In the following embodiments, the application of the funnel assembly to the coffee machine is taken as an example for description. The funnel assembly can be fixed on the body of the coffee machine, or can be detachably connected to the body of the coffee machine, which can be selected according to the needs.

[0041] In the embodiments of the present application, referring to Figures 1 to 10 A coffee machine is provided, which comprises a body 300, a funnel assembly and a control valve, the funnel assembly is connected to the body 300, and the control valve is used for controlling the opening and closing of the funnel assembly.

[0042] Referring to Figures 1 to 7 A funnel assembly is provided, which comprises a funnel 100 and a seat body 200, the funnel 100 is detachably connected to the seat body 200, that is, at least two kinds of funnels are replaceably connected in the seat body 200, which facilitates the replacement of the funnel 100 connected to the seat body 200, so that the funnel assembly can be installed with funnels 100 of different structural shapes.

[0043] Referring to Figure 1 As shown in the figure, a through cavity 111 is formed in the funnel 100. It can be understood that the funnel 100 has an inlet 112 and an outlet 113 in communication with the cavity 111, so that the fluid flows along the inlet 112, the cavity 111 and the outlet 113.

[0044] A control valve is located at the outlet end of the cavity 111, and is used to open and close the outlet end of the cavity 111.

[0045] It can be understood that the funnel 100 includes at least one of a V-shaped funnel, a conical funnel, and a trapezoidal funnel. The conical funnel can include a circular conical funnel or a frustoconical funnel. The V-shaped and trapezoidal funnel of the funnel 100 can be understood as the shape of the longitudinal section (which can be the longitudinal section of the inner wall surface or the outer wall surface) thereof, and the conical funnel of the funnel 100 can be understood as the spatial three-dimensional shape thereof.

[0046] Reference is made to Figure 10 It is shown that a coffee machine is provided with another funnel 100, and the shape of the cavity 111 of the funnel 100 is different from Figure 8 the shape of the funnel 100 shown in the figure. Figure 10 In the funnel 100 shown in the figure, the inner wall of the funnel 100 is curved, Figure 8 In the funnel 100 shown in the figure, the inner wall of the funnel 100 includes a curved surface and a flat surface.

[0047] Reference is made to Figure 1 and Figure 2 It is shown that the outer wall of the funnel 100 is provided with at least one of a groove 121 and an elastic clamping portion 210; the inner wall of the seat body 200 is provided with an elastic clamping portion 210 matched with the groove 121, and / or a groove 121 matched with the elastic clamping portion 210. The funnel 100 is adapted to switch between an installed position and a disassembled position. In the installed position, the funnel 100 is inserted into the seat body 200, and the elastic clamping portion 210 is limited in the groove 121. In the disassembled position, the funnel 100 is separated from the seat body 200, and the elastic clamping portion 210 is separated from the groove 121. Figure 1 The funnel 100 in the installed position is shown in the figure. The disassembled position is not shown in the figure.

[0048] It can be understood that, with reference to Figure 1 and Figure 2 It is shown that when the funnel 100 has the groove 121, the seat body 200 is provided with the elastic clamping portion 210, and the connection between the funnel 100 and the seat body 200 is achieved by one or more sets of the groove 121 and the elastic clamping portion 210. When the funnel 100 is provided with the elastic clamping portion, the seat body 200 has the groove (not shown in the figure), and the connection between the funnel 100 and the seat body 200 is achieved by one or more sets of the groove 121 and the elastic clamping portion 210. When the funnel 100 is provided with the groove and the elastic clamping portion, the seat body 200 is provided with the elastic clamping portion matched with the groove and the groove matched with the elastic clamping portion (not shown in the figure), and the connection between the funnel 100 and the seat body 200 is achieved by two or more sets of the groove 121 and the elastic clamping portion 210.

[0049] The seat body 200 is detachably connected with the funnel 100, so that the seat body 200 can replace different types of funnels 100. During the installation of the funnel 100 to the seat body 200, the elastic clamping portion 210 needs to be pressed and overcome the elastic force of the elastic clamping portion 210 (the elastic force of the elastic clamping portion 210 can be understood as the locking force of the seat body 200 and the funnel 100), until the elastic clamping portion 210 is limited in the groove body 121, to realize the switching from the disassembly position to the installation position, that is, to realize the installation of the funnel 100 and the seat body 200. Similarly, the switching from the installation position to the disassembly position also needs to press the elastic clamping portion 210 and overcome the elastic force of the elastic clamping portion 210. By using the elastic deformation of the elastic clamping portion 210, the funnel 100 can be limited in the seat body 200, and the elastic deformation of the elastic clamping portion 210 can prevent the funnel 100 from being separated from the seat body 200, thereby ensuring the installation stability of the funnel 100 and the seat body 200.

