Description

Technical Field

[0001] The utility model relates to an open - type folding and shrinking foam cotton mop head, where the foam cotton can be colloid cotton, sponge, comfort cotton or the like. The utility model also relates to a mop. Background Art

[0002] At present, the water - squeezing method of the foam cotton mops on the market is to squeeze along the thickness direction of the foam cotton. When squeezing water, the deformation amount is small, the water - squeezing effect is not good, the water - squeezing stroke is long, and the operation is inconvenient. There is currently a foam cotton wiping material on the market with a density lower than that of colloid cotton and a different formula (such as comfort cotton on the market). This foam cotton wiping material has the following advantages compared with colloid cotton: comfort cotton does not become hard and is environmentally friendly and biodegradable. In addition, its water absorption is not inferior to that of colloid cotton. However, the adhesive force between this comfort cotton and the plastic connecting plate is poor. During the self - water - squeezing process, a large pulling force will be generated between the foam cotton and the plastic connecting plate, and the foam cotton is easily detached from the plastic connecting plate, resulting in damage and inability to be used normally. The glue used for bonding has a pungent smell, is volatile, harmful to the human body, and not environmentally friendly.

[0003] In view of the foregoing situation, the applicant applied for a patent for a foam cotton mop with a completely new structure. For example, the Chinese utility model patent "Foam Cotton Mop Head and Mop" with the patent number ZL202223240604.2 (publication number CN219557184U) discloses such a foam cotton mop head, which includes a foam cotton wiping material, a bracket for connecting with a mop rod. Swingable swing members are hinged on the left and right sides of the bracket. The foam cotton wiping material is constrained on the swing members and can contract or extend along its length direction. When the swing members on both sides swing to the vertical direction, the lower end of the foam cotton wiping material contracts from bottom to top, or the upper end of the foam cotton wiping material contracts from top to bottom to achieve water squeezing. The swing member is in a shaft shape, and the foam cotton wiping material surrounds and covers the outer periphery of the swing member. The middle part of the foam cotton wiping material has a notch for placing the bracket therein. Insertion holes for inserting the swing members are provided in the foam cotton wiping material on both sides of the notch. When the swing members swing downward relative to the bracket to the vertical direction, the insertion holes of the foam cotton wiping material folded along the middle are upward, and the two swing members can be vertically inserted into the insertion holes, and a plug for blocking the foam cotton wiping material is connected to the outer end of the swing member.

[0004] To form the foregoing foam cotton structure, it is necessary to use a core - pulling method in the mold, and the mold is divided at the middle part of the foam cotton. It is necessary to set exhaust holes at the top of the mold (above the top surface of the foam cotton), so that bubbles are easily accumulated on the top surface of this structure of foam cotton, affecting the product quality.

[0005] Therefore, the foregoing foam cotton mop head can be further improved. Summary of the Utility Model

[0006] The first technical problem to be solved by the present utility model is to provide a foam cotton mop head with a more reasonable structure that can change the traditional water squeezing method of the foam cotton mop, which has less foam cotton consumables, is easier to manufacture, can simplify the corresponding mold structure, and further reduce costs in view of the above-mentioned current technical situation.

[0007] The technical solution adopted by the present utility model to solve the above first technical problem is as follows: an open-type folding and shrinking foam cotton mop head, including a foam cotton wiping object and a bracket for connecting with a mop rod. Swingable swing parts are hinged on the left and right sides of the bracket. The foam cotton wiping object is constrained on the swing parts and can shrink or stretch along its length direction. When the swing parts on both sides swing to the vertical direction, water is squeezed out by the shrinkage of the foam cotton wiping object. It is characterized in that: in the state where the foam cotton wiping object is constrained on the swing parts, the second top surface of the foam cotton wiping object is exposed on the first top surface or side surface of the swing parts.

[0008] Compared with the prior art, the advantages of this foam cotton mop head are as follows: in the state where the foam cotton wiping object is constrained on the swing parts, the second top surface of the foam cotton wiping object is exposed on the first top surface of the swing parts, so that the foam cotton wiping object does not need to be provided with perforations, that is, the mold does not need to be designed with a core-pulling mechanism, which simplifies the structure of the mold, and the consumables of the overall foam cotton will also be reduced; furthermore, due to the structural characteristics of this foam cotton, the mold parting surface can be designed above the top of the foam cotton. During the manufacturing process, hot air can be directly discharged from the parting surface, and the exhaust is smoother. There is no need to additionally set exhaust holes at the top. This structural characteristic of the foam cotton avoids the accumulation of air bubbles at the top position of the foam cotton during the manufacturing process and improves the quality of the foam cotton. The foam cotton wiping object of this mop head is first folded in half and then shrinks or stretches along its length direction to squeeze water. The foam cotton wiping object can be squeezed in a large amount, and the cross-section of the foam cotton wiping object is small, so the squeezing force required per unit length is small. After folding in half, the length becomes shorter, and the water squeezing effect is better and the efficiency is higher with the same extrusion amount.

