Summary of the Utility Model

[0005] In view of the above problems, the embodiments of this application provide a humidifier, which can solve the problem that there is a gap between the humidifier main body and the humidifying filter element or the water tank, resulting in a decrease in the humidifying effect of the humidifier or affecting the appearance, thereby ensuring the close fit between the humidifier main body and the humidifying filter element and the water tank, improving the overall appearance of the humidifier while improving the humidifying effect.

[0006] To achieve the above object, the embodiments of this application provide the following technical solutions:

[0007] The embodiments of this application provide a humidifier, including: a water tank; a humidifying filter element; a humidifier main body, including a main body and an air inlet net, the main body is arranged on the water tank and connected to the water tank; the main body has an air duct communicated with the water tank, the air inlet net is arranged at one end of the air duct close to the humidifying filter element and movably connected to the main body, and the air inlet net is configured to move between a first position and a second position along the extending direction of the air duct under the action of a force, so that the air inlet net abuts and cooperates with the end face of the humidifying filter element.

[0008] In the humidifier provided in the embodiment of the present application, the air inlet net is movably set in the air duct of the main body so that the position of the air inlet net in the air duct can be adjusted under the action of force to adapt to humidification filter elements of different heights, so that the end faces of the air inlet net and the humidification filter element abut and cooperate with each other, thereby achieving a close fit between the end faces of the humidifier main body and the humidification filter element, which can avoid a gap between the humidifier main body and the humidification filter element or the water tank, thereby improving the appearance of the humidifier, and the water vapor generated by the humidification filter element for humidification can directly and efficiently enter the air duct through the air inlet net, reducing the leakage of water vapor to the outside of the humidifier, thereby improving the humidification efficiency and humidification quality of the humidifier.

[0009] In some embodiments, the humidifier further includes: a driving mechanism, the driving mechanism is connected to the air inlet network, and the driving mechanism is configured to drive the air inlet network in the air duct to move along an extension direction of the air duct between the first position and the second position.

[0010] With such an arrangement, the driving mechanism directly drives the air inlet network to adjust the position of the air inlet network according to the end surface position of the humidification filter element, thereby improving the compatibility of the humidifier host and the humidification filter element.

[0011] In some embodiments, the host body includes a shell and a fan assembly, the air duct is arranged on the shell, the fan assembly is arranged in the air duct and is arranged on the side of the air inlet net away from the humidification filter element, and the driving mechanism is arranged between the fan assembly and the air inlet net and connected to the air inlet net.

[0012] With such an arrangement, the driving mechanism is located between the fan assembly and the air inlet network. When the driving mechanism drives the air inlet network to adjust its position, it will not affect the operation of the fan assembly. In addition, the structural compactness of the humidifier can also be improved.

[0013] In some embodiments, the driving mechanism includes a telescopic member, which is connected between the fan assembly and the air inlet net, and the telescopic member is configured to telescope along the extension direction of the air duct under the action of force to drive the air inlet net to move between the first position and the second position.

[0014] With such arrangement, the telescopic member can drive the air inlet net to move by its own telescopic movement, and the structure of driving the air inlet net is simple and easy to implement.

[0015] In some embodiments, the telescopic member is a hydraulic telescopic rod.

[0016] With such arrangement, the hydraulic telescopic rod can ensure the abutment and cooperation between the end faces of the air inlet net and the humidification filter element, thereby improving the stable abutment between the air inlet net and the humidification filter element.

[0017] In some embodiments, the telescopic member is an elastic member, and the air inlet net is abutted and matched with the end surface of the humidification filter element under the elastic force of the elastic member itself.

[0018] With such arrangement, the elastic member uses its own elastic force to make the air inlet net abut against the end face of the humidification filter element. When the position of the air inlet net needs to be adjusted, it is only necessary to apply the elastic force of the elastic member to the air inlet net to drive the air inlet net to move, so as to adjust the position of the air inlet net according to the height of the humidification filter element.

[0019] In some embodiments, the end of the fan assembly facing the air inlet net has a first positioning portion, the end of the air inlet net facing the fan assembly has a second positioning portion, and both ends of the elastic member are respectively connected to the first positioning portion and the second positioning portion.

[0020] With such arrangement, the two ends of the elastic member are fixed in position by the first positioning portion and the second positioning portion, which can prevent the elastic member from being offset, thereby improving the working reliability of the elastic member.

