Description

Technical Field

[0001] The present application belongs to the technical field of medical devices, and specifically relates to a humidification tank for a ventilator. Background Art

[0002] A ventilator is generally equipped with a blower. The air outlet of the blower interacts with the user through external pipes and a mask. The humidified air makes the user feel more comfortable and is easier to be accepted by the user. Therefore, the humidification component has gradually become one of the essential components of the ventilator.

[0003] The humidification component is usually a humidification tank installed in the ventilator, which has a gas channel inside and is filled with humidification liquid. The gas blown out by the blower enters the interior of the humidification tank through the gas channel and comes into contact with the humidification liquid, thereby making the gas moist. The moistened gas then flows out from the outlet of the humidification tank to the user end to assist the user in breathing.

[0004] At present, the connection method between the humidifier tank and the ventilator is usually to set a accommodating cavity at the end of the ventilator host, and one end of the humidifier tank extends into the accommodating cavity to realize the connection between the humidifier tank and the ventilator host. This results in a larger volume of the whole machine, thereby increasing the burden of users to carry it when going out; in addition, the humidifier tank can only be suitable for one model of ventilator, which affects the flexibility of the humidifier tank. Summary of the invention

[0005] The present application provides a humidifier tank for a ventilator to reduce the burden of users carrying the humidifier when going out, increase the flexibility of the humidifier tank, and improve the user experience.

[0006] The technical solution adopted in this application is:

[0007] A humidification tank for a ventilator, comprising:

[0008] A housing, wherein a liquid storage cavity is formed inside the housing and a connecting portion for connecting to a main unit of a ventilator is provided outside the housing;

[0009] An air intake pipeline, the air intake pipeline comprising a first air intake port and a first air outlet, an air intake flow passage being formed between the first air intake port and the first air outlet;

[0010] an air outlet pipeline, the air outlet pipeline comprising a second air inlet and a second air outlet, an air outlet passage being formed between the second air inlet and the second air outlet;

[0011] The first air inlet and the second air outlet are respectively located on different sides of the shell, and the first air outlet and the second air inlet are both located in the liquid storage chamber and have a certain distance from the inner wall of the shell. When the amount of liquid inside the humidification tank is at the maximum liquid level, the humidification tank is rotated at any angle, and the liquid level of the liquid is lower than the height of the first air outlet and the second air inlet, so that the liquid cannot enter the inlet flow channel and the outlet flow channel.

[0012] By adopting the above-mentioned technical scheme, when using the humidification tank in the present application, the first air inlet is connected to the air outlet of the ventilator, so that the gas generated by the ventilator enters the inlet flow channel through the first air inlet, and the gas flows along the inlet flow channel and enters the liquid storage chamber through the first air outlet. The gas entering the liquid storage chamber contacts the liquid in the liquid storage chamber so that the gas becomes moistened. The moistened gas then enters the outlet flow channel through the second air inlet and flows out to the user end through the second air outlet to treat the user.

[0013] The connection method between the humidifier tank and the ventilator in the present application is more flexible, thereby avoiding the need to set up a accommodating chamber in the ventilator, thereby reducing the volume of the entire machine, reducing the burden on users to carry it when going out, and achieving the effect of being convenient for users to carry it when going out; and the humidifier tank in the present application can be separated from the ventilator, and then the humidifier tank can be cleaned and disinfected separately to extend the service life of the humidifier tank, thereby improving the user experience.

[0014] Furthermore, since the first air inlet and the second air outlet in the present application are respectively located on different sides of the shell, on the one hand, it avoids the situation where the ventilator needs to be designed to avoid the first air inlet and the second air outlet being located on the same side of the shell, thereby simplifying the structural design of the ventilator, and at the same time enables the humidifier tank in the present application to be adapted to various models of ventilators to increase the flexibility of the humidifier tank; on the other hand, it is more convenient to miniaturize the humidifier tank to reduce the volume and weight of the humidifier tank, so as to further achieve the effect of being easy for users to carry, thereby further improving the user experience.

[0015] In addition, since the first air outlet and the second air inlet are at a certain distance from the inner wall of the shell, when the amount of liquid in the liquid storage chamber is at the maximum liquid level, the humidification tank is rotated at any angle, and the liquid level is lower than the height of the first air outlet and the second air inlet, thereby avoiding the situation where the liquid in the liquid storage chamber may enter the inlet air channel through the first air outlet and cause a malfunction of the ventilator, thereby ensuring the service life of the ventilator, and at the same time avoiding the situation where the liquid in the liquid storage chamber may enter the outlet air channel through the second air inlet and flow to the user end to affect the user experience, thereby further improving the user experience.

[0016] Optionally, the first air outlet and / or the second air inlet are arranged close to the center of the liquid storage cavity.

[0017] By adopting the above technical solution, since the first air outlet and the second air inlet are arranged close to the center of the liquid storage chamber, on the one hand, it further avoids the situation where the liquid in the liquid storage chamber enters the inlet flow channel and the air outlet channel when the humidification tank rotates, so as to further ensure the service life of the ventilator and further improve the user experience; on the other hand, it increases the maximum amount of liquid that can be accommodated in the liquid storage chamber, so as to reduce the user's frequency of adding liquid and extend the sustainable working time of the humidification tank, thereby further improving the user experience.

[0018] Optionally, an air outlet blocking plate opposite to the first air outlet is provided in the liquid storage cavity, and the air outlet blocking plate is spaced apart from the first air outlet;

[0019] And / or, an air inlet blocking plate opposite to the second air inlet is arranged in the liquid storage chamber, and the air inlet blocking plate is arranged at a distance from the second air inlet.

[0020] By adopting the above technical scheme, since the air outlet blocking plate is arranged relative to the first air outlet, on the one hand, the air outlet blocking plate can block in the opening direction of the first air outlet, so as to further prevent the liquid from entering the inlet flow channel through the first air outlet when the humidification tank rotates, thereby further reducing the failure rate of the ventilator to further ensure the service life of the ventilator; on the other hand, the air outlet blocking plate can block the gas flowing out through the first air outlet, so that the gas is more dispersed when entering the liquid storage chamber, so as to increase the contact area between the gas and the liquid, and then increase the wetting effect on the gas, so as to further improve the user experience; and since the air outlet blocking plate is spaced apart from the first air outlet, it is ensured that the gas in the inlet flow channel can be discharged normally through the first air outlet to ensure the wetting effect on the gas.

