Description

Technical Field

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

[0002] A humidifier is a household appliance that increases the humidity in a room. Humidifiers can be categorized into several types, including cold evaporation humidifiers, ultrasonic humidifiers, and electric heating humidifiers. Cold evaporation humidifiers typically use a wet curtain combined with a fan assembly. The fan assembly blows the tiny water droplets overflowing from the wet curtain outside the humidifier, thus humidifying the air.

[0003] However, the air outlet grille for the impeller assembly is usually non-removable, especially in floor-standing humidifiers, where the grille is typically installed above the impeller assembly. Consequently, dirt inevitably accumulates on the air outlet grille during long-term operation or when the humidifier is not in use, making cleaning difficult. Summary of the Invention

[0004] In view of the above problems, the present invention is proposed to provide a humidifier that overcomes or at least partially solves the above problems.

[0005] This invention provides a humidifier, the humidifier comprising:

[0006] The top cover is connected to the humidifier body of the humidifier. The top cover has an air outlet and a connecting groove, and the connecting groove is provided through the top cover towards the air outlet.

[0007] An air outlet cover, wherein the air outlet cover is located inside the air outlet hole;

[0008] A rotating assembly is installed between the air outlet cover and the upper cover to form a rotatable connection between the air outlet cover and the upper cover;

[0009] A spring hinge assembly is located on the end face of the air vent shroud away from the top cover and extends into the connecting groove. When the pulling force that drives the air vent shroud to flip away from the top cover is removed, the pressure force generated between the spring hinge assembly and the connecting groove causes the air vent shroud to return to its original position.

[0010] Optionally, the spring hinge assembly includes:

[0011] A positioning post is fixedly connected to the air outlet cover, wherein the positioning post is provided with mounting holes;

[0012] A spring is fitted into the mounting hole and press-fits against the positioning post, wherein one end of the spring extends onto the air outlet cover and contacts the air outlet cover; and...

[0013] The other end of the spring extends into the connecting groove so that when the air vent is flipped away from the top cover, the other end of the spring and the connecting groove make pressure contact.

[0014] Optionally, the spring includes a body fitted into the mounting hole, a first extension at one end of the body, and a second extension at the other end of the body; wherein,

[0015] The first extension contacts the air outlet cover, and the second extension extends into the connecting groove.

[0016] Optionally, the first extension and the second extension are arranged in parallel.

[0017] Optionally, the cross-sectional shape of the positioning post is an arc.

[0018] Optionally, the positioning post has a mounting ear extending from its outer end face away from the spring, and the mounting ear is fixedly connected to the air outlet cover by fasteners.

[0019] Optionally, the positioning post includes a first positioning part and a second positioning part, and the first positioning part and the second positioning part are shaped to fit together to form the mounting hole; wherein,

[0020] One side of the first positioning part and one side of the second positioning part are rotatably connected, and the other side of the first positioning part and the other side of the second positioning part are fixedly connected by fasteners so that the spring is pressed and fixed with the mounting hole.

[0021] Optionally, the cross-sectional shape of the first positioning part and the cross-sectional shape of the second positioning part are both semi-circular.

[0022] Optionally, the air outlet shroud includes:

[0023] The edge portion is clearance-fitted with the air outlet.

[0024] Multiple first support ribs and multiple second support ribs are staggered within the edge portion to form an air outlet grille.

[0025] Optionally, the width of the air outlet grille is less than or equal to a preset width threshold.

[0026] Compared with existing technologies, this invention includes a top cover, an air outlet cover, a rotating assembly, and a spring hinge assembly. The top cover is connected to the humidifier body of the humidifier. The top cover has an air outlet and a connecting groove, with the connecting groove extending through the top cover towards the air outlet. The air outlet cover is located within the air outlet. The rotating assembly is installed between the air outlet cover and the top cover, allowing the air outlet cover to be rotatably connected to the top cover. The spring hinge assembly is located on the end face of the air outlet cover away from the top cover and extends into the connecting groove. When the pulling force driving the air outlet cover to flip away from the top cover is removed, the pressure force generated between the spring hinge assembly and the connecting groove causes the air outlet cover to return to its original position. Therefore, when the air outlet cover or the fan needs cleaning, the user can open the air outlet cover to clean it, greatly reducing the difficulty of cleaning the humidifier.

[0027] The above description is merely an overview of the technical solution of the present invention.