[0021] In some embodiments, the first positioning portion is at least one of a first positioning groove and a first positioning protrusion; the second positioning portion is at least one of a second positioning groove and a second positioning protrusion.

[0022] With such arrangement, the positioning structure of the elastic member is simple, easy to implement and low in cost.

[0023] In some embodiments, the driving mechanism also includes a guide member, a first end of the guide member is connected to one of the fan assembly and the air inlet net, a second end of the guide member is slidably connected to the other of the fan assembly and the air inlet net, and the guide member is configured to guide the movement of the air inlet net in the air duct.

[0024] With such arrangement, when the air inlet net moves in the air duct, it can be guided by the guide member to improve the accuracy of the moving route of the air inlet net in the air duct and prevent the air inlet net from tilting during movement and causing jamming with the air duct.

[0025] In some embodiments, the first end of the guide member is connected to the fan assembly, the air inlet net has a through hole, the second end of the guide member is inserted into the through hole, and the end of the second end of the guide member has a limiting portion, and when the air inlet net moves to the second position, the limiting portion abuts against the end face of the air inlet net facing away from the fan assembly.

[0026] With such a setting, the second end of the guiding member is inserted through the through hole of the air inlet net, and the air inlet net can stably slide along the guiding member through the through hole. In addition, the air inlet net is restricted to move between the limiting portion and the fan assembly to limit the movement space of the air inlet net and prevent the air inlet net from interfering with other components inside the humidifier main body.

[0027] In some embodiments, the elastic member is sleeved on the guiding member.

[0028] With such a setting, the elastic member can elastically expand and contract along the guiding member. In this way, while the guiding member guides the movement of the air inlet net, it also guides the elastic expansion and contraction of the elastic member, thereby improving the accuracy of the movement route of the air inlet net when it moves. In addition, by sleeving the elastic member on the guiding member, the structural compactness of the driving mechanism is improved.

[0029] In some embodiments, the limiting portion is a limiting protrusion, and the cross-sectional dimension of the limiting protrusion is larger than the cross-sectional dimension of the guiding member.

[0030] With such a setting, the structure of the limiting portion is simple, easy to implement, and has a low cost.

[0031] In some embodiments, the fan assembly includes a motor bracket, and the first end of the guiding member is fixedly provided on the motor bracket.

[0032] With such a setting, the motor bracket is fixedly connected to the housing, and one end of the guiding member is fixedly connected to the motor bracket to facilitate fixing the position of the guiding member and stably guiding the air inlet net.

[0033] In some embodiments, there are at least two driving mechanisms, and the at least two driving mechanisms are arranged at intervals along the circumferential direction of the air inlet net.

[0034] With such a setting, the movement reliability and stability of the air inlet net during position adjustment can be improved, and the problem of skew jamming due to uneven force can be avoided.

[0055] In the related art, a humidifier includes a water tank, a humidifying filter element, and a humidifier main body. The humidifying filter element is disposed in the water tank, and the humidifier main body is disposed on the water tank. The humidifier main body is in cooperation with the top end face of the humidifying filter element and is connected to the water tank. The humidifying filter element can absorb the water in the water tank. Subsequently, the airflow generated by the humidifier main body drives the water vapor evaporated by the humidifying filter element into the humidifier main body and gushes out from the air outlet on the humidifier main body to achieve humidification of the air. However, in the related art, there are certain deviations in the heights of different humidifying filter elements, resulting in gaps when the top end face of the humidifying filter element is in cooperation with the humidifier main body; or, the top end face of the humidifying filter element is higher than the water tank, resulting in a gap between the humidifier main body and the water tank, reducing the humidifying effect of the humidifier and causing a problem of poor appearance of the humidifier.

[0056] To solve the above problems, the present application provides a humidifier. By movably disposing the air inlet grille in the air duct of the main body of the host, the position of the air inlet grille in the air duct can be adjusted under the action of a force, so that the air inlet grille is in abutting cooperation with the end face of the humidifying filter element, realizing a tight fit between the end face of the humidifier main body and the humidifying filter element, avoiding gaps between the humidifier main body and the humidifying filter element or the water tank, thereby improving the aesthetic appearance of the humidifier, and the water vapor for humidification generated by the humidifying filter element can directly and efficiently enter the air duct through the air inlet grille, reducing the leakage of water vapor to the outside of the humidifier, thereby improving the humidifying efficiency and humidifying quality of the humidifier.

