Technical Field

[0001] This application relates to the field of humidification equipment technology, and in particular to a mist-free humidifier. Background Technology

[0002] Mist-free humidifiers achieve humidification through ultrasonic or cold evaporation technology, which can effectively improve the air pollution problem caused by water mist produced by traditional humidifiers. Currently, mist-free humidifiers are widely used in various environments such as homes and offices.

[0003] However, during the use of a mistless humidifier, the water in the tank is usually not completely drained, and the residual water stains can easily breed bacteria and mold, leading to odors and hygiene hazards. Utility Model Content

[0004] Therefore, it is necessary to provide a mist-free humidifier to address the problem that current mist-free humidifiers easily leave water stains in the water tank, leading to odors and hygiene hazards.

[0005] This application provides a mist-free humidifier, including a humidifying body, a water tank, a first fan, and a heating element. The humidifying body has an air outlet. The water tank is connected to the humidifying body and is located on the side of the humidifying body away from the air outlet. The first fan is disposed inside the water tank, and the heating element is disposed on the inner wall of the water tank to generate heat and dry the residual water in the water tank.

[0006] Therefore, through the above structure, the heating element can evenly transfer heat to each residual water area through the inner wall of the water tank, better maintaining the dryness inside the water tank and reducing the probability of risks such as odors and hygiene hazards. Furthermore, by setting up a first fan, the heat generated by the heating element can be converted into hot airflow, promoting the circulation of hot air inside the water tank, thereby further accelerating the evaporation of water.

[0007] According to one or more embodiments, the water tank has a bottom wall and side walls surrounding the outer periphery of the bottom wall, the bottom wall being disposed opposite to the air outlet, and the first fan being disposed on the bottom wall.

[0008] Therefore, the above structure allows the heat generated by the heating element to be blown upwards, making the heat distribution in the water tank more uniform.

[0009] According to one or more embodiments, the heating components include at least two, and each heating component is disposed on two opposite sidewalls.

[0010] The above structure can generate more heat and distribute it quickly and evenly in the water tank, thus achieving rapid drying of the water tank.

[0011] According to one or more embodiments, an installation port is provided on the side wall, the heating component includes a PTC heating element and a bracket, the PTC heating element is fixed on the bracket, and the bracket is installed in the installation port.

[0012] Thus, heat is successfully generated inside the water tank by the PTC heating element, and the PTC heating element is easily fixed to the side wall of the water tank by the bracket. The structure is simple and easy to operate.

[0013] According to one or more embodiments, the heating component further includes a sealing ring surrounding the outer periphery of the mounting port and sealingly disposed between the PTC heating element and the side wall.

[0014] Therefore, by using the above structure to seal the gap between the PTC heating element and the side wall, the closed environment inside the water tank can be better maintained, reducing the probability of water leakage.

[0015] According to one or more embodiments, a groove is provided on the side wall, the groove is disposed around the outer periphery of the mounting opening, and the sealing ring has a protrusion that engages with the groove.

[0016] Therefore, the above structure allows the sealing ring to be more stably positioned between the PTC heating element and the side wall, and effectively improves the sealing performance.

[0017] According to one or more embodiments, the sealing ring is constructed as a high-temperature silicone sealing ring. Therefore, with the above structure, the impact of the heat generated by the PTC heating element on the sealing performance of the sealing ring can be reduced, making the structure and sealing performance of the sealing ring more stable.

[0018] According to one or more embodiments, the humidifying body further has an air inlet and includes a second fan, a liquid distributor, and a wet curtain arranged sequentially between the air outlet and the air inlet. The second fan is arranged facing the air outlet, and the wet curtain is arranged at the air inlet. The liquid distributor is connected to the water tank and is used to distribute the water in the water tank onto the wet curtain.

[0019] Therefore, the above structure can be used to humidify dry air and achieve a humidification effect.

[0020] According to one or more embodiments, the mist-free humidifier further includes a water pump connected between the water tank and the distributor for drawing water from the water tank to the distributor.

