Description

Technical Field

[0001] This application belongs to the field of medical device technology, specifically relating to a top cover assembly for a respiratory humidification therapy device. Background Technology

[0002] Respiratory humidification therapy devices are mainly used to humidify gases, improve respiratory symptoms, promote drug inhalation, and prevent respiratory dryness. A respiratory humidification therapy device includes a main body, a top cover assembly, and a drive module located inside the main body.

[0003] Due to user placement requirements, humidifiers often need to be transported. Traditional humidifier covers only serve to cover the device and house the display screen. During transport, users must hold the device with both hands, which can easily lead to instability. Furthermore, holding the device with both hands occupies the user's hands, preventing them from performing operations such as opening doors or pressing buttons during transport, causing significant inconvenience. Utility Model Content

[0004] This application provides a top cover assembly for a respiratory humidification therapy device to solve the technical problem of inconvenient transportation of traditional respiratory humidification therapy devices.

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

[0006] A top cover assembly for a respiratory humidification therapy device is installed on the body of the device. The top cover assembly includes a cover body and a lifting member movably connected to the cover body. The lifting member includes a grip portion and a connecting portion rotatably connected to the cover body. The lifting member has a lifting position and a retracted position. The lifting member can switch from the retracted position to the lifting position along a first rotation direction and can switch from the lifting position to the retracted position along a second rotation direction. When the lifting member is in the lifting position, the vertical projection of the grip portion coincides with the center of gravity of the device body.

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

[0008] The cover is provided with a storage platform arranged around its circumference. When the lifting member is in the storage position, the lifting member abuts against the storage platform and the outer surface of the lifting member is flush with the outer surface of the cover.

[0009] The cover is provided with a first limiting part, the first limiting part having a first stop surface, and the connecting part having a limiting protrusion. When the lifting member is in the lifting position, the stop surface abuts against the limiting protrusion to restrict the rotation of the connecting part along the second rotation direction.

[0010] The first limiting part is also provided with an arc-shaped guide surface. Along the first rotation direction, one end of the arc-shaped guide surface is connected to the cover body, and the other end is connected to the first stop surface.

[0011] The cover is also provided with a tactile protrusion adjacent to the first limiting part, and a groove is formed between the tactile protrusion and the arc-shaped guide surface.

[0012] The cover is also provided with a second limiting part, which has a second stop surface. When the lifting member is in the lifting position, the second stop surface abuts against the connecting part to restrict the rotation of the connecting part along the first rotation direction.

[0013] The connecting part is provided with a rotating member, and the cover is provided with a rotating hole adapted to the rotating member. The connecting part is rotatably connected to the cover through the rotating member. It also includes a limiting plate disposed between the connecting part and the cover, and the limiting plate abuts against the rotating member to prevent the rotating member from dislodging from the rotating hole.

[0014] The limiting plate has a first fixing hole, and the cover has a second fixing hole. The limiting plate is connected to the cover by a fixing member that passes through the first fixing hole and the second fixing hole in sequence. The rotating member includes a rotating part located in the rotating hole and a rotating shaft that connects the rotating part to the connecting part. The limiting plate also has a through hole for the rotating shaft to pass through.

[0015] The area of ​​the through hole is smaller than that of the rotating part, and the through hole has a clearance opening so that the rotating shaft can enter the through hole through the clearance opening.

[0016] The through hole is adapted to the shape of the rotating part for the rotating part to pass through. The limiting plate has a first position for aligning the through hole with the rotating hole and a second position for misaligning the through hole with the rotating hole. When the limiting plate is in the second position, the first fixing hole is aligned with the second fixing hole, and the through hole is misaligned with the rotating hole to restrict the rotating part from coming out.

[0017] The cover is provided with a positioning protrusion, and the limiting plate is provided with a positioning groove. The positioning protrusion has a first positioning surface and a second positioning surface, and the positioning groove has a first mating surface and a second mating surface. When the limiting plate is in the first position, the first positioning surface abuts against the first mating surface. When the limiting plate is in the second position, the second positioning surface abuts against the second mating surface.

[0018] The connecting part is provided with a rotating component, and the cover body is provided with a rotating hole adapted to the rotating component. The connecting part is rotatably connected to the cover body through the rotating component. The rotating component includes a rotating part located in the rotating hole and a rotating shaft connecting the rotating part to the connecting part. The cover body is provided with a limiting protrusion outside the rotating hole, and the connecting part is provided with a limiting groove. When the limiting groove is aligned with the limiting protrusion, the rotating part can enter the rotating hole or disengage from the rotating hole. When the limiting groove is misaligned with the limiting protrusion, the limiting protrusion abuts against the connecting part to prevent the rotating part from disengaging from the rotating hole.

[0019] The upper cover assembly also includes a rear cover, which includes a limiting arm located between the rotating part and the connecting part. The limiting arm is provided with a clearance groove for the rotating shaft to pass through, and the limiting arm can stop the rotating part to prevent the rotating part from disengaging from the rotating hole.

[0020] One of the cover and the limiting arm is provided with a mounting slot, and the other is provided with a mounting buckle located in the mounting slot. The cover and the rear cover are engaged with each other through the mounting slot and the mounting buckle.

