Description

Floor brush module for floor washing machine and floor washing machine

Technical Field

The utility model belongs to the field of household washing and cleaning, and particularly relates to a floor washing machine, in particular to a floor brush module for the floor washing machine and the floor washing machine.

Background

With the development of household cleaning technology, household cleaning equipment is gradually diversified, and more cleaning equipment is introduced into thousands of households. The traditional dust collector has certain use limitation, and the structural design and the sealing performance of parts of the traditional dust collector can only meet the use scene of a dry environment but cannot be used in a wet environment; when the motor is in a wet environment, sewage carried by dust collection airflow inevitably permeates into the motor under the action of negative pressure, and once water enters the motor through a gap of the shell at the motor, the motor is easy to lose efficacy and damage.

Obviously, the cleaning machine that only can the dust absorption but can not absorb water can not satisfy consumer's user demand, for this part enterprise has researched and developed the floor cleaning machine that homoenergetic used under two kinds of environment of doing wet, in order to deal with two kinds of use scenes of doing wet better, the floor cleaning machine after the improvement need focus on the cleanness to the round brush extraordinarily, in order to avoid inside production health dead angle, so, the convenience degree that the round brush was dismantled will influence user experience greatly, current round brush participates in fixed part more, it is all very inconvenient to dismantle and install.

To this end, chinese patent application No. CN201910914469.9 discloses "a method for replacing a floor brush for cleaning with one-touch roller brush", in which a movable end cap is provided at an end of a roller brush chamber, the end cap is detached with one-touch method, so that a user can detach the roller brush body quickly only by unlocking the end cap, and the end cap is positioned at an outer end of the roller brush body. Although the floor brush adopts a side-mounted mode to realize quick disassembly, the side mounting is troublesome, the mounting opening of the side part is often very small, and sundries are easily accumulated in the disassembly and assembly process. Of course, there is also a form of upper disassembly, for example, chinese patent application No. CN202111246601.7, which is a "floor brush and cleaning device", in which a water tank assembly is set as a locking driving force of a locking assembly on a bracket assembly, and the gravity of the water tank assembly is used to control the opening and closing of the locking assembly, so that the locking assembly automatically unlocks a rolling brush assembly after the water tank assembly is taken out, and the locking assembly automatically locks the rolling brush assembly after the water tank assembly is mounted, thereby omitting the step of manually unlocking the locking assembly.

Therefore, further improvements to the floor brushes of existing floor washers are needed.
