Description

Technical Field

[0001] This application relates to the field of beauty equipment technology, and in particular to a beauty device. Background Technology

[0002] As people's living standards improve, they are paying more and more attention to skin care, and the number of beauty devices on the market is also increasing. Currently, most beauty devices typically consist of three main parts: the housing, the driving mechanism, and the treatment unit (such as a hydrating gel or serum gel). Usually, when the beauty device is turned off, the treatment unit retracts into the housing to prevent damage. When the beauty device is activated, the driving mechanism first moves the treatment unit to its working position (either the position corresponding to the current mode or the position set by the user), and then the treatment unit acts on the skin for skincare.

[0003] To enable precise movement of the treatment area to the working position, existing beauty devices typically employ stepper motors, which can control displacement with high precision, as the power source for the drive mechanism. This allows for accurate control of the treatment area's movement distance, ensuring that the treatment area can be precisely driven to the working position. However, the use of expensive stepper motors in these beauty device solutions leads to excessively high costs, reducing the device's market competitiveness. Utility Model Content

[0004] The main purpose of this application is to provide a beauty device that aims to reduce the cost of beauty devices and enhance market competitiveness.

[0006] The nursing unit is movably disposed on the housing, and the drive device is connected to the nursing unit for driving the nursing unit to move relative to the housing; the controller is communicatively connected to the detection device and the drive device.

[0007] The detection device includes a detection circuit and a conductor. The detection circuit has a first detection end that is in active contact with the conductor. The position of the first detection end in contact with the conductor changes with the movement of the nursing part. The detection circuit outputs a corresponding electrical signal to the controller according to the position of the first detection end in contact with the conductor.

[0008] In some embodiments, the drive device is used to drive the nursing part to reciprocate relative to the housing in a first direction; and / or, the drive device is used to drive the nursing part to rotate relative to the housing.

[0012] In some embodiments, the conductor portion includes a resistance strip extending along the movement direction of the care portion, and the detection circuit further has a second detection terminal electrically connected to the resistance strip, wherein the first detection terminal movably contacts the resistance strip;

[0013] The resistance value between the first detection terminal and the second detection terminal changes with the movement of the nursing unit. The detection circuit outputs a corresponding electrical signal to the controller based on the resistance value between the first detection terminal and the second detection terminal.

[0014] In some embodiments, the position where the second detection end is electrically connected to the resistance strip is fixed, and when the nursing part moves, the first detection end moves along the resistance strip;

[0015] Alternatively, the second detection end is in active contact with the resistance strip, and when the nursing part moves, the first detection end and the second detection end move synchronously along the resistance strip, and the cross-sectional area of ​​the resistance strip gradually increases along its length.

[0016] In some embodiments, the detection circuit further includes a first load and a first power supply, the first detection terminal is electrically connected to the first power supply via the first load, the second detection terminal is grounded, the controller is electrically connected to the first detection terminal, and the detection circuit feeds back an electrical signal to the controller through the first detection terminal;

[0017] Alternatively, the detection circuit may further include a first load and a first power supply, with the first detection terminal electrically connected to the first power supply, the second detection terminal grounded via the first load, the controller electrically connected to the second detection terminal, and the detection circuit feeding back an electrical signal to the controller through the second detection terminal.

[0018] In some embodiments, the resistance strip is disposed on the housing, the second detection end is in movable contact with the resistance strip, and both the first detection end and the second detection end are disposed on the nursing part;

[0019] Alternatively, the resistance strip is disposed in the nursing section, the second detection end is in movable contact with the resistance strip, and both the first detection end and the second detection end are disposed in the housing.

[0020] In some embodiments, among the first detection end and the second detection end, the detection end that is in movable contact with the resistor strip is an elastic contact, and the resistor strip is provided with a groove arranged along its extension direction, and the elastic contact elastically abuts against the groove.

[0021] In some embodiments, the conductor portion includes a plurality of conductive contacts spaced apart along the movement direction of the care portion; when the driving device drives the movement of the care portion, the first detection end sequentially switches contact with each conductive contact according to the distribution order of the conductive contacts, and the detection circuit outputs a corresponding electrical signal to the controller according to the conductive contact contact contacted by the first detection end.

[0022] In some embodiments, the detection circuit further includes a second load and a second power supply. The first detection terminal is electrically connected to the second power supply via the second load. Each of the conductive contacts is grounded via a load of a different size. The controller is electrically connected to the first detection terminal. The detection circuit feeds back an electrical signal to the controller through the first detection terminal.

