Description

Technical Field

[0001] This utility model relates to the technical field of stage equipment, and in particular to a snow machine. Background Technology

[0002] A snow machine, also known as a snowmaking machine, is a device that simulates snowfall. It is widely used in events, wedding decorations, film shoots, shopping mall decorations, and other occasions requiring a romantic or dreamy atmosphere. The basic principle of a snow machine is that after the machine is plugged in, a strong airflow generated by high pressure transforms a special snow-snow oil liquid into snowflake-like foam. This foam is light and airy, and can remain suspended in the air for a period of time, thus simulating snowfall.

[0003] However, many current snow machines use a straight-through tubular design for their snow outlet, a design that has revealed several problems in practical use. Specifically, because the snow outlet is a straight-through tubular structure, when the snow machine is working, the snow oil is sprayed out under the action of high-pressure airflow, but some snow oil may remain inside the snow outlet. Over time, this residual snow oil may flow back along the pipe to the blower in the snow outlet due to factors such as gravity, airflow disturbance, or machine vibration. The blower is one of the key components of the snow machine; it is responsible for generating high-pressure airflow to push the snow oil to form snow foam and spray it out. If the blower is contaminated by the backflow of snow oil, it may cause a short circuit in the electrical components inside the blower, leading to a burn-out malfunction. This malfunction not only affects the normal operation of the snow machine but may also pose a safety hazard to the surrounding environment. Utility Model Content

[0004] In order to overcome the defects of the existing technology, this utility model proposes a snow machine that can solve the problem that the snow outlet of the current snow machine is a straight tubular structure, which makes it easy for the snow oil remaining in the snow outlet to flow back to the fan in the snow outlet, causing the fan to be easily short-circuited and burn out.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] The present invention provides a snow machine, including a snow outlet section. The snow outlet section has a bent structure and is divided into a blowing section, a bent section and a snow outlet section. The blowing section, the bent section and the snow outlet section are connected in sequence. An oil outlet is provided in the snow outlet section and a fan is provided in the blowing section. The air blown by the fan passes through the blowing section, the bent section and the snow outlet section to blow out snowflakes.

[0007] The preferred technical solution of this utility model is that the bending angle of the bending section is 70-110 degrees.

[0008] The preferred technical solution of this utility model is that the snow outlet part includes a bending head, an intermediate connector and a snow outlet head, the bending head, the intermediate connector and the snow outlet head are connected by threads in sequence, the air blowing section and the bending section are located at the bending head, the snow outlet section is located at the intermediate connector and the snow outlet head, and the oil outlet is located at the intermediate connector.

[0009] The preferred technical solution of this utility model is that an oil outlet pipe and a vent are provided on the intermediate connector; both the oil outlet pipe and the vent are connected to the bending head and the snow outlet head, and the oil outlet is located on the oil outlet pipe.

[0010] The preferred technical solution of this utility model is that the vents are arranged symmetrically around the oil outlet pipe.

[0011] The preferred technical solution of this utility model is that a mesh bag is attached to the oil outlet pipe.

[0012] The preferred technical solution of this utility model is that an annular groove is also provided on the oil outlet pipe.

[0013] A preferred embodiment of this invention is that the intermediate connecting member is further provided with an anti-slip part.

[0014] The preferred technical solution of this utility model is that the outlet of the snow discharge section has a sawtooth ring structure.

[0015] The preferred technical solution of this utility model is that the number of serrations in the serrated ring structure is 12-17.

[0016] The beneficial effects of this utility model are:

[0017] This invention proposes a snow-discharging machine that cleverly divides the snow-discharging section into three sequentially connected parts: a blowing section, a bending section, and a snow-discharging section. This effectively separates the blower from the snow-discharging oil return path. The blower, located in the blowing section, generates airflow that flows smoothly through the blowing section and the bending section before reaching the snow-discharging section and discharging the snowflakes. Importantly, the bending section not only optimizes the airflow direction but also creates a natural barrier, effectively preventing any residual snow-discharging oil in the snow-discharging section from flowing back to the blower. This avoids snow-discharging oil accumulation and backflow into the blower, fundamentally eliminating the risk of the blower burning out due to a short circuit caused by snow-discharging oil.

[0027] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] Example 1

[0029] This embodiment provides a snowflake machine, such as Figure 1-6As shown, to facilitate the display of the snow machine's structure, the internal wiring and piping connections are omitted. The snow machine includes a casing 5 and a base 7. The casing 5 is assembled from a top cover 51, a handle 52, a bottom cover 53, a front cover 54, and a rear cover 55. Inside the casing 5 are core components such as a snow outlet section, a blower 4, and an oil pump 6. The snow outlet section has a bent structure, divided into a blowing section, a bent section, and a snow outlet section. One end of the snow outlet section extends through the casing to the outside. The blowing section, bent section, and snow outlet section are connected sequentially. The oil pump pumps snow oil from the outside into the snow outlet section, which has an oil outlet 23. The blower 4 is located in the blowing section. The air blown by the blower passes through the blowing section, bent section, and snow outlet section, dispersing the snow oil and forming snowflakes. Specifically, by designing the snow outlet section as a bent structure, cleverly dividing it into three sequentially connected parts—the blowing section, the bent section, and the snow outlet section—effective separation of the blower and the snow oil return path is achieved. In this structure, the blower is located in the blowing section, responsible for generating airflow. The airflow smoothly passes through the blowing section and the bending section, finally reaching the snow outlet section and blowing out the snowflakes. Importantly, the design of the bending section not only optimizes the airflow guidance but also forms a natural barrier, effectively preventing any residual snowflake oil in the snow outlet section from flowing back to the blower. This avoids the accumulation of snowflake oil and its return to the blower, fundamentally eliminating the risk of the blower burning out due to a short circuit caused by snowflake oil. Therefore, this technical solution, through the bending structure design of the snow outlet section and the rational configuration of the oil outlet, creatively solves a key problem in the use of snow machines, improving the stability and safety of the equipment.

