Description

Technical Field

[0001] This utility model relates to the field of beauty instrument technology, and in particular to a beauty instrument controller circuit, a beauty instrument control line circuit, and a beauty instrument. Background Technology

[0002] With the widespread adoption of Type-C interfaces, many electronic products have begun using them for charging and data transfer. However, devices such as beauty devices often use the same Type-C interface for both the control cable and the charging cable. Since both ends of a Type-C interface can be inserted, users can easily insert the charging cable into the control port, causing the charging current to directly enter the main control circuit. This can easily lead to circuit burnout or damage, thus affecting the normal operation of the device.

[0003] To address this issue, existing solutions typically involve changing the interface type, such as replacing the Type-C interface with a Micro USB interface. However, this design does not align with the growing popularity of Type-C interfaces, while user demand for Micro USB interfaces is gradually declining. Because this design is inconvenient for users' habits, it is difficult to promote widely.

[0004] Therefore, there is an urgent need for a beauty device controller circuit that can solve the problem of incorrect Type-C interface insertion without affecting the user's usage habits. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of existing beauty devices where the control interface is damaged due to incorrect plugging of the charging cable, and to provide a beauty device controller circuit, a beauty device control line circuit, and a beauty device.

[0006] The present invention provides a beauty device controller circuit, including a main control board chip, a connection detection circuit for detecting the connection of the beauty device control line, and a positive and negative insertion detection circuit for detecting the positive and negative insertion of the beauty device control line. The main control chip includes a first signal transceiver port group and a second signal transceiver port group. The first signal transceiver port group is electrically connected to the connection detection circuit, and the second signal transceiver port group is electrically connected to the positive and negative insertion detection circuit.

[0007] In one of the alternative technical solutions, if the first signal transceiver port group is connected to the beauty device control line, the connection detection circuit outputs a high-level signal; If the first signal transceiver port group is not connected to the beauty device control line, the connection detection circuit outputs a low-level signal.

[0008] In one alternative technical solution, the first signal transceiver port group includes a first signal receiving port and a first signal transmitting port, and the connection detection circuit includes a first resistor, a second resistor, and a third resistor. One end of the first resistor is electrically connected to the power supply, and the other end of the first resistor is electrically connected to the first signal receiving port. The output terminal of the first signal transmitting port is electrically connected to one end of the second resistor and the third resistor, respectively, and the other end of the second resistor and the third resistor is grounded.

[0009] In one of the alternative technical solutions, the connection detection circuit further includes a filter capacitor, one end of which is electrically connected to the other end of the second resistor, and the other end of which is grounded.

[0010] In one of the alternative technical solutions, the connection detection circuit further includes a Zener diode, the negative terminal of which is electrically connected to the other end of the second resistor, and the positive terminal of which is grounded.

[0011] In one of the alternative technical solutions, if the second signal transceiver port group is connected to the front side of the beauty device control line, the positive and negative insertion detection circuit outputs a high-level signal; If the second signal transceiver port group is connected to the opposite side of the beauty device control line, the positive / negative insertion detection circuit outputs a low-level signal.

[0012] In one alternative technical solution, the second signal transceiver port group includes a second signal receiving port and a second signal transmitting port, and the positive / negative insertion detection circuit includes a fourth resistor. One end of the fourth resistor is electrically connected to the power supply, and the other end of the fourth resistor is electrically connected to the second signal receiving port, while the second signal transmitting port is grounded.

[0013] The present invention also provides a control line circuit for a beauty device, including a control line chip. The control line chip includes a third signal receiving port, a third signal transmitting port, a fourth signal receiving port, and a fourth signal transmitting port. The third signal receiving port is electrically connected to the third signal transmitting port, and is used to be electrically connected to the connection detection circuit of the beauty device controller circuit as described above. The fourth signal receiving port is electrically connected to the positive / negative insertion detection circuit of the beauty device controller circuit as described above, and the fourth signal transmitting port is grounded.

[0014] The present invention also provides a beauty device, including at least two TYPE-C interfaces, one of which uses a beauty device controller circuit as described above.

[0015] One of the alternative technical solutions also includes the beauty device control line circuit as described above.

[0016] The above technical solution has the following beneficial effects: by electrically connecting the first signal transceiver port group of the main control chip to the connection detection circuit, the connection of the beauty device control line is detected, thus avoiding circuit damage caused by misplugging the charging cable; and by electrically connecting the second signal transceiver port group of the main control chip to the positive and negative insertion detection circuit, the correct insertion of the beauty device control line is detected, thus avoiding circuit damage caused by reverse insertion of the control line, improving safety and enhancing user experience.

Detailed Implementation

[0018] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0019] It is readily understood that, based on the technical solution of this invention, various structural and implementation methods can be interchanged by those skilled in the art without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of the invention.

