Description

Technical Field

[0001] This application belongs to the field of medical device technology, specifically relating to a portable respiratory therapy device. Background Technology

[0002] Ventilators and other respiratory therapy equipment are used to assist patients with breathing difficulties or those unable to breathe independently. With advancements in technology and improved living standards, respiratory therapy equipment is gradually moving from hospitals and clinics into homes, allowing users to use it independently at home. Consequently, traditional large-scale respiratory therapy equipment used in hospitals, due to its large size and high cost, is increasingly unable to meet the needs of home use.

[0003] Therefore, in recent years, more and more miniaturized and portable respiratory therapy devices have appeared on the market. Some respiratory therapy devices can even be held with one hand, making them more convenient for users to use or carry around. They are also relatively inexpensive, reducing the financial burden on users.

[0004] However, the internal space layout of miniaturized respiratory therapy equipment is very compact. In order to facilitate the installation and layout of components such as blowers and air ducts, the main unit's outer shell usually consists of multiple parts, which are assembled together to form an installation cavity and constitute the outer surface of the main unit. For example, the main unit shell of some ventilators consists of two parts: an upper shell and a lower shell, which are spliced ​​and fixed together.

[0005] However, in existing technologies, screws or clips are generally used to fasten the various parts of the outer casing when assembling and fixing them together. For screw fastening, multiple screws are often used to ensure stability. While this method securely fixes the casing, each screw needs to be tightened individually during assembly, which is time-consuming, labor-intensive, inefficient, and increases production costs. Clip fastening, on the other hand, is susceptible to machining and assembly errors, resulting in gaps between the outer casing parts after the clips are engaged. This can lead to relative movement and may also compromise the sealing of the internal air ducts.

[0006] Therefore, how to securely fix the outer shell of respiratory therapy equipment, reduce the difficulty of the assembly process, and improve assembly efficiency has become an urgent problem to be solved in this field. Utility Model Content

[0007] This invention provides a portable respiratory therapy device to solve the problems of complex assembly steps, low assembly efficiency, and poor assembly stability of existing respiratory therapy devices.

[0008] The technical solution adopted in this utility model is as follows:

[0009] A portable respiratory therapy device includes a housing with an airflow assembly disposed inside. The housing includes a first outer shell and a second outer shell, which are inserted and positioned along a first direction. The housing has openings at both ends along a second direction, which is perpendicular to the first direction. The respiratory therapy device also includes side covers located at both ends of the housing to close the openings. The side covers are respectively positioned and engaged with the first and second outer shells and are fixedly connected to the housing and / or the airflow assembly, so that the side covers fix the first and second outer shells; or the side covers are respectively connected to the first and second outer shells, so that the side covers fix the first and second outer shells.

[0010] The first and second outer shells have a plug-in structure at the edge of the opening, and the side cover has a mating structure. One of the plug-in structure and the mating structure is a plug-in rib, and the other is a plug-in groove that is plugged into and mated with the plug-in rib.

[0011] The side cover includes a first side cover located at one end of the housing along a second direction, and a second side cover located at the other end of the housing. The first side cover has an air inlet communicating with the air inlet of the airflow assembly.

[0012] The respiratory therapy device also includes an air intake grille, and the first side cover is provided with a mounting groove for installing the air intake grille, with the air inlet located in the mounting groove.

[0013] Both the first and second outer shells have sealing grooves along the opening edges, which together form the first insertion groove. The first side cover has a first positioning rib, which is sealed and inserted into the first insertion groove.

[0014] The first side cover is provided with a first fixing hole, the airflow assembly is provided with a first mating hole, and the respiratory therapy device also includes a first fastener, which passes through the first fixing hole and the first mating hole to fix the first side cover to the airflow assembly.

[0015] The side cover includes a first side cover located at one end of the housing along a second direction, and a second side cover located at the other end of the housing. The second side cover has an air outlet that communicates with the air outlet of the airflow assembly.

[0016] The second side cover is provided with at least two second fixing holes, and the first outer shell and the second outer shell are respectively provided with second mating holes. The respiratory therapy device also includes a second fastener, which passes through the second fixing holes and the second mating holes to fix the second side cover to the first outer shell and the second outer shell respectively.

[0017] Both the first and second outer shells have sealing grooves along the opening edges, which together form a second insertion groove. The second side cover has a second positioning rib, which is sealed and inserted into the second insertion groove.

