Description

Shower head outside air intake blocking device

The present specification relates to a shower head, and more specifically, to an outside air intake blocking device for a shower head to prevent water filled in the shower head from being contaminated by being exposed to outside air through a hole in a sprinkler plate.

Unless otherwise indicated herein, the materials described in this section are not prior art to the claims of this application and their inclusion in this section is not an admission that they are prior art.

In general, a shower head is equipped with a flat spray plate with a number of small spray holes of the same size perforated on its tip, and performs a shower function by dispersing water supplied through a shower hose into the spray holes of the spray plate. In order to perform a more effective shower function, the number, area, and distribution of the spray holes are of great importance.

Conventional shower devices are being developed to have various functions, such as removing residual chlorine in water, filtering foreign substances, ionization, antibacterial, deodorizing, etc., and performing various water treatment functions, such as performing massage functions. There is an increasing demand from users who want to shower with cleaner water.

That is, a functional shower head is being used that purifies the supplied raw water by installing a water softener, residual chlorine remover, or filter in the shower head, or sprays functional water with vitamins, aroma oils, or fragrance added to the purified water.

Meanwhile, contamination of water discharged from showers or faucets to people who may be susceptible to infection is undesirable, and exposure to contaminants such as pathogens can lead to debilitating, costly infections, and even death.

To reduce the risk of exposure to such pathogens, disposable showerhead filter devices are attached to showerheads to prevent showerers from being exposed to various contaminants such as waterborne pathogens such as fungal spores, bacteria, and protozoa.

An embodiment of the present specification relates to an outside air intake blocking device for a shower head, which prevents water filled in the shower head from being exposed to outside air through a perforation of a sprinkler plate and becoming contaminated with bacterial growth.

An embodiment of the present specification relates to an external air intake blocking device for a shower head, which can prevent skin troubles in atopic patients, chronic skin disease patients, or users with sensitive skin from occurring due to bacteria growing inside the shower head.

Hereinafter, an external air intake blocking device of a shower head according to a preferred embodiment of the present specification will be described in detail with reference to the attached drawings.

Referring to FIGS. 1 to 9, an external air intake blocking device of a shower head according to one embodiment of the present specification is

A conventional body part (11) having a passage (10) formed therein through which water (e.g., tap water) moves;

A conventional lid (12) that is detachably screwed onto the discharge port of the body (11);

A conventional sprinkler plate (14) that is installed on the catch (12a) of the lid (12) and discharges water moving to the lid (12) through a hole (13);

It is characterized by having a circular external air inlet blocking port (16) in which an arbitrary-shaped cut portion (15) (for example, a sheath shape rather than a hole) is repeatedly formed in a circumferential direction, which is formed inside a sprinkler plate (14), is converted into an open state by the water pressure of water passing through the body part (11) and moving toward the sprinkler plate (14), allows water to pass toward the sprinkler plate (14), and, when the water is cut off from the body part (11), is restored to the initial state by elastic force to block the water from moving toward the sprinkler plate (14), and blocks external air from flowing into the body part (11) through the perforation (13).

According to a more preferred embodiment, as shown in FIGS. 4 to 8, the above-described external air inlet blocking port (16)

It is characterized by including a guide (17) that is formed by protruding on a surface facing the sprinkler plate (14) and, when the external air inlet blocking port (16) is pressurized by the water pressure of water passing through the body part (11), secures a space between the external air inlet blocking port (16) and the sprinkler plate (14) to smoothly guide the water flow toward the sprinkler plate (14).

As shown in Figures 4 and 6, the aforementioned guider (17)

It is characterized by being repeatedly formed in a concentric ring shape on one side of the outside air intake blocking port (16).

The aforementioned guide (17)

It is characterized by the fact that semicircular protrusions (not shown) are repeatedly formed on one side of the outside air intake blocking port (16) in a concentric circle but spaced at equal intervals in the circumferential direction.

As shown in Figures 4 and 6, the aforementioned incision (15)

It is characterized by being repeatedly formed by maintaining equal intervals in the direction of circumference between neighboring guides (17) and guides (17).

As shown in Fig. 4, the aforementioned incision (15)

The direction of water flow passing through the outside air inlet blocking port (16) can be formed in a straight line, an S-shape, a ∪-shape, or a ∩-shape, and these are only illustrated and described in the drawing to help understanding, and are not meant to be limited to these.

The above-mentioned external air inlet blocking port (16) can be formed of any one of a conventional silicone material, a synthetic resin material, and a rubber material, and is not meant to be limited to these.

