Description

Technical Field

[0001] This application belongs to the field of ventilator technology, and specifically relates to a ventilator. Background Technology

[0002] As a common medical device, ventilators play a vital role in modern medicine, primarily assisting and maintaining respiration, improving gas exchange, and reducing the burden on respiratory muscles. The working principle of a ventilator is mainly based on the mechanical drive that generates positive pressure during the inspiratory phase, forcing oxygen-rich gas into the lungs to help the body complete the inhalation process. When the lung pressure rises to a certain level, the ventilator stops supplying air, the expiratory valve opens, and the body's chest and lungs passively recoil, thus exhaling and completing the respiratory process to achieve effective gas exchange.

[0003] Specifically, during the inhalation phase, the ventilator relies on external air, using mechanical drive to increase the pressure of the external air and force it into the lungs, assisting the patient in completing the inhalation action. For users in areas with drier air, some ventilators are also equipped with humidifiers. The air entering the ventilator is first humidified by the humidifier, increasing the air's moisture content, and then the ventilator forces the humidified air into the user's lungs, thus ensuring the humidification of the user's respiratory tract and reducing the risk of respiratory infections. For users in areas with more humid air, a humidifier is not necessary. Currently, ventilators on the market are mainly divided into those with humidifiers and those without. For users who frequently change their usage environment, such as those who travel frequently for work, this may not provide a good fit. Utility Model Content

[0004] This application provides a ventilator to solve the technical problem that traditional ventilators are poorly adaptable to areas with high or low air humidity.

[0005] The technical solution adopted in this application is as follows:

[0006] A ventilator includes a body, which is divided into a first mounting area and a second mounting area by a partition. The partition has an air inlet and an air outlet. The ventilator also includes a connecting component detachably mounted in the second mounting area. The connecting component includes a connecting pipe. When the connecting component is mounted in the second mounting area, the two ends of the connecting pipe are connected to the air inlet and the air outlet, respectively.

[0007] The ventilator described in this application also includes the following additional technical features:

[0008] The communication component also includes a housing, the housing having an internal mounting cavity with two communication ports. The communication pipe is at least partially located within the mounting cavity, with one end of the communication pipe connected to the air inlet through one of the communication ports and the other end connected to the air outlet through the other communication port.

[0009] The connecting pipe is installed on the outer shell. One of the outer shell and the body is provided with a snap-fit ​​part, and the other is provided with a fastening part. The outer shell is detachably connected to the body through the snap-fit ​​part and the fastening part. When the outer shell is installed on the body, the connecting pipe is connected to the air inlet and the air outlet.

[0010] The second mounting area has an opening on the side opposite to the first mounting area. The housing can be pushed into the second mounting area through the opening. The fastening part is located on the side of the body near the opening. The snap-fit ​​part is located on the top of the housing. The housing also has a pressing part located above the snap-fit ​​part. The pressing part can move downward to drive the snap-fit ​​part to disengage from the fastening part.

[0011] The outer casing includes a housing and a cover. The cover is disposed on the side of the housing near the opening. The snap-fit ​​portion and the pressing portion are installed on the cover. The housing is provided with an elastic reset member located below the pressing portion, and the elastic reset member abuts against the pressing portion.

[0012] The housing is provided with multiple slots, and the cover is provided with multiple buckles. The cover is detachably connected to the housing by the snap-fit ​​of the buckles and the slots.

[0013] The outer casing has a pushing direction that pushes into the second mounting area along the opening. Along the pushing direction, the outer casing has an outwardly protruding guide protrusion, and the body has a guide groove that aligns with the guide protrusion. The guide protrusion is located in the guide groove to guide the outer casing to move along the pushing direction.

[0014] The two side plates of the housing are respectively provided with limiting grooves facing the cover. The limiting grooves extend laterally. The cover is provided with limiting ribs. The inner side of the limiting ribs is provided with limiting plates. When the cover is connected to the housing, the limiting ribs are located in the limiting grooves, and the limiting plates abut against the inner wall of the cover.

[0015] The bottom wall of the machine body has a heating plate mounting port, and there is a clearance between the outer shell and the heating plate mounting port.

[0016] The bottom of the housing is provided with a support rib extending along the pushing direction. The support rib is located on the side of the heating plate mounting port. During the movement of the housing, the support rib slides along the upper surface of the bottom wall of the machine body.