[0057] In order to make the above objects, features, and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0058] Please refer to Figure 1As shown in the figure, an embodiment of the present application provides a humidifier 10, including: a water tank assembly and a humidifier main unit 300 disposed on the water tank assembly; the water tank assembly includes a water tank 100 and a humidifying filter element 200 located inside the water tank 100; wherein, the water tank 100 is used for the humidifying water of the humidifier 10, and the humidifying water contained in the water tank 100 can be pure water, or it can also be an aqueous solution with additives such as mixed spices, bactericides, and essential oils. The embodiments of the present application do not make specific limitations on this. Hereinafter, the liquid in the water tank 100 will be collectively referred to as water and will not be specifically described anymore.

[0059] Please refer to Figure 2 As shown in the figure, the humidifier main unit 300 includes a main body 310 and an air inlet net 320. The main body 310 is disposed on the water tank 100 and connected to the water tank 100; the main body 310 has an air duct 311 communicating with the water tank 100; the air inlet net 320 is disposed at one end of the air duct 311 close to the humidifying filter element 200. It can be understood that the air inlet net 320 has grids communicating the water tank 100 and the air duct 311, and the air inlet net 320 needs to be in contact with the upper end surface of the humidifying filter element 200.

[0060] In addition, please continue to refer to Figure 2 As shown in the figure, the main body 310 includes a housing 312, an air outlet net 314, and a fan assembly 313. The air duct 311 is disposed in the housing 312, the fan assembly 313 is disposed in the air duct 311, the air inlet net 320 is disposed at one end of the air duct 311 close to the water tank 100, the air outlet net 314 is disposed at the other end of the air duct 311, and the fan assembly 313 is disposed in the air duct 311 and located between the air inlet net 320 and the air outlet net 314. The fan assembly 313 is used to provide driving force for the gas in the air duct 311 to increase the flow intensity and flow velocity of the gas in the air duct 311.

[0061] Exemplarily, as Figure 2 shown in the figure, the fan assembly 313 includes a motor bracket 3131, a motor 3132, and a fan 3133. The motor bracket 3131 is disposed in the air duct 311 and fixedly connected to the housing 312. The motor 3132 is fixedly disposed on the motor bracket 3131, and the fan 3133 is connected to the output shaft of the motor 3132 to drive the fan 3133 to rotate through the motor 3132, thereby providing driving force for the air flow in the air duct 311.

[0062] In addition, an air inlet can be provided on the side wall of the water tank 100. The air inlet can be arranged at a position close to the top of the water tank 100, so as to ensure that the water tank 100 can have a certain water storage capacity. The humidifying filter element 200 is arranged in the water tank 100, and a device such as a water pump can be used to pump the humidifying water in the water tank 100 to the top of the humidifying filter element 200 and spray it towards the humidifying filter element 200 to soak the humidifying filter element 200. In this way, when the humidifier 10 is operating, the motor 3132 in the air duct 311 drives the fan 3133 to rotate to drive the air flow in the air duct 311, so that the air flow entering the water tank 100 through the air inlet passes through the humidifying filter element 200, so that the flowing air flow carries the water vapor on the humidifying filter element 200, enters the air duct 311 through the air inlet net 320, and finally is discharged from the air outlet net 314 through the air duct 311, thereby increasing the water molecule content of the indoor air to improve the humidity of the indoor air and achieving the purpose of humidifying the indoor air.

[0063] In order to ensure that the upper end surface of the humidifying filter element 200 and the air inlet net 320 are always in abutting fit, in the embodiment of the present application, please refer to Figure 3 and Figure 4 As shown, the air inlet net 320 is arranged in the air duct 311 and is movably connected to the main body 310 of the host, so that the position of the air inlet net 320 in the air duct 311 is adjustable under an external force. For example, the air inlet net 320 can move between a first position and a second position in the air duct 311 along the extending direction of the air duct 311, so as to facilitate adjusting the position of the air inlet net 320 in the air duct 311 according to the height of the humidifying filter element 200, so that the air inlet net 320 is always in abutting fit with the end surface of the humidifying filter element 200, thereby improving the humidifying effect when the humidifier 10 is humidifying, and at the same time, it can also ensure that there is no gap when the water tank 100 is connected to the housing 312 in the humidifier host 300, thereby improving the overall aesthetic appearance of the humidifier 10.

