Description

Technical Field

[0001] This invention relates to the field of cleaning tool technology, and more specifically to a mop with a built-in cleaning chamber. Background Technology

[0002] In daily life, when using a mop to clean the floor, the mop head needs to be frequently rinsed and wrung out in a cleaning bucket or basin. This method has the following inconveniences: First, a water bucket must be specially configured and carried, which takes up space and is inconvenient to move; Secondly, during the rinsing process, the water in the bucket gets dirty after only a few rinses, requiring repeated emptying of the dirty water and replacement with fresh water. This process is cumbersome, wastes water resources, and the frequent bending over to change the water also puts a strain on the user's physical strength and back. Third, although some hands-free mops have integrated squeegee or wringer mechanisms, they still rely on external containers for washing and dehydration, and the bucket still needs to be cleaned after use, so they cannot achieve true hands-free washing. Fourth, with repeated use, dirt tends to accumulate at the bottom of traditional external cleaning buckets, making them difficult to clean thoroughly. Over time, this accumulation affects the cleaning effect and hygiene.

[0003] Therefore, there is a need for a mop that does not require an external cleaning container, can complete cleaning and dehydration within the mop's own structure, and can effectively prevent dirt buildup. Summary of the Invention

[0004] The purpose of this invention is to provide a mop with a built-in cleaning chamber. By setting a cleaning chamber inside the mop handle, the mop head can be directly rinsed and wrung out inside the handle, eliminating the need for a separate cleaning bucket or basin. At the same time, after cleaning, dirty water is drained through the opening to prevent dirt from accumulating. To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A mop with a built-in cleaning chamber includes an outer rod, a mop head, an opening, and a drive mechanism. The outer rod is a hollow cavity that forms the cleaning chamber. The opening communicates with the cleaning chamber and is either an openable / closable opening or an elastically constrained opening. The mop head can be retracted into the cleaning chamber. The drive mechanism is used to drive the mop head to retract or extend from the cleaning chamber.

[0006] Furthermore, the opening can be an openable and closable opening, capable of switching between an open state and a closed state.

[0007] Furthermore, the opening can be an elastically constrained opening, passively adapting to the entry and exit of the mop head through its own elasticity, and providing a constraining force when the mop head passes through. The elastically constrained opening can be normally open or normally closed in its natural state.

[0008] Furthermore, the opening may include a water inlet and / or a drain outlet. The water inlet is used to inject clean water or a cleaning solution containing detergent into the cleaning chamber, and the drain outlet is used to drain the liquid from the cleaning chamber. The water inlet and the drain outlet may be the same opening, serving both water injection and drainage functions.

[0009] Furthermore, the drive mechanism may include at least one of the following: an inner rod drive, a magnetic drive mechanism, an electric drive mechanism, a connecting rod linkage mechanism, or a push-button drive mechanism. The mop head may be cleaned in the cleaning chamber by one or more of the following: rinsing, vibration cleaning, ultrasonic cleaning, or rotational cleaning.

[0010] Furthermore, when the drive mechanism includes an inner rod, the inner rod passes through the outer rod and can move relative to the outer rod. This movement includes axial sliding and / or circumferential rotation. The axial sliding is used to achieve reciprocating motion of the mop head within the outer rod cavity, thus achieving rinsing. The circumferential rotation, in conjunction with external constraints, applies squeezing and / or torsional forces to the mop head, achieving dehydration.

[0011] Furthermore, the mop head and the inner rod can be non-connected, fixedly connected, or detachably connected. Similarly, the mop head and the outer rod can be non-connected, detachably connected, or fixedly connected. In a non-connected fit, there is no fixed connection structure between the mop head and the outer rod; the fit is achieved through external constraints. In a fixed connection, the mop head and the outer rod are in a non-detachable, fixed assembly relationship. In a detachable connection, the mop head and the outer rod are in a separable assembly relationship.

[0012] Furthermore, a limiting structure can be provided between the outer rod and the inner rod to limit the axial movement range of the inner rod relative to the outer rod, prevent the inner rod from coming out of the outer rod, or limit the maximum distance the mop head is pushed out.

[0013] Furthermore, the outer rod may be provided with a stabilizing structure to limit the radial sway of the outer rod relative to the mop head or inner rod when mopping.

