Description

Technical Field

[0001] The present disclosure relates to the field of coffee technology, and in particular to a double-handled hand-pressing mechanism and a coffee machine. Background Art

[0002] At present, with the improvement of consumers' living standards, drinking coffee has become a common leisure activity for consumers. In order to save the coffee making process, most manufacturers have produced hand-pressed coffee machines. Using coffee machines to make coffee is convenient to shorten time and ensure the quality of coffee.

[0003] For example, Chinese patent document CN220109565U discloses a hand-pressed coffee machine, comprising a base, a support frame fixedly mounted on the top of the base, a pressing handle rotatably mounted inside the support frame, an extraction assembly fixedly mounted on the lower end of the side of the support frame, a drive frame fixedly mounted on the upper end of the side of the support frame, a connecting sleeve fixedly mounted on the side of the drive frame, a movable central shaft movably mounted inside the connecting sleeve, and a double ball head structure movably mounted on the bottom of the movable central shaft.

[0004] However, the design of the above-mentioned hand-pressed coffee machine has the following problems:

[0005] Although the above-mentioned hand-pressed coffee machine makes the force on the coffee more even by correcting the offset between the movable central axis and the movable plug, the hand-pressed coffee machine requires a lot of strength from the barista when using the coffee machine, which is not conducive to coffee making. At the same time, when the single handle is pressed down on the coffee machine, the force will be biased to one side, making it easy for the base to tip over to one side, causing the entire coffee machine to tip over.

Connecting rod push handle 350; a pushing slide cavity 3110 is opened in the pushing cylinder 310, and the pushing piston 330 is slidably arranged in the pushing slide cavity 3110; the push rod 320 is arranged between the filter press cylinder 100 and the pushing cylinder 310, and the two ends of the push rod 320 are respectively connected to the filter press piston 120 and the pushing piston 330; the first connecting rod push handle 340 and the second connecting rod push handle 350 are respectively rotatably arranged on the pushing cylinder 310, and the pushing end of the first connecting rod push handle 340 and the pushing end of the second connecting rod push handle 350 are jointly connected to the pushing piston 330, and the handle end of the first connecting rod push handle 340 and the handle end of the second connecting rod push handle 350 are symmetrically arranged on both sides of the pushing cylinder 310.

[0035] It can be understood that by opening a pushing slide cavity 3110 in the pushing cylinder 310, the pushing piston 330 is arranged in the pushing slide cavity 3110, and the push rod 320 is arranged between the filter press cylinder 100 and the pushing cylinder 310, and the two ends of the push rod 320 are respectively connected to the filter press piston 120 and the pushing piston 330, so that the pushing cylinder 310 and the filter press cylinder 100 are connected through the push rod 320, and the push rod 320 can push the pushing piston 330 through the pushing slide cavity 3110, so that the filter press piston 120 of the filter press cylinder 100 works; at the same time, the first connecting rod push handle 340 and the second connecting rod push handle 350 are respectively rotatably arranged on the pushing cylinder 310, The pushing end of the first connecting rod push handle 340 and the pushing end of the second connecting rod push handle 350 are jointly connected to the pushing piston 330, so that when using the double-handle hand pressing mechanism 10, the first connecting rod push handle 340 and the second connecting rod push handle 350 are pressed down or lifted at the same time, so that the push rod 320 can be pushed smoothly, and the pushing cylinder 310 can be placed stably on the desktop, so that when making coffee, the first connecting rod push handle 340 and the second connecting rod push handle 350 are pressed down by both hands, so that the user does not need to expend much effort to press down the coffee machine, and uses both hands to operate at the same time, avoiding the force being biased to one side and preventing the base from tipping forward or backward.

[0036] It can be understood that, compared with the hand-pressed coffee machine in the prior art, the above-mentioned double-handle hand-pressed mechanism 10, by arranging the pushing end of the first connecting rod push handle 340 and the pushing end of the second connecting rod push handle 350 to be connected to the pushing piston 330, allows people to brew coffee by pressing down or lifting the first connecting rod push handle 340 and the second connecting rod push handle 350 at the same time, which requires less effort to push the coffee machine to work. At the same time, because the first connecting rod push handle 340 and the second connecting rod push handle 350 are pressed down on both sides at the same time, the coffee machine as a whole remains balanced and will not tilt to the other side or overturn.

