[0037] A ventilator is a device that assists or replaces breathing, increasing lung ventilation and improving respiratory function. It is typically used for patients with lung failure or airway obstruction who cannot breathe normally. A ventilator consists of a main unit structure, which extracts air through a blower inside the main unit and then supplies it to the user through a humidifier. However, the main unit structure is typically fixed and can only be used with one type of blower or a similar blower, resulting in low adaptability.

[0038] Based on this, an embodiment of the present application provides a ventilator host structure that can adapt to fans of different shapes and sizes, thereby expanding the scope of application of the ventilator host structure. The ventilator host structure provided by an embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0039] See Figure 1 and Figure 2 , Figure 1 This is an exploded view of the ventilator host structure provided in one embodiment of the present application. Figure 2 Schematic diagram of the baffle and lower shell in the main structure of the ventilator provided by one embodiment of the present application. The main structure of the ventilator provided by one embodiment of the present application includes a shell 100, a baffle 200 and an isolating member 300; the shell 100 has a cavity 110, a limiting wall 120 is provided in the cavity 110, the limiting wall 120 encloses a mounting cavity 130 and an air outlet cavity 140 that are spaced apart, and a positioning member 150 is provided on the cavity wall of the mounting cavity 130; the baffle 200 is detachably connected to the limiting wall 120, and is provided between the mounting cavity 130 and the air outlet cavity 140, and the baffle 200 has a mounting hole 210 that is connected to both the mounting cavity 130 and the air outlet cavity 140; the isolating member 200 is detachably connected to the limiting wall 120, and is provided between the mounting cavity 130 and the air outlet cavity 140, and the isolating member 200 has a mounting hole 210 that is connected to both the mounting cavity 130 and the air outlet cavity 140; Component 300 includes an isolation sleeve 310 and a fan tube 320. The isolation sleeve 310 is arranged in the installation cavity 130. The isolation sleeve 310 is used to be installed on the fan, and a matching piece 330 is provided on the outside of the isolation sleeve 310. The matching piece 330 is used to plug and cooperate with the positioning piece 150 to install the isolation sleeve 310 in the installation cavity 130. One end of the fan tube 320 is connected to the isolation sleeve 310 and is used to communicate with the air outlet of the fan. The other end of the fan tube 320 extends to the installation hole 210 to communicate with the air outlet cavity 140, and the fan tube 320 is detachably connected to the hole wall of the installation hole 210.

[0040] Specifically, the present application is to install the isolation sleeve 310 on the fan, and to plug and match the fitting 330 on the outside of the isolation sleeve 310 with the positioning piece 150 on the cavity wall of the installation cavity 130 to realize the positioning of the fan, and to connect the fan outlet with the fan through one end of the fan tube 320, and the other end extends to the installation hole 210 and communicates with the air outlet cavity 140 to realize guiding the airflow from the fan outlet to the air outlet cavity 140. Since the isolation sleeve 310 can be plugged and matched with the positioning piece 150 on the cavity wall of the installation cavity 130 through the fitting 330, the isolation sleeve 310 can be removed relative to the cavity wall of the installation cavity 130, and the fan tube 320 can be removed relative to the hole wall of the installation hole 210. Therefore, when it is necessary to replace a fan of different shape or size, it is only necessary to replace the adapted isolation piece 300 to adapt it to the shape contour of the new fan, so as to achieve the installation effect adapted to different fans, thereby expanding the scope of application of the ventilator host structure.

[0041] Among them, the setting that the partition 200 can be disassembled relative to the limiting wall 120 can facilitate the disassembly of the isolation member 300 relative to the cavity wall of the installation cavity 130, and when the adjustment of the inclination angle of the fan tube 320 is restricted, the adaptive partition 200 can also be replaced to further improve the applicability of the ventilator host structure.

[0042] Among them, for fans of different shapes and sizes, the specific adjustment process is: adjusting the outer dimensions of the isolation sleeve 310 so that the isolation sleeve 310 is adapted to the outer contour of the fan;

[0043] Adjust the size and installation position of the fitting 330 outside the isolation sleeve 310 so that the fitting 330 is plugged into and mated with the positioning member 150 to achieve installation of the isolation sleeve 310;

[0044] Adjust the installation position of the fan tube 320 relative to the isolation sleeve 310 so that the fan tube 320 is connected to the air outlet of the fan, and change the extension length of the fan tube 320 so that the end of the fan tube 320 away from the isolation sleeve 310 can extend to one side of the barrier 200.

