Description

Technical Field

[0001] The invention belongs to the technical field of cleaning products, and in particular relates to a self-lifting mop cleaning tool. Background Art

[0002] Among the existing mop and mop bucket kit tools, there is a type of mop bucket that can be coaxially lifted and lowered to achieve cleaning and dehydration, which is accomplished by lifting the mop. For example, Chinese utility model patent No. ZL201821379338.2 discloses a "cleaning mop self-lifting cleaning tool with clean and dirty water separation cleaning bucket", which is equipped with a lifting device, and the mop is manually lifted to achieve switching between high and low positions; another example is Chinese utility model patent No. ZL201820024081.2, which discloses a "mop self-lifting cleaning tool", which is also achieved by manually lifting the lifting device to achieve switching between high and low positions;

[0003] This type of mop bucket switches between cleaning and dehydration states by changing the height of the mop head. When switching states, the mop head needs to stop rotating and then pull the mop upward, which is relatively cumbersome. Summary of the Invention

[0004] The main technical problem solved by the present invention is to provide a cleaning tool that controls the lifting and lowering of the mop head by adjusting the rotation speed of the mop head. The mop can automatically switch between cleaning and dehydration operations in the mop bucket without the need for lifting or other operations. The switching is seamless and very convenient.

[0005] In order to solve the above technical problems, a technical solution adopted by the present invention is as follows:

[0006] A self-lifting mop cleaning tool comprises a mop and a mop bucket, wherein the mop comprises a mop head and a mop rod, and the mop bucket is provided with a support column for supporting the mop, wherein the mop head is supported on the support column for cleaning and / or dehydration;

When the driving member is located at the end with the larger gap, the lifting plate is located in a low position. When the mop head rotates, the driving member moves toward the periphery under the action of centrifugal force and drives the gap to increase, thereby raising the lifting plate to a high position.

[0009] Furthermore, a guide groove for guiding the movement direction of the driving member is provided in the gap, and the guide groove is provided on the lifting plate or the fixed plate. The guide groove is inclined to form a structure in which the gap gradually decreases from the center of the lifting plate to the periphery.

[0010] Furthermore, the driving member is in the shape of a sphere or a block, and is provided with an elastic driving member that drives it to move toward the end with the larger gap.

[0011] Furthermore, an elastic member is provided between the fixed plate and the lifting plate, and the elastic member drives the gap to remain in a small state so that the lifting plate is located at a low position.

[0015] Furthermore, the through hole has a hole wall extending axially, the hole wall is in contact with the side wall of the step, and both the hole wall and the side wall are provided with through-holes, and the driving member is provided with a positioning column that can be inserted into the through-holes. When the driving member is located at the end with the larger gap, the positioning column is simultaneously inserted into the two through-holes to lock the lifting plate.

[0016] Furthermore, the mop bucket is provided with a clean water area, above which is a working area, a water pump for pumping clean water to the working area is provided in the clean water area, a driving part for driving the water pump extends from the clean water area to the working area, and the upper end of the driving part is the support column;

[0017] The mop can be supported by the driving part to rotate, and a clamping part is provided between the lifting plate and the driving part to prevent the two from rotating circumferentially. When the lifting plate is in a low position, the clamping part is engaged to drive the water pump to work, and the water pump pumps out clean water and sprays it on the mop; when the lifting plate is in a high position, the clamping part is disengaged, the water pump stops working, and the mop continues to rotate to dehydrate.

[0018] Furthermore, the mop bucket is further provided with a sewage area, which is not connected to the clean water area but is connected to the working area, and the sewage generated by the mop operating in the working area can flow into the sewage area.

[0019] Furthermore, the water pump includes a pump casing and an impeller, the impeller is sleeved on a rotating shaft fixed to the mop bucket and is capable of rotating, the impeller has a drive shaft coaxially arranged therewith, the drive shaft passes through the clean water area to form the drive part, and the mop head has a positioning hole for inserting the drive shaft.

[0020] Furthermore, the water pump includes a piston pump, which is connected to the driving part and driven by the driving part.

[0021] Furthermore, the piston rod of the piston pump is hinged to the eccentric wheel via a connecting rod, and the eccentric wheel is connected to the driving part via a gear mechanism.

[0022] Furthermore, the engaging portion is a ridge provided on the outer periphery of the driving portion and a groove provided on the inner side wall of the positioning hole, and the ridge and the groove can engage with each other to limit the circumferential rotation of the driving shaft and the lifting plate.

