Description

Technical Field

[0001] This utility model relates to the technical field of razors, and in particular to a razor. Background Technology

[0002] Electric shavers use electricity to power the blades, quickly and effectively shaving facial hair. Compared to traditional shavers, electric shavers are convenient to operate, save time and effort, and are safe and comfortable. During the use of an electric shaver, in order to quickly and cleanly shave, users usually press the shaver's foil tightly against the skin, allowing the foil to penetrate deeper into the hair roots for a complete shave. However, due to excessive pressure, when the foil makes too strong contact with the skin, it can cause irritation and damage, not only affecting the user experience but also causing safety issues such as bleeding. Utility Model Content

[0003] The purpose of this application is to solve the above-mentioned problems by providing a razor that addresses the technical problem that users cannot apply appropriate pressure for shaving when using an electric razor.

[0004] To achieve the above objectives, this application provides a shaver, including a housing, a pressure sensing module, an elastic element, and a blade module. The top of the housing has a receiving cavity, and the bottom of the blade module is inserted into the receiving cavity. Elastic support seats are provided on both sides of the housing. The bottom ends of the blade module have elastic element mounting portions disposed opposite to the elastic support seats. The two ends of the elastic element abut against the elastic support seats and the elastic element mounting portions, respectively. The housing also has a receiving groove below the elastic support seats, and the pressure sensing module is received in the receiving groove.

[0005] Compared to existing technologies, the pressure sensing module of this utility model is located below the elastic support base, which can monitor the deformation of the elastic support base in real time and output prompt signals in real time according to its deformation, so that users can adjust the shaving pressure and technique in time, thereby improving the safety and comfort of shaving.

[0006] In one embodiment, the pressure sensing module includes a signal connector and at least two pressure sensors. The pressure sensors are connected to the same end of the signal connector, and each of the at least two pressure sensors is positioned corresponding to an elastic support. A circuit module is also provided on the housing, and the other end of the signal connector extends to and connects to the circuit module. By having at least two pressure sensors positioned corresponding to the elastic support, the pressure exerted on the cutter head module at different locations can be sensed, improving testing accuracy.

[0007] In one embodiment, the number of pressure sensors is two, and the signal connector is a "T" type structure, with the two pressure sensors respectively connected to the two ends of the top of the signal connector. The "T" type signal connector provides an efficient signal transmission channel for the two pressure sensors, reducing signal loss and delay during transmission.

[0008] In one embodiment, the receiving slot includes a first receiving slot, a second receiving slot, and a third receiving slot arranged sequentially from top to bottom. The first receiving slot, the second receiving slot, and the third receiving slot are interconnected. The first receiving slot extends along the width direction of the housing, and the pressure sensor is received in the first receiving slot. The second receiving slot extends along the length direction of the housing, and the signal connector is received in the second receiving slot. The circuit module is received in the third receiving slot. Different receiving slots are used to accommodate different components, improving the convenience of installation.

[0009] In one embodiment, the first receiving groove includes two sensor receiving portions and a connecting portion. The two sensor receiving portions are respectively disposed at both ends of the connecting portion, and the two pressure sensors are respectively housed in the sensor receiving portions. The connecting portion is disposed in the middle of the first receiving groove and connects the sensor receiving portions and the second receiving groove. The connecting portion separates the two sensor receiving portions, which helps to more accurately monitor the deformation of the corresponding elastic support, further improving accuracy.

[0010] In one embodiment, a seal is further included, which covers the opening of the receiving groove to prevent external impurities, moisture, etc., from affecting the pressure sensing module.

[0011] In one embodiment, the seal includes a cover plate and a pressure strip. The cover plate covers the receiving groove, and the pressure strip protrudes from the top of the cover plate and extends toward the receiving groove, pressing the pressure sensing module against the top of the receiving groove. This allows the pressure sensor to fit more closely to the elastic support, further improving monitoring accuracy.

[0012] In one embodiment, the pressure strip includes an extension and a clamping portion. The extension protrudes from the top of the cover plate and extends toward the receiving groove. The clamping portion is located at the end of the extension and extends toward the top of the receiving groove. This reduces the contact area between the pressure strip and the pressure sensing module, increases the gap, and ensures stable and smooth signal transmission.

[0013] In one embodiment, the elastic element includes a spring, and a limiting post is provided at the top of the elastic support, with the spring inserted into the limiting post. The spring has a simple structure, facilitating the floating of the cutter head module, and the limiting post prevents the spring from detaching from the elastic support.

[0014] In one embodiment, the elastic element mounting portion is a plug-in post, and the spring is interference-fitted into the plug-in post. This facilitates the installation of the spring at the bottom end of the cutter head module, improving assembly efficiency.

