[0033] The following description is provided in relation to the drawings Figures 1-5 A handheld cleaning device is provided in the embodiments of the present application, which is applied to the cleaning work of a pool and comprises a main body, the main body comprising a bottom water inlet 1, a water outlet 2 and a main flow channel. A power device 3 and a flow guide structure 4 are arranged in the main body. The power device 3 guides the water flow to enter the main flow channel from the bottom water inlet 1 and to flow out from the water outlet 2 after passing through the flow guide structure 4.

[0034] Specifically, a filter assembly and a power device fixing frame 5 are arranged in the main body, the power device 3 is arranged in the power device fixing frame 5 and communicates with the filter assembly. One end of the filter assembly communicates with the power device 3 and the other end communicates with the bottom water inlet 1. The main flow channel comprises an internal passage formed by the bottom water inlet 1, the filter assembly, the power device fixing frame 5 and the power device 3. The end of the power device fixing frame 5 away from the filter assembly is provided with the flow guide structure 4, and a flow guide opening 41 of the flow guide structure 4 communicates with the water outlet 2.

[0035] The flow guide structure 4 is arranged in the main body in the present application, so that when the cleaning device is working, the water flow passes through the main flow channel and the flow guide structure 4 before flowing out from the water outlet 2, which effectively avoids the problem that the external air enters the internal passage of the main flow channel when the water quantity in the main flow channel is reduced or the device is in an inclined state, thereby preventing the occurrence of the idling phenomenon of the impeller of the power device 3, so that the handheld cleaning device can also maintain strong dirt suction capacity in the shallow water area, and the working efficiency and cleaning effect are improved.

[0036] Further, the power device 3 comprises an impeller 31, and the flow guide structure 4 is arranged between the impeller 31 and the water outlet 2 along the direction of the main flow channel. The flow guide structure 4 comprises a flow guide opening 41 corresponding to the water outlet 2.

[0037] Specifically, the power device 3 comprises a driving member 30 and an impeller 31, which are drivingly connected. The guide structure 4 is arranged between the impeller 31 and the water outlet 2 along the main flow path direction, guiding the water flow from the main flow path to the water outlet 2 through the guide opening 41.

[0038] Further, the guide structure 4 is provided with a baffle 42, which is used to block the water flow from directly flowing out of the guide opening 41. The arrangement of the baffle 42 increases the drainage height of the water flow when it leaves the main flow path, optimizes the water flow path, and reduces the area of the guide opening 41 actually participating in the guide. When the water flow intensity in the main flow path weakens, the presence of the baffle 42 ensures the continuous filling of the guide opening 41, forms an effective barrier, and blocks the external air from entering the main flow path, thereby reducing the problems such as noise, efficiency reduction, and equipment damage that may be caused by the mixing of air.

[0039] Further, the baffle 42 is integrally formed with the guide structure 4, which improves the overall firmness and durability, reduces the risk of water leakage caused by loose connection or wear between components, and simplifies the installation and maintenance process. Compared with the baffle that needs to be installed and fixed separately, the integrally formed guide structure 4 is more convenient to install. In some possible embodiments, the baffle can be designed in different shapes, such as arc-shaped, wavy-shaped, etc.

[0040] Further, the highest point of the upper edge of the baffle 42 is substantially at the same height as the lowest point of the upper edge of the guide opening 41. The height design of the upper edge of the baffle 42 and the upper edge of the guide opening 41 helps to prevent external air from entering the inside of the main flow path when the water flow intensity in the main flow path weakens or the equipment is in a tilted state. When the water flow intensity in the main flow path weakens, the presence of the baffle 42 forms an effective barrier, blocking the external air from entering the main flow path through the guide opening 41. Since the upper edge of the baffle 42 is at about the same height as the upper edge of the guide opening 41, it is more difficult for air to bypass the baffle 42 and enter the main flow path, thereby effectively avoiding the occurrence of the idle running of the impeller of the power device 3.

[0041] Further, the lower edge of the guide opening 41 is configured as an inclined guide surface 411, which can more effectively guide the water flow. When the water flow passes through the guide structure 4 from the main flow path, the inclined guide surface 411 can provide a smooth transition, making the water flow more smoothly through the guide opening 41 to the water outlet 2, reducing the resistance and disorder of the water flow at the guide opening 41, and improving the efficiency and stability of the water flow.

[0042] Further, the side of the flow guide surface 411 away from the impeller 31 is lower than the side of the flow guide surface 411 closer to the impeller 31. When the water flow exits the impeller 31 and passes through the flow guide structure 4, due to the inclined design of the flow guide surface 411, the water flow will gain more propulsion on the side away from the impeller 31. This propulsion enables the water flow to move more rapidly towards the water outlet 2, reducing the residence time and energy loss of the water flow, and improving the water outlet efficiency and cleaning ability of the device.

[0043] Further, the side of the flow guide surface 411 closer to the power device 3 abuts against the baffle 42. The close fit between the flow guide surface 411 and the baffle 42 ensures that the water flow can be more precisely controlled and guided when passing through the flow guide structure 4, helping to reduce the turbulence and energy loss of the water flow, and improving the efficiency and stability of the water flow. In the case of device tilting or water flow weakening, the presence of the baffle 42 ensures the continuous filling of the flow guide opening 41, while the inclined design of the flow guide surface 411 further enhances the drainage capacity, enabling the water flow to flow more smoothly out of the water outlet 2.

