DETAILED DESCRIPTION

[0020] In order to make the above objects, features and advantages of the present application more obvious and understandable, the specific embodiments of the present application will be described in detail below with reference to the drawings. In the following description, a large number of specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0021] The "upper" and "lower" directions in the present application are described in the normal state of the humidifier.

[0022] The utility model discloses a kind of anti-toppling overflow top covers, specifically, please combine Figures 1-5 The anti-toppling overflow top cover of the embodiment includes: a top cover body 100 and a top cover upper cover 200 mounted on the top cover body 100, the bottom of the top cover body 100 has a mist pipe 210 integrally formed with the top cover body 100, the mist pipe 210 is communicated with the mist device of the humidifier to which the anti-toppling overflow top cover of the utility model is mounted, and a plurality of vertical ribs 212 are arranged on the inner wall of the mist pipe 210 along the circumference thereof at intervals. The lower part of the side of the rib 212 facing the center of the mist pipe 210 is convex to form a step 2121, and a floating ball 211 is movably arranged on the step 2121. The density of the floating ball 211 is less than that of water. A curved first groove 200a is arranged on the lower surface of the top cover upper cover 200 at a position corresponding to the mist pipe 210. The groove wall and groove bottom of the first groove 200a are smooth curved surfaces with the same shape as the surface of the floating ball 211. The groove bottom of the first groove 200a is provided with a mist outlet hole 200b with a diameter smaller than that of the floating ball 211. When the humidifier is working normally, the surface of the floating ball 211, the side of the rib 212, and the inner wall of the mist pipe 210 together form a mist outlet channel, and the water mist is sprayed out of the mist outlet hole 200b through the mist outlet channel. The side of the rib 212 facing the floating ball 211 is a first plane 212a, which is an inclined plane with a certain inclination angle and inclined outward. When the humidifier is tilted, the water enters the mist pipe 210, the floating ball 211 is moved to the first groove 200a of the top cover upper cover 200 under the action of the water flow and the restriction of the first plane 212a, and finally reaches the first groove 200a, tightly fits with the curved surface in the first groove 200a, and closes the mist outlet hole 200b, so that the water in the mist pipe 210 cannot flow out, and the function of preventing the humidifier from toppling and overflowing is realized.

[0023] In order to make the floating ball 211 reach the first groove 200a of the top cover upper cover 200 more smoothly and close the mist outlet hole 200b when the humidifier is tilted, in an embodiment, as Figure 3As shown, the draft angle of the inclined surface of the rib 212 facing the floating ball 211 is 2° (i.e. the slope is 1:28.64). In addition, the first plane 212a of the rib 212 facing the floating ball 211 and the curved surface of the first groove 200a are also smoothly transitioned, so that the floating ball 211 can move along the slope of the first plane 212a to the first groove 200a when it is lifted upward by the buoyancy of water, and the rib 212 is prevented from being stuck at the transition between the curved surface of the first groove 200a and the first plane 212a, thereby improving the speed and reliability of closing the mist outlet hole 200b when the humidifier is tilted.

[0024] During the use of the humidifier, condensate water often appears around the mist outlet hole 200b of the humidifier, leaving water stains on the surface of the humidifier or flowing down to wet the table or floor, which seriously affects the appearance. In order to reduce the influence of condensate water at the mist outlet hole 200b of the top cover 200 on the appearance of the humidifier, in an embodiment, as shown in Figures 1-5 the upper surface of the top cover 200 around the area of the mist outlet hole 200b is recessed downward to form a condensation groove 200c, so that the condensate water along the edge of the mist outlet hole 200b flows downward into the condensation groove 200c, realizing the unified collection of condensate water at the mist outlet hole 200b, basically eliminating the possibility of condensate water leaving water stains on other surfaces of the humidifier, and avoiding other influences caused by condensate water flowing to the floor or table.

[0025] During the use of the humidifier, a part of the water in the water mist is released into the air to adjust the air humidity, and another part is condensed at the mist outlet hole 200b and cannot be effectively utilized, which not only causes waste but also increases the frequency of water injection into the humidifier. In order to improve the utilization rate of water in the water tank, on the basis of the previous embodiment, as shown in Figure 1 a one-way valve 220 is further arranged at the groove bottom of the condensation groove 200c. In this embodiment, the one-way valve 220 is a one-way duckbill valve. The one-way duckbill valve is in communication with the water tank of the humidifier. The condensate water of the mist outlet hole 200b flows down along the groove wall of the condensation groove 200c and converges at the groove bottom of the condensation groove 200c, and then flows into the water tank of the humidifier through the one-way duckbill valve, realizing the recycling of the condensate water, improving the utilization rate of water in the water tank, reducing the frequency of water injection into the humidifier, and also reducing the trouble of frequent cleaning of the condensate water in the condensation groove 200c.

