Description

Technical Field

[0001] The present disclosure relates to the technical field of intelligent cleaning equipment, and in particular to a lifting system for intelligently adjusting the height of a roller brush of a cleaning equipment from the ground. Background Art

[0002] Cleaning equipment refers to tools and equipment used to clean and maintain environments, facilities and equipment. These equipment usually include various vacuum cleaners, steam cleaners, washing machines, etc. The use of cleaning equipment can help people clean and maintain various places more efficiently and improve the hygiene level of living and working environments.

[0003] At present, the aging degree of society is getting higher and higher, and higher technology is needed to fill the various inconveniences in life. In particular, the commercial and public cleaning industries are mostly employed by older practitioners. Cleaning work is physically arduous. Some floor cleaning relies entirely on human pressure or the use of equipment weight to apply pressure. The cleaning force and downward pressure cannot be quantified. The problems caused are fatigue of personnel, substandard cleaning or excessive cleaning causing destructive cleaning. Therefore, more and more intelligent systems and products are needed to replace a large amount of labor and tedious and repetitive work to solve the above-mentioned inconveniences. For this reason, we have invented a lifting system that intelligently adjusts the height of the roller brush of the cleaning equipment from the ground to enrich more intelligent cleaning equipment products, so that more cleaning equipment products in society are more intelligent, more convenient to use, and have better cleaning effects.

[0004] The published Chinese patent application number is: 202222489746.6, which discloses a vacuum cleaning robot, including: a chassis, a side brush module, a roller brush module and a dust pusher module arranged in sequence below the chassis from the front to the back of the vacuum cleaning robot, and a first lifting drive assembly, a second lifting drive assembly and a third lifting drive assembly fixed to the chassis and used to control the lifting of the side brush module, the roller brush module and the dust pusher module respectively. The vacuum cleaning robot can select an appropriate single cleaning module or a combination of any cleaning modules to perform cleaning work according to the degree of dirtiness of the ground and / or the material of the ground.

[0005] The above patent is aimed at selecting cleaning modes according to the degree of dirtiness of the ground or the material of the ground, and using the side brush module, roller brush module and dust pusher module to independently lift and adjust to achieve cleaning functions in different modes. On the one hand, this method is relatively expensive, making the cleaning robot itself heavy and bulky, and more power-consuming, especially when used outdoors or in large households, requiring frequent charging. On the other hand, some stubborn stains on the ground are not easy to clean, requiring repeated cleaning by the sweeping robot or additional manual cleaning, which is troublesome, time-consuming and labor-intensive. Therefore, we propose a lifting system that intelligently adjusts the height of the roller brush of the cleaning equipment from the ground to solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to provide a lifting system for intelligently adjusting the height of the roller brush of a cleaning equipment from the ground, so as to solve the technical problems in the prior art, especially in the commercial and public cleaning industries, where most of the employees are older and the cleaning work is physically arduous. Some floor cleaning relies entirely on human pressure or the use of the equipment's own weight to apply pressure, and the cleaning force and downward force cannot be quantified. The problems brought about are employee fatigue, substandard cleaning or excessive cleaning causing destructive cleaning, so more and more intelligent systems and products are needed to replace the large amount of labor and tedious and repetitive work.

For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0040] See also Figures 1 to 5 The present invention provides a lifting system for intelligently adjusting the height of a roller brush of a cleaning device from the ground, comprising a lifting component 1 and a cleaning component 2.

[0041] The cleaning components of a cleaning device refer to the parts used for cleaning operations. Different cleaning devices may have different cleaning components. Among them, the brush mainly removes dirt by friction between the bristles and the surface of the cleaned object. The bristles of the brush can be hard, soft, or the length and shape of the bristles can also be different. Different brushes are selected according to different cleaning needs.

[0042] In general, the working principle of the cleaning component mainly includes friction, scraping, suction, spraying and other methods to remove dirt and dust. Different cleaning components are suitable for different cleaning scenes and materials. When using, you need to choose the appropriate cleaning component according to the actual situation.

