This application is based on and claims the benefits of priorities from Japanese Patent Application No. 2005-108306, filed on 5 Apr. 2005 and Japanese Patent Application No. 2006-007996, filed on 16 Jan. 2006, the contents of which are incorporated herein by reference.
1. Field of the Invention
The present invention relates to cleaning implements. More particularly, the present invention relates to cleaning implements adapted for coverings for floors or carpets, for example, and including a liquid supply device.
2. Related Art
By way of example, a cleaning implement including a liquid supply device is designed to have a cleaning head arranged at a distal end of a holding stem obtained by connecting pipes. A nozzle is provided at the cleaning head, and a water container is provided at the holding stem. A cleaning implement having a water ejection function, in which a handle is provided at a grip of a holding portion, and when operating the handle, a piston arranged in the water container is actuated to eject water in the water container from the nozzle, is provided. (Refer, for example, to Japanese Utility Model Registration No. 3094858, Patent Document 1).
According to Patent Document 1, in synchronization with operation of the handle, water in the water container flows toward the nozzle on the cleaning head so as to eject a proper amount of clean water on a floor at any time, allowing enhancement in effects of cleaning the floor.
About 16.2% of the Japanese suffer from hay fever. Although self-care is one of the medical treatments of hay fever, and measures against the outdoor pollen usually tend to be regarded as important, measures against the indoor pollen are also important. A great deal of pollen is also contained in indoor dust, which is thought to be involved in aggravation of the symptoms of hay fever or continuation of the stubborn symptoms after termination of flying (refer to Japanese Medical Journal, Vol. 22, 11-17, 2004, non-patent document, “Abstract”).
The above non-patent document reports that it could be revealed that as a result of studying the changing state of indoor cedar pollen after wind-borne cedar pollen counts drop, there is significant cedar pollen indoors on floors (and carpet or tatami mats), sofas, curtains, etc. after the end of the pollen season, that the indoor cedar pollen count is highest in April after the wind-borne pollen counts drop, which decreases gradually but can be detected even in February the following year, that the amount of the suspended indoor cedar pollen is about 1/10 of the amount of cedar pollen on the floor, and that suspended pollen increases as humidity decreases. It is also reported that as a result of measuring the changing state of suspended indoor floating pollen after wind-borne pollen counts drop, few pollen grains were found suspended at a height of 50 cm or more in everyday life.
From the foregoing, it is believed that if water is sprayed from a height of 50 cm or more, substances that cause allergic reactions, i.e., allergens, such as suspended indoor pollen and house dust, can be caused to fall to the floor by being trapped by sprayed water. Furthermore, removing suspended indoor allergens by, for example, wiping away sprayed water on the floor with a disposable cleaning sheet attached to the cleaning head may also be considered.
By way of example, it is believed that since the cleaning implement according to Patent Document 1 is configured to eject water onto the floor from the nozzle on the cleaning head, the effect of removing suspended indoor allergens cannot be anticipated. In addition to the cleaning implement according to Patent Document 1, no cleaning implements for removing suspended indoor allergens with a jet of water from a proper height have been designed until now.
It would be convenient if a cleaning implement were available which were similar to the cleaning implement including a cleaning head as shown in Patent Document 1, and can eject, for example, a wax from the nozzle on the cleaning head and remove suspended indoor allergens with a jet of water from a proper height by changing a container. These are problems to be solved by the present invention.
In order to solve the above problems, an object of the present invention is to provide a cleaning implement including a cleaning head and a pipe attached to the cleaning head and for removing suspended indoor allergens with a jet of water from a proper height.
In order to achieve the above object, the inventors have invented the following new cleaning implement configured such that a valve opening and closing device includes a connection mechanism from which a first container is detachable and an adaptor coupled to the connection mechanism and from which a second container is detachable, in which a first circulation path extends to a first ejection nozzle for ejecting a first fluid from the connection mechanism to the outside of the cleaning head, and a second circulation path extends to a second ejection nozzle for ejecting a second fluid from the adapter.
In a first aspect of the present invention, a cleaning implement includes: a cleaning head having on a bottom a cleaning operation surface; and a pipe coupled to the cleaning head, a fluid spout being located at a distance of about 40 cm or more from the cleaning operation surface to the pipe.
