[0021] Specific descriptions are made for the preferred embodiments provided by the present utility model according to the accompanying drawings.

[0022] The present utility model provides a snorkeling device for a pool robot, including at least one floating bin 10 for storing water or gas. The inner cavity of the floating bin 10 is communicated with a water inlet / outlet 11 for water inlet and outlet and a ventilation port 12 for communicating with the air above the water surface. The opening of the ventilation pipe communicated with the ventilation port 12 is above the water surface, and the water inlet / outlet is below the water surface when the pool robot floats or dives; each water inlet / outlet 11 is communicated with a water inlet / outlet power device 20 for controlling the on / off of the water path in the floating bin. The water inlet / outlet power device 20 is connected with a main control module for controlling the operation of the water inlet / outlet power device according to requirements; the entire snorkeling device is placed in the housing of the robot. The water inlet and outlet in the floating bin 10 are controlled by the water inlet / outlet power device 20 to adjust the proportion of water and air in the floating bin 10, change the specific gravity of the entire robot, thereby adjusting the draft depth of the robot, driving the entire robot to float on the water surface or sink underwater, and simultaneously meeting the user's needs for cleaning the pool water surface and underwater, bringing convenience to the user.

[0023] According to the buoyancy formula, F buoy = ρ liquid gV displacement, where ρ liquid represents the density of the liquid, with the unit of kg / m³; g represents a constant, g = 9.8 N / kg; V displacement represents the volume of the displaced liquid, with the unit of m³. The magnitude of the buoyancy force exerted on an object in a liquid depends only on the volume of the object immersed in the liquid and the density of the liquid, and is independent of factors such as the density of the object itself, its motion state, and the depth of immersion in the liquid. Controlling the water inlet and outlet in the floating bin 10 by the water inlet / outlet power device 20 is to control the volume of V displacement. When F buoy is greater than the gravity, the floating bin 10 floats on the water surface. When F buoy is less than the gravity, the floating bin 10 sinks in the water; when the snorkeling device is initially placed in the water, since the generated buoyancy force is greater than the overall gravity of the snorkeling device in the initial state, the floating bin 10 floats on the water surface; when the snorkeling device is placed in the robot, due to the gravity of the robot, when the entire robot floats in the water, a preset draft position will be formed on the housing of the robot and the floating bin, that is, a floating state draft line is formed in the floating bin.

[0024] To ensure that when the floating bin 10 is submerged in water or floating on the water surface, the floating bin 10 still maintains air circulation with the air above the water surface, a ventilation pipe is connected to the ventilation opening 12 on the floating bin 10, and the opening of the ventilation pipe remains above the water surface. Generally, the ventilation opening 12 is arranged at the top of the floating bin 10. The ventilation pipes connected to the ventilation openings 12 of each floating bin 10 can be independent of each other, and the openings of each ventilation pipe are above the water surface; the ventilation openings 12 of each floating bin 10 can also be connected as a whole through a ventilation pipe to save space, and the opening of the ventilation pipe is above the water surface.

[0025] The ventilation pipe is connected to a float 30 floating on the water surface, and the float 30 is provided with an air hole 31 communicated with the ventilation pipe. A hollow pipe 32 is arranged below the float 30, and the hollow pipe 32 is communicated with the ventilation pipe of the floating bin and the air hole 31. Generally, the ventilation openings 12 of each floating bin 10 are directly in fluid communication with the air above the water surface through the ventilation pipe. When water enters the inner cavity of the floating bin, air is automatically squeezed out from the inner cavity, and when the inner cavity of the floating bin drains water, air will automatically enter the inner cavity.

[0026] To facilitate the injection of water into the floating bin 10 at any time when it is in the floating state, the water inlet 11 of the floating bin 10 is always below the water surface, that is, the water inlet 11 of the floating bin 10 is below the waterline of the floating bin in the floating state. Generally, the water inlet 11 of the floating bin 10 is arranged at the bottom of the floating bin; and for the convenience of connection, the water inlet 11 of the floating bin is connected with a water pipe, so that the opening of the water pipe is below the waterline of the floating bin 10 in the floating state.

[0027] When the entire submersible device is placed inside the robot, to ensure the normal operation of the water inlet and outlet power device 20, the water inlet and outlet power device 20 is generally placed inside a sealed bin 40, and the water pipe connected to the water inlet and outlet power device 20 passes through the sealed bin 40, and the opening of the water pipe is below the water surface, ensuring that water can be injected into the floating bin 10 through the water inlet and outlet power device 20.

