Description

Technical Field

[0001] This utility model relates to the field of humidifiers, and more specifically, to a humidifier with an openable and closable air outlet. Background Technology

[0002] Humidifiers, as household appliances that increase ambient humidity, are widely used in homes and offices. To achieve the function of releasing atomized water vapor into the environment, existing humidifiers typically require an air outlet and a corresponding air duct structure. However, many humidifiers lack effective opening and closing controls for their air outlets. When the water tank is disassembled, the air outlet is open, allowing dust, moisture, and other impurities in the air to easily enter the air duct and the humidifier's interior. Over time, this accumulation can affect the humidifier's normal operation and shorten its lifespan. Utility Model Content

[0003] In view of this, the present invention provides a humidifier with an openable and closable air outlet.

[0004] The objective of this utility model is achieved through the following technical solution: A humidifier with an openable and closable air outlet, comprising: The base is equipped with an atomizing chamber and an atomizing generator; A water tank is detachably installed on the base. The water tank is provided with an atomizing channel and a water storage tank. The atomizing channel and the water storage tank are respectively connected to the atomizing tank, and the atomizing channel is opposite to the atomizing generator. An extension block with an internal air duct is integrally formed with the base. The extension block has an air outlet that communicates with the air duct and the air outlet is connected to the atomizing channel. The air outlet opening and closing assembly includes a bracket detachably mounted on the base, a baffle elastically connected to the bracket and movably engaged on the extension block, and a pressure rod mounted on the water tank. The baffle is used to close the air outlet, and the pressure rod is used to press the baffle to open the air outlet.

[0005] In the above technical solution, by setting up an air outlet opening and closing component, when the water tank is installed on the base, the pressure rod on the water tank will squeeze the baffle that is elastically connected to the bracket, thereby automatically opening the air outlet so that the air outlet can smoothly send the atomized water vapor out from the atomization channel; when the water tank is removed, the baffle will automatically reset and close the air outlet under the elastic action, which can effectively prevent dust and other impurities from entering the air duct, ensure the cleanliness of the base, reduce the impact of water vapor on the electronic components inside the base, and is easy to operate without the need for manual operation of the air outlet opening and closing.

[0006] In addition, the extension block and the base are integrally molded, which reduces the number of parts, lowers the mold cost and assembly process in the production process, not only improves production efficiency, but also makes the structure of the entire humidifier more compact and stable, making it more convenient to assemble, reducing the assembly errors that may occur due to the assembly of multiple parts, and improving the overall quality of the product.

[0007] Optionally, in one possible implementation, the top of the baffle is provided with a pressing part and a limiting flange, the pressing rod can abut against the pressing part, and the limiting flange can abut against the inner top of the extension block.

[0008] In the above technical solution, the pressing part serves as a clearly defined force-bearing point, ensuring that the pressure rod on the water tank can accurately and stably contact the baffle and apply pressure. This avoids jamming, wear, or malfunction caused by an unclear force-bearing point, making the baffle opening action smoother and more reliable. Secondly, when the baffle resets under the action of elastic force, the limiting protrusion abuts against the inner top of the extension block, preventing the baffle from moving upwards further. This ensures that the baffle returns to the same preset closed position each time, thereby accurately covering the air outlet, ensuring the reliability and consistency of the seal, and effectively preventing water vapor leakage.

[0009] Optionally, in one possible implementation, the bottom of the baffle is provided with a guide post, the bracket is provided with a guide hole that cooperates with the guide post, an elastic element is provided in the guide hole, and the guide post is movably inserted into the guide hole and abuts against the elastic element.

[0010] In the above technical solution, the guide post and the guide hole form a precise sliding pair, providing a forced and unique vertical guide path for the up-and-down movement of the baffle. This ensures that the baffle will not sway laterally or tilt during opening and closing, and will always maintain precise alignment with the air outlet. Furthermore, the elastic element is built into the guide hole and acts directly on the guide post, providing the baffle with a continuous, uniform, and constant-direction elastic restoring force.

