AI Technical Summary
[0024] Compared with the prior art, the beneficial effects of this application are as follows: By setting up a defogging mechanism and a water absorption mechanism, the output shaft of the motor can be controlled to rotate, driving the threaded rod to rotate inside the first housing, driving the threaded seat to move up and down inside the first housing, and driving the two sets of air outlets to move up and down. The hot air generated by the hot air blown out through the air outlets is blown onto the surface of the glass, performing overall defogging on the glass. When the moving plate moves down, it drives the mounting plate to move down, causing the protrusion to slide inside the first track. The protrusion slides into the second track, and when it passes through the second track, it stretches the first spring. At this time, one side of the water-absorbing sponge contacts the surface of the glass, wiping the fog on the glass surface in advance with the water-absorbing sponge. Then, the hot air blown out by the air outlet further defogging occurs, increasing the defogging efficiency of the defogging mechanism. When passing through the third track, the first spring is always in a stretched state. After reaching the fourth track, the first spring releases its elastic potential energy, driving the protrusion into the fourth track. In the fifth track, one side of the absorbent sponge cannot contact the glass surface. As it moves upward, the air outlet moves in front of the absorbent sponge, so the sponge no longer needs to contact the glass, preventing secondary fogging. At this point, the control motor output shaft drives the moving plate upward, causing the protrusion to slide inside the fifth track. When the protrusion enters the first track from the fifth track, it pushes the limiting member, causing the limiting member to rotate. This causes the rotating plate to rotate, allowing the limiting member to rotate into the second track. After the protrusion has completely passed through the limiting member, the torsion spring releases its elastic potential energy, causing the limiting member to return to the inside of the fifth track, allowing the protrusion to move into the second track next time. This solves the problem that the resistance wire or heating film needs to slowly heat the glass, resulting in low defogging efficiency. To improve defogging efficiency, the resistance wire or heating film needs to be kept in working condition for continuous defogging of the glass, resulting in high energy consumption due to the long-term operation of the electric heating device.

Description
Technical Field
[0001] This application relates to the field of display cabinets, and more specifically, to a moisture-proof and dehumidifying display cabinet with automatic defogging function. Background Technology
[0002] A display case is a specialized device designed to display, protect, and highlight items. It allows viewers to clearly see the items inside through a transparent or semi-transparent viewing interface (such as glass). During use, due to the sealed structure of the display case, a temperature difference occurs between the inside and outside of the case, causing fogging to form on the glass surface. A defogging device is then required to remove the fog.
[0003] However, existing dehumidifying display cabinets with automatic defogging function still have the following shortcomings in use: Most existing dehumidifying display cabinets with automatic defogging function remove fog by embedding a heating resistance wire or heating film inside the glass and heating the glass. This method has low defogging efficiency because the resistance wire or heating film needs to heat the glass slowly. In order to improve the defogging efficiency, the resistance wire or heating film needs to be kept in working state at all times to continuously remove fog from the glass. The electric heating device is working for a long time, which consumes a lot of energy. Utility Model Content
[0004] To overcome the above shortcomings, this application provides a dehumidifying display cabinet with automatic defogging function, which aims to improve the problem that the defogging efficiency is low because the resistance wire or heating film needs to slowly heat the glass. In order to improve the defogging efficiency, the resistance wire or heating film needs to be kept in working state at all times to continuously defog the glass, which results in a large energy consumption due to the long-term operation of the electric heating device.
[0005] This application provides a moisture-proof and dehumidifying display cabinet with automatic defogging function, including a display cabinet body, a glass panel embedded on one side of the display cabinet body, a defogging mechanism for defogging the glass inside the display cabinet body, a water absorption mechanism for absorbing fog on the glass surface inside the display cabinet body, and a humidity sensor inside the display cabinet body. When fog is generated on the glass, the humidity sensor sends a signal to control the motor and hot air blower to work. The humidity sensor is prior art and will not be described in detail here. The defogging mechanism includes a hot air blower connected inside the display case body. Both output ends of the hot air blower are connected to air outlets, and the input end of the hot air blower is connected to the outside of the display case. It can heat the air outside the display case and blow the hot air out through the air outlets to defog the glass. The output end of the hot air blower is connected to the air outlet through a pipe. The pipe is long enough to allow the air outlet to move up and down inside the display case body.
