Description

  The present invention is used to remove clogs such as moss and dirt clogged in drainage outlets and drainage pipes such as sinks, flush toilets, washstands, and bathrooms. In addition, the present invention relates to a manual cleaning pump in which clogging is removed by applying a pressurizing action to eliminate clogging of a drain port and a drain pipe.

  In general, in places where water is drained, such as sinks, flush toilets, washstands, and bathrooms, moss, filth, hair, etc. may flow into the drainage outlet along with water. May become clogged.

Conventionally, in order to remove clogs such as pots clogged in the drain port and drain pipe, a cleaning tool (not shown) with a rubber bowl-shaped suction cup attached to the tip of a rod-shaped operation rod has been used. I came.
This cleaning tool presses the suction cups around the drainage outlets to bring them into close contact with each other, and holds the operation rod to reciprocate the suction cups in the vertical direction to alternately generate positive and negative pressure in the drainage outlets. The clogged material is forcibly moved to flow downstream to eliminate clogging of the drain outlet and drain pipe.

  However, since the volume in the bowl-shaped suction cup is small, the suction force and pressure applied to the clogged drain port and drain pipe are weak and the clogging of the drain port and drain pipe cannot be completely eliminated. There was a thing.

Therefore, in order to solve this problem, a manual pump type cleaning tool composed of a cylinder, a piston and the like has been developed in place of the suction cup type cleaning tool described above, and Japanese Utility Model Publication No. 64-14271 (Patent Document 1) and This is disclosed as Kaihei 4-65863 (Patent Document 2).
That is, although not shown, the two cleaning tools are reciprocated in the cylinder, a cylinder having a cap fitted to the upper end, a bowl-shaped suction cup attached to the lower end of the cylinder and closely attached to the periphery of the drain port. It consists of a piston inserted movably, a piston rod whose tip is connected to the piston, and a base end protruding from the cap, and a handle attached to the base end of the piston rod, and performs a suction action when the piston is lifted In addition, it is configured to perform a pressurizing action when the piston is pushed down.

  Thus, when removing the clogged matter in the drain port or drain pipe using both the cleaning tools, after the suction cup is brought into close contact with the periphery of the drain port, the handle is pulled up to move the piston upward. Then, the space below the piston in the cylinder is depressurized, and the clogged material is sucked up together with the water, and when the piston is moved downward by pushing down the handle, pressurized water is pressed into the drain pipe and drained. Water and clogs in the pipe are pushed out downstream. In this way, both the cleaning tools can increase or decrease the pressure by repeatedly moving the piston up and down (reciprocating), and can remove the clogging clogged in the drain port and the drain pipe.

However, since both of the cleaning tools have the cylinder formed in a straight line, there is a faucet near the drainage outlet like a sink or a washstand, or like a urinal in a men's toilet. If there is an edge, the edge of the faucet or urinal may become an obstacle when the handle is operated, and there is a problem that the cleaning tool cannot be used smoothly and smoothly.
In addition, since both the cleaning tools seal between the piston and the cylinder with a normal packing, when the packing is worn out, the sealing function is lowered and the suction action and the pressure action can be performed. There was a problem of disappearing.

Is inclined at an angle of The bottom end side of the cylinder 2 is inclined so that the handle 8 and the cylinder 2 etc. are flush with the sink A and the urinal edge of the men's toilet when the clogging of the drain outlet and drain pipe of the sink A and the like is eliminated. This is to prevent interference with the above.
The inclination angle on the lower end side of the cylinder 2 is set such that the handle 8 and the cylinder 2 do not interfere with the faucet or the like.

The cap 3 is formed of a plastic material or a metal material having excellent corrosion resistance, and is fitted to the upper end portion of the cylinder 2 and fixed to the upper end portion of the cylinder 2 by a plurality of cap mounting screws 14. A U-shaped handle 9 is attached to the cap 3 with a plurality of mounting screws 10 in an inclined posture.
In this embodiment, the hand-held handle 9 is attached to the cap 3 with the mounting screw 10, but in other embodiments, the hand-held handle 9 is attached to the cap 3 although not shown. May be formed integrally.

