Description

Technical Field

[0001] This utility model relates to the field of rapid formaldehyde detection technology, specifically a portable rapid formaldehyde detection kit. Background Technology

[0002] A formaldehyde rapid test kit is a simple chemical reagent tool used to quickly detect the concentration of formaldehyde in the air. Its core function is to achieve semi-quantitative analysis of formaldehyde through a chemical colorimetric reaction, helping users to initially determine whether there is a risk of excessive formaldehyde levels in the environment. The formaldehyde rapid test kit is a portable detection tool based on a chemical colorimetric reaction. Users expose the reagent to the air to be tested, where formaldehyde reacts with a specific chemical reagent to generate a colored compound. The formaldehyde concentration is then estimated by comparing the color intensity using a colorimetric card. It is simple to operate, inexpensive, and suitable for rapid screening in non-professional settings such as homes and offices.

[0003] In existing technologies, such as the rapid formaldehyde detection device for textiles and wood disclosed in CN209559853U, there is an insulated housing and a formaldehyde detector with a detection probe. The formaldehyde detector is located inside the insulated housing, which contains a removable container with a heating chamber. The heating chamber and the insulated housing form a closed space. The device heats the heating chamber, raising the temperature of the sample and accelerating the molecular motion within it. Volatile components are dispersed through an escaping channel to the detection probe of the formaldehyde detector. Thus, the rapid formaldehyde detection device for textiles and wood can quickly and sensitively detect the presence of formaldehyde in the sample.

[0004] Existing methods use heating devices to heat the heating chamber, raising the temperature of the sample and accelerating the molecular motion within it, thus enabling rapid and sensitive detection of formaldehyde. However, these methods have limited applications and require specially trained professionals to operate, failing to meet the needs for rapid on-site formaldehyde content detection. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Given that the existing technologies mentioned above have limited application scenarios and require specially trained professional technicians to operate, they cannot meet the needs for rapid on-site formaldehyde content testing.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A portable formaldehyde rapid detection kit includes a detection kit body, wherein the interior of the detection kit body is provided with a detection component for formaldehyde detection, and the upper end of the detection component is provided with a limiting component for limiting position. The detection component includes a storage unit installed inside the detection box. The storage unit has a first storage cavity inside, and a second storage cavity is provided on the right side of the first storage cavity inside the storage unit. A color development box is placed inside the first storage cavity.

[0008] As a further embodiment of this utility model: a reagent pack is placed inside the second storage cavity, and connectors are fixed at both ends of the storage component.

[0009] As a further improvement of this utility model, one side of the connector is slidably connected to a slot formed in the inner wall of the detection box.

[0010] As a further embodiment of this utility model: the limiting component includes a limiting magnetic hole, the limiting magnetic hole is opened on the upper surface of the storage component, and a limiting magnet is movably connected inside the limiting magnetic hole.

[0011] As a further improvement of this utility model, the limiting magnet is externally connected to a mounting groove formed on the detection box.

[0012] As a further improvement of this utility model: the upper surface of the limiting magnet is fixed with a movable block that is movably connected to the detection box.

[0013] As a further embodiment of this utility model: one end of the storage component is fixed with a connecting block, and the end of the connecting block is movably connected to an elastic self-locking device fixed inside the detection box.

[0014] As a further improvement of this utility model: a color scale card is fixed on the upper surface of the detection box, and a placement groove is provided on the inner wall of the color scale card.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model involves taking out the color developing box and placing it into the placement slot to limit its position. Then, a reagent pack is poured into the color developing box. The phenol reagent in the reagent pack reacts chemically with formaldehyde in the air to generate a compound. This compound will show different colors under specific conditions. By comparing with a standard color scale card, the concentration range of formaldehyde in the air can be roughly determined, making it convenient for carrying and use.

[0016] 2. This utility model allows the storage component to be manually pressed, causing the connecting block to engage with the elastic self-locking device to limit the storage component. The limiting magnet is then inserted into the limiting magnetic hole to further secure the storage component, effectively reducing the possibility of accidental opening. Attached Figure Description

[0019] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0022] Example 1 Please see Figures 1-5 This is the first embodiment of the present utility model. This embodiment provides a portable formaldehyde rapid detection kit, including a detection kit body 1. The inside of the detection kit body 1 is provided with a detection component for formaldehyde detection, and the upper end of the detection component is provided with a limiting component for limiting. The detection component includes a storage unit 2, which is installed inside the detection box 1. The storage unit 2 has a first storage cavity 21 inside, and a second storage cavity 22 is provided on the right side of the first storage cavity 21 inside the storage unit 2. A color development box 23 is placed inside the first storage cavity 21.

