Description

Technical Field

[0001] This utility model relates to the field of air humidification, and in particular to a sterilizing humidifier with a water-blocking structure. Background Technology

[0002] In existing technologies, although ultrasonic humidifiers can achieve rapid humidification, directly vibrating untreated tap water can easily cause bacteria, viruses, or minerals in the water to spread with the water mist, posing health risks or causing "white powder" pollution. To solve this problem, high-temperature sterilization humidifiers have gradually been applied. They sterilize water by heating it and then atomizing it after cooling, thus combining sterilization and humidification functions.

[0003] Our earlier patent application (application number 2025212816175) proposed an easy-to-clean disinfection humidifier. It employs a detachable isolation cover structure to divide the open water tank on the base into a heating pool, a cooling pool, and an atomizing pool, forming a unidirectional water flow path. This ensures both effective sterilization and ease of cleaning and maintenance. In this design, the isolation cover, through its bottom-formed heating chamber, cooling chamber, and atomizing chamber, works in conjunction with the water tank to achieve functional zoning.

[0004] However, in practical applications, it has been found that when the isolation cover structure divides the working water tank into multiple functional pools, especially when some pools (such as heating pool and cooling pool, or heating pool and atomizing pool) are enclosed by the side wall of the isolation cover and the side wall of the water tank, due to the tolerance gap between the outer wall of the isolation cover and the side wall of the water tank, the water in the heating pool that has not been fully heated passes through the gap and flows directly around the water passage of the heating pool into the cooling pool or atomizing pool, affecting the overall sterilization effect. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a sterilizing humidifier with a water-blocking structure.

[0006] To achieve the above objectives, the present invention provides a sterilizing humidifier, comprising a base, a mist outlet channel, and one or more isolation covers. The base has a built-in circuit system, and its top surface is provided with an open water storage tank and a working water tank. The water storage tank is equipped with a water outlet control device for controlling the inflow of water into the water tank. The bottom structure of the one or more isolation covers is provided with downward-extending partition members for separating a heating pool, a cooling pool, and a misting pool. The one or more isolation covers are detachably mounted on the working water tank with their bottom openings facing downwards. The working water tank is divided into a heating pool, a cooling pool, and a misting pool by the combined enclosure of the partition members and the side wall of the working water tank, or by the partition members themselves. The water storage tank, heating pool, cooling pool, and atomizing pool are sequentially connected by a drainage channel to form a unidirectional flow path. A water-blocking structure is provided between the heating pool and the adjacent cooling pool. The water-blocking structure is located on the path of the assembly gap between the outer wall of the isolation cover and the side wall of the working water tank, and is constructed to block the path of water flowing directly between the heating pool and the cooling pool through the assembly gap between the outer wall of the isolation cover and the side wall of the working water tank. A heater is installed in the area of ​​the working water tank corresponding to the heating pool, and an atomizer is installed in the area corresponding to the atomizing pool. The heater and the atomizer are respectively coupled to the circuit system. The mist outlet channel connects the atomizing pool and the heating pool.

[0007] The structure of this utility model, by setting a water-blocking structure in the assembly gap path between the heating pool and the adjacent water pool, prevents insufficiently heated water from directly bypassing the water passage of the heating pool and flowing into the cooling pool or atomizing pool, thereby improving the sterilization reliability while maintaining the advantage of easy cleaning.

[0008] The humidifier of this utility model also provides the following auxiliary technical solutions:

[0009] As one implementation of the water-blocking structure, the water-blocking structure is a dam protruding upwards from the bottom of the working water tank. This design has the advantages of simple structure, easy processing, and easy integral molding with the base, resulting in good structural stability and durability. Furthermore, the water-blocking height of the dam is lower than or equal to the height of the drainage channel from the heating pool to the cooling pool, but higher than the height of the drainage channel from the storage tank to the heating pool. Since hot water rises and cold water sinks in the heating pool, this height design ensures that after the water is fully heated, it rises and overflows into the cooling pool through the designed drainage channel (water passage holes on the side wall). Even further, the top of the dam has a partially concave structure, with the concave portion laterally aligned with the drainage channel from the heating pool to the cooling pool, while the remaining portion is constructed higher than this drainage channel. The partially concave portion serves as a water passage, and the higher design of the rest of the dam further enhances the interception effect and guides the water flow path.

[0010] As another implementation of the water-blocking structure, the water-blocking structure is an elastic seal fixed to the outer wall of the isolation cover or the working water tank for filling the assembly gap; or, the water-blocking structure is an elastic seal that can be detachably installed on the path.

[0011] As another improvement, the drainage channel includes water passage holes formed on the partition member, achieving the purpose of simplicity and ease of processing.

[0012] As other improvement options, various partition structures are provided to adapt to different product forms and structural design requirements, including: the partition components used to separate the heating pool, cooling pool, and atomizing pool are all semi-enclosed components, and the heating pool, cooling pool, and atomizing pool are all formed by the partition components and the side wall of the working water tank together; or, the partition components used to separate the heating pool, cooling pool, and atomizing pool are all closed components formed by the side wall, and the heating pool, cooling pool, and atomizing pool are all formed by the partition components themselves independently; or, in the partition components used to separate the heating pool, cooling pool, and atomizing pool, at least a portion is a semi-enclosed component used to jointly enclose the corresponding water pool with the side wall of the working water tank, and the remaining portion is a closed component used to independently separate the corresponding water pool.

