Description

Technical fields:

[0001] This invention relates to a control structure for a PVC trolley head. Background technology:

[0002] Currently, cleaning tools on the market include sponge mops and mop buckets. A sponge mop includes a mop handle and a sponge head located at the lower end of the handle. The sponge head includes a panel and a sponge head located below the panel. A guide rail is provided at the lower part of the panel, running along its length. Multiple guide blocks are spaced apart above the sponge head. The sponge head's ends are guided and moved closer together by the cooperation of the guide blocks and the guide rail. A mop bucket includes a bucket body with a support section inside. When squeezed, the sponge head rotates along its length to be parallel to the mop handle. The lower end of the sponge head is supported by the support section. Holding the mop handle and pressing down causes the upper end of the sponge head to be guided and moved closer to the supported lower end, thus deforming and squeezing it. However, because at least one end of the PVA mop head is not fixed to the panel when the mop is not compressed, the friction between the mop head and the floor causes the two ends to move closer together. Furthermore, the unfixed end of the mop head is prone to damage due to long-term irregular twisting. Therefore, this structure of the PVA mop head affects both cleaning effectiveness and product lifespan. Existing Chinese patent document 201921679273.8 discloses a mop head, mop, and mopping assembly that also suffers from the same defects. Summary of the Invention:

[0003] One object of the present invention is to provide a plywood mop that solves the above-mentioned problems.

[0004] To achieve the above-mentioned objectives, the present invention is implemented through the following technical solution: a control structure for a PVA mop head, wherein the PVA mop includes a mop handle and a PVA mop head disposed at the lower end of the mop handle, the PVA mop head includes a panel and a PVA head disposed below the panel, a guide rail is provided at the lower part of the panel, the guide rail is arranged along the length direction of the panel, and a plurality of guide blocks are provided at intervals above the PVA mop head, the PVA mop head is connected to the panel by being mounted on the guide rail through the guide blocks, and in the squeezing state, the two ends of the PVA mop head can be guided to move closer together through the cooperation of the guide blocks and the guide rail; the characteristic is that: the PVA mop head is provided with a control structure, in the non-squeezing state, the control structure is used to restrict the PVA mop head so that its two ends cannot move closer together, in the squeezing state, the PVA mop head rotates in the length direction to be parallel to the mop handle, and while the PVA mop performs squeezing in conjunction with the wringing structure, its control structure is triggered to release the restricted end of the PVA mop head, so that the movable end can move closer to the other end to perform deformation squeezing.

[0005] In this invention, the control structure includes a first limiting structure, which comprises a slot and a locking head. The slot and locking head are respectively located on the panel and the sponge head. The locking head engaging with the slot restricts the movable end of the sponge head from moving towards the other end. An elastic structure is installed in the panel. In the non-squeezing state, the elastic structure forces the sponge head to engage the locking head with the slot, thus restricting the movable end. In the squeezing state, the sponge mop, in conjunction with the wringing structure, performs squeezing, and simultaneously, the movable end of the sponge head is activated, causing the locking head to disengage from the slot, allowing the movable end to move towards the other end. The aforementioned first limiting structure achieves the purpose of restricting the movable end of the sponge head with the panel in the non-squeezing state, and allowing the movable end of the sponge head to move towards the other end for squeezing in the squeezing state.

[0006] In this invention, the elastic structure includes an actuator rotatably connected to the panel. The actuator, via a spring or an extended elastic arm, causes its non-connected end, which is elastic, to abut against the adhesive cotton head, thereby facilitating the insertion of the adhesive cotton head into the slot when not compressed. This structure achieves the purpose of restricting the movable end of the adhesive cotton head by the panel when the first limiting structure is in a non-compressed state.

[0007] In this invention, the squeezing structure includes an actuating part. During the squeezing process, the movable end of the cotton head moves after contacting the actuating part, causing the clamping head to exit the clamping slot, thereby disengaging the movable end of the cotton head from the panel constraint. This structure achieves the purpose of disengaging the movable end of the cotton head from the panel constraint when the first limiting structure is in the squeezing state.