[0045] It should be noted that when the installation position or inclination angle of the fan tube 320 is restricted, the position of the mounting hole 210 on the partition 200 can also be adjusted so that the end of the fan tube 320 away from the isolation sleeve 310 can extend into the mounting hole 210 and cooperate with the hole wall of the mounting hole 210 to realize the installation of the new fan.

[0046] Furthermore, the shell member 100 includes an upper shell 170 and a lower shell 160. The upper shell 170 is detachably covered on the lower shell 160. The limiting wall 120 is arranged in the lower shell 160. The installation cavity 130 and the air outlet cavity 140 are both arranged in the lower shell 160. When the upper shell 170 is disassembled relative to the lower shell 160, it can facilitate the disassembly of the isolation member 300 and the barrier member 200.

[0047] Among them, a seal 180 is also provided between the upper shell 170 and the lower shell 160. By setting the seal 180, the various chambers formed by the upper shell 170 and the lower shell 160 can be sealed to prevent air flow from flowing out from the gap between the upper shell 170 and the lower shell 160, thereby affecting the user's inhalation effect.

[0048] It should be noted that the instructions are attached Figure 2 For example, XX' is defined as the first direction, which is the arrangement direction of the upper shell 170 and the lower shell 160; ZZ' is defined as the third direction, which is the arrangement direction of the installation cavity 130 and the air outlet cavity 140; and YY' is defined as the second direction, which is perpendicular to the first and second directions. For ease of description, the following description refers to the first, second, and third directions.

[0049] See Figure 1 、 Figure 2 and Figure 3 , Figure 3 A schematic diagram of the isolation and barrier elements in a ventilator mainframe structure according to one embodiment of the present application. In one embodiment, the positioning member 150 includes a first positioning portion, and the mating member 330 includes a mating portion 331. The mating portion 331 is connected to the sidewall of the isolation sleeve 310 and extends away from the isolation sleeve 310. The mating portion 331 is configured to engage with the first positioning portion.

[0050] Specifically, the first positioning portion is provided at a position corresponding to the side wall of the isolation sleeve 310. The mating portion 331 engages with the first positioning portion to restrict the position of the isolation sleeve 310 and enable installation of the isolation sleeve 310. When replacing a fan of a different size or type, the inner contour of the isolation sleeve 310 can be redesigned to match the outer contour of the new fan. The extended length of the mating portion 331 can be changed so that the mating portion 331 engages with the first positioning portion, thereby enabling installation of the isolation sleeve 310 adapted to the new fan within the installation cavity 130.

[0051] Among them, since the isolation sleeve 310 in the present application cooperates with the first positioning portion through the matching portion 331 on the side wall, the isolation sleeve 310 can be suspended relative to the cavity wall of the installation cavity 130, thereby increasing the adaptability to the fan height.

[0052] See Figure 1 、 Figure 2 and Figure 3 In one embodiment, the mating portion 331 includes a mating block and a connecting arm 332, one end of the connecting arm 332 is connected to the isolation sleeve 310, and the other end extends to the side away from the isolation sleeve 310 and is connected to the mating block, one of the first positioning portion and the mating block is configured with a snap-fitting protrusion, and the other is configured with a snap-fitting groove for plugging with the snap-fitting protrusion.

[0053] Specifically, by plugging and fitting the snap-fit protrusions and the snap-fit grooves, the isolation sleeve 310 is stably mounted on the wall of the mounting cavity 130, thereby reducing the shaking of the blower during operation and improving the reliability of the ventilator mainframe structure.

[0054] Furthermore, the snap-fit protrusion is arranged on the cavity wall of the installation cavity 130, the snap-fit groove is arranged on the mating block, and the notch of the snap-fit groove faces the lower shell 160, so that when the snap-fit protrusion and the snap-fit groove are plugged in and matched along the first direction, they can also play a stabilizing supporting role for the isolation sleeve 310, so that the lower side of the isolation sleeve 310 can be suspended relative to the isolation sleeve 310, thereby being able to adapt to a fan with a large size in the height direction, thereby improving the adaptability of the ventilator host structure.

[0055] In other embodiments, the snap-fit protrusion may be provided on the matching block, and the snap-fit groove may be provided on the cavity wall of the installation cavity 130 , with the opening of the snap-fit groove facing upward.

[0056] See Figure 1 、 Figure 2 and Figure 4 , Figure 4 A schematic diagram of an isolation member in a ventilator mainframe structure according to one embodiment of the present application. In one embodiment, the positioning member 150 includes a second positioning portion, and the mating member 330 includes a support column 333. The support column 333 is connected to the bottom wall of the isolation sleeve 310 and extends away from the isolation sleeve 310. The support column 333 is configured to engage with the second positioning portion to support the isolation sleeve 310.

