Description

Technical Field

[0001] The present application relates to the technical field of humidifiers, and in particular to a fog-free humidifier. Background Art

[0002] Cold evaporative mistless humidifiers reduce dryness by allowing water to evaporate naturally into the outside air. The filter components of current mistless humidifiers are either immersed in a water tank, which keeps the filter components moist for a long time, making them prone to mold and bacteria; or they are separated from the water tank and the filter components are dried by extending the working time of the fan. The disadvantage of these two types of mistless humidifiers is that the filter components cannot be effectively dried, and the filter components are still in an environment suitable for the growth of mold and other bacteria, so that they will mold and even produce unhealthy moisture.

[0003] In order to solve the above problems, for example, the Chinese utility model patent with publication number CN219913304U discloses a filter element drying device for a fogless humidifier, which discloses that the humidification filter element is driven to rotate by a rotary drive mechanism so that the water remaining on the humidification filter element is separated from the humidification filter element, thereby making the humidification filter element in a relatively dry state. However, it realizes its function by driving the wind wheel and the filter net to move respectively by two motors, and the structure is relatively complex and the cost is high. Utility Model Content

[0004] In view of the above problems, the purpose of the embodiments of the present application is to provide a fog-free humidifier to solve the problem of high structural cost of the spin-drying filter assembly.

[0011] When the mistless humidifier is required to realize the humidification function, the power source drives the output shaft to rotate in the first direction, so that the second output end of the output shaft drives the wind wheel to rotate, so that the moisture entering from the air inlet and formed after humidification through the filter assembly is discharged along the air duct and the air outlet, and the filter assembly is disconnected from the first output end and will not rotate when the first output end rotates; when the mistless humidifier is required to realize the function of drying the filter assembly, the power source drives the output shaft to rotate in the second direction, and the second output end of the output shaft rotates and drives the wind wheel to rotate, while the switching assembly connects the filter assembly and the first output end together, and the filter assembly rotates together with the first output end, and the moisture on the filter assembly is thrown off the filter assembly under the action of centrifugal force, so that the filter assembly is dry and the filter assembly is prevented from getting moldy.

The shape of the air duct can ensure that the outside air can move smoothly along the humidification route under the action of the wind wheel, and can also effectively utilize the space in the fuselage without affecting the arrangement of other components.

[0045] The above and other aspects, features and advantages of the present application will become more apparent in view of the following detailed description when taken in conjunction with the accompanying drawings.

[0046] Specific embodiments of the present application are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments applied for are merely examples of the present application, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that obscure the present application. Therefore, the specific structural and functional details applied for herein are not intended to be limiting, but merely serve as a basis and representative basis for the claims to teach those skilled in the art to use the present application in a variety of ways with substantially any suitable detailed structure.

[0047] This specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," all of which may refer to one or more of the same or different embodiments according to the present application.

[0048] The present application embodiment provides a fog-free humidifier, such as Figure 1-Figure 6 As shown, the mistless humidifier includes a body, a power source 4, a filter assembly 51, a wind wheel 6 and a switching assembly 7.

[0049] The fuselage is provided with an air outlet 14 and an air inlet 15, an air duct is provided between the air outlet 14 and the air inlet 15, and a water tank assembly 31 is also provided in the fuselage. The power source 4 is provided in the air duct and has an output shaft 41, and the two ends of the output shaft 41 respectively form a first output end 411 and a second output end 412. The specific structural form of the power source 4 is not limited, for example, a motor can be used.

[0050] The filter assembly 51 is moistened by the water source provided by the water tank assembly 31, so that the outside air entering from the air inlet 15 and flowing through the filter assembly 51 becomes humid. The wind wheel 6 is connected to the second output end 412 and can move with the rotation of the output shaft, so as to discharge the moisture in the fuselage to the outside through the air duct and the air outlet 14.

[0051] The switching assembly 7 is arranged between the first output end 411 and the filter assembly 51, and is used to connect the filter assembly 51 with the first output end 411 when the output shaft 41 rotates along the first direction, so that the filter assembly 51 rotates along the first direction driven by the output shaft 41 to dehydrate. The switching assembly 7 is also used to disengage the filter assembly 51 from the first output end 411 when the output shaft 41 rotates along the second direction, wherein the first direction and the second direction are opposite directions.

