Description

Technical Field

[0001] The present invention relates to a pumping tumbler for making beverages, and more particularly to a pumping tumbler for making beverages, which contains drinking water and additives at the same time, and can easily make beverages by sucking additives and adding them into drinking water according to the needs of users. The pumping tumbler is not only easy to use, but also can prevent the outflow of contents that may be generated during use, and the interior is easy to clean, thereby improving usability and hygiene. Background Art

[0002] Recently, with the development of the culture of carrying and drinking beverages and the change in environmental awareness caused by the controversy over the harmfulness of disposable cups, the number of users who use personal cups to carry and drink beverages is widely increasing.

[0003] Such a personal cup is generally composed of a cylindrical container body and a lid for opening and closing the upper end of the container body, so that beverages are stored in the container body and the beverages are drunk by opening the lid.

[0004] In addition, as the number of users of this cup increases, especially the number of people such as athletes, fitness trainers, and fitness enthusiasts who mix drinks such as milk in water for drinking is also increasing, and various products are being developed based on this.

[0005] In this regard, as an example of the technology related to the above-mentioned cup, Korean Patent Publication No. 10-2019-0066803 discloses a cup for infants with a retainer shell, including: a main body, which forms a space for containing liquid, including a container and a cap coupled to the container; an upper cover, which is rotatably coupled to the main body; and a retainer shell, which includes a protective cover inserted into the main body, and a retainer rope rotatably arranged on the protective cover, the two side ends of the retainer rope in the length direction are rotatably supported on the retainer shell, and the side of the cap is formed with a placement groove for inserting the retainer rope.

[0006] However, the lid structure of the conventional cup is a structure in which one side is rotated on the main body to open and close, and there is a problem that the lid is easily opened due to unexpected external force when carrying, so there are problems in usability and hygiene. Summary of the invention

[0007] Technical issues to be solved

[0008] The present invention is proposed to solve the existing problems as mentioned above. The purpose of the present invention is to provide a suction cup for making beverages, in which the structure of the lid is horizontally rotatable, easy to use, and can prevent the lid from opening due to unexpected external forces when carrying, thereby preventing hygienic problems caused by the leakage of contents.

[0009] In addition, an object of the present invention is to provide a suction cup for making beverages, which does not require the additives to be stored separately and taken out separately. Drinking water and liquid additives can be stored in the cup, thereby improving usability and hygiene. Additives can also be added in a quantitative manner through a built-in suction unit, thereby facilitating the preparation of beverages. The cup is constructed to be able to release the internal negative pressure that may be generated during suction, thereby allowing suction to proceed smoothly and stabilizing the outflow of additives.

[0010] Another object of the present invention is to provide a suction cup for beverage preparation, in which the interior of the suction part can be easily disassembled and easily cleaned, unlike the conventional suction part in which the flow path is difficult to clean, thereby improving hygiene.

[0011] Technical Solution

[0012] The present invention for achieving the above-mentioned purpose includes: a drinking water cylinder, the upper part of which is open and the lower end is shielded, and a drinking water storage space for storing drinking water or beverages is formed inside; a cover unit, which is detachably coupled to the upper part of the drinking water cylinder, shields the upper part of the drinking water cylinder with the upper part open, and forms a drinking opening for a user to drink the drinking water or beverage in the drinking water storage space; an additive cylinder, which is detachably coupled to the lower end of the drinking water cylinder, and an additive storage space for storing additives is formed inside; and a suction unit, which is arranged inside the drinking water cylinder and the cover unit, and sucks the additive in the additive cylinder through a flow path that passes through the bottom surface of the drinking water cylinder and supplies it toward the drinking water storage space.

[0013] At this time, the cover unit may include: a locking portion, which is detachably combined with the drinking water cylinder, with the drinking port formed through it on the upper side, and the suction unit is arranged through it at intervals toward the upper side and the drinking port; a rotating cover portion, which is rotatably combined with the upper part of the locking portion, rotates around a rotating axis extended toward the inner lower side, and has an opening portion, so that the locking portion is exposed, and the drinking port and the upper part of the suction unit are exposed through the opening portion when rotating; and a shielding support portion, which is located at the lower part of the locking portion, rotates by the rotation of the rotating cover portion, and moves along the rotating axis of the rotating cover portion, and opens and closes the drinking port when the rotating cover portion rotates.

[0014] In addition, according to the relative rotational position of the locking portion and the rotating cover portion, the usage status of the cover unit can be divided into: a storage mode, in which the drinking port and the suction unit are shielded to block the user's drinking water or beverage intake and the operation of the suction unit, and the drinking port is shielded by the shielding support portion; and a usage mode, in which the drinking port and the suction unit are opened through the opening portion, and the user can take in drinking water or beverages through the drinking port, or operate the suction unit.

[0015] In addition, the shielding support portion may include: a supporting body, which is rotatably inserted toward the inner side of a rotating shaft extending toward the inner and lower side of the rotating cover portion, and rises and falls in conjunction with the rotating shaft; a shielding portion, one end of which is combined with the outer side surface of the supporting body, and the other end is extended from the one end to open and close the drinking port; and an air shielding portion, which is protrudingly combined from the outer side surface of the supporting body and is extended to open and close the air hole formed in the locking portion through the rotation of the rotating shaft.

[0016] In addition, the supporting body can rise when the rotating cover rotates toward the storage mode, and the shielding part and the air shielding part shield the drinking port and the air hole; and descend when the rotating cover rotates toward the use mode, and the shielding part and the air shielding part open the drinking port and the air hole.

[0017] In addition, the shielding support portion may further include a balancing support portion protrudingly coupled from an outer side surface of the support body between the shielding portion and the air shielding portion to prevent the shielding portion and the air shielding portion from being eccentric with respect to the rotation axis.

[0018] In addition, the locking portion may be formed with a guide slit, and the upper side surface of the shielding support portion is embedded in the guide slit to guide the up and down movement of the shielding support portion, and one side of the shielding support portion is inserted into the cut groove to limit the rotation of the shielding support portion.

[0019] In addition, the cover unit may further include: an arc-shaped guide groove formed on the upper surface of the locking portion and corresponding to the rotation radius of the rotating cover portion; a stop protrusion for preventing rotation, which protrudes from the bottom of the rotating cover portion and is embedded in the guide groove to limit the rotation angle of the rotating cover portion.

[0020] In addition, when the rotating cover rotates toward the use mode direction, the contact surface of the stopper that contacts the side of the guide groove can be formed by an inclined surface. When the rotating cover applies a rotational force greater than a preset rotational force toward the use mode direction, the stopper disengages from the guide groove and rotates, and moves the support body downward.

[0021] In addition, when the rotating cover rotates toward the use mode direction, the contact surface of the guide groove that contacts the outer side surface of the stop member can be formed by an inclined surface. When the rotating cover applies a rotational force greater than a preset rotational force toward the use mode direction, the stop member disengages from the guide groove and rotates, moving the support body downward.

[0022] In addition, the shielding support portion may further include a lock cover, which is combined with the lower end portion of the rotating shaft to limit the descending position of the support body.

