Description

Technical Field

[0001] The invention relates to a spray device, in particular to a noise reduction spray device with an audio function. Background Art

[0002] Existing spray equipment, such as humidifiers, aromatherapy machines, etc., usually use an ultrasonic generator to atomize the liquid, and then blow out the atomized gas through a fan. This type of product usually installs the fan at the bottom of the base, directly intakes air through the air inlet under the base, and then passes it into the atomization mechanism. The noise value of this type of product is around 30-38dB, and the above noise value is still relatively large when used in a relatively quiet room. For products such as household aromatherapy machines, buyers generally have high requirements for household quality. For example, playing soothing music through an aromatherapy machine with an audio function, and then meditating, etc., the environmental noise has a greater impact on the user. Therefore, it is necessary to control the noise of the spray equipment to meet the needs of more application scenarios. Summary of the invention

[0003] In order to solve the technical problem of high noise in existing spray equipment, the embodiment of the present invention provides a noise reduction spray equipment with an audio function, which can reduce the noise generated by the equipment and improve the user experience.

[0004] In order to solve the above technical problems, an embodiment of the present invention provides a noise reduction spray device with audio function, including a base, a speaker, a speaker sound cavity shell, a fan, a partition plate and an atomization assembly; the speaker is arranged in the speaker sound cavity shell, the speaker sound cavity shell is arranged in the base, and the atomization assembly is arranged above the base; the atomization assembly and the base are separated by the partition plate; the speaker sound cavity shell is provided with a fan accommodating groove recessed into the interior of its sound cavity, and the fan is arranged in the fan accommodating groove; the partition plate is provided with an air outlet interface, the air outlet of the fan is connected to the air outlet interface, and the base is provided with an air inlet; the fan drives air to enter from the air inlet, pass through the gap between the speaker sound cavity shell and the partition plate, enter the fan accommodating groove, and after passing through the fan, blow out from the air outlet interface of the partition plate, enter the atomization assembly, and blow out the mist generated by the atomization assembly.

[0005] As an improvement of the above-mentioned scheme, the atomization assembly includes a water tank, an upper cover and an atomizer, the water tank includes a water tank body and a water tank support portion, the upper cover includes an inner cover body and an outer cover body, the inner cover body is arranged in cooperation with the water tank body, and the outer cover body is arranged in cooperation with the water tank support portion.

[0006] As an improvement of the above scheme, the water tank support portion is provided with a first air outlet hole, and the inner cover body is provided with a second air outlet hole; the first air outlet hole, the gap between the inner cover body and the outer cover body, and the second air outlet hole constitute an upper air outlet channel.

[0007] As an improvement of the above scheme, the partition plate is also provided with a downwardly recessed wind pressure chamber, the water tank support portion is provided with a pressurized chamber with a gradually decreasing cross-section corresponding to the wind pressure chamber, and the top of the pressurized chamber is provided with the first air outlet.

[0008] As an improvement of the above solution, the lower end of the pressurized chamber extends into the wind pressure chamber, and the wind pressure chamber is connected to the air outlet through the space between the partition plate and the water tank body.

[0009] As an improvement on the above scheme, a first air inlet plane is provided on the upper part of the speaker sound cavity shell, and the partition plate is provided with a second air inlet plane balanced with the first air inlet plane and at a predetermined distance, and an air inlet gap is formed between the first air inlet plane and the second air inlet plane.

[0010] As an improvement of the above solution, an atomization control plate is provided in the space between the partition plate and the water tank body, and the air outlet is arranged opposite to the atomization control plate.

[0013] The implementation of the embodiments of the present invention has the following beneficial effects:

[0014] In this solution, the fan is arranged in the fan receiving slot of the speaker sound cavity shell. The fan drives the air to enter from the air inlet, pass through the gap between the speaker sound cavity shell and the partition plate, and enter the fan receiving slot. After passing through the fan, the air is blown out from the air outlet interface of the partition plate, enter the atomization assembly, and blow out the mist generated by the atomization assembly. The air inlet channel of the fan is composed of a relatively narrow channel formed by the gap between the speaker sound cavity shell and the partition plate, which can prevent the noise generated by the fan from being directly transmitted from the air inlet to the outside world, thereby achieving a noise reduction effect. After testing, the noise value of the spray equipment using the above structure can be reduced to below 25dB.

[0015] In addition, this solution hides the fan in the speaker sound cavity shell. When the speaker is working, the speaker sound cavity shell will vibrate along with the sound waves generated by the speaker. The vibration of the speaker sound cavity shell and the vibration of the fan offset each other, which can prevent the fan noise from forming the background noise of the environment, reduce interference with the sound emitted by the speaker, and make the sound effect purer and more transparent.

[0021] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0022] like Figure 1-Figure 4 As shown, a specific embodiment of the present invention provides a noise reduction spray device with audio function, including a base 1, a speaker 2, a speaker sound cavity shell 3, a fan 4, a partition plate 5 and an atomizer assembly 6; the speaker 2 is arranged in the speaker sound cavity shell 3, the speaker sound cavity shell 3 is arranged in the base 1, and the atomizer assembly 6 is arranged above the base 1; the atomizer assembly 6 and the base 1 are separated by the partition plate 5; the speaker sound cavity shell 3 is provided with a fan accommodating groove 31 recessed into the interior of its sound cavity, and the fan 4 is arranged in the fan accommodating groove 31; the partition plate 5 is provided with an air outlet interface 51, the air outlet 41 of the fan 4 is connected to the air outlet interface 51, and the base 1 is provided with an air inlet 11; the fan 4 drives air to enter from the air inlet 11, pass through the gap between the speaker sound cavity shell 3 and the partition plate 5, enter the fan accommodating groove 31, and after passing through the fan 4, blow out from the air outlet interface 51 of the partition plate 5, enter the atomizer assembly 6, and blow out the mist generated by the atomizer assembly 6.

