Description

Technical Field

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

[0002] With the development of medical technology, ventilators have been widely used in clinical treatment and home care. Current ventilators typically include a gas delivery system and a humidification structure. During delivery, the gas passes through the humidification structure, carrying a certain amount of moisture before being delivered to the patient, reducing discomfort caused by inhaling overly dry gas. Simultaneously, ventilators are also equipped with a heating structure to heat the gas during delivery, improving patient comfort.

[0003] During long-term use of ventilators, the humidification structure needs to come into contact with the humidification liquid, which can easily lead to the formation of deposits or other substances. Therefore, regular cleaning is necessary to ensure humidification effectiveness and hygiene. However, some existing ventilators integrate the humidification structure with heating components, electrical connection components, etc., forming a single unit. The humidification structure usually requires rinsing or soaking during cleaning, while the electrical components should not come into contact with water, requiring additional protection for the electrical components during cleaning. At the same time, the integrated structure also causes some areas of the humidification structure to be interfered with by other components, restricting cleaning operations and making it difficult to thoroughly clean the humidification structure, thus increasing the difficulty of cleaning the humidification structure. Summary of the Invention

[0019] In one alternative embodiment, one end of the base is mounted on the lower surface of the upper housing, and the other end passes through the mounting hole and protrudes from the upper surface of the upper housing.

[0020] In one optional embodiment, the stop member includes two abutments disposed on the lower surface of the upper housing, the two abutments being spaced apart along the rotation direction of the base, and the abutments being used to engage with the base.

[0021] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows: This application allows the humidifier to be detachably housed within the main unit's housing, enabling independent assembly and disassembly relative to the main unit. Therefore, when cleaning the humidifier is required, it can be removed from the housing, separating it from the electrical components on the main unit. This avoids interference from the electrical components during cleaning, facilitating rinsing, soaking, and other cleaning operations, thus improving the ease of cleaning. Simultaneously, by housing the electrical components within the main unit, the humidifier and electrical components are structurally separated. When the humidifier is removed for cleaning, there is no need to clean the electrical components along with the humidifier or take additional waterproofing measures, further reducing the difficulty of cleaning the humidifier. Furthermore, by detachably installing the heating pipe within the humidifier's outlet pipe, the heating pipe can be easily detached from the humidifier as needed. When the humidifier is installed into the receiving cavity and the heating pipeline is installed into the outlet pipe, the electrical connection terminal can correspond with the electrical components in the main unit and establish an electrical connection. This allows the electrical connection of the heating pipeline to be realized at the same time as the installation of the humidifier and the heating pipeline, thus eliminating the need for additional electrical connection operations, ensuring that the heating pipeline can work normally, and improving the ease of assembly and use of the heated ventilator.

[0024] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below. It should be noted that, unless otherwise specified, the embodiments of this application and the features thereof can be combined with each other.

[0026] Furthermore, it should be understood in the description of this application that the terms "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0027] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0029] like Figure 1 , Figure 2 , Figure 3As shown, this application discloses a heated ventilator, including: a main unit 1, the main unit 1 having a receiving cavity 11, the main unit 1 having an electrical component 12; a humidifier 2, the humidifier 2 having an air outlet tube 21, the humidifier 2 being detachably installed in the receiving cavity 11; and a heated pipeline 3, the heated pipeline 3 including an electrical connection terminal 31, the heated pipeline 3 being detachably installed in the air outlet tube 21; wherein, when the humidifier 2 is installed in the receiving cavity 11 and the heated pipeline 3 is installed in the air outlet tube 21, the electrical connection terminal 31 is electrically connected to the electrical component 12.

[0030] This application allows the humidifier 2 to be detachably installed in the receiving cavity 11 of the main unit 1, enabling the humidifier 2 to be independently installed and removed relative to the main unit 1. Therefore, when cleaning the humidifier 2 is required, it can be removed from the receiving cavity 11, separating the humidifier 2 from the electrical components 12 on the main unit 1. This avoids interference from the electrical components 12 during the cleaning operation of the humidifier 2, facilitating cleaning operations such as rinsing and soaking, and improving the convenience of cleaning the humidifier 2. Simultaneously, by installing the electrical components 12 on the main unit 1, the humidifier 2 and the electrical components 12 are structurally separated. When the humidifier 2 is removed for cleaning, there is no need to clean the electrical components 12 along with the humidifier 2 or take additional waterproof protection measures, further reducing the difficulty of cleaning the humidifier 2. Furthermore, by detachably installing the heating pipe 3 to the air outlet pipe 21 of the humidifier 2, the heating pipe 3 can be disassembled and installed from the humidifier 2 as needed. When the humidifier 2 is installed into the receiving cavity 11 and the heating pipe 3 is installed into the air outlet pipe 21, the electrical connection terminal 31 can correspond to and establish an electrical connection with the electrical components 12 in the main unit 1. This allows the electrical connection of the heating pipe 3 to be achieved simultaneously with the installation of the humidifier 2 and the heating pipe 3, thus eliminating the need for additional electrical connection operations. This ensures that the heating pipe 3 can work normally and improves the ease of assembly and use of the heated ventilator.

[0031] In this application, the electrical component 12 can be arranged in any of the following embodiments: Implementation method one: such as Figure 1 , Figure 2 , Figure 3 As shown, the electrical component 12 includes a positioning seat 121 adapted to the air outlet pipe 21. When the humidifier 2 is installed into the receiving cavity 11, the air outlet pipe 21 cooperates with the positioning seat 121.

