[0026] The following is a clear and complete description of the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, not all of the embodiments, which does not constitute a limitation of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0027] First, the terms that may be used in this article are explained as follows:

[0028] The term “and / or” means that either or both of them can be realized at the same time. For example, X and / or Y means both “X” or “Y” and “X and Y”.

[0029] The terms "include", "comprises", "contains", "has" or other descriptions with similar semantics should be interpreted as non-exclusive inclusion. For example, including certain technical feature elements (such as raw materials, components, ingredients, carriers, dosage forms, materials, dimensions, parts, components, mechanisms, devices, steps, procedures, methods, reaction conditions, processing conditions, parameters, algorithms, signals, data, products or products, etc.) should be interpreted as including not only certain technical feature elements explicitly listed, but also other technical feature elements known in the art that are not explicitly listed.

[0030] The term "consisting of..." means excluding any technical feature elements not explicitly listed. If this term is used in a claim, it will make the claim closed, so that it does not contain technical feature elements other than the technical feature elements explicitly listed, except for the conventional impurities related to them. If this term only appears in a clause of a claim, it only limits the elements explicitly listed in the clause, and the elements recorded in other clauses are not excluded from the overall claim.

[0031] The contents not described in detail in the examples of the present utility model belong to the prior art known to professionals in the field. If no specific conditions are specified in the examples of the present utility model, the conditions are carried out according to the conventional conditions in the field or the conditions recommended by the manufacturer. If the manufacturers of the reagents or instruments used in the examples of the present utility model are not specified, they are all conventional products that can be purchased commercially.

[0032] The humidifier structure of the utility model comprises an upper shell 1 and a lower shell 4. One end of the upper shell 1 and the lower shell 4 are hinged by a cover opening shaft 9, and the other end is locked by a cover opening buckle 5. The cavity surrounded by the upper shell 1 and the lower shell 4 is a water storage cavity, and a seal is provided on the joint surface thereof. An evaporation disk 11 is provided at the bottom of the water storage cavity.

[0033] An air outlet 2 and an air inlet 3 are provided on one side of the upper shell 1, and a decorative plate 6 is provided on the other side. The decorative plate 6 completely covers the upper shell 1 and the lower shell 4 on this side and is provided with an assembly buckle 7;

[0034] The air inlet 3 is connected to the fan outlet, the air outlet 2 is connected to the breathing pipe, and a seal is provided at the connection part;

[0035] The inner surface of the upper shell 1 is provided with a water baffle 12, the cavity between the water baffle 12 and the air inlet 3 is an air inlet isolation cavity 15, and an air outlet water retaining structure is provided between the water baffle 12 and the air outlet 2, and the gas flow path is:

[0036] Air inlet 3 → air inlet isolation chamber 15 → water baffle 12 → water storage chamber → water baffle 12 → air outlet water baffle structure → air outlet 2.

[0037] The humidifier structure of the utility model is characterized in that the structure of the water baffle 12 is:

[0038] The structure near the air inlet 3 includes a B surface 17 and an A surface 16. The B surface 17 faces upward and surrounds the upper shell 1 to form an air inlet isolation chamber 15. The B surface 17 has an opening. The airflow from the air inlet 3 flows through the opening to the A surface 16 and changes the airflow direction before entering the humidifier water storage chamber.

[0039] The structure close to the air outlet 2 is a circular ring concentric with the air outlet 2, which together with the air outlet water retaining step 14 on the inner side of the air outlet constitutes the air outlet water retaining structure.

[0040] The cover opening shaft 9 is provided with a limiting structure, and the maximum opening angle is 100°.

[0041] An assembly guide angle 13 is provided at one end of the humidifier.

[0042] The decorative plate 6 is provided with a communicating vessel 8 communicating with the water storage chamber in the lower shell 4 . The communicating vessel 8 is a long transparent structure and is marked with a maximum water level line and a minimum water level line.

[0043] In summary, it can be seen that the humidifier structure of the embodiment of the utility model, as a part of the ventilator, has the functions of storing water and heating and humidifying the gas flowing through. It can store water and humidify and heat the gas, and at the same time, it has the characteristics of preventing water backflow and ensuring that no liquid will be sprayed or overflowed from the humidifier outlet under the conditions of large-flow gas delivery.

