Description

Technical Field

[0001] The invention belongs to the technical field of collodion mops, in particular to a collodion mop. Background Art

[0002] The collodion has a strong water absorption capacity and can fully ensure the cleaning work of the cotton head, so the collodion mop is widely favored by consumers. There are two types of collodion mops on the market: the first type is the old-fashioned collodion mop, as shown in Chinese patent CN201610233209.1. When squeezing water in the old-fashioned collodion mop, the handle is pulled to drive the collodion head to move upward horizontally through the pull rod. The collodion head passes between the squeezing rods of the squeezing rack. Because the squeezing rod has an elastic force that maintains a clamping tendency, the collodion head passing through the squeezing rod will be squeezed by the squeezing rod to squeeze water; the second type is the squeezing rack type squeezing collodion mop, as shown in Chinese patent CN20 1710060588.3, ​​comprising a mop rod and a foam head, the foam head is rotatably connected to the lower end of the mop rod, a water squeezing handle is provided on the mop rod, the water squeezing handle and the mop rod can slide up and down relatively, the water squeezing handle is connected to a water squeezing head through a connecting rod, the water squeezing head has a through hole whose shape matches the cross-section of the foam head, the foam head can be rotated to be parallel to the mop rod and face the through hole, and a squeezing component is provided in the through hole for squeezing water from the foam head passing through the through hole.

[0003] The two dehydration methods have the following defects:

[0004] 1. Disadvantage 1 of the first old-fashioned rubber cotton mop: The water squeezing method is that the squeezing frame moves along the height direction of the rubber cotton head to achieve water squeezing. In order to ensure that the entire rubber cotton head can be squeezed by the squeezing rod, the lateral length of the squeezing rod must be close to the length of the rubber cotton head. This results in the overall lateral length of the squeezing part being very long, which appears to be relatively bulky. In addition, the contact area between the squeezing rod and the rubber cotton head is large during the squeezing process, and the friction force during squeezing is greatly increased. In addition, there are generally multiple rows of squeezing rods on the front or back side, which requires more consumables and the cost of the squeezing frame is relatively high.

[0005] 2. Disadvantage 2 of the first old-fashioned rubber cotton mop: Due to the particularity of the squeezing frame structure, the rubber cotton head and the mop rod must be fixedly connected, and the rubber cotton head cannot be completely separated from the squeezing frame, that is, the rubber cotton head cannot rotate relative to the mop rod. When mopping the floor, it is inconvenient to mop in certain occasions, such as corners, and the adaptability of mopping is poor.

[0006] 3. Disadvantages of the second new type of squeezing rack type squeezing cotton mop: Although it solves the problem that the cotton head of the first type of old-fashioned cotton mop cannot rotate relative to the mop rod, it ignores the strong water absorption of the cotton, and adopts long-distance squeezing. The squeezing head squeezes water locally on the cotton head. The water just squeezed out by the user during the squeezing process will be quickly absorbed back by the unsqueezed cotton head. This is also the reason why the old-fashioned cotton mop requires multiple rows of squeezing rods. Therefore, after multiple squeezings, the cotton head of the squeezing rack type squeezing cotton mop of method 2 is still relatively wet, and a good squeezing effect cannot be achieved; moreover, the squeezing device cannot clean the cotton head and has a single function. Summary of the invention

[0007] The purpose of the present invention is to provide a collodion mop which has a simple and stable structure, can be used to clean the surface of the cotton head and has a good water squeezing effect.

[0010] The mop rod is provided with a water squeezing rack, which can move along the mop rod. When squeezing water, the mop head can be rotated until the length direction of the cotton head is substantially parallel to the mop rod and aligned with the water squeezing rack. The water squeezing rack slides upward along the length direction of the cotton head and squeezes the cotton head to achieve the squeezing or release of the cotton head inside the mop head along the length direction of the cotton head.

[0011] When mopping the floor, the cotton head is completely separated from the water squeezing rack.

[0012] The water squeezing rack is provided with a supporting part. When squeezing water, the supporting part is against one end of the cotton head and compresses the cotton head. The cotton head is flattened in the length direction under the drive of the supporting part.

When the squeezing frame presses the cotton head, the cotton head abuts against the first limiting plate;

[0016] The squeezing water rack is provided with a supporting part. When squeezing water, the supporting part of the squeezing water rack is pressed against the supporting plate. The supporting plate and the cotton head move along the transverse support rod to realize the flattening of the cotton head in the length direction.

