DETAILED DESCRIPTION

[0039] The specific embodiments of the present application will be described in detail below with reference to the drawings. It should be understood that the specific embodiments described herein are merely illustrative and explanatory and are not intended to limit the present application.

[0040] In the present application, the orientation words such as "up, down, front, back, left, right" refer to the orientation shown in the drawings unless otherwise specified. Figure 1 "Inner, outer" refers to the inner and outer relative to the outline of each component.

[0041] The water tank mounting structure of the present application provides a water tank mounting structure, which comprises a water tank 10, a mounting space 21, and a connecting structure. The water tank 10 is arranged to be mounted and dismounted from the mounting space 21 by rotating. The connecting structure is arranged to connect the water tank 10 to the mounting space 21 when the water tank 10 is rotated into the mounting space 21, and to release the connection between the water tank 10 and the mounting space 21 when the water tank 10 is dismounted from the mounting space 21.

[0042] The water tank mounting structure of the present application adopts the above technical solution, arranges the water tank 10 to be mounted and dismounted from the mounting space 21 by rotating, and arranges the connecting structure to connect the water tank 10 to the mounting space 21 when the water tank 10 is rotated into the mounting space 21, and to release the connection between the water tank 10 and the mounting space 21 when the water tank 10 is dismounted from the mounting space 21. This can ensure reliable installation of the water tank 10 in the mounting space 21 while making the dismounting of the water tank 10 more convenient. When adding water, the water tank 10 can be rotated out of the mounting space 21 for dismounting to prevent water from leaking into the mounting space 21, thereby ensuring the efficiency and safety of water addition.

[0043] The mounting space 21 can have a top opening 211 and a side opening 212 for mounting the water tank 10 into the mounting space 21. This not only facilitates flexible installation of the water tank 10, but also allows the water tank 10 to be in an exposed state after installation, facilitating water addition operation of the water tank 10.

[0044] During installation, the water tank 10 can be rotated into the mounting space 21 from the top opening 211 and the side opening 212, and the connecting structure connects the water tank 10 to the mounting space 21 at the same time. When it is necessary to add water to the water tank 10, the water tank 10 can be directly added water through the exposed water inlet provided on the top or side of the water tank 10 without being removed, or the water tank 10 can be rotated out of the mounting space 21 for dismounting and then added water. In this way, the installation of the water tank can be greatly simplified, and the water tank is convenient to add water. Moreover, the connecting structure has a wide selection range and can adopt any appropriate detachable connecting structure.

[0045] It should be noted that the water tank 10 and the installation space 21 can have any appropriate shape, and the side opening 212 can have different opening manners based on the shape of the installation space 21. For example Figures 1-11 In the illustrated embodiment, the installation space 21 and the water tank 10 are substantially square bodies, and the side opening 212 covers the front side, the rear side, and the right side of the installation space 21. In other embodiments, the side opening 212 can cover at least the right side of the installation space 21, so as to provide an installation passage for the water tank 10, and the front side and / or the rear side of the installation space 21 can also limit the water tank 10 to a certain extent.

[0046] In the present application, referring to Figure 1 , Figure 2 and Figure 5 , the water tank installation structure can further include a first bottom wall 22 and a first side wall 23 for defining the installation space 21, and the water tank 10 includes a liquid storage cavity 11 and a second bottom wall 12 and a second side wall 13 for defining the liquid storage cavity 11. When the water tank 10 is installed in the installation space 21, the second bottom wall 12 corresponds to the first bottom wall 22, and the second side wall 13 corresponds to the first side wall 23. Through the above arrangement, the support and installation of the water tank 10 can be achieved. Among them, the first bottom wall 22 is used to support the water tank 10, and the connecting structure can be arranged on the bottom walls 22 and 23 or the side walls 12 and 13, and is preferably arranged on the side walls 12 and 13.

[0047] In the above, in order to facilitate the rotational installation of the water tank 10 and achieve the connection with the installation space 21 at the same time, the first bottom wall 22 can include a downwardly recessed arc-shaped area 221, and the second bottom wall 12 forms a downwardly protruding arc-shaped area that is adapted to the arc-shaped area 221, and the connecting structure can be arranged on the second side wall 13 and the first side wall 23.

