Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of humidifier, specifically, relate to a humidifier. BACKGROUND

[0002] At present, in the related art, the humidifier can vibrate liquid water, and then generate water mist to improve the humidity of the surrounding environment. The humidifier is internally provided with a water pump assembly and a vibration piece. The liquid is driven into the humidifier by the water pump assembly, and then the liquid water is vibrated by the vibration piece. However, since the water pump assembly and the vibration piece are arranged in the humidifier, the internal structure of the humidifier is complex, the number of components is increased, and the production cost is increased. UTILITY MODEL CONTENTS

[0003] The utility model aims at least to solve one of the technical problems existing in the prior art or related art.

[0004] Therefore, the first aspect of the utility model provides a humidifier.

[0005] Therefore, the first aspect of the utility model provides a humidifier.

[0006] The humidifier provided by the application can store liquid in the liquid storage cavity, can stably supply liquid to the humidifier, can improve the humidification efficiency, and can improve the stability of the mist generated in the humidification process.

[0007] The atomizing pump is used to absorb liquid from the storage chamber and vibrate the liquid to generate water mist, thereby increasing ambient humidity. The atomizing pump includes a pump body assembly and a vibrating plate. The pump body assembly has a mounting cavity, an inlet channel, and an outlet channel to guide the liquid flow and stably supply water to the atomizing chamber. The inlet channel is connected to the storage chamber. The vibrating plate is located within the mounting cavity, dividing it into an inlet chamber and an atomizing chamber. The inlet chamber is located on the side of the vibrating plate closest to the inlet channel and is connected to the inlet channel. Liquid from the storage chamber can enter the inlet chamber through the inlet channel. The atomizing chamber is located on the side of the vibrating plate furthest from the inlet channel, which improves atomization efficiency and reduces the impact of liquid backflow on the liquid flow rate in the inlet channel. The atomizing chamber is connected to the inlet chamber via the outlet channel and is also connected to the mist outlet, allowing the atomized liquid to be quickly discharged from the humidifier, improving humidification efficiency.

[0008] When the atomizing pump is working, it draws liquid from the storage chamber into the inlet chamber through the inlet channel and delivers it to the atomizing chamber through the outlet channel. The liquid entering the atomizing chamber is atomized by the vibrating plates. The vibration of the plates within the mounting cavity transforms the liquid into tiny droplets, thus atomizing the liquid within the atomizing chamber and improving atomization efficiency. The atomized liquid is then discharged from the housing through the mist outlet, increasing ambient humidity and humidifying the surrounding environment.

[0009] When the atomizing pump is working, the vibrating plate vibrates up and down along the height of the humidifier. When the vibrating plate moves upward, the volume of the inlet chamber increases, resulting in a decrease in pressure within the inlet chamber. Since the storage chamber is connected to the storage chamber via the inlet channel, the liquid in the storage chamber enters the inlet chamber through the inlet channel under the pressure difference between the two chambers, thus driving the liquid and completing the pumping operation of the atomizing pump. When the vibrating plate vibrates downward, the volume of the inlet chamber decreases, increasing the pressure within it. Because the atomizing chamber is connected to the mist outlet, the pressure within the atomizing chamber remains constant, while the pressure within the inlet chamber increases, leading to a decrease in the volume of the inlet liquid. The pressure inside the inlet chamber is greater than that inside the atomizing chamber. Under the pressure difference between the inlet and atomizing chambers, liquid flows from the inlet chamber into the atomizing chamber through the outlet channel, supplying liquid to the atomizing chamber. Therefore, by installing a vibrating plate inside the atomizing pump, the pressure inside the inlet chamber can be changed as the plate vibrates up and down. This allows the vibrating plate to perform the water intake function of the atomizing pump and then atomize the liquid. The atomizing pump with a vibrating plate can be used to drive liquid into the atomizing chamber or to vibrate the liquid to form a water mist. This allows for an integrated design of the vibrating plate and the pump, reducing the internal volume of the humidifier. Furthermore, by utilizing the vibrating plate within the atomizing pump, the atomizing and pumping functions can be combined, enabling a multi-functional and modular design that reduces the number of internal components, lowers internal structural complexity, and reduces production costs.

[0010] Meanwhile, since the atomizing pump can handle both water pumping and liquid atomization, its inclusion can reduce the space occupied by other components within the humidifier, enabling a compact design that expands the humidifier's application scenarios and makes it easier for users to operate.

[0011] The atomizing pump also includes a seal arranged around the vibrating plate and connected to the pump body assembly. This seal improves the airtightness between the atomizing chamber and the inlet chamber. When the vibrating plate vibrates up and down, the seal prevents direct communication between the atomizing chamber and the inlet chamber, ensuring that the pressure in the inlet chamber changes with the vibration of the vibrating plate. This allows water to be drawn from the storage chamber into the inlet chamber and driven into the atomizing chamber, improving the stability of the liquid intake and enhancing the reliability of the atomizing pump. Furthermore, the seal isolates the atomizing chamber and the inlet chamber, preventing the liquid in the inlet chamber from affecting the atomization process in the atomizing chamber, thus improving atomization efficiency and stability.

[0012] Furthermore, the installation of seals can prevent liquid leakage, improve atomization efficiency, protect the vibrating plate, enhance equipment safety, and facilitate maintenance and replacement.