[0021] Since the air inlet blocking plate is arranged relative to the second air inlet, on the one hand, the air inlet blocking plate can block in the opening direction of the second air inlet, so as to further prevent the liquid from entering the outlet flow channel through the second air inlet when the humidification tank rotates, thereby further preventing the liquid from entering the user end, so as to further improve the user experience; on the other hand, the air inlet blocking plate can also block the gas that is about to enter the second air inlet, so as to make the flow path of the gas in the liquid storage chamber more tortuous, so as to further increase the wetting effect on the gas, thereby further improving the user experience; and since the air inlet blocking plate is spaced apart from the second air inlet, it is ensured that the gas in the liquid storage chamber can enter the outlet flow channel through the second air inlet, so as to ensure the therapeutic effect on the user.

[0022] Optionally, the area of ​​the air outlet blocking plate is greater than or equal to the outlet area of ​​the first air outlet;

[0023] And / or, the area of ​​the air intake blocking plate is greater than or equal to the inlet area of ​​the second air intake port.

[0024] By adopting the above technical scheme, since the area of ​​the gas outlet blocking plate is greater than or equal to the outlet area of ​​the first gas outlet, on the one hand, the gas outlet blocking plate can completely block the first gas outlet in the opening direction of the first gas outlet, so as to improve the blocking effect of the gas outlet blocking plate on the first gas outlet, so as to further avoid the liquid in the liquid storage chamber from entering the inlet flow channel, and on the other hand, the blocking effect of the gas outlet blocking plate on the gas flowing out through the first gas outlet is improved, so as to further improve the wetting effect on the gas.

[0025] Since the area of ​​the air inlet blocking plate is greater than or equal to the air inlet area of ​​the second air inlet, on the one hand, the air inlet blocking plate can completely block the second air inlet in the opening direction of the second air inlet, so as to improve the blocking effect of the air inlet blocking plate on the second air inlet, so as to further prevent the liquid in the liquid storage chamber from entering the outlet flow channel, and on the other hand, the blocking effect of the air outlet blocking plate on the gas flowing to the second air outlet is improved, so as to further improve the wetting effect on the gas.

[0026] Optionally, the inlet flow channel includes a first inlet flow channel extending outside the liquid storage chamber and a second inlet flow channel located inside the liquid storage chamber, and the first inlet flow channel and the second inlet flow channel are connected to each other;

[0027] The outlet flow channel includes a first outlet flow channel extending outside the liquid storage chamber and a second outlet flow channel located inside the liquid storage chamber, and the first outlet flow channel and the second outlet flow channel are connected to each other.

[0028] By adopting the above technical solution, since the inlet flow channel includes a first inlet flow channel extending outside the liquid storage chamber, it is possible to facilitate the connection between the humidifier tank and the ventilator, thereby improving the installation efficiency of the humidifier tank to the ventilator, and at the same time greatly reducing the difficulty of installing the humidifier tank on the ventilator.

[0029] Since the outlet air channel includes a first outlet air channel extending outside the liquid storage chamber, it is possible to facilitate the connection of the humidification tank with the pipeline connected to the user end, thereby improving the assembly efficiency of the humidification tank and the user end together, and at the same time can greatly reduce the difficulty of assembling the humidification tank and the user end together.

[0030] Optionally, the second inlet air channel and the second outlet air channel are arranged in parallel.

[0031] By adopting the above technical solution, since the second inlet air channel and the second outlet air channel are arranged in parallel, the regularity of the internal structure of the shell is increased, thereby reducing the difficulty of assembling the humidification tank and further improving the assembly efficiency of the humidification tank.

[0032] Optionally, the first air outlet and the second air inlet have the same orientation, and a baffle is provided between the first air outlet and the second air inlet, and the baffle extends from between the first air outlet and the second air inlet in a direction away from the second inlet flow channel and the second outlet flow channel.

[0033] By adopting the above technical solution, since the first air outlet and the second air inlet are oriented in the same direction, the resistance of the gas flowing in the liquid storage chamber is reduced, so that the gas can more easily enter the outlet flow channel through the second air inlet to ensure the smoothness of the gas flow. In addition, since a baffle is provided between the first air outlet and the second air inlet, the baffle can isolate the first air outlet and the second air inlet to ensure that the gas flowing out through the first air outlet contacts the liquid and then enters the outlet flow channel through the second air inlet, that is, it is avoided that the gas flowing out through the first air outlet directly enters the outlet flow channel through the second air inlet, thereby ensuring the wetting effect of the gas, so as to further improve the user experience.

[0034] Optionally, the second inlet air passage and the second outlet air passage are symmetrically arranged along the baffle.

[0035] By adopting the above technical solution, since the second inlet air flow channel and the second outlet air flow channel are symmetrically arranged along the baffle plate, the isolation effect of the baffle plate on the first air outlet and the second air inlet is increased, and at the same time the structure inside the shell is more regular, so as to further achieve the effect of facilitating the assembly of the humidification tank.

[0036] Optionally, the first inlet air flow channel and the second inlet air flow channel are perpendicular to each other; the first outlet air flow channel and the second outlet air flow channel are perpendicular to each other.

[0037] By adopting the above technical solution, since the first inlet flow channel and the second inlet flow channel are perpendicular to each other, the direction of the first air inlet and the direction of the first air outlet are perpendicular to each other, and the first outlet flow channel and the second outlet flow channel are perpendicular to each other, so that the direction of the second air inlet and the direction of the second air outlet are perpendicular to each other, so as to increase the maximum amount of liquid that can be accommodated in the liquid storage chamber, so as to further reduce the user's frequency of adding liquid and extend the sustainable working time of the humidification tank.

[0038] Optionally, the first inlet air passage and the first outlet air passage are arranged along a common central axis.

[0039] By adopting the above technical solution, since the first inlet air channel and the first outlet air channel are arranged on the same central axis, the stability of the humidifier tank is increased when the gas flows through the humidifier tank. At the same time, the connection position between the humidifier tank and the ventilator is coaxial with the connection position between the humidifier tank and the user end to avoid the humidifier tank from easily deflecting, thereby increasing the stability of the humidifier tank.

