[0018] Due to the adoption of the above technical scheme, the utility model has obtained the beneficial effects as follows:

[0019] 1. In the utility model, the gas outlet is arranged on the top wall of the shell, so that the gas inlet and the gas outlet are respectively arranged on two different sides of the shell, the side where the gas inlet is located is not blocked by the host computer after being connected with the host computer, so that the gas outlet can be directly connected with the pipeline of the user end.

[0020] The outer wall of the shell is provided with a locking piece capable of elastically moving relative to the shell, so that after the plug-in section of the humidifying device is plugged into the main machine in the first direction, the locking piece can be locked with the shell, and the stop force generated between the locking piece and the main machine can prevent the humidifying device from moving relative to the main machine, thereby avoiding the humidifying device from being loosened from the main machine, and ensuring the stability and sealing of the structural connection and air path connection.

[0021] 2. As a preferred embodiment of the present utility model, the locking piece has a connecting end connected to the shell, and a free end extending in the first direction, and the free end has a clearance gap with the shell to enable the free end to swing around the connecting end, and the free end is provided with a clamping hook. The locking piece extends in the first direction, and the extension direction is consistent with the plug-in direction of the humidifying device, thereby improving the smoothness during the plugging of the humidifying device, and avoiding the interference between the locking piece and the inner wall of the main machine plug-in seat during plugging to generate a jamming feeling. When the humidifying device is plugged in place, the clamping hook of the free end is clamped with the fixed structure of the main machine to realize the locking of the humidifying device. Moreover, since the locking piece has a structure of one end fixed and one end free, when the locking piece is abutted, the free end can swing around the connecting end to elastically move and be clamped with or unlocked from the fixed structure on the main machine, and the existence of the clearance gap also provides space for the swinging of the locking piece, thereby ensuring that the locking piece has sufficient movement amplitude to be disengaged from the fixed structure of the main machine and reducing the unlocking difficulty.

[0022] 3. As a preferred embodiment of the present utility model, the upper cover is also floatingly installed with an unlocking piece, and the locking piece is arranged on the unlocking piece, and the unlocking piece can drive the floating movement of the locking piece to disengage the locking piece from the main machine of the breathing machine.

[0024] 5. As a preferred embodiment of the utility model, the locking member is fixed to the side wall of the raised portion to have a clearance with the body, and the body is further provided with a protective protruding rib protruding upward, the protective protruding rib is located on both sides of the locking member, and the upper edge of the protective protruding rib is not higher than the upper edge of the locking member. The locking member is fixed to the side wall of the raised portion to form a clearance between the lower side of the locking member and the body, and the locking member can swing up and down. Since the locking member is arranged on the raised portion, it protrudes from the outer surface of the shell, and when the humidification device is removed from the main machine, the protruding locking member is easy to collide with other components, thereby there is a risk of deformation or breakage of the locking member.

[0049] As shown in Figure 1 , Figure 8 , Figure 10 , Figure 11 , Figure 12 A humidifying device for breathing machine, including shell 1, shell 1 has the plug-in segment 16 that can be along the first direction and the main machine 5 of breathing machine plug-in cooperation, the side wall of shell 1 is provided with air inlet 13, the top wall of shell 1 is provided with air outlet 14, the outer wall of shell 1 is further provided with locking piece 2, locking piece 2 can be elastically moved relative to shell 1 to lock or unlock with the main machine 5 of breathing machine.

[0050] The utility model discloses, gas outlet 14 is established at the top wall of shell 1, makes that air inlet 13 and gas outlet 14 are distributed respectively in two different sides of shell 1, makes that the side of air inlet 13 is butt jointed after main machine 5, gas outlet 14 will not be shaded by main machine 5, thereby more convenient with the pipeline of user end is connected directly with gas outlet 14.

[0051] The outer wall of the shell 1 is provided with a locking piece 2, which can elastically move relative to the shell 1, so that after the plug-in section 16 of the humidifying device is plugged in the first direction with the main machine 5, the locking piece 2 can be locked with the shell 1. By using the stopping force generated between the locking piece 2 and the main machine 5, the movement of the humidifying device relative to the main machine 5 is prevented, thereby avoiding the loosening of the humidifying device and the main machine 5, and ensuring the stability and sealing of the structural connection and air connection between the two. In addition, when the humidifying device needs to be disassembled, the locking piece 2 only needs to be elastically moved, and the locking piece 2 can be disengaged with the main machine 5. At this time, the humidifying device can be pulled out of the main machine 5 in the direction opposite to the first direction. In this way, the humidifying device not only maintains the simple installation mode of plugging, but also improves the connection stability with the main machine 5 through the locking piece 2. At the same time, the switching of the locking or unlocking state of the locking piece 2 is also relatively simple and easy to operate, thereby improving the connection effect of the humidifying device and the main machine 5 as a whole and improving the use experience.

