Description

Technical Field

[0001] The present application relates to the technical field of indoor detection equipment, and in particular to a quality detection device for indoor decoration. Background Art

[0002] During renovation, building materials such as plywood, paint, coatings, and carpets may release formaldehyde, making indoor formaldehyde pollution a common problem. Prolonged exposure to high concentrations of formaldehyde during renovation and living in the home can harm human health, thus requiring effective measures to detect and treat formaldehyde.

[0003] Currently, formaldehyde self-testing kits are commonly used to detect indoor formaldehyde levels during renovation and living in a new home. These kits are self-testing products that use color reactions to indicate formaldehyde levels, providing a rapid, semi-quantitative assessment of formaldehyde pollution. A formaldehyde self-testing kit includes an adsorbent, diluent, color developer, container, and color chart. In use, the adsorbent and diluent are first poured into the container, mixed thoroughly, and then placed indoors for 30 minutes. After standing, the color developer is poured into the container to allow the solution to develop color. The color is then compared to the color chart to determine the indoor formaldehyde level. However, in practice, this process involves tearing open the packaging of the adsorbent, diluent, and color developer sequentially, which is cumbersome and prone to spillage, potentially reducing the accuracy of the test.

[0049] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0050] like Figures 1 to 9 As shown, this application provides a quality testing device for interior decoration, including an operating table 1, a receiving box 2, a colorimetric plate 3, a stirring mechanism 4, and a feeding mechanism 5. The operating table 1 includes a table body 11 and a receiving cavity 12, with the receiving cavity 12 formed in the table body 11. The receiving box 2 is placed inside the receiving cavity 12. The colorimetric plate 3 is installed on the table body 11. The stirring mechanism 4 includes a cover plate 41 and a stirring assembly 42, with the cover plate 41 slidably covering the receiving box 2 along a first direction, and the stirring assembly 42 installed on the cover plate 41. The feeding mechanism 5 includes a feeding plate 51, at least one solvent connector 52, a powder connector 53, at least one solvent storage assembly 54, and a plurality of powder storage tubes 55. The feeding plate 51 is slidably mounted on the platform 11 along a second direction. At least one solvent connector 52 and powder connector 53 are both connected to the feeding plate 51. At least one solvent storage assembly 54 is detachably mounted on at least one solvent connector 52 and is arranged in a one-to-one correspondence with at least one solvent connector 52. It is also configured to feed solvent into the receiving box 2 after the solvent connector 52 moves along the second direction and aligns with the receiving box 2. The plurality of powder storage tubes 55 are all inserted into the powder connector 53 and are also configured to feed powder into the receiving box 2 after the powder connector 53 moves along the second direction and aligns with the receiving box 2.

[0051] It should be noted that the "above" and "below" directions refer to the bidirectional direction of the shortest line connecting the cover plate 41 and the receiving box 2, as detailed below. Figure 1 The X-axis is shown in the diagram. The second direction, above and below, refers to the bidirectional direction of the shortest line connecting the mixing assembly 42 and the feeding plate 51, as shown in the diagram. Figure 1 The Y-axis is shown in the figure.

[0052] It should also be noted that this embodiment uses two solvent connectors 52 as an example. Of course, in other embodiments, depending on the actual application requirements, the number of solvent connectors 52 can be one, three, four, etc., and is not limited here. Since the solvent storage components 54 and solvent connectors 52 are configured in a one-to-one correspondence, the number of solvent connectors 52 and the number of solvent storage components 54 are always equal. In this embodiment, one solvent storage component 54 is used to store the diluent, and the other solvent storage component 54 is used to store the color developer. The powder storage tube 55 is used to store the adsorbent.