[0013] Specifically, because the atomizing pump can integrate the water pump and the vibrating plate into one unit, the humidifier can be modularly assembled, making it more convenient for users to maintain and clean. It also makes it easier for users to disassemble the atomizing pump to ensure the hygiene and performance of the humidifier.

[0014] In addition, the humidifier in the above-mentioned technical solution provided by this utility model may also have the following additional technical features:

[0015] In some technical solutions of this utility model, optionally, when the atomizing pump is working, the vibrating plate deforms, and the volume of the liquid inlet chamber changes, so as to draw the liquid in the storage chamber into the liquid inlet chamber through the liquid inlet channel, and deliver it to the atomizing chamber through the liquid outlet channel.

[0016] In this technical solution, when the atomizing pump is working, the vibrating plate deforms, and the volume of the inlet chamber changes. As the volume of the inlet chamber increases, the pressure inside the inlet chamber decreases, and a pressure difference exists between the pressure inside the storage chamber and the inlet chamber. Under the action of this pressure difference, the liquid enters the inlet chamber from the storage chamber through the inlet channel. As the volume of the inlet chamber decreases, the pressure inside the inlet chamber increases, and a pressure difference exists between the inlet chamber and the atomizing chamber. Under the action of this pressure difference, the liquid enters the atomizing chamber from the inlet chamber through the outlet channel, and thus the atomizing pump drives the liquid.

[0017] Specifically, the deformation of the vibrating plate can be caused by changes in the thickness of the vibrating plate itself, such as periodically thickening or thinning.

[0018] The deformation of the vibrating plate can also be caused by the periodic protrusions or depressions of the vibrating plate itself.

[0019] In some technical solutions of this utility model, optionally, when the atomizing pump is working, the vibrating plate vibrates, the sealing element deforms with the vibration of the vibrating plate, and the volume of the liquid inlet chamber changes, so as to draw the liquid in the storage chamber into the liquid inlet chamber through the liquid inlet channel and deliver it to the atomizing chamber through the liquid outlet channel.

[0020] In this technical solution, when the atomizing pump is working, the vibrating plate vibrates, the sealing element deforms with the vibration of the vibrating plate, and the volume of the inlet chamber changes. As the volume of the inlet chamber increases, the pressure inside the inlet chamber decreases, and a pressure difference exists between the pressure inside the storage chamber and the pressure inside the inlet chamber. Under the action of the pressure difference, the liquid enters the inlet chamber from the storage chamber through the inlet channel. As the volume of the inlet chamber decreases, the pressure inside the inlet chamber increases, and a pressure difference exists between the inlet chamber and the atomizing chamber. Under the action of the pressure difference, the liquid enters the atomizing chamber from the inlet chamber through the outlet channel, and then the atomizing pump drives the liquid.

[0021] Specifically, the vibration generated by the vibrating plate is that the vibrating plate itself moves up and down reciprocally along the height direction of the atomizing pump, and the sealing element is an elastic element that can deform with the movement of the vibrating plate.

[0022] Optionally, in some technical solutions of this utility model, the humidifier further includes a first one-way valve, which is disposed in the liquid inlet channel so that the liquid inlet channel can be unidirectionally opened from the end near the liquid storage chamber to the end near the liquid inlet chamber.

[0023] In this technical solution, the humidifier also includes a first one-way valve, which is located in the liquid inlet channel to allow unidirectional flow from the end near the storage chamber to the end near the liquid inlet chamber, preventing backflow of liquid in the liquid inlet chamber and improving liquid intake efficiency. When the vibrating plate moves upward, the pressure in the liquid inlet chamber decreases. By setting the first one-way valve, liquid in the storage chamber can enter the liquid inlet chamber unidirectionally through the liquid inlet channel, achieving unidirectional liquid drive. At the same time, when the vibrating plate moves downward, the first one-way valve can prevent liquid in the liquid inlet chamber from flowing back into the liquid inlet channel and the storage chamber. Therefore, with the cooperation of the first one-way valve, liquid can be driven unidirectionally from the liquid inlet chamber to the liquid outlet channel, realizing the water pumping function of the atomizing pump, improving liquid intake efficiency, and preventing liquid backflow.

[0024] Optionally, in some technical solutions of this utility model, the first one-way valve includes a first elastic diaphragm, which covers one end of the liquid inlet channel near the liquid inlet chamber. One end of the first elastic diaphragm is connected to the pump body assembly, and the other end of the first elastic diaphragm is a free end.

[0025] In this technical solution, the first one-way valve includes a first elastic diaphragm. The first elastic diaphragm covers one end of the inlet channel near the inlet chamber. One end of the first elastic diaphragm is connected to the pump body assembly, and the other end is a free end. When liquid flows into the inlet chamber from the storage chamber side along the inlet channel, the first elastic diaphragm deforms under the action of pressure difference, thereby opening the inlet channel to allow liquid to enter the inlet chamber through the inlet channel. When the liquid attempts to flow in the reverse direction, the first elastic diaphragm, under pressure, presses tightly against the channel opening on the side of the inlet channel near the inlet chamber, preventing backflow of liquid.