[0023] In this solution, the fan 4 is arranged in the fan receiving slot 31 of the speaker sound cavity shell 3. The fan 4 drives the air to enter from the air inlet 11, pass through the gap between the speaker sound cavity shell 3 and the partition plate 5, enter the fan receiving slot 31, and blow out from the air outlet interface 51 of the partition plate 5 after passing through the fan 4, enter the atomization assembly 6, and blow out the mist generated by the atomization assembly 6. The air inlet channel of the fan 4 is composed of a relatively narrow channel formed by the gap between the speaker sound cavity shell 3 and the partition plate 5, which can prevent the noise generated by the fan 4 from being directly transmitted from the air inlet 11 to the outside world, thereby achieving a noise reduction effect. After testing, the noise value of the spray equipment using the above structure can be reduced to below 25dB. In addition, the present solution hides the fan 4 in the speaker sound cavity shell 3. When the speaker 2 is working, the speaker sound cavity shell 3 will vibrate along with the sound waves generated by the speaker 2. The vibration of the speaker sound cavity shell 3 and the vibration of the fan 4 are offset, which can prevent the vibration noise of the fan 4 from being transmitted outward through the supporting structure connected thereto, avoid the noise of the fan 4 from forming the background noise of the environment, reduce the interference with the sound emitted by the speaker 2, and make the sound effect purer and more transparent.

[0024] Among them, the atomization assembly 6 includes a water tank 61, an upper cover 62 and an atomizer 63, the water tank 61 includes a water tank body 611 and a water tank support part 612, the upper cover 62 includes an inner cover body 621 and an outer cover body 622, the inner cover body 621 is arranged in cooperation with the water tank body 611, and the outer cover body 622 is arranged in cooperation with the water tank support part 612.

[0025] Combination Figure 5 As shown, the water tank support part 612 is provided with a first air outlet 613, and the inner cover 621 is provided with a second air outlet 623; the first air outlet 613, the gap between the inner cover 621 and the outer cover 622, and the second air outlet 623 form an upper air outlet channel. The double-layer cover structure can directly form an air duct through the cover, and the wind generated by the base 1 is passed from the upper cover 62 into the water tank 61 through the air duct, and finally sprayed out through the spray port 624 in the center of the cover. The structure is exquisite and compact, and the integrity is strong.

[0026] In order to prevent the noise generated by the fan 4 from being directly transmitted to the outside through the air outlet channel, the partition plate 5 is also provided with a downwardly recessed wind pressure chamber 52, and the water tank support portion 612 is provided with a pressurized chamber 614 with a gradually decreasing cross-section corresponding to the wind pressure chamber 52, and the top of the pressurized chamber 614 is provided with the first air outlet 613. The wind blown out by the fan 4 passes from a chamber with a larger volume into the wind pressure chamber 52 with a smaller volume, where the wind pressure begins to increase; then, the air passes into the pressurized chamber 614, and since the wind cross-section of the pressurized chamber 614 gradually decreases, the pressure of the air passing through further increases, and finally it is ejected from the first air outlet 613. After entering the gap between the inner cover body 621 and the outer cover body 622, the pressure is slightly reduced again, and the air flow is slightly slowed down. After the change of the air outlet pressure, the intensity of the noise transmitted to the outside through the air is reduced, thereby achieving the noise reduction effect.

[0027] Preferably, the lower end of the pressurized chamber 614 extends into the wind pressure chamber 52, and the wind pressure chamber 52 is connected to the air outlet 41 through the space between the partition plate 5 and the water tank body 611. Since the lower end of the pressurized chamber 614 extends into the wind pressure chamber 52, the air entering the pressurized chamber 614 must first enter the wind pressure chamber 52 downward, and then detour upward to enter the pressurized chamber 614. During the detour, the noise will collide with the chamber wall and attenuate, further reducing the noise.

[0028] Preferably, a first air inlet plane 32 is provided on the upper portion of the speaker sound cavity housing 3, and a second air inlet plane 53 is provided on the partition plate 5 that is balanced with the first air inlet plane 32 and is at a predetermined distance from the first air inlet plane 32, and an air inlet gap is formed between the first air inlet plane 32 and the second air inlet plane 53. An air inlet gap is formed between the first air inlet plane 32 and the second air inlet plane 53, and the air inlet gap is used to reflect noise between the two planes, thereby reducing the noise value transmitted outward, and air can enter the position where the fan 4 is located from the square ring, thereby reducing noise and reducing air inlet wind resistance.

[0029] Preferably, an atomization control plate 64 is provided in the space between the partition plate 5 and the water tank body 611, and the air outlet 41 is arranged directly opposite to the atomization control plate 64. The wind blown by the fan 4 also has the effect of cooling the atomization control plate 64, thereby ensuring the long-term normal operation of the device.

[0030] Preferably, the air inlet 11 is a small circular hole, which is arranged in layers on the base 1 in the circumferential direction. More preferably, a cloth wrapping layer (not shown) is provided on the surface of the air inlet 11. The cloth wrapping layer can be formed by a cloth wrapped on the surface of the base 1 as a whole, or can be provided corresponding to the air inlet 11. The cloth wrapping layer itself has a decompression function and will not produce a sharp sound, so that the air intake achieves a silencing effect.

[0031] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
