Description

Technical Field

[0001] This utility model belongs to the field of cleaning product structure technology, specifically referring to a mop with a quick-release cleaning head. Background Technology

[0002] Existing rotary mops include a mop head and a yarn fixing disc for securing the yarn. The mop head has a yarn disc connecting part with an annular inner groove. The outer circumference of the yarn fixing disc has several fixing ribs that mate with the annular inner groove. The yarn fixing disc is fastened to the yarn disc connecting part of the mop head by an interference fit between the fixing ribs and the annular inner groove. This design is simple to manufacture and easy to assemble and disassemble. However, the following problems exist in actual production and use: Due to the highly specialized division of labor in this industry, the yarn fixing disc and the yarn connection are processed by specialized manufacturers, while mop manufacturers generally purchase and assemble them. This leads to a problem with the fit between the yarn fixing disc and the mop head produced by the rotary mop manufacturer. If the fit is too loose, the connection between the mop head and the yarn fixing disc will be weak, and the yarn fixing disc will detach from the mop head during use. If the fit is too tight, it will be difficult for the rotary mop manufacturer to install, and difficult for the user to disassemble when replacing the yarn fixing disc.

[0003] For example, Chinese patent CN201920064245.9 describes a rotating mop yarn disc tensioning device, including a mop disc and a yarn fixing disc. The mop disc has a yarn disc connecting part on its outer circumference, and an annular inner groove on the connecting part. The yarn fixing disc has several slots on its outer circumference, and an arc-shaped elastic piece integrally formed with the yarn fixing disc and protruding from the outer circumference is placed inside each slot. In its natural state, the outer diameter of the arc-shaped elastic piece is larger than the inner diameter of the annular inner groove. The yarn fixing disc is fastened and fixed to the yarn disc connecting part of the mop disc, and the head of the arc-shaped elastic piece can elastically deform and lock into the annular inner groove. This product improves the adaptability of the yarn fixing disc through the elastic piece. However, this product still has shortcomings: the yarn fixing disc is not easy to disassemble; users need to use their hands or external force to pry the yarn fixing disc off the mop disc, and repeated forced disassembly can cause irreversible damage to the elastic piece. Summary of the Invention

[0004] The purpose of this invention is to provide a mop with a convenient and quick-detachable cleaning head.

[0005] The purpose of this utility model is achieved as follows:

[0006] A mop with a quick-release cleaning head includes a mop head and a handle, the handle being connected to the mop head, and a wiping material retaining plate that is detachably connected to the mop head; a connecting sleeve is hinged to the mop head, and a sliding sleeve is fixed to the end of the handle; a blocking part that cooperates with the sliding sleeve is provided inside the connecting sleeve, the sliding sleeve moves within the connecting sleeve, and the blocking part restricts the sliding sleeve from disengaging from the connecting sleeve.

[0007] The mop head has at least two slidable claws on its periphery, and a rotating component is rotatably provided on the inner side of the mop head. The rotating component is connected to the claws and can drive the claws to move into the mop head. A threaded transmission rod is connected above the rotating component, and a threaded through-hole for the transmission rod is provided on the inner side of the sliding sleeve. When the handle and the connecting sleeve move relative to each other, the sliding sleeve can drive the transmission rod and the rotating component to rotate synchronously.

[0008] Furthermore, a first hinge block is provided between the mop head and the connecting sleeve. The lower end of the first hinge block is rotatably connected to the mop head, and the upper end of the first hinge block is rotatably connected to the connecting sleeve. The rotation direction of the lower end of the first hinge block is perpendicular to the rotation direction of the upper end of the first hinge block. A second hinge block is provided between the rotating component and the transmission rod. The lower end of the second hinge block is rotatably connected to the rotating component, and the upper end of the second hinge block is rotatably connected to the transmission rod. The rotation direction of the lower end of the second hinge block is perpendicular to the rotation direction of the upper end of the second hinge block. The pawl retracts around the mop head. The first hinge block and the second hinge block rotate in the same direction. The two cooperate with each other to allow the handle to rotate freely relative to the mop head.

