Abstract

PROBLEM TO BE SOLVED: To enable dirt stuck to an input-operating part of an office autiomation appliance, a computer, or a home appliance to be removed quickly and securely by a simple work by floating the dirt and removing the dirt through a liquid-applied part, while applying liquid with which the liquid-applied part is impregnated to a portion to be cleaned. SOLUTION: Liquid impregnated in cotton 5 inside a storage part 2 of a cleaner body 1 is drawn out by capillary phenomena to permeate through the whole of a scraper 7. Wherein in the case of removing dirt stuck to a roller rotatably set on an axis inside a case of a mouse, a cap 8 is removed from the cleaner body 1, and the scraper 7 is pushed against the dirt of the roller, and the liquid contained in the scraper 7 is rubbed to the dirt while the liquid contained in the scraper 7 is applied to the dirt. The dirt is softened by dissolving action of the liquid and floats from the surface of the roller. The dirt is easily scraped off because the hardness of the scraper 7 is slightly lower than that of the roller.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to OA equipment, AV
The present invention relates to a cleaner for removing sebum dirt and dust adhering to an input operation unit of a device, a computer, or a home appliance, and particularly to a cleaner suitable for removing dirt in details.

[0002]

2. Description of the Related Art There are various types of devices such as a keyboard, a light pen, and a mouse for performing input operations on a computer or the like. Among them, a mouse is relatively easy for an unskilled person to perform. Most computers are equipped with a connection terminal,
It is considered indispensable for personal computers. As is well known, in this mouse, a signal is input to a computer or the like by rotating a rotating ball partially exposed from an opening formed in a bottom surface. As shown in FIG. B can be taken out from the opening C1a of the housing C by removing an annular lid C2 detachably provided on the bottom C1 of the housing C of the mouse M. In addition, a plurality of rollers R (see FIG. 7) which are pivotally mounted inside the housing C come into contact with the outer periphery of the rotating ball B, and the rotating roller R also rotates with the rotation of the rotating ball B. They are designed to rotate together.

At the time of input operation, the bottom surface C1
Is held downward, the housing R is rotated together with the rotating ball B by moving the housing C1 while contacting the rotating ball B with the upper surface of the table or the like, and the signal is output according to the amount and direction of the rotation of the roller R. Is output, and the signal is input to the computer via the cable. Therefore, in order to maintain the operation accuracy and smoothness of the mouse M, it is necessary to maintain good contact between the roller R and the rotating ball B.
There is a problem that dust and the like on the table, which are entrained by, etc., are strongly adhered and easily stained, and the contact between the rotating ball B and the roller R is not properly maintained due to the stain.
There is a disadvantage that the roller R does not sufficiently follow the rotation of the rotating ball B, causing a malfunction or a decrease in operability. For this reason, in the mouse M, it is necessary to periodically remove the dirt from the roller R. Conventionally, this operation has been performed by rubbing off with a swab S, felt, or a toothpick.

[0004]

However, when the dirt is removed using the dirt attached to the roller R, the above-mentioned swab S or felt is too soft, so that the hard dirt attached to the roller R is hard to remove. Even if it falls, dust separated from the roller R may enter the inside of the mouse M and cause a malfunction. Conversely, if a sharp object such as a toothpick is used, there is a problem that the roller R is damaged.

On the other hand, at present, a cleaner for removing dirt from a mouse, a keyboard, a switch, a button and the like has been proposed and implemented. This cleaner is roughly classified into two types: one that uses a solvent for removing dirt and one that does not use it. For those that do not use a solvent, a spherical felt is supported on the main body, and this is rubbed to remove dirt. Things are generally known. Further, as a solvent using a solvent, a scraper having a tip portion formed of a material that can be impregnated with a solvent and a scraper in which a solvent is stored in a container separate from the scraper are known as a set. ing. The cleaner presses a scraper containing a liquid against dirt, and removes the dirt while floating the dirt by the action of the liquid.

