Description

Technical Field

[0001] This utility model relates to the field of coffee machine technology, and in particular to a coffee machine cleaning device. Background Technology

[0002] Current coffee machines often present cleaning challenges during daily use. For example, coffee grounds residue remain on the surface of the brewing head and the inner wall of the extraction funnel, while milk residue accumulates on the surface of the steam wand. These residues are difficult to clean thoroughly and can easily breed bacteria. Users typically use cleaning cloths or scouring pads to scrub, which requires a significant amount of time and often doesn't achieve a complete clean.

[0003] Chinese patent CN220967087U discloses a brewing head that is easy to clean, including a brewing head main unit. A water outlet is provided on one side of the lower end of the brewing head main unit. A switch is provided on one side of the brewing head main unit near the lower end. A cleaning mechanism is provided below the brewing head main unit. The cleaning mechanism includes a cylindrical component. A cylindrical wastewater collection tray is provided on the upper side of the cylindrical component. A cleaning brush component is connected through the wastewater collection tray. A battery component is provided below the cleaning brush component. A handle is provided on one side of the outer ring of the cleaning mechanism near the lower end. A power switch is provided on the upper end of the handle. A drain hole is provided on one side of the outer ring of the cleaning mechanism near the middle end.

[0004] The cleaning mechanism in the prior art requires a water outlet to provide rinsing water during cleaning, and the surface of the water outlet is scrubbed by rotating a brush. The cleaning range and effect are limited, and the function is relatively simple, which cannot meet the cleaning needs of various components of the existing coffee machine's brewing system.

[0005] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a coffee machine cleaning device with a reasonable structure, good cleaning effect, and applicability to cleaning various brewing components.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: The present invention discloses a coffee machine cleaning device, comprising a main unit, which is equipped with a cleaning chamber, a spray assembly, and a controller. The cleaning chamber is provided with a plurality of spray heads and a scrubbing assembly. The spray assembly is connected to the plurality of spray heads through pipes, and the spray heads are provided with a plurality of nozzles. The controller is connected to the spray assembly and the scrubbing assembly through wiring. The cleaning chamber can be paired with a coffee machine device to clean the brewing components through the plurality of spray heads or to clean the steam wand through the scrubbing assembly.

[0008] Understandably, the main parts of a coffee machine that need cleaning are the brewing head, extraction funnel, and steam wand. The brewing head and extraction funnel constitute the brewing assembly. The brewing head comes into direct contact with the coffee grounds in the extraction funnel, and coffee grounds accumulate on its surface and the inner wall of the extraction funnel. The steam wand is used to create milk foam and quickly rinse the coffee container, and its surface is prone to accumulating stubborn milk residue.

[0009] The cleaning chamber on the main unit can connect to the brewing components. The spray assembly provides pressurized water, which is used to rinse the brewing components, namely the brewing head and extraction funnel, through several nozzles on the spray head. The nozzles on the spray head can better rinse the surface of the brewing components, preventing any residue from being missed. Furthermore, the scrubbing assembly located in the cleaning chamber can physically scrub away stubborn milk stains on the steam wand, fully meeting the cleaning needs of various parts of the coffee machine and reducing the user's cleaning time.

[0010] It is understood that the controller is used to control the operation of the spray assembly and the scrubbing assembly to meet the cleaning needs of different brewing components, and has strong compatibility.

[0011] According to the above scheme, the spray assembly includes a water tank and a booster pump. A bottom cover is provided on the lower port of the main unit, and the water tank and booster pump are fixedly installed on the bottom cover. A water outlet is provided at the bottom of the cleaning chamber, and the water outlet is paired and connected to the water tank. The water tank is connected to the booster pump through a main pipe. A splitter is connected to the booster pump, and the splitter is connected to the corresponding spray head through several branch pipes. The booster pump is connected to the controller through a line.

[0012] The booster pump can draw water from the water tank, pressurize it, and then deliver it to each spray head through a distributor. This allows each spray head to spray water evenly in the cleaning chamber to rinse the surface of the cleaning components. The nozzles on the spray heads can be individually controlled to adjust the spray angle, which can better cover the cleaning area and improve the cleaning effect.

