[0047] The present utility model provides a humidifier 10.

[0048] Please refer to Figures 2 to 6 , in an embodiment of the present utility model, the humidifier 10 includes a housing 100, a liquid storage tank 200, an atomization assembly 300, and a cover 400. The housing 100 has a receiving cavity 110 and an installation opening 120. The installation opening 120 is located at the upper end of the housing 100 and communicates with the receiving cavity 110. At least a part of the liquid storage tank 200 is disposed in the receiving cavity 110. A first fog collection cavity 130 is defined between the outer wall of the liquid storage tank 200 and the inner wall of the housing 100. The atomization assembly 300 is disposed in the receiving cavity 110 and is used to atomize the liquid provided by the liquid storage tank 200 to form water mist and then discharge it into the first fog collection cavity 130. The cover 400 has a second fog collection cavity 410, an inlet fog port 420, and an outlet fog port 430 that communicate with the second fog collection cavity 410. The cover 400 is disposed at the installation opening 120, and the first fog collection cavity 130 communicates with the inlet fog port 420.

[0049] It can be understood that the liquid storage tank 200 can be entirely disposed in the receiving cavity 110, or a part of the liquid storage tank 200 can be disposed in the receiving cavity 110. The liquid storage tank 200 is used to store liquid. The liquid storage tank 200 can be detachably installed in the housing 100 so that the liquid storage tank 200 can be taken out for adding water or other liquids. Of course, water can also be directly added to the liquid storage tank 200 in the housing 100. The atomization assembly 300 can include an atomizing member. The atomizing member is used to atomize water, and there can be various types of atomizing members, including but not limited to: ultrasonic transducers, film atomizers, etc. For example, an ultrasonic transducer uses electronic high-frequency oscillation to cause the atomizing sheet to resonate at high frequency to generate ultrasonic waves. When the ultrasonic waves propagate in water, cavitation occurs. The water around the cavity is crushed into water particles by the cavitation explosion occurring between water and air, thereby forming water mist.

[0050] Further, one, two or more cavities and / or water tanks may be provided in the accommodation cavity 110, and the atomization assembly 300 may be disposed in the water tank to generate water mist in the water tank and then discharge it to the second mist collection cavity 410. The liquid storage tank 200 and the cover body 400 may be separately provided. Of course, the liquid storage tank 200 and the cover body 400 may also be an integral structure, such as integrally formed. In addition, the liquid storage tank 200 may be inserted into the accommodation cavity 110 from the installation port 120, which is convenient for disassembling, assembling and adding water to the liquid storage tank 200. Of course, it may also be installed from one side of the housing 100, and the specific method is not limited herein. During assembly, the liquid storage tank 200 may be first installed in the accommodation cavity 110, and then the cover body 400 may be installed on the liquid storage tank 200 at the installation port 120; or, the cover body 400 and the liquid storage tank 200 may be first assembled together, and then the liquid storage tank 200 may be installed in the accommodation cavity 110.

[0051] Further, a first mist collection cavity 130 is defined between the outer wall of the liquid storage tank 200 and the inner wall of the housing 100, that is, the first mist collection cavity 130 is located outside the liquid storage tank 200. The atomization assembly 300 discharges the formed water mist to the first mist collection cavity 130, and the first mist collection cavity 130 conducts the first aggregation of the water mist. At the same time, since the first mist collection cavity 130, the mist inlet 420, the second mist collection cavity 410 and the mist outlet 430 are connected in sequence, the water mist after the first aggregation will flow into the second mist collection cavity 410 along the mist inlet 420 for the second aggregation. The secondary aggregation of the water mist enables the water mist to form a water mist group with a certain pressure, which is beneficial to improving the flow velocity of the water mist, and the water mist can be ejected and discharged from the mist outlet 430, so that the mist outlet effect of the water mist can be improved. The dotted arrows in the accompanying drawings of the specification indicate the flow direction of the water mist.

[0052] In addition, the installation port 120 is located at the upper end of the housing 100, the cover body 400 is disposed at the installation port 120, the cover body 400 has a second mist collection cavity 410, and the first mist collection cavity 130 is communicated with the second mist collection cavity 410, so that the water mist can flow in the upward direction, which is beneficial to improving the flow velocity of the water mist, and thus further enhances the mist outlet effect of the water mist.