[0026] Please refer to the following: Figure 1 and Figure 2This embodiment provides a shaver, including a housing 1, a pressure sensing module 2, an elastic element 3, and a blade module 4. The housing 1 has a receiving cavity 11 at its top, and the bottom of the blade module 4 is inserted into the receiving cavity 11. The housing 1 has elastic support seats 12 on both sides. The bottom ends of the blade module 4 have elastic element mounting portions 41 that are opposite to the elastic support seats 12. The two ends of the elastic element 3 abut against the elastic support seats 12 and the elastic element mounting portions 41, respectively. The housing 1 also has a receiving groove 13 below the elastic support seats 12, and the pressure sensing module 2 is received in the receiving groove 13. During operation, the shaving head module 4 is subjected to pressure, which causes the elastic element 3 to deform elastically, thereby causing the shaving head module 4 to float, making it easier to shave in accordance with the contours of the face. The elastic support base 12, which supports the elastic element 3, also deforms elastically under the compression deformation of the elastic element 3. The pressure sensing module 2 converts the deformation of the elastic support base 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 inform the user of the current shaving pressure, so that the user can adjust the pressure appropriately, improve shaving comfort, and reduce skin damage.

[0027] The housing 1 includes 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, forming a receiving cavity 11 on top of both. An elastic support base 12 is located on both sides of the inner shell 15, and a receiving groove 13 is located on the outer surface of the inner shell 15. The second outer shell 16 covers the first outer shell 14, enclosing the inner shell 15 and effectively preventing external moisture and dust from contacting it, thereby protecting the internal components of the shaver from corrosion and damage. In this embodiment, the elastic support base 12 is integrally formed with the inner shell 15, effectively reducing assembly steps and enhancing the structural stability of the inner shell 15, thus extending its service life. In another embodiment, the elastic support base 12 can be installed as a separate component on the inner shell 15, and its installation methods include, but are not limited to, snap-fit ​​fixing, screw fixing, glue bonding, and interference fit.

[0028] The elastic support base 12 is made of resin material. The resin material of the elastic support base 12 not only allows for easy deformation under stress, facilitating the pressure sensing module 2 to accurately capture deformation signals, but also possesses excellent elastic recovery, enabling it to absorb and disperse vibrations during shaving, reducing pressure on the skin from the shaving head and improving shaving comfort and safety. In another embodiment, the elastic support base 12 can also be made of easily deformable materials such as rubber. To further enable the pressure sensing module 2 to detect pressure changes in the elastic support base 12, the wall thickness of the elastic support base 12 to the top of the receiving groove 13 ranges from 0.45mm to 0.55mm. Preferably, the wall thickness of the elastic support base 12 to the top of the receiving groove 13 is 0.50mm. In another embodiment, the wall thickness of the elastic support base 12 to the top of the receiving groove 13 can 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 the at least two pressure sensors 22 are respectively positioned corresponding to the elastic support base 12. A circuit module 17 is also provided on the housing 1, and the other end of the signal connector 21 extends to and connects to the circuit module 17. By having at least two pressure sensors 22 respectively positioned corresponding to the elastic support base 12, the pressure on the blade module 4 at different positions can be sensed, improving testing accuracy. The signal connector 21 is a flexible circuit board with good bending and crease resistance, allowing it to be bent and folded at any angle, facilitating its storage in the receiving slot 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 receiving a deformation signal from the elastic support base 12, the pressure sensor 22 transmits this signal to the circuit module 17 through the signal connector 21. The circuit module 17 then sends other specified signals, such as light, vibration, or sound, to attract the user's attention.

[0030] The number of pressure sensors 22 is two, and the signal connector 21 has a "T" shape, with the two pressure sensors 22 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 signal loss and delay during transmission. In another embodiment, the signal connector 21 can also be an "I" shape or other shapes.

[0031] Please refer to the following: Figure 3The receiving slot 13 includes a first receiving slot 131, a second receiving slot 132, and a third receiving slot 133 arranged sequentially from top to bottom. The first receiving slot 131, the second receiving slot 132, and the third receiving slot 133 are interconnected. The first receiving slot 131 extends along the width direction of the housing 1, and the pressure sensor 22 is received in the first receiving slot 131. The second receiving slot 132 extends along the length direction of the housing 1, the signal connector 21 is received in the second receiving slot 132, and the circuit module 17 is received in the third receiving slot 133. Different receiving slots are used to accommodate different components, improving the convenience of installation. The shapes of the first receiving slot 131, the second receiving slot 132, and the third receiving slot 133 are respectively adapted to the external shapes of the pressure sensor 22, the signal connector 21, and the circuit module 17, and are all slightly larger than their external dimensions to ensure stable and smooth signal transmission.

[0032] The first receiving slot 131 includes two sensor receiving portions 1311 and a connecting portion 1312. The two sensor receiving portions 1311 are respectively located at both ends of the connecting portion 1312, and the two pressure sensors 22 are respectively received in the sensor receiving portions 1311. The connecting portion 1312 is located in the middle of the first receiving slot 131 and connects the sensor receiving portions 1311 and the second receiving slot 132. The pressure sensor has an elongated structure. The sensor receiving portion 1311 extends along the thickness direction of the housing 1 to facilitate the complete reception of the elongated pressure sensor. The connecting portion 1312 extends along the width direction of the housing 1 to facilitate the reception of the connection section of the signal connector 21 and the pressure sensor 22, so that the signal connector 21 can be smoothly received into the second receiving slot 132, improving the convenience and stability of reception. Furthermore, the connecting portion 1312 separates the two sensor receiving portions 1311, which helps to monitor the deformation of the corresponding elastic support 12 more accurately and further improves the monitoring accuracy.

