Description

Technical Field

[0001] This utility model relates to the field of ventilation therapy technology, specifically to a heating component, a humidifier including the heating component, and a ventilation therapy device including the humidifier. Background Technology

[0002] Ventilation therapy equipment, such as ventilators, has become a common device used for respiratory diseases. When using a ventilator, the air needs to be heated and humidified to provide patients with a better breathing experience. This process involves heating the liquid in the humidifier's reservoir, and the resulting water vapor humidifies the breathing air.

[0003] The common heating and humidification method of humidifiers is to set a heat-conducting plate at the bottom of the humidifier and a heating plate on the main unit. After the humidifier is connected to the main unit, the heat-conducting plate at the bottom of the humidifier contacts the heating plate, and the heat generated by the heating plate is conducted to the liquid inside the storage chamber through the heat-conducting plate.

[0004] However, during the heat transfer process between the heat conduction plate and the heating plate, complete contact between the contact surfaces cannot be achieved, resulting in heat loss during heat transfer. Furthermore, problems such as poor sealing, insufficient structural strength, and insufficient flatness at the connection between the heating plate and the humidifier can easily occur, affecting heat transfer. In addition, friction occurs during the disassembly and assembly of the humidifier and the main unit, causing scratches and damage to both the heat conduction plate and the heating plate.

[0007] This invention provides a heating component that can be installed within the shell wall of a humidifier's liquid storage chamber, avoiding direct contact with the liquid. This eliminates safety hazards caused by direct contact and prevents corrosion and accelerated aging from prolonged contact. Furthermore, because the heating component is integrated or detachably installed inside the shell, it avoids issues like poor contact or wear due to frequent contact, resulting in high heat utilization. The installation of the heating component within the shell does not affect the humidifier's internal volume or external dimensions. Additionally, the use of a wire circuit for heating not only facilitates heating control but also allows for the integration of various detection components to simultaneously monitor water temperature, water level, and air pressure within the humidifier.

[0056] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0057] The first aspect of this utility model provides a heating assembly, see [link to previous section]. Figure 1 and Figure 2The heating assembly 10 is disposed within the housing wall of the humidifier 20 that defines the liquid storage chamber 21. The heating assembly 10 includes an interconnected wire circuit 11 and an electrode 12. The electrode 12 is connected to an external power source (e.g., the main unit of a ventilation therapy device) to energize the wire circuit 11.

[0058] This invention, by adopting the above-described technical solution, provides a heating component 10 that can be installed within the housing wall of the humidifier 20, which defines the liquid storage chamber 21. The heating component 10 can heat the liquid without direct contact, thus avoiding safety hazards caused by direct contact and corrosion and accelerated aging due to prolonged contact. Furthermore, since the heating component is integrated or detachably installed inside the housing, there are no issues such as poor contact or wear caused by frequent contact between the heating component 10 and the humidifier 20, resulting in high heat utilization. It also does not affect the internal volume or external dimensions of the humidifier, facilitating device miniaturization. In addition, the heating component 10 uses a metal wire circuit 11 for heating, which not only facilitates heating control but also allows for the integration of various detection components to simultaneously monitor the water temperature, water level, and air pressure inside the humidifier. The above-mentioned technical solution of this utility model can optimize the structural size of the humidifier while effectively integrating various measurement requirements, eliminating additional auxiliary measurement components, and has manufacturability, usability, safety, and high efficiency. At the same time, it can effectively reduce installation and maintenance costs, and will not increase the gas resistance and pressure difference of the humidifier itself.

[0059] In this invention, electrode 12 can also be used to connect to an external controller (such as the main unit of a ventilation therapy device) to realize communication (i.e., signal transmission) of the wire circuit 11. In this way, when the wire circuit 11 integrates various detection components, the data detected by the detection components can also communicate with the external controller, which is beneficial for better control of the humidifier's heating and humidification.