[0040] Optionally, the shell is provided with an avoidance groove, at least a portion of the air outlet pipeline is located in the avoidance groove, and the height of the second air outlet is not greater than the top height of the avoidance groove.

[0041] By adopting the above technical scheme, since at least part of the air outlet pipeline is located in the avoidance groove, after the external pipeline connected to the user end is connected to the air outlet pipeline, the external pipeline can contact the groove wall of the avoidance groove to increase the connection stability between the external pipeline and the air outlet pipeline; and the height at the second air outlet is not greater than the top height of the avoidance groove, so that the second air outlet can be hidden in the avoidance groove, thereby further reducing the volume of the humidification tank and making the external shape of the humidification tank more regular, so as to further achieve the effect of making it easier for users to carry the humidification tank. In addition, the outer side of the shell can protect the second air outlet to reduce the damage of the air outlet pipeline due to collision of the humidification tank, thereby ensuring the service life of the humidification tank.

[0042] Optionally, the outer wall of the avoidance groove is provided with a snap groove for connecting an external pipeline.

[0043] By adopting the above technical solution, since the outer wall of the avoidance groove is provided with a snap groove, after the external pipeline is assembled on the air outlet pipeline, the clamping block on the external pipeline can extend into the snap groove and engage with the snap groove to avoid the external pipeline being separated from the air outlet pipeline due to being pulled, thereby further increasing the connection stability between the external pipeline and the air outlet pipeline.

[0044] Optionally, the shell is provided with a liquid discharge port connected to the liquid storage chamber, and a sealing member detachably connected to the shell is provided at the liquid discharge port, and the sealing member is used to seal the liquid discharge port.

[0045] By adopting the above technical solution, since a seal detachably connected to the shell is provided at the drain port, the liquid in the liquid storage chamber can be discharged through the drain port, so as to avoid the liquid from being deteriorated and producing odor due to long-term storage in the liquid storage chamber, thereby improving the user experience; at the same time, when the user cleans the liquid storage chamber, the cleaning water can also be discharged from the drain port, so as to achieve the effect of facilitating the user to clean the liquid storage chamber.

[0046] Optionally, the sealing member includes a connecting end and a movable end, the connecting end is hinged to the shell, and the movable end is provided with an elastic member, and the elastic member can abut against the drain port to seal the drain port.

[0047] By adopting the above technical solution, since the connecting end is hinged to the shell and the movable end is provided with an elastic member, when opening or sealing the discharge port, it is only necessary to apply pressure toward the discharge port or away from the discharge port to the movable end to make the movable end rotate around the connecting end, thereby simplifying the operation steps for opening or sealing the discharge port and reducing the difficulty of operation, so as to achieve the effect of facilitating the opening or sealing of the discharge port.

[0048] Optionally, it further includes a sealing rib, wherein the sealing rib and the shell together form a liquid storage cavity, and the liquid discharge port is arranged at the connection between the sealing rib and the shell.

[0049] By adopting the above technical solution, since the drain port is arranged at the connection between the sealing rib and the shell, the drain port is located at the corner of the shell, so that all the liquid in the liquid storage cavity can be discharged through the drain port, so as to increase the cleanliness of the liquid storage cavity, and further avoid the situation where the liquid remaining in the liquid storage cavity may deteriorate and produce odor, thereby further improving the user experience.

[0050] Optionally, the sealing member comprises a connecting plate and a sealing plate connected to each other, and the elastic member is sleeved on the end of the sealing plate;

[0051] The sealing member further comprises a locking plate connected to the sealing plate, one end of the locking plate forms a force-bearing portion, and the other end forms a locking portion for buckling with the shell.

[0052] By adopting the above technical solution, when the drain port is opened, the force-bearing part is pressed in the direction of the sealing plate to rotate the locking plate, and then the locking part moves in the direction away from the sealing plate, so that the locking part is released from the snapping with the shell, and then pressure is applied to the connecting plate away from the drain port, so that the connecting plate drives the sealing plate and the locking plate to rotate, and finally the elastic part is separated from the drain port to complete the opening of the drain port.

[0053] By setting the locking plate, on the one hand, the connection stability between the seal and the shell is increased when the seal is used to seal the drain port, so as to ensure the sealing effect of the drain port. On the other hand, it is easy to release the engagement between the locking part and the shell, so as to facilitate the opening of the drain port.

[0054] Optionally, a guide rib is provided in the liquid storage cavity, and the guide rib forms a guide slope, and the guide slope is used to guide the liquid to the liquid discharge port.

[0055] By adopting the above technical solution, when discharging the liquid in the liquid storage chamber, the shell is rotated so that the discharge port is located at the lowest point of the shell, and then the liquid in the liquid storage chamber is completely discharged through the discharge port under the guidance of the guide slope, so as to further avoid the occurrence of liquid residue in the liquid storage chamber, thereby further improving the user experience.

[0056] Optionally, the sealing member is a flexible sealing plug.

[0057] By adopting the above technical solution, since the seal is a flexible sealing plug, the sealing effect of the seal on the drain port is increased, so that when opening or sealing the drain port, it is only necessary to pull or press the flexible sealing plug, thereby achieving the effect of facilitating the sealing or opening of the drain port; at the same time, the structure of the seal is simplified and the production cost of the seal is reduced, thereby reducing the production cost of the humidification tank; in addition, there is no need to make an avoidance design for the corresponding flexible sealing plug on the shell, so as to further increase the maximum amount of liquid that can be accommodated in the liquid storage chamber.

[0058] Optionally, the shell is provided with a maximum liquid level line, and when the height of the liquid reaches the maximum liquid level line, the volume of the liquid accounts for at most one third of the total volume of the liquid storage chamber.

[0059] By adopting the above technical solution, since the shell is provided with a maximum liquid level line, when liquid is added to the liquid storage chamber, the maximum liquid level line can serve as a reference for the user, so as to facilitate the user to add an appropriate amount of liquid to the liquid storage chamber; at the same time, it also avoids the situation where the user adds too much liquid into the liquid storage chamber, causing the liquid to enter the inlet and outlet air channels, so as to ensure the service life of the ventilator and increase the user's experience.

