Description

Mop head

This creation relates to a mop head, and more particularly to a mop head having a topless engagement recess that is highly engageable with the cleaning member.

Recently, flat mop heads have become popular, and their advantages are low height, deep corners that are difficult to clean, and easy to rotate and fold, so the cleaning effect, self-cleaning and storage effects are affirmed. However, the joining of the cleaning member (i.e., the cotton strip) to the flat mop head requires a different engagement than the conventional bundle mop.

Conventionally, such a flat mop head is provided with an engaging perforation (ie, an engaging recess having an upper hole) through which the mop head frame is vertically penetrated, and a part of the cleaning member (for example, a cotton strip) is punched with the punch a punching portion as a cleaning member at the top of the abutting portion, wherein the punching portion serves as a front end of the cleaning member, and the cleaning member is flushed from the lower opening of the engaging perforation through the engaging perforation until the punching portion is exposed a hole, in detail, the cleaning member is pressed to enter the lower side opening of the engaging perforation with the punching portion as a front end and continue to pass over the engaging portion in the engaging perforation to be on the upper side of the engaging perforation An outer portion of the opening (upper hole) is exposed, and the exposed portion of the cleaning member is formed by recombining the frictional force with the upper opening and the friction between the locking portion and the cleaning member by restoring the original volume Engaging, the exposed portion of the cleaning member exposed to the upper hole is pulled back, so that the punching portion of the cleaning member is further retained in the upper hole of the engaging through hole, and the cleaning member and the locking portion are further engaged Friction between The cleaning member to the clamping engagement perforations. Further, it is a conventional practice to separately fix the punched portion of the upper opening (upper hole) exposed to the joint through hole.

However, such a flat mop head which is provided with a perforation in the upper and lower sides of the mop head frame has its disadvantages after use, and dust, dirt or hair is accumulated in the mop head, especially in the exposed punching portion. The gap between the upper side opening and the upper side opening is more likely to be contaminated, which is not only unsightly, but also the dust, dirt or hair is released from the gap due to the cleaning process, or is caught by falling when the mop head is rotated and cleaned. The rotating members of the sink will cause inconvenience in use.

Therefore, there is known a design in which a lower opening is provided in a flat mop head frame without providing an upper recess, that is, an engaging recess having no upper hole. However, the conventional mop head frame of the above-described non-upper hole engaging recess has a problem that it is not easy to be secure when the cleaning member is attached. The reason is that when the punch punches the cleaning member, the cleaning member is required to be engaged in the engaging portion of the engaging recess, and at the same time, the punch does not damage the engaging portion, so that the cleaning member can be surely engaged. In the case of the engaging recess, the punch is withdrawn from the engaging recess, causing a dilemma. This conventional topless mop head frame does not solve this problem.

Therefore, the object of the present invention is to provide a mop head which can be securely provided only in the flat mop head frame without the lower opening engagement recess (ie, the upper recessed engagement recess) Engaging the cleaning member.

The technical means adopted by the present invention for solving the problems of the prior art provides a mop head comprising: a mop head frame which is injection molded by a mold covering, the mold having a plurality of convex portions, by a majority a plurality of engaging recesses formed on the lower surface of the mop head frame, each of the engaging recesses including a lower opening, a closed upper top portion, a side wall and a narrow connecting portion, the closed top portion being the mop The upper surface of the head frame is closed and closed. The side wall is between the lower opening and the closed top. The narrow portion includes a first protruding member group, a first wearing portion, a second protruding member group and a second portion. Wearing a hollow portion, and the narrow portion is the first protruding member group, the first wearing portion, the second protruding member group, and the second wearing portion And the second protruding member group and the second protruding member group extend from the side wall toward a longitudinal axis of the engaging recess by the injection molding, the first wearing portion is Adjacent to a ring side of the first protruding piece set and a ring side of the second protruding piece set, a wear between the ring side of the first protruding piece set and the ring side of the second protruding piece set An empty space, the second airtight portion is adjacent to the other ring side of the first protruding member group and the other ring side of the second protruding member group, and is the other ring side of the first protruding member group and the first a through space between the other ring side of the two convex member groups, the first hollow portion is opposite to the second hollow portion, and an accommodating concave portion is formed between the closed upper top portion and the narrow connecting portion Wherein, after the injection molding, the protruding portion abuts and passes through the first protruding member group and the second protruding member group to forcibly release the film from the engaging concave portion; and a cleaning member has a punching portion, a plug portion and an uninserted portion, the top portion of the punching portion is passed by a word punch and the first punch portion is passed through the first through portion in a lateral width and a longitudinal thickness Inserting the punching portion and the inserting portion into the receiving recessed portion, and then the reverse punching back through the first through-empting portion and the second through-opening portion The engagement recess is extracted.

In an embodiment of the present invention, a mop head is provided, wherein a first wearing width of the first hollow portion on the side wall and a second wearing width of the second hollow portion in the side wall are greater than The width of the space between the angular protrusions of the first protrusion group and the second protrusion group.

In an embodiment of the present invention, there is provided a mop head, wherein the first protrusion member is a plurality of adjacent angular protrusions, each of the angle protrusions is disposed on the side wall of the adjacent ring, and the second protrusion group It is a plurality of adjacent angular protrusions, and each of the angular protrusions is disposed adjacent to the side wall.

In an embodiment of the present invention, there is provided a mop head, the first hollow portion being parallel to the second through-hole portion on a radial side of the lower opening at a radial side of the lower opening .

In an embodiment of the present invention, there is provided a mop head, the first male member set being a continuous convex body having a continuous thickness in a radial direction of the lower opening, the second male member set being at the lower opening A continuous convex body having a continuous thickness in the radial direction.

In an embodiment of the present invention, a mop head is provided, the lower opening having a buffer distance between the first protrusion group and the second protrusion group in the axial direction of the lower opening.

The mop head of the present invention has the following effects: as shown in Fig. 2, the cleaning member 2 is engaged in the narrow portion 15 of the engaging recess 11 while the punch does not break the narrow portion 15 to make the cleaning member 2 is that the punch is withdrawn from the engagement recess 11 in the case where the engagement recess 11 is surely engaged. As shown in Fig. 6, the present invention allows the punch P to positively punch the cleaning member 2 into the engaging recess 11 as long as a relatively gentle force is applied to the punch P, and also for the punch. The head P can withdraw the punch P from the engaging recess 11 without exerting a relatively gentle force, without affecting the engagement condition of the cleaning member 2 and the narrow joint portion 15.
