Description

Technical Field

[0001] The present invention relates to the field of coffee machines, and in particular, to a portable coffee machine that is easy to clean. Background Art

[0002] When using coffee powder to make coffee with a portable coffee machine, it is necessary to first add the coffee powder to the corresponding container, install the corresponding container on the portable coffee machine, then add the corresponding amount of water to the portable coffee machine, heat the water through the heater in the portable coffee machine, and then use the pump in the portable coffee machine to transport the heated water into the container filled with coffee powder. When the heated water passes through the coffee powder in the corresponding container, the water and coffee powder are mixed and transferred out to form coffee. However, due to the limited capacity of the portable coffee machine, it is necessary to add water to the portable coffee machine multiple times to obtain a full cup of coffee.

[0003] During the use of the portable coffee machine, the following problems exist:

[0004] 1. Due to the limited internal space of the portable coffee machine, the pump in the portable coffee machine cannot provide a high pressure for the water. When the water is mixed with the coffee powder, the impact force of the water is insufficient, so that the coffee powder on the upper layer of the corresponding container is fully mixed and better extracted, while the coffee powder on the lower layer of the corresponding container is mixed with the water after being weakened by the upper layer of coffee powder, so that the coffee powder on the lower layer of the corresponding container cannot be well extracted, resulting in waste of the coffee powder on the lower layer of the corresponding container due to insufficient use.

[0005] 2. The existing portable coffee machines can only use either coffee powder or coffee capsules. When the existing portable coffee machines use coffee capsules to make coffee, they cannot completely break open the aluminum foil of the coffee capsules, reducing the flow area of the heated water and preventing it from being fully mixed with the coffee powder. Since the ratio of coffee powder to water in the coffee capsule is set, the coffee powder in the coffee capsule cannot be effectively used, resulting in waste of the coffee powder. At the same time, the ratio of coffee powder to water is affected, leading to problems with the taste of the coffee. Summary of the Invention

[0006] In order to overcome the drawbacks that the coffee powder cannot be well extracted and the coffee powder in the coffee capsule cannot be effectively used, resulting in waste of the coffee powder and affecting the taste of the coffee, the present invention provides a portable coffee machine that is easy to clean.

[0007] The technical implementation solution of the present invention is: a portable coffee machine that is easy to clean, including a first accommodation chamber, a second accommodation chamber, a mounting ring, and a pressing plate; an inlet pipe is arranged in the first accommodation chamber, and a heater is arranged in the first accommodation chamber; the first accommodation chamber rotates and communicates with the second accommodation chamber, and a pump is arranged in the second accommodation chamber; the mounting ring is detachably connected to the second accommodation chamber; the pressing plate is arranged on the second accommodation chamber; it also includes a fixing ring, a guiding plate, a filter cloth, a resilient strip, a top rod, and a scraping plate; a fixing ring is arranged in front of the first accommodation chamber; a guiding plate for guiding coffee powder is fixedly connected inside the fixing ring; a filter cloth is fixedly connected to the bottom of the fixing ring; a resilient strip is arranged on the filter cloth; a plurality of top rods are fixedly connected to the filter cloth; a plurality of scraping plates are fixedly connected to the bottom of the guiding plate.

[0008] Further, the guiding plate is integrally in a frustum shape.

[0009] Further, a plurality of scraping bars are arranged on all the scraping plates.

[0010] Further, it also includes a cleaning strip; a cleaning strip is fixedly connected to all the scraping plates, and all the cleaning strips are in contact with the surface of the guiding plate.

[0011] Further, it also includes a crushing net and a filter plate; another fixing ring is arranged between the first accommodation chamber and the fixing ring; a crushing net and a filter plate for breaking the surface layer of the coffee capsule are fixedly connected to the bottom of the other fixing ring, and the crushing net is located above the filter plate, and the filtering area of the crushing net is composed of wavy strips.

[0012] Further, the wave troughs of the strips in different directions in the filtering area of the filter plate overlap.

[0013] Further, it also includes a heating barrel; a heating barrel is arranged in the first accommodation chamber, and the upper part of the heating barrel is communicated with the inlet pipe, and a plurality of through holes are opened in the heating barrel; the heating barrel is connected with a conveying pipe for reducing temperature loss, and the conveying pipe is located in the center of the heating barrel and is communicated with the second accommodation chamber.

[0014] Further, the heating barrel is arranged in a multi-layer structure.

[0015] Further, it also includes a connecting ring; the heating barrel and the conveying pipe are rotationally connected, and an electric rotating ring for driving the conveying pipe to rotate is arranged in the first accommodation chamber; a connecting ring for shortening the moving stroke is communicated with the bottom of the conveying pipe, and the connecting ring is attached to the inner wall of the heating barrel, and a plurality of through grooves are opened in the connecting ring, and all the through grooves cooperate with the corresponding through holes.