As shown in Fig. 9, it is characterized by including a leak prevention device (18) (i.e., acting as an O-ring) that is formed by extending to the edge of an external air intake blocking port (16) and prevents water from leaking through the gap between the lid (12) and the external air intake blocking port (16) due to elastic deformation caused by the pressure of the connecting piece (11a) of the body part (11) when the lid (12) is screwed onto the body part (11).

As shown in FIG. 6 and FIG. 7, a cut portion (15) is formed in the center to protrude a control portion (19) for controlling whether water passes through it toward the sprinkler plate (14), and a groove (20) for allowing water inside the lid (12) to flow smoothly into the cut portion (15) of the control portion (19) is formed on the inner surface of the external air intake blocking port (16) outside the cut portion (15). (That is, the cut portion (15) and the groove (20) are formed on the same center line.)

As shown in Fig. 8, a first case (22) in the form of a cartridge that accommodates the edge of the aforementioned sprinkler plate (14) and the leak-prevention port (18) of the external air inlet blocking port (16), and has a conventional first hook (21) for assembly formed on the contact surface;

A cartridge-shaped second case (24) is provided, in which a second hook (23) for assembly is formed on the contact surface to correspond to the first hook (21).

When the first and second hooks (21, 23) are connected in a protruding manner while the sprinkler plate (14) and the external air inlet blocking port (16) are accommodated in the first case (22), the leak prevention port (18) is elastically deformed by pressure by the pressurizing ring (25) formed in a ring shape on the inner surface of the second case (24), thereby sealing the gap between the leak prevention port (18) and the inner surfaces of the first and second cases (22, 24).

As shown in FIG. 2, FIG. 3, and FIG. 9, a fixed groove (14a) (for example, three grooves are formed) is formed at equal intervals in the circumferential direction on the outer periphery of the aforementioned sprinkler plate (14) and is cut so that the outer side is open;

A plurality of protruding projections (12b) (for example, three projections are formed) that protrude toward the sprinkler plate (14) on the catch (12a) of the lid (12) and are coupled to the fixing groove (14a);

A through hole (18a) formed through the leak prevention hole (18) of the external air inlet blocking hole (16) is provided;

After the centers of the fixing groove (14a) of the sprinkler plate (14) and the through hole (18a) of the external air intake blocking port (16) are aligned with each other and the lid (12) is secured, a connecting piece (11a) that is extended to the end of the body part (11) is screwed onto the lid (12), so that the protruding jaw (12b) of the lid (12) is fixed to the fixing groove (14a) of the sprinkler plate (14) and the through hole (18a) of the external air intake blocking port (16) without moving by the pressure of the connecting piece (11a).

As shown in Figures 6 and 7, the aforementioned control unit (19)

It is characterized in that the external air intake blocking port (16) is elastically deformed by the pressure of water passing through the cut portion (15) of the external air intake blocking port (16) so that the control portion (19) does not come into contact with the sprinkler plate (14) and protrudes at a lower height than the guide (17).

Hereinafter, an external air intake blocking device of a shower head according to one embodiment of the present specification is described with reference to the attached drawings.

As shown in FIGS. 1 to 9, the fixing groove (14a) formed on the protrusion (12b) formed on the catch (12a) of the lid (12) described above is formed at equal intervals in the circumferential direction on the outer surface of the sprinkler plate (14) and is cut so that the outside is open, and the centers of the through-hole (18a) formed in the leak-prevention port (18) of the external air intake blocking port (16) are aligned with each other to secure it in place. When the connecting piece (11a) extended to the end of the body portion (11) is screw-connected to the lid (12), the protrusion (12b) of the lid (12) can be fixed to the fixing groove (14a) of the sprinkler plate (14) and the through-hole (18a) of the leak-prevention port (18) of the external air intake blocking port (16) without moving due to the pressure of the connecting piece (11a).

When the shower head described above is used, the plurality of cut portions (15) formed in the outside air intake blocking port (16) are converted to an open state (opened) by water pressure, thereby allowing water moving from the body part (11) to pass through and be discharged toward the spray plate (14). On the other hand, when the shower head is not used (meaning a state in which no water pressure is generated inside the body part (11)), the cut portions (15) are restored to the initial state by elastic force, thereby blocking water in the body part (11) from moving toward the spray plate (14), and also blocking outside air from flowing into the inside of the body part (11) through the perforations (13) of the spray plate (14).

To explain this in detail, as shown in FIGS. 4 and 6, when the water supply (e.g., a faucet, a lever, etc.) of the aforementioned shower head is turned off and water pressure is not generated inside the body part (11), the cut part (15) formed concentrically in the circumferential direction to the external air intake blocking port (16) coupled to the discharge port of the lid (12) maintains the initial state of being in close contact.

