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

[0022] 1. The upper cover assembly of the present application includes a cover body and a lifting member movably connected to the cover body. When the therapeutic device is not being transported, the lifting member is located in the storage position and will not occupy too much of the external space of the upper cover assembly. When the therapeutic device needs to be transported, the lifting member is switched to the lifting position, and the user lifts the grip portion so that the cover body and the body are lifted up by the connecting portion, and then the user can transport the therapeutic device by holding the lifting member with one hand. This saves the user from having to lift the therapeutic device with both hands for transportation, which helps to improve the user experience. In addition, the lifting member is rotatably connected to the cover body and realizes the switching of the lifting member between the storage position and the lifting position by rotating in the first rotation direction and the second rotation direction respectively, which can increase the switching efficiency of the lifting member between the lifting position and the storage position, and the user can easily adjust the position of the lifting member, which helps to optimize the user experience; on this basis, when the lifting member is in the lifting position, the projection of the gripping part in the vertical direction coincides with the center of gravity of the body, so that when the user lifts the therapeutic device to move, the position where the user applies force to the lifting member and the center of gravity of the body are located in the same vertical plane, which helps to increase the stability of the therapeutic device during transportation, avoids the unbalanced torque of the body caused by the misalignment of the lifting force application point and the center of gravity of the body, thereby avoiding the shaking or even tipping of the therapeutic device due to the unbalanced torque. At the same time, it helps to reduce the attention that the user needs to pay to the therapeutic device when lifting the therapeutic device and walking, avoids the user from applying extra energy to adjust the position of the therapeutic device to prevent it from flipping, so that the user can pay more attention to walking itself, which helps to improve the transportation efficiency of the therapeutic device.

[0023] 2. As a preferred embodiment of the present application, the storage platform arranged along the circumference of the cover body provides a placement position for the lifting member in the storage position, so that when the therapeutic device is working normally, the lifting member can occupy a smaller external space of the cover body, which is conducive to the miniaturization of the therapeutic device; on this basis, the outer surface of the lifting member is flush with the outer surface of the cover, so that the outer surface of the upper cover assembly has a stronger integrity, and there will be no obvious misalignment at the joint between the lifting member and the cover body, 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 the present application, by providing a limiting protrusion and a first limiting portion having a first stop surface, when the user holds the lifting member to drive the therapeutic device to walk, the lifting member can be stably placed in the lifting position under the cooperation of the first stop surface and the first limiting portion, thereby ensuring the stability of the center of gravity of the body; when the user applies uneven force to the lifting member due to swaying while walking, the lifting member will not easily rotate along the second rotation direction under the cooperation of the first stop surface and the first limiting portion, thereby providing a guarantee for the stability of the lifting therapeutic device.

[0025] 4. As a preferred embodiment of the present application, the arc-shaped guide surface guides the rotating end of the lifting part to move toward the first stop surface, so that the lifting part switches from the storage position to the working position more smoothly; in addition, the setting of the arc-shaped guide surface makes it possible for the lifting part to produce a certain damping feeling when it contacts the arc-shaped guide surface during the rotation process along the first rotation direction, thereby giving the user a certain force feedback, so that the user can know that the lifting part is close to the lifting position. When the lifting part is separated from the arc-shaped guide surface and abuts against the first stop surface, the damping feeling applied to the user by the arc-shaped guide surface through the lifting part disappears, and the user can know that the lifting part has reached the lifting position through the force change, and thus stops rotating. That is, by setting the arc-shaped guide surface, a guiding effect is provided for the rotation of the lifting part along the first direction, and force feedback can also be given to the user, so that the user can know whether the lifting part has rotated to the lifting position without observing the position of the lifting part.

[0026] 5. As a preferred embodiment of the present application, the setting of the tactile protrusion and the groove makes the lifting member have a more obvious setback when passing through the two in sequence, thereby giving the user force feedback, letting the user know that the lifting member has been rotated to the arc-shaped guide surface, and the user can increase the force and rotate it to a certain degree to reach the lifting position.

[0027] 6. As a preferred embodiment of the present application, a limit plate is provided between the connecting part and the cover body. When the rotating part and the rotating hole on the connecting part are installed, the limit plate can limit the rotating part from falling out of the rotating hole, thereby providing a guarantee for the installation stability of the rotating part in the rotating hole, thereby ensuring the connection stability between the lifting part and the cover body.

