Description

Technical Field

[0001] The utility model relates to the technical field of aroma diffusers and parts thereof, in particular to an atomizer assembly and an aroma diffuser using the atomizer assembly. Background Art

[0002] Aromatherapy can not only make the environment fragrant, but also has health benefits such as calming the mind, resisting fatigue and cheering up the mood; aroma diffusers can atomize liquid aromatherapy essential oils into mist, which can float in the air and gradually diffuse into the environment, thus filling the entire environment. With the improvement of living standards, more and more places such as homes, offices and shops are equipped with aroma diffusers.

[0003] In the prior art, aroma diffusers mainly have two types of atomization mechanisms: one based on the Venturi effect and the other based on the ultrasonic atomization principle.

[0004] The Chinese utility model announcement with announcement number CN215284295U and titled "A Vehicle-mounted Aromatherapy Diffuser" records a typical structure of an aroma diffuser based on the Venturi effect, wherein the aroma diffuser elbow nozzle 25 (i.e., atomizer component) is one of its core components, and the elbow nozzle 25 includes:

[0005] The air intake column 251 is provided with an air intake hole 253 and a pressure boost hole 254 which are interconnected;

[0006] A positive pressure column 252 fixedly connected to the air inlet column 251 at one end is integrally formed in this embodiment, and a positive pressure connection hole 255 and a positive pressure oil outlet hole 257 that are interconnected are opened in the positive pressure column 252, and the positive pressure oil outlet hole 257 and the boost hole 254 are arranged at one end close to each other;

[0007] A positive pressure counter-atomizing surface 256 is provided on the boost column, and the positive pressure counter-atomizing surface 256 is provided at one end of the positive pressure oil outlet hole 257 away from the positive pressure connecting hole 255;

[0008] The counteracting inclined surface 258 is provided on a side of the positive pressure oil outlet hole 257 close to the pressurizing hole 254 .

[0009] The straw 26 extends into the essential oil bottle 21 to absorb the essential oil, and the air inlet column 251 of the positive pressure column 252 of the elbow nozzle is connected to the negative pressure device through a silicone tube. The vacuum air pressure generated by the negative pressure device causes the essential oil to be discharged through the positive pressure oil outlet hole 257. Since the hedging slope 258 and the boosting hole 254 present a certain angle, and the sizes of the boosting hole 254 and the positive pressure oil outlet hole 257 are both between 0.1-0.5mm, the gas in the boosting hole 254 can present a strong air pressure, and on the other hand, the essential oil in the positive pressure oil outlet hole 257 can be emitted in a small molecular structure. Since the essential oil itself has a certain volatility, combined with the strong air pressure of the boosting hole 254, the essential oil is atomized on the positive pressure hedging atomization surface 256 and then floats and overflows in the space formed by the nozzle lower cover 22 and the nozzle upper cover 23 to form an atomization effect.

[0010] At present, various household appliances and electronic products are gradually undergoing the process of integration and miniaturization. The above-mentioned elbow nozzle 25 (atomizer component) integrates the functions of absorbing essential oils, guiding airflow and atomizing essential oils, which is conducive to the miniaturization of aromatherapy diffusers.

[0011] However, since the boost hole 254 of the elbow nozzle 25 (atomizer component) directly sprays out high-pressure airflow, generating relatively large airflow noise, the operation noise of the aroma diffuser is relatively large, affecting the user experience.

[0012] In summary, how to provide a low-noise atomizer assembly for an aroma diffuser has become one of the problems that need to be solved urgently. Utility Model Content

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] This embodiment provides an atomizer assembly, which is based on the Venturi effect and is used to atomize aromatherapy essential oil into a mist.

[0031] See also Figure 1-Figure 3 The atomizer assembly of this embodiment includes an atomizer body component 1.

[0032] The atomizer body component 1 is a small-sized engineering plastic workpiece formed by integral injection molding.

[0033] An air flow channel 15 is formed inside the atomizer body component 1 , and air flow holes 151 communicating with the air flow channel 15 are formed on the surface of the atomizer body component 1 . In fact, the air flow channel 15 and the air flow holes 151 are integrally injection molded with the atomizer body component 1 .

[0034] An oil suction channel 16 is formed inside the atomizer body component 1 , and an essential oil injection hole 161 connected to the oil suction channel 16 is formed on the surface of the atomizer body component 1 . In fact, the oil suction channel 16 and the essential oil injection hole 161 are integrally injection molded with the atomizer body component 1 .

[0035] The airflow perforations 151 and the essential oil perforations 161 of the atomizer body component 1 have relative positions suitable for generating an atomization effect, so as to realize the basic function of atomizing the aromatherapy essential oil into a mist-like body.

[0036] In order to shield the noise generated by the atomizer assembly during operation, the atomizer assembly of this embodiment further includes a muffler ring component 2 .

[0037] It should be noted that the muffler ring component 2 can be a ring-shaped body made of metal material or a ring-shaped body made of engineering plastic material. In this embodiment, the muffler ring component 2 is a ring-shaped body made of metal material, such as stainless steel or aluminum alloy.

[0038] The silencer ring component 2 surrounds the air flow perforations 151 and the essential oil perforations 161 of the atomizer body component 1 , so that the atomization effect occurs in the inner ring of the silencer ring component 2 .