[0039] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0040] The humidifiers disclosed in the following embodiments can include floor-standing humidifiers and wall-mounted humidifiers, depending on their placement. They are primarily cold evaporation humidifiers, also known as mist-free humidifiers. They utilize the principle of natural evaporation, where a fan 6 blows water from the wet curtain, accelerating the natural evaporation rate and allowing water molecules to naturally evaporate into the airflow channel within the humidifier body. Furthermore, the wet curtain filters impurities from the water, thus reducing the humidifier's water quality requirements. For example, tap water can be used directly for humidification without producing water mist, preventing floor and table wetness, and improving humidification efficiency. The humidifier has high product applicability. The humidifier may include a top cover 1, an air outlet cover 2, a rotating assembly 3, and a spring hinge assembly 4. The top cover 1 is connected to the humidifier body, and it has an air outlet 11 and a connecting groove 12, with the connecting groove 12 penetrating the top cover 1 towards the air outlet 11. The air outlet cover 2 is located inside the air outlet 11. The rotating assembly 3 is installed between the air outlet cover 2 and the upper cover 1, so that the air outlet cover 2 and the upper cover 1 are rotatably connected. The spring hinge assembly 4 is located on the end face of the air outlet cover 2 away from the upper cover 1 and extends into the connecting groove 12. When the pulling force that drives the air outlet cover 2 to flip away from the upper cover 1 is removed, the pressure force generated between the spring hinge assembly 4 and the connecting groove 12 causes the air outlet cover 2 to return to its original position. Thus, when the air outlet cover 2 or the fan wheel 6 needs to be cleaned, the user can open the air outlet cover 2 to clean it, greatly reducing the difficulty of cleaning the humidifier.

[0041] Reference Figure 1-8 This invention provides a humidifier, which may include an upper cover 1, an air outlet cover 2, a rotating assembly 3, and a spring hinge assembly 4, wherein:

[0042] The upper cover 1 is connected to the humidifier body of the humidifier. The upper cover 1 has an air outlet 11 and a connecting groove 12, with the connecting groove 12 penetrating through the upper cover 1 towards the air outlet 11. The air outlet shroud 2 is located within the air outlet 11. The rotating assembly 3 is installed between the air outlet shroud 2 and the upper cover 1, allowing the air outlet shroud 2 to be rotatably connected to the upper cover 1. The spring hinge assembly 4 is located on the end face of the air outlet shroud 2 away from the upper cover 1 and extends into the connecting groove 12. When the pulling force that drives the air outlet shroud 2 to rotate away from the upper cover 1 is removed, the pressure force generated between the spring hinge assembly 4 and the connecting groove 12 causes the air outlet shroud 2 to return to its original position.

[0043] In this embodiment of the invention, the humidifier body has an air guide channel, the impeller 6 is fixed in the air guide channel, and the upper cover 1 is located above the impeller 6 and fixed to the humidifier body. The upper cover 1 and the humidifier body can be detachably connected by snap-fit, threaded connection, or other methods to facilitate the assembly and disassembly of the upper cover 1. The impeller 6 is used to blow the high-humidity air in the air guide channel through the air outlet hood 2 installed on the upper cover 1 to the outside of the humidifier body, thereby humidifying the air in the external environment. The connecting groove 12 provides assembly space for the spring hinge assembly 4 on the upper cover 1, and it can be through-hole oriented towards the air outlet 11. In other words, at least one opening of the connecting groove 12 faces the air outlet 11. The spring 42 hinge assembly can include a spring 42, which mainly relies on the deformation restoring force of the spring 42 to reset the position of the air outlet hood 2.

[0044] In other words, the spring 42 extends into the connecting groove 12, and when the air outlet shroud 2 is in the closed state, such as Figure 1 and Figure 2 As shown, the hinge assembly of spring 42 is not under force, that is, the end of spring 42 extending into the connecting groove 12 does not generate pressure when in contact with the connecting groove 12, and spring 42 is in a free state. When the air outlet hood 2 is in the open state, as... Figure 3 As shown, when the air outlet cover 2 is driven to flip away from the upper cover 1, the end of the spring 42 extending into the connecting groove 12 presses against the connecting groove 12, generating a pressing force. The spring 42 is in a deformed state. After the driving force on the air outlet cover 2 is removed, the spring 42 can restore the air outlet cover 2 from the open state to the closed state due to its own deformation restoring force. Therefore, when the air outlet cover 2 or the fan wheel 6 needs to be cleaned, the user can open the air outlet cover 2 to clean it and the fan wheel 6. After cleaning, the air outlet cover 2 can be released. Then the air outlet cover 2 will automatically return to its original position, eliminating the need for disassembly and reassembly during the cleaning process. This greatly reduces the difficulty of cleaning the humidifier.