[0006] In one specific implementation, a first housing is connected inside the display cabinet body, a motor is connected to the top of the display cabinet body, the output shaft of the motor passes through the first housing and is connected to a screw, and the other end of the screw is rotatably connected inside the first housing.
[0007] In the above implementation process, by setting up a motor, the output shaft of the motor can be controlled to rotate, thereby driving the threaded rod to rotate inside the first housing.
[0008] In one specific implementation, the outer surface of the screw is threadedly connected to a threaded seat, which is slidably connected inside the first housing.
[0009] In the above implementation process, by setting the screw, the threaded seat can be driven to move up and down inside the first housing when the screw rotates.
[0010] In one specific implementation, a movable plate is connected to one side of the threaded seat, and the movable plate is connected to the bottom of the two sets of air outlets.
[0011] In the above implementation process, by setting the threaded seat, the moving plate can be driven to move up and down when the threaded seat moves, which in turn drives the two sets of air outlets to move up and down. The hot air blown out of the air outlets can then be used to defog the glass as a whole.
[0012] In one specific implementation, a second housing is connected inside the main body of the display cabinet, a vertical rod is connected inside the second housing, and a sliding member is slidably connected to the outer surface of the vertical rod, the sliding member being connected to one side of the movable plate.
[0013] In the above implementation process, by setting the vertical rod, the sliding member can be driven to move up and down inside the second housing when the moving plate moves up and down, so that the moving plate can move up and down stably.
[0014] In one specific implementation, the water absorption mechanism includes a vertical plate connected to the bottom of a movable plate. A plurality of telescopic rods are connected to one side of the vertical plate, and a mounting plate is connected to the other end of the telescopic rods. An absorbent sponge is connected inside the mounting plate, and a first spring is sleeved on the outer surface of the telescopic rods.
[0015] In the above implementation process, by setting up the vertical plate, when the moving plate moves downward, it can drive the vertical plate downward, which in turn drives the water-absorbing sponge downward. The water-absorbing sponge wipes the fog on the glass surface in advance, and then the hot air blown out of the air outlet further removes the fog, thus increasing the defogging efficiency of the defogging mechanism.
[0016] In one specific implementation, the display cabinet body is internally connected to two sets of track plates. One side of each track plate is provided with a first track, a second track, a third track, a fourth track, and a fifth track. One end of the first track is connected to the second track, the other end of the second track is connected to the third track, the other end of the third track is connected to the fourth track, the other end of the fourth track is connected to the fifth track, and the other end of the fifth track is connected to the other end of the first track.
[0017] In the above implementation process, by setting the first track, second track, third track, fourth track and fifth track, the water-absorbing sponge can contact the glass surface when the moving plate moves downward. When it moves upward, since the air outlet moves in front of the water-absorbing sponge, the water-absorbing sponge does not need to contact the glass again, thus preventing the secondary generation of fog.
[0018] In one specific implementation, both ends of the mounting plate are connected to protrusions, and one end of the protrusion slides inside the first track, second track, third track, fourth track and fifth track.
[0019] In the above implementation process, by setting the bumps, when the moving plate moves, the bumps first pass through the first track, then through the second track, the third track, the fourth track and the fifth track, and finally return to the first track.
[0020] In one specific implementation, the track slab has a cavity inside, and a rotating shaft is rotatably connected to the inner wall of the cavity. The other end of the rotating shaft passes through the track slab, and a limit member is connected to the outer surface of the rotating shaft.
