Abstract
Description
Technical Field
[0001] This invention relates to the field of combustion equipment technology, and more specifically to a combustibility testing device for building energy-saving materials. Background Technology
[0002] In the utility model entitled "A Combustibility Testing Device for Building Energy-Saving Materials" (publication number: CN217133076U, publication date: 2022-08-05), a testing mechanism is included. This mechanism comprises a fixed plate, a slide rail, a vertical block, a horizontal bar, a moving block, a rubber pad, and a U-shaped plate. The top of the fixed plate is fixedly connected to the U-shaped plate, and the top of the fixed plate is also fixedly connected to the slide rail. By gripping the U-shaped handle and moving it upwards, the U-shaped handle moves the insert rod through the moving block, separating it from the rubber pad. Moving the U-shaped handle to the left causes the vertical bar to move the corresponding second U-shaped block to fix the building material. Lighting an alcohol lamp and moving the slider to the left moves the alcohol lamp via an electric telescopic rod. Activating the electric telescopic rod moves the alcohol lamp upwards, facilitating the ignition of the building material. This allows for the simultaneous fixing of multiple building materials of different specifications, resulting in high testing efficiency. The alcohol lamp does not burn in vain, preventing significant waste. It also facilitates timing and provides great convenience for the user.
[0003] In the prior art, including the aforementioned patent, during combustion tests, generally speaking, the more combustible material there is, the more oxygen is required. Therefore, the weight of the combustible material is usually directly proportional to the amount of oxygen needed to sustain its combustion. With the same mass of combustible material, if less air is introduced into the container, the combustible material will not burn completely, resulting in the production of toxic and harmful carbon monoxide, which will be released into the air and cause pollution. If too much air is introduced into the container, although it will not cause incomplete combustion of the combustible material, the excessive air will result in waste. Summary of the Invention

Seals: They are slidably connected in the corresponding air intake channel and are used to adjust the opening of the air intake channel; Transmission assembly: It connects to the combustion chamber and seals; As the mass of the fuel drives the combustion platform to move downwards, it moves the transmission components, causing the seals to adjust the opening of the air intake passage, thereby regulating the amount of air entering the tank.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.
[0022] Reference Figure 1-8 As shown, the present invention provides a flammability testing device for building energy-saving materials, including a tank 1 and two through-connected air inlet channels 1.1 disposed on the tank 1, and further including a combustion platform 1.5: which is slidably connected to the axial direction of the tank 1; Seal 1.7: It is slidably connected in the corresponding air intake channel 1.1 and is used to adjust the opening of the air intake channel 1.1; Transmission assembly: It is connected to the combustion chamber 1.5 and the seal 1.7; When the mass of the combustible fuel on the combustion platform 1.5 drives the combustion platform 1.5 to move downwards, it drives the transmission component to move, causing the seal 1.7 to move, thereby adjusting the opening of the air intake channel 1.1, and thus adjusting the air intake volume in the tank 1.
[0023] Specifically, an exhaust channel 1.2 is connected to the top of the tank body 1. Two air intake channels 1.1 are formed around the periphery of the tank body 1. Each air intake channel 1.1 has a cross-section that is wider at both ends and narrower in the middle. A sealing element 1.7 is slidably connected to each air intake channel 1.1 along its axial direction. By sliding the sealing element 1.7, the position of the sealing element 1.7 within the air intake channel 1.1 is changed, thereby adjusting the volume of air entering the air intake channel 1.1, so that the combustible material in the tank body 1 can be fully burned. An ash discharge channel 1.3 is connected to the bottom of the tank body 1. A valve or baffle is installed on the ash discharge channel 1.3 to open or close the sealing element 1.7.
[0024] A sealing cover is rotatably connected to the tank body 1 for opening or closing the tank body 1. Inside the tank body 1, above each air intake channel 1.1, a combustion platform 1.5 is slidably connected. The combustion platform 1.5 moves axially in the tank body 1. The distance the combustion platform 1.5 moves downward is related to the weight of the combustible material on the combustion platform 1.5. An electronic igniter is installed on the combustion platform 1.5, and its control switch is installed on the outside of the tank body 1.
[0025] Transmission assembly: It is installed inside the tank 1. One end of the transmission assembly is connected to the combustion platform 1.5, and the other end is connected to each seal 1.7. In this embodiment, the transmission assembly converts vertical movement into horizontal movement. In the prior art, mechanical transmission mechanisms that can convert vertical movement into horizontal movement are also applicable to this embodiment. The mass of the combustible material placed on the combustion platform 1.5 causes the combustion platform 1.5 to move downward, thereby causing each seal 1.7 to move within the air intake channel 1.1, thereby adjusting the opening of the air intake channel 1.1.
