Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] Currently, spray devices are commonly used to fully disperse liquids in the air. However, existing spray devices generally produce large liquid particles, causing the liquid to float in the air for a short time before quickly falling down, resulting in insufficient dispersion and poor dispersion effect.

[0030] Based on the above problems, this utility model provides a spray device that can be applied to equipment such as aroma diffusers. The spray device can quickly and evenly disperse essential oils or fragrance liquids into the space like gas after spraying, ensuring that the fragrance quality of the essential oils or fragrance liquids is maintained during the diffusion process, and can make the scent in the space last for a long time.

[0031] Please see Figures 1 to 4 The spraying device 10 includes an air source 100, a venturi tube 200, and a liquid storage tank 300.

[0032] The venturi tube 200 is provided with an air inlet channel 210, a liquid inlet channel 220 and an injection channel 230 that are interconnected. The air inlet channel 210 is connected to the air source 100, which is used to input gas into the air inlet channel 210. The liquid inlet channel 220 is connected to the liquid storage tank 300, which is used to input liquid into the liquid inlet channel 220. The inner diameter of the air inlet channel 210 gradually decreases in the direction toward the injection channel 230.

[0033] In this embodiment, high-pressure gas is input into the air intake channel 210 through the gas source 100, and the inner diameter of the air intake channel 210 is gradually reduced to increase the flow rate of the gas flowing into the injection channel 230. This not only allows the liquid in the storage tank 300 to flow into the injection channel 230 under the action of gas pressure, but also allows the liquid flowing into the injection channel 230 to be fully mixed with the gas under the action of the gas. As a result, after being sprayed out from the opening of the injection channel 230, the liquid is fully atomized and can be evenly diffused in the air.

[0034] Furthermore, by inputting gas of different flow rates into the liquid inlet channel 220 through the gas source 100, gas-liquid mixtures with different atomization effects can be sprayed through the venturi tube 200, thereby adapting to different usage scenarios and improving the adaptability of the spray device.

[0035] In practical applications, the storage tank 300 can hold essential oils or fragrance liquids, so that after the essential oils or fragrance liquids are sprayed out through the venturi tube 200, they can quickly and fully diffuse into the air, ensuring that they maintain their fragrance quality during the diffusion process and that the scent can remain in the air for a longer period of time.

[0036] Furthermore, the intake passage 210 includes a first section 211 and a second section 212 that are connected to each other. The first section 211 is connected to the air source 100, and the second section 212 is connected to the injection passage 230. The inner diameter of the second section 212 gradually decreases in the direction toward the injection passage 230.

[0037] In this embodiment, the maximum inner diameter of the first segment 211 is the same as the inner diameter of the second segment 212. Therefore, when the gas source 100 inputs high-pressure gas into the first segment 211, it can be ensured that the gas can be input into the first segment 211 to the maximum extent, and the gas flow rate is accelerated in the second segment 212, which facilitates the removal of liquid from the storage tank 300 and the thorough mixing with the liquid to form a mist spray.

[0038] Furthermore, the intake passage 210 also includes a third section 213, one end of which is connected to the second section 212 and the other end is connected to the injection passage 230. The inner diameter of the third section 213 gradually increases in the direction toward the injection passage 230.

[0039] In this embodiment, the first segment 211, the second segment 212, and the third segment 213 are connected in sequence. After the gas reaches its fastest speed at the end of the second segment 212, it enters the flared third segment 213 to increase the flow space of the gas, so that the gas can be fully mixed with the liquid that enters the Venturi tube 200 together, ensuring that the liquid is sprayed out in a mist and evenly diffused in the air.

[0040] Specifically, the minimum inner diameter of the second segment 212 is the same as the minimum inner diameter of the third segment 213, and the minimum inner diameter segment between the third segment 213 and the second segment 212 is an extension segment. In other words, one end of the extension segment is connected to the minimum inner diameter end of the second segment 212, and the other end is connected to the minimum inner diameter end of the third segment 213.

[0041] It is understandable that the above settings enable the Venturi effect to be formed within the Venturi tube 200, thereby making the spray particles passing through the Venturi tube 200 finer.