[0089] When using the humidifier tank in the present application, the first air inlet 211 is connected to the air outlet of the ventilator, so that the gas generated by the ventilator enters the inlet flow channel through the first air inlet 211, the gas flows along the inlet flow channel and enters the liquid storage chamber 13 through the first air outlet 221, the gas entering the liquid storage chamber 13 contacts the liquid contained in the liquid storage chamber 13, so that the gas becomes moistened, and the moistened gas enters the outlet flow channel through the second air inlet 321 and flows out to the user end through the second air outlet 311 to treat the user.

[0090] The connection method between the humidifier tank and the ventilator in the present application is more flexible. It can be connected to the ventilator by means of a tapered joint, a snap, a thread, an external pipeline, etc., thereby avoiding the need to set up a accommodating chamber in the ventilator, thereby reducing the volume of the entire machine, reducing the burden on users to carry it when going out, and achieving the effect of making it easier for users to carry it when going out; and the humidifier tank in the present application can be separated from the ventilator, and then the humidifier tank can be cleaned and disinfected separately to extend the service life of the humidifier tank, thereby improving the user experience.

[0091] Furthermore, since the first air inlet 211 and the second air outlet 311 in the present application are respectively located on different sides of the shell 1, on the one hand, it avoids the situation where the ventilator needs to be designed to avoid the first air inlet 211 and the second air outlet 311 being located on the same side of the shell 1, thereby simplifying the structural design of the ventilator, and at the same time, it enables the humidifier tank in the present application to be adapted to various models of ventilators to increase the flexibility of the humidifier tank; on the other hand, it is more convenient to miniaturize the humidifier tank to reduce the volume and weight of the humidifier tank, so as to further achieve the effect of being easy for users to carry, thereby further improving the user experience.

[0092] In addition, since the first air outlet 221 and the second air inlet 321 are at a certain distance from the inner wall of the shell 1, when the amount of liquid in the liquid storage chamber 13 is at the maximum liquid level, the humidification tank is rotated at any angle, and the liquid level is lower than the height of the first air outlet 221 and the second air inlet 321, thereby avoiding the liquid in the liquid storage chamber 13 from entering the inlet flow channel through the first air outlet 221 and causing a malfunction of the ventilator, thereby ensuring the service life of the ventilator, and at the same time avoiding the liquid in the liquid storage chamber 13 from entering the outlet flow channel through the second air inlet 321 and flowing to the user end to affect the user experience, thereby further improving the user experience.

[0093] The connecting part is used to be connected to the ventilator host, so that the humidifier tank can be connected to the ventilator host to increase the integrity of the humidifier tank and the ventilator host, thereby increasing the stability of the humidifier tank.

[0094] It should be noted that the humidifier tank of the present application may or may not have a heating function. As a preferred embodiment, the humidifier tank of the present application does not have a heating function and is not electrically connected to the ventilator, so as to further reduce the volume and weight of the humidifier tank, thereby further achieving the effect of being convenient for users to carry it.

[0095] Specifically, the shell 1 where the air inlet end of the humidifier tank is located is called the air inlet end wall, the shell 1 where the air outlet end is located is called the air outlet end wall, and the shell between the air inlet end wall and the air outlet end wall is called the side wall. Along the extension direction of the side wall, the cross-sectional shape of the humidifier tank is adapted to the shape of the ventilator host to enhance the integrity of the humidifier tank and the ventilator host, for example, it can be a rounded rectangle.

[0096] The present application does not specifically limit the structure of the connecting portion. Fig.10 It can be a rib 17 set on the outer edge of the air inlet end wall, which is used to interference fit with the ventilator host to achieve the connection between the humidifier tank and the host; and / or, an annular groove 18 set on the air inlet end wall, which is used to interference fit with the ventilator host to achieve the connection between the humidifier tank and the host.

[0097] Specifically, Fig. 9 The placement position of the humidification tank shown in the figure is taken as the first position. At this time, the internal cross-sectional view of the humidification tank when the liquid level reaches the maximum is as shown in FIG. Fig.10 As shown, the cross-sectional view of the humidification tank obtained by rotating the humidification tank 45° to the left from the first orientation is as shown in Fig.11 As shown, after rotating 90° to the left, the cross-sectional view of the humidification tank is as follows Figure 2 As shown, the cross-sectional view of the humidification tank obtained by rotating 180° to the left is as follows Fig.12 As shown, the cross-sectional view of the humidification tank obtained by rotating the humidification tank 90° to the right from the first orientation is as shown in Figure 3 As shown, the cross-sectional view of the humidification tank obtained by rotating the humidification tank forward or backward by 90° from the first position is as shown in Figure 4 As shown, it can be seen from the above figure that when the liquid is at the maximum liquid level, the liquid level of the liquid is lower than the height of the first air outlet 221 and the second air inlet 321 when the humidification tank is rotated at any angle.

[0098] In one embodiment, the first air outlet 221 is disposed near the center of the liquid storage chamber 13 to prevent the liquid in the liquid storage chamber 13 from entering the inlet flow channel through the first air outlet 221 when the humidification tank rotates, thereby ensuring the service life of the ventilator.

[0099] In another embodiment, the second air inlet 321 is disposed near the center of the liquid storage chamber 13 to prevent the liquid in the liquid storage chamber 13 from entering the outlet flow channel through the second air inlet 321 when the humidification tank rotates, so as to further improve the user experience.

[0100] In a preferred embodiment, referring to Figure 2 , Figure 3 , Figure 5 and Figure 6 The first air outlet 221 and the second air inlet 321 are both arranged close to the center of the liquid storage chamber 13. On the one hand, it further avoids the situation that the liquid in the liquid storage chamber 13 enters the inlet flow channel and the air outlet channel when the humidification tank rotates, so as to further ensure the service life of the ventilator and further improve the user experience; on the other hand, it increases the maximum amount of liquid that can be accommodated in the liquid storage chamber 13, so as to reduce the user's frequency of adding liquid and extend the sustainable working time of the humidification tank, thereby further improving the user experience.

[0101] It should be noted that the "maximum amount of liquid that can be contained in the liquid storage chamber 13" mentioned in the present application does not refer to the maximum capacity of the liquid storage chamber 13, but refers to the maximum capacity of the liquid that cannot enter the inlet and outlet channels when the humidification tank rotates.

