[0001] This invention relates to the field of negative ion beauty devices, and in particular to a negative ion beauty device that prevents electric arc from creeping outwards. Background Technology

[0002] With the improvement of living standards, modern women are paying more and more attention to their appearance. As a result, all kinds of beauty and skin care devices have appeared on the market. For existing anti-inflammatory and antibacterial skin care devices, the mains power is first converted into low voltage, and then discharged through a high voltage transformer. However, because there is a certain distance between the high voltage transformer and the discharge electrodes, they are not in contact with each other. Therefore, the discharge of the high voltage transformer to the electrodes will generate an electric arc, and the electric arc can easily escape. If the hand is not holding the handle of the beauty and skin care device, the distance between the high voltage transformer and the hand will form an electric arc. Therefore, holding the handle of the beauty device will cause a slight numbness, thus affecting the user experience.

[0030] To make the objectives, technical solutions, and advantages of the present invention clearer and more explicit, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] like Figure 1-7 As shown, this invention discloses a negative ion beauty device with anti-arc creep, comprising a shell 1, a high-voltage transformer 2, a control circuit board 3, and a glass tube 4 for storing inert gas. The control circuit board 3 is installed inside the shell 1. The high-voltage transformer 2 is connected to the control circuit board 3 via wires, and a discharge stud 5 is fixed to the discharge end of the high-voltage transformer 2. The glass tube 4 is inserted into the tail end of the shell 1, and the tail end of the shell 1 is provided with a glass tube insertion hole 10. An electrode copper sleeve 6 is inserted into the glass tube insertion hole 10. The electrode copper sleeve 6 is connected to the discharge stud 5 via bolts 7. The glass tube 4 is inserted into the glass tube insertion hole 10 and nested with the electrode copper sleeve 6. At least one layer of arc protection ring 20 is provided at one end of the high-voltage transformer 2 that fixes the discharge stud 5 to prevent arc creep.

[0032] With the above structure, this invention, by setting an arc protection ring 20 at the discharge end of the high-voltage transformer 2, can intercept the arc that crawls out when the discharge stud 5 discharges, so that there is no numbness when the hand holds the outer shell 1; and because the electrode copper sleeve 6 is connected to the discharge stud 5, the dragging gas in the glass tube 4 can be energized to form a charged inert gas, and negative ions or ozone are generated near the glass tube 4, thereby achieving skin disinfection and sterilization. Since the glass tube 4 is inserted into the electrode copper sleeve 6, the distance between the arc generated by the electrode copper sleeve 6 and the hand is much greater than the distance between the hand and the discharge stud 5, so the hand will not be energized by the arc, and there will be no numbness, thus making the user experience better.

[0033] Preferably, the electrode copper sleeve 6 is also fitted with a protective sleeve 8, which can tighten the glass tube 4 after it is inserted into the electrode copper sleeve 6, thereby achieving fixation.

[0034] Preferably, the glass tube 4 has a pipe-shaped structure and is filled with an inert gas.

[0035] Preferably, the high-voltage transformer 2 includes a coil core 21, sealant 22, and a high-voltage transformer shell 23. The discharge stud 5 is fixed to the center of the arc protection ring 20 of the high-voltage transformer shell 23 by screws 9. The input end of the coil core 21 is connected to the control circuit board 3, and the output end of the coil core 21 is connected to the discharge stud 5. The coil core 21 is encapsulated in the high-voltage transformer shell 23 by sealant 22. Since the coil core 21 of the high-voltage transformer 2 is sealed by sealant potting, the encapsulation effect is better, the leakage prevention performance is better, and the production time of the high-voltage transformer 2 is shortened.

[0036] Preferably, the high-voltage casing 23 includes a head cover 230 and a body 231. The head cover 230 is fixedly connected to one end of the body 231. The arc protection ring 20 is disposed on the head cover 230. The head cover 230 has a positioning groove 100 for installing the discharge stud 5 at its center, and the positioning groove 100 has a screw hole 101 at its center.

[0037] Preferably, the discharge stud 5 is fixedly connected to the head cover 230 by screws 9, so the fixing method of the discharge stud 5 is simple.

[0038] Preferably, the head cover 230 and the shell 231 are separate structures, and the head cover 230 and the shell 231 are fixedly connected by plugging.

[0039] The head cover 230 and the shell 231 of the present invention can also be a separate structure. The head cover 230 and the shell 231 are fixedly connected by plugging. By designing the head cover 230 and the shell 231 as a separate structure, the processing of the high-pressure shell 23 is simplified.

[0040] Preferably, the head cover 230 and the shell body 231 are an integral structure.

[0041] Preferably, the arc protection ring 20 has two layers, namely a first arc protection ring 200 and a second arc protection ring 201. The second protection ring 201 is disposed around the first arc protection ring 200, and the first arc protection ring 200 is disposed around the opening of the positioning groove 100.

[0042] With the above structure, the first arc protection ring 20 can initially intercept the arc, and the second arc protection ring 201 further intercepts the arc that has crossed the first arc protection ring 200, thus ensuring that the arc is fully intercepted. Therefore, when a person holds the outer shell 1 of the beauty and skin care device, the arc will not come into contact with the person's hand, and no weak current sensation will be formed, resulting in a better tactile experience.

[0043] Preferably, the second layer of arc protection ring 201 is provided with multiple notches 202 to prevent the high voltage casing 23 from rotating relative to the handle of the beauty and skin care device during installation; by providing notches, when the encapsulated high voltage package 2 is installed, the discharge stud 5 is fixedly connected to the outer casing 1 and will not rotate, and the notches can be used in conjunction with the locking blocks inside the outer casing 1 to achieve locking.