[0021] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0022] 1. The top cover assembly of this application includes a cover body and a lifting component movably connected to the cover body. When the therapeutic device is not being transported, the lifting component is in the storage position and does not occupy too much external space of the top cover assembly. When the therapeutic device needs to be transported, the lifting component switches to the lifting position. The user lifts the gripping part to lift the cover body and the device body under the action of the connecting part. Then, the user can transport the therapeutic device by holding the lifting component with one hand. This eliminates the need for the user to lift the therapeutic device with both hands for transport, which helps to improve the user experience. Furthermore, the lifting mechanism is rotatably connected to the cover and switches between the storage and lifting positions by rotating along the first and second rotation directions, increasing the efficiency of switching between these positions. Users can easily adjust the position of the lifting mechanism, optimizing the user experience. Additionally, when the lifting mechanism is in the lifting position, the vertical projection of the grip coincides with the center of gravity of the device. This ensures that when the user lifts the device, the point of force applied to the lifting mechanism is on the same vertical plane as the center of gravity, increasing the stability of the device during transport. This prevents unbalanced torque caused by misalignment between the point of force applied and the center of gravity, thus preventing the device from wobbling or tipping over. Simultaneously, it reduces the user's attention required when walking while lifting the device, eliminating the need for extra effort to adjust its position and prevent it from tipping over. Users can focus more on walking itself, further improving the efficiency of transporting the device.

[0023] 2. As a preferred embodiment of this application, the storage platform arranged circumferentially along the cover provides a placement position for the lifting component in the storage position, so that when the therapeutic device is working normally, the lifting component can occupy less external space of the cover, which helps to miniaturize the therapeutic device; on this basis, the outer surface of the lifting component is flush with the outer surface of the cover, making the outer surface of the upper cover assembly more integrated, and there is no obvious misalignment at the contact point between the lifting component and the cover, which helps to improve the aesthetics of the upper cover assembly and optimize the user's visual experience.

[0024] 3. As a preferred embodiment of this application, by providing a limiting protrusion and a first limiting part with a first stop surface, when the user holds the lifting member to drive the therapeutic device, the lifting member can be stably placed in the lifting position under the cooperation of the first stop surface and the first limiting part, thereby ensuring the stability of the device's center of gravity; when the user applies uneven force to the lifting member due to swaying and shaking while walking, the lifting member will not easily rotate in the second rotation direction under the cooperation of the first stop surface and the first limiting part, thus ensuring the stability of the lifting therapeutic device.

[0025] 4. In a preferred embodiment of this application, the arc-shaped guide surface guides the rotating end of the lifting part towards the first stop surface, making the switching of the lifting part from the storage position to the working position smoother. Furthermore, the arc-shaped guide surface provides a certain degree of damping when the lifting part contacts the arc-shaped guide surface during rotation in the first rotation direction, providing the user with force feedback so that the user knows the lifting part is nearing the lifting position. When the lifting part disengages from the arc-shaped guide surface and contacts the first stop surface, the damping effect exerted on the user by the arc-shaped guide surface disappears, allowing the user to know that the lifting part has reached the lifting position through the change in force, thus stopping the rotation. In other words, by providing the arc-shaped guide surface, the rotation of the lifting part in the first direction is guided, and force feedback is also provided to the user, allowing the user to know whether the lifting part has rotated to the lifting position without observing its position.

[0026] 5. As a preferred embodiment of this application, the design of the tactile protrusions and grooves causes a noticeable pause when the lifting component passes through them in sequence, thereby providing the user with force feedback and letting the user know that the lifting component has rotated to the arc-shaped guide surface. By increasing the force and rotating to a certain extent, the lifting component can reach the lifting position.

[0027] 6. In a preferred embodiment of this application, a limiting plate is provided between the connecting part and the cover. After the rotating part on the connecting part is installed with the rotating hole, the limiting plate can restrict the rotating part from coming out of the rotating hole, thus ensuring the installation stability of the rotating part in the rotating hole and ensuring the connection stability between the lifting part and the cover.

[0075] like Figure 1 , Figure 2 As shown, an upper cover assembly for a respiratory humidification therapy device is installed on the body of the device. The upper cover assembly includes a cover body 1 and a lifting member 2 movably connected to the cover body 1. The lifting member 2 includes a gripping part 21 and a connecting part 22 rotatably connected to the cover body 1. The lifting member 2 has a lifting position and a retracted position. The lifting member 2 can switch from the retracted position to the lifting position along a first rotation direction and can switch from the lifting position to the retracted position along a second rotation direction. When the lifting member 2 is in the lifting position, the vertical projection of the gripping part 21 coincides with the center of gravity of the device body.

