Description

Technical Field

[0001] This application belongs to the technical field of medical devices, specifically relating to an electrical connector for a humidification therapy device and the humidification therapy device itself. Background Technology

[0002] Humidification therapy equipment plays a vital role in the medical field, primarily used to provide patients with a humidified and heated treatment environment to improve their respiratory condition and enhance their comfort.

[0003] Currently, humidification therapy equipment generally includes a main unit, a humidifier, and an electrical adapter. The main unit has an air outlet and electrical connection terminals. The electrical adapter has an air inlet channel and an air outlet channel. The air inlet end of the air inlet channel is connected to the air outlet, the air outlet end of the air inlet channel is connected to the air inlet end of the humidifier, the air outlet end of the air outlet channel is connected to the air outlet end of the humidifier, and the air outlet end of the air outlet channel is connected to the heating pipeline. The heating pipeline is electrically connected to the main unit through the electrical adapter, so that the gas flowing out of the air outlet enters the humidifier through the air inlet channel, so that the humidifying liquid in the humidifier humidifies the gas. Then, the humidified gas enters the heating pipeline through the air outlet channel to heat the humidified gas. However, since the existing electrical connection terminals are connected to the circuit board inside the main unit via mating terminals, when the electrical adapter is disassembled, the electrical connection terminals will apply force to the mating terminals, causing the mating terminals to move and potentially damaging them, thus affecting the service life of the humidification therapy equipment. At the same time, the electrical connection terminals are usually integrated into the air outlet, making it impossible to replace the electrical connection terminals and the air outlet separately, which increases the maintenance cost of the humidification therapy equipment. Furthermore, in order to avoid contamination of the air outlet by the electrical connection terminals during the production of the air outlet, the manufacturing process of the air outlet is relatively complex, which in turn increases the production cost and difficulty of the air outlet. Utility Model Content

[0004] This application provides an electrical connector for a humidification therapy device to extend the service life of the humidification therapy device, reduce the maintenance cost of the humidification therapy device, and reduce the production cost of the vent connector.

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

[0006] An electrical connector for a humidification therapy device, the humidification therapy device including a housing, the electrical connector disposed within the housing, and including an input terminal located inside the housing and an output terminal located outside the housing, the electrical connector comprising:

[0007] Mounting base, the mounting base having an air outlet, and the side of the air outlet having a mounting opening;

[0008] An electrical connection terminal is provided at the mounting port;

[0009] A one-way valve, at least a portion of which extends into the outlet.

[0010] By adopting the above technical solution, since the electrical connection terminal in this application is located at the mounting port, the electrical connection terminal and the air outlet are separated, allowing for individual replacement of the air outlet and the electrical connection terminal, thereby reducing maintenance costs. It also avoids contamination of the air outlet by the electrical connection terminal during production, reducing the process requirements for electrical connector production, lowering the production difficulty of electrical connectors, improving production efficiency, and reducing production costs. Furthermore, the electrical connection terminal can be electrically connected to the circuit board via wires, ensuring that the force point of the electrical connection terminal is on the mounting base when disassembling the electrical adapter, preventing the connection position between the electrical connection terminal and the circuit board from shaking during disassembly. This ensures the connection stability between the electrical connection terminal and the circuit board, thereby extending the service life of the humidification therapy equipment.

[0011] Optionally, the electrical connector further includes a sealing element, which has a first sealing port corresponding to the air outlet and a second sealing port corresponding to the mounting port, and the electrical connection terminal is sequentially disposed in the mounting port and the second sealing port.

[0012] By adopting the above technical solution, since the sealing element has a first sealing port corresponding to the air outlet, it can seal the gap between the electrical adapter and the air outlet, thereby increasing the airtightness between the electrical adapter and the air outlet and controlling the leakage between the electrical adapter and the air outlet within a reasonable range, thus increasing the gas delivery efficiency. Since the sealing element has a second sealing port corresponding to the mounting port, the electrical connection terminals are sequentially inserted through the mounting port and the second sealing port, which allows the sealing element to also seal the electrical connection terminals, thereby preventing short circuits in the humidification therapy equipment and preventing dirt from entering the electrical connection terminals, ensuring the normal operation of the humidification therapy equipment and further extending its service life.

[0013] Optionally, the seal is located on the side where the output end is located, and the seal forms a sealing end face, with the first sealing port and the second sealing port both located within the area formed by the sealing end face.

[0014] By adopting the above technical solution, since both the first sealing port and the second sealing port are located in the area formed by the sealing end face, on the one hand, the contact area between the electrical adapter and the air outlet and the electrical connection terminal can be increased, thereby increasing the connection stability between the electrical adapter and the air outlet and the electrical connection terminal; on the other hand, the electrical adapter can be fully in contact with the sealing element, thereby ensuring the sealing performance between the electrical adapter and the sealing element.

[0015] Optionally, the seal includes a sealing rib formed around the sealing end face.

[0016] By adopting the above technical solution, since the sealing element includes a sealing rib formed around the sealing end face, the sealing rib can guide water so that water or dirt moves along the rib to the side away from the mounting base, thereby preventing water from entering between the sealing element and the mounting base. This further avoids short circuits in the humidification therapy equipment, thereby increasing the safety of the humidification therapy equipment and extending its service life.

[0017] Optionally, the mounting base is provided with a connecting hole, the sealing element is provided with a connecting post, the connecting post is provided with an elastic stop portion, the elastic stop portion can pass through the connecting hole and cooperate with the stop of the mounting base.