[0075] like Figure 1 , Figure 2 As shown, an upper cover assembly applied to a respiratory humidification therapy device is installed on the body of the respiratory humidification therapy device, the upper cover assembly includes a cover body 1, the upper cover assembly also includes a lifting member 2 movably connected to the cover body 1, the lifting member 2 includes a gripping portion 21 and a connecting portion 22 rotatably connected to the cover body 1, the lifting member 2 has a lifting position and a storage position, the lifting member 2 can be switched from the storage position to the lifting position along a first rotation direction, and can be switched from the lifting position to the storage position along a second rotation direction; when the lifting member 2 is in the lifting position, the projection of the gripping portion 21 along the vertical direction coincides with the center of gravity of the body.

[0076] Figure 1 The lifting member 2 is in the lifting position, Figure 2 The lifting member 2 is in the storage position, Figure 2The arrow X indicates the first rotation direction, and the arrow Y indicates the second rotation direction. The upper cover assembly of the present 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 located in the storage position and does not occupy too much external space of the upper cover assembly; when the therapeutic device needs to be transported, the lifting member 2 switches to the lifting position, and the user lifts the gripping portion 21 so that the cover body 1 and the body are lifted up by the connecting portion 22, and then the user can transport the therapeutic device by holding the lifting member 2 with one hand; the user is saved from the operation of lifting the therapeutic device with both hands for transportation, which helps to improve the user experience. In addition, the lifting member 2 is rotatably connected to the cover body 1 and realizes the switching of the lifting member 2 between the storage position and the lifting position by rotating along the first rotation direction and the second rotation direction respectively, which can increase the switching efficiency of the lifting member 2 between the lifting position and the storage position, and the user can easily adjust the position of the lifting member 2, which helps to optimize the user experience; on this basis, Fig.25 and Fig.26 As shown, the position of the five-pointed star is the position of the center of gravity of the machine. When the lifting member 2 is in the lifting position, the projection of the gripping portion 21 along the vertical direction coincides with the center of gravity of the body, so that when the user lifts the therapeutic device to move, the position where the user applies force to the lifting member 2 is in the same vertical plane as the center of gravity of the body, which helps to increase the stability of the therapeutic device during transportation, avoids the unbalanced torque of the body caused by the misalignment of the lifting force point and the center of gravity of the body, and thus prevents the therapeutic device from shaking or even tipping over due to the unbalanced torque. At the same time, it helps to reduce the attention that the user needs to pay to the therapeutic device when lifting the therapeutic device to walk, avoids the user from applying extra energy to adjust the position of the therapeutic device to prevent it from flipping, and allows the user to pay more attention to walking itself, which helps to improve the transportation efficiency of the therapeutic device.

[0077] It should be pointed out that when the lifting member 2 is in the lifting position, the gripping portion 21 has a certain width along the horizontal direction. Therefore, as long as the projection of the gripping portion 21 along the vertical direction covers the center of gravity of the fuselage, the projection of the gripping portion 21 along the vertical direction can be regarded as coinciding with the center of gravity of the fuselage.

[0078] As a preferred implementation of the present application, Figure 1As shown, the cover body 1 is provided with a storage platform 11 arranged along its circumference. 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 body 1. The storage platform 11 arranged along the circumference of the cover body 1 provides a placement position for the lifting member 2 in the storage position, so that when the therapeutic device works normally, the lifting member 2 can occupy a smaller external space of the cover body 1, which is conducive to the miniaturization of the therapeutic device; on this basis, the outer surface of the lifting member 2 is flush with the outer surface of the cover body 1, so that the outer surface of the upper cover assembly is more integrated, and there is no obvious misalignment at the abutment between the lifting member 2 and the cover body 1, which helps to improve the aesthetics of the upper cover assembly and optimize the user's visual experience.

[0079] Preferably, if Figure 1 As shown, the upper cover assembly also includes a rear cover 5 located on the rear side of the cover body 1, and the rear cover 5 and the cover body 1 are staggered to form a storage platform 11 between the two; when the lifting member 2 is in the storage position, the outer surface of one side of the lifting member 2 is flush with the outer surface of the cover body 1, and the outer surface of the other side of the lifting member 2 is flush with the outer surface of the back cover 5.

[0080] As a preferred implementation of the present application, Figures 3 to 6 As shown, the cover body 1 is provided with a first limiting portion 12, the first limiting portion 12 has a first stop surface 121, and the connecting portion 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 limit the rotation of the connecting portion 22 along the second rotation direction. By providing the limiting protrusion 221 and the first limiting portion 12 having the first stop surface 121, when the user holds the lifting member 2 to drive the therapeutic device to walk, 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 portion 12, thereby ensuring the center of gravity stability of the body; when the user sways and shakes while walking, resulting in uneven force on the lifting member 2, the lifting member 2 will not easily rotate along the second rotation direction under the cooperation of the first stop surface 121 and the first limiting portion 12, thereby providing a guarantee for the stability of the lifting therapeutic device.

