Detailed Description
The embodiments of the present invention will be further explained with reference to the drawings.
In the embodiments of the liquid atomizing unit and the liquid atomizing device of the present invention, a precise atomizing device is taken as an example to describe the specific structure of the liquid atomizing unit and the liquid atomizing device.

The external air flow enters the device through the air flow channel 3, atomizes the liquid (in this embodiment, essential oil) in the container 2, passes through the regulation or temporary storage of the mist outlet quantity regulating unit 5, and finally is diffused to the outside of the device through the mist outlet 6, so as to realize the purposes of environment regulation or incense.
Fig. 2 is a schematic sectional view showing the structure of the apparatus in this embodiment, and fig. 3 is an enlarged view showing the structure of the nozzle portion of fig. 2, so that the structural details thereof can be more clearly seen. As can be seen from fig. 2 and 3, the liquid atomizing unit 1 and the container 2 are connected together by screw-fitting, and the connection is not only firm, but also good in sealing property, and is suitable for connecting the container 2 containing volatile essential oil. Fig. 2 also shows the structure of the liquid atomizing unit 1, which includes a housing 11, an atomizing chamber 4 is provided in the housing 11, a mist outlet 6 is provided above the atomizing chamber 4, an airflow channel 3 for guiding airflow outside the housing 11 is provided on the housing 11 on one side of the atomizing chamber 4, and the airflow entering through the airflow channel 3 enters the atomizing chamber 4 through an airflow outlet 72; a liquid retention cavity 73 is further arranged between the airflow outlet 72 and the airflow channel 3, the liquid retention cavity 73 retains liquid supplied through a liquid channel 74, and the airflow passes through the liquid retention cavity 73, so that the liquid is atomized, an airflow and atomized liquid of the atomized liquid are formed, enter the atomization cavity 4 through the airflow outlet 72, and are atomized again in the atomization cavity 4; the liquid atomization unit further comprises a mist outlet amount adjusting unit 5, wherein the mist outlet amount adjusting unit 5 is arranged above the atomization chamber 4 and used for adjusting the mist outlet amount passing through the mist outlet 6.
In the present embodiment, as shown in fig. 2 and 3, the airflow outlet 72 is disposed at one side of the atomizing chamber 4, i.e., at one side of the airflow channel 3, in a sense that the airflow outlet 72 is the end of the airflow channel 3, where the airflow entering the liquid atomizing unit 1 will enter the atomizing chamber 4. As is well known, the air flow through the air flow outlet 72 must have a velocity such that, under the inertial action of the velocity, the atomized liquid entering the atomization chamber 4 through the air flow outlet 72 is atomized again by striking the side wall of the atomization chamber 4 (i.e., the inner surface of the housing 11) opposite (i.e., opposite) the air flow outlet 72.
As shown in fig. 2, in the present embodiment, the mist output adjusting unit 5 includes a mist output adjusting cavity 51, and the mist output adjusting cavity 51 is communicated with the atomizing chamber 4 and accommodates the atomized liquid entering through the atomizing chamber 4; the mist outlet 6 is arranged at the top of the mist outlet amount adjusting cavity 51, and the atomized liquid in the mist outlet amount adjusting cavity 51 is diffused into the space outside the liquid atomizing unit 1 through the mist outlet channel arranged in the mist outlet amount adjusting cavity 51 and the mist outlet 6. Referring to fig. 2, a partition plate 52 is further disposed in the mist outlet amount adjusting cavity 51, the partition plate 52 is disposed at the top of the mist outlet amount adjusting cavity 51 and extends a set distance into the mist outlet amount adjusting cavity 51, and a mist outlet channel is formed by a tail end of the partition plate 52 and a side wall of the mist outlet amount adjusting cavity 51; the mist outlet 6 is arranged at one side of the partition plate 52 and is communicated with the mist outlet channel. That is, the partition plate 52 divides the mist amount adjusting chamber 51 into two spaces having different volumes and communicating with each other at the bottom, and the mist outlet 6 is provided at the top of the space having a smaller volume. From this point of view, the partition plate 52 actually limits the atomized liquid that can reach the mist outlet 6, so that the amount of atomized liquid passing through the mist outlet 6 is limited, and therefore, the partition plate 52 and the side wall of the mist amount adjusting cavity 51 form a mist outlet channel, as shown in fig. 2; meanwhile, most of the atomized liquid entering the mist outlet amount adjusting cavity 51 enters a larger space formed by the partition plate 52 and the side wall on the other side of the mist outlet amount adjusting cavity 51, and a small amount of atomized liquid can enter the mist outlet channel again and is diffused through the mist outlet 6; the majority of the atomized liquid resumes as droplets, falls back into the above-mentioned atomizing chamber 4 and re-enters the container 2 through the above-mentioned atomizing chamber 4. After atomization, the atomized liquid with smaller particles has a faster speed under the same pressure or airflow, so the structures of the mist quantity adjusting cavity 51 and the partition plate 52 actually have the functions of making the dispersed atomized liquid have smaller particles and making mist generation more uniform.