[0014] Furthermore, the outer rod may be provided with hanging holes and / or a grip structure, which may be at least one of a handle, armrest, or grip ring, to facilitate gripping and applying force when mopping or hanging for storage. The outer rod may also be provided with an observation structure for observing the inside of the cleaning chamber, such as a transparent observation window, observation hole, or water level gauge.

[0015] Furthermore, the mop head can be made of one or more of the following materials: cotton cloth, fiber cloth, PVC foam, sponge, or microfiber. The beneficial effects of this invention are as follows:

[0016] 1. The cleaning chamber is integrated inside the mop handle, so users do not need to carry or buy a separate cleaning bucket to rinse and wring the mop head. Both washing and wringing can be done inside the mop handle, eliminating the need for users to touch dirty water with their hands. This hands-free operation greatly improves the convenience of use and saves storage space.

[0017] 2. The washing and wringing processes are completed through multiple drive mechanisms and dehydration methods. The structure is simple, can be operated manually, and is highly practical.

[0018] 3. After washing and wringing, the dirty water can be drained through the opening, effectively solving the problem of dirt accumulation caused by long-term use of traditional external cleaning buckets, making it more hygienic.

[0019] 4. The outer rod is equipped with hanging holes and / or a grip structure, which can be hung on the wall or easily gripped for force, further saving storage space and keeping the home tidy. Attached Figure Description

Detailed Implementation

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments. These embodiments are only used to explain the present invention and are not intended to limit the scope of protection of the present invention. Example 1: Detachable Sealed Type

[0034] Reference Figure 1 and Figure 2 In this embodiment, the outer rod 1 is a hollow cavity, forming a cleaning chamber. It also includes an inner rod 2, which passes through the outer rod 1 and can slide axially and rotate circumferentially relative to the outer rod 1. The mop head 3 is connected to the lower end of the inner rod 2, forming a linkage structure with the inner rod 2, and can be retracted into the cleaning chamber.

[0035] The inner wall of the outer rod 1 is provided with a stable connection structure 23, which is sleeved on the inner rod 2 to limit the radial sway of the outer rod 1 relative to the inner rod 2.

[0036] The lower end of the outer rod 1 is provided with a ground-fixed base 4. A detachable sealing connection structure is provided between the base 4 and the lower end of the outer rod 1, which is a threaded connection or a snap-fit ​​connection. When the lower end of the outer rod 1 is connected to the base 4, the opening at the lower end of the outer rod 1 is in a closed state, and the cleaning chamber is sealed; when the lower end of the outer rod 1 is separated from the base 4, the opening is in an open state, the mop head 3 can be extended, and dirty water can be drained.

[0037] The lower surface of the base 4 can be equipped with an anti-slip pad, suction cup, or snap-fit ​​structure to fit with the floor drain, so as to fix it to the ground.

[0038] During cleaning, the mop head 3 is retracted into the cleaning chamber, the lower end of the outer rod 1 is connected to the base 4 to close the opening, cleaning liquid is injected from the water inlet 5, and the inner rod 2 is pushed and pulled to drive the mop head 3 to rinse up and down in the cleaning chamber.

[0039] When wringing dry, remove the outer rod 1 from the base 4, fully opening the lower end of the outer rod 1. Place the lower end of the outer rod 1 upright on the ground, with the mop head 3 positioned between the lower end of the inner wall of the cleaning chamber and the ground. Rotate the inner rod 2; the mop head 3 is twisted and wrung dry under the pressure of the ground and the inner wall of the outer rod 1. Simultaneously, push the inner rod 2 downwards to squeeze out excess water, which is then discharged directly from the opening. When mopping, the mop head 3 extends from the outer rod 1 along with the inner rod 2 to mop the floor.

[0040] In this embodiment, the mop head 3 is connected to the lower end of the inner rod 2, and the mop head 3 is not connected to the lower end of the outer rod 1. The mop head 3 is wrung out by pressing the ground with the inner wall of the cleaning chamber and the inner rod 2. Example 2: Elastic diaphragm flip-type

[0041] Reference Figure 3 A, Figure 3 B and Figure 3 C. In this embodiment, the lower end of the outer rod 1 is provided with an integrated elastic diaphragm 7. It also includes an inner rod 2, which passes through the outer rod 1. The upper end of the mop head 3 is connected to the lower end of the inner rod 2, and the lower end of the mop head 3 is fixedly connected to the inner side of the lower end of the outer rod 1. One end of the elastic diaphragm 7 is connected to the lower end of the outer rod 1, and the other end is a free end, which is open.

