Description

TECHNICAL FIELD

[0001] The utility model belongs to and cleaning equipment technical field relates to a dust cup subassembly for handheld dust catcher. BACKGROUND

[0002] In the field of modern cleaning equipment, the dust catcher is widely used in various environments for cleaning work as a common cleaning tool, including cooperation with the base station to realize more convenient and efficient cleaning mode.

[0003] The traditional dust catcher has some limitations in design. The size of the filter provided is often small, which may affect the filtering effect during the dust collection process, and cannot efficiently intercept fine dust particles. At the same time, the volume of the dust cup is also small, which is easy to be filled with dust and other garbage after a regular cleaning operation, and the dust cup needs to be cleaned frequently, which undoubtedly increases the operation burden of the user and reduces the cleaning efficiency.

[0004] With the development of technology, the mode of dust catcher cooperating with base station appears. Its principle is that through the application of the base station, the garbage in the dust cup of the dust catcher can be sucked into the garbage bag of the base, thereby effectively protecting the cleaning of the dust cup in the dust catcher, so that the dust catcher can maintain good dust collection performance, and the user does not need to clean the dust cup manually frequently, which greatly improves the convenience of cleaning.

[0005] However, the dust cup structure design used on the current dust catcher still has obvious defects. In actual use, especially when cleaning the area with hair, the hair is easy to entangle on the filter. The existing base station cooperating with the dust catcher system cannot effectively suck the hair entangled on the filter into the base. This not only causes the blockage of the filter, affects the dust collection effect and the service life of the equipment, but also makes the user have to clean the entangled hair manually, and cannot fully play the high efficient cleaning advantage of the base station cooperating with the dust catcher.

EMBODIMENT

[0033] Referring to Figures 1-6 As shown in the figure, a dust cup assembly includes a cup body 1 and a filter 2 installed in the cup body 1. The cup body 1 has a containing space, and the cup body 1 is provided with an import 11 communicating with the containing space. The filter 2 is at least partially disposed in the containing space, and the filter 2 includes a filter support 21 installed on the cup body 1, and a hepa assembly 22 disposed in the filter support 21. The filter support 21 includes a support main body 211 and a support piece 212, and the support main body 211 and the support piece 212 are fixedly connected through a support rod 213 to form a hollow area therebetween. The outer end surface of the support piece 212 is a circular arc surface that is wide at the top and narrow at the bottom. The hollow area between the support piece 212 and the support main body 211 is covered with a filter screen 23. The outer end surface of the support main body 211 is provided with a cyclone cone 2111 corresponding to the import 11.

[0034] In the design of the dust cup assembly, the cyclone cone plays a role in guiding the airflow. Its edge closely fits the lower edge of the inlet 11, forming the first line of defense and guidance. At the same time, the support body located at the narrow part of the cyclone cone also closely fits one side of the inlet 11. Through such a close-fitting design, the airflow and debris entering from the inlet 11 can be effectively constrained.

[0035] The cyclone cone 2111 is ingeniously configured to allow debris to smoothly enter the containing space from the inlet 11, and after entering, the debris will move downward along the landslide of the cyclone cone. When the vacuum cleaner is working, the airflow carrying dust and other debris flows into the inlet 11, and under the action of the cyclone cone, the debris will rapidly rotate downward along the slope of the cyclone due to the centrifugal force of the cyclone, achieving preliminary separation of the debris.

[0036] In use, dust and other debris from the outside enters from the inlet 11 and forms a cyclone-shaped airflow in the containing space along the path of the cyclone cone 2111. Air passes through the filter screen 23 and is discharged from the outlet of the hepa assembly 22, and dust and other debris are blocked by the filter screen 23 and fall into the dust outlet below the cup body 1 under the action of centrifugal force. Because the support 212 adopts a circular arc surface, long hair and other long objects cannot be entangled on the support 212, which helps to better guide the flow direction of the airflow and dust, and avoids hair entanglement causing filter blockage.

[0037] In the dust cup assembly, the support 212 is the core improvement point of the present application. Its outer end face is a unique hemispherical structure, which makes the outer end face of the support 212 have a smooth and rounded curved surface. During the dust collection process, when the airflow carrying dust and other debris passes through this place, it can change the flow direction more smoothly, effectively reduce the airflow resistance, and make the dust more smoothly enter the subsequent link. At the same time, the hemispherical structure also avoids the entanglement of dust or hair and other foreign matter to some extent, avoiding hair entanglement causing filter blockage.

