[0001] The utility model relates to the technical field of daily household cleaning, in particular to a rubber cotton mop. Background Art

[0002] Mop is an indispensable household cleaning tool. Rubber cotton mop is used by more and more families because of its strong water absorption and ability to fully meet the needs of cleaning work.

[0003] A commonly used roller collodion mop includes a mop rod, a collodion head, at least two rollers arranged at the end of the mop rod for squeezing the collodion head, and a pull rod for pulling the collodion head to move between the at least two rollers, and the collodion head is connected to the lower end of the pull rod.

[0004] If the fixation of the collodion head and the pull rod is not reliable, the collodion head and the pull rod may easily separate when the pull rod pulls the collodion head to move between at least two rollers, resulting in the collodion mop being unable to continue to be used normally and a poor user experience. Utility Model Content

[0005] In view of this, the utility model provides a collodion mop to solve the problem in the prior art that the collodion head is easily separated from the pull rod when moving.

[0006] The utility model provides a collodion mop, which comprises a mop rod, a squeezing part, a pull rod and a collodion head;

[0007] The squeezing part is arranged at the end of the mop rod, the pull rod is used to connect with the collodion head, and the pull rod is movably connected with the mop rod. When the pull rod moves along the axial direction of the mop rod, the collodion head is driven to move relative to the squeezing part, so that the squeezing part squeezes and cleans the collodion head.

[0008] The end of the pull rod is provided with a mounting seat for mounting a rubber cotton head, and the rubber cotton head is provided with an assembly seat;

[0009] The mounting seat and the assembly seat can rotate relative to each other from a first position where they are at least partially misaligned to a second position where they at least partially overlap, and in the first position the mounting seat and the assembly seat can be separated along the axial direction of the mop rod, and in the second position the mounting seat and the assembly seat limit each other along the axial direction of the mop rod.

[0010] Beneficial effect: by setting a mounting seat at the end of the pull rod and an assembly seat on the rubber cotton head, when the mounting seat and the assembly seat are relatively rotated to a second position where the two are at least partially overlapped, the mounting seat and the assembly seat are mutually limited along the axial direction of the mop rod, thereby realizing effective fixation between the rubber cotton head and the pull rod. The rubber cotton head and the pull rod are connected by the relative rotation of the mounting seat and the assembly seat, so that the connection method of the two is simple and reliable, and the installation is relatively convenient and quick. The mounting seat and the assembly seat are mutually limited along the axial direction of the mop rod, which can effectively prevent the rubber cotton head from being separated from the pull rod when moving, improves the reliability of the rubber cotton mop when in use, and provides a better user experience. At the same time, the installation of the rubber cotton head and the pull rod is realized by the relative rotation of the mounting seat and the assembly seat, the force displacement is short, and it is convenient for users to operate. In addition, there is no need for users to increase the force during the installation process, which avoids the problem of excessive installation due to excessive force and the need for repeated installation, and provides a better user experience.

[0011] In an optional embodiment, the mounting seat is provided with a connecting portion, and the assembly seat is provided with a matching portion;

[0012] When the mounting seat and the assembly seat are relatively rotated to the second position, the connecting portion and the matching portion are staggered and matched, and after the staggered matching, the connecting portion and the matching portion limit each other along the axial direction of the mop rod.

[0013] Beneficial effect: by arranging a connecting part on the mounting seat and a matching part on the assembly seat, by controlling the relative rotation of the mounting seat and the assembly seat, the connecting part and the matching part can be staggered to achieve effective fixation between the rubber cotton head and the pull rod. The connection method is simple and efficient, and after the staggered matching, the connecting part and the matching part limit each other along the axial direction of the mop rod, thereby effectively preventing the rubber cotton head from falling off, and effectively solving the problem that the rubber cotton head is easy to fall off when installed in the way of slider slot etc. in the prior art.

[0014] In an optional embodiment, one of the connecting portion and the matching portion is a connecting groove, and the other of the connecting portion and the matching portion is a matching block;

[0016] The mounting seat and the assembly seat rotate relative to each other, so that the protrusion of the matching block is inserted into the connecting groove from the opening, and the contraction portion cooperates with the shrinkage portion, so that the protrusion and the shrinkage portion limit each other along the axial direction of the mop rod.

[0017] Beneficial effects: The connecting portion and the matching portion adopt the form of a connecting groove and a matching block, which has a simple structure. The connecting groove facilitates the protrusion of the matching block to enter the connecting groove when the connecting portion and the matching portion rotate relative to each other through the opening arranged in the circumferential direction, thereby realizing the connection and fixation of the two. In addition, the connecting groove and the matching block adopt the arrangement of a contraction portion and a necking portion, so that the protrusion and the necking portion can limit each other along the axial direction of the mop rod, thereby effectively preventing the protrusion from escaping from the connecting groove, and further improving the stability and reliability of the connection between the connecting portion and the matching portion.

[0018] In an optional embodiment, the protruding portion of the matching block is a matching plate extending radially along the mop rod, and the contracted portion is a matching column disposed between the matching plate and one of the mounting seat or the assembly seat;

[0019] The connecting groove includes a groove body extending radially along the mop rod, the groove body has an opening on at least one side along the circumference of the mop rod, and a convex plate extending radially along the mop rod is arranged on one end of the two side walls of the groove body along the axial direction of the mop rod away from the other of the mounting seat or the assembly seat, and a constricted portion is formed between the two convex plates.

[0020] Beneficial effect: By setting two convex plates on the two side walls of the groove body, and having a set interval between the two convex plates, a necking portion is formed between the two convex plates, so that the protrusion can be effectively limited in the axial direction of the mop rod. The necking portion is formed by the above two convex plates, and the structure is simple and easy to process and form.

[0021] In an optional embodiment, the matching block is T-shaped or L-shaped, and the connecting groove is correspondingly configured as a T-shaped groove or an L-shaped groove.

[0022] Beneficial effects: The matching block adopts a T-shaped block or an L-shaped block, and the connecting groove is correspondingly set to a T-shaped groove or an L-shaped groove, so that the matching block and the connecting groove can form a necking part, a protruding part and a contraction part by utilizing their own special shapes, further simplifying the structure and processing technology, and the T-shaped or L-shaped matching block and the connecting groove can form a good limiting effect when they cooperate with each other, and are not easy to unhook.

[0023] In an optional implementation, after the mounting seat and the assembly seat are staggered and matched, the connecting portion and the matching portion are snap-fitted.

[0024] Beneficial effect: After the installation seat and the assembly seat are staggered and matched, the connecting part and the matching part can be mutually engaged, which can not only form a good limiting effect but also facilitate disassembly and assembly.

