Description

Technical Field

[0001] The present invention relates to the technical field of energy-saving lamps, and particularly relates to an adjustable energy-saving lamp. Background Art

[0002] With the development of lighting technology, in the lighting industry, higher requirements are put forward for the luminous efficacy of lamps. The luminous efficacy of a lamp refers to the ratio of the luminous flux value emitted by the lamp measured under specified conditions to the sum of the measured luminous flux values of all light sources in the lamp, which can reflect the degree of light energy loss during the process from the light emitted by the light source to the light emitted from the lamp. As an important energy-saving lighting product, energy-saving lamps have received extensive attention and rapid development. Energy-saving lamps have significant advantages such as high luminous efficiency, low energy consumption, and long lifespan. Compared with traditional incandescent lamps, they can greatly reduce energy consumption under the same lighting effect.

[0003] A Chinese patent document with the publication number CN113606563B discloses an energy-saving lamp support frame that is convenient to adjust, including a support component. The upper end of the support component is fixedly installed with an adapter component, the upper end of the adapter component is fixedly installed with a connection component, the left end of the connection component is fixedly installed with a fixing component, the left end of the fixing component is fixedly installed with two fixing blocks, a first bolt is arranged inside the two fixing blocks, the outer surface of the first bolt is located between the two fixing blocks, and an installation block is arranged. The installation block is fixedly connected to the fixing block through the first bolt. The left end of the installation block is fixedly installed with a lampshade, and wiring pipes are fixedly installed at the front ends of the connection component and the adapter component.

[0004] When the lampshade is adjusted downward, the support rod drives the connecting rod in the placement groove to move upward and rotate inside the placement groove at the same time. The connecting rod drives the rubber wheel on the outer surface of the cylinder to rotate in the first chute. The connecting rod also drives the rectangular rod in the groove to rotate, and at the same time drives the rectangular rod to slide upward in the rectangular groove. Then, while moving upward, the rectangular rod drives the steel wire to pull the support plate to move. The support plate drives the slider to move leftward in the third chute while squeezing the spring to contract. The movement of the slider will drive the connecting block to move, the connecting block drives the support frame to move leftward, and the movement of the support frame drives the rotating cylinder in the slide bar groove to rotate. The extended support frame and support plate can increase the support area between the bottom plate and the ground.

[0005] However, the above-mentioned prior art still has the following deficiencies: When an energy-saving lamp is used in a cold storage, due to the high humidity inside the cold storage and a large amount of water vapor in the air, after the water vapor adheres to the lampshade of the energy-saving lamp, affected by the low-temperature environment inside the cold storage, the water vapor is likely to form frost on the lampshade of the energy-saving lamp. As time goes by, the thickness of the frost gradually increases, thus affecting the lighting effect of the energy-saving lamp. To avoid the thick frost layer from affecting the lighting effect of the energy-saving lamp, it is necessary for the staff to frequently clean the frost on the lampshade, and the cleaning operation is troublesome. Summary of the Invention

[0006] The present invention provides an adjustable energy-saving lamp, aiming to solve the problem in the related art that in order to avoid the influence of a relatively thick ice layer on the lighting effect of the energy-saving lamp, the staff needs to frequently clean the ice on the lampshade.

[0007] The adjustable energy-saving lamp of the present invention includes a lamp and an adjusting member, the lamp is connected to the adjusting member, and further includes a shielding mechanism. The shielding mechanism includes a shielding cover, a shielding member and a feeding member. The shielding cover is connected to the lamp, the shielding member is installed in the shielding cover, the shielding member can shield water vapor, and the feeding member is connected in the shielding cover for supporting the shielding member; the shielding member includes a first frame, a second frame, a third frame and three transparent plates. The first frame, the second frame and the third frame are stacked in sequence from bottom to top, and the three transparent plates are respectively connected in the first frame, the second frame and the third frame. Ice can be formed on the transparent plates in the first frame, the second frame and the third frame in sequence, and under the action of the gravity of the ice, the shielding member can drive the feeding member, so that the first frame and the second frame are separated from the shielding cover one by one, and the third frame stays in the shielding cover and will not fall out of the shielding cover.

