[0050] By arranging the drainage passage, the water outlet hole 611 and the drainage port 22 form an interface, guiding the accumulated water in the water collecting cavity 61 to flow out of the shell 20 through the drainage port 22, avoiding the problem of incomplete drainage caused by splashing during the drainage process, and improving the waterproof effect of the shell 20.

[0051] Of course, in fact, the water collecting cavity 61 can also serve as a water collecting function without draining water, and the water accumulated in the water collecting cavity 61 can be dried by the heat of the motor.

[0052] In a preferred embodiment, as shown in Figures 1-3 , regarding the heat dissipation air inlet path of the motor 30, the soybean milk machine further comprises a heat dissipation cover 40 covering the outside of the motor 30 to enclose a heat dissipation cavity, the volute 60 is provided with an inlet for the heat dissipation fan 50 to extend into, the lower end of the heat dissipation cover 40 interfaces with the inlet, and the outside of the heat dissipation cover 40 is further provided with an air inlet passage 41 in communication with the heat dissipation cavity, and the shell 20 is provided with an air inlet 23 in communication with the air inlet passage 41.

[0055] In this embodiment, the heat sink 40 is arranged outside the motor 30, the heat sink 40 further collects airflow, so that a large amount of airflow can pass through the motor 30 to cool the motor 30, and then pass through the inlet of the volute 60 to be collected in the volute 60 and then be discharged, so that the airflow is exchanged, the motor 30 is reliably cooled, the air inlet 23 is arranged on the shell 20 through the air inlet channel 41, and the airflow can flow along the set route, so that the airflow flows smoothly and the cooling effect is improved.

[0056] Of course, in another preferred embodiment, the volute 60 can also be provided with no air guide channel 62, and the air inlet channel 41 is only limited, for example, the volute 60 is provided with a limiting hole in the side portion, and the air inlet channel 41 passes through the limiting hole to communicate with the air inlet 23.

[0057] The limiting hole is arranged on the volute 60 to limit the air inlet channel 41, so that the air inlet channel 41 and the air inlet 23 are reliably connected, the airflow flows smoothly, and the limiting of the volute 60 and the heat sink 40 is reliable.

[0058] The water flow discharge path of the water collection cavity 61 can be selected as any one of the following embodiments 1-3.

[0059] Embodiment 1, as shown in Figures 1-7 , the water flow discharge path of the water collection cavity 61 is independent of the air discharge path of the volute 60 and does not interfere with each other.

[0060] In this embodiment, as shown in Figure 6 、 7 , the water collection cavity 61 is provided with a water outlet hole 611 outside the air discharge channel 63, for example, the water collection cavity 61 includes a main cavity 612 located directly above the air discharge channel 63 and an extension cavity 613 extending laterally from the main cavity 612 and protruding from the air discharge channel 63, the main cavity 612 is in communication with the extension cavity 613, and the water outlet hole 611 is arranged on the cavity wall of the extension cavity 613, and the base 21 is provided with a drain port 22 located below the water outlet hole 611.

[0062] In this embodiment, the water collection cavity 61 has a water outlet 611 located outside the exhaust channel. Therefore, the water flow path through the water collection cavity in the socket 201 is isolated and independent from the airflow exhaust path of the exhaust channel, and they do not interfere with each other. This achieves smooth discharge of airflow and water flow, reduces wind noise caused by water flow obstruction during heat dissipation, reduces heat dissipation noise, and avoids the situation where water flow is blown away by airflow and is difficult for users to clean, thus improving the user experience.

[0063] By setting the water collection chamber 61 to include an extension chamber 613 protruding from the exhaust channel 63, the volume of the water collection chamber 61 is increased, improving the water collection effect and enhancing the waterproofness of the soymilk maker. On the other hand, by opening a water outlet 611 in the cavity wall of the extension chamber 613, the water discharge path in the water collection chamber 61 and the exhaust path of the exhaust channel 63 do not interfere with each other. The water in the water collection chamber 61 is directly discharged from the outer casing 20 through the water outlet 611 and the drain hole, avoiding the formation of a humid environment inside the outer casing 20 that could breed bacteria or odors, thus improving the safety of use.

[0064] In Implementation Example 2, the water discharge path of the water collection chamber 61 and the air exhaust path of the volute 60 are still independent and do not interfere with each other. The difference from Implementation Example 1 is the position of the water outlet 611 of the water collection chamber 61.

For example, the top wall of the exhaust channel 63 is provided with a wall extending from bottom to top. The wall and the top wall of the exhaust channel 63 enclose the water collection cavity 61. The water outlet 611 is provided in the wall. The base 21 is provided with a drain outlet 22 communicating with the water outlet 611.

[0066] The water collection cavity 61 is formed by the enclosure wall and the top wall of the exhaust duct 63, which simplifies the structure of the volute 60. The water outlet 611 is opened on the enclosure wall, so that the water discharge path in the water collection cavity 61 and the exhaust path of the exhaust duct 63 do not interfere with each other, reducing exhaust noise and preventing water from being blown away by the airflow after discharge, which would cause trouble for users. By setting the drain outlet 22, the water collected in the water collection cavity 61 is discharged, so as to dry the internal environment of the outer shell 20 and improve the safety of use.

[0067] In the embodiment, the shell 20 comprises the base 21 located at the bottom, the base 21 is provided with the air outlet 24, the volute 60 comprises the air outlet channel 63 extending to and abutting the air outlet 24, and the water collecting cavity 61 is communicated with the outside through the air outlet channel 63 and the air outlet 24.
