Description

Technical Field

[0001] The present invention relates to the technical field of lighting devices, and particularly to a portable outdoor LED lighting fixture. Background Art

[0002] LED lighting fixtures are outdoor lighting devices that use light-emitting diodes (LEDs) as light sources, and have many advantages such as energy saving, environmental protection, and long lifespan. Therefore, they are widely used in outdoor lighting scenarios. Portable LED lighting fixtures are usually suitable for scenarios where the position needs to be frequently moved, such as camping LED lighting fixtures, and have characteristics such as small size and easy to carry.

[0003] In the prior art, due to the large temperature difference between night and day, the air pressure difference inside and outside the lighting fixture increases, so humid air is inhaled into the lighting fixture through the air vent valve or micropores, forming water mist inside the glass cover and accumulating water after condensation. This will not only affect the lighting effect of the lighting fixture, but may also cause safety problems such as electric leakage. There is an existing Chinese invention patent: 202411583521.4, a self-balancing waterproof structure for an ultra-thin LED outdoor floodlight, which heats the air inside the glass cover to promote the evaporation of water inside the glass cover into water vapor, and separates the air with water vapor through a waterproof breathable membrane, thereby achieving the effect of removing moisture inside the glass cover of the lighting fixture. However, it heats the water droplets with hot air, and the evaporation of water droplets requires a high amount of heat, but the LED lights inside the glass cover will be in a high-temperature state, and the LED lights will be damaged in a high-temperature environment, which will affect the service life of the LED lights.

[0015] Compared with the prior art, the present application includes at least one of the following beneficial technical effects: 1. By setting up a dehumidification component, the humid air inside the glass cover can be drawn into the long tube by a fan, and the moisture in the humid air can be adsorbed by the silica gel adsorption particles arranged inside the dehumidification cylinder. The air flow will drive the agitation structure to operate and make the two agitation plates rotate, which can fully turn over the silica gel adsorption particles in the placement cylinder, facilitating the improvement of the adsorption efficiency of humid air. The treated dry air will be re-injected into the inner wall of the lamp glass cover through the top of the long tube, thereby reducing the humidity inside the glass cover and preventing fogging and water accumulation caused by moisture, solving the problem that water mist is easily formed by the humid air inside the glass cover of the lighting fixture.

[0016] 2. By setting up a drying mechanism, the waste heat generated during the operation of the lamp body can be used to preheat the silica gel adsorption particles in the placement cylinder, which is beneficial to the utilization of energy conservation and at the same time prevents the silica gel adsorption particles from becoming shriveled due to excessive heating.

Detailed implementation manners

[0021] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] As Figures 1 - 14 shown, a portable outdoor LED lighting fixture proposed by the present invention includes a fixture body 1. A support frame 2 is rotatably connected to the side of the fixture body 1. A handle 4 is rotatably connected to the top of the fixture body 1. A heat dissipation fin 5 is fixedly connected to one side of the fixture body 1. The fixture also includes a dehumidification component for removing humid air inside the fixture body 1. The dehumidification component is arranged outside the fixture body 1 to dehumidify the inside of the fixture body 1 outside, effectively preventing heat from entering the inside of the fixture body 1.

[0023] In this embodiment, the dehumidification component includes a long tube 6 installed on the fixture body 1, and a negative pressure mechanism, a drying mechanism, and a collection mechanism sequentially arranged from top to bottom on the long tube 6; Among them, the drying mechanism includes a dehumidification cylinder 28 installed on the long tube 6. A placing cylinder 13 is installed inside the dehumidification cylinder 28. Silica gel particles are filled in the placing cylinder 13. A heating structure for heating the silica gel particles is installed on the long tube 6. The drying mechanism also includes a stirring structure installed inside the placing cylinder 13 and used for stirring the silica gel particles, so that the silica gel particles can fully adsorb water vapor.

