Description

Technical Field

[0001] This utility model mainly relates to the field of floor cleaning equipment, specifically a new type of floor cleaning machine. Background Technology

[0002] Industrial floor cleaning plays a vital role in industrial processing. It not only ensures employee safety, improves equipment efficiency and precision, and reduces production interruptions and equipment malfunctions, but also enhances product quality, reduces production costs, improves the workshop environment, and extends the lifespan of the floor. Existing industrial floor cleaning equipment primarily uses negative pressure vacuum cleaners, which suffer from the following technical challenges:

[0003] 1. Poor adaptability to ground surfaces; sealing fails on uneven surfaces, suction power relies on the tight fit between the scraper and the ground, but air leakage can occur at floor expansion joints, damaged pits, and slope joints, causing a sharp drop in suction power (wastewater residue rate exceeds 30%). Frequent replacement of flexible scrapers or custom sealing modules is required, increasing maintenance costs (e.g., special microporous nozzles are needed at epoxy floor joints).

[0004] 2. Insufficient cleaning power for heavy stains; difficult to handle viscous contaminants. Viscous stains such as machine oil and hardener residue easily clog the suction pipes, and suction cannot remove the attached layer (manual pre-washing is required). Secondary splashing of particulate matter: Hard particles such as metal shavings and grit are thrown out of the suction port's coverage area by the high-speed roller brush (common in machining workshops).

[0005] 3. Low energy efficiency; high-power vacuum system: Maintaining high suction requires a high-power fan (often 3-5kW), but the actual effective suction utilization rate is less than 40% (due to duct design losses). The continuous operating time of vehicle-mounted battery equipment is shortened (e.g., lithium battery commercial floor scrubbers only operate at full load for 1.5-2 hours).

[0006] 4. Wastewater recycling defects; incomplete gas-liquid separation: high-speed airflow carries water mist into the blower, corroding the motor and reducing its lifespan (lifespan is halved under an average of 6 hours of use per day in an industrial environment). Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a new type of floor cleaning machine that can adapt to different types and conditions of floors, resulting in better cleaning performance.

[0008] To achieve the above objectives, this utility model employs the following technical solution:

[0009] A novel floor cleaning machine includes a vehicle body, a clean water tank at the top front end of the vehicle body, a wastewater tank at the bottom of the vehicle body, a cleaning frame at the front of the vehicle body, a cleaning roller rotatably mounted on the cleaning frame, a plurality of bristles evenly arranged circumferentially on the outer wall of the cleaning roller, a cleaning motor for driving the cleaning roller to rotate on the cleaning frame, a cleaning cover mounted on the cleaning frame covering the cleaning roller, a high-pressure nozzle mounted inside the cleaning cover, a pump body inside the clean water tank, the pump body and the high-pressure nozzle connected by a pipeline, a water receiving tray between the cleaning roller and the vehicle body, and the water receiving tray communicating with the wastewater tank.

[0010] The bristles are sheet-like cleaning fabrics.

[0011] A high-pressure water pipe is installed at the front end of the top of the cleaning hood, and the high-pressure nozzles are arranged in a linear array at the bottom of the high-pressure water pipe. The high-pressure water pipe is connected to the pump body through a flexible pipeline.

[0012] The high-pressure nozzle is located above the front side of the cleaning roller.

[0013] The wastewater tank is located on the bottom of the vehicle body, and has a drain outlet on the rear side.

[0014] The water receiving tray is located above and behind the cleaning roller. The cleaning roller rotates to throw sewage into the water receiving tray for collection.

[0015] Compared with the existing technology, the beneficial effects of this utility model are:

[0016] This invention boasts strong cleaning power; physical friction can effectively remove stubborn stains such as hardened oil and tire marks. It is adaptable to various floor types and conditions, with greater tolerance for uneven surfaces (such as concrete expansion joints). The device offers precise water volume control, which, combined with friction cleaning, achieves superior cleaning results while saving over 50% more water than high-pressure washing.

