[0032] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0033] like Figures 1 to 5As shown in the figure, the present invention provides an outdoor energy-saving and high-efficiency air heater structure, including a protective shell 1. A movable plate 11 is slidably connected to the bottom wall of the inner wall of the protective shell 1. A heater body 12 is fixedly connected to the upper end face of the movable plate 11. The protective shell 1 protects the heater body 12 from rain damage and from impacts by heavy objects. A sealing plate 13 is fixedly connected to one side of the heater body 12. Two symmetrical connecting blocks 14 are slidably connected to the side of the sealing plate 13 away from the heater body 12. A positioning block 15 is provided on the lower end face of the connecting block 14. The positioning block 15 is fixedly connected to the protective shell 1. A locking groove 16 is provided on the upper end face of the positioning block 15. A movable connecting block 15 is provided in the locking groove 16. A locking pin 17 is connected to a connecting block 14. A guide rod 18 is fixedly connected to the upper end face of the connecting block 14. A fixing block 19 is slidably connected to the outer wall of the guide rod 18. The fixing block 19 is fixedly connected to the sealing plate 13. A spring 20 is sleeved on the outer wall of the guide rod 18. The two ends of the spring 20 are fixedly connected to the connecting block 14 and the fixing block 19, respectively. With the movement of the two connecting blocks 14, the corresponding locking pin 17 moves upward, causing the guide rod 18 to interact on the fixing block 19. This causes the connecting block 14 to squeeze the spring 20, thereby achieving quick unlocking. This facilitates the movement of the moving plate 11, which in turn slides the heater body 12, thereby removing the heater body 12 from the protective shell 1, thus facilitating the cleaning of the heater body. For the maintenance of the body 12, two symmetrical sliding grooves 31 are provided on the inner bottom wall of the protective shell 1. Sliding rods 32 are slidably connected in the sliding grooves 31 and are fixedly connected to the moving plate 11. The use of the two sliding grooves 31 and the two sliding rods 32 can limit and stabilize the moving plate 11, ensuring the stability of the moving plate 11 during movement. A limiting groove 51 is provided on the inner bottom wall of the protective shell 1, located between the two sliding grooves 31. A limiting block 52 is slidably connected in the limiting groove 51 and is fixedly connected to the moving plate 11. The use of the limiting groove 51 and the limiting block 52 can limit the moving plate 11 and prevent the moving plate 11 from detaching from the protective shell 1. A sealing plate 13 is provided on the side away from the heater body 12. There are two symmetrical guide grooves 41, and guide blocks 42 are slidably connected within the guide grooves 41. The guide blocks 42 are fixedly connected to the connecting block 14. The use of the two guide grooves 41 and the two guide blocks 42 can guide the connecting block 14, ensuring that the connecting block 14 maintains a vertical up-and-down movement trajectory during the sliding process of lifting and lowering. An exhaust pipe 61 is fixedly connected to the side of the heater body 12 that contacts the sealing plate 13. The exhaust pipe 61 is fixedly connected to the sealing plate 13. An air inlet pipe 62 is fixedly connected to the side of the heater body 12 away from the exhaust pipe 61. An adapter groove 63 is opened on the side of the protective shell 1 away from the sealing plate 13. The adapter groove 63 is adapted to the air inlet pipe 62. A dustproof net 64 is fixedly connected to the air inlet pipe 62.Air can enter the heater body 12, and the heater body 12 heats the air, causing the hot air to be discharged from the exhaust pipe 61, thus heating the surrounding air. A connecting rod 71 is fixedly connected between the two connecting blocks 14, allowing simultaneous movement of both connecting blocks 14 for easy operation. Ventilation slots 81 are provided on both sides of the protective shell 1, with filters 82 installed at each slot. The filters 82 are fixedly connected to the protective shell 1, and a rain cover 83 is fixedly connected above the filters 82. The use of the two ventilation slots 81 allows for heat dissipation within the protective shell 1, and the two filters 82 prevent external dust from entering.

[0034] The working principle and usage process of this utility model are as follows: In use, firstly, air can be introduced into the heater body 12 through the air inlet pipe 62, and the heated air is discharged from the exhaust pipe 61. With the use of the protective shell 1, the heater body 12 can be protected to prevent rain or heavy objects from damaging it. When maintenance of the heater body 12 is required, the connecting rod 71 is raised, which slides the two connecting blocks 14 upward and moves the corresponding locking pins 17 upward, thereby disengaging the locking pins 17 from the locking grooves 16. This makes it easy to move the moving plate 11 out of the protective shell 1, facilitating the maintenance of the heater body 12. This completes the entire usage process of the air heater body 12.
