Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaning equipment technology. Background Technology

[0002] Vacuum cleaners, as a common household cleaning appliance, are widely used in daily cleaning of homes and various offices and commercial spaces. With the increasing number of pet owners, vacuum cleaners specifically designed for cleaning pet hair have emerged. These vacuum cleaners for removing pet hair typically require powerful suction and special brush heads or filtration systems to effectively remove and hold fine, easily tangled pet hair.

[0003] In known vacuum cleaner designs, particularly portable, handheld, or partially upright models, a removable dust collection container (often called a "dust cup") is commonly used to collect dust and debris. Users need to periodically remove the dust cup to clean the accumulated hair and dust, maintaining the vacuum cleaner's filtration efficiency and unobstructed flow. However, existing vacuum cleaners of this type have a significant design and safety flaw. When the user removes the dust cup from the main unit to clean it, the interface on the main unit that connects to the dust cup—the vent leading to the suction motor—is directly exposed. This greatly reduces the product's safety and reliability, especially in everyday use scenarios involving liquid cleaning or humid environments, posing potential dangers and inconvenience to users. Utility Model Content

[0004] In order to solve the problems mentioned above, the purpose of this utility model is to provide a vacuum cleaner that can effectively prevent liquid from entering the suction motor through the exposed vent.

[0005] Therefore, this application provides a vacuum cleaner, comprising: a base, which can be supported on a plane and has a receiving chamber thereon, the base including a bottom wall defining the bottom of the receiving chamber, the bottom wall having a first fluid docking portion having a plurality of vent holes; a suction motor, disposed within the base, the plurality of vent holes being in flow communication with the suction motor; a waterproof cover, installed at the first fluid docking portion and positioned above the plurality of vent holes to cover them, so that liquid falling from above the waterproof cover will not directly fall into the plurality of vent holes; and a dust cup, having a gas-solid separation chamber inside and being detachably installed in the receiving chamber, the dust cup having a bottom opposite the bottom wall, the bottom of the dust cup having a second fluid docking portion having a plurality of vent holes in flow communication with the gas-solid separation chamber; when the dust cup is installed in the receiving chamber, the waterproof cover is located between the plurality of vent holes and the plurality of vent holes, and the plurality of vent holes and the plurality of vent holes maintain airflow communication.

[0006] In some embodiments, in the first fluid docking portion and the second fluid docking portion, one docking portion is a concave structure and the other docking portion is a convex structure.

[0007] In some embodiments, the first fluid docking portion protrudes upward relative to the bottom wall.

[0008] In some embodiments, the first fluid docking portion is hub-shaped, and a positioning hole is provided in the middle of the first fluid docking portion. The waterproof cover has a dome-shaped cover body and a positioning post located in the center of the cover body; the positioning post is inserted into the positioning hole.

[0009] In some embodiments, the waterproof cover further has a plurality of support ribs located inside the cover body; the lower ends of the plurality of support ribs abut against the bottom wall and form a gap between the upper edge of the first fluid docking portion and the cover body, such that the plurality of vent holes and the plurality of air outlet holes maintain airflow communication.

[0010] In some embodiments, the second fluid docking portion is a concave structure and has a mesh wall defining the plurality of air outlets.

[0011] In some embodiments, the second fluid docking portion is provided with a filter HEPA filter; in terms of the airflow direction leaving the gas-solid separation chamber, the filter HEPA filter is located downstream of the plurality of air outlets.

[0012] In some embodiments, the waterproof cover is configured to be non-removably mounted on the first fluid interface.

[0013] In some embodiments, the base includes a sidewall defining the side edge of the receiving chamber, an air inlet on the sidewall, and the dust cup has a cup sidewall with a dust-laden airflow inlet adapted to the air inlet; when the dust cup is installed in the receiving chamber, the air inlet and the dust-laden airflow inlet are fluidly connected.

[0026] like Figures 1 to 2 As shown, this embodiment provides a vacuum cleaner 100, which generally includes a base 1, a suction motor 2, a waterproof cover 3, and a dust cup 4.