[0025] In an optional embodiment, when one of the connecting portion and the matching portion is a connecting groove and the other is a matching block;

[0026] One of the groove wall of the connecting groove and the side wall of the matching block is provided with a limiting protrusion, and the other is provided with a limiting groove;

[0027] After the mounting seat and the assembly seat are interlaced and matched, the limiting protrusion is snapped into the limiting groove, so that the connecting part and the matching part limit each other along the circumference of the mop rod.

[0028] Beneficial effect: by setting the limiting protrusions and limiting grooves on the groove wall of the connecting groove and the side wall of the matching block, when the mounting seat and the assembly seat are staggered and matched, the connecting groove is engaged with the matching block, and the limiting protrusion can also be connected to the limiting groove. Through the cooperation of the limiting protrusion and the limiting groove, the matching block and the connecting groove can limit each other in the circumferential direction of the mop rod after matching, so that the matching block and the connecting groove can be stably maintained in the current clamping state, thereby effectively avoiding the problem that the matching block is easily detached from the connecting groove when the rubber cotton head or the mop rod is subjected to a small external force, such as scratching other parts or being triggered by the user, thereby reducing the probability of false triggering and improving the stability and reliability of the rubber cotton head after installation.

[0029] In an optional embodiment, two T-shaped matching blocks are provided at both ends of the mounting seat, and two T-shaped connecting grooves are provided at both ends of the assembly seat;

[0030] The outer side walls of the contraction parts of the two T-shaped matching blocks are provided with limiting protrusions, and the inner side walls of the contraction parts of the two T-shaped connecting grooves are provided with limiting grooves;

[0031] The mounting seat and the assembly seat rotate relative to each other so that the two T-shaped matching blocks are respectively staggeredly matched with the two T-shaped connecting grooves, so that the limiting protrusion is clamped into the limiting groove.

[0032] Beneficial effect: By setting up two T-shaped matching blocks and two T-shaped connecting grooves, the stability and reliability of the matching between the rubber cotton head and the pull rod can be further improved. In addition, by setting limiting protrusions on the outer walls of the contraction part of the two T-shaped matching blocks and corresponding limiting grooves on the inner walls of the shrinkage part of the two T-shaped connecting grooves, the entire rubber cotton head can be limited from both sides, further reducing the risk of the rubber cotton head accidentally falling off the pull rod due to accidental triggering.

[0131] In the related art, in order to facilitate the replacement of the cotton wool head, the pull rod and the cotton wool head can be detachably connected, but the existing detachable connection is usually in the form of a slot and a slider, that is, one of the slots or sliders is set on the cotton wool head, and the other of the slots or sliders is set on the connecting block under the pull rod.

[0132] When installing the sponge head, the user only needs to insert the slider into the slot, and the assembly is relatively convenient, but there are the following defects: in order to ensure that the force on both ends of the sponge head is even when the pull rod pulls the sponge head, the slot is usually set longer, and the corresponding plug block is also set longer. Therefore, when the user installs the sponge head by plugging, the force displacement is also longer, that is, the user needs to insert the end of the plug block into the opening of the slot first, and then continue to move the sponge head until the first inserted end moves to the other end of the slot. The force displacement is the same as the length of the slot. The longer the force displacement, the more inconvenient it is for the user to install. Moreover, when the user is applying force, if the direction of the force is slightly different, it may cause the plug block to be held against the slot, making it impossible to install the rubber cotton head smoothly. At this time, the user will overcome this problem by increasing the force. Although increasing the force can force the plug block to continue to move along the slot, the large force may also cause the plug block to move too fast and fall out of the other end of the slot. The user needs to move the rubber cotton head in the opposite direction again to complete the installation. That is, due to the uncontrollable installation result, the user will need to move the rubber cotton head back and forth multiple times to achieve the optimal installation state, which results in a poor user experience.

[0133] Combine the following Figures 1 to 19 , describing an embodiment of the utility model.

[0134] According to an embodiment of the utility model, the utility model provides a collodion mop, which includes a mop rod 10, a squeezing portion 20, a pull rod 30 and a collodion head 40; the squeezing portion 20 is arranged at the end of the mop rod 10, the pull rod 30 is used to connect with the collodion head 40, and the pull rod 30 is movably connected with the mop rod 10, when the pull rod 30 moves along the axial direction of the mop rod 10, the collodion head 40 is driven to move relative to the squeezing portion 20, so that the squeezing portion 20 squeezes and cleans the collodion head 40; a mounting seat 31 for mounting the collodion head 40 is arranged at the end of the pull rod 30, and an assembly seat 41 is arranged on the collodion head 40; the mounting seat 31 and the assembly seat 41 can rotate relative to each other from a first position where the two are at least partially misaligned to a second position where the mounting seat 31 and the assembly seat 41 at least partially overlap, and in the first position, the mounting seat 31 and the assembly seat 41 can be separated along the axial direction of the mop rod 10, and in the second position, the mounting seat 31 and the assembly seat 41 are mutually limited along the axial direction of the mop rod 10.

[0135] The mounting seat 31 and the assembly seat 41 can be completely or partially misaligned in the first position. In the first position, because the two are at least partially misaligned, no limit is formed in the axial direction of the mop rod 10, that is, the two can be separated along the axial direction; the mounting seat 31 and the assembly seat 41 can be partially or completely overlapped in the second position, and because they are at least partially overlapped in the second position, a limit can be formed in the axial direction of the mop rod 10 to prevent the two from being separated along the axial direction.

[0136] Optionally, the at least partially offset first position of the mounting seat 31 and the assembly seat 41 may be a position where the mounting seat 31 and the assembly seat 41 extend along different radial directions of the mop rod 10; when the two are relatively rotated to the second position, the two may be arranged to extend along the same radial direction of the mop rod 10. The rotation plane formed by the relative rotation of the mounting seat 31 and the assembly seat 41 may be substantially parallel to the cross section of the mop rod 10.

[0137] Optionally, if the mop rod 10 is a bent rod, the axial and radial directions of the mop rod 10 are both the axial and radial directions of the portion of the mop rod near the collodion head, and the central axis of the mop rod 10 is also the central axis of the portion of the mop rod near the collodion head.

[0138] Optionally, when the mounting seat 31 and the assembly seat 41 are relatively rotated to the second position, the mounting seat 31 and the assembly seat 41 may both be extended along the length direction of the collodion head 40 .

[0139] The rotation axis of the relative rotation of the mounting seat 31 and the assembly seat 41 is parallel to or coincides with the central axis of the mop rod 10. For example, the rotation axis can be located at the end of the mounting seat 31 or the assembly seat 41, and the mounting seat 31 and the assembly seat 41 rotate relative to each other around the end of the mounting seat 31 or the assembly seat 41, and at this time, the rotation axis is parallel to the central axis of the mop rod 10. Specifically, assuming that the rotation axis is located at one end of the mounting seat 31, when the mounting seat 31 and the assembly seat 41 are located at the first position, part of the assembly seat 41 coincides with the end of the mounting seat 31 in the axial direction of the mop rod 10, and the remaining part is misaligned with the mounting seat 31 in the axial direction of the mop rod 10. By relatively rotating around the end of the mounting seat 31, the assembly seat 41 and the mounting seat 31 can be rotated to the second position where both the assembly seat 41 and the mounting seat 31 extend along the length direction of the collodion head 40, and at this time, the two are roughly coincident in the axial direction of the mop rod 10, and are mutually limited along the axial direction of the mop rod 10.