[0032] By setting a positioning seat 121 that is compatible with the air outlet pipe 21, when the humidifier 2 is installed into the receiving cavity 11, the air outlet pipe 21 can cooperate with the positioning seat 121 to position the air outlet pipe 21, so that the air outlet pipe 21 can be kept in the predetermined position, thereby improving the accuracy of the fit and the stability of the connection when the air outlet pipe 21 is connected to the heating pipe 3.

[0033] Implementation Method 2: This implementation method is not illustrated. The main unit is provided with a positioning groove that matches the air outlet pipe. When the humidifier is installed into the receiving cavity, the air outlet pipe is at least partially embedded in the positioning groove.

[0034] Furthermore, the electrical components are located on one side of the positioning groove.

[0035] In embodiment one, the arrangement of the air outlet pipe 21 and the positioning seat 121 can be any of the following embodiments: Example 1: As Figure 1 , Figure 2 , Figure 3 As shown, the positioning seat 121 is provided with a snap-fit ​​groove 1211 that cooperates with the air outlet pipe 21, and the air outlet pipe 21 is snapped into the snap-fit ​​groove 1211.

[0036] By setting a snap-fit ​​groove 1211 in the positioning seat 121 to cooperate with the air outlet pipe 21, the air outlet pipe 21 is snapped into the snap-fit ​​groove 1211, thereby forming a stable snap-fit ​​limit on the air outlet pipe 21, restricting the movement of the air outlet pipe 21 relative to the positioning seat 121, so that the air outlet pipe 21 can be kept in a predetermined position, improving the positioning stability of the air outlet pipe 21 and the reliability of the connection with the heating pipeline 3.

[0037] Example 2: This example 2 is not shown in the figure. The positioning seat is provided with a positioning groove that cooperates with the air outlet pipe. The air outlet pipe abuts against the positioning groove.

[0038] By setting a positioning groove in the positioning seat to match the air outlet pipe, the air outlet pipe abuts against the positioning groove, thereby using the groove wall to limit the air outlet pipe. This not only positions the air outlet pipe but also facilitates the assembly and disassembly of the air outlet pipe and the positioning seat, improving the ease of operation during the installation and disassembly of the humidifier.

[0039] In the first embodiment, the positioning base 121 can be configured in any of the following embodiments: Example 3: As Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the positioning seat 121 is rotatably mounted on the main unit 1, and the air outlet pipe 21 is rotatably mounted on the humidifier 2. When the humidifier 2 is installed into the receiving cavity 11, the air outlet pipe 21 and the positioning seat 121 can rotate synchronously.

[0040] By rotatably mounting the positioning seat 121 on the main unit 1 and rotatably mounting the air outlet pipe 21 on the humidifier 2, the air outlet pipe 21 and the positioning seat 121 can rotate synchronously after the humidifier 2 is installed in the receiving cavity 11. This allows the air outlet pipe 21 to rotate relative to the main unit 1 while maintaining cooperation with the positioning seat 121. The operator can adjust the orientation of the air outlet pipe 21 according to actual usage needs to facilitate the connection and use of the heating pipeline 3, thereby improving the ease of operation during the use of the heated ventilator.

[0041] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 6 As shown, the positioning seat 121 has a rotating state and a locked state. When the humidifier 2 is separated from the receiving cavity 11, the positioning seat 121 switches to the locked state; when the humidifier 2 is installed into the receiving cavity 11, the positioning seat 121 switches to the rotating state.

[0042] By enabling the positioning seat 121 to have a rotating state and a locked state, and switching the state of the positioning seat 121 according to the assembly state of the humidifier 2 and the receiving cavity 11, when the humidifier 2 is separated from the receiving cavity 11, the positioning seat 121 is in the locked state, thereby restricting the rotation of the positioning seat 121 and keeping the positioning seat 121 in a predetermined position, so that the humidifier 2 can be accurately matched with the air outlet pipe 21 when it is installed into the receiving cavity 11; after the humidifier 2 is installed into the receiving cavity 11, the positioning seat 121 is switched to the rotating state, so that the positioning seat 121 can rotate with the air outlet pipe 21, thereby making it easier for the operator to adjust the orientation of the air outlet pipe 21 during use, improving the flexibility and ease of operation of the air outlet pipe 21.

[0043] Example 4: This example 4 is not shown in the figure. The positioning seat is fixedly installed on the main unit, and the air outlet pipe is rotatably installed on the humidifier. When the humidifier is installed into the receiving cavity, the air outlet pipe is rotatably installed on the positioning seat. The electrical components include a conductive element rotatably installed on the positioning seat. The conductive element is used for electrical connection with the electrical connection terminal. When the humidifier is installed into the receiving cavity and the heating pipe is installed into the air outlet pipe, the heating pipe, the air outlet pipe, and the conductive element rotate synchronously.

[0044] Furthermore, the positioning seat is provided with an assembly groove that fits the contour of the air outlet pipe. The positioning seat is provided with a rotating component, and a conductive component is installed on the rotating component. The rotating component is rotatably positioned on the positioning seat, and the rotation direction of the rotating component is coaxial with the rotation direction of the air outlet pipe.

