[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] The filter assembly and the ventilator thereof disclosed in the present invention are mainly used in scenarios where existing ventilator filter assemblies lack effective water vapor treatment measures.

[0024] Reference Figure 1-Figure 5 A filter assembly includes a mounting slot 3, a filter canister 7 is disposed in the mounting slot 3, a housing 5 is connected to one side of the filter canister 7 by bolts, a stabilizing frame 4 is disposed on the outside of the housing 5, a water vapor processing module 8 is disposed in the housing 5, a storage tank 6 is disposed below the stabilizing frame 4, and a fixing module 9 is disposed between the stabilizing frame 4 and the storage tank 6;

[0025] The water vapor processing module 8 includes a diffusion hopper 802 and a gathering hopper 804. The diffusion hopper 802 and the gathering hopper 804 are both provided with electric heating wires 806. A plurality of equally spaced heat plates 809 are provided between the diffusion hopper 802 and the gathering hopper 804. The heat plates 809 are each provided with a condensing pipe 811 outside.

[0026] The fixing module 9 includes two slots 902 and tenons 905 that are equidistantly distributed around the circumference.

[0027] Specifically, after the water vapor exhaled by the patient enters the shell 5 through the air guide port 801, the water vapor processing module 8 on the shell 5 heats, cools, condenses and reheats the water vapor, and collects the water vapor into the collection tank 805. The condensed water collected in the collection tank 805 will enter the storage tank 6. When the storage tank 6 is about to be full, the fixed module 9 is used to remove the full storage tank 6 and reinstall the empty storage tank 6. The device uses the water vapor processing module 8 to effectively block the water vapor generated by the patient's breathing, enhance the waterproofness of the ventilator body 1, thereby avoiding water vapor from entering the ventilator body 1, causing a short circuit in the circuit or even a fire, thereby improving the safety and service life of the ventilator.

[0028] Reference Figure 1-Figure 4 In a preferred embodiment, an air inlet 801 is provided on the side of the housing 5 close to the stabilizing frame 4, and a circular opening is provided on the side of the housing 5 away from the air inlet 801, which is connected to the filter tank 7. The exteriors of the diffusion hopper 802 and the gathering hopper 804 are both connected to the inner wall of the housing 5 by bolts. The gathering hopper 804 is connected to an insulation board 803 by bolts on the side close to the diffusion hopper 802. A circular groove is provided on the insulation board 803, which is connected to the gathering hopper 804. A notch is provided on the bottom of the housing 5. The slot is connected with a collecting groove 805 by bolts, and the outside of the shell 5 is fitted with the outside of the stabilizing frame 4; the outside of the shell 5 is connected with a driving motor 808 by bolts, and the output end of the driving motor 808 passes through the shell 5 and is connected to the mounting plate 807 by a coupling. The mounting plate 807 is slidably connected to the side opposite to the inner wall of the shell 5, and multiple heat spreaders 809 are connected to the side opposite to the mounting plate 807 by bolts, and the side opposite to the heat spreader 809 and the condenser 811 is connected to a static The outer portion of the electric patch 810 and the mounting plate 807 are connected to a toothed ring 812 by bolts; a round rod 814 is provided on the outer portion of the toothed ring 812, and the round rod 814 is connected to the inner wall of the housing 5 by bolts. The outer portion of the round rod 814 is rotatably connected to a transmission rod 815 through a bearing, and the outer portion of the transmission rod 815 contacts the outer portion of the teeth of the toothed ring 812. The outer portion of the round rod 814 is rotatably connected to a knocking rod 816 through a bearing, and a concave hole is provided on the knocking rod 816, and the inner wall of the concave hole is connected to The coil spring 817 is connected to the outside of the round rod 814 by bolts at one end of the coil spring 817 away from the inner wall of the recessed hole; the side of the mounting plate 807 close to the knocking rod 816 is connected to the contact frame 813 by bolts, and the end of the knocking rod 816 away from the round rod 814 contacts the outside of the contact frame 813, and the outside of the transmission rod 815 is connected to the transmission block 819 by bolts, and the outside of the knocking rod 816 is connected to the blocking block 818 by bolts, and the blocking block 818 is fitted with the side opposite to the transmission block 819.

[0029] Specifically, after the water vapor enters the shell 5 through the air guide port 801, the water vapor is first heated by the electric heating wire 806 in the diffusion bucket 802, so that the water vapor is more dispersed. After the water vapor passes through the diffusion bucket 802, the condenser 811 and the electrostatic patch 810 are started. The condenser 811 transfers the low temperature to the heat spreader 809, so that the water vapor condenses quickly when flowing through the heat spreader 809. The electrostatic patch 810 with static electricity absorbs the remaining water vapor and starts the drive motor 808. The drive motor 808 drives the mounting plate 807 to rotate, so that the drive motor 808 on the mounting plate 807 rotates to a position of ninety degrees. During the rotation of the mounting plate 807, the teeth on the gear ring 812 continuously lift the transmission rod 815 as it rotates. Under the contact between the transmission block 819 and the blocking block 818, the knocking rod 816 overcomes the torsion of the coil spring 817 and rotates outward to store energy. After the transmission rod 815 is disengaged from the teeth of the gear ring 812, the knocking rod 816 is quickly reset under the torsion of the coil spring 817, thereby knocking on the contact frame 813, causing the water droplets on the heat spreader 809 to fall along the vertical surface of the heat spreader 809 to the collecting tank 805, and the drive motor 808 is started again, so that the mounting plate 807 drives the heat spreader 809 to rotate back to its original position.

