[0026] Please also read Figure 1 and Figure 2The present embodiment provides a shaver, comprising a shell 1, a pressure sensing module 2, an elastic member 3 and a cutter head module 4, wherein a receiving cavity 11 is provided at the top of the shell 1, and the bottom of the cutter head module 4 is plugged into the receiving cavity 11, elastic support seats 12 are provided at both sides of the shell 1, and elastic member mounting portions 41 arranged opposite to the elastic support seats 12 are provided at both ends of the bottom of the cutter head module 4, and the two ends of the elastic member 3 are respectively abutted against the elastic support seat 12 and the elastic member mounting portion 41, and the shell 1 is further provided with a receiving groove 13 below the elastic support seat 12, and the pressure sensing module 2 is accommodated in the receiving groove 13. During operation, the cutter head module 4 is subjected to pressure, which causes the elastic member 3 to undergo elastic deformation, thereby causing the cutter head module 4 to float, thereby facilitating shaving in accordance with the facial contour. The elastic support seat 12 for supporting the elastic member 3 also undergoes elastic deformation under the compression deformation of the elastic member 3. The pressure sensing module 2 converts the deformation of the elastic support seat 12 into an electrical signal and transmits it to the circuit module of the shaver. After receiving the signal, the circuit module sends a prompt signal to remind the user of the current shaving pressure, thereby facilitating the user to adjust the shaving pressure appropriately, thereby improving shaving comfort and reducing skin damage.

[0027] The housing 1 comprises a first outer shell 14, an inner shell 15 and a second outer shell 16. The inner shell 15 covers the first outer shell 14 and then encloses the receiving chamber 11 on the top of the two. The elastic support seat 12 is arranged on both sides of the inner shell 15. The receiving groove 13 is arranged on the outer side of the inner shell 15. The second outer shell 16 covers the first outer shell 14 relatively to wrap the inner shell 15, effectively preventing external moisture and dust from contacting the inner shell 15, thereby protecting the components inside the shaver from corrosion and damage. In this embodiment, the elastic support seat 12 is integrally formed with the inner shell 15, which effectively reduces the assembly steps, and can enhance the structural stability of the inner shell 15 and extend the service life. In other embodiments, the elastic support seat 12 can be installed on the inner shell 15 as a separate component, and its installation method includes but is not limited to snap fixation, screw fixation, glue bonding and interference fit.

[0028] The elastic support seat 12 is made of resin material. The elastic support seat 12 made of resin material is not only easy to deform under force, which is convenient for the pressure sensing module 2 to accurately capture the deformation signal, but also has excellent elastic recovery, can absorb and disperse vibration during shaving, reduce the pressure of the cutter head on the skin, and improve the comfort and safety of shaving. In other embodiments, the elastic support seat 12 can also be made of easily deformable materials such as rubber. In order to further allow the pressure sensing module 2 to sense the pressure changes of the elastic support seat 12, the wall thickness range from the elastic support seat 12 to the top of the receiving groove 13 is 0.45mm to 0.55mm. Preferably, the wall thickness from the elastic support seat 12 to the top of the receiving groove 13 is 0.50mm. In other embodiments, the wall thickness from the elastic support seat 12 to the top of the receiving groove 13 may also be 0.45mm or 0.55mm.

[0029] The pressure sensing module 2 includes a signal connector 21 and at least two pressure sensors 22, the pressure sensors 22 are connected to the same end of the signal connector 21, and at least two of the pressure sensors 22 are respectively arranged corresponding to the elastic support seat 12; the housing 1 is also provided with a circuit module 17, and the other end of the signal connector 21 extends to the circuit module 17 and is connected to the circuit module 17. By providing at least two pressure sensors 22 respectively corresponding to the elastic support seat 12, the pressure on the cutter head module 4 at different positions can be sensed, thereby improving the test accuracy. The signal connector 21 is a flexible circuit board, which has good bendability and crease resistance, can be bent and folded at any angle, and is convenient for storage in the receiving groove 13 without affecting its performance. In another embodiment, the signal connector 21 can also be a rigid printed circuit board or other circuit board. After the pressure sensor 22 receives the deformation signal of the elastic support seat 12, the pressure sensor 22 transmits the signal to the circuit module 17 through the signal connector 21, and the circuit module 17 then sends other specified signals, such as light, vibration, sound, etc., to attract the attention of the user.