[0045] In embodiment 3, the installation configuration of the positioning base 121 can be any of the following specific examples: Specific example 1: if Figure 1 , Figure 3 , Figure 5 As shown, the main unit 1 is provided with a mounting hole 13 for accommodating the positioning seat 121, and the accommodating cavity 11 is provided with an inlet and outlet 111 for the humidifier 2 to enter and exit. The mounting hole 13 is connected to the accommodating cavity 11.

[0046] By providing a mounting hole 13 for accommodating the positioning seat 121 in the main unit 1, the positioning seat 121 can be stably assembled on the main unit 1. By communicating the mounting hole 13 with the receiving cavity 11, the positioning seat 121 can directly cooperate with the air outlet pipe 21 of the humidifier 2 in the receiving cavity 11. Thus, the mounting hole 13 is used to install the positioning seat 121, so that a direct cooperation relationship is formed between the positioning seat 121 and the air outlet pipe 21, which facilitates the positioning of the air outlet pipe 21.

[0047] Furthermore, such as Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, the inlet and outlet 111 are provided with a notch 112, the mounting hole 13 communicates with the notch 112, and the humidifier 2 is provided with a fitting 22 that mates with the notch 112. The air outlet pipe 21 is provided on the fitting 22, and the outer contour of the fitting 22 is adapted to the notch 112.

[0048] By providing a notch 112 at the inlet / outlet 111, and connecting the mounting hole 13 to the notch 112, the mounting hole 13 can be connected to the inlet / outlet 111, thus aligning the mounting position of the positioning seat 121 with the assembly position of the humidifier 2. This facilitates the fitting of the positioning seat 121 with the humidifier 2 when it is installed into the receiving cavity 11. Furthermore, by placing the air outlet pipe 21 on the fitting 22 and adapting the outer contour of the fitting 22 to the notch 112, the fitting 22 can be inserted into the notch 112 when the humidifier 2 is installed into the receiving cavity 11. This allows the humidifier 2 to be positioned using the fit between the notch 112 and the fitting 22, and the air outlet pipe 21 moves with the fitting 22 to the position corresponding to the mounting hole 13. This ensures that the air outlet pipe 21 can accurately enter the mounting hole 13 and fit with the positioning seat 121, improving the installation accuracy of the humidifier 2.

[0049] Specific Example 2: This specific example 2 is not illustrated. The main unit has a mounting slot, and the positioning seat is rotatably mounted in the mounting slot via a rotating component. Further, the rotating component can be a shaft or bearing, etc.

[0050] In embodiment 3, the switching setting between the rotation state and the locked state can be any of the following examples: Example 1: such as Figure 1 , Figure 3 , Figure 6 As shown, the main unit 1 is provided with a locking member 14. When the locking member 14 is in a position close to the positioning seat 121, the positioning seat 121 is in a locked state; when the locking member 14 is in a position far away from the positioning seat 121, the positioning seat 121 is in a rotating state.

[0051] By setting a locking member 14 on the main unit 1, and having the locking member 14 in a position close to the positioning seat 121 and a position far away from the positioning seat 121, the humidifier 2 can be disassembled and assembled. When the locking member 14 is in the position close to the positioning seat 121, the positioning seat 121 is in a locked state. When the locking member 14 is in the position far away from the positioning seat 121, the positioning seat 121 is in a rotating state. This allows the disassembly and assembly of the humidifier 2 to cooperate with the locking member 14. When the humidifier 2 is disassembled, the rotation of the positioning seat 121 is restricted, keeping the positioning seat 121 stable. After the humidifier 2 is installed, the restriction on the positioning seat 121 is released, allowing the positioning seat 121 to rotate with the air outlet pipe 21. This takes into account both the positioning requirements during the disassembly and assembly of the humidifier 2 and the rotation requirements of the air outlet pipe 21 during use.

[0052] Furthermore, such as Figure 3 , Figure 6 As shown, the locking member 14 is disposed near the positioning seat 121, and the positioning seat 121 is provided with a locking groove 1212 that cooperates with the locking member 14.

[0053] By placing the locking member 14 close to the positioning seat 121, the mating distance between the locking member 14 and the positioning seat 121 is shortened, thereby reducing the arrangement space required for the locking member 14 to mate with the positioning seat 121 and improving the utilization rate of the internal space of the host 1. At the same time, the locking member 14 can mate with the locking groove 1212, thereby circumferentially limiting the positioning seat 121, restricting the rotation of the positioning seat 121, and keeping the positioning seat 121 in a predetermined position, thus improving the stability of the positioning seat 121.

[0054] In this application, the locking member 14 can be configured in the following ways: the locking member is elastically set, and when the humidifier is separated from the receiving cavity, the locking member enters the locking groove; when the humidifier is installed into the receiving cavity, the humidifier pushes the locking member out of the locking groove. Or, such as Figure 1 , Figure 6 As shown, the main unit 1 has a guide cavity 151 near the locking member 14, and an elastic member 152 is provided in the guide cavity 151. The locking member 14 is movably disposed in the guide cavity 151. The humidifier 2 is separated from the receiving cavity 11. The elastic member 152 pushes the locking member 14 to cooperate with the locking groove 1212. The humidifier 2 is installed into the receiving cavity 11. The humidifier 2 drives the locking member 14 to compress the elastic member 152, so that the locking member 14 is disengaged from the locking groove 1212.

