Detailed Description

Exemplary embodiments that embody features and advantages of this disclosure are described in detail below in the detailed description. It will be understood that the present disclosure is capable of various modifications without departing from the scope of the disclosure, and that the description and drawings are to be regarded as illustrative in nature, and not as restrictive.

Referring to fig. 1A to 2B, a gas purifying apparatus is provided, which includes a gas purifier 1 and a gas monitor 2. The gas purifier 1 includes a purifier body 11, a filter 12, a blower 13 and a driving control module 14. The purifier body 11 is provided with at least one air inlet 111 and one air outlet 112 at the outside thereof, and an air guiding channel 113 inside thereof, which is communicated between the air inlet 111 and the air outlet 112. And the filter 12 is assembled between the air inlet 111 and the air guide flow passage 113 to allow the gas to be purified to pass through and enter the air guide flow passage 113. The air guide 13 is disposed between the air outlet 112 and the air guide channel 113 to guide the air in the air guide channel 113 to be discharged from the air outlet 112. Therefore, when the air guiding machine 13 is driven, the air guiding machine 13 can draw the air in the air guiding flow channel 113, so that the external air enters from the air inlet 111, penetrates through the filter screen 12 to be purified, then enters into the air guiding flow channel 113, and is discharged from the air outlet 112, so that the user can breathe clean air. Also, an embedding groove 114 is provided outside the purifier body 11, in which the gas monitor 2 is assembled for positioning use, or detached from the embedding groove 114 for separate and independent use. The driving control module 14 is disposed inside the main body 11, and a connection port 115 is disposed in the embedding slot 114 for electrically connecting with the driving control module 14. The gas monitor 2 is assembled and positioned in the embedding groove 114, and can be electrically connected with the driving control module 14 through the electrical connection with the connection port 115 to provide power for use. In the present embodiment, the filter 12 may be an electrostatic filter, an activated carbon filter, or a high efficiency filter (HEPA).

Referring to fig. 2A to 2B and fig. 11, the driving control module 14 includes a power supply battery 141, a communication element 142 and a microprocessor 143. The power supply battery 141 can be connected to a power source to store electric energy, so as to output the electric energy to the microprocessor 143 and the air guide 13. The power supply battery 141 may be connected to the power source by charging and storing electric energy by wired transmission or wireless transmission. The communication component 142 transmits and receives the monitoring data information of the gas monitoring machine 2 through wireless communication, or receives the transmission signal of the external connection device 50, and then sends the transmission signal to the microprocessor 143 to be converted into a control signal, so as to control the start of the air guide machine 13 and purify the gas by the gas purifier 1.

Referring to fig. 3A to 6, the gas monitor 2 includes a monitor body 21, a gas detection module 22, a particle monitoring module 23, a monitoring power supply 24 and a monitoring driving control module 25. The monitoring device body 21 has a chamber 211 therein, and a first inlet 212, a second inlet 213 and a monitoring outlet 214 are disposed outside and respectively connected to the chamber 211.

Referring to fig. 3E and fig. 4A to 4E, the gas detection module 22 includes a compartment body 221, a carrier plate 222, a gas sensor 223 and a gas actuator 224. The compartment body 221 is disposed below the first inlet 212 of the monitoring device body 21, and a partition 221a divides the interior thereof into a first gas compartment 221b and a second gas compartment 221 c. The spacer 221a has a notch 221d for communicating the first gas compartment 221b and the second gas compartment 221c with each other. In addition, the first gas compartment 221b has an opening 221e, the second gas compartment 221c has a gas outlet 221f, and the bottom of the compartment body 221 has a receiving groove 221 g. The receiving groove 221g is used for the carrier 222 to penetrate and be positioned therein, so as to close the bottom of the compartment body 221. The carrier 222 is provided with a vent 222a, and the carrier 222 is packaged and electrically connected with a gas sensor 223, such that when the carrier 222 is assembled under the compartment body 221, the vent 222a corresponds to the gas outlet hole 221f of the gas second compartment 221c, and the gas sensor 223 extends into the opening 221e of the gas first compartment 221b and is disposed in the gas first compartment 221b to detect the gas in the gas first compartment 221 b. The gas actuator 224 is disposed in the second gas compartment 221c and isolated from the gas sensor 223 disposed in the first gas compartment 221b, so that the heat generated by the gas actuator 224 during operation can be isolated by the spacer 221a without affecting the detection result of the gas sensor 223. The gas actuator 224 closes the bottom of the gas second compartment 221c and is controlled to actuate to generate a guiding gas flow, so that the guiding gas flow is discharged out of the compartment body 221 through the gas outlet 221f of the gas second compartment 221c and then out of the gas detection module 22 through the gas vent 222a of the carrier plate 222. The carrier 222 may be a circuit board, and has a connector 222b, the connector 222b is used for a circuit board (not shown) to penetrate and connect, so that the monitor driving control module 25 (as shown in fig. 5) and the carrier 222 can be electrically connected and signal-connected.

