Design and working principle of the present utility model are:

(1) Selection of cleaning method

According to our information, investigation and visits, the current effective cleaning methods are almost all the relative rotation between the brush and the object to be cleaned, such as the road cleaning vehicle, which relies on the rotation of the brush and the road to stir up the dust and relies on negative pressure. Vacuum. For the cleaning of the ceiling, its main purpose is to eliminate the adhesion between the dust and the ceiling, and the dust can fall by its own weight without negative pressure vacuuming. Therefore, as long as the brush has a rotating motion, it can meet the needs of dust removal. Or, an important reason for choosing a brush is to avoid cleaning tools from damaging the ceiling. Based on the above considerations, we believe that the rotating motion of the brush is the most effective and reasonable way to clean the ceiling.

(2) Selection of transmission mode

To realize the rotary motion of the brush, there are many ways to convert the motion, which can be rotary motion-rotary motion, or linear motion-rotary motion. Rotary motion——The motion conversion method of rotary motion, the original motion is rotary motion, which requires a certain transmission mechanism to transmit the motion to the brush, which is neither simple nor practical for a hand-held household cleaning tool. There are many ways of motion conversion mechanism for linear motion-rotary motion, such as screw pair, rack and pinion pair, cam mechanism, linkage mechanism, etc. For a tool that people hold and use, the simpler the structure, the lighter it is, the more convenient it is to use, the better. Compared with the above linear motion-rotary motion conversion methods, we think that the screw pair is the best choice. The screw pair includes sliding screw pair, rolling screw pair, and static pressure screw pair. If the rolling screw pair and static pressure screw pair are used on hand tools, the structure is more complicated, so the trapezoidal sliding screw pair is selected to convert linear motion into rotary motion. The advanced motion conversion mechanism is simple in structure and easy to use.

(3) Power mode selection

The driving force behind the rotating motion of the hairbrush can be electric or manual, and the electric power can be an AC power supply or a storage battery. If the AC power supply is used, it will be inconvenient for people to use; Increase, lost the convenience of hand-held tools, after repeated analysis and comparison, choose manual as the power source of the brush, through the simulation test, one hand-held tool body, the other hand-held screw push rod, push and pull up and down, it is very convenient to use.

(4) Description of other main structures

The brush should be in vertical contact with the ceiling, which requires the user to hold the handle perpendicular to the ceiling, which makes the user very tired and inconvenient to use. Therefore, a universal joint is designed at the connection between the brush and the connecting rod. The connection allows the user to tilt the hand-held rod at a certain angle, which is in line with people's habits of using tools; a needle bearing is set between the outer tube and the inner tube, which separates the rotary motion of the inner tube from the outer tube, and pushes and pulls the screw The force of the push rod is transmitted to the long tube; the rotating brush in the dust tray is in contact with the ceiling to clean the dust.

The utility model has completed the research and development of the ceiling cleaner by making relevant selections to the above cleaning mode, transmission mode, power mode, etc. The rotary motion of the screw push rod is converted into linear motion through the pin nut sleeve, which is transmitted to the cleaning brush to clean the ceiling, while the cleaning plate at the lower end carries and stores the dust. The cleaner can choose different brushes according to different ceiling materials; adjust the telescopic secondary rod according to different ceiling heights to meet the requirements; you can also adjust the angle of the cleaning disc according to different angles. The design has met the expected design requirements and has a good development scenario.

The beneficial effects of the utility model are:

According to the principle that dust will fall by its own weight, the design of the rotating brush removes the functional module of negative pressure adsorption, thereby reducing the weight of the ceiling cleaner. Because the area of the dust tray is larger than that of the rotating brush, the dust falls into the dust tray, which can effectively prevent the dust from scattering around. In addition, when the helical push rod is not perpendicular to the ceiling, the universal joint allows the rotating brush to still be close to the ceiling effectively, and the cleaning angle can be selectively changed, which is convenient for users and reduces the burden of cleaning the ceiling for users.

Moreover, compared with the traditional cleaning method, the ceiling cleaner has an additional manual activation device—a screw push rod. The outer sleeve and rotating brush bar allow the user to use both hands for simple relative linear motion. The helical pair converts this linear motion into rotational motion of the brush shaft and bristles. With this screw-type push rod, we can save effort, and the efficiency is higher, and the cleaning effect will be better. Thereby, the user's operation is simplified, and the efficiency of the cleaner is also improved. In addition, this cleaner is a purely manual device, so there is no need to install batteries and other electric equipment, thereby reducing the weight and further reducing the burden on users to clean the ceiling.

In addition, the telescopic rod structure is convenient for us to send the cleaning brush to the desired position, and takes up little space. There are detachable joints between the brush handle and the brush rod and between the brush rod and the brush handle. Each part can be disassembled and placed. When not in use, the user can disassemble and store the cleaner, thereby saving storage space.

Finally, it is highly expandable, and the brush rod can also be equipped with an adjustable-length secondary push rod connected with a screw-type push rod. In this way, the user can adjust the length of the brush rod according to his height and the actual condition of the roof, which facilitates the user's operation. In order to better reduce human labor, an intelligent mobile trolley can also be installed at the bottom of the brush handle. After adjusting the height of the brush pole, fix the ceiling cleaner on the mobile trolley to realize the automatic cleaning of the ceiling setting track .