[0042] Figure 3 In the usage state (A), the mop head 3 extends from the elastic diaphragm 7 to mop the floor.

[0043] Figure 3 B is when the mop head 3 is drawn upward into the cleaning chamber by the inner rod 2, and the mop head 3 and the inner rod 2 cause the free end of the elastic diaphragm 7 to flip upward.

[0044] Figure 3 With the mop upright on the ground (C), the elastic diaphragm 7 is pressed into a closed position by the mop head 3, closing the opening. At this time, cleaning fluid is injected through the water inlet 5, and the inner rod 2 is pushed and pulled to move the mop head 3 up and down for a rinsing effect. During cleaning, the mop is upright on the ground, and the liquid pressure and the up-and-down rinsing force act on the surface of the elastic diaphragm 7, making it adhere more tightly and achieving a self-sealing effect.

[0045] When wringing out, push the mop head 3 downwards, causing the elastic diaphragm 7 to flip back to the open position, allowing dirty water to drain out. Rotate the inner rod 2 to wring out the mop head 3, allowing water to drain directly. The upper part of the inner rod 2 has a hanging hole 10 for easy hanging and storage.

[0046] In this embodiment, the two ends of the mop head 3 are fixedly connected to the lower end of the inner rod 2 and the inner side of the lower end of the outer rod 1, respectively. The mop head 3 can be directly wrung out by rotating the inner rod 2. Example 3: Sealing Plate Type

[0047] Reference Figure 1 and Figure 4In this embodiment, multiple sealing plates 6 are provided on the inner wall of the lower end of the outer rod 1. Each sealing plate 6 is evenly distributed along the circumference and automatically converges towards the center under natural conditions. Gaps are left at the openings to allow liquid to seep out.

[0048] The lower inner side of the outer rod 1 is provided with a slot 12. The bottom of the mop head 3 is provided with a retaining part 11 for retracting the mop cloth. The retaining part 11 can be made of a soft surface material to reduce the contact friction with the ground when mopping.

[0049] It also includes an inner rod 2, which passes through the outer rod 1. The mop head 3 is connected to the lower end of the inner rod 2.

[0050] During cleaning, the mop head 3 is retracted into the cleaning chamber, and the sealing plate 6 automatically converges towards the center due to its own elasticity. The mop is then placed upright on the ground, with the lower end of the sealing plate 6 in contact with the ground. The ground's reaction force pushes the sealing plate 6 upwards, ensuring a tight seal between the sealing plate 6 and the lower end face of the outer rod 1, achieving an end-face seal. Cleaning fluid is injected through the water inlet 5, and the inner rod 2 is pushed and pulled to move the mop head 3 up and down for rinsing.

[0051] When wringing out, lift the lower end of the mop off the ground, and the dirty water will flow out through the gap in the sealing plate 6 under its own weight. Pull the mop head 3 upward, and the locking piece 11 will engage with the slot 12. Rotate the inner rod 2 to wring out the mop head 3. After wringing out, apply slight force to push the mop head 3 downward, and the locking piece 11 will disengage from the slot 12, separating the mop head 3 from the outer rod 1. When mopping, simply extend the mop head 3 out of the outer rod 1 to mop the floor.

[0052] The cross-sectional shape of the insert 11 is triangular, quadrilateral or dart-shaped, and the slot 12 matches the insert 11. After being inserted, it restricts the rotation and ensures that the torsional force is effectively transmitted when wringing.

[0053] In this embodiment, the mop head 3 is fixedly connected to the inner rod 2 and detachably connected to the lower end of the outer rod 1. When wringing, the mop head is subjected to a rotational torsional force to complete the rotational wringing and dehydration. Example 4: Conical Normally Open Elastic Hole Type

[0054] Reference Figure 1 , Figure 5 A and Figure 5 B. In this embodiment, the lower end of the outer rod 1 is provided with a tapered elastic hole 13, made of silicone or TPE. The larger end of the tapered elastic hole 13 faces inward, and the smaller end faces outward, changing with the movement of the inner rod 2. In its natural state, the smaller end remains open. When the inner rod 2 is pushed out, the smaller end of the tapered elastic hole 13 is expanded outward; when the inner rod 2 is retracted and passed through, the tapered elastic hole 13 automatically returns to its natural state. The opening communicates with the cleaning chamber and is an elastically constrained opening.