[0024] It should be noted that to solve the problem that water mist is easily formed by humid air inside the glass cover of outdoor lighting fixtures, when using the LED lighting fixture outdoors, the handle 4 can be pulled to lift the fixture body 1 and move the fixture body 1 to a suitable placement position. Subsequently, the irradiation angle of the fixture body 1 can be adjusted according to requirements. When the fixture body 1 is operating, it is beneficial to dissipate heat from the back of the fixture body 1 through multiple groups of heat dissipation fins 5. When it is necessary to dehumidify the inside of the glass cover of the fixture body 1, the negative pressure mechanism can be used to transfer the humid air inside the fixture body 1 into the inside of the long tube 6. The silica gel particle dehumidifier arranged in the placing cylinder 13 can adsorb the passing humid air to reduce the moisture in the air. By setting the stirring structure, when adsorbing the humid air, the silica gel adsorption particles in the placing cylinder 13 can be stirred, which is beneficial to enabling the silica gel adsorbent to more fully absorb the moisture in the air. By setting the heating structure, the placing cylinder 13 can be heated after the adsorption of the humid air is completed, so that the temperature of the silica gel particles in the placing cylinder 13 rises, and after the temperature rises, the moisture in the silica gel particles will be removed, which is beneficial to the multiple use of the silica gel adsorption particles in the placing cylinder 13. The removed moisture will be collected by the collection mechanism.

[0025] As Figures 3 - 6The negative pressure mechanism is used to guide the airflow inside the lamp body 1 to enter the long tube 6 and flow back to the inside of the lamp body 1; the negative pressure mechanism includes a wind tube 7, which is fixedly connected to the top of the long tube 6, and a fan 8 is fixedly connected inside the wind tube 7. A first one-way valve 11 is fixedly connected to the inner wall of the top of the long tube 6, and a second one-way valve 12 is fixedly connected to the inner wall of the bottom of the long tube 6.

[0026] When the air between the reflector and the glass cover needs to be dehumidified, the operation of the lamp body 1 is stopped first, and then the fan 8 is started. Since the fan 8 is arranged at the top of the long tube 6, it can generate negative pressure inside the long tube 6 when the fan 8 is started, and the air between the reflector and the glass cover is sucked into the bottom of the long tube 6. When air or accumulated water enters the bottom of the long tube 6, the second one-way valve 12 can be pushed open to release the seal between the bottom of the long tube 6 and the inside of the lamp body 1, so that air can enter the inside of the long tube 6 from below. If there is water between the reflector and the glass cover, the second one-way valve 12 can be pushed open to release the seal between the bottom of the long tube 6 and the inside of the lamp body 1, so that air can enter the inside of the long tube 6 from below. , the accumulated water can flow into the collecting mechanism through the bottom of the long tube 6, which is convenient for collecting the accumulated water. Under the action of the suction force generated by the fan 8, the humid air can enter the dehumidification cylinder 28 and pass through the placement cylinder 13. The silica gel adsorption particles in the placement cylinder 13 can absorb moisture. The dry air after adsorption will continue to flow to the top of the long tube 6 and push open the first one-way valve 11, so that the dry air re-enters between the reflector and the glass cover, thereby reducing the humidity of the air between the reflector and the glass cover and preventing fogging and water accumulation caused by humidity.

[0027] like Figure 3 and Figure 7 The stirring structure includes a round rod 14, which is rotatably connected to the inner wall of the dehumidification cylinder 28, and a plurality of groups of arc blades 15 are fixedly connected to the outer wall of the round rod 14, and the arc blades 15 are arranged at the top of the inner wall of the dehumidification cylinder 28. A guide block 56 is fixedly connected to the inner wall of the dehumidification cylinder 28, and a first bevel gear 16 is fixedly connected to the outer wall of the round rod 14. A second bevel gear 17 is meshed at the bottom of the first bevel gear 16, and a long rod 18 is fixedly connected to the bottom of the second bevel gear 17. The long rod 18 is arranged at the center of the plurality of groups of arc blades 15, and a third bevel gear 19 is fixedly connected to the outer wall of the long rod 18. A fourth bevel gear 20 is meshed at one side of the third bevel gear 19, and a stirring plate 21 is fixedly connected to one side of the fourth bevel gear 20, and a circular hole is opened on one side of the stirring plate 21, and a protective shell is provided at the meshing point of the third bevel gear 19 and the fourth bevel gear 20.

