Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to an induction shaver. Background Technology

[0002] The emergence of sensor-operated shavers represents a significant advancement in electric shaver technology. It not only enhances ease of use but also provides a completely new user experience in terms of safety, battery life, and cleaning / maintenance. Sensor-operated shavers feature touch-to-start and skin-removal automatic stop functions. When the shaver head lightly touches the skin, it instantly starts shaving and automatically stops when the shaver leaves the skin.

[0003] To achieve the above functions, current sensor-type shavers use a single-channel capacitive sensor. When human skin comes into contact with the sensing module on the shaver mesh, the shaver detects an increase in signal and then starts the shaver motor.

[0004] However, the sensor module on the shaver's mesh is prone to malfunctions when exposed to liquids such as water. To prevent malfunctions in sensor-operated shavers, current manufacturers detect water ingress by checking the resistance generated between the grounding wire and the sensor after the grounding wire has been submerged in water. However, the grounding wire is usually located inside the charging port. If water bubbles are present in the narrow charging port, water cannot easily enter, causing the shaver to fail to stop automatically. Utility Model Content

[0005] Therefore, it is necessary to address the aforementioned technical problems by providing a sensor-type shaver, including a secondary sensor module, a motor, and a main control board; wherein,

[0006] The secondary sensing module is located inside the machine body and is connected to the main control board;

[0007] The main control board is connected to the motor;

[0008] When the sensor-operated shaver is in the activated state, the main control board controls the motor to shut down when it detects a signal change from the secondary sensor module.

[0009] As an optional implementation, the sensor-operated shaver further includes a foil assembly, which comprises a foil and a main sensing module; wherein,

[0010] The main sensing module is mounted on the blade mesh and connected to the main control board;

[0011] When the sensor-operated shaver is in a stopped state, the main control board controls the motor to start when it detects a signal change from the main sensor module.

[0012] As an optional implementation, the secondary sensing module is in insulating contact with the blade mesh assembly.

[0018] The capacitance detection module is connected to the main sensing module and the auxiliary sensing module, and is used to detect the signals of the main sensing module and the auxiliary sensing module;

[0023] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

[0024] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0025] Figure 1 This is a schematic diagram of the structure of an induction shaver provided in an embodiment of this application;

[0026] Figure 2 This is a schematic diagram of the structure of a blade mesh assembly provided in an embodiment of this application;

[0027] Figure 3 This is a schematic diagram of another induction shaver provided in an embodiment of this application. Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0029] The following will describe in detail an inductive shaver provided in the embodiments of this application, with reference to specific implementation methods. Figure 1 This is a schematic diagram of the structure of an induction shaver provided in an embodiment of this application, as shown below. Figure 1 As shown, the sensor-type shaver includes a secondary sensor module 110, a motor (not shown in the figure), and a main control board (not shown in the figure). Among them,

[0030] The secondary sensing module 110 is located inside the machine body and is connected to the main control board 130.

[0031] The main control board is connected to the motor.

[0032] When the sensor-operated shaver is in the activated state, the main control board controls the motor to shut down when it detects a signal change in the secondary sensor module 110.

[0033] In implementation, the secondary sensor module 110 is located inside the shaver body and connected to the main control board via wires or other connections. The main control board is further connected to the motor, which controls the operation of the shaver blades. When the shaver is in the start-up state, the secondary sensor module is responsible for monitoring changes in the environment. If a signal change is detected, such as a change in humidity or water intrusion, the main control board will respond to this change and immediately control the motor to shut down, thereby preventing the shaver from continuing to operate under unsafe conditions.

[0034] Preferably, the secondary sensing module 110 can be a sensor based on capacitive sensing technology, or it can be a photoelectric sensor or a microwave sensor. These sensors can monitor changes in the internal environment of the shaver in real time, and perform particularly well in humid environments. When the shaver is started, if the user accidentally immerses it in water, water enters the machine body. The secondary sensing module detects changes in capacitance or interference in the photoelectric signal, and the main control board quickly senses this and issues a command to immediately stop the motor. Compared to traditional mechanical shavers, this invention greatly improves safety, especially in humid environments such as bathrooms, better preventing accidents.

[0035] As an optional implementation method, Figure 2 This is a schematic diagram of the structure of a blade mesh assembly provided in an embodiment of this application, as shown below. Figure 1 and 2 As shown, the sensor-operated shaver also includes a foil assembly 210, which comprises a foil 2101 and a main sensing module 2102. Among them,

[0036] The main sensing module 2102 is mounted on the blade mesh 2101 and connected to the main control board 130.

[0037] When the sensor shaver is in a stopped state, the main control board 130 controls the motor 120 to start when it detects a signal change in the main sensor module 2102.

