Abstract
Description
Technical Field
[0001] This utility model relates to the field of humidifier technology, specifically to an air outlet structure for a humidifier. Background Technology
[0002] The main function of a humidifier is to increase the humidity in the air by spraying water mist through its vent. Different types of humidifiers have different designs and locations for their vents. For example, some humidifiers have their vents on the side, while others have them on the top or bottom.
[0003] The air outlet structure of existing humidifiers usually does not have any anti-fog structure. When water mist is continuously sprayed out of the air outlet, the water mist comes into contact with the top cover at the air outlet. Since the top cover is made of plastic, water mist can easily accumulate on the top cover, which causes inconvenience to use. Currently, there is a lack of an air outlet structure that can automatically handle the accumulated water and make the accumulated water automatically flow back into the humidifier. Utility Model Content
[0004] The purpose of this utility model is to provide an air outlet structure for a humidifier that overcomes the problem of water accumulating at the top cover in the prior art, and can automatically collect the water and allow it to flow back into the humidifier.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an air outlet structure for a humidifier, including a top cover plate, the top cover plate including a plate body, a water mist outlet penetrating both sides of the plate body, a lower air outlet assembly and an upper air outlet assembly disposed within the water mist outlet, a plurality of guide needles disposed at the bottom of the lower air outlet assembly, and the lower air outlet assembly including a plurality of coaxially designed lower water-blocking ribs, the plurality of lower water-blocking ribs being fixed together by a plurality of first fixing strips, the plurality of first fixing strips being distributed in the circumferential direction of the lower water-blocking ribs. The upper vent assembly includes multiple coaxial upper venting ribs, which are fixed together by multiple second fixing strips distributed along the circumference of the upper venting ribs. The upper venting ribs have a first central vent outlet at their center, and adjacent upper venting ribs are fixed together by multiple net sheets, each net sheet having multiple upper vent microholes.
[0006] Preferably, multiple fixing piles are fixed on the lower end face of the plate, and the multiple fixing piles are distributed on both sides of the plate.
[0007] Preferably, a guide wall is provided inside the water mist outlet, the guide wall is inclined, and the inclination angle of the guide wall is between 75° and 85°.
[0008] Preferably, both the first fixing strip and the second fixing strip are horizontally arranged, and both the first fixing strip and the second fixing strip are fixed to the plate body.
[0009] Preferably, the second central air outlet is located above the first central air outlet, and the inner diameter of the second central air outlet is smaller than the inner diameter of the first fixing strip.
[0010] Preferably, the upper air outlet assembly also includes multiple sealing plates, which are disposed on the outside of the upper water-blocking ribs and are all fixed to the plate body.
[0011] Preferably, the multiple lower water-blocking ribs and the multiple upper water-blocking ribs are arranged to cross each other in the vertical direction, and the multiple lower water-blocking ribs and the multiple upper water-blocking ribs are all arranged horizontally.
[0012] Preferably, the multiple guide pins are all vertically arranged, and the multiple guide pins are respectively fixed to the bottom of multiple lower water-blocking ribs.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model, by setting multiple rings of lower and upper water-blocking ribs, combined with several sets of cross-distributed lower and upper mesh sheets, can intercept water mist and prevent water mist from gushing out in a short time. The water mist can be dispersed and sprayed out slowly through the lower and upper micro air outlets. Therefore, it can not only avoid water accumulation at the air outlet, but also not affect the spraying effect of water mist.
[0015] 2. In this utility model, the water-blocking ribs and mesh are both made of metal. When water mist comes into contact with them, it will condense and then flow back into the humidifier through several guide needles. This effectively avoids the problem of water accumulation at the top of the water mist outlet, and the condensed water will not spread to the surroundings, but will flow back into the humidifier, eliminating the trouble of manual cleaning.

[0026] Please see Figure 1 This utility model provides an embodiment for a humidifier with the water outlet located at the top: a humidifier air outlet structure, including a humidifier top cover plate 1.
[0027] Please see Figure 2 The humidifier top cover 1 includes a plate body 11. Multiple fixing posts 12 are fixed on the lower end face of the plate body 11. The multiple fixing posts 12 are distributed on both sides of the plate body 11. The multiple fixing posts 12 are used to correspond to the corresponding openings on the humidifier. By snapping the fixing posts 12 into the openings, the plate body 11 can be fixed to the top of the humidifier. A water mist outlet 111 is provided on the plate body 11, penetrating both sides. A lower air outlet assembly 13 is provided in the water mist outlet 111. A number of guide needles 15 are provided at the bottom of the lower air outlet assembly 13.