[0037] like Figure 1 As shown, specifically, the first connecting rod push handle 340 includes a first handle 3420 and a first lever arm 3410, and the second connecting rod push handle 350 includes a second handle 3520 and a second lever arm 3510; the first handle 3420 and the second handle 3520 are symmetrically arranged on both sides of the pushing cylinder 310; the first end of the first handle 3420 and the first end of the second handle 3520 are fitted in the top port of the pushing slide cavity 3110, and are respectively rotatably connected to the cavity wall of the pushing slide cavity 3110; the first end of the first lever arm 3410 is rotatably connected to the first end of the first handle 3420, the first end of the second lever arm 3510 is rotatably connected to the first end of the second handle 3520, the second end of the first lever arm 3410 and the second end of the second lever arm 3510 are fitted in the pushing slide cavity 3110, and are jointly connected to the pushing piston 330. It can be understood that by arranging the first handle 3420 and the second handle 3520 on both sides of the pushing cylinder 310, the first end of the first handle 3420 and the first end of the second handle 3520 are fitted in the top port of the pushing slide cavity 3110, and the cavity wall of the pushing slide cavity 3110 is rotatably connected, so that when the first handle 3420 and the second handle 3520 are pressed down or lifted, the first handle 3420 and the second handle 3520 can be rotated at the same time on the cavity wall of the pushing slide cavity 3110. At the same time, because the first end of the first handle 3420 is connected to the first The first end of the lever arm 3410 and the first end of the second handle 3520 are connected to the first end of the second lever arm 3510, and the other ends of the first lever arm 3410 and the second lever arm 3510 are fitted in the pushing slide cavity 3110 and connected to the pushing piston 330, so that when the first handle 3420 and the second handle 3520 are pushed, the first lever arm 3410 and the second lever arm 3510 are driven to move, so that the pushing piston 330 moves downward, driving the downward movement of the push rod 320, making it more convenient and quick to push the pushing piston 330.

[0038] like Figure 1As shown, specifically, the first lever arm 3410 and the second lever arm 3510 are respectively provided with oppositely arranged avoidance arc openings 341a, and each avoidance arc opening 341a is close to the top port of the push slide cavity 3110. It can be understood that when the first handle 3420 and the second handle 3520 are pulled upward, the opening angle of the first lever arm 3410 and the second lever arm 3510 is reduced, and the avoidance arc opening 341a is provided on the first lever arm 3410 and the second lever arm 3510, so that when the opening angle of the first lever arm 3410 and the second lever arm 3510 is reduced, the first lever arm 3410 and the first handle 3420 can avoid each other, and the second lever arm 3510 and the second handle 3520 can avoid each other.

[0039] like Figure 1 As shown, further, the pushing piston 330 includes a plug head 3310 and a connecting shaft 3320, and a connecting cavity 331a is opened in the plug head 3310; the pushing end of the first connecting rod push handle 340 and the pushing end of the second connecting rod push handle 350 are fitted in the connecting cavity 331a, and the shaft body of the connecting shaft 3320 passes through the pushing end of the first connecting rod push handle 340 and the pushing end of the second connecting rod push handle 350, and the two ends of the connecting shaft 3320 are respectively connected to the cavity wall of the connecting cavity 331a. It can be understood that the pushing ends of the first connecting rod push handle 340 and the second connecting rod push handle 350 are arranged in the connecting cavity 331a, and at the same time, the pushing ends of the first connecting rod push handle 340 and the second connecting rod push handle 350 are connected to the cavity wall of the connecting cavity 331a through the axial body of the connecting shaft 3320, so that when the first connecting rod push handle 340 and the second connecting rod push handle 350 are pushed downward at the same time, the first connecting rod push handle 340 and the second connecting rod push handle 350 are always kept from separating due to the different magnitudes of their respective forces, so that the first connecting rod push handle 340 and the second connecting rod push handle 350 are more firmly placed on the pushing piston 330, and will not shake in the pushing piston 330 due to excessive force.

