Embodiments of the present invention provide an outfeed brush head for use with a feeding assembly (not shown) for feeding paint 500 (see fig. 4, 5, 14 and 15).
As shown in fig. 1 to 6, the discharging brush head includes a brush head seat 100, a brush head cover 200 and a valve 300. The brush head seat 100 is provided with a brush seat inlet 101a matching with the feeding assembly, and a brush seat outlet 101b communicating with the brush seat inlet 101a, so that when the feeding assembly feeds to the discharging brush head, the coating 500 enters from the brush seat inlet 101a, wherein the coating 500 may be paint or latex. The brush head cover 200 is fixed to the brush head base 100, and includes a discharge head 210 and a connection pipe 220 connecting the brush head base 100 and the discharge head 210. The discharging head 210 is provided with a discharging port 201 communicated with the connecting pipe 220 through a pipeline, and the discharging port 201 is arranged at the end part of the discharging head 210 far away from the brush head seat 100. The connecting pipe 220 includes an extending portion 220a connected to the brush head base 100 and extending along the opening direction of the brush head base outlet 101b and having elastic recovery, and a pressing portion 220b connected to a pipe end of the extending portion 220a away from the brush head base 100 and extending inward, the pressing portion 220b has a movement tendency toward the valve 300 under the action of the elastic recovery force of the extending portion 220a, the valve 300 is disposed between the pressing portion 220b and the brush head base 100, the pressing portion 220b is in sealing contact with the valve 300 when the valve 300 is subjected to an external force in the opening direction of the brush head base outlet 101b, and the sealing contact with the valve 300 is released when the discharge head 210 is subjected to an external force perpendicular to the opening direction of the brush head base outlet 101 b. In the present embodiment, the discharging head 210 is connected to the inner edge of the pressing portion 220b and extends in a direction away from the brush head seat 100.
Based on the above structure, because the extension part 220a has elastic recovery, the discharging brush head can have three states according to the stress condition of the extension part 220a, which are as follows:
as shown in fig. 2, the discharging brush head is in a free state, that is, the feeding assembly does not feed the paint 500 to the discharging brush head, the pressing portion 220b has a movement tendency toward the valve 300 under the elastic restoring force of the extending portion 220a, the pressing portion 220b presses the valve 300 to the brush head seat 100 and blocks the brush seat outlet 101b, so as to prevent the paint 500 from flowing out of the brush seat outlet 101 b;
as shown in fig. 4, the discharging brush head is in a static pressurized state, that is, the feeding assembly feeds the paint 500 to the discharging brush head, wherein in order to feed the paint 500 to the discharging brush head, a certain pressure needs to be applied to the paint 500 to feed the paint 500 to the discharging brush head, and the pressure applied to the paint 500 by the feeding assembly is transmitted to the valve 300, so that the valve 300 receives an external force in the opening direction of the brush holder outlet 101b to offset the elastic restoring force of a part of the extending portion 220a, so that the valve 300 is separated from the brush holder 100, and at this time, since the bonding between the pressing portion 220b and the valve 300 is still tight, the paint 500 still cannot smoothly overflow to the discharging head 210;
as shown in fig. 5, the discharging brush head is in a working state, that is, on the basis that the discharging brush head is in a static pressurized state, the discharging brush head collides with the surface 600 to be brushed and is dragged, at this time, the discharging brush head 210 will generate friction with the working surface, the working surface will generate a lateral acting force on the discharging brush head 210, and since the extending portion 220a has elastic recovery, the lateral acting force will make the extending portion 220a generate inclined deformation, and in the process that the extending portion 220a generates deformation, a gap will appear between the pressing portion 220b and the valve 300, the coating 500 can overflow to the discharging brush head 210 from the gap, and the discharging brush head drags back and forth on the working surface ceaselessly, and the coating 500 can overflow to the discharging brush head 210 continuously, thereby realizing continuous feeding.
Based on the above, through brush head seat 100, brush head cover 200 and valve 300 setting, ejection of compact brush head can receive the exogenic action of perpendicular to brush holder export 101b opening direction when ejection of compact head 210, just the ejection of compact brush head just ejection of compact when carrying out the coating operation promptly, the ejection of compact time of ejection of compact brush head can adapt to the operation time of applying paint with a brush of ejection of compact brush head, and can not be at the ejection of compact of action time of non-applying paint with a brush, and for prior art, this ejection of compact brush head has simple structure, and the manufacturing of being convenient for, convenient maintenance. In addition, because the pressing part 220b is released from sealing engagement with the valve 300 when the discharging head 210 is subjected to an external force perpendicular to the opening direction of the brush holder outlet 101b, the acting force applied to the coating 500 only needs to be slightly greater than the force required to make the coating 500 reach the brush holder outlet 101b, the required pressing force is small, and thus, the feeding assembly also only needs to adopt small power to convey the coating 500.
