Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0033] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0034] This embodiment provides a ventilator.

[0035] Please refer to Figure 1-7 The ventilator includes a host 1000 and a humidifier device 2000.

[0036] Please refer to Figure 1-3The host 1000 is used to pressurize the gas to generate positive pressure gas. The humidifier device 2000 includes a humidification tank 2100 and a ventilation tube assembly 2200. The humidification tank 2100 has a through hole 2120. The through hole 2120 on the humidification tank 2100 and the ventilation tube assembly 2200 are connected to the host 1000.

[0037] On the other hand, this embodiment also provides a humidifier device 2000 .

[0038] Please refer to Figure 2-5 The humidifier device 2000 includes a humidification tank 2100 and a ventilation tube assembly 2200 .

[0039] The humidification tank 2100 has a through hole 2120, which is used to communicate with the main unit 1000 of the ventilator, and the humidification tank 2100 is used to store liquid. The ventilation pipe assembly 2200 includes a ventilation pipe 2210 and a first mounting portion 2220, one end of the ventilation pipe 2210 is connected to the through hole 2120, and the other end extends into the humidification tank 2100. The ventilation pipe 2210 is connected to the first mounting portion 2220, and the humidification tank 2100 has a second mounting portion 2110, and the first mounting portion 2220 is detachably connected to the second mounting portion 2110.

[0040] Since the first mounting part 2220 and the second mounting part 2110 are detachably connected, when the humidifier tank 2100 needs to be cleaned, the first mounting part 2220 and the second mounting part 2110 can be disassembled, and then the ventilation tube assembly 2200 and the humidifier tank 2100 can be separated to clean the dead corner formed between the ventilation tube assembly 2200 and the humidifier tank 2100, thereby reducing the possibility of breeding bacteria due to incomplete cleaning of the humidifier tank 2100, thereby helping to improve the safety of the ventilator.

[0041] Please refer to Figure 2-4 In one embodiment, the first mounting portion 2220 is a snap-fit ​​structure, and the second mounting portion 2110 is a buckle structure, and the snap-fit ​​structure can be engaged with and disengaged from the buckle structure.

[0042] The user can conveniently engage the buckle structure with the buckle position structure to fix the ventilation tube assembly 2200 on the humidification tank 2100, and can also disengage the buckle structure from the buckle position structure to remove the ventilation tube assembly 2200 from the humidification tank 2100. Specifically, the buckle structure can be in the shape of a column, a plate, a strip, or any other suitable shape, and the buckle position structure can be a matching gap, a matching groove, etc.

[0043] Please refer to Figure 2-4In one embodiment, the buckle structure includes two oppositely disposed clamping blocks 2111, a gap is formed between the two clamping blocks 2111, and the buckle structure includes a clamping plate 2221 and a placement plate 2222, the clamping plate 2221 is connected to the middle of the placement plate 2222, and the clamping plate 2221 has an arc surface on the side facing the gap. When the buckle structure is engaged with the buckle structure, the clamping plate 2221 is interference fit with the gap, and the placement plate 2222 is placed on the clamping block 2111. When the buckle structure is released from the buckle structure, the clamping plate 2221 is out of the gap.

[0044] When installing the vent assembly 2200, the user embeds the clamping plate 2221 into the gap between the two clamping blocks 2111, and places the placement plate 2222 on the clamping block 2111. Since the clamping plate 2221 and the gap are interference fit, the vent assembly 2200 is fixed in the humidification tank 2100. When disassembling the vent assembly 2200, the user removes the clamping plate 2221 from the gap between the two clamping blocks 2111, and then disassembles the vent assembly 2200 from the humidification tank 2100. The installation and disassembly process is simple and quick, which is conducive to improving the disassembly and assembly efficiency of the user.

[0045] Please refer to Figure 2-4 , 7 and 8, in one embodiment, the arc surface of the clamping plate 2221 has a protruding structure 2223, and the buckle structure further includes a mounting wall 2112, and the two clamping blocks 2111 are connected to the mounting wall 2112. When the clamping plate 2221 is engaged with the gap between the two clamping blocks 2111, the protruding structure 2223 abuts against the edge of the mounting wall 2112 to prevent the clamping plate 2221 from escaping from the gap, so that the fitting between the clamping plate 2221 and the gap is more stable, thereby making the installation of the ventilation tube assembly 2200 in the humidification tank 2100 more stable.

[0046] Please refer to Figure 2 , 3 , 7 and 8, in one embodiment, one end of the vent pipe 2210 is sealed and connected to the through hole 2120 via a sealing ring 2230. The sealing between the vent pipe 2210 and the through hole 2120 is improved, which helps to prevent gas and liquid from leaking from the connection between the vent pipe 2210 and the through hole 2120.

