Abstract: A liquid aerator including a first conduit for liquid communication therethrough, a second conduit for air communication therethrough, and, a third conduit configured for air communication between the first and second conduits; the first conduit including an internal shape configuration for generating a first pressure condition therein as liquid flows therethrough wherein air in the third conduit is drawn in to the first conduit in response to the first pressure condition generated in the first conduit, and, the second conduit including an internal shape configuration for generating a second pressure condition therein as air flows therethrough wherein air in the second conduit is forced in to the third conduit in response to the second pressure condition generated in the second conduit, whereby air flowing through the second conduit is transferred via the third conduit in to contact with the liquid flowing through the first conduit to aerate the liquid.

Abstract: This invention discloses a combined chopping board including a main chopping board and several additional chopping boards, the main chopping board and additional chopping boards are connected by means of a movable connection structure. The movable connection structure includes a hole stopper consisting of a head part and a neck part, this neck part is inserted in the through hole of the main chopping board across the through hole of the additional chopping board to fix the additional chopping board on the main chopping board; it can fulfill the need to use many chopping boards by the same user and can be selected according to the specific properties of the food, such as uncooked or cooked, the hardness of cutting through, and so on. The boards can be replaced and cleaned conveniently and the storage room can be saved with many chopping boards folding to an integral.