[0044] In one possible implementation, the side of the flow guide surface 411 closer to the power device 3 is connected to or integrally formed with the baffle 42.

[0045] Further, the lowest point of the side of the flow guide surface 411 away from the power device 3 is substantially at the same height as the impeller 31. When the lowest point of the flow guide surface 411 is at the same height as the impeller 31, there is no impact on the flow, but rather the water flow exiting the impeller 31 can transition more smoothly onto the flow guide surface 411, forming a continuous, high-speed water flow channel along the inclined flow guide surface, helping to enhance the siphon effect, so that the water flow can maintain a high speed and pressure after leaving the impeller 31, accelerating the water flow through the flow guide structure 4 and towards the water outlet 2, improving the water outlet efficiency of the device and enhancing the cleaning ability and working efficiency of the cleaning device.

[0046] Further, the flow guide structure 4 comprises a first half-shell 401 and a second half-shell 402 that are detachably connected. Specifically, as shown in Figure 4 and 5 , the first half-shell 401 and the second half-shell 402 are connected to and

[0047] fixed to the power device fixed frame 5, and

[0048] are arranged above the power device fixed frame 5. The first half-shell 401 and the second half-shell 402 can be detachably connected by screws, nuts or buckles, etc. The detachable first half-shell 401 and the second half-shell 402 enable the flow guide structure 4 to be easily disassembled when maintenance or cleaning is required, simply by disassembling the two half-shells.

[0049] The flow guide opening 41 is arranged on the second half shell 402, and / or the baffle plate 42 is arranged on the second half shell 402. In one possible implementation, the flow guide opening 41 and the baffle plate 42 are integrally formed with the second half shell 402, and the baffle plate 42 is arranged inside the second half shell 402, close to the flow guide opening 41, for adjusting and guiding the direction and speed of the water flow entering the flow guide opening 41. In another possible implementation, the flow guide opening 41 is integrally formed with the second half shell 402, and the baffle plate 42 can be fixed on the second half shell 402 as an independent component by means of fasteners, adhesives, or the like, and is located inside the flow guide opening 41.

[0050] Further, the side walls of the second half shell 402 on both sides of the flow guide opening 41 extend forward of the flow guide opening 41 to form flow guide side plates. The flow guide side plates are used to guide the water flow to pass through the flow guide opening 41 more smoothly, reducing the turbulence and energy loss of the water flow. When passing through the flow guide side plates, the water flow is effectively guided in the direction of the water outlet 2, thereby improving the efficiency and stability of the water flow.

[0051] Further, the inner side of the flow guide structure 4 is provided with a connecting groove, and the flow guide structure 4 is connected with the power device fixing frame 5 through the connecting groove. In one possible implementation, the inner wall of the second half shell 402 is provided with a connecting groove, and the second half shell 402 is matched and clamped with the upper edge of the power device fixing frame 5 through the connecting groove.

[0052] Further, when the handheld cleaning device is in the upright state, the height difference between the upper edge of the baffle plate 42 and the impeller 31 is H, and when the handheld cleaning device is in the inclined state, the height difference between the upper edge of the baffle plate 42 and the impeller 31 is h, wherein H>h, as shown in Figure 3 By setting reasonable height differences H and h, the water flow requirements in different use states can be adapted to, and no matter in the upright state or the inclined state, the baffle plate 42 can effectively block the air from entering the flow channel inside, avoid the phenomenon of impeller idling caused by air mixing, and also do not affect the stable dirt suction performance of the whole machine at the inclined angle, so that the device can maintain a high-efficiency working state, and the adaptability and flexibility of the device are enhanced.

[0053] In one possible implementation, the baffle plate 42 can be arranged as an adjustable baffle plate, and the baffle plate 42 can be connected with the flow guide structure 4 through a sliding rail, a rotating shaft, or an elastic connecting piece, or the like. In different use states, by adjusting the height of the baffle plate 42, the water flow can be adjusted to flow out of the water outlet 2 at the best angle and speed. No matter in the upright state or the inclined state, the handheld cleaning device of the present application can adjust the height difference between the baffle plate 42 and the impeller and the blocking effect of the baffle plate, to ensure the effective guidance of the water flow and the effective isolation of the air, so that the device can maintain a high-efficiency working state in various complex environments.

[0054] Further, H has a value range of 40-80 mm. In some possible implementation manners, H can be 40 mm, 45 mm, 50 mm, 55 mm, 60 mm, 65 mm, 70 mm or 80 mm.

[0055] The handheld cleaning device provided in the application is provided with a flow guide structure, which can effectively guide the water flow to flow out of the water outlet from the flow guide structure after passing through the main flow channel, thereby avoiding the problem that external air enters the main flow channel to affect the idling of the impeller in the state of reduced water flow in the main flow channel or device inclination, optimizing the water flow path, reducing the turbulence and energy loss of the water flow, and improving the outflow efficiency and stability of the water flow.

[0056] Through test verification, the handheld cleaning device provided in the application can meet the ability of continuously sucking dirt in a shallow water area when being shaken violently or being inclined at any angle.
