Abstract
A foaming device comprises a valve body, a pump, and a self-suction spray head. The valve body comprises a water inlet port, a liquid inlet port, a mixing cavity, and a liquid outlet port. Each of the water inlet port, the liquid inlet port, and the liquid outlet port is in communication with the mixing cavity, and an input end of the pump is connected to the liquid outlet port to enable the mixing cavity to generate a negative pressure to suck water and foaming agent respectively from the water inlet port and the liquid inlet port for mixing. The self-suction spray head is connected to an output end of the pump, and the self-suction spray head comprises a first air inlet hole and a spray hole to enable mixed liquid to be mixed with air to produce foam to be sprayed out.