[0008] Beneficial effects: During use, water vapor first adheres to the transparent plate in the first frame and forms ice. As the use time increases, the thickness of the ice gradually becomes thicker, so that the gravity of the ice on the first frame and the transparent plate inside it gradually increases, thereby driving the first frame and the transparent plate inside it to gradually move downward and drive the feeding member. After the first frame is separated from the feeding member, the first frame and the transparent plate inside it drive the ice to fall. At this time, the second frame and the transparent plate inside it continue to shield the shielding cover. Ice is formed on the second frame and the transparent plate inside it. After the second frame and the transparent plate inside it fall under the action of the gravity of the ice, the third frame and the transparent plate inside it shield the shielding cover, and the third frame will not fall out of the shielding cover. Finally, the third frame and the transparent plate inside it are taken out of the shielding cover, and a shielding member without attached ice is replaced, thereby reducing the cleaning frequency of the staff for ice.

[0009] Preferably, two feeding members are provided, and the two feeding members are respectively connected to the left and right sides of the inner bottom of the shielding cover. The feeding member includes a rotating shaft and a supporting part. The rotating shaft is rotatably connected in the shielding cover, the supporting part is connected to the outside of the rotating shaft, the supporting part is in a disc shape, and there are three protrusions on the outside of the supporting part. The first frame, the second frame and the third frame can be supported in sequence through the three protrusions.

[0010] The effect is that when the first frame, the second frame and the third frame move downward, they can push the supporting part to drive the rotating shaft to rotate, so that the first frame and the second frame can be separated from the supporting part one by one.

[0011] Preferably, the feeding member further includes a mounting portion, a first elastic portion, a first friction portion, a second elastic portion, a second friction portion, a blocking portion, and a third friction portion. The mounting portion is connected inside the shielding cover. The first friction portion and the second friction portion are both limitedly slidably connected inside the mounting portion. The first elastic portion is connected between the first friction portion and the mounting portion. The second elastic portion is connected between the second friction portion and the mounting portion. Both the first elastic portion and the second elastic portion are in a compressed state. The axial pressure received by the first elastic portion is greater than the axial pressure received by the second elastic portion. The third friction portion is connected to the rotating shaft, and the third friction portion is in contact with the first friction portion.

[0012] The effect is that: under the action of the first elastic portion and the second elastic portion, the frictional forces generated by the third friction portion contacting the first friction portion and the second friction portion in sequence can provide supporting forces to the entire feeding member and the feeding member lacking the first frame and the transparent plate inside it in sequence.

[0013] Preferably, two blocking portions are provided. The two blocking portions are respectively connected to both ends of the mounting portion and can limit and block the third friction portion.

[0014] The effect is that: after the second frame and the transparent plate inside it fall under the action of the gravity of the ice and frost, by blocking the third friction portion through the blocking portion, the rotating shaft can be stopped, so that the supporting portion can support the third frame and the transparent plate inside it, so that the third frame and the transparent plate inside it will not fall from inside the shielding cover due to the gravity of the ice and frost.

[0015] Preferably, the shielding mechanism further includes two sealing portions and two third elastic portions. The two sealing portions are respectively rotatably connected to the left and right ends of the bottom of the shielding cover. One end of the sealing portion is in contact with the bottom of the shielding member. The third elastic portion is connected between the sealing portion and the shielding cover.

[0016] The effect is that: through the sealing portion and the third elastic portion, water vapor can be prevented from entering the shielding cover through the gaps between the left and right sides of the shielding member and the left and right inner walls of the shielding cover.

[0017] Preferably, an installation opening is provided on the front side of the shielding cover for placing the shielding member into the shielding cover. A plugging portion is inserted into the installation opening for plugging the installation opening.

[0018] Preferably, the shielding mechanism further includes a connecting member. The connecting member includes a lapping portion and a locking portion. The lapping portion is rotatably connected to the top of the shielding cover. Rotating the lapping portion can make the bottom of the lapping portion contact the lamp. The locking portion is inserted into the lapping portion, and the locking portion can penetrate through the lapping portion and be inserted into the lamp.

[0019] Preferably, a collecting member is further included. The collecting member includes a transmission structure and a collecting rod. The transmission structure is connected between the rotating shafts in the two feeding members. The collecting rod is connected to the shielding cover. An opening one is provided on the first frame, and an opening two is provided on the second frame.

