The air pump A8 and the air pump B12 of the present invention both use the prior art.

The working process of the invention is as follows: in the initial state, the LED lamp 62 is not inserted into each insertion mechanism 60, the slide seat 52 of each insertion mechanism 60 is located at the lowest limit position in the corresponding fixing sleeve 46, the air guide groove 53 on the slide seat 52 is located below the air blowing groove 47, the four air blowing grooves 47 are all closed by the side walls of the slide seat 52, the lower end of the ring sleeve 33 is spaced from the bottom of the ring groove a24, and each air discharge groove 28 is closed by the corresponding baffle 40. All of the pull cords 44 are under tension and both of the springs C50 in each of the plug mechanisms 60 are under tension. Spring A38 and spring B41 are both in a compressed state. The two round rods 57 on the slide 52 of each plug-in mechanism 60 are each in abutment with the driving ramp 18 on the corresponding slide 17.

Before the LED lamp 62 is plugged into the plugging mechanism 60, the push rod 21 is pushed into the seat shell a1, the push rod 21 drives all the slide blocks 17 to synchronously slide in the seat shell a1 through the connecting frame 20, and the two slide blocks 17 corresponding to the slide base 52 in each plugging mechanism 60 respectively interact with the corresponding round rods 57, so that the slide bases 52 in all the plugging mechanisms 60 synchronously slide axially in the corresponding fixing sleeves 46, the air guide grooves 53 on the slide bases 52 are communicated with the round grooves 27, the air guide grooves 53 are opposite to the four air blowing grooves 47, and the four air blowing grooves 47 are gradually opened. When the push rod 21 is pushed to the limit, the slide blocks 17 move to the limit, and the round rod 57 just reaches the upper end face of the corresponding slide block 17, at which time the slide 52 of the plugging mechanism 60 moves to the limit in the fixing sleeve 46, and the two springs C50 which restore the slide 52 are further extended.

When the LED lamp 62 is plugged into the plugging mechanism 60, the two plugs 64 of the LED lamp 62 are respectively plugged into the two copper sleeves 54 through the sockets 59 on the dustproof pad 58, and the dustproof pad 58 is tightly attached to the side wall of the plug 64 after the plug 64 is plugged into the copper sleeve 54, so as to prevent dust from falling into the copper sleeve 54. During the process of plugging the LED lamp 62 into the plugging mechanism 60, the heat dissipation plate 63 of the LED lamp 62 presses the ring sleeve 33 downward through the ring plate 34, so that the ring sleeve 33 moves toward the seat shell a1 relative to the cylindrical seat 23, the ring sleeve 33 drives the four guide rods 36 to move synchronously, and the spring a38 for returning each guide rod 36 is further compressed. The four guide rods 36 pull the four shutters 40 by the boxes 37 and the four pull cords 44 connected to the boxes 37 to simultaneously and rapidly open the four exhaust slots 28, and the two springs B41 that return each shutter 40 are further compressed. When the heat dissipation plate 63 of the LED lamp 62 abuts against the dustproof pad 58 at the upper end of the sliding seat 52, the two plugs 64 are completely inserted into the two copper sleeves 54 and complete the insertion of the LED lamp 62 onto the insertion mechanism 60, at this time, the lower end of the ring sleeve 33 abuts against the bottom of the annular groove a24 on the cylindrical seat 23, and the sealing pads 35 at the upper and lower end surfaces of the ring plate 34 are respectively in sealing fit with the heat dissipation plate 63 of the LED lamp 62 and the upper end surface of the cylindrical seat 23.

