Background

The atomizing device tears the liquid into fog drops with tiny diameters based on the centrifugal motion of the atomizing disc so as to spray crops. The existing atomization device is limited by design, the coaxially arranged atomizing disc, the atomization disc, the liquid inlet disc and the driving device are designed to be in interference fit, and the atomization device is fixed mutually in a hammering or knocking mode during assembly. The assembly mode has potential safety hazard during fixing, the assembly yield is not high, and the atomization device assembled by the mode can not be disassembled after being completely assembled. The service life of an atomizing device assembled by using a violent method can be greatly shortened. Due to the wear over time, when the parts of the inner parts of the atomizing device need to be replaced, corresponding tools are needed, so that the implementation process is particularly complicated. Therefore, the atomizing device can only be directly replaced, which results in cost increase and affects user experience.

In addition, because of the design limitation of the atomizing disk in the prior art, the teeth of the flow channel arranged on the atomizing disk are high in density and continuous, so that a narrow flow channel is formed. At higher flow rates (e.g., 5L/min of liquid exiting at the inlet), the narrower flow path is likely to cause liquid blockage. Meanwhile, the liquid for agriculture often contains impurities such as flocculent aquatic weeds and the like, the impurities flow into the flow channel along with the liquid, and the blockage of the flow channel is a necessary result under the double effects of the narrow flow channel and the impurities. The blockage of the flow channel not only influences the final atomization effect of the atomization device, thereby causing the problems of uneven liquid flow speed and uneven fog drops. When the liquid is blocked in the flow passage, too much liquid tends to spread axially because the liquid does not flow out, and the whole atomization device is difficult to be waterproof. In addition, the uncertainty of the substances in the liquid can easily cause the atomization device to be corroded, thereby greatly reducing the service life of the whole atomization device.

Fig. 1 to 9 show a centrifugal atomizing device 1000 according to an embodiment of the present invention. The centrifugal atomization device 1000 can be mounted below or to the side of the moving assembly. The moving assembly can be aerial operation equipment for performing spraying operation, or ground operation equipment, or water surface operation equipment and the like. The centrifugal atomization device 1000 includes the main tray 14 and the auxiliary tray 16, or only includes the main tray 14 for performing centrifugal atomization on liquid. Meanwhile, the centrifugal atomization device 1000 may be used in a vertical posture, or may be used in an inclined or horizontal posture.

Referring to fig. 1, the centrifugal atomization device 1000 includes a driving assembly 11, a liquid guiding device 12, a main disc 14, and an auxiliary disc 16, which are coaxially disposed (i.e., sequentially disposed along an assembly axis P). The driving shaft 111 extends from the bottom of the driving assembly 11 and sequentially penetrates through the liquid guiding device 12 and the main tray 14, and the driving shaft 111 extends from the axial center to penetrate through the auxiliary tray 16 by the auxiliary shaft 112. The main disc 14 is driven to rotate about the central axis (i.e., the mounting axis P) by the driving shaft 111 from which the driving assembly 11 extends, and the auxiliary disc 16 is driven to rotate about the central axis (i.e., the mounting axis P) by the auxiliary shaft 112 from which the driving shaft 111 extends; wherein, the main tray 14 and the auxiliary tray 16 rotate in opposite directions or in the same direction. The liquid guiding device 12 is disposed between the driving assembly 11 and the main tray 14 to guide the liquid into the main tray 14. The liquid guiding device 12 delivers liquid to the main tray 14 to atomize the liquid for the first time through the main tray 14, and the main tray 14 delivers the liquid after the first atomization to the auxiliary tray 16 to atomize the liquid after the first atomization for the second time through the auxiliary tray 16, so as to convert the liquid into more tiny droplets to perform spraying operation.

