Description
Technical Field
[0001] The utility model belongs to the field of liquid foaming, and in particular relates to a coffee machine foamer. Background Art
[0002] With the improvement of living standards, coffee has gradually become an integral part of people's lives, and the requirements for coffee drinking are getting higher and higher. The coffee foam oil esters are not delicate, and the oil ester layer is not thick enough, and there are more coarse foams, resulting in a poor taste of coffee. In addition, problems such as insufficient coffee oil and insufficient oil extraction often occur, which poses a great challenge to the production and debugging of espresso machines.
[0003] In view of the above situation, the existing coffee machine foamer sprays the coffee liquid at high pressure, so that the coffee liquid undergoes a foaming process in the foamer, thereby improving the oil fineness and thickness of the oil layer of the coffee foam. However, the coffee oil foamed once is still relatively small, and the effect of the coffee oil is still not delicate and mellow enough. Summary of the invention
[0004] The utility model aims to provide a coffee machine foamer, in which coffee liquid can be mixed and foamed for multiple times in a foaming chamber, so that the foam oil ester layer of the coffee liquid is thicker and more delicate.
[0005] The technical solution is as follows:
[0006] A coffee machine foamer comprises a main shell, one end of which is provided with a liquid inlet chamber, and the other end of which is provided with a foaming chamber, a liquid inlet is arranged in the main shell, and the liquid inlet chamber is connected to the foaming chamber through the liquid inlet, a liquid outlet is also arranged at the bottom of the main shell, and the liquid outlet is connected to the foaming chamber, an air inlet is arranged on one side of the main shell, and the air inlet is connected to the foaming chamber; a first blocking member and a second blocking member are also arranged in the foaming chamber, the second blocking member is fixedly connected to the bottom of the main shell, and the second blocking member has a first blocking surface at one end close to the liquid inlet, the first blocking member is arranged on the second blocking member, the first blocking member is coaxially arranged with the liquid inlet, the first blocking member is close to the liquid inlet and forms a jet, and the first blocking surface is used to receive the liquid jetted from the jet.
[0007] By adopting the above technical scheme, the coffee liquid flows into the foaming chamber from the liquid inlet through the liquid inlet. Since the first blocking member is close to the liquid inlet, the coffee liquid impacts the first blocking member from the liquid inlet. There is a gap between the first blocking member and the liquid inlet, thereby forming the injection port. The coffee liquid is then sprayed from the injection port toward the first blocking surface, thereby causing the high-speed sprayed coffee liquid to sputter. During high-speed spraying, a negative pressure siphon effect is generated in the foaming chamber, and external air flows into the foaming chamber through the air inlet. The sprayed coffee liquid mixes with the air to form the first foaming liquid. Under the action of the siphon, the splashed part of the first coffee foaming liquid approaches the injection port and mixes with the sprayed coffee liquid. The foaming process is continuously circulated to form a mixed foaming liquid. Another splashed part of the first foaming liquid and the multiple mixed foaming liquids flow out from the liquid outlet at the bottom of the foaming chamber, thereby making the foam oil ester layer of the coffee liquid thicker and finer.
[0008] In one of the embodiments, a first protrusion is further provided in the main shell, and the first protrusion is located in the foaming cavity; the first protrusion surrounds the liquid inlet, and a second blocking surface is provided at one end of the first protrusion, and the second blocking surface corresponds to the first blocking surface.
[0009] By adopting the above technical solution, under the siphon effect of the air in the foaming chamber, the first protrusion shortens the distance between the first blocking surface and the liquid outlet, so that more first foaming liquid will rebound to the second blocking surface after splashing from the first blocking surface, and the first foaming liquid will splash again after passing through the second blocking surface, so that the foaming liquid foam is smaller, and then mixed with the high-speed liquid sprayed from the injection port, and the foaming process is repeated multiple times, so that the oil ester layer of the coffee liquid foam is further made thicker and finer.
[0010] In one embodiment, along the radial direction of the main shell, the radial dimension of the second blocking surface is greater than the radial dimension of the first blocking surface.
[0011] By adopting the above technical solution, the foaming liquid sprayed at high speed moves away from the injection port after being splashed by the first blocking surface. The radial dimension of the second blocking surface is larger than the radial dimension of the first blocking surface, so that more foaming liquid splashed outward can rebound to the second blocking surface, thereby making more foaming liquid particles smaller and forming finer liquid foam after mixing with air.
