Description

Technical Field

[0001] The present invention relates to a foamed cotton mop that folds and presses down to squeeze water, where the foamed cotton can be colloidal cotton, sponge, Shu cotton or the like. Background Art

[0002] The applicant applied for a Chinese utility model patent "A Miniaturized Folding Foamed Cotton Mop" with the patent number ZL202320949667.0 (publication number CN220655526U), which discloses such a foamed cotton mop structure, including a mop rod, a bracket, and a grip rod. Folding parts are hinged on the left and right sides of the bracket. The folding parts tend to remain horizontal under the action of elastic members, and a foamed cotton wiping object is installed on the folding parts; the bracket is arranged at the lower end of the grip rod, the mop rod is inserted into the grip rod and can axially move relative to the grip rod, and a locking structure is provided between the grip rod and the mop rod. A water squeezing frame that can move up and down is arranged in the bracket, the lower end of the mop rod is connected to the water squeezing frame, and a blocking part located between the two folding parts is provided on the water squeezing frame; in the state where the mop rod and the grip rod are locked, the folding parts are in a horizontal unfolded position, and the blocking part forms a block on the inner ends of the folding parts, thereby locking the folding parts in the horizontal position; when the water squeezing frame moves down, the blocking part can be separated from the block on the inner ends of the folding parts, and when the water squeezing frame continues to move down, it can also push the two side folding parts to swing downward relative to the bracket.

[0003] When squeezing water, one hand holds the grip rod and unlocks the lock between the grip rod and the mop rod at the same time, and the other hand pushes down the mop rod. The water squeezing frame moves down accordingly. The blocking part at the lower end of the water squeezing frame is separated from the block on the inner ends of the folding parts. When the water squeezing frame moves further down, it can contact the folding parts and drive the folding parts to deflect towards the folding position; when the water squeezing frame moves further down, it drives the upper end of the folded foamed cotton wiping object to contract from top to bottom to squeeze water. The mop rod is moved up and down multiple times, and the upper end of the folded foamed cotton wiping object repeatedly contracts from top to bottom, and finally the water squeezing is completed.

[0004] The locking position of the aforementioned mop is only one. After one-time water squeezing is completed, when the mop rod moves up, it may move up to the maximum position under the action of inertia, which will cause the folding parts to return to the horizontal unfolded position again. Therefore, the locking structure needs to be unlocked again for secondary water squeezing next time. For this reason, during the entire water squeezing operation process, it is necessary to hold down the unlock button and move the mop rod reciprocally, and since the water squeezing takes a long time, it also requires both hands to operate, which is inconvenient and not user-friendly. Moreover, when storing, the folding parts are in a horizontal unfolded state, occupying a large space and being inconvenient for storage.

[0005] Therefore, the aforementioned folding and shrinking foamed cotton mop can be further improved. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a foamed cotton mop with a reasonable structure, which can make water squeezing more labor-saving and reduce the storage space, and can be folded and pressed down to shrink and squeeze water.

[0007] The technical solution adopted by the present invention to solve the above technical problems is as follows: a foamed cotton mop with a folded and pressed down to shrink and squeeze water, including a foamed cotton wiping object, a bracket, a first rod, a second rod and a water squeezing frame. Swingable swing members are hinged on the left and right sides of the bracket. The foamed cotton wiping object is constrained on the swing members and can contract or stretch along its length direction. The bracket is connected to the lower end of the first rod, and the water squeezing frame is connected to the lower end of the second rod. The first rod and the second rod are sleeved with each other and can move relative to each other. A first locking structure is provided between the first rod and the second rod. It is characterized in that when the water squeezing frame moves down with the second rod, it can push the swing members on both sides to swing downward and fold. In this position state, the first locking structure locks the first rod and the second rod. The water squeezing frame can further move down with the second rod, driving the upper end of the folded foamed cotton wiping object to contract from top to bottom to achieve water squeezing.