[0013] Furthermore, this invention improves rinsing efficiency and effectiveness by using a booster pump and spray heads to provide high-pressure water. The cleaning chamber is connected to a water tank via an outlet. Water rinsed by the spray heads is filtered through a filter screen and then returned to the water tank for reuse, reducing the need for a large water tank volume and resulting in a more compact overall structure. Of course, after cleaning, all used water must be discarded and replaced with fresh, clean water for the next use.

[0014] According to the above scheme, the cleaning chamber includes an opening, which is mounted on the upper port of the main unit. Several sockets are provided on the side wall of the opening, and several spray heads are respectively inserted into the corresponding sockets. The brewing component includes a brewing head and an extraction funnel. The upper opening of the opening can be paired and connected with the brewing head or the extraction funnel.

[0015] The opening can cover the part of the brewing head that needs to be cleaned, and it is also compatible with the size of the extraction funnel for easy assembly and use. Specifically, the outer wall of the opening has several snap-fit ​​structures, allowing the opening to be mounted and fixed to the brewing head like an extraction funnel. When cleaning the extraction funnel, the funnel can be inverted onto the opening, and several spray heads can spray water onto the inner wall of the extraction funnel to clean it.

[0016] Furthermore, the inner cavity of the opening is shaped like a trumpet, wider at the top and narrower at the bottom, to facilitate the return and collection of water sprayed from the spray head. Multiple sockets are provided on the inner wall of the opening for installing the spray head. Specifically, at least four sockets are provided in the opening, and the four sockets are equidistant from the central axis of the opening. Each spray head is provided with at least two nozzles, and the spray range of the nozzles only needs to cover a 90° range. Of course, more spray heads can also be installed in the opening.

[0017] Understandably, several spray heads are tilted and spray towards the brewing component above. Of course, the water sprayed from several spray heads impacts the surface of the brewing component and forms a scattering, which will waste some of the water flow's energy.

[0018] According to the above scheme, preferably, the nozzles on the spray head have different spray angles, that is, the spray heads are tilted upwards towards the opening, but the nozzles on each spray head can have different spray angles, including horizontal and vertical directions, so that the water mist sprayed by each spray head can clean a larger area. Furthermore, the nozzle shape of each spray head can also be different, and multiple spray heads can form a cross spray on the rinsing components, making the cleaning effect more comprehensive and uniform, and preventing residual dead corners.

[0019] According to the above solution, a touch switch is provided at the upper port of the opening, and the touch switch is connected to the controller via a circuit. The touch switch is existing technology; specifically, it includes a triggerable push rod and a micro switch. The micro switch is mounted on the opening from below. A hole is provided at the upper port of the opening, and the push rod can move up and down through the hole, with its lower end touching the micro switch, and its upper end protruding from the upper surface of the opening. When the opening is paired with the brewing head, the touch switch is triggered by pressure, sending a signal to the controller to ensure the cleaning device functions normally, thus preventing accidental triggering.

[0020] According to the above solution, this utility model also includes a filter screen, which is detachably installed inside the opening. The bottom cover has a drain outlet that passes through the water tank, and the drain outlet is equipped with a sealing plug. As described above, the booster pump sprays water from the water tank into the opening through a spray head. The rinsed water is collected and returned to the water tank. To prevent water-insoluble dirt from clogging the pipes, a filter screen is installed inside the opening to filter the returned water. After cleaning, the sealing plug can be removed to drain the wastewater from the water tank, and new water can be added for the next cleaning. Similarly, the filter screen also needs to be cleaned.

[0021] According to the above scheme, the cleaning chamber also includes a submerged hole section, which is installed in the inner cavity of the main unit. The opening is integrally connected to the upper end of the submerged hole section, and the water outlet is located at the bottom of the submerged hole section. A one-way valve is installed in the water outlet section. The washing assembly is located in the submerged hole section, and the steam rod can be inserted into the submerged hole section and paired with the washing assembly.

[0022] A scrubbing assembly is installed inside the countersunk section to clean the output end of the steam rod. During this process, the booster pump is not engaged; the dirt on the surface of the steam rod is cleaned through physical action via the relative movement of the scrubbing assembly and the steam rod. Before cleaning the steam rod, some water needs to be added to the countersunk section. At this time, the one-way valve closes the water outlet, ensuring a shut-off between the cleaning chamber and the water tank. The opening and the countersunk section are an integral structure, and the filter screen is detachably installed between the opening and the countersunk section. The filter screen needs to be removed before cleaning the steam rod.