[0023] Furthermore, the mop bucket includes a first barrel body and a second barrel body stacked up and down, the first barrel body located at the bottom is the clean water area, the second barrel body located at the top is the working area, and the outer periphery of the second barrel body extends downward with a accommodating cavity, which is the sewage area.

[0024] Furthermore, the mop bucket includes a bucket body having a partition plate for dividing its inner cavity into the clean water area and the dirty water area, and a cover plate is provided above the clean water area, and the working area is above the cover plate.

[0025] Furthermore, a cleaning member for cleaning the mop is provided in the mop bucket. When the mop is located at a low position for cleaning, the cleaning member contacts the wiping material of the mop to clean it.

[0026] Furthermore, the cleaning element includes a cleaning scraper, a cleaning brush or a roller rotatable along its axis.

[0027] The rotary mop of the present invention can move toward the periphery at a certain rotation speed through the centrifugal force of the driving member to lift the lifting plate, thereby realizing the lifting and lowering operation of the mop head. The automatic lifting and lowering operation does not require manual lifting of the mop, which is very convenient.

[0028] The self-lifting mop cleaning tool of the present invention does not require manual lifting when switching between cleaning and dehydration operations, thereby achieving seamless switching between cleaning and dehydration. Furthermore, there is no need to wait for the mop head to stop rotating when switching, thus saving time and effort.

[0029] When cleaning, water is sprayed through the water pump, which has a good cleaning effect. When dehydrating, the lifting plate can be disengaged from the driving water pump as it rises. After the water spraying stops, the mop continues to rotate to dehydrate. The entire cleaning and dehydration operations are seamlessly switched and completed in one go.

[0064] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention. Example 1

[0065] A rotary mop, such as Figure 1 As shown: the mop 1 comprises a mop head 2 and a mop rod 3, wherein the mop head can rotate to achieve cleaning and / or dehydration, and the rotation of the mop head is driven by hand pressing the mop rod or a motor;

[0066] like Figures 2 to 4 As shown in the figure: the mop head includes a fixed plate 21 and a lifting plate 22, the fixed plate is connected to the mop rod and can rotate, the lifting plate is connected to the fixed plate, the lifting plate can move up and down relative to the fixed plate, and the lifting plate can rotate with the fixed plate, the wiping object is fixedly connected to the lifting plate. It should be noted that the up and down movement of the lifting plate mentioned here is relative to the state when the mop head is normally located at the bottom.

[0067] There is a gap 4 between the lifting plate and the fixed plate, and the gap gradually decreases from the center of the lifting plate to the periphery. A driving member 5 is provided in the gap. When the driving member is located at the end with the larger gap, the lifting plate is located in a low position. When the mop head rotates, the driving member moves toward the periphery under the action of centrifugal force and drives the gap to increase, thereby raising the lifting plate to a high position, thereby realizing automatic lifting of the lifting plate with the wiping object, so that the high-position action and the low-position operation can be completed without manual lifting action.

[0068] During implementation, the weight of the driving member can be adjusted to achieve the following: at a certain rotation speed, the driving member can open the gap. This is easy to understand. The specific weight of the driving member is not easy to quantify here, because the weight also needs to be tested and adjusted based on the weight of the lifting plate and the actual accuracy (sliding smoothness) that the product can achieve.

[0069] A guide groove 41 for guiding the movement direction of the driving member is provided in the gap. The guide groove is provided on the lifting plate or the fixed plate. The guide groove is inclined to form a structure in which the gap gradually decreases from the center of the lifting plate to the periphery.

[0070] This embodiment Figure 2 As shown: the guide groove is provided on the fixed plate, and the movement direction of the driving member is guided by the guide groove, so that the driving member can move along the optimal path to complete the action of opening the lifting plate. Preferably, at least two guide grooves are provided and are evenly distributed along the rotation axis of the mop head;

[0071] In this embodiment, there are two guide grooves (that is, two driving members are provided), and the provision of at least two can achieve the balance of the mop head during rotation. Moreover, after proofing tests, the two guide grooves (driving members) can well complete the action of supporting the lifting plate, and have no effect on the balance and rotation smoothness of the mop head during rotation.

[0072] Preferably, the driving member is a sphere, and the spherical structure can reduce friction when moving, so that the driving member can move smoothly.

[0073] In this embodiment, the sphere is made of metal. The metal sphere has a certain weight, and the centrifugal force of the rotation can easily make it move toward the periphery, thereby expanding the gap.