[0018] By adopting the above technical solution, when installing the seal, first align the seal with the mounting base so that the connecting post is aligned with the connecting hole. Then, apply pressure to the seal towards the mounting base, and the connecting post extends into the connecting hole. Next, apply a pulling force away from the mounting base to the end of the connecting post that passes through the connecting hole. The elastic stop undergoes elastic deformation under the pressure of the hole wall, allowing the elastic stop to pass through the connecting hole. Subsequently, the elastic stop recovers its deformation and cooperates with the stop on the side of the mounting base away from the seal to complete the installation of the seal. In summary, when installing the seal, only pressure towards the mounting base needs to be applied to the seal, thereby reducing the difficulty of seal installation, improving the efficiency of seal installation, and increasing the connection stability between the seal and the mounting base to ensure the sealing effect of the seal on the electrical connection terminals and the vent.

[0019] Optionally, the mounting base has a mounting step, and the seal has a sealing opening that is interference-fitted with the mounting step.

[0020] By adopting the above technical solution, since the mounting base has an installation step and the seal has a sealing opening that is interference-fitted with the installation step, after the seal is installed on the mounting base, the installation step is located inside the sealing opening, and the wall of the sealing opening is interference-fitted with the periphery of the installation step. This increases the connection stability between the seal and the mounting base on the one hand, and increases the contact area between the seal and the mounting base on the other hand, thereby increasing the sealing performance between the seal and the mounting base. This further increases the safety of the humidification therapy equipment and extends its service life.

[0021] Optionally, the air outlet is provided with a positioning part, and the one-way valve is provided with a guide part, the guide part being able to cooperate with the positioning part to guide and position the one-way valve.

[0022] By adopting the above technical solution, when installing the check valve, first align the check valve with the outlet, and simultaneously align the guide part with the positioning part. Then, apply a force towards the outlet to the check valve so that the guide part extends into the positioning part. This allows the cooperation between the guide part and the positioning part to guide the check valve, enabling it to move precisely to the required installation position. At the same time, the cooperation between the guide part and the positioning part can also position the check valve to prevent it from rotating relative to the outlet around its circumference, thereby increasing the connection stability between the check valve and the outlet.

[0023] Optionally, the one-way valve includes a valve body and a fixing part. The inner wall of the air outlet is provided with a stop rib. The fixing part is engaged with the mounting base. The stop rib abuts against the valve body to fix the one-way valve relative to the air outlet.

[0024] By adopting the above technical solution, the one-way valve is fixedly installed on the mounting seat due to the snap-fit ​​between the fixing part and the mounting base and the stop rib abutting against the valve body, thereby increasing the stability of the one-way valve. At the same time, the setting of the fixing part and the stop rib simplifies the structural design of the one-way valve and the mounting seat, reduces the production difficulty of the mounting seat and the one-way valve, and thus reduces the production cost of the electrical connector.

[0025] Optionally, the electrical connector further includes a connecting element communicating with the one-way valve, the one-way valve having a flange located between the connecting element and the mounting base, the connecting element being connected to the mounting base to press and secure the one-way valve.

[0026] By adopting the above technical solution, since the check valve has a flange located between the connecting part and the mounting base, and the connecting part is connected to the mounting base, the check valve can be fixed by the compression of the flange by the connecting part, thereby increasing the stability of the check valve. At the same time, it can also simplify the structural design of the check valve, thereby reducing the production difficulty of the check valve and thus reducing the production cost of the electrical connector.

[0027] Optionally, the one-way valve includes a valve body and a diaphragm sleeve fitted onto the valve body. The diaphragm sleeve includes a connecting sleeve and a diaphragm disposed on the connecting sleeve. The diaphragm has a connecting end connected to the connecting sleeve and a free end opposite to the connecting end. The connecting end is provided with a support groove, and the valve body is provided with a support rib extending into the support groove.

[0028] By adopting the above technical solution, since the connection end is provided with a support groove and the valve body is provided with a support rib extending into the support groove, when the diaphragm deforms, the support rib can support the groove wall of the support groove to increase the diaphragm's ability to recover its deformation. This makes it easier for the diaphragm to recover its deformation, thus ensuring the diaphragm sleeve's closing effect on the valve body. This also prevents external dirt from entering the main unit through the valve body, thereby ensuring the cleanliness of the humidification therapy equipment.

[0029] Optionally, the valve body is provided with a limiting rib, which can abut against one end of the connecting sleeve to prevent the connecting sleeve from coming off to the side where the output end is located.

[0030] By adopting the above technical solution, since the limiting rib can abut one end of the connecting sleeve, the cooperation between the limiting rib and the connecting sleeve can limit the connecting sleeve, so as to prevent the connecting sleeve from separating from the valve body at the end near the output end. This increases the connection stability between the connecting sleeve and the valve body, and further increases the stability of the one-way valve, so as to further prevent external dirt from entering the main unit through the one-way valve, and further ensure the cleanliness of the humidification therapy equipment.

[0031] Optionally, the mounting base is provided with a mounting channel, one end of which forms the mounting opening. The electrical connection terminal is provided with a snap-fit ​​part, and the side wall of the mounting channel is provided with a mating part that snaps into the snap-fit ​​part, so as to fix the electrical connection terminal by means of the snap-fit ​​part and the mating part.