[0023] Alternatively, the detection circuit may further include a second load and a second power supply. The first detection terminal is grounded via the second load, and each of the conductive contacts is electrically connected to the second power supply via a load of a different size. The controller is electrically connected to the first detection terminal, and the detection circuit feeds back an electrical signal to the controller through the first detection terminal.

The treatment section is movably mounted on the housing, and the drive unit is connected to the treatment section to drive its movement relative to the housing. The controller is communicatively connected to the detection device and the drive unit. The detection device includes a detection circuit and a conductor. The detection circuit has a first detection terminal that makes active contact with the conductor. The position of the first detection terminal in contact with the conductor changes with the movement of the treatment section. Based on the position of the first detection terminal in contact with the conductor, the detection circuit outputs a corresponding electrical signal to the controller. Thus, the controller of the beauty device can determine the position reached by the treatment section based on the electrical signal fed back from the detection circuit of the detection device. Therefore, when the controller determines that the treatment section has reached a predetermined position (such as a working position), it can immediately stop the drive unit, ensuring the treatment section stops accurately at the predetermined position. Compared to existing beauty devices, this application's beauty device accurately determines the position of the treatment section through the controller based on the electrical signal fed back from the detection circuit, eliminating the need for a drive unit to precisely control the drive distance. The power part of the drive unit does not require a stepper motor; a common motor can be used. Because expensive stepper motors are not used, the cost of the beauty device is significantly reduced, enhancing its market competitiveness. Attached Figure Description

[0040] The technical solutions in the embodiments of this application will be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0041] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0042] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the term "and / or" throughout the text includes three solutions; taking A and / or B as an example, it includes technical solution A, technical solution B, and a technical solution that simultaneously satisfies A and B. Furthermore, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0043] Existing beauty devices utilize stepper motors for high-precision displacement control in their drive mechanisms to accurately move the treatment area to the working position. This precise control of the stepper motor's angular displacement allows for precise control of the treatment area's movement distance. However, the use of expensive stepper motors in the drive mechanisms of existing beauty devices results in high costs and poor market competitiveness. To address this issue of excessively high costs, this application proposes a new beauty device solution that effectively reduces costs and enhances the device's market competitiveness.

[0044] Combined with reference Figure 1 and Figure 2 In this embodiment, the beauty device includes a housing 10, a drive unit 20, a care unit 30, a controller 40, and a detection device 50.

[0045] The nursing section 30 is movably mounted on the housing 10, meaning the nursing section 30 can move relative to the housing 10. The drive device 20 is connected to the nursing section 30 to drive its movement relative to the housing 10. For example, the drive device 20 can drive the nursing section 30 to perform linear reciprocating motion relative to the housing 10, or it can drive the nursing section 30 to rotate relative to the housing 10, or it can simultaneously drive the nursing section 30 to perform linear reciprocating motion relative to the housing 10 and rotate it, etc. The beauty device can switch between working and non-working positions (such as the nursing section 30's resting or storage position when powered off) by driving the nursing section 30 relative to the housing 10 via the drive device 20, and / or switch the nursing section 30 between multiple working positions (for example, the beauty device has multiple working modes or levels, and different working modes or levels correspond to different working positions of the nursing section 30). For example, when the beauty device is started, the drive device 20 drives the care unit 30 to move to the working position; when the beauty device is turned off, the drive device 20 drives the care unit 30 to move back to the non-working position; when the beauty device switches working modes or levels, the drive device 20 drives the care unit 30 from the current position to the corresponding working position. In some embodiments, the drive device 20 can drive the care unit 30 to perform linear reciprocating motion relative to the housing 10, causing the care unit 30 to move and switch between working and non-working positions and / or multiple working positions; in some embodiments, the drive device 20 can drive the care unit 30 to rotate relative to the housing 10, causing the care unit 30 to rotate and switch between working and non-working positions and / or multiple working positions. The drive device 20 can be directly mounted on the housing 10 or mounted on a structural member fixed relative to the housing 10.

[0046] The controller 40 communicates with the detection device 50 and the drive device 20. This communication connection can be wired (i.e., wired communication) or wireless (i.e., wireless communication). The controller 40 can control the operating state of the drive device 20 by sending control signals or commands to the drive device 20, thereby controlling the movement state of the nursing unit 30; for example, the controller 40 sends a drive command to the drive device 20 to drive the nursing unit 30 to move, or the controller 40 sends a stop command to the drive device 20 to stop the drive device 20 from driving the nursing unit 30 to move, etc.