[0050] The funnel assembly of the embodiment of the utility model, utilize the elastic force of action of elastic clamping portion 210, make funnel 100 fixed in seat body 200, still convenient funnel 100 is disassembled in seat body 200, to replace the funnel 100 of different structure form. Different structure's funnel 100, can be understood as, through the cooperation of elastic clamping portion 210 and groove body 121, realize the connection of funnel 100 and seat body 200, but the structure of other parts of funnel 100 can not be same, such as the shape of cavity 111 in funnel 100 is different, the contour shape of the outer wall of funnel 100 is different, the material of funnel 100 is different, etc.

[0051] It should be noted that the number of elastic clamping portions 210 and the number of groove bodies 121 can be the same. Of course, the number of elastic clamping portions 210 can be less than or equal to the number of groove bodies 121, and the cooperation relationship of the elastic clamping portions 210 and the groove bodies 121 is more flexible.

[0052] The cavity 111 in the funnel 100 can be understood as the cross-sectional area of the cavity 111 gradually decreases in the direction from the inlet 112 to the outlet 113, and the wall surface surrounding the cavity 111 can include one or both of a curved surface and a plane. Figure 3 and Figure 4 As shown in the funnel 100, the inner wall surface of the cavity 111 includes a curved surface and a plane connected to the curved surface, and the cavity 111 can be understood as an irregular cavity. Figure 5 and Figure 6 As shown in the funnel 100, the inner wall of the cavity 111 includes a curved surface, and the cavity 111 can be understood as a conical cavity.

[0053] It can be understood that, as shown in Figure 1As shown, the funnel 100 comprises a connecting portion 110 and a mounting portion 120 connected to the outer wall of the connecting portion 110, the connecting portion 110 is formed with a through cavity 111, and the outer wall of the mounting portion 120 is provided with at least one of a groove 121 and an elastic clamping portion 210. The connecting portion 110 is used to form an inlet 112, a cavity 111 and an outlet 113, and the mounting portion 120 is used to provide one or both of the groove 121 and the elastic clamping portion 210, and the connecting portion 110 and the mounting portion 120 play different roles.

[0054] It can be understood that the connecting portion 110 is formed with the above-mentioned cavity 111. In some cases, the shape of the cavity 111 formed in the connecting portion 110 can include a conical shape, a V shape, a frustum shape, etc.

[0055] The connecting portion 110 and the mounting portion 120 can be integrally formed, but are not limited to this, and the connecting portion 110 and the mounting portion 120 can also be detachably connected. The materials of the connecting portion 110 and the mounting portion 120 can be the same or different, and can be set as needed. The mounting portion 120 can be formed as a closed-loop integral structure around the connecting portion 110, or the mounting portion 120 can not be formed as a closed loop, for example, the mounting portion 120 can include a sheet structure arranged on the connecting portion 110, and the mounting portion 120 can include a plurality of sheet structures distributed at intervals around the connecting portion 110.

[0056] In some cases, referring to Figure 3 and Figure 5 As shown, the mounting portion 120 is connected to the lower part of the connecting portion 110, so that the elastic clamping portion 210 and the groove 121 can be clamped at the lower part, reducing the disassembly resistance, facilitating disassembly, and also reducing the influence on the shape of the funnel 100. In some cases, the bottom surface of the mounting portion 120 can also serve as a support for the funnel 100, facilitating the placement of the funnel 100 after disassembly. Of course, the mounting portion 120 is not limited to being mounted on the lower part of the connecting portion 110, and can be adjusted as needed.

[0057] It can be understood that a plurality of grooves 121 are arranged around the mounting portion 120, and the plurality of grooves 121 can cooperate with the plurality of elastic clamping portions 210 of the seat body 200 to limit the funnel 100 and the seat body 200 at multiple positions, ensuring the connection stability of the funnel 100 and the seat body 200.

[0058] A plurality of elastic clamping portions (not shown in the figure) are arranged around the mounting portion 120, and the plurality of elastic clamping portions 210 can cooperate with the plurality of grooves of the seat body 200 to limit the funnel 100 and the seat body 200 at multiple positions, ensuring the connection stability of the funnel 100 and the seat body 200.

