DETAILED DESCRIPTION OF THE INVENTION

(13) Preferred embodiments of the present invention are illustrated in detail below in combination with drawings, so that advantages and features of the present invention are easier to be understood by those skilled in the art, so as to define a protection scope of the present invention more clearly.

(14) As shown in FIG. 1, a bottom-up liquid infusion system in the present embodiment comprises a two-portion structure: a container portion 100 and an infusion portion 200.

(15) As shown in FIG. 1 to FIG. 5, the first portion is the container portion 100:

(16) the container portion 100 comprises: a container upper body 110 and a container lower body 120. The container upper body 110 is connected with the container lower body 120. Specifically, the container upper body 110 is arranged in the container lower body 120. As shown in FIG. 3, the bottom layer portion of the container upper body 110 is provided with two upper circulating holes 111 and two upper protruding plugs 112. In the present embodiment, two pairs of upper and lower circulating holes, two pairs of upper and lower protruded hole plugs, two infusion portions, and two circulating holes are provided, and certainly, the number thereof can also be 3, 4 and the like according to own needs. Correspondingly, the bottom layer portion of the container lower body 120 is provided with two lower circulating holes 121 corresponding to upper circulating holes 111, and two lower protruding plugs 122 corresponding to upper protruding plugs. The height of the container upper body 110 shall be higher than the height of the container lower body 120, which is convenient for operators to rotate the container upper body 110 along the container lower body 120 in a circumferential direction through an external force which acts on the container upper body 110, or otherwise rotate the container lower body 120 along the container upper body 110 in a circumferential direction in other methods, as shown by X direction in FIG. 11. Through rotation, two upper circulating holes 111 and two upper protruding plugs 112 can be converted from a circulation state corresponding to two lower circulating holes 121 and two lower protruding plugs 122 into a blocking state corresponding to the two lower protruding plugs 122 and the two lower circulating holes 121. When the liquid needs to be perfused into the container portion 100 (specifically, the container upper body 110), the container upper body 110 and the container lower body 120 are converted into the circulation state, i.e., two upper circulating holes 111 correspond to two lower circulating holes 121, and two upper protruding plugs 112 correspond to two lower protruding plugs 122; and after the container portion 100 (specifically, the container upper body 110) is filled with the liquid and needs to stop filling, the container upper body 110 and the container lower body 120 are converted into the blocking state, i.e., two upper circulating holes 111 and two lower protruding plugs 122 are correspondingly blocked by the lower protruding plugs 122, and two lower circulating holes 121 and two upper protruding plugs 112 are correspondingly blocked by the upper protruding plugs 112. See the following practical application for the specific principle.

(17) In the container portion 100, to ensure that the container upper body 110 and the container lower body 120 will not be moved before application when the container upper body 110 and the container lower body 120 are in the circulation state, as shown in FIG. 4, end surfaces of the upper protruding plugs 112 and the lower protruding plugs 122 are provided with structures of bulges 124 and recesses 114 which are matched mutually. In addition, the shapes of the end surfaces of the upper protruding plugs 112 are planes 115 consistent with the shapes of the upper circulating holes 111; the shapes of the planes 115 in the present embodiment are circular shapes; and correspondingly, the shapes of the end surfaces of the lower protruding plugs 122 are planes consistent with the shapes of the lower circulating holes 121. The two structures aim to prevent the container upper body 110 and the container lower body 120 from moving, and can ensure that the liquid can smoothly enter the container portion 100 (i.e., enter the container upper body 110).

(18) As shown in FIG. 2, the container upper body 110 and the container lower body 120 relatively rotate through cooperation of a clamping groove 113 and a flange 123. To facilitate rotation and reduce the cost of the container portion 100, the container upper body 110 and the container lower body 120 are made of plastics or other low-cost materials.

