Description

Technical Field

[0001] The utility model belongs to the technical field of air conditioning equipment design, and particularly relates to an atomizing humidifier. Background Art

[0002] A common ultrasonic atomizing humidifier turns the water in a water storage tank into water mist through the high-frequency vibration of an ultrasonic atomizing sheet by an ultrasonic atomizer. There is an air outlet pipe covering directly above the atomizing sheet, and a centrifugal fan blows air into the air outlet pipe above the ultrasonic atomizing sheet, blowing out the body with the mist and entering the room air to achieve the purpose of humidification. There are usually air outlet holes at the top of the air outlet pipe. Since the area of the air outlet holes is significantly smaller than the cross-sectional area of the air outlet pipe, the air outlet speed of the air containing mist increases and sprays out of the air outlet pipe.

[0003] The water mist column generated from the ultrasonic atomizing sheet is like a fountain, with water droplets of different diameters flying and splashing around. The water droplets splashing to the surrounding fall on the inner wall of the air outlet pipe and flow down into the water storage tank, avoiding the water droplets directly falling into the water storage tank (i.e., the water storage tray) to generate dripping noise. As Figure 6 shown in the prior art, since the air inlet is inevitably opened on the air outlet pipe, still some splashing water droplets splash out from the air inlet to generate dripping sound, and the dripping noise is much greater than the fan noise and is the main noise of the humidifier. Content of the Utility Model

[0004] Therefore, the utility model provides an atomizing humidifier, which can solve the technical problem that some splashing water droplets generated during the operation of the ultrasonic atomizing sheet of the atomizing humidifier in the prior art splash out from the air inlet on the air outlet pipe to generate dripping noise.

[0005] To solve the above problems, the utility model provides an atomizing humidifier, including a water storage tray, an atomizing device, and an air outlet pipe. The ultrasonic atomizing sheet of the atomizing device is located on the water storage tray. The bottom end cover of the air outlet pipe is arranged above the ultrasonic atomizing sheet. An air inlet is formed on the side wall of the air outlet pipe. The air inlet has a first side plate and a second side plate respectively located on the opposite sides of its width. Within the height range covered by the air inlet, on any radial cross-section of the air outlet pipe, the first side plate and the second side plate form an inner and outer layer overlapping and blocking in a diameter direction of the air outlet pipe, and an air inlet channel of the air inlet is formed between the first side plate and the second side plate.

[0006] In some embodiments, on any of the radial cross-sections, the free side edge of the first side plate protrudes along the direction away from the center of the air outlet pipe and is located radially outside the second side plate.

[0007] In some embodiments, on any of the radial cross-sections, the free side of the second side plate is recessed along the direction close to the center of the mist outlet pipe and is radially inside the first side plate.

[0008] In some embodiments, on any of the radial cross-sections, the free sides of the first side plate and the second side plate both protrude along the direction away from the center of the mist outlet pipe, and the connection position of the second side plate and the mist outlet pipe is a first point. The connection line between the first point and the center of the mist outlet pipe is a first connection line, and the extension line of the first connection line along the direction away from the center of the mist outlet pipe intersects the first side plate.

[0009] In some embodiments, the bottom side portion of the mist outlet pipe is in an inverted conical shape, and the air inlet is formed on the conical shape.

[0010] In some embodiments, a mist outlet is formed on the top side wall of the mist outlet pipe. The mist outlet extends along the circumferential direction of the mist outlet pipe and projects on any radial plane of the mist outlet pipe. The central angle corresponding to the mist outlet is not greater than 180°.

[0011] In some embodiments, the mist outlet is a strip-shaped slit, and the strip-shaped slit extends along the circumferential direction of the mist outlet pipe.

[0012] In some embodiments, the top side plate of the mist outlet extends and protrudes from the bottom side plate of the mist outlet along the side away from the center of the mist outlet pipe. The bottom side wall surface of the top side plate is an arc surface to guide the liquid droplets accumulated on the top side plate into the mist outlet pipe from top to bottom. In a top view, the mist outlet is blocked by the top side plate.

