Description

Technical Field

[0001] This utility model relates to the field of foaming device technology, specifically to an air-inlet foaming device, and also discloses a beverage machine. Background Technology

[0002] As people's living standards improve, the quality of life has also been given more meaning. Adding fine bubbles to beverages can greatly enhance their taste and appearance, such as in Italian coffee with milk foam. Currently, most foamers on the market use a honeycomb structure as the foaming core, resulting in a relatively large volume. Furthermore, due to the large pore size of the honeycomb, the created bubbles are too large, making it difficult for them to remain stable and long-lasting.

[0003] Chinese patent CN201958642U discloses a coffee frying device, including a coffee box. The coffee box has a nozzle body at the center of its bottom. The nozzle body has a channel axially arranged in the center. One end of the channel near the bottom of the coffee box has a single-hole metal filter. The other end of the channel has a baffle. A plurality of small holes are provided between the baffle and the side wall of the channel. The side wall of the channel between the metal filter and the baffle has a through hole that communicates with the outside.

[0004] In the aforementioned prior art, coffee liquid is sprayed through a single hole in a metal filter, impacting a bottom baffle to disperse the liquid. Through-holes in the channel sidewall draw in air, which mixes with the coffee liquid to create foam. The drawback is that the mixing time between the coffee liquid and air within the channel is too short, and the air intake is limited by external air pressure, resulting in poor foaming. Therefore, the existing technology requires further improvement and development. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing an air-inlet foaming device with a reasonable structure and good foaming effect.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] This utility model discloses an air-intake foaming device, comprising a foaming body with an inlet and an outlet; a mixing chamber connected to the inlet and outlet; an air inlet on the foaming body, the air intake direction of which is tangential to the side wall of the mixing chamber; and a foaming chip with several filter holes inside the mixing chamber. Gas enters the mixing chamber through the air inlet, and water enters the mixing chamber through the inlet. The air intake direction of the air inlet is tangential to the side wall of the mixing chamber. The gas drives the water to rotate at high speed within the mixing chamber, forming a vortex, which prolongs the flow path of the water within the mixing chamber. Furthermore, the vortex causes the water and gas to tumble within the mixing chamber, generating more bubbles.

[0008] Furthermore, the foaming chip restricts the flow of water in the mixing chamber and breaks up the bubbles in the water through several filter holes, turning large bubbles into small bubbles, thereby forming a rich and dense bubble water column at the water outlet.

[0009] According to the above scheme, the mixing chamber is vertically opened at the upper part of the foam body, the upper end of the mixing chamber is connected to the water inlet, and the foaming chip is set at the lower end of the mixing chamber; the side wall of the foam body is provided with an air inlet pipe, and the air inlet pipe is connected to the mixing chamber through an air inlet hole.

[0010] The mixing chamber is a circular hole, and the inlet, mixing chamber and outlet are arranged in sequence from top to bottom. Water enters the mixing chamber on the foam body vertically.

[0011] The air intake pipe is used to connect to the air source. The air intake pipe is set in a horizontal direction and connects to the mixing chamber through the air intake hole.

[0012] The air intake direction of the air inlet is tangent to the side wall of the mixing chamber. Specifically, in a horizontal cross-section, one of the contour edges of the air inlet is tangent to the outer edge of the mixing chamber, so that the air inlet and the mixing chamber form a vortex structure. Gas enters the mixing chamber horizontally from the air inlet, causing the gas to drive the water to rotate at high speed within the mixing chamber, forming a vortex.

[0013] Furthermore, as the water rotates in a vortex, the water at the edge of the mixing chamber rolls towards the center, causing the water and gas to mix continuously to form more bubbles.

[0014] Furthermore, the foaming chip is located at the lower end of the mixing chamber. The foaming chip restricts the flow of water in the mixing chamber and disperses the bubbles through several filter holes, turning large bubbles into small bubbles, thereby forming a rich and dense bubble water column at the water outlet.

