In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.
A first embodiment of the present invention relates to a water storage apparatus, as shown in fig. 1, including: the cup body 11, the sleeve 12, the capacitance detection chip 13 and the controller 14 connected with the capacitance detection chip 13; a plurality of induction capacitor strips 15 are arranged on the outer wall of the cup body 11, the induction capacitor strips 15 extend along the circumferential direction of the cup body 11, and the induction capacitor strips 15 are sequentially arranged along the height direction of the cup body 11; the cup body 11 is sleeved in the sleeve 12, a reference capacitance strip 16 is arranged on the outer wall 121 of the sleeve 12, and the reference capacitance strip 16 extends along the circumferential direction of the sleeve 12; the sensing capacitor strips 15 and the reference capacitor strips 16 are electrically connected with the capacitor detection chip 13, and the capacitor detection chip 13 is used for detecting respective detection capacitance values of the sensing capacitor strips 15 and reference capacitance values of the reference capacitor strips 16 and sending the detection capacitance values to the controller 14; the controller 14 is configured to output prompt information for indicating the current water level according to the detected capacitance value and the reference capacitance value.
Specifically, the capacitance detection chip 13 is located between the cup body 11 and the sleeve 12, and the water storage device may further include: a groove penetrating the wall of the sleeve 12 and a conductive part connecting the reference capacitor strip 16 and the capacitance detection chip 13; the groove comprises a first side wall 17 for attaching the conductive part, the sleeve 12 comprises an outer wall 121 and an inner wall which are oppositely arranged, and the first side wall 17 is connected with the outer wall 121 and the inner wall and forms an obtuse angle with the outer wall 121. Because the first side wall 17 is used for attaching the conductive part and the included angle between the first side wall and the outer wall 121 is an obtuse angle, the attachment of the conductive part is facilitated, the service life of the reference capacitor strip 16 is prolonged, and the risk that the reference capacitor strip 16 falls off is reduced.
Optionally, at least one mounting groove 18 may be formed in the sleeve 12, the mounting groove 18 penetrates through a side wall of the sleeve 12, optionally, the number of the mounting grooves 18 is the same as the number of the induction capacitor strips 15, and each induction capacitor strip 15 is accommodated in one mounting groove 18, and certainly, a plurality of induction capacitor strips 15 may also be accommodated in one mounting groove 18, which is not limited herein. So set up, avoided leading to the too big problem in gap between sleeve 12 and the cup 11 because of reserving space installation response electric capacity strip 15, simultaneously, can overlap sleeve 12 earlier on cup 11, install response electric capacity strip 15 in mounting groove 18 again and attached on cup 11, it is more convenient to assemble.
It can be understood that, the mounting groove 18 can also be a recessed portion recessed from the inner wall of the sleeve 12 toward the outer wall 121 of the sleeve without penetrating through the side wall of the sleeve 12, in the assembling process, the inductive capacitor strip 15 can be attached to the cup body 11 first (at this time, the inductive capacitor strip 15 abuts against and is held between the cup body 11 and the sleeve 12, the groove is spread, the space enclosed by the sleeve 12 becomes larger), and then the position of the sleeve 12 is adjusted, so that the inductive capacitor strip 15 is clamped into the mounting groove 18 (at this time, the groove is restored to the original state, and the gap between the cup body 11 and the sleeve 12 is smaller).
In practical applications, the water storage apparatus may further include a housing (not shown) sleeved on the sleeve 12, and the capacitance detection chip 13 is electrically connected to the housing, that is, the sensing capacitance strip 15 or the reference capacitance strip 16 serves as one pole of a capacitor, and the other pole of the capacitor is in the capacitance chip and grounded via the housing, in other words, one pole of the capacitor is the sensing capacitance strip 15 or the reference capacitance strip 16, the other pole is water in the cup 11, and an insulating medium of the capacitor is a sidewall of the cup 11. So set up, can avoid external metal to the influence that detects capacitance value and reference capacitance value to improve the accuracy that detects.
Specifically, in the height direction of cup 11, reference capacitor bar 16 is located below a plurality of induction capacitor bars 15 and is aligned with each of the plurality of induction capacitor bars 15.
Further, the water storage device may further include a water outlet groove (not shown) for discharging water when pouring water, the water outlet groove may be disposed on the cup body 11 and the housing, and the cup body 11 may include: being close to the first side of play basin and the second side that sets up with first side relative in radial direction, induction capacitance strip 15 and/or benchmark capacitance strip 16 are located the second side, promptly, go out the basin and keep away from induction capacitance strip 15 and benchmark capacitance strip 16 setting, so set up, when can avoiding pouring tea, tealeaves adhesion on the lateral wall at induction capacitance strip 15 and/or benchmark capacitance strip 16 place, and influence the problem of the accuracy that detects.
