Abstract

A nozzle head cleaning module including a base housing having a main slope; a main carrier received in the base housing, a sub-carrier received in the main carrier and has a cover protruding upwardly, and an interference structure is provided. A set of one or more horizontal planes is formed on the main slope. A set of one or more main slide pins contacting with the main slope protrudes from the main carrier including a sub-slope, and the main carrier is moved along the main slope. When resting on the main slope, the main slide pin contacts with the main slope by multiple contact points. When resting on the horizontal plane, the main slide pin contacts with the horizontal plane by multiple contact points. The horizontal plane support main slide pin to maintain the cover in a raised position when the main slide pin is located thereon.

First claim

What is claimed is:

1 . A nozzle head cleaning module, comprising:
a base housing including a main slope, a set of one or more horizontal planes being formed on a portion of the main slope; a main carrier received in the base housing, a scraper protruding upwardly from the main carrier, a set of one or more main slide pins in contact with the main slope protruding from the main carrier, the main carrier including a sub-slope, the main carrier being lifted or lowered obliquely along the main slope with respect to the base housing so as to lift or lower the scraper, wherein when disposed on the main slope, the set of one or more main slide pins is in contact with the main slope along a longitudinal direction of the main slope by multiple contact points; and when disposed on the set of one or more horizontal planes, the set of one or more main slide pins is in contact with the set of one or more horizontal planes by multiple contact points; a sub-carrier, the sub-carrier being accommodated in the main carrier, the movement of the main carrier moving the sub-carrier at the same time, a cover protruding upwardly being arranged on the sub-carrier, at least a portion of the sub-carrier being in contact with the sub-slope; and an interference structure arranged corresponding to the sub-carrier, wherein when the interference structure is in contact with the sub-carrier while the sub-carrier is moving, the interference structure pushes the sub-carrier to move along the sub-slope with respect to the main carrier, and the cover thereby ascends; and when the set of one or more main slide pins is moved onto the set of one or more horizontal planes, the set of one or more horizontal planes support the set of one or more main slide pins to maintain the cover in a raised position.

2 . The nozzle head cleaning module according to claim 1 , wherein the interference structure is disposed inside the base housing.

3 . The nozzle head cleaning module according to claim 1 , further comprising a driving assembly, the driving assembly being connected to the main carrier to move the main carrier.

4 . The nozzle head cleaning module according to claim 3 , wherein the driving assembly includes a motor and a gear set, and the gear set is operatively associated with the motor and the main carrier.

5 . The nozzle head cleaning module according to claim 4 , wherein the main carrier includes a rack, and the rack meshes with the gear set.

6 . The nozzle head cleaning module according to claim 5 , wherein the rack is parallel to the main slope.

7 . The nozzle head cleaning module according to claim 1 , wherein the main slope and the sub-slope are inclined in opposite directions.

8 . The nozzle head cleaning module according to claim 1 , wherein an upper end of the main slope is arranged corresponding to the interference assembly.

9 . The nozzle head cleaning module according to claim 1 , wherein a sub-slide pin in contact with the sub-slope protrudes from the sub-carrier.

10 . The nozzle head cleaning module according to claim 1 , the scraper is ascendable to protrude out of a top surface of the base housing.

11 . The nozzle head cleaning module according to claim 1 , the cover is ascendable to protrude out of a top surface of the base housing.

12 . The nozzle head cleaning module according to claim 1 , wherein the set of one or more main slide pins includes multiple cylindrical main slide pins, the set of one or more horizontal planes includes multiple horizontal planes corresponding to the main slide pins respectively; when the set of main slide pins is disposed on the main slope, each of the main slide pins is in contact with the main slope; and when the set of one or more main slide pins is disposed on the horizontal planes, the main slide pins are in contact with the horizontal planes respectively.

13 . The nozzle head cleaning module according to claim 1 , wherein the set of one or more main slide pins includes a single main slide pin which is a diamond-shaped pillar, and the main slide pin includes a first support plane and a second support plane inclined to each other, the set of one or more horizontal planes includes a single horizontal plane corresponding to the main slide pin; when the main slide pin is disposed on the main slope, the first support plane is in contact with the main slope; and when the set of one or more main slide pins is disposed on the horizontal plane, the second support plane is in contact with the horizontal plane.
