Description

Technical Field

[0002] During decoration, decoration materials such as plywood, paint, coating, carpet, etc. may release formaldehyde, so indoor formaldehyde pollution is a common problem in the decoration process. During decoration and living, long-term exposure to high concentrations of formaldehyde will cause harm to human health, so effective measures need to be taken to detect and control formaldehyde.

[0003] At present, when decorating and living, formaldehyde self-test kits are usually used to detect indoor formaldehyde content. The formaldehyde self-test kit is a self-test product that reflects the formaldehyde content through color reaction, which can quickly and semi-quantitatively experience formaldehyde to determine the degree of formaldehyde pollution. The formaldehyde self-test kit includes an adsorbent, a diluent, a color developer, a container box and a colorimetric card. During use, the adsorbent and the diluent need to be poured into the container box first, and after mixing evenly, the container box is placed indoors and left to stand for thirty minutes. After standing, the color developer is poured into the container box to color the solution in the container box. After color development, the solution is compared with the colorimetric card, so that the indoor formaldehyde content can be obtained. However, in actual use, it is necessary to tear the packaging of the adsorbent, diluent and color developer in turn, which is cumbersome to operate, and the liquid is easy to splash, which easily leads to poor detection accuracy.

[0025] like Figures 1 to 9 As shown, the present application provides a quality inspection device for interior decoration, including an operating table 1, a storage 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 storage cavity 12, and the storage cavity 12 is opened in the table body 11. The storage box 2 is placed in the storage 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, the cover plate 41 is slidably covered on the storage box 2 along a first direction, and the stirring assembly 42 is installed on the cover plate 41. The feeding mechanism 5 includes a feeding plate 51, at least one solvent joint 52, a powder joint 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 the second direction. The at least one solvent joint 52 and the powder joint 53 are both connected to the feeding plate 51. The at least one solvent storage assembly 54 is detachably mounted on the at least one solvent joint 52 and is arranged one-to-one with the at least one solvent joint 52. The at least one solvent storage assembly 54 is also configured to feed the solvent into the containing box 2 after the solvent joint 52 moves along the second direction to align with the containing box 2. The plurality of powder storage tubes 55 are all plugged into the powder joint 53. The plurality of powder storage tubes 55 are also configured to feed the powder into the containing box 2 after the powder joint 53 moves along the second direction to align with the containing box 2.

[0026] It should be noted that the first direction mentioned above and below refers to the bidirectional direction of the shortest connection line between the cover plate 41 and the receiving box 2. Figure 1 The second direction above and below refers to the bidirectional direction of the shortest line between the stirring assembly 42 and the feeding plate 51, as shown in FIG. Figure 1 The Y-axis shown in .

[0027] It should also be noted that in this embodiment, the number of solvent connectors 52 is set to two for illustration. Of course, in other embodiments, according to actual application requirements, the number of solvent connectors 52 can also be set to one, three, four...other numbers, which are not limited here. Since the solvent storage components 54 and the solvent connectors 52 are set 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 of the solvent storage components 54 is used to store a diluent, and the other solvent storage component 54 is used to store a developer. The powder storage tube 55 is used to store an adsorbent.

[0028] The present application provides a quality inspection device for interior decoration. During use, the absorbent can be fed into the containing box 2 through the feeding plate 51, in cooperation with the powder joint 53 and the powder storage tube 55. With the cooperation of the solvent joint 52 and the solvent storage assembly 54, the diluent and the developer can be fed into the containing box 2. Compared with the related art, there is no need to tear the packaging of the absorbent, diluent and 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 is convenient for the absorbent to absorb formaldehyde and helps to improve the detection accuracy. The stirring assembly 42 can also be used to stir the developer, so that the 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 then 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 box 2 to prevent the absorbent, diluent and developer from splashing out of the container box 2, thereby preventing the detection agent from reducing and affecting the detection accuracy, and preventing the detection agent from splashing onto the body surface of the detection personnel. The container box 2 is directly placed in the platform 11, and after the detection is completed, the detection personnel can directly take out the container box 2 for cleaning, which is convenient to use.

[0029] In one embodiment of the present application, see Figures 1 to 9 The solvent connector 52 includes a mounting tube 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 tube 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 tube 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 communicated with the first solvent through hole 523. The plurality of second solvent through holes 526 are all opened on the pointed cone 524 and communicated with the solvent channel 525 and are arranged at intervals.

