At present, it generally drives the diaphragm in the closed cavity to make bidirectional motion to generate oscillating airflow through the reciprocating motion of the motion shaft. As an effective means to artificially replace the spontaneous ventilation function, the ventilator has been widely used in respiratory management, respiratory support therapy and emergency resuscitation for respiratory failure caused by various reasons and during major surgery, and occupies a very important position in the field of modern medicine.

[0023] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0024] Please refer to Figure 1-Figure 4 , this embodiment provides a ball valve integrated module, the ball valve integrated module includes a valve body 110, a valve core 120, a transmission unit 130 and an electromagnetic drive assembly 140; The valve core 120 is rotatably disposed in the valve body 110, and the valve core 120 is transmission-connected to the electromagnetic drive assembly 140 through the transmission unit 130. The electromagnetic drive assembly 140 is used to drive the valve core 120 to rotate in the valve body 110 to adjust the flux of the valve body 110; The valve core 120 is spherical and has at least one conducting slot 121 formed on its circumference. The conducting slot 121 gradually increases in size from both ends of the conducting slot 121 to its middle, along the direction of the rotation axis 160 of the valve core 120 relative to the valve body 110 .

[0025] Please refer to Figure 1-Figure 4 , the working principle of the ball valve integrated module is: First, in this embodiment, the ball valve integrated module is applied to a high-frequency ventilator to adjust its gas flow rate, while in other embodiments of the present invention, the ball valve integrated module can also be applied to the fluid passages of other types of devices to adjust the flow rate in the fluid passages; Specifically, the ball valve integrated module adopts a spherical valve core 120 configured in the valve body 110, and the valve core 120 is rotatably arranged in the valve body 110, and the valve core 120 is driven to rotate in the valve body 110 through the arrangement of the transmission unit 130 and the electromagnetic drive component 140, so that the flux of the valve body 110 can be adjusted by the rotation of the valve core 120 in the valve body 110; The flux of the valve body 110 refers to the flow rate from the air inlet to the air outlet, which is adjusted by the rotation of the valve core 120 to adjust the size of the conduction port at the position where the valve core 120 is installed in the valve body 110; Furthermore, when configuring the valve core 120, a conducting notch is configured on the circumference of the valve core 120. The function of the conducting notch 121 is to conduct the valve body 110. Moreover, since the sizes of the conducting notch 121 at various positions are not consistent, and the conducting notch 121 gradually increases from the two ends to the middle of the conducting notch 121 around the direction of the rotation axis 160 of the valve core 120 relative to the valve body 110, the two ends of the conducting notch 121 can be symmetrically arranged relative to the middle of the conducting notch 121, thereby making the valve core 120 When the electromagnetic drive assembly 140 rotates in the valve body 110 under the action of the aforementioned electromagnetic drive assembly 140, the valve core 120 can be turned clockwise or counterclockwise to conduct, and the air flow opening formed when rotating in different directions to the same rotation angle remains consistent, thereby improving the convenience of its operation; in addition, the conduction notch 121 is designed as an arc-shaped notch with a large middle and small ends, and then when the valve core 120 rotates clockwise or counterclockwise, the opening adjustment of the valve core 120 is first increased and then decreased, and the output air flow also first increases and then decreases; Therefore, through the above-mentioned structural setting method, the accuracy of flow regulation can be improved, thereby improving the stability of the air flow, and its structure is simple, which can reduce the cost of production and use.

[0026] For further information, please refer to Figure 1-Figure 4 In this embodiment, the valve core 120 is provided with two conducting slots 121, and the two conducting slots 121 are spaced 180° apart around the rotation axis 160 of the valve body 110. Thus, the flow rate regulation accuracy can be improved in this way, and the two are spaced 180° apart, so that the two conducting slots 121 can have a position where they can be conducted at the same time, thereby improving the conduction amount.

[0027] Based on the above content, when configuring the conductive slot 121, the actual contour can be adjusted according to actual needs, so that its two ends can have symmetrical regular arc contours, or it can be set to a slot type with the same conductivity change trend at both ends but different shapes according to usage requirements.