[0045] In one optional embodiment of the invention, reference is made to... Figure 3As shown, the spring hinge assembly 4 may further include a positioning post 41. The positioning post 41 is fixedly connected to the air outlet cover 2, and the positioning post 41 has a mounting hole 411. The spring 42 is sleeved in the mounting hole 411 and forms a pressure contact with the positioning post 41 for fixation. One end of the spring 42 extends onto the air outlet cover 2 and contacts the air outlet cover 2. The other end of the spring 42 extends into the connecting groove 12, so that when the air outlet cover 2 is flipped away from the upper cover 1, the other end of the spring 42 forms a pressure contact with the connecting groove 12.

[0046] In this embodiment of the invention, the positioning post 41 provides mounting space for the spring 42 on the air outlet cover 2. After the spring 42 is fitted into the mounting hole 411 of the positioning post 41, the positioning post 41 is then fixedly connected to the air outlet cover 2, thereby allowing the spring 42 and the positioning post 41 to form a pressure contact fixation, which serves to axially limit the spring 42. The air outlet cover 2 can be restored from an open state to a closed state by the radial deformation restoring force of the end of the spring 42 extending into the connecting groove 12.

[0047] In one optional embodiment of the invention, reference is made to... Figure 3 and Figure 5 As shown, the spring 42 may include a body 421 fitted into the mounting hole 411, a first extension 422 provided at one end of the body 421, and a second extension 423 provided at the other end of the body 421. The first extension 422 contacts the air outlet shroud 2, and the second extension 423 extends into the connecting groove 12.

[0048] In this embodiment of the invention, the body 421 has a spiral structure. The first extension 422 extends from one end of the body 421, radially extending along that end and contacting the air outlet hood 2. The second extension 423 extends from the other end of the body 421, radially extending along that end and contacting the connecting groove 12. Contact refers to the absence of pressure force. The body 421, the first extension 422, and the second extension 423 can be a single integrated structure. Therefore, the spiral structure of the body 421 provides the structural strength required to support the pressure deformation of the second extension 423, thereby improving the service life of the spring hinge assembly 4.

[0049] In one optional embodiment of the invention, reference is made to... Figure 3 and Figure 5 As shown, the first extension 422 and the second extension 423 are arranged in parallel.

[0050] In this embodiment of the invention, with the first extension 422 and the second extension 423 arranged in parallel, the upper surface of the air outlet hood 2 is flush with the bottom of the connecting groove 12. Thus, the first extension 422 and the upper cover 1 form surface contact when the air outlet hood 2 is in the closed state. Correspondingly, the second extension 423 and the upper cover 1 form surface contact when the air outlet hood 2 is in the closed state. Therefore, during the upward flipping process of the air outlet hood 2, the second extension 423 maintains constant pressure contact with the connecting groove 12, thereby obtaining maximum pressure force during the flipping stroke of the air outlet hood 2, so that the air outlet hood 2 can quickly rebound when the external pulling force is removed.

[0051] In one optional embodiment of the invention, reference is made to... Figure 6 As shown, the cross-sectional shape of the positioning post 41 is an arc shape.

[0052] In this embodiment of the invention, the cross-sectional shape of the positioning post 41 is designed to both increase the contact area with the spring 42 and reduce pressure damage to the spring 42. This ensures that the spring 42 is axially limited while maintaining its deformation performance.

[0053] In one optional embodiment of the invention, reference is made to... Figure 6 As shown, the positioning post 41 has a mounting ear 43 extending from its outer end face away from the spring 42, and the mounting ear 43 is fixedly connected to the air outlet cover 2 by fasteners 5.

[0054] In this embodiment of the invention, the fastener 5 may include, but is not limited to, screws, bolts, and other similar components. In some embodiments, the mounting ear 43 and the positioning post 41 may be an integral structure. The integral structure design facilitates the production of the mounting ear 43 and the positioning post 41, thereby improving the production efficiency of the positioning post 41. The mounting ear 43 and the air outlet cover 2 are provided with threaded holes for the fastener 5 to pass through, and the fastener 5 is threadedly connected to the threaded holes. Those skilled in the art can determine the number of mounting ears 43 according to actual design requirements, and no further limitations are made here. For example, there may be at least two mounting ears 43, such as two, three, or four. At least two mounting ears 43 may be distributed on both sides of the positioning post 41, thereby fixing the spring 42 through the mounting hole 11 formed by the positioning post 41 and the air outlet cover 2.