[0016] Further, the top inside the heating barrel is in an arc design.

[0017] The present invention has the following advantages: By changing the positions of the coffee powder in the upper layer and the lower layer, the coffee powder in the fixed ring can be fully extracted, avoiding waste caused by the backup coffee powder not being fully utilized.

[0018] Through the wavy strips in the crushing net filter area of the present invention, the area of aluminum foil fracturing is increased, and the transfer of the mixture of water and coffee powder becomes smoother. The troughs of the strips in different directions in the filter plate filtering area overlap, increasing the local fracturing force on the aluminum foil, increasing the openings formed by aluminum foil fracturing, increasing the space for the transfer of the mixture of water and coffee powder, and fully utilizing the coffee powder in the coffee capsule to avoid affecting the taste of coffee.

[0019] Due to the multi-layer structure of the heating barrel in the present invention, the temperature loss rate in the central area of the heating barrel is lower than that in the edge area of the heating barrel, enabling the water transferred into the second accommodation chamber to be at an appropriate temperature. When the water is transferred into the second accommodation chamber, the temperature of the water will drop. At this time, by setting the conveying pipeline inside the heating barrel, the temperature of the conveying pipeline itself can be maintained within an appropriate range, reducing the proportion of water temperature drop when the water is transferred into the second accommodation chamber.

[0020] In the present invention, the electric rotating ring in the first accommodation chamber drives the conveying pipeline and the connecting ring to rotate by 45 degrees, enabling the through hole to communicate with the through groove. At this time, the hot water directly enters the through groove from the through hole and then transfers into the conveying pipeline, reducing the travel distance that the hot water needs to flow and avoiding the situation where the long travel distance of the hot water affects its temperature.

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment 1

[0032] An easily cleanable portable coffee machine, as Figures 1 - 5 shown, includes a first accommodation chamber 1, a second accommodation chamber 2, a mounting ring 3 and a pressure plate 4; a water inlet pipeline 1a is arranged in the first accommodation chamber 1, and a heater is arranged in the first accommodation chamber 1; the first accommodation chamber 1 rotates and communicates with the second accommodation chamber 2, and a pump is arranged in the second accommodation chamber 2; the mounting ring 3 is detachably connected to the second accommodation chamber 2; the pressure plate 4 is arranged on the second accommodation chamber 2;

[0033] It further includes a fixing ring 5, a guide plate 6, a filter cloth 7, a resilient strip 8, an ejector rod 9 and a scraper 10; a fixing ring 5 is arranged in front of the first accommodation chamber 1; the guide plate 6 is fixedly connected inside the fixing ring 5; the filter cloth 7 is fixedly connected to the bottom of the fixing ring 5; the resilient strip 8 is arranged on the filter cloth 7; four ejector rods 9 distributed in a ring shape are fixedly connected to the filter cloth 7; four scrapers 10 distributed in a ring shape are fixedly connected to the bottom of the guide plate 6.

[0034] The guide plate 6 is integrally frustum-shaped. By the fact that the guide plate 6 is integrally frustum-shaped, when pushing the coffee powder in the upper center, it is guided to facilitate the transfer of the coffee in the upper center to the lower edge of the fixing ring 5.

[0035] A plurality of scraping bars 10a are provided on all the scraping plates 10. The upper layer of coffee powder covering the lower layer of central coffee powder is intercepted by the scraping bars 10a to avoid affecting the position change of the coffee powder.

[0036] It further includes a cleaning bar 101; all the scraping plates 10 are fixedly connected with a cleaning bar 101 through soft columns, and all the cleaning bars 101 are in contact with the surface of the guide plate 6.

[0037] In the present invention, the pressing plate 4 is replaced accordingly according to whether coffee powder or a coffee capsule is used.