[0081] As a preferred embodiment of this implementation, Figure 4As shown, the first limiting portion 12 is further provided with an arc-shaped guide surface 122, and along the first rotation direction, one end of the arc-shaped guide surface 122 is connected to the cover body 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 portion to move toward the first stop surface 121, so that the lifting member 2 switches from the storage position to the working position more smoothly; in addition, the setting of the arc-shaped guide surface 122 makes it possible for the lifting member 2 to produce a certain damping feeling when it contacts the arc-shaped guide surface 122 during the rotation process along the first rotation direction, thereby giving the user a certain force feedback, so that the user can know that the lifting member 2 is close to the lifting position. When the lifting member 2 is separated from the arc-shaped guide surface 122 and abuts against the first stop surface 121, the damping feeling applied to the user by the arc-shaped guide surface 122 through the lifting member 2 disappears, and the user can know that the lifting member 2 has reached the lifting position through the force change, and thus stops rotating. That is, by providing the arc-shaped guide surface 122, a guiding effect is provided for the rotation of the lifting member 2 along the first direction, and force feedback can also be given to the user, so that the user can know whether the lifting member 2 has rotated to the lifting position without observing the position of the lifting member 2.

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

[0083] As a preferred example under this embodiment, Figure 4 As shown, the cover body 1 is further provided with a tactile protrusion 13 adjacent to the first limiting portion 12, and a groove 14 is formed between the tactile protrusion 13 and the arc-shaped guide surface 122. The setting of the tactile protrusion 13 and the groove 14 makes the lifting member 2 have a relatively obvious setback when passing through the two in sequence, thereby giving the user force feedback, letting the user know that the lifting member 2 has rotated to the arc-shaped guide surface 122, and increasing the force and rotating to a certain extent to reach the lifting position.

[0084] As a preferred implementation of the present application, Figure 4 As shown, the cover body 1 is further provided with a second limiting portion 15, and the second limiting portion 15 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 portion 22 to limit the rotation of the connecting portion 22 along the first rotation direction. The second stop surface 151 is provided to limit the lifting member 2 in the lifting position. When the user rotates the lifting member 2 along the first rotation direction until the lifting member 2 rotates to the lifting position, the second stop surface 151 limits the continued rotation of the lifting member 2. The user can know the position state of the lifting member 2 through force feedback, thereby optimizing the user's use experience.

[0085] The present application does not limit the rotational connection method between the lifting member 2 and the cover body 1, and it can adopt any one of the following embodiments:

[0086] Implementation method 1: Figure 4 , Figure 8 As shown, the connecting portion 22 is provided with a rotating member 222, and the cover body 1 is provided with a rotating hole 16 adapted to the rotating member 222. The connecting portion 22 is rotatably connected to the cover body 1 through the rotating member 222, and further includes a limiting plate 3 provided between the connecting portion 22 and the cover body 1, and the limiting plate 3 abuts against the rotating member 222 to limit the rotating member 222 from escaping from the rotating hole 16. A limiting plate 3 is provided between the connecting portion 22 and the cover body 1. When the rotating member 222 on the connecting portion 22 and the rotating hole 16 are installed, the limiting plate 3 can limit the rotating member 222 from escaping from the rotating hole 16, thereby providing a guarantee for the installation stability of the rotating member 222 in the rotating hole 16, thereby ensuring the connection stability of the lifting member 2 and the cover body 1.

[0087] It should be pointed out that the limiting plate 3 and the rotating member 222 mentioned in the present embodiment are against each other, which does not mean that the two are in close contact, but that there is a certain gap between them. When the rotating member 222 works normally, the rotating member 222 does not contact the limiting plate 3. When the rotating member 222 is affected by external force or other factors and its position is shifted, the limiting plate 3 prevents the rotating member 222 from further dislocating, so as to maintain the normal rotation of the rotating member 222.