[0060] In some embodiments of this invention, electrode 12 can be a dual-contact electrode, i.e., a set of contact electrodes. In this case, the metal wire circuit 11 can be a series circuit, with heating achieved through the dual-contact electrodes. In other embodiments, electrode 12 can be a multi-contact electrode, i.e., multiple sets of contact electrodes. In this case, the metal wire circuit 11 can include multiple sets of parallel circuits, with each pair of corresponding contact electrodes forming a set connected to a set of circuits. This allows for independent control of the heating area of ​​the metal wire circuit 11 and communication between the various detection components.

[0061] In this invention, electrode 12 can be configured to extend beyond the housing wall (see [reference]). Figure 1 and Figure 6In this case, the main unit of the ventilation therapy device has a socket for inserting electrode 12. Of course, electrode 12 may also not protrude from the housing wall (see...). Figure 2 and Figure 7 In this case, the main unit of the ventilation therapy device may have a protrusion for connection with electrode 12.

[0062] In this invention, the wire circuit 11 can be configured in a mesh shape, which facilitates its installation within one side wall of the humidifier's housing (e.g., the bottom housing wall). Alternatively, the wire circuit 11 can also include multiple planar mesh portions to adapt to different side walls of the humidifier's housing. For example... Figure 1 and Figure 2 As shown, the wire circuit 11 includes a bottom circuit portion 111 adapted to the bottom contour of the liquid storage cavity 21 and a side circuit portion 112 adapted to the circumferential contour of the liquid storage cavity 21.

[0063] To further improve the heating effect of the heating assembly 10, the heating assembly 10 may also include a heating resistance sheet 13 with a large heating area disposed on the wire circuit 11, for example, the heating resistance sheet 13 is embedded in the grid of the wire circuit 11. Increasing the flat area or thickness of the heating resistance sheet 13 can give it a larger heating area or higher heating power, thereby enabling efficient heating of the liquid storage chamber. It should be noted that there can be multiple heating resistance sheets 13. For example, heating resistance sheets 13 can be disposed in the bottom grid of the wire circuit 11, or in all (bottom and side) grids, or only in a portion of the bottom grid. The specific placement and number of heating resistance sheets 13 are determined according to the heating requirements. When the wire circuit 11 uses multiple parallel circuits, the heating resistance sheet 13 corresponding to each circuit can be controlled together with that circuit. The heating resistance sheet 13 can be a single-layer structure, and its heating power can be automatically adjusted according to the heating area, and can also be increased according to the thickness of the heating resistance sheet, which can be between 0.02mm and 10mm.

[0064] To further improve the humidification effect on the gas, the heating assembly 10 may also include an atomizing plate 14 disposed on the wire circuit 11. For example... Figure 1 or Figure 2 As shown, the atomizing plate 14 can be arranged parallel above the grid of the wire circuit 11 so that it can extend into the liquid storage chamber and directly contact the liquid while being connected to the wire circuit 11.

[0065] In some embodiments, the heating assembly 10 may further include a liquid level sensor 15, which is used to detect the liquid level in the liquid storage chamber 21. The number and location of the liquid level sensors 15 are not limited. Specifically, as shown... Figure 1 or Figure 2In the illustrated embodiment, the heating assembly 10 may include a plurality of (e.g., three) liquid level sensors 15, which are spaced apart along the height direction of the liquid storage chamber 21 on the side circuit portion 112 of the wire circuit 11, thereby enabling the detection of liquid levels at different heights in the liquid storage chamber 21. This arrangement allows for the implementation of limit warnings for the liquid level within the humidifier.

[0066] In some embodiments, the heating assembly 10 may further include a temperature sensor 16 for detecting the temperature within the liquid storage chamber 21. The number and location of the temperature sensors 16 are not limited. Specifically, as shown... Figure 1 or Figure 2 In the illustrated embodiment, the heating assembly 10 may include a plurality of (e.g., three) temperature sensors 16, which are spaced apart along the height direction of the liquid storage chamber 21 on the side circuit portion 112 of the wire circuit 11, thereby enabling the detection of temperature at different height positions within the liquid storage chamber 21. This arrangement allows for the detection of the temperature of the liquid and water vapor within the humidifier.