[0026] Specifically, the first check valve can be an elastic diaphragm, i.e., the first check valve is set as an elastic diaphragm. Alternatively, the first check valve can also be a small ball or a cone. When liquid flows into the inlet chamber from one side of the storage chamber along the inlet channel, the pressure pushes the ball towards the spring, opening the inlet channel. When the liquid flows in the opposite direction, the spring pushes the ball to press against the inlet channel near the inlet chamber side, closing the inlet channel.

[0027] Optionally, in some technical solutions of this utility model, the humidifier further includes a second one-way valve, which is disposed in the liquid outlet channel so that the liquid outlet channel can be unidirectionally opened from the end near the liquid inlet chamber to the end away from the liquid inlet chamber.

[0028] In this technical solution, the humidifier also includes a second one-way valve, which is located in the liquid outlet channel to allow unidirectional flow from the end near the liquid inlet chamber to the end away from the liquid inlet chamber. When the vibrating plate vibrates downwards, the volume of the liquid inlet chamber decreases, increasing the pressure within the liquid inlet chamber. The pressure in the liquid inlet chamber is greater than the pressure in the atomizing chamber. Under the pressure difference between the liquid inlet chamber and the atomizing chamber, liquid flows from the liquid inlet chamber along the liquid outlet channel through the second one-way valve into the atomizing chamber, thus supplying liquid to the atomizing chamber. The second one-way valve enables unidirectional flow of liquid. Simultaneously, when the pressure in the liquid inlet chamber decreases, the pressure difference between the atomizing chamber and the liquid inlet chamber prevents liquid from flowing back from the atomizing chamber into the liquid inlet chamber, improving the stability of the atomizing pump.

[0029] Optionally, in some technical solutions of this utility model, the second one-way valve includes a second elastic diaphragm, which covers the end of the liquid outlet channel away from the liquid inlet chamber. One end of the second elastic diaphragm is connected to the pump body assembly, and the other end of the second elastic diaphragm is a free end.

[0030] In this technical solution, the second one-way valve includes a second elastic diaphragm. The second elastic diaphragm covers the end of the liquid outlet channel away from the liquid inlet chamber. One end of the second elastic diaphragm is connected to the pump body assembly, and the other end is a free end. When liquid flows into the atomizing chamber from the liquid inlet chamber side along the liquid outlet channel, the second elastic diaphragm deforms under the action of pressure difference, thereby opening the liquid outlet channel to allow liquid to enter the atomizing chamber through the liquid outlet channel. When the liquid attempts to flow in the reverse direction, the second elastic diaphragm, under pressure, presses tightly against the channel opening on the side of the liquid outlet channel closest to the atomizing chamber, preventing liquid backflow.

[0031] Specifically, the second check valve can be an elastic diaphragm, i.e., the second check valve is set as a second elastic diaphragm. Alternatively, the second check valve can be a small ball or a cone. When liquid flows into the atomizing chamber from the inlet chamber side along the outlet channel, the pressure pushes the ball towards the spring, opening the outlet channel. When the liquid flows in the opposite direction, the spring pushes the ball to press against the outlet channel near the atomizing chamber side, closing the outlet channel.

[0032] Specifically, springs can be omitted, and unidirectional control of the inlet and outlet channels can be achieved by setting the size of a small ball or cone larger than the channel size of the inlet and outlet channels.

[0033] In some technical solutions of this utility model, optionally, in the vibration direction of the vibrating plate, one side surface of the vibrating plate is the first surface; the radial section of the liquid inlet channel is the second surface; the ratio of the area of ​​the second surface to the area of ​​the first surface is less than or equal to 0.01.

[0034] In this technical solution, in the vibration direction of the vibrating plate, one side surface of the vibrating plate is the first surface; the radial section of the liquid inlet channel is the second surface; the ratio of the area of ​​the second surface to the area of ​​the first surface is less than or equal to 0.01. By limiting the ratio between the areas of the first and second surfaces, the pumping efficiency can be improved, while also ensuring that the pressure change in the liquid inlet chamber caused by the vibration of the vibrating plate can support the driving of the liquid in the liquid inlet channel, thereby improving the stability of the liquid inlet of the atomizing pump.

[0035] Specifically, the ratio of the area of ​​the second surface to the area of ​​the first surface can be 0.01, 0.005, 0.003, 0.002, or 0.001.

[0036] Optionally, in some technical solutions of this utility model, the diameter of the liquid inlet channel is less than or equal to 3 mm.

[0037] In this technical solution, the diameter of the liquid inlet channel is less than or equal to 3 mm, which can improve the pumping efficiency of the liquid and enhance the stability of the liquid supply.

[0038] Specifically, the diameter of the liquid inlet channel can be 3 mm, 2.5 mm, 2 mm, 1.5 mm, or 1 mm.

[0039] In some technical solutions of this utility model, optionally, the pump body assembly includes a first pump body and a second pump body, the second pump body is connected to the first pump body, the vibrating plate is disposed between the first pump body and the second pump body, and the first pump body, the second pump body and the vibrating plate surround the inlet and outlet liquid chamber.

