DETAILED DESCRIPTION

[0025] 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.

[0026] Please refer to Figure 1-4 ;

[0027] The water-boiling base described in the utility model has a weighing function, and its core component is a pressure sensor 3, which is a consumable part, and is intended to reduce the difficulty of maintenance; it specifically includes a base body 1 and a support plate 21, wherein the base body 1 should have the water-boiling function and water-supply function of similar products on the market, that is, it has parts such as a controller, a coupler and a water pump. For details, reference can be made to relevant documents in the prior art. At least one pressure sensor 3 is installed at the bottom of the base body 1. In this embodiment, the bottom of the base body 1 refers to the bottom surface of the lower shell 12, and the pressure sensor 3 can be close to the inner side or the outer side of the lower shell 12, which is not limited here. When the pressure sensor 3 is arranged on the inner side of the lower shell 12, a hole for the abutment 22 to penetrate should be provided at the position corresponding to the pressure sensor 3. If the pressure sensor 3 is arranged on the outer side, the abutment 22 does not need to pass through the lower shell 12 to directly contact it, but a hole for the wire of the pressure sensor 3 to pass through should be provided;

[0028] In addition, when there is one pressure sensor 3, a pressure sensor 3 with a larger volume and a larger load-bearing capacity should be selected, and when there are multiple pressure sensors, preferably four, since the force is dispersed, a pressure sensor 3 with a smaller volume can be selected;

[0029] During normal use, the support plate 21 is placed under the base body 1 so that the abutment portion 22 abuts against the pressure sensor 3. When the water in the kettle increases or decreases, the deformation of the pressure sensor 3 changes, thereby generating different data to be input into the controller.

[0030] Assuming that the pressure sensor 3 is installed on the inner side of the lower shell 12, when maintenance is required, it is only necessary to remove the lower shell 12 at the bottom of the base body 1 to expose all the pressure sensors 3, and then perform maintenance and replacement. Based on this solution, fewer parts need to be removed during maintenance;

[0031] Assuming that the pressure sensor 3 is installed on the outside of the lower shell 12, there is no need to disassemble the base body 1 when maintenance is required. The pressure sensor 3 can be directly removed, the pressure sensor 3 to be replaced can be disconnected from the wire, and the new pressure sensor 3 can be reconnected to the wire. Finally, the pressure sensor 3 can be fixed to the lower shell 12, which makes maintenance faster.

[0032] No matter the pressure sensor 3 is arranged on the inside or outside, only a few parts need to be removed, and it will not interfere with other parts inside the base body 1, so the maintenance is very convenient and quick.

[0033] In the prior art, a base body 1 usually has only one water supply detection mode. If the pressure sensor 3 is damaged and not repaired, the automatic water supply function of the water-boiling base is relatively scrapped. The pressure sensor 3 is a consumable part and needs to be mailed or repaired to a professional after-sales center, which is troublesome. Therefore, another embodiment is provided;

[0034] The base body 1 itself has a manual or / and automatic water filling function. It should be noted that the water filling referred to in the article has automatic water filling and / or automatic water stopping steps, that is to say, the base body 1 can be used normally when it is not equipped with a support plate 21. When the base body 1 itself has only manual functions, after the support plate 21 is installed, the data measured by the resistance part 22 and the pressure sensor 3 control the water filling component of the base body 1 itself, and achieve the effect of weighing control of water filling. If the water filling kettle has an automatic water filling function, for example, it can be a liquid level gauge or a method of limiting the water filling time to prevent overflow, etc., after the support plate 21 is installed, the weighing program can be triggered to shield the original automatic detection control module, and the water filling component of the base body 1 itself is controlled by the data measured by the resistance part 22 and the pressure sensor 3, and the effect of weighing control of water filling is achieved.

[0035] In this embodiment, a weighing detection control module is provided in the controller of the base body 1. Before the support plate 21 is connected, that is, the abutment 22 is not in contact with the pressure sensor 3, the pressure sensor 3 is preset with a trigger threshold value, which is the weight of the base body 1 and the empty kettle body. When the abutment 22 is not in contact with the pressure sensor 3, the value of the pressure sensor 3 will be lower than the threshold value. At this time, there is no data input by default. The weighing detection control module located inside the base body 1 is always electrically connected to the microprocessor, but there is no data input. At this time, the original automatic detection control module is used. It is assumed that the automatic detection control module is a water level The detection control module is used in the following ways: the lowest water level is detected by the water level detection control module, and then the automatic water filling effect is realized. Then, the action time of the water supply component is limited by the timer to limit the water filling amount to avoid overflow. After the base body 1 is connected with the support plate 21, that is, the abutment part 22 is in contact with the pressure sensor 3, the water in the kettle body is completely emptied and placed on the base body 1, and then the power is turned on. At this time, the data obtained by the pressure sensor 3 reaches the preset threshold, and 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;

[0036] In the initial state, the data tested by the pressure sensor 3 is the weight of the base body 1 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 base body 1" or "CN116807230A, a base body 1 weighing water injection calibration method", or refer to other technical documents in the prior art that use weighing water injection;

[0037] If there is no data input to the logic judgment module after the support plate 21 is removed, the microprocessor will re-enable the water level detection control module to restore the initial use state.