[0030] 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.

[0031] It should be noted that at present, formaldehyde self-test kits are usually disposable. When decorating and living, it is usually necessary to test the indoor formaldehyde content multiple times to monitor the changes in indoor formaldehyde content. Therefore, during each test, the packaging of the test agent needs to be torn, which greatly increases the risk of leakage of the test agent and is cumbersome to operate.

[0032] With such a configuration, the inspector can squeeze the solvent in the storage cylinder 542 into the containing box 2 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 by pressing the piston push rod 544. Compared with the related art, there is no need to tear the package, which effectively avoids the leakage of the solvent, and is convenient to use. In addition, since the connecting cylinder 541 is screwed to the mounting cylinder 521, the connecting cylinder 541 can be removed from the mounting cylinder 521. When the solvent in the storage cylinder 542 is exhausted, the inspector can replace it by disassembling the connecting cylinder 541. Compared with the related art, when multiple tests are performed indoors, there is no need to repeatedly tear the package, which also effectively avoids the leakage of the solvent, and the replacement is convenient, which helps to improve the convenience of use. Under the joint action of the piston push rod 544 and the sealing block 543, the solvent can be sealed in the storage cylinder 542 and the connecting cylinder 541, and the solvent can be prevented from leaking from the storage cylinder 542 and the connecting cylinder 541, and the sealing effect is good. After replacing the solvent storage assembly 54, the sealing block 543 can be pierced through the pointed cone 524, so as to prevent the sealing block 543 from interfering with the flow of the solvent during the detection process.

[0033] Optionally, the storage cartridge 542 is made of a transparent material.

[0034] With this arrangement, the inspector can directly observe the change in the solvent capacity in the storage cylinder 542 from the outside.

[0035] Optionally, the solvent storage assembly 54 further includes a scale line 545 , which is opened on the outer circumference of the storage cylinder 542 .

[0036] With such arrangement, when squeezing out the solvent, the inspector can squeeze out the target volume of solvent through the scale line 545, which helps to improve the detection accuracy of the detection device.

[0037] In one embodiment of the present application, please refer to Figures 1 to 9 The solvent connector 52 further includes a mounting frame 527 and a blocking member 528. The mounting frame 527 is connected to the inner circumference of the mounting cylinder 521 and is located on the side of the partition 522 facing the platform 11. The blocking member 528 is slidably mounted on the mounting frame 527 along a first direction.

[0038] The blocking member 528 includes a blocking rod 5281, a blocking plate 5282 and a blocking elastic structure 5283. The blocking rod 5281 is slidably arranged on the mounting frame 527 along a first direction. The blocking plate 5282 is connected to one end of the blocking rod 5281 and is located between the partition plate 522 and the mounting frame 527. The blocking elastic structure 5283 is sleeved on the blocking rod 5281 and elastically supported between the mounting frame 527 and the blocking plate 5282.

[0039] With such a configuration, when there is no need to squeeze out the solvent, the sealing plate 5282 can be held against the partition 522 under the action of the sealing elastic structure 5283, so that the sealing plate 5282 can shield the first solvent through hole 523, thereby preventing the solvent from leaking and achieving a good sealing effect. Moreover, under the action of the sealing elastic structure 5283 and the sealing plate 5282, it is also possible to prevent the solvent from directly contacting the external environment and causing the solvent to be contaminated. When the solvent needs to be squeezed out, the inspector pushes the piston push rod 544 so that the pressure in the storage cylinder 542 is greater than the elastic force of the sealing elastic structure 5283 on the sealing plate 5282, so that the solvent can flow out of the storage cylinder 542.

[0040] Optionally, the blocking elastic structure 5283 is configured as a spring.

[0041] In one embodiment of the present application, see Figures 1 to 9 The powder connector 53 includes a placement tube 531, a placement rack 532 and a cutting piece 533. The placement tube 531 is connected to the feeding plate 51 and passes through the feeding plate 51. The placement rack 532 is connected to the inner circumference of the placement tube 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 tube 531 along a third direction and is configured to cut the end of the powder storage tube 55.

[0042] It should be noted that the third direction mentioned above and below refers to the bidirectional direction of the shortest connection line between the two ends of the placement tube 531. Figure 1 The Z axis shown in .

