Description

Technical Field

[0001] This utility model relates to a fabric testing device, and more particularly to a textile antibacterial testing device. Background Technology

[0002] A wide variety of fungi can easily grow on fabrics, and their growth is often influenced by factors such as fabric material, environmental conditions (e.g., temperature and humidity), and fabric processing techniques. Common fungi include molds and bacteria. Molds are common microorganisms on protein fiber fabrics such as silk. Under conditions of high relative humidity (e.g., above 85%), moderate temperature (5–50℃), and low pH (below 5), molds readily multiply on silk fibers. Common mold species include Aspergillus niger, Penicillium citrinum, Penicillium glaucum, Cladosporium, Aspergillus, Crescentella, Gum mold, Neurospora, and Trichoderma. Various bacteria can also easily grow on fabrics, including Staphylococcus aureus, Escherichia coli, Enterobacteriaceae, Pseudomonas aeruginosa, and Trichoderma. When these bacteria multiply on fabrics, they not only affect the fabric's hygiene properties but may also pose a threat to human health.

[0003] Therefore, many fabrics nowadays have been specifically enhanced with antibacterial properties to reduce the possibility of bacterial growth. To test the antibacterial properties of fabrics, antibacterial testing is necessary. The common testing steps are: setting up experimental and control groups; inoculating all fabric samples in both groups with microbial strains; culturing the experimental and control groups in the same environment; and observing and statistically analyzing the bacterial growth in both groups. Currently, most testing institutions rely on manual methods for fabric antibacterial testing, especially the inoculation step. This not only increases labor costs and testing efficiency but also increases unreliability. Summary of the Invention

[0004] This invention provides a device for testing the antibacterial properties of textiles, solving the problem that existing technologies require a large amount of manual operation in the fabric testing process, resulting in high labor costs and low testing efficiency.

[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: A textile antibacterial testing device, comprising: a testing tray, a first chamber and a second chamber, the two chambers being arranged side by side, each chamber including a base, a reduction motor located in the base, a rotating table driven by the reduction motor, a side plate and a top cover, the rotating axis of the rotating table being vertically arranged, and the testing tray being fixed on the rotating table; the first chamber also includes a spray system, the spray system consisting of a nozzle fixed on the top cover, a micro water pump, a hose, an electromagnetic three-way valve, a bacterial liquid tank and a clean water tank, the hose being used to connect the nozzle, the micro water pump, the electromagnetic three-way valve, the bacterial liquid tank and the clean water tank; the second chamber also includes an electric heater and a temperature sensor, the electric heater being a ceramic electric heating lamp, disposed on the top cover.

[0006] Before testing, sufficient bacterial solution must be added to the bacterial solution tank according to the type of bacteria to be tested, and the water tank must be filled with sufficient clean water. The testing tray in this invention is used to place fabric samples from both the experimental and control groups. Both the experimental and control fabrics must undergo disinfection, sterilization, and drying. The testing tray is then placed on the rotating platform within the first chamber, which is used to inoculate the fabric with the bacterial strain. The bacterial solution spraying program is then initiated. At this time, the reduction motor drives the testing tray to rotate slowly and uniformly, and the micro water pump also starts simultaneously. The electromagnetic three-way valve switches to the state of connection with the bacterial solution tank, allowing the nozzle to spray bacterial solution mist. After a certain period, the fabric on the testing tray is soaked with the bacterial solution, and the bacterial solution spraying program stops. The testing tray is then removed and transferred to the rotating platform within the second chamber, while the cleaning process of the first chamber is initiated. In the first chamber, the electromagnetic three-way valve switches to the clean water tank, and the micro water pump also starts. This allows the nozzles to clean the inside of the first chamber and the pipelines of the spray system, preventing bacterial growth. The cleaning program has a fixed duration. In the second chamber, the bacterial cultivation program is started. At this time, the geared motor drives the test tray to rotate slowly and uniformly, and the heater is also activated. The temperature sensor's set temperature can be freely adjusted to match the growth temperature of the experimental bacteria. The temperature sensor is used to detect the real-time temperature in the second chamber. When the temperature is too high, the heater is temporarily powered off; when the temperature is too low, the heater is powered back on, until the bacterial cultivation time meets the requirements. The bacterial cultivation program then closes, and the test tray is removed. At this point, the fabric sample on the test tray has completed bacterial culture and can be used for subsequent comparative testing. Therefore, this invention has the functions of autonomously inoculating fabric samples with bacteria and autonomously cultivating bacteria. Furthermore, because the test tray can be rotated continuously during inoculation and cultivation, the uniformity of inoculation is better, and the various environmental parameters of the cultivation are more uniform, thus reducing errors and ensuring the reliability of the test results.

[0007] Furthermore, the testing tray is a circular structure with several densely distributed protrusions on its upper surface, and a permanent magnet is fixed in its center; the rotating platform is made of ferromagnetic material. This technical solution allows the testing tray and rotating platform to be magnetically fixed, facilitating quick separation and docking; simultaneously, the protrusions on the upper surface of the testing tray can lift the fabric, ensuring good airflow on the underside of the fabric, which is beneficial for the cultivation and growth of aerobic bacteria and also helps to drain excess liquid.

[0008] Furthermore, the upper surface of the base has a structure that is high in the middle and low on the outer edges, forming a water-guiding channel at its edge. The water-guiding channel contains drainage holes connected to drainage pipes. This structure facilitates the guidance of waste liquid and wastewater to the water-guiding channel, and ultimately discharges them through the drainage pipes.

