[0002] A beverage machine is a machine that allows users to brew beverages, including tea, coffee, fruit juice, etc. Beverage machines generally include a push rod device and a piercing device. By operating the push rod device, the piercing device pierces the beverage capsule containing tea, coffee, etc., and hot water is poured in for brewing. Specifically, the piercing device includes a movable component and a fixed component, and the push rod device can drive the movable component to move forward and backward relative to the fixed component.

[0003] At present, the push rod device generally includes a handle and a push rod mechanism. In the specific operation process, the handle can drive the push rod mechanism to move, and drive the movable component to move forward and backward. However, the push rod mechanism in the prior art is often complex in structure, and in the process of the push rod device driving the movable component to move forward and backward, it is easy to cause the movable component to swing too much, affecting the puncturing action of the puncturing device. In view of this, the inventors specially proposed this application after studying the existing technology. Summary of the invention

[0004] The present invention provides a push rod device and a beverage machine, aiming to improve the problem that the push rod device in the prior art easily causes the piercing device to swing too much.

[0005] In order to solve the above technical problems, the present invention provides a push rod device for driving a movable component to move forward and backward, and the push rod device comprises: a support seat, which comprises a first hinge part and a second hinge part, the first hinge part is higher than the second hinge part, and the movable component can be supported on the support seat to move forward and backward; a handle, which comprises a third hinge part and a fourth hinge part, and the third hinge part is hinged to the first hinge part; a push rod mechanism, which comprises a first hinge assembly having a first hinge rod, a second hinge assembly having a second hinge rod, and a third hinge assembly having a third hinge rod; the second hinge rod comprises a horizontally arranged A horizontal section, and an inclined section inclined at the horizontal section, a first hinge axis is arranged at the end of the horizontal section, a second hinge axis is arranged at the end of the inclined section, and a third hinge axis is arranged at the connection between the horizontal section and the inclined section; the two ends of the first hinge rod are respectively hinged to the fourth hinge part and the second hinge axis; the two ends of the third hinge rod are respectively hinged to the third hinge axis and the movable component; the handle is hinged upward relative to the support seat to drive the movable component to move backward; the handle is hinged downward relative to the support seat to drive the movable component to move forward.

[0006] As a further optimization, the third hinge shaft is provided with a hinge hole M, the cross section of which has an A end and a B end; the third hinge rod is provided with a hinge shaft N adapted to the hinge hole M, and the hinge shaft N can move back and forth between the A end and the B end.

[0007] As a further optimization, the horizontal section is provided with a movable channel, and the second hinge assembly includes an elastic member which is arranged in the movable channel and has one end extending through the horizontal section and abutting against the hinge axis N.

[0008] As a further optimization, the handle is hinged downward relative to the support base, which can drive the second hinged rod to hinge downward, so that the horizontal section is tilted downward relative to the support base.

[0009] As a further optimization, the handle drives the movable component to move to a maximum distance from the second hinged rod, and an angle between the horizontal section and a horizontal line of the support seat is 1°~2°.

[0010] As a further optimization, the third hinged rod is provided with a support portion extending downward, and the handle drives the movable assembly to move forward, which can drive the third hinged rod to swing downward, so that the support portion is supported on the support seat.

[0011] As a further optimization, the support seat is provided with a slide groove in the front-to-back direction, and the movable component includes a guide seat arranged on the movable component, and the guide seat is provided with a sliding part adapted to the slide groove.

[0012] The present application further provides a beverage machine, comprising a push rod device and a piercing device, the piercing device comprising a movable component and a fixed component, a beverage capsule can be accommodated between the movable component and the fixed component, the push rod device can drive the movable component away from and close to the fixed component, and the push rod device is any one of the push rod devices described above.