[0102] In a preferred embodiment, referring to Figure 2 , Figure 3 , Figure 5 and Figure 6 , an air outlet blocking plate 222 is provided in the liquid storage chamber 13 opposite to the first air outlet 221. On the one hand, the air outlet blocking plate 222 can block the opening direction of the first air outlet 221 to further prevent the liquid from entering the inlet flow channel through the first air outlet 221 when the humidification tank rotates or shakes, thereby further reducing the failure rate of the ventilator to further ensure the service life of the ventilator. On the other hand, the air outlet blocking plate 222 can block the gas flowing out through the first air outlet 221, so that the gas is more dispersed when entering the liquid storage chamber 13, so as to increase the contact area between the gas and the liquid, thereby increasing the wetting effect on the gas, and further improving the user experience. In addition, the air outlet blocking plate 222 is spaced apart from the first air outlet 221, thereby ensuring that the gas in the inlet flow channel can be discharged normally through the first air outlet 221 to ensure the wetting effect on the gas.

[0103] Furthermore, the area of ​​the gas outlet blocking plate 222 is greater than or equal to the outlet area of ​​the first gas outlet 221. On the one hand, the gas outlet blocking plate 222 can completely block the first gas outlet 221 in the opening direction of the first gas outlet 221, so as to improve the blocking effect of the gas outlet blocking plate 222 on the first gas outlet 221, so as to further prevent the liquid in the liquid storage chamber 13 from entering the inlet flow channel. On the other hand, the blocking effect of the gas outlet blocking plate 222 on the gas flowing out through the first gas outlet 221 is improved, so as to further improve the wetting effect on the gas.

[0104] In a preferred embodiment, referring to Figure 2 , Figure 3 , Figure 5 and Figure 6 , an air inlet blocking plate 322 is provided in the liquid storage chamber 13 opposite to the second air inlet 321. On the one hand, the air inlet blocking plate 322 can block the opening direction of the second air inlet 321 to further prevent the liquid from entering the outlet flow channel through the second air inlet 321 when the humidification tank rotates or shakes, thereby further preventing the liquid from entering the user end, thereby further improving the user experience. On the other hand, the air inlet blocking plate 322 can also block the gas that is about to enter the second air inlet 321, so that the flow path of the gas in the liquid storage chamber 13 is more tortuous, thereby further increasing the wetting effect on the gas, thereby further improving the user experience. In addition, the air inlet blocking plate 322 is spaced apart from the second air inlet 321, thereby ensuring that the gas in the liquid storage chamber 13 can enter the outlet flow channel through the second air inlet 321 to ensure the treatment effect on the user.

[0105] Furthermore, the area of ​​the air inlet blocking plate 322 is greater than or equal to the inlet area of ​​the second air inlet port 321. On the one hand, the air inlet blocking plate 322 can completely block the second air inlet port 321 in the opening direction of the second air inlet port 321, so as to improve the blocking effect of the air inlet blocking plate 322 on the second air inlet port 321, so as to further prevent the liquid in the liquid storage chamber 13 from entering the outlet flow channel. On the other hand, the blocking effect of the air outlet blocking plate 222 on the gas flowing toward the second air outlet 311 is improved, so as to further improve the wetting effect on the gas.

[0106] Specifically, the present application does not specifically limit the relative positional relationship between the outlet blocking plate 222 and the inlet blocking plate 322. The outlet blocking plate 222 and the inlet blocking plate 322 may be located on the same plane or not; preferably, the outlet blocking plate 222 and the inlet blocking plate 322 are located on the same plane. Further, when the humidifier tank is rotated 90° to the left or right from the first position, the liquid level is lower than the plane height where the outlet blocking plate 222 and the inlet blocking plate 322 are located, so as to further ensure the blocking effect on the liquid.

[0107] The present application does not specifically limit the positional relationship between the inlet and outlet channels and the liquid storage chamber 13. Preferably, refer to Figure 2 and Figure 3 The inlet flow channel includes a first inlet flow channel 21 extending from the outside of the liquid storage chamber 13 and a second inlet flow channel 22 located inside the liquid storage chamber 13, and the first inlet flow channel 21 and the second inlet flow channel 22 are connected to each other; the outlet flow channel includes a first outlet flow channel 31 extending from the outside of the liquid storage chamber 13 and a second outlet flow channel 32 located inside the liquid storage chamber 13, and the first outlet flow channel 31 and the second outlet flow channel 32 are connected to each other.

[0108] That is, both the inlet flow channel and the outlet flow channel have a portion located inside the liquid storage chamber 13 and a portion located outside the liquid storage chamber 13 .

[0109] It can be understood that the first air inlet 211 is located at the end of the first inlet air duct 21 away from the second inlet air duct 22, and the first air outlet 221 is located at the end of the second inlet air duct 22 away from the first inlet air duct 21; the second air inlet 321 is located at the end of the second outlet air duct 32 away from the first outlet air duct 31, and the second air outlet 311 is located at the end of the first outlet air duct 31 away from the second outlet air duct 32.

[0110] Since the inlet flow channel includes the first inlet flow channel 21 extending out of the liquid storage chamber 13, the humidifier tank can be easily connected to the ventilator, thereby improving the installation efficiency of the humidifier tank to the ventilator, and at the same time greatly reducing the difficulty of installing the humidifier tank to the ventilator. Since the outlet flow channel includes the first outlet flow channel 31 extending out of the liquid storage chamber 13, the humidifier tank can be easily connected to the pipeline connected to the user end, thereby improving the assembly efficiency of assembling the humidifier tank and the user end, and at the same time greatly reducing the difficulty of assembling the humidifier tank and the user end.

[0111] The present application does not specifically limit the positional relationship between the second inlet air passage 22 and the second outlet air passage 32. Preferably, refer to Figure 2 and Figure 3 The second inlet air channel 22 and the second outlet air channel 32 are arranged in parallel to increase the regularity of the internal structure of the shell 1, thereby reducing the difficulty of assembling the humidification tank and further improving the assembly efficiency of the humidification tank.