[0011] Optionally, in one possible implementation, the guide post, guide hole, and elastic element are provided in two or more sets.

[0012] In the above technical solution, the multi-point guide forms a stable and balanced structure, avoiding the risks of jamming, warping, or tilting that may occur during the movement of the baffle. Furthermore, the symmetrical distribution of multiple elastic elements provides the baffle with a balanced and uniform restoring force. This ensures that when the baffle is closed, its entire sealing surface can simultaneously and uniformly press against the edge of the air outlet.

[0013] Optionally, in one possible implementation, the extension block is provided with grooves on both sides of the air outlet, and the baffle is provided with several sliders on opposite sides, the sliders being slidably engaged in the corresponding grooves.

[0014] In the above technical solution, the groove and the slider cooperate to create a precise linear guide track for the movement of the baffle. During the process of the pressure rod squeezing the baffle to open the air outlet and the baffle resetting and closing the air outlet under the action of the elastic element, the slider can only slide in a straight line within the groove, effectively restricting the degree of freedom of the baffle in other directions, ensuring that the baffle always moves along the predetermined straight trajectory, and avoiding situations such as the baffle shifting, swaying or tilting.

[0015] Optionally, in one possible implementation, the bracket is provided with a through hole communicating with the air duct and an air inlet communicating with the outside. A fan is also installed on the bracket, with the air intake end and the air outlet end of the fan facing the air inlet and the through hole, respectively.

[0016] In the above technical solution, the fan and bracket are integrated into a single functional module, facilitating later maintenance and cleaning. The fan's outlet is directly aligned with the through-hole of the bracket, which is in turn tightly connected to the air duct within the extension block. This "direct connection" design effectively reduces the airflow path. Air is efficiently drawn in and blown out by the fan, enabling the generated water mist to be delivered more quickly and powerfully, thereby increasing the mist output and humidification distance.

[0017] Optionally, in one possible implementation, a dust cover is also installed at the air inlet.

[0018] In the above technical solution, the humidifier continuously draws in outside air during operation. This air often contains a large amount of dust, hair, pollen, and other tiny particulate impurities. The dust cover installed at the air inlet effectively intercepts these dust particles and impurities, preventing them from entering the humidifier with the airflow.

[0019] Optionally, in one possible implementation, the outer periphery of the pressure rod is provided with at least one reinforcing rib, which is connected to the water tank and the pressure rod respectively.

[0020] In the above technical solution, the pressure bar needs to withstand the reverse force from the baffle every time the water tank is installed. The reinforcing rib greatly enhances the section modulus at the connection between the pressure bar and the water tank, effectively dispersing and offsetting the bending stress caused by repeated action, thereby reducing the risk of the pressure bar breaking at the root.

[0021] Optionally, in one possible implementation, a noise reduction plate is further included, which is detachably installed on the water tank and located at the atomization channel. The noise reduction plate is provided with an atomization port and a plurality of return water ports located around the atomization port.

[0022] In the aforementioned technical solution, the water mist generated by the atomizer contains some larger water droplets, and some of the water mist will recondense into liquid droplets upon contact with the atomization channel wall. These droplets will then drip back into the atomization chamber due to gravity, thus generating noise. The noise reduction plate design can effectively prevent water droplets from falling directly into the atomization chamber, breaking up and buffering these droplets to reduce noise.

[0023] Optionally, in one possible implementation, a float switch is provided inside the atomizing chamber, the float switch being used to control the connection and disconnection between the water storage chamber and the atomizing chamber.

