Next, referring to fig. 1 to 3, a dust collection base station 100 according to an embodiment of the present invention is described.

As shown in fig. 1, the dust collecting base station 100 according to the embodiment of the present invention is used for collecting dust from a host 200.

According to the utility model discloses collection dirt basic station 100 includes: a shell 10 and a dust collecting part.

Specifically, the peripheral wall of the housing 10 is provided with a dust inlet 111, and a dust collecting channel 113 communicated with the dust inlet 111 is formed in the housing 10, the dust collecting channel 113 is respectively communicated with the dust inlet 111 and the dust collecting port 112, the dust collecting member is communicated with the dust collecting port 112 to collect the garbage, in the flow direction from the dust inlet 111 to the dust collecting port 112, the dust collecting channel 113 comprises a first channel 1131 and a second channel 1132 which are communicated, the first channel 1131 and the second channel 1132 are respectively formed into arc sections, the cross-sectional area of the first channel 1131 is gradually reduced in the direction towards the second channel 1132, and the cross-sectional area of the second channel 1132 is gradually reduced in the direction towards the dust collecting port 112.

It can be understood that the dust inlet 111 is disposed on the outer peripheral wall of the housing 10, the dust inlet 111 is open towards the outer side of the housing 10, the dust collecting channel 113 is located in the housing 10, and one end of the dust collecting channel 113 is communicated with the dust inlet 111, so that the garbage outside the housing 10 can enter the dust collecting channel 113 through the dust inlet 111, the dust collecting port 112 and the dust collecting piece are both located in the housing 10, the other end of the dust collecting channel 113 is communicated with the dust collecting port 112, and the dust collecting port 112 is communicated with the dust collecting piece, that is, the dust collecting channel 113 is communicated between the dust inlet 111 and the dust collecting port 112.

Therefore, the garbage outside the housing 10 can enter the dust collecting member through the dust inlet 111, the dust collecting channel 113 and the dust collecting port 112 in sequence, and a fan (not shown in the figure) is arranged on one side of the bottom of the dust collecting member, and the fan is used for generating an air flow in the dust collecting channel 113 during operation, the air flow is suitable for flowing along the direction from the dust inlet 111 to the dust collecting port 112, the flowing direction is shown by a dotted line (with an arrow) in fig. 2, in other words, the fan can generate a suction force on the garbage at the dust inlet 111 by generating the air flow in the flowing direction, so that the garbage at the dust inlet 111 can rapidly enter the dust collecting member under the driving of the air flow.

Further, as shown in fig. 2, in the flow direction from the dust inlet 111 to the dust collecting port 112, the dust collecting channel 113 includes a first channel 1131 and a second channel 1132 which are communicated with each other, the first channel 1131 and the second channel 1132 are respectively formed into arc-shaped segments, and the arc degree of the first channel 1131 is different from the arc degree of the second channel 1132, for example, the arc degree of the first channel 1131 is greater than the arc degree of the second channel 1132, and of course, the arc degree of the first channel 1131 may be smaller than the arc degree of the second channel 1132, which is not limited herein.

Therefore, when the airflow drives the garbage to pass through the first channel 1131 and the second channel 1132, the garbage can have different centrifugal force and acceleration, so that the garbage can rapidly enter the dust collecting part.

Wherein the cross-sectional area of the first passage 1131 gradually decreases in a direction toward the second passage 1132, and the cross-sectional area of the second passage 1132 gradually decreases in a direction toward the dust collection port 112. In other words, in the flow direction from the dust inlet 111 to the dust collection port 112, the first passage 1131 and the second passage 1132 are sequentially communicated, and the inner diameter of the first passage 1131 gradually decreases in the direction toward the second passage 1132, and the inner diameter of the second passage 1132 gradually decreases in the direction toward the dust collection port 112, that is, the inner diameter of the dust collection passage 113 in the flow direction from the dust inlet 111 to the dust collection port 112 gradually decreases.

