A kind of spray pump head, which consists of a pump core (1), a middle cover (2), and a nozzle head (3). The upper end of the pump core is in contact with the nozzle head; the pump core includes a pump core body (11), an upper piston (12), a reverse thrust plug (13), and a sealing ring. The pump core body is a hollow drum with a multi-layer stepped structure. The pump core body is slidably matched with the upper piston and the reverse thrust plug, and the reverse thrust plug is limited between the pump core body and the upper piston; the reverse thrust plug and the lower half of the pump core body constitute the lower chamber, and the reverse thrust plug An elastic part is arranged below, a steel ball is arranged at the bottom of the elastic part, and the elastic part, the steel ball and the conical liquid inlet pipe at the bottom of the main body of the pump core constitute a one-way valve; it is characterized in that: the upper piston is formed between the reverse thrust plug and the upper piston. In the chamber, the center of the upper part of the reverse thrust plug is provided with a reverse thrust plug, the top of the reverse thrust plug is a cone, and the center of the upper piston is provided with a circular table, which cooperates with the cone of the reverse thrust column to form a reverse single valve; The center of the piston is provided with a connecting groove, the lower chamber and the upper chamber are connected through the connecting groove, and the end of the connecting groove is provided with a damping hole.
A spray pump
head is a very common accessory for liquid containers. It is used to press the liquid in the bottle to make the mixed fluid of air and liquid flow out from the small hole quickly. The thin tube rises up and flows out from the upper opening of the thin tube, and is impacted by the airflow, and diffuses in the air in the form of a spray to form a small particle air suspension.
A new type of spray pump mechanism", which includes a lock bottle cap, a pump body installation part is arranged at the upper end of the lock bottle cap, a pump chamber is arranged in the pump body installation part, and a liquid inlet is arranged at the lower end of the pump chamber. There are pump beads in the liquid port, an upper pump rod is arranged in the pump chamber, the upper end of the upper pump rod extends out of the pump chamber, a button is connected to the upper end of the upper pump rod, a liquid spray channel is arranged in the button, and a mist is arranged on the button. The fog point is connected with the liquid spray channel, a positioning ring platform is arranged on the lower outer wall of the upper pump rod, a locking cover is arranged on the upper end of the pump chamber, and a lower pump rod is movably connected in the upper pump rod, and the upper pump rod is connected with the upper pump rod. There is a suction plug between the lower pump rod, a secondary spring between the positioning ring platform and the upper end of the suction plug, a main spring between the button and the locking cover, and a pump chamber on the outside of the pump body mounting part. The outer convex connecting ring is provided with an outer cover on the outer casing of the outer convex connecting ring.
