Description

Technical Field

[0001] This utility model relates to the field of mops, specifically to a quick-release structure for a sponge head. Background Technology

[0002] Sponge mops are a common floor cleaning tool, mainly consisting of a base plate and a detachable sponge head attached to the bottom of the base plate. Current sponge mops require both hands to control the sponge head and the base plate separately when removing the sponge head, making sponge head replacement inconvenient and requiring contact with the sponge head, which is considered unhygienic.

[0003] To address the aforementioned issues, Chinese patent CN218852637U discloses a "Quick-Release PVA Mop with PVA Head." This patent utilizes a first fixing part and a first mounting part that are vertically aligned and positioned, and a second fixing part and a second mounting part that are horizontally aligned and positioned. A sliding plate on the fixing plate pushes the second mounting part to create vertical displacement, enabling the detachment of the PVA head. This allows for detachment without hand contact with the PVA head, as the fixing and mounting plates are both vertically and horizontally restricted, preventing the PVA head from falling off during mopping. However, the mounting plate and the second fixing part are fixed to the surface of the PVA head. The vertical movement of the second fixing part relies on its own deformation and the deformation of the PVA head. If the PVA head dries and hardens, the second fixing part cannot move vertically, resulting in the inability to detach the PVA head. Utility Model Content

[0004] One objective of this invention is to provide a quick-release structure for the adhesive cotton head that solves the aforementioned problems.

[0005] To achieve the above-mentioned objectives, this utility model is implemented through the following technical solutions: A quick-release structure for a rubber cotton head includes a fixing plate and a rubber cotton head. The rubber cotton head has a mounting plate. The fixing plate has a first fixing part, and the mounting plate has a first mounting part. The first fixing part and the first mounting part cooperate to position the mounting plate, fixing it to the fixing plate. The first mounting part and the mounting plate are connected by an elastic segment. The elastic segment arches upward, forming a deformation zone between itself and the mounting plate. The first mounting part and the rubber cotton head do not contact each other. When the first mounting part or the elastic segment is subjected to force, it deforms towards the deformation zone, causing the first mounting part to change position vertically and release its vertical positioning from the first fixing part. The rubber cotton head can be detached from the fixing plate horizontally. The fixing plate has a limiting part below the first fixing part. The limiting part restricts the movement distance of the first mounting part and guides the first mounting part to detach from the fixing plate through the disassembly channel between the first fixing part and the limiting part. Existing rubber cotton heads tend to harden and become undeformable after drying out. The design of the elastic segment and deformation zone allows the elastic segment to deform towards the deformation zone, regardless of whether the rubber cotton head is in a moist and deformable state or a dry and undeformable state. This causes a vertical position change in the first mounting part, thereby altering the fit between the first mounting part and the first fixing part for disassembling the rubber cotton head. The limiting part restricts the vertical movement or deformation range of the first mounting part, preventing the elastic segment from breaking and guiding the movement of the first mounting part during installation and disassembly.

[0006] Preferably, when the adhesive cotton head is fixedly installed with the fixing plate, the limiting part is located in the deformation zone, and the first mounting part and the limiting part have overlapping portions in the vertical plane. During the deformation stage of the elastic segment before the overall movement of the mounting plate and during the lateral movement and disassembly process, the limiting part can play a supporting, limiting and guiding role for the first mounting part.

[0007] Preferably, the limiting part and the mounting plate are located at the same height, and the length of the deformation zone is greater than the length of the first mounting part or the disassembly channel. When the first mounting part completely passes through the disassembly channel to achieve separation, the limiting part is still located in the deformation zone. During the disassembly of the cotton head, the separation of the first mounting part and the disassembly channel, as well as the separation of the limiting part and the mounting plate, must be satisfied simultaneously. The deformation zone provides space for the separation between the limiting part and the mounting plate, and the length of the deformation zone is set to correspond to the length of the elastic segment. Extending the length of the deformation zone and the elastic segment makes the disassembly of the cotton head easier.

[0008] Preferably, the bottom of the limiting part is in contact with the cotton head and cooperates with the cotton head to provide vertical support.