[0044] Preferably, the head cover 230 is also provided with two locking posts to prevent the coil from rotating. The locking posts are arranged symmetrically. Therefore, when the coil is placed into the shell 231, the coil frame can be well locked and fixed by the locking posts, and will not rotate in reverse, causing the connecting wires outside the coil to cross and break.

[0045] Preferably, the shell body 231 is provided with a corresponding groove for connecting the head cover; therefore, the head cover 230 can be directly inserted into the groove and quickly fixedly connected to the shell body 231, making assembly convenient and simple.

[0046] Preferably, the cross-section of the shell portion 231 is circular, quadrilateral, or polygonal.

[0047] Preferably, the outer casing 1 includes a handle casing 11, a circuit board fixing casing 12, and a sealing end cap 13; the handle casing 11 is snapped to the circuit board fixing casing 12 via an amplification ring 14, and the sealing end cap 13 is fixedly connected to the circuit board fixing casing 12 via screws.

[0048] The present invention uses a circuit board fixing housing 12 to snap together with the handle housing 11, so assembly is convenient. The amplification ring 14 enables the circuit fixing housing 12 to be better locked and clamped to the handle housing 11.

[0049] Preferably, the sealing end cap 13 is provided with a switch mounting hole 130 and a wire hole 131 for installing a switch. The switch mounting hole 130 is equipped with a rotary switch 15, so the control circuit board 3 can be opened and closed by connecting the rotary switch 15 to the control circuit board 3. The wire hole 131 can be connected to the external mains power through a wire.

[0050] Preferably, the circuit board fixing shell 12 is provided with a slot 120 for inserting the control circuit board 3 and a latching block 121 for snap-fit ​​connection with the handle shell 11. There are two slots 120, which are symmetrically arranged on the inner wall of the circuit board fixing shell 12.

[0051] With the above structure, the control circuit board 3 of the present invention can be quickly fixed through the slot 120. The locking block 121 can better achieve a locking connection with the locking groove 110 of the handle shell 11; the locking block 121 is fixed by being screwed into the locking groove 110 by a knob.

[0052] Preferably, one end of the outer wall of the handle housing 11 is provided with a corresponding latching groove 110 for locking, and the inner side wall of the tail end of the handle housing is provided with a positioning piece 111 to prevent the high voltage transformer 2 from rotating when connected to the electrode copper sleeve 6; therefore, when installing the electrode copper sleeve 6 and tightening the bolt 7, it can prevent the bolt 7 from driving the discharge stud 5 to rotate, thereby driving the high voltage to rotate; and prevent the wires between the high voltage transformer 2 and the control circuit board 3 from getting tangled. The surface of the handle housing is also provided with anti-slip stripes, so it is not easy to slip during use.

[0053] like Figure 8As shown, the control circuit board 3 includes terminals J1, J2, J3, and J4, diodes D1 and D2, filter capacitors C1 and C2, a thyristor pulse switch T1, a current-limiting sampling resistor R3, a load resistor R1, and a protection resistor R2. Diode D1 and filter capacitor C1 are connected in series, and diode D2 and filter capacitor C2 are also connected in series. Diode D1 and filter capacitor C1 are connected in series between 220V power lines, and diode D2 and filter capacitor C2 are also connected in series between 220V power lines. The series-connected diode D1 and filter capacitor C1 are then connected to the series-connected diode... The circuit consists of diode D2 and filter capacitor C2; one end of filter capacitor C1 is connected to terminal J3, and the other end of filter capacitor C1 is connected to terminal J1 of the 220V input terminal through load resistor R1 and fuse F1; pin 3 of the thyristor pulse switch T1 is connected to terminal J2 through diode D3, pin 2 of the thyristor pulse switch T1 is connected between diode D2 and filter capacitor C2, pin 2 of the thyristor pulse switch T1 is connected to terminal J2 through current-limiting sampling resistor R3, pin 2 of the thyristor pulse switch T1 is also connected to terminal J4, and diode D3 and current-limiting sampling resistor R3 are also connected to a protection resistor R2. Diodes D1 and D2 are used to perform voltage multiplication and rectification of the mains power, while filter capacitors C1 and C2 perform filtering and voltage multiplication. These four components form a voltage multiplier circuit. The thyristor switch controls whether the high-voltage transformer 2 discharges. The current-limiting sampling resistor R3 limits the current and samples the control pulse signal, which is controlled to open and close by diode D3. The protection resistor R2 protects the potentiometer connected to terminal J2, and the load cell is used to stabilize the AC power.

[0054] This invention features an arc protection ring 20 at the discharge end of the high-voltage transformer 2. This ensures that the high-voltage transformer 2 connects to the discharge electrode copper sleeve 6 via the discharge stud 5, resulting in the closest possible distance between the discharge stud 5 and the electrode copper sleeve 6 (zero-distance contact). Therefore, when a person holds the handle of the beauty and skincare device, the distance between their hand and the discharge stud is much greater than the distance between the discharge stud and the electrode copper sleeve 6, preventing the arc from spreading outwards. The electrode copper sleeve 6 conducts electricity through the inert gas inside the glass tube 4, generating negative ions to achieve anti-inflammatory effects on the skin. Furthermore, even if an arc is generated between the discharge stud 5 and the electrode copper sleeve 6, it will be intercepted by the arc protection ring 20, preventing the arc from spreading. Therefore, there is no slight current sensation when holding the handle, resulting in a better sensory experience.

[0055] The above are merely preferred embodiments of the present invention, and should not be construed as limiting the scope of the present invention. It should be noted that for those skilled in the art, any modifications or equivalent substitutions to the technical solutions of the present invention without creative effort do not depart from the protection scope of the technical solutions of the present invention.