[0012] In one of the embodiments, along the axial direction of the main shell, the air inlet hole is located obliquely above the second blocking surface.
[0013] By adopting the above technical solution, the air inlet is close to the second blocking surface. Due to the siphon effect, the inflowing air will flow to the vicinity of the injection port more quickly, and the air will first flow from above the second blocking surface to the injection port, so that the liquid splashed by the first blocking surface moves more toward the second blocking surface, and moves back toward the injection port after splashing by the second blocking surface, thereby ensuring that more splashed liquid is mixed and foamed.
[0014] In one embodiment, the second blocking member is hollow, and a first column is also provided in the foaming cavity, and the second blocking member is sleeved on the first column; a first elastic member is also provided between the second blocking member and the first column, and the first elastic member is sleeved on the first column, the first blocking member is installed on the first elastic member, and the first blocking member abuts against the liquid inlet.
[0015] By adopting the above technical solution, the second blocking member and the first elastic member are installed through the first column. The first elastic member enables the first blocking member to abut against the liquid inlet, thereby increasing the force of the liquid impacting the first blocking member so that a jet port can be formed between the first blocking member and the liquid inlet, thereby increasing the pressure and speed of the liquid injection, thereby making the particle size of the injected liquid smaller. After multiple cycles of foaming, the foam formed by a unit volume of liquid is more delicate and mellow.
[0016] In one embodiment, the liquid inlet is a circular hole, the first blocking member is a sphere, the diameter of the first blocking member is larger than the aperture of the liquid inlet, and the first blocking surface is annular.
[0017] By adopting the above technical solution, the first blocking member is a sphere, which can reduce the friction loss of the liquid impacting the first blocking member when it is ejected from the injection port, so that the injected liquid can be more smoothly ejected from the injection port to the first blocking surface, and the spherical first blocking member cooperates with the circular liquid inlet, so that the liquid particles sprayed from the injection port to the surrounding areas are more evenly distributed. The annular first blocking surface also makes the liquid particles after sputtering more evenly distributed, improves the uniformity of the foaming of the liquid particles, and thus ensures the fineness of the liquid foam.
[0018] In one of the embodiments, along the axial direction of the main shell, the distance between the first blocking surface and the main shell located at the upper end of the foaming cavity is smaller than the diameter of the first blocking member.
[0019] By adopting the above technical solution, the spherical first blocking member is stably installed between the second blocking member and the liquid inlet, so that the sprayed liquid is always sprayed from the spray port to the first blocking surface and then splashed, thereby ensuring the stability of the liquid circulation foaming process.
[0020] In one embodiment, a through hole is provided in the middle of the second blocking member, and along the axial direction of the second blocking member, the second blocking member located at the lower end of the through hole matches the first column, the inner diameter of the second blocking member upward along the through hole is larger than the diameter of the first column, and one end of the first elastic member is close to the lower end of the through hole.
[0021] By adopting the above technical solution, when the liquid impacts the second blocking member, part of the liquid flows along the second blocking member to the hollow interior of the first blocking member. Since the first elastic member is located between the first column and the second blocking member, the long-term residual liquid will corrode the first elastic member. The through hole can discharge the residual liquid into the foaming cavity and discharge it from the liquid outlet, thereby ensuring the service life of the first elastic member and the pressure on the first blocking member.
[0022] In one embodiment, the main shell includes a first shell and a second shell, the liquid inlet cavity is located at one end of the first shell, and the liquid inlet is provided in the middle of the first shell; the second shell is fixedly connected to the other end of the first shell, and the foaming cavity is formed between the second shell and the first shell.
[0023] By adopting the above technical solution, the separate structure of the first shell and the second shell facilitates the installation and disassembly of the main shell and various components, and when one of the components is damaged, it is easy to replace and repair it.
[0024] In one embodiment, a rib is provided at the other end of the first shell, the rib is located outside the liquid inlet, and the rib also extends to one side of the second blocking member; the foaming cavity includes a first foaming area and a second foaming area, the first foaming area is formed between the first blocking surface and the first shell, and the second foaming area is formed between the second blocking member and the rib.
[0025] By adopting the above technical scheme, after the sprayed liquid is mixed and foamed in the first foaming zone, it gradually flows to the second foaming zone. Since the liquid particles splashed to the second foaming zone still have a relatively high speed, the mixed foaming liquid will collide with the ribs and splash and rebound to the side wall of the second blocking member, and part of the liquid will splash and rebound multiple times between the ribs and the side wall of the second blocking member. Multiple splashing further makes the particle size of the foaming liquid in the second foaming zone smaller, and is further mixed and foamed with the air under the siphon effect, thereby improving the fineness and mellowness of the foaming liquid per unit volume.

