Description

Technical Field

[0001] This utility model relates to the field of cleaning tools, and in particular to a brush with a replaceable brush head. Background Technology

[0002] With technological advancements and improvements in living standards, users' functional needs for cleaning brushes are becoming increasingly diversified. However, current cleaning brush products on the market struggle to fully meet these needs, primarily due to the following issues:

[0003] I. Existing cleaning brushes generally adopt a structural design in which the bristles are vertically connected to the handle. Therefore, when cleaning special areas such as narrow gaps and corners, the operator is prone to awkward operating posture due to the limitation of the handle angle. In addition, the bristles at the far end of the brush body are difficult to reach the cleaning area, resulting in low bristle utilization.

[0004] Second, most mainstream cleaning brushes currently use an integrated structure where the brush head and handle are fixed together. When the brush head wears out due to long-term use, the entire brush needs to be scrapped, resulting in poor economic efficiency. Although some products with replaceable brush heads have emerged, they still suffer from complex structural designs and cumbersome brush head replacement procedures. Utility Model Content

The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Example 1

[0032] This embodiment provides a brush with a replaceable brush head, such as... Figures 1 to 6 As shown, the device includes a handle 1, a brush head 2, and a limiting member 3. The upper part of the brush head 2 is provided with a connecting groove 23, and the edge of the connecting groove 23 is provided with a locking groove 25. One end of the handle 1 is provided with a connecting protrusion 17 that matches the connecting groove 23. The connecting protrusion 17 is provided with a locking part 18 that matches the locking groove 25. The handle 1 is provided with a first limiting hole 15, and the brush head 2 is provided with a second limiting hole 24 that corresponds to and passes through the first limiting hole 15. The limiting member 3 passes through the first limiting hole 15 and into the second limiting hole 24 to lock the handle 1 and the brush head 2.

[0033] Specifically, the brush in this embodiment includes a detachably connected brush head 2 and handle 1, and the brush head 2 and handle 1 are locked together by a limiting member 3. The connecting protrusion 17 at the bottom of one end of the handle 1 has the same shape as the connecting groove 23 on the upper surface of the brush head 2. The connecting protrusion 17 can be placed inside the connecting groove 23, and the engaging groove 25 on the edge of the connecting groove 23 can engage the engaging part 18 on the edge of the connecting protrusion 17. The engaging part 18 is specifically a protruding strip extending outward from the connecting protrusion 17, thus forming an initial connection between the handle 1 and the brush head 2. After the handle 1 and brush head 2 are connected, the first limiting hole 15 and the second limiting hole 24 are aligned vertically. The limiting member 3 is inserted from the first limiting hole 15 to the bottom end within the second limiting hole 24 to achieve a secondary locking of the handle 1 and brush head 2, ensuring the connection is secure and preventing accidental detachment during use.

[0034] Preferably, the handle 1 includes a connector 12 and a grip portion 11. One end of the connector 12 is connected to the brush head 2, and the other end of the connector 12 is connected to the grip portion 11. The grip portion 11 extends upward relative to the axis of the connector 12, which conforms to the natural grip posture of the human body and ensures that the tail of the brush head 2 does not fail to contact the cleaning surface due to the restriction of the handle 1 during cleaning. The bottom of the connector 12 is provided with a connecting protrusion 17 that matches the connecting groove 23. The connector 12 is provided with a first limiting hole 15. When the connector 12 is connected to the brush head 2, the first limiting hole 15 and the second limiting hole 24 are vertically aligned and pass through each other, facilitating the insertion and connection of the limiting member 3.

[0035] Preferably, the upper part of the grip portion 11 near the connector 12 has a first arc-shaped recess 13 that conforms to the curve of the hand to improve user comfort. The surface of the first arc-shaped recess 13 has several anti-slip protrusions to increase the friction between the hand and the handle 1 and prevent slippage, thereby increasing the stability of the cleaning process. Meanwhile, three second arc-shaped recesses 16 are provided below the grip portion 11 to conform to other fingers, making the user's grip more secure and preventing the handle 1 from easily shifting when force is applied.

