DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] Please refer to Figure 1-6 ;

[0028] The weighing accessory described in the utility model is applied to the water supply base of the kettle, and the weighing accessory cooperates with the program to control the water supply component of the kettle base 42 to realize the weighing and water supply function; it specifically includes an accessory base 1, and the accessory base 1 is provided with at least one pressure sensor 21, and the pressure sensor 21 is electrically connected to a communication port 1 31; the kettle base 42 used in combination with the weighing accessory described in the utility model should be provided with a communication port 2 5 connected to the communication port 1 31.

[0029] The kettle base 42 itself has a manual or / and automatic water supply function. It should be noted that the water supply referred to in the text has automatic water filling and / or automatic water stop steps, that is to say, the kettle base 42 can be used normally when it is not equipped with a weighing accessory. When the kettle base 42 itself has only a manual function, after installing the weighing accessory, the water supply component of the kettle base 42 itself can be controlled by the data measured by the weighing accessory, thereby achieving the effect of weighing control of water supply. If the water supply kettle has an automatic water supply function, for example, it can be a liquid level meter or a method of limiting the water filling time to prevent overflow, etc., after installing the weighing accessory, the weighing program can be triggered, the original automatic detection control module is shielded, and the water supply component of the kettle base 42 itself is controlled by the data measured by the weighing accessory, thereby achieving the effect of weighing control of water supply.

[0030] The weighing accessory in the present invention may include a weighing detection control module and an independent power supply, or the weighing detection control module may be integrated into the kettle base 42, and the pressure sensor 21 may communicate with the weighing detection control module through the communication port to realize data transmission, and the communication port may also be used to supply power to the pressure sensor 21;

[0031] It is preferred to integrate the weighing detection control module into the kettle base 42. Since the weighing detection control module is mostly implemented through a chip program, it does not occupy too much space inside the kettle base 42, and there is no need to add a circuit board and a chip to the weighing accessory, making the weighing accessory simpler to manufacture and lowering the cost. The following is an explanation of the usage:

[0032] First, place the accessory base 1 on a flat surface, then power off the kettle base 42, connect the communication port 1 31 with the communication port 2 5, and use the positioning structure on the accessory base 1 to limit the position of the kettle base 42. At the same time, the pressure sensor 21 contacts the bottom of the kettle base 42. It should be noted that the positioning structure only limits the horizontal position of the kettle base 42, and it can also move longitudinally to apply pressure to the pressure sensor 21. Then, completely empty the water in the kettle body 41 and place it on the kettle base 42. This completes the installation and assembly process;

[0033] To further illustrate, the position of the communication port 2 5 on the kettle base 42 is fixed, while the communication port 1 31 has two configuration modes;

[0034] In the first mode, the communication port 1 31 is a free movable end, and the pressure sensor 21 is electrically connected to the communication port 1 31 through a lead wire, so that the communication port 1 31 can move freely, so as to adapt to any position of the communication port 2 5 set on the kettle base 42. It should be noted that the influence of the pulling of the test wire on the pressure sensor 21 is very slight and can be ignored here;

[0035] In the second mode, the communication port 1 31 is movably mounted on the accessory base 1, that is, the communication port 1 31 can move longitudinally. When the communication port 1 31 is connected to the communication port 2 5, the communication port 1 31 can move longitudinally along with the kettle base 42.

[0036] Of course, the weight of communication port 31 should be added to the measurement range of the weighing detection control module.

[0037] Take the weighing detection control module integrated into the kettle base 42 as an example for further explanation, Figure 6 ;

[0038] Before the weighing accessories are connected, the weighing detection control module located inside the kettle base 42 always maintains electrical connection with the microprocessor, but there is no data input. At this time, the original automatic detection control module is used. Assuming that the automatic detection control module is a water level detection control module, its use method is: the water level detection control module detects the lowest water level, and then realizes the automatic water filling effect, and then limits the action time of the water supply component through the timer to limit the water filling amount to avoid overflow; when the kettle base 42 is connected to the weighing base through the communication port, the water in the kettle body 41 is completely emptied and placed on the kettle base 42, and then the power is turned on, and the pressure sensor 21 is powered through the communication port. At this time, the pressure sensor 21 has data input to the weighing detection control module and the logic judgment module through the communication port. The logic judgment module sends a signal to the microprocessor to confirm that the weighing data has been input. At this time, the microprocessor shields the water level detection control module and uses the weighing detection control module for control;

[0039] In the initial state, the data tested by the pressure sensor 21 is the weight of the kettle base 42 plus the weight of the empty kettle, and this data is used as the basic value. The specific weighing detection control module can refer to the relevant module description of the public patent document "CN220045587U, a calibrable weighing kettle base 42" or "CN116807230A, a weighing and water filling calibration method for a kettle base 42", or refer to other technical documents in the prior art that use weighing water filling;

[0040] If there is no data input to the logic judgment module after the weighing accessories are removed, the microprocessor will re-enable the water level detection control module and restore the initial use state.

