A feature described in one embodiment herein may be applied alone or in combination with other features to another embodiment, unless that feature is not applicable in that other embodiment or is otherwise stated.

[0031] The following combination Figures 1-5 This application describes a handheld cleaning device for cleaning pools, comprising a main body 10 with a bottom inlet 1 and an outlet 2. A filter assembly and a power unit 4 are disposed inside the main body 10. The power unit 4 guides water flow into the device from the bottom inlet 1, and after passing through the filter assembly, flows out from the outlet 2.

[0032] like Figure 1 As shown, the cleaning equipment also includes a water replenishment device 5, used to replenish water inside the main body 10 when the water level in the pool is lower than a preset height. The water replenishment device 5 includes a bypass channel 51 and a pumping device 52. The pumping device 52 guides water flow from the bypass channel 51 into the main body 10. The pumping device 52 of the water replenishment device 5 is located at a lower position and connected to the main body 10 through the bypass channel 51, so that when the cleaning equipment is in a shallow water area, the pumping device 52 can pre-draw water to raise the water level inside the main body 10, allowing the power unit 4 to smoothly draw water, and enabling the handheld cleaning equipment to directly draw water from shallow water areas. The power unit 4 drives the water flow into the equipment from the bottom inlet 1, and after being filtered and cleaned by the filter assembly, it flows out from the outlet 2.

[0033] The filter assembly includes a main filter assembly 31 and a secondary filter assembly 32, wherein the secondary filter assembly 32 is disposed between the main filter assembly 31 and the power unit 4.

[0034] Specifically, the main body 10 is provided with a power device fixing frame 6, and the power device 4 is arranged in the power device fixing frame 6 and communicates with the main filter assembly 31. One end of the main filter assembly 31 communicates with the power device 4, and the other end communicates with the bottom water inlet 1. The power device fixing frame 6 is provided with a water guide opening at an end away from the main filter assembly 31, and the water guide opening communicates with the water outlet 2. In a possible implementation, the main filter assembly 31 includes a Hepa filter screen having a sewage filtering function and a dust collection box having a dust collection function.

[0035] The power device 4 includes a driving mechanism 41 and an impeller 42, and the auxiliary filter assembly 32 is arranged below the impeller 42 to filter and protect the impeller 42, so that when the main filter assembly 31 is damaged, impurities such as dirt and large-particle garbage cannot directly enter the impeller 42, thereby avoiding damage to the high-speed rotating impeller 42 and ensuring the stability and reliability of the whole machine.

[0036] Further, the auxiliary filter assembly 32 is provided with a baffle 33 on a side of the auxiliary filter assembly 32 facing the power device 4. The baffle 33 divides the auxiliary filter assembly 32 into a first filter area and a second filter area, and the first filter area is closer to the water outlet of the bypass channel 51 than the second filter area.

[0037] The baffle 33 can block the water flow entering the main body 10 from the bypass channel 51, so that the water flow first contacts and flows through the first filter area, and the water and gas in the main body 10 can be smoothly exchanged when the cleaning device works in a shallow water area. Before the water replenishment work, there is gas in the main body 10. If the water flow entering from the bypass channel 51 directly splashes on the filter screen of the whole auxiliary filter assembly 32, the water and gas in the main body 10 cannot be smoothly exchanged, and the water absorption function of the power device 4 is lost. The baffle 33 avoids the water flow splashing on the whole auxiliary filter assembly 32, thereby ensuring the smooth start of the impeller 42 and the normal work of the device.

[0038] In a possible implementation, the baffle 33 is directly opposite the water outlet of the bypass channel 51 to block the water flow flowing out of the bypass channel 51 from entering the second filter area.

[0039] In a possible implementation, the baffle 33 is of an arc structure to better guide the water flow, reduce the direct impact of the water flow on the baffle 33 and the filter screen 322, and also improve the passing efficiency of the water flow, so that the water flow is more uniformly distributed on the filter screen. In other possible implementations, the baffle 33 can also be designed as a straight line, a broken line, etc.

[0040] Further, the upper edge of the baffle 33 is higher than the bottom of the impeller 42 and lower than the blades 421 of the impeller 42. The arrangement of the baffle 33 avoids direct interference with the impeller 42, and when the impeller 42 rotates at high speed, the baffle 33 can ensure smooth flow of water without additional resistance or noise due to interference. The compact structure reduces the overall space occupied by the secondary filter assembly 32, which helps to reduce the overall volume of the device.