[0028] When the air after adsorption flows upward in the dehumidifying cylinder 28, the air can be guided to flow to one side through the guiding block 56. When the air enters the connection between the top of the dehumidifying cylinder 28 and the long pipe 6, the flow of the air can drive a plurality of arc-shaped blades 15 to rotate. Due to the existence of the guiding block 56, the area of the connection between the top of the dehumidifying cylinder 28 and the long pipe 6 will be reduced, so that the flow rate of the steam can be increased through the venturi effect, which can prompt the steam to push the arc-shaped blades 15 to rotate, and at the same time keep the arc-shaped blades 15 rotating in one direction. When the arc-shaped blades 15 rotate, they will drive the round rod 14 and the first bevel gear 16 to rotate. When the first bevel gear 16 rotates, it will drive the second bevel gear 17 and the long rod 18 at the bottom to rotate together. Since there are openings at the centers of the plurality of arc-shaped blades 15, the rotation of the arc-shaped blades 15 will not affect the rotation of the long rod 18. The third bevel gear 19 provided on the outer wall of the long rod 18 will rotate together with the long rod 18. When the third bevel gear 19 rotates, it will drive the fourth bevel gears 20 and the stirring plates 21 on both sides to rotate together. The protective shell can protect the meshing between the third bevel gear 19 and the fourth bevel gear 20. When the two stirring plates 21 rotate in opposite directions at the same time, the silica gel adsorption particles in the placing cylinder 13 can be fully turned over, which is beneficial to the uniform adsorption of moisture on the surface of the silica gel adsorption particles, thereby improving the adsorption efficiency of the humid air. At the same time, the round holes provided on the stirring plates 21 can also allow some silica gel particles to pass through the round holes during their turning, which can reduce the resistance of the stirring plates 21 to turn over.

[0029] Such as Figure 3 , Figure 10 and Figure 12 , the heating structure includes a contact head 22, the contact head 22 is fixedly connected to the outer wall of the placing cylinder 13, a plurality of groups of the contact heads 22 are provided and are circumferentially distributed on the outer wall of the placing cylinder 13, one end of the contact head 22 penetrates through the dehumidifying cylinder 28, a conduction ring 25 is fixedly connected to the outer wall of the contact head 22, a heating ring 23 is fixedly connected to the outer wall of the conduction ring 25, a heater 24 is fixedly connected to the top of the heating ring 23, a cross bar 26 is fixedly connected to the outer wall of the conduction ring 25, the cross bar 26 is fixedly connected to the center of a plurality of heat dissipation fins 5, a fitting piece 27 is fixedly connected to one side of the cross bar 26, the fitting piece 27 is fixedly connected to one side of the lamp body 1, and the contact head 22, the conduction ring 25, the cross bar 26, the fitting piece 27 and the placing cylinder 13 are all made of heat-conducting materials.

