Description

Technical Field

[0001] The present invention relates to the technical field of coffee machines, and in particular to a coffee machine powder bowl with a temperature monitoring function. Background Art

[0002] With the popularity of coffee culture, coffee machines are being adopted by more and more families. For example, the invention application with the publication number CN116649779A discloses a similar coffee machine. The working principle of the coffee machine is mainly to buckle the powder bowl filled with coffee powder to the brewing head of the coffee machine, and then extract the flavor substances in the coffee powder by controlling the water temperature and pressure of the brewing head. Therefore, water temperature and extraction pressure have become important factors in evaluating the quality of coffee machines.

[0003] However, conventional coffee machines usually place temperature sensors in water tanks or water pipes. When the water in the water tank is heated to a certain temperature by the internal heater and flows out through the water pipe, the outlet water temperature will be lower than the original temperature, which will result in the extraction temperature of the coffee powder not reaching the ideal value, and ultimately affect the coffee flavor. If the temperature sensor is placed directly on the powder bowl, it will be difficult to clean the powder bowl due to the waterproof considerations of the relevant detection circuit, so there is room for improvement. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a coffee machine powder bowl with a temperature monitoring function, which can not only accurately monitor the water temperature in the powder bowl, but also ensure the safety of the detection circuit when the powder bowl is washed.

[0005] In order to solve the above technical problems, the present invention is solved by the following technical solutions: A coffee machine powder bowl with a temperature monitoring function comprises a powder bowl body, a pile head is provided on the outer side wall of the powder bowl body, a handle is detachably connected to the pile head, a temperature sensor is built-in on the side wall of the powder bowl body at a position corresponding to the pile head, a signal output line of the temperature sensor passes through the pile head and is electrically connected to a waterproof signal connector, the waterproof signal connector is provided at one end of the pile head away from the powder bowl body and is sealed and connected to the connection of the pile head; a connecting rod extends from one end of the handle close to the pile head, a signal interface for plugging the waterproof signal connector is provided at one end of the connecting rod away from the handle, and an output end of the signal interface is electrically connected to a detection module provided in the handle; buckling grooves are provided on the upper and lower sides of the pile head and at a position close to the handle, buckling plates buckled in the two buckling grooves are provided on the upper and lower sides of the connecting rod, respectively, and an elastic driving mechanism installed on the connecting rod so that the buckling plate can maintain a buckling state with the buckling groove and a driving member that responds to an external trigger to overcome the elastic driving force of the elastic driving mechanism to drive the buckling plate out of the buckling groove; When the connecting rod is connected to the pile head so that the waterproof signal connector is connected to the signal interface, the elastic driving mechanism can drive the buckle plate to buckle into the corresponding buckle groove, thereby preventing the connecting rod from being separated from the pile head; When the connecting rod is separated from the pile head to separate the waterproof signal connector from the signal interface, the elastic driving mechanism can drive the two buckle plates to bite each other on the side of the connecting rod away from the handle, thereby sealing the signal interface.

[0006] By adopting the above scheme, the detachable design of the handle and the powder bowl body can realize the separation and docking of the temperature sensor and the rear detection module. When the two are docked, the temperature sensor and the detection module are connected, so that the detection module can obtain the temperature value measured by the temperature sensor. At this time, the connecting rod on the handle and the pile head on the powder bowl body can be locked together by the buckle connection between the buckle plate and the buckle groove, thereby completing the fixed connection between the handle and the powder bowl body. When the driving member drives the buckle plate to disengage from the buckle groove in response to an external trigger, the lock between the connecting rod and the pile head can be released. When the connecting rod is separated from the pile head, the signal interface can be separated from the waterproof signal connector to cut off the connection between the temperature sensor and the rear detection module. At this time, if the driving member is released, the two buckle plates can be driven by the elastic driving mechanism to bite each other to cover the side of the connecting rod away from the handle, thereby protecting the signal interface. In this state, the user can directly wash the powder bowl body alone without having to worry about the waterproof problem of the rear detection module. Since the temperature sensor and waterproof signal connector on the powder bowl body have been fully waterproofed, they will not be affected by water washing, thereby effectively improving the efficiency and convenience of powder bowl cleaning.

[0007] Preferably, the elastic driving mechanism includes a connecting plate vertically arranged at the rear end of the buckle plate, and a spring hinge arranged between the end of the connecting plate away from the buckle plate and the connecting rod so that the connecting plate has a tendency to rotate and fit the surface of the connecting rod.

