Description

Technical Field

[0001] The invention belongs to the technical field of humidifiers and relates to a foldable portable humidifier. Background Art

[0002] The humidifier for ventilator is an important part of the ventilator. Its function is to heat and humidify the inhaled gas. Good heating and humidification can prevent and reduce secondary respiratory infections and stimulation to the cardiopulmonary system in patients with mechanical ventilation, and keep the alveoli moist. At the same time, it can also reduce the consumption of heat and respiratory water, making it difficult for sputum crusts to form in the airway, and can reduce the viscosity of secretions and promote expectoration.

[0003] Existing respiratory humidifiers are usually designed to be large and bulky and cannot be portable. Simply reducing the size of the humidifier will affect the water capacity of the humidifier and the effect of moisture mixing, thereby affecting the battery life and humidification effect.

[0004] like Figure 1-2 As shown, the prior art humidifier and ventilator (CN 110075407 A) for a ventilator is a technical solution that sets a foldable water chamber at the top, and uses gravity to make the liquid flow down to the water tank for heating to generate steam for humidification. Although this technical solution allows the water chamber to be folded, it also brings the following problems to the use of the humidifier:

[0005] 1. The area of ​​the heating surface is reduced and the humidification mixing chamber is reduced, which may lead to less steam or uneven humidification;

[0006] 2. The water chamber on top has different downstream speeds due to different water volumes, and the liquid in the water chamber is at room temperature. The addition of new liquid will affect the temperature of the heated liquid in the water tank. This dynamic flow replenishment method is very unfavorable for temperature control and affects the humidification effect.

[0007] Therefore, under the premise of ensuring the humidification effect, designing a humidifier that is easy to carry has become a difficult problem that needs to be solved urgently. Summary of the invention

[0008] The purpose of the present invention is to provide a foldable portable humidifier in view of the deficiencies of the prior art.

[0009] In order to achieve the above object, the present invention adopts the following technical solutions:

[0010] A foldable portable humidifier comprises a heating base and an upper cavity, wherein the upper cavity is provided with an air inlet and an air outlet, and the upper cavity has a first position state and a second position state;

[0011] When the upper cavity is in the first position, the upper cavity is sealed and connected to the heating base, the heating base and the upper cavity together form a cavity for containing a mixture of liquid and water vapor, the heating surface of the heating base is located at the bottom of the cavity, and the air inlet and the air outlet are connected to the cavity;

[0014] When the flexible side wall is stretched, the upper cavity is in a first position state, and when the flexible side wall is folded, the upper cavity is in a second position state.

[0015] Furthermore, the flexible side wall is a multi-layer telescopic structure or an inner folding structure or a soft segmented structure.

[0016] Furthermore, the flexible side wall is made of silicone.

[0017] Furthermore, the heating base comprises a heat conducting plate, an edge of the heat conducting plate is bent to form a mounting groove, a bottom edge of the flexible side wall is located in the mounting groove, and the mounting groove squeezes the flexible side wall to form a seal.

[0018] Furthermore, the shell of the heating base is provided with a sealing groove, a sealing rubber ring is provided in the sealing groove, the heat conducting plate is installed in the shell, and the installation groove is fixed in the sealing groove.

[0019] Furthermore, the flexible side wall is detachably connected to the end cover, and the top end of the flexible side wall elastically wraps around the bottom end of the end cover to fix it.

[0020] Furthermore, the heating base is provided with a concave cavity, the upper cavity body bulges upward to form a chamber inside, the inner diameter of the concave cavity is larger than the outer diameter of the chamber, and the upper cavity body is detachably connected to the heating base;

[0021] When the upper cavity is sealed and connected to the heating base so that the chamber and the concave cavity are connected to form a containing cavity, the upper cavity is in a first position state;

[0022] When the upper cavity is inverted in the concave cavity of the heating base, the upper cavity is in the second position state.

[0023] Furthermore, a sealing buckle is provided on the edge of the upper cavity, and a flange matching with the sealing port is provided on the edge of the heating base;

[0024] When the upper cavity is in the first position, the upper cavity is fixedly connected to the heating base through the cooperation of the sealing buckle and the flange.