(19) As shown in FIGS. 6-8, the second portion is an infusion portion 200:

(20) The infusion portion 200 comprises: an upper connecting member 220, a telescopic elastic element 230 and a lower connecting element 240 which are correspondingly arranged from top to bottom. As shown in FIG. 8, the upper connecting member 220, the telescopic elastic element 230 and the lower connecting element 240 are respectively provided with an upper-layer through hole 221, a middle-layer through hole 231 and a lower-layer through hole 241. A lower end of the lower-layer through hole 241 is connected with a liquid circulating pipe 250. The liquid can flow into the container portion 100 successively from the liquid circulating pipe 250, the lower-layer through hole 241, the middle-layer through hole 231, the upper-layer through hole 221 and two pairs of corresponding upper and lower circulating holes 121. Specifically, an upper end surface of the upper-layer through hole 221 has two infusion nozzles 222, i.e., the liquid can flow into the container portion 100 successively from the liquid circulating pipe 250, the lower-layer through hole 241, the middle-layer through hole 231, two infusion nozzles 222 of the upper-layer through hole 221 and two pairs of corresponding upper and lower circulating holes 111, 121, wherein the upper-layer through holes 221 in the present embodiment have a shape of a funnel, and can also present different shapes and capacities according to individual applications, and the telescopic elastic element 230 can be expanded and contracted. Specifically, the telescopic elastic element 230 adopts an elastic plastic element; a spring 232 used for expansion is arranged in the telescopic elastic element 230; and the spring 232 can also be applied and arranged in other places in the infusion portion 200. A fixing position 242 for installing a connecting rod 244 is arranged in the lower-layer through hole 241. The fixing position 242 is a connecting hole. The aperture of the connecting hole is smaller than the aperture of the lower-layer through hole 241. The liquid flows from the lower-layer through hole 241 except for the fixing position 242 into the middle-layer through hole 231. The connecting rod 244 shown in FIG. 12 is screwed in the fixing position 242. As shown in FIGS. 10 and 11, an upper end of the connecting rod 244 penetrates through the middle-layer through hole 231 and extends into the upper-layer through hole 221; and an infusion circulating plug 245 is arranged on the upper end of the connecting rod 244 located in the upper-layer through hole 221. As shown in FIG. 12, the infusion circulating plug 245 in the present embodiment is connected with the upper end of the connecting rod 244 through a screwing manner, which is convenient for replacing the infusion circulating plug 245 once the infusion circulating plug 245 is damaged. When the telescopic elastic element 230 is expanded through elasticity released by the spring 232, the infusion circulating plug 245 can block the upper-layer through hole 221; otherwise, when an external force acts downwards on the container portion 100, the telescopic elastic element 230 is contracted and the infusion circulating plug 245 will not block the upper-layer through hole 221. At this moment, the liquid can flow into the container portion 100 (the container upper body 110) successively from the lower-layer through hole 241, the middle-layer through hole 231, two infusion nozzles 222 of the upper-layer through hole 221 and two pairs of corresponding upper and lower circulating holes 121.

(21) To avoid influencing the taste of the liquid because the connecting rod 244 and the infusion circulating plug 245 get rusty after soaked in the liquid for a long time, the connecting rod 244 adopts antirust metal, and certainly can adopt other rustless materials according to individual application design.

(22) When the infusion nozzles 222 are installed, two installation ports shall be formed in advance in the upper end surface of the upper connecting member 220, while the quantity of the infusion nozzles 222 can be defined according to individual application design; two infusion nozzles 222 are screwed with the installation ports; two infusion nozzles 222 correspond to two lower circulating holes 121; and the infusion nozzles 222 are slightly higher than the upper circulating holes 111, to ensure that the infusion nozzles 222 are pressed when the container portion 100 is pressed so that the infusion nozzles 222 spray the required liquid into the container upper body 110. infusion nozzle sleeves 225 made of elastic material are respectively arranged on the two infusion nozzles 222. Once the lower circulating hole 121 is aligned, the arrangement of the infusion nozzle sleeves 225 made of elastic material ensures that the infusion nozzles 222 and the lower circulating hole 121 are not easy to move, wherein the infusion nozzle sleeves 225 can adopt infusion nozzle sleeves of rubber material, and more specifically, can adopt infusion nozzle sleeves of silicone.

