Detailed Description
The embodiments of the present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1, 2 and 3, in the embodiment of the essential oil atomizing device of the present invention, the essential oil atomizing device comprises a main body 1, a nozzle 2 and a suction pipe 3, wherein the main body 1 comprises a side wall 11 and a bottom surface 12, the bottom surface 12 is disposed in the side wall 11 and is located at a middle position in the height direction of the side wall 11, and a space enclosed by the side wall 11 is divided into an atomizing space (i.e., a space into which the nozzle 2 extends in fig. 1 or a space into which the mist guiding unit 5 is placed in fig. 3) and an installation space (i.e., a space into which the essential oil container 4 is placed or connected in fig. 3); the nozzle 2 is arranged on the side wall 11 and extends into the atomizing space through the side wall 11 for introducing external compressed air into the atomizing space; the suction pipe 3 is arranged on the bottom surface 12, extends from the installation space to the atomization space through the bottom surface 12 (see fig. 3) and is used for guiding the essential oil in the essential oil container 4 into the atomization space, and the arrangement position of the suction pipe 3 is aligned with the tail end (namely one end for ejecting air flow) of the nozzle 2, which enters the atomization space; as shown in fig. 3, the suction pipe 3 includes a pipe head 31 (a portion which is installed on the bottom surface 12 and enters the atomizing space) made of metal and a pipe body 32 (a portion which is located in the installation space and enters the essential oil container 4) made of plastic, the pipe head 31 and the pipe body 32 being connected to each other in the bottom surface 12 and a structure which extends downward from the bottom surface 12; a circular liquid guide hole 311 penetrating the pipe head 31 in the longitudinal direction is formed at the radial center of the pipe head 31; the edge of the circular liquid guiding hole 311 is provided with a first slot 312 extending a set distance along the radial direction of the cartridge 31 to the outer edge of the cartridge 31 and communicating with the circular liquid guiding hole 31, see fig. 2. In some cases in the present embodiment, the first slots 312 include a plurality of first slots 312 uniformly distributed on the circumference of the circular liquid guiding hole 311. In the present embodiment, the purpose of the first slot 312 is to make the dispersion area of the essential oil entering the atomizing space through the suction pipe 3 large when entering, so that even if the positions of the nozzle 2 and the suction pipe 3 are slightly deviated due to tolerance in the manufacturing and installation stages, it can be ensured that the air flow sprayed from the nozzle 2 can form enough negative pressure at the position of the suction pipe 3, enough essential oil is sucked through the suction pipe 3 and carried with the essential oil or a part of the essential oil to hit the side wall, thereby ensuring the stability of the atomizing effect. This cannot be achieved by simply enlarging the radius of the circular liquid conducting hole 311 in the suction tube 3, because a larger radius of the hole means that a larger negative pressure needs to be created to suck up the essential oil liquid, and a larger negative pressure requires a larger velocity of the air flow, which means that the aperture of the air flow conducting hole of the nozzle 2 is smaller without changing other conditions. This can exacerbate the effects of manufacturing or installation tolerances on atomization, making the requirements for the size and location of the nozzle 2 more stringent. By adopting the structure of the first slot 312, the spreading area of the essential oil is enlarged, and the sectional area of the equivalent circular liquid guide hole 311 is slightly increased, so that the error requirement in the manufacturing and installation process is reduced under the condition of not changing other conditions. The enlarged portion (circled portion) in fig. 4 shows in detail the cross-sectional view of the cartridge 31, and it can be seen that the structure of the circular liquid guiding hole 311 and the first slot 312 at the end (end near the nozzle 2) of the cartridge 31, specifically, the first slot 312 extends a set length in the direction of the tube body 32, and then merges with the circular liquid guiding hole 311 into a circular liquid guiding hole with a larger hole diameter (still in the tube body 32) and extends toward the other end (end near the tube body 32) of the cartridge 31, and finally penetrates through the tube body 32. An additional benefit of the above-described construction is that the larger diameter circular liquid conducting bore is narrowed at the end of the cartridge 31 (although its distribution area is not reduced), which allows the liquid to have a greater kinetic energy when it leaves the end of the cartridge 31. It is worth mentioning that in this embodiment, in addition to the above-mentioned structure of the pipe head 31, the tip of the nozzle 2 (the end close to the suction pipe 3) is also structured as such, as is clearly visible in the enlarged portion of fig. 4, and the arrangement of such a nozzle 2 further enhances the above-mentioned advantages, improves the atomisation effect and makes the whole device less sensitive to manufacturing and assembly tolerances.
