[0002] A vacuum cleaner is a widely used cleaning device for water bodies such as swimming pools and fishponds. Its main function is to keep the water clean by removing dirt and sediment. However, in actual use, the floor brush of the vacuum cleaner often faces some technical challenges in cleaning the junction of the pool wall and the pool bottom.

[0003] The bottom of the pool wall has a complex structure, often with a certain slope and curved surface, forming an angle with the pool bottom. This irregular terrain makes it difficult for the floor brush to fully adhere to the bottom of the pool wall during cleaning, resulting in some dirt and sediment not being effectively removed. In addition, the dirt on the bottom of the pool wall is often quite stubborn, especially if it has not been cleaned for a long time, and the dirt may adhere to the pool wall, increasing the difficulty of cleaning. Utility Model Content

[0019] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0020] Example 1 like Figure 1-4 As shown, a floor brush 1 includes a rigid body 11 and multiple flexible attachments 12. The flexible attachments 12 are distributed at both ends of the rigid body 11 and connected to the rigid body 11. Both the bottom of the rigid body 11 and the bottom of the flexible attachments 12 are provided with bristles 14 for cleaning. The rigid body 11 is made of a rigid material, such as polyethylene (PE) or polypropylene (PP), which ensures that it is not easily deformed under high-pressure suction or force, maintaining the rigidity of the overall structure and extending its service life. The flexible attachments 12 are made of easily deformable soft materials, such as rubber or silicone, which can deform under external force. For example, as... Figure 4As shown, during the cleaning process of the pool, the rigid body 11 and flexible attachment 12 of the floor brush 1 are in close contact with the pool bottom 300 or pool wall 200. When cleaning the junction of the pool wall 200 and the pool bottom 300, the rigid body 11 can maintain contact with the pool bottom 300, and the flexible attachment 12 can deform under force to fit into the junction between the pool wall 200 and the pool bottom 300, thereby completing the cleaning of the junction between the pool wall 200 and the pool bottom 300 and reducing cleaning dead corners.

[0021] It is understood that in other embodiments, the flexible attachment 12 can be provided only at one end of the rigid body 11. When it is necessary to clean the intersection of the pool wall 200 and the pool bottom 300, the deformability of the flexible attachment 12 can be used to fit against the bottom of the pool wall 200, and the cleaning of that position can also be achieved.

[0022] Example 2 like Figure 5-8 As shown, a vacuum cleaner 100 includes a floor brush 1, a dirt collection component 2, and a main unit 3. The dirt collection component 2 is connected between the floor brush 1 and the main unit 3. The floor brush 1 is the type described in Embodiment 1.

[0023] Continue to refer to Figure 1-3 As shown, the structure of the floor brush will be further described. Specifically, a suction head 13 is connected to the rigid body 11 of the floor brush 1. The rigid body 11 has a mounting port 111 for mounting the suction head 13. The suction head 13 has an open structure at both ends, forming a suction channel 131 inside. A suction chamber 15 is formed on the side of the rigid body 11 facing away from the suction head 13. The first end of the suction channel 131 communicates with the suction chamber 15, and the second end of the suction channel 131 communicates with the dirt collection assembly 2. Furthermore, the suction head 13 is rotatably connected to the mounting port 111 so that after connecting the dirt collection assembly 2, the dirt collection assembly 2 and the main unit 3 can rotate relative to the floor brush 1, making it convenient for the user to operate while standing by the pool, allowing for more flexible cleaning of the pool.

[0024] Furthermore, to allow users to more clearly see the cleaning status of the dirt when operating the vacuum cleaner 100, a transparent observation section 16 is provided on one side of the rigid body 11. Additionally, as... Figure 3 As shown, the observation section 16 is also provided with a suction port 161 to facilitate the entry of dirt into the suction chamber 15. It can be seen that in this embodiment, the suction port 161 is formed by opening a notch at the bottom of the observation section 16, so that dirt can enter the suction chamber 15 from the suction port 161, and at the same time, it is convenient for the user to observe the cleanliness of the dirt in the pool from the water surface.

[0025] The waste collection assembly 2 includes a first housing 21, the first end of which is connected to the suction head 13. A connecting cavity 25 and a waste collection cavity 24 are formed within the first housing 21, communicating with each other. The connecting cavity 25 is used to connect with the suction head 13. When the vacuum cleaner 100 is working, waste from the bottom of the pool can enter the suction head 13, and then enter the waste collection cavity 24 through the suction channel 131 and the connecting cavity 25.

[0026] The vacuum cleaner 100 also includes a filter element 4, which is located in the dirt collection chamber 24 and connected to the first end of the main unit 3. Preferably, the filter element 4 has a conical structure and covers the first end of the main unit 3 so that dirt can be intercepted in the dirt collection chamber 24, preventing dirt from entering the main unit 3 and affecting the operation of the vacuum cleaner 100. The tip of the filter element 4 faces the connecting cavity 25.

[0027] Furthermore, a one-way valve 22 is provided at the connection point between the connecting cavity 25 and the collection cavity 24. The one-way valve 22 is installed on the connecting cavity 25 and allows liquid to enter the collection cavity 24 from the connecting cavity 25 in one direction, thereby preventing the dirt intercepted in the collection cavity 24 from flowing back into the pool through the suction channel 131.

[0028] The main unit 3 provides power to the vacuum cleaner 100. The main unit 3 includes a second housing 31 and a turbine 32, a motor 33, and a battery 34 disposed within the second housing 31. The output shaft of the motor 33 is connected to the turbine 32, which is positioned between the filter element 4 and the motor 33. The battery 34 is electrically connected to the motor 33. In this embodiment, the second housing 31 and the first housing 21 can be fastened together with snap-fit ​​mechanisms for quick connection and disassembly.

[0029] To discharge the pool water sucked up during the suction process, a drain outlet 311 is provided on the second housing 31. Multiple drain outlets 311 are provided and distributed around the turbine 32. In this embodiment, the drain outlets 311 are multiple elongated holes, and are distributed symmetrically on both sides of the second housing 31. In other embodiments, the drain outlets 311 can also be multiple round holes, elliptical holes, or oblong holes. When the vacuum cleaner 100 is working, the motor 33 drives the turbine 32 to rotate, generating suction. Pool water carrying debris enters the suction head 13 through the suction port 161, then through the suction chamber 15, and finally through the one-way valve 22 into the collection chamber 24. After being filtered by the filter element 4, the pool water is discharged from the drain outlet 311, while the debris and other waste remain in the collection chamber 24.

[0030] After the user finishes using the vacuum cleaner 100 and turns off the power, the one-way valve 22 closes. After removing the vacuum cleaner 100 from the pool, a large amount of pool water and debris remains in the collection chamber 24. At this point, emptying the debris and water by unfastening the first housing 21 and the second housing 31 would be inconvenient. Therefore, a drain port 26 and a drain cover 23 that can be fastened to the drain port 26 are provided at the first end of the first housing 21. The drain cover 23 is rotatably connected to the first housing 21 so that it remains connected to the first housing 21 even after the drain port 26 is opened, preventing loss. When the vacuum cleaner 100 is working, the brush head 1 faces downwards. Therefore, when it is necessary to empty the debris and pool water in the collection chamber 24, the drain port 26 can be opened by flipping the drain cover 23, allowing the wastewater to flow out directly, thus achieving a rapid drainage effect.

[0031] In addition, the vacuum cleaner 100 also includes a handle 5, which is mounted on the second housing 31 of the main unit 3. Furthermore, the handle 5 can be configured as a telescopic structure to facilitate user operation and cleaning.
