Abstract: A calf massage module includes: at least one movable shaft inserted into a spring so as to move forward or rearward by the compression and expansion of the spring; a massage module housing having a movable shaft guide part for guiding the movement of the movable shaft; and a moving housing inserted into the massage module housing according to the movement of the movable shaft.

Abstract: Disclosed is a side stream flow-type reverse osmosis membrane filter with an increased purified water recovery rate. The filter comprises: a filter housing with a raw water port, a purified water port, and a concentrated water port; an RO filter to purify raw water, thereby sending purified water to an inside thereof and discharging concentrated water, which is filtered out; a central tube for collecting the purified water; a raw water pipe arranged in the central tube and provided with a raw water flow channel in a center portion thereof, with a purified water flow channel formed between the raw water pipe and the central tube; and a raw water distributor for supplying supply a portion of raw water to the upper end of the RO filter and a portion of the raw water the lower end of the RO filter and supplying the purified water to the purified water port.

Abstract: Disclosed is a reverse osmosis membrane filter for increasing a recovery rate of purified water by extending a residence time of raw water on a reverse osmosis sheet. The reverse osmosis membrane filter having a fluid channel formed on a side surface thereof, according to the present invention, comprises: a central tube having a purified water inflow hole radially formed therein; a guide tube that is coupled to the outside of the central tube and has a raw water moving passage formed in the longitudinal direction thereof and a raw water outflow hole radially formed therein which communicates with the raw water moving passage; a reverse osmosis membrane sheet that filters a foreign substance contained in raw water and supplies the filtered purified water into the central tube through the purified water inflow hole; and a filter housing that accommodates the reverse osmosis membrane sheet.

Abstract: Disclosed is a device which prevents leakage by automatically shutting off flow of incoming tap water using a plunger as a check valve when a compressed pulp body expands due to fluid leaking from a water purifier or under a sink.