Further, the cylindrical body 4 is formed of an elastic rubber material and is detachably fitted to the lower end portion of the cylinder 2. The cylindrical body 4 is in close contact with the periphery of a drain outlet of the sink A, the flush toilet B or the like, and prevents leakage of pressure at the time of suction action and pressurization action.
In this embodiment, as shown in FIG. 2, the cylindrical body 4 is formed of a long cylindrical cylindrical body 4 made of an elastic rubber material and an elastic rubber material. A short cylindrical tube 4, a rectangular tube 4 formed of an elastic rubber material, a truncated cone-shaped large-diameter tube 4 formed of an elastic rubber material, and elasticity Each having a truncated cone-shaped small-diameter cylinder 4 formed of a rubber material, and each cylinder 4 has a size and shape of various drain outlets such as a sink A and a flush toilet B, and a position of the drain outlet. It is used properly according to etc.
For example, when the position of the drain outlet is at a deep position, the long cylindrical cylinder 4 is like a toilet when the position of the drain outlet is at a shallow position. When the outlet is large, a rectangular cylinder 4 is used. When the outlet is a bath outlet, a truncated cone cylinder 4 (large diameter or small diameter cylinder 4) is used. ing.
The long cylindrical cylinder 4 and the short cylindrical cylinder 4 are detachably attached directly to the lower end portion of the cylinder 2, and are a rectangular cylinder 4, a truncated cone-shaped large-diameter cylinder. 4 and a truncated cone-shaped small-diameter cylinder 4 are detachably attached to the lower end of the cylinder 2 via an adapter 15 shown in FIG. The adapter 15 includes a cap portion 15a that is detachably fitted to the lower end portion of the cylinder 2, a quadrangular cylindrical body 4, a truncated cone-shaped large-diameter cylindrical body 4, and the cap section 15a. It consists of a cylindrical portion 15b that is removably inserted into a small hole 4a formed in a truncated cone-shaped small-diameter cylindrical body 4.

  The piston 5 is formed in a thick disk shape from a plastic material or a metal material excellent in corrosion resistance, and is slidably inserted into the cylinder 2 through a pair of piston packings 6 described later. Has been. An annular packing groove 5 a for fitting the piston packing 6 is formed on the outer peripheral surface of the piston 5 at a predetermined interval.

The piston packings 6 are formed in a ring shape from a rubber material such as nitrile rubber, urethane rubber, or fluororubber, and have an outer peripheral edge portion 6a having an acute-angled cross section that is in contact with the inner peripheral surface of the cylinder 2 in a bent state. Each has it.
That is, as shown in FIG. 3, one piston packing 6 (lower piston packing 6) includes an outer peripheral edge portion 6a having a sharp cross-sectional shape in which the lower surface side of the outer peripheral edge portion 6a is formed on the tapered surface 6b. The outer peripheral edge 6a is in elastic contact with the inner peripheral surface of the cylinder 2 in a bent state (bent upward). Therefore, even when fluid enters between the inner peripheral surface of the cylinder 2 and the outer peripheral surface of the piston 5 and between both piston packings 6 when the piston 5 is pulled up, the outer peripheral edge portion of the lower piston packing 6 is kept in fluid pressure. As a result, the fluid is expanded and brought into close contact with the inner peripheral surface of the cylinder 2, and fluid leakage can be reliably prevented.
Further, as shown in FIG. 3, the other piston packing 6 (upper piston packing 6) is provided with an outer peripheral edge portion 6a having a sharp cross-sectional shape in which the upper surface side of the outer peripheral edge portion 6a is formed as a tapered surface 6b. The outer peripheral edge 6a is in elastic contact with the inner peripheral surface of the cylinder 2 in a bent state (a state bent downward). Therefore, even if fluid enters between the inner peripheral surface of the cylinder 2 and the outer peripheral surface of the piston 5 and between both piston packings 6 when the piston 5 is pushed down, the outer peripheral edge portion 6a of the upper piston packing 6 is not fluid pressure. As a result, the fluid is expanded and brought into close contact with the inner peripheral surface of the cylinder 2, so that fluid leakage can be reliably prevented.

