Detailed Description

In order to make the technical problems, technical solutions and advantageous effects solved by the present invention more clearly apparent, the present 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 merely illustrative of the invention and are not intended to limit the invention.

It is to be understood that the terms "upper", "lower", "left", "right", "front", "rear", "middle", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are only for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, should not be construed as limiting the present invention.

As shown in fig. 1 and fig. 2, an air duct structure 1 of an atomizer according to an embodiment of the present invention includes a liquid storage box 11 having an atomizing space 111, and an air duct 12 having a flow passage through hole 121; the air duct pipe 12 is connected with the liquid storage tank 11, and an air flow channel for blowing atomized particles in the atomization space to flow is formed after air provided by the air duct pipe 12 enters the atomization space 111; the liquid storage tank 11 further comprises a diversion channel 13, an outlet of the diversion channel 13 is communicated with the spray opening 112, and an inlet of the diversion channel 13 is positioned in the atomization space 111 and faces away from the air flow channel (i.e. the air in the air flow channel does not face the inlet of the diversion channel 13). It can be understood that the air flow channel in the present embodiment is the flow direction of the air just after the air enters the atomizing space 111 from the outlet of the flow channel through hole 121, and not the flow direction of the air in other parts of the atomizing space except for 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 atomization space 111, the number of the guide channels 13 may be multiple, and the number of the spray outlets 112 may also be multiple. And each flow guide channel 13 may correspond to one spray outlet 112.

Further, the number of the spray outlets 112 and the flow guide channels 13 can be set to be multiple (2, 4, 6, etc.) according to actual requirements.

Specifically, the working principle of the air duct structure 1 of the atomizer is as follows: in a working state, under the action of the ultrasonic atomization device 2, liquid in the atomization space 111 is changed into atomized particles with different diameters, and the atomization space 111 is filled with the atomized particles; the air duct 12 provides air and enters the atomizing space 111 to form an air flow passage for blowing atomized particles, and the direction of the inlet of the flow guide passage 13 deviates 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 is sprayed to the external environment from the spray opening 112 through the flow guide passage 13 after flowing a section of path in the atomizing space 111. In the process that the atomized particles in the atomizing space 111 are blown by the flow passage through holes 121 through the air flow passage, the atomized particles with larger diameters fall on the bottom of the atomizing space 111 under the addition of the gravity and the wind force of the atomized particles, and the atomized particles with smaller diameters can flow along with the air and are sprayed to the external environment from the atomizing nozzle 112 through the flow guide passage 13. Thereby the quality of atomizer spun atomized particles and the experience of product are felt has been improved, the potential safety hazard that the atomizer spun major diameter atomized particles caused has been 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 communicating the atomizing space 111 and the annular mounting space, and the air provided by the air duct pipe 12 enters the atomizing space 111 through the air outlet 11431 to form an air flow duct. It is understood that the protrusion 1141 is inserted into the flow passage through hole 121 when the duct pipe 12 is installed in the annular installation space.

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 flow passage through hole 121 can be blown into the atomization space 111 from the top end of the air duct 12. Further, the annular surrounding arm 1143 is installed on the top of the liquid storage tank 11 and located outside the protruding portion 1141, and the annular surrounding arm 1143 is spaced from the protruding portion 1141, and the top of the runner pipe 12 can be inserted into the annular installation space; the annular surrounding arm 1143 is provided with an air outlet 11431 communicating the atomizing space 111 and the annular mounting space, specifically, the air flowing out from the flow guide channel 13 enters the atomizing space 111 from the air outlet 11431 through the annular mounting space, and an air flow passage entering the atomizing space 111 is formed at the air outlet 11431. In the invention, the air duct structure 1 of the atomizer increases the flowing distance of the 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 box 11 further includes an air outlet channel 134, the air outlet channel 134 communicates with the air outlet 11431 and the atomization space 111, and similarly, the air outlet channel 134 may be embedded in the atomization space 111 or may be a part of the atomization 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 facing the bottom of the liquid storage tank 11 after passing through the air outlet channel 134. That is, after the air flow channel formed by the air outlet 11431 passes through the air outlet channel 134, the air outlet channel 134 has a certain length, and the direction of the air flow channel can be controlled, so that the air flow channel with the main flow direction facing to the bottom of the liquid storage box 11 is formed, and when the air flow channel drives the atomized particles to flow, the larger atomized particles are more easily blown to the bottom of the liquid storage box 11, i.e. the larger atomized particles return to the bottom of the atomizing space 111 to be re-atomized, and the smaller particles flow along with the air flow channel all the time and are ejected from the atomizing nozzle 112 through the diversion channel 13 under the action of the air pressure difference, so as to ensure the small diameter of the blown atomized particles.

In an alternative embodiment, the spray 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 directed toward the bottom of the liquid storage tank 11, so that the entire flow path of the air is first directed toward the bottom of the liquid storage tank 11, and then directed toward the top of the liquid storage tank 11, during this process, the atomized particles with relatively large diameters will almost all be returned to the liquid again due to the gravity and/or the wind force, and only the atomized particles with the diameters meeting the requirement (i.e., can always flow along with the air) will be sprayed out through the spray opening 112.

As shown in fig. 4, the annular surrounding arm 1143 is provided with a plurality of partition plate groups 131 around the end surface away from the protruding portion 1142 at intervals, optionally, the end surface of the annular surrounding arm 1143 away from the protruding portion 1142 is an annular surface, the plurality of partition plate groups 131 are arranged around and at intervals on the annular surface, each partition plate group 131 includes a first partition plate 132 and a second partition plate 133, and one side of the first partition plate 132 and one side of the second partition plate 133 away from the annular surrounding arm 1143 abut 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 surrounding arms 1143, the inner wall of the liquid storage tank 11 and the first and

second partitions

132 and 133 of the same partition group 131 form the diversion passage 13.

