DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0028] A mocca kettle with a filtering structure, such as Figure 1 and Figure 2, including the upper pot 1, the lower pot 2 and the funnel arranged in the lower pot 2, the upper pot 1 is hollow cylindrical, one side of the outer wall can be provided with a handle, the upper pot 1 and the lower pot 2 are fixedly connected through the locking ring 11, the upper pot 1 is provided with a water distributor assembly, the water distributor assembly comprises a hollow water distributor pipe 12, a groove 121 is arranged at the upper end of the water distributor pipe 12, a pot cover 122 is arranged on the upper pot 1, and a filter assembly is arranged on the water distributor pipe 12 and used for filtering coffee liquid flowing out of the groove 121. The structure of the upper pot 1, the water distributor assembly and the lower pot 2 and the structure of the locking ring 11 can be the structure of the upper pot 1, the water distributor assembly and the lower pot 2 and the structure of the locking ring 11 in the mocha pot disclosed in the Chinese patent with the publication number CN209733529U, and the main invention point of the application is that the filter assembly is arranged on the water distributor pipe 12 and used for filtering coffee liquid flowing out of the groove 121 in the water distributor pipe 12, so that how the coffee liquid flows out of the groove 121 in the water distributor pipe 12 can refer to the prior art and is not limited to the structure disclosed in the publication number CN209733529U, as long as the mocha pot has the water distributor pipe 12 and the groove 121 arranged on the water distributor pipe 12, that is, the outlet of the coffee liquid, the filter assembly can be installed.

[0029] As Figure 1 And Figure 2 , water is added into the lower pot 2, then the funnel filled with coffee powder is arranged in the lower pot 2, then the upper pot 1 and the lower pot 2 are connected through the locking ring 11, the whole mocha pot is taken to the heating device for heating, the steam boiled in the lower pot 2 passes through the funnel, mixes with the coffee powder and is introduced into the water distributor pipe 12, and then flows into the upper pot 1 from the groove 121 of the water distributor pipe 12 to complete coffee making, when the coffee liquid flows out of the groove 121 of the water distributor pipe 12, the filter assembly arranged on the water distributor pipe 12 filters the coffee liquid flowing out of the groove 121, reduces the existence of residues in the coffee liquid, and further improves the taste of coffee.

[0030] As Figure 2 And Figure 3, the filter assembly comprises a first moving ring 13 slidably connected to the outer wall of the water diversion pipe 12, and a second moving ring 131 slidably connected to the inner wall of the upper kettle 1. The first moving ring 13 and the second moving ring 131 both vertically slide and cannot rotate. At this time, in order to limit the self-rotation of the first moving ring 13 and the second moving ring 131, a plurality of guide grooves can be formed on the inner wall of the upper kettle 1. The outer wall of the second moving ring 131 is provided with guide blocks that slide in the guide grooves. The guide grooves are distributed along the moving direction of the second moving ring 131. The outer wall of the second moving ring 131 slides with the inner wall of the upper kettle 1. Because of the arrangement of the second moving ring 131, the space inside the upper kettle 1 is distributed in a cylindrical hollow. The first moving ring 13 and the second moving ring 131 are connected by a filter cloth 132. The arrangement of the filter cloth 132 facilitates the filtration of coffee liquid flowing out of the groove 121. The first moving ring 13 and the second moving ring 131 are connected by a plurality of spaced connecting rods 133, so that the first moving ring 13 and the second moving ring 131 can move up and down together. The outer wall of the lower end of the upper kettle 1 is communicated with a water outlet pipe 14. The position where the water outlet pipe 14 communicates with the upper kettle 1 is lower than the height of the second moving ring 131, which facilitates the pouring of the filtered coffee liquid from the water outlet pipe 14. The water outlet pipe 14 extends upwardly and bends away from the outer wall of the upper kettle 1. The lid 122 is provided with a driving member for driving the first moving ring 13 to move up and down. At this time, the lid 122 closes the kettle opening of the upper kettle 1. The upper kettle 1 can be provided with a support ring for the lid 122 to be placed in the periphery of the kettle opening. When the lid 122 covers the kettle opening of the upper kettle 1, it is supported by the support ring and closes the kettle opening of the upper kettle 1. In addition, the lid 122 can be tightly connected with the kettle opening of the upper kettle 1. A plurality of clamping blocks can also be provided on the side of the lid 122 facing the support ring. When the clamping blocks come into contact with the support ring, they are embedded in the upper end surface of the support ring, thereby limiting the rotation of the lid 122.

