Description

Technical Field

[0001] This utility model relates to the field of steam humidifier technology, and in particular to a rapid steam output structure for a steam humidifier. Background Technology

[0002] Heated steam humidifiers are widely used in homes, offices, and medical environments as a common device for improving indoor air humidity. However, most heated steam humidifiers on the market today have a common problem: when the device is first started, the steam output is relatively slow, making it difficult to meet users' needs for rapid humidification. This is mainly because the steam generated by the heating element cannot be effectively concentrated at the steam outlet when the heating element is first started, causing the steam to diffuse and condense inside the humidifier, resulting in low humidification efficiency.

[0003] Existing steam humidifiers typically employ a simple open structure, lacking effective guidance for steam flow. The steam rises directly from the water surface into the air without a dedicated collection structure, resulting in a significant initial steam diffusion effect. Furthermore, some humidifiers, while featuring simple steam channels, still suffer from a prolonged delay in producing steam after startup due to the lack of an effective steam collection mechanism.

[0004] Therefore, it is necessary to further improve and perfect the existing technology to overcome these shortcomings, and this utility model is made based on this situation. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a steam humidifier with a simple structure that can quickly produce steam.

[0006] This utility model is achieved through the following technical solution:

[0007] To solve the above-mentioned technical problems, this utility model provides a rapid steam output structure for a steam humidifier, including a body, a water cup inside the body, a heating zone on the bottom surface of the water cup, a heating component attached to the bottom surface of the heating zone, a cover on the top of the water cup, a steam outlet on the cover, a downwardly extending steam-gathering hood assembly at the steam outlet, the lower end of the steam-gathering hood assembly extending to and covering the heating zone, and a plurality of first air inlets on the side wall of the upper end of the steam-gathering hood assembly.

[0008] To further solve the technical problem to be solved by this utility model, the present utility model provides a rapid steam output structure for a steam humidifier, wherein the steam gathering hood assembly includes a pipe joint provided around the steam outlet and extending downward, and an external steam pipe provided on the pipe joint, a plurality of first air inlets are provided on the side wall of the pipe joint, and the lower end of the external steam pipe abuts against the periphery of the heating zone.

[0009] To further address the technical problems to be solved by this utility model, the present utility model provides a steam humidifier with a rapid steam output structure, wherein the steam outlet is further provided with a downwardly extending inner steam pipe, and the inner steam pipe is provided with an anti-tipping structure.

[0010] To further address the technical problems of this invention, the present invention provides a rapid steam output structure for a steam humidifier. The anti-tipping structure includes an annular sealing protrusion on the upper sidewall of the inner steam pipe, a limiting protrusion on the lower sidewall of the inner steam pipe, several second air inlets located on the sidewall of the inner steam pipe between the sealing protrusion and the limiting protrusion, and a sphere inside the inner steam pipe. When the steam humidifier is upright, the sphere is located at the limiting protrusion, allowing steam from the outer steam pipe to enter the steam outlet through the second air inlets. When the steam humidifier is tilted, the sphere moves to the sealing protrusion and seals against it, thereby blocking the inner steam pipe.

[0011] In order to further solve the technical problems to be solved by this utility model, the present utility model provides a steam humidifier with a rapid steam output structure in which the cover is detachably connected to the body.

[0012] In order to further solve the technical problems to be solved by this utility model, the present utility model provides a steam humidifier with a rapid steam output structure, wherein the external steam pipe is detachably connected to the pipe joint.

[0013] To further solve the technical problem to be solved by this utility model, the present utility model provides a rapid steam output structure for a steam humidifier, wherein the pipe joint sidewall is provided with a groove, the upper end of the outer steam pipe is sleeved on the pipe joint, and the inner sidewall of the outer steam pipe is provided with a protruding locking point that can cooperate with the corresponding groove.

[0014] To further address the technical problems to be solved by this utility model, the present utility model provides a rapid steam output structure for a steam humidifier, wherein the slot includes an axial slot and a circumferential slot, and the corresponding locking point is inserted axially from the circumferential slot, then rotated into the circumferential slot and locked in the circumferential slot, forming a rotation locking mechanism.

[0015] To further address the technical problems to be solved by this utility model, in the rapid steam output structure of the steam humidifier provided by this utility model, the lower end diameter of the outer steam pipe is larger than its upper end diameter.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Please see Figures 1 to 4 As shown, this utility model provides a rapid steam output structure for a steam humidifier. This structure can effectively solve the technical problem of slow steam output speed after traditional steam humidifiers are started, and significantly improve the working efficiency of the humidifier and the user experience.

[0026] As shown in the figure, the rapid steam output structure of this steam humidifier mainly includes a body 1, inside which is a water cup 2 for holding water. The bottom surface of the water cup 2 has a heating zone 21, which is the core area for steam generation. A heating component 11 is fitted to the bottom surface of the heating zone 21. The heating component 11 can be a resistance wire, PTC heating element, heating tube, heating plate, brazed heating plate, or other suitable heating element, capable of converting electrical energy into heat energy to heat the water in the water cup 2, thus generating steam.