[0064] It can be understood that the first position and the second position refer to two extreme positions that the air inlet net 320 can reach when moving in the air duct 311, that is, the air inlet net 320 moves between the first position and the second position in the air duct 311. Among them, the first position that can be reached is, for example, the position farthest from the water tank 100, and the second position is, for example, the position closest to the water tank 100, and any position of the air inlet net 320 between the first position and the second position can be represented by a third position, for example.

[0065] In specific implementation, when the humidifier main body 300 is disposed on the water tank 100, if the height of the humidifying filter element 200 is relatively high, when the humidifier main body 300 is tightly connected to the water tank 100 and interference occurs between the humidifying filter element 200 and the air inlet net 320, the air inlet net 320 can move from the second position to the first position along the air duct 311 under the pushing action of, for example, the humidifying filter element 200 until the upper end surface of the humidifying filter element 200 and the air inlet net 320 do not interfere with each other and are in abutting cooperation; if the height of the humidifying filter element 200 is relatively small, when the humidifier main body 300 is tightly connected to the water tank 100, there is a gap between the humidifying filter element 200 and the air inlet net 320. At this time, the air inlet net 320 can move from the first position to the second position under an external acting force so that the end surface of the air inlet net 320 and the humidifying filter element 200 are in abutting cooperation. In this way, by adjusting the position of the air inlet net 320 in the air duct 311, the air inlet net 320 and the humidifying filter element 200 are in abutting cooperation to improve the humidifying effect when the humidifier 10 humidifies, and at the same time, it can also ensure that there is no gap when the water tank 100 is connected to the housing 312 in the humidifier main body 300, thereby improving the overall aesthetics of the appearance of the humidifier 10.

[0066] As Figure 4 As shown in, the air inlet net 320 and the upper end surface of the humidifying filter element 200 are in abutting cooperation at the third position, realizing the tight fit between the end surface of the humidifier main body 300 and the humidifying filter element 200. There is no gap between the humidifier main body 300, the humidifying filter element 200 and the water tank 100. In addition, the appearance of the humidifier 10 shows strong integrity, and the water vapor for humidifying generated by the humidifying filter element 200 can directly and efficiently enter the air duct 311 through the air inlet net 320, reducing the leakage of water vapor to the outside of the humidifier 10, thereby improving the humidifying efficiency and humidifying quality of the humidifier 10.

[0067] In some embodiments, the acting force received by the air inlet net 320 during position adjustment can be the pushing force or pulling force brought by electric drive. At this time, the air inlet net 320 is actively adjusted in position; or, the acting force can also be the pushing force from the humidifying filter element 200. At this time, the air inlet net 320 is in the second position in the natural state, and when the humidifier main body 300 is connected to the water tank 100, the air inlet net 320 receives the pushing force from the humidifying filter element 200 to realize passive position adjustment.

[0068] In some embodiments, the humidifier 10 further includes a driving mechanism 330. The driving mechanism 330 is connected to the air inlet net 320 to provide a driving force to the air inlet net 320 through the driving mechanism 330, so that the air inlet net 320 moves between the first position and the second position along the extending direction of the air duct 311 in the air duct 311.

[0069] In some embodiments, the driving mechanism 330 can be an electrically driven mechanism, a hydraulic driven mechanism, or a mechanical driven mechanism. The driving mechanism 330 can passively or actively drive the air inlet net 320 to move in the air duct 311. When the humidifier main body 300 is not connected to the water tank 100, the air inlet net 320 can be located at the first position, the second position, or a third position at any position between the first position and the second position. When the humidifier main body 300 is connected to the water tank 100, the driving mechanism 330 can adjust the relative position between the air inlet net 320 and the humidifying filter element 200. For example, after the humidifier main body 300 is connected to the water tank 100, if the height of the humidifying filter element 200 is small, that is, there is a gap between the air inlet net 320 and the humidifying filter element 200, the driving mechanism 330 can drive the air inlet net 320 to move towards the second position so that the air inlet net 320 and the humidifying filter element 200 are in abutting cooperation with each other; if the height of the humidifying filter element 200 is high and there is interference between the air inlet net 320 and the humidifying filter element 200, resulting in a gap between the main body 310 and the water tank 100 and unable to be tightly connected, the air inlet net 320 can be driven to move towards the first position under the pushing action of the humidifying filter element 200 or under the driving force of the driving mechanism 330. When there is no gap between the main body 310 and the water tank 100, the movement stops, and the air inlet net 320 and the humidifying filter element 200 are in abutting cooperation with each other.