[0047] Please refer to Figure 2-4 In one embodiment, the ventilation tube assembly 2200 further includes a stopper 2240 , which is disposed around the outer periphery of the ventilation tube 2210 . When the ventilation tube 2210 is docked with the through hole 2120 , the stopper 2240 abuts against the inner wall of the humidification tank 2100 .

[0048] On the one hand, when the vent pipe 2210 is docked with the through hole 2120, the stopper 2240 conflicts with the inner wall of the humidification tank 2100, which can prevent the vent pipe 2210 from moving in the vent hole, and plays a role in positioning and confirming that the assembly is in place. On the other hand, when installing the vent pipe assembly 2200, the stopper 2240 can play an auxiliary role in the operation of the buckle structure and the buckle structure engaging. Specifically, the vent pipe 2210 is first docked with the vent hole, and the stopper 2240 is made to conflict with the inner wall of the humidification tank 2100 to achieve positioning of one end of the vent pipe assembly 2200, and then the buckle structure is engaged with the buckle structure to achieve the fixation of the other end of the vent pipe assembly 2200.

[0049] Please refer to Figure 2-4 , 7 and 8, in one embodiment, the vent assembly 2200 further includes a stopper 2240, which is arranged around the outer periphery of the vent 2210. When the vent 2210 is docked with the through hole 2120, the stopper 2240 abuts against the inner wall of the humidification tank 2100. A groove 2241 is provided on the side of the stopper 2240 abutting against the inner wall of the humidification tank 2100, and the sealing ring 2230 is installed in the groove 2241, and at least a part of the sealing ring 2230 extends out of the groove 2241 to seal the gap between the stopper 2240 and the inner wall of the humidification tank 2100.

[0050] The stopper 2240 can be in contact with the inner wall of the humidification tank 2100 around the vent pipe 2210, which is conducive to improving the positioning effect of the stopper 2240 on the vent pipe 2210 and improving the stability of the vent pipe assembly 2200 installed in the humidification tank 2100. The sealing ring 2230 is stably installed on the stopper 2240 through the embedded groove 2241, thereby improving the sealing performance between the stopper 2240 and the inner wall of the humidification tank 2100. Specifically, in the present embodiment, the stopper 2240 is a plate-like structure, that is, the stopper 2240 is a stopper plate. In other embodiments, the stopper 2240 can also be a block structure, a strip structure or a structure of other suitable shapes.

[0051] Please refer to Figure 2-4 In one embodiment, the through hole 2120 includes an air inlet hole 2121 and an air outlet hole 2122, and the vent pipe 2210 includes an air inlet pipe 2211 and an air outlet pipe 2212. The air inlet pipe 2211 and the air outlet pipe 2212 both have an inlet end and an outlet end. The inlet end of the air inlet pipe 2211 is connected to the air inlet hole 2121, and the outlet end of the air inlet pipe 2211 extends into the humidification tank 2100. The outlet end of the air outlet pipe 2212 is connected to the air outlet hole 2122, and the inlet end of the air outlet pipe 2212 extends into the humidification tank 2100.

[0052] When the ventilator is working, the positive pressure gas generated by the host 1000 enters the humidification tank 2100 through the air inlet 2121 and the inlet and outlet ends of the air inlet pipe 2211 for humidification, and the humidified gas is discharged from the humidification tank through the inlet and outlet ends of the air outlet pipe 2212 and the air outlet 2122.

[0053] Please refer to Figure 2-5 In one embodiment, the air inlet pipe 2211 and the air outlet pipe 2212 are arranged side by side, and the air inlet pipe 2211 includes a first section 22111 close to the inlet end of the air inlet pipe 2211 and a second section 22112 close to the outlet end of the air inlet pipe 2211, and the outlet end of the air inlet pipe 2211 is inclined toward the bottom of the humidification tank 2100 from the side opposite to the air outlet pipe 2212, and the axis line of the second section 22112 forms an acute angle with the normal line of the bottom of the humidification tank 2100.

[0054] On the one hand, the airflow entering the humidification tank 2100 from the air inlet pipe 2211 needs to flow from one side of the humidification tank 2100 to the other side before it can be discharged from the air outlet pipe 2212, which prolongs the retention time of the airflow in the humidification tank 2100, so that the airflow takes away more water vapor and discharges from the air outlet pipe 2212, which is conducive to improving the humidification effect. On the other hand, the direction and angle design of the second section 22112 of the air outlet pipe 2212 make it possible for the water vapor in the humidification tank 2100 to encounter the cold air inlet pipe 2211, and the water droplets formed by the condensation of the water vapor can flow back into the humidification tank 2100 along the outlet end of the air inlet pipe 2211 obliquely downward, so as to prevent the water droplets from flowing back from the air inlet pipe 2211 into the body connected to the inlet end of the air inlet pipe 2211.

