2. Description of the Related Art A trigger type upside-down pump is provided with a suction path automatic switching device for switching between an upright path and an inverted path at a suction port of a pump body, and a suction pipe is connected to the upright path side. Then, the suction pipe is extended to the lower part in the container, and the inverted flow path is opened to the head in the container. Further, in order to prevent a negative pressure inside the container body due to the ejection of the liquid, an outside air introduction passage which is opened by pulling a trigger on the pump body is provided. This trigger-type upside-down dual-purpose pump is used by being attached to the mouth and neck of a container body containing a liquid, but at the time of erecting, the suction flow path automatic switching device opens only the erecting flow path.
By operating the trigger to operate the pump body, the liquid in the container is sucked up into the pump body through the suction pipe and ejected from the nozzle. When the head is inverted, the suction flow path automatic switching device opens only the inverted flow path, and therefore, the trigger body is operated by operating the trigger, so that the liquid entering the head in the container body with the head is inverted. The water is sucked into the pump body through the passage and is ejected from the nozzle. Then, each time the trigger is operated, the outside air introduction path is opened, the outside air flows into the container, and the negative pressure inside the container due to the ejection of the liquid is prevented.

However, in this type of trigger-type inverted dual-purpose pump, the outside air introduced at the time of inversion to prevent the negative pressure from being introduced into the liquid inside the head inside the container in the inverted posture. As a result, the liquid enters the inverted flow path, which is supposed to suck only the liquid, and deteriorates the ejection state from the nozzle. Therefore, the present invention prevents such intrusion of air into the pump main body when the pump is inverted, thereby preventing the state of ejection from the nozzle from deteriorating, and also simplifies the suction passage automatic switching device. Is what you do.

The trigger type upside down dual-purpose pump A is operated with the liquid stored in the container body B. First, in the case of the upright posture, the suction path automatic switching device 3 The passage control valve 12 is closed when the ball valve is seated on the tapered valve seat, so that the liquid in the container A passes through the suction pipe 4 and the erecting flow path 5 of the automatic suction flow path switching device 3. The water is sucked up by the pump body 1 and ejected from the nozzle 23 of the pump body. Also, when lying down with the nozzle 23 down,
By the suction pipe 4 inclined forward, most of the liquid remaining in the container A is sucked up without any trouble even if the amount of the liquid is low. Next, in the deep forward or inverted posture, the flow path control valve 12 in the automatic suction flow path switching device 3 opens when the ball valve is separated from the tapered valve seat, so that the head inside the container body A The liquid in the section flows into the erecting flow path 5 from the flow path opening 7 through the inverted flow path 6, is sucked into the pump body 1, and is ejected from the nozzle 23 of the pump body. In this inverted posture, as long as the flow path from the inverted flow path 6 to the erect flow path 5 is submerged in the liquid, the liquid in the inverted container body B naturally flows into this flow path. Air in body B is suction pipe 4
Does not flow into the erecting flow path 5 from the outlet. In the deep forward tilting position, the liquid in the head portion is easily sucked into the pump main body 1 even if the liquid in the container A is low because the channel opening 7 of the inverted flow channel 6 is located below. When the liquid in the container body A is sucked into the pump body 1 and ejected from the nozzle 23 in this way, the inside of the container body A becomes negative pressure, and the outside air flows into the container body A through the outside air introduction passage 10. Inhaled. However, this outside air introduction passage 10 is opened when the pump piston 22 is pushed in by the operation of the trigger 9 to introduce outside air, and supplies the outside air into the container A through the outside air introduction groove 16.

By the way, in the case of the deep forward or inverted posture, as described above, the inverted flow path 6 works, and the liquid in the head portion in the container A is passed through the inverted flow path 6 from the flow path port 7 through the inverted flow path 6. The liquid flows into the vertical flow path 5, is sucked into the pump main body 1, and is ejected from the nozzle 23 of the pump main body. Rises as air bubbles and passes near the flow path port 7, but at this time, the air exclusion cylinder 11 covering the flow path port 7 is prevented from entering the flow path port 7.

According to the first to fifth aspects of the present invention, an air exclusion cylinder 11 having an open lower end is attached to the outside of the automatic suction flow path switching device 3 so that the flow path port 7 can be passed through. Even when the inverted flow path 6 is operated in a deep forward or inverted posture, the outside air flowing from the outside air introduction path 10 into the liquid in the head portion of the container body A can be covered. Therefore, there is no adverse effect on the ejection of the liquid from the nozzle 23, and a good ejection can always be obtained.
