Description
Technical Field
[0001] This utility model relates to the field of air shower technology, and in particular to an air shower structure that integrates temperature regulation and alarm systems. Background Technology
[0002] With the development of air shower technology, various types of air shower equipment have been widely used in cleanrooms, laboratories, medical facilities, and electronics manufacturing environments with high cleanliness requirements. However, traditional air showers generally only have basic dust removal functions and lack the ability to intelligently sense and control the operating environment. Especially under high or low temperature conditions, it is difficult to maintain a stable temperature inside the air shower, which not only affects the comfort of personnel during the air shower process but may also lead to overheating, aging, or condensation of internal components, thereby causing system failures and reducing equipment reliability. In addition, existing air showers generally lack temperature anomaly monitoring and alarm mechanisms, failing to issue timely warnings when temperature control fails, posing safety hazards and hindering rapid response and handling by maintenance personnel.
[0003] A search revealed a patent for an intelligent, high-efficiency, constant-temperature air shower, publication number CN111266366B, published on December 10, 2021. This patent proposes installing a controller, a rotating platform, and a gravity sensor within the air shower area. It adjusts the distance between the air outlet and the user through an air shower outlet transfer mechanism, combining a blowing device and a return air system to maintain a constant temperature when the air shower air reaches the user, thereby improving comfort and ensuring the air shower effect. While this solution introduces the concept of "constant temperature," its temperature regulation relies on mechanical adjustments to the airflow and outlet distance. It lacks independent heating or cooling modules, as well as temperature sensors and a closed-loop temperature control system. Its "constant temperature" effect is limited by the ambient air intake temperature and cannot actively adjust the air shower airflow temperature in extreme ambient temperatures, resulting in limited temperature control capabilities. Furthermore, this solution lacks a temperature over-limit alarm function and a real-time monitoring and anomaly warning mechanism for the system's temperature control status, failing to meet the requirements of application scenarios with high operational safety and maintainability requirements.
[0004] Therefore, it is necessary to design an air shower structure that integrates temperature control and alarm systems to solve the above problems. Utility Model Content

The airflow circulation module includes airflow drive units installed on both sides of the air shower cavity, filter components connected to the airflow drive units, and multiple spray nozzles evenly distributed on the inner wall of the air shower cavity. The temperature monitoring module includes multiple temperature sensors distributed at different locations on the inner wall of the air shower chamber, a central processing unit connected to the temperature sensor signals, and a display and alarm unit electrically connected to the central processing unit.
[0007] Preferably, the airflow drive unit includes a centrifugal fan fixed to the side wall of the air shower chamber, a filter assembly connected to the air inlet of the centrifugal fan, and a flow divider connected to the air outlet of the centrifugal fan; the flow divider is provided with multiple flow guide baffles to divide the airflow into multiple streams and guide them to the nozzles.

Detailed Implementation
[0014] Reference Figures 1 to 3 An air shower structure integrating temperature regulation and alarm system is disclosed, comprising an air shower main module 110, a temperature control module, an airflow circulation module, and a temperature monitoring module. The specific composition of each module and their connection relationship are described below.
[0015] The air shower main module consists of a base frame and an air shower chamber 1 fixed to the base frame. A fresh air inlet port 11 is located at the top of the air shower chamber 1, connected to an external fresh air duct via a flange. An electric air valve is installed inside the fresh air inlet port. The opening and closing of the electric air valve is controlled by a central processing unit to adjust the fresh air input based on temperature changes inside the air shower chamber 1. A temperature control module is embedded in the inner wall of the air shower chamber 1 and includes a heat exchange device, a cooling component, a heating component, and a closed-loop temperature control circuit. The heat exchange device includes a heat-conducting plate, a heat pipe array attached to the inner side of the heat-conducting plate, and cooling and heating elements connected to both ends of the heat pipe array, respectively. The cooling elements are connected to the cooling component via refrigerant pipes, and the heating elements are connected to the heating component via wires. The refrigeration component is located at the bottom of the air shower chamber 1 and includes a compressor, a condenser, and an expansion valve, while the heating component is embedded in the side wall of the air shower chamber and consists of an electric heating wire and a silicon controlled rectifier voltage regulation module. The heat exchange device and the refrigeration component are all existing technologies, and the specific structure can be found on Baidu.
