It can be understood that the third embodiment can be combined with the second embodiment, in this case, in order to increase the air pressure in the liquid receiving chamber 810 properly, the sidewall of the liquid receiving cup 640 is provided with a communication hole for communicating the liquid receiving chamber 810 with the pulverization chamber 210, when the liquid flows back from the liquid receiving chamber 810 to the extraction chamber 611, the air pump inflates the pulverization chamber 210, and a part of the gas in the pulverization chamber 210 flows into the liquid receiving cup 640 through the communication hole to increase the air pressure in the liquid receiving chamber 810, thereby increasing the pressure difference between the liquid receiving chamber 810 and the extraction chamber 611 properly.

Example four

In this embodiment, the tube connecting and discharging tube 612 is preferably an extension tube, the extension tube includes multiple sections of tube sections that are telescopically connected together, and the tube connecting and discharging tube 612 is higher than the positioning seat 630 when being contracted, so as to avoid blocking the placement of the extraction cup 610.

The other structures of the fourth embodiment are the same as those of the first embodiment, and are not described in detail here.

It is understood that the fourth embodiment can be combined with the second and third embodiments.

It is understood that the extension pipe 612 can also be a bellows type extension pipe.

In addition to the above preferred embodiments, the present invention has other embodiments, and those skilled in the art can make various changes and modifications according to the present invention without departing from the spirit of the present invention, which shall fall within the scope of the present invention defined in the appended claims.