[0036] Preferably, the end of the handle 11 away from the connector 12 is provided with a connection hole 14, through which it can be directly hung on a hook or connected with a hanging rope for easy storage.

[0037] Preferably, the limiting member 3 includes a connecting platform 31 at the top and a limiting rod 33 at the bottom. The connecting platform 31 provides a force point for the insertion or removal of the limiting member 3. There are two limiting rods 33, which pass through the first limiting hole 15 and into the second limiting hole 24, so that the engaging part 18 of the handle 1 will not come out of the engaging groove 25 during the movement. The limiting rod 33 is provided with at least two limiting arcs 35, which are semicircles. The side wall of the first limiting hole 15 is provided with limiting dots that are adapted to the limiting arcs 35. The limiting dots are also semicircles. By fitting the limiting dots with the limiting arcs 35, the locking reliability of the limiting rod 33 can be enhanced, preventing the limiting rod 33 from accidentally falling off and ensuring the connection stability between the handle 1 and the brush head 2.

[0038] Preferably, the two sides of the connecting platform 31 extend outwards with operating parts 32 for fingers to grip, making it easier to insert and remove the limiting part 3. The outer surface of the operating part 32 is provided with anti-slip protrusions to increase the friction between the fingers and the operating part 32, so that the fingers can grip the operation firmly even when their hands are wet, thereby enhancing work efficiency.

[0039] Preferably, the bottom of the limiting rod 33 is provided with an outwardly extending limiting protrusion 34, and a limiting surface 19 adapted to the limiting protrusion 34 is provided inside the first limiting hole 15 and below the limiting dot. Specifically, the first limiting hole 15 includes two diameters from top to bottom. The upper diameter is narrower and matches the distance between the two limiting rods 33, while the lower diameter is wider. The distance between the limiting protrusions 34 is greater than the narrower upper diameter. Therefore, when the limiting rod 33 is pulled upward, it can only move to the connection point of the limiting surface 19, i.e., the diameter hole, so that the limiting member 3 does not need to be separated from the handle 1, thus avoiding loss.

[0040] Preferably, the brush head 2 includes a brush plate 21 and bristles (not shown in the figure). The sides of the brush plate 21 are wrapped with rubber protective rings 22, which can buffer the hardness of the edges of the brush plate 21 and prevent scratching the surface being cleaned. The lower surface of the brush plate 21 is covered with bristles for easy cleaning.

[0041] Preferably, the brush head 2 is triangular, which can accommodate more cleaning dead corners and improve cleaning efficiency.

[0042] A brief description of the brush head assembly and replacement process:

[0043] Pinch the operating element 32 with your fingers so that the limiting rod 33 is within the first limiting hole 15 and does not protrude beyond the surface of the connector 12. Push the connecting protrusion 17 at the bottom of the connector 12 little by little inward along the opening of the connecting groove 23. The engaging part 18 also engages within the engaging groove 25. After all the connecting protrusions 17 are within the connecting groove 23, pinch the operating element 32 with your fingers to move the limiting rod 33 into the second limiting hole 24. If you need to replace the brush head 2, pinch the operating element 32 upward and move the limiting element 3 away from the second limiting hole 24. Slowly pull the connecting protrusion 17 of the connector 12 outward away from the connecting groove 23, and then select a suitable brush head 2 for installation according to the above steps.

[0044] Example 2

[0045] like Figure 7 As shown, the difference between the brush in this embodiment and that in embodiment 1 is the shape of the brush head 2. The brush head 2 in this embodiment is strip-shaped, which can adapt to more different cleaning scenarios.

[0046] Although the embodiments of this utility model have been described in the specification, these embodiments are merely illustrative and should not limit the scope of protection of this utility model. Various omissions, substitutions, and modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
