[0002] The water filtration system is an essential component of pool cleaning and maintenance equipment, and its performance is directly related to the cleanliness of the pool water and the efficiency of the equipment. Water filtration systems are typically equipped with a filter assembly. However, in actual use, pool water often contains impurities such as particles of varying sizes, algae, and hair. These impurities are drawn into and flow through the filter, where they gradually accumulate and adhere to the filter. This reduces the filter aperture, reduces filtration efficiency, and can even lead to complete clogging, affecting the normal operation of the equipment and forcing users to frequently shut down the system for inspection and cleaning. Once the filter is clogged, it not only loses its ability to effectively filter impurities, but can also damage the pump or motor due to the obstructed water flow, increasing repair costs.

[0003] Many existing pool vacuum cleaners have a fixed connection between the dust collection box and the main unit. This means users have to disassemble the entire unit to clean or replace the filter, a cumbersome and time-consuming process. This not only increases maintenance costs but can also damage the unit due to improper handling during disassembly. Utility Model Content

[0033] The following combination Figures 1-6 A handheld swimming pool vacuum cleaner provided in an embodiment of the present application is introduced, comprising a body 1 and a dust collection box 2 detachably connected to the body 1 .

[0034] The machine body 1 includes a water pump, at least one water outlet 12 and at least one water suction port 11 . The water pump is used to transfer water from the water suction port 11 to the dust box 2 and to the water outlet 12 .

[0035] The dust box 2 includes a water inlet 20 and a filter 21 that can be at least partially placed inside the dust box 2. The water inlet 20 is arranged at the bottom of the dust box 2 and can be connected to the water suction port 11 after the dust box 2 is connected to the body.

[0036] The dust box 2 of this handheld pool vacuum cleaner is detachably connected to the body 1, allowing the filter 21 to be at least partially placed inside the dust box 2. This makes it easier and quicker for users to replace or clean the filter 21 and dust box 2 during use. This allows maintenance of key components without disassembling the entire device, significantly reducing maintenance costs and time. The handheld design makes the vacuum cleaner extremely flexible to operate, allowing users to easily clean any corner of the pool without being restricted by fixed equipment or long electrical cords.

[0037] Furthermore, the dust box 2 includes a handle 23 and a snap-fitting portion. The handle 23 is located on the side of the dust box 2, and the snap-fitting portion is located on the side away from the handle 23. The handle 23 is convenient for the user to grasp and thereby assemble and disassemble the dust box 2. The handle 23 can be configured as a raised or recessed structure provided on the side of the dust box 2. In one possible embodiment, the handle 23 is integrally formed with the dust box 2. In other possible embodiments, the handle 23 can be fixed to the dust box 2 by screws or snaps to ensure a secure connection. The snap-fitting portion is configured to cooperate with a corresponding structure on the body 1 to achieve a detachable connection between the dust box 2 and the body 1. The snap-fitting portion can be configured as a raised snap, a slot, a rotating lock, or the like, which cooperates with a corresponding groove, protrusion, or rotating shaft on the body 1. The design of the handle 23 and the snap-fitting portion in this embodiment allows the user to easily and quickly assemble and disassemble the dust box 2, thereby facilitating the cleaning or replacement of the filter 21 and the interior of the dust box 2, reducing maintenance costs and time.

[0038] Furthermore, the dust box 2 also includes a check structure 22, which is arranged on the inner wall of the dust box 2 or on the outer wall of the filter element 21. When the filter element 21 is at least partially installed in the dust box 2, the check structure 22 is located in the lower area of the filter element 21 and separates the space below at least a part of the filter element 21 to prevent the sediment at the bottom of the dust box 2 from rising with the water flow to the area where at least a part of the filter element 21 is located.

[0039] Specifically, the body 1 is provided with a water pump that draws water from the water inlet 11 of the body 1, filters it through the dust box 2, and then discharges it from the drain outlet 12. The dust box 2 can be detachably connected to the body 1 through structures including, but not limited to, snap-fit and threaded connections. In one possible embodiment, the dust box 2 can be configured for front detachment. The body 1 is provided with at least one mounting structure, and corresponding mounting and mating structures are provided at corresponding positions on the edge of the dust box 2. During installation, the dust box 2 is aligned with the mounting position on the body 1 and pushed forward until the mounting structure and the mating structure engage, achieving a secure connection. During removal, the dust box 2 can be pulled outward by pressing a button provided on the dust box 2 or the body 1, or by directly pulling the dust box 2 outward. The mounting structure and mating structures include, but are not limited to, a snap-fit groove and a snap-fit protrusion, a hook groove and a hook, and other connecting structures. When the dust box 2 is installed on the body 1, the water inlet 20 at the bottom of the dust box 2 communicates with the water inlet 11 of the body 1. A check structure 22 and a filter element 21 are provided within the dust box 2. The check structure 22 is disposed on the inner wall of the dust box 2 or the outer wall of the filter element 21. When the filter element 21 is properly installed within the dust box 2, the check structure 22 separates at least a portion of the space below the filter element 21 from the bottom of the dust box 2, effectively preventing sediment at the bottom of the dust box 2 from rising with the water flow to the filter element 21. In some possible embodiments, the filter element 21 may be partially or completely disposed within the dust box 2 to facilitate disassembly, cleaning, and other operations.