[0047] The detection device 50 includes a detection circuit 51 and a conductor part 52; the conductor part 52 is a component with a conductive part, which may be a metal such as copper or aluminum or a material such as graphite. The detection circuit 51 has a first detection terminal J1 that is in active contact (e.g., sliding contact or rolling contact) with the conductor portion 52, meaning that the first detection terminal J1 of the detection circuit 51 can move relative to the conductor portion 52. The position of the first detection terminal J1 in contact with the conductor portion 52 changes with the movement of the nursing portion 30. It can also be understood that when the driving device 20 drives the nursing portion 30 to move relative to the housing 10, the first detection terminal J1 and the conductor portion 52 also generate relative movement, causing the position of the first detection terminal J1 in contact with the conductor portion 52 to change continuously. At this time, the electrical parameters of the first detection terminal J1 of the detection circuit 51 (e.g., the electrical parameters include at least one of resistance, capacitance, and voltage) are constantly changing. The detection circuit 51 outputs a corresponding electrical signal to the controller 40 according to the position of the first detection terminal J1 in contact with the conductor portion 52. It can also be understood that when the position of the first detection terminal J1 in contact with the conductor portion 52 is different, the electrical parameters of the first detection terminal J1 are different, and the detection circuit 51 outputs a corresponding electrical signal to the controller 40 according to the electrical parameters of the first detection terminal J1. Thus, the controller 40 can determine the contact position between the first detection terminal J1 and the conductor 52 according to the electrical signal output by the detection circuit 51, and then determine the position reached by the nursing part 30 relative to the housing 10.

[0048] It should be noted that in the various figures of the embodiments of this application, the detection end with the arrow in the detection circuit 51 represents the detection end that is in active contact with the conductor part 52, and the detection end without the arrow in the detection circuit 51 represents the detection end that is fixedly connected to the conductor part 52.

[0049] In some embodiments, the mapping relationship between the position of the nursing unit 30 and the electrical signal can be preset in the controller 40. When the controller 40 controls the drive device 20 to drive the nursing unit 30 to move, the controller 40 can compare the electrical signal fed back by the detection circuit 51 with the reference signal corresponding to the predetermined position (such as the working position) in real time to determine whether the nursing unit 30 has moved to the predetermined position based on the comparison result. When the comparison result between the electrical signal fed back by the detection circuit 51 and the reference signal is consistent (of course, an allowable error range can be preset; if the difference between the electrical signal fed back by the detection circuit 51 and the reference signal is within the allowable error range, it is considered consistent; otherwise, it is considered inconsistent), it is determined that the nursing unit 30 has reached the predetermined position. At this time, the controller 40 controls the drive device 20 to stop driving, so that the nursing unit 30 stops accurately at the predetermined position. When the comparison result between the electrical signal fed back by the detection circuit 51 and the reference signal is inconsistent, the controller 40 controls the drive device 20 to drive the nursing unit 30 to continue moving.

[0050] The technical solution of the beauty device in this embodiment includes a housing 10, a drive device 20, a care unit 30, a controller 40, and a detection device 50. The care unit 30 is movably disposed on the housing 10. The drive device 20 is connected to the care unit 30 to drive the care unit 30 to move relative to the housing 10. The controller 40 is communicatively connected to the detection device 50 and the drive device 20. The detection device 50 includes a detection circuit 51 and a conductor 52. The detection circuit 51 has a first detection terminal J1 that is in contact with the conductor 52. The position of the first detection terminal J1 in contact with the conductor 52 changes with the movement of the care unit 30. The detection circuit 51 outputs a corresponding electrical signal to the controller 40 according to the position of the first detection terminal J1 in contact with the conductor 52. Thus, the controller 40 of the beauty device can determine the position reached by the movement of the treatment section 30 based on the electrical signal fed back by the detection circuit 51 of the detection device 50 (i.e., the electrical signal output by the detection circuit 51). Therefore, when the controller 40 determines that the treatment section 30 has reached a predetermined position (such as the working position), it controls the drive device 20 to immediately stop driving, ensuring that the treatment section 30 accurately stops at the predetermined position. Compared to existing beauty devices, the beauty device of this embodiment accurately determines the position of the treatment section 30 through the controller 40 based on the electrical signal fed back by the detection circuit 51, eliminating the need for precise control of the drive distance via the drive device 20. The power component of the drive device 20 does not require a stepper motor; a common motor can be used. Because expensive stepper motors are not used, the cost of the beauty device is significantly reduced, enhancing its market competitiveness.