[0008] The above solution makes the structure of the elastic drive mechanism simpler and the operation more efficient and stable.

[0009] Preferably, the driving member is a pressure plate which is arranged at one end of the connecting plate away from the buckle plate and is inclined in a direction away from the connecting rod.

[0010] The above solution makes the structure of the driving member simpler and the operation easier and faster.

[0011] Preferably, a locking groove is provided on the plate surface of the buckle plate close to the connecting rod, and when the buckle plate is buckled in the buckle groove, the locking groove can be buckled to the edge of the buckle groove opening close to the connecting rod.

[0012] With the above solution, when the snap-on plate is snapped into the corresponding snap-on groove, the snap-on cooperation between the locking groove and the opening edge of the snap-on groove can prevent the snap-on plate from passively detaching from the snap-on groove, thereby further improving the connection stability between the connecting rod and the pile head.

[0013] Preferably, positioning columns are provided on both the left and right sides of the pile head, and the positioning columns are arranged along the length direction of the pile head. Positioning seats are provided on both the left and right sides of the connecting rod, and positioning holes are provided on the positioning seats for the positioning columns to be inserted.

[0014] By adopting the above scheme, the cooperation between the positioning column and the positioning hole can not only realize the pre-positioning when the connecting rod and the pile head are connected, thereby improving the connection efficiency and convenience, but also play a lateral limiting role, further improving the connection stability between the connecting rod and the pile head.

[0015] Preferably, the detection module includes a control board electrically connected to the output end of the signal interface and a wireless transmitting unit integrated on the control board, the wireless transmitting unit is wirelessly connected to a wireless receiving unit, and the wireless receiving unit is integrated in the control module of the coffee machine; when the waterproof signal connector is docked with the signal interface, the temperature sensor can send the measured temperature value to the control board, and the control board transmits the received temperature value to the control module through wireless transmission between the wireless transmitting unit and the wireless receiving unit, so that the control module can monitor the temperature inside the powder bowl body.

[0016] By adopting the above solution, the temperature value measured by the temperature sensor can be transmitted to the control module built into the coffee machine, so that the control module can monitor the temperature change in the powder bowl in real time and ensure the monitoring accuracy. At the same time, the wireless transmission method can save the trouble of the wire harness, making the operation of the powder bowl more convenient and making the appearance of the coffee machine neater.

[0017] Preferably, a power supply unit for supplying power to the control board is integrated on the control board, and a charging interface is electrically connected to the power supply unit.

[0018] With the above solution, the power supply unit can provide power to the control board and components on the control board (such as temperature sensors, wireless transmitters, etc.), thereby ensuring that the control board can operate stably. The charging interface can charge the power supply unit to maintain the endurance of the control board.

[0019] Preferably, the handle is provided with a mounting groove for placing the control panel, and the opening of the mounting groove is covered with a sealing cover.

[0020] By adopting the above scheme, the installation slot can provide a placement space for the control board, and the cover covering the opening of the installation slot can not only protect the control board in the installation slot, but also facilitate the opening of the installation slot, thereby facilitating the maintenance of the control board and the charging of the power supply unit, which is more user-friendly.

[0021] Preferably, a pressure sensor is provided on the inner wall of the powder bowl body at a position corresponding to the pile head. The pressure sensor is sealed at the junction with the powder bowl body. The signal output line of the pressure sensor passes through the pile head and is electrically connected to the waterproof signal connector.

[0022] By adopting the above solution, the pressure sensor can directly detect the extraction pressure in the powder bowl body, thereby improving the pressure detection accuracy and making the taste of the coffee extraction liquid better.

[0023] Preferably, the wireless transmitting unit is wirelessly connected to at least one wireless display terminal to receive and display the temperature value measured by the temperature sensor.

[0024] By adopting the above solution, the user can monitor the temperature changes in the powder bowl body through the mobile display terminal, which can not only improve the convenience of use, but also facilitate the teaching of the coffee machine and be more humane.