[0008] In this invention, the slot is located at the lower part of the guide rail, the card head is located on the guide block, and the slot is angled to facilitate the entry and exit of the card head. This structure further optimizes the product.

[0009] In this invention, the control structure includes a first limiting structure B, which comprises a slot B and a locking head B. The slot B is located on the PVC mop head, and the locking head B is movably mounted on the panel. The engagement of the locking head B with the slot B restricts the movable end of the PVC mop head from moving towards the other end. An elastic structure B is installed in the panel, providing elasticity to the locking head B. In the non-squeezing state, the elastic structure B forces the locking head B into the slot B, thus restricting the movable end. In the squeezing state, while the PVC mop mop uses a wringing mechanism to squeeze, the locking head B in the panel is activated, causing it to disengage from the slot B, allowing the movable end to move towards the other end. The first limiting structure B also achieves the same purpose: in the non-squeezing state, the movable end of the PVC mop head is restricted by the panel, and in the squeezing state, the movable end of the PVC mop head is released from the panel's restriction and can move towards the other end to perform squeezing.

[0010] In this invention, the locking head B is rotatably mounted on the panel. The locking head B includes a locking head at one end, adjacent to the adhesive cotton head, which engages with the slot B for positioning. The other end of the locking head B is an operating end, protruding from the panel and exposed. Moving the operating end allows the locking head to enter or exit the slot B. The elastic structure B includes an elastic arm B extending from the locking head B, or a spring installed between the panel and the locking head B. The elastic force of the elastic arm B or the spring causes the locking head of the locking head B to enter the slot B when not compressed. This structure achieves the purpose of restricting the movable end of the adhesive cotton head by the panel when the first positioning structure B is not compressed.

[0011] In this invention, the squeezing structure includes an actuating part B. During the squeezing process, the operating end of the clamping head B moves after contacting the actuating part B, causing the locking head to exit the clamping slot B, thereby disengaging the movable end of the cotton head from the panel constraint. This structure achieves the purpose of disengaging the movable end of the cotton head from the panel constraint when the first limiting structure B is in the squeezing state.

[0012] In this invention, the control structure includes a second limiting structure to prevent the other end of the adhesive cotton head from moving relative to the panel. The above structure, combined with either the first limiting structure or the first limiting structure B, achieves the purpose of the control structure.

[0013] In this invention, the second limiting structure includes a movable lock head B mounted on the panel, and a sliding groove provided at the fixed end of the adhesive head. The movement of the lock head B in the panel into the sliding groove restricts the fixed end of the adhesive head to prevent it from moving, or the movement of the lock head B in the panel exits the sliding groove, allowing the fixed end of the adhesive head to be released from the panel restriction and thus detached from the adhesive head. The above structure can achieve the purpose of the second limiting structure.

[0014] The advantages of this invention are as follows: because the PVC mop head of this invention is provided with a control structure, when not in a squeezed state, the control structure is used to restrict the PVC mop head so that its two ends cannot move close together. When cleaning the floor, the PVC mop head will not stretch, twist, or wobble due to friction with the floor, thereby making the PVC mop head more efficient and the product has a longer service life.

[0030] Detailed implementation: The present invention will be further described below with reference to the accompanying drawings and through embodiments.