[0040] In this technical solution, the pump assembly includes a first pump body and a second pump body, with the second pump body connected to the first pump body. A vibrating plate is disposed between the first and second pump bodies, and the first pump body, the second pump body, and the vibrating plate enclose an inlet chamber. The coordinated operation of the first and second pump bodies, along with the rapid vibration of the vibrating plate, can more effectively drive the liquid flow, thereby delivering more liquid in the same amount of time and improving pumping efficiency. Furthermore, the tight integration of the first pump body, the second pump body, and the vibrating plate reduces the number of parts, making the entire pump assembly more compact and easier to install and maintain.

[0041] Optionally, in some technical solutions of this utility model, the second pump body and the vibrating plate form an atomizing chamber on the side away from the liquid inlet chamber, and the top of the atomizing chamber has an opening that communicates with the mist outlet.

[0042] In this technical solution, the second pump body and the vibrating plate form an atomizing chamber on the side away from the liquid inlet chamber. The top of the atomizing chamber has an opening that is connected to the mist outlet, thereby realizing the rapid flow of atomized liquid and improving humidification efficiency.

[0043] Optionally, in some technical solutions of this utility model, the second pump body is provided with a transition chamber, which is located on the side of the atomizing chamber and is connected to the inlet chamber through the liquid outlet channel.

[0044] In this technical solution, the second pump body is equipped with a transition chamber located to the side of the atomizing chamber. The transition chamber is connected to the inlet chamber via a liquid outlet channel. When the vibrating plate vibrates downwards, the volume of the atomizing chamber increases, the volume of the inlet chamber decreases, and the pressure in the inlet chamber increases. The pressure in the inlet chamber is greater than the pressure in the atomizing chamber. Under the action of the pressure difference between the inlet chamber and the atomizing chamber, the liquid will enter the atomizing chamber from the inlet chamber along the liquid outlet channel. Because the second pump body is equipped with a transition chamber located to the side of the atomizing chamber and connected to the inlet chamber via a liquid outlet channel, the liquid flowing into the atomizing chamber will first enter the transition chamber, accumulate in the transition chamber, and then enter the atomizing chamber, thus achieving a stable liquid supply to the atomizing chamber and improving atomization efficiency.

[0045] Optionally, in some technical solutions of this utility model, the second pump body is provided with an overflow groove, one end of which is connected to the atomizing chamber and the other end is connected to the transition chamber.

[0046] In this technical solution, the second pump body is equipped with an overflow groove, one end of which is connected to the atomizing chamber and the other end to the transition chamber. Liquid is pumped from the inlet chamber into the transition chamber by the atomizing pump. When the liquid volume in the transition chamber reaches a certain level, it flows into the atomizing chamber along the overflow groove, achieving a stable liquid supply to the atomizing chamber and improving atomization efficiency and stability. The overflow groove also allows for continuous liquid supply to the atomizing chamber.

Detailed Implementation

[0059] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0060] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0061] The following reference Figures 1 to 8 This invention describes a humidifier according to some embodiments of the present invention.

[0062] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the embodiment of this utility model, a humidifier 100 is provided. The humidifier 100 includes a housing 110 and an atomizing pump 120. The housing 110 is provided with a liquid storage chamber 112 and a mist outlet 114. The atomizing pump 120 includes a pump body assembly 122, a vibrating plate 124, and a sealing element 126. The pump body assembly 122 is provided with a mounting cavity 130, a liquid inlet channel 132, and a liquid outlet channel 134. The liquid inlet channel 132 communicates with the liquid storage chamber 112. The vibrating plate 124 is disposed in the mounting cavity 130, which can divide the mounting cavity 130 into a liquid inlet chamber 136 and an atomizing chamber 138. The liquid inlet chamber 136 is located on the side of the vibrating plate 124 near the liquid inlet channel 132, and the liquid inlet... The cavity 136 is connected to the liquid inlet channel 132. The atomizing cavity 138 is located on the side of the vibrating plate 124 away from the liquid inlet channel 132. The atomizing cavity 138 is connected to the liquid inlet cavity 136 through the liquid outlet channel 134 and is also connected to the mist outlet 114. The sealing member 126 is arranged around the vibrating plate 124 and is connected to the pump body assembly 122. When the atomizing pump 120 is working, it can draw the liquid in the storage cavity 112 into the liquid inlet cavity 136 through the liquid inlet channel 132 and deliver it to the atomizing cavity 138 through the liquid outlet channel 134. The liquid entering the atomizing cavity 138 can be atomized by the vibrating plate 124. The atomized liquid is discharged from the housing 110 through the mist outlet 114.

[0063] The present application provides a humidifier 100, which includes a housing 110 and an atomizing chamber 138. The housing 110 is provided with a liquid storage chamber 112 and a mist outlet 114. The liquid storage chamber 112 is used to store liquid, which can stably supply liquid to the humidifier 100, improve humidification efficiency and the stability of mist generation during humidification.