[0030] There are two pressure sensors 22, and the signal connector 21 is a "T"-shaped structure. The two pressure sensors 22 are respectively connected to the two ends of the top of the signal connector 21. The "T"-shaped signal connector 21 provides an efficient signal transmission channel for the two pressure sensors 22, reducing the loss and delay in the signal transmission process. In other embodiments, the signal connector 21 may also be an "I"-shaped structure, or a structure of other shapes.

[0031] Please also read Figure 3The receiving groove 13 includes a first receiving groove 131, a second receiving groove 132 and a third receiving groove 133 which are arranged in sequence from top to bottom. The first receiving groove 131, the second receiving groove 132 and the third receiving groove 133 are connected to each other. The first receiving groove 131 extends along the width direction of the shell 1. The pressure sensor 22 is received in the first receiving groove 131. The second receiving groove 132 extends along the length direction of the shell 1. The signal connector 21 is received in the second receiving groove 132. The circuit module 17 is received in the third receiving groove 133. Different receiving grooves are used to receive different components, which improves the convenience during installation. The shapes of the first receiving groove 131, the second receiving groove 132 and the third receiving groove 133 are respectively adapted to the shapes of the pressure sensor 22, the signal connector 21 and the circuit module 17, and are slightly larger than their outer dimensions to ensure the stability and smoothness of the signal.

[0032] The first receiving groove 131 includes two sensor receiving parts 1311 and a connecting part 1312. The two sensor receiving parts 1311 are respectively arranged at the two ends of the connecting part 1312. The two pressure sensors 22 are respectively accommodated in the sensor receiving parts 1311. The connecting part 1312 is arranged in the middle of the first receiving groove 131. The connecting part 1312 connects the sensor receiving part 1311 and the second receiving groove 132. The pressure sensor is a long strip structure. The sensor receiving part 1311 extends along the thickness direction of the shell 1, which is convenient for completely accommodating the long strip pressure sensor. The connecting part 1312 extends along the width direction of the shell 1, which is convenient for accommodating the connection section of the signal connector 21 and the pressure sensor 22, so that the signal connector 21 can be smoothly transitioned to the second receiving groove 132, thereby improving the convenience and stability of accommodation. Furthermore, the connecting portion 1312 separates the two sensor receiving portions 1311 , which helps to more accurately monitor the deformation of the corresponding elastic support seat 12 , thereby further improving the monitoring accuracy.

[0033] The shaver also includes a seal 5, which covers the notch of the receiving groove 13. This prevents external impurities, water vapor, etc. from affecting the pressure sensing module 2. The shape of the seal 5 is compatible with the shape of the receiving groove 13, which can not only further improve the sealing performance, but also eliminate the need for complex adjustments or corrections during assembly, thereby reducing the difficulty of assembly. The sealing method of fixing the seal 5 to the notch of the receiving groove 13 includes but is not limited to thermal melting, ultrasonic welding, rubber ring pressing, glue bonding and other sealing methods.

[0034] The sealing member 5 includes a cover plate 51 and a pressure strip 52. The cover plate 51 is covered on the receiving groove 13. The pressure strip 52 protrudes from the top of the cover plate 51 and extends in the direction close to the receiving groove 13. The pressure strip 52 presses the pressure sensing module 2 on the top of the receiving groove 13. The pressure sensor 22 is more closely attached to the elastic support seat 12, and the monitoring accuracy is further improved. In another embodiment, a pressing portion is provided in the receiving groove 13, which is used to press the pressure sensing module 2 to the top of the receiving groove 13, and the sealing member 5 only plays a sealing role. The circuit module 17 is provided with a press switch 171, and an elastic convex bump 511 is provided on the cover plate 51. The elastic convex bump 511 is arranged opposite to the switch 171, and the circuit module 17 can be opened and closed by pressing the elastic convex bump 511. In this embodiment, the elastic convex bump 511 is integrally formed with the cover plate 51, which is convenient for enhancing the sealing performance of the sealing member 5 and facilitating assembly. In another embodiment, the elastic convex bump 511 can be installed on the cover plate 51 as a separate component, and its installation methods include but are not limited to snap fixing, screw fixing, glue bonding, interference fit, hot melt, etc. In another embodiment, the switch 171 is a push-pull type, the cover plate 51 is provided with a strip hole, and the switch 171 protrudes from the strip hole.

