Description

Technical Field

[0001] The invention relates to a cleaning tool, in particular to a self-squeezing water-producing foamed cotton mop with a completely new water-squeezing structure. The foamed cotton can be a rubber cotton head, a sponge head or the like. Background Art

[0002] There are three ways to squeeze water from foam mops on the market: the first is the hand-pull squeeze, such as the Chinese utility model patent "Cotton mop" with patent number ZL03231227.X (publication number CN 2626415Y), the Chinese utility model patent "insertion-type squeezing water foam mop" with patent number ZL 200920121093.8 (publication number CN201409887Y), and the Chinese utility model patent "insertion-type squeezing water foam mop" with patent number ZL The Chinese utility model patent "A collodion mop" with patent number 200920075021.4 (publication number CN201453183U) and the Chinese invention patent "Movable multifunctional collodion mop" with patent number ZL201110102067.2 (publication number CN102138771A) both disclose such a collodion mop; the second type is a mop head flipping integral water squeezing type, such as a series of patents applied for by the applicant, including a mop rod and foam cotton, the foam cotton is movably connected to the lower end of the mop rod, the mop rod is provided with a squeezing device that can slide up and down relative to the mop rod, the foam cotton can be rotated to make its length direction basically parallel to the mop rod and aligned with the squeezing device, when squeezing water, the squeezing device slides up and down along the length direction of the foam cotton and squeezes the bottom surface of the foam cotton to achieve squeezing water, and the foam cotton is completely separated from the squeezing device when mopping the floor; the third type is a folding water squeezing type.

[0003] Each water squeezing method has its own disadvantages. In the first water squeezing structure, the overall lateral length of the water squeezing part is very long, which is relatively bulky. During the squeezing process, the contact area between the water squeezing rod and the rubber cotton head is very large, and the friction during squeezing is greatly increased. In addition, there are generally multiple rows of water squeezing rods on the front or rear side, which consumes a lot of materials and the squeezing frame cost is high. Due to the particularity of the squeezing frame structure, the rubber cotton head must be fixedly connected to the mop rod, 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. In the second water squeezing structure, the foam cotton is not easy to separate from the squeezing port in the squeezing frame after it hardens. In the third water squeezing structure, because there is a fold in the middle of the mop head, the mop head is kept in an unfolded mopping state only by an elastic member, but the flatness of the unfolded mop head will always be defective. The folded mop head will never be too flat when mopping the floor, resulting in part of the floor not being cleaned (such as the arched position in the middle), and the cleaning effect is poor.

[0004] In summary, the existing self-squeezing collodion mop can be further improved. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a self-squeezing foam mop which changes the water squeezing method of the traditional rubber cotton mop in view of the above-mentioned existing technical status, and the mop can better avoid the defects of the existing foam mop.

[0006] The technical solution adopted by the present invention to solve the above technical problems is: a self-squeezing foam mop, including a mop rod and a mop head with foam, characterized in that: the mop head includes a base plate movably connected to the lower end of the mop rod, the foam is installed on the bottom surface of the base plate and can shrink or expand relative to the base plate along the length direction, and the foam can be driven by a driving structure to shrink relative to the base plate along the length direction. When squeezing water, the driving structure drives the foam to shrink along the length direction of the base plate to achieve squeezing water. After squeezing water, the foam is reset and expanded along the length direction under the action of its own elastic force or the driving structure.

[0007] Further improvement, the bottom of the above-mentioned base plate is provided with a slider that can slide along the length direction of the base plate, the foam is installed on the slider, the driving structure is a pushing device that is provided on the mop rod and can slide along the mop rod, the mop head can be rotated to be substantially parallel to the mop rod in its length direction and aligned with the pushing device, when squeezing water, the pushing device slides along the mop rod to push the foam or the slider to contract along the length direction of the base plate to squeeze water, and when squeezing water is finished, the pushing device moves up and resets, and the foam is reset and expanded along the length direction under the action of its own elastic force or external force. The pushing device is used as the driving structure, and the pushing device does not need a complex transmission structure, and has the advantages of simple structure and convenient operation.

[0008] Preferably, a fixing block is fixed on one end of the substrate, one end of the foam is fixed on the fixing block, and the other end of the foam is fixed on the slider. The foam installation structure is the simplest.

[0009] Of course, there can be two sliders, and the two ends of the foam are fixed on one of the sliders respectively. A synchronous transmission structure is provided between the two sliders to ensure that the two sliders can slide synchronously toward or in the opposite direction. When the sliders slide the same distance, the deformation of the foam shrinkage is doubled, and the water squeezing efficiency is higher. The synchronous transmission structure can adopt a gear rack transmission structure, that is, a rack part is provided on the two sliders, and a transmission gear that is synchronously meshed with the two rack parts is provided in the base plate.

[0010] In order to ensure smooth sliding of the foam and better support for the foam, a further improvement is made in which a plurality of auxiliary sliders are provided in the base plate, the auxiliary sliders are located between the fixed block and the slider, and each of the auxiliary sliders is fixed on the foam; a guide rail arranged along the length direction is provided in the base plate, and the slider and the auxiliary slider are arranged on the guide rail. With the support of the slider, the fixed block and the plurality of auxiliary sliders, the foam is not easily deformed during the mopping process.