[0018] The first outer shell has a first end face that mates with the second outer shell, and the second outer shell has a second end face that mates with the first outer shell. One of the first end face and the second end face is provided with a positioning groove, and the other end face is provided with a positioning rib that is inserted into the positioning groove.

[0019] The airflow assembly includes a fan and a mounting housing, the interior of which forms a mounting cavity for mounting the fan.

[0020] One of the inner shell and the first outer shell is provided with a fixing rib, and the other is provided with a fixing groove that engages with the fixing rib, so as to fix the inner shell and the first outer shell.

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

[0022] 1. In this utility model, the housing includes a first outer shell, a second outer shell, and side covers located at both ends of the housing. The first and second outer shells are inserted and positioned along a first direction, without any connection between them, achieving simple fixation only through insertion. The side covers are then fixed to both ends of the housing, closing the opening and simultaneously securing the first and second outer shells, thus simultaneously fixing multiple components of the housing. The side covers can be directly fixed to the first and second outer shells, or fixed to the airflow assembly inside the housing, and engage with the first and second outer shells to maintain the connection stability of the first and second outer shells. For the first and second outer shells, there is no need for fixation with multiple screws or other fasteners, saving both cost and assembly time. Furthermore, there is no need to set complex snap-fit ​​structures on the first and second outer shells, reducing processing difficulty. For the side covers, simply securing this component to the housing or the airflow assembly allows for simultaneous connection of all components of the housing, eliminating the need to connect each component individually, reducing assembly difficulty and significantly improving assembly efficiency.

[0023] 2. In a preferred embodiment of this utility model, the first and second outer shells are provided with insertion structures at the edges of their openings, and the side cover is provided with a mating structure. One of the insertion structures and the mating structure is an insertion rib, and the other is an insertion groove that engages with the insertion rib. After the side cover is installed, the insertion rib and the insertion groove engage, causing the groove wall to limit and stop the insertion rib, thus ensuring the side cover tightly clamps the first and second outer shells along a first direction, preventing them from detaching in the opposite direction. Simultaneously, the engagement of the insertion groove and the insertion rib also positions the side cover, allowing assemblers to easily install it in place and improving its positional stability. Thus, the first and second outer shells and the side cover mutually limit and position each other, improving the tightness of the fit and consequently enhancing the overall connection stability.

[0024] 3. In a preferred embodiment of this utility model, the respiratory therapy device further includes an air intake grille. The first side cover is provided with a mounting groove for installing the air intake grille, and the air inlet is located within the mounting groove. The air inlet is located on the first side cover, allowing airflow to enter the respiratory therapy device along a second direction. This not only makes the air intake path smoother and improves air intake efficiency, but also, because the respiratory therapy device is longer in the second direction, it is easier to design the air intake path, which helps to extend the air path length, reduce airflow kinetic energy, and thus achieve a noise reduction effect. The air intake grille can disperse and organize the converged airflow into multiple streams, reducing the noise generated when the airflow enters the air inlet. Simultaneously, the air intake grille can also block large particulate impurities from the outside of the air inlet, improving the cleanliness of the respiratory therapy device's interior. Furthermore, the air intake grille is installed inside the mounting groove, preventing its outer surface from excessively protruding from the first side cover, resulting in a more uniform and smooth appearance for the first side cover and the overall housing, improving structural compactness, and contributing to miniaturization and aesthetic design.

[0025] 4. In a preferred embodiment of this utility model, the first outer shell has a first end face that mates with the second outer shell, and the second outer shell has a second end face that mates with the first outer shell. One of the first and second end faces is provided with a positioning groove, and the other is provided with a positioning rib that engages with the positioning groove. After the positioning rib and positioning groove are engaged, the first and second end faces abut against each other, resulting in surface contact between the first and second outer shells. This improves the contact stability between them and reduces the possibility of relative wobbling. Furthermore, the engagement of the positioning rib and positioning groove makes the outer surfaces of the first and second outer shells essentially flush or together form an arc surface, making the outer surface of the shells smoother and improving the grip.