[0044] The principle is:

[0045] The gas enters from the air inlet, passes through the air inlet isolation chamber (to prevent backflow and change the gas flow direction), enters the water storage chamber to take away the water vapor (heating and humidification), and then passes through the air outlet water retaining structure and flows out from the air outlet.

[0046] The direction of the air flow from the air inlet isolation chamber into the water storage chamber is far away from the air outlet, ensuring that the gas is fully humidified in the water storage chamber and preventing the gas from flowing out of the air outlet before being fully mixed with the water vapor in the water storage chamber.

[0047] In order to more clearly demonstrate the technical solution and technical effects provided by the present invention, the embodiments of the present invention are described in detail with specific embodiments below.

[0048] Example 1

[0049] like Figure 1a , Figure 1b , Figure 2 , Figure 3 As shown:

[0050] A humidifier for a ventilator, mainly including an upper shell, a lower shell, a seal and an evaporation plate buckle, etc. The appearance of the whole machine is integrated and beautiful. A rotating shaft is provided at the rear and a cover opening buckle is provided at the front. Clamp the upper and lower shells. The rotating shaft is provided with a limit structure, and the maximum opening angle is 100°

[0051] A seal is provided between the upper and lower shells to prevent the humidifier from leaking water or air.

[0052] A large evaporation plate is provided at the bottom of the humidifier, which is welded to the lower shell and has a pre-buried sealing ring, so it has efficient evaporation and humidification effect and reliable sealing performance.

[0053] A long hole is opened on the decorative surface at the right end, and a connecting vessel is installed to facilitate water level observation, and the maximum water level line and the minimum water level line are marked.

[0054] The air inlet and the air outlet of the humidifier are respectively connected to the fan air outlet and the breathing pipeline of the ventilator through seals.

[0055] The right end of the humidifier is equipped with a guide angle, which is easy to assemble. The specific instructions are as follows:

[0056] Press the assembly buckle and take out the humidifier.

[0057] Open the upper shell and add water to the maximum water level;

[0058] Close the upper housing.

[0059] Put the humidifier back into the machine.

[0060] The working principle of the utility model is as follows Figure 3 As shown:

[0061] The air inlet of the humidifier is connected to the output port of the fan, and the air outlet of the humidifier is connected to the breathing tube.

[0062] Gas flow direction Figure 4a , Figure 4b , Figure 5 As shown:

[0063] Air inlet → air inlet isolation chamber → water storage chamber → air outlet water retaining structure → air outlet

[0064] The water retaining structure of the air outlet is as follows Figure 6a , Figure 6b , Figure 7 As shown:

[0065] The water baffle is welded to the upper shell, and the B surface and the upper shell form an isolation chamber. There are openings on the B surface, and the air flows through the openings and enters the humidifier water storage chamber. The A surface changes the direction of the air flow to prevent the air flow from blowing directly on the water surface. The water baffle has three functions:

[0066] Isolate the cavity and change the airflow direction to ensure that the air resistance will not be affected by the water level;

[0067] It has an anti-backflow function to prevent water from backflowing back into the fan when the humidifier is deflected to a certain angle;

[0068] It forms a water retaining structure with the outlet to prevent water from spraying out directly from the outlet when there is a large amount of airflow.

[0069] like Figure 8 , Figure 5 As shown:

[0070] Airflow details: After humidification, the airflow enters the air outlet from the F gap and the small hole on the edge of the E plate. When the airflow is large and the water level is high, water will splash. Both the E and F structures can block direct water splashing. The measured flow rate is 200L / M, and no water splashes;

[0071] Water retaining step: When the airflow is greater than 210L / min, tiny water droplets will condense on the top wall of the air outlet and slowly flow toward the air outlet. A water retaining step (3mm high) is provided on the top to effectively prevent water droplets from flowing out without increasing airway resistance.

[0072] The humidifier is equipped with an assembly buckle to facilitate assembly and clamp the humidifier and the host.

[0073] Buckles and connectors such as Fig. 9 , Fig.10 As shown, a connector is provided at the bottom to ensure that the right decorative surface is coordinated with the appearance of the main unit and facilitate water level observation.

[0074] The bottom of the humidifier is a large-area evaporation disk with excellent humidification effect.

[0075] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims. The information disclosed in the background technology section of this article is only intended to deepen the understanding of the overall background technology of the utility model, and should not be regarded as an admission or in any form that the information constitutes prior art known to those skilled in the art.