[0112] Further, see Figure 2 and Figure 3 The first air outlet 221 and the second air inlet 321 are oriented in the same direction, thereby reducing the resistance of the gas flowing in the liquid storage chamber 13, so that the gas can more easily enter the outlet flow channel through the second air inlet 321 to ensure the smoothness of the gas flow. At the same time, the first air outlet 221 and the second air inlet 321 can be made as close to the center position of the liquid storage chamber 13 as possible to further increase the maximum amount of liquid that can be accommodated in the liquid storage chamber 13. In addition, a baffle 323 is provided between the first air outlet 221 and the second air inlet 321, and the baffle 323 extends from between the first air outlet 221 and the second air inlet 321 in a direction away from the second inlet flow channel 22 and the second outlet flow channel 32, so that the baffle 323 can isolate the first air outlet 221 and the second air inlet 321 to ensure that the gas flowing out through the first air outlet 221 contacts the liquid and then enters the outlet flow channel through the second air inlet 321, that is, it avoids the situation that the gas flowing out through the first air outlet 221 directly enters the outlet flow channel through the second air inlet 321, thereby extending the flow path of the gas, thereby ensuring the wetting effect of the gas, and further improving the user experience.

[0113] Furthermore, the second inlet air flow channel 22 and the second outlet air flow channel 32 are symmetrically arranged along the baffle plate 323, thereby increasing the isolation effect of the baffle plate 323 on the first air outlet 221 and the second air inlet 321, and at the same time making the structure inside the shell 1 more regular, so as to further achieve the effect of facilitating the assembly of the humidification tank.

[0114] The present application does not specifically limit the configuration of the baffle 323, which may be as follows: Figure 2 and Figure 3 The wall structure formed by the extension of the channel wall of the second outlet channel 32 close to the second outlet channel can also be a rib plate structure arranged on the wall of the liquid storage chamber 13. When the baffle plate 323 is a wall structure formed by the extension of the channel wall of the second outlet channel 32, both the inlet blocking plate 322 and the outlet blocking plate 222 can be arranged at one end of the baffle plate 323 away from the second inlet channel 22 and the second outlet channel 32, or one of the inlet blocking plate 322 and the outlet blocking plate 222 is arranged on the baffle plate 323, and the other is arranged on the wall of the liquid storage chamber 13.

[0115] In other embodiments, the first inlet flow channel 21 and the second outlet flow channel 32 are coaxially arranged, so that the first air outlet 221 and the second air inlet 321 are arranged opposite to each other, and the baffle plate 323 is located between the first air outlet 221 and the second air inlet 321, and the area of ​​the baffle plate 323 is larger than the outlet area of ​​the first air outlet 221 and the inlet area of ​​the second air inlet 321, so as to avoid the gas flowing out through the first air outlet 221 directly entering the outlet flow channel through the second air inlet 321, thereby ensuring the wetting effect of the gas; in this embodiment, the setting of the inlet blocking plate 322 and the outlet blocking plate 222 can be cancelled, or it can be understood that the inlet blocking plate 322, the outlet blocking plate 222 and the baffle plate 323 are combined into one. Of course, the first inlet flow channel 21 and the second outlet flow channel 32 can also be arranged at an angle.

[0116] Further, see Figure 2 and Figure 3 The first inlet flow channel 21 and the second inlet flow channel 22 are perpendicular to each other; the first outlet flow channel 31 and the second outlet flow channel 32 are perpendicular to each other, so that the direction of the first air inlet 211 and the direction of the first air outlet 221 are perpendicular to each other, and the direction of the second air inlet 321 and the direction of the second air outlet 311 are perpendicular to each other, so as to increase the maximum amount of liquid that can be accommodated in the liquid storage chamber 13, so as to further reduce the user's frequency of adding liquid and extend the sustainable working time of the humidification tank.

[0117] The present application does not specifically limit the positional relationship between the first inlet flow channel 21 and the first outlet flow channel 31. Preferably, refer to Figure 2 and Figure 3 , the first inlet air channel 21 and the first outlet air channel 31 are arranged with the same central axis, thereby increasing the stability of the humidifier when the gas flows through the humidifier, and at the same time making the connection position between the humidifier and the ventilator coaxial with the connection position between the humidifier and the user end, so as to avoid the humidifier from easily deflecting, thereby increasing the stability of the humidifier. In other embodiments, the central axes of the first inlet air channel 21 and the first outlet air channel 31 can also be arranged in parallel and spaced apart or at an angle.

[0118] In other embodiments, the inlet flow channel and the outlet flow channel may also be completely located inside the liquid storage chamber 13 , and the first air inlet 211 and the second air outlet 311 are both located on the outer wall surface of the shell 1 .

[0119] In a preferred embodiment, referring to Figures 2 to 6 The shell 1 is provided with an avoidance groove 14 , at least part of the air outlet pipeline 3 is located in the avoidance groove 14 , and the height of the second air outlet 311 is not greater than the top height of the avoidance groove 14 .

[0120] It should be noted that the height of the second air outlet 311 is not greater than the top height of the avoidance groove 14, which means that the second air outlet 311 does not protrude from the outer wall surface of the shell 1, that is, the second air outlet 311 is flush with the outer wall surface of the shell 1 or recessed in the outer wall surface of the shell 1.

[0121] It can be understood that the first outlet flow channel 31 is located in the avoidance groove 14, so that after the external pipeline connected to the user end is connected to the air outlet pipeline 3, the external pipeline can contact the groove wall of the avoidance groove 14 to increase the connection stability between the external pipeline and the air outlet pipeline 3; and the height of the second air outlet 311 is not greater than the top height of the avoidance groove 14, so that the second air outlet 311 can be hidden in the avoidance groove 14, thereby further reducing the volume of the humidification tank and making the external shape of the humidification tank more regular, so as to further achieve the effect of facilitating the user to carry the humidification tank, and in addition, the outer side of the shell 1 can protect the second air outlet 311 to reduce the damage of the air outlet pipeline 3 due to the collision of the humidification tank, thereby ensuring the service life of the humidification tank; in addition, Fig. 9 As shown, when humidifying liquid is added to the humidifying tank from the first air inlet 211, the height at the second air outlet 311 is not greater than the top height of the avoidance groove 14, which can ensure that the end face where the second air outlet 311 is located can be placed horizontally on a plane, making it easier for users to add humidifying liquid.

