Abstract
A reversing valve comprises a reversing valve body, a liquid suction pipe and a steel ball, wherein the reversing valve body comprises a valve cavity, an insertion pipe communicated with the valve cavity, a connector and a one-way valve cavity with an opening at the upper end, the valve cavity is communicated with the connector, a steel ball seat is arranged in the one-way valve cavity, and the axes of the insertion pipe, the valve cavity and the connector are on the same straight line; the pipette is inserted into the interface, the steel ball is matched with the steel ball seat, and the steel ball is kept in the one-way valve cavity. An atomizing pump comprises a body and a reversing valve, wherein a plug pipe of the reversing valve is plugged with a liquid suction interface at the lower end of the body. When the valve is upright, liquid flows in the direction of the liquid suction pipe, the valve cavity and the insertion pipe; when the valve is turned upside down, liquid enters the insertion pipe through the one-way valve body and the valve cavity; the reversing function is realized. A spray pump can spray when standing upright or standing upside down, and is convenient for use.
Description
Technical Field
The utility model relates to a spray pump, especially a switching-over device for spray pump.
Background
At present, in the prior art, a spray pump comprises a press head, a screw thread, a lock cover, a body, a main column, an auxiliary column, a piston, a glass ball, a main spring andor an auxiliary spring and a suction pipe, wherein a suction pipe interface is arranged at the lower end of the body, and the suction pipe is spliced with the suction pipe interface. There are problems in that: when in normal use, the press head is positioned above the container, the press head is pressed, and the liquid in the container enters the suction pipe and then is sprayed out by the press head; when the liquid container is inverted, the joint is positioned below, the liquid inlet pipe of the suction pipe is positioned at the top, and no liquid enters the suction pipe.
SUMMERY OF THE UTILITY MODEL
The utility model aims at: a reversing valve is provided which is characterized in that the spray pump can be used both upright and inverted.
The utility model discloses another purpose is: provides a spray pump which has the characteristics of upright and inverted uniform spraying.
The utility model discloses a realize like this: a reversing valve, which comprises a reversing valve body, a liquid suction pipe and a steel ball,
the reversing valve body comprises a valve cavity, an insertion pipe communicated with the valve cavity, a connector and a one-way valve cavity with an opening at the upper end, the one-way valve cavity is communicated with the valve cavity, a steel ball seat is arranged in the one-way valve cavity, and the axes of the insertion pipe, the valve cavity and the connector are on the same straight line;
the pipette is inserted into the interface, the steel ball is matched with the steel ball seat, and the steel ball is kept in the one-way valve cavity.
The reversing valve is characterized in that: the one-way valve cavity is provided with an axial liquid inlet hole.
The reversing valve is characterized in that: the upper end of the inner wall of the one-way valve cavity is provided with at least two bulges.
The reversing valve is characterized in that: the protrusion is a spherical curved surface.
An atomizing pump comprises a body, wherein a plug pipe of a reversing valve is plugged with a liquid suction interface at the lower end of the body.
When the reversing valve is upright, liquid flows in the direction of the liquid suction pipe, the valve cavity and the insertion pipe; when the valve is turned upside down, liquid enters the insertion pipe through the one-way valve body and the valve cavity; the reversing function is realized. A spray pump can spray when standing upright or standing upside down, and is convenient for use.

Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1 and fig. 2, the reversing valve comprises a reversing valve body 1, a liquid suction pipe 2 and a steel ball 3,
the reversing valve body 1 comprises a valve cavity 11, an insertion pipe 12 communicated with the valve cavity, a connector 13 and a one-way valve cavity 14 communicated with the valve cavity and provided with an opening at the upper end, a steel ball seat 141 is arranged in the one-way valve cavity 14, and the axes of the insertion pipe 12, the valve cavity 11 and the connector 13 are on the same straight line;
the pipette 2 is inserted into the interface 13, the steel ball 3 is matched with the steel ball seat 141, and the steel ball 3 is kept in the one-way valve cavity 14.
The one-way valve cavity 14 is provided with an axial liquid inlet hole 142.
The upper end of the inner wall of the one-way valve cavity 14 is provided with two bulges 143, and the two bulges 143 are arranged on a same diameter line;
the protrusion 143 has a spherically curved surface.
As shown in figure 1, the spray pump 4 comprises a body 5 and a reversing valve, wherein a connecting pipe 12 of the reversing valve is connected with a liquid suction interface 51 at the lower end of the body 5 in a connecting mode.
After the spray pump 4 in the prior art is provided with the reversing valve, when the container is upright, the liquid suction pipe 2 extends into the bottom of the container, the liquid inlet end of the liquid suction pipe 2 is opposite to the ground, and the steel ball 3 of the reversing valve is tightly matched with the steel ball seat 141; pressing the pressing head 41 of the spray pump 4, enabling the liquid in the container to enter the body 5 of the spray pump 4 through the pipette 2, the valve cavity 11 of the reversing valve and the inserting pipe 12, and finally spraying out from the pressing head 41;
when the container is inverted, the liquid inlet end of the liquid suction pipe 2 extends into the liquid outlet surface, the steel ball 3 of the reversing valve leaves the steel ball seat 141, the steel ball is matched with the bulge 143 to stop the position, and the liquid enters the one-way valve cavity 14 through the liquid inlet hole 142 of the one-way valve cavity 14 and then enters the valve cavity through the steel ball seat 141, so that inverted spraying is realized.
What has been described above is only a preferred embodiment of the present invention. It should be noted that, for a person skilled in the art, several modifications and variations can be made without departing from the principle of the invention, which is also considered as the protection scope of the invention.