The first aspect of the present invention includes a cleaning head having on a bottom a cleaning operation surface. Also, it includes a pipe coupled to the cleaning head. A fluid spout is located at a distance of about 40 cm or more from the cleaning operation surface to the pipe. By way of example, the fluid spout may be a spout of a second ejection nozzle as will be described later, and fluid ejected from the fluid spout may be a second fluid as will be described later. In the state of using the cleaning implement by being inclined at about 45 degrees, the fluid spout is located at a height of about 30 cm or more from the floor. Then, allergens suspended in the air of a room can be caused to drop by a jet of water from the fluid spout, which can be wiped by the cleaning head.
In a second aspect of the present invention, a cleaning implement includes: a cleaning head having on a bottom a cleaning operation surface; a holding portion arranged on the side opposite the cleaning head; a pipe that couples the cleaning head and the holding portion; and a valve opening and closing device provided to the pipe, the valve opening and closing device being able to hold one of a first container receiving a first fluid and a second container receiving a second fluid, the valve opening and closing device including a connection mechanism from which the first container is detachable and an adaptor coupled to the connection mechanism and from which the second container is detachable, the cleaning head including a first ejection nozzle that ejects the first fluid from the connection mechanism to the outside of the cleaning head, the adapter including a second ejection nozzle that ejects the second fluid from the adapter, the holding portion including a lever coupled to the valve opening and closing device, the lever opening and closing one of the first valve of the first container and the second valve of the second container, in which the spout of the second ejection nozzle is located at a distance of about 40 cm or more from the cleaning operation surface to the pipe.
The second aspect of the present invention includes a cleaning head having on a bottom a cleaning operation surface. Also, it includes a holding portion arranged on the side opposite the cleaning head. A pipe couples the cleaning head and the holding portion. A valve opening and closing device is provided to the pipe. The valve opening and closing device can hold a first container for receiving a first fluid or a second container for receiving a second fluid.
By way of example, the cleaning head may have a cleaning sheet detachably attached to the cleaning operation surface. The pipe may be a holding stem, and may be configured by connecting a plurality of pipes, for example. The valve opening and closing device may not be mounted at a position between the cleaning head and the holding portion, but at a position close to the cleaning head or at a position close to the holding portion. The valve opening and closing device is mounted, preferably, at a position close to the cleaning head. With the first and second containers, either of the two may be mounted to the valve opening and closing device without being both mounted thereto. The valves designate valves of the first and second containers. By actuation of the valve opening and closing device, the first or second fluid is ejected.
According to the second aspect of the present invention, the valve opening and closing device includes a connection mechanism from which the first container is detachable. It also includes an adapter coupled to the connection mechanism and from which the second container is detachable. The cleaning head includes a first ejection nozzle that ejects the first fluid from the connection mechanism to the outside of the cleaning head. The adapter includes a second ejection nozzle that ejects the second fluid from the adapter.
By way of example, provided at the connection mechanism are a cam device and pump, as will be described later, for feeding the first fluid from the first container to the first ejection nozzle side. The valve opening and closing device has a structure that allows the second container in place of the first container to be detached there from through the adapter. A path extending from the connection mechanism to the first ejection nozzle forms the first circulation path through which the first fluid can be ejected from the cleaning head. Furthermore, a path extending from the adapter to the second ejection nozzle forms the second circulation path through which the second fluid can be ejected from the adapter by interrupting the first circulation path.
According to the second aspect of the present invention, the holding portion includes a lever. The lever is coupled to the valve opening and closing device. The lever opens and closes the first valve of the first container or the second valve of the second container.
By way of example, as will be described later, the holding portion includes a pulley rotated in synchronization with rotary motion of the lever. The connection mechanism includes the cam device including a rocker arm forming a dynamic articulation that reciprocates angularly and a pusher following the rocker arm to reciprocate linearly. When the lever is coupled to the valve opening and closing device, a belt may have one end caught at a moving end of the rocker arm and the other end wound on the pulley so as to transmit a displacement of the lever to the pusher. By the adaptor in synchronization with displacement motion of the pusher, the second valve of the second container is opened and closed, for example.
