Description

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, after using a mist-free humidifier, a large amount of moisture remains inside, especially on the humidifying components, which is difficult to evaporate naturally. As a result, the humidifying components remain damp for a long time, making them prone to the growth of bacteria, mold, and algae. This not only affects the hygiene of the mist-free humidifier but may also release harmful substances into the air, posing a safety hazard. Utility Model Content

[0004] Therefore, it is necessary to provide a mist-free humidifier to address the problem that water stains easily remain in the humidification components of current mist-free humidifiers, posing hygiene and safety hazards.

[0005] This application provides a mist-free humidifier, including a housing, a humidification component, a first fan, a second fan, and a heating element. The housing has an air inlet and an air outlet. The humidification component is disposed inside the housing and located between the air inlet and the air outlet. The first fan is disposed between the air outlet and the humidification component. The second fan is disposed between the air inlet and the humidification component. The heating element is disposed on the humidification component and is used to generate heat and dry the residual water on the humidification component.

[0006] Thus, through the synergistic action of the first fan, the second fan, and the heating element, a convection warm air circulation is formed on the upper and lower sides of the humidification component, allowing heat to pass through the humidification component more evenly, thereby ensuring that the humidification component is fully dried and effectively reducing the probability of bacterial growth.

[0007] According to one or more embodiments, the housing has a top wall, a bottom wall, and a side wall, the top wall and the bottom wall being disposed opposite each other, and the side wall being disposed between the top wall and the bottom wall; the air inlet is opened on the side wall and close to the bottom wall, and the air outlet is opened on the top wall; wherein, the second fan is fixed to the bottom wall and is disposed toward the humidification assembly.

[0008] Thus, through the above structure, the first fan and the second fan can smoothly form a convection warm air circulation on the upper and lower sides of the humidification component, achieving efficient drying of the humidification component.

[0009] According to one or more embodiments, the humidification assembly includes a wet curtain and a distributor for distributing water onto the wet curtain; the wet curtain is located below the distributor along the direction of gravity and is fixed to the side wall, and the wet curtain overlaps with at least a portion of the air inlet; wherein the heating element is disposed on the distributor.

[0010] Thus, through the above structure, on the one hand, the dry air from outside can pass through the wet curtain fully, thereby humidifying the air; on the other hand, while the heating element transfers heat to the wet curtain, a certain distance is maintained between the heating element and the wet curtain to avoid direct contact between the heating element and the wet curtain, which could cause damage.

[0011] According to one or more embodiments, the mist-free humidifier further includes a water tank and a water pump. The water tank is disposed inside the housing, and the water pump is connected between the water tank and the distributor for drawing water from the water tank to the distributor.

[0012] Therefore, by setting up a water tank and a water pump, the water storage function can be realized, and the water in the water tank can be smoothly drawn into the distributor. Then, the water is evenly distributed to the wet curtain below through the distributor, thus achieving the humidification effect.

[0013] According to one or more embodiments, the liquid distributor is disposed around the side wall, and the liquid distributor encloses an installation space, and the heating element is fixed within the installation space.

[0014] Thus, through the above structure, the heating element can cooperate with the first fan and the second fan to form a convective warm air circulation, so that the hot air can pass through the wet curtain evenly and achieve a good drying effect on the wet curtain.

[0015] According to one or more embodiments, the inner peripheral wall of the liquid distributor is provided with a plurality of support members extending toward the installation space, each of the support members being spaced apart along the circumference of the liquid distributor, the heating element being supported on each of the support members and being detachably connected to each of the support members.

[0016] The above structure enables a fixed connection between the heating element and the liquid distributor, allowing the heating element to be more stably installed inside the housing, thereby achieving the drying of the humidification component.

[0017] According to one or more embodiments, the heating element is constructed as a waterproof PTC heating element. Thus, by providing a waterproof PTC heating element, heat can be smoothly generated inside the housing, and in conjunction with the first and second fans, convective warm air circulation is formed on the upper and lower sides of the wet curtain, achieving a drying effect.