[0017] A first limit plate is fixedly provided at one end of the support frame, and a second limit plate is fixedly provided at the other end of the support frame. At least two transverse support rods are provided between the first limit plate and the second limit plate. The abutment plate and the cotton head are passed through the transverse support rods and limited between the first limit plate and the second limit plate.

[0018] The water squeezing rack extends at least one protrusion, and the protrusion on one side of the cotton head is the abutment portion. The second limiting plate is provided with a space avoidance portion. When the water squeezing rack is squeezing water, the protrusion passes through the space avoidance portion and then abuts against the abutment plate.

[0019] A positioning mechanism is provided between the second limiting plate and the abutting plate;

[0020] The positioning mechanism includes: a buckle provided on the second limit plate and a slot provided on the abutting plate and adapted to the buckle; or, the positioning mechanism includes: a slot provided on the second limit plate and a buckle provided on the abutting plate and adapted to the buckle;

[0021] When the cotton head is reset, the buckle and the slot engage.

[0022] The end of the water squeezing frame is provided with a retaining frame, and the middle of the water squeezing frame is provided with the abutting portion. When squeezing water, the cotton head passes through the retaining frame and then abuts against the abutting portion.

[0023] A brush is detachably provided on the inner side of the retaining frame. When the cotton head passes through the retaining frame, the brush can clean the surface of the cotton head, and when the abutting portion moves away from the cotton head, the brush assists the cotton head in resetting.

[0024] The mop head is provided with a lower hinge seat, the lower end of the handle rod is provided with an upper hinge seat, the upper hinge seat and the lower hinge seat are rotatably connected via a pin shaft, a latch is provided inside the upper hinge seat, a spring is provided at the rear of the latch, the spring applies a force to the latch to move outward, a lateral recess for limiting the latch is provided on the lower hinge seat, and when the mop head can be rotated until the length direction of the cotton head is basically parallel to the mop rod, the latch is limited in the lateral recess.

[0025] Compared with the prior art, the present invention has the following outstanding and beneficial technical effects:

[0026] 1. Since the present invention adopts squeezing water from the length direction of the cotton head, it is necessary to avoid the problem of the cotton head sucking back during the squeezing process. Therefore, when squeezing water, the squeezing frame of the rubber cotton mop of the present invention slides downward along the length direction of the cotton head and squeezes the cotton head to achieve the flattening or release of the cotton head inside the mop head along the length direction of the cotton head. The entire cotton head is squeezed at all times in a transverse flattening manner, which effectively squeezes water and avoids the cotton head sucking back liquid, thereby ensuring the effectiveness of squeezing water. In addition, the squeezing frame provided on the mop is used for squeezing water, and no additional accessories are required, which is simple to operate.

[0027] 2. The water squeezing rack of the present invention is provided with a supporting part. When squeezing water, the supporting part is against one end of the cotton head and compresses the cotton head. The cotton head is flattened in the length direction under the drive of the supporting part. The force is directly applied to one end of the cotton head through the supporting part of the water squeezing rack to squeeze water. The force is more accurate. The cotton head is directly driven from one end in the length direction to achieve more effective water squeezing. In order to avoid deformation of the cotton head during the flattening process, the cotton head is penetrated on the transverse support rod through its own through hole. The transverse support rod is used to hold and guide the cotton head for squeezing water, so that the water squeezing process is more stable. When the supporting part moves away from the cotton head, the cotton head can be reset under its own deformation force. The reset characteristics of the cotton head itself are utilized. No additional reset device is required, so that the product structure is simpler.

[0028] 3. The transverse support rod of the present invention is also provided with a support plate, which slides on the transverse support rod, and is fixed to one end of the cotton head. The support plate is used to auxiliary support the cotton head and allows the water squeezing frame to lean against the support plate when squeezing the cotton head, so that the leaning is more stable. A first limiting plate is fixedly provided at one end of the support frame, and the first limiting plate and the support plate are respectively arranged at both ends of the cotton head. When the water squeezing frame presses the cotton head, the cotton head leans against the first limiting plate. The first limiting plate is an anti-slip plate and abutment plate of the cotton head, which prevents the cotton head from detaching from one end and provides the cotton head with abutment when squeezing water, thereby ensuring the stability of the water squeezing structure. In addition, a first limiting plate is fixedly provided at one end of the support frame, and a second limiting plate is fixedly provided at the other end of the support frame. At least two transverse support rods are provided between the first limiting plate and the second limiting plate. The abutment plate and the cotton head are passed through the transverse support rods and limited between the first limiting plate and the second limiting plate. In addition to being an anti-slip plate and abutment plate for the cotton head, the first limiting plate also supports at least two transverse support rods between the first limiting plate and the second limiting plate to ensure the stability of the structure.