In this embodiment, the quantity of sensing capacitance strip 15 is two, and a sensing capacitance strip 15 is located 11 high half departments of cup, and another sensing capacitance strip 15 is located 11 high two-thirds departments of cup to whether the detection water level that can be accurate reaches 11 high half departments of cup and two-thirds department, demand to the water yield when can be better being adapted to making tea.
In order to ensure that the inductive capacitance strips 15 and the reference capacitance strips 16 have sufficient capacitance judgment areas, the lengths (the circumferential dimension of the cup body) of the capacitance strips (the inductive capacitance strips 15 and/or the reference capacitance strips 16) may be set to be larger due to the influence of the height of the water storage device, but the capacitance strips may not avoid one side of the water outlet groove due to too large length, so that tea leaves are attached to one side of the capacitance strips, and therefore, in the present embodiment, the lengths of the capacitance strips are set to be 45mm (millimeters) -60mm, the widths (the height dimension of the cup body, that is, the axial dimension) of the capacitance strips are set to be 1mm-10mm, preferably, the lengths of the capacitance strips are 50mm, so as to meet the above requirements.
In practical application, the inductive capacitor strip 15 is fixed on the outer wall of the cup body 11 via a back adhesive (not shown), and/or the reference capacitor strip 16 is fixed on the outer wall 121 of the sleeve 12 via a back adhesive, the thickness of the back adhesive is 0.08 mm to 0.12 mm, preferably, the thickness of the back adhesive is 0.1 mm, so that the viscosity of the back adhesive is ensured, and the problem that the detection error of the inductive capacitor strip 15 or the reference capacitor strip 16 is too large due to too large thickness of the back adhesive can be avoided, wherein the back adhesive can be a heat-resistant back adhesive, so that the viscosity of the back adhesive can be prevented from being reduced due to high temperature, and the requirement on the viscosity cannot be met, for example, GTM715B is provided, the back adhesive can be used for suspending 500 g under a heavy object at 70 ℃, can be kept for more than or equal to 5000 minutes, and can be used for suspending 1000 g of a heavy object at room temperature, and can be kept for more than or equal.
Wherein, water storage equipment can be kettle, teapot, drinking cup etc. and the material of cup 11 can be plastics, glass, pottery, nonmetal material such as red porcelain, and the material of induction capacitance strip 15 and benchmark capacitance strip 16 can be metal material such as copper foil, aluminium foil, and the material of sleeve 12 can be nonmetal material such as plastics, glass, pottery, red porcelain, and the material of shell can be metal material such as copper, aluminium, iron.
In practical application, the water storage device may use a reference capacitance method and a calibration method to detect the water level, which are as follows:
for the reference capacitance method, a capacitance threshold can be directly set, and the threshold is usually between 0-1 pf.
In the using process, the capacitance detection chip 13 is used to obtain the reference capacitance value of the reference capacitance strip 16 and the respective actual capacitance values of the multiple sensing capacitance strips 15, and then the controller 14 is used to determine whether the difference value between the actual capacitance value of each sensing capacitance strip 15 and the reference capacitance value reaches the corresponding capacitance threshold value, wherein each sensing capacitance strip 15 corresponds to one capacitance threshold value, and after determining that the difference value between the maximum value (assumed as the actual capacitance value of the ith sensing capacitance strip 15) and the reference capacitance value of the actual capacitance values of the multiple sensing capacitance strips 15 reaches the capacitance threshold value (the ith capacitance threshold value) corresponding to the sensing capacitance strip 15, prompt information for representing that the current water level reaches the sensing capacitance strip 15 (the ith sensing capacitance strip 15) is output.
Optionally, after determining that the difference between the actual capacitance value of the ith sensing capacitor strip 15 and the reference capacitance value reaches the ith capacitance threshold, the controller 14 may further include: and respectively judging whether the difference value between the actual capacitance value of the (i-1) th induction capacitance strip 15 and the reference capacitance value reaches the (i-1) th capacitance threshold value, if so, executing the step of outputting prompt information for representing that the current water level reaches the (i) th induction capacitance strip 15. Through comparison between the maximum value (assumed as the actual capacitance value of the ith induction capacitance strip 15) in the actual capacitance values and the capacitance threshold value (the ith capacitance threshold value) corresponding to the induction capacitance strip 15 and comparison between the actual capacitance value of the (i-1) th induction capacitance strip 15 and the (i-1) th capacitance threshold value, the condition that the two conditions are simultaneously met is determined that the water level reaches the induction capacitance strip 15 corresponding to the maximum value in the actual capacitance values, and the accuracy is improved.
