[0036] A humidifier 100 according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0037] Reference Figures 1-3 As shown, the humidifier 100 according to an embodiment of the present invention may include: a body 10, an atomizing element 20, a liquid storage container 30, and a pressure regulating component 40.

[0038] Specifically, the body 10 has an atomizing chamber 101, an atomizing element 20 is disposed in the atomizing chamber 101, and the atomizing element 20 is used to atomize the liquid in the atomizing chamber 101.

[0039] The specific structure of the atomizing element 20 in this application is not limited. For example, the atomizing element 20 can be a microporous atomizing plate. Specifically, the atomizing element 20 includes a metal plate. A high-frequency AC voltage is provided by a power source to cause the metal plate to vibrate. The central region of the metal plate is the mist outlet region, which has tiny holes. The metal plate strikes the liquid in the atomizing chamber 101, causing water to spray out from the holes, thereby forming a jet-type water mist at the mist outlet 109, which is beneficial to improving the humidification range and humidification effect of the humidifier 100. Another example is that the atomizing element 20 can be an ultrasonic atomizer, etc., all of which are within the protection scope of this invention.

[0040] In addition, the atomizing chamber 101 has a liquid inlet 106 and a liquid return port 103, the body 10 also has a pressure regulating chamber 102, and the liquid storage container 30 has a liquid storage chamber 301. The liquid return port 103 of the atomizing chamber 101 is connected to the liquid storage chamber 301 through a liquid return channel 104. The liquid inlet 106 of the atomizing chamber 101 is connected to the pressure regulating chamber 102 through a first liquid inlet channel 107, and the pressure regulating chamber 102 is connected to the liquid storage chamber 301 through a second liquid inlet channel 108. The pressure regulating component 40 is used to regulate the pressure in the pressure regulating chamber 102 to drive the liquid in the liquid storage chamber 301 into the pressure regulating chamber 102, and also to drive the liquid in the pressure regulating chamber 102 into the atomizing chamber 101.

[0041] Specifically, the pressure regulating component 40 reduces the pressure in the pressure regulating chamber 102, allowing the liquid in the storage chamber 301 to enter the pressure regulating chamber 102 through the second inlet channel 108; the pressure regulating component 40 increases the pressure in the pressure regulating chamber 102, allowing the liquid in the storage chamber 301 to enter the atomizing chamber 101 through the first inlet channel 107. The atomizing chamber 101 can buffer the liquid to prevent excessive pressure from affecting the stability and atomization effect of the atomizing element 20; the liquid in the atomizing chamber 101 can be atomized by the atomizing element 20 to humidify the outside; liquid that is not atomized in time can flow back to the storage chamber 301 through the return channel 104 for reuse, and to prevent excessive pressure caused by excessive accumulation of liquid in the atomizing chamber 101.

[0042] In the embodiments of this application, the pressure of the pressure regulating chamber 102 is adjusted by the pressure regulating component 40 to drive the liquid into the atomizing chamber 101, eliminating the need for consumables such as filter cotton rods in related technologies, which helps to reduce the user's operating costs and eliminates the need for consumable replacement steps, thus improving the user experience.

[0043] Furthermore, the pressure regulating component 40 makes the pressure regulation chamber 102 more flexible and controllable, thereby making it easier to adjust and control the start and stop, speed, etc. of the liquid delivery into the atomizing chamber 101, and making the mist output control of the humidifier 100 more flexible and precise.

[0044] According to an embodiment of the present invention, the humidifier 100 drives the liquid in the liquid storage chamber 301 into the atomizing chamber 101 by setting a pressure regulating chamber 102 between the liquid storage chamber 301 and the atomizing chamber 101, and by adjusting the pressure of the pressure regulating chamber 102 through the pressure regulating component 40. The un-atomized liquid can flow back to the liquid storage chamber 301 through the return liquid channel 104. The entire working process is free of consumables, which reduces the operating cost of the humidifier 100. In addition, the mist output state of the humidifier 100 is more flexible and precise, which is beneficial to improving the user experience.

[0045] It should be noted that the specific structures of the first liquid inlet channel 107 and the second liquid inlet channel 108 can be flexibly set, as long as the requirements are met that the liquid in the liquid storage chamber 301 can enter the pressure regulating chamber 102 and the liquid in the pressure regulating chamber 102 can enter the atomizing chamber 101 during the pressure regulation process in the pressure regulating chamber 102.

[0046] For example, in some embodiments, when the pressure in the pressure regulating chamber 102 decreases, the flow area of ​​the first liquid inlet channel 107 is smaller than the flow area of ​​the second liquid inlet channel 108, so that the liquid in the storage chamber 301 can enter the pressure regulating chamber 102; when the pressure in the pressure regulating chamber 102 increases, the flow area of ​​the first liquid inlet channel 107 is larger than the flow area of ​​the second liquid inlet channel 108, so that the liquid in the pressure regulating chamber 102 can enter the atomizing chamber 101.

