Referring to fig. 1 to 9, an air quality detecting apparatus 1000 having a moisture separator according to a preferred embodiment of the present invention is illustrated.

The air quality detecting device 1000 with moisture separator comprises an air quality detecting device 1 and a moisture separator 50, wherein the air quality detecting device 1 comprises a housing 10, an air detecting main body 20, an air duct 30, a filtering unit 40 and a housing having an air inlet 101 and an air outlet 102, wherein one end of the air duct 30 is connected to the air inlet 101, and the other end of the air duct 30 is connected to the air outlet 102, wherein the air detecting main body 20 is disposed on the air duct 30 in a manner that at least a portion of the air detecting main body 20 is exposed to the air duct 30, and wherein the moisture separator 50 is connected to the air duct 30 to reduce moisture content in air. The housing 10 has a receiving chamber 100, and the filter unit 40 is located in the air duct 30 to filter the air entering the air duct 30.

Specifically, the moisture separator 50 includes an outer housing 51 and a filter member 52, wherein the outer housing 51 surrounds a ventilation passage 510, wherein the outer housing 51 has a first opening 512 and a second opening 513, and wherein the filter member 52 is retained in the ventilation passage 510. The moisture separator 50 has a ventilation chamber 511, wherein the ventilation chamber 511 is formed between an outer wall of the filter member 52 and an inner wall of the outer housing 51.

The filter element 52 includes a filtering sidewall 521 and a bottom wall 522 and has a filtering chamber 523 and a plurality of pores 524, wherein the pores 524 are formed in the filtering sidewall 521, the filtering sidewall 521 and the bottom wall 522 surround the filtering chamber 523, the pores 524 are formed in the filtering sidewall 521, the openings of the filtering chamber are directly communicated with the first opening 512, the bottom wall 522 is formed at one end of the filtering sidewall 521 adjacent to the second opening 513, air enters the filtering chamber 523 through the first opening 512, passes through the pores 524 of the filtering sidewall 521 to reach the ventilating chamber 511, and then exits the moisture separator from the second opening 513.

That is, the air directly enters the filter chamber 523 from the first opening 512 of the outer housing 51, the bottom wall 522 of the filter element 52 acts as a barrier to the flow of the air in the air advancing direction, and the air flows out in the radial direction of the filter element 52 and then enters the ventilation chamber 511 between the outer housing 51 and the filter element 52. In this process, the filter side wall 521 of the filter element 52 acts as a filter for the air.

In other words, the air enters the filter chamber 523 from the first opening 512, and flows in the radial direction of the filter element 52 due to the blocking action of the bottom wall 522 of the filter element 52 and the conduction action of the micro-holes 524 of the filter side wall 521. In relation to the ventilation duct 510 of the outer housing 51, the air flows radially through the filter side wall 521 of the filter element 52 in the ventilation duct 510. Here radial with respect to the axis of the ventilation channel 510. Preferably, the outer housing 51 and the filter element 52 are located on the same axis.

Specifically, when air is drawn into the filter chamber 523 from the first opening 512 of the outer housing 51, under the influence of the walls of the filter element 52, larger particles of the air can be trapped in the filter element 52 and can pass mostly through the pores 524 of the filter sidewall 521 of the filter element 52 into the ventilation chamber 511 between the filter element 52 and the outer housing 51. The micropores 524 are configured to have a predetermined size, and when the micropores 524 are large, the diameter of particles that can pass through the micropores 524 is correspondingly large, and when the micropores 524 are small, the diameter of particles that can pass through the micropores 524 is also correspondingly small.

Further, when the moisture in the air meets the blocking effect of the filter element 52 during the process of flowing from the filter chamber 523 to the ventilation chamber 511, the moisture interacts with the portion of the filter sidewall 521 of the filter element 52 around the micro-holes 524, so that the portion of the moisture in the air adheres to the filter sidewall 521, reducing the moisture content in the air, and thus reducing the influence on the working accuracy of the air quality detecting apparatus 1000 with the moisture separator in the subsequent operation.