[0026] When in use, when the user places the combustible material on the combustion platform 1.5, the combustion platform 1.5 moves vertically downward along the axis of the tank body 1 under the action of gravity. As the combustion platform 1.5 moves downward, it drives the transmission component to move, which in turn drives each seal 1.7 to open the air intake channel 1.1, thereby adjusting the opening degree of the air intake channel 1.1.
[0027] The present invention provides a combustibility testing device for building energy-saving materials, which adjusts the opening of the air inlet channel 1.1 by the weight of the combustible material placed on the fuel platform, thereby adjusting the volume of air entering the tank 1 so that the air in the tank 1 can maintain the complete combustion of the combustible material.
[0028] Referring to 1, 3-4, in another embodiment of the present invention, a fixed seat 1.4 is fixedly connected inside the tank 1, and a combustion platform 1.5 is slidably connected on the fixed seat 1.4.
[0029] The transmission assembly includes a connector and a drive component. The connector is installed between the drive component and the combustion platform 1.5, and the drive component is used to connect with each seal 1.7.
[0030] The driving component includes a transmission seat 1.44, on which a wedge-shaped groove 1.442 is provided at the position corresponding to each seal 1.7, and a transmission pin 1.60 adapted to the wedge-shaped groove 1.442 is fixedly connected to each seal 1.7.
[0031] The connector includes a transmission column 1.50 fixedly connected between the transmission base 1.44 and the combustion platform 1.5. A third spring 1.51 is sleeved on the outside of the transmission column 1.50, and one end of the third spring 1.51 is fixedly connected to the fixed base 1.4.
[0032] Specifically, a fixed base 1.4 is fixedly connected above each air intake channel 1.1 inside the tank body 1. A combustion platform 1.5 is mounted on the fixed base 1.4. A transmission column 1.50 is fixedly connected to the combustion platform 1.5. A transmission seat 1.44 is fixedly connected to the bottom end of the transmission column 1.50. A wedge-shaped groove 1.442 is opened on the transmission seat 1.44 at the position corresponding to each seal 1.7. A connecting pin 1.70 adapted to the wedge-shaped groove 1.442 is fixedly connected to each seal 1.7. The connecting pins 1.70 on each seal 1.7 are respectively located in the wedge-shaped groove 1.442 provided with them. Figure 2-4 As shown, a third spring 1.51 is sleeved on the outside of the transmission column 1.50. One end of the third spring 1.51 is fixedly connected to the fixed seat 1.4, and the other end of the third spring 1.51 is fixedly connected to the transmission seat 1.44, so that the combustion platform 1.5 moves downward after being subjected to force, and can be reset as its weight decreases during the combustion process of the combustible material.
[0033] In use, when combustible material is placed on the combustion platform 1.5, the weight of the combustible material causes the combustion platform 1.5 to move downward. During the downward movement of the combustion platform 1.5, the third spring 1.51 is compressed, causing the combustion platform 1.5 to drive the transmission column 1.50 to move downward. In turn, the transmission column 1.50 drives the transmission seat 1.44 to move, which in turn causes the transmission seat 1.44 to drive each seal 1.7 to move within the air intake channel 1.1, thereby adjusting the opening of the air intake channel 1.1.
[0034] Reference Figure 3-6 As shown, in another embodiment provided by the present invention, it further includes: a rotating scraper seat 1.6, which is rotatably connected to the fixed seat 1.4, and the rotating scraper seat 1.6 is driven by the transmission column 1.50.
[0035] Among them, such as Figure 3 As shown, a transmission groove 1.501 is formed around the periphery of the transmission column 1.50. A transmission pin 1.60 that is compatible with the transmission groove 1.501 is fixedly connected to the rotating scraper seat 1.6. The transmission groove 1.501 has a spiral structure and the two ends of the transmission groove 1.501 are connected through each other.