[0048] The second side wall 13 and the first side wall 23 can have shapes that are adapted to each other, for example, can both be flat or curved, or can be complementary in shape. When the second side wall 13 and the first side wall 23 are complementary in shape, for example, a plurality of protrusions and recesses are respectively formed on the second side wall 13 and the first side wall 23, the water tank 10 can be detachably installed in the installation space 21 by means of the complementary shapes of the second side wall 13 and the first side wall 23. In this case, the connecting structure includes a plurality of protrusions and recesses that are respectively formed on the second side wall 13 and the first side wall 23. When the second side wall 13 and the first side wall 23 are both flat or curved, the detachable installation can be achieved by arranging appropriate connecting components on the second side wall 13 and the first side wall 23.

[0049] Specifically, the connecting structure can include a first connecting component and a second connecting component, the first connecting component is arranged on one of the first side wall 23 and the second side wall 13, and the second connecting component is arranged on the other of the first side wall 23 and the second side wall 13.

[0050] In order to improve the stability, reliability and flexibility of the installation of the water tank 10, the first connecting component is arranged at an upper position of the first side wall 23 or the second side wall 13, and the second connecting component is arranged at an upper position of the first side wall 23 or the second side wall 13. That is, the first connecting component and the second connecting component are far away from the second bottom wall 12 and the first bottom wall 22.

[0051] In the present application, the first connecting component and the second connecting component can be any component or structure capable of realizing detachable connection. For example, the first connecting component and the second connecting component can be magnetic members capable of being adsorbed to each other.

[0052] Specifically, according to an embodiment of the present application, referring to Figures 2-6 , the first connecting component is arranged at an upper position of the first side wall 23, and the second connecting component is arranged at an upper position of the second side wall 13. The first connecting component includes a concave cavity 231 recessed outward from the inner wall of the first side wall 23 (i.e. leftward in Figure 5 ), and a clamping groove 232 arranged on the inner surface of the concave cavity 231, and the second connecting component includes a protruding block 131 protruding outward from the outer wall of the second side wall 13 (i.e. leftward in Figure 5 ), and a clamping member 134 arranged on the protruding block 131, the protruding block 131 is matched with the concave cavity 231, the clamping member 134 is matched with the clamping groove 232, the clamping member 134 is arranged to be clamped in the clamping groove 232 when the protruding block 131 is accommodated in the concave cavity 231, and the clamping member 134 is arranged to be disengaged from the clamping groove 232 when the protruding block 131 is subjected to an outward pulling force (i.e. a force for turning the water tank 10 out of the installation space 21).

[0053] In the above, the clamping member 134 can realize clamping and disengaging with the clamping groove 232 by itself deformation, for example, the clamping member 134 is a protrusion protruding on the protruding block 131. In order to improve the reliability of the cooperation between the clamping member 134 and the clamping groove 232 and prolong the service life thereof, it is preferred that the clamping member 134 is arranged to realize clamping and disengaging with the clamping groove 232 by moving.

[0054] Specifically, as Figures 2-8In the shown embodiment, the second connecting part further comprises a compression spring 135, the protrusion 131 has a cavity 132 in which the compression spring 135 and the clamping member 134 are arranged, the protrusion 131 is provided with an opening 133 which is in communication with the cavity 132, and the clamping member 134 is arranged to be at least partially extended out of the opening 133 under the abutting action of the compression spring 135 (as shown in Figure 7 Fig. 2a) and to be retracted into the cavity 132 by compressing the compression spring 135 when subjected to pressure (as shown in Figure 8 Fig. 2b). That is, the clamping member 134 has a first state of being at least partially extended out of the opening 133 and a second state of being retracted into the cavity 132, in the first state, the clamping member 134 can be clamped in the clamping groove 232, and in the second state, the clamping member 134 can form an avoidance to facilitate the protrusion 131 to enter and exit the recessed cavity 231.

[0055] In order to facilitate the protrusion 131 to enter and exit the recessed cavity 231 quickly and smoothly and further improve the convenience of disassembling the water tank 10, as shown in Figure 6 Fig. 2c, two guide inclined surfaces 233 can be arranged on the right side of the recessed cavity 231 at the upper and lower ends respectively to guide the protrusion 131 to enter and exit the recessed cavity 231.

[0056] In addition, as shown in Figure 7 Fig. 2d, preferably, the compression spring 135 is arranged in the vertical direction, the clamping member 134 is above the compression spring 135, the opening 133 is arranged at the top of the protrusion 131, and the clamping groove 232 is arranged at the top of the recessed cavity 231.

