Detailed ways

The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

To facilitate the description of the water tank connection mechanism of the embodiment of the present application, a description is now given in conjunction with an example of the use of the water tank connection mechanism. It should be noted that the following example does not constitute the only example of the water tank connection mechanism of the embodiment of the present application.

1, a water tank connection mechanism 100 provided in an embodiment of the present application can be installed on a host 200, and the host 200 can be connected to a water tank 300 through the water tank connection mechanism 100. The water tank has a waterway interface 310, which is used to output the water in the water tank 300 to the outside of the water tank 300 and/or to connect the water flow from the water flow outside the water tank 300. The water tank connection mechanism 100 is provided with a water delivery pipeline 110, which is used to connect with the waterway interface 310, and can be used to transfer the water from the water tank 300 to the outside of the water tank 300 and/or to transfer the water flow from the outside of the water tank 300 to the water tank 300. After the host 200 is fixed to the water tank 300 through the water tank connection mechanism 100, one end of the water delivery pipeline 110 is connected to the waterway interface 310, and the other end of the water delivery pipeline 110 is connected to the waterway in the host 200.

In some embodiments, the host 200 can be used to heat the water in the water tank 300. The water tank 300 has a water channel interface 310 including a water inlet and a water outlet. Accordingly, the water tank connection mechanism 100 is provided with a water delivery pipeline 110 including a water inlet pipe and a water outlet pipe. One end of the water inlet pipe is connected to one end of the water channel of the host 200, the other end of the water inlet pipe is connected to the water outlet, one end of the water outlet pipe is connected to the other end of the water channel of the host 200, and the other end of the water outlet pipe is connected to the water inlet. The water in the water tank flows from the water outlet into the water inlet pipe and enters the host 200, and then flows back to the water tank from the water inlet into the water outlet pipe.

The specific structure of the water tank connecting mechanism 100 is described below.

2-4, the water tank connection mechanism 100 provided in the embodiment of the present application includes a water pipeline 110, a frame 120, a first stopper 130, a first operating member 140 and a first locking member 150. The first stopper 130 is mounted on the frame 120, the first operating member 140 is slidably mounted on the frame 120, the water pipeline 110 is arranged on the first operating member 140, and the pipe mouth of the water pipeline 110 is aligned with the waterway interface 310 in the first direction; the first locking member 150 is mounted on the first operating member 140, and when the first operating member 140 slides along the frame 120 in the first direction, the first locking member 150 moves relative to the first stopper 130 in the second direction to form a locking structure with the first stopper 130, and when the first locking member 150 forms a locking structure with the first stopper 130, the water pipeline 110 is connected with the waterway interface 310.

It should be noted that the frame 120 is provided with a guide rail 1200, and the first operating member 140 is connected to the guide rail 1200 to slide on the frame 120. For example, the guide rail 1200 may be a linear guide rail 1200, and the linear guide rail 1200 is fixed to the frame 120. The first operating member 140 may be directly sleeved on the linear guide rail 1200, or connected to a slider provided on the linear guide rail 1200, so as to slide on the linear guide rail 1200.

It is understandable that the first direction depends on the moving direction defined by the guide rail 1200. Taking the placement state of the water tank connection mechanism 100 shown in FIG2 as an example, the guide rail 1200 in the water tank connection mechanism 100 is placed vertically, and the first operating member 140 can move upward or downward along the frame on the guide rail 1200, and the first direction is downward. This embodiment is described by taking downward as the first direction as an example.

It should be noted that the downward movement of the first operating member 140 along the frame 120 can be operated by the user, that is, the user presses the first operating member 140 downward to move the first operating member 140 downward along the frame 120. Alternatively, the downward movement of the first operating member 140 along the frame 120 can also be controlled by the host 200, and a corresponding driving mechanism can be provided on the host 200. The host 200 controls the driving mechanism to apply a driving force to the first operating member 140, so that the first operating member 140 moves downward along the frame 120.

In this embodiment, the water channel interface 310 in the water tank 300 is arranged upward, and the water delivery pipeline 110 has a pipe opening facing downward, and the pipe opening is aligned with the water channel interface 310. When the first operating member 140 moves downward, the pipe opening of the water delivery pipeline 110 moves downward until it docks with the water channel interface 310.

