Technical Field

[0001] The invention relates to the technical field of ventilation equipment, and in particular to a telescopic circular diffuser for an animal room. Background Art

[0002] Diffusers are commonly used ventilation equipment in air-conditioning systems or rooms. In the current diffuser structure, a part of the diffusers are provided with a series of annular air guide covers in the pipe outlet, and the airflow flowing out from the inside of the air supply port is dispersed into multiple air outlet directions in a small area by the action of the annular air guide covers, thereby achieving dispersed blowing at the air supply port; another part of the diffusers adopts a non-dividing structure. Since there is no diversion structure to block it, the airflow flowing out from the inside of the air supply port blows directly vertically downward.

[0003] The current diffusers have the following disadvantages when in use: the spacing between the air guide covers is fixed and cannot be adjusted, which makes it impossible to adjust the ventilation volume and airflow size; secondly, dust and other dirt easily adhere to the surface of the air guide covers, affecting the ventilation effect and requiring manual regular cleaning. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a telescopic circular diffuser for an animal room. By connecting a plurality of guide covers that can move up and down in an annular shell, the spatial size of the guide channel can be adjusted, aiming to solve the problems in the background technology.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Embodiment: This embodiment discloses a telescopic circular diffuser for an animal room, such as Figure 1-Figure 7 As shown, it includes: an annular shell 1, which is provided with multiple mounting holes. The annular shell 1 is fixedly installed on the top of the animal room. A plurality of trumpet-shaped air deflectors 2 of different sizes are arranged in the annular shell 1. The diameter of the air deflector 2 close to the center of the annular shell 1 is smaller, and the diameter of the air deflector 2 away from the center of the annular shell 1 is larger; the air deflector 2 can move up and down in the annular shell 1, and a guide channel 3 is formed between adjacent air deflectors 2, and air flows through the guide channel 3; and a lifting seat 4 is connected in the annular shell 1 for driving each air deflector 2 to move up and down; wherein, a cleaning mechanism 5 for cleaning the inner surface of the air deflector 2 is connected below the annular shell 1 to prevent dust and dirt from adhering to the surface of the air deflector 2.

[0025] Preferably, Figure 4 As shown, the diameter of the air guide cover 2 gradually increases from top to bottom, and a first air outlet 21 and a second air outlet 22 are respectively provided at both ends of the air guide cover 2. The diameter of the first air outlet 21 is greater than the diameter of the second air outlet 22, and the first air outlet 21 of the inner air guide cover 2 is the same size as the second air outlet 22 of the outer air guide cover 2, so that the inner air guide cover 2 can be completely retracted into the outer air guide cover 2.

[0026] Among them, a fixing frame 10 is fixedly connected to the annular shell 1, a lifting motor 8 is fixedly installed on the fixing frame 10, a screw rod 9 is connected to the rotating shaft of the lifting motor 8, and the screw rod 9 is threadedly connected to the lifting seat 4; a plurality of rotating rods 6 are rotatably connected in the annular shell 1, and the rotating rods 6 are evenly distributed along the circumference of the annular shell 1; a pull rod 7 is hinged between the rotating rod 6 and the air deflector 2; when the rotating rod 6 rotates, it can drive the air deflector 2 to rise and fall.

[0027] like Figure 5-Figure 6 As shown, the lifting seat 4 is provided with a plurality of slide grooves 42, in which a plurality of sliders 41 are slidably connected, one end of the rotating rod 6 is hinged to the inner wall of the annular shell 1, and the other end is hinged to the slider 41; when the lifting seat 4 is lifted or lowered, the slider 41 slides in the slide groove 42, driving the rotating rod 6 to rotate, and when the rotating rod 6 rotates, it can drive each air guide cover 2 to lift or lower. Since the rotating trajectory of the rotating rod 6 is in an arc shape, the lifting distance of the air guide cover 2 close to the center of the annular shell 1 is larger, and the lifting distance of the air guide cover 2 far from the center of the annular shell 1 is smaller, so that the lifting distances of each air guide cover 2 are different, thereby being able to change the size of the guide channel 3 and adjust the ventilation volume of the animal room.