[0076] Figure 1 The lifting component 2 is in the lifting position. Figure 2 The lifting component 2 is in the storage position. Figure 2Arrow X indicates the first rotation direction, and arrow Y indicates the second rotation direction. The top cover assembly of this application includes a cover body 1 and a lifting member 2 movably connected to the cover body 1. When the therapeutic device is not being transported, the lifting member 2 is in the storage position, not occupying excessive external space of the top cover assembly. When the therapeutic device needs to be transported, the lifting member 2 switches to the lifting position. The user lifts the gripping part 21, causing the cover body 1 and the device body to be lifted by the connecting part 22. Then, the user can transport the therapeutic device by holding the lifting member 2 with one hand. This eliminates the need for the user to lift the therapeutic device with both hands, improving the user experience. Furthermore, the lifting member 2 is rotatably connected to the cover body 1 and switches between the storage and lifting positions by rotating along the first and second rotation directions, increasing the efficiency of switching between the lifting and storage positions. Users can easily adjust the position of the lifting member 2, further optimizing the user experience. Based on this, as... Figure 25 and Figure 26 As shown, the pentagram indicates the location of the machine's center of gravity. When the lifting component 2 is in the lifted position, the vertical projection of the grip 21 coincides with the machine's center of gravity. This ensures that when the user lifts the therapeutic device, the point of force applied by the user to the lifting component 2 is on the same vertical plane as the machine's center of gravity. This helps increase the stability of the therapeutic device during transport, avoiding unbalanced torque caused by misalignment between the lifting force point and the machine's center of gravity. This prevents the therapeutic device from swaying or even tipping over due to unbalanced torque. Simultaneously, it helps reduce the user's attention required when walking while lifting the therapeutic device, avoiding the need for extra effort to adjust its position to prevent it from tipping over. This allows the user to focus more on walking itself, improving the efficiency of transporting the therapeutic device.

[0077] It should be noted that when the lifting part 2 is in the lifting position, the grip part 21 has a certain width in the horizontal direction. Therefore, as long as the projection of the grip part 21 in the vertical direction covers the center of gravity of the body, it can be regarded as the projection of the grip part 21 in the vertical direction coincides with the center of gravity of the body.

[0078] As a preferred embodiment of this application, such as Figure 1As shown, the cover 1 has a storage platform 11 arranged circumferentially thereon. When the lifting member 2 is in the storage position, the lifting member 2 abuts against the storage platform 11, and the outer surface of the lifting member 2 is flush with the outer surface of the cover 1. The storage platform 11 arranged circumferentially along the cover 1 provides a placement position for the lifting member 2 in the storage position, so that when the therapeutic device is working normally, the lifting member 2 can occupy less external space of the cover 1, which helps to miniaturize the therapeutic device. On this basis, the outer surface of the lifting member 2 is flush with the outer surface of the cover 1, which makes the outer surface of the upper cover assembly more integrated, and there is no obvious misalignment at the abutment point of the lifting member 2 and the cover 1, which helps to improve the aesthetics of the upper cover assembly and optimize the user's visual experience.

[0079] Preferably, such as Figure 1 As shown, the upper cover assembly also includes a rear cover 5 located behind the cover body 1. The rear cover 5 and the cover body 1 are staggered to form a storage platform 11 between them. When the lifting member 2 is in the storage position, one side of the outer surface of the lifting member 2 is flush with the outer surface of the cover body 1, and the other side of the outer surface of the lifting member 2 is flush with the outer surface of the rear cover 5.

[0080] As a preferred embodiment of this application, such as Figures 3 to 6 As shown, the cover 1 is provided with a first limiting part 12, which has a first stop surface 121. The connecting part 22 is provided with a limiting protrusion 221. When the lifting member 2 is in the lifting position, the stop surface and the limiting protrusion 221 abut against each other to restrict the rotation of the connecting part 22 in the second rotation direction. By setting the limiting protrusion 221 and the first limiting part 12 with the first stop surface 121, when the user holds the lifting member 2 to drive the therapeutic device, the lifting member 2 can be stably placed in the lifting position under the cooperation of the first stop surface 121 and the first limiting part 12, thereby ensuring the stability of the device's center of gravity. When the user applies uneven force to the lifting member 2 due to swaying while walking, the lifting member 2 will not easily rotate in the second rotation direction under the cooperation of the first stop surface 121 and the first limiting part 12, thus ensuring the stability of the lifting therapeutic device.

[0081] As a preferred embodiment of this implementation, such as Figure 4As shown, the first limiting part 12 is also provided with an arc-shaped guide surface 122. Along the first rotation direction, one end of the arc-shaped guide surface 122 is connected to the cover 1, and the other end is connected to the first stop surface 121. The arc-shaped guide surface 122 guides the rotating end of the lifting part towards the first stop surface 121, making the switching of the lifting part 2 from the storage position to the working position smoother. In addition, the setting of the arc-shaped guide surface 122 makes the lifting part 2, during the rotation along the first rotation direction, generate a certain damping feeling when it comes into contact with the arc-shaped guide surface 122, thereby giving the user a certain force feedback, so that the user can know that the lifting part 2 is close to the lifting position. When the lifting component 2 disengages from the arc-shaped guide surface 122 and abuts against the first stop surface 121, the damping sensation exerted on the user by the lifting component 2 through the arc-shaped guide surface 122 disappears. The user can then perceive the change in force to indicate that the lifting component 2 has reached the lifting position, thus stopping its rotation. In other words, by providing the arc-shaped guide surface 122, the rotation of the lifting component 2 along the first direction is guided, while also providing force feedback to the user, allowing the user to determine whether the lifting component 2 has rotated to the lifting position without needing to observe its position.

[0082] Specifically, in this embodiment, the arc-shaped guide surface 122 has a first end connected to the cover 1 and a second end connected to the first stop surface 121, and the arc-shaped guide surface 122 gradually moves away from the cover 1 from the first end to the second end.