[0051] Reference Figure 1 In this embodiment, the driving device 20 is used to drive the nursing part 30 to reciprocate relative to the housing 10 along the first direction F1 as an example. The driving device 20 drives the nursing part 30 to reciprocate along the first direction F1 so that the nursing part 30 can move and switch between working and non-working positions, or move and switch between multiple working positions.

[0052] In some embodiments, the drive device 20 may also be used to drive the nursing unit 30 to rotate relative to the housing 10. The drive device 20 drives the nursing unit 30 to rotate relative to the housing 10, thereby switching the nursing unit 30 between a working position and a non-working position, or between multiple working positions. In some embodiments, the drive device 20 is used to drive the nursing unit 30 to reciprocate relative to the housing 10 along a first direction F1 and to rotate relative to the housing 10. For example, the drive device 20 drives the nursing unit 30 to perform a helical telescopic movement along the first direction F1. Of course, in other embodiments, the drive device 20 may be used to drive the nursing unit 30 to perform other forms of movement relative to the housing 10 (such as oscillation).

[0053] Reference Figure 4 and Figure 5In some embodiments, one of the conductor portion 52 and the first detection terminal J1 is disposed in the care portion 30, and the other is disposed in the housing 10; that is, the conductor portion 52 is disposed in the care portion 30, and the first detection terminal J1 is disposed in the housing 10 (see reference). Figure 4 Alternatively, the conductor portion 52 is disposed on the housing 10, and the first detection end J1 is disposed on the nursing portion 30 (see reference). Figure 5 Thus, when the driving device 20 drives the nursing unit 30 to move relative to the housing 10, the conductor 52 moves relative to the first detection end J1, causing the contact position between the first detection end J1 and the conductor 52 to change continuously. The electrical parameters of the first detection end J1 of the detection circuit 51 change continuously. The electrical signal output by the detection circuit 51 to the controller 40 according to the contact position between the first detection end J1 and the conductor 52 also changes continuously. The controller 40 can determine the current contact position between the first detection end J1 and the conductor 52 based on the current feedback electrical signal from the detection circuit 51 (i.e., the current output electrical signal from the detection circuit 51), which corresponds to determining the current position reached by the nursing unit 30.

[0054] The conductor portion 52 or the first detection end J1 can be directly disposed on the nursing part 30 or the housing 10, or indirectly disposed on the nursing part 30 or the housing 10. The conductor portion 52 being indirectly disposed on the nursing part 30 can mean that the conductor portion 52 is disposed on a component fixed to the nursing part 30, such as the conductor portion 52 being disposed on the drive end of the drive device 20 fixedly connected to the nursing part 30. The first detection end J1 being indirectly disposed on the housing 10 can mean that the first detection end J1 is disposed on a component fixed to the housing 10.

[0055] In some embodiments, the housing 10 may have a mounting cavity 11, in which the care unit 30 is mounted. The mounting cavity 11 has an opening for the care unit 30 to extend or protrude. The beauty device can perform beauty care work by driving the care unit 30 to extend from the opening or to protrude from the opening. For example, when the beauty device is off, the drive device 20 can drive the care unit 30 back into the mounting cavity 11 for storage; when the beauty device is on, the drive device 20 can drive it to move towards the opening end so that one end of the care unit 30 extends out of the mounting cavity 11 from the opening to reach the working position for use. As another example, when the beauty device is off, the drive device 20 can drive the care unit 30 to move to a position offset from the opening to hide the care unit 30; when the beauty device is on, the drive device 20 can drive the care unit 30 to move to a position opposite to the opening of the mounting cavity 11 (i.e., the care unit 30 reaches the working position) to expose the care unit 30 for use. In this embodiment of the beauty device solution, the care unit 30 is installed in the housing 10 by setting the installation cavity 11, so as to better protect the care unit 30. At the same time, by storing the care unit 30 in the installation cavity 11, the overall appearance of the beauty device is simpler and more beautiful.

[0056] In some embodiments, the conductor portion 52 and the first detection end J1 may be respectively disposed on the outer wall of the nursing portion 30 and the inner wall of the mounting cavity 11 (i.e., the conductor portion 52 is disposed on the outer wall of the nursing portion 30 and the first detection end J1 is disposed on the inner wall of the mounting cavity 11, or the conductor portion 52 is disposed on the inner wall of the mounting cavity 11 and the first detection end J1 is disposed on the outer wall of the nursing portion 30); of course, in some other embodiments, the conductor portion 52 and the first detection end J1 may also be respectively disposed at other positions of the nursing portion 30 and the housing 10.