[0032] By adopting the above technical solution, since an installation opening is formed at one end of the installation channel, and the electrical connection terminal is then installed on the mounting base, the electrical connection terminal passes through the installation channel to increase the contact area between the electrical connection terminal and the mounting base, thereby increasing the connection stability between the electrical connection terminal and the mounting base. At the same time, the electrical connection terminal is provided with a snap-fit ​​part, and the side wall of the installation channel is provided with a mating part that snaps into the snap-fit ​​part. This achieves the fixation of the electrical connection terminal by utilizing the snap-fit ​​part and the mating part, so as to fix the electrical connection terminal while it is passing through the installation channel, thereby reducing the difficulty of fixing the electrical connection terminal and greatly improving the installation efficiency of the electrical connection terminal. Furthermore, it can further increase the connection stability between the electrical connection terminal and the mounting base.

[0033] Optionally, the electrical connection terminal is provided with a mating rib, which can be mated with the end wall or the opening of the mounting channel.

[0034] By adopting the above technical solution, since the mating rib can cooperate with the end wall or the stop at the opening of the installation channel, the mating rib and the stop of the installation channel can limit the electrical connection terminal, thereby increasing the stability of the electrical connection terminal and ensuring the connection stability between the electrical connection terminal and the electrical adapter, thus ensuring the stability of the humidification therapy equipment during operation and improving the user experience.

[0035] This application also discloses a humidification therapy device to extend the service life of the humidification therapy device and reduce the production difficulty and cost of the humidification therapy device.

[0036] A humidification therapy device, comprising:

[0037] The host computer has a casing;

[0038] Humidification components;

[0039] An electrical connector, wherein the electrical connector is disposed in the housing, and the electrical connector is selected from the electrical connectors described above;

[0040] An electrical adapter has an air inlet pipe and an air outlet pipe. The air inlet pipe has a first port connected to the air outlet and a second port connected to the air inlet pipe of the humidifying component. The first port has air inlet electrical terminals on both sides that are electrically connected to the electrical connection terminals. One end of the air outlet pipe is connected to the air outlet pipe of the humidifying component, and the other end is used to connect to the heating pipe.

[0041] By adopting the above technical solution, since the humidification therapy device in this application uses the aforementioned electrical connector, the electrical connection terminal and the air outlet can be replaced separately, thereby reducing the maintenance cost of the humidification therapy device. At the same time, it also reduces the requirements for the manufacturing process of the electrical connector, thereby reducing the manufacturing difficulty and cost of the electrical connector, thus reducing the production cost of the humidification therapy device. Furthermore, when disassembling the electrical adapter, the stress point of the electrical connection terminal is located at the mounting base, so as to ensure the connection stability between the electrical connection terminal and the internal circuit board of the main unit, thereby extending the service life of the humidification therapy device.

[0042] Optionally, the mounting base is a recessed seat, and the edge of the seat is integrally formed with the outer shell.

[0043] By adopting the above technical solution, since the edge of the base is integrally formed with the outer shell, the connection stability between the mounting base and the outer shell is increased, thereby ensuring the stability of the electrical connection terminals and the one-way valve; and the number of parts required to be assembled when assembling the humidification therapy equipment is reduced, thereby improving the production efficiency of the humidification therapy equipment.

[0044] Optionally, the housing forms an opening, at least a portion of the mounting base extends through the opening, and the mounting base is connected to the housing by fasteners.

[0045] By adopting the above technical solution, since at least part of the mounting base is inserted through the opening and the mounting base is connected to the housing by fasteners, the structural design of the housing is simplified, which facilitates the production of the housing and improves the production efficiency of the housing. It also enables the individual replacement of the mounting base to reduce the maintenance cost of the humidification therapy equipment and improve the user experience.

[0046] Optionally, the electrical connector further includes a seal with a periphery forming an edge located between the mounting base and the housing, so as to secure the seal by compression of the edge by the mounting base and the housing.

[0047] By adopting the above technical solution, since the periphery of the seal forms an edge located between the mounting base and the housing, the seal can be fixed by the compression of the edge by the mounting base and the housing, thereby increasing the stability of the seal and ensuring the sealing effect of the seal on the air outlet and electrical connection terminals. At the same time, it also reduces the installation difficulty of the seal, thereby improving the assembly efficiency of the humidification therapy equipment. In addition, it increases the sealing between the seal and the mounting base to prevent water or dirt from entering the main unit through the gap between the mounting base and the housing, thereby further extending the service life of the humidification therapy equipment.

[0048] Optionally, the electrical connector further includes a sealing element, which has a first sealing port corresponding to the air outlet and a second sealing port corresponding to the mounting port. The electrical connection terminal is sequentially inserted through the mounting port and the second sealing port. The sealing element forms a sealing end face, and both the first sealing port and the second sealing port are located within the area formed by the sealing end face. A seal is formed between the first port of the electrical adapter and the first sealing port, and a seal is formed between the end of the electrical adapter and the sealing end face.

[0049] By adopting the above technical solution, a seal is formed between the first port of the electrical converter and the first sealing port, thereby increasing the sealing performance of the connection between the electrical converter and the air outlet to ensure the efficiency of gas delivery; and a seal is formed between the end of the electrical converter and the sealing end face, thereby increasing the sealing performance between the electrical converter and the mounting base to prevent water from flowing through the gap between the electrical converter and the mounting base to the electrical connection terminal and contacting the electrical connection terminal, thus avoiding short circuits in the humidification therapy equipment and extending the service life of the humidification therapy equipment.