[0013] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0014] The push rod device of the present invention has the beneficial effect of reducing the swing amplitude of the movable assembly. Specifically, when the handle is hinged downward relative to the support seat, it will drive the first hinged rod to hinge downward, and drive the second hinged rod to hinge downward, and at the same time, the angle between the second hinged rod and the third hinged rod will increase. Since one end of the second hinged rod is hinged on the support seat, the third hinged rod will be forced to move forward relative to the support seat, and the third hinged rod moving forward can drive the movable assembly to move forward. Conversely, when the handle is hinged upward relative to the support seat, it will drive the first hinged rod to hinge upward, and drive the second hinged rod to hinge upward, and at the same time, the angle between the second hinged rod and the third hinged rod will decrease. Since one end of the second hinged rod is hinged on the support seat, the third hinged rod will be forced to move backward relative to the support seat, and the third hinged rod moving backward can drive the movable assembly to move backward. In this case, since one end of the first hinge rod is hinged on the second hinge shaft, and one end of the third hinge rod is hinged on the third hinge shaft; since the second hinge shaft is located at the end of the inclined section, and the third hinge shaft is located at the connection between the horizontal section and the inclined section, the third hinge shaft is higher than the second hinge shaft. Obviously, the higher the hinge point between the third hinge shaft and the first hinge rod is, the greater the angle between the third hinge shaft and the support seat. The forward and backward movement of the movable component is realized by the swing of the third hinge rod, so the greater the angle between the third hinge shaft and the support seat, the greater the swing amplitude of the movable component. The movable component can only move forward and backward along the support seat, so a movable component with a larger swing amplitude will cause a greater force between the movable component and the support seat, which is not conducive to the forward and backward movement of the movable component. Therefore, the push rod device in this case can reduce the swing amplitude of the movable component by allowing the first hinge rod to be hinged on the second hinge shaft and the third hinge rod to be hinged on the third hinge shaft, thereby allowing the movable component to move forward and backward more smoothly. In addition, the inclined section is tilted, and the first hinge rod is hinged on the second hinge shaft, so that the force arm driving the second hinge rod to swing and hinge can be lengthened, so that the user can use less driving force to act on the handle, thereby driving the forward and backward movement of the movable component. Through the above technical solution, the push rod device of this case has the beneficial effect of reducing the swing amplitude of the movable component, making the forward and backward movement of the movable component smoother. At the same time, it can also allow the user to use less force to achieve the forward and backward movement of the movable component. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0029] Depend on Figures 1 to 3As shown, in this embodiment, a push rod device is used to drive a movable component 12 to move forward and backward, and the push rod device includes: a support seat 2, which includes a first hinge part 3 and a second hinge part 4, the first hinge part 3 is higher than the second hinge part 4, and the movable component 12 can be supported on the support seat 2 to move forward and backward; a handle 1, which includes a third hinge part 5 and a fourth hinge part 6, and the third hinge part 5 is hinged to the first hinge part 3; a push rod mechanism 10, which includes a first hinge assembly 7 with a first hinge rod 16, a second hinge assembly 8 with a second hinge rod 17, and a third hinge assembly 9 with a third hinge rod 18; the second hinge rod 17 includes a horizontally arranged A horizontal section 28 is disposed, and an inclined section 29 is inclinedly disposed at the horizontal section 28, a first hinge axis 25 is disposed at the end of the horizontal section 28, a second hinge axis 26 is disposed at the end of the inclined section 29, and a third hinge axis 27 is disposed at the connection between the horizontal section 28 and the inclined section 29; both ends of the first hinge rod 16 are respectively hinged to the fourth hinge portion 6 and the second hinge axis 26; both ends of the third hinge rod 18 are respectively hinged to the third hinge axis 27 and the movable component 12; the handle 1 is hinged upward relative to the support seat 2, and can drive the movable component 12 to move backward; the handle 1 is hinged downward relative to the support seat 2, and can drive the movable component 12 to move forward.

[0030] Specifically, Figure 4 and Figure 5 As shown, Figure 4 The middle handle 1 is in a closed state, at which time the movable component 12 is at the front end and abuts against the fixed component 13 . Figure 5The middle handle 1 is in the open state, at which time the movable assembly 12 is at the rear end and away from the fixed assembly 13. When the handle 1 is hinged downward relative to the support base 2, it will drive the first hinge rod 16 to hinge downward, and drive the second hinge rod 17 to hinge downward, and at the same time, the angle between the second hinge rod 17 and the third hinge rod 18 will increase. Since one end of the second hinge rod 17 is hinged on the support base 2, it will force the third hinge rod 18 to move forward relative to the support base 2, and the third hinge rod 18 moving forward can drive the movable assembly 12 to move forward. On the contrary, when the handle 1 is hinged upward relative to the support base 2, the first hinge rod 16 is driven to be hinged upward, and the second hinge rod 17 is driven to be hinged upward, and the angle between the second hinge rod 17 and the third hinge rod 18 is reduced. Since one end of the second hinge rod 17 is hinged on the support base 2, the third hinge rod 18 is forced to move backward relative to the support base 2, and the third hinge rod 18 moving backward can drive the movable assembly 12 to move backward. In this embodiment, since one end of the first hinge rod 16 is hinged on the second hinge shaft 26, and one end of the third hinge rod 18 is hinged on the third hinge shaft 27; since the second hinge shaft 26 is located at the end of the inclined section 29, and the third hinge shaft 27 is located at the connection between the horizontal section 28 and the inclined section 29, the third hinge shaft 27 is higher than the second hinge shaft 26. Obviously, the higher the hinge point between the third hinge shaft 27 and the first hinge rod 16, the larger the angle between the third hinge shaft 27 and the support seat 2. The forward and backward movement of the movable component 12 is realized by the swing of the third hinge rod 18. Therefore, the larger the angle between the third hinge shaft 27 and the support seat 2, the larger the swing amplitude of the movable component 12. The movable component 12 can only move forward and backward along the support seat 2. Therefore, a movable component 12 with a larger swing amplitude will cause a larger force between the movable component 12 and the support seat 2, which is not conducive to the forward and backward movement of the movable component 12. Therefore, the push rod device in this embodiment can reduce the swing amplitude of the movable component 12 by allowing the first hinge rod 16 to be hinged on the second hinge shaft 26 and the third hinge rod 18 to be hinged on the third hinge shaft 27, thereby allowing the movable component 12 to move forward and backward more smoothly. In addition, the inclined section 29 in this embodiment and the first hinge rod 16 being hinged on the second hinge shaft 26 can lengthen the force arm driving the second hinge rod 17 to swing and hinge, allowing the user to use less driving force on the handle 1, thereby driving the movable component 12 to move forward and backward.

