Description

Technical Field

[0001] This application relates to the field of ventilator technology, and in particular to a ventilator. Background Technology

[0002] A ventilator is a device that can replace, control, or alter a person's normal physiological breathing, increase lung ventilation, improve respiratory function, reduce respiratory strain, and conserve cardiac reserve. It is designed to reduce the irritation of the respiratory mucosa by cold, dry air.

[0003] In the relevant technical field, a ventilator includes a main unit and a water tank. A heat-conducting component is provided at the bottom of the water tank, and a heating component is provided on the main unit that is in contact with the heat-conducting component. The heat-conducting component is used to conduct heat from the heating component to the liquid in the water tank to humidify and heat the liquid.

[0004] However, if the heating element is placed directly on the main unit, the heat from the heating element will also be transferred to the turbine and internal cavity of the main unit, thus affecting the performance and lifespan of the ventilator. Utility Model Content

[0005] Therefore, it is necessary to provide a ventilator to address the problem of heat transfer from the heating component to the turbine and internal cavity of the main unit.

[0006] A ventilator, the ventilator comprising:

[0007] The host computer has a mounting slot on its housing;

[0008] A water tank is located on the main unit;

[0009] A heat-conducting component is installed on the water tank;

[0010] A heating component is disposed within the mounting groove and connected to the groove wall, the heating component being in contact with the heat-conducting element; and

[0011] A heat insulation component is disposed within the mounting groove, and the heat insulation component is disposed between the heating assembly and the main unit.

[0012] In one embodiment, a waterproof strip is also included, which is disposed on the outer peripheral surface of the thermal insulation member and extends circumferentially around the thermal insulation member.

[0013] In one embodiment, the heating assembly includes a heating sheet metal and a heating element connected together. The heating element is disposed between the heating sheet metal and the heat insulation member. The heating sheet metal is connected to the heat insulation member and can be attached to the heat-conducting member.

[0014] In one embodiment, the heated sheet metal is provided with a limiting groove on the side near the heat insulation member, and the limiting groove can be engaged with the waterproof strip.

[0015] In one embodiment, the heat insulation member has a receiving groove on the side near the heating component, the receiving groove being used to receive the components of the heating component.

[0016] In one embodiment, an elastic adjustment member is also included, which is connected to the insulation member and located between the insulation member and the heating assembly.

[0017] In one embodiment, the elastic adjustment member has a columnar structure, and multiple elastic adjustment members are provided, which are arranged circumferentially around the heat insulation member.

[0018] In one embodiment, the groove wall of the mounting groove and the end face of the heat insulation member facing away from the heating assembly are provided with a plug-in structure and a mating structure, and the plug-in structure and the mating structure are plugged in and mated.

[0019] In one embodiment, the mounting groove is provided with reinforcing ribs.

[0020] In one embodiment, the heating component has a first mounting channel on the side near the heat insulation component, and the heat insulation component has a second mounting channel on the side near the heating component. The locking component passes through the housing, the second mounting channel, and the first mounting channel in sequence, and is threadedly connected to the first mounting channel to connect the main unit, the heating component, and the heat insulation component.

[0021] The aforementioned ventilator incorporates a heat-conducting component on the water tank and a heating element on the main unit. When the ventilator is in operation, the heating element on the main unit is activated, and the heat-conducting component transfers heat to the liquid in the water tank, humidifying and heating the liquid. This, in turn, humidifies the air flowing from the ventilator, reducing the irritation of the respiratory mucosa caused by cold, dry air. Furthermore, by installing a heat insulation component between the heating element and the main unit, the heat transfer from the heating element to the turbine and internal cavity of the main unit is reduced, thereby improving the ventilator's performance and lifespan.

[0039] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0040] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms 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.

[0041] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0042] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," 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 or an electrical 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, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0043] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0044] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0045] This application provides a ventilator, such as Figures 1 to 7 As shown, the ventilator includes a main unit 200, a water tank 100, a heat-conducting component 300, a heating component 400, and a heat insulation component 500. The housing 210 of the main unit 200 is provided with a mounting groove 220; the water tank 100 is disposed on the main unit 200; the heat-conducting component 300 is disposed on the water tank 100; the heating component 400 is disposed in the mounting groove 220 and connected to the groove wall of the mounting groove 220, and the heating component 400 is in contact with the heat-conducting component 300; the heat insulation component 500 is disposed in the mounting groove 220 and is disposed between the heating component 400 and the main unit 200.

