Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner technology, and in particular to a handheld vacuum cleaner with an easy-to-clean filter cup. Background Technology

[0002] In the cleaning and maintenance of modern homes and small offices, handheld vacuum cleaners have become a popular cleaning tool due to their lightweight, portability, and flexible operation. They can easily reach furniture crevices, corners, and staircases—areas that are difficult for traditional large vacuum cleaners to access—efficiently completing the cleaning task and greatly improving the convenience and thoroughness of cleaning.

[0003] The filter cup is a key component in a vacuum cleaner, responsible for separating dust and air, and trapping debris such as dust and hair. Most existing filter cups are cylindrical or cup-shaped, creating dead zones at the bottom and sides where dust accumulates and is difficult to clean, requiring tools and increasing the user's workload. Many users prefer to rinse with water, but the bottom of the cup dries slowly, requiring a long drying time, making it difficult to store promptly and impacting customer experience. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a handheld vacuum cleaner with an easy-to-clean filter cup.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a handheld vacuum cleaner with an easy-to-clean filter cup, comprising a handheld handle, a storage battery, a suction pipe, a filter cup, and a main unit. The storage battery is located at the bottom of the handheld handle to provide power to the main unit. The main unit is located at the top of the handheld handle. The suction pipe is located at the front end of the handheld handle and has an arc-shaped mounting groove at its top. The bottom surface of the arc-shaped mounting groove near the main unit has a vent that communicates with the suction pipe cavity. The filter cup includes a cup body and a cup bottom. The cup bottom is located at the end of the cup body away from the main unit and is hinged to the cup body at its bottom and snapped to the cup body at its top. The bottom of the cup body is snapped into the arc-shaped mounting groove and has a first air inlet that communicates with the vent. The rear end of the cup body is connected to the main unit and has a filter assembly inside.

[0006] By adopting the above technical solution, a cup body and a cup bottom are designed, with the bottom of the cup bottom hinged to the cup body and the top of the cup bottom snapped to the cup body. This allows the cup bottom to be opened or closed relative to the cup body. After the vacuum cleaner finishes its work, the cup bottom can be opened for cleaning, making cleaning the cup body and the cup bottom more convenient. After rinsing with water, it can also be dried quickly, making it more convenient for customers to clean and providing a better experience.

[0007] Furthermore, the front end of the cup body is provided with a snap-fit ​​groove arranged along its length, a snap-fit ​​plate is rotatably disposed in the snap-fit ​​groove, a top spring is provided between the rear end of the snap-fit ​​plate and the bottom of the snap-fit ​​groove, a snap-fit ​​inclined block is provided on the front bottom surface, a snap-fit ​​connecting plate is provided protruding from the top of the cup bottom toward the snap-fit ​​groove, and a snap-fit ​​square groove is provided on the snap-fit ​​connecting plate, the snap-fit ​​square groove and the snap-fit ​​inclined block form a snap-fit ​​engagement.

[0008] By adopting the above technical solution, a snap-fit ​​groove, a snap-fit ​​plate, a top spring, and a snap-fit ​​wedge are set up. The top spring pushes the snap-fit ​​plate, providing a constant downward force to the snap-fit ​​wedge. A snap-fit ​​connecting plate and a snap-fit ​​square groove are also included. When the cup bottom is fastened onto the cup body, the snap-fit ​​connecting plate and the snap-fit ​​wedge form a wedge-shaped engagement, pushing the snap-fit ​​wedge upward. When the snap-fit ​​square groove moves to below the snap-fit ​​wedge, the snap-fit ​​wedge moves downward into the snap-fit ​​square groove under the action of the top spring, achieving the snap-fit. When it is necessary to open the cup bottom, simply press the rear end of the snap-fit ​​plate to compress the top spring, causing the snap-fit ​​wedge to move upward away from the snap-fit ​​square groove, thereby opening the cup bottom.

[0009] Furthermore, a hinge groove is provided at the bottom front end of the cup body, and protruding shafts are provided on both sides of the hinge groove. Two hinge connecting plates are provided on the side of the cup bottom near the cup body, protruding into the hinge groove. A groove is provided on the outer side of the hinge connecting plate to cooperate with the protruding shaft. A short shaft is provided on the inner side of the hinge connecting plate, and a torsion spring is sleeved on the short shaft. The torsion spring provides elastic force to the cup bottom away from the cup body.

[0010] By adopting the above technical solution, a hinge groove, a convex shaft, a hinge connecting plate, and a groove are set. The hinge between the cup body and the cup bottom is achieved by the cooperation of the convex shaft and the groove. Then, by setting a short shaft and a torsion spring, when the snap-fit ​​wedge block leaves the snap-fit ​​square groove, the cup bottom can be popped open under the action of the torsion spring, which is convenient to operate.

