Transport vehicle for combined fan filter module

Abstract

A transport vehicle incorporating a fan and filter module includes a pressurized cleanroom box mounted on a platform. Handles and multiple movable and fixed wheels are located at the rear, front, and lower sides of the transport vehicle. The pressurized cleanroom box is equipped with a quick-change battery module electrically connected to an electronic control device. A fan and a precision filter are located at the top of the pressurized cleanroom box. Powered by the fan, the air blown by the fan passes through the precision filter, ensuring that the air entering the pressurized cleanroom box is clean and dust-free. This creates a negative pressure inside the pressurized cleanroom box, continuously blowing downwards, so that the bottom and surrounding areas of the transport vehicle are continuously exposed to clean air. During movement, the continuous downward and outward blowing of clean air effectively maintains the cleanliness of the cleanroom box during transport between cleanrooms.

Claims

1. A transport vehicle incorporating a fan filter module, comprising: A transport vehicle is provided with a platform and a handle at the rear of the platform. Multiple movable wheels are located at the lower front or rear of the platform, and multiple fixed wheels are located at the lower rear or front of the platform, allowing the operator to manually push the transport vehicle on the ground using the handle. A pressurized cleanroom is also provided, mounted on the platform of the transport vehicle. The pressurized cleanroom is equipped with a power supply and electrically connected to an electronic control device. A fan is located on the top of the pressurized cleanroom, and a precision filter is located below the fan. The fan is electrically connected to the power supply. The air blown by the fan is filtered through the precision filter, making the gas entering the pressurized cleanroom clean and creating a positive pressure inside the pressurized cleanroom clean. The bottom plate of the pressurized cleanroom clean has an air outlet, which allows the pressurized clean gas inside the pressurized cleanroom clean to be blown downwards and outwards to create a negative pressure. This effectively prevents dust particles from entering and adhering to the bottom and surrounding areas of the transport vehicle during movement, ensuring the cleanliness and dust-free effect of the pressurized cleanroom clean.

2. The transport carrier for the combined fan filter module as described in claim 1, wherein the pressurized cleanroom is provided with an openable and closable door on one side, and the pressurized cleanroom is provided with several shelves inside, each shelf having a plurality of through holes for airflow, so that clean and dust-free gas flows sequentially from top to bottom through each shelf and is then blown out from the outlet holes to form a negative pressure.

3. The transport carrier combining the fan and filter module as described in claim 2, wherein the power supply device includes a first battery module and a second battery module, the first battery module and the second battery module being connected in parallel to the electronic control device and jointly connected to the fan for power supply, so that when one battery module is replaced, the other battery module continues to supply power to maintain the operation of the fan, ensuring that the positive pressure airflow of the pressurized cleanroom and the continuous blowing of the air outlet are not interrupted due to battery replacement, and preventing dust particles from entering due to instantaneous pressure loss during battery replacement.

4. The transport vehicle for the combined fan filter module as described in claim 2, wherein the power supply device may be a quick-change battery module.

5. The transport vehicle for the combined fan filter module as described in claim 4, wherein the quick-change battery module is disposed on the top surface of the pressurized cleanroom.

6. The transport carrier for the combined fan filter module as described in claim 4, wherein the quick-change battery module is disposed on one of the left, right, or rear sides of the pressurized cleanroom that is not equipped with the door.

7. The transport vehicle for the combined fan and filter module as described in claim 2, wherein a temperature and humidity controller is provided on the top surface of the pressurized cleanroom, and the temperature and humidity controller is electrically connected to the electrical control device.

8. The transport vehicle for the combined fan filter module as described in claim 2, wherein the precision filter may be an FFA series precision filter.
