Description

Technical Field

[0001] This application relates to the field of coffee machine technology, and more specifically, to a nozzle flow control device for a fully automatic coffee machine. Background Technology

[0002] Coffee is one of the world's most popular beverages, bringing pleasure and excitement. With my country's reform and opening up, the world's most popular coffees, such as Italian espresso, cappuccino, and latte with milk, have also appeared on Chinese tables and are increasingly loved. The application of electronic technology to coffee machines has enabled the automatic control of the entire coffee brewing process, including grinding, tamping, filling, brewing, and removing grounds, thus creating the modern coffee machine.

[0003] A search revealed that the publication (announcement) number CN222109869U discloses "a coffee machine anti-spray device, which is installed inside the coffee machine. The anti-spray device includes two coffee nozzles, a two-position four-way solenoid valve for switching the coffee nozzles, and an indicator light. Each coffee nozzle is equipped with a water pressure sensor, and the input ends of the two coffee nozzles are connected to the output end of the solenoid valve... This utility model can automatically switch the blocked nozzles through the solenoid valve and pressure sensor to avoid excessive internal pressure in the nozzles causing splashing and reducing safety hazards." However, the flow rate of the coffee nozzles in this application is not controllable and adjustable, which reduces the practicality of the device.

[0004] To address the aforementioned issues, this application provides a fully automatic coffee machine nozzle flow control device. Utility Model Content

[0005] One objective of this application is to provide a nozzle flow control device for a fully automatic coffee machine, comprising a fully automatic coffee machine body, a circular block mounted on the fully automatic coffee machine body, the circular block having multiple liquid outlet holes, a circular groove on the surface of the circular block, a matching rotating plate rotatably connected inside the circular groove, a circular hole on the rotating plate, a toothed ring rotatably connected to the outer side of the circular block, a support plate one and a support plate two fixedly connected to the outer side of the circular block, a limit plate fixedly connected between the support plate one and the support plate two, a lead screw rotatably connected to the inner side of the limit plate, a rack plate slidably connected to the inner side of the limit plate, and the rack plate being threaded onto the outer side of the lead screw, and a rotating ring rotatably connected to the outer side of the circular block.

[0006] Furthermore, an annular groove is provided on the outer side of the circular block, and the toothed ring is rotatably connected inside the annular groove.

[0007] Furthermore, the toothed ring is meshed and connected to the rack plate, and the limiting plate is arranged in a "U" shape.

[0008] Furthermore, both ends of the lead screw are rotatably connected to the inner wall of the limiting plate via bearings, and one end of the lead screw extends to the outer side of the limiting plate and is fixedly connected to a rotating handle.

[0009] Furthermore, the rack plate is slidably connected between support plate one and support plate two, and the toothed ring is disposed between support plate one and support plate two.

[0010] Furthermore, one end of the rotating ring is fixedly connected to the surface of the rotating plate, and the other end of the rotating ring is fixedly connected to the toothed ring.

[0011] Furthermore, the circular block has a threaded groove on the side away from the rotating plate that communicates with the liquid outlet, and the circular block is threadedly fitted onto the outside of the fully automatic coffee machine body.

[0012] The beneficial effects of this application are:

[0013] The screw is rotated by turning the handle. The rotation of the screw causes the rack plate to move linearly between support plate one and support plate two. The movement of the rack plate drives the gear ring to rotate. The rotation of the gear ring drives the rotating ring to rotate. The rotation of the rotating ring drives the rotating plate to rotate, which in turn drives the circular hole to rotate. The rotation of the circular hole changes the size of the overlapping area with the liquid outlet, thereby changing the liquid flow rate and improving the practicality of the device.

[0024] Example:

[0025] Please see Figure 1 , Figure 2 and Figure 3 This application discloses a nozzle flow control device for a fully automatic coffee machine, including a fully automatic coffee machine body 1. The fully automatic coffee machine body 1 belongs to the prior art, and its structure and working principle are based on a coffee machine anti-spray device with publication (announcement) number CN222109869U, which will not be described in detail here. A circular block 3 is installed on the fully automatic coffee machine body 1. The circular block 3 has multiple liquid outlet holes 11 arranged in a ring array. A circular groove 14 is opened on the surface of the circular block 3. A matching rotating plate 2 is rotatably connected inside the circular groove 14. A circular hole 9 is opened on the rotating plate 2. Multiple circular holes 9 are arranged in a ring array. A toothed ring 8 is rotatably connected to the outside of the circular block 3. An annular groove 12 is opened on the outside of the circular block 3. The toothed ring 8 is rotatably connected inside the annular groove 12. A support plate 1 5 and a support plate 2 7 are fixedly connected to the outside of the circular block 3.

[0026] A limiting plate 6 is fixedly connected between support plate 5 and support plate 7. A lead screw 10 is rotatably connected to the inner side of the limiting plate 6, and a rack plate 13 is slidably connected to the inner side of the limiting plate 6. A gear ring 8 is meshed with the rack plate 13 for transmission, driving the lead screw 10 to rotate. The rotation of the lead screw 10 causes the rack plate 13 to move linearly between support plate 5 and support plate 7. The movement of the rack plate 13 drives the gear ring 8 to rotate. The rotation of the gear ring 8 drives the rotating ring 4 to rotate. The rotation of the rotating ring 4 drives the rotating plate 2 to rotate, which in turn drives the circular hole 9 to rotate. The rotation of the circular hole 9 changes the size of the overlapping area with the liquid outlet hole 11, thereby changing the liquid flow rate. The limiting plate 6 is set in a "U" shape, and the rack plate 13 is threaded onto the outer side of the lead screw 10. The outer side of the circular block 3 is rotatably connected to the rotating ring 4.

[0027] Please see Figure 3 Both ends of the lead screw 10 are rotatably connected to the inner wall of the limiting plate 6 through bearings. One end of the lead screw 10 extends to the outside of the limiting plate 6 and is fixedly connected to a rotating handle. The rotating handle facilitates the screw 10. The rack plate 13 is slidably connected between the first support plate 5 and the second support plate 7, thereby using the first support plate 5 and the second support plate 7 to slide and limit the rack plate 13. The toothed ring 8 is set between the first support plate 5 and the second support plate 7.

[0028] Please see Figure 3 One end of the rotating ring 4 is fixedly connected to the surface of the rotating plate 2, and the other end of the rotating ring 4 is fixedly connected to the toothed ring 8. When the toothed ring 8 rotates, it can drive the rotating ring 4 to rotate. When the rotating ring 4 rotates, it can drive the rotating plate 2 to rotate. The side of the round block 3 away from the rotating plate 2 is provided with a threaded groove (not shown in the figure) that communicates with the liquid outlet hole 11. The coffee nozzle of the fully automatic coffee machine body 1 is provided with an external thread. The round block 3 and the coffee nozzle are movably connected by a matching threaded groove and an external thread. The threaded connection makes it easy to disassemble the round block 3. The round block 3 is threadedly sleeved on the outside of the fully automatic coffee machine body 1.

[0029] The implementation principle of this application embodiment is as follows: the screw 10 is rotated by rotating the handle. The rotation of the screw 10 causes the rack plate 13 to move linearly between the support plate 5 and the support plate 7. The movement of the rack plate 13 drives the gear ring 8 to rotate. The rotation of the gear ring 8 drives the rotating ring 4 to rotate. The rotation of the rotating ring 4 drives the rotating plate 2 to rotate, which in turn drives the circular hole 9 to rotate. The rotation of the circular hole 9 changes the size of the overlapping area with the liquid outlet hole 11, so as to change the liquid flow rate.

[0030] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and application concept of this application, should be included within the scope of protection of this application.