[0009] For further improvement, the above-mentioned foam cotton wiping object has a bottom, and the front and rear sides of the bottom have upwardly extending side walls. The bottom and the two side walls enclose an installation groove for placing the swing parts therein. The overall cross-section of the foam cotton is U-shaped, making the foam cotton in a semi-surrounding open-type structure, so that the foam cotton wiping object is semi-wrapped on the swing parts, which is more firmly combined with the swing parts, and the side walls of the swing parts can also play a cleaning role.

[0010] To facilitate the constraint of the foam cotton wiping object on the mounting plate, a plurality of mounting plates are fixed on the above-mentioned foam cotton wiping object. The mounting plates are installed on the swing parts placed in the installation groove through a guide rail structure, and the mounting plates can slide axially along the swing parts. The mounting plates can be made of hard plastic, which is beneficial to connect with the swing parts through the guide rail structure.

[0011] For further improvement, the above mounting plate is formed in the foam cleaning wipe by means of an insert. A part of the mounting plate is exposed from the mounting groove to form a connecting part, and the connecting part of the mounting plate is connected to the swing member placed in the mounting groove. Forming the mounting plate in the foam cleaning wipe by means of an insert enables the mounting plate to be firmly fixed on the foam cleaning wipe without using glue, which is more environmentally friendly; the mounting plate is embedded in the foam cleaning wipe to form the framework of the foam cleaning wipe, strengthening the strength of the foam cleaning wipe. A part of the mounting plate is exposed from the mounting groove to form a connecting part connected to the mounting plate, and the structural design is very reasonable.

[0012] As a preferred way of the guide rail structure, a guide groove is provided on the above swing member, and the connecting part is snapped into the guide groove to form a sliding fit; of course, the guide rail structure can also adopt the following way, a guide groove is provided on the connecting part, and a guide block slidably matched with the guide groove is provided on the swing member.

[0013] Preferably, the cross-section of the above mounting groove is arc-shaped, and the bottom surface of the swing member is arc-shaped and matches the bottom surface of the mounting groove. The contact surface between the mounting groove and the swing member is arc-shaped, which can make the contact surface between the two smoother and their combination more stable.

[0014] If the end of the foam cleaning wipe is not fixed, the inward contraction during mopping will affect the comfort of mopping. To avoid this situation, for further improvement, a locking button for locking the outermost mounting plate is provided on the above swing member. In the unfolded state, the end of the foam cleaning wipe is fixed relative to the swing member, and when applying force to mop along the length direction of the foam cleaning wipe, the two ends of the foam cleaning wipe will not contract inward under the action of friction.

[0015] The second technical problem to be solved by the present utility model is a foam cleaning mop that changes the traditional water squeezing method of the foam cleaning mop, and the water squeezing effect of the mop head is better and the operation is convenient and labor-saving.

[0016] The technical solution adopted by the present utility model to solve the above second technical problem is: a mop, including a first rod, a second rod and a water squeezing frame, characterized in that: it further includes the above foam cleaning mop head, the bracket is connected to the lower end of the first rod, the water squeezing frame is connected to the lower end of the second rod, the swing member has a tendency to be kept horizontally unfolded by the action of a first elastic member, the first rod and the second rod are sleeved with each other and can move relative to each other, the downward movement of the water squeezing frame relative to the bracket can push the swing members on both sides to swing downward relative to the bracket and fold, and the further downward movement of the water squeezing frame can drive the upper end of the folded foam cleaning wipe to contract from top to bottom to achieve water squeezing.

[0017] As a specific setting mode of the water squeezing frame, the above-mentioned first rod is sleeved outside the second rod, and a locking member is arranged inside the bracket. The locking member is kept in a tendency of locking the swinging member in the horizontal position by the action of the second elastic member, and the downward movement of the water squeezing frame can drive the locking member to move in the unlocking direction. To ensure the orderly movement of each component and no interference with each other, the downward movement of the water squeezing frame first triggers the locking member to move to the unlocking position, and the further downward movement of the water squeezing frame then pushes the swinging member to swing downward relative to the bracket and fold in half. When mopping the floor, the locking member always locks the swinging member in the horizontal position, and it will not swing passively due to the friction between the wiping material and the ground. Only when the second rod moves downward relative to the first rod, that is, drives the water squeezing frame to move downward to make the locking member move in the unlocking direction, and the further downward movement drives the swinging member to fold in half.