[0008] Further improvement: the above first locking structure is a one-way locking. When the first locking structure is not unlocked, the water squeezing frame cannot move up with the second rod, but the water squeezing frame can further move down with the second rod, driving the upper end of the folded foamed cotton wiping object to contract from top to bottom to achieve water squeezing. This one-way locking structure can better change the water squeezing method. When squeezing water, there is no need to unlock the first locking structure, and the first rod and the second rod can be directly driven to move relative to each other in the water squeezing direction, that is, the water squeezing frame can further move down with the second rod. When the water squeezing frame moves up under the restoring force of the compressed foamed cotton wiping object and reaches the position where the swing members just fold, the first locking structure locks the first rod and the second rod again (to prevent the water squeezing frame from moving up further), making the water squeezing operation more user-friendly.

[0009] As a specific setting method of the first locking structure, the first rod is sleeved outside the second rod. The first locking structure includes a first lock hole, a lock pin and an unlocking button. The first lock hole is provided on the second rod. The lock pin is radially arranged on the first rod and can be inserted into or withdrawn from the first lock hole. The unlocking button is provided on the first rod to drive the radial movement of the lock pin. A return spring for making the lock pin move radially inward is provided on the first rod. A guiding inclined surface for guiding the lock pin out of the first lock hole is provided at the upper part of the first lock hole.

[0010] The second rod is inside the first rod, which can miniaturize the water squeezing rack and basically place it inside the bracket. The overall structure is more compact and smaller, reducing the packaging volume. In this way, the second rod moves downward relative to the first rod to squeeze water, and vice versa for resetting. When the locking pin is inserted into the first locking hole on the second rod, the folding position is locked. The second rod continues to move downward relative to the first rod. Under the guidance of the guiding inclined surface, the locking pin slides along the guiding inclined surface and gradually exits the first locking hole, ensuring that the second rod can further move downward relative to the first rod. The water squeezing rack drives the upper end of the folded foam wiping material to contract from top to bottom to squeeze water. Under the action of the restoring force of the compressed foam wiping material, the second rod moves upward to the folding position, and the locking pin enters the first locking hole again for locking. Since the guiding inclined surface is only provided unidirectionally, in this locked position and without the unlocking state, the second rod can only move in one direction. Only when the unlocking button drives the bolt to exit the first locking hole can the second rod move upward relative to the first rod at the folding position.

[0011] Specifically, the above-mentioned unlocking button is hinged on the first rod, and the upper part of the unlocking button is connected to the locking pin, so that the swing of the unlocking button can drive the locking pin to move radially. The return spring acts on the unlocking button. By pressing the unlocking button, the unlocking of the first locking structure is realized, and the setting of the return spring ensures that the locking pin remains in the first locking hole.

[0012] As another specific setting method of the first locking structure, the above-mentioned second rod is sleeved outside the first rod. The first locking structure includes a first locking hole, a locking pin, and an unlocking button. The first locking hole is provided on the first rod. The locking pin is radially penetrated through the second rod and can be inserted into or withdrawn from the first locking hole. The unlocking button is provided on the second rod to drive the locking pin to move radially. A return spring that causes the locking pin to move radially inward is provided on the second rod, and a guiding inclined surface for guiding the locking pin out of the first locking hole is provided at the lower part of the first locking hole. The water squeezing rack is driven by the outer rod, that is, the second rod is sleeved outside the first rod, and the water squeezing rack is arranged outside the bracket, similar to a sleeve-type water squeezing rack. The principle of realizing unidirectional locking in this way is the same as that of the first method, only the setting positions of the first locking hole, the locking pin, the unlocking button, and the guiding inclined surface are different.

[0013] For further improvement, the above-mentioned swing member has a tendency to remain horizontally unfolded under the action of the first elastic member. A second locking structure is also provided between the first rod and the second rod. In the state where the second locking structure locks the first rod and the second rod, the swing member is in the horizontally unfolded position. The second locking structure locks the first rod and the second rod, and the swing member is in the horizontal cleaning position, without being interfered by the water squeezing rack, which is beneficial for mopping the floor.

[0014] As a specific setting mode of the second locking structure, the above-mentioned first rod is sleeved outside the second rod. The second locking structure includes a second lock hole, a lock pin, and an unlocking button. The second lock hole is arranged on the second rod. The lock pin is radially arranged on the first rod and can be inserted into or withdrawn from the second lock hole. The unlocking button is arranged on the first rod to drive the radial movement of the lock pin. A return spring that causes the lock pin to move radially inward is arranged on the first rod. The second rod is inside the first rod, which can miniaturize the water squeezing frame and basically arrange it inside the bracket, making the overall structure more compact and reducing the packaging volume. Since the first rod is outside the second rod, it is more reasonable to arrange the aforementioned second lock hole on the second rod (inner rod), and it is more reasonable to arrange the lock pin and the unlocking button on the first rod (outer rod).

