Description

Technical Field

[0001] This invention relates to the field of cleaning tools technology, and in particular to a mop head locking and unlocking structure and a mop bucket. Background Technology

[0002] Cleaning and mopping are essential for maintaining hygiene and keeping homes and offices tidy. With urbanization and improved living standards, people are paying increasing attention to this, leading to a continuous increase and improvement in the structure and types of cleaning tools. Mops, as a cleaning tool, come in various styles depending on the requirements of the cleaning environment. Sponge mops are a commonly used type of manual mop. To facilitate user use and minimize soiling clothes while mopping, existing sponge mops typically employ two methods for cleaning and wringing out water: one is a sponge mop with a built-in wringer head. The advantage of this method is that it eliminates the need for a separate mop bucket for cleaning and wringing, making it convenient and space-saving. The disadvantages are that the mop itself has a complex structure, high cost, and the built-in wringer head is prone to damage. The other method involves designing a dedicated mop bucket for cleaning and wringing out water. The advantage of this method is better cleaning and wringing, and the various structures of the sponge mop and mop bucket are less prone to damage. The disadvantages are that it takes up more space, is less convenient to operate, and offers a poor wringing experience. Regarding the mop bucket for wringing out water from a PVA mop, in practical applications, the mop is typically wrung out by pressing down. During this process, the force exerted by the PVA head on the wringer head is downward, and due to the upward support from the ground, the mop bucket remains stationary. However, when the mop is lifted to remove the wringer head, the upward friction between the PVA head and the wringer head can cause the mop bucket to be lifted, especially when the bucket is low on water. Current solutions typically involve users filling the mop bucket with as much water as possible, increasing its weight and the difference between the bucket's own weight and the friction from the PVA head, or manufacturers adding a foot pedal to the mop bucket so the user can secure it to the ground while wringing. Both of these methods increase user limitations and result in a poor user experience. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a mop head locking and unlocking structure and a mop bucket. The technical solution of this invention is as follows:

[0004] A head-scraping locking and unlocking structure includes a head-scraping frame, a locking and unlocking plate, a squeezing roller, and a drive frame. The drive frame is movably connected to the head-scraping frame, and the end of the drive frame near the squeezing roller is a squeezing end, forming a squeezing gap between the squeezing end and the squeezing roller. The locking and unlocking plate is slidably disposed on the head-scraping frame and driven by the drive frame. The head-scraping frame has an inner sliding groove, and the locking and unlocking plate has an outer sliding groove. After the locking and unlocking plate is installed and connected to the head-scraping frame, the inner sliding groove and the outer sliding groove at least partially overlap. The squeezing roller slides within the inner sliding groove and the outer sliding groove. The outer sliding groove includes a locking groove, which restricts the sliding of the squeezing roller in the squeezing direction when the squeezing roller is located within the locking groove.

[0005] As a further explanation of the present invention, the inner and outer chutes are arranged horizontally along the squeezing direction.

[0006] Furthermore, the locking groove is disposed at one end of the outer sliding groove to form an "L" groove.

[0007] Furthermore, the inner and outer sliding grooves are square grooves.

[0008] Furthermore, the dewatering roller includes a square slider located within the inner and outer grooves.

[0009] Furthermore, the square slider is rotatably connected relative to the squeezing roller.

[0010] Furthermore, the inner groove is in the squeezing position near the drive frame and in the original position far from the drive frame. When the locking unlocking piece is in the initial position, the locking groove coincides with the original position of the inner groove, and the squeezing roller is located in the locking groove. When the locking unlocking piece is in the squeezing position, the locking groove coincides with the squeezing position of the inner groove.

[0011] Furthermore, the drive frame is rotatably mounted on the head-strapping frame via an elastic reset member, and the drive frame and the locking / unlocking piece are connected via a connecting shaft. The drive frame drives the locking / unlocking piece to slide left and right via the connecting shaft.

[0012] Furthermore, the locking / unlocking piece is disposed on the outside of the head-strapping frame, the head-strapping frame is provided with a drive slide groove, the front end of the drive frame is provided with a connecting slide groove, the connecting shaft passes through the drive slide groove and slides within the drive slide groove and the connecting slide groove.

