[0014] The present invention also provides a method for using a household mirror cabinet with lights, which is applied to a household mirror cabinet with lights. The method for using a household mirror cabinet with lights comprises the following steps: Step S1: The device is provided with a sensing component to sense whether a person approaches the mirror cabinet body and wants to open the cabinet door. When sensing that someone wants to open the cabinet door, the sensing component triggers the positioning component to unlock the positioning component, thereby releasing the restraint on the cabinet door, allowing the person to directly open the cabinet door. At the same time, the lighting inside the storage slot is also turned on to facilitate people's use; Step S2: When the sensing component is operating, the human body emits infrared radiation of a specific wavelength. Therefore, when a person places their hand into the recess, the infrared radiation emitted by the human body is focused onto the pyroelectric infrared sensor through the Fresnel lens. When the pyroelectric infrared sensor receives the infrared radiation from the human body, the temperature of the pyroelectric element inside it changes, causing the charge density on its surface to change, generating a pyroelectric current. This current signal is very weak and needs to be processed by an amplifier. The amplified current triggers the switching device to operate, turning on the circuit of the first coil, thereby activating the positioning component. Step S3: When the switching device is operating, the current amplified by the amplifier flows into the second coil, causing the second iron core to generate magnetism, thereby attracting the iron rod downward. As the iron rod slides downward, it drives the metal bridge plate downward until the copper blocks at both ends of the metal bridge plate contact the second contacts. At this point, the first coil circuit is connected, allowing current to flow through the first coil, thereby triggering the positioning assembly to operate. Step S4: When the positioning component is working, when the first coil has current flowing through it, the first iron core will generate magnetism, thereby adsorbing the damping iron rod, causing the damping iron rod to slide toward the first iron core. During the sliding, one end of the positioning plate will slide out of the positioning slot, thereby releasing the positioning of the cabinet door.
[0015] Compared with the prior art, the present invention has the following beneficial effects: The device is provided with a sensing component to sense whether a person approaches the mirror cabinet body and wants to open the cabinet door. When it senses that someone wants to open the cabinet door, the sensing component will trigger the positioning component to unlock the positioning component, thereby releasing the restraint on the cabinet door, allowing people to directly open the cabinet door. At the same time, the lighting inside the storage slot will be illuminated, making it easier for people to use. 2. In the present invention, when the sensing component is working, if a person approaches the mirror cabinet body, the sensing component will not be triggered. However, when the person reaches into the recess to open the cabinet door, the sensing component will be triggered. When the person reaches into the recess, the pyroelectric infrared sensor will be activated under the detection of the Fresnel lens, thereby triggering the switching device to operate, making the circuit of the first coil conductive, and thus activating the positioning component. 3. In the present invention, when the positioning assembly is in operation, when current is conducted through the first coil, the first iron core generates magnetism, which in turn attracts the damping iron rod, causing the damping iron rod to slide toward the first iron core. During the sliding, one end of the positioning plate is driven to slide out of the positioning slot, thereby releasing the positioning of the cabinet door. 4. In the present invention, when the switching device is operating, current flowing into the second coil causes the second iron core to generate magnetism, thereby attracting the iron rod downward. When the iron rod slides downward, it drives the metal bridge plate downward until the copper blocks at both ends of the metal bridge plate contact each other with the second contact points. At this time, the first coil circuit can be turned on, allowing current to flow through the first coil. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The effect achieved is that the device can sense whether there is a person approaching the mirror cabinet body 1 and wanting to open the cabinet door 4 by setting a sensing component. When it senses that someone wants to open the cabinet door 4, the positioning component will be triggered by the sensing component to unlock the positioning component, thereby releasing the constraint on the cabinet door 4, allowing people to directly open the cabinet door 4. At the same time, the lighting lamp 10 inside the storage slot 3 will be lit, which is convenient for people to use. By setting a wedge-shaped slide 12, when the cabinet door 4 is closed, the wedge-shaped slide 12 will contact the inclined surface of one end of the positioning plate 13, thereby guiding one end of the positioning plate 13 into the positioning slot 11 to position the cabinet door 4.
[0021] like Figure 1 、 Figure 2 、 Figure 4 and Figure 7 As shown, the sensing component includes a Fresnel lens 29, a mounting groove 26 is provided inside the mirror cabinet body 1, and a conical opening 28 is provided on the inner bottom surface of the mounting groove 26. The bottom of the conical opening 28 passes through the inner top surface of the recess 6, and the Fresnel lens 29 is fixed between the inner walls of the conical opening 28 near the bottom edge. An inner top surface of the mounting groove 26 provides an inner cavity 27, and a pyroelectric infrared sensor 30 is provided between the inner walls of the mounting groove 26. Two pyroelectric elements 31 are provided inside the pyroelectric infrared sensor 30, and an amplifier 32 is provided inside the inner cavity 27. An insulating column 33 is provided in the middle of the inner cavity 27, and a switching device is provided inside the insulating column 33. The amplifier 32 is electrically connected to the pyroelectric infrared sensor 30.