[0024] In the above technical solution, the float switch automatically turns the water supply on or off based on the water level in the atomizing chamber. When the water level in the atomizing chamber drops to a low level, the float sinks, automatically opening the valve to allow water from the storage tank to flow in and replenish the chamber; when the water level rises to a preset safe height, the float rises, automatically closing the valve and stopping the water supply. This ensures that the atomizing chamber always maintains a safe water level sufficient to cover the atomizer. Attached Figure Description

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0034] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0035] Please refer to Figures 1-3 This embodiment provides a humidifier with an openable and closable air outlet 32, including: a base 1, a water tank 2 detachably mounted on the base 1, an extension block 3 with an internal air duct 31, and an air outlet opening and closing assembly 4; the base 1 is provided with an atomizing chamber 11 and an atomizing generator 12; the water tank 2 is provided with an atomizing channel 21 and a water storage chamber 22, the atomizing channel 21 and the water storage chamber 22 are respectively connected to the atomizing chamber 11, and the atomizing channel 21 is opposite to the atomizing generator 12; the extension block 3 is integrally formed with the base 1, and the extension block 3 is provided with an air outlet 32 ​​connected to the air duct 31, the air outlet 32 ​​is connected to the atomizing channel 21; the air outlet opening and closing assembly 4 includes a bracket 41 detachably mounted on the base 1, a baffle 42 elastically connected to the bracket 41 and movably locked on the extension block 3, and a pressure rod 43 mounted on the water tank 2, the baffle 42 is used to close the air outlet 32, and the pressure rod 43 is used to squeeze the baffle 42 to open the air outlet 32. The base 1 also contains a circuit board and control panel for controlling the atomizer 12 and the air outlet of the air duct 31. The atomizer 12 is an ultrasonic atomizer, which atomizes liquid water through high-frequency vibration.

[0036] In this embodiment, by setting up an air outlet opening and closing component 4, when the water tank 2 is installed on the base 1, the pressure rod 43 on the water tank 2 will squeeze the baffle 42 that is elastically connected to the bracket 41, thereby automatically opening the air outlet 32, so that the air outlet 32 ​​can smoothly discharge air to send the atomized water vapor out from the atomization channel 21; when the water tank 2 is disassembled, the baffle 42 automatically resets and closes the air outlet 32 ​​under the elastic action, which can effectively prevent dust and other impurities from entering the air duct 31, ensure the cleanliness of the base 1, reduce the impact of water vapor on the electronic components inside the base 1, and is easy to operate without the need for manual operation of the opening and closing of the air outlet 32.

[0037] In addition, the extension block 3 is integrally formed with the base 1, and the extension block 3 itself is also an integral structure, which reduces the number of parts, reduces the mold cost and assembly process in the production process, not only improves production efficiency, but also makes the structure of the entire humidifier more compact and stable, making it more convenient to assemble, reducing the assembly errors that may occur due to the assembly of multiple parts, and improving the overall quality of the product.

[0038] It should be noted that the base 1 is equipped with a detachable bottom cover. When assembling the air vent opening and closing assembly 4, it needs to be assembled from the bottom of the base 1. First, install the baffle 42 on the extension block 3 from the bottom of the base 1, and then install it on the base 1 according to the position of the baffle 42, so that the bracket 41 can limit the baffle 42. The operation is simple and convenient.

[0039] Please refer to Figure 4 In this embodiment, the top of the baffle 42 is provided with a pressing part 421 and a limiting flange 422. The pressing rod 43 can abut against the pressing part 421, and the limiting flange 422 can abut against the inner top of the extension block 3. The air outlet 32 ​​is provided on the side of the extension block 3. The baffle 42 is vertically arranged, and the pressing part 421 is a protrusion perpendicular to the baffle 42. After the air outlet 32 ​​is closed, it is flush with the top surface of the extension block 3. Furthermore, the limiting flange 422 extends along the edges of the baffle 42 and the pressing part 421. After the air outlet 32 ​​is closed, it abuts against the inner top of the extension block 3, that is, the top of the air duct 31, to prevent the baffle 42 from disengaging from the extension block 3 after resetting.

[0040] The pressing part 421 serves as a clearly defined force-bearing point, ensuring that the pressure rod 43 on the water tank 2 can accurately and stably contact the baffle 42 and apply pressure. This avoids jamming, wear, or malfunction caused by an unclear force-bearing point, making the opening action of the baffle 42 smoother and more reliable. Secondly, when the baffle 42 resets under the action of elastic force, the limiting protrusion 422 abuts against the inner top of the extension block 3, preventing the baffle 42 from moving upward. This ensures that the baffle 42 returns to the same preset closed position each time, thereby accurately covering the air outlet 32, ensuring the reliability and consistency of the seal, and effectively preventing water vapor leakage.