[0059] Of course, the installation part 120 is circumferentially provided with a plurality of groove bodies and a plurality of elastic clamping parts (not shown in the figure), and the seat body 200 is correspondingly provided with a plurality of elastic clamping parts and a plurality of groove bodies, so that the funnel 100 and the seat body 200 are limited at multiple positions.

[0060] In some cases, the funnel 100 and the seat body 200 are matched by three groups of elastic clamping parts 210 and groove bodies 121, and the adjacent two groups of elastic clamping parts 210 and groove bodies 121 can form an included angle of 120°, so as to ensure that the funnel 100 and the seat body 200 are uniformly stressed.

[0061] It can be understood that the elastic force of the elastic clamping part 210 is greater than or equal to 3N and less than or equal to 20N, so as to ensure that the funnel 100 can be stably arranged in the seat body 200. The elastic force of the elastic clamping part 210 can be set to 5N, 8N, 10N, 12N, 15N, etc.

[0062] The elastic force of the elastic clamping part 210 needs to ensure that when the funnel 100 is subjected to the thrust of the valve body 140 opening the outlet 113, the funnel 100 is still stably arranged in the seat body 200, so as to avoid that the funnel 100 is pulled out of the seat body 200 by the action force of the valve body 140, effectively ensuring that the valve body 140 is fixed and has no virtual position, so as to achieve precise control linkage of the valve body 140 and the liquid outlet 312 of the body 300 of the coffee machine.

[0063] The direction of the elastic force of the elastic clamping part 210 can be understood as a direction perpendicular to the dismounting direction of the funnel 100. Here, the perpendicularity is not limited to strict perpendicularity, but can have a floating range within a predetermined range, for example, a floating range of less than or equal to 10°. The elastic clamping part 210 can be provided with elastic force by an elastic material, a spring, etc., but is not limited thereto.

[0064] It can be understood that the elastic clamping part 210 can be a component fixed to the funnel 100 or the seat body 200, or can be a component detachably connected to the funnel 100 or the seat body 200. The mounting mode of the elastic clamping part 210 is not limited.

[0065] In some cases, referring to Figure 1 and Figure 2 , taken as an example that the elastic clamping part 210 is detachably mounted on the seat body 200, the elastic clamping part 210 includes a plug-in part 211, the plug-in part 211 is inserted into the groove 221 of the seat body 200, and the elastic clamping part 210 is detachably connected to the seat body 200 by the plug-in mode. The mounting mode of the elastic clamping part 210 is simple, and it is also convenient to replace the elastic clamping part 210. At this time, the elastic clamping part 210 can be understood as an independent part independent of the seat body 200, and can be detached and replaced.

[0066] The recess 221 of the seat body 200 is provided with a protruding part (not shown in the figure), and the insertion part 211 is provided with an insertion groove. The protruding part is inserted into the insertion groove, and the protruding part and the insertion groove are matched to increase the contact area of the seat body 200 and the elastic clamping part 210, increase the resistance of the elastic clamping part 210 from the seat body 200, and improve the connection stability of the seat body 200 and the elastic clamping part 210. The shape of the insertion part 211 can be, but is not limited to, a cuboid, a cube, a cylinder, a pyramid, etc.

[0067] In some cases, the elastic clamping part 210 is installed in the seat body 200 in an elastic shape state, and the surface of the elastic clamping part 210 and the surface of the recess 221 of the seat body 200 form a pressing force to ensure the installation stability of the elastic clamping part 210 in the seat body 200.

[0068] Of course, the elastic clamping part 210 can also be connected to the funnel 100 by insertion. The specific installation method can refer to the connection method of the elastic clamping part 210 and the seat body 200, which will not be repeated here.

[0069] It can be understood that the elastic clamping part 210 also includes a limiting part 212, which is suitable for being limited in the groove body 121. The limiting part 212 has an outward convex arc surface 2121, and the edge of the arc surface 2121 is connected to the insertion part 211. During switching between the installation position and the disassembly position, the arc surface 2121 contacts the outer wall of the funnel 100, the contact area is small, the contact friction between the elastic clamping part 210 and the outer wall of the funnel 100 can be reduced, and the disassembly and assembly of the funnel 100 are facilitated.

[0070] The limiting part 212 has an outward convex arc surface 2121. It can be understood that from the edge of the arc surface 2121 to the inside of the arc surface 2121, the arc surface 2121 protrudes away from the insertion part 211. The inside of the arc surface 2121 can be understood as the position away from the edge. The inside of the arc surface 2121 can be the position with the maximum protruding distance relative to the insertion part 211. The arc surface 2121 can be a spherical surface, an ellipsoidal surface, etc., and the shape of the arc surface 2121 is not limited. Correspondingly, the shape of the limiting part 212 can be, but is not limited to, a semispherical ball, a semielliptical ball.

