Description

Technical Field

[0001] The invention relates to the technical field of burners, and in particular to a burner with an anti-scalding function. Background Art

[0002] Burner is a general term for devices that spray fuel and air in a certain way for mixed combustion. Burners are divided into industrial burners, burners, civil burners, and special burners according to their types and application fields. They are mostly made of corrosion-resistant and high-temperature resistant materials such as stainless steel or titanium. The function of the burner is to atomize the sample through flame combustion. The atomized test solution enters the burner, and under the action of the flame temperature and flame atmosphere, it undergoes processes such as drying, melting, evaporation, and dissociation to produce a large number of ground state atoms, as well as some excited state atoms, ions, and molecules. A well-designed burner should have high atomization efficiency, low noise, and stable flame performance to ensure high absorption sensitivity and measurement precision. Slit burners are often used to produce atomic vapor in atomic absorption spectrometry. Depending on the type of gas and combustion-supporting gas used, the length and width of the burner gap are different. Generally, the applicable gas and combustion-supporting gas are marked on the burner.

[0003] After the existing burner is used, the fire outlet pipe is burned by the flame for a long time, which makes the surface temperature of the fire outlet pipe very high, and the fire outlet pipe has no protection function. If someone accidentally touches the fire outlet pipe, it may cause burns and cause harm to the staff. Summary of the invention

[0032] Reference Figures 1 to 4 The present invention proposes a burner with an anti-scalding function, comprising a burner body 1, a fire outlet pipe 2 is fixed to the side wall of the burner body 1, the bottom of the burner body 1 is fixedly connected to the top of a placement plate 14, the bottom of the placement plate 14 is fixedly connected to the top of a telescopic rod 13, the telescopic rod 13 passes through the top of a fixing seat 11, the bottom of the telescopic rod 13 is fixedly connected to the top of a support block 12, the support block 12 is fixed to the inner wall of the fixing seat 11, the bottom of the fixing seat 11 is fixedly connected to the top of a universal wheel 16, a connecting plate 3 is fixed to the left side of the burner body 1, the inner wall of the connecting plate 3 is provided with a first slide groove 5, the inner wall of the first slide groove 5 A slider 6 is installed on the wall slide, and the slider 6 passes through the left side of the connecting plate 3, and the slider 6 can move at the penetration point of the connecting plate 3. A protective cover 7 is fixed to the side of the slider 6 away from the first slide groove 5. Two groups of protective covers 7 are provided, and the two groups of protective covers 7 are symmetrically arranged with the center line of the fire outlet pipe 2 in the vertical direction as the symmetry axis. A handle 10 is fixed to the outer wall of the protective cover 7, and a first spring 4 is fixed to the side wall of the slider 6. The side of the first spring 4 away from the slider 6 is fixed to the inner wall of the connecting plate 3. By setting the first spring 4, the protective cover 7 can be reset. A limiting mechanism 8 is provided in the connecting plate 3, and an adjustment mechanism 15 is provided inside the fixed seat 11.

[0033] The above-mentioned limiting mechanism 8 includes a slide bar 81, a second spring 82, a connecting block 83, a push rod 84, a push block 85, a sleeve 86, a third spring 87 and a limiting block 88. The slide bar 81 is slidably mounted on the inner wall of the connecting plate 3. The outer wall of the slide bar 81 is fixed with the second spring 82. The side of the second spring 82 away from the slide bar 81 is fixed on the connecting block 83. The connecting block 83 is fixed to the inner wall of the connecting plate 3. The end of the slide bar 81 away from the connecting block 83 is fixed with a sleeve 86. The inner wall of the sleeve 86 is fixed with a third spring 87. The side wall of the third spring 87 is fixed with a limiting block 88. The limiting block 88 The push rod 84 is fixed on the inner wall of the sleeve 86, and the outer wall of the slide bar 81 is fixed with a push rod 84. A push block 85 is fixed on the end of the push rod 84 away from the slide bar 81. There are two groups of push blocks 85, and the two groups of push blocks 85 are symmetrically arranged with the center line of the fire outlet pipe 2 in the vertical direction as the symmetry axis. Then, when the burner body 1 is not used, the two groups of push blocks 85 can be pushed to approach the connecting plate 3, so that the push rod 84 drives the slide bar 81 to approach the first spring 4, so that the slide bar 81 drives the sleeve 86 to move, so that the top of the limit block 88 does not contact the bottom of the slide block 6. Because the slide block 6 is provided with a through hole 9, the slide bar 8 1 penetrates the through hole 9. When the limit block 88 moves to align with the through hole 9, the limit block 88 does not limit the slider 6. Because the first spring 4 is in a compressed state, the slider 6 drives the two sets of protective covers 7 to approach each other, so that the protective cover 7 covers the fire outlet pipe 2 for protection, to prevent someone from accidentally touching the fire outlet pipe 2 due to the hot surface after using the fire outlet pipe 2, causing burns, thereby playing a scalding prevention function.