[0009] Therefore, this utility model has the following characteristics compared with the prior art: 1. This utility model has the function of autonomously inoculating fabric samples with bacteria and autonomously cultivating bacteria, which can effectively reduce manpower and improve detection efficiency; 2. At the same time, since the detection tray can be rotated at all times during the inoculation and cultivation process, the uniformity of inoculation will be better, and the various environmental parameters of cultivation will be more uniform, which can reduce the generation of errors and thus ensure the reliability of the detection results.

[0016] Example 1: See Figure 1 and Figure 3 A textile antibacterial testing device includes: a testing tray 100, a first chamber 201, and a second chamber 202, arranged side by side. Each chamber includes a base 210, a geared motor 220 located within the base, a rotating platform 230 driven by the geared motor, a side plate 240, and a top cover 250. The rotating platform's axis of rotation is vertically arranged, and the testing tray can be fixed on the rotating platform. The first chamber also includes a spray system 300, which consists of a nozzle 310 fixed on the top cover, a micro water pump 320, a hose 330, an electromagnetic three-way valve 340, a bacterial liquid tank 350, and a clean water tank 360. The bacterial liquid tank and the clean water tank are located at the rear of the first chamber, and the hose is used to connect the nozzle, the micro water pump, the electromagnetic three-way valve, the bacterial liquid tank, and the clean water tank. The second chamber also includes a heater 260 and a temperature sensor 270. The heater is a ceramic electric heating lamp and is located on the top cover.

[0017] Before testing in this embodiment, sufficient bacterial solution must be added to the bacterial solution tank according to the bacterial strain being tested, and the water tank must be filled with sufficient clean water. The testing tray in this embodiment is used to place the experimental group fabric samples and the control group fabric samples. Both the experimental and control group fabrics must undergo disinfection, sterilization, and drying treatment. The testing tray is then placed on the rotating platform inside the first chamber, which is used to inoculate the fabric with the bacterial strain. The bacterial solution spraying program is then started. At this time, the reduction motor drives the testing tray to rotate slowly and uniformly, and the micro water pump also starts simultaneously. The electromagnetic three-way valve switches to the state of connection with the bacterial solution tank, allowing the nozzle to spray bacterial solution mist. After a certain period, the fabric on the testing tray is soaked with the bacterial solution, and the bacterial solution spraying program stops. Then, the testing tray is removed and transferred to the rotating platform inside the second chamber, while the cleaning process of the first chamber is started. In the first step, the electromagnetic three-way valve switches to the state of connection with the clean water tank, and the micro water pump also starts simultaneously. This allows the nozzles to clean the inside of the first chamber and the pipelines of the spray system, preventing bacterial growth. The cleaning program has a fixed working time. In the second chamber, the bacterial cultivation program is started. At this time, the geared motor drives the detection tray to rotate slowly and uniformly, and the electric heater is also activated. The set temperature of the temperature sensor can be freely adjusted to match the growth temperature of the experimental bacterial strain. The temperature sensor is used to detect the real-time temperature in the second chamber. When the temperature is too high, the electric heater is temporarily powered off; when the temperature is too low, the electric heater is powered back on, until the bacterial cultivation time meets the conditions. The bacterial cultivation program is then closed, and the detection tray is removed. At this point, the fabric sample on the detection tray has completed bacterial culture and can be used for subsequent comparative testing. Therefore, this embodiment has the functions of autonomously inoculating fabric samples with bacterial strains and autonomously cultivating bacteria. At the same time, because the detection tray can be rotated continuously during inoculation and cultivation, the uniformity of inoculation is better, and the various environmental parameters of cultivation are more uniform. This reduces the occurrence of errors and ensures the reliability of the test results.

[0018] See Figure 1 and Figure 2 The testing tray has a circular structure with several densely packed protrusions 110 on its upper surface, and a permanent magnet 120 is fixed in the center. The rotating platform is made of ferromagnetic material. This technical solution allows the testing tray and rotating platform to be magnetically fixed, facilitating quick separation and docking. Simultaneously, the protrusions on the upper surface of the testing tray can lift the fabric, ensuring good airflow on the underside of the fabric, which is beneficial for the cultivation and growth of aerobic bacteria and also helps to drain excess liquid.

[0019] See Figure 1 The upper surface of the base has a structure that is high in the middle and low on the outer side, which forms a water inlet trough 211 at its edge. The water inlet trough is provided with a drain hole 212, which is connected to a drain pipe 213. This structure is conducive to guiding waste liquid and wastewater to the water inlet trough and finally discharging them through the drain pipe.

[0020] See Figure 4 The side panel has a four-sided structure, with the front side being entirely made of transparent material. A flip cover 241 is pivotally connected to the front side panel, and the edge of the flip cover is provided with a sealing strip 242.

[0021] See Figure 1 The first compartment is also equipped with a bacterial distribution button 10, a cleaning button 20, and a first timer 30. The bacterial distribution button can control the electromagnetic three-way valve to connect to the bacterial liquid tank and start the micro water pump, and at the same time start the geared motor. The cleaning button can control the electromagnetic three-way valve to connect to the clean water tank and start the micro water pump. The first timer can be used to set the working time of the micro water pump and the geared motor.

[0022] See Figure 1 The second compartment is also equipped with a start button 40, a temperature control knob 50, and a second timer 60. The start button is used to power the geared motor, the heater, and the temperature sensor. The temperature control knob is used to set the detection temperature of the temperature sensor. The second timer is used to control the working time of the heater and the geared motor.

[0023] This invention can be modified in many ways, as will be apparent to those skilled in the art, and such modifications are not considered to depart from the scope of this invention. All such modifications that are obvious to those skilled in the art are included within the scope of these claims.