[0088] As a preferred embodiment of this implementation, Figure 4 , Figure 8 As shown, the limiting plate 3 is provided with a first fixing hole, the cover body 1 is provided with a second fixing hole, and the limiting plate 3 is connected to the cover body 1 through a fixing member that penetrates the first fixing hole and the second fixing hole in sequence; the rotating member 222 includes a rotating portion 2221 located in the rotating hole 16 and a rotating shaft 2222 that connects the rotating portion 2221 with the connecting portion 22, and the limiting plate 3 is further provided with a through hole 31 through which the rotating shaft 222 penetrates. The connection between the limiting plate 3 and the cover body 1 is achieved by sequentially penetrating the fixing member of the first fixing hole and the second fixing hole, which helps to increase the installation stability of the limiting plate 3, so that it can stably limit the escape of the rotating portion 2221 from the rotating hole 16; and the setting of the through hole 31 enables the limiting plate 3 to limit the rotating portion 2221 while not affecting the assembly of the rotating portion 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, and it can adopt any one of the following examples:

[0090] Example 1: Figure 4 As shown, the area of ​​the penetration hole 31 is smaller than that of the rotating part 2221, and the penetration hole 31 has an avoidance opening 311, so that the rotating shaft 2222 enters the penetration hole 31 through the avoidance opening 311. In this example, when assembling the rotating member 222 and the limiting plate 3, the rotating member 222 is installed first, and after the rotating part 2221 is installed in the rotating hole 16, the limiting plate 3 is installed, and the avoidance opening 311 of the limiting plate 3 is aligned with the rotating shaft 2222 and the limiting plate 3 is pushed, and after the rotating shaft 2222 is located in the penetration hole 31, the rotating part 2221 abuts against the limiting plate 3.

[0091] Example 2: If Fig. 9 , Fig.10 As shown, the shape of the penetration hole 31 is adapted to the rotating part 2221 for the penetration of the rotating part 2221, and the limiting plate 3 has a first position for aligning the penetration hole 31 with the rotating hole 16 and a second position for misaligning the penetration hole 31 with the rotating hole 16. When the limiting plate 3 is located at the second position, the first fixing hole is aligned with the second fixing hole, and the penetration hole 31 is misaligned with the rotating hole 16 to limit the rotating part 2221 from slipping out. Fig.10 The limit plate 3 shown in the figure is in the second position. In this example, the limit plate 3 is first assembled and placed in the first position. Then, the rotating part 2221 and the rotating shaft 2222 are sequentially penetrated through the rotating hole 16. After the rotating part 2221 is located in the rotating hole 16, the limit plate 3 is switched from the first position to the second position. At this time, the penetrated hole 31 is misaligned with the rotating hole 16, and the rotating part 2221 located in the rotating hole 16 cannot escape through the penetrated hole 31, thereby realizing the limiting of the rotating part 2221 by the limit plate 3.

[0092] Preferably, if Fig.10 As shown, the cover body 1 is provided with a positioning protrusion 17, 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, 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 is abutted against the first mating surface, when the limiting plate 3 is in the second position, the second positioning surface is abutted against the second mating surface.

[0093] The setting of the positioning protrusion 17 and the positioning groove 32 provides a positioning function for the limit plate 3. When the rotating member 222 is installed, the limit plate 3 remains stable under the abutment of the first positioning surface and the second positioning surface so as to penetrate the rotating part 2221 and the rotating shaft 2222; when the rotating member 222 is installed, the limit plate 3 is pushed until the second positioning surface abuts against the second matching surface, thereby stabilizing the limit plate 3 at a position where the avoidance hole and the rotating hole 16 are misaligned.

[0094] Implementation method 2: Figure 11-Figure 14 As shown, the connecting portion 22 is provided with a rotating piece 222, and the cover body 1 is provided with a rotating hole 16 adapted to the rotating piece 222. The connecting portion 22 is rotatably connected to the cover body 1 through the rotating piece 222. The rotating piece 222 includes a rotating portion 2221 located in the rotating hole 16 and a rotating shaft 2222 connecting the rotating portion 2221 with the connecting portion 22. The cover body 1 is provided with a limiting protrusion 18 on the outside of the rotating hole 16, and the connecting portion 22 is provided with a limiting groove 223; when the limiting groove 223 is aligned with the limiting protrusion 18, the rotating portion 2221 can enter the rotating hole 16 or detach from the rotating hole 16, and when the limiting groove 223 is misaligned with the limiting protrusion 18, the rotating protrusion abuts against the connecting portion 22 to limit the rotating portion 2221 from detaching from the rotating hole 16.

[0095] By setting a limiting protrusion 18 and a limiting groove 223, the rotating part 2221 can enter or escape from the rotating hole 16 only when the limiting groove 223 is aligned with the limiting protrusion 18. When the limiting groove 223 and the limiting protrusion 18 are misaligned, the rotating part 2221 cannot escape from the rotating hole 16 due to the stopping effect of the limiting protrusion 18, thereby providing a guarantee for the installation stability of the rotating part 2221 in the rotating hole 16, thereby ensuring the connection stability of the lifting member 2 and the cover body 1.