[0052] It should be noted that the utility model does not limit the movement mode of the locking piece 2. Preferably, as shown in Figure 3 、 Figure 12 The locking piece 2 has a connecting end 21 connected to the shell 1 and a free end extending in the first direction. The free end has a clearance gap with the shell 1, so that the free end can swing around the connecting end 21. The free end is provided with a clamping hook 22.

[0053] The locking piece 2 extends in the first direction, which is consistent with the plug-in direction of the humidifying device, thereby improving the smoothness during the plugging process of the humidifying device and avoiding the interference between the locking piece 2 and the inner wall of the main machine 5 plug-in seat 51 during plugging, thereby avoiding the jamming feeling. When the humidifying device is plugged in place, the clamping hook 22 of the free end is clamped with the fixed structure 53 of the main machine 5, thereby realizing the locking of the humidifying device. In addition, since the locking piece 2 has a structure of one end fixed and one end free, when the locking piece 2 is abutted, the free end can swing around the connecting end 21, thereby elastically moving and clamping or unlocking with the fixed structure 53 on the main machine 5. At the same time, the existence of the clearance gap also provides space for the swinging of the locking piece 2, thereby ensuring that the locking piece 2 has sufficient movement amplitude to be disengaged with the fixed structure 53 of the main machine 5, thereby reducing the unlocking difficulty.

[0054] Specifically, the host 5 can be provided with a matching hook corresponding to the clamping hook 22, or a matching slot, to complete clamping with the clamping hook 22, which is not limited here.

[0055] Of course, in other embodiments, the locking member 2 can also be elastically connected with the shell 1, so that the locking member 2 can move relative to the shell 1 under the elastic force of the elastic member, or the locking member 2 can be slidingly connected with the shell 1, so that the locking member 2 can slide relative to the shell 1 to achieve locking or unlocking with the host 5.

[0056] It should be noted that the present application does not limit the way the locking member 2 is driven to move, which can be one of the following embodiments:

[0057] Embodiment one: In this embodiment, the locking member 2 can be automatically moved by abutting during the process of inserting the humidification device in the first direction and removing it in the direction opposite to the first direction, and then completing unlocking with the host 5. That is, taking the process of removing the humidification device as an example, the user only needs to apply a force opposite to the first direction to the humidification device, and the locking member 2 can be abutted by the unlocking structure on the host 5 to elastically move, thereby completing the release with the fixed structure 53 on the host 5.

[0058] Preferably, as shown in Figure 8 , Figure 9 , Figure 12 The clamping hook 22 and / or the fixed structure 53 of the host 5 are provided with a guide transition surface, which can be a slope or a circular arc surface or other irregular curved surface. During the process of inserting the humidification device in the first direction and removing it in the direction opposite to the first direction, the clamping hook 22 can contact the fixed structure 53 through the guide transition surface, thereby generating a force perpendicular to the first direction, so that the free end elastically moves to complete clamping with the fixed structure 53, or to release the clamping with the fixed structure 53.

[0059] Further, the shell 1 includes a tank body 11 with a water inlet 111 and an upper cover 12 capable of covering the water inlet 111, and the locking member 2 is located on the upper cover 12. Of course, as shown in Figure 8 The locking member 2 can also be provided on the tank body 11.

[0060] The locking member 2 is arranged on the upper cover 12. On one hand, the unlocking member 3 can be removed from the tank body 11 together with the upper cover 12, so that when the locking member 2 is damaged, the upper cover 12 can be replaced and repaired as an independent unit without replacing the tank body 11, thereby reducing the maintenance cost. On the other hand, the locking member 2 can be used as a foolproof design of the upper cover 12. When the user does not install the upper cover 12 on the tank body 11 or the upper cover 12 is not installed in place, the locking member 2 does not exist or is not in the correct position, and thus cannot normally complete the clamping with the fixing structure 53 of the host 5. Only when the upper cover 12 is installed in place, the locking member 2 can normally lock with the host 5.

[0061] Preferably, as shown in Figure 1 , Figure 8 , Figure 10 , the top wall of the shell 1 includes a body and a raised portion 19 raised upward relative to the body, and the locking member 2 is fixed to the raised portion 19.

[0062] The arrangement of the raised portion 19 reduces the gap between the shell 1 and the inner wall of the plug-in socket 51 of the host 5, makes the plug-in of the humidifying device and the host 5 more compact, and reduces the shaking of the humidifying device inside the host 5. At the same time, the raised portion 19 is closer to the inner wall of the plug-in socket 51, so the locking member 2 is also easier to complete the cooperation with the fixing structure 53 of the inner wall, and after clamping, it can also reduce the assembly gap between the locking member 2 and the fixing structure 53, thereby reducing the shaking of the humidifying device.

[0063] Further, as shown in Figure 8 , Figure 9 , the locking member 2 is fixed to the side wall of the raised portion 19 to have a clearance between the locking member 2 and the body, and the body is further provided with a protective protruding rib 23 protruding upward, the protective protruding rib 23 is located on both sides of the locking member 2, and the upper edge of the protective protruding rib 23 is not higher than the upper edge of the locking member 2.

