All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without making creative efforts shall fall within the protection scope of the present application.

[0037] It should be noted that when a component is referred to as being "connected" to another component, it can be directly connected to the other component or there can also be an intermediate component. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this application belongs. The terms used in the description of this application herein are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0038] As Figure 1-10 shown, an ultraviolet germicidal lamp includes a panel housing 101, a back panel housing 106, at least one light-shielding door panel 102, a transmission mechanism 121, and at least one connecting rod mechanism 122, wherein:

[0039] The back panel housing 106 is buckled with the panel housing 101 and is located at the rear side of the panel housing, and a first chamber is formed between the two. The main controller 115, the human body sensing module 118, and the ultraviolet sensor module 119 are disposed in the first chamber;

[0040] The light shielding door panel 102 is hinged to the front side of the panel housing 101 and forms a second chamber with the panel housing 101 when closed. The second chamber is provided with a light source fixing bracket 110, and an ultraviolet light source 112 is installed on the light source fixing bracket 110;

[0041] The human body sensing module 118, the ultraviolet sensor module 119, the ultraviolet light source 112 and the transmission mechanism 121 are all electrically connected to the main controller 115;

[0042] The transmission mechanism 121 is fixed on the panel housing 101 or the back panel housing 106. The main controller 115 controls the transmission mechanism 121 to drive the light source fixing bracket 110 to move, thereby driving the ultraviolet light source 112 to move forward and backward;

[0043] The connecting rod mechanism 122 includes a connecting rod 122b, one end of which is slidably connected to the light source fixing bracket 110, and the other end is hinged to a shading door plate 102. When the light source fixing bracket 110 moves forward and backward, it drives the shading door plate 102 to open and close in linkage.

[0044] Among them, the back panel housing 106 and the panel housing 101 are buckled together to form a first chamber, and the buckling connection method can be a snap connection or a screw connection. The human body sensing module 118, the ultraviolet sensor module 119 and the main controller 115 of the first chamber are all fixed on the rear side of the panel housing 101, and can also be fixed on the back panel housing 106 or any other position of the ultraviolet germicidal lamp. The connection method can be screw fixation or snap connection. The light source fixing bracket 110 is a "匚" type structure, and the ultraviolet light source 112 includes a lamp holder. The ultraviolet light source 112 is connected and fixed to the light source fixing bracket 110 through the lamp holder and is vertically arranged in the recess of the light source fixing bracket 110, which is conducive to improving space utilization, achieving small and lightweight, and there is no obstruction on the left and right sides, and the light radiation range is wide. The ultraviolet light source 112 can be quickly disassembled and installed, which is convenient for maintenance and replacement. At least one light source fixing clamp ring 116 is also installed on the light source fixing bracket 110, and the light source fixing clamp ring 116 clamps the lamp tube of the ultraviolet light source 112 for support, which helps to improve the stability of the ultraviolet light source 112. It should be noted that the light source fixing bracket 110 can also be any structure, the light shielding door plate 102 and the connecting rod mechanism 122 can be any number, and one light shielding door plate 102 is connected to at least one connecting rod mechanism 122.

[0045] The transmission mechanism 121 is fixed on the panel housing 101 and connected to the light source fixing bracket 110, and is used to drive the light source fixing bracket 110 to drive the ultraviolet light source 112 to move back and forth. The transmission mechanism 121 can be a linear motion mechanism in the prior art, such as a gear-rack mechanism, a lead screw-nut mechanism, etc. At the same time, one end of the connecting rod 122b of the connecting rod mechanism 122 is slidably connected to the light source fixing bracket 110, and the other end is hinged to one of the light-shielding door panels 102. When the main controller 115 controls the transmission mechanism 121 to drive the light source fixing bracket 110 to move back and forth, the light-shielding door panel 102 is driven to move synchronously to realize opening and closing. Further, in the working state, the forward movement of the light source fixing bracket 110 drives the light-shielding door panel 102 to open. At this time, the light source fixing bracket 110 synchronously drives the ultraviolet light source 112 to be pushed out of the panel housing 101 of the ultraviolet germicidal lamp, so that the light coverage area of the ultraviolet light source 112 is larger, which is beneficial to expanding the disinfection and killing range. In the non-working state, the light source fixing bracket 110 drives the ultraviolet light source 112 to move backward and retract into the panel housing 101 of the ultraviolet germicidal lamp. At this time, the light source fixing bracket 110 synchronously drives the light-shielding door panel 102 to close, so that the light source fixing bracket 110 and the ultraviolet light source 112 are hidden in the second chamber, playing a role in hiding and protecting the ultraviolet light source 112, and making the structure more compact and the appearance simple and generous.

