Detailed Implementation

[0032] To facilitate understanding of this utility model, the specific embodiments of this utility model will be described in more detail below with reference to the accompanying drawings.

[0033] Unless otherwise specified or defined, the terms "first," "second," etc., used in this document are for distinguishing names only and do not represent a specific number or order.

[0034] Unless otherwise specified or defined, the term “and / or” as used herein includes any and all combinations of one or more of the associated listed items.

[0035] It should be noted that when a component is considered "fixed" to another component, it can be directly fixed to the other component or there can be an intervening component; when a component is considered "connected" to another component, it can be directly connected to the other component or there can be an intervening component; when a component is considered "mounted" on another component, it can be directly mounted on the other component or there can be an intervening component; when a component is considered "placed" on another component, it can be directly placed on the other component or there can be an intervening component.

[0036] This utility model proposes an atomizing cap 100, such as Figures 1 to 3 As shown, it includes: a housing 10 and an air intake assembly 5. The air intake assembly 5 includes an air intake seat 51, a limiting plate 53, and a sealing plug 54. The air intake seat 51 is installed on the housing 10, and the sealing plug 54 is installed inside the air intake seat 51. The sealing plug 54 has an air intake channel 52. The first end of the air intake channel 52 communicates with the inside of the housing 10, and the second end of the air intake channel 52 is used to connect to an air pump. The limiting plate 53 is detachably engaged with the air intake seat 51 and is used to abut against the sealing plug 54.

[0037] Specifically, the sealing plug 54 is made of an elastic material. When the sealing plug 54 is installed on the intake seat 51, it can squeeze the intake seat 51 during installation, achieving flexible contact between the sealing plug 54 and the intake seat 51 and preventing gaps. Then, the limiting plate 53 is used to hold the sealing plug 54 onto the intake seat 51, thus fixing it in place. Furthermore, the limiting plate 53 and the intake seat 51 are detachably connected. When the sealing plug 54 ages, the limiting plate 53 can be removed from the intake seat 51, allowing the sealing plug 54 to be removed and replaced with a new one. Then, the limiting plate 53 is installed back onto the intake seat 51 to limit the sealing plug 54.

[0038] Preferably, the air intake seat 51 includes a support body 511 and a limiting block 512. A sealing plug 54 is installed inside the support body 511, and the limiting block 512 is installed on the outer wall of the support body 511. The limiting block 512 extends along the outer edge of the support body 511 and is bent. A groove 514 is formed between the inner side of the limiting block 512 and the outer side of the support body 511. The limiting plate 53 engages with the groove 514 and is at least partially used to abut against the sealing plug 54. Specifically, the mounting cavity of the support body 511 is used to accommodate the sealing plug 54. The sealing plug 54 is inside the support body 511 and fits against the inner wall of the support body 511. The outer surface of the sealing plug 54 is on the same plane as the outer surface of the support body 511. The limiting block 512 is set on the outer end of the support body 511 and has a groove 514 between it and the support body 511. The limiting plate 53 is inserted into the groove 514 and abuts against the sealing plug 54, thereby fixing the sealing plug 54 inside the support body 511. The cooperation between the limiting plate 53 and the groove 514 can improve the convenience of the cooperation between the limiting plate 53 and the air intake seat 51, and at the same time improve the stability of the sealing plug 54 on the air intake seat 51. When the air pump's air intake pipe is inserted into the sealing plug 54, the outer wall of the air intake pipe squeezes the inner wall of the sealing plug 54, and the air intake pipe and the sealing plug 54 are flexibly connected, further improving the sealing performance of the connection between the air intake pipe and the atomizing cover 100.

[0039] Preferably, the air intake seat 51 further includes a locking block 513. The first end of the locking block 513 is mounted on the support body 511, and the second end of the locking block 513 abuts against the limiting plate 53. The locking block 513 has a barbed structure. Specifically, the limiting plate 53 has a through hole for the second end of the locking block 513 to pass through. When the limiting plate 53 is inserted into the slot 514, the second end of the locking block 513 passes through the limiting plate 53, causing the limiting plate 53 to abut against the second end of the locking block 513. Since the locking block 513 has a barbed structure, the locking block 513 hooks the limiting plate 53, further improving the stability of the limiting plate 53 in the slot 514.

[0040] In some embodiments, the outer casing 10 includes a first cover 1, a second cover 2, and an atomizing core 4. The second cover 2 is mounted on the first cover 1. The first cover 1 has a first chamber 11, and the second cover 2 has a second chamber 21 and a spray nozzle 31. The first chamber 11, the second chamber 21, and the spray nozzle 31 are sequentially connected. The atomizing core 4 is mounted inside the first cover 1, and an air inlet seat 51 is mounted on the second cover 2. An air inlet channel 52 is connected to the first end of the atomizing core 4, and the second end of the atomizing core 4 is connected to the first chamber 11. Specifically, the first cover 1 is used to connect an atomizing bottle, and the atomizing core 4 is mounted on the first cover 1. The atomizing position 41 of the atomizing core 4 is located in the first chamber 11. High-pressure gas from the air pump is delivered to the atomizing core 4 through the air inlet assembly 5 and disperses the essential oil in the atomizing core 4, forming a particulate spray in the first chamber 11. The particulate spray flows out through the second chamber 21 to the spray nozzle 31, thereby improving the surrounding environment.