[0040] like Figure 1As shown, specifically, a limiting plugging cover 360 is provided at the bottom of the pushing slide cavity 3110, a guiding through hole 3610 is opened on the limiting plugging cover 360, and the push rod 320 slides through the guiding through hole 3610; the first end of the push rod 320 extends into the pushing slide cavity 3110 and is connected to the pushing piston 330; the second end of the push rod 320 extends into the guiding slide cavity 110 and is connected to the filter press piston 120. It can be understood that the limiting plug cover 360 is set at the bottom of the pushing slide cavity 3110, and the limiting plug cover 360 is provided with a guide hole 3610, and the push rod 320 is penetrated by the guide hole 3610, so that when the first connecting rod push handle 340 and the second connecting rod push handle 350 are pushed, the guide hole 3610 of the pushing slide cavity 3110 will enable the push rod 320 to maintain the correct movement path during the sliding process, prevent the push rod 320 from being offset or tilted, and ensure the stability of the double-handle hand pressing mechanism 10. At the same time, the second end of the push rod 320 is connected to the filter press piston 120, so that the push rod 320 can transmit the pressure of the pushing piston 330 to the filter press piston 120.

[0041] like Figure 2 As shown, in one embodiment, the push rod 320 includes a sliding rod body 3210 and a ball head body 3220; the sliding rod body 3210 is slidably arranged in the guide through hole 3610, and the first end of the sliding rod body 3210 is screwed to the pushing piston 330; the ball head body 3220 is arranged at the second end of the sliding rod body 3210, and the ball head body 3220 is rotatably connected to the filter press piston 120. It can be understood that by screwing the pushing piston 330 to the first end of the sliding rod body 3210, the ball head body 3220 is arranged at the second end of the sliding rod body 3210, and the filter press piston 120 is rotatably connected to the ball head body 3220, when the pushing piston 330 is subjected to pressure, the sliding rod body 3210 is driven to move downward, and at the same time, the ball head body 3220 is arranged at the second end of the sliding rod body 3210 and connected to the filter press piston 120, so that the ball head body 3220 squeezes the filter press piston 120 more softly and smoothly.

[0042] Combination Figure 1 and Figure 2As shown, in one embodiment, the filter press piston 120 is provided with a water injection port 1210, a universal rotating chamber 1220 and a connecting port 1230 which are connected in sequence; the water injection port 1210 is close to the pushing cylinder 310, and the ball head body 3220 is clamped in the water injection port 1210 or accommodated and sealed in the universal rotating chamber 1220; the connecting port 1230 is close to and connected to the opening of the filter bowl 200. It can be understood that by setting the ball head body 3220 to be stuck in the water injection port 1210 or to be accommodated and sealed in the universal rotating chamber 1220, when the first connecting rod push handle 340 and the second connecting rod push handle 350 are pressed down, the push rod 320 is driven downward, and the ball head body 3220 of the push rod 320 will be sealed in the universal rotating chamber 1220, so that the liquid will not flow into the filter bowl 200. When the ball head body 3220 is stuck in the water injection port 1210, the liquid will flow into the filter press cylinder 100.

[0043] like Figure 2 As shown, specifically, the guide slide cavity 110 includes a slide plug cavity 1110, a water filling cavity 1120 and an embedded bowl port 1130 which are connected in sequence; the slide plug cavity 1110 is close to the push assembly 300, the filter pressing piston 120 is slidably arranged in the slide plug cavity 1110, and the opening of the filter bowl 200 is embedded in the slide plug cavity 1110; the water filling cavity 1120 and the embedded bowl port 1130 are separated by the water dividing net 210. It can be understood that the filter pressing piston 120 is slidably arranged in the slide plug cavity 1110, so that the filter pressing piston 120 moves smoothly in the slide plug cavity 1110, and at the same time, the opening of the filter bowl 200 is embedded in the slide plug cavity 1110 and the water dividing net 210 separates the water filling cavity 1120 from the embedded bowl port 1130, so that when water enters the water filling cavity 1120, it can be more evenly distributed in the filter bowl 200 through the water dividing net 210.