[0140] Alternatively, the rotation axis may be located in the central area of ​​the mounting seat 31 or the assembly seat 41, and the mounting seat 31 and the assembly seat 41 rotate relative to each other around the central area, and at this time, the rotation axis may coincide with the central axis of the mop rod 10; specifically, assuming that the rotation axis is located in the central area of ​​the mounting seat 31, when the mounting seat 31 and the assembly seat 41 are located in the first position, a portion of the assembly seat 41 coincides with the central area of ​​the mounting seat 31 in the axial direction of the mop rod 10, and the remaining portion is misaligned with the mounting seat 31 in the axial direction of the mop rod 10. By relatively rotating around the central area of ​​the mounting seat 31, the assembly seat 41 and the mounting seat 31 can be rotated to the second position where both extend along the length direction of the collodion head 40, and at this time, the two roughly coincide in the axial direction of the mop rod 10, and are mutually limited along the axial direction of the mop rod 10.

[0141] Alternatively, the rotation axis can be located at the end of the collodion head 40, and the mounting seat 31 and the assembly seat 41 rotate relatively around the end of the collodion head 40, and at this time, the rotation axis is parallel to the central axis of the mop rod 10. Specifically, when the mounting seat 31 and the assembly seat 41 are located at the first position, the assembly seat 41 can be completely misaligned with the mounting seat 31 in the axial direction of the mop rod 10, and by relatively rotating around the end of the collodion head 40, the assembly seat 41 and the mounting seat 31 can be rotated to the second position where both extend along the length direction of the collodion head 40, and at this time, the two are roughly overlapped in the axial direction of the mop rod 10, and are mutually limited along the axial direction of the mop rod 10.

[0142] In the above embodiment, by means of the mounting seat 31 provided at the end of the pull rod 30 and the assembly seat 41 provided on the collodion head 40, when the mounting seat 31 and the assembly seat 41 are relatively rotated from a first position detachable along the axial direction of the mop rod 10 to a second position limited along the axial direction, the collodion head 40 and the pull rod 30 can be effectively fixed. The collodion head 40 and the pull rod 30 are connected by the relative rotation and fixing of the mounting seat 31 and the assembly seat 41, so that the connection between the two is simple and reliable, and the installation is relatively convenient and quick. Moreover, the mounting seat 31 and the assembly seat 41 are mutually limited along the axial direction of the mop rod 10, which can effectively prevent the collodion head 40 from being separated from the pull rod 30 when moving, thereby improving the reliability of the collodion mop when in use, and providing a better user experience.

[0143] At the same time, the installation of the cotton wool head 40 and the pull rod 30 is achieved through the relative rotation of the mounting seat 31 and the assembly seat 41. The force displacement is short, which is convenient for user operation. In addition, there is no need for the user to increase the force during the installation process, thus avoiding the problem of excessive installation due to excessive force and the need for repeated installation, and the user experience is better.

[0144] Optionally, when the mounting seat 31 and the assembly seat 41 are located at the first position, the mounting seat 31 and the assembly seat 41 are staggered and intersected; when the mounting seat 31 and the assembly seat 41 are relatively rotated to the second position, the mounting seat 31 and the assembly seat 41 can both extend along the length direction of the collodion head 40.

[0145] like Figures 1 to 15 As shown, in some embodiments of the present invention, a connecting portion 311 is provided on the mounting seat 31, and a matching portion 411 is provided on the assembly seat 41; when the mounting seat 31 and the assembly seat 41 are relatively rotated to the second position, the connecting portion 311 and the matching portion 411 are staggered and matched, and after the staggered matching, the connecting portion 311 and the matching portion 411 limit each other along the axial direction of the mop rod 10.

[0146] In the above embodiment, by providing a connecting portion 311 on the mounting seat 31 and providing a matching portion 411 on the assembly seat 41, by controlling the relative rotation of the mounting seat 31 and the assembly seat 41, the connecting portion 311 and the matching portion 411 can be staggered to achieve effective fixation between the collodion head 40 and the pull rod 30. The connection method is simple and efficient, and after staggered matching, the connecting portion 311 and the matching portion 411 limit each other along the axial direction of the mop rod 10, thereby effectively preventing the collodion head 40 from falling off, and effectively solving the problem that the collodion head 40 is easy to fall off when installed in a manner such as a slider slot in the prior art.

[0147] It is necessary to explain that, see Figure 2 and Figure 3As shown, in this embodiment, the staggered matching of the connecting portion 311 and the matching portion 411 can be understood as the installation seat 31 and the assembly seat 41 are alternately arranged, and the connecting portion 311 and the matching portion 411 are staggered and interlaced.

[0148] Further, in some embodiments, one of the connecting portion 311 and the matching portion 411 is a connecting groove 4111, and the other of the connecting portion 311 and the matching portion 411 is a matching block 3111; the connecting groove 4111 is provided with an opening 41110 along the circumference of the mop rod 10, and a necking portion is provided along the axial direction of the mop rod 10; the matching block 3111 is provided with a protruding portion and a shrinking portion along the axial direction of the mop rod 10; the mounting seat 31 and the assembly seat 41 rotate relatively, so that the protruding portion of the matching block 3111 is inserted into the connecting groove 4111 from the opening 41110, and the shrinking portion cooperates with the necking portion, so that the protruding portion and the necking portion limit each other along the axial direction of the mop rod 10.

[0149] In the above embodiment, the connecting portion 311 and the matching portion 411 are in the form of a connecting groove 4111 and a matching block 3111, which has a simple structure. The connecting groove 4111 facilitates the protrusion of the matching block 3111 to enter the connecting groove 4111 when the connecting portion 311 and the matching portion 411 rotate relative to each other through the opening 41110 arranged in the circumferential direction, thereby achieving the connection and fixation between the two. In addition, the connecting groove 4111 and the matching block 3111 adopt the arrangement of the contraction portion and the necking portion, so that the protrusion and the necking portion can limit each other along the axial direction of the mop rod 10, thereby effectively preventing the protrusion from escaping from the connecting groove 4111 along the axial direction of the mop rod 10, and further improving the stability and reliability of the connection between the connecting portion 311 and the matching portion 411.