[0015] As another specific setting mode of the second locking structure, the above-mentioned second rod is sleeved outside the first rod. The second locking structure includes a second lock hole, a lock pin, and an unlocking button. The second lock hole is arranged on the first rod. The lock pin is radially arranged on the second rod and can move radially, so that the lock pin can be inserted into or withdrawn from the second lock hole. The unlocking button is arranged on the second rod to drive the radial movement of the lock pin. A return spring that causes the lock pin to move radially inward is arranged on the second rod. The water squeezing frame is driven by the 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. The principle of realizing one-way locking of this method is the same as that of the first method, only the setting positions of the second lock hole, the lock pin, and the unlocking button are different.

[0016] As an improvement, a locking member is arranged inside the above-mentioned bracket. The locking member is kept in a tendency to lock the swing 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. 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 swing member to swing downward relative to the bracket and fold. When mopping the floor, the locking member always locks the swing member in the horizontal position, and it will not swing passively due to the friction between the wiping object and the ground during mopping. 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 swing member to fold.

[0017] 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. The inner end of the swing member has a blocking portion. The lower end of the locking member swings outward and abuts above the blocking portion to block the swing 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, so that the lower end of the locking member swings inward and disengages from the blocking portion. The second elastic member can be a spring or a torsion spring. The locking member in this structure realizes the locking and unlocking of the swing member through its own swing, involving fewer components, simple structure and convenient assembly. Of course, other existing methods can also be adopted for the locking method.

[0018] Compared with the prior art, the advantages of this foam mop are as follows: With the setting of the first locking structure, at the folding position where the water squeezing frame moves down along with the second rod to push the swing pieces on both sides to swing downward, the first locking structure locks the first rod and the second rod, keeping the swing pieces in the folding position. When squeezing water, the folded swing pieces can be supported on the ground. Then, hold the second rod with both hands and directly press down the second rod to complete water squeezing. After pressing down to the bottom, stop applying force to the second rod. The second rod rebounds under the resilience of the contracted foam wiping material. After rebounding to the folding position, press down the second rod again, and so on to achieve sufficient water squeezing. Since the whole mop is supported by the ground during the entire water squeezing process, it is easier to press down the second rod with both hands. Moreover, the folded swing pieces make the space for the mop to unfold smaller, which is more conducive to storage. BRIEF DESCRIPTION OF THE DRAWINGS

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

[0034] As Figures 1 to 12 shown, it is the first embodiment of the foam cotton mop.

[0035] A foldable and press-down shrinkage water-squeezing foam cotton mop, comprising a foam cotton wiping material 1, a bracket 3, a first rod 4a, a second rod 4b and a water-squeezing frame 7. Swingable swing members 2 are hinged on the left and right sides of the bracket 3. The foam cotton wiping material 1 is constrained on the swing members 2 and can contract or extend along its length direction. The structure of the foam cotton wiping material 1 mounted on the swing members 2 can refer to the background patent.

[0036] 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 first rod 4a and the second rod 4b are sleeved with each other and can move relative to each other. A first locking structure is provided between the first rod 4a and the second rod 4b. As the second rod moves downward, the water-squeezing frame 7 can push the swing members 2 on both sides to swing downward for folding. In this position state (hereinafter referred to as the folding position), the first locking structure locks the first rod 4a and the second rod 4b. The water-squeezing frame 7 can further move downward along with the second rod 4b, driving the upper end 1a of the folded foam cotton wiping material 1 to contract from top to bottom to achieve water squeezing.

[0037] The first locking structure in this embodiment is a one-way locking. In the state where the first locking structure is not unlocked, the water-squeezing frame 7 cannot move upward along with the second rod 4b, but the water-squeezing frame 7 can further move downward along with the second rod 4b, driving the upper end 1a of the folded foam cotton wiping material 1 to contract from top to bottom to achieve water squeezing.

