The present disclosure provides an elasticity detection device and a skin tester using the same. The elasticity detection device of the present disclosure is used for detecting the elasticity of an object to be detected. The elasticity detection device can be used for detecting the elasticity of human skin, and can also be used for detecting the elasticity of other elastic bodies. The elasticity detection device comprises a shell, and a reference detection assembly and an elasticity detection assembly which are movably connected to the shell. The reference detection assembly overcomes the elastic force of the first elastic device to move relative to the shell after being extruded by the object to be detected; the elastic detection assembly overcomes the elastic force of the second elastic device to move relative to the shell after being pressed by the object to be detected. During the movement, the reference detection device can trigger a reference electric signal, and the elasticity detection component can generate a detection electric signal for representing the elasticity of the object to be detected.

When the detection is carried out, the elastic detection device is pressed on an object to be detected in a manual mode, and the reference detection assembly and the elastic detection assembly move after being contacted with the object to be detected sequentially. Specifically, one of the reference detection assembly and the elastic detection assembly is configured to be pressed by the object to be detected in advance and then move, and the other one of the reference detection assembly and the elastic detection assembly is configured to be pressed by the object to be detected and then move. When benchmark determine module and elasticity determine module all with wait to detect the thing contact back, both receive the extrusion simultaneously and move. When the reference detection assembly moves to trigger the reference electric signal, the current electric signal of the elastic detection assembly is a detection electric signal for representing the elasticity of the object to be detected.

When the object to be detected is manually squeezed, it is difficult to accurately judge and control how much pressure should be applied to the object to be detected, and if the applied pressure is too large or too small, the measurement result and the actual elasticity of the object to be detected deviate. According to the elasticity detection device, after the elasticity detection device is extruded with an object to be detected, along with the change of extrusion force, an electric signal generated by the elasticity detection component also changes. However, the position of the reference detection component for triggering the reference electric signal is determined, when the reference detection component triggers the reference electric signal, the current electric signal generated by the elastic detection component is taken as the detection electric signal rather than the manually applied pressure on the basis of the extrusion force of the object to be detected borne by the elastic detection component. This disclosed elasticity detection device has set up benchmark determine module, can make the detected value of elasticity determine module output can not receive the influence of manual pressure magnitude of exerting from this, has guaranteed the uniformity that elasticity detected, has solved traditional elasticity and has detected the interference that causes because of exerting pressure magnitude, factors such as different users use to elasticity when detecting.

The presetting algorithm is well known in the art and will not be described in detail herein. Of course, on the basis of the above disclosure, L1, F1 of the reference detecting unit may be used only as a trigger electric signal, and the control unit may calculate the elasticity of the object to be detected based on only the detection electric signal F2 output by the elasticity detecting unit 42.

In one embodiment of the present disclosure, the length of the reference detection assembly extending out of the housing is equal to the length of the elastic detection assembly extending out of the housing. Specifically, the lengths of the first moving part 21 of the reference detection assembly and the second moving part 41 of the elastic detection assembly extending out of the housing are equal. The elasticity detecting device of the present disclosure moves relative to the housing when the first and second moving

parts

parts

21 and 41 are different, that is, the first and second moving

parts

21 and 41 do not move synchronously.

In one embodiment of the present disclosure, the difference in the moving speed is due to the first and second moving parts contacting the skin of the user at different positions. For example, in the structure of the first moving portion and the second moving portion, since the first moving portion is disposed around the second moving portion, the skin of the user can be preliminarily positioned by the first moving portion, and the moving speed of the second moving portion relative to the first moving portion toward the housing is different, so that during detection, when the first moving portion moves to enable the reference detection unit to trigger the reference electrical signal, the current electrical signal of the elastic detection unit serves as a detection electrical signal for representing the elasticity of the object to be detected.

The disclosure also provides an elasticity detection method implemented by the elasticity detection device.

The electric signal of the elastic detection unit reflects the stress of the second moving part, the stress of the second moving part reflects the pressure applied to the object to be detected, the pressure is applied manually, and the pressure is unstable, so that the electric signal of the elastic detection unit cannot accurately reflect the elasticity of the object to be detected.

The relative positions of the first moving part and the second moving part are fixed, the moving stroke of the first moving part is determined when the reference electric signal is triggered, the moving stroke of the second moving part is also fixed at the moment, and the electric signal of the elastic detection assembly at the moment is used as a detection electric signal, so that the detection electric signal can more accurately reflect the elasticity of the object to be detected.

At this time, the first moving portion and the second moving portion are both pressed by the object to be detected and move toward the inside of the housing. When the second moving part moves, the elastic detection unit generates an electric signal which can represent the pressure applied to the second moving part.

Similarly, the electrical signal of the elasticity detecting unit reflects the force applied by the second moving part, and the electrical signal is affected by the manual pressure and cannot accurately reflect the elasticity of the object to be detected. The relative positions of the first moving part and the second moving part are fixed, the moving stroke of the first moving part is determined when the reference electric signal is triggered, the moving stroke of the second moving part is also fixed at the moment, and the electric signal of the elastic detection assembly at the moment is used as a detection electric signal, so that the detection electric signal can more accurately reflect the elasticity of the object to be detected.
