Abstract
Description
Shower head external air intake blocking device
[0001] This specification relates to a shower head, and more specifically, to a device for blocking the inflow of outside air into 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 spray plate.
[0002] 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 intended to be admitted as prior art.
[0003] In general, a shower head is equipped with a flat spray plate with a number of small spray holes of the same size perforated at its tip, and performs a shower function by distributing and discharging water supplied through a shower hose through 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 account for a large proportion.
[0004] Conventional shower devices are being developed to have various functions such as removing residual chlorine in water, filtering foreign substances, ionizing, antibacterial, deodorizing, etc., and performing various water treatment functions such as massage functions, and the demand of users who want to shower with cleaner water is increasing.
[0005] That is, a functional shower head is being used that purifies the supplied raw water by installing a water softener, residual chlorine remover, filter, etc. in the shower head, or sprays functional water with vitamins, aroma oils, or fragrances added to the purified water.
[0006] 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.
[0007] To reduce the risk of exposure to such pathogens, disposable showerhead filters are attached to showerheads to prevent showerers from being exposed to various contaminants such as waterborne pathogens such as fungal spores, bacteria, and protozoa.
[0008] 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 spray plate and becoming contaminated by bacterial growth.
[0009] 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.

[0048] Hereinafter, with reference to the attached drawings, an external air intake blocking device of a shower head according to a preferred embodiment of the present specification will be described in detail.
[0049] 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
[0050] A typical body part (11) having a passage (10) formed therein through which water (e.g., tap water) moves;
[0051] A conventional lid (12) that is detachably screwed onto the outlet of the body (11);
[0052] A conventional water spray plate (14) that is mounted on the catch (12a) of the lid (12) and discharges water moving to the lid (12) through a hole (13);
[0053] It is characterized by having a circular external air inlet blocking port (16) in which an arbitrary-shaped cutout (15) (for example, a sheath shape rather than a hole) is repeatedly formed in the circumferential direction so as to be opened by the water pressure of water that passes through the body part (11) and moves toward the water spray plate (14), and allows water to pass toward the water spray plate (14), and when the water is cut off from the body part (11), it is restored to the initial state by elastic force to block the movement of water toward the water spray plate (14), and prevents external air from flowing into the body part (11) through the perforation (13).
[0054] According to a more preferred embodiment, as shown in FIGS. 4 to 8, the above-described external air inlet blocking opening (16)
[0055] It is characterized by including a guider (17) which is formed protrudingly on a surface opposite to 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).
[0056] As shown in FIG. 4 and FIG. 6, the aforementioned guider (17)
[0057] It is characterized by being repeatedly formed in a concentric ring shape on one side of the external air inlet blocking port (16).
[0058] The aforementioned guide (17)
[0059] It is characterized by the fact that semicircular protrusions (not shown) are repeatedly formed on one side of the external air intake block (16) in a concentric circle but spaced at equal intervals in the circumferential direction.
[0060] As shown in FIG. 4 and FIG. 6, the aforementioned cut portion (15)
[0061] It is characterized by being repeatedly formed by maintaining equal spacing between adjacent guiders (17) and guiders (17) in a circular direction.
[0062] As shown in Fig. 4, the aforementioned incision (15)
[0063] The direction of water flow passing through the external air inlet blocking port (16) can be formed in a straight, S-shaped, ∪-shaped, or ∩-shaped shape, and these are only illustrated and described in the drawing to help understanding, and are not meant to be limited to these.
[0064] The aforementioned external air inlet blocking port (16) can be formed of any one of a conventional silicone material, synthetic resin material, and rubber material, and is not meant to be limited to these.
[0065] 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 to extend along the edge of the 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).
[0066] As shown in FIG. 6 and FIG. 7, a cutout (15) is formed in the center to protrude a control portion (19) that controls whether water passes through the water spout (14), and a groove (20) that allows water inside the lid (12) to smoothly flow into the cutout (15) of the control portion (19) is formed on the inner surface of the external air inflow blocking port (16) outside the cutout (15). (That is, the cutout (15) and the groove (20) are formed on the same center line.)
[0067] 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;
[0068] A second case (24) in the form of a cartridge in which a second hook (23) for assembly is formed on the contact surface to correspond to the first hook (21); is provided;
[0069] 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 pressure 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).
[0070] 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;
[0071] A plurality of protruding protrusions (12b) (for example, three protrusions are formed) that protrude toward the spray plate (14) on the catch (12a) of the lid (12) and are coupled to the fixing groove (14a);
[0072] A through hole (18a) formed through the leak prevention hole (18) of the external air inlet blocking hole (16); is provided.
