Detailed Description
The present invention will be described in detail below with reference to specific embodiments shown in the drawings. These embodiments are not intended to limit the invention and structural, methodological, or functional modifications of these embodiments that may be made by one of ordinary skill in the art are included within the scope of the invention.
The words expressing position and direction in the invention are all that the end near the dust collection mouth of the dust collector is near end and the end near the air outlet of the dust collector is far end, taking the air path of the whole dust collector as reference.
The present invention will be specifically described with reference to a preferred embodiment of an upright cleaner. Referring to fig. 1, the cleaner includes a base 100 and an upright main body 200 having a lower portion coupled to the base 100. The bottom of the base 100 is provided with rollers 110 for movement over the surface to be cleaned. Referring to fig. 2, the bottom of the base 100 is further provided with a downward suction opening, which is in gas communication with the dust cup 220 located at the main body 200 through the first air inlet pipe 210 wound around the rear of the base 100, and collects dust and debris of the surface to be cleaned through the vacuum negative pressure generated by the motor assembly 130. The base 100 is provided with a floor brush assembly 120 around the suction opening to assist in suction, and dust is swept into the suction opening by driving the floor brush to rotate.
The motor assembly 130 is provided to the base 100. Referring to fig. 3, the motor assembly 130 includes a hood 133, a motor 131 installed in the hood 133, an air intake hole 135 and an air exhaust hole provided on the hood 133. The air intake hole 135 is located at one side of the motor 131. The motor 131 is disposed transversely to the base 100, i.e. the motor shaft 139 is parallel to the horizontal plane. A motor air inlet 137 is located within the housing 133 on the center axis of the motor 131, coaxial with the motor shaft 139.
The main body 200 is connected to the base 100 by a rotational joint, and the main body 200 can pivot with respect to the base by the rotational joint. An operating handle 230 is provided above the main body 200. A dust cup 220 is detachably coupled to the main body 200 at a position adjacent to the motor assembly 130, and the dust cup 220 communicates with the floor brush assembly 120 through the first air inlet duct 210. When the dust collector is operated, the dust sucked by the floor brush assembly 120 is collected into the dust cup 220 under the negative pressure of the motor 131, and the dust cup 220 can be detached from the main body 200 when the dust in the dust cup 220 needs to be cleaned. The dirt cup 220 is connected to the motor assembly 130 by a second air inlet conduit 240.
Referring to fig. 1 and 2, the second air inlet pipe 240 has a proximal end connected to the dust cup 220 and a distal end connected to the motor assembly 130, and sucks the filtered air from the dust cup 220 into the motor air inlet 137 by the negative pressure generated by the motor 131. Specifically, referring to fig. 3, a hose housing 241 is disposed at a distal end of the second air inlet pipe 240, and is matched with the air inlet hole 135 of the hood 133, and can be inserted and fixed at the air inlet hole 135. As shown in fig. 4 and 5, the port 243 at the distal end of the second air inlet pipe 240 is opened along the direction indicated by the arrow, the port 243 is disposed on the hose case 241, the port 243 outputs air along the direction indicated by the arrow, and an included angle exists between the port 243 and the air inlet direction of the motor air inlet 137.
In order to smoothly flow into the motor air inlet 137 after the air flows out of the port 243, no chaotic vortex is formed to lose kinetic energy, and a guide cover 140 is arranged between the port 243 and the motor air inlet 137. Referring to fig. 3-5, the pod 140 has an extension 141, an end wall 143, and a connection 145, wherein the proximal end of the extension 141 is shaped to mate with the hose shell 241 and may be received in the port 243, and the distal end of the extension 141 is connected to the end wall 143. The outer surface of the end wall 143 is provided with a connecting portion 145 for fixing the pod 140 within the housing 133.
The extension portion 141 is a semi-open structure, and the main body 200 is semi-surrounded by a side wall to form a semi-circular table shape, and has a circular arc inner section, and the central axis of the circular table extends along the first direction to guide the air flow along the input direction. Because of the high negative pressure near the motor air inlet 137, the air is necessarily gathered towards the motor air inlet 137, the semi-open structure can not cause escape of the kinetic energy of the air, the working efficiency of the dust collector is improved, the cost is saved, and the air guide sleeve 140 is convenient to fix.
The end wall 143 extends substantially in the second direction, directing the air flow in the second direction, with a curved, continuous smooth transition between the extension 141 and the end wall 143. By "extending generally in the second direction" it is meant that the end wall 143 is a curved wall that extends in the second direction in a gas passage formed by the semi-enclosed configuration. The second direction is parallel to the extending direction of the motor shaft 139.
Preferably, the first direction forms an angle of 90 degrees with the second direction.
The extension 141 is provided with an air outlet end 147 adjacent the end wall 143 which cooperates with the motor air inlet 137 and which is arranged to provide a positive flow of air in the second direction into the motor 131 without excessive travel. Referring to fig. 3 and 6, at the air outlet end 147, the lower edge of the end wall 143 and the lower edge of the side wall of the extension 141 extend away from the center of the motor air inlet 137 to form a hat-like ring structure 149 for covering the surface around the motor air inlet 137.
The extension 141 increases in cross-sectional area from the proximal end to the distal end, allowing sufficient space for the airflow to deflect in the distal end.
Preferably, at least one external tangent plane of the end wall 143 is perpendicular to at least one external tangent plane of the side wall of the extension 141, such that the air flows through the pod 140 and then directly into the fan inlet.
The connecting portion 145 is a plurality of clamping ribs connected to the outer surface of the end wall, and is used for being matched with corresponding clamping structures of the hood 133 to fix the air guide sleeve 140.
According to the invention, the air guide sleeve is arranged in the hood, so that gas is smoothly guided from the port of the motor air inlet pipe to the motor air inlet, thereby avoiding the formation of chaotic vortex, reducing the loss of suction power at the hood, reducing the loss of the suction power of the whole cleaner and improving the working efficiency.
It should be understood that although the present disclosure describes embodiments, not every embodiment is provided with a separate embodiment, and that this description is for clarity only, and that the skilled artisan should recognize that the embodiments may be combined as appropriate to form other embodiments that will be understood by those skilled in the art.
The above list of detailed descriptions is only specific to practical embodiments of the present invention, and they are not intended to limit the scope of the present invention, and all equivalent embodiments or modifications that do not depart from the spirit of the present invention should be included in the scope of the present invention.