[0041] The utility model can expand the water supply method of the kettle base 42 by means of an external weighing accessory, realize two water supply methods for users to choose, and is easy to disassemble and assemble, has a very simple structure, and has a low manufacturing cost;

[0042] In addition, the weighing water filling method is a new technology, but it is basically built into the kettle base 42, and the pressure sensor 21 is a wearing part. The built-in method will cause maintenance difficulties. The utility model adopts an external method with a very simple structure, and both the maintenance cost and maintenance time can be reduced to a minimum.

[0043] Based on the above implementation mode, the microprocessor is also electrically connected to a detection timer. When the water supply component is activated, the detection timer starts timing synchronously. If the pressure sensor 21 is damaged, the weighing and water supply will be inaccurate, which may cause excessive water injection and overflow. At this time, the water injection time of the water supply component is limited by the detection timer. In addition, when the detection timer expires, the data detected by the pressure sensor 21 is inconsistent with the preset data, or there is a large deviation, the weighing detection control module will issue an alarm. It may be that the pressure sensor 21 is broken or there is no water, which can effectively remind the user.

[0044] One embodiment of the pressure sensor 21 of the utility model is as follows: Figure 2 and Figure 3 , specifically including a bottom plate 11, a plurality of through holes 12 are provided on the bottom plate 11, and the through holes 12 correspond to the supporting feet 43 of the kettle base 42 respectively, and the pressure sensor 21 is arranged at the through holes 12. Preferably, the pressure sensor 21 is arranged on the bottom surface of the bottom plate 11. When installed, the supporting feet 43 of the kettle base 42 pass through the through holes 12 and abut against the pressure sensor 21. At the same time, the plurality of through holes 12 and the supporting feet 43 are combined to form a positioning structure. Of course, a bottom cover 13 is fixedly provided on the bottom surface of the bottom plate 11, for example, it can be fixed with screws, and the bottom cover 13 is used to cover the pressure sensor 21, and there is a gap between the bottom plate 11 and the bottom cover 13.

[0045] Preferably, the cross-sectional area of ​​the support foot 43 is slightly smaller than the aperture of the through hole 12, and a slot 22 is provided on each pressure sensor 21, and the end of the support foot 43 can be embedded in the slot 22 and directly contact the pressure sensor 21, thereby reducing friction.

[0046] Another embodiment of the utility model regarding the arrangement of the pressure sensor 21; Figure 4 and Figure 5 , specifically including a bottom plate 11, a positioning block 14 is provided at the center position of the bottom plate 11 corresponding to the kettle base 42, a positioning groove 44 adapted to the positioning block 14 is provided at the bottom of the kettle base 42 to form a positioning structure, preferably, the area of ​​the positioning groove 44 is slightly larger than the cross-sectional area of ​​the positioning block 14, a pressure sensor 21 is installed in the middle of the surface of the positioning block 14, the pressure sensor 21 in this embodiment has one, which is against the bottom of the positioning groove 44, of course, a bottom cover 13 is fixed on the bottom surface of the bottom plate 11, for example, it can be fixed with screws, there is a gap between the bottom plate 11 and the bottom cover 13, and the guide for connecting the pressure sensor 21 with the communication port 31 can be arranged from the gap.

[0047] Preferably, a support plate 23 is fixedly provided on the surface of the pressure sensor 21 , and the support plate 23 is adapted to the shape of the positioning groove 44 , so that it can play a positioning role and reduce friction at the same time.

[0048] It should be noted that the kettle base 42 using this method does not have the supporting feet 43 , or the ends of the supporting feet 43 do not contact the bottom plate 11 .

[0049] In the embodiment of the utility model, the base plate 11 is provided with a mounting opening 15, and the communication port 31 is provided with a flange 32 along the circumferential direction, and the flange 32 is abutted against the outer periphery of the mounting opening 15. With the flange 32 as the boundary, the lower part of the communication port 31 can pass through the mounting opening 15 from the surface of the base plate 11 to the other side. Of course, the shape of the mounting opening 15 is adapted to the shape of the part through which the communication port 31 passes, but the area of ​​the mounting opening 15 is larger than the area of ​​the lower part of the communication port 31, so that there is almost no friction when the two move relative to each other.

[0050] Preferably, the communication port 1 31 is provided with a flange 2 33 along the circumference direction, and a slot 34 is formed between the flange 2 33 and the flange 1 32. The slot 34 is movably engaged with the edge of the mounting port 15 to prevent the communication port 1 31 from being pulled out, and forms a whole with the accessory base 1. It should be noted that after the communication port 1 31 is connected to the communication port 2 5, the communication port 1 31 can move up and down relative to the mounting port 15.

[0051] In the embodiment of the utility model, two limiting plates 16 are provided at opposite positions on the surface of the accessory base 1. The space formed by the two limiting plates 16 is slightly larger than the width of the kettle base 42 and is used to limit its horizontal position.

[0052] Furthermore, the communication port 1 is installed on the accessory base 1, and a fixing block 17 is installed on the accessory base 1. The fixing block 17 is provided with a fixing groove 18 for fixing a water pipe and / or a wire. One side of the fixing block 17 is close to one side of the kettle base 42, forming a limit with the communication port 1 31.
