Description

Technical Field

[0001] The utility model relates to the field of bathroom shower water channel components, in particular to a digital display device used in a bathroom shower. Background Art

[0002] At present, the common faucet valve cores on the market only have the function of water distribution or water switching. As people's requirements for kitchen and bathroom products become higher and higher, they pay more and more attention to the diversity of their functions. Therefore, LED light display faucets, temperature display faucets, etc. have appeared in faucet products. These functions all require electricity to achieve. In the water circuit, the external power supply not only has complex circuits, but also has low safety. It is easy to bring danger to users due to moisture, leakage and other problems. Therefore, its power supply problem has become the main factor restricting development and practical application. In view of this, the Chinese utility model patent with patent number: CN204852465U discloses a hydroelectric valve core, including a valve core seat, a valve core group and a hydroelectric power generation group. The valve core seat is provided with a water outlet channel and at least one water inlet channel. The valve core group includes a moving valve plate and a static valve plate. The moving valve plate is provided with at least one water through hole. The static valve plate and the valve The core seat is fixed and has a water inlet hole and a water outlet hole corresponding to the water inlet channel and the water outlet channel. The movable valve plate moves relative to the static valve plate and realizes the opening and closing and water distribution of the valve core through the cooperation of the water hole and the communicating area of ​​the water inlet hole and the water outlet hole. The hydroelectric power generation group includes an impeller, which is arranged in the water outlet channel and rotates under the drive of the outlet water flow. The hydroelectric power generation valve core realizes the opening and closing and water distribution through the action of the movable and static valve plates of the valve core group and the water inlet and outlet channels of the valve core seat. The hydroelectric power generation group is arranged on the water outlet channel, and its impeller rotates under the drive of the outlet water flow to realize power generation.

[0003] Although this structure uses an impeller that rotates under the drive of water flow to generate electricity, thereby powering components to realize the digital display function of the faucet (i.e., LED light display of the faucet, temperature display), however, since its impeller is installed in the water outlet channel, and due to the different water quality in different regions, impurities are easily accumulated in the water outlet channel in some areas with poor water quality, and the impeller must have stable rotation for power generation. When too many impurities accumulate in the water outlet channel, the rotation of the impeller becomes weak, which can easily lead to unstable power generation, making the digital display function unable to work stably, resulting in a short service life. It is necessary to improve this. Summary of the invention

[0004] The technical problem to be solved by the present invention is to address the deficiencies of the above-mentioned prior art.

[0005] The invention provides a digital display device for bathroom showers which can replace the hydraulic generator, save resources and work stably.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a digital display device for a bathroom shower, comprising a shell and a digital display screen, characterized in that it also includes a power supply electrically connected to the digital display screen, a first cavity is provided at one end of the shell, a temperature sensor and a switch sensor electrically connected to the digital display screen are provided in the first cavity, the first cavity is sealed after the temperature sensor and the switch sensor are installed, at least one water inlet is provided at the other end of the shell, an impeller accommodating cavity is provided in the middle of the shell, an impeller is provided in the impeller accommodating cavity, at least one water outlet is opened in the circumferential direction of the impeller accommodating cavity of the shell, a water outlet channel is formed between the water inlet and the water outlet, an impeller shaft which can drive the impeller to rotate is provided in the middle of the impeller, one end of the temperature sensor penetrates into the impeller accommodating cavity, one end of the impeller shaft penetrates into the first cavity and is connected to a trigger member which can control the on and off of the switch sensor.

[0007] In the prior art, the circuit board of the digital display screen has a switch circuit, a power drive circuit, and a temperature display circuit, which is common knowledge in the art and will not be elaborated here.

[0008] The working method of the utility model is as follows: the shell is installed in the water path of the bathroom shower, waterproof glue is injected into the first cavity for sealing, one end of the shell is provided with a water inlet facing the front end of the water flow of the water path, and the digital display screen and the power supply are installed on the mounting seat of the shower. When the shower is turned on, the water flows into the shell through the water inlet and flows out of the shell through the water outlet. In this process, the water flow will drive the impeller installed in the impeller accommodating cavity and cause the impeller to rotate along the impeller shaft. When the impeller rotates, the trigger member connected to the other end of the impeller shaft controls the switch sensor to be connected under the drive of the impeller shaft. After the connection, the current water flow temperature and the continuous working time of the switch sensor are displayed on the digital display screen. This time can be regarded as the water flow time of the shower, and can also be called the working time.