[0013] As another improvement, the water tank can be detachably mounted on the base to cover the water tank on the top surface of the base. The bottom of the water tank presses down on the isolation cover, and the water tank is equipped with a structure to avoid the mist outlet channel. The longitudinal restraint of the isolation cover is achieved by the weight of the water tank, which enhances stability and facilitates disassembly, cleaning, and maintenance.

[0014] As an alternative improvement, the water tank has built-in steps to cooperate with the side walls and / or partition components of the isolation cover to form a nested structure, thereby enhancing the sealing and positioning accuracy of the isolation cover and the water tank.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] See Figure 1a , 1b This embodiment provides a sterilization humidifier, including a base 100, a water tank (not shown in the figure), a mist outlet channel 400, and an isolation cover 300 that can be removed as a whole.

[0020] The base 100 contains an internal electrical system for controlling the overall operation of the humidifier. The top surface of the base 100 has an open water storage tank 110 and a working water tank 120. The water storage tank 110 contains a water outlet control device, such as a float valve, to control the amount of water supplied from the water tank to the water storage tank 110.

[0021] The isolation cover 300, with its bottom opening facing downwards, can be detachably placed within the working water tank 120. See [link / details]. Figure 2a , 2b The bottom structure of the isolation cover 300 divides the working water tank 120 into a heating pool 121, a cooling pool 122 and an atomizing pool 123 by a downwardly extending partition member 310.

[0022] exist Figure 2a , 2b In 2c, the atomizing pool 123 is independently separated by a closed cavity (i.e., atomizing chamber) formed by the side walls of the isolation cover 300, while the heating pool 121 and the cooling pool 122 are formed by the semi-closed partition member 310 on the isolation cover 300 and the side walls of the working water tank 120.

[0023] In another partitioning structure, such as Figure 3a , 3b 3c, The heating pool 121, cooling pool 122 and atomizing pool 123 are all formed by the semi-enclosed partition member 310 on the isolation cover 300 and the side wall of the working water tank 120. This structure relies more on the water-blocking structure design to ensure that the crossflow of insufficiently heated water is blocked.

[0024] More combinations are foreseeable, such as heating pool 121, cooling pool 122 and atomizing pool 123 being independently separated by a closed cavity formed by side walls on the isolation cover 300. This structure, combined with the water-blocking structure design, can achieve higher reliability; or, for example, cooling pool 122 is independently separated while heating pool 121 and atomizing pool 123 are enclosed together.

[0025] A unidirectional water flow path is formed between the water storage tank 110, heating tank 121, cooling tank 122, and atomizing tank 123 through preset water passage holes. A heater is installed in the area of ​​the working water tank 120 corresponding to the heating tank 121, and an atomizer is installed in the area of ​​the atomizing tank 123. The mist outlet channel 400 is used to mix the water mist generated by the atomizing tank 123 with the steam generated by the heating tank 121 before discharging it.

[0026] See Figure 1a A water-blocking structure is provided between the heating pool 121 and the adjacent cooling pool 122. The water-blocking structure is located on the path of the assembly gap between the outer wall of the isolation cover 300 and the side wall of the working water tank 120.

[0027] In this embodiment, the water-blocking structure is specifically a dam 124 formed by protruding upwards from the bottom of the working water tank 120. The top of the dam 124 has a partially concave structure, with the concave portion laterally aligned with the water passage from the heating pool 121 to the cooling pool 122, and the remaining portion higher than the drainage channel. This concavity constitutes the water-blocking height of the dam 124, which is designed to be lower than or equal to the height of the water passage from the heating pool 121 to the cooling pool 122, ensuring that heated water can overflow into the cooling pool 122. Simultaneously, the water-blocking height is significantly higher than the height of the water inlet channel 125 from the water storage tank 110 to the heating pool 121, ensuring that the water is fully heated.

[0028] During operation, water from the storage tank 110 flows into the heating pool 121 and undergoes high-temperature sterilization by the heater. Because hot water rises and cold water sinks, water in the lower layer of the heating pool that has not reached sterilization temperature is blocked by the dam 124 when attempting to flow through the assembly gaps to the cooling pool 122. All water in the heating pool must be fully heated before rising and overflowing into the cooling pool 122 through the higher-positioned water passage, thus ensuring thorough sterilization. For cleaning, simply remove the water tank and isolation cover 300; the water tank on the base 100 is completely open, and the dam 124 structure has no cleaning dead spots, facilitating thorough cleaning.

[0029] In another embodiment, a resilient sealing structure can be used to replace or coexist with the dam. For example, the water-blocking structure is a resilient seal 126 fixed to the outer wall of the isolation cover or the working water tank to fill the assembly gap, or a resilient seal 126 detachably installed on the path. The resilient seal 126, such as a silicone sealing strip, is compressed when the isolation cover 300 is placed on the working water tank 120, tightly filling the assembly gap between the outer wall of the isolation cover 300 and the side wall of the water tank to form a flexible seal.

[0030] Furthermore, the water tank is designed to be detachably pressed onto the base 100, forming a cover over the water storage tank 110 and the working water tank 120 on the top surface of the base. During installation, the bottom of the water tank presses downwards against the top of the isolation cover 300. Simultaneously, the water tank is provided with a clearance structure for the mist outlet channel 400. In addition, the bottom of the working water tank 120 may be provided with a stepped structure, forming a nested fit with the bottom of the partition member 310 of the isolation cover 300.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
