Description

Technical Field

[0001] This invention relates to the field of shaver technology, and more specifically to a multifunctional shaver capable of automatically identifying the type of shaver head. Background Technology

[0002] Hair shavers are generally used to remove body hair. A razor is a type of hair shaver, typically used for trimming beards; other types include nose hair trimmers and body hair trimmers. Most common hair shavers have a single head, limiting their use to one application. To expand their applications, multi-head hair shavers have emerged. These typically include a main handle and detachable heads mounted on the handle head. These shavers have multiple detachable heads, allowing for flexible use in various situations and have become increasingly popular.

[0003] When the blades mounted on the head of the main unit handle require electric drive, different blades often require different drive voltages. Therefore, how to provide a more convenient and accurate voltage matching for different blades becomes a problem that needs to be solved. Chinese patent document CN209158468U discloses a personal care device for performing personal care operations on an object. The personal care device includes a handheld base body, a drive unit, a sensor, and a control unit. The drive unit is used to receive and drive interchangeable processing heads to perform personal care operations. The drive unit includes a drive shaft and a motor assembly. The drive shaft receives the interchangeable processing heads, and the motor assembly rotates and / or applies vibrational motion to the drive shaft. The sensor measures the amount of current obtained from the motor assembly while the drive unit is operated. The control unit is operatively connected to the sensor and the drive unit and configured to control the drive unit. The sensor is configured to measure the motor current at a predetermined measurement time after the drive unit is activated, and the control unit is configured to identify individual processing heads mounted on the drive unit by comparing the motor current measured at the predetermined measurement time with at least one predetermined current threshold.

[0004] The technical solution in the aforementioned patent document identifies the processing head by detecting the current value of the processing head installed on the handheld base body and provides a matching voltage to the motor to drive the processing head to work. However, the above technical solution is relatively complicated, and once the measurement of the current value is affected, the recognition effect of the processing head will be affected.

[0005] Therefore, how to design a simple, direct solution that can quickly identify the type of cutting head and provide a matching voltage to the motor to drive the cutting head to work normally is a technical problem that has not yet been solved in the existing technology. Summary of the Invention

[0006] Therefore, the technical problem to be solved by the present invention is to overcome the technical defects of the existing technology in which the solution for identifying the type of razor head is complicated and the identification of the razor head is affected once the current value measurement is affected. The present invention provides a shaver that can easily and quickly identify the type of razor head without detecting the current value, and thus provide a matching current to the motor to drive the razor head to work normally.

When the first chip and the second chip are in contact, the recognizer can recognize the code, thereby identifying the cutting head type.

[0033] The technical solution provided by this invention has the following advantages:

[0034] 1. The present invention provides a multi-functional shaver capable of automatically identifying the type of shaver head, comprising a main handle, a drive motor, a shaver head, a power supply, a power switch, a first identification structure, a second identification structure, and a circuit board structure; wherein the drive motor has a drive shaft, the shaver head is mounted at the end of the main handle and can be driven by the drive shaft, the power switch supplies power to the drive motor by controlling the on / off state of the power supply, the first identification structure is disposed on the main handle, the second identification structure is disposed on the shaver head, and the circuit board structure has circuits that supply different voltages to the drive motor.

[0035] In use, according to the user's needs, different functional cutter heads are selected and installed on the main unit handle. The first identification structure on the main unit handle and the second identification structure on the cutter head interact to identify the type of cutter head installed. Then, the circuit on the circuit board structure with a voltage compatible with the identified cutter head type is directly connected or controlled by the chip. When the power switch is turned on, the power supply provides the drive motor with a voltage compatible with the cutter head type through the circuit connected on the circuit board structure. The drive motor works to drive the drive shaft to rotate, thereby driving the cutter head to work.

[0036] The multi-functional shaver of the present invention can automatically identify the type of shaver head. It can identify the type of shaver head simply and quickly through the interaction of the first identification structure and the second identification structure without detecting the current value. The circuit board structure is then used to allocate a circuit with a matching voltage to the drive motor to drive the shaver head to work normally.

