BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water purifying function which is attached to a hose-shaped water outlet such as a bathroom or a wash basin to remove residual chlorine and the like contained in raw water such as tap water and to discharge purified water like a shower. The present invention relates to an attached shower head and its shower nozzle.

[0002]

2. Description of the Related Art In recent years, awareness of health and beauty has been increasing. Regarding residual chlorine in tap water, such residual chlorine damages hair and damages skin not only for drinking but also for bathing and face washing. It is desired to remove this residual chlorine from tap water for irritation and to give discomfort due to the smell of chlorine. In response to such a demand, a shower head with a water purification function having a water purification function for removing residual chlorine is attached to a hose-shaped water outlet of a bathroom or a washstand.

FIG. 2 is a cross-sectional view showing an example of this conventional representative shower head with a water purification function. The conventional shower head 20 with a water purification function has a shower nozzle having a large number of water spray holes 21a on an end face, and the shower nozzle 21 is screw-fitted at one end via a packing 24, and the other end is a hose-shaped water outlet. The shower head main body 23 is constituted by a long cylindrical grip portion 22 which is connected to the inside and has a water passage 22a. Further, the shower nozzle 2 in the shower head body 23
Inside 1, a water purification cartridge 25 in which an appropriate amount of a water treatment agent 25b such as calcium sulfite is filled according to the specification performance is exchangeably housed inside a casing 25a.

The shower nozzle 21 has a cylindrical main body 21.
b is screwed into the long cylindrical grip portion 22, and a spoke portion 21 c is formed integrally with the cylindrical main body 21 b on the other end surface, and the spoke portion 21 c
Is a screw 2d with a large number of water holes 21a.
1e.

Raw water is introduced into the shower head 20 from one end of the long cylindrical grip portion 22, and the raw water that has passed through the water passage 22 a is supplied to the water purification cartridge 25.
The water passes through the inside and is purified by a water treatment agent to be purified water, and is discharged in a shower form from the water spray holes 21 a of the shower nozzle 21.

In the conventional shower head 20 having the water purification function, the shower nozzle 21 of the shower head body 23 and the grip portion 22 are integrally connected by screw fitting as described above. When the life of the water treatment agent is over, the screw fitting between the shower nozzle 21 and the grip 22 is released and the water purification cartridge 25 is replaced with a new one, so that the water purification function can be continued. I have.

[0007]

In the above-described conventional shower head 20 with a water purification function, the cylindrical grip portion 22 that forms the major part of the shower head 20 is long, so that it can be used in a narrow place such as a wash basin. Difficult to install. Even if the shower head 20 can be installed on a wash basin, the shower head 20 interferes with ordinary use such as hand washing and tooth brushing, which is inconvenient.

Further, since the cylindrical grip portion 22 is long, the grip portion 22 naturally requires a large amount of manufacturing material, so that the manufacturing cost is high, and the large amount of such a large amount of material is required. There is also a problem that the weight of the shower head 20 becomes heavy depending on the material. Further, the length of the water passage 22a inside the grip portion 22 is increased, so that a pressure loss occurs in the water passage 22a, the flow rate of purified water is reduced, and a sufficient shower water discharge force is not obtained, and the usability is reduced. It was not preferable from the point of view.

Further, the shower nozzle 21 has a cylindrical main body 21b and a watering plate 21d having a plurality of watering holes 21a.
Are separate bodies, and both are fixed by screws 21e. By forming the shower nozzle 21 in a two-member structure as described above, the manufacturing cost of the member increases, and the screw 21e is formed.
However, the necessity of assembling parts such as these, and the increase in assembling work increase the cost. Further, in order to fix the water spray plate 21d to the cylindrical main body 21b, a spoke portion 21c must be formed on an end surface of the cylindrical main body 21b, and the shower nozzle 21 has a space for the spoke portion 21c. Therefore, there is a problem that the size of the shower nozzle 21 also becomes large.

