As shown in fig. 1 to 4, a handheld vacuum cleaner provided by the present application is used for treating a surface to be cleaned, especially cleaning a desk top, fig. 1 is a schematic structural view of the handheld vacuum cleaner provided by the present application in one embodiment, fig. 2 is an exploded schematic view of fig. 1 in a bottom view, fig. 3 is an exploded schematic view of fig. 1 in a top view, and fig. 4 is a schematic sectional structural view of fig. 1. In this application, the hand-held cleaner comprises: an upper cover 110 having an air outlet 111 formed on an outer circumferential surface thereof; a lower cover 120 detachably coupled to the upper cover 110; the lower cover 120 is fastened with the upper cover 110 to form an accommodating space; wherein, the bottom end surface of the lower cover 120 is formed with an air inlet hole 121, and the air inlet hole 121 is communicated with the air outlet hole 111 through the accommodating space; a base 160 disposed in the accommodating space; the suction assembly 130 is arranged on the base 160 and is used for forming negative pressure on the air inlet holes 121 to suck dirt on the surface to be cleaned, so that dirty air containing the dirt can flow into the accommodating space from the air inlet holes 121; a filter assembly 140 disposed in the accommodating space and closer to the lower cover 120 than the suction assembly 130 for filtering the dirty air; the suction assembly 130 is further configured to form a positive pressure at the air outlet 111, so that the filtered clean air can flow out of the accommodating space through the air outlet 111; the control assembly 150 is electrically connected with the suction assembly 130 and used for controlling the opening and closing of the suction assembly 130; and at least one scraping member 170 disposed on the bottom surface of the lower cover 120 and surrounding the air inlet hole 121.
That is, in the present application, the cover body is a split type design, including the upper cover 110 and the lower cover 120. Of course, in other embodiments, the cover may be integrally formed.
Through the mode, the air flow channel from bottom to top is formed between the air inlet 121 and the air outlet 111, and the base 160, the suction assembly 130 and the filter assembly 140 are respectively installed in the accommodating space along the direction from the lower cover 120 to the upper cover 110, so that the air conditioner has the advantages of simple structure and convenience in assembly and disassembly.
In operation, the scraping member 170 can maintain a certain gap between the air inlet 1211 of the lower cover 120 and the surface to be cleaned, so that a certain micro-vacuum effect is formed around the air inlet 1211 to suck the dirt on the surface to be cleaned. In order to further enhance the vacuum effect at the air inlet 1211, the bottom end surface of the lower cap 120 is formed with an outer protrusion 180 that is circumferentially provided to the air inlet 1211 along the circumferential direction of the air inlet hole 121, and the plurality of scraping members 170 are positioned at the outer circumference of the outer protrusion 180. Wherein the outer protrusions 180 are configured as bottom extensions of the air inlet holes 121 for shortening a gap value Z between the bottoms of the air inlet holes 121 and a surface to be cleaned to further increase a vacuum degree at the air inlet holes 121. In the present application, the external protrusion 180 is considered as a part of the air inlet hole 121, and referring to fig. 4, in the case where the external protrusion 180 is not provided, the gap value between the bottom of the air inlet hole 121 and the surface to be cleaned is Z'; after the outer convex part 180 is arranged, the gap value between the bottom of the air inlet hole 121 and the surface to be cleaned is Z, the bottom of the air inlet hole 121 is the outer convex part 180, the gap value Z is the gap between the outer convex part 180 and the surface to be cleaned in the up-down direction, and Z is less than Z', so that the suction force at the air inlet 1211 can be improved, dirt on the table top can be sucked more efficiently, and the cleaning effect is good.
Specifically, the air inlet 1211 of the air inlet hole 121 is formed in a shape of a flared opening with a large lower portion and a small upper portion, and the aperture of the air inlet 1211 gradually decreases in a direction from the lower cover 120 to the upper cover 110, so as to reduce the pressure of the air flow entering the air inlet hole 121. The outward protrusion 180 is disposed around the connection area between the flared air inlet 1211 and the bottom surface of the bottom cover 120, and is coaxial with the air inlet hole 121.
The arrangement of the external protrusion 180 is various, and in order to simplify the structure of the external protrusion 180, so that the external protrusion 180 is mounted on the bottom end surface of the lower cap 120, the external protrusion 180 is provided with a ring-shaped rib. Considering that the convex portion 180 is disposed at the air inlet 1211, the air flow can enter the air inlet hole 121 after passing through the convex portion 180, and the convex portion 180 is provided with a flow guide surface for guiding the air flow, so as to reduce the wind resistance. The section of the diversion surface in the radial direction of the air inlet hole 121 is an arc line or an arc line chain formed by smoothly connecting multiple arc lines, so that the wind resistance can be effectively reduced, and the air flow can enter the air inlet hole 121 conveniently. It is understood that the shape of the flow guiding surface on the convex portion 180 is not limited thereto, and may also be a combination of an arc line and a straight line, and is not further limited herein.
In order to prevent the dust accumulated in the lower cover 120 from flying from the air inlet holes 121 to the external surface to be cleaned, a dust pressing structure is provided at the air outlet 1212 of the air inlet holes 121. The air inlet 1211 of the air inlet opening 121 is disposed opposite to the air outlet 1212, and the air outlet 1212 is located right above the air inlet 1211 and faces the filter assembly 140. Referring to fig. 3, the lower cover 120 is hollow and has an open top to form a dust collecting chamber 122 for depositing dust, and the top and bottom directions are the same as the "top" and "bottom" directions in the drawing. The air inlet holes 121 are formed at the center of the dust chamber 122, and dirty air is introduced into the dust chamber 122 through the air inlet holes 121. In the present application, the outlet 1212 has a flared shape with a small lower portion and a large upper portion, and the inner diameter and the outer diameter of the outlet 1212 gradually increase in a direction from the inlet 1211 to the outlet 1212, so as to form the dust-pressing structure. The dust pressing structure can expand at the air outlet 1212 and reduce the air speed of the air outlet 1212, so that dust in the dust collecting cavity 122 is prevented from being rolled up by the airflow and flying.