[0037] 2. The multi-functional shaver of the present invention, capable of automatically identifying the type of shaver head, has a first identification structure as a micro switch mounted on the main handle and a second identification structure as a rib mounted on the shaver head. After the shaver head is installed on the main handle, the rib on the shaver head presses against the corresponding micro switch on the main handle. When the micro switch is pressed, the corresponding circuit on the circuit board is activated. Since there are multiple micro switches on the main handle in different positions, and the rib is positioned differently on different types of shavers, when a micro switch in a certain position is pressed, it indicates that a specific type of shaver head is currently installed. In this way, the type of shaver head can be identified simply and quickly, and the rib presses against the micro switch to activate a specific circuit on the circuit board, providing a circuit with a compatible voltage to the drive motor to drive the shaver head to work normally.

[0038] 3. The multi-functional shaver of the present invention can automatically identify the type of shaver head. At least two ribs can be installed on certain shaver heads. When that type of shaver head is installed, at least two ribs can simultaneously press multiple microswitches. When multiple microswitches are pressed simultaneously, it indicates that a specific type of shaver head is currently installed. By pressing multiple microswitches, a specific circuit on the circuit board structure can be connected. When the power supply provides power to the shaver head through this circuit, it can output a voltage compatible with the shaver head type to drive the shaver head to work normally. The multi-functional shaver of the present invention can determine the shaver head type by using multiple ribs simultaneously pressing multiple microswitches and automatically connect a circuit that is compatible with the voltage of that type of shaver head.

[0039] 4. The multi-functional shaver of the present invention can automatically identify the type of shaver head. The micro switch is located at the end of the main handle, and the rib is located inside the mounting cover of the shaver head. When the shaver head is mounted at the end of the main handle through the mounting cover, the rib can be opposite to the micro switch, thereby pressing the micro switch to connect a specific circuit.

[0040] 5. The multi-functional shaver of the present invention can automatically identify the type of shaver head. The end of the main handle is provided with a positioning groove and / or a positioning protrusion, and the inner wall of the mounting cover of the shaver head is provided with a positioning protrusion and / or a positioning groove. When the shaver head is mounted on the main handle through the mounting cover, the positioning protrusion and the positioning groove are matched and inserted to realize the positioning of the shaver head, so that the rib can be accurately pressed onto the micro switch and avoid misalignment.

[0041] 6. The multi-functional shaver of the present invention can automatically identify the type of shaver head. The end of the main handle is provided with a head magnet, and the corresponding position of the shaver head is provided with a shaver head magnet. When the shaver head is installed at the end of the main handle, the head magnet and the shaver head magnet attract each other. The mutual attraction of the magnets makes the installation between the main handle and the shaver head more secure, and also allows the shaver to press the micro switch with greater force, avoiding the situation where the micro switch cannot be pressed in place due to insufficient pressure.

[0042] 7. The multi-functional shaver of the present invention, capable of automatically identifying the type of shaver head, comprises a first identification structure consisting of an infrared transmitter and an infrared receiver mounted on the main handle, and a second identification structure consisting of a groove on the shaver head. The depth of the groove varies depending on the type of shaver head. The infrared transmitter emits an infrared signal toward the groove, which is reflected by the groove and received by the infrared receiver. The intensity of the infrared light decreases significantly with the distance of propagation. The infrared receiver determines the type of shaver head based on the strength of the received infrared signal and then transmits the signal to a chip. The chip controls the circuit board structure to connect a specific circuit, and the power switch controls the power supply to provide a voltage compatible with the type of shaver head to the drive motor through the aforementioned specific circuit, thereby driving the shaver head to work normally.

