Description

Novel washing bottle capable of quickly balancing air pressure

Technical Field

The invention relates to laboratory equipment, in particular to a novel bottle washing device capable of quickly balancing air pressure, which is common equipment for washing glassware and plastic ware with deionized water in a laboratory, adding deionized water to a required volume when preparing a solution and the like.

Background

At present, in colleges and universities and scientific research institutions, bottle washing is a very widely applied equipment in laboratories. The traditional plastic washing bottle (structure shown in figure 1) is composed of a bottle body, a water outlet pipe and a bottle cap. Adding a proper amount of deionized water into a plastic washing bottle, and after a bottle cover is tightly covered, the air pressure in the bottle is the atmospheric pressure. When the plastic bottle body is extruded, the air pressure in the bottle rises and exceeds the atmospheric pressure, and water flows out of the water outlet pipe. When the bottle is released, the volume of the cavity in the bottle increases and the air pressure in the bottle drops to be lower than the atmospheric pressure and is negative pressure along with the outflow of water. At this time, the atmospheric pressure outside is greater than the atmospheric pressure in the bottle, and the outside air enters the upper part of the bottle through the liquid layer in the bottle from the water outlet pipe, and appears as bubbles entering the bottle, thereby balancing the pressure. It takes some time to equalize the negative pressure and the air pressure in the bottle is partially equalized but still at a negative pressure. When the bottle is completely loosened, the air pressure in the bottle is still negative pressure, then the bottle is extruded again, the labor is wasted, and the water outlet pipe has little water and is slow. So that the time is wasted when the traditional bottle washing is loosened to balance the air pressure, the labor is wasted when the bottle is squeezed, and the water outlet is slow and slow.

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

As shown in fig. 2 and 3, an embodiment of the present invention provides a novel wash bottle capable of rapidly balancing air pressure, including a bottle body 1, a water outlet pipe 2 and a bottle cap 3, wherein the water outlet pipe 2 is disposed at a side of the bottle body 1, and a lower end of the water outlet pipe 2 is communicated with a lower portion of the bottle body 1.

And a valve 4 for balancing the air pressure in the bottle body 1 is arranged on the washing bottle.

In this embodiment, the valve 4 is arranged in the bottle cap 3, the valve 4 comprises a lower cover 40, a cylinder 41 and a sphere 42, the upper end of the cylinder 41 is fixedly connected with the lower end face of the upper wall of the bottle cap 3, the bottle cap 3 is provided with an upper round hole 30, the lower cover 40 is provided with a lower round hole 400, the sphere 42 is arranged in the cylinder 41, and the diameter of the cylinder 41 is 1.1-1.3 times of the diameter of the sphere 42. The diameters of the upper round hole 30 and the lower round hole 400 are smaller than the sphere diameter of the sphere 42, and the sphere 42 floats in the cylinder 41 and between the upper round hole 30 and the lower round hole 400.

The valve 4 further comprises an emulsion ring 43, and the emulsion ring 43 is coated on the edge of the upper round hole 30 to ensure that the upper round hole can be completely sealed when the sphere moves upwards to the emulsion ring; when the sphere falls off the upper round hole, the external atmosphere is communicated with the gas in the valve.

The valve 4 further comprises 4 vertical rubber protrusions 44, and the 4 rubber protrusions 44 are uniformly distributed at the edge of the lower circular hole 400 along the circumferential direction. When the sphere falls down and is supported by the four rubber bulges or the sphere rises to leave the lower cover, the gas in the valve is communicated with the gas in the bottle body below through the lower round hole, namely the gas in the valve is always communicated with the gas in the bottle body.

The working principle of the invention is as follows: a proper amount of deionized water is added into the bottle body, and when a bottle cap with a valve is tightly covered, the air pressure in the bottle body is the atmospheric pressure. When the bottle body of the washing bottle is squeezed, the air flow in the bottle body enables the sphere to rise through the lower round hole of the valve. When the sphere rises to seal the upper round hole, the air pressure in the bottle body exceeds the atmospheric pressure due to the extrusion of the bottle body, and meanwhile, the water is discharged from the water outlet pipe. When the bottle body is loosened, the air pressure in the bottle body is reduced to be lower than the atmospheric pressure, and the sphere falls off the upper round hole under the action of gravity of the sphere, so that the outside air enters the bottle body through the upper round hole, and the negative pressure in the bottle body is balanced quickly. Therefore, the novel bottle washing machine overcomes the problems of long time and negative pressure for balancing air pressure when the traditional bottle washing machine is loosened. When the bottle body is squeezed again, the ball body in the valve rises to seal the upper round hole, the air pressure in the bottle body is increased, and meanwhile, the water is discharged from the water outlet pipe. The novel washing bottle can quickly balance the negative pressure in the bottle body when being loosened, so that the operation of loosening and squeezing the washing bottle is time-saving and labor-saving compared with the traditional washing bottle, and the water outlet pipe can quickly and greatly discharge water.

While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims.
