The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
The implementation mode is as follows:
referring to fig. 1-6, the present invention discloses an isolated arc rf hand tool, which comprises an operating head 1 and a hand tool housing 2, wherein the hand tool housing 2 is a hollow structure with two open ends, the upper end of the operating head 1 is used for contacting with the skin of a user, and the lower end of the operating head 1 is located in the hand tool housing 2. The lower end of the operating head 1 is also provided with a cavity 10, the inner wall of the cavity 10 is connected with a pressure plate 4, and the pressure plate 4 is in threaded sealing connection with the cavity 10. Specifically, an external thread is arranged on the inner wall of the cavity 10, an internal thread meshed with the external thread is arranged on the outer wall of the pressing plate 4, so that the pressing plate 4 is in threaded connection with the operating head 1, and the operating head 1 is in threaded connection with the pressing plate 4, so that the operating head 1 can be replaced later; a sealing ring 42 is arranged between the pressure plate 4 and the lower end of the cavity 10 and used for sealing between the pressure plate 4 and the operating head 1.
On the basis of the structure, the mounting plate 5 is arranged below the pressing plate 4, and the mounting plate 5 is fixed in the hand tool shell 2. Specifically, the mounting plate 5 is provided with a plurality of fasteners 52, the hand tool housing 2 is provided with a plurality of slots 21 corresponding to the fasteners 52 one by one, and the mounting plate 5 is fixed on the hand tool housing 2 by means of the fasteners 52 and the slots 21. In addition, spring mounting groove 51 has been seted up to the upper surface of mounting panel 5, install compression spring 510 in the spring mounting groove 51, just compression spring 510's upper end with clamp plate 4 is connected, the upper surface of mounting panel 5 still is provided with pressure sensor 50, promptly pressure sensor 50 is located between mounting panel 5 and the clamp plate 4.
Of course, the pressure sensor 50 is in signal connection with the main control board of the beauty instrument equipment, when the operator brings the operating head 1 into contact with the skin of the user, the pressure plate 4 can touch the pressure sensor 50 under the action of the compression spring 510, and the pressure sensor 50 feeds back a signal to the main control board of the beauty instrument equipment, so as to conduct and transmit a high-frequency signal to the radio frequency hand tool for work; when an operator separates the operating head 1 from the skin of a user, the pressing plate 4 is disconnected from the pressure sensor 50 under the action of the compression spring 510, the pressure sensor 50 feeds back a signal to a main control panel of the beauty instrument equipment, so that the radio frequency hand set is controlled to stop working, the skin of the user is not scalded due to electric arc generated by improper operation of the operator, namely the radio frequency hand set does not need strong professional operation, and the operation is simpler, more convenient and safer. In addition, at the moment when the operating head 1 is separated from the skin of the user, the operating head 1 still can be in close contact with the skin of the user due to the inertia effect of the compression spring 510, but at this moment, the operating head 1 is disconnected from the pressure sensor 50 due to the reduction of the pressure, so that the generation of electric arcs is avoided, the skin of the human body is prevented from being scalded until the operating head 1 is completely separated from the skin of the human body, and the operation is safer for the user.
Because the lower end of the operating head 1 is positioned in the hand tool shell 2, namely, a gap exists between the outer wall of the lower end of the operating head 1 and the inner wall of the hand tool shell 2. In order to prevent other impurities such as dust from entering the hand tool from the gap during the use of the radio frequency hand tool, thereby causing the blockage or corrosion of the interior of the hand tool. Preferably, a gap between the outer wall of the operating head 1 and the inner wall of the hand tool shell 2 is sealed by a dustproof silica gel sleeve 3. Further, first mounting groove 11 has been seted up to the outer wall circumference of operating head 1, just first mounting groove 11 is located the top of hand utensil shell 2, second mounting groove 20 has been seted up to the outer wall circumference of hand utensil shell 2, the one end of dustproof silica gel cover 3 is inserted first mounting groove 11, the other end of dustproof silica gel cover 3 is inserted second mounting groove 20 to there is the sealed in clearance between the outer wall of the lower extreme of realization operating head 1 and the inner wall of hand utensil shell 2.
Of course, the pressing plate 4 has a gap with the upper end of the cavity 10, the pressing plate 4 is provided with a water inlet pipe 40 and a water outlet pipe 41, the water inlet pipe 40 and the water outlet pipe 41 extend from the lower end of the pressing plate 4 to the lower end direction of the hand tool housing 2, and the water inlet pipe 40 and the water outlet pipe 41 are both communicated with the gap, so that the water from the water inlet pipe 40 moistens the operating head 1 and then flows out from the water outlet pipe 41. That is, it can be understood that the water inlet pipe 40 is communicated with the water outlet end of the beauty treatment apparatus, the water outlet pipe 41 is communicated with the water inlet end of the beauty treatment apparatus, when the hand tool is conducted to work, water enters the gap from the water inlet pipe 40 to moisten the operating head 1, and then comes out from the water outlet pipe 41, thereby realizing the effects of moisturizing massage, skin relaxation, collagen regeneration stimulation and the like of the operating head 1.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
