Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

Referring to fig. 1 to 6, a broom provided by the present application is now illustrated. The broom comprises a cleaning head 10, a broom handle 20, an elastic member 30 and a limiting member 40. The cleaning head 10 has a first cleaning direction and a second cleaning direction disposed opposite the first cleaning direction. With reference to the drawings, the positive X-axis direction is defined as a first cleaning direction, and the negative X-axis direction is defined as a second cleaning direction.

The sweeper handle 20 and the sweeper head 10 are capable of relative rotation, either rotationally or via other structural elements, with their axes of rotation perpendicular to the first sweeping direction and perpendicular to the axial direction of the sweeper handle 20. In the illustrated structure, the axis of rotation is in the Y-axis direction.

Two ends of the elastic piece 30 are respectively connected with the sweeping handle 20 and the sweeping head 10, and elastically bend when the sweeping handle 20 drives the sweeping head 10 to drag along the first sweeping direction (can bend and deform under the action of external force and can reset after the external force disappears); the limiting member 40 is connected to the sweeping handle 20 and limits the bending of the elastic member 30 when the sweeping handle 20 drives the sweeping head 10 to drag along the second sweeping direction.

When an operator holds the sweeping handle 20 to sweep along the first sweeping direction, the sweeping handle 20 is pushed along the first sweeping direction, the sweeping head 10 is subjected to the resistance of the ground, so that the elastic piece 30 is elastically bent, after the elastic piece 30 is bent, the sweeping head 10 rotates relative to the sweeping handle 20 (towards the negative direction of the X axis) and inclines relative to the ground, and when the sweeping handle slides, the resistance of the ground is reduced, so that the labor-saving effect is realized.

When an operator holds the sweeping handle 20 to sweep along the second sweeping direction, the limiting member 40 limits the elastic member 30 to bend and limit the rotation of the sweeping head 10, and at this time, the operator can apply a larger pushing force to the sweeping head 10 through the sweeping handle 20 to ensure the sweeping force.

By last, the broom that this embodiment provided, operating personnel make the broom handle 20 drive the cleaning head 10 and drag along first direction of cleaning when cleaning ground, realize laborsaving cleaning, and change the broom direction after rubbish is put together, make the broom handle 20 drive the cleaning head 10 and drag along the second direction of cleaning, and have great dynamics of cleaning to make things convenient for operating personnel's cleaning operation.

In this embodiment, the structure of the cleaning head 10 is not limited. The cleaning head 10 can be provided with bristles or brush plates of various specifications and materials according to actual requirements. In the configuration shown in fig. 1, the cleaning head 10 is provided with bristles (not shown). In the arrangement shown in figure 2, the cleaning head 10 is provided with a brush plate. In this embodiment, the structure of the elastic member 30 is not limited, and the elastic member 30 may be a spring plate, a spring, a torsion spring, an elastic band, or the like, which can realize the bending and the resetting of the cleaning head 30 relative to the cleaning handle 20.

Example one

Referring to fig. 1 and 2, the elastic member 30 is connected to the cleaning head 10 and the cleaning handle 20 at two ends thereof, and can be elastically bent. The cleaning head 10 and the cleaning handle 20 are provided with a gap. The cleaning head 10 and the cleaning handle 20 are connected through the elastic piece 30 and can rotate around the Y axis in the negative direction of the X axis, and at the moment, the elastic piece 30 is bent and deformed. In this process, the cleaning head 10 receives less resistance due to the deformation of the elastic member 30, so that labor-saving cleaning can be achieved. After the cleaning is completed, the elastic member 30 is restored to restore the cleaning head 10 and the cleaning handle 20.

The limiting part 40 is connected with the sweeping handle 20 and extends to one side of the sweeping head 10, the limiting part 40 is pressed against the sweeping head 10 when the sweeping handle 20 drives the sweeping head 10 to drag along the second sweeping direction, and the limiting part 40 avoids the bending of the elastic part 30 when the sweeping handle 20 drives the sweeping head 10 to drag along the first sweeping direction, and the limiting part enables the sweeping head 10 and the sweeping handle 20 to rotate relatively. The limiting member 40 is configured to limit the rotation of the cleaning head 10 in the positive direction of the X-axis, in other words, when the cleaning head 10 is dragged by the sweeping handle 20 in the second cleaning direction, the elastic member 30 cannot be elastically bent, and the cleaning head 10 receives a larger pushing force from the sweeping handle 20.

Preferably, the cleaning head 10 is provided with a connecting member 11, the limiting member 40 is connected to the cleaning handle 20 and sleeved outside the elastic member 30 and the connecting member 11, and the limiting member 40 has a limiting portion 41 which presses against the cleaning head 10 when the cleaning handle 20 drives the cleaning head 10 to drag along the second cleaning direction, and an avoiding groove 42 which avoids the bending of the elastic member 30 when the cleaning handle 20 drives the cleaning head 10 to drag along the first cleaning direction.