However, a cleaner that does not use a solvent has such a degree that a spherical felt can be easily applied to a roller, and there is almost no difference in the ability to remove dirt from a cotton swab or the like. In the case of using a solvent,
It is inconvenient to use because the scraper must be immersed in the solvent in the container each time it is used, and the scraper is provided for the purpose of sweeping off the dirt raised by the solvent. Since it does not have the ability to scrape off dirt by itself, it is necessary to use a solvent for floating the dirt over a long period of time, which is time-consuming and requires a large amount of solvent. Although it is conceivable to use a special solvent having the best ability to remove dirt, it is expensive and causes a problem in cost. It is also conceivable to use simple water as a solvent,
In this case, it is difficult to remove the dirt because the dirt does not rise, and since the dirt is low in volatility, it takes a long time until the portion wet by the solvent is sufficiently dried after use, and there is a problem that the use cannot be resumed immediately. .

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and can quickly and reliably remove dirt adhering to an input operation unit of an OA device, a computer, and a home appliance by a simple operation. The purpose is to provide a cleaner.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a half sectional view according to the first embodiment of the present invention. In the figure, 1 is a cleaner body (liquid tank) formed of polypropylene,
A cylindrical storage part 2 and a tapered holding part 3 formed at the tip of the storage part 2 are integrally formed. An opening (liquid discharge port) is formed at the rear end of the storage part 2. Exit) 2
a is formed. The inside of the cleaner body 1 is filled with a stick-shaped acrylic batting 4 which is impregnated with a relatively low-viscosity solution using at least one of ethanol and IPA (isopropyl alcohol). Have been. A tail plug 6 is press-fitted into an opening 2 formed at the rear end of the cleaner main body 1 so as to close the opening 2 formed at the rear. A plurality of (here, four) ribs 6a are formed on the inner surface of the tail plug 6, and when inserting the batting 5 into the cleaner main body 1, the rear end of the batting 5 is pressed by the rib 6a. While pushing forward.

The holding portion 3 comprises an inclined portion 3a having a shape of a truncated cone, and a small-diameter cylindrical portion 3b formed at the tip of the inclined portion 3a. The inner surface of the cylindrical portion 3b has a longitudinal direction. (Here, three) ventilation grooves G1 along
Are formed, whereby a plurality of (here, three) holding surfaces 3d are formed, and at the rear end of each holding surface 3d, an arc-shaped engaging protrusion 3e protruding inward is formed. Each is formed along the same circumference. Also, a plurality of ribs 4 are protruded from the inner surface of the inclined portion 3a to the inner surface of the front portion of the cleaner body 1. The rib 4 is formed with a step 4a. The front end of the batting 5 inserted into the cleaner main body 1 is locked by the step 4a, and the rib 4 located on the cleaner main body 1 side is filled with the batting. 5
And the batting 5 is held in a fixed position.

On the other hand, the cylindrical portion 3b of the cleaner main body 1
Inside, a scraper 7 as a liquid application unit is held. The scraper 7 is made of a material capable of containing the above-mentioned liquid, for example, a resin or fiber material.
b is formed in a rod shape so as to have substantially the same diameter, and its front and rear end portions have a so-called shell shape in which the cross-sectional shape is reduced in diameter toward the outside, and an annular groove portion is provided at an intermediate portion thereof. 7c is formed. By inserting the scraper 7 into the cylindrical portion 3b of the cleaner main body 1, the scraper 7 is pressed against each of the holding surfaces 3d,
The projection 3e formed on the groove d is adapted to engage with the groove 7c, so that it can be prevented from being accidentally pulled out of the cylindrical portion 3b. Further, with the scraper 7 held in the cylindrical portion 3b, the front end portion 7a is
b protrudes forward from the front end, and the rear end is inserted into the front of the batting 5. In addition, 8
Is a cap that covers the scraper 7, and the cleaner body 1
The scraper 7 can be detachably engaged with the holding portion 3, and the scraper 7 is shut off from the external space when the device is mounted, so that the liquid can be prevented from being unnecessarily evaporated.

