[0019] To further elaborate on the technical means and effects adopted by this application to achieve the intended purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation manners, structures, features, and their effects according to this application as follows. In the following description, different "one embodiment" or "embodiment" do not necessarily refer to the same embodiment. In addition, the specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0020] As Figure 1 and Figure 2 shown, the silent cooking machine includes a machine base 1, a cooking cup 2 located on the machine base 1, a stirrer 4 placed in the cooking cup 2, a driver 3 located in the machine base 1 and drivingly connected to the stirrer 4, and a silent cover 5 covering the outside of the cooking cup 2. The silent cover 5 is provided with an external exhaust port 51; the top end of the cooking cup 2 is provided with a cup cover, and an internal exhaust port 21 is provided on the cup cover; an exhaust valve assembly is assembled in the external exhaust port 51, and the exhaust valve assembly includes a valve seat 7 and a valve core 8 installed in the valve seat 7.

[0021] Further in combination with Figures 3 - 5 shown, the valve seat 7 includes a valve cylinder 71 and a valve cover 72 provided at the top end of the valve cylinder 71. The valve cylinder 71 passes through the external exhaust port 51 and is inserted downward into the internal exhaust port 21. The valve cover 72 abuts against the external exhaust port 51 of the silent cover 5. The top end of the valve cylinder 71 exposes outside the valve cover 72 to form an insertion port 710 for the valve core 8 to be inserted into the inside of the valve cylinder 71; the valve core 8 includes a core cylinder 81 and a core cover 82 provided at the top end of the core cylinder 81. An exhaust groove 83 is provided on the core cover 82. An air inlet 810 is provided at the bottom end of the core cylinder 81. A gas distribution port 812 communicating with the air inlet 810 is provided at the lower end of the core cylinder 81. A non-linear baffle 813 is provided on the outer side surface of the core cylinder 81; the core cylinder 81 is limited and assembled in the valve cylinder 71, and the core cover 82 abuts against the valve cover 72 so that the exhaust groove 83 is exposed outside the valve cover 72. A non-linear bubble-breaking channel 80 is formed jointly by the baffle 813 and the inner wall of the valve cylinder 71. The bubble-breaking channel 80 communicates between the gas distribution port 812 and the exhaust groove 83.

[0022] By forming a non-linear bubble-breaking channel 80 between the valve core 8 and the valve seat 7, the path for the bubbles to enter the bubble-breaking channel 80 and move towards the exhaust groove 83 is not a straight line, causing the bubbles to burst when the path changes during the movement process, thereby improving the bubble-breaking effect, avoiding bubble blockage, and smooth exhaust is beneficial to improving the use safety of the cooking machine.

[0023] The baffle 813 is provided with a bent portion, so that the bent portion has a bubble-breaking tip 8131 located inside the bubble-breaking channel 80, enabling the bubbles to be pricked by the bubble-breaking tip 8131 when passing through the bent portion in the bubble-breaking channel 80, improving the bubble-breaking ability during the movement of the bubbles in the bubble-breaking channel 80, and making the exhaust of the cooking machine smoother.

[0024] The number of exhaust grooves 83 is two; the number of baffle walls 813 is two, and a bubble-breaking channel 80 is formed between the inner and outer sides of the two baffle walls 813 respectively.

[0025] A sealing groove 74 is provided on the outer side surface of the lower end of the valve cylinder 71, and a sealing ring 9 is provided in the sealing groove 74. The lower end of the valve cylinder 71 is hermetically connected to the inner wall of the inner exhaust port 21 of the cup lid by using the sealing ring 9, so that the bubbles and gas in the cooking cup 2 will not leak from the outer side surface of the valve cylinder 71, but will concentrate on entering from the air inlet 810 at the bottom end of the core cylinder 81 and be discharged from the exhaust groove 83 through the bubble-breaking channel 80.

[0026] The lower end of the core cylinder 81 is provided with a first limit buckle 811. When the core cylinder 81 is inserted into the valve cylinder 71, the bottom end of the core cylinder 81 extends downward out of the valve cylinder 71, and the first limit buckle 811 is buckled and connected to the bottom end of the core cylinder 81 to limit and assemble the valve core 8 in the valve seat 7.

[0027] A buckling position 73 is provided on the outer side surface of the valve cylinder 71, and a second limit buckle 52 is provided on the inner wall of the outer exhaust port 51. When the valve seat 7 is inserted into the outer exhaust port 51, the valve seat 7 can be properly rotated to make the second limit buckle 52 screw into the buckling position 73 so that the second limit buckle 52 is buckled with the buckling position 73, realizing the fixed assembly of the exhaust valve assembly on the silent cover 5.

[0028] Working principle of the silent cooking machine:

[0029] 1. Before use, remove the silent cover 5 and the cup lid of the cooking cup 2, and put the ingredients to be processed into the cooking cup 2 as required.

[0030] 2. Cover the cup lid, then install the silent cover 5 to the outside of the cooking cup 2, insert the exhaust valve assembly from the outer exhaust port 51, and apply force through the valve cover 71 to properly rotate the valve seat 7 to make the second limit buckle 52 screw into the buckling position 73 so that the second limit buckle 52 is buckled with the buckling position 73.

[0031] 3. Let the driver 3 be powered on and started. The driver 3 generally uses an electric motor, and the stirrer 4 is driven by the driver 3 to process the ingredients in the cooking cup 2.

[0032] 4. The bubble and steam mixture generated during the processing of the ingredients enters from the air inlet 810 at the lower end of the core cylinder 81, is shunted to the two bubble-breaking channels 80 through the air distribution port 812, and the bubbles are broken through the bent bubble-breaking channel 80, and the steam is smoothly discharged from the exhaust groove 83.

[0033] It can be seen that the silent cooking machine has excellent bubble-breaking performance due to the adoption of the exhaust valve assembly, is not prone to bubble blockage during use, and thus has smooth exhaust.

[0034] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