[0057] Specifically, the second positioning portion is positioned corresponding to the bottom wall of the isolation sleeve 310. The support column 333 engages with the second positioning portion to stably support the isolation sleeve 310 and restrict its position, enabling installation of the isolation sleeve 310. When replacing a fan of a different size or type, the length of the support column 333 can be adjusted to accommodate the installation height of the new fan.

[0058] Among them, when the outer contour of the fan is large, the gap between the isolation sleeve 310 and the cavity wall of the installation cavity 130 is small, and it is difficult to set the matching part 331 on the side wall of the isolation sleeve 310. Therefore, the structural characteristics of the isolation sleeve 310 can be optimized, and the original ribs and matching blocks can be removed. The installation of the isolation sleeve 310 can be achieved only by setting a support column 333 at the bottom of the isolation sleeve 310, thereby further improving the adaptability of the ventilator host structure.

[0059] Furthermore, the number of the support columns 333 is at least three, and they are evenly spaced around the circumference of the isolation sleeve 310 , thereby stably supporting the isolation sleeve 310 .

[0060] In another embodiment, the positioning member 150 includes a first positioning portion and a second positioning portion, and the mating member 330 includes a mating portion 331 and a support column 333. The mating portion 331 is connected to the side wall of the isolation sleeve 310 and is plugged into and matched with the first positioning portion. The support column 333 is connected to the bottom wall of the isolation sleeve 310 and is plugged into and matched with the second positioning portion to stably install the isolation sleeve 310 in the installation cavity 130.

[0061] See Figure 1 、 Figure 2 and Figure 4In one embodiment, the outer dimensions of support column 333 gradually expand from the end of support column 333 toward the direction of support column 333 approaching isolation sleeve 310, i.e., support column 333 is conical. This allows the end of support column 333 to deform easily, effectively buffering vibrations generated during fan operation, thereby reducing noise generated during fan operation, while also accommodating the installation of larger fans. Preferably, isolation sleeve 310 is made of soft rubber.

[0062] Furthermore, the end of the support column 333 is in a conical shape with a vertex angle of 15°-45°. Preferably, the vertex angle of the end of the support column 333 is 30°.

[0063] See Figure 1 、 Figure 2 and Figure 4 In one embodiment, the support column 333 has an inclination angle of 30°-90° with the horizontal direction. Preferably, the support column 333 has a certain inclination angle, so as to improve the stability of the support for the isolation sleeve 310 and reduce the shaking of the isolation sleeve 310.

[0064] See Figure 1 and Figure 2 In one embodiment, one of the limiting wall 120 and the barrier 200 is provided with a groove 121 , and the other is provided with a protrusion 220 , and the protrusion 220 is plugged into and fitted with the groove 121 .

[0065] Specifically, the barrier 200 is provided with protrusions 220 on both sides of the second direction. When the upper housing 170 is disassembled from the lower housing 160, the barrier 200 can be easily moved along the first direction relative to the retaining wall 120 to escape from the lower housing 160. This facilitates installation and removal of the barrier 200 when replacing a blower of a different size or type, and facilitates replacement of a newly designed barrier 200, thereby improving the convenience of the ventilator mainframe structure. The barrier 200 also has a protrusion 220 on the side facing the lower housing 160, and the lower housing 160 is provided with a groove 121 corresponding to the protrusion 220, thereby improving the sealing and stability of the connection between the bottom of the barrier 200 and the lower housing 160. In other embodiments, the groove 121 can also be provided on the barrier 200.

[0066] See Figure 1 、 Figure 2 and Figure 5 , Figure 5 Schematic diagram of a baffle in the main structure of a ventilator provided in one embodiment of the present application Figure 1In one embodiment, the barrier member 200 includes a fixed plate 230 and a matching plate 240. The fixed plate 230 is detachably connected to the limiting wall 120 and has an avoidance hole 233. The matching plate 240 is slidably connected to the fixed plate 230 along a preset direction and covers the avoidance hole 233. The mounting hole 210 is located on the matching plate 240 and communicates with the avoidance hole 233. The preset direction is perpendicular to the arrangement direction of the mounting cavity 130 and the air outlet cavity 140.

[0067] Specifically, since the mating plate 240 is connected to the fixed plate 230 by sliding along a preset direction, the position of the mounting hole 210 on the mating plate 240 can be adjusted in the preset direction. Therefore, when replacing fans of different sizes or types, the mounting hole 210 can be adjusted by adjusting the position of the mating plate 240 relative to the fixed plate 230 in the preset direction to adapt to the fan tube 320 of the new fan, thereby avoiding the need to disassemble and replace the partition 200, and further saving costs. Among them, the preset direction in this application can be the first direction, the second direction, or any direction perpendicular to the third direction. This embodiment is described by taking the preset direction as the first direction as an example, for example Figure 6 .

