Detailed Description

In order to make the technical problems, technical schemes and beneficial effects solved by the invention more clear, the invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.

It is to be understood that the directions or positional relationships indicated by the terms "upper", "lower", "left", "right", "front", "rear", "middle", etc., are based on the directions or positional relationships shown in the drawings, are merely for convenience of description and simplification of the description, and do not indicate or imply that the apparatus or element in question must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention.

As shown in fig. 1 and 2, an atomizer air duct structure 1 according to an embodiment of the present invention includes a liquid storage tank 11 provided with an atomization space 111, and an air duct pipe 12 provided with a flow passage through hole 121; the air duct pipe 12 is connected with the liquid storage tank 11, and an air flow passage for blowing atomized particles in the atomization space to flow is formed after the air supplied by the air duct pipe 12 enters the atomization space 111; the liquid storage tank 11 further includes a diversion channel 13, an outlet of the diversion channel 13 is communicated with the spraying opening 112, and an inlet of the diversion channel 13 is located in the atomization space 111 and faces away from the air flow channel (i.e. air in the air flow channel is not toward the inlet of the diversion channel 13). It should be understood that the air flow channel in this embodiment is the flow direction of the air when the air just enters the atomizing space 111 from the outlet of the flow channel through hole 121, and is not the flow direction of the air in other positions of the atomizing space except the outlet of the flow channel through hole 121.

In an alternative embodiment, the air duct 12 extends from the bottom of the liquid storage tank 11 into the atomizing space 111, and the number of the diversion channels 13 may be multiple, and the number of the spray openings 112 may also be multiple. And each diversion channel 13 may correspond to one spray opening 112.

Further, the number of the spraying openings 112 and the number of the diversion channels 13 may be multiple (2, 4, 6, etc.) according to actual requirements.

Specifically, the operating principle of this atomizer wind channel structure 1 is: in the working state, the liquid in the atomization space 111 is changed into atomized particles with different diameters under the action of the ultrasonic atomization device 2, and the atomization space 111 is filled with the liquid; the air duct pipe 12 provides air and enters the atomization space 111, and forms an air flow passage for blowing atomized particles, and the inlet of the flow guide passage 13 is arranged in a direction deviating from the air flow passage, so that the air blown out from the flow passage through hole 122 does not directly enter the flow guide passage 13, but needs to flow a certain path in the atomization space 111 before being sprayed from the spray opening 112 to the external environment through the flow guide passage 13. In the process that the atomized particles in the atomization space 111 are blown through the air flow passage through hole 121, atomized particles with larger diameters will fall on the bottom of the atomization space 111 under the addition of the gravity and the wind force, and atomized particles with smaller diameters can flow along with the wind and then be sprayed to the external environment from the spraying opening 112 through the diversion channel 13. Therefore, the quality of atomized particles sprayed by the atomizer and the experience of products are improved, and potential safety hazards caused by the atomized particles with large diameters sprayed by the atomizer are avoided.

In one embodiment, as shown in fig. 1, 2 and 4, the top of the liquid storage tank 11 is further provided with an annular surrounding arm 1143; the annular surrounding arm 1143 is provided with an air outlet 11431 which communicates the atomization space 111 and the annular installation space, and the air provided by the air duct pipe 12 enters the atomization space 111 through the air outlet 11431 to form an air flow passage. It will be appreciated that when duct tube 12 is mounted in the annular mounting space, projection 1141 is embedded in flow passage through hole 121.

Further, the protruding portion 1141 is disposed at a middle position of the top of the liquid storage tank 11, and a predetermined distance is left between the top of the liquid storage tank 11 and the top of the air duct 12, so that the air in the air passage through hole 121 can be blown into the atomizing space 111 from the top end of the air duct 12. Further, the annular enclosing arm 1143 is mounted on the top of the liquid storage tank 11 and is located outside the protruding portion 1141, and the annular enclosing arm 1143 is spaced from the protruding portion 1141, and the top of the flow channel pipe 12 may be inserted into the annular mounting space; the annular surrounding arm 1143 is provided with an air outlet 11431 communicating the atomizing space 111 and the annular installation space, specifically, the air flowing out of the flow guiding channel 13 passes through the annular installation space from the air outlet 11431 into the atomizing space 111, and forms an air flow channel at the air outlet 11431 into the atomizing space 111. In the invention, the atomizer air duct structure 1 increases the flowing distance of atomized particles in the atomizing space 111, thereby further improving the quality of the atomized particles sprayed by the atomizer.