[0055] It also includes an inner rod 2, which passes through the outer rod 1, and the surface of the inner rod 2 is provided with a groove. The mop head 3 is connected to the lower end of the inner rod 2.

[0056] During cleaning, the mop head 3 is retracted into the cleaning chamber, and the mop is placed upright on the ground. The mop's own weight, combined with the ground's reaction force, prevents the mop head 3 from being pushed out of the elastic hole 13. The conical elastic hole 13 passively restrains the cleaning fluid by its own elastic contraction force, without the need for active sealing. Cleaning fluid is injected through the water inlet 5, and the inner rod 2 is pushed and pulled to move the mop head 3 up and down for rinsing.

[0057] After cleaning, push the inner rod 2 downwards. When the mop head 3 passes through the conical elastic hole 13, it is squeezed and some water is initially discharged. After it has completely passed through, the dirty water is guided downwards through the groove on the surface of the inner rod 2 and discharged from the edge of the conical elastic hole 13.

[0058] When wringing, first drain the dirty water from the cleaning chamber. Retract the inner rod 2 upwards; it first passes through the tapered elastic hole 13, which then tightens, returning the smaller end to its natural diameter. Continue rotating and retracting the inner rod 2 upwards. As the mop head 3 passes through the tapered elastic hole 13, it experiences a combined effect of continuous tightening pressure and rotational torsion, completing the wringing process. After wringing, the mop head 3 is fully retracted into the cleaning chamber. To mop, simply push the mop head 3 out of the outer rod 1.

[0059] In this embodiment, the opening is an elastically constrained opening that is normally open in its natural state. When the mop head retracts through the opening, it is subjected to a combination of continuous tightening squeezing force and rotational torsion force to complete the squeezing and wringing. Example 5: Normally Closed Elastic Hole Type

[0060] Reference Figure 1 , Figure 5 A and Figure 5 C. The difference between this embodiment and Embodiment 4 is that the lower end of the outer rod 1 is provided with a normally closed elastic hole 14, which elastically tightens and closes in its natural state. The opening communicates with the cleaning chamber and is an elastically constrained opening. The remaining structure, materials, and operation methods are the same as in Embodiment 4.

[0061] In this embodiment, the opening is an elastically constrained opening that is normally closed in its natural state. When the mop head retracts through the opening, it is subjected to a combined effect of continuous tightening pressure and rotational torsion force to complete the squeezing and wringing. The main difference between this embodiment and Embodiment 4 is that the opening is normally closed in its natural state, and automatically tightens and returns to its closed state after the mop head passes through. During retraction, the tightening gripping force of the elastic hole performs a secondary squeezing on the mop head. Example 6: Double-door flexible door

[0062] Reference Figure 1 and Figure 6 In this embodiment, the lower end of the outer rod 1 is provided with two double-leaf elastic doors 15, which open and close inwards in their natural state. The openings are connected to the cleaning chamber and are elastically constrained openings.

[0063] A preset gap is left between the two double-leaf flexible doors 15, allowing a small amount of liquid to seep out during cleaning, so that users can judge whether the mop head is clean by observing the turbidity of the seeping liquid.

[0064] It also includes an inner rod 2, which passes inside the outer rod 1. The mop head 3 is connected to the lower end of the inner rod 2, which is tapered to facilitate guidance in and out and prevent jamming during pull-back. Rollers 16 can be installed on the edges of the two double-leaf resilient doors 15 to reduce friction and make the mop head move in and out more smoothly. The rollers 16 can be installed on the edges of one or both doors.

[0065] The inner wall of the outer rod 1 is provided with a stabilizing connection structure 23, which is sleeved on the inner rod 2 to restrict the radial sway of the outer rod 1 relative to the inner rod 2. The inner rod 2 is also provided with a limiting structure 9 to prevent it from detaching from the outer rod 1 when retracting.

[0066] During cleaning, the mop head 3 is retracted into the cleaning chamber, and the double-door flexible door 15 closes naturally. The mop is placed upright on the ground, and its own weight, along with the ground's reaction force, prevents the double-door flexible door 15 from opening. Cleaning solution is injected through the water inlet 5, and the inner rod 2 is pushed and pulled to move the mop head 3 up and down for rinsing.

[0067] When wringing, the mop head 3 pushes open the double-door flexible door 15 outwards with slight resistance. When mopping, the mop head 3 can be extended from the outer rod 1 to mop. When the mop head 3 is retracted, it is pulled inwards, and the double-door flexible door 15 is driven to clamp inwards, generating a counterforce that clamps the mop head 3 to achieve scraping, squeezing, and wringing.

