Description

Technical Field

[0001] This application relates to the technical field of humidifiers, and more specifically, to a small humidifier with an anti-drip and anti-condensation fog outlet. Background Art

[0002] With the improvement of people's living standards and the pursuit of quality of life, small humidifiers are increasingly widely used in daily life. Especially in relatively small spaces such as office desktops, they can effectively improve the local air humidity and create a more comfortable working and living environment for people. In dry seasons or environments, low air humidity can cause problems such as dry skin and respiratory discomfort. Small humidifiers increase the air humidity by converting water into fine water mist and releasing it into the air, thereby alleviating these discomfort symptoms. In recent years, the continuous development of electronic technology, material science, and manufacturing processes has greatly improved the performance, appearance, and functions of small humidifiers.

[0003] However, there are still some problems in the use of existing small desktop humidifiers. When the humidifier is working, the water mist diffuses in the air through the fog outlet. During the diffusion process, some water mist will condense into water droplets at the fog outlet. If too many water droplets accumulate, there will be a water leakage phenomenon, which will not only wet the desktop but also damage documents, electronic devices, etc. placed around. At the same time, excessive fog condensation near the fog outlet will affect the fog outlet effect of the humidifier, making the fog unable to spread evenly into the air and reducing the humidification efficiency. Summary of the Utility Model

[0004] To solve the above problems, this application provides a small humidifier with an anti-drip and anti-condensation fog outlet.

[0005] The small humidifier with an anti-drip and anti-condensation fog outlet provided by this application adopts the following technical solutions:

[0006] A small humidifier with an anti-drip and anti-condensation fog outlet includes a housing. An air outlet channel is provided inside the housing, and a fog discharge cylinder is provided inside the air outlet channel. A partition plate is connected inside the fog discharge cylinder, and the partition plate divides the fog discharge cylinder into two fog discharge channels. The inner diameters of the two fog discharge channels increase from top to bottom. The top of the fog discharge channel is communicatively provided with a fog outlet, and the fog outlet is located on one side of the housing.

[0007] Through the above technical solutions, the fog discharge channels gradually reduce the flow rate of the water mist in the fog discharge channels and increase the pressure, reducing the possibility of the water mist condensing due to too fast a flow rate impact at the fog outlet, so that it flows more stably towards the fog outlet. And the relatively large bottom space may help the preliminary mixing and buffering of the water mist, making the state of the water mist more uniform and stable, and further reducing the condensation risk.

[0008] Furthermore, water guide rings are provided inside both of the two fog exhaust channels, and the cross-sections of the two water guide rings are both triangular.

[0009] Through the above technical solution, the water at the bottom of the water guide ring can be recycled back to the water storage cavity through the return pipe and the connecting pipe, realizing the recycling of water resources.

[0010] Furthermore, an atomizing device is provided inside the housing, and a water storage cavity is provided inside the housing.

[0011] Furthermore, the water storage cavity is located above the atomizing device, an atomizing pipe is communicatively provided between the atomizing device and the water storage cavity, and a water adding pipe is communicatively provided at the top of the water storage cavity, and the water adding pipe extends through to the outside of the housing.

[0012] Through the above technical solution, the water adding pipe can add water to the water storage cavity from outside the housing to ensure that the humidifier has enough water source for atomizing work.

[0013] Furthermore, an air outlet pipe is communicatively provided at the bottom end of the atomizing device, and one end of the air outlet pipe far away from the atomizing device is communicatively connected with the air outlet channel.

[0014] Furthermore, a blower is provided at the bottom end of the housing, and the air outlet of the blower is communicatively connected with the air outlet channel.

[0015] Furthermore, heat insulation cotton is provided on the outer wall of the air outlet channel, and a heating ring is provided on the outer wall of the air outlet.

[0016] Through the above technical solution, the heat insulation cotton can reduce the heat dissipation in the air outlet channel. For some situations where the atomizing effect may be affected by temperature changes or water mist may condense again, the heat insulation cotton plays a certain heat preservation role, keeping the temperature in the air outlet channel relatively stable, which helps the water mist maintain a good atomized state and flow smoothly.

[0017] Furthermore, one end of each of the two water guide rings is communicatively provided with a return pipe and a connecting pipe respectively, the return pipe is communicatively connected with the connecting pipe, and one end of the return pipe is communicatively connected with the water storage cavity.

[0018] Through the above technical solution, the heating ring provided on the outer wall of the air outlet will generate heat during operation. When the water mist is sprayed out of the air outlet into the air, the heat of the heating ring can increase the temperature near the air outlet, preventing the water mist from quickly condensing into water droplets at the air outlet due to the relatively cold external environment, thereby achieving the effect of preventing dripping and condensing fog.

