Description

Technical Field

[0001] This utility model relates to the field of aroma diffuser technology, specifically to an aroma diffuser. Background Technology

[0002] As living standards continue to improve, more and more people are paying more attention to their quality of life. People not only need beautiful and clean living and working environments, but also clean, odor-free air. Based on this, diffusers were invented. These devices atomize perfumes or essential oils, diffusing the fragrance into the air to improve air quality. In existing diffusers, an air pump provides airflow to the atomizing head. The atomizing head creates negative pressure under the action of the airflow, using the siphon principle to draw essential oils from the essential oil bottle through a suction tube. The airflow is then mixed with the essential oils and atomized to form a fragrant mist.

[0003] Existing aroma diffusers typically feature an air intake channel in the atomizing head. One end of this channel connects to an air pump via a pipe, while the other end connects to the atomizing head, guiding the airflow generated by the air pump into the atomizing head (see patent application number 201420440948.4). The atomizing head is usually fixed to the diffuser's housing. When the essential oil bottle needs to be replaced, it can be unscrewed. To facilitate bottle replacement, the wash tubing connector is designed to be rotatable. However, the atomizing head is a crucial component of the diffuser, and its easy damage can prevent atomization. Disassembling and reconnecting the atomizing head to the housing can affect the stability of the connection, leading to an unstable airflow channel and potential leaks. Utility Model Content

Detailed Implementation

[0026] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand this utility model and implement it. However, the embodiments are not intended to limit this utility model. In this embodiment, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this utility model.

[0027] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to and integrated with the other element, or there may be an intervening element present. The terms "mounted," "one end," "the other end," and similar expressions used in this invention are for illustrative purposes only.

[0028] Please refer to Figures 1 to 8 This utility model provides a diffuser device, including a mounting base 1, an atomizing mechanism, and an air pump mechanism. The atomizing mechanism includes an atomizing head 22 and an essential oil bottle 21. The atomizing head 22 is connected to the essential oil bottle 21 via a suction tube. The atomizing head 22 is detachably mounted on the mounting base 1. The air pump mechanism includes an air pump 31 and an air delivery pipe 32 connected to each other. The mounting base 1 has a mounting groove 11, which has a mounting opening and a connecting nozzle 111. The mounting opening 112 is opposite to the connecting nozzle 111. The end of the air delivery pipe 32 away from the air pump passes through the connecting nozzle 111 and extends into the mounting groove 11, and is confined within the mounting groove 11. The atomizing head 22 is detachably mounted in the mounting groove 11. The atomizing head 22 has an air inlet pipe 221. When the atomizing head 22 is mounted in the mounting groove 11 through the mounting opening 112, at least a portion of the air inlet pipe 221 is inserted into the air delivery pipe 32 located in the mounting groove 11. When the aroma diffuser is working, the air pump provides a high-speed airflow to the atomizing head 22, creating a negative pressure. Due to the negative pressure, the essential oil in the essential oil bottle 21 is gradually drawn into the atomizing head 22, and the high-speed airflow provided by the air pump atomizes the essential oil and forms a fragrant mist.

[0029] The aroma diffuser provided by this utility model features a detachable atomizing head 22, while ensuring a stable air supply effect after installation. During installation, the atomizing head 22 and the essential oil bottle 21 are first installed together (or the atomizing head 22 can be installed on the mounting base 1 first, followed by connecting the essential oil bottle 21). Then, the atomizing head 22 with the essential oil bottle 21 is installed on the mounting base 1, and the atomizing head 22 is inserted into the mounting groove 11 through the installation opening. At this time, the air inlet pipe 221 of the atomizing head 22 is inserted into the air delivery pipe 32 located in the mounting groove 11, thus connecting the air inlet channel of the atomizing head 22 with the air delivery pipe 32. By positioning the mounting base 1, the air inlet pipe 221 of the atomizing head 22 can be smoothly and quickly connected and fixed with the air delivery pipe 32 when the atomizing head 22 is installed. By directly inserting the air inlet pipe 221 of the atomizing head 22 into the air delivery pipe 32 located in the mounting groove 11, the air delivery of the entire air delivery channel is stable after the atomizing head 22 is installed, which effectively avoids air leakage and makes the air supply of the aroma diffuser stable without affecting the atomization effect.

