[0038] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0039] The specific implementation of this application will be described in detail below with reference to specific embodiments.

[0040] like Figure 1 The figure shown is an exploded view of an intelligent air-supply respirator with a detachable battery compartment provided in an embodiment of this application. The respirator includes: a housing 100, a fan 500, an air detection component, a filter component, and an electronic control component.

[0041] like Figure 2 As shown, the housing 100 has an air outlet duct 120 inside, which is used to output filtered air. The filtered air is delivered to the external protective mask or protective clothing through the air outlet duct 120.

[0042] A fan 500 is disposed on the housing 100, and the air outlet end of the fan 500 is connected to the air outlet channel 120.

[0043] like Figure 1 As shown, the filter assembly 600 is located at the air inlet end of the fan 500, and the filter assembly 600 is used to filter the air entering the fan 500.

[0044] An air detection component is disposed in the air outlet duct 120, and the air detection component is used to detect the air within the air outlet duct 120. In this embodiment, the air detection component is used to detect air parameters, specifically the concentration of PM2.5, formaldehyde, etc.

[0045] like Figure 1 As shown, the electronic control component is located in the housing 100. The electronic control component includes an electronic control board 710 and an alarm and speed control component electrically connected to the electronic control board 710. The alarm is used to sound an alarm, and the speed control component is used to adjust the rotational speed of the fan 500. In some embodiments, an air detection component is electrically connected to the electronic control board 710. The air detection component transmits detected air parameters back to the electronic control board 710. The electronic control board 710 analyzes the air parameters and determines whether they exceed the standard. When the air parameters exceed the standard, the electronic control board 710 controls the alarm to sound an alarm to remind the user. Furthermore, the electronic control board 710 adjusts the signal output by the speed control component based on the data detected by the air detection component, thereby controlling the rotational speed of the fan 500. In this way, the fan speed can be automatically controlled according to the external air quality, improving the intelligence of the respirator. It is understood that when the airflow velocity decreases, the time the air stays in the filter increases, and particulate matter has a greater chance to be captured by the filter material, improving the filtration effect and ensuring that the filtered air meets the requirements.

[0046] like Figure 1 and Figure 6 As shown, in some embodiments of this application, the housing 100 is detachably connected to a battery compartment 400. A dovetail guide rail 140 is provided on the housing 100, and the battery compartment 400 is provided with a dovetail groove 412 that slidably connects to the dovetail guide rail 140. The battery compartment 400 is connected to the housing 100 through the cooperation of the dovetail guide rail 140 and the dovetail groove 412. In this embodiment, a battery is provided inside the battery compartment 400. The battery is used to power the electrical control components and the fan 500, etc., within the housing 100. The battery compartment 400 is designed to be detachable, allowing for direct replacement and facilitating continuous operation. Furthermore, the cooperation of the dovetail guide rail 140 and the dovetail groove 412 allows for easy removal or fixation of the battery compartment 400 to the housing 100. In some embodiments, the dovetail guide rail 140 and the dovetail groove 412 are interference fits to ensure the stability of the battery compartment 400 installation.

[0047] like Figure 3 and Figure 6As shown, in some embodiments of this application, the battery compartment 400 is provided with a first elastic contact 411, and the housing 100 is provided with a second elastic contact 150 for cooperating with the first elastic contact 411. Power is transferred between the battery compartment 400 and the housing 100 through the first elastic contact 411 and the second elastic contact 150. In this embodiment, when the battery compartment 400 is fixed to the housing 100, the first elastic contact 411 and the second elastic contact 150 abut to achieve power transfer. Thus, the installation of the battery compartment 400 can be completed simply by inserting the dovetail groove 412 of the battery compartment 400 into the dovetail guide rail 140 of the housing 100 and pushing the battery compartment 400 into place, thereby achieving power transfer between the battery compartment 400 and the housing 100. When the power is insufficient, the battery compartment 400 can be directly replaced without stopping the machine to wait for charging.

[0048] In this embodiment, after being filtered by the filter assembly 600, outside air enters the fan 500 from the air inlet and, driven by the fan 500, passes through the air outlet 120 of the housing 100 and enters the external duct. As the air passes through the air outlet 120, the air detection assembly detects the air quality. If air parameters exceed the standard, an alarm is triggered to remind the user to replace the filter or leave the highly polluted area. Furthermore, the electronic control board 710 adjusts the signal output of the speed control assembly based on the data detected by the air detection assembly, thereby controlling the speed of the fan 500. This allows for automatic control of the fan speed based on the outside air quality, ensuring the quality of the filtered air and improving the intelligence of the respirator. This allows for monitoring and adjusting the filtered air quality, protecting the user's health. Additionally, the dovetail guide rail 140 and dovetail groove 412 facilitate the easy removal or fixing of the battery compartment 400 to the housing 100, enabling direct battery replacement without waiting for charging time and improving battery life.