[0150] Further, in some embodiments, the protruding portion of the matching block 3111 is a matching plate 31111 extending radially along the mop rod 10, and the contracted portion is a matching column 31112 arranged between the matching plate 31111 and the mounting seat 31 or the assembly seat 41; the connecting groove 4111 includes a groove body extending radially along the mop rod 10, and the groove body has an opening 41110 on at least one side of the circumference of the mop rod 10, and a convex plate 41111 extending radially along the mop rod 10 is arranged on one end of the two side walls of the groove body along the axial direction of the mop rod 10 away from the other of the mounting seat 31 or the assembly seat 41, and a contracted portion is formed between the two convex plates 41111.

[0151] In the above embodiment, combined with Figure 6 , Figure 8As shown, by providing two convex plates 41111 on both side walls of the groove body, and having a set interval between the two convex plates 41111, a constricted portion is formed between the two convex plates 41111, so that the protruding portion can be effectively limited in the axial direction of the mop rod 10. By forming the constricted portion through the above two convex plates 41111, the structure is simple and easy to process and form.

[0152] Specifically, the mating plate 31111 is a strip-shaped plate structure, and the extending direction of the mating plate 31111 is parallel to the radial direction of the mop rod 10. The connecting groove 4111 includes a strip-shaped groove body extending in the radial direction of the mop rod 10. The groove body has a "U"-shaped groove wall. Further, convex plates 41111 are respectively provided at the ends of the opposite side walls of the strip-shaped groove body. The two convex plates 41111 extend towards each other, that is, the orientations of the two convex plates 41111 are opposite, and there is a reserved gap space between the ends of the two convex plates 41111, thus forming a constricted portion. A groove body similar to a "convex" shape or a T shape is enclosed between the two convex plates 41111 and the groove body.

[0153] In other alternative embodiments, a convex plate 41111 may also be provided on one of the opposite side walls of the groove body. The convex plate 41111 extends towards the other side wall and has a reserved gap space with the other side wall, thus forming a constricted portion. A groove body similar to an L shape is enclosed between the convex plate 41111 and the groove body.

[0154] Optionally, the contraction portion is fixedly provided at the middle position of the mating plate 31111, and the whole mating block 3111 is in a T shape; or it is fixedly provided at one end of the mating plate 31111, and the whole mating block 3111 is in an L shape.

[0155] In this embodiment, the convex plate 41111 extends in the radial direction of the mop rod 10. In other alternative embodiments, the convex plate 41111 may also extend obliquely, and the end of the convex plate 41111 extends obliquely away from the bottom of the groove body of the groove body.

[0156] Further, in some embodiments, the mating block 3111 is in a T shape or an L shape, and the connecting groove 4111 is correspondingly provided as a T-shaped groove or an L-shaped groove.

[0157] In the above embodiment, the mating block 3111 is a T-shaped block or an L-shaped block, and the connecting groove 4111 is correspondingly provided as a T-shaped groove or an L-shaped groove, so that the mating block 3111 and the connecting groove 4111 can form a constricted portion, a protruding portion and a contraction portion by using their own special shapes, further simplifying the structure and the processing technology. Moreover, when the T-shaped or L-shaped mating block 3111 and the connecting groove 4111 are mutually matched, a good limiting effect can be formed and it is not easy to unhook.

[0158] In some embodiments, after the mounting seat 31 and the assembly seat 41 are interlaced and matched, the connecting portion 311 and the matching portion 411 are snap-fitted.

[0159] In the above embodiment, after the installation seat 31 and the assembly seat 41 are interlaced and matched, the connection portion 311 and the matching portion 411 can be engaged with each other, which can not only form a good limiting effect but also facilitate disassembly and assembly.

[0160] In some embodiments, in combination with 2, Figure 3 , Figure 6 and Figure 7 As shown, when one of the connecting portion 311 and the matching portion 411 is a connecting groove 4111 and the other is a matching block 3111; one of the groove wall of the connecting groove 4111 and the side wall of the matching block 3111 is provided with a limiting protrusion 31113, and the other is provided with a limiting groove 41112; after the mounting seat 31 and the assembly seat 41 are staggered and matched, the limiting protrusion 31113 is snapped into the limiting groove 41112, so that the connecting portion 311 and the matching portion 411 limit each other along the circumference of the mop rod 10.

[0161] In the above embodiment, by providing the limiting protrusion 31113 and the limiting groove 41112 on the groove wall of the connecting groove 4111 and the side wall of the matching block 3111, when the mounting seat 31 and the assembly seat 41 are staggered and matched, the connecting groove 4111 is engaged with the matching block 3111, and the limiting protrusion 31113 can also be engaged with the limiting groove 41112. By the matching of the limiting protrusion 31113 and the limiting groove 41112, the matching block 3111 and the connecting groove 4111 can limit each other in the circumferential direction of the mop rod 10 after matching, so that the matching block 3111 and the connecting groove 4111 can be stably maintained in the current engaging state, thereby effectively avoiding the problem that the matching block 3111 is easily disengaged from the connecting groove 4111 when the rubber sponge head 40 or the mop rod 10 is subjected to a small external force, such as scratching other components or being triggered by the user by mistake, thereby reducing the probability of false triggering and improving the stability and reliability of the rubber sponge head 40 after installation.

[0162] In some embodiments, two T-shaped mating blocks 3111 are provided at both ends of the mounting seat 31, and two T-shaped connecting grooves 4111 are provided at both ends of the assembly seat 41; the outer side walls of the contraction parts of the two T-shaped mating blocks 3111 are provided with limiting protrusions 31113, and the inner side walls of the shrinkage parts of the two T-shaped connecting grooves 4111 are provided with limiting grooves 41112; the mounting seat 31 and the assembly seat 41 rotate relative to each other so that the two T-shaped mating blocks 3111 are respectively staggered with the two T-shaped connecting grooves 4111, so that the limiting protrusions 31113 are snapped into the limiting grooves 41112.

[0163] In the above embodiment, by providing two T-shaped matching blocks 3111 and two T-shaped connecting grooves 4111, the stability and reliability of the matching between the rubber cotton head 40 and the pull rod 30 can be further improved. In addition, by providing a limiting protrusion 31113 on the outer wall of the contraction part of the two T-shaped matching blocks 3111 and correspondingly providing a limiting groove 41112 on the inner wall of the shrinkage part of the two T-shaped connecting grooves 4111, the entire rubber cotton head 40 can be limited from both sides, thereby further reducing the risk of the rubber cotton head 40 accidentally falling off from the pull rod 30 due to accidental triggering.

[0164] In some embodiments, the collodion mop further includes a pin connection; after the mounting seat 31 and the assembly seat 41 are interlaced and matched, the connecting portion 311 and the matching portion 411 are connected through the pin connection.

[0165] In the above embodiment, the pin member is provided to further strengthen the connection between the connecting portion 311 and the matching portion 411 , thereby reducing the risk of the collodion head 40 falling off.

