Description

Technical Field

[0001] The present invention belongs to the technical field of medical equipment, and in particular relates to a ventilator structure. Background Art

[0002] A ventilator is a device that can replace, control or change a person's normal physiological breathing process. It aims to increase lung ventilation, improve respiratory function, reduce the energy consumption required for breathing, and save heart reserve capacity.

[0003] With the advancement of medical technology, ventilators are becoming increasingly versatile. The rise of smart medical technology has boosted the data collection and connectivity capabilities of ventilators. By installing various interfaces on ventilators, real-time upload of patient monitoring data is possible. This allows medical staff to monitor the patient's health status in real time. Furthermore, continuous monitoring of the ventilator, combined with various sensors installed on the ventilator (such as temperature sensors, pressure sensors, and various gas flow meters), further enhances ventilator safety.

[0004] The multifunctional nature of ventilators results in a very compact internal space. High-heat-generating components like the power supply and motherboard, along with the ventilation components, are centrally located within the ventilator. When the ventilator is operating, the electronic components on the power supply and motherboard generate concentrated heat, which in turn radiates heat to each other, easily leading to abnormal temperatures within the ventilator. Although most ventilators incorporate internal fans for heat dissipation, the limited size of the device and the influence of the ventilation components result in a cluttered heat dissipation path and poor heat dissipation. Failure to promptly manage this heat can affect the ventilator's performance and, in the long term, shorten its lifespan. Summary of the Invention

[0005] The purpose of the present invention is to provide a ventilator structure that can not only achieve miniaturization of the ventilator, but also dissipate heat in time from the internal circuit assembly board of the ventilator, thereby avoiding local excessive temperature affecting the normal use of the ventilator and prolonging the life of the ventilator.

[0034] See also Figures 1 to 5 A ventilator structure includes: a shell 1, a circuit structure 2 and a ventilation component 3.

[0035] The shell 1 is provided with an upper mounting cavity 11 and a lower mounting cavity 12 separated from each other, and a gas circulation channel is provided between the upper mounting cavity 11 and the lower mounting cavity 12 and between the shell 1 and the outside world. The circuit structure 2 includes a power module 21, a mainboard control module 22 and a plurality of auxiliary function modules. The power module 21 is installed in the lower mounting cavity 12, and the mainboard control module 22 and the auxiliary function modules are installed in the upper mounting cavity 11. At least one auxiliary function module is arranged at a prefabricated angle with the mainboard control module 22. The ventilation component 3 is installed below the mainboard control module 22, and at least part of the ventilation component 3 is installed along the circumferential inner wall of the upper mounting cavity 11. Specifically, the shell 1 is provided with a partition plate 14, which divides the shell 1 into an upper mounting cavity 11 and a lower mounting cavity 12. The upper mounting cavity 11 and the lower mounting cavity 12 are respectively provided with a plurality of grooves 15 of different depths for installing components of different heights. The grooves are separated by retaining ribs, such as the high-pressure proportional valve groove, the turbine fan groove, etc. The housing 1 is sequentially provided with a mainboard control module 22, a ventilation assembly 3, a partition plate 14, and a power module 21 from top to bottom. Each component is installed in order in the housing 1 and is installed between each circuit module and the ventilation assembly 3. Preferably, the housing 1, the retaining rib, and the partition plate 14 are integrally formed. After assembly, the ventilator has an external dimension of 319mm×223mm×185mm. The main heat-generating electronic components of the power module 21 are installed on the substrate facing away from the partition plate 14, while the main heat-generating electronic components of the mainboard control module 22 are installed on the substrate facing the partition plate 14.

[0036] The partition plate 14 divides the chamber of the shell 1 into an upper mounting chamber 11 and a lower mounting chamber 12, and the circuit modules of the ventilator are respectively installed in the upper mounting chamber 11 and the lower mounting chamber 12 in a three-dimensional manner. The ventilation component 3 is arranged below the mainboard control module 22 and part of the ventilation component 3 is installed on the side of the upper mounting chamber 11. This can not only optimize the structural layout inside the shell 1, so that the arrangement of each component occupies less space, which contributes to the overall miniaturization design of the ventilator, but also the power module 21, the mainboard control module 22, and the auxiliary function module ventilation component 3 are distributed in different three-dimensional spatial positions, not a simple stacked layout. The ventilation component 3 does not hinder the heat dissipation channel, leaving enough heat dissipation space and a smooth heat dissipation channel, reducing the radiation heat transfer and timely heat transfer between each circuit module when working. A gas circulation channel is provided between the upper mounting chamber 11 and the lower mounting chamber 12 and between the shell 1 and the outside world, which transfers the heat in the chamber of the shell 1 to the outside of the shell, avoiding local excessive temperature affecting the normal use of the ventilator and improving the life of the ventilator.

