Description

Technical Field

[0001] This utility model relates to the field of PTC ceramic semiconductor electric heating device production technology, and in particular to PTC ceramic semiconductor electric heating equipment. Background Technology

[0002] PTC ceramic semiconductor electric heating equipment is an electric heating device that uses positive temperature coefficient (PTC) thermistor ceramic material to achieve automatic constant temperature. It has advantages such as high efficiency and energy saving, safety and reliability, and long service life, and is widely used in homes, offices, bathrooms and other scenarios.

[0003] PTC ceramic semiconductor electric heating equipment mainly provides heating by connecting to electricity. However, when heating directly by electricity, it is not convenient to control the heat, which may lead to heat waste and economic losses. Furthermore, when the temperature is too high, it may cause safety accidents such as fires.

[0004] Therefore, how to provide PTC ceramic semiconductor electric heating equipment is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] One objective of this invention is to provide a PTC ceramic semiconductor electric heating device that, through a heating mechanism, can control the generated heat, thereby solving the problems mentioned in the background art.

[0006] According to an embodiment of the present invention, a PTC ceramic semiconductor electric heating device includes a PTC electric boiler body. Two cabinet doors are installed on one side of the PTC electric boiler body, and an LCD screen is fixedly installed on one side of each cabinet door. Both cabinet doors are connected to the PTC electric boiler body via hinges. The PTC electric boiler body has a heating mechanism inside, which includes an overheating seat, a first inner wire, a second inner wire, a connecting seat, a connecting shaft, and a ceramic semiconductor electric heating rod. Two overheating seats are fixedly installed on one side of the inner wall of the PTC electric boiler body. The inner wall of one of the overheating seats is fixedly installed with a first inner wire and a second inner wire. A connecting seat is fixedly installed on the side of the two overheating seats that are close to each other. Two connecting shafts are fixedly installed on the end of each connecting seat that is close to each other. A ceramic semiconductor electric heating rod is fixedly installed on the end of each connecting shaft that is close to each other.

[0007] As a preferred embodiment of this utility model: aluminum profile structural shafts connected to two connecting shafts are fixedly installed at the middle of both ends of the ceramic semiconductor electric heating rod, and PTC semiconductor ceramic sheets are provided on the outer ring of the aluminum profile structural shafts.

[0008] As a further preferred embodiment of this utility model: the outer ring of the PTC semiconductor ceramic sheet is provided with ceramic fiber cotton, and the outer ring of the ceramic fiber cotton is provided with a stainless steel shell.

[0009] As a further preferred embodiment of this utility model: the inner wall of the two overheat seats has a pipe fixing plate on one side, and a pipe channel is opened in the middle of the middle of the two pipe fixing plates.

[0010] As a further preferred embodiment of this utility model: two connecting plates are fixedly installed on one side of each of the two overheat seats, and a threaded shaft is threadedly connected to one side of each of the four connecting plates, and the threaded shaft is threadedly connected to the PTC electric boiler body.

[0011] As a further preferred embodiment of this utility model: an inlet pipe and an outlet pipe are fixedly installed on one side of the PTC electric boiler body, and the inlet pipe and the outlet pipe are both sleeved and connected to the pipeline channel.

[0012] The beneficial effects of this utility model are: The PTC electric boiler uses a ceramic semiconductor heating rod in its heating mechanism for electrical conduction and heating. The aluminum shaft conducts heat, which is then transferred to the PTC semiconductor ceramic sheet and ceramic fiber cotton for heat conduction and insulation. The stainless steel outer shell further provides insulation, thus insulating and conducting heat to the water in the connected pipes. Simultaneously, when current flows through the PTC semiconductor ceramic sheet, resistance heating occurs, increasing the temperature. As the temperature rises, the resistance of the PTC semiconductor ceramic sheet increases, thereby reducing the current and power, achieving automatic temperature regulation. This characteristic gives the PTC electric boiler an automatic temperature control function, preventing overheating and avoiding safety accidents such as fires caused by overheating.