[0038] Further, in order to avoid the accumulation of dust and other debris at the junction of the filter screen 23 and the support 212, the present embodiment is provided with a clamping groove at the upper end of the support 212, and the bottom edge of the filter screen 23 is arranged in the clamping groove, so as to realize the close connection of the two. And the support outside the clamping groove can closely fit on the filter screen 23, further enhancing the tightness of the connection.

[0039] Meanwhile, in order to better guide the dust and other sundries to pass through the joint smoothly and avoid the situation of jamming and accumulation, the upper end face of the support outside the clamping groove is designed as an inclined downward guide curve or guide slope. When the dust flows through this place during the dust collection process, under the action of the guide curve or slope, the dust and other sundries can flow smoothly downward along the inclined direction, thereby ensuring that there is no problem of excessive accumulation of sundries and entanglement of hair at this place, and the dust collection and filtering process of the entire dust cup assembly is not hindered, and always maintains a high-efficiency and stable running state.

[0040] In order to prevent hair and the like from being entangled on the filter 2, the outer diameter of the filter screen 23 below the cyclone cone 2111 and the support 212 gradually decreases in the direction from top to bottom. In cooperation with the support 212 with a hemispherical structure, the entanglement of hair on the filter can be effectively avoided during dust-gas separation.

[0041] The cup body 1 in the dust cup assembly is composed of a base 12 and an outer cover 13. The outer cover 13 is stably connected to the base 12 by clamping, which is convenient for assembly and can ensure the sealing of the overall structure. The inlet 11 is provided on the outer cover and is an inlet passage for dust and other sundries to enter the dust cup.

[0042] A boss 131 is designed inside the outer cover 13 above the inlet 11, which mainly provides a space for the filter support 21 to be placed, and ensures that the filter support 21 can be accurately and stably installed at a suitable position in the dust cup to play its filtering function. In order to prevent air from escaping from the gap between the outer cover and the filter support, a sealing groove is provided at the upper end of the filter support 21, and a sealing ring is arranged in the sealing groove, and the outer edge of the sealing ring tightly fits on the inner wall of the outer cover 13.

[0043] The bottom of the base 12 is provided with a dust discharge port, which is an outlet for cleaning the accumulated dust in the dust cup. In order to prevent dust from leaking in the non-cleaning state, a bottom cover 14 is also provided at the dust discharge port, which can tightly close the dust discharge port and ensure that the dust in the dust cup does not leak out from the bottom during normal use, thereby maintaining the good dust collection and dust collection performance of the dust cup assembly. The opening and closing of the bottom cover 14 is controlled by a locking structure provided on the cup body. The above-mentioned locking structure is a prior art and can realize the opening and closing action of the bottom cover.

[0044] In the design of the dust cup assembly, the bottom of the filter 2 is in a suspended setting state relative to the bottom cover 14. Such a setting mode makes a certain interval exist between the filter 2 and the bottom cover 14, which is convenient for the dust to be smoothly deposited downward after being filtered by the filter 2.

[0045] The inner cavity of the base above the bottom cover 14 is set as a dust storage space. When dust enters the dust cup through the inlet 11 and is filtered by the filter 2, the dust particles and other impurities that cannot pass through the filter will fall into the dust storage space for storage, until the bottom cover 14 is opened for subsequent cleaning, and the stored dust is discharged, so that the dust cup assembly can continuously and effectively perform dust suction and collection.

[0046] The hepa assembly 22 in the dust cup assembly plays a filtering role. The hepa assembly 22 includes a hepa bracket and a hepa, and the hepa is arranged on the hepa bracket. A clamping groove is arranged on the periphery of the hepa bracket. At the same time, a protrusion is correspondingly arranged on the filter bracket. When the hepa bracket needs to be installed on the filter bracket, the clamping groove can be accurately rotated into the protrusion by rotating the hepa bracket. In this way, the hepa assembly 22 can be quickly installed.

[0047] The structure of the support member is improved from the original columnar structure to the arc surface structure. When the dust collector starts to work, the arc surface support member plays a significant advantage when the dust and other impurities move downward with the cyclone. The smooth surface can guide the dirt to enter the dust storage space downward along the movement track of the dirt, ensuring efficient collection of dust and other impurities.

[0048] Especially important is that this arc surface structure effectively avoids the problems that are prone to occur in the previous columnar structure. During cleaning, hair often wraps around the support member, causing the filter to be blocked and affecting the dust suction and filtering effect. The improved arc surface support member greatly reduces the possibility of hair wrapping, maintains the smoothness of the filter, ensures the continuous and stable operation of the entire dust cup assembly, and improves the use performance of the cleaning device.