[0023] According to the above scheme, the washing assembly includes a cleaning brush and a motor. The motor is fixedly connected to the bottom of the countersunk hole and is connected to a controller via a circuit. The bottom of the countersunk hole is also provided with a bearing seat, on which a rotatable transmission bearing is provided. A sealing ring is provided between the transmission bearing and the bearing seat. The transmission bearing is paired with the output shaft of the motor. The cleaning brush is rotatably inserted into the countersunk hole and is detachably connected to the transmission bearing.

[0024] Specifically, when cleaning the steam rod, the booster pump does not need to run. Some water is filled into the countersunk hole, and the cleaning brush is inserted into the countersunk hole. The steam rod can be inserted into the cleaning brush and set concentrically with it. The motor drives the cleaning brush to rotate around the steam rod through the transmission bearing, cleaning the milk residue and other impurities on the surface of the steam rod.

[0025] According to the above scheme, the bottom of the cleaning brush is provided with a meshing terminal and a magnet, and the upper end of the transmission bearing is provided with a meshing port. The cleaning brush can be attracted to the transmission bearing by the magnet, so that the meshing terminal is inserted into the meshing port. Preferably, the cleaning brush can be removed from the countersunk hole for rinsing, and the magnet can attract the bottom of the cleaning brush to the transmission bearing, so that the meshing terminal and the meshing port fit together to form a transmission connection.

[0026] According to the above scheme, the controller is equipped with several control keys and a power interface, and a battery is installed inside the main unit, which is connected to the controller via wiring. A base is provided on the bottom cover, and the controller is fixed to the base. It is understood that the controller needs to control the start and stop of the booster pump and motor, and detect the usage status of the main unit based on the touch switch. Typically, the control keys need to have a power option and at least two other function options. Furthermore, this invention can use an external power supply, i.e., connected to a power cord via a power interface, or a battery can be installed inside the main unit to power it.

[0027] This utility model discloses a coffee machine cleaning device. The main unit is equipped with a cleaning chamber that can be installed on a coffee machine. The spray assembly rinses the brewing components through the spray head. The spray head has multiple nozzles with a large cleaning range and good cleaning effect. It can also clean the steam rod through the brush assembly. It has strong compatibility and is easy to use. Attached Figure Description

[0030] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0031] like Figure 1-6 As shown, the coffee machine cleaning device of this utility model includes a main unit 1. The main unit 1 is provided with a cleaning chamber 2, a spray assembly 100 and a controller 11. The cleaning chamber 2 is provided with a plurality of spray heads 21 and a scrubbing assembly 200. The spray assembly 100 is connected to the plurality of spray heads 21 through pipes. The spray heads 21 are provided with a plurality of nozzles. The controller 11 is connected to the spray assembly 100 and the scrubbing assembly 200 through wiring. The cleaning chamber 2 can be paired with a coffee machine device to clean the brewing components through the plurality of spray heads 21 or to clean the steam wand 103 through the scrubbing assembly 200.

[0032] Understandably, the main components of a coffee machine that require cleaning are the brewing head 101, the extraction funnel 102, and the steam wand 103. The brewing head 101 and the extraction funnel 102 constitute the brewing assembly. The brewing head 101 is in direct contact with the coffee grounds in the extraction funnel 102, and coffee grounds will accumulate on its surface and the inner wall of the extraction funnel 102. The steam wand 103 is used to create milk foam and quickly rinse the coffee container, and its surface is prone to accumulating stubborn milk residue.

[0033] The cleaning chamber 2 on the main unit 1 can connect to the brewing components. The spray assembly 100 can provide pressurized water, which is used to rinse the brewing components, namely the brewing head 101 and the extraction funnel 102, through several nozzles on the spray head 21. The nozzles on the spray head 21 can better rinse the surface of the brewing components and avoid any residue. Furthermore, the scrubbing assembly 200 located in the cleaning chamber 2 can physically scrub away stubborn milk stains on the steam wand 103, fully meeting the cleaning needs of various parts of the coffee machine and reducing the user's cleaning operation time.

[0034] It is understood that the controller 11 is used to control the operation of the spray assembly 100 and the scrubbing assembly 200 to meet the cleaning needs of different brewing components, and has strong compatibility.