[0020] Preferably, the transmission structure includes a transmission belt and two transmission wheels. The two transmission wheels are respectively connected to the rotating shafts in the two feeding members. The transmission belt is drivingly connected between the two transmission wheels, and the transmission belt is in an 8-shaped configuration, enabling the two transmission wheels to rotate in opposite directions.

[0021] Preferably, the collecting rod includes a vertical section, an inclined section, and a connecting section. The vertical section is located directly below the first opening. The inclined section has a high end and a low end. The high end of the inclined section is connected to the vertical section, and the low end of the inclined section extends away from the shielding cover. One end of the connecting section is connected to the inclined section, and the other end of the connecting section is connected to the shielding cover.

[0022] The beneficial effects of the present invention are as follows:

[0023] 1. After long-term use, frost will first form on the transparent plate in the first housing. Driven by the gravity of the frost, the shielding member moves downward, causing the shielding member to drive the feeding member. After the first housing and the transparent plate inside it fall off, frost will form on the transparent plate in the second housing until the second housing and the transparent plate inside it fall off. Finally, frost forms on the transparent plate in the third housing. At this time, the feeding member is locked and cannot operate, causing the third housing to remain in the shielding cover, waiting for the staff to disassemble and replace the shielding member, thereby reducing the frequency of ice cleaning by the staff.

[0024] 2. Under the action of the second elastic part and the first elastic part, the frictional force between the second friction part and the third friction part is less than the frictional force between the third friction part and the first friction part. Thus, after the frost on the transparent plate in the second housing reaches a similar weight to the frost on the transparent plate in the first housing, it can break away from the feeding member. Furthermore, when the second housing and the first housing fall, the thickness of the frost on the transparent plates inside them is similar, ensuring the lighting effect of the lamp body.

[0035] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation to the present invention.

[0036] As Figures 1 to 8 shown, the adjustable energy-saving lamp of the present invention includes a lighting fixture 1, an adjusting member 2, a shielding mechanism 3 and a collection member 4. The lighting fixture 1 is used for illuminating the cold storage. The adjusting member 2 is connected to the inner top wall of the cold storage. The lighting fixture 1 is connected to the adjusting member 2. The adjusting member 2 can adjust the installation position of the lighting fixture 1. The shielding mechanism 3 is connected to the lighting fixture 1 and is used for shielding water vapor so that the water vapor adheres to the shielding mechanism 3 and forms ice. And when the thickness of the ice reaches a certain degree, the gravity of the ice can drive the shielding mechanism 3 to automatically disassemble and fall, so as to remove the ice. The collection member 4 is connected to the shielding mechanism 3 and is used for collecting the part of the shielding mechanism 3 that disassembles and falls to avoid injuring the staff passing below.

[0037] The lamp 1 emits light in the cold storage to illuminate the cold storage. The water vapor in the cold storage adheres to the shielding mechanism 3, and the shielding mechanism 3 blocks the water vapor. In the low-temperature environment of the cold storage, the water vapor gradually forms ice on the shielding mechanism 3. After the ice reaches a certain thickness, the shielding mechanism 3 automatically disintegrates and falls due to the gravity of the ice, thereby removing the ice. The part of the shielding mechanism 3 that disintegrates and falls is collected by the collecting member 4 to avoid injuring the staff passing below.

[0038] As Figure 1 and Figure 2 shown, the lamp 1 includes a lamp body 11, a lamp cover 12 and a connecting portion 13. The lamp cover 12 is connected to the bottom of the lamp body 11 to protect the bottom of the lamp body 11. After the lamp body 11 is powered on, it can emit light to illuminate the cold storage. The connecting portion 13 is connected to the top of the lamp body 11 to connect the lamp body 11 in the cold storage. The adjusting member 2 includes a guide rail 21 and a lead screw 22. The guide rail 21 is connected to the inner top wall of the cold storage. The connecting portion 13 is slidably connected in the guide rail 21. The lead screw 22 is rotatably connected in the guide rail 21. The connecting portion 13 is threadedly connected to the lead screw 22. By driving the lead screw 22 to rotate, the connecting portion 13 can be driven to move along the length direction of the guide rail 21, thereby adjusting the installation position of the lamp 1.