[0009] Preferably, the mounting plate has a groove on the side corresponding to the elastic segment and the first mounting part. During installation and removal of the adhesive head, the limiting part can enter the groove, and the first mounting part protrudes from the side of the elastic segment. The width of the groove corresponding to the position of the first mounting part is smaller than the width corresponding to the position of the elastic segment. When the first mounting part separates from the removal channel, the limiting part separates from the groove at the position of the elastic segment. The cooperation and movement of the first mounting part and the limiting part are arranged on the side, offset from the position and movement of the elastic segment, so that the functions of the two parts do not interfere with each other. With the groove of corresponding width, the limiting part can also separate from the wider groove at the same time as the first mounting part separates from the removal channel, thereby realizing the removal of the adhesive head.

[0010] Preferably, the fixing plate has a long through hole running vertically, and a movable sliding plate is provided on the long through hole. The lower end of the sliding plate passes downward through the long through hole and abuts against the elastic segment or the push rod on the elastic segment. The movement of the sliding plate causes the elastic segment to deform towards the deformation zone. The first mounting part is released from the first fixing part, and the elastic segment deforms downward to the position where the first mounting part contacts the limiting part. The sliding plate can still cooperate with the elastic segment or the push rod. By utilizing the coordinated movement between the sliding plate and the elastic segment or push rod, the adhesive cotton head can be removed without contact, achieving hands-free removal. However, due to the limited space between the mounting plate and the fixed plate, the length of the elastic segment and push rod cannot be extended. Furthermore, the mounting plate is made entirely of thin plastic, making it susceptible to deformation under stress. During the sliding plate's push against the elastic segment or push rod, the elastic segment, mounting plate, and even the adhesive cotton head will deform downwards. If the deformation of the elastic segment is too large, it can cause the elastic segment or push rod to move too far downwards, leading to lateral disengagement between the sliding plate and the elastic segment or push rod. The sliding plate will then be positioned at the front end of the movement direction, unable to push further. The mounting plate and the rubber head can be moved laterally for disassembly, and the sliding plate is also difficult to retract behind the push rod or the elastic section. At the same time, when the rubber head hardens, the sliding plate cannot deform the rubber head. If there is no limiting part, the elastic section is prone to excessive deformation during the pushing process of the sliding plate, causing the sliding plate to be above the push rod or the elastic section, or even beyond the push rod or the elastic section and in front of it. The setting of the limiting part limits the downward movement range of the elastic section, so that when the elastic section is at the maximum deformation and movement position, the sliding plate can still cooperate with the elastic section or the push rod laterally to push, avoiding the situation where the sliding plate is above or even in front of the push rod or the elastic section, causing the sliding plate and the push rod or the elastic section to jam.

[0011] Preferably, the push rod or the elastic segment is provided with a first guide portion, and the sliding plate moves along the first guide portion to push and push, so that the elastic segment gradually deforms towards the deformation zone.

[0012] Preferably, the first mounting part is provided with a second guide part. The push rod moves along the elongated hole, and the second guide part and the first fixing part move to push and push, causing the elastic segment to gradually deform towards the deformation zone. The slope of the first guide part or the second guide part is used to convert the horizontal pushing force applied by the user into downward deformation of the elastic segment, so as to realize the removal of the cotton head.

[0013] Preferably, a clearance area is provided between the first fixing part and the fixing plate. When the mounting plate and the fixing plate are installed and removed, the first fixing part is supported above the first mounting part, and the clearance area provides clearance for the horizontal movement of the push rod. To facilitate the cooperation between the push rod and the sliding plate or the user's finger, the push rod is designed to extend upward to near the position of the elongated hole. The clearance area prevents the second fixing part from obstructing the movement of the push rod when the adhesive head is installed and removed.

[0014] Preferably, the mop handle is also included, with a support base at its lower end. A support rod is rotatably connected below the support base, and the other end of the support rod is connected to the fixing plate. Two support rods and two fixing plates are provided, rotatably connected to each other via a connector. Two mounting plates are provided at positions corresponding to the two fixing plates for the sponge head. A handle is rotatably connected to the middle of the mop handle, and the handle is connected to the connector via a pull rod. Rotating the handle causes the sponge head to fold towards the support base. The sponge head is squeezed and dehydrated by pulling it with the handle to fold it in half.

[0015] Preferably, the fixing plate is further provided with a second fixing part, and the mounting plate is further provided with a second mounting part. During installation, the second fixing part and the second mounting part slide horizontally and insert into each other to cooperate and position themselves in the vertical direction. The cooperation of the two sets of fixing parts and mounting parts makes the installation of the cotton head more stable.