[0071] The limiting part 212 and the insertion part 211 can be integrally formed or detachably connected, which can be set as needed.

[0072] It can be understood that the funnel 100 is provided with a handle 150. When switching different funnels 100, the user can pull up the handle 150, the outer wall of the funnel 100 overcomes the elastic force of the elastic clamping part 210, the elastic clamping part 210 is squeezed and shrunk, and the funnel 100 can be pulled out of the seat body 200. In some cases, the elastic clamping part 210 can include, but is not limited to, a rubber ball, a rectangular elastic block, a trapezoidal elastic block, a spring, etc.

[0073] It can be understood that, with reference to Figure 1 and Figure 7 As shown, the outlet end of the funnel 100 is connected with a valve body 140 and a sealing member 130, the sealing member 130 is switched between a sealing position and an unsealing position, in the sealing position, the sealing member 130 is sealed between the funnel 100 and the valve body 140, in the unsealing position, the sealing member 130 unseals the funnel 100 and the valve body 140, the notch of the valve body 140 is communicated with the outlet 113 of the funnel 100. The sealing member 130 and the valve body 140 cooperate, which can be understood as playing a role of plugging the outlet 113, that is, playing a role of leak stopping.

[0074] In the process of switching between the sealing position and the unsealing position, the sealing member 130 can be fixed with the funnel 100, or the sealing member 130 is fixed with the valve body 140, the position of the sealing member 130 can be selected as needed. With reference to Figure 1 and Figure 2 As shown, the sealing member 130 is fixed to the valve body 140, and the sealing member 130 moves synchronously with the valve body 140 when the valve body 140 moves relative to the funnel 100.

[0075] With reference to Figure 1 and Figure 7 As shown, the valve body 140 includes a valve core 141 and a spring 142, the spring 142 is limited between the valve core 141 and the funnel 100. In the process from the sealing position to the unsealing position, the valve core 141 is subjected to an external force, the valve core 141 moves relative to the funnel 100, the sealing member 130 unseals the sealing function, and also drives the spring 142 to elastically deform, so that the notch 1411 of the valve core 141 is communicated with the outlet 113 of the funnel 100 to form a flow channel, the funnel 100 is unsealed, so that the liquid in the funnel 100 can flow out through the outlet 113 of the funnel 100 and the notch 1411 of the valve core 141, and the funnel 100 is opened. In the process from the unsealing position to the sealing position, the external force of the valve core 141 is removed, the valve core 141 is reset under the driving of the restoring force of the spring 142, so that the sealing member 130 is sealed between the funnel 100 and the valve core 141, the flow channel between the outlet 113 of the funnel 100 and the opening of the valve core 141 is disconnected, the liquid cannot flow out from the outlet 113 of the funnel 100, and the valve body 140 and the sealing member 130 play a role of leak stopping. The valve body 140 can be switched from the sealing position to the unsealing position by using an external force, and can be switched from the unsealing position to the sealing position by using the restoring force of the spring 142 in the valve body 140, and the control of the valve body 140 is simple.

[0076] In some cases, the flow passage formed between the valve core 141 and the funnel 100 gradually increases or gradually decreases in flow area in the direction from the sealed position to the unsealed position, so that the flow rate and the flow rate can be adjusted by adjusting the position of the valve core 141, that is, the opening degree between the valve body 140 and the funnel 100 can be controlled, so as to achieve the effect of controlling different release flow rates.

[0077] It can also be understood that, as shown in Figure 1 It can also be understood that, as shown in

[0078] In some cases, the trigger 231 can be a magnet, and the detection piece 320 can be a magnetic induction sensor. When the seat body 200 is connected with the magnet, the funnel assembly does not need to be powered, and the structure of the funnel assembly can be simplified. Of course, the detection piece 320 can be a proximity switch, and the trigger 231 can also be a structure suitable for the proximity switch, such as a protrusion, a light-emitting piece, etc. The cooperation form of the trigger 231 and the detection piece 320 is various, and can be selected according to needs.

