[0002] With the improvement of living standards, people are paying more and more attention to their own health. In order to improve the indoor air quality, various air purifier products have appeared on the market. In addition to the dust removal and sterilization functions, some of these air purifiers also have humidification functions, that is, adding a humidification device to the air purifier, which can safely and quickly filter out pollutants in the air while keeping the air at the most suitable humidity.

[0003] At present, the air purifier humidifiers on the market usually humidify in the following way: a water pump is set in the water tank, and after the water pump is started, water is pumped to the top of the humidification core through the pipeline, so that the water is scattered to the upper end of the humidification core through the fine holes distributed in the upper cover of the humidification core, and the water flows from top to bottom along the humidification core to moisten the humidification core. When the wind blown by the wind wheel passes through the moist humidification core, it will bring moisture into the indoor space environment, thereby playing a role in increasing the humidity of the indoor space. The above structure has high requirements for the water pressure of the water pump, and the water spraying efficiency is low, which affects the user experience. Utility Model Content

[0037] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] In the related art, the air purifier humidifiers on the market usually humidify in the following way: a water pump is set in the water tank, and after the water pump is started, water is pumped to the top of the humidification core through the pipeline, so that the water is scattered to the upper end of the humidification core through the fine holes distributed in the upper cover of the humidification core, and the water flows from top to bottom along the humidification core to moisten the humidification core. When the wind blown by the wind wheel passes through the moistened humidification core, it will bring moisture into the environment of the indoor space, thereby playing a role in increasing the humidity of the indoor space. The above structure has high requirements for the water pressure of the water pump, and the water spraying efficiency is low, which affects the user experience.

[0039] In view of this, an embodiment of the present application proposes a rotary spray humidification structure.

[0040] See also Figure 1 and Figure 2 A rotary spray humidification structure comprises a body, a water tank arranged inside the body, a humidification core 1 and a spray assembly 2. A support column 3 is axially arranged at the center of the humidification core 1, and a hollow first water supply channel 4 is formed inside the support column 3; the spray assembly 2 comprises a nozzle 21, which is coaxially arranged at the top of the support column 3 and can rotate relative to the support column 3, and a water spray channel 6 is arranged in the nozzle 21, the water inlet end of the water spray channel 6 is connected with the water outlet end of the first water supply channel 4, and the water outlet end port of the water spray channel 6 is arranged away from the axis of the water inlet end port of the water spray channel 6; a water pump is arranged in the water tank, and the output end of the water pump is connected with the water inlet end of the first water supply channel 4 through a pipeline.

[0041] Specifically, the rotary spray humidification structure includes a body, and a water tank, a purification component, a humidification component and a spray component 2 are arranged in sequence from bottom to top inside the body. Among them, the water tank is used to provide the machine with water for spray humidification, and a water pump is arranged in the water tank to provide power for the transportation of water flow; the purification component includes a filter screen, which can filter and purify dust and foreign particles in the inhaled air; the humidification component includes a humidification core 1, and the wet humidification core 1 can humidify the filtered air; the spray component 2 includes a nozzle 21, which is used to spray and moisten the humidification core 1.

[0042] The humidifying core 1 adopts a cylindrical structure, and a support column 3 is arranged at the axis center of the humidifying core 1. The interior of the support column 3 is hollow to form a first water supply channel 4. The lower end of the support column 3 is connected to the output end of the water pump through a pipe, and the top of the support column 3 is connected to the nozzle 21; the nozzle 21 is coaxial with the support column 3, and the nozzle 21 is rotatably installed on the top of the support column 3, and has a water spray channel 6 inside, which is connected to the first water supply channel 4. Therefore, when the water pump is turned on, the water in the water tank can enter the first water supply channel 4 from bottom to top through the pipe, and then enter the water spray channel 6, and finally spray out from the water outlet end of the water spray channel 6.