[0041] Please refer to Figure 3 and Figure 4 In this embodiment, the bottom of the baffle 42 is provided with a guide post 423, and the bracket 41 is provided with a guide hole 411 that cooperates with the guide post 423. An elastic element 44 is provided in the guide hole 411. The guide post 423 is movably inserted into the guide hole 411 and abuts against the elastic element 44. The end of the guide post 423 away from the baffle 42 is a stepped shaft structure, and the elastic element 44 is a metal spring that can be snapped onto the stepped shaft. The guide post 423 and the guide hole 411 are clearance-fitted, which can reduce the shaking of the guide post 423 in the guide hole 411. Furthermore, a chamfer is provided at the opening of the guide hole 411. This chamfer is provided to facilitate the assembly and cooperation between the guide post 423 and the guide hole 411, and to facilitate quick positioning.

[0042] The guide post 423 and the guide hole 411 form a precise sliding pair, providing a forced and unique vertical guide path for the up-and-down movement of the baffle 42. This ensures that the baffle 42 will not swing laterally or tilt during opening and closing, and will always maintain precise alignment with the air outlet 32. This precise alignment allows the baffle 42 to achieve a uniform and complete seal with the edge of the air outlet 32 ​​when closed, effectively preventing leakage; and when open, it also ensures smooth airflow and improves mist output efficiency.

[0043] Furthermore, the elastic element 44 is embedded within the guide hole 411 and acts directly on the guide post 423, providing the baffle 42 with a continuous, uniform, and constant-direction elastic restoring force. When the water tank 2 is installed and the pressure rod 43 presses down on the baffle 42, the guide post 423 compresses the elastic element 44, storing energy. When the water tank 2 is removed and the pressure disappears, the energy stored in the elastic element 44 is released, pushing the guide post 423 and causing the baffle 42 to accurately return to the closed position, achieving automatic and reliable closure.

[0044] Furthermore, the entire elastic reset mechanism is highly integrated and modular. During assembly, the operator only needs to insert the guide post 423 directly into the corresponding guide hole 411 to complete the connection between the baffle 42 and the bracket 41 and the installation of the elastic reset mechanism.

[0045] It should be noted that in this embodiment, the guide posts 423, guide holes 411, and elastic elements 44 are arranged in two or more sets. This multi-point guidance forms a stable and balanced structure, avoiding the risk of jamming, warping, or tilting that may occur during the movement of the baffle 42. Furthermore, the symmetrical distribution of multiple elastic elements 44 provides a balanced and uniform restoring force for the baffle 42. This ensures that when the baffle 42 is closed, its entire sealing surface can simultaneously and uniformly press against the edge of the air outlet 32.

[0046] Please refer to Figure 1In this embodiment, the extension block 3 is provided with grooves 33 on both sides of the air outlet 32, and the baffle 42 is provided with several sliders 424 on both sides of the opposite side. The sliders 424 are slidably locked in the corresponding grooves 33.

[0047] The groove 33 and the slider 424 work together to create a precise linear guide track for the movement of the baffle 42. During the process of the pressure rod 43 pressing the baffle 42 to open the air outlet 32 ​​and the baffle 42 resetting and closing the air outlet 32 ​​under the action of the elastic element 44, the slider 424 can only slide in a straight line within the groove 33, effectively restricting the degree of freedom of the baffle 42 in other directions, ensuring that the baffle 42 always moves along the predetermined straight trajectory, and avoiding situations such as the baffle 42 deviating, wobbling or tilting.

[0048] Understandably, during final assembly, workers only need to align the sliders 424 on both sides of the baffle 42 with the grooves 33 inside the extension block 3, and then push it downwards along the grooves 33. This simultaneously completes the positioning and connection of the baffle 42 and the extension block 3, and automatically aligns it with the guide post 423 at the bottom. This design makes the assembly process intuitive, fast, and with a low error rate, further improving production efficiency.

