Technical Field

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

[0002] With the development of lighting technology, higher requirements are put forward for the lamp efficiency in the lamp industry. Lamp efficiency 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 ​​emitted by all light sources in the lamp. It can reflect the degree of light energy loss from the light source to the light emitted from the lamp. As an important energy-saving lighting product, energy-saving lamps have received widespread attention and rapid development. Energy-saving lamps have significant advantages such as high luminous efficiency, low energy consumption and long life. Compared with traditional incandescent lamps, they can greatly reduce energy consumption under the same lighting effect.

[0003] A Chinese patent document with announcement number CN113606563B discloses an energy-saving lamp support frame that is easy to adjust, including a support component, a connecting component is fixedly installed on the upper end of the support component, a connecting component is fixedly installed on the upper end of the connecting component, a fixing component is fixedly installed on the left end of the connecting component, two fixing blocks are fixedly installed on the left end of the fixing component, 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 a mounting block is arranged, the mounting block is fixedly connected to the fixing block by the first bolt, a lampshade is fixedly installed on the left end of the mounting block, and wiring tubes are fixedly installed on the front ends of the connecting component and the connecting 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, the connecting rod drives the rubber wheel on the outer surface of the cylinder to rotate in the first slide groove, and the connecting rod simultaneously drives the rectangular rod in the groove to rotate, and drives the rectangular rod to slide upward in the rectangular groove, and then the rectangular rod moves upward and drives the steel wire to pull the support plate to move, the support plate drives the slider to move to the left in the third slide groove while squeezing the spring to contract, and the movement of the slider will drive the connecting block to move, and the connecting block drives the support frame to move to the left, and the movement of the support frame drives the rotating cylinder in the slide groove to rotate, and the extended support frame and support plate can increase the supporting area between the base plate and the ground.

[0005] However, the above-mentioned prior art still has the following shortcomings: when the energy-saving lamp is used in a cold storage, due to the high humidity inside the cold storage, there is still a large amount of water vapor in the air. After the water vapor adheres to the lampshade of the energy-saving lamp, it is easily formed into frost on the lampshade under the influence of the low temperature environment inside the cold storage. As time goes by, the thickness of the frost gradually increases, thereby affecting the lighting effect of the energy-saving lamp. In order to avoid the thick frost layer affecting the lighting effect of the energy-saving lamp, the staff needs to frequently clean the frost on the lampshade, which is troublesome to clean. Summary of the invention

[0008] Beneficial effect: during use, water vapor first adheres to the transparent plate in frame one and forms frost. As the use time increases, the thickness of the frost gradually becomes thicker, so that the gravity of the frost on frame one and the transparent plate inside it gradually increases, thereby driving frame one and the transparent plate inside it to gradually move downward and drive the discharge piece. After frame one is separated from the discharge piece, frame one and the transparent plate inside it drive the frost to be discharged. At this time, frame two and the transparent plate inside it continue to shield the shielding cover. Frost is formed on frame two and the transparent plate inside it. After frame two and the transparent plate inside it fall under the action of the gravity of the frost, frame three and the transparent plate inside it shield the shielding cover, and frame three will not fall from the shielding cover. Finally, frame three and the transparent plate inside it are taken out of the shielding cover, and replaced with a shielding piece without frost attached, thereby reducing the frequency of frost cleaning by staff.

[0009] Preferably, there are two material discharge members, which are respectively connected to the left and right sides of the inner bottom of the shielding cover.

[0012] The effect is that under the action of elastic part 1 and elastic part 2, the friction force generated by friction part 3 contacting friction part 1 and friction part 2 in sequence can provide support force for the entire discharge piece and the discharge piece behind the missing frame 1 and the transparent plate inside it.

[0013] Preferably, the blocking parts are provided in two, and the two blocking parts are respectively connected to the two ends of the mounting part, and can provide three-position blocking for the friction part.

[0014] The effect is that after the frame body 2 and the transparent plate inside it fall due to the gravity of frost, the friction part 3 is blocked by the blocking part, so that the rotation of the shaft can be stopped, so that the supporting part supports the frame body 3 and the transparent plate inside it, so that the frame body 3 and the transparent plate inside it will not fall out of the shielding cover due to the gravity of frost.

[0015] Preferably, the shielding mechanism also includes two sealing parts and two elastic parts three, the two sealing parts are rotatably connected to the left and right ends of the bottom of the shielding cover respectively, one end of the sealing part contacts the bottom of the shielding member, and the elastic part three is connected between the sealing part and the shielding cover.

[0016] The effect is that the sealing part and the elastic part 3 are used to prevent water vapor from entering the shielding cover through the gaps between the left and right sides of the shielding member and the left and right sides of the inner wall of the shielding cover.