[0052] When the mistless humidifier is needed to realize the humidification function, the power source 4 drives the output shaft 41 to rotate in the first direction, so that the second output end 412 of the output shaft 41 drives the wind wheel 6 to rotate, thereby the moisture entering through the air inlet 15 and formed after humidification by the filter assembly 51 is discharged along the air duct and the air outlet 14, while the filter assembly 51 is disengaged from the first output end 411 and will not rotate when the first output end 411 rotates.

[0053] When the mistless humidifier is required to realize the function of drying the filter assembly 51, the power source 4 drives the output shaft 41 to rotate along the second direction, and the second output end 412 of the output shaft 41 rotates and drives the wind wheel 6 to rotate. At the same time, the switching component 7 connects the filter assembly 51 and the first output end 411 together, and the filter assembly 51 rotates together with the first output end 411. The moisture on the filter assembly 51 is thrown away from the filter assembly 51 under the action of centrifugal force, so that the filter assembly 51 is dried and the filter assembly 51 is prevented from getting moldy. In the drying process, the wind wheel 6 can quickly discharge moisture to speed up the drying efficiency.

[0054] As an optional embodiment, Figure 1-Figure 2 As shown, the body includes a first shell 11 , a second shell 12 and a third shell 13 .

[0055] The air outlet 14 is provided at one end of the first housing 11, and the wind wheel 6 is disposed in the first housing 11. One end of the second housing 12 is connected to the other end of the first housing 11, and the air inlet 15 is provided on the side of the second housing, and the filter assembly 51 is disposed in the second housing 12. One end of the third housing 13 is connected to the other end of the second housing 12, and the water tank assembly 31 is disposed in the third housing 13.

[0056] The body is composed of a first shell 11, a second shell 12 and a third shell 13. The shells can be disassembled from each other, which is quick to install and convenient for maintenance. The filter assembly 51 is detachably assembled in the second shell 12, which is convenient for users to replace the filter, reduce the cost of use, and improve the user's stickiness and experience.

[0057] As an optional embodiment, Figure 2-Figure 3 As shown, the air duct includes an upper air duct 21 , a lower air duct 22 and a ring-shaped air duct 23 .

[0058] The upper air duct 21 is formed by the gap between the inner wall of the first housing 11 and the outer periphery of the wind wheel 6. The lower air duct 22 is formed by the inner space of the filter assembly 51 and is in communication with the upper air duct 21, wherein the filter assembly 51 is an annular column. The annular air duct 23 is formed by the gap between the inner wall of the second housing 12 and the outer periphery of the filter assembly 51 and is in communication with the lower air duct 22, so that the outside air can enter the lower air duct 22 through the air inlet 15, the annular air duct 23 and the filter assembly 51 in sequence under the action of the wind wheel 6.

[0059] The shape of the air duct is simple and reasonable, which can ensure that the outside air can move smoothly along the humidification route under the action of the wind wheel 6, and can also not affect the arrangement of other components, and effectively utilize the space in the fuselage.

[0060] As an optional embodiment, Figure 7 As shown, the switching assembly 7 includes a connecting sleeve 71 , a bidirectional bearing 72 and a one-way bearing 73 .

[0061] The connecting sleeve 71 is sleeved on the first output end 411 and includes a first end and a second end opposite to the first end. The first end is connected to the first output end 411 via a bidirectional bearing 72, and the second end is connected to the first output end 411 via a one-way bearing 73. The one-way bearing 73 is used to connect the filter assembly 51 to the first output end 411 when the output shaft 41 rotates along the first direction, so that the filter assembly 51 can rotate along the first direction driven by the output shaft 41. The one-way bearing 73 is also used to disengage the filter assembly 51 from the first output end 411 when the output shaft 41 rotates along the second direction, so that the filter assembly 51 does not rotate along the second direction with the output shaft 41.

[0062] like Figure 8 As shown, the one-way bearing 73 includes an inner ring, an outer ring, a roller and a locking block. Based on the rolling friction of the roller, when the outer ring applies a rotational torque, the roller will be acted upon by the force and start to roll. The rolling of the roller will generate a reaction force, causing the inner ring to also start to rotate. When the outer ring stops rotating, the roller will immediately stop rolling, and the inner ring will also stop rotating, so that the roller can only roll in one direction, but not in the other direction. The structure and working principle of the one-way bearing 73 are technical means known to those skilled in the art, and therefore will not be described in detail in this application.