The scraper 7 is a spring-type hardness tester (A type described in "5.2 Spring-type hardness tester" in JIS K6301-1975 (flow rubber physical test method)). Has a hardness that falls within the range of 10 to 99 on the scale, and is lower than the portion to be cleaned. For example, when the portion to be cleaned is the roller R of the mouse M used when performing an input operation to the computer, the scraper 7 has a lower hardness than the roller R in the above range. In addition, this measured value is measured with the flat end face of the raw bar before polishing of the scraper 7 as a measuring surface, keeping the tester vertical, and bringing the indenter into contact with the pressing surface so that the indenter is perpendicular to the measuring surface. It is the value obtained by reading.

In the cleaner (mouth cleaner) configured as described above, since the scraper 7 is inserted into the batting 5 stored in the storage part 2 of the cleaner main body 1, the batting 5 is impregnated. The liquid is sucked out by capillary action and permeates the entire scraper 7. Therefore, the scraper 7 always contains liquid as long as the batting 5 contains liquid. Here, in order to remove the dirt attached to the roller R mounted inside the housing C of the mouse M as shown in FIG. 6, the cap 8 is removed from the cleaner main body 1 and the scraper 7 is removed by the roller. R is pressed against the dirt, and the scraper 7 is rubbed while applying the liquid contained in the scraper 7 to the dirt. At this time, the dirt is softened by the dissolving action of the liquid and floats from the surface of the roller R, and the dirt is easily scraped off by the scraper 7 because the scraper 7 has a hardness slightly lower than that of the roller R. Is done. In addition, since the scraper 7 has a lower hardness than the roller R, the roller R is not damaged when scraped off, and a good smooth surface can be always maintained.

Further, since the liquid used here has higher volatility than water, after the dirt is removed as described above, the liquid dries in a short time and the input operation by the mouse M is immediately performed. Can be resumed. When the liquid is consumed by the scraper 7, the air flows into the main body 1 from the ventilation groove 3c accordingly, and the gas-liquid replacement operation is performed.
Since the air can flow from the ventilation groove 3c in this manner, even if the scraper 7 is swollen by the liquid, the gas-liquid replacement operation is performed reliably.

Further, in the mouth cleaner according to the first embodiment, since the front end 7a of the scraper 7 has a shell shape, minute dirt on the roller R can be easily removed. In addition, since the pad shown here uses a batting to hold the liquid, it does not require very strict accuracy in liquid tightness of the cleaner body 1 and the like, and is composed of a very small number of parts, such as five parts. Therefore, it can be configured at low cost. Further, the scraper 7 is held by pressing against the holding surface 3d of the cleaner main body 1 and engaging with the projection 3e.
Since it is not firmly fixed, it can be easily pulled out from the cylindrical portion 3b. For this reason,
If a plurality of scrapers 7 are prepared in advance, the used scrapers 7 can be replaced with new ones when they become dirty, and can be used extremely hygienically. It is possible to completely use up the liquid regardless of the state of 7, and the liquid is not wasted.

Further, since the scraper 7 is made of resin or fiber, fine dirt scraped off by the scraper 7 can be adsorbed and impregnated in the scraper, so that fine dirt is not scattered inside the mouse. Furthermore, when all the liquid in the batting 5 has been consumed, the tail plug 6 is pulled out from the main body, the batting 5 is taken out from the opening 2a, and a new one can be attached to supply the liquid.

Next, a second embodiment of the present invention will be described with reference to FIG. In FIG. 2, reference numeral 11 denotes a cylindrical cleaner body (liquid tank) having a bottom. An opening (liquid discharge port) 12a is formed in a front portion 12 thereof, and a screw portion 12b is formed in a peripheral surface thereof. The opening 12a

The contact portion 16a of the valve rod 16 is pressed against the rear end opening of the valve seat 15 by the force to keep the opening closed, and the valve seat 15 is closed.
And the space behind it is cut off.