[0043] 8. The multi-functional shaver of the present invention, capable of automatically identifying the type of shaver head, has a first identification structure consisting of a first chip disposed on the main handle and a second identification structure consisting of a second chip disposed on the shaver head. When the shaver head is installed on the main handle, the first chip and the second chip are in contact with each other, thus identifying the type of shaver head. After identifying the type of shaver head, the first chip or the second chip sends a signal to a chip mounted on a circuit board structure. The chip controls the circuit board structure to connect a specific circuit, and the power switch controls the power supply to provide a voltage compatible with the type of shaver head to the drive motor through the aforementioned specific circuit, so as to drive the shaver head to work normally.

[0044] 9. The present invention provides a multi-functional shaver capable of automatically identifying the type of shaver head. The second chip stores a code corresponding to the type of shaver head, and the first chip is equipped with a recognizer. When the first chip and the second chip are in contact, the recognizer identifies the code, thereby identifying the type of shaver head. Then, a signal is sent to a chip mounted on the circuit board structure, which controls the circuit board structure to connect a specific circuit. Attached Figure Description

[0064] The present application will now be described in detail with reference to the accompanying drawings and embodiments. Example 1

[0065] This embodiment provides a multi-functional shaver capable of automatically identifying the type of shaver head, such as... Figure 1-10As shown, it includes: a main handle 1, a drive motor 2, a blade 3, a power supply 4, a power switch 5, a first identification structure, a second identification structure, and a circuit board structure 6; wherein the main handle 1 has an end for mounting the blade 3; the drive motor 2 is installed inside the main handle 1 and has a drive shaft 21 extending from the end of the main handle 1; there is at least one blade 3, which can be detachably mounted on the end of the main handle 1 and can be driven by the drive shaft 21 after being assembled with it; the power supply 4 is used to supply power to the drive motor 2; the power switch 5 is connected in series with the power supply 4 to supply power to the drive motor 2. The circuit powering the drive motor 2 also includes a first identification structure and a second identification structure, wherein the first identification structure is disposed on the main handle 1; the second identification structure is disposed on the blade head 3; the circuit board structure 6 has circuits that supply different voltages to the drive motor 2; after the blade head 3 is installed on the main handle 1, the first identification structure and the second identification structure interact to identify the type of the blade head 3, and at the same time connect the voltage circuit on the circuit board structure 6 that is compatible with the type of the blade head 3; after the power switch 5 is turned on, it provides the blade head 3 with the appropriate voltage.

[0066] In use, according to the user's needs, different functional blade heads 3 are selected and installed on the main unit handle 1. The first identification structure on the main unit handle 1 and the second identification structure on the blade head 3 interact to identify the type of the installed blade head 3. Then, the circuit on the circuit board structure 6 with a voltage compatible with the identified blade head 3 type is directly connected or controlled by the chip. When the power switch 5 is turned on, the power supply 4 provides the drive motor 2 with a voltage compatible with the blade head 3 type through the circuit connected on the circuit board structure 6. The drive motor 2 drives the drive shaft 21 to rotate, thereby driving the blade head 3 to work. This embodiment of a multi-functional shaver that can automatically identify the type of blade head does not require current detection. It can simply and quickly identify the type of blade head 3 through the interaction of the first and second identification structures, and allocate a circuit with a compatible voltage to the drive motor 2 through the circuit board structure 6 to drive the blade head 3 to work normally.

[0067] like Figure 5 and 6As shown, the first identification structure is a micro switch 11 disposed on the main handle 1. At least one micro switch 11 is provided on the main handle 1, and the positions of the micro switches 11 are different. The second identification structure is a rib 31 disposed on the cutter head 3. The rib 31 is disposed in different positions on different types of cutter heads 3. When different types of cutter heads 3 are installed on the main handle 1, the rib 31 disposed on the cutter head 3 presses down on the corresponding position of the micro switch 11. After the micro switch 11 is pressed down, the circuit on the circuit board structure 6 used to supply the corresponding voltage to the corresponding type of cutter head 3 is turned on. In this way, the type of cutter head 3 can be identified simply and quickly, and the specific circuit on the circuit board structure 6 can be turned on by the rib 31 pressing down the micro switch 11 to provide a circuit with a matching voltage to the drive motor 2 so as to drive the cutter head 3 to work normally.