[0057] In some embodiments, the care unit 30 may include a reservoir for holding water or serum (e.g., a serum bottle, a nutrient solution bottle, etc.). Of course, in some embodiments, the care unit 30 may also include a radiofrequency care head or an ultrasonic care head, etc.

[0058] like Figure 3 As shown, in this embodiment, the conductor portion 52 may include a resistance strip 521 extending along the movement direction of the nursing portion 30. The detection circuit 51 may also have a second detection terminal J2 electrically connected to the resistance strip 521. The first detection terminal J1 of the detection circuit 51 is in active contact with the resistance strip 521, that is, the first detection terminal J1 can move relative to the resistance strip 521 and maintain a conductive connection with the resistance strip 521. The resistance value between the first detection terminal J1 and the second detection terminal J2 changes with the movement of the nursing portion 30. The detection circuit 51 outputs a corresponding electrical signal to the controller 40 based on the resistance value between the first detection terminal J1 and the second detection terminal J2. It should be noted that the figure in this embodiment only shows the resistance strip 521 as a straight strip. In other embodiments, the resistance strip 521 may also be a strip of other shapes (such as a serrated strip, a wavy strip, etc.), and the resistance strip 521 may also be a sheet, a wire, a block, etc.

[0059] In this embodiment of the beauty device, when the controller 40 controls the drive device 20 to drive the care unit 30 to move, the first detection terminal J1 moves relative to the resistor bar 521 along the extension direction of the resistor bar 521. The position where the first detection terminal J1 contacts and conducts with the resistor bar 521 continuously changes, causing the resistance value between the first detection terminal J1 and the second detection terminal J2 to continuously change (continuously increase or continuously decrease). Thus, the detection circuit 51 outputs a correspondingly changing electrical signal to the controller 40 based on the continuously changing resistance value (i.e., the resistance value between the first detection terminal J1 and the second detection terminal J2). The controller 40 then determines the real-time position of the care unit 30 based on the electrical signal output by the detection circuit 51. When the controller 40 determines that the care unit 30 has reached a predetermined position (such as the working position), it controls the drive device 20 to stop driving, and the care unit 30 stops at the predetermined position. In this embodiment, the conductor portion 52 of the detection device 50 adopts a resistance strip 521 that extends along the movement direction of the care portion 30. The first detection terminal J1 of the detection circuit 51 is in active contact with the resistance strip 521, and the second detection terminal J2 of the detection circuit 51 is electrically connected to the resistance strip 521. The detection circuit 51 feeds back a corresponding electrical signal to the controller 40 based on the resistance value between the first detection terminal J1 and the second detection terminal J2. The structure, connection, and principle of the detection device 50 are simple, and the implementation cost is low, thereby further reducing the cost of the beauty device.

[0060] Reference Figure 3 and Figure 6In some embodiments, the second detection terminal J2 of the detection circuit 51 can be fixed in position to be electrically connected to the resistor strip 521. When the nursing part 30 moves (i.e. the nursing part 30 moves relative to the housing 10), the first detection terminal J1 moves along the resistor strip 521. In this embodiment of the beauty device solution, when the driving device 20 drives the care unit 30 to move relative to the housing 10, the first detection end J1 moves along the resistance bar 521. Since the position of the second detection end J2 electrically connected to the resistance bar 521 remains fixed, the length of the portion of the resistance bar 521 between the first detection end J1 and the second detection end J2 will continuously increase or decrease as the first detection end J1 moves along the resistance bar 521. Consequently, the resistance value between the first detection end J1 and the second detection end J2 will continuously increase or decrease. The detection circuit 51 outputs an electrical signal of corresponding magnitude to the controller 40 based on the resistance value between the first detection end J1 and the second detection end J2. The controller 40 then determines the position to which the care unit 30 has moved based on the magnitude of the electrical signal fed back by the detection circuit 51 (for example, the controller 40 determines the position of the care unit 30 corresponding to the current magnitude of the electrical signal fed back by the detection circuit 51 based on a pre-set mapping relationship between the magnitude of the electrical signal and the position of the care unit 30, i.e., determines the current position to which the care unit 30 has moved). Wherein, with the position of the second detection terminal J2 electrically connected to the resistor strip 521 fixed, the second detection terminal J2 can be located on the same structure as the first detection terminal J1, or the second detection terminal J2 can be located on different structures from the first detection terminal J1; for example, refer to Figure 4 The first detection terminal J1 is located on the housing 10. The second detection terminal J2 in this figure can be located on either the housing 10 or the nursing unit 30. For example, refer to... Figure 5 The first detection terminal J1 is located on the nursing section 30. The second detection terminal J2 in the figure can be located on the nursing section 30 or on the housing 10.