[0031] Reference Figures 1 to 6As shown: This invention discloses a control structure for a plywood mop head. The plywood mop includes a mop handle 1 and a plywood mop head 2 located at the lower end of the mop handle. The plywood mop head includes a panel 3 and a plywood head 4 located below the panel. A guide rail 5 is provided at the lower part of the panel, and the guide rail is arranged along the length direction of the panel. A plurality of guide blocks 6 are provided at intervals above the plywood head. The plywood head is connected to the panel by being mounted on the guide rail through the guide blocks. In the squeezing state, the two ends of the plywood mop head can be guided to move closer together through the cooperation of the guide blocks and the guide rail. The invention is characterized in that: the plywood mop head is provided with a control structure. In the non-squeezing state, the control structure is used to restrict the plywood head, preventing its two ends from moving closer together. In the squeezing state, the plywood mop head rotates along its length direction to be parallel to the mop handle. While the plywood mop is squeezing in conjunction with the wringing structure, its control structure is triggered, causing the movable end of the plywood head to be released from the restriction, thereby allowing the movable end to move closer to the other end for deformation squeezing. The guide rail and guide block have various structures, such as the guide rail and guide block structure in patent number 202020011655.X; and the various guide components and mounting block structures given in patent number 201921679273.8. The guide rail can be detachably connected to the panel or the guide rail and the panel can be integrated as one piece. The detachable guide rail is connected to the panel by screws or by various existing snap-fit ​​methods.

[0032] In this embodiment, the control structure includes a first limiting structure, which includes a slot 7 and a locking head 8. The slot and locking head are respectively located on the panel 3 and the adhesive head 4. The locking head engaging with the slot restricts the movable end of the adhesive head from moving towards the other end. An elastic structure is installed in the panel. In a non-squeezing state, the elastic structure forces the adhesive head to engage with the locking head in the slot, thus restricting the movable end of the adhesive head. In a squeezing state, the adhesive mop, in conjunction with the wringing structure, squeezes the adhesive head while simultaneously triggering the locking head to disengage from the slot, allowing the movable end to move towards the other end. The aforementioned locking head and slot corresponding to the cross-arrangement of the adhesive head and panel should all be considered within the same scope of application.

[0033] In an embodiment, the elastic structure includes an actuator 9, which is rotatably connected to the panel 3. The actuator has an elastic non-connecting end 21 that comes into contact with the cotton head by means of an installed spring or an extended elastic arm 10, so that the clamping head 8 of the cotton head enters the slot 7 when it is not squeezed.

[0034] In this embodiment, the squeezing structure includes an actuating part 11. During the squeezing process, the movable end of the cotton head moves after contacting the actuating part, causing the clamping head 8 to exit the clamping slot 7, thereby freeing the movable end of the cotton head 4 from the restriction of the panel 3. The movable end of the cotton head moves at an angle after contacting the actuating part, causing the clamping head to move at an angle and exit the clamping slot. The aforementioned angle movement can be achieved by setting the contact surfaces of the cotton head and the actuating part at different angles. There are various squeezing structures, such as Example 1, patent number: 202020011655. X, the dewatering structure includes a support portion in a water storage tank. When the sponge mop head is rotated along its length to a vertical position with the mop handle, the lower end of the sponge head can be supported by the support portion. During dewatering, pressing down on the mop handle causes the upper end of the sponge head to move downwards towards the supported lower end, thereby squeezing and dewatering the sponge head. The trigger portion is located in the support portion. For example, in patent number 201921679273.8, the dewatering structure is a dewatering tank 23, which has a protruding component 22 inside. The protruding component serves as a support portion to support the sponge head. The trigger portion 11 is located in the protruding component. For example, in patent number 20192167927, the dewatering structure is a dewatering tank 23, which has a protruding component 22 inside. The protruding component serves as a support portion to support the sponge head. 3.8, the squeezing structure is a squeezing bucket with a squeezing nozzle, the squeezing nozzle allowing the mop panel to pass through along its length, one edge of the squeezing nozzle forming a stop portion to block the cotton head, and the trigger portion is located on the stop portion; for example, Example 4, Patent No.: 201921679273.8, the squeezing structure is a squeezing frame slidably disposed on the mop handle, so that when the mop head and the mop handle are in a parallel position, the sliding squeezing frame squeezes the wiping part to produce deformation, the squeezing frame is provided with an opening for the mop panel to pass through longitudinally and a stop portion that can block the wiping part; the trigger portion is located on the stop portion.