[0083] As a preferred example in this embodiment, such as Figure 4 As shown, the cover 1 is also provided with a tactile protrusion 13 adjacent to the first limiting part 12, and a groove 14 is formed between the tactile protrusion 13 and the arc-shaped guide surface 122. The arrangement of the tactile protrusion 13 and the groove 14 causes a relatively obvious pause when the lifting part 2 passes through them in sequence, thereby giving the user force feedback, letting the user know that the lifting part 2 has rotated to the arc-shaped guide surface 122, and that increasing the force and rotating to a certain extent will reach the lifting position.

[0084] As a preferred embodiment of this application, such as Figure 4 As shown, the cover 1 also has a second limiting part 15, which has a second stop surface 151. When the lifting member 2 is in the lifting position, the second stop surface 151 abuts against the connecting part 22 to restrict the rotation of the connecting part 22 along the first rotation direction. The second stop surface 151 is configured to limit the lifting member 2 when it is in the lifting position. When the user rotates the lifting member 2 along the first rotation direction until the lifting member 2 is rotated to the lifting position, the second stop surface 151 restricts the continued rotation of the lifting member 2. The user can know the position status of the lifting member 2 through force feedback, thus optimizing the user experience.

[0085] This application does not limit the rotational connection method between the lifting component 2 and the cover 1, and it can adopt any of the following embodiments:

[0086] Implementation method one: such as Figure 4 , Figure 8 As shown, the connecting part 22 is provided with a rotating member 222, and the cover 1 is provided with a rotating hole 16 adapted to the rotating member 222. The connecting part 22 is rotatably connected to the cover 1 through the rotating member 222. It also includes a limiting plate 3 disposed between the connecting part 22 and the cover 1. The limiting plate 3 abuts against the rotating member 222 to prevent the rotating member 222 from disengaging from the rotating hole 16. The limiting plate 3 between the connecting part 22 and the cover 1 ensures that when the rotating member 222 on the connecting part 22 is installed with the rotating hole 16, the limiting plate 3 can prevent the rotating member 222 from disengaging from the rotating hole 16, thus guaranteeing the installation stability of the rotating member 222 within the rotating hole 16 and ensuring the connection stability between the lifting member 2 and the cover 1.

[0087] It should be noted that the abutment between the limiting plate 3 and the rotating member 222 mentioned in this embodiment does not mean that the two are in close contact, but that there is a certain gap between them. When the rotating member 222 is working normally, the rotating member 222 and the limiting plate 3 do not contact each other. When the rotating member 222 is affected by external force or other factors and its position is displaced, the limiting plate 3 abuts against the rotating member 222 so that it cannot continue to displace, thereby maintaining the normal rotation of the rotating member 222.

[0088] As a preferred embodiment of this implementation, such as Figure 4 , Figure 8 As shown, the limiting plate 3 has a first fixing hole, and the cover 1 has a second fixing hole. The limiting plate 3 is connected to the cover 1 by fixing members that pass through the first fixing hole and the second fixing hole in sequence. The rotating member 222 includes a rotating part 2221 located in the rotating hole 16 and a rotating shaft 2222 connecting the rotating part 2221 to the connecting part 22. The limiting plate 3 also has a through hole 31 for the rotating shaft 2222 to pass through. The connection between the limiting plate 3 and the cover 1 is achieved by fixing members that pass through the first fixing hole and the second fixing hole in sequence, which helps to increase the installation stability of the limiting plate 3 and enables it to stably restrict the rotating part 2221 from coming out of the rotating hole 16. The through hole 31 allows the limiting plate 3 to limit the rotating part 2221 without affecting the assembly of the rotating part 2221 into the rotating hole 16, which helps to reduce the assembly difficulty of the rotating member 222.

[0089] This embodiment does not limit the structural form of the limiting plate 3, which can be any of the following examples:

[0090] Example 1: such as Figure 4 As shown, the area of ​​the through hole 31 is smaller than that of the rotating part 2221. The through hole 31 has a clearance opening 311 so that the rotating shaft 2222 can enter the through hole 31 through the clearance opening 311. In this example, when assembling the rotating part 222 and the limiting plate 3, the rotating part 222 is installed first. After the rotating part 2221 is installed in the rotating hole 16, the limiting plate 3 is installed. The clearance opening 311 of the limiting plate 3 is aligned with the rotating shaft 2222 and the limiting plate 3 is pushed. After the rotating shaft 2222 is located in the through hole 31, the rotating part 2221 abuts against the limiting plate 3.

[0091] Example 2: such as Figure 9 , Figure 10 As shown, the through hole 31 is adapted to the shape of the rotating part 2221 for the rotating part 2221 to pass through. The limiting plate 3 has a first position in which the through hole 31 is aligned with the rotating hole 16 and a second position in which the through hole 31 is misaligned with the rotating hole 16. When the limiting plate 3 is in the second position, the first fixing hole is aligned with the second fixing hole, and the through hole 31 is misaligned with the rotating hole 16 to restrict the rotating part 2221 from coming out. Figure 10 The limiting plate 3 shown is in the second position. In this example, the limiting plate 3 is assembled first and placed in the first position. Then, the rotating part 2221 and the rotating shaft 2222 are sequentially inserted through the rotating hole 16. After the rotating part 2221 is located in the rotating hole 16, the limiting plate 3 is switched from the first position to the second position. At this time, the insertion hole 31 is misaligned with the rotating hole 16. The rotating part 2221 located in the rotating hole 16 cannot be removed through the insertion hole 31, thereby limiting the rotating part 2221 by the limiting plate 3.

