Abstract
Description
Technical Field
[0001] This utility model relates to the field of ventilator technology, and more specifically, to a ball valve integrated module and a high-frequency ventilator. Background Technology
[0002] As an effective means of artificially replacing spontaneous ventilation, ventilators are widely used in respiratory failure caused by various reasons, as well as in anesthetic respiratory management, respiratory support therapy, and emergency resuscitation during major surgeries, and occupy a very important position in the field of modern medicine.
[0003] The high-frequency device is the core component of a high-frequency ventilator and a key device for achieving high-frequency oscillating airflow. Currently, it is generally generated by the reciprocating motion of a shaft, which drives the diaphragm within a sealed cavity to move bidirectionally. However, in existing technologies, proportional valves are typically used to control the ventilator's airflow. However, proportional valves are often expensive and can easily disturb the oscillating airflow, thus affecting the stability of the airflow. Furthermore, current high-frequency ventilators use a rotating disc to control the flow rate in the airway, which can lead to unstable airflow regulation. Utility Model Content
[0004] The purpose of this invention is to provide a ball valve integrated module and a high-frequency ventilator. This ball valve integrated module, applied to a high-frequency ventilator, utilizes a drive component to rotate the valve core within the flow channel, thereby controlling the rotation angle of the valve core. Different rotation angles of the valve core result in different openings of the air inlet of the valve body, thus regulating the airflow in the airway. Furthermore, the valve core is configured with two through slots. These through slots gradually increase in size from the middle to both ends of the slots, circumferentially around the rotation axis of the valve core relative to the valve body. This allows the valve core to exhibit approximately equal percentage flow characteristics during rotation, resulting in high flow regulation accuracy, low flow resistance, and a simple structure with low manufacturing and operating costs.

[0024] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.
[0025] Please refer to Figures 1-3 This embodiment provides a ball valve integrated module 200, which includes a valve body 210, a valve core 220, and a drive assembly 230. The valve body 210 is provided with a flow guide channel 211; the valve core 220 is rotatably disposed in the flow guide channel 211, and the valve core 220 is connected to the drive assembly 230 for transmission. The drive assembly 230 is used to drive the valve core 220 to rotate relative to the valve body 210 in order to adjust the flow rate of the flow guide channel 211. The valve core 220 is a hollow sphere, and at least two through slots 221 are provided on its circumference. Around the direction of the rotation axis 214 of the valve core 220 relative to the valve body 210, the through slots 221 gradually increase in size from the middle to both ends.
[0026] Please refer to Figures 1-3 The working principle of the ball valve integrated module 200 is as follows: The ball valve integrated module 200 is used in a high-frequency ventilator. It uses a drive component 230 to drive the valve core 220 to rotate within the flow channel 211, thereby controlling the rotation angle of the valve core 220. Different rotation angles of the valve core 220 result in different openings of the air inlet of the valve body 210, thus regulating the airflow in the airway. Furthermore, when configuring the valve core 220, two through slots 221 are opened on the valve core 220. The two through slots 221 gradually increase in size from the middle to both ends of the through slots 221 around the rotation axis 214 of the valve core 220 relative to the valve body 210. This allows the valve core 220 to have an approximately equal percentage flow characteristic during rotation, resulting in high flow regulation accuracy, low flow resistance, and a simple structure with low manufacturing and operating costs.
[0027] Further, please refer to Figures 1-4 In this embodiment, when the drive assembly 230 is configured, its function is to drive the valve core 220 to rotate in the guide channel 211. Based on this, the drive assembly 230 may include a transmission box 240, a transmission rod 231, a transmission gear 232, a transmission rack 233, and a drive unit 250. The transmission housing 240 is connected to the valve body 210; one end of the transmission rod 231 extends into the flow channel 211 and is connected to the valve core 220, and the other end extends into the transmission housing 240 and is rotatably connected to the transmission housing 240; the transmission gear 232 is disposed in the transmission housing 240 and is connected to the transmission rod 231; the transmission rack 233 is connected to the drive unit 250, and a portion of the transmission rack 233 extends into the transmission housing 240 and meshes with the transmission gear 232; The transmission rack 233 moves along the tangential direction of the transmission gear 232 under the driving action of the drive unit 250.
