Description

Technical Field

[0001] This utility model relates to the field of humidifier technology, and in particular to a pumpless, integrated, mist-free humidifier. Background Technology

[0002] Most existing humidifiers have their water tanks located at the bottom. For mist-free humidifiers, a water pump draws water from the bottom tank to the top of the evaporative cooling pad for spraying. Once the pad or filter is saturated, excess water flows back to the bottom tank, where it is then pumped back to the pad for continuous spraying. However, this recirculating spraying method easily leads to the accumulation of dirt and bacteria in the bottom tank, making it difficult to ensure clean and hygienic mist output. To address this, patent number CN202221384964.7 proposes a clean and wastewater separation type mist-free humidifier. This humidifier utilizes two separate water tanks: the first tank serves as the main water storage tank, and the second tank collects the returned water from the bottom during the recirculating spraying process. This ensures that the water in the first tank does not participate in the recirculating spraying, maintaining a cleaner and more hygienic mist-free humidification effect. Controlling the discharge of water from the main water tank requires the use of electrical components such as solenoid valves. The solenoid valve requires a water level sensor in the second water tank at the bottom to detect the water level and transmit the signal to the solenoid valve for operation. This system uses numerous electrical components, demands high waterproofing for the wiring, and has high manufacturing costs, making it unsuitable for low-cost, top-tank humidifiers. Therefore, further improvements are needed.

[0003] Therefore, the applicant designed a low-cost top-mounted water tank humidifier, such as the water control structure of a low-cost top-mounted water tank humidifier disclosed in patent number CN202420255120.5. However, further research revealed the following drawbacks of this structure: its shell includes a bottom water tank (combined upper and lower sections), an outer shell, an upper connecting seat, and a main water tank; the assembly of multiple shell structures requires additional assembly parts, leaving room for cost reduction design; furthermore, the main water tank is mounted on the upper connecting seat, limiting its volume; the air duct extends from the lower side air intake to the circumferential air outlet of the water tank, resulting in a relatively long air duct and room for improvement in the space utilization of the mist-free air outlet. Therefore, further improvements are needed. Utility Model Content

The drain channel 40 is equipped with a drain transition box 70 at the outlet end; the drain transition box 70 has a drain outlet 71, and the drain outlet 71 is equipped with a drain plug 72; the bottom water tank 21 is equipped with a float assembly 80; a water level swing rod 73 is installed below the drain outlet 71, and one end of the water level swing rod 73 extends upward toward the float assembly 80. When the water level in the bottom water tank 21 rises, the float assembly 80 floats up and can lift the water level swing rod 73; the water level swing rod 73 can be lifted to abut against and block the drain plug 72.

[0026] The beneficial effects of this utility model are: 1. High Integration and Cost Optimization: The design adopts an integrated shell 10 combined with internal partitions 12, highly integrating the water tank chamber 13, blower chamber 14, and evaporative cooling curtain chamber 15 into a single shell, greatly reducing the number of multiple assembled shell components and connectors required in traditional humidifiers. This integrated structure simplifies the assembly process and reduces material and assembly costs.

[0027] 2. Purely mechanical water level control: stable, reliable, and cost-effective. A purely mechanical automatic water level control mechanism is creatively constructed using a float assembly 80, a water level lever 73, and a drain plug 72. When the water level in the bottom tank 21 rises, the float rises, driving the lever to directly block the drain outlet 71. This process eliminates the need for electrical components such as solenoid valves and water level sensors, as well as their associated circuits. This significantly reduces manufacturing costs and fundamentally avoids the risks of electrical component failures in aquatic environments (such as short circuits and corrosion) and complex wiring and waterproofing requirements. The system operates more stably and reliably, with a longer lifespan.

[0028] 3. Optimized air duct and space utilization to improve humidification efficiency: Through reasonable chamber partitioning, the wet curtain chamber 15 and the blower chamber 14 are arranged vertically, forming a more compact and efficient vertical air duct. This structure shortens the airflow path, reduces wind resistance, and allows the airflow to pass through the wet curtain more concentratedly and efficiently, thereby improving the water evaporation efficiency and humidification capacity, while also making the overall structure more compact.