[0026] 5. In a preferred embodiment of this utility model, one of the inner housing and the first outer housing is provided with a fixing rib, and the other is provided with a fixing groove that engages with the fixing rib, thereby fixing the inner housing and the first outer housing. The first outer housing and the inner housing can be fixed together by the fixing rib and the fixing groove, ensuring that the first outer housing is not only limited and fixed by the side cover but also fixed to the inner housing, further improving the installation stability of the first outer housing and reducing the risk of it shaking or loosening. Simultaneously, it can further improve the assembly correlation between the various components of the respiratory therapy equipment, reduce relative shaking between components, and improve the overall assembly quality of the respiratory therapy equipment.

[0056] Many specific details are set forth in the following description in order to provide a full understanding of the present invention.

[0060] like Figures 1 to 20 As shown, a portable respiratory therapy device includes a housing 1, with an airflow assembly 5 disposed inside the housing 1. The housing 1 includes a first outer shell 11 and a second outer shell 12, which are inserted and positioned along a first direction. The housing 1 has openings at both ends along a second direction, which is perpendicular to the first direction. The respiratory therapy device also includes side covers located at both ends of the housing 1 to close the openings. The side covers are respectively limited and engaged with the first outer shell 11 and the second outer shell 12, and are fixedly connected to the housing 1 and / or the airflow assembly 5, so that the side covers fix the first outer shell 11 and the second outer shell 12; or the side covers are respectively connected to the first outer shell 11 and the second outer shell 12, so that the side covers fix the first outer shell 11 and the second outer shell 12.

[0061] Preferably, such as Figure 1 , Figure 2As shown, the second direction is the length direction of the shell 1, meaning the openings are located at both ends of the length direction of the shell 1, and the first direction is the width direction of the shell 1. Specifically, as... Figure 1 , Figure 2 As shown, with the respiratory therapy device placed on the table, the housing 1 extends horizontally, meaning the second direction is horizontal, and the side covers are located at the left and right ends of the housing 1. Figure 1 , Figure 2 As shown, the first outer shell 11 is located on top, and the second outer shell 12 is located on the bottom, with the two being inserted and connected.

[0062] In this invention, the housing 1 includes a first outer shell 11, a second outer shell 12, and side covers located at both ends of the housing 1. The first outer shell 11 and the second outer shell 12 are inserted and positioned along a first direction, without any direct connection between them, achieving simple fixation only through insertion. The side covers are then fixed to both ends of the housing 1, closing the opening and simultaneously securing the first outer shell 11 and the second outer shell 12, thus simultaneously fixing multiple components of the housing 1. The side covers can be directly fixed to the first outer shell 11 and the second outer shell 12. For example, both the first outer shell 11 and the second outer shell 12 are provided with screw holes or snap-fit ​​structures, and the side covers are directly connected to the first outer shell 11 and the second outer shell 12 by screws or snap-fits. Alternatively, the side covers can be fixedly connected to the airflow assembly 5 inside the housing 1 and engage with the first outer shell 11 and the second outer shell 12 to maintain the connection stability of the first outer shell 11 and the second outer shell 12. For the first outer shell 11 and the second outer shell 12, there is no need to use multiple screws or other fasteners for fixation, which saves both cost and assembly time. Furthermore, there is no need to set complex snap-fit ​​structures on the first and second outer shells 11 and 12 separately, reducing manufacturing difficulty. As for the side cover, simply fastening this component to the housing 1 or the airflow assembly 5 allows for the simultaneous connection of all components of the housing 1, eliminating the need to connect each component individually. This not only reduces assembly difficulty but also significantly improves assembly efficiency.

[0063] In a preferred embodiment of the present invention, the first outer shell 11 and the second outer shell 12 are provided with a plug-in structure at the edge of the opening, and the side cover is provided with a mating structure. One of the plug-in structure and the mating structure is a plug-in rib, and the other is a plug-in groove that is plugged into and mated with the plug-in rib.

[0064] After the side cover is installed, the insertion protrusion and the insertion groove engage, causing the groove wall to act as a limiting stop against the insertion protrusion. This allows the side cover to tightly clamp the first outer shell 11 and the second outer shell 12 along the first direction, preventing them from detaching in the opposite direction. Simultaneously, the engagement of the insertion groove and the insertion protrusion also positions the side cover, allowing installers to easily position it and improving its positional stability. In this way, the first outer shell 11, the second outer shell 12, and the side cover mutually limit and position each other, improving the tightness of the fit and thus enhancing the overall connection stability.

