[0031] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0032] An LED light for gardening, see Figure 1-Figure 4, including a lamp pole 1, an LED lamp tube 3 is installed on the upper part of the lamp pole 1, an outer rhombus lampshade 2 is connected to the upper part of the lamp pole 1, the outer rhombus lampshade 2 covers the LED lamp tube 3, and a cleaning mechanism for cleaning the outer surface of the outer rhombus lampshade 2 is provided on the upper part of the outer wall of the lamp pole 1, and the cleaning mechanism includes a rotating frame 61 rotatably connected to the upper part of the outer wall of the lamp pole 1, and two scrapers A62 that can move toward and away from the outer rhombus lampshade 2 are symmetrically connected to the rotating frame 61 through a sliding rod, and two springs A63 are symmetrically connected between the scraper A62 and the rotating frame 61, and the springs A63 are symmetrically connected to the upper and lower parts of the scraper A62 and the rotating frame 61. The spring A63 is used to drive the scraper A62 to be close to the outer surface of the outer diamond-shaped lampshade 2. The scraper B64 is connected to the top of the rotating frame 61. The bottom of the scraper B64 contacts the top of the outer diamond-shaped lampshade 2. A motor 65 is installed on the upper part of the outer wall of the lamp pole 1. The motor 65 is located below the rotating frame 61. A gear transmission assembly 66 is connected between the bottom of the rotating frame 61 and the output shaft of the motor 65. The gear transmission assembly 66 consists of a small gear and a large gear. The small gear is connected to the output shaft of the motor 65, and the large gear is connected to the bottom of the rotating frame 61. The large gear is meshed with the small gear. The motor 65 and the gear transmission assembly 66 form a driving assembly, a cavity 4 is opened in the upper part of the lamp pole 1, an air inlet connected to the cavity 4 is opened on the top of the outer rhombus lampshade 2, two exhaust holes 5 connected to the cavity 4 are opened at intervals along the circumferential direction on the upper part of the lamp pole 1, and the exhaust holes 5 are located below the outer rhombus lampshade 2. A heat extraction mechanism for extracting the internal heat of the outer rhombus lampshade 2 to the outside is provided in the cavity 4, and the heat extraction mechanism includes a fan 71, an exhaust pipe 72, an air delivery pipe 73 and a conical block 74. The inner lower part of the cavity 4 is installed with three spaced apart from top to bottom through the mounting plate. A fan 71 is provided, and the fan 71 is located on the upper side of the exhaust hole 5. Three groups of exhaust pipes 72 are embedded and installed at intervals from top to bottom on the upper part of the lamp pole 1. The exhaust pipes 72 form a group, and the two exhaust pipes 72 in each group are distributed circumferentially along the lamp pole 1. The exhaust pipe 72 is located above the fan 71. Two air supply pipes 73 are embedded and installed circumferentially on the upper part of the lamp pole 1. The exhaust pipe 72 and the air supply pipe 73 are both located in the outer diamond-shaped lampshade 2. The air supply pipe 73 is located above the exhaust pipe 72. The inner upper part of the cavity 4 is connected with a conical blocking block 74 for guiding the gas into the air supply pipe 73.

[0033] Through the cooperation of the motor 65 and the gear transmission assembly 66, the rotating frame 61 can be driven to rotate, driving the scraper A62 and the scraper B64 to rotate. The rotation of the scraper A62 can scrape off the dust, mosquito secretions and other impurities accumulated on the outer wall of the outer diamond-shaped lampshade 2. The rotation of the scraper B64 can scrape off the dust, mosquito secretions and other impurities accumulated on the top of the outer diamond-shaped lampshade 2, thereby automatically cleaning the outer surface of the outer diamond-shaped lampshade 2, thereby keeping the outer diamond-shaped lampshade 2 clean and improving the lighting effect. There is no need for manual labor to climb to a higher place with the help of a ladder to clean the outer diamond-shaped lampshade 2, thereby saving time and effort and improving safety. When the LED lamp tube 3 is performing lighting work, the fan 71 is controlled to work so as to draw the gas in the outer diamond-shaped lampshade 2 into the cavity 4 in the lamp pole 1 through the exhaust pipe 72. The gas in the cavity 4 is then discharged outwardly through the exhaust hole 5, and the outside gas enters the cavity 4 through the air inlet at the top of the outer diamond-shaped lampshade 2. The cavity 4 can be blocked by the conical block 74 to guide the outside gas entering the cavity 4 to the gas pipe 73. The gas in the gas pipe 73 is then discharged into the outer diamond-shaped lampshade 2. In this way, the internal and external exchange of gas can be realized, so that the gas in the outer diamond-shaped lampshade 2 circulates, so as to realize the automatic external discharge of the internal heat of the outer diamond-shaped lampshade 2, thereby improving the heat dissipation effect, avoiding the accumulation of heat in the outer diamond-shaped lampshade 2 causing the temperature of the LED lamp tube 3 to be too high, and thus extending the service life of the LED lamp tube 3.