[0166] Optionally, the pin member is inserted between the connecting portion 311 and the matching portion 411 along the axial direction of the mop rod 10, so as to limit the connecting portion 311 and the matching portion 411 in the circumferential direction of the mop rod 10, thereby preventing the collodion head 40 or the mop rod 10 from rotating arbitrarily and causing the connecting portion 311 and the matching portion 411 to be separated.

[0167] Alternatively, in other alternative embodiments, the pin member may also be inserted between the connecting portion 311 and the matching portion 411 along the radial direction of the mop rod 10, so as to not only limit the connecting portion 311 and the matching portion 411 in the circumferential direction of the mop rod 10, but also play a connecting role in the axial direction of the mop rod 10, further strengthen the connection between the connecting portion 311 and the matching portion 411, and achieve better anti-dropping effect and better stability.

[0168] In some embodiments, the mounting seat 31 is provided with a first through hole, and the assembly seat 41 is provided with a second through hole; after the mounting seat 31 and the assembly seat 41 are staggered and matched, the first through hole is connected with the second through hole, and the pin connection part passes through the first through hole and the second through hole to connect the connecting part 311 and the matching part 411.

[0169] In the above embodiment, when the mounting seat 31 and the assembly seat 41 are staggered and matched, the first through hole and the second through hole can be connected to each other correspondingly, so that the pin connection member passes through the first through hole and the second through hole in sequence, and the connection between the connecting portion 311 and the matching portion 411 can be realized, so that the connecting portion 311 and the matching portion 411 can be matched more stably and are not easy to separate. Moreover, the connecting portion 311 and the matching portion 411 are connected by the pin connection member, and the disassembly and assembly are also very convenient and quick.

[0170] Preferably, the central axis directions of the first through hole and the second through hole are parallel to the radial direction of the mop rod 10 .

[0171] Combination Figure 1 , Figures 16 to 19 As shown, in other embodiments of the present invention, a first buckling portion 415 is provided on one of the assembly seat 41 and the mounting seat 31; when the mounting seat 31 and the assembly seat 41 are relatively rotated to the second position, the first buckling portion 415 buckles with the other of the assembly seat 41 and the mounting seat 31, and after buckling, the first buckling portion 415 and the other of the assembly seat 41 and the mounting seat 31 limit each other along the axial direction of the mop rod 10.

[0172] In the above embodiment, by providing the first snap-fitting portion 415 on one of the assembly seat 41 and the mounting seat 31, when the mounting seat 31 and the assembly seat 41 are relatively rotated to the second position, the first snap-fitting portion 415 snaps with the other of the assembly seat 41 and the mounting seat 31, so that the assembly seat 41 and the mounting seat 31 can form a stable limit in the axial direction of the mop rod 10, effectively preventing the collodion head 40 from falling off.

[0173] In some embodiments, the first buckling portion 415 is an anti-drop buckle provided on the assembly seat 41 and extending toward the mounting seat 31 ; when the mounting seat 31 and the assembly seat 41 rotate relative to each other to the second position, the anti-drop buckle is snap-fitted with the top of the mounting seat 31 .

[0174] In the above embodiment, the first buckle portion 415 adopts an anti-drop buckle structure, and the anti-drop buckle can be directly snapped and snapped onto the top wall of the mounting seat 31, which not only forms a better anti-drop effect, but also eliminates the need to add an additional structure on the mounting seat 31 to cooperate with the first buckle portion 415, thereby achieving the purpose of simplifying the structure.

[0175] Further, in some embodiments, a side wall of the other of the assembly seat 41 and the mounting seat 31 is provided with a second snap-fitting portion 315; when the mounting seat 31 and the assembly seat 41 are relatively rotated to the second position, the first snap-fitting portion 415 and the second snap-fitting portion 315 are snap-fitted, and after the snap-fitting, the first snap-fitting portion 415 and the second snap-fitting portion 315 limit each other along the axial direction of the mop rod 10.

[0176] In the above embodiment, by providing the second buckling portion 315 on the other of the assembly seat 41 and the mounting seat 31, the second buckling portion 315 is buckled with the first buckling portion 415 to limit the assembly seat 41 and the mounting seat 31 in the axial direction of the mop rod 10, thereby achieving a better anti-falling effect.

[0177] Preferably, in this embodiment, the first buckling portion 415 is provided on the assembly seat 41, and the first buckling portion 415 can be directly buckled on the top wall of the mounting seat 31. Further, the top wall can also be provided with a groove or a recessed portion to prevent the first buckling portion 415 from being disengaged, and the groove or the recessed portion can form a second buckling portion 315; or the second buckling portion 315 is provided on the side wall of the mounting seat 31, and the first buckling portion 415 is buckled on the second buckling portion 315 on the side wall of the mounting seat 31.

[0178] Alternatively, the first buckling portion 415 is provided on the mounting seat 31, and the first buckling portion 415 can be directly buckled on the bottom of the assembly seat 41. Further, the bottom can also be provided with a groove or a recessed portion to prevent the first buckling portion 415 from being disengaged, and the groove or the recessed portion can form the second buckling portion 315; or the second buckling portion 315 is provided on the side wall of the assembly seat 41, and the first buckling portion 415 is buckled on the second buckling portion 315 on the side wall of the assembly seat 41.

[0179] In some embodiments, an anti-drop buckle is provided on the top of the side wall of the assembly seat 41. After the mounting seat 31 and the assembly seat 41 rotate relative to each other, the anti-drop buckle can be buckled on the top of the mounting seat 31 to achieve axial limitation of the two along the mop rod 10.

[0180] Specifically, the first snap-fitting portion 415 is an anti-dropping buckle arranged on the assembly seat 41 and extending in the direction close to the mounting seat 31, and the second snap-fitting portion 315 is a snap-fitting groove arranged on the side wall of the mounting seat 31; when the mounting seat 31 and the assembly seat 41 are relatively rotated to the second position, the anti-dropping buckle is inserted into the snap-fitting groove and snap-fitted with the snap-fitting groove.

[0181] In the above embodiment, the first buckle portion 415 adopts an anti-drop buckle, and the second buckle portion 315 adopts a buckle groove structure, which not only can form a good anti-drop effect, but also makes disassembly and assembly more convenient and quick, and the structure is also relatively simple and easy to process and shape.

[0182] Specifically, the anti-drop buckle can be fixedly set on the top wall of the assembly seat 41, or it can also be fixedly set on the top side wall of the assembly seat 41. A snap-fit ​​groove is provided on the top of the side wall of the mounting seat 31. When the mounting seat 31 and the assembly seat 41 are relatively rotated to the second position, the anti-drop buckle can be buckled in the snap-fit ​​groove. The mounting seat 31 and the assembly seat 41 are both limited along the axial direction of the mop rod 10, thereby realizing the axial limitation of the cotton head 40 and the pull rod 30.