[0055] Therefore, when assembling the spring 42, first, the spring 42 is fitted into the mounting hole 411 of the positioning post 41, and then the positioning post 41 is fixed to the corresponding assembly position on the air outlet cover 2. Next, the fastener 5 is passed through the threaded hole and tightened until the positioning post 41 is firmly connected to the air outlet cover 2.

[0056] In one optional embodiment of the invention, reference is made to... Figure 7 As shown, the positioning post 41 includes a first positioning part 412 and a second positioning part 413, and the first positioning part 412 and the second positioning part 413 are shaped to form the mounting hole 411. One side of the first positioning part 412 and one side of the second positioning part 413 are rotatably connected, and the other side of the first positioning part 412 and the other side of the second positioning part 413 are fixedly connected by fasteners 5, so that the spring 42 is pressed and fixed in contact with the mounting hole 411.

[0057] In this embodiment of the invention, the positioning post 41 may include a first positioning part 412 and a second positioning part 413, wherein the second positioning part 413 may be integrally formed with the air outlet cover 2. The first positioning part 412 and the second positioning part 413 are shaped to fit together, thereby forming a mounting hole 411 for the spring 42 to be fitted. A rotating shaft may be fixed to one side of the first positioning part 412, and a bearing seat may be provided on one side of the second positioning part 413. The first positioning part 412 and the second positioning part 413 are rotatably connected through the rotating shaft and the bearing seat.

[0058] Threaded holes are simultaneously provided on the other side of the first positioning part 412 and the other side of the second positioning part 413 at corresponding assembly positions, so that the spring 42 can be fixed on the positioning post 41 by means of threaded connection between the fastener 5 and the threaded hole. The fastener 5 may include, but is not limited to, screws, bolts and other components. Those skilled in the art can select specific fasteners 5 according to actual design requirements, and no further limitations are made here.

[0059] Therefore, when assembling the spring 42, the first positioning part 412 can be rotated around the rotation axis. Then, the spring 42 is placed on the second positioning part 413, ensuring that one end of the spring 42 contacts the air outlet shroud 2 and the other end contacts the upper cover 1. Next, the first positioning part 412 is rotated around the rotation axis so that the other side of the first positioning part 412 contacts the other side of the second positioning part 413. At this point, the mounting hole 411 formed by the first positioning part 412 and the second positioning part 413 and the spring 42 form a pressure contact fixation. Then, the fastener 5 is passed through the threaded hole and tightened until the first positioning part 412 and the second positioning part 413 are securely connected.

[0060] In one optional embodiment of the invention, reference is made to... Figure 7 As shown, the cross-sectional shape of the first positioning part 412 and the cross-sectional shape of the second positioning part 413 are both semi-circular. Therefore, the shapes of the first positioning part 412 and the second positioning part 413 fit together to form a mounting hole 411 with a circular cross-sectional shape. Correspondingly, the spring 42 and the mounting hole 411 can also be an interference fit, thereby ensuring that the pressure between the spring 42 and the positioning post 41 is uniform throughout, which can further improve the structural strength required for the deformation of the spring 42.

[0061] In other embodiments, the cross-sectional shape of the first positioning part 412 can be less than half a circle, and the corresponding cross-sectional shape of the second positioning part 413 can be greater than half a circle. Thus, by matching the shapes of the first positioning part 412 and the second positioning part 413, a mounting hole 411 with a circular cross-sectional shape can be formed.

[0062] In one optional embodiment of the invention, reference is made to... Figure 1 and Figure 4 As shown, the air outlet shroud 2 may include an edge portion 21, multiple first support ribs 22, and multiple second support ribs 23. The edge portion 21 is clearance-fitted with the air outlet 11. The multiple first support ribs 22 and multiple second support ribs 23 are staggered within the edge portion 21 to form an air outlet grille.

[0063] In this embodiment of the invention, the edge portion 21 may have the same shape as the outer surface of the air outlet 11. The staggered arrangement can be understood as the first support rib 22 and the second support rib 23 being arranged at an angle. Those skilled in the art can determine the included angle between the first support rib 22 and the second support rib 23 according to actual design requirements, without further limitation here. For example, the included angle can be 30°, 60°, 90°, and 120°, etc. Multiple first support ribs 22 are arranged parallel to each other, and multiple second support ribs 23 are arranged parallel to each other. In some embodiments, the edge portion 21, the first support rib 22, and the second support rib 23 are an integral structure. This integral structure design facilitates the production of the air outlet hood 2, thereby improving the production efficiency of the air outlet hood 2. The two ends of the first support rib 22 extend to the edge portion 21, and the two ends of the second support rib 23 extend to the edge portion 21.

