Description

Technical Field

[0001] This utility model relates to the field of cleaning tool technology, and more specifically, to a replaceable floor cleaning brush head. Background Technology

[0002] In everyday cleaning scenarios, floor cleaning tools (such as mops) are commonly used cleaning equipment in homes and commercial spaces. Their core working component is the floor cleaning brush head, and the functional adaptability and flexibility of the brush head directly determine the cleaning efficiency and convenience. Currently, most mops on the market adopt a single brush head design, meaning that a mop is equipped with only one type of brush head, or only has the function of brushing or only has the function of mopping.

[0003] Even if some mops have replaceable brush heads, the original cleaning components must be disassembled first, and then the corresponding functional components must be replaced, making it impossible to brush and mop simultaneously. This single-function design forces users to frequently switch between mops with different functions or repeatedly disassemble and replace the same mop's brush head during the cleaning process. This not only increases the number of cleaning steps and workload but may also cause cleaning interruptions due to frequent tool switching, reducing overall cleaning efficiency. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a replaceable floor cleaning brush head, thus solving the problems of limited functionality and cumbersome switching of existing mop brush heads.

[0005] To achieve the above objectives, this utility model provides a replaceable floor cleaning brush head, including a brush head bracket, a fixing rod, a brush head extension rod, and a fixing mechanism. The brush head bracket is fixedly connected to one end of the fixing rod. The end of the fixing rod away from the brush head bracket is detachably fixed to the mop body. A slot is formed at the end of the brush head bracket away from the fixing rod. A connecting shaft is fixedly connected between the opposing inner walls of the slot. The middle part of the brush head extension rod is rotatably sleeved on the connecting shaft, and the volume of the slot is adapted to the rotation stroke of the brush head extension rod. A first brush head and a second brush head are respectively hinged to both ends of the brush head extension rod. The first brush head and the second brush head are used to perform different floor cleaning operations. The structures of the first brush head and the second brush head are compatible and can be independently disassembled and replaced. The fixing mechanism is disposed between the brush head extension rod and the brush head bracket. The fixing mechanism is used to fix the brush head extension rod and the brush head bracket relative to each other after the brush head extension rod rotates to the target angle.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Preferably, the fixing mechanism includes a locking block, a locking rod, and an elastic reset member. Two locking blocks are provided, symmetrically fixed to the side of the brush head extension rod near the fixing rod, and each locking block has a locking hole. The fixing rod has a hollow structure, and a support bracket is fixed inside the hollow cavity of the fixing rod. The locking rod slides through the support bracket, and the bottom end of the locking rod slides sequentially through the bottom wall of the fixing rod and the top wall of the brush head bracket, extending into the slot. The elastic reset member is sleeved on the portion of the locking rod located within the hollow cavity of the fixing rod, with one end abutting against the support bracket and the other end abutting against a baffle fixed to the locking rod. When the brush head extension rod rotates to the target angle, the locking hole corresponds to the bottom end of the locking rod, and the bottom end of the locking rod can be inserted into the locking hole.

[0008] Preferably, the height of the slot is less than the distance from the axis of the connecting shaft to the end of the brush head extension rod, and when the brush head extension rod rotates to abut against the inner wall of the brush head bracket, the locking block on the raised end of the brush head extension rod is located in the slot, and the axis of the locking hole is collinear with the axis of the locking rod.

[0009] Preferably, the bottom end of the locking rod and the edge of the locking block away from the brush head extension rod are rounded to reduce the frictional resistance between the locking block and the locking rod when the brush head extension rod rotates.

[0010] Preferably, the elastic reset element is a cylindrical helical spring, and the inner diameter of the spring is adapted to the outer diameter of the locking rod.