[0043] With such a configuration, during use, the amount of powder added can be easily controlled through the powder storage tube 55, which helps to improve the detection accuracy. In addition, under the action of the cutting piece 533, the end of the powder storage tube 55 can be cut, so that the powder can be taken out from the powder storage tube 55. Under the action of the placement rack 532, multiple powder storage tubes 55 can be placed in the placement tube 531, which is convenient for cutting by the cutting piece 533, which helps to improve the convenience of use.

[0044] In one embodiment of the present application, see Figures 1 to 9 The powder connector 53 further includes a slide rail 534 , which is connected to the outer peripheral side of the placement cylinder 531 .

[0045] 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 penetrated 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.

[0046] With such arrangement, during the cutting process, the cutting knife 5335 can move along the third direction through the slide rail 534 and the slider 5331, so that the cutting knife 5335 can be used to cut any powder storage tube 55, which is convenient to use. Moreover, after the cutting knife 5335 has finished cutting, under the action of the cutting elastic structure 5336, the cutting knife 5335 can be driven to reset through the pressing block 5334 and the pressing push rod 5333, which is convenient for the next use, and helps to improve the convenience of use.

[0047] Optionally, the cut elastic structure 5336 is configured as a spring.

[0048] In one embodiment of the present application, please refer to Figures 1 to 9 The powder connector 53 further includes an opening 535 and a filter screen 536 . The opening 535 is provided at one end of the placement tube 531 close to the feeding plate 51 . The filter screen 536 is installed on the inner circumference of the placement tube 531 and extends to the outside of the placement tube 531 through the opening 535 .

[0049] With such arrangement, during the cutting process, the powder in the powder storage tube 55 falls into the containing box 2 through the filter screen 536. The cutting waste of the powder storage tube 55 is filtered through the filter screen 536 and finally slides out of the placing tube 531 through the opening 535, thereby preventing the cutting waste of the powder storage tube 55 from falling into the containing box 2 and affecting the detection accuracy of the detection device.

[0050] In one embodiment of the present application, see 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 tube 531. The plurality of first through holes 5322 are all opened in the first placement plate 5321 and are arranged at intervals. The second placement plate 5323 is connected to the inner circumference of the placement tube 531 and is located on the side of the first placement plate 5321 facing the table body 11 and is arranged at intervals from the first placement plate 5321. The plurality of second through holes 5324 are all opened in the second placement plate 5323 and are arranged at intervals. The diameter of the first through hole 5322 is greater than the diameter of the second through hole 5324.

[0051] The powder storage tube 55 includes a first tube portion 551 and a second tube portion 552 . The second tube portion 552 is connected to the first tube portion 551 . The first tube portion 551 is passed through the first through hole 5322 , and the second tube portion 552 is passed through the second through hole 5324 . The diameter of the first tube portion 551 is greater than the diameter of the second tube portion 552 .

[0052] In 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 to prevent the powder storage tube 55 from falling from 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 direction and the third direction, so that the powder storage tube 55 is stably placed in the placement cylinder 531, which is convenient for cutting by the cutting knife 5335.

[0053] In one embodiment of the present application, see Figures 1 to 9 The containing box 2 includes a first box body 21, a second box body 22, a transport hole 23 and a guide surface 24. The second box body 22 is connected to the first box body 21. The transport hole 23 is opened between the first box body 21 and the second box body 22 and is used to connect the first box body 21 and the second box body 22. The guide surface 24 is opened in the second box body 22 and is used to guide the solution to the transport hole 23.

[0054] With such a configuration, during use, the second box body 22 can be used to receive solvents and powders. Compared with directly feeding the solvents and powders into the first box body 21, it is possible to prevent the feeding mechanism 5 and the stirring mechanism 4 from interfering with each other, which results in the inability to feed the solvents and powders into the first box body 21. In summary, under the joint action of the first box body 21, the second box body 22 and the transport hole 23, it is possible to ensure that the solvents and powders are normally fed into the first box body 21, and it is also possible to ensure that the stirring mechanism 4 operates normally, and avoid splashing of the solvent. Under the action of the guide surface 24, the solvents and powders can quickly enter the first box body 21 from the second box body 22.

[0055] In one embodiment of the present 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 .

[0056] 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.

[0057] 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 one end of the rotating shaft 421 away from the stirring rod 422.

