[0027] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0028] like Figures 1-7As shown, this coffee machine with a milk tank includes a coffee machine body 1, on which a grinding mechanism and a brewing mechanism are provided. The grinding mechanism and the brewing mechanism are arranged vertically from top to bottom. A milk tank assembly for producing milk foam is provided on the outside of the coffee machine body 1. The milk tank assembly is connected to the brewing mechanism through a pipe. By setting up the milk tank assembly, the coffee machine can have the function of making milk foam, making the overall function of the coffee machine more comprehensive. At the same time, it also optimizes the internal layout of the coffee machine body 1. That is, the grinding mechanism and the brewing mechanism are arranged vertically from top to bottom, so that the width space occupied by the coffee machine can be relatively reduced, and the overall width will not be significantly increased after the milk tank assembly is added.

[0029] Furthermore, the milk container assembly includes a milk container body 2 and a foaming device 21. The milk container body 2 has a milk storage chamber (not shown in the figure). The foaming device 21 is located above the milk storage chamber inside the milk container body 2. The foaming device 21 has a steam interface 211 and an output interface 212 for outputting steam or milk foam. There is a foaming chamber 213 between the steam interface 211 and the output interface 212. The coffee machine body 1 is equipped with a steam generator 23. The steam generator 23 is connected to the steam interface 211 through a pipe. The outside of the foaming device 21 is equipped with a milk suction pipe 214 that communicates with the foaming chamber 213 and is used to suck milk from the milk storage chamber into the foaming chamber 213, and an air suction pipe 215 that is used to suck external air into the foaming chamber 213. After the steam generated by the steam generator 23 enters the foaming chamber 213, it will generate negative pressure. Under the action of negative pressure, the milk suction pipe 214 and the air suction pipe 215 will simultaneously suck milk and air into the foaming chamber 213 and mix them with the steam to achieve the effect of foaming milk.

[0030] Furthermore, a steam nozzle 216 is provided between the foaming chamber 213 and the steam interface 211. The steam nozzle 216 is provided with an ejector chamber 2161 on the side near the foaming chamber 213. The ejector chamber 2161 is conical in shape, and the width of the ejector chamber 2161 decreases along the direction of steam flow. This can effectively increase the speed of steam entering the foaming chamber 213, so that the foaming chamber 213 can generate a stronger negative pressure and can better absorb milk in the milk storage chamber and external air.

[0031] Furthermore, a mixing chamber 217 is provided between the foaming chamber 213 and the output interface 212. The mixing chamber 217 extends along the direction of steam flow. The width of the mixing chamber 217 is greater than the width of the steam outlet of the foaming chamber 213. The speed of the mixed fluid of steam, milk and air entering the mixing chamber 217 can be relatively reduced, increasing the mixing time and making the milk foaming effect more uniform.

[0032] Furthermore, the brewing mechanism includes a water pump 31, a heater 32, and a brewing assembly 33 connected sequentially via water channels. The water outlet of the water pump 31 is also connected to the steam generator 23. The coffee machine body 1 is provided with a brewing chamber 11. The water pump 31, the steam generator 23, and the heater 32 are located in the brewing chamber 11. The brewing assembly 33 is located below the grinding mechanism. The brewing assembly 33 is provided with a liquid outlet below it. The liquid outlet is located on the upper side of the brewing liquid outlet area 12. The horizontal projection of the brewing liquid outlet area 12 along the left and right sides is U-shaped, which provides a relatively large operating space for the user when brewing coffee powder, making the operation easier.

[0033] Furthermore, the milk tank assembly is located on the outside of the coffee machine body 1, adjacent to the brewing and dispensing area 12, which allows for a relatively smaller pipe length related to the milk tank assembly, making the equipment layout more compact and reasonable.

[0034] Furthermore, the coffee machine body 1 is equipped with a solenoid valve 4. The outlet end of the steam generator 23 is connected to the inlet end of the solenoid valve 4. The solenoid valve 4 has a connector 41 set on the side wall of the coffee machine body 1. The connector 41 is detachably connected to the steam interface 211. The connector 41 and the steam interface 211 are connected and fixed by a locking device. The solenoid valve 4 can control the state of steam entering the foaming device 21. At the same time, it can realize the quick assembly and disassembly of the milk tank assembly and the coffee machine body 1, which is convenient for the overall packaging or storage of the equipment.

[0035] Furthermore, the heater 32 and the steam generator 23 are arranged vertically from top to bottom. The brewing chamber 11 is provided with a mounting bracket 5. The mounting bracket 5 is provided with a first mounting cavity 51, a second mounting cavity 52 and a third mounting cavity 53 corresponding to the water pump 31, the heater 32 and the steam generator 23, respectively. The first mounting cavity 51 is spaced apart from the second mounting cavity 52 and the third mounting cavity 53 in the left and right direction. The second mounting cavity 52 and the third mounting cavity 53 are spaced apart in the up and down direction. This can make better use of the vertical space and make the layout of the water pump 31, the heater 32 and the steam generator 23 more compact and easier to install.

[0036] Furthermore, the grinding mechanism includes a bean hopper 61 and a grinding assembly 62 arranged vertically from top to bottom. The upper part of the bean hopper 61 is open and connected to a detachable hopper cover (63). The bean hopper 61 extends at least partially outward to the top of the coffee machine body 1. The coffee machine body 1 is provided with a grinding chamber 13, and the grinding assembly 62 is located in the grinding chamber 13. This makes full use of the vertical space of the equipment and allows the user to conveniently add coffee beans to the bean hopper 61.

[0037] Furthermore, the upper horizontal height of the mounting bracket 5 is lower than the horizontal height of the grinding assembly 62, and the vertical projection of the mounting bracket 5 is at least partially offset from the vertical projection of the grinding mechanism. The vertical projection of the grinding mechanism covers the vertical projection of the brewing assembly 33, making the layout of the brewing mechanism and the grinding mechanism more compact in the front-to-back direction, and further optimizing the overall size of the coffee machine.
