The sealing sleeve 230 is sleeved on the protrusion 210 and fills the first waterproof labyrinth 220 .

[0042] By setting a plurality of studs 141 and hollow columns 152, the hollow columns 152 are first sleeved on the outside of the studs 141 to achieve the initial installation of the pressing block 150. Then, the user can bolt the pressing block 150 to the positioning plate 140 through the studs 141 to achieve the secondary installation of the pressing block 150 while ensuring that the pressing block 150 stably presses against the sealing sleeve 230, thereby effectively improving the installation stability of the sealing sleeve 230.

[0043] Reference Figure 5 As shown, it can be understood that the inner wall of the sealing sleeve 230 is provided with a positioning protrusion 231, which is arranged to protrude inwardly along the radial direction of the sealing sleeve 230, and the outer wall of the protrusion 210 is provided with a slot 2101, and the positioning protrusion 231 and the slot 2101 are snap-fitted.

[0044] By providing the positioning protrusion 231 and the card slot 2101, the rotation of the sealing sleeve 230 can be limited in the circumferential direction, thereby preventing the sealing sleeve 230 from slightly rotating when the user uses the milk frother, affecting the sealing between the upper connector 200 and the positioning plate 140, improving the installation stability of the sealing sleeve 230, and ensuring the sealing effect of the sealing sleeve 230.

[0045] Reference Figure 5 and Figure 7 As shown, it can be understood that the outer wall of the upper connector 200 is provided with a plurality of copper bars 240 for connecting the motor 121 and the control component 300, and the plurality of copper bars 240 are arranged to protrude outward along the radial direction of the protrusion 210, and the pressure block 150 is provided with an avoidance portion 151, and the avoidance portion 151 is used to avoid the copper bars 240, and the avoidance portion 151 is a hole groove structure arranged on the pressure block 150 and matching the shape of the copper bars 240.

[0046] By providing the avoidance portion 151, when installing the pressing block 150, the user does not need to tilt the pressing block 150 to bypass the copper bus 240, but can directly press the pressing block 150 downward in the vertical direction to install the stud 141 into the hollow column 152. While improving the convenience of assembling the pressing block 150, the avoidance portion 151 can also play a role in foolproof positioning, reduce the installation direction of the pressing block 150, quickly align the stud 141 and the hollow column 152, and simplify the installation steps of the pressing block 150.

[0047] It can be understood that by setting a tortuous first waterproof channel and setting a sealing sleeve 230 to fill the first waterproof channel, the gap between the upper connector 200 and the positioning plate 140 can be effectively reduced, the moving path of water vapor impurities can be increased, and the sealing between the positioning plate 140 and the upper connector 200 can be greatly improved; the first waterproof channel, the second waterproof channel and the sealing cover 330 cooperate to greatly improve the overall sealing of the milk frother and enhance the protection effect of the internal mechanism of the milk frother.
