[0027] The working principle of the present invention is as follows:

[0028] In this design, the reagent and the reagent testing mechanism thereof; the reagent is arranged in the reagent testing mechanism, and is used to detect indoor formaldehyde. The column body 2 in this design is in the shape of a square cylinder, and the horizontal cross section is a square.

[0029] In the present design, the reagent testing mechanism comprises a column body 2, a circular cylinder 1 is arranged at the top of the column body 2, and a base 10 is arranged at the bottom of the column body 2, forming a three-section structure.

[0030] In this design, a middle partition is provided in the middle of the column body 2, which is divided into a left chamber and a right chamber; in this design, the top surface of the left chamber is open and communicated with the left bin 101; a suction fan 4 is provided at the lower part of the left side surface of the left chamber. When in use, the suction fan 4 is controlled by the PLC controller to suck in the air containing formaldehyde in the room, and then the semicircular cover plate rotating member 5 is controlled by the PLC controller to work.

[0031] The semicircular cover plate rotating component 5 includes a convex shaft 52 installed in the middle of the top surface of the middle partition plate 1 in the circular cylinder 1, a sleeve is sleeved on the convex shaft 52, a reduction motor 51 is installed on the top of the convex shaft 52, the shaft of the reduction motor 51 is connected to the sleeve, and the sleeve is connected to the semicircular cover plate 53; a position sensor transmitter 54 is arranged at the bottom of the left end of the semicircular cover plate 53; a position sensor receiver 55 is arranged at the rear end of the top surface of the middle partition plate 1. Among them, the semicircular cover plate 53 is made of transparent plastic or transparent glass. When in use, the reduction motor 51 works, driving the sleeve to be placed on the convex shaft 52, and the sleeve drives the semicircular cover plate 53 linked thereto to rotate. When the position sensor transmitter 54 on the semicircular cover plate 53 senses the position sensor receiver 55, a signal is sent to the PLC controller, and the PLC controller controls the reduction motor 51 to stop working. The semicircular cover plate 53 is covered on the top surface of the left chamber 101 of the circular cylinder 1, so that the left chamber 101 of the circular cylinder 1 and the left chamber of the column cylinder 2 form a closed space to form a formaldehyde identification chamber.

[0032] In this design, the top surface of the right chamber of the column body 2 is provided with a central through hole, and the upper part of the right chamber is provided with a grid plate 72, which divides the right chamber into a right upper chamber and a right middle chamber; a cover door 73 is provided in front of the upper right chamber; a sealing ring is provided on the inner wall of the cover door 73; an inclined plate 71 is provided in the right middle chamber, and a discharge port is provided at the left bottom of the right middle chamber. When in use, the cover door 73 is opened, and the reagent bag is placed on the grid plate 72 of the upper right chamber. A hole is also provided in the middle of the grid plate 72, which corresponds to the central through hole on the top surface of the right chamber.

[0033] When in use, a PLC controller is used to control the operation of the servo motor 61. The servo motor 61 controls the rotation of the turntable 64 through a belt. The rotation of the turntable 64 drives the screw rod 65 to move up and down. The screw rod 65 moves downward, and the tip of the bottom end of the screw rod passes through the central through hole on the top surface of the right chamber to the reagent bag on the grid plate 72 of the upper right chamber. After the reagent bag is punctured, the reagent in the reagent bag falls into the right middle chamber through the grid plate. An inclined plate 71 is provided in the right middle chamber, which is guided to the bottom of the left chamber through the discharge port.

[0034] Then, the PLC controller controls the electromagnetic valve 2 31 to introduce the purified water in the clean water tank 3 on the upper left side of the left chamber into the left chamber; the servo motor 3 14 drives the stirring paddle to stir and dilute the reagent in the reagent bag to form a reagent solution. A time relay is installed on the circuit board of the PLC controller, so that the length of time can be controlled. The control circuit involved is the prior art.

[0035] Then, the micro electromagnetic valve of the developer bin 13 is controlled to open by the PLC controller, and the developer is introduced into the reagent solution by the dropper 131, so as to measure the formaldehyde content of the indoor gas. The reagent solution after the test is photographed by the camera 12, and the picture parameters are sent to the PLC controller. The PLC controller compares the detected picture with the color pictures containing different content of formaldehyde in the picture database in the PLC controller, and finally obtains the detection data of the formaldehyde content, which is displayed on the display 8 in front of the lower right chamber of the column body 2. Of course, a wireless module can also be installed on the circuit board, and the wireless signal can be directly sent to the remote control connected to the design, or the signal can be sent to the user's smart phone.

[0036] The above description is only a preferred embodiment of the present invention, so all equivalent changes or modifications made according to the features and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