[0028] Furthermore, a temperature sensor is provided in the heating base.

[0029] Furthermore, the heating base is provided with a waterproof interface, and the waterproof interface is electrically connected to the heating component and the temperature sensor.

[0050] Reference Figure 3-13 As shown, a foldable portable humidifier comprises a heating base 100 and an upper cavity, wherein the upper cavity is provided with an air inlet 210 and an air outlet 220, and the upper cavity has a first position state and a second position state;

[0051] When the upper cavity is in the first position, the upper cavity is sealed and connected to the heating base 100, and the heating base 100 and the upper cavity together form a cavity 300 for containing a mixture of liquid 800 and water vapor, the heating surface of the heating base 100 is located at the bottom of the cavity 300, and the air inlet 210 and the air outlet 220 are in communication with the cavity 300;

[0052] When the upper cavity is in the second position, the volume of the cavity 300 is reduced, so that the overall height of the humidifier is reduced.

[0053] The foldable portable humidifier combines the dual-state design of the heating base 100 and the upper cavity, aiming to solve the problem of large size and inconvenience in carrying of traditional humidifiers, and improve portability while ensuring the humidification effect. Its design concept revolves around humidification efficiency and convenience, and through the conversion of the first position state and the second position state of the upper cavity, flexible switching between heating and storage is achieved.

[0054] In the first position, the humidifier enters the working mode: the upper cavity is sealed and connected to the heating base 100 to form a closed cavity 300 for containing liquid 800 and generating humidified gas. The heating surface of the cavity 300 is located at the bottom. Through the uniform heating of the heating base 100, the liquid 800 in the cavity 300 is rapidly converted into water vapor. The generated humidified gas is fully mixed with the air flow through the air inlet 210 and the air outlet 220 provided on the upper cavity to achieve a stable and uniform humidification effect. Thanks to the bottom heating design, the water vapor generation in the cavity 300 is stable and uniform, avoiding the temperature control instability problem that may occur in the upper water chamber, and effectively improving the airway humidification quality.

[0055] When the upper cavity is switched to the second position, the humidifier enters the storage mode: the flexible structure or inverted design of the upper cavity reduces the volume of the cavity 300, and the overall height is significantly reduced, which is convenient for storage and portability. This design makes the humidifier suitable for scenes such as going out and traveling, while ensuring the humidification effect and battery life of the product. Compared with traditional humidifiers, this design improves the portability and ease of use of the device without affecting the humidification performance.

[0056] This design achieves an innovative application of a dual-state folding structure, ensuring stable humidification efficiency when in use and optimizing the volume when not in use, making it suitable for multiple scenarios. The humidifier has a compact structure, uniform heating, and is easy to carry, making it particularly suitable for mobile and space-constrained environments.

[0057] Reference Figure 3-8 As shown, in the first embodiment, the upper cavity includes a flexible side wall 410 and an end cover 420, the air inlet 210 and the air outlet 220 are arranged on the end cover 420, and the upper and lower sides of the flexible side wall 410 are sealed and connected to the heating base 100 and the end cover 420 respectively;

[0058] When the flexible side wall 410 is stretched, the upper cavity is in a first position state, and when the flexible side wall 410 is folded, the upper cavity is in a second position state.

[0059] The design concept of this implementation case is based on the flexible side wall 410 structure to achieve flexible conversion between the use and storage states of the humidifier, thereby improving portability and humidification efficiency. The upper cavity is composed of the flexible side wall 410 and the end cover 420, and the end cover 420 is provided with an air inlet 210 and an air outlet 220. The working state and volume of the upper cavity are controlled by the extension and folding of the flexible side wall 410.

[0060] In the first position, the flexible side wall 410 is extended to its full length, the upper cavity and the heating base 100 form a sealed working chamber 620, and the liquid 800 inside the cavity 300 is evenly heated by the bottom heating surface to generate stable water vapor. The water vapor and air are fully mixed with the air flow through the air inlet 210 and the air outlet 220, thereby providing a uniform humidification effect for the user. The structure of the flexible side wall 410 ensures that the temperature and humidity of the gas in the cavity 300 can be stably controlled, which is suitable for providing continuous humidification for a long time.

