In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "mounted / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] like Figure 1-3 As shown, the present invention provides a heating device for preventing automobile respirator from freezing and clogging, comprising:

[0030] Shell 1, which has an inlet and an outlet, wherein the oil-water-gas mixture enters from the inlet at the upper end of the shell and is discharged from the outlet pipe at the lower left end;

[0031] The heating element 2 is arranged in the housing 1, preferably installed inside the upper end of the channel through which the oil-water-gas mixture flows, and can effectively prevent the channel from freezing and clogging by heating the oil-water-gas mixture flowing through;

[0032] The heating element 2 is preferably a PTC heater and a silicone rubber heater.

[0033] Among them, the PTC heater is a positive temperature coefficient thermistor with the function of automatic temperature control and uniform automatic control of liquid evaporation. It is connected by the first PTC resistor element, the second PTC resistor element and the aluminum profile shell, and the aluminum profile shell is fixed to the plastic pot to form a cavity. This heater does not require a temperature control device and can effectively control the heating process to ensure safety and efficiency in use.

[0034] Silicone rubber heater is made of high and low temperature resistant, anti-corrosion, high insulation, aging resistant silicone rubber and non-silicone fiber cloth, imported foam rubber and other materials. This heater consists of three layers: inner lining, middle insulation layer and outer protective layer. It has good insulation effect and high and low temperature resistance. It also has high insulation performance and aging resistance, weather resistance, corrosion resistance and other characteristics, and has a long service life.

[0035] PTC heaters and silicone rubber heaters not only improve the performance and safety of the respirator, but also ensure its reliable operation in various environments.

[0036] A power supply head connecting rod, which is arranged in the housing 1 and is used to connect with the heating element 2; wherein the power supply head connecting rod includes a connecting rod a5, a connecting rod b6 and a connecting rod c7;

[0037] The temperature sensor 3 is arranged in the housing 1 and connected to the power head connecting rod, and is used for detecting the temperature in the housing and transmitting the detected temperature signal to the controller.

[0038] When the temperature sensor 3 detects that the temperature inside the shell is lower than the preset first temperature threshold, the controller controls the power head connecting rod to connect the power, and the heating element 2 starts heating. When the preset second temperature threshold is reached, the controller controls the power head connecting rod to disconnect from the power supply.

[0039] The heating element 2 is connected to the positive electrode through the terminal c10 and the connecting rod a5, and is connected to the negative electrode through the terminal b9 and the connecting rod b6;

[0040] The temperature sensor 3 has two legs, one connected to the terminal b9, and the other connected to the connecting rod c7 through the terminal a8.

[0041] In the present invention, the connecting rod a5, the connecting rod b6 and the connecting rod c7 are all provided with a first sealing ring 11 for radial sealing, and the connecting rod a5, the connecting rod b6 and the connecting rod c7 are all provided with a second sealing ring 12 for end face sealing. The first sealing ring 11 and the second sealing ring 12 can effectively prevent oil and water from leaking to the outside from the power plug through the combined sealing of radial direction and end face.

[0042] The connecting rod a5, the connecting rod b6 and the connecting rod c7 are used as electrical plugs for connecting to a power source and transmitting the signal of the temperature sensor 4 inside the housing 1 to an external controller for control.

[0043] Since the material of connecting rod a5, connecting rod b6 and connecting rod c7 is brass, which has a large difference in temperature linear expansion coefficient with the plastic material of shell 1, a gap will be generated between the connecting rod and shell 1 due to temperature changes, which will cause the oil and water inside the respirator to leak from the gap along the connecting rod to the outside. In order to prevent leakage, two seals are placed on each connecting rod, the first seal ring 11 is a radial seal, and the second seal ring 12 is an end face seal, which can ensure that temperature changes will not generate gaps and the respirator heater will not leak.

[0044] In the present invention, the power head connecting rod is fixed in the shell by means of glue injection 4.

[0045] On the other hand, the present invention also provides an automobile respirator, comprising the above-mentioned heating device.

[0046] In the present invention, the heating device is screwed to the automobile respirator body.

[0047] like Figure 4 As shown, in the present invention, the heating device is connected to the automobile respirator body through a hose.

[0048] The above are only preferred specific implementations of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and improved concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