[0096] As a preferred embodiment of this implementation, Fig.13 , Fig.14 As shown, the upper cover assembly also includes a rear cover 5, which includes a limit stop arm 51 located between the rotating part 2221 and the connecting part 22, and the limit stop arm 51 is provided with an avoidance groove 511 for the rotating shaft 2222 to pass through. The limit stop arm 51 can stop the rotating part 2221 to limit the rotating part 2221 from disengaging from the rotating hole 16. Because when the lifting member 2 is rotated to make the limiting groove 223 and the limiting protrusion 221 align, the rotating part 2221 still has the risk of escaping from the rotating hole 16; therefore, by setting the back cover 5 and setting the limiting stop arm 51 on the back cover 5, when the limiting groove 223 and the limiting protrusion 221 are aligned, and the lifting member 2 is affected by external force or other factors so that the rotating part 2221 has the tendency to escape from the rotating hole 16, the limiting stop arm 51 can act as a limiting stop for the rotating part 2221, thereby eliminating the risk of the rotating part 2221 escaping from the rotating hole 16.

[0097] Preferably, one of the cover body 1 and the limit stop arm 51 is provided with a mounting slot, and the other is provided with a mounting buckle located in the mounting slot, and the cover body 1 and the rear cover 5 are engaged with each other through the mounting slot and the mounting buckle. The detachable connection between the cover body 1 and the limit stop arm 51 is achieved through the mounting buckle and the mounting slot, which, on the one hand, makes the installation of the limit stop arm 51 simpler and helps to improve the installation speed of the rear cover 5; on the other hand, it is convenient to remove the limit stop arm 51 from the cover body 1 for inspection or replacement.

[0098] As a preferred implementation of the present application, Fig.15 As shown, the cover body 1 has a mounting portion 19 and a control portion 100, the mounting portion 19 is mounted on the fuselage, the control portion 100 is arranged at an angle to the mounting portion 19 and has a control screen 1001 extending obliquely; the upper cover assembly also includes a back cover 5 located between the mounting portion 19 and the control portion 100, the back cover 5 cooperates with the cover body 1 and the fuselage to form a mounting cavity for installing the drive module.

[0099] The control unit 100 and the mounting unit 19 are arranged at an angle, so that the control screen 1001 mounted on the control unit 100 extends obliquely, that is, the control screen 1001 is at a certain angle to the horizontal plane. The user only needs to stand in front of the therapeutic device to intuitively obtain the information on the control screen 1001 and can operate the control screen 1001 at the front of the body. In this way, when the therapeutic device is placed at a certain distance from the operator, such as in the middle of the desktop, the user does not need to move the therapeutic device, and can observe and operate the control screen 1001 at the edge of the desktop, thereby optimizing the user experience. In addition, the upper cover assembly also includes a back cover 5 located between the mounting portion 19 and the control portion 100. The back cover 5 cooperates with the cover body 1 and the fuselage to form a mounting cavity, providing a relatively closed working environment for the driving module inside the fuselage. On the one hand, it reduces the adverse interference of the external environment on the driving module, which helps to improve the working stability of the therapeutic device; on the other hand, the back cover 5 and the cover body 1 have a shielding effect on the internal components of the fuselage, avoiding exposure of the driving module to the user's field of view, which helps to optimize the user's sensory experience.

[0100] As a preferred embodiment of this implementation, Fig.15As shown, the rear cover 5 has a first portion 53 connected to the control unit 100 and a second portion 54 connected to the mounting portion 19, and the first portion 53 and the second portion 54 are arranged at an angle to form a gap 6. The rear cover 5 is arranged to include the first portion 53 and the second portion 54, so that the rear cover 5 can play a certain supporting role for the control unit 100, reduce the probability of the control unit 100 being deformed downward under the action of its own weight or during long-term operation and use, and provide a relatively stable working environment for the control screen 1001; on this basis, the first portion 53 and the second portion 54 are arranged at an angle, and a gap 6 is formed between the two. When the user needs to carry the therapeutic device, he can put his hand into the gap 6 to lift the therapeutic device, thereby reducing the transportation pressure of the therapeutic device by the user.

[0101] As a preferred example under this embodiment, Fig.16 As shown, the control part 100 is provided with a receiving hole 1002 for installing the control panel 1001, and the first part 53 has a water guide slope 531 located below the receiving hole 1002. The first part 53 is provided with a water outlet 7 connected to the outside of the installation cavity at a low position of the water guide slope 531.