[0049] Please refer to Figure 5 In this embodiment, the bracket 41 is provided with a through hole 412 communicating with the air duct 31 and an air inlet 413 communicating with the outside. A fan 6 is also installed on the bracket 41, with the air intake end and air outlet end of the fan 6 facing the air inlet 413 and the through hole 412, respectively. The air inlet 413 can be located on the side or bottom of the bracket 41. Since the bracket 41 is located inside the base, the base is provided with a matching opening at the position corresponding to the air inlet 413 to ensure that the air inlet 413 can communicate with the outside.

[0050] The fan 6 and bracket 41 are integrated into a single functional module, facilitating later maintenance and cleaning. When the user needs to clean the fan 6 impeller or the base air duct 31, they only need to remove the entire bracket 41 from the base 1, without the need for tools or disassembling complex wiring. The air outlet of the fan 6 is directly aligned with the through hole 412 of the bracket 41, which is in close contact with the air duct 31 within the extension block 3. This "direct connection" design effectively reduces the airflow path. Air is efficiently drawn in and blown out by the fan 6, enabling the generated water mist to be delivered more quickly and powerfully, thereby increasing the mist output and humidification distance.

[0051] In this embodiment, a dust cover 414 is also installed at the air inlet 413. The dust cover 414 is detachably installed at the air inlet 413 on the bracket 41. During operation, the humidifier continuously draws in outside air through the air inlet 413. This air often contains a large amount of dust, hair, pollen, and other tiny particulate impurities. The dust cover 414, installed at the air inlet 413, effectively intercepts these dust and impurities, preventing them from entering the humidifier with the airflow.

[0052] Please refer to Figure 3 In this embodiment, at least one reinforcing rib 431 is provided on the outer periphery of the pressure rod 43. The reinforcing rib 431 is triangular in structure and is connected to the water tank 2 and the pressure rod 43 respectively.

[0053] Each time the water tank 2 is installed, the pressure rod 43 needs to withstand the reverse force from the baffle 42. Over time, the root of the pressure rod 43, which connects to the shell of the water tank 2, is prone to fatigue fracture due to stress concentration. The reinforcing rib 431 greatly enhances the section modulus at the connection between the pressure rod 43 and the water tank 2, effectively dispersing and offsetting the repeated bending stress, thereby reducing the risk of the pressure rod 43 breaking at the root and significantly improving the durability of the parts.

[0054] Please refer to Figure 6 This embodiment also includes a noise reduction plate 5, which is detachably installed on the water tank 2 and located at the atomization channel 21. The noise reduction plate 5 is provided with an atomization port 51 and a plurality of water return ports 52 located on the outer periphery of the atomization port 51. The atomization port 51 is opposite to the atomization generator 12, so that the water mist generated by the atomization generator 12 can directly enter the atomization channel 21 from the atomization port 51.

[0055] The mist produced by the atomizer contains some larger water droplets, and some of the mist will recrystallize into liquid droplets upon contact with the walls of the atomization channel. These droplets will then drip back into the atomization chamber due to gravity, producing a "drip-drip" noise. The noise reduction plate design effectively prevents water droplets from falling directly into the atomization chamber, acting as a target for impact, breaking up and cushioning these droplets to reduce noise.

[0056] In this embodiment, a float switch is installed inside the atomizing chamber. The float switch is used to control the connection between the water storage chamber and the atomizing chamber. The float switch is a commonly used component in existing atomizers, and its specific structure will not be described in detail here.

[0057] The float switch automatically turns the water supply on or off based on the water level in the atomizing chamber. When the water level in the atomizing chamber drops to a low level, the float sinks, automatically opening the valve to allow water from the storage tank to flow in and replenish the chamber. When the water level rises to a preset safe height, the float rises, automatically closing the valve and stopping the water supply. This ensures that the atomizing chamber always maintains a safe water level sufficient to cover the atomizer.

[0058] In the description of this utility model, it should be understood that terms such as "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0059] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.