[0063] That is, the first output end 411 cooperates with the inner ring of the one-way bearing 73, and the first output end 411 can rotate on the inner ring of the one-way bearing 73, but the connecting sleeve 71 does not rotate, and the filter assembly 51 does not rotate.

[0064] Through the arrangement of the one-way bearing 73, the switching assembly 7 can only rotate in one direction, that is, when the output shaft 41 rotates in the second direction, the switching assembly 7 can only rotate around the output shaft 41 through the one-way bearing 73, and the filter assembly 51 does not rotate at this time. When the output shaft 41 rotates in the reverse direction (rotates in the first direction), the switching assembly 7 can lock the first output end 411 through the internal structure of the one-way bearing 73, and the switching assembly 7 rotates with the output shaft 41. Because the switching assembly 7 is connected to the filter assembly 51, the filter assembly 51 is driven to rotate.

[0065] As an optional embodiment, Figure 3 As shown, a filter bracket 52 for mounting the filter assembly 51 is provided in the second shell 12 , and a connecting seat 53 is provided in the inner space of the filter assembly 51 . One end of the connecting seat 53 is movably connected to the filter bracket 52 , and the other end thereof is snap-connected to the connecting sleeve 71 .

[0066] The connecting sleeve 71 is an outer hexagonal column, and the upper end of the connecting seat 53 is provided with an inner hexagonal groove, so that the connecting sleeve 71 and the connecting seat 53 cooperate with each other for transmission; the lower end of the connecting seat 53 is provided with an axial hole, and the filter bracket 52 is provided with a fixed shaft, and the axial hole rotates around the fixed shaft. Through a simple and reasonable structural layout, the filter assembly 51 and the filter bracket 52 are connected together without affecting the function of the spin-drying filter assembly 51.

[0067] As an optional embodiment, Figure 3 As shown, the first output end 411, the second output end 412, the connecting sleeve 71 and the connecting seat 53 are coaxially arranged. In this way, the filter assembly 51 can be easily disassembled during assembly and can be smoothly rotated in the second housing 12 to reduce the vibration of the whole machine caused by uneven concentricity of the axis.

[0068] As an optional embodiment, Figure 7 As shown, a clamping spring 42 is provided on the first output end 411 to limit the installation position of the connecting sleeve 71 on the first output end 411. This facilitates the user to determine the installation position of the switching assembly 7 and improves work efficiency.

[0069] As an optional embodiment, Figure 2 As shown, an air guide hood 18 is provided in the first housing 11, and one end of the air guide hood 18 extends to the end surface of one end of the first housing 11 where the air outlet 14 is provided, and the air guide hood 18 is used to guide the moisture drawn out by the wind wheel 6 to the air outlet 14 for discharge. The air guide hood 18 can help evenly distribute the moisture in the external environment, ensuring a more uniform and comprehensive humidification effect.

[0070] As an optional embodiment, Figure 2 and Figure 6 As shown, a water pump bracket 32 ​​is provided in the third shell 13, and a water pump 33 and a water supply pipe 34 connected to the water pump 33 are provided on the water pump bracket 32. The water pump 33 is used to transport the water in the water tank assembly 31 to the top of the filter assembly 51 through the water supply pipe 34 to humidify the filter assembly 51.

[0071] The third shell 13 is connected to the second shell 12 via a coupler so that current is conducted through the coupler. When the water pump 33 is working, the water in the water tank assembly 31 flows to the top of the filter assembly 51 through the water supply pipe 34, so that the water circulation completely wets the filter assembly 51.

[0072] As an optional embodiment, Figure 1 and Figure 3 As shown, the first housing 11 is provided with an operation panel 16 and a control panel 17 connected to the operation panel 16, and the control panel 17 is connected to the power source 4 and the water pump 33 respectively, and is used to control the opening and closing of the power source 4 and the water pump 33. After the user operates the operation panel 16, the control panel 17 controls whether the mistless humidifier humidifies or spins the filter assembly 51, which is flexible to use.

[0073] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims.