[0092] Preferably, such as Figure 10 As shown, the cover 1 is provided with a positioning protrusion 17, and the limiting plate 3 is provided with a positioning groove 32. The positioning protrusion 17 has a first positioning surface and a second positioning surface, and the positioning groove 32 has a first mating surface and a second mating surface. When the limiting plate 3 is in the first position, the first positioning surface abuts against the first mating surface. When the limiting plate 3 is in the second position, the second positioning surface abuts against the second mating surface.

[0093] The positioning protrusion 17 and the positioning groove 32 provide a positioning function for the limiting plate 3. When the rotating part 222 is installed, the limiting plate 3 remains stable under the abutment of the first positioning surface and the second positioning surface so that the rotating part 2221 and the rotating shaft 2222 can pass through. After the rotating part 222 is installed, the limiting plate 3 is pushed until the second positioning surface abuts against the second mating surface, thereby stabilizing the limiting plate 3 at the position where the clearance hole and the rotating hole 16 are misaligned.

[0094] Implementation Method Two: (e.g.) Figures 11-14 As shown, the connecting part 22 is provided with a rotating member 222, and the cover 1 is provided with a rotating hole 16 adapted to the rotating member 222. The connecting part 22 is rotatably connected to the cover 1 through the rotating member 222. The rotating member 222 includes a rotating part 2221 located in the rotating hole 16 and a rotating shaft 2222 connecting the rotating part 2221 to the connecting part 22. The cover 1 is provided with a limiting protrusion 18 outside the rotating hole 16, and the connecting part 22 is provided with a limiting groove 223. When the limiting groove 223 is aligned with the limiting protrusion 18, the rotating part 2221 can enter the rotating hole 16 or disengage from the rotating hole 16. When the limiting groove 223 is misaligned with the limiting protrusion 18, the limiting protrusion 18 abuts against the connecting part 22 to restrict the rotating part 2221 from disengaging from the rotating hole 16.

[0095] By setting the limiting protrusion 18 and the limiting groove 223, the rotating part 2221 can only enter or exit the rotating hole 16 when the limiting groove 223 and the limiting protrusion 18 are aligned. When the limiting groove 223 and the limiting protrusion 18 are misaligned, the rotating part 2221 cannot be removed from the rotating hole 16 due to the stopping effect of the limiting protrusion 18, thus ensuring the installation stability of the rotating part 2221 in the rotating hole 16 and ensuring the connection stability between the lifting part 2 and the cover 1.

[0096] As a preferred embodiment of this implementation, such as Figure 13 , Figure 14 As shown, the upper cover assembly also includes a rear cover 5, which includes a limiting arm 51 located between the rotating part 2221 and the connecting part 22. The limiting arm 51 is provided with a clearance groove 511 for the rotating shaft 2222 to pass through. The limiting arm 51 can stop the rotating part 2221 to restrict the rotating part 2221 from disengaging from the rotating hole 16. Since the rotating part 2221 still has the risk of coming out of the rotating hole 16 when the lifting member 2 rotates to align the limiting groove 223 with the limiting protrusion 18, by providing the rear cover 5 and the limiting arm 51 on the rear cover 5, when the limiting groove 223 aligns with the limiting protrusion 18 and the lifting member 2 is affected by external force or other factors, causing the rotating part 2221 to tend to come out of the rotating hole 16, the limiting arm 51 can limit and stop the rotating part 2221, thereby eliminating the risk of the rotating part 2221 coming out of the rotating hole 16.

[0097] Preferably, one of the cover 1 and the limiting arm 51 is provided with a mounting groove, and the other is provided with a mounting buckle located in the mounting groove. The cover 1 and the rear cover 5 are engaged with each other through the mounting groove and the mounting buckle. The mounting buckle and the mounting groove enable a detachable connection between the cover 1 and the limiting arm 51. This makes the installation of the limiting arm 51 simpler and helps to improve the installation speed of the rear cover 5. On the other hand, it facilitates the removal of the limiting arm 51 from the cover 1 for inspection or replacement.

[0098] As a preferred embodiment of this application, such as Figure 15 As shown, the cover 1 has a mounting part 19 and a control part 100. The mounting part 19 is mounted on the body. The control part 100 is set at an angle to the mounting part 19 and has a control screen 1001 that extends obliquely. The upper cover assembly also includes a rear cover 5 located between the mounting part 19 and the control part 100. The rear cover 5, the cover 1, and the body cooperate to form a mounting cavity for mounting the drive module.

[0099] The control unit 100 and the mounting unit 19 are arranged at an angle, causing the control screen 1001 mounted on the control unit 100 to extend obliquely, i.e., the control screen 1001 forms a certain angle with the horizontal plane. Users only need to stand in front of the therapeutic device to intuitively obtain information from the control screen 1001 and operate it from the front of the device. Therefore, even when the therapeutic device is placed at a certain distance from the operator, such as in the center of a table, the user does not need to move the therapeutic device; they can observe and operate the control screen 1001 from the edge of the table, optimizing the user experience. In addition, the upper cover assembly also includes a rear cover 5 located between the mounting section 19 and the control section 100. The rear cover 5, together with the cover body 1 and the body, forms a mounting cavity, providing a relatively enclosed working environment for the drive module inside the body. On the one hand, this reduces the adverse interference of the external environment on the drive module and helps to improve the working stability of the treatment device. On the other hand, the rear cover 5 and the cover body 1 shield the internal components of the body, preventing the drive module from being exposed to the user's field of vision and helping to optimize the user's sensory experience.

