Description

Technical Field

[0001] This application relates to the technical field of snowflake machines, and more specifically, to a snowflake machine that is easy to add liquid. Background Technology

[0002] A snowflake machine is a device that freezes water or other liquids through a refrigeration system and shaves them into snowflake-shaped ice cream. It is widely used in places such as cold drink shops and dessert shops.

[0003] During the operation of a snow flake machine, it is necessary to continuously replenish the liquid in the container to ensure uninterrupted production of shaved ice. Current technologies present several inconveniences with the container filling methods. For example, some machines have the container located deep inside the equipment, requiring the entire machine to be moved or part of the outer casing removed for filling, making the operation extremely cumbersome. Other machines use a top-filling method, which is prone to spillage due to operator error, polluting the surrounding environment and making precise control of the filling amount difficult. Furthermore, some existing snow flake machines have inadequate container sealing structures, leading to leakage during operation, affecting normal equipment function and wasting liquid.

[0004] In addition, some existing snow flake machines feature a detachable material tank structure on its side. In this structure, the material tank is installed on the side of the snow flake machine via a threaded or snap-fit ​​connection. The bottom of the tank has a discharge port, which connects to the material box inside the snow flake machine via a pipe. When refilling is required, the operator must first remove the material tank from the side of the snow flake machine, then take it outside for refilling, and finally reinstall it on the snow flake machine. The connection between the material tank and the pipe is typically sealed using rubber sealing rings and ball bearings.

[0005] The aforementioned snow flake machine requires the material hopper to be removed from the machine and taken outside for filling, a process that is quite cumbersome and consumes a significant amount of the operator's time and energy. Especially during peak usage periods, frequent disassembly and assembly operations can severely impact the efficiency of the snow flake machine, thereby affecting the user experience.

[0006] On the other hand, although the aforementioned snowflake machine uses rubber sealing rings and ball bearings for sealing, during long-term use, the ball bearings may wobble, or the rubber sealing rings may be worn, aged, or corroded by the liquid, leading to a decrease in sealing performance and leakage. Once leakage occurs, not only will the liquid be wasted, but the leaked liquid will also drip onto the snowflake machine, requiring frequent cleaning.

[0007] The applicant also noted that existing snow flake machines lack effective liquid level control devices, forcing operators to rely on observation of the markings on the feed tank or experience to determine if the liquid level is full. This method makes precise liquid level control difficult, easily leading to overfilling and overflow, or underfilling and disrupting the continuous operation of the snow flake machine. Utility Model Content

[0008] To solve or improve the above-mentioned problems existing in the prior art, this application provides a snowflake machine that is easy to add liquid, the structure of which specifically includes a snowflake machine body, a water tank assembly, an injection pipe, a material box, and a float sealing assembly;

[0009] The water tank assembly is detachably installed on the top of the snow machine body, including the water tank body and an automatic sealing device located at the discharge port of the water tank body. When not installed on the snow machine body, the automatic sealing device seals the discharge port.

[0010] The filling pipe is at least partially located inside the snow machine body. The first end of the filling pipe can be connected to the discharge port of the water tank body and enable the automatic sealing device to open the discharge port. The second end of the filling pipe is connected to the float sealing assembly.

[0011] The material box is located inside the main body of the snowflake machine;

[0012] The float sealing assembly is located inside the material box and includes a float and a liquid outlet. The float can rise or fall with the liquid level in the material box, thereby sealing or opening the liquid outlet.

[0013] In the aforementioned design, the water tank's discharge port is equipped with an automatic sealing device, which can tightly seal when not filled, effectively preventing liquid leakage. Furthermore, the material box and float sealing assembly work together to achieve precise control of the liquid level within the material box, ensuring that the liquid level is always maintained within the set range. Whether producing small quantities of shaved ice or supplying large quantities, this guarantees a sufficient supply of liquid without overfilling, underfilling, or leakage.

[0014] Optionally, a panel is also included, which is detachably mounted on the snow machine body;

[0015] With the panel removed, at least the material box inside the snow machine body can be exposed.

[0016] Optionally, at least a portion of the panel may be made of a transparent material, or the panel may have an observation window.

[0017] Optionally, the panel covers at least a portion of the top of the snow machine body and at least a portion of the side of the snow machine body facing the operator;

[0018] The panel is connected to the snow machine body via a magnetic or sliding fastener structure.

