Description
Technical Field
[0001] This utility model application relates to the field of heater technology, specifically a waterproof and explosion-proof electric heater. Background Technology
[0002] An electric heater is an electrical appliance that uses electrical energy to achieve a heating effect. It is small in size, has high heating power, and is widely used. It adopts an intelligent control mode, has high temperature control accuracy, and can be networked with a computer. The core principle of the heater is energy conversion. The most widespread type is the electric heater, which converts electrical energy into heat energy by using the eddy current generated by the metal in the alternating magnetic field to generate heat and absorb heat. This converts electrical energy into light energy.
[0003] When an electric heater heats a liquid, if the instantaneous temperature is too high or the internal reaction is too violent and exceeds the control, the internal pressure is likely to increase. When the interface at both ends of the heater cannot withstand the internal pressure, water may overflow from the interface or even cause an explosion. Traditional heaters have poor waterproof and explosion-proof performance and cannot withstand sudden changes in internal pressure. Summary of the Invention
[0004] To address the problems of poor water spill prevention and explosion-proof performance of existing electric heaters during use, this invention provides a waterproof and explosion-proof electric heater to solve the aforementioned problems.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A waterproof and explosion-proof electric heater includes a heater tank, an inlet pipe, and an outlet pipe. The inlet pipe is fixed through the top of one side of the heater tank, and the outlet pipe is fixed through the bottom of the other side of the heater tank. An explosion-proof side box is fixed to the side of the inlet pipe. An explosion-proof side box is fixed to the side of the middle part of the heater tank. An exhaust port is opened at the center of the opposite side of the heater tank and the explosion-proof side box, and a sealing plug is fitted inside the exhaust port. A high-temperature resistant airbag is fixed to the outer surface of the explosion-proof side box outside the sealing plug, and the high-temperature resistant airbag is fitted inside the explosion-proof side box.
[0007] Furthermore, both ends of the heater tank outside the inlet pipe and outlet pipe are fixed with maintenance tank covers by flanges and bolts. A bracket is fixed symmetrically on the bottom surface of the heater tank, and a bracket is fixed in the middle of the bottom surface of the explosion-proof side box, with the bottom surface of the bracket being flush with the bottom surface of the bracket.
[0008] Furthermore, each of the sealing plugs is configured as a horizontally placed T-shape that mates with the exhaust port, the side of the explosion-proof side box near the heater tank is configured as an arc shape that mates with the heater tank, and the end of the sealing plug extending into the interior of the explosion-proof side box is configured as an arc shape that mates with the explosion-proof side box.
[0009] Furthermore, a support plate is slidably sleeved inside the explosion-proof side box outside the high-temperature resistant airbag, and a side push plate is slidably sleeved inside the explosion-proof side box outside the support plate. A connecting plate is symmetrically fixed between the support plate and the side push plate. Several supporting slide rods are equidistantly sleeved inside the side push plate between the two connecting plates. The end of each supporting slide rod away from the high-temperature resistant airbag is fixed to the inner wall of the explosion-proof side box. A second spring is sleeved on each supporting slide rod outside the side push plate, and the two ends of each second spring are respectively fixed to the side push plate and the inner wall of the explosion-proof side box.
[0010] Furthermore, the side push plate has several sliding holes equidistantly arranged inside to cooperate with the support slide rods, and each support slide rod is configured as a T-shaped rod placed horizontally.
[0011] Furthermore, the side push plate is fitted with steering plates on both the upper and lower sides away from the high-temperature airbag end, and the steering plates are slidably sleeved inside the explosion-proof side box. Several springs are fixed at equal intervals between the outer side of each steering plate and the upper and lower walls of the explosion-proof side box.
[0012] Furthermore, each of the steering plates is provided with a limiting plate on the side near the side push plate end, and the end of each limiting plate away from the side push plate is fixed to the upper and lower walls of the explosion-proof side box respectively. The side of each of the two steering plates near the side push plate is set to be inclined to cooperate with the side push plate.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. In this utility model, the pressure relief structure on the side breaks through the sealing plug when the internal pressure suddenly increases, so that the pressure is released in the high-temperature resistant airbag, thereby relieving the internal pressure. Moreover, the impact on the high-temperature resistant airbag can be reduced by squeezing the second spring during release. This solves the problem of poor water overflow and explosion-proof performance of existing electric heaters during use, and improves the safety of heater use.
[0015] 2. In this utility model, the inclined design of the upper and lower ends of the side push plate allows the upper and lower steering plates to move when pushed by the airbag, thereby changing the impact direction and avoiding the problem of displacement of the heater after being impacted, thus further improving the safety of the heater during use.