[0039] As Figure 1 , Figures 3 to 6 shown, the shielding mechanism 3 includes a shielding cover 31, a connecting member 32, a plugging portion 33, a housing 34, a shielding member 35, a discharging member 36, a sealing portion 37 and an elastic portion 38. The shielding cover 31 is sleeved outside the lamp body 11. The connecting member 32 is installed on the shielding cover 31 to connect the shielding cover 31 to the lamp body 11. An installation opening 311 is provided on the front side of the shielding cover 31 for putting the shielding member 35 into the shielding cover 31. The plugging portion 33 is inserted into the installation opening 311 to plug the installation opening 311 to prevent water vapor from entering the shielding cover 31 through the installation opening 311. Magnetic blocks are connected to both the plugging portion 33 and the shielding cover 31, and the two magnetic blocks are magnetically adsorbed to fix the plugging portion 33 on the shielding cover 31 through the two magnetic blocks. The housing 34 is connected to the front side of the shielding cover 31. The shielding member 35 is inserted into the shielding cover 31 to block the water vapor on the vertical path when the light is emitted, so as to prevent the water vapor from adhering to the lamp cover 12;

[0040] The feeding members 36 are provided in two numbers, and the two feeding members 36 are respectively connected to the left and right sides of the inner bottom of the shielding cover 31. The two feeding members 36 can support the shielding member 35. When the ice thickness at the bottom of the shielding member 35 gradually increases, the two feeding members 36 are driven to move by the gravity of the ice, so that the shielding member 35 automatically disintegrates. The disintegrated and fallen shielding member 35 can drive the ice to fall and be collected by the collecting member 4, so that the ice is moved away from the vertical path when the light is emitted, and there is no need to frequently clean the ice. The sealing parts 37 are provided in two numbers, and the two sealing parts 37 are respectively rotatably connected to the left and right ends of the bottom of the shielding cover 31. One end of the sealing part 37 is in contact with the bottom of the shielding member 35 to prevent water vapor from entering the shielding cover 31 through the gaps between the left and right sides of the shielding member 35 and the left and right sides of the inner wall of the shielding cover 31. The third elastic part 38 is connected between the sealing part 37 and the shielding cover 31. The third elastic part 38 is a torsion spring for driving the sealing part 37 to reset.

[0041] The shielding member 35 shields the water vapor on the vertical path when the light is emitted, so that the water vapor adheres to the shielding member 35 and gradually forms ice. As the ice thickness increases, the gravity of the ice on the shielding member 35 also gradually increases, so that the shielding member 35 gradually moves downward and drives the two feeding members 36. When the shielding member 35 moves downward, it pushes the sealing part 37 to flip and twist the third elastic part 38. After a part of the shielding member 35 is separated from the feeding member 36, it automatically disintegrates and falls. The disintegrated and fallen part of the shielding member 35 drives the ice to fall. After the sealing part 37 is separated from the disintegrated and fallen part of the shielding member 35, under the action of the third elastic part 38, it drives the sealing part 37 to reset and contacts the bottom of other parts of the shielding member 35, so as to continue to seal the gaps between the left and right sides of the shielding member 35 and the left and right sides of the inner wall of the shielding cover 31. When the disintegrated and fallen part of the shielding member 35 drives the ice to fall, the collecting member 4 collects the disintegrated and fallen part of the shielding member 35, and moves the disintegrated and fallen part of the shielding member 35 and the ice on its surface away from the vertical path when the light is emitted, so as to prevent the disintegrated and fallen part of the shielding member 35 and the ice on its surface from injuring the passing staff below.

[0042] Continue to refer to Figure 1 、 Figures 3 to 6As shown, the connecting member 32 includes a lapping portion 321 and a locking portion 322. The lapping portion 321 is rotatably connected to the top of the shielding cover 31. Rotating the lapping portion 321 can make the bottom of the lapping portion 321 contact the lamp body 11. The locking portion 322 is inserted into the lapping portion 321, and the locking portion 322 can penetrate through the lapping portion 321 and be inserted into the lamp body 11, so as to fix the shielding cover 31 on the lamp body 11. The shielding member 35 includes a first frame 351, a second frame 352, a third frame 353 and a transparent plate 354. The second frame 352 is placed on the top of the first frame 351, the third frame 353 is placed on the top of the second frame 352. There are three transparent plates 354, and the three transparent plates 354 are respectively connected inside the first frame 351, the second frame 352 and the third frame 353. When the light of the lamp body 11 emits downward, it can pass through the three transparent plates 354 in sequence, so as to realize the lighting in the cold storage. The left and right ends of the first frame 351, the second frame 352 and the third frame 353 are all triangular, so as to facilitate the discharging member 36 to discharge the first frame 351, the second frame 352 and the third frame 353 downward in sequence.