[0037] See also Figure 4 and Figure 6 Furthermore, a first support column 111 is provided in the upper mounting cavity 11, and the mainboard control module 22 is mounted on the first support column 111. Specifically, a plurality of first support columns 111 of equal height are provided on the upper surface of the partition plate 14. The number and position of the first support columns 111 coordinate with the positioning holes of the circuit substrate of the mainboard control module 22. By maintaining a certain distance between the first support columns 111 and the partition plate 14, not only does this create a space for the heat dissipation flow channel of the mainboard control module 22, but it also facilitates the installation of the ventilation assembly 3 within the space.

[0038] See also Figure 4 Furthermore, the upper mounting cavity 11 is provided with a second support column 112 that is lower than the first support column 111. The second support columns 112 have different heights, and each branch of the ventilation component 3 is respectively installed on the second support column 112. The mounting cavity 11 is provided with multiple second support columns 112, and the ventilation component 3 can be raised or lowered as needed, which is convenient for layered three-dimensional layout with each circuit module. A certain gap is left between the highest point of the ventilation component 3 and the mainboard control module 22, thereby facilitating smooth gas flow and miniaturizing the ventilator as a whole.

[0039] See also Figure 1 、 Figure 2 and Figure 5Furthermore, the circuit structure 2 also includes a USB interface 23, a communication interface 24 and a power input interface 25 arranged on the side wall of the shell 1, and matching sockets are provided on the power module 21 and the mainboard control module 22. The USB interface 23, the communication interface 24 and the power input interface 25 are respectively connected to the corresponding sockets with a transfer line 26. Specifically, the side wall of the shell 1 is provided with a plurality of interface mounting holes 17 that pass through the side wall. The USB interface 23, the communication interface 24 and the power input interface 25 are respectively installed in the corresponding interface mounting holes 17, which is convenient for connection with external equipment. By setting various interfaces and setting corresponding sockets on the power module 21 or the mainboard control module 22, instead of directly laying out the conventional interfaces on the circuit substrate, the area of ​​the circuit substrate can be reduced, thereby contributing to the overall miniaturization design of the ventilator. Moreover, the circuit substrate is small, and there is a gap between the side walls around the circuit substrate and the inner wall of the shell, which can leave more heat dissipation space in the upper mounting cavity 11 or the lower mounting cavity 12.

[0040] See also Figure 1 and Figure 3 Furthermore, the housing 1 also includes a display screen side cover 18, and the auxiliary function module includes a display screen circuit module 27. The display screen circuit module 27 is installed on the inner wall of the display screen side cover 18, and the display screen 4 is installed on the outer side 18 of the display screen side cover. The display screen circuit module 27 and the main board control module 22 are set at a prefabricated angle. Specifically, the display screen side cover 18 is installed on the outside of the housing 11 at a prefabricated angle. A third support column 181 is provided on the inner wall of the display screen side cover 18. The number and position of the third support column 181 are used in conjunction with the substrate positioning hole of the display screen circuit module 27. By utilizing the third support column 181, there is a gap between the display screen circuit module 27 and the display screen side cover 18, which helps to dissipate heat from the electronic components on the display screen circuit module 27. The main control module 22 and the display screen circuit module 27 are set at a prefabricated angle and installed in a three-dimensional manner, which not only helps to dissipate heat from the display screen circuit module 27 and the display screen 4 when working, but also saves installation space, thereby contributing to the overall miniaturization of the ventilator.

[0041] See also Figure 1 and Figure 3 Furthermore, the display side cover 18 is provided with an extension 182. The auxiliary function module also includes an indicator circuit module 28, which is mounted on the inner wall of the extension 182. The indicator circuit module 28 is arranged at a prefabricated angle with the display circuit module 27. Specifically, the housing 1 is also provided with an upper cover 19. The extension 182 extends upward from the upper cover 19. The installation space of the upper cover 19 is utilized to reduce the longitudinal space for installing the indicator circuit module 28, thereby contributing to the overall miniaturization of the ventilator and providing sufficient heat dissipation space for the indicator circuit module 28.