[0030] After the air adsorption is completed, the operation of the blower 8 can be stopped. The first one-way valve 11 and the second one-way valve 12 can temporarily seal the top and bottom of the long tube 6. The multi-group of heat dissipation fins 5 can be connected in series through the cross bar 26, so that the heat on the heat dissipation fins 5 is transferred to the cross bar 26. At the same time, the fitting piece 27 is also beneficial to transfer the heat on one side of the lamp body 1, and transfer the heat to the conduction ring 25 through the cross bar 26. It can accelerate the heat dissipation of the lamp body 1 while using the waste heat generated by the heat dissipation fins 5 and one side of the lamp body 1 to preheat the conduction ring 25, which is beneficial to the utilization of energy and prevents the silica gel adsorption particles from drying out due to too fast heating. Then, start the heater 24 to raise the temperature of the heating ring 23 and transfer the temperature to the conduction ring 25. Since the transfer ring is connected to the placement cylinder 13 through multiple contact heads 22, and the transfer ring, the contact heads 22 and the placement cylinder 13 are all made of heat-conducting materials, the temperature generated by the heating ring 23 can be transferred to the inside of the placement cylinder 13 through the transfer ring and the contact heads 22, which is convenient for heating the silica gel adsorption particles in the placement cylinder 13. After the silica gel adsorption particles are heated, the adsorbed water will be separated out, and the dehydrated silica gel adsorption particles can play an adsorption effect again after cooling.

[0031] Such as Figure 3 And Figure 8 As shown in and, the drying mechanism further includes a processing structure and a closing structure. The processing structure includes a side tube 29, the side tube 29 is fixedly connected to one side of the long tube 6, the bottom of the side tube 29 is fixedly connected to a connecting tube 30, the connecting tube 30 is fixedly connected to one side of the long tube 6, a third one-way valve 40 is arranged at the bottom of the connecting tube 30, a threaded tube 37 is fixedly connected to the outer wall of the side tube 29, a condenser 38 is fixedly connected to the bottom of the threaded tube 37, and a support plate 39 is fixedly connected to the bottom of the condenser 38. The support plate 39 is fixedly connected to one side of the lamp body 1.

[0032] When dehydrating the silica gel adsorbent, the long tube 6 at the top of the dehumidifying cylinder 28 can be sealed by a closing structure first, and at the same time, one side of the side tube 29 is opened. After the silica gel adsorbent is heated, the moisture in the silica gel adsorbent will be converted into water vapor and flow upward. When the water vapor flows upward, it will be guided by the guiding block 56 again and flow into the long tube 6 on one side. During the flowing process, it will drive the arc-shaped blade 15 to rotate slowly, and drive the stirring plate 21 to turn over through structures such as the round rod 14, the first bevel gear 16, and the second bevel gear 17. When heating the silica gel adsorption particles, the silica gel adsorption particles can be heated evenly by the turning of the stirring plate 21. Since the closing structure seals the inside of the long tube 6, the water vapor entering the long tube 6 will flow into the inside of the side tube 29. By starting the condenser 38 to inject the refrigerant into the threaded tube 37, the temperature in the threaded tube 37 can be lower than the normal temperature. Since the threaded tube 37 is arranged on the outer wall of the side tube 29, the temperature inside the side tube 29 can be reduced. When the water vapor enters the low-temperature side tube 29, it will condense in the side tube 29 and flow downward by gravity into the connecting tube 30. After the water converges, it will push open the third one-way valve 40, so that the condensed water flows into the inner wall of the long tube 6 and flows downward by gravity into the inclined tube 9 and the storage tank 10.

[0033] As Figure 3 and Figure 11 The closing structure includes a short rod 31, the short rod 31 is rotatably connected to the inner wall of the long tube 6, a plug 32 is fixedly connected to one side of the short rod 31, a fitting sleeve 33 is fixedly connected to the inner wall of the long tube 6, there are two groups of the fitting sleeves 33, and the other group of the fitting sleeves 33 is fixedly connected to the inner wall of the side tube 29. The plug 32 fits against one side of a group of fitting sleeves 33. One side of the short rod 31 extends out of the long tube 6, a square plate 34 is fixedly connected to one end of the short rod 31, a first magnet 35 is fixedly connected to one side of the side tube 29, the square plate 34 is made of iron, the square plate 34 is arranged at the top of the first magnet 35, and a second magnet 36 is fixedly connected to one side of the long tube 6.