[0029] 4. A positioning mechanism is provided between the second limiting plate and the abutting plate of the present invention. The positioning mechanism includes: a buckle provided on the second limiting plate and a slot provided on the abutting plate that matches the buckle; or a slot provided on the second limiting plate and a buckle provided on the abutting plate that matches the buckle. When the cotton head is reset, the buckle and the slot are engaged. The positioning mechanism is used to protect the user during use. Since the cotton head squeezes water in the length direction, one end of the cotton head is movable. If it is used to mop the floor horizontally during use, lateral contraction may occur. The positioning mechanism is used to position the structure so that the end of the cotton head that will contract is positioned, ensuring that the rubber cotton mop does not contract laterally during use and ensuring the stability of the structure.

[0030] 5. The end of the water squeezing rack of the present invention is provided with a retaining frame, and the abutting part is provided in the middle of the water squeezing rack. When squeezing water, the cotton head passes through the retaining frame and then abuts against the abutting part. The retaining frame can prevent the mop head from tilting and causing a series of collisions when squeezing water. Moreover, the cotton head must pass through the retaining frame before squeezing water, so as to detect the alignment of the mop head with the water squeezing rack before squeezing water and maintain protection during the squeezing process; and, a brush is detachably provided on the inner side of the retaining frame. When the cotton head passes through the retaining frame, the brush can clean the surface of the cotton head, and when the abutting part moves away from the cotton head, the brush assists the cotton head to reset. The reset force of the cotton head itself may not be able to effectively realize the fastening between the slot and the buckle. The brush can also assist the slot and the buckle of the positioning mechanism to fasten, so as to ensure the stability of the structure. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0048] The present invention will be further described below with reference to specific embodiments of the present invention. Figure 1-16 As shown:

[0049] A collodion mop comprises a mop rod 1, a mop head 2 is movably provided at the end of the mop rod 1, a cotton head 25 is provided on the mop head 2, a water squeezing frame 3 is sleeved on the mop rod 1, the water squeezing frame 3 can move along the mop rod 1, the mop head 2 can be rotated until the length direction L of the cotton head is substantially parallel to the mop rod 1 and aligned with the water squeezing frame 3, and this state is the water squeezing state.

[0050] The cotton head 25 is movably arranged on the mop head 2 and the cotton head 25 / part of the cotton head 25 can move laterally in the mop head 2. The cotton head 25 may not be fixed at both ends or one end of the cotton head 25 may be fixed on the mop head. Preferably, one end of the cotton head 25 is fixed so that part of the cotton head 25 can move laterally in the mop head 2.

[0051] When squeezing water, the squeezing frame 3 slides upward along the length direction of the cotton head 25 and squeezes the cotton head 25 to achieve the squeezing or release of the cotton head 25 along the length direction L inside the mop head 2.

[0052] When mopping the floor, the cotton head 25 is completely separated from the water squeezing frame 3 .

[0053] When squeezing water from the length direction of the cotton head, the problem of the cotton head 25 sucking back during the squeezing process must be avoided. Therefore, when squeezing water with the rubber cotton mop of the present invention, the squeezing frame 3 slides downward along the length direction of the cotton head and squeezes the cotton head 25 to achieve the flattening or release of the cotton head 25 inside the mop head 2 along the length direction of the cotton head. The entire cotton head 25 is squeezed all the time in a transverse flattening manner, and the water is effectively squeezed to avoid the cotton head 25 sucking back the liquid, thereby ensuring the effectiveness of squeezing water. In addition, squeezing water using the squeezing frame 3 provided on the mop does not require additional accessories and is simple to operate.

