Description

Technical Field

[0001] The utility model relates to the technical field of window cleaning robots, and particularly relates to a window cleaning robot. Background Art

[0002] Existing window cleaning robots often adopt a design with double nozzles, that is, water outlets at both ends, to ensure water output, wet the cleaning cloth, and ensure the window cleaning effect. However, when the window cleaning robot works in the vertical direction, that is, when cleaning the window in an N shape, due to the water outlets at both ends of the window cleaning robot, gas can enter the water tank from above, increasing the air pressure in the water tank. Coupled with the fact that when moving in an N shape, all the water in the entire water tank compartment is concentrated downward, and the water pressure is also greater, resulting in water leakage when the ceramic piece on the atomizing sheet vibrates.

[0029] The following embodiments are used to illustrate the present utility model, but the present utility model is not limited by these embodiments. Modifying the specific embodiments of the present utility model or making equivalent replacements for some technical features without departing from the spirit of the present utility model scheme shall all be covered within the scope of the technical solution claimed by the present utility model.

[0030] As Figures 1-13 , a window cleaning robot includes a window cleaning robot body 1. A water tank 2 is provided inside the window cleaning robot body 1. A water containing cavity 21 is formed inside the water tank 2. A water separating plate 3 and balls 6 are provided inside the water containing cavity 21. The water containing cavity 21 is separated by the water separating plate 3 to form a first chamber 4 and a second chamber 5. A first water outlet end and a second water outlet end are provided on the water containing cavity 21. The first water outlet end is communicated with the first chamber 4, and the second water outlet end is communicated with the second chamber 5. A water passing hole 31 is provided on the water separating plate 3. The ball 6 is arranged near the water passing hole 31. The ball 6 is used to open or close the water passing hole 31 to communicate or cut off the first chamber 4 and the second chamber 5.

[0031] The present utility model provides a window cleaning robot. The water containing cavity 21 has a first water outlet end and a second water outlet end, that is, the water in the water containing cavity 21 can flow out from the first water outlet end through the first chamber 4 and / or from the second water outlet end through the second chamber 5. A water separating plate 3 and balls 6 are provided inside the water containing cavity 21. The water passing hole 31 on the water separating plate 3 can be closed by the balls 6 to cut off the first chamber 4 and the second chamber 5; or the water passing hole 31 on the water separating plate 3 can be opened by the balls 6 to communicate the first chamber 4 and the second chamber 5.

[0032] The window cleaning robot generally has a state of cleaning the window in the vertical direction and a working state of cleaning the window in the left - right direction. When the window cleaning robot works in the vertical direction, the water passing hole is closed and cut off by the balls to ensure that the water in the first chamber can flow out from the first water outlet end while preventing the water from flowing out from the second water outlet end of the second chamber, thus avoiding water leakage. When the window cleaning robot works in the left - right direction, the balls open the water passing hole, enabling the water in the water tank to flow out from the first water outlet end of the first chamber and the second water outlet end of the second chamber, ensuring the outflow of the water in the water tank and wetting the cleaning cloth over the largest area.

[0033] The provided water separating plate and water passing hole can meet the water outlet requirements of different working states of the window cleaning robot.

[0034] When the window cleaning robot works in an "N" - shaped pattern to clean the window, as Figures 5-6, that is, when the window cleaning robot performs window cleaning work in the up and down direction, the window cleaning robot is adjusted to the state of working in the up and down direction. At this time, the first chamber 4 is in the downward position, and the second chamber 5 is at the upper end position of the first chamber 4. The ball 6 closes the water passing hole 31, and the water in the water storage chamber 21 can flow out from the first water outlet end of the first chamber 4. And because the second chamber 5 is arranged in the vertical direction, the water in the water storage chamber 21 gathers downward, so the water will not flow out from the second water outlet end of the second chamber 5. While ensuring that the water can flow out smoothly when the window cleaning robot is in the "N" - shaped working state, it avoids the situation of water leakage caused by the water flowing out from the first water outlet end of the first chamber 4.

[0035] When the window cleaning robot performs window cleaning in a "Z" - shaped pattern, as Figures 3-4 , that is, when the window cleaning robot performs window cleaning work in the left - right direction, the window cleaning robot is adjusted to the state of working in the left - right direction. At this time, the first chamber 4 is in the right - hand position, and the second chamber 5 is in the left - hand position. The ball 6 opens the water passing hole 31, then the first chamber 4 and the second chamber 5 are in communication with each other. When the window cleaning robot is working, it can ensure that the water can flow out from the first water outlet end of the first chamber 4 and also from the second water outlet end of the second chamber 5, ensuring the water outflow situation when the window cleaning robot performs window cleaning in a "Z" - shaped pattern.

[0036] Inside the water storage chamber 21 and near the water passing hole 31, a baffle assembly 7 is provided. An installation space 70 is formed between the baffle assembly 7 and the top wall and the bottom wall of the water tank 2. The ball 6 is movably arranged in the installation space 70.