(23) The infusion portion 200 further comprises a container fixing element 210; and the container fixing element 210 is used to contain the container lower body 120. As shown in FIGS. 9-11, the container fixing element 210 is buckled with an outer wall of the upper connecting member 220 through a button 211. In the present embodiment, the button 211 adopts a metal button, two circulating portions 212 for correspondingly circulating the infusion nozzles 222 and two lower circulating holes 121 are arranged in the container fixing element 210, wherein the top material of the container fixing element 210 adopts silicone rubber material, and can also adopt other different materials according to individual application design. The bottom material of the container fixing element 210 adopts heat-resistant elastic silicone rubber material, and can also adopt other different materials according to individual application design. The edge of the lower end surface of the container fixing element 210 adopts an antirust metal ring, and can also adopt other different antirust materials according to individual application design to prevent rust.

(24) As shown in FIG. 8, the telescopic elastic element 230 has a containing cavity 236 along a circumference of the middle-layer through hole 231. The spring 232 is arranged in the containing cavity 236, and can also be used for supporting or expansion in other positions in the infusion portion 200 according to individual application design. A plurality of sliding connecting elements are also arranged in the containing cavity 236. The sliding connecting elements penetrate through the upper end surface of the telescopic elastic element 230 and are connected with the upper connecting member 220. The upper connecting member 220 can move along the sliding connecting elements towards a direction close to or away from the telescopic elastic element 230. The sliding connecting elements comprise a connecting rod 237 arranged on a bottom of the upper connecting member 220, and a fixed supporting column 233 arranged in the containing cavity 236 of the telescopic elastic element. The connecting rod 237 and the fixed supporting column 233 are vertically arranged. A lower end of the connecting rod 237 is provided with a connecting column 238 perpendicular to the lower end. The fixed supporting column 233 is provided with a sliding groove 234 which runs in an up-down direction. The connecting column 238 is clamped in the sliding groove 234, and can move up and down along the sliding groove 234. Similarly, to prevent the sliding connecting elements from getting rusty, the sliding connecting elements adopt antirust metal, and can also adopt other different antirust materials according to individual application design.

(25) To prevent the liquid from flowing into the container portion 100 (the container upper body 110) successively from the lower-layer through hole 241, the middle-layer through hole 231, two infusion nozzles 222 of the upper-layer through hole 221 and two pairs of corresponding upper and lower circulating holes 111, 121, waterproof rings 223, 235 are arranged between the upper-layer through hole 221 and the middle-layer through hole 231, waterproof rings 235, 243 are arranged between the middle-layer through hole 231 and the lower-layer through hole 241, a waterproof ring 246 is arranged between the infusion circulating plug 245 and the upper-layer through hole 221 and a waterproof ring 224 is arranged between the infusion nozzles 222 and the upper connecting member 220. Specifically, the material of the waterproof rings can adopt silicone rubber material, and can also adopt other different materials according to individual application design.

(26) The applicable range of the bottom-up liquid infusion system includes, but not limited to: 1) the application of infusion/packing of all kinds of beverages and other needs; and 2) the application of infusion of other liquids.

(27) Specific Operation Process is Divided into Two Portions.

(28) Step A: Installation

(29) step 1: the container portion 100 does not need any assembly by a user; the user can check whether the container portion 100 is in a right and appropriate use phase during supply; two upper circulating holes 111 of the container upper body 110 and lower circulating holes 121 of the container lower body 120 shall be in corresponding positions; meanwhile, two upper protruding plugs 112 of the container upper body 110 and two lower protruding plugs 122 of the container lower body 120 are also corresponding and are mutually abutted; and this is a right phase before use of the cup;

(30) step 2: the infusion portion 200 is already well assembled (the upper connecting member 220 of the infusion portion 200, the telescopic elastic element 230 on the middle layer and the lower connecting element 240 on the bottom layer are already connected together, and the waterproof rings and the like of the silicone rubber material are also installed);

(31) step 3: during use, the infusion portion 200 shall be placed in a position of a use range to allow the user to perfuse the liquid (such as beverages, beer and the like; the infusion apparatus shall be placed in the position of a counter and the like);