[0055] When the locking element is elastically set, it can undergo elastic deformation under external force. This allows the locking element to enter and maintain its engagement with the locking groove when the humidifier separates from the receiving cavity. Conversely, when the humidifier is installed into the receiving cavity, it can directly push the locking element out of the locking groove. This utilizes the locking element's inherent elasticity to achieve both engagement and disengagement, enabling the humidifier's installation and removal to directly switch the locking state of the positioning seat, reducing the need for additional locking drive structures.

[0056] When the locking member 14 is disposed in the guide cavity 151 and the elastic member 152 is disposed in the guide cavity 151, the guide cavity 151 can guide the movement of the locking member 14, and the elastic member 152 can provide an elastic force to the locking member 14. Therefore, when the humidifier 2 is separated from the receiving cavity 11, the elastic member 152 can push the locking member 14 to engage with the locking groove 1212 to lock the positioning seat 121; when the humidifier 2 is installed into the receiving cavity 11, the humidifier 2 can drive the locking member 14 to move along the guide cavity 151 and compress the elastic member 152, causing the locking member 14 to disengage from the locking groove 1212, so that the locking member 14 can stably switch the engagement state with the locking groove 1212 under the guidance of the guide cavity 151, and the elastic member 152 can be used to reset the locking member 14, improving the reliability of locking and unlocking the positioning seat 121.

[0057] Furthermore, such as Figure 1 , Figure 3 , Figure 6 As shown, the main unit 1 has a guide seat 15 near the locking member 14, and a guide cavity 151 is disposed in the guide seat 15. One end of the elastic member 152 is connected to the cavity wall of the guide cavity 151, and the other end is connected to the locking member 14. The locking member 14 has an abutment member 141, which is disposed at the end of the locking member 14 facing near the receiving cavity 11, and is used to abut against the humidifier 2. During the process of installing the humidifier 2 into the receiving cavity 11, the humidifier 2 abuts against the abutment member 141, and the abutment member 141 drives the locking member 14 to compress the elastic member 152, so that the locking member 14 is disengaged from the locking groove 1212.

[0058] As a preferred option, such as Figure 4 , Figure 6 As shown, the humidifier 2 is provided with a relief groove 23 corresponding to the guide seat 15, and a pusher 24 for abutting against the abutting member 141 is provided in the relief groove 23.

[0059] By providing a guide seat 15 near the locking member 14 on the main unit 1 and placing a guide cavity 151 within the guide seat 15, the locking member 14 can move within the guide cavity 151. Simultaneously, one end of an elastic member 152 is connected to the cavity wall of the guide cavity 151, and the other end is connected to the locking member 14, allowing the elastic member 152 to provide an elastic force to the locking member 14. This enables the locking member 14 to stably engage with the locking groove 1212 under the guidance of the guide cavity 151, and to return to its engaged position with the locking groove 1212 after being subjected to external force. Furthermore, by providing an abutment member 141 at the end of the locking member 14 facing away from the positioning seat 121, the abutment member 141 can abut against the humidifier 2. During the installation of the humidifier 2 into the receiving cavity 11, the humidifier 2 abuts against the abutting member 141, and the abutting member 141 drives the locking member 14 to compress the elastic member 152, thereby disengaging the locking member 14 from the locking groove 1212. Thus, the humidifier 2's own installation action drives the locking member 14, making the installation process of the humidifier 2 linked with the unlocking process of the positioning seat 121, without requiring additional operation on the locking member 14. The elastic member 152 is compressed after the locking member 14 disengages from the locking groove 1212, providing elasticity for the locking member 14 to subsequently re-engage with the locking groove 1212.

[0060] Example 2: This example 2 is not illustrated. The main unit is equipped with a mating part, and the positioning seat is equipped with a locking part. The locking part can engage or disengage with the mating part. When the locking part engages with the mating part, it restricts the rotation of the positioning seat relative to the main unit, so that the positioning seat is in a locked state. When the locking part disengages from the mating part, it releases the rotation restriction on the positioning seat, so that the positioning seat is in a rotating state.

[0061] Furthermore, the locking component includes an electromagnetic component, and the mating component includes a magnetic attraction part capable of magnetically engaging with the electromagnetic component; when the electromagnetic component is energized, it engages with the magnetic attraction part to restrict the rotation of the positioning seat; when the electromagnetic component is de-energized, it disengages from the magnetic attraction part, allowing the positioning seat to rotate. The positioning seat is equipped with a trigger key to control the energization or de-energization of the electromagnetic component. The magnetic attraction part is arranged in a ring, and the electromagnetic component moves along the magnetic attraction part while remaining in contact with it.

[0062] Those skilled in the art will understand that the locking method of the locking member 14 is not limited to the above-described settings. A drive mechanism can also be provided on the host 1 to connect with the locking member 14, so as to drive the locking member 14 to extend and retract, so that the locking member 14 can engage or disengage with the positioning seat 121, thereby realizing the locking or unlocking of the positioning seat 121.

[0063] In embodiment 3, the structural configuration of the positioning seat 121 can be any of the following specific examples: Specific example 3: if Figure 3 , Figure 7 , Figure 8As shown, the positioning seat 121 includes a base 1213 and a housing 1214. The electrical component 12 also includes a conductive connector 122. The base 1213 and the housing 1214 form an accommodating space. The conductive connector 122 is fixedly placed in the accommodating space. The electrical connection end 31 is electrically connected to the conductive connector 122.