[0023] In addition, the suction unit may further include: a suction button portion, which is slidably and reciprocally disposed on the cover unit and moves as the user applies pressure; and a suction portion, which is located in the drinking water storage space of the drinking water cylinder and is raised and lowered by the reciprocating movement of the suction button portion, and is respectively connected to the drinking water storage space and the additive storage space, and sucks the additive into the drinking water storage space and causes it to flow out toward the drinking water storage space by being raised and lowered.

[0024] In addition, the suction of the additive can be formed by the following structure: a through hole, which connects and penetrates the lower end of the suction part and the central part of the bottom surface of the drinking water cylinder; and a suction pipe module, which is combined with the outer side surface of the bottom of the drinking water cylinder and extends toward the inside of the additive cylinder.

[0025] In addition, the suction button part may also include: a rod part, which is slidably arranged at the insertion port of the drinking water cylinder, with the upper part exposed to the outside of the drinking water cylinder, and the user pressurizes the upper end part, and the lower part transmits the external force to the suction part; and a guide sleeve, into which the rod part is inserted toward the inside to guide the reciprocating movement of the rod part.

[0026] In addition, the suction part may further include: a piston part, which is located in the drinking water storage space and is connected to the additive cartridge so as to suck the additive from the additive cartridge through the reciprocating movement of the suction button part; and a discharge pipe, which is in the shape of a hollow pipe and extends from the end of the piston part in a "U" shape to make the sucked additive flow out toward the drinking water storage space, and is linked to the suction button part and is raised and lowered by the reciprocating movement of the suction button part, thereby pressurizing the piston part.

[0027] In addition, the U-shaped curved surface of the discharge pipe may be provided with an openable and closable opening and closing plate, and the opening and closing plate is opened when the suction part is cleaned to facilitate cleaning of the piston part and the additive flow path of the discharge pipe.

[0028] In addition, the piston portion may include: a piston rod having a flow path formed therein, connected to and coupled with the discharge pipe, and raised and lowered by the reciprocating movement of the suction button portion; a piston housing having an inner space in which the piston rod is raised and lowered, a through hole connected to the interior of the additive cartridge being formed on a lower end surface, and the additive flowing into the inner space by the raising and lowering of the piston rod; and an elastic member coupled to the piston rod to provide a restoring force to the piston rod.

[0029] In addition, the piston rod may be detachably coupled to the piston housing, and the piston rod may be separated from the piston housing during cleaning.

[0030] In addition, the piston rod and the piston housing can be combined by inserting a fastening protrusion into a fastening groove, wherein the fastening protrusion protrudes from a side surface of a fastening ring that is liftably combined along the piston rod, and the fastening groove is formed in the piston housing.

[0031] In addition, the fastening groove may include: an upper cut portion, which is formed by cutting a size corresponding to the width of the fastening protrusion, so that the fastening protrusion can be inserted from the upper outside; a horizontal slit, which extends from the lower end of the upper cut portion toward the horizontal direction, so that the fastening protrusion inserted into the upper cut portion can move by rotation; and a vertical placement portion, which extends toward the upper side of the horizontal slit end, so that the fastening protrusion moving along the horizontal slit can be moved upward and placed by the elastic force of the elastic member, thereby limiting the rotational movement.

[0032] In addition, the suction pipe module may include: a coupling plate formed in a circular plate shape so as to be detachably coupled to the lower end of the drinking water cylinder; a circular plate-shaped expansion plate, which is detachably threadedly coupled to the lower center of the coupling plate; and a suction pipe, which is integrally formed on the expansion plate and extends from the expansion plate toward the bottom toward the additive cylinder, wherein the coupling plate, the expansion plate and the suction pipe may form an inflow path, which connects the coupling plate, the expansion plate and the suction pipe and moves the additive.

[0033] In addition, the suction pipe may be formed of a tapered circular pipe whose width gradually narrows downward.

[0034] In addition, it can also include: an elastic cover, which is combined with the outer side of the upper part of the combining plate and is formed of an elastic material so as to be closely attached to the lower end of the drinking water cylinder.

[0035] In addition, when the additive cartridge and the drinking water cartridge are threadedly coupled, the outer side of the elastic cover may be located between the upper end surface of the additive cartridge and the lower side of the outer side of the drinking water cartridge, and the outer side of the elastic cover is pressurized by the threaded coupling force of the additive cartridge and the drinking water cartridge, thereby sealing the inner space of the additive cartridge.

[0036] In addition, the lower surface of the expansion plate may be formed with a protruding curved surface protruding from the central portion, so that the adhesion force is increased at the central portion of the bonding surface when pressure is applied.

[0037] At this time, the upper portion of the inflow flow path of the suction pipe module may further include an opening and closing ball valve, which selectively opens and closes the inflow flow path as the piston rod rises and falls.

[0038] In addition, the additive cylinder can be open at the top and shielded at the bottom, forming the additive storage space toward the inside, and can be detachably combined with the lower part of the drinking water cylinder.

[0039] In addition, the additive cylinder may further include a shielding cover, which is formed of a circular plate made of elastic material to prevent the additive contained therein from flowing out, is pressed into the upper portion of the additive cylinder, and has a central through hole formed in the center thereof through which the suction pipe can pass.

[0040] In addition, the upper surface of the shield cover may be formed of a concave surface corresponding to the shape of the curved surface of the lower portion of the expansion plate.

[0041] Furthermore, the shielding cover may be provided with a grip portion on the upper surface thereof, which can be gripped when taking out the shielding cover.

[0042] In addition, an additive capsule composed of a disposable container for storing additives may be inserted into the additive cartridge. The additive capsule may include: a container portion contacting the inner side surface and the bottom surface of the additive cartridge; and a cover film covering the upper surface of the container portion.

[0043] Furthermore, the cover film may be perforated by pressurization of the suction tube.

[0044] In addition, the outer side surface of the container portion and the inner side surface of the additive cartridge may form locking shoulders and locking protrusions at positions corresponding to each other when combined, so that the additive capsule is located in the additive cartridge when the additive cartridge is separated from the drinking water cartridge.

[0045] In addition, the side wall of the container portion may include a protruding portion protruding outward on an upper portion of an outer peripheral surface thereof, and a step portion disposed on an inner side surface of the additive cylinder is formed at a boundary of the protruding portion.

[0046] In addition, a placement portion may be formed at the upper edge of the side wall, which is used to be placed on the upper edge of the additive cylinder.

[0047] In addition, the placement portion may include: a horizontal plate extending parallel to the outside from the upper end of the side wall by a distance corresponding to the thickness of the upper end edge of the additive cylinder; and a vertical plate extending downward by a predetermined distance from the end of the horizontal plate.

[0048] In addition, the additive cartridge may further include an additive cartridge cover portion, which is used to shield the upper portion of the additive cartridge when the additive cartridge is separated from the drinking water cartridge; the additive cartridge cover portion may be formed by a cap threadedly coupled to the additive cartridge, and a pressing protruding surface protruding downward in a hemispherical shape of a curved surface may be formed at the center of the inner side surface, for shielding the through hole in the upper portion of the additive capsule or the through hole of the shielding cover.

[0049] In addition, when the additive contained in the additive cylinder is extracted, in order to maintain the normal pressure in the additive cylinder, a normal-pressure flow path is formed for allowing external air to flow into the additive cylinder, wherein the normal-pressure flow path may include: a first normal-pressure flow path, which allows external air to flow into the lower space of the drinking water cylinder; a second normal-pressure flow path, which is connected to the first normal-pressure flow path, and allows the inflowing external air to flow into the interval space between the elastic cover and the connecting plate; and a third normal-pressure flow path, which is connected to the second normal-pressure flow path, and allows the inflowing external air to move toward the internal space of the additive cylinder below the connecting plate.