Therefore, in the present embodiment, in order to further improve the atomization effect, and in order to make the tolerance in the manufacturing and assembling process larger, it is also possible to adopt a structure similar to the tip of the tip 31 of the suction pipe 3 for the nozzle 2, that is, the nozzle 2 includes a nozzle body made of metal and a circular air flow guide hole provided in the middle of the nozzle body, and the edge of the circular air flow guide hole at the tip of the nozzle body is provided with a second slit extending a set distance along the outer edge of the nozzle body in the radial direction of the nozzle body and communicating with the circular air flow guide hole. The second slots include a plurality of second slots uniformly distributed on the circumference of the circular air guide hole, see fig. 4. In other words, in this embodiment, the same structure as the liquid guiding hole in the suction pipe 3 can be adopted for the end of the nozzle 2 (i.e. the end close to the suction pipe 3), so that the air flow from the nozzle 2 can be distributed in the atomizing space in a larger area, and the tolerance requirement in the manufacturing and installation process can be further reduced. Similarly, if the radius of the gas flow guide in the nozzle 2 is simply enlarged, a larger compressor pump would be required to supply the gas. The sectional area shape of the circular gas flow guide hole in the nozzle 2 is changed as described above without changing other conditions. Referring to an enlarged portion of fig. 4, the enlarged portion shows the shape of the gas flow guide hole at the distal end of the nozzle 2 and the sectional structure of the first slot 312 in the cartridge 31, and the structure of the second slot of the nozzle 2 and the structure of the first slot 312 in the cartridge 31 are the same. Due to the above-mentioned structure of the nozzle 2 and the suction pipe 3, the dispersion area of the air flow entering the atomization space can be further increased. It is worth mentioning that the pipe head 31 and the nozzle 2 are made of metal, because the circular gas flow guiding hole and the circular liquid guiding hole have small sizes, and are made of other materials, which are easy to deviate in the production process, thereby causing the effect to disappear or weaken.
As shown in fig. 3 and 4, in this embodiment, the essential oil atomizing device further includes a smoke guiding unit 5, the smoke guiding unit 5 is placed in the atomizing space, and guides the atomized liquid formed by the essential oil entering the atomizing space through the suction pipe 3 to the upper part of the atomizing space according to a mist outlet channel arranged inside the atomizing unit 5, and overflows the atomizing space. It is worth mentioning that the smoke guiding unit 5 plays a role of guiding smoke on one hand and also plays a role of silencing sound on the other hand. This is because the second slit is provided on the nozzle 2 to enlarge the spreading area of the air flow into the atomizing space, so that the noise of the air flow is increased (because it flows through the irregularly shaped guide hole), and the smoke guide unit 5 is provided to reduce the noise in order to eliminate the increased noise. To a certain extent, if the nozzle 2 is not provided with a second slot, the smoke guiding unit 5 can also reduce the sound of the essential oil atomizing device due to the air flow, so that the whole device is quieter in operation.
In this embodiment, as shown in fig. 3, the smoke guiding unit 5 includes a truncated-cone-shaped housing 51 whose top and bottom are respectively flat, and the top surface and bottom surface of the truncated-cone-shaped housing are respectively provided with a first channel 52 and a second channel 53 which are communicated with the space enclosed by the truncated-cone-shaped housing 51 and the space outside the housing; an arresting plate 54 is arranged in a space enclosed by the spherical-table-shaped shell 51, and a smoke channel 55 for enabling atomized liquid to pass through the arresting plate 54 is arranged on the arresting plate 54. In the present embodiment, the barrier plate 54 includes a plurality of (for example, two), each barrier plate 54 is respectively disposed at different heights in the space enclosed by the frustum-shaped housing 41, and the positions of the smoke passages 54 on each barrier plate are staggered from each other. With respect to the dimensions of the above-mentioned smoke guide unit 5, when the outer surface of the frustum-shaped housing 51 is placed in the atomization space, the protruding position of the outer surface (i.e. the middle position of the sphere) is in contact with the inner surface of the atomization space, so that the atomized liquid does not overflow through between the frustum-shaped housing and the side wall. Furthermore, the smoke guiding unit 5 further comprises a supporting surface 56, wherein the supporting surface 56 is arranged on the outer surface of the frustum-shaped housing 51 and is in contact with the bottom surface 12, and the supporting surface 56 is arranged opposite to the nozzle 2 and blocks the airflow introduced by the nozzle 2. That is, when the air flow enters the atomization space through the circular air flow guide hole and the second slit in the nozzle 2, a negative pressure is first formed at the tip (end not connected to the tube body 32) of the tube head 31 of the suction tube 3, so that the essential oil liquid in the essential oil container 4 enters the atomization space through the suction tube 3, collides with the air flow at the tip of the tube head 31, and is carried by the air flow and collides with the upper support surface 56, thereby achieving atomization of the essential oil liquid.
In addition, as shown in fig. 3, the essential oil atomization device further comprises a cover plate 6, the cover plate 6 is sleeved on the top of the side wall 11, a mist outlet 61 is arranged in the middle of the cover plate 6, and the first channel 52 extends upwards and is communicated with the mist outlet 61; meanwhile, as shown in fig. 1 and 4, the bottom surface 12 is provided with an oil filtering gap 14, and the barrier plate 54 is provided with an oil filtering hole 57. The oil filter gap 14 and the oil filter holes 57 function to enable the larger atomized particles of essential oil condensed thereon to automatically drip down after becoming liquid and finally return to the essential oil container 4 to save the amount of essential oil used.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