[0074] like Figure 3 and Figure 4 As shown: an elastic member 23 is provided between the fixed plate and the lifting plate, and the elastic member drives the gap to maintain a small state so that the lifting plate is located in a low position, that is, in normal state, the lifting plate is located in a low position, and the elastic member can also assist the lifting plate in resetting after being located in a high position. In this embodiment, the elastic member is a coil spring.

[0075] The mop head of the present invention can be rotated by manually pressing and rotating the mop rod, or by a motor, both of which are prior arts and thus need not be described in detail.

[0076] The specific structures of the fixed plate and the lifting plate are as follows Figure 5 Shown and Figure 6 The lifting plate 22 has a cavity 221, the fixed plate is located in the cavity, and the fixed plate 21 has a boss 211 extending from the cavity, and the boss is movably connected to the mop rod.

[0077] In this embodiment, the mop rod is connected to the boss via a cross shaft so that the mop head can achieve universal rotation; the lifting plate is further provided with a panel 24 for mounting a wiping object, and the panel is detachably connected to the lifting plate.

[0078] A cleaning tool such as Figures 7 to 9 As shown: It includes a mop 1 and a mop bucket 6. The mop adopts the above-mentioned rotary mop. The mop bucket is provided with a clean water area 61. Above the clean water area is a working area 62. A water pump 7 is provided in the clean water area to pump clean water to the working area. A driving part 71 that drives the water pump to work passes through the clean water area to the working area. At the same time, the driving part also constitutes a supporting part that supports the work of the mop.

[0079] The protruding driving part also constitutes a support column 66 for supporting the operation of the mop. The mop can be supported by the driving part to rotate, and a clamping part 72 is provided between the lifting plate and the driving part to prevent the two from rotating circumferentially. When the lifting plate is in a low position, the clamping part is engaged to drive the water pump to work, and the water pump draws out clean water and sprays it on the mop; when the lifting plate is in a high position, the clamping part is disengaged, the water pump stops working, and the mop continues to rotate to dehydrate.

[0080] The cleaning tool of the present invention does not require manual lifting when switching between cleaning and dehydration operations. The operation of raising and lowering the mop head is completed by adjusting the rotation speed of the mop head to achieve seamless switching between cleaning and dehydration. There is no need to wait for the mop head to stop rotating when switching, which saves time and effort. Water is sprayed by the water pump during cleaning, and the cleaning effect is good.

[0081] The mop bucket of the present invention also has the function of separating clean and dirty water. The mop bucket is further provided with a sewage area 63, which is not connected to the clean water area but is connected to the working area. The sewage generated by the mop operating in the working area can flow into the sewage area.

[0082] In this embodiment, the mop bucket includes a first barrel body 64 and a second barrel body 65 stacked up and down. The first barrel body located at the bottom is the clean water area, and the second barrel body located at the top is the working area. The clean water area is also provided with a water inlet 611.

[0083] A accommodating chamber 651 extends downward from the outer periphery of the second barrel body, and the accommodating chamber is the sewage area. The sewage area formed by the downwardly extending accommodating chamber is lower than the working area, so the wastewater generated in the working area can automatically flow into the sewage area under the action of gravity.

[0084] like Figure 9 and Figure 10 As shown: a cleaning member for cleaning the wiping material of the mop is provided in the working area. In the embodiment of this city, the cleaning member is a horizontally arranged roller 8, which can rotate along its axis and has a plurality of sharp teeth 81 on its outer periphery;

[0085] When the mop is operated in the working area, the roller can form a certain degree of extrusion with the mop's wipes, and the sharp teeth on its surface can help clean the garbage on the surface of the wipes. In this embodiment, the sharp teeth are truncated cone-shaped. Of course, the sharp teeth can also be set to be conical or cylindrical.

[0086] like Figure 8 and Figure 11 As shown: the water pump includes a pump housing 78 and an impeller 73. The impeller is sleeved on a rotating shaft 74 fixed to the mop bucket and is rotatable. The impeller has a drive shaft 731 coaxially arranged therewith. The drive shaft passes through the clean water area to form the drive part. The mop head has a positioning hole 732 for inserting the drive shaft.

[0087] This embodiment Figure 11 As shown: the impeller 73 includes a first blade and a second blade, the second blade is located below the first blade and is coaxially arranged, the upper end of the second blade extends upward to cover the first blade, and the protruding part constitutes the pump casing, and the water outlet speed of the second blade is lower than the water outlet speed of the first blade.

