Description

Technical Field

[0001] This utility model relates to the field of coffee machine technology, specifically a magnetic ring structure for coffee machines. Background Technology

[0002] A coffee machine is an automated device used to make coffee. Currently, coffee machines are becoming increasingly automated, with electronic technology being applied to them to automate the entire coffee-making process, including grinding, tamping, filling, brewing, and removing grounds.

[0003] Modern coffee machines incorporate a rotation meter to measure the travel of the brewing stopper. This meter includes a magnetic sleeve and a magnetic sensor. The magnetic sensor, located near the sleeve, senses changes in the magnetic field of the magnetic ring. Simultaneously, a magnetic interaction occurs between the float disc and the magnetic sleeve. The sleeve rises and falls with the float disc, and these changes in the magnetic field cause the magnetic sensor to rotate accordingly within an indicator, thus reflecting the volume of water in the bottle or the brewed coffee.

[0004] Currently, coffee machines often use ferrite cores in their cable delivery components. A ferrite core is a ring-shaped magnetic conductor and a common anti-interference component in electronic circuits. Passing a bundle of cables through a ferrite core creates a common-mode choke, effectively suppressing noise at different frequencies. Magnetic core inductors are already very common in electronic products. Existing magnetic core inductors typically use round copper wire wound around a magnetic core. When alternating current flows through the coil, a magnetic field line changes over time around it. This changing magnetic field line induces an electromotive force at the ends of the coil.

[0005] EMC, or Electromagnetic Compatibility, refers to the ability of a device or system to operate within its electromagnetic environment without causing unacceptable electromagnetic interference to any other equipment in that environment. Because the ferrite core on the power cord can interfere with the rpm metering device inside the coffee machine, the magnetic induction between the core and the sleeve weakens. Over time, this can affect the sensitivity of the magnetic sensor; therefore, storing the ferrite core on the power cord is necessary. Utility Model Content

[0006] This application provides a magnetic ring structure for a coffee machine, which is used to store and handle the magnetic ring on the cable output assembly, thereby reducing the impact of the magnetic ring on the coffee machine and increasing the lifespan of the rotation metering device for accurate measurement.

The fixing assembly 1 includes a fixing plate 11 and a fixing buckle 12 for fixing the magnetic ring sleeve 23. The fixing buckle 12 is rotatably mounted on the fixing plate 11. The fixing plate 11 has a fixing cavity 111 for receiving the fixing buckle 12. The magnetic ring sleeve 23 in the cable outlet assembly 2 is fixed in the fixing buckle 12 and housed in the fixing cavity 111, providing electromagnetic shielding for the magnetic ring sleeve 23. Furthermore, a partition 13 for magnetic shielding of the magnetic ring is provided on the cavity wall of the fixing cavity 111, thereby reducing the impact of the magnetic ring on the coffee machine and increasing the lifespan of the accurate measurement device.

[0034] Combination Figure 3 and Figure 4 The fixing buckle 12 includes a rotating plate 121, a rotating part 122 connected to the wall of the fixing cavity 111, a snap-fit ​​part 123 connected to the power connection line 22, and a clearance part 124 fixed to the magnetic ring sleeve 23. The rotating part 122, the snap-fit ​​part 123, and the clearance part 124 are all integrally connected to the rotating plate 121. Specifically, the rotating part 122 is provided with a rotating shaft (not shown in the figure) that is rotatably connected to the upper and lower walls of the fixing cavity 111. In addition, power connection lines 22 are provided at both ends of the magnetic ring sleeve 23, and the snap-fit ​​parts 123 are located on both sides of the clearance part 124.

[0035] Furthermore, the latching part 123 has an opening 1231 for the power connection cable 22 to pass through. The latching part 123 has a clearance hole 1232 for the power connection cable 22 to pass through on the side wall of the opening 1231.

[0036] Furthermore, a positioning groove 1111 is provided on the cavity wall of the fixed cavity 111 at the connection of the rotating shaft, and the upper and lower groove walls of the positioning groove 1111 are connected to the upper and lower ends of the rotating shaft. The design of the positioning groove 1111 in this application facilitates the rotation of the rotating plate 121, thereby making it easier to store the magnetic ring in the fixed cavity 111.

[0037] In this embodiment, when the power connection cable 22 is not needed, the magnetic ring sleeve 23 is snapped onto the relief portion 124, and the power connection cable 22 is fixed onto the snapping portion 123. The magnetic ring is then fixed in the fixing cavity 111 by rotating the rotating plate 121, reducing the impact of the magnetic ring on the coffee machine. When the power connection is needed, the magnetic ring is removed from the fixing cavity 111 by rotating the rotating plate 121, and the power connection cable 22 can be directly inserted into the power source. Alternatively, the power connection cable 22 can be removed from the snapping portion 123, and the magnetic ring sleeve 23 can be removed from the relief portion 124, thus facilitating the direct insertion of the power connection cable 22 into the power source.

[0038] Reference Figure 5 The fixed plate 11 has a storage cavity 131 on the cavity wall of the fixed cavity 111 for the partition 13 to slide and be stored. The upper and lower ends of the partition 13 are integrally provided with sliders 132, and the upper and lower side walls of the storage cavity 131 are provided with sliding grooves 133 for the sliders 132 to slide, so that the partition 13 can slide in the storage cavity 131 to close the fixed cavity 111. At the same time, the sliders 132 are set in the sliding grooves 133 to further improve the stability of the partition 13 sliding in the storage cavity 131.

[0039] Furthermore, in combination Figure 6A positioning block 134 is integrally provided on the side of the partition 13 facing away from the receiving cavity 131. A positioning hole 112 is provided on the cavity wall of the fixing plate 111 for the positioning block 134 to be positioned and engaged. The positioning block 134, passing through the positioning hole 112, further enhances the fixing ability of the partition 13 in closing the fixing cavity 111, thereby achieving the closure of the fixing cavity 111 by the partition 13. Furthermore, a guide surface 135 is provided on the positioning block 134 for engaging with the positioning hole 112, which helps to fix the positioning block 134 in the positioning hole 112. Further, a handle is provided on the partition 13. In this embodiment, by pressing the partition 13, the guide surface 135 on the positioning block 134 is misaligned with another guide surface 135 on the positioning hole 112, thereby enabling the partition 13 to slide.

[0040] See also Figure 2 The fixing plate 11 has a limiting groove 113 for the power connection cable 22. One end of the cavity of the limiting groove 113 communicates with the cavity of the fixing cavity 111, and the other end of the cavity of the limiting groove 113 communicates with the cavity around the cable outlet hole. This design allows the power connection cable 22 to be arranged in the limiting groove 113, reducing the space occupied.

[0041] Furthermore, the partition 13 in this application has a three-layer structure, including two first partitions 13 and a second partition 13 fixedly disposed between the two first partitions 13. The first partitions 13 are made of aluminum alloy, and the second partitions 13 are made of steel.

[0042] Furthermore, the cavity wall of the fixed cavity 111 has a double-layer structure. The wall closer to the cavity is the outer wall, and the wall further away is the inner wall. The outer wall is made of aluminum alloy, and the inner wall is made of steel. Through the partition 13 and the multi-layer structure of the cavity wall of the fixed cavity 111, the magnetism of the magnetic ring can be effectively shielded, preventing the magnetic field generated by the magnetic ring from being transmitted outward. This avoids the superposition of magnetic fields generated by a large number of magnetic rings during storage and transportation, thus preventing the magnetic ring from affecting the coffee machine and increasing the lifespan of the accurate measurement of the revolution meter.
