Handheld wet grinder

Abstract

A handheld wet grinder designed with water-discharging mechanism for wetting the powders. The wet grinder includes a main body and a water-discharging switch. A water incoming flow way is disposed in the main body and extends from the rear end of the main body to the front end thereof. A valve is installed in the flow way. The water-discharging switch is mounted on a circumference of the front end of the main body and connected with the valve. When shifting the water-discharging switch, the valve is driven to block or unblock the water incoming flow way so as to control water flow. The water incoming flow way is directly disposed in the main body without being exposed to outer side so that the flow way of water is protected from being damaged. In addition, the water-discharging switch is positioned at the front end of the main body so that a user can conveniently operate the water-discharging switch with the hand holding the main body without using the other hand.