[0011] Preferably, the system also includes a control assembly, which includes a control sleeve, a connecting rod, and a spiral groove. The control sleeve is slidably fitted onto the outer wall of the fixed rod. A spiral groove is formed on the side wall of the fixed rod corresponding to the position of the control sleeve. The spiral groove extends along the axial direction of the fixed rod and is distributed in a spiral shape. One end of the connecting rod is fixed to the inner wall of the control sleeve, and the other end passes through the spiral groove and is fixedly connected to the portion of the locking rod located in the hollow cavity of the fixed rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The efficiency of brush head switching is significantly improved. No parts need to be disassembled. The dual brush head switching can be completed quickly by simply rotating the brush head extension rod in conjunction with the unlocking of the control component and the automatic locking of the fixing mechanism. This avoids interruption of the cleaning process, greatly reduces the number of cleaning operation steps, and improves the overall cleaning efficiency. Users can choose from different brush heads to suit their cleaning needs, such as hard brushes with soft brushes, dry brushes with wet brushes, etc., and they can be disassembled and replaced independently.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4 As shown, this embodiment provides a replaceable floor cleaning brush head, including a brush head bracket 1, a fixing rod 2, a brush head extension rod 3, and a fixing mechanism 4. The brush head bracket 1 is fixedly connected to one end of the fixing rod 2 to form an integral support structure. The end of the fixing rod 2 away from the brush head bracket 1 is detachably fixed to the mop body, facilitating overall disassembly and installation, and adapting to the usage needs of different mop bodies.

[0017] A slot 8 is provided at the end of the brush head bracket 1 away from the fixed rod 2. The slot 8 provides the necessary space for the rotation of the brush head extension rod 3. A connecting shaft 5 is fixedly connected between the slot 8 and the inner wall of the bracket. The connecting shaft 5 serves as the fulcrum for the rotation of the brush head extension rod 3, enabling the brush head extension rod 3 to rotate stably. The middle part of the brush head extension rod 3 is rotatably sleeved on the connecting shaft 5, and the volume of the slot 8 is adapted to the rotation stroke of the brush head extension rod 3, ensuring that the brush head extension rod 3 will not be unable to reach its position due to space constraints during rotation. A first brush head 6 and a second brush head 7 are respectively hinged to both ends of the brush head extension rod 3. The structures of the first brush head 6 and the second brush head 7 are compatible and can be independently disassembled and replaced. Users can select different functional brush heads according to their cleaning needs (such as brushing the floor or mopping the floor). When a single brush head wears out, only the corresponding brush head needs to be replaced, reducing usage costs.

[0018] The fixing mechanism 4 is located between the brush head extension rod 3 and the brush head bracket 1. Its function is to fix the brush head extension rod 3 and the brush head bracket 1 relative to each other after the brush head extension rod 3 is rotated to the target angle, so as to prevent the brush head extension rod 3 from rotating randomly during the cleaning process and affecting the cleaning effect.

[0019] In summary, the improvement of this embodiment is that the brush head switching efficiency is significantly improved. No parts need to be disassembled. The dual brush head switching can be completed quickly by simply rotating the brush head extension rod 3 in conjunction with the unlocking of the control component 9 and the automatic locking of the fixing mechanism 4. This avoids interruption of the cleaning process, greatly reduces the number of cleaning operation steps, and improves the overall cleaning efficiency.

[0020] Based on the above, other structures also need to be disclosed in detail, such as: Specifically, the fixing mechanism 4 includes a locking block 401, a locking rod 402, and an elastic reset member 403. Two locking blocks 401 are provided, symmetrically fixed to the side of the brush head extension rod 3 near the fixing rod 2, and each locking block 401 has a locking hole 405 to provide a mating point for locking. The fixing rod 2 has a hollow structure, and a support bracket 201 is fixed inside its hollow cavity. The support bracket 201 provides stable sliding support for the locking rod 402. The locking rod 402 slides through the support bracket 201, and its bottom end slides sequentially through the bottom wall of the fixing rod 2, the top wall of the brush head bracket 1, and extends into the slot 8, ensuring that the locking rod 402 can precisely engage with the locking hole 405 on the locking block 401. The elastic reset member 403 is sleeved on the part of the locking rod 402 located in the cavity of the fixed rod 2. One end of the elastic reset member 403 abuts against the support bracket 201, and the other end abuts against the baffle 404 fixed on the locking rod 402. In the natural state, the elastic reset member 403 pushes the locking rod 402 downward through its own elastic force. When the brush head extension rod 3 rotates to the target angle, the locking hole 405 corresponds to the bottom end of the locking rod 402, and the bottom end of the locking rod 402 can be inserted into the locking hole 405 to achieve automatic locking.