[0068] See Figure 1 、 Figure 2 、 Figure 5 and Figure 6 , Figure 6 Schematic diagram of a baffle in the main structure of a ventilator provided in one embodiment of the present application Figure 2 In one embodiment, the barrier member 200 further includes at least two elastic members 250, and the mating plate 240 includes two mating plate bodies 241. The two mating plate bodies 241 are both slidably connected to the fixed plate 230 along a preset direction. The two mating plate bodies 241 are each provided with a recessed portion 242 on opposite sides. An elastic member 250 is provided between the opposite ends of the two mating plate bodies 241 and the fixed plate 230. The elastic member 250 is used to apply a thrust to the mating plate bodies 241 so that the two mating plate bodies 241 abut against each other, thereby enclosing the mounting hole 210 through the recessed portion 242.

[0069] Specifically, the arrangement of the mating plate 240 including two mating plate bodies 241 facilitates separation of the two mating plates 240, thereby facilitating disassembly between the fan tube 320 and the mounting hole 210, thereby improving the efficiency of disassembly of the isolation member 300. The elastic member 250 applies a thrust to the corresponding mating plate bodies 241, ensuring a stable fit between the two mating plate bodies 241 to compress the fan tube 320, thereby ensuring connection stability and preventing airflow within the air outlet cavity 140 from leaking through the gap between the fan tube 320 and the wall of the mounting hole 210. Preferably, the elastic member 250 is a spring, and its extension direction is the same as the sliding direction of the mating plate bodies 241 and the fixing plate 230.

[0070] Furthermore, the pipe mouth of the fan pipe 320 is provided with a limiting groove 321 arranged around the circumference, and the limiting groove 321 is used to engage with the matching plate 241 to prevent the fan pipe 320 from moving relative to the hole wall of the mounting hole 210, thereby improving the connection stability.

[0071] See Figure 1 、 Figure 2 、 Figure 5 and Figure 6 In one embodiment, the fixed plate 230 includes a frame 231 and a fixed plate body 232, the frame 231 is connected to the fixed plate body 232, and the frame 231 is detachably connected to the limiting wall 120, the avoidance hole 233 is set on the fixed plate body 232, the matching plate 240 is in contact with the fixed plate body 232, and both ends of the fixed plate body 232 in a direction perpendicular to the preset direction are in contact with the frame 231, and the elastic member 250 is set between the frame 231 and the matching plate 240.

[0072] Specifically, the frame 231 surrounds the fixed plate 232 and is protruded relative to the fixed plate 232 on the side of the fixed plate 232 facing the mating plate 240. This allows both ends of the mating plate 241 in the second direction to abut against the frame 231, thereby providing a guide and allowing the mating plate 241 to slide stably in the first direction relative to the fixed plate 230. One end of the elastic member 250 is connected to the frame 231, and the other end is connected to the corresponding mating plate 241.

[0073] Furthermore, an auxiliary block is provided on one side between the mating plate 241 and the frame 231, and an auxiliary groove is provided on the other side. The auxiliary block and the auxiliary groove are matched with each other to stably limit the separation of the mating plate 241 relative to the frame 231, so that the mating plate 241 and the fixed plate 232 are stably abutted to avoid gas leakage in the air outlet cavity 140.

[0074] See Figures 1-6The present application also provides a ventilator, comprising the ventilator host structure described in any of the above embodiments. In the present application, an isolation sleeve 310 is mounted on the fan, and the matching piece 330 on the outside of the isolation sleeve 310 is plugged into and matched with the positioning piece 150 on the cavity wall of the installation cavity 130 to achieve the positioning of the fan, and one end of the fan pipe 320 is connected to the air outlet of the fan, and the other end extends to the installation hole 210 and communicates with the air outlet cavity 140 to guide the airflow from the fan outlet to the air outlet cavity 140. Since the isolation sleeve 310 can be plugged into and matched with the positioning piece 150 on the cavity wall of the installation cavity 130 through the matching piece 330, the isolation sleeve 310 can be removed relative to the cavity wall of the installation cavity 130, and the fan pipe 320 can be removed relative to the hole wall of the installation hole 210. Therefore, when it is necessary to replace a fan of a different shape or size, it is only necessary to replace the adapted isolation piece 300 to adapt it to the shape contour of the new fan, so as to achieve the installation effect that adapts to different fans, thereby expanding the scope of application of the ventilator host structure.
