[0022] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments. Example 1
[0023] like Figure 1-5 As shown, a low-temperature energy-saving heat pump proposed by the utility model includes a heat pump body 1 and a connecting pipe 2, which is connected to the hot air outlet of the heat pump body 1; a prevention mechanism 5 for detecting and processing air tightness is installed at one end of the connecting pipe 2 away from the heat pump body 1.
[0024] Furthermore, the prevention mechanism 5 includes a detection ring 501, which is installed at one end of the connecting pipe 2 away from the heat pump body 1. A plurality of air inlet holes 502 are opened on the inner wall of the detection ring 501, and the plurality of air inlet holes 502 are distributed in a ring array. A transparent early warning ring 503 is embedded in the outer ring surface of the detection ring 501, and a plurality of partition blocks 509 are arranged in the transparent early warning ring 503, and the corresponding air inlet hole 502 is located between two adjacent partition blocks 509. An elastic hot-melt sleeve 504 is sleeved on the outer ring of the detection ring 501, and the elastic hot-melt sleeve 504 is fixedly connected to the detection ring 501 and the plurality of partition blocks 509. The elastic hot-melt sleeve 504 is located at the air inlet hole 502 and is fixedly connected to the surface thereof with a conical crushing block 505, and the conical crushing block 50 5 is located between the elastic hot melt sleeve 504 and the transparent warning ring 503, two second glass interlayers 511 are arranged between two adjacent partition blocks 509, a first glass interlayer 506 is fixedly connected between the two second glass interlayers 511, and the first glass interlayer 506 is located above the cone head of the conical crushing block 505, the upper and lower sides of the first glass interlayer 506 and the transparent warning ring 503 are respectively filled with lipid compound solution 508 and peroxide solution 507, and the two second glass interlayers 511 and the partition block 509 are filled with liquid adhesive 512. When hot gas leaks from the connecting pipe 2 and the external pipe joint, the hot gas will enter the air inlet 502 along with the connecting pipe 2. At this time, the peroxide solution 507 and the lipid compound solution 508 are filled with liquid adhesive 512. Under the wrapping and covering of the liquid solution 508 and the liquid adhesive 512, the heat can be retained at the air inlet 502 to the maximum extent. When the degree of hot air leakage increases and the overflowing hot air is too much, at this time, the hot air pressure at the air inlet 502 increases, which will push the elastic hot melt sleeve 504 to deform, drive the conical breaking block 505 to move toward the first glass interlayer 506, and finally break the first glass interlayer 506, so that the peroxide solution 507 and the lipid compound solution 508 on the upper and lower sides of the first glass interlayer 506 are mixed, thereby generating fluorescence. Through the transparent characteristic of the transparent warning ring 503, it is convenient for users to quickly find the leakage problem, and because the multiple partition blocks 509 separate the transparent warning ring 503 into multiple independent areas , and corresponds to the corresponding air inlet hole 502. This setting can facilitate users to quickly determine the specific leakage location point, which is convenient for subsequent maintenance. When hot air continues to leak in large quantities, the excess hot air will continue to push the elastic hot melt sleeve 504 to squeeze into the transparent warning ring 503, thereby causing the two second glass interlayers 511 to rupture, thereby causing the liquid adhesive 512 on the inside of the two second glass interlayers 511 to flow out. Subsequently, after the elastic hot melt sleeve 504 is overheated and melted or punctured by broken glass, the liquid adhesive 512 flows out through the air inlet hole 502 to between the detection ring 501 and the external pipe joint, and seals the leakage point between the two after solidification. The above structural setting can achieve the goal of preventing the leakage of hot air through the prevention mechanism 5 after the leakage occurs.The trigger response under different heat conditions can achieve the effect from early warning to emergency sealing treatment. On the one hand, it is convenient for users to detect it in time and come for maintenance. On the other hand, it avoids the continuous leakage of hot air and reduces the loss of excess energy of the low-temperature heat pump, thereby achieving energy-saving effects and improving the safety of the low-temperature heat pump during operation.
[0025] Furthermore, a threaded ring 510 is provided on one end of the detection ring 501 away from the connecting tube 2, and the threaded ring 510 is threadedly connected to the detection ring 501, and the transparent warning ring 503 is located between the threaded ring 510 and the detection ring 501. Through this arrangement, it is convenient for users to disassemble and replace the transparent warning ring 503 at any time, thereby achieving the effect of convenient installation and use. At the same time, through the rotation and translation of the threaded ring 510 on the detection ring 501, the transparent warning ring 503 can be abutted and fixed.