[0027] The base 1 can be supported on a flat surface, such as the ground or a tabletop. The interior of the base 1 has a receiving chamber 11 for accommodating the dust cup 4. The receiving chamber 11 is defined by a bottom wall 12 and a side wall 13 extending upward from the edge of the bottom wall 12. A first fluid-connecting portion 14 protruding upward is provided on the bottom wall 12. An air inlet 133 is provided on the side wall 13. This air inlet 133 can be fluidly connected to the suction hose of the vacuum cleaner 100 to introduce dust-laden airflow into the connected dust cup 4.

[0028] like Figure 3 As shown, the base 1 consists of an inner shell 101 and an outer shell 102 arranged inside and outside, forming a cavity between the inner shell 101 and the outer shell 102. The suction motor 2 is arranged between the shells 101 and 102. The bottom wall 12, side wall 13, receiving cavity 11, and first fluid docking part 14 are all defined by the inner shell 1301.

[0029] The suction motor 2 is arranged in the cavity between the inner shell 101 and the outer shell 102, and is located below the receiving chamber 11. The air inlet 21 of the suction motor 2 is in fluid communication with a plurality of vent holes 142 of the first fluid docking part 14, so that clean air filtered by the dust cup 4 can be drawn in by the suction motor 2 and finally discharged.

[0030] like Figure 4 As shown, the first fluid docking part 14 is hub-shaped, with a positioning hole 141 in its middle. The first fluid docking part 14 has a plurality of vent holes 142.

[0031] like Figure 2 , Figure 5 , Figure 6 and Figure 7As shown, the waterproof cover 3 is positioned above the first fluid connection portion 14. The waterproof cover 3 has a dome-shaped cover body 31. A positioning post 32 extends downward from the inner center of the cover body 31. During installation, the waterproof cover 3 can be quickly positioned and fixed by inserting the positioning post 32 into the positioning hole 141 in the middle of the first fluid connection portion 14. The outer peripheral edge 311 of the cover body 31 is located outside the first fluid connection portion 14, so that liquid flowing down from the upper side of the waterproof cover 3 will be guided to the outside of the first fluid connection portion 14, thus preventing the liquid from directly flowing into the multiple vent holes 142.

[0032] To ensure airflow passage, multiple support ribs 33 are provided on the inner side of the cover 31. When the waterproof cover 3 is installed in place, the lower ends of these support ribs 33 abut against the bottom wall 12 of the receiving chamber 11, thereby maintaining a certain gap 34 between the cover 31 and the upper edge of the first fluid docking portion 14. This gap 34 allows airflow flowing from the upper side of the waterproof cover 3 to flow through the gap 34 to the multiple vent holes 142. In some embodiments, the waterproof cover 3 is configured to be non-removably installed on the first fluid docking portion 14 to ensure the stability of its waterproof effect.

[0033] like Figure 2 , Figure 5 and Figure 6 As shown, the dust cup 4 is a cylindrical component with a bottom 42, side walls 46, and top wall 45. The interior of the dust cup 4 has a gas-solid separation chamber 41 for gas-solid separation. In this example, the dust cup 4 can be inserted into and installed in the receiving compartment 11 of the base 1 from top to bottom. The bottom 42 of the cup is opposite to the bottom wall 12 of the base 1. The side wall 46 is provided with a dust-laden airflow inlet 461 adapted to the air inlet interface 133.

[0034] At the center of the cup bottom 42, there is an upwardly recessed second fluid docking portion 43. The outline shape of the second fluid docking portion 43 is adapted to the outline shape of the first fluid docking portion 14. The inner bottom of the second fluid docking portion 43 has a mesh wall 431. The mesh wall 431 has multiple air outlet holes 432. When the dust cup 4 is installed in the receiving chamber 11, the air inlet 133 is fluidly connected to the dust-laden airflow inlet 461; the first fluid docking portion 14 and the second fluid docking portion 43 of the cup bottom 42 are fluidly connected.