[0034] When it is necessary to seal the long tube 6 above the dehumidifying cylinder 28, the square plate 34 can be pushed to make the square plate 34 turn upward and release the fixation with the first magnet 35. When the square plate 34 turns, it will drive the short rod 31 and the plug 32 to turn together, so that the plug 32 gradually turns upward from one side of the side tube 29. Until the square plate 34 rotates 90 degrees, the other side of the square plate 34 will be adsorbed by the second magnet 36, and the positions of the square plate 34, the short rod 31 and the plug 32 will be fixed. At this time, the plug 32 abuts against a group of fitting sleeves 33 inside the long tube 6, the long tube 6 can be sealed, and one side of the side tube 29 can be opened. The sealing performance of the plug 32 can be improved through the fitting sleeve 33.

[0035] As Figure 7, the bottom of the long rod 18 extends out of the placement cylinder 13. A long strip blade 41 is fixedly connected to the bottom of the long rod 18. A circular ring 42 is fixedly connected to the outer wall of the long strip blade 41. A throwing needle 43 is fixedly connected to the bottom of the circular ring 42. The bottom of the throwing needle 43 inclines towards the center. The bottom of the throwing needle 43 is arranged at the connection of the long tube 6 and the connecting tube 30.

[0036] When dehumidifying the humid air inside the lamp body 1, since the humid air will pass through the long strip blade 41, it will drive the long strip blade 41 to rotate. The rotation generated by the long strip blade 41 is in the same direction as the rotation direction of the long rod 18, which can improve the driving force of the rotation of the long rod 18. The circular ring 42 and the two groups of throwing needles 43 will also rotate along with the long strip blade 41. Since the throwing needle 43 is arranged at the connection of the long tube 6 and the connecting tube 30, and there is a gap between the bottom of the throwing needle 43 and the inner wall of the long tube 6, the throwing needle 43 will contact the residual water droplets on the inner wall of the long tube 6 when rotating, and will throw the water droplets downward after contacting the water droplets, which can prompt the residual water droplets at the connection of the connecting tube 30 and the long tube 6 to fall. At the same time, the bottom of the throwing needle 43 inclines towards the center, so it is convenient to make the water droplets be thrown downward towards the center under the drive of gravity and centrifugal force, which is more conducive to the water droplets falling downward and preventing the remaining water droplets from existing at the bottom of the placement cylinder 13 and affecting the adsorption effect of the silica gel adsorption particles on the humid air.

[0037] Such as Figure 5 and Figure 13 , the collecting mechanism is used to collect the condensed water formed by the evaporated water vapor of the heated silica gel particles. The collecting mechanism includes an inclined tube 9. The inclined tube 9 is fixedly connected to the bottom of the long tube 6. A storage tank 10 is fixedly connected to the bottom of the inclined tube 9. A collecting box 44 is fixedly connected to the bottom of the storage tank 10. The top end of the collecting box 44 is rotationally connected to a sealing plate 45 through a rotating shaft. A hydraulic rod 46 is fixedly connected to one side of the collecting box 44. The output end of the hydraulic rod 46 is fixedly connected to a connecting plate 47. A push rod 48 is fixedly connected to the top end of the connecting plate 47. One end of the push rod 48 extends into the inner wall of the collecting box 44. A sealing sleeve is arranged at the connection of the push rod 48 and the collecting box 44. A push plate 49 is fixedly connected to one end of the push rod 48. The shape of the push plate 49 is T-shaped. A transmission tube 50 is fixedly connected to one end of the collecting box 44. The transmission tube 50 extends into the inner wall of the lamp body 1. A sleeve frame 51 is fixedly connected to the inner wall of the lamp body 1. The transmission tube 50 is fixedly connected to the bottom of the sleeve frame 51. An injection tube 52 is fixedly connected to the top end of the collecting box 44.

