Hereinafter, typical embodiments of the toilet brush according to the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to these drawings. Further, since the drawings are for conceptually explaining the present invention, dimensions, ratios, or numbers may be exaggerated or simplified as necessary to facilitate understanding.

As illustrated in FIG. 7, the toilet brush 1 is used for cleaning the toilet bowl 7, and is particularly suitable for cleaning the edge of the toilet bowl 7.
As shown in FIG. 1, the toilet brush 1 has a head 3 and a handle 5. Each component will be explained in detail below.

As shown in FIGS. 4 to 7, the head 3 is a sponge-like flexible porous member that is detachably attached to the handle 5. As shown in FIGS. As shown in FIGS. 2 and 3, the head 3 has a substantially rectangular parallelepiped shape having first to sixth surfaces. The head 3 is made of a foamed resin material such as polyurethane, but may be made of other materials.

The head 3 has a notch 33 or groove of a predetermined depth on a certain surface (first surface 31). The notch 33 is provided to receive the attachment portion 51 of the handle 5.
The depth of the notch 33 is approximately the same as the length of the attachment portion 51 of the handle 5, and is, for example, 5 cm to 10 cm (7 cm to 8 cm). The width of the notch 33 is approximately the same as or slightly wider than the width of the attachment portion 51, and is, for example, 2 cm to 5 cm.

For example, as shown in FIG. 2, a part of the surface (second surface 32) opposite to or facing the first surface 31 provided with the cut 33 is inclined with respect to the first surface 31. The angle α of the inclination shown in FIG. 3(C) is, for example, 30° to 60°.
The second surface 32 is formed, for example, by cutting a surface that is substantially parallel to the first surface 31. As a result, the tip on the second surface 32 side has an acute angle part and an obtuse angle part (for example, see FIGS. 2(A) and 2(B)), making it possible to follow the shapes of various parts of the toilet bowl. will improve.

The corners of the head 3 (corresponding to the vertices and sides of a rectangular parallelepiped) are generally rounded. The roundness is formed, for example, by cutting the corners.
In this embodiment, the front corner has a larger radius of curvature (that is, has a larger radius of curvature) than the rear corner (for example, see FIGS. 3D and 3E). Thereby, the head 3 has the ability to follow the edge of the toilet bowl 7 (to penetrate sufficiently deep into the edge).

Therefore, when the head 3 is inserted into the rim of the toilet bowl 7, the head 3 fits the rim of the toilet bowl 7 and can easily reach narrow edges (see FIG. 7).

One head 3 may be provided for each handle 5, or a plurality of heads 3 may be provided in a set (see FIG. 1).
In the latter case, the individual heads 3 may be colored in different colors. For example, by using different heads 3 depending on the nature of the detergent used (e.g. neutral, chlorinated, and alkaline detergents), consistent use of the head 3 is possible, and Mixing can be prevented.

Next, the handle 5 will be explained.
The handle 5 forms a rod. The handle 5 may be made of a resin material such as polypropylene, ABS resin, or polyethylene, or may be made of other materials such as wood or metal.

The handle 5 has a mounting portion 51 at its tip to which the head 3 is mounted. That is, the handle 5 is bent near the tip to form the attachment part 51. The attachment portion 51 is a frame or plate having a substantially U-shape, a substantially ring shape, or a substantially rectangular shape, and is inserted into the notch 33 of the head 3 .
Note that the bent portion of the handle 5 also serves as a bearing 512 that receives a shaft portion 522 of a holding portion 52, which will be described later (see FIG. 5).

The attachment portion 51 has a protrusion 511 that projects toward the inner surfaces 33A and 33B forming the notch 33 when inserted into the notch 33 (see, for example, FIG. 3(F) and FIG. 4). When the head 3 attempts to move toward the distal end of the attachment portion 51 (in other words, in the direction away from the attachment portion 51), the protrusion 511 bites into the inner surfaces 33A and 33B of the notch 33, and prevents further movement of the head 3 or from the attachment portion 51. It is a regulatory means to control the shedding of In this embodiment, the protrusion 511 is directed toward one of the inner surfaces 33A and 33B that constitute the notch 33, but the protrusion 511 may protrude toward both surfaces.
The protrusion 511 is inclined toward the proximal end of the attachment portion 51 . It is preferable that the angle β shown in FIG. 4(B) between the protrusion 511 and the attachment portion 51 is approximately 40° to 50°.