[0053] The present application provides a quality inspection device for interior decoration. During use, the absorbent can be fed into the storage box 2 through the feeding plate 51, in cooperation with the powder connector 53 and the powder storage tube 55. The diluent and the color developer can be fed into the storage box 2 in cooperation with the solvent connector 52 and the solvent storage assembly 54. Compared with the related art, there is no need to tear the packaging of the absorbent, diluent and color developer, which effectively avoids the situation where the detection agent leaks due to tearing the packaging, and improves the convenience of use of the detection device. In addition, during use, the stirring assembly 42 can be used to stir the absorbent and the diluent so that the absorbent and the diluent are mixed evenly, which facilitates the absorbent to absorb formaldehyde and helps to improve the detection accuracy. The stirring assembly 42 can also be used to stir the color developer so that the color developer and the absorbent and the diluent are mixed evenly, which helps to improve the color development accuracy, thereby helping to reduce the colorimetric error in the colorimetric process, and further helps to improve the convenience of use of the detection device. In addition, during the stirring process, the cover plate 41 can cover the container 2 to prevent the absorbent, diluent, and color developer from splashing out of the container 2, thus avoiding the reduction of the detection reagent and affecting the detection accuracy, and also preventing the detection reagent from splashing onto the surface of the testing personnel. The container 2 is placed directly inside the platform 11, and after the test is completed, the testing personnel can directly remove the container 2 for cleaning, making it convenient to use.

[0054] In one embodiment of this application, please refer to Figures 1 to 9 The solvent connector 52 includes a mounting cylinder 521, a partition 522, a first solvent through-hole 523, a pointed cone 524, a solvent channel 525 and a plurality of second solvent through-holes 526. The mounting cylinder 521 is connected to the feed plate 51 and passes through the feed plate 51. The partition 522 is connected to the inner circumference of the mounting cylinder 521. The first solvent through-hole 523 is opened on the partition 522. The pointed cone 524 is connected to the side of the partition 522 facing away from the platform 11. The solvent channel 525 is opened on the pointed cone 524 and is connected to the first solvent through-hole 523. The plurality of second solvent through-holes 526 are all opened on the pointed cone 524 and are connected to the solvent channel 525 and are arranged at intervals.

[0055] The solvent storage assembly 54 includes a connecting cylinder 541, a storage cylinder 542, a sealing block 543 and a piston push rod 544. The connecting cylinder 541 is screwed to the inner circumference of the mounting cylinder 521 and is located on the side of the partition 522 facing away from the platform 11. The storage cylinder 542 is connected to the connecting cylinder 541 and communicates with the connecting cylinder 541. The sealing block 543 is sealingly installed at one end of the connecting cylinder 541 away from the storage cylinder 542 and is configured to be pierced by the pointed cone 524 after the connecting cylinder 541 is screwed to the mounting cylinder 521. The piston push rod 544 is sealingly installed in the storage cylinder 542 slidably along a first direction.

[0056] It should be noted that formaldehyde self-testing kits are currently typically disposable. During renovation and living in the property, multiple tests are usually required to monitor changes in indoor formaldehyde levels. Therefore, each test necessitates tearing open the packaging, significantly increasing the risk of leakage and making the process cumbersome.

[0057] With this configuration, the testing personnel can press the piston push rod 544 to expel the solvent in the storage cylinder 542 through the connecting cylinder 541, the second solvent through-hole 526, the solvent channel 525, the first solvent through-hole 523, and the mounting cylinder 521 into the receiving box 2. Compared to related technologies, there is no need to tear the packaging, effectively preventing solvent leakage, and it is convenient to use. Furthermore, since the connecting cylinder 541 is screwed to the mounting cylinder 521, the connecting cylinder 541 can be detached from the mounting cylinder 521. When the solvent in the storage cylinder 542 is exhausted, the testing personnel can replace it by disassembling the connecting cylinder 541. Compared to related technologies, when performing multiple tests indoors, there is no need to repeatedly tear the packaging, which also effectively prevents solvent leakage, and the easy replacement further improves the convenience of use. The combined action of the piston rod 544 and the sealing block 543 seals the solvent within the storage cylinder 542 and the connecting cylinder 541, preventing leakage and ensuring a good seal. After replacing the solvent storage assembly 54, the sealing block 543 can be pierced by the pointed cone 524, preventing it from interfering with solvent flow during testing.

[0058] Optionally, the storage cylinder 542 is made of a transparent material.

[0059] With this setup, testing personnel can directly observe changes in the solvent capacity inside storage cylinder 542 from the outside.

[0060] Optionally, the solvent storage assembly 54 also includes a scale line 545, which is located on the outer periphery of the storage cylinder 542.

[0061] With this configuration, when extruding the solvent, the tester can extrude the target volume of solvent through the scale line 545, which helps to improve the detection accuracy of the testing device.

