[0044] In the prior art, a humidifier generally has a roller humidification device provided to humidify the room through the roller humidification device. For example, the utility model patent with the application number 202121046326.X discloses an inner tank structure of a mist-free humidifier, including an inner tank main body, a hot air component for generating hot air, a water film component for generating a water film, and a water storage tank for storing water; the hot air component is arranged on the inner tank main body and communicates with the lower part of the inner cavity of the inner tank main body; the water film component is arranged in the lower part of the inner cavity of the inner tank main body. The roller water film component is used to adsorb the water in the water tank and bring the water into the evaporation chamber. The hot air component can heat the roller water film component to increase the evaporation speed of the water on the water film, thereby realizing the humidification of the room.

[0045] However, for the above humidifier provided with a roller water film component, generally, aluminum foil is used to make the water film and the aluminum foil is wound around the roller, and the humidification amount of the humidification method is small, and the user experience is not good.

[0046] As Figures 1 to 6 shown, the embodiments of the present disclosure provide a humidifier. The roller assembly 20 can rotate in the water tank 10 and bring water into the evaporation box body through the water absorption member 60. At the same time, the heating device 30 can be turned on to heat the water in the water tank 10 to increase the evaporation speed of the water, thereby improving the humidification amount of the humidifier and improving the user experience.

[0047] As Figures 1 to 6As shown in the figure, an embodiment of the present disclosure provides a humidifier, which includes a housing, a water tank 10, a humidifying device, and a heating device 30. The housing is provided with an installation cavity and an evaporation cavity; the water tank 10 is arranged in the installation cavity, and the water tank 10 is provided with a water storage part for storing water; the humidifying device includes a roller assembly 20 and a water absorption member 60, the roller assembly 20 is rotatably arranged in the water tank 10, and the water absorption member 60 is installed on the roller assembly 20; the heating device 30 is arranged in the water tank 10 for heating the water in the water storage part; wherein, the water absorption member 60 is at least partially located in the water storage part, and the water absorption member 60 is at least partially located in the evaporation cavity.

[0048] Specifically, the housing is further provided with an air outlet and an air return opening, and the air outlet and the air return opening are respectively communicated with the evaporation cavity through air ducts. A damper is arranged in the air duct, and the damper can dredge or block the air duct. A fan is also arranged in the air duct, and the air supply direction of the fan is defined as facing the air outlet. The water tank 10 is horizontally installed in the installation cavity of the housing, and an opening is provided on the upper end surface of the water tank 10. The size of the opening of the water tank 10 is larger than the size of the roller assembly 20, so that the roller assembly 20 can be horizontally installed in the water tank 10 through the opening. The driving device 50 is a motor, and the motor is fixedly installed on the housing. The roller assembly 20 is provided with a rotating shaft, the motor is provided with an output end, and the output end of the motor is drivingly connected to the rotating shaft of the roller assembly 20 to drive the roller assembly 20 to rotate. The evaporation cavity is located above the water tank 10, at least part of the roller assembly 20 is located in the water storage part, and at least part of the roller assembly 20 is located in the evaporation cavity.

[0049] In the case of turning on the dehumidification mode, the damper is opened to dredge the air duct. Indoor air can flow into the air duct through the air return opening and flow to the evaporation cavity through the air duct. At this time, the motor can drive the roller assembly 20 to rotate, and then drive the water absorption member 60 wound around the roller assembly 20 to move between the water storage part and the evaporation cavity. The water absorption member 60 located in the water storage part can adsorb the moisture in the water storage part and move to the evaporation cavity under the drive of the roller assembly 20. At this time, the moisture in the water absorption member 60 in the evaporation cavity evaporates in the evaporation cavity to humidify the air in the evaporation cavity. After the air in the evaporation cavity is humidified, the fan can blow the humid air in the evaporation cavity into the room to humidify the room. After the moisture in the water absorption member 60 in the evaporation cavity evaporates, the roller assembly 20 can drive the water absorption member 60 in the evaporation cavity to move to the water storage part so that the water absorption member 60 can adsorb moisture again. At the same time, in the case of a large required humidification amount, the user can also turn on the heating device 30 to heat the water in the water tank 10 to increase the evaporation speed of the moisture, thereby increasing the humidification amount of the humidifier and improving the user experience.

