Abstract

The invention discloses a flow control facilitating portable water color brush pen for students. An upper pen barrel, a reset spring, a fixing barrel, an installing sleeve and a pen cap are included. A first kneading block and a second kneading block penetrate through the side face of the upper pen barrel for installation, and connecting rods are arranged below the first kneading block and the second kneading block. The two ends of the reset spring are connected with the upper ends of the first kneading block and the second kneading block correspondingly. The lower ends of the connecting rods are connected with the top of a push rod. Sliding grooves are formed in the surface of the upper pen barrel, the upper end of a lower pen barrel penetrates through the sliding grooves, clamping ports are formed in the upper portion of the inner wall of the pen cap, check rings are arranged in the pen cap, and a silica gel pad is fixed to the outer side of the upper pen barrel. According to the flow control facilitating portable water color brush pen for students, when the ink amount is insufficient, only a capillary tube needs to be downwards pressed; and when the ink discharging amount is sufficient, only a pen body needs to be elevated, the larger the flowing-out ink amount is, the denser the color becomes, and the color shade is convenient to adjust.