[0018] The aforementioned water squeezing frame is driven by the second rod (inner rod), which miniaturizes the water squeezing frame and basically arranges it inside the bracket, making the overall structure more compact and reducing the packaging volume. Of course, the water squeezing frame can also be driven by an outer rod, that is, the second rod is sleeved outside the first rod, and the water squeezing frame is arranged outside the bracket, similar to a sleeve-type water squeezing frame.

[0019] As a preferred setting mode of the locking member, the middle part of the above-mentioned locking member is hinged inside the bracket. The second elastic member acts on the locking member to make the lower end of the locking member have a tendency to swing outward. The inner end of the swinging member has a blocking portion. The lower end of the locking member swings outward and abuts above the blocking portion to prevent the swinging member from swinging downward relative to the bracket. The downward movement of the water squeezing frame can push the upper end of the locking member and make the lower end of the locking member swing inward to disengage from the blocking portion. The second elastic member can be a spring or a torsion spring. In this structure, the locking member realizes the locking and unlocking of the swinging member through its own swing, involving fewer components, simple structure and convenient assembly.

[0020] Of course, other existing methods can also be adopted for the locking method.

[0021] Compared with the prior art, the advantages of this foamed cotton mop are as follows: through the relative axial movement of the first rod and the second rod, the downward movement of the water squeezing frame relative to the bracket can push the swinging members on both sides to swing downward relative to the bracket and fold in half. The foamed cotton wiping material is folded in half passively to squeeze out a part of the water first, and then the foamed cotton is squeezed along its length direction (vertically). After folding in half, the length becomes shorter, and the water squeezing effect is better with the same extrusion amount, that is, to achieve the same squeezing dry effect, greatly shortening the water squeezing stroke, higher water squeezing efficiency and more labor-saving operation.

[0033] The present utility model will be further described in detail below in conjunction with the embodiments with reference to the drawings.

[0034] As Figures 1 to 11 shown, it is a preferred embodiment of a mop with an open-type folded and shrinkable foamed cotton mop head.

[0035] A mop includes a first rod 4a, a second rod 4b and a water squeezing frame 7, and further includes an open-type folded and shrinkable foamed cotton mop head. The mop head specifically includes a foamed cotton wiper 1 and a bracket 3 for connecting with the first rod 4a. Swingable swinging members 2 are hinged on the left and right sides of the bracket 3. The foamed cotton wiper 1 is constrained on the swinging members 2 and can contract or extend along its length direction. When the swinging members 2 on both sides swing to the vertical direction, water squeezing is achieved through the contraction of the foamed cotton wiper 1. In the state where the foamed cotton wiper 1 is constrained on the swinging members 2, a second top surface 1a of the foamed cotton wiper 1 is exposed on a first top surface 2a of the swinging members 2.

[0036] The foam cotton wiper 1 has a bottom 11. On the front and rear sides of the bottom 11, there are side walls 12 extending upward. The bottom 11 and the two side walls 12 enclose an installation groove 1b for placing the swing member 2 therein. The cross-section of the installation groove 1b is arc-shaped, and the bottom surface of the swing member 2 is arc-shaped and matches the bottom surface of the installation groove 1b.

[0037] Multiple mounting plates 5 are fixed on the foam cotton wiper 1. The mounting plates 5 are in the shape of thin plates. The mounting plates 5 are installed on the swing member 2 placed in the installation groove 1b through a guide rail structure, and the mounting plates 5 can slide axially along the swing member 2. The mounting plates 5 are formed in the foam cotton wiper 1 by an insert molding method. A part of the mounting plate 5 is exposed outside the installation groove 1b to form a connecting portion 5a, and the connecting portion 5a of the mounting plate 5 is connected to the swing member 2 placed in the installation groove 1b.

[0038] The swing member 2 is provided with a guide groove 21. The connecting portion 5a is snapped into the guide groove 21 to form a sliding fit; the guide groove can be provided on the side of the swing member, or on the bottom of the swing member. It can also be that the guide groove is provided on the mounting plate, and guide ribs are provided on the side of the swing member, as Figure 11 shown.

[0039] Or, the connecting portion is provided with a guide groove, and the swing member is provided with a guide block that is slidably matched with the guide groove, as shown in the figure.

[0040] Each swing member 2 is provided with a lock button 6 for locking the outermost mounting plate on the swing member 2.

