Description

Technical Field

[0001] The present application relates to the field of household appliances, and in particular to a milk frothing component and a coffee machine. Background Art

[0002] To meet diverse user needs and enhance the functionality of coffee machines, some commercially available machines are equipped with a milk frothing unit. This unit contains a mixing chamber that thoroughly mixes milk, air, and steam to form milk foam.

[0003] In the prior art, the mixing chamber is directly connected to the milk pipeline, and the milk enters the mixing chamber through the milk pipeline. That is, the milk frothing component does not have the function of adjusting the amount of milk, and can only produce milk froth with a single taste, which gives the user a poor experience. Utility Model Content

[0004] The present application provides a milk frothing component and a coffee machine, which can adjust the amount of milk entering the mixing chamber, thereby solving the problem that the milk frothing component can only produce milk froth with a single taste.

[0005] According to a first aspect of the present application, a milk frothing assembly is provided, comprising: a milk frothing device having a mixing chamber, a steam inlet, an air inlet, and a milk frothing outlet, wherein the steam inlet, the air inlet, and the milk frothing outlet are respectively connected to the mixing chamber; the milk frothing device further having a milk suction channel, wherein the milk suction channel is provided with a milk suction hole, and the milk suction channel is connected to the mixing chamber through the milk suction hole; and a regulating valve comprising a valve core, wherein the valve core is rotatably installed in the milk suction channel, and the valve core is provided with a milk volume regulating hole, wherein the milk volume regulating hole is used to change the effective communication area of ​​the milk suction hole during the rotation of the valve core relative to the milk suction channel, so as to regulate the amount of milk entering the mixing chamber.

[0006] In the above embodiment, when the user controls the valve core to rotate in the milk suction channel, the relative position of the milk volume adjustment hole and the milk suction hole changes, thereby changing the overlapping area of ​​the milk volume adjustment hole and the milk suction hole, thereby changing the effective communication area of ​​the milk suction hole for milk to be introduced, thereby adjusting the amount of milk entering the mixing chamber. If the overlapping area of ​​the milk volume adjustment hole and the milk suction hole increases, the effective communication area of ​​the milk suction hole increases, and the amount of milk entering the mixing chamber increases. Under the condition that the amount of air introduced remains unchanged, the milk foam produced by the milk frothing device decreases, the milk foam tastes more dense, and the milk foam temperature decreases. If the overlapping area of ​​the milk volume adjustment hole and the milk suction hole decreases, the effective communication area of ​​the milk suction hole decreases, and the amount of milk entering the mixing chamber decreases. Under the condition that the amount of air introduced remains unchanged, the milk foam produced by the milk frothing device increases, and the milk foam temperature increases. Therefore, by providing a regulating valve with a milk amount regulating hole, the amount of milk introduced into the mixing chamber can be controlled, and the ratio of milk to air can be changed, so that the milk frothing device can prepare milk froth with different tastes and temperatures, achieving a milk frothing effect with diversified flavors, which is beneficial to improving the user experience.

[0007] In a possible design, the milking hole includes a plurality of sub-milking holes distributed in an array.

[0008] In the above solution, the aperture of the sub-milk suction hole is relatively small, which has the effect of filtering and diffusing the milk entering the mixing chamber, and is beneficial to improving the mixing effect of the milk foam in the mixing chamber.

[0009] In a possible design, the air inlet is provided on a side wall of the milk suction channel; the milk suction channel is further provided with an air suction hole, and the air inlet is connected to the mixing chamber via the air suction hole.

[0010] In the above solution, external air can enter the mixing chamber through the air inlet, the milk suction channel and the air suction hole, that is, one milk suction channel is used to achieve both air intake and milk intake, which is beneficial to simplify the structure of the milk frothing device and reduce the volume of the milk frothing device.

[0011] In a possible design, the valve core is further provided with a ventilation groove; the ventilation groove is used to connect the air inlet and the suction hole during the rotation of the valve core relative to the milk suction channel, so that the air in the air inlet can enter the mixing chamber through the suction hole; the ventilation groove is also used to be misaligned with the suction hole and / or the air inlet during the rotation of the valve core relative to the milk suction channel, so as to block the air in the air inlet from entering the mixing chamber through the suction hole.

[0012] In the above scheme, if the ventilation groove is connected to the air inlet and the air intake hole at the same time, the air in the air inlet can enter the mixing chamber through the air intake hole; if the ventilation groove is misaligned with at least one of the air inlet and the air intake hole, that is, the side wall of the valve core blocks the air inlet and / or the bottom wall of the valve core blocks the air intake hole, the air inlet and the air intake hole cannot be connected, thereby blocking the air in the air inlet from entering the mixing chamber through the air intake hole. At this time, only milk and steam are introduced into the mixing chamber, which can maximize the milk ratio. That is, by providing the ventilation groove, the amount of air introduced into the mixing chamber can be controlled.