[0067] In some embodiments, the heating assembly 10 may further include a pressure sensor 17 for detecting the air pressure within the liquid storage chamber 21. The number and location of the pressure sensors 17 are not limited. Specifically, as shown... Figure 1 or Figure 2 In the embodiment shown, the heating assembly 10 may include a plurality of (e.g., three) pressure sensors 17, which are spaced apart on the side circuit portion 112 of the wire circuit 11 along the height direction of the liquid storage chamber, thereby enabling the detection of pressure at different height positions within the liquid storage chamber 21.

[0068] It should be noted that the liquid level sensor 15, temperature sensor 16, and pressure sensor 17 described above are all non-contact sensors, meaning they do not directly contact the liquid or gas in the storage chamber 21. This avoids corrosion or damage to the sensors caused by the liquid or gas in the storage chamber 21. For example, the liquid level sensor 15 can be a capacitive sensor, and the pressure sensor 17 can be a piezoelectric sensor. Since these sensors are all existing technologies, they will not be described in detail here. The above sensors can communicate via wired or wireless means.

[0069] In some embodiments, the heating assembly 10 may further include an LED element 18 connected to the wire circuit 11 for illuminating the liquid storage chamber 21. This allows for observation of the interior of the liquid storage chamber. Specifically, as shown... Figure 1 or Figure 2As shown, the LED element 18 is connected to the side circuit portion 112 of the wire circuit 11 and is formed into a long strip extending along the height direction of the liquid storage cavity. This allows for accurate and rapid observation of the liquid level in the humidifier under illumination. For easier observation, an observation port can also be provided on the corresponding housing wall for the LED element 18.

[0070] The second aspect of this utility model provides a humidifier, see [link to relevant documentation] Figures 3-11 The humidifier 20 includes a housing for defining a liquid storage chamber 21, and a heating component 10 for heating the liquid storage chamber 21 is disposed inside the housing wall.

[0071] By adopting the above-described technical solution, this utility model places the heating component 10 within the housing wall of the humidifier 20, which defines the liquid storage chamber 21. The heating component 10 can heat the liquid without direct contact with it, avoiding problems such as poor contact or wear caused by frequent contact. This results in high heat utilization and does not affect the internal volume or external dimensions of the humidifier, facilitating device miniaturization. Furthermore, the heating component 10 uses a metal wire circuit 11 for heating, which not only facilitates heating control but also allows for the integration of various detection components to simultaneously monitor water temperature, water level, and air pressure within the humidifier. This utility model's technical solution optimizes the humidifier's structural dimensions while effectively integrating various measurement requirements, eliminating the need for additional auxiliary measurement components. It offers manufacturability, usability, safety, and high efficiency, while effectively reducing installation and maintenance costs without increasing the humidifier's gas resistance or pressure difference.

[0072] In this invention, the housing of the humidifier 20 can be either one-piece or two-piece. The housing wall of the humidifier 20, which houses the heating element 10, can be a two-layer or three-layer structure.

[0073] For example Figures 3-11 In the illustrated embodiment, the housing is a split type, including an upper housing 22 and a lower housing 23. The liquid storage chamber 21 may be defined by both the upper housing 22 and the lower housing 23, or it may be defined only by the lower housing 23. For ease of installation of the heating assembly 10, the liquid storage chamber 21 is preferably defined by the lower housing 23.

[0074] The lower housing 23 can be a single-wall structure. In this case, the heating component 10 can be molded inside the lower housing 23 during the molding process (forming a two-layer structure as described above, consisting of the heating component and the single-wall structure). The lower housing 23 can also be a multi-wall structure. In this case, the lower housing 23 may include a nested outer shell 231 and an inner shell 232, with the heating component 10 sandwiched between the outer shell 231 and the inner shell 232 (forming a three-layer structure as described above, consisting of the inner shell, the heating component, and the outer shell). During manufacturing, the heating component 10 can be injection molded together with the inner shell 232 first, and then injection molded together with the outer shell 231. Figure 8 As shown, a groove 2321 for embedding the heating component 10 can also be formed on the outer surface of the inner shell 232 to achieve a stable installation of the heating component 10. The shape of the groove 2321 is adapted to the shape of the heating component 10.

