The invention discloses an AR home experience method in a large scene. On the basis of combination of a natural feature identification-based three-dimensional registration method and a binocular tracking positioning and local mapping method, the camera attitude is estimated by using feature points of a real-time scene and corresponding three-dimensional points thereof under the binocular trackingpositioning and local map construction technology. According to the mode, on-site environment features shot in real time are used as recognition tracking objects, a virtual home model can still be normally positioned and tracked under the condition that no identification graph exists, the problems that an existing AR home experience application is small in use range and poor in stability are solved, and therefore the AR home experience of virtual and real fusion can be met in a wider range and more truly.

The utility model provides a powder screening device and a coffee powder screening device.The powder screening device comprises a powder screening cup body, a screw joint mounting ring, a powder receiving cup and a powder screening assembly, the powder screening cup body is in threaded connection with the screw joint mounting ring, the powder receiving cup is in threaded connection with the screw joint mounting ring, the powder screening assembly comprises a screen and a rotary knob, and the screen is provided with a clearance opening; the screwing part of the knob sequentially penetrates through the clearance opening and the screwing hole, and the knob is connected with the mounting column, so that the screen is respectively propped against the knob and the mounting column, and the outer side of the screen is also propped against the powder receiving cup. When the screen needs to be detached and replaced, the screen can be detached and replaced only by unscrewing the rotary knob to be away from the mounting column, and after the screen is mounted, the screen is fixed by screwing the rotary knob, so that the screen is convenient to detach and replace; the powder screening cup body is in threaded connection with the threaded connection installation ring, the powder receiving cup is in threaded connection with the threaded connection installation ring, the strength is high, even if the powder screening device is impacted by external force or falls off, the threaded connection state can still be kept, and the situation that coffee powder is sprayed is not prone to occurring.

The invention discloses a water purifier bacteriostasis control method, a water purifier bacteriostasis control system and a water purifier, and relates to the technical field of water purifiers, and the water purifier bacteriostasis control method comprises the following steps: obtaining an actual boiling point of water in a hot tank; when the actual boiling point does not reach the set boiling point, adjusting the actual boiling point to the set boiling point; and according to the current state of the hot tank, the difference value between the internal pressure of the hot tank and the atmospheric pressure corresponding to the set boiling point is adjusted to be within the preset range, so that the hot tank is in the positive-pressure antibacterial state. The bacteriostatic control method of the water purifier solves the problems that a traditional water purifier cannot output hot water with higher temperature under the condition of high altitude or low-pressure weather, and overnight water in a hot tank is easy to generate peculiar smell.

The invention relates to the technical field of electronic cigarettes, in particular to an electronic cigarette capable of achieving rapid oil supply through volume compression. Comprising an atomizer and an oil bottle, and the atomizer comprises a shell, a movable sealing piece, a shifting rod and an atomizing core assembly; the shell is provided with an inner cavity, a track groove, an oil guide hole and a flue; the movable sealing piece is arranged in the inner cavity and divides the inner cavity into an upper cavity and a lower cavity which are independent from each other, the rail groove is communicated with the upper cavity, the lower cavity is communicated with the flue through the oil guide hole, one end of the deflector rod is located above the movable sealing piece and abuts against the movable sealing piece, and the other end of the deflector rod is connected to the rail groove in a sliding mode and extends out of the shell; tobacco tar is supplied to the atomizing core assembly from the lower cavity through the tar guide hole; the tar bottle is provided with an arc-shaped groove, when the atomizer and the tar bottle are assembled, the shifting rod extends into the arc-shaped groove, the tar bottle is rotated to enable the arc-shaped groove to push the shifting rod to slide along the track groove, the shifting rod pushes the movable sealing piece to move along the inner cavity, the movable sealing piece compresses the volume of the lower cavity, tobacco tar in the lower cavity is squeezed to the atomizing core assembly, and the purpose of rapidly supplying the tobacco tar is achieved. And user experience is satisfied.

The invention provides a post-processing control method and device, electronic equipment and a storage medium, and relates to the technical field of engines. The post-processing control method is applied to a post-processing system comprising an engine, a catalytic reduction system and a particulate trapping catalyst, the engine, the catalytic reduction system and the particulate trapping catalyst are sequentially communicated, and the post-processing control method comprises the steps that the first exhaust temperature and the noise level of the engine are collected; and a fuel injection strategy of the engine is adjusted according to the first exhaust temperature and the noise level, so that the combustion mode and the exhaust temperature of the engine are controlled. According to the method, the problems that in the cold start stage, the exhaust temperature is usually low, and a conventional temperature rising means easily causes engine noise rising are solved, the exhaust temperature of the engine can be effectively increased on the premise that the noise is reduced as much as possible, and therefore cost, reliability and user experience can be considered on the premise that the emission standard is met.