[0026] In order to speed up the flow of condensate water in the condensation groove 200c into the water tank through the one-way valve 220, on the basis of the previous embodiment, as shown in Figure 1As shown, the groove bottom of the condensation groove 200c is provided with a slope having a lowest point, and the one-way valve 220 is arranged at the position of the lowest point. In this embodiment, the condensation groove 200c is a sector around the mist outlet hole 200b, and the point on the symmetric axis of the sector-shaped condensation groove 200c groove bottom closest to the mist outlet hole 200b is taken as the lowest point of the condensation groove 200c groove bottom, that is, the middle of the condensation groove 200c groove bottom is low and the two sides are high. In this way, the condensate water at both ends of the condensation groove 200c can also quickly collect at the one-way valve 220, and then flow into the water tank of the humidifier through the one-way valve 220, effectively accelerating the recycling of the condensate water and increasing the ease of use of the humidifier.

[0027] In order to facilitate disassembly, removal, and anti-toppling and overflow of the water top cover, in an embodiment, as shown in Figures 1-5 A handle 230 is protruded on the upper surface of the top cover 200. During daily use of the humidifier, a large amount of scale is left on the mist outlet hole 200b, the mist outlet pipe 210, the condensation groove 200c, and other components, which not only causes blockage of the pipeline or the one-way valve to affect use, but also breeds bacteria to easily cause diseases, so the anti-toppling and overflow water top cover needs to be regularly disassembled for cleaning and disinfection. However, in order to make the humidifier visually beautiful, the top cover of the humidifier is often designed to have a smooth transition with the humidifier body, so it is extremely inconvenient to disassemble and remove the top cover of the humidifier. Therefore, in this embodiment, the handle 230 is arranged on the top cover 200, and the handle 230 is a columnar body capable of achieving lifting and rotating of the anti-toppling and overflow water top cover, facilitating disassembly and removal of the anti-toppling and overflow water top cover, and providing convenience for daily cleaning and maintenance work.

[0028] On the basis of the previous embodiment, as shown in Figures 1-5 The handle 230 arranged on the top cover 200 is a columnar body with an open upper portion and an internal hollow, and a handle cover 231 is detachably connected to the open upper portion of the handle columnar body. In order to reduce the weight of the anti-toppling and overflow water top cover while having a certain strength, the handle 230 is designed to be hollow. In addition, in order to avoid dust deposition inside the handle 230 and improve the strength when the handle is gripped, a handle cover 230 is installed at the open upper portion. In this way, the convenience of disassembly and removal of the anti-toppling and overflow water top cover is ensured, and the weight of the anti-toppling and overflow water top cover is reduced, so that the center of gravity of the humidifier is lowered, the overall stability of the humidifier is improved, and the risk of toppling is reduced.

[0029] In order to improve the sealing between the anti-toppling and overflow water top cover and the humidifier body, in an embodiment, as shown in Figure 1As shown in the drawings, a sealing ring 300 is sleeved at the bottom of the top cover body 100, and a silica gel sealing ring is selected in the embodiment. When the humidifier is working, there is a temperature difference between the anti-toppling and water-overflowing top cover and the humidifier body, so that a gap is generated at the connection position due to the temperature difference, which reduces the air tightness of the humidifier, reduces the spraying efficiency of the mist outlet hole 200b, and has the risk of water mist spraying from the gap, which is easy to cause damage to the connection position for a long time. The sealing ring 300 sleeved at the bottom of the anti-toppling and water-overflowing top cover can effectively block the gap generated at the connection position due to the temperature difference, increase the air tightness of the humidifier, and improve the spraying efficiency of the mist outlet hole 200b of the humidifier and the durability of the humidifier body.

[0030] In an embodiment, as shown in the drawings, Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown in the drawings, a stainless steel disc 400 is arranged at the bottom of the top cover body 100 in a spaced manner, the stainless steel disc 400 is detachably connected at the bottom of the top cover body 100, and a plurality of air holes 400a are formed in the disc surface of the stainless steel disc 400. Due to the design of the humidifier mist generating device, when the water mist generating device generates water mist, the water mist is easily concentrated and sprayed on a point at the bottom of the anti-toppling and water-overflowing top cover of the humidifier, which causes the temperature of the point to be significantly higher than that of other areas, and causes the material of the area where the point is located to be accelerated aging. After the stainless steel disc 400 is installed, the water mist is first sprayed on the stainless steel disc 400, and then dispersed through the air holes 400a of the stainless steel disc. In addition, the stainless steel disc 400 has good heat conductivity, which can make the water mist pass through different air holes 400a at the same temperature, reduce the temperature difference between different areas at the bottom of the top cover body 100, and effectively prolong the service life of the humidifier.

In order to make the description simple, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not exist, they should be considered as the scope of the description.

[0032] The above-described embodiments only express several implementation manners of the utility model, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the utility model patent. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, which belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