[0038] Since the bottom of the storage tank 10 is connected to the collection box 44, the water in the storage tank 10 will flow into the collection box 44. When the interior of the lamp body 1 needs to be cooled, the hydraulic rod 46 can be activated to drive the connecting plate 47 to move toward the side of the collection box 44 through the contraction of the hydraulic rod 46. When the connecting plate 47 moves, it will also drive the push rod 48 and the push plate 49 to move together. A sealing pad is provided on the side of the push plate 49 to prevent the accumulated water from flowing to the other side of the collection box 44 during movement. The push plate 49 is in a T-shape, so when the push plate 49 moves, the push plate 49 is in a T-shape. When the lamp body 1 is moving, the sealing plate 45 can be pushed upward to seal the connection between the storage tank 10 and the collection box 44 to prevent water from being squeezed and flowing into the storage tank 10. After being squeezed, the water will move into the transmission tube 50 and flow into the inner wall of the sleeve frame 51 through the transmission tube 50. Since the sleeve frame 51 is made of heat-conducting material and is arranged on the inner wall of the lamp body 1, the water in the sleeve frame 51 can be used to cool the interior of the lamp body 1. When there is insufficient water but cooling is still required, water can be added to the collection box 44 through the injection tube 52.

[0039] like Figure 12 A heat-conducting rod 53 is fixedly connected to the bottom of the cross bar 26 , a storage box 54 is fixedly connected to one side of the lamp body 1 , the inner wall of the storage box 54 is provided with plant essential oil, and the bottom of the heat-conducting rod 53 is provided on the inner wall of the storage box 54 .

[0040] When the cross bar 26 absorbs the heat of multiple groups of heat sinks, the heat-conducting rod 53 below can be heated. When the heat-conducting rod 53 is heated, it will transfer the temperature to the storage box 54, so that the plant essential oil in the storage box 54 will be heated. The heated plant essential oil will increase the volatilization efficiency, so that the plant essential oil can be volatilized into the air around the lamp body 1 to drive away the surrounding flying insects and prevent more flying insects from gathering around the lamp body 1 due to phototaxis.

[0041] like Figure 6 A shunt pipe 55 is fixedly connected to one side of the top of the long tube 6. Four groups of shunt pipes 55 are arranged and are symmetrically distributed at the bottom and top of the long tube 6. A support leg 3 is fixedly connected to the bottom of the support frame 2.

[0042] By arranging two groups of manifolds 55 at the top and bottom of the long tube 6 respectively, when the humid air is sucked into the bottom of the long tube 6, the range of the humid air sucked in can be increased through the two groups of manifolds 55, and when the dry air is transmitted from the top of the long tube 6 into the space between the reflector and the glass cover, the dry air can be evenly injected through the two groups of manifolds 55 above.