[0102] The receiving hole 1002 opened on the control unit 100 provides an installation position for the control screen 1001, so that the control screen 1001 can be stably installed on the control unit 100 through the receiving hole 1002. The humidification tank is an important component of the humidification therapy device. The humidification tank heats the water in the tank through the heating element to evaporate the water and transmit the evaporated water vapor to the patient's respiratory tract through the breathing tube to achieve the purpose of humidification therapy. The humidification tank needs to be frequently added or replaced with water during operation, and the humidification tank is usually added with water through a hanging water bag. Therefore, during the process of adding or replacing water, it may be caused by operational problems. When water splashes or drips onto the upper cover assembly, or when the respiratory humidification therapy device encounters rain during transportation, water droplets may drip downward and enter the interior of the installation cavity through the assembly gap between the rear cover 2 and the installation portion 11 or the assembly gap between the rear cover 2 and the control portion 12; water droplets that penetrate through the assembly gap will fall onto the water guiding slope 531 under the action of gravity. Since the water guiding slope 531 extends obliquely and the water outlet 7 is located at the low position of the water guiding slope 531, the liquid that falls onto the water guiding slope 531 will continue to slide along the water guiding slope 531 under the action of gravity and be discharged from the outside of the installation cavity through the water outlet 7 located at the low position. Preventing liquid from entering the interior of the installation cavity through the gap at the edge of the receiving hole 1002 and accumulating inside the installation cavity to affect the normal operation of the drive module provides a guarantee for the working stability of the therapeutic device.

[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, Fig.16As shown, a water guide convex strip 532 is provided on the top of the first part 53, and the water guide convex strip 532 cooperates with the upper surface of the first part 53 to form a water guide slope 531. The water guide convex strip 532 provided on the top of the first part 53 can guide the water droplets dripping on the first part 53, guide these water droplets to move along the extension direction of the water guide convex strip 532 and be discharged from the installation cavity through the water outlet 7, thereby preventing the water droplet water guide slope 531 from moving into the installation cavity, which helps to improve the water conductivity of the water guide slope 531.

[0105] The present application does not limit the position and arrangement of the water outlet 7, and any of the following solutions may be adopted:

[0106] Option 1: If Fig.18 As shown, the water outlet 7 includes a first water outlet 71 located in the middle of the first part 53, and the water guide convex strip 532 includes a first water guide section 5321. One end of the first water guide section 5321 is connected to the first water outlet 71, and the other end extends to the high position of the water guide slope 531 on both sides of the first water outlet 71. The first water outlet 71 is arranged in the middle of the first part 53, so that the water droplets dripping on the first part 53 can be gathered toward the first water outlet 71 under the action of the water guide convex strip 532, which reduces the movement length required for the water droplets on the first part 53 to be discharged from the installation cavity, which helps to shorten the residence time of the water droplets in the installation cavity and helps to improve the working stability of the driving module inside the installation cavity.

[0107] Preferably, if Fig.18 As shown, the water outlet 7 also includes a second water outlet 72 located on both sides of the first part 53, and the water guide convex strip 532 also includes a second water guide section 5322, one end of the second water guide section 5322 is connected to the first water guide section 5321, and the other end extends toward the second water outlet 72. By setting the second water guide section 5322, the guiding area of ​​the water guide slope 531 for water droplets dripping on the first part 53 is increased, and the probability that the water droplets are not guided by the water guide slope 531 and accumulate inside the installation cavity is reduced. In addition, the setting of the second water outlet 72 also provides a new discharge channel for the water droplets. When the water seepage in the installation cavity is serious and a large number of water droplets enter the installation cavity, the first water outlet 71 cooperates with the second water outlet 72 to guide the water droplets in the installation cavity to be discharged, thereby reducing the probability of the accumulation of water droplets in the installation cavity due to untimely discharge.

[0108] The present application does not limit the position of the second water outlet 72 and the structure of the second water diversion section 5322, which can be as follows: Fig.18 As shown, the second water outlet 72 is located on the side of the first portion away from the first water diversion section 5321, and the second water diversion section 5322 gradually extends from the side close to the first water diversion section 5321 to the second water outlet 72; it can also be as shown in Fig. 27As shown, the second water outlet 72 is located in the middle position of the side of the first part 53, and the second water diversion section 5322 is divided into two sections, one section extends obliquely from the first water diversion section 5321 to the second water outlet 72, and the other section extends obliquely from the side of the first part 53 away from the first water diversion section 5321 to the second water outlet 72.

[0109] Furthermore, if Fig.19 As shown, the cover body 1 is provided with an installation area 8 rotatably connected to the lifting member 2, the second water outlet 72 is located above the installation area 8, there is a water gap between the lifting member 2 and the cover body 1, and the installation area 8 is connected to the outside through the water gap.