The tip shaft 18 has a cylindrical portion 18a formed at its tip and a screw portion 18b which is screwed with a screw portion 11b of the cleaner main body 11 at the rear inner surface. By screwing the screw portion 18b into the screw portion 12b, a front end of the valve seat 15 is formed between the locking step portion 18c formed on the inner surface of the front shaft 18 and the opening portion 12a of the cleaner body 11. The fixed flange 15a and the flange 14a of the spring receiver 14 are clamped and fixed, and the valve mechanism 1
3 is held in the cleaner main body 11. A cylindrical sponge 19 is inserted into the space formed between the front end of the valve mechanism 13 and the front shaft 18 for holding the liquid.

A scraper 20 as a liquid application unit is inserted into the cylindrical portion 18a of the front shaft 18.
The scraper 20 is made of the same material as that of the first embodiment in a cylindrical shape. The front end portion 20a protruding from the front end of the front shaft 18a has a circular cross-sectional shape that decreases in diameter toward the front. It has a so-called shell shape. Also, a plurality of (here, six) ribs 18a1 are formed on the inner surface of the cylindrical portion 18a along the axial direction, and the scraper 20 is held so as not to be accidentally pulled out by the pressure contact with the ribs 18a1. Have been. Also,
The rear end 20b of the scraper 20 contacts the front end of the valve stem 16 and the rear peripheral surface contacts the inner surface of the sponge 19. Further, the scraper 20 is provided with the first
And is formed with a lower hardness than the roller R provided on the mouse M. Reference numeral 21 denotes a steel ball for stirring the liquid contained in the cleaner main body 11, and reference numeral 22 denotes a cap that covers the front end of the front shaft 18 and the scraper 20, and is detachable from the outer peripheral surface of the front shaft 18. It has become.

In the cleaner having the above-described structure, the scraper 20 includes the cylindrical portion 18a of the front shaft 18 and the sponge 19.
2 and is prevented from falling off even when it is directed downward, and the front end portion 20a is always in a protruding state as shown by a solid line in FIG. In this state, the contact portion 16a of the valve rod 16 closes the rear end opening of the valve seat 15 by the urging force of the spring 17, so that the supply of the liquid stored in the main body 11 to the scraper 20 is cut off. Have been.

If the scraper 20 is not sufficiently impregnated with the liquid when using the mouth cleaner according to this embodiment, first, the scraper 20 is brought into contact with the roller R or the like of the mouse M while the scraper 20 is in contact with the cleaner. Body 11
Is pressed toward the roller R, and the scraper 20 is pushed inward (rearward) of the scraper 20 together with the valve rod 16 against the spring 17. Then, the opening / closing portion 16a of the valve stem 16 is moved to the valve seat 1
5 and is separated from the rear end opening, and the space before and after the valve seat 15 is brought into a communicating state. Therefore, the liquid L stored in the cleaner main body 11 flows into the valve seat 15 from the window hole 14b formed in the side surface of the spring receiver 14, and the sponge 1
9 and is supplied to the scraper 20 by infiltration. Further, since the scraper 20 is held by the rib 18a1 formed on the cylindrical portion 18a, a portion of the cylindrical portion 18a other than the rib 18a1 is
0, a ventilation groove G2 communicating with the external space in front of the front shaft 18 is formed, and this serves as an air flow passage communicating with the inside of the spring receiver via the sponge 19. Therefore, even if the scraper 20 swells, the air corresponding to the liquid consumption flows into the cleaner main body 11 smoothly through the ventilation groove G2, so that the liquid can flow out smoothly.

