Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and in particular to a brushless cleaning machine. Background Technology

[0002] A cleaning machine is a cleaning device that is driven by a power unit and uses a pump to generate high-pressure water flow to remove dirt. It is mostly used for cleaning cars and industrial equipment. Cleaning machines are mostly divided into brushless cleaning machines that use brushless motors and traditional cleaning machines that use brushed motors. Brushless motors use electronic commutation technology and control the direction of current by sensing the position of the magnetic poles through Hall elements. They do not require the use of physical carbon brushes. At the same time, brushless motors are more efficient and have a longer lifespan, with more advantages than brushed motors.

[0003] Most brushless cleaning machines on the market have their water supply pipes externally connected to the cleaning components. This not only affects the aesthetics of the brushless cleaning machine, but the exposed water supply pipes are also prone to damage, thus preventing the brushless cleaning agent from working.

[0004] For the reasons mentioned above, it is necessary to improve the existing technology. Summary of the Invention

Detailed Implementation

[0021] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0022] Please see Figure 1-5 The present invention provides a brushless cleaning machine, including a housing 1; Cleaning component 2, wherein the cleaning component 2 is disposed on one side of the housing 1; The drive assembly 3 includes a drive housing 30 fixedly disposed in the housing 1, a brushless motor 31 fixedly disposed in the drive housing 30, and a first transmission shaft 32 rotatably disposed in the drive housing 30. The first transmission shaft 32 is driven by the brushless motor 31, and one end is fixedly connected to the cleaning assembly 2. It also includes a front fork 4, one end of which extends outward to form a hinge part 40 that is hinged to the outer shell 1, and the other end is fixedly provided with a hollow tube 41 with an end opening. The inner side of the hinge part 40 is provided with a receiving recess 42, and the front fork 4 is provided with a through hole 43 corresponding to the opening position of the hollow tube 41. The water supply assembly 5 includes a pumping device 50 disposed on one side of the hollow tube 41, a pipe opening 51 opened on one side of the outer casing 1, a water inlet 52 disposed at the top of the first drive shaft 32, a fluid channel 53 opened at the center of the first drive shaft 32, a water nozzle 54 fixedly disposed at the bottom of the first drive shaft 32, and a water supply pipe 55 disposed in the inner cavity of the hollow tube 41. One end of the water supply pipe 55 is connected to the pumping device 50, and the other end passes through the through hole 43, the receiving recess 42 and the pipe opening 51 in sequence before connecting to the water inlet 52.

[0023] In the above structure, the water supply pipe is placed inside the hollow tube cavity. One end is connected to the water pumping device, and the other end extends inside the hollow tube cavity to pass through the hollow tube opening. After passing through the through hole corresponding to the opening of the hollow tube, it passes through the receiving recess on the inner side of the fork and then through the pipe opening on the side of the outer shell to connect to the water inlet. After the water is pumped into the water pipe by the water pumping device, it flows through the water pipe into the water inlet and then flows through the fluid channel opened at the center of the first drive shaft to the water nozzle. At the same time, the first drive shaft is driven to rotate by the brushless motor, and the cleaning component fixedly connected to one end of the first drive shaft rotates synchronously to clean. The entire brushless cleaning machine hides the exposed water supply pipe inside, which not only makes the brushless cleaning machine more beautiful, but also protects the water supply pipe and makes it less likely to be damaged.

[0024] Specifically, it also includes a power supply device 6, which includes a power supply device housing 60 fixedly installed on one side of the water pumping device 50 and a battery 61 installed in the power supply device housing 60. The battery 61 is electrically connected to the brushless motor 31 and the water pumping device 50. Using the battery allows the brushless cleaning machine to continue to work in a working environment without an external power source or in the event of a power outage or other situations where power cannot be supplied.

[0025] Specifically, a first bearing 100 is provided between the first drive shaft 32 and the drive housing 30. The first bearing can prevent contact between the first drive shaft and the drive housing and reduce the coefficient of friction.

[0026] Specifically, a second drive shaft 33 is sleeved at the lower end of the first drive shaft 32, and a second bearing 101 is provided between the second drive shaft 33 and the drive housing 30. The second bearing can avoid direct contact between the second drive shaft and the drive housing and reduce the coefficient of friction.

[0027] Specifically, the cleaning assembly 2 includes a rotating disk 20 fixedly disposed at the bottom end of the water nozzle 54, a first cleaning brush 21 fixedly disposed at the bottom end of the rotating disk 20, a water baffle 22 sleeved on the lower circumference of the second drive shaft 33, and a second cleaning brush 23 fixedly disposed on the bottom surface of the cleaning housing 22. The second cleaning brush 23 is arranged around the outer circumference of the first cleaning brush 21, and its end face is flush with the first cleaning brush 21. When the first drive shaft rotates, it drives the water nozzle to rotate synchronously. The water in the water nozzle is sprayed out by centrifugal force. At the same time, the rotating disk is driven to rotate by the water nozzle, and the first cleaning brush is driven to rotate synchronously by the rotating disk to clean. The second drive shaft is driven to rotate synchronously by the first drive shaft, so that the water baffle rotates and the second cleaning brush fixedly disposed at the bottom end of the water baffle rotates synchronously. The first cleaning brush and the second cleaning brush rotate in the same direction to clean.

[0028] Specifically, the upper surface of the rotating disk 20 is provided with water guiding protrusions 200, which can guide the water flow thrown out by the water nozzle by centrifugal force, so that the water flow is directed to the designated position.

[0029] Specifically, a third bearing 102 is provided between the first drive shaft 32 and the second drive shaft 33. A first helical gear 320 with its teeth facing downwards is fitted on the first drive shaft 32, and a second helical gear 330 with its teeth facing upwards is fitted on the second drive shaft 33. The first helical gear 320 and the second helical gear 330 are arranged parallel to each other. A helical gear 310 is fixedly provided at the end of the brushless motor 31. The helical gear 310 is located between the first helical gear 320 and the second helical gear 330, and its teeth mesh with the first helical gear 320 and the second helical gear 330 respectively. The first drive shaft and the second drive shaft 33... A third bearing is installed between the drive shafts so that the first drive shaft no longer drives the second drive shaft. When the brushless motor starts, it drives the helical gear to rotate. The first and second helical gears, which mesh with the upper and lower ends of the helical gear, are driven to rotate by the helical gear. When the first helical gear rotates clockwise, the second helical gear rotates counterclockwise. The first helical gear drives the first drive shaft to rotate clockwise, which in turn drives the first cleaning brush to rotate clockwise. The second helical gear drives the second drive shaft to rotate counterclockwise, which in turn drives the baffle plate to rotate counterclockwise, thereby driving the second cleaning brush to rotate counterclockwise. This allows the first and second cleaning brushes to clean in both directions, increasing the cleaning effect.

[0030] Specifically, a limiting part 44 that cooperates with the receiving recess 42 is fixedly provided on the inner side of the front fork 4. The limiting part is used to limit the water supply pipe placed in the receiving recess, so that the water supply pipe is hidden inside the front fork, thereby increasing the aesthetics of the brushless cleaning machine and making the visual effect less obtrusive.

[0031] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