[0050] In practical applications, the ratio of the volume of the water-absorbing member 60 located in the water storage part to the volume located in the evaporation cavity can be set according to actual needs. For example, 1 / 2 of the water-absorbing member 60 is located in the water storage part, and 1 / 2 of the water-absorbing member 60 is located in the evaporation cavity; or, 1 / 3 of the water-absorbing member 60 is located in the water storage part, and 2 / 3 of the water-absorbing member 60 is located in the evaporation cavity; or, 2 / 3 of the water-absorbing member 60 is located in the water storage part, and 1 / 3 of the water-absorbing member 60 is located in the evaporation cavity. By setting it in this way, the water absorption amount and evaporation amount can be adjusted by adjusting the time of the water-absorbing member 60 in the water storage part and the evaporation cavity.

[0051] In practical applications, the user can also adjust the number of turns of the water-absorbing member 60 wound around the roller assembly 20, thereby improving the humidifying efficiency of the humidifier.

[0052] Optionally, the water tank 10 is detachably arranged in the installation cavity. The humidifier is also provided with a water level sensor 41 and a warning device. The water level sensor 41 is used to obtain the water volume in the water storage part, and the water level sensor 41 is electrically connected to the warning device. When the water volume in the water storage part is lower than or equal to the first preset water volume, the water level sensor 41 can trigger the warning device to remind the user that the humidifier is in a low water volume state. At this time, the user can take out the water tank 10 from the installation cavity and add water to the water tank 10 to avoid affecting the humidifying efficiency of the humidifier.

[0053] In the above embodiment, when the water level sensor 41 detects that the water level height in the water storage part is lower than the height of the roller assembly 20, the water level sensor 41 determines that the humidifier is in a low water volume state and triggers the warning device. Among them, the height of the roller assembly 20 refers to the distance between the roller assembly 20 and the bottom surface of the water storage part.

[0054] As Figure 2 shown, in some embodiments, the heating device 30 is an electric heating element.

[0055] Specifically, the humidifying and dehumidifying integrated machine is also provided with a power supply device, and the power supply device is electrically connected to the electric heating element. The power supply device can supply power to the electric heating element to make the electric heating element generate heat.

[0056] Optionally, the heating device 30 is a PTC heating element.

[0057] It can be understood that the PTC heating element is also called a PTC heater, which is composed of a PTC ceramic heating element and an aluminum tube. This type of PTC heating element has the advantages of small thermal resistance and high heat exchange efficiency, and is an automatic constant temperature and power-saving electric heating element.

[0058] As Figure 2As shown, in some embodiments, the humidifier further includes: a temperature sensor 42. The temperature sensor 42 is disposed in the water tank 10 and is used to obtain the temperature of the water in the water storage part; wherein, the temperature sensor 42 is electrically connected to the heating device 30; when the temperature of the water in the water storage part is greater than or equal to a first preset temperature, the temperature sensor 42 controls the heating device 30 to turn off.

[0059] Specifically, the first preset temperature is greater than or equal to 40°C. For example, the first preset temperature can be 40°C, that is, when the temperature of the water in the water storage part is greater than or equal to 40°C, the temperature sensor 42 controls the heating device 30 to turn off; the first preset temperature can also be 45°C, that is, when the temperature of the water in the water storage part is greater than or equal to 45°C, the temperature sensor 42 controls the heating device 30 to turn off; or, the first preset temperature can also be 50°C, that is, when the temperature of the water in the water storage part is greater than or equal to 50°C, the temperature sensor 42 controls the heating device 30 to turn off. By setting like this, it can avoid the water temperature in the water tank 10 from being too high, thereby affecting other components of the humidifier.

[0060] As Figure 2 shown, in some embodiments, the humidifier includes a plurality of heating devices 30, and the plurality of heating devices 30 are evenly distributed on the bottom wall surface of the water tank 10.

[0061] Specifically, the plurality of heating devices 30 are respectively electrically connected to the power supply device, and the plurality of heating devices 30 can be individually turned on or off. In this way, the user can control the temperature of the water in the water tank 10 by controlling the number of the turned-on heating devices 30, and further control the humidification amount of the humidifier.