[0064] In one optional embodiment of the invention, reference is made to... Figure 3 As shown, the width of the air outlet grille is less than or equal to a preset width threshold.

[0065] In this embodiment of the invention, the width W of the air outlet grille is as follows: Figure 3 As indicated by the annotation, the preset width threshold can be understood as the upper limit width to prevent users from putting their hands inside the air vent 2. For example, the preset width threshold can be 7mm, 8mm, or 9mm, etc. Those skilled in the art can determine the corresponding preset width threshold based on practical experience, and no further limitations are made here. As a preferred embodiment, the width of all air vent grilles can be the preset width threshold, which facilitates the production of the air vent 2.

[0066] Furthermore, when the angle between the first support rib 22 and the second support rib 23 is 90° (which can also be understood as the air outlet grille being rectangular), the width of the air outlet grille is the side length in its width direction; when the angle between the first support rib 22 and the second support rib 23 is any angle other than 90° (which can also be understood as the air outlet grille being a parallelogram with an interior angle not equal to 90°), the width of the air outlet grille is the distance between the two side lengths in its width direction.

[0067] In one optional embodiment of the invention, reference is made to... Figure 8As shown, the rotating assembly 3 may include a first rotating rod 31 and a second rotating rod 32. One end of the first rotating rod 31 is rotatably connected to the end face of the upper cover 1 away from the connecting groove 12, and the other end of the first rotating rod 31 is rotatably connected to one end of the second rotating rod 32. The other end of the second rotating rod 32 is rotatably connected to the end face of the air outlet shroud 2 away from the spring 42. Thus, the air outlet shroud 2 can be rotatably connected to the upper cover 1 via the rotating assembly 3.

[0068] In some embodiments, a limiting seat can be provided on the end face of the upper cover 1 away from the connecting groove 12, and one end of the first rotating rod 31 is embedded in the limiting seat and rotatably connected to the limiting seat. The limiting seat is used to limit the assembly position of the air outlet hood 2, so that the air outlet hood 2 is flush with the connecting groove 12.

[0069] In other embodiments, a limiting block may be provided in the area where the upper cover 1 is flush with the connecting groove 12. The limiting block extends toward the air outlet 11. Thus, when the air outlet cover 2 is in the closed state, the limiting block and the air outlet cover 2 form a pressure contact to limit the assembly position of the air outlet cover 2, so that the air outlet cover 2 is flush with the connecting groove 12.

[0070] In one optional embodiment of the invention, to facilitate the flipping of the air outlet cover 2, a handle can be provided on the end face of the air outlet cover 2 away from the upper cover 1. The user can apply pulling force based on the handle to drive the air outlet cover 2 to flip away from the upper cover 1, thereby changing the air outlet cover 2 from a closed state to an open state. Therefore, when the air outlet cover 2 or the impeller 6 needs cleaning, the user can use the handle to flip open the air outlet cover 2 and clean the air outlet cover 2, the impeller 6, or the air guide channel, improving the ease of cleaning the humidifier.

[0071] In summary, this invention discloses a humidifier, which may include an upper cover 1, an air outlet cover 2, a rotating assembly 3, and a spring hinge assembly 4. The upper cover 1 is connected to the humidifier body, and the upper cover 1 has an air outlet 11 and a connecting groove 12, with the connecting groove 12 penetrating through the upper cover 1 towards the air outlet 11. The air outlet cover 2 is located within the air outlet 11, and the rotating assembly 3 is installed between the air outlet cover 2 and the upper cover 1 to form a rotatable connection between them. The spring hinge assembly 4 is located on the end face of the air outlet cover 2 away from the upper cover 1 and extends into the connecting groove 12. When the pulling force that drives the air outlet cover 2 to rotate away from the upper cover 1 is removed, the pressure force generated between the spring hinge assembly 4 and the connecting groove 12 causes the air outlet cover 2 to return to its original position. Therefore, when the air outlet cover 2 or the fan wheel 6 needs to be cleaned, the user can open the air outlet cover 2 and clean it, which greatly reduces the difficulty of cleaning the humidifier.