[0043] Stack the first frame 351, the second frame 352 and the third frame 353 from bottom to top in sequence to form the shielding member 35. Place the shielding member 35 into the shielding cover 31 through the installation opening 311 on the front side of the shielding cover 31, so that the discharging member 36 supports the first frame 351, thereby supporting the entire shielding member 35. One end of the sealing portion 37 is in contact with the bottom of the first frame 351. At this time, insert the blocking portion 33 into the installation opening 311, and perform magnetic adsorption through two magnetic blocks on the blocking portion 33 and the shielding cover 31, so as to block and seal the installation opening 311 by the blocking portion 33.

[0044] During use, water vapor adheres to the lower surface of the transparent plate 354 within the first frame 351 and gradually forms frost in the low-temperature environment of the cold storage. As time goes by, the thickness of the frost gradually increases, and the gravity exerted on the first frame 351 also gradually becomes larger. At this time, under the action of the gravity of the frost, the entire shielding member 35 gradually moves downward and drives the feeding member 36. After the first frame 351 is separated from the feeding member 36, the first frame 351 pushes the sealing portion 37 to flip until the first frame 351 is separated from the sealing portion 37. After the first frame 351 is separated from the sealing portion 37, the collecting member 4 supports and collects the first frame 351 to prevent it from injuring the staff passing below. At the same time, the sealing portion 37 is reset under the action of the third elastic portion 38 so that the sealing portion 37 contacts the bottom of the second frame 352. At this time, water vapor continues to adhere to the bottom of the transparent plate 354 within the second frame 352 and forms frost. As time increases, the thickness of the frost gradually thickens and the gravity gradually increases. The second frame 352 continues to fall onto the collecting member 4 under the action of the gravity of the frost, and causes the third frame 353 to move downward, and is supported by the feeding member 36 so that the third frame 353 stays within the shielding cover 31. At this time, the feeding member 36 stops feeding the third frame 353. After the staff observes that both the first frame 351 and the second frame 352 have fallen onto the collecting member 4, they can manually remove the first frame 351 and the second frame 352, and open the blocking portion 33 to push the third frame 353 upward, thereby removing the third frame 353 from the installation opening 311. Subsequently, replace the shielding member 35 without attached frost and reinstall the blocking portion 33 into the installation opening 311 to reduce the frequency of the staff cleaning the frost.

[0045] Continue to refer to Figure 1 、 Figures 3 to 6As shown, the feeding member 36 includes a rotating shaft 361, a supporting portion 362, a mounting portion 363, a first elastic portion 364, a first friction portion 365, a second elastic portion 366, a second friction portion 367, a blocking portion 368 and a third friction portion 369. The rotating shaft 361 is rotatably connected within the shielding cover 31. The supporting portion 362 is connected to the outside of the rotating shaft 361. The supporting portion 362 is disc-shaped, and there are three protrusions on the outside of the supporting portion 362. Through the three protrusions, the first frame 351, the second frame 352 and the third frame 353 can be supported in sequence. The mounting portion 363 is connected within the shielding cover 31. Both the first friction portion 365 and the second friction portion 367 are limited and slidably connected within the mounting portion 363. The first elastic portion 364 is connected between the first friction portion 365 and the mounting portion 363. The second elastic portion 366 is connected between the second friction portion 367 and the mounting portion 363. Both the first elastic portion 364 and the second elastic portion 366 are compression springs, and both the first elastic portion 364 and the second elastic portion 366 are in a compressed state. The axial pressure received by the first elastic portion 364 is greater than the axial pressure received by the second elastic portion 366. The third friction portion 369 is connected to the rotating shaft 361, and the third friction portion 369 is in contact with the first friction portion 365. At this time, under the action of the first elastic portion 364, the first friction portion 365 is in close contact with the third friction portion 369. Thus, when the protrusion on the supporting portion 362 contacts the bottom of the first frame 351, under the action of the first elastic portion 364, through the friction force between the first friction portion 365 and the third friction portion 369, a supporting force is provided for the entire shielding member 35 to prevent the shielding member 35 from separating from the supporting portion 362 under its own gravity;