[0011] As a further improvement, the slider has a baffle portion extending downward, the baffle portion is located at the outer end surface of the foam, and when the mop head is rotated to a state where its length direction is substantially parallel to the mop rod, the baffle portion faces the pushing device and can be pushed by the pushing device. The pushing component does not directly push the foam to avoid damaging the foam, and can exert force on the middle of the outer end surface of the foam, making pushing more labor-saving.

[0012] As a further improvement, an unlockable locking structure is provided between the slider and the base plate. In the mopping state, the locking structure can lock the foam in a position in which it is unfolded along the length direction, so that the slider cannot slide along the length direction of the base plate; in the squeezing state, the locking structure is unlocked, so that the slider can be driven by the driving structure. When mopping, the foam is locked and is not easy to slide along the length direction, making mopping smoother. When squeezing, the locking structure is released, and the foam can slide along the length direction, so that squeezing can be performed.

[0013] Preferably, when the mop head is rotated to a position where its length direction is substantially parallel to the mop rod, the locking structure is triggered by the mop rod to be unlocked. No additional unlocking device is required, or additional unlocking operation is performed, which is more convenient to use.

[0014] Preferably, the locking structure comprises a locking key provided on the substrate and maintained by a spring to be exposed from the top surface of the substrate, a locking portion having a transverse portion below the locking key, a dovetail groove matching the slider and the locking portion, and the locking portion is inserted downward into the dovetail groove; when the locking key is in an upward position, the transverse portion of the locking portion is disengaged from the dovetail groove upward, and the slider cannot slide relative to the locking key; after the locking key is pressed down by the mop rod, the transverse portion of the locking portion is located in the dovetail groove, so that the slider can slide relative to the locking key. Of course, other locking structures with similar functions can be designed based on the aforementioned unlocking method.

[0015] Preferably, the pushing device comprises a pushing handle disposed on the mop rod and capable of sliding up and down, the lower end of the pushing handle has a pushing portion, a space for the substrate to pass through is provided between the pushing portion and the mop rod, a positioning structure is provided between the pushing handle and the mop rod, the positioning structure can position the pushing handle in an upward position, and the pushing handle can slide up and down along the mop rod after the positioning structure is released. The pushing device has a simple structure, is easy to operate, and has a low cost.

[0016] Compared with the prior art, the advantages of the present invention are as follows: the foam in the foam mop is installed on the bottom surface of the base plate and can shrink or expand relative to the base plate along the length direction; the mop head can be movably connected to the lower end of the mop rod; the mop head can be deflected during mopping, and the operation is more comfortable and reasonable; when squeezing water, the foam is driven by the driving structure to shrink along the length direction of the base plate to achieve squeezing water, which is completely different from the technical method of the existing foam mop, the squeezing water structure is simple and the entire squeezing water stroke is short, and the mop head does not need to pass through the squeezing water outlet of the squeezing frame, thereby avoiding the defect that the foam is not easy to separate from the squeezing outlet in the squeezing frame after hardening; the mop head does not need to be folded in half, thereby avoiding the defect that the folded foam mop does not mop the floor cleanly.

[0026] The present invention is further described in detail below with reference to the accompanying drawings.

[0027] like Figures 1 to 7 Shown is a preferred embodiment of the present invention.

[0028] A self-squeezing foam mop comprises a mop rod 1 and a mop head 3 with foam 4. The foam can be collodion, sponge or the like.

[0029] The mop head 3 includes a base plate 31 movably connected to the lower end of the mop rod 1. The foam 4 is installed on the bottom surface of the base plate 31 and can shrink or expand relative to the base plate 31 along the length direction. The foam 4 can be driven by the driving structure to shrink relative to the base plate 31 along the length direction. When squeezing water, the driving structure drives the foam 4 to shrink along the length direction of the base plate 31 to squeeze water. After squeezing water, the foam 4 is restored and expanded along the length direction under the action of its own elastic force or the driving structure.

[0030] A slider 32 capable of sliding along the length direction of the substrate 31 is provided at the bottom of the substrate 31, and the foam 4 is mounted on the slider 32. The driving structure is a pushing device 2 provided on the mop rod 1 and capable of sliding along the mop rod 1. The mop head 3 can be rotated to be substantially parallel to the mop rod 1 in its length direction L and aligned with the pushing device 2. When squeezing water, the pushing device 2 slides along the mop rod 1 to push the foam 4 or the slider 32 to contract along the length direction of the substrate 31 to squeeze water. After squeezing water, the pushing device 2 moves up and resets, and the foam 4 resets and expands along the length direction under the action of its own elastic force or external force (possibly a spring).