[0043] The side surface of the lifting assembly 1 is connected to the cleaning assembly 2, and the lifting assembly 1 includes a lifting fixed plate 1.4 connected, and a lifting motor 1.1 is arranged on the outer wall of the lifting fixed plate 1.4, and one end of the lifting motor 1.1 is connected to the lifting gear box 1.2. The lifting assembly 1 is provided with a lifting cam 1.3 rotated by the lifting gear box 1.2, and the gear box is a mechanical device for increasing and reducing by decelerating / increasing torque. It consists of two or more gears, one of which is driven by a motor. The output speed of the gearbox is inversely proportional to the gear ratio. The gearbox is usually preferred in constant speed applications, such as conveyors and cranes, which can provide increased torque. The gearbox is a mechanical device for increasing and reducing by decelerating / increasing torque. It consists of two or more gears, one of which is driven by a motor. The output speed of the gearbox is inversely proportional to the gear ratio. The gearbox is usually preferred in constant speed applications, such as conveyors and cranes, which can provide increased torque.

[0044] The gearbox consists of a driving gear with a certain diameter, connected to the driving mechanism (electric motor, wind turbine, diesel engine, etc.) and another gear of a smaller diameter (if the driven mechanism has a higher driving speed than the driving mechanism) (if the speed of the driven mechanism should be less than the speed of the driving mechanism) connected to the driven mechanical load. It is just a speed / torque increase / i decrease or vice versa mechanism. This is a mechanical motor attachment;

[0045] In the first embodiment of the present invention, when the roller brush pressure on the ground is

[0046] Dynamic friction formula F = μFN

[0047] Fn represents positive pressure, which is the positive pressure of the cleaning component due to its own gravity, i.e. the roller brush on the ground.

[0048] The friction coefficient μ has different values ​​due to different working environments of the cleaning robot, different contact materials and different contact heights between the roller brush and the ground. According to the first embodiment, it is measured as follows:

[0049] When the roller brush is -0mm from the ground, hard floor μ = 0.1, short-hair carpet μ = 0.15, long-hair carpet μ = 0.2

[0050] When the roller brush is -1mm from the ground, hard floor μ = 0.123, short-hair carpet μ = 0.174, long-hair carpet μ = 0.232

[0051] …

[0052] F = μ (related to material and roller brush ground clearance) fn roller brush ground pressure (constant)

[0053] The smoother the material and the larger the ground clearance of the roller brush, the smaller the friction. On the contrary, the rougher the material and the smaller the ground clearance of the roller brush, the greater the friction.

[0054] Friction force of roller brush against the ground = resistance of roller brush against the ground and related roller brush torque

[0055] In the first embodiment, the speed of the motor of the cleaning robot's roller brush is constant, and the motor voltage is constant

[0056] W = (torque) * speed * PI / 30, PI is the constant pi 3.1415926

[0057] That is, W = rolling brush resistance to the ground * speed (constant value) * rolling brush diameter (constant value) * 3.1415926 / 30

[0058] It can be obtained that: the greater the pressure of the roller brush on the ground (that is, the smaller the clearance of the roller brush from the ground), the greater the resistance, and the greater the torque required by the roller brush. On the contrary, the smaller the pressure of the roller brush on the ground (that is, the larger the clearance of the roller brush from the ground), the smaller the resistance.

[0059] Power = voltage times current (P = UI)

[0060] That is, W(P)=24V(U)*current(I)

[0061] The above shows that when the cleaning component is lowered, the clearance of the roller brush from the ground is smaller, the pressure of the roller brush on the ground is greater, and the motor current is greater; when the cleaning component is raised, the clearance of the roller brush from the ground is larger, the pressure of the roller brush on the ground is smaller, and the motor current is smaller

[0062] According to the program in the first embodiment, the best motor current value for cleaning effect is preset, and the rise or fall of the cleaning component is adjusted according to the real-time change of the current value to determine the roller brush ground clearance, thereby reducing or increasing the roller brush pressure on the ground to achieve the best cleaning effect.

[0063] like Figure 1 and Figure 3 As shown, the cleaning component 2 includes a roller brush motor 2.1 connected thereto. The roller brush motor is a type of motor commonly used in household power tools and household appliances. Its function is to convert DC power into mechanical energy and generate a rotational force through the interaction between the roller brush and the brush. The roller brush motor consists of a DC motor and a roller brush. The DC motor provides power, and the roller brush generates friction through contact with the brush to drive the motor to rotate. One end of the roller brush motor 2.1 is connected to a roller brush gear box 2.2. A roller brush 2.4 is arranged inside the cleaning component 2. One end of the roller brush 2.4 is connected to the roller brush gear box 2.2. A cleaning cavity 2.3 is arranged on the cleaning component 2, and the cleaning cavity 2.3 moves relative to the lifting bracket 2.5.