Therefore, when the airflow drives the garbage to enter the dust collecting part along the extending direction of the dust collecting channel 113, because the cross sectional areas of the dust collecting channel 113 are different in the flowing direction from the dust inlet 111 to the dust collecting port 112, that is, the inner diameters of the dust collecting channel 113 are different, the garbage with different particle sizes or different qualities has different centrifugal forces and accelerations at the same position, so that the garbage with different particle sizes or different qualities enters the dust collecting part at different speeds, that is, the sequence of the garbage with different particle sizes or different qualities entering the dust collecting part is different, and the garbage with different particle sizes or different qualities can enter the dust collecting part orderly, thereby avoiding the problem of blockage of the garbage in the dust collecting channel 113, and being beneficial to improving the dust collecting efficiency of the dust collecting base station 100.

Wherein, the cross-sectional area of the one end that first passageway 1131 and dust inlet 111 communicate is greater than the cross-sectional area of the one end that second passageway 1132 and collection dirt mouth 112 communicate, and the cross-sectional area of the one end that first passageway 1131 and dust inlet 111 communicate is great promptly, and is corresponding, will enter the size design of dust inlet 111 great, compares in the less design of dust inlet among the prior art, the utility model discloses on the basis of the full combination of daily rubbish (such as melon seed shell, peanut shell) equidimension size, increased the size of dust inlet 111 to avoid appearing rubbish card and appearing card shell scheduling problem at dust inlet 111, in order to prevent rubbish from appearing the problem of jam in dust inlet 111 department, and be convenient for reduce the windage of air current in dust inlet 111 department, so that the air current can drive rubbish and get into in first passageway 1131 smoothly, and guarantee that rubbish can get into second passageway 1132 smoothly.

According to the utility model discloses collection dirt basic station 100, its first passageway 1131 and second passageway 1132 form the segmental arc respectively, and in the flow direction of entering dirt mouth 111 to dust collection mouth 112, the cross sectional area of first passageway 1131 and the cross sectional area of second passageway 1132 all reduce gradually, thereby make the cross sectional area of first passageway 1131 and the one end that advances dirt mouth 111 and link to each other great, in order to avoid rubbish to appear the problem of jam in dust inlet 111 department, and be convenient for reduce the windage of air current in dust inlet 111 department, so that the air current can drive rubbish and get into collection dirt passageway 113 smoothly, and simultaneously, be convenient for different masses, rubbish of different particle sizes can get into the piece of gathering dust through first passageway 1131 and second passageway 1132 in an orderly manner, in order to solve rubbish and appear the problem of jam in collection dirt passageway 113, do benefit to improve collection dirt basic station 100's collection efficiency.

In some embodiments, the dust collection port 112 is tangentially disposed on an end arc of the second passage 1132.

It will be appreciated that the dust collection port 112 is tangential to the end of the second passage 1132 facing away from the first passage 1131 and communicates with the dust collection member.

Therefore, when the airflow drives the garbage to enter the dust collecting part from the second channel 1132 through the dust collecting opening 112, the garbage can be buffered and decelerated to a certain extent due to the centrifugal force of the garbage when passing through the dust collecting opening 112, so that the garbage is prevented from being too large in speed.

Further, as shown in fig. 2, the cross-section of the dust collection passage 113 includes two parallel extension lines each extending from the dust inlet 111 toward the dust collection port 112, each extension line being an involute curve.

In other words, the dust collection passage 113 is configured as an involute passage, i.e., both the first passage 1131 and the second passage 1132 are configured as involute passages, or at least the second passage 1132 is configured as an involute passage.

Preferably, the first channel 1131 and the second channel 1132 are both configured as involute channels, so that when the airflow drives the garbage to enter the dust collecting part along the extending direction of the dust collecting channel 113, the garbage with different particle sizes or different qualities has different centrifugal forces and accelerations at the same position, so that the garbage with different particle sizes or different qualities enters the dust collecting part at different speeds, that is, the sequence of the garbage with different particle sizes or different qualities entering the dust collecting part is different, and further the garbage with different particle sizes or different qualities can enter the dust collecting part orderly, thereby avoiding the problem of blockage of the garbage in the dust collecting channel 113, and facilitating improvement of the dust collecting efficiency of the dust collecting base station 100.