[0047] For example, in some embodiments, such as Figures 2-3 As shown, a first check valve 51 is provided between the first liquid inlet channel 107 and the pressure regulating chamber 102. The first check valve 51 is unidirectionally openable from the pressure regulating chamber 102 to the first liquid inlet channel 107. A second check valve 52 is provided between the second liquid inlet channel 108 and the pressure regulating chamber 102. The second check valve 52 is unidirectionally openable from the second liquid inlet channel 108 to the pressure regulating chamber 102.

[0048] Therefore, when the pressure in the pressure regulating chamber 102 decreases, only the liquid in the storage chamber 301 can enter the pressure regulating chamber 102 through the second inlet channel 108, while the liquid in the atomizing chamber 101 and the first inlet channel 107 will not flow back; when the pressure in the pressure regulating chamber 102 increases, the liquid in the pressure regulating chamber 102 can only enter the atomizing chamber 101 through the first inlet channel 107, and will not flow back to the storage chamber 301 through the second inlet channel 108. The pressure regulating component 40 and the pressure regulating chamber 102 work together to drive the liquid from the storage chamber 301 into the atomizing chamber 101 with higher efficiency and easier control.

[0049] Furthermore, the dual one-way valves work together to regulate the pressure within the pressure regulating chamber 102, allowing the relative positions of the liquid storage container 30, atomizing chamber 101, pressure regulating component 40, and various connecting channels to be unrestricted. For example, the liquid storage container 30 can be higher than, lower than, or flush with the atomizing chamber 101, all of which ensure that the liquid flows along a predetermined path without backflow. This allows for a more compact arrangement of the liquid storage container 30, atomizing chamber 101, pressure regulating component 40, and connecting channels, resulting in a more compact overall humidifier 100 and facilitating miniaturization. For instance, the humidifier 100 can be used as a car humidifier, desktop humidifier, etc., meeting the needs of applications in smaller spaces.

[0050] The one-way valve structures of the first one-way valve 51 and the second one-way valve 52 can be flexibly configured. For example, the one-way valve may include a spring, a sealing plug, etc. For instance, the one-way valve may include a sealing plug and a spring. The sealing plug is movably disposed in the liquid inlet channel, and the inner circumferential surface of the liquid inlet channel is provided with a sealing surface. The spring is used to apply a driving force to the sealing plug, causing the sealing plug to abut against the sealing surface to block the liquid inlet channel. Under the action of the pressure in the pressure regulating chamber 102, the spring can deform to separate the sealing plug from the sealing surface, and the liquid inlet channel is opened.

[0051] In this application, the specific structure of the pressure regulating component 40 can be flexibly configured. For example, in some embodiments, the pressure regulating component 40 may include a gas driving device such as an air pump, which can blow fluid (such as gas) into the pressure regulating chamber 102 to increase the pressure in the pressure regulating chamber 102, and the gas driving device can extract the fluid in the pressure regulating chamber 102 to reduce the pressure in the pressure regulating chamber 102.

[0052] In some embodiments of the present invention, such as Figure 2 and Figure 5 As shown, the pressure regulating assembly 40 includes: a pressure regulating seat 41, a piston 42, and a driving member 43.

[0053] The pressure regulating seat 41 has a pressure regulating pipe 411 communicating with the pressure regulating chamber 102, and the piston 42 is movably disposed within the pressure regulating pipe 411. A driving member 43 is connected to the piston 42 and is used to drive the piston 42 to reciprocate. Under the drive of the driving member 43, the piston 42 can move away from the pressure regulating chamber 102, increasing the volume of the pressure regulating pipe 411 directly communicating with the pressure regulating chamber 102, thereby reducing the pressure within the pressure regulating chamber 102; conversely, under the drive of the driving member 43, the piston 42 can move closer to the pressure regulating chamber 102, decreasing the volume of the pressure regulating pipe 411 directly communicating with the pressure regulating chamber 102, thereby increasing the pressure within the pressure regulating chamber 102.

[0054] Therefore, the pressure inside the pressure regulating chamber 102 can be adjusted by the reciprocating movement of the piston 42. Furthermore, because the piston 42 fits against the wall of the pressure regulating pipe 411, fluid leakage is prevented, ensuring the safety of other components within the humidifier 100 and improving the sensitivity of pressure regulation within the pressure regulating chamber 102. For example, the piston 42 may include a flexible surface (such as a rubber or silicone surface), and the flexible material makes a sealing contact with the inner wall of the pressure regulating pipe 411 to ensure a seal during the reciprocating movement of the piston 42.