[0028] As Figure 1 shown, as the first preferred embodiment of the submersible device for a pool robot provided by the present invention, in this embodiment, the water inlets 11 of each floating bin 10 are connected as a whole through a water pipe, the water pipe is connected with a water inlet and outlet power device 20, and the water inlet and outlet power device 20 is used to control the water inlet and outlet of each floating bin 10. The water inlet and outlet power device 20 can be a peristaltic pump or other pump bodies that can realize water inlet and outlet control.

[0029] Taking the water inlet and outlet power device 20 as a peristaltic pump as an example, the peristaltic pump is located inside the sealed chamber 40. The opening of the water pipe connected to the peristaltic pump passes through the sealed chamber 40 and is below the floating draft line of the floating chamber. The peristaltic pump rotates counterclockwise to inject water into the floating chamber 10 and rotates clockwise to discharge the water in the floating chamber 10. When the robot needs to work underwater, the peristaltic pump rotates counterclockwise, and the water in the swimming pool is pressed into the floating chamber 10 by the work of the peristaltic pump. The air in the floating chamber 10 is discharged through the air holes 31 on the float 30 via the air vent 12 due to the filling of water. When the floating chamber 10 is filled with water, the robot will sink to the bottom due to the change in specific gravity. When the robot needs to float to the water surface, the peristaltic pump rotates clockwise to discharge the water in the floating chamber 10, and air is supplemented into the floating chamber 10 through the air holes 31 on the float and the air vent 12. Since the water in the floating chamber 10 is emptied, the specific gravity of the machine is less than that of water, and the buoyancy generated by the water will lift the robot to the water surface and keep it at the preset draft position.

[0030] As the second preferred embodiment of the snorkeling device for a pool robot provided by the present utility model, the difference between the second preferred embodiment and the first preferred embodiment is that the water inlet and outlet power device 20 includes a water inlet power driver 21 for controlling the on-off of the water inlet waterway and a drainage power driver 22 for controlling the on-off of the water outlet waterway. The water inlet pipeline in the water pipe is connected to the water inlet power driver 21, and the water outlet pipeline in the water pipe is connected to the drainage power driver 22. The opening of the pipeline connected to the water inlet power driver 21 and the opening of the pipeline connected to the drainage power driver 22 are both outside the sealed chamber 40. The water inlet into the floating chamber 10 is controlled by the water inlet power driver 21, and the water outlet from the floating chamber 10 is controlled by the drainage power driver 22. When the robot needs to work underwater, the water inlet power driver 21 is activated, and the water in the swimming pool is pressed into the floating chamber 10 by the water inlet power driver 21. The air in the floating chamber 10 is discharged through the air holes 31 on the float 30 via the air vent 12. When the floating chamber 10 is filled with water, the robot will sink to the bottom due to the change in specific gravity. When the robot needs to float to the water surface, the drainage power driver 22 is activated to discharge the water in the floating chamber 10, and air is supplemented into the floating chamber 10 through the air holes 31 on the float and the air vent 12. Since the water in the floating chamber 10 is emptied, the specific gravity of the machine is less than that of water, and the buoyancy generated by the water will lift the robot to the water surface and keep it at the preset draft position.

[0031] The water inlets 11 of the floating chambers 10 are connected as a whole through a water pipe, and the water pipe is connected to a tee. One end of the tee forms a water inlet pipeline, the water inlet pipeline is connected to a water inlet power driver 21, the other end of the tee forms a water outlet pipeline, and the water outlet pipeline is connected to a drainage power driver 22. As Figure 2 shown, as the first embodiment, the water inlet power driver 21 can be a solenoid valve, and the drainage power driver 22 is a water pump that can drain water, such as a diaphragm pump, and the water pump has a check valve function; asFigure 3 As shown, as a second embodiment, both the water inlet power driver 21 and the drain power driver can be water pumps, such as diaphragm pumps, which have a check valve function.

[0032] As Figure 4 As shown, as a third preferred embodiment of the snorkeling device for a pool robot provided by the present utility model, the difference between the third preferred embodiment and the second preferred embodiment is that the water passing ports 11 of the respective floating bins 10 are connected into one body through a water passing pipeline, and the water passing pipeline is connected in series with the water inlet power driver 21 and the drain power driver 22, and the pipe opening communicating with the drain power driver 22 is outside the sealed bin 40; the water inlet power driver 21 is a solenoid valve, and the drain power driver 22 is a water pump, a centrifugal pump, an axial flow pump or other water pumps. When the drain power driver 22 is not working, water flow is allowed to pass through.

