Description

Technical Field

[0001] The utility model relates to the technical field of floor sweepers, in particular to a wall-following cleaning structure for a floor sweeper. Background Art

[0002] A floor sweeper, also known as a lazy floor sweeper, is an intelligent household appliance that can automatically vacuum the floor. Because it can detect factors such as the size of the room, the placement of furniture, and the cleanliness of the floor, and rely on a built-in program to formulate a reasonable cleaning route, it has a certain degree of intelligence, so it is called a robot. A floor sweeping robot is a cleaning tool, which is divided into a push-type floor sweeper and a ride-on floor sweeper. It is a relatively advanced floor sweeping tool. A floor sweeping robot is an integrated garbage cleaning device that combines floor sweeping and vacuuming. It has the advantages of high working efficiency, low cleaning cost, good cleaning effect, high safety performance, high economic return rate, and wide application range. An electric floor sweeper is energy-saving and environment-friendly, and its usage is increasing. At the same time, it has relatively low noise and is suitable for cleaning in a quiet environment. At present, the degree of intelligence of floor sweeping robots is not as advanced as expected, but as a leader in the new concept of smart home, it will inject impetus for robots to finally enter thousands of households.

[0003] The current floor sweepers on the market can only clean the ground and cannot clean the skirting boards, resulting in an unsatisfactory cleaning effect; while the floor sweepers equipped with skirting board cleaning function cannot be adjusted according to the unevenness of the wall, and can only adjust the position of the floor sweeper to adapt to walls with different flatness, which is very inconvenient. Summary of the Utility Model

[0004] (1) Technical Problems to be Solved

[0005] The technical problem to be solved by the utility model is to provide a wall-following cleaning structure for a floor sweeper, which has a more ideal cleaning effect; can better adapt to skirting boards with different flatness, and is more convenient to use.

[0006] (2) Technical Solutions

[0007] The solution adopted by the utility model to solve the above technical problem is a wall-following cleaning structure for a floor sweeper, which includes a floor sweeper body. A driving wheel set and a rotating shaft driven by the driving wheel set are arranged in the floor sweeper body, and a detachable cleaning cloth disk is arranged at one end of the rotating shaft;

[0008] The cleaning cloth disk is externally arranged on one side of the floor sweeper body, and its installation direction matches that of the skirting board;

[0009] A floating connecting piece is arranged between the rotating shaft and the cleaning cloth disk, and the floating connecting piece enables the cleaning cloth disk to be able to stretch relative to the rotating shaft within a certain range after being connected to the rotating shaft.

[0010] With the above solution, by setting the rag tray and the mop cloth connected to the rotating shaft and arranged on one or both sides of the body of the floor sweeper to clean the skirting board, the cleaning effect is more ideal. By setting the floating connecting piece to make the rag tray float to a certain extent, it can better adapt to skirting boards with different flatness, without the need for the body of the floor sweeper to move, which is more convenient to use.

[0011] Preferably, an installation hole is provided on one side of the rag tray close to the rotating shaft, and the installation hole is provided with a limiting wall for limiting the running range of the floating connecting piece.

[0012] As a further preference, through holes are provided on at least one side of the body of the floor sweeper, and the rotating shaft passes through the through holes and is connected to the driving end of the driving wheel set so that the driving wheel set drives the rotating shaft to rotate. The rag tray is detachably connected to the part of the rotating shaft outside the body of the floor sweeper, and a mop cloth is connected to the end of the rag tray far from the rotating shaft;

[0013] A spring is horizontally installed in the installation hole, and a first limiting part for limiting the first end of the spring and a second limiting part for limiting the second end of the spring are provided in the installation hole.

[0014] In this solution, by setting the spring, when the skirting board has protrusions or depressions, the spring can stretch or compress, which can make the position of the rag tray move slightly, so as to better adapt to skirting boards with different flatness.

[0015] As a further preference, a magnetic part is provided in the installation hole, one end of the spring far from the bottom wall of the installation hole is connected to the magnetic part, the magnetic part is magnetically connected to the rotating shaft, and the first limiting part is formed by the magnetic part.

[0016] In this solution, by setting the magnetic part, it is more convenient to magnetically connect the rag tray and the mop cloth to the rotating shaft for disassembly and replacement.

[0017] Preferably, a floating connecting piece is inserted into the installation hole. A slot for the magnetic part to be inserted is provided at one end of the floating connecting piece close to the magnetic part, and a connecting hole detachably connected to the rotating shaft is provided at the other end of the floating connecting piece.

[0018] In this solution, by setting the floating connecting piece, it is more convenient for the floating connecting piece to move along the rotating shaft when the rag tray moves slightly, making the movement smoother and improving the service life of the rag tray.

[0019] Preferably, a self-lubricating copper sleeve is sleeved on the rotating shaft, and the rotating shaft rotates relative to the self-lubricating copper sleeve.

[0020] In this solution, by setting up a self-lubricating copper bushing, the rotation of the rotating shaft and the driving wheel set can be made smoother, and there is no need to frequently disassemble and apply lubricating oil.

[0021] As a further preference, the self-lubricating copper bushing is provided on the part of the rotating shaft located inside the sweeper body. A fixing seat is sleeved outside the self-lubricating copper bushing, and the fixing seat is connected to the sweeper body.

[0022] In this solution, the fixing seat is used to fix the position of the self-lubricating copper bushing so that the self-lubricating copper bushing rotates relative to the rotating shaft.

[0023] As a preference, teeth are provided on one side of the rotating shaft close to the driving wheel set, and the teeth are engaged with the gears of the driving wheel set for transmission.

[0024] In this solution, the rotation of the rotating shaft is driven by the gears that rotate synchronously with the driving wheel set to drive the teeth.

[0025] As a preference, the rag tray is connected to the mop through a magic tape.

[0026] In this solution, by setting up a magic tape, the connection and disconnection of the rag tray and the mop can be made simpler.