[0017] Preferably, a mounting opening is provided on the front side of the shielding cover for placing the shielding member into the shielding cover, and a blocking portion is inserted into the mounting opening for blocking the mounting opening.

[0018] Preferably, the shielding mechanism also includes a connecting piece, which includes a lap joint and a locking piece. The lap joint is rotatably connected to the top of the shielding cover, and rotating the lap joint can make the bottom of the lap joint contact with the lamp.

[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 material discharge members, the transmission belt is connected between the two transmission wheels, and the transmission belt is in an 8 shape so that the two transmission wheels can 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 opening one, the inclined section has a high end and a low end, the high end of the inclined section is connected to the vertical section, the low end of the inclined section extends in a direction 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: 1. After long-term use, frost will first form on the transparent plate in frame one, and the gravity of the frost will drive the shielding member to move down, so that the shielding member drives the discharge member. After frame one and the transparent plate inside it fall off, frost will form on the transparent plate in frame two, until frame two and the transparent plate inside it fall off, and finally frost will form on the transparent plate in frame three. At this time, the discharge member is locked and cannot operate, so that frame three is stranded in the shielding cover, waiting for the staff to disassemble and replace the shielding member, thereby reducing the frequency of frost cleaning by the staff.

[0023] 2. Under the action of the elastic part 2 and the elastic part 1, the friction force between the friction part 2 and the friction part 3 is smaller than the friction force between the friction part 3 and the friction part 1, so that the frost on the transparent plate in the frame 2 and the frost on the transparent plate in the frame 1 can be separated from the discharge piece after reaching a similar weight, and then when the frame 2 and the frame 1 fall, the thickness of the frost on their internal transparent plates is similar, so as to ensure the lighting effect of the lamp body.

[0033] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0034] like Figures 1 to 8 As shown, the adjustable energy-saving lamp of the present invention comprises a lamp 1, an adjusting member 2, a shielding mechanism 3 and a collecting member 4. The lamp 1 is used for lighting the inside of a cold storage. The adjusting member 2 is connected to the inner top wall of the cold storage. The lamp 1 is connected to the adjusting member 2. The adjusting member 2 can adjust the installation position of the lamp 1. The shielding mechanism 3 is connected to the lamp 1 to shield water vapor so that the water vapor adheres to the shielding mechanism 3 and forms frost. When the thickness of the frost reaches a certain level, the gravity of the frost can drive the shielding mechanism 3 to automatically disintegrate and fall, thereby removing the frost. The collecting member 4 is connected to the shielding mechanism 3 to collect the disintegrated and fallen parts of the shielding mechanism 3 to avoid injuring the staff passing below.

[0035] 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 frost on the shielding mechanism 3. When the frost reaches a certain thickness, the gravity of the frost drives the shielding mechanism 3 to automatically disintegrate and fall, thereby removing the frost. The disintegrated and fallen part of the shielding mechanism 3 is collected by the collecting component 4 to avoid injuring the staff passing below.

[0036] like Figure 1 and Figure 2 As shown, the lamp 1 includes a lamp body 11, a lampshade 12 and a connecting portion 13. The lampshade 12 is connected to the bottom of the lamp body 11 to protect the bottom of the lamp body 11. The lamp body 11 can emit light after being energized, thereby illuminating the cold storage. The connecting portion 13 is connected to the top of the lamp body 11 to connect the lamp body 11 to the cold storage. The adjusting member 2 includes a guide rail 21 and a screw rod 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 screw rod 22 is rotatably connected in the guide rail 21. The connecting portion 13 is threadedly connected to the screw rod 22. By driving the screw rod 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.

