Description

Technical Field

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

[0002] Humidifiers with heating functions can heat and humidify the air, effectively improving comfort. They are widely used in daily life, such as in ventilators, air conditioners, and air purifiers.

[0003] The water tank is an important component of a humidifier. After being heated by the heating plate on the humidifier base, the liquid inside evaporates, thus humidifying and warming the air. When the water tank is low, the user can disassemble it to replenish it.

[0004] When the humidifier is working continuously, the heating plate will cause the bottom plate of the water tank to be locally hot. Disassembling the water tank at this time can easily cause burns and other problems, resulting in a low safety factor. Summary of the Invention

[0005] The purpose of this application is to provide a humidification component and a ventilator that can solve the problem in the prior art where, when the humidifier is working continuously, the heating plate causes the bottom plate of the water tank to have a high local temperature, making it easy to cause burns when disassembling the water tank and resulting in a low safety factor.

[0006] To solve the above-mentioned technical problems, this application is implemented as follows:

[0007] In a first aspect, embodiments of this application propose a humidification assembly, including: a base and a water tank;

[0008] The water tank is detachably connected to the base;

[0009] The base is provided with a heating plate, and the water tank has a heating surface that is opposite to the surface of the heating plate;

[0010] A medium layer is provided between the heating plate and the heated surface;

[0011] At a first temperature, the medium layer is in a non-stick state, so that the water tank and the base are detachable;

[0012] At the second temperature, the medium layer is in a viscous state, so that the water tank and the base are relatively fixed.

[0013] The first temperature is different from the second temperature.

[0014] Optionally, the first temperature is lower than the second temperature.

[0015] Optionally, the dielectric layer is coated on the surface of the heating plate or the heated surface.

[0016] Optionally, the heating surface of the water tank is provided with a heat-conducting plate, the heat-conducting plate is fixedly connected to the heating surface of the water tank, and the heat-conducting plate is arranged opposite to the heating plate;

[0018] Optionally, the dielectric layer is coated on the heating plate or the heat-conducting plate.

[0019] Optionally, the humidification assembly further includes: a carrier plate disposed between the heating plate and the heat-conducting plate;

[0020] The carrier plate has a first end face and a second end face that are disposed opposite to each other;

[0021] The heating plate or the heat-conducting plate is fixedly connected to the first end face, and the dielectric layer is coated on the second end face.

[0027] The base is connected to the main body of the ventilator.

[0028] In this embodiment, a medium layer is provided between the heating plate of the base and the heated surface of the water tank. At a first temperature, the medium layer is in a non-stick state, allowing relative movement between the heating plate and the heated surface of the water tank, thus enabling the water tank to be detached from the base. At a second temperature, the medium layer is in a viscous state, bonding the heating plate and the heated surface of the water tank together, thus fixing the water tank to the base. In practical use, when the local temperature of the water tank is excessively high, the viscous medium layer restricts the user's ability to disassemble the water tank, preventing scalding accidents and improving safety.

[0040] Reference Figures 1 to 4 The diagram shows a structural schematic of a humidification assembly according to an embodiment of this application. The humidification assembly includes: a base 20 and a water tank 30; the water tank 30 is detachably connected to the base 20; the base 20 is provided with a heating plate 201, and the water tank 30 has a heated surface opposite to the surface of the heating plate 201; a medium layer is provided between the heating plate 201 and the heated surface; at a first temperature, the medium layer is in a non-stick state, so that the water tank 30 is detachable from the base 20; at a second temperature, the medium layer is in a sticky state, so that the water tank 30 is relatively fixed to the base 20; wherein, the first temperature is different from the second temperature.

[0041] Specifically, such as Figures 1 to 4 As shown, the base 20 and water tank 30 are detachably connected, specifically by pulling or pressing. A heating plate 201 is provided on the side of the base 20 facing the water tank 30, and the base 20 supplies power to the heating plate 201. The water tank 30 has a receiving cavity for holding liquid. After the liquid in the receiving cavity is heated and evaporated, it humidifies and heats the gas. The humidification component can be applied to equipment such as ventilators, central air conditioners, and air purifiers to humidify and heat the gas passing through these devices. The humidification component can also be used independently for heating and humidifying indoor air.

