Referring to fig. 1 to 4, the cleaning device provided in the embodiment of the present application may be a handheld vacuum cleaner, or may be an upright vacuum cleaner, a horizontal vacuum cleaner, or the like. The cleaning device provided by the embodiment of the application comprises a main machine 10, a dust barrel 60 and a filter 20.

Specifically, the main unit 10 may be configured to accommodate the airflow generating device 30 therein, the main unit 10 may have an air inlet duct 40 thereon, the air inlet duct 40 may serve as a main unit air inlet S1 of the main unit 10, the main unit 10 may further have a main unit air outlet S2, and an airflow channel through which the airflow sucked by the air inlet duct 40 flows may be formed in the main unit 10. The setting position of the host air outlet S2 on the host 10 is not limited, and the host air outlet can be specifically arranged according to actual requirements. In some embodiments, the host air outlet S2 may be close to some heat generating components in the host 10, so as to dissipate heat of the heat generating components, thereby quickly and effectively reducing the temperature rise of the heat generating components. For example, the host outlet S2 is close to the battery in the host 10, so as to cool the battery. Of course, as shown in fig. 2, the host outlet S2 may have a certain distance from the battery 80 in the host 10, and the embodiment of the present invention is not limited thereto.

The air flow generating device 30 may include a rotary power device such as a motor and an impeller connected to the motor, or the air flow generating device 30 may be a bladeless air flow generating device as long as it can generate a suction air flow in a predetermined direction in the air flow passage.

The air inlet duct 40 of the main unit 10 is used to suck dust and foreign substances, which enter the main unit 10 along with the airflow. The main body 10 may have a dust-air separating device 50 and a dust bucket 60 therein, and the dust-air separating device 50 is communicated with the dust bucket 60. The dust and air drawn from the air inlet duct 40 may first pass through the dust and air separating device 50, such that most of the dust and impurities are collected in the dust barrel 60, and another small portion of the dust may flow toward the main air outlet S2 along with the air flow, since some dust is carried in the air flow, the dust is prevented from excessively adhering to the inner wall of the main unit 10 and the parts inside the main unit 10. Therefore, the filter 20 described above may be provided in the air flow passage to filter dust in the air flow. The embodiment of the present application mainly improves the layout of the filter 20 in the host 10, so that the layout of the filter 20 is more reasonable, and the user experience is better.

The filter 20 is arranged in the airflow channel, the filter 20 is cylindrical, the longitudinal axis of the filter 20 is arranged in a cross way with the height direction of the main machine 10, and at least part of the filter 20 is positioned above the dust barrel 60. It should be noted that, in the embodiment of the present application, at least a portion of the filter 20 is located above the dust bucket 60 and is bounded by the area defined by the cross section of the dust bucket 60, and at least a portion of the filter 20 is located above the area defined by the cross section of the dust bucket 60. That is, the filter 20 has a projection on the dust bucket 60 in the height direction of the main body 10.

The filter 20 is cylindrical, which means that the filter 20 is a hollow cylinder with at least one open end, but is not limited to a hollow cylinder, and the cross section is not limited to a circle, for example, the cross section may also be square, triangular, etc., and the embodiment of the present invention is not limited thereto.

The height direction of the main unit 10 described in the embodiment of the present application refers to the structural height direction of the main unit 10 in the upright state of the cleaning apparatus. And the longitudinal axis of the filter 20 refers to the central axis in the longitudinal direction of the filter 20. And "crossed" includes any angle greater than 0 deg. and may be coplanar or non-coplanar. Specifically, the lines along which the longitudinal axis of the filter 20 and the structural height of the main body 10 are aligned may be coplanar or coplanar.