[0015] According to the above scheme, the mixing chamber is a conical hole with a larger upper part and a smaller lower part. The angle between the side wall of the mixing chamber and the horizontal plane is C, where 45°≤C≤89°. The mixing chamber is a conical hole structure. The gas drives the water to rotate in the mixing chamber to generate eddies, which causes the water and gas to converge and tumble at the foaming chip, so that the gas and water can be better mixed to form more bubbles.

[0016] According to the above scheme, a flow-limiting hole is provided in the middle of the foam body. The upper end of the flow-limiting hole is connected to the lower end of the mixing chamber. A step is provided between the flow-limiting hole and the mixing chamber. The foam chip is fixed on the step. A baffle plate matching the foam chip is provided inside the flow-limiting hole. The lower end of the flow-limiting hole is connected to the water outlet. The diameter of the upper end of the flow-limiting hole is smaller than the diameter of the lower end of the mixing chamber to form the step, so that the foam chip can be placed on the step to form a limiting position. Furthermore, a snap-fit ​​structure, such as a rib or protrusion, can be provided on the inner wall of the mixing chamber above the step to match and clamp the foam chip for easy assembly.

[0017] According to the above scheme, the flow-limiting orifice includes a first buffer section and a second buffer section. A baffle plate is disposed between the first and second buffer sections, thereby forming a bent section within the flow-limiting orifice. The first buffer section is connected to the mixing chamber, and the second buffer section is connected to the outlet. The first buffer section, the bent section, and the second buffer section form a "Z"-shaped flow-limiting orifice, which causes the water flow passing through the foaming chip to turn to prevent water from splashing from the outlet. After the path changes after passing through the flow-limiting orifice, a stable water column with abundant and dense bubbles is formed.

[0018] According to the above scheme, the outlet is equipped with a guide nozzle, the guide nozzle has a guide hole, and the guide hole has a flow-turbating element. The upper end of the guide hole is connected to the second buffer section. The guide nozzle is used to control the shape of the water flow sprayed from the outlet. The aerated water from the mixing chamber is buffered by the flow-limiting hole and then shaped by the guide hole to form a stable water column.

[0019] Furthermore, the lower part of the foam body is provided with a water outlet, which facilitates the processing of the aforementioned flow-limiting holes, and a guide nozzle is provided inside the water outlet to better control the shape and stability of the water outlet.

[0020] Understandably, if the foam body is made of metal, a mixing chamber is first opened at the upper end of the foam body, and then an opening is made at the bottom of the mixing chamber to form the first buffer section. Next, an opening is made at the lower end of the foam body to form an outlet, and then a second buffer section and a bending section are opened in sequence. The diameter of the bending section is smaller than that of the second buffer section, and the bending section is eccentrically opened to form a flow-limiting hole with a "Z" shaped path.

[0021] If the foam is injection molded, the mold design is similar to the above-mentioned opening process, which should be well known to those skilled in the art, so it will not be described in detail here.

[0022] According to the above scheme, a limiting groove is provided on the inner wall of the outlet, and a convex ring is provided on the outer wall of the guide nozzle. The guide nozzle passes through the outlet, and the convex ring is snapped into the limiting groove, thereby fixing the guide nozzle to the foam body. The limiting groove and the convex ring are used to facilitate the assembly and fixing of the guide nozzle. Of course, the limiting groove and the convex ring can be replaced by conventional structures such as threads.

[0023] A beverage machine includes a main unit and an air-inlet foaming device. The main unit is equipped with an air supply component and a water supply component. The foaming body is fixedly connected to the main unit. The air supply component is connected to an air inlet pipe, and the water supply component is connected to a water inlet on the foaming body.

