[0036] like Figures 1-6As shown, this embodiment provides a locking and unlocking mechanism, which includes a base 1, a plug-in component 2, a locking assembly 3, an unlocking assembly 4, and a fixing assembly 5. When the plug-in component 2 is slidably inserted into the base 1 along a first direction, the locking assembly 3 can lock the plug-in component 2 on the base 1. The unlocking assembly 4 includes an unlocking member 41, which is slidably arranged on the base 1. When the unlocking member 41 slides to the unlocking position, the fixing assembly 5 can lock the unlocking member 41 in the unlocking position, thereby unlocking the plug-in component 2 from the base 1. When the plug-in component 2 is withdrawn from the base 1 along the first direction, the unlocking member 41 returns to its initial position.

[0037] In this embodiment, when the plug 2 is slidably inserted into the base 1 in the first direction, the locking assembly 3 locks the plug 2 to the base 1. This locking assembly 3 allows the plug 2 to be easily inserted into the base 1 and automatically locked, eliminating the need for manual operation and simplifying the installation process. When the unlocking member 41 slides to the unlocked position, the plug 2 is unlocked from the base 1, allowing the plug 2 to be withdrawn from the base 1 in the first direction. The fixing assembly 5 locks the unlocking member 41 in the unlocked position, ensuring that the unlocking member 41 remains stable in the unlocked position, facilitating the unlocking and withdrawal of the plug 2 and preventing displacement of the unlocking member 41 that could affect the unlocking of the plug 2. When the plug 2 is withdrawn from the base 1 in the first direction, the unlocking member 41 returns to its initial position, facilitating the next installation and removal of the plug 2 from the base 1. Through this arrangement, the locking and unlocking mechanism of this embodiment automatically locks the water tank and base 1 in a pet water dispenser, making unlocking more convenient and quicker.

[0038] It should be noted that the locking and unlocking mechanism of this embodiment is applied to devices such as pet drinking fountains or pet feeders. Correspondingly, the plug-in component 2 is a accommodating component such as a water tank or a feeding bowl. The plug-in component 2 can be disassembled and assembled relative to the base 1. The locking and unlocking mechanism can achieve rapid locking and unlocking between the plug-in component 2 and the base 1, making the operation more convenient and quick.

[0039] The specific structure of the locking and unlocking mechanism is described below:

[0040] Specifically, if Figure 2-Figure 4As shown, the locking assembly 3 includes a first locking member 31, which is slidably mounted on the base 1 along the second direction. The plug-in component 2 is provided with a locking groove 21. When the first locking member 31 extends into the locking groove 21, the plug-in component 2 is locked to the base 1. That is, after the plug-in component 2 is inserted into the base 1 and is properly positioned, the first locking member 31 is moved along the second direction to lock the plug-in component 2, thereby achieving a simple and effective locking operation without the need for additional tools or complex operations. In this embodiment, the first and second directions are mutually perpendicular horizontal directions to increase the stability and reliability of the locking. In other embodiments, the first and second directions can be adjusted according to actual usage requirements and are not further limited here.

[0041] Specifically, if Figure 2-Figure 4 As shown, the locking assembly 3 also includes a first elastic member 32, one end of which abuts the base 1 and the other end abuts the first locking member 31. The first locking member 31 extends into the locking groove 21 under the support of the first elastic member 32. When the plug 2 is not yet inserted into the base 1, the first locking member 31 is in a ready-to-lock state under the support of the first elastic member 32. When the plug 2 slides along the first direction and is inserted into the base 1, the plug 2 comes into contact with the first locking member 31 and is gradually pushed into the base 1, causing the first elastic member 32 to compress and accumulate elastic potential energy. When the locking groove 21 of the plug 2 is aligned with the first locking member 31, the first elastic member 32, under the action of the elastic potential energy, pushes the first locking member 31 into the locking groove 21, thereby completing the locking action and achieving automatic locking between the base 1 and the plug 2. In this embodiment, the first elastic member 32 is a spring or elastic rubber pad, etc., which is not further limited here.

[0042] More specifically, if Figure 2 As shown, in this embodiment, the first locking member 31 is a buckle, the base 1 includes an installation box 11, the buckle is slidably connected to the installation box 11 along the second direction, and one end of the buckle is provided with a sliding surface, the sliding surface is inclined, and is set at an angle to the first direction. When the plug-in component 2 is inserted into the base 1 along the first direction, the sliding surface of the buckle slides with the outer wall of the plug-in component 2, and the plug-in component 2 pushes the sliding surface of the buckle, so that the buckle retreats to the installation box 11 until the buckle extends into the locking groove 21 under the support of the spring, thereby realizing automatic locking between the plug-in component 2 and the base 1.

