Shape, the size relationship of the second seal member 161, the 3rd seal member 162 and the 4th seal member 163 and each self-corresponding mounting portion, inlet and maintaining part can arrange similar with the first seal member 160, do not repeat them here.

In the present embodiment, in order to prevent, due to maloperation, seal member is misplaced position, and then cause colour contamination, the position of black accomodating unit 120 pairs of maintaining parts and the length of seal member of present embodiment limit.First for the second seal member 161 and the second maintaining part 301, illustrating in present embodiment, how the length of seal member and the position of maintaining part are set.

As shown in Figure 7, the second length L of seal member 161 under natural extension state _b=L1+L2+L3, wherein L1 is the radius of the second fixed part 201 of the second seal member 161, and L2 is the length of the second connecting portion 191 of the second seal member 161, and L3 is the radius of the second body 181 of the second seal member 161.Representing with L when describing the overall length of seal member in this article, when mentioning the length L of the first seal member 160, second seal member 161, the 3rd seal member 162, the 4th seal member 163, being called L _a, L _b, L _c, L _d.Particularly, the length of the first seal member 160 is called L _a, the length of the second seal member 161 is called L _b, the length of the 3rd seal member 162 is called L _c, the length of the 4th seal member 163 is called L _d.

As shown in Figure 8, the position of the second maintaining part 301 can by following Parametric Representation:

The center of second maintaining part 301 of D1 corresponding to described second seal member 161 to the extension distance at the center of the second mounting portion 171 corresponding to described second seal member 161,

The center of second maintaining part 301 of D2 corresponding to described second seal member 161 to the extension distance at the center of the second inlet 211 corresponding to described second seal member 161,

The center of second maintaining part 301 of D3 corresponding to described second seal member 161 to the extension distance at the center of the adjacent next mounting portion (i.e. the 3rd mounting portion 172) of the second mounting portion 171 corresponding to described second seal member 161,

The center of second maintaining part 301 of D4 corresponding to described second seal member 161 is to the extension distance at the center of the adjacent next inlet (i.e. the 3rd inlet 212) of the second inlet 211 corresponding to described second seal member 161.

Should understand, the extension distance alleged herein surface referred to along the natural shape of black accomodating unit extends to the distance of another location naturally from a position, the extension distance implication all for this reason herein, hereafter repeats no more.

Further, in the present embodiment, the position of the second maintaining part 301 corresponding to described second seal member 161 meets the following conditions:

In the projection of horizontal plane, the second maintaining part 301 corresponding to described second seal member 161 between line A and line B, wherein,

The common tangential of the close front upper inlet (i.e. the first inlet 210) in the common tangential of second mounting portion 171 of line A corresponding to described second seal member 161 and the second inlet 211,

Line B is for through the second mounting portion 171 corresponding to described second seal member 161 and next mounting portion (namely, 3rd mounting portion 173) mid point and the line of mid point of the second inlet 211 corresponding to described second seal member 161 and next inlet (that is, the 3rd inlet 212).

In order to prevent because maloperation makes the second seal member be placed on the 3rd mounting portion 172 or the 3rd inlet 212, the second maintaining part 301 should be arranged between line A and line B as mentioned above, and the length L of the second seal member 161 _bshould meet the following conditions: L _b>=D1, L _b>=D2, L _b< D3, L _b< D4.Like this, due to the position of the second maintaining part 301 and the length L of the second seal member 161 _brestriction, when the second seal member 161 is fixed in the second maintaining part 301, in the second mounting portion 171 that second seal member 161 only can be placed into its correspondence or the second inlet 211, and can not be placed in the 3rd mounting portion 172 or the 3rd inlet 212, thus can prevent because the second seal member 161 being placed into the colour contamination caused in the 3rd mounting portion 172 or the 3rd inlet 212 by mistake.