[0013] In some embodiments, the atomizing humidifier further includes a lower housing. The water storage tray is arranged on the lower housing. The lower housing is provided with a ventilation opening penetrating inside and outside it. A humidity sensor is arranged inside the lower housing and the humidity sensor is at the ventilation opening.

[0014] In some embodiments, the mist outlet faces a first side, and the ventilation opening faces a second side. The first side and the second side are respectively on opposite sides of the lower housing.

[0015] The atomizing humidifier provided by the present utility model has the following beneficial effects:

[0016] The first side plate and the second side plate are respectively arranged on the left and right sides of the air inlet of the mist outlet pipe. The first side plate and the second side plate form an inner layer-by-layer shielding in a diameter direction of the mist outlet pipe, so as to effectively prevent the liquid droplets in the mist entering the mist outlet pipe from splashing to the area outside the air inlet, and further effectively prevent the dripping noise caused by the splashed liquid droplets dripping onto the liquid surface, thereby improving the user's comfort.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. The description of at least one exemplary embodiment below is actually only illustrative and in no way limits the present utility model and its application or use. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] In the description of the present utility model, it should be understood that orientation terms such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. usually indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present utility model and simplifying the description. Without contrary description, these orientation terms do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the protection scope of the present utility model; the orientation terms "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0028] For the convenience of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "above" and the like can be used here to describe the spatial positional relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation described in the figure of the device. For example, if the device in the figure is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned as "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatial relative descriptions used here.

[0029] In addition, it should be noted that the use of words such as "first", "second", etc. to limit components is only for the convenience of distinguishing the corresponding components. Without additional declaration, the above words have no special meaning. Therefore, they should not be construed as limiting the protection scope of the present utility model.

[0030] See in conjunction with Figures 1 to 6As shown, according to an embodiment of the present utility model, there is provided an atomizing humidifier, including a water storage tray 1, an atomizing device 2, a mist outlet pipe 3, and a centrifugal fan 6. An upper housing (not shown in the figure) is covered above the water storage tray 1. The ultrasonic atomizing sheet of the atomizing device 2 is located on the water storage tray 1 to atomize the water on the water storage tray 1. The bottom end opening of the mist outlet pipe 3 is covered above the ultrasonic atomizing sheet. An air inlet 31 is formed on the side wall of the mist outlet pipe 3. The airflow generated by the drive of the centrifugal fan 6 can enter the air inlet 31 to carry the water mist formed by the ultrasonic atomizing sheet and send it out of the mist outlet pipe 3. The air inlet 31 has a first side plate 311 and a second side plate 312 respectively located on the relative two sides of its width (taking the orientation of the humidifier in the use state as a reference, the width is also the Figure 1 left - right direction), and within the range of the height of the air inlet 31 (taking the orientation of the humidifier in the use state as a reference, the width is also the Figure 1 up - down direction), on any radial cross - section of the mist outlet pipe 3 (taking the orientation of the humidifier in the use state as a reference, the radial cross - section is also the horizontal cross - section), the first side plate 311 and the second side plate 312 form an inner - outer layer overlapping and shielding in a diameter direction of the mist outlet pipe 3 (such as the straight line OBA1 direction shown in Figure 3 , point O is the central projection of the mist outlet pipe 3), and an air inlet channel (not labeled in the figure) of the air inlet 31 is formed between the first side plate 311 and the second side plate 312.

[0031] In this technical solution, the first side plate 311 and the second side plate 312 are respectively arranged on the left and right sides of the air inlet 31 of the mist outlet pipe 3, so that the first side plate 311 and the second side plate 312 form an inner - layer overlapping and shielding in a diameter direction of the mist outlet pipe 3, thereby effectively preventing the liquid droplets in the mist entering the mist outlet pipe 3 from splashing out of the air inlet 31 to the area outside the mist outlet pipe 3, and further effectively preventing the dripping noise caused by the splashed liquid droplets dripping on the liquid surface, improving the user's comfort during use.