With reference to fig. 4A, 4D and 4E, for convenience of describing the gas flowing direction in the gas detecting module 22, the monitor body 21 is transparently processed in the illustration. When the gas detection module 22 is disposed in the cavity 211 of the monitoring body 21, the first gas inlet 212 of the monitoring body 21 corresponds to the first gas compartment 221b of the compartment body 221. In the present embodiment, the first gas inlet 212 of the monitoring body 21 and the gas sensor 223 located in the first gas compartment 221b do not directly correspond to each other, i.e. the first gas inlet 212 is not directly located above the gas sensor 223, and the two are offset from each other. Thus, by the control operation of the gas actuator 224, the gas second compartment 221c starts to form a negative pressure, and starts to draw the external gas outside the monitoring device body 21, and the external gas is introduced into the gas first compartment 221b, so that the gas sensor 223 in the gas first compartment 221b starts to monitor the gas flowing through the surface thereof, and the quality of the gas outside the monitoring device body 21 is detected. When the gas actuator 224 is continuously activated, the monitored gas is introduced into the gas second compartment 221c through the notch 221d of the partition 221a, and finally discharged out of the compartment body 221 through the gas outlet hole 221f and the gas vent 222a of the carrier plate 222, so as to form a unidirectional gas guiding monitor (as indicated by the direction of the gas flow path a in fig. 4E).

The gas sensor 223 may be at least one of an oxygen sensor, a carbon monoxide sensor, a carbon dioxide sensor, a temperature sensor, an ozone sensor, and a volatile organic compound sensor, or a combination thereof; alternatively, the gas sensor 223 may be at least one of a bacterial sensor, a viral sensor, or a microbial sensor, or a combination thereof.

Referring to fig. 7A to 7B, the gas actuator 224 is a micro pump 30, and the micro pump 30 is formed by sequentially stacking a flow inlet plate 301, a resonant plate 302, a piezoelectric actuator 303, a first insulating plate 304, a conductive plate 305 and a second insulating plate 306. The flow inlet plate 301 has at least one flow inlet hole 301a, at least one bus slot 301b and a bus chamber 301 c. The inlet hole 301a is supplied with the introduced gas, the inlet hole 301a correspondingly penetrates through the bus groove 301b, and the bus groove 301b is converged into the converging chamber 301c, so that the introduced gas from the inlet hole 301a is converged into the converging chamber 301 c. In the present embodiment, the number of the inflow holes 301a is the same as that of the bus bar groove 301b, and the number of the inflow holes 301a is 4, respectively, but not limited thereto. The 4 inflow holes 301a penetrate the 4 bus grooves 301b, respectively, and the 4 bus grooves 301b converge to the bus chamber 301 c.

Referring to fig. 7A, 7B and 8A, the resonator plate 302 is attached to the flow inlet plate 301 by a bonding method, and the resonator plate 302 has a hollow hole 302a, a movable portion 302B and a fixed portion 302 c. The hollow hole 302a is located at the center of the resonator plate 302 and corresponds to the confluence chamber 301c of the inflow plate 301, the movable portion 302b is disposed at a region around the hollow hole 302a and opposite to the confluence chamber 301c, and the fixed portion 302c is disposed at an outer peripheral portion of the resonator plate 302 and is attached to the inflow plate 301.

As shown in fig. 7A, 7B and 8A, the piezoelectric actuator 303 includes a suspension plate 303a, a frame 303B, at least one support 303c, a piezoelectric element 303d, at least one gap 303e and a protrusion 303 f. The suspension plate 303a is in a square shape, and the suspension plate 303a is square, so compared with the design of a circular suspension plate, the structure of the square suspension plate 303a obviously has the advantage of power saving, because of the capacitive load operated under the resonant frequency, the consumed power of the square suspension plate 303a is increased along with the rise of the frequency, and because the resonant frequency of the square suspension plate 303a is obviously lower than that of the circular suspension plate, the relative consumed power is also obviously lower, namely the square suspension plate 303a adopted in the scheme has the benefit of power saving; the outer frame 303b is disposed around the outer side of the suspension plate 303 a; at least one bracket 303c is connected between the suspension plate 303a and the outer frame 303b to provide a supporting force for elastically supporting the suspension plate 303 a; and a piezoelectric element 303d having a side length less than or equal to a side length of the suspension plate 303a, and the piezoelectric element 303d is attached to a surface of the suspension plate 303a for being applied with a voltage to drive the suspension plate 303a to vibrate in a bending manner; at least one gap 303e is formed between the suspension plate 303a, the outer frame 303b and the bracket 303c for air to pass through; the protrusion 303f is disposed on the other surface of the suspension plate 303a opposite to the surface to which the piezoelectric element 303d is attached, and in this embodiment, the protrusion 303f may be a protrusion integrally formed on the other surface of the suspension plate 303a opposite to the surface to which the piezoelectric element 303d is attached by performing an etching process.