[0049] In some embodiments of this application, the alarm is a buzzer, which emits a sharp sound to alert the user when air parameters exceed the standard. In some embodiments, the air detection component includes an organic gas sensor for detecting the concentration of volatile compounds such as toluene, formaldehyde, and benzene. When the concentration exceeds the standard, the electronic control board 710 controls the alarm to sound. In other embodiments, the air detection component may also include a sensor for detecting particulate matter concentration, specifically an electrostatic sensor.

[0050] like Figure 1 and 2As shown, in some embodiments of this application, the housing 100 has an inner cavity, and a partition plate 110 is provided in the inner cavity. The partition plate 110 divides the inner cavity into an air chamber 111 and an installation cavity 112. The fan 500 is disposed in the air chamber 111, and the electrical control assembly is disposed in the installation cavity 112. In this embodiment, the partition plate 110 separates the inner cavity of the housing 100 into the air chamber 111, so that external gas will not enter the installation cavity 112, which can effectively protect the electrical components in the installation cavity 112 and improve their service life.

[0051] like Figure 1 As shown, in some embodiments, the mounting cavity 112 is a semi-closed cavity with an opening at the top. During respirator assembly, the electronic control components can be inserted into the mounting cavity 112 through the opening at the top. The housing 100 is detachably connected to a top cover 300 for covering the opening of the mounting cavity 112. Figure 2 and Figure 5 As shown, the upper cover 300 is provided with a limiting protrusion 320, and the housing 100 is provided with a limiting groove 121. The upper cover 300 and the housing 100 are installed and fixed by the cooperation between the limiting protrusion 320 and the limiting groove 121. In some embodiments, the upper cover 300 is also provided with an air outlet 310 for connecting to an external pipe, and the air outlet 310 is connected to the air outlet channel 120 of the housing 100.

[0052] In some embodiments of this application, such as Figure 2 and Figure 4 As shown, the air cavity 111 is a semi-enclosed cavity. A front cover 200 for shielding the opening of the air cavity 111 is detachably connected to the housing 100. The front cover 200 is provided with an elastic fastener 220, and the housing 100 is provided with a fastening groove 130. The elastic fastener 220 is adapted to engage with the fastening groove 130. The front cover 200 is connected and fixed to the housing 100 through the engagement of the elastic fastener 220 and the fastening groove 130. The front cover 200 has an air inlet 230 connecting to the air cavity 111. In this embodiment, by setting the air cavity 111 as a semi-enclosed cavity, the installation of the fan 500 and the filter assembly 600 is facilitated. Furthermore, the installation is completed simply by pressing the front cover 200 onto the housing 100 using the elastic fastener 220 and the fastening groove 130, making the operation simple. In some embodiments, a spark-proof filter is installed inside the front cover 200, increasing the application environment for special operations.

[0053] In some embodiments of this application, such as Figure 4As shown, the front cover 200 has a recessed cavity near the housing 100, and the filter assembly 600 is disposed in the recessed cavity. A reinforcing rib 210 is provided within the recessed cavity, and the reinforcing rib 210 abuts against the filter assembly 600 to limit its position. In this embodiment, the filter assembly 600 is placed within the recessed cavity of the front cover 200, and the reinforcing rib 210 within the cavity limits and fixes the filter assembly 600. Thus, when the front cover 200 is fastened onto the housing 100, the installation and fixation of the filter assembly 600 can be completed without the need for screws, improving tooling efficiency.

[0054] In some embodiments, such as Figure 4 As shown, the air inlet 230 of the front cover 200 is located at the lower end, and the air inlet 230 connects to the outside and the cavity. In this embodiment, the air inlet 230 is located at the bottom, which can improve the filtration effect. It can be understood that if the air inlet 230 is located on the front of the front cover 200, after the air enters through the air inlet 230, it passes directly through the filter assembly 600 from the thickness direction, the air travel is short, and the filtration effect is poor. In this application, the air inlet 230 is located at the bottom, and the air inlet needs to travel a certain distance upward in the filter assembly 600 before exiting the filter assembly 600 and entering the fan 500, which can extend the air travel in the filter assembly 600 and improve the filtration effect.