[0068] At least two of the reinforcing ribs 31 are provided on the blade head 3. When the blade head 3 is installed on the main handle 1, at least two reinforcing ribs 31 simultaneously press at least two microswitches, connecting the circuit on the circuit board structure 6 for supplying the corresponding voltage to the blade head 3 of the corresponding type. When installing a certain type of blade head 3, at least two reinforcing ribs 31 can simultaneously press multiple microswitches 11. When multiple microswitches 11 are pressed simultaneously, it indicates that a certain specific type of blade head 3 is currently installed. By pressing multiple microswitches 11, a specific circuit on the circuit board structure 6 can be connected. When the power supply 4 supplies power to the blade head 3 through this circuit, it can output a voltage that matches the type of blade head 3 to drive the blade head 3 to work normally. In this embodiment, the multi-functional shaver can use multiple reinforcing ribs 2 to simultaneously press multiple microswitches 11 to determine the type of blade head 3 and automatically connect the circuit that is compatible with the voltage of that type of blade head 3.

[0069] The micro switch 11 is disposed at the end of the main handle 1; the rib 31 is disposed on the inner wall of the mounting cover 32 of the blade head; when the blade head 3 is mounted at the end of the main handle 1 through the mounting cover 32, the rib 31 can be opposite to the micro switch 11, thereby pressing the micro switch 11 to connect a specific circuit.

[0070] Specifically in this embodiment, such as Figure 6 The micro switch 11 has three parts, with the words "shaver", "nose hair trimmer" and "U-knife" written on the corresponding positions respectively;

[0071] When the shaver head 3 is installed on the main handle 1, the rib 31 inside the shaver head 3 will press on the micro switch 11 with the word "shaver" written on it, triggering it and connecting the circuit on the circuit board structure 6 for powering the shaver head 3. At this time, the voltage is adjusted to, for example, 3.5V, and the drive motor 2 has the highest speed, for example, 9000RPM.

[0072] When the nose hair trimmer head 3 is installed on the main handle 1, the rib 31 inside the nose hair trimmer head 3 will press on the micro switch 11 with the word "nose hair trimmer" written on it, triggering it and connecting the circuit on the circuit board structure 6 for powering the nose hair trimmer head 3. At this time, the voltage is adjusted to, for example, 3.1V, and the speed of the drive motor 2 is low, for example, 7000RPM.

[0073] When the U-shaped blade head 3 is installed on the main handle 1, the rib 31 inside the U-shaped blade head 3 will press against the micro switch 11 marked with the word "U-blade", triggering it and connecting the circuit on the circuit board structure 6 for powering the U-shaped blade head 3. At this time, the voltage is adjusted to, for example, 3.3V, and the speed of the drive motor 2 is relatively high, for example, 7500RPM.

[0074] As a variation, two or three microswitches 11 can be pressed simultaneously, connecting the circuit on the circuit board structure 6 to power the type of cutter head, outputting a voltage compatible with its type to drive it to work normally.

[0075] like Figure 1 As shown, on the front of the main handle 1, above the power switch 5, there are indicator lights. From top to bottom, they are a U-shaped indicator light for the U-shaped blade, a shaver indicator light with lines inside a square, a diamond-shaped indicator light for the nose hair trimmer, and a charging indicator light with a battery symbol. When the U-shaped blade head 3 is installed on the main handle 1, the U-shaped blade indicator light is on, and the shaver indicator light, nose hair trimmer indicator light, and charging indicator light are off. When a different blade head 3 is replaced, the indicator light indicating that type of blade head is on, and the other lights are off. The charging indicator light is only on when charging.