[0019] Optionally, the panel is equipped with a handle structure.

[0020] In the aforementioned solution, an operation panel is installed on the front of the snow machine, connected by magnetic attraction or sliding fasteners. The operation panel is made of a transparent material (such as plexiglass) or has an observation window, allowing the operator to observe the internal filling process without opening the panel. The operation panel has hand rests for easy opening and closing. When cleaning is required, the operator simply pulls open the operation panel to expose the interior for rinsing and cleaning.

[0021] Optionally, the automatic sealing device includes a sealing plug and a spring;

[0022] The sealing plug has at least one communicating groove that connects the lower end face and the side face of the sealing plug;

[0023] The sealing plug is connected to the main body of the water tank by a spring and can move axially within the discharge port based on the elastic deformation of the spring;

[0024] When the water tank assembly is not installed on the main body of the snow machine, the connecting groove is closed by the inner wall of the discharge port so that the sealing plug seals the discharge port.

[0025] In the aforementioned scheme, the sealing plug is reset by a spring, which makes the automatic sealing device more reliable and less prone to leakage after long-term use.

[0026] Optionally, a tubular structure is provided on the inner side of the first end of the filling pipe;

[0027] When the water tank assembly is installed on the main body of the snow machine, the tubular structure can contact the lower end face of the sealing plug and drive the sealing plug to move toward the inside of the water tank body until the connecting groove on the side of the sealing plug is exposed inside the water tank body, so that the sealing plug can open the feed port.

[0028] In the aforementioned scheme, the tubular structure can cooperate with the sealing plug. When the water tank assembly is installed on the snow machine body, the tubular structure can lift the sealing plug, so that the connecting groove on the side of the sealing plug is exposed inside the water tank body. At this time, the connecting groove on the sealing plug can connect the filling pipe and the inside of the water tank body, so that the discharge port is open.

[0029] Optionally, the float sealing assembly also includes:

[0030] The sealing assembly body has an internal pipe. One end of the pipe is connected to the second end of the filling pipe, and the other end is connected to the liquid outlet. The opening direction of the liquid outlet is vertically downward.

[0031] The float arm is located below the liquid outlet, with one end connected to the float and the other end connected to the sealing assembly body via a rotating shaft;

[0032] A sealing plug is located on the upper side of the float arm;

[0033] When the liquid level in the hopper rises, the float drives the float arm to rotate, causing the sealing plug to move toward the outlet and seal the outlet; when the liquid level in the hopper falls, the float drives the float arm to rotate, causing the sealing plug to move away from the outlet and open the outlet.

[0034] Optionally, the float seal assembly can be detachably connected to the second end of the filling pipe.

[0035] Optional, a variety of replaceable float seal assemblies are available to suit different feed liquids or different types of product formulations.

[0036] Optionally, a sealing bushing is provided at the connection point between the float sealing assembly and the second end of the filling pipe. This is suitable for alternative float sealing assemblies and is used to ensure a seal between the float sealing assembly and the filling pipe after installation.

[0037] Optionally, the float sealing assembly includes:

[0038] A wireless liquid level sensor is connected to a float and then to a control terminal via a wireless signal.

[0039] An electric valve, installed at the liquid outlet, can close or open the liquid outlet based on liquid level data provided by a wireless liquid level sensor or instructions from a control terminal.

[0040] In the aforementioned solution, liquid level data can be transmitted wirelessly to a remote control terminal (such as a mobile app or computer software). Operators can view the liquid level in the material box anytime, anywhere via the remote control terminal and remotely control the electric valve installed on the filling pipeline to perform the filling operation. This solution can further improve the convenience of operation, especially for large chain stores or places that need to centrally manage multiple snow flake machines. Managers can use a single control terminal to uniformly monitor and manage the liquid filling status of all snow flake machines.

[0041] Optional, including:

[0042] Gravity sensor, located at the bottom of the material box;

[0043] A mechanical valve is installed at the liquid outlet and connected to a gravity sensor via a transmission structure. When the weight of the material box is greater than or less than a threshold, the liquid outlet is either sealed or opened.

[0044] The aforementioned solution has a relatively simple structure, low cost, and does not require complex electronic control modules or additional power supplies.

