DETAILED DESCRIPTION

[0041] The technical solutions of the present application are further described below in combination with the drawings and specific embodiments.

[0042] As Figures 1-14 shown, the present application proposes a portable outdoor LED lighting lamp, which comprises a lamp body 1, the lamp body 1 is rotatably connected with a support frame 2 on the side, the lamp body 1 is rotatably connected with a handle 4 at the top end, and the lamp body 1 is fixedly connected with heat dissipation fins 5 on one side; the portable outdoor LED lighting lamp further comprises a dehumidification assembly for removing the humid air inside the lamp body 1, which is arranged outside the lamp body 1 to dehumidify the inside of the lamp body 1, effectively avoiding the heat from entering the inside of the lamp body 1.

[0043] In this embodiment, the dehumidification assembly comprises a long tube 6 installed on the lamp body 1, and a negative pressure mechanism, a drying mechanism and a collection mechanism are sequentially arranged on the long tube 6 from top to bottom;

[0044] The drying mechanism comprises a dehumidification cylinder 28 installed on the long tube 6, a placing cylinder 13 is installed in the dehumidification cylinder 28, silica gel particles are filled in the placing cylinder 13, and a heating structure for heating the silica gel particles is installed on the long tube 6; the drying mechanism further comprises a stirring structure installed in the placing cylinder 13 and used for stirring the silica gel particles, so that the silica gel particles can fully absorb water vapor.

[0045] It is worth mentioning that in order to solve the problem that the humid air inside the glass cover of the outdoor lighting lamp is easy to form water mist, when using the LED lighting lamp outdoors, the handle 4 can be pulled to lift the lamp body 1, and the lamp body 1 is moved to a suitable position, and then the illumination angle of the lamp body 1 can be adjusted according to the needs. When the lamp body 1 is running, it can be beneficial to dissipate heat from the back of the lamp body 1 through the plurality of heat dissipation fins 5. When it is necessary to dehumidify the inside of the glass cover of the lamp body 1, the humid air inside the lamp body 1 can be sent into the inside of the long tube 6 through the negative pressure mechanism. The silica gel particle desiccant arranged in the placement cylinder 13 can adsorb the humid air passing through to reduce the moisture in the air. By arranging the stirring structure, the silica gel adsorption particles in the placement cylinder 13 can be stirred when adsorbing the humid air, which is beneficial to make the silica gel adsorbent more fully absorb the moisture in the air. By arranging the heating structure, the placement cylinder 13 can be heated after the humid air adsorption is completed, so that the silica gel particles in the placement cylinder 13 are heated, and the moisture in the silica gel particles is released after heating, which is beneficial to the repeated use of the silica gel adsorption particles in the placement cylinder 13, and the released water is collected by the collecting mechanism.

[0046] As Figures 3-6 , the negative pressure mechanism is used to guide the airflow inside the lamp body 1 into the long tube 6 and backflow into the inside of the lamp body 1; the negative pressure mechanism comprises a wind cylinder 7, the wind cylinder 7 is fixedly connected at the top of the long tube 6, the wind fan 8 is fixedly connected in the inside of the wind cylinder 7, the inner wall of the top of the long tube 6 is fixedly connected with the first one-way valve 11, and the inner wall of the bottom of the long tube 6 is fixedly connected with the second one-way valve 12.

[0047] When it is necessary to dehumidify the air between the reflector and the glass cover, the operation of the lamp body 1 is stopped first, and then the wind fan 8 is started. Since the wind fan 8 is arranged at the top end of the long tube 6, the wind fan 8 can generate negative pressure in the inside of the long tube 6 when it is started, and the air between the reflector and the glass cover is sucked into the bottom of the long tube 6. When the air or water enters the bottom of the long tube 6, the second one-way valve 12 can be opened, the closure between the bottom of the long tube 6 and the inside of the lamp body 1 is released, the air enters the inside of the long tube 6 from below, if there is water between the reflector and the glass cover, the water can flow into the collecting mechanism through the bottom of the long tube 6, which is convenient for collecting the water. Under the action of the suction force of the wind fan 8, the humid air can enter the dehumidifying cylinder 28, and pass through the placement cylinder 13. The silica gel adsorption particles in the placement cylinder 13 can adsorb the moisture, and the dry air after adsorption can continue to flow upwards in the long tube 6, and open the first one-way valve 11, so that the dry air reenters between the reflector and the glass cover, thereby reducing the humidity of the air between the reflector and the glass cover, preventing fogging and water accumulation caused by humidity.

