Description
Technical Field
[0001] This utility model relates to the field of snowflake machine technology, and in particular to a snowflake machine with a magnetic protection structure. Background Technology
[0002] Snowflake ice makers work by having a beverage adhere to the surface of a rotating ice-making drum. The drum's own cooling capacity then rapidly freezes the beverage, creating a thin layer of ice. When the drum rotates to the scraper position, the scraper removes the ice, thus producing snowflake ice. Existing snowflake ice makers typically consist of a main body and a beverage container, usually integrated. The container has a drain pipe at the bottom for supplying beverages to the main body, making filling difficult. Other existing technologies use a separate beverage container, typically consisting of a storage tank and a top cap. However, if the operator forgets to close the top cap after filling the storage tank, the pressure inside will remain constant with atmospheric pressure, causing the liquid level to drop rapidly and spill. This issue urgently needs improvement. Utility Model Content
[0003] The purpose of this invention is to provide a snow machine with a magnetic protection structure, which can prevent the top cover from being forgotten to be placed on the top of the liquid storage box and effectively improve the operational safety of the snow machine during use.
[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A snow machine with a magnetic protection structure includes a snow machine body and a liquid container. The snow machine body has an ice outlet channel and an installation cavity connected to the ice outlet channel. The liquid container is installed on the top of the snow machine body through the installation cavity. An ice-making drum and an ice scraper are provided between the installation cavity and the ice outlet channel. The ice scraper is used to scrape the thin ice prepared on the surface of the ice-making drum to the ice outlet channel. The liquid container includes a liquid storage box and a top cover. The top cover is detachably installed on the liquid storage box. When the top cover is placed on the liquid storage box, a liquid storage cavity is formed between the top cover and the liquid storage box. The liquid storage box has a drain pipe at its bottom, a ball bearing inside the drain pipe, a sealing sleeve at the open end of the drain pipe, and a drain hole axially opened in the sealing sleeve, which communicates with the cavity of the drain pipe. The snow machine body has a lifting top rod corresponding to the drain pipe, a magnet on the top cover, and a magnetic control component corresponding to the magnet on the snow machine body. The snow machine body has a drive device electrically connected to the magnetic control component. When the liquid storage box is inserted into the mounting cavity and the top cover is placed on the liquid storage box, the magnetic control component and the magnet engage in a sensing interaction, and the drive device drives the top rod to rise, pushing the ball bearing and the sealing sleeve to separate, thus opening the lower end of the drain pipe.
[0005] By adopting the above technical solution, the operator can remove the liquid container from the snow machine body. At this time, the magnetic control component senses that the magnet is moving away and drives the top cover to descend via the drive device, removing the top cover from the liquid storage box. Beverages or water are then added to the liquid storage box. At this time, the sealing sleeve of the drain pipe opening is blocked by the ball bearing. After the liquid is replenished, the operator places the liquid storage box into the mounting cavity of the snow machine body. If the operator forgets to close the top cover, the magnetic control component cannot detect the magnet's position, the drive device will not drive the push rod to move upward, and the ball bearing will always be in a sealed fit with the sealing sleeve. The drain pipe will not discharge water, and the ice outlet channel of the snow machine will not dispense snowflakes. When the top cover is placed on the liquid storage box, the magnetic control component detects that the magnet is in position and controls the drive device to lift the top rod. The top rod lifts the ball and moves it away from the sealing sleeve, thus opening the lower end of the drain pipe and allowing water to flow. This prevents the liquid level from dropping rapidly if the top cover is not placed on the liquid storage box, thereby improving the operational safety of the product. It effectively prevents the top cover from being left on the top of the liquid storage box and improves the operational safety of the snow machine.
[0006] A further feature of this invention is that the top cover has a rectangular structure, and at least one magnet is fixed at each of the four right-angle positions of the top cover. An iron block is fixed at the top of the liquid storage box corresponding to the magnet. The magnet and the iron block are attracted and cooperate to seal the top cover onto the liquid storage box.