[0046] The human body induction module 118, the ultraviolet sensor module 119, the ultraviolet light source 112 and the transmission mechanism 121 are all electrically connected to the main controller 115. Among them, when the ultraviolet light source 112 is working, the ultraviolet sensor module 119 transmits the ultraviolet radiation intensity data to the main controller 115 in real time. At the same time, the human body induction module 118 also transmits the detected human body data to the main controller 115 in real time. The main controller 115 determines the light attenuation situation of the ultraviolet light source 112 according to the received ultraviolet radiation intensity data, so as to adjust the disinfection time, ensure the effectiveness and reliability of each disinfection, and detect abnormal opening through the ultraviolet sensor module 119 to ensure the safety and controllability of disinfection. At the same time, the main controller 115 also controls the ultraviolet light source 112 according to the data detected by the human body induction module 118 to ensure that the lamp is off when there is a person, improving the safety performance of the disinfection process.

[0047] Specifically, the backplane housing 106 is also provided with an outlet hole 107 for the power supply cable to pass through and a mounting hole for the snap - fixing of the rocker switch 108. The rocker switch 108 is electrically connected to the main controller 115 and is used to control the power switch. The outlet hole 107 and the rocker switch 108 can also be arranged at any position of the ultraviolet germicidal lamp. A mounting bracket 109 is also connected to the rear side of the backplane housing 106. The mounting bracket 109 can be directly fixed or fixed to the wall or cabinet through an intermediate member for hanging the ultraviolet germicidal lamp, which is beneficial to reducing the floor area and obstacle blockage and expanding the ultraviolet coverage rate. Moreover, the mounting bracket 109 can also be installed at the bottom of the ultraviolet germicidal lamp, adopting a floor - type support structure to meet different requirements.

[0048] In one embodiment, the transmission mechanism 121 includes a motor 121a, a rack - and - pinion mechanism 121b, a first connecting plate 121d, a second connecting plate 121e, and a third connecting plate 121h. Both the first connecting plate 121d and the third connecting plate 121h are fixedly connected to the panel housing 101. The motor 121a is fixedly connected to the third connecting plate 121h. The rack and pinion of the rack - and - pinion mechanism 121b are respectively fixedly connected to the second connecting plate 121e and the motor 121a. The second connecting plate 121e is fixedly connected to the light source fixing bracket 110. The motor 121a is electrically connected to the main controller 115. The main controller 115 controls the motor 121a to drive the rack - and - pinion mechanism 121b to move, thereby driving the light source fixing bracket 110 to drive the ultraviolet light source 112 to move back and forth.

[0049] Among them, as Figure 5 , 7 shown, to ensure the motion accuracy, the transmission mechanism 121 adopts a rack - and - pinion mechanism. The main controller 115 controls the motor 121a to drive the rack - and - pinion mechanism 121b to move, thereby driving the light source fixing bracket 110 to drive the ultraviolet light source 112 to move back and forth. It should be noted that the rotation angle of the light - shielding door panel 102 can also be changed by adjusting the stroke to change the radiation angle range of the ultraviolet light, and the rack - and - pinion mechanism can also be replaced by a lead - screw nut mechanism, etc.