[0027] A lid 3 is provided on the top of the water cup 2, and a steam outlet 31 is provided on the lid 3, through which steam is released from the humidifier. The lid 3 is detachably connected to the body 1, making it convenient for users to add water and clean and maintain the equipment. A steam concentrator assembly 4 is provided at the steam outlet 31, which is one of the core innovative parts of this utility model. The lower end of the steam concentrator assembly 4 extends to the heating zone 21 and covers the heating zone 21, forming a relatively closed steam channel, effectively guiding the steam generated in the heating zone 21 to the steam outlet 31.

[0028] However, the steam-concentrating hood assembly 4 is not completely sealed; several first air inlets 411 are provided on the upper side wall of the steam-concentrating hood assembly 4. The main function of these air inlets is to provide a channel for steam outside the steam-concentrating hood assembly 4 to enter the steam outlet 31. Specifically, after the steam humidifier has been running for a period of time, a large amount of steam is generated in the water cup 2. The steam inside the steam-concentrating hood assembly 4 can reach the steam outlet 31 along the steam-concentrating hood assembly 4, while the steam outside the steam-concentrating hood assembly 4 enters the steam-concentrating hood assembly 4 through the first air inlets 411.

[0029] This design effectively solves the problem of steam buildup in traditional steam humidifiers during continuous operation, and prevents safety hazards caused by excessive steam pressure inside the water cup 2.

[0030] The first air inlet 411 also serves to balance the internal and external pressures of the steam hood assembly 4, keeping the entire steam flow system in a relatively stable state and ensuring the continuity and stability of steam output. Furthermore, the first air inlet 411 helps improve steam quality because the portion of steam entering through these holes is at a lower temperature. This lower-temperature steam mixes with the internal high-temperature steam, which can, to some extent, regulate the temperature of the final output steam, reducing the risk of burns.

[0031] In practical applications, the number, size, and distribution of the first air inlets 411 can be adjusted according to specific needs to achieve optimal steam collection and pressure balance. Generally, the first air inlets 411 are evenly distributed in a ring on the sidewall of the pipe joint 41. Simultaneously, the arrangement of the first air inlets 411 is carefully designed (e.g., number, size, and distribution) to ensure that external steam can smoothly enter the steam-gathering hood assembly 4 without affecting the efficiency of the steam-gathering hood assembly 4 in collecting the initial steam generated in the heating zone 21.

[0032] like Figure 1-4 As shown, the steam-gathering hood assembly 4 specifically includes a pipe joint 41 located around the steam outlet 31 and extending downwards, and an external steam pipe 42 located on the pipe joint 41. The aforementioned first air inlet 411 is located on the side wall of the pipe joint 41, and the lower end of the external steam pipe 42 abuts against the periphery of the heating zone 21, forming a relatively enclosed steam collection space. This design ensures that the steam generated in the heating zone 21 can be collected to the maximum extent and guided to the steam outlet 31, greatly improving the steam utilization rate.

[0033] To improve equipment safety, this utility model also includes a downward-extending inner steam pipe 32 at the steam outlet 31, with an anti-tipping structure installed in the inner steam pipe 32. Figure 2-4 As shown, the anti-tipping structure includes an annular sealing protrusion 321 on the upper side wall of the inner steam pipe 32, a limiting protrusion 322 on the lower side wall of the inner steam pipe 32, a plurality of second air inlets 323 on the side wall of the inner steam pipe 32 and located between the sealing protrusion 321 and the limiting protrusion 322, and a sphere 33 inside the inner steam pipe 32.

[0034] The anti-tipping structure works as follows: When the steam humidifier is placed upright, the ball 33, due to gravity, is positioned at the limiting protrusion 322 at the bottom of the inner steam pipe 32. At this time, the steam in the outer steam pipe 42 can enter the inner steam pipe 32 through the second air inlet 323 and eventually be released from the steam outlet 31. When the steam humidifier tipes over or tilts severely, the ball 33 will roll along the inner wall of the inner steam pipe 32 and eventually reach the upper sealing protrusion 321 to seal and block the inner steam pipe 32, preventing hot water from flowing out of the steam outlet 31 and effectively avoiding scalding accidents.

[0035] This invention also takes into account the cleaning and maintenance needs of the equipment. As mentioned above, the cover 3 is detachably connected to the body 1 for easy addition of water and cleaning of the water cup 2. At the same time, the external steam pipe 42 is also detachably connected to the pipe connector 41, allowing the user to remove the external steam pipe 42 along with the cover 3 for easy removal for adding water or cleaning.