[0042] The bottom of the water tank 30 has a heating surface that is opposite to the surface of the heating plate 201. The heating plate 201 heats the liquid inside the containment cavity through heat transfer. When the humidification component is working continuously, both the heating plate 201 and the heating surface at the bottom of the water tank 30 are at high temperatures. Disassembling the water tank 30 at this time can easily cause a scalding accident.

[0043] In this embodiment, a dielectric layer is provided between the heating plate 201 and the heated surface. The dielectric layer is connected to both the surface of the heating plate 201 and the heated surface, meaning it fills the gap between them. The dielectric layer has the following characteristics: At a first temperature, the dielectric layer is in a non-stick state, allowing relative movement between the heating plate 201 and the heated surface, and the disassembly of the base 20 and the water tank 30 is unrestricted. The first temperature differs from the second temperature; the first temperature can be a safe temperature that is unlikely to cause burns, while the second temperature can be a temperature that is likely to cause burns. At a second temperature, the dielectric layer is in a sticky state. Under the action of the dielectric layer, the heating plate 201 and the heated surface are bonded together and relatively fixed, thereby restricting the disassembly of the base 20 and the water tank 30.

[0044] In this embodiment, the first temperature is lower than the second temperature. For example, the first temperature is a temperature range below 75°C, specifically 25°C, 30°C, 35°C, 40°C, 50°C, 60°C, etc., which are temperatures unlikely to cause burns. The second temperature is a temperature range not lower than 75°C, such as 75°C, 80°C, 85°C, etc., which are temperatures likely to cause burns. The specific values ​​of the first and second temperatures correspond to the characteristics of the dielectric layer material.

[0045] In this embodiment, a medium layer is provided between the heating plate 201 of the base 20 and the heated surface of the water tank 30. At a first temperature, the medium layer is in a non-stick state, allowing relative movement between the heating plate 201 and the heated surface of the water tank 30, thus enabling the water tank 30 to be detached from the base 20. At a second temperature, the medium layer is in a sticky state, bonding the heating plate 201 and the heated surface of the water tank 30 together, thus fixing the water tank 30 to the base 20. In practical use, when the local temperature of the water tank 30 is excessively high, the sticky medium layer restricts the user's ability to disassemble the water tank 30, preventing scalding accidents and improving safety.

[0046] Optionally, the dielectric layer is coated on the surface of the heating plate 201 or the heated surface.

[0047] Specifically, the medium layer can be applied in the form of a coating to the surface of the heating plate 201 or the heated surface of the water tank 30. Preferably, the medium layer is applied to the surface of the heating plate 201. Since the surface of the heating plate 201 faces the bottom of the water tank 30, applying the medium layer to the surface of the heating plate 201 is less likely to cause peeling or falling off, thus improving the durability of the medium layer.

[0048] Optionally, refer to Figures 1 to 4 As shown, the heating surface of the water tank 30 is provided with a heat-conducting plate 301, which is fixedly connected to the heating surface of the water tank 30, and the heat-conducting plate 301 is arranged opposite to the heating plate 201; the medium layer is disposed between the heating plate 201 and the heat-conducting plate 301.

[0049] Specifically, such as Figures 1 to 4 As shown, the water tank 30 is typically made of materials such as PET (Polyethylene terephthalate) and ABS (Acrylonitrile Butadiene Styrene). To improve the uniformity of heating of the liquid inside the water tank 30 and to avoid the problem of harmful gases being generated from direct contact between the heating plate 201 and the water tank 30, a heat-conducting plate 301 is provided on the heated surface of the water tank 30. The heat-conducting plate 301 is made of a material with good thermal conductivity, such as metal. The heat-conducting plate 301 can be fixed to the heated surface of the water tank 30 by means of snap-fit, bonding, or integral molding.

