[0040] Reference Figures 1 to 7According to the first aspect of the utility model, a fixing mechanism for a coffee machine includes a body 100, a suction cup body 200 and an adjusting assembly 300. The suction cup body 200 is arranged on the body 100 and has an adsorption surface 210. The adsorption surface 210 is used to adsorb the supporting member. The adsorption surface 210 can be deformed so that the suction cup body 200 has a suction state and a release state. The adjusting assembly 300 can be movably arranged on the body 100, and the adjusting assembly 300 is connected to a side of the suction cup body 200 away from the adsorption surface 210. The adjusting assembly 300 is used to drive the suction cup body 200 to switch between the suction state and the release state. In this way, when the suction cup body 200 is in the suction state, the body 100 can be stably fixed on the supporting member, and the user does not need to fix the body 100 with one hand, which can be convenient for the user to use.

[0041] Specifically, when the user uses the coffee machine, the user can move the adjustment component 300 to put the suction cup body 200 in a sucked state. At this time, the distance between the adsorption surface 210 and the supporting member increases, and the air pressure in the sealed space formed by the adsorption surface 210 and the supporting member is lower than the atmospheric pressure. Under the action of atmospheric pressure, the suction cup body 200 is tightly attached to the supporting member. When the user installs or removes the funnel, the body 100 can be stably fixed on the supporting member. The user does not need to fix the body 100 with one hand, which is convenient for the user to use.

[0042] It is understandable that when the user needs to move the position of the coffee machine, the user can move the adjustment component 300 in the reverse direction so that the suction cup body 200 is in a loosened state. At this time, the distance between the adsorption surface 210 and the supporting member is reduced, and the air pressure in the sealed space formed by the adsorption surface 210 and the supporting member is equal to the atmospheric pressure. The suction cup body 200 is not tightly attached to the supporting member, and the operation is simple, convenient and fast, which can be convenient for users to use.

[0043] It should be noted that the supporting member may be a table, a counter or other components, and is not limited here.

[0044] Reference Figure 8 In some embodiments of the utility model, the adjustment component 300 includes an adjustment member 310 and a connecting member 320, one end of the connecting member 320 is connected to the side of the suction cup body 200 away from the adsorption surface 210, the body 100 is provided with a through hole 110, and the connecting member 320 is movably arranged in the through hole 110, and a transmission structure is provided between the other end of the connecting member 320 and the adjustment member 310. Through the transmission structure, the adjustment member 310 drives the suction cup body 200 to switch between the suction state and the release state, which can facilitate the body 100 to be fixed on the supporting member for user convenience.

[0045] Specifically, the through hole 110 is extended in the up and down directions, the suction cup body 200 is arranged at the bottom of the body 100, the suction cup surface is arranged downward, and the connecting member 320 is passed through the through hole 110. When the adjusting member 310 drives the connecting member 320 to move through the transmission structure, it can drive the adsorption surface 210 to deform, so that the distance between the adsorption surface 210 and the supporting member increases or decreases, so that the suction cup body 200 switches between the suction state and the release state, which can facilitate the body 100 to be fixed on the supporting member for the convenience of user use.

[0046] It should be noted that the connecting member 320 is connected to the suction cup body 200 through the fastener 400, and the fastener 400 is a component such as a bolt or a screw. A sealing gasket 500 is provided between the fastener 400 and the suction cup body 200 to improve the sealing performance of the suction cup body 200, which is not limited here.

[0047] Reference Figure 4 , Figure 7 and Figure 8 In some embodiments of the utility model, the transmission structure includes a cam portion 311 provided on the adjusting member 310, the cam portion 311 is hinged to one end of the connecting member 320 away from the suction cup body 200, the cam portion 311 is in contact with the body 100, and the user can drive the connecting member 320 to move by rotating the adjusting member 310. The operation is simple, convenient and fast, and the suction cup body 200 can be switched between a tightened state and a loosened state.

