Description

Technical Field

[0001] This utility model belongs to the field of cleaning equipment technology and relates to an underwater cleaning robot with rapid drainage function. Background Technology

[0002] With social development, in order to improve the comfort of the community or surrounding environment, facilities such as pools are often built in the area. However, pools also need to be cleaned and maintained frequently. Dust, insects, garbage and other debris falling into the water will greatly reduce the aesthetics of the pool. In order to better clean the bottom of the pool, there is a robot that can move underwater. Through the fan set inside the robot, water is sucked into the robot from the bottom, and garbage is intercepted inside. The filtered water is discharged from the top, thereby achieving the function of cleaning the bottom of the pool.

[0003] However, existing underwater cleaning robots also have some shortcomings. After the cleaning robot finishes cleaning, it needs to be taken out of the pool. Since the robot stores a lot of water inside, the water inside the robot cannot be drained quickly when it is first taken out of the water. You have to wait for the water to slowly flow out from the gaps. If you open the robot directly, it is easy to splash the user with water and also bring out the garbage inside, causing the garbage to spill outside, which reduces the convenience of using the robot. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the current technology by proposing an underwater cleaning robot with a rapid drainage function. The technical problem to be solved by this invention is: how to quickly drain the water from the robot when it is lifted out of the water.

[0005] The objective of this utility model can be achieved through the following technical solution: an underwater cleaning robot with rapid drainage function, comprising an upper shell and a lower shell, a storage cavity between the upper shell and the lower shell, a water inlet at the bottom of the lower shell, a rotatable fan blade at the top of the upper shell, a water outlet on the top side wall of the upper shell, and several drainage outlets at the bottom of the side wall of the lower shell, each drainage outlet being equipped with a covered filter screen and a baffle, the baffle being located on the outside of the lower shell, and the top of the baffle being rotatably connected to the lower shell.

[0006] In this solution, after the robot is submerged in water, the water fills the entire storage cavity. The internal fan blades start and rotate, creating a pressure difference within the storage cavity. Water flows upward from the bottom. Due to the reduced pressure at the bottom of the storage cavity, water is drawn in through the inlet, thus sucking in debris from the bottom of the pool. The debris remains in the storage cavity, while the filtered water is discharged from the outlet, effectively cleaning the bottom of the pool. Once the bottom is cleaned, the robot is removed from the pool. Simply tilting the robot to one side causes the baffle to rotate and separate from the outlet, quickly emptying the water from the storage cavity through the drain, significantly improving drainage efficiency. In this way, when the robot is working in water, the baffle fits snugly against the lower shell, closing the drain and ensuring that external water can only be drawn in through the inlet, increasing suction and cleaning efficiency. When the robot is removed for drainage, the filter screen at the outlet prevents debris collected in the storage cavity from escaping through the drain.

[0007] In the aforementioned underwater cleaning robot with rapid drainage function, a partition is provided on the top of the upper shell, and the fan blades are located at the partition. The bottom of the fan blades is connected to the storage cavity, and the sidewalls of the fan blades are connected to the water outlet. The partition divides the storage cavity into two parts. The fan blades draw in water from the bottom and push the water out from the side, creating a pressure difference within the storage cavity.

[0008] In the aforementioned underwater cleaning robot with rapid drainage function, a sealed motor chamber is provided at the bottom of the lower housing, and the top of the motor chamber is connected to the bottom of the fan blades. The motor chamber is used to house the motor, and the top of the motor chamber is connected to the fan blades, which can drive the rotation of the fan blades.

[0009] In the aforementioned underwater cleaning robot with rapid drainage function, a brush is provided at the bottom of the water inlet, and a soft rubber sheet that can flip into the storage cavity is provided at the top of the water inlet. The two ends of the brush and the soft rubber sheet are respectively fixed to the structure on the lower shell. The brush is used to scrape the bottom of the pool, making it easier to suck up the debris. The soft rubber sheet acts as an anti-backflow device and only opens when sucking into the storage cavity.

[0010] In the aforementioned underwater cleaning robot with rapid drainage function, the bottom of the lower housing is equipped with several rollers, the motor chamber is connected to the rollers, and the top of the upper housing is equipped with an integrally connected handle. The rollers are used to drive the robot to move in the water, and the handle makes it easy to lift the robot out of the water.

