Description

Technical Field

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

[0002] The common ultrasonic atomizing humidifier is an ultrasonic atomizer that turns water into water mist through the high-frequency vibration of the ultrasonic atomizing plate, and the fan blows the water mist out of the body and into the room air to achieve the purpose of humidification. Its wind system generally uses a centrifugal fan to blow wind and mist into the mist outlet pipe above the ultrasonic atomizing plate. There is a small hole on the top of the mist outlet pipe. Since the area of ​​the small hole is significantly smaller than the cross-sectional area of ​​the mist outlet pipe, the speed of the wind containing the mist is increased and sprayed out of the mist outlet pipe. The wind generated by the centrifugal fan generally enters the mist outlet pipe from the gap between the bottom of the mist outlet pipe and the water surface or the gap on the cylindrical surface of the mist outlet pipe.

[0003] The water mist column generated by the ultrasonic atomizer is like a fountain, with water droplets of different diameters flying. In order to prevent large particle droplets from being blown out of the mist outlet pipe and wetting the nearby ground, the mist outlet pipe in the prior art generally has a water retaining design, but the effect of this water retaining structure in separating droplets is poor, and the phenomenon of larger particle size droplets wetting the ground (desktop) after being blown out of the mist outlet pipe is still quite significant. Utility Model Content

[0004] Therefore, the utility model provides an atomizing humidifier, which can solve the technical problem in the prior art that the mist blown out by the mist outlet pipe of the atomizing humidifier contains a large number of large particle droplets, resulting in a serious wetting phenomenon of the ground or the table.

[0005] In order to solve the above problems, the utility model provides an atomizing humidifier, comprising a water storage tray, an upper shell body covered on the water storage tray, a cavity formed between the upper shell body and the water storage tray, the atomizing humidifier also includes a mist outlet pipe, the mist outlet pipe has an outer pipe section outside the cavity and an inner pipe section inside the cavity, the bottom end of the inner pipe section has a mist inlet, the side wall of the tube body of the inner pipe section has an airflow guide portion, the airflow guide portion includes a first vertical wall and a second vertical wall arranged at intervals, an airflow introduction channel is formed between the first vertical wall and the second vertical wall, and the wall surface of the first vertical wall facing the second vertical wall is tangent to the inner wall surface of the tube body of the inner pipe section.

[0007] The atomizing humidifier also includes a fan arranged on the water storage tray, the fan has an air supply port, and an air duct cover is also formed on the inner wall surface of the upper shell. When the upper shell and the water storage tray are assembled, the air supply port is located in the covering space of the air duct cover, the air duct cover has an air outlet, and the inlet of the air flow introduction channel is connected to the air outlet.

[0008] In some embodiments, the top surface of the horizontal wall becomes lower in height as it approaches the interior of the inner pipe section.

[0009] In some embodiments, the inner pipe section includes an inner fixed cylinder section integrally formed with the upper shell body and a lower mist guide cylinder detachably connected to the inner fixed cylinder section, the mist inlet is formed at the free end of the lower mist guide cylinder, and the airflow guide portion is formed on the lower mist guide cylinder; and / or, when the atomizing humidifier is in normal operating state, the bottom end surface of the air duct cover is below the liquid level of the water stored in the water storage tray.

[0010] In some embodiments, the lower mist guide cylinder is a tapered structure with a cross-sectional area gradually decreasing from top to bottom.

[0011] In some embodiments, a swirl blade is provided in the mist outlet pipe and fixed in the outer pipe section. The rotation direction of the mist formed by the blade deflection angle of the swirl blade is the same as the rotation direction of the airflow guided by the airflow guide part.

[0012] In some embodiments, the top end of the outer tube section has a mist outlet, and the flow cross-sectional area of ​​the mist outlet first decreases and then increases along the direction in which the mist flows out.

[0015] In some embodiments, the upper mist guide cylinder is detachably connected to the outer fixed cylinder section via a corner sleeve; and / or,

[0016] The atomizing humidifier further comprises a humidity probe arranged in a first side area of ​​the upper shell, the upper mist guide cylinder is located in a second side area of ​​the upper shell, and the first side area and the second side area are two opposite areas of the upper shell.

[0017] The utility model provides an atomizing humidifier with the following beneficial effects:

