Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a detergent container pumping device,

The present invention relates to a coupling structure of a detergent container pumping device and a pressurized metal head, and more particularly, to a detergent container pumping device and a pressing metal head, Heads.

A detergent container and a pumping device are provided below the sink top plate, and a detergent supply device for exposing only a nozzle and a pressure head for discharging the detergent from the detergent container is provided above the sink top plate.

Korean Registered Utility Model No. 20-0380593 discloses a push button (pressurizing head) made of zinc which is coupled to a detergent container and injects detergent into the nozzle by the pressure of the pumping member. The lower end of the push button is pumped A sealing guide tube made of a synthetic resin material having a sealing hole for sealing the upper end of the member and having a sealing insertion hole to which the tip of the nozzle is inserted and sealed so as to be hermetically sealed is fixed to one side of the upper portion, .

Korean Unexamined Utility Model Application Publication No. 20-2009-0001394 discloses a washing machine comprising a detergent container, a support for receiving the detergent container through the upper plate of the sink, a connection port for attaching the detergent container to the upper end of the detergent container, A pumping unit which is mounted on a support and which is connected to a cylinder connected to a suction hose at a lower end thereof through a suction hose and a piston pipe which pressurizes the inside of the cylinder, a nozzle cap (pressure head) coupled to the piston pipe of the pumping unit, And a packing holder which is mounted in the nozzle cap and which is in close contact with the outer peripheral surface of the piston pipe and which is made of a soft material having a high friction coefficient to firmly hold the piston pipe in the fitting state. A detergent dispenser is disclosed. According to Korean Utility Model Application Publication No. 20-2009-0001394, since the state of the nozzle cap and the piston pipe are made more rigid by the packing holder than the conventional case, the nozzle cap and the piston pipe are separated from each other, So that the nozzle cap and the piston pipe can be easily separated from each other by a simple fitting method. As a result, it is possible to easily separate the nozzle cap and the piston pipe, And the inside of the piston pipe can be easily cleaned.

Korean Utility Model Registration No. 20-0306330 discloses a structure in which a pressing member (pressurizing head) for supplying a detergent solution and a fastener body for fixing the solution dispenser are coupled with a fastening ring at the bottom of the sink to replenish the dispenser without disassembling the dispenser. FIG. 1 of Korean Registered Utility Model No. 20-0306330 shows a structure in which a pressing member and a fixing pipe are combined.

In Korean Utility Model No. 20-2009-0001394 and Korean Utility Model No. 20-0306330, although the pressure head (nozzle cap, pressing member) is molded by plastic injection molding, it is very light, but Korean Utility Model No. 20-0380593 The pressure head (pushbutton) is molded of zinc and is relatively heavy. When the pressure head is formed into zinc as in Korean Registered Utility Model No. 20-0306330, the detergent can be easily discharged because the detergent is pumped even if the user applies a small pressure.

However, when the push button (pressurizing head) is formed into zinc as in Korean Utility Model Application No. 20-0306330, there is a concern about corrosion of the push butt (pressurizing head) by the detergent. When a discharge pipe of a pumping device is connected to a sealed induction pipe such as a Korean Registered Utility Model No. 20-0306330, the detergent remaining in the push button leaks through a gap between the discharge pipe of the pumping device and the sealed induction pipe, . In addition, when a push button (pressurizing head) such as the Korean Registered Utility Model No. 20-0306330 is used, the gap between the sealed induction pipe and the discharge pipe of the pumping device is not fixed and sliding friction is repeatedly generated. , The leakage amount of the detergent increases with time, and when the degree of wear is severe, the push button may be detached from the discharge pipe of the pumping device during use.

When the nozzle cap (pressurizing head) is manufactured from a small plastic molding as in Korean Utility Model Application Publication No. 20-2009-0001394, the pumping action of the detergent is not smooth. This is because the user must press the nozzle cap in the correct direction using a large force to perform detergent pumping. In addition, even if a packing holder is further inserted between the piston pipe and the nozzle cap as shown in Korean Utility Model Application Publication No. 20-2009-0001394, the piston pipe reciprocates in the vertical direction during each pumping operation, so that the packing holder wears easily , The detergent remaining in the nozzle cap tends to leak.