When replacing the water purification cartridge 25, the water purification cartridge 25 is fitted into the shower nozzle 21 or the grip portion 22, and then the shower nozzle 21 and the grip portion 22 are screwed again. However, when the water purification cartridge 25 is not fitted in a predetermined posture at this time, the screw fitting between the shower nozzle 21 and the grip portion 22 cannot be performed smoothly, and the screw fitting operation is not performed. It was complicated and time-consuming.

Further, the shower head 2 with the water purification function is provided.
0 indicates that if the usage period is prolonged, foreign matter such as water scale accumulates in the water spray holes 21a of the shower nozzle 21 and causes a problem such as a lateral jump of water or a decrease in the amount of discharged water. Need to be cleaned regularly. Also, if the inside of the main body is used without being periodically cleaned, germs will grow inside the shower nozzle 21 to which the purified water from which residual chlorine has been removed will adhere, and the shower head 20 will be used to purify the water containing the germs. Is discharged, which is not hygienic. However, since the water sprinkling holes 21a are very small and there are many, the cleaning work is complicated and time-consuming, and frequent cleaning at home becomes a heavy burden.

The present invention has been made in view of the problems of such a conventional shower head having a water purification function. That is, the present invention is compact and can be easily installed even in a narrow space, is convenient for daily use, has low manufacturing costs, is excellent in convenience and economy, and has a water treatment filled inside. The work of replacing the agent with a new one can be performed easily and in a short time, and there is no need to periodically clean the sprinkling holes of purified water. It is an object of the present invention to provide a shower head with a water purification function and a shower nozzle capable of always discharging purified water having a high degree of cleanliness without the possibility of discharge of purified water mixed with various germs. .

[0013]

In order to achieve the above object, the present invention relates to a shower nozzle having a large number of water spray holes on an end face, and a water treatment agent filled and integrated in a main body thereof. , A water passage is formed therethrough, and the shower nozzle is detachably attached to one end,
And a short-length hose connecting member having the other end connected to the hose.

[0014] The shower head with a water purification function of the present invention comprises:
By making the hose connecting member that connects the shower nozzle and the hose-shaped water outlet into a short tubular shape, the shower head can be made compact and can be easily used even in a narrow place such as a wash basin. Can be installed.
In addition, at the time of hand washing and tooth brushing, hair washing in narrow washstand,
The shower head does not get in the way and is excellent in usability. In addition, since the hose connecting member is short, the material for the hose connecting member can be significantly reduced, so that the shower head can be manufactured at low cost. Further, since the weight of the shower head can be reduced, the user's fatigue can be reduced even when the shower head is used for a long time in a beauty salon or the like. In addition, since the water passage in the shower head, particularly in the hose connecting member, becomes short, the pressure loss in the water passage is small, and a sufficient shower water discharging force can be obtained.

The shower head with a water purification function of the present invention comprises:
Since the inside of the shower nozzle is integrated with the water treatment agent, when the life of the water treatment agent is over, the shower nozzle may be removed from the hose connecting member and replaced with a new shower nozzle. That is, as compared with the conventional case in which the shower nozzle and the grip portion of the shower head body are removed and the water purification cartridge housed inside is replaced, and the shower water nozzle is attached to the grip portion again, the attachment and detachment of the water purification cartridge is performed. Since there is no work, the replacement work can be performed in a short time. In addition, the replacement operation can be performed smoothly without the inconvenience that the water purification cartridge is not fitted in a predetermined posture as in the related art and the shower nozzle cannot be attached to the grip portion.

In addition, since not only the water treatment agent but also the entirety of the shower nozzle is periodically replaced, complicated work such as cleaning the water sprinkling hole of the shower nozzle at home as in the related art is unnecessary, and the water sprinkling hole is not required. There are no problems such as sideways jumping of water due to clogging or poor water discharge. Moreover, by replacing the shower nozzle with which chlorine-free purified water easily contacts and easily propagates germs, it is possible to always supply clean purified water, which is excellent in terms of hygiene.