[0073] After the centers of the fixing groove (14a) of the spray plate (14) and the through hole (18a) of the external air intake blocking port (16) are aligned with each other and the protruding jaw (12b) of the lid (12) is fixed, a connecting piece (11a) extended from 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 spray 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).
[0074] As shown in FIG. 6 and FIG. 7, the aforementioned control unit (19)
[0075] It is characterized in that the external air inlet blocking port (16) is elastically deformed by the pressure of water passing through the cut portion (15) of the external air inlet blocking port (16) so that the control portion (19) does not come into contact with the sprinkler plate (14) and is formed to protrude at a lower height than the guider (17).
[0076] Hereinafter, an external air intake blocking device of a shower head according to one embodiment of the present specification is described according to the attached drawings.
[0077] As shown in FIGS. 1 to 9, the fixing groove (14a) formed on the protruding jaw (12b) formed on the catch jaw (12a) of the aforementioned lid (12) is formed at equal intervals in the circumferential direction on the outer surface of the spray plate (14) and is cut open to allow the outside to be opened, and the centers of the through-hole (18a) formed in the leak-prevention port (18) of the external air inlet blocking port (16) are aligned with each other to secure it in place. When the connecting piece (11a) extended from the end of the body portion (11) is screwed onto the lid (12), the protruding jaw (12b) of the lid (12) can be fixed to the fixing groove (14a) of the spray plate (14) and the through-hole (18a) of the leak-prevention port (18) of the external air inlet blocking port (16) without moving due to the pressure of the connecting piece (11a).
[0078] When the shower head described above is used, the plurality of cutouts (15) formed in the outside air inlet 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 cutouts (15) are restored to their 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 body part (11) through the perforations (13) of the spray plate (14).
[0079] To explain this in detail, as shown in FIGS. 4 and 6, when the water pressure is not generated inside the body part (11) by turning off the water faucet (for example, a tap, a lever, etc.) of the aforementioned shower head, 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.
[0080] 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), thereby preventing it from moving toward the spray plate (14). At the same time, outside air can be prevented from passing through the perforation (13) of the spray plate (14) and flowing into the inside of the body part (11) by the outside air inlet blocking port (16).
[0081] Meanwhile, as shown in FIGS. 5 and 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 gaped state) by the water pressure generated inside the body portion (11).
[0082] 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 of the body part (11) passes through the opened cut part (15) and then moves toward the spray plate (14) and is discharged through the perforation (13).
[0083] As described above, when the external air intake blocking port (16) is pressurized by the pressure of the water passing through the body part (11) and the cut portion (15) is opened to allow water to pass, a space (i.e., a space equivalent to the height at which the guider (17) protrudes from the external air intake blocking port (16)) can be secured between the water spray plate (14) and the external air intake blocking port (16) by the guider (17) formed on the outer surface of the external air intake blocking port (16) facing the water spray plate (14).
[0084] Accordingly, when the cut portion (15) of the external air intake block (16) is pressurized by the water pressure passing through the body portion (11) to open it, the space secured by the guider (17) between the spray plate (14) and the external air intake block (16) prevents the external air intake block (16) (which may be formed of a silicone material, for example) from being elastically deformed and coming into contact with the spray plate (14). As a result, the water inside the body portion (11) can smoothly pass through the cut portion (15) of the external air intake block (16) and the perforation (13) of the spray plate (14) in sequence to be discharged outside the shower head.
[0085] As shown in Fig. 7, the control part (19) with the cut-out (15) formed in the aforementioned external air inlet blocking port (16) is formed to protrude toward the spray plate (14) and the groove (20) is formed outside the cut-out (15) (the cut-out (15) and the groove (20) are formed on the same center line), so that the water inside the lid (12) passes through the groove (20) and moves smoothly toward the cut-out (15). Accordingly, it is possible to prevent water moving from the body part (11) toward the spray plate (14) from stagnating due to interference by the external air inlet blocking port (16).
[0086] 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 guider (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).
[0087] 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 unit (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).
[0088] 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).
[0089] 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.
[0090] Although the above-described specification has been described with reference to exemplary preferred technical ideas, those skilled in the art to which the specification pertains will be able to make various modifications and equivalent other embodiments without departing from the essential characteristics of the specification.
[0091] 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 the equivalent scope should be interpreted as being included in the scope of rights of this specification.
[0092] This relates to a shower head that sprays water filled in the shower head through the perforations of the spray plate.