[0023] Specifically, the second storage cavity 22 contains a reagent pack 24, and both ends of the storage component 2 are fixed with connectors 25.

[0024] Furthermore, the first storage chamber 21 and the second storage chamber 22 respectively store the color development box 23 and the reagent pack 24, which facilitates the formaldehyde detection operation.

[0025] Specifically, one side of the connector 25 is slidably connected to a slot 26 formed on the inner wall of the detection box 1.

[0026] Furthermore, by detecting the slot 26 set inside the housing 1, it can play a guiding role with the cooperation of the connector 25.

[0027] In use, place the detection box 1 in a suitable position and manually press the storage component 2 to separate the storage component 2 from the connecting block 4 and the elastic self-locking device 5. At the same time, the elastic self-locking device 5 pushes the storage component 2, causing one end of the storage component 2 to move out of the detection box 1. The slot 26 set in the detection box 1, with the cooperation of the connecting component 25, can play a guiding role, facilitating the movement of the storage component 2. The storage component 2 has a first storage cavity 21 and a second storage cavity 22, which respectively store a color developing box 23 and a reagent pack 24. First, take out the color developing box 23 and place it in the placement slot 7 to limit the position of the color developing box 23. Then, take out a reagent pack 24 and pour it into the color developing box 23. The phenol reagent in the reagent pack 24 reacts chemically with the formaldehyde in the air to generate a compound. This compound will show different colors under specific conditions. By comparing with the standard color scale card 6, the concentration range of formaldehyde in the air can be roughly determined, which is convenient for use.

[0028] In summary, when using this portable formaldehyde rapid detection kit, the color development box 23 is taken out and placed into the placement slot 7, which then limits the position of the color development box 23. A reagent packet 24 is then taken out and poured into the color development box 23. The phenol reagent in the reagent packet 24 reacts chemically with the formaldehyde in the air to generate a compound. This compound will show different colors under specific conditions. By comparing with the standard color scale card 6, the concentration range of formaldehyde in the air can be roughly determined, making it convenient to use.

[0029] Example 2 Please see Figures 1-5 This is the second embodiment of the present utility model.

[0030] Specifically, the limiting component includes a limiting magnetic hole 3, which is opened on the upper surface of the storage component 2. A limiting magnet 31 is movably connected inside the limiting magnetic hole 3, and a mounting groove 32 opened on the detection box 1 is movably connected outside the limiting magnet 31. A movable block 33 that is movably connected to the detection box 1 is fixed on the upper surface of the limiting magnet 31.

[0031] Furthermore, the limiting magnet 31 is pulled out from the mounting groove 32, so that the limiting magnet 31 is separated from the limiting magnetic hole 3, thereby releasing the limitation on the storage component 2.

[0032] Specifically, a connecting block 4 is fixed to one end of the storage component 2, and an elastic self-locking device 5 fixed inside the detection box 1 is movably connected to the end of the connecting block 4. A color scale card 6 is fixed to the upper surface of the detection box 1, and a placement groove 7 is opened on the inner wall of the color scale card 6.

[0033] Furthermore, the color developing box 23 is removed and placed into the placement slot 7, thereby limiting the position of the color developing box 23.

[0034] In use, by detecting the movable block 33 on the box 1, first manually pull the movable block 33 to pull the limiting magnet 31 out of the mounting slot 32, so that the limiting magnet 31 separates from the limiting magnetic hole 3, thereby releasing the limitation on the storage component 2. After use, the storage component 2 can be manually pressed to make the connecting block 4 engage with the elastic self-locking device 5 to limit the storage component 2, and the limiting magnet 31 is inserted into the limiting magnetic hole 3 to further fix the storage component 2, effectively reducing the possibility of accidental opening.

[0035] In summary, when using this portable formaldehyde rapid detection kit, the color development box 23 is taken out and placed into the placement slot 7 to limit its position. A reagent packet 24 is then poured into the color development box 23. The phenol reagent in the reagent packet 24 reacts chemically with the formaldehyde in the air to generate a compound. This compound will show different colors under specific conditions. By comparing with the standard color scale card 6, the concentration range of formaldehyde in the air can be roughly determined, making it easy to use. Furthermore, the limiting magnet 31 is inserted into the limiting magnetic hole 3 to further fix the storage component 2, effectively reducing the possibility of accidental opening.
