Application of ultrasonic technology to clean dishes, can effectively save water, and can reduce the use of detergents in the case, the kitchen clean to prevent kitchen waste water containing excessive chemical contaminants, increase processing difficult. Brush covering nano-coating, can prevent bacteria breeding cracks in the brush, a self-cleaning function. It is also packed with a wireless charging base, and brush the edge of the display lights the extent you can tell plenty of electricity.

With the improvement of people's living standards, people's attention on the quality of life of pets also continue to increase, more and more people will be treated as members of the family pet. But the dogs they sometimes restrain its own nature, its sounds often interfere with people's normal life, but also to master the crisis caught complaint among potential neighbors. So people invented a product to make the dog stop barking ------ Bark Stopper. Ultrasonic Bark Stopper Methods: The ultrasonic stop barking device Form: Interference type Advantages and disadvantages: the sound of the dog's body without causing any harm, did not affect the dog's health and mood, is currently the world's safest and most humane way to stop barking. Also developed the most common way to stop barking. electric shock type Bark Stopper Methods: shock type check bark device Form: stimulate punishment type Advantages and disadvantages: After the dog subjected to electric shocks, will make it all the mental and physical harm, a great impact to the dog. Many cases show that will become very depressed, seemed uneasy, even neurotic not approach the owner to turn tail and hid in the corner after the dog subjected to electric shocks. If the vibration type of effect will obviously not such a big negative to do with.

A cat repeller is a device or substance used to discourage cats from entering an area, or to encourage them to leave if they do enter. Such deterrents are most commonly used by gardeners, in order to prevent damage to their gardens, to avoid cat feces, or to protect birds. Many retailers sell devices which exploit the discomforting effects of in-air ultrasound. These devices are usually combined with a motion sensor which is triggered by movement within the sensors range. This causes the device to emit high frequency noise which is uncomfortable to the cats, and inaudible to most humans (although they can still experience unpleasant subjective effects and, potentially, shifts in the hearing threshold). The devices are available in both battery and mains operated forms, the latter generally having a higher output, greater range and requiring less attention. Some cats are immune to ultrasonic cat deterrents, mainly the ones which are hard of hearing. There are also reports that the devices take a while to become effective, as some cats will stand their ground in a futile attempt to make the deterrent go away. Moving the device to different locations regularly and combining with another form of cat repellent may make these devices more effective. A statistical survey into customer satisfaction levels with ultrasonic deterrents concluded that 80% of owners expressed satisfaction with the results of ultrasonic deterrent devices. The Royal Society for the Protection of Birds (RSPB), has endorsed a commercial product called "CatWATCH", for which it receives 2% of the wholesale price of every device sold by the manufacturer. The RSPB tested the original CatWATCH device in a study using 63 and 96 volunteer observers in two long-running (18 and 33 weeks) blind experiments. Results from the study indicated that the device did have a moderate deterrent effect, reducing the probability of a previous cat intrusion into a garden by approximately 32% in the first experiment, but not in the longer running second experiment. Scatter guns are another form of ultrasonic device. These laser-aiming devices can be targeted at cats and activated by a trigger. They will send out an ultrasonic noise directed where aimed. Professor Timothy Leighton from the Institute of Sound and Vibration Research, has expressed concern about the recent growth in commercial products which exploit the discomforting effects of in-air ultrasound. Leighton claims that commercial products are often advertised with cited levels which cannot be critically accepted due to lack of accepted measurement standards for ultrasound in air, and little understanding of the mechanism by which they may represent a hazard.