[0041] Further, as shown in Figure 3 The filter screen 322 can be embedded in the filter screen frame 321, and the filter screen frame 322 can be made of hard plastic, metal, or the like. In one possible implementation, the filter screen frame 321 includes a plurality of connecting ribs that are connected to each other to form a mesh structure, and some of the connecting ribs extend toward the side of the filter screen 322 facing the impeller 42 to form the baffle 33. In one possible implementation, the connecting ribs include a plurality of fan-shaped structures and ring-shaped structures that are connected to each other. The arrangement of the connecting ribs improves the structural strength of the filter screen frame 321 and enables the filter screen 322 to be more firmly fixed to the filter screen frame 321.

[0042] Further, the filter screen frame 321 and the baffle 33 are integrally formed. This simplifies the manufacturing process, reduces production costs, and improves the structural strength between the filter screen frame 321 and the baffle 33. The integrated design also ensures close cooperation between the filter screen frame 321 and the baffle 33, avoiding a decrease in filtration efficiency due to looseness or deformation.

[0043] Further, the secondary filter assembly 32 and the main body 10 are detachably connected.

[0044] In one possible implementation, the main body 10 is provided with a power device fixing frame 6, and the secondary filter assembly 32 is detachably connected to the main body 10 through the power device fixing frame 6. In another possible implementation, the outer side of the filter screen frame 321 is provided with a connecting frame 7, and the two ends of the connecting frame 7 are connected to the power device fixing frame 6 and the main body 10, respectively. The edges of the filter screen frame 321 are uniformly provided with a plurality of connecting holes 323, and after the connecting holes 323 are aligned with the corresponding hole positions on the connecting frame 7, fasteners such as screws are passed through the connecting holes 323 and locked to realize the connection between the filter screen frame 321 and the connecting frame 7.

[0045] In a possible implementation, the edge of the filter screen frame 321 is provided with a buckle structure, and the filter screen frame 321 is detachably connected with the connecting frame 7 through the buckle structure. The buckle structure on the edge of the filter screen frame 321 is matched with a corresponding buckle slot on the connecting frame 7. The buckle is pressed slightly to make the buckle elastically deform and be buckled into the buckle slot, and the connection is completed. When disassembled, the buckle is released by pressing the release button on the buckle or slightly prying with a tool, so that the buckle is separated from the buckle slot, and quick disassembly is realized. Without the use of tools, the installation and disassembly can be easily completed, and the user experience is greatly improved.

[0046] The detachable arrangement of the auxiliary filter assembly 32 facilitates quick disassembly and replacement of the auxiliary filter assembly 32, facilitates maintenance and replacement of the impeller 42 in the main body 10 and user cleaning, and reduces maintenance cost and time.

[0047] Further, the connecting frame 7 and the power device fixing frame 6 are provided with a sealing ring 8. The sealing ring 8 can effectively prevent air or liquid from leaking from the connecting gap to ensure the normal operation efficiency of the equipment, increase the stability and tightness of the connecting part to a certain extent, provide additional buffer under the vibration or impact condition after the equipment is started, reduce the relative movement between the connecting parts, and ensure the stable operation of the equipment. Since a reliable seal is formed between the connecting frame 7 and the power device fixing frame 6, the user does not need to worry about additional maintenance work caused by poor sealing when disassembling and replacing the auxiliary filter assembly 32.

[0048] The filter assembly of the present application includes a main filter assembly 31 and an auxiliary filter assembly 32, forming a double filtration mechanism. The auxiliary filter assembly 32 is located between the main filter assembly 31 and the power device 4, effectively preventing impurities such as dirt and large particles of garbage from directly entering the impeller 42, avoiding damage to the high-speed rotating impeller, and ensuring the stability and reliability of the whole machine. The baffle 33 provided on the auxiliary filter assembly 32 optimizes the water flow path during the water replenishing process, blocks the water flow entering from the bypass channel 51 from directly splashing on the entire auxiliary filter assembly 32, and also guides the water flow to flow through the first filter area first, ensuring the smooth start of the impeller 42 and the normal operation of the equipment.

[0049] Obviously, the above-described embodiments are only part of the embodiments of the present specification, rather than all the embodiments. Based on the embodiments in the present specification, those skilled in the art can make other different forms of changes or modifications without creative labor, and all of them should belong to the protection scope of the present specification.