[0028] like Figure 7 As shown, the cleaning mechanism 5 includes a slide 51 capable of circular motion along the annular housing 1, the annular housing 1 is fixedly connected to an annular guide rail 12, the annular guide rail 12 is fixedly connected to a gear ring 11, the slide 51 is slidably connected to the annular guide rail 12, and a drive motor 52 is fixedly installed on the slide 51, a gear 53 meshing with the gear ring 11 is connected to the rotating shaft of the drive motor 52, the gear 53 is driven to rotate by the drive motor 52, and then the slide 51 is driven to slide in a circle on the annular guide rail 12, a bracket 54 is fixedly connected to the slide 51, a brush holder 55 is rotatably connected to the bracket 54, and a roller brush 56 is rotatably connected to the brush holder 55; a roller 57 is coaxially connected to the roller brush 56, and the roller 57 drives the roller brush 56 to rotate when the roller 57 rolls. The lifting seat 4 is movable, and one end of the brush holder 55 is rotatably connected to the connecting rod 13. The surface of the lifting seat 4 is provided with an annular groove 43, and a connecting block 44 is slidably connected to the annular groove 43. The connecting block 44 is rotatably connected to the connecting rod 13. When the lifting seat 4 is lifted and lowered, the brush holder 55 is driven to rotate. When the lifting seat 4 rises to the top, the roller brush 56 contacts the inner surface of the air deflector 2. When the roller brush 56 rotates, the inner surface of the air deflector 2 is cleaned; when the sliding seat 51 slides on the annular guide rail 12, it drives the connecting block 44 to slide in the annular groove 43; when the lifting seat 4 is lifted and lowered to the top position, each air deflector 2 is driven to rise, and the lower end of the inner air deflector 2 rises to the upper end of the outer air deflector 2, so that the inner surface of the air deflector 2 is almost on the same conical surface. Figure 3As shown, when the lifting seat 4 rises, it drives the brush frame 55 to rotate to an inclined upward state, so that the roller brush 56 contacts the inner surface of each air deflector 2, and the roller 57 contacts the inner surface of the outermost air deflector 2. The driving motor 52 drives the slide 51 to slide on the annular guide rail 12. During the sliding process, the roller 57 rotates to drive the roller brush 56 to rotate, thereby comprehensively cleaning the inner surface of the air deflector 2 and cleaning away the dust and dirt on the inner surface of the air deflector 2.

[0029] Working principle: the lifting motor 8 drives the lifting seat 4 to lift, and the lifting seat 4 drives the rotating rod 6 to rotate. When the rotating rod 6 rotates, it can drive each deflector 2 to lift. The greater the lifting distance of the deflector 2 close to the center of the annular shell 1, the smaller the lifting distance of the deflector 2 away from the center of the annular shell 1, so that the lifting distance of each deflector 2 is different, and then the size of the guide channel 3 can be changed to adjust the ventilation volume of the animal room; when it is necessary to clean the surface of the deflector 2, the lifting seat 4 is lifted to the top position, driving each deflector 2 rises, so that the inner surfaces of the air deflector 2 are almost on the same conical surface. At the same time, when the lifting seat 4 rises, it drives the brush frame 55 to rotate to an inclined upward state, so that the roller brush 56 contacts the inner surface of each air deflector 2, and the roller 57 contacts the inner surface of the outermost air deflector 2. The driving motor 52 drives the slide seat 51 to slide on the annular guide rail 12. During the sliding process, the roller 57 rotates to drive the roller brush 56 to rotate, thereby comprehensively cleaning the inner surface of the air deflector 2 and cleaning away the dust and dirt on the inner surface of the air deflector 2.