[0050] In one embodiment, the transmission mechanism 121 further includes a first guiding mechanism 113 and a second guiding mechanism 121c. The first guiding mechanism 113 is a guide - rail slider mechanism, and the guide rail and the slider of the first guiding mechanism 113 are respectively fixedly connected to the panel housing 101 and the light source fixing bracket 110. The second guiding mechanism 121c is fixedly connected to the first connecting plate 121d and is slidably connected to the second connecting plate 121e.

[0051] Among them, to ensure the structural stability and the reliability of the movement of the transmission mechanism 121, the light source fixing bracket 110 is also connected with a guiding mechanism. Specifically, as Figure 4As shown in the figure, a first guiding mechanism 113 is connected to the upper side of the light source fixing bracket 110, and a second guiding mechanism 121c is provided on the lower side. The guide rail and the slider of the first guiding mechanism 113 are fixedly connected to the panel housing 101 and the light source fixing bracket 110 respectively. The second guiding mechanism 121c includes two guiding blocks that are fixedly connected to the first connecting plate 121d and symmetrically distributed. A guiding groove is formed in the guiding block, and the second connecting plate 121e is clamped in the two guiding grooves and slides back and forth along them. It should be noted that the number of guiding mechanisms can be arbitrary. For example, the light source fixing bracket 110 can also be provided with only one guiding mechanism at the bottom.

[0052] In one embodiment, the transmission mechanism 121 further includes a detection switch 121g and a plurality of detection switch induction plates 121f arranged side by side in the front and rear. The detection switch 121g is electrically connected to the main controller 115 and is fixed on the third connecting plate 121h. The detection switch induction plate 121f is fixedly connected to the second connecting plate 121e.

[0053] Among them, the detection switch 121g and two detection switch induction plates 121f arranged side by side in the front and rear are used in cooperation for limiting. When the detection switch 121g senses the detection switch induction plate 121f during the forward and backward movement, a signal is fed back to the main controller 115, and the main controller 115 controls the start and stop of the motor 121a. The detection switch induction plate 121f and the second connecting plate 121e are of a split or integral structure. If it is an integral structure, it is formed by sheet metal bending, which is easy to process and reduces production costs.

[0054] In one embodiment, the link mechanism 122 further includes a first rotating shaft 110a and a connecting seat 122a. The first rotating shaft 110a is fixedly connected to the light source fixing bracket 110, and the connecting seat 122a is fixedly connected to one of the light-shielding door panels 102. One end of the link 122b is slidably connected to the first rotating shaft 110a, and the other end is hinged to the connecting seat 122a.

[0055] Among them, the connecting rod mechanism 122 includes a connecting rod 122b, a first rotating shaft 110a and a connecting seat 122a, the first rotating shaft 110a is fixedly connected to the top or bottom of the light source fixing bracket 110, the connecting seat 122a is fixedly connected to one of the shading door panels 102, the connecting seat 122a can be an integrated or split structure with the corresponding shading door panel 102, and the shading door panel 102 is hinged to the panel housing 101, one end of the connecting rod 122b is provided with a waist-shaped groove, and the other end is provided with a round hole, a rotating shaft is provided on the connecting seat 122a, the first rotating shaft 110a is slidably connected to the waist-shaped groove on the connecting rod 122b, the rotating shaft on the connecting seat 122a is correspondingly hinged to the round hole on the connecting rod 122b, and when the light source fixing bracket 110 moves forward and backward, it drives the shading door panel 102 to move in conjunction, and the opening and closing is achieved by rotating left and right around the rotating pair formed at the hinge with the panel housing 101. The connecting rod mechanism 122 can also be connected to any position of the light source fixing bracket 110 and the light shielding door plate 102 .

[0056] In one embodiment, the ultraviolet germicidal lamp includes two symmetrically distributed light-shielding door panels 102 and four connecting rod mechanisms 122 , and each light-shielding door panel 102 is correspondingly connected to two connecting rod mechanisms 122 .