After the LED lamp 62 is completely inserted into the inserting mechanism 60, the air pump A8 and the air pump B12 are simultaneously activated, the air pump A8 sucks air with lower temperature through the air suction pipe a11 on the air pump a, and blows the air into the four air blowing grooves 47 on the inner wall of the fixing sleeve 46 through the air outlet pipe a9 on the air pump a, the air entering the circular groove 27 from the four air blowing grooves 47 is guided and reflected by the air guide grooves 53 on the side wall of the sliding base 52 to reach the heat dissipation plate 63 of the LED lamp 62, and the air blown to the heat dissipation plate 63 is guided to absorb the heat dissipated by the operation of the LED lamp 62. Meanwhile, the air pump B12 pumps the air which absorbs heat from the heat dissipation plate 63 in the circular groove 27 through the branch pipe 10 on the air suction pipe B13 and the four air exhaust grooves 28 communicated with the circular groove 27, and the air pump B12 sprays the pumped air which absorbs heat to the heat dissipation plate 16 at one end of the seat shell B22 through the spray head 15 on the air outlet pipe B14 to perform effective heat dissipation. In the process that the LED lamp 62 is continuously inserted into the inserting mechanism 60, the LED lamp 62 continuously works to dissipate heat, and the air pump A8 and the air pump B12 continuously work to dissipate heat of the heat dissipation plate 63 of the LED lamp 62 continuously. The circular groove 27 at the upper end of the cylindrical seat 23 is sealed by the heat dissipation plate 63 to form a space isolated from the outside, so that the heat dissipation effect of the opened exhaust groove 28 is prevented from being influenced by blockage caused by entering dust and sand in a wind and sand environment.

After the LED lamp 62 is used, the LED lamp 62 is pulled away from the plugging mechanism 60, and in the process of pulling the LED lamp 62 away from the plugging mechanism 60, the four guide rods 36 are reset under the reset action of the corresponding springs a38, the four guide rods 36 drive the ring sleeve 33, the ring plate 34 and the frame 37 to reset, the four pull ropes 44 are loosened simultaneously, and the four baffles 40 are reset under the reset action of the corresponding two springs B41 and gradually close the corresponding exhaust grooves 28 respectively. When the LED lamp 62 is completely pulled out of the plugging mechanism 60, the ring sleeve 33 and the baffles 40 are completely reset, and the four exhaust grooves 28 are completely closed by the corresponding baffles 40, so as to ensure that the exhaust grooves 28 on the present invention are not blocked by dust, sand and stone entering the exhaust grooves in a limited state.

When the LED lamp 62 is completely pulled out of the plugging mechanism 60, the push rod 21 is pulled out of the seat shell a1, the push rod 21 drives all the slide blocks 17 to reset through connection, along with the reset of the slide blocks 17, the slide base 52 in each plugging mechanism 60 resets under the reset action of the corresponding spring C50, the four air blowing grooves 47 on the inner wall of the fixing sleeve 46 are closed by the slide base 52 again, and the air guide grooves 53 on the slide base 52 enter the fixing sleeve 46 again. The dust-proof pad 58 shields the two copper sleeves 54 on the sliding base 52 again, so that the copper sleeves 54 in the invention can not enter dust and sand in the idle state.

In conclusion, the beneficial effects of the invention are as follows: after the plugging mechanism 60 and the LED lamp 62 are plugged and matched, the four exhaust grooves 28 at the bottom of the circular groove 27 are completely opened, and meanwhile, the circular groove 27 at the upper end of the cylindrical seat 23 is sealed into an independent space by the heat dissipation plate 63 of the LED lamp 62, so that the opened exhaust grooves 28 cannot enter dust, gravels and stones in a wind and sand environment. After the LED lamp 62 is completely inserted into the inserting mechanism 60, the air pump A8 blows air with a lower temperature onto the heat dissipation plate 63 of the LED lamp 62 and absorbs heat generated by the LED lamp 62, and the air pump B12 sucks the air absorbed by the heat dissipation plate 63 to the heat dissipation plate 16 at one end of the seat shell B22 to perform effective heat dissipation, so that the socket realizes effective heat dissipation of the LED lamp 62 while preventing dust.

When the LED lamp 62 is pulled out of the plugging mechanism 60, the four exhaust grooves 28 at the bottom of the circular groove 27 of the cylindrical seat 23 are closed, the two copper sleeves 54 on the sliding seat 52 are shielded by the dustproof pad 58 closed by the socket 59, so that the copper sleeves 54 and the exhaust grooves 28 in the invention are prevented from entering dust and sand in a sand wind environment in an idle state, and the inner walls of the exhaust grooves 28 and the copper sleeves 54 in the invention are ensured to be clean.
