Description

Technical Field

[0001] This utility model relates to the field of snowmaking equipment technology, specifically to a whirlwind snow machine. Background Technology

[0002] The whirlwind snow machine is a common snowmaking device, mainly used in stage performances, film and television shooting, etc. Its principle is to pump snow oil to the nozzle to atomize it into simulated snowflakes, and then use a fan to generate airflow to send the simulated snowflakes into the air.

[0003] Existing snow machines generally use a long straight cylinder with an axial fan and nozzle inside, making them quite heavy. Adjusting the snow spray angle requires manual rotation, which is inconvenient. An existing patent (CN219589221U) describes a high-efficiency spray snowmaking device that uses an electric push rod for adjustment. While this solution is convenient, it requires additional electric push rods and corresponding control chips, resulting in a higher overall cost. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a whirlwind snow machine, which makes adjustment more labor-saving through the setting of the movable cover.

[0005] The technical solution adopted in this utility model is as follows: A cyclone snow machine includes a centrifugal fan, the outlet of which is connected to an upwardly angled fixed pipe, a limiting frame on the outer shell of the centrifugal fan, a movable cover hinged to the fixed pipe, the movable cover having an opening, a nozzle being installed inside the movable cover, and a locking mechanism being provided between the movable cover and the limiting frame. The movable cover can be rotated in a vertical plane to adjust the orientation of the opening and is locked in place by a locking mechanism.

[0006] Compared with the prior art, the beneficial effects of this utility model are as follows: By using centrifugal fans, which have higher air pressure than axial fans, the spraying effect can be guaranteed. The traditional long tube can be replaced with a fixed pipe and a smaller movable hood. When adjusting, only the movable hood and nozzle need to be lifted, which is lighter and therefore easier to adjust.

[0007] In a preferred embodiment of this utility model, a hinge is provided on the upper part of the fixed tube, and the upper part of the movable cover is connected to the fixed tube through the hinge.

[0008] Beneficial effects: Compared with the traditional long cylindrical structure, the movable cover of this solution can be installed using hinges, which have the advantages of easy installation and good support.

[0009] In a preferred embodiment of this utility model, the lower part of the fixed tube is provided with an arc-shaped surface, and during adjustment, the lower part of the movable cover rotates along the arc-shaped surface.

[0010] Beneficial effects: By setting the curved surface, the curved surface is always in contact with the movable cover, ensuring a certain degree of airtightness and making the airflow less likely to disperse.

[0011] In a preferred embodiment of this utility model, the limiting frame includes two side plates, and the movable cover is located between the two side plates and rotates along the inner side of the side plates.

[0012] Beneficial effects: The two side plates installed on the centrifugal fan casing limit the left and right directions of the movable cover and ensure a certain degree of sealing.

[0013] In a preferred embodiment of this utility model, the locking mechanism includes a threaded rod with a knob at its outer end, a threaded hole on the side wall of the movable cover, an arc-shaped hole on the side plate, and the inner end of the threaded rod passing through the arc-shaped hole and the threaded hole in sequence.

[0014] Beneficial effects: Due to its lighter weight compared to traditional long cylindrical tubes, it can be locked by turning the knob and threaded rod when the knob is pressed tightly against the side wall.

[0015] In a preferred embodiment of the present invention, the limiting frame further includes a receiving groove, the two sides of which are connected to corresponding side plates by bolts, and an oil storage tank is provided in the receiving groove, which is connected to the nozzle pipe.

[0016] Beneficial effects: By setting up a receiving tank, the oil storage tank is integrated into the device, making it more convenient to move the equipment.

[0017] In a preferred embodiment of this utility model, the receiving trough is located above the centrifugal fan.

[0018] Beneficial effects: The above settings result in a more compact overall structure and a smaller footprint. Attached Figure Description

Detailed Implementation

[0021] Typical embodiments embodying the features and advantages of this utility model will be specifically described in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0022] In the description of this application, the terms "first", "second", etc. are used only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the structure referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0023] See Figures 1 to 3 As shown, this embodiment discloses a cyclone snow machine, including a centrifugal fan 1, a fixed pipe 2, a movable cover 3, a nozzle 4, a limiting frame 5, and a locking mechanism 6.

[0024] The fixed pipe 2 is installed obliquely upward on the centrifugal fan 1 by bolts. The lower part of the fixed pipe 2 is provided with an arc-shaped surface 22, and the upper part of the fixed pipe 2 is provided with a hinge 21. The upper part of the movable cover 3 is connected to the fixed pipe 2 by the hinge 21, and the lower part of the movable cover 3 rotates along the arc-shaped surface 22.

[0025] The limiting frame 5 includes two side plates 51, and the movable cover 3 is located between the two side plates 51 and rotates along the inner side of the side plates 51. The limiting frame 5 also includes a receiving groove 53, which is located above the centrifugal fan 1. The two sides of the receiving groove 53 are connected to the corresponding side plates 51 by bolts. The locking mechanism 6 includes a threaded rod 61, and a knob 62 is provided at the outer end of the threaded rod 61. The side wall of the movable cover 3 is provided with a threaded hole, and the side plate 51 is provided with an arc-shaped hole 52. The inner end of the threaded rod 61 passes through the arc-shaped hole 52 and the threaded hole in sequence.

[0026] The limiting frame 5 also includes a receiving groove 53, in which an oil storage tank 7 is provided. The oil storage tank 7 is connected to the nozzle 4 via a pipe. The nozzle 4 is equipped with a pump body and an oil inlet hole 41 on its outer wall, which can draw snowflake oil from the oil storage tank 7.

[0027] The limiting frame 5 is provided with a mounting plate 8 on the side away from the movable cover 3. The mounting plate 8 can be used to install a control panel for controlling the wind force of the centrifugal fan 1.

[0028] The working principle and method of this embodiment are as follows: When the angle needs to be adjusted, turn the knob 62 outward so that the movable cover 3 is in a rotatable state. After rotating the movable cover 3, turn the knob 62 inward. When the knob 62 is tightly against the side wall, it can be locked. By setting the receiving slot 53 above the centrifugal fan 1, the overall structure is more compact and occupies less space; Centrifugal fan 1 can generate greater wind pressure, ensuring a better snow spray range and height.