[0075] like Figure 6 and Figure 7 As shown, the outer casing 231 may also have an opening 2311 for the electrode 12 to extend out of the opening 2311 (see [reference]). Figure 6 It can also extend into opening 2311 (see...) Figure 7 ).

[0076] The heating element 10 preferably covers the entire bottom and at least a portion of the side of the liquid storage chamber 21 to achieve uniform and efficient heating of the liquid within the chamber. It should be noted that the heating function of the side portion of the heating element is preferably coordinated with a liquid level sensor or temperature sensors at different heights to prevent the circuitry at the higher parts of the humidifier's sidewall from continuing to operate when the liquid level in the humidifier is low, thus avoiding dry heating at the higher parts of the humidifier and potential safety hazards. Specifically, for example, when the liquid level in the humidifier is low, the circuitry at the lower part of the humidifier's sidewall will generate significant heat.

[0077] In this invention, the outer shell 231 and the inner shell 232 can be made of different materials. For example, the outer shell 231 can be made of soft rubber (e.g., silicone), which can provide heat insulation; the inner shell 232 can be made of hard rubber (e.g., plastic), which can better conduct the heat generated by the heating component to the liquid storage chamber.

[0078] The inner shell 232 can be made transparent, allowing for easy observation of the liquid level, water temperature, and color within the storage chamber through illumination from the LED elements in the heating assembly. Furthermore, a light guide strip 2322 can be protruding from the outer surface of the inner shell 232, and an observation port 2312 is provided on the outer shell 231 corresponding to the light guide strip 2322. Observing the light guide strip 2322 through the observation port 2312 allows for better observation of the internal conditions of the storage chamber.

[0079] In this utility model, such as Figure 8 As shown, both the outer shell 231 and the inner shell 232 can be box-shaped with an open top. In this case, the lower shell 23 may also include a top cover 233, which covers the outer shell 231 and the inner shell 232. The top cover 233 may have an inlet 2331 communicating with the liquid storage chamber 21. Preferably, the opening area of ​​the inlet 2331 is greater than half of the circumferential contour area of ​​the top cover 233, which facilitates the efficient addition of water to the liquid storage chamber and the discharge of humidifying gas.

[0080] The top cover 233 has a protruding annular boss 2332 that surrounds the water inlet 2331. The alignment and cooperation between the annular boss 2332 and the internal structure of the upper housing 22 facilitates better installation of the lower housing 23 with the upper housing 22. Furthermore, the protruding annular boss 2332 around the upper surface of the top cover 233 increases the overall height of the lower housing 23, effectively preventing liquid overflow from the lower housing 23.

[0081] In this utility model, such as Figure 10 and Figure 11 As shown, when the heating assembly has an atomizing plate 14, the bottom of the inner shell 232 may have an installation port 2323 for sealing installation of the atomizing plate 14. The atomizing plate 14 extends into the liquid storage chamber 21 to directly heat, humidify, and atomize the water in the liquid storage chamber, and can assist in increasing the humidification capacity according to the heating and humidification situation, providing users with a better user experience.

[0082] This invention improves the humidifier structure by adding a heating component (i.e., a heating integrated circuit) to the humidifier's casing. This heating component heats and humidifies the humidifier and can activate one or more circuits and heating resistors according to heating and humidification requirements, achieving real-time automatic adjustment. This effectively solves the problems existing in current humidifier heating methods.

[0083] The third aspect of this utility model provides a ventilation therapy device, including a main unit and a humidifier 20. The electrodes 12 of the humidifier 20 are connected to the main unit, thereby enabling power supply. Preferably, it can also enable communication.

Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.

Those skilled in the art should understand that modifications can be made to the above embodiments or equivalent substitutions can be made to some technical features without departing from the scope and spirit of the present invention.