According to the second aspect of the present invention, the spout of the second ejection nozzle is located at a distance of about 40 cm or more from the cleaning operation surface to the pipe.
By way of example, the second fluid may be an atomized wax or a foamed wax. By operating the lever, the second fluid is ejected from the spout of the second ejection nozzle. The service time may be, for example, a state in which the cleaning head is placed on a floor, the holding portion is held by user's hands, and the pipe is operated at an angle of inclination of about 45 degrees. The second fluid is ejected to a space between the cleaning head and the user. The second fluid is ejected in the direction substantially parallel to the pipe, for example. The wording “ejected” includes a case in which the second fluid is diffused like fine spray.
By way of example, in terms of design, the spout of the second ejection nozzle can be located at a distance of about 28 to 141 cm from the cleaning operation surface to the pipe. Specifically, in the service state that the pipe is operated at an angle of inclination of about 45 degrees, the spout of the second ejection nozzle can be located at 20 to 100 cm from the floor. If the spout of the second ejection nozzle is close to the holding portion, i.e., if the spout of the second ejection nozzle is at a high position from the floor, for example, the probability that the second fluid will be sprinkled on user's feet becomes undesirably higher. If the spout of the second ejection nozzle is close to the cleaning head, i.e., if the spout of the second ejection nozzle is at a low position of about 20 cm from the floor, for example, it is deemed that an effect involved in removal of allergens at which the present invention aims is undesirably reduced. The spout of the second ejection nozzle is located, preferably, at a height of about 30 cm or more from the floor during the service. Then, the second fluid containing removed allergens can be wiped away by the cleaning head.
The second aspect of the present invention is a cleaning implement including a cleaning head, in which a wax, for example, can be ejected from the first ejection nozzle on the cleaning head, and in which by changing a container, allergens suspended in the air of a room can be caused to fall to the floor by a jet of water, and the second fluid containing allergens can be wiped by the cleaning head.
In a third aspect of the present invention, a cleaning implement according to the second aspect of the present invention is one in which the connection mechanism is connected to the first valve of the first container.
According to the third aspect of the present invention, since the first valve of the first container is operated directly, the mechanism of the cleaning implement can be simplified, resulting in cost reduction of the cleaning implement.
In a fourth aspect of the present invention, a cleaning implement according to the second or third aspect of the present invention is one in which the first container is of a type of a bottle, and the bottle is moved in the direction parallel to an axis of the first valve so as to drop the first fluid naturally.
According to the fourth aspect of the present invention, since the first container can be of a type of a commercially available bottle, the first container ensuring natural dropping of the first fluid suitable for cleaning can be mounted to the cleaning implement.
In a fifth aspect of the present invention, a cleaning implement according to any one of the second to fourth aspects is one in which the second ejection nozzle is connected to the second valve of the second container.
According to the fifth aspect of the present invention, since the second ejection nozzle is directly connected to the second valve, the mechanism of the cleaning implement can be simplified, resulting in cost reduction of the cleaning implement.
In a sixth aspect of the present invention, a cleaning implement according to any one of the second to fifth aspects of the present invention is one in which the second container is a tilt-type spray can, the tilt-type spray can be tilted in the direction orthogonal to an axis of the second valve so as to eject the second fluid.
According to the sixth aspect of the present invention, since a tilt-type spray can for receiving a solution suitable for removal of allergens can be mounted to the cleaning implement, for example, the second fluid suitable for removal of allergens can be used easily.
In a seventh aspect of the present invention, a cleaning implement according to any one of the second to sixth aspects of the present invention is one in which, the connection mechanism includes a cam device including a rocker arm forming a dynamic articulation that reciprocates angularly and a pusher following the rocker arm to reciprocate linearly, the holding portion includes a pulley rotated in synchronization with rotary motion of the lever and a belt having an end caught at a moving end of the rocker arm and the other end wound on the pulley, and the belt transmits a displacement of the lever to the pusher.
According to the seventh aspect of the present invention, the belt may be used as a means for transmitting motion of the lever of the holding portion to the rocker arm of the connection mechanism, providing excellent flexibility. Thus, even if an articulation part exists between the holding portion and the connection mechanism, motion of the lever of the holding portion can surely be transmitted to the rocker arm.