[0062] It can be understood that by evenly distributing the plurality of heating devices 30 on the bottom wall surface of the water tank 10, the water in the water tank 10 can be heated evenly, so as to improve the heating efficiency.

[0063] As Figure 1 and Figure 2 shown, in some embodiments, the roller assembly 20 includes an inner frame 21 rotatably disposed in the water tank 10 and an outer frame 22 covering the inner frame 21. There is a gap between the inner frame 21 and the outer frame 22 to form an installation gap, and the outer frame 22 is provided with through holes; wherein, the water absorption member 60 is installed in the installation gap.

[0064] Specifically, the inner skeleton 21 is cylindrical. A base 211 is provided at the first end of the inner skeleton 21, and a rotating shaft is provided on the outer end face of the base 211. The edge of the base 211 extends outward and is connected to the outer skeleton 22 to seal one end of the installation gap. The driving device 50 can drive the inner skeleton 21 to rotate, thereby driving the water absorption member 60 to move between the water storage part and the evaporation cavity. The size of the outer skeleton 22 is larger than that of the inner skeleton 21, and the outer skeleton 22 is a hollow cylindrical structure. After the water absorption member 60 is wound around the inner skeleton 21, the outer skeleton 22 can be sleeved outside the inner skeleton 21 and the water absorption member 60, and there is an installation gap between the outer skeleton 22 and the inner skeleton 21 for making way for the water absorption member 60. This setting can prevent the water absorption member 60 from falling off the roller assembly 20. Among them, the water in the water storage part can flow into the installation gap through the through holes of the outer skeleton 22, so that the water is adsorbed by the water absorption member 60.

[0065] Optionally, the outer skeleton 22 is detachably installed on the inner skeleton 21. For example, the outer skeleton 22 can be installed on the inner skeleton 21 by means of snap connection, bonding or screwing. This setting makes it more convenient to install or remove the water absorption member 60 after the outer skeleton 22 is detached from the inner skeleton 21.

[0066] As Figure 6 shown, in some embodiments, at least part of the water absorption member 60 is wavy; among them, when multiple layers of wavy water absorption members 60 are wound around the outer side of the inner skeleton 21, the positions of the peaks and valleys of the outer layer of wavy water absorption members 60 correspond to the positions of the peaks and valleys of the inner layer of wavy water absorption members 60 respectively.

[0067] Specifically, when multiple layers of wavy water absorption members 60 are wound around the inner skeleton 21, the positions of the peaks and valleys of the multiple layers of water absorption members 60 correspond to each other. This setting can reduce the occupied position of the water absorption member 60. At the same time, setting the water absorption member 60 in a wavy shape can enable it to adsorb more water, thereby increasing the humidification efficiency.

[0068] As Figure 6 shown, in some practical applications, the humidifier is provided with a first water absorption member 60, a second water absorption member 60 and a third water absorption member 60. The first water absorption member 60 and the third water absorption member 60 are flat structures, and the second water absorption member 60 is a wavy structure. Among them, the first water absorption member 60, the second water absorption member 60 and the third water absorption member 60 are wound around the inner skeleton 21 in sequence. In this way, the inner skeleton 21 contacts the first water absorption member 60 to increase the contact area between the water absorption member 60 and the inner skeleton 21; the outer skeleton 22 contacts the third water absorption member 60 to increase the contact area between the water absorption member 60 and the outer skeleton 22. At the same time, the wavy second water absorption member 60 between the first water absorption member 60 and the third water absorption member 60 can also adsorb more water.

[0069] In practical applications, the thickness of the wavy water absorbent member 60 can be set according to the height of the installation gap. Among them, the thickness of the wavy water absorbent member 60 refers to the distance between the horizontal plane where the peak is located and the horizontal plane where the valley is located.

[0070] As Figures 3 to 5 shown, in some embodiments, the outer skeleton 22 is cylindrical, and one end of the outer skeleton 22 is provided with an opening; the humidifier further includes: an end cap 23. The end cap 23 is detachably installed at the opening of the outer skeleton 22.