The handle 5 may have a holding part 52 that holds the attached head 3 between it and the mounting part 51 (see FIG. 6).
The holding portion 52 is rod-shaped, and is bent near the tip to form a pressing portion 521 . The bending of the holding portion 52 may be approximately the same as the bending of the handle 5.
A protrusion 523 protrudes toward the head 3 from the tip of the pressing portion 521 . The protrusion 523 bites into the surface of the head 3 attached to the attachment part 51 and restricts the movement of the head 3.

A shaft portion 522 protrudes from the bent portion of the holding portion 52 (see FIG. 5). The shaft portion 522 is received by a bearing 512 of the handle 5, thereby allowing the holding portion 52 to rotate relative to the handle 5. Therefore, by rotating the holding part 52 with respect to the handle 5, the head 3 can be held on the mounting part 51 or released from holding (see FIG. 6).

The handle 5 may have a recess 53 or a storage space for storing the holding portion 52 (see FIG. 7).
The recess 53 is provided along the handle 5. When the holding part 52 is rotated relative to the handle 5 and stored in the recess 53, the pressing part 521 and the mounting part 51 simultaneously hold the head 3 between them. Therefore, when the holding part 52 is housed in the recess 53 and the handle 5 and the holding part 52 are integrated, the head 3 is fixed to the attachment part 51.

Next, the procedure for using the toilet brush 1 will be explained.
Prepare the head 3 and handle 5. At this time, a plurality of heads 3 of different colors may be prepared.

The attachment part 51 of the handle 5 is inserted into the notch 33 of the head 3, and the head 3 is attached to the attachment part 51 (see FIG. 5). At this time, the head 3 may be selected or replaced depending on the detergent used.
Further, by rotating the holding part 52, the head 3 is held between the pressing part 521 of the holding part 52 and the attachment part 51 (see FIG. 6).
Thereby, the head 3 is fixed to the handle 5, and the toilet brush 1 is ready (see FIG. 7).

Next, the toilet bowl 7 is cleaned with the toilet brush 1.
First, spray detergent on head 3, apply it, and apply it. In other words, by applying the detergent to the head 3 instead of pouring it onto the toilet bowl 7, waste such as detergent scattering can be suppressed.

Then, the toilet bowl 7 is scrubbed with the toilet brush 1. At this time, the sharp tip of the head 3 enters the edge of the toilet bowl 7, so that the toilet bowl 7 can be cleaned from every corner (see FIG. 8).
If the toilet bowl 7 is to be further cleaned with a different type of detergent, the head 3 that is currently attached is removed from the handle 5 and another head 3 is attached. Alternatively, if the head 3 in use is damaged, only the head 3 can be replaced.

According to this embodiment, one toilet brush 1 can be used for all toilet bowls 7. That is, by applying detergent (liquid or foam) to the head 3 and using the head 3 to apply the detergent to the stains on the toilet bowl 7 to remove the stains, it is possible to suppress the detergent from scattering or dripping, and there is no wastage of detergent. .

Further, since the head 3 is replaceable, it is possible to reduce dust. In addition, the head 3 is replaceable, which contributes to reducing the amount of dust. In contrast, existing toilet brushes are one-piece with a handle 5, and when they get dirty, they must be thrown away, and the handle is long and difficult to dispose of.

Furthermore, by using heads 3 of different colors for different types of detergent, cleaning safety is increased. For example, heads 3 in three colors, white, black, and red, can be used for alkaline, neutral, and acidic detergents, respectively, so that they can be used depending on the detergent. This selective use avoids safety issues such as mixing acidic and alkaline detergents, which can be dangerous. Further, the head 3 can be visually identified, and generation of chlorine gas due to mixing of detergent can be more safely prevented.

Although the toilet brush that is one embodiment of the present invention has been described above, the present invention is not limited to these, and various design changes are possible as long as the technical idea of the present invention is included. All such design changes are included within the technical scope of the present invention.
