Abstract
Description
Technical Field
[0001] This utility model relates to the field of pool cleaning machine technology, specifically to a pool cleaning machine with a propulsion device. Background Technology
[0002] There are three main types of pool cleaning machines: the first type cleans only underwater, the second type cleans only on the surface, and the third type can clean both underwater and on the surface.
[0003] The second and third types of cleaning machines (such as the walking device for water and pool cleaning robot disclosed in CN117120696A) have a problem: the water-spraying propeller of the pool cleaning machine can only propel the cleaning machine forward, but cannot assist in drainage; moreover, when the cleaning machine moves on the water surface, the water passing through the dust box exits from the bottom opening, and the water flow is not accelerated by the rotating impeller as in this application, resulting in a low water velocity, low water flow rate, and low filtration efficiency. Based on this, we propose a pool cleaning machine with a propulsion device. Utility Model Content
[0004] The purpose of this invention is to overcome the aforementioned problems in the prior art and provide a pool cleaning machine with a propulsion device. The propulsion device, which sprays water backward, can both propel the cleaning machine and assist in drainage, thereby increasing the outflow rate and speed of the filtered water and improving filtration efficiency.
[0005] To solve the above-mentioned technical problems, this utility model provides a pool cleaning machine with a propulsion device, including a housing, a propulsion device and a filter box. The propulsion device and the filter box are installed inside the housing. The propulsion device includes a propeller, which includes a propulsion impeller and a propulsion motor. The propulsion impeller is installed on the output shaft of the propulsion motor. The housing has an upper water outlet, and the propulsion impeller is directly opposite the upper water outlet. The propeller is located further behind the filter box in the forward direction of the pool cleaning machine.
[0006] The propeller should be positioned at least partially below the floating position of the pool cleaner on the water surface to ensure that when the pool cleaner is floating on the water, the rotation of the propulsion impeller in the propeller can push water backward, and the sprayed water will provide the pool cleaner with forward propulsion.
[0007] When the pool cleaning machine moves on the water surface, the upper roller brush can roll up garbage or impurities on the water surface into the filter box through the upper inlet, thereby improving the water surface cleaning efficiency.
[0008] The propulsion system includes a thruster, which is horizontally mounted in the middle of the rear of the housing to ensure the balance of the pool cleaner.
[0009] The propulsion system includes two thrusters, horizontally mounted on either side of the rear of the housing to ensure the balance of the pool cleaner. At least one thruster is located on each of the left and right sides of the pool cleaner.
[0010] When the pool cleaner moves on the water surface, the power of the propulsion motors of the left and right propellers is adjusted to adjust the speed at which the water is sprayed backward by the left and right propellers, thereby enabling the pool cleaner to turn.
[0011] The housing has an upper water inlet on the side near the filter box, and the filter box has an upper inlet on the side near the upper water inlet, with the upper inlet connected to the upper water inlet.
[0012] The housing is equipped with a baffle, which is used to adjust the opening and closing state of the upper inlet of the filter box.
[0013] It includes a water pump motor and a water pump impeller. The water pump impeller is mounted on the output shaft of the water pump motor. The housing has a lower water inlet on the lower side near the filter box. The filter box has a lower inlet on the side near the lower water inlet. The lower inlet is connected to the lower water inlet. The housing has a top water outlet on the top. The water pump motor is located below the top water outlet.
[0014] The water pump motor is located between the propulsion motor and the filter box.
[0015] In summary, this utility model has at least one of the following beneficial effects:
[0016] In this application, when the pool cleaning machine moves on the water surface, the water filtered by the filter box flows through the rotating propulsion impeller and is then discharged into the pool from the upper outlet. Thus, the propulsion device that sprays water backward can both propel the cleaning machine and assist in drainage, increasing the outflow rate and speed of the filtered water and improving the filtration efficiency.

Detailed Implementation
[0023] The following is in conjunction with the appendix Figures 1-4 The present invention will be described in further detail below.