[0050] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0051] 1. The electrical connector in this application includes a mounting base, an electrical connection terminal, and a one-way valve. The mounting base has an air outlet, and a mounting port is provided on the side of the air outlet. The electrical connection terminal is located in the mounting port, and at least a portion of the one-way valve extends into the air outlet. This achieves separate installation of the electrical connection terminal and the air outlet, allowing for individual replacement of the air outlet and the electrical connection terminal, thereby reducing maintenance costs. It also prevents the electrical connection terminal from contaminating the air outlet during production, reducing the process requirements for manufacturing the electrical connector, lowering the manufacturing difficulty, increasing production efficiency, and reducing production costs. Furthermore, the electrical connection terminal can be electrically connected to the circuit board via a wire, ensuring that the stress point of the electrical connection terminal is on the mounting base when disassembling the electrical adapter, preventing the connection position between the electrical connection terminal and the circuit board from shaking during disassembly. This ensures the stability of the connection between the electrical connection terminal and the circuit board, thereby extending the service life of the humidification therapy equipment.

[0052] 2. The electrical connector in this application also includes a sealing element. The sealing element has a first sealing port corresponding to the air outlet and a second sealing port corresponding to the mounting port. The electrical connection terminals are sequentially inserted through the mounting port and the second sealing port, thereby enabling the sealing element to seal the gap between the electrical adapter and the air outlet, thus increasing the airtightness between the electrical adapter and the air outlet and controlling the leakage between the electrical adapter and the air outlet within a reasonable range, thereby increasing the gas delivery efficiency. At the same time, the sealing element can also seal the electrical connection terminals to prevent short circuits in the humidification therapy equipment and to prevent dirt from entering the electrical connection terminals, thus ensuring the normal operation of the humidification therapy equipment and further extending the service life of the humidification therapy equipment.

[0053] 3. In this application, the sealing element forms a sealing end face, and the first sealing port and the second sealing port are both located in the area formed by the sealing end face. On the one hand, this can increase the contact area between the electrical adapter and the air outlet and the electrical connection terminal, thereby increasing the connection stability between the electrical adapter and the air outlet and the electrical connection terminal. On the other hand, it allows the electrical adapter to fully contact the sealing element, thereby ensuring the sealing performance between the electrical adapter and the sealing element.

[0073] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0074] Many specific details are set forth in the following description in order to provide a full 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.

[0075] 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.

[0076] 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. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0077] In this application, unless otherwise expressly specified and limited, the "above" or "below" of the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. In the description of this specification, references to terms such as "implementation," "example," "a particular embodiment," "example," or "specific example," etc., indicate that the specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. 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.

[0078] Reference Figures 1 to 14 An electrical connector for a humidification therapy device is disclosed, wherein the humidification therapy device includes a housing 1, the electrical connector is disposed on the housing 1, and the electrical connector includes an input terminal located inside the housing 1 and an output terminal located outside the housing 1; the electrical connector includes a mounting base 2, an electrical connection terminal 3, and a one-way valve 4, the mounting base 2 has an air outlet 21, and the side of the air outlet 21 is provided with a mounting port 22; the electrical connection terminal 3 is disposed in the mounting port 22; at least a portion of the one-way valve 4 extends into the air outlet 21.

[0079] Specifically, an installation port 22 is provided on both sides of the air outlet 21.

[0080] Because the electrical connection terminal 3 in this application is located at the mounting port 22, the electrical connection terminal 3 and the air outlet 21 are separated, allowing for individual replacement of both the air outlet 21 and the electrical connection terminal 3. This reduces maintenance costs and prevents the electrical connection terminal 3 from contaminating the air outlet 21 during production. This also reduces the process requirements for manufacturing electrical connectors, lowers production difficulty, increases production efficiency, and reduces production costs. Furthermore, this electrical connector can simultaneously provide both air and electrical connectivity, facilitating the installation and removal of the electrical adapter 8 and simplifying user operation.

[0081] In addition, the electrical connection terminal 3 can be electrically connected to the circuit board via a wire, so that when the electrical adapter 8 is disassembled, the force point of the electrical connection terminal 3 is on the mounting base 2, which avoids the phenomenon of the connection position between the electrical connection terminal 3 and the circuit board shaking when the electrical adapter 8 is disassembled, thereby ensuring the connection stability between the electrical connection terminal 3 and the circuit board, and thus extending the service life of the humidification therapy equipment.

[0082] In a preferred embodiment, refer to Figure 2 and Figure 11 The electrical connector also includes a sealing element 5, which has a first sealing port 51 corresponding to the air outlet 21 and a second sealing port 52 corresponding to the mounting port 22. The electrical connection terminal 3 is sequentially inserted through the mounting port 22 and the second sealing port 52.

[0083] Because the sealing element 5 has a first sealing port 51 corresponding to the air outlet 21, the sealing element 5 can seal the gap between the electrical adapter 8 and the air outlet 21, thereby increasing the airtightness between the electrical adapter 8 and the air outlet 21 and controlling the leakage between the electrical adapter 8 and the air outlet 21 within a reasonable range, thus increasing the gas delivery efficiency. Because the sealing element 5 has a second sealing port 52 corresponding to the mounting port 22, the electrical connection terminal 3 is sequentially inserted through the mounting port 22 and the second sealing port 52, thereby the sealing element 5 can also seal the electrical connection terminal 3 to avoid short circuits in the humidification therapy equipment and to prevent dirt from entering the electrical connection terminal 3, thus ensuring the normal operation of the humidification therapy equipment and further extending its service life.

