[0043] Current-limiting resistor 4. Detailed implementation manners

[0044] The embodiments of the utility model will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the utility model and should not be construed as limiting the utility model.

[0045] The filter of the embodiment of the utility model will be described below with reference to the accompanying drawings.

[0046] As Figures 1 to 3 shown, the filter of the embodiment of the present utility model includes a first circuit 1, a second circuit 2 and a control component 3. Among them,

[0047] The first circuit 1 has at least the following two configurations:

[0048] Configuration 1: The first circuit 1 includes at least one adjustable capacitor 11. For example, the first circuit 1 includes one adjustable capacitor 11, and the capacitance connected in the first circuit 1 is changed by adjusting the adjustable capacitor 11. Alternatively, the first circuit 1 includes multiple adjustable capacitors 11, and the capacitance connected in the first circuit 1 is changed by adjusting one or more of the adjustable capacitors 11. When the multiple adjustable capacitors 11 are connected in parallel with each other, the capacitance connected in the first circuit 1 is equal to the sum of the capacitances of the individual adjustable capacitors 11. When the multiple adjustable capacitors 11 are connected in series in sequence, the capacitance connected in the first circuit 1 is equal to the reciprocal of the sum of the reciprocals of the capacitances of the individual adjustable capacitors 11.

[0049] Configuration 2: The first circuit 1 includes a first capacitor 12, multiple second capacitors 13, and multiple capacitance switches 14 corresponding to the multiple second capacitors 13 one by one. The first capacitor 12 is connected in parallel with all the second capacitors 13, the multiple second capacitors 13 are connected in parallel with each other, and the capacitance switch 14 is connected in series with the corresponding second capacitor 13 to enable the capacitance switch 14 to control the connected or disconnected state of the corresponding second capacitor 13. In this configuration, the capacitance connected in the first circuit 1 is equal to the sum of the capacitance of the first capacitor 12 and the capacitances of the second capacitors 13 in the connected state.

[0050] The second circuit 2 is connected in series with the first circuit 1, and the second circuit 2 has at least the following two configurations:

[0051] Configuration 1: The second circuit 2 includes at least one adjustable inductor 21. For example, the second circuit 2 includes one adjustable inductor 21, and the inductance connected in the second circuit 2 is changed by adjusting the adjustable inductor 21. Alternatively, the second circuit 2 includes multiple adjustable inductors 21 connected in series in sequence, and the inductance connected in the second circuit 2 is changed by adjusting one or more of the adjustable inductors 21. The inductance connected in the second circuit 2 is equal to the sum of the inductances of the individual adjustable inductors 21.

[0052] Configuration 2: The second circuit 2 includes a first inductor 22, multiple second inductors 23, and multiple inductance switches 24 corresponding to the multiple second inductors 23 one by one. The multiple second inductors 23 are connected in series in sequence after the first inductor 22 to form a series inductance path, and the inductance switch 24 is connected in parallel with the corresponding second inductor 23. The inductance switch 24 is used to control whether the corresponding second inductor 23 is connected to the series inductance path. When the inductance switch 24 is closed, the corresponding second inductor 23 is connected to the series inductance path. When the inductance switch 24 is open, the corresponding second inductor 23 is disconnected from the series inductance path. In this configuration, the inductance connected in the second circuit 2 is equal to the sum of the inductance of the first inductor 22 and the inductances of the second inductors 23 connected to the series inductance path.

[0053] The control component 3 is used to control the access capacitance of the first circuit 1 and / or the access inductance of the second circuit 2 to change the center frequency. In other words, the control component 3 can independently control the access capacitance of the first circuit 1 or the access inductance of the second circuit 2 to change the center frequency of the filter, and the control component 3 can also control the first circuit 1 and the second circuit 2 simultaneously to change the center frequency of the filter.

[0054] It should be noted that the first circuit 1 and the second circuit 2 form an LC series circuit. According to the center frequency calculation formula of the LC circuit where f is the center frequency, L is the access inductance of the second circuit 2, and C is the access capacitance of the first circuit 1. Changing the access capacitance of the first circuit 1 and / or the access inductance of the second circuit 2 can change the center frequency of the filter, thereby attenuating the radio frequency current outside the center frequency and obtaining the radio frequency current of the required frequency; the above-mentioned access capacitance refers to the capacitance that can be connected to the circuit and effectively process or store, and the above-mentioned access inductance refers to the inductance that can be connected to the circuit and effectively process or store.