[0057] When the water tank 10 is turned into the installation space 21 and the protrusion 131 is pushed into the recessed cavity 231 during installation, the guide inclined surfaces 233 can press the clamping member 134 to move downward and retract into the cavity 132 while guiding the protrusion 131 to enter the recessed cavity 231 until the protrusion 131 is completely in the recessed cavity 231, at this time, the clamping member 134 is at least partially extended out of the opening 133 under the action of the compression spring 135 and clamped in the clamping groove 232.

[0058] In order to ensure the smooth extension and retraction of the clamping member 134 at the opening 133, preferably, the size of the opening 133 is smaller than the size of the clamping member 134, that is, the clamping member 134 cannot be completely extended out of the opening 133, and the clamping member 134 is partially extended out of the opening 133 under the abutting action of the compression spring 135.

[0059] As shown in Figure 6 and Figure 7 Fig. 2e, the clamping member 134 can be a sphere, and the clamping groove 232 can be a semispherical groove. In this case, the opening 133 is a circular hole, the diameter of the opening 133 is smaller than the diameter of the clamping member 134, and the size of the clamping groove 232 is matched with the size of the clamping member 134 which can be extended out of the opening 133.

[0060] In this invention, the connection structure may include multiple sets of compatible first and second connecting components to improve the stability and reliability of the water tank installation. Preferably, as shown below... Figure 2 As shown, the connection structure includes two sets of compatible first and second connecting components, which are arranged at intervals along the front-back direction.

[0061] In this invention, such as Figure 6 and Figure 7 As shown, by configuring the first bottom wall 22 to include a downwardly recessed arc-shaped area 221, and the second bottom wall 12 to form a downwardly protruding arc shape that matches the arc-shaped area 221, the support area for the water tank 10 can be increased, while simultaneously limiting the position of the water tank 10. That is, the second bottom wall 12 cannot move horizontally to the right relative to the arc-shaped area 221 and disengage from the installation space 21. Furthermore, when the connection structure includes two sets of matching first and second connecting components, the combination of the matching arc-shaped area 221 and the second bottom wall 12 enables a three-point fit between the water tank 10 and the installation space 21, thereby ensuring the stability of the water tank 10.

[0062] The arc-shaped area 221 can be set as a heating area. For example, the first bottom wall 22 can be formed by a heating plate, thereby achieving large-area heating of the water tank 10.

[0063] Among them, such as Figure 6 As shown, the axial direction of the arc-shaped region 221 (see...) Figure 1 The front-to-back direction shown is perpendicular to the installation direction of the water tank 10 (see [reference]). Figure 1 The left and right directions shown are the installation directions of the protrusion 131 and the cavity 231. In this case, the water tank 10 can rotate within a certain range relative to the arc-shaped area 221 around the axis of the arc-shaped area 221 to achieve rotational disassembly and assembly, and at the same time facilitate the adjustment of the angle of the water tank 10 to align the protrusion 131 and the cavity 231 when installing the water tank 10.

[0064] Reference Figure 5 When installing the water tank 10, first place the water tank 10 on the arc-shaped area 221, make the second bottom wall 12 fit against the arc-shaped area 221, then rotate it at a certain angle, and then push the water tank 10 to the left towards the first side wall 23, so that the protrusion 131 enters the concave cavity 231, and the snap-fit ​​piece 134 snaps into the snap-fit ​​groove 232, thus completing the installation of the water tank 10. When removing the water tank 10, you can directly grasp the water tank 10 and pull it to the right. Under the squeezing action on the right side of the snap-fit ​​groove 232, the snap-fit ​​piece 134 moves downward and retracts into the cavity 132, and the protrusion 131 disengages from the concave cavity 231, thus removing the water tank 10.

[0065] In this invention, such as Figure 7 and Figure 11As shown, the water tank 10 can include a second air inlet pipe 14 and a second air outlet pipe 15, the second air inlet pipe 14 is coaxially inserted into the second air outlet pipe 15 and has a radial spacing therebetween to form a second air outlet channel, one end port (i.e. Figure 11 the left end port as shown) of the second air inlet pipe 14 and the second air outlet pipe 15 is located on the second side wall 13, and the other end port (i.e. Figure 11 the right end port as shown) of the second air inlet pipe 14 and the second air outlet pipe 15 extends into the liquid storage cavity 11.