[0035] In this embodiment, the slot is located at the lower part of the guide rail 5, and the clamping head is located on the guide block 6. The slot is angled to facilitate the clamping head entering or exiting the slot. Extrusion plates 20 are respectively provided on the sides at both ends of the length direction of the adhesive head. The extrusion plates are made of rigid material and facilitate support of the adhesive head and compression when the two ends of the adhesive head are close together. The clamping head can also be located on the extrusion plate.

[0036] In an embodiment, the control structure includes a second limiting structure to prevent the other end of the adhesive head from moving relative to the panel. The second limiting structure includes a movable lock head B18 mounted on the panel, and a groove 19 on the fixed end of the adhesive head. The lock head B moves into the groove within the panel, restricting the fixed end of the adhesive head from moving, or it moves out of the groove, freeing the fixed end of the adhesive head from panel restriction and allowing it to be disassembled. The direction of movement of the lock head B within the panel is the same as the shorter direction of the panel. The groove can be located on the squeezing plate 20 or guide block 6 of the adhesive head. The panel has a through-hole, and the lock head B includes an upper fastener and a lower fastener that can be interlocked. The lower end of the upper fastener passes through the through-hole and interlocks with the lower fastener on the other side of the panel. After interlocking, the outer ends of the upper and lower fasteners are larger than the through-hole, thus the lock head B is mounted on the panel and can move with the through-hole without detaching. Many locking structures similar to the above-described second limiting structure exist, such as… Figures 8-9 In the given structure 2, the second limiting structure includes a locking head C24 and a locking groove C27. The locking head C and the locking groove C are respectively located on the panel 3 and the adhesive head 4. When the locking head C is movably installed on the panel, the locking groove C is located on the adhesive head. A spring is provided between the locking head C and the panel, or the locking head extends with an elastic arm C25. The spring or the elastic arm C25 provides elastic force to the locking head C26 at the front end of the locking head C to enter the locking groove C27, so that the fixed end of the adhesive head is restricted by the panel and cannot move. For example, in structure 3, patent number 202020011655.X, the switching device includes a rocker arm connected to the cover plate via a lever mechanism below the cover plate. One end of the rocker arm is elastically extended relative to the cover plate, and the other end can pass through the cover plate for pressing operation. A limiting position is provided on the adhesive head, and the extended end of the rocker arm can engage with the limiting position to prevent the guide block from detaching from the guide rail. When the switch is opened: operating the pressing end of the rocker arm causes the extended end to tilt upwards, disengaging from the limiting position, allowing the guide block to detach from the guide rail, thus enabling the adhesive head to be detached from the cover plate. This second limiting structure, combined with the guide rail closed at the other end of the panel, can limit the movement of the adhesive head within the guide rail, preventing it from detaching.

[0037] The working process of this embodiment is as follows: In the non-squeezing state, the actuator causes the clamp of the cotton head to enter the slot, so that the movable end of the cotton head is restricted by the panel and cannot move to the other end. The fixed end of the cotton head is restricted to the panel by the second limiting structure, so that the two ends of the cotton head cannot move close to each other. In the squeezing state, the cotton mop head rotates in the length direction to be parallel to the mop handle. The cotton mop performs squeezing in conjunction with the wringing structure. At the same time, the movable end of the cotton head moves after contacting the trigger part to cause the clamp to exit the slot. So that the movable end of the cotton head is freed from the panel restriction and can move close to the other end to perform deformation squeezing.

[0038] Because the PVC mop head of the present invention is provided with a control structure, when not in a squeezed state, the control structure is used to restrict the PVC mop head so that its two ends cannot move close together. When cleaning the floor, the PVC mop head will not stretch, twist, or wobble due to friction with the floor, thereby making the PVC mop head more efficient and the product's service life longer.