[0043] Working principle: In order to solve the problem that humid air inside the glass cover of outdoor lighting fixtures is prone to form water mist, when using LED lighting fixtures outdoors, the handle 4 can be pulled to lift the lamp body 1, and the lamp body 1 can be moved to a suitable position, and then the irradiation angle of the lamp body 1 can be adjusted according to needs. When the lamp body 1 is running, it can be beneficial to dissipate heat for the back of the lamp body 1 through multiple groups of heat dissipation fins 5. When it is necessary to dehumidify the air between the reflector and the glass cover, first stop the operation of the lamp body 1, and then start the fan 8. Since the fan 8 is set at the top of the long tube 6, when the fan 8 is started, it can generate negative pressure inside the long tube 6, and suck the air between the reflector and the glass cover into the bottom of the long tube 6, and when humid air or accumulated water enters the long tube 6, the second one-way valve 12 can be pushed open to release the seal between the bottom of the long tube 6 and the inside of the lamp body 1, so that air can enter the inside of the long tube 6 from below. If there is water accumulation between the reflector and the glass cover, the accumulated water can flow into the inclined tube 9 and the storage tank 10 through the bottom of the long tube 6, so as to collect the accumulated water. Under the suction force generated by the fan 8, the humid air can enter the dehumidification cylinder 28 and pass through the placement cylinder 13. The silica gel adsorption particles in the placement cylinder 13 can absorb the moisture. After adsorption, the dry air will continue to flow to the top of the long tube 6 and push open the first one-way valve 11, so that the dry air can re-enter between the reflector and the glass cover, thereby reducing the humidity of the air between the reflector and the glass cover, and preventing fogging and water accumulation caused by humidity. When the adsorbed air flows upward in the dehumidifying cylinder 28, the air can be guided to flow to one side through the guiding block 56. When the air enters the connection between the top of the dehumidifying cylinder 28 and the long pipe 6, the flow of the air can drive a plurality of arc-shaped blades 15 to rotate. Due to the existence of the guiding block 56, the area of the connection between the top of the dehumidifying cylinder 28 and the long pipe 6 will be reduced, so that the flow rate of the steam can be increased through the venturi effect, which can prompt the steam to push the arc-shaped blades 15 to rotate, and at the same time keep the arc-shaped blades 15 rotating in one direction. When the arc-shaped blades 15 rotate, they will drive the round rod 14 and the first bevel gear 16 to rotate. When the first bevel gear 16 rotates, it will drive the second bevel gear 17 and the long rod 18 at the bottom to rotate together. Since there are openings at the centers of the plurality of arc-shaped blades 15, the rotation of the arc-shaped blades 15 will not affect the rotation of the long rod 18. The third bevel gear 19 provided on the outer wall of the long rod 18 will rotate together with the long rod 18. When the third bevel gear 19 rotates, it will drive the fourth bevel gears 20 and the stirring plates 21 on both sides to rotate together. When the two stirring plates 21 rotate in opposite directions at the same time, the silica gel adsorption particles in the placing cylinder 13 can be fully turned over, which is beneficial to the uniform adsorption of the moisture in the passing air on the surface of the silica gel adsorption particles, thereby improving the adsorption efficiency of the humid air. At the same time, the circular holes provided on the stirring plates 21 can also allow some silica gel particles to pass through the circular holes during their turning, which can reduce the resistance of the stirring plates 21 to turn. Since the humid air will pass through the long strip blades 41 after entering the dehumidifying cylinder 28, the long strip blades 41 will be driven to rotate, and the rotation generated by the long strip blades 41 is in the same direction as the rotation direction of the long rod 18, which can improve the driving force of the long rod 18 to rotate. After the air adsorption is completed, the operation of the fan 8 can be stopped, and the first one-way valve 11 and the second one-way valve 12 can temporarily seal the top and the bottom of the long pipe 6; By pushing the square plate 34 to turn upwards, the fixation with the first magnet 35 can be released. When the square plate 34 turns, it will drive the short rod 31 and the plug 32 to rotate together, causing the plug 32 to gradually turn upwards from one side of the side pipe 29 until the square plate 34 rotates 90 degrees. Then, the other side of the square plate 34 will be adsorbed by the second magnet 36, and the positions of the square plate 34, the short rod 31, and the plug 32 will be fixed. At this time, the plug 32 abuts against a set of fitting sleeves 33 inside the long pipe 6, which can seal the long pipe 6 and open one side of the side pipe 29. The cross bar 26 can connect multiple sets of heat dissipation fins 5 in series, enabling the heat on the heat dissipation fins 5 to be transferred to the cross bar 26. At the same time, the fitting piece 27 is also