[0064] The locking member 2 is fixed to the side wall of the raised portion 19 to form a clearance between the lower side of the locking member 2 and the body, and the locking member 2 can swing up and down. Since the locking member 2 is arranged on the raised portion 19, it protrudes from the outer surface of the shell 1, and when the humidifying device is removed from the host 5, the protruding locking member 2 is easy to collide with other components, thereby there is a risk of deformation or breakage of the locking member 2. By arranging the protective protruding rib 23 on the body, the protective protruding rib 23 is located on both sides of the locking member 2, so that the protective protruding rib 23 can protect the locking member 2, so that foreign objects cannot directly contact the locking member 2, and at the same time, the upper edge of the protective protruding rib 23 is not higher than the upper edge of the locking member 2, which also ensures that the clamping hook 22 of the locking member 2 can directly contact the host 5 to complete the clamping cooperation.

[0065] Specifically, as shown in Figure 8 , Figure 9As shown, a deformation cavity is formed between the protective ribs 23 on both sides, and the locking member 2 can move into the deformation cavity. At the same time, the free end of the locking member 2 is provided with an upward protruding hook 22. The upper edge of the protective rib 23 is flush with or lower than the top of the hook 22, so that the hook 22 can cooperate normally with the fixing structure 53 on the host 5.

[0066] Implementation Method 2: In this implementation method, when disassembling the humidification device, the user can manually drive the locking member 2 to elastically move and unlock it from the main unit 5. That is, the user needs to apply a force to the locking member 2 to make it elastically move, and at the same time apply a force opposite to the first direction to the humidification device to pull the humidification device away from the main unit 5.

[0067] Specifically, such as Figures 3 to 7 As shown, the upper cover 12 is also floatingly mounted with an unlocking component 3, and a locking component 2 is set on the unlocking component 3. The unlocking component 3 can drive the locking component 2 to float and disengage the locking component 2 from the main unit 5 of the ventilator.

[0068] The locking element 2 is set on the unlocking element 3, so it can float with the floating of the unlocking element 3, allowing the user to unlock the locking element 2 from the main unit 5 by actively operating the unlocking element 3. When disassembling the humidification device, the user presses the unlocking element 3 and pulls the humidification device in the opposite direction to the first direction, thereby pulling it off the main unit 5. Since the locking element 2 and the main unit 5 have completed the avoidance unlocking while the unlocking element 3 is pressed, the pulling process is smoother and less strenuous.

[0069] It should be noted that, in this embodiment, when installing the humidification device along the first direction, the user can press the unlocking member 3 to allow the locking member 2 to avoid contact with the fixing structure 53 of the main unit 5, and then release the unlocking member 3 after insertion to allow the locking member 2 to spring back and reposition itself to complete the engagement with the fixing structure 53. Alternatively, the unlocking member 3 can be left unpressed during insertion, and the engagement can be automatically completed by the abutting force between the locking member 2 and the fixing structure 53.

[0070] In this embodiment, although the setting of the unlocking component 3 allows the user to directly control the unlocking component 3 to achieve movement control of the locking component 2, making unlocking more effortless, this embodiment does not limit the user's operation method. The above is only an example of one operation method. For example, in another embodiment, the latch hook 22 and the fixing structure 53 of the host 5 can also be provided with a guide transition surface, so that even if the user does not press the unlocking component 3, the locking component 2 can still undergo elastic movement under the squeezing force of the fixing structure 53 during the process of inserting the humidifying device along the first direction and removing the humidifying device in the opposite direction.

[0071] The connection mode of the unlocking member 3 and the upper cover 12 is not limited in the embodiment, and in an embodiment, an elastic member is arranged between the unlocking member 3 and the upper cover 12, which can be a spring, a silica gel member or other elastic component, so as to enable the unlocking member 3 to float under the elastic force of the elastic member.

[0072] In another embodiment, as shown in Figures 5 to 7 , the unlocking member 3 comprises an operation panel 31 and an elastic rib position 32 located below the operation panel 31, the elastic rib position 32 has a fixed end fixed with the operation panel 31 and a swing end extending obliquely towards the locking member 2, the swing end can swing around the fixed end to make the operation panel 31 float up and down.

[0073] Specifically, as shown in Figure 6 , Figure 7 , the locking member 2 is located at one end of the operation panel 31, and the swing end of the elastic rib position 32 extends obliquely towards the end where the locking member 2 is located, so that when the user presses the operation panel 31, the end where the locking member 2 is located will float down, thereby making the locking member 2 disengage from the host 5 and completing the unlocking.

[0074] Further, as shown in Figure 5 , Figure 6 , Figure 7 , the upper cover 12 is provided with a mounting sink 121, the mounting sink 121 is provided with a positioning protrusion 123, the swing end of the elastic rib position 32 is provided with a positioning opening 321 matched with the positioning protrusion 123, and the mounting sink 121 is further provided with a guide sliding groove 122 located on both sides of the elastic rib position 32, which can be matched with both ends of the elastic rib position 32 to guide the installation of the unlocking member 3.
