Description

Technical Field

[0001] This application relates to the field of beverage preparation apparatus, and in particular to a cold drink machine with a safety mechanism. Background Technology

[0002] A beverage freezer is a small, efficient freezing system that uses a combination of refrigeration cycles and forced stirring to partially freeze the beverage and break it into tiny ice crystals.

[0003] In related technologies, a beverage cooler includes a mounting housing, a refrigeration mechanism disposed within the mounting housing, a beverage container detachably mounted to the mounting housing, and a stirring mechanism disposed within the beverage container. The beverage container includes a body and a lid for closing the top of the body, and the mounting housing has a mounting base for mounting the body. When using the beverage cooler to dispense cold drinks, the operator first needs to mount the container to the mounting base, pour the liquid into the container, tightly close the lid, and then turn on the switch to start the refrigeration and stirring mechanisms of the beverage cooler.

[0004] Regarding the aforementioned technologies, the inventors believe that when using the beverage maker, the operator may accidentally touch the switch, causing the beverage maker to start. If the beverage end cap is not tightly closed to the container, the high-speed stirring mechanism may cause liquid to splash. Utility Model Content

[0005] In order to reduce the risk of liquid splashing caused by the stirring mechanism due to operator misoperation when starting the beverage machine, this application provides a beverage machine with a safety mechanism.

[0006] The cold drink machine with a safety mechanism provided in this application adopts the following technical solution: A beverage cooler with a safety mechanism includes a housing, a beverage container detachably mounted on the housing, and a beverage end cap. The housing has a side shell located on one side of the beverage container. The beverage end cap is provided with a Hall effect trigger, and the side shell is provided with a Hall effect switch that cooperates with the Hall effect trigger. The Hall effect switch is connected in series with the power supply of the beverage cooler and is used to control the power supply of the beverage cooler. The beverage end cap is circumferentially movably arranged at the upper opening of the beverage container and has a working position and a stationary position. When the beverage end cap is in the working position, the Hall effect trigger of the beverage end cap triggers the Hall effect switch, and the Hall effect switch is connected. When the beverage end cap is in the stationary position, the Hall effect trigger of the beverage end cap disengages from the Hall effect switch, and the Hall effect switch is disconnected.

[0007] By adopting the above technical solution, when using the beverage machine, the operator first installs the beverage container onto the machine casing and adds beverage into the container, then installs the beverage end cap onto the top of the container. Using a Hall effect trigger in conjunction with a Hall effect switch, the power supply to the beverage machine can be controlled according to the position of the beverage end cap. When the beverage end cap is in the working position, the Hall effect trigger on the beverage end cap triggers the Hall effect switch to power on the beverage machine. When the beverage end cap is in the stationary position, the Hall effect trigger on the beverage end cap disengages from the Hall effect switch to power off the beverage machine. This improves the safety and convenience of using the beverage machine and helps reduce the risk of liquid splashing caused by the stirring mechanism due to operator error in starting the beverage machine.

[0008] Optionally, the lower end of the beverage cap is provided with a first sealing ring that seals with the upper end of the beverage container, and the first sealing ring is provided with a first damping ring on the side facing the beverage container.

[0009] By adopting the above technical solution, a first sealing ring is circumferentially set at the lower end of the beverage cap and seals with the upper end of the beverage tube, which helps to reduce the risk of beverage splashing; a first damping ring is set on the side of the first sealing ring facing the beverage tube, which helps to increase the friction between the beverage tube and the beverage cap, reduces the probability of the beverage cap rotating circumferentially at the top of the beverage tube, and makes the cooperation between the Hall trigger and the Hall switch more stable.

[0010] Optionally, the top of the beverage end cap has a handle structure; the handle structure includes a handle seat disposed on the top of the beverage end cap and a handle cover adapted to the top of the handle seat; one end of the handle seat is disposed in the middle of the beverage end cap, and the other end of the handle seat is disposed on the outer edge of the beverage end cap; the mounting base has an arrangement groove for arranging the Hall trigger at the top of one end of the outer edge of the beverage end cap.