[0055] When the first circuit 1 uses Configuration 1, the control component 3 controls the access capacitance of the first circuit 1 by controlling the access capacitance of the adjustable capacitor 11; when the first circuit 1 uses Configuration 2, the control component 3 controls the access or disconnection state of the second capacitor 13 by controlling the capacitance switch 14, thereby controlling the access capacitance of the first circuit 1; when the second circuit 2 uses Configuration 1, the control component 3 controls the access inductance of the second circuit 2 by controlling the access inductance of the adjustable inductor 21; when the second circuit 2 uses Configuration 2, the control component 3 controls whether the second inductor 23 is connected to the series inductance path by controlling the inductance switch 24 to control the access inductance of the second circuit 2.

[0056] The filter according to the embodiment of the present invention changes the center frequency by changing the access capacitance of the first circuit 1 and / or the access inductance of the second circuit 2, so that the radio frequency beauty instrument connected to the filter can output radio frequency currents of different frequencies to heat tissues at different depths, improving the treatment effect.

[0057] Optionally, the filter according to the embodiment of the present invention further includes a housing (not shown), and the first circuit 1, the second circuit 2, and the control component 3 are all connected inside the housing, and the housing is used to protect the first circuit 1, the second circuit 2, the control component 3, and other components of the filter.

[0058] Optionally, the filter according to the embodiment of the present invention further includes a current limiting resistor 4, and the current limiting resistor 4, the first circuit 1, and the second circuit 2 are connected in series in sequence.

[0059] It can be understood that the current-limiting resistor 4 limits the magnitude of the current passing through the circuit through its resistance characteristics, thereby protecting the capacitor and inductor components in the circuit from the impact of excessive current. The series-connected current-limiting resistor 4 also participates in the voltage distribution together with the inductor and capacitor, enabling the circuit to operate in a stable working state and reducing the risk of circuit failure or damage. Moreover, the current-limiting resistor 4 can also suppress the noise and interference signals in the circuit, improving the stability and reliability of the oscillation circuit.

[0060] In some embodiments, the control component 3 includes a control chip, which can be divided into the following two cases according to the selected configurations of the first circuit 1 and the second circuit 2:

[0061] When the first circuit 1 selects configuration one and / or the second circuit 2 selects configuration one, the access capacitance of the first circuit 1 is determined by the access capacitance of the adjustable capacitor 11, and the inductance of the second circuit 2 is controlled by the access inductance of the adjustable inductor 21. The control chip is electrically connected to the adjustable capacitor 11 and / or the adjustable inductor 21, so that the control chip can control the access capacitance of the adjustable capacitor 11 to change the access capacitance of the first circuit 1, and / or the control chip can control the access inductance of the adjustable inductor 21 to change the access inductance of the second circuit 2. The method of controlling the adjustable capacitor 11 and / or the adjustable inductor 21 by the control chip is a conventional setting in the art and will not be elaborated here.

[0062] When the first circuit 1 selects configuration two and / or the second circuit 2 selects configuration two, the access capacitance of the first circuit 1 is determined by the capacitance of the first capacitor 12 and the capacitance of the second capacitor 13 connected to the circuit. The capacitance switch 14 and / or the inductance switch 24 are relays. The control chip is electrically connected to the relays so that the control chip controls the on / off of the capacitance switch 14 and / or the inductance switch 24. The control chip controls the second capacitor 13 connected to the circuit by controlling the on / off of the capacitance switch 14 to change the access capacitance of the first circuit 1, and / or the control chip controls the second inductor 23 connected to the series inductance path by controlling the on / off of the inductance switch 24 to change the access inductance of the second circuit 2. The method of controlling the on / off of the relays by the control chip is a conventional setting in the art and will not be elaborated here.