[0018] According to one or more embodiments, the mist-free humidifier further includes a temperature sensor disposed inside the housing, the temperature sensor being used to detect the drying temperature inside the housing.

[0019] Therefore, by setting a temperature sensor, the drying process can be better controlled, making the drying process smoother and safer.

[0020] According to one or more embodiments, the mist-free humidifier further includes a humidity sensor disposed inside the housing, the humidity sensor being used to detect the dryness of the humidification component.

[0021] With the above structure, the humidity sensor can detect the drying status of the wet curtain in real time during the drying process, so as to better adjust the drying process.

[0022] According to one or more embodiments, the mist-free humidifier further includes a timer disposed inside the housing, the timer being electrically connected to the first fan, the second fan and the heating element respectively, and used to start and stop the first fan, the second fan and the heating element at regular intervals.

[0023] In this way, the first fan, the second fan, and the heating element can be better controlled by the timer, thereby better controlling the drying time and adjusting the drying process.

[0024] The aforementioned mist-free humidifier has a humidification component positioned between the air inlet and outlet, humidifying the air entering the housing before blowing the humidified air out of the outlet, thus humidifying the external environment. Simultaneously, a first fan and a second fan are respectively installed between the air outlet and the humidification component, and between the air inlet and the humidification component. A heating element is also installed on the humidification component. After the mist-free humidifier is used, the heat generated by the heating element dries any remaining water on the humidification component. Furthermore, the first and second fans create convection warm air circulation on the upper and lower sides of the humidification component, ensuring that the heat generated by the heating element passes through the humidification component more evenly, allowing the humidification component to be thoroughly dried and effectively reducing the probability of bacterial growth.

[0035] See Figure 1 One embodiment of this application provides a mist-free humidifier 100, including a housing 10, a humidification component 20, a first fan 30, a second fan 40, and a heating element 50. The housing 10 has an air inlet 11 and an air outlet 12. The humidification component 20 is disposed inside the housing 10, between the air inlet 11 and the air outlet 12. The first fan 30 is disposed between the air outlet 12 and the humidification component 20, and the second fan 40 is disposed between the air inlet 11 and the humidification component 20. The heating element 50 is disposed on the humidification component 20 and is used to generate heat and dry residual water on the humidification component 20.

[0036] Specifically, the interior of the housing 10 is hollow, allowing it to accommodate components such as the humidification assembly 20, the first fan 30, the second fan 40, and the heating element 50. The housing 10 has an air inlet 11 and an air outlet 12, which are positioned opposite each other. This allows ambient air to enter the housing 10 through the air inlet 11, be humidified by the humidification assembly 20, and then blown out through the air outlet 12, thus achieving the humidification effect on the external environment.

[0037] Furthermore, the humidification component 20 refers to a structure capable of humidifying the gas entering the housing 10 and providing the humidified gas to the external environment to achieve a humidification effect. The humidification component 20 is positioned between the air inlet 11 and the air outlet 12. After external air enters the housing 10 through the air inlet 11, the dry air passes through the humidification component 20, becoming humidified, and then the humidified air is blown out from the air outlet 12.

[0038] A first fan 30 is provided between the air outlet 12 and the humidification component 20. When the first fan 30 is turned on, it can guide the air, so that the air in the external environment can be drawn into the housing 10 from the air inlet 11, humidified by the humidification component 20, and then blown out from the air outlet 12.

[0039] Meanwhile, a second fan 40 is provided between the air inlet 11 and the humidification component 20, and a heating element 50 is provided on the humidification component 20. The second fan 40 and the heating element 50 are used to dry the residual water on the humidification component 20 after the mist-free humidifier 100 has finished humidifying.

[0040] Specifically, after humidification is complete, the heating element 50 can be turned on first to generate heat. At this time, the first fan 30 and the second fan 40 are turned on simultaneously. The second fan 40 blows air upward toward the humidification component 20, and the first fan 30 guides the airflow downward to form a convection warm air circulation inside the housing 10.