[0038] Specifically, the first rod 4a is sleeved outside the second rod 4b. The first locking structure includes a first lock hole 5a, a lock pin 6, and an unlocking button 9. The first lock hole 5a is provided on the second rod 4b. The lock pin 6 is radially inserted through the first rod 4a and can be inserted into or withdrawn from the first lock hole 5a. The unlocking button 9 is provided on the first rod 4a to drive the radial movement of the lock pin 6. A return spring 91 that causes the lock pin 6 to move radially inward is provided on the first rod 4a. A guiding inclined surface 5a1 for guiding the lock pin 6 out of the first lock hole 5a is provided at the upper part of the first lock hole 5a. The unlocking button 9 is hinged on the first rod 4a, and the upper part of the unlocking button 9 is connected to the lock pin 6, so that the swing of the unlocking button 9 can drive the radial movement of the lock pin 6. The return spring 91 acts on the unlocking button 9.

[0039] The swing member 2 tends to be horizontally unfolded under the action of the first elastic member 10a. A second locking structure is further provided between the first rod 4a and the second rod 4b. In the state where the second locking structure locks the first rod 4a and the second rod 4b, the swing member 2 is in the horizontally unfolded position.

[0040] The first rod 4a is sleeved outside the second rod 4b. The first locking structure in this embodiment can adopt the following structure. The second locking structure includes a second lock hole 5b, a lock pin 6, and an unlocking button 9. The second lock hole 5b is provided on the second rod 4b and is located below the first lock hole 5a. The lock pin 6 is radially inserted through the first rod 4a and can move radially, so that the lock pin 6 can be inserted into or withdrawn from the second lock hole 5b. The unlocking button 9 is provided on the first rod 4a to drive the radial movement of the lock pin 6. A return spring 91 that causes the lock pin 6 to move radially inward is provided on the first rod 4a.

[0041] A locking member 8 is provided inside the bracket 3. The locking member 8 tends to lock the swing member 2 in the horizontal position under the action of the second elastic member 10b. 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 3 and fold.

[0042] The middle part of the locking member 8 is hinged inside the bracket 3. The second elastic member 10b acts on the locking member 8 to make the lower end of the locking member 8 tend to swing. The inner end of the swing member 2 has a blocking portion 21. The lower end of the locking member 8 swings outward and abuts above the blocking portion 21 to block the swing member 2 from swinging downward relative to the bracket 3. The downward movement of the water squeezing frame 7 can push the upper end of the locking member 8, so that the lower end of the locking member 8 swings inward and disengages from the blocking portion 21.

[0043] The working principle and process of this folding foam mopping implement embodiment are as follows:

[0044] During cleaning, such as Figure 1 , 2As shown in FIGS. 4, the second rod 4b drives the water squeezing frame 7 to be in the upward movement position. The foam cotton wiper 1 is horizontally unfolded with the swinging member 2 under the action of the first elastic member 10a (torsion spring). Under the action of the second elastic member 10b, the lower end of the locking member 8 swings outwards and abuts against above the gear 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. The locking pin 6 is inserted into the second locking hole 5b on the first rod 4a, and the water squeezing frame 7 is kept in the uppermost movement position, which is beneficial for cleaning operations.

