[0002] As people's awareness of environmental protection increases, the demand for surface garbage cleaning is increasing. Existing surface garbage cleaning machines have the following problems: Large size of the whole machine: The existing machines are large in size, which leads to higher cost of the product, as well as higher packaging and transportation costs.

[0003] The top of the garbage collector is not completely sealed: The top of the garbage collector is not completely sealed, and garbage can easily flow out, causing secondary pollution.

[0004] The driving motor uses a waterproof motor: Although the waterproof motor is easy to install, the cost is relatively high.

[0005] Garbage collection uses roller brushes: The use of roller brushes increases the cost of the product and the production and processing technology is complicated.

[0006] Using ultrasonic sensors: Ultrasonic sensors are used for front obstacle detection, but this structure will destroy the appearance of the product and is costly. Summary of the invention

[0007] Purpose of the invention: The present invention aims to provide an environmentally friendly cleaning machine that collects garbage based on the inertia of water flow, so as to solve the problems existing in the prior art. The present invention achieves the following goals by optimizing the structural design: 1. Reduce the size of the whole machine: through reasonable layout, the machine's external dimensions are reduced, and the product cost and transportation cost are reduced. 2. Prevent secondary pollution of garbage: the garbage collector adopts a closed design to prevent garbage from flowing out and avoid secondary pollution. 3.

Improve reliability: improve the operating reliability and service life of the machine by optimizing the structural design.

[0008] Technical solution: The present invention provides an environmentally friendly cleaning machine for collecting garbage based on the inertia of water flow. The main body of the environmentally friendly cleaning machine consists of an upper shell, a lower shell, a trash basket and a power assembly. A solar panel is installed on the upper shell. The trash basket is provided with a flange and a handle. The front of the trash basket is also provided with a movable baffle at one end. A switch sheet is also provided on the lower shell. A rotating shaft and a magnet are installed on the switch sheet. A Hall sensor is also provided in the bottom of the lower shell near the switch sheet. The power assembly is located at the bottom of the lower shell. The power assembly includes a driving motor and an impeller. A guide ring is provided around the impeller. Water guide ribs are also provided at the bottom of the lower shell.

[0009] Furthermore, in the above-mentioned environmentally friendly cleaning machine for collecting garbage based on water flow inertia, the garbage basket is tightly fitted with the inner surface of the lower shell. The lower shell is also provided with a groove corresponding to the flange. The flange is provided with a depression. The groove is provided with a protrusion. The depression of the flange and the protrusion of the groove are installed by snap-fitting.

[0010] Furthermore, in the above-mentioned environmentally friendly cleaning machine for collecting garbage based on water flow inertia, the driving motor is sealed by an oil seal. The driving motor and the impeller are located on both sides of the bottom of the lower shell.

[0011] Furthermore, in the above-mentioned environmentally friendly cleaning machine for collecting garbage based on water flow inertia, the switch sheet and the Hall sensor are respectively arranged on both sides of the bottom of the lower shell.

[0012] Furthermore, in the above-mentioned environmentally friendly cleaning machine for collecting garbage based on water flow inertia, the solar panel is located on the top of the upper shell and is electrically connected to the driving motor.

[0013] Furthermore, in the above-mentioned environmentally friendly cleaning machine for collecting garbage based on water flow inertia, the guide ring and the water guide ribs are made of wear-resistant materials and are covered with a layer of rubber.

[0014] Furthermore, the above-mentioned environmentally friendly cleaning machine for collecting garbage based on water flow inertia also includes a wireless communication module.

[0015] Furthermore, the present invention also provides a method for collecting garbage based on water flow inertia, comprising the following steps: 1) After fully charging the above-mentioned environmentally friendly cleaning machine, place it on the water surface that needs to be cleaned. The environmentally friendly cleaning machine can float on the water surface. When the machine is running forward, the baffle will be opened to allow water and garbage to enter the trash basket, and the water will flow out of the trash basket, and the garbage will be left in the trash basket.

[0016] 2) When the machine turns or moves backward, close the baffle to form a closed space to prevent garbage from flowing out.

