Description

Technical Field

[0001] The present invention relates to the technical field of robots, and particularly to a pool robot. Background Art

[0002] With the continuous rise of the robot industry, pool cleaning robots have entered people's lives. A swimming pool is a venue for people to engage in swimming sports. Various garbage, floating objects, and suspended substances will appear during the use of the pool. Therefore, the pool needs to be cleaned regularly. Pool cleaning robots (including surface and underwater robots) can perform pool cleaning work, and they mainly carry cleaning mechanisms to move in the water. To ensure the cleaning effect, it is necessary to effectively improve the movement coverage rate and cleaning effect of the robot. The cleaning effect of the pool robot depends on the suction force and the traveling speed.

[0003] For existing pool robots, when the water spraying amount is too large, fine dust adsorbed on the bottom of the pool will be lifted during walking, and the ideal cleaning effect cannot be achieved. When the water spraying amount is reduced, the walking speed becomes slower and the cleaning time is prolonged.

[0004] The suction force is also closely related to the drainage volume and the flow rate, and all these performance parameters depend on the water channel cabin structure of the pool robot. In the existing water channel cabin design, the drainage volume of the pool robot is small, and the cleaning effect and cleaning speed are relatively slow. Summary of the Invention

Specific embodiments

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work shall fall within the protection scope of the present invention.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0029] The present invention effectively improves the cleaning ability and cleaning speed of the machine by adjusting factors such as the effective water outlet area of the water channel bin outlet, the number of guide plates, the size parameters of the guide plates, and the spacing. From the size of the outlet area, to the placement position and length of the guide vanes, the outlet area determines the flow rate and velocity, the placement of the guide vanes adjusts the direction of the velocity, and the size of the guide vanes affects the direction of the water spray and the traveling speed of the machine. The process of the present invention describes the test process and data, and the final test results effectively maintain the flow rate, flow volume, and traveling speed at a better effect.

[0030] Embodiment 1:

[0031] As shown in Figure 1-2 the figure, this embodiment includes a main body 2 provided with a water channel compartment 1. The water channel compartment 1 is provided with two drain ports 3. Six water guide plates are arranged in the drain ports 3 from left to right. The equal distribution of the six water guide plates makes the widths of the seven water outlets equal. It can also be understood that the water discharge volumes of the seven water outlets are equal. The length of the water guide plate is between 10.42 cm and 20.42 cm. This length of the water guide plate refers to the length of the water guide plate on the water outlet flow channel (along the water flow direction). The uniform distribution of the water guide plates can direct the water flow to the desired water spraying trajectory, concentrate the water flow in one place, and provide power for the movement of the machine.

[0032] In this embodiment, taking the original narrow opening as an example, when the motor is 7V, the power is 19.7W. At this time, the drainage volume is 61 L / min. When it is modified to a wide opening and the voltage is still 7V, the power is 19.6W at this time, which is almost the same as the power of the original narrow opening. However, the drainage volume is 88.5 at this time, and the drainage volume increases by 45%.

[0033] The drain port is enlarged to 50MM (for a traditional drain port, if only the drain port is enlarged without adding a water baffle, the water flow rate is too slow, resulting in the machine moving too slowly). Therefore, in this solution, the drain port can be increased to 50 mm. Because the drain port is enlarged, the number of water guide plates is set to 6 (for a traditional drain port, only 3 - 4 water guide plates can be set).

[0034] The six water guide plates are respectively a first water guide plate 301, a second water guide plate 302, a third water guide plate 303, a fourth water guide plate 304, a fifth water guide plate 305, and a sixth water guide plate 306. Among them, the first type of water guide plates includes the first water guide plate 301 and the sixth water guide plate 306, the second type of water guide plates includes the second water guide plate 302 and the fifth water guide plate 305, and the third type of water guide plates includes the third water guide plate 303 and the fourth water guide plate 304. The first type of water guide plates, the second type of water guide plates, and the third type of water guide plates are symmetrically arranged with respect to the drain port.

[0035] As shown in Figure 3 the figure, in this embodiment, the rear ends of the three types of water guide plates are flush with the rear end of the drain port. The lengths of the second water guide plate 302 and the fifth water guide plate 305 are equal to the cross-sectional width of the drain port. The front ends of the first water guide plate 301, the sixth water guide plate 306, the third water guide plate 303, and the fourth water guide plate 304 are recessed inward by 6 mm. By setting the lengths of the water guide plates in this way, the flow rate can be reduced, the flow volume can be increased, and the traveling speed can be moderate. At this time, the water flow rate is 2.36 m / s, and the drainage volume is 95 L / min. By cutting short the two sides of the two water guide plates, the water flow can be dispersed, the spraying force in the middle can be distributed to both sides, which plays a role in decelerating, and can increase the drainage volume and suction force.

[0036] The structure of the water channel cabin 1 can effectively increase the displacement and suction, and at the same time play a role in decelerating, so that the machine speed reaches the ideal state defined by the product, with strong suction, neither too fast nor too slow speed, and the cleaning effect and cleaning speed can be well improved.