[0110] An installation area 8 is provided on the cover body 1 to facilitate the assembly of the lifting member 2, and the second water outlet 72 is located above the installation area 8. A water gap is provided between the lifting member 2 and the cover body 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 fuselage through the water gap, eliminating the operation of setting 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 body 1 is provided with a bend toward the installation cavity at the corresponding installation area 8, which reduces the occupation of the external space of the cover body 1 by the lifting member 2 and helps to maintain the flatness of the appearance surface of the upper cover assembly.

[0112] Option 2: If Fig.19 , Fig. 20 As shown, there are two water outlets 7 distributed on both sides of the first portion 53, and the water guide convex strips 532 extend from the high position of the water guide slope 531 to the water outlet 7. Setting the number of water outlets 7 to two provides more discharge paths for water droplets on the water guide slope 531, which helps to reduce the probability of water droplets accumulating in the installation cavity.

[0113] This solution does not limit the number and location of the water outlets, which can be as follows: Fig.19 , Fig. 20 As shown, there are two water outlets 7, which are respectively located in the middle of both sides of the first portion 53, and both ends of the side of the first portion 53 are inclined toward the water outlet 7; it can also be as shown in Fig.28 As shown, two water outlets 7 are provided on each side of the first portion 53, and the water diversion ridge 532 is divided into two sections, one section extends along the length direction of the first portion 53, and the other section extends along the width direction of the first portion 53. The water outlets 7 are respectively located at the corners of the water diversion ridge 532 and the lowest position of the side of the first portion 53.

[0114] As another preferred embodiment of this embodiment, Fig.21 , Fig. 22As shown, the first part 53 is provided with a first mounting hole 5331, the cover body 1 is provided with a second mounting hole 1011 aligned with the first mounting hole 5331, and the first part 53 is connected to the cover body 1 by inserting the mounting member 9 into the first mounting hole 5331 and the second mounting hole 1011 in sequence. Preferably, the first mounting hole 5331 and the second mounting hole 1011 are provided with matching internal threads, the mounting member 9 is a stud, and the cover body 1 and the rear cover 5 are threadedly connected through the stud.

[0115] As a preferred example under this embodiment, Fig. 22 As shown, the first portion 53 is provided with a mounting boss 533, the mounting boss 533 is hollow inside to form a first mounting hole 5331, the cover body 1 is provided with a positioning boss 101, the positioning boss 101 is hollow inside to form a second mounting hole 1011, the positioning boss 101 abuts against the mounting boss 533 to align and connect the first mounting hole 5331 with the second mounting hole 1011. The provision of the mounting boss 533 and the positioning boss 101, on the one hand, reduces the difficulty of opening the first mounting hole 5331 and the second mounting hole 1011, which helps to improve the manufacturing efficiency of the cover body 1 and the back cover 5; on the other hand, when assembling the back cover 5 and the cover body 1, the assembler only needs to control the mounting boss 533 and the positioning boss 101 to abut against each other to achieve the connection between the first mounting hole 5331 and the second mounting hole 1011, which saves the assembler the operation of accurately aligning the relative positions of the first mounting hole 5331 and the second mounting hole 1011, thereby reducing the difficulty of assembling the back cover 5 and the cover body 1; in addition, the length of the first mounting hole 5331 and the second mounting hole 1011 can be adjusted by adjusting the length of the positioning boss 101 and the mounting boss 533, thereby reducing the thickness requirement for the back cover 5 and the cover body 1, thereby helping to optimize the structural design of the upper cover assembly.

[0116] As a preferred method in this example, Fig. 22As shown, the first portion 53 is provided with a first positioning step 534, and the cover body 1 is provided with a second positioning step 102 adapted to the first positioning step 534. When the first positioning step 534 is engaged with the second positioning step 102, the first mounting hole 5331 is aligned with the second mounting hole 1011. The provision of the first positioning step 534 and the second positioning step 102, on the one hand, increases the engagement area between the cover body 1 and the back cover 5. When the upper cover assembly is subjected to external force and the cover body 1 and the back cover 5 tend to be relatively displaced, the mutually engaged first positioning step 534 and the second positioning step 102 can block the relative position of the cover body 1 and the back cover 5 to a certain extent, thereby helping to ensure the stability of the relative position of the two. On the other hand, when assembling the cover body 1 and the back cover 5, it is only necessary to engage the first positioning step 534 with the second positioning step 102 to achieve the positioning of the positioning boss 101 and the mounting boss 533, thereby achieving the alignment and connection between the first mounting hole 5331 and the second mounting hole 1011, thereby helping to increase the assembly rate of the back cover 5 and the cover body 1.