[0065] Specifically, in one embodiment, the insertion structure is an insertion groove, and the mating structure is an insertion rib; further, as... Figure 3 , Figure 4 As shown, in one example, the insertion groove is a U-shaped groove. After the insertion protrusion extends into the insertion groove, both its inner and outer sides are limited by the stop of the groove wall. In another example, the insertion groove can also be an L-shaped groove, that is, only on the inner side of the insertion protrusion (the side closer to the inside of the housing 1), so that the insertion protrusion and the stop of the groove wall on that side can restrict the movement of the first housing 11 and the second housing 12 in the opposite direction to the first direction, thereby preventing the first housing 11 and the second housing 12 from becoming loose.

[0066] Preferably, at least one side of the groove wall of the insertion slot can abut against the end face of the side cover. Specifically, when the inner side of the side cover (the side facing the interior of the housing 1) is a planar structure, the groove wall of the insertion slot abuts against the top surface structure. When the inner side of the side cover is not planar, one or more bosses can be provided on the inner side of the side cover, so that the platform of each boss forms a plane, and the groove wall of the insertion slot abuts against the plane.

[0067] Preferably, a sealing element is also provided between the insertion protrusion and the insertion groove.

[0068] Specifically, such as Figure 11 , Figure 15 As shown, both the first outer shell 11 and the second outer shell 12 are provided with arc-shaped insertion grooves. When the two are spliced ​​together, they together form an annular insertion groove. The edge of the side cover is provided with annular insertion ribs along the circumferential direction to form insertion positioning in the circumferential direction.

[0069] It should be noted that this utility model does not limit the assembly relationship of the side covers. They can be fixedly connected to the first outer shell 11 and the second outer shell 12 respectively, so as to naturally limit the first outer shell 11 and the second outer shell 12. They can also be fixedly connected to the airflow assembly 5 inside the shell 1, and fix the first outer shell 11 and the second outer shell 12 by forming a limiting fit. Of course, there are two side covers, which are located at both ends of the shell 1 respectively. The assembly relationship of the two side covers can be the same or different. For example, both side covers can be fixed to the first outer shell 11, the second outer shell 12 or the airflow assembly 5, or one side cover can be fixed to the first outer shell 11 and the second outer shell 12, and the other side cover can be fixed to the airflow assembly 5.

[0070] In a preferred embodiment, such as Figure 1 , Figure 2 , Figure 6 As shown, the side cover includes a first side cover 2 located at one end of the housing 1 along the second direction, and a second side cover 4 located at the other end of the housing 1. The first side cover 2 has an air inlet 21 that communicates with the air inlet of the airflow assembly 5.

[0071] The air inlet 21 is located on the first side cover 2, allowing airflow to enter the respiratory therapy device in the second direction. This not only makes the air intake path smoother and improves the air intake efficiency, but also makes it easier to design the air intake path in the second direction, as the length of the respiratory therapy device is relatively long. This helps to extend the air path length, reduce airflow energy, and thus achieve the effect of noise reduction.

[0072] Furthermore, such as Figure 1 , Figure 6 , Figure 7 As shown, the respiratory therapy device also includes an air intake grille 3, and the first side cover 2 is provided with an installation groove 24 for installing the air intake grille 3, with the air inlet 21 located in the installation groove 24.

[0073] The air intake grille 3 is located at the air intake 21 and can disperse and organize the converged airflow into multiple streams, reducing the noise generated when the airflow enters the air intake 21. At the same time, the air intake grille 3 can also block large particles of impurities from the outside of the air intake 21, improving the cleanliness of the inside of the respiratory therapy device. The air intake grille 3 is installed inside the mounting groove 24, so that the outer surface of the air intake grille 3 does not protrude excessively from the first side cover 2, making the overall appearance of the first side cover 2 and the housing 1 more uniform and smooth, improving structural compactness, and contributing to miniaturization and aesthetic design. Preferably, after the air intake grille 3 is installed in the mounting groove 24, its outer surface is flush with the outer surface of the first side cover 2.