[0030] Preferably, the bending angle of the bending section is 70-110 degrees. The selection of 70-110 degrees as the preferred bending angle is based on in-depth research and precise calculations of the internal fluid dynamics characteristics of the snow machine. This angle range not only effectively prevents snowflake oil from flowing back from the snow outlet section to the fan, but also optimizes the guidance and uniformity of the airflow, ensuring that the air blown by the fan can pass smoothly and efficiently through the bending section, reducing energy loss. Furthermore, the 70-110 degree bending angle also considers the overall compactness and aesthetics of the snow machine, enabling the equipment to maintain high performance while also possessing a good appearance design and space utilization. This angle range not only improves the operating efficiency and stability of the snow machine but also takes into account the user experience and ease of equipment maintenance. In this embodiment, the bending angle of the bending section is 90 degrees.

[0031] For ease of assembly, the snow-discharging section preferably includes a bending head 1, an intermediate connector 2, and a snow-discharging head 3. The bending head 1, intermediate connector 2, and snow-discharging head 3 are sequentially threaded together. The air-blowing section and the bending section are located at the bending head 1, the snow-discharging section is located at the intermediate connector 2 and the snow-discharging head 3, and the oil outlet 23 is located at the intermediate connector 2. This design, which breaks down the snow-discharging section into a bending head, intermediate connector, and snow-discharging head for easy processing and assembly, and then combines them via threaded connections, significantly improves the maintainability and scalability of the snow machine. The threaded connections not only ensure a tight fit and stability between the components but also allow for easy disassembly and reinstallation when maintenance or replacement is needed, reducing maintenance costs and time. Furthermore, this modular design allows the snow machine to be flexibly configured and upgraded according to actual needs, such as adjusting the angle of the bending section or replacing the snow-discharging head with a different size, to adapt to different usage scenarios and customer requirements. Therefore, this preferred technical solution has significant advantages and practicality in improving the performance of the snow machine and the user experience.

[0032] Preferably, the intermediate connector 2 is provided with an oil outlet pipe 21 and a vent 22; both the oil outlet pipe 21 and the vent 22 are connected to the bend head 1 and the snow outlet head 3, and the oil outlet 23 is located on the oil outlet pipe 21. Specifically, the bend head 1 has an oil inlet 11, and the oil delivery hose passes through the oil inlet 11 and the oil outlet 23 to deliver snowflake oil into the oil outlet pipe. The design of providing an oil outlet pipe and a vent on the intermediate connector, connecting the bend head and the snow outlet head, further optimizes the internal structure and fluid management of the snow machine. The oil outlet pipe ensures that the snowflake oil can be smoothly discharged when needed, avoiding accumulation inside the equipment and the risk of short circuits; while the vent ensures unobstructed airflow, ensuring that the air blown by the fan can efficiently pass through the entire snow outlet section, evenly blowing out the snowflakes. The oil outlet being located on the oil outlet pipe not only facilitates the collection and discharge of snowflake oil but also makes the oil discharge process more controllable and stable. This technical solution not only improves the operating efficiency and safety of snow machines, but also provides users with a more convenient and reliable user experience.

[0033] Preferably, the vents 22 are centrally symmetrically arranged around the oil outlet pipe 21. This centrally symmetrical layout ensures that the airflow remains evenly distributed as it passes through the vents, avoiding situations where the local wind speed is too high or too low, thereby improving the snow discharge effect and stability of the snow machine. Simultaneously, this layout also helps reduce turbulence and eddies in the airflow around the oil outlet pipe, reducing energy loss and noise generation. Furthermore, this relative positional relationship between the vents and the oil outlet pipe helps maintain the continuity of airflow during oil discharge, preventing airflow interruptions or instability caused by oil discharge.

[0034] Preferably, a mesh bag 24 is fitted onto the oil outlet pipe 21. The mesh bag 24 is designed to allow the flowing snowflake oil to pass through the mesh bag under the influence of wind, forming smaller droplets, thus making the final snowflakes more delicate and beautiful. In this embodiment, a cloth mesh bag is used. Furthermore, an annular groove 25 is also provided on the oil outlet pipe 21. The mesh bag 24 is fitted into the annular groove 25 and secured with cable ties to prevent the mesh bag from detaching from the oil outlet pipe due to strong winds.

[0035] Preferably, the intermediate connector 2 is further provided with an anti-slip part 26. The anti-slip part facilitates the installation of the intermediate connector and makes it easier for users to install and disassemble.

[0036] Preferably, the outlet 31 of the snow-exit section has a serrated annular structure. This structure not only enhances the strength and stability of the snow-exit section but also significantly improves the snow-exit effect and the uniformity of snowflake distribution. The serrated annular structure of the outlet can more effectively cut and disperse snowflakes, making the snowflakes more delicate and uniform when sprayed. At the same time, the serrated annular structure can also increase the contact area between snowflakes and air, improving the suspension effect and visual appeal of the snowflakes. Furthermore, the number of serrations in the serrated annular structure is 12-17. Through in-depth research and experimental verification by the inventors, setting the number of serrations within the range of 12-17 ensures that the snowflakes are fully dispersed and refined when sprayed, while maintaining a certain amount of snowflakes and a certain snow-exit speed, thereby meeting the user's basic requirements for snowflake effects. At the same time, the design of 12-17 serrations can also effectively avoid the problems caused by too many or too few serrations. Too many serrations may result in snowflakes that are too fine and fragmented, affecting the visual effect; while too few serrations may result in uneven snowflake distribution or poor snow-exit.