[0050] In addition, the first normal-pressure flow path can be formed as follows: in order to form a spacing space on the outside between the elastic cover and the lower end of the drinking water cylinder, a portion of the surface of either the upper portion of the elastic cover or the lower end of the drinking water cylinder can be formed by a step surface or an inclined surface; through an inflow hole formed in the side surface of the drinking water cylinder at the position of the spacing space between the elastic cover and the lower end of the drinking water cylinder, external air can flow into the spacing space between the elastic cover and the lower end of the drinking water cylinder through the inflow hole.

[0051] In addition, the first normal-pressure flow path can be formed as follows: in order to form a spacing space on the outside between the elastic cover and the lower end of the drinking water cylinder, a portion of the surface of either the upper portion of the elastic cover or the lower end of the drinking water cylinder can be formed by a step surface or an inclined surface; a spacing groove through which external air can move can be formed at a portion of the joint surface between the inner side surface of the lower portion of the drinking water cylinder and the outer side surface of the elastic cover, and the external air flowing in through the spacing space formed between the joint surface and the joint end of the drinking water cylinder and the additive cylinder passes through the spacing groove and flows into the spacing space on the outside between the elastic cover and the lower end of the drinking water cylinder.

[0052] In addition, the second normal pressure flow path can be formed by a vertical connecting hole, which is formed in the elastic cover and connects the interval space between the elastic cover and the lower end of the drinking water barrel, and the space between the lower part of the elastic cover and the connecting plate.

[0053] In addition, the first normal-pressure flow path can be formed as follows: the upper portion of the outer surface of the elastic cover is connected to the inner surface of the lower portion of the drinking water barrel, and the lower portion and the inner surface of the lower portion of the drinking water barrel are separated by a preset space; the outside air flowing in through the interval space formed between the joining surface and the joining end of the drinking water barrel and the additive barrel flows into the space between the lower portion of the outer surface of the elastic cover and the inner surface of the lower portion of the drinking water barrel.

[0054] In addition, the second normal pressure flow path can be formed by a horizontal connecting hole, which is formed on the side of the elastic cover, connecting the space between the lower part of the outer side surface of the elastic cover and the inner side surface of the lower part of the drinking water barrel, and the space between the lower part of the elastic cover of the elastic device and the combining plate.

[0055] In addition, the spacing space formed between the combined ends of the drinking water cartridge and the additive cartridge may be formed by an inflow cutout formed at the combined ends of the drinking water cartridge and the additive cartridge.

[0056] In addition, the spacing space formed between the combined ends of the drinking water cartridge and the additive cartridge may be formed by a step difference between the combined ends of the drinking water cartridge and the additive cartridge.

[0057] The engagement step difference can be formed by subtracting (-) the difference in length of the thread engagement height on the inner side of the lower part of the drinking water cylinder from the sum of the thread engagement height on the outer side of the upper part of the additive cylinder and the height of the outer side surface of the elastic cover.

[0058] At this time, the combination step difference can be 1-10 mm.

[0059] On the one hand, the spacing space formed between the joint surfaces of the drinking water cartridge and the additive cartridge can be formed by the gap spacing of the joint thread lines of the drinking water cartridge and the additive cartridge.

[0060] In addition, the third normal pressure flow path can be formed by an elastic button, which is provided on the combining plate and selectively opens and closes the interval space between the lower part of the elastic cover and the upper surface of the combining plate, as well as the internal space of the additive cylinder at the lower part of the combining plate, through elastic deformation due to air pressure difference.

[0061] In addition, the normal-pressure flow path may further include a fourth normal-pressure flow path that moves the air in the internal space of the additive cartridge toward the inside of the additive capsule.

[0062] In addition, the fourth normal-pressure flow path can be formed by the following structure: a flow path groove, which is formed from the outer end of the protruding curved surface of the expansion plate toward the center, forming a flow path so that air can move on the close-fitting surface of the expansion plate; and a cutting surface, which is formed by cutting the outer peripheral surface of the circular suction pipe, and is formed from the end of the flow path groove toward the bottom to a preset length, forming a space on the through surface of the suction pipe.

[0063] Beneficial Effects

[0064] The suction cup for beverage preparation according to the present invention provides the following effects.

[0065] First, when the opening and closing structure of the rotating cover is combined with the tube, the user rotates it horizontally, and when it is in use and storage, the shielding state can be adjusted accordingly, thereby preventing the rotating cover from being opened due to unexpected external force when carrying, and further preventing hygiene problems caused by the leakage of contents.

[0066] Second, an additive cartridge capable of storing and preserving liquid additives can be detachably coupled to a drinking water cartridge storing drinking water, thereby making it easy to store liquid additives, and it is unnecessary to separately store and take out the additives, and the additives can be quantitatively added to the cup, thereby making it easy to prepare beverages using the additives.

[0067] Third, unlike the prior art in which it is difficult to disassemble the suction unit and to clean the inside of the suction unit, the inside of the suction unit can be easily cleaned, so that the flow path for the additive to move can be cleaned, thereby improving sanitation.

[0068] Fourthly, since the components of the cover unit including the suction unit can be disassembled and assembled only through simple operations, it is easy to clean and maintain.

[0069] Fifth, a normal pressure flow path is formed, thereby preventing the function of the suction unit from being reduced due to negative pressure in the additive storage space, thereby stably maintaining the outflow amount of the additive, thereby maintaining the uniformity and consistency of beverage preparation.

[0070] Sixth, when the user drinks drinking water, the pores are opened to maintain the pressure of the drinking water storage space equal to the atmospheric pressure, thereby preventing uneven spitting of drinking water, thereby providing the user with stable drinking water intake.

[0071] Seventh, the drinking port is opened while the additive is sucked, and the pressure increase in the drinking water storage space caused by sucking the additive is eliminated through the drinking port, thereby preventing drinking water droplets from scattering through the pores that are micropores.

DETAILED DESCRIPTION

[0092] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0093] First, the beverage making suction cup according to the embodiment of the present invention is configured to be able to mix additives in drinking water or beverages and ingest them, such as Figure 1 As shown, the drinking water cartridge 100 may include a cover unit 200 and an additive cartridge 300 respectively coupled to the upper and lower parts of the drinking water cartridge 100 , and a suction unit 400 coupled to the drinking water cartridge 100 and the cover unit 200 .

[0094] The drinking water cylinder 100 is a main body of a cylindrical cup, and has a drinking water storage space formed therein so as to store drinking water or beverages.

[0095] The drinking water cylinder 100 is open at the top and shielded at the bottom, thereby forming a drinking water storage space for storing drinking water or beverages. A through hole 437 (see FIG. 4 ) communicating with the suction unit 400 is formed at the bottom of the bottom. Figure 5 ).

[0096] The cover unit 200 is detachably coupled to the upper portion of the drinking water cylinder 100 to shield the upper portion of the drinking water cylinder 100 , and forms a drinking port 211 through which a user can drink drinking water or beverages in the drinking water storage space.