[0043] See also Figure 2 The water spray channel 6 is an eccentric structure. Specifically, the axis of the nozzle 21 and the axis of the water inlet port of the water spray channel 6 are the same as the axis of the first water supply channel 4, and the axis of the water outlet port of the water spray channel 6 deviates from the axis of the first water supply channel 4. The eccentric water channel structure makes the water flow in the nozzle 21 present an asymmetric distribution, thereby generating a large rotational momentum. On the one hand, it can drive the nozzle 21 to rotate around its axis, so that the sprayed water line continuously changes the water outlet direction as the nozzle 21 rotates, covering the upper end of the humidification core 1 360 degrees in all directions, thereby improving the uniformity of the spray and the humidification efficiency; on the other hand, it can enhance the speed and pressure of the water flow when it is sprayed. Therefore, under the premise of ensuring the same spraying effect, the water pressure requirement for the water pump can be effectively reduced.

[0044] Optionally, a water spraying groove 211 is provided in the spray head 21 , the water spraying channel 6 is formed inside the water spraying groove 211 , and the bottom surface of the water spraying groove 211 is set as an arc surface.

[0045] See also Figure 3 The water spray channel 6 is formed by opening a water spray groove 211 inside the nozzle 21. The water spray groove 211 includes two opposite groove sides and a groove bottom surface. Since the water spray channel 6 is an eccentric water channel structure, there is an angle between the water inlet direction and the water outlet direction of the water spray groove 211. The groove bottom surface of the water spray groove 211 is set as an arc surface, which can make the transition between the water inlet end and the water outlet end of the water spray groove 211 smooth, which is conducive to reducing water flow resistance and reducing the scouring of the groove bottom surface by water flow.

[0046] Optionally, the size of the water outlet port of the water spray channel 6 is smaller than the size of the water inlet port of the water spray channel 6 .

[0047] Specifically, since the port size of the water outlet is small, the water flow inside the nozzle 21 will be squeezed to a certain extent when passing through the outlet, thereby increasing the speed of the water flow spraying and ensuring the spraying effect. At the same time, the port size of the water outlet is small, which helps to form a thinner water line when the water flow is sprayed out, thereby achieving uniform wetting of the humidification core 1 with less water, ensuring humidification efficiency and reducing costs.

[0048] See also Figure 3 In this embodiment, a protrusion 212 is provided on the side surface of the water outlet end of the water spray trough 211, and the protrusion 212 protrudes from the side surface of the trough on this side toward the inside of the water spray trough 211, so that the size of the water outlet port of the water spray trough 211 is reduced, thereby ensuring the water outlet speed and the formation of the water line.

[0049] Optionally, a cross-sectional area of ​​the first water supply channel 4 gradually decreases from an end away from the nozzle 21 to an end close to the nozzle 21 .

[0050] like Figure 1 As shown, the shape of the support column 3 is set to be conical, with a larger size at the bottom and a smaller size at the top. The shape of the first water supply channel 4 is adapted to the support column 3. The cross-sectional area of ​​the first water supply channel 4 gradually decreases from the water inlet end at the bottom to the water outlet end at the top, which is beneficial to increase the speed and pressure of water outlet, so that the water flow can smoothly drive the nozzle 21 to rotate after entering the nozzle 21, prevent the nozzle 21 from getting stuck during the rotation process, and further ensure the effect of rotary spraying.

[0051] Optionally, the spray assembly 2 also includes an upper cover 22 and a lower cover 23, the upper cover 22 and the lower cover 23 are fixedly connected by a bracket 24, and there is a gap between the upper cover 22 and the lower cover 23; the spray head 21 is rotatably installed between the upper cover 22 and the lower cover 23, and the lower cover 23 is connected to the top of the support column 3.