The stopper 40 has a half-cylindrical shape, and the escape groove 42 and the stopper 41 are located on both sides of the axis of the sweep handle 20. In the illustrated configuration, the stopper 41 is located forward of the axis (positive X-axis direction) and the escape groove 42 is located rearward of the axis (negative X-axis direction). The limiting part 41 extends to the outer side of the connecting piece 11 to limit the rotation of the connecting piece 11, and the groove 42 provides a space for the rotation of the sweeping handle 20 and the sweeping head 10. The limiting part 41 is positioned on one side of the positive direction of the X axis to limit the connecting piece 11 and the sweeping handle 20 to rotate towards the positive direction of the X axis, so that when the broom cleans in the second cleaning direction (negative direction of the X axis), the limiting part 40 presses against the connecting piece 11 to transmit the thrust from the sweeping handle 20 to the cleaning head 10. The avoiding groove 42 is positioned at one side of the X-axis negative direction to avoid the rotation of the cleaning head 10 in the X-axis negative direction, so that the sliding resistance of the cleaning head 10 is reduced when the broom works in the first cleaning direction. Therefore, the limiting and avoiding effects are realized through the shape design of the limiting part 40, and the structure is simplified.

The connecting piece 11 is arranged to be matched with the elastic piece 30 and the limiting part 41 conveniently. In other embodiments, the connecting member 11 may not be provided, and the limiting portion 41 directly presses the cleaning head 10.

The height of the connecting element 11 is not limited, in other words, the rotational connection point of the cleaning handle 20 and the cleaning head 10 (the position of the elastic element 30 in this embodiment) can be close to the cleaning head 10 or a distance away from the cleaning head 10.

In this embodiment, the elastic member 30 is a coil spring. The elastic member 30 is a coil spring, and is not elastic in the axial direction, but is a coil spring that is elastically bent by an external force (that can be restored after the external force is removed). In other embodiments, the elastic member 30 may also have other structures with bending elasticity, and is not limited herein.

In this embodiment, the limiting member 40 is connected to the sweep handle 20 in a snap-fit manner. The limiting member 40 and the sweeper handle 20 are independent parts, so that independent design and batch processing can be conveniently carried out according to functional requirements, and production cost is reduced. The limiting member 40 and the broom handle 20 are connected in a clamping manner, so that the assembly can be carried out without other tools, and the connection through other parts (compared with the screw connection) is not required, thereby facilitating the operation. In other embodiments, the position-limiting member 40 and the sweep handle 20 may be integrally disposed, and may be fixedly connected by welding, riveting, or detachably connected by screwing.

Referring to fig. 2, the sweeping handle 20 is provided with a clamping groove 201, the limiting member 40 further includes a connecting portion 43 connected to the limiting portion 41 and an elastic clamping block 44 disposed on the connecting portion 43, the connecting portion 43 is inserted into the sweeping handle 20, and the clamping block is clamped and connected to the clamping groove 201. The sweeper handle 20 is cylindrical. In the process that the connecting part 43 is inserted into the sweep handle 20, the elastic latch 44 abuts against the inner cylindrical surface of the sweep handle 20 and is elastically deformed until the connecting part 43 reaches the position of the slot 201, at this time, the elastic latch 44 is elastically restored to be in clamping connection with the slot 201, and the slot 201 limits the movement of the elastic latch 44 in the vertical direction, so that the clamping connection between the limiting part 40 and the sweep handle 20 is realized.

Preferably, there are two card slots 201 and the two card slots are arranged oppositely. Correspondingly, two elastic latch blocks 44 are arranged on two sides of the connecting portion 43.

In this embodiment, referring to fig. 2, the sweeping handle 20 is rotatably connected to the sweeping head 10 around the first sweeping direction. Specifically, the connecting member 11 includes a fixed block 111 connected to the cleaning head 10 and a transfer block 112 connected to the elastic member 30, and the fixed block 111 and the transfer block 112 are rotatably connected to each other in the first cleaning direction. It will be appreciated that there is a need for switching the cleaning mode during cleaning, for example, in the labor saving mode, when heavy objects to be cleaned are encountered, the broom needs to be switched to the mode in which the limiting member 40 resists bending of the elastic member 30 to clean heavy objects, however, the length direction of the broom head 10 facing the user is generally acute angle with the length direction of the broom handle 20, and the other side is generally obtuse angle during use of the broom. Based on the structure, in the process of switching the sweeping modes of the broom in the embodiment, only the sweeping handle needs to be rotated by 180 degrees, at the moment, the included angle between the length direction of the sweeping head 10 facing the user side and the length direction of the sweeping handle 20 is an obtuse angle, and then the included angle between the length direction of the sweeping head 10 facing the user side and the length direction of the sweeping handle 20 is adjusted to be an acute angle through the rotating mechanism, so that the sweeping modes can be switched, the sweeping operation is continued, and the operation is very convenient.