[0013] In a possible design, the regulating valve further includes a valve body fixedly connected to the valve core; the valve body is provided with an abutment platform, and the abutment platform abuts and cooperates with the inlet of the milk suction channel.

[0014] In the above solution, the abutment platform abuts against the inlet of the milk suction channel, which is conducive to the valve body and the milk suction channel to form a sealed fit. Since the valve body is exposed, the user can control the valve core to rotate in the milk suction channel by rotating the valve body.

[0015] In a possible design, the valve body is provided with a handle, and the handle protrudes outward in a radial direction of the valve body.

[0016] In the above solution, the user can rotate the valve body by turning the handle, which is more labor-saving and can be operated with a single finger, making it more convenient for users to use.

[0017] In a possible design, the side wall of the valve body is further provided with an anti-slip groove, and a plurality of the anti-slip grooves are distributed at intervals along the circumference of the valve body.

[0018] In the above solution, the anti-skid groove can increase the friction on the side wall of the valve body, and play an anti-skid role when the user rotates the valve body.

[0019] In a possible design, the milk frothing assembly further includes a milk pipeline, and the valve body is respectively connected to the milk pipeline and the milk quantity adjustment hole; one end of the milk pipeline is sealed with the valve body, and the other end is used to be placed in a container containing milk.

[0020] In the above solution, the milk pipeline is used to introduce milk into the milk frothing device, and the sealing connector is used to improve the sealing between the valve body and the milk pipeline.

[0021] In a possible design, the milk frothing component further includes a milk frothing nozzle, which is mounted on the milk frothing outlet, and the milk frothing nozzle and / or the milk frothing outlet are provided with milk frothing sieve holes.

[0022] In the above solution, the milk foam nozzle can guide the milk foam at the milk foam outlet to ensure that the milk foam flows directly into the container for receiving the milk foam. By setting the milk foam sieve hole, the milk foam formed in the mixing chamber can be filtered to improve the taste of the milk foam.

[0023] A second aspect of the present application provides a coffee machine, comprising: a main body; and a milk frothing component, wherein the milk frothing component is the milk frothing component described above, and the milk frothing component is detachably connected to the main body.

[0024] In the above solution, the milk frothing component can prepare milk froth with different tastes, which can improve the experience of using the coffee machine. Moreover, the milk frothing component is detachably connected to the main body, which makes it convenient for users to clean the interior of the milk frothing device and reduce bacterial growth.

[0062] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0063] It should be clear that the embodiments described are only part of the embodiments of this application, not all of the embodiments.

The singular forms "a", "an", "the" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0065] It should be understood that the term "and / or" as used herein is merely a description of the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0066] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described based on the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should be understood that when it is mentioned that an element is connected to another element "on" or "under", it can not only be directly connected to the other element "on" or "under", but also be indirectly connected to the other element "on" or "under" through an intermediate element.

[0067] The embodiment of the present application provides a coffee machine, such as Figure 1 As shown, the coffee machine includes a main body 100 and a milk frothing component 200. The milk frothing component 200 can realize the milk frothing function of the coffee machine and improve the practicality of the coffee machine. Figure 2 As shown, the milk frothing assembly 200 includes a milk frothing device 1, a regulating valve 2 installed on the milk frothing device 1, and a milk pipeline 3 connected to the milk frothing device 1 through the regulating valve 2. Figure 3 and Figure 4As shown, the milk frothing device 1 includes a mixing chamber 11, a steam inlet 12, an air inlet 13, a milk frothing outlet 14, and a milk suction channel 15. The steam inlet 12, the air inlet 13, and the milk frothing outlet 14 are respectively connected to the mixing chamber 11. The steam inlet 12 is connected to the steam outlet on the main body 100 to allow steam to enter the mixing chamber 11. The air inlet 13 is directly connected to the outside world to allow air to enter the mixing chamber 11. The milk suction channel 15 is provided with a milk suction hole. One end of the milk suction channel 15 is connected to the milk pipeline 3 through the regulating valve 2, and the other end is connected to the mixing chamber 11 through the milk suction hole 151. The end of the milk pipeline 3 away from the regulating valve 2 is used to extend into the milk container 400 to allow milk to enter the mixing chamber 11. According to Bernoulli's principle, when the steam inlet 12 introduces steam with a relatively high flow rate into the mixing chamber 11, the pressure in the mixing chamber 11 decreases, thereby sucking milk and air into the mixing chamber 11, so that the steam, milk and air are fully mixed in the mixing chamber to form milk foam, which then flows out to the outside through the milk foam outlet 14. Figure 1 As shown, the milk foam outlet 14 can be aligned with the cup 300, allowing the prepared milk foam to flow directly into the cup 300, which is convenient for users to use.

