Description

Technical Field

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

[0002] With the development of the times, people's lives have been greatly improved. In order to meet the need for fresh air, people use air fresheners.

[0003] Aroma diffusers, as a common electrical appliance, primarily function by using atomization technology to transform essential oils into tiny particles, which are then evenly dispersed into the air to create a pleasant fragrance environment, enhancing the comfort and atmosphere of living or working spaces. Aroma diffusers not only improve air quality but can also regulate people's emotions through different fragrance formulas, promoting relaxation or mental alertness.

[0004] The aroma diffuser is equipped with an air pump to generate high-pressure, high-speed gas. This gas disperses liquefied essential oils, atomizing them into microparticles. It then draws in external gas, compresses it, and discharges it from the outlet, ultimately creating high-pressure, high-speed gas.

[0005] The atomized essential oil is diffused outside the fragrance diffuser through components such as the mist output component, thereby spraying the space around the fragrance diffuser.

[0006] In existing fragrance diffusers, the mist output component is generally achieved through an oil baffle. However, in existing technologies, the oil baffle structure is unreasonable, which causes the atomized essential oil particles to not be evenly distributed, resulting in poor mist output.

[0007] In addition, in existing technologies, essential oil particles disperse quickly, which generates a lot of noise when they collide with the components on the fragrance diffuser, resulting in a poor user experience.

[0008] Therefore, it is imperative for the industry to provide an improved fragrance diffuser to overcome the shortcomings of the aforementioned prior art. Utility Model Content

[0009] The purpose of this invention is to solve the above-mentioned problems and provide a fragrance diffuser.

[0010] To achieve the objectives of this utility model, the following technical solution is adopted:

[0011] An aroma diffuser includes: an essential oil bottle, an atomizing head sealed at the mouth of the essential oil bottle, an atomizing core disposed within the atomizing head and communicating with the essential oil bottle, and a mist outlet cap disposed on the top of the atomizing head. The mist outlet cap has a disc body with mist outlet grooves formed along its circumferential edge. A baffle corresponding to the mist outlet grooves is formed on the upper part of the disc body, and a mist outlet gap is formed between the end of the baffle and the corresponding end of the mist outlet grooves.

[0012] Preferably, the disc body is circumferentially provided with a plurality of mist outlet grooves and corresponding baffles. More preferably, the mist outlet cover further has a conical shape, the conical shape is formed on the disc body, and the baffle is disposed on the conical shape.

[0013] Preferably, the cone-shaped body forms a channel at its center and a flange distributed circumferentially around the channel, and a ball plug is disposed within the channel.

[0014] Preferably, the distance between the two opposing surfaces of the baffle tongue and the disc body is set to be between 1.5 and 7.5 mm; the radial depth of the mist outlet groove is set to be between 1.5 and 4 mm; the circumferential width of the mist outlet gap is 0.2 to 0.4 mm; and the axial height of the baffle is 5 to 15 mm.

[0015] Preferably, the fragrance diffuser further includes a cylinder, in which the essential oil bottle is disposed. A fan is installed on the side wall of the cylinder, which can accelerate the dispersion speed of the atomized essential oil particles, thereby quickly filling the space with fragrance. More preferably, the fragrance diffuser further includes an air pump that outputs high-pressure, high-speed gas to the atomizing core.

[0016] Preferably, the air pump is connected to the interior of the atomizing core via an air inlet pipe to deliver the required gas. More preferably, the atomizing head has a sidewall with an opening formed therein, and a shock-absorbing sleeve is provided within the opening. The shock-absorbing sleeve is connected to and communicates with the air inlet pipe, and also with the interior of the atomizing core.

[0017] Preferably, the fragrance diffuser further includes a housing, and the cylinder, atomizing head and air pump are all disposed within the housing.

[0018] This utility model further provides a fragrance diffuser, comprising: an essential oil bottle, an atomizing head tightly disposed at the mouth of the essential oil bottle, an atomizing core disposed within the atomizing head and communicating with the essential oil bottle, and a mist outlet cover disposed at the top of the atomizing head. The mist outlet cover has a disc body, a mist outlet groove is formed on the periphery of the disc body, and a baffle corresponding to the mist outlet groove is formed on the upper part of the disc body. A mist outlet gap is formed between the end of the baffle and the corresponding end of the mist outlet groove. A silencer cover is disposed above the mist outlet cover. The silencer cover has a plate body, a mist outlet is formed on the plate body, and an annular sidewall is formed at the bottom of the plate body. Multiple partitions are formed radially outward on the annular sidewall. The baffle is disposed between two adjacent partitions.