[0017] The connecting pipe is U-shaped, and a sealing ring is provided at the opening of the connecting pipe. A first sealing sleeve is provided inside the air inlet and the air outlet. The first sealing sleeve has an elastic sealing part located outside the air inlet and the air outlet, and the sealing ring abuts against the elastic sealing part.

[0018] The connecting pipe is U-shaped, and a sealing ring is provided at the opening of the connecting pipe. A second sealing sleeve is provided inside the air inlet and the air outlet, and the sealing ring is sleeved on the second sealing sleeve.

[0019] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0020] 1. The ventilator of this application is divided into a first mounting area and a second mounting area by a separator. The first mounting area can be used to install components such as a compressor and control panel, while the second mounting area can be used to install a connecting component or a humidifier. When the ventilator is used in areas with low humidity and requires humidification, the humidifier can be installed in the second mounting area. The inlet and outlet pipes of the compressor in the first mounting area are then connected to the inlet and outlet, respectively, to achieve the function of humidifying the air and meet the needs of users in dry areas for breathing humidified air. Furthermore, the separator separates the components in the first mounting area from the humidifier in the second mounting area. When water leaks out of the humidifier due to vibration or other factors, the separator effectively reduces the probability of water flowing into the first mounting area, ensuring the operational stability of the components in the first mounting area. When the ventilator is used in areas with high humidity and does not require humidification, the humidifier in the second mounting area can be removed, and a connecting component can be installed in the second mounting area. The inlet and outlet are connected by a connecting pipe to achieve internal gas circulation. The ventilator of this application is suitable for both high and low humidity areas, making it well-suited for users who frequently change their environment, such as those who travel frequently for work.

[0021] 2. As a preferred embodiment of this application, the outer shell is provided such that the connecting tube is at least partially located inside the mounting cavity, which can provide a certain degree of protection and shielding for the connecting tube, prevent the connecting tube from being exposed to the user's field of vision, and improve the overall appearance of the ventilator, thus helping to enhance the user's sensory experience.

[0022] 3. In a preferred embodiment of this application, the connecting tube is installed on the outer casing. This allows the outer casing to not only function as a mounting cavity with the body, but also to provide a mounting position for the connecting tube. This high degree of integration helps optimize the ventilator's structural design. Furthermore, the outer casing and the body are respectively provided with snap-fit ​​and fastening parts, allowing for easy installation and removal of the outer casing from the body. When the humidifier needs to be installed, simply releasing the snap-fit ​​and fastening parts allows the outer casing and connecting tube to be removed from the body together, increasing user convenience. In addition, after the outer casing is installed on the body, the connecting tube is aligned with the air inlet and outlet, thus connecting the air inlet and outlet. This eliminates the need for the user to precisely align the connecting tube with the air inlet and outlet, significantly reducing the difficulty of installing the connecting components and further enhancing the user experience.

[0023] 4. In a preferred embodiment of this application, an opening is provided in the second mounting area, allowing the housing to be pushed into the second mounting area through the opening. When installing the housing and connecting components, it is only necessary to align the housing with the opening and then push the housing inward along the extension direction of the second mounting area, making the entire installation process convenient. Furthermore, the fastening part is located on the side of the body near the opening, the snap-fit ​​part is located on the top of the housing, and a pressing part is provided above the snap-fit ​​part. When disassembling the housing, the user only needs to press down on the pressing part to separate the snap-fit ​​part from the snap-fit ​​part, thereby achieving disassembly of the housing and reducing the user's disassembly and assembly burden.

[0024] 5. As a preferred embodiment of this application, by providing a guide protrusion on the housing and a guide groove on the body for alignment, when the housing enters the second installation area, the guide protrusion is located in the guide groove and guides the housing to move in the pushing direction to achieve engagement with the body. This prevents the housing from getting stuck with the body due to the user's force deviation or other factors during the movement, which helps to improve the smoothness of the housing installation and optimize the user's disassembly and assembly experience.

[0025] 6. In a preferred embodiment of this application, a heating plate mounting port is provided on the bottom wall of the device for mounting a heating plate. When the ventilator is used in areas with low air humidity and low temperature and a humidifier needs to be installed, the heating plate can heat the humidifier, thereby increasing the temperature of the water inside the humidifier and allowing the user to inhale warmer air, thus optimizing the user experience. The clearance between the heating plate mounting port and the outer casing effectively prevents the outer casing from rubbing against the heating plate bracket when pushed into the second mounting area, helping to ensure the working stability of the heating plate.