[0022] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0023] like Figure 1-4 As shown, this utility model discloses a novel floor cleaning machine, comprising a vehicle body 1, which can be an electric vehicle or a fuel-powered vehicle, and can be either four-wheeled or three-wheeled. The vehicle body 1 has a seat, steering wheel, and other basic infrastructure on its top, while the power system is installed at the bottom of the vehicle body 1. A clean water tank 11 is installed at the front top of the vehicle body 1, and a wastewater tank 12 is installed at the bottom of the vehicle body 1. A pump is installed inside the clean water tank 11, which is used to pump clean water from the clean water tank 11 for cleaning the floor. Specifically, the pump is a high-pressure water pump, which can more effectively clean the dirt on the floor.

[0024] A cleaning frame 2 is installed at the front of the vehicle body 1. The cleaning frame 2, as an extension of the vehicle body 1, is used to mount the cleaning mechanism. A cleaning roller 3 is rotatably mounted on the cleaning frame 2, and a cleaning motor 21 is installed on the cleaning frame 2 to drive the cleaning roller 3. The cleaning motor 21 drives the cleaning roller 3 to rotate via a belt or transmission chain. Several bristles 31 are evenly installed circumferentially on the outer wall of the cleaning roller 3. The cleaning motor 21 drives the cleaning roller 3 to rotate, thereby using the bristles 31 on the cleaning roller 3 to perform friction cleaning on the floor, achieving a better cleaning effect on heavy stains on the floor.

[0025] Specifically, the bristles 31 can be individual dense bristles or sheet-like integrated bristles. In this embodiment, sheet-like cleaning fabrics (such as microfiber or nylon bristles) are used as bristles for hard-to-clean floors.

[0026] A cleaning cover 22 is installed on the cleaning frame 2, which covers the cleaning roller 3. The cleaning cover 22 is used to protect the cleaning roller 3 and prevent sewage from splashing and causing secondary pollution.

[0027] A high-pressure nozzle 4 is installed inside the cleaning hood 22, and a pump body is installed inside the clean water tank 11. The pump body and the high-pressure nozzle 4 are connected by a pipeline. A water receiving tray 13 is installed between the cleaning roller 3 and the vehicle body 1. The water receiving tray 13 is connected to the sewage tank 12.

[0028] A high-pressure water pipe 41 is installed at the top front end of the cleaning cover 22. High-pressure nozzles 4 are arranged in a linear array at the bottom of the high-pressure water pipe 41. The high-pressure water pipe 41 is connected to the pump body through a flexible pipeline. Specifically, the high-pressure nozzles 4 are located above the front side of the cleaning roller 3. Through the pressure of the pump body, clean water in the clean water tank 11 is introduced into the high-pressure water pipe 41. The high-pressure water pipe 41 distributes the clean water to multiple high-pressure nozzles 4, which use high-pressure water to rinse the ground in front of the cleaning roller 3, softening and cleaning the dirt on the floor. Then, the dirt is cleaned by the rotation of the cleaning roller 3. Specifically, the cleaning roller 3 rotates in the opposite direction, and the bristles directly rub against the ground to remove stubborn stains (oil, mud, sand), which is more efficient than pure suction cleaning. It can achieve better cleaning results when the vehicle is moving forward. At the same time, the reverse-rotating cleaning roller 3 can also swing the wastewater to the rear, so that the wastewater can be collected by the water receiving tray 13 at the rear.

[0029] The water collection tray 13 is located above and behind the cleaning roller 3. The cleaning roller 3 rotates, throwing wastewater into the water collection tray 13 for collection. The side of the water collection tray 13 facing the cleaning roller 3 has a slope for collecting and guiding wastewater, preventing it from flowing out. The rear side of the water collection tray 13 is connected to the wastewater tank 12, allowing wastewater to be guided into the tank for collection and temporary storage. The wastewater tank 12 is installed on the bottom surface of the vehicle body 1, and its outline corresponds to the bottom surface outline of the vehicle body 1, making full use of the bottom space of the vehicle body 1 and increasing the working time of this cleaning vehicle in one operation.

[0030] The sewage tank 12 covers the bottom surface of the vehicle body 1, and the sewage tank 12 has a drain outlet 14 on the rear side. The drain outlet 14 is closed by a gate valve or an end cap. When the sewage tank 12 is full or after cleaning, the sewage is released through the drain outlet 14.

[0031] This device combines high-pressure water spraying with friction cleaning, making it more adaptable to different types and conditions of flooring, and improving the cleaning effect and efficiency of floor stains.