The moisture separator 50 further includes a first connecting member 53 and a second connecting member 54, wherein the first connecting member 53 is connected to the outer housing 51 at the second opening 513 and one end of the first connecting member 53 is connected to the outside and the other end is connected to the ventilating chamber 511, wherein the second connecting member 54 is connected to the outer housing 51 at the first opening 512 and one end of the second connecting member 54 is connected to the outside and the other end is connected to the filtering chamber 523.

The moisture separator 50 can be used in cooperation with other devices connected thereto through the first and

second connectors

53 and 54 at both ends of the outer case 51.

Further, the first connecting member 53 includes a side wall 531 and a top wall 532, and has at least one through hole 533, wherein the top wall 532 is formed at an end of the side wall 531 adjacent to the filtering member 52, and the through hole 533 is formed at an end of the side wall 531 adjacent to the top wall 532. The through hole 533 of the first connecting member 53 is directly connected to the ventilation cavity 511, so that the air enters the filter cavity 523 from the first opening 512, reaches the ventilation cavity 511, and leaves the moisture separator through the through hole 533 of the sidewall 531 of the first connecting member 53.

Specifically, the first connector 53 has an air outlet channel 534, wherein the sidewall 531 and the top wall 532 surround the air outlet channel 534, and air enters the air outlet channel 534 of the first connector 53 through the through hole 533. The top wall 532 and the side wall 531 of the first connector 53 provide a blocking effect to air, which can be discharged to the outside only through the through hole 533 of the first connector 53.

The second connector 54 has an inlet channel 540, wherein the ventilation channel 510 is respectively connected to the inlet channel and the outlet channel 534, so that gas can enter the ventilation channel 510 from the outside through the inlet channel 540 and exit through the outlet channel 534. Wherein the air inlet passage 540 communicates with the outside and the filter chamber 523, and the air inlet passage 540 does not directly communicate with the ventilating chamber 511, but communicates with the ventilating chamber 511 through the filter chamber 523.

In some examples of the invention, the filter element 52 is coupled to the second connector 54. The filter member 52 may be integrally extended from the second connector 54, or may be detachably connected to the second connector 54. In other examples of the present invention, the filter member 52 is coupled to the first coupling member 53. The filter member 52 may be integrally extended from the first connecting member 53, or may be detachably connected to the first connecting member 53.

Further, the moisture separator 50 has a storage chamber 514, wherein the storage chamber 514 is provided below the ventilation channel 510, wherein the storage chamber 514 is used for storing the liquid generated in the ventilation channel 510.

Further, the moisture separator 50 comprises a drain valve 55 and a connector 551 having at least one drain opening 550 and a port 551, wherein the connector 551 is used for connecting the drain valve 55, and the drain opening 550 is formed around the connector 551 for draining water outwards. The drain 550 and the mouthpiece 551 are formed on a side wall of the outer housing 51, and the drain valve 55 is reciprocally coupled to the position of the mouthpiece 551. The drain valve 55 is switched between a closed state and an open state in accordance with the movement of the drain valve 55. When the drain valve 55 is in the closed state, moisture can flow from the drain opening 550 to the outside, and when the drain valve 55 is in the open state, moisture cannot flow from the drain opening 550 to the outside. Wherein the drain valve 55 is mounted below the storage chamber 514 for discharging the liquid in the storage chamber 514.

It is noted that when a large amount of moisture accumulates in the drain valve 55, the drain valve 55 moves by the gravity of the moisture to discharge the moisture from the drain opening 550, and when a small amount of moisture accumulates in the drain valve 55, the drain valve 55 closes the drain opening 550 to accumulate a larger amount of moisture.

Specifically, the drain valve 55 includes a connection rod 552 and a closing cover 553, and the connection rod 552 is disposed to extend outward from one side of the closing cover 553. The connecting rod 552 includes a connecting rod body 554 and a stop end 555, wherein the stop end 555 is disposed at one end of the connecting rod body 554, and the stop end 555 is sized larger than the hub 551, the connecting rod body 554 being sized to fit within the hub 551 to enable the connecting rod body 554 to move back and forth within the hub 551. The closure 553 is configured to be larger than the interface 551. The blocking end 555 and the closing cap 553 are respectively located at both ends of the connecting rod body 554 so that the drain valve 55 can be held at the mouthpiece 551 not to be removed from the mouthpiece 551. When the drain valve 55 is in the closed state, the closing cover 553 covers all the drain openings 550 so that moisture cannot be discharged, and when the drain valve 55 is in the open state, the closing cover 553 of the drain valve 55 is separated from the drain openings 550 so that moisture is discharged from the drain openings 550.

