Description

Technical Field

[0001] This invention belongs to the field of optical eyewear technology, specifically relating to a low-electric-driven, single-unit, dual-control intelligent defogging nano-eyeglasses and its defogging control method. Background Technology

[0002] Fogging of eyeglass lenses is a common phenomenon in daily life. Especially in special scenarios such as transportation and low-temperature cold storage, severe fogging can directly cause blind spots, leading to safety accidents. Therefore, effectively solving the problem of lens fogging is of significant practical value and real importance for ensuring personal safety and maintaining the smooth operation of various tasks.

[0003] However, existing electrically heated defogging devices have significant limitations in their switch configurations: First, they lack intelligence. Most devices use a single physical mechanical button, which is not only easily damaged but also detracts from the overall aesthetics of the glasses, affecting the user experience. A few devices use a lens temperature-sensing control design; however, the temperature change at the moment the lens fogs up is extremely small, making it difficult for the temperature sensor to effectively capture, resulting in low detection accuracy and slow response. This type of design has fundamental flaws and is difficult to apply to industrialization. Second, there is a disconnect between manual touch control and automatic triggering. Currently, few designs simultaneously accommodate both user subjective control and system objective judgment. When the environment changes drastically or the user has specific defogging needs, the defogging device cannot promptly activate its efficient defogging function.

[0004] Meanwhile, traditional defogging methods often involve using defogging sprays for lenses, applying external heating films, or embedding heating wires within the eyeglass frames. However, defogging sprays have a short working time, are prone to uneven application, have limited applicability, and are cumbersome to use. Applying external heating films increases lens thickness, compromises the eyeglass design, affects the visual quality and aesthetics of the wearer, and is also prone to falling off, reducing lens lifespan. Embedding heating wires within the frame results in a heavy frame and an excessively long response time.

[0005] In conclusion, inventing a defogging glasses system that combines intelligent control with aesthetic design is imperative. The core challenges lie in: optimizing the switching components to break the deadlock of single-mode switching control and establish a combined subjective and objective control mechanism; and innovating the lens materials and conductive interfaces of the frame to avoid complex circuit wiring layouts and establish an electrical connection system that combines high stability with aesthetic appeal. Summary of the Invention

[0006] The purpose of this invention is to provide a low-voltage driven single-unit dual-control intelligent defogging nanoglasses to solve the problem that the existing electric heating defogging glasses have a single control mode, which cannot take into account both the automatic triggering of fogging caused by temperature difference and the manual intervention of fogging caused by non-temperature difference, resulting in insufficient scene adaptability.

[0007] To address the aforementioned problems, this invention proposes a low-electric-driven, single-unit, dual-control intelligent defogging nanoglasses. The technical solution adopted is as follows: A low-voltage driven single-unit dual-control intelligent defogging nano glasses includes a glasses frame, glasses support temples connected to both sides of the glasses frame, nano glasses lenses with full-area electrothermal conversion function embedded in the glasses frame, a power supply module and a control switch assembly, wherein the glasses frame is provided with metal contact points that make electrical contact with the nano glasses lenses; The control switch assembly includes a temperature-sensitive trigger switch and a fingerprint sensor switch respectively disposed on the left and right eyeglass support temples, which together form a dual-intelligent single-link dual-control mechanism; the power supply module, temperature-sensitive trigger switch, fingerprint sensor switch, metal contact point and nano-eyeglass lens are electrically connected through micro wires arranged in the eyeglass frame to form a weak current drive control circuit. The temperature-sensitive trigger switch is used to detect the ambient temperature and automatically control the on / off state of the weak current drive control circuit based on the change of ambient temperature, so as to realize automatic defogging control in the case of fogging induced by temperature difference; the fingerprint sensor switch is used to receive manual touch signal and control the on / off state of the weak current drive control circuit, so as to realize manual defogging control in various fogging scenarios. The low-voltage drive control circuit has a built-in timing unit, which is used to perform a secondary determination of the ambient temperature after manual control of defogging, in conjunction with the temperature-sensitive trigger switch, so as to realize the automatic continuation or shutdown of the defogging state.

[0008] Furthermore, the temperature-sensitive trigger switch incorporates a miniature temperature sensor and a control unit. The miniature temperature sensor is used to detect the ambient temperature in real time. When the ambient temperature difference reaches a preset threshold range within a preset time period, the control unit automatically closes the low-voltage drive control circuit, and the current is introduced into the nano-glasses lens through the metal contact point to achieve full-area heating and defogging. When the ambient temperature difference is detected to be within a preset threshold range, the control unit automatically disconnects the low-voltage drive control circuit to turn off the defogging function.

