For example, a cooling device may be connected to the bottom of the barrel body 202 to cool the barrel body 202. The purpose of this setting is to increase the temperature difference in this way, thereby accelerating the condensation of respiratory gases.

[0018] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, they are not limited to the specific skateboard 201 described in the above embodiments. For example, a damping rubber strip is provided at the connection between the skateboard 201 and the shell 101. The purpose of this setting is to increase the damping of the connection in this way and prevent noise during sliding.

[0019] Specifically, a connecting pipe 204 is fixedly connected to the top of the barrel body 202 , and the two connecting pipes 204 are threadedly connected to a screw barrel 205 via threaded rings thereon, and the screw barrel 205 is rotatably connected to the air pipe 206 .

[0020] For the above example, those skilled in the art should be aware that when implementing the above technical solution, they are not limited to the specific connecting tube 204 described in the above embodiment. For example, a gasket is provided in the connecting tube 204. The purpose of this setting is to facilitate the air pipe 206 to be tightly connected to the connecting tube 204 when it is inserted into the connecting tube 204 through the gasket.

[0021] Specifically, a plug 207 is slidably connected in the cavity of the slide plate 201 , a plug hole is provided on the slide plate 201 at a position corresponding to the plug 207 , and a plurality of plug holes are provided on the housing 101 .

[0022] For the above example, those skilled in the art should be aware that when implementing the above technical solution, they are not limited to the specific plug 207 described in the above embodiment. For example, the plug 207 is wrapped with a rubber ring. The purpose of this arrangement is to facilitate the insertion of the plug 207 into the skateboard 201 in this way, thereby reducing the gap at the connection and preventing the barrel body 202 from shaking.

[0023] Specifically, the plug 207 is fixedly connected to the spring 208 via a pad thereon, and the other end of the spring 208 is fixedly connected to the slide plate 201 .

[0024] For the above examples, those skilled in the art should be aware that when implementing the above technical solution, they are not limited to the specific spring 208 described in the above embodiment. For example, the spring 208 can be replaced with other forms of elastic materials. The purpose of this setting is that the spring is prone to deformation after long-term use, thereby losing its elasticity. By replacing it with a material that is not easily deformed, its service life can be effectively extended.

[0025] Specifically, a pull ring 209 is fixedly connected to the spring 208 , and the pull ring 209 is slidably connected to the slide plate 201 .

[0026] For the above examples, those skilled in the art should know that when implementing the above technical solution, they are not limited to the specific pull ring 209 described in the above embodiment. For example, the pull ring 209 can be configured to be folded downward.

[0027] Specifically, a left-hand screw rod 301 is rotatably connected in the cavity at the upper end of the shell 101 , the other end of the left-hand screw rod 301 is fixedly connected to a right-hand screw rod 302 , the right-hand screw rod 302 is rotatably connected to the shell 101 , and a dial 305 is fixedly connected to the left-hand screw rod 301 .

[0028] For the above examples, those skilled in the art should be aware that when implementing the above technical solution, they are not limited to the specific left-handed screw 301 and the right-handed screw 302 described in the above embodiments. For example, the left-handed screw 301 and the right-handed screw 302 can be replaced with a reciprocating screw. The purpose of this arrangement is that when the slide 303 threadedly connected thereto moves to one end, the movement direction of the slide 303 can be quickly changed by continuing to control the left-handed screw 301 to rotate in the same direction.

[0029] Specifically, the left-handed screw rod 301 and the right-handed screw rod 302 are respectively threadedly connected with a slide cylinder 303 , the two slide cylinders 303 are slidably connected to the housing 101 , and the two slide cylinders 303 are respectively fixedly connected with an arc plate 304 .

[0030] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, they are not limited to the specific arc plates 304 described in the above embodiments. For example, the arc plates 304 are provided with anti-slip patches. The purpose of this setting is to prevent the two arc plates 304 from sliding when clamping the bed rods.

[0031] In the embodiment of the utility model, the relevant technicians connect the two screw barrels 205 to the threaded rings of the connecting pipe 204 respectively, and rotate them manually, so that the air pipe 206 is inserted into the connecting pipe 204. At this time, the relevant technicians place the shell 101 on the bed frame and rotate the dial 305 at the same time, so that the dial 305 drives the left-hand screw rod 301 fixedly connected thereto to start rotating, so that the left-hand screw rod 301 drives the right-hand screw rod 302 fixedly connected thereto to rotate synchronously, so that the slide barrel 303 threadedly connected on the left-hand screw rod 301 and the right-hand screw rod 302 starts to move linearly along the slide rail at the connection between it and the shell 101, so that the two slide barrels 303 drive the arc plates 304 fixedly connected thereto to start linearly moving towards each other, so that the two arc plates 30 4 cooperate with each other to clamp the bed frame, thereby fixing it. At this time, the relevant technicians adjust the position of the barrel body 202 according to the position of the bed body and the respirator. First, pull the pull ring 209 horizontally, so that the pull ring 209 drives the plug 207 fixedly connected thereto to move synchronously, so that the plug 207 shrinks into the cavity of the slide plate 201, and at the same time begins to compress the pull ring 209 fixedly connected thereto. When the barrel body 202 is adjusted to make the air pipes 206 connected thereto tilt toward it, stop pulling the pull ring 209, so that the spring 208 starts to rebound and reset, thereby pushing the plug 207 fixedly connected thereto, so that the plug 207 is inserted into the groove on the slide plate 201, so as to achieve the fixed position of the barrel body 202, so that the condensed liquid flows into the barrel body 202 to prevent it from flowing back.

[0032] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0033] The fixed connection referred to in this application refers to a connection in which a part or component is fixed without any relative movement, which can be divided into detachable connection and non-detachable connection.