Further, it is preferable that the shower nozzle has a cylindrical main body and a watering plate having a large number of watering holes, and the watering plate is preferably formed integrally with one end surface of the cylindrical main body. In that case, members such as screws and spokes for attaching the sprinkler plate to the tubular main body are not required, and the assembling work is also unnecessary, so that the production efficiency is improved and the production cost is reduced. Can be done.

Further, it is preferable that a drip-proof rib is projected from an outer periphery of the water spray plate. By the drip-proof ribs, the water discharged in the form of a shower does not excessively scatter around, and dripping is prevented. If the dimension of the drip-proof rib protruding from the sprinkler plate is too long, it interferes with the water flow and disturbs the flow. Conversely, if it is short, the effect of preventing dripping is weakened. Therefore, it is preferable that the projecting dimension of the drip-proof rib is about 1 to 10 mm.

Further, the shower nozzle is preferably formed of a transparent or translucent material, and the hose connecting member is preferably formed of a transparent or translucent material. In this case, since the dirt or crushing of the water treatment agent that is integrated into the shower nozzle and the degree of weight reduction can be externally observed, it is easy to confirm the replacement time of the shower nozzle. it can.

It is preferable that a water gap is formed between the cylindrical body of the shower nozzle and the water treatment agent. When such a water gap is formed, a part of the raw water introduced from the hose connecting member or water passing through the water purification cartridge is positively applied to the water gap formed around the cartridge. And the pressure of water passing through the water treatment agent in the water purification cartridge can be reduced, so that the water treatment agent can be prevented from being crushed or deformed. Further, excessive contact between the raw water and the water treatment agent can be eliminated, and the life of the water treatment agent can be extended without waste.

The width of the water gap is 0.1 to 1 mm.
It is preferred that If it is less than 0.1 mm, the function as a flow channel cannot be secured, and the water pressure applied to the water treatment agent cannot be sufficiently reduced. On the other hand, if it is 1 mm or more, the amount of raw water passing through the water gap becomes excessive, and the water purification function is reduced.

The water treatment agent preferably contains at least one dechlorination agent of activated carbon, calcium sulfite and ascorbic acid. The water treatment agent may be used in the form of a powder, or in the form of a granule, tablet, column, or the like, and filled in the casing of the water purification cartridge. The casing may be filled with a treatment agent which is further wrapped in a non-woven fabric sheet and wound into a roll, or a mixture obtained by further mixing a granular water treatment agent with a synthetic fiber and molding. Further, as the water treatment agent, besides the dechlorination treatment agent, an agent for removing mold odor such as divinylbenzene polymer, a humectant such as collagen, and an aromatic oil such as herb-based plant extraction oil, depending on the purpose of use. Various agents such as an agent and a cooling agent such as menthol can be contained.

Further, the present invention is applied to any one of the shower heads described above, and has another main structure of a shower nozzle characterized in that a water treatment agent is filled and integrated in a main body thereof. . It should be noted that the shower nozzle is collected after use, the water treatment agent filled and integrated into the body after the end of its life is once removed, and the body and the sprinkling plate are washed and subjected to surface treatment.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings, with a representative example of a shower head having a water purification function. FIG. 1 is a longitudinal sectional view of the shower head 10 with the water purification function. The shower head 10 with a water purification function includes a shower nozzle 11 having a large number of water spray holes 11a on one end surface, and a short tubular hose connecting member 12.

The main materials of the shower nozzle 11 and the hose connecting member 12 are ABS resin, polypropylene resin, polysulfone resin, polyacetal resin, polycarbonate resin, polyphenylene ether resin and the like in consideration of pressure resistance, heat resistance, moldability and the like. It is preferable to employ the plastic of the above.