[0064] By forming an accommodating space with the base 1213 and the outer shell 1214, and fixing the conductive connector 122 in the accommodating space, the accommodating space provides installation, support and positioning for the conductive connector 122, keeping the conductive connector 122 in a predetermined position. At the same time, the base 1213 and the outer shell 1214 form a shield and protection for the conductive connector 122, reducing the conductive connector 122 from external collisions or other interference. When the heating pipe 3 is installed to the air outlet pipe 21, the electrical connection end 31 can accurately mate with the conductive connector 122, thereby improving the reliability of the electrical connection.

[0065] Furthermore, the base 1213 and the outer shell 1214 are detachably connected, facilitating their assembly and disassembly as needed. Specifically, the base 1213 and the outer shell 1214 can be detachably connected via snap-fit, fastener connection, magnetic connection, or other methods. This detachable connection allows the base 1213 and the outer shell 1214 to be separated, facilitating the opening of the accommodating space formed by them. This, in turn, facilitates the inspection, maintenance, or replacement of the conductive connector 122 located within the accommodating space. Simultaneously, maintenance of the conductive connector 122 does not require the complete disassembly of the positioning seat 121, improving the convenience of maintaining the electrical components 12.

[0066] Furthermore, such as Figure 1 , Figure 6 , Figure 7 As shown, the base 1213 is provided with a wire passage hole 1215, through which the power supply line 16 of the main unit 1 passes and connects to the conductive connector 122. By providing a wire passage hole 1215 in the base 1213, the power supply line 16 of the main unit 1 can pass through the wire passage hole 1215 and connect to the conductive connector 122, thereby providing a predetermined wire path for the power supply line 16, enabling the power supply line 16 to be accurately connected to the conductive connector 122 within the accommodating space, facilitating a stable connection between the power supply line 16 and the conductive connector 122.

[0067] Furthermore, such as Figure 6 , Figure 8As shown, the power supply line 16 is disposed on the top wall of the receiving cavity 11. The top wall of the receiving cavity 11 is provided with a fixing component, which has a guide cavity 17. The power supply line 16 is disposed in the guide cavity 17. The fixing component also includes a guide seat 15, which has a guide cavity 151 that cooperates with the locking member 14. The locking member 14 is used to lock the positioning seat 121. The guide seat 15 and the guide cavity 17 are arranged side by side.

[0068] By providing a fixing component on the top wall of the receiving cavity 11, and having the fixing component simultaneously provide a guide cavity 17 for accommodating the power supply line 16 and a guide cavity 151 for guiding the locking member 14, the power supply line 16 and the locking member 14 can be centrally arranged in the top wall area of ​​the receiving cavity 11. This reduces the dispersed arrangement of related structures within the host 1, facilitates the unified arrangement of structures within the receiving cavity 11, and improves the utilization rate of the internal space of the host 1. At the same time, the guide cavity 17 can guide and position the power supply line 16, and the guide cavity 151 can guide the movement of the locking member 14, thereby facilitating the connection between the power supply line 16 and the conductive connector 122, as well as the cooperation between the locking member 14 and the positioning seat 121.

[0069] Specific Example 4: This specific example 4 is not illustrated. The positioning seat is provided with a fastening hole, and the electrical component also includes a conductive connector, which is snapped into the fastening hole.

[0070] In specific example 3, the conductive connector 122 can be fixed in any of the following ways: Example 3: Not illustrated in Example 3, the base or housing has a mounting cavity adapted to the shape of the conductive connector, and the conductive connector is fixedly placed in the mounting cavity. The mounting cavity serves as an accommodating space.

[0071] By setting a mounting cavity in the base or housing that matches the shape of the conductive connector, and using the mounting cavity as a receiving space, the conductive connector can be fixedly placed in the mounting cavity. The mounting cavity is used to house the conductive connector, and the matching relationship between the mounting cavity and the shape of the conductive connector is used to position and limit the conductive connector, reduce the offset of the conductive connector in the mounting cavity, and keep the conductive connector in a position corresponding to the electrical connection end, so as to facilitate accurate docking between the electrical connection end and the conductive connector.

[0072] Example 4: Figure 8 As shown, the base 1213 has a first mounting cavity 1216, and the outer shell 1214 has a second mounting cavity 1216. The first mounting cavity 1216 and the second mounting cavity 1216 surround each other to form a mounting cavity 1216 that is adapted to the shape of the conductive connector 122. The conductive connector 122 is fixedly placed in the mounting cavity 1216. The mounting cavity 1216 serves as an accommodating space.

[0073] By providing a first mounting cavity 1216 in the base 1213 and a second mounting cavity 1216 in the outer shell 1214, the first mounting cavity 1216 and the second mounting cavity 1216 surround and form a mounting cavity 1216 that is adapted to the shape of the conductive connector 122. The conductive connector 122 is then fixedly placed in the mounting cavity 1216. Thus, the mounting cavity 1216 formed by the base 1213 and the outer shell 1214 accommodates and covers the conductive connector 122, and the fitting relationship between the mounting cavity 1216 and the shape of the conductive connector 122 ensures the proper placement of the conductive connector 122. 22 provides positioning and support, ensuring that the conductive connector 122 can be stably positioned in the predetermined location; simultaneously, the base 1213 and the outer shell 1214 can shield the conductive connector 122 from different directions, thereby protecting the conductive connector 122 and facilitating accurate docking between the electrical connection end 31 and the conductive connector 122; when it is necessary to inspect and maintain the conductive connector 122, the mounting cavity 1216 can be opened by disassembling the base 1213 and the outer shell 1214, so as to facilitate the inspection, maintenance or replacement of the conductive connector 122, thereby improving the convenience of maintenance of the electrical component 12.

