[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0022] It should be noted that the terminology used herein is for the purpose of describing particular implementations only and is not intended to limit the exemplary implementations according to this utility model.

[0023] Example 1 like Figure 1 , Figure 2 As shown, this embodiment discloses an outdoor HVAC system with protective functions, including an outdoor HVAC unit 1, on which a protective mechanism is provided.

[0024] The protective mechanism includes a waterproof canopy 31, an adjusting rod 4, a water collection box 2, and a connecting rod 22. The adjusting rod 4 is located on both sides of the HVAC outdoor unit 1, at the upper end of the HVAC outdoor unit 1, and one end of the adjusting rod 4 is rotatably connected to the HVAC outdoor unit 1. One side of the waterproof canopy 31 is fixed to the lower side of the adjusting rod 4. The water collection box 2 is located on both sides of the HVAC outdoor unit 1, at the lower end of the HVAC outdoor unit 1.

[0025] In this embodiment, two water collection boxes 2 are provided, located on both sides of the HVAC outdoor unit 1. During rainy weather, the water collection boxes 2 will collect rainwater.

[0026] Specifically, ear plates 11 are fixedly installed on both sides of the bottom of the HVAC outdoor unit 1, and the water collection box 2 is placed above the ear plates 11 and connected to the ear plates 11 by at least two return springs 12. One end of the return spring 12 is fixedly connected to the upper part of the ear plate 11, and the other end is fixedly connected to the lower part of the water collection box 2. The inner side wall of the return spring 12 is provided with a damper 13 to buffer the impact force generated by the weight change of the water collection box 2, so that the protective mechanism operates more smoothly.

[0027] In this embodiment, the ear plate 11 provides a connection basis for the operation of the protective mechanism. Four return springs 12 are provided, two on one side. In the initial state, the return springs 12 are made of 65Mn carbon spring steel, which has a high elastic limit, low density, and light weight. The damper 13 is a miniature air damper, also low in density and light in weight. Together, the return springs 12 and damper 13 provide just enough support for the empty water collection box 2. After collecting rainwater, the weight of the water collection box 2 changes. During the water collection process, it compresses the return springs 12 and damper 13. After the water collection box 2 drains, the return springs 12 and damper 13 help it return to its original position, thereby causing the waterproof canopy 31 to return to its original position.

[0028] Specifically, such as Figure 4 As shown, one end of the adjusting rod 4 is rotatably connected to the HVAC outdoor unit 1 via a mounting shaft 14. The mounting shaft 14 is rotatably mounted on the HVAC outdoor unit 1, and its position is close to the outer edge of the HVAC outdoor unit 1, located above the water collection box 2. One end of the adjusting rod 4 is fixedly sleeved on the mounting shaft 14; a gear 41 is fixedly sleeved on the mounting shaft 14, and the gear 41 is fixedly connected to the adjusting rod 4.

[0029] In this embodiment, the adjusting rod 4, which is sleeved on the mounting shaft 14, is fixedly connected to the gear 41 on the side away from the HVAC outdoor unit 1. The rotation of the two adjusting rods 4 will gradually drive the waterproof canopy 31 into an unfolded state, thereby enabling the waterproof canopy 31 to automatically open and protect the HVAC outdoor unit 1 in rainy weather.

[0030] Specifically, a connecting rod 22 is fixedly installed on the side of the water collection box 2 near the HVAC outdoor unit 1, and a rack 23 is fixedly installed on the upper end of the connecting rod 22. The rack 23 is meshed with the gear 41 on the mounting shaft 14.

[0031] In this embodiment, the downward movement of the water collection box 2 will cause the connecting rod 22 to move downward, the downward movement of the connecting rod 22 will cause the rack 23 to move downward, the downward movement of the racks 23 on both sides will cause the gear 41 to rotate, the rotation of the gear 41 will cause the mounting shaft 14 to rotate, the rotation of the mounting shaft 14 will cause the adjusting rod 4 to rotate, thereby controlling the unfolding and folding of the waterproof canopy 31.

[0032] Specifically, a positioning rod 3 is fixedly installed below the two adjusting rods 4, and the other side of the waterproof canopy 31 is fixed to the upper side of the positioning rod 3, which plays a role in positioning and supporting the waterproof canopy 31.

[0033] A piston 21 is movably installed on the lower side of the water collection box 2. In sunny weather, the user can open the piston 21 to allow the water in the water collection box 2 to flow out, thereby resetting the device, and the waterproof cover 31 will fold back up.

[0034] In this embodiment, the waterproof canopy 31 unfolds in conjunction with components such as the water collection box 2 to cover and protect the HVAC outdoor unit 1, preventing direct contact with rainwater; when it is sunny or when no protection is needed, it can be folded up between the positioning rod 3 and the adjusting rod 4.

[0035] In this embodiment, the working principle of the protective mechanism of the outdoor HVAC system is as follows: The HVAC outdoor unit 1 is usually placed outdoors. When the outdoor environment is rainy, the HVAC outdoor unit 1 needs to be protected. Water collection boxes 2 are installed on both sides of the HVAC outdoor unit 1. In rainy weather, the water collection boxes 2 collect rainwater. After collecting the rainwater, the weight of the water collection box 2 changes, which compresses the return spring 12 and the damper 13. The water collection box 2 moves downward, which drives the connecting rod 22 to move downward. The connecting rod 22 moves downward, which drives the rack 23 to move downward. The racks 23 on both sides move downward, which drives the gear 41 to rotate. The rotation of the gear 41 drives the mounting shaft 14 to rotate. The rotation of the mounting shaft 14 drives the two adjusting rods 4 to rotate. The rotation of the two adjusting rods 4 gradually drives the waterproof canopy 31 to unfold. Thus, in rainy weather, the waterproof canopy 31 can automatically open to protect the HVAC outdoor unit 1. In sunny weather, the user can open the piston 21 to let the water in the water collection box 2 flow out, realize the reset of the equipment, and the waterproof canopy 31 will fold back up.

[0036] In excessively hot weather, users can also actively fill the water collection box 2 with water to open the waterproof canopy 31, which can provide auxiliary shading for the HVAC outdoor unit 1.

[0037] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