[0021] In the above implementation process, by setting the limiting component, when the protrusion contacts the limiting component from the first track, the protrusion cannot enter the fifth track and can only enter the second track. When the protrusion is in the fifth track, the first spring is in the restoring state. When passing through the second track, the first spring is stretched. When passing through the third track, the first spring is always in the stretched state. After reaching the fourth track, the first spring releases its elastic potential energy, driving the protrusion into the fifth track. At this time, the control motor output shaft drives the moving plate to move upward, causing the protrusion to slide inside the fifth track. The protrusion will pass through the limiting component and enter the first track.
[0022] In one specific implementation, a rotating plate is connected to the outer surface of the rotating shaft, a torsion spring is connected to one side of the rotating plate, and the other end of the torsion spring is connected to the interior of the cavity.
[0023] In the above implementation process, by setting the torsion spring, when the protrusion enters the first track from the fifth track, it can push the limiting member, drive the limiting member to rotate, drive the rotating plate to rotate, and make the limiting member rotate into the inside of the second track. After the protrusion completely passes through the limiting member, the torsion spring releases elastic potential energy, drives the limiting member back into the inside of the fifth track, so that the protrusion can move into the inside of the second track next time.
[0024] Compared with the prior art, the beneficial effects of this application are as follows: By setting up a defogging mechanism and a water absorption mechanism, the output shaft of the motor can be controlled to rotate, driving the threaded rod to rotate inside the first housing, driving the threaded seat to move up and down inside the first housing, and driving the two sets of air outlets to move up and down. The hot air generated by the hot air blown out through the air outlets is blown onto the surface of the glass, performing overall defogging on the glass. When the moving plate moves down, it drives the mounting plate to move down, causing the protrusion to slide inside the first track. The protrusion slides into the second track, and when it passes through the second track, it stretches the first spring. At this time, one side of the water-absorbing sponge contacts the surface of the glass, wiping the fog on the glass surface in advance with the water-absorbing sponge. Then, the hot air blown out by the air outlet further defogging occurs, increasing the defogging efficiency of the defogging mechanism. When passing through the third track, the first spring is always in a stretched state. After reaching the fourth track, the first spring releases its elastic potential energy, driving the protrusion into the fourth track. In the fifth track, one side of the absorbent sponge cannot contact the glass surface. As it moves upward, the air outlet moves in front of the absorbent sponge, so the sponge no longer needs to contact the glass, preventing secondary fogging. At this point, the control motor output shaft drives the moving plate upward, causing the protrusion to slide inside the fifth track. When the protrusion enters the first track from the fifth track, it pushes the limiting member, causing the limiting member to rotate. This causes the rotating plate to rotate, allowing the limiting member to rotate into the second track. After the protrusion has completely passed through the limiting member, the torsion spring releases its elastic potential energy, causing the limiting member to return to the inside of the fifth track, allowing the protrusion to move into the second track next time. This solves the problem that the resistance wire or heating film needs to slowly heat the glass, resulting in low defogging efficiency. To improve defogging efficiency, the resistance wire or heating film needs to be kept in working condition for continuous defogging of the glass, resulting in high energy consumption due to the long-term operation of the electric heating device.

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0029] Please see Figure 1 and Figure 2 This application provides a moisture-proof and dehumidifying display cabinet with automatic defogging function, including the display cabinet body 1.
[0030] Please see Figure 1 and Figure 2 The display case body 1 has a glass 4 embedded on one side. The display case body 1 is equipped with a defogging mechanism 2 for defogging the glass 4 and a water absorption mechanism 3 for absorbing the fog on the surface of the glass 4. The display case body 1 is also equipped with a humidity sensor. When fog is generated on the glass 4, the humidity sensor sends a signal to control the motor 205 and the hot air blower 201 to work. The humidity sensor is existing technology and will not be described in detail here.
[0031] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 The defogging mechanism 2 includes a hot air blower 201, which is connected inside the display case body 1. Both output ends of the hot air blower 201 are connected to air outlets 202, and the input end of the hot air blower 201 is connected to the outside of the display case. It can heat the air outside the display case and blow the hot air out through the air outlets 202 to defog the glass 4. The output end of the hot air blower 201 is connected to the air outlets 202 through a pipe. The pipe is long enough so that the air outlets 202 can move up and down inside the display case body 1.