[0088] Moreover, in this embodiment, the first blade and the second blade rotate synchronously and are both axial flow blades, but the blade angles of the two are different, that is, different water outlet speeds are achieved through different blade angles. The blade angle refers to the water outlet angle of the blade, that is, the angle between the blade and the end face of its wheel body. The different water outlet angles of the blade can provide different water pressures to achieve different water outlet speeds.

[0089] In this embodiment, the second blade is located at the bottom and is located at the water inlet of the pumping chamber connected to the clean water storage area. It is used for the first step of pumping water. The smaller blade angle draws the clean water into the pumping chamber, and then the clean water is pumped out and sprayed onto the mop through the first blade with a larger angle. The first blade with a larger angle can provide greater water pressure and flow rate.

[0090] In addition, the pump casing of the water pump can be set as a conventional fixed non-rotating structure, or can be set as a structure that rotates synchronously with the impeller in this embodiment, and the pump casing and the second blade in this embodiment are an integrated structure.

[0091] More specifically, in the present invention, the positioning hole is as follows Figure 3 As shown: it includes a blind hole 7321 located on the fixed plate and a through hole 7322 located on the lifting plate. The blind hole and the through hole are coaxially arranged. When the mop is placed on the end of the drive shaft, the blind hole is used to achieve a supporting effect, and the lifting plate with the through hole can be raised and lowered at will without causing interference.

[0092] In this embodiment, the engaging portion is as follows Figure 7 and Figure 11 As shown: a ridge 721 provided on the outer periphery of the driving portion and a groove 722 provided on the inner side wall of the positioning hole, wherein the ridge and the groove can engage with each other to limit the circumferential rotation of the driving shaft and the lifting plate;

[0093] The structural engagement between the ridge and the groove is stable, and can be formed in one step during injection molding, which is convenient for manufacturing.

[0094] The rotating shaft of the impeller of the present invention is arranged vertically, and a plane bearing 75 is provided between the lower end of the impeller and the mop bucket; since the driving shaft extending from the impeller also serves to support the mop head, especially when a hand-pressed mop rod is used in this embodiment, the impeller will be subjected to a large axial force, which is prone to wear after long-term use. By adding a plane bearing, the smoothness of the impeller rotation can be improved while also increasing the service life of the impeller.

[0095] The working principle of the cleaning tool in this embodiment is as follows: when the mop is in normal state, the lifting plate is located in a low position, the mop is placed on the driving part to rotate, and the engagement of the engaging part drives the water pump to work, and the water pump pumps out clean water and sprays it on the mop to clean the mop; after cleaning for a certain period of time, the rotation speed of the mop head is accelerated. At a certain speed, the driving part in the mop moves toward the periphery under the action of centrifugal force, and expands the reduced gap, thereby pushing the lifting plate to a high position. At this time, the engaging part is disengaged, the water pump stops working, and the mop continues to rotate to dehydrate. Example 2

[0096] The difference between this embodiment and embodiment 1 lies in the structure of the mop bucket;

[0097] This embodiment Figure 12 As shown: the mop bucket includes a barrel body 67, and a support column 66 for supporting the mop is provided in the mop bucket. When in use, a proper amount of water is put into the mop bucket. When the lifting plate of the mop is in a low position and rotates, the wipes can contact the water surface. At this time, it is rotary cleaning. After the lifting plate is raised by increasing the speed of the mop, the wipes leave the water surface. At this time, it is rotary dehydration.

[0098] In this embodiment, Figure 13 As shown: a cleaning brush 68 is further provided in the barrel body. When the mop is located at a low position for cleaning, the cleaning brush can scrub the surface of the mop. Example 3

[0099] The difference between this embodiment and embodiment 1 lies in the structure of the driving member on the mop and the structure of the gap that cooperates with the driving member;

[0100] like Figures 14 to 17As shown: In this embodiment, the height-gradient gap is achieved by an inclined surface provided on the lifting plate, and the driving member is in the shape of a rectangular block as a whole. The driving member also has an inclined surface 54 that matches the inclined surface on the lifting plate;

[0101] The spherical driving member mainly moves by rolling, and may also be accompanied by sliding movements. When a spherical structure is adopted, the lifting plate has a higher sensitivity, that is, it can move to achieve driven lifting without a very high speed; the block-shaped driving member slides, and due to the influence of friction, the speed required for its movement will be relatively high; there is actually no advantage or disadvantage between the two, and they can be used selectively for different mop heads (different types bring different weights).

[0102] In this embodiment, the through hole 224 on the lifting plate for the boss to pass through has a hole wall 222 extending axially, the hole wall is in contact with the side wall of the step, and both the hole wall and the side wall are provided with a through opening 223, and the driving member is provided with a positioning column 52 that can be inserted into the through opening. When the driving member is located at the end with the larger gap (that is, when the lifting plate is in the low position), the positioning column is inserted into the two through openings at the same time to lock the lifting plate.