[0038] like Figures 1 to 6The coffee machine foamer shown in the figure comprises a main shell 10, wherein the main shell 10 comprises a first shell 20 and a second shell 30. The separate structure of the first shell 20 and the second shell 30 facilitates the installation and disassembly of the main shell 10 and various components, and facilitates replacement and repair when one of the components is damaged; a liquid inlet cavity 21 is provided at one end of the first shell 20, and the second shell 30 is fixedly connected to the other end of the first shell 20, and a foaming cavity 31 is formed between the second shell 30 and the first shell 20; a liquid inlet port 22 is provided in the middle of the first shell 20, and the liquid inlet port 22 is provided in the middle of the first shell 20. The cavity 21 is connected to the foaming cavity 31 through the liquid inlet 22. The bottom of the second shell 30 is also provided with a liquid outlet 32, and the liquid outlet 32 is connected to the foaming cavity 31. One side of the main shell 10 is provided with an air inlet 11, and the air inlet 11 is connected to the foaming cavity 31. The foaming cavity 31 is also provided with a first blocking member 33 and a second blocking member 34. The second blocking member 34 is fixedly connected to the bottom of the second shell 30. The end of the second blocking member 34 close to the liquid inlet 22 also has a first blocking surface 341. The first blocking member 33 is arranged on the second On the blocking member 34, the first blocking member 33 is coaxially arranged with the liquid inlet 22; the coffee liquid flows from the liquid inlet cavity 21 into the foaming cavity 31 through the liquid inlet 22, the first blocking member 33 is close to the liquid inlet 22, and the coffee liquid impacts the first blocking member 33 from the liquid inlet 22, and there is a gap between the first blocking member 33 and the liquid inlet 22, thereby forming the injection port 12, and the injection port 12 corresponds to the first blocking surface 341, and the coffee liquid is then sprayed from the injection port 12 to the first blocking surface 341, so that the high-speed injection The coffee liquid is sputtered. When it is sprayed at a high speed, a negative pressure siphon effect is generated in the foaming chamber 31. External air flows into the foaming chamber 31 through the air inlet 11, and the sprayed coffee liquid is mixed with the air to form a first foaming liquid. Under the action of the siphon, part of the first foaming coffee liquid is sputtered and moves toward the spray port 12 to mix with the sprayed coffee liquid. The foaming process is continuously circulated to form a mixed foaming liquid. Another part of the first foaming liquid and the multiple mixed foaming liquids are sputtered and flow out from the liquid outlet 32 at the bottom of the foaming chamber 31, thereby making the foam oil ester layer of the coffee liquid thicker and finer.
[0039] like Figures 2 to 5 As shown, further description of the first housing 20 is as follows:
[0040] A first protrusion 24 is further provided at the other end of the first shell 20, and the first protrusion 24 is located in the foaming cavity 31; the first protrusion 24 surrounds the liquid inlet 22, and a second blocking surface 241 is provided at one end of the first protrusion 24, and the second blocking surface 241 corresponds to the first blocking surface 341; under the siphon effect of the air in the foaming cavity 31, the first protrusion 24 shortens the distance between the first blocking surface 341 and the liquid outlet 32, so that more first foaming liquid will rebound to the second blocking surface 241 after splashing from the first blocking surface 341, and along the radial direction of the main shell 10, the radial dimension of the second blocking surface 241 is greater than the radial dimension of the first blocking surface 341, so that more foaming liquid splashing outward can rebound to the second blocking surface 241, passing through the second blocking surface 241, the first foaming liquid after sputtering is sputtered again, so that the foaming liquid foam is smaller, and then mixed with the high-speed liquid sprayed from the injection port 12, and the foaming process is repeated for multiple times, so that the oil layer of the coffee liquid foam is further thicker and finer; along the axial direction of the main shell 10, the air inlet 11 is located obliquely above the second blocking surface 241, and the air inlet 11 is close to the second blocking surface 241. Due to the siphon effect, the inflowing air will flow faster to the vicinity of the injection port 12, and the air first flows from above the second blocking surface 241 to the injection port 12, so that the liquid sputtered through the first blocking surface 341 moves more toward the second blocking surface 241, and moves back and forth toward the injection port 12 after sputtering through the second blocking surface 241, so as to ensure that more sputtered liquid is mixed and foamed.