[0031] In this embodiment, a fixing block 33 is fixed on one end of the base plate 31, one end of the foam 4 is fixed on the fixing block 33, and the other end of the foam 4 is fixed on the slider 32. A plurality of auxiliary sliders 34 are also provided in the base plate 31, and the auxiliary sliders 34 are located between the fixing block 33 and the slider 32, and each auxiliary slider 34 is fixed on the foam 4; a guide rail 35 arranged along the length direction is provided in the base plate 31, and the slider 32 and the auxiliary slider 34 are arranged on the guide rail 35. The slider 32 has a baffle portion 321 extending downward, and the baffle portion 321 is located on the outer end surface of the foam 4, and when the mop head 3 is rotated to a state where its length direction L is substantially parallel to the mop rod 1, the baffle portion 321 faces the pushing device 2 and can be pushed by the pushing device 2.

[0032] Of course, there can also be two sliders 32, and the two ends of the foam 4 are respectively fixed on one of the sliders 32. A synchronous transmission structure is provided between the two sliders 32 to ensure that the two sliders 32 can slide synchronously toward or in the opposite direction, which is not shown in the drawings.

[0033] An unlockable locking structure 5 is provided between the slider 32 and the base plate 31. In the mopping state, the locking structure 5 can lock the foam 4 in a position in which it is unfolded in the length direction, so that the slider 32 cannot slide in the length direction of the base plate 31. In the squeezing state, the locking structure 5 is unlocked, so that the slider 32 can be driven by the driving structure. When the mop head 3 is rotated to a position in which its length direction L is substantially parallel to the mop rod 1, the locking structure 5 is triggered by the mop rod 1 and unlocked.

[0034] The locking structure 5 includes a locking key 51 disposed on the base plate 31 and maintained by a spring 52 to be exposed from the top surface of the base plate 31, a locking portion 511 having a transverse portion 512 below the locking key 51, a dovetail groove 322 matching the locking portion 511 of the slider 32, and the locking portion 511 being inserted downward into the dovetail groove 322; when the locking key 51 is in an upward position, the transverse portion 512 of the locking portion 511 is disengaged from the dovetail groove 322 upward, and the slider 32 cannot slide relative to the locking key 51; after the locking key 51 is pressed down by the mop rod 1, the transverse portion 512 of the locking portion 511 is located in the dovetail groove 322, so that the slider 32 can slide relative to the locking key 51.

[0035] The pushing device 2 includes a pushing handle 21 which is arranged on the mop rod 1 and can slide up and down. The lower end of the pushing handle 21 has a pushing portion 22. There is a space P between the pushing portion 22 and the mop rod 1 for the substrate 31 to pass through. A positioning structure is provided between the pushing handle 21 and the mop rod 1. The positioning structure can position the pushing handle 21 in an upward position. After the positioning structure is released, the pushing handle 3 can slide up and down along the mop rod 1.

[0036] As shown in the figure, the pushing part can be an annular frame, and the inner space of the frame is for the substrate to pass through. As shown in the figure, the pushing part can also be a push rod, and there is a distance between the push rod and the mop rod to form a space P.

[0037] The positioning structure in this embodiment includes a positioning block 7 fixed on the mop rod 1 and an elastic slot 6 provided in the push handle 21. When the push handle 21 is forced to move upward to the highest position, the positioning block 7 is snapped into the elastic slot 6 to complete the positioning. When the water squeezing rack 3 is forced to move downward, the positioning block 77 is disengaged from the elastic slot 6 to complete the unlocking.

[0038] The up-down direction in this embodiment refers to the length direction along the mop rod 1 .

[0039] The working principle and process of this embodiment are as follows:

[0040] Water squeezing operation: first, turn the mop head 3 to be basically parallel to the mop rod 1, with the end surface of the foam 4 facing the pushing portion 22 of the pushing device 2, hold the pushing handle 21 with one hand, hold the mop rod 1 with the other hand, push the pushing handle 21 downward relative to the mop rod 1, and the pushing portion 22 pushes the foam 4 to shrink along the length direction of the base plate 31 to achieve water squeezing, then push the handle 21 upward relative to the mop rod 1, and the pushing portion 22 leaves the foam 4. The foam 4 is reset and expanded along the length direction under the action of its own elastic force or external force (possibly a spring), and water squeezing is achieved in this reciprocating manner.

[0041] Mopping operation: hold the squeeze mop 3 with one hand and the mop rod 1 with the other hand, pull up the push handle 21 to move it to a high position relative to the mop rod 1, and the push part 22 leaves the foam 4. At this time, the push handle 21 is in a high position, and the positioning block 7 is inserted into the elastic slot 6 to complete the positioning. In this way, the push handle 21 is fixed relative to the mop rod 1, and the mop head 3 is flipped to a state basically vertical to the mop rod 1 to start mopping.

[0042] like Figure 8 , 9 FIG. 2 is a second embodiment of the present invention.

[0043] The difference between this embodiment and the preferred embodiment is that the pushing portion 22 of the pushing device 2 is different.

[0044] Figure 7 and Figure 8 The pushing member 22 in FIG.

[0045] Although the preferred embodiments of the present invention are described in detail above, it should be clearly understood that the present invention can be modified and varied by a person skilled in the art. For example, the following driving block can also be a way to drive the caliper seat to move forward and backward to achieve water squeezing. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