[0053] The humidifier 10 of the present utility model includes a housing 100, a liquid storage tank 200, an atomization assembly 300 and a cover body 400. An installation opening 120 is located at the upper end of the housing 100, and the cover body 400 is arranged at the installation opening 120. A first fog collection cavity 130 is defined between the outer wall of the liquid storage tank 200 and the inner wall of the housing 100. The cover body 400 has a second fog collection cavity 410, a fog inlet 420 and a fog outlet 430 that communicate with the second fog collection cavity 410. The first fog collection cavity 130 communicates with the fog inlet 420. The atomization assembly 300 is arranged in the accommodation cavity 110 and is used for atomizing the liquid provided by the liquid storage tank 200 to form water mist and discharging it into the first fog collection cavity 130. With such a setting, the first fog collection cavity 130, the fog inlet 420, the second fog collection cavity 410 and the fog outlet 430 are sequentially communicated. The water mist formed by the atomization assembly 300 can first gather in the first fog collection cavity 130, then flow into the second fog collection cavity 410 along the fog inlet 420 for secondary aggregation, and then be discharged from the fog outlet 430. During this process, the water mist flows smoothly in the upward direction, and the concentration of the water mist increases after secondary aggregation. The high-concentration water mist can be quickly ejected from the fog outlet 430, that is, the water mist ejected from the fog outlet 430 is not only of high concentration but also fast in speed. Thus, the fog outlet effect of the water mist is enhanced. It can be seen that the fog outlet effect of the humidifier 10 of the present application is obvious, the perception of the user on the water mist ejected by the humidifier 10 is improved, and the situation of user misjudgment is reduced.

[0054] In one embodiment, the volume of the second fog collection cavity 410 is smaller than the volume of the first fog collection cavity 130. With such a setting, when the water mist flows from the first fog collection cavity 130 into the second fog collection cavity 410, the volume of the fog collection cavity decreases, the water mist is further squeezed, and the concentration of the water mist increases. Thus, the fog outlet effect of the water mist is further enhanced.

[0055] Please refer to Figures 3 to 5 , in one embodiment, a partition member 500 is provided in the housing 100. The partition member 500 divides the first fog collection cavity 130 into a first sub-cavity 140 and a second sub-cavity 150. The atomization assembly 300 is used for discharging water mist into the first sub-cavity 140. The first sub-cavity 140, the second sub-cavity 150, the fog inlet 420, the second fog collection cavity 410 and the fog outlet 430 are sequentially communicated.

[0056] It can be understood that the separator 500 can be provided on the inner wall of the housing 100, or on the outer wall of the liquid storage tank 200. Of course, the separator 500 can also be integrally formed with the housing 100, and specifically, it is not limited here. The separator 500 divides the first fog collection chamber 130 into a first sub-chamber 140 and a second sub-chamber 150. The water mist formed by the atomization assembly 300 flows through the first sub-chamber 140, the second sub-chamber 150, the fog inlet 420, and the second fog collection chamber 410 in sequence and then is discharged outward from the fog outlet 430. With such a setting, the water mist can first gather in the first sub-chamber 140, then in the second sub-chamber 150, and finally in the second fog collection chamber 410. By gathering the water mist three times, the concentration of the water mist is increased. The high-concentration water mist can be quickly ejected from the fog outlet 430, that is, the water mist ejected from the fog outlet 430 is not only of high concentration but also fast in speed, thus further enhancing the fog ejection effect of the water mist.

[0057] In one embodiment, the first sub-chamber 140, the second sub-chamber 150, and the second fog collection chamber 410 are arranged in sequence from bottom to top along the height direction of the housing 100. With such a setting, it is beneficial to improve the smoothness of the water mist flow and the fog ejection speed and fog ejection effect of the water mist.

[0058] Please refer to Figure 4 , in one embodiment, the volumes of the first sub-chamber 140, the second sub-chamber 150, and the second fog collection chamber 410 are gradually decreased. With such a setting, when the water mist flows through the first sub-chamber 140, the second sub-chamber 150, and the second fog collection chamber 410 in sequence, as the volumes of the three fog collection chambers gradually decrease, the water mist is gradually squeezed, and the concentration of the water mist is further increased, thus further enhancing the fog ejection effect of the water mist.

[0059] In one embodiment, the first sub-chamber 140 and the second sub-chamber 150 are communicated through a fog passing port 160; the fog passing port 160 is provided on the separator 500; and / or, at least part of the separator 500 is spaced from the outer wall of the liquid storage tank 200 to form the fog passing port 160; and / or, at least part of the separator 500 is spaced from the inner wall of the housing 100 to form the fog passing port 160.

[0060] It can be understood that the mist outlet 160 connects the first sub-chamber 140 and the second sub-chamber 150, and the water mist flow in the first sub-chamber 140 flows into the second sub-chamber 150 through the mist outlet 160. The formation method of the mist outlet 160 is not limited. For example, the mist outlet 160 is provided on the partition; for another example, the mist outlet 160 is formed between the partition 500 and the outer wall of the liquid storage tank 200, that is, at least part of the partition 500 and the outer wall of the liquid storage tank 200 are spaced to form the mist outlet 160; for another example, the mist outlet 160 is formed between the partition 500 and the inner wall of the shell 100, that is, at least part of the partition 500 and the inner wall of the shell 100 are spaced to form the mist outlet 160. Such a configuration allows the water mist to flow smoothly from the first sub-chamber 140 into the second sub-chamber 150. The formation method of the mist outlet 160 is simple, which is conducive to simplifying the structure of the humidifier 10.