[0037] like Figure 1 , Figures 3 to 6 As shown, the shielding mechanism 3 includes a shielding cover 31, a connecting piece 32, a blocking portion 33, a shell 34, a shielding piece 35, a discharge piece 36, a sealing portion 37 and an elastic portion 38. The shielding cover 31 is sleeved on the outside of the lamp body 11, and the connecting piece 32 is installed on the shielding cover 31 to connect the shielding cover 31 with the lamp body 11. The front side of the shielding cover 31 is provided with a mounting opening 311 for placing the shielding piece 35 into the shielding cover 31, and the blocking portion 33 is plugged into the mounting opening 311. The installation opening 311 is used to block the installation opening 311 to prevent water vapor from entering the shielding cover 31 from the installation opening 311. The blocking portion 33 and the shielding cover 31 are both connected with magnetic blocks. The two magnetic blocks are magnetically attracted to each other. The blocking portion 33 can be fixed 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 water vapor on the vertical path when the light is emitted to prevent water vapor from adhering to the lampshade 12. There are two discharge members 36, which are respectively connected to the left and right sides of the inner bottom of the shielding cover 31. The two discharge members 36 can support the shielding cover 35. When the thickness of the frost at the bottom of the shielding cover 35 gradually increases, the gravity of the frost drives the two discharge members 36 to move, so that the shielding cover 35 automatically disintegrates. The disintegrated and fallen shielding cover 35 can drive the frost to fall and be collected by the collecting member 4, so that the frost can be moved away from the vertical path when the light is emitted, and there is no need to frequently clean the frost. There are two sealing parts 37, which 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 contacts the bottom of the shielding part 35 to prevent water vapor from entering the shielding cover 31 from the gap between the left and right sides of the shielding part 35 and the left and right sides of the inner wall of the shielding cover 31. The elastic part three 38 is connected between the sealing part 37 and the shielding cover 31. The elastic part three 38 is a torsion spring, which is used to drive the sealing part 37 to reset.

[0038] 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 frost. As the thickness of the frost increases, the gravity of the frost on the shielding member 35 gradually increases, so that the shielding member 35 gradually moves downward and drives the two discharge members 36. When the shielding member 35 moves downward, it pushes the sealing part 37 to flip and twist the elastic part 38. After part of the shielding member 35 is separated from the discharge member 36, it automatically disintegrates and falls. The disintegrated and fallen part of the shielding member 35 drives the frost 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 elastic part three 38, the sealing part 37 is driven to reset and contact the bottom of other parts of the shielding member 35, so as to continue to seal the gap 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 disassembled and falling part of the shielding member 35 drives the frost to fall, the disassembled and falling part of the shielding member 35 is collected by the collecting member 4, and the disassembled and falling part of the shielding member 35 and the frost on its surface are moved away from the vertical path when the light is emitted, so as to avoid the disassembled and falling part of the shielding member 35 and the frost on its surface from hitting the staff passing below.

[0039] Continue to refer Figure 1 , Figures 3 to 6As shown, the connecting member 32 includes a lap portion 321 and a locking portion 322. The lap portion 321 is rotatably connected to the top of the shielding cover 31. Rotating the lap portion 321 can make the bottom of the lap portion 321 contact the lamp body 11. The locking portion 322 is plugged into the lap portion 321, and the locking portion 322 can penetrate the lap portion 321 and be plugged into the lamp body 11, thereby fixing the shielding cover 31 on the lamp body 11. The shielding member 35 includes a frame 1 351, a frame 2 352, a frame 353 and a transparent plate 354. The frame 2 352 is placed on the frame 1 3 51, frame three 353 is placed on the top of frame two 352, three transparent plates 354 are set, and the three transparent plates 354 are respectively connected to frame one 351, frame two 352 and frame three 353. When the light of the lamp body 11 is emitted 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 frame one 351, frame two 352 and frame three 353 are all triangular in shape, so that the material discharge piece 36 can discharge the material of frame one 351, frame two 352 and frame three 353 downward in sequence.

[0040] Frame one 351, frame two 352 and frame three 353 are stacked in sequence from bottom to top to form a shielding member 35, and the shielding member 35 is placed in the shielding cover 31 through the installation opening 311 on the front side of the shielding cover 31, so that the discharge member 36 supports the frame one 351, thereby supporting the entire shielding member 35, and one end of the sealing part 37 is in contact with the bottom of the frame one 351. At this time, the blocking part 33 is inserted into the installation opening 311, and the two magnetic blocks on the sealing part 33 and the shielding cover 31 are magnetically adsorbed, so that the installation opening 311 is blocked and sealed by the blocking part 33.

[0041] During use, water vapor adheres to the lower surface of the transparent plate 354 in the frame 1 351 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 frame 1 351 also gradually increases. At this time, under the action of the gravity of the frost, the entire shielding member 35 gradually moves downward and drives the discharge member 36. After the frame 1 351 is separated from the discharge member 36, the frame 1 351 pushes the sealing portion 37 to flip until the frame 1 351 is separated from the sealing portion 37. After the frame 1 351 is separated from the sealing portion 37, the collecting member 4 supports and collects the frame 1 351 to avoid injuring the staff passing below. At the same time, the sealing portion 37 is reset under the action of the elastic portion 38 to make the sealing portion 37 contact with the bottom of the frame 2 352. At this time, water vapor continues to adhere to the frame 2 351. 353 is removed from the mounting opening 311, and then the shielding member 35 without frost is replaced, and the sealing member 33 is installed in the mounting opening 311 again, so as to reduce the frequency of frost cleaning by the staff.