[0028] For further information, please refer to Figure 1-Figure 9In this embodiment, when configuring the valve core 120, in order to improve the stability of the operation of the valve core 120 and thus improve the stability of its flow regulation, the ball valve integrated module further includes a valve stem 150 and a rotating shaft 160; the valve body 110 is configured with a first connecting seat 170 and a second connecting seat 180, and the first connecting seat 170 and the second connecting seat 180 are respectively provided with a first mounting hole 171 and a second mounting hole 181, and the first mounting hole 171 and the second mounting hole 181 are coaxial; The valve stem 150 and the rotating shaft 160 are rotatably connected to the first mounting hole 171 and the second mounting hole 181 respectively, and the axes of the valve stem 150 and the rotating shaft 160 coincide with each other; the valve stem 150 extends out of the first mounting hole 171 and is in transmission connection with the transmission unit 130; The valve core 120 is keyed to the valve stem 150 and is connected to the rotating shaft 160 .

[0029] That is, based on the above-mentioned structural setting mode, the valve core 120 is rotatably set in the valve body 110 through the valve stem 150 and the rotating shaft 160. Such a setting mode enables two coaxial positions on the outer periphery of the valve core 120 to be connected to the valve body 110 as rotation connection points, thereby improving the connection stability through multi-point connection; and when the valve core 120 is rotatably connected, the valve stem 150 is connected to the valve core 120 through the connecting key 151. Such a setting mode is intended to drive the valve stem 150 to rotate, thereby driving the valve core 120 to rotate in the valve body 110; In addition, when configuring the valve body 110, the valve body 110 is configured with a first connecting seat 170 and a second connecting seat 180, and the first connecting seat 170 and the second connecting seat 180 are respectively provided with a first mounting hole 171 and a second mounting hole 181, and the first mounting hole 171 and the second mounting hole 181 are coaxial; the valve stem 150 and the rotating shaft 160 are respectively rotatably connected to the first mounting hole 171 and the second mounting hole 181, and the axes of the valve stem 150 and the rotating shaft 160 coincide; the valve stem 150 extends out of the first mounting hole 171 and is transmission-connected to the transmission unit 130; through the aforementioned structural setting, the operating stability of the valve core 120 can be improved based on the first connecting seat 170 and the second connecting seat 180 and the matching structure, and the first connecting seat 170 and the second connecting seat 180 can facilitate the setting of the sealing structure, thereby facilitating the improvement of its sealing performance.

[0030] Further, when the valve stem 150 is installed, in order to make it rotatably arranged in the first mounting hole 171, the first mounting hole 171 is provided with a first bearing 172, the first bearing 172 is sleeved on the valve stem 150, and the valve stem 150 is rotatably connected to the first mounting hole 171 through the first bearing 172; and on this basis, in order to improve the sealing performance of the first connecting seat 170, the ball valve integrated module further includes a gland 173, the gland 173 is sleeved on the valve stem 150, and a part of the gland 173 extends into the first mounting hole 171 and is spaced from the first bearing 172, and the first mounting hole 171 The area between the gland 173 and the first bearing 172 is filled with a sealing packing 174; the outer periphery of the valve stem 150 is provided with a pressing platform 152 for pressing the gland 173; thus, through such a setting, the gland 173 can be pressed by the pressing platform 152 on the outer periphery of the valve stem 150, thereby keeping a portion of the gland 173 extending into the first mounting hole 171, and in this way, the sealing packing 174 between the gland 173 and the first bearing 172 can stably maintain its position in the first mounting hole 171, thereby improving the sealing performance of the first connecting seat 170; When installing the rotating shaft 160, a second bearing 182 is arranged in the second mounting hole 181, and the rotating shaft 160 is rotatably connected to the second mounting hole 181 through the second bearing 182, thereby improving the rotation stability of the rotating shaft 160; and in order to improve the sealing performance of the second connecting seat 180, the second connecting seat 180 is connected to a valve cover 184 that closes the second mounting hole 181, so as to close the second mounting hole 181. On this basis, a sealing ring 183 may be arranged between the second bearing 182 and the rotating shaft 160, and a gasket 185 may be arranged between the second bearing 182 and the valve cover 184. Therefore, through the aforementioned structural arrangement, the rotation stability of the rotating rod and the sealing performance of the second connecting seat 180 are improved.

[0031] In summary, it can be seen from the above content that the ball valve integrated module can improve the stability of the valve core 120 in the valve body 110 through the above structural setting, thereby improving the stability during the flow regulation process. On this basis, in order to improve the rotation accuracy of the valve core 120 and simplify its driving structure, please refer to Figure 1-Figure 10 , the transmission unit 130 may include a transmission box 131 and a crank-connecting rod mechanism 132; The transmission box 131 is connected to the valve body 110; the crank connecting rod mechanism 132 is placed in the transmission box 131, and the crank connecting rod mechanism 132 is transmission-connected to the electromagnetic drive assembly 140; The valve stem 150 extends into the transmission box 131 and is transmission-connected to the crank-connecting rod mechanism 132 .

