New detachable refillable spray bottle

Abstract

The invention relates to the technical field of spraying bottles for containing liquid, in particular to a novel detachable and refillable liquid spraying bottle. The whole spraying bottle comprises a bottle body and a bottle bottom which are detachably connected through an integral valve seat. Positioning ribs, a seal groove and concave-convex toothed structures are disposed on the outer wall of the valve seat and connected with the bottle body. Threads are disposed on the outer wall of the valve seat and connected with the bottle bottom. A valve element is inserted in the inner cavity of the valve seat. The inner cavity of the valve seat is matched with the outer contour of the valve element and of an overall asymmetrical structure. The valve element can be inserted into the inner cavity of the valve seat at an only angle. A positioning device is disposed at the top end of the valve element and used for positioning an inner cavity spring. The overall asymmetrical structure of the inner cavity of the valve seat and the valve element is characterized in that one side of a contour line is a circular edge, and the other side thereof is a linear edge with an arc angle. The liquid spraying bottle has the advantages that the liquid spraying bottle is convenient to carry, convenient to demount and clean, good in airtightness and simple in production process, following rotation can be prevented, circulating refilling and repeated using can be achieved, and odor tainting of different gases is avoided.

Description

technical field [0001] The invention relates to the technical field of liquid-filled spray bottles, in particular to a novel detachable and refillable liquid spray bottle. Background technique [0002] Existing refillable liquid spray bottles are usually integrated, with a bayonet nozzle assembly, an inner bottle and other components inside the shell, and the liquid filling structure is located at the bottom or side of the inner bottle, which cannot be disassembled and is inconvenient to clean, which leads to When different liquids need to be filled, various smells in the inner bottle are mixed together, resulting in peculiar smell. [0003] Because the inside of the liquid spray bottle is mainly filled with liquid, it is necessary to prevent liquid leakage, and the bottle body has high requirements on sealing performance, so existing enterprises seldom produce and use detachable structures. [0004] In the prior art, the invention patent of another patent notification numb...

AI Technical Summary

Problems solved by technology

In the actual implementation of this patent, there are three very important problems. One is that when the lower cap is unscrewed, the bottom of the bottle and the body of the bottle will also rotate together, resulting in loosening, unable to form a good seal, and prone to liquid leakage.

The second is the sealing structure involved in the liquid filling and exhaust assembly: the liquid inlet seal between the liquid inlet and the liquid inlet channel, the gasket at the liquid inlet, the exhaust port seal at the exhaust channel and The sealing rings located in the first installation hole and the second installation hole respectively, the overall size of the valve core for installing these sealing gaskets and sealing rings is only 3.5mm in side length and 6mm in height, and the largest of these sealing gaskets and sealing rings is only 3.5mm in length. mm, width 2mm, thickness 1.5mm, and made of soft silica gel, it is difficult to operate manually and by machine. It is difficult to install the sealing ring into the place where it needs to be sealed, which makes the production process complicated and the product quality serious. Unstable, very low reliability

The third is that consumers are not professional technicians. As long as the assembly direction and angle are slightly ignored during the dismantling and washing process, the sealing and liquid-filling functions will fail, and consumers will easily lose confidence in product quality.