[0009] Furthermore, the rotating component is provided with an arc-shaped groove, an inclined groove, or an inclined surface. When the rotating component is driven, the arc-shaped groove, inclined groove, or inclined surface can drive the claw to move into the mop head.

[0010] Furthermore, the claw is provided with a raised edge or protrusion, which is adapted to the arc-shaped groove, inclined groove, or inclined surface of the rotating component; the forward and reverse movement of the rotating component can respectively drive the claw to extend out of the mop head and retract into the mop head.

[0011] Furthermore, a recessed chamber is provided below the mop head, and a wiping material fixing disc can be hidden inside the chamber, with claws hooking onto the peripheral surface of the wiping material fixing disc.

[0012] Furthermore, at least three claws are evenly distributed around the periphery of the mop head, and the claws are driven by the same rotating component.

[0013] Furthermore, it includes a cap, which is fixed to the mop head, and a cavity is formed between the cap and the mop head to house the claw and the rotating part; a guide groove is provided in the cavity, and the claw moves along the guide groove; or, the claw is provided with a guide groove, and the cavity has a protrusion that matches the guide groove.

[0014] Furthermore, the wiping material fixing disc is provided with several raised edges around its periphery.

[0015] Furthermore, the wiping material fixing plate is provided with at least one ring of wiping material mounting holes around its periphery.

[0016] Furthermore, the center of the wiping material fixing plate is hollowed out, and the center of the rotating component is provided with a hole. The cross-section of the hole is polygonal, and the hole is exposed in the hollowed-out position of the center of the wiping material fixing plate.

[0017] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0018] 1. This utility model uses several claws to grip and hold the cleaning disc. First, place the cleaning disc on the ground, unfold the claws, and the cleaning disc enters the recessed cavity below the mop head. Then, retract the claws. During the retraction process, the user only needs to hold the connecting sleeve with one hand and pull the handle with the other, making operation simple. Multiple claws move synchronously to retract and secure the cleaning disc, resulting in strong structural stability.

[0019] 2. This utility model uses a rotating component as the transmission component. The handle and the transmission rod are connected by a screw. The relative movement between the handle and the connecting sleeve is converted into the rotation of the rotating component. The rotating component simultaneously controls the synchronous movement of multiple jaws. The entire process uses a mechanical structure, resulting in strong transmission stability.

[0020] 3. A first hinge block is provided between the mop head and the connecting sleeve of this utility model, and a second hinge block is provided between the rotating part and the transmission rod. By setting the first hinge block and the second hinge block that cooperate with each other, the mop has a better degree of freedom. The handle can swing freely in multiple directions relative to the mop head, making it more comfortable and convenient for the user.

[0021] 4. To ensure the stability of the gripper, except for the exposed claw part, the rest of the gripper is concealed within the chamber between the cap and the mop head. Furthermore, a limiting guide groove is provided within the chamber to allow the gripper to move in a designated direction. Attached Figure Description

Detailed Implementation

[0038] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Figure 1-15 As shown:

[0039] A mop with a quick-release cleaning head includes a mop head 1 and a handle 3, the handle 3 being connected to the mop head 1. It also includes a wiping material retaining plate 9, which is detachably connected to the mop head 1. A connecting sleeve 2 is hinged to the mop head 1, and a sliding sleeve 31 is fixed to the end of the handle 3. A blocking part 22 that cooperates with the sliding sleeve 31 is provided inside the connecting sleeve 2. The sliding sleeve 31 moves within the connecting sleeve 2, and the blocking part 22 prevents the sliding sleeve 31 from detaching from the connecting sleeve 2. The blocking part 22 of the connecting sleeve can be a stepped portion as shown in the attached figure, or it can be a separate component that restricts the sliding sleeve from detaching. Preferably, a stepped portion is provided on the inner side of the connecting sleeve 2, and the sliding sleeve 31 has a stepped portion 32 that cooperates with the stepped portion of the connecting sleeve. At least two claws 11 are slidably arranged on the periphery of the mop head 1, and a rotating component 5 is rotatably arranged on the inner side of the mop head 1. The rotating component 5 is connected to the claws 11 and can drive the claws 11 to move inward into the mop head. A threaded transmission rod 4 is connected above the rotating component 5, and a threaded through-hole 33 for the transmission rod 4 is provided on the inner side of the sliding sleeve 31. When the handle 3 and the connecting sleeve 2 move relative to each other, the sliding sleeve 31 can drive the transmission rod 4 and the rotating component 5 to rotate synchronously. The mechanical transmission method converts the relative movement of the handle 3 and the connecting sleeve into the rotational motion of the rotating component, and the transmission structure is stable.