[0009] Furthermore, when defogging is manually activated via the fingerprint sensor switch, the timing unit simultaneously starts timing; after the timing period expires, if the temperature sensor trigger switch detects that the ambient temperature difference reaches the preset opening threshold range, the circuit is maintained to continue defogging; if the ambient temperature difference is detected to be within the preset closing threshold range, the circuit is automatically disconnected by the temperature sensor trigger switch or manually disconnected by the fingerprint sensor switch.

[0010] Furthermore, the control switch assembly integrates a Bluetooth communication unit, which supports custom adjustment of the operating parameters of the defogging system containing a miniature temperature sensor and a timing unit via a mobile device when there is no network connection; the operating parameters include a preset opening threshold range, a preset closing threshold range, and a timing cycle.

[0011] Furthermore, the nano-eyeglasses lens is made of nano-inorganic conductive particles uniformly composited with high-transmittance optical resin material. When the lens body is energized, it can generate heat autonomously, and uniform heat generation throughout the entire area achieves balanced defogging.

[0012] Furthermore, the metal contact points are made of a metal material that combines elasticity and high conductivity. When the glasses are assembled, the metal contact points and the nano-lens form a weldless physical compression electrical connection based on the compressive stress of the glasses frame on the nano-lens.

[0013] Furthermore, the power supply module includes a miniature lithium battery, which is embedded inside the right eyeglass support leg. The output voltage of the miniature lithium battery is 3.7V, and the peak current when the defogging system is started is controlled within 350mA. The temperature-sensitive trigger switch is rectangular and located on the outside of the left eyeglass support leg, and the fingerprint sensor switch is elliptical and located on the outside of the right eyeglass support leg.

[0014] Furthermore, the power supply module also includes a solar panel, which is disposed on the outside of the eyeglass frame and electrically connected to the micro lithium battery, for converting light energy into electrical energy to charge the micro lithium battery.

[0015] Furthermore, both the temperature-sensitive trigger switch and the fingerprint sensor switch independently control the on / off state of the low-voltage drive control circuit. Their control logics do not interfere with each other, together forming a dual-control system that complements automatic sensing and manual intervention.

[0016] This invention also proposes a defogging control method for a weakly electrically driven single-unit dual-control intelligent defogging nanoglasses. The technical solution adopted is as follows: A defogging control method for a low-electric-driven, single-unit, dual-control intelligent defogging nanoglasses includes an automatic defogging mode and a manual defogging mode. The automatic defogging mode includes the following steps: S11: Temperature-sensitive trigger switch collects ambient temperature in real time; S12: Determine whether the ambient temperature difference within a preset time period reaches a preset activation threshold range, wherein... If so, the weak current drive control loop is closed, and the nano-glasses lens is powered on and heated to perform full-area defogging; If not, then keep the weak current drive control circuit disconnected; S13: During the defogging process, the ambient temperature is continuously monitored. When the ambient temperature difference is within the preset shut-off threshold range, the weak current drive control circuit is disconnected and the defogging is terminated. The manual defogging mode includes the following steps: S21: After receiving a manual touch signal, the fingerprint sensor switch closes the low-voltage drive control circuit, starts the defogging function, and triggers the timing unit to start timing. S22: After the timing cycle expires, the temperature sensor trigger switch is invoked to perform a secondary ambient temperature detection; S23: If the ambient temperature difference is detected to be within the preset opening threshold range, it is determined that there is a risk of continuous fogging, and the weak current drive control circuit is kept connected to continuously defog; if the ambient temperature difference is detected to be within the preset closing threshold range, it is determined that the risk of fogging has been eliminated, and the weak current drive control circuit is disconnected to terminate defogging. Compared with the prior art, this application has the following beneficial effects: This invention employs a dual-intelligent single-unit dual-control mechanism, combining a temperature-sensitive trigger switch and a fingerprint sensor switch. This allows users to achieve rapid, efficient, and even defogging of lenses in various complex and foggy conditions, significantly improving scenario adaptability and ease of use. The temperature-sensitive trigger switch and fingerprint sensor switch enable dual control of the current circuit between the micro-lithium battery and the nano-lens. This can be automatically triggered by ambient temperature differences or manually activated via fingerprint recognition, driving the nanoparticles to generate heat rapidly and evenly within the lens, achieving precise control over the heating state of the nano-lens. Compared to traditional single-unit single-control technology with frame heating or external film application, the dual-intelligent single-unit dual-control switch design controls the heating program of the nano-lens, enabling flexible triggering of the intelligent defogging system in various environments. Simultaneously, the fingerprint sensor switch avoids the defects of traditional physical buttons, such as easy damage and accidental touches, thereby enhancing the device's operational reliability, anti-accidental touch performance, and long-term structural durability.

