Embodiment Construction

[0026] The present invention will be further described below in conjunction with accompanying drawing description and specific embodiment:

[0027] Such as Figures 1 to 6 The shown leak-proof ventilation structure includes a pump chamber 1, a ventilation hole 2 is arranged on the side wall of the upper end of the pump chamber 1, a swivel seat 3 is arranged in the pump chamber 1, and the swivel seat 3 is arranged on the side wall of the pump chamber 1. The outer wall of the seat 3 is sealed with the inner wall of the pump chamber 1, and the ventilation hole 2 is arranged on the pump chamber 1 corresponding to the outer wall of the rotary seat 3. The slotted hole 4 is provided with an upper pump rod 5 inside the rotary seat 3, and the outer wall of the rotary seat 3 and the upper pump rod 5 is sealed. Thereby, the curved mouth mechanism 6 that makes the slot 4 communicate with or block the ventilation hole 2 .

[0028] In the present invention, a positioning mechanism 7 is pr...

Abstract

The invention discloses a leak-proof ventilation structure. The leak-proof ventilation structure is characterized by comprising a pump chamber, wherein a ventilation hole is formed in the side wall of the upper end of the pump chamber, a rotary base is arranged in the pump chamber, the outer wall of the rotary base and the inner wall of the pump chamber are arranged in a sealed mode, the ventilation hole is formed in the portion, corresponding to the outer wall of the rotary base, of the pump chamber, a slot capable of being communicated with the ventilation hole is formed in the rotary base, an upper pump rod is arranged in the rotary base, the rotary base and the outer wall of the upper pump rod are arranged in a sealed mode, and the upper pump rod is connected with a bent nozzle mechanism which can drive the rotary base to rotate to enable the slot and the ventilation hole to be communicated or separated. The leak-proof ventilation structure aims to overcome the defects in the prior art and is simple, good in ventilation effect and capable of effectively preventing liquid leakage. The invention also aims at providing an emulsion pump with the leak-proof ventilation structure.

Description

technical field [0001] The invention relates to a leak-proof ventilation structure, and also relates to an emulsion pump with a leakage-proof ventilation structure. Background technique [0002] Because of its exquisite design and convenient use, the lotion pump has been widely used in daily chemical and pharmaceutical industries. However, the existing lotion pump has many parts, complex structure, difficult manufacture, high production cost, and due to the defects in the design of the existing lotion pump, its ventilation is not smooth, thereby seriously affecting the use effect of the lotion pump. Sometimes there will be leakage. Can not meet the needs of users. [0003] Therefore, the existing ventilation structure and the lotion pump all need to be further improved. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a ventilation structure with simple structure, good ventilation effect...