An LCD screen 12 is fixedly installed on one side of each cabinet door 11. Both cabinet doors 11 are connected to the PTC electric boiler body 1 via hinges 15. The PTC electric boiler body 1 is equipped with a heating mechanism inside, which includes an overheat seat 2, a first inner wire 3, a second inner wire 4, a connecting seat 5, a connecting shaft 6, and a ceramic semiconductor electric heating rod 7. Two overheat seats 2 are fixedly installed on one side of the inner wall of the PTC electric boiler body 1. The first inner wire 3 and the second inner wire 4 are fixedly installed on the inner wall of each of the overheat seats 2. A connecting seat 5 is fixedly installed on the side of each of the two overheat seats 2 that are close to each other. Two connecting shafts 6 are fixedly installed on the side of each of the two connecting shafts that are close to each other. A ceramic semiconductor electric heating rod 7 is fixedly installed on the side of each of the two connecting shafts 6 that are close to each other. Both the first inner wire 3 and the second inner wire 4 can generate heat through electrical conductivity. The specifications of the first inner wire 3 and the second inner wire 4 are M12*1.25 inner wire and M5*10 wire respectively. At this time, the first inner wire 3 and the second inner wire 4 generate heat through electrical conductivity, and can conduct heat to the ceramic semiconductor electric heating rod 7 through the connecting seat 5 and the connecting shaft 6. At this time, the aluminum structure shaft 704 generates heat through electrical conductivity, and conducts heat and insulates through the PTC semiconductor ceramic sheet 703 and the ceramic fiber cotton 702. Then, it is insulated by the stainless steel shell 701, so as to insulate and conduct heat to the water in the pipe connected in the pipe channel 8 and achieve a warming effect.

[0020] refer to Figure 1 As shown in Figures 1, 2, and 3, aluminum profile shafts 704, which are connected to two connecting shafts 6, are fixedly installed at the middle of both ends of the ceramic semiconductor electric heating rod 7. The outer ring of the aluminum profile shaft 704 is provided with a PTC semiconductor ceramic sheet 703, the outer ring of the PTC semiconductor ceramic sheet 703 is provided with ceramic fiber cotton 702, and the outer ring of the ceramic fiber cotton 702 is provided with a stainless steel shell 701.

[0021] refer to Figure 1 As shown in Figures 1, 2, and 3, there are pipe fixing plates 9 on one side of the inner wall of the two overheating seats 2. Pipe channels 8 are opened in the middle of the two pipe fixing plates 9. Two connecting plates 16 are fixedly installed on one side of the two overheating seats 2. Threaded shafts 10 are threadedly connected to one side of the four connecting plates 16. The threaded shafts 10 are threadedly connected to the PTC electric boiler body 1. Water inlet pipes 14 and water outlet pipes 13 are fixedly installed on one side of the PTC electric boiler body 1. Water inlet pipes 14 and water outlet pipes 13 are sleeved and connected to the pipe channels 8.

[0022] Working principle: By installing connecting pipes in the inlet pipe 14 and outlet pipe 13 respectively, the first inner thread 3 and the second inner thread 4 can conduct heat through electrical conductivity, and can conduct heat to the ceramic semiconductor heating rod 7 through the connecting seat 5 and the connecting shaft 6. At this time, the aluminum structure shaft 704 conducts heat through electrical conductivity, and conducts heat and insulates through the PTC semiconductor ceramic sheet 703 and ceramic fiber cotton 702, and then through the stainless steel shell 701 for insulation. Thus, the water in the pipe connected in the pipeline channel 8 can be insulated and heated. When the current passes through the PTC semiconductor ceramic sheet 703, it generates heat through resistance and the temperature rises. As the temperature rises, the resistance value of the PTC semiconductor ceramic sheet 703 will also increase, thereby reducing the current and power, achieving the purpose of automatic temperature regulation. This characteristic makes the PTC electric boiler body 1 have an automatic constant temperature function, and will not overheat, avoiding safety accidents such as fire caused by overheating.