FIG. 1 of Korean Registered Utility Model No. 20-0306330 shows a protrusion formed on an upper portion of a fixing pipe inserted in a pressing member. However, since the internal space of the pressing member into which the fixing pipe is inserted is formed flat, the projection formed around the fixed pipe made of plastic can be pumped several times while the fixing pipe is inserted into the pressing member, Even if only the action is crushed, the detergent is leaked.

The present invention has been made to solve the problems occurring in the coupling structure of the detergent container pumping device and the pressure head described above, and an object of the present invention is to provide a detergent container pumping device and a pressure head, So as to provide a detachable container pumping device and a pressurizing metal head coupling structure which are free from detachment.

According to another aspect of the present invention, there is provided a pumping device coupled to a kitchen detergent container, wherein an annular protrusion is formed on an outer circumferential surface of a discharge pipe of the pumping device, and an inner circumferential surface of the hollow portion of the pressurized metal head, And the annular protrusion of the outer circumferential surface of the discharge pipe is seated in the annular groove of the inner circumferential surface of the pressurizing metal head when assembled.

A plurality of annular grooves formed on an inner peripheral surface of the pressurized metal head are formed at equal intervals from an upper point spaced apart by a distance from a lower end of the pressurizing metal head; Wherein the annular protrusion is formed at the same interval as the number of the annular recesses and a stepped portion is formed at a lower portion of the annular protrusion formed at the lowermost end among the annular protrusions, And the annular protrusion is seated in the annular groove by simply inserting it into the hollow portion of the pressing metal head and press-fitting the annular protrusion.

According to the present invention, even if the annular protrusion is seated in the annular groove and the detergent pumping action is repeated, no flow occurs between the pressurized metal head and the discharge pipe of the pumping device. Accordingly, even when the annular protrusion is not worn and the pumping action is repeated for a long period of time, there is no gap between the discharge pipe and the pressurizing metal head of the pumping device, thereby preventing leakage of the detergent. As shown in Fig. Particularly, by adjusting the distance between the stepped jaws and the annular protrusion and the annular groove, the annular protrusion can be seated in the annular groove very quickly and tightly when assembled. When the seat is once seated, the discharge pipe and the pressurized metal head of the pumping device maintain a large sealing force There is an effect that it is firmly fixed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, a concrete embodiment of a coupling structure of a detergent container pumping device and a pressurized metal head according to the present invention will be described in detail with reference to the accompanying drawings.

1, the present invention relates to a coupling structure of a pumping device 13 coupled to a kitchen detergent container and a pressurized metal head 3 for operating the pumping device 13. As shown in Fig. In the present invention, the pressurized metal head 1 is formed of brass having a specific gravity of about 8.73 or more, or bronze having a specific gravity of about 8.735, and its surface is chrome plated. Since brass or bronze having such a specific gravity is heavier than zinc (specific gravity: 7.133), not only is it possible to smoothly perform the pumping action with a small pressing force, but also the synthetic induction tube There is no need to insert. However, when the pressurized metal head 3 is made of a heavy material such as a brass or bronze material, the pressure metal head 3 and the pumping device 13, Detergent leakage frequently occurs on the connection portion between the pumping device 13 and the pressurizing metal head 3 when the pressurizing metal head 3 is repeatedly used for a long period of time.