In some embodiments, the water tank 300 may be formed with a groove, and the water channel interface is disposed in the groove. When the water delivery pipeline 110 is connected to the water channel interface 310, the first operating member 140 is inserted and connected to the water tank 300. The groove may play a certain limiting role, so as to limit the first operating member 140 to be separated only in the direction opposite to the insertion direction.

As an example, the water tank 300 may be formed with a groove that is concave downward, and the first operating member 140 moves downward to connect the water delivery pipeline 110 with the water channel interface 310. After the connection, the displacement of the first operating member 140 in the left and right and front and back directions is limited by the groove. The first operating member 140 can only be separated from the water tank 300 in the upward direction.

It should be noted that the locking structure formed by the first locking member 150 and the first limiting member 130 is mainly used to limit the first operating member 140 from moving in a direction opposite to the first direction along the frame 120. During the downward movement of the first operating member 140, the pipe mouth of the water pipeline 110 and the water channel interface 310 are first docked, and at the same time or thereafter, the first locking member 150 and the first limiting member 130 form a locking structure. In this way, due to the self-locking effect of the locking structure, the first operating member 140 cannot move upward, and the pipe mouth of the water pipeline 110 and the water channel interface 310 will not be separated.

In some embodiments, at least one of the first locking member 150 and the first limiting member 130 is a movable element, which can be displaced, such as rotating or running in a straight line, when subjected to a driving force. At the same time, a limiting structure that limits the movable element from moving in the opposite direction of the displacement direction, such as an undercut, can be formed between the first locking member 150 and the first limiting member 130. Since the first limiting member 130 is installed on the frame 120, its position is fixed. During the downward movement of the first operating member 140, the first locking member 150 moves downward with the first operating member 140. After the first locking member 150 and the first limiting member 130 come into contact, the movable element moves in its own moving direction. After the movable element is displaced a certain distance, the first locking member 150 and the first limiting member 130 cooperate to form a limiting structure based on the set structure, limiting the reverse recovery of the movable element, thereby forming a locking structure.

According to the water tank connection mechanism 100 of the present application, the water delivery pipeline 110 is connected to the water channel interface 310 on the water tank 300 by moving in the first direction, and the first locking member 150 and the first limiting member 130 form a locking structure to prevent the first operating member 140 from rebounding. When in use, the water tank connection mechanism 100 can be pressed to form a stable connection with the water tank 300, which is simple to operate and provides a good user experience.

In some embodiments of the present application, the first limit member 130 can be fixed to the frame 120, the first limit member 130 can have a raised surface, and the raised direction forms an angle greater than 0° with the first direction, for example, an angle of 90°, and the raised direction is perpendicular to the first direction; the first locking member 150 includes a hook, which is rotatably mounted on the first operating member 140. When the first operating member 140 slides along the frame in the first direction, the rotating end of the hook stops at the raised surface and moves along the raised surface to hook the first limit member 130 to form a locking structure.

As shown in FIG4 , the first stopper 130 can be fixedly connected to the frame 120. The first stopper 130 protrudes to the rear side on the frame 120, and the protruding portion has an inclined surface extending backward and downward. The bottom of the protruding portion is a horizontal plane, forming a step with the frame. One end of the hook is arranged on the first operating member 140 through a rotating shaft, and the rotating end of the hook has a hook portion. When the first operating member 140 moves downward, the rotating end of the hook contacts the upper part of the inclined surface. As the first operating member 140 continues to move downward, the rotating end of the hook moves backward and downward along the inclined surface, and the hook rotates counterclockwise relative to the first operating member 140. After moving to the lower end of the inclined surface, it disengages from the inclined surface, and the hook rotates clockwise relative to the first operating member 140, hooking the step surface, and limiting the first operating member 140 from retreating upward. . It can be understood that in some embodiments, the first limit member 130 can also be a convex surface or a concave surface, and the surface shape can be other shapes, such as an arc surface, an irregular surface, etc., as long as it can allow the first locking member 150 to move downward a certain distance and then be locked.

In this embodiment, the hook and the rotating shaft can be connected by a torsion spring. Before the hook moves downward, the hook keeps the hook portion above the raised portion under the action of the torsion spring. Therefore, after the hook moves downward and hooks the raised portion, it is not easy to disengage, making the locking structure more secure and improving the stability of the connection.

