Description

Technical Field

[0001] The invention relates to the technical field of household appliances, and in particular to a drainage noise reduction structure and a humidifier. Background Art

[0002] Humidifiers have become the preferred way for residents to relieve dry air. With the continuous improvement of people's living standards and the continuous advancement of science and technology, users have higher and higher requirements for the quality of humidifier products.

[0003] Existing humidifiers usually use the ultrasonic atomization principle. When working, the ultrasonic vibrator vibrates at a high frequency to atomize water. The atomized water is blown to the outside space under the action of the fan to achieve humidification of the outside space. However, the ultrasonic vibrator will also stir up small water droplets during the vibration process. The water droplets will hit the shell wall to make noise, and the small water droplets will move toward the mist outlet pipe under the action of the fan wind. When encountering the pipe wall, the water droplets condense and gather, increase in weight, and then drip from the condensed pipe wall, forming a dripping sound. Especially when the humidifier is used in the bedroom, it brings a bad user experience to the user. Summary of the invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the problem in the prior art that water droplets generated during the atomization process of the humidifier are prone to generate noise, thereby providing a drainage noise reduction structure and a humidifier.

[0005] In order to solve the above problems, the present invention provides a drainage and noise reduction structure including a guide member, which is arranged at the mist outlet; a filter, which is arranged on the guide member and opposite to the mist outlet; wherein an end of the filter close to the guide member is inclined toward the mist outlet.

[0006] Furthermore, there is an inclination angle A between the filter screen and the guide member, and the value range of the inclination angle A is [10°, 30°].

[0007] The drainage and noise reduction structure in the present invention further comprises a mist collecting portion, which is arranged at the mist outlet, and the guide member guides the water mist to the mist collecting portion.

[0008] Furthermore, the mist collecting portion is in a funnel structure, and the head of the funnel is arranged on the mist outlet.

[0009] Furthermore, the guide member includes: at least one guide column, which is arranged on the mist collecting part; a filter mounting frame, which is arranged on the guide column and at one end away from the mist collecting part, and the filter is arranged on the filter mounting frame.

[0010] Furthermore, a mounting hole is provided on the mist collecting portion, and the guide column can be movably disposed in the mounting hole.

[0011] Furthermore, the guide member further comprises a supporting portion, one end of which is arranged on the mist collecting portion, and the other end of which is arranged on the filter mounting frame.

[0012] The present invention also provides a humidifier comprising: any one of the drainage noise reduction structures described above.

[0013] The technical solution of the present invention has the following advantages:

[0014] 1. The drainage and noise reduction structure in the present invention includes a guide member, which is arranged at the mist outlet; a filter, which is arranged on the guide member and opposite to the mist outlet; wherein the end of the filter close to the guide member is inclined toward the mist outlet.

[0015] The water mist coming out of the mist outlet is acted on the filter under the action of the wind force of the fan. The structural characteristics of the filter can block the small water droplets entrained in the water mist. The water droplets remaining on the filter are gathered. Under the structural characteristics of the inclined filter, they are affected by their own gravity and flow to the guide member. They slide down the guide member to the mist outlet and are vibrated and atomized by the ultrasonic vibration head again, which effectively solves the noise problem caused by the direct fall of water droplets in the water mist in the prior art.

[0016] 2. In the drainage and noise reduction structure of the present invention, there is an inclination angle A between the filter and the guide member, and the value range of the inclination angle A is [10°, 30°]. This inclination angle can ensure that the filter has an effective interception area of ​​​​water mist as large as possible while also ensuring a good drainage effect.

[0017] 3. The drainage noise reduction structure in the present invention also includes a mist collecting part, which is arranged at the mist outlet, and the guide member guides the water mist to the mist collecting part. The mist collecting part is arranged because the humidifier has different gears. When the humidifier is in a larger mist outlet gear, the amount of water flowing up and down the guide member is large and may drip directly. The mist collecting part can accelerate the flow of the drained water on the one hand, and prevent the water from dripping directly into the water tank in the humidifier base on the other hand, causing the dripping sound.

[0018] 4. The drainage and noise reduction structure in the present invention has a funnel-shaped mist collecting portion, and the head of the funnel is arranged on the mist outlet. The funnel-shaped structure can accelerate the downward flow of the liquid on the one hand, and is conducive to the collection of water droplets on the guide member on the other hand.

[0019] 5. In the drainage and noise reduction structure of the present invention, a mounting hole is provided on the mist collecting part, and the guide column can be movably arranged in the mounting hole. As mentioned above, the humidifier has different gears. When in different gears, the amount of water droplets intercepted by the filter is different, and the amount of water guided down by the guide member is also different. In order to effectively guide the intercepted water as much as possible, the height of the guide column is adjusted in the present invention to increase the length of the guide path. It is only necessary to ensure that the height of the guide column at the maximum gear can effectively guide the water to meet the noise reduction requirements of the humidifier. Therefore, the guide column is movably arranged in the mounting hole in the present invention to facilitate the adjustment of the noise reduction effect.

[0020] 6. The guide member in the drainage and noise reduction structure of the present invention also includes a support portion, one end of which is arranged on the mist collecting portion, and the other end is arranged on the filter mounting frame. The support portion is mainly arranged to increase the stability of the filter mounting frame to prevent the filter from vibrating under the action of the wind force of the fan or other vibrations, causing the water droplets intercepted by the filter to directly drip and generate noise.

[0033] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0035] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0037] Example 1

[0038] Figures 1 to 3 A drainage noise reduction structure provided for this embodiment includes: a guide member 1, arranged at the mist outlet 2; a filter 3, arranged on the guide member 1 and opposite to the mist outlet 2; wherein the end of the filter 3 close to the guide member 1 is inclined toward the mist outlet 2.