It is worth mentioning that the drain valve 55 is capable of automatically draining water. This reduces the time cost for the user to be concerned about whether the moisture separator 50 needs to be drained.

Specifically, the blocking end 555 of the drain valve 55 is located in the ventilation passage 510 of the outer housing 51, the closing cover 553 is located outside the outer housing 51, and a side of the closing cover 553 facing the outer housing 51 communicates with the ventilation passage 510, and a side of the closing cover 553 facing away from the outer housing 51 communicates with the outside.

When the moisture separator 50 is in operation, due to the influence of the gas flow rate, the pressures inside and outside the outer shell 51 are different, and the pressure outside the outer shell 51 is greater than the pressure inside the outer shell 51, so that the closing cover 553 receives a force from the outside of the outer shell 51 to the inside of the outer shell 51, and the closing cover 553 can be tightly attached to the outer shell 51. In this process, the closing cap 553 can prevent moisture from flowing out of the drain opening 550.

With respect to the closure 553, which is maintained in the closed state primarily by virtue of a balance between the weight of the closure 553 itself and the force provided by the difference between the internal and external air pressures, once the weight of the moisture retained at the closure 553, plus the weight of the closure 553 itself, exceeds the force that can be provided by the difference between the internal and external air pressures, the closure 553 will exit the drain opening 550 such that the moisture is automatically drained from the drain opening 550.

It is worth mentioning that, in the process of opening and closing the vehicle door or the vehicle window, the change of the pressure difference between the inside and the outside of the vehicle may switch the closing cover 553 between the closing state and the opening state.

Preferably, the moisture separator 510 is adapted to be used in a horizontal state to allow moisture to reach the drain valve 55 by gravity. The horizontal state here means that the outer case 51 and the filter member 52 are in a horizontal position so that air enters the moisture separator 50 in a horizontal direction.

The air detecting body 20 includes a circuit board unit 22 and a detecting unit 23, wherein the detecting unit 23 is communicably connected to the circuit board unit 22, wherein the detecting unit 23 is used for detecting air quality, and the circuit board unit 22 is capable of receiving data from the detecting unit 23 and performing subsequent processing.

The air detecting body 20 further includes an air extracting unit 21, wherein the air extracting unit 21 is used for providing a thrust, and the air extracting unit 21 may be a fan, such as an axial flow fan or a mixed flow fan. The air extracting unit 21 is located at the air duct 30.

In this example, after the air enters the air duct 30 through the air inlet 101, the air bypasses the circuit board unit 22 by the thrust action of the air pumping unit 21 and then reaches the detection unit 23 to be detected, and finally exits the air quality detection device 1000 with the moisture separator from the air outlet 102.

That is, the air duct 30 is formed on both sides of the circuit board unit 22 to facilitate reduction in the size of the air duct 30 in the length and width directions.

The moisture separator 50 is installed at the position of the air inlet 101 so that air can be at least partially removed of moisture at the position of the moisture separator before entering the air inlet 101.

The housing 10 has a top surface 11, a bottom surface 12 and a side surface 13, wherein the top surface 11 and the bottom surface 12 are oppositely disposed and the side surface 13 is formed between the top surface 11 and the bottom surface 12. The housing 10 has a receiving cavity 100, and the top surface 11, the bottom surface 12 and the side surface 13 surround the receiving cavity 100.

Referring to fig. 3D and 3E, a modified embodiment of the moisture separator 50 according to the preferred embodiment of the present invention is shown, and the present embodiment is different from the above embodiment in the filter member 52.

The moisture separator 50 includes an outer housing 51 and a filter member 52 and has a ventilation passage 510, wherein the filter member 52 is held in the ventilation passage 510. The outer housing 51 surrounds the ventilation channel 510, wherein the outer housing 51 has a first opening 512 and a second opening 513, and air enters the ventilation channel 510 through the first opening 512 and then exits the ventilation channel 510 through the second opening 513. The outer housing 51 has a ventilation chamber 511, wherein the ventilation chamber 511 is formed between an outer wall of the filter member 52 and an inner wall of the outer housing 51.