[0103] At the same time, the driving member is also provided with an elastic driving member 51 that drives it to move toward the end with the larger gap. When the mop is in operation, the lifting movement of the lifting plate is locked by the insertion of the positioning column, and then the elastic driving member is pressed against the lifting member to maintain the locked state. In this way, the shaking of the lifting plate caused by the displacement of the driving member can be avoided during normal mopping.

[0104] When the mop head rotates, the elastic driving member can provide the driving member with a certain reverse pressure (damping), so that the driving member moves more evenly under the action of centrifugal force, thereby avoiding the situation where the driving member moves to the bottom all at once.

[0105] In this embodiment, the elastic driving member is a helical compression spring.

[0106] The structure of the driving member is as follows Figure 18 and Figure 19 As shown, the driver body is plastic, with a metal counterweight 55 embedded within. The contact surface of the driver with the fixed plate has a ridge 53 to reduce friction during the driver's movement. Plastic driver components are readily available in various shapes and are cost-effective. In this embodiment, the counterweight is cylindrical (interference fit), making it relatively easy to manufacture.

[0107] In addition, in this embodiment, Figure 17 and Figure 19As shown: a limiting structure is further provided on the side where the driving member contacts the fixed disk, and the limiting structure includes a limiting protrusion 56 provided on the driving block and a limiting groove 212 provided on the fixed disk. The limiting protrusion can slide in the limiting groove, thereby limiting the movement trajectory of the driving member. Example 4

[0108] The difference between this embodiment and embodiment 1 lies in the structure of the mop bucket and the structure of the mop used with it;

[0109] like Figures 20 to 22 As shown: the mop bucket includes a barrel body 67, which has a partition plate 671 that divides its inner cavity into the clean water area and the sewage area, and a detachable cover plate 69 is provided above the clean water area. The work area is located above the cover plate, and the cover plate only covers the clean water area, so that the work area can be connected to the sewage area;

[0110] The mop used in this embodiment is the mop in embodiment 3, and the cleaning component is a cleaning brush 68, which is fixedly connected to the bottom of the working area.

[0111] The cleaning member of the present invention can adopt various cleaning components known in the prior art, including cleaning scrapers, cleaning brushes, cleaning sticks, etc. The cleaning scrapers are plate-shaped or block-shaped protrusions.

[0112] In addition, the water outlet 76 of the water pump in this embodiment (the outlet for spraying water to the mop) is also different from that in Example 1. The water outlet in Example 1 is just a through-hole, while the water outlet in this embodiment is provided with a guide structure for guiding the water flow. The direction of the water spray is adjusted by the guide structure so that the mop can be better sprayed (cleaned). Example 5

[0113] The difference between this embodiment and embodiment 1 lies in the structure of the water pump;

[0114] like Figure 23 As shown: the water pump includes a piston pump 77, which is connected to the driving part 71 and driven by the driving part.

[0115] In this embodiment, the piston pump is composed of a pump body 774 and a piston rod 771. The piston rod is located at one end of the hollow pump body, and the other end of the pump body is provided with a water inlet 7741 and a water outlet 7742. The water inlet 7741 is provided with a one-way valve that limits water inlet and outlet, and the water outlet 7742 is provided with a one-way valve that limits water outlet and outlet. When the piston rod is actuated to pump water, clean water enters the pump body from the water inlet 7741. At this time, the water outlet 7742 is blocked by the action of the one-way valve. When the piston rod is actuated to pressurize water, the water in the pump body is discharged from the water outlet 7742. At this time, the water inlet 7741 is blocked by the action of the one-way valve.

[0116] More specifically, both ends of the connecting rod 772 are hinged to the piston rod 771 and the eccentric wheel 773 respectively. The eccentric wheel is connected to the driving part through a gear mechanism, and the rotational motion is converted into linear motion through the eccentric wheel mechanism.

[0117] In this embodiment, the supporting part and the driving part are both rotatable supporting columns, and the gear mechanism includes a driving gear 775 located at the lower end of the supporting column and a driven gear 776 provided on the outer periphery of the eccentric wheel. The driving gear and the supporting column are an integrated structure, and the driven gear and the eccentric wheel are an integrated structure.

[0118] This embodiment Figure 24 As shown, the working area is also provided with a brush rack 681, and the cleaning parts are installed on the brush rack.
