Cleaning equipment

Abstract

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 with its center of gravity submerges in the water. The sinking speed of this end is faster than that of the end furthest from the center of gravity. The end furthest from the center of gravity is tilted upwards relative to the water surface. Therefore, the gas in the cleaning device naturally gathers towards the first vent and is discharged to the outside atmosphere through the first vent, thereby accelerating the water intake of the first cavity and thus speeding up the sinking speed of the cleaning device.

Description

Technical Field

[0001] This application relates to the field of cleaning robots, specifically a cleaning device. Background Technology

[0002] 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. Utility Model Content

[0003] Therefore, it is necessary to provide a cleaning device that can increase the sinking speed after entering the water.

[0004] 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.

[0005] 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.

[0006] 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 hole for opening or closing the first vent hole.

[0007] 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.

[0008] 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.

[0009] 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.

[0010] 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.

[0011] 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.

[0012] 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.

[0013] 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.

[0014] 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. Attached Figure Description

[0024] The technical solution of this application will now be described with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments.

[0025] It should be noted that when a component is referred to as being "located on" or "connected to" another component, it can be directly on the other component or it can be located in an intermediate component. The terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "above" includes directly above and diagonally above, or simply indicates a higher horizontal level; the term "below" includes directly below and diagonally below, or simply indicates a lower horizontal level. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application.

[0026] 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.

[0027] In view of this, it is necessary to provide a cleaning device capable of increasing the sinking speed after entering the water. The cleaning device includes a main body and a first vent, with a first cavity formed inside the main body. The first vent is located on the main body near its top, communicates with the first cavity, and is located at the end away from the center of gravity of the cleaning device. The first vent is used to discharge the gas in the first cavity to the outside atmosphere. When the cleaning device is cleaning the bottom underwater, the end of the cleaning device with its center of gravity submerged in the water, while the end of the cleaning device away from its center of gravity tilts upward relative to the water surface, and the gas in the first cavity is discharged to the outside atmosphere through the first vent.

[0028] 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.

[0029] The following is in conjunction with the appendix Figures 1 to 7 This application provides a detailed description of some embodiments. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0030] Please see Figures 1 to 3 In one embodiment of this application, a cleaning device 100 is provided. The cleaning device 100 has an underwater cleaning mode. The cleaning device 100 in the underwater cleaning mode is used to sink to the bottom of the water and perform cleaning operations on the bottom of the water.

[0031] The cleaning device 100 includes a device body 10, and a first cavity 11 is formed inside the device body 10. The first cavity 11 is used to accommodate the internal components of the cleaning device 100. The device body 10 is provided with a first vent 12, which is located near the top of the device body 10. The first vent 12 communicates with the first cavity 11 and is located at the end away from the center of gravity of the cleaning device 100. The first vent 12 is used to discharge the gas in the first cavity 11 to the outside atmosphere.

[0032] When the cleaning device 100 performs underwater cleaning, the end of the cleaning device 100 with its center of gravity sinks faster than the end away from the center of gravity. This causes the end of the cleaning device 100 away from the center of gravity to tilt upwards relative to the water surface. As a result, the gas in the cleaning device 100 will naturally gather towards the first vent 12 and be discharged to the outside atmosphere through the first through hole 12. This accelerates the water intake of the first cavity 11, thereby speeding up the sinking speed of the cleaning device 100 and reducing the risk of gas remaining in the first cavity 11 and hindering the sinking of the cleaning device 100.

[0033] In some embodiments, the end where the center of gravity of the cleaning device 100 is located is the front end of the cleaning device 100, and the end of the cleaning device 100 away from the center of gravity is the rear end of the cleaning device 100. The first air outlet 12 is located at the rear end of the cleaning device 100 near the top.

[0034] In some embodiments, such as Figures 3 to 6As shown, a first blocking member 20 is rotatably connected to the main body 10 of the device. The first blocking member 20 is located at the first vent 12 and is used to open or close the first vent 12. Specifically, when the first blocking member 20 rotates toward the first vent 12 until it fits against the main body 10 of the device, the first blocking member 20 closes the first vent 12; when the first blocking member 20 rotates away from the first vent 12, the first vent 12 is opened.

[0035] In some embodiments, the cleaning device 100 further includes a water pump assembly 30, which is disposed on top of the cleaning device 100 and located within the first cavity 11. When the cleaning device 100 is submerged in water, the water pump assembly 30 is activated and exerts a downward force on the cleaning device 100, which helps to accelerate the sinking of the cleaning device 100. The first shielding member 20 is located outside the first cavity 11. When the water pump assembly 30 is activated, a negative pressure is generated in the first cavity 11. This negative pressure attracts the first shielding member 20, causing it to adhere tightly to the first vent 12, thereby closing the first vent 12. This reduces the risk of the first vent 12 dispersing the negative pressure generated by the water pump assembly 30. In other words, compared to when the first vent 12 is open, closing the first vent 12 allows the water pump assembly 30 to exert a greater force on the cleaning device 100, thus accelerating the sinking of the cleaning device 100.

[0036] In some embodiments, when the cleaning device 100 is in underwater cleaning mode, after the gas in the first cavity 11 flows and gathers toward the first vent 12, the first shield 20 will naturally open the first vent 12 under the pressure of the flowing gas, so that the gas in the first cavity 11 can be discharged to the outside atmosphere.

[0037] In some embodiments, the first shielding member 20 is a flexible silicone sheet. The flexible silicone sheet can better fit the edge of the first vent 12 to seal the first vent 12 under the negative pressure of the water pump assembly 30, and can also more easily open the first vent 12 under the gas pressure in the first cavity 11.