[0048] As Figure 3 andFigure 7 The stirring structure comprises a round rod 14 rotatably connected to the inner wall of the dehumidifying cylinder 28, a plurality of groups of arc-shaped blades 15 fixed to the outer wall of the round rod 14, the arc-shaped blades 15 being arranged at the top end of the inner wall of the dehumidifying cylinder 28, a guide block 56 fixed to the inner wall of the dehumidifying cylinder 28, a first bevel gear 16 fixed to the outer wall of the round rod 14, a second bevel gear 17 engaged with the bottom of the first bevel gear 16, a long rod 18 fixed to the bottom of the second bevel gear 17, the long rod 18 being arranged at the center of the plurality of groups of arc-shaped blades 15, a third bevel gear 19 fixed to the outer wall of the long rod 18, a fourth bevel gear 20 engaged with one side of the third bevel gear 19, a stirring plate 21 fixed to one side of the fourth bevel gear 20, a round hole being formed in one side of the stirring plate 21, and a protective shell being arranged at the engagement position of the third bevel gear 19 and the fourth bevel gear 20.

[0049] When the air flows upwards from the dehumidifying cylinder 28 after being adsorbed, the air can be guided to flow to one side by the guide block 56, and when the air enters the connection position between the top end of the dehumidifying cylinder 28 and the long tube 6, the air flow can drive the plurality of groups of arc-shaped blades 15 to rotate. Due to the presence of the guide block 56, the area of the connection position between the top end of the dehumidifying cylinder 28 and the long tube 6 can be reduced, so that the flow rate of the steam can be increased by the narrow tube effect, and the steam can drive the arc-shaped blades 15 to rotate, while the arc-shaped blades 15 remain to rotate in one direction. The rotation of the arc-shaped blades 15 can drive the round rod 14 and the first bevel gear 16 to rotate, and the rotation of the first bevel gear 16 can drive the second bevel gear 17 at the bottom and the long rod 18 to rotate together. Since the plurality of groups of arc-shaped blades 15 are arranged at the center of the long rod 18, the rotation of the arc-shaped blades 15 will not affect the rotation of the long rod 18. The third bevel gear 19 arranged on the outer wall of the long rod 18 can rotate with the long rod 18, and the rotation of the third bevel gear 19 can drive the fourth bevel gears 20 on both sides and the stirring plates 21 to rotate together. The protective shell can protect the engagement between the third bevel gear 19 and the fourth bevel gears 20. When the two groups of stirring plates 21 rotate in opposite directions, the silica gel adsorption particles in the placing cylinder 13 can be fully stirred, which is beneficial to the uniform adsorption of moisture on the surface of the silica gel adsorption particles, thereby improving the efficiency of adsorbing humid air. In addition, the round holes formed in the stirring plates 21 can allow some silica gel particles to pass through the round holes when the stirring plates 21 are stirred, which can reduce the resistance of the stirring plates 21.

[0050] As Figure 3 , Figure 10 and Figure 12The heating structure includes contact heads 22 fixed to the outer wall of the placing cylinder 13, the contact heads 22 are provided in multiple groups and are distributed circumferentially on the outer wall of the placing cylinder 13, one end of the contact head 22 penetrates the dehumidifying cylinder 28, the outer wall of the contact head 22 is fixed with a conducting ring 25, the outer wall of the conducting ring 25 is fixed with a heating ring 23, the top end of the heating ring 23 is fixed with a heater 24, the outer wall of the conducting ring 25 is fixed with a crossbar 26, the crossbar 26 is fixed at the center of the multiple groups of heat dissipation fins 5, one side of the crossbar 26 is fixed with a fit piece 27, the fit piece 27 is fixed on one side of the lamp body 1, and the contact head 22, the conducting ring 25, the crossbar 26, the fit piece 27 and the placing cylinder 13 are all made of heat-conducting materials.