Thus, the liquid L is applied to the scraper 20.
, And the liquid L is pressed against the roller R
The dirt is applied to the surface of the roller R to lift the dirt.
Then, if the scraper 20 is pressed against the dirt and rubbed, the dirt softened by the liquid L and lifted up is surely scraped off by the scraper 20 having an appropriate hardness.
Since it is adsorbed and impregnated into the mouse, fine dirt is not scattered in the mouse. Further, since the scraper 20 is formed to have a lower hardness than the roller R, there is no possibility that the roller R is damaged. Also, in this embodiment, the scraper 2
By pressing and releasing 0 and moving it within the front shaft 18, the supply and cutoff of the liquid L can be appropriately performed.
At the time of use, an appropriate amount of liquid L
And the liquid in the cleaner body 11 does not flow out to the scraper 20 and volatilizes even if the cap 22 is left in a detached state, and the liquid L is consumed wastefully. Can be prevented.

The inner tip shaft 48 is inserted so that the convex portion 41A formed at the rear end thereof rides over the convex portions 31A and 31B formed on the inner peripheral surface of the outer shaft 31 and is located forward of the convex portions 31A and 31B. Withdrawal of the inner shaft 40 due to its own weight or swinging is prevented by the contact between the convex portion 31A and the convex portion 41A.

The liquid guide tube 34 is inserted into the inner tip shaft 48 and the valve mechanism 42, and the rear end of the liquid guide tube 34 is pressed against the front end of the valve rod 46, and a spring is provided. 47 is in a compressed state. That is, the spring 47 prevents the valve shaft 46 from moving forward with respect to the outer shaft 31 via the liquid guide tube 34 and the rearward movement with respect to the outer shaft 31 via the inner tip shaft 48 and the like. Spring support 4
2 in a compressed state. Therefore, the convex portion 41A of the inner tip shaft 48 is always in a state of being pressed against and locked to the convex portion 31A. 49 is the inner shaft 48
Is a ring-shaped packing inserted between the valve seat 43 and the liquid guide tube 34 to maintain liquid tightness when the valve seat 43 and the liquid guide tube 34 slide. Reference numeral 50 denotes a cap for covering the scraper 38, which is press-fitted into the peripheral surface of the front shaft 36 so as to be insertable and removable.

In the mouth cleaner having the above structure, when the convex portion 41A of the inner shaft 48 is in contact with the convex portion 31A of the outer shaft 31, the inner shaft 40 has a rear end portion as shown by a solid line. It is at a position coinciding with the rearmost end of the outer shaft 31. However, a part of the rear end of the inner shaft 40 is exposed to the outside from the opening 31a of the outer shaft 31 which is notched forward. At this time, the valve seat 43 of the valve mechanism 42 has the opening 43b formed at the rear end thereof closed by the contact portion 46a of the valve rod 46, and the inflow port 34c.
Is completely covered, so that the inner shaft 40
The communication between the internal space and the liquid guide tube 34 is blocked, and the outflow of the liquid in the inner shaft 40 is prevented.

When a finger is put on the rear end of the inner shaft 40 exposed to the outside and pressed forward, the inner shaft 40 presses and compresses the spring 47 together with the valve seat 43 and the spring receiver 42 while contracting the outer shaft. It moves forward with respect to 31. At this time, since the valve stem 46 is held at a fixed position together with the liquid guide pipe 34, the rear end opening 43b of the valve seat 43 is separated from the contact portion 46a of the valve stem 46 to be opened, and the liquid The opening 34c of the guide tube 34 is also opened. As a result, the inner shaft 40 and the liquid guide tube 34 are in communication with each other, and the liquid stored in the inner shaft 40 flows to the flow path 34b of the liquid guide tube 34 due to its own weight or swinging motion by the user. And is supplied to the scraper 38 through the opening 35b of the seal ring 35. When the pressing of the inner shaft 40 is released, the inner shaft 40 and the valve seat 43 return to the initial position by the urging force of the spring 47, and the valve seat 43 is
Since the valve 4c is closed and the valve rod 46 closes the rear end opening 43b of the valve seat 43, the outflow of the liquid L from the inner shaft 40 is shut off.