The shower nozzle 11 has a cylindrical main body 11.
b on one end surface of the main body 11b.
A sprinkling plate 11c having a is disposed. In this embodiment, the cylindrical main body 11b and the water sprinkling plate 11c are used.
Is integrally formed of the above-mentioned plastic. Thus, the sprinkling plate 11c is connected to the cylindrical body 1
By forming and integrating with 1b, there is no need to screw the sprinkler plate to the cylindrical body as in the conventional case, the number of parts can be reduced, and the conventional spoke fixing portion for the screw is not required. And the labor of assembling can be saved.

Further, in this embodiment, the sprinkling plate 1
A drip-proof rib 11e is provided on the outer circumference of 1c to protrude over the entire circumference. Therefore, the water discharged in the form of a shower does not excessively scatter around, and dripping is effectively prevented. The projecting dimensions of the drip-proof rib 11e are as follows:
The distance is set to 1 to 10 mm so as not to disturb the flow by interfering with the water flow and to effectively prevent dripping.

Further, inside the cylindrical main body 11b,
A water treatment agent 15, which is formed by forming calcium sulfite into a column having a diameter slightly smaller than the diameter of the main body 11b, is built in. Further, the other end of the cylindrical main body 11b is connected to a water passage plate 11d.
Is closed by That is, the shower nozzle 11
The water treatment agent 15 is filled and integrated into the main body 11b, and when the life of the water treatment agent 15 is over, the entire shower nozzle 11 can be replaced. In addition, by adopting a transparent or translucent material for the shower nozzle 11 and the hose connecting member 12, the water treatment agent 15 filled and integrated in the shower nozzle 11 can be stained or crushed, or the remaining amount can be reduced. Can be confirmed from.

Since the water treatment agent 15 is formed into a column having a diameter slightly smaller than the diameter of the main body 11b of the shower nozzle 11, as described above, the water treatment agent 15 and the main body 11b are formed. A water gap 17 is formed between the two.

A part of the raw water introduced from the hose connecting member 12 and the water treatment
By positively letting the water that has passed through the water treatment agent 15 around the water treatment agent 15, the pressure of the water that passes through the water treatment agent 15 can be reduced, and the water treatment agent 15 is crushed or deformed. Can be prevented. The raw water is a water treatment agent 15
Excessive contact with the water treatment agent 15 can be prevented, the waste of the water treatment agent 15 can be eliminated, and the life of the water treatment agent 15 can be extended. The water gap 17 in the shower nozzle 11
Is preferably 0.1 to 1 mm. 0.1m
If it is less than m, the function as a flow path cannot be secured, and the pressure of water passing through the water treatment agent 16 cannot be sufficiently reduced. On the other hand, if it is 1 mm or more, the amount of untreated raw water passing through the water gap 17 becomes excessive, and the water purification function is undesirably reduced.

Further, a thread groove 11e is formed at an end of the cylindrical main body 11b which is closed by the water passage plate 11d. On the other hand, a thread groove 12b is also formed at one end of the hose connection member 12, and the shower nozzle 11 and the hose connection member 12 are detachably screw-fitted through a water seal packing 14. In this embodiment, the shower nozzle 11 and the hose connecting member 12 are used.
Are connected and integrated by screw fitting, but may be connected and integrated by a bayonet method.

The hose connecting member 12 has a short tubular shape and constitutes a water passage 12a inside. The shower nozzle 11 is attached to one end as described above, and the other end has a hose adapter fitting portion 12c. Then, it is connected to a hose-shaped water outlet through a water seal packing 16. In this embodiment, the hose adapter fitting portion 12c employs a screw system. The water seals 14 and 16 are members for sealing water leakage between the members, and a commercially available O-ring made of a material such as silicon or NBR can be used.