[0051] After the air is adsorbed, 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 close the top end and the bottom of the long pipe 6. The multiple groups of heat dissipation fins 5 can be connected in series through the crossbar 26, so that the heat on the heat dissipation fins 5 is transferred to the crossbar 26, and the fit piece 27 is also conducive to transferring the heat on one side of the lamp body 1 to the conducting ring 25 through the crossbar 26, which can accelerate the heat dissipation of the lamp body 1, and utilize the residual heat generated by the heat dissipation fins 5 and one side of the lamp body 1 to preheat the conducting ring 25, which is conducive to saving energy and preventing the silica gel adsorption particles from drying out due to rapid heating. Then, the heater 24 is started to heat the heating ring 23, and the temperature is transferred to the conducting ring 25. Since the transfer ring is connected to the placing cylinder 13 through multiple contact heads 22, and the transfer ring, the contact head 22 and the placing cylinder 13 are all made of heat-conducting materials, the temperature generated by the heating ring 23 can be transferred to the placing cylinder 13 through the transfer ring and the contact head 22, so as to heat the silica gel adsorption particles in the placing cylinder 13. After the silica gel adsorption particles are heated, the water adsorbed by the silica gel adsorption particles is separated out, and the silica gel adsorption particles can be used for adsorption again after cooling.

[0052] As Figure 3 and Figure 8 The drying mechanism further includes a processing structure and a closing structure, the processing structure includes a side pipe 29 fixed to one side of the long pipe 6, the bottom of the side pipe 29 is fixed with a connecting pipe 30, the connecting pipe 30 is fixed to one side of the long pipe 6, the bottom of the connecting pipe 30 is provided with a third one-way valve 40, the outer wall of the side pipe 29 is fixed with a threaded pipe 37, the bottom of the threaded pipe 37 is fixed with a condensing machine 38, the bottom of the condensing machine 38 is fixed with a supporting plate 39, and the supporting plate 39 is fixed to one side of the lamp body 1.

[0053] When the silica gel adsorbent needs to be dehydrated, the long tube 6 at the top of the dehumidification cylinder 28 can be closed by the closing structure, and one side of the side tube 29 is opened. After the silica gel adsorbent is heated, the moisture in the silica gel adsorbent is converted into water vapor and flows upward. When the water vapor flows upward, it is guided by the guide block 56 and flows into the long tube 6 on one side. During the flow process, the arc-shaped blade 15 slowly rotates, and the stirring plate 21 is turned over through the structures of the round rod 14, the first bevel gear 16, the second bevel gear 17, etc. When the silica gel adsorbent particles are heated, the stirring plate 21 is turned over to make the silica gel adsorbent particles evenly heated. Since the closing structure blocks the inside of the long tube 6, the water vapor entering the long tube 6 flows into the inside of the side tube 29. The refrigerant is injected into the threaded tube 37 by starting the condensing machine 38, so that the temperature in the threaded tube 37 is lower than the normal temperature. The threaded tube 37 is arranged on the outer wall of the side tube 29, so that the temperature in the inside of the side tube 29 can be reduced. When the water vapor enters the inside of the low-temperature side tube 29, it is condensed and flows downward into the connecting tube 30 by gravity. After the water is gathered, the third one-way valve 40 is opened, so that the condensed water flows into the inner wall of the long tube 6 and flows downward into the inclined tube 9 and the storage tank 10 by gravity.

[0054] As Figure 3 and Figure 11 The closing structure includes a short rod 31 rotatably connected to the inner wall of the long tube 6. One side of the short rod 31 is fixedly connected with a plug 32. The inner wall of the long tube 6 is fixedly connected with a fitting sleeve 33. The fitting sleeve 33 is provided in two groups. The other group of the fitting sleeve 33 is fixedly connected to the inner wall of the side tube 29. The plug 32 is fitted on one side of one group of the fitting sleeve 33. One side of the short rod 31 protrudes from the long tube 6. One end of the short rod 31 is fixedly connected with a square plate 34. One side of the side tube 29 is fixedly connected with a first magnet 35. The square plate 34 is made of iron. The square plate 34 is arranged at the top of the first magnet 35. One side of the long tube 6 is fixedly connected with a second magnet 36.

[0055] When it is needed to close the long tube 6 above the dehumidification cylinder 28, the square plate 34 is pushed to turn upward and be fixed with the first magnet 35. When the square plate 34 is turned, the short rod 31 and the plug 32 are turned together, so that the plug 32 is gradually turned upward from one side of the side tube 29. When the square plate 34 is turned by 90 degrees, the other side of the square plate 34 is attracted by the second magnet 36, and the positions of the square plate 34, the short rod 31 and the plug 32 are fixed. At this time, the plug 32 is arranged in one group of the fitting sleeve 33 in the inside of the long tube 6, so that the long tube 6 is closed and one side of the side tube 29 is opened. The sealing performance of the plug 32 is improved by the fitting sleeve 33.