[0021] Therefore, by setting up a water pump, the water in the water tank can be smoothly drawn into the distributor above, and then the water flow is evenly distributed to the wet curtain below, thus achieving the humidification effect.

[0022] According to one or more embodiments, the mist-free humidifier further includes a temperature sensor disposed inside the water tank, the temperature sensor being used to detect the drying temperature inside the water tank.

[0023] Therefore, by setting a temperature sensor, the drying process can be better controlled, making the drying process smoother and safer.

[0024] The aforementioned mist-free humidifier has a heating element and a first fan installed inside the water tank. The heating element generates heat and distributes it evenly to all residual water areas through the inner wall of the water tank. At the same time, the first fan accelerates airflow circulation, further accelerating water evaporation and better maintaining the dryness inside the water tank, reducing the probability of odors and hygiene hazards.

[0037] See Figure 1 One embodiment of this application provides a mist-free humidifier 100, including a humidifying body 10, a water tank 20, and a heating element 30. The humidifying body 10 has an air outlet 11, and the water tank 20 is connected to the humidifying body 10 and located on the side of the humidifying body 10 away from the air outlet 11. The heating element 30 is disposed on the inner wall of the water tank 20 and is used to generate heat and dry the residual water in the water tank 20.

[0038] Specifically, the humidifying body 10 refers to a structure capable of humidifying gas and then providing the humidified gas to the external environment to achieve a humidification effect. The water tank 20 is hollow inside and can be used to store water so as to provide water flow to the humidifying body 10, thereby achieving humidification.

[0039] The water tank 20 is connected to the humidification body 10, so that the water in the water tank 20 can be smoothly transferred to the humidification body 10, and then the humidification body 10 provides humidified gas.

[0040] The humidifier body 10 has an air outlet 11. When dry external gas enters the humidifier body 10, it is humidified under the action of the humidifier body 10, and then the humidified gas is blown out from the air outlet 11, thereby achieving the humidification effect.

[0041] The heating element 30 is located on the inner wall of the water tank 20. The heating element 30 can generate heat in a controlled manner. After the mist-free humidifier 100 completes the humidification task, the heat generated by the heating element 30 is evenly transferred through the inner wall of the water tank 20 to various residual water areas of the water tank 20 to dry the residual water. In this way, the inside of the water tank 20 can be kept drier.

[0042] Thus, through the above structure, the heating element 30 can evenly transfer heat to each residual water area through the inner wall of the water tank 20, better maintain the dryness inside the water tank 20, and reduce the probability of generating odors and hygiene hazards.

[0043] In some embodiments, the mist-free humidifier 100 further includes a first fan 40 disposed within the water tank 20.

[0044] Specifically, a first fan 40 is installed inside the water tank 20. When the heating component 30 generates heat, the heat forms a hot airflow under the action of the first fan 40, which promotes the circulation of hot air inside the water tank 20 and can further accelerate the evaporation of water.

[0045] Furthermore, the mist-free humidifier 100 may also include a drive motor, which is connected to the first fan 40 in a drive connection, so that the drive motor can smoothly drive the first fan 40 to rotate.

[0046] A sealing structure can be provided between the first fan 40 and the inner wall of the water tank 20, for example, by using high-temperature silicone or other sealing rings to achieve a seal between the first fan 40 and the inner wall of the water tank 20.

[0047] Therefore, by setting the first fan 40, the heat generated by the heating component 30 can be converted into hot airflow, promoting the circulation of hot air in the water tank 20, thereby further accelerating the evaporation of water.

[0048] In some embodiments, the water tank 20 has a bottom wall 21 and a side wall 22 surrounding the outer periphery of the bottom wall 21. The bottom wall 21 is disposed opposite to the air outlet 11, and the first fan 40 is disposed on the bottom wall 21.

[0049] Specifically, the bottom wall 21 of the water tank 20 is also constructed as the bottom wall 21 of the mist-free humidifier 100. The bottom wall 21 is arranged opposite to the air outlet 11, that is, the air outlet 11 is located at the top of the mist-free humidifier 100.

[0050] The first fan 40 is set on the bottom wall 21. When the heating component 30 generates heat, the first fan 40 blows the hot air upwards, so that the heat is distributed more evenly in the water tank 20.