[0028] Thus, through the above structural arrangement, the transmission rack 233 can be driven to move along the tangential direction of the transmission gear 232 under the driving action of the drive unit 250, and its movement is linear. Therefore, when the drive unit 250 is configured, the drive unit 250 is a linear drive module. When the transmission rack 233 moves along the tangential direction of the transmission gear 232, it meshes with the transmission gear 232, thereby driving the transmission gear 232 and the transmission rod 231 connected to the transmission gear 232 to rotate. Since the transmission rod 231 is connected to the valve core 220, when the transmission rack 233 drives the transmission rod 231 to rotate, it can drive the valve core 220 to rotate in the guide channel 211. Thus, by driving the valve core 220 to rotate in the guide channel 211, the rotation angle of the valve core 220 can be controlled.
[0029] With the above-mentioned structural configuration of the drive component 230, the drive unit 250 can be driven by a rack and pinion meshing method. Moreover, based on the meshing of the transmission rack 233 and the transmission gear 232, the transmission accuracy can be improved, that is, the accuracy of angle control can be improved when the drive valve core 220 rotates in the guide channel 211.
[0030] Please refer to Figures 1-5 When configuring the transmission box 240, the transmission box 240 may include a base plate 241, a box cover 242, a positioning plate 243, and a guide frame 244. The base plate 241 is connected to the valve body 210, the box cover 242 is closed on the base plate 241, and the box cover 242 has a through hole 245 for the transmission rack 233 to pass through. Thus, an independent transmission space can be formed, which can meet the movement requirements of the transmission rack 233, thereby improving the sealing of the transmission box 240. The positioning plate 243 is connected to the base plate 241, the guide frame 244 is connected to the positioning plate 243, and the part of the transmission rack 233 extending into the transmission box 240 is slidably connected to the guide frame 244. Thus, the guide frame 244 can guide the movement of the transmission rack 233.
[0031] Further, please refer to Figures 1-7 As can be seen from the foregoing, the ball valve integrated module 200 can be used in high-frequency ventilators. Under these conditions, in order to adapt to the internal structure of the high-frequency ventilator, the position of the drive component 230 relative to the valve body 210 needs to be adjusted according to requirements to meet different installation needs, thereby facilitating adaptation to high-frequency ventilators with different parameters. Specifically, there are multiple ways to adjust the position of the drive component 230 relative to the valve body 210. Some of these structural settings are described below. First, the transmission box 240 can be rotatably connected to the valve body 210 around the axis of the transmission rod 231. With this arrangement, the drive assembly 230 can be adjusted to a certain position on the valve body 210 by rotating the transmission box 240 relative to the valve body 210 to meet the installation requirements of the high-frequency ventilator.
[0032] In addition, based on the structure of the transmission box 240 mentioned above, a rotating disk 246 and other structures can be added. Specifically, the transmission box 240 includes a base plate 241, a box cover 242, a positioning plate 243, a guide frame 244, a rotating disk 246, and fixing components. The base plate 241 is connected to the valve body 210; the rotating disk 246 is rotatably connected to the base plate 241, and the rotation axis 214 of the rotating disk 246 relative to the base plate 241 coincides with the axis of the transmission rod 231; the cover 242 covers the rotating disk 246, and the cover 242 has a through hole 245 for the transmission rack 233 to pass through; the positioning plate 243 is connected to the rotating disk 246, the guide frame 244 is connected to the positioning plate 243, and the portion of the transmission rack 233 extending into the transmission box 240 is slidably connected to the guide frame 244; the fixing member is connected to the rotating disk 246 and the base plate 241, and is used to limit the rotation of the rotating disk 246 relative to the base plate 241.
[0033] Therefore, by setting a rotating disk 246 on the base plate 241 of the transmission box 240, and connecting the guide frame 244 for guiding and mounting the transmission rack 233 to the rotating disk 246, the position of the transmission rack 233 relative to the valve body 210 can be adjusted by the rotating disk 246 during use. After adjusting to the appropriate position, the subsequent drive unit 250 and the box cover 242 can be installed. Moreover, after the rotating disk 246 is rotated to the appropriate position, the fixing parts need to be installed. In this way, the position of the rotating disk 246 is specified to avoid rotational deviation during use, which would affect its use.
[0034] It should be noted that, based on the above-mentioned configuration of the rotating disk 246, in order to facilitate the installation and use of the transmission box 240, the base plate 241 can be a circular plate, and the box cover 242 can be a cylindrical box cover 242. Thus, after the box cover 242 is connected to the base plate 241, a cylindrical inner cavity can be formed. In this way, the rotating disk 246 can be rotated to any angle without affecting the connection between the box cover 242 and the base plate 241.