[0007] By adopting the above technical solution, the magnetic attraction between the magnet and the iron block can be used to make the top cover fit tightly on the top of the liquid storage box, improving the sealing connection between the top cover and the liquid storage box. In addition, the magnets set in multiple corners ensure that the magnetic control component can detect the position of the magnets when the top cover is fitted onto the liquid storage box at any angle, thereby controlling the top rod to lift up.
[0008] A further feature of this invention is that a first sealing ring is embedded at the bottom edge of the top cover, and the top cover and the liquid storage box are sealed together by the first sealing ring, with the iron block distributed on the outside of the first sealing ring.
[0009] By adopting the above technical solution, the first sealing ring can improve the sealing performance between the top cover and the liquid storage box.
[0010] A further feature of this invention is that the magnetic sensing control assembly includes a magnetic sensor and a control board electrically connected to the magnetic sensor, the magnetic sensor engaging with the magnet, and the output terminal of the control board being electrically connected to the driving device.
[0011] By adopting the above technical solution, the magnetic sensor will capture the position of the magnet, thereby detecting whether the top cover is installed in place on the liquid storage box. When the magnetic sensor detects that the top cover is removed from the liquid storage box, it will control the drive device to run through the control board and pull the top rod down. When the magnetic sensor detects that the top cover is installed in place, it will control the drive device to run through the control board and push the top rod up.
[0012] A further feature of this invention is that the snow machine body has a vertically extending lifting channel at the bottom of the mounting cavity, the top rod is slidably disposed in the lifting channel, and the driving device drives the top rod to move up and down in the lifting channel.
[0013] By adopting the above technical solution, the addition of the lifting channel can improve the consistency of the vertical sliding direction of the top rod within the snow machine body.
[0014] A further feature of this invention is that a plurality of second sealing rings are fixedly sleeved on the top rod, and the top rod and the lifting channel are sealed together by the second sealing rings.
[0015] By adopting the above technical solution, the second sealing ring can prevent leakage between the top rod and the lifting channel due to small gaps when the top rod slides up and down in the lifting channel.
[0016] A further feature of this invention is that the driving device is an electric cylinder, and the end of the push rod of the electric cylinder is fixedly connected to the bottom of the push rod.
[0017] A further feature of this invention is that the driving device consists of a driving motor and a driving gear, the driving motor drives the driving gear to rotate, the bottom of the top rod is integrally provided with a rack portion, the rack portion is slidably disposed in the lifting channel, and the driving gear meshes with the rack portion for transmission.
[0018] A further feature of this invention is that the inner wall of the drain pipe is provided with a plurality of blocks that cooperate with the ball stop, and the ball is constrained and movably disposed in the drain pipe cavity between the block and the sealing sleeve.
[0019] By adopting the above technical solution, the baffle can prevent the ball bearing from separating from the drain pipe when the liquid container is inverted.
[0020] A further feature of this invention is that the end edge of the sealing sleeve has an arc-shaped contact surface corresponding to the ball, and the ball is sealed and fitted to the end face of the sealing sleeve through the arc-shaped contact surface.
[0021] By adopting the above technical solution, the arc-shaped mating surface can increase the contact area between the ball and the upper end face of the sealing sleeve, thereby improving the sealing performance of the ball to the end of the sealing sleeve.