[0039] Reference Figures 7 to 13 The following is an embodiment 2 of the present invention. The control structure includes a first limiting structure B, which includes a slot B12 and a locking head B13. The slot B is located on the PVC mop head 4, and the locking head B is movably mounted on the panel 3. When the locking head B enters the slot B, the movable end of the PVC mop head is restricted by the panel and cannot move towards the other end. An elastic structure B is installed in the panel, which imparts elasticity to the locking head B. In the non-squeezing state, the elastic structure B causes the locking head B13 to enter the slot B12, thereby restricting the movable end by the panel. In the squeezing state, when the PVC mop mop performs squeezing in conjunction with the wringing structure, the locking head B in the panel is activated, causing the locking head to exit the slot B, thereby allowing the movable end to move towards the other end. The locking head B13 is rotatably mounted on the panel 3. The locking head B includes a locking head 14 at one end, adjacent to the adhesive head 4. The locking head can engage with the slot B12 for positioning. The other end of the locking head B is an operating end 15, which protrudes from the panel and is exposed. Moving the operating end allows the locking head of the locking head to enter or exit the slot B. The elastic structure B includes an elastic arm B16 extending from the locking head B, or a spring installed between the panel and the locking head B. The elastic force of the elastic arm B or the spring causes the locking head of the locking head B13 to enter the slot B12 when not compressed. Squeezing plates 20 are respectively provided on the sides at both ends of the adhesive head along its length. The squeezing plates are made of rigid material and facilitate support for the adhesive head and compression when the two ends of the adhesive head are close together. The slot B can be located on the squeezing plate or a guide block. The aforementioned structures of the locking head B and slot B corresponding to the cross-arrangement of the adhesive head and the panel should all be considered within the same scope of application.

[0040] In an embodiment, the squeezing structure includes an actuating part B28. During the squeezing process, the operating end of the card head B moves after contacting the actuating part B to cause the locking head to exit the card slot B, thereby causing the movable end of the cotton head 4 to disengage from the panel 3. There are various types of dewatering structures. For example, in Patent No. 202020011655.X, the dewatering structure includes a water storage tank 23 with a support part 30. When the sponge mop head is rotated along its length to the same vertical position as the mop handle, the lower end of the sponge head can be supported on the support part. During dewatering, holding the mop handle and pressing down causes the upper end of the sponge head to move downwards towards the supported lower end, thereby forming a dewatering process. The trigger part B28 is located on the support part. Another example is Patent No. 201921679273.8, where the dewatering structure is a dewatering bucket with a protruding part inside. The protruding part serves as a support for the sponge head. The trigger part B is located on the protruding part. Yet another example is Patent No. 201921679273. .8, the squeezing structure is a squeezing bucket with a squeezing nozzle, which allows the mop panel to pass through along its length. One edge of the squeezing nozzle forms a stop portion to block the cotton head. The trigger portion B is located on the stop portion. For example, Example 4, Patent No.: 201921679273.8, the squeezing structure is a squeezing frame slidably disposed on the mop handle, so that when the mop head and the mop handle are in a parallel position, the sliding squeezing frame squeezes the wiping part to produce deformation. The squeezing frame is provided with a through-hole for the mop panel to pass through longitudinally and a stop portion that can block the wiping part; the trigger portion B is located on the stop portion. The second limiting structure of this embodiment is the same as that of Embodiment 1.

[0041] The working process of this embodiment is as follows: In the non-compression state, the elastic structure B imparts elasticity to the locking head B, causing the locking head of the locking head B in the panel to enter the slot B. The engagement of the locking head into the slot B restricts the movable end of the cotton head from moving closer to the other end. The fixed end of the cotton head is restricted to the panel by the second limiting structure, so that both ends of the cotton head cannot move closer. In the compression state, the cotton mop head rotates in the length direction to be parallel to the mop handle. While the cotton mop performs compression in conjunction with the wringing structure, the moving end of its locking head B, after contacting the trigger part B, causes the locking head to exit the slot B. Thus, the movable end of the cotton head is freed from the panel restriction and can move closer to the other end to perform deformation compression.

[0042] The above embodiments are merely examples of the present invention. Any substitutions or combinations between embodiments made in accordance with the spirit of the present invention should be understood as not departing from the protection scope of the present invention.