In other embodiments, the first position-limiting member 130 may also be a hook, and the hook portion is located at the top, and the first locking member 150 is a protruding portion fixed on the first operating member 140, and the protruding portion has an inclined surface extending backward and upward. The top of the protruding portion is a horizontal plane, forming a step with the frame 120. When the first operating member 140 moves downward, the lower part of the inclined surface of the protruding portion contacts the hook portion of the hook. As the first operating member 140 continues to move downward, the inclined surface pushes the hook hook to rotate clockwise relative to the frame 120. After the rotating end of the hook moves to the upper section of the arc surface, it disengages from the inclined surface, and the hook rotates counterclockwise relative to the frame 120, hooking the step surface, and limiting the first operating member 140 from retreating upward. It can be understood that in some embodiments, the first position-limiting member 130 and the first locking member 150 can also be locked in other ways. As long as the first locking member 150 moves downward a certain distance, it can be locked with the first position-limiting member 130. In some embodiments of the present application, referring to Figure 5, the water tank connecting mechanism may also include a second operating member 160, which is movably mounted on the first operating member 140, and the second operating member 160 has an extension portion 161, which is connected to the first locking member 150. When the second operating member 160 moves, the extension portion 161 drives the first locking member 150 to move in a third direction relative to the first limiting member 130 to release the locking structure.

4 , after the first locking member 150 hooks the first limiting member 130 , the extending portion 161 drives the first locking member 150 to move counterclockwise, so that the first locking member 150 can be separated from the first limiting member 130 , and the first operating member 140 can move upward.

In other embodiments, if the first position-limiting member 130 is a hook, and the hook portion is located at the top, and the first locking member 150 is a protruding portion fixed to the first operating member 140, the extension portion 161 on the second operating member 160 needs to drive the first position-limiting member 130 to move clockwise, so that the first locking member 150 is separated from the first position-limiting member 130.

In this embodiment, the second operating member 160 includes a first spring 162, a first end of the first spring 162 is fixed to the body of the second operating member 160, and a second end of the first spring 162 is fixed to the first operating member 140. The body of the second operating member 160 can move downward when pressed, so that the extension portion 161 drives the first locking member 150.

In some embodiments, the second operating member 160 may be disposed on the first operating member 140 via the guide rail 1200, and the second operating member 160 may move linearly along the guide rail 1200 on the first operating member 140 in the forward and backward directions. When the second operating member 160 moves backward, the extension 161 drives the first locking member 150 backward.

According to the water tank connecting mechanism 100 of the embodiment of the present application, by operating the second operating member 160 to move, the extension portion 161 on the second operating member 160 pushes the first locking member 150 to move in the third direction relative to the first limiting member 130 to release the locking structure, thereby disconnecting the water tank connecting mechanism 100 from the water tank 300. The operation is simple and the user experience is good.

In some embodiments of the present application, as shown in Fig. 6, the water tank connection mechanism 100 may further include an elastic member 170. A first end of the elastic member 170 is connected to the frame 120, and a second end of the elastic member 170 is connected to the first operating member 140. When the first operating member 140 slides in the first direction, the elastic member 170 is stretched.

It is understandable that when the nozzle of the water delivery pipeline 110 is connected to the water channel interface 310, the first operating member 140 has already produced a downward displacement, so the elastic member 170 is in a stretched state. At this time, the first operating member 140 is subjected to an upward elastic force, but because the first locking member 150 and the first limiting member 130 form a locking structure, the first operating member 140 cannot move upward. When the locking structure formed by the first locking member 150 and the first limiting member 130 is in contact, the first operating member 140 can move upward under the action of the elastic force, so that the nozzle of the water delivery pipeline 110 and the water channel interface 310 are automatically separated.

4, to facilitate the installation of components, the water tank connection mechanism 100 may further include a sliding member 192, which is disposed on the guide rail 1200. The sliding member 192 is connected to the first operating member 140, and the sliding member 192 moves along with the movement of the first operating member 140. The second end of the elastic member 170 is connected to the sheet metal member, and then indirectly connected to the first operating member 140. When the first operating member 140 moves downward, the sliding member 192 moves downward, driving the elastic member 170 to stretch downward. The elastic member 170 may be a second spring.

6 , as an example, the sliding member 192 may be a sheet metal member, and the upper end of the sheet metal member may be connected to the first operating member 140 by a buckle or other structure, or may be integrally connected. The middle portion of the sheet metal member may be connected to the slider 191 by a thread or other means to move up and down along the frame 120.

