Description

Deodorization device for passenger car seats

The utility model relates to a deodorizing device for passenger car seats, in particular to a foot ventilation system under the seat.

At present, fans are commonly used in passenger car seat ventilation systems to control the airflow inside the compartment. The airflow mainly flows along the longitudinal direction of the compartment. Fully-enclosed window structures are commonly used in mid-to-high-end passenger cars, which cannot effectively control the dispersion of odors.

The purpose of the utility model is to provide a kind of deodorizing and ventilating device that can effectively replace the seat in the lower part of the compartment.

Another purpose of the utility model is to arrange a ventilating branch pipeline in the washroom of a long-distance bus to keep the air in the washroom fresh.

In order to achieve the above-mentioned purpose, the seat deodorizing device of the present utility model includes the ventilation branch pipe, the suction main pipe and the exhaust fan in the lower half of the seat, and its characteristics are: the ventilation branch pipe is installed under the passenger seat, An appropriate amount of suction holes is set in the air branch pipe, and the ventilation branch pipe is connected with the suction main pipe to discharge the air out of the compartment. In this way, air circulation from top to bottom can be realized inside the compartment, and the air inside the compartment can be effectively exhausted.

In addition, there are generally toilets in long-distance passenger vehicles, and the smell is particularly serious. A ventilation branch pipe is installed in the toilet to connect with the suction main pipe of the compartment, so that the smell of the toilet can be replaced.

The utility model has the advantages of:

1. The structure is simple, reliable and easy to install;

2. It can ensure the directional circulation of the air in the passenger's foot area under the condition of limited air exchange,

Prevent odor from spreading.

3. Due to the fixed-point layout of the suction port, it has an ideal effect.

Below in conjunction with accompanying drawing, structure, technical characterictic of the present utility model are described further.

Description of drawings:

Fig. 1 is the structural schematic diagram of the utility model.

Fig. 2 is a schematic diagram of ventilation in the bathroom of the utility model.

Example:

The seat deodorizing device of the present utility model comprises the ventilation branch pipe 4 of the lower half of the seat, the suction pipe 3 and the air extractor (not shown in the figure), and is characterized in that the ventilation branch pipe of the lower half of the passenger seat 4. Adopt up and down to be screwed with the seat 1 and the compartment floor 6, and can be adjusted left and right to move the air exchange branch pipe 4 with a hollow in the middle (shown in the enlarged cross-section of Figure 1), and several air suction pipes are arranged on both sides of the middle hollow Holes 5, one end of the ventilation branch pipe 4 are connected with the suction main pipe 3, and the suction main pipe 3 is connected with the exhaust fan, and an air filter is arranged at the joint.

During work, the air in the compartment is extracted by the exhaust fan, and the air enters the suction main pipe 3 through the suction hole 5 of the ventilation branch pipe 4 under the passenger seat, and then passes through the air filter (not shown) to the exhaust fan. Exhaust the peculiar smell in the car from the car. The exhaust fan is placed in the engine compartment, powered by the vehicle, and controlled manually.

In addition, a toilet 7 is generally provided in a long-distance bus, and a row of ventilating branch pipes can be arranged in the toilet 7 to connect with the suction main pipe 3, so that the smell and smell of the toilet can be replaced.

Claims (1)

1, a kind of seat deodorizing device comprises the ventilation arm of seat lower part, take a breath house steward and air suctiton ventilator, it is characterized in that:

The ventilation arm of seat lower part is respectively established several suction holes in the intermediate hollow both sides, and an end of ventilation arm is connected with air suction main, and air suction main is connected with air pump, is provided with air scrubber in the junction.