[0011] By adopting the above technical solution, the handle structure allows users to easily switch between the working position and the stationary position of the beverage end cap; the handle structure composed of the handle base and the handle cap facilitates the arrangement of the Hall trigger, makes reasonable use of the space of the beverage end cap, and at the same time, the top of one end of the handle base on the outer edge of the beverage end cap is opened for the arrangement of the Hall trigger, which helps to ensure the accurate position of the Hall trigger so as to cooperate with the Hall switch to control the power on and off of the beverage machine.

[0012] Optionally, the top of the handle base has a first weight-reducing groove along its length, and the handle base has symmetrically arranged locking grooves on both sides of the inner wall of the first weight-reducing groove. The handle base is provided with a first locking member at the bottom of the locking groove for locking the handle cover. The bottom of the handle cover has a second weight-reducing groove along its length, and the handle cover is provided with a second locking member at the bottom of the second weight-reducing groove that cooperates with the first locking member. The handle cover has abutting protrusions on both sides of the second weight-reducing groove for abutting against the outer walls of both sides of the handle base.

[0013] By adopting the above technical solution, a first weight-reducing groove is opened at the top of the handle seat and a second weight-reducing groove is opened at the bottom of the handle cover, which helps to reduce the overall weight of the beverage end cap; the handle seat cooperates with the second locking member of the handle cover through the first locking member, and the abutting protrusion of the handle cover abuts against the outer wall of the handle seat, thus realizing a stable connection between the handle cover and the handle seat.

[0014] Optionally, the first locking member includes a first elastically deformable portion disposed at the bottom of the locking groove and a locking protrusion disposed on the side of the first elastically deformable portion facing the first weight-reducing groove; the second locking member has a hook head that engages with the locking protrusion.

[0015] By adopting the above technical solution, a specific snap-fit ​​structure between the first locking member and the second locking member is disclosed. The first deformation part with elasticity allows the locking protrusion to deform flexibly, and the hook head of the second locking member is used to achieve a stable and easy-to-disassemble connection between the handle seat and the handle cover, which helps to improve the convenience of the installation and disassembly of the handle cover.

[0017] By adopting the above technical solution, the two sets of first locking parts and the two sets of second locking parts cooperate to make the handle cover more securely installed on the handle seat, which helps to improve the connection stability and reliability of the handle structure.

[0018] Optionally, the housing has a mounting base for arranging the beverage can, the beverage can has a mounting part that mates with the mounting base, and the inner surface of the mounting part is provided with snap-fit ​​protrusions; the mounting base has a snap-fit ​​groove for engaging the snap-fit ​​protrusions; the snap-fit ​​groove includes a first snap-fit ​​groove arranged perpendicular to the bottom surface of the mounting base and a second snap-fit ​​groove connected to the bottom of the first snap-fit ​​groove.

[0019] By adopting the above technical solution, a specific connection structure between the beverage can and the machine housing is disclosed. By using the snap-fit ​​protrusion of the mounting part to cooperate with the snap-fit ​​groove of the mounting base, the beverage can is stably installed on the mounting base of the machine housing. The vertical first snap-fit ​​groove facilitates the vertical insertion of the beverage can during installation, while the second snap-fit ​​groove at the bottom further ensures the stability of the snap-fit, making it difficult for the beverage can to loosen or detach from the machine housing.

[0020] Optionally, the number of the snap-fit ​​protrusions is four and they are evenly spaced on the inner surface of the mounting part, and the side of the mounting base has snap-fit ​​grooves for the four snap-fit ​​protrusions to engage one by one.

[0021] By adopting the above technical solution, the four evenly spaced snap-fit ​​protrusions cooperate with the corresponding snap-fit ​​grooves on the side of the mounting base, so that the beverage can be installed more stably on the mounting base of the machine casing, further reducing the risk of the beverage can shaking or shifting, and ensuring the normal operation of the cold drink machine.