[0041] In this way, with the combined action of the first fan 30, the second fan 40 and the heating element 50, the warm airflow can pass through the humidification component 20 evenly and dry the humidification component 20 evenly.

[0042] Thus, through the synergistic effect of the first fan 30, the second fan 40, and the heating element 50, a convection warm air circulation is formed on the upper and lower sides of the humidification component 20, allowing heat to pass through the humidification component 20 more evenly, thereby ensuring that the humidification component 20 is fully dried and effectively reducing the probability of bacterial growth.

[0043] In some embodiments, the housing 10 has a top wall 13, a bottom wall 14, and a side wall 15, with the top wall 13 and the bottom wall 14 disposed opposite each other, and the side wall 15 surrounding the top wall 13 and the bottom wall 14. An air inlet 11 is formed on the side wall 15 and close to the bottom wall 14, and an air outlet 12 is formed on the top wall 13. A second fan 40 is fixed to the bottom wall 14 and is positioned towards the humidification assembly 20.

[0044] Specifically, the top wall 13 and bottom wall 14 of the housing 10 are both horizontally arranged and spaced apart from each other in the vertical direction, and the side wall 15 surrounds the outer periphery of the top wall 13 and bottom wall 14.

[0045] Furthermore, the air inlet 11 is located on the side wall 15, so that the air inlet 11 is arranged around the periphery of the housing 10, which can effectively increase the air intake area. At the same time, the air inlet 11 is located near the bottom wall 14, that is, the air inlet 11 is located at the bottom of the housing 10, and the air outlet 12 is located on the top wall 13.

[0046] In this way, external air enters the housing 10 through the air inlet 11 at the bottom, and then, under the action of the first fan 30, passes through the humidification component 20 from bottom to top, is humidified, and then blown out from the air outlet 12 at the top.

[0047] Furthermore, the second fan 40 is fixed to the bottom wall 14 and positioned towards the humidification assembly 20. Thus, the first fan 30 is located above the humidification assembly 20, and the second fan 40 is located below it. After the mist-free humidifier 100 finishes humidifying, the first fan 30 and the second fan 40 can smoothly form a convection warm air circulation on both the upper and lower sides of the humidification assembly 20, achieving the drying of the humidification assembly 20.

[0048] Understandably, a motor can be installed on the bottom wall 14, and the motor is connected to the second fan 40 to drive the second fan 40 to rotate. Of course, when the second fan 40 is set on the bottom wall 14, a sealing structure can be set between the second fan 40 and the bottom wall 14, for example, by using high-temperature silicone or other sealing rings to achieve a sealed connection between the second fan 40 and the bottom wall 14.

[0049] Thus, through the above structure, the first fan 30 and the second fan 40 can smoothly form a convection warm air circulation on the upper and lower sides of the humidification component 20, thereby achieving efficient drying of the humidification component 20.

[0050] In some embodiments, the humidification assembly 20 includes an evaporative cooling pad 21 and a distributor 22 for distributing water onto the evaporative cooling pad 21. The evaporative cooling pad 21 is located below the distributor 22 along the direction of gravity and is fixed to the side wall 15, and the evaporative cooling pad 21 overlaps with at least a portion of the air inlet 11. A heating element 50 is disposed on the distributor 22.

[0051] Specifically, the evaporative cooling pad 21 is fixed to the side wall 15 and overlaps with at least a portion of the air inlet 11. In this way, when dry air from the external environment enters the air inlet 11, it passes through the evaporative cooling pad 21, thereby humidifying the air.

[0052] Furthermore, the water distributor 22 is positioned above the evaporative cooling pad 21, meaning that the evaporative cooling pad 21 is located below the water distributor 22 along the direction of gravity. In this way, the water on the water distributor 22 can be evenly distributed onto the evaporative cooling pad 21 below it under the action of gravity, thus fully wetting the evaporative cooling pad 21.

