Description

Technical Field

[0001] This utility model relates to the field of coffee machine technology, and specifically to a water-proof structure and coffee machine. Background Technology

[0002] Currently, coffee machines use a method of bending the hot water output pipe to block the hot water output in order to prevent scalding from splashing when the lid is opened. However, this bending method causes excessive deformation of the water pipe, affecting its lifespan and resulting in a relatively high failure rate.

[0003] Utility model patent CN206006950U discloses an anti-splash device for a coffee machine. This device consists of a base with a top cover. One end of the base extends vertically into a plate. A top cover positioning shaft is located at the upper end of the vertical plate, and one end of the top cover is rotatably connected to this shaft. A pressure arm positioning shaft is located at the lower end of the vertical plate, rotatably connected to the lower end of the pressure arm. A fixed pressure point protruding to the right is located on the left side of the lower section of the vertical plate, and a moving pressure point protruding to the left is located on the left side of the lower section of the pressure arm. A horizontal tension spring is connected to the upper left end of the pressure arm. A silicone water pipe passes between the fixed pressure point and the moving pressure point. The concave arc surface of the pressure arm head and the apex corner of one end of the top cover form a linkage pushing surface. This prior art changes the original bent hot water pipe structure to a flattened, clamping structure, thereby extending the lifespan of the hot water pipe. It uses the opening of the top cover to rotate the upper end of the pressure arm, causing the moving pressure point at the lower end of the pressure arm to clamp the rubber pipe, preventing hot water splashing. However, this prior art has a relatively complex structure and high cost.

[0004] Therefore, there is still room for improvement and development in existing technologies. Utility Model Content

[0005] To address the problems of existing technologies, this utility model provides a water-spray-proof structure and a coffee machine. When the lid assembly is opened, the lid assembly causes the pressure-relieving device to separate from the driving component on the housing. The pressure-relieving device flattens the soft water tube, preventing water from flowing through the soft water tube. This achieves the functions of preventing water spray and scalding when the lid is opened, ensuring safe use. Furthermore, the method of flattening the soft water tube can improve its service life. The structure is simple and the cost is low.

[0006] To achieve the above objectives, the technical solution applied in this utility model is as follows:

[0007] A water-spray-proof structure includes a housing with a driving component on the housing; a cover assembly hinged to the housing, the cover assembly having a flexible water pipe and a pressure-relieving device, the pressure-relieving device corresponding to the flexible water pipe and used to release or flatten the flexible water pipe; the driving component corresponding to the pressure-relieving device; when the cover assembly is closed relative to the housing, the pressure-relieving device, through the driving component, drives the flexible water pipe to release; when the cover assembly is open relative to the housing, the pressure-relieving device separates from the driving component, and the pressure-relieving device flattens the flexible water pipe. This configuration ensures that when the cover assembly is closed, the pressure-relieving device on the cover assembly, through the driving component on the housing, releases the flexible water pipe, allowing water to flow through; when the cover assembly is opened, the cover assembly causes the pressure-relieving device to separate from the driving component on the housing, and the pressure-relieving device flattens the flexible water pipe, preventing water flow. This achieves the functions of preventing water spray and scalding when the cover is open, ensuring safe use. Furthermore, the method of flattening the flexible water pipe extends its service life; the structure is simple and inexpensive.

[0008] According to the above scheme, the pressure relief device includes a fixing component, a squeezing component, and a transmission component. The fixing component is fixed to the cover assembly, the squeezing component slides on the cover assembly, and a sliding component is provided between the squeezing component and the cover assembly. An elastic component is provided between the first end of the squeezing component and the cover assembly, and the second end of the squeezing component is correspondingly arranged with the fixing component. The soft water pipe is located between the second end of the squeezing component and the fixing component. The first end of the transmission component is correspondingly arranged with the squeezing component, and the second end of the transmission component is correspondingly arranged with the driving component. With this configuration, the soft water pipe is positioned between the squeezing component and the fixing component. When the cover assembly is closed, the transmission component drives the squeezing component to move away from the fixing component, and the squeezing component moves away from the fixing component. At this time, the soft water pipe is in a released state and water can flow through it, while the elastic component is in a compressed state. When the cover assembly is opened, the cover assembly causes the transmission component and the driving component to separate. Under the rebound force of the elastic component, the squeezing component is pushed to close relative to the fixing component and flatten the soft water pipe, preventing water from flowing through it.