The filter element 52 comprises a filter side wall 521 and a bottom wall 522 and has a filter chamber 523 and a plurality of pores 524, wherein the filter side wall 521 and the bottom wall 522 surround the filter chamber 523, and the pores 524 are formed in the filter side wall 521, wherein the filter chamber opening is formed adjacent to one end of the second connecting element 54, so that the air directly enters the filter chamber 523 from the first opening 512.

The filtering sidewall 521 is configured as a concave curved structure. The filtering sidewall 521 includes a first partial filtering sidewall 5211 and a second partial filtering sidewall 5212, wherein the junction of the first partial filtering sidewall 5211 and the second partial filtering sidewall 5212 is disposed to be concave toward the ventilation passage 510. The first partial filtering sidewall 5211 is disposed adjacent to the first opening 512, and the second partial filtering sidewall 5212 is disposed adjacent to the second opening 513.

When the air enters the filter cavity 523 from the first opening 512, the air first contacts the first partial filtering sidewall 5211, the first partial filtering sidewall 5211 and the advancing direction of the air form an acute angle, so that the air immediately encounters the blockage of the first partial filtering sidewall 5211 after entering the filter cavity 523, and the moisture in the air can be trapped by the first partial filtering sidewall 5211. It is noted that, when the moisture separator 50 is horizontally placed, the included angle of the first partial filtering sidewall 5211 and the vertical direction is an acute angle, so that the moisture trapped in the first partial filtering sidewall 5211 more easily leaves the first partial filtering sidewall 5211. Another portion of the air which does not encounter the obstruction of the first partial filtering sidewall 5211 continues to advance until it encounters the obstruction from the bottom wall 522, the air changes the direction of advance from the second partial filtering sidewall 5212 exiting the filtering chamber 523 to the ventilating chamber 511, and likewise, when the moisture separator 50 is placed horizontally, the included angle between the first partial filtering sidewall 5211 and the vertical direction is an acute angle, so that the moisture trapped in the second partial filtering sidewall 5212 is more likely to exit the second partial filtering sidewall 5212 under the action of gravity.

The outer housing 51 has a storage chamber 514, and moisture trapped by the filter element 52 is retained in the storage chamber 514. When the moisture separator 50 is in a horizontal use state, i.e., the filter member 52 is in a horizontal position and both ends of the outer housing 51 are substantially in the same horizontal position, the storage chamber 514 is formed at a lower portion of the ventilation passage 510 of the outer housing 51, and moisture trapped by the filter member 52 naturally falls down to the storage chamber 514 by gravity.

The moisture separator 50 further includes a first connecting member 53 and a second connecting member 54, wherein the first connecting member 53 is connected to the outer housing 51 at the second opening 513 and one end of the first connecting member 53 is connected to the outside and the other end is connected to the ventilating chamber 511, wherein the second connecting member 54 is connected to the outer housing 51 at the first opening 512 and one end of the second connecting member 54 is connected to the outside and the other end is connected to the filtering chamber 523. The first connecting member 53 includes a side wall 531 and a top wall 532, and has at least one through hole 533, wherein the top wall 532 is formed at one end of the side wall 531 adjacent to the filter member 52, and the through hole 533 is formed at one end of the side wall 531 adjacent to the top wall 532. The first connector 53 has an outlet channel 534, and the second connector 54 has an inlet channel 540.

The moisture separator 50 comprises a drain valve 55 and a connector 551, wherein the connector 551 is used for connecting the drain valve 55, and the drain 550 is formed around the connector 551 for draining water outwards. The drain valve 55 includes a connection rod 552 and a closing cover 553, and the connection rod 552 is disposed to extend outward from one side of the closing cover 553. The connecting rod 552 includes a connecting rod body 554 and a stop end 555, wherein the stop end 555 is disposed at one end of the connecting rod body 554, and the stop end 555 is sized larger than the hub 551, the connecting rod body 554 being sized to fit within the hub 551 to enable the connecting rod body 554 to move back and forth within the hub 551.