[0022] The effect achieved is that, since the human body emits infrared rays of a specific wavelength, when people put their hands into the recess 6, the infrared rays emitted by the human body are focused onto the pyroelectric infrared sensor 30 through the Fresnel lens 29. When the pyroelectric infrared sensor 30 receives the infrared radiation from the human body, the temperature of the pyroelectric element 31 inside it changes, causing the charge density on its surface to change, generating a pyroelectric current. This current signal is very weak and needs to be processed by the amplifier 32. The amplified current triggers the switching device to work, so that the circuit of the first coil 17 is turned on, and then the positioning component works.
[0023] like Figure 4 、 Figure 5 and Figure 7As shown, the switching device includes an iron rod 38, a second reciprocating cavity 34 is opened inside the insulating column 33, a second driving groove 35 is opened inside the insulating column 33 below the second reciprocating cavity 34, a second iron core 36 is fixed to the inner bottom surface of the second driving groove 35, and a second coil 37 is wound around the outer surface of the second iron core 36. The iron rod 38 is located inside the second reciprocating cavity 34, and the bottom of the iron rod 38 slides through the inside of the second driving groove 35. A protective pad 46 is fixed to the bottom of the iron rod 38, and the protective pad 46 is located inside the second driving groove 35 and opposite to the second iron core 36. An insulating pad 39 is fixed to the top of the iron rod 38, and a metal bridge is fixed to the top of the insulating pad 39. Plate 40, copper blocks 41 are fixed at both ends of the metal bridge plate 40, a fixing ring 42 is fixed in the middle between the inner walls of the second reciprocating cavity 34, and second contacts 44 are fixed to the top of the fixing ring 42 near the edges on both sides, and first contacts 43 are fixed to the inner top surface of the second reciprocating cavity 34 near the edges on both sides. The top and bottom of the two copper blocks 41 are respectively attached to the bottom of the first contact 43 and the top of the second contact 44. A second spring 45 is fixed between the bottom of the insulating pad 39 and the inner bottom surface of the second reciprocating cavity 34. The two second contacts 44 are respectively electrically connected to the first coil 17, and the two ends of the amplifier 32 are respectively electrically connected to the second coil 37.
[0024] The effect achieved is that the current amplified by the amplifier 32 flows into the second coil 37, causing the second iron core 36 to generate magnetism, thereby attracting the iron rod 38 downward. When the iron rod 38 slides downward, it drives the metal bridge plate 40 to slide downward until the copper blocks 41 at both ends of the metal bridge plate 40 and the second contacts 44 are in contact with each other. At this time, the circuit of the first coil 17 can be turned on, allowing current to flow through the first coil 17, thereby triggering the positioning component to work.
[0025] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 and Figure 7As shown, the positioning assembly includes a positioning plate 13, one end of the positioning plate 13 is inclined near the front edge, a first reciprocating cavity 14 is opened inside the mirror cabinet body 1, a first driving groove 15 is opened inside the mirror cabinet body 1 on one side of the first reciprocating cavity 14, a first iron core 16 is fixed to the inner wall of one side of the first driving groove 15, a first coil 17 is wound around the outer surface of the first iron core 16, a protective plate 18 is fixed to one end of the first iron core 16, a damping iron rod 22 is provided inside the first reciprocating cavity 14, one end of the damping iron rod 22 slides through the inside of the first driving groove 15, a rubber pad 19 is fixed to one end of the damping iron rod 22, the rubber pad 19 is located inside the first driving groove 15 and opposite to the protective plate 18, a slide plate 25 is fixed to the other end of the damping iron rod 22, and the slide plate 25 It is slidably connected between the inner walls of the first reciprocating cavity 14, and a damping sleeve 20 is provided between the first reciprocating cavity 14 and the first driving groove 15. The damping iron rod 22 is slidably connected to the inner side of the damping sleeve 20, and the outer surface of the damping iron rod 22 is damping-fitted with the inner wall of the damping sleeve 20. The positioning plate 13 is fixed on one side of the slide plate 25, and one end of the positioning plate 13 passes through the interior of the storage slot 3 and extends to the interior of the positioning slot 11. A first spring 23 is fixed between the outer surface of one side of the slide plate 25 and the inner wall of one side of the first reciprocating cavity 14. Copper contacts 21 are fixed to the inner walls on both sides of the first reciprocating cavity 14, and copper sheets 24 are fixed to the outer surfaces on both sides of the slide plate 25. The two copper sheets 24 are respectively fitted with the copper contacts 21, and the two copper contacts 21 are respectively electrically connected with the lighting lamp 10.
