Description

Technical Field

[0001] This utility model relates to the field of cleaning machine technology, specifically a small push rod cleaning machine. Background Technology

[0002] There are currently many types of cleaning machines on the market, such as vacuum cleaners, floor scrubbers, and carpet cleaners. Functionally, they can be divided into dry vacuuming and wet vacuuming. Dry vacuuming sucks dust and dirt into the machine, while wet vacuuming uses a motor to drive a roller brush or brush head to rotate, and sprays water to wet the floor, washing away stains, dust, hair and other debris. Then, a water suction motor and water pump suck the wastewater and debris into the wastewater tank, thereby achieving the purpose of cleaning the floor.

[0003] Existing cleaning machines still have some shortcomings that need improvement: the main unit and floor brush assembly of the cleaning machines on the market are fixedly connected and cannot be disassembled during use. The cleaning machine can only clean the floor or carpet and cannot be used to vacuum other objects, such as sofas. People need to prepare a separate vacuum cleaner to vacuum the sofa and other objects, which is very inconvenient. Utility Model Content

The first output terminal is connected to the fan 10, and the second output terminal is connected to a cooling fan 11. When the motor starts, it simultaneously drives the fan 10 and the cooling fan 11. The side wall of the motor cavity 114 has a heat dissipation vent 115, and the side wall of the fan cavity 113 has an exhaust vent 116.

[0047] A wastewater recycling tank 12 is detachably connected to the housing 109. Specifically, the housing 109 has a recycling tank mounting groove 117, in which the wastewater recycling tank 12 is embedded. A third locking component, a third button 13, is provided between the wastewater recycling tank 12 and the recycling tank mounting groove 117. A slot 118 is provided on the side wall of the recycling tank mounting groove 117, and a locking block 1301 is provided on the third button 13. When the wastewater recycling tank 12 is installed in the recycling tank mounting groove 117, the locking block 1301 is embedded in the slot 118. Pulling the third button 13 disengages the locking block 1301 from the slot 118, allowing the wastewater recycling tank 12 to be removed.

[0048] The wastewater recycling tank 12 includes a tank body 1201 and a tank cover 1202, with the tank cover 1202 connected to the open end of the tank body 1201. The wastewater recycling tank 12 is equipped with a recycling pipe 1203 assembly, which includes a recycling pipe 1203 and a reversing connecting pipe 1204. The reversing connecting pipe 1204 is a T-junction pipe, with an inlet at its lower end and outlets on both sides. The recycling pipe 1203 is fixedly connected inside the bucket body 1201, and the lower end of the recycling pipe 1203 passes through the bottom wall of the bucket body 1201 and is connected to the cleaning channel; the reversing connecting pipe 1204 is provided on the bucket lid 1202, and when the bucket lid 1202 is placed on the bucket body 1201, the reversing connecting pipe 1204 is connected to the upper end of the recycling pipe 1203; dirty water in the cleaning channel is drawn into the recycling pipe 1203, and then drawn into the bucket body 1201 through the reversing connecting pipe 1204.

[0049] The barrel lid 1202 is provided with a baffle 1205, and the reversing connecting pipe 1204 and the gas outlet 1206 are respectively located on both sides of the baffle 1205. When the main unit 1 is in a horizontal position, the horizontal height of the gas outlet 1206 is higher than the horizontal height of the reversing connecting pipe 1204.

[0050] A filter assembly 1207 is provided inside the bucket lid 1202. A gas outlet 1206 is located on the bucket lid 1202 and is connected to the inlet of the filter assembly 1207. The outlet of the filter assembly 1207 is connected to the fan 10. That is, a ventilation hole is provided on the top wall of the recycling bin mounting slot. The air blown out of the outlet of the filter assembly 1207 enters the fan 10 after passing through the ventilation hole. Dirty water in the cleaning channel can enter the dirty water recycling bin 12 through the recycling pipe 1203 assembly. Then, the gas discharged from the gas outlet 1206 is filtered by the filter assembly 1207 before entering the fan 10.

[0051] The floor brush assembly 2 can be a dry suction floor brush, a wet suction floor brush, or a dry / wet suction floor brush. The floor brush rollers of the floor brush assembly 2 can be electric or non-electric. The wet suction floor brush is equipped with a cleaning fluid tank 203, which is connected to a spray assembly 204. The cleaning fluid in the cleaning fluid tank 203 is sprayed onto the surface to be cleaned through the spray assembly 204.

[0052] When the small push rod cleaning machine disclosed in this utility model is working, if it is wet washing, the spray assembly 204 sprays the cleaning liquid in the cleaning liquid tank 203 onto the surface to be cleaned. Then, the main unit 1 is started, and the suction channel of the floor brush assembly 2 draws in the dirty water from the surface to be cleaned. The dirty water passes through the inner cavity of the rotating part 5 and the connecting head 7, and then enters the cleaning channel in the main unit 1. Then, it enters the suction recovery pipe 1203 and is discharged into the dirty water recovery tank 12 through the reversing connecting pipe 1204. The gas in the dirty water recovery tank 12 enters the filter assembly 1207 through the gas outlet 1206, and then enters the fan 10. The operation of the fan 10 discharges the gas out of the housing 109 through the exhaust port 116.

[0053] If it's a dry suction, the path is the same as a wet cleaning path, meaning there's no need to spray cleaning solution.

[0054] Main unit 1 can also be disassembled and used independently. Simply attach a brush head to the air inlet of main unit 1, and it will be ready to use. It is very convenient to use.

[0055] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