In an eighth aspect of the present invention, a cleaning implement according to the seventh aspect of the present invention is one in which the adaptor includes a cylindrical adaptor main body, a cylinder held inside the adaptor main body to be movable axially and the second ejection nozzle coupled to the cylinder, the adaptor main body has an end having a first connection port detachably held to the connection mechanism and another end having a second connection port for detachably holding the second container, the cylinder has an end abutting on a distal end of the pusher toward the first connection port and another end having an inclined portion that intersects the axial direction of the cylinder at an acute angle toward the second connection port, in which the second ejection nozzle is formed in a T-shape, the T-shaped second ejection nozzle has an end coupled to the inclined portion and another end connected to the second valve, the T-shaped second ejection nozzle has at a T-shaped end provided a spout for ejecting the second fluid to the outside of the adaptor main body.
According to the eighth aspect of the present invention, the adapter includes a cylindrical adapter main body. It also includes a cylinder movably held inside the adaptor main body to be movable axially. It further includes the second ejection nozzle coupled to the cylinder. The adaptor main body has one end having a first connection port detachably held to the connection mechanism and the other end having a second connection port for detachably holding the second container.
According to the eighth aspect of the present invention, the cylinder has one end abutting on a distal end of the pusher toward the first connection port. The other end has an inclined portion that intersects the axial direction of the cylinder at an acute angle toward the second connection port. The second ejection nozzle is formed in a T-shape, and the T-shaped second ejection nozzle has one end coupled to the inclined portion. The other end is connected to the second valve. The T-shaped second ejection nozzle has a spout for ejecting the second fluid to the outside of the adaptor main body at a T-shaped end.
A weight reduction can be achieved, for example, by molding out of a synthetic resin the adapter main body, cylinder, and second ejection nozzle that are components of the adapter. The adapter may be mounted to the valve opening and closing device in place of the first container. When operating the lever, movement of the pusher is transmitted to the cylinder. When the cylinder is moved, the inclined portion at the other end of the cylinder operates to tilt the second ejection nozzle. The second fluid is supplied from the second container to the second ejection nozzle. On the other hand, when releasing the lever, the pusher returns to the position, and the cylinder returns to the pusher side in synchronization with returning of a tilting posture of the second ejection nozzle. While the cylinder reciprocates, an angle of the inclined portion is, preferably, in the range of 30 to 60 degrees. Thus, the cleaning implement of the present invention can eject allergen-removing water as appropriate by operating the lever.
In a ninth aspect of the present invention, a cleaning implement according to the eighth aspect of the present invention is one in which the cylinder includes a pair of side walls arranged on both sides of the inclined portion with a space, and the second valve has a part arranged in the space.
A distal end of the second valve is coupled by being restrained by the pair of side walls in the ninth aspect of the present invention.

It further includes the second ejection nozzle coupled to the cylinder. The adaptor main body has one end having a first connection port detachably held to the connection mechanism and the other end having a second connection port for detachably holding the second container.
According to the tenth aspect of the present invention, the second ejection nozzle includes an L-shaped portion and a collar formed with the L-shaped portion and extending in the direction orthogonal to the axis of the second valve. The cylinder has one end abutting on a distal end of the pusher toward the first connection port and the other end having a protrusion that can push the collar in a position distant from the second valve. The L-shaped portion has one end coupled to the second valve and the other end formed with a spout for ejecting the second fluid to the outside of the adaptor main body.
According to the tenth aspect of the present invention having a structure different from that of the eighth aspect of the present invention, the second ejection nozzle is tilted based on the principle of leverage.
In an eleventh aspect of the present invention, a cleaning implement according to any one of the second to fourth and seventh to tenth aspects of the present invention is one in which the first fluid is one of water, a liquid detergent, and a liquid wax.

The pump 36 has a shape having a U-shaped section with one end opened. An opening 36a at one end of the pump 36 is hermetically connected to a frame 31a of the connection mechanism 31. A hole 36b is formed at the other end (bottom) of the pump 36. The hole 36b is hermetically connected to one end of a hose 4 that defines a first circulation path. The other end of the hose 4 is hermetically connected to the first ejection nozzle 23 through the inside of the pipe 8.

