Technical Field
[0001] This utility model belongs to the field of cleaning product structure technology, specifically referring to a mop that separates clean water and wastewater. Background Technology
[0002] Mops are essential tools for household cleaning, and there are many types and functions of mop buckets available. Among them, spin mop buckets and mops are among the everyday products that have emerged in recent years for convenient mopping. Mop buckets that separate clean and dirty water have appeared on the market, allowing the mop to be rinsed with clean water from the clean water bucket, resulting in better cleaning.
[0003] For example, Chinese patent CN202120259509.3 describes a rotating mop bucket for cleaning, comprising a bucket body with a cleaning mechanism inside. The cleaning mechanism includes a rotating water spray device and a floating extruder. The extruder has a spray nozzle connected to the rotating water spray device. In use, an external mop is rotated and installed inside the bucket, driving the rotating water spray device to rotate and spray water, causing the extruder to contact the wiping material at the bottom of the mop. A cleaning disc is provided inside the bucket, and the extruder slides vertically on the cleaning disc. The extruder includes a slider with multiple scraping teeth evenly spaced at its upper end along a straight line. The cleaning disc inside the bucket has a groove for the slider to slide. The spray nozzle is located on the slider or scraping teeth. This product significantly improves the cleaning effect, but it also has some shortcomings: because the rotating shaft is fixed inside the clean water zone, the larger clean water zone cannot accommodate a mop head. During packaging, the mop head is placed on top of the clean water zone lid, without being built into the container, resulting in wasted space and a larger mop bucket size. Summary of the Invention

[0036] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Figure 1-12 As shown:
[0037] A mop that separates clean water and wastewater includes a mop bucket 1 and a mop handle. A baffle 12 is provided in the middle of the mop bucket 1, dividing the bucket into a clean water zone and a water storage zone. The inner side of the baffle 12 is the clean water zone, and the outer side of the baffle 12 and the space between it and the mop bucket form the water storage zone. A bucket lid 13 covers the baffle, shielding the clean water zone. A pumping device is installed inside the baffle 13 to extract liquid from the clean water zone. The pumping device includes an impeller 5, a drive shaft 4, and a liquid extraction channel 3. The impeller 5 is rotatably mounted at the bottom of the clean water zone, and the drive shaft 4 is connected to and drives the impeller 5 to rotate. Wheel 5 guides the liquid through the suction channel 3 to the top of the bucket lid 13 and sprays the liquid upwards or diagonally upwards; the mop includes a mop head 2 and a mop handle, the lower end of the mop head 2 is provided with a connecting hole 22, and the connecting hole 22 is provided with an engagement part; the lower end of the drive shaft 4 is connected to the impeller 5, and the upper end of the drive shaft 4 passes through the bucket lid through hole 131 and is exposed outside, the exposed end of the drive shaft 4 is provided with a connecting part 419 that cooperates with the engagement part, the engagement part and the connecting part are connected, and the mop head can drive the drive shaft and the impeller to rotate; the connecting part and the engagement part are not specifically marked in the figure, the connecting part 419 can be as follows Figure 11 and 12 The groove shown can be fitted with a protrusion, which engages with the groove to drive the impeller. The mop head rotates by engaging the protrusion and groove. Removing the drive shaft creates a storage space in the clean water area, where the mop head can be placed. The drive shaft is small; during packaging, the drive shaft can be placed inside the storage space or outside. Figure 4 and Figure 5 As shown, the hinge joint 21 of the mop bucket is folded and placed inside the clean water area. The hinge joint 21 is used to connect the mop handle. Preferably, the multi-section threaded mop handle can also be placed inside the clean water area. Of course, the mop handle can also be placed outside the clean water area; the placement of the mop handle is determined by the manufacturer. The attached figure shows the impeller technical solution. In addition to the impeller method, a water pump can also be installed at the bottom of the mop bucket. The drive shaft rotates to drive the water pump to move and pump liquid. The water pump can be a commercially available plunger pump or centrifugal pump, as can be found in Chinese Patent CN202011402030.7.