[0046] The aforementioned ventilator, by incorporating a heat-conducting component 300 on the water tank 100 and a heating component 400 on the main unit 200, allows the heating component 400 on the main unit 200 to be activated during operation. The heat-conducting component 300 transfers the heat from the heating component 400 to the liquid in the water tank 100, humidifying and heating the liquid. This, in turn, humidifies the air exiting the ventilator, reducing the irritation of the cold, dry air to the respiratory mucosa. Furthermore, by incorporating a heat insulation component 500 between the heating component 400 and the main unit 200, the heat insulation component 500 separates the heating component 400 from the main unit 200, reducing the heat transferred from the heating component 400 to the turbine and internal cavity of the main unit 200, thereby improving the performance and lifespan of the ventilator.

[0047] To improve the thermal conductivity of the heat-conducting component 300, such as Figure 1 and Figure 2 As shown, this application provides a through hole in the water tank 100. The heat-conducting component 300 includes a heat-conducting part and a connecting part arranged circumferentially around the heat-conducting part. The connecting part abuts against the inner wall of the water tank 100. The water tank 100 extends through the through hole and away from the water tank 100. That is, the heat-conducting part of the heat-conducting component 300 of this application passes through the through hole of the water tank 100 and is located on the outside of the water tank 100, which facilitates the heat-conducting component 300 to contact the heating assembly 400 for heat transfer.

[0048] Specifically, such as Figures 3 to 6As shown, the heating assembly 400 includes a heating sheet metal 410 and a heating element 420 connected together. The heating element 420 is disposed between the heating sheet metal 410 and the heat insulation member 500. The heating sheet metal 410 is connected to the heat insulation member 500 and can be attached to the heat-conducting member 300. The heating element 420 is disposed on the side of the heating sheet metal 410 near the heat insulation member 500, and the heat generated by the heating element 420 can be transferred to the heat-conducting member 300 through the heating sheet metal 410. Because the heat insulation member 500 is provided between the heating element 420 and the housing 210 of the main unit 200, heat transfer is isolated.

[0049] More specifically, in this embodiment, the heat insulation component 500 is a structural component made of rubber material. In other embodiments, the heat insulation component 500 can also be made of other materials, as long as the heat insulation effect can be achieved. For example, rock wool, glass wool, metal composite materials, etc. can also be used.

[0050] More specifically, such as Figures 3 to 6 As shown, the heating assembly 400 includes a temperature sensor and a safety protection element. The temperature sensor detects the heating temperature of the heating element 420 to determine whether the current heating temperature has reached the preset temperature. The safety protection element prevents the housing 210 of the main unit 200 from burning out due to excessive temperature of the heating element 420.

[0051] Specifically, such as Figures 3 to 6 As shown, a receiving groove 510 is provided on the side of the heat insulation member 500 near the heating assembly 400. The receiving groove 510 is used to receive the components of the heating assembly 400. By providing the receiving groove 510 on the heat insulation member 500, it is convenient to receive the components of the heating assembly 400. For example, temperature sensors and safety protection elements can be placed in the receiving groove 510.

[0052] It should be noted that, as Figures 3 to 6 As shown, the heat insulation component 500 is disposed in the mounting groove 220, that is, the receiving groove 510 disposed on the heat insulation component 500 is also disposed in the mounting groove 220.

[0053] More specifically, such as Figures 3 to 6 As shown, a wire hole 520 is provided in the receiving groove 510 to facilitate the passage of the cable of the heating component 400.

[0054] Specifically, such as Figures 3 to 6 As shown, it also includes a waterproof strip 700 connected end to end. The waterproof strip 700 is disposed on the outer peripheral surface of the heat insulation member 500 and extends circumferentially around the heat insulation member 500. By surrounding the outer peripheral surface of the heat insulation member 500 with the waterproof strip 700, a receiving space is formed between the waterproof strip 700 and the end face of the heat insulation member 500, preventing external liquids from flowing into the housing 210 of the main unit 200 through the heat insulation member 500.

[0055] More specifically, the waterproof strip 700 extends towards the side closer to the water tank 100 along the arrangement direction of the water tank 100 and the main unit 200.