Referring to fig. 3F, a modified embodiment of the moisture separator 50 according to the above preferred embodiment of the present invention is shown, and the difference between the present embodiment and the above embodiment is the drain opening 550.

The drain opening 550 is formed in a housing side wall 5111 of the housing body 51, and the drain opening 550 is formed to protrude outward from the housing side wall 5111 so that the drain opening 550 is located at a lower position of the housing side wall 5111 so that moisture can be collected to the drain opening 550 by gravity. It is also understood that the housing sidewall 5111 has at least one guiding sidewall 51111, such as an inclined or arc shape, such that the moisture is automatically guided to the water outlet 550 along the guiding sidewall 51111 due to gravity. In this embodiment, the drain opening 550 is located near the second opening 513.

Referring to fig. 3G, a modified embodiment of the moisture separator 50 according to the present invention, which differs from the previous embodiment in the location of the drain opening 550, in this case the drain opening 550 is located below the filter element 52 so that the water is separated from the filter element 52 and then directly to the drain opening 550.

Referring to FIG. 3H, a moisture separator 50 according to another preferred embodiment of the present invention is illustrated.

The moisture separator 50 includes an outer housing 51, a filter member 52 and a filter member having a ventilation passage 510, a first opening 512 and a second opening 513, wherein the outer housing 51 surrounds the ventilation passage 510, the filter member 52 is held in the ventilation passage 510, and air enters the ventilation passage 510 through the first opening 512 and exits the ventilation passage 510 through the second opening 513. The filter element 52 includes a filter sidewall 521 and a bottom wall 522 and has a filter chamber 523, wherein the bottom wall 522 covers one end of the filter sidewall 521, the filter sidewall 521 surrounds the filter chamber 523, and the filter chamber opening is formed at the other end of the filter sidewall 521.

The filter chamber opening faces the second opening 513 and the bottom wall 522 of the filter element 52 faces the first opening 512. The moisture separator 50 has a ventilation chamber 511, wherein the ventilation chamber 511 is formed between the filter element 52 and the outer housing 51, and the ventilation chamber 511 is directly communicated with the first opening 512 so that air directly enters between the filter element 52 and the outer housing 51 through the first opening 512. The ventilation chamber 511 is indirectly connected to the second opening 513 such that air passes through the filter chamber 523 to the second opening 513 after passing through the ventilation chamber 511.

Specifically, the filter element 52 has a plurality of pores 524, wherein the pores 524 are formed in the filter sidewall 521 of the filter element 52. During the use of the moisture separator 50, when air directly enters the ventilation chamber 511 from the first opening 512, a part of the moisture is blocked by the filter sidewall 521 of the filter element 52 near the micro-holes 524, and the rest of the air enters the filter chamber 523 of the filter element 52 through the micro-holes 524 of the filter sidewall 521 of the filter element 52 and then exits the moisture separator 50 through the second opening 513.

During this process, some large particles in the air are also blocked outside the filter element 52, such as large particles like hair, gravel, etc. The filter member 52 not only filters moisture in the air but also filters large particulate impurities in the air having a particle size larger than the fine pores 524.

Preferably, in this example, the moisture separator 50 is vertically disposed, that is, the air inlet direction and the air outlet direction of the air are both in a vertical direction. The moisture blocked by the filter side wall 521 of the filter member 52 increases in weight as the amount increases, and after a certain volume is accumulated, the moisture falls down to the bottom end of the outer case 51 along the filter side wall 521.

The outer housing 51 has a storage chamber 514, wherein the storage chamber 514 is formed at an end of the outer housing 51 adjacent the first opening 512, and moisture trapped by the filter element 52 is retained in the storage chamber 514. When the moisture separator 50 is in a vertical use state, i.e., the filter member 52 is in a vertical position, and the end of the outer housing 51 adjacent to the first opening 512 is in a lower end, moisture trapped by the filter member 52 naturally falls down to the storage chamber 514 by gravity. The storage chamber 514 is formed around the first opening 512 and is formed by an end portion of the outer housing 51 adjacent to one end of the first opening 512.