[0064] The atomizing pump 120 is used to generate water mist and increase ambient humidity. The atomizing pump 120 includes a pump body assembly 122 and a vibrating plate 124. The pump body assembly 122 is provided with an installation cavity 130, an inlet channel 132 and an outlet channel 134 to guide the liquid flow and stably supply water to the atomizing chamber 138. The inlet channel 132 is connected to the storage cavity 112. The vibrating plate 124 is disposed in the installation cavity 130 and can divide the installation cavity 130 into an inlet cavity 136 and an atomizing chamber 138. The inlet cavity 136 is located on the side of the vibrating plate 124 closer to the inlet channel 132 and is connected to the inlet channel 132. The liquid in the storage cavity 112 can enter the inlet cavity 136 through the inlet channel 132. The atomizing chamber 138 is located on the side of the vibrating plate 124 away from the inlet channel 132, which can improve atomization efficiency and reduce the impact of liquid backflow on the liquid flow rate of the inlet channel 132. The atomizing chamber 138 is connected to the liquid inlet chamber 136 through the liquid outlet channel 134, and the atomizing chamber 138 is connected to the mist outlet 114, so that the atomized liquid can be quickly discharged from the humidifier 100, thereby improving the humidification efficiency.

[0065] When the atomizing pump 120 is working, it draws liquid from the storage chamber 112 into the inlet chamber 136 through the inlet channel 132, and delivers it to the atomizing chamber 138 through the outlet channel 134. The liquid entering the atomizing chamber 138 is atomized by the vibrating plate 124. Through the vibration of the vibrating plate 124 within the mounting cavity 130, the liquid entering the inlet chamber 136 is converted into tiny droplets, thereby achieving atomization of the liquid in the atomizing chamber 138 and improving atomization efficiency. The atomized liquid is discharged from the housing 110 through the mist outlet 114, increasing the ambient humidity and achieving humidification of the surrounding environment.

[0066] When the atomizing pump 120 is working, the vibrating plate 124 vibrates up and down along the height direction of the humidifier 100. When the vibrating plate 124 moves upward, the volume of the liquid inlet chamber 136 increases, and the pressure in the liquid inlet chamber 136 decreases. Since the liquid storage chamber 112 is connected to the liquid storage chamber 112 through the liquid inlet channel 132, under the action of the pressure difference between the liquid storage chamber 112 and the liquid inlet chamber 136, the liquid in the liquid storage chamber 112 will enter the liquid inlet chamber 136 through the liquid inlet channel 132, thereby driving the liquid and completing the water pumping work of the atomizing pump 120. When the vibrating plate 124 vibrates downward, the volume of the liquid inlet chamber 136 decreases, and the pressure in the liquid inlet chamber 136 increases. Since the atomizing chamber 138 is connected to the mist outlet 114, the pressure in the atomizing chamber 138 remains unchanged, while the pressure in the liquid inlet chamber 136 increases. The pressure difference between the inlet chamber 136 and the atomizing chamber 138 causes the liquid to flow from the inlet chamber 136 into the atomizing chamber 138 via the outlet channel 134, thus supplying liquid to the atomizing chamber 138. Therefore, by installing a vibrating plate 124 inside the atomizing pump 120, the pressure inside the inlet chamber 136 can be changed when the vibrating plate 124 vibrates up and down. This allows the vibrating plate 124 to complete the water intake operation of the atomizing pump 120 and to atomize the liquid. The atomizing pump 120 with the vibrating plate 124 can be used to drive the liquid into the atomizing chamber 138 or to vibrate the liquid to form a water mist, thereby achieving an integrated design of the vibrating plate 124 and the pump, reducing the structural volume. Meanwhile, by utilizing the vibrating plate 124 inside the atomizing pump 120, the atomizing function and the water pumping function can be combined, realizing the multi-functional and modular design of the atomizing pump 120, thereby reducing the number of internal components of the humidifier 100, reducing the complexity of the internal structure, and reducing production costs.

[0067] Meanwhile, since the atomizing pump 120 can both pump water and atomize liquid, the space occupied by the components in the humidifier 100 can be reduced by setting the atomizing pump 120, so as to achieve a compact design of the humidifier 100, which can enrich the application scenarios of the humidifier 100 and make it easier for users to use.

[0068] The atomizing pump 120 also includes a seal 126, which is arranged around the vibrating plate 124 and connected to the pump body assembly 122. The seal 126 improves the airtightness between the atomizing chamber 138 and the liquid inlet chamber 136. When the vibrating plate 124 vibrates up and down, the seal 126 prevents direct communication between the atomizing chamber 138 and the liquid inlet chamber 136, ensuring that the pressure in the liquid inlet chamber 136 changes with the vibration of the vibrating plate 124. This allows water to be drawn from the storage chamber 112 into the liquid inlet chamber 136 and driven into the atomizing chamber 138, improving the stability of the liquid intake of the atomizing pump 120 and enhancing its reliability. Furthermore, the seal 126 isolates the atomizing chamber 138 and the liquid inlet chamber 136, preventing the liquid in the liquid inlet chamber 136 from affecting the atomization process in the atomizing chamber 138, thus improving atomization efficiency and stability.

[0069] Furthermore, the sealing element 126 can also prevent liquid leakage, improve atomization efficiency, protect the vibrating plate 124, enhance equipment safety, and facilitate maintenance and replacement.

[0070] Specifically, since the atomizing pump 120 can integrate the water pump and the vibrating plate 124, the humidifier 100 can be modularly assembled, which makes it more convenient for users to maintain and clean it. It also makes it easier for users to disassemble the atomizing pump 120 to ensure the hygiene and performance of the humidifier 100.