[0035] As can be seen from the above, when configuring the drive unit 250, it adopts a linear drive module. Based on this, the drive unit 250 includes a drive cylinder or electromagnetic drive component 251, so as to drive the transmission rack 233 to move linearly through such a structural arrangement. When using a drive cylinder, its structure can adopt existing technology; Please refer to Figures 1-8 When the drive unit 250 includes an electromagnetic drive component 251, the electromagnetic drive component 251 includes a drive housing 252, an electromagnetic module 253, a piston 254, and a drive shaft 255; the electromagnetic module 253 is housed in the drive housing 252, and the piston 254 is slidably disposed in the drive housing 252; the electromagnetic module 253 is used to magnetically actuate the piston 254 to slide within the drive housing 252; one end of the drive shaft 255 is connected to the piston 254, and the other end of the drive shaft 255 extends to the outside of the drive housing 240 and is connected to the drive rack 233.
[0036] Thus, in this way, the electromagnetic module 253 magnetically actuates the piston 254 to slide within the drive box 252, thereby driving the transmission shaft 255 and the transmission rack 233 to move during the movement of the piston 254, thereby achieving the purpose of driving the transmission gear 232 and the valve core 220 to rotate.
[0037] Furthermore, when configuring the electromagnetic module 253, along the sliding direction of the piston 254, the electromagnetic module 253 and the transmission shaft 255 are located at both ends of the piston 254, and the electromagnetic module 253 includes a coil 256 and an iron core 257. The coil 256 is connected to the drive box 252, and the coil 256 is sleeved on the iron core 257. The electromagnetic drive component 251 also includes an elastic component 258, which is sleeved on the transmission shaft 255 and is used to resist the piston 254. The coil 256 is used to electromagnetically act on the iron core 257, so that the iron core 257 moves toward the piston 254 and squeezes the elastic component 258. The elastic component 258 is used to give the piston 254 a tendency to move toward the coil 256.
[0038] Based on this, when the electromagnetic module 253 is working, the iron core 257 can move toward the piston 254 and press against the elastic element 258. When the magnetic effect of the electromagnetic module 253 disappears, the elastic element 258 can make the piston 254 move toward the coil 256. That is, through the arrangement of the electromagnetic module 253 and the elastic element 258, the piston 254 can move in two opposite directions in the drive box 252, thereby realizing the control of the rotation of the valve core 220.
[0039] In configuring the drive housing 252, to prevent the internal airflow from being compressed during the movement of the piston 254 due to the closed nature of the drive housing 252, which could cause pressure changes that affect the movement of the piston 254 or increase its resistance, the drive housing 252 has two air guide holes 259. These two air guide holes 259 are spaced apart along the sliding direction of the piston 254. The purpose is to ensure that both sides of the piston 254 can communicate with the outside environment along the direction of piston 254's movement, thus maintaining the internal air pressure consistent with the external air pressure. This ensures that the air pressure on both sides of the piston 254 is the same, preventing air pressure from affecting the normal movement of the piston 254. Furthermore, this arrangement also allows the two air guide holes 259 to connect as the piston 254 moves to corresponding positions, further reducing the impact of air pressure on the piston 254's movement. It should be noted that in this embodiment, two air guide holes 259 are arranged at intervals, so that when the piston 254 and the drive box 252 form a chamber on both sides, the two air guide holes 259 are connected to one chamber respectively.
[0040] Based on the above structure, in order to avoid the piston 254 from colliding with the drive box 252 during the movement, the drive box 252 is equipped with an elastic pad 261. The elastic pad 261 is located on the side of the piston 254 away from the iron core 257 and is used to support the piston 254, thereby playing a buffering role and reducing operating noise and wear.
[0041] Further, please refer to Figures 1-9 In this embodiment, to facilitate the rotational installation of the valve core 220 and the installation of the transmission rod 231, the valve body 210 is equipped with a first mounting seat 212 and a second mounting seat 213. The transmission rod 231 is rotatably connected to the first mounting seat 212 and extends through the first mounting seat 212 into the flow guide channel 211. The second mounting seat 213 is connected to a rotating shaft 214, which extends into the flow guide channel 211 and is connected to the valve core 220. The axis of the rotating shaft 214 coincides with the axis of the transmission rod 231. That is, with this arrangement, the transmission rod 231 and the rotating shaft 214 can be installed separately using the two mounting seats, thus facilitating the installation of the valve core 220.