As shown in fig. 1 and 4, the liquid storage tank 11 further includes an air outlet channel 134, where the air outlet channel 134 communicates with the air outlet 11431 and the atomizing space 111, and similarly, the air outlet channel 134 may be embedded in the atomizing space 111, or may be a part of the atomizing space 111, which is not limited herein. In an alternative embodiment, the air flow path of the air outlet 11431 forms an air flow path with a main flow direction toward the bottom of the liquid storage tank 11 after passing through the air outlet channel 134. That is, after the air flow passage formed by the air outlet 11431 passes through the air outlet passage 134, the air outlet passage 134 has a certain length, so that the direction of the air flow passage can be controlled, and the air flow passage with the main flow direction facing the bottom of the liquid storage tank 11 is formed, so that when the air flow passage drives atomized particles to flow, the atomized particles larger than the air flow passage are more easily blown to the bottom of the liquid storage tank 11, that is, return to the bottom of the atomizing space 111 to be atomized again, and the small particles flow along with the air flow passage all the time and are sprayed out from the spray opening 112 through the flow guide passage 13 under the action of air pressure difference, so as to ensure the small diameter of the blown atomized particles.

In an alternative embodiment, the spraying opening 112 may be specifically disposed at the top of the liquid storage tank 11, and the inlet of the diversion channel 13 is also oriented towards the bottom of the liquid storage tank 11, so that the flow path of the whole air is first oriented towards the bottom of the liquid storage tank 11, and then oriented towards the top of the liquid storage tank 11, in this process, the atomized particles with relatively large diameters will almost return to the liquid under the action of gravity and/or wind force, and only the atomized particles with diameters meeting the requirement (that is, capable of always flowing with the air) will be sprayed out through the spraying opening 112.

As shown in fig. 4, the annular enclosing arm 1143 is provided with a plurality of partition board groups 131 at intervals on the end surface far away from the protruding portion 1142, optionally, the end surface of the annular enclosing arm 1143 far away from the protruding portion 1142 is an annular surface, the plurality of partition board groups 131 are provided on the annular surface at intervals in a surrounding manner, each partition board group 131 comprises a first partition board 132 and a second partition board 133, and one side of the first partition board 132 and the second partition board 133 far away from the annular enclosing arm 1143 is abutted against the inner wall of the liquid storage tank 11. Alternatively, the first partition 132 and the second partition 133 may be fixed to the inner wall of the liquid storage tank 11 and abut against the annular surrounding arm 1143, which is not limited herein.

It will be appreciated that the annular peripheral arm 1143, the inner wall of the liquid storage tank 11, and the first and

second baffles

132, 133 of the same baffle group 131 form the flow-guiding channel 13.

The annular surrounding arms 1143, the inner wall of the liquid storage tank 11, the first partition 132 of the partition group 131, and the second partition 133 of the adjacent partition group 131 form an air outlet passage 134.

Alternatively, since the partition groups 131 are disposed at intervals, and the first partition 132 and the second partition 133 in the partition groups 131 are disposed at intervals, the first partition 132 and the second partition 133 in the same partition group 131 are disposed at intervals to form the air guiding channel 13, and the first partition 132 of the partition group 131 and the second partition 133 of the adjacent partition group 131 are disposed at intervals to form the air outlet channel 134. The whole structure is simple and exquisite, material cost can be effectively reduced, and different required channels are provided to adjust the flow direction of wind.

In one embodiment, as shown in fig. 4, the first partition 132 and the second partition 133 each extend toward the bottom of the liquid storage tank 11; i.e. the first partition 132 and the second partition 133 each extend downwards, i.e. the opening of the flow guiding channel 13 extends towards the bottom of the liquid storage tank 11.

The wind flowing out from the flow passage through hole 121 flows out from the air outlet 11431 through the annular installation space; the air flowing out from the air outlet 11431 flows along the air outlet channel 134 toward the bottom of the liquid storage tank 11, and drives the atomized particles in the atomized space 111 to flow; atomized particles flow through the diversion channel 13 towards the top of the liquid storage tank 11 and are sprayed through the spray openings 112 towards the external environment. Specifically, the flow passage through hole 121 enters the air outlet channel 134 through the air outlet 11431, and the air in the air outlet channel 134 drives the atomized particles in the atomized space 111 to flow downward, wherein the atomized particles with larger diameters are more easily blown down at the bottom of the atomized space 111 under the addition of the gravity and the wind force of the atomized particles; wherein atomized particles of smaller diameter flow upwardly and are ejected from said spray orifice 112 through said flow-directing channel 13 to the external environment; therefore, the quality of atomized particles sprayed by the atomizer and the experience of products are further improved, and potential safety hazards caused by the fact that the atomizer is matched with atomized particles with large diameters are avoided.