[0030] In a specific application scenario, the water vapor processing module 8 is mainly suitable for the water vapor processing link in the water vapor processing process, that is, the water vapor processing module 8 uses a grid-type heat spreader 809 to increase the contact area between the water vapor and the heat spreader 809, so that the adsorption force and low temperature brought by the electrostatic patch 810 and the condenser 811 can better convert the water vapor into water droplets, thereby improving the device's ability to intercept water vapor and improving the device's water vapor processing efficiency. The transmission rod 815 and the knocking rod 816 can be used to make the device vibrate the small water droplets attached to the heat spreader 809 to form large water droplets by gravity, so that the water droplets are quickly separated from the heat spreader 809, ensuring the continuity of the heat spreader 809 adsorbing water vapor.

[0031] Reference Figure 5 In a preferred embodiment, a fixing ring 901 is inserted into the outside of the storage tank 6, and two tenons 905 are connected to the outside of the storage tank 6 by bolts. Two slots 902 are both opened on the fixing ring 901, and the side of the fixing ring 901 opposite to the collecting groove 805 is connected by bolts. The top inner wall of the fixing ring 901 is connected to a spring 904 by bolts, and the end of the spring 904 close to the storage tank 6 is connected to a fitting pad 903 by bolts. The outside of the fitting pad 903 is slidably connected to the inner wall of the fixing ring 901, and the fitting pad 903 is fitted with the opposite side of the storage tank 6, and the outside of the tenon 905 on the same side is clamped with the inner wall of the slot 902.

[0032] Specifically, the water droplets in the collecting tank 805 will fall into the storage tank 6. When the storage tank 6 is about to be filled, grab the storage tank 6 and rotate it slightly to disengage the tenon 905 on the storage tank 6 from the slot 902, and remove the storage tank 6 from the fixing ring 901. After treating the water in the storage tank 6, align the storage tank 6 with the fixing ring 901 to overcome the elastic force of the spring 1 904 and gently push the fitting pad 903 upward so that the tenon 905 can be inserted into the slot 902. Slightly rotate the storage tank 6 to lock the tenon 905 in the slot 902.

[0033] In a specific application scenario, the fixing module 9 is mainly suitable for the fixing link in the fixing process, that is, the fixing module 9 uses the tenon 905 and the slot 902 to quickly enable the device to replace the storage tank 6, thereby avoiding the storage tank 6 from overflowing into the shell 5 after being full, which has an adverse effect on the water vapor processing capacity of the device.

[0034] Reference Figure 6 、 Figure 7 and Figure 8 A ventilator comprises a filter assembly as described above, a ventilator body 1, the ventilator body 1 is located outside the filter canister 7, a diffusion tube 12 is provided in the filter canister 7, a filter element 13 is provided outside the diffusion tube 12, the diffusion tube 12 is connected to the side opposite to the inner wall of the filter canister 7 by bolts, the filter element 13 is located in the filter canister 7, a circular hole is provided on the outside of the filter canister 7, a connecting tube 14 is connected to the inner wall of the circular hole by bolts, and a quick disassembly module 10 is provided on the outside of the filter canister 7, four symmetrical universal wheels 2 are provided at the bottom of the ventilator body 1, and the stabilizing frame 4 is connected to the side opposite to the ventilator body 1 by bolts.

The bolt is connected to a fitting frame 1009, the inner wall of the fitting frame 1009 is plugged into the outside of the filter tank 7, the inner wall of the fitting frame 1009 is connected to a spring 2 1010 by a bolt, the end of the spring 2 1010 close to the filter tank 7 is connected to a push plate 1011 by a bolt, the push plate 1011 is fitted with the side opposite to the filter tank 7, and the outside of the connecting rod 1008 is connected to an arc plate 1012 by a bolt; an orifice is provided on the arc plate 1012, the inner wall of the orifice is connected to a joint 1013 by a bolt, the outside of the joint 1013 is connected to three equidistantly distributed sealing rings 1014 by bolts, one end of the joint 1013 is plugged into the inner wall of the connecting pipe 14, and the other end is connected to the air supply pipe 11 by a bolt, the end of the air supply pipe 11 away from the joint 1013 is connected to the ventilator body 1, and the outside of the sealing ring 1014 is fitted with the inner wall of the connecting pipe 14.