[0050] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0051] Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0055] like Figure 1 , Figure 2 As shown, a ventilator includes a body 1, which is divided into a first mounting area 2 and a second mounting area 3 by a partition 4. The partition 4 has an air inlet 41 and an air outlet 42. The ventilator also includes a connecting component that is detachably installed in the second mounting area 3. The connecting component includes a connecting pipe 5. When the connecting component is installed in the second mounting area 3, the two ends of the connecting pipe 5 are connected to the air inlet 41 and the air outlet 42, respectively.

[0056] The body 1 of the ventilator of this application is divided into a first mounting area 2 and a second mounting area 3 by a partition 4. The first mounting area 2 can be used to install components such as compressors and control panels, while the second mounting area 3 can be used to install connecting components or humidifiers. When the ventilator is used in areas with low humidity and requires humidification, the humidifier can be installed in the second mounting area 3. The air inlet pipe and air outlet pipe of the compressor in the first mounting area 2 are then connected to the air inlet 41 and air outlet 42, respectively, to achieve the function of humidifying the air and meet the needs of users in dry areas for breathing humidified air. Furthermore, the partition 4 separates the components in the first mounting area 2 from the humidifier in the second mounting area 3. When water in the humidifier leaks out due to shaking of the machine body or other factors, the partition 4 can effectively reduce the probability of water flowing into the first mounting area 2, ensuring the working stability of the components in the first mounting area 2. When the ventilator is used in a high-humidity area without the need for air humidification, the humidifier in the second mounting area 3 can be removed, and a connecting assembly can be installed in the second mounting area 3. The air inlet 41 and the air outlet 42 are connected through the connecting pipe 5 to achieve internal gas circulation. Therefore, the ventilator of this application can be used in both high-humidity and low-humidity areas, making it well-suited for users who frequently change their environment, such as those who travel frequently for work.

[0057] Specifically, the second mounting area 3 and the humidifier are each provided with detachable fixing components to facilitate the detachable connection between the humidifier and the second mounting area 3.

[0058] As a preferred embodiment of this application, such as Figures 3 to 5 As shown, the connecting assembly also includes a housing 6, inside which is a mounting cavity 10. The mounting cavity 10 has two connecting ports 101. The connecting tube 5 is at least partially located within the mounting cavity 10. One end of the connecting tube 5 is connected to the air inlet 41 through one connecting port 101, and the other end is connected to the air outlet 42 through the other connecting port 101. The housing 6 ensures that the connecting tube 5 is at least partially located within the mounting cavity 10, providing some protection and shielding for the connecting tube 5, preventing it from being exposed to the user's view, and improving the overall appearance of the ventilator, thus enhancing the user's sensory experience.

[0059] As a preferred embodiment of this implementation, such as Figure 3 , Figure 4 As shown, the connecting pipe 5 is installed on the outer shell 6. One of the outer shell 6 and the body 1 is provided with a snap-fit ​​part 61, and the other is provided with a fastening part 11. The outer shell 6 is detachably connected to the body 1 through the snap-fit ​​cooperation between the snap-fit ​​part 61 and the fastening part 11. When the outer shell 6 is installed on the body 1, the connecting pipe 5 is connected to the air inlet 41 and the air outlet 42.

[0060] The connecting tube 5 is installed on the outer shell 6, which, in addition to its function of forming the mounting cavity 10 with the body 1, further integrates the function of providing a mounting position for the connecting tube 5. This high degree of functional integration helps optimize the structural design of the ventilator. Furthermore, the outer shell 6 and the body 1 are respectively provided with a snap-fit ​​part 61 and a fastening part 11, allowing the outer shell 6 to be easily installed or detached from the body 1. When the humidifier needs to be installed, simply release the snap-fit ​​part 61 and the fastening part 11 to remove the outer shell 6 and the connecting tube 5 together from the body 1, increasing user convenience. In addition, after the outer shell 6 is installed on the body 1, the connecting tube 5 is aligned with the air inlet 41 and the air outlet 42, thus connecting the air inlet 41 and the air outlet 42. This eliminates the need for the user to precisely align the connecting tube 5 with the air inlet 41 and the air outlet 42, significantly reducing the difficulty of installing the connecting components and further enhancing the user experience.