[0061] Reference Figure 7In some embodiments, the second detection terminal J2 of the detection circuit 51 may also be in active contact with the resistance strip 521. When the care unit 30 moves (i.e., the care unit 30 moves relative to the housing 10), the first detection terminal J1 and the second detection terminal J2 move synchronously along the resistance strip 521, and the cross-sectional area of ​​the resistance strip 521 gradually increases along its length. In this embodiment of the beauty device solution, when the driving device 20 drives the care unit 30 to move relative to the housing 10, the first detection terminal J1 and the second detection terminal J2 move synchronously along the resistance strip 521. Although the length of the portion of the resistance strip 521 between the first detection terminal J1 and the second detection terminal J2 remains unchanged, since the cross-sectional area of ​​the resistance strip 521 in this embodiment gradually increases along its length, the cross-sectional area at the position where the resistance strip 521 contacts the first detection terminal J1 and the cross-sectional area at the position where the resistance strip 521 contacts the second detection terminal J2 will continuously increase. As the resistance of a metal conductor is inversely proportional to its cross-sectional area, the resistance value of the portion of the resistor bar 521 located between the first detection end J1 and the second detection end J2 will continuously increase or decrease as the first detection end J1 and the second detection end J2 move synchronously along the resistor bar 521. The detection circuit 51 then outputs an electrical signal of corresponding magnitude to the controller 40 based on the resistance value between the first detection end J1 and the second detection end J2. The controller 40 then determines the position to which the nursing unit 30 has moved based on the magnitude of the electrical signal fed back by the detection circuit 51.

[0062] Reference Figure 10 In some embodiments, the detection device 50 may be configured such that: a resistance strip 521 is disposed on the housing 10, the cross-sectional area of ​​the resistance strip 521 gradually increases along its length, the first detection terminal J1 and the second detection terminal J2 of the detection circuit 51 are both in active contact with the resistance strip 521, and the first detection terminal J1 and the second detection terminal J2 of the detection circuit 51 are both disposed on the nursing section 30; that is, when the nursing section 30 moves relative to the housing 10, the first detection terminal J1 and the second detection terminal J2 move together with the nursing section 30 to move along the resistance strip 521 disposed on the housing 10. Alternatively, refer to Figure 11 In some embodiments, the detection device 50 may also be configured such that: a resistance strip 521 is disposed on the nursing section 30, the cross-sectional area of ​​the resistance strip 521 gradually increases along its length, the first detection terminal J1 and the second detection terminal J2 of the detection circuit 51 are in active contact with the resistance strip 521, and the first detection terminal J1 and the second detection terminal J2 of the detection circuit 51 are both disposed on the housing 10; that is, when the nursing section 30 moves relative to the housing 10, the resistance strip 521 moves with the nursing section 30, thereby causing the first detection terminal J1 and the second detection terminal J2 disposed on the housing 10 to move along the resistance strip 521 relative to the resistance strip 521.

[0063] Reference Figure 6 and Figure 7 In some embodiments, the detection circuit 51 may be configured as follows: the detection circuit 51 includes a first load R1 (such as a resistor) and a first power supply VDD1. The first detection terminal J1 of the detection circuit 51 is electrically connected to the first power supply VDD1 via the first load R1. The second detection terminal J2 of the detection circuit 51 is grounded. The controller 40 is electrically connected to the first detection terminal J1. The detection circuit 51 feeds back an electrical signal to the controller 40 through the first detection terminal J1. In this embodiment, the electrical signal fed back by the detection circuit 51 to the controller 40 through the first detection terminal J1 is the voltage of the first detection terminal J1, that is, the voltage division of the resistor between the first detection terminal J1 and the second detection terminal J2. The principle of the detection circuit 51 in this embodiment is as follows: when the nursing unit 30 moves, the resistance value between the first detection terminal J1 and the second detection terminal J2 continuously increases or decreases, and thus the voltage drop across the resistor between the first detection terminal J1 and the second detection terminal J2 (i.e., the voltage of the first detection terminal J1) increases or decreases accordingly. In other words, the magnitude of the electrical signal (voltage) fed back to the controller 40 increases or decreases accordingly. Thus, the controller 40 determines the position to which the nursing unit 30 has moved based on the magnitude of the voltage fed back from the first detection terminal J1.

