Referring to fig. 1 to 7, a cup cover 100 for measuring water intake is provided according to an embodiment of the present invention. The cup cover 100 capable of measuring water intake comprises a cover body 1, a suction pipe 2, a first induction ring 31, a second induction ring 32, a battery 4 and a PCB control board 5.

Wherein, the cover body 1 can be covered at the cup opening d of the cup body 200 or matched with other containers for containing water. The cover 1 has a housing cavity b inside for assembling various components. Specifically, the cover 1 includes a top cover 11 and a cover seat 12 that are closed to form the accommodating chamber b. The straw 2 is arranged in the cover body 1 in a penetrating way, and the lower end of the straw 2 can extend into the cup body 200 and comprises a connecting section 22 positioned in the accommodating cavity b.

The PCB control board 5 is provided in the accommodation chamber b and is integrated with the flow rate calculation chip 51. Specifically, the cover seat 12 has an annular step surface a on which the PCB control board 5 is fitted and erected. The flow rate calculation chip 51 is a prior art, and is not developed too much here. The battery 4 is disposed in the accommodating cavity b and electrically connected with the PCB control board 5 for supplying power to the PCB control board 5. The first sensing ring 31 and the second sensing ring 32 are sleeved on the connecting section 22 at intervals and are electrically connected with the PCB control board 5, and are used for sensing and generating sensing signals at the corresponding positions of the water flow passing through the suction pipe 2 and transmitting the sensing signals to the PCB control board 5. In this embodiment, the connection section 22 of the suction pipe 2 is vertically arranged, so that the first sensing ring 31 and the second sensing ring 32 are vertically sleeved on the connection section 22 with a space therebetween. Of course, in other embodiments, the connection section 22 of the suction tube 2 may be configured to meander downward, and the distance between the first sensing ring 31 and the second sensing ring 32 refers to the distance between the connection section 22 of the suction tube 2 after being unfolded.

The working process and principle/assembly steps of the embodiments of the present invention are generally as follows:

when drinking water, the first induction ring 31 generates a first induction signal when the water flow passes through the position of the suction pipe 2 corresponding to the first induction ring 31 for the first time, the first induction signal is transmitted to the PCB control board 5, the PCB control board 5 records the drinking water starting time T1, then the second induction ring 32 generates a second induction signal when the water flow passes through the position of the suction pipe 2 corresponding to the second induction ring 32, the second induction signal is transmitted to the PCB control board 5, the PCB control board 5 records the drinking water speed calculating time T2, and the drinking water flow speed V (the drinking water flow speed can be assumed to be a constant value after test) is calculated according to the following formula because the distance between the positions of the suction pipe 2 corresponding to the first induction ring 31 and the corresponding second induction ring 32 is known:

Stopping drinking water, returning the water flow to the position corresponding to the first induction ring 31 through the suction pipe 2, generating a third induction signal by the first induction ring 31, and transmitting the third induction signal to the PCB control board 5, wherein the PCB control board 5 records the drinking water stopping time T3 (the time of the water flow falling into the first induction ring 31 from the upper end of the suction pipe 2 is extremely short and can be approximately taken as the drinking water stopping time T3), and the flow calculating chip 51 integrated by the PCB control board 5 calculates the single drinking water amount according to the following formula:

Q=V*S*(T3-T1)

wherein S is the cross-sectional area of the inner diameter of the straw 2, and the water intake of the same day is obtained by accumulating the sum of the water intake of each day.

Wherein Q is in mm, V is the drinking water flow rate in m/S, S is the cross-sectional area of the inner diameter of the suction pipe 2, and (T3-T1) is the single drinking time in S.

In this way, the cup cover 100 capable of measuring water intake can be used for generating an induction signal through induction of the corresponding position of the first induction ring 31 and the second induction ring 32 when water flows through the suction pipe 2, and transmitting the induction signal to the PCB control board 5, the flow calculation chip 51 in the PCB control board 5 can calculate the water intake on the same day through the time difference generated by the induction signal, the inner diameter cross-sectional area of the suction pipe 2, and the numerical value such as the distance between the suction pipe 2 corresponding to the first induction ring 31 and the corresponding second induction ring 32.

Therefore, the time for the water flow to reach the corresponding positions of the suction pipe 2 corresponding to the first sensing ring 31 and the second sensing ring 32 can be calculated through the voltage change signal, so that the flow calculation chip 51 of the PCB control board 5 can calculate the single water intake conveniently.

Optionally, referring to fig. 4 and 5, in the present embodiment, the suction tube 2 further includes a suction nozzle section 21 and a hose section 23, the suction nozzle section 21 is disposed through the top cover 11, and the upper end of the connection section 22 is communicated with the suction nozzle section 21 and the lower end is communicated with the hose section 23. Because the suction nozzle is of a sectional structure, the cup cover 100 capable of measuring the water intake is convenient to assemble.

In order to prevent water from penetrating into the accommodating cavity b of the cover body 1 from the joint of the suction nozzle section 21 and the connecting section 22 when a user absorbs water, and thus various electrical components are damaged. Alternatively, referring to fig. 5 and 6, in the present embodiment, an annular assembly groove c is formed at the lower end of the nozzle segment 21, a waterproof sealing ring 24 is disposed in the annular assembly groove c, and the upper end of the connecting segment 22 is inserted into the annular assembly groove c and compresses the waterproof sealing ring 24. In this way, the nozzle segment 21 and the connecting segment 22 are in waterproof sealing connection through the close fit of the annular assembly groove c and the waterproof sealing ring 24. Further, the bottom of the connection section 22 protrudes out of the bottom of the cover body seat 12 to form a plugging tubular structure, and the upper end of the hose is plugged and fixed in the plugging tubular structure of the connection section 22.

To help the user better maintain moisture intake, healthy drinking habits are fostered. Optionally, referring to fig. 7, in the present embodiment, the cup cover 100 capable of measuring water intake further includes a water drinking reminding module 6 disposed in the accommodating cavity b of the cover 1 and electrically connected to the PCB control board 5.

Optionally, referring to fig. 7, in this embodiment, the cup cover 100 capable of measuring water intake further includes a bluetooth module 8 disposed in the accommodating cavity b of the cover 1 and electrically connected to the PCB control board 5, and the PCB control board 5 sends the current day water intake calculated by the flow calculating chip 51 to the mobile terminal 300 associated therewith through the bluetooth module 8. Specifically, the mobile terminal 300 may be configured with a corresponding APP, or may be associated with the cup lid 100 with a micro signal public number, which is not particularly limited herein.

Alternatively, referring to fig. 2, in the present embodiment, the battery 4 is a rechargeable battery 4, which is connected to a charging interface 9 located on the cover 1.