[0019] Preferably, the fog outlet cover further has a conical shape, the conical shape is formed on the disc body, and the baffle is disposed on the conical shape; a slot is opened on the annular sidewall corresponding to the two partitions; the baffle is disposed in the slot; a fog outlet channel is formed between two adjacent partitions.

[0020] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0021] In this invention, a misting gap is formed between the end of the baffle tongue and the corresponding end of the misting groove. The atomized essential oil particles first flow through the misting groove, and then, due to the flow-limiting effect of the baffle tongue, flow out along the misting gap to the top of the misting cap. The baffle tongue has a certain flow-limiting effect on the atomized essential oil airflow, preventing larger diameter essential oil particles from dispersing, while only allowing smaller diameter essential oil particles to disperse.

[0022] Furthermore, since the silencer cover has a plate body with a mist outlet, and an annular sidewall formed at the bottom of the plate body, multiple partitions are formed radially outward on the annular sidewall. The silencer cover is disposed on the mist outlet cover, and the baffle is disposed between two adjacent partitions. Therefore, the atomized essential oil particles can enter the mist outlet channel from the bottom of the mist outlet cover, and flow out into the area between two adjacent partitions due to the obstruction of the baffle, forming a mist outlet channel. Then, the mist flows upward along the annular sidewall into the mist outlet, and then diffuses into the external space from the mist outlet, achieving fragrance treatment of the indoor space, while ensuring extremely low operating noise, providing users with a quiet and comfortable user experience.

It should also be understood that terms such as those defined in general dictionaries should be understood to have the same meaning as in the context of the prior art, and should not be interpreted in an idealized or overly formal sense unless specifically defined as herein.

[0037] In one embodiment of this utility model, reference is made to Figure 1-5A fragrance diffuser 100 is provided, comprising: an essential oil bottle 10, an atomizing head 30 tightly disposed at the mouth of the essential oil bottle 10, an atomizing core 20 disposed within the atomizing head 30 and communicating with the essential oil bottle 10, and a mist outlet cap 40 disposed at the top of the atomizing head 30.

[0038] In the above embodiment, the essential oil bottle 10 contains essential oils. The essential oils can be essential oils with various formulas and scents, such as plant essential oils extracted from various plants, so that the essential oils can have various different scents. At the same time, the essential oils can have different viscosities and volatility, so that they can be adapted to different occasions and people.

[0039] The essential oil in the essential oil bottle 10 is drawn into the atomizing core 20 through its internal tubing (not shown). Then, the air pump 90 pumps high-pressure, high-speed gas into the atomizing core 20 through the air inlet pipe 92, causing the high-pressure, high-speed gas to blow the essential oil that enters the atomizing core 20 into particles, which are then dispersed to the outside through the mist outlet cap 40.

[0040] Here, the essential oil bottle 10 and the atomizing head 30 can be independent components, and then the two are sealed together by means such as threads or snaps. Alternatively, they can be integrally molded components to achieve a better seal.

[0041] Similarly, in the embodiments of this utility model, the atomizing core can be of various types. For example, it can be distinguished according to the direction of mist output, such as horizontal mist output type or vertical mist output type atomizing core. According to the mist output principle, it can be further distinguished as an ultrasonic vibration mist output atomizing core or a traditional air pump driven atomizing core. This utility model does not limit this.

[0042] In the above embodiments, the misting cover 40 has a crucial impact on the misting effect of the entire fragrance diffuser 100, directly affecting the uniformity, speed and noise of the misting.

[0043] Specifically, in one embodiment, such as Figures 3a-3b As shown, the mist outlet cover 40 has a disc body 42, with mist outlet grooves 422 formed on the circumferential edge of the disc body 42. A baffle tongue 44 corresponding to the mist outlet grooves 422 is formed on the upper part of the disc body 42, and a mist outlet gap 46 is formed between the end of the baffle tongue 44 and the corresponding end of the mist outlet groove 422. The atomized essential oil particles formed in the atomizing head 30 first flow through the mist outlet grooves 422, and then, due to the flow restriction effect of the baffle tongue 44, flow out along the mist outlet gap 46 between the two ends of the baffle tongue 44 and the mist outlet grooves 422 to the top of the mist outlet cover 40. Then, through an air outlet 70 provided on the top of the mist outlet cover 40, the atomized essential oil particles are further diffused into the surrounding environment, ultimately filling the surrounding environment with fragrance in a short period of time.

