[0037] The present invention will be further described below with reference to the accompanying drawings.
[0038] like Figures 1 to 7As shown, this utility model provides a wall-mounted waterproof heater, including a body 1. The body 1 is mounted on the wall via a wall-mounting bracket 41. The wall-mounting bracket 41 is rotatably mounted with an installation guide rail 5 via a linkage structure. The upper end of the installation guide rail 5 is provided with an open installation groove 51. The body 1 is provided with an installation protrusion 14, which is inserted into the installation groove 51 to allow the body 1 to be installed and removed along the inclined direction, reducing the installation height limitation and facilitating installation in confined spaces and at higher positions. The guide protrusion is provided with a limiting protrusion 142, and the installation guide rail 5 is provided with a corresponding limiting groove 52. The limiting protrusion 142 is inserted into the limiting groove 52 to ensure proper installation and improve connection stability. The inclination angle of the installation guide rail 5 relative to the wall-mounting bracket 41 is 10°-15°, ensuring safety while maintaining installation convenience.
[0039] like Figure 2 , Figure 7 and Figure 8 As shown, the front end of the unit 1 is provided with an air outlet slot 11, and the rear end is provided with an air inlet slot 12. The interior of the unit 1 has a warm air chamber 13 that communicates with the air inlet slot 12 and the air outlet slot 11. A fan assembly 2 is installed in the warm air chamber 13. A heating element 3 is provided between the fan assembly 2 and the air outlet slot 11. The fan assembly 2 includes a motor and an impeller driven by the motor. The impeller guides the air to the heating element 3 for heating and outputs it from the air outlet slot 11. The heating element 3 is installed in a heating housing 15 inside the unit 1. A front heat insulation cover 16 is installed on the front side of the heating housing 15, and a rear heat insulation cover 17 is installed on the unit 1. The two are inserted and fitted together to form the warm air chamber 13. A stepped portion 171 that cooperates with the heating housing 15 is provided on the rear heat insulation cover 17, and a waterproof slot 161 is provided on the front heat insulation cover 16. The stepped portion 171 and the waterproof slot 161 are inserted and fitted together, thereby improving the overall sealing and waterproof performance, preventing water vapor or condensate from entering the interior, and ensuring safe operation.
[0040] like Figures 3 to 6As shown, the linkage structure includes a first movable rod 42 and a second movable rod 43 hinged to the wall-mount bracket 41, and a third movable rod 44 hinged to the middle of the mounting rail 5. The middle of the mounting rail 5 is hinged to the third movable rod 44, and the other end of the third movable rod 44 is hinged to a slider 45 inside the wall-mount bracket 41. The slider 45 can slide within the groove 411 of the wall-mount bracket 41. One end of the first movable rod 42 is hinged to the wall-mount bracket 41, and the other end is hinged to the bottom of the mounting rail 5. One end of the second movable rod 43 is hinged to the wall-mount bracket 41. The other end of the bracket 41 is hinged to the middle of the third movable rod 44. When the mounting guide rail 5 is unlocked, the slider 45 moves downward, causing one end of the third movable rod 44 to move downward. Since the second movable rod 43 is hinged to the third movable rod 44, the first movable rod 42 and the second movable rod 43 rotate on the wall-mounted bracket 41. The end of the third movable rod 44 away from the wall-mounted bracket 41 moves outward, thereby causing the mounting guide rail 5 to rotate around the first movable rod 42, so that the mounting guide rail 5 can rotate smoothly and achieve fine-tuning of the angle, avoiding installation wobbling.
[0041] like Figures 3 to 6 As shown, a locking mechanism 6 is provided inside the wall-mounted bracket 41. The locking mechanism 6 is used to fix the mounting rail 5 in a vertical position after adjusting the angle of the mounting rail 5 to ensure the overall stability after installation. The locking mechanism 6 includes a rotating shaft 61 and a locking rod 62 installed on the top of the wall-mounted bracket 41. The middle part of the locking rod 62 is rotatably connected to the wall-mounted bracket 41 through the rotating shaft 61. The front end of the locking rod 62 is provided with a ratchet part 621. The top end of the mounting rail 5 is provided with a locking pin 141. The ratchet part 621 and the locking pin 141 lock together. The locking lever 62 is fitted with a torsion spring 63, one end of which abuts against the wall-mounted bracket 41 and the other end against the locking lever 62, so that the locking lever 62 always maintains a downward rotation trend, ensuring that the ratchet 621 and the locking pin 141 are reliably engaged, preventing loosening due to vibration. The rear end of the locking lever 62 is provided with a connecting shaft 64, and a pull ring 65 is provided on the connecting shaft 64. The user can release the lock by pulling the pull ring 65. The operation is simple and convenient, and it is especially suitable for narrow installation spaces.
[0042] like Figure 2 and Figure 7 As shown, a control circuit board 7 is installed inside the body 1, and a knob 18 electrically connected to it is provided on the body 1. The knob 18 and the body 1 are connected by a waterproof boss 19 to form an effective water-blocking structure, preventing water from seeping in, avoiding short circuits or damage caused by moisture, improving protection performance, and extending the life of the whole machine.
[0043] The basic working principle of this utility model is as follows: When the mounting guide rail 5 is unlocked, the slider 45 moves downward, causing one end of the third movable rod 44 to move downward. Since the second movable rod 43 is hinged to the third movable rod 44, the first movable rod 42 and the second movable rod 43 rotate on the wall-mounted bracket 41. The end of the third movable rod 44 away from the wall-mounted bracket 41 moves outward, thereby causing the mounting guide rail 5 to rotate around the first movable rod 42, causing the mounting guide rail 5 to tilt to a set angle. The user inserts the mounting protrusion 14 into the mounting groove 51 along the tilting direction, completing the installation of the mounting guide rail 5. After the installation guide rail 5 is adjusted to be vertical, it is locked in position by the locking mechanism 6, and the locking rod 62 is engaged with the ratchet part 621. When unlocking, the locking rod 62 is pulled to release the engagement, so that the installation guide rail 5 can be rotated again, making it easy to remove the body 1 in the tilt direction and complete the disassembly operation. When working, ambient air is first drawn in through the air inlet 12 at the rear end of the body 1. The air enters the warm air chamber 13 inside the body 1. Driven by the fan assembly 2, the air passes through the heating element 3 and is heated. Then, the warm air is discharged through the air outlet 11 at the front end, delivering the heated air to the outside.
[0044] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