The moisture separator 50 further comprises a first connector 53 and a second connector 54, wherein the first connector 53 is connected to the outer housing 51 at the first opening 512, one end of the first connector 53 is connected to the outside, and the other end of the first connector 53 is connected to the ventilation chamber 511, wherein the second connector 54 is connected to the outer housing 51 at the second opening 513, one end of the second connector 54 is connected to the air detection body, and the other end of the second connector 54 is connected to the filter chamber 523.

second connectors

53 and 54 at both ends of the outer case 51.

Further, the first connecting member 53 includes a side wall 531 and a top wall 532, and has at least one through hole 533, wherein the top wall 532 is formed at an end of the side wall 531 adjacent to the filtering member 52, and the through hole 533 is formed at an end of the side wall 531 adjacent to the top wall 532. The through hole 533 of the first connection member 53 is directly communicated with the ventilation chamber 511. The first connector 53 is received in the first opening 512, and the air directly enters the ventilation chamber 511 through the through hole 533 of the first connector 53 and then exits the moisture separator 50 through the micro holes 524 of the filter sidewall 521 of the filter element 52. In this example, the top wall 532 of the first connector 53 is supported from the bottom wall 522 of the filter element 52.

Specifically, the first connector 53 has an air outlet channel 534, wherein the sidewall 531 and the top wall 532 surround the air outlet channel 534, and air enters the air outlet channel 534 of the first connector 53 through the through hole 533. The top wall 532 and the side wall 531 of the first connector 53 provide a barrier to air that can only pass through the through-hole 533 of the first connector 53 to the vent passage 510 of the outer housing 51.

It is worth mentioning that the first connecting member 53 acts as a buffer for the incoming air, and the direction of the flow of the air is changed through the through hole 533 of the first connecting member 53 from the air outlet channel 534 along the first connecting member 53 to the radial direction along the air outlet channel 534, so that the air passes through the micro holes 524 of the filtering sidewall 521 of the filter element 52 along an angle. That is, within the ventilation chamber 511, the air flow direction is at an angle to the filter sidewall 521. With the abrupt change of the flow direction of the air in the ventilation chamber 511, the air moves more intensely, and moisture in the air is more easily condensed to be trapped by the filtering sidewall 521. In other words, the moisture filtering efficiency of the filter member 52 is increased by the first connecting member 53.

The second connection member 54 has an intake passage 540, wherein the intake passage 540 communicates with the outside and the filter chamber 523, and the intake passage 540 does not directly communicate with the ventilating chamber 511, but communicates with the ventilating chamber 511 through the filter chamber 523.

Further, the moisture separator 50 comprises a drain valve 55 and a connector 551 having at least one drain opening 550 and a port 551, wherein the connector 551 is used for connecting the drain valve 55, and the drain opening 550 is formed around the connector 551 for draining water outwards. The drain 550 and the connector 551 are both formed at an end of the outer housing 51 adjacent to the first opening 512, that is, at an end wall of the outer housing 51 adjacent to the first opening 512, and the drain valve 55 is reciprocally connected to the connector 551. The drain valve 55 is switched between a closed state and an open state in accordance with the movement of the drain valve 55. When the drain valve 55 is in the closed state, moisture can flow from the drain opening 550 to the outside, and when the drain valve 55 is in the open state, moisture cannot flow from the drain opening 550 to the outside.

It is worth mentioning that the drain valve 55 is capable of automatically draining water. This reduces the time cost for the user to be concerned about whether the moisture separator needs to be drained.

When the moisture separator 50 is in operation, due to the influence of the gas flow rate, the pressures inside and outside the outer shell 51 are different, and the pressure outside the outer shell 51 is greater than the pressure inside the outer shell 51, so that the sealing cover 553, which may be implemented as an elastic material such as a gel material, receives a force from the outside of the outer shell 51 toward the inside of the outer shell 51, so that the sealing cover 553 can be tightly attached to the outer shell 51. In this process, the closing cap 553 can prevent moisture from flowing out of the drain opening 550.

It is understood that in some examples of the invention, the hub 551 may be used as the drain 550 and the hub 551 is larger than the connector body 554 so that moisture can flow through the space between the hub 551 and the connector rod 5521 to the closure 553 when the blocking end 555 is not in contact with the hub 551.