[0038] When the portable coffee machine makes coffee using coffee powder, place the present invention on a flat position and adjust the present invention to Figure 1In the initial state shown, sufficient water is added to the water inlet pipe 1a, and the water is heated by the heater in the first accommodation chamber 1. After that, a specified amount of coffee powder is added into the fixing ring 5, and the coffee powder scatters on the guide plate 6, filter cloth 7, ejector rod 9, scraper 10 and cleaning strip 101. At the same time, the mounting ring 3 is detached from the second accommodation chamber 2, the fixing ring 5 is placed into the mounting ring 3, and the mounting ring 3 is reinstalled onto the second accommodation chamber 2. Then, a collection container is placed below the fixing ring 5. When the heater finishes heating the water, the heater stops operating. Then, the heated water is conveyed into the fixing ring 5 by the pump in the second accommodation chamber 2. The water first transfers from the first accommodation chamber 1 into the second accommodation chamber 2, and then passes through the pressure plate 4 in the second accommodation chamber 2 and transfers into the fixing ring 5. During the water transfer process, the pressure of the water is increased by the pressure plate 4, so that the impact force of the water entering the fixing ring 5 is stronger, thereby enhancing the mixing effect of the water and the coffee powder. At the same time, the water contacts and mixes with the coffee powder on the guide plate 6, filter cloth 7, ejector rod 9, scraper 10 and cleaning strip 101 to form coffee. During the mixing process of the water and the coffee, the coffee in the fixing ring 5 transfers downward under the influence of the water vapor pressure, and the coffee passes through the filter cloth 7 and drops into the collection container. When the heating of the water is completed this time, sufficient water needs to be added to the water inlet pipe 1a again, and the water is heated by the heater in the first accommodation chamber 1 again. During the heating of the water, the toughness strip 8 is manually pushed upward by a tool to push the filter cloth 7 and the ejector rod 9 upward, and the coffee powder in the center of the lower layer moves along. When the ejector rod 9 contacts the scraper 10, the scraper 10 flips upward. When the scraper 10 flips upward, the scraper 10 pushes the coffee powder in the center of the upper layer and transfers the coffee powder in the center of the upper layer to the edge of the fixing ring 5. Since the guide plate 6 is integrally frustum-shaped, it guides the coffee powder in the center of the upper layer during the pushing process, facilitating the transfer of the coffee powder in the center of the upper layer to the edge of the lower layer of the fixing ring 5. Considering that the coffee powder is mixed with water at this time and there is a certain caking phenomenon, which affects the transfer effect of the scraper 10 on the coffee powder, while the scraper 10 flips upward, the scraper 10 pushes the cleaning strip 101 to push the coffee powder on the surface of the guide plate 6 to ensure the effective transfer of the coffee powder by the scraper 10. When the coffee powder in the center of the lower layer moves upward, the original coffee powder in the upper layer will cover it, affecting the transfer of the coffee powder. At this time, the coffee powder in the center of the lower layer is higher than the guide plate 6. During the upward flipping process of the scraper 10, the bottoms of all the scrapers 10 contact each other, so that the upper layer of coffee powder covering the coffee powder in the center of the lower layer is intercepted by the scraping strip 10a, avoiding affecting the position transformation of the coffee powder. When the position transformation of the coffee powder is completed, the positions of the upper and lower layers of coffee powder are correspondingly transformed, so that the coffee powder in the fixing ring 5 can be fully extracted, avoiding waste caused by some coffee powder not being fully used.

[0039] Example 2

[0040] On the basis of Example 1, asFigure 1 and Figure 4 As shown in Figure 4 , it further includes a crushing net 110 and a filter plate 111; Another fixing ring 5 is arranged between the first accommodation chamber 1 and the fixing ring 5; The bottom of the other fixing ring 5 is fixedly connected with a crushing net 110 and a filter plate 111, and the crushing net 110 is located above the filter plate 111. The filtering area of the crushing net 110 is composed of wavy strips.

[0041] The wave troughs of the strips in different directions in the filtering area of the filter plate 111 overlap. The wave troughs of the strips in different directions in the filtering area of the filter plate 111 overlap, so that the local fracturing force on the aluminum foil increases, the openings formed by the fracturing of the aluminum foil increase, the space for the transfer of the mixture of water and coffee powder increases, and the coffee powder in the coffee capsule is fully utilized, avoiding affecting the taste of coffee.

[0042] Considering that the existing portable coffee machines can only use either coffee powder or coffee capsules, which affects the use experience of the portable coffee machines. Before making coffee with coffee capsules in the present invention, the corresponding pressure plate 4 is first replaced on the second accommodation chamber 2. The pressure plate 4 removes the mounting ring 3 and takes away the fixing ring 5 inside the mounting ring 3. A coffee capsule is placed into the other fixing ring 5. At this time, the aluminum foil of the coffee capsule contacts the crushing net 110. After putting the other fixing ring 5 into the mounting ring 3, the mounting ring 3 is installed on the second accommodation chamber 2 again. Then, repeat the above process of making coffee. It should be noted that when making coffee with coffee capsules, the pressure plate 4 is inserted into the coffee capsule, and the heated water is conveyed into the coffee capsule through the pressure plate 4 for mixing. When squeezing the coffee powder in the coffee capsule, the aluminum foil on the coffee capsule is pressed on the crushing net 110. The strips in the filtering area of the crushing net 110 fracture the aluminum foil on the coffee capsule, increasing the flow area of water in the coffee capsule. Through the wavy strips in the filtering area of the crushing net 110, the fractured area of the aluminum foil increases, and the transfer of the mixture of water and coffee powder becomes smoother. The wave troughs of the strips in different directions in the filtering area of the filter plate 111 overlap, so that the local fracturing force on the aluminum foil increases, the openings formed by the fracturing of the aluminum foil increase, the space for the transfer of the mixture of water and coffee powder increases, and the coffee powder in the coffee capsule is fully utilized, avoiding affecting the taste of coffee.