The annular surrounding arm 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 the air outlet channel 134.

Optionally, because the partition plate groups 131 are arranged at intervals, and the first partition plate 132 and the second partition plate 133 in the partition plate group 131 are also arranged at intervals, the flow guide channel 13 is formed at intervals between the first partition plate 132 and the second partition plate 133 in the same partition plate group 131, and the air outlet channel 134 can be formed at intervals between the first partition plate 132 of the partition plate group 131 and the second partition plate 133 of the adjacent partition plate group 131. The whole structure is simple and exquisite, the material cost can be effectively reduced, and different required channels are provided to adjust the flow direction of the 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; that is, the first partition 132 and the second partition 133 each extend downward, that is, the opening of the guide passage 13 extends toward the bottom of the liquid storage tank 11.

The air flowing out of the flow passage through hole 121 flows out of the air outlet 11431 through the annular mounting space; the air flowing out from the air outlet 11431 flows along the air outlet channel 134 toward the bottom of the liquid storage box 11, and drives the atomized particles in the atomization space 111 to flow; the atomized particles flow through the diversion channel 13 toward the top of the liquid storage tank 11 and are sprayed out to the environment through the spray outlet 112. Specifically, the flow passage through hole 121 enters the air outlet channel 134 through the air outlet 11431, the air in the air outlet channel 134 drives the atomized particles in the atomization space 111 to flow downward, wherein the atomized particles with larger diameter are more easily blown down to the bottom of the atomization space 111 under the addition of their own gravity and wind force; wherein the atomized particles with smaller diameter flow upwards and are sprayed from the spray opening 112 to the external environment through the flow guide channel 13; thereby further improving the quality of the atomized particles sprayed by the atomizer and the experience of the product, and avoiding the potential safety hazard caused by the atomizer matching large-diameter atomized particles.

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 installed at opposite ends of the outer tube 113, the air duct top plate 114, and the air duct bottom plate 115 enclose the atomizing space 111 therebetween, and the spray opening 112 is disposed on the air duct top plate 114; understandably, the spray opening 112 is disposed at a connection position of the air duct top plate 114 and the outer tube 113, that is, at an outer edge of the top of the outer tube 113, so that the air duct 12 blows air into the atomizing space 111 from a middle portion of the atomizing space 111, atomized particles in the atomizing space 111 are driven by the wind to float in the atomizing space 111, and the spray opening 112 sprays to an external environment, and the spray opening 112 is disposed at the outer edge of the top of the outer tube 113, so that a distance that the atomized particles float in the atomizing space 111 is lengthened, and quality of the atomized particles sprayed by the atomizer is further improved.

A connecting hole is further formed in the air duct bottom plate 115, and a section of the runner pipe 12 penetrates through the connecting hole and extends into the atomization space 111. In the invention, the liquid storage tank 11 has a split structure, and is simple in structure and convenient to install.

In one embodiment, as shown in fig. 2, the top of the liquid storage tank 11 is further provided with an annular diversion part 1142 for guiding the condensate on the inner wall of the air duct top plate 114 into the atomization space 111. As can be appreciated, the annular flow guide portion 1142 is located outside the protruding portion 1141; the annular guiding portion 1142 may be a protrusion 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 when blown by the air, the condensate on the inner surface drops into the atomization space 111 under the action of the annular flow guide portion 1142, the condensate on the inner surface of the air duct top plate 114 is prevented from dropping into the flow passage through hole 121, and therefore, 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 atomizer air channel 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 is understood that a plurality of the ultrasonic atomizing devices 2 (e.g. 2, 4, 6, etc.) may be disposed at the bottom of the liquid storage tank 11, and the ultrasonic atomizing devices 2 may change 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 for blowing air into the flow passage through hole 121, and the fan 3 is mounted on the air passage pipe. It can be understood that the wind direction is used for blowing into the flow passage through hole 121, the wind in the flow passage through hole 121 blows the atomized particles in the atomized space 111 downwards from the top of the flow passage top plate, so that the atomized particles with large diameter in the atomized space 111 are blown and dropped on the bottom of the liquid storage tank, and the atomized particles with smaller diameter are blown and sprayed out from the spray opening 112 through the communicating pipe.

In an embodiment, as shown in fig. 2, the duct pipe is further provided with an enlarged cavity 122 communicating with the flow passage through hole 121, and the enlarged cavity 122 is disposed opposite to the fan 3. It can be understood that the aperture of the expansion cavity 122 is larger than the aperture of the flow passage hole 121, and the air blown by the fan 3 firstly buffers through the expansion cavity 122 and then flows into the atomization space 111 through the flow passage hole 121. In the invention, the design of the enlarged cavity 122 can make the air in the flow passage through hole 121 smoothly circulate, and can effectively reduce noise.

In an 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 hole 121. Understandably, the design of the liquid return opening 123 can make the condensate condensed on the inner wall of the air duct pipe 12 flow out from the liquid return opening 123, thereby ensuring the dryness of the air duct pipe 12 and prolonging the service life of the atomizer.

As shown in fig. 5, the present invention further includes a disinfection robot 10, which includes the atomizer in any of the above embodiments, and the disinfection robot can add disinfection solution into the atomization space 111, form disinfection atomization particles under the action of the ultrasonic atomization device 2, discharge the disinfection atomization particles through the atomization outlet 112, and realize disinfection.