[0045] When squeezing water, as Figure 3 , 5 ~10 show, hold the first rod 4a with one hand and press the unlocking button 9. The locking pin 6 withdraws from the second locking hole 5b on the first rod 4a. Hold the second rod 4b with the other hand, and at the same time push down the second rod 4b. The water squeezing frame 7 moves down accordingly, pushing the upper end of the locking member 8 to make the lower end of the locking member 8 swing inwards and disengage from the gear portion 22. During 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. When the water squeezing frame 7 moves further down, the water squeezing frame 7 can contact the swinging member 2 and drive the swinging member 2 to deflect towards the folding position. The locking pin 6 automatically inserts into the first locking hole 5a on the first rod 4a under the action of the return spring 91, ensuring that the mop is in the folded position (the water squeezing frame 7 cannot move down with the second rod 4b without unlocking). In this locked position and without the unlocking state, the second rod 4b can only move in one direction. Then support the folded swinging member 2 on the ground, and then hold the second rod 4b with both hands and directly press down the second rod 4b. The second rod 4b continues to move down relative to the first rod 4a. Under the guidance of the guiding inclined surface, the locking pin slides along the guiding inclined surface 5a1 and gradually withdraws from the first locking hole 5a, ensuring that the second rod 4b can move further down relative to the first rod 4a. The water squeezing frame 7 drives the upper end 1a of the folded foam cotton wiper 1 to contract from top to bottom to squeeze water. Under the restoring force of the compressed foam cotton wiper 1, the second rod 4b moves up to the folded position, and the locking pin 6 enters the first locking hole 5a again under the action of the return spring 91 for locking. Press down the second rod 4b again, and so on to achieve sufficient water squeezing. During the whole water squeezing process, because the whole mop is supported by the ground, it is easier to press down the second rod with both hands. Moreover, for the mop with the swinging member locked by the first locking structure after folding, the unfolded space of the mop state is small, which is more conducive to storage.

[0046] As Figure 13 , 14 shown, it is the second embodiment of the foam cotton mop.

[0047] The differences between this embodiment and the first rod embodiment are as follows: The second rod 4b is sleeved outside the first rod 4a, the water squeezing frame 7 is in a sleeve shape, the first locking structure includes a first lock hole 5a, a lock pin 6, and an unlocking button 9. The first lock hole 5a is provided on the first rod 4a. The lock pin 6 is radially penetrated through the second rod 4b and can be inserted into or withdrawn from the first lock hole 5a. The unlocking button 9 is provided on the second rod 4b to drive the radial movement of the lock pin 6. A return spring 91 for making the lock pin 6 have a tendency to move radially inward is provided on the second rod 4b. A guiding inclined surface 5a1 for guiding the lock pin 6 out of the first lock hole 5a is provided at the lower part of the first lock hole 5a. The second locking structure includes a second lock hole 5b, a lock pin 6, and an unlocking button 9. The second lock hole 5b is provided on the first rod 4a and is located above the first lock hole 5a. The lock pin 6 is radially penetrated through the second rod 4b and can be inserted into or withdrawn from the second lock hole 5b. The unlocking button 9 is provided on the second rod 4b to drive the radial movement of the lock pin 6. A return spring 91 for making the lock pin 6 have a tendency to move radially inward is provided on the second rod 4b.

The second locking structure includes a second lock hole (5b), a lock pin (6), and an unlocking button (9). The second lock hole (5b) is provided on the second rod (4b). The lock pin (6) is radially penetrated through the first rod (4a) and can be inserted into or withdrawn from the second lock hole (5b). The unlocking button (9) is provided on the first rod (4a) to drive the lock pin (6) to move radially. A return spring (91) that causes the lock pin (6) to move radially inward is provided on the first rod (4a).

8. The foamed cotton mop for folding, pressing down and squeezing water according to claim 6, characterized in that: The second rod (4b) is sleeved outside the first rod (4a). The second locking structure includes a second lock hole (5b), a lock pin (6), and an unlocking button (9). The second lock hole is provided on the first rod (4a). The lock pin (6) is radially penetrated through the second rod (4b) and can move radially, such that the lock pin (6) can be inserted into or withdrawn from the second lock hole (5b). The unlocking button (9) is provided on the second rod (4b) to drive the lock pin (6) to move radially. A return spring (91) that causes the lock pin (6) to move radially inward is provided on the second rod (4b).

9. The foamed cotton mop for folding, pressing down and squeezing water according to claim 1, wherein: A locking member (8) is provided inside the bracket (3). The locking member (8) is urged by a second elastic member (10b) to maintain a tendency to lock the swing member (2) in the horizontal position. 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 (3) and fold in half.

10. The foamed cotton mop that folds, presses down, contracts and squeezes water according to claim 9, wherein: The middle part of the locking member (8) is hinged inside the bracket (3). The second elastic member (10b) acts on the locking member (8) to cause the lower end of the locking member (8) to have a tendency to swing. The inner end of the swing member (2) has a blocking portion (21). The lower end of the locking member (8) swings outward and abuts above the blocking portion (21) to block the swing member (2) from swinging downward 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 inward and disengage from the blocking portion (21).