[0048] Specifically, the cam portion 311 is hinged to the connecting piece 320 via the hinge shaft 330. When the suction cup body 200 is switched from a loose state to a tightened state, the distance between the hinge shaft 330 and the bottom of the body 100 increases, causing the connecting piece 320 to move upward, and the distance between the adsorption surface 210 and the supporting piece increases. The air pressure in the sealed space formed by the adsorption surface 210 and the supporting piece is lower than the atmospheric pressure, and the sealed space is in a negative pressure state, which can prevent the body 100 from moving when installing or disassembling the funnel, so that the user does not need to press the body 100 with one hand, which is convenient for the user to use.

[0049] It can be understood that when the suction cup body 200 switches from a sucked state to a released state, the distance between the hinge shaft 330 and the bottom of the body 100 is reduced, causing the connecting member 320 to move downward, and the distance between the adsorption surface 210 and the supporting member is reduced. The air pressure in the sealed space formed by the adsorption surface 210 and the supporting member is equal to the atmospheric pressure, so that the suction cup body 200 releases the body 100, and the user can move the position of the body 100 without being restricted here.

[0050] It should be noted that the transmission structure can also be a threaded transmission structure, which includes an external thread provided on the connecting member 320 and an internal thread provided on the adjusting member 310. The adjusting member 310 can be rotatably mounted on the connecting member 320 and can abut against the periphery of the through hole 110. The internal thread cooperates with the external thread and can also drive the connecting member 320 to move in the up and down directions so as to deform the adsorption surface 210. There is no limitation here.

[0051] It should be noted that the transmission structure can also be a slope pushing structure, which includes a first slope provided on the connecting member 320 and a second slope provided on the adjusting member 310. The adjusting member 310 is slidably provided on the body 100, and the first slope is in contact with the second slope, and the second slope is located below the first slope. When the adjusting member 310 slides, the second slope can push the first slope to move upward, so that the connecting member 320 moves upward, and the air pressure in the sealed space formed by the adsorption surface 210 and the supporting member is lower than the atmospheric pressure, and the sealed space is in a negative pressure state, which is not limited here.

[0052] Reference Figure 8 , Fig. 9 In some embodiments of the utility model, the cam portion 311 is provided with a limit strip 314, which can abut against the machine body 100. The limit strip 314 is used to limit the suction cup body 200 from switching from a tightened state to a loosened state, so as to avoid the cam portion 311 from automatically rotating under unexpected circumstances, causing the suction cup body 200 to switch from a tightened state to a loosened state, thereby improving the reliability of the coffee machine.

[0053] Refer to Figure 4. Figure 7 and Figure 8 In some embodiments of the utility model, the connecting member 320 includes a first connecting portion 321 and a second connecting portion 322 connected to the first connecting portion 321, the first connecting portion 321 is connected to the suction cup body 200, the second connecting portion 322 is passed through the through hole 110 and is hinged to the cam portion 311, and along the axial direction perpendicular to the through hole 110, the cross-section of the second connecting portion 322 is a non-circular structure, and the cross-section of the second connecting portion 322 matches the cross-section of the through hole 110, which can limit the rotation of the connecting member 320 for user convenience.

[0054] Specifically, along the axial direction perpendicular to the through hole 110, the cross-section of the second connecting portion 322 and the cross-section of the through hole 110 are both rectangular structures, and the cross-section of the second connecting portion 322 matches the cross-section of the through hole 110, so that the second connecting portion 322 can abut against the side wall of the through hole 110, and can limit the rotation of the connecting member 320 to facilitate user use.

[0055] Reference Figure 8In some embodiments of the utility model, a first pulling portion 312 and a second pulling portion 313 are provided at one end of the adjusting member 310 away from the connecting member 320. The first pulling portion 312 and the second pulling portion 313 are arranged relative to each other, which can facilitate the user to pull the adjusting member 310 to rotate, so as to switch the suction cup body 200 between the sucked state and the released state.

[0056] Specifically, when the suction cup body 200 is in a released state, the user can pull the adjusting member 310 to rotate through the first pulling part 312 to switch the suction cup body 200 to a suctioned state. When the suction cup body 200 is in a suctioned state, the user can pull the adjusting member 310 to rotate through the second pulling part 313 to switch the suction cup body 200 to a released state. This allows the user to pull the adjusting member 310 to rotate, so that the suction cup body 200 can switch between a suctioned state and a released state.