[0074] Example 5: such as Figure 7 , Figure 8 As shown, the base 1213 and / or the housing 1214 are provided with a plurality of positioning members 12131 along the circumference of the conductive connector 122, and the plurality of positioning members 12131 cooperate to fix the conductive connector 122. The positioning members 12131 are disposed within the accommodating space. The base 1213 is also provided with a plurality of auxiliary support members 12136, the auxiliary support members 12136 being located at the end of the conductive connector 122 facing the positioning base 121. The auxiliary support members 12136 are used to adjust the placement angle of the conductive connector 122.

[0075] By providing multiple positioning elements 12131 along the circumference of the conductive connector 122 on the base 1213 and / or the housing 1214, and by having the multiple positioning elements 12131 cooperate to fix the conductive connector 122, the multiple positioning elements 12131 can position and limit the conductive connector 122 from different circumferential positions, thereby improving the stability of the conductive connector 122 after installation, reducing the displacement or shaking of the conductive connector 122, and ensuring accurate matching between the conductive connector 122 and the electrical connection terminal 31; at the same time, by setting the positioning elements 12131 in the accommodating space, the positioning elements 12131 and the conductive connector 122 can be concentrated in the accommodating space, reducing the additional installation space occupied, and the base 1213 and / or the housing 1214 form a shielding protection for the positioning elements 12131 and the conductive connector 122.

[0076] Furthermore, such as Figure 8As shown, the housing 1214 is provided with a limiting member 12141, which is used to abut against the conductive connector 122 to cooperate with multiple positioning members 12131 to fix the conductive connector 122. By setting the limiting member 12141, the limiting member 12141 can apply abutting action to the conductive connector 122 from a direction different from that of the positioning members 12131, thereby forming a multi-directional limiting of the conductive connector 122 together with the multiple positioning members 12131, reducing the displacement or shaking of the conductive connector 122 in the accommodating space, improving the installation stability of the conductive connector 122, and thus ensuring a stable fit between the conductive connector 122 and the electrical connection terminal 31.

[0077] In this application, the connection between the heating pipe 3 and the exhaust pipe 21 is configured as follows: Figure 1 , Figure 2 , Figure 7 , Figure 8 As shown, the heating pipe 3 has a connection hole that mates with the exhaust pipe 21. An electrical connection end 31 is provided on one side of the connection hole. The positioning seat 121 has an opening that connects to the accommodating space. The electrical connection end 31 can extend into the opening and be inserted into the conductive connector 122. The heating pipe 3 also includes a snap-fit ​​component 32. The positioning seat 121 has a snap-fit ​​groove 12132. The snap-fit ​​component 32 has a snap-fit ​​protrusion that mates with the snap-fit ​​groove 12132. The heating pipe 3 also includes an operating component 33. The operating component 33 is connected to the end of the snap-fit ​​component 32 that is away from the snap-fit ​​protrusion. By pressing the operating component 33, the snap-fit ​​protrusion is disengaged from the snap-fit ​​groove 12132, thereby realizing a detachable connection between the heating pipe 3 and the exhaust pipe 21.

[0078] The heating pipe 3 connects to the exhaust pipe 21 via a connecting hole, allowing the heating pipe 3 to be fitted onto the exhaust pipe 21 and establishing a connection between them. Simultaneously, the snap-fit ​​protrusion engages with the slot 12132, limiting the assembly position of the heating pipe 3 relative to the positioning seat 121. This ensures the heating pipe 3 remains in the predetermined connection position after installation, facilitating a stable insertion between the electrical connection end 31 and the conductive connector 122. During disassembly, pressing the operating component 33 disengages the snap-fit ​​protrusion from the slot 12132, releasing the restriction on the heating pipe 3 and allowing it to separate from the exhaust pipe 21. This simplifies the assembly and disassembly of the heating pipe 3, improving ease of installation and removal.

[0079] Furthermore, such as Figure 2 , Figure 7As shown, there are two card slots 12132, symmetrically arranged on the base 1213. The positioning seat 121 has a guide hole, through which the card connector 32 enters and engages with the card slot 12132. Two card connectors 32 and two operating components 33 are each provided to correspond to the two card slots 12132. The two card connectors 32 are respectively positioned corresponding to the two card slots 12132, and the two operating components 33 are respectively connected to the two card connectors 32.

[0080] By symmetrically arranging the two slots 12132 and correspondingly engaging the two locking pieces 32 with the two slots 12132 respectively, the heating pipe 3 can be locked from both sides, thereby improving the connection stability of the heating pipe 3 after assembly. Simultaneously, the guide holes guide the insertion direction of the locking pieces 32, ensuring they accurately enter the corresponding slots 12132, thus improving the reliability of the locking engagement. Two operating pieces 33 are respectively positioned corresponding to the two locking pieces 32, allowing operators to manipulate the locking pieces 32 on both sides, facilitating the release of the locking constraints on both sides and reducing the difficulty of disassembling the heating pipe 3.

