The first embodiment is as follows: as shown in fig. 1 to 6, a water squeezing device for a foam cotton head mop comprises a cleaning barrel 1 and a squeezing frame 2 arranged on the cleaning barrel 1, wherein the squeezing frame 2 is erected on the cleaning barrel 1, so that the squeezing frame 2 and the cleaning barrel 1 can be detachably connected, and the squeezing frame 2 is detached when cleaning is convenient. It should be noted that the squeezing frame 2 can also be formed integrally with the cleaning barrel 1, which can reduce the production cost.
Be equipped with on this crowded frame 2 and be used for carrying out crowded water mechanism of crowded water to foaming cotton head 622, crowded water mechanism is including being used for carrying out extruded base 3 to foaming cotton head 622 bottom surface and being used for carrying out extruded lateral part extrusion mechanism to foaming cotton head 622 both sides face, extrudees through trilateral (bottom surface and both sides face) and realizes better crowded dry effect. The base 3 is provided with water squeezing holes 31 which are uniformly distributed, and the water squeezing holes 31 are used for discharging squeezed water into the cleaning barrel 1 so as to realize better squeezing effect. It should be noted that the distribution, number, shape, or the like of the wringing holes 31 on the base 3 is not limited as long as the purpose of draining water can be achieved.
The lateral extrusion mechanism comprises a left extrusion block 41 and a right extrusion block 42 which are respectively arranged at two sides of the base 3, and a linkage component which is used for driving the left extrusion block 41 and the right extrusion block 42 to mutually approach or move away so as to extrude two side faces of the foaming cotton head 622. It should be noted that the distance between the left pressing block 41 and the right pressing block 42 is generally greater than or equal to or slightly less than the width of the foam head 622 so that the foam head 622 can be inserted into the wringing mechanism smoothly.
The linkage assembly comprises a sliding groove 21 which is arranged on the extrusion frame 2 and used for inserting and sliding the end parts of the left extrusion block 41 and the right extrusion block 42, wherein the sliding groove 21 is of a straight groove structure parallel to the upper surface of the base 3, the two ends of the left extrusion block 41 and the right extrusion block 42 are respectively inserted into the sliding groove 21 and can horizontally slide along the sliding groove 21, and meanwhile the sliding groove 21 connects the left extrusion block 41 and the right extrusion block 42 with the extrusion frame 2. It should be noted that the sliding slot 21 can also be a groove formed on the inner wall of the two ends of the extruding frame 2, and the extruding frame 2 and the sliding slot 21 are integrally formed at this time, so that the production cost is reduced. The tip of left extrusion piece 41 still sets up from base 3 lateral part to base 3 center tilt up's left chute 411, the tip of right extrusion piece 42 still sets up from base 3 lateral part to base 3 center tilt up, and with the right chute 421 of left chute 411 symmetry setting, the protruding left link shaft 32 that is equipped with left chute 411 phase-match in the left side of base 3, and slides in left chute 411, the protruding right link shaft 33 that is equipped with right chute 421 phase-match in the right side of base 3, and slides in right chute 421. This linkage subassembly realizes the linkage cooperation of base and extrusion piece through the cooperation of universal driving shaft and chute promptly, when pushing down the cotton head 622 of foaming and drive base 3 and move down, left universal driving shaft 32, right universal driving shaft 33 move down along with base 3, simultaneously because left universal driving shaft 32 is restricted to left chute 411, drive left extrusion piece 41 and move right when left universal driving shaft 32 moves down, the same reason, because right universal driving shaft 33 is restricted to right chute 421, drive right extrusion piece 42 and move left when right universal driving shaft 33 moves down, thereby make two extrusion pieces be close to each other, in order to extrude foaming cotton head 622 both sides face. It should be noted that the inclination directions of the left inclined groove 411 and the right inclined groove 421 can also be changed, that is, the end of the left squeezing block 41 is further provided with a left inclined groove 411 inclined downward from the side of the base 3 to the center of the base 3, and the end of the right squeezing block 42 is further provided with a right inclined groove 421 inclined downward from the side of the base 3 to the center of the base 3 and arranged symmetrically with the left inclined groove 411.
Preferably, the linkage structure further comprises a reset piece, the reset piece is a reset spring 5, and it should be noted that the reset piece can also be in other elastic structures. The return spring 5 is connected between the left pressing block 41 and the right pressing block 42, and preferably, the return spring 5 is located at the end of the left pressing block 41 and the right pressing block 42, so that the insertion of the foaming cotton head 622 into the wringing mechanism is not affected. When the foam cotton head 622 is pressed downwards, the left pressing block 41 and the right pressing block 42 are close to each other, and the return spring 5 is in a compressed state; when taking away the cotton head 622 of foaming left and right extrusion piece away from each other under this reset spring 5's effect, drive base 3 rebound through above-mentioned linkage structure simultaneously and resume to initial condition to use next time, make this wringing mechanism use more convenient. It should be noted that the return spring 5 can also be installed at other positions, for example, the return spring 5 can include a first return spring and a second return spring, the first return spring has one end connected to the left extrusion block 41 and the other end abutting against the left side wall of the extrusion frame 2, the second return spring has one end connected to the right extrusion block 42 and the other end abutting against the right side wall of the extrusion frame 2. When the foaming cotton head 622 is extruded downwards, the left extrusion block and the right extrusion block are close to each other, and the first return spring and the second return spring are in a stretching state; when the foaming cotton head 622 is taken away, the left extrusion block 41 and the right extrusion block 42 are far away from each other under the action of the first return spring and the second return spring, and simultaneously the base 3 is driven to move upwards to return to the initial state through the linkage structure.
In the second embodiment, as shown in fig. 4, the difference from the first embodiment lies in the structure of the chute 21, the chute 21 includes a left chute 211 into which the end of the left squeezing block 41 is inserted and which extends from the side of the base 3 to the center of the base 3, and a right chute 212 into which the end of the right squeezing block 42 is inserted and which extends from the side of the base 3 to the center of the base 3, and the left chute 211 is inclined downward toward the right chute 212, and the right chute 212 is inclined downward toward the left chute 211. The slide groove 21 is now in the form of an upwardly open V. Two ends of the left extrusion block 41 and the right extrusion block 42 are respectively inserted into the left sliding groove 211 and the right sliding groove 212 and can slide along the left sliding groove 211 and the right sliding groove 212 in an inclined manner. When the foam head 622 is pressed down to drive the base 3 to move downwards, the left linkage shaft 32 moves downwards along with the base 3, the left extrusion block 41 moves rightwards due to the limitation of the left chute 411, meanwhile, the left extrusion block 41 moves rightwards and downwards in an inclined mode due to the limitation of the left chute 211, and similarly, the right extrusion block 42 moves leftwards and downwards in an inclined mode, so that the left extrusion block 41 and the right extrusion block 42 are close to each other and move downwards along with the base 3 at the same time, and two side faces of the foam head 622 are extruded. Therefore, in the squeezing process of the foaming cotton head 622 pressed downwards, the side squeezing mechanism moves downwards along with the base, so that the upper and lower positions of the foaming head are unchanged, and the squeezing mechanism is more reasonable in structure and better in squeezing effect.