[0050] A medium layer is disposed between the heating plate 201 and the heat-conducting plate 301. At the first temperature, the medium layer is in a non-stick state, and the heating plate 201 and the heat-conducting plate 301 can move relative to each other, and the disassembly of the base 20 and the water tank 30 is unrestricted. At the second temperature, the medium layer is in a sticky state. Under the action of the medium layer, the heating plate 201 and the heat-conducting plate 301 are bonded together and fixed relatively, thereby restricting the disassembly of the base 20 and the water tank 30.

[0051] Optionally, the dielectric layer is coated on the heating plate 201 or the heat-conducting plate 301.

[0052] Specifically, the medium layer can be coated onto the heating plate 201 or the heat-conducting plate 301 in the form of a coating. Preferably, the medium layer is coated onto the surface of the heating plate 201. Since the surface of the heating plate 201 faces the bottom of the water tank 30, the medium layer coated onto the surface of the heating plate 201 is less likely to peel off, thus improving the durability of the medium layer.

[0053] Optionally, refer to Figures 1 to 4 As shown, the humidification assembly also includes: a carrier plate 40, which is disposed between the heating plate 201 and the heat-conducting plate 301; the carrier plate 40 has a first end face and a second end face disposed opposite to each other; the heating plate 201 or the heat-conducting plate 301 is fixedly connected to the first end face, and the medium layer is coated on the second end face.

[0054] Specifically, such as Figures 1 to 4 As shown, to facilitate the coating of the dielectric layer, a carrier plate 40 can be placed between the heating plate 201 and the heat-conducting plate 301. The carrier plate 40 is preferably made of a material with good thermal conductivity to avoid affecting the heat transfer between the heating plate 201 and the heat-conducting plate 301. The thickness of the carrier plate 40 can be selected according to the size of the gap between the heating plate 201 and the heat-conducting plate 301.

[0055] The carrier plate 40 has a first end face and a second end face that are disposed opposite to each other, and the carrier plate 40 has the following two assembly methods:

[0056] Firstly, the first end face of the carrier plate 40 is fixedly connected to the heating plate 201. The specific connection method can be welding, snap-fitting, etc. The second end face of the carrier plate 40 is coated with a medium layer. Both the second end face and the medium layer face the heat conduction plate 301. The heat generated by the heating plate 201 is transferred to the heat conduction plate 301 through the carrier plate 40 and the medium layer, and then to the water tank 30. Under the heating of the heating plate 201, the temperature of the medium layer rises to the second temperature. At this time, the medium layer is in a viscous state, which can bond the carrier plate 40 and the heat conduction plate 301 together. Since the carrier plate 40 is fixedly connected to the heating plate 201, the heating plate 201 and the heat conduction plate 301 are relatively fixed, which restricts the disassembly of the base 20 and the water tank 30.

[0057] Secondly, the first end face of the carrier plate 40 is fixedly connected to the heat-conducting plate 301. The specific connection method can be welding, snap-fit, etc. The second end face of the carrier plate 40 is coated with a medium layer. Both the second end face and the medium layer face the heating plate 201. The heat generated by the heating plate 201 is transferred to the heat-conducting plate 301 through the carrier plate 40 and the medium layer, and then to the water tank 30. Under the heating of the heating plate 201, the temperature of the medium layer rises to the second temperature. At this time, the medium layer is in a viscous state and can bond the carrier plate 40 and the heating plate 201 together. Since the carrier plate 40 is fixedly connected to the heat-conducting plate 301, the heating plate 201 and the heat-conducting plate 301 are relatively fixed, which restricts the disassembly of the heating plate 201 and the water tank 30.

[0058] Optionally, along the direction perpendicular to the surface of the heating plate 201 or the heated surface, the projected area of ​​the medium layer is not less than half of the surface area of ​​the heating plate 201 or the heated surface area.

[0059] Specifically, in this embodiment, the viscous state of the medium layer at high temperatures is utilized to restrict the disassembly of the base 20 and the water tank 30. To ensure the restriction effect, there needs to be sufficient contact area between the medium layer and the surface or heated surface of the heating plate 201. Specifically, along the direction perpendicular to the surface or heated surface of the heating plate 201, the projected area of ​​the medium layer is not less than half of the surface area or heated surface area of ​​the heating plate 201. This ensures the stability of the bonding between the medium layer and the surface or heated surface of the heating plate 201, avoids insufficient adhesion due to insufficient contact area, and further improves the safety factor of the humidification component.

