Description

Technical Field

[0001] The utility model relates to the technical field of spray equipment, in particular to an atomizing component and a fragrance diffuser provided with an air inlet pipe. Background Art

[0002] With the diversification of people's living needs, atomizers for regulating indoor air and aroma diffusers equipped with atomizers are increasingly being used in people's lives. Figure 1 and Figure 2 As shown, the main structure of the atomizer generally includes a bottle body A for storing liquid, the bottle mouth of the bottle body A is sealed and connected with a cover body B, and an atomizing core C is arranged inside the cover body B, and a liquid outlet channel and an air jet channel are respectively arranged inside the atomizing core C, and the outlet of the liquid outlet channel and the outlet of the air jet channel are close to each other and form a certain angle with each other. As for the connection of the atomizing core C, the liquid outlet channel of the atomizing core C is connected with a liquid suction tube D, and the liquid suction tube D extends to the bottom of the inner cavity of the bottle body A, and the air jet channel of the atomizing core C is connected to the air pump through a pipeline. When the air pump is running, the outlet of the air jet channel A high-speed airflow is ejected from the outlet of the bottle body A. When the high-speed airflow blows through the outlet of the liquid outlet channel, a negative pressure is formed at the outlet position of the liquid outlet channel. Under the action of the negative pressure, the liquid inside the bottle body A can enter the liquid outlet channel of the atomization core C through the liquid suction tube D and flow out from the outlet of the liquid outlet channel. The liquid flowing out from the outlet of the liquid outlet channel can just touch the high-speed airflow ejected from the jet channel. The continuously ejected high-speed airflow can hit the liquid flowing out from the liquid outlet channel, causing the liquid to be atomized to form mist. The formed mist can continue to be ejected outward through the spray tube E on the top of the cover body B along with the airflow.

[0003] However, the atomizer of the above structure has always had the problem of low spray volume in actual use. The main reason is that in the process of generating mist, the high-speed airflow sprayed by the atomizer core C flows out quickly, which also causes the problem of insufficient air volume inside the atomizer. In order to solve this problem, the Chinese utility model patent with patent number CN208711985U discloses a spray mechanism. The patented technical solution opens an air return hole connected to the atmosphere on the cover body at the top of the atomizer, so that the outside air can naturally flow into the cover body at the top of the atomizer to replenish the internal air of the atomizer, which helps to improve the atomization efficiency of the atomizer and further increase the spray volume of the atomizer. In order to solve the above problem, the Chinese utility model patent with patent number CN215465310U discloses an atomizer cover and an atomizer core. The patented technical solution opens an air inlet pipe connected to the atmosphere on the atomizer cover at the top of the atomizer. The air inlet pipe can also be used to automatically replenish the internal air of the atomizer during the process of the atomizer spraying mist, effectively increasing the spray volume of the atomizer. Another example is a Chinese utility model patent with patent number CN206151930U that discloses a fragrance diffusion device. The patented technical solution adds two symmetrical strip-shaped through holes on the atomizer cover body at the top of the atomizer, allowing external air to naturally enter the interior of the atomizer through the two through holes, ensuring that the amount of air inside the atomizer is sufficient, thereby helping to improve the atomization efficiency of the atomizer and further increase the spray volume of the atomizer.

[0004] Although the above-mentioned prior art can increase the spray volume of the atomizer, in actual use, since a through hole is directly opened on the cover of the atomizer, the noise generated by the atomizer core located inside the cover during the process of spraying high-speed airflow will also be directly transmitted to the outside through the through hole on the cover, causing the atomizer and the aroma diffuser to generate obvious noise to the outside during operation, which on the one hand affects the user experience, and on the other hand, when the atomizer is tilted, the liquid in the bottle is easy to leak out through the through hole on the cover, which is easy to cause leakage. Utility Model Content

[0005] In order to solve the technical problems existing in the prior art to a certain extent as much as possible, the utility model provides an atomization assembly and a fragrance diffuser provided with an air inlet pipe, which can not only improve the atomization efficiency of the atomizer and increase the atomization amount, but also effectively reduce the noise of the atomizer during operation, and can also avoid the atomizer from leaking liquid to a certain extent.

[0006] The utility model discloses an atomizer assembly provided with an air inlet pipe, comprising an atomizer and a bottle body, wherein the atomizer comprises a cover body and an atomizer core, a through hole is formed on the outer wall of the cover body, and the atomizer is also provided with an air inlet pipe;

[0014] According to the atomizer assembly provided with an air inlet pipe according to the claim, the extension length of the air inlet pipe inside the cover body is 5 mm to 200 mm.