Referring to fig. 1 and 7, the liquid guiding device 12 includes a liquid guiding upper cover 121, a liquid guiding sealing ring 122 and a liquid guiding lower cover 123, which are coaxially arranged in sequence (i.e., arranged in sequence along the assembly axis P). The upper liquid guiding cover 121 and the lower liquid guiding cover 123 enclose to form a hollow cavity D, and the liquid guiding sealing ring 122 is arranged at the joint of the upper liquid guiding cover 121 and the lower liquid guiding cover 123, so as to ensure the sealing effect of the joint of the upper liquid guiding cover 121 and the lower liquid guiding cover 123. Likewise, the catheter seal 122 may be omitted. Preferably, a liquid guiding sealing ring 122 is disposed at the joint of the liquid guiding upper cover 121 and the liquid guiding lower cover 123 to better ensure the sealing effect of the whole liquid guiding device 12 formed by the combination of the liquid guiding upper cover 121, the liquid guiding sealing ring 122 and the liquid guiding lower cover 123. A liquid inlet pipe 1231 communicated with the hollow cavity D is formed at the side of the liquid guiding upper cover 121, and an annular liquid outlet 1232 communicated with the hollow cavity D is formed at the bottom of the liquid guiding upper cover 121 and the liquid guiding lower cover 123 after assembling. The liquid is delivered to the liquid guiding device 12 through the liquid inlet pipe 1231 at the side portion along the flow direction H, and the liquid flows into the hollow cavity D and is delivered to the main tray 14 through the annular liquid outlet 1232 at the bottom portion along the flow direction B (see fig. 5), so that the purpose that the liquid guiding device 12 delivers the liquid to the main tray 14 is achieved.

Referring to fig. 2 and 3, the main tray 14 includes a tray 21 and an annular cover 22 disposed coaxially with the tray 21. The disc body 21 is provided with a plurality of supporting portions 213 protruding from one side facing the annular cover 22, and the annular cover 22 is provided with a fixing portion 221 detachably connected to the supporting portions 213. The supporting portion 213 includes a base 2131 fixed to the tray 21 and a connecting seat 2132 provided on the base 2131. The fixing portion 221 is provided with a second connecting hole 2211 for the connecting seat 2132 to pass through. The fixing portion 221 penetrates the connecting seat 2132 through the second connecting hole 2211, and fixes the annular cover 22 on the tray body 21 through a connecting member (not shown), so as to achieve the detachable connection between the tray body 21 and the annular cover 22. Of course, the connection manner of the disc body 21 and the annular cover 22 may also be any other manner, for example, the disc body 21 and the annular cover 22 are detachably connected through the mutual cooperation of a screw and a nut, which is not limited in this embodiment. As long as the detachable connection of the tray 21 included in the main tray 14 and the ring-shaped cover 22 can be achieved, thereby achieving the purpose of facilitating the quick detachment of the main tray 14 itself. After the disc body 21 and the annular cover 22 are assembled, an annular accommodating cavity a (shown in fig. 5) for uniform flow of liquid is formed between the disc body 21 and the annular cover 22. A liquid inlet (not labeled) for conveying liquid to the annular accommodating cavity a is annularly arranged in the center of the annular cover body 22, that is, the annular cover body 22 is formed by enclosing an inner ring and the driving shaft 111 together. The cross section of the base 2131 is not adapted to the cross section of the connecting seat 2132, and the cross section of the second connecting hole 2211 is only adapted to the cross section of the connecting seat 2132, so as to ensure that the second connecting hole 2211 only penetrates through the connecting seat 2132, and simultaneously ensure that the lower surface ring surface (not shown) of the fixing portion 221 partially or completely abuts against the upper surface ring surface 21311 of the base 2131, so as to form a channel C (see fig. 5) at the edge of the disc 21 and the annular cover 22, for conveying the liquid in the annular accommodating cavity a to the edge of the disc 21. For example, the cross section of the base 2131 is a circle with a radius of R1, the cross section of the second connection hole 2211 is a circle with a radius of R2, the cross section of the connection seat 2132 is a circle with a radius of R3, and R1 > R2 > R3, so as to ensure that the second connection hole 2211 can only be sleeved on the connection seat 2132 and abut against the base 2131, thereby forming a channel C between the tray 21 and the annular cover 22 for conveying the liquid in the annular accommodating cavity a to the edge of the tray 21. Of course, the shape of the cross section may be an irregular shape, such as a triangle, a quadrangle, etc., as long as it is achieved that the second connection hole 2211 can only be sleeved on the connection seat 2132 and abut against the base 2131, so as to form a channel C at the edge of the tray body 21 and the annular cover 22 for conveying the liquid in the annular accommodating cavity a to the edge of the tray body 21.