[0183] Preferably, the anti-trip buckle is fixedly arranged on the top wall of the assembly seat 41, and there are two anti-trip buckles, which are distributed at both ends of the assembly seat 41 and located on opposite sides. Two opposite side walls of the mounting seat 31 are provided with two snap-fitting grooves corresponding to the two anti-trip buckles. When the mounting seat 31 and the assembly seat 41 are relatively rotated to the second position, the two anti-trip buckles are respectively snap-fitted and snapped on both sides of the mounting seat 31. By adopting two groups of anti-trip buckles, and arranging the two groups of anti-trip buckles at intervals at both ends of the assembly seat 41 and on both sides of the assembly seat 41, compared with the solution of arranging the anti-trip buckles on one side, the stability of the overall structure after the assembly seat 41 and the mounting seat 31 are snap-fitted can be further improved, and the problem of partial or unilateral tilting and tripping due to unbalanced force will not occur.

[0184] Furthermore, in the present embodiment, the anti-drop buckle is integrally formed with the assembly seat 41 , the anti-drop buckle is an L-shaped buckle, and the buckling groove is an L-shaped stepped groove provided on the top wall of the mounting seat 31 .

[0185] In some embodiments, the collodion mop further includes a rotation positioning structure, which is disposed between the assembly seat 41 and the mounting seat 31 and is used to position the assembly seat 41 and the mounting seat 31 axially on the mop rod 10 when the mounting seat 31 and the assembly seat 41 rotate relative to each other.

[0186] In the above embodiment, by providing a rotational positioning structure, when the mounting seat 31 and the assembly seat 41 rotate relative to each other, the assembly seat 41 and the mounting seat 31 can be positioned axially on the mop rod 10, so that the assembly seat 41 and the mounting seat 31 can rotate with the rotational positioning structure as the rotation axis, so that during the rotation of the assembly seat 41 and the mounting seat 31, the connecting portion 311 and the matching portion 411 can be quickly and accurately docked, thereby improving the assembly efficiency.

[0187] In this embodiment, the rotation axis of the mounting seat 31 and the assembly seat 41 is parallel to or coincides with the central axis of the mop rod 10. Preferably, the rotation axis of the mounting seat 31 and the assembly seat 41 is coincident with the central axis of the mop rod 10.

[0188] In some specific embodiments, the rotational positioning structure includes a positioning portion and a positioning matching portion, the positioning portion is arranged on one of the assembly seat 41 and the mounting seat 31; the positioning matching portion corresponds to the positioning portion arranged on the other of the assembly seat 41 and the mounting seat 31, the positioning portion and the positioning matching portion are plugged and positioned together, and can rotate relative to each other.

[0189] In the above embodiment, the positioning portion and the positioning matching portion are plugged and positioned, and the two can rotate relative to each other, so that the assembly seat 41 and the mounting seat 31 can be positioned along the axial direction of the mop rod 10, and the disassembly and assembly of the collodion head 40 through the relative rotation of the assembly seat 41 and the mounting seat 31 will not be affected. In addition, the positioning portion and the positioning matching portion are positioned by plugging, which is efficient and convenient for disassembly and assembly.

[0190] In some embodiments, in combination Figure 3 , Figure 6 , Figure 7 , Fig.14 , Fig.15 As shown, the positioning portion includes a positioning column 312, which extends along the axial direction of the mop rod 10 and is fixedly arranged at the center of the mounting seat 31; the positioning matching portion includes a positioning hole 412 which is arranged at the center of the assembly seat 41 and extends along the axial direction of the mop rod 10, and the positioning column 312 is suitable for being inserted into the positioning hole 412 and can rotate in the positioning hole 412. At this time, the rotation axis of the mounting seat 31 and the assembly seat 41 is the central axis of the positioning column 312, and the central axis can coincide with the central axis of the mop rod 10.

[0191] In the above embodiment, the positioning portion and the positioning matching portion are in the form of positioning posts 312 and positioning holes 412, which have a simple structure and are easy to process and shape.

[0192] In some embodiments, one of the mounting seat 31 and the assembly seat 41 is provided with a stop positioning structure, which is used to limit the mounting seat 31 and the assembly seat 41 when the mounting seat 31 and the assembly seat 41 rotate relative to each other to the second position, so as to restrict the mounting seat 31 and the assembly seat 41 from continuing to rotate in the same direction.

[0193] In the above embodiment, the stop positioning structure is set up so that the mounting seat 31 and the assembly seat 41 can be relatively rotated to the second position, so that after the connecting portion 311 and the matching portion 411 are staggered and matched, the mounting seat 31 and the assembly seat 41 are limited, thereby effectively avoiding the phenomenon that the matching block 3111 is disengaged from the other side of the connecting groove 4111 due to excessive rotation.

[0194] In some embodiments, in combination Figure 8 , Fig. 9 As shown, the collodion mop includes a positioning column 312 and a positioning hole 412 for positioning the assembly seat 41 and the mounting seat 31 along the axial direction of the mop rod 10 when the mounting seat 31 and the assembly seat 41 rotate relative to each other; the stop positioning structure includes a stop portion 313 and a positioning groove 413 that cooperate with each other, and the stop portion 313 is provided on one of the outer peripheral wall of the positioning column 312 or the inner peripheral wall of the positioning hole 412, and the positioning groove 413 is provided on the other; when the mounting seat 31 and the assembly seat 41 rotate relative to each other to the second position, the stop portion 313 rotates into the positioning groove 413.

[0195] In the above embodiment, by means of the stopper 313 and the positioning groove 413 provided on the outer peripheral wall of the positioning column 312 and the inner peripheral wall of the positioning hole 412, when the mounting seat 31 and the assembly seat 41 rotate relative to each other to the second position, the stopper 313 also rotates into the positioning groove 413 to form a positioning, thereby limiting the mounting seat 31 and the assembly seat 41 from continuing to rotate. At this time, the mounting seat 31 or the assembly seat 41 can be stopped from rotating further, thereby avoiding the phenomenon that the mating portion 411 is disengaged from the other side of the connecting portion 311 due to excessive rotation.

[0196] Specifically, in this embodiment, a stopper 313 is provided on the outer peripheral wall of the positioning column 312, and a positioning groove 413 is provided on the inner peripheral wall of the positioning hole 412. There are two stoppers 313, which are symmetrically arranged on both sides of the positioning column 312, and two positioning grooves 413 are correspondingly provided on the inner peripheral wall of the positioning hole 412, and the two positioning grooves 413 are symmetrically arranged on opposite sides of the positioning hole 412. By providing two sets of stoppers 313 and positioning grooves 413, the positioning effect can be further improved.