[0064] like Figure 1-2 As shown, a connecting frame is provided on the side surface of the lifting component 1 for convenient connection with the cleaning component 2, a plurality of screw holes are provided on the connecting frame for easy disassembly and assembly, and a supporting block is connected to the connecting frame for easy clamping of the lifting motor 1.1.

[0065] like Figure 2As shown, the lifting motor 1.1 and the lifting gear box 1.2 are both provided with brackets, and the brackets are provided with a plurality of screw holes for facilitating connection with the connecting frame.

[0066] like Figure 3-5 As shown, an arc-shaped groove is provided at one end of the lifting bracket 2.5 to facilitate the insertion of one end of the roller brush motor 2.1. The bottom end of the lifting bracket 2.5 is provided with a groove that is convenient for clamping with the top of the cleaning component 2. A plurality of inclined blocks are provided on the lifting bracket 2.5 to make its structure more solid. The function of the lifting bracket is to support and adjust the height of the cleaning equipment so that it can adapt to different working environments and cleaning tasks. Through the lifting bracket, the cleaning equipment can be lifted and lowered when necessary so that the cleaning staff can better perform the cleaning work. The lifting bracket can also adjust the height of the equipment so that it can reach the area that needs to be cleaned. At the same time, the height of the equipment can also be adjusted to adapt to different work requirements and height differences of the cleaning objects. The lifting bracket can also provide stable support to ensure that the cleaning equipment can maintain balance and stability during work, thereby improving the cleaning effect and work safety.

[0067] like Figure 1 and Figure 3 As shown, the cleaning component 2 is provided with a plurality of connecting blocks for connecting between devices and facilitating disassembly and assembly. The connecting blocks are provided with grooves that fit into each other and have screw holes for inserting screws. The outer wall of the cleaning component 2 is provided with a plurality of protrusions for facilitating disassembly and assembly between components. The protrusions are provided with through holes for inserting screws, and the through holes facilitate disassembly and assembly between components.

[0068] like Figure 3 As shown, the end of the roller brush 2.4 is provided with a support shaft that can drive it to rotate, and a mounting cavity for the support shaft to be inserted is provided on the cleaning component 2, a groove is provided at one end of the mounting cavity, and a connecting plate that can be inserted into the groove is provided at one end of the support shaft, a pair of screw connection holes are provided in the groove, and a pair of screw perforations that are convenient for connecting with the cleaning component 2 are provided on the connecting plate. The benefit of using screws at the connection of the cleaning equipment is that connecting many screws can ensure that the various components of the cleaning equipment are firmly fixed together, and enhance the stability and durability of the equipment. It can also make the cleaning equipment resist vibration and impact during operation, and reduce the possibility of damage and failure of the equipment. It can also make the maintenance and maintenance of the cleaning equipment more convenient. Only the screws need to be loosened to disassemble the parts that need to be repaired, saving maintenance time and cost. It can also ensure that the various components of the cleaning equipment are firmly fixed together, avoiding the situation that the equipment is loose or falls off during operation, and ensuring the safety and reliability of the equipment. It can also flexibly adjust the position and angle of the various components of the cleaning equipment to adapt to different cleaning needs and working environments, and it can also easily replace and upgrade the components, so that the cleaning equipment can be functionally expanded and improved as needed.

[0069] Working principle: When it is necessary to use a lifting system that intelligently adjusts the height of the roller brush of the cleaning equipment from the ground, when the intelligent cleaning equipment is working, the main control board sends a cleaning command to the roller brush motor 2.1 to start the roller brush 2.4 through the roller brush gear box 2.2, and at the same time, the lifting motor 1.1 fixed on the lifting fixed plate 1.4 is turned on to drive the lifting cam 1.3 to move through the lifting gear box 1.2, and the lifting cam 1.3 and the lifting bracket 2.5 fixed on the cleaning chamber 2.3 form a relative downward movement. As the cleaning component 2 descends lower from the ground, the roller brush 2.4 will have a larger contact area with the ground to be cleaned, and the friction between the roller brush 2.4 and the ground increases. The torque output on the roller brush motor 2.1 is greater, and the working current of the roller brush motor 2.1 will change, triggering the main control board to send a signal to the lifting motor 1.1 to start, and the lifting cam 1.3 is driven to rotate according to the set working current value of the roller brush motor 2.1, and the lifting bracket 2.5 drives the cleaning component 2 to descend or rise, completing the pressure of the roller brush 2.4 on the ground to achieve the best ground cleaning effect.
