[0026] In the description of the present invention, it should be understood that the terms "first" and "second" are used in the present invention for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0027] like Figures 1 to 4As shown, an embodiment of the present invention preferably provides a water bucket with a water shortage alarm function, which includes a barrel body 1 and a capacitive sensing component 2; the barrel body 1 is provided with a first cavity for storing drinking water, and the bottom of the barrel body 1 is provided with a groove 11 recessed toward the first cavity; the capacitive sensing component 2 is arranged in the groove 11, the capacitive sensing component 2 includes a box body 21 and a first detection module, the box body 21 is provided with a second cavity, the second cavity is provided with a capacitive sensing module, a second detection module and an alarm module, the first detection module is arranged outside the second cavity, and the first detection module is electrically connected to the capacitive sensing module, the second detection module is electrically connected to the capacitive sensing module, and the capacitive sensing module is electrically connected to the alarm module; wherein the first detection module and the second detection module are used to detect the value of the capacitance in the first cavity and send a signal, the capacitive sensing module is used to receive the capacitance value signal sent by the first detection module and the second detection module, and when the capacitance value is lower than a predetermined capacitance value threshold, the capacitive sensing module controls the alarm module to alarm.

[0028] Based on the above technical features, the embodiment of the present invention is provided with a barrel body 1, wherein a first cavity for storing drinking water is provided inside the barrel body 1, which is the main part of the bucket and is used to store drinking water required by the user. A groove 11 is provided at the bottom of the barrel body 1 and is recessed toward the first cavity. The groove 11 provides an installation position for the capacitive sensing component 2, so that it can be located in the first cavity, thereby more accurately detecting water level changes. Through the provision of the capacitive sensing component 2, the capacitive sensing component 2 includes a box body 21 and a first detection module, wherein a second cavity is formed inside the box body 21 for accommodating key components such as the capacitive sensing module, the second detection module and the alarm module, and the capacitive sensing module It is the core part of the capacitive sensing component 2. It can receive the capacitance value signals from the first detection module and the second detection module, and judge whether the water level is lower than the predetermined capacitance value threshold according to these signals. The first detection module and the second detection module are respectively arranged outside and inside the second cavity. They are used to detect the capacitance value in the first cavity. When the water level changes, the capacitance value in the first cavity will also change accordingly. The two modules can capture this change and convert it into an electrical signal and send it to the capacitive sensing module. When the capacitive sensing module judges that the water level is lower than the predetermined capacitance value threshold, it will control the alarm module to send an alarm signal to remind the user that the water level in the bucket is too low and needs to be replenished in time.

[0029] As some embodiments of the present invention, Figure 3As shown, the capacitive sensing component 2 also includes an adhesive portion 23, which extends along the length direction of the box body 21, one end of the adhesive portion 23 is connected to the box body 21, and the other end is connected to the groove 11 for fixing the capacitive sensing component 2. The adhesive portion 23 is an important connecting portion between the capacitive sensing component 2 and the groove 11 of the barrel body 1. It extends along the length direction of the box body 21, one end is tightly connected to the box body 21, and the other end is firmly adhered to the groove 11. This design ensures that the capacitive sensing component 2 can be stably fixed in the groove 11 and will not loosen or fall off due to the movement or vibration of the bucket.

[0030] Furthermore, the bonding portion 23 is a sponge double-sided adhesive, which not only provides physical fixation, but also enhances the stability of the capacitive sensing component 2 in the bucket, which helps to reduce the error caused by the shaking of the component, thereby improving the accuracy of water level detection.

[0031] Furthermore, the connection surface between the groove 11 and the adhesive portion 23 is inclined to prevent the misjudgment of the liquid level staying in the horizontal direction. In conventional designs, if the connection surface is horizontal, then when the liquid level just touches the horizontal surface, a misjudgment may occur. This is because the surface tension of the liquid, bubbles, or slight fluctuations of the liquid may cause the liquid level to appear to have reached a certain horizontal position, but in fact it may not have reached it completely. This misjudgment may cause inaccurate operation or reaction of the system. By setting the connection surface between the groove 11 and the adhesive portion 23 to be inclined, this problem can be effectively solved. When the liquid level rises and contacts the inclined connection surface, due to the effect of gravity, the liquid will flow along the inclined surface, making it easier to be identified by the detection system. This design reduces the risk of misjudgment caused by slight fluctuations or bubbles in the liquid level, because even if the liquid level stays in the horizontal direction, the inclined connection surface will guide the liquid to continue flowing until it reaches a clearer detection position.

[0032] As some embodiments of the present invention, Figure 3 As shown, the capacitive sensing module is a capacitive sensing circuit board 211, and the second detection module and the alarm module are both arranged on the capacitive sensing circuit board 211. As the core of capacitive sensing, the capacitive sensing circuit board 211 can receive the capacitance value signals from the first detection module and the second detection module, and amplify, filter, convert and process these signals to obtain accurate water level information; the alarm module is an important component of the capacitive sensing component 2, which is responsible for sending an alarm signal when it detects that the water level is lower than a predetermined capacitance value threshold. After the capacitive sensing circuit board 211 processes the capacitance value signals from the first detection module and the second detection module, if it is determined that the current water level is lower than the preset value, the alarm module will immediately activate the alarm mechanism to remind the user that the water level in the bucket is too low.