[0032] Thus, through the above-mentioned setting, the linear motion of the electromagnetic drive assembly 140 can be converted into the rotation of the driving valve stem 150 through the crank connecting rod mechanism 132 in the transmission box 131. Specifically, the crank connecting rod mechanism 132 includes a transmission rod 133, a crank 134 and a connecting rod 135; The transmission rod 133 is rotatably connected to the transmission box 131, and the transmission rod 133 is connected to the valve stem 150 extending into the transmission box 131, and the rotation axis 160 line of the transmission rod 133 coincides with the rotation axis 160 line of the valve stem 150; The two ends of the crank 134 are respectively connected to the transmission rod 133 and the connecting rod 135, and the connecting rod 135 is in transmission connection with the electromagnetic driving assembly 140; The connection between the transmission rod 133 and the crank 134 is spaced apart from the connection between the transmission rod 133 and the valve stem 150 .

[0033] Therefore, when the electromagnetic drive component 140 drives the connecting rod 135 to move linearly, since the two ends of the crank 134 are respectively connected to the transmission rod 133 and the connecting rod 135, and the connection between the transmission rod 133 and the crank 134 is spaced relative to the connection between the transmission rod 133 and the valve stem 150, that is, the position on the transmission rod 133 connected to the valve stem 150 and the position connected to the crank 134 are eccentrically arranged, so that the linear motion of the connecting rod 135 can drive the valve stem 150 to rotate through the transmission of the crank 134. Such a setting can simplify its transmission structure and improve its transmission accuracy and flow connection accuracy.

[0034] When configuring battery-powered components, please refer to Figure 1-Figure 11 , the electromagnetic drive assembly 140 includes a drive housing 141, an electromagnetic unit, a piston 142 and a transmission shaft 143; The electromagnetic unit is accommodated in the driving housing 141, and the piston 142 is slidably disposed in the driving housing 141; the electromagnetic unit is used to magnetically actuate the piston 142 to slide in the driving housing 141; One end of the transmission shaft 143 is connected to the piston 142 , and the other end of the transmission shaft 143 extends into the transmission box 131 and is transmission-connected to the connecting rod 135 .

[0035] That is, in this embodiment, the magnetic action of the electromagnetic unit is used to drive the piston 142 to slide in the drive housing 141, thereby driving the transmission shaft 143 to move relative to the drive housing 141, and the transmission shaft 143 is connected to the piston 142 while being connected to the connecting rod 135 in the transmission box 131. Through such a connection, linear motion can be generated and transmitted to the transmission box 131, thereby acting on the valve stem 150, causing the valve stem 150 to rotate.

[0036] It should be noted that, in this embodiment, along the sliding direction of the piston 142, the electromagnetic unit and the transmission shaft 143 are located at both ends of the piston 142, and the electromagnetic unit includes a coil 144 and an iron core 145, the coil 144 is connected to the driving housing 141, and the coil 144 is sleeved on the iron core 145; The electromagnetic drive assembly 140 further includes an elastic member 146 , which is sleeved on the transmission shaft 143 and is used to abut against the piston 142 ; The coil 144 is used to electromagnetically act on the iron core 145 so that the iron core 145 moves toward the piston 142 and squeezes the elastic member 146 ; the elastic member 146 is used to make the piston 142 have a tendency to move toward the direction of the coil 144 .

[0037] That is, in this embodiment, the electromagnetic field generated by the power supply of the battery unit can make the iron core 145 move in the driving housing 141, and then make it move in the direction of the piston 142, so that when it moves in the same direction to the position of abutting against the piston 142, it can drive the piston 142 to overcome the elastic force of the elastic member 146 and drive the transmission shaft 143 to continue to move in the same direction. In this process, the movement amount of the iron core 145 can be adjusted by controlling the power supply of the coil 144; and after the power supply state of the coil 144 is canceled, the compressed elastic member 146 is compressed. The elastic member 146 can act on the piston 142, so that the piston 142 can move toward the direction of the coil 144 under the elastic action of the elastic member 146; thereby, the movement of the piston 142 in two directions can be realized; it should be noted that, in other embodiments of the present invention, when the piston 142 is driven to move linearly in the drive housing 141 by the magnetic action of the electromagnetic unit, the piston 142 can be set as a metal part or a component that can move under the magnetic action, so that the piston 142 can sense the magnetic changes of the electromagnetic unit and realize movement.