[0022] To make the purpose, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0023] Reference Figure 1 , Figure 2 and Figure 4A waterproof and explosion-proof electric heater includes a heater tank 1, an inlet pipe 2, and an outlet pipe 3. The inlet pipe 2 is fixedly connected to the top of one side of the heater tank 1, and the outlet pipe 3 is fixedly connected to the bottom of the other side of the heater tank 1. Both ends of the heater tank 1 outside the inlet pipe 2 and the outlet pipe 3 are fixed with inspection tank covers 4 via flanges and bolts. A bracket 1 5 is symmetrically fixed to the bottom surface of the heater tank 1. A bracket 2 7, with its bottom surface flush with the bottom surface of bracket 1 5, is fixed to the middle of the bottom surface of the explosion-proof side box 6. An explosion-proof side box 6 is fixed to the side of the inlet pipe 2, and an explosion-proof side box 6 is fixed to the middle side of the heater tank 1. The side box 6, the heater tank 1, and the explosion-proof side box 6 are all provided with exhaust ports 8 at the center of opposite sides, and the exhaust ports 8 are fitted with sealing plugs 9. Each sealing plug 9 is set as a horizontally placed T-shape to cooperate with the exhaust port 8. The side of the explosion-proof side box 6 near the heater tank 1 is set as an arc shape to cooperate with the heater tank 1. The end of the sealing plug 9 extending into the explosion-proof side box 6 is set as an arc shape to cooperate with the explosion-proof side box 6. A high-temperature resistant airbag 10 is fixed on the outer surface of the explosion-proof side box 6 outside the sealing plug 9. The high-temperature resistant airbag 10 is fitted inside the explosion-proof side box 6.
[0024] Specifically, when the internal reaction of the heater tank 1 is excessive, causing the gas pressure to increase to a level greater than the friction between the sealing plug 9 and the inner wall of the exhaust port 8, the sealing plug 9 is pushed into the high-temperature resistant gasbag 10 under the pressure. At the same time, the steam inside the heater tank 1 enters the high-temperature resistant gasbag 10. After the gas pressure inside the high-temperature resistant gasbag 10 increases, due to its high elasticity, the high-temperature resistant gasbag 10 deforms after the gas pressure increases. Under the limit of the explosion-proof side box 6, it gradually fills the interior of the explosion-proof side box 6, thereby reducing the pressure inside the heater tank 1.
[0025] As an optimization solution, such as Figure 3 and Figure 4As shown, a support plate 12 is slidably sleeved inside the explosion-proof side box 6 outside the high-temperature airbag 10. A side push plate 14 is slidably sleeved inside the explosion-proof side box 6 outside the support plate 12. Several sliding holes that cooperate with the support slide rods 15 are equidistantly opened inside the side push plate 14. Each support slide rod 15 is set as a horizontally placed T-shape. A connecting plate 13 is symmetrically fixed between the support plate 12 and the side push plate 14. Several support slide rods 15 are slidably sleeved inside the side push plate 14 between the two connecting plates 13. The end of each support slide rod 15 away from the high-temperature airbag 10 is fixed to the inner wall of the explosion-proof side box 6. A spring is sleeved on each support slide rod 15 outside the side push plate 14. Two springs 16 are fixed at both ends to the side push plate 14 and the inner wall of the explosion-proof side box 6, respectively. The upper and lower sides of the side push plate 14 away from the high-temperature airbag 10 are fitted with steering plates 17, and the steering plates 17 are slidably sleeved inside the explosion-proof side box 6. Each steering plate 17 is provided with a limiting plate 18 on the side near the side push plate 14. The end of each limiting plate 18 away from the side push plate 14 is fixed to the upper and lower walls of the explosion-proof side box 6, respectively. The side of the two steering plates 17 near the side push plate 14 is set to be inclined to cooperate with the side push plate 14. Several springs 11 are fixed at equal intervals between the outer side of each steering plate 17 and the upper and lower walls of the explosion-proof side box 6.
[0026] Specifically, when the high-temperature airbag 10 deforms, it pushes the support plate 12, causing the support plate 12 to drive the side push plate 14 to compress the second spring 16. The restoring force of the second spring 16 can offset part of the impact force, thereby reducing the impact force on the high-temperature airbag 10. At the same time as the side push plate 14 moves, it also pushes the steering plate 17 up and down, causing the steering plate 17 to compress the first spring 11 and slide inside the explosion-proof side box 6. The restoring force of the first spring 11 helps to offset part of the impact force, further achieving the explosion-proof effect and preventing internal water from overflowing through the gap between the maintenance tank cover 4 and the heater tank 1.
