Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of daily life utensils, in particular to a long and square transverse switching mop and a cleaning device thereof. BACKGROUND

[0002] The flat mop becomes the most widely used mop due to its advantages of wide mop plate, easy holding and less debris sticking. However, compared with the rotating barrel washing mode (labor-saving, separation of clean and dirty, automatic switching of washing and dehydration) of the round mop, the flat mop has obvious disadvantages in washing mode. At present, in addition to hand washing, there are three types of washing modes for the flat mop.

[0003] The first type is the washing barrel mode, which is provided with a scraper on the upper part of the washing barrel. The mop plate is cleaned and dehydrated by pushing and pulling up and down. Some are provided with two barrel cavities for washing and dehydration, which need to be manually washed first and then manually dehydrated. Some are provided with a washing and dehydration barrel cavity, which needs to drain the sewage before dehydration. This mode has the following advantages:

[0004] ① The washing barrel occupies a small area;

[0005] ② The mop can be kept upright when placed;

[0006] However, it has the following disadvantages:

[0007] ① The force required for pushing and pulling up and down during the washing process is very large. When the mop is dry or has debris sticking, it will exceed the normal housework operation bearing force;

[0008] ② The water level needs to submerge the entire mop, which requires a large amount of water;

[0009] ③ The clean water and sewage cannot be completely separated, which affects the cleaning effect;

[0010] ④ If the sewage is not drained after washing, the mop will be soaked in the sewage;

[0011] ⑤ The switching between washing and dehydration needs to be manually changed, either manually draining water or replacing the washing barrel cavity and the dehydration barrel cavity.

[0012] The second type is the push-pull scraper mode, which is installed on the mop rod to push and pull the scraper. During the washing process, it needs to be placed in a household bucket or sink to realize the cleaning function by manually pushing and pulling the push-pull scraper. This mode has the following advantages:

[0013] ① The manufacturing cost is very low;

[0014] ② The operation is relatively simple;

[0015] ③ It occupies a small area;

[0016] However, it has the following disadvantages:

[0017] ① The pushing and pulling operation during the washing process is very forceful. When the mop is too dry or has dirt stuck to it, it will exceed the normal housework operation capacity.

[0018] ② An additional washing tub or sink is required, and there is significant splashing.

[0019] ③ Its appearance is simple and it is easy to tip over;

[0020] The third type is the mop board folding method. This method divides the mop board into two or three sections, folding it into a U-shape or H-shape, thus initially realizing the transition from traditional washing to rotary drum washing. This method mainly has the following advantages:

[0021] ①The initial transformation from traditional washing to rotary drum washing has been achieved, allowing washing to be performed by placing items into a rotary drum;

[0022] ② It occupies a small area.

[0023] However, it has the following drawbacks:

[0024] ① In order to overcome the centrifugal force during rotation, a strong spring or a high-powered buckle is needed. The folding process is very strenuous, and either a lever or both hands are needed to pry it open.

[0025] ② When turned on to the flat mop mode, it cannot be turned on automatically; you still need to forcefully pry it open.

[0026] ③ Whether U-shaped or H-shaped, it is difficult to match with a brush, resulting in poor washing effect.

[0027] ④ Neither U-shaped nor H-shaped mops are the same as flat round mops, so they need to be washed in water, which requires sufficient water depth and is more wasteful of water.

[0028] ⑤ Due to the limitations of its folded shape, it cannot use the most advanced cleaning and stain separation rotary drum washing, nor can it use a rotary drum washing machine that automatically switches between washing and spin-drying. The washing effect after folding cannot be fully realized. Summary of the Invention

[0071] The operation process is as follows: when the mop assembly 1 needs to be cleaned, the switch key 16 is pulled, the sliding rack 153 is pushed to move to the middle of the fixed shell 11, the sliding rack 153 drives the switch gear 152, the switch gear 152 rotates 90 degrees and moves a certain distance to the center of the fixed shell 11 under the limitation of the fixed rack 151 and the bar-shaped guide hole, because the switch gear 152 is fixed with the driving mop plate 12, the action of the switch gear 152 will inevitably drive the driving mop plate 12 to do the same action, when the driving mop plate 12 does the above action, it will transmit the rotating force to the driven mop plate 14 through the hinge, the driving mop plate 12 drives the driven mop plate 14 to move to the center of the fixed shell 11 under the limitation of the bar-shaped guide hole of the fixed shell 11, and finally makes the driving mop plate 12 and the driven mop plate 14 rotate 90° and tightly fit, at this time, the rack clamping hook 182 is hooked with the locking clamping hook 181 synchronously, the whole switch mechanism 15 is locked, and the mop changes from an elongated mop to a square mop; after entering the washing state, the two half-cylindrical positioning sleeves 13 are combined into a complete cylindrical positioning sleeve, which is inserted into the inside of the outer sleeve ring 251 of the locking sleeve ring 25, and the bar-shaped teeth on the outer sleeve ring 251 are engaged with the bar-shaped teeth on the two half-cylindrical positioning sleeves 13; rotating the mop assembly 1 drives the locking sleeve ring 25 to rotate, the locking sleeve ring 25 drives the impeller shaft 223 to rotate, the impeller shaft 223 drives the impeller 225 to rotate, the impeller 225 rotates to make the cleaning water in the cleaning cavity of the cleaning barrel 21 flow through the pipeline into the water outlet pipe 221, and finally sprayed out by the spray head 222 to clean the mop; when the speed of the mop assembly 1 is accelerated, the counterweight is affected by the centrifugal force in the rotating process, and can overcome the elastic force of the return spring to drive the opening buckle guide plate 172 to move towards the pressing block 184, press the pressing block 184, lift the lever 183, and make the locking clamping hook 181 and the rack clamping hook 182 disengage, at this time, the locked state of the switch mechanism 15 is opened synchronously, but because the locking sleeve ring 25 on the central shaft of the rotating barrel clamps the driven mop plate 14 and the driving mop plate 12, the washing state of the mop can continue to be maintained; when the counterweight 173 receives a larger centrifugal force, the opening buckle sliding plate 171 moves along the opening buckle sliding way to the outer end, so that the bar-shaped sliding groove on the opening buckle sliding plate 171 on the upper end of the top ring 24 gradually changes from the end with a deeper groove depth to the end with a shallower groove depth, and finally lifts the mop assembly 1 to separate the locking sleeve ring 25 from the two half-cylindrical positioning sleeves 13, at this time, the mop assembly 1 no longer drives the impeller 225 to rotate, and the spray head 222 no longer sprays water flow, and enters the spin-drying mode.When the dehydrating is finished, the locking collar 25 can not continue to jam the driven mop plate 14 and the driving mop plate 12 when the mop is taken out from the rotary bucket, at this time, the action of the return tension spring begins to play, the return tension spring will pull the sliding rack 153 to move to the opposite direction of the center of the fixed shell 11, the sliding rack 153 drives the switching gear 152, the switching gear 152 will rotate 90° and move to the opposite direction of the center of the fixed shell 11 under the limitation of the fixed rack 151 and the strip-shaped guide through hole of the fixed shell 11, the action of the switching gear 152 will inevitably drive the driving mop plate 12 to do the same action, the driving mop plate 12 will conduct the rotating force to the driven mop plate 14 when doing the above action, the driven mop plate 14 will move to the direction away from the center of the fixed shell 11 and longitudinally unfold and reset under the limitation of the strip-shaped guide through hole of the fixed shell 11, and becomes a complete long flat mop.

[0072] It should be noted that the specific embodiments of the present application have been described in detail, and various obvious changes made by those skilled in the art without departing from the spirit and scope of the present application are within the protection scope of the present application.