[0024] This utility model discloses an air-inlet foaming device in which the air inlet is tangent to the mixing chamber, causing the gas to drive the water to rotate along the inner wall of the mixing chamber. The liquid tumbles in the mixing chamber and mixes with the gas to generate bubbles. The foaming chip restricts the flow in the mixing chamber through the filter holes. The gas drives the water to rotate at high speed in the mixing chamber to form a vortex, which prolongs the flow path of the water in the mixing chamber and the gas-liquid mixing time, allowing the gas and water to mix again and the bubbles to be broken up, thereby forming a dense and rich bubble water column, which enhances the visual appeal and taste experience.

[0031] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0032] like Figure 1As shown, the present invention provides an air-intake foaming device, comprising a foaming body 1, wherein the foaming body 1 is provided with an inlet 11 and an outlet 12; a mixing chamber 13 is provided inside the foaming body 1, the mixing chamber 13 being connected to the inlet 11 and the outlet 12; an air inlet 14 is provided on the foaming body 1, the air intake direction of the air inlet 14 being tangential to the side wall of the mixing chamber 13; a foaming chip 2 is provided inside the mixing chamber 13, the foaming chip 2 being provided with a plurality of filter holes 21. Gas enters the mixing chamber 13 inside the foaming body 1 through the air inlet 14, and water enters the mixing chamber 13 inside the foaming body 1 through the inlet 11. The air intake direction of the air inlet 14 is tangential to the side wall of the mixing chamber 13, the gas drives the water to rotate at high speed in the mixing chamber 13 to form a vortex, prolonging the flow path of water in the mixing chamber 13 and the time of gas-liquid mixing, and the vortex causes the water and gas to tumble in the mixing chamber 13, which can generate more bubbles.

[0033] Furthermore, the foaming chip 2 restricts the flow of water in the mixing chamber 13 and disperses the bubbles in the water through several filter holes 21, turning large bubbles into small bubbles, thereby forming a rich and dense bubble water column at the outlet 12.

[0034] The mixing chamber 13 is vertically opened at the upper part of the foam body 1. The upper end of the mixing chamber 13 is connected to the water inlet 11, and the foaming chip 2 is disposed at the lower end of the mixing chamber 13. An air inlet pipe 15 is provided on the side wall of the foam body 1, and the air inlet pipe 15 is connected to the mixing chamber 13 through the air inlet hole 14.

[0035] The mixing chamber 13 is a circular hole. The water inlet 11, the mixing chamber 13 and the water outlet 12 are arranged in sequence from top to bottom. Water enters the mixing chamber 13 on the foam body 1 vertically.

[0036] The air intake pipe 15 is used to connect to the air source. The air intake pipe 15 is arranged in a horizontal direction and is connected to the mixing chamber 13 through the air intake hole 14.

[0037] The air intake direction of the air inlet 14 is tangent to the side wall of the mixing chamber 13. Specifically, in a horizontal cross-section, one of the contour edges of the air inlet 14 is tangent to the outer edge of the mixing chamber 13, so that the air inlet 14 and the mixing chamber 13 form a vortex structure. Gas enters the mixing chamber 13 horizontally from the air inlet 14, causing the gas to drive the water to rotate at high speed within the mixing chamber 13, forming a vortex.

[0038] Furthermore, as the water rotates in a vortex, the water at the edge of the mixing chamber 13 will roll towards the center, causing the water and gas to mix continuously to form more bubbles.

[0039] Furthermore, the foaming chip 2 is disposed at the lower end of the mixing chamber 13. The foaming chip 2 restricts the flow of water in the mixing chamber 13 and disperses the bubbles through several filter holes 21, turning large bubbles into small bubbles, thereby forming a rich and dense bubble water column at the water outlet 12.

[0040] The mixing chamber 13 is a conical hole that is larger at the top and smaller at the bottom. The angle between the side wall of the mixing chamber 13 and the horizontal plane is C, where 45°≤C≤89°. The mixing chamber 13 has a conical hole structure. The gas drives the water to rotate in the mixing chamber 13, generating a vortex. This causes the water and gas to converge and tumble at the foaming chip 2, allowing the gas and water to mix better and form more bubbles.