[0056] More specifically, the heating sheet metal 410 is provided with a limiting groove on the side near the heat insulation component 500, and the limiting groove can be engaged with the waterproof strip 700. By providing the limiting groove, when the heating component 400 and the heat insulation component 500 are installed, the limiting groove and the waterproof strip 700 can be engaged, thereby reducing the mutual movement between the heat insulation component 500 and the heating component 400 and further improving the installation stability.

[0057] Furthermore, in order to improve the fit between the heating element 400 and the water tank 100, such as Figures 3 to 6 As shown, the ventilator also includes an elastic adjustment element 600, which is connected to the heat insulation element 500 and located between the heat insulation element 500 and the heating element 400. With the elastic adjustment element 600 positioned between the heating element 400 and the heat insulation element 500, when the heat-conducting element 300 of the water tank 100 and the heating element 400 are in contact, the weight of the water tank 100 causes the heat-conducting element 300 to press against the heating element 400 in a first direction. Since the elastic adjustment element 600 is made of elastic material, it undergoes elastic deformation under pressure. The degree of elastic deformation is greater in areas of higher pressure and less in areas of lower pressure. This elastic deformation adjusts the fit between the heat-conducting element 300 and the heat transfer element, increasing the contact area between them. The ventilator of this application reduces the heat transferred from the heating component 400 to the main unit 200 by providing a heat insulation component 500 between the heating component 400 and the main unit 200, and improves the heat transfer efficiency by providing an elastic adjustment component 600 between the heat insulation component 500 and the heating component 400.

[0058] Specifically, such as Figures 3 to 6 As shown, the elastic adjustment element 600 has a columnar structure, and multiple elastic adjustment elements 600 are arranged circumferentially around the heat insulation element 500. By providing multiple elastic adjustment elements 600, they can work together, thereby increasing the adjustment area and further improving the fit between the heating component 400 and the heat-conducting component 300.

[0059] More specifically, in this embodiment, the heat insulation component 500 and the elastic adjustment component 600 are integrally injection molded. In other embodiments, a connecting structure may be provided to connect the elastic adjustment component 600 and the heat insulation component 500.

[0060] Furthermore, to improve the installation stability of the heat insulation component 500 and the heating assembly 400 within the mounting groove 220, such as Figures 3 to 6As shown, the groove wall of the mounting groove 220 and the end face of the heat insulation component 500 facing away from the heating assembly 400 have a plug-in structure 800 and a mating structure, respectively. The plug-in structure 800 and the mating structure are plugged into each other. By providing the plug-in structure 800 and the mating structure, when the heat insulation component 500 is placed in the mounting groove 220, the plug-in structure 800 and the mating structure are plugged into each other, thereby reducing the shaking of the heat insulation component 500 in the mounting groove 220.

[0061] In this embodiment, a mating structure is provided on the wall of the mounting groove 220, and a plug-in structure 800 is provided on the end face of the heat insulation component 500 on the side away from the heating component 400.

[0062] Specifically, the plug-in structure 800 and the mating structure form a set of plug-in units. Multiple sets of plug-in units are arranged at intervals around the heat insulation component 500.

[0063] like Figures 3 to 6 As shown, a first mounting channel 411 is provided on the side of the heating component 400 near the heat insulation component 500, and a second mounting channel 530 is provided on the side of the heat insulation component 500 near the heating component 400. A locking member 900 passes sequentially through the housing 210, the second mounting channel 530, and the first mounting channel 411, and is threaded into the first mounting channel 411 to connect the main unit 200, the heating component 400, and the heat insulation component 500. By providing the first mounting channel 411 and the second mounting channel 530, and utilizing the locking member 900 passing through the housing 210, the second mounting channel 530, and the first mounting channel 411, the main unit 200, the heating component 400, and the heat insulation component 500 are connected, further enhancing the installation stability of the heat insulation component 500 and the heating component 400 within the mounting groove 220.

[0064] Specifically, a first mounting channel 411 is provided on the heating sheet metal 410 of the heating assembly 400.

[0065] Specifically, such as Figure 7 As shown, a reinforcing rib 230 is provided inside the mounting groove 220. By providing the reinforcing rib 230 inside the mounting groove 220, the structural strength of the mounting groove 220 is increased, which in turn increases the structural strength of the shell 210, thereby reducing the probability of the shell 210 shrinking and deforming due to heat.

[0066] Understandably, the shape of the reinforcing rib 230 is determined based on the actual operational needs.

[0067] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