[0030] refer to Figure 4-8 In a preferred embodiment, the air supply pipe 32 includes a main body 321 and an air outlet 322. The air outlet 322 is the end away from the air pump 31. The main body 321 is located outside the mounting groove 11 and connected to the air pump 31. At least a portion of the air outlet 322 extends into the mounting groove 11 and is confined within the mounting groove 11, so that the air outlet of the air outlet 322 is located within the mounting groove 11 (see [link]). Figure 5 and Figure 8 When the atomizing head 22 is installed on the mounting base 1, at least a portion of the air inlet pipe 221 is inserted into the air outlet 322 through the air outlet. When at least a portion of the air inlet pipe 221 is inserted into the air outlet 322, the air inlet pipe 221 protrudes through the connecting nozzle 111, and the air outlet 322 is wrapped around the air inlet pipe 221. The retaining plate 1111 of the connecting nozzle 111 abuts against the retaining groove of the air outlet 322. (See...) Figure 7-8 At the snap-fit ​​groove, the air inlet pipe 221, the air delivery pipe 32, and the clamping plate 1111 are arranged sequentially from the inside to the outside. When the air inlet pipe 221 is inserted into the air delivery pipe 32, it squeezes the air delivery pipe 32 from the inside to the outside. The squeezed air delivery pipe 32 squeezes the external connecting nozzle 111, resulting in good tightness of the entire air delivery channel. In this embodiment, "outside the air inlet pipe 221" refers to the outside of the pipe wall, not the inner cavity of the air inlet pipe. Figure 7 As shown.

[0031] refer to Figure 6-8In a preferred embodiment, the outlet end 322 of the air supply pipe 32 is a flexible hose or the outlet end 322 of the air supply pipe 32 is elastic. Alternatively, the entire air supply pipe 32 can be a flexible hose or be elastic. When at least a portion of the air inlet pipe 221 is inserted into the outlet end 322 of the air supply pipe 32, the air inlet pipe 221 expands the air supply pipe 32 from the inside, and the outlet end 322 tightly wraps around the air inlet pipe 221. The air supply pipe 32 and the air inlet pipe 221 are tightly fitted together, and the air supply pipe 32, which is subjected to outward compression, is further pushed against by the external connecting nozzle 111. This ensures that after the atomizing head 22 is installed, the entire air supply channel has good tightness and avoids air leakage.

[0032] refer to Figure 7-8 In a preferred embodiment, the air supply pipe 32 has a first channel 32a, a second channel 32b, and a third channel 32c connected in sequence. The opening of the first channel 32a (that is, the air outlet of the air outlet 322) is located in and connected to the mounting groove 11. Part of the second channel 32b is located in the mounting groove 11, and the other part extends out of the connecting nozzle 111 and connects to the third channel 32c. The third channel 32c is located outside the mounting groove 11 and is connected to the air pump 31. The width (diameter) of the first channel 32a is greater than the width of the second channel 32b, the width of the second channel 32b is greater than the width of the third channel 32c, and the width of the first channel 32a is greater than the width (overall diameter of the air inlet pipe) of the air inlet pipe 221. The air inlet pipe 221 is inserted into the second channel 32b through the opening of the first channel 32a. The width of the channel referred to in this utility model is the diameter of the channel. In a further preferred embodiment, the first channel 32a and the second channel 32b are located at the outlet end 322 of the gas supply pipe 32, and the third channel 32c is located in the main body 321.

[0033] In this invention, the intake pipe 221 is inserted into the second channel 32b and the second channel 32b is opened, so that the air supply pipe 32 at the second channel 32b tightly wraps around the intake pipe 221, which can effectively prevent air leakage. In this embodiment, the width of the first channel 32a is greater than the width of the intake pipe 221, and the width of the first channel 32a decreases gradually from the opening away from the opening. That is, the diameter of the first channel 32a is the largest at the opening and becomes smaller as it gets closer to the second channel 32b. This allows the first channel 32a to have a guiding and positioning function, and the intake pipe 221 can be easily inserted into the air supply pipe 32 by the guidance of the first channel 32a, allowing the intake pipe 221 and the air supply pipe 32 to quickly fit together.

[0034] refer to Figure 7-8In a preferred embodiment, a limiting step 323 is provided between the second channel 32b and the third channel 32c. By setting the limiting step 323, the air intake pipe 221 can be limited and will not be inserted into the third channel 32c, but will be limited to the second channel 32b. The width (diameter) of the inner cavity of the air intake pipe 221 is less than or equal to the width (diameter) of the third channel 32b. After the air intake pipe 221 is inserted into the air delivery pipe 32, the inner cavity of the air intake pipe 221 and the third channel 32b are well connected and have a better air delivery effect, which can avoid air leakage.