[0020] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the structures shown in the accompanying drawings. They are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0021] like Figure 1As shown, an embodiment of the present invention provides a beauty device controller circuit 10, including a main control board chip 11, a connection detection circuit 12 for detecting the connection of the beauty device control line 30, and a positive / negative insertion detection circuit 13 for detecting the positive / negative insertion of the beauty device control line 30. The main control chip 11 includes a first signal transceiver port group and a second signal transceiver port group. The first signal transceiver port group is electrically connected to the connection detection circuit 12, and the second signal transceiver port group is electrically connected to the positive / negative insertion detection circuit 13.

[0022] The beauty device controller circuit 10 provided in this embodiment is applied to the TYPE-C interface and mainly includes a main control board chip 11, a connection detection circuit 12, and a positive and negative insertion detection circuit 13.

[0023] The main control board chip 11 uses the existing main control board chip of the beauty device controller, so its specific structure and working principle will not be described in detail here.

[0024] The connection detection circuit 12 is used to detect whether the beauty device control line 30, which matches the interface of the beauty device controller, is connected. If the first signal transceiver port group is connected, a high voltage is generated at the output terminal LINE1 of the connection detection circuit 12; otherwise (e.g., if the first signal transceiver port group is connected, a high voltage is generated at the output terminal LINE1 of the connection detection circuit 12); otherwise (e.g., if the first signal transceiver port group is connected, a high voltage is generated at the output terminal LINE1 of the connection detection circuit 12). Figure 2 When the charging cable 20 shown is inserted into the interface of the beauty device controller, the first signal transceiver port group is not connected, and the output terminal LINE1 of the connection detection circuit 12 generates a low voltage, thereby avoiding circuit damage caused by mis-insertion of the charging cable and improving safety.

[0025] The positive and negative insertion detection circuit 13 is used to detect whether the positive and negative sides of the beauty instrument control line 30 are inserted correctly. If the second signal transceiver port group is connected, the output terminal LINE2 of the positive and negative insertion detection circuit 13 generates a high voltage; otherwise, the second signal transceiver port group is not connected, and the output terminal LINE2 of the positive and negative insertion detection circuit 13 generates a low voltage, thereby avoiding circuit damage caused by the control line being inserted in the wrong direction and further improving safety.

[0026] It should be noted that the beauty device can be set to only output normally when both the connection detection circuit 12 and the forward and reverse insertion detection circuit 13 output high voltage, further improving safety.

[0027] In this embodiment, the beauty device controller circuit electrically connects the first signal transceiver port group of the main control chip to the connection detection circuit to detect the connection of the beauty device control line, thereby preventing circuit damage caused by incorrect insertion of the charging cable; and electrically connects the second signal transceiver port group of the main control chip to the positive and negative insertion detection circuit to detect whether the beauty device control line is inserted correctly in either direction, thereby preventing circuit damage caused by reverse insertion of the control line, improving safety and enhancing user experience.

[0028] In one embodiment, to facilitate the detection of the connection of the beauty device control line, if the first signal transceiver port group is connected to the beauty device control line 30, the connection detection circuit 12 outputs a high-level signal. If the first signal transceiver port group is not connected to the beauty device control line 30, the connection detection circuit 12 outputs a low-level signal.

[0029] In one embodiment, the first signal transceiver port group includes a first signal receiving port A11 and a first signal transmitting port A10, and the connection detection circuit 12 includes a first resistor R45, a second resistor R61, and a third resistor R62. One end of the first resistor R45 is electrically connected to the power supply, and the other end of the first resistor R45 is electrically connected to the first signal receiving port A11. The output terminal of the first signal transmission port A10 is electrically connected to one end of the second resistor R61 and the third resistor R62, respectively, and the other end of the second resistor R61 and the third resistor R62 is grounded.

[0030] The connection detection circuit 12 includes a first resistor R45, a second resistor R61 and a third resistor R62. The first resistor R45 is electrically connected to a 3V3 power supply, and the second resistor R61 and the third resistor R62 are connected in parallel.

[0031] During testing, when the first signal receiving port A11 and the first signal transmitting port A10 are connected to a wire, the detection circuit 12 determines whether the connected wire is a beauty device control wire (e.g., ...). Figure 2 If the charging cable 20 shown is not connected, the 3V3 power supply enters the first signal receiving port A11 through the first resistor R45, then exits from the first signal transmitting port A10, and is grounded through the second resistor R61. At this time, the output terminal LINE1 of the connection detection circuit 11 is 0. If the connection is to the beauty device control cable, the 3V3 power supply enters the first signal receiving port A11 through the first resistor R45, then exits from the first signal transmitting port A10, and is output through the third resistor R62. At this time, the output terminal LINE1 of the connection detection circuit 11 is 1, thereby detecting whether the connected cable is a beauty device control cable.

[0032] In one embodiment, the connection detection circuit 12 further includes a filter capacitor C29, one end of which is electrically connected to the other end of the second resistor R61, and the other end of which is grounded.