[0061] In one embodiment, the humidifier 10 further includes a light emitting component 600, which is disposed on the partition 500 and located in the second sub-cavity 150, and the light emitting component 300 is used to emit light to illuminate the cover 400 and / or the water mist flowing through the mist inlet 420. Such a configuration makes full use of the space in the housing 100, and facilitates the installation of the light emitting component 600. The light emitted by the light emitting component 600 will be reflected and refracted when irradiating the water mist, and can present a flame burning effect in conjunction with the flow of the water mist, thereby further enhancing the misting effect of the humidifier 10 and improving the user's perception of the water mist sprayed by the humidifier 10.

[0062] In one embodiment, at least part of the second mist collecting chamber 410 is located directly above the liquid storage tank 200, and the first mist collecting chamber 130 is arranged in a ring shape around the circumference of the liquid storage tank 200. It can be understood that the second mist collecting chamber 410 is not connected to the inner cavity of the liquid storage tank 200, and the first mist collecting chamber 130 is arranged in a ring shape around the circumference of the liquid storage tank 200, so that the space in the housing 100 is fully utilized, and the water mist can be evenly distributed around the liquid storage tank 200 in the housing 100, which is conducive to improving the uniformity of the water mist sprayed by the humidifier 10, and making the water mist flow into the second mist collecting chamber 410 more concentratedly and then discharged outward.

[0063] See also Figures 3 to 6, in one embodiment, the cover body 400 includes a mist outlet cover 440 and a bottom cover 450. The bottom cover 450 is disposed at the installation opening 120 and is detachably connected to the housing 100. The mist outlet cover 440 is detachably disposed on the bottom cover 450 and encloses with the bottom cover 450 to form the second mist collecting cavity 410. It can be understood that the mist outlet cover 440 is detachably disposed on the bottom cover 450, and the bottom cover 450 is detachably disposed on the housing 100, making the cover body 400 easy to assemble and disassemble, and also facilitating the cleaning of the second mist collecting cavity 410. As for the way of detachable connection, it is not limited, for example, but not limited to, screw connection, snap connection, etc.

[0064] In one embodiment, the bottom cover 450 is provided with the mist inlet 420, and the mist outlet cover 440 is provided with the mist outlet 430. It can be understood that the mist outlet cover 440 is disposed on the bottom cover 450. The bottom cover 450 is provided with the mist inlet 420, and the mist outlet cover 440 is provided with the mist outlet 430. The mist outlet 430 is located above the mist inlet 420, so that the water mist can flow smoothly from bottom to top in the humidifier 10.

[0065] Specifically in this embodiment, one of the mist outlet cover 440 and the bottom cover 450 is provided with a hook, and the other is provided with a slot, and the hook is snapped into the slot. In addition, the bottom cover 450 is further provided with a groove, and the periphery of the mist outlet cover 440 is disposed in the groove. With such a setting, the mist outlet cover 440 and the bottom cover 450 are easy to form the second mist collecting cavity 410, and at the same time, the mist outlet cover 440 can rotate smoothly in the groove.

[0066] In one embodiment, the mist outlet cover 440 is rotatably disposed on the bottom cover 450, and the geometric center of the mist outlet 430 is offset from the rotation center of the mist outlet cover 440. With this arrangement, when the mist outlet cover 440 is rotated, the position of the mist outlet 430 on the mist outlet cover 440 can vary relative to the housing 100. That is, by rotating the mist outlet cover 440, the position of the mist outlet 430 can be adjusted to meet the requirements of the humidifier 10 for mist output in different directions. For example, the mist outlet 430 is strip-shaped and is located on one side of the rotation center of the mist outlet cover 440. That is, the strip-shaped mist outlet 430 is offset from the rotation center of the mist outlet cover 440. When the mist outlet cover 440 is rotated, the mist outlet 430 can move 360 degrees around the rotation center of the mist outlet cover 440 as the mist outlet cover 440 rotates. In this way, the mist outlet 430 can have multiple mist output positions, and thus can meet the mist output requirements of users in different directions. It can be understood that the geometric center of the mist outlet 430 is the most central position of the mist outlet 430. When the mist outlet cover 440 rotates around its rotation center, the most central position of the mist outlet 430 on the mist outlet cover 440 varies relative to both the housing 100 and the bottom cover 450, so that the position of the mist outlet 430 can be adjusted as needed.