[0011] Furthermore, the filter assembly includes a filter branch pipe, one end of which is detachably disposed at the open end of the filter cup, and the other end is in sealed contact with the bottom of the filter cup. The filter branch pipe has an opening on the side wall near the main unit and is provided with an annular metal filter screen. A HEPA filter element with its opening facing the main unit is disposed inside the filter branch pipe.

[0012] By adopting the above technical solution, a metal filter and a HEPA filter are installed. Larger impurities are first filtered through the metal filter, and then smaller impurities such as dust are filtered through the HEPA filter. In this way, the dust particles contained in the air entering the fan assembly are small due to the two-layer filtration effect of the metal filter and the HEPA filter, so as not to affect the normal operation of the fan assembly.

[0013] Furthermore, the filter branch pipe includes an installation pipe disposed at the opening end of the filter cup and a support pipe that is in sealed contact with the bottom of the filter cup. The installation pipe and the support pipe are connected by several connecting plates, and a metal filter screen is disposed on the connecting plates. An arc-shaped plate protrudes from the side of the installation pipe near the support pipe and is arranged close to the metal filter screen, and a stop block is disposed on the arc-shaped plate. A baffle is disposed on the side of the arc-shaped plate away from the installation pipe. The arc-shaped plate, the stop block, the baffle, and the side of the installation pipe together form an arc-shaped air guide groove. The cavity of the arc-shaped air guide groove is connected to the first air inlet on the filter cup. A flexible baffle plate protrudes from the stop block toward the arc-shaped air guide groove to block the first air inlet.

[0014] By adopting the above technical solution, an installation pipe and a support pipe are set up. The installation pipe is used to install the filter branch pipe inside the filter cup and to install the HEPA filter element. The support pipe is used to support the metal filter screen together with the installation pipe. Furthermore, by setting up arc-shaped plates, blocks, and baffles, together with the side of the installation pipe, an arc-shaped air guide channel is formed, allowing air to enter from the arc-shaped air guide channel. In this way, under the suction of the fan assembly, the drawn-in air will carry impurities and dust around the metal filter screen, ensuring the filtration effect of the metal filter screen.

[0015] Furthermore, a sliding block is provided horizontally at the bottom of the arc-shaped mounting groove, and two vertical locking holes communicating with the arc-shaped mounting groove are arranged at intervals inside the sliding block. A wedge-shaped locking block is provided on one side of the vertical locking hole, and two buckles are correspondingly provided at the bottom of the cup body.

[0016] By adopting the above technical solution, sliding blocks, vertical locking holes, wedge-shaped locking blocks, and buckles are set up to facilitate the snap-fit ​​connection between the filter cup and the arc-shaped mounting groove.

[0017] Furthermore, the side wall of the arc-shaped mounting groove is provided with a through hole, and a button is provided on the sliding block protruding into the through hole.

[0018] By adopting the above technical solution, and setting through holes and buttons, it is easy to control the sliding block, thereby facilitating the installation and disassembly of the filter cup.

[0019] In summary, this utility model has the following beneficial effects: In this application, by setting a cup body and a cup bottom, the bottom of the cup bottom is hinged to the cup body and the top is snapped to the cup body, so that the cup bottom can be opened or closed relative to the cup body. This allows the cup bottom to be opened for cleaning after the vacuum cleaner has finished its work, making it more convenient to clean the cup body and the cup bottom. It can also be quickly dried after rinsing with water, making it more convenient for customers to clean and providing a better experience. Attached Figure Description

The metal filter 62 serves as the first line of filtration, used to filter larger particles of debris and dust. An arc-shaped plate 66 protrudes from the side of the mounting pipe near the support pipe 65, close to the metal filter 62, and a baffle 661 is set on the arc-shaped plate 66. A baffle 662 is set on the side of the arc-shaped plate 66 away from the mounting pipe. The arc-shaped plate 66, the baffle 661, the baffle 662, and the side of the mounting pipe together form an arc-shaped air guide groove 67. The cavity of the arc-shaped air guide groove 67 is connected to the first air inlet 43 on the filter cup 40, so that air enters from the arc-shaped air guide groove 67. Under the suction of the main unit 50, the sucked-in air will carry impurities and dust around the metal filter 62, ensuring the filtration effect of the metal filter 62. A flexible baffle 68 protrudes from the baffle 661 toward the arc-shaped air guide groove 67 to block the first air inlet 43. Under the suction, the flexible baffle 68 will stick to the arc-shaped air guide groove 67, so that the first air inlet 43 is opened, making it easier for impurities and dust to enter. When the main unit 50 is not working, the flexible baffle 68 blocks the first air inlet 43, preventing debris sucked into the filter cup 40 from re-entering the suction pipe 30 through the first air inlet 43, thus avoiding debris falling and affecting the cleaning effect. The HEPA filter 63 is installed inside the installation pipe, with its main body located inside the metal filter 62 and its opening facing the main unit 50. As a second line of filtration, the HEPA filter 63 filters out most of the dust, ensuring that the dust particles in the air entering the main unit 50 are small and will not affect the normal operation of the fan components.
