Description

Technical Field

[0001] The utility model relates to the technical field of air intake temperature control devices for an automobile, in particular to an air intake temperature control device for an automobile air filter. Background Art

[0002] In the prior art, the intake air quality and intake air temperature of the engine are crucial. The intake air quality can ensure that the engine can operate normally, while the intake air temperature can ensure whether the engine can operate in the best working state. Too high or too low intake air temperature has a great impact on the operation of the engine. In the prior art, if the engine intake air temperature is too high, it is generally solved by cooling with an intercooler, and if the engine intake air temperature is too low, it can be solved by electric heating. This application document mainly improves the electric heating temperature control structure of the engine intake air temperature that is too low.

[0003] In the prior art, an electric heating grille is generally added behind the air filter inside the intake duct to ensure the intake temperature when the engine is just started in a low-temperature environment. In this way, the electric heating grille is always arranged behind the air filter inside the intake duct. If the heating wires inside the electric heating grille are designed to be more and denser, then regardless of whether the electric heating grille needs to be used, the dense electric heating grille will occupy a part of the space of the air inlet, which is easy to affect the air intake effect of the air inlet. Therefore, in order to address this problem, an improved automobile air filter intake temperature control device is needed. Utility Model Content

[0004] The utility model aims to provide an automobile air filter intake temperature control device to solve the problems raised in the above-mentioned background technology.

[0006] Preferably, a servo motor is fixedly provided on the upper end of the valve body, and a power output shaft end of the servo motor is transmission-connected to a rotating shaft where the control valve core is located, so that the control valve core can be conveniently driven to rotate by the servo motor.

[0007] Preferably, the flow channel is T-shaped, and the T-shaped flow channel can be in different rotation states so that the air can flow in different directions.

[0008] Preferably, a filter element is fixedly provided at one end of the air intake pipe, through which the air can be filtered to ensure the cleanliness of the intake air.

[0009] Preferably, a temperature detection device is fixedly provided on the air intake pipe between the filter element and the valve body.

[0010] Preferably, a connecting manifold is fixedly provided at one end of the air intake pipe away from the filter element, and the air intake pipe and the air intake port of the engine can be conveniently connected through the connecting manifold. Of course, a throttle valve and other structures should be installed at the connection between the air intake pipe and the connecting manifold, but this is not the focus of protection of this application document.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model does not need to heat the intake air temperature.

(The flow channel state is as follows Figure 4 As shown), at this time, the air enters the front end of the air intake pipe through the filter element and then flows through the T-shaped flow channel directly into the rear end of the air intake pipe. In this way, when the heating device is not needed, the entire air flow can be guaranteed to be unobstructed, so that the air intake pipe maintains the best conduction state, thereby improving the air intake effect.

[0013] 2. The utility model is easy to use as a whole. The air intake and heating control can be completed by only driving the control valve core to rotate 90 degrees through the servo motor. It is easy to use and has a simple structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] A servo motor 8 is fixedly disposed on the upper end of the valve body 2. The power output shaft end of the servo motor 8 is transmission-connected to the rotating shaft where the control valve core 6 is located. The servo motor 8 can conveniently drive the control valve core 6 to rotate.

[0022] The flow channel 7 is T-shaped, and the air can flow in different directions through the T-shaped flow channel 7 in different rotation states;

[0023] A filter element 9 is fixedly provided at one end of the air intake pipe 1, through which the air can be filtered to ensure the cleanliness of the intake air;

[0024] The air intake pipe 1 is fixedly provided with a temperature detection device 10 between the filter element 9 and the valve body 2. The temperature detection device 10 can detect the intake air temperature at any time, so as to judge whether the heating device 5 needs to be used; when the heating device 5 needs to be used, the servo motor 8 drives the control valve core 6 to rotate, so that the T-shaped flow channel 7 in the control valve core 6 connects the branch pipe 3 and the air intake pipe 1 together (the state of the flow channel 7 is as follows Figure 3 As shown), at this time, after the air passes through the filter element 9 and enters the front end of the air intake pipe 1, it will flow into the branch pipe 3 through the T-shaped flow channel 7, and then pass through the branch pipe 3 flow channel 7 to the rear end of the air intake pipe 1. During the flow process in the branch pipe 3, it can contact with the heating device 5 to increase the temperature and ensure that the intake temperature is within the appropriate threshold range;

[0025] If the intake air temperature does not need to be heated, the servo motor 8 drives the control valve core 6 to rotate, so that the T-shaped flow channel 7 in the control valve core 6 blocks the branch pipe 3 and the air intake pipe 1 (the state of the flow channel 7 is as follows Figure 4 As shown), at this time, the air enters the front end of the air intake pipe 1 through the filter element 9, and then flows through the T-shaped flow channel 7 to directly enter the rear end of the air intake pipe 1. In this way, when the heating device 5 is not needed, the air intake pipe 1 can be kept in the best conduction state, thereby improving the air intake effect;

[0026] A connecting manifold 11 is fixedly provided at one end of the air intake pipe 1 away from the filter element 9, and the air intake pipe 1 and the air intake port of the engine can be conveniently connected through the connecting manifold 11.

Therefore, this application document will no longer introduce the installation position of the throttle valve in detail.

[0027] Working principle: When using this device, the device can control whether the intake air of the engine passes through the heating device 5 by controlling the rotation angle of the valve core 6. The principle is as follows: the temperature of the intake air can be detected at any time by the temperature detection device 10, so as to judge whether the heating device 5 needs to be used; when the heating device 5 needs to be used, the servo motor 8 drives the control valve core 6 to rotate, so that the T-shaped flow channel 7 in the control valve core 6 connects the branch pipe 3 and the air intake pipe 1 together (the state of the flow channel 7 is as follows Figure 3 As shown), at this time, after the air passes through the filter element 9 and enters the front end of the air intake pipe 1, it will flow into the branch pipe 3 through the T-shaped flow channel 7, and then pass through the branch pipe 3 flow channel 7 to the rear end of the air intake pipe 1. During the flow process in the branch pipe 3, it can contact with the heating device 5 to increase the temperature and ensure that the intake temperature is within the appropriate threshold range;

[0028] If the intake air temperature does not need to be heated, the servo motor 8 drives the control valve core 6 to rotate, so that the T-shaped flow channel 7 in the control valve core 6 blocks the branch pipe 3 and the air intake pipe 1 (the state of the flow channel 7 is as follows Figure 4 As shown), at this time, the air enters the front end of the air intake pipe 1 through the filter element 9 and then flows through the T-shaped flow channel 7 to directly enter the rear end of the air intake pipe 1. In this way, when the heating device 5 is not needed, the entire air flow can be guaranteed to be unobstructed, so that the air intake pipe 1 maintains the best conduction state, thereby improving the air intake effect;

[0029] The overall use process of the device is convenient. The air intake and heating control can be completed by only driving the control valve core 6 to rotate 90 degrees through the servo motor. This is convenient to use and has a simple structure. The heating device 5 of the device is a resistance heating wire bent in a serpentine shape.