[0058] With such arrangement, during the stirring process, the inspector can cover the plate body 411 with the container box 2 by pressing the plate body 411. The inspector can stir the solvent and the powder by rotating the grip 423, with the cooperation of the rotating shaft 421, and the stirring rod 422 can stir the solvent and the powder so that the solvent and the powder are fully mixed. Under the action of the plate body 411, the solvent and the powder can be prevented from splashing during the stirring process. Under the cooperation of multiple lugs 25 and multiple slide bars 412, the plate body 411 can be guided, which helps to improve the moving stability of the plate body 411 in the first direction and prevent the plate body 411 from getting stuck in the first direction. Under the action of multiple stirring elastic structures 414, the inspector can drive the plate body 411 to reset after the stirring is completed, which is convenient for the next use. Moreover, under the action of multiple stirring elastic structures 414, after the stirring is completed, the container box 2 is always kept in an open state, which is convenient for formaldehyde to enter the container box 2. Under the action of the plurality of limit blocks 413 , the plurality of slide bars 412 can be prevented from escaping from the lugs 25 , which helps to improve the structural stability between the plate body 411 and the receiving box 2 .

[0059] Optionally, the stirring elastic structure 414 is configured as a spring.

[0060] In one embodiment of the present application, see Figures 1 to 9 The operating platform 1 further includes a plurality of guide rods 13 , which are all connected to the platform body 11 and are all disposed through the feeding plate 51 .

[0061] With such arrangement, the feed plate 51 can be guided under the action of the plurality of guide rods 13 , which helps to improve the movement stability of the feed plate 51 in the second direction and prevent the feed plate 51 from getting stuck.

[0062] The working principle of the present application is as follows: when the device is used to detect indoor formaldehyde content, the inspector drives the feed plate 51 to move along the second direction until the feed plate 51 moves to the top of the second box body 22. The inspector presses the pressing block 5334, and the pressing block 5334 drives the cutting knife 5335 to move along the second direction toward the end of the second tube 552 by pressing the push rod 5333. In this process, under the action of the pressing block 5334, the cutting elastic structure 5336 is gradually compressed. After the cutting knife 5335 cuts the end of the second tube 552, the powder in the first tube 551 and the second tube 552 falls from the cutting part of the second tube 552, and the absorbent (powder) falls into the second box body 22 through the filter screen 536. The waste formed after the cutting of the second tube 552 is filtered by the filter screen 536 and finally slides out from the opening 535. The inspector releases the pressing block 5334 at this time, and the pressing block 5334 begins to reset under the action of the cutting elastic structure 5336. The pressing block 5334 drives the cutting knife 5335 to reset by pressing the push rod 5333. The inspector pushes the piston push rod 544. At this time, the pressure in the storage cylinder 542 rises until the pressure in the storage cylinder 542 is greater than the elastic force of the blocking elastic structure 5283 acting on the blocking plate 5282. The blocking plate 5282 gradually moves away from the partition 522 along the first direction, the blocking elastic structure 5283 is gradually compressed, and the first solvent through hole 523 is connected to the installation cylinder 521. The inspector continues to push the piston push rod 544, and the diluent in the storage cylinder 542 flows into the second box body 22 through the second solvent through hole 526, the solvent channel 525, the first solvent through hole 523 and the installation cylinder 521 in sequence. After the diluent enters the second box body 22, the diluent drives the absorbent to flow into the first box body 21 through the transport hole 23. After the diluent and the absorbent enter the first box body 21, the inspector presses the plate body 411, and the plate body 411 moves toward the first box body 21 along the first direction, and the stirring elastic structure 414 is gradually compressed until the plate body 411 covers the first box body 21. The inspector rotates the grip 423, and the grip 423 drives the stirring rod 422 to rotate through the rotating shaft 421. Under the action of the stirring rod 422, the absorbent and the diluent are fully mixed. After the stirring is completed, the inspector releases the plate body 411, and under the action of the stirring elastic structure 414, the plate body 411 gradually resets. At this time, the plate body 411 and the first box body 21 are separated. The inspector places the device indoors and leaves it to stand for half an hour. After the standing is completed, the inspector squeezes the developer into the first box body 21 according to the above working principle, and stirs the developer according to the above working principle. After the solvent develops color, the inspector compares the color of the solvent with the colorimetric plate 3, thereby obtaining the indoor formaldehyde content. After the inspection is completed, the inspector takes the container 2 out of the container chamber 12 and cleans the container 2.