[0084] Furthermore, the sealing element 5 is located on the side where the output end is located. The sealing element 5 forms a sealing end face. The first sealing port 51 and the second sealing port 52 are both located in the area formed by the sealing end face. On the one hand, this can increase the contact area between the electrical adapter 8 and the air outlet 21 and the electrical connection terminal 3, thereby increasing the connection stability between the electrical adapter 8 and the air outlet 21 and the electrical connection terminal 3. On the other hand, it allows the electrical adapter 8 to fully contact the sealing element 5, thereby ensuring the sealing between the electrical adapter 8 and the sealing element 5.

[0085] Furthermore, refer to Figure 4 The seal 5 includes a sealing rib 53 formed around the sealing end face, which guides water to move along the rib to the side away from the mounting base 2, preventing water from entering between the seal 5 and the mounting base 2. This further prevents short circuits in the humidification therapy equipment, thereby increasing its safety and extending its service life. Simultaneously, the sealing rib 53 also guides and restricts the installation of the electrical adapter 8.

[0086] In a preferred embodiment, refer to Figure 4 and Figure 5 The mounting base 2 is provided with a connecting hole 23, and the sealing element 5 is provided with a connecting post 54. The connecting post 54 is provided with an elastic stop part 541. The elastic stop part 541 can pass through the connecting hole 23 and cooperate with the stop of the mounting base 2.

[0087] When installing the seal 5, first align the seal 5 with the mounting base 2 so that the connecting post 54 is aligned with the connecting hole 23. Then, apply pressure to the seal 5 toward the mounting base 2, and then the connecting post 54 extends into the connecting hole 23. Next, apply a pulling force away from the mounting base to the end of the connecting post 54 that extends out of the connecting hole 23. The elastic stop part 541 undergoes elastic deformation under the pressure of the hole wall of the connecting hole 23, so that the elastic stop part 541 passes through the connecting hole 23. Then, the elastic stop part 541 recovers its deformation and cooperates with the stop on the side of the mounting base 2 away from the seal 5 to complete the installation of the seal 5.

[0088] In summary, when installing the seal 5, only pressure needs to be applied to the seal 5 towards the mounting base 2, thereby reducing the difficulty of installing the seal 5, improving the installation efficiency of the seal 5, and increasing the connection stability between the seal 5 and the mounting base 2, so as to ensure the sealing effect of the seal 5 on the electrical connection terminal 3 and the air outlet 21.

[0089] This application does not specifically limit the structure of the elastic stop portion 541; preferably, refer to... Figure 4The elastic stop portion 541 is an annular structure that extends continuously along the circumference of the connecting post 54 to increase the stop mating area between the elastic stop portion 541 and the mounting base 2, thereby increasing the connection stability between the seal 5 and the mounting base 2.

[0090] The better one is to refer to Figure 4 The diameter of the elastic stop portion 541 gradually increases along the direction close to the seal 5. That is, the diameter of the end of the elastic stop portion 541 away from the seal 5 is smaller than the diameter of the end close to the seal 5. This allows the end of the elastic stop portion 541 away from the seal 5 to be more easily inserted into the connection hole 23 when the seal 5 is installed, thereby reducing the force required to install the seal 5 and facilitating the installation of the seal 5, thus improving the installation efficiency of the seal 5.

[0091] In other embodiments, the resilient stop 541 may also be a block structure or other shaped structure provided on the connecting post 54.

[0092] In a preferred embodiment, refer to Figure 11 The mounting base 2 has a mounting step 24, and the sealing element 5 has a sealing opening that is interference-fitted with the mounting step 24. That is, after the sealing element 5 is installed on the mounting base 2, the mounting step 24 is located inside the sealing opening, and the wall of the sealing opening is interference-fitted with the periphery of the mounting step 24. This increases the connection stability between the sealing element 5 and the mounting base 2, and also increases the contact area between the sealing element 5 and the mounting base 2, thereby increasing the sealing performance between the sealing element 5 and the mounting base 2. This further increases the safety of the humidification therapy device and extends its service life.

[0093] In a preferred embodiment, refer to Figure 5 , Figure 6 , Figure 12 and Figure 13 The air outlet 21 is provided with a positioning part 211, and the one-way valve 4 is provided with a guide part 411. The guide part 411 can cooperate with the positioning part 211 to guide and position the one-way valve 4.

[0094] When installing the check valve 4, first align the check valve 4 with the outlet 21, and simultaneously align the guide part 411 with the positioning part 211. Then, apply a force to the check valve 4 in the direction of the outlet 21 so that the guide part 411 extends into the positioning part 211. This allows the cooperation between the guide part 411 and the positioning part 211 to guide the check valve 4, enabling it to move precisely to the required installation position. At the same time, the cooperation between the guide part 411 and the positioning part 211 can also position the check valve 4 to prevent it from rotating relative to the outlet 21 around its circumference, thereby increasing the connection stability between the check valve 4 and the outlet 21.

[0095] This application does not specifically limit the structure of the positioning part 211 and the guide part 411. Preferably, refer to Figure 5 , Figure 6 , Figure 12 and Figure 13 The inner wall of the air outlet 21 is provided with a stop rib 212, and the stop rib 212 is provided with a positioning notch, which forms a positioning part 211. The guide part 411 is a guide rib provided on the one-way valve 4 and can extend into the positioning notch, so as to guide and position the one-way valve 4 by means of the insertion and cooperation between the guide rib and the positioning notch. In other embodiments, the positioning part 211 can also be a rod-shaped structure provided on the inner wall of the air outlet 21, and the guide part 411 can be a hole structure provided on the one-way valve 4. After the one-way valve 4 is installed on the air outlet 21, the rod-shaped structure passes through the hole structure to guide and position the one-way valve 4.