conducive to transferring the heat on one side of the lamp body 1. The cross bar 26 can transfer the heat into the heat conduction rod 53 and heat the essential oil for plants in the storage box 54, thereby achieving the effect of repelling insects. At the same time, the cross bar 26 will transfer the heat to the conduction ring 25, which can not only accelerate the heat dissipation of the lamp body 1 but also preheat the conduction ring 25 using the waste heat generated by the heat dissipation fins 5 and one side of the lamp body 1, which is beneficial to saving energy and preventing the silica gel adsorption particles from drying out due to excessive heating. Subsequently, start the heater 24 to raise the temperature of the heating ring 23 and transfer the temperature to the conduction ring 25. Since the transfer ring is connected to the placement cylinder 13 through multiple contact heads 22, and the transfer ring, the contact heads 22, and the placement cylinder 13 are all made of heat-conducting materials, the temperature generated by the heating ring 23 can be transferred to the inside of the placement cylinder 13 through the transfer ring and the contact heads 22, facilitating the heating of the silica gel adsorption particles inside the placement cylinder 13. After the silica gel adsorption particles are heated, the adsorbed water will turn into water vapor and escape. After dehydration, the silica gel adsorption particles can adsorb again after cooling, which is beneficial for the silica gel adsorption particles inside the placement cylinder 13 to be used multiple times. When the water vapor flows upwards, it will be guided by the guiding block 56 again and flow into the long pipe 6 on one side. During the flowing process, it will drive the arc-shaped blade 15 to rotate slowly, and drive the stirring plate 21 to turn through structures such as the round rod 14, the first bevel gear 16, and the second bevel gear 17. When heating the silica gel adsorption particles, the stirring plate 21 can be used to turn the silica gel adsorption particles to make them evenly heated. Since the plug 32 seals the inside of the long pipe 6, the water vapor will flow into the inside of the side pipe 29. By starting the condenser 38 to inject the refrigerant into the threaded pipe 37, the temperature of the threaded pipe 37 can be reduced. Since the threaded pipe 37 is arranged on the outer wall of the side pipe 29, the temperature inside the side pipe 29 can be reduced. When the water vapor enters the low-temperature side pipe 29, it will condense inside the side pipe 29 and flow downwards by gravity into the connecting pipe 30. After the water converges downwards, it will push open the third one-way valve 40, enabling the condensed water to flow into the inner wall of the long pipe 6 and then flow downwards by gravity into the inclined pipe 9 and the storage tank 10; During subsequent dehumidification operations, the circular ring 42 will rotate together with the long strip blades 41 and the long rod 18. When the circular ring 42 rotates, it will drive the two groups of throwing needles 43 to rotate together. When the throwing needles 43 rotate, they will contact the residual water droplets on the inner wall of the long tube 6 and throw the water droplets downward after contacting them, which can prompt the residual water droplets at the connection between the connecting pipe 30 and the long tube 6 to fall off. At the same time, the bottom of the throwing needle 43 inclines towards the center, so it is convenient to make the water droplets be thrown towards the center at the bottom under the drive of gravity and centrifugal force, which is more conducive to the water droplets falling downward into the storage tank 10, preventing the residual water droplets from existing at the bottom of the placing cylinder 13 and affecting the adsorption effect of the silica gel adsorption particles on the humid air. At the same time, when the steam drives the long rod 18 to rotate, it can also drive the throwing needles 43 to rotate to clean the residual water droplets, preventing the water droplets from aggregating under the placing cylinder 13 and wasting the adsorption effect of the silica gel. After drying the silica gel, when the subsequent lamp body 1 needs to dissipate heat during operation, the hydraulic rod 46 can contract to drive the connecting plate 47, the push rod 48 and the push plate 49 to move together. A sealing gasket is arranged on the side of the push plate 49 to prevent the accumulated water from flowing to the other side of the collection box 44 during movement. The shape of the push plate 49 is T-shaped, so when the push plate 49 moves, it can push the sealing plate 45 upward, thereby closing the connection between the storage tank 10 and the collection box 44 to prevent the water from being squeezed into the storage tank 10. And the water will move into the transmission pipe 50 after being squeezed and flow into the inner wall of the sleeve frame 51 through the transmission pipe 50. Since the sleeve frame 51 is arranged on the inner wall of the lamp body 1, the water in the sleeve frame 51 can be used to cool the inside of the lamp body 1. When the accumulated water is insufficient but still needs to be cooled, water can be added into the collection box 44 through the injection pipe 52 to facilitate continuous cooling of the inside of the lamp body 1.