[0071] This embodiment provides a humidifier 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0072] When the atomizing pump 120 is working, the vibrating plate 124 deforms, and the volume of the liquid inlet chamber 136 changes, so that the liquid in the liquid storage chamber 112 is drawn into the liquid inlet chamber 136 through the liquid inlet channel 132 and delivered to the atomizing chamber 138 through the liquid outlet channel 134.

[0073] In this embodiment, when the atomizing pump 120 is working, the vibrating plate 124 deforms, and the volume of the liquid inlet chamber 136 changes. As the volume of the liquid inlet chamber 136 increases, the pressure inside the liquid inlet chamber 136 decreases, and a pressure difference exists between the pressure inside the liquid storage chamber 112 and the liquid inlet chamber 136. Under the action of the pressure difference, the liquid enters the liquid inlet chamber 136 from the liquid storage chamber 112 through the liquid inlet channel 132. As the volume of the liquid inlet chamber 136 decreases, the pressure inside the liquid inlet chamber 136 increases, and a pressure difference exists between the liquid inlet chamber 136 and the atomizing chamber 138. Under the action of the pressure difference, the liquid enters the atomizing chamber 138 from the liquid inlet chamber 136 through the liquid outlet channel 134, and then the liquid is driven by the atomizing pump 120.

[0074] Specifically, the deformation of the vibrating plate 124 can be caused by a change in the thickness of the vibrating plate 124 itself, such as periodically thickening or thinning.

[0075] The deformation of the vibrating plate 124 can also cause the vibrating plate 124 itself to periodically produce protrusions or depressions.

[0076] This embodiment provides a humidifier 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0077] When the atomizing pump 120 is working, the vibrating plate 124 vibrates, the sealing member 126 deforms with the vibration of the vibrating plate 124, and the volume of the liquid inlet chamber 136 changes so that the liquid in the liquid storage chamber 112 is drawn into the liquid inlet chamber 136 through the liquid inlet channel 132 and delivered to the atomizing chamber 138 through the liquid outlet channel 134.

[0078] In this embodiment, when the atomizing pump 120 is working, the vibrating plate 124 vibrates, and the sealing member 126 deforms with the vibration of the vibrating plate 124, causing the volume of the liquid inlet chamber 136 to change. As the volume of the liquid inlet chamber 136 increases, the pressure inside the liquid inlet chamber 136 decreases, and a pressure difference exists between the pressure inside the liquid storage chamber 112 and the pressure inside the liquid inlet chamber 136. Under the action of the pressure difference, the liquid enters the liquid inlet chamber 136 from the liquid storage chamber 112 through the liquid inlet channel 132. As the volume of the liquid inlet chamber 136 decreases, the pressure inside the liquid inlet chamber 136 increases, and a pressure difference exists between the liquid inlet chamber 136 and the atomizing chamber 138. Under the action of the pressure difference, the liquid enters the atomizing chamber 138 from the liquid inlet chamber 136 through the liquid outlet channel 134, thereby driving the liquid through the atomizing pump 120.

[0079] Specifically, the vibration generated by the vibrating plate 124 is that the vibrating plate 124 itself moves up and down reciprocally along the height direction of the atomizing pump 120, and the seal 126 is an elastic element that can deform with the movement of the vibrating plate 124.

[0080] This embodiment provides a humidifier 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0081] like Figure 5 and Figure 6 As shown, the humidifier 100 also includes a first one-way valve 140, which is disposed in the liquid inlet channel 132 so that the liquid inlet channel 132 can be unidirectionally opened from one end near the liquid storage chamber 112 to one end near the liquid inlet chamber 136.

[0082] In this embodiment, the humidifier 100 further includes a first one-way valve 140, which is disposed in the liquid inlet channel 132 so that the liquid inlet channel 132 can be unidirectionally opened from one end near the liquid storage chamber 112 to one end near the liquid inlet chamber 136, thereby preventing liquid backflow in the liquid inlet chamber 136 and improving the liquid inlet efficiency. When the vibrating plate 124 moves upward, the pressure in the inlet chamber 136 decreases. By setting the first one-way valve 140, the liquid in the storage chamber 112 can enter the inlet chamber 136 unidirectionally through the inlet channel 132, realizing unidirectional driving of the liquid. At the same time, when the vibrating plate 124 moves downward, since the first one-way valve 140 can prevent the liquid in the inlet chamber 136 from flowing back to the inlet channel 132 and the storage chamber 112, the liquid can be driven unidirectionally from the inlet chamber 136 to the outlet channel 134 with the cooperation of the first one-way valve 140, realizing the water pumping function of the atomizing pump 120, improving the liquid inlet efficiency, and avoiding liquid backflow.

[0083] This embodiment provides a humidifier 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0084] The first one-way valve 140 includes a first elastic diaphragm 142, which covers one end of the liquid inlet channel 132 near the liquid inlet chamber 136. One end of the first elastic diaphragm 142 is connected to the pump body assembly 122, and the other end of the first elastic diaphragm 142 is a free end.

