Description

Technical Field

[0001] The utility model belongs to the technical field of household articles and relates to a household cleaning device, in particular to a mop rotary cleaning device. Background Art

[0002] A mop, also known as a floor mop, refers to a long-handled cleaning tool for scrubbing the floor. It also refers to long-handled cleaning tools in general. According to the material of the mop's working head, it can be divided into rubber cotton, cotton cloth, etc., and according to the shape of the mop's working head, it can be divided into disc-shaped, flat-shaped, etc. Disc-shaped cotton mops are usually cleaned by rotating, and the cleaning process includes two steps: washing and drying.

[0003] There are many relevant documents about mop rotary cleaning devices, such as a mop bucket and mop that are easy to clean disclosed in a Chinese patent document (application number 201020172096.7). The mop bucket is provided with a cleaning area and a dehydration basket. The mop is placed in the cleaning area for cleaning and in the dehydration basket for dehydration. Another example is a mop bucket with a drying basket lift (application number 201520101774.3), which includes a barrel body and a drying basket. The drying basket rotates at the bottom of the barrel body to clean the mop head, and is lifted and positioned at the top to rotate to dry the mop head. Another example is a single-bucket rotary mop set (application date 202210735099.4). By increasing the rotation speed of the mop, the centrifugal part is forced to drive the control part to move, and the rotating mop is lifted as a whole, so as to achieve the state switching of the cleaning wiping part.

[0004] Another example is a mop bucket for separating clean water and sewage (application number 202222247429.3), which includes a mop bucket body, a clean water bucket, an impeller and a motor. When the motor rotates forward, the impeller can drive the mop head to rotate and pump liquid upward to achieve centrifugal cleaning of the mop; when the motor rotates reversely, the impeller can drive the mop head to rotate but the impeller does not pump liquid upward to achieve centrifugal drying of the mop.

[0005] The existing mop rotary cleaning device uses water and dirt to spin out in a centrifugal manner during washing and drying. Centrifugation requires the mop head to rotate at a speed exceeding a set threshold, such as 5 revolutions per second. During actual use, the mop head rotates at a high speed, the rotary cleaning device is not easy to place stably, the mop is also more difficult to be stably controlled, and the noise is greater. Summary of the invention

[0006] The utility model proposes a mop rotary cleaning device. The technical problem to be solved by the utility model is how to make the mop rotary cleaning device more stably placed when cleaning a disc-shaped mop with the mop rotary cleaning device, and the mop is easier to be stably controlled, and preferably the noise can be reduced.

[0007] The technical problem to be solved by the utility model can be achieved through the following technical solutions: a mop rotating cleaning device, the mop includes a disc and a scrubbing member installed on the bottom surface of the disc; the mop rotating cleaning device includes a cleaning bucket, a cleaning disc and a supporting member for supporting the disc are installed in the cleaning bucket, the cleaning disc has a cleaning cavity and a water drop opening, and the cleaning cavity is located outside the supporting member; the cleaning disc includes a cleaning cavity bottom wall portion, a cleaning cavity vertical wall portion connected to the outer edge of the cleaning cavity bottom wall portion, and a central boss portion connected to the inner edge of the cleaning cavity bottom wall portion; a wiper strip for contacting the bottom of the scrubbing member is fixedly connected to one end of the cleaning cavity bottom wall portion in the circumferential direction relative to the supporting member, and a water inlet structure is installed at the other end, and the wiper strip and the water inlet structure are both arranged along the radial direction of the supporting member.

[0008] When a disc-shaped mop is cleaned by a mop rotary cleaning device, the disc is placed on a support, and the scrubbing member is located in a cleaning chamber; the scrubbing member contacts the wiper strip, and the disc is driven to rotate by driving the support or directly driving the disc to rotate, so that the scrubbing member and the wiper strip generate friction. When washing, the water supply of the water inlet structure is controlled and the disc rotates counterclockwise. The water inlet structure makes the scrubbing member evenly wetted by water, and the scrubbing member and the wiper strip generate friction so that part of the water and dirt in the scrubbing member is squeezed out, and most of the water is gathered in the space surrounded by the bottom wall of the cleaning chamber, the vertical wall of the cleaning chamber, the central boss, the wiper strip and the water inlet structure. The scrubbing member will also absorb the water in the above space. Under the condition that the scrubbing member reaches the required humidity, the water supply of the water inlet structure can be reduced to reduce the amount of water used for washing.

[0009] When drying, the water inlet structure is controlled to stop supplying water and the disc rotates clockwise, the scrubbing member and the wiper strip produce friction so that the water and dirt in the scrubbing member are gradually squeezed out, and the dirt falls into the cleaning bucket through the water drop opening along with the water.