[0122] Further, see Figure 4 and Figure 7 The outer wall of the avoidance groove 14 is provided with a snap groove 141 for connecting the external pipeline, so that after the external pipeline is assembled on the air outlet pipeline 3, the clamping block on the external pipeline can extend into the snap groove 141 and engage with the snap groove 141 to avoid the external pipeline being separated from the air outlet pipeline 3 due to being pulled, thereby further increasing the connection stability between the external pipeline and the air outlet pipeline 3.

[0123] In a preferred embodiment, referring to Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The shell 1 is provided with a drain port 15 connected to the liquid storage chamber 13. A seal 4 detachably connected to the shell 1 is provided at the drain port 15. The seal 4 is used to seal the drain port 15, so that the liquid in the liquid storage chamber 13 can be discharged through the drain port 15, so as to avoid the liquid from being deteriorated and producing odor due to long-term storage in the liquid storage chamber 13, thereby improving the user experience; at the same time, when the user cleans the liquid storage chamber 13, the cleaning water can also be discharged from the drain port 15, so as to achieve the effect of facilitating the user to clean the liquid storage chamber 13.

[0124] The present application does not specifically limit the structure of the sealing member 4, which may adopt any one of the following embodiments:

[0125] Embodiment 1. In this embodiment, referring to Figure 2 , Figure 3 , Figure 5 and Figure 7 The sealing member 4 includes a connecting end and a movable end. The connecting end is hinged to the shell 1. The movable end is provided with an elastic member 44. The elastic member 44 can abut against the drain port 15 to seal the drain port 15. Then, when the drain port 15 is opened or sealed, it is only necessary to apply pressure toward the drain port 15 or away from the drain port 15 to the movable end to make the movable end rotate around the connecting end, thereby simplifying the operation steps for opening or sealing the drain port 15 and reducing the difficulty of operation, so as to achieve the effect of facilitating the opening or sealing of the drain port 15.

[0126] Further, see Figure 3 and Figure 5 The humidification tank further includes a sealing rib 16 , which together with the shell 1 forms a liquid storage chamber 13 , and a liquid discharge port 15 is disposed at the connection between the sealing rib 16 and the shell 1 .

[0127] It can be understood that the shell 1 is recessed inward to form an escape space, and the wall of the escape space forms a sealing rib 16. When the seal 4 closes the drain port 15, at least part of the seal 4 is located in the escape space to reduce the volume of the humidification tank.

[0128] Since the drain port 15 is arranged at the connection between the sealing rib 16 and the shell 1, the drain port 15 is located at the corner of the shell 1, so that all the liquid in the liquid storage chamber 13 can be discharged through the drain port 15, so as to increase the cleanliness of the liquid storage chamber 13, and further avoid the situation that the liquid remaining in the liquid storage chamber 13 may deteriorate and produce odor, thereby further improving the user experience.

[0129] Specifically, the horizontal plane where the sealing rib 16 is located can be flush with the edge of the second air inlet 321. This setting makes the horizontal plane where the sealing rib 16 is located become the maximum liquid level line. When the liquid level of the added liquid exceeds the horizontal plane where the sealing rib 16 is located, the liquid will flow out from the second air inlet 321, which is convenient for the user to control the amount of liquid added and control the added volume within a certain range, thereby avoiding overflow of humidification liquid when the humidification tank is rotated to different angles.

[0130] Specifically, a connecting rib is further provided on the side of the sealing rib position 16, which connects the sealing rib position 16 to the air outlet end wall. There is a gap between the connecting rib and the side wall to form a liquid storage space. This arrangement can control the maximum volume of liquid added to ensure that the liquid will not flow out from the first air outlet 221 or the second air inlet 321 when rotating at any angle.

[0131] Further, see Figure 3 , Figure 5 and Figure 7 The seal 4 includes a connecting plate 41 and a sealing plate 42 which are connected to each other, and an elastic member 44 is sleeved on the end of the sealing plate 42; the seal 4 also includes a locking plate 43 connected to the sealing plate 42, one end of the locking plate 43 forms a force-bearing part, and the other end forms a locking part for buckling the shell 1.

[0132] It can be understood that the end of the connecting plate 41 away from the sealing plate 42 is hinged to the shell 1, so that the end of the connecting plate 41 away from the sealing plate 42 forms a connecting end, and the end of the sealing plate 42 away from the connecting plate 41 forms a movable end. The shell 1 is provided with a locking groove, and the locking part can be engaged with the locking groove to achieve locking of the seal 4. The sealing plate 42 and the locking plate 43 are connected by an elastic arm 431, and the elastic arm 431 is located in the middle of the length direction of the locking plate 43, so that when the force-bearing part is pressed toward the direction close to the sealing plate 42, the locking plate 43 applies a force to the elastic arm 431, so that the elastic arm 431 is deformed, and the locking part moves toward the direction away from the sealing plate 42 to achieve the release of the locking part and the shell 1. After the pressure on the force-bearing part is cancelled, the elastic arm 431 recovers its deformation, so that the locking part returns to the initial position.

[0133] When opening the drain port 15, the force-bearing portion is pressed toward the direction of the sealing plate 42 to rotate the locking plate 43, and then the locking portion moves in a direction away from the sealing plate 42, so that the locking portion is released from the snapping with the shell 1, and then pressure is applied to the connecting plate 41 away from the drain port 15, so that the connecting plate 41 drives the sealing plate 42 and the locking plate 43 to rotate, and finally the elastic member 44 is separated from the drain port 15 to complete the opening of the drain port 15.

[0134] By setting the locking plate 43, on the one hand, the connection stability between the seal 4 and the shell 1 is increased when the drain port 15 is sealed, so as to ensure the sealing effect of the drain port 15. On the other hand, it is easy to release the locking part from the shell 1, so as to facilitate the opening of the drain port 15.

[0135] In addition, since the elastic member 44 is sleeved on the end of the sealing plate 42 , the sealing plate 42 can support the elastic member 44 , thereby increasing the sealing effect of the elastic member 44 on the liquid discharge port 15 .

[0136] Preferably, the inner wall of the elastic member 44 is provided with a snap-in groove, and the sealing plate 42 is provided with a snap-in block corresponding to the snap-in groove. After the elastic member 44 is sleeved on the sealing plate 42, the snap-in block is snapped into the snap-in groove to increase the connection stability between the elastic member 44 and the sealing plate 42.