[0038] Furthermore, in this embodiment, the electromagnetic drive assembly 140 further includes an elastic pad 147, a third bearing 148 and a shaft seal 149; The elastic pad 147 is connected to the drive housing 141 and is located on the side of the piston 142 away from the iron core 145, and is used to resist the piston 142; the third bearing 148 is connected to the drive housing 141, and the third bearing 148 is sleeved on the transmission shaft 143, and the shaft seal 149 is arranged on the side of the third bearing 148 away from the piston 142.

[0039] By setting the elastic pad 147, the impact force between the piston 142 and the drive housing can be reduced, thereby reducing operating noise and operating wear. In addition, by setting the third bearing 148, the operating stability of the transmission shaft 143 can be improved, and by setting the shaft seal 149, its sealing performance can be improved.

[0040] Based on the above, please refer to Figure 1-Figure 11 The working steps of the ball valve integrated module are as follows: When in use, after the valve body 110 and the electromagnetic drive assembly 140 are positioned and installed, the relative positions of the two remain unchanged, and then the electromagnetic drive assembly 140 can perform subsequent work after driving the transmission shaft 143 to move. Specifically, the coil 144 is energized so that the iron core 145 abuts against the piston 142, thereby pushing the piston 142 and the transmission shaft 143 to move toward the outside of the driving housing 141 and compressing the elastic member 146; Subsequently, after the movement of the transmission shaft 143 is transmitted to the transmission unit 130, the transmission shaft 143 drives the connecting rod 135 to move linearly in the same direction of the transmission shaft 143, and the movement of the connecting rod 135 can drive the transmission rod 133 to rotate through the crank 134, so that in the transmission process, the linear movement output by the electromagnetic drive unit acts on the valve stem 150, which can drive the valve stem 150 to rotate, and the rotation of the valve stem 150 can drive the valve core 120 to rotate in the valve body 110, so as to adjust the position of the conduction slot 121 thereof, thereby changing the conduction state of the air inlet and the air outlet of the valve body 110, and adjusting the conduction flow rate thereof at the same time; When the coil 144 is powered off, the magnetic effect of the iron core 145 disappears. At this time, the driving effect of the iron core 145 on the piston 142 disappears, and the elastic member 146 of the elastic member 146 can drive the piston 142 and the iron core 145 to move toward the direction of the coil 144, thereby driving the transmission shaft 143 to shrink into the driving housing 141. At the same time, the movement of the transmission shaft 143 can also be transmitted to the valve stem 150 through the transmission unit 130. The driving principle is the same as the above content, so it is not repeated here. In this way, the position of the valve core 120 is adjusted. When the valve core 120 rotates to the initial position, the air inlet and the air outlet of the valve body 110 can be blocked. Therefore, through the above content, the conduction state and conduction amount of the valve body 110 can be adjusted by controlling the power supply of the coil 144. Specifically, by setting different conduction currents, the iron core 145 will generate different thrusts. When the iron core 145 pushes the piston 142, the piston 142 further compresses the elastic part 146. Different thrusts will cause the transmission shaft 143 to move different distances, thereby controlling the change in the rotation angle of the valve core 120. Different rotation angles of the valve core 120 will cause the opening of the air inlet of the valve body 110 to be different, thereby realizing the adjustment of the air flow in the air path.

[0041] Based on the above-mentioned valve stem 150 and rotating shaft and related structural settings, the stability of the movement of the valve core 120 when it is driven to move relative to the valve body 110 can be improved; and based on the above-mentioned electromagnetic drive component 140 and the transmission unit 130 settings, the accuracy of the rotation control of the valve core 120 can be improved, thereby improving the accuracy of flow control and the stability of the flow regulation process; and through the valve cover 184, the pressure cover 173, the sealing packing 174 and related supporting structures, the sealing of the module during operation can be improved, which is beneficial to extending its service life.

[0042] Based on the above, please refer to Figure 1-Figure 11 This embodiment also provides a high-frequency ventilator, which includes an air circuit and the above-mentioned ball valve integrated module. The valve body 110 of the ball valve integrated module is connected to the air circuit and is used to adjust the flow in the air circuit.

[0043] The high-frequency ventilator can improve the accuracy of flow regulation and thus improve the stability of its air flow by adopting the above-mentioned ball valve integrated module. It also has a simple structure and can reduce the cost of production and use.

[0044] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