[0016] The advantages of this utility model are as follows: The elastic segment and deformation zone allow the elastic segment to deform towards the deformation zone regardless of whether the cotton head is in a moist, deformable state or a dry, non-deformable state, causing a vertical position change in the first mounting part. This alters the fit between the first mounting part and the first fixing part, allowing for the disassembly of the cotton head. The limiting part restricts the vertical movement or deformation range of the first mounting part, preventing breakage of the elastic segment and guiding the movement of the first mounting part during installation and disassembly. The limiting part also restricts the downward movement range of the elastic segment, ensuring that even when the elastic segment is at its maximum deformation and movement position, the sliding plate can still engage laterally with the elastic segment or push rod, preventing the sliding plate from being positioned above or even in front of the push rod or elastic segment, thus avoiding a jamming situation where the sliding plate and push rod or elastic segment are locked together.

[0029] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so that the implementation of this utility model can be fully understood and carried out based on how technical means are used to solve technical problems and achieve technical effects.

[0030] This utility model uses certain terms to refer to specific components. Those skilled in the art will understand that this specification and claims do not distinguish components by differences in name, but rather by differences in function. It should be noted that, unless otherwise specified, when a component is described as "provided with," "located on," or "located on" another component, it can mean directly provided with or located on another component, or it may also mean there is a component in between; it can be an integral structure or a separate structure. When a component is described as "connected" to another component, it can mean a direct connection or a connection through a component in between; it can be an integral connection, a separate connection, or a contact fit. When a component is described as "located on another component," it does not necessarily mean that the component is located above or on top of the other component; it can be in other positions. The terms "upper," "lower," "left," "right," "high," "lower," and similar expressions used herein are based on the normal placement state of the product and are merely for illustrative purposes. The term "multiple" used herein refers to two or more items. The terms "vertical" and "horizontal" used in this article refer to a state that is roughly vertical or roughly horizontal within a reasonable margin of error, and do not necessarily have to be extremely precise.

[0031] like Figure 1-12 A quick-release structure for a mop head includes a mop handle 1, with a mop head directly or indirectly connected to the lower end of the mop handle 1. The mop head includes a fixing plate 2 and a mop head 3. The mop head 3 is provided with a mounting plate 4. The fixing plate 2 is provided with a first fixing part 5 and a second fixing part 6. The mounting plate 4 is provided with a first mounting part 7 and a second mounting part 8. When the fixing plate 2 and the mounting plate 4 are fixedly installed, the first fixing part 5 and the first mounting part 7 are positioned in a horizontal direction, and the second fixing part 6 and the second mounting part 8 are positioned in a vertical direction. A push rod 10 is provided between the fixing plate 2 and the mounting plate 4. The push rod 10 is connected to the mounting plate 4 through an elastic section 11. The elastic section 11 arches upward to form a deformation zone 12 between itself and the mounting plate 4. The push rod 10 can drive the elastic section 11 to deform towards the deformation zone 12, causing the first mounting part 7 to shift in the vertical direction and release the vertical positioning of the first fixing part 5. The second fixing part 6 separates from the second mounting part 8, allowing the mop head 3 to be removed from the fixing plate 2 in a horizontal direction.

[0032] Because the mounting plate 4 and the fixing plate 2 are both limited in the vertical and horizontal directions, the adhesive cotton head 3 is unlikely to fall off the fixing plate 2 even if it is bumped or knocked during daily use.

[0033] In this embodiment, as Figure 8-9The mop is a foldable sponge mop. The lower end of the mop handle 1 is provided with a support base 13. A support rod 14 is rotatably connected to each side of the support base 13. The lower end of each support rod 14 is connected to a fixing plate 2. The two fixing plates 2 are rotatably connected to each other through a connector 15. A handle 16 is rotatably connected to the middle of the mop handle 1. The handle 16 is connected to the connector 15 through a pull rod 17. When in use, the sponge head 3 is installed under the fixing plate 2. The handle 16 is flipped upward. The handle 16 drives the connector 15 to move upward through the pull rod 17, so that the two fixing plates 2 and the support rods 14 are flipped upward, so that the sponge head 3 is folded in half along the middle and squeezed to remove water.

[0034] In other embodiments, the mop can also be configured as a flat plywood mop (not shown in the figure), with the lower end of the mop handle 1 rotatably connected to the fixing plate 2, and the plywood head 3 mounted on the fixing plate 2 via the mounting plate 4. A squeezing device for cleaning or dehydrating the plywood head 3 is provided on the mop handle 1 or the matching mop bucket.