[0032] In a specific embodiment, as shown in Figure 3 , on any of the radial cross - sections, the free side of the first side plate 311 protrudes along the direction away from the center of the mist outlet pipe 3 and is located radially outside the second side plate 312; and as shown in Figure 4 , as another specific embodiment, on any of the radial cross - sections, the free side of the second side plate 312 is recessed along the direction close to the center of the mist outlet pipe 3 and is located radially inside the first side plate 311. With such a design, it is only necessary to make an extension design for either the first side plate 311 or the second side plate 312, and the structure is simple and easy to manufacture.

[0033] In another specific embodiment, specifically refer to Figure 5As shown, on any of the radial cross-sections, the free sides of the first side panel 311 and the second side panel 312 both protrude in a direction away from the center of the mist outlet pipe 3, and the connection position between the second side panel 312 and the mist outlet pipe 3 is a first point, a line connecting the first point and the center of the mist outlet pipe 3 is a first line, and the first line intersects with the first side panel 311 along an extension line away from the center of the mist outlet pipe 3.

[0034] In this technical solution, the first side plate 311 and the second side plate 312 are both designed to be structures protruding toward the outside of the mist outlet pipe 3. This design is conducive to the connection between the air outlet structures on the upper shell.

[0035] In some embodiments, the bottom portion of the mist outlet pipe 3 is in the shape of an inverted cone, that is, a structure with an increasing radius from bottom to top, and the air inlet 31 is formed in the cone to receive splashed water droplets and facilitate the droplets separated in the mist outlet pipe 3 to flow back into the water storage tray 1 along its conical wall.

[0036] See Figure 2 As shown, in some embodiments, a mist outlet 32 is formed on the top side wall of the mist outlet pipe 3, and the mist outlet 32 extends along the circumference of the mist outlet pipe 3 and is projected on any radial plane of the mist outlet pipe 3, and the central angle corresponding to the mist outlet 32 is not greater than 180°. In a specific embodiment, the mist outlet 32 is a strip-shaped slit, and the strip-shaped slit extends along the circumference of the mist outlet pipe 3.

[0037] In this technical solution, by arranging the mist outlet 32 on the top side wall of the mist outlet pipe 3 and making its corresponding central angle no greater than 180°, the mist outlet 32 is roughly formed into a semi-circular shape, which can enable the atomizing humidifier in the utility model to form a fog type with fog on one side. This fog type is conducive to placing the humidifier against the wall, saving space without wetting the wall.

[0038] See also Figure 2 As shown, the top side panel 321 of the mist outlet 32 extends along a side away from the center of the mist outlet pipe 3 and protrudes from the bottom side panel (not marked in the figure) of the mist outlet 32. The bottom side wall of the top side panel 321 is an arc surface (specifically, an arc surface protruding downward) to guide the droplets gathered on the top side panel 321 from top to bottom into the mist outlet pipe 3. In a top-down perspective (when the humidifier is in use), the mist outlet 32 is blocked by the top side panel 321.

[0039] In this technical solution, the top side plate 321 located above the strip-shaped gap is designed to have a structure with a portion protruding outside the bottom side plate, and the lower wall surface of the top side plate 321 is an arc surface, so that the water droplets formed at the mist outlet 32 can be utilized for reflux to prevent the mist outlet 32 of the strip-shaped gap from being blocked due to the surface tension of water, thereby ensuring the smooth mist output of the humidifier.

[0040] The atomizing humidifier further includes a lower housing 4, the water storage tray 1 is arranged on the lower housing 4, a ventilation opening 41 penetrating inside and outside the lower housing 4 is formed on the lower housing 4, a humidity sensor 5 is arranged inside the lower housing 4 and the humidity sensor 5 is located at the ventilation opening 41 to be able to detect the environmental humidity where the humidifier is located in real time. In a preferred embodiment, the mist outlet 32 faces the first side, the ventilation opening 41 faces the second side, and the first side and the second side are respectively located on opposite sides of the lower housing 4, which can effectively avoid the influence of the drooping mist on the humidity sensor 5, thereby ensuring the accuracy of the detection result of the humidity sensor 5.

[0041] It is easy for those skilled in the art to understand that, on the premise of no conflict, the advantageous technical features of the above various methods can be freely combined and superimposed.

[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention. The above is only the preferred implementation manner of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