[0031] Depend on Figure 6As shown, in this embodiment, the third hinge shaft 27 is provided with a hinge hole M22, and the cross section of the hinge hole has an A end and a B end; the third hinge rod 18 is provided with a hinge shaft N23 adapted to the hinge hole M22, and the hinge shaft N23 can move back and forth between the A end and the B end. Specifically, when the second hinge rod 17 is driven to swing by the first hinge rod 16, the second hinge rod 17 and the third hinge rod 18 will be hinged, and the setting of the hinge hole M22 allows the hinge shaft N23 to move between the A end and the B end, further reducing the swinging action of the third hinge rod 18 that is unrelated to the forward and backward movement of the driving movable assembly 12.

[0032] Depend on Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, the horizontal section 28 is provided with an active channel 30, and the second hinge assembly 8 includes an elastic member 21 disposed in the active channel 30, and one end of which passes through the horizontal section 28 and abuts against the hinge axis N23. Specifically, the elastic member 21 is in a compressed state, which can increase the assembly stability of the second hinge rod 17 and the third hinge rod 18, and will not allow the hinge axis N23 to move freely between the A end and the B end. At the same time, Figure 4 As shown, the handle 1 is hinged downward relative to the support base 2, which can drive the second hinge rod 17 to hinge downward, so that the horizontal section 28 is tilted downward relative to the support base 2. That is, at this time, the second hinge rod 17 and the third hinge rod 18 are arranged in a "V" shape. At this time, even if the force acting on the handle 1 is released, the elastic member 21 can ensure that the second hinge assembly 8 has a tendency to drive the third hinge rod 18 to move forward, so as to ensure that the movable assembly 12 abuts against the fixed assembly 13. Figure 4 As shown, in this embodiment, the handle 1 drives the movable assembly 12 to move to the maximum distance from the second hinge rod 17, and the angle J between the horizontal section 28 and the horizontal line of the support seat 2 is 1°~2°. In this embodiment, the second hinge assembly 8 also has a guide rod 20 configured in the movable channel 30, wherein the elastic member 21 is a spring, and the spring is sleeved on the guide rod 20. In another embodiment, the second hinge assembly 8 can abandon the guide rod 20, and the elastic member 21 can be an elastic body made of rubber, such as a rubber elastic sleeve, or an elastic steel sheet made of a steel sheet.

[0033] Depend on Figure 3 As shown, in this embodiment, the first hinge assembly 7 further includes a connecting rod cover 19 , and the connecting rod cover 19 is disposed on the first hinge rod 16 , which can ensure the stability of the cooperation between the first hinge rod 16 and the second hinge rod 17 .

[0034] Depend on Figure 3 and Figure 4As shown, in this embodiment, the third hinge rod 18 is provided with a support portion 24 extending downward, and the handle 1 drives the movable assembly 12 to move forward, which can drive the third hinge rod 18 to swing downward, so that the support portion 24 is supported on the support seat 2. Specifically, the support portion 24 is a protrusion provided on the third hinge rod 18, and the support portion 24 can limit the maximum downward swing of the third hinge rod 18.

[0035] Depend on Figure 2 and Figure 3 As shown, in this embodiment, the support seat 2 is provided with a slide groove 15 in the front-to-back direction, and the movable assembly 12 includes a guide seat 11 disposed on the movable assembly 12, and the guide seat 11 is provided with a sliding portion 31 adapted to the slide groove 15. Specifically, the sliding portion 31 is a slider disposed on the guide seat 11, and the cooperation between the slide groove 15 and the sliding portion 31 can improve the smoothness of the movable assembly 12 moving forward and backward along the slide groove 15.

[0036] Through this embodiment, the push rod device of this case has the beneficial effect of reducing the swing amplitude of the movable component 12, making the movable component 12 move forward and backward more smoothly. At the same time, it also allows the user to achieve the forward and backward movement of the movable component 12 with less force.

[0037] This embodiment further provides a beverage machine, including a push rod device and a piercing device 14, the piercing device 14 includes a movable component 12 and a fixed component 13, a beverage capsule can be accommodated between the movable component 12 and the fixed component 13, the push rod device can drive the movable component 12 away from and close to the fixed component 13, and the push rod device is the push rod device in the above embodiment. Specifically, the movable component 12 can pierce the beverage capsule when it moves forward, so that the beverage machine can brew the beverage capsule, wherein the beverage capsule is a capsule containing tea, coffee, or juice powder. The specific brewing working principle of the beverage machine belongs to the prior art and will not be repeated here. Compared with the prior art, the beverage machine in this case can move more stably when the movable component 12 is driven to move forward and backward by the handle 1.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