[0081] Those skilled in the art should understand that the connection method between the heating pipe 3 and the positioning seat 121 is not limited to the above-described embodiments. For example, the snap-fit ​​member 32 and the operating member 33 can be disposed on the positioning seat 121, and the slot 12132 can be disposed on the heating pipe 3. The snap-fit ​​member 32 and the slot 12132 cooperate to realize the snap-fit ​​between the heating pipe 3 and the positioning seat 121; the operating member 33 drives the snap-fit ​​member 32 to move, thereby disengaging the snap-fit ​​member 32 from the slot 12132, thereby realizing the disassembly of the heating pipe 3.

[0082] As a preferred example under specific example 3, such as Figure 3 , Figure 6 As shown, the host 1 is equipped with a stop member, which is used to limit the rotation angle of the positioning seat 121.

[0083] By setting a stop member in the main unit 1 and using the stop member to limit the rotation angle of the positioning seat 121, the positioning seat 121 can rotate within a preset angle range during rotation. This avoids the positioning seat 121 rotating too much and affecting its cooperation with the air outlet pipe 21. At the same time, it helps to keep the positioning seat 121 within an angle range suitable for cooperation with the air outlet pipe 21, thereby improving the reliability of the rotation of the positioning seat 121 and its cooperation with the air outlet pipe 21.

[0084] Furthermore, such as Figure 3 , Figure 5 , Figure 8The host 1 shown includes an upper housing 18 and a lower housing 19 that cooperates with the upper housing 18. The upper housing 18 and the lower housing 19 cooperate to form a receiving cavity 11. The upper housing 18 is provided with a mounting hole 13 for mounting a positioning seat 121. The outer shell 1214 is mounted on the upper surface of the upper housing 18.

[0085] The upper housing 18 and lower housing 19 cooperate to form a receiving cavity 11, allowing the humidifier 2 to be installed within the receiving cavity 11 formed by the upper housing 18 and lower housing 19. Simultaneously, a mounting hole 13 is provided in the upper housing 18, allowing the positioning seat 121 to be assembled with the main unit 1 through the mounting hole 13, thus realizing the installation and positioning of the positioning seat 121. Furthermore, an outer shell 1214 is provided on the upper surface of the upper housing 18, placing the outer shell 1214 outside the receiving cavity 11. This facilitates the assembly, disassembly, and maintenance of the outer shell 1214, while preventing the outer shell 1214 from occupying internal space in the receiving cavity 11, thereby improving the utilization rate of the internal space of the main unit 1.

[0086] Those skilled in the art will understand that the specific structural form of the host 1 can be set according to actual needs and is not limited to a structure formed by the cooperation of the upper housing 18 and the lower housing 19. For example, the host 1 may include a left housing and a right housing arranged in the left-right direction and cooperating with each other, or it may include multiple housing components and form the host 1 by snap-fit ​​or other connection methods; or the host 1 may also adopt an integral structure.

[0087] Furthermore, such as Figure 5 , Figure 8 As shown, one of the upper surfaces of the outer shell 1214 and the upper shell 18 is provided with a first guide groove 12142, and the other is provided with a first guide protrusion 181 that mates with the first guide groove 12142; and / or, one of the lower surfaces of the base 1213 and the upper shell 18 is provided with a second guide groove 12133, and the other is provided with a second guide protrusion 182 that mates with the second guide groove 12133. Preferably, the upper surface of the upper shell 18 is provided with a bearing groove 183 around the mounting hole 13, and the first guide groove 12142 or the first guide protrusion 181 is disposed in the bearing groove 183, and the outer contour of the outer shell 1214 mates with the bearing groove 183.

[0088] By providing a first guide groove 12142 and a first guide protrusion 181 that cooperate with each other between the outer shell 1214 and the upper surface of the upper shell 18, the first guide protrusion 181 can move along the first guide groove 12142 when the outer shell 1214 rotates relative to the upper shell 18, thereby guiding and limiting the rotation of the outer shell 1214. Similarly, by providing a second guide groove 12133 and a second guide protrusion 182 that cooperate with each other between the base 1213 and the lower surface of the upper shell 18, the second guide protrusion 182 can move along the second guide groove 12133 when the base 1213 rotates relative to the upper shell 18. Thus, the first guide groove 12142 and the first guide protrusion 181, and the second guide groove 12133 and the second guide protrusion 182 can respectively guide the rotation of the positioning seat 121 from both sides, so that the positioning seat 121 can rotate stably along a predetermined trajectory, reducing the deviation or shaking during the rotation process, thereby improving the rotational stability of the positioning seat 121.

[0089] Furthermore, such as Figure 5 , Figure 7 , Figure 8 As shown, one end of the base 1213 is mounted on the lower surface of the upper housing 18, and the other end passes through the mounting hole 13 and protrudes from the upper surface of the upper housing 18. The base 1213 includes a main body segment 12134 and a connecting segment 12135 connected to the main body segment 12134. The main body segment 12134 protrudes from the upper surface of the upper housing 18 through the mounting hole 13. The connecting segment 12135 is provided with a second guide groove 12133, and the lower surface of the upper housing 18 is provided with a second guide protrusion 182 that mates with the second guide groove 12133. The outer shell 1214 is snapped into the main body segment 12134. The connecting segment 12135 is provided with a locking groove 1212 that mates with the locking member 14.

