Detailed Description

In order that the above objects, features and advantages of the utility model will be more clearly understood, a more particular description of the utility model will be rendered by reference to the appended drawings and detailed description thereof, which are simplified schematic drawings which illustrate only the basic structure of the utility model and therefore show only those features which are relevant to the utility model, it being noted that embodiments of the utility model and features of the embodiments may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model, but the present utility model may be practiced in other ways than those described herein, and therefore the scope of the present utility model is not limited to the specific embodiments disclosed below.

Referring to fig. 1 to 3, the present disclosure provides a dust collecting device 3 for collecting dirt such as dust mites, the dust collecting device 3 including a housing 31, a guide 32 provided in the housing 31, and a filter assembly 33 provided in the guide 32.

The middle part of the shell 31 is recessed inwards, two ends of the shell 31 are respectively provided with an air outlet 311 and a sewage outlet 312, and a dust collection cavity 310 for collecting and containing dirt is formed between the middle recessed part and the sewage outlet 312 of the shell 31. The housing 31 is provided with a dirt inlet 313 at an end remote from the dust collecting chamber 310, the axis of the dirt inlet 313 is perpendicular to the axis of the housing 31, and dirt such as dust mites enters the housing 31 through the dirt inlet 313. Because the suction source sucks air to generate negative pressure in the dust collecting cavity, a vacuum area with adsorption effect is formed in the dust collecting cavity 310, so that dirt such as dust mites in the air flow entering the shell 31 from the dirt inlet 313 is automatically adsorbed in the dust collecting cavity 310.

The shell 31 is further provided with a cover 314 at the drain 312, the cover 314 is used for restricting dirt such as dust mites into the dust collecting cavity 310 of the cover 314, and the cover 314 is detachably connected with the shell 31. When the dirt such as dust mites collected in the dust collecting chamber 310 is required to be removed, the dust collecting device 3 is detached from the cleaning apparatus, the cover 314 is opened, and finally the dirt such as dust mites is removed from the drain 312.

The guide member 32 is a hollow structure, and two ends of the guide member are respectively provided with a first opening 321 and a second opening 322, wherein the first opening 321 is arranged at the air outlet 311 of the shell 31, and the second opening 322 is positioned in the shell 31 and faces the sewage drain 312. The guide 32 is further provided with a third opening 323 communicating with the dirt inlet 313, the third opening 323 being provided on a side wall of the guide 32. Preferably, the third opening 323 is provided at a portion of the guide 32 facing the dirt inlet 313. The guide 32 forms a sealed space between the portion between the first opening 321 and the second opening 322 and the inner wall of the housing 31, the sealed space being in communication with the dirt inlet 313 and the third opening 323, thereby defining that the air flow entering the housing 31 from the dirt inlet 313 can only enter the guide 32 through the third opening 323.

Further, the guide 32 includes a cylindrical body 324 and a conical body 325, wherein one end of the body 324 is provided with the first opening 321, the other end of the body 324 is connected with the open end of the body 325, the necking end of the body 325 is provided with the second opening 322, the second opening 322 is coaxial with the first opening 321, and the third opening 323 is provided on the sidewall of the body 324. Since the second opening 322 end of the guide 32 has a tapered structure, the guide 32 can prevent the dirt such as dust mites from flowing backward.

The filter assembly 33 is fitted at the first opening 321 of the guide 32 for filtering the air flow so that the clean air is discharged to the outside from the first opening 321 of the guide 32. The cross-section of the filter assembly 33 is preferably trapezoidal and includes a support 331, a first filter 332 and a second filter 333 disposed within the support 331.

The support 331 is disposed in the guide 32 and is installed at the first opening 321 of the guide 32, and the support 331 is provided with an air inlet and an air outlet, wherein the first filter 332 is disposed at the air inlet of the support 331 and the second filter 333 is disposed at the air outlet of the support 331. The first filter 332 is used to filter large particulate dirt from the airflow and the second filter 333 is used to filter fine dust from the airflow. The first filter 332 may be a filter mesh, and the second filter 333 may be HEPA. Preferably, the cross section of the HEPA is trapezoidal.

The dust collecting device 3 operates as follows: dirty air including dust mites sequentially enters the guide piece 32 from the dirt inlet 313 and the third opening 323, the airflow entering the guide piece 32 is subjected to cyclone downward action, so that solid dirt is forced to flow downwards in a rotating mode, the solid dirt enters the dust collecting cavity 310 in the shell 31 from the second opening 322, and the airflow is discharged outwards from the first opening 321 after being filtered by the filter assembly 33. Since the guide 32 has a conical taper and the second opening 322 is located at the necked-down end of the taper 325, the guide 32 can both accelerate the ingress of solid contaminants into the dust collection chamber 310 of the housing 31 and prevent the backflow of the solid contaminants, thereby improving the filtration efficiency and extending the life of the suction assembly.

As a preferred embodiment, the guide 32 further comprises a flow guide 326, the flow guide 326 being arranged at the third opening 323 of the guide 32 and between the guide 32 and the filter assembly 33, the flow guide 326 being adapted to rotate the dirty gas containing dust mites and the like in the guide 32. More preferably, the guide 32 is integral with the bracket 331 of the filter assembly 33.

Referring to fig. 4, the present disclosure also provides a cleaning apparatus comprising the above-described integrated device 3.

The cleaning device further comprises a housing 2, a handle 1 connected to one end of the housing 2, and a suction assembly fitted within the housing 2.

The top of the housing 2 is provided with an opening extending from an end of the housing 2 away from the handle 1 to an end close to the handle 1, the opening being in communication with the inner chamber of the housing 2, thereby forming a first fitting groove in communication with the outside at the top of the housing 2, and the dust collecting device 3 is detachably fitted in the first fitting groove and in communication with the suction assembly.

Further, the outer surface of the housing 31 is substantially flush with the outer surface of the casing 2, thereby making the appearance of the cleaning device as a whole neat and beautiful.

In the description of the present utility model, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art in a specific case.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present utility model. Various modifications to the embodiments described above will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the utility model. Thus, the present utility model is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