[0035] The spray assembly 100 includes a water tank 3 and a booster pump 31. A bottom cover 12 is provided on the lower port of the main unit 1, and the water tank 3 and the booster pump 31 are fixedly mounted on the bottom cover 12. The bottom of the cleaning chamber 2 is provided with a water outlet 22, which is paired with the water tank 3. The water tank 3 is connected to the booster pump 31 through a main pipe. A splitter 32 is connected to the booster pump 31. The splitter 32 is connected to the corresponding spray head 21 through several branch pipes. The booster pump 31 is connected to the controller 11 through a line.

[0036] The booster pump 31 can draw water from the water tank 3, pressurize it, and then deliver it to each spray head 21 through the distributor 32, so that each spray head 21 can spray water evenly in the cleaning chamber 2 to rinse the surface of the cleaning components. The nozzles on the spray heads 21 can be controlled to control the spray angle, which can better cover the cleaning range and improve the cleaning effect.

[0037] Furthermore, this invention improves rinsing efficiency and effectiveness by providing high-pressure water through the booster pump 31 and the spray head 21. The cleaning chamber 2 is connected to the water tank 3 via the water outlet 22. The water rinsed by the spray head 21 is filtered by the filter screen 33 and then flows back into the water tank 3 from the water outlet 22 for reuse, thus reducing the need for a large volume in the water tank 3 and making the overall structure more compact. Of course, after cleaning, all the used water needs to be discarded and replaced with fresh, clean water for the next use.

[0038] like Figure 3-5 As shown, the cleaning chamber 2 includes an opening 201, which is mounted on the upper port of the main unit 1. Several sockets 23 are provided on the side wall of the opening 201, and several spray heads 21 are respectively inserted into the corresponding sockets 23. The brewing component includes a brewing head 101 and an extraction funnel 102. The upper opening of the opening 201 can be paired and connected with the brewing head 101 or the extraction funnel 102.

[0039] The opening 201 can cover the part of the brewing head 101 that needs to be cleaned, and it is also compatible with the size of the extraction funnel 102 for easy assembly and use. Specifically, the outer wall of the opening 201 is provided with several snap-fit ​​structures, allowing the opening 201 to be fixed onto the brewing head 101 like the extraction funnel 102. When cleaning the extraction funnel 102, the extraction funnel 102 can be inverted onto the opening 201, and several spray heads 21 can spray water onto the inner wall of the extraction funnel 102 to clean it.

[0040] Furthermore, the inner cavity of the opening 201 is flared, wider at the top and narrower at the bottom, to facilitate the return and collection of water sprayed from the spray head 21. Multiple sockets 23 are provided on the inner wall of the opening 201 for installing the spray head 21. Specifically, the opening 201 has at least four sockets 23, which are equidistant from each other around the central axis of the opening 201. Each spray head 21 has at least two nozzles, and the spray range of the nozzles only needs to cover a 90° range. Of course, more spray heads 21 can also be installed in the opening 201.

[0041] Understandably, several spray heads 21 are tilted and spray towards the upward rinsing component. Of course, the water sprayed from several spray heads 21 impacts the surface of the rinsing component and forms a scattering, which will waste some of the energy of the water flow.

[0042] Preferably, the nozzles on the spray head 21 have different spray angles, meaning that the spray heads 21 are tilted upwards towards the opening 201, but each nozzle on the spray head 21 can have different spray angles, including both horizontal and vertical directions, so that the water mist sprayed by each spray head 21 can clean a wider area. Furthermore, the nozzle shape on each spray head 21 can also be different, and multiple spray heads 21 can form a cross-spray on the rinsing components, making the cleaning effect more comprehensive and uniform, and preventing residual dead corners.

[0043] A touch switch 24 is provided at the upper port of the opening 201, and the touch switch 24 is connected to the controller 11 via a circuit. The touch switch 24 is existing technology; specifically, it includes a triggerable push rod and a micro switch. The micro switch is mounted on the opening 201 from below. A hole is provided at the upper port of the opening 201, through which the push rod can move vertically, with its lower end touching the micro switch, and its upper end protruding from the upper surface of the opening 201. When the opening 201 is paired with the brewing head 101, the touch switch 24 is triggered by pressure, sending a signal to the controller 11 to ensure the cleaning device functions normally, thus preventing accidental triggering.