[0025] The present invention has significant technical effects due to the adoption of the above technical solutions: the detachable design of the handle and the powder bowl body can realize the separation and docking of the temperature sensor and the rear detection module. When the two are docked, the temperature sensor and the detection module are connected, so that the detection module can obtain the temperature value measured by the temperature sensor. At this time, the connecting rod on the handle and the pile head on the powder bowl body can be locked together by the buckle connection between the buckle plate and the buckle groove, thereby completing the fixed connection between the handle and the powder bowl body. When the driving member drives the buckle plate to disengage from the buckle groove in response to an external trigger, the lock between the connecting rod and the pile head can be released. When the connecting rod is separated from the pile head, the signal interface can be separated from the waterproof signal connector to cut off the connection between the temperature sensor and the rear detection module. At this time, if the driving member is released, the two buckle plates can be driven by the elastic driving mechanism to bite each other to cover the side of the connecting rod away from the handle, thereby protecting the signal interface. In this state, the user can directly wash the powder bowl body alone without having to consider the waterproof problem of the rear detection module. Since the temperature sensor and waterproof signal connector on the powder bowl body have been fully waterproofed, they will not be affected by water washing, thereby effectively improving the efficiency and convenience of powder bowl cleaning.

[0028] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. Example

[0029] like Figures 1 to 11As shown, the present embodiment discloses a coffee machine powder bowl with a temperature monitoring function, including a powder bowl body 1, the outer side wall of the powder bowl body 1 is integrally provided with a pile head 2, and the pile head 2 is detachably connected with a handle 3. A temperature sensor 4 is built into the side wall of the powder bowl body 1 at a position corresponding to the pile head 2, so as to monitor the temperature inside the powder bowl body 1 through the heat conduction of the powder bowl body 1 itself, so as to accurately obtain the water temperature inside the powder bowl body 1. The signal output line 5 of the temperature sensor 4 passes through the pile head 2 from the inside and is electrically connected to a waterproof signal connector 6, which is arranged at one end of the pile head 2 away from the powder bowl body 1 and is sealed and connected to the connection with the pile head 2. Specifically, a mounting hole 30 for the waterproof signal connector 6 to be placed is provided at the end of the pile head 2 away from the powder bowl body 1, and a sealant is filled between the waterproof signal connector 6 and the mounting hole 30, so as to play an all-round waterproof role. Correspondingly, a connecting rod 7 extends from one end of the handle 3 close to the pile head 2, and a signal interface 8 for plugging in the waterproof signal connector 6 is provided at one end of the connecting rod 7 away from the handle 3, and the output end of the signal interface 8 is electrically connected to a detection module 9 provided in the handle 3. Specifically, the detection module 9 includes a control board 19 electrically connected to the output end of the signal interface 8 and a wireless transmitting unit 20 integrated on the control board 19, the wireless transmitting unit 20 is wirelessly connected to a wireless receiving unit 21, the wireless transmitting unit 20 and the wireless receiving unit 21 are paired Bluetooth transmitting module and Bluetooth receiving module, the wireless receiving unit 21 is integrated in the control module 23 of the coffee machine 22, and the control module 23 is preferably a single chip microcomputer, which is coupled with a heater 31 for heating the built-in water tank (not shown) of the coffee machine 22 and a display panel 32 provided on the front side of the coffee machine 22. In this embodiment, when the waterproof signal connector 6 is docked with the signal interface 8, the temperature sensor 4 can send the measured temperature value to the control board 19, and the control board 19 transmits the received temperature value to the control module 23 through wireless transmission between the wireless transmitting unit 20 and the wireless receiving unit 21, so that the control module 23 can monitor the temperature inside the powder bowl body 1 in real time, and at the same time can send the temperature value to the display panel 32 for real-time display, and adjust the operating power of the heater 31 in time according to the preset temperature reference value, which can not only keep the temperature in the water tank at the optimal level, but also save electricity.

[0030] In order to ensure the battery life and operating stability of the control board 19 and related components, the control board 19 is integrated with a power supply unit 24 for powering the control board 19. The power supply unit 24 is preferably a lithium battery. The power supply unit 24 is electrically connected to a charging interface 25, and the charging interface 25 is a USB Type-C interface, so it has better compatibility and stability during charging.

[0031] In order to facilitate the maintenance of the control board 19, a mounting groove 26 for placing the control board 19 is provided on the handle 3. The signal transmission line 33 coupled to the output end of the signal interface 8 passes through the connecting rod 7 from the inside and extends into the mounting groove 26, and finally couples to the control board 19. In order to improve the convenience of charging, the charging interface 25 faces the opening of the mounting groove 26, so that it is convenient for the user to plug the charging line into the charging interface 25. The opening of the mounting groove 26 is covered with a cover 27, and the covering surface of the cover 27 is integrally provided with a sealing plug 34 that is inserted into the opening of the mounting groove 26 with interference fit, thereby improving the stability and sealing of the cover 27 when it is covered.