[0035] It should be noted that in this embodiment, the relevant direction and position refer to the direction when the sponge mop is placed vertically, such as... Figure 8 As shown, the vertical direction is the axis direction of the mop handle 1, the horizontal direction is the direction perpendicular to the mop handle 1, and the left and right directions are the extension directions of the cotton head 3.

[0036] In the above embodiment, the mounting plate 4 is made of a plastic sheet, and the push rod 10, the elastic segment 11 and the mounting plate 4 are integrally formed. The elastic segment 11 is set as an upwardly arched sheet, and the push rod 10 is located at the top of the elastic segment 11. The area below the push rod 10, that is, the angle area between the elastic segment 11 and the mounting plate 4, forms the deformation zone 12. When subjected to external force, the elastic segment 11 deforms downward into the deformation zone 12 to drive the push rod 10 to move downward. The first mounting part 7 can be a component installed on the push rod 10 or the elastic segment 11, or it can be a part of the push rod 10 or the elastic segment 11 forming the first mounting part 7, so that there is an upper and lower gap between the first mounting part 7 and the main body of the mounting plate 4 or between the cotton head 3. The first mounting part 7 does not directly contact the cotton head 3. When the elastic segment 11 deforms into the deformation zone, there is no need to consider the dryness, wetness and softness of the cotton head 3. The elastic segment 11 can always deform, thereby improving the disadvantage that the first mounting part 7 cannot deform into the cotton head 3 when the cotton head 3 dries and hardens.

[0037] To avoid excessive deformation of the elastic segment 11 towards the deformation zone 12, such as Figure 2-36-7. In this embodiment, the fixing plate 2 is provided with a limiting part 9, which is located below the first fixing part 5. A disassembly channel 23 is formed between the limiting part 9 and the first fixing part 5. The thickness of the disassembly channel 23 is adapted to the thickness of the first mounting part 7. During the disassembly process, the elastic segment 11 first enters the deformation zone 12 downward and deforms and bends until the first mounting part 7 and the disassembly channel 23 are at the same height or fit with the limiting part 9. At this time, the first mounting part 7 separates from the first fixing part 5, and the first mounting part 7 and the mounting plate 4 move horizontally along the disassembly channel 23. After the first mounting part 7 moves to the end of the disassembly channel 23, the cotton head is disassembled. The setting of the limiting part 9 can limit the deformation range of the elastic segment 11 and the downward movement range of the first mounting part 7, avoid the elastic segment 11 from breaking due to excessive deformation, and also guide the horizontal movement of the first mounting part 7.

[0038] Preferably, when the cotton head 3 is fixedly installed with the fixing plate 2, the limiting part 9 is located in the deformation zone 12, and the first mounting part 7 and the limiting part 9 have overlapping parts on the vertical plane. During the initial stage of the first mounting part 7's movement and before the disassembly is completed, the first mounting part 7 is always limited and guided by the limiting part 9, so as to prevent the first mounting part 7 from moving downward to the height that is horizontally overlapping with the limiting part 9, and the first mounting part 7 and the limiting part 9 from hitting each other and being unable to move horizontally.

[0039] In this embodiment, the limiting part 9, the first fixing part 5, and the fixing plate 2 are integrally formed, and the limiting part 9 is located directly below the first fixing part 5. The limiting part 9 and the mounting plate 4 are at the same height. The length of the deformation zone 12 is greater than the length of the first mounting part 7 or the disassembly channel 23. When the first mounting part 7 passes through the disassembly channel 23 to achieve separation, the limiting part 9 is still located in the deformation zone 12. During the disassembly process of the cotton head 3, the separation of the first mounting part 7 and the disassembly channel 23 and the separation of the limiting part 9 and the mounting plate 4 must be satisfied simultaneously. The deformation zone 12 can provide space for the separation between the limiting part 9 and the mounting plate 4, and the length of the deformation zone 12 is set to correspond to the length of the elastic segment 11. The extension of the length of the deformation zone 12 and the elastic segment 11 can make the disassembly of the cotton head 3 easier.

[0040] Preferably, the bottom of the limiting part 9 is attached to the cotton head 3 and cooperates with the cotton head 3 to provide vertical support.

