Description

Toilet Pump {TOILET PUMP}

The present invention relates to a toilet pump used when a toilet is clogged, and more particularly to a piston type toilet pump.

The conventional toilet pump 10 comprises a pull rod 11 and a pump body 12 coupled to the lower end thereof as shown in Fig.

2, the pump body 12 is pressed on the handle bar 11 in a state in which the pump body 12 is covered on the drain port 2 on the side of the toilet 1 to compress the air in the pump body 12, 2 so that the foreign substances trapped in the drain port 2 flow out along the flow path.

However, according to the conventional toilet pump 10, there is a problem that the amount of air that can be accommodated in the pump body 12 is limited, so that it is insufficient to sufficiently compress the drain hole 2.

In addition, when compressed air is pressurized by such a force, the compressed air does not flow into the drain port (2). Instead, the water flows out through the rim of the pump body (12) There has been a problem that it is splashed to the outside of the apparatus (1).

When the handle bar 11 is repeatedly operated up and down, the semicircular pump main body 12 may be turned upside down due to a stroke greater than necessary. In addition, the inverted pump main body 12 may be resiliently deformed There was a problem that the soil was spattered during the restoration process.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a toilet pump capable of inflowing a sufficient amount of air to compress a toilet side drain hole and preventing a phenomenon that compressed air flows out to the outside and that a dirt is leaked.

In order to accomplish the above object, the present invention provides a toilet pump, comprising: a cylinder having an inner opening in an axial direction extending vertically; A cylinder head accommodated in the cylinder and slidable in a longitudinal direction of the cylinder; a cylinder head mounted at a lower end portion of the cylinder, the handle being formed at an upper end exposed through the upper end of the cylinder; A piston having a cylinder rod; And a flexible plug made of a material capable of being elastically deformed so as to be able to be inserted into the inner circumferential surface of the toilet-side drain hole in such a manner that a rim wall portion of a predetermined thickness, which is engaged with the lower end portion of the cylinder and communicates with the inside of the cylinder, The present invention also provides a toilet pump.

The piston has an outer circumferential surface of the cylinder head spaced apart from an inner circumferential surface of the cylinder and having a predetermined width in the axial direction along the outer circumferential surface of the cylinder head, An O-ring which is in close contact with a periphery of the cylinder head and is slidable up and down in the rim groove, and a vent hole formed in a lower end surface of the cylinder head to communicate with the rim groove, have.

The toilet pump includes a flange that is inserted into a lower end portion of the cylinder and extends in a radial direction, a washer that presses the upper end of the flexible plug so as to be in close contact with the flange, And a bolt that is coupled to the lower end of the flexible plug and communicates with the inside of the cylinder through a through hole formed in the axial direction.

At this time, the flexible plug may be made of a rubber material.

As described above, according to the toilet pump according to the present invention, the compressed air is pushed in using the piston in a state in which the flexible plug of elastic material is closely inserted into the inner peripheral surface of the toilet side drain hole, It is possible to prevent the phenomenon that the compressed air flows out to the outside and the outflow of the dirt.

Fig. 5 is a bottom view of the flexible plug, which is a component of the toilet pump of Fig. 3,
FIG. 6 is a schematic view showing the state of use of the toilet pump of FIG. 3;

3, the toilet pump 100 according to an embodiment of the present invention includes a cylinder 110 which extends in the vertical direction and has an opening therein, a cylinder 110 inserted into the cylinder 110, And a rod 121. A handle 122 is integrally formed at the upper end of the cylinder rod 121 exposed through the upper end of the cylinder 110.

A cylindrical flexible plug 130 having a bottom opened is coupled to the lower end of the cylinder 110.

4, a cylinder head 123 is mounted on a lower end portion of a cylinder rod 121 inserted into the cylinder 110. As shown in Fig.

The outer circumferential surface of the cylinder head 123 is spaced apart from the inner circumferential surface of the cylinder 110, and a circumferential groove portion 123a is formed along the circumferential surface. The edge groove portion 123a is formed to have a predetermined width w in the vertical axis direction.

An O-ring 124 is fitted in the edge groove portion 123a. The O-ring 124 has a diameter which is in close contact with the inner circumferential surface of the cylinder 110. Accordingly, the O-ring 124 is slid downward (in the case of b) or upward (in the case of a) in the edge groove portion 123a in accordance with the upward and downward sliding of the cylinder head 123.

The lower end face 123b of the cylinder head 123 has a vent hole 123c and communicates with the edge groove 123a.

According to the structure of the cylinder head 123 and the O-ring 124, when the user slides the cylinder rod 121 down to slide it as shown in FIG. 4A, the O- And is positioned at the upper end of the cylinder head 123a and is in close contact with the inner wall of the cylinder 110 to pressurize the air located below the cylinder head 123 in a state of being blocked from the upper portion.

4 (b), when the user pulls the cylinder rod 121 upward, the O-ring 124 is positioned at the lower end of the rim groove 123a, The lower portion of the cylinder head 123 is maintained in a state in which the lower portion of the cylinder head 123 communicates with the upper portion of the cylinder head 123 through the vent groove 123a through the vent hole 123c, And then flows into the lower portion of the cylinder head 123.

Therefore, even if the user pulls the cylinder rod 121 upward, no wastewater flows through the lower end of the cylinder 110.

At this time, the upper air of the cylinder head 123 flows from the outside through the through hole 111 formed in the upper end of the cylinder 110, as shown in FIG.

The cylindrical flexible plug 130 passes through the closed top end of the flexible plug 130 through the lower end of the cylinder 110.

Specifically, the flange 112 is fitted in the lower end of the cylinder 110, and the upper end of the flexible plug 130 is closely attached to the bottom surface of the flange 112 extending in the radial direction.

5 (a), when the washer 113 is inserted into the flexible plug 130 and the bolt 114 is inserted into the flexible plug 130 in a state in which the washer 113 is in close contact with the upper end, Threaded.

Accordingly, the bolt 114 closely supports the washer 113 in the upward direction, and thus the upper end of the flexible plug 130 is fixed to the lower end of the cylinder 110.

A through hole 114a is formed through the bolt 114 at the center in the axial direction.

The inside of the cylinder 110 is vertically communicated with the inside of the flexible plug 130 through the through hole 114a.

On the other hand, the flexible plug 130 is made of a material which can be elastically deformed easily. In this embodiment, the flexible plug 130 is made of a rubber material.

5 (a), when the user presses the edge wall portion 131 of the flexible plug 130, the edge wall portion 131 is easily deformed as shown in FIG. 5 (b).

6, the flexible plug 130 of the elastic material, which is easily deformed by the external force and easily restored to its original shape by the removal of the external force, When the flexible plug 130 is pushed in, the edge wall portion 131 is inserted downward in a state of being tightly contacted with the inner circumferential surface of the drain hole 2 while being broken.

Therefore, even when the user operates the piston 120 up and down, the compressed air flowing into the flexible plug 130 flows into the drain pipe 3 as it is, 1). &Lt; / RTI >

Meanwhile, since the toilet pump 100 described above is only one embodiment for facilitating the understanding of the present invention, it is difficult to understand that the scope of the present invention and the technical scope thereof are limited to those described above.

The scope of rights and technical scope of the present invention are determined by the scope of claims for utility model registration described below and the equivalents thereof.