[0097] In detail, the cover unit 200 may include a locking portion 210 , a rotating cover portion 220 , and a shielding support portion 230 .

[0098] The locking portion 210 is detachably combined with the drinking water cylinder 100 , and a drinking port 211 is formed through the upper surface so that the user can drink the stored beverage. The upper end of the suction unit 400 is formed through the other side of the drinking port 211 toward the upper side.

[0099] The accompanying drawings show an example in which the locking portion 210 is detachably coupled to the drinking water cylinder 100 by being threadedly coupled to each other, but this is only one embodiment, and various other detachable and airtight coupling methods such as snap coupling or button coupling can be used.

[0100] The rotating cover 220 is rotatably coupled to the upper portion of the locking portion 210 , and rotates around a rotating shaft 223 formed at the inner center of the lower end portion when an external force (user operation) is generated.

[0101] The rotating cover 220 is configured to have an opening 221 formed therein so that the upper portion of the locking portion 210 is exposed, and the drinking port 211 and the suction unit 400 are exposed through the opening 221 as the cover 220 rotates.

[0102] In the drawings, the lower portion of the rotating cover 220 is open in a cup shape, and the inner side surface of the lower portion and the upper surface of the locking portion 210 are rotatably coupled to the locking portion 210 in a state of contacting each other.

[0103] On the one hand, according to the relative rotational positions of the locking portion 210 and the rotating cover portion 220, the use state of the cover unit 200 can be divided into a storage mode and a use mode.

[0104] First, in the storage mode, the drinking port 211 and the suction unit 400 are shielded, thereby blocking the user's drinking water or beverage intake and the operation of the suction unit 400 , and the drinking port 211 is shielded by the shielding support part 230 .

[0105] In addition, the state of the use mode is: the drinking port 211 is opened through the opening 641 , and the user can take drinking water or beverages through the drinking port 211 , and at the same time the suction unit 400 is opened, and the user can operate the suction unit 400 .

[0106] When the suction unit 400 is operated, the drinking port 211 is opened, and the increased pressure inside the drinking water cylinder 100 caused by the suction is discharged through the drinking port 211 .

[0107] That is, when the pumping unit 400 is operated, the additive stored in the additive cartridge 300 flows into the drinking water cartridge 100 , and the pressure inside the drinking water cartridge 100 is increased.

[0108] At this time, the increased pressure makes it difficult for the user to inhale, and at the same time, the water is discharged through the air holes 213 as micropores described later, and the exhaled air and drinking water droplets are scattered together, so that there is a problem that the drinking water spray flows toward the periphery of the cup.

[0109] To this end, in the present invention, when the suction unit 400 is operated, the drinking port 211 is opened so that air flows through the drinking port 211 which is a relatively large hole, thereby maintaining the internal pressure of the drinking water cylinder 100 at a normal pressure.

[0110] On the one hand, the cover unit 200 switches between the storage mode and the use mode by rotating the rotating cover 220 .

[0111] exist Figure 3 In the illustrated embodiment, the cover unit 200 is illustrated as switching to the storage mode when it is rotated 180 degrees in the use mode, but the above-mentioned modes can obviously be variously constructed at the relative rotation position of the locking portion 210 and the rotating cover portion 220.

[0112] On the other hand, the shielding support portion 230 is configured to be located at the lower portion of the locking portion 210 , and is raised and lowered along the axial direction of the rotating cover portion 220 through the rotation of the rotating cover portion 220 , and plays a role in opening and closing the drinking port 211 when the rotating cover portion 220 rotates.

[0113] Reference Figure 2 In detail, the shielding support portion 230 may include a support body 231 , a shielding portion 233 , an air shielding portion 235 , a balance support portion 237 and a lock cover 239 .

[0114] First, the rotating shaft 223 is fixedly coupled to the rotating cover 220 , and the supporting body 231 is axially coupled to the rotating shaft 223 , and is lifted and lowered by the rotation of the rotating cover 220 .

[0115] To this end, the rotating shaft 223 is formed with a threaded portion along the outer circumference, and the inner circumference of the supporting body 231 is formed with a cam thread (not shown) that meshes with the threaded portion. The supporting body 231 rises and falls as the rotating shaft 223 rotates.

[0116] On the one hand, in the storage mode of the present invention, the drinking port and the air hole need to be kept in a covered state, and in the use mode, the drinking port and the air hole need to be in an open state.

[0117] To this end, one end of the shielding portion 233 is coupled to the outer side surface of the supporting body 231 , and the other end is extended from the one end to open and close the drinking port 211 .

[0118] In addition, the air shielding portion 235 is protrudingly coupled to the outer side surface of the supporting body 231 and is formed to be extended, so that the air hole 213 formed in the locking portion 210 is opened and closed by the rotation of the rotating shaft 223 .

[0119] The balancing support portion 237 is protrudingly coupled from the outer side surface of the supporting body 231 between the shielding portion 233 and the air shielding portion 235, and is raised and lowered around the rotating shaft 223 to prevent eccentricity and enable the shielding portion 233 and the air shielding portion 235 to stably shield the drinking port 211 and the air hole 213.

[0120] At this time, in order to improve the shielding effect when in close contact, the shielding portion 233, the air shielding portion 235 and the end of the balance support portion 237 may also be provided with a cover made of elastic material.

[0121] On the other hand, the locking portion 210 may be formed with a guide slit (not shown) for limiting the rotation of the shielding support portion 230 , so that when the rotating cover portion 220 rotates, the shielding support portion 230 does not rotate but only moves up and down.

[0122] The guide slit is a cylindrical shape with an open bottom and a vertical slit. The shielding portion 233, the air shielding portion 235 and the balance support portion 237 are inserted into the guide slit to guide the shielding support portion 230 to move up and down along the slit while limiting rotation.

[0123] On the one hand, the cover unit 200 may include a guide groove 215 and a stop protrusion (not shown) for preventing rotation, so as to guide the relative rotation position of the locking part 210 and the rotating cover part 220 to a set position in the usage mode and the storage mode, and prevent the rotating cover part 220 from excessive rotation.

[0124] The guide groove 215 is formed on the upper surface of the locking portion 210 and has an arc shape corresponding to a rotation radius of the rotating cover 220 in the use mode and the storage mode.

[0125] The stop protrusion may be configured to protrude toward the bottom of the rotating cover 220 and be embedded in the guide groove 642 , and be locked on the inner side surface of the guide groove 642 during rotation, thereby limiting the rotation angle of the rotating cover 220 .

[0126] like Figure 4 As shown, the guide groove 215 can be formed in a semicircular shape, so that the rotation angle of the rotating cover 220 is 180 degrees, corresponding to the rotation angle of the rotating cover 220 having a rotation angle of 180 degrees according to the use mode and the storage mode. However, this is only an embodiment, and it is obvious that the length of the rotating cover 220 can be set to correspond to the set rotation angle of the rotating cover 220.

[0127] On the other hand, although not shown, the guide groove 215 may include a structure capable of accommodating a stop protrusion, so that when the user rotates the rotating cover 630 in each mode, the user can intuitively perceive the position of the above-mentioned use mode and storage mode.

[0128] As an embodiment of such a structure, the guide groove 215 is formed with a wider width (width) for the positions of the above-mentioned respective modes than other portions, so that the stop protrusion is arranged at the positions of the respective modes.

