Technical Field

[0001] The present application relates to the technical field of coffee machines, and in particular to a residual water spray prevention device for coffee machines. Background Art

[0002] In existing coffee machines, water is heated before entering a filter to soak and extract the coffee powder. Finally, the coffee liquid enters the container below. During this process, some water may remain in the pipes or other components of the coffee machine, causing bacteria or mold to grow in the residual water. This can make the coffee machine difficult to keep clean and may even cause scale accumulation.

[0003] Patent publication number CN211484080U discloses a coffee machine drainage structure comprising a valve body, a wastewater box, an inlet assembly, and a water outlet assembly interconnected with each other. The valve body is provided with a joint connected to a valve cap through the joint. The valve cap is provided with a drain port connected to the wastewater box. A sealing plug is provided between the valve cap and the joint. The sealing plug is movably disposed between the valve cap and the joint and opens or closes the drain port when moved. An axial passage is provided between the valve body and the joint. The axial passage is provided with a through hole connected to the inlet assembly and the water outlet assembly. A valve core and an elastic member are provided in the axial passage. The valve core is mated with the elastic member and elastically movable within the axial passage by the elastic member. The valve core opens or closes the through hole when elastically movable. This drainage structure has the disadvantage that residual water easily accumulates in the drainage pipe, making it difficult to drain the residual water from the coffee machine and failing to achieve effective drainage and anti-spraying properties.

Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0024] like Figure 1 and 2As shown, the present application provides a residual water spray prevention device for a coffee machine, comprising: a water receiving tray 3 and a residual water spray prevention component. The water receiving tray 3 is mounted within a water receiving tray assembly 4 in the coffee machine body. The water receiving tray 3 includes a housing 31 and a support column 32. The support column 32 is disposed within the housing 31, and a water receiving groove 33 is formed between the support column 32 and the inner wall of the housing 31. The residual water spray prevention component is fixedly connected to the support column 32. The residual water spray prevention component defines a residual water spray prevention cavity within the residual water spray prevention cavity. The residual water spray prevention cavity communicates with the water receiving groove 33 and is connected to a drainage pipe 41 of the water receiving tray assembly 4 in the coffee machine body. Water discharged from the drainage pipe 41 flows through the residual water spray prevention cavity into the water receiving groove 33. Specifically, residual water discharged from the coffee machine's drainage and exhaust pipe 5 flows into the drainage pipe 41. Residual water in the drainage pipe 41 flows upward from the bottom into the residual water spray prevention cavity. Residual water in the residual water spray prevention cavity then flows through the drainage hole 23 into the water receiving groove 33, thereby preventing residual water from spraying.

[0025] like Figure 1 and 2 As shown, the residual water spray prevention component includes: a residual water spray prevention lower cover 2 and a residual water spray prevention upper cover 1; the residual water spray prevention lower cover 2 is connected to the top of the support column 32, and the residual water spray prevention upper cover 1 is fixedly connected to the top of the residual water spray prevention lower cover 2; a residual water spray prevention cavity is formed between the residual water spray prevention lower cover 2 and the residual water spray prevention upper cover 1, and the residual water spray prevention lower cover 2 has a drainage hole 23, which is connected to the water receiving trough 33 and the drainage hole 23 is connected to the residual water spray prevention cavity. The drainage hole 23 can be used for both drainage and exhaust. The residual water spray prevention component is arranged inside the water receiving trough 33. The residual water of the coffee machine body enters the drainage pipe 41 of the coffee machine body water receiving tray device 4 through the drainage exhaust pipe 5, and flows from the drainage pipe 41 of the coffee machine body water receiving tray device 4 into the residual water spray prevention cavity. The water in the residual water spray prevention cavity enters the drainage trough 33 through the drainage hole 23. When the water in the water receiving trough 33 reaches a certain height, the water receiving trough 33 is manually removed and the residual water is poured out.

[0026] like Figure 1 and 2 As shown, a first through-hole 34 is formed along the axis of the support column 32. A drainage channel 41 is provided in the center of the coffee machine body, which houses the water receiving tray 4. The drainage channel 41 passes through the first through-hole 34 and communicates with the residual water spray prevention cavity. Residual water in the drainage channel 41 can enter the residual water spray prevention cavity.

[0027] like Figure 1 and 2 As shown, the residual water spray prevention lower cover 2 has a second insertion hole 22. The drainage pipe 41 passes through the first insertion hole 34, then passes through the second insertion hole 22, and is connected to the residual water spray prevention cavity.

[0028] like Figure 1 and 2As shown, a flow rib component 21 is provided in the residual water anti-spout cavity. Preferably, the flow rib component 21 is arc-shaped. The flow rib component 21 realizes the diversion and drainage of water in the residual water anti-spout cavity.