[0041] To facilitate the deformation of the elastic segment 11 under stress, grooves 18 are provided between the elastic segment 11 and the mounting plate 4 on both sides. The grooves 18 extend to the position of the first mounting part 7. In this embodiment, the mounting plate 4 is provided with a vertically penetrating deformation hole 19. The deformation hole 19 is located directly below the elastic segment 11 and the first mounting part 7. The length of the deformation hole 19 extends from the connection between the elastic segment 11 and the mounting plate 4 towards the first mounting part 7 and is located on the outside of the first mounting part 7. The width of the deformation hole 19 is greater than the width of the elastic segment 11 and the width of the first mounting part 7. The width of the first mounting part 7, the width difference between the deformation hole 19 and the elastic segment 11 and the first mounting part 7 forms a groove 18, and the gap between the elastic segment 11 and the deformation hole 19 in the vertical direction forms a deformation zone 12. During the installation and disassembly of the cotton head 3, the limiting part 9 can enter the groove 18. The first mounting part 7 protrudes from the side of the elastic segment 11, and the width of the groove 18 corresponding to the position of the first mounting part 7 is smaller than the width of the corresponding position of the elastic segment 11. When the first mounting part 7 separates from the disassembly channel 23, the limiting part 9 separates from the groove 18 at the position of the elastic segment 11. The cooperation and movement of the first mounting part 7 and the limiting part 9 are set on the side, offset from the position and movement of the elastic segment 11, so that the functions of the two parts do not interfere with each other. The groove 18 is set with a corresponding width. At the same time that the first mounting part 7 separates from the disassembly channel 23, the limiting part 9 can also separate from the wider groove 18 to realize the disassembly of the cotton head 3.

[0042] To allow for the disassembly of the adhesive cotton head 3 without getting your hands dirty, the first mounting part 7 is moved by a sliding plate 21 installed on the fixed plate 2. Specifically, as follows: Figure 2-3 The fixed plate 2 is provided with a long strip hole 20 that runs vertically through it. A movable sliding plate 21 is provided on the long strip hole 20. The lower end of the sliding plate 21 passes through the long strip hole 20 downward and abuts against the push rod 10 or the elastic segment 11. The sliding plate 21 moves and causes the elastic segment 11 to deform towards the deformation zone 12. The first mounting part 7 is released from the first fixed part 5, and the elastic segment 11 deforms downward to the position where the first mounting part 7 contacts the limiting part 9. The sliding plate 21 can still cooperate with the elastic segment 11 or the push rod 10 to move.

[0043] The sliding plate 21 and the limiting part 9, in addition to their disassembly guiding function, also have the following functions: When the cotton head 3 is in a moist and soft state, the sliding plate 21 drives the first mounting part 7 to detach from the first fixing part 5, and drives the mounting plate 4 to move and the cotton head 3 to deform until the cotton head 3 is removed from the fixing plate 2; however, when the cotton head 3 is dehydrated and hardened, the sliding plate 21 drives the first mounting part 7 to detach from the first fixing part 5, the hardness of the cotton head 3 cannot deform, and the mounting plate 4 cannot move. If the limiting part 9 is not provided, such as Figure 4 If the sliding plate 21 is pushed further, the elastic segment 11 will deform excessively, causing the push rod 10 or the higher elastic segment 11 to be located below the sliding plate 21, resulting in jamming and inability to cooperate. Figure 5Even if the sliding plate 21 passes over the push rod 10 or the high elastic section 11 and is located in front of the push rod 10 or the high elastic section 11 in the disassembly direction, after losing the pushing force of the sliding plate 21, the elastic section 11 deforms and resets. The push rod 10 or the high elastic section 11 and the sliding plate 21 are at approximately the same height. The sliding plate 21 is blocked by the push rod 10 or the high elastic section 11 and cannot move backward to reset to the position that cooperates with the push rod 10 or the high elastic section 11. If the sliding plate 21 is to be moved to the cooperation position, a tool is needed to pry the elastic section 11 from the outside to deform it to a height lower than the sliding plate 21, so that the sliding plate 21 can move backward to the position that cooperates with the push rod 10 or the high elastic section 11. In this embodiment, the limiting part 9 is provided so that when the cotton head 3 hardens and cannot be deformed, the limiting part 9 prevents the elastic segment 11 from deforming excessively, so that the first mounting part 7 is always above the limiting part 9, and the sliding plate 21 is always in a mating position with the push rod 10 at approximately the same height. The sliding plate 21 cannot move above the push rod 10, or even pass over the push rod 10 and be in front of the push rod 10 for disassembly and movement, thereby avoiding the situation where the sliding plate 21 and the push rod 10 malfunction and are difficult to reset.