[0033] The connection detection circuit 12 also includes a filter capacitor C29. The filter capacitor C29 is used to absorb electric sparks that occur during insertion and removal or when there is static electricity, to prevent voltage fluctuations, and to make the connection detection circuit 12 smooth and not affect the judgment.

[0034] In one embodiment, the connection detection circuit 12 further includes a Zener diode D19, the negative terminal of which is electrically connected to the other end of the second resistor R61, and the positive terminal of which is grounded.

[0035] The connection detection circuit 12 also includes a Zener diode D19, which is connected in parallel with the filter capacitor C29. The Zener diode D19 is used to prevent electrical sparks during insertion and removal from burning down downstream devices, thereby further improving safety.

[0036] In one embodiment, in order to facilitate the detection of whether the front or back of the beauty device control line is inserted correctly, if the second signal transceiver port group is connected to the front of the beauty device control line 30, the front or back insertion detection circuit 13 outputs a high-level signal. If the second signal transceiver port group is connected to the opposite side of the beauty device control line 30, the positive / negative insertion detection circuit 13 outputs a low-level signal.

[0037] In one embodiment, the second signal transceiver port group includes a second signal receiving port B11 and a second signal transmitting port B10, and the positive / negative insertion detection circuit 13 includes a fourth resistor R39. One end of the fourth resistor R39 is electrically connected to the power supply, and the other end of the fourth resistor R39 is electrically connected to the second signal receiving port B11. The second signal transmitting port B10 is grounded.

[0038] During testing, if the beauty device control line 30 is inserted on the reverse side, that is, the second signal receiving port B11 and the second signal transmitting port B10 are connected as follows: Figure 3 The third signal receiving port A′11 and the third signal transmitting port A′10 of the beauty device control line 30 shown are connected to ground, so the output terminal LINE2 of the positive and negative insertion detection circuit 13 is 0. If the beauty device control line 30 is inserted in the front, that is, the second signal receiving port B11 and the second signal transmitting port B10 are connected to the fourth signal receiving port B′11 and the fourth signal transmitting port B′10 of the beauty device control line 30, the 3V3 power supply enters the second signal receiving port B11 through the fourth resistor R39. At this time, the output terminal LINE2 of the positive and negative insertion detection circuit 13 is 1, thereby detecting whether the positive and negative sides of the beauty device control line are inserted correctly.

[0039] In one embodiment, the beauty device controller circuit also includes an alert, which is electrically connected to the connection detection circuit 12 and the positive / negative insertion detection circuit 13 respectively. The alert is triggered when the connection detection circuit 12 and / or the positive / negative insertion detection circuit 13 outputs a low level, thereby promptly reminding the user and further improving safety.

[0040] Preferably, the alert can be an audible and visual alarm.

[0041] like Figure 3 As shown, an embodiment of the present invention provides a beauty instrument control line circuit 20, which includes a control line chip 21. The control line chip 21 includes a third signal receiving port A′11, a third signal transmitting port A′10, a fourth signal receiving port B′11, and a fourth signal transmitting port B′10. The third signal receiving port A′11 is electrically connected to the third signal transmitting port A′10 and is used to electrically connect to the connection detection circuit 11 of the beauty instrument controller circuit 10 as described above. The fourth signal receiving port B′11 is electrically connected to the positive and negative insertion detection circuit 13 of the beauty instrument controller circuit 10 as described above, and the fourth signal transmitting port B′10 is grounded.

[0042] In this embodiment, the beauty device control line circuit forms a connection by electrically connecting the third signal receiving port and the third signal transmitting port, which are electrically connected to the connection detection circuit of the beauty device controller circuit. The fourth signal receiving port is electrically connected to the positive and negative insertion detection circuit of the beauty device controller circuit, and the fourth signal transmitting port is grounded. This ensures that the beauty device control line matches the beauty device control interface, avoids circuit damage caused by misinsertion of the charging cable and / or reverse insertion of the control line, improves safety, and enhances the user experience.

[0043] The present invention also provides a beauty device, including at least two TYPE-C interfaces, one of which uses a beauty device controller circuit as described above.

[0044] Preferably, one of the TYPE-C interfaces uses a 24-pin connector for control and the other uses a 12-pin connector for charging.

[0045] In this embodiment of the beauty device, one of the TYPE-C interfaces is integrated into the beauty device controller circuit, which avoids damage to the circuit caused by accidental plugging in of the charging cable, thereby improving safety and enhancing the user experience.

[0046] In one embodiment, the device also includes the beauty device control line circuit as described above, which ensures that the beauty device control line matches the beauty device control interface, avoids damage to the circuit caused by misplugging the charging cable and / or reversing the control line, improves safety, and enhances the user experience.

[0047] The above description is merely the principle and preferred embodiment of this utility model. It should be noted that, for those skilled in the art, several other modifications can be made based on the principle of this utility model, and these modifications should also be considered within the protection scope of this utility model.