[0055] Please refer to Figure 6 In another embodiment, the air inlet pipe 2211 and the air outlet pipe 2212 are arranged side by side, and the air inlet pipe 2211 includes a first section 22111 close to the inlet end of the air inlet pipe 2211 and a second section 22112 close to the outlet end of the air inlet pipe 2211, and the axis line of the second section 22112 is parallel to the normal line of the bottom of the humidification tank 2100.

[0056] Since the second section 22112 of the outlet pipe 2212 is vertically toward the bottom of the humidification tank 2100, when the water vapor in the humidification tank 2100 encounters the cold air inlet pipe 2211, water droplets formed by condensation of the water vapor can flow back into the humidification tank 2100 along the vertically downward outlet end of the air inlet pipe 2211, thereby preventing the water droplets from flowing back from the air inlet pipe 2211 into the body connected to the inlet end of the air inlet pipe 2211.

[0057] Please refer to Figure 3 , 7 and 8. In one embodiment, the first section 22111 of the air inlet pipe 2211 and the air outlet pipe 2212 are inclined toward the top of the humidification tank 2100.

[0058] The height of the end of the first section 22111 away from the air inlet 2121 and the height of the end of the air outlet pipe 2212 away from the air outlet 2122 are increased, which prolongs the movement path of the airflow in the humidification tank 2100, and further prolongs the residence time of the airflow in the humidification tank 2100, so that the airflow can carry away more water vapor and discharge it from the air outlet pipe 2212, which is beneficial to improving the humidification effect.

[0059] Please refer to Figure 6 In one embodiment, the second section 22112 includes a reflux portion 22113 disposed opposite to the outlet end of the intake pipe 2211 , and the first section 22111 is connected between the reflux portion 22113 and the outlet end of the intake pipe 2211 .

[0060] Since the reflux portion 22113 is added and the first section 22111 is connected between the reflux portion 22113 and the outlet end of the air inlet pipe 2211, when the water vapor in the humidification tank 2100 encounters the cold air inlet pipe 2211, it can be liquefied into water droplets in the reflux portion 22113, and slide down from the reflux portion 22113 along the second section 22112 of the air inlet pipe 2211 under the action of gravity back into the humidification tank 2100. If the first section 22111 of the air inlet pipe 2211 is connected to the top of the second section 22112, the water droplets may flow into the body along the inner wall of the first section 22111.

[0061] Please refer to Figure 2 , 3 , 7 and 8, in one embodiment, the humidification tank 2100 includes a tank body 2130 and a cover body 2140 covered on the tank body 2130, and the second mounting portion 2110 is disposed on the tank body 2130 or the cover body 2140. When cleaning, changing water, etc. are required, the user can open the cover body 2140 for operation. Optionally, the cover body 2140 can be detachably connected or movably connected to the tank body 2130, for example, the cover body 2140 can be rotatably connected to the tank body 2130, and the cover body 2140 can be rotated relative to the tank body 2130 to achieve opening and closing.

[0062] The second mounting portion 2110 and the through hole 2120 may be disposed on the cover 2140 or the tank 2130. For example, in this embodiment, the vent assembly 2200 may be mounted on the tank 2130, the through hole 2120 is located in the middle of the tank 2130, and the second mounting portion 2110 is located on the side of the tank 2130 opposite to the vent hole. In another embodiment, the vent assembly 2200 may also be mounted on the cover 2140, the through hole 2120 is located in the middle of the cover 2140, and the second mounting portion 2110 is located on the top of the cover 2140.

[0063] Please note that, please refer to Figure 2 and 3 The side of the humidification tank 2100 where the cover 2140 is located is the top of the humidification tank 2100 , the side opposite to the cover 2140 is the bottom of the humidification tank 2100 , and the part between the cover 2140 and the bottom of the humidification tank 2100 is the middle part of the humidification tank 2100 .

[0064] Please refer to Figure 2 and 3 In another embodiment, the vent assembly 2200 is disposed in the middle of the humidification tank 2100. When the humidification tank 2100 is accidentally overturned or inverted, the liquid in the humidification tank 2100 is prevented from flowing back into the air inlet pipe 2211 and the air outlet pipe 2212, thereby achieving 360° backflow prevention.

[0065] Please refer to Figure 2 and 3 In another embodiment, the vent assembly 2200 is integrally formed, which reduces the production cost of the vent assembly 2200 and improves the production efficiency of the vent assembly 2200. Specifically, the vent assembly 2200 can be integrally formed by injection molding.

[0066] The above specific examples are used to illustrate the present invention, which is only used to help understand the present invention and is not intended to limit the present invention. For those skilled in the art, according to the concept of the present invention, some simple deductions, modifications or substitutions can be made.