According to the water tank connecting mechanism 100 of the embodiment of the present application, the locking structure is released by operating the second operating member 160, thereby disconnecting the water tank connecting mechanism 100 from the water tank 300, and the elastic member 170 is used to automatically separate the water tank connecting mechanism 100 from the water tank 300, which is simple to operate and provides a good user experience.

4, in some embodiments of the present application, the first locking member 150 has a first through hole 151, and the water tank connection mechanism 100 may further include a second stopper 1100 and a latch mechanism 1110. The second stopper 1100 is fixed to the frame and has a second through hole 1110. When the first locking member 150 and the first stopper 130 form a locking structure, the first through hole 151 and the second through hole 1110 are aligned in the fourth direction; the latch mechanism 1110 is installed on the frame 120. When the first locking member 150 and the first stopper 130 form a locking structure, the latch mechanism 1110 extends a latch along the fourth direction so that the latch is inserted into the first through hole 151 and the second through hole 1110.

It is understandable that after the latch is inserted into the first through hole 151 and the second through hole 1110, the first locking member 150 is equivalent to being fixed to the frame 120. At this time, even if the aforementioned locking structure is released, the water tank connection mechanism 100 cannot rebound to continue to maintain the connection with the water tank 300, thereby preventing accidental contact.

In this embodiment, the latch mechanism 1110 may include an electromagnetic lock having a latch. The electromagnetic lock may be connected to the host 200, and when the host 200 runs a workflow, the electromagnetic lock receives a first control signal sent by the host 200 to pop out the latch. When the host 200 ends the workflow, the electromagnetic lock receives a second control signal sent by the host 200 to retract the electric latch. There are mature technologies for the structure and principle of the electromagnetic lock, and this embodiment will not be repeated here.

According to the water tank connecting mechanism 100 of the present application, the first locking member 150 is fixed by setting a latch mechanism 1110, so that even if the locking structure formed by the first locking member 150 and the first limiting member 130 is contacted and the latch pops out, the first operating member 140 cannot rebound, which can prevent accidental removal.

In some embodiments of the present application, an elastic sealing ring is provided at the pipe opening of the water delivery pipeline 110 .

In some embodiments, the elastic sealing ring includes a first connecting section and a second connecting section, the first connecting section and the second connecting section are connected, the first connecting section is provided with a first connecting channel, the second connecting section is provided with a second connecting channel, the first connecting channel and the second connecting channel are connected, the first connecting section is used to connect to the water nozzle, and the end of the second connecting section away from the first connecting section is used to press against the outer periphery of the connected water outlet. The second connecting section includes a straight section, the straight section is connected to the first connecting section, and the end of the straight section away from the telescopic corrugated section is low-pressure on the outer periphery of the water outlet. It can be understood that in this embodiment, the straight section surrounds the water outlet.

In some embodiments, the second connecting section includes at least one telescopic corrugated section, which is composed of two ring pieces, and the end faces of the outer edges and inner edges of the ring pieces are respectively located on different planes, wherein the outer edge of one ring piece is connected to the outer edge of the other ring piece, and the inner edges of the two ring pieces are respectively located on both sides, and the inner edge of one of the ring pieces of the telescopic corrugated section is connected to the second connecting section.

It can be understood that at least the telescopic bellows section is made of elastic waterproof material. Exemplarily, the telescopic bellows section is made of silicone material. When the end of the second connecting section is pressed against the outer periphery of the water outlet, the telescopic bellows section will be deformed, that is, it will be in a compressed state. In this way, on the one hand, it ensures that the end of the second connecting section is tightly pressed against the outer periphery of the water outlet. On the other hand, when the water nozzle and the water outlet are separated, the telescopic bellows section itself tends to elastically return to its original state, which makes it easier for the seal to detach from the outer periphery of the water outlet, thereby improving the convenience of disassembly and assembly between the water nozzle and the water outlet.

It can be understood that there is no limit to the number of telescopic corrugated segments. In this embodiment, the telescopic corrugated segments are arranged as two connected segments.

It is understandable that after the first operating member 140 is moved downward until the water pipeline 110 is connected to the water channel interface 310 , the elastic sealing ring is compressed, thereby sealing the connection between the water pipeline 110 and the water channel interface 310 .