[0046] When the first frame 351 moves downward, it pushes the supporting portion 362 to cause the rotating shaft 361 to rotate, thereby driving the third friction portion 369 to move arcuately. After the first frame 351 separates from the supporting portion 362, the third friction portion 369 moves onto the second friction portion 367. At this time, under the elastic force of the second elastic portion 366, the second friction portion 367 is in close contact with the third friction portion 369. Through the friction force between the second friction portion 367 and the third friction portion 369, a supporting force is provided for the remaining second frame 352, third frame 353 and the transparent plate 354 within the second frame 352 and the third frame 353. Under the action of the second elastic portion 366 and the first elastic portion 364, the friction force between the second friction portion 367 and the third friction portion 369 is made less than the friction force between the third friction portion 369 and the first friction portion 365. Thus, after the frost on the transparent plate 354 within the second frame 352 reaches a similar weight to the frost on the transparent plate 354 within the first frame 351, it can separate from the feeding member 36. Furthermore, when the second frame 352 and the first frame 351 fall, the thickness of the frost on the internal transparent plate 354 is similar to ensure the lighting effect of the lamp body 11;

[0047] There are two blocking parts 368, which are respectively connected to both ends of the mounting part 363. The two blocking parts 368 can limit and block the third friction part 369, so that after the first frame 351 and the second frame 352 fall in sequence, the third friction part 369 will no longer be affected by the gravity of the ice and frost on the third frame 353 under the action of the blocking part 368, and drive the rotating shaft 361 to rotate. As a result, the third frame 353 will not fall off the shielding cover 31. The bottom of the shielding cover 31 is blocked by the third frame 353 and the transparent plate 354 inside it to prevent water vapor from entering from below the shielding cover 31 and adhering to the lamp cover 12.

[0048] During use, water vapor adheres to the lower surface of the transparent plate 354 in the first frame 351 and gradually forms ice and frost. As time goes by, the thickness of the ice and frost gradually increases, and the gravity received by the first frame 351 also gradually becomes larger. At this time, under the action of the gravity of the ice and frost, the entire shielding part 35 gradually moves downward. When the first frame 351 moves downward, it pushes the supporting part 362, so that the rotating shaft 361 rotates, thereby driving the third friction part 369 to move arcuately. After the first frame 351 is separated from the supporting part 362, the third friction part 369 moves onto the second friction part 367. At this time, under the elastic force of the second elastic part 366, the second friction part 367 is in close contact with the third friction part 369. Through the frictional force between the second friction part 367 and the third friction part 369, a supporting force is provided for the remaining second frame 352, third frame 353, and the transparent plates 354 in the second frame 352 and the third frame 353. After the second frame 352 falls under the action of the gravity of the ice and frost, the blocking part 368 blocks the third friction part 369, so that the third friction part 369 will no longer be affected by the gravity of the ice and frost on the third frame 353 and drive the rotating shaft 361 to rotate, so that the third frame 353 will not fall off the shielding cover 31. After the staff observes that both the first frame 351 and the second frame 352 have fallen onto the collecting part 4, the first frame 351 and the second frame 352 can be manually removed, and the blocking part 33 is opened to push the third frame 353 upward, so as to take out the third frame 353 from the mounting opening 311. Subsequently, a shielding part 35 without adhered ice and frost is replaced, and the blocking part 33 is installed into the mounting opening 311 again.