[0044] In this embodiment, the baffle 44 has a certain obstruction and flow-limiting effect on the atomized essential oil airflow, preventing larger diameter essential oil particles from dispersing and only allowing smaller diameter essential oil particles to disperse. In addition, the mist outlet gap 46 can guide the essential oil airflow to disperse along a specific location, thereby improving the flexibility of the fragrance diffuser.

[0045] To achieve a more uniform mist effect, preferably, the disc body 42 is circumferentially provided with a plurality of mist outlet grooves 422 and corresponding baffles 44. For example, in one embodiment, four mist outlet grooves 422 can be formed on the disc body 42, and similarly, four corresponding baffles 44 can be provided, thereby forming eight circumferentially evenly distributed mist outlet gaps 46. This allows the atomized essential oil airflow to be dispersed along the eight evenly distributed mist outlet gaps 46, thereby improving the mist effect.

[0046] Preferably, in one embodiment, the fog outlet cover 40 further has a cone-shaped body 48 formed on the disc body 42, and the baffle 44 is disposed on the cone-shaped body 48. The cone-shaped body 48 has the effect of strengthening the overall structural strength of the fog outlet cover 40, and since the baffle 44 is formed on the cone-shaped body 48, the manufacturing difficulty of the entire fog outlet cover 40 is reduced.

[0047] Preferably, the cone 48 forms a channel 43 at its center and a retaining flange 45 distributed circumferentially around the channel 43, and a ball plug 50 is disposed within the channel 43. When the fragrance diffuser 100 is not placed correctly, such as when the fragrance diffuser 100 is placed at a severe tilt or even upside down, the ball plug 50 blocks the channel 43, thereby delaying the leakage of essential oils.

[0048] Preferably, in order to obtain a better filtering or blocking effect for essential oil particles, allowing smaller diameter essential oil particles to escape while blocking relatively larger diameter essential oil particles from escaping, the mist outlet cap 40 can be structurally designed as follows:

[0049] The distance between the two opposing surfaces of the tongue 44 and the disc 42 is set to be between 1.5-7.5 mm, preferably between 4.2-4.8 mm; the radial depth of the mist outlet groove 422 is set to 1.5-4 mm; the circumferential width of the mist outlet gap 46 is set to 0.2-0.4 mm; and the axial height of the flange 45 is set to 5-15 mm.

[0050] In one embodiment, the aroma diffuser 100 further includes a cylindrical body 200, within which the essential oil bottle 10 is disposed. The cylindrical body 200 protects the essential oil bottle 10 from external impacts that could cause it to break or detach from the atomizing head 30, thus damaging the entire aroma diffuser and rendering it unusable. The cylindrical body 200 can be made of, for example, plastic to reduce the overall weight of the aroma diffuser, making its structure compact and portable. Alternatively, for structural rigidity, it can be made of, for example, metal materials such as aluminum alloy or stainless steel. This invention does not limit this choice.

[0051] Furthermore, preferably, a fan 702 is provided on the side wall of the cylinder 200 to further disperse the atomized essential oil in the atomizing head 30. Through the rapid airflow effect of the fan 702, the atomized essential oil emitted from the mist outlet 40 can be quickly diffused into the surrounding environment, thereby quickly adjusting the surrounding air quality.

[0052] Fan 702 can be any type of fan, such as a DC fan or an AC fan, and can be a traditional bladed fan or a bladeless fan. Fan 702 can also be a silent fan to reduce noise during operation, thereby realizing a silent fragrance diffuser.

[0053] In one embodiment, the fragrance diffuser 100 further includes an air pump 90 that outputs high-pressure, high-speed gas to the atomizing core 20.

[0054] Furthermore, the air pump 90 is internally connected to the atomizing core 20 via the air inlet pipe 92 to deliver the required gas. When the fragrance diffuser 100 is operating, the air pump 90 vibrates, which in turn causes noise. To reduce or even avoid vibration, the connection structure between the air inlet pipe 92 and the atomizing core 20 can be improved.

[0055] Specifically, the atomizing head 30 has a side wall 32, on which an opening 322 is formed. A shock-absorbing sleeve 80 is provided inside the opening 322. The shock-absorbing sleeve 80 is connected and communicates with the air inlet pipe 92 and also communicates with the interior of the atomizing core 20.