[0016] An airflow circulation module is installed on both sides of the air shower chamber 1, including an airflow drive unit 2, a filter assembly 3, and multiple nozzles 4. The airflow drive unit 2 consists of a centrifugal fan 21, a filter assembly, and a flow distribution chamber 22. The air inlet of the centrifugal fan 21 is connected to the filter assembly, and the air outlet is connected to the flow distribution chamber 22. The filter assembly 3 includes a filter element support 31, a high-efficiency filter 32, and a guide plate 33. The high-efficiency filter is snapped onto the filter element support. The guide plate has an arc-shaped design and multiple guide grooves to guide the airflow evenly into the high-efficiency filter. Multiple guide baffles are installed inside the flow distribution chamber to divide the airflow into multiple streams and guide them to the nozzles. The nozzles 4 are hinged to the side wall of the air shower chamber 1 via universal ball joints, and the outlet direction of the nozzles 4 is adjustable. The specific inlet end is connected to the diversion chamber via a flexible hose. A flow regulating valve is installed inside the flexible hose to achieve precise control of the airflow output from the nozzle. Whether or not a flexible hose is needed depends on the requirements; this part is not shown in the diagram. The temperature monitoring module includes multiple temperature sensors distributed at different locations on the inner wall of the air shower chamber 1, a central processing unit, and a display and alarm unit. The temperature sensors are fixed to different heights on the inner wall of the air shower chamber 1 via threaded connections and are equipped with waterproof sealing rings to ensure sealing performance. The signal output terminals of the temperature sensors are connected to the central processing unit via shielded cables. The central processing unit, embedded in the outer wall of the air shower chamber 1, includes a main control board, a storage module, and a communication module. The main control board has a built-in PID algorithm used to dynamically adjust the operating status of the heat exchange device based on the temperature data collected by the temperature sensors (this is an existing signal transmission system). It also includes an LCD display 5 and an audible and visual alarm light. The LCD display 5 is embedded in the outer wall of the air shower chamber 1 to display the temperature distribution inside the air shower chamber 1 in real time. The audible and visual alarm light is electrically connected to the LCD display 5. When an abnormal temperature is detected, the audible and visual alarm light is activated to prompt maintenance personnel to take timely measures.
[0017] During actual operation, air inside the air shower chamber 1 is drawn in by a centrifugal fan, purified by a filter assembly, and then distributed to multiple nozzles via a distribution chamber. The nozzles evenly spray the purified air into the air shower chamber 1. During this process, the heat exchange device regulates the temperature of the air inside the air shower chamber using cooling and heating elements. Temperature sensors collect real-time temperature data at different locations on the inner wall of the air shower chamber 1 and transmit the data to the central processing unit. The central processing unit analyzes the temperature data using a built-in PID algorithm and dynamically adjusts the operating status of the heat exchange device to ensure that the temperature inside the air shower chamber remains within the set range. If the temperature sensor detects that the temperature inside the air shower chamber 1 exceeds the set range, the central processing unit will trigger the display alarm unit. The LCD screen 5 will display specific temperature anomaly information, and simultaneously, a voice alarm and audible and visual alarm lights will activate to alert maintenance personnel to promptly investigate the problem.
[0018] Furthermore, the electric air valve inside the fresh air inlet is automatically controlled by the central processing unit to open and close based on temperature changes inside the air shower chamber 1, thereby adjusting the fresh air input and further optimizing the temperature stability inside the air shower chamber 1. The outlet direction of the jet nozzles can be adjusted via a universal ball joint to adapt to different usage needs. The high-efficiency filter in the filtration assembly effectively removes fine particulate matter from the air, and the arc design of the guide plate and the setting of the guide groove further improve the uniformity of airflow, thereby enhancing the air shower effect and user comfort.
[0019] Temperature sensors embedded in the inner wall of the air shower chamber 1 collect temperature data at different heights in real time and transmit the signals to the central processing unit via shielded cables. The central processing unit's built-in PID algorithm analyzes and processes the received temperature data, dynamically adjusting the operating status of the heat exchange device based on the deviation of the current temperature from the preset range. If the temperature inside the air shower chamber 1 is detected to be lower than the set value, the central processing unit controls the electric heating wire in the heating assembly to start, and adjusts the heating power through the thyristor voltage regulation module. The heating element transfers heat to the heat pipe array and diffuses it into the air shower chamber through the heat conduction plate. Conversely, if the temperature is higher than the set value, the compressor in the refrigeration assembly starts, and the refrigerant circulates under the action of the condenser and expansion valve. The cooling element absorbs heat and transfers the cooling capacity to the air shower chamber 1 through the heat pipe array, thereby achieving active regulation of the temperature inside the air shower chamber 1.
[0020] During temperature control, the electric air valve in the fresh air inlet port automatically adjusts its opening and closing degree according to the instructions of the central processing unit to introduce an appropriate amount of fresh air, further optimizing the temperature stability inside the air shower chamber 1. When the external ambient temperature changes significantly, the central processing unit can respond quickly and coordinate the working status of the cooling and heating components through a closed-loop temperature control circuit to ensure that the temperature inside the air shower chamber 1 is always kept within the set range.
[0021] The advantages of this utility model are that by embedding a heat exchange device in the inner wall of the air shower cavity and combining it with a cooling component and a heating component, the temperature inside the air shower cavity can be actively controlled, which solves the limitation of traditional air shower rooms relying on the ambient air temperature and ensures that a stable temperature range can be maintained under high or low temperature conditions. By setting up multiple temperature sensors and combining them with the PID algorithm of the central processing unit, real-time monitoring and dynamic adjustment of the temperature inside the air shower cavity were achieved, improving temperature control accuracy and response speed. By introducing a display alarm unit, an audible and visual alarm can be issued in a timely manner when an abnormal temperature is detected, and specific abnormal information can be displayed, which makes it easier for maintenance personnel to quickly locate the problem and take measures, thereby enhancing the safety and maintainability of the equipment. By optimizing the design of the airflow circulation module, using a centrifugal fan in conjunction with a flow divider and adjustable nozzles, the airflow distribution inside the air shower chamber is ensured to be uniform, thus improving the air shower effect and comfort.
[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
