Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a liquid pumping pot, and more particularly to a lid structure for a liquid pumping pot.

The present invention includes a guide tube that vertically guides a press plate that presses and drives an air pump, and a guide tube that vertically guides a press plate that presses and drives an air pump is installed vertically on the top of the lid of a liquid pump pot, and the air pump is operated from the upper end of the guide tube. An engagement groove is provided below the position where the pressure plate is lowered by a distance greater than the stroke, and includes a vertical portion that allows vertical movement of the pressure plate and a horizontal portion that restricts the vertical movement of the pressure plate at an upper movement limit position. It is characterized by this.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A liquid pump pot according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

1 and 2 show a liquid pumping pot equipped with a manually operable bellows type air pump, which is an embodiment of the present invention.

In the figure, reference numeral 1 denotes the pot body, 2 a lid body pivotably attached to the upper part of the pot body 1 via a hinge pin 3, 4 an exterior case constituting the outer peripheral surface of the pot body 1, and 5 a pot body 1. 6 is a lower mouth member that constitutes the upper surface of the pot body 1, 7 is a liquid supply port formed in the center of the lower mouth member 6, and 8 is a lid body. 2 is a bellows-type air pump disposed within the interior; 9 is a press plate for driving the air pump 8; 10 is an inner stopper that is tightly fitted into the liquid supply port 7; 11 and 12 are provided within the inner stopper 10. The ventilation passage and liquid passage, 13 and 14 are liquid passage 1.
A liquid pumping pipe and a liquid pouring pipe communicate the inside and outside of the pot body 1 via 2, and 15 represents a lock lever, respectively.

Further, a guide tube 19 is integrally provided vertically on the lid body 2, into which the air pump 8 and a pressure plate 9 for driving the air pump are loosely fitted so as to be movable up and down.

A circumferential wall 9a having a slightly larger diameter than the outer diameter of the air pump 8 is integrally vertically provided on the outer periphery of the pressing plate 9, and the upper part of the air pump 8 is loosely fitted into the circumferential wall 9a.

A doughnut-shaped intermediate member 20 is interposed between the press plate 9 and the top plate 8a of the air pump 8.

Further, on the outer periphery of the front guide cylinder 19, a cage-shaped rotating member 21 is rotatably disposed.

A notch recess 22 is provided at an appropriate position on the upper end of the rotating member 21.
is formed, and an operating member 23 for rotating the rotating member 21 is force-fitted and fixed in the notch recess 23 .

The operating member 23 protrudes from an elongated hole 24 formed in the lid body 2 at a position above and near the lock lever 15.

On the outer periphery of the intermediate member 20, three L-shaped locking legs 25, 25, 25 are integrally hung at equal intervals.

The locking legs 25, 25, 25 are provided with guide grooves 26, 26, 2 cut out from the lower end side of the guide tube 19.
6 and moves up and down while being guided by the guide grooves 26, 2.
It engages with the upper ends of 6 and 26 and functions to restrict the upper limit of movement of the air pump 8.

Three engaging protrusions 27, 27, 27 are integrally provided at the lower end of the peripheral wall 9a of the pressing plate 9,
The engaging protrusions 27, 27, 27 are connected to the guide tube 19.
The guide grooves 26, 26, 26 are adapted to be engaged with inverted L-shaped engagement grooves 28, 28, 28, which are cut out from the lower end side at intermediate portions of the guide grooves 26, 26, 26. That is, when each engagement protrusion 27 is engaged with the vertical portion 28a of each engagement groove 28, the pressing plate 9 can be moved up and down, and each engagement protrusion 27 is engaged with the vertical portion 28a of each engagement groove 28.
When engaged with the horizontal portion 28b of the press plate 9, the press plate 9 is at the upper limit position and cannot move up and down.

Here, the distance l between the upper end of the guide tube 19 and the upper ends of the guide groove 26 and the engagement groove 28 is
This prevents the upper portions of the guide groove 26 and the engagement groove 28 from being exposed when the pressing plate 9 moves downward.

Further, on the peripheral wall 9a of the pressing plate 9, the engaging protrusion 2
7, 27, 27, there is a cutout hole 2 in which the locking legs 25, 25, 25 of the intermediate member 20 should face.
9, 29, 29 are formed.

Each notch hole 29 is formed to be large so that the intermediate member 20 does not rotate together when the pressing plate 9 is rotated in an arc.

Furthermore, a pressing plate 9 is provided on the peripheral wall of the rotating member 21.
The engagement hole 3 in which the engagement protrusions 27, 27, 27 engage
0, 30, 30 and the locking legs 25, 2 of the intermediate member 20
Engagement windows 31, 31, 31 with which 5 and 25 engage are formed alternately at equal intervals.

Each of the engagement holes 30 is formed narrowly so that each of the engagement protrusions 27 can move only in the vertical direction, while each of the engagement windows 31 allows each of the locking legs 25 to move in the vertical and circumferential directions. It is formed to be wide. That is, when the rotating member 21 is rotated, the intermediate member 20
does not rotate, and only the press plate 9 rotates together.

In this embodiment, the rotating member 21, the pressing plate 9
The engaging protrusions 27, 27, 27 and the engaging grooves 28, 28, 28 of the guide tube 19 constitute a safety mechanism. That is, as the rotating member 21 rotates in the direction of arrow A or B, the pressing plate 9 is rotated, and each engaging protrusion 27 is aligned with the vertical portion 28a or horizontal portion of each engaging groove 28 of the guide tube 19. By engaging with the portion 28b, the pressing plate 9 is made vertically movable or non-moveable, thereby making the air pump 8 drivable or non-drivable.

Next, the operation of the illustrated liquid pumping pot will be explained.

When using the pot, each engaging protrusion 27 of the pressing plate 9
are engaged with the horizontal portions 28b of each engagement groove 28, and the air pump 8 is rendered inoperable.

When using the pot, when the operating member 23 is rotated in an arc in the direction of arrow A, the rotating member 21 and the pressing plate 9
rotates in an arc in the direction of arrow A, and each engaging protrusion 27 engages with the vertical portion 28a of the engaging groove 28, so that the air pump 8 can be driven. Then, pressurized air is blown into the liquid container 5 from the air pump 8, and the liquid in the liquid container 5 is led out to the outside through the liquid pumping pipe 13 and the liquid pouring pipe 14.

When opening the lid 2, the operating member 23 is rotated in an arc in the direction of arrow A and the lock lever 15 is pressed with a finger.
The lock is released, and the lid body 2 can be opened.

Next, the effects of the liquid pump pot of the present invention will be described.

According to the present invention, a guide tube 19 for vertically guiding a press plate 9 for pressing and driving an air pump 8 is integrally provided vertically on the top of the lid body 2 of the liquid pumping pot, and the guide tube 19 is integrally disposed vertically from the upper end of the guide tube 19. The vertical portion 28a that allows the vertical movement of the pressing plate 9 is regulated at the upper limit position of the pressing plate 9 from a position lowered by a distance l that is larger than the operating stroke S of the air pump 8. Since the engaging groove 28 consisting of the horizontal portion 28b is provided, a portion of the engaging groove 28 is not exposed when the pressing plate 9 moves downward, resulting in a good appearance.