[0063] As Figures 4 to 7 shown, in some embodiments, the control component 3 further includes a shielding cover 31 and a driving member (not shown). The shielding cover 31 covers the first circuit 1 and the second circuit 2 to reduce the influence of external electromagnetic waves on the first circuit 1 and the second circuit 2 and reduce the radiation of the internally generated electromagnetic waves outward. The shielding cover 31 is provided with multiple rows of control parts 311, and the multiple rows of control parts 311 are arranged on the shielding cover 31 along the first direction (such as Figure 4When multiple rows of control units 311 are provided, they are preferably arranged in sequence from high to low or from low to high so that the center frequency of the filter is arranged. Each row of control units 311 includes at least one first control unit 3111 and / or at least one second control unit 3112. For example, the first row of control units 311 includes one first control unit 3111 and one second control unit 3112, the second row of control units 311 includes two first control units 3111, and the third row of control units 311 includes two second control units 3112.

[0064] When the first control unit 3111 is close to the capacitor switch 14 or the inductor switch 24, the capacitor switch 14 or the inductor switch 24 is closed, and when the second control unit 3112 is close to the capacitor switch 14 or the inductor switch 24, the capacitor switch 14 or the inductor switch 24 is disconnected. The first control unit 3111 can control the capacitor switch 14 and the inductor switch 24 to be closed by mechanical contacts, electromagnetic induction or other non-contact control technologies. Similarly, the second control unit 3112 may not be set or may adopt a control method opposite to that of the first control unit 3111 to control the capacitor. The switch 14 or the inductor switch 24 is disconnected. For example, a protrusion is provided at the first control part 3111, and no protrusion is provided or a groove is provided at the second control part 3112. When the first control part 3111 is close to the capacitive switch 14 or the inductor switch 24, the protrusion presses down the buttons of the capacitive switch 14 and the inductor switch 24 to close the capacitive switch 14 or the inductor switch 24. When the second control part 3112 is close to the capacitive switch 14 or the inductor switch 24, the buttons of the capacitive switch 14 and the inductor switch 24 rebound to disconnect the capacitive switch 14 or the inductor switch 24.

[0065] The driving member is connected to the shielding cover 31 by transmission, and the driving member is used to drive the shielding cover 31 to move along the first direction. It can be understood that the driving member can be a motor, a telescopic rod, a cylinder or other power source, and the driving member is connected to the shielding cover 31 by transmission means such as a gear rack, a worm gear, a connecting rod or other transmission methods.

[0066] Preferably, in each row of control units 311, the sum of the number of first control units 3111 and the number of second control units 3112 is equal to the sum of the number of capacitor switches 14 and the number of inductor switches 24, so that one control unit 311 controls one capacitor switch 14 or one inductor switch 24, ensuring the correspondence between the control unit 311 and the capacitor switch 14 and the inductor switch 24.

[0067] It should be noted that the electronic control method (control chip) and the mechanical control method (shielding cover 31 and driving member) of the control component 3 can be used separately or together:

[0068] 1. When the control chip and the shielding cover 31 are used in combination, and both the control chip and the shielding cover 31 correspond to the capacitive switch 14, the capacitive switch 14 is closed. When neither the control chip nor the shielding cover 31 corresponds to the capacitive switch 14 or when only one of the control chip and the shielding cover 31 corresponds to the capacitive switch 14, the capacitive switch 14 is opened. The control of the control chip and the shielding cover 31 is the same in principle. This method improves the safety of the filter;

[0069] 2. When the control chip and the shielding cover 31 are used in combination, and when only one of the control chip and the shielding cover 31 corresponds to the capacitive switch 14, the capacitive switch 14 is closed. When neither the control chip nor the shielding cover 31 corresponds to the capacitive switch 14, the capacitive switch 14 is opened. This method enables the control chip and the shielding cover 31 to be used as backups for each other.

[0070] As Figures 4 to 6 shown, in some embodiments, the numbers of the first control part 3111 and the second control part 3112 of each row of control parts 311 are different, and / or the arrangement manners of the first control part 3111 and the second control part 3112 of each row of control parts 311 are different.

[0071] It can be understood that according to the number and position of the capacitive switch 14 or the inductive switch 24, and the on / off state of the capacitive switch 14 or the inductive switch 24, the numbers and arrangement manners of the first control part 3111 and the second control part 3112 are correspondingly set. For example, the first row of control parts 311 is provided with one first control part 3111 and two second control parts 3112, and the first row of control parts 311 is arranged in sequence in the manner of the first control part 3111 - the second control part 3112 - the second control part 3112. The second row of control parts 311 is provided with two first control parts 3111 and one second control part 3112, and the second row of control parts 311 is arranged in the manner of the first control part 3111 - the second control part 3112 - the first control part 3111.