[0037] In this embodiment, the water channel cabin 1 is a circular cabin body. The interior of the water channel cabin 1 is separated by an S-shaped partition 4 to form two flow channels 5. Two drain ports 3 are respectively connected to the two flow channels 5. This flow channel design can make the water flow through faster, effectively increasing the displacement.

[0038] As Figure 6 shown, in this embodiment, the water channel cabin 1 is provided with an upper cover 6. A partition sealing groove 7 is provided in the upper cover 6. The partition sealing groove 7 is adapted to the S-shaped partition 4. After the upper cover and the water channel cabin are installed, the S-shaped partition 4 will be embedded in the partition sealing groove 7, so as to separately seal the flow channel 5 and increase the sealing performance of the water channel cabin 1.

[0039] In this embodiment, the water channel cabin 1 and the upper cover 6 are connected by bolts.

[0040] In this embodiment, the outer peripheral side wall of the water channel cabin 1 is provided with equally spaced screw posts 8, which increases the sealing performance. Compared with the case where no screw posts are provided, the displacement can be increased by 5-6 L / min.

[0041] The water channel cabin structure of the present invention can effectively increase the displacement and suction, and at the same time play a role in decelerating, so that the machine speed reaches the ideal state defined by the product, with strong suction, neither too fast nor too slow speed, and the cleaning effect and cleaning speed of the pool robot can be well improved.

[0042] Embodiment 2:

[0043] This embodiment includes a main body 2 provided with a water channel cabin 1. The water channel cabin 1 is provided with two drain ports 3. Six water guide plates are arranged in the drain ports 3 from left to right. The equal distribution of the six water guide plates makes the widths of the seven water outlet ports equal, which can also be understood as the water discharge amounts of the seven water outlet ports are the same. The length of the water guide plate is between 10.42 cm and 20.42 cm. This length of the water guide plate refers to the length of the water guide plate on the water outlet flow channel (along the water flow direction). The equal distribution of the water guide plates can lead the water flow to the desired water spraying trajectory, concentrate the water flow in one place, and provide power for the movement of the machine.

[0044] The six water guide plates are respectively a first water guide plate 301, a second water guide plate 302, a third water guide plate 303, a fourth water guide plate 304, a fifth water guide plate 305 and a sixth water guide plate 306. Among them, the first type of water guide plate includes the first water guide plate 301 and the sixth water guide plate 306, the second type of water guide plate includes the second water guide plate 302 and the fifth water guide plate 305, and the third type of water guide plate includes the third water guide plate 303 and the fourth water guide plate 304. The first type of water guide plate, the second type of water guide plate and the third type of water guide plate are symmetrically arranged with respect to the drain outlet.

[0045] As Figure 4 shown, in this embodiment, the length of the third type of water guide plate is greater than the length of the second type of water guide plate, that is, the third water guide plate 303 and the fourth water guide plate 304 extend 4 mm into the main body of the water channel cabin. Through the above settings, the flow rate, flow volume and traveling speed of the pool robot in this embodiment can achieve the same effects as those in Embodiment 1.

[0046] The rest is the same as in Embodiment 1.

[0047] Embodiment 3:

[0048] This embodiment includes a main body 2 provided with a water channel cabin 1. The water channel cabin 1 is provided with two drain outlets 3. Six water guide plates are arranged in the drain outlets 3 from left to right. The six water guide plates are evenly distributed, so that the widths of the seven water outlets are also equal, or it can be understood that the water output of the seven water outlets is also equal. The length of the guide plate is between 10.42 cm and 20.42 cm. The length of this guide plate refers to the length of the guide plate on the water outlet channel (along the water flow direction). The even distribution of the guide plates can lead the water flow to the desired water spray trajectory, concentrate the water flow in one place, and provide power for the movement of the machine.

[0049] The six water guide plates are respectively a first water guide plate 301, a second water guide plate 302, a third water guide plate 303, a fourth water guide plate 304, a fifth water guide plate 305 and a sixth water guide plate 306. Among them, the first type of water guide plate includes the first water guide plate 301 and the sixth water guide plate 306, the second type of water guide plate includes the second water guide plate 302 and the fifth water guide plate 305, and the third type of water guide plate includes the third water guide plate 303 and the fourth water guide plate 304. The first type of water guide plate, the second type of water guide plate and the third type of water guide plate are symmetrically arranged with respect to the drain outlet.

[0050] As Figure 5As shown, in this embodiment, the length of the third type of water guide plate is equal to that of the second type of water guide plate. That is, the lengths of the third water guide plate 303 and the fourth water guide plate 304 are equal to those of the second water guide plate 302 and the fifth water guide plate 305. Through the setting of the water guide plates in this embodiment, the flow rate of the pool robot can be reduced and the flow volume can be increased, and the machine moves in a left turn and circles. Because the pool robot has no driving wheels, it circles in one direction all the time and slowly cleans from the outer circle to the inner circle in a spiral shape, which can also be used as a cleaning method.

[0051] The rest is the same as in Embodiment 1.

[0052] Those skilled in the art can make various modifications and variations to the present invention. If these modifications and variations are within the scope of the claims of the present invention and their equivalent technologies, then these modifications and variations are also within the protection scope of the present invention.