[0035] Please also read Figure 4 The pressure strip 52 includes an extension portion 521 and a pressing portion 522. The extension portion 521 protrudes from the top of the cover plate 51 and extends toward the receiving groove 13. The pressing portion 522 is provided at the end of the extension portion 521 and extends toward the top of the receiving groove 13. In order to ensure the stability and smoothness of the signal, a certain gap must exist between the pressure strip 52 and the pressure sensor 22. Therefore, the pressure strip 52 is configured as the extension portion 521 and the pressing portion 522. The extension portion 521 extends the pressing portion 522 under the pressure sensor 22. The pressure sensor 22 is pressed only by the pressing portion 522, thereby reducing the contact area between the pressure strip 52 and the pressure sensor 22. Furthermore, the extension portion 521 is provided with a groove 5211, thereby further increasing the gap between the pressure strip 52 and the pressure sensor 22.

[0036] The elastic member 3 includes a spring 31, and a limiting column 121 is provided on the top of the elastic support seat 12, and the spring 31 is plugged into the limiting column 121. The spring 31 has a simple structure, which is convenient for realizing the floating of the cutter head module 4. The limiting column 121 can ensure that the spring 31 will not shake or fall off at will when subjected to external force, thereby maintaining its stable working state. In another embodiment, a limiting groove matching the shape of the spring 31 is provided on the top of the elastic support seat 12, and the spring 31 is plugged into the limiting groove. In another embodiment, the elastic member 3 can also be made of a rubber strip or other elastic materials.

[0037] Please also read Figure 5 , the spring 31 is fixed on the cutter head module 4, the elastic member mounting portion 41 is a plug-in column 411, the spring 31 is plugged into the plug-in column 411 by interference fit, and the spring 31 can be tightly fixed to the bottom end of the cutter head module 4 without other fixing structures, which simplifies the installation process, saves installation time and cost, and improves assembly efficiency. A guide portion is provided on the top of the plug-in column 411 to facilitate the plugging of the spring 31 with the plug-in column 411, thereby improving assembly efficiency. In another embodiment, the spring 31 can also be fixed to the bottom of the cutter head module 4 by screw fixing, welding fixing, and glue fixing. In another embodiment, the spring 31 can also be installed on the elastic support seat 12, and the spring 31 is plugged into the limiting column 121 by interference fit.

[0038] The cutter head module 4 includes a cutter head 42 and a drive motor 43. The end of the drive motor 43 away from its output end is plugged into the receiving cavity 11. The cutter head 42 is arranged at the output end of the drive motor 43. The elastic member mounting portion 41 is arranged at both ends of the bottom of the cutter head 42. The elastic member 3 is respectively located on both sides of the drive motor 43. The drive motor 43 is electrically connected to the circuit module 17. The receiving cavity 11 limits and fixes the drive motor 43, and then limits and fixes the entire cutter head module 4 on the top of the housing 1, and the structure is compact and stable.

[0039] The working process of the present application is as follows: the blade module 4 floats to deform the spring 31, and the deformation of the spring 31 causes the elastic support seat 12 in contact with it to deform. The pressure sensor 22 collects the deformation signal of the elastic support seat 12 and sends it to the circuit module 17 through the signal connector 21. The circuit module 17 has a threshold setting. When the deformation signal of the elastic support seat 12 exceeds the threshold, the circuit module 17 sends other signals to attract the user's attention.

[0040] To sum up, the present invention provides a shaver, in which the pressure sensing module 2 is arranged below the elastic support seat 12, and can monitor the deformation of the elastic support seat 12 in real time, and output a prompt signal in real time according to its deformation, so as to facilitate the user to adjust the shaving pressure and technique in time, thereby improving the safety factor and comfort during shaving.