[0072] As Figures 4 to 6As shown, in some embodiments, the control component 3 further includes at least one of a first control member 32, a second control member, and a third control member. Among them, there are multiple first control members 32, and the multiple first control members 32 correspond to the multiple first control parts 3111 one by one. The first control member 32 is connected to the corresponding first control part 3111; there are multiple second control members, and the multiple second control members correspond to the multiple second control parts 3112 one by one. The second control member is connected to the corresponding second control part 3112; there is at least one third control member, and the third control member is connected to the shielding cover 31. One third control member is drivingly connected to the adjustable inductor 21 to enable one third control member to control the access inductance of the adjustable inductor 21, and / or another third control member is drivingly connected to the adjustable capacitor 11 to enable another third control member to control the access capacitance of the adjustable capacitor 11.

[0073] As Figures 4 to 6 shown, in some specific embodiments, the first control member 32 at least includes the following configurations:

[0074] As Figure 4 shown, Configuration 1, the on / off of the capacitance switch 14 or the inductance switch 24 is controlled by the light intensity (for example, the capacitance switch 14 or the inductance switch 24 is a light-controlled switch). The control component 3 further includes a light source. Both the first circuit 1 and the second circuit 2 are located on one side of the shielding cover 31, and the light source is located on the other side of the shielding cover 31. A through hole 33 is provided on the first control part 3111 of the shielding cover 31. The first control member 32 includes a light-transmitting member 321, and the light-transmitting member 321 is connected to the shielding cover 31 and seals the through hole 33. It can be understood that when the first control part 3111 is close to the capacitance switch 14 or the inductance switch 24, the light of the light source irradiates the capacitance switch 14 or the inductance switch 24 through the light-transmitting member 321. After the capacitance switch 14 or the inductance switch 24 senses that the light intensity reaches or exceeds the preset value, it remains closed. Since there is no light-transmitting member 321 or a light-shielding member is provided at the second control part 3112, the capacitance switch 14 or the inductance switch 24 at the second control part 3112 remains open due to the light intensity being lower than the preset value.

[0075] As Figure 5As shown in Configuration 2, the on / off state of the capacitive switch 14 or the inductive switch 24 is controlled by the magnetic field intensity (for example, the capacitive switch 14 or the inductive switch 24 is a Hall effect switch, or an armature is provided on the button of the capacitive switch 14 or the inductive switch 24). The first control member 32 includes a magnetic member 322 and a magnetic shielding member 323. The magnetic member 322 is connected to the shielding cover 31. The magnetic member 322 is located between the shielding cover 31 and the first circuit 1, or the magnetic member 322 is located between the shielding cover 31 and the second circuit 2. The magnetic shielding member 323 is sleeved on the magnetic member 322 to reduce the influence of the magnetic member 322 on the components at other positions. It can be understood that when the first control part 3111 is close to the capacitive switch 14 or the inductive switch 24, the magnetic member 322 increases the magnetic field intensity at this place. After the capacitive switch 14 or the inductive switch 24 senses that the magnetic field intensity reaches or exceeds the preset value, it remains closed. Since no magnetic member 322 is provided or a magnetic shielding member 323 is provided at the capacitive switch 14 or the inductive switch 24 at the second control part 3112, the magnetic field intensity sensed by the capacitive switch 14 or the inductive switch 24 at the second control part 3112 is lower than the preset value and remains open.

[0076] As Figure 6 shown in Configuration 3, the on / off state of the capacitive switch 14 or the inductive switch 24 is controlled by pressing. The first control member 32 includes a pushing member 324. The pushing member 324 has a first inclined surface (such as Figure 6 the inclined surface located on the left as shown) and a second inclined surface (such as Figure 6 the inclined surface located on the right as shown) in the first direction. The capacitive switch 14 or the inductive switch 24 has a first side and a second side in the first direction. When the pushing member 324 moves from the first side to the second side of the capacitive switch 14 or the inductive switch 24, the first inclined surface abuts against the triggering part (such as a button, a rocker, a toggle) of the capacitive switch 14 or the inductive switch 24 and closes the capacitive switch 14 or the inductive switch 24. When the pushing member 324 moves from the second side to the first side of the capacitive switch 14 or the inductive switch 24, the second inclined surface abuts against the triggering part of the capacitive switch 14 or the inductive switch 24 and closes the capacitive switch 14 or the inductive switch 24. When the pushing member 324 is separated from the capacitive switch 14 or the inductive switch 24, the triggering part resets to open the capacitive switch 14 or the inductive switch 24.