[0040] A first hinge block 21 is provided between the mop head 1 and the connecting sleeve 2. The lower end of the first hinge block 21 is rotatably connected to the mop head 1, and the upper end of the first hinge block is rotatably connected to the connecting sleeve 2. The rotation direction of the lower end of the first hinge block is perpendicular to the rotation direction of the upper end of the first hinge block. A second hinge block 41 is provided between the rotating component 5 and the transmission rod 4. The lower end of the second hinge block is rotatably connected to the rotating component 5, and the upper end of the second hinge block is rotatably connected to the transmission rod 4. The rotation direction of the lower end of the second hinge block is perpendicular to the rotation direction of the upper end of the second hinge block. The claw 11 retracts around the mop head 1. The rotation directions of the first hinge block 21 and the second hinge block 41 are the same. The two cooperate with each other to realize the free rotation of the handle relative to the mop head.

[0041] There are various ways to drive the chuck with the rotating component: Method 1: The rotating component 5 has an arc-shaped groove 53, an inclined groove, or an inclined surface, and the chuck 11 has a raised edge or protrusion 113. The raised edge or protrusion 113 is adapted to the arc-shaped groove 53, inclined groove, or inclined surface of the rotating component; the forward and reverse movement of the rotating component can respectively drive the chuck to extend out of the mop head and retract into the mop head. Method 2: An inclined surface is provided on the circumference of the rotating component, and the inclined surface is in contact with the surface of the rotating component. An elastic element pulls the chuck to fit against the inclined surface of the rotating component and provides a force for the chuck to move inward; this method can refer to an intermittent structure similar to an eccentric wheel. In Method 1, the movement of the chuck, both inward and outward, is controlled by the rotating component; in Method 2, the outward movement of the chuck is pushed by the inclined surface of the rotating component, and the inward movement of the chuck is pulled by an elastic element (spring or soft rubber). Both methods are acceptable, and manufacturers can choose one for production.

[0042] The mop head 1 has a recessed chamber below it, and the wiping material fixing plate 9 can be hidden inside the chamber. The claw part 111 of the latch can hook onto the peripheral surface of the wiping material fixing plate 9. The recessed chamber is used to align the wiping material fixing plate.

[0043] The mop head 1 has at least three claws 11 evenly distributed around its periphery, and the claws 11 are driven by the same rotating component 5.

[0044] It includes a cover 10, which is fixed to the mop head 1, and a cavity is formed between the cover 10 and the mop head 1 to house the claw and the rotating part.

[0045] The cavity is provided with a guide groove, along which the chuck moves; or, the chuck 11 is provided with a guide groove 112, and the cavity has a protrusion 12 that matches the guide groove 112. Both methods are acceptable, and the chuck moves in a specified direction through the limiting structure.

[0046] The wiping material fixing tray 9 has several raised edges 92 around its periphery. The wiping material fixing tray 9 also has at least one ring of wiping material mounting holes 91 around its periphery. Common wiping materials such as cotton thread or brush bristles can be fixed within the wiping material mounting holes 91 of the wiping material fixing tray.

[0047] The wiping material fixing plate 9 has a hollow center, and the rotating component 5 has a hole 52 in its center. The hole 52 has a polygonal cross-section and is exposed in the hollow center of the wiping material fixing plate. This hole is used for connecting an external mop bucket, allowing the mop to be positioned.

[0048] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