[0017] 3) The water flow drives the switch plate to rotate, causing the magnet to move. The Hall sensor senses the movement of the magnet, determines the operating status of the environmental cleaning machine, and adjusts the speed of the drive motor to form a speed difference to achieve turning and reversing.

[0018] 4) A guide ring is set around the impeller to protect the impeller and guide the flow, forming a water column to help the machine move forward.

[0019] 5) Water guide ribs are arranged on the rear side of the impeller to guide the water when the environmentally friendly cleaning machine moves backward, so that the environmentally friendly cleaning machine can move in a straight line.

[0020] As a preferred embodiment of the present invention, the machine of the present invention is composed of a solar panel, an upper shell, a lower shell, a trash basket, a switch sheet, a baffle, etc. The solar panel is pasted on the upper shell, the switch sheet is installed on the lower shell, and the baffle is installed on the lower shell.

[0021] The solar panel is installed on the upper shell to charge the machine and extend the machine's operating time.

[0022] The trash basket has a flange and a handle, and the flange cooperates with the groove on the lower shell. When pulling, the flange slides in the groove. When it is in position, the protrusion on the groove is inserted into the depression of the flange of the trash basket. At the same time, the opening at the handle is assembled with the clamping rib of the lower shell, and the trash basket is installed in place. When it is pulled out, the clamping rib and the groove form a hand feel.

[0023] After the trash basket is installed, it fits with the inner surface of the lower shell so that only water can pass through the gap, but garbage cannot. The baffle is located at the front of the trash basket. When the machine is running, the baffle opens, water and garbage will enter the trash basket, and the trash basket will filter the garbage. When the machine turns or moves backward, the baffle will close, forming a closed space in the trash basket, and the garbage will not flow out of the trash basket with the flow of water.

[0024] The machine uses the inertia of water flow to collect garbage, abandoning the roller brush solution of commercially available machines, saving space and reducing costs for the machine. Without the roller brush, the garbage basket can be moved to the front of the machine, reducing the size of the machine without reducing the garbage holding capacity.

[0025] The machine also uses ordinary motors instead of waterproof motors. The motor is installed inside the machine and sealed with a highly reliable oil seal. The motor is also placed inside the machine to facilitate wiring and control.

[0026] The machine does not use ultrasonic or infrared sensors as a solution for detecting obstacles in front, but instead sets up two Hall switches at the bottom of the machine. There are two switch plates at the bottom of the machine, one end of which has a rotating shaft and the other end is equipped with a magnet. When the machine moves forward, the water flow will push the switch plate, and the switch plate will rotate around the rotating shaft, causing the magnet to produce circular motion displacement. The Hall switch is located inside the machine, and when the magnet moves outside the Hall switch, it is judged that the machine is moving forward. When the machine encounters an obstacle, the machine stops running, and the magnet will return to its original position due to the lack of water flow, which is sensed by the Hall sensor. The above structure has two switches on both sides of the bottom of the machine that can determine whether the machine is turning left or right, and can also determine which side of the machine encountered an obstacle when it was moving forward.

[0027] There is a guide ring around the impeller at the bottom of the machine. On the one hand, it can protect the impeller from being damaged. On the other hand, it also has the function of guiding the water flow, so that the water can form a water column, which is conducive to forming a combined force and is more beneficial to the movement of the machine.

[0028] There are water guide ribs on the back side of the impeller, which can guide the water when the machine is in reverse, so that the machine can move in a straight line.

[0029] It can be seen from the above technical solution that the present invention has the following beneficial effects: Reduce the size of the whole machine: By optimizing the design, the size of the machine can be reduced, and the product cost and transportation cost can be reduced.

[0030] Prevent secondary pollution of garbage: The garbage collector adopts a closed design to prevent garbage from flowing out and avoid secondary pollution.

[0031] Reduce costs: Use ordinary motors and seal them with oil seals to reduce motor costs; abandon the roller brush design to simplify the production and processing technology; use Hall sensors instead of ultrasonic sensors to reduce costs.

[0032] Improve reliability: Improve the operating reliability and service life of the machine by optimizing the structural design. BRIEF DESCRIPTION OF THE DRAWINGS