[0041] The bracket 3 is connected to the lower end of the first rod 4a, and the water squeezing frame 7 is connected to the lower end of the second rod 4b. The swing member 2 is kept in a tendency of horizontal expansion by the action of the first elastic member 9a. The first rod 4a and the second rod 4b are sleeved with each other and can move relative to each other. The downward movement of the water squeezing frame 7 relative to the bracket 3 can push the swing members 2 on both sides to swing downward relative to the bracket 3 and fold. The further downward movement of the water squeezing frame 7 can drive the upper end 1c of the folded foam cotton wiper 1 to contract from top to bottom to achieve water squeezing.

[0042] Specifically, the first rod 4a is sleeved outside the second rod 4b. A locking member 8 is provided inside the bracket 2. The locking member 8 is kept in a tendency of locking the swing member 2 in the horizontal position by the action of the second elastic member 9b. And the downward movement of the water squeezing frame 7 can drive the locking member 8 to move in the unlocking direction. The downward movement of the water squeezing frame 7 first triggers the locking member 8 to move to the unlocking position, and the further downward movement of the water squeezing frame 7 then pushes the swing member 2 to swing downward relative to the bracket 2 and fold.

[0043] The middle part of the locking member 8 is hinged inside the bracket 3. The second elastic member 9b acts on the locking member 8 to make the lower end of the locking member 8 have a tendency to swing outwards. The inner end of the swinging member 2 has a blocking portion 22. The lower end of the locking member 8 swings outwards and abuts above the blocking portion 22 to block the swinging member 2 from swinging downwards relative to the bracket 3. The downward movement of the water squeezing frame 7 can push the upper end of the locking member 8, causing the lower end of the locking member 8 to swing inwards and disengage from the blocking portion 22.

[0044] The working principle and process of this folding foam mop are as follows:

[0045] During cleaning, as Figure 1 shown, the second rod 4b drives the water squeezing frame 7 to be in the upward position. The foam cleaning wipe 1 is horizontally unfolded with the swinging member 2 under the action of the first elastic member 9a (torsion spring). Under the action of the second elastic member 9b, the lower end of the locking member 8 swings outwards and abuts above the blocking portion 22 to block the swinging member 2 from swinging downwards relative to the bracket 3, ensuring that the swinging member 2 does not swing towards the folding direction during the mopping process, which is beneficial for cleaning operations.

[0046] During water squeezing, as Figures 2 to 7 shown, hold the first rod 4a with one hand and push the second rod 4b downwards with the other hand. The water squeezing frame 7 moves downwards accordingly, pushing the upper end of the locking member 8 and causing the lower end of the locking member 8 to swing inwards and disengage from the blocking portion 22. At this stage, the downward movement of the water squeezing frame 7 does not apply a torsional force to the swinging member 2 to make it swing, so that the force of the locking member 8 locking the swinging member 2 and the force of the water squeezing frame 7 pushing the swinging member 2 to swing downwards are independent of each other and do not interfere. The water squeezing frame 7 moves further downwards, and the water squeezing frame 7 can contact the swinging member 2 and drive the swinging member 2 to deflect towards the folding position; the water squeezing frame 7 moves further downwards, driving the upper end 3a of the folded foam cleaning wipe 3 to contract from top to bottom to achieve water squeezing. Move the mop rod 1 up and down within a certain range, and the upper end 1c of the folded foam cleaning wipe 1 repeatedly contracts from top to bottom, finally completing water squeezing.

[0047] The overall cross-section of the foam cleaning wipe 1 is U-shaped. The foam cleaning wipe 1 has a semi-surrounding open structure, so that the foam cleaning wipe 1 semi-covers the swinging member 2, is more firmly combined with the swinging member 2, and also enables the side wall of the swinging member 2 to play a cleaning role. This foam cleaning wipe 1 does not need to be provided with perforations, and the mold does not need to be designed with a core-pulling mechanism, which simplifies the structure of the mold and reduces the consumption of the overall foam. Moreover, due to the structural characteristics of this foam cleaning wipe 1, the mold parting surface can be designed above the top of the foam. During the manufacturing process, hot air can be directly discharged from the parting surface, and the exhaust is smoother. There is no need to additionally set exhaust holes at the top. The structural characteristics of this foam cleaning wipe 1 avoid the accumulation of air bubbles at the top position of the foam cleaning wipe 1 during the manufacturing process, improving the quality of the foam cleaning wipe 1.

[0048] It should be noted that in the description of this embodiment, the orientation or positional relationship indicated by terms such as "front, back", "left, right", "inside, outside", "up, down", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. The terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