When a table top or other table surfaces are cleaned, air flow blown out from an air outlet of the handheld dust collector in the prior art is difficult to avoid acting on articles placed on the table top or the table surfaces, and if the articles are light in weight, the documents are easily blown out by the air flow, so that unnecessary troubles are caused. In view of this, the air outlet 111 in the present application can blow air at an obliquely upward angle, thereby reducing the risk that the blown air will blow away the document on the surface to be cleaned. Specifically, the air inlet 121 has a first central axis L, the air outlet 111 has a second central axis H, and a preset included angle M exists between the first central axis L and the second central axis H, so that the air outlet 111 can output air at an oblique upward angle.
Considering that the air outlet effect of the air outlet 111 is affected by too large or too small inclination angle, the range of the preset angle M is set between 15 ° and 75 °, preferably, the values of the preset angle M are 30 °, 45 °, and 60 °, under the above values, the wind resistance is small, and the air outlet effect of the air outlet 111 is good.
Further, a plurality of air outlets 111 are disposed on the outer peripheral surface of the upper cover 110 and/or the lower cover 120 in a predetermined order, and the outer peripheral surface in this application refers to an outer sidewall. The air outlet holes 111 are arranged on the outer peripheral surface of the upper cover 110 and/or the lower cover 120 according to a preset sequence, and the air outlet holes 111 are arranged on the outer peripheral surface of the upper cover 110 according to the preset sequence, and the air outlet holes 111 are arranged on the outer peripheral surface of the lower cover 120 according to the preset sequence, and the air outlet holes 111 are arranged on the outer peripheral surfaces of the upper cover 110 and the lower cover 120 according to the preset sequence. The air outlets 111 may be distributed in an array, selectively distributed, or spirally distributed. It can be understood that the aperture arrangement of the air outlet 111 has various forms, specifically, the apertures of the air outlets 111 gradually increase and then gradually decrease in the extending direction of the first central axis L; the aperture of the plurality of air outlet holes 111 gradually increases and then gradually decreases in the circumferential direction of the upper cover 110 and/or the lower cover 120. It can be understood that the plurality of air outlets 111 are arranged in various manners, and the second central axes H of the plurality of air outlets 111 extend to intersect with the first central axis L; or the second central axes H of the plurality of outlet holes 111 are arranged parallel to each other.
Further, the filter assembly 140 includes a support member 141 and a filter member 142, and the filter member 142 is disposed on the support member 141. Considering that the filter element 142 of the hand-held cleaner accumulates a large amount of dust and dirt after use, it is periodically cleaned to ensure the filtering performance. In view of this, the filter element 142 is detachably disposed on the support element 141, and the support element 141 is provided with a position-limiting structure 144 for blocking the filter element 142. The filter element 142 is used for filtering dirty air, the filter element 142 includes a filter screen 1421 and a filter cartridge 1422, the filter screen 1421 may be a nylon mesh, the filter cartridge 1422 may be a sponge block, and the filter element 142 belongs to the prior art and is not further limited herein.
Specifically, the supporting member 141 is recessed downwards at the middle to form an installation groove 143 for installing the filtering member 142, the installation groove 143 is circumferentially hollowed out to form a filtering opening 145 for the inflow of dirty air, and the limiting structure 144 is disposed at the top edge of the installation groove 143. In a specific application scenario, the limiting structure 144 is a fixture block formed on the top edge of the mounting groove, and the fixture block is used for limiting the filtering element 142 in the axial direction. The bottom of the mounting groove 143 is formed with a shielding portion 1414, the shielding portion 1414 is disposed opposite to the air inlet opening 121, and the shielding portion 1414 at least partially covers the air inlet opening 121 along the direction from the air inlet 1211 to the air outlet 1212. When a user's finger or a foreign object accidentally extends into the air inlet opening 121 along the axial direction of the air inlet opening 121, the finger or the foreign object cannot further extend inward under the blocking of the blocking portion 1414, so as to avoid contacting with the suction assembly 130 inside the handheld vacuum cleaner, which has the advantage of safe and reliable use.
In consideration of the shielding effect of the shielding portion 1414, the shielding portion 1414 is provided to completely cover the air inlet holes 121 in the axial direction of the air inlet holes 121, and specifically, the shielding portion 1414 is substantially disk-shaped and is provided coaxially with the air inlet holes 121. Therefore, fingers or foreign objects can be effectively prevented from extending into the handheld dust collector.
Considering that the shielding portion 1414 changes the flow direction of the dirty air, the shielding portion 1414 needs to have a function of guiding the airflow. Specifically, the shielding portion 1414 is generally in a gradually downward-slanted warped configuration in a direction extending from the center toward the edge thereof, and guides the dirty air to the filter opening 145. With reference to fig. 4 in combination with fig. 5, fig. 5 is an exploded view of the filter assembly shown in fig. 1, the hollow arrows in fig. 4 represent the flow path of the dirty air, and after the dirty air enters the handheld vacuum cleaner vertically through the air inlet holes 121, the state of the dirty air being sucked vertically is changed by the shielding portion 1414, and the dirty air can move toward the filter opening 145 in a certain curved arc, so that the flow path of the dirty air is effectively extended, the dirty air is prevented from being filtered in a vertical sucking manner, and the dust-air separation of the dirty air is facilitated.