[0018] Since the wall surface of the first vertical wall facing the second vertical wall is tangent to the inner wall surface of the tube body of the inner tube section, the airflow (i.e. wind) in the cavity is driven to enter the inner tube section along the tangential direction through the airflow introduction channel, and rotates upward along the inner wall of the tube in the mist outlet pipe to make a swirling motion, thereby causing large particle droplets entrained in the airflow to rotate and separate, and the separated droplets flow back downward along the inner wall of the mist outlet pipe, thereby further reducing the content of large particle droplets in the mist blown out of the mist outlet pipe, and further reducing the frequency of the phenomenon that the mist wets the ground or the table top.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0031] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0032] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0033] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0034] See also Figures 1 to 8 As shown, according to an embodiment of the utility model, an atomizing humidifier is provided, comprising a water storage tray 1, an upper shell 2 covered on the water storage tray 1, an atomizing device 3 arranged on the water storage tray 1, and a lower shell 9 assembled under the water storage tray 1, wherein a receiving cavity is formed between the lower shell 9 and the water storage tray 1, and corresponding electrical components, such as a control panel of the atomizing device 3, are assembled in the receiving cavity, and a cavity 20 is formed between the upper shell 2 and the water storage tray 1. The cavity 20 serves as a space for accommodating water on one hand, and its top space is also used as a mist storage space. A corresponding air inlet (not marked in the figure) is also formed on the upper shell 2, and the atomizing device 3 is used to atomize the water stored on the water storage tray 1. The atomizing device 3 can be specifically an ultrasonic atomizing sheet. The atomizing humidifier also includes a mist outlet pipe 4, which has an outer pipe section (not labeled in the figure) outside the cavity 20 and an inner pipe section (not labeled in the figure) inside the cavity 20. The bottom end of the inner pipe section has a mist inlet 41, and the top end of the outer pipe section has a mist outlet 42. The mist inlet 41 is located in the upper area of ​​the atomizing working surface of the atomizing device 3. When the atomizing device 3 is working, the water mist column and mist generated by its vibration will at least partially enter the mist outlet pipe 4 through the mist inlet 41 and be sent to the humidification space from the top mist outlet 42. The side wall of the tube body of the inner pipe section has an airflow guide 5, see Figure 5 As shown, the airflow guiding portion 5 includes a first vertical wall 51 and a second vertical wall 52 which are spaced apart, an airflow introduction channel 53 is formed between the first vertical wall 51 and the second vertical wall 52, and the wall surface of the first vertical wall 51 facing the second vertical wall 52 is tangent to the inner wall surface of the tube body of the inner tube section. Specifically, the aforementioned tangency means that on any cross section of the inner tube section, the contour of the inner wall surface of the inner tube section is a circle, while the wall surface of the first vertical wall 51 facing the second vertical wall 52 is a straight line, and the straight line is tangent to the circle.

[0035] In this technical solution, since the wall surface of the first vertical wall 51 facing the second vertical wall 52 is tangent to the inner wall surface of the tube body of the inner tube section, the airflow (i.e., wind) in the cavity 20 is driven to enter the inner tube section along the tangential direction through the airflow introduction channel 53, and rotates upward along the inner wall of the tube in the mist outlet pipe 4 to make a swirling motion, thereby enabling the large particle droplets entrained in the airflow to rotate and separate, and the separated droplets flow back downward along the inner wall of the mist outlet pipe 4, thereby further reducing the content of large particle droplets in the mist blown out by the mist outlet pipe 4, and further reducing the frequency of the phenomenon of the mist wetting the ground or the table top.

[0036] Continue to see Figure 5 As shown, in some embodiments, a horizontal wall 54 is provided between the first vertical wall 51 and the second vertical wall 52, and the air flow introduction channel 53 is located in the upper area of ​​the horizontal wall 54. By providing the horizontal wall 54 at the bottom position of the air flow introduction channel 53, which usually extends a certain length in the horizontal direction, it is possible to prevent the water mist column formed by the atomization device 3 from entering the mist outlet pipe 4 and then flowing out through the air flow introduction channel 53 and falling onto the water surface of the water storage tray 1 to generate a dripping sound, thereby reducing the noise during the use of the humidifier.

[0037] In a preferred embodiment, the top surface of the horizontal wall 54 becomes lower and lower in height as it approaches the inside of the inner tube section, so that when the water droplets formed by the atomizing device 3 flow out of the mist outlet pipe 4 through the aforementioned air flow introduction channel 53, they will flow back to the atomizing working surface of the atomizing device 3 under the guidance of the horizontal wall 54.

[0038] See Figure 2 As shown, the atomizing humidifier also includes a fan 6 arranged on the water storage tray 1, and the fan 6 can specifically be a centrifugal fan. The fan 6 has an air supply port 61, and an air duct cover body 21 is also formed on the inner wall surface of the upper shell 2. When the upper shell 2 and the water storage tray 1 are assembled, the air supply port 61 is located in the cover space of the air duct cover body 21, and the air duct cover body 21 has an air outlet (not marked in the figure), and the inlet of the air flow introduction channel 53 is connected to the air outlet.

[0039] In this technical solution, an air duct cover 21 is provided on the upper shell body 2. After the upper shell body 2 is assembled with the water storage tray 1, the air duct cover 21 is provided outside the air supply port 61 of the fan 6, thereby forming a relatively small static pressure chamber in the air duct cover 21. The wind delivered from the air supply port 61 smoothly enters the air flow introduction channel 53 connected thereto through the air outlet of the air duct cover 21, thereby reducing the loss of wind pressure.

[0040] See also Figure 3As shown, the aforementioned air duct cover body 21 can be a continuous thin-walled shell structure with a bottom opening, and has two walls on both sides of its air outlet position, which correspond to the aforementioned first vertical wall 51 and second vertical wall 52 respectively and are located on the outside of the two, thereby forming a sealed connection between the air outlet of the air duct cover body 21 and the airflow introduction channel 53.