[0038] In the embodiment of the utility model, the pressure sensor 3 includes an outer frame 31 with a hollow middle part, a deformation part 32 connected to the outer frame 31 is provided at the hollow part, a plurality of card slots 33 are provided in the deformation part 32, and the resistance part 22 includes a supporting block 221 adapted to the deformation part 32, and a plurality of card blocks 222 cooperating with the card slots 33 are provided on the supporting block 221. When installing, the supporting block 221 abuts against the bottom of the deformation part 32, and the card block 222 is inserted into the card slot 33. In this way, displacement between the resistance part 22 and the pressure sensor 3 can be avoided, which may cause inaccurate measurement data. Preferably, a pressure sensor 3 with model: CZL928NB can be used in this embodiment.

[0039] In the embodiment of the utility model, a latch 13 is provided on the outer side of the base body 1, and the latch 13 is used to fix the pressure sensor 3. Its specific implementation methods include inner concave and outer convex, that is, the bottom surface of the lower shell 12 is recessed inward to form a groove, and the latch 13 is set therein, while the outer convex is that a plurality of blocks 222 are set on the bottom surface of the lower shell 12 to form the latch 13. The latch 13 in this embodiment fixes the outer frame 31 so that the deformation part 32 is suspended in the latch 13. An opening is provided on one side of the latch 13. During the installation process, no screws or other fixing parts are required to fix the pressure sensor 3. It only needs to be inserted into the latch 13. When the pressure sensor 3 needs to be replaced, it only needs to be pushed out of the opening with force, which makes maintenance more convenient and quick.

[0040] Based on the above embodiment, the locking position 13 is protruding from the base body 1, and a surrounding edge 23 is provided on the support plate 21. The surrounding edge 23 surrounds the outer periphery of the locking position 13 to play a waterproof role; in addition, when there are four pressure sensors 3, they are symmetrically arranged at the four corners of the base body 1. At this time, the surrounding edge 23 can enclose a long space to enclose the two locking positions 13 on the same side, and the same is true for the other side.

[0041] Preferably, the surrounding edge 23 also has a limiting function. The deformation of each pressure sensor 3 is limited. In order to avoid damage to the pressure sensor 3 due to excessive deformation, the distance between the upper end surface of the surrounding edge 23 and the bottom surface of the lower shell 12 is between 0.5mm and 1mm, that is, the base body 1 can only float downward as a whole by 0.5mm to 1mm, so that it will not exceed the deformation of the pressure sensor 3.

[0042] In addition, when the base body 1 is used alone, the protruding latching position 13 can also be used as a supporting foot, and a flat surface such as a desktop will not contact the pressure sensor 3.

[0043] In the embodiment of the utility model, a water supply method is adopted from the bottom, and a water supply component is provided at the coupler. During use, water may be sprinkled into the coupler and then enter the interior of the base body 1. Therefore, a drainage hole 14 is provided at the bottom of the base body 1 corresponding to the position of the coupler, and the water entering the interior of the base body 1 can flow out from the drainage hole 14.

[0044] In the embodiment of the utility model, the base body 1 includes an upper shell 11 and a lower shell 12, and a panel 15 is provided in the upper shell 11 at a position corresponding to the coupler, and a water inlet joint 17 is located in the space enclosed by the panel 15. The lower shell 12 is provided with a panel 2 16, and the panel 2 16 is arranged around the outer periphery of the panel 15, which is equivalent to the panel 2 16 being sleeved on the outer periphery of the panel 15. The drainage hole 14 is arranged in the space of the panel 2 16, and the connection between the external water pipe and the water inlet joint 17 is located inside the panel 15. If the water inlet joint 17 leaks, or water enters from the outside through the coupler, it will directly fall into the space enclosed by the panel 2 16 under the action of the panel 15 and the panel 2 16, and then flow out from the drainage hole 14, so as to prevent water from entering other positions of the base body 1 and damaging other electronic components.

[0045] In the embodiment of the utility model, a movable structure is provided between the base body 1 and the support plate 21 for limiting the movable distance between the two, that is, the support plate 21 and the base body 1 are movable, reserving space for the deformation of the pressure sensor 3, and at the same time, the support plate 21 is separated from the base body 1 through the movable structure.

[0046] More specifically, the movable structure includes at least two "Z"-shaped movable buckles 41, one end of the movable buckle 41 is connected to the bottom of the base body 1, and a buckle portion 43 is provided on the support plate 21, and the other end of the movable buckle 41 can be in contact with the buckle portion 43. When in a flat state or in use state, the lower end of the movable buckle 41 does not contact the buckle portion 43, and after the base body 1 is lifted up a certain distance, the lower end of the movable buckle 41 is in contact with the buckle portion 43 to prevent the support plate 21 from separating from the base body 1; in addition, the movable buckle 41 is connected to the lower shell 12 by screws, which is convenient for disassembly and maintenance. In addition, a through hole 42 is provided on the support plate 21 to act as a drain.

[0047] In an embodiment of the utility model, a wire management member 24 is provided on the support plate 21 near the wire outlet position of the base body 1. The wires referred to in this embodiment include electric wires and water pipes. The wire management member 24 has multiple implementation methods. For example, it can be configured as a buckle to buckle and fix the electric wires and the water pipes, or it can form a baffle that is opposite to the wire outlet position so that the wires and the water pipes are bent at 90° and then led out along the horizontal extension direction of the wire management member 24. Preferably, a buckle is provided on the wire management member 24 to fix the wires and the water pipes.