[0054] The squeezing water rack 3 is provided with a butting portion 311, which is any position on the squeezing water rack 3 or a certain end face of a butting component installed on the squeezing water rack 3. As long as the squeezing water rack 3 pushes the cotton head 25, when squeezing water, the butting portion 311 butts against one end of the cotton head 25 and compresses the cotton head 25, and the cotton head 25 is flattened in the length direction under the drive of the butting portion 311. When the butting portion 311 moves away from the cotton head 25, the cotton head 25 can be reset under its own deformation force. The butting portion 311 of the squeezing water rack 3 directly applies a force to one end of the cotton head 25 to squeeze water, and the force application is more accurate. The cotton head 25 is directly driven from one end in the length direction to achieve more effective squeezing water.

[0055] The mop head 2 includes a support frame 21, which is hinged to the mop rod 1. At least one transverse support rod 26 is provided in the support frame 21. A through hole is provided in the length direction of the cotton head, which is marked in the attached figure. The cotton head 25 is penetrated on the transverse support rod 26 through the through hole, and the cotton head 25 / part of the cotton head 25 can move on the transverse support rod 26. In order to prevent the cotton head 25 from deforming during the flattening process, the cotton head 25 is penetrated on the transverse support rod 26 through its own through hole, and the cotton head 25 is maintained and guided by the transverse support rod 26 to make the squeezing process more stable. When the abutting portion 311 moves away from the cotton head 25, the cotton head 25 can be reset under its own deformation force, and the reset characteristics of the cotton head 25 are used, and no additional reset device is required, so that the product structure is simpler.

[0056] The transverse support rod 26 is also provided with a support plate 24, which slides on the transverse support rod 26, and the support plate 24 is fixed to one end of the cotton head 25, and the support plate 24 is used to assist in supporting the cotton head 25 and to make the squeezing frame 3 press against the support plate 24 when squeezing the cotton head 25, so that the support is more stable.

[0057] One end of the support frame 21 is fixedly provided with a first limiting plate 23, and the first limiting plate 23 and the abutting plate 24 are respectively arranged at the two ends of the cotton head. When the squeezing frame 3 presses the cotton head 25, the cotton head 25 abuts against the first limiting plate 23. The first limiting plate 23 is an anti-slip plate and abutting plate of the cotton head 25, which prevents the cotton head 25 from detaching from one end and gives the cotton head 25 abutment when squeezing water, ensuring the stability of the squeezing structure. When squeezing water, the abutting portion 311 of the squeezing frame 3 abuts against the abutting plate 24, and the abutting plate 24 and the cotton head 25 move along the transverse support rod 26 and realize the flattening of the length direction of the cotton head. Preferably, one end of the cotton head 25 is connected and fixed to the first limiting plate 23, and one end of the cotton head 25 is indirectly fixed to the support frame 21, limiting the degree of freedom of the cotton head 25, and making the movement of the cotton head 25 more controllable.

[0058] Preferably, at least one guide groove 242 is provided at the contact end of the support frame 21 on the abutment plate 24, and a guide rib 211 adapted to the guide groove 242 is provided on the inner side of the support plate 24. The guide rib 211 is a longitudinal convex rib, and auxiliary support is provided by the guide rib 211 and the guide groove to ensure that the abutment plate 24 slides effectively on the transverse support rod 26 to avoid lateral tilting. Fig.16 shown.

[0059] A first limiting plate 23 is fixedly provided at one end of the support frame 21, and a second limiting plate 22 is fixedly provided at the other end of the support frame 21. The first limiting plate 23 and the second limiting plate 22 are preferably fixedly connected by fasteners, and the fixing members may be bolts / screws / rivets, etc. Since the first limiting plate 23 and the second limiting plate 22 are subjected to greater forces, the fixation between the three needs to be stable. At least two transverse support rods 26 are provided between the first limiting plate 23 and the second limiting plate 22, and preferably two transverse support rods 26 are provided to prevent the cotton head 25 from twisting laterally. The abutment plate 24 and the cotton head 25 are inserted on the transverse support rods 26 and limited between the first limiting plate 23 and the second limiting plate 22. In addition to being an anti-slip plate and abutment plate for the cotton head 25, the first limiting plate 23 also supports at least two transverse support rods 26 between the first limiting plate 23 and the second limiting plate 22 to ensure the stability of the structure.

[0060] Preferably, when the cotton head 25 is installed between the first limiting plate 23 and the second limiting plate 22 and is not squeezed, the cotton head 25 is also compressed and limited between the first limiting plate 23 and the second limiting plate 22. This structure makes the resetting of the cotton head 25 more stable and effective.