[0070] In some embodiments, the driving mechanism 330 includes, but is not limited to, a hydraulic mechanism, an elastic mechanism, a spiral mechanism, etc., as long as it can drive the position of the air inlet net 320 to move in the air duct 311.

[0071] In some embodiments, the driving mechanism 330 is disposed between the fan assembly 313 and the air inlet net 320 and is connected to the air inlet net 320. In this way, the overall compactness of the structure of the humidifier 10 can be improved.

[0072] It can be understood that the driving mechanism 330 is located between the fan assembly 313 and the air inlet net 320, and at the same time, the driving mechanism 330 is directly connected to the air inlet net 320. Furthermore, when the driving mechanism 330 adjusts the position of the air inlet net 320, it will not affect the operation of the fan assembly 313. And after the water vapor enters the air duct 311 through the air inlet net 320, it can be effectively driven by the fan assembly 313 to flow, realizing effective humidification. And through the connection with the air inlet net 320, the driving mechanism 330 can also drive the air inlet net 320 to move between the first position and the second position. One end of the driving mechanism 330 is connected to the air inlet net 320, and the other end of the driving mechanism 330 can be connected to the housing 312 or the fan assembly 313; the driving structure can be located inside the air duct 311 or outside the housing 312.

[0073] In some embodiments, there are at least two driving mechanisms 330. The at least two driving mechanisms 330 are arranged at intervals along the circumferential direction of the air inlet net 320. Two or more driving mechanisms 330 can simultaneously adjust the position of the air inlet net 320, thereby improving the reliability of the movement of the air inlet net 320.

[0074] In addition, the form of arranging at intervals along the circumferential direction of the air inlet net 320 enables the air inlet net 320 to adapt to the end face of the humidifying filter element 200 with a certain inclination angle, and only the driving distance of each driving mechanism 330 for the air inlet net 320 needs to be adjusted.

[0075] Exemplarily, if the top end face of the humidifying filter element 200 is an inclined end face, there must be positions with a larger distance and positions with a smaller distance between the top end face of the humidifying filter element 200 and the air inlet net 320. By driving the air inlet net 320 to move towards or away from the humidifying filter element 200 by corresponding distances with different driving mechanisms 330, different positions between the air inlet net 320 and the humidifying filter element 200 can be closely attached, thereby further improving the humidifying quality.

[0076] In some embodiments, the driving mechanism 330 includes a telescopic member. The telescopic member is connected between the fan assembly 313 and the air inlet net 320. The telescopic member is configured to expand and contract along the extension direction of the air duct 311 under the action of a force, so as to drive the air inlet net 320 to move between a first position and a second position.

[0077] In the embodiments of the present application, the telescopic member can change its own length, and thus can drive the air inlet net 320 to move between a first position and a second position, realizing the adjustment of the distance between the air inlet net 320 and the humidifying filter element 200. The telescopic member can be a structure of a multi-stage telescopic rod or a structure such as a cylinder push rod. One end of the telescopic member is fixedly connected to the fan assembly 313 or the housing 312, and the other end is connected to the air inlet net 320. Further, when the length of the telescopic member changes, the air inlet net 320 will be driven to move. Since the telescopic direction of the telescopic member is the same as the extension direction of the air duct 311, the air inlet net 320 can realize stable movement along the extension direction of the air duct 311, ensuring the smooth abutment between the air inlet net 320 and the humidifying filter element 200.

[0078] In some embodiments, the telescopic member is a hydraulic telescopic rod, which can adjust its own telescopic length by adjusting the internal hydraulic pressure. At the same time, after the air inlet net 320 abuts against the humidifying filter element 200, the hydraulic telescopic rod can prevent the air inlet net 320 from shaking or moving away from the humidifying filter element 200, thereby ensuring that the air inlet net 320 stably abuts against the top end face of the humidifying filter element 200, ensuring the stable abutment between the air inlet net 320 and the humidifying filter element 200, and improving the stability of the operation of the humidifier 10. Among them, the hydraulic telescopic rod can be in the form of electric adjustment.