In some embodiments, as shown in fig. 3, a center O of a base circle O1 of the involute L is defined as an origin of a coordinate system, a position of an arbitrary point M of the involute L in the coordinate system is defined as (X, Y, Z), a radius of the base circle O1 is defined as r, an intersection point of the base circle O1 and an X axis of the coordinate system is defined as an a point, an arbitrary point on the base circle O1 is defined as a B point, and a forward projection point of the B point on the X axis is defined as a C point, and the arbitrary point M satisfies the following relation:

X＝r*cosθ+S*sinθ；

Y＝r*sinθ-S*cosθ；

Z＝0；

where θ is @ MBC and S is the arc length of the portion of the base circle between points A and B.

The specific calculation process is as follows:

for example: the base circle is O1, the center of the circle is O, the radius of the base circle is r, the involute is L, any point on the base circle O1 is a point B, the orthographic projection point of the point B on the X axis is a point C, and the position of any point M of the involute L in a coordinate system is defined as (X, Y, Z).

Wherein, let ≈ XOB = theta, OB = r, arc length = S of the part between point A and point B, make perpendicular BC, ME of OX through point B, M separately, BC, ME intersect with X axle at point C, E separately; the perpendicular to BC is made through point M, which intersects BC at point D.

From the definition of the involute, the following equation can be obtained:

AB = BM = AM (arc length of the portion of the involute L between point a and point M) = S =2r pi/360 θ, where pi is the circumferential ratio;

since BC is parallel to OY so that ═ YOB = ═ OBC, DM = CE, and since MB is perpendicular to OB (definition of the involute), so ═ MBO = = = = = = = = ═ YOX = = ═ YOB ═ XOB = θ, we can obtain:

OE＝OC+CE＝OC+DM＝OB*coSθ+BM*sinθ＝r*cosθ+S*sinθ

EM＝CD＝CB-BD＝OB*sinθ-BM*cosθ＝r*sinθ-S*cosθ

the following relationships are obtained:

X＝r*cosθ+S*sinθ；

Y＝r*sinθ-S*cosθ；

Z＝0。

therefore, the coordinate of any point M on the involute L in the coordinate system can be conveniently obtained.

In some embodiments, the involute employs a cartesian coordinate system:

the equation: r =1;

ang＝360*t；

S＝2*pi*r*t；

X0＝s*cos(ang)；

Y0＝s*sin(ang)；

x＝XO+s*sin(ang)；

y＝y0-s*cos(ang)；

z＝0；

wherein pi is the circumference ratio, t is the period, i.e. t is the number of turns of the base circle, and S is the arc length of the base circle rotated by t turns.

In some embodiments, the dust collection base station 100 further comprises a guide duct (not shown).

The guide air duct is located between the dust collection port 112 and the dust collection member, and the guide air duct is respectively communicated with the dust collection passage 113 and the dust collection member. That is to say, the guide air duct is communicated between the dust collecting opening 112 and the dust collecting part, so that under the action of the fan, the air flow can drive the garbage at the dust collecting opening 112 to enter the dust collecting part through the guide air duct, so that the guiding effect on the garbage through the guide air duct is facilitated, and the garbage can smoothly enter the dust collecting part.

Furthermore, the guide air duct extends vertically, that is, the lower end of the guide air duct is communicated with the dust collecting port 112, and the upper end of the guide air duct is communicated with the dust collecting part, that is, under the action of the fan, the airflow can drive the garbage at the dust collecting port 112 to enter the dust collecting part along the vertical direction.

Therefore, the gravity of the garbage with different qualities is different, or the resistance of the garbage with different particle sizes is different, so that the movement speed of the garbage with different qualities or the garbage with different particle sizes in the guide air channel is different, therefore, the garbage with different qualities or the garbage with different particle sizes can orderly enter the dust collection part, the blockage of the inlet of the dust collection part is avoided, and the improvement of the dust collection efficiency is facilitated.