The rocker arm 34 reciprocates angularly with a pivot 31b provided to the frame 31a as center of rotation. The other end 73a of the belt 73 is caught at a moving end 34a of the rocker arm 34. Therefore, the belt 73 extending from the pulley 74 passes through the inside of the pipe members 8b to 8d to be caught at the moving end 34. The convex 34b (refer to

The internal structure of the cap 90 will be described. As shown in
As shown in
The first ring member 92 includes a circular ring packing. The first ring member 92 seals the first fluid charged in the first container 61. The first valve 93 includes a head 93a and a leg 93b. The head 93a includes a cylindrical head main body and a pair of flanges arranged on both sides of the head main body. The first ring member 92 is arranged between the flanges, i.e., on the peripheral face of the head main body. One end of the head 93a is formed with an insertion hole into which one end of the pusher 35 is inserted. The other end of the head 93a is formed with the leg 93b. The leg 93b includes four blades. Each blade is formed with a convex for catching the compression coil spring 94. One end of the compression coil spring 94 is caught in a catch groove 96e as will be described later. On the other hand, the other end of the compression coil spring 94 is caught at the convex.
As shown in
The seal member 97 includes a flange 97a as shown in
The tube member 98 has a columnar shape. The section of the tube member 98 is shaped like a ring to allow air from the air hole 91d to flow into the tank 61b. One end of the tube member 98 is engaged with the long tube 96c. The tube member 98 is formed out of polyurethane (PU) resin. The valve protection member 99 is shaped like a bell. A horn portion 99a having an apex as engaged is arranged at an upper end of the valve protection member 99. The horn portion 99a is engaged with the other end of the tube member 98. The top of the valve protection member 99 includes a pair of recesses 99b. A convex (not shown) having a through hole engaging with the valve member 100 is arranged in the valve protection member 99. The valve member 100 is arranged in the valve protection member 99.
The valve member 100 includes a valve main body 100a and a flange 100b. The valve main body 100a is shaped substantially cylindrically. The valve main body 100a is formed out of a resilient member. A distal end 100c of the valve main body 100a has a cut shape obtained by cutting the cylindrical shape from both side faces thereof. It is noted that the cut shape is such that two plate-shaped valves are arranged to be superimposed one upon another at the distal end, and are constructed to open or close in substantially the center of the distal end. With such a construction, the distal end 100c allows the valves to open in substantially the center so that air from the air hole 91d is fed to the tank 61b through the tube member 98. A flange 100b is arranged at the other end of the valve main body 100a.
With the above structure, the first valve 93 is biased by the compression coil spring 94 from the inside of the cap 90, thereby obtaining the closed state of the valve hole 91a.
When the first container 61 is mounted to the connection mechanism 31, the outer periphery of the cap 90 makes close contact with the pump 36 hermetically, whereas the first valve 93 of the first container 61 is pressed to the distal end 35a against a biasing force of the compression coil spring 94. At this time, the first valve 93 of the first container 61 is slightly moved toward the tank 61b. However, no clearance allowing part of the first fluid received in the first container 61 to flow out toward a space defined by the pump 36 and the first valve 93 is formed between the first valve 93 and the valve hole 91a.
As a result, part of the first fluid received in the first container 61 does not flow out toward a space defined by the pump 36 and the first valve 93. Moreover, since the hole 36b is closed by the pump 36 and the pusher 35, the first fluid in the first container 61 is not moved into the hose 4 in this state.
On the other hand, when the user pulls the lever 71, the belt 73 is moved to the holding portion 7 so that the rocker arm 34 is rotated by a pulling force of the belt 73. Furthermore, since the pusher 35 is linearly moved to the holding portion 7, the first valve 93 of the first container 61 is moved in the direction of the tank 61b, and the collar 35b is moved in the direction of separating from the hole 36b of the pump 36. Therefore, concurrently with a clearance being produced between the collar 35b and the hole 36b, air taken in from the air hole 91d is supplied into the tank 61b through the tube member 98 and the valve member 100. With this, the first fluid in the first container 61 is supplied to the first ejection nozzle 23 through this clearance and the hose 4. The supplied first fluid is ejected forward of the cleaning head 2 from the first ejection nozzle 23. That is, the first fluid passes through the first circulation path.

