[0023] The utility model will be described in detail below in combination with the drawings and examples.

[0024] The durable cleaning brush, as shown in Figure 1 , Figure 3 and Figure 4 , comprises a brush head 1 and a brush handle 2, a plurality of clusters of bristles 3 are fixedly connected to one side of the brush head 1, the bristles 3 increase the friction coefficient of the brush head 1, so that dirt on the object is cleaned down during the brushing process of the brush head 1 on the object, the brush handle 2 is fixedly connected to the side of the brush head 1 away from the bristles 3, a containing cavity is formed in the brush head 1, a reinforcing brush 4 is slidably connected to the containing cavity along the height direction of the containing cavity, the reinforcing brush 4 comprises a connecting plate and a hard-bristle brush fixedly connected below the connecting plate, the strength of the hard-bristle brush is more than twice the strength of the bristles 3, the hard-bristle brush can be made of animal bristles, hard plastic or other materials, the bristles 3 can be made of artificial fine fibers or other materials, a through slot 5 corresponding to each cluster of bristles 3 is formed in the bottom surface of the brush head 1, the bristles 3 of the reinforcing brush 4 are slidably connected in the through slot 5, the connecting plate slides in the height direction of the containing cavity, when cleaning surface stains or soft objects, the bristles 3 are directly used for cleaning, when cleaning deep stains, the connecting plate is pressed to drive the hard-bristle brush to slide downward, the hard-bristle brush extends out of the containing cavity from the through slot 5, the hardness of the bristles 3 is enhanced by the hard-bristle brush, the bristles 3 comprise an intermediate layer and a peripheral layer, the through slot 5 is arranged between the intermediate layer and the peripheral layer, so that the distribution of the hard-bristle brush in the bristles 3 is more uniform, the overall hardness of the bristles 3 is better supported, and the practicality of the cleaning brush is improved.

[0025] As shown in Figure 1 and Figures 4-6 , a cam 6 is rotatably connected in the containing cavity to drive the reinforcing brush 4 to slide in the containing cavity, the protruding part of the cam 6 is fixedly connected to one end of a traction rope 7 extending out of the brush handle 2, the traction rope 7 is detachably connected to the brush handle 2 through a fixed block 9, the top surface of the connecting plate abuts against the side wall of the protruding part of the cam 6, a torsional spring 8 is arranged at the rotatable connection between the cam 6 and the containing cavity, a through groove accommodating the traction rope 7 is formed in the brush handle 2, one end of the through groove is in communication with the containing cavity, and the other end is in communication with the side wall of the brush handle 2 away from the brush head 1, a spring 12 is fixedly connected between the bottom surface of the connecting plate and the inner bottom surface of the containing cavity, and the elasticity of the spring 12 is smaller than the elasticity of the torsional spring 8.

[0026] As shown in Figure 1 and Figure 4As shown, one end of the traction rope 7 is drawn out of the brush handle 2, which is convenient to control whether the reinforced brush 4 is extended at one end of the brush handle 2, so that the use of the cleaning brush is more practical. When the traction rope 7 is pulled out of the brush handle 2, the protruding part of the traction rope 7 pulls the cam 6 to rotate, and the torsional spring 8 fixedly connected with the rotation axis of the cam 6 is in a torsional state. The spring 12 exerts a pushing force on the connecting plate to drive the bristle brush to be stored in the accommodating cavity. Some objects with soft texture are brushed by the bristles 3. When stubborn stains need to be cleaned, the traction rope 7 only needs to be loosened. Because the elastic force of the torsional spring 8 is greater than that of the spring 12, after the external force acting on the torsional spring 8 is lost, the connecting plate is pushed to slide downward in the accommodating cavity, and the bristle brush is drawn out of the through slot, so that the hardness of the bristles 3 is increased. Therefore, only the traction rope 7 needs to be pulled to control the storage and extension of the reinforced brush 4.

[0027] As shown in Figure 2 , Figure 5 and Figure 6 , the fixed block 9 is fixedly connected to the outer peripheral wall of the traction rope 7. Symmetrically arranged fixed grooves are formed in the opposite side walls of the fixed block 9. A plurality of clamping grooves are formed in the brush handle 2 and communicate with the through slot. The clamping ball 10 is arranged in the clamping groove. The fixed block 9 is magnetically attracted to the clamping ball 10. The depth of the fixed groove is equal to the radius of the clamping ball 10. Two draw-out grooves are formed in the height direction of the brush handle 2 and communicate with the clamping groove. The suction block 11 is slidably connected in the draw-out groove. The suction block 11 is magnetically attracted to the clamping ball 10. The magnetic attraction force between the suction block 11 and the clamping ball 10 is greater than the magnetic attraction force between the fixed block 9 and the clamping groove.

[0028] As shown in Figure 2 , Figure 4 and Figure 6 , when the traction rope 7 pulls the reinforced brush 4 to be stored in the accommodating cavity, because the diameter of the clamping ball 10 is equal to the width of the clamping groove, when the fixed block 9 slides to the fixed groove and the clamping groove are communicated, the clamping ball 10 slides in the fixed groove under the magnetic attraction of the fixed block 9. The clamping groove limits the sliding of the clamping ball 10 along the length direction of the through slot, so that the clamping ball 10 can stably limit the sliding of the fixed block 9, avoiding the reinforced brush 4 from sliding out to affect the use of the cleaning brush during normal use of the cleaning brush. When the reinforced brush 4 needs to be slid out, the suction block 11 only needs to be pressed to insert into the clamping groove along the draw-out groove. Because the attraction force of the suction block 11 to the clamping ball 10 is relatively large, the suction block 11 pulls the clamping ball 10 away from the fixed block 9, so that the fixed block 9 loses the fixed effect on the traction rope 7, that is, the traction rope 7 loses the limitation on the cam 6.

[0029] As shown in Figure 3 , the side of the traction rope 7 away from the brush head 1 is fixedly connected with the expansion sheet 13. The cross-sectional area of the expansion sheet 13 is greater than that of the through slot, so that the traction rope 7 is prevented from sliding into the through slot when the traction rope 7 is loosened to drive the reinforced brush 4 to slide out, and the stable pulling of the traction rope 7 is ensured.

[0030] The above merely describes preferred embodiments of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiments. Any technical solution falling within the concept of the present application shall fall within the protection scope of the present application. It should be noted that, for ordinary skilled persons in the art, some improvements and refinements without departing from the principles of the present application shall also be considered as falling within the protection scope of the present application.