[0129] Alternatively, as a different embodiment, the guide groove 215 may be formed to be deeper than other portions, so that the stop protrusion is placed at each mode position, etc. Various embodiments are possible.

[0130] As described above, the guide groove 215 and the stopper protrusion prevent the rotating cover 220 from excessively rotating, thereby preventing not only the shielding support 233 from being damaged but also the cover unit 200 from being accidentally disassembled and guiding the rotating cover 220 to rotate stably within the operation range.

[0131] On the one hand, in the use mode, at least any one of the side surface of the stop protrusion and the inner side surface of the guide groove 215 facing each other can be formed by an inclined surface, thereby reducing the external force of the stop protrusion escaping from the guide groove 215.

[0132] When a certain external force is applied to disengage, the inclined surface can enable the stop protrusion to move over the guide groove 215 .

[0133] That is, when the rotating cover portion 220 moves toward the usage mode, the shielding support portion 230 is in a state of moving downward, and when the rotating cover portion 220 moves further in this direction, the movement of the support body 231 is not restricted by the lock cover 239 described later, and the shielding support portion 230 moves further downward.

[0134] Then, when the rotating cover 220 further rotates in the same direction, the shielding support 230 is separated from the rotating shaft 223 , and the shielding support 230 , the rotating cover 220 , and the locking portion 210 are separated from each other.

[0135] Hereinafter, the structure of the suction unit for sucking the additive from the additive cartridge 300 and supplying the additive to the drinking water cartridge 100 according to the present invention will be described in detail.

[0136] The suction unit 400 is provided at the drinking water cylinder 100 and the cover unit 200 , and functions to suck the additive in the additive cylinder 300 and supply the additive to the inner space of the drinking water cylinder 100 .

[0137] The suction unit 400 is configured to quantitatively move the additive according to the user's suction and adjust the amount of the additive according to the number of suctions. Figure 2 and Figures 5 and 6 As shown, the suction unit 400 may be disposed along the length direction of the cover unit 200 and the drinking water cylinder 100 , and disposed at a position adjacent to the inner side surface of the drinking water cylinder 100 .

[0138] In detail, the suction unit 400 may include a suction button portion 410 and a suction portion 420 .

[0139] The suction button portion 410 is slidably and reciprocally disposed on the cover unit 200 and moves in response to pressure applied by a user.

[0140] The suction button portion 410 may include a rod portion 411 , a guide sleeve 413 , and an airtight component 415 .

[0141] The rod 411 is slidably disposed at the insertion port of the drinking water cylinder 100 , with its upper portion exposed to the outside of the drinking water cylinder 100 . A user presses the upper end portion to transfer external force to the lower portion of the suction portion 420 .

[0142] The guide sleeve 413 is in a tubular shape, and is configured to have the rod 411 inserted inwardly, guide the reciprocating rod 411, and be inserted into the upper inner side of the airtight member 415. The guide sleeve 413 may be configured such that the lower end side surface of the flange portion formed at the upper end contacts the upper surface of the insertion port, and is fixedly supported at the insertion port.

[0143] The guide sleeve 413 fixes the upper end of the airtight component 415 to the inner circumference of the insertion port through the flange portion, and reduces the friction with the airtight component 415 when the rod portion 411 moves in the up and down directions, thereby providing an effect of preventing damage to the airtight component 415.

[0144] At this time, the suction button portion 410 and the suction portion 420 are divided into an outside and an inside of the drinking water storage space by the airtight member 415 formed of an elastically deformable soft film.

[0145] The airtight component 415 is formed in the shape of a cylindrical tube with an open upper portion and a closed lower portion. The suction button portion 410 is inserted toward the inner side. The lower surface of the suction button portion 410 contacts the bottom surface, and the lower end surface contacts the suction portion 420.

[0146] The airtight member 415 may be formed of a bellows having a plurality of folds formed on the outer peripheral surface along the circumferential direction so as to be able to expand and contract in the up-and-down direction.

[0147] Thus, while the physical force can be transmitted, the drinking water in the drinking water storage space is prevented from flowing out toward the suction button portion 410 .

[0148] On the other hand, the suction part 420 is located in the drinking water storage space of the drinking water cylinder 100, and is raised and lowered by the reciprocating movement of the suction button part 410, and is respectively connected to the drinking water storage space and the additive storage space, thereby playing the role of sucking the additive through lifting and lowering and making it flow toward the drinking water storage space.

[0149] To this end, the suction part 420 may include a piston part 430 and a discharge pipe 440 .

[0150] The piston portion 430 is located in the drinking water storage space and communicates with the additive cartridge 300 , so as to have the following functions: through the reciprocating movement of the suction button portion 410 , the additive is sucked from the additive cartridge 300 and the sucked additive flows out toward the discharge pipe 440 .

[0151] The piston portion 430 may include a piston rod 431 , a piston housing 433 , and an elastic member 435 .

[0152] The piston rod 431 is linked to the suction button portion 410 so as to be raised and lowered by the reciprocating movement of the suction button portion 410 and inserted into the internal space of the piston housing 433, and a flow path is formed inside so that the additive in the piston housing 433 can be moved during suction.

[0153] The piston housing 433 has a piston rod 831 disposed in an ascending and descending manner in its inner space, a through hole is formed at the lower end thereof and is communicated with the additive cartridge 300 , and the piston rod is combined with the upper portion thereof.

[0154] Thus, the piston housing 433 allows the additive in the additive cartridge 300 to flow into the internal space due to the change in internal pressure caused by the ascending and descending of the piston rod 431 .

[0155] In addition, the discharge pipe 440 is a hollow pipe, which is extended from the end of the piston part 430 in a "U" shape, so that the sucked additive flows out toward the drinking water storage space.

[0156] In addition, the upper end portion (the “U”-shaped curved portion) of the discharge pipe 440 is linked to the suction button portion 410 and is lifted and lowered by the reciprocating motion of the suction button portion 410 , thereby pressurizing the piston portion 430 .

[0157] On the one hand, the suction part 420 moves due to the flow of additives into the interior, and needs to be cleaned after a certain degree of use or when the additives are replaced.

[0158] For this reason, Figure 6 As shown, the upper end surface ("U"-shaped curved surface) of the discharge pipe 440 is provided with an openable and closable opening and closing plate 441. When cleaning the suction part 420, the opening and closing plate 441 is opened, thereby making it easy to clean the piston part 430 and the discharge pipe 440.

[0159] In addition, preferably, during cleaning, the piston rod 431 and the elastic member 435 are separated from the piston housing 433 , and for this purpose, the piston rod 431 and the piston housing 433 are detachably combined.

[0160] Specifically, a fastening ring 451 is coupled to the piston rod 431 so as to be liftable along the piston rod 431 , and a fastening groove 460 is formed on the inner peripheral side surface of the upper end portion of the piston housing 433 .

[0161] Furthermore, the piston rod 431 and the piston housing 433 are coupled to each other by inserting a fastening protrusion 453 protruding from a side surface of the fastening ring 451 into a fastening groove 460 formed in the piston housing 433 .