[0038] In practice, sensor-operated shavers, in addition to the secondary sensor module, also include a foil assembly. For example... Figure 2 As shown, the shaver assembly consists of a shaver foil and a main sensing module. The main sensing module 2102 is connected to the shaver foil via electrode plates, allowing it to sense changes in the environment around the shaver foil 2101 and connect to the main control board. When the shaver is stationary, if the main control board detects a change in the signal from the main sensing module, such as when the user holds the shaver or touches the shaver foil, the main control board will control the motor to start, thus putting the shaver into working mode. The collaborative work of the shaver foil assembly and the main sensing module allows the shaver to respond to user operations with high sensitivity. The main sensing module can detect the user's intention by sensing the contact between the user's fingers or skin and the shaver foil. Once the main control board receives these signal changes, it will control the motor to start, thereby achieving intelligent operation of the shaver. This design allows the shaver to not only rely on manual switches but also react to user behavior, providing a more intelligent and convenient user experience.

[0039] As an optional implementation method, Figure 3 This is a schematic diagram of another induction shaver provided in an embodiment of this application, as shown below. Figure 1 and Figure 3As shown, the secondary sensing module 110 is in insulated contact with the knife net assembly 210.

[0040] In practice, the auxiliary sensing module 110 and the knife net 2101 are separated by insulating material or set at a preset distance to ensure that there is no conductive contact between them.

[0041] As an optional implementation, the main sensing module 2102 and the blade net 2101 are connected via a conductive element 2103.

[0042] As an optional implementation, the conductive element 2103 is a conductive spring pin.

[0043] In implementation, such as Figure 2 As shown, the conductive spring needle has shockproof capability and conductivity, making it suitable for the working environment of a shaver.

[0044] As an optional implementation, the secondary sensing module 110 is located inside the body in the lower region near the blade net.

[0045] When water enters the machine body through the blade mesh, the main control board will shut down the motor when it detects a change in the signal from the secondary sensing module.

[0046] In implementation, such as Figure 3 As shown, the secondary sensor module 110 is installed inside the shaver body, located below the foil. This design ensures that when water enters the shaver through the foil, it first contacts the secondary sensor module 110. The secondary sensor module 110 detects the presence of water and generates a signal change. Upon receiving the signal, the main control board immediately shuts off the motor, effectively preventing the shaver from accidentally starting or malfunctioning in water.

[0047] As an optional implementation, the main control board includes a capacitor detection module and a motor control module.

[0048] in,

[0049] The capacitance detection module connects the main sensing module and the auxiliary sensing module, and is used to detect the signals from the main sensing module and the auxiliary sensing module.

[0050] The motor control module is connected to the motor and is used to control the motor to start based on the signal changes of the main sensing module, and to control the motor to stop based on the signal changes of the auxiliary sensing module.

[0051] In implementation, the main control board design includes a capacitance detection module and a motor control module. The capacitance detection module connects to the main and auxiliary sensing modules to detect changes in their signals. The motor control module uses these signals to control the motor's start and stop. When the main sensing module signal changes, the motor control module starts the motor. When the auxiliary sensing module signal changes, the motor control module stops the motor.

[0052] As an optional implementation, the main sensing module is a capacitive sensing electrode, a photoelectric sensor, or a low-power microwave sensor.

[0053] In implementation, the main sensing module can employ various sensor types, including capacitive sensing electrodes, photoelectric sensors, or low-power microwave sensors. These sensors can efficiently detect the user's contact with the shaver and transmit signals to the main control board to start or stop the motor. For example, capacitive sensing electrodes can accurately sense changes in capacitance, making them suitable for hand grip sensing. Photoelectric sensors can detect changes in ambient light, making them suitable for detecting contact between the shaver foil and skin. Low-power microwave sensors can penetrate materials of a certain thickness, making them ideal for detecting the user's approach to the shaver. By combining different types of sensors, the shaver can respond more intelligently and sensitively to user movements and environmental changes.

[0054] As an optional implementation, the secondary sensing module is a capacitive sensing electrode or a water immersion sensor.

[0055] In practice, the secondary sensing module can be a capacitive sensing electrode or a water immersion sensor. When the shaver is immersed in water, the secondary sensing module generates a signal change by sensing the presence of water. After receiving the signal, the main control board can promptly control the motor to stop running.

[0056] Preferably, the secondary sensing module can be a water immersion sensor, which can respond quickly when the shaver is accidentally immersed in water. The combination of the water immersion sensor and the main control board gives the shaver a highly sensitive waterproof function; once water is detected, the system will immediately issue a stop signal to prevent the shaver motor from continuing to operate. This design makes the shaver safer and more reliable in high-humidity environments or environments with potential water intrusion risks.

[0057] Optionally, the technical solution of this application can also be applied to household devices such as sensor-activated hair trimmers, nose hair trimmers, and hair removal devices.

[0058] This application provides an induction shaver, including a secondary sensor module, a motor, and a main control board. The secondary sensor module is located inside the shaver body and connected to the main control board. The main control board is connected to the motor. When the induction shaver is in the activated state, the main control board controls the motor to shut off when it detects a signal change from the secondary sensor module. When the induction shaver is immersed in water, if it accidentally starts due to water contact, the water enters the shaver body through the blades, contacts the secondary sensor module, and generates a signal change. The main control board can then control the motor to stop, preventing the induction shaver from failing to stop automatically after accidental activation.