[0033] For example, the water inlet power driver 21 is a solenoid valve, and the drain power driver 22 is a water pump; when the robot needs to work underwater, the main control module in the robot controls the solenoid valve to open. Under the action of atmospheric pressure, the water in the pool will enter from the water outlet of the water pump, pass through the pump body and the solenoid valve, and enter the floating bin 10. The air in the floating bin 10 is discharged from the ventilation port 12 through the air holes 31 on the float 30. After the floating bin 10 is filled with water, the robot will sink to the bottom due to the change in specific gravity; when the robot needs to float to the water surface, the main control module in the robot controls the solenoid valve to open and at the same time turns on the water pump for drainage. At this time, the water in the floating bin 10 will be discharged from the water outlet of the water pump under the action of the water pump's work; when the water pump is draining water, a negative pressure is formed in the inner cavity of the floating bin 10, and air is supplemented into the inside of the floating bin 10 through the air holes 31 on the float and the ventilation port 12. Since the water in the floating bin 10 is emptied, the specific gravity of the machine is less than that of water, and the buoyancy generated by the water will lift the robot to the water surface and keep it at the preset draft position; when the water in the floating bin 10 is drained completely, the overall specific gravity of the machine returns to the floating state. At this time, the solenoid valve is closed, and then the water pump is turned off, and the machine enters the water surface working state.

[0034] The present utility model also provides a pool robot, including a housing. A snorkeling device for the pool robot is provided inside the housing. The main control module is used to control the operation of the water inlet and outlet power device 20 in the snorkeling device, adjust the ratio of water and air in the floating bin 10, change the counterweight of the floating bin 10, and adjust the draft depth of the entire robot, driving the entire robot to float on the water surface or sink underwater.

[0035] The present utility model also provides a snorkeling method for a pool robot. After the robot is turned on and placed in water, the main control module defaults to the underwater working mode. When the underwater work is completed, the main control module will control the robot to return to the water surface working mode. The main control module controls the water inlet and outlet power device 20 to fill or drain water into the floating bin 10. When water is filled into the floating bin 10, the air in the floating bin 10 is discharged through the ventilation port. When water is drained from the floating bin 10, the air on the water surface is injected into the floating bin through the ventilation port. The main control module has two working modes for controlling the robot to work underwater and on the water surface. When the robot reaches the preset working duration in the underwater working mode, it indicates that the underwater work is completed. When the robot is in the underwater working mode, a preset working duration will be set, generally 90 minutes or 120 minutes. When the robot reaches the preset working duration underwater, the main control module will control the machine to return to the water surface working mode. At this time, if the battery power in the robot is sufficient, the robot can immediately enter the water surface working mode when it returns to the water surface. If the power is insufficient, the robot will use the solar charging panel to charge solar energy on the water surface. After the charging reaches the preset level, the robot will enter the water surface working mode again.

[0036] As a preferred embodiment, as Figures 5 to 7 shown, there are 2 floating bins 10 in the pool robot. The water passing ports 11 in each floating bin 10 are connected through a water passing pipeline. An outlet power device 20 is provided on the pipeline. The outlet power device 20 is a peristaltic pump. The opening of the pipeline connected to the peristaltic pump is below the water line when the floating bin floats. After the robot is turned on and placed in water, the main control module defaults to the underwater working mode. The main control module controls the peristaltic pump in the snorkeling device to rotate counterclockwise. The water in the pool is pressed into the floating bin 10 by the work of the peristaltic pump. Due to the filling of water, the air in the floating bin 10 is discharged from the ventilation port 12 through the air holes 31 on the float 30. When the floating bin 10 is filled with water, the robot will sink to the bottom due to the change in specific gravity. When the underwater working mode of the robot is completed, the main control module will control the robot to switch to the water surface working mode. The main control module controls the peristaltic pump in the snorkeling device to rotate clockwise to drain the water in the floating bin 10. The air is supplemented into the floating bin through the air holes 31 on the float and the ventilation port 12. Since the water in the floating bin 10 is emptied, the specific gravity of the machine is less than that of water, and the buoyancy generated by the water will lift the robot to the water surface and keep it at the preset water line position.

[0037] In summary, the technical solution of the present utility model can fully and effectively achieve the above-mentioned utility model purpose, and the structure and functional principle of the present utility model have been fully verified in the embodiments, and can achieve the expected efficacy and purpose. Without departing from the principle and essence of the present utility model, various changes or modifications can be made to the embodiments of the utility model.