[0045] In summary, the snowflake machine provided in this embodiment is convenient and efficient for adding liquid, has good sealing properties to prevent leakage, and can accurately control the liquid level. Furthermore, it features a detachable panel that allows for easy observation of the internal liquid level, facilitating internal rinsing and cleaning. Attached Figure Description

[0062] In this specification, it will also be understood that when a component is referred to as being "connected to" other components relative to them, such as "connected to" other components, the component may be directly connected to or directly coupled to the component, or there may be an intervening third component; in addition, in the embodiments of this application, "connection" mainly refers to mechanical structural connections or pipeline connections that form fluid communication.

[0063] This application will now be described more fully below with reference to the accompanying drawings. However, this application can be implemented in many different ways and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided herein to make this application more detailed and complete, and to fully convey the scope of this application to those skilled in the art. The same reference numerals denote the same objects throughout the drawings.

[0064] In order to solve or improve the problems existing in the prior art, the embodiments of this application aim to provide a structure of a snow machine, more specifically, the structure of the filling system in the snow machine, which can realize convenient, efficient and accurate filling of liquid from the front of the snow machine, while solving problems existing in the prior art such as inconvenient filling, easy leakage, uncontrollable liquid level and inconvenient cleaning, thereby improving the user experience and operational stability of the snow machine.

[0065] To achieve the aforementioned objectives, the technical concept of this application embodiment is to install an openable and closable water tank on the top of the snowflake machine. The water tank's discharge port is equipped with an automatic sealing component. When the water tank is connected to or separated from the filling pipe, the automatic sealing component is in an open / closed state. The other end of the filling pipe is connected to a float sealing component, which is placed inside the material box. The liquid flows from the water tank into the material box through the filling pipe. When the liquid level in the material box rises to a preset height, the float rises, and the filling pipe closes to prevent liquid leakage, thereby achieving automated control of the filling process.

[0066] In a specific embodiment, the provided snowflake machine, which facilitates the addition of liquid filling, has the following external structure: Figure 1 As shown, the snow machine body 100 includes a material box 200 mounted on the top of the snow machine body 100, and a panel 600 is also provided on the front of the snow machine body 100.

[0067] Figure 2 To show the exploded view of the internal structure of the snow machine, such as Figure 2As shown, it also includes a filling pipe 300, a material box 400, and a float sealing assembly 500.

[0068] in,

[0069] The water tank assembly 200 is detachably installed on the top of the snow machine body 100, including the water tank body 210 and an automatic sealing device 220 provided at the discharge port of the water tank body. When not installed on the snow machine body 100, the automatic sealing device 220 seals the discharge port. The water tank assembly 200 serves as an initial container for storing the liquid materials (such as water, syrup, etc.) required for the snow machine to make snowflakes.

[0070] The filling pipe 300 is at least partially located inside the snow machine body 100. The first end of the filling pipe 300 can be connected to the discharge port of the water tank body and enable the automatic sealing device 220 to open the discharge port. The second end of the filling pipe 300 is connected to the float sealing assembly 500. The filling pipe 300 is responsible for transporting the liquid from the water tank assembly 200 to the material box 400. For example, it includes components such as pipes, joints, and sealing silicone. Its design must meet the requirements of smooth liquid transportation and sealing.

[0071] The material box 400 is located inside the main body 100 of the snowflake machine. It serves as a container for storing the liquid materials (such as water, syrup, etc.) required for making snowflakes by the quantitative snowflake machine and for placing the float sealing assembly 500. It is one of the key components for the operation of the snowflake machine, and its liquid storage capacity directly affects the working efficiency and stability of the snowflake machine.

[0072] The float sealing assembly 500 is installed inside the material box 400 and includes a float 510 and a liquid outlet 520. The float 510 can rise or fall with the liquid level in the material box 400, thereby sealing or opening the liquid outlet 520. The float sealing assembly 500 controls the opening and closing of the liquid entering the material box by the height change of the float 510 (related to the liquid level change). When the liquid level in the material box does not reach the preset height, the float sinks and the liquid in the water tank is injected normally through the filling pipe. When the liquid level in the material box rises to the preset height, the float rises and the liquid outlet 520 closes, stopping the injection.

[0073] In the aforementioned embodiments, the side-filling method of the prior art is broken through, and the operation panel and the filling pipeline system are integrated on the front and top of the snow machine, which improves the convenience of filling operation. This is one of the key points that distinguishes this application from the prior art, enabling operators to complete the filling work without moving equipment or removing a large number of parts, thus improving the user experience.