The first spring 4 is compressed. When the protective cover 7 drives the slider 6 to move to the specified position, the through hole 9 of the slider 6 will contact the inclined surface of the limit block 88, and then the through hole 9 of the slider 6 will squeeze the inclined surface of the limit block 88, so that the limit block 88 moves into the sleeve 86, and the third spring 87 is compressed. When the slider 6 moves to the side of the limit block 88 close to the connecting block 83, because the first spring 4 is in a compressed state, the bottom of the slider 6 will fit with the top of the limit block 88, and then the limit block 88 will limit the slider 6, so that the protective cover 7 is fixed and reset, and the next protection operation is carried out.

[0034] The above-mentioned adjustment mechanism 15 includes a threaded rod 151, a threaded sleeve 152, a second slide groove 153, a turning handle 154 and a movable rod 155. One end of the threaded rod 151 is rotatably mounted on the inner wall of the fixed seat 11, and the other end of the threaded rod 151 is fixed with the turning handle 154. The outer wall of the threaded rod 151 is threadedly connected with the threaded sleeve 152. The bottom of the threaded sleeve 152 is slidably mounted on the inner wall of the second slide groove 153. The second slide groove 153 is provided on the inner wall of the fixed seat 11. When the threaded sleeve 152 slides in the second slide groove 153, it can guide the threaded sleeve 152. The top of the threaded rod 151 is hinged with a movable rod 155, the movable rod 155 passes through the top of the fixed seat 11, and the movable rod 155 can move at the penetration point of the fixed seat 11, and the end of the movable rod 155 away from the threaded sleeve 152 is hinged at the bottom of the placement plate 14, and then when the handle 154 is turned, the threaded rod 151 can be rotated. The threaded rod 151 is a bidirectional thread, and then the two groups of threaded sleeves 152 can be moved away from or close to each other on the threaded rod 151, and then the upper and lower positions of the placement plate 14 can be adjusted through the movable rod 155, which can play the effect of adjusting the burner body 1, making it convenient to use the burner body 1 and making the device more practical.

[0035] When the burner body 1 is used, the two push blocks 85 can be pushed toward the connecting plate 3, so that the push rod 84 drives the slide bar 81 toward the first spring 4, and the slide bar 81 drives the sleeve 86 to move, so that the top of the limit block 88 does not contact the bottom of the slider 6. Because the slider 6 is provided with a through hole 9, the slide bar 81 passes through the through hole 9. When the limit block 88 moves to align with the through hole 9, the limit block 88 does not limit the slider 6. Because the first spring 4 is in a compressed state, the slider 6 drives the two sets of protective covers 7 to approach each other, so that the protective cover 7 covers the fire pipe 2 for protection, to prevent the fire pipe 2 from being accidentally touched by someone after use. Burns, when the fire pipe 2 needs to be used, the handle 10 can be pulled to move, so that the handle 10 drives the protective cover 7 away from the fire pipe 2. When the protective cover 7 drives the slider 6 to move to the specified position, The through hole 9 of the slider 6 is made to contact with the inclined surface of the limit block 88, which will cause the through hole 9 of the slider 6 to squeeze the inclined surface of the limit block 88, so that the limit block 88 moves into the sleeve 86, compressing the third spring 87. When the slider 6 moves to the side of the limit block 88 close to the connecting block 83, because the first spring 4 is in a compressed state, the bottom of the slider 6 is made to fit with the top of the limit block 88, so that the limit block 88 limits the slider 6, fixes the protective cover 7 and resets it for the next protection operation. When the turning handle 154 is turned, the threaded rod 151 can be rotated. The threaded rod 151 is a bidirectional thread, so that the two sets of threaded sleeves 152 can be moved away from or close to each other on the threaded rod 151, and then the upper and lower positions of the placement plate 14 can be adjusted through the movable rod 155, so as to achieve the effect of adjusting the burner body 1, facilitate the use of the burner body 1, and make the device more practical.