[0162] At this time, if Figure 6As shown, the fastening groove 460 includes: an upper cut portion 461, which is formed by cutting with a size corresponding to the width of the fastening protrusion, so that the fastening protrusion 453 can be inserted from the upper outside; a horizontal slit 463, which extends from the lower end of the upper cut portion 461 toward the horizontal direction, so that the fastening protrusion 453 inserted into the upper cut portion 461 moves by rotation; and a vertical placement portion 465, which extends toward the upper side of the end of the horizontal slit 463, so that the fastening protrusion 453 moving along the horizontal slit 463 is moved upward and placed by the elastic force of the elastic member 435, thereby limiting the rotational movement.

[0163] When the piston rod 431 is repeatedly pumped in a state of being fastened to the piston housing 433 , the vertical placement portion 465 maintains the stability of the combination of the piston housing 433 and the piston rod 431 .

[0164] Specifically, when the piston rod 431 reciprocates by suction, the force applied to the discharge pipe 440 is detached from the center of the piston rod, causing eccentricity. Such eccentricity generates a rotational force on the fastening ring 451, which may cause the piston housing 433 and the piston rod 431 to separate without the user's intention.

[0165] However, when the fastening protrusion 453 is placed on the vertical placement portion 465, even if a simple rotational force is generated at the fastening ring 451, the fastening ring 451 will not rotate, thereby preventing the piston housing 433 and the piston rod 431 from being separated.

[0166] On the other hand, the elastic member 435 is located inside the piston housing 433 and is combined with the piston rod 431, thereby providing a restoring force so that the piston rod 431 can move upward after being pressurized and moved downward.

[0167] On the one hand, in the present invention, the through hole 437 penetrating the lower portion of the piston housing 433 and the lower portion of the drinking water cylinder 100 and the additive cylinder 300 are connected via the suction pipe module 500 .

[0168] Hereinafter, the structure of the suction pipe module for connecting the additive cartridge 300 and the drinking water cartridge 100 according to the present invention will be described in detail.

[0169] like Figure 7 As shown, the suction pipe module 500 includes a combining plate 510 , an expansion plate 520 , a suction pipe 530 and an elastic cover 540 .

[0170] The coupling plate 510 is formed in a circular plate shape and is detachably coupled to the lower end of the drinking water barrel 100. An elastic cover 540 is coupled to the upper outer portion of the coupling plate 510. The elastic cover 540 is formed of an elastic material and improves the adhesion of the lower end of the drinking water barrel 100.

[0171] At this time, the elastic cover 540 and the combining plate 510 are combined with each other with a preset interval space formed therebetween.

[0172] In addition, a circular expansion plate 520 is coupled to the center of the lower portion of the coupling plate 510 and is detachable by means of screw coupling.

[0173] In addition, the coupling plate 510 includes a suction tube 530 in the form of a circular tube, whereby the suction tube 530 passes through an additive capsule 700 or a shielding cover 600 described later, and the expansion plate 520 is closely attached to the passing portion, thereby preventing the additive from being exposed to the outside.

[0174] To this end, the lower end of the expansion plate 520 may be formed by a protruding curved surface 521 in which the lower surface is protruded with a curved surface centered at the central portion, thereby improving the adhesion.

[0175] At this time, the combining plate 510 , the expansion plate 520 , and the suction pipe 530 form an inflow passage that connects the combining plate 510 , the expansion plate 520 , and the suction pipe 530 and moves the additive, and the additive flows into the suction unit 420 through the through hole 437 .

[0176] On the other hand, the suction pipe 530 may be formed of a tapered circular pipe whose width gradually narrows slightly downward.

[0177] At this time, when the suction tube 530 penetrates the additive capsule 700 or the shielding cover 600, the deeper the penetration depth is, the stronger the adhesion force of the penetration part is, so that the risk of the additive flowing out can be reduced.

[0178] In addition, an opening and closing ball valve 550 may be provided inside the connection portion of the expansion plate 520 connected to the connection plate 510 to selectively open and close the additive inflow passage.

[0179] The on-off ball valve 550 selectively opens and closes the inflow path in the suction pipe 530 as the piston rod 431 rises and falls. When positive pressure is generated in the suction pipe 530, the on-off ball valve 550 rises to open the inflow path. When negative pressure is generated, the on-off ball valve 550 falls to block the inflow path.

[0180] Thus, the inflow flow path is formed only in the direction in which the additive flows into the drinking water cylinder 100 .

[0181] Hereinafter, the structure of the additive cartridge of the present invention, which is coupled to the lower part of the drinking water cartridge and provides additives to the drinking water cartridge, will be described in detail.

[0182] like Figure 8 and 9 As shown, the additive cartridge 300 is open at the top and shielded at the bottom, with the additive storage space formed inwardly, and is detachably coupled to the bottom of the drinking water cartridge 100 by means of threaded coupling or the like.

[0183] On the one hand, in the present invention, the additive cartridge 300 can be divided into two embodiments according to the operation mode.

[0184] First, the first embodiment is an embodiment in which the additive cartridge 300 is directly filled with additives and used.

[0185] In this case, since there is a risk that the additive is exposed to the outside of the additive cartridge 300 , the present invention further includes a shielding cover 600 .

[0186] The shielding cover 600 is used to prevent the additives contained in the additive cylinder 300 from flowing out, and is formed of a circular plate made of elastic material, so as to be pressed into the upper part of the additive cylinder 300 .

[0187] At this time, a central through hole 610 through which the suction pipe 530 can pass is formed at the center of the shielding cover 600 .

[0188] In addition, the central portion of the upper surface of the shielding cover 600 may be formed by a concave surface 620 corresponding to the shape of the protruding curved surface 521 of the lower portion of the expansion plate 520 , thereby improving the close contact with the expansion plate 520 .

[0189] On the other hand, preferably, the shielding cover 600 has a gripping portion 630 on its upper surface for gripping when taking out the shielding cover 600 , so that the shielding cover 600 can be easily taken out.

[0190] In addition, the shielding cover 600 may include a flow path cutout portion 650 that allows air to move in only one direction from the upper portion to the lower portion.

[0191] like Figure 8 As shown, the flow path cutout 650 may be formed by a pair of wings that are plucked and contacted with each other toward the bottom of the shielding cover 600. Thus, when negative pressure is generated at the bottom of the shielding cover 600, the air at the top of the shielding cover 600 moves downward through the flow path cutout 650, but the additives at the bottom of the shielding cover 600 are prevented from moving toward the top of the flow path cutout 650.

[0192] When the flow path cutout portion 650 is formed, even if a cut surface is not formed on the suction pipe 530, since a flow path from the upper side to the lower side of the shield cover 600 is formed, a part F4 of the normal pressure flow path described later can be constituted.

[0193] Next, the second embodiment of the additive cartridge is an embodiment in which an additive capsule 700 consisting of a disposable container storing an additive is inserted into the additive cartridge 300 and used.

[0194] In such a case, in the additive cartridge 300 , the user does not put the additive stock solution into the additive cartridge, but inserts the additive capsule 700 containing the additive stock solution purchased from the manufacturer into the additive cartridge 300 , thereby making it possible to use the additive in a simple manner.

[0195] At this time, if Fig. 9 As shown, the additive capsule 700 may include a container portion 710 that contacts the inner side surface and the bottom surface of the additive cartridge; and a cover film 720 that covers the upper surface of the container portion 710 .

[0196] The cover film 720 is a portion that is perforated by the pressure of the suction pipe 530 and is welded and attached to the upper end of the container portion 710 by a soft synthetic resin film.