[0021] Furthermore, the height of the slot 8 is less than the distance from the axis of the connecting shaft 5 to the end of the brush head extension rod 3. This size design ensures that the end of the brush head extension rod 3 will not enter the slot 8 when it rotates, thus ensuring a compact and reasonable structure. When the brush head extension rod 3 rotates to abut against the inner wall of the brush head bracket 1, the locking block 401 on the raised end of the brush head extension rod 3 is located in the slot 8, and the axis of the locking hole 405 is collinear with the axis of the locking rod 402, ensuring that the locking rod 402 can be accurately inserted into the locking hole 405 to complete the locking.

[0022] Meanwhile, the bottom end of the locking rod 402 and the edge of the locking block 401 away from the brush head extension rod 3 are rounded. This design can reduce the frictional resistance between the locking block 401 and the locking rod 402 when the brush head extension rod 3 rotates, making the rotation operation smoother and reducing component wear.

[0023] The elastic reset component 403 is a cylindrical helical spring. The inner diameter of the spring is adapted to the outer diameter of the locking rod 402 to ensure that the spring can be stably sleeved on the locking rod 402, preventing the spring from shifting during the extension and retraction process, and ensuring the stable realization of the elastic reset function.

[0024] In addition, the floor cleaning brush head also includes a control component 9, which includes a control sleeve 901, a connecting rod 902, and a spiral groove 903. The control sleeve 901 is slidably fitted onto the outer wall of the fixed rod 2 for easy user operation. A spiral groove 903 is provided on the side wall of the fixed rod 2 corresponding to the position of the control sleeve 901. The spiral groove 903 extends along the axial direction of the fixed rod 2 and is spirally distributed to guide the movement of the connecting rod 902. One end of the connecting rod 902 is fixed to the inner wall of the control sleeve 901, and the other end passes through the spiral groove 903 and is fixedly connected to the part of the locking rod 402 located in the hollow cavity of the fixed rod 2. By sliding the control sleeve 901, the user can drive the locking rod 402 to rise and fall, realizing convenient locking and unlocking operations.

[0025] In summary, the workflow of this solution is as follows: The user holds the control sleeve 901 and slides it upwards to the top of the fixed rod 2. The connecting rod 902 drives the locking rod 402 to move upwards, disengaging it from the empty groove 8 area. The user then presses down on the end of the first brush head 6 with the other hand, causing the brush head extension rod 3 to rotate downwards around the connecting shaft 5 until the side wall of the extension rod abuts against the empty groove 8. At this point, the first brush head 6 is just touching the ground, and the second brush head 7 is lifted.

[0026] When the extension rod reaches its limit position, the locking block 401 corresponding to the first brush head 6 rotates exactly to the bottom of the locking rod 402. During this process, the locking rod 402 is pushed open. Then, because the locking hole 405 is aligned with the axis of the locking rod 402, the elastic reset member 403 pushes the locking rod 402 downward into the locking hole 405 to complete the locking.

[0027] The user holds the mop body and uses the first brush head 6 to clean stubborn stains and crevices on the floor. The second brush head 7 is lifted and left idle, without contacting the floor or the empty groove 8, so as not to affect the cleaning operation.

[0028] When switching to the second brush head 7, slide the control sleeve 901 upwards. The connecting rod 902 drives the locking rod 402 upwards to disengage from the locking hole 405 corresponding to the first brush head 6, thus unlocking it. Lift the end of the first brush head 6 upwards, causing the brush head extension rod 3 to rotate upwards around the connecting shaft 5 until the side wall of the extension rod abuts against the upper wall of the slot 8. At this time, the second brush head 7 is in close contact with the ground. The first brush head 6 is lifted, and the second brush head 7 is used to wipe and remove dust from the cleaned ground, realizing a continuous cleaning process of "brushing first and then wiping".