[0028] Please see Figure 3 An upper air outlet assembly 14 is also provided inside the water mist outlet 111. The upper air outlet assembly 14 is located above the lower air outlet assembly 13. The upper air outlet assembly 14 includes multiple coaxially designed upper water-blocking ribs 141. The multiple upper water-blocking ribs 141 are fixed together by multiple second fixing strips 142. The multiple second fixing strips 142 are distributed in the circumferential direction of the upper water-blocking ribs 141. A second central air outlet 143 is provided at the center of the upper water-blocking ribs 141. Adjacent upper water-blocking ribs 141 are fixed together by multiple mesh sheets 144. Each upper... The mesh 144 is provided with multiple upper air outlet micro-holes 145. The upper air outlet assembly 14 also includes multiple sealing plates 146. The multiple sealing plates 146 are located on the outside of the upper water-blocking ribs 141, and the multiple sealing plates 146 are fixed to the plate body 11. The multiple sealing plates 146 are used to seal the outermost opening of the upper water-blocking ribs 141 to prevent water mist from gushing out in large quantities and causing water accumulation on the upper surface of the plate body 11. Each sealing plate 146 is provided with a slender water guide hole 147, which is used to guide the water accumulated on the sealing plate 146 downward.
[0029] Please see Figure 4The water mist outlet 111 is provided with a guide wall 112, which is inclined at an angle between 75° and 85°. The guide wall 112 is designed to better allow excess water mist to flow back into the humidifier. The lower air outlet assembly 13 includes multiple coaxially designed lower water-blocking ribs 131, which are fixed together by multiple first fixing strips 132. A first central air outlet 133 is located at the center of each lower water-blocking rib 131. Both the first fixing strips 132 and the second fixing strips 142 are horizontally arranged and fixed to the plate 11. This allows the first fixing strips 132 to support the lower water-blocking ribs 131, and the second fixing strips 142 to support the upper water-blocking ribs 141. The second central air outlet... 143 is located above the first central air outlet 133, and the inner diameter of the second central air outlet 143 is smaller than the inner diameter of the first fixing strip 132. When the water mist passes through the first central air outlet 133 and then crosses the second central air outlet 143, its opening decreases, causing the water mist to pass through at a slower rate, further reducing the possibility of water mist accumulating into water droplets on the upper surface of the plate 11. Multiple lower water-blocking ribs 131 and multiple upper water-blocking ribs 141 are arranged in a vertical direction, and both the multiple lower water-blocking ribs 131 and the multiple upper water-blocking ribs 141 are arranged horizontally. Therefore, the lower mesh 134 and the upper mesh 144 are distributed in a vertical direction, which helps to disperse the water mist more effectively and further reduces the probability of water accumulation. Several guide needles 15 are all arranged vertically, and several guide needles 15 are respectively fixed to the bottom of multiple lower water-blocking ribs 131.
[0030] Please see Figures 5 to 6 Multiple first fixing strips 132 are distributed in the circumferential direction of the lower water-blocking rib 131. The lower water-blocking rib 131, the lower mesh 134, the upper water-blocking rib 141 and the mesh 144 are all made of metal. Two adjacent lower water-blocking ribs 131 are fixed together by multiple lower mesh 134. Each lower mesh 134 is provided with multiple lower air outlet microholes 135.
[0031] Please refer to the following: Figures 1 to 6In the operation of this invention, the humidifier sprays water mist into the interior of the water mist outlet 111. After passing through the first central air outlet 133 and multiple lower air outlet micro-holes 135, the water mist rises and is then sprayed out through the second central air outlet 143 and multiple upper air outlet micro-holes 145. As the water mist passes through the first central air outlet 133 and then upwards through the second central air outlet 143, the opening of the second central air outlet 143 is smaller than that of the first central air outlet 133, thus slowing down the flow rate of the water mist. The probability of water accumulation on the upper part of the plate 11 is reduced. The vertical cross design of the lower air outlet micro-hole 135 and the upper air outlet micro-hole 145 also slows down the water mist passage rate, thus further reducing the probability of water accumulation. After the water mist comes into contact with the lower water-blocking rib 131, the lower mesh 134, the upper water-blocking rib 141 and the mesh 144, it will condense to a certain extent and produce water droplets. Then, it will flow back into the humidifier through several guide needles 15 and be reused. Therefore, the problem of water accumulation can be largely avoided.
[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