[0033] The shaver also includes a sealing element 5, which covers the opening of the receiving groove 13. This prevents external impurities, moisture, etc., from affecting the pressure sensing module 2. The shape of the sealing element 5 is adapted to the shape of the receiving groove 13, which not only further improves the sealing performance but also eliminates the need for complex adjustments or corrections during assembly, thereby reducing assembly difficulty. The sealing element 5 can be fixed to the opening of the receiving groove 13 by methods including but not limited to heat melting, ultrasonic welding, rubber ring pressing, and adhesive bonding.

[0034] The sealing element 5 includes a cover plate 51 and a pressure strip 52. The cover plate 51 covers the receiving groove 13, and the pressure strip 52 protrudes from the top of the cover plate 51 and extends towards the receiving groove 13. The pressure strip 52 presses the pressure sensing module 2 against the top of the receiving groove 13, making the pressure sensor 22 fit more closely to the elastic support 12 and further improving the monitoring accuracy. In another embodiment, the receiving groove 13 is provided with a pressing part for pressing the pressure sensing module 2 against the top of the receiving groove 13, and the sealing element 5 only serves a sealing function. The circuit module 17 is provided with a push-button switch 171, and the cover plate 51 is provided with an elastic protrusion 511. The elastic protrusion 511 is disposed opposite to the switch 171, and the circuit module 17 can be opened and closed by pressing the elastic protrusion 511. In this embodiment, the elastic protrusion 511 and the cover plate 51 are integrally formed, which facilitates the sealing performance of the sealing element 5 and is convenient for assembly. In another embodiment, the elastic protrusion 511 can be installed as a separate component on the cover plate 51, and the installation method includes, but is not limited to, snap-fit ​​fixing, screw fixing, glue bonding, interference fit, heat fusion, and other installation methods. 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 refer to the following: Figure 4 The pressure strip 52 includes an extension 521 and a pressing part 522. The extension 521 protrudes from the top of the cover plate 51 and extends towards the receiving groove 13. The pressing part 522 is located at the end of the extension 521 and extends towards the top of the receiving groove 13. To ensure stable and smooth signal transmission, a certain gap is required between the pressure strip 52 and the pressure sensor 22. Therefore, the pressure strip 52 is configured with the extension 521 and the pressing part 522. The extension 521 extends the pressing part 522 below the pressure sensor 22, and only the pressing part 522 presses against the pressure sensor 22, reducing the contact area between the pressure strip 52 and the pressure sensor 22. Furthermore, the extension 521 has a groove 5211 to further increase the gap between the pressure strip 52 and the pressure sensor 22.

[0036] The elastic element 3 includes a spring 31, and a limiting post 121 is provided on the top of the elastic support base 12, into which the spring 31 is inserted. The spring 31 has a simple structure, which facilitates the floating of the cutter head module 4. The limiting post 121 ensures that the spring 31 will not shake or fall off when subjected to external force, thus maintaining its stable working state. In another embodiment, the top of the elastic support base 12 is provided with a limiting groove that matches the shape of the spring 31, into which the spring 31 is inserted. In another embodiment, the elastic element 3 can also be made of rubber strip or other elastic material.

[0037] Please refer to the following: Figure 5 The spring 31 is fixed to the cutter head module 4. The elastic element mounting part 41 is a plug-in post 411. The spring 31 is interference-fitted into the plug-in post 411, which allows the spring 31 to be tightly fixed to the bottom end of the cutter head module 4 without the need for other fixing structures. This simplifies the installation process, saves installation time and cost, and improves assembly efficiency. The top of the plug-in post 411 is provided with a guide part to facilitate the insertion of the spring 31 into the plug-in post 411, improving assembly efficiency. In another embodiment, the spring 31 can also be fixed to the bottom of the cutter head module 4 by means of screw fixing, welding fixing, or glue fixing. In another embodiment, the spring 31 can also be mounted on the elastic support base 12, and the spring 31 is interference-fitted into the limiting post 121.

[0038] The cutter head module 4 includes a cutter head 42 and a drive motor 43. One end of the drive motor 43, away from its output end, is inserted into the receiving cavity 11. The cutter head 42 is located at the output end of the drive motor 43. Elastic member mounting portions 41 are located at both ends of the bottom of the cutter head 42. Elastic members 3 are 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, thereby limiting and fixing the entire cutter head module 4 to the top of the housing 1, resulting in a compact and stable structure.

[0039] The working process of this application is as follows: the floating of the cutter head module 4 causes the spring 31 to deform, 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] In summary, the shaver provided by this utility model has a pressure sensing module 2 located below the elastic support base 12, which can monitor the deformation of the elastic support base 12 in real time and output prompt signals in real time according to its deformation, so that the user can adjust the shaving pressure and technique in time, thereby improving the safety and comfort of shaving.

[0041] The specific examples described above further illustrate the purpose, technical solution, and beneficial effects of this application. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model.
