All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

It should be noted that, in this document, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation. The inclusion of an element as defined by the phrase "comprising one does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises an element.

Referring to fig. 1-3, embodiments of the present utility model are described in detail.

Examples: referring to fig. 1, the oil drip bottle with a backflow structure comprises an oil drip bottle body 1, an oil drip bottle opening 2 is formed in the upper portion of the oil drip bottle body 1, the oil drip bottle opening 2 is covered by an oil drip bottle cover 3, an oil drip pipe 4 is vertically arranged on the upper portion of the center of the oil drip bottle cover 3, the oil drip pipe 4 is of a conical structure, an oil drip port 5 is formed in the upper end of the oil drip pipe 4, and the oil drip port 5 is covered by an oil drip cover 6.

In this embodiment, referring to fig. 2, the lower end of the oil drop tube 4 is fixedly connected with the center of the outer surface of the oil drop bottle cap 3 and the inner cavity is communicated, the outer surface of the upper portion of the oil drop bottle cap 3 is an oil return inclined surface 9 with a peripheral high outer ring and a concave middle portion, an oil return hole 10 is formed in the root of the outer edge of the joint of the lower end of the oil drop tube 4 and the oil return inclined surface 9 of the oil drop bottle cap 3, and a one-way valve 11 is arranged on the oil return hole 10.

When the oil drip bottle is used, oil leaked from the oil drip opening 5 on the oil drip bottle can flow downwards into the oil return inclined plane 9 along the oil drip pipe 4, flow into the root of the joint of the oil drip pipe 4 and the oil return inclined plane 9 under the inclination action of the oil return inclined plane 9, and then flow into the oil drip bottle from the oil return hole 10, so that the problems that the environmental sanitation, the cleaning inconvenience and the oil waste are influenced due to the fact that the oil flowing out of the oil drip opening flows to the bottle body along the bottle or falls onto equipment and a table can be effectively prevented.

In this structure, through being equipped with check valve 11 on oil gallery 19, the setting of check valve 11 can make the outside oil liquid that retrieves flow into the oil drip bottle through oil gallery 10 in, and the fluid in the oil drip bottle can not follow oil gallery 10 when the bottle is invertd to can prevent the oil drip bottle when using and invert and its inside fluid problem that flows from the oil gallery.

In one embodiment, the check valve 11 may be a check valve structure commonly used in the art.

In an embodiment, referring to fig. 3, the check valve 11 may also have a structure including a check valve housing 12, where the check valve housing 12 is a conical cylinder structure with a small diameter at an upper end and a large diameter at a lower end, the check valve housing 12 has a small diameter and an opening at an upper end and is fixedly connected with an edge of an inner side opening of the oil return hole 10 coaxially, a supporting hole plate 14 is fixed at a large diameter lower end of the check valve housing 12, and a valve ball 13 is disposed inside the check valve housing 12.

The structure uses the principle that: when the oil dropping bottle is erected after being used, oil leaked from the oil dropping opening 5 on the oil dropping bottle flows downwards into the oil return inclined plane 9 along the oil dropping pipe 4, flows into the root of the joint of the oil dropping pipe 4 and the oil return inclined plane 9 under the inclination action of the oil return inclined plane 9, and then flows into the oil dropping bottle from the oil return hole 10. At this time, the valve ball 13 falls on the supporting orifice plate 14 with a large diameter at the lower part of the check valve housing 12 due to the action of gravity, the valve ball 13 is not closely attached to the check valve housing 12, and the oil can flow down along the gap between the valve ball 13 and the check valve housing 12 and flow into the bottle through the hole on the supporting orifice plate 14. When the oil dropping bottle is used, the oil dropping bottle is inverted, and the gravity valve ball 13 falls on the small diameter end of the check valve shell 12 and is clung to the circumference of the inner surface of the check valve shell 12, so that a sealing effect is generated, and oil in the oil dropping bottle can be prevented from flowing out from the oil return hole.

Preferably, the support orifice plate 14 is made of a mesh plate.

Preferably, the supporting hole plate 14 is formed by uniformly forming a plurality of holes in a plate.

In an embodiment, the oil drop cap 6 is connected with a connecting rope 7, one end of the connecting rope 7 is connected with the oil drop cap 6, the other end of the connecting rope 7 is connected with a connecting ring 8, and the connecting ring 8 is movably sleeved outside the oil drop bottle mouth 2.

The utility model has simple structure and convenient manufacture, can be directly added on the existing oil dropping bottle, and has low manufacturing cost.