[0044] This utility model also includes a filter screen 33, which is detachably installed inside the opening 201. The bottom cover 12 has a drain port 13 that passes through the water tank 3, and the drain port 13 is equipped with a sealing plug 14. As described above, the booster pump 31 sprays water from the water tank 3 into the opening 201 through the spray head 21. The rinsed water is collected and returned to the water tank 3. To prevent water-insoluble dirt from clogging the pipes, the filter screen 33 installed inside the opening 201 filters the returned water. After cleaning, the sealing plug 14 can be removed to drain the wastewater from the water tank 3, and new water can be added for the next cleaning. Similarly, the filter screen 33 also needs to be cleaned.

[0045] like Figure 6 As shown, the cleaning chamber 2 also includes a recessed section 202, which is inserted into the inner cavity of the main unit 1. The opening 201 is integrally connected to the upper end of the recessed section 202. The water outlet 22 is located at the bottom of the recessed section 202, and a one-way valve 221 is provided inside the water outlet 22. The washing assembly 200 is located inside the recessed section 202, and the steam rod 103 can be inserted into the recessed section 202 and paired with the washing assembly 200.

[0046] A scrubbing assembly 200 is installed inside the recessed section 202 to clean the output end of the steam rod 103. During this time, the booster pump 31 is not involved in operation; the dirt on the surface of the steam rod 103 is cleaned through physical action via the relative movement between the scrubbing assembly 200 and the steam rod 103. Before cleaning the steam rod 103, some water needs to be added to the recessed section 202. At this time, the one-way valve 221 closes the water outlet 22, keeping the cleaning chamber 2 and the water tank 3 in a shut-off state. The opening 201 and the recessed section 202 are an integral structure. The filter screen 33 is detachably installed between the opening 201 and the recessed section 202. Before cleaning the steam rod 103, the filter screen 33 needs to be removed for use.

[0047] The washing assembly 200 includes a cleaning brush 4 and a motor 41. The motor 41 is fixedly connected to the bottom of the countersunk hole 202 and is connected to the controller 11 via a circuit. The bottom of the countersunk hole 202 is also provided with a bearing seat 25, on which a rotatable transmission bearing 26 is provided. A sealing ring is provided between the transmission bearing 26 and the bearing seat 25. The transmission bearing 26 is paired with the output shaft of the motor 41. The cleaning brush 4 is rotatably inserted into the countersunk hole 202, and the cleaning brush 4 is detachably connected to the transmission bearing 26.

[0048] Specifically, when cleaning the steam rod 103, the booster pump 31 does not need to run. Some water is put into the countersunk hole 202, and the cleaning brush 4 is inserted into the countersunk hole 202. The steam rod 103 can be inserted into the cleaning brush 4 and set concentrically with it. The motor 41 drives the cleaning brush 4 to rotate around the steam rod 103 through the transmission bearing 26, so as to clean the milk residue and other substances on the surface of the steam rod 103.

[0049] The cleaning brush 4 has a meshing terminal 42 and a magnet 43 at its bottom, and a meshing port 44 at its upper end. The cleaning brush 4 can be attracted to the transmission bearing 26 by the magnet 43, so that the meshing terminal 42 is inserted into the meshing port 44. Preferably, the cleaning brush 4 can be detached from the countersunk hole 202 for rinsing, and the magnet 43 can attract the bottom of the cleaning brush 4 to the transmission bearing 26, so that the meshing terminal 42 and the meshing port 44 fit together to form a transmission connection.

[0050] The controller 11 is equipped with several control keys 16 and a power interface 17. A battery 18 is installed inside the main unit 1, and the battery 18 is connected to the controller 11 via wiring. A base 15 is provided on the bottom cover 12, and the controller 11 is fixed to the base 15. It is understood that the controller 11 needs to control the start and stop of the booster pump 31 and the motor 41, and detect the usage status of the main unit 1 according to the touch switch 24. Typically, the control keys 16 need to have a power option and at least two other function options. Furthermore, this invention can use an external power supply, i.e., connected to a power cord via the power interface 17, or the battery 18 can be installed inside the main unit 1 to power the main unit 1.

[0051] The above description is only a preferred embodiment of the present utility model.