[0041] Preferably, the atomizing cover 100 further includes a spray tube 3, with a spray nozzle 31 disposed at the first end of the spray tube 3, and the second end of the spray tube 3 mounted on the second cover 2; the center of the first cover 1 and the center of the second cover 2 are offset, and the spray nozzle 31 is disposed away from the first cover 1. Specifically, when the atomizer needs to be installed in the storage housing, after the first cover 1 is connected to the atomizing bottle, the atomizing bottle can be locked in the receiving groove of the storage housing, while the second cover 2 is away from the receiving groove of the storage housing, and the spray tube 3 is mounted on the second cover 2, with the spray nozzle 31 of the spray tube 3 extending out of the storage housing, so that the first cover 1 and the second cover 2 adapt to the spatial design of the storage housing.

[0042] In some embodiments, such as Figure 4 and Figure 5 As shown, the second cover 2 includes a support plate 22, a first baffle 23, and a second baffle 24. The first baffle 23 is installed at the first end of the support plate 22, and the second baffle 24 is installed at the second end of the support plate 22. A first atomizing chamber 221 is formed between the inner wall of the first baffle 23 and the first end of the support plate 22, and a second atomizing chamber 231 is formed between the inner wall of the second baffle 24 and the second end of the support plate 22. The support plate 22 has an opening 222. The first end of the first atomizing chamber 221 is connected to the first end of the second atomizing chamber 231 through the opening 222. The second end of the second atomizing chamber 231 is connected to the first chamber 11, and the second end of the first atomizing chamber 221 is connected to the spray nozzle 31.

[0043] Specifically, since the atomizing position 41 of the atomizing core 4 is located inside the first chamber 11, the particulate spray from the first chamber 11 will enter the second atomizing chamber 231. Larger particulate sprays, due to insufficient power or their own weight, will adhere to the inner wall of the second baffle 24 and the lower end face of the support plate 22. After accumulating on the lower end face of the support plate 22 and the inner wall of the second baffle 24, the larger particulate sprays will form essential oil droplets, which will drip into the atomizing bottle for recycling. Meanwhile, smaller particulate sprays with greater power will enter the second atomizing chamber 231 and enter the first atomizing chamber 221 through the opening 222. Some of the smaller particulate sprays, due to insufficient power, will adhere to the inner wall of the first baffle 23. The particulate sprays on the inner wall of the first baffle 23 will converge and flow into the atomizing bottle through the opening 222 for recycling. The purpose of this design is to prevent large or insufficiently powered essential oil particles from flowing out of the spray nozzle 31 in large quantities. Larger particles cannot spread to a far distance due to their own weight, thus avoiding waste of essential oil.

[0044] Preferably, the support plate 22 has a circular structure, and the first baffle 23 and the second baffle 24 are both extended circumferentially along the support plate 22. Specifically, the first baffle 23 and the second baffle 24 are circular in shape, which is close to the shape of the atomizing cover 100, thereby improving the structural compactness of the second cover 2. At the same time, the support plate 22 is used to separate the second chamber 21 to form the first atomizing chamber 221 and the second atomizing chamber 231.

[0045] Preferably, the second cover 2 also has two tubes 225. One tube 225 is installed at the opening 222, and a gas-liquid channel 223 is formed inside the tube 225. The two ends of the gas-liquid channel 223 are connected to the first atomizing chamber 221 and the second atomizing chamber 231, respectively. The other tube 225 is installed on the support plate 22, and the first end of the other tube 225 is connected to the second atomizing chamber 231. The second end of the other tube 225 is closed, and a storage chamber 224 is formed inside the other tube 225. Specifically, one tube 225 is used to connect the first atomizing chamber 221 and the second atomizing chamber 231, and the other tube 225 is used to allow larger particulate spray to converge in the storage chamber 224, preventing particulate spray from converging on the support plate 22 and preventing particulate spray with higher air pressure from being blown into the first atomizing chamber 221, thereby further improving the utilization efficiency of essential oil recovery.

[0046] Preferably, the spray pipe 3 is inclined, and the inclination direction of the spray pipe 3 is opposite to that of the air intake assembly 5. Specifically, this spray pipe 3 is used to guide the particulate spray in the first atomizing chamber 221 to be sprayed out from the spray port 31. Since the air intake assembly 5 is located on the back of the atomizing cover 100, the air intake assembly 5 needs to be connected to the air intake pipe of the air pump. Therefore, the spray pipe 3 is inclined on the front of the atomizing cover 100, so that the particulate spray is sprayed out from the front of the atomizing cover 100, and the spatial arrangement of its structure is more reasonable.

[0047] This utility model also proposes an atomizer, including an atomizing bottle and an atomizing cap 100 as described above. The first cap 1 of the atomizing cap 100 is detachably installed on the atomizing bottle. When the atomizing cap 100 is applied to the atomizer, if the sealing rubber stopper 54 of the atomizer ages during long-term use, causing air leakage, the sealing rubber stopper 54 of the atomizing cap 100 can be replaced to improve the sealing of the connection between the air pump and the atomizer; this avoids insufficient air pressure in the atomizing core 4 due to air leakage, thus improving the stability of the atomizer's use.

[0048] When referencing drawings, new features are explained. To avoid redundant references to drawings that would make the description less concise, features already described will not be referenced again on the drawings if the description is clear.

The purpose is to enable the public to have a more thorough and comprehensive understanding of the disclosed content of this utility model, and it is not intended to limit the protection scope of this utility model.