[0100] As a preferred embodiment of this implementation, such as Figure 15As shown, the rear cover 5 has a first part 53 connected to the control unit 100 and a second part 54 connected to the mounting part 19. The first part 53 and the second part 54 are arranged at an angle to form a gap 6. By configuring the rear cover 5 to include the first part 53 and the second part 54, the rear cover 5 can provide a certain degree of support for the control unit 100, reducing the probability of the control unit 100 deforming downward under its own weight or during long-term operation, and providing a more stable working environment for the control screen 1001. In addition, the first part 53 and the second part 54 are arranged at an angle, and a gap 6 is formed between them. When the user needs to move the therapeutic device, he / she can put his / her hand into the gap 6 to lift the therapeutic device, thereby reducing the pressure on the user when moving the therapeutic device.

[0101] As a preferred example in this embodiment, such as Figure 16 As shown, the control unit 100 has a receiving hole 1002 for mounting the control panel 1001, and the first part 53 has a water guiding slope 531 located below the receiving hole 1002. The first part 53 has a water outlet 7 communicating with the outside of the mounting cavity at the low position of the water guiding slope 531.

[0102] The receiving hole 1002 on the control unit 100 provides a mounting position for the control panel 1001, allowing the control panel 1001 to be stably mounted on the control unit 100 through the receiving hole 1002. The humidification tank, as an important component of the humidification therapy device, heats the water inside the tank using a heating element, causing the water to evaporate. The evaporated water vapor is then delivered to the patient's respiratory tract through the breathing tubing to achieve the purpose of humidification therapy. The humidification tank needs to be frequently refilled or its water changed during operation. Since the humidification tank is usually refilled via a suspended water bag, operational issues may arise during the refilling or changing of water. Water splashes or drips onto the top cover assembly, or if the humidification therapy device encounters rain during transport, water droplets may drip downwards and enter the mounting cavity through the assembly gap between the rear cover 2 and the mounting part 11, or between the rear cover 2 and the control part 12. Water droplets seeping into the assembly gaps will fall onto the water-guiding slope 531 under gravity. Because the water-guiding slope 531 extends obliquely and the water outlet 7 is located at the lower position of the water-guiding slope 531, the liquid falling onto the water-guiding slope 531 will continue to slide down the water-guiding slope 531 under gravity and be discharged outside the mounting cavity through the water outlet 7 located at the lower position. This prevents liquid from entering the mounting cavity through the gaps around the receiving hole 1002 and accumulating inside the mounting cavity, which could affect the normal operation of the drive module, thus ensuring the stability of the therapy device's operation.

[0103] Specifically, waterproof foam is provided between the back cover 2 and the control unit 12 or between the back cover 2 and the mounting unit 11.

[0104] As a preferred method in this example, such as Figure 16As shown, the top of the first part 53 is provided with a water-guiding protrusion 532, which cooperates with the upper surface of the first part 53 to form a water-guiding slope 531. The water-guiding protrusion 532 provided at the top of the first part 53 can guide the water droplets falling on the first part 53, guiding these water droplets to move along the extension direction of the water-guiding protrusion 532 and be discharged from the installation cavity through the water outlet 7, thereby preventing the water droplets from moving into the installation cavity through the water-guiding slope 531, which helps to improve the water conductivity of the water-guiding slope 531.

[0105] This application does not limit the location and arrangement of the water inlet 7, and it can adopt any of the following schemes:

[0106] Option 1: As Figure 18 As shown, the water inlet 7 includes a first water inlet 71 located in the middle of the first part 53, and the water guiding protrusion 532 includes a first water guiding section 5321. One end of the first water guiding section 5321 is connected to the first water inlet 71, and the other end extends towards the high position of the water guiding slope 531 on both sides of the first water inlet 71. By setting the first water inlet 71 in the middle of the first part 53, water droplets falling on the first part 53 can converge towards the first water inlet 71 under the action of the water guiding protrusion 532. This reduces the movement length required for water droplets on the first part 53 to exit the mounting cavity, helps to shorten the residence time of water droplets in the mounting cavity, and helps to improve the working stability of the drive module inside the mounting cavity.

[0107] Preferably, such as Figure 18 As shown, the water outlet 7 also includes second water outlets 72 located on both sides of the first part 53. The water guiding protrusion 532 also includes a second water guiding section 5322. One end of the second water guiding section 5322 is connected to the first water guiding section 5321, and the other end extends towards the second water outlet 72. By setting the second water guiding section 5322, the guiding area of ​​the water guiding slope 531 for water droplets falling on the first part 53 is increased, reducing the probability that water droplets are not guided by the water guiding slope 531 and accumulate inside the mounting cavity. In addition, the setting of the second water outlet 72 also provides a new discharge channel for water droplets. When the water seepage inside the mounting cavity is serious and a large number of water droplets enter the mounting cavity, the first water outlet 71 and the second water outlet 72 work together to guide and discharge the water droplets inside the mounting cavity, reducing the probability of water droplets accumulating inside the mounting cavity due to untimely discharge.

