[0022] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] The technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0024] Indoor air pollution has become an important area that people are increasingly concerned about. People's perception of pollution usually depends on the values transmitted by sensors. If you want to understand the changes in pollutants in a polluted place, it mainly relies on the display of relevant detection data. For example, by observing the data display of 100 mg / m3 and 150 mg / m3, etc. This way of observing the detection data in real time can understand the pollution level, but it is impossible to truly feel the situation of the pollution value. Entering a polluted place can indeed truly feel the pollution situation, but if the pollution situation is very serious, it will also be harmful to human health. In practical applications, users also have the need to truly feel the pollution situation without affecting their physical health. For example, when promoting people's environmental protection work, if people can more truly feel the impact of air pollution on human breathing, it will more intuitively promote people's understanding of air pollution. However, directly allowing the human body to breathe real polluted air will be harmful to human health. Therefore, it is very important to enable people to truly experience the feeling of breathing polluted air without affecting their physical health.

[0025] Based on the above problems, the present invention provides a respirator, as Figure 1As shown, the respirator includes: a breathing mask body 1, a particulate matter generator 2 and a controller 3 disposed inside the breathing mask body 1. Among them, harmless particulate matter is stored inside the particulate matter generator 2; the controller 3 receives the pollutant concentration signal of the target polluted area, generates a control signal according to the pollutant concentration signal, and sends the control signal to the particulate matter generator 2; the particulate matter generator 2 releases harmless particulate matter according to the control signal, so that the concentration of harmless particulate matter inside the breathing mask body 1 is the same as the pollutant concentration of the target polluted area. In the embodiment of the present invention, sodium chloride particulate matter is taken as an example of harmless particulate matter for illustration. In practical applications, the harmless particulate matter can also be other particulate matters that have no impact on the human body after inhalation. The present invention is not limited thereto. In practical applications, the above-mentioned target polluted area can be a real place where air pollution occurs, such as an indoor area polluted by formaldehyde at home or a factory building where air pollution occurs, etc., or a simulated area where air pollution occurs, that is, a pollutant concentration signal of a virtual target polluted area is artificially given according to the actual feeling needs of the user. For example: simulating the current pollutant concentration signal of a certain factory building, etc. The present invention is not limited thereto.

[0026] Through the coordinated cooperation of the above-mentioned various components, the respirator provided by the embodiment of the present invention simulates the pollutant concentration of the target polluted area by using the controller to generate a corresponding control signal according to the pollutant concentration signal of the target polluted area to control the particulate matter generator to release harmless particulate matter, so that the user can truly feel the pollution situation of the target polluted area by inhaling the harmless particulate matter, enhancing the user experience.

[0027] Specifically, in one embodiment, the above-mentioned respirator further includes: a pollutant concentration detection device ( Figure 1 not shown in the figure), the pollutant concentration detection device is disposed in the target polluted area, is communicatively connected to the controller 3, and is used to detect the pollutant concentration signal of the target polluted area and send the pollutant concentration signal to the controller 3. In practical applications, the pollutant concentration detection device can be a particulate matter sensor, and the pollutant concentration signal of the target polluted area is monitored through the particulate matter sensor, and the concentration signal is converted into a corresponding electrical signal and sent to the above-mentioned controller 3. In addition, in practical applications, the pollutant concentration detection device can also be set and adjusted according to the actual experience needs of the user. For example: when the user hopes to experience the formaldehyde pollution situation of the target polluted area, the pollutant concentration detection device can be a formaldehyde sensor, etc. The present invention is not limited thereto.

[0028] Specifically, in one embodiment, the controller 3 is connected to an air purifier disposed in the target pollution area, and is configured to receive a pollutant concentration signal sent by the air purifier. If an air purifier is provided in the target pollution area, since a detection sensor for detecting the environmental pollution situation is provided inside the air purifier, the above-mentioned respirator may not be provided with a pollutant concentration detection device, but instead obtain the pollutant concentration signal by using the existing air purifier in the target pollution area. Specifically, the respirator may be wirelessly communicatively connected to the detection sensor in the air purifier to obtain the pollutant concentration signal.