[0197] In some embodiments, Figures 10 to 12 As shown, the stop and positioning structure also includes an outer baffle 314 arranged at both ends of the mounting seat 31; one of the inner side of the outer baffle 314 and the outer side of the assembly seat 41 is provided with a stop portion 313, and the other is provided with a positioning groove 413; when the mounting seat 31 and the assembly seat 41 are relatively rotated to the second position, the outer baffles 314 at both ends of the mounting seat 31 are respectively abutted against the two ends of the assembly seat 41, and the stop portion 313 is rotated into the positioning groove 413.

[0198] In the above embodiment, by setting the peripheral baffles 314 at both ends of the mounting seat 31, after the collodion head 40 is rotated and installed in place, the peripheral baffles 314 are located outside the assembly seat 41 of the collodion head 40, and the peripheral baffles 314 and the stopper 313 and the positioning groove 413 on the assembly seat 41 can cooperate with each other to form a positioning, limiting the mounting seat 31 and the assembly seat 41 from continuing to rotate. At this time, the mounting seat 31 or the assembly seat 41 can be stopped from continuing to rotate, thereby avoiding the phenomenon that the matching portion 411 on the assembly seat 41 is disengaged from the connecting portion 311 on the mounting seat 31 due to excessive rotation. In addition, the peripheral baffles 314 can also protect the mounting seat 31 and the assembly seat 41.

[0199] Specifically, the outer baffle 314 is fixedly arranged at both ends of the mounting seat 31, and a set spacing space is provided between the outer baffle 314 and the outer side wall of the mounting seat 31 for the assembly seat 41 to extend into. The outer baffle 314 is a straight plate-shaped structure, the stopper 313 is fixedly arranged on the inner side wall of the outer baffle 314, and the outer side walls at both ends of the mounting seat 31 are respectively provided with positioning grooves 413.

[0200] In some embodiments, the stopper 313 is an arc-shaped protrusion, and the positioning groove 413 is an arc-shaped groove.

[0201] In the above embodiment, the stopper 313 and the positioning groove 413 adopt an arc-shaped design, which can not only play a certain positioning and limiting role, but also achieve the purpose of preventing jamming, ensuring that when the user wants to disassemble and assemble the cotton wool head 40, the stopper 313 can be disengaged from the positioning groove 413 without applying too much force, so that the mounting seat 31 and the assembly seat 41 can rotate freely, so that the user can disassemble and assemble the cotton wool head 40 more easily and with less effort.

[0202] Specifically, the stopper 313 is a semi-cylindrical structure, the positioning groove 413 is a semi-cylindrical groove, and the extending direction of the stopper 313 is parallel to the axial direction of the mop rod 10 .

[0203] In some embodiments, Figures 13 to 15 As shown, when one of the connecting portion 311 and the matching portion 411 is a connecting groove 4111, and the other of the connecting portion 311 and the matching portion 411 is a matching block 3111; the stop positioning structure includes a limiting member 414, and the connecting groove 4111 is provided with an opening 41110 on one side along the circumference of the mop rod 10, and a limiting member 414 is provided on the other side. When the mounting seat 31 and the assembly seat 41 are relatively rotated until the connecting portion 311 and the matching portion 411 are staggered and matched, the limiting member 414 abuts against the side wall of the matching block 3111.

[0204] In the above embodiment, an opening 41110 is provided on one side of the connecting groove 4111 and a limiting member 414 is fixedly provided on the other side. When the mounting seat 31 and the assembly seat 41 rotate relative to each other, the mating block 3111 can enter the interior of the connecting groove 4111 from the opening side of the connecting groove 4111, and when the mounting seat 31 and the assembly seat 41 continue to rotate, the limiting member 414 can limit the maximum rotational displacement of the mating block 3111, that is, the mating block 3111 can be rotated to a position abutting against the limiting member 414 at most, thereby effectively avoiding the phenomenon that the mating block 3111 falls out of the other side of the connecting groove 4111 due to excessive rotation.

[0205] Specifically, the connecting groove 4111 has an opening side and a blocking side that are relatively arranged in the circumferential direction of the mop rod 10. The opening side allows the matching block 3111 to enter the connecting groove 4111, and the limiting member 414 is fixedly arranged on the blocking side to limit the maximum rotational displacement of the matching block 3111, thereby effectively preventing the matching block 3111 from excessively rotating and falling out of the connecting groove 4111.

[0206] In some embodiments, the stopper 414 is a stopper plate disposed on the other side of the connecting groove 4111 along the circumference of the mop rod 10 , so that the other side of the connecting groove 4111 along the circumference of the mop rod 10 is a blind end.

[0207] In the above embodiment, the limiting member 414 adopts a limiting plate design that blocks the other side of the connecting groove 4111, and has a simple structure. The limiting plate can completely close the other side of the connecting groove 4111, so the structure is more stable and the limiting effect is better.

[0208] In some more specific implementations, a connecting groove 4111 is provided on the assembly seat 41 , a matching block 3111 is provided on the mounting seat 31 , and the limiting member 414 is integrally formed with the assembly seat 41 .

[0209] Furthermore, two connection grooves 4111 are arranged at intervals on the assembly seat 41, and the two connection grooves 4111 are symmetrically distributed on both sides of the rotation positioning structure. Two matching blocks 3111 are correspondingly arranged on the mounting seat 31, and the two matching blocks 3111 are also symmetrical about the rotation positioning structure. There are two limit members 414, and the two limit members 414 are arranged on different sides of the two connection grooves 4111. The openings 41110 of the two connection grooves 4111 are located on both sides of the assembly seat 41. Such a design facilitates that when the assembly seat 41 and the mounting seat 31 rotate relative to each other, the two matching blocks 3111 located on both sides of the rotation positioning structure can be screwed into the corresponding connection grooves 4111 from both sides.

[0210] In some embodiments, the collodion head 40 has a fixed state and a disassembly state: when the mounting seat 31 and the assembly seat 41 rotate relative to each other to the second position, the collodion head 40 is in a fixed state; when the mounting seat 31 and the assembly seat 41 rotate relative to each other to the point where the mounting seat 31 and the assembly seat 41 are misaligned, the collodion head 40 is in a disassembly state.

[0211] In the above embodiment, by rotating the collodion head 40 or the pull rod 30, the mounting seat 31 and the assembly seat 41 can be located in a first position where they do not completely overlap and can be detached, or in a second position where they are not completely misaligned and limited to each other along the axial direction of the mop rod 10, that is, the collodion head 40 can be disassembled or fixed, making the disassembly and assembly of the collodion head 40 more convenient, quick and efficient.

[0212] In some embodiments, the mounting seat 31 and the assembly seat 41 are both strip structures; when the collodion head 40 is in a fixed state, the mounting seat 31 and the assembly seat 41 are roughly aligned along the radial direction of the mop rod 10; when the collodion head 40 is in a disassembled state, the mounting seat 31 and the assembly seat 41 are misaligned.