[0033] As some embodiments of the present invention, Figure 4 As shown, the alarm module includes a speaker 218 and a switch 217 for controlling the speaker 218, and the capacitive sensing circuit board 211, the switch 217 and the speaker 218 are electrically connected in sequence. The speaker 218 is a key component for emitting an alarm sound. When the capacitive sensing circuit board 211 determines that the current water level is lower than a preset value, a trigger signal will be sent to the alarm module. After receiving this signal, the alarm module will immediately control the speaker 218 to emit a sound alarm; the switch 217 is a key component for controlling whether the speaker 218 emits an alarm sound. It is usually connected to the capacitive sensing circuit board 211 and receives a control signal from the capacitive sensing circuit board 211. When the capacitive sensing circuit board 211 determines that an alarm needs to be issued, a control signal will be sent to the switch 217 to close or open it, thereby controlling the power-on state of the speaker 218.

[0034] As some embodiments of the present invention, Figure 3 As shown, a battery 212 is also disposed inside the second cavity, and the battery 212 is connected to the capacitive sensing circuit board 211 to provide the electric energy required for the operation of the capacitive sensing circuit board 211. The battery 212 is the source of electric energy required for the operation of the capacitive sensing circuit board 211, and it ensures that key components such as the capacitive sensing module, the first detection module, the second detection module, and the alarm module can work continuously and stably.

[0035] As some embodiments of the present invention, Figure 3 As shown, the box body 21 includes an upper cover 213 and a battery protection cover 214. The upper cover 213 and the battery protection cover 214 are both arranged at one end of the box body 21 away from the groove 11. The battery protection cover 214 is located above the battery component 212, and the battery protection cover 214 and the upper cover 213 are detachably connected for removing the battery component 212. The battery protection cover 214 is located above the battery component 212, and the battery protection cover 214 is detachably integrated with the upper cover 213. Its main function is to provide additional protection to prevent the battery component 212 from being hit or squeezed during transportation, use or storage, thereby extending the service life of the battery.

[0036] As some embodiments of the present invention, Figure 3 As shown, the upper cover 213 is provided with a through hole 2131, which is connected to the second cavity, so as to facilitate the transmission of the alarm sound in the second cavity. As an important component of the box body 21, the upper cover 213 not only has the function of closing the opening of the box body 21, but also has the function of allowing the alarm sound in the second cavity to be transmitted. When the alarm module emits an alarm sound in the second cavity, the sound will be transmitted to the external environment through the through hole 2131, thereby alerting the user.

[0037] As some embodiments of the present invention, Figure 3 As shown, the box body 21 also includes a lower cover 215, which is arranged on a side of the box body 21 close to the groove 11. A first fixing portion 2151 and a second fixing portion 2152 are arranged on an end surface of the lower cover 215 away from the groove 11. The first fixing portion 2151 is clamped and fixed to the capacitive sensing circuit board 211, and the second fixing portion 2152 is clamped and fixed to the battery component 212. The main function of the first fixing portion 2151 is to clamp and fix with the capacitive sensing circuit board 211. This fixing method is not only simple and fast, but also can ensure the stability and reliability of the capacitive sensing circuit board 211 in the box body 21; the main function of the second fixing portion 2152 is to clamp and fix with the battery component 212. This fixing method enables the battery component 212 to be firmly installed in the box body 21 to prevent it from loosening or being damaged during transportation, use or storage.

[0038] As some embodiments of the present invention, Figure 3 As shown, the first detection module is the first antenna 22, which is arranged outside the second cavity, and the second detection module is the second antenna 216, which is arranged inside the second cavity. In the capacitive sensing component 2, the first antenna 22 is used to detect the change of the water level in the bucket. When the water level drops to a certain position, the electric field distribution around the first antenna 22 will change, thereby triggering an alarm. The main function of the second antenna 216 is to detect the first cavity inside the second cavity, and cooperate with the first antenna 22 to effectively reduce the error of detecting the water level in the bucket, so as to improve the accuracy of the capacitive sensing module in sensing the lack of water in the first cavity.

[0039] As some embodiments of the present invention, Figure 1 As shown, a handle 12 is provided on the barrel body 1 for the convenience of the user to take. The handle 12 is arranged on the outside of the barrel body 1, which is convenient for the user to touch and grasp with his hand, and it can provide the user with a more convenient and comfortable use experience, thereby enhancing the overall value and competitiveness of the product.

The first detection module and the second detection module are respectively arranged outside and inside the second cavity. They are used to detect the capacitance value in the first cavity. When the water level changes, the capacitance value in the first cavity will also change accordingly. The two modules can capture this change and convert it into an electrical signal and send it to the capacitance sensing module. When the capacitance sensing module judges that the water level is lower than the predetermined capacitance value threshold, it will control the alarm module to send an alarm signal to remind the user that the water level in the bucket is too low and needs to be replenished in time.