[0067] In one embodiment, the upper end of the liquid storage tank 200 is detachably connected to the bottom cover 450. With this arrangement, the bottom cover 450 can limit and fix the upper end of the liquid storage tank 200, thereby improving the stability of the installation of the liquid storage tank 200 in the housing 100 and improving the utilization rate of the bottom cover 450.

[0068] Please refer to Figure 6 , in one embodiment, the bottom cover 450 is provided with a first limiting portion 451 and a second limiting portion 452, the mounting opening 120 is provided with a flanging 121, the flanging 121 is provided with a first mating portion 122, the upper end of the liquid storage tank 200 is provided with a second mating portion 210, the first limiting portion 451 is in limiting and clamping connection with the first mating portion 122, and the second limiting portion 452 is in limiting and clamping connection with the second mating portion 210. It can be understood that by providing the flanging 121, it is convenient for the bottom cover 450 to be positioned and installed, and the bottom cover 450 is clamped with the housing 100 and the bottom cover 450 is clamped with the liquid storage tank 200, which is beneficial to simplifying the structure and assembly method of the bottom cover 450, thereby reducing the assembly difficulty of the humidifier 10.

[0069] In one embodiment, one of the first limiting portion 451 and the first mating portion 122 is a limiting protrusion, and the other is a limiting groove, and the limiting protrusion is clamped in the limiting groove; and / or, one of the second limiting portion 452 and the second mating portion 210 is a hook, and the other is a slot, and the hook is clamped in the slot.

[0070] Please refer to Figure 1 It can be seen that, specifically in this solution, the first limiting portion 451 is located outside the bottom cover 450, and the second limiting portion 452 is located inside the bottom cover 450. The first limiting portion 451 is a limiting protrusion, and the first mating portion 122 is a limiting groove. That is, the outside of the bottom cover 450 is provided with a limiting protrusion, and the limiting groove is provided on the flanging 121. The limiting protrusion is clamped in the limiting groove, so that the bottom cover 450 can be stably installed on the housing 100. The number of the limiting protrusions and the limiting grooves can be multiple, and the multiple limiting protrusions and the multiple limiting grooves are arranged in one-to-one correspondence, thus ensuring the stability of the installation of the bottom cover 450 on the housing 100.

[0071] It can be understood that the outer peripheral wall of the bottom cover 450 is in abutting contact with the flanging 121 at the installation opening 120. There is no gap or the gap is small between the outer peripheral wall of the bottom cover 450 and the flanging 121.

[0073] In an embodiment, the humidifier 10 further includes a blowing device, which is arranged in the accommodation cavity 110 and is used for blowing air towards the mist outlet 430. It can be understood that the position of the blowing device is not limited, and it only needs to be able to blow air towards the mist outlet 430. For example, the blowing device blows air into the first mist collecting cavity 130, so that the air pressure and flow rate of the water mist in the first mist collecting cavity 130 are increased. The water mist flows through the second mist collecting cavity 410 and is further pressurized and then sprayed out of the mist outlet 430, thus enhancing the mist outlet effect. The blowing device can include a fan, such as a worm fan, etc. The worm fan has a good silent air outlet effect, making the blown air softer.

[0074] In one embodiment, the humidifier 10 further includes a lighting assembly 600 disposed on the housing 100 for emitting light and irradiating the water mist in the first mist collecting chamber 130 and / or the second mist collecting chamber 410. With such an arrangement, when the light irradiates the water mist, it will be reflected and refracted, and in cooperation with the flow of the water mist, it can present an effect of flame combustion, thereby further enhancing the mist output effect of the humidifier 10 and improving the user's perception of the water mist ejected by the humidifier 10. Specifically, in this solution, the lighting assembly 600 is disposed in the accommodating chamber 110 for emitting light and irradiating the water mist in the first mist collecting chamber 130, which facilitates the installation of the lighting assembly 600 and enables the light to irradiate the water mist in the first mist collecting chamber 130 and the second mist collecting chamber 410 in sequence as the water mist flows, which is beneficial to increasing the irradiation range of the water mist and further enhancing the mist output effect of the humidifier 10.

[0075] In one embodiment, the outer peripheral wall of the cover body 400 abuts against the shell wall of the housing 100, and at least part of the cover body 400 is located above the liquid storage tank 200, and the cover body 400 abuts against the outer wall of the liquid storage tank 200. With such an arrangement, there is no gap or a small gap between the cover body 400 and the housing 100, and there is no gap or a small gap between the cover body 400 and the outer wall of the liquid storage tank 200. When the water mist passes through the gap between the cover body 400 and the housing 100, a thin film will be formed at the gap to block the water mist from flowing outwards through the gap. When the water mist passes through the gap between the cover body 400 and the liquid storage tank 200, a thin film will be formed at the gap to block the continuous inflow of the water mist, so that the water mist can smoothly flow into the second mist collecting chamber 410 and then be discharged outwards.