[0038] To reduce the height of the mop bucket's outer wall, at least the following solutions can be adopted: Solution 1, a soft rubber section 112 is provided in the middle of the outer wall 11 of the mop bucket, the soft rubber section 112 divides the outer wall 11 of the mop bucket into an upper ring 111, a soft rubber section 112, and a lower body 113; pressing the upper ring 111 and deforming the soft rubber section 112 causes the upper ring 111 to move downward and be located on the side of the lower body 113, thereby reducing the height of the outer wall 11 of the mop bucket; Figure 1-2 As shown, the outer wall of the mop bucket is in the unfolded state, and the outer wall of the mop bucket is higher than the top of the baffle; as Figure 3-5As shown, the outer wall of the mop bucket is folded, and the outer wall of the mop bucket is lower than the upper end of the baffle. This structure reduces the height of the mop bucket in the folded state, and with the mop head built into the clean water area, the overall volume of the mop bucket and mop after packaging is effectively reduced. This effectively reduces the height of the bucket in the stored state, resulting in lower packaging and transportation costs. Especially in foreign trade, more products can be placed in the same container, effectively reducing product export costs. Solution 2: The outer wall of the mop bucket includes an upper ring and a lower body that are connected to each other. The upper ring and the lower body are connected by a buckle. By opening the buckle, the upper ring can be removed and can be fitted onto the outside of the lower body or placed in the water storage area. Solution 2 is not shown in the accompanying drawings. The outer wall part of the mop bucket can be referred to in Chinese Patent CN201520624241.3.
[0039] The bottom of the mop bucket has a concave cavity 122. The impeller 5 is rotatably disposed within the concave cavity 122, and an impeller cover 51 is placed on top of the impeller 5. The impeller cover 51 and the concave cavity 122 form a liquid extraction chamber. By setting the concave cavity, the impeller can be positioned at the bottom of the clean water area, allowing the impeller to extract more clean water from the clean water bucket upwards. Clean water can enter the liquid extraction chamber through the holes or gaps in the impeller cover. The impeller 5 includes a main body with an upward arch in the middle. Several impeller blades 50 are integrally formed on the arched surface. The upward arch allows the outermost impeller blades 50 to have a larger pushing surface, resulting in better agitation and liquid extraction. The concave cavity has an arched portion 123 that is adapted to the impeller.
[0040] The liquid extraction channel 3 includes a longitudinal channel 32. The lower end of the longitudinal channel 32 is connected to the liquid extraction chamber where the impeller is located through the liquid inlet channel 31, and the upper end is connected to the liquid outlet 33 on the bucket cover. The shape of the liquid inlet channel and the liquid outlet is not limited. The liquid inlet channel only needs to be able to connect to the liquid extraction chamber, and the liquid outlet can spray liquid upward or obliquely upward. The clean water area is adapted to the mop head. The baffle extends outward to form a relief part 121. The longitudinal channel 32 is located in the relief part 121. The mop head is placed in the baffle 12. The longitudinal channel 32 does not obstruct the mop head 2.
[0041] A metal support shaft 43 is fixedly installed in the middle of the drive shaft 4, and the metal support shaft 43 cannot be detached from the drive shaft 4. The detachable connection of the drive shaft 4 can be achieved in at least the following ways: Method 1: A detachable structure is used between the lower shaft of the drive shaft and the impeller, such as a snap-fit connection, key connection, or threaded connection; the metal support shaft is used for structural reinforcement. Method 2: A detachable structure is used between the metal support shaft and the mop bucket, such as a snap-fit connection, key connection, or threaded connection; the lower shaft and impeller are snap-fitted, keyed, or threaded connected, and the lower shaft can drive the impeller to rotate. The attached diagram shows the engagement between the protruding rib 429 of the lower shaft and the groove of the impeller to achieve synchronous rotation, with the metal support shaft threadedly connected to the mop bucket. The specific detachable connection method is determined by the manufacturer; a tight fit method can also be used, as long as a detachable connection is achieved.
[0042] The drive shaft 4 has a raised edge 412 on its inner side, and the metal support shaft 43 has an annular groove 431, with the raised edge confined within the annular groove; alternatively, the drive shaft has an annular groove on its inner side, and the metal support shaft has a raised edge, with the raised edge confined within the annular groove. This structure allows the rotating shaft to rotate using the metal support shaft, increasing the product's degree of freedom.
[0043] The drive shaft includes an upper shaft 41 and a lower shaft 42 that are fixed to each other. The upper shaft 41 and the lower shaft 42 can be fixed by means of a snap-fit 418, a screw, or a threaded connection. A rotating sleeve 44 is provided between the convex edge 411 of the upper shaft and the convex edge 421 of the lower shaft. The rotating sleeve 44 is used to abut against the mop head 2. Preferably, a bearing 45 is provided at the lower end of the rotating sleeve 44. This bearing is preferably a thrust bearing to reduce the rotational resistance of the rotating sleeve 44.
[0044] The core of this application is that the mop head can be placed in the clean water area. Therefore, this application does not provide a specific description of the mop head. The mop head can drive the drive shaft to rotate through the engagement part of the connecting hole at the lower end. The internal structure of the mop head can adopt a structure commonly used in the market, such as CN202120259594.3, 202120259602.4, 202421261904.5, 202220590911.4, 202120122782.1, etc.
[0045] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