[0026] Among them, the connecting pipe 2 is respectively sleeved and fixed with an abutment ring 3 and a sealing ring 4, and the abutment ring 3 is located between the sealing ring 4 and the connecting pipe 2. Through this arrangement, when the external pipe joint is connected to the connecting pipe 2, the abutment ring 3 and the sealing ring 4 can abut and limit it, thereby improving the stability of the external pipe joint and enhancing the air tightness between the two.
[0027] Furthermore, an annular clamping groove 513 is provided on the side of the detection ring 501 opposite to the threaded ring 510, and a convex ring matched with the annular clamping groove 513 is provided on the end of the connecting tube 2 opposite to the detection ring 501, and the convex ring is clamped in the annular clamping groove 513. Through this arrangement, it is convenient for users to disassemble and assemble the detection ring 501, saving installation and replacement time and improving disassembly and assembly efficiency.
[0028] In addition, the conical crushing block 505 is in the shape of a cone, and is made of a material with a high thermal conductivity. Through the above arrangement, when hot gas leakage occurs, the conical crushing block 505 can quickly absorb heat, so that the heat is retained as much as possible in the wrapping covering layer of the peroxide solution 507, the lipid compound solution 508 and the liquid adhesive 512, thereby achieving the effect of reducing heat loss. At the same time, when the hot gas leakage speed is too fast, the conical crushing block 505 conducts too much heat into the peroxide solution 507, so that the pressure in the peroxide solution 507 increases. When the external hot gas pressure pushes the conical crushing block 505 to break the first glass interlayer 506, the rupture of the second glass interlayer 511 can be accelerated, and while achieving the early warning effect, the liquid adhesive 512 is accelerated to flow out, thereby achieving the effect of emergency remediation.
[0029] It is worth noting that multiple fiber filaments are mixed in the liquid adhesive 512. Through this setting, when the liquid adhesive 512 flows out through the air inlet 502 to between the detection ring 501 and the external pipe joint, a more stable bonding relationship can be quickly formed, thereby enhancing the re-sealing effect of the device on the leakage point.
[0030] Working principle: When hot air leaks from the connection pipe 2 and the external pipe joint, the hot air will enter the air inlet 502 along with the connection pipe 2. At this time, under the wrapping and covering of the peroxide solution 507, the lipid compound solution 508 and the liquid adhesive 512, the heat can be retained at the air inlet 502 to the maximum extent. When the degree of hot air leakage increases and the overflowing hot air is too much, at this time, the hot air pressure at the air inlet 502 increases, which will push the elastic hot melt sleeve 504 to deform, drive the conical breaking block 505 to move toward the first glass interlayer 506, and finally break the first glass interlayer 506, so that the peroxide solution 507 and the lipid compound solution 508 on the upper and lower sides of the first glass interlayer 506 are mixed, thereby generating fluorescence. The transparent characteristic of the transparent warning ring 503 can facilitate users to quickly find the leakage problem. Because the multiple partition blocks 509 divide the transparent warning ring 503 into multiple independent areas and correspond to the corresponding air inlet holes 502, this setting can In order to facilitate users to quickly determine the specific leakage location and facilitate subsequent maintenance, when hot air continues to leak in large quantities, the excess hot air will continue to push the elastic hot melt sleeve 504 to squeeze into the transparent warning ring 503, thereby causing the two second glass interlayers 511 to rupture, thereby causing the liquid adhesive 512 on the inside of the two second glass interlayers 511 to flow out, and then after the elastic hot melt sleeve 504 is overheated and melted or pierced by broken glass, the liquid adhesive 512 flows out through the air inlet 502 to between the detection ring 501 and the external pipe joint, and seals the leakage point between the two after solidification. The above structural setting can achieve the effect of triggering reaction from early warning to emergency sealing treatment through the prevention mechanism 5 under different heat conditions after the hot air leaks. On the one hand, it is convenient for users to detect it in time and come for maintenance. On the other hand, it avoids the continuous leakage of hot air, reduces the loss of excess energy of the low-temperature heat pump, thereby achieving energy-saving effects and improving the safety of the low-temperature heat pump during operation.