[0022] In summary, this utility model has the following beneficial effects: The system employs a magnet mounted on the top cover, and a magnetic control component and a drive device electrically connected to the magnetic control component are mounted on the main body of the snow machine. The drive device moves the top rod up and down, allowing the operator to remove the liquid container from the main body of the snow machine. At this point, the magnetic control component senses the magnet moving away and, via the drive device, lowers the top cover, removing it from the liquid storage box. Beverages or water are then added to the storage box. The sealing sleeve of the drain pipe opening is blocked by ball bearings. After refilling, the operator places the storage box back into the mounting cavity of the snow machine. If the operator forgets to close the top cover, the magnetic control component cannot detect the magnet's position. The drive unit does not cause the push rod to move upward, and the ball bearings remain in a sealed fit with the sealing sleeve. Water will not flow from the drain pipe, and snowflakes will not exit the ice outlet channel of the snow machine body. When the top cover is placed on the liquid storage box, the magnetic control component detects the magnet's position and controls the drive unit to lift the push rod, causing it to push the ball bearings upward and away from the sealing sleeve. This opens the lower end of the drain pipe, allowing water to flow. This prevents the liquid level from dropping rapidly if the top cover is left on the liquid storage box, thus improving operational safety during product use. It effectively prevents situations where the top cover is left on the liquid storage box and significantly enhances the operational safety of the snow machine. Attached Figure Description

[0029] The present invention will be further described below with reference to the accompanying drawings. Specific Implementation Example 1 A snowflake machine with a magnetic protection structure, such as Figures 1-4As shown, the device includes a snow machine body 1 and a liquid container 2. The snow machine body 1 has an ice outlet channel 11 and an installation cavity 12 connected to the ice outlet channel 11. The liquid container 2 is installed on the top of the snow machine body 1 through the installation cavity 12. An ice-making drum 13 and an ice scraper 14 are provided between the installation cavity 12 and the ice outlet channel 11. The ice scraper 14 is used to scrape the thin ice prepared on the surface of the ice-making drum 13 into the ice outlet channel 11. The liquid container 2 includes a liquid storage box 3 and a top cover 4. The top cover 4 is detachably installed on the liquid storage box 3. When the top cover 4 is placed on the liquid storage box 3, a liquid storage chamber 21 is formed between the top cover 4 and the liquid storage box 3; the bottom of the liquid storage box 3 is provided with a drain pipe 31, the drain pipe 31 is provided with a ball bearing 32, the open end of the drain pipe 31 is provided with a sealing sleeve 33, the sealing sleeve 33 is axially provided with a drain hole 331, the drain hole 331 is connected to the cavity of the drain pipe 31, the snow machine body 1 is provided with a lifting rod 6 corresponding to the drain pipe 31, the top cover 4 is provided with a magnet 41, and the snow machine body 1 is provided with a magnetic control group corresponding to the magnet 41. Component 5: The snow machine body 1 is equipped with a drive device electrically connected to the magnetic induction control component 5. When the liquid storage box 3 is inserted into the mounting cavity 12 and the top cover 4 is placed on the liquid storage box 3, the magnetic induction control component 5 and the magnet 41 are inductively engaged, and the drive device drives the top rod 6 to rise upward, pushing the ball 32 to separate from the sealing sleeve 33, so that the lower end opening of the drain pipe 31 is open; the inner wall of the drain pipe 31 is provided with several stops 311 that cooperate with the stops of the ball 32, and the ball 32 is constrained and movably disposed on the stops 311. In the drain pipe 31 cavity between 11 and sealing sleeve 33, the stop block 311 can prevent the ball 32 from separating from the drain pipe 31 when the liquid container 2 is inverted; the end edge of the sealing sleeve 33 is provided with an arc-shaped contact surface 332 corresponding to the ball 32, and the ball 32 is sealed and fitted with the end face of the sealing sleeve 33 through the arc-shaped contact surface 332. The arc-shaped contact surface 332 can increase the contact area between the ball 32 and the upper end face of the sealing sleeve 33, thereby improving the sealing performance of the ball 32 to the end of the sealing sleeve 33.