7 , an embodiment of the present application further proposes a water tank connection mechanism 100, the water tank 300 may further be provided with a third limit member 320, the water tank connection mechanism 100 may further include a frame 120, a water pipeline 110, a first operating member 140 and a second locking member 180, the first operating member 140 is slidably mounted on the frame 120; the water pipeline 100 is arranged on the first operating member 140, and when the first operating member 140 moves to the target position, the water pipeline 110 is connected to the water channel interface 310, the second locking member 180 is movably mounted on the frame 120, and the second locking member 180 is used to form a locking structure with the third limit member 320 when the water pipeline 110 is connected to the water channel interface 310.

In some embodiments, the water tank 300 may be formed with a groove, and the water channel interface 310 is disposed in the groove. When the water delivery pipeline 110 is connected to the water channel interface 310, the first operating member 140 is inserted and connected to the water tank 300. The groove may play a certain limiting role, so as to limit the first operating member 140 to be separated only in the direction opposite to the insertion direction.

In this embodiment, the water tank 300 forms a locking structure by setting the third limiting member 320 and the second locking member 180 to stabilize the bottom of the water tank 300 and prevent the bottom of the water tank 300 from being separated from the water tank connection mechanism 100. The locking structure formed by the second locking member 180 and the third limiting member 320 can refer to the locking structure formed by the first locking member 150 and the first limiting member 130 in the above-mentioned embodiment.

In some embodiments, the first operating member 140 can be connected to the second locking member 180. When the first operating member 140 is in operation, it can drive the second locking member 180 to operate, thereby forming a locking structure between the second locking member 180 and the third limiting member. A reversing mechanism can be provided between the first operating member 140 and the second locking member 180, so that the operating directions of the two can be different. For example, the first operating member 140 can move up and down along the frame 120, and the second locking member 180 can move clockwise or counterclockwise along the frame 120.

In some embodiments, the movement of the second locking member 180 can be operated by the user, that is, the user drives the second locking member 180 to form a locking structure with the third limiting member 320. Alternatively, the movement of the second locking member 180 can also be controlled by the host 200, and a corresponding driving mechanism can be provided on the host 200. The host 200 controls the driving mechanism to apply a driving force to the second locking member 180, so that the second locking member 180 forms a locking structure with the third limiting member 320.

In some embodiments, the water tank 300 may not be provided with the third limiting member 320 , and the water tank may be clamped only by the relative movement of the first operating member 140 and the second locking member 180 .

According to the water tank connecting mechanism 100 of the present application, by operating the first operating member 140, the pipe mouth of the water supply pipeline 110 can be connected to the water channel interface 310, and at the same time, the second locking member 180 and the third limiting member 320 can be used to form a locking structure on the water tank 300 to fix it and prevent the water tank 300 from detaching.

In some embodiments of the present application, the water tank connection mechanism 100 further includes a transmission mechanism 110. The transmission mechanism 110 is mounted on the frame 120, and the transmission mechanism 190 is respectively connected to the first operating member 140 and the second locking member 180 in a transmission manner. When the first operating member 140 moves toward the water tank along the connection direction, the transmission mechanism 190 drives the second locking member 180 to move in a fifth direction relative to the third limiting member 320, so that the second locking member 180 and the third limiting member 320 form a locking structure.

It should be noted that the first operating member 140 is located at the top of the water tank 300, and the second locking member 180 is located at the bottom of the water tank 300. To avoid multiple operations, the transmission mechanism 190 is used to realize the linkage operation of the first operating member 140 and the second locking member 180. The first end of the transmission mechanism 190 can be integrally connected to the first operating member 140, or connected using an intermediate member. When the first operating member 140 moves, the transmission mechanism 190 also generates corresponding movement.

In some embodiments, the transmission mechanism 190 can be slidably mounted on the frame 120, and the sliding direction is the up-down direction. When the first operating member 140 moves downward, the transmission mechanism 190 also moves downward.

In some embodiments, the transmission mechanism 190 can be rotatably mounted on the frame 120, and when the first operating member 140 moves downward, the transmission mechanism 190 rotates around its rotation axis.

It should be noted that the second end of the transmission mechanism 190 can be in contact with the second locking member 180 at a specific position in the direction of its movement. That is, after the transmission mechanism 190 moves to the specific position, it will push the second locking member 180 to move. The movement directions of the transmission mechanism 190 and the second locking member 180 can be different, for example, the transmission mechanism 190 moves downward, and the second locking member 180 can be rotated or moved forward.