[0055] It should be noted that the pressure regulating seat 41 and the cavity defining the pressure regulating chamber 102 can be an integral part or separate parts connected together, both of which are within the protection scope of this invention.

[0056] In some embodiments, such as Figure 2 and Figure 5As shown, the drive component 43 includes a drive motor, and the voltage regulating assembly 40 also includes a connecting rod 45. One end of the connecting rod 45 is rotatably connected to the output end of the drive motor, and the connection point is eccentrically positioned relative to the output end of the drive motor; in other words, the rotation axis of one end of the connecting rod 45 is offset from the rotation axis of the output end of the drive motor. The other end of the connecting rod 45 is rotatably connected to the piston 42.

[0057] Therefore, during the rotation of the output end of the drive motor, one end of the connecting rod 45 can be relative to the rotation axis of the output end of the drive motor (e.g., Figure 2 The axis of rotation extending horizontally as shown undergoes eccentric motion, causing the other end of connecting rod 45 to swing relative to one end of connecting rod 45. Under the limiting action of piston 42, the other end of connecting rod 45 reciprocates along pressure regulating pipe 411 (e.g., Figure 2 (as shown, moving up and down) to drive piston 42 to reciprocate along pressure regulating pipe 411.

[0058] The output structure of the drive motor is not restricted, for example... Figure 2 and Figure 5 As shown, the output end of the drive motor may include an output shaft 431 and an eccentric wheel 44 disposed on the output shaft 431. The eccentric wheel 44 can rotate synchronously under the drive of the output shaft 431. One end of the connecting rod 45 is rotatably connected to the edge of the eccentric wheel 44 to perform eccentric motion.

[0059] It is understood that in this application, the spaces such as the first liquid inlet channel 107, the second liquid inlet channel 108, the liquid return channel 104, the pressure regulating chamber 102, and the atomizing chamber 101 can be integrated into one component, or they can be located in multiple components and connected to achieve flow path connectivity. For example Figures 2-4 As shown, the body 10 includes an atomizing seat 13, which defines an atomizing chamber 101; a return liquid pipe has a partial return liquid channel 104 and is inserted into the atomizing seat 13; and an inlet liquid pipe has a partial first inlet liquid channel 107 and is inserted into the atomizing seat 13.

[0060] For example, in some embodiments, such as Figure 2 and Figures 6-7 As shown, the humidifier 100 includes a connecting pipe 60, which includes a pipe body portion 61 and an annular sleeve portion 62. The pipe body portion 61 defines at least a portion of a second liquid inlet channel 108. The annular sleeve portion 62 surrounds the pipe body portion 61, and the lower edge of the annular sleeve portion 62 is connected to the outer peripheral surface of the pipe body portion 61. At least a portion of a liquid return channel 104 is defined between the annular sleeve portion 62 and the pipe body portion 61. The annular sleeve portion 62 is provided with an outlet 105 of the liquid return channel 104.

[0061] Therefore, at least a portion of the return liquid channel 104 and at least a portion of the second inlet liquid channel 108 are integrated into the connecting pipe 60, that is, the channel that directly mates with the liquid storage container 30 is integrated into the connecting pipe 60, facilitating the entry of liquid into the liquid storage chamber 301. For example, the connecting pipe 60 can be directly inserted into the liquid storage container 30, so that the liquid in the liquid storage chamber 301 can enter the second inlet liquid channel 108, and the liquid in the atomizing chamber 101 can flow back to the liquid storage chamber 301, making the pipeline connection simpler. The pipe body 61 is used to define both the second inlet liquid channel 108 and the return liquid channel 104, which simplifies the structure of the connecting pipe 60.

[0062] In some embodiments, such as Figure 6 and Figure 7 As shown, the annular sleeve portion 62 is located at the upper part of the tube body portion 61, and the outlet 105 of the return liquid channel 104 is located at the lower edge of the annular sleeve portion 62. The annular sleeve portion 62's location at the upper part of the tube body portion 61 increases the distance between the return liquid channel 104 and the liquid stored in the storage chamber 301, preventing the stored liquid from clogging the outlet 105 of the return liquid channel 104 and causing excessive backflow pressure. Furthermore, the liquid returning from the outlet 105 of the return liquid channel 104 can flow downwards along the outer surface of the tube body portion 61, rather than dripping directly into the storage chamber 301 from a height, which helps reduce noise from liquid backflow.

[0063] In some embodiments of the present invention, such as Figure 2 As shown, the body 10 may include a housing 12. The lower part of the housing 12 is provided with a connector. The connector defines a portion of the return liquid channel 104 and a portion of the second inlet liquid channel 108. The connecting pipe 60 is inserted into the connector to achieve communication between the channel inside the connecting pipe 60 and the channel at the connector. For example, the pipe body 61 is inserted into the connector to achieve connection, and the annular sleeve 62 abuts against the edge of the connector to achieve sealing.