[0042] Continue to refer Figure 1 , Figures 3 to 6As shown, the discharge member 36 includes a rotating shaft 361, a supporting portion 362, a mounting portion 363, an elastic portion 1 364, a friction portion 1 365, an elastic portion 2 366, a friction portion 2 367, a blocking portion 368 and a friction portion 3 369. The rotating shaft 361 is rotatably connected in the shielding cover 31, the supporting portion 362 is connected to the outer side of the rotating shaft 361, the supporting portion 362 is disc-shaped, and the outer side of the supporting portion 362 has three protrusions, through which the frame 1 351, the frame 2 352 and the frame 3 353 can be supported in sequence, the mounting portion 363 is connected in the shielding cover 31, the friction portion 1 365 and the friction portion 2 367 are both limitedly slidably connected in the mounting portion 363, the elastic portion 1 364 is connected between the friction portion 1 365 and the mounting portion 363, and the elastic portion 2 366 is connected to the friction portion 2 36 7 and the mounting portion 363, the elastic portion 1 364 and the elastic portion 2 366 are both compression springs, and the elastic portion 1 364 and the elastic portion 2 366 are both in a compressed state, the axial pressure on the elastic portion 1 364 is greater than the axial pressure on the elastic portion 2 366, the friction portion 3 369 is connected to the rotating shaft 361, and the friction portion 3 369 is in contact with the friction portion 1 365, at this time, under the action of the elastic portion 1 364, the friction portion 1 365 is in close contact with the friction portion 3 369, so that when the protrusion on the support portion 362 contacts the bottom of the frame 1 351, under the action of the elastic portion 1 364, the friction force between the friction portion 1 365 and the friction portion 3 369 provides support force for the entire shielding member 35, so as to prevent the shielding member 35 from being separated from the support portion 362 under the action of its own gravity; When the frame 1 351 moves downward, the support part 362 is pushed to rotate the rotating shaft 361, thereby driving the friction part 369 to move in an arc shape. After the frame 1 351 is separated from the support part 362, the friction part 369 moves to the friction part 2 367. At this time, under the elastic force of the elastic part 2 366, the friction part 2 367 is in close contact with the friction part 3 369. The friction force between the friction part 2 367 and the friction part 3 369 is used to stabilize the remaining frame 2 352, the frame 3 353, and the transparent plate 350 in the frame 2 352 and the frame 3 353. 4 provides a supporting force, under the action of the second elastic part 366 and the first elastic part 364, so that the friction force between the second friction part 367 and the third friction part 369 is smaller than the friction force between the third friction part 369 and the first friction part 365, so that 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 can be separated from the material discharging member 36 after reaching a similar weight, and further, when the second frame 352 and the first frame 351 fall, the thickness of the frost on the internal transparent plate 354 is similar, so as to ensure the lighting effect of the lamp body 11; There are two blocking parts 368, and the two blocking parts 368 are respectively connected to the two ends of the mounting part 363, which can limit and block the friction part three 369, so that after the frame one 351 and the frame two 352 fall in sequence, the friction part three 369 is no longer affected by the gravity of the frost on the frame three 353 under the action of the blocking parts 368 and drives the rotating shaft 361 to rotate, so that the frame three 353 will not fall from the shielding cover 31, and the bottom of the shielding cover 31 is blocked by the frame three 353 and the transparent plate 354 inside it to prevent water vapor from entering from the bottom of the shielding cover 31 and attaching to the lampshade 12.

[0043] During use, water vapor adheres to the lower surface of the transparent plate 354 in the frame 1 351 and gradually forms frost. As time goes by, the thickness of the frost gradually increases, and the gravity exerted on the frame 1 351 also gradually increases. At this time, under the action of the gravity of the frost, the entire shielding member 35 gradually moves downward. When the frame 1 351 moves downward, it pushes the supporting portion 362 to rotate the rotating shaft 361, thereby driving the friction portion 369 to move in an arc shape. After the frame 1 351 is separated from the supporting portion 362, the friction portion 369 moves to the friction portion 2 367. At this time, under the elastic force of the elastic portion 2 366, the friction portion 2 367 is in close contact with the friction portion 369. The friction between the friction portion 2 367 and the friction portion 369 is used to provide a support for the remaining frame 2 352 and the frame 3 351. 53 and the transparent plate 354 in the frame two 352 and the frame three 353 provide supporting force. After the frame two 352 falls under the action of frost gravity, the blocking portion 368 blocks the friction portion three 369, so that the friction portion three 369 is no longer affected by the frost gravity on the frame three 353 and drives the rotating shaft 361 to rotate, so that the frame three 353 will not fall from the shielding cover 31. After observing that the frame one 351 and the frame two 352 have fallen onto the collecting part 4, the staff can manually remove the frame one 351 and the frame two 352, open the blocking portion 33 to push the frame three 353 upward, so as to remove the frame three 353 from the installation port 311, and then replace the shielding member 35 without frost, and install the blocking portion 33 into the installation port 311 again.