[0042] See also Figure 6Furthermore, the ventilation component 3 includes an oxygen supply branch 31, an air supply branch 32, an air-oxygen mixing pipe 33 and an air-oxygen output branch 34. The ventilation component 3 is E-shaped in appearance. The oxygen supply branch 31 and the air supply branch 32 are connected to one end of the air-oxygen mixing pipe 33, and one end of the air-oxygen output branch 34 is connected to the air-oxygen mixing pipe 33. The air supply branch 32, the air-oxygen mixing pipe 33 and the air-oxygen output branch 34 are installed along the circumferential inner wall of the upper mounting cavity 11. Specifically, the ventilation component 3 is installed on the second support column 112, the oxygen supply branch 31 and the air-oxygen output branch 34 are installed directly below the mainboard control module 22, and the air supply branch 32 and the air-oxygen mixing pipe 33 are installed along the circumferential inner wall of the upper mounting cavity 11. With this structure, the various components of the ventilation component 3 are installed in the upper mounting cavity 11 in an orderly manner, which is conducive to the smooth heat dissipation flow channel in the upper mounting cavity 11. The oxygen supply branch 31 includes a high-pressure proportional valve 311, a first flowmeter 312, and an oxygen duct 313. The high-pressure proportional valve 311 is connected to an external oxygen supply device to control the proportion of oxygen entering. The first flowmeter 312 is installed in the oxygen duct 313. The air supply branch 32 includes a turbine blower 321, an air duct 322, and a second flowmeter 323. The turbine blower 321 has an air inlet. The second flowmeter 323 is connected to the turbine blower 321 at one end and to the air duct 322 at the other. The air-oxygen mixing duct 33 is connected to the oxygen duct 313 and the air duct 322 at one end, respectively, and to the air-oxygen output branch 34 at the other end. The oxygen supply branch 31 and the air supply branch 32 are independently configured, allowing for independent buffering, adjustment, and parameter monitoring. This allows personnel to precisely adjust the oxygen flow rate of the oxygen supply branch and the air flow rate of the air supply branch, thereby achieving precise control of the output flow rate and oxygen concentration. Replacing a conventional air-oxygen mixer with the air-oxygen mixing tube 33 not only saves material costs but also reduces the size of the ventilator. Preferably, the tube of the ventilation assembly 3 is made of a plastic material with good thermal conductivity. When each circuit module is operating, some of the heat generated by the electronic components is transferred to the tube of the ventilation assembly 3 and dissipated with the airflow in the tube, thus providing auxiliary heat dissipation.

[0043] See also Figure 4 and Figure 6 , further, it also includes a fan 5, which is installed in the upper installation cavity 11; a first ventilation groove 16 that cooperates with the fan 5 is provided on one side of the shell 1. Specifically, a fan 5 is provided in the ventilator, and a sinking groove 113 connected to the first ventilation groove 16 is provided in the upper installation cavity 11, and the fan is installed in the sinking groove 113. When working, using the principle of air flow, the fan 5 draws the outside air from the first ventilation groove 16 into the inside of the fan 5, and after being accelerated and turned by the fan 5, the cold air is discharged, and the gas with a relatively high temperature inside the ventilator is discharged, so that the shell can achieve the effect of ventilation.

[0044] See also Figure 4 and Figure 5 Furthermore, the sidewall of the partition plate 14 is circumferentially provided with two or more groups of second ventilation slots 141, with at least one group of second ventilation slots 141 positioned opposite the first ventilation slots 16. A third ventilation slot 142 runs through the surface of the partition plate 14. To further accelerate airflow between the upper mounting chamber 11 and the lower mounting chamber 12, the sidewall of the partition plate 14 is circumferentially provided with multiple groups of second ventilation slots 141, with at least one group of second ventilation slots 141 positioned opposite the first ventilation slots 16. This allows the cooling airflow from the fan 5 to flow simultaneously into the upper mounting chamber 11 and the lower mounting chamber 12.

[0045] See also Figure 7 Furthermore, the housing 1 further includes a lower cover 13, which is provided with a fourth ventilation groove 131. Part of the heat of the lower mounting cavity 12 is directly discharged from the fourth ventilation groove 131, further improving the heat dissipation effect.

[0046] In the above-mentioned ventilator structure, the partition plate 14 divides the housing 1 chamber into an upper mounting chamber 11 and a lower mounting chamber 12, and the various circuit modules of the ventilator are respectively installed in the upper mounting chamber 11 and the lower mounting chamber 12 in a three-dimensional manner, and a first support column 111 and a second support column 112 of different heights are provided. The ventilation component 3 is provided below the mainboard control module 22, which can not only optimize the structural layout inside the housing 1 and ensure the smooth flow of gas. The power module 21, the mainboard control module 22 and the auxiliary function module are distributed in different three-dimensional spatial positions, not a simple stacked layout; various interfaces are provided and corresponding sockets are provided on the power module 21 or the mainboard control module 22, instead of the conventional interfaces being directly arranged on the circuit substrate, which can reduce the area of ​​the circuit substrate, thereby not only contributing to the miniaturization of the ventilator as a whole, but also providing enough heat dissipation space to reduce the radiation heat transfer between each other during operation. A second ventilation groove 141 and a third ventilation groove 142 are provided to allow air to flow between the upper mounting cavity 11 and the lower mounting cavity 12 to form a gas circulation channel. A fourth ventilation groove 131 and a first ventilation groove 16 are provided to form a gas circulation channel between the inner cavity of the shell 1 and the outside. The fan 5 is then used to discharge the gas with relatively high temperature in the upper mounting cavity 11 and the lower mounting cavity 12 out of the ventilator, so that the circuit assembly board of the ventilator has good heat dissipation, avoids local excessive temperature affecting the normal use of the ventilator, and improves the life of the ventilator.

[0047] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above is only a specific implementation method of the present invention and is not intended to limit the present invention.