[0041] When the atomizing humidifier is in normal operation, the bottom end surface of the air duct cover 21 is below the liquid level of the water stored in the water storage tray 1. Such a design can ensure that the airflow in the air duct cover 21 is smoothly guided into the mist outlet pipe 4.

[0042] In some embodiments, the inner tube section includes an inner fixed cylinder section (not marked in the figure) integrally formed with the upper shell body 2 and a lower mist guide cylinder 43 detachably connected to the inner fixed cylinder section, the mist inlet 41 is formed at the free end of the lower mist guide cylinder 43, and the airflow guide portion 5 is formed on the lower mist guide cylinder 43. In this technical solution, the lower mist guide cylinder 43 is designed as an independent component that can be detachably connected to the inner fixed cylinder section, which facilitates the mold manufacturing of the component.

[0043] In some embodiments, the lower mist guide tube 43 is a conical structure with a gradually decreasing cross-sectional area from top to bottom, that is, the lower mist guide tube 43 is generally in the shape of a cone with a larger top and a smaller bottom. Large water droplets falling from the water mist column generated by the atomizing device 3 are caught by the cone surface and directed to the water surface, preventing these large water droplets from falling directly to the water surface and generating noise.

[0044] See Figure 6 As shown, in some embodiments, a swirl blade 71 is provided in the mist outlet pipe 4, and the swirl blade 71 is fixed in the outer pipe section, that is, the position of the swirl blade 71 is fixed and will not be driven to rotate by the mist outlet airflow. The rotation direction of the mist formed by the blade deflection angle of the swirl blade 71 is the same as the rotation direction of the airflow guided by the airflow guide part 5. The airflow passes through the swirl blade 71 to accelerate the rotation and direction change of the airflow, which can further separate large droplets in the airflow.

[0045] In some embodiments, the top of the outer tube section has a mist outlet 42, and the flow cross-sectional area of ​​the mist outlet 42 first decreases and then increases along the direction of the mist outflow, that is, the flow cross-sectional area first decreases and then gradually expands. The cross-sectional area contraction section increases the velocity of the mist outflow, and the rotation of the composite airflow can further enhance the centrifugal separation of the droplets. The cross-sectional area expansion section makes the large droplets produced by centrifugal separation lose kinetic energy and cannot fly out of the mist outlet 42. At the same time, the cross-sectional area expansion section can also prevent the large droplets produced by centrifugal separation from gathering and blocking the mist outlet 42. It should be noted that the mist outlet 42 is usually an annular gap, and the width of the annular gap is generally 1-2 mm. Due to the surface tension, the water droplets will connect the inner and outer circles of the annular gap, thereby blocking the gap. In this technical solution, the cross-sectional area expansion makes the annular gap wider and not easily blocked by large water droplets.

[0046] In some embodiments, Figure 7 As shown, a central column 72 is provided inside the mist outlet 42, and the top of the central column 72 is connected to the inner wall of the mist outlet 42 via a connecting rib 73, and the swirl blade 71 is mounted on the bottom end of the central column 72. The swirl blade 71 can be mounted on the bottom end of the central column 72 by, for example, an interference fit or a snap-on connection.

[0047] In some embodiments, the outer pipe section includes an outer fixed cylinder section (not marked in the figure) integrally formed with the upper shell body 2 and an upper mist guide cylinder 44 detachably connected to the outer fixed cylinder section, the mist outlet 42 is formed at the free end of the upper mist guide cylinder 44, and the orientation of the upper mist guide cylinder 44 can be adjusted, so that the humidification area can be adjusted by adjusting the deflection direction of the upper mist guide cylinder 44.

[0048] See Figure 8 As shown, in some embodiments, the upper mist guide cylinder 44 is detachably connected to the outer fixed cylinder section via a corner sleeve 45 .

[0049] The atomizing humidifier further includes a humidity probe 8 disposed in a first side area of ​​the upper shell 2, the humidity probe 8 is used to detect humidity so that the humidifier can perform constant humidity control, the upper mist guide cylinder 44 is located in a second side area of ​​the upper shell 2, the first side area and the second side area are two opposite areas of the upper shell 2, Figure 8 The orientation shown is for reference only. The first side area is the left side area of ​​the humidifier, and the second side area is the right side area of ​​the humidifier. In this way, the humidity probe 8 is away from the area covered by the fog sinking (that is, the right side area), thereby avoiding the humidity detected by the humidity probe 8 being too high, deviating too much from the actual humidity in the room, and making the constant humidity control ineffective.

[0050] It is easy for those skilled in the art to understand that, without conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.

[0051] The above is only a preferred embodiment of the utility model, and is not intended to limit the utility model. Any modifications, equivalent replacements and improvements made within the spirit and principles of the utility model should be included in the protection scope of the utility model. The above is only a preferred implementation of the utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the utility model, and these improvements and variations should also be regarded as the protection scope of the utility model.