[0051] Therefore, through the above structure, the heat generated by the heating element 30 can be blown from bottom to top, making the heat distribution in the water tank 20 more uniform.

[0052] In some embodiments, the heating element 30 includes at least two, and each heating element 30 is disposed on two opposite sidewalls 22.

[0053] Specifically, two heating elements 30 can be configured, and the two heating elements 30 are respectively disposed on two opposite side walls 22. In this way, the heating elements 30 can generate more heat, and the first fan 40 on the bottom wall 21 blows the heat from bottom to top, so that the heat is quickly and evenly distributed in the water tank 20, thereby achieving rapid drying of the water tank 20.

[0054] Understandably, in some other embodiments, the number of heating components 30 may also be set to three or four or even more, which can be adjusted according to actual usage requirements, and will not be elaborated here.

[0055] The above structure can generate more heat and distribute the heat quickly and evenly in the water tank 20, thereby achieving rapid drying of the water tank 20.

[0056] like Figure 2 and Figure 3 As shown, in some embodiments, an installation port 23 is provided on the side wall 22, and the heating component 30 includes a PTC heating element 31 and a bracket 32. The PTC heating element 31 is fixed on the bracket 32, and the bracket 32 ​​is installed in the installation port 23.

[0057] Specifically, the PTC heating element 31 can be, but is not limited to, a PTC ceramic heating element. The PTC ceramic heating element has self-temperature control characteristics, which can effectively reduce the risk of overheating and can fit tightly against the inner wall of the water tank 20.

[0058] The PTC ceramic heating element is fixed on the bracket 32, and then the bracket 32 ​​is installed into the mounting port 23. In this way, the bracket 32 ​​can seal the mounting port 23 while installing the PTC ceramic heating element.

[0059] Furthermore, the bracket 32 ​​can be fixed to the water tank 20 with screws for easy disassembly and replacement.

[0060] Thus, heat is successfully generated inside the water tank 20 by the PTC heating element 31, and the PTC heating element 31 is successfully fixed to the side wall 22 of the water tank 20 by the bracket 32. The structure is simple and easy to operate.

[0061] In some embodiments, the heating element 30 further includes a sealing ring 33, which surrounds the outer periphery of the mounting port 23 and is sealed between the PTC heating element 31 and the side wall 22.

[0062] Specifically, the sealing ring 33 surrounds the outer periphery of the mounting port 23 and seals the gap between the PTC heating element 31 and the side wall 22.

[0063] Therefore, by using the above structure to seal the gap between the PTC heating element 31 and the side wall 22, the closed environment inside the water tank 20 can be better maintained, reducing the probability of water leakage in the water tank 20.

[0064] like Figure 4 and Figure 5 As shown, in some embodiments, a groove 24 is provided on the side wall 22, the groove 24 is arranged around the outer periphery of the mounting port 23, and the sealing ring 33 has a protrusion 34 that engages with the groove 24.

[0065] Specifically, a groove 24 is formed on the side wall 22, and the groove 24 surrounds the outer periphery of the mounting port 23. When the sealing ring 33 is placed between the PTC heating element 31 and the side wall 22, the protrusion 34 on the sealing ring 33 can be inserted into the groove 24 on the side wall 22, so that the sealing ring 33 is more stably placed between the PTC heating element 31 and the side wall 22, and the sealing performance can be effectively improved.

[0066] Thus, the above structure allows the sealing ring 33 to be more stably positioned between the PTC heating element 31 and the side wall 22, and effectively improves the sealing performance.

[0067] In some embodiments, the sealing ring 33 is configured as a high-temperature silicone sealing ring.

[0068] Specifically, when the PTC heating element 31 generates heat, the high-temperature silicone sealing ring has a more stable sealing performance.

[0069] Understandably, sealing ring 33 can also be made of other high-temperature resistant sealing materials to achieve a high-temperature resistant sealing effect, which will not be elaborated here.