Referring to fig. 7A, fig. 7B and fig. 8A, the flow inlet plate 301, the resonator plate 302, the piezoelectric actuator 303, the first insulating plate 304, the conductive plate 305 and the second insulating plate 306 are sequentially stacked and combined, wherein a cavity space 307 is required to be formed between the floating plate 303a and the resonator plate 302. The chamber space 307 may be formed by filling a material between the resonator plate 302 and the outer frame 303b of the piezoelectric actuator 303, such as: the conductive paste, but not limited thereto, allows the cavity space 307 to be formed between the resonator plate 302 and the suspension plate 303a with a certain depth, so as to guide the gas to flow more rapidly, and reduce the contact interference between the suspension plate 303a and the resonator plate 302, so that the noise generation can be reduced. Of course, in the embodiment, the height of the outer frame 303b of the high voltage electric actuator 303 may be added to reduce the thickness of the conductive adhesive filled between the resonator plate 302 and the outer frame 303b of the piezoelectric actuator 303, so as to prevent the conductive adhesive from expanding with heat and contracting with cold with the hot pressing temperature and the cooling temperature to affect the actual distance between the cavity space 307 after molding, and reduce the indirect effect of the hot pressing temperature and the cooling temperature of the conductive adhesive on the assembly of the whole structure of the micro pump 30, but not limited thereto. In addition, the chamber space 307 will affect the delivery performance of the micro-pump 30, so it is important to maintain a constant chamber space 307 to provide a stable delivery efficiency for the micro-pump 30.

Thus, as shown in fig. 8B, in other embodiments of the piezoelectric actuator 303, the suspension plate 303a may be formed by stamping to extend outward by a distance adjustable by at least one support 303c formed between the suspension plate 303a and the outer frame 303B, such that the surface of the protrusion 303f on the suspension plate 303a and the surface of the outer frame 303B are both non-coplanar, and a small amount of filling material is applied to the mating surface of the outer frame 303B, for example: the conductive adhesive is used for adhering the piezoelectric actuator 303 to the fixing portion 302c of the resonator plate 302 in a hot pressing manner, so that the piezoelectric actuator 303 can be assembled and combined with the resonator plate 302, and thus, the structural improvement that the suspension plate 303a of the piezoelectric actuator 303 is formed into a cavity space 307 by stamping is directly realized, and the required cavity space 307 can be completed by adjusting the stamping forming distance of the suspension plate 303a of the piezoelectric actuator 303, thereby effectively simplifying the structural design for adjusting the cavity space 307, simplifying the manufacturing process, shortening the manufacturing time and the like. In addition, the first insulating sheet 304, the conductive sheet 305 and the second insulating sheet 306 are frame-shaped thin sheets, and are sequentially stacked on the piezoelectric actuator 303 to form the overall structure of the micro-pump 30.

To understand the output operation of the micro pump 30 for gas transmission, please refer to fig. 8C to 8E. Referring to fig. 8C, after the driving voltage is applied to the piezoelectric element 303d of the piezoelectric actuator 303, the piezoelectric element 303d deforms to drive the suspension plate 303a to move downward, and at this time, the volume of the chamber space 307 is increased, so that a negative pressure is formed in the chamber space 307, and the gas in the confluence chamber 301C is drawn into the chamber space 307, and the resonance plate 302 is simultaneously moved downward under the influence of the resonance principle, so that the volume of the confluence chamber 301C is increased, and the gas in the confluence chamber 301C is also in a negative pressure state due to the fact that the gas in the confluence chamber 301C enters the chamber space 307, and further the gas is drawn into the confluence chamber 301C through the inflow hole 301a and the bus groove 301 b; referring to fig. 8D, the piezoelectric element 303D drives the suspension plate 303a to move upward to compress the chamber space 307, and similarly, the resonator plate 302 moves upward due to resonance with the suspension plate 303a to force the gas in the chamber space 307 to be pushed and pushed synchronously downward through the gap 303e to be transmitted downward, so as to achieve the effect of transmitting the gas; finally, referring to fig. 8E, when the suspension plate 303a returns to the original position, the resonator plate 302 still moves downward due to inertia, and the resonator plate 302 moves the gas in the compression chamber space 307 toward the gap 303E and increases the volume in the collecting chamber 301c, so that the gas can continuously pass through the inflow hole 301a and the collecting groove 301b to be collected in the collecting chamber 301 c. By repeating the operation steps of the micro pump 30 shown in fig. 8C to 8E for providing gas transmission, the micro pump 30 can make the gas continuously enter the flow channel formed by the flow inlet plate 301 and the resonator plate 302 from the flow inlet hole 301a to generate a pressure gradient, and then transmit the gas downwards through the gap 303E, so that the gas flows at a high speed, thereby achieving the operation of outputting the gas transmitted by the micro pump 30.

