[0027] The present application will be further described in detail with reference to the embodiments given in the accompanying drawings.

[0028] As Figures 1 to 7As shown, the buckle type coffee pot provided by the present application comprises an upper pot body 1, a lower pot body 2, an upper pot body connecting seat 3, a lower pot body connecting seat 4, a handle 5, two movable buckles 6a / 6b and a driving mechanism 7. The upper pot body connecting seat 3 is arranged at the lower end of the upper pot body 1, the lower pot body connecting seat 4 is arranged at the upper end of the lower pot body 2, the lower end of the upper pot body connecting seat 3 is provided with a downwardly open receiving part 301, the outer side of the upper end of the lower pot body connecting seat 4 is provided with an annular engaging part 41, and the annular engaging part 41 extends into the receiving part 301. The two movable buckles 6a / 6b are arranged on the two sides of the upper pot body connecting seat 3, one end of the two movable buckles 6a / 6b is pivoted to the same side of the upper pot body connecting seat 3, and the other end of the two movable buckles 6a / 6b is arranged as an opening and closing end and can be relatively opened or closed. When the opening and closing ends of the two movable buckles 6a / 6b are relatively closed, the annular engaging part 41 is stopped by the two movable buckles 6a / 6b and cannot be separated from the receiving part 301, thereby connecting the upper pot body connecting seat 3 and the lower pot body connecting seat 4 together, so as to realize the connection of the upper pot body 1 and the lower pot body 2. When the opening and closing ends of the two movable buckles 6a / 6b are relatively opened, the two movable buckles 6a / 6b are separated from the stop of the annular engaging part 41, so that the annular engaging part 41 can be separated from the receiving part 301, thereby the upper pot body connecting seat 3 and the lower pot body connecting seat 4 can be separated from each other, so as to realize the opening of the upper pot body 1 and the lower pot body 2. The handle 5 is arranged on the side of the upper pot body 1 corresponding to the opening and closing ends of the two movable buckles 6a / 6b, the driving mechanism 7 is arranged on the handle 5, and the driving mechanism 7 can drive the opening and closing ends of the two movable buckles 6a / 6b to be relatively closed and locked, or can drive the opening and closing ends of the two movable buckles 6a / 6b to be relatively opened.

[0029] In a preferred embodiment of the present invention, two transmission pins 6a1 / 6b1 are symmetrically provided at the opening and closing ends of the two movable buckles 6a / 6b. Specifically, an upwardly extending fixing plate 6a5 / 6b5 can be welded to the outer wall of the opening and closing ends of the two movable buckles 6a / 6b respectively, and then the two transmission pins 6a1 / 6b1 are respectively set on the upper end of the corresponding fixing plate 6a5 / 6b5 in a radially outward manner. The drive mechanism 7 includes a transmission plate 71 that can slide up and down on the inner side of the lower end of the handle 5, a push button 72 that can slide up and down on the outer side of the lower end of the handle 5 and is connected to the transmission plate 71, and a return spring 73 for keeping the push button 72 and the transmission plate 71 in an upward trend. The transmission plate 71 has two symmetrically arranged inclined slots 711 and 712 in an inward V-shape. Two transmission pins 6a1 / 6b1 extend into the two inclined slots 711 and 712 respectively. The upward or downward sliding of the transmission plate 71 can cause the two inclined slots 711 and 712 to move relative to the two transmission pins 6a1 / 6b1. The two transmission pins 6a1 / 6b1 are pushed up or down to move closer together or further apart, thereby causing the opening and closing ends of the two movable latches 6a / 6b to close or open relative to each other. When the opening and closing ends of the two movable latches 6a / 6b are in the relatively closed position, the two transmission pins 6a1 / 6b1 are located at the bottom ends of the two inclined grooves 711 and 712 respectively and are locked. At this time, only by pushing the push button 72 downward to overcome the resistance of the return spring 73 on the push button 72 and the transmission plate 71 can the transmission plate 71 slide downward and cause the two transmission pins 6a1 / 6b1 to unlock and move away from each other.

[0030] In a preferred embodiment of the present invention, the top ends of the two inclined grooves 711 and 712 are respectively provided with limiting grooves 7111 and 7121 communicating with the corresponding inclined grooves. When the opening and closing ends of the two movable buckles 6a / 6b are in the relatively open position, the two transmission pins 6a1 / 6b1 are respectively located in the corresponding limiting grooves 7111 and 7121, so that the opening and closing ends of the two movable buckles 6a / 6b can be maintained in the relatively open position, thereby facilitating the connection and opening of the upper pot body 1 and the lower pot body 2. When the operation is started, if it is necessary to bring the opening and closing ends of the two movable latches 6a / 6b together, simply push the push button 72 upward to move the transmission plate 71 upward. First, let the two transmission pins 6a1 / 6b1 disengage from the limit grooves 7111 and 7121. Then, the transmission plate 71 will slide upward to reset under the tension of the return spring 73, and cause the two transmission pins 6a1 / 6b1 to move closer to each other until the opening and closing ends of the two movable latches 6a / 6b reach the relative closing position.