[0049] Such as Figure 3 , Figure 7 and Figure 8As shown in the figure, the collecting member 4 includes a transmission structure 41 and a collecting rod 42. The transmission structure 41 includes a transmission belt and two transmission wheels. The two transmission wheels are respectively connected to the rotating shafts 361 in the two feeding members 36. The transmission belt is drivingly connected between the two transmission wheels, and the transmission belt is in an 8-shaped configuration, so that the two transmission wheels can rotate in opposite directions, thereby enabling the two feeding members 36 to feed synchronously. At this time, the dropped frame one 351 and frame two 352 can be collected by the collecting rod 42. The transmission structure 41 is located inside the housing 34 to prevent frost from condensing on the transmission structure 41 and affecting the normal operation of the transmission structure 41. An opening one 3511 is provided on the frame one 351, and an opening two 3521 is provided on the frame two 352. The collecting rod 42 includes a vertical section 421, an inclined section 422, and a connecting section 423. The vertical section 421 is located directly below the opening one 3511. The inclined section 422 has a high end and a low end. The high end of the inclined section 422 is connected to the vertical section 421, and the low end of the inclined section 422 extends in a direction away from the shielding cover 31. One end of the connecting section 423 is connected to the inclined section 422, and the other end of the connecting section 423 is connected to the shielding cover 31. When the frame one 351 and the frame two 352 drop in sequence, they are sequentially sleeved on the vertical section 421 through the opening one 3511 and the opening two 3521. After the frame one 351 and the frame two 352 pass over the vertical section 421, under the blocking and guiding of the inclined section 422, the frame one 351 and the frame two 352 are flipped from a horizontal state to a vertical state and move along the length direction of the inclined section 422 until the frame one 351 and the frame two 352 are separated from below the shielding cover 31 to avoid blocking the vertical path when the light is emitted.

[0050] Working principle:

[0051] Insert the shielding member 35 into the shielding cover 31 from the mounting opening 311 and support it by the two feeding members 36. Subsequently, insert the blocking portion 33 into the mounting opening 311 to block the mounting opening 311.

[0052] During use, water vapor adheres to the lower surface of the transparent plate 354 in the frame one 351 and gradually forms frost. As time goes by, the thickness of the frost gradually increases, and the gravity of the frame one 351 also gradually becomes larger. At this time, under the action of the gravity of the frost, the frame one 351 is driven to move downward. When the frame one 351 moves downward, it pushes the supporting portion 362 to rotate the rotating shaft 361, thereby driving the friction portion three 369 to move in an arc. After the frame one 351 is separated from the supporting portion 362, the friction portion three 369 moves onto the friction portion two 367. At this time, under the elastic force of the elastic portion two 366, the friction portion two 367 is in close contact with the friction portion three 369. Through the friction between the friction portion two 367 and the friction portion three 369, a supporting force is provided for the remaining frame two 352, frame three 353, and the transparent plates 354 in the frame two 352 and frame three 353.

[0053] Under the action of the second elastic part 366 and the first elastic part 364, the frictional force between the second friction part 367 and the third friction part 369 is made smaller than the frictional force between the third friction part 369 and the first friction part 365, so that after the frost on the transparent plate 354 in the second frame 352 and the frost on the transparent plate 354 in the first frame 351 reach a similar weight, they can break away from the feeding part 36.

[0054] After the second frame 352 falls under the action of the gravity of the frost, the blocking part 368 blocks the third friction part 369, so that the third friction part 369 is no longer affected by the gravity of the frost on the third frame 353 and drives the rotating shaft 361 to rotate, so that the third frame 353 will not fall from the shielding cover 31.

[0055] When the first frame 351 and the second frame 352 fall in sequence, the two feeding parts 36 are synchronously operated through the transmission structure 41. After the first frame 351 and the second frame 352 are separated from the shielding cover 31, they are sleeved on the vertical section 421 through the first opening 3511 and the second opening 3521 in sequence. After the first frame 351 and the second frame 352 cross the vertical section 421, under the blocking and guiding of the inclined section 422, the first frame 351 and the second frame 352 are flipped from the horizontal state to the vertical state and move along the length direction of the inclined section 422 until the first frame 351 and the second frame 352 are separated from below the shielding cover 31.

[0056] After the staff observes that both the first frame 351 and the second frame 352 have fallen onto the collecting rod 42, the first frame 351 and the second frame 352 can be manually removed, and the blocking part 33 is opened to push the third frame 353 upward, so as to take out the third frame 353 from the installation opening 311, and the rotating shaft 361 on one of the feeding parts 36 is rotated. Under the action of the transmission structure 41, the two feeding parts 36 are reset. Subsequently, the shielding part 35 without attached frost is replaced, and the blocking part 33 is installed into the installation opening 311 again.