[0017] These nano-lenses heat up rapidly upon the application of an electric current, achieving highly efficient and instantaneous defogging. The integrated lens design, utilizing nanomaterials, avoids limitations imposed by lens geometry, significantly enhancing aesthetics and comfort, thus achieving an organic fusion of intelligence and aesthetic design. These nano-lenses eliminate the need for external heating wires or films, fundamentally avoiding the bulkiness and structural limitations of traditional technologies. While achieving lightweight eyewear, they also meet users' personalized needs, significantly improving wearing comfort and aesthetics.

[0018] This invention breaks the deadlock of single-switch control by optimizing the switching components, establishing a combined subjective and objective control mechanism; it innovates the conductive interface between lens materials and frames, avoiding complex circuit wiring layouts, and establishing an electrical bonding system that combines high stability and aesthetic appeal, precisely adapting to various fogging environments, achieving coordinated control of automatic triggering and manual sensing, and comprehensively optimizing the intelligent lens defogging control system; at the same time, it eliminates safety hazards from the electrical source by combining safe low-voltage and milliampere-level current precise control technology, ensuring absolute safety when worn close to the body.

[0019] The temperature-sensitive trigger switch incorporates a miniature temperature sensor and a control unit. The miniature temperature sensor detects the ambient temperature in real time. When the ambient temperature difference reaches a preset threshold range within a preset time period, the control unit automatically closes the low-voltage drive control circuit, and current is introduced through the metal contact point to the nano-glasses lens to achieve full-area heating and defogging. When the ambient temperature difference is detected to be within a preset shutdown threshold range, the control unit automatically disconnects the low-voltage drive control circuit to shut down the defogging function. This effectively avoids false triggering caused by small fluctuations in ambient temperature and improves the triggering accuracy of automatic defogging.

[0020] When defogging is manually activated via a fingerprint sensor switch, the timing unit simultaneously starts timing. After the timing period expires, if the temperature-sensitive trigger switch detects that the ambient temperature difference reaches a preset opening threshold, the circuit remains connected for continuous defogging. If the ambient temperature difference is detected to be within a preset closing threshold, the circuit is automatically disconnected by the temperature-sensitive trigger switch or manually disconnected by the fingerprint sensor switch. Users only need to activate the system with a single touch. After the timing period expires, the system automatically determines whether to continue defogging based on the ambient temperature, balancing immediate responsiveness in non-temperature difference scenarios with subsequent automation. Simultaneously, a dual-path shutdown mechanism with automatic and manual disconnection ensures that the system can automatically end defogging while retaining the user's right to manually intervene at any time, improving the reliability and fault tolerance of the control logic and adapting to diverse user operating habits.

[0022] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0023] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0024] Specific embodiment 1 of the present invention: Weak current driven single-unit dual-control intelligent defogging nanoglasses In this embodiment, as Figure 1 As shown, the low-voltage driven single-unit dual-control intelligent defogging nano glasses include a glasses frame 3, glasses support legs 8 connected to both sides of the glasses frame 3, nano glasses lens 6 with full-area electrothermal conversion function embedded in the glasses frame 3, power supply module and control switch assembly, and the nano glasses lens 6 is the core carrier of the defogging function.