[0076] Preferred, such as Figure 3 and Figure 5 As shown, it also includes a positioning structure, which includes a positioning groove 12 and a positioning protrusion 13 disposed on the end of the main handle 1, and a positioning protrusion 13 and a positioning groove 12 disposed on the inner wall of the mounting cover 32. When the blade 3 is mounted on the main handle 1 through the mounting cover 32, the positioning protrusion 13 and the positioning groove 12 are matched and inserted to realize the positioning of the blade 3, so that the rib 31 can be accurately pressed onto the micro switch 11 to avoid misalignment.

[0077] like Figure 9-10As shown, a head magnet 14 is provided at the end of the main handle 1, and a blade magnet 33 is provided at the corresponding position of the blade 3. When the blade 3 is installed on the main handle 1, the head magnet 14 and the blade magnet 33 attract each other, so that the rib 31 can press on the micro switch 11 with greater force. The mutual attraction of the magnets makes the installation between the main handle 1 and the blade 3 more secure, and also allows the rib 31 to press on the micro switch 11 with greater force, avoiding the situation where the micro switch 11 cannot be pressed in place due to insufficient pressure.

[0078] The head magnet 14 is ring-shaped and is sleeved around the drive shaft 21. Example 2

[0079] This embodiment provides a multi-functional shaver capable of automatically identifying the type of shaver head. It is a variation based on Embodiment 1, such as... Figure 11-12 As shown, the first identification structure consists of an infrared transmitter 7 and an infrared receiver 8 disposed on the main handle 1; the second identification structure consists of a groove 34 disposed on the blade head 3. The groove 34 on different types of blade heads 3 has different depths. The position of the groove 34 is opposite to the infrared transmitter 7 and the infrared receiver 8. It can receive and reflect infrared signals from the infrared transmitter 7. The infrared receiver 8 can receive infrared signals reflected from the groove 34 and send corresponding signals to the chip disposed on the circuit board structure 6. The chip connects the circuit on the circuit board structure 6 for supplying the corresponding voltage to the corresponding type of blade head 3 according to the signal.

[0080] In this embodiment, considering that the intensity of infrared light decreases significantly with the distance of propagation, the infrared receiver 8 determines the type of the cutter head 3 based on the strength of the received infrared signal, and then transmits the signal to the chip. The chip controls the circuit board structure 6 to connect a specific circuit, and the power switch 5 controls the power supply 4 to supply the drive motor 2 with a voltage that is compatible with the type of cutter head 3 through the aforementioned specific circuit, so as to drive the cutter head 3 to work normally. Example 3

[0081] This embodiment provides a multi-functional shaver capable of automatically identifying the type of shaver head. It is a variation based on Embodiment 1, such as... Figure 13-14As shown, the first identification structure is a first chip 9 disposed on the main handle 1; the second identification structure is a second chip 10 disposed on the blade head 3, the second chip 10 being positioned vertically opposite to the first chip 9; after the blade head 3 is installed on the main handle 1, the first chip 9 and the second chip 10 come into contact, the first chip 9 identifies the type of the blade head 3 and sends a corresponding signal to a chip disposed on the circuit board structure 6, the chip activating the circuit on the circuit board structure 6 for supplying the corresponding voltage to the corresponding type of blade head 3 according to the signal.

[0082] Specifically, the second chip 10 installed on different cutter heads 3 stores the code corresponding to the type of cutter head 3. The first chip 9 is equipped with an identifier. When the first chip 9 and the second chip 10 are in contact, the identifier can identify the code, thereby identifying the type of cutter head. After identifying the type of cutter head, the first chip 9 or the second chip 10 sends a signal to the chip installed on the circuit board structure 6. The chip controls the circuit board structure 6 to turn on a specific circuit. The power switch 5 controls the power supply 4 to supply the drive motor 2 with a voltage that is compatible with the type of cutter head 3 through the aforementioned specific circuit, so as to drive the cutter head 3 to work normally.

[0083] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this innovative technical solution.
