Description

Technical Field

[0001] This utility model relates to the field of environmental simulation test chambers, and in particular to a large-scale space-adjustable multifunctional test chamber. Background Technology

[0002] In recent years, with the increasing awareness of public health and safety, the concept of sterilization and disinfection has become increasingly popular, and disinfection products are being accepted and valued by more and more households. As a key indicator for evaluating the performance of disinfection products, air disinfection effectiveness is a mandatory test item in the hygiene and safety evaluation report of disinfection products. According to existing national or industry standards for disinfection products, simulated field air disinfection experiments must be conducted in a test chamber, and the test chambers must have the same requirements—two adjacent test chambers with identical structure and performance parameters. However, the required space size of the test chamber may vary depending on the type of disinfection product, with 20 cubic meters being a common requirement. and 30 Primarily for large spaces, such as those specified in GB28235-2020 "Hygienic Requirements for Ultraviolet Sterilizers" and WS / T 648-2019 "General Hygienic Requirements for Air Sterilizers," which require a minimum of 20... Test chamber; According to the "WS / T 10009-2023 Test Methods for Disinfection Products", the requirements can be divided into ≥1 Test chamber and 20 ~30 Test chambers, etc. To simultaneously meet the testing requirements of air disinfection experiments for different types of disinfection products, laboratories need to construct test chambers of varying sizes. For third-party testing agencies or other companies, this requires not only significant investment in test chamber construction but also additional site costs, resulting in a relatively high overall investment and hindering cost control. Utility Model Content

[0003] The purpose of this invention is to provide a large-scale, adjustable, multi-functional test chamber that can be configured to have two adjacent test chambers with identical structure and performance parameters through a movable partition wall, thereby meeting the air disinfection effect testing needs of different types of disinfection products and reducing the cost for enterprises to build test chambers.

Hollow hanging rails are installed along the long side of the test chamber body at the connection between the top plate and the side plate and at the connection between the bottom plate and the side plate. Isolation walls that divide the test chamber body into symmetrical left and right chambers are installed on the hanging rails, with each chamber corresponding to one isolation wall. Hanging wheels that extend into the hanging rails to make the isolation walls movable are installed on the isolation walls. Sealing strips that seal with the inner wall of the test chamber and the hanging rails are installed around the isolation walls. Air inlets, ultraviolet lamps and lighting lamps are provided on the top plate of each symmetrical left and right chamber. Each chamber's front panel is provided with a sealed door and a touch screen controller panel. Each chamber's back panel is provided with an exhaust vent. Each chamber's side panel is provided with a transfer window, operating gloves, sampling port and viewing window.

[0005] The large-scale adjustable multifunctional test chamber of this invention uses a partition wall that moves along a rail on the test chamber via casters to create adjacent test chambers with identical structures.

Disinfection products are placed into the test chamber through the sealed door, which is then closed to seal the chamber. A touchscreen controller panel controls the air inlet, UV lamp, lighting, and exhaust vents to create adjacent test chambers with identical performance parameters for sterilization. Then, wearing operating gloves, samples are taken through a viewing window, transfer window, operating gloves, and sampling port. This design caters to the air disinfection effect testing needs of different types of disinfection products, thereby reducing the cost of building test chambers for enterprises. Furthermore, this test chamber has a simple structure, is easy to operate, and has a relatively low cost. It is not only suitable for testing the spatial disinfection effect of various disinfection products as specified in national standards, but also meets the testing needs of other types of products requiring test chambers of different sizes, demonstrating good social and economic benefits.

[0022] A large-scale, space-adjustable, multi-functional experimental chamber, such as Figure 1 - Figure 4 As shown, the test chamber includes a main body 1. Hollow hanging rails 14 are installed along the long side of the test chamber at the connection between the top plate and the side plate and at the connection between the bottom plate and the side plate. Isolation walls 2 are installed on the hanging rails to separate the test chamber into left and right symmetrical chambers. Each chamber corresponds to one isolation wall. Hanging wheels 13 are installed on the isolation walls to allow the isolation walls to move by extending into the hanging rails. Sealing strips 18 are installed around the isolation walls to seal against the inner wall of the test chamber and the hanging rails. Each left and right symmetrical chamber has an air inlet 8, an ultraviolet lamp 10 and a lighting lamp 11 on the top plate. Each chamber has a sealed door 6 and a touch screen controller panel 16 on the front panel. Each chamber has an exhaust vent 9 on the back panel. Each chamber has a transfer window 4, an operating glove 3, a sampling port 5 and a viewing window 12 on the side panel.

[0023] The main body of the test chamber 1 is separated into two symmetrical chambers by an isolation wall. Each chamber corresponds to one isolation wall, and a sliding handle 17 is installed on the isolation wall. The handle 17 can be installed on the isolation wall with screws, making it easier to move the isolation wall and obtain two adjacent test chambers with the same structure. In addition, two sets of hanging wheels 13 are installed at each of the left and right ends, embedded in the grooves 19 of the isolation wall. The hanging wheels 13 are fixed in the upper and lower hanging rails 14 on the inner wall of the test chamber. Furthermore, a sealing strip 18 is installed around the four sides of the isolation wall 2. The sealing strip 18 is made of Teflon. An elastic rubber edging is set around the Teflon sealing strip and pressed against the inner wall of the test chamber and the hanging rail. The sealing strip is placed in the groove and pressed against the outer wall of the hanging rail, so that it is in seamless contact with the test chamber wall and the upper and lower hanging rail guide tubes to ensure the airtight performance of the test chamber during use.

The operating gloves are sealed rubber gloves designed for wearing and inserting into the main body of the test chamber. Two sealed operating gloves (one left and one right) are provided.

[0027] like Figure 5 As shown, an air circulation system 21 and an exhaust fan 22 are installed on the outside of the main body of the test chamber. One end of the air circulation system is connected to the air inlet through a first pipe, and the other end is connected to both the air inlet and the exhaust fan through a three-way pipe. Switch valves 23 are installed on the first pipe, the air circulation system side, and the exhaust fan side of the three-way pipe. These valves are electrically operated. The air circulation system 21 and the exhaust fan 22 enable air to circulate between the air inlet and the exhaust fan, forming an air circulation system.

[0028] Lighting lamps 11 and ultraviolet lamps 10 are mounted on the top plate of each chamber via clips or screws. The ultraviolet lamps 10 sterilize the test chambers. Each chamber near the sealed door is fitted with a socket 15, which is electrically connected to a touchscreen controller panel. The touchscreen controller panel is also electrically connected to a battery installed on one side of the test chamber, allowing for charging via a connection to AC power. The touchscreen controller panel is electrically connected to the lighting lamps, ultraviolet lamps, air circulation system, exhaust fan, valves, and stirring fan. Controlling these components via the touchscreen controller panel allows for sterilization of adjacent test chambers with identical performance parameters.