[0117] As a preferred embodiment of this implementation, Fig.23 As shown, the second portion 54 is provided with a first limiting hole 541, and the upper cover assembly further includes a fixing frame 110 connected to the cover body 1, and the fixing frame 110 is provided with a first limiting convex column 1101, and the first limiting convex column 1101 abuts against the inner wall of the first limiting hole 541. By respectively providing the first limiting hole 541 on the second portion 54 and the first limiting convex column 1101 on the fixing frame 110, when the rear cover 5 is subjected to an external force and has a tendency to be relatively displaced with the fixing frame 110, the first limiting convex column 1101 cooperates with the first limiting hole 541 to limit the displacement of the rear cover 5 and the fixing frame 110, and the fixing frame 110 is connected to the cover body 1, that is, the stability of the relative position of the cover body 1 and the rear cover 5 is simultaneously improved.

[0118] As a preferred example under this embodiment, Fig.23 As shown, the first limiting boss 1101 includes a first column 11011 located in 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 the cross-sectional area of ​​the first column 11011, and the second portion 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 providing the first column 11011 having a smaller cross-sectional area than the second column 11012, the first limiting boss 1101 can be more easily inserted into the annular sleeve 542, and 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, so that the first limiting boss 1101 is double-abutted against 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 frame 110.

[0119] As a preferred method in this example, Fig.23 As shown, an annular sealing rib 120 is sleeved on the outer periphery of the first column 11011, and the annular sealing rib 120 is respectively in contact with the inner wall of the annular sleeve 542 and the outer wall of the first column 11011. The provision of the annular sealing rib 120 further improves the contact tightness between the first limiting protrusion 1101 and the annular sleeve 542, thereby further enhancing the stability of the relative position of the rear cover 5 and the fixing frame 110.

[0120] As another preferred example under this embodiment, Fig.16 , Fig.17 As shown, the second portion 54 is provided with a second limiting hole 543 that is staggered with the first limiting hole 541, and the fixing frame 110 is further provided with a second limiting convex column 1102, and the second limiting convex column 1102 abuts against the inner wall of the second limiting hole 543. The arrangement of the second limiting hole 543 and the second limiting convex column 1102 further enhances the stability of the relative position of the fixing frame 110 and the back cover 5, and the first limiting hole 541 cooperates with the first limiting convex column 1101, and the second limiting hole 543 cooperates with the second limiting convex column 1102, which provides great guarantee for the stability of the fixing frame 110 and the back cover 5.

[0121] Preferably, a plurality of component installation positions are provided at the bottom of the fixing frame 110, and the component installation positions are used to install the drive module. The component installation positions provided at the bottom of the fixing frame 110 provide a mounting platform for the drive module, eliminating the need to separately provide the mounting member 9 for the drive module, and helping to optimize the structural layout of the upper cover assembly. At the same time, the fixing frame 110, on the basis of having the function of enhancing the connection stability between the rear cover 5 and the cover body 1, further integrates the function of providing a mounting position for the drive module, with a high degree of functional integration, and optimizes the structural design of the upper cover assembly.

[0122] Furthermore, if Fig.24As shown, the bottom of the cover body 1 is provided with an opening for the fixing frame 110 to be embedded from the bottom of the cover body 1, the fixing frame 110 is provided with a guide groove 1103, and the cover body 1 is provided with a guide slide 103 extending in the vertical direction, and the guide slide 103 abuts against the inner wall of the guide groove 1103. The opening is provided at the bottom of the cover body 1 so that the fixing frame 110 can be installed from the bottom of the cover body 1, and the setting of the guide groove 1103 and the guide slide 103, on the one hand, saves the assembly personnel from the operation of relative position calibration of the fixing frame 110 and the cover body 1, and only needs to align the guide slide 103 with the guide groove 1103 during assembly, which helps to improve the assembly efficiency; on the other hand, the setting of the guide slide 103 and the guide groove 1103 provides a motion guide for the fixing frame 110 to be embedded into the bottom of the cover body 1, avoiding the occurrence of jamming between the fixing frame 110 and the cover body 1 due to uneven force applied by the assembly personnel or other factors during the assembly of the fixing frame 110, which helps to reduce the assembly difficulty of the fixing frame 110.

[0123] As a preferred implementation of this application. Fig.19 As shown, a water retaining rib 130 is provided on the top of the mounting portion 19 and is circumferentially arranged therearound. The water retaining rib 130 extends in the vertical direction and abuts against the inner wall of the rear cover 5 .

[0124] The water retaining rib 130 can stop water drops entering the interior of the machine body from the gap between the rear cover 5 and the mounting portion 19, thereby reducing the probability of water drops entering the mounting cavity and helping to improve the waterproof effect of the upper cover assembly.