8 , in some embodiments of the present application, the third limiting member 320 may be a limiting groove, and the second locking member 180 may include a locking tongue 181 and a driving member 182. The driving member 182 is rotatably mounted on the frame 120 and is integrally connected with the locking tongue 181. When the transmission mechanism 190 slides in the first direction, the driving member 182 is pushed by the transmission mechanism 190 to rotate, so that the locking tongue 181 is rotationally extended into the limiting groove.

It should be noted that the opening of the limiting groove can be downward, and accordingly, the locking tongue 181 is driven by the driving member 182 to rotate from bottom to top and extend into the limiting groove. The width of the locking tongue 181 can be close to the opening of the limiting groove and be in an arc shape. After the locking tongue 182 extends into the limiting groove, the small gap between the locking tongue 182 and the opening of the limiting groove can ensure that the water tank 300 is not easy to shake. At the same time, the arc shape makes it easy to extend into the limiting groove in a rotating motion.

In this embodiment, the driving member 182 is mounted on the frame 120 via a rotating shaft, and a torsion spring may also be mounted on the rotating shaft. The driving member 182 is arranged to be tilted upward and backward. When the transmission mechanism 190 moves downward, the driving member 182 runs clockwise, so that the locking tongue 181 pops out. When the water tank connection mechanism 100 is connected to the water tank, the locking tongue 181 pops out and enters the limiting groove at the bottom of the water tank 300.

In some embodiments of the present application, the transmission mechanism 190 may include a slider 191, a sheet metal part and a contact part 193, the slider 191 is installed on the frame 120; the upper end of the sheet metal part is connected to the first operating part 140, and the middle part of the sheet metal part is connected to the slider 191; the contact part 193 is arranged at the lower end of the sheet metal part, and when the first operating part 140 slides in the first direction, the contact part 193 is used to push the driving part 182 to rotate.

In this embodiment, the upper end of the sheet metal part and the first operating member 140 can be connected by a buckle or other structure, or can be connected in an integrated manner. The middle part of the sheet metal part can be connected to the slider 191 by means of threads or other means. The slider 191 is set on the guide rail 1200 and moves up and down along the frame 120. When the first operating member 140 moves downward, the sheet metal part moves downward under the restriction of the slider 192.

In this embodiment, the contact member 193 may be formed of a plastic material. Since the contact member 193 needs to collide with the driving member 182, the use of a plastic material can reduce damage.

It should be noted that there can be multiple sliders 191. Since the sheet metal extends from the upper end to the lower end of the water tank connection mechanism 100 and has a long length, providing multiple sliders 191 can ensure the sliding stability of the sheet metal.

9 , an embodiment of the present application further provides a water tank connection mechanism 100. The water tank 300 is provided with a water channel interface 310 and a third stopper 320. The water tank connection mechanism 100 includes a water delivery pipeline 110, a frame 120, a first stopper 130, a first operating member 140, a first locking member 150 and a second locking member 180.

According to the water tank connection mechanism 100 of the present application, the water delivery pipeline 110 is connected to the water channel interface 310 on the water tank 300 by moving in the first direction, and the first locking member 150 and the first limiting member 130 form a locking structure to prevent the first operating member 140 from rebounding; at the same time, the second locking member 180 and the third limiting member 320 are used to form a locking structure on the water tank 300 to fix it to prevent the water tank 300 from detaching. When in use, the water tank connection mechanism 100 can be pressed to form a stable connection with the water tank 300, which is simple to operate and has a good user experience.

Continuing to refer to FIG. 4 , the first position-limiting member 130 can be integrally connected with the frame 120. The first position-limiting member 130 protrudes to the rear side on the frame 120, and the protruding portion has an inclined surface extending rearward and downward. The bottom of the protruding portion is a horizontal plane, forming a step with the frame. One end of the hook is arranged on the first operating member 140 through a rotating shaft, and the rotating end of the hook has a hook portion. When the first operating member 140 moves downward, the rotating end of the hook contacts the upper portion of the inclined surface. As the first operating member 140 continues to move downward, the rotating end of the hook moves backward and downward along the inclined surface, and the hook rotates counterclockwise relative to the first operating member 140. After moving to the lower end of the inclined surface, it disengages from the inclined surface, and the hook rotates clockwise relative to the first operating member 140, hooking the step surface, and limiting the first operating member 140 from retreating upward.

Continuing with reference to Figure 5, in some embodiments of the present application, the water tank connecting mechanism may further include a second operating member 160, which is movably mounted on the first operating member 140, and the second operating member 160 has an extension portion 161, which is connected to the first locking member 150.
