Detailed implementation manners

[0025] Next, in combination with the detailed implementation manners, the present application will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined with each other to form new embodiments.

[0026] In the description of the present application, it should be noted that for orientation terms, such as the terms "center", "horizontal", "vertical", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation and positional relationship are based on the orientation or positional relationship shown in the drawings. This is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of the present application.

[0027] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects and do not necessarily need to describe a specific order or sequence.

[0028] The terms "comprising" and "having" in the description and claims of the present application, and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products, or devices.

[0029] The present application provides a dust cup, as Figures 1 - 3 shown, which includes a cover body 10 and a cup body 20. The cover body 10 and the cup body 20 are buckled with each other to form a relatively airtight cavity. The cup body 20 is provided with an air extraction port and a dust suction port communicating with the cavity. A filter assembly 40 and a HEPA assembly 50 are installed in the cavity. The relative positions of the cover body 10 and the cup body 20 are locked through a locking structure 30. When it is necessary to pour out the garbage in the dust cup, the locking structure 30 can be unlocked, and the cover body 10 can be removed to pour the cup body 20.

[0030] Among them, the filter assembly 40 generally includes a filter bracket 41 and a filter screen 42. The filter screen 42 is installed on the filter bracket 41, and the HEPA assembly 50 is installed inside the filter bracket 41.

[0031] Generally, the dust cup is detachably arranged on the cleaning device. In order to ensure the dust suction effect of the cleaning device, the user will remove the dust cup and disassemble the filter assembly 40 and the HEPA assembly 50 in the cavity for cleaning. After the filter assembly 40 and the HEPA assembly 50 are dried, they are reinstalled into the dust cup. However, in the existing cleaning device, it is easy to forget to reinstall the HEPA assembly 50 during use. At this time, starting the cleaning device will cause dust to be discharged into the air and pollute the air. The dust may affect the operation of the motor and even cause the motor to burn out. To solve this problem, the present application provides a HEPA anti-missing installation structure.

[0032] A Hepa anti-missing installation structure, as Figures 2 - 8 shown, which includes a cover body 10, a Hepa component 50, and a filter screen bracket 41. The filter screen bracket 41 is provided with an installation cavity 401. The Hepa component 50 is arranged in the installation cavity 401. One end of the Hepa component 50 abuts against the filter screen bracket 41, and the other opposite end is detachably connected to the filter screen bracket 41 and detachably connected to the cover body 10. First of all, the filter screen bracket 41 is installed on the cover body 10 of the dust cup through the Hepa component 50, which can play a role in preventing the Hepa from being missing, and further prevent poor air quality and motor burnout caused by directly using the cleaning equipment without installing the Hepa. In addition, the Hepa component 50 is detachably connected to both the filter screen bracket 41 and the cover body 10, so as to facilitate the cleaning and maintenance of the Hepa component 50 and the filter screen bracket 41. Moreover, the whole Hepa anti-missing installation structure is simple in structure, low in processing and production cost, and convenient to use.

[0033] In some embodiments, the Hepa component 50 includes a Hepa filter element 52, a Hepa upper cover 51, and a Hepa lower cover 53. One end of the Hepa filter element 52 is connected to the Hepa upper cover 51, and the other end is connected to the Hepa lower cover 53. The Hepa upper cover 51 is detachably connected to the filter screen bracket 41 and the cover body 10, and the Hepa lower cover 53 abuts against the filter screen bracket 41. The Hepa upper cover 51 and the Hepa lower cover 53 can provide the functions of supporting and positioning the Hepa filter element 52, and provide the structure for connecting to the filter screen bracket 41 and the cover body 10. Specifically, glue can be applied between the Hepa lower cover 53 and the Hepa filter element 52 for fixation.

[0034] In some embodiments, the Hepa upper cover 51 is connected to both the filter screen bracket 41 and the cover body 10 by a screwing connection method. The operation is simple during disassembly and assembly. And the rotation direction when the filter screen bracket 41 is connected to the Hepa upper cover 51 is the same as the connection direction when the Hepa upper cover 51 is connected to the cover body 10, so as to reduce the disassembly and assembly difficulty and avoid misoperation caused by inconsistent rotation directions.