[0038] In some embodiments, the main body 10 of the device further includes a second cavity 13, which is located at the end away from the center of gravity of the cleaning device 100 and adjacent to the first cavity 11. A second vent 14 is provided on the top wall of the second cavity 13, communicating with the outside atmosphere. The first cavity 11 and the second cavity 13 are connected through a first vent 12. The second cavity 13 can accommodate a first shield 20 to protect it. When the cleaning device 100 is in underwater cleaning mode, the gas in the first cavity 11 first flows through the first vent 12 to the second cavity 13, and then is discharged to the outside atmosphere through the second vent 14.

[0039] In some embodiments, such as Figure 3 , Figure 4 and Figure 7 As shown, the cleaning device 100 is also provided with a drain hole 15 on the device body 10. The drain hole 15 is close to the bottom of the device body 10 and located at the end of the cleaning device 100 away from the center of gravity. The drain hole 15 is connected to the first cavity 11. When the cleaning device 100 is lifted out of the water, the water in the first cavity 11 is discharged through the drain hole 15 to reduce the weight of the cleaning device 100 and make it easier for the user to carry.

[0040] In some embodiments, a second blocking member 40 is rotatably connected to the main body 10 of the device. The second blocking member 40 is located at the drain hole 15 and disposed outside the first cavity 11, and is used to open or close the drain hole 15. Specifically, when the cleaning device 100 is lifted out of the water, the water in the first cavity 11 flows and gathers towards the drain hole 15. The second blocking member 40 will naturally open the drain hole 15 under the water pressure of the water in the first cavity 11, so as to drain the water in the first cavity 11.

[0041] Furthermore, when the water pump assembly 30 is started, the negative pressure generated in the first cavity 11 will attract the second shield 40, causing the second shield 40 to adhere tightly to the drain hole 15, thereby closing the drain hole 15. This reduces the risk of the drain hole 15 dispersing the negative pressure generated by the water pump assembly 30. In other words, compared to the case where the drain hole 15 is open, the closed drain hole 15 allows the water pump assembly 30 to exert a greater force on the cleaning equipment 100, thereby accelerating the sinking of the cleaning equipment 100.

[0042] In some embodiments, the second shield 40 is a flexible silicone sheet. The flexible silicone sheet can better fit the edge of the drain hole 15 to seal the drain hole 15 under the negative pressure of the water pump assembly 30, and can also more easily open the drain hole 15 under the water pressure of the water in the first cavity 11.

[0043] In some embodiments, the cleaning device 100 is further provided with a handle 50 on the device body 10. The handle 50 is used for a user to hold and carry or move the cleaning device 100. The handle 50 is located at one end close to the center of gravity of the cleaning device 100, so that when the user holds the handle 50, the center of gravity of the cleaning device 100 is closer to the user's point of force application, thereby making the user's grip on the cleaning device 100 more stable and improving the grip feel.

[0044] For example, the handle 50 is located at the top and front end of the device body 10, and the drain hole 15 is located at the rear end of the device body 10 near the bottom. When the user holds the handle 50 to lift the cleaning device 100 out of the water, the drain hole 15 will naturally face downward, causing the second blocking member 40 to rotate under the action of gravity to open the drain hole 15. At the same time, the water in the first cavity 11 will also be discharged from the drain hole 15 under the action of gravity, thereby increasing the drainage speed of the first cavity 11.

[0045] In some embodiments, the cleaning device 100 further includes a buffer 60, which is disposed on the device body 10 and located at one end away from the center of gravity of the cleaning device 100. The buffer 60 is directly opposite to the drain hole 15 and spaced at a preset distance. The buffer 60 is used to buffer the water flowing out of the drain hole 15 when the drain hole 15 is draining, so as to slow down the flow rate of the water discharged from the drain hole 15 and prevent the water discharged from the drain hole 15 from directly impacting the ground or water surface and splashing a large amount of water to the user, thereby improving the user experience.

[0046] For example, the buffer 60 is a baffle located at the rear end of the cleaning device 100. An opening 61 is formed between the baffle and the drain hole 15 towards the bottom of the cleaning device 100. The opening 61 communicates with the outside atmosphere, and water discharged from the drain hole 15 flows out of the cleaning device 100 through the opening 61. In addition, a second shield 40 is located between the baffle and the drain hole 15, so that the baffle can also protect the second shield 40.

[0047] In some embodiments, it is understood that when the cleaning device 100 is removed from the water, the water in the first cavity 11 may also flow into the second cavity 13 through the first vent 12. However, the water flowing into the second cavity 13 is difficult to discharge through the second vent 14 located at the top. Therefore, in order to facilitate the discharge of water from the second cavity 13, a through hole 16 is provided on the bottom cavity wall of the second cavity 13. The through hole 16 communicates with the outside atmosphere. Since the through hole 16 faces the bottom of the cleaning device 100, when the cleaning device 100 is removed from the water, the water flowing into the second cavity 13 can easily flow out of the second cavity 13 through the through hole 16 under the action of gravity, thereby reducing the risk of residual water in the second cavity 13.

[0048] In some embodiments, the cleaning device 100 further includes an electronic control component 70, which is disposed in the first cavity 11 and electrically connected to the water pump assembly 30. The electronic control component 70 and the water pump assembly 30 are disposed near the front end of the cleaning device 100. Since the electronic control component 70 and the water pump assembly 30 account for a large proportion of the total weight of the cleaning device 100, the center of gravity of the cleaning device 100 is closer to the front end.

[0049] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