[0057] Among them, the present application preferably has two light-shielding door panels 102, each light-shielding door panel 102 has two connecting rod mechanisms 122 arranged side by side up and down, and the ultraviolet sterilization lamp is symmetrical in structure as a whole, and the structure is stable. Specifically, the upper and lower sides of the light-shielding door panel 102 are respectively connected to a rotating shaft, and each rotating shaft is hinged to the panel housing 101, so that the light-shielding door panel 102 can be rotated left and right around the rotating shaft to open and close when subjected to force. It should be noted that there can also be one light-shielding door panel 102, and each light-shielding door panel 102 is connected to at least one connecting rod mechanism 122, and the position and number of the connecting rod mechanism 122 can be arranged according to actual needs.

[0058] In one embodiment, the first chamber further has a built-in ballast 114 , the main controller 115 , the ballast 114 and the ultraviolet light source 112 are electrically connected in sequence, and the main controller 115 is also provided with a wireless communication module.

[0059] The ballast 114 is fixed to the rear side of the panel housing 101, and the connection method can be screw fixing or clamping. The main controller 115 controls the ballast 114 to provide stable power supply to the ultraviolet light source 112, so as to start or shut down the ultraviolet light source 112.

[0060] The main controller 115 can also be connected to the terminal device through a wireless communication module, such as through wireless communication methods like Zigbee, Bluetooth, WIFI, etc., or remotely controlled after connecting to the network through a gateway or router. The terminal device can be a mobile phone, computer, handheld remote control, etc. Relevant control, setting, disinfection record query, etc. operations can be performed through the terminal device, and group linkage control can be carried out by wirelessly connecting multiple ultraviolet germicidal lamps, which is convenient for human-computer interaction and more intelligent.

[0061] In one embodiment, a speaker module 117 and an indicator light module 120 are also built into the first chamber, and corresponding speaker holes 105 and status indicator light holes 103 are provided on the panel housing 101.

[0062] Among them, the speaker module 117 and the indicator light module 120 are fixed on the panel housing 101, and corresponding speaker holes 105 and status indicator light holes 103 are provided on the panel housing 101. Different voice contents are broadcast through the speaker module 117, and the on / off and flashing of different light sources of the indicator light module 120 are used to prompt the status information of the ultraviolet germicidal lamp. For example Figure 1 As shown, from left to right, the indicator light module 120 includes an ultraviolet germicidal lamp and terminal device connection status indicator light, a device failure indicator light, and a lamp life reminder indicator light. Specifically, the device online status indicator light: when it is off, it means that the ultraviolet germicidal lamp is not connected to the terminal device; when it is flashing, it means that the ultraviolet germicidal lamp is connecting to the terminal device; when it is constantly on, it means that the ultraviolet germicidal lamp is connected to the terminal device. The device failure indicator light: when it is off, it means that the device is working normally; when it is constantly on, it means that the device has a fault. The lamp life indicator light: when it is off, it means that the lamp is used normally and does not need to be replaced; when it is constantly on, it means to prompt to replace the lamp.

[0063] In one embodiment, a reflector 111 for reflecting the light of the ultraviolet light source 112 is also installed on the light source fixing bracket 110.

[0064] Among them, the reflector 111 is fixed to the light source fixing bracket 110, and can be fixed by screw connection or pasting, and is located at the rear side of the ultraviolet light source 112. When the ultraviolet light source 112 works, it can reflect ultraviolet light to effectively increase the radiation intensity and improve the sterilization effect.

[0065] In one embodiment, the human body sensing module 118 includes an infrared sensing sensor and a radar sensing sensor.

[0066] Among them, the human body induction module 118 is fixed on the panel housing 101 and includes an infrared induction sensor and a radar induction sensor. The cooperation of the two helps to expand the human body induction range. For example, the induction angle (i.e., range) of the conventional infrared induction function is limited to 140 degrees, and the triggering condition is a person, while the radar induction angle can reach 360 degrees. The cooperation of the two can expand the induction range. An infrared induction sensor transmission hole is also correspondingly opened on the panel housing 101, and an infrared sensor lens 104 is installed on the transmission hole to protect the infrared induction sensor. The human body induction module 118 can also be a single infrared induction sensor or a radar induction sensor.

