Reference numbers in the figures: 1. a cushion frame; 2. an air flow channel; 3. a gravity sensor; 4. a fan; 5. a cushion main body; 6. an air bag; 7. a vent hole; 8. a negative ion generator; 9. LED atmosphere lamp area.

Detailed Description

The embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways as defined and covered by the claims.

The utility model discloses an aspect provides a ventilation cushion, include: the cushion framework 1 is internally provided with an airflow channel 2; the gravity sensor 3 is connected with the cushion framework 1 and used for detecting the pressure applied to the cushion framework 1; the fan 4 is arranged at one end of the cushion framework 1 and used for supplying air to the airflow channel 2; and the controller is connected with the gravity sensor 3 and the fan 4, and the controller turns on the fan 4 when the pressure is greater than a first preset value or turns off the fan 4 when the pressure is less than a second preset value. Preferably, the number of the fans 4 is two, and the fans are symmetrically distributed.

Therefore, when a human body sits on the seat cushion, the gravity sensor 3 sends the detected pressure to the controller, the controller starts the fan 4, and then the wind flows in the airflow channel 2 and is blown out outwards, so that the aim of radiating heat for a user is fulfilled; when the human body leaves, the pressure detected by the gravity sensor 3 is reduced, and the controller automatically turns off the fan 4.

Since the technical scheme is used, the utility model discloses whether accessible gravity sensor response uses the cushion to realize opening this control to the automation of fan, it is more humanized, it is more convenient to use.

In one embodiment, preferably, the ventilated cushion further includes a cushion main body 5 mounted on the cushion frame 1, the cushion main body 5 includes a plurality of air bags 6, and a ventilation hole 7 provided between the plurality of air bags 6, and the ventilation hole 7 communicates with the air flow passage 2. Therefore, a ventilating heat dissipation channel can be formed between the air bags 6, and the wind blowing to the human body brings heat to be discharged out of the cushion along the heat dissipation channel, so that the thermal sensation of the human body is reduced. Therefore, a double-air-channel design can be formed through the channel between the internal airflow channel 2 and the air bag 6, the wind resistance is reduced, the wind circulation is more natural and smooth, and the noise is effectively reduced. The ventilation gap formed by the air bags on the bubble pad can enable air flow to pass through the buttocks and the legs of a human body more smoothly under the condition that a person sits on the bubble pad, so that a better heat dissipation effect is achieved; meanwhile, the air bag structure is arranged on the air bubble cushion, so that the comfort is greatly improved.

In another embodiment, preferably, the ventilated cushion further comprises an airbag cushion mounted on the cushion frame 1, so that wind can uniformly blow to a human body through the airbag cushion and carry heat.

Preferably, the ventilation cushion further comprises an anion generator 8 connected with the controller, and an outlet of the anion generator 8 is communicated with the airflow channel 2. Thus, the air is purified by the negative ion generator 8, the air is fresh, and the human body feels comfortable. Meanwhile, the controller can automatically control the start and stop of the negative ion generator 8 when the fan is automatically controlled to start and stop.

Preferably, ring flange fixed connection airflow channel 2 is passed through at anion generator 8's top, and the air after purifying through anion generator 8 passes through airflow channel 2 and gets into the cushion and ventilate, and the wind channel of optimization lets wind more unobstructed, and the rate of utilization of fan is higher, and the radiating efficiency is higher.

Preferably, the ventilation cushion further comprises a fan stepless speed regulator connected with the fan 4. The fan stepless speed regulator is provided with an adjusting knob. The speed of the fan is freely adjusted according to the comfort level by people, and the fan is more humanized.