[0044] like Figure 3 , Figure 7 and Figure 8As shown, 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 material discharge members 36. The transmission belt is connected between the two transmission wheels, and the transmission belt is in an 8-shaped shape, so that the two transmission wheels can rotate in opposite directions, so that the two material discharge members 36 can discharge materials synchronously. At this time, the fallen frame 1 351 and frame 2 352 can be collected by the collecting rod 42. The transmission structure 41 is located in the shell 34 to prevent frost from condensing on the transmission structure 41 and affecting the normal operation of the transmission structure 41. The frame 1 351 is provided with an opening 1 3511, and the frame 2 352 is provided with an opening 2 3521. The collecting rod 42 includes a vertical section 421, an inclined section 422 and a connecting section 423. The vertical section 421 is located at the opening 1 3511. Directly below, 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, the low end of the inclined section 422 extends in the 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 1 351 and the frame 2 352 fall down in turn, they are successively mounted on the vertical section 421 through the opening 1 3511 and the opening 2 3521, after the frame 1 351 and the frame 2 352 pass over the vertical section 421, under the blocking guidance of the inclined section 422, the frame 1 351 and the frame 2 352 are flipped from a horizontal state to a vertical state, and move along the length direction of the inclined section 422 until the frame 1 351 and the frame 2 352 are separated from the bottom of the shielding cover 31, so as to avoid blocking the vertical path when the light is emitted.

[0045] Working principle: The shielding member 35 is placed into the shielding cover 31 from the installation opening 311 and supported by the two discharge members 36 . Then, the blocking portion 33 is inserted into the installation opening 311 , so as to block the installation opening 311 .

[0046] During use, water vapor adheres to the lower surface of the transparent plate 354 in the frame 1 351 and gradually forms frost. As time goes by, the thickness of the frost gradually increases, and the gravity exerted on the frame 1 351 also gradually increases. At this time, the frame 1 351 is driven downward by the gravity of the frost. When the frame 1 351 moves downward, it pushes the support part 362 to rotate the rotating shaft 361, thereby driving the friction part 3 369 to move in an arc shape. After the frame 1 351 is separated from the support part 362, the friction part 369 moves to the friction part 2 367. At this time, under the elastic force of the elastic part 2 366, the friction part 2 367 is in close contact with the friction part 3 369. The friction force between the friction part 2 367 and the friction part 3 369 provides support force for the remaining frame 2 352, frame 3 353, and the transparent plate 354 in the frame 2 352 and frame 3 353.

[0047] Under the action of the elastic part 2 366 and the elastic part 1 364, the friction force between the friction part 2 367 and the friction part 3 369 is smaller than the friction force between the friction part 3 369 and the friction part 1 365, so that the frost on the transparent plate 354 in the frame 2 352 and the frost on the transparent plate 354 in the frame 1 351 can be separated from the discharge piece 36 after reaching a similar weight.

[0048] After the frame 2 352 falls under the action of frost gravity, the blocking portion 368 blocks the friction portion 369 so that the friction portion 369 is no longer affected by the frost gravity on the frame 353 and drives the rotating shaft 361 to rotate, so that the frame 353 will not fall from the shielding cover 31.

[0049] When frame 1 351 and frame 2 352 fall down in sequence, the two discharge members 36 are operated synchronously through the transmission structure 41. After frame 1 351 and frame 2 352 are separated from the shielding cover 31, they are successively mounted on the vertical section 421 through opening 1 3511 and opening 2 3521. After frame 1 351 and frame 2 352 pass over the vertical section 421, under the blocking and guidance of the inclined section 422, frame 1 351 and frame 2 352 are flipped from a horizontal state to a vertical state, and move along the length direction of the inclined section 422 until frame 1 351 and frame 2 352 are separated from the bottom of the shielding cover 31.

[0050] After the staff observes that both frame one 351 and frame two 352 have fallen onto the collecting rod 42, they can manually remove frame one 351 and frame two 352, open the blocking portion 33 to push frame three 353 upward, thereby removing frame three 353 from the installation port 311, and rotating the rotating shaft 361 on one of the discharge members 36, so that the two discharge members 36 are reset under the action of the transmission structure 41, and then replace the shielding member 35 without frost attached, and install the blocking portion 33 into the installation port 311 again.

[0051] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