[0032] In the specific setup, the display cabinet body 1 is internally connected to a first housing 203, and a motor 205 is connected to the top of the display cabinet body 1. The output shaft of the motor 205 passes through the first housing 203 and is connected to a screw 206. The other end of the screw 206 is rotatably connected to the inside of the first housing 203. Thus, by setting up the motor 205, the output shaft of the motor 205 can be controlled to rotate, thereby driving the screw rod to rotate inside the first housing 203.
[0033] In a specific configuration, the outer surface of the screw 206 is threadedly connected to a threaded seat 207, which is slidably connected inside the first housing 203. The screw 206 is configured such that when it rotates, the threaded seat 207 moves up and down inside the first housing 203.
[0034] In the specific setup, a movable plate 204 is connected to one side of the threaded seat 207. The movable plate 204 is connected to the bottom of the two sets of air outlets 202. The threaded seat 207 can move the movable plate 204 up and down when it moves, thereby moving the two sets of air outlets 202 up and down. The hot air blown out of the air outlets 202 can then be used to defog the glass 4 as a whole.
[0035] In the specific configuration, the display cabinet body 1 is internally connected to a second housing 208, and the second housing 208 is internally connected to a vertical rod 209. The outer surface of the vertical rod 209 is slidably connected to a sliding member 2010, which is connected to one side of the movable plate 204. The vertical rod 209 enables the sliding member 2010 to move up and down inside the second housing 208 when the movable plate 204 moves up and down, thus enabling the movable plate 204 to move up and down stably.
[0036] In a specific configuration, the water absorption mechanism 3 includes a vertical plate 302 connected to the bottom of the movable plate 204. One side of the vertical plate 302 is connected to multiple sets of telescopic rods 306, and the other end of the telescopic rods 306 is connected to a mounting plate 303. The interior of the mounting plate 303 is connected to a water-absorbing sponge 304, and the outer surface of the telescopic rods 306 is fitted with a first spring 307. The vertical plate 302 can be moved downwards when the movable plate 204 moves downwards, thereby moving the water-absorbing sponge 304 downwards. The water-absorbing sponge 304 can wipe the fog off the surface of the glass 4 in advance, and then the hot air blown out by the air outlet 202 can further defog the glass, thus increasing the defogging efficiency of the defogging mechanism 2.
[0037] In its specific configuration, the display cabinet body 1 is internally connected to two sets of track plates 301. One side of each track plate 301 has a first track 308, a second track 309, a third track 3010, a fourth track 3011, and a fifth track 3012. One end of the first track 308 is connected to the second track 309, the other end of the second track 309 is connected to the third track 3010, the other end of the third track 3010 is connected to the fourth track 3011, and the other end of the fourth track 3011 is connected to the fifth track 3012. The fifth track 3012 is connected to the other end of the first track 308. The arrangement of the first track 308, the second track 309, the third track 3010, the fourth track 3011 and the fifth track 3012 allows the water-absorbing sponge 304 to contact the surface of the glass 4 when the moving plate 204 moves downward. When it moves upward, since the air outlet 202 moves in front of the water-absorbing sponge 304, the water-absorbing sponge 304 does not need to contact the glass 4 again, thus preventing the secondary generation of fog.
[0038] In the specific configuration, both ends of the mounting plate 303 are connected to protrusions 305. One end of the protrusion 305 slides inside the first track 308, the second track 309, the third track 3010, the fourth track 3011, and the fifth track 3012. With the configuration of the protrusion 305, when the moving plate 204 moves, the protrusion 305 first passes through the first track 308, then through the second track 309, the third track 3010, the fourth track 3011, and the fifth track 3012, and finally returns to the first track 308.
