Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a bending rod structure and cleaning equipment. Background Art

[0002] With the rapid development of society, people's living standards are constantly improving, and more and more intelligent products are being applied to our daily lives. In the cleaning work of the home, many cleaning equipment have also appeared, including sweepers, cleaning equipment, floor scrubbers, etc. Existing handheld cleaning equipment or floor scrubbers require manual control. The advantage is that users can directly take them to the place that needs to be cleaned according to their needs; the disadvantage is that due to the long handle, when it is necessary to clean the bottom of the bed, etc., the human-machine operation angle is small. When it is necessary to clean the space under the sofa, bed cabinet furniture and desk, the user needs to bend down repeatedly or even squat down, which is inconvenient in a small space, seriously affecting the usability and user experience. At the same time, the existing handheld cleaning equipment or floor scrubbers can only be hung on the wall when storing and charging, which is a single method. Utility Model Content

In some embodiments, on the rotation path of the second bending rod 200 and the support rod 400, the second bending rod 200 is provided with a second limiting portion 201, and the support rod 400 is provided with a second limiting matching portion 402, and when the second bending rod 200 is rotated relative to the support rod 400 until the second limiting portion 201 and the second limiting matching portion 402 are abutted against each other, the second bending rod 200 and the support rod 400 form a 90° angle.In some embodiments, the second limiting portion 201 is disposed on the first rotating shaft 103 and is formed by the outer wall of the second rotating shaft 203 protruding outward; the second limiting matching portion 402 includes a second stroke groove 402a formed by the inner wall portion of the second rotating hole 404 being recessed inward, and the second limiting portion 201 can move in the second stroke groove 402a, wherein the angle between the two ends of the second stroke groove 402a and the line connecting the center of the second rotating hole 404 is 90°, so as to limit the rotation stroke between the second bending rod 200 and the second supporting rod 400 to 0-90°. In some embodiments, the first stroke groove 401a and the second stroke groove 402a are disposed on the side where the first rotating hole 403 and the second rotating hole 404 are close to each other; then the first limiting portion 101 is disposed on the side of the first rotating shaft 103 close to the second rotating shaft 203, and the second limiting portion 201 is disposed on the side of the second rotating shaft 203 close to the first rotating shaft 103.