[0061] When the humidifier is switched to the second position, the flexible side wall 410 is folded, and the volume of the upper cavity is reduced to a minimum, so that the overall height of the humidifier is significantly reduced, and it is convenient to carry and store. This design effectively solves the problem of large volume and bulky structure of traditional humidifiers, so that the humidifier can be easily folded and stored when not in use, which is convenient for users to carry and use when traveling or in outdoor scenes.

[0062] In general, the advantage of this implementation case is that a good balance between portability and humidification efficiency is achieved through the foldable design of the flexible side wall 410. It has a simple structure and good sealing performance, can provide a stable humidification effect, and has convenient storage capacity, which is suitable for scenes with limited mobility and space.

[0063] In the first implementation example, the flexible side wall 410 is a multi-layer telescopic structure, an inner folding structure, or a soft segmented structure. Through the design of the flexible side wall 410 of the multi-layer telescopic structure, the inner folding structure, or the soft segmented structure, a humidifier structure that can be freely extended and easy to carry is provided. The design idea is to achieve efficient conversion between the working state and the storage state of the humidifier through the flexible flexible side wall 410, so that the device has portability while ensuring the humidification effect.

[0064] The multi-layer telescopic structure is to design the flexible side wall 410 as a telescopic multi-layer material, each layer of which can be overlapped and stretched or contracted in the longitudinal direction. Usually, materials with good elasticity, such as silicone or TPU thermoplastic polyurethane, are used to achieve smooth movement and close fit between the multi-layer structures.

[0065] The inner folding structure is designed with embedded folds or wrinkles on the flexible side wall 410, so that the side wall can be fully unfolded when in use, and folded inward along the preset folds when not in use, thereby achieving a compression effect. This structure is commonly found in folding cups or folding barrels, and can achieve a large compression ratio.

[0066] The soft segmented structure divides the flexible side wall 410 into multiple independent soft segments, which are connected by flexible connecting materials, so that the side wall can be freely compressed or expanded like a "folding accordion". Each segment forms a stable structure when expanded, and is compressed layer by layer when folded.

[0067] In the working state, the flexible side wall 410 can be fully unfolded to make the upper cavity reach the maximum volume, forming sufficient space in the cavity 300 for accommodating the liquid 800. The heating base 100 is located at the bottom of the cavity 300, and evenly heats the liquid 800 to a suitable temperature, thereby generating stable water vapor, which is fully mixed with the air flow through the air inlet 210 and the air outlet 220 on the end cover 420, providing users with a continuous and uniform humidification effect.

[0068] When not in use, the flexible side wall 410 can be folded or compressed by multi-layer telescopic, inward folding or soft segmentation, so that the volume of the upper cavity is greatly reduced, and the overall height and volume of the humidifier are significantly reduced, which is convenient for storage or carrying. This design ensures that the humidifier has high flexibility in different usage scenarios, especially suitable for carrying outside and using in small spaces.

[0069] In the first implementation example, the flexible side wall 410 is made of silicone. Silicone is used as the main material of the flexible side wall 410 to ensure the durability, sealing and safety of the humidifier during folding and unfolding. Silicone has excellent flexibility and durability, and can maintain stable shape and function even after multiple expansion and folding. In addition, silicone is resistant to high temperatures and is suitable for the heating environment of the humidifier, ensuring that the side wall will not be deformed or damaged in the heated state, thereby improving the humidification effect.

[0070] Silicone is selected as the material of the flexible side wall 410 to ensure the structural stability of the humidifier during high-frequency folding use through its excellent fatigue resistance and anti-aging performance. At the same time, the flexibility of silicone helps to achieve multi-layer telescopic, inner folding or soft segmented structural design, so that the humidifier can be flexibly switched between the use and storage states.

