Description

Cleaning equipment This application claims priority to Chinese Patent Application No. 202422616161.5, filed on October 28, 2024, entitled "Cleaning Equipment", the entire contents of which are incorporated herein by reference. Technical Field This application relates to the field of cleaning robots, specifically a cleaning device. Background Technology Current underwater cleaning equipment has a bottom cleaning function and can collect underwater debris. However, in related technologies, during the sinking process after the cleaning equipment enters the water, there is a problem that the air inside the equipment is difficult to expel, resulting in a slow sinking speed. Summary of the Invention Therefore, it is necessary to provide a cleaning device that can increase the sinking speed after entering the water. One embodiment of this application provides a cleaning device, including a device body and a first vent. A first cavity is formed inside the device body. The first vent is located on the device body near its top, communicates with the first cavity, and is located at the end furthest from the center of gravity of the cleaning device. The first vent is used to discharge gas from the first cavity to the outside atmosphere. When the cleaning device performs underwater cleaning, the end of the cleaning device where the center of gravity is located is submerged in the water, while the end furthest from the center of gravity is tilted upwards relative to the water surface. The gas in the first cavity is discharged to the outside atmosphere through the first vent. In the cleaning device provided in this application, the first vent is located near the top of the main body of the device and at the end of the device away from the center of gravity. This causes the end of the cleaning device at the center of gravity to sink faster than the end away from the center of gravity when cleaning underwater. As a result, the end of the cleaning device away from the center of gravity tilts upward relative to the water surface. Consequently, the gas in the cleaning device will naturally gather at the first vent and be discharged to the outside atmosphere through the first through hole, thereby accelerating the water intake of the first cavity and thus speeding up the sinking speed of the cleaning device. In some embodiments, a first shield is rotatably connected to the main body of the device, the first shield being located at the first vent to open or close the first vent. In some embodiments, the cleaning device further includes a water pump assembly located inside a first cavity, and a first shielding member located outside the first cavity. When the water pump assembly is started, a negative pressure is generated inside the first cavity to attract and press the first shielding member against the first air outlet. In some embodiments, the first shielding member is a flexible silicone sheet. When the gas in the first cavity flows and gathers toward the first vent, the first shielding member can open the first vent under the action of the flowing gas. In some embodiments, the main body of the device further includes a second cavity, which is located at the end away from the center of gravity of the cleaning device and adjacent to the first cavity. A second vent is provided on the top wall of the second cavity, which communicates with the outside atmosphere. The first cavity and the second cavity are connected through the first vent. In some embodiments, the cleaning device further includes a drain hole located on the device body and near its bottom. The drain hole communicates with the first cavity and is located at an end away from the center of gravity of the cleaning device. When the cleaning device is lifted out of the water, the water in the first cavity is discharged through the drain hole. In some embodiments, a second shield is rotatably connected to the main body of the device, the second shield being located at the drain hole for opening or closing the drain hole. In some embodiments, the cleaning device also includes a handle, which is located on the main body of the device and at one end near the center of gravity of the cleaning device. In some embodiments, the cleaning device further includes a buffer element disposed on the main body of the device and located at one end away from the center of gravity of the cleaning device, with the buffer element facing the drain hole and spaced at a predetermined distance. In some embodiments, a through hole is provided on the bottom wall of the second cavity, and the through hole communicates with the outside atmosphere.