[0044] Combination Figure 3 and Figure 4 As shown, the double-handle hand-pressing mechanism 10 further includes a pressure gauge 400, which is arranged outside the filter press cylinder 100; the pressure sensing end of the pressure gauge 400 is connected to the water filling chamber 1120. It can be understood that the pressure gauge 400 is arranged outside the filter press cylinder 100, and the water filling chamber 1120 is connected to the pressure sensing end of the pressure gauge 400, so that when people use the double-handle hand-pressing mechanism 10, they can be connected to the water filling chamber 1120 through the pressure gauge 400, and the pressure gauge 400 can sense the pressure of the water filling chamber 1120 and convert it into a corresponding pressure value, so that the operator can try to understand the pressure of the filter press cylinder 100, and the operator can adjust the downward pressure of the first connecting rod push handle 340 and the second connecting rod push handle 350 according to the pressure value displayed on the pressure gauge 400, so as to control the pressure of the filter press cylinder 100.

[0045] Combination Figure 1 and Figure 3As shown, the present disclosure also provides a coffee machine, including the double-rod hand-pressing mechanism described in any of the above embodiments. It can be understood that by applying the double-rod hand-pressing mechanism of the present disclosure to coffee, the first connecting rod push handle 340 and the second connecting rod push handle 350 are respectively rotatably arranged on the pushing cylinder 310, the pushing end of the first connecting rod push handle 340 and the pushing end of the second connecting rod push handle 350 are commonly connected to the pushing piston 330, and the handle end of the first connecting rod push handle 340 and the handle end of the second connecting rod push handle 350 are symmetrically arranged on both sides of the pushing cylinder 310, so that when the user presses down the first connecting rod push handle 340 and the second connecting rod push handle 350 with both hands when making coffee, the user consumes less effort, and uses both hands to press down at the same time, avoiding the situation where the force is biased to one side and causes the coffee machine to tip over as a whole.

[0046] Compared with the prior art, the present invention has at least the following advantages:

[0047] 1) A pushing slide cavity 3110 is provided in the pushing cylinder 310, a pushing piston 330 is arranged in the pushing slide cavity 3110, and a push rod 320 is arranged between the filter press cylinder 100 and the pushing cylinder 310, and the push rod 320 is arranged between the filter press cylinder 100 and the pushing cylinder 310, and both ends of the push rod 320 are respectively connected to the filter press piston 120 and the pushing piston 330, so that the pushing cylinder 310 and the filter press cylinder 100 are connected through the push rod 320, and the push rod 320 can push the pushing piston 330 through the pushing slide cavity 3110, so that the filter press piston 120 of the filter press cylinder 100 works; at the same time, the first connecting rod push handle 340 and the second connecting rod push handle 350 are respectively rotated The pushing end of the first connecting rod push handle 340 and the pushing end of the second connecting rod push handle 350 are arranged on the pushing cylinder 310, and are connected to the pushing piston 330 together, so that when using the double-handle hand pressing mechanism 10, the first connecting rod push handle 340 and the second connecting rod push handle 350 are pressed down or lifted at the same time, so that the push rod 320 can be pushed stably, and the pushing cylinder 310 can be placed stably on the desktop, so that when making coffee, the first connecting rod push handle 340 and the second connecting rod push handle 350 are pressed down by both hands, so that the user does not need to expend much effort to press down the coffee machine, and uses both hands to operate at the same time, avoiding the force being biased to one side and avoiding the situation where the base will not tip forward or backward.

[0048] 2) Compared with the hand-pressed coffee machine in the prior art, the above-mentioned double-handle hand-pressed mechanism 10, by arranging the pushing end of the first connecting rod push handle 340 and the pushing end of the second connecting rod push handle 350 to be connected to the pushing piston 330, when people are brewing coffee, the user presses down or lifts the first connecting rod push handle 340 and the second connecting rod push handle 350 at the same time, and only a small amount of effort is needed to push the coffee machine to work. At the same time, because the first connecting rod push handle 340 and the second connecting rod push handle 350 are pressed down on both sides at the same time, the coffee machine as a whole remains balanced and will not tilt to the other side or overturn.

[0049] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the patent of the present disclosure shall be based on the attached claims.