[0077] In some specific embodiments, the setting of the third control member includes at least the following configurations:

[0078] Configuration 1: For the rotatable adjustable capacitor 11 and the adjustable inductor 21, the third control member includes a rack (not shown) and a gear (not shown). The rack is connected to the shielding cover 31. The gear is sleeved on the knob of the adjustable capacitor 11 or the adjustable inductor 21, and the gear meshes with the rack. By adjusting the transmission ratio between the gear and the rack, the shielding cover 31 can be drivingly connected to the adjustable capacitor 11 or the adjustable inductor 21 at a set transmission ratio. When the shielding cover 31 moves, the shielding cover 31 drives the rack to move, causing the rack to drive the meshing gear to rotate, and the gear drives the knob to rotate to change the capacitance of the adjustable capacitor 11 or the inductance of the adjustable inductor 21.

[0079] Configuration 2: For the slidable adjustable capacitor 11 or the adjustable inductor 21, the third control member includes a connecting member. One end of the connecting member is connected to the shielding cover 31, and the other end of the connecting member is connected to the adjustable inductor 21.

[0080] In one example, the connecting member includes a first rack, a first gear, a second gear, and a second rack. The first rack is connected to the shielding cover 31. The first gear is rotatably connected to the housing and meshes with the first rack. The second gear is coaxially connected to the first gear. The second rack meshes with the second gear. The second rack is connected to the sliding electrode plate of the adjustable capacitor 11. By adjusting the transmission ratio between the first gear and the first rack and the transmission ratio between the second gear and the second rack, the transmission ratio between the shielding cover 31 and the sliding electrode plate of the adjustable capacitor 11 can be adjusted. Alternatively, the second rack is connected to the iron core or the sliding switch of the adjustable inductor 21. By adjusting the transmission ratio between the first gear and the first rack and the transmission ratio between the second gear and the second rack, the transmission ratio between the shielding cover 31 and the iron core or the sliding switch of the adjustable inductor 21 can be adjusted.

[0081] In another example, the connecting member includes a third rack, a third gear, a lead screw, and a nut. The third rack is connected to the shielding cover 31. The third gear is rotatably connected to the housing. The lead screw is coaxially connected to the gear. The nut is threadedly connected to the lead screw and is connected to the sliding electrode plate of the adjustable capacitor 11. By adjusting the transmission ratio between the third gear and the third rack and the transmission ratio between the lead screw and the nut, the transmission ratio between the shielding cover 31 and the sliding electrode plate of the adjustable capacitor 11 can be adjusted. Alternatively, the nut is connected to the iron core or the sliding switch of the adjustable inductor 21. By adjusting the transmission ratio between the third gear and the third rack and the transmission ratio between the lead screw and the nut, the transmission ratio between the shielding cover 31 and the iron core or the sliding switch of the adjustable inductor 21 can be adjusted.

[0082] It should be noted that when the first circuit 1 uses configuration two (the second capacitor 13 and the capacitor switch 14) and the second circuit 2 uses configuration one (the adjustable inductor 21), by setting the transmission ratio between the shielding cover 31 and the adjustable inductor 21 and the distance between the two adjacent control parts 311, the access capacitance of the first circuit 1 and the access inductance of the second circuit 2 are set values ​​and correspond to each other; similarly, when the first circuit 1 uses configuration one (the adjustable capacitor 11) and the second circuit 2 uses configuration two (the second inductor 23 and the inductor switch 24), by setting the transmission ratio between the shielding cover 31 and the adjustable capacitor 11 and the distance between the two adjacent control parts 311, the access capacitance of the first circuit 1 and the access inductance of the second circuit 2 are set values ​​and correspond to each other.

