the utility model provides a wash-bottle is used in laboratory that is used for perpendicular washing, includes bottle lid, body, nozzle and flushing pipe, the bottle lid with the body is connected, the flushing pipe connect in the bottle lid is gone up and is stretched into in the bottle lid, the nozzle is located on the bottle lid and with the flushing pipe intercommunication, wherein the flushing pipe end is equipped with the straw that extends to the body bottom, and this straw is less than downside bore width by upside bore width, the downside of straw is equipped with the breach. In order to achieve the purpose of small residual quantity, the suction pipe extends to the bottom of the bottle body through the suction pipe which is arranged at the tail end of the flushing pipe and is small at the top and large at the bottom, the horn-shaped design is utilized, even if the liquid level in the bottle drops to be close to the bottom of the bottle, the suction pipe can be kept to have a large contact area with liquid, and finally the suction pipe is attached to the bottom and is used for the liquid in the bottle to flow through the notch, so after the bottle body is pinched by hand, the liquid is pressed from the notch to the flushing pipe by air pressure and is sprayed out through the nozzle, the suction pipe attached to the bottom can effectively discharge water when a small amount of water is in the bottle, the residual quantity of the washing bottle is small, and the working efficiency is increased.

In some embodiments, a U-shaped return bend which is concave downwards is further arranged between the nozzle and the bottle cap.

In some embodiments, the nozzle is in threaded connection with the return bend.

In some embodiments, the nozzle is a mist nozzle.

In some embodiments, the straw is made of silica gel.

In some embodiments, the bottle cap and the bottle body are screwed and fastened in a rotating manner, and a sealing ring is arranged between the bottle cap and the bottle body.

In some embodiments, the underside of the straw is provided with a notch.

In some embodiments, the return bend is further provided with a regulating device for regulating the output volume, close to the nozzle.

Drawings

In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings used in the description of the embodiments will be briefly described below.

FIG. 1 is a first schematic structural diagram of the present invention;

fig. 2 is an enlarged view of fig. 1 at a.

Detailed Description

In order to make the technical problems, technical solutions and advantageous effects solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and do not limit the utility model.

Referring to fig. 1 to 2, the utility model provides a laboratory wash bottle for vertical washing, which comprises a bottle cap 1, a bottle body 2, a nozzle 3 and a washing pipe 4, wherein the bottle cap 1 is connected with the bottle body 2, the washing pipe 4 is connected to the bottle cap 1 and extends into the bottle cap 1, the nozzle 3 is arranged on the bottle cap 1 and is communicated with the washing pipe 4, a suction pipe 5 extending to the bottom of the bottle body 2 is arranged at the tail end of the washing pipe 4, the upper side caliber width of the suction pipe 5 is smaller than the lower side caliber width, and a notch 7 is arranged at the lower side of the suction pipe 5. In order to achieve the purpose of small residual quantity, the suction pipe extends to the bottom of the bottle body through the suction pipe which is arranged at the tail end of the flushing pipe and is small at the top and large at the bottom, the horn-shaped design is utilized, even if the liquid level in the bottle drops to be close to the bottom of the bottle, the suction pipe can be kept to have a large contact area with liquid, and finally the suction pipe is attached to the bottom and is used for the liquid in the bottle to flow through the notch, so after the bottle body is pinched by hand, the liquid is pressed from the notch to the flushing pipe by air pressure and is sprayed out through the nozzle, the suction pipe attached to the bottom can effectively discharge water when a small amount of water is in the bottle, the residual quantity of the washing bottle is small, and the working efficiency is increased.