[0025] The eyeglass frame 3 has multiple metal contact points 5 that make electrical contact with the nano-lens 6. The control switch assembly includes a temperature-sensitive trigger switch 7 and a fingerprint sensor switch 2, which are respectively located on the left and right eyeglass support legs 8, forming a dual-intelligent single-link dual-control mechanism. The power supply module, temperature-sensitive trigger switch 7, fingerprint sensor switch 2, metal contact points 5, and nano-lens 6 are electrically connected through micro-wires arranged in the eyeglass frame 3 to form a low-voltage drive control circuit. The temperature-sensitive trigger switch 7 is used to detect the ambient temperature and automatically control the on / off state of the low-voltage drive control circuit based on changes in ambient temperature, realizing automatic defogging control in temperature-induced fogging scenarios. The fingerprint sensor switch 2 is used to receive manual touch signals and control the on / off state of the low-voltage drive control circuit, realizing manual defogging control in various fogging scenarios, forming a control circuit. The low-voltage drive control circuit has a built-in timing unit, which is used to perform a secondary determination of ambient temperature after manual defogging control in conjunction with the temperature-sensitive trigger switch 7, realizing the automatic continuation or shutdown of the defogging state.

[0026] In this embodiment, the temperature-triggered switch 7 incorporates a miniature temperature sensor and a control unit. The miniature temperature sensor detects the ambient temperature in real time. When the ambient temperature difference reaches a preset opening threshold range within a preset time period, the control unit automatically closes the low-voltage drive control circuit, and current is introduced into the nano-eyeglass lens 6 through the metal contact point 5 to achieve full-area heating and defogging. When the ambient temperature difference is detected to be within a preset closing threshold range, the control unit automatically disconnects the low-voltage drive control circuit to turn off the defogging function. Here, the preset time period is 3 seconds, and the preset opening threshold range is... -3℃ or 3℃; the preset shut-off threshold range is -0.5~0.5℃.

[0027] When defogging is manually activated via fingerprint sensor switch 2, the timing unit starts timing simultaneously. After the timing period expires, if the temperature sensor trigger switch 7 detects that the ambient temperature difference reaches the preset opening threshold range, the circuit remains connected for continuous defogging. If the ambient temperature difference is within the preset closing threshold range, the circuit is automatically disconnected by the temperature sensor trigger switch 7 or manually disconnected by the fingerprint sensor switch 2. Here, the timing period is 5 minutes.

[0028] Among them, the temperature-sensitive trigger switch 7 and the fingerprint sensor switch 2 independently control the on / off state of the low-voltage drive control circuit. Their control logics do not interfere with each other, and together they form a dual control system that complements automatic sensing and manual intervention.

[0029] Since lens fogging is not solely caused by ambient temperature differences—for example, when wearing a mask, the exhaled warm, moist air blows directly onto the lens surface, causing fogging—the ambient temperature difference may not yet reach the set threshold of the temperature-sensitive trigger switch 7, leading to defogging failure. For such sudden fogging scenarios not caused by temperature differences, users can use the fingerprint sensor switch 2 to turn the heating circuit consisting of the micro lithium battery 1, metal contact points 5, and nano-lens 6 on and off at any time to promptly clear the fog from the lenses.

[0030] Specific embodiment 2 of the present invention: Weak current driven single-unit dual-control intelligent defogging nanoglasses Based on the above-described technical concept of the present invention, or based on the specific embodiments of the present invention described above, another embodiment is provided below.

[0031] In this embodiment, as Figure 1 and Figure 2As shown, the control switch assembly integrates a Bluetooth communication unit, supporting connection with a mobile device even without a network. The mobile device allows for customized adjustment of the operating parameters of the defogging system, which includes a miniature temperature sensor and a timing unit. These operating parameters include preset on / off threshold ranges, preset off threshold ranges, and timing cycles. Here, the Bluetooth communication unit is a Bluetooth communication chip. The Bluetooth communication unit enables hardware and software interaction. Based on different geographical environments and individual user preferences, users can flexibly set and adjust parameters such as the timing cycle and temperature thresholds via a mobile app without requiring a network connection. This comprehensively adapts to various complex fogging conditions, significantly enhancing the product's flexibility and greatly improving the user experience.

[0032] Specific embodiment 3 of the present invention: Weak current driven single-unit dual-control intelligent defogging nanoglasses Based on the above-described technical concept of the present invention, or based on the specific embodiments of the present invention described above, another embodiment is provided below.