[0019] In summary, the present application includes at least the following beneficial technical effects:

[0020] (1) By setting up the mist exhaust channel, the present utility model enables the flow rate of the water mist in the mist exhaust channel to gradually decrease and the pressure to gradually increase, reducing the possibility of the water mist condensing due to the too-fast impact at the mist outlet, thus flowing more stably towards the mist outlet. And the relatively large bottom space may contribute to the preliminary mixing and buffering of the water mist, making the state of the water mist more uniform and stable, and further reducing the condensation risk.

[0021] (2) The heat-insulating cotton provided on the outer wall of the air outlet channel in the present utility model can reduce the heat dissipation in the air outlet channel. For some situations where the atomization effect may be affected by temperature changes or water mist may condense again, the heat-insulating cotton plays a certain heat-preserving role, keeping the temperature in the air outlet channel relatively stable, which helps the water mist maintain a good atomized state and flow smoothly.

[0022] (3) The heating ring provided on the outer wall of the mist outlet in the present utility model generates heat during operation. When the water mist is sprayed out of the mist outlet into the air, the heat of the heating ring can increase the temperature near the mist outlet, preventing the water mist from quickly condensing into water droplets due to encountering a relatively cold external environment, thus achieving the effect of anti-drip and anti-condensation of the mist.

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0030] Reference Figures 1-5 A small humidifier with anti-drip condensation at the mist outlet comprises a shell 1, an air outlet channel 8 is arranged inside the shell 1, a mist exhaust tube 17 is arranged inside the air outlet channel 8, a partition plate 9 is connected to the inside of the mist exhaust tube 17, the partition plate 9 divides the mist exhaust tube 17 into two mist exhaust channels 10, the inner diameters of the two mist exhaust channels 10 increase from top to bottom, a mist outlet 2 is arranged at the top of the mist exhaust channel 10, and the mist outlet 2 is located on one side of the shell 1.

[0031] When the humidifier is working, the atomizing device 3 sucks and atomizes the water in the water storage chamber 5 through the atomizing tube 4, and the atomized water mist enters the air outlet channel 8 through the mist outlet pipe 7. The fan 11 is started, and the generated mist is sprayed out from the air outlet channel 8. At this time, since the mist exhaust tube 17 is located in the air outlet channel 8 and is divided into two mist exhaust channels 10 by the partition plate 9, the water mist will enter the two mist exhaust channels 10 with increasing inner diameters from top to bottom. Through the setting of the mist exhaust channel 10, the flow rate of the water mist in the mist exhaust channel 10 is gradually reduced, and the pressure is gradually increased, which reduces the possibility of the water mist condensing at the mist outlet 2 due to the impact of excessive flow rate, so that it flows to the mist outlet 2 more stably, and the larger bottom space may help the initial mixing and buffering of the water mist, making the water mist state more uniform and stable, further reducing the risk of condensation.

[0032] Finally, the water mist is discharged from the mist outlet 2 at the top of the mist exhaust channel 10 to the outside of the housing 1, thereby humidifying the surrounding air.

[0033] Reference Figures 3-4 A water guide ring 12 is provided inside the two mist exhaust channels 10, and the cross-sections of the two water guide rings 12 are both triangular. An atomizing device 3 is provided inside the shell 1, and a water storage chamber 5 is provided inside the shell 1. The water storage chamber 5 is located above the atomizing device 3. An atomizing pipe 4 is provided between the atomizing device 3 and the water storage chamber 5, and a water adding pipe 6 is provided on the top of the water storage chamber 5, and the water adding pipe 6 extends through to the outside of the shell 1.

[0034] The water in the water storage cavity 5 flows through the atomization tube 4 to the atomization device 3. The atomization device 3 uses a specific principle (such as ultrasonic vibration) to convert water into fine water mist. When the water mist moves in the mist discharge channel 10, part of the water mist will contact the inner wall of the mist discharge channel 10 and adhere to it. After a large amount of water mist adheres to the top of the mist discharge channel 10, water droplets will form and flow back. Since the cross-section of the water guide ring 12 is triangular, the water droplets will converge along the inclined surface of the triangle to the bottom of the water guide ring 12. The two water guide rings 12 are connected to the connecting pipe 15 through the return pipe 13, and one end of the return pipe 13 is connected to the water storage cavity 5. Therefore, the water converging at the bottom of the water guide ring 12 can flow back into the water storage cavity 5 through the return pipe 13 and the connecting pipe 15, realizing the recycling of water resources.

[0035] Through the water adding pipe 6 connected to the top of the water storage cavity 5, water can be added to the water storage cavity 5 from outside the housing 1 to ensure that the humidifier has enough water source for atomization work.