[0064] Reference Figure 8 and Figure 9 In some embodiments, the detection circuit 51 may also be configured as follows: the detection circuit 51 includes a first load R1 and a first power supply VDD1. The first detection terminal J1 of the detection circuit 51 is electrically connected to the first power supply VDD1, and the second detection terminal J2 of the detection circuit 51 is grounded through the first load R1. The controller 40 is electrically connected to the second detection terminal J2, and the detection circuit 51 feeds back an electrical signal to the controller 40 through the second detection terminal J2. In this embodiment, the electrical signal fed back by the detection circuit 51 to the controller 40 through the second detection terminal J2 is the voltage of the second detection terminal J2, i.e., the voltage drop across the first load R1. The principle of the detection circuit 51 in this embodiment is as follows: When the nursing unit 30 moves, the resistance value between the first detection terminal J1 and the second detection terminal J2 continuously increases or decreases. Consequently, the voltage drop across the resistor between the first detection terminal J1 and the second detection terminal J2 increases or decreases accordingly. Then, the voltage drop across the first load R1 (equal to the voltage output by the first power supply VDD1 minus the voltage drop across the resistor between the first detection terminal J1 and the second detection terminal J2) decreases or increases accordingly. That is, the magnitude of the electrical signal (voltage) fed back to the controller 40 decreases or increases accordingly. Thus, the controller 40 determines the position to which the nursing unit 30 has moved based on the magnitude of the voltage fed back from the second detection terminal J2.

[0065] In some embodiments, in the first detection terminal J1 and the second detection terminal J2 of the detection circuit 51, the detection terminal that is in movable contact with the resistor strip 521 is an elastic contact, that is, the first detection terminal J1 is an elastic contact, or both the first detection terminal J1 and the second detection terminal J2 are elastic contacts; the resistor strip 521 is provided with a groove arranged along its extension direction, and the elastic contact elastically abuts against the groove. In this embodiment, the detection terminal of the detection circuit 51 that is in movable contact with the resistor strip 521 is an elastic contact, and the resistor strip 521 is provided with a groove arranged along its extension direction, so that the elastic contact abuts against the groove. In this way, when the nursing part 30 moves, the detection terminal of the detection circuit 51 that is in movable contact with the resistor strip 521 moves along the groove of the resistor strip 521, which improves the stability and smoothness of the movement of the detection terminal of the detection circuit 51 along the resistor strip 521, and the use of an elastic abutment groove for the detection terminal of the detection circuit 51 that is in movable contact with the resistor strip 521 ensures the stability of the contact with the resistor strip 521. Of course, in other embodiments, the detection end of the detection circuit 51 and the resistor strip 521 may be designed in other ways to increase the stability, smoothness and contact stability of their relative movement.

[0066] Reference Figure 12 In this embodiment, the conductor portion 52 may include a plurality of conductive contacts G spaced apart along the movement direction of the nursing portion 30. When the driving device 20 drives the movement of the nursing portion 30, the first detection terminal J1 of the detection circuit 51 sequentially switches contact (i.e., conducts) with each conductive contact G according to the distribution order of the conductive contacts G. The detection circuit 51 outputs a corresponding electrical signal to the controller 40 based on the conductive contact G contacted by the first detection terminal J1. Alternatively, the conductive contacts G may be located on the nursing portion 30 and the first detection terminal J1 may be located on the housing 10, or the conductive contacts G may be located on the housing 10 and the first detection terminal J1 may be located on the nursing portion 30.