[0033] In this embodiment, as Figure 1 and Figure 2 As shown, the power supply module adopts a photovoltaic-driven safety low-voltage system. The power supply module includes a miniature lithium battery 1, which is embedded inside the right eyeglass support leg 8. The output voltage of the miniature lithium battery 1 is a safe standard voltage of 3.7V, and the peak current during defogging system startup is controlled within 350mA. A rectangular temperature-sensitive trigger switch 7 is located on the outside of the left eyeglass support leg 8, serving as a circuit control switch. An elliptical fingerprint sensor switch 2 is located on the outside of the right eyeglass support leg 8, also used to control the circuit's on / off state. The eyeglass support leg 8 provides a mounting platform for the miniature lithium battery 1 and the two control switches. The power supply module also includes a solar panel 4, arranged in a grid pattern, located on the outside of the eyeglass frame 3 and electrically connected to the miniature lithium battery 1. This solar panel converts solar energy into electrical energy to charge the miniature lithium battery 1, forming a charging circuit and achieving energy self-sufficiency. The solar panel 4 and the miniature lithium battery 1 are connected to construct a continuous low-voltage power source. Through the synergistic effect of a low-voltage environment and dynamic micro-current, both defogging efficiency and safety during wear are ensured.

[0034] In terms of circuit connection, the solar panel 4 is electrically connected to the micro lithium battery 1 to realize the charging function; the temperature-sensitive trigger switch 7, the fingerprint sensor switch 2, the metal contact point 5, the solar panel 4, the micro lithium battery 1, and the nano-eyeglass lens 6 are connected by micro wires in the eyeglass frame 3 to form a weak current drive control circuit.

[0035] Specific embodiment 4 of the present invention: Weak current driven single-unit dual-control intelligent defogging nanoglasses Based on the above-described technical concept of the present invention, or based on the specific embodiments of the present invention described above, another embodiment is provided below.

[0036] In this embodiment, as Figure 1 and Figure 2 As shown, the nano-lens 6 is made of nano-inorganic conductive particles uniformly composited with high-transparency optical resin material. When the lens body is energized, it generates heat autonomously, forming a load circuit. Uniform heat generation throughout the entire surface achieves balanced defogging, eliminating fogging caused by factors such as temperature differences, thus achieving highly efficient defogging. This invention avoids the bulkiness and structural limitations of traditional technologies that rely on external heating wires or heating films. Users can flexibly customize nano-lens 6 with various shapes according to their personalized aesthetics and wearing needs, thus expanding the freedom of product design.

[0037] Among them, the nano-glasses lens 6 integrates nano-scale heating materials directly into the lens substrate during the manufacturing process, ensuring that while the lens has a global conductive heating function, there is no gap between the heating element and the substrate, and no risk of delamination. Relying on the global conductive function of the nano-glasses lens 6, the lens can generate a uniform heat field distribution after being energized, effectively avoiding local overheating, thereby achieving all-round and efficient defogging.

[0038] The metal contact point 5 is made of a metal material that combines elasticity and high conductivity. When the glasses are assembled, the metal contact point 5 and the nano-lens 6 are physically bonded and electrically connected without soldering due to the compressive stress exerted by the frame 3 on the nano-lens 6. This connection method ensures that the contact surface maintains a constant contact pressure under the inertial impact of frequent removal and wearing of glasses or strenuous exercise, thus guaranteeing the mechanical strength of the connection and the performance stability during long-term use. The metal contact point 5 serves as the sole electrical interface between the control circuit and the actuator, connected to the micro-lithium battery 1 via a micro-wire, effectively concealing the complex wiring layout and maintaining the overall aesthetic appeal of the glasses.

[0039] In response to fogging of eyeglasses caused by ambient temperature differences, in addition to manually turning the defogging system on and off at any time via the fingerprint sensor switch 2, when the temperature sensor trigger switch 7 detects a drastic fluctuation in ambient temperature within a preset time (3 seconds) and the temperature difference change is within a preset activation threshold range (…), -3℃ or When the ambient temperature is below 3℃, the internal control unit of the temperature-sensitive trigger switch 7 closes, automatically connecting the heating circuit consisting of the micro lithium battery 1, metal contact point 5, and nano-lens 6. Current flows through the metal contact point 5 to the nano-lens 6, converting it into heat energy, generating heat, and raising the temperature to achieve full-area heating and defogging of the lens. When the temperature-sensitive trigger switch 7 detects that the ambient temperature difference is stabilizing and its fluctuation value is within the preset shutdown threshold range (-0.5~0.5℃), the circuit automatically cuts off, shutting off the defogging function without manual intervention.