[0036] Specifically, during the operation of the ventilator, the filter element 13 in the filter canister 7 will adsorb and filter impurities in the gas. After the filter canister 7 has been used for a period of time, the effectiveness of the filter element 13 will decline or even fail. The dial block 1005 is rotated 180 degrees to rotate the inclined surface block 1003 connected to the dial block 1005 to a state opposite to the inclined surface of the inclined surface block 2 1004. Under the action of the spring 2 1010, the engaging frame 1009 rebounds, so that the inclined surface block 2 1004 connected to the rectangular groove 1007 moves toward the inclined surface block 1003. 003, and finally the inclined surfaces of the inclined plane block 2 1004 and the inclined plane block 1 1003 are fitted together, the engaging frame 1009 is unplugged from the outside of the filter tank 7, and the arc plate 1012 connected to the connecting rod 1008 pulls the joint 1013 out of the connecting pipe 14, thereby disconnecting the gas connection, and taking the filter tank 7 out of the mounting groove 3 together with the shell 5, and after replacing the filter element 13 in the filter tank 7, follow the above steps and use the quick disassembly module 10 to re-fix the filter tank 7 in the mounting groove 3.

[0037] In a specific application scenario, the quick disassembly and assembly module 10 is mainly suitable for the quick disassembly and assembly link in the quick disassembly and assembly process, that is, the quick disassembly and assembly module 10 uses the rotation of the symmetrical bevel block 1003 and the bevel block 2 1004 to enable the engaging frame 1009 to fix the filter canister 7 while ensuring that the gas pipe 11 can connect the filter canister 7 with the ventilator body 1, which greatly simplifies the difficulty of replacing the filter canister 7, thereby effectively ensuring the gas quality provided by the ventilator body 1, protecting the user's personal safety, and improving the user experience.

[0038] Working principle: After the water vapor enters the shell 5 through the air guide port 801, the water vapor is first heated by the electric heating wire 806 in the diffusion bucket 802, so that the water vapor is more dispersed. After the water vapor passes through the diffusion bucket 802, the condenser 811 and the electrostatic patch 810 are started. The condenser 811 transfers the low temperature to the heat plate 809, so that the water vapor condenses quickly when flowing through the heat plate 809. The electrostatic patch 810 with static electricity absorbs the remaining water vapor and starts the drive motor 808. The drive motor 808 drives the mounting plate 807 to rotate, so that the drive motor 808 on the mounting plate 807 rotates to a position of ninety degrees. During the rotation of the mounting plate 807, the teeth on the gear ring 812 follow the rotation of the gear ring 812. The transmission rod 815 is continuously raised by the rotation. Under the contact between the transmission block 819 and the blocking block 818, the knocking rod 816 overcomes the torsion of the coil spring 817 and rotates outward to store energy. After the transmission rod 815 is disengaged from the teeth of the gear ring 812, the knocking rod 816 is quickly reset under the torsion of the coil spring 817, thereby knocking the contact frame 813, causing the water droplets on the heat plate 809 to fall along the vertical surface of the heat plate 809 to the collection tank 805. The driving motor 808 is started again to make the mounting plate 807 drive the heat plate 809 to rotate back to its original position. The water droplets in the collection tank 805 will fall into the storage tank 6. When the storage tank 6 is about to be filled, grab the storage tank 6 and rotate it slightly to make the storage tank 6 The tenon 905 on the top is disengaged from the slot 902, and the storage tank 6 is removed from the fixing ring 901. After treating the water in the storage tank 6, the storage tank 6 is aligned with the fixing ring 901 to overcome the elastic force of the spring 1 904 and gently push the fitting pad 903 upward so that the tenon 905 can be inserted into the slot 902. The storage tank 6 is slightly rotated to lock the tenon 905 in the slot 902. During the operation of the ventilator, the filter element 13 in the filter tank 7 will adsorb and filter impurities in the gas. After the filter tank 7 has been used for a period of time, the use effect of the filter element 13 will decline or even fail. The dial block 1005 is rotated 180 degrees so that the inclined block 1003 connected to the dial block 1005 is rotated to the inclined block 2. When the inclined surfaces of the filter tank 7 are relative to each other, the engaging frame 1009 rebounds under the action of the second spring 1010, so that the inclined surface block 2 1004 connected to the rectangular groove 1007 moves toward the inclined surface block 1 1003. Finally, the inclined surfaces of the second inclined surface block 1004 and the inclined surface block 1 1003 fit together, and the engaging frame 1009 is unplugged from the outside of the filter tank 7, and the arc plate 1012 connected to the connecting rod 1008 pulls the joint 1013 out of the connecting pipe 14, thereby disconnecting the gas connection, and remove the filter tank 7 from the mounting groove 3 together with the housing 5. After replacing the filter element 13 in the filter tank 7, follow the above steps and use the quick disassembly module 10 to re-fix the filter tank 7 in the mounting groove 3.