[0096] This application does not specify a particular method for fixing the one-way valve 4, which can be any of the following embodiments:

[0097] Implementation Method 1, in this implementation method, refer to Figure 12 and Figure 13 The one-way valve 4 includes a valve body 41 and a fixing part 412. The inner wall of the air outlet 21 is provided with a stop rib 212. The fixing part 412 is engaged with the mounting base 2. The stop rib 212 abuts against the valve body 41 to fix the one-way valve 4 relative to the air outlet 21, thereby realizing the fixed installation of the one-way valve 4 on the mounting base 2 to increase the stability of the one-way valve 4. At the same time, the setting of the fixing part 412 and the stop rib 212 simplifies the structural design of the one-way valve 4 and the mounting base 2, reduces the production difficulty of the mounting base 2 and the one-way valve 4, and thus reduces the production cost of the electrical connector.

[0098] Specifically, the fixing part 412 is fixedly connected to the valve body 41 to improve the stability of the one-way valve 4.

[0099] This application does not specifically limit the structure of the fixing part 412; preferably, refer to... Figure 13The fixing part 412 is an L-shaped elastic arm, and a guide surface is provided at the end of the elastic arm away from the valve body 41. When the one-way valve 4 is installed into the air outlet 21, the guide surface can guide the deformation direction of the elastic arm, thereby facilitating the installation of the one-way valve 4 into the air outlet 21. In other embodiments, the fixing part 412 can also be a block structure or other structure provided on the valve body 41, as long as it can achieve the snap-fit ​​engagement between the valve body 41 and the mounting base 2.

[0100] Implementation Method Two: In this implementation method, refer to... Figure 2 , Figure 3 and Figure 7 The electrical connector also includes a connecting element 6 that communicates with the one-way valve 4. The one-way valve 4 has a flange 423 located between the connecting element 6 and the mounting base 2. The connecting element 6 is connected to the mounting base 2 to press and fix the one-way valve 4.

[0101] It should be noted that the connecting component 6 is connected to the gas-generating component inside the humidification therapy device, so that the gas generated inside the device is delivered to the one-way valve 4 via the connecting component 6.

[0102] Since the one-way valve 4 is fixed by the compression of the flange 423 by the connecting part 6 and the mounting base 2, the stability of the one-way valve 4 is increased. At the same time, the structural design of the one-way valve 4 is simplified, thereby reducing the production difficulty of the one-way valve 4 and thus reducing the production cost of the electrical connector.

[0103] Specifically, refer to Figure 7 and Figure 8 The flange 423 extends continuously along its circumference from the connecting sleeve 421 of the one-way valve 4 to increase the connection area with the connecting member 6 and the mounting base 2, thereby improving the fixing effect of the one-way valve 4. The connecting member 6 is fixedly connected to the mounting base 2 with screws to improve the fixing effect of the one-way valve 4. Of course, the connecting member 6 can also be fixedly connected to the mounting base 2 with other fasteners, such as snap-fit ​​posts, etc.

[0104] To ensure the closing effect of the one-way valve 4, this application may also employ any one or a combination of two of the following embodiments:

[0105] Implementation Method 1, in this implementation method, refer to Figure 6 and Figure 8 The one-way valve 4 includes a valve body 41 and a diaphragm sleeve 42 sleeved on the valve body 41. The diaphragm sleeve 42 includes a connecting sleeve 421 and a diaphragm 422 disposed on the connecting sleeve 421. The diaphragm 422 has a connecting end connected to the connecting sleeve 421 and a free end opposite to the connecting end. The connecting end is provided with a support groove 424. The valve body 41 is provided with a support rib 413 extending into the support groove 424.

[0106] Because the connecting end is provided with a support groove 424, and the valve body 41 is provided with a support rib 413 extending into the support groove 424, when the diaphragm 422 deforms, the support rib 413 can support the groove wall of the support groove 424 to increase the ability of the diaphragm 422 to recover its deformation, thereby making it easier for the diaphragm 422 to recover its deformation, so as to ensure the closing effect of the diaphragm sleeve 42 on the valve body 41, thereby preventing external dirt from entering the main unit through the valve body 41, so as to ensure the cleanliness of the humidification therapy equipment, and also increasing the response efficiency of the diaphragm 422 when closing the valve body 41.

[0107] Implementation Method Two: In this implementation method, refer to... Figure 14 The one-way valve 4 includes a valve body 41 and a diaphragm sleeve 42 sleeved on the valve body 41. The diaphragm sleeve 42 includes a connecting sleeve 421 and a diaphragm 422 disposed on the connecting sleeve 421. The diaphragm 422 has a connecting end connected to the connecting sleeve 421 and a free end opposite to the connecting end. A protrusion 425 is provided on the side of the connecting end away from the connecting sleeve 421. When the diaphragm 422 rotates around the connecting end to open the one-way valve 4, the protrusion 425 can abut against the wall of the air outlet 21, so that the protrusion 425 supports the diaphragm 422, thereby increasing the ability of the diaphragm 422 to recover its deformation. This makes it easier for the diaphragm 422 to recover its deformation, so as to ensure the closing effect of the diaphragm sleeve 42 on the valve body 41. This prevents external dirt from entering the main unit through the valve body 41, thereby ensuring the cleanliness of the humidification therapy equipment. At the same time, it also increases the response efficiency of the diaphragm 422 when closing the valve body 41.

[0108] In a preferred embodiment, refer to Figure 6 and Figure 13 The valve body 41 is provided with a limiting rib 414, which can abut against one end of the connecting sleeve 421 to prevent the connecting sleeve 421 from coming off to the side where the output end is located.