[0041] The other end of the first shell 20 is further provided with a rib 23, the rib 23 is located outside the liquid inlet 22, and the rib 23 also extends to one side of the second blocking member 34, and the rib 23 is close to the second blocking member 34 relative to the side wall of the second shell 30; the foaming cavity 31 includes a first foaming area 311 and a second foaming area 312, the first foaming area 311 is formed between the first blocking surface 341 and the first shell 20, and the second foaming area 312 is formed between the second blocking member 34 and the rib 23; the sprayed liquid is sprayed in the first foaming area 31 After being mixed and foamed, the liquid gradually flows to the second foaming area 312. Since the liquid particles splashed to the second foaming area 312 still have a relatively high speed, the mixed foaming liquid will collide with the ribs 23 and splash and rebound to the side wall of the second blocking member 34, and part of the liquid will splash and rebound multiple times between the ribs 23 and the side wall of the second blocking member 34. Multiple splashing further makes the particle size of the foaming liquid in the second foaming area 312 smaller, and further mixes and foams with the air under the siphon effect, thereby improving the fineness and mellowness of the foaming liquid per unit volume.
[0042] like Figures 2 to 6 As shown, the liquid inlet 22, the first blocking member 33, and the second blocking member 34 are further described:
[0043] The second blocking member 34 is hollow, and a first column 35 is further provided in the foaming chamber 31, and the second blocking member 34 is sleeved on the first column 35; a first elastic member 36 is further provided between the second blocking member 34 and the first column 35, and the first elastic member 36 is sleeved on the first column 35, and the first blocking member 33 is installed on the first elastic member 36, and the first elastic member 36 enables the first blocking member 33 to abut against the liquid inlet 22, so that the force of the liquid impacting the first blocking member 33 is increased, and the injection port 12 can be formed between the first blocking member 33 and the liquid inlet 22, thereby increasing the pressure and speed of the liquid injection, thereby making the injected liquid particle size smaller, and after multiple cycles of foaming, the foam formed by the unit volume of liquid is more delicate and mellow; the liquid inlet 22 is a round hole, the first blocking member 33 is a sphere, the diameter of the first blocking member 33 is larger than the aperture of the liquid inlet 22, and the first blocking surface 341 is annular; The first blocking member 33 is a sphere, which can reduce the friction loss of the liquid impacting the first blocking member 33 when it is ejected from the injection port 12, so that the injected liquid can be more smoothly ejected from the injection port 12 to the first blocking surface 341, and the spherical first blocking member 33 cooperates with the circular liquid inlet 22, so that the liquid particles ejected from the injection port 12 to the surroundings are more evenly distributed, and the annular first blocking surface 341 also makes the liquid particles after sputtering more evenly distributed, improves the uniformity of the foaming of the liquid particles, and thus ensures the fineness of the liquid foam; along the axial direction of the main shell 10, the distance between the first blocking surface 341 and the main shell 10 located at the upper end of the foaming chamber 31 is smaller than the diameter of the first blocking member 33, so that the spherical first blocking member 33 is stably installed between the second blocking member 34 and the liquid inlet 22, so that the injected liquid is always sputtered after being ejected from the injection port 12 to the first blocking surface 341, thereby ensuring the stability of the liquid circulation foaming process.
[0044] When the liquid impacts the second blocking member 34, part of the liquid flows along the second blocking member 34 to the hollow interior of the first blocking member 33. Since the first elastic member 36 is located between the first column 35 and the second blocking member 34, the long-term residual liquid will corrode the first elastic member 36. A through hole 342 is also provided in the middle of the second blocking member 34. Along the axial direction of the second blocking member 34, the second blocking member 34 located at the lower end of the through hole 342 matches the first column 35 to prevent the residual liquid from continuing to flow below the through hole 342. The inner diameter of the second blocking member 34 upward along the through hole 342 is greater than the diameter of the first column 35. One end of the first elastic member 36 is close to the lower end of the through hole 342, so that the through hole 342 can discharge all the residual liquid into the foaming cavity 31 and discharge it from the liquid outlet 32, thereby ensuring the service life of the first elastic member 36 and the pressure on the first blocking member 33.
[0045] The above embodiments are not exhaustive enumerations based on the present invention, and there may be multiple other implementations not listed. Any replacement and improvement made without violating the concept of the present invention shall fall within the protection scope of the present invention.
