Description

Technical Field

[0001] The utility model relates to a humidifier for a ventilator, belonging to the technical field of ventilators. Background Art

[0002] In order to improve the comfort of the ventilator, a humidifier is usually configured on the ventilator to increase the humidity of the gas inhaled into the human body. After the existing ventilator is started, it takes a long time to heat the water in the humidifier from room temperature to a suitable temperature (37±3°C), and it takes even longer in winter, bringing a bad experience to the treated person.

[0003] Prior art 1 (publication number CN219049984U) discloses a humidifier for a ventilator. A heat transfer component for connecting a heating element is installed at the lower end of the water tank body. The heat transfer component includes a heat conduction plate detachably connected to the lower end of the water tank body. The upper end of the heat conduction plate is provided with a receiving surface that can communicate with the liquid storage cavity and can hold the liquid. The lower end of the heat conduction plate is connected to the heating element; and a sealing member is provided between the heat conduction plate and the water tank body. The heating element includes a bracket erected on the bottom plate. An electric heating plate capable of abutting against the heat conduction plate body is provided on the bracket. A heat dissipation gap is provided between the electric heating plate and the bottom plate; the bracket includes a bracket ring plate. The lower end of the bracket ring plate is provided with a plurality of support legs that can abut against the bottom plate. A connection groove for embedding the electric heating plate is provided on the inner ring surface of the bracket ring plate.

[0004] The prior art 1 mainly has the following problems: 1. The covering area of the heat conduction plate only corresponds to the opening of the water tank body, and the area of the heat conduction plate is small, and the heat conduction efficiency needs to be improved; 2. The electric heating plate is rigidly abutted against the bottom of the heat conduction plate under the action of the support legs of the bracket. Due to the principle of thermal expansion and contraction, during long-term use, the electric heating plate continuously exerts an upward force on the heat conduction plate, resulting in upward deformation of the heat conduction plate, thereby causing a certain gap between the heat conduction plate and the electric heating plate, reducing the heat transfer efficiency from the electric heating plate to the heat conduction plate, and the temperature of the humidifier rising slowly, with poor user experience. Summary of the Utility Model

[0005] In order to overcome the problems existing in the prior art, the utility model provides a humidifier for a ventilator, which is beneficial to improving the heating efficiency of the humidifier of the ventilator. The specific technical solutions are as follows.

[0006] A humidifier for a ventilator, including a water tank and a heating component located at the bottom of the water tank, characterized in that:

[0007] The heating component includes a heat conducting plate and a heating element, and the heating element is located at the bottom of the heat conducting plate; the heat conducting plate is an integrally formed component and covers the entire bottom surface of the water tank; the heat conducting plate includes a connecting portion at the edge, and the connecting portion is fixed to the water tank.

[0008] With the above technical solution, compared with the prior art, the entire bottom of the water tank is a heat conducting plate, which can significantly improve the heat conduction effect and is beneficial to quickly increase the water temperature in the water tank.

[0009] Furthermore, the heating component further includes a bottom cover and a support frame. The support frame is fixed around the heating element, the bottom cover is fixed below the heat conducting plate, and the support frame and the heating element are both located in the space between the bottom cover and the heat conducting plate; an elastic component is arranged on the lower surface of the support frame, and the lower end of the elastic component abuts against the bottom cover, and the elastic component applies an upward force to the heating element so that the heating element abuts against the lower surface of the heat conducting plate. With such a setting, the elastic component can be used to adapt to the micro-deformation of each component caused by thermal expansion and contraction, so that the heating element always abuts against the heat conducting plate, thereby improving the heat transfer efficiency during the long-term use of the ventilator humidifier.

[0010] Furthermore, the elastic component is a soft pad distributed around the heating element. Those skilled in the art can understand that other forms of elastic components can also be used as long as they can provide elastic force for a long time without being affected by the heating element.

[0011] Furthermore, upwardly protruding ribs are arranged on the bottom cover. On the one hand, the ribs can prevent the heating element from coming into large-area contact with the bottom cover and avoid the heating element transferring too much heat to the bottom cover; on the other hand, the ribs can limit the downward movement distance of the heating element and prevent the heating element from accidentally moving downward too much and damaging the elastic component. Preferably, an avoidance groove is arranged in the middle of the rib. The arrangement of the avoidance groove is beneficial to accommodating the wires of the heating element and preventing the wires from interfering with the ribs.

[0012] Furthermore, the heat conducting plate further includes a groove portion, and the heating element is arranged corresponding to the groove portion. The water in the water tank corresponding to the groove portion can be quickly heated, which is beneficial to the rapid circulation of the water in the water tank.

[0013] Furthermore, the heat conducting plate is made of a metal material.

[0014] Furthermore, the connecting portion is fixed to the water tank by an adhesive bonding method. This fixing method not only simplifies the assembly process but also is beneficial to improving the waterproof performance and preventing the water in the water tank from leaking.

[0015] The utility model has the following beneficial effects compared with the prior art.

[0016] 1. The bottom of the water tank is an integral heat conduction plate, which is beneficial to improving the heating efficiency and waterproof performance of the humidifier.

[0017] 2. The heating component is attached to the heat conduction plate in an elastic abutting manner, so that the heating component can be reliably abutted against the heat conduction plate for a long time, avoiding excessive gaps between the heating component and the heat conduction plate due to long-term use.
