Description

Technical Field

[0001] The utility model relates to an indoor humidity regulating device, in particular to an evaporative humidifier with an anti-dumping and noise reduction mechanism. Background Art

[0002] Humidifiers are common indoor humidity control devices, which mainly use ultrasonic transducers to generate high-frequency vibrations on water, turning water droplets into mist and dispersing them into the indoor space, thereby adjusting the indoor humidity. However, humidifiers with this structure have the defects of being unable to disinfect the water in the water tank and having a low output of mist. In addition to reducing the diffusion efficiency of the mist, the mist also contains more bacteria, so evaporative humidifiers using electric heating have appeared on the market.

[0003] Chinese patent document CN217584720U discloses an evaporative humidifier for increasing the humidification amount, which uses a heating plate to heat the water body so that the water body generates water vapor, and increases the speed of water vapor generation on the boiling water surface through a humidification lifting component, accelerates the discharge of water vapor from the air duct, and realizes the humidification of the indoor environment by water vapor. Although this structure realizes the conversion of water into water vapor after boiling and discharges it into the indoor space for humidification, it still has two technical defects. First, since the water body generates water vapor and is discharged from the air duct, the water body in the heating tank is in a connected state with the outside world. When the humidifier is tilted or overturned, boiling water will flow out of the air duct, seriously affecting the personal safety of the user. Second, the amount of steam generated when the water body evaporates is large, and it constantly hits the edge of the air duct when it is discharged, which will produce a lot of noise. Summary of the invention

[0004] The utility model aims to overcome the deficiencies of the prior art and provide an evaporative humidifier which has strong safety and can reduce the noise of steam output.

[0005] The purpose of the utility model is achieved as follows: An evaporative humidifier with an anti-dumping and noise reduction mechanism is mainly composed of a cover assembly, a water storage component and a control assembly, and the above three are connected together in sequence from top to bottom. The control assembly has a heating component, which can heat the water in the water storage component, and after the water generates steam, the steam is output to the outside through the cover assembly. The cover assembly includes a seat body, a surface cover and a sealing module, the seat body is located at the top of the water storage component and has a first mist outlet; the surface cover is located on the seat body and has a second mist outlet; the sealing module is arranged in the seat body, and can close the first mist outlet when the water storage component is dumped, so as to prevent the water from flowing from the water storage component to the outside.

[0006] By optimizing the evaporative humidifier with an anti-dumping and noise reduction mechanism, the sealing module includes a closing plate, a positioning column, a gravity member and an elastic member. The closing plate corresponds to the position of the first mist outlet so that the first mist outlet can be closed when the closing plate moves. The positioning column is fixed to the closing plate and movably connected to the seat body to guide the closing and opening process of the closing plate. The gravity member is arranged between the closing plate and the face cover, which reduces the pressure exerted by the gravity member on the closing plate when the water storage component dumps. The elastic member is sleeved on the positioning column, which can reset the movement of the positioning column on the seat body.

[0007] By further refining the evaporative humidifier with an anti-dumping noise reduction mechanism, the closing plate is also provided with a soft sealing sleeve, which can cut off the connection between the water storage component and the first mist outlet, thereby enhancing the sealing performance of the closing plate.

[0008] By further refining the evaporative humidifier with an anti-dumping noise reduction mechanism, the positioning column is also provided with a limiting piece, which is fixedly connected to the positioning column and located at one end close to the face cover to position the elastic stroke of the elastic member.

[0009] By optimizing the evaporative humidifier with an anti-dumping noise reduction mechanism, the second mist outlet, the first mist outlet and the water storage component are arranged in a staggered manner in the vertical direction to avoid direct discharge of steam in the water storage component.

[0010] By optimizing the evaporative humidifier with an anti-dumping noise reduction mechanism, the seat body is also provided with a baffle, which is fixed to the seat body and can change the flow direction of the steam in the water storage component so that the steam has a turning effect when flowing, thereby reducing the noise it emits.

[0011] The evaporative humidifier with an anti-dumping and noise reduction mechanism has the following beneficial effects:

[0012] 1. The utility model adopts a combined structure of a first mist outlet, a second mist outlet and a sealing module. When the water storage component falls over, the sealing module can close the first mist outlet, completely blocking the connection between the inner cavity of the water storage component and the outside world, preventing the water in the water storage component from flowing out to the outside world through the first mist outlet and the second mist outlet, and preventing the heated water from scalding the user, thereby improving the safety and reliability of the humidifier.

[0013] 2. The second mist outlet, the first mist outlet and the water storage component of the utility model are arranged in a staggered manner in the vertical direction, and a baffle is provided on the seat. The staggered steam outlets can form a bypass channel with a shielding effect, which can firstly prevent the rapid discharge of steam in the water storage component, and secondly reduce the friction between the steam and the edge of the steam outlet when the steam is discharged quickly, thereby generating noise. The baffle can change the flow direction of the steam, further slowing down the discharge speed of the steam and reducing the friction. BRIEF DESCRIPTION OF THE DRAWINGS

The following embodiments are one or several examples that can realize the new technical solutions of the utility model, obtain corresponding technical effects, and solve corresponding technical problems, and do not limit the protection scope of the utility model to only within the scope of the following embodiments.