[0040] The handheld swimming pool vacuum cleaner of this embodiment can effectively prevent the sediment at the bottom of the dust box 2 from rising to the area where the filter element 21 is located with the water flow by providing a non-return structure 22 in the dust box 2, thereby reducing the risk of clogging of the filter element 21; the reasonable layout of the non-return structure 22 and the filter element 21 ensures that the water flow can more effectively capture and intercept impurities when passing through the filter element 21, preventing the deposited dirt from being re-driven by the water flow, and protecting the filter element 21 from impact and wear, thereby extending the service life of the filter element 21; the dust box 2 is detachably connected to the body 1, which is convenient for users to easily remove and clean the filter element, reducing the difficulty of maintenance and improving the convenience of cleaning work.

[0041] Furthermore, a check structure 22 is provided on the inner wall of the dust box 2, and the check structure 22 includes a baffle, a filter screen, or a raised structure. In one possible embodiment, the check structure 22 includes at least one baffle, which is integrally formed with the inner wall of the dust box 2 or supported by a support structure and arranged in the dust box 2. In other possible embodiments, the check structure 22 is provided as a filter screen structure, which is directly laid at a certain height above the bottom of the dust box 2. The filter screen can not only intercept some impurities that rise with the water flow, but also allow most of the clean water flow to pass through, reducing the direct pressure on the filter element 21; the check structure 22 can also be provided as an annular or spiral raised structure on the inner wall of the dust box 2, which prevents sediment from rising directly with the water flow to the area where the filter element 21 is located through the raised structure. Preferably, the raised structure is provided with tiny pores to perform preliminary filtration of the water flow.

[0042] Furthermore, a check structure 22 is provided at the bottom of the filter element 21 and comprises a flexible material. In one possible embodiment, the check structure 22 is configured as a skirt structure connected to at least a portion of the bottom of the filter element 21. The skirt structure can be installed by methods including, but not limited to, embedding into the bottom housing of the filter element 21, bonding to the housing of the filter element 21, and snap-fit connection. Preferably, the skirt structure can be made of, but not limited to, silicone, rubber, or other flexible materials with good elasticity and water resistance. Preferably, the side of the check structure 22 connected to the filter element 21 is provided with an opening for water flow, and the other side is in contact with the inner wall of the dust box 2. Placing the check structure 22 at the bottom of the filter element 21 can prevent dirt and sediment from rising, extending the life of the filter element and improving cleaning efficiency. The flexible material also acts as a buffer, reducing the direct impact of water and dirt on the filter element, while also facilitating the disassembly and cleaning of the dust box 2 and filter element 21.

[0043] Furthermore, the check structure 22 is provided near the water inlet 20 .

[0044] Specifically, the check structure 22 is arranged near the periphery of the water inlet 20, which is conducive to the water flow entering from the water inlet 20 being guided and restricted by the check structure 22 at the first time, effectively preventing the dirt in the water from rising directly with the impact of the water flow and contacting the filter element 21.

[0045] Furthermore, the side of the non-return structure 22 away from the inner wall of the dust collecting box 2 extends obliquely toward the bottom of the dust collecting box 2 .

[0046] Specifically, in order to further enhance the non-return effect, the side of the non-return structure 22 away from the inner wall of the dust box 2 is designed to extend obliquely toward the bottom of the dust box 2, which is beneficial to increase the contact area between the non-return structure 22 and the water flow. The principle of gravity is also used to make the water flow more smoothly to the bottom of the dust box 2 when passing through the non-return structure 22. At the same time, the sediment is effectively blocked under the non-return structure 22, reducing the risk of blockage of the filter element 21 and improving the cleaning efficiency.

[0047] In this embodiment, the check structure 22 is arranged close to the water inlet 20 and is designed to extend obliquely toward the bottom of the dust collecting box 2, thereby effectively preventing the risk of sediment rising with the water flow and entering the filter element 21 area, and significantly reducing the possibility of filter element clogging.