[0074] Preferably, the air intake grille 3 is movable relative to the first side cover 2 to cover the air intake 21, or to avoid the air intake 21. Specifically, in one embodiment, the air intake grille 3 is detachably mounted to the first side cover 2, allowing the user to remove the air intake grille 3 from the first side cover 2 for cleaning. At this time, the air intake 21 is opened, and when the user inserts the air intake grille 3 into the mounting recess 24, it obstructs the air intake 21. The air intake grille 3 can be detachably connected to the first side cover 2 via an interference fit or snap-fit ​​connection. In another embodiment, such as... Figure 6 , Figure 8 As shown, one end of the air intake grille 3 is rotatably connected to the first side cover 2 so that the air intake grille 3 can be flipped relative to the first side cover 2 to block the air intake 21 or avoid the air intake 21.

[0075] Furthermore, such as Figure 6 , Figure 7 , Figure 8 As shown, a portion of the outer periphery of the mounting groove 24 is provided with a hand slot 25, allowing the user to insert their hand through the hand slot 25 into the mounting groove 24 to remove or open the air intake grille 3.

[0076] Preferably, such as Figure 3 , Figure 4 , Figure 11 As shown, both the first outer shell 11 and the second outer shell 12 have sealing grooves at the opening edges, and the sealing grooves together form the first insertion groove 14. The first side cover 2 is provided with a first positioning rib 22, and the first positioning rib 22 is sealed and inserted into the first insertion groove 14.

[0077] The first positioning rib 22 and the first insertion groove 14 are sealed together, which not only achieves positioning and limiting, but also seals the gap between them, thereby preventing airflow from inside the housing 1 from leaking to the outside. At the same time, when the seal is compressed, it can also increase the frictional resistance, thereby improving the insertion stability of the first positioning rib 22 and the first insertion groove 14. Specifically, in one embodiment, a first sealing ring 23 can be provided between the first positioning rib 22 and the first insertion groove 14, so that the first sealing ring 23 wraps around the outside of the first positioning rib 22, or is placed on the inner wall of the first insertion groove 14, so that after the two are inserted, the first sealing ring 23 is compressed, sealing the gap.

[0078] In another embodiment, such as Figure 4 , Figure 9 , Figure 10 As shown, the first side cover 2 is provided with an installation groove, and a first sealing ring 23 is provided in the installation groove. A portion of the first sealing ring 23 protrudes from the first side cover 2 to form a first positioning rib 22. Thus, the first sealing ring 23 is inserted into the first insertion groove 14 to achieve positioning and sealing at the same time.

[0079] like Figure 9 , Figure 10 As shown, the first sealing ring 23 is also provided with a positioning lip 231, which is used to cooperate with the groove of the first side cover 2 for positioning.

[0080] Furthermore, such as Figure 9 , Figure 11 As shown, the first side cover 2 is provided with a first fixing hole 26, the airflow assembly 5 is provided with a first mating hole 51, and the respiratory therapy device also includes a first fastener, which passes through the first fixing hole 26 and the first mating hole 51 to fix the first side cover 2 and the airflow assembly 5.

[0081] Preferably, the airflow assembly 5 can be fixed inside the first housing 11 and / or the second housing 12 by means of screw connection, snap connection or other means.

[0082] The first side cover 2 is fastened to the airflow assembly 5, which improves the assembly correlation between the first side cover 2 and the airflow assembly 5. It also plays an auxiliary role in fixing the airflow assembly 5, making the position of each component more stable. Through the fastening connection between the first side cover 2 and the airflow assembly 5, the clamping effect of the first side cover 2 on the first outer shell 11 and the second outer shell 12 is ensured, and the fastening assembly between the first outer shell 11 and the second outer shell 12 is ensured.

[0083] As a preferred embodiment, such as Figure 1 , Figure 2 , Figure 12 , Figure 13 , Figure 14 As shown, the side cover includes a first side cover 2 located at one end of the housing 1 along the second direction, and a second side cover 4 located at the other end of the housing 1. The second side cover 4 has an air outlet 41 connected to the air outlet of the airflow assembly 5.

[0084] Furthermore, the first side cover 2 is provided with an air inlet 21, so that the air inlet 21 is located at one end of the respiratory therapy device along the second direction, and the air outlet 41 is located at the other end of the respiratory therapy device. The overall airflow direction is along the second direction (i.e., the length direction of the respiratory therapy device). This can lengthen the airflow path and achieve a noise reduction effect, while also avoiding large-area overlap between multiple air paths and between the air paths and the fan 52 in the height direction. This helps to reduce the overall thickness of the respiratory therapy device and allows it to be designed into a more slender structure, making it convenient for users to hold and carry with one hand, and making it convenient for users to use.