[0022] according to Figures 1 to 6As shown, the evaporative humidifier with anti-dumping and noise reduction mechanism of the utility model is mainly composed of a cover assembly, a water storage component 1, a control assembly 2 and a heating component 3. The cover assembly, the water storage component 1 and the control assembly 2 are arranged together in a detachable fixed manner from top to bottom, and the heating component 3 is arranged in the control assembly 2, and its position can be close to the bottom of the water storage component 1 to heat the water in the water storage component 1. The control assembly 2 and the heating component 3 are arranged in an electrically connected manner with the outside world, and the control assembly 2 and the heating component 3 can be connected in series according to the usage conditions to realize the control assembly 2 to control the on and off, working time, etc. of the heating component 3. The positions of the water storage component 1 and the heating component 3 correspond to each other, so that the water in the water storage component 1 is heated and evaporated when the heating component 3 is working, and the steam can be output to the outside world through the cover assembly. The cover assembly includes a seat body 41, a cover 42 and a sealing module. The seat body 41 is located at the top of the water storage component 1. It is detachably fixedly connected to the water storage component 1 to seal the inside of the water storage component 1. The seat body 41 is provided with a first mist outlet 43, which can be directly opened on the seat body 41 so that the steam in the water storage component 1 can be output from the first mist outlet 43; the cover 42 is provided on the seat body 41. It is also detachably fixedly connected to the seat body 41. The cover 42 has a second mist outlet 44, which can also be directly opened on the cover 42 so that the first mist outlet 43 and the second mist outlet 44 form a passage connecting the inside of the water storage component 1 and the outside. The sealing module is provided in the seat body 41. When the water storage component 1 is tilted, it can close the first mist outlet 43 to prevent the water in the water storage component 1 from flowing out to the outside through the first mist outlet 43 and the second mist outlet 44.

[0023] For the control component 2 in the utility model, those skilled in the art can refer to the records in the Chinese patent document CN201589370U, and only need to select the control module according to the use requirements and make the heating component 3 work normally, which will not be described in detail here. As for the heating component 3, those skilled in the art can refer to the records in the Chinese patent documents CN219103209U and CN219103210U, which will not be described in detail here.

[0024] In one embodiment of the utility model, the sealing module includes a closing plate 51, a positioning column 52, a gravity member 53 and an elastic member 54. The closing plate 51 and the seat body 41 are separated and correspond to the position of the first mist outlet 43 so as to open or close the first mist outlet 43 during the movement of the closing plate 51. The positioning column 52 is located on the closing plate 51, and is fixed to the closing plate 51, or the two are processed in an integrally formed manner. The positioning column 52 is movably connected to the seat body 41 along its axial direction to drive the closing plate 51 to move back and forth in two directions away from or close to the seat body 41. The gravity member 53 is arranged between the closing plate 51 and the face cover 42, and is crimped onto the closing plate 51. It can be a steel ball or a movable weight. The gravity member 53 enables the water storage component 1 to always be in a separated state between the closing plate 51 and the seat body 41 under normal working conditions. The elastic member 54 is sleeved on the positioning column 52 to generate elastic force when the closing plate 51 is separated from the base 41 and to generate elastic restoring force when the gravity member 53 leaves the closing plate 51 , so that the closing plate 51 is connected to the base 41 and the first mist outlet 43 is closed.

[0025] In another embodiment of the utility model, the closing plate 51 is further provided with a soft sealing sleeve 55. The soft sealing sleeve 55 is made of silicone or rubber and is located at the side where the closing plate 51 is connected to the first mist outlet 43. A buckle 57 can be provided between the soft sealing sleeve 55 and the closing plate 51 to achieve the snap-fit ​​fixation of the two. When the elastic member 54 generates an elastic restoring force to move the closing plate 51 toward the seat body 41, the soft sealing sleeve 55 can cut off the connection between the water storage component 1 and the first mist outlet 43 to prevent the water in the water storage component 1 from flowing out through the first mist outlet 43.

[0026] In another embodiment of the present invention, the positioning column 52 is further provided with a limiting piece 56. The limiting piece 56 and the positioning column 52 can be processed in an integrally formed manner, and is located at one end close to the cover 42 to position the end of the elastic member 54, thereby ensuring the reliability of the elastic force or elastic restoring force of the elastic member 54.

[0027] In another embodiment of the utility model, the second mist outlet 44, the first mist outlet 43 and the water storage part 1 are arranged in sequence in the vertical direction and arranged in a staggered manner. This structure can prevent the steam in the water storage part 1 from being quickly discharged to the outside. In addition to preventing the user from being scalded by the quickly discharged steam, it can also reduce the friction between the steam and the side walls of the second mist outlet 44 and the first mist outlet 43 when the steam flows, and reduce the noise when the steam is discharged.

[0028] In another embodiment of the utility model, the seat body 41 is further provided with a baffle 45. The baffle 45 and the seat body 41 are processed in an integrally formed manner and can change the flow direction of the steam of the water storage component 1. This structure can further reduce the flow speed of the steam and reduce the friction between the steam and the side walls of the second mist outlet 44 and the first mist outlet 43.