[0079] It can be understood that the seat body 200 includes a seat body 220 and a mounting piece 230 detachably connected to the seat body 220, and the seat body 220 is detachably connected to the funnel 100. The mounting piece 230 is connected to one of the trigger 231 and the detection piece 320, so that the trigger 231 or the detection piece 320 can be detachably connected to the seat body 200, facilitating disassembly and replacement. The mounting piece 230 can be connected to the seat body 220 by a fastener 232, a clamping connection, etc. As shown in Figure 1 It can be understood that the seat body 200 includes a handle, facilitating disassembly and assembly of the seat body 200 from the body of the coffee machine.

[0080] It can be understood that the seat body 200 includes a handle, facilitating disassembly and assembly of the seat body 200 from the body of the coffee machine.

[0081] The funnel assembly in the above embodiment, the funnel assembly is detachably connected with the funnel 100 in the seat body 200, different types of funnels 100 can be replaced, the bottom of the funnel 100 is connected with the valve body 140, the opening of the outlet 113 of the funnel 100 can be adjusted through the valve body 140, when the funnel assembly is applied to the coffee machine, the funnel assembly has controllable brewing, thereby enriching the design of coffee flavor.

[0082] It can be understood that, referring to Figure 8 and Figure 9 , the control valve includes a valve body 140 and a sealing member 130, that is, the outlet end of the funnel 100 is connected with the valve body 140 and the sealing member 130, the machine body 300 is connected with a driving device 310, the driving device 310 is used to provide driving force to the valve body 140, so that the sealing member 130 is switched between the sealing position and the unsealing position. The driving device 310 is installed on the machine body 300, which can simplify the structure of the funnel assembly, and the structural stability of the driving device 310 is also better.

[0083] The driving device 310 includes a driving component 311 and a liquid outlet member 312, the driving component 311 has a first inclined surface 3114, the liquid outlet member 312 has a second inclined surface 3121, the first inclined surface 3114 and the second inclined surface 3121 are parallel along a first direction, the driving component 311 is used to provide a moving driving force along a second direction, based on the first inclined surface 3114 and the second inclined surface 3121 contact and cooperate, to drive the liquid outlet member 312 to move along a third direction, the liquid outlet member 312 drives the valve body 140 to move, so that the sealing member 130 is switched between the sealing position and the unsealing position, the second direction is perpendicular to the third direction, and the first direction forms an acute angle with the second direction.

[0084] Referring to Figure 8 and Figure 9 , the second direction can be understood as a horizontal direction, the third direction can be understood as a vertical direction, and the first direction can be understood as a direction forming an angle of 10°, 30°, 45°, 60°, etc. with the horizontal direction. The driving component 311 provides horizontal driving force, which is converted into vertical driving force through the contact and cooperation of the first inclined surface 3114 and the second inclined surface 3121, and then drives the liquid outlet member 312 to move vertically. The liquid outlet member 312 moves and transmits the moving power to the valve body 140, and the valve body 140 moves vertically to switch the sealing member 130 from the sealing position to the unsealing position.

[0085] The driving component 311 comprises a motor 3111, a screw rod 3112 and a nut 3113. The motor 3111 drives the screw rod 3112 to rotate, and the rotating power of the screw rod 3112 is converted into the moving power of the nut 3113.

The liquid outlet 312 has a water outlet nozzle which is in communication with the notch 1411 of the valve body 140. When the sealing member 130 is in the sealing position and the outlet 113 of the funnel 100 is closed, the shower 400 at the top of the coffee machine continuously discharges water to soak the coffee powder. Since the valve body 140 is in a closed state under the action of the spring 142 therein, the coffee is fully soaked. After the coffee is soaked, the motor 3111 of the driving component 311 is started, and the liquid outlet 312 is driven to move vertically by the nut 3113, so that the valve body 140 moves vertically until the sealing member 130 removes the closing function of the outlet 113 of the funnel 100. The outlet 113 of the funnel 100 is opened, and the coffee can fall into the container 500 (such as a coffee pot or a coffee cup) below the outlet 113 of the funnel 100, and the user can get the coffee which is fully soaked.

[0086] In some cases, according to the user's selection of different coffee flavors, the screw rod 3112 of the motor 3111 can realize different linear stroke control, drive the nut 3113 to fit the liquid outlet 312, realize the upward movement of the liquid outlet 312, thereby realizing the control of the height of the valve body 140, adjusting the opening degree of the valve body 140, and allowing the coffee in the coffee basket to flow into the coffee pot below at different release speeds. Conversely, the motor 3111 can also move in reverse to return to the starting position. The motor 3111 can be provided with a position sensor such as a Hall sensor, etc., to improve reliability.