[0079] In other embodiments, as Figures 4 to 6 shown, the telescopic member is an elastic member 331, and the air inlet net 320 abuts and cooperates with the end face of the humidifying filter element 200 under the action of the self-elastic force of the elastic member 331.

[0080] In the embodiment of the present application, the elastic member 331 can be made of an elastic material. Specifically, the elastic member 331 can be an elastic rubber member or a spring. The elastic member 331 undergoes elastic deformation when subjected to an external force. One end of the elastic member 331 is fixedly connected to the fan assembly 313 or the housing 312, and the other end is connected to the air inlet net 320. When the humidifier main body 300 is not connected to the water tank 100, the elastic member 331 is not subjected to an external force and is therefore in a natural state. Exemplarily, at this time, the air inlet net 320 is in the second position. During the connection process between the humidifier main body 300 and the water tank 100, the air inlet net 320 will abut against the top end face of the humidifying filter element 200. Subsequently, as the humidifier main body 300 gradually approaches the water tank 100, the air inlet net 320 will be subjected to the pushing pressure of the humidifying filter element 200. At this time, the elastic member 331 is compressed, and then the length of the elastic member 331 will be shortened and enter the compressed state. At this time, the elastic member 331 will apply a pushing force towards the humidifying filter element 200 to the air inlet net 320, so that the air inlet net 320 is closely attached to the humidifying filter element 200.

[0081] In addition, the length of the elastic member 331 can be set according to the length of the humidifying filter element 200. Specifically, the length of the elastic member 331 in its natural state can be set such that the distance between the second position of the air inlet net 320 and the main body 310 of the host is always greater than the distance between the top end face of the humidifying filter element 200 of any specification and the main body 310 of the host. Furthermore, it can be ensured that when the humidifying filter element 200 of any length is installed in the water tank 100, the air inlet net 320 can receive the pushing force of the elastic member 331 when it abuts against the humidifying filter element 200, so that the air inlet net 320 closely fits on the end face of the humidifying filter element 200 after the position is changed. At the same time, after the humidifier main unit 300 is disassembled from the water tank 100, the elastic member 331 can also reset the position of the air inlet net 320 to adapt to the next mutual abutting and cooperation with the humidifying filter element 200.

[0082] In some embodiments, please refer to Figure 7 and Figure 8 As shown, one end of the fan assembly 313 facing the air inlet net 320 has a first positioning portion 3134; as Figure 9 shown, one end of the air inlet net 320 facing the fan assembly 313 has a second positioning portion 321, and two ends of the elastic member 331 are respectively connected to the first positioning portion 3134 and the second positioning portion 321 to position the elastic member 331 and prevent the position of the elastic member 331 from shifting and affecting the reliability when the air inlet net 320 moves.

[0083] In the embodiment of the present application, two ends of the elastic member 331 are respectively connected to the first positioning portion 3134 and the second positioning portion 321, and two ends of the elastic member 331 are respectively fixedly connected to the fan assembly 313 and the air inlet net 320. Furthermore, after the elastic member 331 enters the compressed state, the end connected to the air inlet net 320 will not move relative to the air inlet net 320, ensuring the continuous pushing force on the air inlet net 320 and making the position adjustment of the air inlet net 320 more stable. Among them, the elastic member 331 can be connected to the first positioning portion 3134 and the second positioning portion 321 by means of gluing, clamping, abutting, etc., and has a simple structure, is easy to implement, and has a low cost.

[0084] In some embodiments, the first positioning portion 3134 is at least one of a first positioning groove and a first positioning protrusion; the second positioning portion 321 is at least one of a second positioning groove and a second positioning protrusion. It can be understood that the first positioning portion 3134 can be one of a first positioning groove and a first positioning protrusion, or can also be a combination of the two. Exemplarily, a first positioning protrusion can be provided inside the first positioning groove so that one end of the elastic member 331 is limited by the first positioning groove and clamped and fixed by the first positioning protrusion. Correspondingly, the second positioning portion 321 can be one of a second positioning groove and a second positioning protrusion, or can also be a combination of the two.