[0013] The swivel head locking and unlocking structure of the present invention can be applied to mop buckets and installed on the lid of the mop bucket, making it a mop bucket suitable for cleaning and wringing water from a sponge mop.

[0014] The beneficial effects of this invention are:

[0015] This invention is primarily applied to mop buckets used for wringing out water from PVA mops. During the wringing process, the downward force of the PVA head keeps the wringing roller within the locking groove, restricting its sliding in the wringing direction and achieving a locked state. This maintains optimal wringing action on the PVA head. When the PVA head is pulled back upwards after wringing, the wringing roller automatically disengages from the locking groove, unlocking and resetting to its original position. This maintains the maximum wringing gap and automatically reduces the upward resistance of the PVA head, achieving automatic unlocking of the wringing roller during upward retraction. This prevents the mop bucket from being pulled upwards, allowing users to simply press down to wring and pull back upwards without any additional usage restrictions, greatly improving the user experience of the mop bucket.

[0021] Example:

[0022] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0023] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0024] A head-scraping locking and unlocking structure includes a head-scraping frame 1, a locking and unlocking piece 2, a squeezing roller 3, and a drive frame 4. The drive frame 4 is movably connected to the head-scraping frame 1, and the end of the drive frame 4 near the squeezing roller 3 is a squeezing end, forming a squeezing gap between the squeezing end and the squeezing roller 3. The locking and unlocking piece 2 is slidably disposed on the head-scraping frame 1 and driven by the drive frame 4. The head-scraping frame 1 is provided with an inner sliding groove 101, and the locking and unlocking piece 2 is provided with an outer sliding groove 201. The locking and unlocking piece 2 is slidably installed on the head-scraping frame 1, and one end of the inner sliding groove 101 and the outer sliding groove 201 overlaps each other. The squeezing roller 3 slides within the inner sliding groove 101 and the outer sliding groove 201. The outer sliding groove 201 includes a locking groove 202, which restricts the sliding of the squeezing roller 3 in the squeezing direction when the squeezing roller 3 is located within the locking groove 202. In this embodiment, the initial position of the squeezing roller 3 is located within the locking groove 202.

[0025] Referring to the accompanying drawings, in one embodiment of the present invention, the inner groove 101 is a straight groove, with its near end relative to the drive frame 4 being the squeezing position and its far end relative to the drive frame 4 being the original position. When the squeezing roller 3 is located at the squeezing position, the squeezing gap formed between the squeezing end and the squeezing roller 3 is the smallest, and the squeezing force is the largest; when the squeezing roller 3 is located at the original position, the squeezing gap formed between the squeezing end and the squeezing roller 3 is the largest. In this embodiment, the locking groove 202 is located at one end of the outer groove 201 near the drive frame 4, making the outer groove 201 generally "L" shaped. Referring to the attached figures, when the locking / unlocking piece 2 is located on the right, the locking groove 202 coincides with the original position of the inner sliding groove 101, and the squeezing roller 3 is located within the locking groove 202; when the locking / unlocking piece 2 is located on the left, the locking groove 202 coincides with the squeezing position of the inner sliding groove 101. In this case, pushing down the squeezing roller 3 can keep the squeezing roller 3 in a locked state, restricting its sliding in the squeezing direction; conversely, pushing up the squeezing roller 3 can disengage it from the locked state, and the squeezing roller 3 can slide back to its original position to change the size of the squeezing gap.

[0026] In the above embodiments, the locking groove 202 is preferably a square groove, and preferably, the squeezing roller 3 can be provided with square sliders 301 at both ends, which can increase the locking effect of the locking groove 202 on the squeezing roller 3. The square sliders 301 can be further configured to be rotatable, which can further increase the locking and unlocking effect of the outer groove 201.