[0009] By adopting the above technical scheme, in the technical scheme of the utility model, the impeller rotates only to trigger the switch sensor and is not used for power generation. Therefore, no matter the hydraulic force or water quality of the water flow flowing from the water inlet through the water outlet to drive the impeller to rotate, as long as it can drive the impeller to rotate, the impeller shaft can drive the trigger member to trigger the switch sensor, thereby realizing the power supply of the entire component, greatly improving the service life of the digital display device, and the shell can be directly made to be consistent with the appearance of the hydraulic generator in the prior art, which can replace the hydraulic generator, save resources, and there is no need to re-open the mold to make the shell.

[0010] The above-mentioned digital display device for bathroom shower can be further configured as follows: the impeller is arranged in the impeller accommodating cavity and is located between the water inlet and the water outlet.

[0011] By adopting the above technical solution, in order to ensure that the water flow in the water channel can cause the impeller to rotate and drive the impeller shaft to rotate, the impeller is arranged between the water inlet and the water outlet. After the water flows into the impeller accommodating cavity, it will first drive the impeller to rotate, and then go out from the water outlet, thereby improving the working stability of the device.

[0012] The above-mentioned digital display device for bathroom shower can be further configured as follows: a box body with an opening toward one end of the impeller accommodating cavity is provided in the first cavity, the trigger member is located in the box body, and the box body is provided with a avoidance groove with a give-way design at the corresponding positions of the temperature sensor and the switch sensor, and the first cavity is sealed by waterproof glue after the temperature sensor and the switch sensor are installed.

[0013] By adopting the above technical solution, the trigger is set in the box body by setting a box body in the first cavity, and the box body is designed with an avoidance groove at the position of the temperature sensor and the switch sensor. On the one hand, it is convenient to install the temperature sensor and the switch sensor, and on the other hand, it also plays a role in the installation and positioning of the temperature sensor and the switch sensor. After the temperature sensor and the switch sensor are installed, they are sealed with waterproof glue. After sealing, it is ensured that no water enters the first cavity. Although one end of the temperature sensor extends into the impeller accommodating cavity, after the waterproof glue is injected into the first cavity, water still cannot enter the first cavity from the installation position of the temperature sensor, thereby ensuring the sealing performance.

[0014] The above-mentioned digital display device for bathroom shower can be further configured as follows: the switch sensor includes a switch circuit board and a Hall sensor installed on the switch circuit board, the switch circuit board is electrically connected to the power supply through wires, and the trigger member is a magnet.

[0015] By adopting the above technical solution, the switch sensor is set as a switch circuit board and a Hall sensor installed on the switch circuit board. Of course, the switch circuit board is just a name, and it can be any circuit board that can install a Hall sensor and transmit the Hall sensor signal. When the impeller rotates under the flushing of the water flow, the magnet installed at one end of the impeller shaft in the first cavity will rotate accordingly. When rotating, the Hall sensor will generate a pulse signal. The digital display screen will turn on the digital display when it detects the pulse signal to display the temperature and working time. Of course, other displayable data can also be set on the digital display screen. Technical personnel in this field are motivated to display different data after adaptive settings, which will not be elaborated here.

[0016] The above-mentioned digital display device for bathroom shower can be further configured as follows: a mounting hole is opened at one end of the impeller shaft located in the box body, and the magnet is arranged in the mounting hole.

[0017] With the above technical solution, since the impeller shaft is made of steel, the magnet can be adsorbed on the impeller shaft and rotate with the impeller shaft. Of course, in order to ensure stability, it is a better choice to open a mounting hole on the impeller shaft and install the magnet in the mounting hole.

[0018] The above-mentioned digital display device for bathroom shower can be further configured as follows: the digital display screen is connected to a charging port.

[0019] With the above technical solution, the power supply is generally configured as a rechargeable battery, and the MCU of the digital display screen can charge the power supply through the charging port to replenish the power of the power supply.