[0031] As Figure 2 and Figure 3 When the coffee liquid flows out of the groove 121, the driving member drives the first moving ring 13 to gradually move upwardly. At this time, the first moving ring 13 drives the second moving ring 131 to also move upwardly through the connecting rod 133. The filter cloth 132 filters the coffee liquid during the moving process. The coffee liquid below the filter cloth 132 is filtered coffee liquid, and the coffee liquid above the filter cloth 132 is unfiltered coffee liquid. As the amount of filtered coffee liquid below the filter cloth 132 gradually increases, the filter cloth 132 gradually moves upwardly with the first moving ring 13 until it moves below the groove 121. At this time, the coffee liquid is below the filter cloth 132, which facilitates the pouring of the filtered coffee liquid from the water outlet pipe 14. After the water outlet pipe 14 pours out the coffee liquid in the upper kettle 1, the driving member drives the first moving ring 13 to move downwardly, thereby facilitating the filtration in the next cycle.

[0032] As Figure 2 and Figure 3Each connecting rod 133 is located below the filter cloth 132 and provides support for the filter cloth 132. The purpose of this design is that after the filter cloth 132 bears the coffee liquid, on one hand, the coffee liquid is filtered, and on the other hand, the filter cloth 132 is deformed downward due to the presence of the coffee liquid, and the connecting rod 133 is arranged to facilitate the support of the filter cloth 132.

[0033] As Figure 2 and Figure 3 The driving member includes a rotating drum 15 rotatably connected to the lid 122, the upper end of the rotating drum 15 extends out of the upper end surface of the lid 122, and the lower end is located in the upper kettle 1. The upper end surface of the first moving ring 13 is provided with a filter drum 151 sleeved on the outer wall of the water distribution pipe 12. The filter drum 151 is coaxially arranged with the water distribution pipe 12 and has a gap between the outer wall of the water distribution pipe 12. A plurality of outflow holes 152 for the coffee liquid to flow out are formed in the drum wall of the filter drum 151. The upper end of the filter drum 151 penetrates into the lower end drum wall of the rotating drum 15, and the outer wall of the rotating drum 15 located in the upper kettle 1 is provided with a helical driving groove 153 distributed along the outer wall of the rotating drum 15. The extension range of the driving groove 153 along the outer wall of the rotating drum 15 can be within the range of 0-180° of the rotating drum 15, or at most 300°, that is, when the higher point and the lower point of the driving groove 153 are projected onto the same horizontal plane, the included angle between the two points and the center line of the rotating drum 15 is less than 300°. The outer wall of the filter drum 151 located in the rotating drum 15 is threadedly connected with a driving column 154 entering the driving groove 153. The driving column 154 is in sliding connection with the driving groove 153, and one end of the driving column 154 extends out of the driving groove 153. At this time, it is convenient to install the driving column 154 through the driving groove 153.

[0034] As Figure 2 and Figure 3When the first moving ring 13 needs to be driven to move upward along the water diversion pipe 12, the user rotates the upper end of the rotating drum 15, so that the rotating drum 15 drives the driving column 154 to slide in the driving groove 153. During the movement of the driving column 154 from the lower end to the upper end of the driving groove 153, the filter cylinder 151 gradually moves into the rotating drum 15 along with the driving column 154, so that the filter cylinder 151 drives the first moving ring 13 to move upward as well. When the driving column 154 is located at the upper end of the driving groove 153, the filter cloth 132 is located below the recess 121 and the filter cylinder 151 has not completely entered the rotating drum 15, so that the filter cylinder 151 facilitates the outflow of the coffee liquid in the recess 121.

[0035] As Figure 2 And Figure 3 When the driving column 154 is located at the lower end of the driving groove 153, the inner wall of the upper kettle 1 is provided with a blocking block 155 above the position where the water outlet pipe 14 communicates with the upper kettle 1 and abuts against the lower end surface of the second moving ring 131. The purpose of this design is to limit the movement of the second moving ring 131 below the position where the water outlet pipe 14 communicates with the upper kettle 1, so that the coffee liquid flowing out of the water outlet pipe 14 is always filtered.

[0036] As Figure 2 And Figure 4 The outer wall of the lower end of the rotating drum 15 is circumferentially detachably connected with a plurality of L-shaped stirring rods 16. The horizontal part of the stirring rod 16 is detachably connected with the outer wall of the rotating drum 15, the vertical part extends downward, and the lower end of the vertical part of the stirring rod 16 is provided with a conical stirring cover 161. The smaller end of the conical stirring cover 161 is connected with the vertical part of the stirring rod 16, and the larger end has an opening and faces the filter cloth 132. There is a gap between the lower end surface of the stirring cover 161 and the filter cloth 132. When the rotating drum 15 rotates, the stirring cover 161 rotates, and the rotating stirring cover 161 disturbs the coffee liquid on the upper layer of the filter cloth 132, thereby facilitating the filtration of the coffee liquid. When the filter cloth 132 moves to the highest point along with the first moving ring 13, there is a gap between the lower end surface of the stirring cover 161 and the filter cloth 132, i.e., the lower end surface of the stirring cover 161 contacts the filter cloth 132. At this time, the rotating rotating drum 15 drives the stirring cover 161 to push the filtered residue on the filter cloth 132, so that the coffee liquid remaining on the upper layer of the filter cloth 132 is filtered by the filter cloth 132.

