Description

Technical Field

[0001] This utility model relates to a wall-mounted formaldehyde real-time monitoring device, belonging to the technical field of monitoring devices. Background Technology

[0002] Formaldehyde, also known as methanal, is a colorless gas with a pungent odor that irritates the eyes and nose. It is a colorless liquid with a pungent odor. Formaldehyde can be produced by dehydrogenation or oxidation of methanol under the catalysis of metals such as silver and copper, or it can be separated from the oxidation products of hydrocarbons. It is used as a pesticide and disinfectant, and as a raw material for the production of phenolic resin, urea-formaldehyde resin, vinylon, hexamethylenetetramine, pentaerythritol, and dyes.

[0003] Chinese Patent Publication No. (CN 207232120 U) discloses an indoor formaldehyde monitoring device, including a first mounting base with mounting grooves on both sides. A second mounting base is installed inside the two mounting grooves. Sliding plates are provided at the connection points between the second mounting bases and the two mounting grooves on both sides. A through-type sliding track is provided at the top of each of the two mounting grooves. A sliding block is installed inside the sliding track. A sliding push button is provided on the top of the sliding block extending into the mounting groove and fixedly connected to the sliding plate. A first placement groove is provided at the top of the first mounting base, and a second placement groove is provided at the top of the second mounting base. A first rotating shaft is provided on one side of the interior of the first placement groove. This invention has a simple overall structure and effectively prevents the formaldehyde monitor from accumulating dust due to prolonged exposure to air, keeping the formaldehyde monitor clean and making it more convenient to use.

[0004] After interior decoration, monitoring devices are used to monitor indoor formaldehyde levels. Traditional monitoring devices are usually hung on the wall surface, but formaldehyde usually floats up and down in the air. The installation position of the monitoring device in the above-mentioned device is relatively fixed, so it is impossible to monitor formaldehyde at different heights. This may lead to a deviation between the detected formaldehyde level and the actual level, making it inconvenient for operators to use.

[0005] Therefore, a wall-mounted formaldehyde real-time monitoring device is proposed. Utility Model Content

Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] Example 1

[0029] like Figure 1-5As shown, this utility model embodiment provides a wall-mounted formaldehyde real-time monitoring device, including a housing 1. An L-shaped plate 3 is provided on the front side of the housing 1, and a formaldehyde detector 4 is provided on the surface of the L-shaped plate 3. An adjustment mechanism 2 is provided on the surface of the housing 1. The adjustment mechanism 2 includes a motor 201 and a first gear plate 203. The motor 201 is located at the top of the housing 1. The first gear plate 203 is located on the left side of the inner cavity of the housing 1. A first gear 204 is movably connected to the front side of the inner cavity of the housing 1. A second gear 205 is movably connected to the front side of the inner cavity of the housing 1. The surface of the second gear 205 meshes with the surface of a slide rod 206. The surface of the first gear plate 203 meshes with the surface of the first gear 204. A slide rod 206 is fixedly installed on the right side of the inner cavity of the housing 1. A second gear plate 207 is slidably connected to the surface of the slide rod 206. The surface of the second gear plate 207 meshes with the surface of the second gear 205. Connecting rods 208 are fixedly installed on the front sides of plate 207 and the first toothed plate 203. The other ends of the two connecting rods 208 are fixedly installed on the left and right sides of the rear side of L-shaped plate 3. Motor 201 is fixedly installed on the left side of the top of housing 1. The output end of motor 201 is fixedly connected to lead screw 202. The first toothed plate 203 is threaded to the surface of lead screw 202. A moving groove 209 is opened on the front side of housing 1. The rear side of L-shaped plate 3 is slidably connected to the inner cavity of moving groove 209. Sliding grooves 210 are opened on the left and right sides of housing 1. The two connecting rods 208 pass through the inner cavities of the two sliding grooves 210 and extend to the front side of housing 1. A sliding groove 211 is opened on the right side of the inner cavity of housing 1. The right side of the second toothed plate 207 is slidably connected to the inner cavity of sliding groove 211. A limiting groove 212 is opened on the left side of the inner cavity of housing 1. The left side of the first toothed plate 203 is slidably connected to the inner cavity of limiting groove 212.

[0030] By setting up the adjustment mechanism 2, the output of the motor 201 causes the first toothed plate 203 to cooperate with the first gear 204, the second gear 205, and the second toothed plate 207. The connecting rod 208 drives the L-shaped plate 3 and the formaldehyde detector 4 to move up and down synchronously, thereby enabling the formaldehyde detector 4 to monitor formaldehyde in the air at different heights. This improves the flexibility of equipment use and ensures the accuracy of formaldehyde monitoring. By setting up the moving groove 209, the movement of the L-shaped plate 3 can be limited to prevent it from shifting during movement, which could affect the formaldehyde level. The height adjustment of the formaldehyde monitor 4 is achieved by setting a sliding groove 210 to limit the direction of movement of the connecting rod 208, preventing it from deviating during movement and affecting the accuracy of the height adjustment of the formaldehyde monitor 4. The sliding groove 211 can limit the movement of the second toothed plate 207, preventing the direction of movement of the second toothed plate 207 from changing, thus affecting the adjustment of the position of the formaldehyde monitor 4. The limiting groove 212 can limit the movement of the first toothed plate 203, preventing the first toothed plate 203 from rotating synchronously with the lead screw 202.

[0031] Example 2

[0032] like Figure 1 As shown, in one embodiment, the formaldehyde monitor 4 is threaded with fixing bolts 5 around its surface, and the bottom of each of the four fixing bolts 5 is threaded to the inner surface of the L-shaped plate 3. Mounting plates 6 are fixedly installed on both the left and right sides of the housing 1, and mounting bolts 7 are threaded to the front of each of the four mounting plates 6.

[0033] This affects the adjustment of the position of the formaldehyde detector 4. By setting the fixing bolt 5, the formaldehyde detector 4 can be easily disassembled and assembled, making it convenient to maintain and repair the formaldehyde detector 4 after long-term use. By setting the mounting bolt 7, the device can be easily installed on the wall, making it convenient to install in different rooms according to usage needs.

[0034] When this utility model is in operation: First, the output of the motor 201 causes the lead screw 202 to drive the first toothed plate 203 to move. At this time, the first toothed plate 203 cooperates with the first gear 204. The first gear 204 rotates and drives the second gear 205 to rotate. At this time, the second gear 205 drives the second toothed plate 207 to move synchronously. The two connecting rods 208 move in the same direction, so that the L-shaped plate 3 drives the formaldehyde detector 4 to move, so that the formaldehyde detector 4 can monitor the formaldehyde in the air at different heights.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