[0197] At this time, the side wall of the container portion 710 includes a protrusion protruding outward from the upper portion of the outer circumference thereof, and a step portion disposed on the inner side surface of the additive cartridge 300 may be formed at the boundary of the protrusion.

[0198] In addition, if Fig. 9 As shown in the enlarged figure, a placement portion 730 is formed at the upper edge of the side wall of the container portion 710, which is used to be placed at the upper edge of the additive cartridge 300.

[0199] At this time, the placement portion 730 may include: a horizontal plate 731 extending parallel to the upper end of the side wall toward the outside by a distance equivalent to the thickness of the upper edge of the additive cartridge 300; and a vertical plate 733 extending downward by a preset distance from the end of the horizontal plate 731, so that the additive capsule 700 can be combined with the additive cartridge 300 in a state where the placement portion 730 wraps the upper end of the additive cartridge 300.

[0200] On the other hand, in the description of the state in which the additive cartridge 300 and the drinking water cartridge 100 are separated, at this time, the additive capsule 700 inserted into the additive cartridge 300 generates friction with the additive cartridge 300 and also generates friction with the suction tube 530 .

[0201] At this time, when the friction between the additive capsule 700 and the suction tube 530 is greater, the additive capsule 700 is attached to the suction tube 530, and the additive cartridge 300 and the drinking water cartridge 100 are separated, thereby increasing the risk of the additive capsule 700 falling to the ground or the additive being exposed to the outside.

[0202] In order to prevent such a situation, in the present invention, in order to improve the bonding force between the additive cartridge 300 and the additive capsule 700 , a locking shoulder 750 and a locking protrusion 740 may be formed on the container portion 710 and the additive cartridge 300 .

[0203] That is, Fig.10 As shown, a locking shoulder 750 and a locking protrusion 740 are formed at positions corresponding to each other on the outer side surface of the container portion 710 and the inner side surface of the additive cartridge 300 when combined, so that when the additive cartridge 300 is separated from the drinking water cartridge 100, the locking protrusion 740 is supported on the locking shoulder 750, and the additive capsule 700 can be stably located in the additive cartridge 300.

[0204] On the other hand, when the locking shoulder 750 is formed on the inner side of the additive cartridge 300 , the locking shoulder is provided with the outer peripheral surface of the shielding cover 600 inserted into the additive cartridge 300 , and can also play a role in supporting the insertion position of the shielding cover 600 .

[0205] Furthermore, when the additive cartridge 300 and the drinking water cartridge 100 are threadedly coupled, the outer side of the elastic cover 540 is located between the upper end surface of the additive cartridge 300 and the outer lower side of the drinking water cartridge 100 .

[0206] Thus, through the threaded coupling force between the additive cartridge 300 and the drinking water cartridge 100 , the outer side of the elastic cover 540 made of elastic material is pressurized, thereby improving the sealing force of the inner space of the additive cartridge 300 .

[0207] On the one hand, regardless of the embodiment of the additive cartridge 300, the additive cartridge 300 may further include an additive cartridge cover 800, which is used to cover the upper portion of the additive cartridge 300 when the additive cartridge 300 is separated from the drinking water cartridge 100, thereby ensuring the independent portability of the additive cartridge.

[0208] The additive cartridge cover 800 is a cover of the additive cartridge 300 , and is threadedly coupled to the additive cartridge 300 . A pressing protrusion 810 protruding downward in a hemispherical shape of a curved surface may be formed at the center of the inner side surface, and is used to shield the through hole on the upper part of the additive capsule 700 or the through hole of the shielding cover 600 .

[0209] Thus, the additive cartridge 300 and the drinking water cartridge 100 can be separated and safely carried and stored separately.

[0210] In the present invention, as the suction unit 400 sucks the additive from the additive cartridge 300 and supplies it to the drinking water storage space, negative pressure is formed inside the additive cartridge 300, and the suction of the additive cannot be performed smoothly. As a result, the amount of the additive flowing out in one suction is reduced, making the outflow amount uneven, and making it difficult to prepare a fixed amount of mixed beverage. In addition, when the additive cartridge 300 is to be replaced, it is difficult to open the additive storage space due to the internal pressure.

[0211] Therefore, preferably, the additive cartridge according to the present invention forms a normal-pressure flow path when negative pressure is generated, thereby allowing external air to flow in and maintaining the pressure inside the additive cartridge at normal pressure.

[0212] Hereinafter, the normal-pressure flow path structure for maintaining normal pressure inside the additive cartridge 300 of the present invention when the additive is sucked from the additive cartridge will be described in detail.

[0213] In the present invention, for the convenience of explanation, the normal pressure flow path is divided into four steps from the first normal pressure flow path to the fourth normal pressure flow path for explanation.

[0214] First, the first normal-pressure flow path F1 is a flow path through which external air can flow from the outside into the connection space between the lower portion of the drinking water cartridge and the additive cartridge.

[0215] In addition, the second normal-pressure flow path F2 is a flow path that communicates with the first normal-pressure flow path F1 and allows the inflowing external air to flow toward the space between the elastic cover and the coupling plate.

[0216] The third normal-pressure flow path F3 is a flow path that communicates with the second normal-pressure flow path F2 and allows the inflowing external air to move toward the internal space of the additive cartridge at the lower portion of the coupling plate.

[0217] Finally, the fourth normal-pressure flow path F4 is a flow path that communicates with the third normal-pressure flow path F3 and moves the air in the internal space of the additive cartridge toward the inside of the additive capsule.

[0218] That is, in the present invention, the normal pressure flow path is formed by combining the first to fourth normal pressure flow paths, and the normal pressure flow path of the present invention is roughly divided into three types according to the structure realized by each detail of the normal pressure flow path.

[0219] Hereinafter, various embodiments of the normal pressure flow path will be described in detail.

[0220] First, if Fig.12As shown, the flow path of the first embodiment of the normal pressure flow path is constructed as follows: F1, external air flows into the space between the elastic cover 540 and the drinking water cylinder 100 through the inflow hole 110 on the side of the drinking water cylinder 100; F2, the inflowing air moves toward between the elastic cover 540 and the connecting plate 510 through the vertical connecting hole 545 of the elastic cover 540; F3, the moving air moves toward the lower part of the connecting plate 510 through the elastic button 560; F4, the moving air moves along the flow path groove 525 of the expansion plate 520 and the cutting surface of the suction pipe 530 toward the lower part of the shielding cover 600 or the inside of the additive capsule 700.

[0221] For this reason, Fig.13 As shown, in the side surface of the drinking water cylinder 100, an inflow hole 110 for letting in external air is formed at the interval space between the elastic cover 540 and the lower end of the drinking water cylinder 100.

[0222] In addition, in order to form a spacing space outside the lower end of the drinking water cylinder 100, the elastic cover 540 of the suction pipe module 500 has a portion of the upper surface of the elastic cover 540 or the lower surface of the outer side of the drinking water cylinder 100 formed by a step surface or an inclined surface (refer to Fig.16 ).

[0223] In addition, in order to form the second normal pressure flow path F2, the elastic cover 540 is formed with a vertical connecting hole 545, which connects the interval space between the elastic cover 540 and the lower end of the drinking water cylinder 100 and the space between the lower part of the elastic cover 540 and the connecting plate 510.