[0039] Specifically, the atomizer body component 1 is sequentially arranged along its extension direction as an atomizer mounting section 11, a top rib section 12, a silencer ring mounting section 13 and an oil suction section 14, that is, the atomizer mounting section 11, the top rib section 12, the silencer ring mounting section 13 and the oil suction section 14 are an integrated external structure formed on the atomizer body component 1; the air flow channel 15 starts from the top of the atomizer mounting section 11, passes through the atomizer mounting section 11, the top rib section 12 and the silencer ring mounting section 13 in sequence, and forms an air flow perforation 151 at the bottom of the silencer ring mounting section 13; the oil suction channel 16 starts from the bottom of the oil suction section 14, passes through the oil suction section 14, and forms an essential oil perforation 161 on the side of the oil suction section 14; the silencer ring component 2 is sleeved on the silencer ring mounting section 13 of the atomizer body component 1, and extends toward the direction of the oil suction section 14 to surround the air flow perforation 151 and the essential oil perforation 161.

[0040] Specifically, a plurality of mounting ribs 131 are formed on the surface of the silencer ring mounting section 13 of the atomizer body component 1. In the present embodiment, the mounting ribs 131 are arranged in the vertical direction, and the mounting ribs 131 are evenly distributed circumferentially along the surface of the silencer ring mounting section 13 of the atomizer body component 1. The inner wall 21 of the silencer ring component 2 is interference fit with the mounting ribs 131 of the atomizer body component 1, and the silencer ring component 2 is fixed by friction fit with the mounting ribs 131, which is relatively simple to assemble.

[0041] See also Figure 2 and Figure 3 Specifically, the central axis of the airflow channel 15, the central axis of the airflow perforation 151, the central axis of the oil suction channel 16 and the central axis of the essential oil perforation 161 are all located in the same plane.

[0042] See also Figure 2 and Figure 3 Specifically, the central axis of the airflow perforation 151 and the central axis of the essential oil perforation 161 are perpendicular to each other.

[0043] The airflow perforations 151 and the essential oil perforations 161 are arranged in the above-mentioned manner, so that the airflow perforations 151 and the essential oil perforations 161 have a relative position suitable for generating an atomization effect.

[0044] When the atomizer assembly of this embodiment is in use, the atomizer mounting section 11 of the atomizer body component 1 is plugged into the rigid air inlet pipe of the aroma diffuser to fix the entire atomizer assembly, and the oil suction pipe of the aroma diffuser is plugged into the oil suction section 14 of the atomizer body component 1, and the oil suction pipe extends into the essential oil bottle of the aroma diffuser to absorb the aromatherapy essential oil; after the air source of the aroma diffuser is started, air flow can be introduced into the rigid air inlet pipe, and the air flow enters the air flow channel 15 from the atomizer mounting section 11 of the atomizer body component 1, and is ejected from the air flow perforation 151. At this time, a Venturi effect will be formed near the air flow perforation 151 and the essential oil perforation 161, and the oil suction channel 16 absorbs the aromatherapy essential oil from the essential oil bottle through the oil suction pipe, and is atomized into a mist at the essential oil perforation 161, and the mist is guided by the internal structure of the aroma diffuser and can be diffused into the air.

[0045] In the above process, since the atomization effect occurs in the inner ring of the silencer ring component 2, the noise generated by the airflow perforations 151 when spraying airflow can be shielded in the inner ring of the silencer ring component 2, so that the atomizer assembly of this embodiment has a good silent effect during operation.

[0046] Furthermore, the oil suction section 14 of the atomizer body component 1 forms a first end surface 141 which is at an angle to the horizontal plane above the essential oil perforation 161, that is, the first end surface 141 is integrally formed on the surface of the oil suction section 14, and the angle between the first end surface 141 and the horizontal plane is an obtuse angle; the first end surface 141 can block at least a portion of the airflow perforation 151 of the atomizer body component 1, so that the airflow perforation 151 is shielded to a certain extent.

[0047] Furthermore, the oil suction section 14 of the atomizer body component 1 forms a second end face 142 at an angle to the horizontal plane on the surface of the essential oil perforation 161, that is, the second end face 142 is integrally formed on the surface of the oil suction section 14, and the angle between the second end face 142 and the horizontal plane is an acute angle; the second end face 142 is connected to the first end face 141, so that the second end face 142 and the first end face 141 together constitute an integrated protruding structure on the surface of the oil suction section 14 of the atomizer body component 1.

[0048] The first end face 141 and the second end face 142 are provided. When the airflow flows through the first end face 141 and enters the second end face 142, the flow velocity increases, making it easier to form a Venturi effect near the airflow perforation 151 and the essential oil perforation 161 of the atomizer body component 1.

[0049] See also Figure 3 Furthermore, the air flow channel 15 of the atomizer body component 1 is sequentially arranged along its axial direction as a cylindrical extension portion 152 and a conical first narrowing portion 153; the first narrowing portion 153 is connected to the air flow perforation 151, and such arrangement can effectively increase the flow velocity of the air flow at the air flow perforation 151.

[0050] See also Figure 3 Furthermore, the top of the oil suction channel 16 is narrowed along its radial direction to form a second narrowing portion 162; the second narrowing portion 162 is connected to the essential oil perforation 161, and this arrangement can effectively increase the flow rate of the aromatherapy essential oil when passing through the second narrowing portion 162.

[0051] This embodiment also provides a fragrance diffuser, which includes the above-mentioned atomizer assembly.

[0052] The atomizer assembly of the present embodiment and the aroma diffuser using the same, the silencer ring component 2 surrounds the airflow perforations 151 and the essential oil perforations 161 of the atomizer body component 1, so that the atomization effect occurs in the inner ring of the silencer ring component 2. Since the atomization effect occurs in the inner ring of the silencer ring component 2, the noise generated by the airflow perforations 151 when spraying airflow can be shielded in the inner ring of the silencer ring component 2, so that the atomizer assembly of the present embodiment has a good silent effect during operation, thereby improving the user experience of the aroma diffuser.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