[0064] In some embodiments, continue to refer to Figure 2 As shown, the upper part of the body 10 is detachably connected to the liquid storage container 30 to open and close the top opening of the liquid storage chamber 301. The body 10 includes a housing 12, and components such as the atomizing element 20 and the pressure regulating component 40 can be housed inside the housing 12. This ensures that the installation structure of components such as the atomizing element 20 and the pressure regulating component 40 will not be interfered with during the disassembly of the body 10 and the liquid storage container 30, and the housing 12 can protect the internal components (such as the pressure regulating component 40) and reduce the risk of water ingress. Furthermore, by integrating all components into the housing 12, the overall structure of the humidifier 100 is made more compact, which is beneficial for miniaturizing the humidifier 100. For example, the humidifier 100 can be used as a car humidifier, a desktop humidifier, etc., to meet the needs of use in smaller spaces.

[0065] In embodiments including the connecting pipe 60, the connecting pipe 60 can extend into or out of the liquid storage chamber 301 through the top opening of the liquid storage chamber 301, making it easy to assemble and disassemble the liquid storage container 30.

[0066] In some specific embodiments, such as Figure 2 As shown, the atomizing component 20, the pressure regulating component 40, the atomizing chamber 101, the pressure regulating chamber 102, the liquid return channel 104, the first liquid inlet channel 107, and part of the second liquid inlet channel 108 are all integrated into the housing 12 of the body 10. The lower part of the housing 12 is inserted and matched with the upper part of the liquid storage container 30, making the overall structure of the humidifier 100 simple and compact, easy to disassemble and assemble, and convenient to move and use.

[0067] According to some embodiments of the present invention, there may be one or more atomizing elements 20. The atomizing chamber 101 may include multiple chambers 11, and there may be multiple atomizing elements 20, with each atomizing element 20 corresponding to one of the multiple chambers 11. Therefore, atomization can be achieved using multiple atomizing elements 20, which is beneficial for achieving a larger mist output and improving the humidification effect. Of course, the multiple atomizing elements 20 can operate simultaneously or individually, making the mist output adjustable.

[0068] In the above embodiments, the multiple chambers 11 can be connected in series or in parallel. For example... Figures 2-4 As shown, multiple chambers 11 are connected in series. One end of the chamber 11 has an inlet 106 on its wall and the other end of the chamber 11 has a return port 103 on its wall, which simplifies the connection between the inlet channel and the return channel 104.

[0069] In some embodiments, such as Figure 4 As shown, the side wall of the chamber 11 may be provided with a cable passage 110, and the power cord of the atomizing element 20 may be passed through the cable passage 110 and the cable passage 110 shall be sealed to prevent the leakage of liquid and water mist in the atomizing chamber 101.

[0070] In some embodiments, such as Figures 2-4 As shown, at least one of the liquid inlet 106 and the liquid return outlet 103 has a baffle 11 along its edge, and the baffle 11 protrudes from the bottom surface of the atomizing chamber 101. The baffle 11 can block the liquid in the atomizing chamber 101 to a certain extent, so that a certain amount of liquid can be accumulated in the atomizing chamber 101. This helps to prevent the humidifier 100 from being damaged by dry burning when there is a lack of water in the liquid storage chamber 301, thus improving the safety of use.

[0071] In some embodiments, such as Figures 2-4As shown, the extension direction of the outlet section of the first liquid inlet channel 107 is set at an angle to the mist outlet direction of the atomizing element 20, so as to buffer the liquid entering the atomizing chamber 101 and prevent the liquid entering the atomizing chamber 101 from directly impacting the atomizing element 20 and affecting the stability and atomization effect of the atomizing element 20.

[0072] Here, the angle setting can be mutually perpendicular, or it can refer to the extension direction of the outlet section of the first liquid inlet channel 107 forming a certain angle with the mist outlet direction, so that the liquid in the outlet section does not directly rush towards the atomizing element 20. For example Figure 2 and Figure 3 As shown, the mist outlet direction of the atomizing element 20 is vertical, and the extension direction of the outlet section of the first liquid inlet channel 107 is horizontal (including but not limited to the horizontal direction). The horizontal and vertical directions are perpendicular to each other, or the horizontal and vertical directions form a certain angle.

[0073] like Figure 3 As shown in some specific embodiments, the liquid inlet 106 is located on the upper side of the first liquid inlet channel 107. The wall of the outlet section of the first liquid inlet channel 107 includes an inclined surface connected to the liquid inlet 106. The inclined surface is inclined upward along the flow direction, which can guide the liquid in the first liquid inlet channel 107 to the liquid inlet 106, making the liquid flow smoother.

[0074] Other configurations and operations of the humidifier 100 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.

[0075] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