[0009] According to the above scheme, the first end of the extruder is provided with a second transmission part corresponding to the transmission part, and the second end of the extruder is provided with an extrusion part corresponding to the fixing part. The transmission part includes a rocker arm, which is hinged to the cover assembly. The first end of the rocker arm is provided with a pushing part corresponding to the second transmission part of the extruder, and the second end of the rocker arm is provided with a first transmission part corresponding to the driving part. The rocker arm is provided with a first rotating shaft, and the cover assembly is provided with a first connecting hole. The first rotating shaft is rotatably installed in the first connecting hole. The driving part includes a top rod fixed to the housing. The cover assembly is provided with a through hole corresponding to the top rod, and the second end of the transmission part is located above the through hole. With this configuration, when the cover assembly is closed, the first transmission part pushes the second end of the rocker arm upward through the top rod, while the rocker arm rotates around the first rotating shaft, causing the pushing part to move downward and pushing the extruder away from the fixing part.

[0010] According to the above scheme, the elastic element includes a spring, and the cover assembly is provided with a positioning post one fixedly connected to the first end of the spring, and the extrusion component is provided with a positioning post two fixedly connected to the second end of the spring. The positioning post one and the positioning post two are coaxially arranged. This arrangement makes the spring more stable during compression and tension, less prone to deformation, and thus improves its service life.

[0011] According to the above scheme, the sliding assembly includes a slider disposed on the extruder and a groove disposed on the cover assembly, with the slider and the groove being slidably connected.

[0012] According to the above scheme, the cover assembly is provided with a second rotating shaft, and the housing is provided with a second connecting hole. The second rotating shaft is rotatably installed in the second connecting hole.

[0013] The coffee machine described in this utility model includes the aforementioned anti-spray structure.

[0014] The beneficial effects of this utility model are:

[0015] This utility model is designed such that when the cover assembly is opened, the cover assembly causes the pressure relief device to separate from the driving component on the housing. The pressure relief device flattens the soft water pipe, at which point the soft water pipe cannot flow water, thus achieving the functions of preventing water spray and scalding when the cover is opened, making it safe to use. Moreover, the method of flattening the soft water pipe can improve the working life of the soft water pipe. Its structure is simple and the cost is not high. Attached Figure Description

[0022] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1 to 4 As shown, the anti-spray structure of this utility model includes a housing 2, on which a driving component is provided; a cover assembly, which is hinged to the housing 2, and is provided with a soft water pipe 6 and a pressure relief device. The pressure relief device is correspondingly arranged with the soft water pipe 6 and is used to release or flatten the soft water pipe 6; the driving component is correspondingly arranged with the pressure relief device; when the cover assembly is closed relative to the housing 2, the pressure relief device is driven by the driving component to release the soft water pipe 6; when the cover assembly is open relative to the housing 2, the pressure relief device separates from the driving component and flattens the soft water pipe 6. With this configuration, when the cover assembly is closed, the pressure relief device on the cover assembly releases the soft water pipe 6 via the drive component on the housing 2, allowing water to flow through the soft water pipe 6. When the cover assembly is opened, the cover assembly causes the pressure relief device to separate from the drive component on the housing 2, and the pressure relief device flattens the soft water pipe 6, preventing water from flowing through it. This achieves the functions of preventing water spray and scalding when the cover is opened, ensuring safe use. Furthermore, the method of flattening the soft water pipe 6 can improve its service life. Its structure is simple and its cost is low.

[0024] The cover assembly includes an upper cover 1 and a lower cover 11 that are fixedly connected, and a receiving cavity is formed between the upper cover 1 and the lower cover 11. The soft water pipe 6 and the pressure relief device are located in the receiving cavity.

[0025] Furthermore, the pressure relief device includes a fixing member 12, a squeezing member 4, and a transmission member. The fixing member 12 is fixed to the cover assembly, the squeezing member 4 is slidably located on the cover assembly, and a sliding component is provided between the squeezing member 4 and the cover assembly. An elastic component is provided between the first end of the squeezing member 4 and the cover assembly, and the second end of the squeezing member 4 is correspondingly arranged with the fixing member 12. The soft water pipe 6 is located between the second end of the squeezing member 4 and the fixing member 12. The first end of the transmission member is correspondingly arranged with the squeezing member 4, and the second end of the transmission member is correspondingly arranged with the driving member. With this configuration, the soft water pipe 6 is positioned between the squeezing member 4 and the fixing member 12. When the cover assembly is closed, the transmission member drives the squeezing member 4 to move through the driving member, causing the squeezing member 4 to move away from the fixing member 12. At this time, the soft water pipe 6 is in a released state and can flow water, while the elastic component is in a compressed state. When the cover assembly is opened, the cover assembly causes the transmission member and the driving member to separate. Under the rebound force of the elastic component, the squeezing member 4 is pushed to close relative to the fixing member 12 and flatten the soft water pipe 6, preventing water from flowing through the soft water pipe 6.