[0052] For details, see Figure 2The spray assembly 2 also includes an upper cover 22 and a lower cover 23. The cover parts of the upper cover 22 and the lower cover 23 are both arc-shaped surfaces. The upper cover 22 and the lower cover 23 are arranged in a concave manner and supported and fixed by a bracket 24. Specifically, in this embodiment, the lower end of the bracket 24 is connected and fixed to the lower cover 23 by a screw 7, and the upper end of the bracket 24 is provided with a snap-fit ​​structure, which is connected and fixed to the upper cover 22 by a snap-fit ​​manner. Under the support of the bracket 24, an accommodating space is formed between the upper cover 22 and the lower cover 23, and the nozzle 21 is rotatably installed in the accommodating space. By setting the upper cover 22 and the lower cover 23, the nozzle 21 can be protected from being exposed, preventing the user from damaging the nozzle 21 when replacing the humidification core 1, and also making the appearance of the product more concise and beautiful.

[0053] It is understandable that the upper cover 22 and the lower cover 23 are not in a closed state, and a certain gap needs to be left between the lower edge of the upper cover 22 and the upper edge of the lower cover 23 to ensure that the water flow sprayed by the nozzle 21 can pass through the gap and be sprayed onto the top of the humidification core 1. In practical applications, the size of the gap can be flexibly set according to the height of the water outlet port of the nozzle 21 and the size of the water pressure.

[0054] Optionally, a positioning shaft 213 is provided at one end of the nozzle 21 away from the lower cover 23 ; a positioning hole 241 is provided on the bracket 24 at a position corresponding to the positioning shaft 213 , and the positioning shaft 213 is rotatably connected in the positioning hole 241 .

[0055] Specifically, Figure 2 As shown, a positioning shaft 213 is provided at the upper end of the nozzle 21, and the positioning shaft 213 is located at the axis of the nozzle 21, and is coaxially arranged with the lower cover 23 and the support column 3. A positioning hole 241 is provided at the upper end of the bracket 24 at a position corresponding to the positioning shaft 213, and the size of the positioning hole 241 is slightly larger than the size of the positioning shaft 213. During assembly, the upper and lower ends of the bracket 24 are respectively fixed to the upper cover 22 and the lower cover 23, and the lower end of the nozzle 21 is rotatably connected to the lower cover 23, and the positioning shaft 213 at the upper end of the nozzle 21 is rotatably connected to the positioning hole 241 of the bracket 24. By providing the positioning shaft 213 and the positioning hole 241, the installation stability of the nozzle 21 can be improved, and the nozzle 21 can be prevented from falling off and flying out of the lower cover 23 due to the impact of the water flow, thereby ensuring safety and reliability during use.

[0056] Optionally, the lower cover 23 includes an integrally formed lower cover body 231, a first connecting part 232 and a second connecting part 233; the first connecting part 232 and the second connecting part 233 are both arranged at the center of the lower cover body 231, the first connecting part 232 is connected to the support column 3, and the second connecting part 233 is rotatably connected to the nozzle 21; a hollow second water supply channel 5 is formed inside the first connecting part 232 and the second connecting part 233, and the water inlet end of the second water supply channel 5 is connected to the water outlet end of the first water supply channel 4, and the water outlet end of the second water supply channel 5 is connected to the water inlet end of the water spraying channel 6.

[0057] Specifically, the lower cover 23 includes a lower cover body 231, a first connection portion 232 and a second connection portion 233, both of which are located at the axis of the lower cover body 231, wherein the first connection portion 232 is used to connect with the top end of the support column 3, and the second connection portion 233 is used to connect with the bottom end of the nozzle 21. The first connection portion 232 and the second connection portion 233 are hollow inside to form a second water supply channel 5, which is connected between the first water supply channel 4 and the water spray channel 6. The cross-sectional area of ​​the second water supply channel 5 gradually decreases from the water inlet end to the water outlet end, realizing the transition between the first water supply channel 4 and the water spray channel 6, and also achieving the effect of pressurization, increasing the pressure when the water flow enters the nozzle 21, further ensuring the smooth rotation of the nozzle 21, and reducing the requirements for the water pressure of the water pump.

[0058] Optionally, a plurality of water leakage holes are provided on the lower cover body 231 .