[0071] When the humidifier is in use, the silicone side wall can be fully stretched to form a stable cavity 300 to contain the liquid 800, and generate uniform water vapor under the action of the heating base 100. When the humidifier enters the storage state, the silicone side wall can be folded or compressed, greatly reducing the volume of the humidifier, making it easy to carry and store. The high elasticity of silicone makes it have strong shape recovery during the stretching and contraction process, which can effectively maintain the sealing effect.

[0072] In implementation case 1, the heating base 100 includes a heat conducting plate 500, the edge of which is bent to form a mounting groove 510, the bottom edge of the flexible side wall 410 is located in the mounting groove 510, and the mounting groove 510 squeezes the flexible side wall 410 to form a seal. A heat conducting plate 500 is arranged in the heating base 100, and the edge of the heat conducting plate 500 is formed into a mounting groove 510 by a bending design. This design not only optimizes the heating effect, but also realizes efficient sealing with the flexible side wall 410. The bottom edge of the flexible side wall 410 is embedded in the mounting groove 510 of the heat conducting plate 500, and the mounting groove 510 squeezes the bottom edge of the side wall to form a stable sealing structure. This structural design ensures the sealing and heating efficiency of the humidifier when it is working.

[0073] The bent mounting groove 510 on the edge of the heat conducting plate 500 is designed to achieve sealing with the flexible side wall 410 through precise physical connection, thereby preventing water vapor leakage during heating and improving the heating efficiency and safety of the humidifier. By utilizing the high thermal conductivity of the heat conducting plate 500, the heating base 100 can quickly transfer heat to the liquid 800 at the bottom of the cavity 300, thereby achieving uniform water vapor generation.

[0074] In use, the heat conducting plate 500 provides heat through the heating base 100, and evenly heats the surface of the heat conducting plate 500 and the liquid 800 near the mounting groove 510. The bottom of the flexible side wall 410 is embedded in the mounting groove 510, and is pressed by the mounting groove 510 to ensure that water vapor does not leak from the bottom. Under the action of this sealing structure, the heat generated by the heat conducting plate 500 is fully transferred to the liquid 800, and the generated water vapor is mixed with the air through the air inlet 210 and the air outlet 220 in the cavity 300 to achieve a humidification effect.

[0075] In implementation case 1, the shell of the heating base 100 is provided with a sealing groove, a sealing rubber ring is provided in the sealing groove, the heat conducting plate 500 is installed in the shell, and the mounting groove 510 is fixed in the sealing groove. The shell of the heating base 100 is designed with a sealing groove, and a sealing rubber ring is provided in the sealing groove. This design further improves the waterproof performance and safety of the humidifier. The heat conducting plate 500 is fixed in the sealing groove through the mounting groove 510. This structure not only ensures the stable installation of the heat conducting plate 500, but also effectively prevents water vapor leakage in the internal space of the heating base 100, and avoids the risk of burns caused by the exposure of the heat conducting plate 500.

[0076] During the installation process, the installation groove 510 of the heat conducting plate 500 is precisely connected with the sealing groove of the heating base 100, and waterproof protection is achieved through the sealing rubber ring. The sealing groove structure not only firmly fixes the heat conducting plate 500, but also provides a double sealing effect to ensure that water vapor does not enter the electronic component area inside the heating base 100. At the same time, the embedded installation of the heat conducting plate 500 effectively prevents it from being exposed, preventing users from touching the heat conducting plate 500 when operating or using the humidifier, preventing burns.

[0077] In the first implementation example, the flexible side wall 410 is detachably connected to the end cap 420, and the top of the flexible side wall 410 elastically wraps the bottom of the end cap 420 to fix it. This structural design not only facilitates the disassembly and assembly of the device, but also greatly improves the convenience of cleaning the inside of the humidifier. Through the fixing method achieved by elastic wrapping, the user can easily remove the end cap 420, thereby quickly accessing the inside of the humidifier, facilitating the cleaning and maintenance of the cavity 300 and maintaining the hygiene of the device.

[0078] The design aims to achieve a firm fixation of the flexible side wall 410 and the end cap 420 through an elastic wrap connection, while retaining its convenient detachability, so that the user can clean and maintain the inside of the humidifier conveniently. The elastic wrap structure can provide a firm fixation effect and has a certain degree of flexibility, so that the user can separate the end cap 420 from the flexible side wall 410 during cleaning or maintenance, thereby avoiding the problem that the traditional humidifier is difficult to clean.