[0108] This application does not limit the location of the second water inlet 72 or the structural form of the second water diversion section 5322, which can be as follows: Figure 18 As shown, the second water inlet 72 is located on the side of the first part away from the first water inlet section 5321, and the second water inlet section 5322 gradually extends at an incline from the side closer to the first water inlet section 5321 toward the second water inlet 72; it can also be as follows: Figure 27As shown, the second water inlet 72 is located in the middle of the side of the first part 53. The second water inlet section 5322 is divided into two sections. One section extends inclinedly from the first water inlet section 5321 to the second water inlet 72, and the other section extends inclinedly from the side of the first part 53 away from the first water inlet section 5321 to the second water inlet 72.

[0109] Furthermore, such as Figure 19 As shown, the cover 1 is provided with an installation area 8 that is rotatably connected to the lifting member 2. The second water inlet 72 is located above the installation area 8. There is a water passage gap between the lifting member 2 and the cover 1. The installation area 8 is connected to the outside through the water passage gap.

[0110] The cover 1 is provided with an installation area 8 to facilitate the assembly of the lifting component 2. The second water outlet 72 is located above the installation area 8. A water passage gap is provided between the lifting component 2 and the cover 1. Water discharged from the second water outlet 72 can flow to the installation area 8 under the action of gravity and flow out of the machine body through the water passage gap. This eliminates the need to set up a separate discharge channel for the water discharged from the second water outlet 72, which helps to optimize the structural design of the upper cover assembly.

[0111] Preferably, the cover 1 has a bend in the direction of the mounting cavity at the corresponding mounting area 8, which reduces the space occupied by the lifting member 2 on the external space of the cover 1 and helps to maintain the flatness of the appearance surface of the cover assembly.

[0112] Option 2: Figure 19 , Figure 20 As shown, there are two water inlets 7, distributed on both sides of the first part 53, and the water guiding protrusions 532 extend from the high position of the water guiding slope 531 to the water inlets 7. Setting the number of water inlets 7 to two provides more discharge paths for water droplets on the water guiding slope 531, which helps to reduce the probability of water droplets accumulating in the mounting cavity.

[0113] This solution does not limit the number or location of water inlets; they can be, for example... Figure 19 , Figure 20 As shown, there are two water inlets 7, located at the middle positions on both sides of the first part 53, with the two ends of the side portion of the first part 53 inclined towards the water inlets 7; it can also be as follows: Figure 28 As shown, each side of the first part 53 is provided with two water inlets 7. The water-guiding protrusion 532 is divided into two sections, one section extending along the length of the first part 53 and the other section extending along the width of the first part 53. The water inlets 7 are located at the corner of the water-guiding protrusion 532 and the lowest position of the side of the first part 53, respectively.

[0114] As another preferred embodiment of this implementation, such as Figure 21 , Figure 22As shown, the first part 53 has a first mounting hole 5331, and the cover 1 has a second mounting hole 1011 that aligns with the first mounting hole 5331. The first part 53 is connected to the cover 1 by sequentially inserting mounting parts 9 into the first mounting hole 5331 and the second mounting hole 1011. Preferably, the first mounting hole 5331 and the second mounting hole 1011 have matching internal threads, the mounting part 9 is a stud, and the cover 1 and the rear cover 5 are threadedly connected by the stud.

[0115] As a preferred example in this embodiment, such as Figure 22 As shown, the first part 53 has a mounting boss 533, which is hollow inside to form a first mounting hole 5331. The cover 1 has a positioning protrusion 101, which is hollow inside to form a second mounting hole 1011. The positioning protrusion 101 abuts against the mounting boss 533 to make the first mounting hole 5331 and the second mounting hole 1011 aligned and connected. The installation of the mounting boss 533 and the positioning boss 101 reduces the difficulty of creating the first mounting hole 5331 and the second mounting hole 1011, thus improving the manufacturing efficiency of the cover 1 and the rear cover 5. Furthermore, during the assembly of the rear cover 5 and the cover 1, the assembler only needs to control the mounting boss 533 and the positioning boss 1 to abut against each other to achieve communication between the first mounting hole 5331 and the second mounting hole 1011, eliminating the need for precise alignment of the relative positions of the first mounting hole 5331 and the second mounting hole 1011, and reducing the assembly difficulty of the rear cover 5 and the cover 1. In addition, the lengths of the first mounting hole 5331 and the second mounting hole 1011 can be adjusted by adjusting the lengths of the positioning boss 101 and the mounting boss 533, reducing the thickness requirements of the rear cover 5 and the cover 1, and helping to optimize the structural design of the upper cover assembly.

[0116] As a preferred approach in this example, such as Figure 22As shown, the first part 53 is provided with a first positioning step 534, and the cover 1 is provided with a second positioning step 102 that is adapted to the first positioning step 534. When the first positioning step 534 and the second positioning step 102 are engaged, the first mounting hole 5331 and the second mounting hole 1011 are aligned. The first positioning step 534 and the second positioning step 102 increase the fitting area between the cover 1 and the rear cover 5. When the upper cover assembly is subjected to external force and the cover 1 and the rear cover 5 tend to shift relative to each other, the interlocking first positioning step 534 and the second positioning step 102 can block the relative position of the cover 1 and the rear cover 5 to a certain extent, which helps to ensure the stability of their relative position. On the other hand, when assembling the cover 1 and the rear cover 5, it is only necessary to fit the first positioning step 534 into the second positioning step 102 to achieve the positioning of the positioning protrusion 101 and the mounting protrusion 533, thereby achieving the alignment and communication between the first mounting hole 5331 and the second mounting hole 1011, which helps to improve the assembly speed of the rear cover 5 and the cover 1.