Referring to fig. 8A, the inlet plate 301, the resonator plate 302, the piezoelectric actuator 303, the first insulating plate 304, the conductive plate 305, and the second insulating plate 306 of the micro-pump 30 can be processed by micro-electromechanical surface micromachining to reduce the volume of the micro-pump 30, thereby forming a micro-pump of the mems.

Of course, the gas actuator 224 may be configured as the micro-pump 30, or may be configured and operated as a blower box micro-pump 40 to deliver gas. Referring to fig. 9 and 10A to 10C, the blower box micropump 40 includes a gas injection hole piece 401, a cavity frame 402, an actuating body 403, an insulating frame 404 and a conductive frame 405 stacked in sequence. The air hole plate 401 includes a plurality of connecting members 401a, a suspension plate 401b and a hollow hole 401c, the suspension plate 401b can be bent and vibrated, and the connecting members 401a are adjacent to the periphery of the suspension plate 401 b. In this embodiment, the number of the connecting members 401a is 4, and the connecting members are respectively adjacent to the 4 corners of the floating plate 401b, but not limited thereto. A hollow hole 401c is formed at the center of the floating plate 401 b. The chamber frame 402 is carried to be superposed on the suspension plate 401 b. The actuating body 403 is stacked on the chamber frame 402, and comprises a piezoelectric carrier plate 403a, an adjusting resonator plate 403b, and a piezoelectric plate 403c, wherein the piezoelectric carrier plate 403a is stacked on the chamber frame 402, the adjusting resonator plate 403b is stacked on the piezoelectric carrier plate 403a, and the piezoelectric plate 403c is stacked on the adjusting resonator plate 403b for generating deformation after being applied with voltage, so as to drive the piezoelectric carrier plate 403a and the adjusting resonator plate 403b to perform reciprocating bending vibration. The insulating frame 404 is supported on the piezoelectric carrier plate 403a stacked on the actuating body 403, and the conductive frame 405 is supported on the insulating frame 404, wherein a resonant cavity 406 is formed between the actuating body 403, the cavity frame 402 and the suspension plate 401 b.

Please refer to fig. 10A to 10C, which are schematic diagrams illustrating the operation of the blower micro-pump 40 of the present disclosure. Referring to fig. 9 and fig. 10A, the blower box micro pump 40 is fixedly disposed through a plurality of connecting members 401a, and an airflow chamber 407 is formed at the bottom of the air injection hole piece 401; referring to fig. 10B, when a voltage is applied to the piezoelectric plate 403c of the actuating body 403, the piezoelectric plate 403c begins to deform due to the piezoelectric effect and synchronously drives the adjustment resonator plate 403B and the piezoelectric carrier plate 403a, and at this time, the air hole piece 401 is driven by Helmholtz resonance (Helmholtz resonance) principle, so that the actuating body 403 moves upward. As the actuating body 403 moves upwards, the volume of the airflow chamber 407 on the bottom surface of the air jet hole sheet 401 increases, the internal air pressure forms negative pressure, and the air outside the blower box micropump 40 enters the airflow chamber 407 from the gap of the connecting piece 401a of the air jet hole sheet 401 due to the pressure gradient and is subjected to pressure concentration; finally, referring to fig. 10C, the gas continuously enters the gas flow chamber 407, so that the gas pressure in the gas flow chamber 407 is positive, and at this time, the actuating body 403 is driven by the voltage to move downward, so as to compress the volume of the gas flow chamber 407 and push the gas in the gas flow chamber 407, so that the gas entering the blower box micro-pump 40 is pushed and exhausted, thereby achieving the transmission flow of the gas.
