Description

Technical Field

[0001] This utility model relates to the field of snowflake machine technology, and in particular to a snowflake machine that is easy to add and clean. Background Technology

[0002] A snow machine is a device used to artificially produce snowflake-like ice chips. It mainly uses a refrigeration system to rapidly freeze water or other liquids into ice layers at low temperatures, and then uses blades to scrape the ice layers into fine snowflake particles. Snow machines are characterized by fast ice-making speed, continuous ice production, and fine snowflake texture, and are widely used in catering, cold drink production, food preservation, and experimental demonstrations.

[0003] In existing snow ice machines, users need to open the feed box when cleaning it or adding beverages. When the feed box is connected to the outside, it causes pressure fluctuations inside the ice-making chamber, affecting the low-temperature effect of the evaporator. This results in reduced ice-making efficiency or uneven snow ice texture, and also poses a safety hazard. Utility Model Content

[0004] The purpose of this invention is to provide a snowflake machine that is easy to add and clean, allowing for cleaning of the feed box or quick addition of beverages without disassembling the entire machine, preventing accidental activation of the equipment during cleaning or adding, and ensuring safe use.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a snowflake machine that is easy to add and clean, comprising a machine body, an ice-making chamber therein, a snowflake preparation component inside the ice-making chamber, an ice outlet channel on one side of the ice-making chamber, a material box detachably mounted on the machine body, the material box having a slot at its upper end and communicating with the ice-making chamber at its lower end; a sliding cover is slidably mounted on the upper end of the material box, one end of the sliding cover having a first limiting wall extending downward; a micro switch is provided at the end of the material box near the first limiting wall, and a contact block for triggering the micro switch is provided on the first limiting wall; the micro switch is electrically connected to the snowflake preparation component and is used to control the on / off state of the snowflake preparation component; a snap-fit ​​structure is provided between the material box and the sliding cover, and when the sliding cover slides relative to the material box and closes in place, the sliding cover and the material box are positioned and engaged through the snap-fit ​​structure.

[0006] By adopting the above technical solution and setting a sliding cover that can be opened, users can easily add raw materials to the material box or clean the inside. When the sliding cover is opened, the first limit stop causes the contact block to disengage from the micro switch, thereby automatically cutting off the power supply to the snowflake preparation component and improving the safety of the equipment.

[0007] The present invention is further configured such that: a fixed cover is provided at the end of the material box away from the micro switch, and a second limiting wall extending downward is provided at the end of the sliding cover away from the first limiting wall, and the second limiting wall abuts against the fixed cover.

[0008] By adopting the above technical solution, by setting a fixed cover at the other end of the material box and setting a second limiting baffle at the end of the sliding cover, the sliding cover can form a closed state with the fixed cover when it slides to the closed position, while limiting the sliding stroke of the sliding cover and improving the structural stability.

[0009] The present invention is further configured such that: a first sealing strip is provided on the inner side of the first limiting wall, and a second sealing strip is provided on the outer side of the second limiting wall.

[0010] By adopting the above technical solution, the setting of the first sealing strip and the second sealing strip makes the connection between the sliding cover and the material box tighter, effectively preventing air from entering the material box and causing pressure changes inside the machine, thus ensuring the stability and safety of the shaved ice making process.

[0011] The present invention is further configured such that: one end of the material box is provided with an electrical connection cavity, the material box is provided with a male connector, the machine body is provided with a female connector corresponding to the male connector, and the male connector and the female connector are plugged into each other; the micro switch is electrically connected to the male connector through the electrical connection cavity, and the female connector is electrically connected to the electrical components inside the machine body.

[0012] By adopting the above technical solution, when the material box is installed on the machine body, the male and female connectors automatically plug in, realizing electrical connection between the micro switch and the internal electrical components of the machine body, thereby ensuring the normal operation of the snowflake preparation assembly; when the user needs to disassemble the material box for adding materials or cleaning, the male and female connectors immediately separate, automatically cutting off the circuit. The present invention is further configured such that: the outer wall of the material box is provided with an outer sliding groove arranged along the sliding direction of the sliding cover; the sliding cover is provided with an outer wing; the outer wing is connected to both ends of the first limiting wall and is perpendicular to the first limiting wall; the outer wing is provided with an outer sliding rail; and the outer sliding rail is slidably engaged with the outer sliding groove.