The filter 20 comprises an air inlet 21 and a filter chamber 23, suction airflow generated by the operation of the cleaning equipment enters the filter chamber 23 from the air inlet 21 and is discharged after being filtered by the chamber wall of the filter chamber 23, and an air outlet 22 is formed at an aperture on the chamber wall of the filter 20. That is, the filter 20 is the inner side air inlet, the outer side air outlet, and the dust filtered by the filter 20 adheres to the inner side chamber wall of the filter chamber 23, so that even in the process that the user detaches the filter 20 from the host computer 10, the dust is not easy to drop from the filter 20 because the dust adheres to the inner side chamber wall of the filter chamber 23 of the filter 20. Also, in the present embodiment, since the longitudinal axis of the filter 20 is disposed to intersect the height direction of the main unit 10, the longitudinal axis of the filter 20 is not parallel to the height direction of the main unit 10, that is, the filter 20 is not vertically disposed. Thus, even if dust inside the filter 20 drops during the process of taking out the filter 20, some of the dust drops at other positions on the inner side wall of the filter 20. The amount of dust in the filter 20 that falls out of the end can be reduced to some extent compared to when the filter 20 is placed vertically.

In some embodiments, the longitudinal axis of the filter 20 may be perpendicular to the height direction of the main body 10, so that even if dust inside the filter 20 falls, most of the dust falls at other positions of the inner side wall of the filter 20 and rarely falls out of the end of the filter 20 during the process of taking out the filter 20. Therefore, the possibility that dust falls and spills in the process of taking the filter 20 out of the host 10 can be greatly reduced, and the user experience is effectively improved.

On the other hand, when the longitudinal axis of the filter 20 is perpendicular to the height direction of the main unit 10, the whole filter 20 is in a transverse layout state, the filter 20 in the transverse layout occupies less height space of the main unit 10 on the main unit 10, and the whole layout is reasonable and compact. The filter 20 can be disposed above the dust-gas separating device 50, and due to the transverse arrangement of the filter 20, the airflow after dust-gas separation can enter the filter cavity 23 of the filter 20 from the two ends of the filter 20 respectively in a more balanced manner.

The cleaning device that this application embodiment provided includes host computer and filter, has airflow channel in the host computer, and the filter is the tube-shape, and the vertical axis of filter sets up with the direction of height cross of host computer for the filter is not along vertical placing. The filter comprises an air inlet and a filter cavity, and air flow enters the filter cavity from the air inlet, is filtered by the cavity wall of the filter cavity and then is discharged. Because the filter adopts the mode of inboard air inlet, outside air-out for the dust is the inboard of adhesion at the filter, and the non-vertical placing of filter, can be so that the in-process of taking out the filter from the host computer, the difficult both ends of following the filter of tube-shape of the inboard dust of filter fall out, and then the reduction can effectively improve the in-process of taking out the filter, the dust on the filter problem that drops.

In the embodiment of the present application, the intake vent 21 may include at least two, as shown in fig. 3 and 4, at least two intake vents 21 may be respectively located at both ends of the filter 20, and the air flow enters the filter 20 at least from both ends of the filter 20, because the longitudinal length of the filter 20 is longer than the transverse length. Therefore, the flow path of the air flow entering the inside of the filter 20 from the end of the filter 20 is longer, and the dust in the air flow is more likely to be uniformly attached to the wall of the chamber inside the filter 20.

In the embodiment of the present application, the air inlet 21 includes at least two air inlets, which means that the air inlets 21 can be respectively disposed at least two different positions of the filter 20. By arranging at least two air inlets 21, the air inlet area can be effectively increased, the air inlet quantity is ensured, the airflow flow is increased, and the dust collection efficiency of the dust collector is improved.

And at least two air inlets 21 can be oppositely arranged, and the at least two air inlets 21 which are oppositely arranged are arranged on one cylindrical filter 20, so that the air inlets 21 of the filter 20 are reasonably arranged.

Of course, as an alternative, in other embodiments, the number of the air inlets 21 may be one, and one air inlet 21 may be located at the end of one of the ends of the filter 20.

In some embodiments, as shown in FIG. 2, filter 20 may be removably attached to host 10, with the direction of removal of filter 20 from host 10 being perpendicular to the longitudinal axis of filter 20. The filter 20 is detachably connected with the main unit 10, so that the filter 20 can be conveniently detached from the main unit 10 and can be cleaned independently, and the detaching direction of the filter 20 taken out from the main unit 10 is perpendicular to the longitudinal axis of the filter 20, so that the acting force applied to the two ends of the filter 20 by a user can be basically the same in the detaching process, and the stress balance of the filter 20 in the detaching process of the filter 20 is further facilitated.

