Therefore, before the cosmetic instrument is used normally, it is necessary to detect whether the spring is deformed or whether there are injection molding burrs in the spring mounting hole. Since the spring mounting hole is a small hole of about 1.8mm, the deformation of the spring or the existence of injection molding burrs in the spring mounting hole will affect the contact and conduction of the spring and the electrode.

[0043] Each connecting spring in the application can form a series test circuit with the electrode block, the test resistor and the test indicator light 38. By observing whether the test indicator light 38 is lit, it can be determined whether the connection of the connecting spring with the electrode block and the conduction plate is normal, thereby improving the efficiency and accuracy of the cosmetic instrument electrical connection test.

For the cold compress mode, a special cold compress port is provided, and corresponding electrode blocks and conduction plates are arranged in the cold compress port, and the electrode blocks and the conduction plates are electrically connected by connecting springs. Regardless of which module, the positive electrode and the negative electrode in the electrode block can form a test circuit with the test indicator light 38 and the test resistor in the conduction plate, and the test circuit can be determined by the lighting state of the test indicator light 38.

When the cold compress positive electrode 211 and the cold compress negative electrode 212 in the cold compress electrode block 21 are powered, they are in contact with the human body and form a conduction circuit with micro-current with the skin of the human body, and the skin is cooled to realize the cold compress effect on the skin.
[0063] Specifically, the test tool includes a cold compress detection plate 34 and a cold compress test indicator, and the cold compress detection plate 34 is provided with a cold compress test resistor.
[0064] Corresponding to the cold compress end, the application is provided with a cold compress detection plate 34 and a cold compress test indicator, wherein the cold compress test plate is provided with a cold compress test resistor. When the cold compress test plate is in abutment with the cold compress electrode block 21, the positive electrode and the negative electrode in the cold compress electrode block 21 are in series with the cold compress test resistor and the cold compress test indicator to form a test circuit. At this time, the test tool is equivalent to the human body. After the cold compress positive electrode 211 and the cold compress negative electrode 212 in the cold compress electrode block 21 are powered, they are respectively in contact with the cold compress test resistor and the cold compress test indicator in the cold compress test plate and form a conduction circuit with micro-current with the cold compress test resistor and the cold compress test indicator. If the cold compress test indicator is lit, it indicates that the electrical connection between the cold compress electrode block 21, the cold compress connecting spring 222, the cold compress conduction plate 22, and the conductive end 2 in the cosmetic instrument is normal. The state of the cold compress test indicator monitors the device of the cold compress end electrical connection, which improves the efficiency and accuracy of the cold compress end electrical connection test of the cosmetic instrument.
[0065] Specifically, it further includes a temperature display assembly 37 and a cold compress temperature contact 36, the cold compress temperature contact 36 is arranged in the cold compress detection plate 34, and the cold compress temperature contact 36 is electrically connected with the temperature display assembly 37.
[0066] The cold compress temperature contact 36 is arranged in the cold compress detection plate 34. When the cold compress detection plate 34 abuts against the cold compress end, the cold compress temperature contact 36 abuts against the cold compress electrode block 21. When the electrical connection test of the cold compress end is performed, the test duration can be set. In the test duration, the temperature in the cold compress electrode block 21 decreases. At this time, the temperature in the cold compress electrode block 21 is transmitted to the temperature display assembly 37 through the cold compress temperature contact 36. By observing the temperature displayed in the temperature display assembly 37, whether the temperature of the cold compress electrode block 21 reaches the preset range in the test duration can be determined. If the temperature reaches the preset range, it indicates that the cold compress end has normal cooling. If the temperature does not reach the preset range, it indicates that the cold compress end has unqualified cooling, and needs to be disassembled for maintenance. The cold compress end electrical performance test of the present application can realize the detection of the cooling function of the cold compress end, that is, the operation detection of whether the electrical connection and the cooling function are normally operated. The cold compress temperature detection and the cold compress end electrical connection detection are combined in the same test tool. Compared with the manual detection method, the cosmetic instrument detection efficiency and detection accuracy are improved.