[0035] A HEPA filter 44 can be further installed inside the second fluid docking section 43 for final high-efficiency filtration. In terms of the airflow direction leaving the gas-solid separation chamber 41, the HEPA filter 44 is located downstream of the air outlet 432.

[0036] like Figure 6As shown, when the dust cup 4 is installed in the receiving chamber 11, the second fluid docking part 43 (concave structure) of the dust cup 4 is fitted downwards onto the outside of the first fluid docking part 14 (convex structure) of the base 1 and the waterproof cover 3. At this time, the waterproof cover 3 is exactly located between the vent hole 142 of the first fluid docking part 14 and the air outlet 432 of the second fluid docking part 43. Due to the presence of the support rib 33, the airflow 800 can smoothly flow from the air outlet 432 to the vent hole 142 through the gap 433 between the cover body 31 and the second fluid docking part 43 and the gap 34 between the cover body 31 and the first fluid docking part 14, maintaining airflow communication. At the same time, the dome-shaped waterproof cover 3 provides a guiding surface for the airflow flowing out from the upper air outlet 432.

[0037] like Figure 8 As shown, a drain outlet 131 is also provided on the side wall 13 of the base 1. The drain outlet 131 is level with or slightly lower than the bottom wall 12, forming a low point. In this way, even if a large amount of liquid is accidentally spilled into the receiving chamber 110, the liquid can be collected on the bottom wall 12 after flowing through the waterproof cover 3 and discharged from the base 1 through the drain outlet 131, further enhancing the waterproof capability and safety of the equipment.

[0038] In addition, such as Figure 5 As shown, an air venting channel 132 is formed between the inner and outer shells of the base 1. One end of this air venting channel 132 is connected to the exhaust end 22 of the suction motor 2, and the other end is open to the outside atmosphere. This design cleverly integrates the exhaust path of the suction motor into the base structure, improving the overall integrity of the product.

[0039] If necessary, a locking mechanism (not shown in the figure), such as a push-button latch or a slider lock, can be provided between the dust cup 4 and the base 1 for installation. This ensures that the dust cup 4 is securely held in the receiving chamber 11 during operation, preventing it from accidentally coming loose.

[0040] like Figure 1 and Figure 2 As shown, the dust cup 4 has a top wall 45. When the dust cup 4 is installed inside the receiving compartment 11, the top wall 45 is higher than the top surface 15 of the base 1. The top wall 45 is also provided with a recessed handle 451 for easy gripping and placement by the user. An operating interface 16, such as a power switch button and a power indicator light, can be provided on the top surface 15 of the base 1 for easy user operation.

[0041] In this example, the bottom 42 of the dust cup 4 can be configured to be openable, and is releasably connected to the lower part of the side wall 46 of the dust cup 4 via a releasable latch 421. This design allows users to clean the collected pet hair and dust directly from the bottom of the cup without having to put their hands inside, making it more hygienic and convenient.

[0042] When the user removes the dust cup 4 from the receiving compartment 11 of the base 1 for cleaning, such as Figure 8 As shown, the first fluid docking portion 14 and its vent 142 on the base 1 are exposed. However, since the waterproof cover 30 still covers the first fluid docking portion 14, its dome-shaped structure can effectively cover the vent 142 below. At this time, even if water droplets or other liquids 900 fall on the waterproof cover 30, the liquid 900 will flow along the dome surface of the waterproof cover 3 to the surrounding bottom wall 12, and will not drip or flow directly into the vent 142, thus fundamentally avoiding the risk of short circuit and burnout caused by liquid directly entering the suction motor 2.

[0043] In summary, this invention cleverly solves the safety hazard of water ingress caused by dust cup disassembly in existing technologies by placing a waterproof cover above the exposed vent. This solution is simple in structure and low in cost, and greatly improves the safety and reliability of the product without affecting normal airflow and suction function. It is particularly suitable for usage scenarios such as cleaning pet hair, which often require frequent dust cup cleaning.

[0044] Although the present invention has been described in detail through the above embodiments, those skilled in the art will understand that various changes, modifications, substitutions, and alterations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
