As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0016] Please see Figures 1-6 This utility model provides a technical solution: A quick-release heat dissipation housing for a street lamp head includes a circuit board 1, which is embedded and fixed inside a lower cover assembly 3. An upper cover assembly 2 is installed on the upper end of the lower cover assembly 3. The upper cover assembly 2 includes an upper housing 21, with a plug 22 fixedly connected to the inner side of the upper housing 21. A rubber duckbill valve 23 is fixedly connected to the inner side of the plug 22 near the upper end. A vent 24 is provided inside the plug 22. A first rubber sealing ring 26 is fixedly connected to the outer side of the plug 22 near the lower end. The lower cover assembly 3 includes a lower housing 31, with an ear seat 36 fixedly connected to one side of the lower housing 31. A positioning shell 37 is fixedly connected to one side of the ear seat 36. A blind hole 38 is provided inside the positioning shell 37.

[0017] As a further implementation of this solution, a positioning cylinder 32 is fixedly connected to the inner side of the lower housing 31, and a second rubber sealing ring 33 is fixedly connected to the inner side of the positioning cylinder 32. A screw 34 is threadedly connected to the lower housing 31 near the upper end, with the screw 34 located at the right end of the second rubber sealing ring 33. Through the above arrangement, the second rubber sealing ring 33 can achieve sealing protection between the positioning cylinder 32 and the pole, preventing dew and rainwater from seeping into the internal components and causing damage. The screw 34 can effectively prevent relative torsion between the positioning cylinder 32 and the pole, ensuring the stability of the installation structure and improving the overall safety of use. As a further implementation of this solution, a heat dissipation hole is provided near the lower end of the lower housing 31, and a rubber pad 35 is fixedly connected to the top of the lower housing 31. The lower housing 31 is sealed to the upper housing 21 through the rubber pad 35. With the above arrangement, the heat dissipation hole can quickly dissipate the heat generated by the internal components during operation, avoiding the impact of high temperature on the service life of the equipment. The rubber pad 35 can achieve a sealing fit between the lower housing 31 and the upper housing 21, preventing external rainwater and impurities from entering, and ensuring the operational stability of the internal structure. As a further implementation of this solution, a fixing seat 25 is fixedly connected to the outside of the insert 22. One side of the fixing seat 25 is fixedly connected to the inside of the upper housing 21. Through the above arrangement, the fixing seat 25 can strengthen the connection between the insert 22 and the upper housing 21, avoid relative displacement between the two, ensure the stability of the overall structure after installation, and provide support for the reliable realization of subsequent functions such as sealing and magnetic adsorption. As a further implementation of this solution, the insert 22 is aligned vertically with the blind hole 38, and the insert 22 is inserted into the interior of the blind hole 38. The insert 22 is sealed to the positioning shell 37 by the first rubber sealing ring 26. Through the above settings, the precise alignment design of the insert 22 and the blind hole 38 can improve the ease of installation and shorten the assembly time. The first rubber sealing ring 26 can effectively seal the connection between the two, which can prevent the blind hole 38 from communicating with the outside air after the insert 22 is assembled inside the positioning shell 37, thereby ensuring the stability of the insert 22 after insertion. As a further implementation of this solution, the vent 24 is connected to the upper end of the insert 22 and the vent 24 is connected to the inside of the blind hole 38. Through the above setting, the connecting structure allows the gas inside the blind hole 38 to flow smoothly into the upper part of the insert 22 during installation, providing power for the automatic opening of the valve port of the rubber duckbill valve 23. Installation and positioning can be completed without additional operation, improving installation efficiency and ease of operation. As a further implementation of this solution, a first permanent magnet block 27 is fixedly connected to the lower end of the insert 22, and a second permanent magnet block 39 is fixedly connected to the positioning shell 37 near the lower end. The first permanent magnet block 27 and the second permanent magnet block 39 are aligned vertically and magnetically attracted to each other. Through the above arrangement, the alignment design facilitates quick and accurate positioning, improves assembly efficiency, and the magnetic attraction further strengthens the installation stability of the upper shell 21 and the lower shell 31, preventing the insert 22 from detaching from the blind hole 38 during use. At the same time, it assists in quickly completing positioning and assembly, reducing the difficulty of disassembly and assembly.

[0018] Workflow: During installation, firstly, the positioning cylinder 32 is fitted onto the outer side of the end of the pole until the screw hole at the upper end of the positioning cylinder 32 is aligned with the gap at the upper end of the pole. At this point, the positioning cylinder 32 is sealed to the pole by the second rubber sealing ring 33. This seal prevents dew or rainwater from seeping into the upper housing 21 and lower housing 31. Then, the positioning cylinder 32 is fixed to the pole by screws 34. This fixation prevents the positioning cylinder 32 from twisting relative to the pole. Next, the lower parts of the multiple inserts 22 are aligned with the blind holes 38. Then, the inserts 22 are inserted into the blind holes 38. When the first rubber sealing ring 26 contacts the inside of the blind hole 38, the gas inside the blind hole 38 will pass through the seal of the first rubber sealing ring 26. The air duct 24 flows into the upper part of the insert 22. Due to the collision of gas inside the insert 22, the upper valve of the rubber duckbill valve 23 is opened after being pressurized. The gas inside the insert 22 flows out through the rubber duckbill valve 23. When the bottom of the fixing seat 25 is attached to the top of the ear seat 36, the first permanent magnet block 27 and the second permanent magnet block 39 approach each other and are magnetically attracted. Through the magnetic attraction between the first permanent magnet block 27 and the second permanent magnet block 39, the stability of the relative installation of the upper shell 21 and the lower shell 31 can be improved. The upper shell 21 is sealed to the lower shell 31 by the rubber gasket 35. At the same time, the rubber duckbill valve 23 limits the gas flow direction, which can prevent the insert 22 from detaching from the blind hole 38 and improve the safety of use. During disassembly, press the rubber duckbill valve 23 by hand to manually open the valve port at the upper end of the rubber duckbill valve 23. After multiple rubber duckbill valves 23 are opened, the upper housing 21 can be pulled upwards, the insert 22 disengages from the blind hole 38, and the first permanent magnet block 27 and the second permanent magnet block 39 move away from each other, thereby achieving the effect of quickly disassembling the upper housing 21. This disassembly method does not require carrying tools, is easy to operate, and significantly reduces the risk of the device breaking due to improper force, ensuring the integrity of the equipment and the safety of personnel.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