[0015] According to the atomizing assembly provided with an air inlet pipe according to the claim, the cover body is provided with a spray pipe;

[0020] The utility model also provides a fragrance diffuser, wherein the interior of the fragrance diffuser is provided with the above-mentioned atomization component provided with an air inlet pipe.

[0021] The utility model discloses an atomizing assembly provided with an air inlet pipe, in which not only a through hole is opened on the outer wall of the cover of the atomizer, but also an air inlet pipe is additionally provided, so that the air inlet pipe is connected to the through hole inside the cover, so that when the atomizer is working, the outside air can enter the inside of the atomizer through the air inlet pipe, so as to replenish the internal air of the atomizer in real time, thereby ensuring that the atomization efficiency of the atomizer can be improved and the atomization amount can be increased. At the same time, since the air inlet pipe extends a certain length inside the cover, compared with the traditional method of directly opening a through hole on the cover, a narrow pipe space of a certain length is formed, which can be more conducive to limiting the noise in the cover from propagating outward, that is, the noise generated during the atomization process needs to be transmitted outward through the narrow pipe space of a certain length inside the air inlet pipe, so that the internal noise of the cover can be limited, and the noise emitted to the outside by the atomizer during operation can be effectively reduced. In addition, when the atomizer is tipped over, the long strip-shaped air inlet pipe can prevent the liquid in the bottle from leaking directly outward through the through hole inside the cover, thereby avoiding the situation that the atomizer is prone to leakage to a certain extent.

[0036] like Figures 1 to 7 As shown, an atomization assembly provided with an air inlet pipe in this embodiment comprises an atomizer and a bottle body 1, wherein the bottle body 1 stores liquid for forming mist, the atomizer comprises a cover body 3 and an atomization core 2, the atomization core 2 is installed at the bottle mouth on the top of the bottle body 1, and the cover body 3 is installed at the bottle mouth on the top of the bottle body 1, the cover body 3 and the bottle mouth of the bottle body 1 are threadedly connected to each other, so that the cover body 3 can close the bottle mouth of the bottle body 1, and the atomization core 2 is accommodated in the cover body 3, and an installation port 6 suitable for connecting to the air inlet pipe of the air pump is reserved on the outer side of the cover body 3, so that the air inlet pipe of the air pump can be inserted into the interior of the cover body 3 through the installation port 6 and connected to the jet channel of the atomization core 2, and a spray pipe 31 is integrally formed on the cover body 3, and the spray pipe 31 is located above the atomization core 2, so as to allow the mist sprayed by the atomization core 2 to enter the spray pipe 31 upward and be discharged to the outside. In addition, a through hole 5 is formed on the outer wall of the cover body 3 , and the atomizer is also provided with an air inlet pipe 4 , which extends a certain length inside the cover body 3 and is connected to the through hole 5 , so as to allow external air to enter the interior of the atomizer through the air inlet pipe 4 .

[0037] It can be understood that in this embodiment, not only a through hole 5 is opened on the outer wall of the cover body 3 of the atomizer, but also an air inlet pipe 4 is additionally provided, so that the air inlet pipe 4 is connected to the through hole 5 inside the cover body 3. Therefore, when the atomizer is working, the outside air can enter the inside of the atomizer through the air inlet pipe 4, so as to replenish the internal air of the atomizer in real time, thereby ensuring that the atomization efficiency of the atomizer can be improved and the atomization amount can be increased. At the same time, since the air inlet pipe 4 extends a certain length inside the cover body 3, most of the noise generated by the atomization core 2 in the process of ejecting high-speed airflow can be blocked by the outer wall of the long strip-shaped air inlet pipe 4, and only a small part can be transmitted outwardly through the air inlet pipe 4, so that the noise of the atomizer during operation can be effectively reduced. In addition, when the atomizer is tipped over, the long strip-shaped air inlet pipe 4 can prevent the liquid in the bottle body 1 from directly leaking outwardly through the through hole 5 inside the cover body 3, which can avoid the atomizer from leaking easily to a certain extent.