Due to this, water inside the body part (11) is prevented from passing through the cut portion (15) of the outside air inlet blocking port (16) and moving toward the sprinkler plate (14). At the same time, outside air can be prevented from passing through the perforation (13) of the sprinkler plate (14) and flowing into the inside of the body part (11) by the outside air inlet blocking port (16).

Meanwhile, as shown in FIG. 5 and FIG. 7, when the faucet is turned on to use the aforementioned shower head, the cut portion (15) of the external air intake blocking port (16) can be turned to an open state (i.e., a gapped state) by the water pressure generated inside the body portion (11).

That is, as the pressure of the water moving from the body part (11) opens the cut part (15) of the external air inlet blocking port (16), the water in the body part (11) passes through the opened cut part (15) and then moves toward the sprinkler plate (14) and is discharged through the perforation (13).

As described above, when the pressure of the water passing through the body (11) pressurizes the external air intake blocking port (16) and the cut portion (15) is opened to allow water to pass through, a space (i.e., a space equivalent to the height at which the guide (17) protrudes from the external air intake blocking port (16)) can be secured between the water sprinkler plate (14) and the external air intake blocking port (16) by the guide (17) formed on the outer surface of the external air intake blocking port (16) facing the water sprinkler plate (14).

Accordingly, when the cut portion (15) of the external air intake blocking port (16) is pressurized and converted to an open state by the water pressure of the water passing through the body portion (11), the external air intake blocking port (16) (which may be formed of a silicone material, for example) is prevented from being elastically deformed and coming into contact with the spray plate (14) due to the space secured by the guide (17) between the spray plate (14) and the external air intake blocking port (16). As a result, the water inside the body portion (11) can smoothly pass through the cut portion (15) of the external air intake blocking port (16) and the perforation (13) of the spray plate (14) in sequence and be discharged outside the shower head.

As shown in Fig. 7, the cut portion (15) formed in the aforementioned external air inlet blocking port (16) protrudes toward the spray plate (14) in the control portion (19) located at the center, and a groove (20) is formed outside the cut portion (15) (the cut portion (15) and the groove (20) are formed on the same center line), so that water inside the lid (12) passes through the groove (20) and moves smoothly toward the cut portion (15). Accordingly, it is possible to prevent water moving from the body portion (11) toward the spray plate (14) from stagnating due to interference by the external air inlet blocking port (16).

At this time, it is preferable that the control part (19) protruding toward the spray plate (14) in the aforementioned external air inlet blocking port (16) be formed at a lower height than the guide (17) so that the external air inlet blocking port (16) is elastically deformed by the pressure of water passing through the cut portion (15) and the control part (19) does not come into contact with the spray plate (14).

That is, when the external air inlet blocking port (16) is elastically deformed by the water pressure passing through the cut portion (15) and the control portion (19) is pressed against the spray plate (14), no space is secured between the spray plate (14) and the external air inlet blocking port (16), thereby interfering with the water flow toward the perforation (13) of the spray plate (14).

As shown in Fig. 8, the first case (22) in the form of a cartridge having a first hook (21) formed on the contact surface and accommodating the edge of the aforementioned sprinkler plate (14) and the leak-prevention port (18) of the external air inlet blocking port (16), and the second case (24) in the form of a cartridge having a second hook (23) formed on the contact surface are provided, so that when the first and second hooks (21, 23) are unevenly joined while the sprinkler plate (14) and the leak-prevention port (18) of the external air inlet blocking port (16) are accommodated in the first case (22), the leak-prevention port (18) is elastically deformed by the ring-shaped pressure ring (25) formed on the inner surface of the second case (24) so as to seal the gap between the leak-prevention port (18) and the inner surfaces of the first and second cases (22, 24).

That is, if the aforementioned sprinkler plate (14), external air inlet blocking port (16), and first and second cases (22, 24) are commercialized as a set (modularized), consumers can purchase them and easily combine them with a shower head to use them conveniently.

Although the above-described specification has been described with reference to exemplary embodiments of the present invention, it will be apparent to those skilled in the art that various modifications and equivalent other embodiments may be made without departing from the essential characteristics of the specification.

Therefore, the embodiments disclosed in this specification are not intended to limit the technical idea but to explain it, and the protection scope of the specification should be interpreted by the technical idea of the claims, and all technical ideas within a scope equivalent thereto should be interpreted as being included in the scope of rights of this specification.

This relates to a shower head that sprays water filled in the shower head through the perforations of the sprinkler plate.