[0026] Furthermore, the extruder 4 has a transmission part 41 at its first end, corresponding to the transmission component, and an extrusion part 42 at its second end, corresponding to the fixing component 12. The transmission component includes a rocker arm 3, which is hinged to the cover assembly. The rocker arm 3 has a pushing part 31 at its first end, corresponding to the transmission part 41 of the extruder 4, and a transmission part 33 at its second end, corresponding to the driving component. The rocker arm 3 has a rotating shaft 32, and the cover assembly has a connecting hole 13, in which the rotating shaft 32 is rotatably installed. The driving component includes a top rod 21 fixed to the housing 2. The cover assembly has a through hole 17 corresponding to the top rod 21, and the second end of the transmission component is located above the through hole 17. With this configuration, when the cover assembly is closed, the transmission part 33 pushes the rocker arm 3 upward through the top rod 21, while the rocker arm 3 rotates around the rotating shaft 32, causing the pushing part 31 to move downward, pushing the extruder 4 away from the fixing component 12.

[0027] The pivot 32 is located near the pusher 31 on the rocker arm 3. Utilizing the lever principle, the driving force of the elastic element is adjusted based on the distance between the pivot 32 and the center of the pivot, reducing the pressure when closing the cover assembly. Specifically, when the transmission part 33 contacts the pusher 21, the length between the pivot 32 and the transmission part 33 is greater than the length between the pivot 32 and the pusher 31, resulting in less pressure when closing the cover assembly. When the transmission part 33 separates from the pusher 21, the length between the pivot 32 and the transmission part 33 is greater than the length between the pivot 32 and the pusher 31. The length between the pusher 32 and the pusher 31 allows the transmission part 33 to rotate the rocker arm 3 around the axis of the pivot 32 under gravity and reset. The pusher 31 and the transmission part 41 are inclined surfaces. When the pusher 31 moves downward, it slides downward along the inclined surface of the transmission part 41 to push the compression part 42 away from the fixed member 12. When the transmission part 33 rotates the rocker arm 3 around the axis of the pivot 32 under gravity and resets, the pusher 31 moves upward and slides upward along the inclined surface of the transmission part 41.

[0028] Furthermore, the elastic element includes a spring 5, a positioning post 15 fixedly connected to the first end of the spring 5 on the cover assembly, and a positioning post 44 fixedly connected to the second end of the spring 5 on the extrusion member 4. The positioning post 15 and the positioning post 44 are coaxially arranged. This arrangement makes the spring 5 more stable when compressed and stretched, less prone to deformation, and thus improves its service life.

[0029] There are two springs 5. When the rocker arm 3 loses the thrust of the push rod 21, the spring 5 pushes the extrusion part 4 to close relative to the fixed part 12 under the rebound force. During the sliding process, the transmission part 2 41 slides along the inclined surface of the push part 31. Combined with the rocker arm 3 rotating and resetting, the soft water pipe 6 can be quickly flattened, so that the soft water pipe 6 cannot pass water.

[0030] Furthermore, the sliding assembly includes a slider 43 disposed on the extruder 4 and a groove 14 disposed on the cover assembly, wherein the slider 43 and the groove 14 are slidably connected.

[0031] The slider 43 is slidably located within the groove 14 and can be used to limit the sliding stroke of the extruder 4. There are two sliders 43, symmetrically arranged on both sides of the extruder 4. By having the two sliders 43 slide synchronously within the two grooves 14, the extruder 4 becomes more stable during the sliding stroke. The upper and lower outer walls of the slider 43 slide in cooperation with the upper and lower inner walls of the groove 14, respectively, so that the extruder 4 slides horizontally during the sliding stroke and does not move up and down.

[0032] Furthermore, the cover assembly is provided with a second rotating shaft 16, and the housing 2 is provided with a second connecting hole 22, and the second rotating shaft 16 is rotatably installed in the second connecting hole 22.

[0033] The coffee machine described in this utility model includes the aforementioned anti-spray structure.

Those skilled in the art can make many other forms under the guidance of the present utility model without departing from the spirit and scope of the claims, and all of these forms are within the scope of protection of the present utility model.