[0039] In a specific configuration, a cavity 3016 is formed inside the track plate 301. A rotating shaft 3013 is rotatably connected to the inner wall of the cavity 3016. The other end of the rotating shaft 3013 passes through the track plate 301. A limiting member 3014 is connected to the outer surface of the rotating shaft 3013. Through the setting of the limiting member 3014, when the protrusion 305 contacts the limiting member 3014 from the first track 308, the protrusion 305 cannot enter the fifth track 3012 and can only enter the second track 309. When the protrusion 305 is on the fifth track 3012, the first spring 3... When 07 is in the restored state, the first spring 307 is stretched when passing through the second track 309. When passing through the third track 3010, the first spring 307 is always in a stretched state. After reaching the fourth track 3011, the first spring 307 releases its elastic potential energy, which drives the protrusion 305 into the fifth track 3012. At this time, the output shaft of the control motor 205 reverses, which drives the moving plate 204 to move upward, and drives the protrusion 305 to slide inside the fifth track 3012. The protrusion 305 will pass through the limiting member 3014 and enter the first track 308.
[0040] In a specific configuration, a rotating plate 3017 is connected to the outer surface of the rotating shaft 3013. A torsion spring 3015 is connected to one side of the rotating plate 3017, and the other end of the torsion spring 3015 is connected to the interior of the cavity 3016. The torsion spring 3015 allows the protrusion 305 to push the limiting member 3014 when it enters the first track 308 from the fifth track 3012, causing the limiting member 3014 to rotate and the rotating plate 3017 to rotate. This allows the limiting member 3014 to rotate into the interior of the second track 309. After the protrusion 305 has completely passed through the limiting member 3014, the torsion spring 3015 releases its elastic potential energy, causing the limiting member 3014 to return to the interior of the fifth track 3012, so that the protrusion 305 can move into the interior of the second track 309 next time.
[0041] The working principle of this dehumidifying and moisture-proof display cabinet with automatic defogging function is as follows: When using the dehumidifying and moisture-proof display cabinet with automatic defogging function, the output shaft of the motor 205 is rotated, which drives the threaded rod to rotate inside the first housing 203, causing the threaded seat 207 to move up and down inside the first housing 203, and causing the two sets of air outlets 202 to move up and down. The hot air generated by the hot air blower 201 is blown out to the surface of the glass 4 through the air outlets 202, and the glass 4 is defogged as a whole. When the moving plate 204 moves down, it drives the mounting plate 303 to move down, and drives the protrusion 305 on the first track. The protrusion 305 slides into the interior of the second track 309 as it passes through the second track 309. While passing through the second track 309, it stretches the first spring 307. At this time, one side of the absorbent sponge 304 contacts the surface of the glass 4, allowing the absorbent sponge 304 to wipe away the fog on the surface of the glass 4 beforehand. Then, the hot air blown out by the air outlet 202 further defogging the glass, increasing the defogging efficiency of the defogging mechanism 2. When passing through the third track 3010, the first spring 307 remains stretched. After reaching the fourth track 3011, the first spring 307 releases its elastic potential energy, causing the protrusion 305 to enter the fourth track 3011. In the fifth track 3012, one side of the absorbent sponge 304 cannot contact the surface of the glass 4. As it moves upwards, because the air outlet 202 moves in front of the absorbent sponge 304, the absorbent sponge 304 no longer needs to contact the glass 4, preventing secondary fogging. At this time, the output shaft of the control motor 205 reverses, driving the moving plate 204 upwards, causing the protrusion 305 to slide inside the fifth track 3012. When the protrusion 305 enters the first track 308 from the fifth track 3012, it pushes the limiting member 3014, causing the limiting member 3014 to rotate, and driving the rotating plate 301... 7. Rotate the limiting member 3014 to the inside of the second track 309. After the protrusion 305 completely passes through the limiting member 3014, the torsion spring 3015 releases its elastic potential energy, driving the limiting member 3014 back to the inside of the fifth track 3012, so that the protrusion 305 can move into the inside of the second track 309 next time. This solves the problem that the defogging efficiency is low because the resistance wire or heating film needs to slowly heat the glass 4. In order to improve the defogging efficiency, the resistance wire or heating film needs to be kept in working state at all times to continuously defog the glass 4, which consumes a lot of energy due to the long-term operation of the electric heating device.
[0042] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