[0056] As Figure 7The bottom of the long rod 18 extends and places the cylinder 13. The bottom of the long rod 18 is fixedly connected with a long strip blade 41. The outer wall of the long strip blade 41 is fixedly connected with a circular ring 42. The bottom of the circular ring 42 is fixedly connected with a fling needle 43. The bottom of the fling needle 43 is inclined to the center. The bottom of the fling needle 43 is arranged at the connection between the long tube 6 and the connecting tube 30.

[0057] When the humid air inside the lamp body 1 is dehumidified, the humid air passes through the long strip blade 41, which drives the long strip blade 41 to rotate. The rotation direction of the long strip blade 41 is consistent with that of the long rod 18, which can improve the power of the rotation of the long rod 18. The circular ring 42 and the two groups of fling needles 43 rotate together with the long strip blade 41. Since the fling needle 43 is arranged at the connection between the long tube 6 and the connecting tube 30, and there is a gap between the bottom of the fling needle 43 and the inner wall of the long tube 6, the fling needle 43 contacts the residual water droplets on the inner wall of the long tube 6 when rotating, and flings the water droplets downward after contacting the water droplets. This can make the residual water droplets at the connection between the connecting tube 30 and the long tube 6 fall off. Since the bottom of the fling needle 43 is inclined to the center, it is convenient for the water droplets to be flung downward to the center under the action of gravity and centrifugal force, which is more conducive to the downward falling of the water droplets and prevents the residual water droplets from affecting the adsorption effect of the silica gel adsorption particles on the humid air at the bottom of the cylinder 13.

[0058] As shown in Figure 5 and Figure 13 , the collecting mechanism is used for collecting the condensed water condensed by the water vapor evaporated by the heated silica gel particles. The collecting mechanism comprises an inclined pipe 9 fixedly connected to the bottom of the long tube 6. The bottom of the inclined pipe 9 is fixedly connected with a storage tank 10. The bottom of the storage tank 10 is fixedly connected with a collecting box 44. The top end of the collecting box 44 is rotationally connected with a sealing plate 45 through a rotating shaft. One side of the collecting box 44 is fixedly connected with a hydraulic rod 46. The output end of the hydraulic rod 46 is fixedly connected with a connecting plate 47. The top end of the connecting plate 47 is fixedly connected with a push rod 48. 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 between the push rod 48 and the collecting box 44. One end of the push rod 48 is fixedly connected with a push plate 49. The push plate 49 is T-shaped. One end of the collecting box 44 is fixedly connected with a transmission pipe 50. The transmission pipe 50 extends into the inner wall of the lamp body 1. The inner wall of the lamp body 1 is fixedly connected with a sleeve frame 51. The transmission pipe 50 is fixedly connected to the bottom of the sleeve frame 51. The top end of the collecting box 44 is fixedly connected with an injection pipe 52.

[0059] Since the bottom of the storage tank 10 is communicated with the collecting box 44, the water in the storage tank 10 can flow into the collecting box 44, when the interior of the lamp body 1 needs to be cooled, the hydraulic rod 46 can be started to drive the connecting plate 47 to move to one side of the collecting box 44, and the connecting plate 47 can drive the push rod 48 and the push plate 49 to move together when moving, the side of the push plate 49 is provided with a sealing gasket, which can prevent the accumulated water from flowing to the other side of the collecting box 44 when moving, and the push plate 49 is T-shaped, so that the sealing plate 45 can be lifted upward when the push plate 49 moves, so as to close the connecting part between the storage tank 10 and the collecting box 44, preventing water from flowing into the storage tank 10 under pressure, and the water can move into the transmission pipe 50 after being pressed, and flow into the inner wall of the sleeve frame 51, 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 cool the interior of the lamp body 1, and when the accumulated water is insufficient but still needs to be cooled, water can be added to the collecting box 44 through the injection pipe 52.

[0060] As Figure 12 , the bottom of the cross rod 26 is fixedly connected with a heat-conducting rod 53, one side of the lamp body 1 is fixedly connected with a storage box 54, the inner wall of the storage box 54 is provided with plant essential oil, and the bottom of the heat-conducting rod 53 is arranged on the inner wall of the storage box 54.

