Foam Cotton Mop Head, a Mop Thereof, and a Manufacture Method Thereof

Abstract

A foamed cotton mop head has a mounting member (1) having a joint portion (11) mounted on a mounting plate (12) extending downward and a foamed cotton head (2) mounted on the mounting member (1); wherein, the mounting plate (12) is inserted downward into the top of the foamed cotton head (2) and attached to the foamed cotton head (2), forming a framework for the foamed cotton head (2). The whole foam cotton head (2) is partially supported by the mounting plate (12), so that the foamed cotton head (2) is kept at certain strength, not floppy, and difficult to shake and deform during mopping. The mopping operation becomes easier, and the hand feeling is better. During the water squeezing, it is ensured that the surface of the foamed cotton head are subjected to the squeezing force evenly and difficult to deform. In addition, it is easier for the foamed cotton head to pass through the elastic bayonet of the water squeezing frame.

DETAILED DESCRIPTION OF THE INVENTION

[0038] The present invention will be further described below in detail by embodiments with reference to the accompanying drawings.

Embodiment 1 of the Foamed Cotton Mop Head

[0039] FIGS. 1-3 show a preferred Embodiment 1 of the foamed cotton mop head of the present invention. The foamed cotton mop head comprises a mounting member 1 and a foamed cotton head 2 mounted on the mounting member 1. The mounting member 1 has a joint portion 11 mounted on a mounting plate 12 extending downward. The mounting plate 12 is inserted downward into the top of the foamed cotton head 2 and attached to the foamed cotton head 2, forming a framework for the foamed cotton head 2.

[0040] The mounting plate 12 is directly attached to the foam cotton head 2. The mounting plate 12 has a plurality of through holes 121 running transversely, or a plurality of recesses formed on the surface of the mounting plate 12.

[0041] The mounting plate 12 has a flange 122 extending transversely from the top of the mounting plate 12, the mounting plate 12 has a T-shaped cross-section; the joint portion 11, as an insertion joint, is connected to the middle of the flange 122 and extends upward from the top of the flange 122.

[0042] The joint portion 11 is hollow and oblate, and has an elastic clamping pin 111 on each of left and right sides.

[0043] The mounting member 1 having a joint portion 11 mounted on a mounting plate 12 extending downward; the mounting plate 12 is inserted downward into the top of the foamed cotton head 2 and attached to the foamed cotton head 2, forming a framework for the foamed cotton head 2. Accordingly, the whole foamed cotton head 2 is partially supported by the mounting plate 12, so that the foamed cotton head 2 is kept at certain strength, not floppy, and difficult to shake and deform during mopping. The mopping operation becomes easier, and the hand feeling is better. During the foamed cotton head 2 is squeezing, it is ensured that the surface of the foamed cotton head 2 are subjected to the squeezing force evenly and difficult to deform.

Embodiment 2 of the Foamed Cotton Mop Head

[0044] FIGS. 4 and 5 show a second embodiment of the foamed cotton mop head. The foamed cotton mop head of this embodiment differs from the above first embodiment in that, the foamed cotton head 2 has an insertion slot 21 extending downward from the top of the foamed cotton head 2; the mounting plate 12 is inserted into the insertion slot 21 and adhesively connected to the foamed cotton head 2;

[0045] Or, two sides of the foam cotton head 2 are folded upward from the bottom of the mounting portion 12 and extend to the surface of the mounting plate 12 to be adhesively connected with each other.

Embodiment of the Mop

[0046] FIGS. 6 and 7 show a preferred embodiment of a mop of the present invention. The mop comprises a mop rod 4 and the above said foamed cotton mop head. The bottom of the mop rod 4 is connected to the joint portion 11. A water squeezing frame 3 capable of moving in its axial direction is also attached to the mop rod 4. The water squeezing frame 3 has a U-shaped elastic bayonet 31. Two water squeezing rods 5 are respectively disposed on each side of the bottom of the elastic bayonet 31. By directly pushing the water squeezing frame 3, the foamed cotton head 2 passes between the water squeezing rods 5 on two sides to realize water squeezing.