[0011] In the aforementioned underwater cleaning robot with rapid drainage function, the bottom of the brush is lower than the bottom of the roller, and a connecting frame is provided inside the lower housing. The brush being lower than the roller allows for better scraping of the pool bottom, while the connecting frame improves the robot's structural strength and prevents debris inside the storage chamber from moving upwards.

[0012] In the aforementioned underwater cleaning robot with rapid drainage function, several rotatable buckles are provided on the outer wall of the lower shell. These buckles can be flipped to engage with the upper shell, thus fixing the upper and lower shells together. The buckles are used to securely connect the lower and upper shells. After cleaning, when it is necessary to remove the collected waste from the storage cavity, the buckles can be flipped to separate the upper and lower shells, facilitating cleaning of the storage cavity.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. In this solution, after the bottom of the pool is cleaned, the robot is taken out of the pool. Simply tilt the robot to one side to make the baffle rotate and separate from the outlet, so that the water in the storage chamber can be quickly poured out from the drain, which greatly improves the drainage efficiency.

[0015] 2. In this solution, when the robot is working in water, the baffle fits against the lower shell to close the drain outlet, so that external water can only be drawn in through the inlet, making the suction at the inlet stronger and improving cleaning efficiency. When the robot is taken out to drain water, the filter screen on the outlet can filter the water and prevent the garbage collected in the storage chamber from escaping from the drain outlet.

[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] Example

[0022] like Figure 1As shown, an underwater cleaning robot with rapid drainage function includes an upper shell 1 and a lower shell 2. The upper shell 1 has handles 1b integrally connected on both sides of the top. The upper shell 1 has a water outlet 1a at the top. The lower shell 2 has rollers 2b at the bottom. The lower shell 2 has a rotatable buckle 2a. The buckle 2a can be flipped upwards and engaged with the upper shell 1 to fix the upper shell 1 and the lower shell 2 in place.

[0023] like Figure 2 As shown, a storage cavity 3 is provided between the upper housing 1 and the lower housing 2. A drain outlet 2c is provided below the side wall of the lower housing 2. A filter screen 2c2 with a cover and a baffle 2c1 are provided on the drain outlet 2c. The baffle 2c1 is located on the outside of the lower housing 2. The top of the baffle 2c1 is rotatably connected to the lower housing 2. A connecting frame 8 is provided inside the lower housing 2. A partition 6 is provided inside the upper housing 1. A fan blade 4 is provided inside the partition 6. The bottom of the fan blade 4 is connected to the storage cavity 3. The side of the fan blade 4 is connected to the water outlet 1a. A motor chamber 7 is provided inside the lower housing 2. The top of the motor chamber 7 is connected to the bottom of the fan blade 4.

[0024] like Figure 3 As shown, the bottom of the lower housing 2 is provided with a water inlet 5, the bottom of the water inlet 5 is provided with a brush 2d, and the top of the water inlet 5 is provided with a soft rubber sheet 5a that can be flipped into the storage cavity 3. The two ends of the brush 2d and the soft rubber sheet 5a are respectively fixed to the structure on the lower housing 2, and the bottom of the brush 2d is lower than the bottom of the roller 2b.

[0025] The working principle of this solution is as follows: Figure 1-3 As shown, after the robot is placed in the water, the water fills the storage cavity 3. The motor drives the fan blades 4 to rotate, creating a pressure difference inside the storage cavity 3. The water flows upward from the bottom of the storage cavity 3 and then flows out from the outlet 1a at the top. Due to the reduced pressure at the bottom of the storage cavity 3, water is drawn in from the inlet 5, which also sucks in the garbage at the bottom of the pool. The garbage is left in the storage cavity 3, while the filtered water is discharged from the outlet 1a, thus cleaning the bottom of the pool. After the bottom of the pool is cleaned, the robot is taken out of the pool and tilted to one side, causing the baffle 2c1 to rotate and separate from the outlet 1a. The water in the storage cavity 3 is filtered by the filter screen 2c2 and flows out quickly from the drain 2c, greatly improving the drainage efficiency. Then, the buckle 2a is flipped over to separate the upper shell 1 from the lower shell 2. Since the water in the storage cavity 3 has been basically drained, no water will leak out when the robot is opened, making it convenient to clean the inside of the storage cavity 3.