[0061] As a preferred example in this embodiment, such as Figure 2 , Figure 3As shown, the second mounting area 3 has an opening on the side opposite to the first mounting area 2. The outer casing 6 can be pushed into the second mounting area 3 through the opening. The fastening part 11 is located on the side of the body 1 near the opening, and the locking part 61 is located on the top of the outer casing 6. The outer casing 6 also has a pressing part 62 located above the locking part 61. The pressing part 62 can move downward to drive the locking part 61 to disengage from the fastening part 11. By providing an opening in the second mounting area 3, the outer casing 6 can be pushed into the second mounting area 3 through the opening. When installing the outer casing 6 and the connecting components, it is only necessary to align the outer casing 6 with the opening and then push the outer casing 6 inward along the extension direction of the second mounting area 3. The entire installation process is relatively convenient. In addition, the fastening part 11 is provided on the side of the body 1 near the opening, the snap-fit ​​part 61 is provided on the top of the outer shell 6, and the pressing part 62 is provided above the snap-fit ​​part 61. When disassembling the outer shell 6, the user only needs to press down the pressing part 62 to separate the snap-fit ​​part 61 from the fastening part 11, thereby disassembling the outer shell 6 and reducing the user's disassembly and assembly pressure.

[0062] Preferably, the pressing part 62 is hinged to the outer shell 6, one end of the snap-fit ​​part 61 is connected to the pressing part 62, and the other end extends toward the fastening part 11 and has a snap-fit ​​protrusion. The fastening part 11 is provided with a slot that matches the snap-fit ​​protrusion.

[0063] As a preferred approach in this example, such as Figures 3 to 7 As shown, the outer casing 6 includes a housing 63 and a cover 64. The cover 64 covers the side of the housing 63 near the opening. A snap-fit ​​part 61 and a pressing part 62 are installed on the cover 64. The housing 63 has an elastic reset member 631 located below the pressing part 62, which abuts against the pressing part 62. By configuring the outer casing 6 to include the housing 63 and the cover 64, the housing 63 can provide a relatively closed installation environment for the connecting pipe 5, which helps to improve the installation stability of the connecting pipe 5. Integrating the snap-fit ​​part 61 and the pressing part 62 into the cover 64 concentrates the functions of the cover 64 and reduces the processing operations on the housing 63. Based on this, the housing 63 is provided with an elastic reset member 631 located below the pressing part 62. When installing the housing 6, the user first presses the pressing part 62 to drive the locking part 61 downward so that the locking part 61 can move to below the fastening part 11. Then, the user releases the pressing part 62, and the pressing part 62 will move upward under the elastic action of the elastic reset member 631 and drive the locking part 61 to fasten into the fastening part 11, thereby realizing the connection between the housing 6 and the body 1.

[0064] Preferably, the elastic reset member 631 can be a spring.

[0065] This method does not limit the connection relationship between the housing 63 and the cover 64. In a preferred embodiment, such as... Figure 6 , Figure 7As shown, the housing 63 has multiple slots 632, and the cover 64 has multiple snap fasteners 641 aligned with it. The cover 64 is detachably connected to the housing 63 through the snap-fit ​​engagement of the snap fasteners 641 and the slots 632. In this design, the cover 64 and the housing 63 are detachable, facilitating their separate manufacturing and assembly. In one design, the cover 64 and the housing 63 are fixedly connected.

[0066] As another preferred method in this example, such as Figures 2 to 4 As shown, the outer casing 6 has a pushing direction that allows it to be pushed into the second mounting area 3 along the opening. Along the pushing direction, the casing 63 has an outwardly protruding guide protrusion 633, and the body 1 has a guide groove 12 that aligns with the guide protrusion 633. The guide protrusion 633 is located within the guide groove 12 to guide the outer casing 6 to move along the pushing direction. By providing the guide protrusion 633 on the casing 63 and the guide groove 12 aligned on the body 1, when the casing 63 enters the second mounting area 3, the guide protrusion 633 is located within the guide groove 12 and guides the casing 63 to move along the pushing direction to achieve engagement with the body 1. This prevents the casing 63 from jamming with the body 1 during movement due to user force deviation or other factors, thus improving the smoothness of casing 63 installation and optimizing the user's disassembly and assembly experience.