As described above, in the third embodiment, the supply of the liquid L to the scraper 38 can be performed by a so-called knocking operation of pressing and releasing the inner shaft 40 housed in the outer shaft 31. The supply amount can be obtained without excess or deficiency as needed. Also, if the user pulls the inner shaft 40 strongly, the inner shaft 40 is deformed due to the flexibility or the like, and the protrusion 41
Since A gets over the convex portions 31A and 31B, it can be removed from the outer shaft 31. Therefore, when all the liquid L in the inner shaft 40 has been consumed, the inner shaft 40 may be taken out and replenished with the liquid L, and the inner shaft 40 can be used repeatedly, which is economical. In addition, when storing the liquid in the inner shaft 40, after unscrewing the inner tip shaft 41 from the small diameter portion 33 of the outer shaft 31 and removing the same, the valve mechanism 42 is pulled out.
The liquid L may be injected from the opening 41a of the inner shaft 40.

In the third embodiment,
When the scraper 38 becomes dirty as in the first and second embodiments, the scraper 38 can be pulled out from the cylindrical portion 36a of the front shaft 36, and can be easily replaced with a new one. However, in the third embodiment, it is not necessary to move the front shaft 36 in the axial direction when supplying the liquid L as in the second embodiment, so that the scraper 38 is held with a relatively large holding force. It is made to let. For this reason, since the holding force is increased, it takes more force to remove and insert the scraper than in the second embodiment at the time of replacement. However, even if the scraper 38 is rubbed against the roller R of the mouse M violently, the scraper 38 is in a cylindrical shape. It does not come off from the portion 36a and is suitable for scraping off dirt more firmly attached.

Since the hardness of the scraper is set in the range of 10 to 99 measured scale values in the spring hardness meter as in the first or second embodiment, there is no possibility that the roller is damaged. Also, when the dirt is scraped off, the dirt can be reliably stripped off without being too soft and having a weak waist. Then, the scraped fine dirt is adsorbed and impregnated in the scraper. And this third
Since the scraper 38 in the embodiment has a chisel shape, if dirt is adhered over a relatively large area, it can be efficiently removed.

The chisel-shaped scraper 38
Is also applicable to the first and second embodiments. Further, the above embodiments are not limited to the shell shape and the chisel shape, and scrapers having other various shapes can be applied. Further, the liquid application section is not limited to the case where the hardness is set within the above range (measurement scale of 10 to 99 by a spring hardness meter), and a liquid having a lower hardness than the above range can be used. In this case, the function as a scraper for scraping off the dirt on the liquid applicator cannot be obtained, but the dirt raised by the cleaning liquid can be easily removed by wiping it off with a tissue paper or the like. In the first embodiment, since the liquid is stored in a state where the batting is impregnated with the liquid, it is desirable that the viscosity of the liquid is relatively low. However, the second and third embodiments are preferable. Since the raw liquid is stored directly in the cleaner main body 11 or the inner shaft 40, the liquid can be applied in a wide range from low viscosity to relatively high viscosity.

Further, in the above embodiment, the so-called mouse cleaner for removing dirt attached to the roller of the mouse has been described as an example. However, dirt other than the mouse cleaner can be removed. The present invention is not limited to the above embodiment. For example, the cleaner of the present invention is also suitable for removing dirt from a portion to which sebum dirt or dust easily adheres, such as a keyboard of an OA device, a remote control of an AV device, or a home appliance. In addition, if the liquid application section is made thinner and longer and ethanol is used as the main component of the cleaning liquid, it can be used for cleaning a print head used in a word processor or the like. Also, if the main component of the cleaning liquid is mineral spirit, it is possible to peel off the seal portion or to remove oil-based ink, and the present invention is particularly limited to the above embodiment. Not something.