[0036] Refer to Figures 2-3 , at the bottom end of the atomization device 3, a mist outlet pipe 7 is connected and provided. One end of the mist outlet pipe 7 far from the atomization device 3 is connected to the air outlet channel 8. At the bottom end of the housing 1, a fan 11 is provided. The air outlet of the fan 11 is connected to the air outlet channel 8. The outer wall of the air outlet channel 8 is provided with a heat insulation cotton 14, and the outer wall of the mist outlet 2 is provided with a heating ring 16.

[0037] The heat insulation cotton 14 provided on the outer wall of the air outlet channel 8 can reduce the heat loss in the air outlet channel 8. For some situations where the atomization effect may be affected by temperature changes or water mist may condense again, the heat insulation cotton 14 plays a certain heat preservation role, keeping the temperature in the air outlet channel 8 relatively stable, which helps the water mist to maintain a good atomized state and flow smoothly.

[0038] The heating ring 16 provided on the outer wall of the mist outlet 2 will generate heat when working. When the water mist is sprayed out of the mist outlet 2 into the air, the heat of the heating ring 16 can increase the temperature near the mist outlet 2, preventing the water mist from quickly condensing into water droplets at the mist outlet 2 due to the relatively cold external environment, thus achieving the effect of preventing dripping and condensing mist.

[0039] The heating ring 16 is made by winding a heating resistance wire on a ceramic substrate. After being powered on, the resistance wire generates heat, and the heat is conducted out through the ceramic substrate.

[0040] Refer to Figures 3-4 , at one end of the two water guide rings 12, a return pipe 13 and a connecting pipe 15 are respectively connected and provided. The return pipe 13 is connected to the connecting pipe 15, and one end of the return pipe 13 is connected to the water storage cavity 5.

[0041] The bottom of the water guide ring 12 is connected to the return water pipe 13 through a connecting pipe 15, and the return water pipe 13 is also connected to the water storage cavity 5. In this way, the water converging at the bottom of the water guide ring 12 can flow back into the water storage cavity 5 through the connecting pipe 15 and the return water pipe 13, realizing the recycling of water.

[0042] Working principle: When the small humidifier is turned on, the water in the water storage cavity 5 above the interior of the housing 1 flows through the atomizing pipe 4 to the atomizing device 3. The atomizing device 3 uses principles such as ultrasonic vibration to convert water into fine water mist. The atomized water mist enters the air outlet passage 8 inside the housing 1 through the mist outlet pipe 7. At this time, the fan 11 at the bottom end of the housing 1 starts, and the generated air flow enters the air outlet passage 8, driving the water mist to flow in the air outlet passage 8.

[0043] Since a mist discharge cylinder 17 is provided inside the air outlet passage 8, and the mist discharge cylinder 17 is separated by a partition plate 9 into two mist discharge passages 10 with an inner diameter increasing from top to bottom, the water mist will enter these two passages respectively. In the mist discharge passage 10, the flow rate of the water mist gradually decreases and the pressure gradually increases. At the same time, the relatively large bottom space helps the preliminary mixing and buffering of the water mist, making the state of the water mist more uniform and stable, and reducing the possibility of condensation due to too fast impact at the mist outlet 2.

[0044] When the water mist moves in the mist discharge passage 10, part of the water mist will contact the inner wall of the mist discharge passage 10 and adhere. A large amount of water droplets are formed after adhering to the top of the passage and flow back. Because the cross-section of the water guide ring 12 provided inside the mist discharge passage 10 is triangular, the water droplets will converge to the bottom of the water guide ring 12 along its inclined plane. The two water guide rings 12 are connected to the return water pipe 13 through the connecting pipe 15, and the return water pipe 13 is also connected to the water storage cavity 5, so that the water converging at the bottom of the water guide ring 12 can flow back into the water storage cavity 5, realizing the recycling of water resources.

[0045] During the whole process, the heat insulation cotton 14 on the outer wall of the air outlet passage 8 plays a role in reducing heat dissipation, keeping the temperature inside the air outlet passage 8 relatively stable, and helping the water mist to maintain a good atomized state and flow smoothly. The heating ring 16 on the outer wall of the mist outlet 2 is made by winding a heating resistance wire on a ceramic substrate and generates heat during operation. When the water mist is sprayed out of the mist outlet 2 into the air, the heat of the heating ring 16 can increase the temperature near the mist outlet 2, preventing the water mist from quickly condensing into water droplets due to encountering a colder external environment, and finally realizing the effect of humidifying the surrounding air and preventing dripping and fogging.

[0046] The above are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
