The detection device for implementing the formaldehyde removal rate of the utility model, has the advantages that：Use the utility model
Formaldehyde removal rate detection device when, case lid can be covered in the opening of chamber, until case lid bottom surface and cyclic annular block
Portion abuts, at this point, first annular magnetic stripe and the second annular magnetic stripe magnetism are attracting, can prevent case lid from loosening, be set in case lid lid
When at aperture position, the sealing rubber strip being located on case lid side wall is abutted with opening inner side wall, forms sealing.In experimentation
In, using syringe by trace formaldehyde solution by the way that in micro-injection hole injection testing case, formalin is coated on " ︺ " shape sample
Then the surface of product frame starts fan, promote formalin volatilization, after completion to be evaporated, detected just by formaldehyde tester
Beginning content of formaldehyde numerical value.After primary detection completion, fan is closed, opens ultraviolet lamp tube, the formaldehyde that removes of photocatalyst is accelerated to imitate
Fruit.After some time, content of formaldehyde numerical value is detected again, is removed rate calculating.It, can by using the chamber of sealing
It avoids external environment from interfering test, improves test accuracy rate.
Description of the drawings
Below in conjunction with accompanying drawings and embodiments, the utility model is described in further detail, in attached drawing：
Fig. 1 is the decomposition texture schematic diagram of the detection device of the utility model formaldehyde removal rate.
Specific implementation mode
It is new to this practicality below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer
Type embodiment is described in further detail.
As shown in Figure 1, in the detection device first embodiment of the formaldehyde removal rate of the utility model, the detection device 1