[0068] In this embodiment, the opening is an elastically constrained opening that closes inward in its natural state. When the mop head retracts the opening, it is subjected to clamping and squeezing force to complete the squeezing and wringing. Example 7: Magnetic drive type without inner rod

[0069] Reference Figure 7 In this embodiment, the outer rod 1 is a hollow cavity, and its internal space constitutes a cleaning chamber. There is no inner rod; the mop head 3 is driven to retract or extend from the outer rod 1 cavity via magnetic attraction.

[0070] The lower end of the outer rod 1 is equipped with a ground-fixed base 4. A detachable, sealed connection structure, either threaded or snap-fit, is provided between the base 4 and the lower end of the outer rod 1. When the lower end of the outer rod 1 is connected to the base 4, the opening at the lower end of the outer rod 1 is closed, and the cavity of the outer rod 1 and the base 4 together form the cleaning chamber. When the lower end of the outer rod 1 is separated from the base 4, the opening is open, the mop head 3 can extend, and dirty water can be drained.

[0071] The lower surface of the base 4 can be equipped with an anti-slip pad, suction cup, or snap-fit ​​structure to fit with the floor drain, so as to fix it to the ground.

[0072] The outer rod 1 is provided with a fixed axial sliding track, on which an external magnetic block assembly 17 is fitted. The external magnetic block assembly 17 consists of a permanent magnet and a plastic shell encasing the permanent magnet. One side of the plastic shell is tightly fitted to the outer surface of the outer rod 1, allowing it to slide up and down along the sliding track. The surface of the sliding track is provided with guide grooves to ensure that the external magnetic block assembly 17 slides smoothly along the sliding track and maintains stable magnetic coupling when the mop head 3 rotates.

[0073] The outer rod 1 has a fixed axial sliding track at a corresponding position inside. An internal magnetic block assembly 18 is fitted onto the sliding track. The internal magnetic block assembly 18 consists of a permanent magnet and a plastic shell encasing the permanent magnet. The internal magnetic block assembly 18 is magnetically attracted and linked to the external magnetic block assembly 17. When the external magnetic block assembly 17 slides up and down, the internal magnetic block assembly 18 moves synchronously. The sliding track inside the outer rod 1 has a guide rail, and the internal magnetic block assembly 18 slides in cooperation with the guide rail, realizing axial sliding while limiting radial displacement, ensuring stable operation when the motor 19 drives the mop head 3 to rotate.

[0074] The lower end of the internal magnetic block assembly 18 is fixedly connected to the micro motor 19 via a stable connection structure 23. The output shaft of the motor 19 extends downward, and the mop head 3 is directly mounted on the output shaft of the motor 19.

[0075] A sealing partition 20 is provided at the upper part of the inner side of the outer rod 1, which completely isolates it from the cleaning chamber. A lithium battery 21 and a control circuit board are housed within the sealing partition 20. A waterproof switch 22 is provided at the top or side of the outer rod 1. The switch 22 uses a silicone-sealed button, and an O-ring seal is provided around the button. The motor 19 is connected to the circuit board within the sealing partition 20 via a waterproof wire 24.

[0076] The lower end of the outer rod 1 is provided with a multi-functional processing module 25, which is used to perform auxiliary processing on the mop head 3.

[0077] The multifunctional processing module 25 can be at least one of an ultrasonic transducer, a vibration motor, an ultraviolet disinfection module, an ion sterilization module, or an automatic detergent dispensing device. The automatic detergent dispensing device injects detergent from the detergent storage chamber into the cleaning chamber via a micro-pump.

[0078] All electronic components in the multifunctional processing module 25 can be waterproofed and sealed, for example, by potting, setting up a waterproof cavity, or using a waterproof coating. They are connected to the circuit board through waterproof wires to ensure normal operation in the humid environment of the cleaning chamber.

[0079] During cleaning, slide the outer magnetic block assembly 17 upwards. The inner magnetic block assembly 18, through magnetic force, drives the motor 19 and mop head 3 into the cleaning chamber. Connect the lower end of the outer rod 1 to the base 4 to close the opening. Inject cleaning fluid through the water inlet 5. Turn on the switch 22. The motor 19 drives the mop head 3 to rotate, completing the electric rotation and rinsing within the cleaning chamber. During the cleaning process, the multi-functional processing module 25 can be activated to perform ultrasonic cleaning, vibration cleaning, or disinfection and sterilization on the mop head 3.