[0036] In this embodiment, the preferred embodiment is shown in Figure 6. The transmission groove 1.501 can be divided into a first loop segment 1.5011, a second loop segment 1.5012, etc. The compression of the third spring 1.51 can be adjusted according to the weight of the combustible material. The height of the first loop segment is less than that of the second loop segment, and the first and second loop segments form a spiral structure. The beginning and end of the first or second loop segment are connected, and the first and second loop segments can be connected. This design is because when the weight of the combustible material is light, the compression of the third spring 1.51 is small, so its deformation is much smaller than the maximum deformation. The elastic force generated when it resets will be small. After the combustible material burns, the ash also has a certain weight. When the weight of the spring generated by the third spring 1.51 is equal to the weight of the combustion platform 1.5 and the ash, the force will reach a balanced state.
[0037] A deceleration assembly is provided on the fixed base 1.4. When the third spring 1.51 is compressed to its maximum deformation, it dynamically limits the combustion platform 1.5, so that the rotating scraper 1.6 can be subjected to force with the combustion platform 1.5.
[0038] The reduction assembly includes a transmission element 1.45 and a locking element for limiting the transmission seat 1.44.
[0039] The locking element includes two locking blocks 1.46 that are slidably connected in the radial direction to the fixed base 1.4, and each locking block 1.46 is slidably connected to the transmission element 1.45.
[0040] Two sliding grooves 1.40 are respectively formed radially on the fixed base 1.4. The sliding grooves 1.40 are collinear in the horizontal direction. A transmission component 1.45 is slidably connected at a position perpendicular to the two sliding grooves 1.40. A first spring 1.401 is fixedly connected in each sliding groove 1.40, and a matching plug block 1.43 is slidably connected in each sliding groove 1.40. The other end of each first spring 1.401 is fixedly connected to the corresponding plug block 1.43. On each of the 1.43 plug-in blocks, a slanted groove adapted to the transmission component 1.45 is formed. A limiting groove 1.42 is formed on the fixed base 1.4 at the position of each sliding groove 1.40. A sliding rod 1.441 is fixedly connected on the transmission base 1.44 at the position corresponding to each limiting groove 1.42. Multiple plug-in grooves adapted to the plug-in blocks 1.43 are formed on each sliding rod 1.441 at linearly equidistant positions on one side of each plug-in block 1.43. Figure 4-5 As shown.
[0041] A locking block 1.46 is slidably connected to one side of the fixed base 1.4 corresponding to the transmission component 1.45. The locking block 1.46 is mounted on the fixed base 1.4 by a second spring 1.402. A first wedge-shaped abutment is provided on the locking block 1.46. A second wedge-shaped abutment that matches the first wedge-shaped abutment is fixedly connected to the combustion platform 1.5.
[0042] As the transmission seat 1.44 moves downward, the locking block 1.46 locks and limits the transmission component 1.45. At this time, each plug-in block 1.43 is separated from the corresponding slide rod 1.441, meaning the transmission seat 1.44 moves downward unrestricted. When the third spring 1.51 is compressed to its maximum deformation, the second abutment part on the combustion platform 1.5 abuts against the first abutment part on the locking block 1.46, thereby unlocking the locking block 1.46 from the transmission component 1.45. Then, the plug-in block 1.43 dynamically locks the slide rod, thereby buffering the reset speed of the transmission seat 1.44, allowing the rotating scraper to scrape the ash at the bottom of the combustion platform 1.5. During this process, the plug-in block 1.43 dynamically limits the unlocking and locking of the slide rod. During this process, the transmission component 1.45 moves on the fixed seat 1.4, but the transmission component 1.45 cannot abut against the locking block 1.46, that is, the locking block 1.46 does not lock and limit the transmission component 1.45 during this process.
[0043] During use, when combustible material is placed on the combustion platform 1.5, the combustion platform 1.5 moves vertically downward along the axis of the tank body 1 under the action of gravity. As the combustion platform 1.5 moves downward, it drives the transmission column 1.50 to move downward, causing the transmission seat 1.44 to move downward. As the transmission seat 1.44 moves downward, it drives the movement of each sealing element 1.7, thereby adjusting the opening of the passage.
[0044] When the combustion platform 1.5 moves downward to its lowest point, the second wedge-shaped part abuts against the first wedge-shaped part of the locking block 1.46, thereby unlocking the transmission component 1.45 and dynamically limiting the sliding rod with the plug-in block 1.43. During this process, the transmission groove 1.501 drives the rotating scraper 1.6 to rotate, scraping away the ash on the combustion platform 1.5. After the combustion platform 1.5 is reset, the transmission component 1.45 is manually moved, causing the locking block 1.46 to lock and limit the transmission component 1.45.
[0045] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