[0213] In the above embodiment, the user can rotate the mop rod 10 or the cotton wool head 40 to align or stagger the mounting seat 31 and the assembly seat 41, thereby controlling the cotton wool head 40 to switch between a fixed state and a disassembly state, thereby making the disassembly and assembly of the cotton wool head 40 more convenient and quick, and further improving the assembly efficiency of the cotton wool head 40.

[0214] Specifically, the mounting seat 31 and the assembly seat 41 are both strip-shaped block structures. When the collodion head 40 is in a fixed state, the mounting seat 31 and the assembly seat 41 are radially aligned along the mop rod 10, and the two are parallel to each other; when the collodion head 40 is in a disassembly state, the mounting seat 31 and the assembly seat 41 can be rotated to a state perpendicular to each other, so that the mounting seat 31 and the assembly seat 41 can be separated, and then the collodion head 40 can be disassembled.

[0215] Further, in some embodiments, when the mounting seat 31 is provided with a connecting portion 311 and the assembly seat 41 is provided with a matching portion 411; when the mounting seat 31 and the assembly seat 41 are relatively rotated until the connecting portion 311 and the matching portion 411 are staggered and matched, the mounting seat 31 and the assembly seat 41 are located at a second position where they are mutually limited along the axial direction of the mop rod 10, and the collodion head 40 is in a fixed state, at which time the mounting seat 31 and the assembly seat 41 can both extend along the length direction of the collodion head 40. When the mounting seat 31 and the assembly seat 41 are relatively rotated until the connecting portion 311 and the matching portion 411 are disengaged, the mounting seat 31 and the assembly seat 41 are located at a first position where they can be disengaged along the mop rod 10, and the collodion head 40 is in a disassembly state, at which time the mounting seat 31 and the assembly seat 41 are in a staggered intersecting state.

[0216] In some embodiments, at least two connecting portions 311 may be provided on the mounting seat 31 along its length direction, and at least two matching portions 411 may be correspondingly provided on the assembly seat 41 .

[0217] In the above embodiment, the mounting seat 31 and the assembly seat 41 are connected and fixed by limiting the cooperation of at least two connecting parts 311 and at least two matching parts 411, which can further improve the stability and reliability of the structure of the collodion head 40 after fixation and reduce the risk of the collodion head 40 falling off.

[0218] In some embodiments, the connecting part 311 includes a first connecting part and a second connecting part, the second connecting part has two, and the two second connecting parts are symmetrically distributed on both sides of the first connecting part; one of the first connecting part and the second connecting part is a matching block 3111, and the other is a connecting groove 4111; the matching part 411 includes a first matching part and a second matching part which are respectively arranged corresponding to the first connecting part and the second connecting part.

[0219] In the above embodiment, the three connecting parts 311 are arranged on the mounting seat 31, and the three connecting parts 311 adopt a mixed structure of the matching block 3111 and the connecting groove 4111. Compared with the mounting seat 31 adopting a single matching block 3111 or a connecting groove 4111, a clamping point can be formed on both the mounting seat 31 and the assembly seat 41, and the clamping points are dispersed on the mounting seat 31 and the assembly seat 41, thereby further improving the fixing effect, thereby effectively avoiding the problem that the clamping points are concentrated on the mounting seat 31 or the assembly seat 41, affecting the stability of the cotton wool head 40 after assembly.

[0220] In other alternative embodiments, the mounting seat 31 may be provided with only two connection portions 311, one of which is a matching block 3111, and the other is a connection groove 4111. This embodiment does not limit the number of connection portions 311, as long as the connection portions 311 on the mounting seat 31 are in the form of a mixture of matching blocks 3111 and connection grooves 4111.

[0221] In some embodiments, the first connecting portion is a first connecting groove arranged in the middle position of the mounting seat 31, and the second connecting portion is two second matching blocks symmetrically arranged on both sides of the first connecting portion; the first matching portion includes a first matching block corresponding to the first connecting portion arranged in the middle position of the assembly seat 41, and the second matching portion includes two second connecting grooves symmetrically arranged on both sides of the first matching portion corresponding to the second connecting portion.

[0222] In the above embodiment, the positioning hole 412 can be opened at the center of the first matching block, and the positioning column 312 is fixedly arranged at the center of the first connecting groove. The first matching part includes a first matching plate and a first matching column. The first matching plate is a strip plate structure extending along the radial direction of the mop rod 10. The length of the first matching plate matches the length of the first connecting groove, and the width of the first matching plate is smaller than the length of the first connecting groove, so that when assembling or disassembling, the first matching plate can be obliquely or vertically entered and exited from the first connecting groove, which is convenient for assembly and disassembly.

[0223] Specifically, when assembling the cotton head 40, the mounting seat 31 and the assembly seat 41 are in a cross state, and the positioning column 312 and the positioning hole 412 are aligned, and then the assembly seat 41 or the mounting seat 31 is rotated so that the assembly seat 41 or the mounting seat 31 is aligned, and the first mating plate can be engaged into the first connecting groove, and the two second mating blocks located on both sides of the first connecting groove can also be screwed into the second connecting groove from the opening 41110 on the side of the second connecting groove, so that the first connecting groove in the middle and the first mating block, and the two second mating blocks located on both sides and the two second connecting grooves can be engaged and limited respectively.

[0224] In some embodiments, the bottom of the second connecting groove is recessed downward to form a recessed portion 41113, and a screw hole is opened in the recessed portion 41113; the screw passes through the screw hole and is connected to the mounting bracket 42 of the cotton wool head 40, and the screw cap of the screw is placed in the recessed portion 41113.

[0225] In the above embodiment, the recessed portion 41113 is provided to accommodate the screw nut, which can effectively avoid interference between the screw nut and the matching block 3111 and affect the user's rotation and disassembly of the cotton pad head 40.

[0226] Specifically, the collodion head 40 includes a mounting bracket 42 and a collodion head body 43 detachably mounted on the mounting bracket 42, and the assembly seat 41 is fixed to the mounting bracket 42 by two screws. The mounting bracket 42 and the assembly seat 41 can both be bar structures.

[0227] When installing the collodion mop provided in this embodiment, firstly, the collodion head 40 and the connecting seat are in a vertical state or an inclined cross state, and then the collodion head 40 and the mounting seat 31 are brought close to each other until the positioning column 312 and the positioning hole 412 are inserted and positioned, and then the collodion head 40 is rotated until the matching block 3111 is engaged with the connecting groove 4111, and then the collodion head 40 is installed. When disassembling, that is, the collodion head 40 is rotated in the opposite direction, so that the matching block 3111 and the connecting groove 4111 are staggered in the circumferential direction, and then the collodion head 40 and the pull rod 30 are moved away from each other in the axial direction of the mop rod 10, and then the collodion head 40 is disassembled.

[0228] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