[0083] like Figure 1 and Figure 2 As shown, in some specific embodiments, the capacitive switch 14 includes a housing (not shown), a first contact 141, a second contact 142, a first conductive member 143, an insulating member (not shown) and an elastic member (not shown), wherein the first contact 141 is connected to the first end (such as the first capacitor 12) of the first capacitor 12. Figure 1 The second contact 142 is electrically connected to the first end of the second capacitor 13 (as shown in FIG. Figure 1 The first conductive member 143 is connected to the housing and extends along the second direction (such as Figure 1 The insulating member 140 is movable in an upper and lower direction (as shown in the figure), and the second direction is orthogonal to the first direction. The insulating member is connected to the shell and is movable on the shell along the second direction so that the insulating member has a closed position and an open position. The insulating member is transmission-connected to the first conductive member 143. In the closed position, the insulating member drives the first conductive member 143 to contact the first contact 141 and the second contact 142 respectively. In the open position, the insulating member drives the first conductive member 143 to separate from at least one of the first contact 141 and the second contact 142. One end of the elastic member abuts against the insulating member, and the other end of the elastic member abuts against the shell. The elastic member is used to give a thrust to the insulating member to move from the open position to the closed position, or the elastic member is used to give a thrust to the insulating member to move from the closed position to the open position.

[0084] It should be noted that when the elastic member is used to apply a thrust force for moving the insulating member from the closed position to the open position, the capacitive switch 14 is a normally open switch. At this time, a first pushing block (serving as the first control member 32) is provided at the first control portion 3111, and a relief groove is provided at the second control portion 3112. When the first control portion 3111 approaches the capacitive switch 14, the first pushing block abuts against the insulating member and pushes the insulating member from the open position to the closed position, and the second capacitor 13 corresponding to the capacitive switch 14 is in an access state; when the second control portion 3112 approaches the capacitive switch 14, one end of the insulating member close to the shielding cover 31 enters the relief groove under the thrust of the elastic member, so that the insulating member is kept in the open position, and the second capacitor 13 corresponding to the capacitive switch 14 remains in an open state.

[0085] When the elastic member is used to apply a thrust force for moving the insulating member from the open position to the closed position, the capacitive switch 14 is a normally closed switch. At this time, a relief groove is provided at the first control portion 3111, and a second pushing block (serving as the second control portion 3112) is provided at the second control portion 3112. When the first control portion 3111 approaches the capacitive switch 14, one end of the insulating member close to the shielding cover 31 enters the relief groove under the thrust of the elastic member, so that the insulating member is kept in the open position, and the second capacitor 13 corresponding to the capacitive switch 14 remains in an open state; when the second control portion 3112 approaches the capacitive switch 14, the second pushing block abuts against the insulating member and pushes the insulating member from the open position to the closed position, and the second capacitor 13 corresponding to the capacitive switch 14 is in an access state

[0086] As Figure 1 and Figure 2 shown, further, the capacitive switch 14 further includes a third contact 144, a fourth contact 145, and a second conductive member 146. The third contact 144 is electrically connected to the second end of the second capacitor 13 (such as Figure 1 the lower end shown), the fourth contact 145 is electrically connected to the second end of the first contact 141 (such as Figure 1 the lower end shown), the second conductive member 146 is connected to the housing and is movable along the second direction on the housing, the second conductive member 146 is in transmission connection with the insulating member. In the closed position, the insulating member drives the second conductive member 146 to contact the third contact 144 and the fourth contact 145 respectively. In the open position, the insulating member drives the second conductive member 146 to separate from at least one of the third contact 144 and the fourth contact 145.

[0087] It should be noted that, through the arrangement of the first conductive member 143 and the second conductive member 146, both ends of the second capacitor 13 are controlled by the capacitance switch 14, which can ensure that the access or disconnection of the second capacitor 13 can be completely and quickly controlled when needed, reducing the parasitic capacitance, inductance and other effects of other components or connecting wires in the circuit, resulting in the access state of the second capacitor 13 not being fully controlled and the short-circuit risk caused by improper circuit design or faults. Moreover, the access and disconnection timing of the capacitor can be controlled more precisely, thereby improving the stability and reliability of the circuit, and facilitating fault troubleshooting and repair without worrying about further damage to the circuit due to improper operation.