[0061] When the cross rod 26 absorbs the heat of a plurality of groups of heat dissipation fins, the lower heat-conducting rod 53 can be heated, and when the heat-conducting rod 53 is heated, the temperature can be transmitted to the storage box 54, so that the plant essential oil in the storage box 54 is heated, and the plant essential oil after being heated can improve the efficiency of volatilization, so that the plant essential oil can be volatilized to the air around the lamp body 1 to drive the flying insects away, preventing more flying insects from gathering around the lamp body 1 due to phototaxis.

[0062] As Figure 6 , the top end of the long pipe 6 is fixedly connected with a flow divider 55, the flow divider 55 is provided with four groups and is symmetrically distributed on the bottom and top of the long pipe 6, and the bottom of the support frame 2 is fixedly connected with a support leg 3.

[0063] By arranging two groups of flow dividers 55 on the top and bottom of the long pipe 6, when the humid air is sucked into the bottom of the long pipe 6, the range of sucking humid air can be increased by the two groups of flow dividers 55, and when the dry air is transmitted from the top end of the long pipe 6 into the space between the reflector and the glass cover, the dry air can be uniformly injected by the two groups of flow dividers 55 above.

[0064] Working principle: to solve the problem of outdoor lighting lamps glass cover inside the humid air easy to form water mist, in the outdoor use LED lighting lamps, can pull the handle 4 to the lamp body 1 is lifted, and the lamp body 1 is moved to the appropriate location, then can be adjusted according to the needs of the illumination angle of the lamp body 1, while the lamp body 1 in operation, can be beneficial to the back of the lamp body 1 by a plurality of groups of heat dissipation fins 5 for heat dissipation, when the air between the reflector and the glass cover needs to be dehumidified, first stop the operation of the lamp body 1, then start the fan 8, because the fan 8 is arranged at the top of the long tube 6, so the fan 8 can produce negative pressure in the inside of the long tube 6 when starting, and the air between the reflector and the glass cover is sucked into the bottom of the long tube 6, when the humid air or water enters the bottom of the long tube 6, the second check valve 12 can be opened, the closure between the bottom of the long tube 6 and the inside of the lamp body 1 is removed, so that the air enters the inside of the long tube 6 from below, if there is water between the reflector and the glass cover, the water can flow into the inclined pipe 9 and the storage tank 10 through the bottom of the long tube 6, so as to collect the water, under the action of the suction force of the fan 8, the humid air can enter the dehumidification cylinder 28, and pass through the placing cylinder 13, the silica gel adsorption particles in the placing cylinder 13 can adsorb the moisture, and the dry air after adsorption can continue to flow upwards in the long tube 6, and open the first check valve 11, so that the dry air reenters between the reflector and the glass cover, so as to reduce the humidity of the air between the reflector and the glass cover, prevent fogging and water caused by humidity;

[0065] When the air flows upward from the dehumidification cylinder 28 after being adsorbed, the air can be guided to flow to one side by the guide block 56, and when the air enters the connection between the top end of the dehumidification cylinder 28 and the long tube 6, the air flow can drive the multiple sets of arc-shaped blades 15 to rotate. Due to the presence of the guide block 56, the area of the connection between the top end of the dehumidification cylinder 28 and the long tube 6 is reduced, thereby increasing the flow rate of the steam through the narrow tube effect, which can promote the steam to drive the arc-shaped blades 15 to rotate while keeping the arc-shaped blades 15 rotating in one direction. When the arc-shaped blades 15 rotate, the circular rod 14 and the first bevel gear 16 are driven to rotate, and the first bevel gear 16 drives the second bevel gear 17 at the bottom and the long rod 18 to rotate at the same time. Since the multiple sets of arc-shaped blades 15 are provided with openings at the center, the rotation of the arc-shaped blades 15 does not affect the rotation of the long rod 18. The third bevel gear 19 provided on the outer wall of the long rod 18 rotates with the long rod 18, and the third bevel gear 19 drives the fourth bevel gears 20 and the stirring plates 21 on both sides to rotate at the same time. When the two sets of stirring plates 21 rotate in opposite directions at the same time, the silica gel adsorption particles in the placement cylinder 13 can be fully stirred, which is beneficial to the uniform adsorption of moisture in the air on the surface of the silica gel adsorption particles, thereby improving the efficiency of adsorbing humid air. At the same time, the circular holes provided on the stirring plates 21 can allow some silica gel particles to pass through the circular holes when the stirring plates 21 are stirred, which can reduce the resistance of the stirring plates 21. Since the humid air enters the dehumidification cylinder 28 through the long strip blades 41, the long strip blades 41 are driven to rotate, and the rotation direction of the long strip blades 41 is consistent with that of the long rod 18, which can improve the power of the long rod 18. After the adsorption of the air 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 close the top end and the bottom of the long tube 6.

