Or return the remaining water in the connecting water pipe to the water flow adjustment device in the drinking water bottle. The bottom of the inner tank is provided with a water outlet, and the corresponding place of the water outlet is provided with a control valve for controlling the water outlet. There is a drinking cup below. The vehicle-mounted drinking water device can return the remaining water in the water pipe to the drinking water bottle, without accumulated water, and the drinking water is convenient and hygienic. In addition, the structure is miniaturized and is suitable for vehicle-mounted use.

A waterincoming pipe matched with the water incoming valve is fixed at the upper end of the base, and a water pipe connected with a water source is arranged below the water incoming pipe through a first ball valve and a second ball valve; a triggering inclined rod matched with the kettle body is slidably connected on the base, a resetting inclined rod capable of pushing the triggering inclined rod through a bevel is slidably connected in the base, one end of the resetting inclined rod is connected with the base through a spring while the other end of the same is in rotary clamping connection with asliding gear meshed with a linkage gear, the sliding gear is connected with the second ball valve through a concentric connection shaft, the sliding gear can slide on the connection shaft while driving the same to rotate, and the connection shaft is in transmission connection with the second ball valve through a ratchet mechanism. The convenient intelligent water diversion heating kettle is simpleto operate, and volume of water in the kettle can be controlled accurately.

The invention discloses an automatic milk preparation machine. The automatic milk preparation machine comprises: a casing; a quantitative feeding mechanism, wherein the quantitative feeding mechanism is provided with a milk powder silo and a reclaimer communicated with the milk powder silo; a water storage mechanism, The water storage mechanism is connected in communication with the quantitative feeding mechanism, and a shaking mechanism. In this way, since the volume of the reclaimer is fixed, the user can select an appropriate amount of milk powder according to their actual needs. In addition, the water storage mechanism is connected to the quantitative feeding mechanism in communication, and the water storage mechanism will automatically confirm the required water amount according to the amount of milk powder actually put in by the reclaimer, so that the water amount when brewing milk powder can be accurately controlled. By setting the shaking mechanism, the milk in the milk bottle can be shaken, and the milk preparation can be completed automatically without manual operation.

The invention discloses an intelligent water diversion kettle for making tea and boiling water, which comprises a kettle body with a water inlet valve at the bottom and a base matched with the kettle body, and a water inlet pipe matched with the water inlet valve is fixed on the upper end of the base. Below the water inlet pipe, there is a water pipe connected to the water source through the first ball valve and the second ball valve; the base is slidably connected with a trigger inclined rod that cooperates with the pot body, and the base is slidably connected with a trigger that can be pushed through an inclined plane. The reset inclined rod for triggering the inclined rod is described. One end of the reset inclined rod is connected to the base through a spring, and the other end is rotated and clamped with a sliding gear that can mesh with the interlocking gear. The sliding gear is connected through a concentric connecting shaft Connected with the second ball valve, the sliding gear can drive the connecting shaft to rotate while sliding on the connecting shaft, and the connecting shaft is in drive connection with the second ball valve through a ratchet mechanism. The invention has simple operation and can accurately control the water volume in the kettle.

The embodiment of the invention discloses an inner container parameter control device for an electric water heater. The electric water heater comprises an inner container, a heating assembly and a water inflow and outflow control unit, and inner container parameters include the inner container pressure value. The device comprises a microcontroller and a pressure control unit arranged outside the inner container. The microcontroller controls the water inflow and outflow control unit, and accordingly the electric water heater can work in different work modes. The work modes include the whole container heating mode, the half container heating mode and the variable volume mode. The pressure control unit detects the pressure value in the inner container in real time when the electric water heater is in different work modes, and the pressure value is fed back to the microcontroller in real time. The microcontroller controls the pressure control unit to act according to the pressure value, accordingly, the pressure difference between the inner container and the outside can be balanced or the pressure value needed for water inflow and outflow in the current work mode is achieved. Through the embodiment scheme, the electric water heater inner container pressure parameters are reliably and automatically detected, and reliable control over the electric water heater is achieved.

The invention discloses a method of synthesizing a molecular sieve by using a solid phase. In the method, ammonium fluoride is used as a mineralizing agent and a brominized organic template is used as a guiding agent; and the method comprises the following steps: mixing a certain amount of water with anhydrous sodium metasilicate and recrystallizing to form crystal water-containing sodium metasilicate; then, mixing and grinding the certain amount of crystal water-containing sodium metasilicate, white carbon black, the brominized organic template, ammonium fluoride and / or aluminum nitrate together till mixing uniformly, then putting the ground mixture into a glass tube and sealing with flame; and crystallizing the sealed glass tube in an oven at 180 DEG for 4 weeks, washing the reaction products and drying the reaction products in an oven with the temperature of 60 DEG C till the reaction products are completely dried. By using ammonium fluoride as the mineralizing agent, an ITO (Indium tin oxide)-13 molecular sieve which cannot be obtained in an alkaline synthesis route and an F-ZSM (Zeolite Socony Mobil)-5 zeolite molecular sieve are obtained, and good degree of crystallinity and purity are kept. The reactant cost is lowered, the energy consumption is reduced and the product purity is high.