[0070] Therefore, the above structure can reduce the impact of the heat generated by the PTC heating element 31 on the sealing performance of the sealing ring 33, making the structure and sealing performance of the sealing ring 33 more stable.

[0071] Please refer to it again. Figure 1 In some embodiments, the humidifier body 10 further includes an air inlet 12 and a second fan 13, a water distributor 14, and an evaporative cooling pad 15, which are sequentially arranged between the air outlet 11 and the air inlet 12. The second fan 13 is positioned towards the air outlet 11, and the evaporative cooling pad 15 is positioned at the air inlet 12. The water distributor 14 is connected to the water tank 20 and is used to distribute the water in the water tank 20 onto the evaporative cooling pad 15.

[0072] Specifically, the evaporative cooling pad 15 is positioned above the water tank 20, and a liquid distributor 14 is positioned above the evaporative cooling pad 15. A second fan 13 is positioned above the liquid distributor 14, with the second fan 13 facing the air outlet 11. The air inlet 12 is positioned on the side wall 22, and the evaporative cooling pad 15 is positioned at the air inlet 12.

[0073] Furthermore, the distributor 14 is connected to the water tank 20, so that water in the water tank 20 can be transferred to the distributor 14, and then the distributor 14 distributes the water evenly onto the wet curtain 15 below it, so that the wet curtain 15 is fully moistened. When the second fan 13 is started, the air from the outside environment is drawn into the mist-free humidifier 100 through the air inlet 12, passes through the moistened wet curtain 15, and is then blown out from the air outlet 11 under the action of the second fan 13, thus achieving the humidification effect.

[0074] Therefore, the above structure can be used to humidify dry air and achieve a humidification effect.

[0075] In some embodiments, the mist-free humidifier 100 further includes a water pump 50 connected between the water tank 20 and the distributor 14, for drawing water from the water tank 20 to the distributor 14.

[0076] Specifically, the water pump 50 can be installed in the water tank 20 and connected to the distributor 14 via a pipe. The water pump 50 can draw water from the water tank 20 into the distributor 14 above, and then the distributor 14 distributes the water flow evenly to the wet curtain 15 below.

[0077] Understandably, the wet curtain 15 is an evaporative filter or a humidifying filter element.

[0078] Therefore, by setting up a water pump 50, the water in the water tank 20 can be smoothly drawn into the upper distributor 14, and then the water is evenly distributed to the wet curtain 15 below through the distributor 14, thus achieving the humidification effect.

[0079] In some embodiments, the mist-free humidifier 100 further includes a temperature sensor (not shown) disposed inside the water tank 20, which is used to detect the drying temperature inside the water tank 20.

[0080] Specifically, during the drying process, the actual temperature inside the water tank 20 can be detected by a temperature sensor. If the temperature is too high or too low, it indicates that there is an abnormality in the drying process, such as insufficient heat generated due to damage to the PTC heating element 31, or overheating of the PTC heating element 31. The drying process can be adjusted in time to make the drying process smoother and safer.

[0081] Therefore, by setting a temperature sensor, the drying process can be better controlled, making the drying process smoother and safer.

[0082] According to one or more embodiments, when the mist-free humidifier 100 performs the humidification task, the water in the water tank 20 is first drawn into the upper liquid distributor 14 by the water pump 50, and then the water is evenly distributed to the wet curtain 15 below by the liquid distributor 14, so that the wet curtain 15 is fully wetted.

[0083] Subsequently, the second fan 13 is activated, drawing in ambient air through the air inlet 12 and passing it over the surface of the wet curtain 15. As the air passes through the wet curtain 15, the moisture on the wet curtain 15 is naturally evaporated and enters the airflow, then is blown out through the air outlet 11, thereby increasing the humidity of the ambient air.

[0084] After the mist-free humidifier 100 completes its humidification task, water stains usually remain in the water tank 20. At this time, the PTC heating element 31 and the first fan 40 can be turned on. The PTC heating element 31 generates heat, and the first fan 40 blows hot air from bottom to top, promoting the circulation of hot air inside the water tank 20. In this way, the residual water inside the water tank 20 evaporates quickly, drying the water tank 20.

[0085] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0086] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