[0044] Specifically, the middle part of the sliding plate 21 is installed on the elongated hole 20 by a spring clip, so that the sliding plate 21 can move horizontally in the elongated hole 20. The push rod 10 or the elastic section 11 is provided with a first guide part 22. The lower end of the sliding plate 21 is located above the first guide part 22 and abuts against the first guide part 22. The sliding plate 21 moves horizontally to contact the first guide part 22 at different positions. The elastic section 11 is subjected to force and deforms and bends towards the deformation zone 12 until the first mounting part 7 disengages from the first fixing part 5. The mounting plate 4 moves horizontally as a whole, and the first mounting part 7 disengages from the first fixing part 5. At this time, the mounting plate 4 separates from the fixing plate 2.

[0045] Preferably, the first fixing part 5 and the first mounting part 7 are located on the outside of the push rod 10. A clearance area 24 is provided between the first fixing part 5 and the fixing plate 2. When the mounting plate 4 and the fixing plate 2 are installed and removed, the first fixing part 5 is supported above the first mounting part 7, and the clearance area 24 provides clearance for the horizontal movement of the push rod 10.

[0046] In the above embodiment, the cotton head 3 is provided with two mounting plates 4 at the positions corresponding to the two fixing plates 2. Each fixing plate 2 and the corresponding mounting plate 4 are provided with a quick-release structure. There is a gap between the two mounting plates 4. The gap is located below the connector 15. The handle 16 pulls the connector 15 to move upward. The cotton head 3 can be folded in half and squeezed out of water at the position of the gap.

[0047] Preferably, the second mounting part 8 and the second fixing part 6 are inserted into each other, and the two are inserted along the length direction of the cotton head 3.

[0048] In this embodiment, the two quick-release structures are identical in structure, differing only in installation position and direction. Specifically, as shown... Figure 10 Two sets of quick-release structures are symmetrically arranged along the vertical plane where the mop handle 1 or connector 15 is located. Two push rods 10 are located close to the connector 15, and two sets of second fixing parts 6 and second mounting parts 8 are located away from the connector 15. A baffle 27 is provided at the far end of the second fixing part 6. The baffle 27 prevents the second mounting part 8 from detaching from the second fixing part 6 in the direction away from the connector 15 after installation. The two push rods 10 are set close to the connector 15 to shorten the distance between the two push rods 10, making it convenient for the user to control the movement of the two push rods 10 with one hand at the same time. When disassembling the cotton head 3, the user can choose to disassemble both sets of quick-release structures at the same time, or choose to disassemble one set of quick-release structures first and then disassemble the other set of quick-release structures. Regardless of whether the disassembly is done simultaneously or sequentially, each mounting plate 4 must cause the cotton head 3 below the connector 15 to deform before the mounting plate 4 can move laterally to the position where the first mounting part 7, the second mounting part 8, the first fixing part 5, and the second fixing part 6 are separated. Similarly, regardless of whether the installation is done simultaneously or sequentially, the cotton head 3 below the connector 15 must be squeezed and deformed before the two mounting plates 4 can be installed on the fixing plate 2.

[0049] The existing PVA head 3 is soft, deformable, and bendable after being soaked in water, but becomes hard and indeformable after drying out. Based on the characteristics of the PVA head 3 material, when the two quick-release structures are installed and removed in opposite directions, only the soft PVA head 3 can be installed and removed. If the PVA head 3 becomes dry and hard, the PVA head 3 between the two mounting plates 4 cannot be deformed or bent, and the two mounting plates 4 cannot be installed and removed.

[0050] To allow for installation and removal of the foam head 3 in both soft and hardened states, the structure of the two quick-release mechanisms can be adjusted, such as... Figure 11 By adjusting the movement direction of the two quick-release structures to the same direction, the two mounting plates 4 are installed and removed in the same direction, and their displacement distances are the same. The adhesive head 3 can be installed and removed without deformation or bending. Specifically, one quick-release structure still uses the above-described structure, but the directions of the push rod 10, elastic segment 11, first fixing part 5, and first mounting part 7 of the other quick-release structure are mirrored, so that the movement direction and length of the two push rods 10, two elastic segments 11, and two mounting plates 4 are the same during installation and removal. During installation and removal, the adhesive head 3 between the two mounting plates 4 does not need to deform or bend, thus enabling the installation and removal of the hardened adhesive head 3.

