Description

Technical Field

[0001] The utility model relates to the technical field of foaming filters, in particular to a humidifying bottle oxygen foaming filter which is convenient to install. Background Art

[0002] A humidifying bottle is a device for increasing the humidity of gas, usually used in conjunction with breathing equipment, such as a ventilator or an oxygen delivery system. Its working principle is to heat water to generate water vapor, making the passing gas moist. The oxygen foaming filter in the humidifying bottle, as a filtering component, filters the oxygen entering the humidifying bottle.

[0003] In the prior art, the air pipe and the foaming filter in the humidifying bottle are mostly fixedly designed. This enables the replacement of only the air pipe when replacing the foaming filter in the humidifying bottle. Since the air pipe is often fixedly connected to the screw cap through an external buckle, and the air pipe is not thick, the buckle is also small. This requires the user to be careful not to drop the buckle while ensuring stable fixation, making the fixation process of the foaming filter rather troublesome and inconvenient for replacing and installing the filter. Summary of the Utility Model

[0004] In view of the deficiencies of the prior art, the technical solution adopted by the utility model to solve its technical problems is: a humidifying bottle oxygen foaming filter which is convenient to install, comprising: a water bottle; a screw cap, the outer wall of the screw cap is threadedly connected to the outer wall of the water bottle; a safety valve, the safety valve is used for pressure relief, and the outer wall of the safety valve is fixedly connected to the inner wall of the screw cap; an installation device, the installation device is used to assist the installation components of the humidifying bottle, and the outer wall of the installation device is fixedly connected to the outer wall of the screw cap; a meter, the bottom of the meter is fixedly connected to the top of the installation device; a locking device, the locking device is used to lock the internal components of the installation device, and the outer wall of the locking device is fixedly connected to the outer surface of the screw cap; the installation device includes a connecting cylinder, the inner wall of the connecting cylinder is slidably connected with an air pipe, the top of the air pipe is inserted with a connecting pipe, the inner wall of the connecting cylinder is fixedly connected with a first compression spring, one end of the first compression spring close to the air pipe is fixedly connected with a sliding buckle, the end of the sliding buckle away from the first compression spring is fixedly connected with a pushing column, the outer wall of the connecting pipe is slidably connected with the sliding buckle through a buckle groove, and the buckle groove is formed in the wall of the connecting pipe. The bottom of the connecting pipe is fixedly connected with a fixed filter element. The air pipe is fixed by pushing the sliding buckle by the first compression spring to fix the buckle groove outside the air pipe, making the replacement and installation process convenient.

[0005] Preferably, the bottom of the meter is fixedly connected to the top of the connecting pipe, the outer wall of the connecting pipe is fixedly connected to the inner wall of the screw cap, both ends of the connecting cylinder are fixedly connected to the inner wall of the screw cap, the outer wall of the push rod slides on the inner wall of the screw cap, a locking hole is formed in the wall of the push rod, the outer wall of the connecting pipe contacts the bottom of the connecting cylinder, the outer wall of the sliding buckle slides on the inner wall of the connecting cylinder, and a flower-shaped pipe is fixedly connected to the inner wall of the connecting pipe. The oxygen in the ventilation pipe is dispersed and flowed through the internal shape of the flower-shaped pipe, so that the oxygen entering the filter element overflows from the filter element more evenly, thereby making the filter element foam evenly and reducing the use noise of the humidifying bottle.

[0006] Preferably, the locking device includes a rotating ring. A reserved groove is formed in the wall of the rotating ring. A support platform is arranged outside the rotating ring. A second compression spring is fixedly connected to the bottom of the inner wall of the support platform. The top of the second compression spring is fixedly connected to a push plate. The outer wall of the rotating ring rotates on the outer wall of the screw cap. The outer wall of the screw cap is fixedly connected to the outer wall of the support platform. The inner wall of the support platform slides on the outer wall of the push plate. After installing or replacing the ventilation pipe and the filter element, the push plate enters the locking hole on the push rod, making it difficult for the push rod to move before contact and fixation, thereby preventing the push rod from accidentally touching and causing the sliding buckle to lose its fixing effect.

[0007] The beneficial effects of the present utility model are as follows:

[0008] 1. By setting the installation device, the present utility model fixes the ventilation pipe by pushing the sliding buckle with the first compression spring to fix the buckle groove on the outside of the ventilation pipe, making the replacement and installation processes convenient.

[0009] 2. By setting the flower-shaped pipe inside the ventilation pipe, the present utility model guides and divides the oxygen entering the ventilation pipe. The oxygen in the ventilation pipe is dispersed and flowed through the internal shape of the flower-shaped pipe, so that the oxygen entering the filter element overflows from the filter element more evenly, thereby making the filter element foam evenly and reducing the use noise of the humidifying bottle.

