[0028] In the utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "connection", "fixing" and the like should be understood broadly, for example, it can be fixedly connected, can be detachably connected, or integrated;It can be directly connected, or indirectly connected through an intermediate medium, it can be the communication inside two elements or the interaction relationship of two elements.But it is noted that direct connection means that the connection between the two main bodies does not pass through the connection relationship between the structures, but only through the connection structure to form an integral whole.For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0029] In the present application, unless otherwise explicitly specified and limited, the first feature is "on" or "under" the second feature, which can be direct contact between the first and second features, or indirect contact between the first and second features through an intermediate medium. In the description of the present application, the description of the terms "one embodiment", "some embodiments", "example", "specific example" or "some examples" means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application. In the present application, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0030] In the present application, as shown in Figures 1-6 , a kind of peroxoacetic acid aqueous solution online detection device is provided, including shell 1 and detection head 2, the end of the shell 1 away from the detection head 2 is equipped with signal transmission piece 3, the detection head 2 can be connected at the bottom of the shell 1, and the detection head 2 and the bottom of the shell 1 can be electrically connected, the detection device further includes: upper installation part 4, the upper installation part 4 is installed in the upper section of the shell 1;Lower installation cylinder 5, the bottom of the lower installation cylinder 5 is sealingly connected with the detection head 2, and the top is detachably connected in the upper installation part 4, the part of the shell 1 below the upper installation part 4 can be inserted into the lower installation cylinder 5.

[0031] The detection device of the present application is used, as Figures 1 to 6 , the lower installation cylinder 5 is sleeved on the outside of the shell 1, and the lower detection head 2 and the bottom of the shell 1 reach the installation position (realize electric connection), realize the stable connection of the lower installation cylinder 5 and the shell 1 after the upper installation part 4 is connected with the lower installation cylinder 5, at this time, the upper section of the shell 1 can be held to insert the detection head 2 position into solution for detection. The lower installation cylinder 5 and the detection head 2 are combined into one body in the present application, when continuous detection is required, the used lower installation cylinder 5 and detection head 2 can be separated from the shell 1 as a whole, and new lower installation cylinder 5 and detection head 2 can be installed, without cleaning the shell 1 and the newly installed detection and lower installation cylinder 5. Compared with the existing detection device, the cleaning and drying procedures of the connection position of the shell 1 and the detection head 2 are removed, and the influence of the sealing ring structure in the cleaning process of this area is also reduced. Moreover, the connection between the detection head 2 and the shell 1 is changed from the existing direct connection to the indirect connection through the lower installation cylinder 5, which adjusts the actual fixing position of the detection head 2. When the detection is completed and the replacement is disassembled, the hand operation position of the operator does not contact the position of the lower installation cylinder 5 contacting the solution, which reduces the possibility of the operator's hand contacting the residual solution.

[0032] The utility model discloses an improved detection device, which is improved on the basis of the existing typical detection device, and the cost of re-designing and opening mould for the structure of the casing 1 and the detection head 2 is reduced.

[0034] In the preferred embodiment, the upper mounting part 4 comprises an upper mounting ring 401. As shown in the drawings, the annular upper mounting part 4 is fixed to the casing 1, so that the upper mounting part 4 can be conveniently fixed to the upper section of the casing 1.

[0035] In the alternative embodiment, other forms of the upper mounting part 4 can also be used, such as a vertical bar-shaped upper mounting part 4.

[0036] It should be noted that the improvement of the utility model lies in the detection head mounting structure of the detection device, and the data processing module and the display module of the man-machine interaction of the detection device are not limited or improved. The person skilled in the art can flexibly select the existing structure during implementation.

[0037] In the preferred embodiment, the upper mounting ring 401 is bonded to the casing 1.

[0038] Alternatively, the upper mounting ring 401 can also be fixed to the casing by a hoop.

[0039] In the Figure 1 In the preferred embodiment, the inner side of the lower mounting cylinder 5 is provided with a silica gel sleeve 6, the casing 1 is formed with a fixing ring 402, the silica gel sleeve 6 can be interference-fitted on the fixing ring 402, and the silica gel sleeve 6 and the casing 1 are provided with an air gap 7.

[0040] As Figures 1 to 2As shown, when the lower mounting cylinder 5 is disassembled and mounted again, the air gap 7 is used to balance the air pressure between the casing 1 and the lower mounting cylinder 5, and after the silica gel sleeve 6 is interference fitted on the fixing ring 402, the lower mounting cylinder 5 can be stably mounted. By such arrangement, the mounting of the lower mounting cylinder 5 can be realized by a relatively simple connecting structure, facilitating processing and operation. Moreover, the silica gel sleeve 6 can also play a sealing role to prevent the solution from entering the inside of the lower mounting cylinder 5 when the upper mounting part 4 is mistakenly touched.

[0043] For the connecting mode of the lower mounting cylinder 5 and the upper mounting part 4, in alternative embodiments, it can also be arranged as shown in Figure 5 As shown, the upper mounting ring 401 and the lower mounting cylinder 5 are connected by magnetic attraction. Specifically, a magnetic ring 15 can be added to the outer edge of the top of the lower mounting cylinder 5, and the upper mounting part 4 is provided with a connecting part that magnetically attracts the lower magnetic ring 15.

[0046] In Figure 1In the shown embodiment, for the bonding mode between the detection head 2 and the lower mounting cylinder 5, further specifically, the lower end of the mounting cylinder is provided with a first ring rib 9 and a second ring rib 10 in an upper-to-lower direction, a sealing groove 11 is arranged between the first ring rib 9 and the second ring rib 10, and the inner edge of the first ring rib 9 is projected on the inner side of the second ring rib 10 in the vertical direction; the edge of the top of the detection head 2 is abutted against the first ring rib 9; and the sealing groove 11 is filled with sealing glue 12.

In this way, the detection head 2 can be bonded and fixed by the sealing glue 12, and the sealing between the detection head 2 and the first ring rib 9 and the second ring rib 10 is realized. Figure 5

[0048] For the connection mode between the mounting cylinder and the detection head 2, in an alternative embodiment, as shown in Figure 6 the lower mounting cylinder 5 and the detection head 2 are connected by screwing.