[0013] By adopting the above technical solution, the outer wing and the limiting baffle form a stable support structure, which enhances the overall strength of the sliding cover. The cooperation between the outer sliding groove and the outer sliding rail ensures that the sliding cover runs smoothly during opening and closing, and is not easy to shake or get stuck.

[0014] The present invention is further configured such that: the inner wall of the material box is provided with an inner sliding groove arranged along the sliding direction of the sliding cover; the sliding cover is provided with an inner wing; the inner wing is provided with an inner sliding rail; and the inner sliding rail is slidably engaged with the inner sliding groove.

[0015] By adopting the above technical solution, the cooperation between the inner slide rail and the inner slide groove enables the sliding cover to have the same guiding and supporting effect on the inner wall, achieving balanced sliding from both sides, and further improving sealing and stability.

[0016] The present invention is further configured such that: the outer slide rail is provided with an upwardly curved first outer hook, and the outer slide groove is provided with a downwardly curved second outer hook, the first hook and the second hook being tightly engaged; the inner slide rail is provided with an upwardly curved first inner hook, and the inner slide groove is provided with a downwardly curved second inner hook, the first hook and the second hook being tightly engaged.

[0017] By adopting the above technical solution, the sliding cover and the material box can be prevented from loosening or falling off during frequent operation, while the sealing of the side of the sliding cover is enhanced.

[0018] The present invention is further configured such that: the snap-fit ​​structure includes a buckle provided on the inner wing, and the inner wall of the material box is provided with a corresponding slot, and the buckle engages with the slot.

[0019] By adopting the above technical solution, the cooperation between the buckle and the slot facilitates the quick locking of the sliding cover in the closed state, preventing accidental sliding. The structure is simple and the operation is convenient.

[0020] The present invention is further configured such that: the sliding cover is provided with a lever part, and the lever part is provided with multiple protruding ribs.

[0021] By adopting the above technical solution, the lever part on the sliding cover is provided with raised ribs, which can enhance the friction of the fingers, making it easier and more slip-resistant for users to operate, thus improving the user experience.

[0022] The present invention is further configured such that: the snowflake preparation component includes a material tray disposed in the ice-making chamber, a blade fixed on the material tray, and an evaporator drum rotatably disposed in the ice-making chamber, wherein the blade tip is close to the evaporator drum.

[0023] By adopting the above technical solution, the snowflake preparation component adopts a structure in which an evaporator drum and a fixed blade are combined. After the liquid freezes on the outer wall of the evaporator, it is scraped by the blade to form snowflakes. It can efficiently prepare fine and uniform snowflake ice, and has a simple structure and stable operation.

[0038] The present invention will be further described below with reference to the accompanying drawings.

[0039] like Figures 1 to 5 As shown, this utility model provides a snowflake machine that is easy to add and clean. It includes a body 1 with an ice-making chamber 11 inside. The ice-making chamber 11 contains a snowflake preparation component 2. An ice outlet channel 12 is provided on one side of the ice-making chamber 11 to discharge the produced snowflakes from the body 1 for easy collection. A material box 3 is detachably installed on the body 1 to store the liquid raw materials to be made into ice. The upper end of the material box 3 has a slot 31 for easy addition of liquid or cleaning of the inside by the user. The lower end of the material box 3 communicates with the ice-making chamber 11, allowing the liquid to automatically flow into the ice-making chamber 11 to participate in the ice-making process. The material box 3 has a detachable structure, and a sliding cover 4 is slidably installed on the upper end of the material box 3. The sliding cover 4 can move back and forth along the sliding direction of the material box 3. When the sliding cover 4 is fully open... When fully closed, the cover 4 can cover the entire slot 31. When the cover 4 is opened, the slot 31 is exposed. One end of the cover 4 is provided with a downwardly extending first limiting wall 41. A micro switch 32 is installed at the end of the material box 3 near the first limiting wall 41. The micro switch 32 is electrically connected to the snowflake preparation assembly 2 and is used to control the start and stop of the snowflake preparation assembly 2. The first limiting wall 41 is provided with a contact 411. When the cover 4 is closed, the contact 411 is pressed against the micro switch 32, the circuit is connected, and the snowflake preparation assembly 2 can work normally. When the cover 4 is opened, the contact 411 is disengaged from the micro switch 32, the circuit is immediately disconnected, and the snowflake preparation assembly 2 stops running, thereby preventing the equipment from running during feeding or cleaning.