A first rotating shaft 113 is provided at the lower end of the transfer block 112, and the extending direction of the first rotating shaft 113 is the X-axis direction. The upper end of the fixed block 111 is provided with a first snap ring 114 matched with the rotating shaft, and the inner ring surface of the first snap ring 114 is in interference fit with the first rotating shaft 113, so that when the fixed block 111 is matched and connected with the transfer block 112, the fixed state is maintained relatively when no external force acts, and the broom can be cleaned conveniently. When the angle between the cleaning handle 20 and the cleaning head 10 needs to be adjusted, the operator applies an external force to the cleaning handle 20 to drive the cleaning handle to rotate, so that the first rotating shaft 113 and the first split ring 114 rotate relatively, the angle between the cleaning handle 20 and the cleaning head 10 is changed accordingly, and the adjusted relative position is maintained after the external force disappears.

Example two

Referring to fig. 4 to 6, the limiting member 40 is connected to the sweeping handle 20 and abuts against the sweeping head 10 to provide a pushing force to the sweeping head 10 to move in the second sweeping direction when the sweeping handle 20 drives the sweeping head 10 to drag along the second sweeping square;

the two ends of the elastic member 30 are respectively abutted against the cleaning head 10 and the cleaning handle 20 and elastically deformed when the cleaning head 10 is dragged along the first cleaning direction by the cleaning handle 20.

Referring to fig. 5, the limiting member 40 is located in front of the elastic member 30 (positive direction of X axis), and in a normal placement state, two ends of the elastic member 30 abut against the cleaning head 10 and the cleaning handle 20 to drive the cleaning handle 20 to have a tendency of rotating forward, so that the limiting member 40 abuts against the cleaning head 10. When the cleaning head 10 is pulled in the front direction of the X-axis (the first cleaning direction) by the handle 20, the elastic member 30 is compressed, and the cleaning head 10 and the handle 20 rotate relatively. The resistance of the cleaning head 10 is reduced, and thus the cleaning can be realized in a labor-saving manner. When the cleaning head 10 is dragged to the rear of the X-axis (the second cleaning direction) by the driving of the cleaning handle 20, the limiting member 40 abuts against the cleaning head 10, so that the operator can apply a greater pushing force to the cleaning head 10 through the cleaning handle 20, thereby ensuring the cleaning force of the cleaning head 10.

In this embodiment, the elastic member 30 is a torsion spring. Referring to fig. 5, the broom includes a connecting shaft 21 disposed on the broom handle 20 and extending along a direction perpendicular to the first cleaning direction, and a connecting frame 12 disposed on the cleaning head 10 and rotatably connected to the connecting shaft 21; the elastic member 30 is sleeved on the connecting shaft 21. In other embodiments, the connecting shaft 21 can be fixed on the connecting frame 12, and the sweeping handle 20 is rotatably connected with the connecting shaft 21 to realize the rotary connection of the sweeping handle 20 and the sweeping head 10. The axial direction of the connecting shaft 21 is the rotation axis direction of the sweeping handle 20 and the sweeping head 10.

Referring to fig. 5, the sweeping handle 20 is rotatably connected to the sweeping head 10 around the first sweeping direction. Specifically, the sweeping handle 20 comprises a handle body 22 and an adapter 23, the handle body 22 is rotatably connected with the adapter 23 around a first sweeping direction, and the connecting shaft 21 and the limiting piece 40 are arranged on the adapter 23. This arrangement enables the handle 22 to be rotated in a first cleaning direction towards and away from the cleaning head 10. It will be appreciated that there is a need for switching the cleaning mode during cleaning, for example, in the labor saving mode, when heavy objects to be cleaned are encountered, the broom needs to be switched to the mode in which the limiting member 40 resists bending of the elastic member 30 to clean heavy objects, however, the length direction of the broom head 10 facing the user is generally acute angle with the length direction of the broom handle 20, and the other side is generally obtuse angle during use of the broom. Based on the structure, in the process of switching the cleaning mode of the broom in the embodiment, only the rotating broom handle is required to rotate by 180 degrees, at the moment, the included angle between the length direction of the cleaning head 10 facing the user side and the length direction of the broom handle 20 is an obtuse angle, and then the included angle between the length direction of the cleaning head 10 facing the user side and the length direction of the broom handle 20 is adjusted to be an acute angle through the rotating mechanism, so that the labor-saving mode switching can be completed, the sweeping can be continued, and the operation is very convenient.

Referring to fig. 6, a second rotating shaft 24 is disposed at the lower end of the handle 22, and the extending direction of the second rotating shaft 24 is the X-axis direction. The upper end of the adaptor 23 is provided with a second split ring 25 which is matched with the second rotating shaft 24, and the inner ring surface of the second split ring 25 is in interference fit with the second rotating shaft 24, so that when the handle body 22 is matched and connected with the adaptor 23, the handle body is maintained in a relatively fixed state under the action of no external force, and the broom can be cleaned conveniently. When the angle between the cleaning handle 20 and the cleaning head 10 needs to be adjusted, an operator applies an external force to the handle body 22 to drive the handle body to rotate, so that the rotating shaft and the split ring rotate relatively, the angle between the handle body 22 and the cleaning head 10 is changed along with the rotation, and the adjusted relative position is maintained after the external force disappears.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modification, equivalent replacement or improvement made within the spirit and principle of the present invention should be included in the present invention.