[0034] See also Figure 5-Figure 6 A closing mechanism is provided between the outer diamond-shaped lampshade 2 and the scraper B64, and the closing mechanism includes a diamond block 81 connected to the top of the outer diamond-shaped lampshade 2 through a support rod, and the diamond block 81 is located directly above the air inlet at the top of the outer diamond-shaped lampshade 2. The outer wall of the diamond block 81 is sleeved with an inner diamond block 82, and the outer wall of the inner diamond block 82 is spaced apart by two V-shaped guide grooves 85 along the circumferential direction, and the outer wall of the inner diamond block 82 is spaced apart by two arc-shaped slide grooves 86 along the circumferential direction, and the arc-shaped slide groove 86 is located on the upper side of the V-shaped guide groove 85 and is connected to the V-shaped guide groove 85. The two V-shaped guide grooves 85 are both slidably connected with cross bars 84, and the two cross bars 84 are both connected with connecting rods 83, and the bottom of the connecting rod 83 is fixedly connected to the top of the scraper B64.

[0035] Initially, the cross bar 84 is located at the lower part of the V-shaped guide groove 85, and the inner diamond block 82 does not block the air inlet at the top of the outer diamond lampshade 2. When the scraper B64 rotates, the cross bar 84 is driven to rotate through the connecting rod 83. Since the inner diamond block 82 is supported by the diamond block 81 and cannot rotate, and the setting of the V-shaped guide groove 85 allows the cross bar 84 to push the inner diamond block 82 to move downward when the cross bar 84 rotates. After the inner diamond block 82 moves downward, it cooperates with the diamond block 81 to block the air inlet at the top of the outer diamond lampshade 2 to prevent impurities such as dust and mosquito secretions from entering the outer diamond lampshade 2 when the scraper B64 rotates to clean the top of the outer diamond lampshade 2, thereby protecting the LED lamp tube 3 and the fan 71. After the inner diamond block 82 moves downward, it guides the cross bar 84 through the arc-shaped slide groove 86 on it, so that the inner diamond block 82 keeps blocking the air inlet at the top of the outer diamond lampshade 2. When the cross bar 84 turns into the upper part of the V-shaped guide groove 85, the cross bar 84 continues to rotate to push the inner diamond block 82 to move up and reset.

The 7-shaped block 96 is located below the lower fixing ring 92. It should be noted that the pull rope 94, the arc block 95 and the 7-shaped block 96 constitute a locking assembly.

[0037] Initially, the arc block 95 is stuck in the 7-shaped block 96, the annular block 91 is located below the exhaust hole 5, and the spring B93 is in a compressed state. When it is about to rain, the arc block 95 is pulled down to disengage from the 7-shaped block 96, and then the arc block 95 is moved in the direction away from the 7-shaped block 96. The arc block 95 is then released, and under the resetting action of the spring B93, the annular block 91 moves up to block the exhaust hole 5, thereby preventing rainwater from entering the cavity 4 of the lamp pole 1 through the exhaust hole 5 and causing a short circuit between the LED lamp tube 3 and the fan 71. When it is sunny, the arc block 95 is pulled down so that the pull rope 94 pulls the annular block 91 downward to not block the exhaust hole 5, and the spring B93 is compressed accordingly. Finally, the arc block 95 is stuck in the 7-shaped block 96 to lock the annular block 91.

[0039] The mosquito repellent liquid is injected into the accommodating cavity of the cylinder 101 through the liquid injection tube 102, and the annular heating rod 105 is controlled to heat the mosquito repellent liquid so that the mosquito repellent liquid becomes gaseous and is discharged from the through hole at the top of the cylinder 101 and diffused into the air, thereby repelling mosquitoes and preventing people from being bitten by mosquitoes when they stay near the device for entertainment.

[0040] See also Fig. 9 A rain shield 11 is connected to the outer wall of the lamp pole 1, and the rain shield 11 is located above the cylinder 101. The shape of the rain shield 11 is conical. The conical rain shield 11 can block rainwater to prevent rainwater from entering the cylinder 101 through the through hole at the top of the cylinder 101, and the conical rain shield 11 can effectively drain rainwater to keep the rain shield 11 dry and clean.

Since the circular sun visor 13 is designed to be high in the middle and low on the outside, it can effectively drain rainwater and keep the circular sun visor 13 dry and clean.
