[0026] The present application provides a coffee machine as Figures 1-4The utility model provides an illustrated self -cleaning coffee machine, including coffee machine body 1, water tank 2 of fixed installation one side of coffee machine body 1 and the water tank of installation on coffee machine body 1, water tank 2 is fixedly installed to one side of coffee machine body 1, and the water tank includes the filter plate of fixed installation with coffee machine body 1 and the liquid containing box 4 that can vertically retract under filter plate, and the liquid containing box 4 includes with the bottom box 4a of fixed connection of coffee machine body 1 surface, the middle box 4b of sliding connection in bottom box 4a inner chamber and the top box 4c of sliding connection in middle box 4b inner chamber, and the first rubber strip 7 of fixed connection with both ends of top box 4c, the second rubber strip 8 of fixed connection with both ends of middle box 4b, and the first sliding slot 9 and the second sliding slot 10 of cooperation with first rubber strip 7 and second rubber strip 8 are opened on water tank 2 and coffee machine body 1, first rubber strip 7 and first sliding slot 9 slidingly connect, second rubber strip 8 and second sliding slot 10 slidingly connect, and the first sliding plate 4b1 of sliding connection with the inner wall of bottom box 4a and the first rib 4b2 of fixed connection in the top of first sliding plate 4b1 are included in middle box 4b, and the second sliding plate 4c1 of sliding connection with first rib 4b2, the second rib 4c2 of fixed connection in the bottom of second sliding plate 4c1 and the third rib 4c3 of fixed connection in the top of second sliding plate 4c1 are included in top box 4c, and the second rib 4c2 and first sliding plate 4b1 slidingly connect, first rubber strip 7 and second sliding plate 4c1 fixed connection, second rubber strip 8 and first sliding plate 4b1 fixed connection, the horizontal setting of the lever 11 of fixed connection with one side of third rib 4c3, the first buckle plate 12 of fixed connection with the top of lever 11, the second buckle plate 13 of fixed connection with first buckle plate 12 on one side of coffee machine body 1, when the top surface of third rib 4c3 and coffee machine body 1 fit, first buckle plate 12 and second buckle plate 13 buckle connection, the ultrasonic transducer 5 is installed in bottom box 4a, when the top of third rib 4c3 and coffee machine body 1 contact, bottom box 4a, middle box 4b, top box 4c, coffee machine body 1 and water tank 2 form sealed cleaning cavity 6, and the guide groove 15 of same shape with first rib 4b2 is vertically seted up on water tank 2 and coffee machine body 1, and first sliding slot 9 and second sliding slot 10 are all seted up in guide groove 15,
[0027] The drain pipe 14 is connected with the valve of the prior art hose. When it is necessary to clean the coffee liquid splashed on the coffee machine body 1, the water tank 2 and the filter plate, the valve needs to be closed, and then the user pushes the lever 11 upward by hand. The lever 11 drives the first clamping plate 12 and the third rib 4c3 to rise. When the third rib 4c3 rises in the guide groove 15, it drives the second slide plate 4c1 to rise. The second slide plate 4c1 drives the first rubber strip 7 to rise vertically in the first sliding groove 9, and also drives the second rib 4c2 to rise. When the top surface of the second rib 4c2 contacts the bottom surface of the first rib 4b2, it drives the first rib 4b2 to rise.

When the third rib 4c3 contacts the coffee machine body 1, the first clamping plate 12 and the second clamping plate 13 are clamped and connected. At this time, the bottom box 4a, the middle box 4b, the top box 4c, the coffee machine body 1 and the water tank 2 form a sealed cleaning cavity 6. Then the user operates the coffee machine body 1 to inject the water in the water tank 2 into the cleaning cavity 6 until the cleaning cavity 6 is filled with water. Then the ultrasonic transducer 5 is powered. The cavitation, radiation pressure, acoustic flow and other physical effects of ultrasonic waves in water are used to mechanically peel off the dirt on the cleaning object, achieving the purpose of cleaning the object. Then the valve is opened to drain the water in the cleaning cavity 6. Finally, the first clamping plate 12 and the second clamping plate 13 are separated by pulling the lever 11 downward, so that the top box 4c and the middle box 4b are reset. If the first cleaning is not clean enough, the first clamping plate 12 can be reset after the second cleaning or the third cleaning.
