[0029] Embodiment:

[0030] Refer to Figures 1 - 6 , an embodiment of the present utility model provides a sample placing device for a formaldehyde demonstration box, including a box door 2 with a sealing sleeve 3 installed at the bottom and a formaldehyde demonstration box main body 1. The box door 2 is clamped to the top of the formaldehyde demonstration box main body 1 through the sealing sleeve 3. The sealing sleeve 3 is made of rubber. A board is placed in the formaldehyde demonstration box main body 1 for releasing formaldehyde. A timer and a formaldehyde detector are installed in the formaldehyde demonstration box main body 1 for setting the time and detecting the formaldehyde concentration in the formaldehyde demonstration box main body 1. It further includes: a storage shell 4 fixedly connected to the box door 2. Among them, a valve 5 is installed at the bottom end of the storage shell 4, and an elastic member is arranged on the storage shell 4. The valve 5 is pressed tightly against the bottom end of the storage shell 4 by the elastic force of the elastic member; a connecting shell 6 is detachably installed at the top end of the storage shell 4. Among them, an extrusion part is arranged at the top of the connecting shell 6, and the extrusion part is used to flip the valve 5.

[0031] Specifically, during use, through the settings of the extrusion part and the elastic member, it is possible to facilitate the flipping open and reset closing of the valve 5 at the bottom of the storage shell 4. After the formaldehyde in the formaldehyde demonstration box main body 1 normally rises to the target value and the box is kept airtight, the formaldehyde removal sample can be put into the formaldehyde demonstration box main body 1 without the operator opening the box door 2, greatly reducing the leakage of formaldehyde in the box to ensure the formaldehyde concentration in the box, thereby improving the formaldehyde removal demonstration effect of the formaldehyde removal sample.

[0032] The extrusion part includes a rubber airbag 7. The bottom end of the rubber airbag 7 is fixedly connected to the top end of the connecting shell 6. The top end of the rubber airbag 7 is fixedly connected to a pressing ball 8. The rubber airbag 7, the pressing ball 8, the connecting shell 6, and the storage shell 4 are interconnected.

[0033] Specifically, during use, by pressing the pressing ball 8 and the rubber airbag 7, the air pressure inside the connecting shell 6 and the storage shell 4 is increased. Under the action of the air pressure, it is convenient to flip open the valve 5 at the bottom of the storage shell 4, so that the formaldehyde removal sample stored in the storage shell 4 drops into the formaldehyde demonstration box main body 1.

[0034] The elastic member includes a bracket 51 fixedly connected to the storage shell 4. A straight rod 52 is fixedly connected to the bracket 51. Among them, a connecting rod 53 is rotatably connected to the straight rod 52. A torsion spring 54 is installed between the connecting rod 53 and the straight rod 52. The valve 5 is fixedly connected to the connecting rod 53.

[0035] Specifically, during use, when the valve 5 is flipped open under the action of air pressure, it drives the connecting rod 53 to rotate, and at the same time twists and compresses the torsion spring 54. When the pressing ball 8 is released, under the elastic force of the torsion spring 54, the valve 5 can quickly flip back to its original position and closely adhere to the port of the storage shell 4.

[0036] A plurality of anti-slip strips 9 are fixedly connected to the connecting shell 6. The plurality of anti-slip strips 9 are annularly distributed on the surface of the connecting shell 6. The number of anti-slip strips 9 is preferably 15.

[0037] Specifically, through the setting of the anti-slip strips 9, the friction on the surface of the connecting shell 6 can be increased, which is convenient for applying force to rotate the connecting shell 6.

[0038] A reinforcing sleeve 55 is fixedly connected to the connecting rod 53. One end of the reinforcing sleeve 55 is fixedly connected to the surface of the valve 5.

[0039] Specifically, through the setting of the reinforcing sleeve 55, the valve 5 can be reinforced, so that the connection between the valve 5 and the connecting rod 53 is more firm.

[0040] A sealing ring 41 is fixedly sleeved on the storage shell 4. The top end of the sealing ring 41 is fixedly connected to the bottom of the box door 2. The material of the sealing ring 41 is rubber.

[0041] Specifically, through the setting of the sealing ring 41, the sealing performance at the connection between the storage shell 4 and the box door 2 can be improved, preventing formaldehyde in the formaldehyde demonstration box main body 1 from leaking.

[0042] The bottom end of the connecting shell 6 is fixedly connected with a threaded pipe 61. The threaded pipe 61 is threadedly connected to the storage shell 4.

[0043] Specifically, through the setting of the threaded pipe 61, it is convenient to quickly disassemble and assemble the connecting shell 6, so as to facilitate the operator to put the formaldehyde removal sample into the storage shell 4.

[0044] A sealing pad 42 is fixedly connected to the top end of the storage shell 4. When the connecting shell 6 is connected to the storage shell 4, the bottom end of the connecting shell 6 is in contact with the sealing pad 42. The material of the sealing pad 42 is rubber.

[0045] Specifically, by setting the gasket 42, the sealing performance at the connection between the storage case 4 and the connection case 6 can be improved, further preventing the leakage of formaldehyde inside the formaldehyde demonstration box body 1.

[0046] On both sides of the top of the box door 2, handles 10 are fixedly installed, and the two handles 10 are symmetrically arranged.

[0047] Specifically, by setting the handles 10, it is convenient for the operator to apply force to take the box door 2.

[0048] An observation window 11 is provided on the formaldehyde demonstration box body 1, and the material of the observation window 11 is tempered glass.

[0049] Specifically, by setting the observation window 11, it is convenient to directly observe the demonstration situation inside the formaldehyde demonstration box body 1.

[0050] During the use of the sample placing device for the formaldehyde demonstration box, first, the formaldehyde removal sample is placed into the storage case 4, and then the connection case 6 is installed on the storage case 4. When the formaldehyde concentration in the formaldehyde demonstration box body 1 rises to the target value, by squeezing the pressing ball 8 and the rubber airbag 7, the air pressure inside the connection case 6 and the storage case 4 is increased. Under the action of the air pressure, it is convenient to turn and open the valve 5 at the bottom of the storage case 4, so that the formaldehyde removal sample stored in the storage case 4 drops into the formaldehyde demonstration box body 1;

[0051] At the same time, when the valve 5 is turned and opened, the connecting rod 53 is driven to rotate, and the torsion spring 54 is torsionally compressed at the same time. When the pressing ball 8 is released, under the elastic force of the torsion spring 54, the valve 5 can quickly turn back to its original position and closely adhere to the port of the storage case 4.

[0052] During the use of this device, through the coordinated use of the rubber airbag 7, the pressing ball 8, the storage case 4, the valve 5, and the torsion spring 54, after the formaldehyde in the formaldehyde demonstration box body 1 normally rises to the target value and the box is kept airtight, the formaldehyde removal sample can be put into the formaldehyde demonstration box body 1 without the operator opening the box door 2, greatly reducing the leakage of formaldehyde inside the box to ensure the formaldehyde concentration inside the box, thereby improving the formaldehyde removal demonstration effect of the formaldehyde removal sample.

[0053] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