[0137] The present application does not specifically limit the structure of the elastic member 44. Preferably, the elastic member 44 is a sleeve structure made of silicone material to increase the sealing effect of the elastic member 44 on the drain port 15. In other embodiments, the elastic member 44 can also be a structure made of other materials.

[0138] Further, see Figure 3 and Figure 5 A guide rib 131 is provided in the liquid storage cavity 13 , and the guide rib 131 forms a guide slope, and the guide slope is used to guide the liquid to the discharge port 15 .

[0139] When discharging the liquid in the liquid storage chamber 13, the shell 1 is rotated so that the discharge port 15 is located at the lowest point of the shell 1, and then the liquid in the liquid storage chamber 13 is completely discharged through the discharge port 15 under the guidance of the guide slope, so as to further avoid the occurrence of liquid residue in the liquid storage chamber 13, thereby further improving the user experience.

[0140] The present application does not specifically limit the formation method of the guide rib 131. Preferably, refer to Figure 3 and Figure 5 The guide rib 131 is formed by thickening the wall of the housing 1 corresponding to the drain port 15, so as to reduce the production difficulty and production cost of the humidification tank; and it can also reduce the influence on the structural strength of the housing 1 caused by the need to set the locking groove on the housing 1. In other embodiments, the guide rib 131 can also be formed by a block structure provided in the liquid storage chamber 13.

[0141] In this embodiment, the liquid discharge port 15 and the second air outlet 311 are located on the same side of the housing 1 so that the seal 4 and the ventilator are avoided, thereby achieving the effect of facilitating the connection of the humidifier tank and the ventilator.

[0142] Implementation method 2. In this implementation method, refer to Figure 6 and Figure 8 The sealing member 4 is a flexible sealing plug, which increases the sealing effect of the sealing member 4 on the liquid discharge port 15, so that when opening or sealing the liquid discharge port 15, it is only necessary to pull or press the flexible sealing plug, thereby achieving the effect of facilitating the sealing or opening of the liquid discharge port 15; at the same time, the structure of the sealing member 4 is simplified and the production cost of the sealing member 4 is reduced, thereby reducing the production cost of the humidification tank; in addition, there is no need to make an avoidance design for the corresponding flexible sealing plug on the shell 1, so as to further increase the maximum amount of liquid that can be accommodated in the liquid storage chamber 13.

[0143] Preferably, the flexible sealing plug has a sealing column that can be interference fit with the drain port 15 and a flexible sheet located outside the shell 1. The shell 1 is provided with a connecting column, and the flexible sheet is passed through the connecting column. Then, after the sealing column is separated from the drain port 15, the flexible sealing plug is connected to the shell 1 through the flexible sheet and the connecting column, so as to avoid the flexible sealing plug from being easily lost, thereby further improving the user experience.

[0144] In this embodiment, the drain opening and the first air inlet 211 are located on the same side of the shell 1, so that after the humidification tank is connected to the ventilator, the ventilator can block the flexible sealing plug to increase the connection stability between the flexible sealing plug and the drain port 15, thereby ensuring the sealing effect of the drain port 15.

[0145] In a preferred embodiment, the housing 1 is provided with a maximum liquid level line. When the height of the liquid reaches the maximum liquid level line, the volume of the liquid accounts for at most one third of the total volume of the liquid storage chamber 13 .

[0146] Preferably, when the height of the liquid reaches the maximum liquid level line, the volume of the liquid accounts for one quarter of the total volume of the liquid storage chamber 13 .

[0147] Since the shell 1 is provided with a maximum liquid level line, when liquid is added to the liquid storage chamber 13, the maximum liquid level line can serve as a reference for the user, so as to facilitate the user to add an appropriate amount of liquid into the liquid storage chamber 13; at the same time, it also avoids the situation where the user adds too much liquid into the liquid storage chamber 13, causing the liquid to enter the inlet and outlet air channels, so as to ensure the service life of the ventilator and increase the user's experience.

[0148] By controlling the ratio of the volume of the liquid to the total volume of the liquid storage chamber 13 when the height of the liquid reaches the maximum liquid level line, it can be ensured that when the humidification tank is rotated to various angles, the liquid level height is lower than the height of the first air outlet 221 and the second air inlet 321, so as to prevent the liquid from flowing out through the first air outlet 221 or the second air inlet 321.

[0149] It should be noted that there are two ways to add liquid to the liquid storage chamber 13, one of which is to keep the first air inlet 211 in a vertically upward state, so as to add liquid to the liquid storage chamber 13 by adding liquid into the first air inlet 211; the other is to keep the second air outlet 311 in a vertically upward state, so as to add liquid to the liquid storage chamber 13 by adding liquid into the second air outlet 311; and the maximum liquid level line in the present application can be set with two groups for the two methods of adding liquid, so that the user has a reference when adding water to the liquid storage chamber 13 by any method, or a group of maximum liquid level lines is set corresponding to any method.

[0150] In a preferred embodiment, referring to Figure 7 and Figure 8 The shell body 1 includes a lower shell 11 and an upper cover 12 arranged on the lower shell 11. The lower shell 11 has a through hole for the air outlet pipeline 3 to pass through. The air outlet pipeline 3 is provided with a connecting plate 33 that abuts against the through hole. The connecting plate 33 is located inside the lower shell 11. The air inlet pipeline 2 is integrally formed with the upper cover 12. After the upper cover 12 is connected to the lower shell 11, the air inlet pipeline 2 applies pressure toward the through hole to the air outlet pipeline 3, so that the connecting plate 33 is pressed against the lower shell 11 under the action of the air outlet pipeline 3, thereby realizing the extrusion and fixation of the air outlet pipeline 3, thereby reducing the production difficulty and production cost of the humidification tank.

[0151] The present application does not specifically limit the material of the humidification tank. Preferably, the humidification tank is made of a transparent material, such as an acrylic material or a transparent PET material, so that the user can observe the amount of liquid in the liquid storage chamber 13 at any time. In other embodiments, the humidification tank can also be made of other non-transparent materials.

[0152] Anything not described in this application can be achieved by adopting or drawing on existing technologies.

[0153] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0154] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
