave curved surface section moves inward, the distance between the concave curved surface section and the vertical section is reduced, and the vertical sections of the two conductive reeds are bent and approach each other.

[0014] Furthermore, the top section forms a plane, which cooperates with the top surface of the storage cavity; the width of the slot is equal to or greater than the width of the tail section; a curved surface is formed between the top section and the first flexure section; and a curved surface is formed between the vertical section and the top section.

[0015] Furthermore, the opening of the receiving cavity is narrower than the inner cavity thereof, and the receiving cavity is in a constricted shape.

[0016] The beneficial value achieved by the present invention is as follows: the present invention realizes the elastic electrode function of a radio frequency beauty instrument by connecting a reed group and a conductive key cover to form an electrode assembly and installing it on a support, and supplying power through the circuit inside the support; through the structure of the reed group and the conductive key cover themselves and the connection structure therebetween, as well as the sealed connection between the reed group and the support, the conductive key cover is fixed in a limited position and elastically expands and contracts during movement.

The above greatly improves the practical value of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] To make the above-mentioned objects, features, and advantages of the present invention more readily understood, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art can make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] like Figures 1-6 As shown, the present invention discloses an elastic electrode of a radio frequency beauty instrument, which includes: an electrode assembly 2, wherein the electrode assembly 2 is provided with a reed group 4, wherein the reed group 4 is mounted on a support 1, and wherein the reed group 4 is provided with two conductive reeds 40, wherein the two conductive reeds 40 are symmetrically arranged, and a distance is provided between the two conductive reeds 40;

[0028] The support 1 is provided with a mounting groove 10, and the lower end of the conductive spring 40 is sealed and installed in the mounting groove 10. The support 1 is provided with electronic components such as a drive board, a control board, and a battery. The conductive spring 40 is powered by the electronic components in the support 1;

[0029] The support 1 may be provided with a plurality of electrode assemblies 2, and the electrode assemblies 2 may also be installed at different heights for convenient use.

[0030] The electrode assembly 2 is provided with a conductive key cover 3, and the conductive key cover 3 is provided with a receiving cavity 30, and the reed group 4 is squeezed and installed in the receiving cavity 30;

[0031] When the conductive key cover 3 is subjected to external force and moves downward along the reed group 4, the two conductive reeds 40 are compressed and produce elastic deformation. When the external force on the conductive key cover 3 is eliminated, the two conductive reeds 40 begin to reset and drive the conductive key cover 3 to move upward and reset.

[0032] Specifically, combined Figure 3-Figure 5 As shown, notches 31 are provided on both sides of the conductive key cover 3, and the notches 31 are connected to the receiving cavity 30;

[0033] The conductive spring 40 is provided with a vertical section 41, the lower end of the vertical section 41 is mounted on the support 1, the upper end of the vertical section 41 is connected to the top section 42, the free end of the top section 42 is connected to the first flexure section 43, a curved surface 421 is formed between the vertical section 41 and the top section 42, the first flexure section 43 extends downward, a curved surface 421 is formed between the top section 42 and the first flexure section 43, the free end of the first flexure section 43 is connected to the second flexure section 44 Next, a concave curved surface section 431 is formed between the first flexure section 43 and the second flexure section 44. The concave curved surface section 431 has a concave curved surface. A distance is provided between the concave curved surface section 431 and the vertical section 41. The free end of the second flexure section 44 extends outward. The free end of the second flexure section 44 is connected to a tail section 45. The free end of the tail section 45 extends outward. The tail section 45 has an inclined surface. The tail section 45 is installed in the slot 31.

[0034] The first flexure sections 43 of the two conductive springs 40 are squeezed into the conductive key cover 3 , and the first flexure sections 43 are always in contact with the inner side surface of the receiving cavity 30 . The width of the second flexure section 44 is greater than the width of the notch 31 .

[0035] Combine Figure 6 As shown, the left side is the initial state and the right side is the extreme pressed state. After installation, the first flexure sections 43 of the two conductive springs 40 are squeezed into the conductive key cover 3, and the first flexure sections 43 are always in contact with the inner side surface of the storage cavity 30.

[0036] It should be noted that the width of the notch 31 is equal to or greater than the width of the tail section 45, so that the tail section 45 is connected to the notch 31 and supports the conductive key cover 3. When the conductive key cover 3 is pulled outward, the free end of the second flexure section 44 and the engagement with the receiving cavity 30 generate an obstructive force, that is, its edge engages with the inner side surface, and the second flexure section 44 has a tendency to expand outward under the action of elastic force. Combined with the reaction force generated by the compression of the first flexure section 43, this makes it difficult to pull out the conductive key cover 3, but easy to press in; ultimately, the conductive key cover 3 can be well engaged and fixed on the reed assembly 4.

[0037] Further, combined with Figure 3 As shown, the opening of the storage cavity 30 is narrower than its inner cavity, and the storage cavity 30 is in a constricted shape (after assembly, the lower end of the conductive key cover 3 is clamped with a tool to form a constriction. Alternatively, the lower end of the conductive key cover 3 may be heated before assembly and then mounted on the reed assembly 4). This makes it more difficult to remove the conductive key cover 3. Of course, the storage cavity 30 may also be in a straight-up or straight-down type. The top section 42 is formed with a flat surface, and the top surface of the storage cavity 30 is also flat. This flat surface cooperates with the top surface of the storage cavity 30, so that when the conductive key cover 3 moves to the extreme position, the conductive key cover 3 can fit the top surface of the reed assembly 4, thereby preventing the reed assembly 4 from swinging inside the conductive key cover 3, which would cause overall instability and discomfort when pressing.

[0038] Furthermore, when the conductive key cover 3 is subjected to external force and moves downward along the reed assembly 4, the second flexure section 44 and the tail section 45 are compressed and bend inward, causing the concave curved section 431 to move inward. The distance between the concave curved section 431 and the vertical section 41 to decrease, and the vertical sections 41 of the two conductive springs 40 to bend and approach each other, allowing the reed assembly 4 to continue to be inserted into the storage cavity 30 and continue to generate a reaction force. Under the pressure of external force, the elastic force generated by each section causes them to tend to expand outward. Once the external force disappears, the conductive key cover 3 will return upward due to the elastic force of the conductive springs 40 themselves, returning to the force balance point, that is, the initial state.

[0039] During use, the conductive key cover 3 is in contact with the skin, and external force pushes the conductive key cover 3 to move on the skin. Facing the facial skin with changes in height, the conductive key cover 3 continuously slides up and down on the reed group 4. During this period, the conductive key cover 3 continuously presses the reed group 4, and the reed group 4 also continuously outputs a reaction force to force the conductive key cover 3 to move up. At the same time, the reed group 4 can continuously flex to cope with lateral external forces, so that the conductive key cover 3 always fits the skin and obtains a comfortable use experience, that is, the user will not feel that the conductive key cover 3 is pressed too hard or too tightly.

[0040] In summary, the present invention connects the reed group and the conductive key cover to form an electrode assembly and installs it on a support, and supplies power through the circuit inside the support, thereby realizing the elastic electrode function of the radio frequency beauty instrument; through the structure of the reed group and the conductive key cover themselves and the connection structure between them, as well as the sealed connection between the reed group and the support, the conductive key cover is fixed in a limited position and elastically expands and contracts during movement. Compared with the coupling connection between the spring and the cylinder, it slides smoothly, there is no gap between the reed group and the support, and it is not easy to get water in. During use, the conductive key cover can slide and expand on the reed group as the face changes, and then fit the face, so that the beauty instrument can achieve better use effect and user experience.