Referring to fig. 2 to 4, the tray body 21 is provided with a connecting tube 214 and a locking mechanism 13 from the symmetrical center, wherein the connecting tube 214 is sleeved outside the driving shaft 111 and extends into the liquid inlet. The locking mechanism 13 is sleeved outside the connecting cylinder 214 to adjust the axial locking degree of the connecting cylinder 214 and the driving shaft 111, so as to axially separate or fix the main tray 14 from the driving shaft 111, and finally facilitate the detachment of the main tray 14. The connecting tube 214 includes a fixing seat 2142 fixed to the plate 21 and a locking tube 2143 disposed above the fixing seat 2142. The side wall of the locking barrel 2143 defines a plurality of slits 2141. The locking mechanism 13 includes a locking ring 231 sleeved on the connecting cylinder 214 only, so as to adjust the size of the notch 2141 through the locking ring 231, thereby adjusting the axial locking degree of the locking cylinder 2143 and the driving shaft 111, and adjusting the axial locking degree of the main disc 14 and the driving shaft 111, so as to axially separate or fix the main disc 14 and the driving shaft 111. The locking ring 231 may adjust the size of the gap 2141 in a specific manner, wherein a first thread (not shown) is formed on the outer sidewall of the locking barrel 2143, and a second thread (not shown) is formed on the inner sidewall of the locking ring 231. It should be noted that one or both of the two threads need to be threads with an inclined plane end, and the tightening has a shrinking effect similar to the bit grip principle of an electric drill, and the size of the notch 2141 can be adjusted to tightly hold the driving shaft 111 by the mutual matching of the first thread and the second thread. The locking mechanism 13 may further include a fixing boss 2312 having a through hole 2311 and arranged along the circumferential direction of the locking ring 231, and a plurality of screws (not shown) transversely penetrate through the fixing boss 2312 to screw into or screw out of the through hole 2311 so as to achieve the purpose of adjusting the size of the notch 2141, so that the connecting cylinder 214 and the driving shaft 111 are switched between the locking state and the separating state. Of course, in addition to the above-mentioned adjustment of the size of the notch 2141 by the locking ring 231 to adjust the axial locking degree of the locking barrel 2143 with the driving shaft 111, and to adjust the axial locking degree of the main disc 14 with the driving shaft 111 to achieve the axial separation or fixation of the main disc 14 with the driving shaft 111. It is also possible that the cutout 2141 is omitted from the side of the connector barrel 214 and the locking ring 231 is omitted, the inner side wall of the connector barrel 214 is formed with a third thread (not shown) and the outer side wall of the drive shaft 111 is formed with a fourth thread (not shown). The third thread and the fourth thread are matched with each other to axially separate or fix the connecting cylinder 214 from the driving shaft 111, so that the main disc 14 is axially separated or fixed from the driving shaft 111. As in any arrangement described above, it is sufficient that the main disc 14 can be axially separated from or fixed to the drive shaft 111, so as to facilitate the detachment of the main disc 14. Certainly, preferably, the opening 2141 is formed in the side portion of the connecting cylinder 214, and the axial locking degree between the connecting cylinder 214 and the driving shaft 111 is adjusted by adjusting the size of the opening 2141, so as to axially separate or fix the main disc 14 from the driving shaft 111, so that the main disc 14 is more convenient to assemble and disassemble, thereby solving the problem that the main disc 14 and the driving shaft 111 are inconvenient to assemble and disassemble only in a hammering or knocking manner due to interference design in the prior art, and meanwhile avoiding the problem that the main disc 14 is easily damaged due to violent assembly or disassembly, so that the cost is high.

In addition, the cross section of the locking barrel 2143 is not matched with the cross section of the fixing seat 2142, and the cross section of the locking ring 231 is only matched with the cross section of the locking barrel 2143, so that the locking ring 231 only penetrates through the locking barrel 2143 and is partially or completely supported against the upper surface ring 21421 of the fixing seat 2142 through the lower surface ring surface (not shown) of the locking ring 231. For example, the cross-section of the locking barrel 2143 is a circle with a radius of R4, the cross-section of the fixing seat 2142 is a circle with a radius of R5, and the cross-section of the locking ring 231 is a circle with a radius of R6, wherein R4 < R6 < R5. R4 is less than R6 to ensure that the locking ring 231 can be sleeved on the locking barrel 2143, and R6 is less than R5 to ensure that the locking ring 231 is only sleeved on the locking barrel 2143 and abuts against the fixing base 2142. Of course, the shape of the cross section may be an irregular pattern as long as the locking ring 231 is only sleeved on the locking barrel 2143 and abuts against the fixing seat 2142.