[0061] The squeezing rack 3 extends at least one protrusion 31, preferably two protrusions 31 are provided. Figure 1-3 As shown, the protrusion 31 is the abutting portion 311 on one side of the cotton head 25, and the second limiting plate 22 is provided with a clearance portion 222. When the water squeezing rack 3 is squeezing water, the protrusion 31 passes through the clearance portion 222 and abuts on the abutting plate 24. The clearance portion 222 can avoid interference between parts, and the clearance portion 222 can avoid misoperation. The protrusion 31 can squeeze the cotton head 25 only after passing through the clearance portion 222.

[0062] A positioning mechanism is provided between the second limiting plate 22 and the abutting plate 24;

[0063] The positioning mechanism includes: a buckle 221 provided on the second limiting plate 22 and a slot 241 provided on the abutting plate 24 and adapted to the buckle 221; or, the positioning mechanism includes: a slot provided on the second limiting plate and a buckle provided on the abutting plate and adapted to the buckle; both solutions are acceptable.

[0064] When the cotton head 25 is reset, the buckle 221 and the slot 241 are engaged. The positioning mechanism is used to protect the user during use. Since the cotton head 25 squeezes water in the length direction, one end of the cotton head 25 is movable. If the cotton head 25 is used to mop the floor horizontally, the cotton head may shrink laterally. The positioning mechanism is used to position the structure so that the shrinking end of the cotton head 25 is positioned, ensuring that the rubber cotton mop does not shrink laterally during use and ensuring the stability of the structure.

[0065] The end of the squeezing rack 3 is provided with a retaining frame 32, and the middle of the squeezing rack 3 is provided with the abutting portion 311. When squeezing water, the cotton head 25 passes through the retaining frame 32 and then abuts against the abutting portion 311. The retaining frame 32 can prevent the mop head from tilting during squeezing water and causing a series of collisions and other problems. Moreover, the cotton head 25 must first pass through the retaining frame 32 before squeezing water, so as to detect that the mop head 2 is aligned with the squeezing rack 3 before squeezing water and maintain protection during the squeezing process. Figure 1-3 As shown, the cotton head enters the retainer but the abutment portion does not squeeze the cotton head. Figure 6-8 As shown, the cotton head enters the retaining frame and the abutment portion squeezes water out of the cotton head. In actual operation, the cotton head 25 must first pass through the retaining frame 32 before the cotton head 25 can be squeezed out.

[0066] In addition, a brush 33 is detachably provided on the inner side of the retainer 32. When the cotton head 25 passes through the retainer 32, the brush 33 can clean the surface of the cotton head 25, and when the abutment portion 311 moves away from the cotton head 25, the brush 33 assists the cotton head 25 in resetting. The reset force of the cotton head 25 itself may not be able to effectively achieve the engagement between the slot 241 and the buckle 221. The brush 33 can also assist the slot 241 and the buckle 221 of the positioning mechanism in engaging to ensure the stability of the structure.

[0067] The mop head 2 is provided with a lower hinge seat 27, and the lower end of the handle rod 1 is provided with an upper hinge seat 10. The upper hinge seat 10 and the lower hinge seat 27 are rotatably connected via a pin shaft 28 to achieve free rotation of the mop head 2, making the product more flexible. A latch 12 is provided inside the upper hinge seat 10, and a spring 13 is provided at the rear of the latch 12. The spring 13 gives the latch 12 a force to move outward and always abuts against the outer side wall of the lower hinge seat 27. A lateral recess 272 for limiting the latch 12 is provided on the lower hinge seat 27. When the mop head 2 can be rotated until the length direction L of the cotton head is basically parallel to the mop rod 1, the latch 12 is limited in the lateral recess 272. In fact, an end recess 271 is also provided on the lower hinge seat 27. The end recess 271 and the lateral recess 272 are used for positioning between the mop head 2 and the handle rod 1. Applying a certain external force can overcome the force of the spring 13 to make the latch 12 disengage from the end recess 271 and the lateral recess 272 of the lower hinge seat 27. The end recess 271 is used to longitudinally maintain the rubber cotton mop, and the lateral recess 272 is used to maintain the water squeezing state of the rubber cotton mop. The present invention only has one lateral recess 272. The main reason is that the squeezing direction is singular, so the latch 12 structure only maintains the squeezing direction. Only when the latch 12 enters the lateral recess 272 and is in a maintained state, can effective squeezing be performed.

[0068] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