[0068] like Figure 5 As shown, the regulating valve 2 specifically includes a valve core 21 and a valve body 22 connected to each other. The valve core 21 is rotatably installed in the milk suction channel 15. The valve core 21 is provided with a milk volume adjustment hole 211. The milk volume adjustment hole 211 is a through-hole structure, which is used to connect the milk pipeline 3 and the milk suction hole 151. When the user controls the valve core 21 to rotate in the milk suction channel 15, the relative position of the milk volume adjustment hole 211 and the milk suction hole 151 changes, which can change the overlapping area of ​​the milk volume adjustment hole 211 and the milk suction hole 151. In other words, it changes the communication area between the milk suction hole 151 and the milk pipeline 3, thereby changing the effective communication area of ​​the milk suction hole 151 for milk to enter, thereby adjusting the amount of milk entering the mixing chamber 11. If the overlapping area between the milk volume adjustment hole 211 and the milk suction hole 151 increases, the effective communication area of ​​the milk suction hole 151 increases, and the amount of milk entering the mixing chamber 11 increases. Under the condition that the amount of air introduced remains unchanged, the milk foam in the milk froth produced by the milk frothing device 1 becomes less, the milk foam tastes smoother, and the milk foam temperature becomes lower. If the overlapping area between the milk volume adjustment hole 211 and the milk suction hole 151 decreases, the effective communication area of ​​the milk suction hole 151 decreases, and the amount of milk entering the mixing chamber 11 becomes less. Under the condition that the amount of air introduced remains unchanged, the milk foam in the milk froth produced by the milk frothing device 1 becomes more, and the milk foam temperature becomes higher. Therefore, by providing the regulating valve 2 with the milk volume adjustment hole 211, the amount of milk introduced into the mixing chamber 11 can be controlled, the ratio of milk to air can be changed, and the milk froth device 1 can prepare milk foam with different tastes and temperatures, achieving a milk froth with diverse flavors, and thus improving the user experience.

[0069] like Figure 2 As shown, an indicator mark 18 can be provided on the outside of the milk frothing device 1 to remind the user in which direction the valve core 21 is rotated to increase the amount of milk introduced. The indicator mark 18 can be Figure 2 The multiple circular marks of different sizes shown in the figure may also be arrows or marks of other shapes, which is not limited in this embodiment.

[0070] like Figure 5 and Figure 6 As shown, the shape and size of the milk volume adjustment hole 211 should match the milk suction hole 151, and the cross-sectional area of ​​the milk volume adjustment hole 211 should be greater than or equal to the cross-sectional area of ​​the milk suction hole 151, so as to ensure that when the overlapping area of ​​the milk volume adjustment hole 211 and the milk suction hole 151 is maximized, the milk suction hole 151 is fully open and can be fully connected with the milk pipe 3, and the milk suction hole 151 will not be partially blocked.

[0071] In a specific embodiment, the milk suction hole 151 can be an independent through-hole structure, and the specific shapes of the milk suction hole 151 and the milk volume adjustment hole 211 can be circular, rectangular, trapezoidal or fan-shaped, etc., which is not limited in this embodiment.

[0072] Or, in another specific embodiment, Figure 6 As shown, the milking hole 151 may also be composed of a plurality of sub-milk-sucking holes 151a distributed in an array. The sub-milk-sucking holes 151a have a smaller aperture and filter and diffuse the milk entering the mixing chamber 11, thereby improving the mixing effect of the milk foam in the mixing chamber 11. The specific shape of the sub-milk-sucking holes 151a can be square, rectangular, circular, or diamond-shaped, etc., which is not limited in this embodiment. The specific shape of the milking hole 151 formed by the multiple sub-milk-sucking holes 151a can be circular, rectangular, trapezoidal, or fan-shaped, etc., which is not limited in this embodiment. It is only necessary to ensure that the shape of the milking hole 151 matches that of the milk volume adjustment hole 211.

[0073] In a specific embodiment, the air inlet 13 can be connected to the mixing chamber 11 through a channel, that is, the milk frothing device 1 can be a four-way structure, and the mixing chamber 11 is connected to the steam inlet 12, the air inlet 13, the milk froth outlet, and the milk suction channel 15 through four channels respectively.

[0074] Or, in another specific embodiment, Figure 4As shown, the air inlet 13 can be provided on the side wall of the milk suction channel 15, so that the outside air 13 flows directly into the milk suction channel 15. At the same time, the milk suction channel 15 is also provided with an air suction hole 152. The air inlet 13 is connected to the mixing chamber 11 through the air suction hole 152, so that the outside air can enter the mixing chamber 11. This embodiment uses a single milk suction channel 15 to achieve both air intake and milk intake, which helps to simplify the structure of the milk frothing device 1 and reduce the volume of the milk frothing device 1.