[0055] In some embodiments of this application, a touch screen 740 is further provided on the housing 100, and the touch screen 740 is electrically connected to the electronic control board 710. In this embodiment, the user can adjust the air parameter threshold for alarm activation via the touch screen 740, making the use of the respirator more flexible. In other embodiments, the touch screen 740 can also be used to display air parameters. If an instruction manual is required, the air parameters can be PM2.5 concentration, formaldehyde concentration, etc.

[0056] In some embodiments, when the alarm sounds, the touchscreen 740 will flash red to attract the user's attention. This is understandable because in noisy environments, such as machining, construction sites, and stone cutting applications, the alarm's beeping sound may not be audible, but the flashing red light can provide supplementary alerts.

[0057] In some embodiments, such as Figure 5 As shown, the touch screen 740 is fixed to the upper cover 300 by screws, and the upper cover 300 has a perforation for displaying the touch screen 740.

[0058] In some embodiments of this application, the filter assembly 600 includes a first hollow shell 610, a second hollow shell 620, and a filter element. The first hollow shell 610 and the second hollow shell 620 are detachably connected, and when the first hollow shell 610 and the second hollow shell 620 are fastened together, they form a cavity for accommodating the filter element. In this embodiment, the detachable connection between the first hollow shell 610 and the second hollow shell 620 facilitates the replacement of the filter element inside. In some embodiments, the first hollow shell 610 and the second hollow shell 620 are connected by a snap-fit ​​structure.

[0059] In some embodiments of this application, the air detection component includes multiple sensors arranged around the air outlet duct 120. In this embodiment, using multiple sensors to detect the air within the air outlet duct reduces errors and improves accuracy.

[0060] like Figure 1 As shown, in some embodiments, there are two sensors, namely a first sensor 810 and a second sensor 820. The first sensor 810 and the second sensor 820 detect different air parameters. For example, the first sensor 810 can detect the concentration of particulate matter in the air, while the second sensor 820 can detect the concentration of formaldehyde in the air. Figure 4 As shown, in some embodiments, the peripheral wall of the air outlet duct 120 is provided with perforations, and the probes of the first sensor 810 and the second sensor 820 extend into the air outlet duct 120 through the perforations to perform detection.

[0061] like Figure 1 and Figure 3 As shown, in some embodiments, the housing is provided with a skirt 160, which surrounds the dovetail guide rail 140 and is used to limit and fix the battery compartment 400. The skirt 160 has a notch to allow the battery compartment 400 to enter. In this embodiment, the skirt 160 can limit and protect the battery compartment 400. When installing the battery compartment 400, it is only necessary to push the battery compartment 400 all the way along the dovetail guide rail 140 to complete the installation. Furthermore, the limiting of the battery compartment 400 by the skirt 160 can ensure the alignment and connection of the first elastic contact 411 and the second elastic contact 150.

[0062] In some embodiments of this application, the battery compartment 400 is provided with a charging port 430. When the battery compartment 400 is installed on the housing 100, the skirt 160 covers the charging port 430. By covering the charging port 430 with the skirt 160, the charging port 430 can be protected, preventing external damage to the charging port 430 and improving the service life of the battery compartment 400.

[0063] In some embodiments of this application, such as Figure 6 As shown, the battery compartment 400 includes an upper cover 410 and a base 420, with a space for accommodating the battery formed between the upper cover 410 and the base 420. In some embodiments, such as Figure 1 As shown, the housing 100 is also provided with a power indicator 750 for displaying the battery level. In some embodiments, such as Figure 1 As shown, the housing 100 is also equipped with a switch button 760 for turning the respirator on and off.

[0064] like Figure 1 As shown, in some embodiments of this application, the speed control component includes a PWM speed control module 730 and a speed control knob 720, which are electrically connected to the electronic control board 710. In this embodiment, the respirator has an intelligent mode and a normal mode. In normal mode, the user can actively control the signal output by the PWM speed control module 730 through the speed control knob 720, thereby controlling the speed of the fan 500. In intelligent mode, the electronic control board 710 of the respirator automatically controls the signal output by the PWM speed control module 730 based on the data detected by the air detection component, thereby controlling the speed of the fan 500. In this way, the fan speed can be automatically controlled according to the outside air quality, improving the intelligence of the respirator. In some embodiments, the average voltage across the fan 500 is changed by adjusting the duty cycle in the output signal of the PWM speed control module 730, thereby achieving speed control of the fan 500. In some embodiments, the intelligent mode and normal mode can be switched through the touch screen 740.

[0065] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
