[0033] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include: one or more of such features. In the description of the present utility model, "a plurality" means two or more unless otherwise specifically defined.
[0034] Now, a device for detecting the antibacterial performance of clothing fabrics provided by an embodiment of the present utility model will be described.
[0035] Please refer to Figures 1 to 5 , a device for detecting the antibacterial performance of clothing fabrics, comprising: a substrate 1, an upper housing 4, and at least one channel 6 vertically penetrating the upper housing 4 provided at the top of the upper housing 4.
[0036] The upper surface of the substrate 1 is a plane, and the bottom of the upper housing 4 matches the upper surface of the substrate 1, so that the bottom of the upper housing 4 can be closely attached to the upper surface of the substrate 1.
[0037] At least one channel 6 vertically penetrating the upper housing 4 is provided at the top of the upper housing 4. When the upper housing 4 is attached to the substrate 1, the corresponding part on the substrate 1 to the channel 6 can be exposed. When the clothing fabric sample 3 to be detected is placed between the substrate 1 and the upper housing 4, the corresponding part of the clothing fabric sample 3 to the channel 6 can be exposed.
[0038] Place the culture medium inoculated with the test bacteria in the channel 6, then put the whole utility model into a constant temperature and humidity incubator set at 37°C with a humidification function for 24 hours, and then take it out for comparative observation.
[0039] One way to keep the upper housing 4 attached to the substrate 1 is: a sealed cavity 9 is formed between the substrate 1 and the upper housing 4. A quick-connect nozzle 10 and an air inlet 11 are provided on the side of the upper housing 4. A one-way valve core is provided inside the quick-connect nozzle 10, and the one-way valve core only allows the air inside the upper housing 4 to flow out through the quick-connect nozzle 10. A threaded plug 12 is installed at the air inlet 11 by threading.
[0040] During use, connect the vacuum pump to the quick-connect nozzle 10. The vacuum pump evacuates the inside of the sealed cavity 9 between the substrate 1 and the upper housing 4 to vacuum, and presses the substrate 1 and the upper housing 4 together by atmospheric pressure. When it is necessary to remove the clothing fabric sample 3, just remove the threaded plug 12.
[0041] One way to keep the upper housing 4 attached to the substrate 1 is: the substrate 1 can be made of metal, and the upper housing 4 is made of magnetically adsorbable material.
[0042] Compared with the prior art, the clothing fabric antibacterial performance detection device provided by the present utility model, by setting the substrate 1 and the upper housing 4, at least one channel 6 vertically penetrating the upper housing 4 is provided at the top of the upper housing 4. The substrate 1 and the upper housing 4 are closely attached under the action of vacuum. When the clothing fabric sample 3 to be detected is placed between the substrate 1 and the upper housing 4, the corresponding part of the clothing fabric sample 3 to the channel 6 can be exposed, so as to detect the antibacterial performance of the clothing fabric sample 3.
[0043] For example, three groups of channels 6 can be set, one of which can be used as a control group, and the other two can be used for experiments with different bacterial colonies.
[0044] In another embodiment of the present utility model, please refer to Figures 1 to 4 , a support block 2 is fixedly connected to the bottom of the substrate 1. The support block 2 is used to support the substrate 1, which is beneficial to the placement of the substrate 1 in the constant temperature and humidity incubator.
[0045] In another embodiment of the present utility model, please refer to Figures 1 to 4 , a notch 5 parallel to the outer contour of the upper housing 4 is provided at the top of the upper housing 4, and the upper housing 4 can be grasped through the notch 5 and the outer contour of the upper housing 4.
[0046] In another embodiment of the present utility model, please refer to Figures 1 to 4 , a first seal 7 is fixedly provided at the bottom end of the outer wall forming the channel 6, and a second seal 8 is fixedly connected to the inner bottom contour line of the upper housing 4. When the upper housing 4 is attached to the substrate 1, the sealing performance of the sealed cavity 9 can be maintained.
[0047] In another embodiment of the present utility model, please refer to Figures 1 to 4 , a water blocking cover 13 is provided at the upper port of the channel 6. The water blocking cover 13 can be breathable and water blocking, avoiding the liquefied water droplets inside the constant temperature and humidity incubator from dripping onto the clothing fabric sample 3 inside the channel 6. Specifically, the water blocking cover 13 includes: a first conical shell 131, a second conical shell 132, an annular member 133, and a handle plate 134.
[0048] The bottom end of the first conical shell 131 has a flat part. The tip of the second conical shell 132 faces upward, and the bottom end of the second conical shell 132 is fixedly connected to the flat part of the first conical shell 131. The annular member 133 is fixedly connected to the top opening of the first conical shell 131. A handle plate 134 is fixedly connected to the inner side of the annular member 133. Mesh holes are provided on the sides of both the first conical shell 131 and the second conical shell 132.
[0049] By providing mesh holes on the sides of both the first conical shell 131 and the second conical shell 132, the gas flow inside the channel 6 can be ensured. And the liquefied water droplets inside the constant temperature and humidity incubator drip onto the first conical shell 131 and the second conical shell 132, and will gather at the junction of the first conical shell 131 and the second conical shell 132 and will not flow to the mesh holes.
[0050] In another embodiment of the present utility model, please refer to Figures 1 to 4 , the cross-section of the channel 6 is circular.
[0051] In another embodiment of the present utility model, please refer to Figures 1 to 4 , the substrate 1 is made of a stainless steel panel, which is easy to clean.
[0052] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