[0027] In one embodiment, the drive frame 4 is rotatably mounted on the brush head frame 1. Referring to the accompanying drawings, the rear end of the drive frame 4 is rotatably mounted on the brush head frame 1 via a torsion spring, and a guide wheel 401 is provided on the front squeezing end. In this embodiment, the locking / unlocking piece 2 is disposed on the outer side of the brush head frame 1, and the brush head frame 1 is provided with a drive groove 102. Since the drive frame 4 is rotatably mounted in this embodiment, the drive groove 102 is an arc-shaped groove. The front end of the drive frame 4 is provided with a connecting groove 402, and the locking / unlocking piece 2 is provided with a connecting shaft 203, which slides within the drive groove 102 and the connecting groove 402. Referring to the attached figures, when the drive frame 4 is pressed down and rotates downward, the connecting shaft 203 slides downward in the drive slide groove 102 and the connecting shaft 203 can also slide in the connecting slide groove 402. Therefore, while the drive frame 4 rotates downward, it pulls the locking and unlocking piece 2 to slide to the left, thereby driving the squeezing roller 3 to move to the left and reducing the squeezing gap.

[0028] In another embodiment, a connecting shaft 203 is provided at the front end of the drive frame 4. The connecting shaft 203 passes through the drive slide groove 102 and is connected to the locking / unlocking piece 2. The locking / unlocking piece 2 is provided with a connecting slide groove, and the connecting shaft 203 also slides within the connecting slide groove. When the drive frame 4 is pressed down and rotates downward, the connecting shaft 203 slides downward within the drive slide groove 102, and the connecting shaft 203 can slide up and down within the connecting slide groove on the locking / unlocking piece 2. Therefore, while the drive frame 4 rotates downward, it pulls the locking / unlocking piece 2 to slide to the left, thereby causing the squeezing roller 3 to move to the left and reduce the squeezing gap.

[0029] The squeegee locking and unlocking structure of the present invention is applied to the mop bucket 6 of the plywood mop 5. The squeegee locking and unlocking structure is installed at the wringer head of the mop bucket 6, enabling the plywood mop 5 to wring water, improving the wringing effect and user experience. During the wringing process of the plywood mop 5, the plywood head 501 passes through the wringing gap and presses down, which is the wringing process. During this process, the back of the plywood head 501 presses down on the drive frame 4, causing it to rotate downwards and driving the locking and unlocking piece 2 to move to the left. The wringing roller 3, locked by the locking groove 202, moves to the wringing position along with the locking and unlocking piece 2. At this time, the wringing gap is at its minimum, the wringing force is at its maximum, and during the wringing process, the downward force of the plywood head 501 keeps the wringing roller 3 always within the locking groove 202, restricting the sliding of the wringing roller 3 in the wringing direction, thus achieving a locked state. When the sponge head 501 finishes squeezing out water and is pulled back upwards, the friction between the sponge head 501 and the squeezing roller 3 causes the squeezing roller 3 to move upwards. The square sliders at both ends rotate and unlock, thus automatically disengaging from the locking groove 202. After losing the restriction of the locking groove 202 in the squeezing direction, the squeezing roller 3 automatically returns to its original position to the right under the action of the drive frame 4. At this time, the squeezing gap is at its maximum, so the upward pullback resistance of the sponge head 501 is very small. This achieves automatic unlocking of the squeezing roller 3 when the sponge head 501 is pulled back upwards, preventing the mop bucket 6 from being pulled upwards. Users only need to press down to squeeze out water and pull back upwards normally, without any other unnecessary usage restrictions, greatly improving the user experience of the mop bucket 6. After the cotton head 501 is completely withdrawn from the squeezing gap, the drive frame 4 is fully reset under the action of its own torsion spring, the locking and unlocking piece 2 slides to the right to reset, and under the misalignment of the inner slide groove 101 and the outer slide groove 201, the squeezing roller 3 slides back into the movable groove and locks, entering the next cycle of use.

[0030] The above description only illustrates preferred embodiments of the present invention and should not be construed as limiting the scope of the claims. The present invention is not limited to the above embodiments, and variations in its specific structure are permitted. In short, all variations made within the scope of the independent claims of the present invention are within the scope of protection of the present invention.