[0080] During the spin-drying process, remove the outer rod 1 from the base 4, drain the dirty water, and then place the outer rod 1 naturally downwards on the ground or fix it back to the base 4, ensuring that the mop head 3 remains within the cleaning chamber. Turn on the switch 22, and the motor 19 will drive the mop head 3 to rotate at high speed for centrifugal spin-drying. After spin-drying, the multi-functional processing module 25 can be activated to provide auxiliary processing for the mop head 3. Slide the outer magnetic block assembly 17 downwards, and the inner magnetic block assembly 18 will drive the motor 19 and the mop head 3 to extend out of the outer rod 1 cavity, allowing you to mop the floor.

[0081] It is understood that, based on the above-described structural foundation of Embodiment Seven, the driving mechanism is not limited to magnetic attraction linkage. For example, the external magnetic block assembly 17 and the internal magnetic block assembly 18 can be replaced with a connecting rod linkage mechanism. Specifically, a groove is opened on the outer rod 1 corresponding to the original magnetic attraction slide, and a push button or slider is set, which is directly connected to the mop head 3 inside through the connecting rod. The user can manually slide the push button to directly drive the mop head 3 to retract or extend from the cleaning chamber through the connecting rod, realizing manual sliding groove push-pull drive. Similarly, a push-type drive mechanism can also be used, which realizes the operation of pushing out the mop head 3 once and pushing back the mop head 3 again through the cooperation of a ratchet and a return spring. Simple replacements of the above driving methods should be understood to fall within the protection scope of this invention.

[0082] In this embodiment, the opening is an openable and closable opening, which is achieved through a detachable sealing connection structure. The driving mechanism is a magnetic drive mechanism, the cleaning method is electric rotary cleaning, and the dehydration method is electric centrifugal drying. Example 8: Fixed Opening Snap-in Type

[0083] Reference Figure 1 and Figure 8 The difference between this embodiment and Embodiment 3 is that the lower end of the outer rod 1 is provided with a fixed opening 26. The diameter of the fixed opening 26 is fixed and inelastic. The diameter is larger than the maximum outer diameter of the mop head 3, allowing the mop head 3 to move freely in and out. The fixed opening 26 is connected to the cleaning chamber and is an openable and closable opening.

[0084] The mop head 3 has a locking member 11 at its bottom for retracting the mop cloth. The locking member 11 is rotatably connected to the mop head 3; when wrung out, the mop head 3 can rotate relative to the locking member 11, which maintains a tight seal with the fixed opening 26. The locking member 11 has an internal shape that matches the fixed opening 26 but is slightly smaller, allowing it to engage with and be constrained by the fixed opening 26. The locking member 11 is slightly larger than the fixed opening 26 externally to prevent it from fully entering. The locking member 11 may be made of a soft-surface material to reduce friction with the floor during mopping.

[0085] It also includes an inner rod 2, which passes through the outer rod 1. The upper part of the mop head 3 is connected to the lower end of the inner rod 2.

[0086] During cleaning, the mop head 3 is retracted into the cleaning chamber, and the locking piece 11 is engaged with the fixing opening 26. Cleaning fluid is injected through the water inlet 5, and the inner rod 2 is pushed and pulled to move the mop head 3 up and down for rinsing.

[0087] When wringing, the locking part 11 remains locked into the fixed opening 26. Rotating the inner rod 2 causes the mop head 3 to be subjected to rotational torsional force, completing the wringing and dehydration process.

[0088] After the dehydration is complete, apply a little force to push the mop head 3 downwards, the locking part 11 disengages from the fixed opening 26, and the mop head 3 extends out of the fixed opening 26, ready to mop the floor.

[0089] In this embodiment, the opening is an openable and closable opening, which is opened and closed by the cooperation of the snap-fit ​​part 11 and the fixed opening 26. The opening is closed when the snap-fit ​​part 11 is engaged with the fixed opening 26, and the opening is open when the snap-fit ​​part 11 is disengaged from the fixed opening 26. The mop head 3 enters and exits through the fixed opening 26. General Instructions

[0090] In the above eight embodiments, the openings in embodiments one to three, seven, and eight are openable and closable openings, while the openings in embodiments four to six are elastically constrained openings.