[0090] By having the base 1213 penetrate the upper housing 18, the main body section 12134 and the connecting section 12135 of the base 1213 are located on both sides of the upper housing 18, thus providing stable rotational support for the base 1213. The connecting section 12135 cooperates with the second guide protrusion 182 through the second guide groove 12133, so that the base 1213 is guided and constrained during rotation, thereby improving the rotational stability of the positioning seat 121. The outer shell 1214 is connected to the main body section 12134 exposed on the upper surface of the upper housing 18, so that the outer shell 1214 is located on the outside of the upper housing 18. On the one hand, it is convenient to disassemble and assemble the outer shell 1214 and the base 1213. On the other hand, when it is necessary to inspect and maintain the positioning seat 121, the outer shell 1214 can be disassembled from the outside of the main unit 1, thereby facilitating the inspection, maintenance or replacement of the relevant components inside the positioning seat 121. Meanwhile, by providing a locking groove 1212 on the connecting section 12135, the locking groove 1212 cooperates with the locking member 14 to limit the rotation of the base 1213, so that the positioning seat 121 can rotate or remain locked according to the usage requirements, thereby improving the reliability of the positioning seat 121 during use.

[0091] In this application, the rotation limit setting of the base 1213 can be any of the following examples: Example 1: The stop member includes two abutments disposed on the lower surface of the upper housing 18. The two abutments are spaced apart along the rotation direction of the base 1213, and the abutments are used to abut against the base 1213. Further, the abutments are disposed in the second guide groove 12133, and the abutments abut against the second guide protrusion 182.

[0092] Example 2: The stop member includes two abutments disposed on the upper surface of the upper housing 18. The two abutments are spaced apart along the rotation direction of the base 1213, and the abutments are used to abut against the outer housing 1214. Further, the abutments are disposed in the first guide groove 12142, and the abutments abut against the first guide protrusion 181.

[0093] Preferably, in Examples 1 and 2, the abutment is detachably disposed in the first guide groove 12142 and the second guide groove 12133, and the rotation range can be adjusted by replacing the abutment with different specifications. Abutments can be disposed in both the first guide groove 12142 and the second guide groove 12133.

[0094] Those skilled in the art will understand that, in addition to the above-described configuration, the stop member can also be configured as the sidewall of the first guide groove 12142 and / or the second guide groove 12133, and the rotation angle of the positioning seat 121 can be controlled by controlling the length of the guide groove or the length of the guide protrusion; or the stop member can be configured on the rotation path of the base 1213 and located on the outer side of the base 1213, with the stop member abutting against the outer contour of the base 1213.

[0095] By providing two abutment members spaced apart along the rotation direction of the base 1213 on the lower surface of the upper housing 18, the base 1213 can abut against the corresponding abutment members when it rotates to different positions, thereby limiting the forward and reverse rotation range of the base 1213 and preventing the base 1213 from rotating too much. At the same time, the two abutment members limit the rotation range of the base 1213, allowing the positioning seat 121 to rotate within a predetermined angle range, thereby improving the stability of the positioning seat 121 during rotation.

[0096] As a preferred embodiment of this application, such as Figure 1 , Figure 4 As shown, the humidifier 2 includes an assembly section 25 and a limiting section 26. The assembly section 25 extends into the receiving cavity 11, and the air outlet pipe 21 is disposed in the assembly section 25. The limiting section 26 is connected to the assembly section 25 and is used to abut against the main unit 1.

[0097] By setting the assembly section 25 and the limiting section 26, the assembly section 25 can extend into the receiving cavity 11 and cooperate with the receiving cavity 11. At the same time, the limiting section 26 abuts against the main unit 1 to limit the installation position of the humidifier 2, so as to prevent the humidifier 2 from extending too far into the receiving cavity 11, thereby ensuring the accuracy of the installation position of the humidifier 2.

[0098] Furthermore, such as Figure 1 , Figure 6 As shown, the main unit 1 is provided with an air outlet 113, the assembly section 25 is provided with a docking interface that connects to the air outlet 113, the humidifier 2 is installed into the receiving cavity 11, and the air outlet 113 connects to the docking interface.

[0099] By connecting the air outlet 113 of the main unit 1 with the interface of the assembly section 25, the air path connection can be established simultaneously during the installation of the humidifier 2 into the receiving cavity 11, thereby reducing additional air path connection operations, improving the assembly convenience of the humidifier 2, and ensuring that the gas can stably enter the humidifier 2.

[0100] Furthermore, such as Figure 3 , Figure 4 As shown, one of the inner wall of the receiving cavity 11 and the assembly section 25 is provided with a guide protrusion 251, and the other is provided with a guide groove 114 that cooperates with the guide protrusion 251.

[0101] By guiding the protrusion 251 and the guide groove 114, the humidifier 2 is guided and constrained during the process of being installed into the receiving cavity 11, so that the assembly section 25 can enter the receiving cavity 11 in a predetermined direction, which is conducive to the accurate docking of the air outlet pipe 21, the interface and the related structure of the main unit 1, thereby improving the assembly accuracy and stability of the humidifier 2.