[0029] In this embodiment, the evaporative cooling pad assembly 30 includes an evaporative cooling pad body 31, an evaporative cooling pad support 32, and an evaporative cooling pad top cover 33. The evaporative cooling pad body 31 is installed on the outer periphery of the evaporative cooling pad support 32. The evaporative cooling pad top cover 33 is installed above the evaporative cooling pad support 32 and has several drainage holes. Integrating the evaporative cooling pad body 31, support, and top cover into a single evaporative cooling pad assembly 30 makes installation, disassembly, and daily cleaning and maintenance very convenient. Users can easily remove the entire assembly for cleaning or replacement. The several drainage holes on the evaporative cooling pad top cover 33 can disperse and evenly spray water from the drain channel 40 onto the evaporative cooling pad body 31 below, ensuring that all parts of the evaporative cooling pad are fully wetted, avoiding localized dryness, thereby maximizing the evaporation area and improving humidification efficiency.

[0030] Furthermore, the top cover 33 of the evaporative cooling pad is provided with a water receiving groove 34; the water receiving groove 34 is located below the transition box. The design of the water receiving groove 34 can effectively receive the water flowing out from the drain transition box 70 and smoothly guide it into the drain hole, preventing the water flow from directly impacting the surface of the top cover 33 of the evaporative cooling pad and causing water to splash, ensuring the cleanliness of the internal working environment, and further promoting the uniformity of water distribution.

[0031] In this embodiment, the water level lever 73 includes a lever shaft 731, a lever sealing block 732, and a lever extension arm 733. The lever shaft 731 is rotatably connected to the drain transition box 70, and the lever extension arm 733 extends upward toward the float assembly 80. The lever sealing block 732 is located below the drain plug 72 and can seal the drain plug 72. Through the lever structure design of the shaft, extension arm, and sealing block, the small vertical displacement of the float is amplified and converted into a precise sealing action of the sealing block, making the water level control response sensitive and the action reliable.

[0032] In some embodiments, the drainage transition box 70 consists of two shell structures that are joined together. The split shell structure simplifies mold manufacturing and facilitates the molding and arrangement of the internal structure, thereby improving production and assembly efficiency.

[0033] In this embodiment, the outer cylinder wall 11 is provided with an air outlet structure 16 on the outside of the blower chamber 14; an air inlet structure 22 is provided below the outer cylinder wall 11 or on the base 20. The clearly defined bottom air inlet and upper side air outlet structure 16, together with the internal blower chamber 14 and wet curtain chamber 15, constitute a complete and smooth vertical air circulation path, ensuring that air is forced through the wet curtain, resulting in high humidification efficiency and effective delivery of humidified air to distant locations.

[0034] In this embodiment, the base 20 is provided with a water tank annular wall 23 and a connecting outer wall 24, the water tank annular wall 23 forming a bottom water tank 21; the lower end of the outer cylinder wall 11 can be snapped onto the connecting outer wall 24. The structure is stable and assembly is simple: the base 20 forms a stable structure through the water tank annular wall 23 and the connecting outer wall 24, and the snap-fit ​​connection with the outer cylinder wall 11 is simple and reliable, requiring no or only a few screws to fix the main structure, greatly facilitating production and after-sales maintenance. The functional zoning is clear: this design clearly divides the water storage area of ​​the bottom water tank 21 and the connection area with the shell, resulting in a compact and reasonable structure.

[0035] Specifically, the air intake structure 22 is an air intake slot structure formed between the water tank annular wall 23 and the connecting outer wall 24. The structure is integrated, requiring no additional parts. The air intake function is achieved through the structural design itself, eliminating the need for additional air intake grilles or mesh covers, further saving costs and assembly steps.

[0036] In this embodiment, the float assembly 80 includes a float body 81 and a float limiting frame 82; the float limiting frame 82 is detachably installed in the bottom water tank 21; the float body 81 floats up and down within the float limiting frame 82. The float limiting frame 82 ensures that the float body 81 can only float up and down along a preset vertical path, preventing it from tilting, getting stuck, or deviating, thereby ensuring that the water level swing rod 73 can be triggered accurately and reliably, improving the stability of the water level control system.

[0037] In this embodiment, a partition plate 17 is detachably installed on the lower side of the partition plate 12; the partition plate 17 is used to install electronic components and the fan assembly 60; an air guide shroud 18 is installed below the partition plate 17; the fan assembly 60 is installed between the air guide shroud 18 and the partition plate 17. The partition plate 17 forms an independent mounting plane, centrally installing all electronic components such as the control center 50 and the fan motor, and completely isolating them from the water circuit of the wet curtain chamber 15 below, greatly improving the electrical safety performance of the product and effectively preventing moisture and splashes. The air guide shroud 18 and the partition plate 17 together constitute a high-efficiency fan casing, which can concentrate and guide the airflow generated by the fan, reduce eddies and wind pressure loss, and improve airflow efficiency. At the same time, the modular design allows for the maintenance and replacement of electronic components and the fan without disassembling the entire machine, making maintenance convenient.

[0038] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