For example, the number of the sensing capacitor strips 15 is two, one sensing capacitor strip 15 is located at one-half of the height of the cup body 11, the other sensing capacitor strip 15 is located at two-thirds of the height of the cup body 11, and after the actual capacitance value of the sensing capacitor strip 15 located at the two-thirds of the height of the cup body 11 reaches the first capacitance threshold value, it is also necessary to determine that the actual capacitance value of the sensing capacitor strip 15 located at the one-half of the height of the cup body 11 reaches the second capacitance threshold value, and then the actual capacitance value can be output to represent that the current water level reaches the two-thirds of the height of the cup body 11.
For the calibration method, calibration before leaving the factory needs to be performed, which specifically comprises the following steps: respectively acquiring respective first reference capacitance values of the plurality of induction capacitance strips 15 in an empty cup state by using the capacitance detection chip 13, taking the first reference capacitance values as reference capacitance values, and setting a reference capacitance range according to the first reference capacitance values, for example, the first reference capacitance value is 10C, and the reference capacitance range can be set to 11C-12C; and when the water level in the water storage device is obtained to be consistent with the height of each induction capacitance strip 15 in the process of continuously pouring water into the water storage device by using the capacitance detection chip 13, the measured capacitance value of the induction capacitance strip 15 consistent with the height of the water level and the first reference capacitance value of the reference capacitance strip 16 are obtained, and the capacitance threshold value corresponding to each induction capacitance strip 15 is determined according to the measured capacitance value, the reference capacitance value and the first reference capacitance value of each induction capacitance strip 15.
In the using process, in the empty cup state, the capacitance detection chip 13 is used to obtain the second reference capacitance values of the plurality of sensing capacitor strips 15 in the empty cup state again, and if the second reference capacitance values exceed the reference capacitance range for a plurality of times, the reference capacitance values are reset according to the second reference capacitance values. For example, the reference capacitance range is 11C-12C, and if the second reference capacitance value reaches 13C 5 times, 13C is used as a new reference capacitance value, and the capacitance threshold value corresponding to each sensing capacitor strip 15 is re-determined according to the measured capacitance value, the new reference capacitance value, and the first reference capacitance value of each sensing capacitor strip 15, and by continuously updating the reference capacitance value in the using process to re-determine the capacitance threshold value corresponding to each sensing capacitor strip 15, errors caused by aging and other factors can be eliminated.
The capacitance detection chip 13 is used for obtaining respective actual capacitance values of the plurality of induction capacitance strips 15 in the use state and a second reference capacitance value of the reference capacitance strip 16, and the controller 14 is used for outputting prompt information for representing that the current water level reaches the ith induction capacitance strip 15 after determining that the difference value between the actual capacitance value of the ith induction capacitance strip 15 and the second reference capacitance value reaches the ith capacitance threshold value. Because the first reference capacitance value is considered in the setting of the capacitance threshold value, the second reference capacitance value is used in the determination process, thereby eliminating the influence of factors such as water vapor attached between the cup body 11 and the sleeve 12 in the use process and improving the accuracy.
Optionally, after the controller 14 determines that the difference between the actual capacitance value of the ith sensing capacitor bar 15 and the second reference capacitance value and the difference between the second reference capacitance value and the ith reference capacitance value reach the ith capacitance threshold, the method may further include: calculating the change rate of the actual capacitance value of the ith induction capacitance strip 15; and after the change rate of the actual capacitance value is judged to be larger than or equal to the capacitance change rate threshold value, outputting prompt information for representing that the current water level reaches the ith induction capacitance strip 15. By judging the magnitude relation between the actual capacitance value change rate and the capacitance change rate threshold value, the misjudgment caused by the floating of the detection value and the misjudgment caused by shaking of the water storage equipment can be eliminated, the judgment is carried out by utilizing the capacitance threshold value and the capacitance change rate, and the accuracy is improved.
The steps of the above methods are divided for clarity, and the implementation may be combined into one step or split some steps, and the steps are divided into multiple steps, so long as the same logical relationship is included, which are all within the protection scope of the present patent; it is within the scope of the patent to add insignificant modifications to the algorithms or processes or to introduce insignificant design changes to the core design without changing the algorithms or processes.

A second embodiment of the present invention relates to a water storage apparatus, as shown in fig. 2. The second embodiment is substantially the same as the first embodiment, and mainly differs therefrom in that: in the second embodiment of the present invention, a plurality of auxiliary capacitor bars 19 are further disposed on the outer wall of the cup body 11, and the plurality of auxiliary capacitor bars 19 are electrically connected to the capacitance detection chip 13; the auxiliary capacitor bars 19 are arranged in pairs with the sensor capacitor bars 15, and the auxiliary capacitor bars 19 in each pair are at the same height as the sensor capacitor bars 15. Only by simultaneously satisfying the conditions through a pair of equal-height capacitor bars, the water level is determined to reach the height, so that misjudgment caused by the inclination of the water storage equipment is avoided, and the accuracy of water level detection is further improved.