The second container 62 is mounted to the adaptor main body 32a on the side of the second connection port 32d. The second container 32 is a spray can include a tilt-type valve that is tilted in the direction orthogonal to an axis of the second valve 62a so as to eject the second fluid received in the second container 62. Therefore, when the second ejection nozzle 51 is tilted, the second fluid is ejected from the spout 51c. Moreover, since the spout 51c is positioned at the height H from the floor surface F, the second fluid ejected from the spout 51c may be a fluid of lower viscosity such water as well as a fluid of higher viscosity such as foam.
By way of example, the first container 61 may be of a type of a bottle that is moved in the direction parallel to an axis of the first valve 93 (refer to
When the user pulls the lever 71, the lever 71 is pushed into the holding portion 7 against a biasing force of the torsion coil spring 75, rotating the gear 71a. With this, the gear 74a is rotated together with the pulley 74 to wind the belt 73. When the belt 73 is wound on the pulley 74, the pusher 35 moves the cylinder 32b to the second container 62.
When the cylinder 32b is moved to the second container 62, the inclined portion 32e tilts the second ejection nozzle 51 in the direction of orthogonal to the moving direction of the cylinder 32b. With this, referring to
When the user stops pulling the lever 71, the lever 71 rotates the pulley 74 in the direction of loosing the belt 73 by a biasing force of the torsion coil spring 75. With this, the pusher 35 is moved in the direction away from the cylinder 32b, providing no force of pushing the cylinder 32b. Furthermore, a returning force of the second valve 62a of the second container 62 acts on the inclined portion 32e of the cylinder 32b. Then, the cylinder 32b is moved in the direction away from the second container 62. Thus, the inclination of the second valve 62a with respect to the second container 62 returns to the vertical state, stopping ejection of the second fluid from the second ejection nozzle 51.
In another embodiment as shown in
The surface with which the protrusion 32h makes contact is separated from a center P of rotation on which the second valve 62a tilts by a distance h in the axial direction. The protrusion 32h makes contact with the collar 51f spaced with respect to the second valve 62a in the direction away from the axial direction. As a result, reciprocation of the cylinder 32b is converted into rotation with the center P of rotation as center so that the second valve 62a is tilted by this rotation by an angle α.

The adaptor 120 includes a cylindrical adaptor main body 130, a cylinder 140 axially movably held in the adaptor main body 130, and a third ejection nozzle 150 coupled to the cylinder 140. The third ejection nozzle 150 serves as a third circulation path through which the third fluid flows.

Since one end of the adaptor main body 130 has substantially the same shape as that of the cap 90 of the first container 61, it can be fitted in the pump 36 of the connection mechanism 31 so that the adaptor main body 130 is held by the connection mechanism 31.
Referring to
When the user pulls the lever 71, the lever 71 is pushed into the holding portion 7 against a biasing force of the torsion coil spring 75, rotating the gear 71a. With this, the gear 74a is rotated together with the pulley 74 to wind the belt 73. When the belt 73 is wound on the pulley 74, the pusher 35 pushes the convex 146a formed in the collar 146 of the cylinder 140, moving the cylinder 140 to the third container 63.
Referring to
Therefore, referring to
Referring to
In the drawing, points P1 and P2 correspond to the case in which an angle between the floor F and the pipe 8 is 45 degrees. The point P1 designates a content landing point when pulling the lever 71 slightly so that the third valve 63a just begins to open, whereas the point P2 designates a content landing point when pulling the lever 71 maximally so that the third valve 63a opens to the maximum extent.
When the user stops pulling the lever 71, the lever 71 rotates the pulley 74 in the direction of loosening the belt 73 by a biasing force of the torsion coil spring 75. With this, the pusher 35 is moved in the direction away from the cylinder 140, providing no force of pushing the cylinder 140. Furthermore, a returning force of the third valve 63a of the third container 63 acts on the pair of pressing portions 148a and 148b of the cylinder 140. Then, the cylinder 140 is moved in the direction away from the third container 63. Thus, the inclination of the third valve 63a with respect to the third container 63 returns to the vertical state, stopping ejection of the third fluid from the third ejection nozzle 150.