[0043] It should be noted that when making coffee with coffee capsules, the pressure plate 4 is provided with spikes for piercing the coffee capsules.

[0044] Embodiment 3

[0045] On the basis of Embodiment 2, as Figures 5 - 8As shown in the figure, it further includes a heating barrel 201. The heating barrel 201 is arranged in the first accommodation chamber 1, and the upper part of the heating barrel 201 is communicated with the water inlet pipe 1a. Four through holes 201a are opened in the heating barrel 201. The heating barrel 201 is connected with a conveying pipe 202, and the conveying pipe 202 is located at the center of the heating barrel 201. The conveying pipe 202 is communicated with the second accommodation chamber 2.

[0046] Preferably, the heating barrel 201 is arranged in a multi-layer structure to keep the water at the center of the heating barrel 201 warm and prevent the temperature of the heated water from dropping rapidly.

[0047] It further includes a connecting ring 203. The heating barrel 201 and the conveying pipe 202 are rotatably connected. An electric rotating ring is arranged in the first accommodation chamber 1. The bottom of the conveying pipe 202 is communicated with the connecting ring 203, and the connecting ring 203 is attached to the inner wall of the heating barrel 201. Four through slots 203a are opened in the connecting ring 203, and all the through slots 203a cooperate with the corresponding through holes 201a.

[0048] The top inside the heating barrel 201 is designed in an arc shape to facilitate the flow of water and avoid residue.

[0049] When heating water, usually the metal pipe inside the coffee machine is heated to raise the temperature of the water in the metal pipe. Since the metal pipe does not have a heat preservation function, after the temperature is raised, the temperature of the metal pipe also drops, making the water unable to be mixed with coffee powder at a suitable temperature. The insufficient water temperature causes the coffee powder not to be completely dissolved, and the undissolved coffee powder mixes into the coffee, affecting the taste. By conveying the water into the heating barrel 201 for heating, when the water enters the heating barrel 201, it flows in the flowing mode as shown in the figure. After the temperature of the heating barrel 201 rises, the temperature of the edge area of the heating barrel 201 will drop relatively fast, while the temperature of the central area of the heating barrel 201 is under the heat preservation effect of the multi-layer structure of the heating barrel 201, and the temperature drop rate is lower than that of the edge area of the heating barrel 201, making the water transferred to the second accommodation chamber 2 at a suitable temperature. When the water is transferred to the second accommodation chamber 2, the temperature of the water will drop. At this time, by setting the conveying pipe 202 inside the heating barrel 201, the temperature of the conveying pipe 202 itself can be kept within a suitable range, reducing the proportion of the water temperature drop when the water is transferred to the second accommodation chamber 2. Figure 8 As shown in the figure, when flowing, after the temperature of the heating barrel 201 rises, the temperature of the edge area of the heating barrel 201 will drop relatively fast, while the temperature of the central area of the heating barrel 201 is under the heat preservation effect of the multi-layer structure of the heating barrel 201, and the temperature drop rate is lower than that of the edge area of the heating barrel 201, making the water transferred to the second accommodation chamber 2 at a suitable temperature. When the water is transferred to the second accommodation chamber 2, the temperature of the water will drop. At this time, by setting the conveying pipe 202 inside the heating barrel 201, the temperature of the conveying pipe 202 itself can be kept within a suitable range, reducing the proportion of the water temperature drop when the water is transferred to the second accommodation chamber 2.

[0050] It should be noted that when adding water subsequently, the newly added water will push the water that has been heated to the center of the heating barrel 201, reducing the heating time of the subsequent water and accelerating the production of coffee.

[0051] Considering that the portable coffee machine may run out of power, in this case, the user will directly add hot water into the portable coffee machine to make coffee. At this time, the heating barrel 201 is not heated. After the hot water passes through the multi-layer structure of the heating barrel 201, the temperature of the hot water is absorbed by the metal pipeline, and the temperature of the hot water is affected, dropping out of the appropriate temperature range, which affects the production of coffee powder. At this time, the electric rotating ring in the first accommodation chamber 1 drives the conveying pipeline 202 and the connecting ring 203 to rotate 45 degrees, so that the through hole 201a is communicated with the through groove 203a. At this time, the hot water directly enters the through groove 203a from the through hole 201a and is transferred into the conveying pipeline 202 at the same time, reducing the travel distance that the hot water needs to flow, and avoiding the too long travel distance of the hot water, resulting in the influence on the temperature of the hot water.

[0052] It should be understood that this embodiment is only used to illustrate the present invention and not to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of this application.