[0035] refer to Figure 7-8 In a preferred embodiment, the end of the air supply pipe 32 away from the air pump includes a snap-fit ​​groove 3223, and the connecting nozzle 111 has a snap-fit ​​plate 1111. The snap-fit ​​plate 1111 of the connecting nozzle 111 snaps into the snap-fit ​​groove 3223, so that the air supply pipe 32 can be fixed on the mounting base 1. When at least a portion of the air inlet pipe 221 is inserted into the air supply pipe 32, the air inlet pipe 221 passes through the connecting nozzle 111, so that the snap-fit ​​groove 3223 of the air supply pipe partially surrounds the outside of the air inlet pipe 221, and the snap-fit ​​plate 1111 surrounds the outside of the snap-fit ​​groove 3223. When the air inlet pipe 221 is inserted into the air delivery pipe 32 through the air outlet of the air delivery pipe 32, the air inlet pipe 221 squeezes the air delivery pipe 32 from the inside out, which squeezes the snap-fit ​​groove 3223 surrounding the air inlet pipe 221, and further squeezes the snap-fit ​​plate 1111 surrounding the snap-fit ​​groove, making the connection between the air inlet pipe 221, the air delivery pipe 32 and the mounting base 1 tighter, avoiding the air delivery pipe 32 from being disconnected due to excessive air pressure from the air pump, and preventing air leakage.

[0036] refer to Figure 7-8 In a preferred embodiment, the end of the gas delivery pipe 32 furthest from the air pump has an outwardly protruding first retaining ring 3221 and a second retaining ring 3222. The first retaining ring 3221 and the second retaining ring 3222 are spaced apart, and a locking groove 3223 is formed between the first retaining ring 3221 and the second retaining ring 3222. The locking plate 1111 of the connecting nozzle 111 is inserted into the locking groove 3223 between the first retaining ring 3221 and the second retaining ring 3222. The first retaining ring 3221 is located inside the mounting groove 11, and the second retaining ring 3222 is located outside the mounting groove 11. The cooperation of the two retaining rings and the locking plate allows the gas delivery pipe 32 to be better fixed on the mounting base 1, preventing the gas delivery pipe 32 from detaching due to excessive air pressure from the air pump and preventing air leakage. In this embodiment, the first retaining ring 3221, the second retaining ring 3222, and the locking groove 3223 are all located at the air outlet 322, and the locking groove is located outside the second channel 32b.

[0037] refer to Figure 1-2In a preferred embodiment, the aroma diffuser includes a housing 4 with an installation cavity inside. The mounting base 1, the atomizing mechanism, and the air pump mechanism are all located within the installation cavity of the housing 4. The housing also has a mist outlet 43, through which the mist atomized by the atomizing head is discharged. The housing 4 includes a main body 31 and a cover 42. The mounting base 1 is connected to the main body 41. One end of the cover 42 is hinged to the main body 41, and the other end is closable from the main body 41. The cover 42 is located near the atomizing mechanism and can open or close the mounting groove 11. The term "closed" in this invention does not mean that the mounting groove 11 is completely sealed, but rather that the opening of the mounting groove 11 is not exposed. When it is necessary to disassemble the atomizing head 22, open the cover 42 to expose the opening of the mounting slot 11, pull out the atomizing head 22, and the atomizing head 22 will be taken out together with the essential oil bottle 21. It will not be restricted by the housing 4, and the essential oil bottle 21 can be easily replaced, as can the atomizing head 22.

[0038] refer to Figure 2 and Figure 7 In the preferred embodiment, when the cover 42 closes the mounting slot 11, the cover 42 abuts against the end 22a of the atomizing head 22 away from the air supply pipe 32, providing a good limiting effect on the atomizing head 22 installed in the mounting slot 11 and preventing the atomizing head 22 from loosening. In this utility model, the cover abuts and presses the atomizing head 22, so that the atomizing head 22 exerts a force on the air supply pipe 32 in the direction of the air supply pipe 32. Combined with the two retaining ring structures of the air supply pipe 32, it can prevent the pipe from dislodging due to unstable air pressure when the air pump is turned on and off, making the air supply stability of the entire aroma diffuser better and the aroma diffuser effect better.