[0109] Specifically, the limiting rib 414 can abut against the end of the connecting sleeve 421 near the output end to block the connecting sleeve 421 in the outward direction, so as to prevent the connecting sleeve 421 from detaching from the valve body 41 at the end near the output end. This increases the connection stability between the connecting sleeve 421 and the valve body 41, thereby increasing the stability of the one-way valve 4. This further prevents external dirt from entering the main unit through the one-way valve 4, and further ensures the cleanliness of the humidification therapy equipment.

[0110] This application does not specify the formation method of the limiting rib 414; preferably, refer to Figure 6 and Figure 13The valve body 41 is provided with an annular groove extending circumferentially therein. A limiting rib 414 is formed on the wall of the annular groove near the output end. At least a portion of the connecting sleeve 421 is located within the annular groove, enabling a stop-fit ​​between the limiting rib 414 and the connecting sleeve 421 in the outward direction. Furthermore, the wall of the annular groove near the input end can also stop the movement of the connecting sleeve 421 in the inward direction, preventing the connecting sleeve 421 from disengaging from the valve body 41 on the side facing the input end. In other embodiments, the limiting rib 414 can also be a rib structure protruding from the outer circumferential surface of the valve body 41.

[0111] This application does not specify the fixing method of the electrical connection terminal 3. Preferably, refer to Figure 9 , Figure 10 and Figure 12 The mounting base 2 is provided with a mounting channel 25, one end of which forms a mounting opening 22. The electrical connection terminal 3 is provided with a snap-fit ​​part 31. The side wall of the mounting channel 25 is provided with a mating part 251 that snaps into the snap-fit ​​part 31, so as to fix the electrical connection terminal 3 by snapping into the snap-fit ​​part 31 and the mating part 251.

[0112] Since an installation opening 22 is formed at one end of the installation channel 25, the electrical connection terminal 3 is installed on the mounting base 2. The electrical connection terminal 3 passes through the installation channel 25 to increase the contact area between the electrical connection terminal 3 and the mounting base 2, thereby increasing the connection stability between the electrical connection terminal 3 and the mounting base 2. At the same time, the electrical connection terminal 3 is provided with a snap-fit ​​part 31, and the side wall of the installation channel 25 is provided with a mating part 251 that snaps into the snap-fit ​​part 31. This allows the electrical connection terminal 3 to be fixed by snapping into the mounting channel 25, thereby reducing the difficulty of fixing the electrical connection terminal 3 and greatly improving the installation efficiency of the electrical connection terminal 3. It can also further increase the connection stability between the electrical connection terminal 3 and the mounting base 2.

[0113] This application does not specifically limit the structure of the snap-fit ​​part 31 and the mating part 251. Preferably, refer to Figure 9 and Figure 10 The snap-fit ​​part 31 is a snap-fit ​​block located on the side of the electrical connection terminal 3, and the mating part 251 is a snap-fit ​​hole located on the side wall of the mounting channel 25. The snap-fit ​​block and the snap-fit ​​hole engage to fix the electrical connection terminal 3. In other embodiments, the snap-fit ​​part 31 can also be a hole structure on the side of the electrical connection terminal 3, and the mating part 251 is a block structure located on the side wall of the mounting channel 25. After the electrical connection terminal 3 is installed in the mounting channel 25, the block structure extends into the hole structure to achieve the snap-fit ​​engagement between the snap-fit ​​part 31 and the mating part 251.

[0114] Furthermore, refer to Figure 10 The electrical connection terminal 3 is provided with a mating rib 32, which can be mated with the end wall or the stop at the opening of the mounting channel 25.

[0115] Since the mating rib 32 can mate with the side wall stop of the mounting channel 25, the mating rib 32 and the stop of the mounting channel 25 can limit the electrical connection terminal 3, thereby increasing the stability of the electrical connection terminal 3 and ensuring the connection stability between the electrical connection terminal 3 and the electrical adapter 8, so as to ensure the stability of the humidification therapy equipment during operation, and thus improve the user experience.

[0116] The method of forming the installation channel 25 in this application is not specifically limited; it can be formed by a stepped hole (e.g., Figure 9 As shown), it can also be formed by straight-walled holes (such as...). Figure 12 (As shown); when the mounting channel 25 is formed by a stepped hole, the mating rib 32 engages with the end wall stop at the diameter change point of the mounting channel 25; when the mounting channel 25 is formed by a straight wall hole, the mating rib 32 engages with the wall stop at the channel opening of the mounting channel 25.

[0117] This application does not specify the installation method of the electrical connection terminal 3; it can be installed to the mounting base 2 along the direction from the output end to the input end of the electrical connector (e.g., Figure 11 As shown), it can also be installed in mounting base 2 (e.g., along the direction from the input end to the output end of the electrical connector). Figure 2 and Figure 9 (As shown); when the electrical connection terminal 3 is installed on the mounting base 2 along the direction from the output end to the input end of the electrical connector, the mounting base 2 can stop the movement of the mating rib 32 in the direction towards the input end, and the sealing member 5 can stop the movement of the mating member in the direction towards the output end, thereby increasing the stability of the electrical connection terminal 3; when the electrical connection terminal 3 is installed on the mounting base 2 along the direction from the input end to the output end of the electrical connector, the mounting base 2 can stop the movement of the mating rib 32 in the direction towards the output end, thereby preventing the electrical connection terminal 3 from detaching from the mounting base 2 in the direction towards the output end, thus increasing the stability of the electrical connection terminal 3.