(32) step 4: when the infusion portion 200 is properly placed, the infusion circulating plug 245 and the antirust connecting rod 244 are simply tightened;

(33) step 5: the installed infusion circulating plug 245 and the connecting rod 244 are tightened to the fixing position 242 of the lower connecting element 240;

(34) step 6: two infusion nozzles 222 are installed on the installation ports of the upper connecting member 220 (the infusion nozzles 222 are tightened to match the infusion nozzle sleeve 225 and the waterproof rings of the silicone rubber material);

(35) step 7: the container fixing element 210 is placed above the upper connecting member 220 to ensure that the positions of two circulating portions 212 of the container fixing element 210 are aligned with two infusion nozzles 222; the infusion nozzles 222 shall be placed on the container fixing element 210; and then the button 211 beside the container fixing element 210 is buckled with an outer wall of the upper connecting member 220; and

(36) step 8: finally, the external liquid circulating pipe 250 is connected to the lower-layer through hole 241 of the lower connecting element 240; and when the liquid is circulated, the liquid is slightly pressed from the upper portion of the infusion portion 200 to observe whether the liquid begins to flow upwards to ensure that the infusion apparatus is properly installed.

(37) Step B: Practical Application

(38) step 1: before the container portion 100 is placed above the infusion portion 200, the user shall ensure whether the infusion portion 200 is properly installed and is ready for use; see step 8 in step A;

(39) step 2: the container portion 100 is placed and fixed to the top container fixing element 210; at this moment, two pairs of corresponding circulating holes 111, 121 of the container portion 100 shall be aligned with the positions of two infusion nozzles 222; the infusion nozzles 222 shall also be communicated with the bottom of the container portion 100 from two pairs of corresponding circulating holes; the container fixing element 210 also fixes the contact of the container lower body 120 of the container;

(40) step 3: the container portion 100 is pressed with light force towards the top of the infusion portion 200; at this moment, because the telescopic elastic element 230 on the middle layer of the infusion portion 200 is pressed down, the infusion circulating plug 245 relatively rises and does not block the upper-layer through hole 221; and the liquid (such as water, beverages, beer and the like) begins to flow into the container portion 100 (the container upper body 110) from the lower-layer through hole 241 of the infusion portion 200, the middle-layer through hole 231, and the infusion nozzles 222 of the upper-layer through hole 221;

(41) step 4: when the liquid is completely filled on the bottom of the container portion 100, the operation of pressing the container portion 100 towards the infusion portion 200 can be stopped, or the container upper body 110 is rotated from an outer X direction in other manners (clockwise or counterclockwise, or otherwise the container lower body 120 is rotated); at this moment, the container fixing element 210 may be fixed and does not allow the container lower body 120 to rotate along with the container upper body 110 (or otherwise, a container fixing object 210 may be fixed and does not allow the container upper body 110 to rotate along with the container lower body 120, which is regarded as a different rotation manner); two upper protruding plugs 112 of the container upper body 110 are converted to the positions of blocking two lower circulating holes 121 of the container lower body 120; two lower protruding plugs 122 of the container lower body 120 are converted to the positions of blocking two upper circulating holes 111 of the container upper body 110 to prevent the liquid from leaking from the bottom of the container portion 100 (the container lower body 120); the infusion portion 200 is not pressed; because the originally contracted spring 232 does not bear the pressure, the telescopic elastic element 230 restores elasticity and is expanded again, while the inner infusion circulating plug 245 also returns to block the upper-layer through hole 221; and

(42) step 5: the container portion 100 is simply lifted and taken out of the container fixing element 210 of the silicone rubber; and at this moment, the liquid in the container portion 100 will not leak because all the circulating holes (two upper circulating holes 111 and two lower circulating holes 121) are blocked by all the protruding plugs (two lower protruding plugs 122 and two upper protruding plugs 112). Although residual liquid exists in positions around the infusion nozzles 222 of the infusion apparatus, the quantity of the residual liquid is small. From a perspective of sanitation, it is not recommended to apply the same container portion 100 on the infusion portion 200 again.