[0085] like Figure 14 As shown, an insertion groove is provided on the outer periphery of the air outlet 41, the air outlet 41 is located in the insertion groove, the groove wall of the insertion groove is provided with a guide slope 42, and the inner periphery of the air outlet 41 is provided with a snap-fit ​​structure 421 for snap-fitting and fixing with the pipeline.

[0086] The insertion groove and guide slope 42 provide positioning for connecting external pipelines. During use, the user can connect the pipeline connected to the mask or other equipment to the air outlet 41. The guide slope 42 guides the pipeline, ensuring that even if the user does not align the pipeline with the air outlet 41, the guide slope 42 will gradually align the pipeline with the air outlet 41 during the connection process. The snap-fit ​​structure 421 on the inner circumference of the air outlet 41 can snap-fit ​​the pipeline. Compared to a simple insertion method, the snap-fit ​​fixation improves the stability of the connection and reduces the possibility of pipeline loosening and leakage.

[0087] Furthermore, such as Figure 12 , Figure 15 As shown, the second side cover 4 is provided with at least two second fixing holes 46, the first outer shell 11 and the second outer shell 12 are respectively provided with second mating holes 18, and the respiratory therapy device also includes a second fastener, which passes through the second fixing holes 46 and the second mating holes 18 to fix the second side cover 4 to the first outer shell 11 and the second outer shell 12 respectively.

[0088] Specifically, there are two second fasteners. One fastener secures the second side cover 4 to the first housing 11 through a second fixing hole 46 and a second mating hole 18 of the first housing 11. The other fastener secures the second side cover 4 to the second housing 12 through a second fixing hole 46 and a second mating hole 18 of the second housing 12. This ensures that the second side cover 4 is simultaneously secured to both the first housing 11 and the second housing 12, making the assembly of the first housing 11 and the second housing 12 more stable.

[0089] like Figure 14 As shown, a shielding cover 47 is also provided on the outer side of the second side cover 4 (the side facing away from the inside of the housing 1). The shielding cover 47 can shield the second fixing hole 46 to improve the overall appearance quality of the respiratory therapy device.

[0090] Preferably, such as Figure 5 , Figure 12 , Figure 13 , Figure 15 As shown, both the first outer shell 11 and the second outer shell 12 have sealing grooves at the opening edges, and the sealing grooves together form the second insertion groove 15. The second side cover 4 is provided with a second positioning rib 43, and the second positioning rib 43 is sealed and inserted into the second insertion groove 15.

[0091] Specifically, a second sealing ring 44 is provided between the second side cover 4 and the housing 1. The second sealing ring 44 has a first sealing part 441 located between the two to seal the gap between the second side cover 4 and the housing 1.

[0092] Preferably, such as Figure 3 , Figure 5 , Figure 12 , Figure 13 , Figure 15 , Figure 16 As shown, an air outlet pipe 16 is provided inside the housing 1. One end of the air outlet pipe 16 is connected to the air outlet of the airflow assembly 5, and the other end is connected to the air outlet 41. A bracket 17 is also provided on the outer periphery of the air outlet pipe 16 to improve the stability of the air outlet pipe 16. The second side cover 4 is also provided with a limiting part 45 for cooperating with the bracket 17 for limiting. The second sealing ring 44 also has a second sealing part 442 located between the limiting part 45 and the bracket 17, so that the second sealing ring 44 can simultaneously perform the sealing function between the second side cover 4 and the housing 1, and between the second side cover 4 and the bracket 17. This multi-functional design simplifies the structure of the respiratory therapy device and saves costs.

[0093] Specifically, such as Figure 13 As shown, the first sealing part 441 and the second sealing part 442 are connected as one unit by a connecting rib.

[0094] Preferably, such as Figure 18 , Figure 19 As shown, the first outer shell 11 has a first end face 113 that mates with the second outer shell 12, and the second outer shell 12 has a second end face 122 that mates with the first outer shell 11. One of the first end face 113 and the second end face 122 is provided with a positioning groove 112, and the other of the two is provided with a positioning rib 121 that is inserted into the positioning groove 112.