[0074] It should be understood that the snow machine body 100 in the embodiments of this application is provided with the necessary components for the operation of the snow machine, such as a refrigeration device, a stirring or planing device, a power supply, and a control module. These devices and modules are similar to those in the prior art and are not the focus of this application. Due to space limitations, this application will not elaborate on them.

[0075] In an optional embodiment, a top cover is also included, which is used to close the first end opening of the filling pipe 300 after the water tank assembly 200 is separated from the snow machine body 100.

[0076] In a preferred embodiment, a panel 600 is also included, which is detachably disposed on the snow machine body 100; when the panel 600 is detached, at least the material box 400 inside the snow machine body 100 can be exposed.

[0077] In a preferred embodiment, at least a portion of the panel 600 is made of a transparent material, or the panel is provided with an observation window 610. In an alternative embodiment, at least a portion of the panel 600, or the observation window, is made of plexiglass.

[0078] In a preferred embodiment, panel 600 covers at least a portion of the top of snow machine body 100 and at least a portion of the side of snow machine body 100 facing the operator; panel 600 is connected to snow machine body 100 by a magnetic or sliding structure.

[0079] In the aforementioned embodiment, after the panel 600 is removed, the inside of the equipment can be maintained or cleaned from the front of the snow machine body 100, that is, from the side facing the operator.

[0080] In a preferred embodiment, the panel 600 is also provided with a handle (not shown in the figure) that is easy to detach and install.

[0081] In the aforementioned embodiments, the panel 600 can be used to operate the machine functions. It is designed to be removable and modular, making it easy for users to clean the inside of the machine.

[0082] In a preferred embodiment, the top of the water tank body 210 is provided with an openable dust cover (not shown in the figure).

[0083] In a typical embodiment, the automatic sealing device 220 is installed on the water tank body 210 as follows: Figure 7 As shown;

[0084] like Figure 8 As shown, the automatic sealing device 220 includes a sealing plug 221 and a spring 222.

[0085] The sealing plug 221 has at least one communicating groove 223, which connects the lower end face (i.e. the left end face of the sealing plug 221 in the figure) and the side face.

[0086] The sealing plug 221 is connected to the water tank body 210 by a spring 222 and can move axially within the discharge port based on the elastic deformation of the spring 222.

[0087] When the water tank assembly 200 is not installed on the snow machine body 100, due to the force applied by the spring 222, the sealing plug 221 is reset to the inner wall of the discharge port of the connecting groove 223, so that the sealing plug 221 seals the discharge port.

[0088] In a typical embodiment, the cross-section of the connecting groove 223 is fan-shaped, with one end penetrating the lower end face of the sealing plug 221 and at least partially penetrating the sidewall of the sealing plug 221.

[0089] In a typical embodiment, the sealing plug 221 is a variable-diameter cylinder, with the diameter of the lower end face portion being larger than the diameter of the other portions.

[0090] In a typical embodiment, there are four connecting grooves 223. In this embodiment, the lower end face of the sealing plug 221 has a circular cross-sectional shape and includes four fan-shaped holes, while the portion above the lower end face of the sealing plug 221 has a cross-shaped cross-section.

[0091] In a typical embodiment, a sealing structure such as a sealing ring or an O-ring is provided around the sealing plug 221. The specific form of the sealing structure is no different from that of the prior art. Due to space limitations, it will not be described in detail in the embodiments of this application.

[0092] In a typical embodiment, such as Figure 8 As shown, spring 222 is a cylindrical spring, which is fitted on the outside of the part above the lower end face of sealing plug 221. One end is connected to the lower end face of sealing plug 221, and the other end is connected to the water tank body 210.

[0093] Although the foregoing embodiments show that... Figure 8 The automatic sealing device 220 is an example, but this application is not limited to this. The automatic sealing device 220 in this application can be other types of structures, as long as it can seal the discharge port when the water tank assembly 200 is detached from the snow machine body 100, and open the discharge port and the filling pipe 300 when the water tank assembly 200 is installed on the snow machine body 100.

[0094] The aforementioned automatic sealing device 220 effectively solves the problem of leakage that easily occurs in the sealing structure of the prior art. This automatic sealing design not only improves the reliability of the equipment, but also reduces a series of negative impacts caused by leakage, such as material waste and frequent cleaning.

[0095] In an optional embodiment, a guide sleeve is also provided between the sealing plug 221 and the discharge port.