The main body 10 has a mounting opening C, the filter 20 has a handle C1, the handle C1 can be detachably mounted at the mounting opening C, and the handle C1 seals and blocks the mounting opening C. In an exemplary embodiment, as shown in fig. 1, the edge of the handle C1 may protrude away from the mounting opening C to form a flange C11, the flange C11 may be formed to surround and form a hole expansion, and the user may grasp or pinch the flange C11 to remove the handle C1 together with the filter 20. In the embodiment of the present application, the shape of the handle C1 is not limited, for example, in the installation state, the handle C1 may be substantially rectangular, circular, regular hexagon, etc., and those skilled in the art can design the handle as needed. This application embodiment is through setting up handle C1 for handle C1 can enough play the decoration effect, in order to shelter from filter 20, avoids filter 20 to expose.

The handle C1 is detachably connected with the main machine 10, and a user can directly detach the handle C1 together with the filter 20 from the main machine 10, and also can install the handle C1 together with the filter 20 into the main machine 10, so that the dismounting efficiency can be effectively improved. And the handle C1 is connected with the main machine 10 in a sealing way to seal and close the mounting opening C, so that the air flow entering the filter 20 is the air flow sucked from the air inlet pipeline 40 when the cleaning device is in a cleaning working state, a unique air flow path is defined, and the use reliability of the cleaning device is ensured.

In addition, in order to realize that the handle C1 can seal and block the mounting opening C, in some embodiments, the handle C1 may have a first sealing ring C12 thereon, and the first sealing ring C12 may be located on a side of the handle C1 close to the filter 20. The first sealing ring C12 is adapted to be in abutting contact with a side wall of the main body 10 at the mounting opening C to achieve sealing and prevent air flow from entering the filter 20 at the mounting opening C.

In order to achieve the fixed connection between the handle C1 and the filter 20, specifically, as shown in fig. 4, the filter 20 may include a filter element 20a, and a support frame 20b for mounting the filter element 20a, wherein the filter element 20a may be filter cotton or a filter net, and the support frame 20b may be used for defining or maintaining the contour shape of the filter element 20a and preventing the filter element 20a from being deformed. The handle C1 may be integrally formed with the support frame 20b of the filter 20, for example, the support frame 20b and the handle C1 are both made of plastic, and after the two are integrally formed, the filter element 20a is installed at the support frame 20b, for example, the filter element 20a is adhered to the support frame 20 b. Alternatively, the support frame 20b and the handle C1 may be bonded together, and the support frame 20b and the handle C1 may be formed separately and then bonded together by an adhesive. Of course, the fixing manner of the filter 20 and the handle C1 is not limited to the above description, and those skilled in the art can select it according to actual situations. It can be understood that when the support frame 20b of the filter 20 is integrally formed with the handle C1, the production efficiency can be effectively improved. In particular, since the filter 20 needs to be fixed to the main body 10, interference may occur between the filter 20 and the main body 10 to prevent the filter 20 from being pulled out during the process of pulling out the filter 20, and the stability of the connection between the handle C1 and the filter 20 is particularly important, and the structural stability of the filter 20 and the handle C1 can be effectively ensured by integrally forming the support frame 20b of the filter 20 and the handle C1, and the two are not easily separated.

In some alternative embodiments, handle C1 may be provided separately from filter 20. When the handle C1 is detached from the main unit 10, the filter 20 is not removed together with the handle C1, but the filter 20 needs to be additionally removed. In this way, the filter 20 and the handle C1 are formed separately, reducing the difficulty of processing.