[0056] The shock-absorbing sleeve 80 can be made of materials such as rubber, making it not only soft but also elastic. This allows the sleeve to create a seal between the air intake pipe 92 and the atomizing core 20, preventing gas leakage and thus reducing the atomization effect of the essential oil. Simultaneously, the sleeve's elasticity helps absorb vibrations, providing a damping effect.

[0057] Preferably, the fragrance diffuser 100 further includes a housing 94, in which the cylinder 200, atomizing head 30 and air pump 90 are all disposed, so as to enclose the above-mentioned components and play a protective role. At the same time, the housing 94 also has an aesthetic function.

[0058] Also refer to Figure 6-8 According to another embodiment of this utility model, a similar mist outlet cover 200 may also have a disc body 202, such as a circular disc body 202; in addition, a mist outlet groove 2022 is formed on the periphery of the disc body 202, and a baffle tongue 204 corresponding to the mist outlet groove 2022 is formed on the upper part of the disc body 202, and a mist outlet gap 206 is formed between the end of the baffle tongue 204 and the corresponding end of the mist outlet groove 2022. The atomized essential oil particles formed in the atomizing head 30 first flow through the mist outlet groove 2022, and then flow out along the mist outlet gap 206 between the two ends of the baffle tongue 204 and the mist outlet groove 2022 to the top of the mist outlet cover 200 due to the flow restriction effect of the baffle tongue 204, and then further diffuse the atomized essential oil particles into the surrounding environment through, for example, an air outlet 70 provided on the top of the mist outlet cover 200, so that the surrounding environment is filled with fragrance in a short period of time.

[0059] In this embodiment, the baffle 204 has a certain obstruction and flow-limiting effect on the atomized essential oil airflow, preventing larger diameter essential oil particles from dispersing and only allowing smaller diameter essential oil particles to disperse. Furthermore, the mist outlet gap 206 can guide the essential oil airflow to disperse along specific locations, thereby improving the flexibility of the fragrance diffuser.

[0060] Preferably, in one embodiment, the fog outlet cover 200 further has a cone-shaped body 208 formed on the disc body 202, and the baffle 204 is disposed on the cone-shaped body 208. The cone-shaped body 208 has the effect of strengthening the overall structural strength of the fog outlet cover 200, and since the baffle 204 is formed on the cone-shaped body 208, the manufacturing difficulty of the entire fog outlet cover 200 is reduced.

[0061] Furthermore, it should be noted that a silencer cover 300 is provided above the mist outlet cover 200 to reduce the impact force of the atomized essential oil particles during their dispersion, thereby reducing the noise generated by the impact. Here, the silencer cover 300 has a plate body 301 with a mist outlet 304. An annular sidewall 302 is formed at the bottom of the plate body 301, and multiple partitions 3022 are formed radially outward on the annular sidewall 302. The silencer cover 300 is disposed on the mist outlet cover 200, and the tongue 204 is disposed between two adjacent partitions 3022. The atomized essential oil particles enter the mist outlet 2022 from the bottom of the mist outlet cover 200. Blocked by the baffle tongue 204, the flow direction is changed, meaning the atomized essential oil particles flow laterally out of the mist outlet gap 206 into the area between two adjacent partitions 3022. This area defines the mist outlet channel 600 for the atomized essential oil to flow through. The atomized essential oil then flows upwards along the annular sidewall 302 into the mist outlet 304, and subsequently diffuses from the mist outlet 304 to the outside of the entire fragrance diffuser, achieving fragrance treatment of the indoor space while ensuring extremely low operating noise, providing users with a quiet and comfortable experience.

[0062] Preferably, a slot 309 is formed on the annular sidewall 302 corresponding to the two partitions 3022; the tongue 204 is disposed within the slot 309. In other words, when the mist outlet cover 200 and the muffler cover 300 are assembled vertically, the slot 309 restricts the tongue 204 in the left and right directions, thus positioning the mist outlet cover 200 and the muffler cover 300 in a mutually positioning assembly, preventing relative rotation between them, and ensuring the stability of the assembly.

[0063] Those skilled in the art will understand that the steps, measures, and solutions in the various operations, methods, and processes discussed in this application can be alternated, modified, combined, or deleted. Furthermore, other steps, measures, and solutions in the various operations, methods, and processes discussed in this application can also be alternated, modified, rearranged, decomposed, combined, or deleted. Furthermore, steps, measures, and solutions in the prior art that are similar to those disclosed in this application can also be alternated, modified, rearranged, decomposed, combined, or deleted.

[0064] The above description is only a partial embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