[0029] Specifically, in one embodiment, a correspondence table between pollutant concentration and the release time of the particulate matter generator 2 is pre-stored inside the controller 3, and the controller 3 generates a control signal according to the pollutant concentration signal and the correspondence table. In practical applications, since the internal volume of the breathing mask body 1 of the respirator is fixed, therefore, the relationship between the concentration of harmless particulate matter inside the breathing mask body 1 and the release duration of the particulate matter generator 2 can be obtained by the internal air volume and the inherent harmless particulate matter release rate of the particulate matter generator 2, that is, the correspondence table between pollutant concentration and particulate matter release time can be obtained. Thus, the controller 3 can use this correspondence table to directly generate a control signal corresponding to the opening duration of the particulate matter generator 2.

[0030] In addition, in practical applications, the correspondence table can also be divided into multiple levels according to the concentration range, each level corresponding to a release time of the particulate matter generator 2, and then multiple comparators are built into the controller 3. By comparing the preset concentration value with the pollutant concentration value in the target pollution area by the multiple comparators, a control signal for the particulate matter generator 2 is generated. The specific circuit structure setting method of the comparator can be implemented by using the relevant principles of the comparator in the prior art, and will not be elaborated here.

[0031] Specifically, in one embodiment, as Figure 1 shown, the above-mentioned respirator further includes: an air inlet cavity 4 connected to the breathing mask body 1, configured to convey external air to the inside of the breathing mask body 1. An air outlet cavity 5 connected to the breathing mask body 1, configured to discharge the gas exhaled by the human body inside the breathing mask body 1 from the breathing mask body 1. It should be noted that the above-mentioned air inlet cavity 4 and air outlet cavity 5 can be set with reference to the settings of breathing masks and respirators in the prior art, and will not be elaborated here. A sealing rubber ( Figure 1 not shown in the figure) is provided at the edge of the breathing mask body 1 to enhance the sealing performance of the breathing mask body 1.

[0032] Specifically, in one embodiment, the above-mentioned respirator further includes: a starting device disposed outside the breathing mask body 1 ( Figure 1(not shown in the figure), the starting device is connected to the power supply terminal of the controller 3. When the user turns on the starting device, the controller 3 is powered on to receive the pollutant concentration signal of the target pollution area. In the embodiment of the present invention, the starting device is taken as an example of a push-button switch for illustration. In actual applications, the starting device can also be a rotary switch, etc., as long as it can achieve the function of turning on the power supply of the controller 3. The present invention is not limited thereto.

[0033] Next, the working principle and working process of the respirator provided by the present invention will be described in detail with specific application examples.

[0034] The present invention aims to provide a solution for remotely sensing pollution conditions. Taking the above-mentioned target pollution area as the indoor area and the controller 3 being communicatively connected to the sensor built in the indoor air purifier as an example,

[0035] Application scenario 1: The specific working process is as Figure 2 shown. When the sensor in the indoor air purifier senses indoor pollution, the sensor will generate an electrical signal and send the signal to the controller 3 in the respirator. After receiving the signal, the controller 3 in the respirator controls the start of the particulate generator 2 in the respirator to generate harmless sea salt particles (sodium chloride particles) with a corresponding concentration, enabling the user to remotely sense the indoor pollution situation.

[0036] Application scenario 2: Taking the respirator as shown in Figure 1 as an example, when the user needs to know the indoor pollutant concentration, the user wears the above-mentioned respirator and presses the start button. During the working process, the indoor particulate sensor detects the corresponding concentration and transmits the data signal to the internal controller 3 of the respirator. After receiving the corresponding data signal, the controller 3 controls the particulate generator 2 to start for a fixed time. There are a certain number of NaCl particles inside the particulate generator 2. After the particulate generator 2 starts, it releases harmless particles with a corresponding concentration. The user can understand the indoor pollutant concentration situation in real time by inhaling the particles.

[0037] Through the collaborative cooperation of the above-mentioned various components, the respirator provided by the embodiment of the present invention simulates the pollutant concentration of the target pollution area by using the controller to generate a corresponding control signal according to the pollutant concentration signal of the target pollution area to control the particulate generator to release harmless particles, enabling the user to truly feel the pollution situation of the target pollution area by inhaling the harmless particles, thereby enhancing the user experience.

[0038] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