In view of the above, whether the handle C1 and the filter 20 have a connection relationship, and the specific fixing manner can be designed according to actual requirements, and the embodiment of the present application is not particularly limited. In the embodiment of the present application, the cleaning device may further include an airflow generating device 30, and the filter 20 may be located between the air inlet duct 40 and the airflow generating device 30 in the airflow flowing direction of the cleaning device. The airflow generating device 30 usually includes a power device such as a motor, and the cleaning device can accumulate more dust at the airflow generating device 30 when working for a long period of time, and then can affect the rotation power of the airflow generating device 30 to a certain extent, even make the airflow generating device 30 generate a clamping stagnation phenomenon, which results in a shortened service life of the airflow generating device 30 or an increased maintenance cost thereof. The cleaning equipment provided by the embodiment of the application, the filter 20 is arranged in front of the airflow generating device 30, so that the filter 20 can filter dust earlier, the airflow entering the airflow generating device 30 is the airflow filtered by the filter 20, the dust contained in the airflow is less, the excessive dust can be effectively prevented from remaining in the host 10 to damage the airflow generating device 30, the service life of the airflow generating device 30 is prolonged, and the maintenance cost is reduced.

Additionally, the axis of the airflow generating device 30 may be perpendicular to the longitudinal axis of the filter 20. In the embodiment of the present application, the axis of the airflow generating device 30 may extend substantially along the length direction of the main body 10, and the longitudinal axis of the filter 20 may extend along the width direction of the main body 10, so that the axis of the airflow generating device 30 is perpendicular to the longitudinal axis of the filter 20, and the layout of the filter 20 and the airflow generating device 30 on the main body 10 is more reasonable. Further, the extension line of the motor axis may pass through the center line of the filter 20, so that the motor and the filter 20 are disposed on the main unit 10 with better structural symmetry.

In one embodiment, the airflow generating device 30 may include a motor and an impeller connected to an output shaft of the motor, and an axis of the airflow generating device 30 may be understood as an axis of the motor.

As shown in fig. 2, at least a portion of the airflow generating device 30 may be located above the dirt cup 60. The position of the airflow generating device 30 is close to the dust barrel 60 and the air inlet pipeline 40, the whole structure is compact in arrangement, and the size of the whole machine is effectively reduced. Further, as shown in fig. 2, the method further includes: the cleaning device may further include a post-filter 90, the filter 20, the airflow generating device 30, and the post-filter 90 are sequentially arranged along the airflow flowing direction of the cleaning device, and the filter 90, the airflow generating device 30, and the post-filter 90 at least partially overlap in the height direction of the main body 10. Wherein, rearmounted filter 90 can be with the position department that host computer air outlet S2 corresponds, and rearmounted filter 90 also can be for crossing the filter pulp and make, further purifies the filtration through rearmounted filter 90 to the air-out of whole machine to avoid carrying the air discharge of more dust to the external world, improve the cleanliness factor of cleaning equipment complete machine air-out, improve user experience.

In addition, since the filter 20, the airflow generating device 30, and the post-filter 90 are at least partially overlapped in the height direction of the main unit 10, the height of the main unit 10 can be effectively reduced, which is further advantageous for the miniaturization of the whole apparatus and the improvement of the portability and the storability of the whole apparatus.

Further, as shown in fig. 1 and 2, the main body 10 is provided with an air inlet duct 40 for sucking air; the mounting opening C coincides with the orientation of the intake duct 40. Because the air inlet duct 40 is generally positioned right in front of the main machine 10, and the orientation of the mounting opening C of the filter 20 is consistent with that of the air inlet duct 40, the main machine 10 has better structural symmetry in the width direction, the outer contour of the cleaning equipment is more regular in appearance, and the structural compactness of the cleaning equipment is improved. In some application scenarios, the air inlet duct 40 may be used to connect accessories such as a ground brush, and the ground brush is usually detachably connected to the air inlet duct 40, so that the air inlet duct 40 can be connected to different types of accessories to meet different use environments, thereby improving the flexibility of the cleaning device. And the orientation of the mounting opening C of the filter 20 is consistent with the orientation of the air inlet pipeline 40, so that the operation of taking out the filter 20 and replacing the accessories of the air inlet pipeline 40 by a user can be along the same direction, and the use habit of the user can be further met.

