Humidifier

This design is a reimagining inspired by @施密特触发器's 加湿器, incorporating an air filter module, Type-C power delivery, an enlarged casing, improved airflow channels, and tool-free modular assembly.

Its fully modular design facilitates future expansion with a PWM speed control module, a DC power module, a rocker switch module, an ESP32C3 module (potential for incompletion), a microswitch module, an 80cm fan mount, and a variable voltage Type-C power adapter module (XSP06), allowing for customized configurations. Subsequent module additions will primarily replace the Type-C module (Figure 2) within this version, minimizing disruption to the core structure. Any adjustments will ensure compatibility with the existing framework.

As this is my inaugural 3D modeling endeavor, imperfections are to be expected. Your understanding is appreciated.

Excluding the pet waterer, additional materials required are:

1. A 90cm fan, 25cm in height. Voltage should match your chosen power adapter; I used a 12V fan. An 80cm fan mount will be released this weekend. If you already own an 80cm, 25cm fan, no additional purchase is necessary; simply print the provided files;

2. A Type-C power adapter, model PDC004-PD. Ensure voltage compatibility with your fan. An XSP06 adjustable voltage Type-C power adapter module may be added later;

3. A humidifier filter compatible with Philips HU4706 humidifiers;

4. An air filter, VC20 Delmar vacuum cleaner air filter. The air filter is optional;

Due to the shrinkage inherent in printing materials, three baffles are provided to ensure secure Type-C fitting. Insert the baffles into the Type-C module based on your printed components.

The air filter mounting mesh is secured via screw threads. Initial installation may be tight. If omitting the air filter, the mesh can be directly inserted into the casing. Alternatively, you may attach your own dust filter to prevent debris entry.

Install the fan and air duct as shown above. Note the inward airflow direction in the design; avoid incorrect orientation.

Purchased filters may not be perfectly circular, potentially hindering alignment with the air duct. A humidifier filter support is provided; use as needed.

The above diagram illustrates humidifier lid installation.

Final assembly illustration.

The fan power supply is not soldered to the Type-C board to accommodate the likely addition of a PWM speed control module. For future upgrades, consider using an XH2.54 female connector, as shown below.

To reiterate: The modular design and aesthetic goals, coupled with my nascent 3D modeling skills, mean the design of future modules remains under development. While I intend to include a PWM speed control module, a DC power module, a rocker switch module, a microswitch module, and a variable voltage Type-C power adapter module, project completion is not guaranteed.
