technical field

The utility model relates to the field of household electrical appliances, in particular to a device with dual functions of air purification and ground dust collection.

Background technique

An air purifier is a device that can clean indoor air pollution sources (inhalable particulate matter, microorganisms, and gaseous pollutants, etc.); an intelligent robot vacuum cleaner is a device that can clean ground garbage (dust, paper scraps, hair, etc.). The two devices each solve air pollution and ground garbage, and each has its own advantages. Indoor pollution has caused a health crisis. With the gradual improvement of the quality of life and the emphasis on respiratory health, air purifiers and intelligent robot vacuum cleaners will become more and more popular.

Currently, an air purifier and a robot vacuum are two separate devices with no connection. The particles suspended in the air will settle to the ground after a certain period of time. When using a vacuum cleaner, the tiny particles on the ground will return to the air, causing secondary pollution. At present, air purifiers mainly use composite high-efficiency filters for purification. When there is a lot of dust on the ground, the service life of the filters will be reduced when the air purifier is turned on.

Recently, someone has proposed a machine with both floor cleaning and air purification functions, such as the utility model patent CN205006815U published on February 3, 2016, which discloses an integrated machine for automatic cleaning and air purification.

Compared with the existing independent air purifiers and sweeping robots, the all-in-one machine represented by the above-mentioned utility model takes up less space; however, when judging whether to start the sweeping robot to clean the ground, it is based on the dust concentration in the air, which is accurate. If the temperature is not high, it is easy to cause waste of electric energy.

detailed description

The utility model will be further described in detail below in conjunction with the embodiments and accompanying drawings, but the implementation of the utility model is not limited thereto.

Example

The utility model provides an intelligent device capable of both air purification and dust suction on the ground, as shown in Figure 1, comprising a housing 1, a controller 8, a vacuum cleaner 11, and a wind wheel 3, a DC Brushless motor 4, electrostatic adsorption module 9, composite HEPA filter 2, temperature and humidity sensor 6, particle concentration sensor 7, charging pile 10 and door 5, DC brushless motor 4 is used to drive wind wheel 3, composite HEPA filter The net 2 adopts a ring structure, the electrostatic adsorption module 9 adopts a fan-shaped structure, and the electrostatic adsorption module 9 is placed at the air inlet. The schematic diagram of the system structure is shown in Figure 2. The controller 8 is connected to the brushless DC motor 4, the temperature and humidity sensor 6, and the particle concentration sensor 7 respectively. The controller communicates with the charging pile 10 and the vacuum cleaner 11 through a 2.4G wireless communication module. , to determine whether the charging pile 10 has a vacuum cleaner 11 to open the door 5 for dust collection, the controller can control the vacuum cleaner 11 for cleaning and recharging, and a chamber for accommodating the vacuum cleaner 11 is provided at the bottom of the housing 1 .

The air purifier and the intelligent robot vacuum cleaner are functionally related through the particle concentration sensor, and the realization process is shown in Figure 3. The suspended particles in the air will settle to the ground in a certain period of time. The mass of dust per unit area DM (mg/m ² ) is proportional to the concentration of dust and other particles DC (mg/m ³ ), and the settling velocity V _dc (m/h) It is directly proportional to the time t, and a correction constant C is introduced as the ground impurity that cannot be detected by the air purifier, then the dust mass per unit area is the integral of the dust particle concentration DC multiplied by the sedimentation velocity plus C to time. which is:

When obtaining the settling velocity V _dc , use a particle concentration sensor to measure the dust particle concentration per unit time in a simulated office or production workshop. After testing for a period of time, use a vacuum cleaner to clean out the dust, measure the mass, and divide it by the area to get the dust accumulation per unit area The quality DM, according to the formula (1), the sedimentation velocity V _dc is obtained by inverse calculation, and the correction constant C under different indoor environments is obtained through multiple experiments.

The controller judges the environment according to the value of the dust concentration sensor, and calculates the dust accumulation mass per unit area DM according to the settling velocity V _dc and the correction constant C. When the dust accumulation mass per unit area DM exceeds the set maximum dust accumulation mass per unit area DMmax , indicating that the floor needs to be cleaned. If the influence of air dust on the dust thickness is ignored, the dust mass per unit area of the ground within 24 hours can be obtained.

DM=C×24 (2)

At this time, the calculated DM should be slightly smaller than the maximum unit area dust mass DMmax, because some dust detected by the particle concentration sensor may be difficult to settle to the ground. In this way, a more accurate DM value can be obtained by modifying the constant C.

When the intelligent cleaning function is turned on, the logic function of the air purifier and the intelligent robot vacuum cleaner is related. When the calculated dust mass per unit area DM exceeds the maximum dust mass per unit area DMmax, it indicates that the ground needs to be cleaned. At this time, when the controller detects that the intelligent When the vacuum cleaner is at the position of the charging pile, the door of the air purifier is opened, and the smart vacuum cleaner goes out to clean according to the planned path. After cleaning the planned area or when the battery power is low, it will actively return to the charging pile to charge. When the smart vacuum cleaner returns to the charging pile, the air purifier function is turned on, and the air purifier intelligently adjusts the wind speed according to the indoor particle concentration measured by the dust concentration sensor; when the indoor air quality index reaches optimal. The air purifier works intermittently according to the particle concentration value. The smart vacuum cleaner is responsible for cleaning the dust on the ground; the air purifier purifies suspended particles, formaldehyde, odor, bacteria and viruses in the air. All-round solution to indoor purification. According to the actual situation, the air purifier and the intelligent robot vacuum cleaner can also be used alone.

The above-mentioned embodiment is a preferred implementation mode of the present utility model, but the implementation mode of the present utility model is not limited by the above-mentioned embodiment, and any other changes, modifications and substitutions made without departing from the spirit and principle of the present utility model , combination, and simplification, all should be equivalent replacement methods, and are all included in the protection scope of the present utility model.