[0118] In other embodiments, the electrical connection terminal 3 can also be connected to the mounting base 2 by other fixing methods such as screws.

[0119] Reference Figures 1 to 16This application also discloses a humidification therapy device, which includes a main unit, a humidification component 7, an electrical connector, and an electrical adapter 8. The main unit has a housing 1. The electrical connector is located on the housing 1 and is selected from the above-mentioned electrical connectors. The electrical adapter 8 has an air inlet pipe and an air outlet pipe. The air inlet pipe has a first port connected to the air outlet 21 and a second port connected to the air inlet pipe of the humidification component 7. The first port has air inlet electrical terminals on both sides that are electrically connected to the electrical connection terminals 3. One end of the air outlet pipe is connected to the air outlet pipe of the humidification component 7, and the other end is used to connect to the heating pipe.

[0120] The main unit provides power, communicates with, or provides control and feedback signals to the externally connected humidification component 7 or heating pipeline assembly via electrical connection terminal 3.

[0121] Because the humidification therapy device in this application uses the aforementioned electrical connector, the electrical connection terminal 3 and the air outlet 21 can be replaced individually, reducing the maintenance cost of the humidification therapy device. It also reduces the requirements for the electrical connector manufacturing process, lowering the production difficulty and cost, thereby reducing the overall production cost of the humidification therapy device. Furthermore, when disassembling the electrical adapter 8, the stress point of the electrical connection terminal 3 is located at the mounting base 2, ensuring the connection stability between the electrical connection terminal 3 and the internal circuit board of the main unit, thus extending the service life of the humidification therapy device. In addition, this electrical connector simultaneously provides both ventilation and power, facilitating the positioning between the electrical connector and the electrical adapter 8, thus simplifying the installation and removal of the electrical adapter 8 and making it easier for users to operate.

[0122] This application does not specify the connection method between the mounting base 2 and the outer casing 1, and it can adopt any of the following embodiments:

[0123] Implementation Method 1, in this implementation method, refer to Figure 1 , Figure 2 , Figure 5 and Figure 9 The mounting base 2 is a concave seat body, and the edge of the seat body is integrally formed with the outer shell 1, which increases the connection stability between the mounting base 2 and the outer shell 1, thereby ensuring the stability of the electrical connection terminal 3 and the one-way valve 4; and reduces the number of parts required to assemble the humidification therapy equipment, thereby improving the production efficiency of the humidification therapy equipment.

[0124] Implementation Method Two: In this implementation method, refer to... Figure 11 and Figure 12The outer shell 1 forms an opening, and at least a portion of the mounting base 2 passes through the opening. The mounting base 2 is connected to the outer shell 1 by fasteners, which simplifies the structural design of the outer shell 1, making it easier to manufacture the outer shell 1 and thus improving the production efficiency of the outer shell 1. It also enables the individual replacement of the mounting base 2, thereby reducing the maintenance cost of the humidification therapy equipment and improving the user experience.

[0125] The better one is to refer to Figure 12 The mounting base 2 has multiple fixing arms 26 extending outward from its periphery. Fasteners are connected to the fixing arms 26 to fix the mounting base 2 to the housing 1.

[0126] This application does not specifically limit the structure of the fastener. Preferably, the fastener is a screw, so as to reduce the difficulty of fixing the mounting base 2, improve the assembly efficiency of the humidification therapy device, reduce the production cost of the humidification therapy device, and at the same time increase the connection stability between the mounting base 2 and the outer shell 1.

[0127] In other embodiments, the fastener may also be other structures capable of securing the mounting base 2, such as a snap-fit ​​pin.

[0128] In the above-described second embodiment, the method of fixing the seal 5 is not specifically limited. It can adopt the method of fixing the seal 5 in the electrical connector, or it can adopt the following fixing methods or combine them with the method of fixing the seal 5 in the electrical connector:

[0129] Reference Figure 11 The electrical connector also includes a seal 5, with a periphery forming an edge 55 located between the mounting base 2 and the housing 1. The seal 5 is fixed by the compression of the edge 55 by the mounting base 2 and the housing 1, thereby increasing the stability of the seal 5 and ensuring the sealing effect of the seal 5 on the air outlet 21 and the electrical connection terminal 3. This also reduces the difficulty of installing the seal 5, improving the assembly efficiency of the humidification therapy device. Furthermore, it increases the sealing between the seal 5 and the mounting base 2 to prevent water or dirt from entering the main unit through the gap between the mounting base 2 and the housing 1, thus further extending the service life of the humidification therapy device.

[0130] In a preferred embodiment, the electrical connector further includes a sealing element 5. The sealing element 5 has a first sealing port 51 corresponding to the air outlet 21 and a second sealing port 52 corresponding to the mounting port 22. The electrical connection terminal 3 is sequentially disposed in the mounting port 22 and the second sealing port 52. The sealing element 5 forms a sealing end face. The first sealing port 51 and the second sealing port 52 are both located in the area formed by the sealing end face. A seal is formed between the first port of the electrical adapter 8 and the first sealing port 51, thereby increasing the sealing performance of the connection between the electrical adapter and the air outlet 21 to ensure the gas delivery efficiency. The end of the electrical adapter 8 forms a seal with the sealing end face, thereby increasing the sealing performance between the electrical adapter 8 and the mounting base 2 to prevent water from flowing through the gap between the electrical adapter 8 and the mounting base 2 to the electrical connection terminal 3 and contacting the electrical connection terminal 3, thereby avoiding short circuits in the humidification therapy device and extending the service life of the humidification therapy device.
