Description

Technical Field

[0001] The utility model relates to the technical field of atomization equipment, in particular to a temperature reduction and noise reduction device for an electric heating atomizer. Background Art

[0002] Mist-emitting devices such as humidifiers, atomizers and aromatherapy machines play an important role in modern life. Humidifiers regulate indoor humidity, improve air quality and relieve discomfort caused by dry environments by releasing water mist; atomizers use technologies such as ultrasound or compressed gas to atomize liquid medicine into tiny particles for patients to inhale and treat respiratory diseases. Aromatherapy machines create a pleasant atmosphere and soothe the body and mind by releasing essential oils. These devices all use advanced atomization technology to convert liquid water or essential oils into tiny mist particles so that they can be better diffused into the air.

[0003] Atomization is generally carried out by means of pressure, heating, sound waves, turntables, etc. In our daily life, we are mostly exposed to pressure atomization, heating atomization and ultrasonic atomization. Various atomization methods have their own advantages and disadvantages. Ultrasonic atomizers use electronic high-frequency oscillations to cause high-frequency resonance of ceramic atomizers to produce ultrasonic waves, but the oscillations will produce a lot of noise. High-temperature atomization is to heat water, and the water is converted into steam after boiling. Boiling water will also produce a lot of noise, and the temperature of the steam just converted is high, especially at the mist outlet, the temperature is close to 100°C, and it is easy to cause burns if the user approaches it carelessly. For example, the patent with announcement number CN220205955U provides an anti-scalding humidifier. The solution introduces a blower to introduce normal temperature airflow to cool the water mist, but the humidifier introduces more modules, units, and pipelines for the anti-scalding effect. The structure is relatively complex, and it is difficult to upgrade and optimize the existing common humidifiers and atomizers on the market, and there is no improvement on the noise reduction function.

[0004] Therefore, there is an urgent need to provide a temperature reduction and noise reduction device for an electric heating atomizer to solve the above technical problems. Summary of the invention

[0005] In view of the problems in the related technology, the utility model proposes a temperature reduction and noise reduction device for an electric thermal atomizer, which can achieve noise reduction processing for the electric thermal atomizer and temperature reduction processing for the mist output.

[0048] 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 of 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.

[0049] like Figures 1 to 3 As shown, this embodiment provides a cooling and noise reduction device for an electrothermal atomizer, wherein the electrothermal atomizer is provided with an atomizing chamber; the device comprises a shell, wherein the shell comprises an inner shell; the inner shell penetrates the guide chamber 1 in the upward and downward directions; an outer shell 6 is sleeved on the circumference of the inner shell, and an annular gap is provided between the two to form an isolation chamber 2 surrounding the guide chamber 1; in this embodiment, an air inlet 21 is also provided on the side wall of the outer shell 6;

[0050] In this embodiment, a plurality of partitions 11 are provided in the flow guide cavity 1. The partitions 11 are arranged horizontally and are evenly distributed in the vertical direction, including a first partition 11 and a second partition 11.

[0051] The outer peripheral edge of the first partition plate 11 is connected to the inner peripheral side wall of the guide cavity 1, that is, the inner peripheral side wall of the inner shell, and a communication port 113 is provided in the middle of the first partition plate 11;

[0052] The radial dimension of the second partition 11 is smaller than that of the first partition 11, and a connecting ring 114 is formed between the outer peripheral edge of the second partition 11 and the inner peripheral side wall of the guide cavity 1; in the present embodiment, a fixed column 13 is provided in the guide cavity 1; the fixed column 13 is vertically arranged and located in the center of the guide cavity 1; the fixed column 13 passes through the connecting port 113 and the center of the second partition 11, and is fixedly connected to the second partition 11.

[0053] The first partition plate 11 and the second partition plate 11 are arranged alternately to form a multi-layer partition 12 separated from each other from bottom to top in the guide cavity 1; a guide channel is formed along a plurality of adjacent communication openings 113 and communication ring openings 114.

[0054] The first baffles 11 and the second baffles 11 of different sizes and staggered arrangement can extend the length of the guide channel, slow down the mist outlet speed, and further improve the cooling effect of the mist / steam in the guide channel.

[0055] In this embodiment, the partition 11 is in a concave shape; the communication port 113 is arranged at the lowest position of the first partition 11; the fixed column 13 passes through the second partition 11 at the lowest position, and the lowest position of the second partition 11 is provided with a drainage hole 115 on the peripheral side of the fixed column 13; the top end surface of the guide cavity 1 is in a concave shape, and the top end surface of the guide cavity 1 is provided with a plurality of strip-shaped mist outlets 14 on the peripheral side area at the lowest position; the guide cavity 1 is connected with the outside through the mist outlet 14;

[0056] The bottom of the flow guiding chamber 1 is also provided with a mist inlet 15; the flow guiding chamber 1 is connected to the atomizing chamber through the mist inlet 15. In this embodiment, the inner bottom of the flow guiding chamber 1 is a concave surface; the mist inlet 15 is located at the lowest position of the inner bottom of the flow guiding chamber 1.

[0057] The steam / mist will generate some condensed water during the cooling process, and the condensed water will gather to form accumulated water; the top of the guide chamber 1 and the partition 11 are set to be concave, so that the accumulated water can flow downward through the mist outlet 14, or the drainage outlet, or the connecting port 113, or the mist inlet 15, and finally flow back to the atomization chamber for reuse.

[0058] The bottom of the guide cavity 1 is a concave surface, which, in addition to collecting the accumulated water, guides and drives the mist / steam to form a spiral upward airflow under the joint action of the air blown in by the air inlet channel 3.

The horizontally arranged portion of the air inlet channel 3 allows the air to be blown sideways, thereby reducing the influence on the vertical displacement of the mist / steam.

[0061] Since the mass of mist is lighter than air, it naturally rises and diffuses after being generated, and flows along the guide channel to the outside.

[0062] On the other hand, the mist gradually cools down when flowing between the multiple interlayers 12; the temperature of the mist output can be reduced to about 50°C, which will basically not cause scalding or burning to the human body;

[0063] In addition, the isolation chamber 2 isolates the flow guiding chamber 1 and the mist vapor that is cooling down in the flow guiding chamber 1, preventing the user from contacting the high-temperature mist vapor. At the same time, the device is installed at the connection with the atomizing chamber, and the isolation chamber 2 can further weaken the noise generated by the electric heating atomizer during atomization. Finally, the overall effect of cooling and noise reduction is achieved.

[0064] In this embodiment, the outer bottom of the device is provided with an annular limiting groove 16; the electric atomizer is provided with an annular limiting convex strip that matches the limiting groove 16.