[0040] For sudden fogging of eyeglasses caused by factors other than temperature differences (such as high humidity or human sweat), the user can touch the fingerprint sensor switch 2 located on the outside of the right eyeglass support leg 8. The system immediately activates the heating circuit consisting of the micro lithium battery 1, fingerprint sensor switch 2, metal contact point 5, and nano-eyeglass lens 6 by recognizing a preset biometric signal. This circuit integrates a timing unit, which starts timing simultaneously when the defogging system is activated (for 5 minutes). After the timing period expires, the system enters a secondary judgment logic based on environmental parameters. If the micro temperature sensor in the temperature-sensitive trigger switch 7 detects that the ambient temperature difference is still within the preset activation threshold range (…), the system will proceed accordingly. -3℃ or If the temperature is below 3℃, the risk of fogging is determined to still exist, and the system maintains the current loop connection to ensure continuous defogging. If the micro temperature sensor detects that the current ambient temperature fluctuation is within the preset shutdown threshold range (-0.5~0.5℃), it indicates that there is no risk of fogging on the lens. At this time, a dual shutdown path is provided: on the one hand, the temperature-triggered switch 7 releases an automatic shutdown command, automatically cutting off the current loop between the micro lithium battery 1 and the nano-eyeglass lens 6; on the other hand, the fingerprint sensor switch 2 also maintains manual intervention permission. This path, together with the temperature-triggered loop, constructs a single-link dual-control mechanism with coupled subjective and objective logic to ensure that the defogging system can efficiently defog under any extreme or complex working conditions, compensating for the lag of single automatic sensing in specific scenarios.

[0041] Specific embodiment 1 of the defogging control method for the weak current driven single-unit dual-control intelligent defogging nanoglasses of the present invention: A defogging control method for low-voltage driven single-unit dual-control intelligent defogging nanoglasses, including automatic defogging mode and manual defogging mode. The automatic defogging mode includes the following steps: S11: Temperature-sensitive trigger switch 7 collects ambient temperature in real time; S12: Determine whether the ambient temperature difference within a preset time period reaches a preset activation threshold range, wherein... If so, the weak current drive control loop is closed, and the nano-glasses lens 6 is powered on to heat up and perform full-area defogging; If not, then keep the weak current drive control circuit disconnected; S13: During the defogging process, the ambient temperature is continuously monitored. When the ambient temperature difference is within the preset shut-off threshold range, the weak current drive control circuit is disconnected and the defogging is terminated. The manual defogging mode includes the following steps: S21: After receiving a manual touch signal, the fingerprint sensor switch 2 closes the weak current drive control circuit, starts the defogging, and triggers the timing unit to start timing. S22: After the timing cycle expires, the temperature sensor trigger switch 7 is activated to perform a secondary ambient temperature detection; S23: If the ambient temperature difference is detected to be within the preset opening threshold range, it is determined that there is a risk of continuous fogging, and the weak current drive control circuit is kept connected to continuously defog; if the ambient temperature difference is detected to be within the preset closing threshold range, it is determined that the risk of fogging is eliminated, and the weak current drive control circuit is disconnected to terminate defogging.

10. A defogging control method for a weakly electrically driven single-unit dual-control intelligent defogging nanoglasses as described in any one of claims 1-9, characterized in that, Includes automatic and manual defogging modes. The automatic defogging mode includes the following steps: S11: Temperature-sensitive trigger switch (7) collects ambient temperature in real time; S12: Determine whether the ambient temperature difference within a preset time period reaches a preset activation threshold range, wherein... If so, the weak current drive control loop is closed, and the nano-glasses lens (6) is powered on and heated to perform full-area defogging; If not, then keep the low-voltage drive control circuit disconnected; S13: During the defogging process, the ambient temperature is continuously monitored. When the ambient temperature difference is within the preset shut-off threshold range, the weak current drive control circuit is disconnected and the defogging is terminated. The manual defogging mode includes the following steps: S21: After receiving the manual touch signal, the fingerprint sensor switch (2) closes the weak current drive control circuit, starts the defogging, and triggers the timing unit to start timing at the same time; S22: After the timing period expires, the temperature sensor trigger switch (7) is called to perform a secondary detection of the ambient temperature; S23: If the ambient temperature difference is detected to be within the preset opening threshold range, it is determined that there is a risk of continuous fogging, and the weak current drive control circuit is kept connected to continuously defog; if the ambient temperature difference is detected to be within the preset closing threshold range, it is determined that the risk of fogging is eliminated, and the weak current drive control circuit is disconnected to terminate defogging.