[0079] In the installed state, the top material of the flexible side wall 410 is elastic and can wrap around the bottom end of the end cap 420, and is fixed by elastic tightening, so that the end cap 420 and the flexible side wall 410 form a sealed connection. When cleaning is needed, the user only needs to gently pull open the elastic part at the top of the flexible side wall 410 to remove the end cap 420 and thoroughly clean the inside of the cavity 300. After disassembly and cleaning, the user only needs to insert the bottom end of the end cap 420 into the top end of the flexible side wall 410, and the elastic material will automatically tighten to achieve re-fixation.

[0080] Reference Figure 9-13 As shown, in the second embodiment, the heating base 100 is provided with a concave cavity 610, the upper cavity body bulges upward to form a chamber 620 inside, the inner diameter of the concave cavity 610 is larger than the outer diameter of the chamber 620, and the upper cavity body is detachably connected to the heating base 100;

[0081] When the upper cavity is sealed and connected to the heating base 100 so that the chamber 620 and the concave cavity 610 are connected to form the containing cavity 300, the upper cavity is in the first position state;

[0082] When the upper cavity is inverted in the concave cavity 610 of the heating base 100 , the upper cavity is in the second position state.

[0083] The heating base 100 of the humidifier is provided with a concave cavity 610, which, in conjunction with the upwardly protruding structure of the upper cavity, provides an efficient switching method between use and storage, significantly improving the portability and ease of use of the humidifier. Specifically, the chamber 620 of the upper cavity is connected to the concave cavity 610 of the heating base 100 to form an independent cavity 300 structure, and the inner diameter of the concave cavity 610 is larger than the outer diameter of the chamber 620 of the upper cavity, so that the upper cavity can be firmly embedded in the heating base 100 and realize a detachable connection.

[0084] In the first position, the upper cavity is sealed and connected to the heating base 100, and the chamber 620 is connected to the concave cavity 610 to form a complete cavity 300 for containing liquid 800 and generating water vapor. The heating surface of the heating base 100 is located at the bottom of the cavity 300, and generates stable water vapor by uniformly heating the liquid 800, and mixes with the air through the air inlet 210 and the air outlet 220 of the upper cavity, providing a uniform humidification effect for the user. When the humidifier is not in use, the upper cavity can be inverted in the concave cavity 610 of the heating base 100, so that the overall height of the humidifier is greatly reduced, which is convenient for carrying and storage. This inverted design not only saves storage space, but also protects the equipment and avoids the risk of collision or damage during movement.

[0085] This design connects the upper cavity and the heating base 100 through the cavity 610, which realizes the efficient conversion of the humidifier between the use and storage states, ensures the sealing of the device and the stability of the humidification effect, and improves the portability and compactness of the device.

[0086] In the second embodiment, a sealing buckle 630 is provided on the edge of the upper cavity, and a flange 640 cooperating with the sealing port is provided on the edge of the heating base 100;

[0087] When the upper cavity is in the first position, the upper cavity is fixedly connected to the heating base 100 through the cooperation of the sealing buckle 630 and the flange 640. This structure ensures that the upper cavity can be firmly fixedly connected to the heating base 100 in the first position. Through the close cooperation of the sealing buckle 630 and the flange 640, not only the upper cavity and the heating base 100 are firmly connected, but also the sealing of the cavity 300 is enhanced, effectively preventing water vapor leakage and ensuring the stability of the humidification effect.

[0088] When the upper cavity is in the first position, the sealing buckle 630 is seamlessly combined with the flange 640 to form a tight closed structure, so that the upper cavity and the heating base 100 maintain a high degree of sealing in the working state. The design of the sealing buckle 630 provides a stable connection effect, preventing the upper cavity from loosening or shifting during use, and ensuring the reliability of the humidifier. This fixing method not only improves the safety and sealing of the humidifier, but also facilitates users to quickly switch between use and storage, while ensuring that the humidification function of the device is not affected by the outside world, which is suitable for multi-scenario use needs.