[0067] Preferably, such as Figure 6 , Figure 7 As shown, the two side plates of the housing 63 are respectively provided with limiting grooves 634 facing the cover 64. The limiting grooves 634 extend laterally. The cover 64 is provided with limiting ribs 642, and the inner side of the limiting ribs 642 is provided with a limiting plate 643. When the cover 64 is connected to the housing 63, the limiting ribs 642 are located in the limiting grooves 634, and the limiting plate 643 abuts against the inner wall of the cover 64. The setting of the limiting ribs 642 and the limiting grooves 634 provides the user with tactile feedback after the housing is in place, to indicate to the user that the housing 6 has been installed in place; on the other hand, the insertion of the limiting ribs 642 into the limiting grooves 634 and the abutment of the limiting plate 643 against the inner wall of the cover 64 can improve the tightness of the connection between the housing 6 and the body 1, and reduce the probability of relative displacement between the two under the action of external force.

[0068] Furthermore, such as Figure 2 , Figure 8As shown, a heating plate mounting opening 13 is provided on the bottom wall of the body 1, and a clearance is provided between the outer shell 6 and the heating plate mounting opening 13. The heating plate mounting opening 13 on the bottom wall of the body 1 can be used to install a heating plate. When the ventilator is used in areas with low air humidity and low temperature and a humidifier needs to be installed, the heating plate can heat the humidifier, thereby increasing the temperature of the water inside the humidifier, allowing the user to inhale warmer air and improving the user experience. The clearance between the heating plate mounting opening 13 and the outer shell 6 effectively prevents the outer shell 6 from rubbing against the heating plate bracket when pushed into the second mounting area 3, helping to ensure the working stability of the heating plate. Preferably, a heating plate is installed inside the heating plate mounting opening 13.

[0069] Preferably, such as Figure 8 As shown, the bottom of the housing 63 is provided with a support rib 7 extending along the pushing direction. The support rib 7 is located on the side of the heating plate mounting opening 13. During the movement of the housing 6, the support rib 7 slides against the upper surface of the bottom wall of the body 1. The setting of the support rib 7 has two aspects: firstly, it has a lifting effect on the housing 63, thereby forming a clearance gap between the housing 63 and the heating plate mounting opening 13; secondly, the support rib 7 can provide sliding support for the housing 63. When the housing 63 is pushed in, the housing 63 slides relative to the body 1 by relying on the support rib 7, which reduces the contact area between the housing 63 and the body 1, helps to reduce the frictional resistance encountered by the housing 63 during the pushing process, thereby improving the smoothness of the installation of the housing 6.

[0070] This application does not limit the structural form of the connecting pipe 5, which can be any of the following embodiments:

[0071] Implementation method one: such as Figure 9 , Figure 10 As shown, the connecting pipe 5 is U-shaped, and a sealing ring edge 51 is provided at the opening of the connecting pipe 5. A first sealing sleeve 8 is inserted inside the air inlet 41 and the air outlet 42. The first sealing sleeve 8 has an elastic sealing part 81 located outside the air inlet 41 and the air outlet 42, and the sealing ring edge 51 abuts against the elastic sealing part 81. By setting the sealing ring edge 51 and the first sealing sleeve 8 with the elastic sealing part 81, the sealing ring edge 51 and the elastic sealing part 81 are squeezed together to deform the elastic sealing part 81, which greatly reduces the gap between the first sealing sleeve 8 and the sealing ring edge 51, thereby increasing the sealing performance of the connection between the connecting pipe 5 and the air inlet 41 and the air outlet 42.

[0072] Implementation Method Two: (e.g.) Figure 11 , Figure 12As shown, the connecting pipe 5 is U-shaped, and a sealing ring cylinder 52 is provided at the opening of the connecting pipe 5. A second sealing sleeve 9 is inserted inside the air inlet 41 and the air outlet 42, and the sealing ring cylinder 52 is sleeved on the second sealing sleeve 9. The arrangement of the sealing ring cylinder 52 and the second sealing sleeve 9 allows the connecting pipe 5 to be sleeved on the outside of the second sealing sleeve 9 through the sealing ring cylinder 52, thereby increasing the sealing performance of the connecting pipe 5 with the air inlet 41 and the air outlet 42.