[0067] Specifically, the cold compress electrode block 21 includes a cold compress anode 211 and a cold compress cathode 212.
[0068] The present application can be provided with a single cold compress anode 211 and a cold compress cathode 212 in the cold compress end, or a plurality of cold compress anodes 211 and cold compress cathodes 212 can be provided for adjusting the action point on the human skin and adjusting the cold compress effect. When the cold compress anode and the cold compress cathode 212 are multiple, the plurality of cold compress anodes 211 and the cold compress cathode are connected to the cold compress conductive block in the cold compress connecting spring 222. The cold compress conductive block is connected to the anode and the cathode corresponding to the power supply or the battery in the conductive end 2 to ensure that the anode of the power supply is in communication with the cold compress anode 211, and the cathode of the power supply is in communication with the cold compress cathode 212. When the cold compress anode 211 and the cold compress cathode 212 are multiple, each cold compress anode 211 and each cold compress cathode need to form a test circuit. The present embodiment can only form one test circuit. When the cold compress anode 211 and the cold compress cathode 212 are multiple, a plurality of test circuits need to be formed to ensure that all cold compress connecting springs 222 corresponding to the cold compress anode and the cold compress cathode 212 are located in the test circuit to ensure the comprehensiveness of the cold compress connecting spring 222 test and avoid missing the test of a cold compress connecting spring 222.
[0069] Embodiment 3
[0070] As shown in the Figures 1-7 The present embodiment provides a cosmetic instrument test tool for simultaneously performing electrical connection tests on the hot compress end and the cold compress end of the cosmetic instrument.
[0071] The cosmetic instrument includes a cosmetic instrument body 1 and a wire end, and the cosmetic instrument body 1 is provided with a battery, and the battery is electrically connected with the conductive end 2.

When the hot compress anode 111 and the hot compress cathode 112 in the hot compress electrode block 11 are powered, they are in contact with the human body, form a conductive circuit with micro-current with the human skin, and are heated, thereby realizing the hot compress effect on the skin.
[0073] The hot compress electrode block 11 in the embodiment includes six hot compress anodes 111 and four hot compress cathodes 112.
[0074] As shown in the drawings, Figures 1-5 The cold compress end includes a cold compress electrode block 21, a cold compress conductive plate 22 and a cold compress connecting spring 222. The cold compress electrode block 21 includes at least one cold compress anode 211 and at least one cold compress cathode 212. The cold compress conductive plate 22 is provided with a cold compress conductive block corresponding to the cold compress anode 211 and the cold compress cathode 212. The first end of the cold compress connecting spring 222 is in abutment with the cold compress anode or the cold compress cathode 212, and the second end of the cold compress connecting spring 222 is in abutment with the cold compress conductive block. The cold compress conductive block is connected with the positive and negative poles of the power supply through the conductive end 2. The positive pole of the power supply is transmitted to the cold compress anode 211 in the cold compress electrode block 21 through the conductive end 2, the cold compress conductive block in the cold compress conductive plate 22 and the cold compress connecting spring 222 in sequence, and the negative pole of the power supply is transmitted to the cold compress cathode 212 in the cold compress electrode block 21 through the conductive end 2, the cold compress conductive block in the cold compress conductive plate 22 and the cold compress connecting spring 222 in sequence. When the cold compress anode 211 and the cold compress cathode 212 in the cold compress electrode block 21 are powered, they are in contact with the human body, form a conductive circuit with micro-current with the human skin, and are cooled, thereby realizing the cold compress effect on the skin.
[0075] The cold compress electrode block 21 in this embodiment includes a cold compress positive electrode 211 and a cold compress negative electrode 212.
[0076] like Figures 6-7 As shown, the testing fixture of this application includes a test substrate 31, in which a test station 32 is provided. The test station 32 is used to place and accommodate the beauty device body 1. A hot compress detection plate 33 is provided above the test station 32, and a cold compress detection plate 34 is provided below the test station 32. A temperature display component 37 and hot compress test indicator lights and cold compress test indicator lights are provided on the side of the test substrate 31. Through wiring in the test substrate 31, the hot compress test indicator lights and the hot compress test resistors in the hot compress detection plate 33 are electrically connected, and the cold compress test indicator lights and the cold compress test resistors in the cold compress detection plate 34 are electrically connected.