[0042] Furthermore, the liquid inlet channel 220 is connected between the air inlet channel 210 and the injection channel 230.

[0043] In this embodiment, the air intake channel 210 and the injection channel 230 are located on the same straight line. The liquid inlet channel 220 is perpendicular to the straight line where the air intake channel 210 and the injection channel 230 are located. One end of the liquid inlet channel 220 is connected to the liquid storage tank 300, and the other end is connected between the air intake channel 210 and the injection channel 230. This allows the liquid in the liquid storage tank 300 to flow rapidly from the liquid inlet channel 220 to the injection channel 230 under the action of the high-speed gas flow channel.

[0044] Furthermore, the spraying device 10 also includes a connecting pipe 400, one end of which is connected to the air source 100 and the other end of which is connected to the venturi tube 200.

[0045] In this embodiment, the gas source 100 can be an air pump, and the air pump and the venturi tube 200 are connected by a connecting pipe 400, which can ensure that high-pressure gas is stably input into the air intake channel 210 of the venturi tube 200.

[0046] Specifically, the connecting tube 400 can be made of soft rubber material, which makes it easy to bend the connecting tube 400, thereby allowing the venturi tube 200 to be oriented in any direction and increasing the spray range of the venturi tube 200.

[0047] Furthermore, the spraying device 10 also includes a liquid guide pipe 500, one end of which is connected to the liquid inlet channel, and the other end extends into the liquid storage tank 300.

[0048] In this embodiment, one end of the liquid guide tube 500 extends into the liquid inlet channel 220 and is sealed to the liquid inlet channel 220, while the other end extends into the bottom of the liquid storage tank 300 to ensure that the liquid in the liquid storage tank 300 can be input into the liquid inlet channel more smoothly.

[0049] Furthermore, the air source 100 includes an air compressor pump, which is connected to the air intake passage 210 for inputting gas into the air intake passage 210.

[0050] In this embodiment, high-pressure gas can be input into the venturi tube 200 by an air compressor pump, thereby ensuring that the liquid in the storage tank 300 forms mist particles after being impacted by the gas in the high-speed flow channel, and is evenly diffused into the air through the spray channel 230.

[0051] In other words, by inputting gas at different flow rates into the Venturi tube 200 through an air compressor pump, gas-liquid mixtures with different atomization effects can be sprayed through the Venturi tube, thereby adapting to different usage scenarios.

[0052] Optionally, the output gas flow rate of the air compressor pump is 1.4L / min to 3.0L / min. For example, the output gas flow rate of the air compressor pump can be 1.4L / min, 1.6L / min, 1.8L / min, 2.0L / min, 2.2L / min, 2.4L / min, 2.6L / min, 2.8L / min, and 3.0L / min.

[0053] In practical applications, when the output gas flow rate of the air compressor pump is 1.4 L / min, the spray particle size is approximately 5.1 μm; when the output gas flow rate of the air compressor pump is 1.6 L / min, the spray particle size is approximately 3.6 μm; when the output gas flow rate of the air compressor pump is 2.8 L / min, the spray particle size is approximately 3.7 μm; and when the output gas flow rate of the air compressor pump is 3 L / min, the spray particle size can reach approximately 1.6 μm, which is significantly smaller than the particle size sprayed by existing spraying equipment.

[0054] Furthermore, this utility model also provides an aromatherapy diffuser, which includes the spray device 10 in the above embodiments.

[0055] In summary, this invention provides a spray device 10 and an aromatherapy diffuser. High-pressure gas is input into the air inlet channel 210 via the gas source 100, and the inner diameter of the air inlet channel 210 gradually decreases to increase the flow velocity of the gas flowing into the spray channel 230. This not only allows the liquid in the storage tank 300 to flow into the spray channel 230 under gas pressure, but also ensures that the liquid flowing into the spray channel 230 is fully mixed with the gas. Therefore, after being sprayed from the opening of the spray channel 230, the liquid is fully atomized and can be evenly diffused into the air. Furthermore, by inputting gas of different flow rates into the liquid inlet channel 220 via the gas source 100, gas-liquid mixtures with different atomization effects can be sprayed through the venturi tube 200, thus adapting to different usage scenarios.

[0056] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