[0026] The effect achieved is that when the first coil 17 has no current conducting, when the cabinet door 4 is closed, the inclined surface of the wedge-shaped slide 12 will first fit into the inclined surface of one side of the positioning plate 13, and then one end of the positioning plate 13 will slide into the interior of the positioning groove 11 under the guidance of the inclined surface. At the same time, under the elastic force of the first spring 23, one end of the positioning plate 13 can be driven to insert into the interior of the positioning groove 11, so that it can position the cabinet door 4. When the first coil 17 has current conducting, the first iron core 16 will generate magnetism, and then the damping iron rod 22 will be adsorbed, so that The damping iron rod 22 slides toward the first iron core 16, and when sliding, it will drive one end of the positioning plate 13 to slide out from the inside of the positioning groove 11, thereby releasing the positioning of the cabinet door 4. At the same time, when the damping iron rod 22 slides to the rubber pad 19 and the protective plate 18 are in contact with each other, the copper contact 21 and the copper sheet 24 are in contact with each other, so that the lighting lamp 10 is turned on and emits light. When sliding, the damping iron rod 22 and the inner wall of the damping sleeve 20 have a damping force due to the damping fit, so the damping iron rod 22 will not generate a large impact force when sliding to the end, and the first spring 23 is in a compressed state at this time.
[0027] For example, in one embodiment, the present invention further provides a method for using a household mirror cabinet with light, which is applied to the above household mirror cabinet with light, and includes the following steps: Step S1: The device is provided with a sensing component to sense whether a person approaches the mirror cabinet body 1 and wants to open the cabinet door 4. When sensing that someone wants to open the cabinet door 4, the sensing component triggers the positioning component to unlock the positioning component, thereby releasing the constraint on the cabinet door 4, allowing people to directly open the cabinet door 4. At the same time, the lighting lamp 10 inside the storage slot 3 is also illuminated to facilitate people's use; Step S2: When the sensing component is operating, the human body emits infrared radiation of a specific wavelength. Therefore, when a person inserts a hand into the recess 6, the infrared radiation emitted by the human body is focused by the Fresnel lens 29 onto the pyroelectric infrared sensor 30. When the pyroelectric infrared sensor 30 receives the infrared radiation from the human body, the temperature of the pyroelectric element 31 inside the pyroelectric infrared sensor 30 changes, causing the charge density on its surface to change, generating a pyroelectric current. This current signal is very weak and needs to be processed by the amplifier 32. The amplified current triggers the switching device to operate, making the circuit of the first coil 17 conductive, thereby activating the positioning component. Step S3: When the switching device is operating, the current amplified by the amplifier 32 flows into the second coil 37, causing the second iron core 36 to generate magnetism, thereby attracting the iron rod 38 downward. As the iron rod 38 slides downward, it drives the metal bridge plate 40 downward until the copper blocks 41 at both ends of the metal bridge plate 40 contact the second contacts 44. At this point, the first coil 17 is conductive, allowing current to flow through the first coil 17, thereby triggering the positioning assembly to operate. Step S4: When the positioning component is working, when the first coil 17 has current flowing through it, the first iron core 16 will generate magnetism, thereby adsorbing the damping iron rod 22, causing the damping iron rod 22 to slide toward the first iron core 16. When sliding, it will drive one end of the positioning plate 13 to slide out from the inside of the positioning groove 11, thereby releasing the positioning of the cabinet door 4.

10. A method for using a household mirror cabinet with light, which is applied to a household mirror cabinet with light as claimed in any one of claims 1 to 9, characterized in that: The following steps are involved: Step S1: The device can sense whether a person approaches the mirror cabinet body (1) and wants to open the cabinet door (4) by setting a sensing component. When sensing that someone wants to open the cabinet door (4), the sensing component triggers the positioning component to unlock the positioning component, thereby releasing the constraint on the cabinet door (4), allowing people to directly open the cabinet door (4). At the same time, the lighting lamp (10) inside the storage slot (3) is also lit, making it convenient for people to use; Step S2: When the sensing component is working, since the human body emits infrared rays of a specific wavelength, when a person puts his hand into the recess (6), the infrared rays emitted by the human body are focused onto the pyroelectric infrared sensor (30) through the Fresnel lens (29). When the pyroelectric infrared sensor (30) receives the infrared radiation from the human body, the temperature of the pyroelectric element (31) inside it changes, causing the charge density on its surface to change, generating a pyroelectric current. This current signal is very weak and needs to be processed by the amplifier (32). The amplified current triggers the switching device to work, so that the circuit of the first coil (17) is turned on, thereby making the positioning component work; Step S3: When the switching device is working, the current amplified by the amplifier (32) flows into the second coil (37), causing the second iron core (36) to generate magnetism, thereby attracting the iron rod (38) downward. When the iron rod (38) slides downward, it drives the metal bridge plate (40) to slide downward until the copper blocks (41) at both ends of the metal bridge plate (40) and the second contact (44) fit together. At this time, the circuit of the first coil (17) is turned on, causing current to flow through the first coil (17), thereby triggering the positioning component to work; Step S4: When the positioning assembly is working, when the first coil (17) is conducting current, the first iron core (16) generates magnetism, thereby adsorbing the damping iron rod (22), causing the damping iron rod (22) to slide toward the first iron core (16). During the sliding, one end of the positioning plate (13) is driven to slide out from the inside of the positioning groove (11), thereby releasing the positioning of the cabinet door (4).