[0010] 3. By setting the locking device, after installing or replacing the ventilation pipe and the filter element, the push plate enters the locking hole on the push rod, making it difficult for the push rod to move before contact and fixation, thereby preventing the push rod from accidentally touching and causing the sliding buckle to lose its fixing effect.

[0018] Please refer to Figure 1 - Figure 4, the present utility model provides a technical solution: a humidifying bottle oxygen foaming filter element that is easy to install, including: a water bottle 1; a screw cap 2, the outer wall of the screw cap 2 is threadedly connected to the outer wall of the water bottle 1; a safety valve 3, the safety valve 3 is used for pressure relief, and the outer wall of the safety valve 3 is fixedly connected to the inner wall of the screw cap 2; an installation device 5, the installation device 5 is used to assist the installation components of the humidifying bottle, and the outer wall of the installation device 5 is fixedly connected to the outer wall of the screw cap 2; a meter 4, the bottom of the meter 4 is fixedly connected to the top of the installation device 5; a locking device 6, the locking device 6 is used to lock the internal components of the installation device 5, and the outer wall of the locking device 6 is fixedly connected to the outer surface of the screw cap 2; the installation device 5 includes a connecting cylinder 51, a ventilation pipe 52 is slidably connected to the inner wall of the connecting cylinder 51, a connecting pipe 53 is inserted at the top of the ventilation pipe 52, a first compression spring 55 is fixedly connected to the inner wall of the connecting cylinder 51, a sliding buckle 56 is fixedly connected to one end of the first compression spring 55 close to the ventilation pipe 52, a push column 57 is fixedly connected to one end of the sliding buckle 56 away from the first compression spring 55, the outer wall of the connecting pipe 53 is slidably connected to the sliding buckle 56 through a buckle groove 54, and the buckle groove 54 is opened in the wall of the connecting pipe 53, a fixed filter element 59 is fixedly connected to the bottom of the connecting pipe 53. When installing the ventilation pipe 52, after pressing the push column 57 into the connecting cylinder 51, insert the end of the ventilation pipe 52 away from the fixed filter element 59 into the through hole in the middle of the connecting cylinder 51 until the protruding part of the ventilation pipe 52 touches the bottom of the connecting cylinder 51 and then stop. At this time, the ventilation pipe 52 enters the pipeline in the connecting cylinder 51 and is limited by the connecting cylinder 51. Therefore, at this time, the ventilation pipe only has freedom in the up and down directions. At this time, release the pressed push column 57. When releasing the thrust, the previously compressed first compression spring 55 is also released, thereby pushing the sliding buckle 56 to move in the direction of the push column 57. At this time, the sliding buckle 56 enters the buckle groove 54 of the ventilation pipe 52, so that the freedom in the up and down directions of the ventilation pipe 52 is also restricted.

[0019] The bottom of the meter 4 is fixedly connected to the top of the connecting pipe 53, the outer wall of the connecting pipe 53 is fixedly connected to the inner wall of the screw cap 2, both ends of the connecting cylinder 51 are fixedly connected to the inner wall of the screw cap 2, the outer wall of the push column 57 is slidably connected to the inner wall of the screw cap 2, a locking hole 58 is opened in the wall of the push column 57, the outer wall of the connecting pipe 53 is in contact with the bottom of the connecting cylinder 51, the outer wall of the sliding buckle 56 is slidably connected to the inner wall of the connecting cylinder 51, a flower-shaped pipe 510 is fixedly connected to the inner wall of the connecting pipe 53. After the gas entering the ventilation pipe 52 enters the flower-shaped pipe 510, it will fill the petal positions of the flower-shaped holes of the flower-shaped pipe 510. Since the petals of the flower-shaped pipe 510 are evenly distributed, the air flow at each petal position will be evenly transported to the position of the fixed filter element 59, making the air flow entering the fixed filter element 59 more stable, making the air flow overflowing from the fixed filter element 59 more uniform, thereby making the fixed filter element 59 foam evenly and reducing the bubble size when the fixed filter element 59 foams. Embodiment