[0036] like Figure 1As shown, a preferred detachable connection structure between the cover 3 and the body 1 includes a mounting groove on the outer wall of the cover and a latch on the inner wall of the body 1, wherein the latch and the corresponding mounting groove engage with each other. Alternatively, the detachable connection structure between the cover 3 and the body 1 can also employ threaded connections, magnetic links, or other connection structures.

[0037] like Figure 2 As shown, the connection between the external steam pipe 42 and the pipe fitting 41 employs a rotary locking mechanism. Specifically, the pipe fitting 41 has a groove 412 on its side wall, the upper end of the external steam pipe 42 is fitted onto the pipe fitting 41, and the inner side wall of the external steam pipe 42 has a protruding locking point 421 that can cooperate with the corresponding groove 412. Further, the groove 412 includes an axial groove 4121 and a circumferential groove 4122. The corresponding locking point 421 is axially inserted into the axial groove 4121, then rotated into the circumferential groove 4122, and locked in the circumferential groove 4122, forming a stable rotary locking mechanism. This design ensures both the strength of the connection and facilitates user assembly and disassembly. In addition, the external steam pipe 42 and the pipe fitting 41 can also be connected using threaded connections, magnetic connections, or other connection structures.

[0038] To further improve steam collection efficiency, the external steam pipe 42 adopts a design where the lower diameter is larger than the upper diameter, presenting a trumpet-shaped structure. This design increases the steam collection area, enabling more efficient collection of steam generated in the heating zone 21, reducing steam loss within the water cup 2, and improving steam utilization.

[0039] Inside the cover 3, there is also a steam distribution chamber 34 connected to the steam outlet 31. The steam outlet 31 is located at the lower end of the steam distribution chamber 34, and several steam nozzles 341 are located at the upper end of the steam distribution chamber 34. This design allows the steam to be secondary distributed within the distribution chamber 34 and then evenly released into the air through multiple steam nozzles 341, thus improving the humidification effect.

[0040] The working process of this utility model is as follows:

[0041] 1. First, the user fills the water cup 2 with an appropriate amount of water, correctly connects the external steam pipe 42 to the pipe connector 41, and then installs the cover 3 onto the machine body 1.

[0042] 2. After the power is turned on, the heating component 11 starts to work, heating the water in the water cup 2 to a boiling state. Since the heating zone 21 is covered by the vapor-gathering hood component 4, forming a relatively closed space, most of the steam generated in the heating zone 21 is confined within the vapor-gathering hood component 4 and cannot diffuse outward.

[0043] 3. As the water temperature rises, the water begins to boil and generate steam. The steam accumulates inside the steam hood assembly 4 and flows upward under pressure, entering the inner steam pipe 32 through the second air inlet 323, and finally being released from the steam outlet 31.

[0044] 4. After heating for a period of time, a large amount of steam is generated in the water cup 2. The steam outside the steam hood assembly 4 will enter the steam hood assembly 4 through the first air inlet 411, further increasing the steam output speed and preventing excessive steam accumulation in the water cup 2.

[0045] 5. After steam enters the steam distribution chamber 34, it is evenly released into the air through multiple steam nozzles 341 to humidify the environment.

[0046] 6. If the humidifier is tilted or severely tilted, the ball 33 in the inner steam pipe 32 will move to the sealing protrusion 321 and seal against it, blocking the inner steam pipe 32 and preventing hot water from flowing out of the steam outlet 31, thus ensuring safe use.

[0047] Compared with traditional steam humidifiers, this invention has the following significant advantages:

[0048] 1. Rapid steam output: Through the design of the steam hood assembly 4, the steam generated in the heating zone 21 is effectively collected and guided to the steam outlet 31, which greatly shortens the time from heating start-up to steam output and improves humidification efficiency.

[0049] 2. Dual exhaust: The upper side wall of the steam hood assembly is provided with a first air inlet, which allows steam outside the steam hood assembly inside the water cup to enter. When a large amount of steam is generated inside the water cup, the steam inside the water cup can be quickly discharged to avoid steam accumulation.

[0050] 3. Safe and reliable: The anti-tipping structure in the inner steam pipe 32 can automatically block the steam channel when the humidifier is tilted, preventing hot water from flowing out and effectively ensuring the user's safety.

[0051] 4. Easy to clean and maintain: Both the cover 3 and the external steam pipe 42 are designed to be detachable, making it easy for users to add water and perform cleaning and maintenance, thus extending the service life of the equipment.

[0052] 5. Simple structure and moderate cost: Compared with humidifiers that use fan-assisted or ultrasonic technology, this utility model has a simple structure and low manufacturing cost, making it more suitable for large-scale production and widespread application.

[0053] By combining the above technical features, this utility model successfully solves the technical problem of slow steam output speed after traditional steam humidifiers are started, and achieves the effect of rapid steam output, while taking into account safety, ease of use and economy.
