Description

Mop head

The present invention relates to a mop, and more particularly to a mop head for a mop.

For environmental cleaning, mops are often used as a cleaning tool for the floor. The mop generally includes a stick and a bundle of cotton cloth attached to the end of the stick. Using the absorption of water by cotton strips, you can wipe off the stains on the floor, or you can dry the water spilled on the floor.

Conventional mop heads are generally designed with through-and-through slots that are inserted through the slots for cleaning components (eg, cotton strips) from the underside and exposed on the upper side. The cotton strip is a soft material that is compressed to enter the slot and is caught in the slot by restoring the original volume. Further, in order to prevent the cotton strip from falling off, the cotton strip is additionally fixed on the upper side of the groove.

After the mop is used, dust and dirt will accumulate in the mop head, especially in the parts where the components are connected, as well as in the grooves and holes. Therefore, the mop usually needs to be carefully cleaned after use to be well preserved. .

In view of the above, the conventional mop head tends to accumulate dirt, and in particular, the exposed portion of the cotton strip on the upper side of the groove directly contacts the outside, and the position thereof is inconvenient to clean, so that it is difficult to clean and easy to breed bacteria. This will not only cause the cleaning effect of the mop to be worse, but also the use of the cotton strip to prevent the use of the cotton strip, reducing the life of the mop.

A cross-sectional view showing a mop head according to an embodiment of the present invention, and a fourth drawing showing a cross-sectional view of a mop head according to another embodiment of the present invention.

As shown, a mop head 100 in accordance with an embodiment of the present invention includes a mop head frame 1 and a cleaning member 2.

The mop head frame 1 is a circular frame in this embodiment, but may be a rectangular frame, a polygonal frame, or another frame of any shape. The mop head frame 1 has an upper surface 101 and a lower surface 102. The lower surface 102 of the mop head frame 1 is formed with a plurality of engaging recesses 11. In the present embodiment, the engaging recessed portion 11 is annularly distributed on the lower surface 102 of the mop head frame 1 along the outer edge shape of the mop head frame 1, but may be distributed in an array. The engagement recess 11 is preferably a circular recess having a bore that tapers, tapers, or remains constant from the lower surface 102 toward the upper surface 101. A plurality of convex bodies 12 are formed on the inner wall surface 110 of each of the engaging recesses 11. a majority between the upper surface 101 of the mop head frame 1 and each of the engaging recesses 11 Upper end perforations 13.

The cleaning member 2 may be a cotton strip or a cleaning member of other materials. A portion of the cleaning member 2 is engaged and received in the engagement recess 11 and fixed to the projection 12, and the remaining portion is exposed from the outside of the lower surface 102 for cleaning purposes. For example, in the present embodiment, the bent portion of the middle portion of the cleaning member 2 is engaged and received in the engaging recess 11, and the two end portions are extended from the lower surface 102 of the mop head frame 1. Alternatively, one end of the cleaning member 2 is engaged to engage the engagement recess 11 and the other end extends from the lower surface 102 of the mop head frame 1. The fixing between the mop head frame 1 and the cleaning member 2 is not required, and the cleaning member 2 can be engaged and fixed by the clamping force of the engaging recess 11 and the convex body 12 of the mop head frame 1 itself.

In detail, in the present embodiment, the engaging recess 11 is a through hole between the upper end portion 121 of the convex body 12 and the lower surface 102 of the mop head frame 1 for the cleaning member 2 to pass through. The cleaning member 2 is evenly disposed in the through hole and is received by the inner wall surface 110 of the engaging recess 11 and the convex body 12 to be received and fixed to the engaging recess 11 . In actual assembly, the cleaning member 2 can be compressed from the lower surface 102 of the mop head frame 1 into the through hole, and is engaged and received in the engaging recess 11 and fixed to the convex body 12 by restoring the original volume.

The plurality of convex bodies 12 are arranged at intervals on the inner wall surface 110 of the joint recess 11 and are arranged in a ring shape. The protrusions 12 may be disposed at equal intervals or at different intervals. When the spacers 12 are equally spaced, the cleaning member 2 in the engagement recess 11 may be uniformly held by the protrusions 12 in all directions to be relatively stable. Further, the convex body 12 may have a rough surface to increase the frictional force with the cleaning member 2, so that the cleaning member 2 is not easily released from the engaging recess 11. Also, each of the protrusions 12 has an upper end portion 121. A receiving recess 122 is defined between the upper end portion 121 of the convex body 12 and the inner wall surface 110 of the engaging recess portion 11. The accommodating recess 122 is for accommodating the cleaning member 2 so as to be engaged The cleaning member 2 in the recess 11 has a larger volume at the upper side portion than the lower side portion, and prevents the cleaning member 2 from slipping off.

The different configurations of the projections 12 can provide different fixing effects to the cleaning member 2. In the present embodiment, the convex body 12 has an extending portion 123 extending from the upper end portion 121 along the inner wall surface 110 of the engaging recess portion 11. The extending portion 123 may extend from the upper end portion 121 of the convex body 12 to the inner wall surface 110 of the engaging recess portion 11, and the convex body 12 has a reverse tapered shape as shown in FIG. Alternatively, the extending portion 123a may extend from the upper end portion 121 of the convex body 12a to the lower surface 102 of the mop head frame 1, and the convex body 12a has a cylindrical shape as shown in FIG. The extension length and inclination of the extending portion 123 affect the contact area between the convex body 12 and the cleaning member 2 and the direction of the contact force, thereby providing an appropriate frictional force to prevent the cleaning member 2 from coming loose.

In addition, the upper end portion 121 of the convex body 12 further has a tip portion 124. The tip 124 can be pointed upwards horizontally (as shown in Figure 3) or can be pointed upwards or upwards (as shown in Figure 4). The cleaning member 2 can be hooked and fixed by the tip portion 124 so that the cleaning member 2 cannot slide in the engaging recess portion 11. Further, the upper end portion 121 of the convex body 12 has a lead angle portion 125 at the same time. The lead-in portion 125 is for holding the cleaning member 2, and the clamping force to the cleaning member 2 is concentrated by its own beveled angle, so that the cleaning member 2 is tightly fixed in the engaging recess 11 and is not easily released.

The upper end perforations 13 correspond one to one to the convex body 12. In manufacturing, the convex body 12 can be formed on the inner wall surface 110 of the joint recess 11 by the space surrounded by the upper mold core and the lower mold core, and the upper end through hole 13 is formed in accordance with the passage space of the upper mold core. The shape of the upper end perforations 13 may vary depending on the design of the projections 12, which may be rectangular, circular, or any other shape. The aperture of the upper end perforations 13 may vary from a few mm to less than 1 mm. The aperture of the upper end perforation 13 is smaller than that of the engagement recess 11 so that dust and dirt are difficult to pass through the upper end perforation 13 without being accumulated in the engagement recess 11 but However, the engagement recess 11 can be vented to the outside.

With the above configuration, in the mop head 100 of the present invention, the joint portion of the cleaning member 2 and the mop head frame 1 does not expose the mop head frame 1, and the accumulation of dirt can be reduced. Moreover, proper aeration of the upper end perforations 13 allows the cleaning member 2 to be easily kept dry while extending its service life.