Referring to fig. 4, 5 and 7, the connecting tube 214 extends into the loading port, and the locking ring 231 is sleeved on the locking tube 2143. One end of the locking ring 231 near the fixing seat 2142 extends radially out of the blocking ring 232 along the connecting cylinder 214, so as to form an annular liquid inlet area 233 for liquid communication between the blocking ring 232 and the annular cover 22, that is, the annular liquid inlet area is defined by the outer ring of the blocking ring 232 and the inner ring of the annular cover 22. An annular fluid outlet 1232 formed at the bottom of the fluid conducting device 12 extends partially into the annular fluid intake region 233, and the fluid conducting device 12 delivers fluid to the annular fluid intake region 233 through the annular fluid outlet 1232, thereby delivering fluid to the main tray 14. The disk body 21 and the blocking ring 232 are mutually enclosed outside the fixing seat 2142 to form a liquid buffer region J, and the liquid buffer region J is specifically formed on the radial inner side of the annular accommodating cavity a and can be regarded as a part of the annular accommodating cavity a. When the liquid flows into the annular accommodating cavity a through the annular liquid inlet region 233, due to a large liquid flow rate or a high liquid flow speed, a part of the liquid flows to the radial outer side of the disc body 21 when the liquid collides with the disc body 21, and the other part of the liquid flows to the radial inner side of the disc body 21. The semi-closed configuration of the annular cover 22 with respect to the disk 21 provides a shielding effect for the vertically injected liquid, so as to ensure that the liquid flowing to the radial outside of the disk 21 does not directly splash out of the main disk 14, but is guided by the annular cover 22 to flow along the contour of the lower surface of the annular cover 22 and flow out to the edge of the disk 21 through the flow channel C. While another portion of the liquid flowing radially inward of the disk 21 flows to the buffer region J to be directed by the buffer region J to exit through the flow channel C toward the edge of the disk 21. Specifically, the liquid flows toward the center of the tray body 21, and the inwardly flowing liquid is caused to axially spread along the contour of the fixing seat 2142 by the coanda effect, and the liquid is guided to flow to the flow channel C along the flow direction E by the blocking effect of the blocking ring 232, so that the liquid flows to the edge of the tray body 21 along the flow channel C. The two parts of liquid separated from the vertically injected liquid are buffered and guided in the annular accommodating cavity A formed by the disc body 21 and the annular cover body 22 in a surrounding manner, so that the purpose of uniform flow of the liquid in the annular accommodating cavity A is realized. The semi-closed tray 21 is closed by the annular cover 22 to shield the vertically injected liquid from splashing and ensure that the liquid does not flow directly out of the main tray 14. The blocking ring 232 blocks the liquid from axially spreading, so as to protect the internal components of the centrifugal atomization device 1000, and prevent the liquid from damaging the internal components of the centrifugal atomization device 1000. Simultaneously, enclose the liquid buffer area J that closes formation in annular holding cavity A radial inboard through disk body 21 and barrier ring 232, not only realized carrying out the purpose of buffering to the liquid that flows fast, still lead liquid to runner C through liquid buffer area J to thereby lead liquid to the outflow of disk body 21 edge through runner C, thereby realize preventing the condition of liquid jam to flow equalizing of liquid, with the atomization effect of final assurance liquid.

Referring to fig. 5, the liquid inlet is provided with a baffle 223 along the axial extension direction of the connecting cylinder 214, and the axial height of the baffle 223 is greater than that of the stop ring 232, so as to prevent the liquid from splashing outside away from the centrifugal atomization device 1000 when being conveyed to the main tray 14 along the flow direction B.

Referring to fig. 2, the side of the disc body 21 facing the annular cover 22 is configured with two circles of ribs, namely, the atomizing rib 211 and the flow guiding rib 212 from inside to outside. The supporting portion 213 is disposed between the atomizing rib 211 and the flow guiding rib 212, that is, the atomizing rib 211 is disposed on the radial outer side of the annular receiving cavity a, and the flow guiding rib 212 is disposed on the radial inner side of the annular receiving cavity a. The liquid in the annular accommodating cavity a is divided by the flow guide ribs 212 arranged on the radial inner side of the annular accommodating cavity a, so that the liquid is equalized again. The guide ribs 212 are arranged in a radial annular mode, so that the problem that liquid is blocked due to small intervals between adjacent guide ribs 212 or liquid is blocked due to impurities such as aquatic plants in the liquid when the liquid flow is large is solved, the flow equalizing effect of the guide ribs 212 on the liquid is better guaranteed, and the better atomizing effect is finally achieved. The liquid flowing out of the annular accommodating cavity A is atomized by the atomizing ribs 211 arranged on the radial outer side of the annular accommodating cavity A, so that a better atomizing effect is finally realized.