[0041] The foam body 1 has a flow-limiting hole 16 in its middle. The upper end of the flow-limiting hole 16 is connected to the lower end of the mixing chamber 13. A step 17 is provided between the flow-limiting hole 16 and the mixing chamber 13. The foam chip 2 is fixed on the step 17. A baffle plate 18 matching the foam chip 2 is provided inside the flow-limiting hole 16. The lower end of the flow-limiting hole 16 is connected to the water outlet 12. The diameter of the upper end of the flow-limiting hole 16 is smaller than the diameter of the lower end of the mixing chamber 13 to form the step 17, so that the foam chip 2 can be placed on the step 17 to form a limit. Furthermore, a snap-fit ​​structure, such as a rib or protrusion, can be provided on the inner wall of the mixing chamber 13 above the step 17 to match and clamp the foam chip 2 with the step 17 for easy assembly.

[0042] The flow-limiting orifice 16 includes a first buffer section 161 and a second buffer section 162. A baffle plate 18 is disposed between the first buffer section 161 and the second buffer section 162, thereby forming a bent section 163 within the flow-limiting orifice 16. The first buffer section 161 is connected to the mixing chamber 13, and the second buffer section 162 is connected to the outlet 12. The first buffer section 161, the bent section 163, and the second buffer section 162 form a "Z"-shaped flow-limiting orifice 16, which causes the water flow passing through the foaming chip 2 to turn to prevent water from splashing from the outlet 12. After the path changes after passing through the flow-limiting orifice 16, a stable water column with abundant and dense bubbles is formed.

[0043] The outlet 12 is equipped with a guide nozzle 3, which has a guide hole 31. The guide hole 31 has a flow-turbating element 32, and the upper end of the guide hole 31 is connected to the second buffer section 162. The guide nozzle 3 is used to control the shape of the water sprayed from the outlet 12. The aerated water from the mixing chamber 13 is buffered by the flow-limiting hole 16 and then shaped by the guide hole 31 to form a stable water column.

[0044] Furthermore, the lower part of the foam body 1 is provided with a water outlet 12, which facilitates the processing of the above-mentioned flow restriction hole 16, and a guide nozzle 3 is provided in the water outlet 12 to better control the shape and stability of the water outlet.

[0045] Understandably, if the foam body 1 is made of metal, a mixing chamber 13 is first opened at the upper end of the foam body 1, and then an opening is made at the bottom of the mixing chamber 13 to form the first buffer section 161. Next, an opening is made at the lower end of the foam body 1 to form an outlet 12, and then a second buffer section 162 and a bending section 163 are opened in sequence. The diameter of the bending section 163 is smaller than that of the second buffer section 162, and the bending section 163 is eccentrically opened to form a flow-limiting hole 16 with a "Z" shaped path.

[0046] If the foam 1 is injection molded, the mold design is similar to the above-mentioned opening process, which should be well known to those skilled in the art, so it will not be described in detail here.

[0047] The inner wall of the outlet 12 is provided with a limiting groove 120, and the outer wall of the guide nozzle 3 is provided with a protruding ring 33. The guide nozzle 3 passes through the outlet 12, so that the protruding ring 33 is snapped into the limiting groove 120, thereby fixing the guide nozzle 3 to the foam body 1. The limiting groove 120 and the protruding ring 33 are used to facilitate the assembly and fixing of the guide nozzle 3. Of course, the limiting groove 120 and the protruding ring 33 can be replaced by conventional structures such as threads.

[0048] A beverage machine includes a main unit 4 and an air-intake and foaming device. The main unit 4 is equipped with an air supply component 41 and a water supply component 42. A foaming body 1 is fixedly connected to the main unit 4. The air supply component 41 is connected to an air inlet pipe 15, and the water supply component 42 is connected to a water inlet 11 on the foaming body 1. The main unit 4 includes equipment for making beverages such as coffee machines, sparkling water machines, and juice machines, and can make beverages with rich bubbles, enhancing both visual appeal and taste experience.
