Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-3, a heating tube assembly with a crack-proof plug comprises a heating tube 1, the heating tube 1 includes a water inlet 11 and a water outlet 12, a vacuum tube 2 is disposed in the heating tube 1, a water flow channel 3 is disposed between the heating tube 1 and the vacuum tube 2, two ends of the vacuum tube 2 are respectively sealed by the crack-proof plug 4, a plurality of guide fins 41 are circumferentially disposed on the crack-proof plug 4, and the crack-proof plug 4 is connected to an inner wall of the heating tube 1 through the guide fins 41.

When the device is used, water enters the heating pipe 1 from the water inlet 11, then enters the water flow channel 3 through a plurality of water diversion flow channels formed by the flow guide fins 41 of the anti-expansion-cracking plug 4 and the heating pipe 1, and the heating pipe 1 and the vacuum pipe 2 heat the water in the water flow channel 3. Because water is shunted by the anti-cracking plug 4 when entering the heating pipe 1, even in a low-temperature environment, the water flow volume is increased, and the external part cannot be damaged by expansion. Meanwhile, the stability of the water flow channel 3 in the heating process of the heating pipe component is also ensured.

Specifically, the anti-cracking plug 4 comprises a plug part 42 and a flow guide part 43, the plug part 42 is connected with the inner wall of the vacuum tube 2, and the flow guide fins 41 are circumferentially arranged on the side surface of the flow guide part 43. Preferably, the number of the flow guide fins 41 is 4, which not only ensures the speed of water flow and does not influence the heating efficiency, but also effectively prevents the problem of large-area volume increase which may occur.

More specifically, the flow guide part 43 comprises a flow guide base 431 connected with the port of the vacuum tube 2 and a flow guide block 432 far away from the port of the vacuum tube 2, and the distance between the flow guide block 432 and the inner wall of the heating tube 1 is greater than the distance between the flow guide base 431 and the inner wall of the heating tube 1. In order to reduce the influence of the flow guiding fins 41 on the water velocity and to prevent the wear caused by the impact force due to the flow restriction. The area of the water diversion channel at the part of the diversion block 432 is larger than that of the water diversion channel at the part of the diversion base 431.

It will be appreciated by those skilled in the art that the diameter of the deflector base 431 is greater than the diameter of the inner wall of the vacuum tube 2 and less than the diameter of the outer wall of the vacuum tube 2. The diameter of the diversion base 431 is larger than that of the inner wall of the vacuum tube 2, so that water flow can be effectively prevented from entering the vacuum tube. And the diameter of the diversion base 431 is smaller than that of the outer wall of the vacuum tube 2, so that the volume in the water flow channel 3 is ensured when the heating tube is heated.

Further, the plug portion 42 and the flow guiding portion 43 are made of an elastic material. The plugging portion 42 and the flow guiding portion 43 may be made of silicone or rubber material. Preferably, the elastic material still has elasticity at minus 20 degrees, and the heating pipe is protected to the maximum extent. The material can generate certain deformation under stress, and gives larger flow passage space for water flow. But the stress generated by deformation is small, and the sealing of the expansion crack preventing plug 4 on the vacuum tube 2 cannot be influenced.

As shown in fig. 4-5, a hard block 421 is disposed in the plug portion 42, and one end of the hard block 421 is connected to the flow guide portion 43. In order to further enhance the sealing of the anti-cracking plug 4 to the vacuum tube 2 and to reduce the influence of heat transfer on the heating efficiency, the hard plug 421 is made of a different material from the anti-cracking plug 4, and a plastic with low elasticity, such as epoxy resin, can be used.

When the flow guide base is used, the deformation layer 422 is arranged on the side surface of the plug part 42, and the diameter of the deformation layer 422 is not smaller than that of the flow guide base 431. The embodiment is not provided with threads, the anti-cracking plug 4 is inserted into the vacuum tube 2, and the vacuum tube 2 is completely sealed through deformation of the deformation layer 422. The material of the deformation layer 422 may be identical to the plug portion 42.

Because the port is stressed greatly, the port of the vacuum tube 2 is prevented from deforming too much to cause water seepage. The deformation layer 422 is inclined to the axis at one end close to the flow guide part 43 to form an extrusion part 423, and the deformation layer 422 is further provided with an annular groove 424.

Further, in order to facilitate the actual installation and detection, the length of the deformation layer 422 is smaller than that of the hard block 421.

The one end that the water conservancy diversion portion 43 was kept away from to the deformation layer 422 set up the round platform shape and let the position portion 425, the one end that lets the position portion 425 be close to the deformation layer 422 unanimous with the diameter of deformation layer 422, let the position portion 425 and end cap portion 42 and deformation layer 422 cooperate sealed stifled piece 421. The positioning part 425 facilitates the installation of the anti-expansion plug 4, and also gradually increases the stress when the plug part 42 enters the inner wall of the vacuum tube 2, thereby reducing the loss possibly generated during the installation.

The utility model discloses a theory of operation is: firstly, the vacuum tube 2 is sealed by the anti-cracking plug 4, the yielding part 425 firstly enters the inner wall of the vacuum tube 2 and is gradually stressed and deformed until the deformation layer 422 completely enters the vacuum tube 2 to complete sealing. When the heating pipe assembly is used, water flow enters the heating pipe 1 through the water inlet 11, then enters the water flow channel 3 through a plurality of water diversion flow channels formed by the flow guide fins 41 of the anti-expansion-cracking plug 4 and the heating pipe 1, and the heating pipe 1 and the vacuum pipe 2 heat water in the water flow channel 3. Even under microthermal ambient condition, the water that gets into in the heating tube becomes ice, and the anti-cracking end cap at vacuum tube both ends produces deformation, and increase water inlet volume effectively avoids appearing the problem that rises bad appearance spare.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.

Although terms such as the heating pipe 1, the water inlet 11, the water outlet 12, the vacuum pipe 2, the water flow channel 3, the anti-cracking plug 4, the flow guide fin 41, the plug part 42, the flow guide part 43, the flow guide base 431, the flow guide block 432, the hard plug 421, the deformation layer 422, the extrusion part 423, the annular groove 424 and the receding part 425 are used more frequently, the possibility of using other terms is not excluded.