[0071] Specifically, the opening of the outer skeleton 22 is located at the second end of the inner skeleton 21. After installing the outer skeleton 22 on the inner skeleton 21, the end cap 23 can be directly removed from the opening, and then the water absorbent member 60 can be installed or removed from the installation gap through the opening. With this setting, the user can install or remove the water absorbent member 60 without disassembling the outer skeleton 22, further improving the user experience.

[0072] As Figure 5 shown, in some embodiments, the outer skeleton 22 includes a plurality of support bars 221 arranged axially, and the plurality of support bars 221 are circumferentially enclosed outside the inner skeleton 21; among them, the distance between adjacent support bars 221 is greater than or equal to a first preset distance, and the gaps between the support bars 221 form through holes.

[0073] Specifically, the first ends of the plurality of support bars 221 are sequentially and uniformly fixedly installed on the base 211 of the inner skeleton 21, and the other ends extend parallel to the inner skeleton 21 towards the other end. The plurality of support bars 221 are arranged in a form of enclosing the inner skeleton 21, and there is a gap between the support bars 221 and the inner skeleton 21 to form an installation gap. Among them, the distance between two adjacent support bars 221 is greater than or equal to the first preset distance to form through holes, thereby increasing the amount of water flowing into the installation gap.

[0074] As Figure 5 shown, in some embodiments, the outer skeleton 22 further includes a reinforcing ring 222, and the reinforcing ring 222 is used to connect the plurality of support bars 221.

[0075] Specifically, the plurality of support bars 221 are connected by the reinforcing ring 222 to prevent the support bars 221 from shaking, thereby increasing the strength of the outer skeleton 22.

[0076] As Figure 5 shown, in some embodiments, the outer skeleton 22 is provided with a plurality of reinforcing rings 222, and the plurality of reinforcing rings 222 are arranged axially; among them, the distance between adjacent reinforcing rings 222 is greater than or equal to a second preset distance.

[0077] Specifically, by connecting multiple support bars 221 through multiple reinforcing rings 222 respectively, the strength of the outer skeleton 22 can be further increased. Meanwhile, making the distance between adjacent reinforcing rings 222 greater than or equal to a second preset distance can prevent the reinforcing rings 222 from interfering with the amount of water flowing into the installation gap.

[0078] As Figure 2 shown, in some embodiments, the humidifier further includes: a water pump 11. The water pump 11 is disposed inside the water tank 10 or in the installation cavity, and is used for sending water into the water tank 10 or pumping the water in the water tank 10 out.

[0079] Specifically, the water pump 11 is electrically connected to the water level sensor 41. When the water volume in the water storage part is lower than or equal to a first preset water volume, the water level sensor 41 can trigger the water pump 11. At this time, the water pump 11 can automatically inject water into the water storage part, and the operation is more convenient, further improving the user experience. When the water volume in the water storage part is higher than or equal to a second preset water volume, the water level sensor 41 can trigger the water pump 11. At this time, the water pump 11 can pump the water in the water storage part out to prevent the water from overflowing outside the water tank 10.

[0080] In the above embodiments, when the water level sensor 41 detects that the water level height in the water storage part is lower than the height of the roller assembly 20, the water level sensor 41 determines that the humidifier is in a low water volume state and triggers the water pump 11 to make the water pump 11 inject water into the water storage part. When the water level sensor 41 detects that the water level in the water storage part is higher than 3 / 4 of the height of the water tank 10, the water level sensor 41 determines that the humidifier is in a high water volume state and triggers the water pump 11 to make the water pump 11 pump the water in the water storage part out. Wherein, the height of the roller assembly 20 refers to the distance between the roller assembly 20 and the bottom surface of the water storage part.

[0081] The above description and the drawings fully illustrate the embodiments disclosed in the present application, so that those skilled in the art can practice them. Other embodiments may include structural and other changes. The embodiments only represent possible variations. Unless explicitly required, the individual components and functions are optional, and the order of operations can vary. Some parts and features of some embodiments can be included in or replaced by parts and features of other embodiments. The embodiments disclosed in the present application are not limited to the structures described above and shown in the drawings, and various modifications and changes can be made without departing from its scope. The scope of the present disclosure is only limited by the appended claims.