[0029] like Figure 1 and 2 As shown, the bypass ribs 21 include a plurality of bypass ribs 21, which are spaced apart and distributed in the residual water blowout prevention cavity. The plurality of bypass ribs 21 can better achieve the function of diverting and draining the water in the residual water blowout prevention cavity.

[0030] like Figure 1 and 2 As shown, a plurality of drainage holes 23 are distributed on the bottom of the residual water spray prevention lower cover 2. The function of the drainage holes 23 is to allow the water in the residual water spray prevention cavity to enter the water receiving groove 33.

[0031] like Figure 1 and 2 As shown, a sealing ring 6 is provided at the connection between the first through-hole 34 and the second through-hole 22. The function of the sealing ring 6 is to prevent water from leaking out of the connection between the first through-hole 34 and the second through-hole 22. The residual water spray-proof lower cover 2 is provided with a first sealing ring fitting groove 26 at the end located at the second through-hole 22; the support column 32 is provided with a second sealing ring fitting groove 35 at the end located at the first through-hole 34. The first sealing ring fitting groove 26 and the second sealing ring fitting groove 35 are spliced to form a cavity for accommodating the sealing ring 6. The sealing ring 6 is disposed in the cavity formed by the first sealing ring fitting groove 26 and the second sealing ring fitting groove 35.

[0032] like Figure 1 and 2 As shown, the residual water spray prevention lower cover 2 and the residual water spray prevention upper cover 1 are snap-fitted. The residual water spray prevention lower cover 2 has a lower cover snap-fitting portion 24, and the residual water spray prevention upper cover 1 has an upper cover snap-fitting portion 12. The upper cover snap-fitting portion 12 snaps into the lower cover snap-fitting portion 24 to achieve the snap-fitting of the residual water spray prevention lower cover 2 and the residual water spray prevention upper cover 1.

[0033] like Figure 1 and 2 As shown, the bottom of the drain pipe 41 has a drain and exhaust pipe interface 44, which connects to the drain and exhaust pipe 5. The drain and exhaust pipe 5 is installed in a drain and exhaust pipe placement groove 45, which is located at the bottom of the coffee machine body that accommodates the water receiving tray assembly 4. The drain and exhaust pipe 5 drains water into the drain pipe 41, and then from the drain pipe 41 into the water receiving tank 33.

[0034] like Figure 1 and 2As shown, the top of the drainage pipe 41 is provided with a direct spray prevention cover 42 and the side is provided with a drainage vent 43. The direct spray prevention cover 42 blocks the end of the drainage pipe 41 to prevent the residual water from being sprayed directly from the drainage pipe 41. Instead, the residual water flows into the residual water spray prevention cavity from the drainage vent 43 provided on the side of the drainage pipe 41.

[0035] like Figure 1 and 2 As shown, the residual water spray prevention component is fixedly connected to the support column 32 via a fixing member. The residual water spray prevention upper cover 1 has an upper cover mounting hole 11, and the residual water spray prevention lower cover 2 has a lower cover mounting hole 27. The support column 32 is provided with a screw column 36 on the side. The fixing member passes through the upper cover mounting hole 11 and the lower cover mounting hole 27 and is fixedly connected to the screw column 36, thereby achieving a fixed connection between the residual water spray prevention component and the support column 32.

[0036] like Figure 1 and 2 As shown, a positioning column 25 is fixed to the bottom of the residual water spray prevention lower cover 2, and the positioning column 25 is arranged beside the lower cover mounting hole 27; the positioning column 25 is limited to the side of the screw column 36, so that after the residual water spray prevention component is installed on the support column 32, the center lines of the upper cover mounting hole 11, the lower cover mounting hole 27 and the center hole of the screw column 36 coincide, which facilitates the fixing of the residual water spray prevention component and the support column 32.

[0037] Preferably, there are two upper cover mounting holes 11 and two lower cover mounting holes 27, and each lower cover mounting hole 27 is correspondingly arranged below an upper cover mounting hole 11, and there are two screw columns 36, and each screw column 36 is correspondingly arranged below the lower cover mounting hole 27.

[0038] Preferably, there are two positioning posts 25 , each of which is correspondingly arranged beside a lower cover mounting hole 27 , and the positioning posts 25 are used to achieve a guiding and positioning function.

[0039] The beneficial effects achieved by this application are as follows:

[0041] (2) The water receiving tray of the present application is provided with a residual water spray prevention component. The residual water discharged from the drain and exhaust pipe of the coffee machine is discharged into the residual water spray prevention component through the drainage pipe, and then enters the water receiving tray from the drainage hole of the residual water spray prevention component. When the water in the water receiving tray reaches a certain height, the water receiving tray is manually removed and the residual water is poured out. The residual water spray prevention component realizes the diversion and drainage function of discharging the residual water, thereby preventing the residual water from being sprayed everywhere.