Furthermore, the main unit 10 is further provided with a holding portion 70, the holding portion 70 and the air inlet duct 40 are located on two sides of the main unit 10 facing away from each other, and since the air inlet duct 40 and the mounting opening C are oriented in the same direction, when a user detaches the accessory and/or the filter 20 on the air inlet duct 40, the user can hold the holding portion 70 with one hand and pull out the accessory or the filter 20 on the air inlet duct 40 with the other hand. This kind of mode is convenient for the user application of force, guarantees the simple operation nature.

Moreover, the air inlet duct 40 is closer to the filter 20 than the holding portion 70, that is, the filter 20 is close to the air inlet duct 40, and generally the main body outlet S2 can be close to the holding portion 70, while the filter 20 is far from the main body outlet S2, since the air inlet duct 40 is an inlet for sucking the air flow, and the filter 20 is close to the air inlet duct 40, the filter 20 filters the air flow earlier, and the air flow carrying more dust flows in the main body 10 in a longer path, so that the dust adhesion in the main body 10 is avoided.

In some embodiments, the grip portion 70 may define a cavity 71, and the cavity of the grip portion 70 may be used to house electronic components, such as a battery, to make full use of the space of the host computer 10. The airflow generating device 30 is partially located above the dust bin 60 and partially located above the cavity. Therefore, the airflow generated by the airflow generating device 30 can pass through the cavity 71 and the dust barrel 60 in the holding part 70, and further the flow path of the airflow is prolonged, and particularly, when the airflow passes through the cavity 71 of the holding part 70, components in the cavity 71 of the holding part 70 can be cooled, and the cooling effect of the whole machine is better under the condition of ensuring reasonable structural layout of the whole machine. As shown in fig. 3, the longitudinal length of the filter 20 is gradually reduced in the loading direction of the filter 20 into the main unit 10. In one embodiment, the longitudinal section of the filter 20 may be trapezoidal, and the length of the portion of the filter 20 near the inside of the main body 10 is smaller than the length of the portion of the filter 20 near the outside of the main body 10. By such design, the small-size end of the filter 20 can enter the host 10 more easily during the process of installing the filter 20 into the host 10, and the filter 20 and the host 10 can be fitted more and more tightly along with the installation of the filter 20 due to the continuous increase of the longitudinal size of the filter 20, so that the filter 20 and the host 10 can be fitted tightly while the installation of the filter 20 into the host 10 is facilitated.

As shown in fig. 3 and 4, a filter accommodating chamber 11 is provided in the main body 10, and a longitudinal sectional shape of the filter accommodating chamber 11 may match a longitudinal sectional shape of the filter 20. As shown in fig. 3, the longitudinal section of the filter 20 may be trapezoidal, and the longitudinal section of the filter accommodating chamber 11 may also be trapezoidal, and the side wall of the filter accommodating chamber 11 may be substantially in close contact with the end and the side of the filter 20, respectively, so as to stably maintain the filter 20 at the preset installation position of the filter accommodating chamber 13.

As shown in fig. 3 and 4, the filter accommodating chamber 11 may include at least two chamber walls disposed opposite to each other, the chamber walls having through holes 131, as shown in fig. 3, the main unit 10 includes an air inlet chamber 12, and the air inlet 21 is communicated with the air inlet chamber 12 through the through holes 131. The air flow passing through the dust-air separating device 50 enters the air inlet chamber 12, passes through the through holes 131, enters the air inlet 21 of the filter 20, and further enters the filter chamber 23 of the filter 20.

A seal 24 can be provided between the filter 20 and the wall of the filter receiving chamber 11, the seal 24 surrounding at least the through-hole 131. Specifically, the sealing member 24 may be a second sealing ring, and the sealing member 24 may be provided at both ends of the filter 20, integrated with the filter 20, and may be installed in the filter accommodating chamber 11 together with the filter 20. In some alternative embodiments, the seal 24 may be provided on the wall of the filter receiving chamber 11.