[0024] See appendix Figure 1 and attached Figure 2 A pool cleaner with a propulsion device includes a housing 6, a propulsion device, and a filter box 4. The propulsion device and the filter box 4 are installed inside the housing 6. The propulsion device includes a propeller, which includes a propulsion impeller 1 and a propulsion motor 2. The propulsion impeller 1 is mounted on the output shaft of the propulsion motor 2. The housing 6 has an upper water outlet 3. The propulsion impeller 1 is directly opposite the upper water outlet 3. The propeller is located further behind the pool cleaner in the forward direction than the filter box 4.
[0025] When the pool cleaning machine moves on the water surface, the water filtered by the filter box 4 flows through the rotating propulsion impeller 1 and is then discharged into the pool from the upper outlet 3.
[0026] The position of the propeller should be at least partially below the floating position of the pool cleaner on the water surface, so as to ensure that when the pool cleaner is floating on the water surface, the rotation of the propulsion impeller 1 in the propeller can push water backward, and the sprayed water gives the pool cleaner a forward thrust.
[0027] When the pool cleaning machine moves on the water surface, the upper roller brush 5 can roll up the garbage or impurities on the water surface through the upper inlet 8 of the filter box and into the filter box 4, thereby improving the water surface cleaning efficiency.
[0028] The propulsion system includes a thruster, which is horizontally mounted in the middle of the rear of the housing 6 to ensure the balance of the pool cleaning machine.
[0029] See appendix Figure 1 and attached Figure 2 The propulsion device includes two thrusters, which are horizontally mounted on both sides of the rear of the housing 6 to ensure the balance of the pool cleaning machine. At least one thruster is located on each of the left and right sides of the pool cleaning machine.
[0030] When the pool cleaner moves on the water surface, the power of the propulsion motors 2 of the left and right propellers is adjusted to adjust the speed at which the water is sprayed backward by the left and right propellers, thereby enabling the pool cleaner to turn.
[0031] See appendix Figure 3 and attached Figure 4 The housing 6 has an upper water inlet 7 on the side near the filter box 4, and the filter box 4 has an upper inlet 8 on the side near the upper water inlet 7. The upper inlet 8 is connected to the upper water inlet 7.
[0032] The housing 6 is equipped with a baffle 13, which is used to adjust the opening and closing state of the upper inlet 8 of the filter box 4.
[0033] See appendix Figure 2 and attached Figure 3 The system includes a water pump motor 12 and a water pump impeller 14. The water pump impeller 14 is mounted on the output shaft of the water pump motor 12. The housing 6 has a lower water inlet 9 on the lower side near the filter box 4. The filter box 4 has a lower inlet 10 on the side near the lower water inlet 9. The lower inlet 10 is connected to the lower water inlet 9. The housing 6 has a top water outlet 11 on the top. The water pump motor 12 is located below the top water outlet 11.
[0034] The water pump motor is located between the propulsion motor 2 and the filter box 4.
[0035] Working principle:
[0036] When the pool cleaning machine moves on the water surface, the baffle 13 is opened, and the water passes through the upper inlet 7, the upper outlet 8, the filter box 4, the propulsion motor 2, and the propulsion impeller 1 in sequence. After flowing through the rotating propulsion impeller 1, it is discharged into the pool from the upper outlet 3. Thus, the propulsion device that sprays water backward can both drive the cleaning machine to move and assist in drainage, increase the outflow rate and speed of the filtered water, and improve the filtration efficiency.
[0037] When the pool cleaning machine moves underwater, the water flows through the lower inlet 9, the lower outlet 10, the filter box 4, the water pump motor 12, and the water pump impeller 14 in sequence. After flowing through the rotating water pump impeller 14, the water is discharged into the pool from the top outlet 11. At the same time, the lower roller brush 15 cleans the bottom or walls of the pool. In this way, the pool cleaning machine can clean the bottom or walls of the pool underwater, as well as clean the surface of the water.
[0038] The existing technology generally uses snorkeling technology to switch pool cleaning machines from underwater to above-water operation, which is a well-known technical method and will not be described in detail here.
[0039] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