[0062] In one embodiment of this application, please refer to Figures 1 to 9 The solvent connector 52 also includes a mounting bracket 527 and a sealing element 528. The mounting bracket 527 is connected to the inner circumferential side of the mounting cylinder 521 and is located on the side of the partition 522 facing the platform 11. The sealing element 528 is slidably mounted on the mounting bracket 527 along the first direction.

[0063] The sealing member 528 includes a sealing rod 5281, a sealing plate 5282 and a sealing elastic structure 5283. The sealing rod 5281 is slidably arranged on the mounting frame 527 along a first direction. The sealing plate 5282 is connected to one end of the sealing rod 5281 and is located between the partition 522 and the mounting frame 527. The sealing elastic structure 5283 is sleeved on the sealing rod 5281 and elastically supported between the mounting frame 527 and the sealing plate 5282.

[0064] With this arrangement, when the solvent does not need to be squeezed out, the sealing plate 5282 can be pressed against the partition 522 under the action of the sealing elastic structure 5283. The sealing plate 5282 can thus cover the first solvent through-hole 523, preventing solvent leakage and achieving a good sealing effect. Furthermore, the sealing elastic structure 5283 and the sealing plate 5282 can prevent the solvent from directly contacting the external environment and causing contamination of the solvent. When the solvent needs to be squeezed out, the inspector pushes the piston push rod 544, causing the pressure in the storage cylinder 542 to be greater than the elastic force of the sealing elastic structure 5283 on the sealing plate 5282, allowing the solvent to flow out of the storage cylinder 542.

[0065] Optionally, the sealing elastic structure 5283 is configured as a spring.

[0066] In one embodiment of this application, see [reference] Figures 1 to 9 The powder connector 53 includes a placement cylinder 531, a placement rack 532 and a cutting piece 533. The placement cylinder 531 is connected to the feed plate 51 and passes through the feed plate 51. The placement rack 532 is connected to the inner circumference of the placement cylinder 531 and is used to store multiple powder storage tubes 55. The cutting piece 533 is slidably installed on the outer circumference of the placement cylinder 531 along the third direction and is configured to cut the end of the powder storage tube 55.

[0067] It should be noted that the "above" and "below" directions refer to the bidirectional direction of the shortest line connecting the two ends of the placement cylinder 531, as detailed below. Figure 1 The Z-axis is shown in the figure.

[0068] This arrangement facilitates control of the amount of powder added during use through the powder storage tube 55, thereby improving detection accuracy. Furthermore, the cutting member 533 can be used to cut the end of the powder storage tube 55, thereby allowing powder to be removed from the powder storage tube 55. The placement rack 532 allows multiple powder storage tubes 55 to be placed within the placement barrel 531, facilitating cutting by the cutting member 533 and improving ease of use.

[0069] In one embodiment of this application, please refer to Figures 1 to 9 The powder connector 53 also includes a slide rail 534, which is connected to the outer periphery of the placement cylinder 531.

[0070] The cutting piece 533 includes a slider 5331, a mounting plate 5332, a pressing push rod 5333, a pressure block 5334, a cutting knife 5335 and a cutting elastic structure 5336. The slider 5331 is slidably connected to the slide rail 534 along the third direction, the mounting plate 5332 is mounted on the slider 5331, the pressing push rod 5333 is slidably passed through the mounting plate 5332 along the second direction, the pressure block 5334 is connected to the end of the pressing push rod 5333 away from the placement tube 531, and is located on the side of the mounting plate 5332 facing away from the placement tube 531. The cutting knife 5335 is installed at the end of the pressing push rod 5333 away from the pressure block 5334, and is located on the side of the mounting plate 5332 facing the placement tube 531. The cutting elastic structure 5336 is sleeved on the pressing push rod 5333 and elastically supported between the mounting plate 5332 and the pressure block 5334.

[0071] With this arrangement, during the cutting process, the cutting blade 5335 can be moved along the third direction via the slide rail 534 and the slider 5331, allowing the cutting blade 5335 to be used to cut any powder storage tube 55, providing ease of use. Furthermore, after the cutting blade 5335 has completed cutting, the cutting elastic structure 5336, through the pressing block 5334 and the push rod 5333, can drive the cutting blade 5335 back to its original position, facilitating the next use and thus improving user convenience.