[0020] Please refer to Figure 1 - Figure 5 Figure 5 , the present utility model provides a technical solution: on the basis of Embodiment 1, the locking device 6 includes a swivel ring 61. A reserved groove 62 is formed in the wall of the swivel ring 61. A support platform 63 is arranged outside the swivel ring 61. The bottom of the inner wall of the support platform 63 is fixedly connected with a second compression spring 64. The top of the second compression spring 64 is fixedly connected with a push plate 65. The outer wall of the swivel ring 61 is rotatably connected with the outer wall of the rotary cover 2. The outer wall of the rotary cover 2 is fixedly connected with the outer wall of the support platform 63. The inner wall of the support platform 63 is slidably connected with the outer wall of the push plate 65. When the sliding buckle 56 completely clamps the ventilation pipe 52, the locking hole 58 of the push rod 57 is exactly above the push plate 65. When starting to use the locking device 6, rotate the swivel ring 61 to drive the reserved groove 62 on the swivel ring 61 to reach the position of the push plate 65. The previously compressed second compression spring 64 will push the push plate 65 to move. Due to the limiting effect of the support platform 63, the push plate 65 moves vertically upward. When the push plate 65 enters the locking hole 58 at this time, it means that the ventilation pipe 52 is stably connected at this time. Since the push plate 65 restricts the movement of the push rod 57, the ventilation pipe 52 is prevented from falling off when the push rod 57 is accidentally touched and impacted.

[0021] Working principle:

[0022] When in use, the installation device 5 is set to fix the ventilation pipe 52. For the ventilation pipe 52 that needs to be replaced and the fixed filter element 59, since the fixed filter element 59 is fixed on the ventilation pipe 52, when replacing the fixed filter element 59, only the ventilation pipe 52 needs to be replaced. When installing the ventilation pipe 52, after pressing the push rod 57 into the connection cylinder 51, insert the end of the ventilation pipe 52 away from the fixed filter element 59 into the through hole in the middle of the connection cylinder 51 until the protruding part of the ventilation pipe 52 touches the bottom of the connection cylinder 51 and then stop. During this process, the ventilation pipe 52 is inserted into the connection pipe 53, and the connection pipe 53 is externally connected to the meter 4. At this time, the ventilation pipe 52 enters the pipeline in the connection cylinder 51 and is limited by the connection cylinder 51. So at this time, the ventilation pipe only has freedom in the up and down directions. At this time, release the pressed push rod 57. When releasing the thrust, the previously compressed first compression spring 55 is also released, thereby pushing the sliding buckle 56 to move towards the push rod 57. At this time, the sliding buckle 56 enters the buckle groove 54 of the ventilation pipe 52, so that the freedom of the ventilation pipe 52 in the up and down directions is also limited, thereby achieving the purpose of fixing the ventilation pipe 52.

[0023] A flower-shaped tube 510 is provided. The through-hole in the inner wall of the flower-shaped tube 510 is flower-shaped. After the gas entering the air vent pipe 52 enters the flower-shaped tube 510, it will fill the petal positions of the flower-shaped holes in the flower-shaped tube 510. Since the petals of the flower-shaped tube 510 are evenly distributed, the air flow at each petal position will be evenly transported to the position of the fixed filter element 59, making the air flow entering the fixed filter element 59 more stable, and making the air flow overflowing from the fixed filter element 59 more uniform. As a result, the fixed filter element 59 produces bubbles evenly, reducing the size of the bubbles when the fixed filter element 59 produces bubbles. By reducing the size of the bubbles, the sound when the bubbles burst is reduced, reducing the noise generated by the humidifying bottle and making the pressure inside the water bottle 1 relatively stable, and reducing the usage frequency of the safety valve 3.

[0024] A locking device 6 is provided to prevent the push column 57 from being accidentally touched and causing the air vent pipe 52 to fall off. After the sliding buckle 56 is stuck on the buckle groove 54, the push column 57 is located outside the rotary cap 2. In the unused state of the locking device 6, the bottom of the rotary ring 61 abuts against the top of the push plate 65, and at this time, the push plate 65 and the support platform 63 compress the second compression spring 64. When starting to use the locking device 6, rotate the rotary ring 61 to drive the reserved groove 62 on the rotary ring 61 to reach the position of the push plate 65. The previously compressed second compression spring 64 will push the push plate 65 to move. Due to the limiting effect of the support platform 63, the push plate 65 moves vertically upward and enters the locking hole 58 of the push column 57. At this time, rotate the rotary ring 61 again to make the rotary ring 61 block the upward-moved push plate 65. Since when the sliding buckle 56 completely locks the air vent pipe 52, the locking hole 58 of the push column 57 is exactly above the push plate 65, when the push plate 65 enters the locking hole 58, it means that the air vent pipe 52 is stably connected at this time. Since the push plate 65 restricts the movement of the push column 57, it prevents the air vent pipe 52 from falling off caused by the accidental touch and impact of the push column 57.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present invention.