[0096] In a preferred embodiment, such as Figure 6 As shown, a tubular structure 310 is provided on the inner side of the first end (upper end in the figure) of the filling pipe 300. Typically, the tubular structure 310 is connected to the inner wall of the first end of the filling pipe 300 by four rib structures.

[0097] In a typical embodiment, such as Figure 6 As shown, two fixing structures are symmetrically arranged on the outer side of the first end of the filling pipe 300 for fixing the filling pipe 300 to the snow machine body 100.

[0098] In a typical embodiment, a sealing structure, such as a sealing ring, is provided at the connection between the first end of the filling pipe 300 and the water tank assembly 200.

[0099] When the water tank assembly 200 is installed on the snow machine body 100, the tubular structure 310 can contact the lower end face of the sealing plug 221 and drive the sealing plug 221 to move toward the inside of the water tank body 210 until the connecting groove 223 on the side of the sealing plug 221 is exposed inside the water tank body 210. In this state, the liquid inside the water tank body 210 can pass through the connecting groove 223 on the side of the sealing plug 221 and flow through the lower end face of the sealing plug 221 to the inside of the filling pipe 300. In other words, the sealing plug 221, which is pushed by the tubular structure 310, opens the discharge port.

[0100] When the water tank assembly 200 separates from the snow machine body 100, the tubular structure 310 disengages from the lower end face of the sealing plug 221. Under the action of the elastic force of the spring 222, the sealing plug 221 moves away from the interior of the water tank body 210 and resets. The opening of the connecting groove 223 on the side of the sealing plug 221 is resealed by the inner wall of the discharge port, so that the discharge port is resealed.

[0101] In an optional embodiment, the water tank body 210 is made of high-strength plastic or stainless steel, giving it good corrosion resistance and sealing performance.

[0102] In a typical embodiment, such as Figure 6 As shown, the opening direction of the first end of the filling pipe 300 is longitudinal; the opening direction of the second end of the filling pipe 300 is transverse and is located inside the material box 400.

[0103] like Figure 5 As shown, in addition to the float 510 and liquid outlet 520 described in the aforementioned embodiments, the float sealing assembly 500 further includes:

[0104] The sealing assembly body 530 serves as the basic structure of the float sealing assembly 500. It has a pipe inside, one end of which is connected to the second end of the filling pipe 300, and the other end is connected to the liquid outlet 520. The opening direction of the liquid outlet 520 is vertically downward.

[0105] Preferably, the sealing assembly body 530 is connected to the second end of the filling pipe 300 via a sealing quick-release connector.

[0106] The float arm 540 is located below the liquid outlet 520, with one end connected to the float 510 and the other end connected to the sealing assembly body 530 via a rotating shaft 550; typically, the rotating shaft 550 is arranged in a horizontal direction.

[0107] A sealing plug 560 is located on the upper side of the float arm 540. Correspondingly, the liquid outlet 520 can also be provided with a sealing structure corresponding to the sealing plug 560, which can cooperate with the sealing plug 560 to achieve sealing and conduction of the liquid outlet 520.

[0108] When the liquid level in the material box 400 rises, the float 510 drives the float arm 540 to rotate (the direction of rotation is...). Figure 5 The clockwise rotation of the valve causes the sealing plug 560 to move toward the outlet 520 and seal the outlet 520; when the liquid level in the material box 400 drops, the float 510 drives the float arm 540 to rotate (rotation direction is...). Figure 5 (Counterclockwise) causes the sealing plug 560 to move away from the liquid outlet 520 and open the liquid outlet 520.

[0109] In an optional embodiment, the float sealing assembly 500 is detachably connected to the second end of the filling pipe 300.

[0110] The float sealing assembly 500 in the aforementioned embodiments enables precise control of the liquid level in the feed box, preventing liquid overflow. Furthermore, by controlling the liquid level in the feed box, the contact distance between the liquid and the refrigeration evaporator is effectively controlled, thereby improving the ice-producing efficiency and stability of the snow machine.

[0111] In a typical embodiment, the float 510 is a square buoyancy body with a density less than that of the liquid used in the snow machine. It can be a hollow box-shaped structure or made of low-density materials such as foaming materials.

[0112] Preferably, the system includes a variety of replaceable float sealing assemblies to suit different feed liquids or different types of product formulations. The float dimensions, density, and outlet size can vary among the different specifications of the float sealing assemblies.