[0039] The drainage noise reduction structure in this embodiment is used in a humidifier, specifically placed in the mist outlet tube 6 of the humidifier. The water mist generated in the humidifier base enters the mist outlet tube 6 through the mist outlet 2, and is then reduced in noise by the drainage noise reduction structure installed in the mist outlet tube.

[0040] Specifically, the water mist coming out of the mist outlet 2 acts on the filter 3 under the action of the wind force of the fan. The structural characteristics of the filter 3 can block the small water droplets entrained in the water mist, and the water droplets remaining on the filter 3 are gathered. Under the structural characteristics of the inclined filter 3, under the influence of their own gravity, they will flow to the guide member 1, slide down the guide member 1 to the mist outlet 2, and be vibrated and atomized by the ultrasonic vibration head again, which effectively solves the noise problem caused by the direct falling of water droplets in the water mist in the prior art.

[0041] It should be explained that the above-mentioned filter 3 is a common physical filter with filter holes processed thereon. The fineness of the filter holes determines the size of the water droplets that can be filtered. The smaller the filter holes, the smaller the volume of water droplets that can be intercepted. Of course, the air output will be affected to a certain extent.

[0042] Furthermore, there is an inclination angle A between the filter 3 and the guide member 1, and the value range of the inclination angle A is [10°, 30°]. The inclination angle A in this embodiment is 30 degrees. This inclination angle A can ensure that the filter has an effective interception area of ​​​​the water mist as large as possible while also ensuring a better drainage effect.

[0043] Because the humidifier has different gears, when the humidifier is in a larger mist output gear, the amount of water flowing up and down the guide member 1 is large and may drip directly. Therefore, this embodiment also includes a mist collecting part 4, which is installed at the mist outlet 2. The guide member 1 guides the water mist to the mist collecting part 4. On the one hand, it can speed up the flow of the water that is drained down, and on the other hand, it can also prevent the water from dripping directly into the water tank in the humidifier base and causing dripping sounds. Furthermore, the mist collecting part 4 is a funnel structure, and the head of the funnel is set on the mist outlet 2. The funnel-shaped structure can speed up the downward flow of the liquid on the one hand, and on the other hand, it is conducive to the collection of water droplets on the guide member 1.

[0044] Furthermore, the guide member 1 in this embodiment includes: two guide columns 11, which are installed on the mist collecting part 4, and a mounting hole is formed on the mist collecting part 4. The guide column 11 can be movably arranged in the mounting hole. The shaft section of the guide column 11 arranged in the mounting hole adopts an interference fit with the mounting hole member. Under the action of external force, the length of the guide column 11 installed in the mounting hole can be adjusted. As mentioned above, the humidifier has different gears. When it is in different gears, the amount of water droplets intercepted by the filter 3 is different, and then the amount of water guided down by the guide member 1 is also different. In order to effectively guide the intercepted water as much as possible, in this embodiment, the height of the guide column 11 is adjusted to increase the length of the guide path. It is only necessary to ensure that the height of the guide column 11 at the maximum gear can effectively guide the water to meet the noise reduction requirements of the humidifier. Therefore, in this embodiment, the guide column 11 is movably arranged in the mounting hole to facilitate the adjustment of the noise reduction effect.

[0045] In some other embodiments, the number of the guide columns 11 may be one, three, etc.

[0046] In some other embodiments, the cooperation between the guide column 11 and the mounting hole can also be in the form of screw connection. The mounting hole is processed into a threaded hole, and a corresponding threaded section is processed on the guide column 11. The height of the guide column 11 can be adjusted by different numbers of screw connections.

[0047] In some other embodiments, when the guide column 11 and the mounting hole are installed, additional structures can also be used to fix them, such as fixing them with a top screw.

[0048] The above-mentioned guide member 1 also includes a filter mounting frame 12, which is directly formed on the end of the guide column 11 away from the mist collecting part 4. The filter mounting frame 12 is as shown in FIG. Figure 1 As shown in the figure, it is a frame structure, and a support edge is formed into the frame at the edge of the lower end surface of the frame. The filter 3 is installed on the filter mounting frame 12, and is supported by the support edge and constrained by the frame to achieve fixation.

[0049] Furthermore, the guide member 1 in this embodiment further includes a support portion 13, one end of which is mounted on the mist collecting portion 4, and the other end is formed on the filter mounting frame 12. The support portion 13 in this embodiment is also a columnar structure, specifically a cylindrical structure, and there are two of them, and one end of which is mounted on the mist collecting portion 4 is arranged away from the guide column 11. Similarly, the number of the support portions 13 can also be one or more.

[0050] Example 2

[0051] like Figure 4 As shown, a humidifier provided in this embodiment includes the drainage noise reduction structure in the above-mentioned embodiment 1 and has all its technical advantages, which will not be elaborated one by one here.

[0052] It should be noted that the humidifier in this embodiment includes a base and a housing 5 arranged above the base. An ultrasonic vibrator is installed in the base, and the water mist acted by the ultrasonic vibrator enters the drainage noise reduction structure through the mist outlet 2 to achieve noise reduction processing.

[0053] During installation, the base and the shell 5 are connected together with a card-fitting structure. The two are separated first. Since the mist collecting part 4 is directly formed on the mist outlet 2, the guide column 11 is inserted into the mounting hole on the mist collecting part 4, and the height position is adjusted. Then the entire base is put together, and the guide member 1 is aligned with the mist collecting tube 6 and installed on the shell 5 to complete the entire installation process.

[0054] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