[0010] Compared with the prior art, the present mop rotary cleaning device mainly uses scraping and squeezing to squeeze out water and dirt in the scrubbing part when cleaning a disc-shaped mop. This operation method requires the disc to run at a relatively low speed, such as 1 rpm or even lower. If the speed is too high, the cleaning effect will be affected. In other words, by changing the operation method of the mop rotary cleaning device to clean a disc-shaped mop, the disc speed is achieved, the rotation stability of the disc is improved, and the mop is easier to be stably controlled, the mop rotary cleaning device is more stably placed, and the noise is lower.

[0011] Preferably, the wiper strip is sealed and connected to the bottom wall of the cleaning chamber, the central boss portion and the vertical wall of the cleaning chamber; this structure enables the wiper strip to block more water in the cleaning chamber. In other words, the structure can increase the amount of water in the space enclosed by the bottom wall of the cleaning chamber, the vertical wall of the cleaning chamber, the central boss portion, the wiper strip and the water inlet structure, and further reduce the water supply of the water inlet structure while ensuring that the scrubbing component reaches the required humidity.

[0012] Preferably, the wiper strip is connected to the cleaning disc as a whole, which has the advantages of simple structure, high sealing performance of the sealed connection and low manufacturing cost; or the wiper strip is connected to the cleaning disc through a detachable structure, which allows the wiper strip to be replaced according to actual conditions.

[0013] Preferably, the wiper strip has an upright side surface and an inclined side surface, one side of the upright side surface is an open water drop opening, the inclined side surface is located on the other side of the upright side surface, and the top surface of the wiper strip and the top surface of the bottom wall of the cleaning chamber are transitioned through the inclined side surface. During washing, the inclined side surface smoothly transitions to reduce the amount of water squeezed out of the scrubbing member, thereby improving the washing effect and efficiency; during drying, the edges and corners between the upright side surface and the top surface are used to squeeze the scrubbing member, thereby increasing the amount of water squeezed out of the scrubbing member, thereby improving the drying effect and efficiency.

[0014] Preferably, the water inlet structure may adopt any one of the following water inlet structures according to actual conditions. First, the water inlet structure includes a water inlet roller and a water storage groove located on the bottom wall of the cleaning chamber, the water inlet roller is embedded in the water storage groove, the water inlet roller is rotatably connected to the cleaning disc, and the side of the water inlet roller is provided with a water-spinning wing portion arranged along its axial direction; water is first supplied to the water storage groove, and during the washing process, the scrubbing element drives the water inlet roller to rotate, and the water-spinning wing portion spins the water in the water storage groove onto the scrubbing element.

[0015] The second type is that the water inlet structure includes a strip-shaped nozzle, and a plurality of water spray holes arranged along the longitudinal direction of the nozzle are opened on the top surface of the nozzle; water is sprayed out through the water spray holes and sprinkled on the scrubbing member.

[0016] Preferably, the cleaning bucket has a partition that divides the bottom of the inner cavity into a clean water cavity and a dirty water cavity; a water pump that can transport water in the clean water cavity to the water inlet structure is installed on the cleaning bucket. When drying, dirt falls into the dirty water cavity through the water drop opening along with the water, thereby achieving separate storage of clean water and dirty water.

[0017] Preferably, the water pump comprises a motor and a pump assembly having a main shaft, the pump assembly is located in the clean water chamber, the main shaft is vertically arranged, the rotating shaft of the motor is drivingly connected to the main shaft of the pump assembly; the support is fixedly connected to the top of the main shaft of the pump assembly.

[0018] Preferably, a side scraper for contacting the outer edge of the scrubbing member is provided in the water drop opening, and the side scraper is fixedly connected to the cleaning disc. The side scraper contacts the scrubbing member, and especially during the drying process, the accumulated water at the outer edge of the scrubbing member is scraped off, thereby improving the drying effect and efficiency.

[0019] Preferably, the side scraper is in sheet form and is elastic; the side scraper is in flexible contact with the scrubbing member, which significantly reduces the possibility of the side scraper damaging the scrubbing member and reduces the resistance of the side scraper to the rotation of the disc, thereby improving the drying effect and efficiency.

[0020] Preferably, the end of the side scraper for contacting the outer edge of the scrubbing member is called the wiper portion, and the wiper portion is serrated; this structure further reduces the possibility of the side scraper damaging the scrubbing member and reduces the resistance of the side scraper to the rotation of the disc, as well as improves the drying effect and efficiency.