The piston rod 7 is inserted into the cap 3 in a loosely fitted state and is inserted into the axial position of the cylinder 2, and its tip is connected and fixed to the piston 5 via a mounting nut 11 and a U nut 12.
The piston rod 7 is provided with a pair of buffering coil springs 13.
Further, a gap is formed between the piston rod 7 and the cap 3 to allow the air in the cylinder 2 in the space above the piston 5 to escape to the outside when the piston 5 is raised.

Next, an example in the case of removing clogs, such as moss clogged in drain outlets and drain pipes, such as sink A and flush toilet B, using manual cleaning pump 1 mentioned above is explained.
First, water is poured into a clogged drainage port such as a sink A or a flush toilet B, and a cylinder 4 that matches the size and shape of the drainage port is attached to the lower end of the cylinder 2 of the manual cleaning pump 1. At this time, when water has accumulated in the drain outlet in advance, it is not necessary to add water to the drain outlet.
Next, the tip of the cylinder 4 is immersed in water, the handle 8 is pulled up, water is sucked into the cylinder 2, and the space below the piston 5 of the cylinder 2 is filled with water.
Thereafter, with the cylinder 2 filled with water, the tip of the cylindrical body 4 is brought into close contact with the periphery of the drain outlet, and the handle 8 is pushed down strongly. If it does so, pressurized water will be inject | poured in a drain pipe from a drain outlet, and the clogging thing clogged up in a drain outlet or a drain pipe will be washed away downstream with water.
In addition, when the clogging of the drain port or the drain pipe is not eliminated by one extrusion operation, the cylinder 4 is separated from the periphery of the drain port, and the above process is repeated.

In the above description, the clogging of the drain outlet and the drain pipe is eliminated by the extrusion operation. However, if the clogging is generated near the drain outlet, the clogging of the drain outlet is eliminated by the suction operation. May be.
That is, the handle 8 is pushed down to move the piston 5 below the cylinder 2, and in this state, the cylinder 4 is brought into close contact with the periphery of the drainage port, and then the handle 8 is pulled up to move the piston 5 to above the cylinder 2. Move. If it does so, the space under the piston 5 in the cylinder 2 will be in a pressure-reduced state, and the clogging thing in a drain outlet will be sucked up and removed with water.
In addition, when the clogging of the drain port is not eliminated by one suction operation, the cylinder 4 is separated from the periphery of the drain port, and the above process is repeated.

  In addition, for clogged material that is tightly clogged in the drain port or drain pipe, the suction action and pressurizing action are repeated alternately, causing the clogged material to shake up and down, and sucking or pushing out the clogged material. You may make it remove.

As described above, the manual cleaning pump 1 can perform a suction action and a pressurization action on the clogged substances in the drain outlets and drain pipes of the sink A, the flush toilet B, etc., and therefore can cope with various clogs. The clogging of the drain outlet and the drain pipe can be reliably and satisfactorily eliminated.
The manual cleaning pump 1 has a lower end portion of the cylinder 2 inclined with respect to the axes of the piston 5 and the piston rod 7, so that there is a faucet such as a sink A or a wash basin. Even when there is an edge like a toilet urinal, the edge of the faucet or the toilet is not obstructed, and the manual cleaning pump 1 can be used well and smoothly.
Further, the manual cleaning pump 1 has a pair of piston packings 6 fitted on the outer peripheral surface of the piston 5, and the outer peripheral edge portions 6 a of both piston packings 6 are formed in acute cross-sectional shapes so that the inner periphery of the cylinder 2 is formed. Since it is in contact with the surface in a bent state, the sealing performance can be improved and a strong suction force and pressure can be exerted, and clogging of the drain port and drain pipe can be reliably and satisfactorily eliminated. .
