In some embodiments, the dust-gas separation device 910 further includes a main body 914 connected to the blocking portion 911, where the main body 914 and the blocking portion 911 form a receiving space, and the inhaled objects first enter the receiving space through the mounting opening 912, and at least a portion of the inhaled objects is blocked by the blocking portion 911. To prevent the collection device 750 from being broken, the main body 914 is formed with a plurality of air holes 913 through which air can flow.

In one embodiment, the main body 914 is a cover-shaped structure with an opening at the bottom, and the main body 914 includes a top plate and a side portion protruding downward around the circumference of the top plate, where the side portion may be a solid plate, and the solid plate is provided with air holes 913, or the side plate may be a wire mesh structure, and the mesh is the air holes 913. By providing the air holes 913 in the side of the main body 914, the fallen leaves can easily enter the collecting device 750, and the air sucked into the suction duct 711 together with the fallen leaves can flow out of the air holes 913.

In some particular embodiments, the main body 914 of the dust gas separation apparatus 910 is substantially cubic; in some side-by-side embodiments, the main body 914 of the dust gas separation apparatus 910 is generally cylindrical. The shape of the main body 914 is not limited.

The dust-gas separation apparatus 910 includes a mounting port 912, and the air blowing port 102 is inserted into the mounting port 912.

Of course, in some other embodiments, the mounting port 912 and the air blowing port 102 may be configured in other shapes, such as T-shaped, pi-shaped, etc., as desired.

With continued reference to FIG. 1, in some embodiments, the suction barrel 711 is a smooth-walled hose that is easy to house. In some specific embodiments, the suction cylinder 711 has a bellows structure, and specifically includes a spiral supporting strip for supporting and a soft ventilation material covered on the spiral supporting strip, where the soft ventilation material may be cotton cloth or plastic cloth. The soft ventilation material can not only block objects such as fallen leaves in the air suction cylinder 711, but also play a role in ventilation. The suction cylinder 711, which is a hose structure, may be used for various kinds of air flow devices that can blow or suck air, such as a hand-held blower, a backpack blower, a cleaner, etc.

Of course, in other embodiments, the hose may be provided as a fixed wide suction inlet, due to different usage habits of the user, and also to reduce suction loss due to hose resistance. The fallen leaves are swept together by the harrow, and the fallen leaves are sucked by the black suction port. Because the air suction port is of a fixed shape, but not of a flexible structure which is easy to deform, the air quantity loss caused by radian, fluctuation and the like of the inner wall of the corrugated pipe is reduced, and because the inner wall is uneven, the air can lose some energy to overcome the resistance of the inner wall.

With continued reference to fig. 1, 2 and 5, the airflow apparatus further includes a support frame 920, where the support frame 920 is configured to support the collection device 750. Thus, the user does not have to hold the collection device 750, and can free up a certain amount of labor.

In some embodiments, the support frame 920 includes a support sleeve 921 and a plurality of support rods 922, the support sleeve 921 is sleeved and fixed at the collecting port of the collecting device 750, the plurality of support rods 922 are arranged along the circumferential direction of the support sleeve 921 at intervals, and the top end of each support rod 922 is connected with the support sleeve 921.

In some specific embodiments, the support rods 922 are inclined from top to bottom outwards, so that the cross-sectional area of the space formed by surrounding the support rods 922 is gradually increased from top to bottom, and the stability of the support frame 920 on the collecting device 750 is improved.

In one embodiment, a connecting rod 923 is further disposed between two adjacent support rods 922, and the connecting rod 923 is horizontally disposed and is used to strengthen the structural stability of the support frame 920, so as to further improve the support stability of the support frame 920 to the collecting device 750.

In one embodiment, the support frame 920 may be supported directly on the airflow apparatus such that the airflow apparatus (e.g., a blower) may "stand" autonomously when operating in the suction mode, without requiring the user to hold the apparatus with his or her hand. For a suction defoliator, the suction fan has no blowing function, and the support 920 may be integrally provided with the suction defoliator, i.e., the support 920 is non-detachably connected with the suction defoliator. For a blower, the blower has a blowing mode and a suction mode, and the support 920 may be configured to be detachably coupled to the blower. When the blower is used in the blowing mode, the user can hold the blower with his hand. When the blower is operated in the suction mode, the user may hold the blower in his/her hand or may use the support frame 920 to support the blower. The manner of being supported by the support frame 920 or the hand-held manner depends on the service condition of the blowing and sucking machine.

In a specific embodiment, the support sleeve 921 is a square ring sleeve, the number of support bars 922 is four, and the number of connecting bars 923 is also four.

In some embodiments, the dust gas separation device 910 is removably coupled within the support sleeve 921. The detachable connection mode comprises plugging, buckling connection, magnetic attraction and the like.

It should be noted that the air flow device may be directly placed and fixed on the supporting frame 920, and the air flow device may be used as a relatively fixed device. Of course, when the airflow device is not supported by the support frame 920, the airflow device can still be used as a traditional handheld airflow device.

With continued reference to fig. 1, to facilitate the handling of the airflow apparatus by a user, the airflow apparatus further includes a primary handle 610 and a secondary handle 640, wherein the primary handle 610 is connected above the housing 100 and the secondary handle 640 is connected behind the housing 100. The user can easily operate the air flow device by holding the main handle 610 with one hand and holding the sub-handle 640 with the other hand.

With continued reference to fig. 1, the airflow apparatus further includes a battery pack 800, and a plug structure is disposed at the rear of the housing 100, where the battery pack 800 is detachably plugged. In some embodiments, the plugging direction of the battery pack 800 forms an angle with the vertical direction, so that the user can easily disassemble and assemble the battery pack 800.

It should be noted that, the technical solutions described throughout the present application may be applied to different air flow devices such as a hand-held blower, a backpack blower, or a blower with a blowing mode, and when the present application refers to "air flow device", it is not limited to what type of air flow device, and any device that performs work through the flow of air flow may be referred to as "air flow device". The term "blower" as used herein is not limited to the blower mode of a hand-held blower, a backpack blower, or a blower, and thus when referring to "blower" it is understood that various types of blowers are used in general terms unless the text specifically defines a particular type of blower.

The foregoing has outlined and described the basic principles, main features and advantages of the present application. It will be appreciated by persons skilled in the art that the above embodiments are not intended to limit the present application in any way, and that all technical solutions obtained by means of equivalent substitutions or equivalent transformations fall within the scope of the present application.