As described above, the present invention is characterized in that the hose connecting member 12 for connecting the shower nozzle 11 and the hose-shaped water outlet has a short tubular shape. In other words, by using the hose connecting member 12 having a short tubular shape instead of the grip portion 22 having a long tubular shape as in the conventional shower head 20 shown in FIG. The head 10 becomes compact and can be easily installed in a narrow place such as a wash basin. In addition, hand washing and tooth brushing in a narrow wash basin,
The shower head 10 does not get in the way when washing the hair, and is easy to use. In addition, the hose connection member 12 having the short tubular shape is used.
Therefore, the material used for the showerhead 10 can be reduced, the manufacturing cost can be reduced, and the weight of the showerhead 10 can be reduced. Further, since the water passage 12a of the hose connecting member 12 is also shortened, the water passage 1
The pressure loss at 2a is small, and a sufficient shower water discharging force can be obtained.

The raw water introduced from the lower end of the hose connecting member 12 and passed through the water passage 12 a in the connecting portion 12 is supplied from the water passage plate 11 d fixed to the one end of the shower nozzle 11 through the shower nozzle 11. Introduced into. In the shower nozzle 11, most of the raw water passes through the water treatment agent 15 and is purified by the water treatment agent to become purified water. In this embodiment, a part of the raw water passes through the water gap 17 as described above. I do. The purified water that has passed through the water treatment agent 15 and the raw water that has passed through the water passage gap 12 are joined together immediately before the water spray plate 11c formed and integrated with the cylindrical main body 11b of the shower nozzle 11, and are sprayed together. The water is discharged in a shower form from the water spray holes 11a formed in the plate 11c.

In the shower head 10 with a water purification function, when the life of the water treatment agent 15 is over, the shower nozzle 11 is manually turned to remove it from the hose connecting member 12 and a new shower nozzle 11 is newly inserted. The exchange work is completed only by screw-fitting the hose connection member 12, and the work can be performed in a very short time. In addition, since the shower nozzle 11 is integrated with the water treatment agent 15, the shower nozzle 21 is removed from the grip portion 22 as in a conventional shower head 20 shown in FIG. This eliminates the need for work, and furthermore, the separate water purification cartridge 25 is not fitted in a predetermined posture, so that the shower nozzle 21 and the grip portion 22 are not fitted.
There is no inconvenience such that the screw cannot be fitted with the screw, and the replacement operation is performed smoothly.

Further, since not only the water treatment agent 15 but also the entire shower nozzle 11 can be periodically replaced, the spray plate 11c in the shower nozzle 11 can be replaced without performing a complicated and time-consuming cleaning operation of the spray hole 11a. Watering hole 11
No foreign matter accumulates on a, and no problems such as lateral jumping of water or poor outflow of water do not occur. Also, since the shower nozzle 11 in which purified water from which residual chlorine is removed comes into contact with the inside is periodically replaced, the shower nozzle 11 is not used for a long period of time, so that germs do not grow and clean water is always supplied. Yes, it is hygienic.

The used shower nozzle 11
The water treatment agent 15 which has been recovered and has been filled into the main body after the end of its life is once removed, the main body 11b and the sprinkling plate 11c are washed and subjected to surface treatment, and then a new water treatment agent 15 is filled and integrated. It can also be played back.

In this embodiment, the water treatment agent 15 is formed by molding calcium sulfite into a cylindrical shape.
As the water treatment agent 15, other activated dechlorination agents such as granular activated carbon, fibrous activated carbon, and ascorbic acid can be used alone or as a mixture of several types. Also, the water treatment agent 15 may be filled in the form of powder, granules, tablets, etc., and then filled into the shower nozzle 11, or a powdered material may be further formed of a nonwoven sheet. It is also possible to use a material wrapped in a wrapping roll, or a material obtained by mixing a granular material with a synthetic fiber and molding.

In addition to the dechlorinating agent as the water treatment agent 15, depending on the purpose of use, agents for removing mold odor such as divinylbenzene-based polymers, humectants such as collagen, herbal plant-derived oils, etc. Various agents such as a fragrance and a refreshing agent such as menthol can be contained.
