Detailed Description

Examples

A cleanliness detection device, as shown in fig. 1, 2, 3, 4 and 5, comprising a detection test paper 1 and a storage box 2 for storing the detection test paper 1, wherein the storage box 2 comprises a box body 201, a placing unit 202 arranged in the box body 201 and used for placing the detection test paper 1, a comparison unit 203 arranged in the box body 201 and used for comparing with the detection test paper 1, and a storage unit 204 arranged in the box body 201 and used for placing the detection test paper 1 after comparison; the storage box 2 further includes a box cover 205 hinged to a side end of the box body 201 and configured to form a sealed space with the box body 201.

In this embodiment, the test strip 1 is made of a water-soluble material, so that the test strip 1 can be removed when being washed inside the system even if the test strip falls into the system carelessly in the testing process, and the problems of system blockage and the like cannot be caused. The placing unit 202 is configured to place the unused test paper 1, the storing unit 204 is configured to place the test paper 1 after detection is completed, and after the test paper 1 after detection is placed and fixed in the storing unit 204, gray scale comparison can be directly performed with the color block on the comparing unit 203, and detection data can be recorded in time. The process is simple to operate, the device can be used for storing the unused detection test paper 1 to prevent pollution or moisture, and can be used for storing the detection test paper 1 after detection is finished in time, so that data can be recorded and stored more timely and rapidly.

In this embodiment, the placing unit 202 includes a placing groove 202a disposed on the box body 201, a taking groove 202b disposed at a side end of the box body 201 and connected to the placing groove 202a, and a fixing column 202c disposed in the taking groove 202b for fixing the test strip 1. Correspondingly, the test strip 1 includes a detection area 101, a fixing area 102 disposed at a side end of the detection area 101, and a fixing hole 103 disposed on the fixing area 102 and connected to the fixing column 202c in a manner of being sleeved on the fixing column 202 c. The test strip 1 further includes a recording region 104 disposed at a side of the detection region 101 different from the fixed region 102.

In this embodiment, in order to reduce the risk that the test strip 1 is easily dropped by being held by hand, the fixing region 102 is designed on the basis of a conventional square or rectangular test paper, and a fixing hole 103 is formed in the fixing region 102, and the advantages of the fixing region 102 at least include: firstly, in an actual test scene, a worker can complete a series of actions such as taking, wiping, placing and the like by holding the fixed area 102, and the holding can be more stable due to the protruding structure similar to an ear formed by the fixed area 102, so that the risk of falling is reduced; secondly, the fixing holes 103 are formed to ensure that all the test strips 1 are stably fixed and kept in the same side when the unused test strips 1 are stored, and are more convenient to take out, and only the fixing area 102 needs to be lifted from the taking groove 202b until the fixing holes 103 are removed from the fixing columns 202 c; thirdly, as the staff can complete a series of actions such as taking, wiping, placing and the like by holding the fixed area 102, the whole process does not need to be in contact with the detection area 101, and the detection result is prevented from being influenced by the pollution of the detection area 101. In this embodiment, in order to facilitate the taking out of the test strip 1, the taking groove 202b is communicated with the edge of the box body 201, so that a worker can take the test strip directly from the side end of the taking groove 202b, i.e. the head of the fixing region 102. The recording area 104 can record time, gray scale and other parameters after the test paper 1 completes the test, so that the timeliness is higher, and the test data is more accurate.
