Description

Technical Field

[0001] This utility model relates to the field of cleaning, and in particular to a handheld cleaning device that can scrape off dust. Background Technology

[0002] Currently, handheld cleaning devices consist of a dustbin, a main body fixedly connected to the dustbin, and a vacuum source located within the main body that creates a vacuum inside the dustbin. Existing dustbin structures mainly include a cyclone-generating body and a filter assembly located within the body. The drawback of this structure is that large dust particles easily enter the filter assembly, clogging the mesh and affecting the vacuum cleaner's filtration performance. To address this, the applicant previously employed multiple guide vanes to direct large dust particles to the bottom of the dustbin, preventing them from entering the filter assembly. A similar technology can be found in Chinese Utility Model Patent CN208447456U. While this technology utilizes guide vanes, some large dust particles may still clog the mesh if not properly guided. Furthermore, prolonged use can lead to excessive dust accumulation at the bottom of the dustbin, also causing mesh clogging. Utility Model Content

The transmission member body 3620 includes an elastic fixing post 3624 at one end and a fixing hole 3626 adjacent to the elastic fixing post 3624. The pushing member actuating portion 3440 reciprocates within the transmission member mating groove 3664, and the transmission member body 3620 is provided with a body mating groove 3628 communicating with the fixing hole 3626. This embodiment includes a second elastic member 3940 sleeved on the elastic fixing post 3624, wherein the elastic force generated by the second elastic member 3940 is greater than the elastic force generated by the first elastic member 3900. The first elastic element 3900 and the second elastic element 3940 are preferably springs, and the wire diameter, coil spacing and outer diameter of the second elastic element 3940 are all greater than the wire diameter, coil spacing and outer diameter of the first elastic element 3900. The actuating component 3800 includes an actuating component body 3820 with an arc-shaped cross-section and an actuating component protrusion 3840 located inside the actuating component body 3820 and correspondingly engaging with the body mating groove 3628. The outer side of the actuating component body 3820 contacts the user's hand. The actuating component protrusion 3840 is provided with a protrusion mating hole 3844 corresponding to the fixing hole 3626. In this embodiment, a screw passes through the protrusion mating hole 3844 and is fixed to the fixing hole 3626 to achieve a fixed connection between the actuating component 3800 and the conductive component 3600. The dustbin 1000 also includes a dustbin inlet 1024 communicating with the dustbin cavity 1020, while the scraper component 3200 includes a baffle 3280 that can cover the dustbin inlet 1024 and is rotatably connected to the scraper frame 3220. The scraper ring 3260 and the scraper frame 3220 are made of different materials and are integrally molded. The scraper ring 3260 is preferably made of soft rubber, while the scraper frame 3220 is preferably made of hard rubber, and the scraper ring 3260 is formed by injection molding. The vacuum source 4000 is preferably a brushless DC motor. When the handheld cleaning device in this embodiment is placed on a horizontal plane, the center direction of the vacuum source 4000 is parallel to the horizontal plane. The power module 5000 is preferably a rechargeable battery, more preferably a lithium battery or a nickel-metal hydride battery, and the bottom of the power module 5000 is a flat surface that can be placed on the horizontal surface. During operation, the vacuum source 4000 drives the impeller to rotate at high speed, thereby generating negative pressure in the dust bin chamber 1020. Under the action of negative pressure, the dust-laden airflow flows in from the inlet end of the air inlet pipe 2240 and then flows out from the outlet end of the air inlet pipe 2240. Then, it enters the dust bin chamber 1020 through the dust bin inlet 1024 to generate a primary cyclone. After being separated by the cyclone, the airflow containing fine dust passes through the filter screen 1220 and continues to enter the secondary cyclone separator 1240 for secondary cyclone. The airflow after the secondary cyclone passes through the pre-filter on the front side of the vacuum source 4000 for further filtration, and then enters the vacuum source 4000 before finally being discharged to the outside. When excessive dust accumulates on the filter 1220, the user holds the actuating element 3800 and moves it towards the inlet end of the air inlet pipe 2240, thereby compressing the second elastic element 3940. Simultaneously, this causes the transmission element 3600 to move, and the transmission element's mating groove 3664 further drives the pushing element's actuating part 3440 to move. Then, the pushing element's receiving part 3460 compresses the first elastic element 3900, while the first guide post 3500 pushes the dust scraper 3200 to move. The dust scraper ring 3260 thus scrapes the dust off the filter 1220. Because this embodiment uses two elastic elements, operation is more reliable, and the user's hand grip allows for greater force and smoother dust scraping, rather than finger flicking, thus avoiding excessive resistance during operation and potential finger injury. The advantages of this invention are: it prevents large dust particles from clogging the mesh, improves the filtration performance of the vacuum cleaner, and adopts a manual grip method instead of finger flicking, making it easier to scrape dust and ensuring reliable operation. Of course, the above embodiments are only for illustrating the technical concept and features of this utility model, and their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent transformations or modifications made in accordance with the spirit and essence of the main technical solution of this utility model should be covered within the protection scope of this utility model.