[0085] Wherein, the first positioning groove and the second positioning groove can enable both ends of the elastic member 331 to be respectively embedded in the first positioning groove and the second positioning groove, while the first positioning protrusion and the second positioning protrusion can enable both ends of the elastic member 331 to be respectively sleeved or clamped on the first positioning protrusion and the second positioning protrusion, thereby realizing stable fixation of the ends of the elastic member 331.

[0086] Exemplarily, as Figure 8 shown, the first positioning portion 3134 is the first positioning groove, and the first positioning groove is recessed on the blower assembly 313. Specifically, the first positioning groove is provided on the motor bracket 3131; the second positioning portion 321 is the second positioning groove. As Figure 9 shown in, the second positioning groove is recessed on the air inlet net 320, so that both ends of the elastic member 331 are respectively embedded in the first positioning groove and the second positioning groove, preventing the elastic member 331 from shifting circumferentially during elastic expansion and contraction.

[0087] In some embodiments, please refer to Figure 4 and Figure 6 shown, the driving mechanism 330 further includes a guiding member 332. The first end of the guiding member 332 is connected to one of the blower assembly 313 and the air inlet net 320, and the second end of the guiding member 332 is slidably connected to the other of the blower assembly 313 and the air inlet net 320. The guiding member 332 is configured to guide the movement of the air inlet net 320 in the air duct 311.

[0088] In the embodiment of the present application, the extending direction of the guiding member 332 is the same as the extending direction of the air duct 311, that is, the same as the moving direction of the moving axis of the air inlet net 320. Exemplarily, the first end of the guiding member 332 can be fixedly connected to the blower assembly 313, and the second end is slidably connected to the air inlet net 320. At this time, the guiding member 332 can protrude a certain distance from the blower assembly 313 to meet the movement of the air inlet net 320 between the first position and the second position. When the second end of the guiding member 332 is slidably connected to the air inlet net 320, a sliding groove can be opened on the side wall of the air inlet net 320, and the second end of the guiding member 332 is clamped in the sliding groove and moves along the sliding groove to realize the guiding of the movement of the air inlet net 320. Alternatively, the first end of the guiding member 332 can also be fixedly connected to the air inlet net 320, and the second end is slidably connected to the blower assembly 313. The guiding member 332 enables the air inlet net 320 to be well guided during position adjustment, thereby preventing the air inlet net 320 from deviating in direction during movement and realizing stable abutting cooperation between the air inlet net 320 and the humidifying filter element 200. Among them, the number of the guiding members 332 can be one or multiple.

[0089] In some embodiments, as Figure 4 、Figure 6 and Figure 7 As shown, the first end of the guide member 332 is connected to the fan assembly 313. Specifically, the first end of the guide member 332 is fixedly connected to the motor bracket 3131, and the air inlet net 320 has a through hole 322, and the second end of the guide member 332 is passed through the through hole 322. In this way, when the air inlet net 320 moves in the air duct 311, the air inlet net 320 can be guided by the guide member 332 to prevent the air inlet net 320 from being deflected and stuck.

[0090] Exemplarily, the first end of the guide member 332 is fixedly connected to the fan assembly 313, and the air inlet net 320 is provided with a through hole 322 whose inner diameter is greater than or equal to the outer diameter of the guide member 332. The number of the through holes 322 is the same as the number of the guide members 332, and each guide member 332 corresponds to an independent through hole 322. When the air inlet net 320 moves, the guidance is achieved through the mutual cooperation between the through holes 322 and the guide members 332.

[0091] In some embodiments, Figure 4 and Figure 6 As shown, the guide member 332 is a guide rod with a circular, elliptical or other cross-sectional shape.

[0092] In addition, as 4, Figure 6 and Figure 7 As shown, the end of the second end of the guide member 332 has a limiting portion 3321. When the air inlet net 320 moves to the second position, the limiting portion 3321 abuts against the end surface of the air inlet net 320 that is away from the fan assembly 313 to limit the air inlet net 320 from moving between the limiting portion 3321 and the fan assembly 313.