[0042] When installing the transmission rod 231, it is rotatably mounted on the first mounting base 212. Therefore, the first mounting base 212 has a mounting hole and a first bearing. The first bearing is sleeved on the transmission rod 231, and the transmission rod 231 is rotatably connected to the first mounting base 212 through the first bearing. Furthermore, to improve the sealing performance of the first mounting base 212, the ball valve integrated module 200 also includes a pressure cap. The pressure cap is sleeved on the transmission rod 231, and part of it extends into the mounting hole and is spaced from the first bearing. The area in the mounting hole between the pressure cap and the first bearing is filled with sealing filler. A pressure platform for holding the pressure cap is arranged on the outer periphery of the transmission rod 231. Thus, with this arrangement, the pressure platform on the outer periphery of the transmission rod 231 can hold the pressure cap, thereby keeping part of the pressure cap extending into the mounting hole. In this way, the sealing filler located between the pressure cap and the first bearing can be stably maintained in its position in the first mounting hole, thereby improving the sealing performance of the first mounting base 212. When installing the rotating shaft 214, a second bearing is installed inside the second mounting base 213, and the rotating shaft 214 is rotatably connected to the second mounting base 213 through the second bearing, thereby improving the rotational stability of the rotating shaft 214. In addition, to improve the sealing performance of the second mounting base 213, a valve cover is connected to the second mounting base 213 to seal the mounting hole of the rotating shaft 214. Furthermore, a sealing ring can be installed between the second bearing and the rotating shaft 214, and a gasket can be installed between the second bearing and the valve cover. Through the aforementioned structural settings, the rotational stability of the rotating rod and the sealing performance of the second connecting base are improved.
[0043] Please refer to Figures 1-9 Based on the above, the working steps of the ball valve integration module 200 are as follows: During installation, adjust the relative positions of the valve body 210 and the drive assembly 230, and perform positioning installation; In use, the electromagnetic module 253 drives the piston 254 to move, which in turn drives the transmission rack 233 to move, which in turn drives the transmission gear 232 and the transmission rod 231 to move, which in turn drives the valve core 220 to rotate; thereby adjusting the position of the guide slot 221 of the valve core 220, thereby changing the conduction state of the guide channel 211 of the valve body 210, and simultaneously regulating the flow rate of the channel. Specifically, during the movement of piston 254, coil 256 is energized, causing iron core 257 to abut against piston 254, thereby pushing piston 254 and drive shaft 255 to move outward from drive box 252 and compress elastic element 258. When the coil 256 is de-energized, the magnetic effect of the iron core 257 disappears. At this time, the driving force of the piston 254 on the iron core 257 disappears, while the elastic element 258 can drive the piston 254 and the iron core 257 to move towards the coil 256, thereby driving the transmission shaft 255 to retract. At the same time, the movement of the transmission shaft 255 can also be transmitted to the valve stem through the transmission rack 233. Its driving principle is the same as the above, so it will not be repeated here. In this way, the position of the valve core 220 is adjusted.
[0044] It should be noted that in this embodiment, when the valve core 220 rotates to the initial position, the flow channel 211 of the valve body 210 is blocked. Therefore, by controlling the energization of coil 256, the conduction state and flow rate of the flow channel 211 of valve body 210 can be adjusted. Specifically, by setting different conduction currents, iron core 257 will generate different thrusts. When iron core 257 pushes piston 254, piston 254 further compresses elastic element 258. Different thrusts will cause different movement distances of transmission shaft 255, thereby controlling the change of rotation angle of valve core 220. Different rotation angles of valve core 220 will cause different openings of air inlet of valve body 210, thereby achieving the adjustment of airflow in the air path.
[0045] Based on the aforementioned transmission rod 231, rotating shaft 214, and related structural arrangements, the stability of the valve core 220's movement when driven relative to the valve body 210 can be improved. Furthermore, based on the aforementioned drive assembly 230, the accuracy of valve core 220 rotation control can be improved, thereby enhancing the accuracy of flow control and the smoothness of flow regulation. Moreover, the valve cover, gland, sealing packing, and related supporting structures can improve the sealing performance of the module during operation, which is beneficial for extending its service life.