[0053] In addition, the heating element 50 is installed on the liquid distributor 22. After humidification is completed, the heat generated by the heating element 50 is evenly transferred to the wet curtain 21 under the convection of the first fan 30 and the second fan 40, so that the wet curtain 21 can be fully dried.

[0054] Understandably, the heating element 50 is placed on the liquid distributor 22 so that the heating element 50 can maintain a certain distance from the wet curtain 21, thus avoiding direct contact between the heating element 50 and the wet curtain 21 and causing damage.

[0055] Thus, through the above structure, on the one hand, the dry air outside can pass through the wet curtain 21 fully, thereby humidifying the air; on the other hand, while the heating element 50 transfers heat to the wet curtain 21, a certain distance is maintained between the heating element 50 and the wet curtain 21 to avoid direct contact between the heating element 50 and the wet curtain 21, thereby preventing damage.

[0056] In some embodiments, the mist-free humidifier 100 further includes a water tank 60 and a water pump 70. The water tank 60 is disposed inside the housing 10, and the water pump 70 is connected between the water tank 60 and the distributor 22 for drawing water from the water tank 60 to the distributor 22.

[0057] Specifically, the water tank 60 can be located at the bottom of the housing 10, that is, the bottom wall 14 of the water tank 60 forms the bottom wall 14 of the housing 10. The water tank 60 can be used to store water, and the water pump 70 is located on the bottom wall 14 of the water tank 60, with the water pump 70 connected between the water tank 60 and the water distributor 22. In use, the water pump 70 can draw water from the water tank 60 into the water distributor 22 above, and then the water is evenly distributed to the wet curtain 21 below through the water distributor 22, thus achieving a humidification effect.

[0058] Therefore, by setting up a water tank 60 and a water pump 70, the water storage function can be realized, and the water in the water tank 60 can be smoothly drawn into the distributor 22. Then, the water is evenly distributed to the wet curtain 21 below it through the distributor 22, thus achieving the humidification effect.

[0059] Please refer to the following: Figure 1 , Figure 2 as well as Figure 3 In some embodiments, the liquid distributor 22 is arranged around the side wall 15, and the liquid distributor 22 encloses and forms an installation space 23, and the heating element 50 is fixed in the installation space 23.

[0060] Specifically, the distributor 22 is configured as a ring structure and is arranged around the side wall 15. In this way, the distributor 22 matches the wet curtain 21, and the distributor 22 can evenly distribute the water flow onto the wet curtain 21 below it.

[0061] Furthermore, an installation space 23 is formed at the center of the liquid distributor 22, and the heating element 50 is fixed within the installation space 23. Thus, during drying, the airflow can smoothly pass through the heating element 50 under the coordinated action of the first fan 30 and the second fan 40, thereby forming a convective warm air circulation to dry the wet curtain 21.

[0062] In addition, the first fan 30 and the second fan 40 work together to allow the heat generated by the heating element 50 to pass through the wet curtain 21 quickly and evenly, which can also create a good drying effect for the wet curtain 21, which has a large area and a thick thickness.

[0063] Thus, through the above structure, the heating element 50 can cooperate with the first fan 30 and the second fan 40 to form a convective warm air circulation, so that the hot airflow can pass through the wet curtain 21 evenly and achieve a good drying effect on the wet curtain 21.

[0064] In some embodiments, a plurality of support members 24 extending toward the installation space 23 are provided on the inner peripheral wall of the liquid distributor 22. Each support member 24 is spaced apart along the circumference of the liquid distributor 22. The heating element 50 is supported on each support member 24 and is detachably connected to each support member 24.

[0065] Specifically, multiple support members 24 are protruding from the inner peripheral wall of the liquid distributor 22. Each support member 24 extends toward the installation space 23 and is evenly and spaced apart along the circumference of the liquid distributor 22.