[0057] It should be noted that by arranging the first pulling portion 312 and the second pulling portion 313 at one end of the adjusting member 310 away from the connecting member 320, the distance between the first pulling portion 312 and the second pulling portion 313 and the hinge shaft 330 is the longest, which can increase the force of the first pulling portion 312 and the second pulling portion 313 to reduce the force of the user turning the adjusting member 310, which is not elaborated here.

[0058] Reference Figure 4 , Figure 7 and Fig.10 In some embodiments of the present invention, a positioning structure is provided between the suction cup body 200 and the body 100, which can circumferentially position the suction cup body 200 to prevent the suction cup body 200 from moving left and right relative to the body 100, and can better fix the body 100 on the supporting member.

[0059] Reference Figure 4 , Figure 7 and Fig.10 In some embodiments of the utility model, the positioning structure includes a positioning groove 220 provided on the suction cup body 200 and a positioning protrusion 120 provided on the body 100. The positioning protrusion 120 is accommodated in the positioning groove 220, and can circumferentially position the suction cup body 200 to prevent the suction cup body 200 from moving left and right relative to the body 100, so as to better fix the body 100 on the supporting member.

[0060] Specifically, the positioning groove 220 is extended along the circumference of the suction cup body 200, and the notch of the positioning groove 220 faces the connecting piece 320. The positioning protrusion 120 is arranged at the bottom of the body 100, and the positioning protrusion 120 is an annular structure. The positioning protrusion 120 is accommodated in the positioning groove 220, and can perform circumferential positioning of the suction cup body 200 to prevent the suction cup body 200 from moving left and right relative to the body 100, and can better fix the body 100 on the supporting member.

[0061] It should be noted that the positions of the positioning groove 220 and the positioning protrusion 120 can also be interchanged, that is, the positioning groove 220 is arranged on the body 100, and the positioning protrusion 120 is arranged on the suction cup body 200, which is not limited here.

[0062] It is understandable that the positioning structure may also be a structure in which the positioning pin and the positioning hole cooperate well, which will not be described in detail here.

[0063] Reference Figure 4 , Figure 7 and Fig.11 In some embodiments of the utility model, a sealing protrusion 230 is provided on the side of the suction cup body 200 away from the connecting piece 320. The sealing protrusion 230 is extended along the circumference of the suction cup body 200. The sealing protrusion 230 is used to be in close contact with the supporting piece, and can seal the sealed space formed by the adsorption surface 210 and the supporting piece to avoid the suction cup body 200 from leaking and causing the suction cup body 200 to fail to suck the supporting piece tightly.

[0064] Specifically, there are two sealing protrusions 230, and the sealing protrusions 230 are annular structures. The two sealing protrusions 230 are concentrically arranged. The sealing protrusions 230 can be tightly attached to the supporting member to seal the sealed space formed by the adsorption surface 210 and the supporting member, thereby avoiding the suction cup body 200 from leaking and causing the suction cup body 200 to be unable to suck the supporting member tightly.

[0065] Reference Figure 1 , Figure 2 The coffee machine according to the second embodiment of the utility model includes the fixing mechanism for the coffee machine according to the first embodiment of the utility model. When the suction cup body 200 is in a sucked state, the machine body 100 can be stably fixed on the supporting member, and the user does not need to fix the machine body 100 with one hand, which is convenient for the user to use.

[0066] Specifically, when the user uses the coffee machine, the user can move the adjustment component 300 to put the suction cup body 200 in a sucked state. At this time, the distance between the adsorption surface 210 and the supporting member increases, and the air pressure in the sealed space formed by the adsorption surface 210 and the supporting member is lower than the atmospheric pressure. Under the action of atmospheric pressure, the suction cup body 200 is tightly attached to the supporting member. When the user installs or removes the funnel, the body 100 can be stably fixed on the supporting member. The user does not need to fix the body 100 with one hand, which is convenient for the user to use.

[0067] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The embodiment is described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiment, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the present purpose.