[0113] Preferably, a sealing bushing is provided at the connection point between the float sealing assembly and the second end of the filling pipe, which is suitable for a replaceable float sealing assembly. The sealing bushing is used to ensure the sealing effect between the float sealing assembly and the filling pipe after the float sealing assembly is installed.

[0114] In an optional embodiment, the float sealing assembly 500 includes:

[0115] A wireless liquid level sensor is connected to the float 510 and to the control terminal via a wireless signal; an electric valve is installed at the liquid outlet 520 and can close or open the liquid outlet 520 according to the liquid level data provided by the wireless liquid level sensor or the instructions of the control terminal.

[0116] Typically, the aforementioned control terminals include mobile phones with control apps or computers with control software installed.

[0117] In the aforementioned optional embodiments, operators can view the liquid level in the material box anytime, anywhere via a remote control terminal and remotely control the electric valve installed on the filling pipeline for filling operations. This solution can further improve operational convenience, especially for large chain stores or locations requiring centralized management of multiple snowflake machines. Managers can use a single control terminal to uniformly monitor and manage the liquid filling status of all snowflake machines. However, this solution may suffer from signal interference issues, requiring the selection of a reliable wireless communication module and the setting of a reasonable signal transmission frequency. Furthermore, the development and maintenance costs of the remote control terminal are relatively high.

[0118] In an optional embodiment, the snow machine includes:

[0119] A gravity sensor is located at the bottom of the material box 400;

[0120] A mechanical valve is installed at the liquid outlet 520 and is connected to a gravity sensor through a transmission structure. When the weight of the material box 400 is greater than or less than a threshold, the liquid outlet 520 is sealed or opened.

[0121] In the aforementioned optional embodiment, the gravity sensor determines the liquid level by detecting changes in the weight of the liquid in the container. When the liquid weight falls below a set value, a mechanical control device is triggered to open a mechanical valve installed on the filling pipeline for filling. The mechanical valve can be a rotary valve or ball valve similar to a faucet, connected to the gravity sensing trigger device via a mechanical linkage. This solution is relatively simple and low-cost, requiring no complex electronic control modules or power supply. However, the accuracy of the gravity sensor may be relatively low, and the mechanical control device may wear down during long-term use, affecting the accuracy and reliability of control, necessitating regular maintenance and calibration.

[0122] In summary, the snow machine provided in this application has the following advantages or beneficial technical effects:

[0123] Convenient and efficient filling: By incorporating an openable water tank and an integrated filling pipeline system on top of the snowflake machine, operators no longer need to disassemble the material bucket and take it outside for filling. The entire filling process can be completed from the front of the snowflake machine, significantly saving filling time and labor costs. For example, under the same material replacement or filling conditions, using the snowflake machine of this application for filling operations takes only about 30 seconds per operation, which is several times more efficient than existing technologies. This better meets the needs of businesses for rapid production of shaved ice and improves customer satisfaction.

[0124] Excellent sealing performance reduces the risk of leakage: The automatic sealing component at the filling port of the material box is specially designed to provide a tight seal when not filled, effectively preventing material leakage. Even during long-term use, the sealing performance remains reliable due to the high-quality elastic material used in the sealing plug and the excellent elastic recovery performance of the spring. Furthermore, the entire filling pipeline system uses sealed joints, further reducing the risk of leakage. Actual testing showed that the snow flake machine provided by this application did not experience any leakage after 1000 hours of continuous operation, while existing snow flake machines experienced an average of more than 5 leaks within the same operating time. This significantly reduces material waste and equipment failure repair costs caused by leakage.

[0125] Precise Liquid Level Control: The container capacity design, combined with the float assembly, enables precise control of the liquid level within the container. The float utilizes buoyancy variations to accurately control the opening and closing of the filling pipe, ensuring the liquid level in the container remains within the set range. Whether producing small quantities of shaved ice or supplying large quantities, it guarantees an ample supply of liquid without overfilling, underfilling, or leakage.

[0126] The control panel is detachable for easy cleaning: A control panel connected to the front of the snow machine via magnetic attraction or sliding fasteners is provided. The control panel is made of transparent material (such as plexiglass) or has an observation window, allowing the operator to observe the internal filling process without opening the panel. The control panel has a hand rest for easy opening and closing. When cleaning is required, the operator simply pulls open the control panel to expose the interior for rinsing and cleaning.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the embodiments of this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