[0117] As a preferred embodiment of this implementation, such as Figure 23 As shown, the second part 54 is provided with a first limiting hole 541, and the upper cover assembly also includes a fixing frame 110 connected to the cover body 1. The fixing frame 110 is provided with a first limiting protrusion 1101, which abuts against the inner wall of the first limiting hole 541. By providing the first limiting hole 541 in the second part 54 and the first limiting protrusion 1101 in the fixing frame 110 respectively, when the rear cover 5 is subjected to external force and has a tendency to move relative to the fixing frame 110, the first limiting protrusion 1101 cooperates with the first limiting hole 541 to limit the displacement of the rear cover 5 and the fixing frame 110. The fixing frame 110 is also connected to the cover body 1, which simultaneously improves the stability of the relative position of the cover body 1 and the rear cover 5.

[0118] As a preferred example in this embodiment, such as Figure 23 As shown, the first limiting protrusion 1101 includes a first column 11011 located within the first limiting hole 541 and a second column 11012 located below the first column 11011. The cross-sectional area of ​​the second column 11012 is larger than that of the first column 11011. The second part 54 is provided with an annular sleeve 542 below the limiting hole, and the second column 11012 abuts against the inner wall of the annular sleeve 542. By setting the first column 11011 with a smaller cross-sectional area than the second column 11012, the first limiting protrusion 1101 can be inserted into the annular sleeve 542 more easily. Furthermore, the first column 11011 abuts against the inner wall of the limiting hole, and the second column 11012 abuts against the inner wall of the annular sleeve 542, achieving a double abutment between the first limiting protrusion 1101 and the limiting hole and the annular sleeve 542, which helps to enhance the stability of the relative position between the rear cover 5 and the fixing bracket 110.

[0119] As a preferred approach in this example, such as Figure 23 As shown, an annular sealing rib 120 is sleeved around the outer periphery of the first column 11011. The annular sealing rib 120 abuts against the inner wall of the annular sleeve 542 and the outer wall of the first column 11011. The annular sealing rib 120 further improves the tightness of the abutment between the first limiting protrusion 1101 and the annular sleeve 542, thereby further enhancing the stability of the relative position between the rear cover 5 and the fixing frame 110.

[0120] As another preferred example under this embodiment, such as Figure 16 , Figure 17 As shown, the second part 54 is provided with a second limiting hole 543 that is offset from the first limiting hole 541, and the fixing frame 110 is also provided with a second limiting protrusion 1102, which abuts against the inner wall of the second limiting hole 543. The setting of the second limiting hole 543 and the second limiting protrusion 1102 further enhances the stability of the relative position between the fixing frame 110 and the rear cover 5. The first limiting hole 541 and the first limiting protrusion 1101, and the second limiting hole 543 and the second limiting protrusion 1102 cooperate to provide great assurance for the stability of the fixing frame 110 and the rear cover 5.

[0121] Preferably, the bottom of the mounting bracket 110 has multiple component mounting positions for mounting the drive module. These mounting positions at the bottom of the mounting bracket 110 provide a mounting platform for the drive module, eliminating the need for a separate mounting component 9 and helping to optimize the structural layout of the upper cover assembly. Furthermore, the mounting bracket 110, in addition to enhancing the connection stability between the rear cover 5 and the cover body 1, further integrates the function of providing mounting positions for the drive module, resulting in a high degree of functional integration and optimizing the structural design of the upper cover assembly.

[0122] Furthermore, such as Figure 24As shown, the bottom of the cover 1 has an opening for the fixing bracket 110 to be inserted from the bottom of the cover 1. The fixing bracket 110 has a guide groove 1103, and the cover 1 has a guide slide 103 extending vertically, which abuts against the inner wall of the guide groove 1103. The opening at the bottom of the cover 1 allows the fixing bracket 110 to be inserted from the bottom of the cover 1. The guide groove 1103 and guide slide 103 eliminate the need for assemblers to perform relative positioning calibration between the fixing bracket 110 and the cover 1; during assembly, only the guide slide 103 and guide groove 1103 need to be aligned, improving assembly efficiency. Furthermore, the guide slide 103 and guide groove 1103 provide motion guidance for the fixing bracket 110 to be inserted into the bottom of the cover 1, preventing jamming between the fixing bracket 110 and the cover 1 due to uneven force applied by the assembler or other factors during assembly, thus reducing the assembly difficulty of the fixing bracket 110.

[0123] As a preferred embodiment of this application, such as... Figure 19 As shown, the top of the mounting part 19 is provided with a water-blocking rib 130 arranged circumferentially, and the water-blocking rib 130 extends vertically and abuts against the inner wall of the rear cover 5.

[0124] The water-blocking rib 130 can prevent water droplets from entering the body through the gap between the rear cover 5 and the mounting part 19, reducing the probability of water droplets entering the mounting cavity and helping to improve the waterproof effect of the top cover assembly.
