Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.
[0023] Please refer to Figures 1-5 The present application provides a technical scheme: a crankcase ventilation pipe with self-heating function, which comprises a pipe body 1, the outer side of the pipe body 1 is sleeved with a sleeve 2, one end of the sleeve 2 is provided with a water storage cylinder 3, one side of the water storage cylinder 3 and located on the outer wall of the sleeve 2 is provided with a trace water pump 4, at the same time, the outer wall of the water storage cylinder 3 is provided with a water inlet 6, the water outlet of the trace water pump 4 is fixedly provided with a water supply pipe 5, and the outer wall of the pipe body 1 is provided with a spiral groove 11, the inside of the spiral groove 11 is provided with a heat pipe 7, and the water supply pipe 5 is communicated with the heat pipe 7; one side of the water storage cylinder 3 is provided with a water inlet hole 31 and a drain hole 32, the water inlet of the trace water pump 4 is connected with the water inlet hole 31, the other end of the heat pipe 7 is connected with the drain hole 32, and the inner wall of the water storage cylinder 3 is provided with a heating wire 33 and a temperature sensor 8.
[0024] Through the pipe body 1 and the sleeve 2, the heat pipe 7 can be installed, and the pipe body 1 can be reinforced. Since one end of the sleeve 2 is provided with the water storage cylinder 3, one side of the water storage cylinder 3 and located on the outer wall of the sleeve 2 is provided with the trace water pump 4, water is added into the water storage cylinder 3, at this time, the heating wire 33 and the temperature sensor 8 are powered by an external power supply, so that the heating wire 33 heats the water on the inner wall of the water storage cylinder 3, and the temperature sensor 8 detects the temperature of the water. When the water temperature is appropriate, the trace water pump 4 is started to drive the water in the water storage cylinder 3 to flow to the water supply pipe 5 and the heat pipe 7, and finally flows into the water storage cylinder 3 through the heat pipe 7, thereby uniformly heating the pipe body 1 and avoiding icing of the pipe body 1 in a low-temperature environment.
[0025] Please refer to Figure 2 , Figure 4 The inner side of the sleeve 2 is provided with a temperature insulation layer 21, and the heat pipe 7 is located on the inner wall of the sleeve 2. The heat pipe 7 is spiral-shaped, and the heat pipe 7 is installed in the inside of the spiral groove 11.
[0026] The heat pipe 7 can be installed through the sleeve 2. Since the inner side of the sleeve 2 is provided with the temperature insulation layer 21, the temperature insulation layer 21 can block heat, preventing heat from volatilizing outward from the sleeve 2. Since the heat pipe 7 is spiral-shaped, the spiral shape can increase the length of contact with the pipe body 1 and the heat transfer area, thereby effectively transferring heat to the pipe body 1, ensuring that the pipe body 1 can uniformly and quickly reach the required temperature.
[0027] Please refer toFigure 1 、 Figure 5 The pipe body 1 comprises an inner pipe 101, the outer wall of the inner pipe 101 is provided with a waterproof layer 102, the outer side of the waterproof layer 102 is provided with a heat conduction layer 103, and the outer side of the heat conduction layer 103 is provided with a pressure-resistant layer 104.
[0028] By arranging the waterproof layer 102 on the outer side of the inner pipe 101 in the pipe body 1, water in the pipe body 1 can be prevented from leaking from the inner pipe 101 to corrode the heat pipe 7, and by the heat conduction layer 103, the heat of the heat pipe 7 can be transmitted to the inner pipe 101 to rapidly heat the inner pipe 101 and improve the heating rate. Meanwhile, by the pressure-resistant layer 104, the overall structural strength of the pipe body 1 can be enhanced to resist corrosion from the external environment and corrosion of the inner pipe 101 by the internal medium, thereby prolonging the service life of the pipe body 1.
[0029] Referring to Figure 1 、 Figure 3 The inner wall of the water storage cylinder 3 is filled with a heat preservation layer, the heating wire 33 is in a ring shape, the heating wire 33 and the temperature sensor 8 are both installed in the inner cavity of the water storage cylinder 3, one end of the water supply pipe 5 is connected with the water outlet of the micro water pump 4, the other end of the water supply pipe 5 is fixedly connected with the heat pipe 7, and the other end of the heat pipe 7 is connected with the pipe hole 32.

Since the inner wall of the water storage cylinder 3 is filled with a heat preservation layer, the heat preservation layer can reduce heat loss in the water storage cylinder 3.
[0031] In operation, the pipe body 1 and the sleeve 2 can not only install the heat pipe 7, but also reinforce the pipe body 1. Since one end of the sleeve 2 is provided with the water storage cylinder 3, and the micro water pump 4 is installed on one side of the water storage cylinder 3 and located on the outer wall of the sleeve 2, water is added into the water storage cylinder 3. At this time, the heating wire 33 and the temperature sensor 8 are powered by an external power supply to heat the water on the inner wall of the water storage cylinder 3, and the temperature sensor 8 detects the temperature of the water. When the water temperature is appropriate, the micro water pump 4 is started to drive the water in the water storage cylinder 3 to flow to the water supply pipe 5 and the heat pipe 7, and finally flows into the water storage cylinder 3 through the heat pipe 7, thereby uniformly heating the pipe body 1 to avoid icing of the pipe body 1 in a low-temperature environment.
[0032] The heat pipe 7 is installed through the sleeve 2. The sleeve 2 is provided with a temperature insulation layer 21 on the inner side, so that the temperature insulation layer 21 can block heat and prevent heat from volatilizing outward from the sleeve 2. In addition, the heat pipe 7 is in a spiral shape, which can increase the length and heat transfer area in contact with the pipe body 1, so as to effectively transfer heat to the pipe body 1.
[0033] The inner pipe 101 in the pipe body 1 is provided with a waterproof layer 102 on the outer side, which can prevent water in the pipe body 1 from leaking from the inner pipe 101 and eroding the heat pipe 7. In addition, the heat pipe 7 can transmit heat to the inner pipe 101 through the heat conduction layer 103, so as to quickly heat the inner pipe 101 and improve the heating rate. In addition, the anti-pressure layer 104 can enhance the overall structural strength of the pipe body 1, so as to resist the erosion of the external environment and the corrosion of the inner pipe 101 by the internal medium, thereby prolonging the service life of the pipe body 1.
[0034] The heating wire 33 and the temperature sensor 8 are installed through the water storage cylinder 3. One end of the water supply pipe 5 is connected with the water outlet of the micro water pump 4, the other end of the water supply pipe 5 is fixedly connected with the heat pipe 7, and the other end of the heat pipe 7 is connected with the drain pipe hole 32. The water is heated by the heating wire 33, the micro water pump 4 flows the hot water into the water supply pipe 5, the heat pipe 7 and the water storage cylinder 3, forms a circulating flow, and uniformly heats the pipe body 1 to avoid freezing of the pipe body 1 in a low temperature environment. In addition, the temperature sensor 8 can monitor the temperature of the inner wall of the water storage cylinder 3. In addition, the inner wall of the water storage cylinder 3 is filled with a heat preservation layer, which can reduce the heat loss in the water storage cylinder 3.
[0035] In summary, the device can uniformly heat the pipe body 1 by the micro water pump 4, the water supply pipe 5, the heat pipe 7 and the heating wire 33 installed in the water storage cylinder 3, so as to avoid freezing of the pipe body 1 in a low temperature environment.