[0037] As Figure 2 And Figure 5 The conical surface of the stirring cover 161 is spliced by eight triangular first plates 162, each first plate 162 is an isosceles triangle, and the adjacent two first plates 162 are connected with each other, the bottom of each first plate 162 is connected with a second plate 163, the second plate 163 is an equilateral triangle, the adjacent two second plates 163 are connected through a third plate 164, the third plate 164 is an equilateral triangle with the same length as the second plate 163, the adjacent two first plates 162 and the first plate 162 and the second plate 163 and the second plate 163 and the third plate 164 are connected through connecting pieces, and the two first plates 162 are close to each other on one side or the first plate 162 and the second plate 163 are close to each other on one side or the second plate 163 and the third plate 164 are close to each other on one side, and a plurality of connecting holes 165 are formed in the close side; the first plate 162 is provided to make the outer wall of the stirring cover 161 present a plurality of edges, so as to facilitate stirring of the coffee liquid and reduce the resistance of the coffee liquid moving in the coffee liquid; in addition, the second plate 163 and the third plate 164 are provided to increase the number of edges of the stirring cover 161, so as to facilitate stirring of the coffee liquid, and the third plate 164 and the second plate 163 are provided to make the lower end of the stirring cover 161 present a closed shape, and the connecting holes 165 are provided to facilitate the coffee liquid flowing into the space formed by the first plate 162, the second plate 163 and the third plate 164, thereby facilitating stirring of the coffee liquid.

[0038] As Figure 2 And Figure 5 The connecting piece includes a plurality of fixed plates 166 which are spaced apart and arranged between the two first plate 162 waists or between the first plate 162 and the second plate 163 or between the second plate 163 and the third plate 164, and the two ends of the fixed plate 166 are respectively welded with the two first plate 162 waists or the side edges between the first plate 162 and the second plate 163 or the side edges between the second plate 163 and the third plate 164. At this time, the fixed plate 166 is spaced apart and arranged between the two first plates 162 or between the side edges of the first plate 162 and the second plate 163 or between the side edges of the second plate 163 and the third plate 164, so that there is a gap between the two first plates 162, the first plate 162 and the second plate 163, and the second plate 163 and the third plate 164, facilitating the flow of the coffee liquid in the gap, thereby increasing the stirring of the coffee liquid, at this time, after increasing the stirring of the coffee liquid, it is convenient to increase the flow speed of the coffee liquid on the upper layer of the filter cloth 132, at this time, the residue mixed in the coffee liquid also flows in the coffee liquid or on the filter cloth 132 along with the flow of the coffee liquid, facilitating the flowing coffee liquid to be filtered from the filter cloth 132 to the lower layer of the filter cloth 132.

[0039] As Figure 2 And Figure 4, in order to install the stirring rod 16 according to the demand, the outer wall of the lower end of the drum 15 is provided with an insertion hole 167 for the horizontal part of the stirring rod 16 to be inserted, the length direction of the insertion hole 167 is along the axis length direction of the drum 15, and the horizontal part of the stirring rod 16 is provided with an insertion plate 168 matched with the insertion hole 167, the upper end of the insertion plate 168 is located at the upper end of the horizontal part of the stirring rod 16, and the outer wall of the drum 15 is threadedly connected with a locking cylinder 169, which is rotated to the aperture of the insertion hole 167.

[0040] As Figure 2 and Figure 4 When it is needed to install each stirring rod 16, the insertion plate 168 on each stirring rod 16 is installed into the insertion hole 167, and then the locking cylinder 169 is rotated so that the locking cylinder 169 moves to the aperture of the insertion hole 167 and presses the upper end of the insertion plate 168 in the insertion hole 167, at this time, the lower end of the locking cylinder 169 is in contact with the horizontal part of the stirring rod 16, thereby limiting the position of each stirring rod 16 and fixing the stirring rod 16 on the drum 15, when it is needed to be disassembled, only the locking cylinder 169 is rotated away from the aperture of the insertion hole 167, and then the insertion plate 168 is taken out of the insertion hole 167, which is ingenious.

[0041] As Figure 2 The drum 15 is provided with a hand wheel 17 on the outer wall of the end extending out of the upper end surface of the cover 122, and when the driving column 154 moves to the higher end of the driving groove 153, the hand wheel 17 is threadedly connected with a positioning rod 171, and the upper end surface of the cover 122 is provided with an entry hole 172 for one end of the positioning rod 171 to enter. When the driving column 154 moves to the higher end of the driving groove 153, the user will not be able to continue to rotate the drum 15, at this time, the positioning rod 171 is rotated into the entry hole 172, which limits the rotation of the drum 15, thereby facilitating the fixing of the filter cloth 132 at the highest position and facilitating the pouring of the coffee liquid in the outlet pipe 14.

[0042] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application belong to the scope of the claims of the present application and their equivalent technologies, the present application also intends to include these modifications and variations.
