[0002] HVAC refers to the system or related equipment responsible for heating, ventilation and air conditioning indoors or in a car. The design of the HVAC system applies thermodynamics, fluid mechanics and fluid machinery. It is an important branch of mechanical engineering. The HVAC system can control the temperature and humidity of the air and improve indoor comfort. It is an important part of medium and large industrial buildings or office buildings.

[0027] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example 1

[0029] A preferred embodiment of the air volume regulating device for HVAC provided by the utility model is as follows: Figures 1 to 5 As shown: an air volume regulating device for HVAC, comprising an air conditioning equipment body 1, an adjusting mechanism 2 is arranged on the side of the air conditioning equipment body 1, an air outlet 3 is opened on the surface of the air conditioning equipment body 1, a fan blade plate 4 is rotatably connected to the inner wall of the air outlet 3, a display screen 5 is arranged on the surface of the air conditioning equipment body 1 above the air outlet 3, a connecting line 6 is arranged on the bottom of the air conditioning equipment body 1, and a mounting plate 7 is fixedly connected to the back of the air conditioning equipment body 1.

[0030] In this embodiment, the air outlet 3 and the fan blade plates 4 are provided in three groups, and the three groups of fan blade plates 4 are arranged in an arc shape. Because the three groups of fan blade plates 4 are arranged in an arc shape, when the user removes the filter, the fan blade plates 4 will not get caught on the user's skin.

[0031] In this embodiment, a rectangular groove is provided on the back of the mounting plate 7, and the air-conditioning device body 1 is installed on the wall through the mounting plate 7. Because a rectangular groove is provided on the back of the mounting plate 7, the air-conditioning device body 1 can be prevented from directly contacting the wall, so that a gap is left between the air-conditioning device body 1 and the wall, thereby improving the heat dissipation effect of the air-conditioning device body 1.

[0032] Example 2

[0033] Based on Example 1, a preferred embodiment of an air volume regulating device for HVAC provided by the utility model is as follows: Figures 1 to 5 As shown: the adjustment mechanism 2 includes an electric push rod 21, a rack 22, a gear 23, a rotating plate 24, a sliding column 25, a lifting plate 26, an adjustment plate 27 and a limit column 28. The side of the air-conditioning equipment body 1 is fixedly connected with the electric push rod 21, the output end of the electric push rod 21 is fixedly connected with the rack 22, the bottom of the rack 22 is meshed with the gear 23, the side of the gear 23 is fixedly connected with the rotating plate 24, the side of the rotating plate 24 is fixedly connected with the sliding column 25, the surface of the sliding column 25 is attached with the lifting plate 26, the side of the lifting plate 26 is fixedly connected with the adjustment plate 27, and the back of the adjustment plate 27 is fixedly connected with the limit column 28.

[0034] In this embodiment, the sliding distance of the rack 22 is half the circumference of the gear 23, and the rack 22 can drive the gear 23 to rotate 180° at most. When the air volume needs to be reduced, the electric push rod 21 can be controlled to drive the rack 22 to slide backward. Because a group of gears 23 are meshed with the rack 22, when the rack 22 slides, it will drive a group of gears 23 to rotate counterclockwise.

[0035] In this embodiment, there are two groups of gears 23, which are meshed with each other. The rotating plate 24 is located at the center of the gears 23. Since the two groups of gears 23 are meshed with each other, when one group of gears 23 rotates counterclockwise, it will drive the other group of gears 23 to rotate clockwise. At this time, the rotating plate 24 fixedly connected to the other group of gears 23 will rotate clockwise accordingly.

[0036] In this embodiment, a transversely arranged sliding groove is opened on the side of the lifting plate 26, and the sliding column 25 is embedded in the transverse groove on the side of the lifting plate 26. Because the sliding column 25 is fixedly connected to the rotating plate 24, when the rotating plate 24 rotates, it will drive the sliding column 25 to slide backward in the sliding groove of the lifting plate 26, and the lifting plate 26 will drop accordingly.

[0037] In this embodiment, two groups of limit columns 28 are provided, and two groups of vertically arranged slide grooves are opened on the surface of the air-conditioning equipment main body 1. The two groups of limit columns 28 are respectively embedded in the two groups of vertical grooves on the surface of the air-conditioning equipment main body 1. Because the adjustment plate 27 is fixedly connected to the lifting plate 26, when the lifting plate 26 descends, the adjustment plate 27 will be driven to descend together. At this time, the two groups of limit columns 28 fixedly connected to the adjustment plate 27 will slide downward in the two groups of vertical grooves on the surface of the air-conditioning equipment main body 1, and play a certain limiting role on the lifting plate 26, so that the adjustment plate 27 descends vertically.

[0038] In this embodiment, the adjustment plate 27 is transparent, and the corners of the adjustment plate 27 are arc-shaped. Because the adjustment plate 27 is transparent, the adjustment plate 27 will not block the display screen 5 from receiving the signal of the remote control.

[0039] Working principle and use process of the utility model: First, the air conditioner main body 1 is installed on the wall through the mounting plate 7. Because the mounting plate 7 has a rectangular groove on the back, the air conditioner main body 1 can be prevented from directly contacting the wall, so that a gap is left between the air conditioner main body 1 and the wall, thereby improving the heat dissipation effect of the air conditioner main body 1;

[0040] When the air volume needs to be reduced, the electric push rod 21 can be controlled to drive the rack 22 to slide backward. Because a set of gears 23 are meshed with the rack 22, when the rack 22 slides, it will drive a set of gears 23 to rotate counterclockwise. Since the two sets of gears 23 are meshed with each other, when one set of gears 23 rotates counterclockwise, it will drive the other set of gears 23 to rotate clockwise. At this time, the rotating plate 24 fixedly connected to the other set of gears 23 will rotate clockwise accordingly. Because the sliding column 25 is fixedly connected to the rotating plate 24, when the rotating plate 24 rotates, it will drive the sliding column 25 on the lifting plate 26, the lifting plate 26 will slide backward in the slide groove, and the lifting plate 26 will drop accordingly. Because the adjusting plate 27 is fixedly connected to the lifting plate 26, when the lifting plate 26 drops, the adjusting plate 27 will be driven to drop together. At this time, the two groups of limiting columns 28 fixedly connected to the adjusting plate 27 will slide downward in the two groups of vertical grooves on the surface of the air-conditioning equipment body 1, and play a certain limiting role on the lifting plate 26, so that the adjusting plate 27 drops vertically. When the adjusting plate 27 drops to cover the air outlet 3, the air volume can be reduced, and the hot air can be prevented from blowing directly on people to protect people's skin.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