[0089] In the above implementation case, a partition 700 is provided between the air inlet and the air outlet. It is used to extend the path length of the airflow, thereby effectively improving the humidification effect. The design of the partition 700 forces the airflow entering the cavity to flow a longer distance in the water vapor mixing area, so that the airflow and the water vapor are fully contacted and mixed, ensuring that the airflow reaches the required humidity level before passing through the air outlet.

[0090] By increasing the length of the airflow path, the partition 700 design achieves a more uniform humidification effect, avoiding the problem of insufficient humidification caused by the airflow flowing directly from the air inlet to the air outlet. When the airflow flows in the cavity 300, it is in continuous contact with the water vapor and obtains sufficient humidification, which not only improves the humidification effect, but also ensures that the air inhaled by the user is more comfortable and moist. This design improves the humidification effect without affecting the portability of the device, providing users with a better user experience.

[0091] In the above implementation case, the heating base 100 includes components and a heat conducting plate 500;

[0092] The heat conducting plate 500 is located on the upper surface of the heating base 100 to form a heating surface, and the heating assembly 110 is in close contact with the bottom surface of the heat conducting plate 500. This structure ensures that heat can be efficiently and evenly transferred to the liquid 800 in the cavity 300, so that the liquid 800 evaporates quickly to generate water vapor, thereby improving the humidification efficiency.

[0093] The heat conducting plate 500, as the upper layer of the heating surface, fits tightly with the heating assembly 110 to ensure that heat is transferred without loss, ensuring that the liquid 800 in the cavity 300 can be heated to an ideal temperature in a short time, generating sufficient water vapor for humidifying the air flow. This tight fit not only improves the heating efficiency, but also ensures the stability of the heating surface temperature, helping to provide a continuous and uniform humidification effect.

[0094] By designing the heating assembly 110 and the heat conducting plate 500 as an integrated structure, heat can be effectively transferred to the heating surface, reducing heat loss and improving the overall performance of the humidifier. At the same time, the heating system is made more reliable and efficient during operation, meeting the user's demand for fast and stable humidification of the humidifier.

[0095] In the above implementation case, the heating base 100 is provided with a temperature sensor 120. The heating base 100 is equipped with a temperature sensor 120 to monitor the temperature of the heating surface and the liquid 800 in the cavity 300 in real time to ensure that the heating process of the humidifier is stable and safe. The temperature sensor 120 can accurately capture the temperature change under the heating state and feed the data back to the control system, so as to accurately adjust the heating power, maintain a constant temperature of the water vapor in the cavity 300, and ensure the stability of the humidification effect.

[0096] Through real-time monitoring, the temperature sensor 120 can reduce the heating power or suspend heating after the water temperature reaches the ideal level, preventing overheating or dry burning, extending the service life of the equipment and improving safety. This design not only ensures the adaptability of the humidifier in different environments, but also effectively avoids the poor humidification effect caused by too high or too low temperature, providing users with a more comfortable and stable humidification experience. The introduction of the temperature sensor 120 significantly improves the performance of the humidifier, making it more intelligent and safer.

[0097] In the above implementation case, the heating base 100 is provided with a waterproof interface 130, and the waterproof interface 130 is electrically connected to the heating component 110 and the temperature sensor 120. This waterproof interface 130 not only provides protection for the humidifier itself, but also brings convenience to its use with the ventilator. By connecting the humidifier to the ventilator, the ventilator can directly control the heating and temperature monitoring functions of the humidifier, thereby realizing centralized control.

[0098] This design effectively reduces the repeated configuration of the control unit inside the humidifier, simplifies the internal structure of the humidifier, reduces the overall size and weight of the device, and makes the humidifier more portable. The centralized control design also improves the operating efficiency of the system, allowing the ventilator to synchronously adjust the humidification intensity of the humidifier to ensure the stability and adaptability of the airflow humidity. The introduction of the waterproof interface 130 not only increases the safety of the humidifier, but also makes the device smaller and easier to operate through coordinated control with the ventilator, thereby improving the user experience.

[0099] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