[0035] Specifically, in some embodiments, one of the HEPA upper cover 51 and the filter bracket 41 is provided with a first slot 511, and the other is provided with a first buckle 411, a first positioning portion 513 is provided in the first slot 511, and the first buckle 411 is suitable for entering the first slot 511 along a direction parallel to the axial direction of the installation cavity 401, and rotating along a direction parallel to the circumference of the installation cavity 401 until one end of the first slot 511 is fixed by the first positioning portion 513; one of the HEPA upper cover 51 and the cover body 10 is provided with a second slot 512, and the other is provided with a second buckle 121, a second positioning portion 514 is provided in the second slot 512, and the second buckle 121 is suitable for entering the second slot 512 along a direction parallel to the axial direction of the installation cavity 401, and rotating along a direction parallel to the circumference of the installation cavity 401 until one end of the second slot 512 is fixed by the second positioning portion 514. The connection structure is simple and the processing and manufacturing cost is low. Of course, in other embodiments, other methods of screw connection may be used, such as threaded connection.

[0036] In some embodiments, the first card slot 511 and the second card slot 512 are both provided on the HEPA upper cover 51 and are interconnected. The inner side of the HEPA upper cover 51 is provided with a first recess 515, and the outer side is provided with a second recess 516. The first buckle 411 is adapted to slide upward from the first recess 515 into the first card slot 511, and the second buckle 121 is adapted to slide downward from the second recess 516 into the second card slot 512. The first positioning portion 513 is arranged opposite to the second recess 516, and the second positioning portion 514 is arranged opposite to the first recess 515. The arrangement of the first recess 515 and the second recess 516 provides a space for the first buckle 411 or the second buckle 121 to avoid, so that the corresponding buckle is easier to enter the corresponding card slot, reducing the deformation amount required when the buckle is inserted into the card slot, and helping to reduce the resistance during the screwing.

[0037] Specifically, the positioning portion is configured as a protrusion or a groove, and a corresponding concave-convex structure is provided on the buckle. When the buckle is screwed into place, it automatically snaps into the positioning portion. The setting of the positioning portion can not only lock the buckle position, but also make the buckle produce a click feeling or make a sound when it is in place, so as to prompt that it has been installed in place.

[0038] In some embodiments, a plurality of first card slots 511 are provided and are spaced around the direction parallel to the circumference of the installation cavity 401, and a plurality of second card slots 512 are provided and are spaced around the direction parallel to the circumference of the installation cavity 401 to improve the stability of the connection structure. Here, a plurality refers to two or more. In a specific embodiment, three first card slots 511 are provided.

[0039] In some embodiments, the HEPA upper cover 51 is provided with a handle portion 517 protruding away from the HEPA filter element 52. When screwing, the rotation of the HEPA upper cover 51 can be controlled by the handle portion 517, which is easy to operate.

[0040] In some embodiments, the cover 10 is of an integral structure or a split structure. In a specific embodiment, the cover 10 is of a split structure, including an outer cover 11 and an inner cover 12. The inner cover 12 can be first screwed with the Hepa assembly 50, and then the inner cover 12 and the outer cover 11 are detachably connected, which is beneficial to the operation of the screwing connection and is conducive to reducing the processing difficulty of the cover 10 compared with the integral cover 10.

[0041] In some embodiments, a first seal 61 is provided between the Hepa assembly 50 and the filter screen support 41. Specifically, an EVA seal can be provided between the lower Hepa cover 53 and the bottom of the filter screen support 41. A second seal 62 is provided between the Hepa assembly 50 and the cover 10. Specifically, an EVA seal can be provided between the top of the upper Hepa cover 51 and the cover 10, and the EVA seal extends directly above the first card slot 511 and the second card slot 512 to improve the sealing performance at the card slots. The seal can prevent dust from being discharged through the gaps of the connection structure without being filtered.

[0042] The present application can also provide a cleaning device applying any of the above-mentioned Hepa anti-misloading structures or the above-mentioned dust cup, which has the characteristics of preventing Hepa misloading and more reliable filtering effect. Specifically, the cleaning device can be a mite remover or a vacuum cleaner.