[0067] The working principle of the ultraviolet germicidal lamp of this application:

[0068] When starting the working state, the main controller 115 controls the motor 121a of the transmission mechanism 121 to rotate forward (or reverse), driving the light source fixing bracket 110 to move forward, pushing the light-shielding door panel 102 to open. At this time, the light source fixing bracket 110 synchronously drives the ultraviolet light source 112 to be pushed out of the panel housing 101 of the ultraviolet germicidal lamp. When the detection switch 121g detects a signal, it sends it to the main controller 115. The main controller 115 controls the motor 121a of the transmission mechanism 121 to stop rotating. If the detection of the detection switch 121g times out, it is judged that there is a fault in the transmission process, and the corresponding voice prompt information is broadcast through the speaker module 117 and the device fault indicator light is lit through the indicator module 120 for prompt. After the ultraviolet light source 112 is pushed in place, that is, after the detection switch 121g detects a signal, the main controller 115 controls the ultraviolet light source 112 to turn on for disinfection work, and broadcasts the corresponding voice prompt information through the speaker module 117. At the same time, the main controller 115 detects the ultraviolet radiation intensity data after the ultraviolet light source 112 is turned on through the ultraviolet sensor module 119, determines the light attenuation situation of the ultraviolet light source 112, thereby adjusts the disinfection time, and detects abnormal opening situations to ensure the effectiveness and reliability of each disinfection. For example, when the detection data of the ultraviolet sensor module 119 is lower than the set value, the corresponding voice prompt information is broadcast through the speaker module 117 and the lamp life reminder indicator light is lit through the indicator module 120 for prompt; if it is abnormally turned on outside the opening time, the ultraviolet light source 112 detects the corresponding data through the ultraviolet sensor module 119, and the corresponding voice prompt information is broadcast through the speaker module 117 and the device fault indicator light is lit through the indicator module 120 for prompt. In the working state, pushing out the ultraviolet light source 112 helps to increase the light coverage area, thereby expanding the disinfection range and improving the disinfection efficiency, and detecting through the ultraviolet sensor module 119 to improve the disinfection effect and monitor abnormal opening situations.

[0069] Meanwhile, the ultraviolet light source 112 is controlled according to the human body data detected by the human body sensing module 118 to ensure that the light is off when people are present, improving the safety performance of the disinfection process. When the human body sensing module 118 senses the human body data, the main controller 115 immediately turns off the ballast 114, thereby turning off the ultraviolet light source 112 to end the disinfection work, and broadcasts corresponding voice prompt information through the speaker module 117. The main controller 115 controls the motor 121a of the transmission mechanism 121 to reverse (or forward), and the light source fixing bracket 110 drives the ultraviolet light source 112 to move backward and retract into the panel housing 101 of the ultraviolet germicidal lamp. At this time, the light source fixing bracket 110 synchronously drives the light-shielding door panel 102 to close. When the detection switch 121g detects a signal, it sends it to the main controller 115, and the main controller 115 controls the motor 121a of the transmission mechanism 121 to stop rotating, so that the light source fixing bracket 110 and the ultraviolet light source 112 are hidden in the second chamber, playing a role in hiding and protecting the ultraviolet light source 112. If the detection of the detection switch 121g times out, it is determined that there is a fault in the transmission process, and corresponding voice prompt information is broadcast through the speaker module 117 and the device fault indicator light is lit through the indicator module 120 for prompt. When the disinfection is completed and the work ends, the main controller 115 immediately turns off the ultraviolet light source 112, and the ultraviolet light source 112 is hidden in the second chamber. The specific process is the same as above and will not be repeated. In practical applications, the device can operate independently, or the main controller 115 is connected to the terminal device through the wireless communication module, and the terminal device realizes remote control and related device setting operations, etc. When connected to the terminal device, corresponding voice prompt information is broadcast through the speaker module 117 and the device online status indicator light is lit through the indicator module 120 for prompt. In the working state, it can be prompted by the cooperation of the indicator light and the voice, used to quickly know the device status, and can perform troubleshooting in time, etc., which is convenient to use.