[0032] In order to realize the locking and unlocking of the connecting rod 7 and the pile head 2, buckle grooves 10 are provided on the upper and lower sides of the pile head 2 and near the handle 3. Buckle plates 11 are provided on the upper and lower sides of the connecting rod 7 and buckle in the two buckle grooves 10 respectively. The buckle plate 11 is provided with an elastic driving mechanism installed on the connecting rod 7 so that the buckle plate 11 can maintain a buckled state with the buckle groove 10 and a driving member that responds to an external trigger to overcome the elastic driving force of the elastic driving mechanism to drive the buckle plate 11 out of the buckle groove 10. In this embodiment, when the connecting rod 7 is connected to the pile head 2 so that the waterproof signal connector 6 is connected to the signal interface 8, the elastic driving mechanism can drive the buckle plate 11 to buckle in the corresponding buckle groove 10, thereby preventing the connecting rod 7 from being separated from the pile head 2.

[0033] On the contrary, when the connecting rod 7 is detached from the pile head 2 to separate the waterproof signal connector 6 from the signal interface 8, the elastic driving mechanism can drive the two snap-on plates 11 to engage with each other on the side of the connecting rod 7 away from the handle 3 to seal the signal interface 8, thereby protecting the signal interface 8.

[0034] Specifically, the elastic driving mechanism includes a connecting plate 12 vertically arranged at the rear end of the buckle plate 11, and a spring hinge 13 arranged between the end of the connecting plate 12 away from the buckle plate 11 and the connecting rod 7 so that the connecting plate 12 has a tendency to rotate and fit the surface of the connecting rod 7. The driving member is a pressing plate 14 arranged at the end of the connecting plate 12 away from the buckle plate 11 and inclined in a direction away from the connecting rod 7. One of the leaves of the spring hinge 13 is fixed to the surface of the connecting rod 7, and the other leaf is fixed to the plate surface of the pressing plate 14 close to the connecting rod 7.

[0035] In order to improve the stability of the buckle plate 11 after it is connected to the buckle groove 10, a locking groove 15 is provided on the plate surface of the buckle plate 11 close to the connecting rod 7. In this embodiment, when the buckle plate 11 is buckled in the buckle groove 10, the locking groove 15 can be buckled to the edge of the buckle groove 10 opening close to the connecting rod 7, so that one side of the locking groove 15 can abut against the side wall of the buckle groove 10, and the other side can be pressed against the upper surface of the pile head 2, so that the buckle plate 11 cannot be separated from the buckle groove 10, thereby improving the stability of the connecting rod 7 and the pile head 2 after they are connected.

[0036] In order to improve the lateral stability after the connecting rod 7 is connected to the pile head 2, positioning columns 16 are fixedly provided on the left and right sides of the pile head 2. The positioning columns 16 are arranged along the length direction of the pile head 2. Positioning seats 17 are fixedly provided on the left and right sides of the connecting rod 7. The positioning seats 17 are provided with positioning holes 18 for the positioning columns 16 to be inserted.

[0037] The specific usage process is as follows: When using the powder bowl, the handle 3 needs to be docked on the powder bowl body 1 first. When docking, first pinch the pressure plates 14 on both sides of the connecting rod 7 with your hands to overcome the elastic force of the spring hinge 13 to drive the buckle plates 11 on the two connecting plates 12 to open in opposite directions, so that the signal interface 8 on the connecting rod 7 is exposed. At this time, the connecting rod 7 and the pile head 2 are pre-positioned by the plug-in cooperation between the positioning column 16 and the positioning hole 18, and the signal interface 8 and the waterproof signal connector 6 are docked at the same time, thereby realizing the electrical connection between the temperature sensor 4 and the rear detection module 9. After the pre-positioning is completed, the two pressure plates 14 are released so that the two spring hinges 13 can respectively drive the buckle plates 11 on the two connecting plates 12 to buckle into the corresponding buckle grooves 10, and the locking grooves 15 on the buckle plates 11 are buckled to the opening edge of the buckle grooves 10 to complete the locking of the connecting rod 7 and the pile head 2, thereby completing the installation of the handle 3.