[0047] The joint portion 11 is detachably inserted into and connected to the bottom of the mop rod 4 in a buckling manner.

[0048] The foam cotton head 2 has two strip-shaped slopes 22 on the top of the foam cotton head 2, which are respectively located on the two sides of the mounting portion 12. After the water squeezing frame 3 is moved down, the water squeezing rods 5 squeeze the foam cotton head 2 downward along the slopes 22.

[0049] In this embodiment, the up-down direction refers to the length direction of the mop rod 4, the left-right direction refers to the length direction of the foldable mop head 2, and the front-rear direction refers to the width direction of the foldable mop head 2.

[0050] The operation principle and working process of the mop is as below.

[0051] Water squeezing operation: the water squeezing frame 3 is held by one hand of a user, and the mop rod 4 is held by the other hand; the water squeezing frame 3 is pulled to move down relative to the mop rod 4; the water squeezing rods 5 on two sides of the water squeezing frame 3 squeeze downward the slopes 22 of the foamed cotton head 2; and the foamed cotton mop head passes upward between the water squeezing rods 5 on two sides to realize water squeezing.

[0052] There is no handle connecting rod structure between the squeezing frame 3 and the mop rod 4, so that the structure of the mop of the embodiment is simpler. The whole foam cotton head 2 is partially supported by the mounting plate 12, so that the foamed cotton head is kept at certain strength, not floppy, and difficult to shake and deform during mopping. The mopping operation becomes easier, and the hand feeling is better. During the water squeezing, it is ensured that the front and rear sides of the foamed cotton head 2 are subjected to the squeezing force evenly and difficult to deform. In addition, it is easier for the foamed cotton head 2 to pass through the elastic bayonet 31 of the water squeezing frame 3.

[0053] FIGS. 8-10 show a preferred embodiment of a manufacturing method of the foamed cotton mop head.

[0054] The manufacturing method comprises the following steps: [0055] step-1, manufacturing the above said mounting member 1; [0056] step-2, placing the mounting member 1 in a foaming die 6 as an insert, and pouring a polyurethane solution into the foaming die 6 and letting it stand, and then the polyurethane solution is foamed in the foaming die 6 to wrap the exterior of the mounting plate 12 of the mounting member 1 to form a foamed cotton head 2.

[0057] Finally, opening the foaming die, taking out the foamed cotton head, and removing the flash of the foamed cotton head 2.

[0058] In this embodiment, the foaming die 6 comprises an upper die 61 with an upper cavity 6b and a lower die 62 with a lower cavity 6a; the lower cavity 6a has a lower-half receiving chamber 6a1 for receiving the joint portion 11 and a lower foaming chamber 6a2 for foaming; the upper cavity 6b has an upper-half receiving chamber 6b1 for receiving the joint portion 11 and an upper foaming chamber 6b2 for foaming; after the upper die 61 and the lower die 62 are closed, the joint portion 11 is positioned within the space enclosed by the lower-half receiving chamber 6a1 and the upper-half receiving chamber 6b1, and the mounting plate 12 is located in the middle of the space enclosed by the lower foaming chamber 6a2 and the upper foaming chamber 6b2.

[0059] The detail operation of the foaming in the step-2 is as follows: pouring the polyurethane solution into the lower foaming chamber 6a2 and placing the mounting member 1 in the lower cavity 6a, and then closing the upper die 61 and letting it stand at last.

[0060] The mounting member is placed in the foaming die as an insert, and the polyurethane solution poured into the die is foamed in the die. The formed cotton head after foaming is wrapped with the mounting member to form one integrated mass, so that the foamed cotton head and the mounting member are attached very firmly, and the foamed cotton head is difficult to separate from the mounting member when in use. The conventional way of fixing the foamed cotton head to the mounting member by adhesion is discarded, and the use of glue is avoided. The foamed cotton mop head manufactured by this method is more environment-friendly, and avoids the damage to the human body caused by the use of glue. In addition, the manufacturing process is simpler, it is advantageous for mass production, and the cost is reduced.