[0066] In the above, by adopting the double-layer sleeve structure of the second air inlet pipe 14 and the second air outlet pipe 15, not only the water tank structure can be simplified and the liquid storage cavity space can be saved, but also the disturbance to the airflow can be reduced, and the annular second air outlet channel can naturally comb the airflow to avoid the conditions of turbulent flow and turbulent flow. Among them, the second air inlet pipe 14 and the second air outlet pipe 15 are preferably straight pipes, and the second air inlet pipe 14 can also be used as a water inlet pipe to add water to the water tank 10.

[0067] Among them, as a preferred, the left end port of the second air inlet pipe 14 and the second air outlet pipe 15 is located at the upper position of the second side wall 13 and at the middle position of the front and rear direction of the second side wall 13, so that when the water tank 10 is inclined due to carrying, moving and the like, the water in the water tank 10 will not appear the situation of pouring into the second air inlet pipe 14 and the second air outlet pipe 15.

[0068] Among them, referring to Figure 9 , as a preferred, the length of the second air inlet pipe 14 is greater than the length of the second air outlet pipe 15, the right end port of the second air outlet pipe 15 is located on the right side of the water tank center line (see Figure 9 the dashed line), the right end port of the second air inlet pipe 14 is formed as an inclined port 141, and the wall opposite to the inclined port 141 of the water tank 10 is formed as an inclined wall 16, so that the gas from the inclined port 141 is refracted to the lower middle area of the liquid storage cavity 11.

[0069] As shown by the arrows in Figure 9 , when the gas flows out of the second air inlet pipe 14, it flows in the direction of the water surface after being refracted by the inclined wall 16, and then enters the second air outlet channel after being refracted multiple times by the water surface and other side walls of the water tank 10, and then flows out of the second air outlet channel. The whole flow process of the gas will carry warm and humid water, so that the gas has good humidifying effect. Moreover, as shown in Figure 9 , the internal structure of the water tank 10 is simple and has no redundant parts, and the airflow in the water tank 10 only experiences a few refraction processes and does not appear turbulent flow and turbulent flow phenomena.

[0070] In order to realize the cooperation with the second air inlet pipe 14 and the second air outlet pipe 15, as shown in Figures 9-11As shown, the water tank mounting structure may further include a first air inlet pipe 24 and a first air outlet pipe 25. The first air inlet pipe 24 is coaxially inserted into the first air outlet pipe 25 and has a radial gap between it and the first air outlet pipe 25 to form a first air outlet channel. One end port of the first air inlet pipe 24 and the first air outlet pipe 25 (i.e. Figure 9 The right end port shown is located on the first side wall 23. The right end ports of the first air inlet pipe 24 and the first air outlet pipe 25 can be sealed and connected to the left end ports of the second air inlet pipe 14 and the second air outlet pipe 15 through the sealing member 26. It can be understood that the first air inlet pipe 24 is connected to the second air inlet pipe 14, and the first air outlet pipe 25 is connected to the second air outlet pipe 15 (that is, the first air outlet channel is connected to the second air outlet channel).

[0071] In the above, such as Figure 12 As shown, the sealing element 26 is an annular element, including an inner ring 261 and an outer ring 262 coaxially sleeved. The inner cavity of the inner ring 261 is used to connect the first air intake pipe 24 and the second air intake pipe 14. The inner ring 261 and the outer ring 262 have a radial gap to form a connecting channel for connecting the first air outlet channel and the second air outlet channel.

[0072] In addition, such as Figure 12 As shown, the inner ring 261 and the outer ring 262 can be connected by multiple spaced-apart connecting ribs 263. The arrangement of the connecting ribs 263 can divide the connecting channel into multiple arc-shaped channels, thereby achieving airflow routing. Correspondingly, as... Figure 2 and Figure 3 As shown, the second air inlet pipe 14 and the second air outlet pipe 15, as well as the first air inlet pipe 24 and the first air outlet pipe 25, can be connected by connectors to divide the second air outlet channel and the first air outlet channel into multiple arc-shaped channels. These arc-shaped channels correspond to the arc-shaped channels of the sealing member 26 to effectively manage the airflow and reduce aerodynamic noise.

[0073] The seal 26 may be made of sealing materials such as rubber or silicone.

[0074] By adopting the above configuration, not only is the structure simplified and space saved, but airflow disturbance is also minimized. The annular air outlet channel can also naturally manage the airflow, avoiding turbulence and disturbance. Moreover, the inlet and outlet pipes are built-in, and the ports are connected using the seal 26, so that the disassembly and assembly of the water tank 10 are not affected by the inlet and outlet pipes, making the disassembly and assembly of the water tank more convenient. At the same time, it also makes the water tank installation structure occupy less space.
