[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-Figure 5 As shown, the utility model provides a technical solution:

[0024] A breathing filter with a water collection function includes a housing 1, an air inlet end 2 is provided at the top of one side of the housing 1, an air outlet end 3 is provided at the top of the side of the housing 1 away from the air inlet end 2, a filter element 4 is installed on one side of the interior of the housing 1, a water outlet 5 is provided at the bottom end of the interior of the housing 1, slots 6 are provided on both sides of the bottom end of the interior of the housing 1, a water collection cup 7 is provided inside the housing 1, insert rings 8 are fixedly provided at both ends of the top of the water collection cup 7, and a connecting mechanism is provided between the interior of the slot 6 and the insert ring 8;

[0025] Through the above scheme, the breathing air enters the housing 1 from the air inlet end 2, is filtered by the filter element 4, and is discharged from the housing 1 from the air outlet end 3. As the filter element 4 is used for a long time, condensed water will adhere to it. The condensed water will flow along the filter element 4 and the inner wall of the housing 1 from the water outlet 5 to the water collection cup 7 and be collected, thereby realizing the water collection function of the breathing filter;

[0026] In this embodiment, preferably, the connecting mechanism includes a pressing block 9, a connecting groove 10, a first spring 11, a first movable plate 12, a connecting rod 13 and a clamping groove 14. A pressing block 9 is movably provided on one side of the slot 6 through the mounting hole. A connecting groove 10 is provided inside one end of the pressing block 9. A first spring 11 is installed at one end inside the connecting groove 10. A first movable plate 12 is provided at one end of the first spring 11 inside the connecting groove 10. A connecting rod 13 is fixedly provided on one side of the first movable plate 12. One end of the connecting rod 13 passes through the pressing block 9 through the mounting hole and is fixedly connected to the housing 1. A clamping groove 14 is provided on the end of the pressing block 9 away from the connecting groove 10. The top of the plug ring 8 passes through the clamping groove 14 and is clamped with the inner wall of the clamping groove 14;

[0027] Through the above solution, the use of the connecting mechanism in conjunction with the inserting ring 8 allows the operator to easily remove the water collecting cup 7 during long-term use of the breathing filter without taking too many steps and effort. When assembling the water collecting cup 7, the assembly can be completed only by the step of plugging it in, thereby making the breathing filter more convenient to use.

[0028] In this embodiment, preferably, the bottom surface of the pressing block 9 located at the bottom of the clamping groove 14 is inclined;

[0029] Through the above solution, when the top of the insert ring 8 hits the inclined surface, the pressing block 9 can be driven to be displaced by force, so that the insert ring 8 can automatically hit the inner wall of the clamping groove 14 during the insertion process;

[0030] In this embodiment, preferably, a sealing ring 15 is provided on the inner wall of the top of the water collecting cup 7;

[0031] Through the above solution, the sealing ring 15 ensures that the water collecting cup 7 will not leak when assembled and used;

[0032] In this embodiment, preferably, an adjustment plate 16 is provided inside the water outlet 5 through a rotating shaft, a receiving groove 17 is provided on one side of the outer side of the housing 1, and a knob 18 is provided inside the receiving groove 17 at one end of the rotating shaft where the adjustment plate 16 is located;

[0033] Through the above solution, the use of the regulating plate 16 can control the opening and closing of the water outlet 5, so that during daily use, the condensed water in the water collection cup 7 will not flow back into the housing 1 due to the inversion of the filter, ensuring the long-term use effect of the breathing filter;

[0034] In this embodiment, preferably, limit plates 19 are provided on both sides of the water outlet 5 at the upper and lower ends of the adjustment plate 16;

[0035] Through the above solution, the setting of the limiting plate 19 can limit the closed adjustment plate 16, thereby ensuring the functionality of the limiting plate 19 in the closed state;

[0036] In this embodiment, preferably, square grooves 20 are formed at both upper and lower ends of the accommodating groove 17, a second spring 21 is installed at one end of the square groove 20, a second movable plate 22 is provided at one end of the second spring 21, and a limit block 23 is fixedly provided on the side of the second movable plate 22 away from the second spring 21. Fitting grooves 24 are formed on the upper and lower surfaces of the outer side of the knob 18, and one end of the limit block 23 passes through the housing 1 through the mounting hole and is located inside the fitting groove 24;

[0037] With the above solution, when the knob 18 is opened, when the stop block 23 is engaged in the engagement groove 24 under the force of the second spring 21, it indicates that the adjustment plate 16 is in a vertical state. At this time, the condensed water can be discharged normally from the water outlet 5. The subsequent operator only needs to apply greater force to turn the knob 18. The cooperation between the second spring 21 and the stop block 23 ensures that when the knob 18 is in the open state, it will not rotate due to accidental touch and affect the use of the adjustment plate 16.

[0038] When a breathing filter with a water collection function of this embodiment is used, the breathing gas enters the housing 1 from the air inlet end 2, is filtered by the filter element 4, and is discharged from the housing 1 from the air outlet end 3. As the filter element 4 is used for a long time, condensed water will adhere to it. The condensed water will flow from the water outlet 5 along the filter element 4 and the inner wall of the housing 1 into the water collection cup 7 and be collected, thereby realizing the water collection function of the breathing filter. When there is a lot of water in the water collection cup 7, the user only needs to press one end of the pressing blocks 9 on both sides synchronously to make the inserting ring 8 away from the inner wall of the clamping groove 14, and the water collection cup 7 can be directly collected. The cup 7 is removed. When the water collecting cup 7 needs to be assembled, it is only necessary to align the plug ring 8 on the water collecting cup 7 with the slot 6 to complete the plugging work. During the insertion process, the top of the plug ring 8 will first hit the inclined surface on the lower surface of the pressing block 9, so that the pressing block 9 is forced to move, so that the first movable plate 12 in the connecting groove 10 compresses the first spring 11. When the plug ring 8 is embedded in the clamping groove 14, the pressing block 9 will reset under the force of the first spring 11, so that the plug ring 8 is clamped with the inner wall of the clamping groove 14, thereby completing the assembly and fixation of the water collecting cup 7. During the process, the opening and closing of the water outlet 5 can be achieved by controlling the knob 18. When it is necessary to open, it is only necessary to control the adjustment plate 16 to rotate to block the space in the water outlet 5 by turning the knob 18. When it is necessary to open, the opposite operation can be performed. When it is necessary to close, the setting of the limit plate 19 can limit the closed adjustment plate 16, thereby ensuring the functionality of the limit plate 19 in the closed state and preventing the operator from over-turning and affecting the use of the limit plate 19. When opening, when the limit block 23 is snapped into the fitting groove under the action of the second spring 21 24, it indicates that the adjustment plate 16 is in a vertical state. At this time, the condensed water can be discharged normally from the water outlet 5. The subsequent operator only needs to apply greater force to turn the knob 18, so that the cooperation of the second spring 21 and the limit block 23 can ensure that when the breathing filter is in the open state, the knob 18 will not rotate due to accidental touch and affect the use of the adjustment plate 16. Therefore, when the breathing filter is not needed, the water outlet 5 can be closed, so that the condensed water in the water collection cup 7 will not flow back into the shell 1 due to the inversion of the filter, thereby ensuring the long-term use effect of the breathing filter.
