We know that with the development of modern society, environmental pollution problems are also increasing. In particular, air quality problems, such as automobile exhaust emissions, exhaust gas and smoke emissions from many metal chemical production and manufacturing sites, have seriously affected the air environment quality. Therefore, the demand for air purifiers has also increased. However, many times everyone will compare the fresh air blower and the air purifier together. In fact, the two functions are similar in themselves, and both are auxiliary equipment that can purify the air to a certain extent. However, this is only broadly speaking. In a narrow sense, there are still essential differences between the two:
The fresh air system means to filter the fresh outdoor air and send it indoors, and at the same time exhaust the dirty indoor air to the outdoors, so that a confined space can realize scientific air convection, which is equivalent to adding a breathing system to the indoor environment. The most important thing is that the fresh air system can continue to work 24 hours a day, regardless of indoor formaldehyde, benzene, toluene, xylene, radon, can all be discharged outdoors.
The air purifier, as its name implies, filters indoor pollutants (smoke, particulate matter, dust, etc.) and purifies indoor air. Purification here mainly requires the use of a filter to filter impurities and particles in the air. In the event of severe haze, the filter needs to be cleaned in time.
In general, the biggest difference between the two is the use of the principle of outer circulation and inner circulation. The fresh air blower has a ventilation function and can supplement fresh air, but it does not necessarily have a purification function, and the purifier must have a purification function. Therefore, if conditions permit, the air purification effect will be better when the two are used together.
The control panel of this household fresh air purifier air purifier developed by Sanjing, ①Function: smoke and dust removal; ②Power source: AC; ③Rated frequency: 50 (Hz); ④Control method: mechanical; ⑤Working principle: negative ion; ⑥Air purification air volume: 51-150 cubic meters/hour; ⑦Applicable area: 31 square meters (inclusive) -40 square meters (inclusive).
With the rapid development of technology, more and more smart products appear in our lives, and the automatic sensor hand sanitizer is one of them. I believe that everyone is familiar with the automatic sensor hand sanitizer, especially in some shopping malls, hotels, airports, high-speed railway stations and other places with relatively large traffic, you can basically see it as long as you go to the bathroom. This shows that it is widely used in our lives.
We know that under normal circumstances, the hand sanitizer of the traditional push-type hand sanitizer does not flow out automatically, so it needs to be touched and pressed before it flows out, which can easily cause cross-infection of germs.
The automatic induction hand sanitizer machine just solves this problem. Through the method of automatic induction drive technology, it changes the contact form of the push-type hand sanitizer machine, which effectively reduces the transmission path of germs, thereby avoiding the formation of cross-infection of germs. .
As for the automatic induction hand sanitizer, its working principle is: the signal is generated by the sensor with lens and pyroelectric tube, amplified and compared by electronic circuit, and then output switch signal to drive the DC motor to drive the deceleration mechanism to rotate, and the deceleration mechanism The connecting rod pushes the piston, and finally squeezes out the soap.
Under normal circumstances, the auto-sensing hand sanitizer has two kinds of battery life: charging power and battery. This can be selected according to the actual use scenario. For example, you can choose the battery-equipped hand sanitizer without socket holes. In addition, there are a variety of options for the dispensing method of the hand sanitizer in the automatic sensor hand sanitizer machine, such as spray, drip, and foam. However, no matter which discharge method is selected, the internal chip circuit control board needs to be set. Therefore, for electronic products, IC circuit boards are like human brains, which control the work of electronic products.
Today, LED technology has entered a mature era, and a large number of LED products have gradually penetrated into our lives. Especially the use of LED eye protection desk lamp, its principle mainly uses LED technology to have no flicker and no stroboscopic characteristics, using high-brightness, low light attenuation LED patch, when the LED eye protection desk lamp voltage DC12V is switched, it can be controlled The influence of current drive. When the atomic electrons of the general LED eye protection desk lamp act, the energy of the electrons will be reduced, and finally converted into photons to be emitted, which can ensure that the LED eye protection desk lamp has no flicker and no radiation.
With the development of social technology, there are more and more intelligent and technological electronic products, just like the traditional desk lamp that can only be used for lighting. Nowadays, touch or sensor control, Bluetooth voice dialogue, automatic dimming and timing reminders can be realized. Wait. Sanjing LED desk lamp series control panel provides users with a large degree of convenience in the process of use. First of all, the first one is about the problem of lighting. The LED eye protection desk lamp adopts polarizing film light guide technology to make the light of the LED lamp uniform. Divergence, thus effectively avoiding the problem of glare. The second is the operating method of the desk lamp. Compared with the traditional button control switch, the touch control switch can control the light with just one touch.
The LED desk lamp control panel developed by Sanjing mainly adopts touch control switch, three-level color temperature function and three-level brightness. On the basis of the traditional ordinary lighting desk lamp, the perpetual calendar function is added, including time, temperature and week display, alarm setting Wait. However, this is only a relatively basic one of the table lamp intelligent control boards developed by Sanjing. Function parameter settings such as USB charging, wireless Bluetooth/WIFI connection or automatic sensing can be customized according to actual needs.
In sports, rope skipping is one of the physical exercise items that is accepted by many people and is widely used in rope skipping sports competitions and rope skipping sports exams in families, health sports counseling centers, schools and other enterprises and institutions. Compared with other sports auxiliary equipment, the biggest advantage of skipping rope is that it is easy to store, because it is small in size, light in weight, does not occupy space, and can be used at any time. The existing skipping ropes on the market generally do not have a counting function and need to be counted manually. However, in many cases, manual counting will cause unfairness at the competition or examination site. Therefore, skipping rope closely follows the pace of the intelligent development of electronic products and becomes a skipping rope that can be automatically counted.
The realization of this electronic counting rope skipping technology includes the following elements: two handles and a rope connecting the two handles. The handle is a structure with a cavity formed by the upper cover and the lower cover interlocking with each other. One of the handles is encapsulated with a circuit board and a magnetic encoder connected to the battery, and the other is the opening of the cavity for placing the battery in the handle. The battery back cover is hinged, and the two ends of the rope pass through the connecting shaft and are fastened by fixing rope screws to achieve fixation. The magnetic encoder includes a magnet turntable, a magnetoresistive sensor and a signal processing circuit. The magnet turntable is placed in the handle and the center of the magnet turntable is provided with a waist-shaped hole. The end of the connecting shaft is waist-shaped and inserted into the waist-shaped magnet turntable. In the hole, a magnetoresistive sensor is installed inside the handle at a position corresponding to one side of the magnet turntable, and the magnetoresistive sensor is connected to the signal processing circuit in the circuit board. The surface of the upper cover is provided with a way out for the LCD screen and the buttons, and the LCD screen and the buttons are electrically connected to the circuit board.
The electronic counting rope skipping circuit board function developed by Sanjing mainly has two modes: ①forward counting mode; ②one-minute countdown counting mode; ③automatic screen rest. The forward counting is set as the default mode. The one-minute countdown mode is in the default mode. Double-click to enter this mode, and then click to start the countdown. If the time is up, an alarm will be issued automatically. Speaking of this, I believe that many people may ask questions, is this skipping count inaccurate? What I can safely tell you here is that the electronic counting skipping rope uses upgraded electronic chips, so there are generally no problems such as inaccurate counting.