[0224] On the one hand, in order to form the third normal pressure flow path F3, the coupling plate 510 has an elastic button 560, which is a kind of pressure valve, and is elastically deformed by the air pressure difference between the upper and lower parts of the coupling plate 510, so as to be selectively opened and closed.

[0225] Furthermore, in the present invention, in order to form the fourth normal pressure flow path, the flow path groove 523 is formed on the coupling plate 510 , and the cutting surface 531 is formed on the upper end of the suction pipe 530 .

[0226] The flow groove 523 is formed from the outer end of the protruding curved surface 521 of the expansion plate 520 toward the center. At the close contact surface of the expansion plate 520, air can move to form a flow path. The cutting surface 531 is formed by cutting the outer peripheral surface of the circular suction pipe 530. It is formed from the end of the flow groove 523 downward to a preset length, forming a space on the through surface of the suction pipe 530.

[0227] Next, if Fig.14As shown, the flow path of the second embodiment of the normal pressure flow path is constructed as follows: F1, external air flows in through the joint of the drinking water cylinder 100 and the additive cylinder 300, passes through the spacing groove 541 of the elastic cover 540, and flows into the space between the elastic cover 540 and the drinking water cylinder 100; F2, the inflowing air moves toward between the elastic cover 540 and the connecting plate 510 through the vertical connecting hole 545 of the elastic cover 540; F3, the moving air moves toward the lower part of the connecting plate 510 through the elastic button 560; F4, then moves along the flow path groove 525 of the expansion plate 520 and the cutting surface of the suction pipe 530 toward the lower part of the shielding cover 600 or the inside of the additive capsule 700.

[0228] To this end, a spacing space is formed between the joint surfaces and joint ends of the drinking water cartridge 100 and the additive cartridge 300 , and external air flows in through the spacing space.

[0229] At this time, the inflowing air needs to flow into F1 through the inner side of the lower part of the drinking water cylinder and the outer side of the elastic cover toward the space between the elastic cover 540 and the drinking water cylinder 100. For this purpose, Fig.16 As shown, a spacing groove 541 through which external inflowing air can move is formed at a portion of the joint surface between the inner side surface of the lower portion of the drinking water cylinder 100 and the outer side surface of the elastic cover 540.

[0230] Then, since the second normal-pressure flow path F2, the third normal-pressure flow path F3 and the fourth normal-pressure flow path F4 are the same as those of the first embodiment of the normal-pressure flow path, their detailed description is omitted.

[0231] On the other hand, the formation of the spacing space between the joining surface and the joining end of the drinking water cylinder 100 and the additive cylinder 300 is described. The spacing space formed between the joining end of the drinking water cylinder 100 and the additive cylinder 300 can be formed by the step difference of the joining end of the drinking water cylinder 100 and the additive cylinder 300.

[0232] That is, the space is formed such that the length of the connecting portion of the additive cartridge 300 is greater than the length of the connecting portion of the drinking water cartridge 100 .

[0233] At this time, since the upper end joint surface of the additive cartridge 300 is provided with an elastic cover 540, the joint step difference is formed according to the difference obtained by subtracting (-) the length of the thread joint height of the inner side of the lower part of the drinking water cylinder 100 from the sum of the thread joint height of the upper outer side of the additive cartridge 300 and the height of the outer side surface of the elastic cover 540.

[0234] At this time, when the additive cartridge 300 and the drinking water cartridge 100 are combined with a greater force, the combined step difference will be reduced.

[0235] On the one hand, preferably, the coupling step difference is about 1 to 10 mm, so as to maintain a stable coupling force between the additive cartridge 300 and the drinking water cartridge 100 , while forming an inflow of air and changing through the threaded coupling.

[0236] Furthermore, the spacing space formed between the coupling surfaces of the drinking water cartridge 100 and the additive cartridge 300 is formed by the gap between the coupling threads of the drinking water cartridge 100 and the additive cartridge 300 .

[0237] At this time, the gap spacing of the combined thread lines can be formed by the space between the thread lines, or can be formed by the space between the thread lines. Fig.15 As shown, the upward gap spacing is formed by removing a part of the thread line.

[0238] That is, Fig.15 As shown, the interval space formed between the combined ends of the drinking water cartridge 100 and the additive cartridge 300 may be formed by one or more inlet cutouts 120 formed by minutely cutting the combined ends of the drinking water cartridge 100 and the additive cartridge 300 .

[0239] Finally, if Fig.17 As shown, the flow path of the third embodiment of the normal pressure flow path is constructed as follows: F1, external air flows in through the joint of the drinking water cylinder 100 and the additive cylinder 300, and flows into the space between the side of the elastic cover 540 and the inner side of the side of the drinking water cylinder 100; F2, the inflowing air moves toward the space between the elastic cover 540 and the connecting plate 510 through the horizontal connecting hole 545 of the elastic cover 540; F3, the moving air moves toward the lower part of the connecting plate 510 through the elastic button 560; F4, the moving air moves toward the lower part of the shielding cover 600 or the inside of the additive capsule 700 along the flow path groove 525 of the expansion plate 520 and the cutting surface of the suction pipe 530.

[0240] Since the formation of the space between the joint surfaces and the joint ends of the drinking water cartridge 100 and the additive cartridge 300 is the same as that of the second embodiment of the normal pressure flow path, the detailed description thereof is omitted.

[0241] On the other hand, the air flowing into the space between the side of the elastic cover 540 and the inner side of the side of the drinking water cylinder 100 moves toward the space between the elastic cover 540 and the connecting plate 510 through the horizontal connecting hole 545 of the elastic cover 540, and forms a second normal pressure flow path. Fig.18 As shown, a horizontal connecting hole 547 is formed on the side of the elastic cover 540 , which connects the space between the lower part of the outer side of the elastic cover 540 and the lower inner side of the drinking water barrel 100 , and the space between the lower part of the elastic cover 540 and the combining plate 510 .

[0242] In addition, if Fig.18 As shown, in the side surface of the elastic cover 540, the upper part is tightly attached to the inner circumference of the drinking water cylinder 100, and the lower part is separated from the inner circumference of the drinking water cylinder 100 to form a space, and the horizontal connecting hole 547 is formed at the lower part of the side surface of the elastic cover 540 that forms the space.

[0243] At this time, the upper side of the elastic cover 540 can form one or more wings and fit tightly against the inner circumference of the drinking water barrel 100 , and the upper side of the elastic cover 540 as a whole can also fit tightly against the inner circumference of the drinking water barrel 100 .

[0244] Then, since the third normal-pressure flow path F3 and the fourth normal-pressure flow path F4 are the same as the normal-pressure flow paths of the first embodiment and the second embodiment described above, their detailed description will be omitted.

[0245] The present invention forms a normal pressure flow path as described above, and external air flows into the additive storage space during suction, eliminating the negative pressure (vacuum pressure) formed inside, thereby allowing suction to proceed smoothly and stabilizing the outflow of the suctioned additive, making the additive cartridge 300 easy to open.

[0246] The present invention is described with reference to the embodiments shown in the accompanying drawings, but this is only exemplary, and a person with ordinary knowledge in the technical field should understand that various modifications and other equivalent embodiments can be made therefrom. Therefore, the true technical protection scope of the present invention should be determined according to the technical ideas of the claims.