[0048] Furthermore, the filter element 21 includes a pleated filter screen. Specifically, the filter element 21 utilizes a pleated filter screen design, which increases the surface area of the filter screen and improves filtration efficiency and capacity. The pleated filter screen can more effectively capture and intercept impurities and particulate matter in the water flow, ensuring clearer water quality after cleaning. At the same time, the pleated structure also has a certain degree of elasticity and toughness, which can withstand a certain degree of water flow impact and mechanical vibration, thereby extending the service life of the filter element 21. In one possible embodiment, the pleated filter screen is a HEPA filter screen.

[0049] Furthermore, a check valve 4 is provided at the water inlet 20. This check valve 4 automatically prevents water from flowing in the opposite direction out of the water inlet 20. When water enters the dust box 2 from the water inlet 20, the check valve 4 automatically opens to allow water to flow through. However, when the water attempts to flow in the opposite direction, the check valve 4 closes to prevent backflow. This effectively prevents the water and dirt that have entered the dust box 2 from flowing back out, ensuring a stable and continuous cleaning process.

[0050] Furthermore, it includes a sewage suction head 3, which is rotatably connected to the body 1. In one possible embodiment, the sewage suction head 3 is connected to the body 1 through a universal joint 5 to achieve flexible sewage suction in all directions. In other possible embodiments, the sewage suction head 3 can also be connected to the body 1 through a ball hinge, a multi-joint arm, etc. The sewage suction head 3 is rotatably connected to the body 1, so that the sewage suction head can rotate within a certain angle, thereby improving the flexibility of the sewage suction head in the sewage suction direction, improving the cleaning efficiency and effect, and enabling it to adapt to more complex terrains and cleaning needs. At the same time, it can improve the hand feel comfort during operation and reduce the operator's fatigue.

[0051] Furthermore, a sewage suction port 31 is provided at the bottom of the sewage suction head 3, and the sewage suction port 31 is configured to allow water to flow into the sewage suction head 3 in a direction parallel to the horizontal plane, and the sewage suction port 31 is connected to the water suction port 11. In some possible embodiments, the opening shape of the sewage suction port 31 includes but is not limited to a rectangle and a circle, and the opening edge of the sewage suction port is configured to be a straight line or an arc segment parallel to the horizontal plane. The design of the sewage suction port 31 helps to maximize the use of the power of the water flow, so that the water flow can enter the sewage suction machine smoothly and efficiently, while reducing the resistance and turbulence caused by improper water flow direction. In this embodiment, the sewage suction port 31 is connected to the water suction port 11 on the body 1 through a sealed and efficient pipe, so that the water flow can be smoothly sucked in from the bottom of the pool and transported to the body 1 for subsequent filtration treatment.

[0052] Furthermore, a guide groove 32 is provided at the bottom of the sewage suction head 3, located in the water inlet direction of the sewage suction port 31. The guide groove 32 is used to guide the water flow into the sewage suction port in a more concentrated and orderly manner, optimizing the path of water entering the sewage suction port 31 and improving sewage suction efficiency. Preferably, the guide groove 32 has a V-shaped opening structure and gradually narrows toward the sewage suction port 31. The gradual narrowing of the opening of the guide groove 32 toward the sewage suction port 31 can further accelerate the water flow and enhance the sewage suction effect.

[0053] Furthermore, a counterweight 33 is provided in the sewage suction head 3. The counterweight 33 can be fixedly installed in the sewage suction head 3 by providing a mounting groove or a fixing frame or other structures inside the shell. The shape of the counterweight 33 matches the installation space. Optionally, the counterweight 33 can be designed into a regular geometric shape such as a cube, a rectangular parallelepiped or a cylinder to facilitate processing and installation. The provision of the counterweight 33 can increase the weight of the sewage suction head 3, so that the sewage suction port 31 can always be close to the ground, prevent the phenomenon of floating in water, and improve the sewage suction effect. At the same time, the counterweight 33 balances the center of gravity of the sewage suction head 3, reduces the shaking and vibration caused by the offset of the center of gravity during use, and improves the stability and safety of the equipment.

[0054] The suction head 3 of this embodiment optimizes the water suction path and enhances the suction effect through the design of the bottom suction port 31 combined with the guide groove 32. At the same time, the built-in counterweight block 33 enables the suction head 3 to remain close to the ground for suctioning sewage, further improving the suction effect and enhancing the stability, safety and operating comfort of the equipment.

[0055] This embodiment of the handheld pool vacuum cleaner uses a built-in pump in the body 1 to generate suction, driving pool water into the vacuum port 31 and flowing through the dust box 2. A check structure 22 within the dust box 2 effectively traps sediment beneath the filter element 21, which then filters the drawn-in pool water. The filtered, clean water is ultimately discharged through the drain port 12, purifying and circulating the pool water. Throughout this process, the detachable design of the dust box 2 and body 1 facilitates cleaning and maintenance, ensuring the vacuum cleaner's continued efficient operation.