[0051] In the above embodiment, a squeezing plate 26 is movably connected to the outer side of the fixing plate 2. The upper end of the squeezing plate 26 is connected to the support rod 14. When the cotton head 3 is folded in half to squeeze out water, the squeezing plate 26 moves along the length direction of the fixing plate 2 to squeeze the end of the cotton head 3.

[0052] Preferably, the support rod 14 and the dewatering plate 26 are integrally formed or fixedly connected. The dewatering plate 26 is movably connected to the fixed plate 2 through the support rod 14, so that the support rod 14 and the dewatering plate 26 can move and flip relative to the fixed plate 2.

[0053] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

Claims

1. A quick-release structure for a rubber cotton head, comprising a fixing plate and a rubber cotton head, wherein the rubber cotton head is provided with a mounting plate, the fixing plate is provided with a first fixing part, and the mounting plate is provided with a first mounting part, wherein the first fixing part and the first mounting part cooperate to position and fix the mounting plate on the fixing plate, characterized in that... The first mounting part is connected to the mounting plate by an elastic segment. The elastic segment arches upward to form a deformation zone with the mounting plate. The first mounting part does not contact the cotton head. The first mounting part or the elastic segment deforms towards the deformation zone under force, causing the first mounting part to change position in the vertical direction and release its vertical positioning from the first fixing part. The fixing plate has a limiting part below the first fixing part. The limiting part restricts the movement distance of the first mounting part and guides the first mounting part to detach from the fixing plate through the disassembly channel between the first fixing part and the limiting part.

2. The quick-release structure for the adhesive cotton head according to claim 1, characterized in that, When the cotton head is fixedly installed with the fixing plate, the limiting part is located in the deformation zone, and the first mounting part and the limiting part have overlapping parts in the vertical plane.

3. The quick-release structure for the adhesive cotton head according to claim 2, characterized in that, The limiting part and the mounting plate are at the same height. The length of the deformation zone is greater than the length of the first mounting part or the disassembly channel. When the first mounting part passes through the disassembly channel to achieve separation, the limiting part is still located in the deformation zone.

4. The quick-release structure for the adhesive cotton head according to claim 3, characterized in that, The bottom of the limiting part is attached to the cotton head and cooperates with the cotton head to provide vertical support.

5. The quick-release structure for the adhesive cotton head according to claim 3, characterized in that, The mounting plate has a groove on the side corresponding to the elastic segment and the first mounting part. During the installation and disassembly of the cotton head, the limiting part can enter the groove. The first mounting part protrudes from the side of the elastic segment, and the width of the groove corresponding to the position of the first mounting part is smaller than the width corresponding to the position of the elastic segment. When the first mounting part is separated from the disassembly channel, the limiting part separates from the groove at the position of the elastic segment.

6. The quick-release structure for the adhesive cotton head according to claim 5, characterized in that, The fixed plate has a long through hole running vertically through it. A movable sliding plate is provided on the long through hole. The lower end of the sliding plate passes downward through the long through hole and abuts against the elastic segment or the push rod on the elastic segment. The sliding plate moves and causes the elastic segment to deform towards the deformation zone. The first mounting part is released from the first fixed part, and the elastic segment deforms downward to the position where the first mounting part contacts the limiting part. The sliding plate can still cooperate with the elastic segment or the push rod to move.

7. The quick-release structure for the adhesive cotton head according to claim 6, characterized in that, The push rod or the elastic segment is provided with a first guide portion, and the sliding plate moves along the first guide portion to push and push, so that the elastic segment gradually deforms towards the deformation zone; Alternatively, the first mounting part may be provided with a second guide part, the push rod may move along the elongated hole, and the second guide part and the first fixing part may move and push, so that the elastic segment gradually deforms toward the deformation zone.

8. The quick-release structure for the adhesive cotton head according to claim 7, characterized in that, A clearance area is provided between the first fixing part and the fixing plate. When the mounting plate and the fixing plate are installed and removed, the first fixing part is supported above the first mounting part, and the clearance area provides clearance for the horizontal movement of the push rod.