1 and 2, when the pumping device 13 presses and releases the nozzle 11 integrally coupled to the pressurized metal head 3 or the pressurized metal head 3 once, the discharge pipe 15 is also pressed against the pressurized metal head 3 3, the pumping device 13 sucks and discharges the amount of the detergent through the suction pipe 21 at the lower end while compressing and restoring it in the pumping device 13. The detergent discharged through the discharge pipe 15 passes through the inner hollow portion 5 of the pressurized metal head 3 and is discharged to the outside by the nozzle 11 (see FIG. 3). Although not shown in the drawing, a suction hose is connected to the suction pipe 21 and extends to the lower end of the detergent container. The discharge pipe 15 is connected to the piston and the restoring spring in the pumping device 13, and when the discharge pipe is pushed downward once, a single amount of the detergent is discharged through the discharge pipe 15. The internal structure of the pumping device 13 is not a component of the present invention, and since the internal structure of a known pumping device is used as it is in the present invention, a detailed description of the internal structure of the pumping device is omitted in the description of the present invention.

2 and 3, a feature of the present invention is that the annular protrusion 17 is formed on the outer peripheral surface of the discharge pipe 15 of the pumping device 13 and the discharge pipe 15 of the pumping device 13 The annular recess 9 is formed in the inner circumferential surface of the hollow portion 5 of the pressurizing metal head 3 to be inserted into the annular protrusion 17. In this case, the discharge pipe of the pumping device 13 is formed of a soft material such as polyethylene (PE), and the projecting portion cross-sectional area of the annular projection 17 is larger than the sectional area of the annular groove 9, 17 are seated in the annular groove 9, it is preferable that the annular projection 17 is completely filled in the annular groove 9 in a slightly contracted state. In such a case, there is no leakage of the liquid remaining in the pressurized metal head 3, and even when detergent pumping is performed by pushing the nozzle 11, the pressurized metal head 3 and the discharge pipe 15 of the pumping device 13 No flow or sliding occurs and there is no abrasion of the annular projection.

A further feature of the present invention is that a plurality of annular grooves 9 formed on the inner circumferential surface of the pressurizing metal head 3 are formed at equal intervals from an upper point spaced a distance from the lower end of the pressurizing metal head 3 Like projections 17 formed on the outer circumferential surface of the discharge pipe 15 of the pumping device 13 are formed at the same interval as the number of the annular recesses 9. The annular protrusions 17 formed at the lowermost end of the annular protrusions 17, A stepped step 19 is formed at a lower position spaced apart by a distance a from the nozzle 17 so as to be caught by the lower end of the hollow portion of the pressurized metal head 3 so that the discharge pipe 15 of the pumping device 13 is connected to the pressurized metal head 3, And the annular protrusion is seated tightly in the annular groove by only being inserted into the hollow portion 5 of the annular groove 5 and press-fitting.

The outer diameter of the lower portion 15a of the stepped portion 19 of the discharge pipe 15 is preferably larger than the outer diameter of the upper portion 15b having the annular protrusion 17 formed therein.

The lower hollow portion 5a into which the outer diameter of the upper portion 15b of the discharge pipe 15 is inserted is larger than the outer diameter of the upper portion 15b of the discharge pipe 15, And the upper hollow portion 5b is formed with a stepped reduced inner diameter so that the annular projection 17 formed on the soft discharge pipe 15 during assembly is inserted into the annular groove 9 So that it is easily seated.

According to the present invention having such a configuration, even when the annular protrusion 17 is seated very tightly in the annular groove 9 so that the detergent pumping action is repeated, the pressure between the pressurized metal head 3 and the discharge pipe 15 of the pumping device No flow occurs. Therefore, even when the abrasion of the annular protrusion 17 which is soft does not occur and the pumping action is repeated for a long period of time, no gap is formed between the discharge pipe 15 of the pumping device 13 and the pressurizing metal head 3, And the pressurized metal head 3 is not released from the pumping device 13 in the detergent pumping process. Particularly, by adjusting the distance between the stepped step 19 of the discharge pipe 15 and the annular protrusion 17 and the annular recess 9 of the pressing metal head 3, the annular protrusion 17 can be quickly and tightly assembled to the annular recess The discharge pipe 15 of the pumping device 13 and the pressurizing metal head 3 are firmly fixed while maintaining a large sealing force.