[0038] In one embodiment, specifically, the air inlet pipe 4 extends vertically inside the cover body 3 toward the bottle body 1, so that the air inlet pipe 4 and the cover body 3 can be integrally formed during injection molding, which is convenient for manufacturing. Of course, optionally, the air inlet pipe 4 can also be detachably installed inside the cover body 3, or can be bent inside the cover body 3. After the air inlet pipe 4 is bent inside the cover body 3, it can further prevent the atomizer from leaking easily.

[0039] It should be pointed out that, in the structure of the present embodiment, the air inlet pipe outlet 41 at the lower end of the air inlet pipe 4 (i.e., the pipe opening away from the through hole 5) is located at a height position inside the cover body 3 that is lower than the jet outlet of the atomizer core 2. The technical effect of this structure is that it can prevent the high-speed airflow in the spray area of ​​the atomizer core 2 from easily entering the air inlet pipe 4 through the air inlet pipe outlet 41 along with the mist, and prevent the mist from being discharged to the outside through the air inlet pipe 4, thereby affecting the normal replenishment of the outside air to the inside of the atomizer through the air inlet pipe 4.

[0040] However, in actual applications, since the spray range generated by the nozzle of the atomizer core 2 inside the atomizer product is generally a fan-shaped area, it is not absolutely necessary to set the air inlet pipe outlet 41 at a position lower than the nozzle of the atomizer core 2. Therefore, optionally, the height position of the air inlet pipe outlet 41 at the lower end of the air inlet pipe 4 inside the cover body 3 can also be set to be no more than 5 mm higher than the nozzle of the atomizer core 2. In this way, it can also be ensured that the high-speed airflow ejected from the nozzle of the atomizer core 2 and the mist enter the air inlet pipe 4 through the air inlet pipe outlet 41.

[0041] The air inlet pipe 4 of this embodiment is set as a circular pipe. In theory, the smaller the inner hole diameter of the air inlet pipe 4, the smaller the noise transmitted to the outside when the atomizer is working. However, too small an inner hole will affect the amount of air entering. Therefore, in this embodiment, the pipe opening diameter of the air inlet pipe 4 is preferably set to 0.5mm to 4mm. Within this numerical range, the transmission of the working noise of the atomizer can be well reduced, and sufficient air intake can be provided to the inside of the atomizer. Of course, the air inlet pipe 4 can also be set as an elliptical pipe or a polygonal pipe according to other actual needs, and the opening area of ​​the elliptical pipe or the polygonal pipe is the same as the opening area of ​​the circular pipe mentioned above.

[0042] In addition, in theory, the longer the length of the air inlet pipe 4 is, the smaller the noise emitted to the outside when the atomizer is working. In this embodiment, the extension length of the air inlet pipe 4 is preferably set to 5mm to 200mm. Similarly, in theory, the smaller the inner hole diameter of the spray pipe 31 is, the smaller the noise emitted to the outside when the atomizer is working. However, too small an inner hole will affect the mist output efficiency. Therefore, in this embodiment, the nozzle diameter of the spray pipe 31 is preferably set to 1mm to 4mm.

[0043] Optionally, the present embodiment may further include an airflow driving component for driving the air flow. The airflow driving component may preferably include an air pump or a fan. The exhaust end of the air pump or the fan is connected to the through hole 5 outside the cover body 3 to actively drive air into the air inlet pipe 4, thereby increasing the amount of air entering the inside of the atomizer.

[0044] Alternatively, if Figure 8 and Fig. 9 As shown, a plurality of through holes 5 may be provided on the cover body 3 of the atomizer, and the number of the through holes 5 may be less than or equal to 8. Accordingly, the number of the air inlet pipes 4 is also set to be multiple, and each air inlet pipe 4 is respectively connected to each through hole 5 inside the cover body 3, and each air inlet pipe 4 is distributed at different positions inside the cover body 3. In this way, the air intake efficiency of the external air into the atomizer can be improved, and sufficient air can be ensured inside the atomizer during the spraying process, thereby increasing the atomization amount.

[0045] Based on the above, the present embodiment further provides a fragrance diffuser, wherein the fragrance diffuser is installed with the atomizer assembly with an air inlet pipe of the present embodiment. Since the fragrance diffuser is installed with the atomizer assembly with an air inlet pipe of the present embodiment, the atomization efficiency can be effectively improved and the atomization volume can be increased, so that the amount of mist carrying fragrance components sprayed out can be larger, and the noise of the fragrance diffuser during operation can be effectively reduced, and the fragrance diffuser can be prevented from leaking to a certain extent.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