[0085] In this embodiment, the first one-way valve 140 includes a first elastic diaphragm 142, which covers one end of the inlet channel 132 near the inlet chamber 136. One end of the first elastic diaphragm 142 is connected to the pump assembly 122, and the other end is a free end. When liquid flows from the storage chamber 112 into the inlet chamber 136 along the inlet channel 132, the first elastic diaphragm 142 deforms under the pressure difference, thereby opening the inlet channel 132 to allow liquid to enter the inlet chamber 136 through the inlet channel 132. When the liquid attempts to flow in the opposite direction, the first elastic diaphragm 142, under pressure, presses tightly against the opening of the inlet channel 132 near the inlet chamber 136, preventing backflow of liquid.

[0086] Specifically, the first check valve 140 can be an elastic diaphragm, i.e., the first check valve 140 can be configured as a first elastic diaphragm 142. Alternatively, the first check valve 140 can also be a small ball or a cone. When liquid flows from the storage chamber 112 into the inlet chamber 136 along the inlet channel 132, the pressure pushes the ball towards the spring, opening the inlet channel 132. When the liquid flows in the opposite direction, the spring pushes the ball to press against the inlet channel 132 near the inlet chamber 136, closing the inlet channel 132.

[0087] This embodiment provides a humidifier 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0088] The humidifier 100 also includes a second one-way valve 144, which is disposed in the liquid outlet channel 134 so that the liquid outlet channel 134 can be unidirectionally opened from the end near the liquid inlet chamber 136 to the end away from the liquid inlet chamber 136.

[0089] In this embodiment, the humidifier 100 further includes a second one-way valve 144, which is disposed in the liquid outlet channel 134 so that the liquid outlet channel 134 can be unidirectionally opened from the end near the liquid inlet chamber 136 to the end away from the liquid inlet chamber 136. When the vibrating plate 124 vibrates downward, the volume of the inlet chamber 136 decreases, increasing the pressure inside the inlet chamber 136. The pressure inside the inlet chamber 136 is greater than the pressure inside the atomizing chamber 138. Under the action of the pressure difference between the inlet chamber 136 and the atomizing chamber 138, the liquid will enter the atomizing chamber 138 from the inlet chamber 136 along the outlet channel 134 through the second one-way valve 144, thus supplying liquid to the atomizing chamber 138. By setting the second one-way valve 144, one-way flow of liquid can be achieved. At the same time, when the pressure inside the inlet chamber 136 decreases, under the action of the pressure difference between the atomizing chamber 138 and the inlet chamber 136, the second one-way valve 144 can prevent the liquid from flowing back from the atomizing chamber 138 into the inlet chamber 136, thereby improving the stability of the atomizing pump 120.

[0090] This embodiment provides a humidifier 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0091] The second one-way valve 144 includes a second elastic diaphragm 146, which covers the end of the liquid outlet channel 134 away from the liquid inlet chamber 136. One end of the second elastic diaphragm 146 is connected to the pump body assembly 122, and the other end of the second elastic diaphragm 146 is a free end.

[0092] In this embodiment, the second one-way valve 144 includes a second elastic diaphragm 146. The second elastic diaphragm 146 covers the end of the liquid outlet channel 134 away from the liquid inlet chamber 136. One end of the second elastic diaphragm 146 is connected to the pump body assembly 122, and the other end of the second elastic diaphragm 146 is a free end. When liquid flows from the liquid inlet chamber 136 into the atomizing chamber 138 along the liquid outlet channel 134, the second elastic diaphragm 146 deforms under the action of pressure difference, thereby opening the liquid outlet channel 134 to allow liquid to enter the atomizing chamber 138 through the liquid outlet channel 134. When the liquid attempts to flow in the opposite direction, the second elastic diaphragm 146, under pressure, presses against the opening of the liquid outlet channel 134 near the atomizing chamber 138, preventing liquid backflow.

[0093] Specifically, the second one-way valve 144 can be an elastic diaphragm, i.e., the second one-way valve 144 can be configured as a second elastic diaphragm 146. Alternatively, the second one-way valve 144 can also be a small ball or a cone. When liquid flows from the inlet chamber 136 into the atomizing chamber 138 along the outlet channel 134, the pressure pushes the ball towards the spring, opening the outlet channel 134. When the liquid flows in the opposite direction, the spring pushes the ball to press against the outlet channel 134 near the atomizing chamber 138, closing the outlet channel 134.

[0094] Specifically, springs can be omitted. By setting the size of a small ball or cone larger than the channel size of the liquid inlet channel 132 and the liquid outlet channel 134, unidirectional control of the liquid inlet channel 132 and the liquid outlet channel 134 can be achieved.

[0095] This embodiment provides a humidifier 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0096] In the vibration direction of the vibrating plate 124, one side surface of the vibrating plate 124 is the first surface 160; the radial section of the liquid inlet channel 132 is the second surface 162 (along...). Figure 8 The dashed line shown represents the cross-section of the liquid inlet channel 132, which is the second surface 162; the ratio of the area of ​​the second surface 162 to the area of ​​the first surface 160 is less than or equal to 0.01.