In one embodiment, as shown in fig. 2, the liquid storage tank 11 includes an outer tube 113, and an air duct top plate 114 and an air duct bottom plate 115 mounted at opposite ends of the outer tube 113, the air duct top plate 114 and the air duct bottom plate 115 enclose the atomization space 111, and the spray opening 112 is disposed on the air duct top plate 114; understandably, the spraying opening 112 is disposed at the connection between the air duct top plate 114 and the outer tube 113, that is, at the outer edge of the top of the outer tube 113, so that the air duct 12 blows air into the atomizing space 111 from the middle part of the atomizing space 111, and atomized particles in the atomizing space 111 are driven by the air force to fly in the atomizing space 111, so that the spraying opening 112 sprays into the external environment, and the spraying opening 112 is disposed at the outer edge of the top of the outer tube 113, so that the distance that the atomized particles fly in the atomizing space 111 is prolonged, and the quality of the atomized particles sprayed by the atomizer is further improved.

The duct bottom plate 115 is further provided with a connecting hole, and a section of the runner pipe 12 passes through the connecting hole and extends into the atomization space 111. It can be appreciated that the outer wall of the runner pipe 12 is in sealing connection with the connecting hole, and in the invention, the liquid storage tank 11 is of a split type structure, and has a simple structure and convenient installation.

In an embodiment, as shown in fig. 2, an annular guiding portion 1142 is further provided at the top of the liquid storage tank 11 for guiding the condensate on the inner wall of the air duct top plate 114 into the atomizing space 111. As can be appreciated, the annular deflector 1142 is located outside the boss 1141; the annular flow guiding portion 1142 may be a protruding portion provided on the air duct top plate 114 and protruding toward the atomizing space 111. Specifically, the atomized particles in the atomization space 111 may collect on the inner surface of the air duct top plate 114 and form condensate under the action of the annular flow guiding portion 1142, so that the condensate on the inner surface drops into the atomization space 111, and the condensate drops on the inner surface of the air duct top plate 114 are prevented from dropping into the flow passage through hole 121, and further short circuit of the fan 3 and other components caused by the condensate in the flow passage through hole 121 is avoided, and the service life of the atomizer is prolonged.

As shown in fig. 1 to 4, in another embodiment, the present invention further provides an atomizer, including the above-mentioned atomizer air duct structure 1.

In one embodiment, as shown in fig. 3, the atomizer further comprises at least one ultrasonic atomizing device 2 mounted at the bottom of the liquid storage tank 11. It will be appreciated that the bottom of the liquid storage tank 11 may be provided with a plurality of the ultrasonic atomizing devices 2 (e.g., 2, 4, 6, etc.) depending on the actual arrangement, and the ultrasonic atomizing devices 2 may turn the liquid in the atomizing space 111 into atomized particles.

In one embodiment, as shown in fig. 3, the atomizer further includes a fan 3 blowing air into the flow passage hole 121, and the fan 3 is mounted on the duct tube. As will be appreciated, the wind direction is used to blow into the flow passage through hole 121, and the wind in the flow passage through hole 121 blows the atomized particles in the atomization space 111 downward from the top of the flow passage top plate, so that the atomized particles with large diameter in the atomization space 111 are blown and dropped on the bottom of the liquid storage tank, and the atomized particles with smaller diameter are blown and then ejected from the spray port 112 through the communication pipe.

In an embodiment, as shown in fig. 2, the air duct pipe is further provided with an enlarged cavity 122 that communicates with the flow passage through hole 121, and the enlarged cavity 122 is disposed opposite to the fan 3. It can be appreciated that the aperture of the enlarged cavity 122 is larger than the aperture of the flow passage through hole 121, and the air blown by the fan 3 flows into the atomizing space 111 from the flow passage through hole 121 after being buffered by the enlarged cavity 122. In the present invention, the design of the enlarged cavity 122 can make the air in the flow passage through hole 121 circulate smoothly, and can effectively reduce noise.

In one embodiment, as shown in fig. 2, a liquid return port 123 is disposed at an end of the enlarged cavity 122 away from the flow passage through hole 121. It can be appreciated that, due to the design of the liquid return port 123, condensed condensate condensed on the inner wall of the air duct pipe 12 can flow out from the liquid return port 123, so that the dryness of the air duct pipe 12 is ensured, and the service life of the atomizer is prolonged.

As shown in fig. 5, the present invention further includes a sterilization robot 10 including the atomizer of any of the above embodiments, which can add a sterilization liquid to the atomizing space 111, and form sterilization atomized particles by the ultrasonic atomizing apparatus 2, and discharge based on the spray port 112, and achieve sterilization.