[0072] Optionally, the cutting elastic structure 5336 is configured as a spring.

[0073] In one embodiment of this application, please refer to Figures 1 to 9 The powder connector 53 also includes an opening 535 and a filter screen 536. The opening 535 is located at one end of the placement cylinder 531 near the feeding plate 51, and the filter screen 536 is installed on the inner circumference of the placement cylinder 531 and extends to the outside of the placement cylinder 531 through the opening 535.

[0074] With this configuration, during the cutting process, the powder in the powder storage tube 55 falls into the receiving box 2 through the filter screen 536. The cutting waste from the powder storage tube 55 is filtered by the filter screen 536 and finally slides out of the placement cylinder 531 through the opening 535, preventing the cutting waste from the powder storage tube 55 from falling into the receiving box 2 and affecting the detection accuracy of the detection device.

[0075] In one embodiment of this application, see [reference] Figures 1 to 9The placement rack 532 includes a first placement plate 5321, a plurality of first through holes 5322, a second placement plate 5323, and a plurality of second through holes 5324. The first placement plate 5321 is connected to the inner circumference of the placement cylinder 531. The plurality of first through holes 5322 are all opened on the first placement plate 5321 and are spaced apart. The second placement plate 5323 is connected to the inner circumference of the placement cylinder 531 and is located on the side of the first placement plate 5321 facing the platform 11 and is spaced apart from the first placement plate 5321. The plurality of second through holes 5324 are all opened on the second placement plate 5323 and are spaced apart. The diameter of the first through hole 5322 is larger than the diameter of the second through hole 5324.

[0076] The powder storage tube 55 includes a first tube section 551 and a second tube section 552. The second tube section 552 is connected to the first tube section 551. The first tube section 551 passes through a first through hole 5322, and the second tube section 552 passes through a second through hole 5324. The diameter of the first tube section 551 is larger than the diameter of the second tube section 552.

[0077] With this configuration, since the diameter of the first through hole 5322 is larger than the diameter of the second through hole 5324, and the diameter of the first tube portion 551 is larger than the diameter of the second tube portion 552, the powder storage tube 55 and the placement rack 532 can be limited in the first direction, preventing the powder storage tube 55 from falling off the placement rack 532. Under the action of the first placement plate 5321 and the second placement plate 5323, the powder storage tube 55 can be limited in the second and third directions, so that the powder storage tube 55 is stably placed in the placement cylinder 531, which is convenient for the cutting blade 5335 to cut.

[0078] In one embodiment of this application, please refer to Figures 1 to 9 The container 2 includes a first container body 21, a second container body 22, a transport hole 23, and a guide surface 24. The second container body 22 is connected to the first container body 21. The transport hole 23 is opened between the first container body 21 and the second container body 22 and is used to connect the first container body 21 and the second container body 22. The guide surface 24 is opened in the second container body 22 and is used to guide the solution to the transport hole 23.

[0079] This configuration allows the second container 22 to receive solvents and powders during use. Compared to directly feeding solvents and powders into the first container 21, it prevents interference between the feeding mechanism 5 and the stirring mechanism 4, which could prevent the solvents and powders from being fed into the first container 21. In summary, the combined action of the first container 21, the second container 22, and the transport hole 23 ensures that the solvents and powders are fed normally into the first container 21, and also ensures the normal operation of the stirring mechanism 4, preventing solvent splashing. The guide surface 24 allows the solvents and powders to quickly enter the first container 21 from the second container 22.

[0080] In one embodiment of this application, please refer to Figures 1 to 9 The receiving box 2 further includes a plurality of lugs 25 , and the plurality of lugs 25 are all connected to the first box body 21 .

[0081] The cover plate 41 includes a plate body 411, multiple sliding rods 412, multiple limit blocks 413 and multiple stirring elastic structures 414. The multiple sliding rods 412 are all connected to the plate body 411, and are passed through the multiple lugs 25, and are arranged one-to-one with the multiple lugs 25. The multiple stirring elastic structures 414 are sleeved on the multiple sliding rods 412, and are arranged one-to-one with the multiple sliding rods 412. The stirring elastic structures 414 are elastically supported between the lugs 25 and the plate body 411.

