Specific implementation mode
Writing brush embodiment
As shown in Figure 1, the writing brush that the present embodiment Portable student handwriting class uses, has the writing brush head 1 being sequentially connected, connects
Fitting 2, ink storage pipe 3 and penholder 5, writing brush head 1 are fixed by connector 2,3 both ends of ink storage pipe respectively with the connector 2 and
Penholder 5 is connected through a screw thread, and realizes that the assembly of writing brush is fixed.Ink storage pipe 3 can also pass through inserting mode with connector 2 and penholder 5
It is fixed.
As shown in Figure 1 and Figure 2, in the present embodiment, ink storage pipe 3 has the ink storage chamber 6 for storing prepared Chinese ink, the bottom of ink storage chamber 6
End is equipped with ink outlet port 8, and ink outlet port 8 is provided in round in this example, and ink outlet port is aperture, and the internal orifice dimension of ink outlet port 8 is 0.5mm-
1.0mm so that prepared Chinese ink is not oozed from ink outlet port under intake valve close closed state, is provided between ink outlet port 8 and writing brush head 1 for inciting somebody to action
The prepared Chinese ink that ink outlet port 8 oozes is inducted into the conduit 7 of writing brush head 1.As shown in Figure 1, the conduit 7 is set in connector 2, conduit 7
1 tail portion of writing brush head is inserted into lower end, and 7 upper end of conduit is equipped with the horn mouth extended out, and 8 lower end of ink outlet port is inserted into the horn mouth, it is ensured that
The prepared Chinese ink to drip can smoothly enter into conduit 7.Certainly, ink outlet port lower end is flushed with horn mouth, or same positioned at bell-mouthed top
Sample is also feasible.There are gap, interstice coverage 1.0mm-3.0mm between conduit 7 and ink outlet port 8.The top of ink storage pipe 3 is set
It is the intake valve 4 closed to be equipped with the normality being connected with ink storage chamber 6, and then corresponding be provided with is used to open the intake valve 4 and makes penholder 5
Air enters the switching mechanism of ink storage chamber 6.
Diversified forms can be used in the ink storage pipe intake valve and switching mechanism of the utility model writing brush.In the present embodiment, into
Air valve 4 use taper valve arrangement, have valve body 12, valve seat 13, valve opening, the valve rod 14 in valve opening, on valve rod 14
Valve head and the resetting spring 15 being sheathed on valve rod, valve opening carry bellmouth, and valve head is resisted from inside under the action of the spring
Bellmouth realizes the closing of intake valve.Corresponding, in this example, there is switching mechanism the vertically arranged promotion that is used for open intake valve