[0031] In a preferred embodiment of the present invention, the lower end of the handle 5 has a first groove 51 on its inner side for the transmission plate 71 to slide vertically, and a second groove 52 on its outer side for the push button 72 to slide vertically. A return spring 73 is positioned on the side of the second groove 52 closest to the first groove 51, with its upper end abutting against the lower surface of the push button 72 closest to the transmission plate 71, and its lower end abutting against the bottom wall of the second groove 52 closest to the first groove 51. A fastening screw 8 passes through the inner side of the transmission plate 71 and is threadedly connected to the push button 72, thereby fixing the push button 72 and the transmission plate 71 together.

[0032] In a preferred embodiment of the present invention, both movable latches 6a / 6b include arcuate stop walls 6a2 / 6b2 located below the corresponding side of the upper housing connecting seat 3 to prevent the annular engagement portion 41 from disengaging from the receiving portion 301. The radial thickness of the arcuate stop walls 6a2 / 6b2 decreases from the middle to both ends, so that the opening and closing ends of the two movable latches 6a / 6b only need to be opened at a certain angle relative to each other (i.e., only a small opening is needed, without fully opening), which is sufficient to satisfy the requirement of disengaging the annular engagement portion 41 from the receiving portion 301.

[0033] In a preferred embodiment of the present invention, the upper housing connecting seat 3 is a stepped column sleeve structure, which includes an upper column sleeve portion 31 with a smaller diameter, a lower column sleeve portion 32 with a larger diameter, and a first annular step portion 33 formed between the upper column sleeve portion 31 and the lower column sleeve portion 32. A receiving portion 301 is formed inside the lower column sleeve portion 32. The two movable buckles 6a / 6b also include an arcuate sidewall 6a3 / 6b3 wrapped around the corresponding side of the lower column sleeve portion 32 and an arcuate upper wall 6a4 / 6b4 wrapped around the corresponding side of the first annular step portion 33. One end of the arcuate upper wall 6a4 / 6b4 of the two movable buckles 6a / 6b is pivotally connected to one side of the first annular step portion 33 via the same pivot 9.

[0034] In a preferred embodiment of the present invention, the upper pot body 1 includes a pot body 11 and a bottom cover 12. The bottom cover 12 includes a recessed shell 121 located at the center and a first connecting part 122 located on the outer side of the upper end of the recessed shell 121 and welded to the bottom opening of the pot body 11.

The upper shell connecting seat 3 also includes a second annular step part 34 extending radially inward from the upper end of the upper column sleeve part 31. The upper column sleeve part 31 is sleeved on the recessed shell 121. The second annular step part 34 is welded to the bottom surface of the first connecting part 122. A first sealing ring 10 is interference-fitted between the inner circumferential surface of the upper column sleeve part 31 and the outer circumferential surface of the recessed shell 121.

[0035] In a preferred embodiment of the present invention, the lower pot body connecting seat 4 includes an annular peripheral wall 42, a second connecting portion 43 extending radially outward from the lower end of the annular peripheral wall 42, and an annular joint portion 41 formed by first radially outward flange and then axially downward flange from the upper end of the annular peripheral wall 42. A channel is formed inside the annular peripheral wall 42 to communicate with the interior of the lower pot body 2 and the interior of the upper pot body connecting seat 3. The second connecting portion 43 is welded to the upper opening of the lower pot body 2. A second sealing ring 20 is installed at the upper end of the lower pot body connecting seat 4. The second sealing ring 20 includes a lower lip portion 201 that is interference-fitted with the inner circumferential surface of the upper end of the annular peripheral wall 42, an upper lip portion 202 that fits against the inner circumferential surface of the lower end of the upper column sleeve portion 31, and an intermediate main body portion 203 that fits against the upper surface of the annular joint portion 41, the inner circumferential surface of the lower column sleeve portion 32, and the lower surface of the first annular step portion 33.

[0036] Furthermore, the snap-on coffee pot also includes a funnel 30, the lower surface of the upper outer edge of the funnel 30 rests on the inner opening 2031 of the middle main body 203 of the second sealing ring 20, and the first sealing ring 10 has an annular rib 101 that fits against the upper surface of the upper outer edge of the funnel 30.

[0037] Furthermore, the snap-on coffee maker also includes a filter screen 40, which is located between the funnel 30 and the sunken housing 121, and the outer edge of the filter screen 40 is embedded in the opening groove 102 on the inner circumferential surface of the lower end of the first sealing ring 10.

[0038] By setting the first sealing ring 10 and the second sealing ring 20, the gas and liquid of the snap-on coffee pot of the present invention can be effectively prevented from overflowing from the connection gap between the lower pot body connecting seat 4 and the upper pot body connecting seat 3 and the connection gap between the upper pot body connecting seat 3 and the upper pot body 1 during the working process, thus achieving good sealing performance.

[0039] The above description is merely a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention.