[0095] After the positioning rib 121 and the positioning groove 112 are inserted, the first end face 113 and the second end face 122 abut against each other, making the first outer shell 11 and the second outer shell 12 in surface contact, thereby improving the contact stability between the two and reducing the possibility of relative shaking. In addition, after the positioning rib 121 and the positioning groove 112 are inserted, the outer surfaces of the first outer shell 11 and the second outer shell 12 are basically flush or together form an arc surface, making the outer surface of the shell 1 smoother and improving the grip.

[0096] Specifically, a sealing strip 63 is provided between the positioning rib 121 and the positioning groove 112. The sealing strip 63 can protrude from the first end face 113 or the second end face 122 to form the positioning rib 121 for insertion into the positioning groove 112.

[0097] As a preferred embodiment, such as Figures 16 to 18 As shown, the airflow assembly 5 includes a fan 52 and a mounting inner shell 6, with a mounting cavity 62 formed inside the mounting inner shell 6 for mounting the fan 52.

[0098] By installing the fan 52 inside the mounting housing 6, the heat and vibration generated by the fan 52 during operation are less likely to escape to the housing 1, thereby improving the user's handling and grip experience. Simultaneously, the air passages connecting the fan 52's inlet and outlet are also located inside the mounting housing 6, allowing airflow to converge and more effectively enter and exit the fan 52, improving airflow efficiency and thus enhancing the fan 52's intake and exhaust efficiency.

[0099] like Figure 16 , Figure 17 As shown, the airflow assembly 5 also includes an air inlet housing 53 located outside the mounting inner housing 6 and along the second direction on one side of the mounting inner housing 6 (near the first side cover 2). The air inlet housing 53 has a curved air inlet passage inside, so that the air inlet 21 is connected to the air inlet of the fan 52 through the air inlet passage. The first side cover 2 is fixedly connected to the air inlet housing 53.

[0100] Preferably, such as Figure 17 , Figure 19 , Figure 20 As shown, one of the inner shell 6 and the first outer shell 11 is provided with a fixing rib 111, and the other is provided with a fixing groove 61 that engages with the fixing rib 111, so as to fix the inner shell 6 and the first outer shell 11.

[0101] The first outer shell 11 and the mounting inner shell 6 can be fixed together by the fixing ribs 111 and the fixing grooves 61. This ensures that the first outer shell 11 is not only fixed by the side covers but also fixed to the mounting inner shell 6, further improving the installation stability of the first outer shell 11 and reducing the risk of it shaking or loosening. It also further improves the assembly correlation between the various components of the respiratory therapy device, reduces relative shaking between components, and improves the overall assembly quality of the respiratory therapy device. Furthermore, since the first side covers 2 and the second side covers 4 clamp and limit the ends of the first outer shell 11 and the second outer shell 12, the middle part of the first outer shell 11 and the second outer shell 12 may deform or even develop gaps due to stress. Therefore, the fixing ribs 111 and the fixing grooves 61 limit the middle part of the first outer shell 11 to prevent gaps from appearing.

[0102] Specifically, such as Figure 1 , Figure 17 , Figure 18 , Figure 20As shown, the second outer shell 12 is located below the first outer shell 11. After the airflow assembly 5 is installed on the second outer shell 12, it covers the second outer shell 11 to seal the mounting cavity 62. The mounting inner shell 6 is provided with multiple fixing grooves 61, and each fixing groove 61 is spaced apart along the second direction. The first outer shell 11 is correspondingly provided with multiple fixing ribs 111 so that the fixing ribs 111 are engaged with the fixing grooves 61 one by one. Preferably, fixing grooves 61 are provided on both sides of the mounting inner shell 6, and the cross-section of the first outer shell 11 is an arc-shaped structure. Fixing ribs 111 are correspondingly provided at both ends of the arc to form a uniform engagement force at both ends of the first outer shell 11, preventing the first outer shell 11 from warping locally.

[0103] Preferably, such as Figure 1 , Figure 2 As shown, a decorative shell 13 is also provided on the outer side of the housing 1. The decorative shell 13 covers a part of the housing 1 to form a step between the decorative shell 13 and the housing 1, and the step forms a gripping area. The presence of the decorative shell 13 makes the outer surface of the housing 1 uneven, thereby increasing the friction when the user grips it, making the user hold it more firmly.