[0082] The stirring assembly 42 includes a rotating shaft 421, a stirring rod 422 and a grip 423. The rotating shaft 421 is rotatably arranged in the plate body 411 around a first direction. The stirring rod 422 is connected to one end of the rotating shaft 421 and is located on the side of the plate body 411 facing the first box body 21. The grip 423 is connected to the end of the rotating shaft 421 away from the stirring rod 422.

[0083] With this configuration, during the mixing process, the testing personnel can press the plate 411 to cover the container 2. By rotating the handle 423, and with the cooperation of the rotating shaft 421, the stirring rod 422 can agitate the solvent and powder, ensuring thorough mixing. The plate 411 prevents the solvent and powder from splashing during mixing. The multiple lugs 25 and multiple sliding rods 412 guide the plate 411, improving its stability in the first direction and preventing it from jamming. The multiple elastic stirring structures 414 allow the testing personnel to reset the plate 411 after mixing, facilitating future use. Furthermore, the multiple elastic stirring structures 414 ensure that the container 2 remains open after mixing, allowing formaldehyde to enter. The multiple limiting blocks 413 prevent multiple sliding rods 412 from coming off the lugs 25, which helps to improve the structural stability between the plate 411 and the housing 2.

[0084] Optionally, the stirring elastic structure 414 is configured as a spring.

[0085] In one embodiment of this application, see [reference] Figures 1 to 9 The operating table 1 also includes multiple guide rods 13, which are all connected to the table body 11 and pass through the feeding plate 51.

[0086] With this configuration, the feeding plate 51 can be guided by the multiple guide rods 13, which helps to improve the stability of the feeding plate 51 in the second direction and prevent the feeding plate 51 from jamming.

[0087] The working principle of this application is as follows: When using this device to detect indoor formaldehyde content, the testing personnel move the feeding plate 51 along the second direction until the feeding plate 51 moves above the second box 22. The testing personnel press the pressure block 5334, which, through the pressing push rod 5333, drives the cutting blade 5335 to move along the second direction toward the end of the second tube 552. During this process, under the action of the pressure block 5334, the cutting elastic structure 5336 is gradually compressed. After the cutting blade 5335 cuts the end of the second tube 552, the powder in the first tube 551 and the second tube 552 falls from the cut point of the second tube 552, and the absorbent (powder) falls into the second box 22 through the filter screen 536. The waste formed after the second tube 552 is cut is filtered by the filter screen 536 and finally slides out from the opening 535. At this point, the inspector releases the pressure block 5334, and under the action of the cutting elastic structure 5336, the pressure block 5334 begins to reset. The pressure block 5334 drives the cutting blade 5335 to reset by pressing the push rod 5333. The inspector pushes the piston push rod 544. At this time, the pressure inside the storage cylinder 542 rises until the pressure inside the storage cylinder 542 exceeds the elastic force of the sealing elastic structure 5283 acting on the sealing plate 5282. The sealing plate 5282 gradually moves away from the partition 522 along the first direction, and the sealing elastic structure 5283 is gradually compressed, connecting the first solvent passage 523 and the mounting cylinder 521. The inspector continues to push the piston push rod 544, and the diluent in the storage cylinder 542 flows sequentially through the second solvent passage 526, the solvent channel 525, the first solvent passage 523, and the mounting cylinder 521 into the second box 22. After the diluent enters the second container 22, it carries the absorbent through the transport hole 23 into the first container 21. Once the diluent and absorbent are inside the first container 21, the operator presses the plate 411, causing it to move towards the first container 21 in the first direction. The stirring elastic structure 414 is gradually compressed until the plate 411 covers the first container 21. The operator then rotates the handle 423, which, through the shaft 421, drives the stirring rod 422 to rotate. Under the action of the stirring rod 422, the absorbent and diluent are thoroughly mixed. After mixing, the operator releases the plate 411, which gradually returns to its original position under the action of the stirring elastic structure 414. At this point, the plate 411 separates from the first container 21. The operator then places the device indoors and allows it to stand for half an hour. After standing, the operator squeezes the color developer into the first container 21 according to the above working principle and stirs the color developer according to the same principle. After the solvent develops its color, the testing personnel compare the solvent color with the colorimetric board 3 to determine the indoor formaldehyde content. After the test is completed, the testing personnel remove the container 2 from the container cavity 12 and then clean the container 2.