[0059] Specifically, since the lower cover 23 is arranged at the bottom of the nozzle 21, during the spraying and humidification process, the water sprayed from the nozzle 21 may splash onto the lower cover body 231 and accumulate in the lower cover body 231. By providing a plurality of leakage holes on the lower cover body 231, the water falling into the lower cover body 231 can be discharged in time to prevent scale from being generated in the lower cover body 231 due to long-term accumulation of water, thereby preventing the connection between the nozzle 21 and the first connecting part 232 from being blocked, thereby affecting the smoothness of the rotation of the nozzle 21 and the spraying of water.

[0060] Optionally, the first connection portion 232 is detachably connected to the support column 3 .

[0061] Specifically, a convex buckle is provided at the top of the support column 3, and a snap-in hole is provided at a corresponding position on the first connection portion 232. The convex buckle and the snap-in hole can realize a detachable connection between the support column 3 and the first connection portion 232. When the humidifier is used for a period of time and scale or dirt appears in the spray assembly 2, the user can easily remove the spray assembly 2 from the top of the support column 3 for easy cleaning and replacement.

[0062] In other embodiments, the first connection portion 232 and the support column 3 may be detachably connected by threaded engagement or by using bolt fasteners.

[0063] Optionally, a sealing ring 8 is also provided at the connection between the first connecting portion 232 of the lower cover 23 and the support column 3 to achieve a sealed connection between the spray assembly 2 and the support column 3, thereby preventing water from leaking from the joint between the lower cover 23 and the support column 3 during transportation, causing water loss and affecting the humidification effect of the humidification core 1.

[0064] Optionally, the rotary spray humidification structure further includes a humidification core 1 frame for mounting the humidification core 1 , the humidification core 1 frame includes a base 9 , and the support column 3 is vertically arranged at the center of the base 9 .

[0065] Specifically, the humidifying core 1 frame is used to install and fix the humidifying core 1. In this embodiment, the humidifying core 1 is a hollow cylindrical structure. The humidifying core 1 frame includes a frame body, a bottom bracket 9 arranged at the bottom of the frame body, and a top cover arranged at the top of the frame body. The cylindrical humidifying core 1 is sleeved on the periphery of the frame body and fixed between the top cover and the bottom bracket 9. The support column 3 is vertically arranged at the center of the bottom bracket 9 and coaxially arranged inside the humidifying core 1. The top end of the support column 3 is used to install the nozzle 21. The bottom end of the support column 3 is connected and fixed to the bottom bracket 9, which improves the stability of the installation of the nozzle 21, and at the same time maximizes the use of the internal space of the humidifying core 1 and optimizes the size of the humidifying structure.

[0066] The top cover covers the upper end surface of the humidifying core 1 and is provided with a plurality of evenly distributed fine holes. When the water flow sprayed from the nozzle 21 falls on the top cover, the water flow can enter the upper end of the humidifying core 1 through these fine holes, thereby quickly and evenly moistening the humidifying core 1.

[0067] The rotary spray humidification structure provided by the embodiment of the present application, when the water pump is started, the water in the water tank will enter the first water supply channel 4 in the support column 3 from bottom to top through the pipeline, and then rise to enter the second water supply channel 5 in the lower cover 23 of the spray assembly 2, and then enter the water spray channel 6 in the nozzle 21. Since the water spray channel 6 is an eccentric structure, under the impact of water pressure, the nozzle 21 can rotate along its axis, and the sprayed water flow changes direction continuously with the rotation of the nozzle 21, and finally sprays out in a 360-degree ring, falls on the top of the humidification core 1, and moistens the humidification core 1 evenly and quickly; when the purified air passes through the moistened humidification core 1 with the blowing of the wind wheel, it will bring water vapor into the environment of the indoor space, and finally play a role in increasing the humidity of the indoor space. The rotary spray humidification structure provided by the embodiment of the present application has a simple structure, low component cost, small amount of water required for humidification, low water pressure requirement for the water pump, good spray uniformity, high humidification efficiency, and helps to improve the humidification performance and user experience of the machine.