[0060] Optionally, the thickness of the dielectric layer is 0.1 mm to 1 mm.

[0061] Specifically, the thickness of the dielectric layer is 0.1mm-1mm, and can be 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.8mm, etc. The thickness of the dielectric layer should not be too thick, otherwise it will affect the heating efficiency of the heating plate 201; the thickness of the dielectric layer should also not be too thin, otherwise insufficient adhesion will occur. In the embodiments of this application, the thickness of the dielectric layer is preferably 0.3mm-0.5mm.

[0062] Optionally, refer to Figures 1 to 4 As shown, the outer wall of the water tank 30 is provided with an easy-pull section 50, which is used to provide a gripping space.

[0063] Specifically, such as Figures 1 to 4 As shown, to improve ease of use when the user disassembles the water tank 30, a pull part 50 is provided on the outer wall of the water tank 30. The pull part 50 provides a gripping space for the user. Specifically, the pull part 50 can be a groove structure formed on the outer wall of the water tank 30. When in use, the user can put their hand into the groove to apply force to the water tank 30 and disassemble it smoothly. The pull part 50 can also be a handle extending from the outer wall of the water tank 30, which the user can hold to disassemble the water tank 30 smoothly.

[0064] The pull section 50 and the water tank 30 can be manufactured separately and then assembled together by means of bonding, bolting, etc.; the pull section 50 and the water tank 30 can also be manufactured by integral molding, which improves structural stability and aesthetics.

[0065] Optionally, refer to Figures 1 to 4 As shown, the pull section 50 is provided with at least one anti-slip rib 60.

[0066] Specifically, such as Figures 1 to 4 As shown, to improve the stability of the water tank 30 when the user holds it and to prevent slippage, anti-slip ribs 60 are provided on the pull part 50. The anti-slip ribs 60 protrude from the surface of the pull part 50. The anti-slip ribs 60 and the pull part 50 can be manufactured separately or integrally molded. The specific number of anti-slip ribs 60 can be selected according to the size of the pull part 50, and this embodiment does not limit this.

[0067] Reference Figures 1 to 4 As shown in the figure, this application embodiment also provides a ventilator 10, including: a ventilator body 70 and the above-mentioned humidification component; a base 20 is connected to the ventilator body 70.

[0068] Specifically, such as Figures 1 to 4As shown, the ventilator body 70 houses components such as a control module, tubing, a fan, and a humidification assembly. The ventilator body 70 also includes a chamber for housing the water tank 30. The base 20 is typically located at the bottom of this chamber, and the ventilator body 70 supplies power to the heating plate 201 on the base 20. The base 20 and the ventilator body 70 can be manufactured as a single piece, or they can be manufactured separately and assembled using snap-fits, bolts, or other methods. The water tank 30 has a receiving cavity for holding liquid. A gas channel connecting the receiving cavity to the fan and the ventilator 10's outlet is located at the top of the receiving cavity. When the fan continuously generates pressurized gas, the gas enters the receiving cavity through the gas channel. After humidification and heating, the gas is transmitted through the gas channel to the ventilator 10's outlet. The ventilator 10's outlet then uses a ventilation tube and a breathing mask to deliver the humidified and heated gas to the patient.

[0069] In this embodiment, the base 20 is connected to the ventilator body 70. By providing a medium layer between the heating plate 201 of the base 20 and the heated surface of the water tank 30, the medium layer is in a non-stick state at low temperatures, allowing the heating plate 201 and the heated surface of the water tank 30 to move relative to each other, so that the water tank 30 and the base 20 are in a detachable state. At high temperatures, the medium layer is in a sticky state, which can bond the heating plate 201 and the heated surface of the water tank 30 together, so that the water tank 30 and the base 20 are relatively fixed. This restricts the user from disassembling the water tank 30 when the local temperature is too high, avoiding burns and improving the safety factor of the ventilator 10.
