Abstract

[0002] The curling iron contains a rotary motor that drives the curling iron to rotate. Existing technology for the life test of the rotary motor mainly controls the left and right rotation of the rotary motor. During normal use, when the curling iron rotates left and right, hair wraps around the curling iron, creating braking torque. However, the existing technology test cannot simulate this situation, which leads to inaccurate overall life test results. Utility Model Content

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0018] refer to Figure 1 As shown, the test apparatus of this embodiment, used for life testing of the curling iron 2, includes a base 1, a first support 3, a second support 4, a third support 5, and a hysteresis brake 6. The front of the curling iron 2 can rotate, and a left-turn button 7 and a right-turn button 8 are provided in the middle to control the left and right rotation of the curling iron 2.
[0019] The base 1 is a rectangular frame structure formed by four aluminum profiles. The upper surfaces of the two aluminum profiles along its length are provided with first grooves 11.
[0020] First support 3, as shown Figure 2 As shown, the base 1 is located at its rear end and includes a fixing plate 17, a baffle 18, a guide rod 19, a clamping plate 20, and an adjustment knob, wherein:
[0021] Fixing plate 17 is fixed to base 1;
[0022] The baffle 18 consists of two pieces, which are vertically fixed to both ends of the fixing plate 17;
[0023] The guide rods 19 are in two sets, each set consisting of two vertically parallel guide rods 19. Both ends of each guide rod 19 are fixed to two baffles 18, serving a guiding function.
[0024] The clamping plates 20 are in two sets, each set including a left clamping plate 20 and a right clamping plate 20. They are provided with through holes for the guide rods 19 to pass through, so that the left clamping plate 20 and the right clamping plate 20 can slide on the corresponding guide rods 19. Both the left clamping plate 20 and the right clamping plate 20 are provided with arc-shaped grooves that match the shape of the curling iron 2, so that the two clamping plates 20 can clamp and fix the curling iron 2 well.
[0025] The adjustment knob is threaded onto the baffle 18. Each adjustment knob corresponds to a clamp 20. The position of the clamp 20 can be adjusted by adjusting the adjustment knob, so that the curling iron 2 can be clamped easily.
[0026] The second bracket 4 is set at the front end of the base 1 and is used to fix the hysteresis brake 6.
[0027] Hysteresis brake 6, such as Figure 4As shown, the device, fixed on the second bracket 4, consists of two main parts: a rotor 21 and stator poles 22. The rotor 21 is made of a special hysteresis material, and there is a certain gap in the stator poles 22. The rotor 21 rotates within this gap. By setting the voltage of the hysteresis brake, a stable and effective output current is regulated. When the coil is energized, a magnetic field is generated in the gap, causing the rotor to produce a hysteresis effect. When the hysteresis rotor rotates against the hysteresis force under the action of an external force, a rated torque is generated. The torque of the hysteresis brake is adjusted by controlling the magnitude of the DC current passing through the electromagnetic coil. The torque is only related to the magnitude of the excitation current to successfully simulate the load effect during product operation. It is a conventional product available on the market in the prior art, so it is not elaborated in detail in this embodiment. This embodiment simply applies the hysteresis brake 6 to the test device. The hysteresis brake 6 is connected to the rotating part at the front end of the curling iron 2 through a connector. When the curling iron 2 rotates, it needs to drive the hysteresis brake 6. In this way, the hysteresis brake 6 can provide braking torque to the curling iron 2, simulating the real application scenario of the curling iron 2. Moreover, the magnitude of the braking torque provided by the hysteresis brake 6 can also be adjusted, which can make the test more accurate.
[0028] Third support 5, such as Figure 3 As shown, it includes a column 12, a crossbar 13, a fixing block 14, a first trigger head 9, and a second trigger head 10, wherein:
[0029] There are two columns 12, which are respectively set on two aluminum profiles in the length direction. The bottom of the column 12 is provided with a slider for sliding connection in the first slide groove 11. After the position of the column 12 is determined, the column 12 can be locked on the base 1 by a locking member. The column 12 is also provided with a second slide groove 15 in the vertical direction.
[0030] There is one horizontal bar 13, with sliders at both ends, which can be slidably connected to the second slide groove 15 of the two columns 12. This means that the horizontal bar 13 can slide vertically on the two columns 12. After the position of the horizontal bar 13 is determined, the horizontal bar 13 can also be locked on the column 12 by the locking member. The horizontal bar 13 is also provided with a third slide groove 16 in the horizontal direction.
[0031] The fixing block 14 is provided with a slider and can be slidably connected in the third slide groove 16 of the crossbar 13. In this way, the fixing block 14 can slide horizontally on the crossbar 13. After the position of the fixing block 14 is determined, the fixing block 14 can also be locked on the crossbar 13 by the locking member.
[0032] The first trigger head 9 and the second trigger head 10 are elastic compression members used to trigger the left turn button 7 and the right turn button 8. They are both installed at the lower end of the fixed block 14 and are driven to move vertically by the power mechanism.
[0033] The working principle of this embodiment is as follows: First, the user installs the curling iron 2 onto the first bracket 3. At the same time, the rotating part of the front end of the curling iron 2 should be connected to the hysteresis brake 6. Then, the position of the third bracket 5 is adjusted so that the first trigger head 9 and the second trigger head 10 are exactly above the left turn button 7 and the right turn button 8. Then, the hysteresis brake 6 can be controlled to provide braking torque to the rotation of the curling iron 2. Finally, the first trigger head 9 and the second trigger head 10 are controlled to cycle, thereby making the curling iron 2 rotate left and right in a cycle.