As shown in fig. 2, in the present embodiment, the air flow passage 3 includes an air intake duct 31 and a nozzle 32 connected to the air intake duct 31; the air inlet pipe 31 is embedded in a recess on the side wall of the housing 11 (this structure can be seen from fig. 1 and 2), and one end of the air inlet pipe 31 is located outside the housing 11, so as to connect an air pump arranged outside; the other end of the air inlet pipe 31 is positioned in the recess of the shell 11 and is connected with the nozzle 32 which is also positioned in the recess, the middle of the air inlet pipe 31 is provided with a first through hole 33 which penetrates through the two ends of the air inlet pipe, and the first through hole 33 enables the air flow to enter the nozzle 32 from the outside of the shell 11 through the first through hole 33; the nozzle 32 is provided with a second through hole 34 penetrating both ends thereof and corresponding to the first through hole 33, one end of the second through hole 34 is communicated with the first through hole 33, and the other end is communicated with the liquid retention chamber 73, see fig. 3. In the present embodiment, referring to fig. 3, the radius of the second through hole 34 is changed, and the farther the distance from the other end of the first through hole 33, the smaller the radius. This is done, on the one hand, to control the flow rate of the gas flow and, more importantly, to increase the velocity or pressure of the gas flow so that a negative pressure is created in the liquid retention chamber 73 at its outlet to facilitate the extraction of the liquid in the container 2 into said liquid retention chamber 73.
In this embodiment, the liquid passage 74 includes a suction tube 71, one end of the suction tube 71 is fixedly connected to the bottom of the liquid retention chamber 73 and communicates with the inside of the liquid retention chamber 73, specifically, referring to fig. 3, one end of the suction tube 71 is connected to the liquid retention chamber 73 through a through hole; the other end of the suction pipe 71 extends to a predetermined length to the outside of the liquid atomizing unit 1. In the present embodiment, the outside refers to the direction of the container 2 connected to the liquid atomizing unit 1. When the container 2 is connected to the liquid atomizing unit 1, the other end of the suction pipe 71 extends into the upper container 2 through an opening at the top of the container 2 and is positioned below the liquid level in the container 2.
In this embodiment, in order to facilitate the installation of the container 2 on the liquid atomizing unit 1, the bottom of the liquid atomizing unit 1 is provided with a container installation position with internal threads, and the container 2 is rotatably fixed on the liquid atomizing unit 1 through threads arranged on the outer wall thereof; wherein the other end of the straw extends below the level of the liquid in the container 2, see fig. 2.
Furthermore, as mentioned above, during the atomization and the mist generation, droplets are continuously focused in the atomization chamber 4, while the atomization chamber 4 of the liquid atomization unit 1 is provided with a bottom surface 41, see fig. 4, on which the droplets are finally deposited, the bottom surface 41 being located above the opening of the container 2, so that the atomization chamber 4 is spaced from the container mounting location, so that the atomization chamber 4 forms a single chamber. In order to enable the above-mentioned droplets to be returned to the container 2 for re-use, said bottom surface 41 is provided with a plurality of small holes 42 for facilitating the recovery of the liquid on said bottom surface 41 into said container 2. Meanwhile, in some cases in the present embodiment, for example, when the liquid atomizer is toppled over for some reason, the bottom surface 41 and the plurality of small holes 42 also have a certain blocking effect on the liquid in the container 2, so that even in the case of toppling over or turning upside down, the liquid in the container 2 enters the atomizing chamber 4 (since the atomizing chamber 4 is communicated with the mist outlet 6, the liquid will overflow from the mist outlet 6 after entering the atomizing chamber 4) at a very slow speed or will not enter the atomizing chamber 4. This is because if the liquid is poured in the presence of an air flow input, this input air flow will enter the nebulization chamber 4 directly, with a certain pressure, blocking or delaying the liquid from entering the nebulization chamber 4 through the above mentioned small holes 42; the closed bottom of the container 2 also makes it more difficult for the liquid in the container 2 to enter the cavity 4 through the small hole 42 in the absence of an air flow input. This arrangement thus also substantially prevents liquid in the container 2 from rapidly escaping through the mist outlet 6 in the event that the device is tipped over.
The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