[0037] The water tank 2 includes a water tank upper cover 22 and a water tank lower cover 23. The water tank upper cover 22 covers the water tank lower cover 23 to form the water storage chamber 21 between the water tank upper cover 22 and the water tank lower cover 23. And at the water tank upper cover 22 and at the installation space 70, a groove 221 is provided.

[0038] In this embodiment, the window cleaning robot includes a bottom shell 100. The water tank upper cover 22 is arranged at one end far from the bottom shell 100, then the water tank lower cover 23 is arranged at one end close to the bottom shell 100.

[0039] In this embodiment, a water filling port is provided on the window cleaning robot body 1. The water filling port is communicated with the first chamber 4. The water filling port is arranged on the water tank lower cover 23.

[0040] When the window cleaning robot needs to be filled with water, place the window cleaning robot on the table. The window cleaning robot can be placed flat on the table with the bottom shell 100 facing the table (downward) and the water tank lower cover 23 facing the sky direction (upward). Add water to the water storage chamber 21 through the water filling port. At this time, because the ball 6 will be arranged in the groove 221 due to being placed flat, asFigure 7 , there is no closed water passing hole 31, enabling the first chamber 4 and the second chamber 5 to communicate. At this time, when water is added to the water filling port, the water enters the first chamber 4 and can flow from the first chamber 4 into the second chamber 5 through the water hole 31. The first chamber 4 and the second chamber 5 can be filled with water smoothly.

[0041] In this embodiment, the water separation plate 3 includes a first water separation plate 32 and a second water separation plate 33. The first water separation plate 32 is at one end of the upper cover 22 of the water tank, and the second water separation plate 33 is at one end of the lower cover 23 of the water tank. When the upper cover 22 of the water tank is covered on the lower cover 23 of the water tank, the water passing hole 31 is formed between the first water separation plate 32 and the second water separation plate 33.

[0042] The baffle assembly 7 includes a first baffle 71. The first baffle 71 is disposed opposite to the water separation plate 3. The ball 6 can move between the first baffle 71 and the water separation plate 3, and the movement distance of the ball 6 in the direction away from the water separation plate 3 is restricted by the first baffle 71. The setting of the first baffle 71 can prevent the ball 6 from moving too far in the direction away from the water separation plate 3.

[0043] The baffle assembly 7 includes a second baffle 72 and a third baffle 73. The second baffle 72 and the third baffle 73 are between the water separation plate 3 and the first baffle 71 to form a passing channel between the second baffle 72 and the third baffle 73, so as to guide the movement of the ball 6 in the installation space 70 through the second baffle 72 and the third baffle 73.

[0044] In this embodiment, one end of the second baffle 72 is connected to the edge of one end of the water passing hole 31 and extends in the direction of the first baffle 71; one end of the third baffle 73 is connected to the edge of the other end of the water passing hole 31 and extends in the direction of the first baffle 71.

[0045] When the window cleaning robot works in an "N" shape to clean the window, that is, when the window cleaning robot cleans the window in the up and down direction, the left and right direction movement of the ball 6 is restricted by the second baffle 72 and the third baffle 73; when the window cleaning robot works in a "Z" shape to clean the window, that is, when the window cleaning robot cleans the window in the left and right direction, the up and down direction movement of the ball 6 is restricted by the second baffle 72 and the third baffle 73.

[0046] In this embodiment, the installation space 70 is formed between the first baffle 71, the second baffle 72, the third baffle 73, the upper cover of the water tank 2, and the lower cover of the water tank 2.

[0047] One end of the third baffle 73 close to the installation space 70 forms an inclined slope, which is inclined towards the water passing hole 31 from the end close to the first baffle 71 to the end close to the water separation plate 3. When the ball 6 moves towards the water separation plate, the inclined slope helps to guide the ball 6 towards the water passing hole 31, ensuring the closing effect of the ball 6 on the water passing hole 31.

[0048] It further includes a guide plate 8. One end of the guide plate 8 is connected to the top wall or the bottom wall of the installation space 70, and the other end of the guide plate 8 is connected to the water separation plate 3. A guide slope is formed at the guide plate 8, and the guide slope is used to guide the ball 6 towards the water passing hole 31.

[0049] In this embodiment, the guide plate 8 includes a first guide plate 81 and a second guide plate 82. A first inclined slope is formed at the first guide plate 81. One end of the first inclined slope is connected to the upper cover 22 of the water tank, and the other end is connected to the water separation plate 3. The first inclined slope extends obliquely towards the water passing hole 31 from the end close to the upper cover 22 of the water tank to the end close to the water separation plate 3.

[0050] A second inclined slope is formed at the second guide plate 82. One end of the second inclined slope is connected to the lower cover 23 of the water tank, and the other end is connected to the water separation plate 3. The second inclined slope extends obliquely towards the water passing hole 31 from the end close to the lower cover 23 of the water tank to the end close to the water separation plate 3. So when the ball 6 approaches the water separation plate 3, the ball 6 is guided towards the water passing hole 31 to ensure the closing of the water passing hole 31 by the ball 6.

[0051] It further includes a first atomization assembly 91 and a first water outlet pipe 92. A first water outlet 95 and a second water outlet 96 are provided on the water containing cavity 21 and close to the first water outlet end.
