[0041] The following further elaborates on the content of the present invention in conjunction with specific embodiments:

[0042] Embodiment 1

[0043] As Figures 1-4 shown, a novel humidifying canister structure includes a housing 1, a liquid storage cavity 2, a liquid inlet cavity 3, an air inlet cavity 4, and an air outlet cavity 5 formed within the housing 1, an air inlet pipeline 6 communicating with the air inlet cavity 4, and an air outlet pipeline 7 communicating with the air outlet cavity 5.

[0044] As Figure 3 , Figure 4 shown, the housing 1 includes a left shell 11 and a right shell 12 distributed horizontally. The left shell 11 and the right shell 12 are connected by a snap - fit method, and a sealing silicone 13 is provided therebetween. The liquid storage cavity 2 is arranged within the left shell 11, and the liquid inlet cavity 3, the air inlet cavity 4, and the air outlet cavity 5 are arranged within the right shell 12.

[0045] Combined with Figure 5As shown, the intake cavity 4 and the outlet cavity 5 are separated by a partition plate 121. A flow guide plate 122 is connected below the partition plate 121. The liquid inlet cavity 3 is formed below the flow guide plate 122. The liquid inlet cavity 3 is communicated with the intake cavity 4 through a first air hole 123 provided on the flow guide plate 122, and is communicated with the outlet cavity 5 through a second air hole 124 provided on the flow guide plate 122. Both the first air hole 123 and the second air hole 124 are arranged away from the partition plate 121, which is used to increase the travel of the air flow in the liquid inlet cavity 3, so that the gas is fully mixed with the liquid heated and vaporized in the liquid inlet cavity 3.

[0046] As Figure 3 , Figure 4 shown, the intake pipeline 6 flows through the left housing 11, the sealing silica gel 13 and the right housing 12 in sequence, that is, Figure 3 the path shown by the dotted line in the intake direction in, including an intake port 61 formed on the left housing 11, a first pipe body 62, an intake sealing hole 63 formed on the sealing silica gel 13, and a second pipe body 64 formed on the right housing 12. Both the first pipe body 62 and the second pipe body 64 are inserted into the intake sealing hole 63, and the second pipe body 64 has a first notch 65 communicated with the intake cavity 4.

[0047] As Figure 3 , Figure 4 shown, the outlet pipeline 7 flows through the right housing 12, the sealing silica gel 13 and the left housing 11 in sequence, that is, Figure 3 the path shown by the dotted line in the outlet direction in, including a third pipe body 71 formed on the right housing 12, an outlet sealing hole 72 formed on the sealing silica gel 13, and a fourth pipe body 73 and an outlet port 74 formed on the left housing 11. Both the third pipe body 71 and the fourth pipe body 73 are inserted into the outlet sealing hole 72, and the third pipe body 71 has a second notch 75 communicated with the outlet cavity 5.

[0048] Furthermore, after the gas flows in from the intake pipeline 6, it flows according to Figure 5 the direction of the dotted arrow shown, and flows out from the outlet pipeline 7. The flow path is: intake port 61 - first pipe body 62 - intake sealing hole 63 - second pipe body 64 - first notch 65 - intake cavity 4 - first air hole 123 - liquid inlet cavity 3 - second air hole 124 - outlet cavity 5 - second notch 75 - third pipe body 71 - outlet sealing hole 72 - fourth pipe body 73 - outlet port 74.

[0049] Combined with Figure 3 , Figure 4 , Figure 6As shown in the figure, there is a metal chassis 111 for heat transfer below the liquid storage chamber 2. The liquid storage chamber 2 is communicated with the liquid inlet chamber 3 through the water inlet hole A131 at the lower end. The water inlet hole A131 penetrates through the sealing silica gel 13. After the liquid storage chamber 2 is filled with liquid in the water inlet hole A131, it is isolated from the outside atmosphere. Under normal conditions, there is a high-level liquid in the liquid storage chamber 2 and a low-level liquid in the liquid inlet chamber 3. The principle of their connection is as follows:

[0050] First, load the liquid into the liquid storage chamber 2. After the liquid loading is completed, place the structure as Figure 5 shown in the figure. At this time, the liquid in the liquid storage chamber 2 is at a high level, and the potential energy causes the liquid to flow into the liquid inlet chamber 3 through the water inlet hole A131. When the water level in the liquid inlet chamber 3 rises and covers the water inlet hole A131, the liquid filled in the water inlet hole A131 plays an isolation role, isolating the liquid storage chamber 2 from the outside atmosphere. A negative pressure will be generated above the liquid surface in the liquid storage chamber 2 and gradually balance the potential energy of the water. Finally, the water level in the liquid inlet chamber 3 will no longer rise. When the water in the liquid inlet chamber 3 gradually vaporizes and is carried away by the air flow, the liquid level drops, and the water in the liquid storage chamber 2 will replenish the liquid inlet chamber 3 through the water inlet hole A131.