[0067] In this embodiment of the beauty device, when the controller 40 controls the drive device 20 to drive the care unit 30 to move, the first detection end J1 and the conductor part 52 generate relative movement in the movement direction of the care unit 30. The contact position between the first detection end J1 and the conductor part 52 continuously changes, and the first detection end J1 sequentially switches contact with each conductive contact G. The electrical parameters of the first detection end J1 (for example, the electrical parameters may include one or more of resistance, capacitance, and voltage) change accordingly. Thus, the detection circuit 51 outputs a correspondingly changing electrical signal to the controller 40 according to the changing electrical parameters of the first detection end J1. The controller 40 then determines the real-time position of the care unit 30 according to the electrical signal output by the detection circuit 51. When the controller 40 determines that the care unit 30 has reached a predetermined position (such as the working position), it controls the drive device 20 to stop driving, and the care unit 30 stops at the predetermined position. In this embodiment, the conductor part 52 of the detection device 50 uses multiple conductive contacts G that are spaced apart along the movement direction of the care part 30. When the care part 30 moves, the first detection terminal J1 of the detection circuit 51 sequentially switches the conductive contacts G it contacts. The detection circuit 51 feeds back the corresponding electrical signal to the controller 40 according to the conductive contacts G that the first detection terminal J1 contacts. The structure, connection and principle of the detection device 50 are simple and the implementation cost is low, thereby further reducing the cost of the beauty device.

[0068] In specific applications of the beauty device, the number and density of conductive contacts G can be designed according to requirements. For example, when the beauty device needs to continuously detect the position of the treatment area 30, many conductive contacts G can be set and arranged very densely, that is, the interval between the conductive contacts G is very small, so that when the first detection end J1 just leaves contact with a conductive contact G, it can just make contact with the next adjacent conductive contact G. When the beauty device only needs the detection device 50 to detect a few fixed positions of the treatment area 30, fewer conductive contacts G can be set and arranged more sparsely, that is, the interval between the conductive contacts G is larger, and the conductor part 52 located in the interval between the conductive contacts G can be made of insulating material; the detection circuit 51 can output a preset signal to the controller 40 or not output an electrical signal when the first detection end J1 contacts the interval between the conductive contacts G (that is, when it is not in contact with the conductive contacts G).

[0069] Reference Figure 13In some embodiments, the detection circuit 51 may be configured as follows: the detection circuit 51 includes a second load R2 and a second power supply VDD2. The first detection terminal J1 of the detection circuit 51 is electrically connected to the second power supply VDD2 via the second load R2. Each conductive contact G is grounded via a load of different sizes. The controller 40 is electrically connected to the first detection terminal J1. The detection circuit 51 feeds back an electrical signal to the controller 40 through the first detection terminal J1. In this embodiment, the electrical signal fed back by the detection circuit 51 to the controller 40 through the first detection terminal J1 is the voltage of the first detection terminal J1, that is, the voltage drop across the load electrically connected to the conductive contact G that the first detection terminal J1 contacts. The principle of the detection circuit 51 in this embodiment is as follows: When the nursing section 30 moves, the first detection terminal J1 and the conductor section 52 generate relative movement in the direction of movement of the nursing section 30, so that the first detection terminal J1 sequentially switches the conductive contact G it contacts, that is, the pull-down load of the first detection terminal J1 (that is, the load between the conductive contact G contacted by the first detection terminal J1 and the ground) switches accordingly. Since the load between each conductive contact G and the ground is different, the voltage of the first detection terminal J1 will change with the switching of the contacting conductive contact G. Thus, the controller 40 can determine the position to which the nursing section 30 has moved based on the voltage magnitude fed back by the first detection terminal J1.

[0070] Reference Figure 14 In some embodiments, the detection circuit 51 can also be configured as follows: the detection circuit 51 includes a second load R2 and a second power supply VDD2. The first detection terminal J1 of the detection circuit 51 is grounded through the second load R2. Each conductive contact G is electrically connected to the second power supply VDD2 through a load of different sizes. The controller 40 is electrically connected to the first detection terminal J1. The detection circuit 51 feeds back an electrical signal to the controller 40 through the first detection terminal J1. In this embodiment, the electrical signal fed back by the detection circuit 51 to the controller 40 through the first detection terminal J1 is the voltage of the first detection terminal J1, i.e., the voltage division across the second load R2. The principle of the detection circuit 51 in this embodiment is as follows: When the nursing section 30 moves, the first detection terminal J1 and the conductor section 52 move relative to each other in the direction of movement of the nursing section 30, so that the first detection terminal J1 switches the conductive contact G it contacts in turn. That is, the pull-up resistor of the first detection terminal J1 (that is, the load between the conductive contact G contacted by the first detection terminal J1 and the second power supply VDD2) switches accordingly. Since the load between each conductive contact G and the second power supply VDD2 is different, the voltage of the first detection terminal J1 (that is, the voltage division on the second load R2) will change with the switching of the contacting conductive contact G. Thus, the controller 40 can determine the position to which the nursing section 30 has moved based on the voltage feedback from the first detection terminal J1.