[0077] To facilitate the installation and disassembly of the beauty device in the testing fixture, this application sets the position of the cold compress detection plate 34 to be fixed. When the beauty device is placed in the testing station 32, the cold compress electrode block 21 is electrically connected to the cold compress detection plate. Simultaneously, the hot compress detection plate 33 is designed to be height-adjustable. Specifically, the hot compress detection plate 33 is connected to the pressure drive 40 via a pressure plate 42. The pressure drive 40 can move the pressure plate 42 and the hot compress detection plate 33 relative to the cold compress detection plate 34, thereby achieving electrical connection or separation between the hot compress detection plate 33 and the hot compress end. To ensure the stability of the lifting, this application provides pressure guide posts 41 on both sides of the pressure drive 40. The pressure plate 42 has guide post holes adapted to the pressure guide posts 41, with the pressure guide posts 41 penetrating the pressure holes. When the pressure drive 40 moves the pressure plate 42 up and down, it ensures that the pressure plate 42 moves along the pressure guide posts 41. When the pressure plate 42 descends, it ensures that the heat compress detection plate 33 and the cold compress detection plate 34 are electrically connected to the heat compress electrode block 11 and the cold compress electrode block 21, respectively. When the pressure plate 42 rises, it allows for the placement and removal of the beauty device.
[0078] The testing fixture of this application includes a heat therapy detection plate 33 and a heat therapy test indicator light. The heat therapy detection plate 33 is provided with a heat therapy test resistor. When the heat therapy test plate abuts against the heat therapy electrode block 11, the positive and negative electrodes of the heat therapy electrode block 11 are connected in series with the heat therapy test resistor and the heat therapy test indicator light to form a test circuit. At this time, the testing fixture is equivalent to the human body. After the heat therapy positive electrode 111 and heat therapy negative electrode 112 in the heat therapy electrode block 11 are energized, they respectively contact the heat therapy test resistor and the heat therapy test indicator light in the heat therapy test plate, and form a conductive circuit with microcurrent with the heat therapy test resistor and the heat therapy test indicator light. If the heat therapy test indicator light is lit, it means that the electrical connection between the heat therapy electrode block 11, the heat therapy connecting spring 122, the heat therapy conductive plate 12 and the conductive end 2 in the beauty device is normal.
[0079] As shown in Figure 3 and Figure 4 shown, six hot compress test resistors are arranged in the hot compress detection plate 33, six hot compress anodes 111 and four hot compress cathodes 112 form six test circuits, and two hot compress cathodes 112 in the six test circuits are shared, so as to ensure that all hot compress electrodes and hot compress cathodes 112 corresponding to the hot compress connecting springs 122 are located in the test circuit.
[0080] The cold compress test plate in the application is provided with a cold compress test resistor. When the cold compress test plate abuts against the cold compress electrode block 21, the anode and the cathode in the cold compress electrode block 21 form a test circuit in series with the cold compress test resistor and the cold compress test indicator. At this time, the test tool is equivalent to the human body, and after the cold compress anode 211 and the cold compress cathode 212 in the cold compress electrode block 21 are electrified, they respectively contact the cold compress test resistor and the cold compress test indicator in the cold compress test plate, and form a conduction circuit with micro-current with the cold compress test resistor and the cold compress test indicator. If the cold compress test indicator is lit, it indicates that the electrical connection between the cold compress electrode block 21, the cold compress connecting spring 222, the cold compress conduction plate 22 and the conductive end 2 in the beauty instrument is normal.
[0081] In the application, each connecting spring can form a series test circuit with the electrode block, the test resistor and the test indicator 38. By observing whether the test indicator 38 is lit, it can be judged whether the connection of the connecting spring with the electrode block and the conduction plate is normal, thereby improving the efficiency and accuracy of the electrical connection test of the beauty instrument.
