A portable formaldehyde sample processing cover is shown in figure 1, and comprises a transparent cover 1, wherein the transparent cover 1 is made of foldable materials convenient for carrying, an air hole 11 is formed in the top of the transparent cover 1, a replaceable filter 12 is installed on the air hole 11, and in the embodiment, the filter 12 is a HEPA filter or an activated carbon adsorption sheet. In order to further improve the purification effect, the transparent cover 1 is detachably connected with a shell 13, one side inside the shell 13 is provided with an air inlet unit 2 communicated with the air hole 11, one side of the shell 13, opposite to the air inlet unit 2, is provided with a blower unit 3, and a purification chamber 4 is arranged between the air inlet unit 2 and the blower unit 3. Therefore, under the general condition, the transparent cover 1 provides a safe operation environment to reduce the damage of the formaldehyde solution, and has the advantages of portability and indoor and outdoor universality; when required, the components such as the shell 13 can be installed, and then the air in the transparent cover 1 is sucked from the air hole 11, and is transversely transmitted under the cooperation of the air inlet unit 2 and the air blower unit 3, and is discharged after being adsorbed and filtered by the purifying chamber 4, so that the environment-friendly air conditioner is green and environment-friendly.

As shown in fig. 1, the air inlet set 2 includes a driving motor 21 located in the air inlet set chamber, an output shaft of the driving motor 21 is connected with a centrifugal rotor 22 arranged towards the purifying chamber 4, a filter element 23 is arranged through the center of the centrifugal rotor 22, correspondingly, the air blower set 3 has the same internal structure as the air inlet set 2, but the centrifugal rotor 22 faces towards the purifying chamber 4, namely, the output shaft ends of the two driving motors 21 are oppositely arranged, and the two centrifugal rotors 22 are inclined in the same direction when viewed from one driving motor 21 to the other end, so that the driving motors 21 of the air blower set 2 are turned on to enable the centrifugal rotors 22 to rotate to form suction force, air in the transparent cover 1 can be sucked into the air holes 11 along the direction of the centrifugal rotors 22, and after the decomposed defense line is filtered and absorbed by a first channel of the filter element 23, the driving motors 21 of the air blower set 3 are turned on simultaneously to enable the centrifugal rotors 22 to face towards the same direction, The same rotational speed is rotatory, and this process can form the negative pressure because wind channel cavity, and centrifugal airflow can get into clean room 4 constantly, can fully contact with inside absorption filler after getting into clean room 4 to guarantee good purifying effect.

As shown in fig. 1, the clean room 4 includes spoilers 41 disposed at intervals in a staggered manner, and the absorbing members 42 are disposed between the spoilers 41, and the absorbing members 42 are made of apatite-coated titanium dioxide nano-photocatalyst. Therefore, the centrifugal air flow is continuously introduced into the purification chamber 4 through the air duct, and is conducted by the spoiler 41 to be in full contact with the adsorbing member 42, thereby realizing multiple purification, decomposition and filtration.

As shown in fig. 1, the spoiler 41 is arranged obliquely in the direction of the blower unit 3, so that the air to be cleaned can flow in the direction of the spoiler 41. In addition, at least one pair of spoilers 41 are respectively arranged on the upper and lower staggered spoilers, so that when the number of the spoilers 41 which are staggered is increased, the advancing direction of the centrifugal airflow can be changed for many times, the contact area between the air and the adsorption element 42 is increased, and the purification effect is greatly improved. In this embodiment of the invention, the confined space is defined by two baffles 41 staggered at the top of the clean room 4 and two baffles 41 staggered at the bottom of the clean room 4.

As shown in figure 1, a formaldehyde sensor 5 is arranged in the transparent cover 1, and the formaldehyde sensor 5 is in communication connection with the air inlet unit 2 and the controller of the air supply unit 3 and can be automatically started according to the formaldehyde concentration in the transparent cover 1.

The working principle of the portable formaldehyde sample treatment cover is as follows: in general, the transparent cover 1 provides a safe operation environment, and the filter 12 realizes a purifying and adsorbing effect; when needed, the components such as the shell 13 are installed, and then the formaldehyde sensor 5 monitors, the driving motor 21 of the air inlet fan unit 2 is automatically started according to the concentration of formaldehyde in the transparent cover 1, so that the centrifugal rotor 22 rotates to form suction, air can be sucked into the air holes 11 along the tangential direction of the centrifugal rotor 22, after the first filtering and absorbing defense line of the filter element 23, the driving motor 21 of the air supply unit 3 is simultaneously started, so that the centrifugal rotor 22 rotates towards the same direction and at the same rotating speed, in the process, negative pressure can be formed due to the hollow air channel, centrifugal airflow can be ensured to continuously enter the purifying chamber 4, and then the centrifugal airflow is guided by the spoiler 41 to be transmitted, so that the centrifugal airflow is fully contacted with the adsorption element 42, and multiple times of purification, decomposition and filtration are realized.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