[0093] like Figure 4 and Figure 6 As shown, the limiting portion 3321 can be set to a structure whose outer diameter is larger than the diameter of the through hole 322. For example, the limiting portion 3321 can be a portion of the second end of the guide member 332 whose outer diameter gradually increases from the first end to the second end. When the air inlet net 320 moves to the second position, the through hole 322 cannot pass through the limiting portion 3321. Then, the limiting portion 3321 can prevent the air inlet net 320 from continuing to move in a direction away from the host body 310, and prevent the air inlet net 320 from moving too far in a direction away from the fan assembly 313, thereby ensuring the humidification effect and the compactness of the structure.

[0094] In some embodiments, Figure 4 and Figure 6As shown, the elastic member 331 is sleeved on the guiding member 332. Exemplarily, the elastic member 331 can be arranged as a hollow structure, such as a hollow elastic rubber member or a spring, etc. The elastic member 331 in this form has a hollow inner cavity that is connected at both ends, enabling the elastic member 331 to be sleeved on the guiding member 332. One end of the elastic member 331 is connected to the fan assembly 313 or the housing 312, and the other end is connected to the air inlet grille 320. Furthermore, during the telescopic process of the elastic member 331 itself, it can also be guided by the guiding member 332 to prevent the problem of the elastic member 331 skewing during telescoping, thereby improving the reliability of the movement of the air inlet grille 320. Additionally, by sleeving the elastic member 331 on the guiding member 332, the compactness of the structure can be improved, and the space in the air duct 311 can be saved.

[0095] Among them, both the guiding member 332 and the elastic member 331 can be multiple. The multiple guiding members 332 are arranged at intervals in the circumferential direction of the air inlet grille 320, and the elastic member 331 is sleeved on the corresponding guiding member 332.

[0096] In some embodiments, as Figure 4 and Figure 6 shown, the limiting portion 3321 is a limiting protrusion, and the cross-sectional dimension of the limiting protrusion is larger than the cross-sectional dimension of the guiding member 332.

[0097] In the embodiments of the present application, the limiting protrusion protrudes from the side wall of the guiding member 332, and on the guiding member 332, the cross-sectional dimension at the position of the limiting protrusion is larger than the cross-sectional dimensions of other parts of the guiding member 332. Furthermore, the limiting protrusion can effectively prevent the position adjustment of the air inlet grille 320 from exceeding the limit, and the limiting protrusion can effectively limit the elastic member 331 on the guiding member 332 to prevent the elastic member 331 from slipping off the guiding member 332. In addition, the limiting protrusion can be arranged as an elastic structure, and the outer diameter of one end of the limiting protrusion close to the second end of the guiding member 332 is set to be smaller than the outer diameter of the other end, and the outer diameter between the two ends of the limiting protrusion changes uniformly. Then, when the second end of the guiding member 332 is installed with the air inlet grille 320, the end with a smaller outer diameter of the limiting protrusion first penetrates into the through hole 322, and the end with a larger outer diameter will undergo elastic deformation and be squeezed through the through hole 322. After the limiting protrusion completely penetrates the through hole 322, the squeezed end with a larger outer diameter returns to its original state. Furthermore, the end with a larger outer diameter of the limiting protrusion cannot penetrate the through hole 322 in the reverse direction, thus realizing the protection against the elastic member 331 slipping off the guiding member 332.

[0098] In some embodiments, as Figure 7As shown, the first end of the guide member 332 is fixedly provided on the motor bracket 3131, and the motor bracket 3131 is fixedly connected to the inner wall of the air duct 311. One end of the guide member 332 is fixedly connected to the motor bracket 3131, thereby realizing the fixed connection with the housing 312, thus realizing the fixation of its own position, and achieving stable guidance for the position adjustment of the air inlet net 320.

[0099] It can be seen that in the humidifier provided by the embodiment of the present application, by movably arranging the air inlet net in the air duct of the main body of the host, the position of the air inlet net in the air duct can be adjusted under the action of force, so that the end face of the air inlet net abuts against and cooperates with the end face of the humidifying filter element, realizing the close fit between the end face of the humidifier host and the end face of the humidifying filter element, avoiding gaps between the humidifier host and the humidifying filter element or the water tank, thereby improving the appearance beauty of the humidifier, and the water vapor for humidification generated by the humidifying filter element can directly and efficiently enter the air duct through the air inlet net, reducing the leakage of water vapor to the outside of the humidifier, thereby improving the humidification efficiency and quality of the humidifier.