The fixing portion 221 is disposed at the edge of the annular cover 22, and the supporting portion 213 may be disposed in a specific manner such that the supporting portion 213 is disposed between two adjacent flow guide ribs 212, that is, the flow guide ribs 212 are fully paved in the annular accommodating cavity a; the inner part of the annular accommodating cavity a may be provided with the flow guide rib 212, so long as the flow guide rib 212 and the annular accommodating cavity a can achieve twice flow equalization of the liquid flowing from the liquid guide device 12 into the main tray 14, so as to ensure the final atomization effect. In addition, can also guarantee to be apart from certain distance between supporting part 213 and the atomizing rib 211, namely, form clearance (not sign) between annular accommodation cavity A and the atomizing rib 211 to the condition that leads to liquid jam when there are impurity such as cotton-shaped pasture and water in appearing in the liquid to the clearance of impurity, promptly, to the cleaing away of the cotton-shaped pasture and water of winding on atomizing rib 211. Meanwhile, the axial height of the edge of the annular cover 22 is greater than or equal to the axial height of the flow guide rib 212 to ensure that the cross section of the flow channel C is as large as possible, thereby being beneficial to discharging the flocculent aquatic weeds in water and also avoiding the blockage of the liquid due to the small flow channel C.

Referring to fig. 1, 7 and 8, the centrifugal atomizer 1000 further includes a ring rib 215 and a sealing ring 15 disposed at the bottom of the main tray 14. The annular rib 215 and the main tray 14 may be an integral structure and may be formed by injection molding or other forming processes. Of course, the annular rib 215 may be a separate component from the main tray 14. The end surface of the sealing ring 15 facing the main disc 14 is recessed with an annular groove 151 matching the annular rib 215. Annular rib 215 extends at least partially into circumferential groove 151 to form a sealing area (not identified) to prevent fluid flow into drive shaft 111 by wedging annular rib 215 with circumferential groove 151. The annular rib 215 and the annular groove 151 form a gap F therebetween, and when the driving shaft 111 extended from the driving assembly 11 drives the main tray 14 to rotate, the annular rib 215 is driven to rotate in the gap F formed between the annular rib 215 and the annular groove 151. The aforementioned clearance F may be considered as an axial clearance and/or a radial clearance of the annular rib 215 and the annular groove 151. Therefore, even if liquid enters the inner side of the bottom of the main disc body 14, the liquid stops flowing under the sealing action of the annular rib 215 and the annular groove 151, and the liquid is thrown out by the annular rib 215 along with the high-speed rotation of the main disc body 14, so as to further prevent the liquid from flowing to the driving shaft 111 or the auxiliary shaft 112 and spreading upwards, thereby achieving the purpose of protecting the internal components (such as coils, circuit boards, bearings and the like) of the centrifugal atomization device 1000. The cross-sectional shapes of the ring groove 151 and the annular rib 215 in the radial direction may be arbitrarily defined as long as partial or complete engagement of the ring groove 151 and the annular rib 215 with each other can be achieved. The sealing area is formed by a ring groove 151 and a ring rib 215, specifically, the ring groove 151 is arranged on the sealing ring 15, and the ring rib 215 is arranged on the main disc body 14; it is also possible that the ring rib 215 is provided on the sealing ring 15 and the ring groove 151 is provided on the main disc 14; but may be spaced from each other as long as it is possible to achieve that the annular rib 215 and the annular groove 151 are wedged into each other to form a sealing area to prevent liquid from flowing into the driving shaft 111. The sealing ring 15 is sleeved on the auxiliary shaft 112 extending from the axis of the driving shaft 111, a screw hole G is formed at an end portion of the auxiliary shaft 112, a third connecting hole 152 is formed at the bottom of the sealing ring 15, and the sealing ring 15 is detachably mounted at the bottom of the main tray body 14 by a screw 153 continuously penetrating through the third connecting hole 152 and the screw hole G, so that the sealing ring 15 is detachable.

Referring to fig. 1, 7, 8 and 9, the centrifugal atomization device 1000 further includes an auxiliary disk 16 disposed on a side of the sealing ring 15 away from the main disk 14, and a nut 17 disposed at a bottom of the auxiliary disk 16. The sealing ring 15 extends axially along the auxiliary shaft 112 to form a boss 155 and a connecting column 156 with an external thread, and the auxiliary disc 16 is provided with a first connecting hole 161 from the symmetrical center. The auxiliary tray 16 is sleeved on the boss 155 through the first connection hole 161, and is screwed by the nut 17 matching with the external thread of the connection column 156, so as to detachably connect the auxiliary tray 16 to the sealing ring 15. The nut 17 may be a hand nut or other nut that requires tools for installation, and preferably, a hand nut is used in this embodiment to facilitate quick assembly and disassembly, so as to improve maintainability of the centrifugal atomization device 1000.