[0031] like Figures 2-4The top cover 4 shown is rectangular in shape. At least one magnet 41 is fixed at each of the four right-angle positions of the top cover 4. An iron block 34 is fixed to the top of the liquid storage box 3 corresponding to the magnet 41. The magnet 41 and the iron block 34 attract and cooperate, allowing the top cover 4 to seal tightly onto the liquid storage box 3. The attraction between the magnet 41 and the iron block 34 ensures a tight seal between the top cover 4 and the liquid storage box 3, improving the sealing connection. Furthermore, the multiple corner magnets 41 ensure that the magnetic control component 5 can detect the position of the magnet 41 regardless of the angle at which the top cover 4 is closed onto the liquid storage box 3, thereby controlling the lifting of the top rod 6. A first sealing ring 42 is embedded in the bottom edge of the top cover 4, sealing the top cover 4 and the liquid storage box 3 together. The iron blocks 34 are distributed on the outside of the first sealing ring 42, which can improve the sealing between the top cover 4 and the liquid storage box 3. The magnetic control component 5 includes a magnetic sensor 51 and a control board 52 electrically connected to the magnetic sensor 51. The magnetic sensor 51 and the magnet 41 are inductively coupled. The output end of the control board 52 is electrically connected to the drive device. The magnetic sensor 51 will capture the position of the magnet 41, thereby detecting whether the top cover 4 is installed in place on the liquid storage box 3. When the magnetic sensor 51 detects that the top cover 4 is removed from the liquid storage box 3, it will control the drive device to run through the control board 52 and pull the top rod 6 down. When the magnetic sensor 51 detects that the top cover 4 is installed in place, it will control the drive device to run through the control board 52 and push the top rod 6 up.
[0032] like Figures 1-4 The snow machine body 1 shown has a vertically extending lifting channel 15 at the bottom of the mounting cavity 12. The top rod 6 is slidably disposed in the lifting channel 15. The driving device drives the top rod 6 to slide up and down in the lifting channel 15. The addition of the lifting channel 15 can improve the consistency of the vertical sliding direction of the top rod 6 in the snow machine body 1. Several second sealing rings 62 are fixedly sleeved on the top rod 6. The top rod 6 and the lifting channel 15 are sealed together by the second sealing rings 62. The second sealing rings 62 can prevent liquid leakage between the top rod 6 and the lifting channel 15 due to small gaps when the top rod 6 slides up and down in the lifting channel 15. The driving device is an electric cylinder 7. The push rod end of the electric cylinder 7 is fixedly connected to the bottom of the top rod 6.
[0033] The basic working principle of this utility model is as follows: A magnet 41 is set on the top cover 4, and a magnetic induction control component 5 and a drive device electrically connected to the magnetic induction control component 5 are set on the snow machine body 1. The drive device is used to drive the top rod 6 to rise and slide. The operator can remove the liquid container 2 from the snow machine body 1. At this time, the magnetic induction control component 5 senses that the magnet 41 is away and drives the top cover 4 to fall through the drive device, removing the top cover 4 from the liquid storage box 3. Beverage or water is then added to the liquid storage box 3. At this time, the sealing sleeve 33 of the opening of the drain pipe 31 is blocked by the ball bearing 32. After the liquid is replenished, the operator places the liquid storage box 3 into the mounting cavity 12 of the snow machine body 1. If the operator forgets to put the top cover 4 back on, the magnetic induction control component 5 cannot detect it. When the magnet 41 is in position, the drive device will not drive the push rod 6 to move upward, the ball 32 will always be in sealed engagement with the sealing sleeve 33, the drain pipe 31 will not discharge water, and the ice outlet channel 11 of the snow machine body 1 will not discharge snowflakes. When the top cover 4 is placed on the liquid storage box 3, the magnetic control component 5 will detect that the magnet 41 is in position and control the drive device to drive the push rod 6 to lift up, so that the push rod 6 lifts the ball 32 upward and moves it away from the sealing sleeve 33, thereby opening the lower end of the drain pipe 31 and enabling water to flow. This avoids the situation where the liquid level drops rapidly if the top cover 4 is not placed on the liquid storage box 3, thus improving the operational safety of the product. It has the effect of preventing the top cover 4 from being left on the top of the liquid storage box 3 and effectively improving the operational safety of the snow machine. Specific Implementation Example 2 A snowflake machine with a magnetic protection structure, such as Figure 5 As shown, the difference between this embodiment and specific embodiment one is that the driving device is a driving motor 8 and a driving gear 81. The driving motor 8 drives the driving gear 81 to rotate. The bottom of the top rod 6 is integrally provided with a rack part 61. The rack part 61 is slidably disposed in the lifting channel 15, and the driving gear 81 meshes with the rack part 61 for transmission.
[0035] The other structures of this embodiment are the same as those of Specific Embodiment 1, and will not be described again here.
[0036] 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.