[0066] By pushing the square plate 34 to flip up, the fixation with the first magnet 35 can be released. When the square plate 34 is flipped, it will drive the short rod 31 and the plug 32 to rotate together, so that the plug 32 gradually flips up 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 attracted 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 is against a set of fitting sleeves 33 inside the long pipe 6, which can close the long pipe 6 and open one side of the side pipe 29. Through the cross rod 26, multiple sets of heat dissipation fins 5 can be connected in series, so that the heat on the heat dissipation fins 5 is transferred to the cross rod 26. At the same time, the fitting sheet 27 is also conducive to transferring the heat on one side of the lamp body 1. The cross rod 26 can transfer the heat to the heat conduction rod 53 and heat the plant essential oil in the storage box 54, thereby achieving the effect of insect repelling. At the same time, the heat will be transferred to the conduction ring 25, which can accelerate the heat dissipation of the lamp body 1 and use the residual heat generated by the heat dissipation fins 5 and one side of the lamp body 1 to preheat the conduction ring 25, which is conducive to saving energy and preventing the silica gel adsorption particles from drying out due to overheating. Then start the heater 24 to heat 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, contact head 22 and placement cylinder 13 are all heat-conducting materials, the temperature generated by the heating ring 23 can be transferred to the placement cylinder 13 through the transfer ring and contact head 22, which is convenient for heating the silica gel adsorption particles in the placement cylinder 13. After heating, the silica gel adsorption particles will make the water they adsorb into water vapor and separate out. After dehydration, the silica gel adsorption particles can be used repeatedly. When the water vapor flows upward, it will be guided by the guide block 56 to flow into the long pipe 6 on one side. In the process of flowing, the arc-shaped blade 15 will rotate slowly, and the stirring plate 21 will be flipped by the structures such as the circular rod 14, the first bevel gear 16 and the second bevel gear 17. When the silica gel adsorption particles are heated, the stirring plate 21 will be flipped to make the silica gel adsorption particles evenly heated. Since the plug 32 blocks 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 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 and flow into the connecting pipe 30 under the action of gravity. After the water flows downward, it will push open the third one-way valve 40, so that the condensed water flows into the inner wall of the long pipe 6 and flows into the inclined pipe 9 and the storage tank 10 under the action of gravity.

[0067] In the subsequent dehumidification operation again, the ring 42 will rotate with the long strip blade 41 and the long rod 18, the two groups of the needle 43 will rotate with the ring 42, the needle 43 will contact the residual water droplets on the inner wall of the long tube 6 when rotating, and the water droplets will be thrown downward after contacting the water droplets, which can make the residual water droplets at the connection between the connecting pipe 30 and the long tube 6 fall off, at the same time, the bottom of the needle 43 is inclined to the center, so as to facilitate the water droplets to be thrown downward to the center under the action of gravity and centrifugal force, which is more conducive to the water droplets to fall downward into the storage tank 10, preventing the residual water droplets from affecting the adsorption effect of silica gel adsorption particles on humid air, and at the same time, the steam driven long rod 18 can also drive the needle 43 to rotate to clean the residual water droplets, preventing the water droplets from gathering below the placing cylinder 13 and wasting the adsorption effect of silica gel. After the silica gel is dried, the lamp body 1 needs to be cooled during subsequent operation, the hydraulic rod 46 can be retracted to drive the connecting plate 47, the push rod 48 and the push plate 49 to move together, the side surface of the push plate 49 is provided with a sealing gasket, which can prevent water from flowing to the other side of the collection box 44 during movement, and the push plate 49 is T-shaped, so that the sealing plate 45 can be lifted upward when the push plate 49 moves, so as to close the connection between the storage tank 10 and the collection box 44, preventing water from flowing into the storage tank 10 under pressure, and the water will move into the transmission pipe 50 after being pressed, and then flow into the inner wall of the sleeve frame 51, 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, and when the water is insufficient but still needs to be cooled, water can be added to the collection box 44 through the injection pipe 52, so as to continuously cool the inside of the lamp body 1.