[0066] Furthermore, the heating element 50 can be configured as a circular structure, and multiple overlapping portions can be formed on the outer periphery of the heating element 50, with each overlapping portion corresponding to a support member 24. At the same time, screw posts are provided on each support member 24, and screw holes are provided on each overlapping portion.

[0067] In this way, each overlapping part can be supported on a corresponding support member 24, and then the corresponding overlapping part is connected and fixed to the support member 24 by screws.

[0068] Understandably, other methods can also be used to achieve detachable connection between each overlapping part and the support member 24, such as using slots and buckles to achieve the connection and fixation between the two, which will not be elaborated here.

[0069] The above structure enables a fixed connection between the heating element 50 and the liquid distributor 22, allowing the heating element 50 to be more stably installed inside the housing 10, thereby achieving the drying of the humidification component 20.

[0070] In some embodiments, the heating element 50 is configured as a waterproof PTC heating element.

[0071] Specifically, the waterproof PTC heating element can be, but is not limited to, a PTC ceramic heating element. PTC ceramic heating elements have self-regulating temperature characteristics, which can effectively reduce the risk of overheating. Furthermore,

[0072] Therefore, by setting a waterproof PTC heating element, heat can be smoothly generated inside the housing 10, and in conjunction with the first fan 30 and the second fan 40, convective warm air circulation is formed on the upper and lower sides of the wet curtain 21 to achieve the drying effect.

[0073] In some embodiments, the mist-free humidifier 100 further includes a temperature sensor (not shown) disposed inside the housing 10, which is used to detect the drying temperature inside the housing 10.

[0074] Specifically, during the drying process, the actual temperature inside the housing 10 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 heating element 50, or overheating of the heating element 50. The drying process can be adjusted in time to make the drying process smoother and safer.

[0075] Therefore, by setting a temperature sensor, the drying process can be better controlled, making the drying process smoother and safer.

[0076] In some embodiments, the mist-free humidifier 100 further includes a humidity sensor (not shown) disposed inside the housing 10, which is used to detect the dryness of the humidification assembly 20.

[0077] Specifically, the humidity sensor can detect the drying status of the wet curtain 21 in real time during the drying process, so as to better adjust the drying process.

[0078] In some embodiments, the mist-free humidifier 100 further includes a timer (not shown) disposed inside the housing 10. The timer is electrically connected to the first fan 30, the second fan 40 and the heating element 50 respectively, and is used to start and stop the first fan 30, the second fan 40 and the heating element 50 at regular intervals.

[0079] Specifically, the timer can be electrically connected to the first fan 30, the second fan 40 and the heating element 50 respectively. In this way, the timer can better control the opening and closing of the first fan 30, the second fan 40 and the heating element 50, thereby better controlling the drying time and adjusting the drying process.

[0080] According to one or more embodiments, when the mist-free humidifier 100 performs the humidification task, the water in the water tank 60 is first drawn into the upper liquid distributor 22 by the water pump 70, and then the water is evenly distributed to the wet curtain 21 below by the liquid distributor 22, so that the wet curtain 21 is fully wetted.

[0081] Subsequently, the first fan 30 is activated, drawing in ambient air through the air inlet 11 and passing it over the surface of the wet curtain 21. As the air passes through the wet curtain 21, the moisture on the wet curtain 21 is naturally evaporated and enters the airflow, then is blown out through the air outlet 12, thereby increasing the humidity of the ambient air.

[0082] After the mist-free humidifier 100 completes its humidification task, the heating element 50, the first fan 30, and the second fan 40 can be turned on simultaneously. The heating element 50 generates heat to heat the air. At the same time, the second fan 40 blows air from bottom to top, and the first fan 30 guides the airflow downwards, forming a convective warm air circulation inside the housing 10. At this time, the heat generated by the heating element 50 can quickly and evenly pass through the evaporative cooling pad 21 under the action of the airflow, so that the evaporative cooling pad 21 is dried evenly.

[0083] 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.

[0084] 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.