[0038] After the handle 3 is installed, the powder bowl body 1 filled with coffee powder is buckled to the brewing head 35 of the coffee machine 22 through the handle 3, and then the flavor substances in the coffee powder are extracted by high-temperature and high-pressure water. In this process, the temperature sensor 4 can directly detect the water temperature in the powder bowl body 1 through the heat conduction of the side wall of the powder bowl body 1, and send the measured water temperature value to the control board 19 of the installation slot 26 through the signal output line 5, the waterproof signal connector 6, the signal interface 8 and the signal transmission line 33 in sequence. The control board 19 then wirelessly transmits the temperature value to the wireless receiving unit 21 of the built-in control module 23 of the coffee machine 22 through the wireless transmitting unit 20, so that the control module 23 can monitor the water temperature in the powder bowl body 1 in real time and ensure the monitoring accuracy. At this time, the control module 23 can timely adjust the operating power of the built-in heater 31 of the coffee machine 22 according to the preset temperature threshold, so that the water temperature in the water tank (not shown) is kept at the best state and more power is saved. At the same time, the control module 23 can send the temperature value to the display panel 32 outside the coffee machine 22 for display, so that the user can intuitively understand the current brewing temperature of the coffee machine 22.

[0039] When the control board 19 is running, the power supply unit 24 can supply power to it, thereby ensuring stable operation. When the power supply unit 24 is running low on power, the cover 27 is opened to expose the mounting slot 26, so that the user can conveniently plug the charging cable connector (not shown) into the charging interface 25 of the control board 19, thereby charging the power supply unit 24 to maintain its battery life. After charging is completed, remove the charging cable and re-cover the cover 27 with the sealing plug 34 on the opening of the mounting slot 26.

[0040] When the powder bowl needs to be cleaned, first remove the powder bowl body 1 from the brewing head 35 of the coffee machine 22 through the handle 3. Then, pinch the pressure plates 14 on both sides of the connecting rod 7 by hand at the same time to overcome the elastic force of the spring hinge 13 to drive the buckle plates 11 on the two connecting plates 12 to disengage from the corresponding buckle grooves 10, thereby releasing the lock between the connecting rod 7 and the pile head 2. At this time, remove the handle 3 from the connecting rod 7 so that the positioning hole 18 on the positioning seat 17 is disengaged from the positioning column 16, and the handle 3 can be removed from the powder bowl body 1, and the signal interface 8 and the waterproof signal connector 6 are separated at the same time. In this state, the removed powder bowl body 1 can be washed separately without worrying about the waterproof problem of the detection module 9 on the handle 3. Since the temperature sensor 4 and the waterproof signal connector 6 on the powder bowl body 1 have been fully waterproofed, there will be no water ingress problem. The next time you use it, just dry the waterproof signal connector 6. At the same time, when the pressure plate 14 is released, the two spring hinges 13 can respectively drive the snap-on plates 11 on the two connecting plates 12 to engage with each other, thereby forming a barrier on the side of the connecting rod 7 away from the handle 3 to protect the signal interface 8 and thus extend its service life.

[0041] In order to facilitate users to view the temperature value measured by the temperature sensor 4, the wireless transmitting unit 20 is wirelessly connected to at least one wireless display terminal 29 to receive and display the temperature value measured by the temperature sensor 4. The wireless display terminal 29 is preferably a display screen or touch screen with a Bluetooth receiving function, and can also be a mobile phone, tablet computer, etc., so as to facilitate users to remotely view the temperature value measured by the temperature sensor 4, or facilitate the teaching of the coffee machine 22, which is more humane. Example

[0042] like Fig.12As shown, on the basis of the first embodiment, a pressure sensor 28 is further provided on the inner wall of the powder bowl body 1 at a position corresponding to the pile head 2, and the pressure sensor 28 is sealed and connected to the connection between the powder bowl body 1. Specifically, the inner wall of the powder bowl body 1 is provided with an installation port 36 for installing the pressure sensor 28, and a sealant is filled between the installation port 36 and the pressure sensor 28 to achieve a waterproof seal. The signal output line 5 of the pressure sensor 28 passes through the pile head 2 and is electrically connected to the waterproof signal connector 6. When the waterproof signal connector 6 is connected to the signal interface 8 on the connecting rod 7, the pressure sensor 28 can be electrically connected to the detection module 9 at the rear, thereby realizing the detection of the extraction pressure in the powder bowl body 1 and ensuring the detection accuracy.