[0040] like Figure 1 and Figure 4As shown, one end of the material box 3 is provided with an electrical connection cavity 37, and the material box 3 is provided with a male connector 38. The machine body 1 is provided with a female connector 13 corresponding to the male connector 38. The male connector 38 and the female connector 13 are plugged in and mated. The micro switch 32 is electrically connected to the male connector 38 through the electrical connection cavity 37, and the female connector 13 is electrically connected to the electrical components inside the machine body 1. When the material box 3 is installed on the machine body 1, the male connector 38 and the female connector 13 are automatically plugged in, realizing the electrical connection between the micro switch 32 and the electrical components inside the machine body 1, thereby ensuring the normal operation of the snowflake preparation component 2. When the user disassembles the material box 3, the male connector 38 and the female connector 13 are immediately separated, and the circuit is automatically cut off.

[0041] like Figure 6 and Figure 7 As shown, a fixed cover 33 is provided at the end of the material box 3 away from the micro switch 32, and a second limiting wall 42 extending downward is provided at the end of the sliding cover 4 away from the first limiting wall 41. When the sliding cover 4 slides to the closed position, the second limiting wall 42 abuts against the fixed cover 33. To enhance the sealing performance, a first sealing strip 412 is provided on the inner side of the first limiting wall 41, and a second sealing strip 421 is provided on the outer side of the second limiting wall 42. When the sliding cover 4 is closed, the two sealing strips contact the upper end of the material box 3 respectively, forming a double sealing layer, which effectively prevents air from entering the interior of the material box 3, avoids pressure fluctuations in the ice-making chamber 11 from affecting the ice-making effect, and thus ensures the stable generation and safe operation of snow ice.

[0042] like Figure 3As shown, to achieve smooth sliding of the sliding cover 4, the outer wall of the material box 3 is provided with an outer sliding groove 34 along the sliding direction of the sliding cover 4. The sliding cover 4 has outer wings 43 on both sides, which are vertically connected to both ends of the first limiting baffle 41. An outer slide rail 431 is provided on the outer wings 43, and the outer slide rail 431 cooperates with the outer sliding groove 34 to ensure that the sliding cover 4 is externally guided and constrained during sliding, guaranteeing smooth sliding without shaking or tilting. The outer wings 43 also increase the overall rigidity of the sliding cover 4, preventing structural deformation caused by frequent opening and closing. In addition, the inner wall of the material box 3 is also provided with an inner sliding groove 35 along the sliding direction of the sliding cover 4. The sliding cover 4 has an inner wing 44 at a corresponding position, and an inner slide rail 441 is provided on the inner wing 44. The inner slide rail 441 and the inner sliding groove... The sliding cover 4 is guided and supported from the inside by a 35 sliding fit. Through the double sliding structure, the sliding cover 4 can maintain a stable movement trajectory when opening and closing, further improving the sealing effect and service life. To prevent the sliding cover 4 from detaching during sliding, the outer slide rail 431 is provided with an upwardly curved first outer hook 4311, and the outer slide groove 34 is provided with a downwardly curved second outer hook 341. The two hooks are tightly fitted together. Similarly, the inner slide rail 441 is provided with a first inner hook 4411, and the inner slide groove 35 is provided with a second inner hook 351. The two are also tightly fitted together. This structure can prevent the sliding cover 4 from being pulled out of the material box 3 by external force while ensuring smooth sliding, realizing the function of anti-detachment and limiting, and forming a further seal on the side.