[0077] In some embodiments, the locking mechanism 500 includes a locking member 501 and a locking fitting member 502, wherein the first bending rod 100 is provided with the locking member 501 on one side between the two support rods 400, and correspondingly, the second bending rod 200 is provided with the locking fitting member 502 on the same side. With the above scheme, when the locking member 501 and the locking fitting member 502 are in a locked state, the first bending rod 100 and the second bending rod 200 are locked on the same axis; after the locking member 501 and the locking fitting member 502 are in an unlocked state, the first bending rod 100 can be operated to rotate and can be folded 180° in the forward direction, which is easy to operate. The cleaning structure 700 in the bent state can easily reach the bottom of the furniture, and the user can easily reach under the bed or sofa to clean without bending over, thereby improving the user's experience. In some embodiments, the locking fitting 502 includes a locking cavity 502a, and the locking member 501 can move closer to or away from the locking cavity 502a in the axial direction where the first bending rod 100 and the second bending rod 200 are on the same axis, and when the locking member 501 moves along the axial direction until it is locked in the locking cavity 502a, the first bending rod 100 and the second bending rod 200 are locked on the same axis. With the above scheme, after the locking member 501 is locked in the locking cavity 502a, the locking cavity 502a will limit the movement of the locking member 501 in the front-to-back direction, thereby limiting the rotation of the first bending rod 100 relative to the second bending rod 200 in the front-to-back direction, so as to lock the first bending rod 100 and the second bending rod 200 on the same axis; after the locking member 501 moves along the axial direction to disengage from the locking cavity 502a, the first bending rod 100 can rotate relative to the second bending rod 200. In some embodiments, the locking mechanism 500 further comprises a pusher 503 capable of pushing the locking member 501 to move away from the locking cavity 502a along the axial direction on which the first bending rod 100 and the second bending rod 200 are on the same axis, and a first reset member 504 capable of giving the locking member 501 a direction to move toward the locking cavity 502a along the axial direction. In some embodiments, the first reset member 504 comprises a compression spring. In some embodiments, a second reset member 505 is connected between the first bending rod 100100 and the pusher 503, and the second reset member 505 gives the pusher 503 a tendency to always move in a direction away from the first bending rod 100100.By adopting the above scheme, when it is necessary to clean the bottom of the furniture, after the user presses the pushing member 503 with his hand to give a thrust, the pushing member 503 can give a thrust to the locking member 501, so that the locking member 501 moves in the axial direction where the first bending rod 100 and the second bending rod 200 are on the same axis in a direction away from the locking cavity 502a, so as to release the lock between the first bending rod 100 and the second bending rod 200. In this process, the first reset member 504 is compressed and the second reset member 505 is compressed. After the contact lock is reached, the user can release the hand. After releasing the pushing member 503, the rebound force of the first reset member 504 will give a thrust to the locking member 501, so that the locking member 501 is reset. In this process, the locking member 501 gives a thrust to the pushing member 503, and the rebound force of the second reset member 505 gives a thrust to the pushing member 503 to move outward, so that the locking member 501 and the pushing member 505 are released. 03 is reset more smoothly; when it is necessary to clean the outside, the user rotates the first bending rod 100 to make it on the same axis with the second bending rod 200. In this process, after the hand presses the pushing member 503 to give a thrust, the pushing member 503 can give a thrust to the locking member 501, so that the locking member 501 retracts relatively. When the first bending rod 100 is rotated to the point where it is on the same axis with the second bending rod 200, the user releases his hand, and the first reset member 504 rebounds. The force will give a thrust to the locking member 501, and the locking member 501 gives a thrust to the pushing member 503. The locking member 501 is pushed to move toward the locking cavity 502a until it is locked in the locking cavity 502a. The rebound force of the second reset member 505 gives a thrust to the pushing member 503 to move outward, so that the reset of the locking member 501 and the pushing member 503 is smoother; so as to realize the locking between the first bending rod 100 and the second bending rod 200.In some embodiments, the pushing member 503 is disposed on a side of the locking member 501 away from the first bending rod 100; and a first inclined end surface 503a is disposed on a side of the pushing member 503 close to the locking member 501, and the first inclined end surface 503a is inclined from the first bending rod 100 toward the second bending rod 200 in the axial direction where the first bending rod 100 and the second bending rod 200 are on the same axis by the pushing member 503 toward the direction close to the locking member 501; The locking member 501 includes a second inclined end surface 501a that can abut against the first inclined end surface 503a; when the pushing member 503 is pressed to move toward the direction close to the locking member 501, the first inclined end surface 503a gives a thrust to the second inclined end surface 501a, so that the locking member 501 moves along the axis direction of the first bending rod 100 and the second bending rod 200 on the same axis in the direction away from the locking cavity 502a, and the locking member 501 is separated from the locking cavity 502a. In some embodiments, the first bending rod 100 is provided with a receiving member 105 for accommodating the locking member 501, the first reset member 504 and the pushing member 503, and the pushing member 503 is partially placed outside to facilitate the user's pressing operation; the locking member 501 is also provided with an avoidance groove 501b for avoiding the pushing member 503, so as to prevent the locking member 501 from restricting the movement of the pushing member 503 during the pressing of the pushing member 503. By adopting the above scheme, in the process of pressing the pushing member 503 to move it in the direction close to the locking member 501, due to the cooperation between the first inclined end surface 503a and the second inclined end surface 501a, the locking member 501 can be forced to move in the direction away from the locking cavity 502a, so as to release the lock between the first bending rod 100 and the second bending rod 200; after releasing the pushing member 503, the first reset member 504 will give the locking member 501 a force to move in the direction close to the locking cavity 502a, then due to the cooperation between the first inclined end surface 503a and the second inclined end surface 501a, the pushing member 503 is pushed to translate in the direction away from the locking member 501, and the locking member 501 will be pushed until it cooperates with the locking cavity 502a to lock, and the first reset member 504 will give the locking member 501 a tendency to always move in the direction close to the locking cavity 502a, so as to ensure that the locking member 501 is locked in the locking cavity 502a.

In some embodiments, the first limiting portion 102 is arranged on the first bending rod 100 and is placed between the locking piece 501 and the first rotating axis 103, and the distance between the first limiting portion 102 and the first rotating axis 103 can avoid the rotation of the support rod 400; and the first limiting portion 102 is formed by the outer wall protrusion of the first bending rod 100, and while positioning the first bending rod 100 and the support rod 400, it can also limit the first bending rod 100 to only rotate forward relative to each other; the second limiting portion 202 is arranged on the second bending rod 200 and is placed between the locking fitting 502 and the second rotating axis 203, and the distance between the second limiting portion 202 and the second rotating axis 203 can avoid the rotation of the support rod 400; and the second limiting portion 202 is formed by the outer wall protrusion of the second bending rod 200, and while positioning the second bending rod 200 and the support rod 400, it can also limit the support rod 400 to only rotate forward relative to the second bending rod 200.