[0097] In this embodiment, in the vibration direction of the vibrating plate 124, one side surface of the vibrating plate 124 is a first surface 160; the radial cross-section of the liquid inlet channel 132 is a second surface 162; the ratio of the area of ​​the second surface 162 to the area of ​​the first surface 160 is less than or equal to 0.01. By limiting the ratio between the areas of the first surface 160 and the second surface 162, pumping efficiency can be improved, while also ensuring that the pressure change in the liquid inlet chamber 136 caused by the vibration of the vibrating plate 124 can support the driving of the liquid in the liquid inlet channel 132, thus improving the stability of the liquid intake of the atomizing pump 120. A relatively small vibration amplitude can drive the liquid in the liquid inlet channel 132 to be stably drawn into the liquid inlet chamber 136.

[0098] Specifically, the radial direction of the liquid inlet channel 132 is direction F3.

[0099] Specifically, the ratio of the area of ​​the second surface 162 to the area of ​​the first surface 160 can be 0.01, 0.005, 0.003, 0.002, or 0.001.

[0100] Specifically, such as Figure 7 As shown, the vibration directions of the vibrating plate 124 are direction F1 and direction F2, that is, the vibrating plate 124 can vibrate upward along direction F1 or downward along direction F2.

[0101] This embodiment provides a humidifier 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0102] The diameter of the liquid inlet channel 132 is less than or equal to 3 mm.

[0103] In this embodiment, the diameter of the liquid inlet channel 132 is less than or equal to 3 mm, which can improve the pumping efficiency of the liquid and improve the stability of the liquid supply.

[0104] like Figure 8 As shown, the diameter of the liquid inlet channel 132 is L1.

[0105] Specifically, the diameter L1 of the liquid inlet channel 132 can be 3 mm, 2.5 mm, 2 mm, 1.5 mm, or 1 mm.

[0106] This embodiment provides a humidifier 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0107] The pump body assembly 122 includes a first pump body 150 and a second pump body 152. The second pump body 152 is connected to the first pump body 150. A vibrating plate 124 is disposed between the first pump body 150 and the second pump body 152. The first pump body 150, the second pump body 152 and the vibrating plate 124 surround the inlet chamber 136.

[0108] In this embodiment, the pump assembly 122 includes a first pump body 150 and a second pump body 152, with the second pump body 152 connected to the first pump body 150. A vibrating plate 124 is disposed between the first pump body 150 and the second pump body 152, and the first pump body 150, the second pump body 152, and the vibrating plate 124 enclose an inlet chamber 136. The coordinated operation of the first pump body 150 and the second pump body 152, along with the rapid vibration of the vibrating plate 124, can more effectively drive the liquid flow, thereby delivering more liquid in the same amount of time and improving pumping efficiency. Furthermore, the tight integration of the first pump body 150, the second pump body 152, and the vibrating plate 124 reduces the number of components, making the entire pump assembly 122 more compact and easier to install and maintain.

[0109] This embodiment provides a humidifier 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0110] The second pump body 152 and the vibrating plate 124 form an atomizing chamber 138 on the side away from the liquid inlet chamber 136. The top of the atomizing chamber 138 has an opening 164, which is connected to the mist outlet 114.

[0111] In this embodiment, the second pump body 152 and the vibrating plate 124 form an atomizing chamber 138 on the side away from the liquid inlet chamber 136. The top of the atomizing chamber 138 has an opening 164, which is connected to the mist outlet 114, thereby realizing the rapid flow of atomized liquid and improving humidification efficiency.

[0112] This embodiment provides a humidifier 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0113] The second pump body 152 is provided with a transition chamber 154, which is located to the side of the atomizing chamber 138. The transition chamber 154 is connected to the inlet chamber 136 through the liquid outlet channel 134.

[0114] In this embodiment, the second pump body 152 is provided with a transition chamber 154, which is located to the side of the atomizing chamber 138. The transition chamber 154 is connected to the inlet chamber 136 through the liquid outlet channel 134. When the vibrating plate 124 vibrates downward, the volume of the atomizing chamber 138 increases, the volume of the liquid inlet chamber 136 decreases, and the pressure in the liquid inlet chamber 136 increases. The pressure in the liquid inlet chamber 136 is greater than the pressure in the atomizing chamber 138. Under the action of the pressure difference between the liquid inlet chamber 136 and the atomizing chamber 138, the liquid will enter the atomizing chamber 138 from the liquid inlet chamber 136 along the liquid outlet channel 134. Since the second pump body 152 is provided with a transition chamber 154, which is located on the side of the atomizing chamber 138 and is connected to the liquid inlet chamber 136 through the liquid outlet channel 134, the liquid flowing into the atomizing chamber 138 will first enter the transition chamber 154, accumulate in the transition chamber 154, and then enter the atomizing chamber 138, thereby achieving a stable liquid supply to the atomizing chamber 138 and improving the atomization efficiency.

[0115] This embodiment provides a humidifier 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0116] The second pump body 152 is provided with an overflow groove 156, one end of which is connected to the atomizing chamber 138 and the other end is connected to the transition chamber 154.

[0117] In this embodiment, the second pump body 152 is provided with an overflow groove 156, one end of which is connected to the atomizing chamber 138 and the other end is connected to the transition chamber 154. Liquid is pumped from the inlet chamber 136 into the transition chamber 154 by the atomizing pump 120. When the liquid volume in the transition chamber 154 reaches a certain level, it flows along the overflow groove 156 into the atomizing chamber 138, achieving a stable liquid supply to the atomizing chamber 138 and improving atomization efficiency and stability.