[0043] like Figure 4 and Figure 5 As shown, a snap-fit ​​structure is provided between the material box 3 and the sliding cover 4. When the sliding cover 4 slides relative to the material box 3 and closes in place, the sliding cover 4 and the material box 3 are positioned and engaged by the snap-fit ​​structure. The snap-fit ​​structure includes a buckle 442 on the inner wing 44 of the sliding cover 4, and a corresponding slot 36 is provided on the inner wall of the material box 3. When the sliding cover 4 is fully closed, the buckle 442 automatically engages with the slot 36 to achieve quick locking and prevent the sliding cover 4 from being accidentally opened due to vibration or tilting. The operation is convenient and the structure is stable. To facilitate the user's opening and closing operation, the sliding cover 4 is provided with a lever part 45, which is provided with multiple protruding ribs 451. The user can easily push and pull the sliding cover 4 by holding the lever part 45. The protruding ribs 451 can increase the friction between the fingers and the sliding cover 4, making the operation more effortless and more slip-resistant. Even when the hands are wet, the opening and closing can still be smooth, improving the human-computer interaction experience.

[0044] like Figure 2As shown, the snowflake preparation component 2 includes a material tray 21 disposed in the ice-making chamber 11, a blade 22 fixed on the material tray 21, and an evaporator drum 23 rotatably installed in the ice-making chamber 11. In use, liquid raw materials flow from the material box 3 into the material tray 21 through the discharge channel. The evaporator drum 23 starts to rotate, and its surface temperature drops rapidly. After the liquid contacts the surface of the drum, it freezes into an ice layer. Then, the fixed blade 22 scrapes the ice layer into fine snowflake-like particles. This process can be carried out continuously, and the resulting snowflake ice is delicate, soft, and has a uniform texture.

[0045] like Figure 2 As shown, the bottom of the material box 3 is provided with a discharge pipe 46 that communicates with the ice-making chamber 11. A ball bearing 47 is installed inside the discharge pipe 46, and a retaining ring 48 that cooperates with the ball bearing 47 is provided on the discharge pipe 46 to limit the movement stroke of the ball bearing 47. A push rod 211 is provided on the material tray 21, and the upper end of the push rod 211 passes through the discharge pipe 46. When the material box 3 is installed on the machine body 1, the push rod 211 pushes the ball bearing 47 to open the discharge passage, and the liquid can flow out smoothly. When the material box 3 is disassembled, the ball bearing 47 falls back to the position of the retaining ring 48 under the action of gravity, automatically closing the discharge port to prevent liquid leakage.

[0046] The basic working principle of this utility model is as follows: In use, the operator first adds the beverage required for ice making through the slot 31 at the upper end of the material box 3. Then, the sliding cover 4 is pushed closed. Guided by the outer slide rail 431 and the outer slide groove 34, and the inner slide rail 441 and the inner slide groove 35, the sliding cover 4 slides smoothly. The first limiting wall 41 and the second limiting wall 42 respectively form a sealing fit with the fixed cover 33. When the sliding cover 4 is completely closed, the contact block 411 on it will press down the micro switch 32, which connects the circuit, and the snowflake preparation component 2 starts working. At this time, the ice-making process begins. The evaporator drum 23 inside the ice cavity 11 begins to rotate and cool. The liquid on the material tray 21 gradually freezes on the surface of the evaporator drum 23 to form an ice layer. The blade 22 rotates with the material tray 21 to scrape the frozen ice layer into fine snowflake particles. The snowflakes are discharged through the ice outlet channel 12. When cleaning is required, the operator can push the sliding cover 4 open in the opposite direction. The first limit baffle 41 disengages from the micro switch 32, disconnecting the circuit and stopping the operation of the snowflake preparation component 2. Subsequently, the operator can directly clean and add materials to the interior through the slot 31 at the top without disassembly.

[0047] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