[0075] Furthermore, if Figure 5 and Figure 6 As shown, a vent groove 212 can be provided on the valve core 21. During the rotation of the valve core 21 relative to the milk suction channel 15, if the vent groove 212 is connected to the air inlet 13 and the suction hole 152 at the same time, the air in the air inlet 13 can enter the mixing chamber 11 through the suction hole 152. If the vent groove 212 is misaligned with at least one of the air inlet 13 and the suction hole 152, that is, the side wall of the valve core 21 blocks the air inlet 13 and / or the bottom wall of the valve core 21 blocks the suction hole 152, the air inlet 13 and the suction hole 152 cannot be connected, thereby preventing the air in the air inlet 13 from entering the mixing chamber 11 through the suction hole 152. At this time, only milk and steam are introduced into the mixing chamber 11, which can maximize the milk ratio. That is, by providing the vent groove 212, the amount of air introduced into the mixing chamber 11 can be controlled.

[0076] Preferably, the vent groove 212 can be set to the same shape as the milk amount adjustment hole 211. During the process of adjusting the overlapping area of ​​the milk amount adjustment hole 211 and the milk suction hole 151, the vent groove 212 can always remain connected to the air inlet 13 and the air suction hole 152, that is, the amount of air introduced into the mixing chamber 11 remains unchanged; only when the overlapping area of ​​the milk amount adjustment hole 211 and the milk suction hole 151 is the largest, that is, the amount of milk introduced into the mixing chamber 11 is the largest, will the vent groove 212 be misaligned with at least one of the air inlet 13 and the air suction hole 152, thereby blocking air from entering the mixing chamber 11.

[0077] In a specific embodiment, Figure 3 As shown, the valve body 22 is located outside the milk suction channel 15 and is provided with an abutment platform 223. The abutment platform 223 abuts against the entrance of the milk suction channel 15, facilitating a sealed fit between the valve body 22 and the milk suction channel 15. Since the valve body 22 is exposed to the outside, the user can control the rotation of the valve core 21 within the milk suction channel 15 by rotating the valve body 22.

[0078] Furthermore, anti-slip grooves 222 may be provided on the sidewalls of the valve body 22. Multiple anti-slip grooves 222 are spaced apart along the circumference of the valve body 22 to increase friction on the sidewalls of the valve body 22, thereby preventing the user from slipping when rotating the valve body 22. Furthermore, the valve body 22 may be provided with a handle 221 that protrudes radially outward from the valve body 22. The user can rotate the valve body 22 by turning the handle 221, which saves effort and can be operated with a single finger, making it more convenient for the user.

[0079] The valve body 22 is provided with a through groove 224, which is used to connect the milk pipeline 3 with the milk amount adjustment hole 211. Specifically, a sealing connector 4 is also provided in the valve body 22. The milk pipeline 3 is installed on the valve body 22 through the sealing connector 4 and is connected with the through groove 224 through the sealing connector 4. The sealing connector 4 is used to improve the sealing between the valve body 22 and the milk pipeline 3.

[0080] In one specific embodiment, the milk frothing assembly 200 further includes a milk frothing nozzle 5, which is mounted on the milk frothing outlet 14 and can guide the milk froth at the milk frothing outlet 14, ensuring that the milk froth flows directly into the cup 300. Furthermore, the milk frothing nozzle 5 and / or the milk frothing outlet 14 are provided with a milk frothing sieve, which can filter the milk froth formed in the mixing chamber 11 to enhance the taste of the milk froth. Specifically, the milk frothing nozzle 5 can be fixedly connected to the milk frothing outlet 14 or detachably connected thereto, which is not a limitation in this embodiment.

[0081] In a specific embodiment, Figure 2 As shown, the milk frothing device 1 is provided with a mounting portion 16, which can be detachably connected to the main body 100, so as to facilitate the user to clean the interior of the milk frothing device 1 and reduce the growth of bacteria. The mounting portion 16 can be specifically provided at a position close to the steam inlet 12, and correspondingly, a mounting matching portion corresponding to the mounting portion 16 can be provided at a position close to the steam outlet of the main body 100. The mounting portion 16 can be specifically provided at a position close to the steam outlet of the main body 100. Figure 2 In the mounting post structure shown in FIG, the mounting mating portion can be specifically a snap-fit ​​groove, and the mounting portion 16 can be connected to the mounting mating portion by rotating the milk frothing device 1. Alternatively, the mounting portion 16 and the mounting mating portion can be mated using a threaded connection or a lock connection. This embodiment does not limit the specific structures of the mounting portion 16 and the mounting mating portion.

[0082] In addition, if Figure 2 As shown, a sealing ring 17 is further provided at the steam inlet 12 for forming a sealed fit between the steam inlet 12 and the steam outlet on the main body 100 to avoid steam leakage and ensure the air and milk suction effect of the milk frothing device 1.

[0083] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