[0051] In this embodiment, the humidifying tank is used in cooperation with the machine body. Therefore, it adopts a left-right distribution method. The left shell 11 is installed inside the machine body, and the right shell 12 is the direct appearance surface, retaining the integrity of the appearance to the greatest extent. Due to the installation method, it is impossible to directly know the liquid level of the liquid storage chamber 2. Therefore, as a further optimization, as Figure 5 shown in the figure, an independent liquid level chamber 8 is also provided in the right shell 12. The liquid level chamber 8 is communicated with the liquid storage chamber 2 through the water inlet hole B132 and the ventilation hole 133. Both the water inlet hole B132 and the ventilation hole 133 are provided on the sealing silica gel 13. The liquid in the liquid storage chamber 2 can directly enter the liquid level chamber 8 through the water inlet hole B132. The ventilation hole 133 is used to balance the air pressure, so that the liquid levels in the liquid storage chamber 2 and the liquid level chamber 8 are the same. The outer wall of the right shell 12 opposite to the liquid level chamber 8 is transparent and has scales for displaying the liquid level.

[0052] The working steps in this embodiment are specifically as follows:

[0053] (1) Disassemble the buckled left shell 11 and right shell 12, and fill pure water or medicine liquid into the liquid storage chamber 2. After the filling is completed, buckle the sealing silica gel 13 and the right shell 12 onto the left shell 11 again;

[0054] (2) Assemble the structure with the machine body. The metal chassis 111 contacts the heating plate in the machine body to transfer heat to the pure water or medicine liquid in the water storage chamber;

[0055] (3) High-flow gas is introduced through the intake pipeline 6, rotates in the intake cavity 4 and then enters the liquid intake cavity 3. After being fully mixed with the liquid heated and vaporized in the liquid intake cavity 3, it enters the air outlet cavity 5 and is finally led out along the outlet pipeline 7.

[0056] In the description of this embodiment, it should be understood that the orientation or positional relationship indicated by the terms "left", "right", "upper", "lower", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the invention and simplifying the description, rather than indicating that the structure must have a specific orientation, be constructed and operated in a specific orientation, so it should not be construed as a limitation to the invention.

[0057] Embodiment 2

[0058] As Figures 7-12 shown, a new type of humidifying tank structure includes a housing 1, a liquid storage cavity 2, a liquid intake cavity 3, an air intake cavity 4 and an air outlet cavity 5 formed inside the housing 1, an intake pipeline 6 communicating with the air intake cavity 4, and an outlet pipeline 7 communicating with the air outlet cavity 5.

[0059] As Figure 8 、 Figure 12 shown, the housing 1 includes an upper shell 14 and a lower shell 15 distributed along the vertical direction, and internally forms a square-shaped cavity, including an inner ring cavity 17 and an outer ring cavity 18. Below the inner ring cavity 17 is the liquid intake cavity 3, and above it are the air intake cavity 4 and the air outlet cavity 5. The outer ring cavity 18 is the liquid storage cavity 2. In this embodiment, a metal chassis can be provided only below the outer ring cavity 18, or a metal chassis can be provided jointly below the outer ring cavity 18 and the inner ring cavity 17.

[0060] Specifically, the upper shell 14 includes an outer cover 141 and an inner cover 142 with both lower ends being open, and the upper end of the lower shell 15 is open. The outer cover 141 is buckled with the lower shell 15 and sealed with a sealant 16. The lower end of the inner cover 142 is in sealed cooperation with the inner bottom surface of the lower shell 15, and a baffle 143 is also provided inside along the vertical direction. The inner ring cavity 17 is formed inside the inner cover 142, the air intake cavity 4 and the air outlet cavity 5 are respectively arranged on both sides of the baffle 143, the outer ring cavity 18 is formed outside the inner cover 142, and a water inlet hole A131 is formed on the side wall of the lower end of the inner cover 142. After the water inlet hole A131 is filled with liquid, the outer ring cavity 18 / liquid storage cavity 2 is isolated from the outside atmosphere, and the principle of communication between the liquid storage cavity 2 and the liquid intake cavity 3 is the same as that in Embodiment 1.

[0061] During operation, high-flow gas is introduced into the air intake cavity 4 through the intake pipeline 6, descends in the air intake cavity 4 and enters the liquid intake cavity 3. After being fully mixed with the liquid heated and vaporized in the liquid intake cavity 3, it enters the air outlet cavity 5 and is finally led out along the outlet pipeline 7.

[0062] In the description of this embodiment, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "vertical", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the invention and simplifying the description, rather than indicating that the structure must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the invention.

[0063] Combining Embodiment 1 and Embodiment 2, the present invention combines the liquid storage cavity 2 with a high liquid level and the liquid inlet cavity 3 with a low liquid level. Only a small amount of liquid enters the liquid inlet cavity 3. Even if the housing 1 is overturned, inverted, or vibrated with a large amplitude at will, a large amount of liquid will not immediately flow out from the air inlet 61 and the air outlet 74. At the same time, the air inlet cavity 4 and the air outlet cavity 5 are only connected to the liquid inlet cavity 3 with a low liquid level, and the gas does not communicate with the liquid storage cavity 2, which will not cause the liquid to splash due to the turbulent air flow, and also maximally avoids the accidental outflow of liquid from the air inlet 61 and the air outlet 74.

[0064] The above embodiments are only for illustrating the technical concept and characteristics of the present invention, and their purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly. It cannot be used to limit the protection scope of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended to include all changes that fall within the meaning and scope of the equivalent elements of the claims in the present invention.
