[0018] Embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. In the drawings, the same or similar components are denoted by the same reference numerals, and their descriptions will not be repeated.

[0019] When cleaning the pool wall, for example, the pool wall at the water line, a portion of the pool automatic cleaning device can need to leave the water surface in order to completely clean the side wall. When the pool automatic cleaning device re-enters the water and continues cleaning, the air previously entering the inside of the pool automatic cleaning device can not be quickly discharged, thereby increasing unnecessary buoyancy and possibly causing the posture of the pool automatic cleaning device in the water to become unstable, which in turn can affect the subsequent cleaning operation.

[0020] In some embodiments, one or more exhaust holes can be configured at the front end of the pool automatic cleaning device, so that when the pool automatic cleaning device re-enters the water, the air inside is quickly discharged through the exhaust holes. In the case of too few or too small exhaust holes, the air discharge efficiency can be affected. In the case of a large number of exhaust holes, the water absorption capacity of the pool automatic cleaning device can be reduced and the cleaning effect of the pool automatic cleaning device can be affected. In addition, in the case of a large number of exhaust holes, the garbage in the water can also enter the non-filtering mechanism part inside the pool automatic cleaning device along with the pool water, which can affect the normal work of other components inside the pool automatic cleaning device.

[0021] Therefore, in some embodiments, an exhaust cover can be provided for the exhaust port, so that the exhaust cover can automatically open the exhaust port as the automatic cleaning device of the pool moves backward into the water, and can also automatically close the exhaust port when the automatic cleaning device of the pool is submerged in water.

[0022] like Figure 1 As shown, an exhaust port 120 is provided on the housing 110 of the automatic sink cleaning device 100. For example, the exhaust port 120 can be configured on the front housing of the automatic sink cleaning device 100, such as at the junction of the front and bottom of the automatic sink cleaning device 100. The exhaust port 120 connects the interior and exterior of the automatic sink cleaning device 100, allowing air inside the automatic sink cleaning device 100 to be discharged to the exterior through the exhaust port 120.

[0023] like Figure 1 As shown, an exhaust cover 130 is also provided at the exhaust port 120. The exhaust cover 130 is hinged to the housing 100, or connected to the housing 100 in any other way that allows the exhaust cover 130 to rotate relative to the housing 100 and open or close the exhaust port 120.

[0024] like Figure 2 As shown, the vent cover 130 can be configured to automatically open the vent 120 as the automatic pool cleaning device 100 reverses into the water. For example, the vent 120 may be positioned at the front of the automatic pool cleaning device 100, protruding from the pool surface. Figure 2 The shadow plane in the image) and the automatic pool cleaning device 100 is in a vertical posture (including a near-vertical posture and a posture that can be considered vertical) as shown in the image. Figure 2 As the water flows backwards below the surface of the pool as indicated by the arrow, the amount of water entering the automatic pool cleaning device 100 from the pool through the inlet or gap increases, causing the pressure of the air remaining inside the automatic pool cleaning device 100 to increase. This increases the pressure of the air, which overcomes resistance such as the weight of the vent cover 130 and pushes open the vent cover 130, allowing the air remaining inside the automatic pool cleaning device 100 to be quickly discharged to the outside of the automatic pool cleaning device 100 through the vent 120.

[0025] Additionally, the vent cap 130 can also be configured to automatically close the vent 120 when the automatic pool cleaning device 100 is submerged in water. For example, as Figure 3 As shown, the automatic water cleaning device 100 is completely submerged in a vertical position on the surface of the water tank. Figure 3When the water in the pool is sucked into the inside of the pool automatic cleaning device 100 under the condition that the water level in the pool is below the shadow plane (as shown in the figure), the water in the pool can be sucked into the inside of the pool automatic cleaning device 100 under the action of the water pump (not shown) in the pool automatic cleaning device 100, so that the exhaust cover 130 can fall down and close the exhaust port 120 under the action of the suction force. In this way, for example, the internal suction force of the pool automatic cleaning device 100 can be prevented from being reduced, and at the same time, the garbage in the water can be prevented from entering the non-filtering mechanism part of the pool automatic cleaning device 100 from the exhaust port 120 along with the pool water.

[0026] In one or more embodiments, as shown in Figure 4 At least one elastic component 300 such as a spring can be arranged between the housing 110 and the inner side of the exhaust cover 130 to connect the housing 110 and the exhaust cover 130. In this way, the exhaust cover 130 can be closed by the contraction force of the elastic component 300. The material and method for making the elastic component 300 can be appropriately selected, so that during the process of the pool automatic cleaning device 100 retreating below the surface of the pool in a vertical posture, the pressure of the air remaining in the inside of the pool automatic cleaning device 100 is sufficient to overcome the resistance such as the contraction force of the elastic component 300 and the self-gravity of the exhaust cover 130, and to push open the exhaust cover 130.

[0027] When the pool automatic cleaning device 100 is completely submerged in water, the exhaust cover 130 can quickly fall down under the action of the contraction force of the elastic component 300, so as to quickly close the exhaust port 120. In this way, the internal suction force of the pool automatic cleaning device 100 can be timely prevented from being reduced, and the garbage in the water can be quickly prevented from entering the non-filtering mechanism part of the pool automatic cleaning device 100 from the exhaust port 120 along with the pool water.

[0028] In one or more embodiments, as shown in Figure 4 The exhaust port 120 can be configured as a mesh or grid structure with at least one opening 310. Correspondingly, at least one protruding part 320 can be provided on the inner side of the exhaust cover 130. The at least one protruding part 320 can engage with at least part of the at least one opening 310 in the state that the exhaust cover 130 closes the exhaust port 120. In this way, the exhaust cover 130 can be prevented from sinking into the exhaust port 120, and a better sealing effect can also be obtained, and in addition, the garbage in the water can also be partially prevented from entering the inside of the pool automatic cleaning device 100 from the exhaust port 120.

[0029] In one or more embodiments, as shown in Figure 4As shown, the edge of the exhaust port 120 can be provided with a containing groove 330, so that the exhaust cover 130 can be at least partially contained in the containing groove 330 in the state of closing the exhaust port 120. For example, a limiting support surface 340 can be provided in the containing groove 330, so that the limiting support surface 340 limits and supports the exhaust cover 130 in the state of the exhaust cover 130 being at least partially contained in the containing groove 330. Thus, it is possible to prevent the exhaust cover 130 from sinking into the exhaust port 120.

[0030] In one or more embodiments, as shown, the outer shape of the exhaust cover 130 can be configured to form a continuous and complete area with the outer surface of the housing 110 in the state of the exhaust cover 130 being contained in the containing groove 330. Thus, it is possible to make the water tank automatic cleaning device 100 more beautiful. Figure 3
