All-plastic emulsion pump with good sealing performance

Abstract

The all-plastic emulsion pump with the good sealing performance comprises an installation assembly, a bottle opening, a bottle cap, a bottle opening ring, a bottle opening pin, a locking column, a pull block and a pull plate, the bottle cap is arranged outside the bottle opening, the bottle opening ring is fixed to the bottle opening, the bottle cap is provided with a through groove and a guide groove, and the through groove is communicated with the guide groove. The bottle opening pin is clamped with the through groove and the guide groove, a first limiting groove is formed in the bottle opening pin, a second limiting groove is formed in the bottle cap, and the locking column can be clamped with the second limiting groove. The emulsion pump has the advantages that the installation assembly and the sealing assembly are arranged, so that the emulsion pump is conveniently installed, sealing is guaranteed, the situation that due to the fact that the emulsion pump is fixed in a threaded connection mode, the installation accuracy is uncertain, and sealing is insufficient is avoided, the installation difficulty is lowered, and the sealing performance is improved; and better use experience is brought to a user.