[0043] More specifically, in other embodiments, the first locking member 31 is a locking rod, which is connected to the first elastic member 32 and can extend into the locking groove 21 under the support of the first elastic member 32, that is, the specific structure of the first locking member 31 is not limited, as long as it can achieve the above-mentioned functional effects.

[0044] Specifically, if Figure 2-Figure 4As shown, the unlocking member 41 is provided with a guide groove 411, and the first locking member 31 is slidably connected to the guide groove 411. When the unlocking member 41 slides, the inner wall of the guide groove 411 pushes the first locking member 31, and the first locking member 31 can be pulled out of the locking groove 21. The user only needs to slide the unlocking member 41 to use the inner wall of the guide groove 411 to push the first locking member 31, which not only improves the automation and accuracy of unlocking, but also simplifies the operation process, allowing the user to complete the unlocking action more conveniently and quickly.

[0045] More specifically, if Figure 2 and Figure 4 As shown, in this embodiment, the unlocking member 41 is a slider that is slidably connected to the installation box 11 along a first direction and is provided with a dial button 413. The installation box 11 is provided with a slide groove extending along the first direction. The dial button 413 extends from the slide groove and is slidably connected to the slide groove, so that the user can dial the dial button 413 to cause the unlocking member 41 to slide relative to the base 1 along the first direction, thereby achieving the unlocking operation between the base 1 and the plug 2. Moreover, the slider extends along the first direction, and a guide groove 411 is formed at one end of the slider near the first locking member 31. The bottom end of the first locking member 31 is provided with a slide rod that slidably cooperates with the guide groove 411. When the user dials the dial button 413 toward the unlocked position, the inclined sidewalls of the guide groove 411 push against the slide rod, causing the first locking member 31 to be withdrawn from the locking groove 21, thereby achieving the unlocking operation between the plug 2 and the base 1.

[0046] Specifically, if Figure 2 and Figure 4 As shown, the unlocking assembly 4 also includes a second elastic member 42, one end of the second elastic member 42 abuts against the base 1, and the other end abuts against the unlocking member 41. The unlocking member 41 is located in the initial position under the support of the second elastic member 42, so that the unlocking member 41 can be restored to the initial position under the support of the second elastic member 42 when the external force is released.

[0047] More specifically, in this embodiment, the second elastic member 42 is a spring, one end of which abuts the inner wall of the installation box 11 and the other end abuts the unlocking member 41, so that the button 413 of the unlocking member 41 abuts one end of the slide slot, thereby ensuring that the unlocking member 41 remains stable in its initial position, facilitating user operation. In other embodiments, the second elastic member 42 is an elastic foot pad, which is not particularly limited here, as long as it can achieve the above-mentioned functions.

[0048] Specifically, if Figure 2-Figure 6As shown, the fixing assembly 5 includes a fixing member 51 and a third elastic member 52. The fixing member 51 is rotatably arranged on the base 1. The plug-in member 2 is provided with a snap-in groove 22. One end of the third elastic member 52 is connected to the base 1, and the other end is connected to the fixing member 51. When the plug-in member 2 is slidably inserted into the base 1 along the first direction, the fixing member 51 can be snapped into the snap-in groove 22 under the tensile action of the third elastic member 52, thereby improving the installation stability between the plug-in member 2 and the base 1 and preventing the plug-in member 2 from detaching.

[0049] Specifically, if Figure 2 and Figure 6 As shown, a sliding groove 412 is provided on the unlocking member 41, one end of the fixing member 51 is configured to be clamped in the clamping groove 22, and the other end is slidably set in the sliding groove 412, and a protrusion 4121 is provided on the inner wall of the sliding groove 412. The other end of the fixing member 51 can abut against the protrusion 4121 under the stretching action of the third elastic member 52 to interfere with the sliding of the unlocking member 41 relative to the base 1, thereby stopping the unlocking member 41 at the initial position and the unlocking position to ensure the normal locking and unlocking operations of the user.

[0050] More specifically, in this embodiment, the fixing member 51 is a stopper rod, which is pivotally connected to the mounting box 11 at its midsection. One end of the stopper rod is provided with a snap-fitting protrusion that snaps into the snap-fitting groove 22, thereby further locking the plug 2 and the base 1. Furthermore, the third elastic member 52 is a tension spring, one end of which is connected to the mounting box 11 and the other end to the other end of the stopper rod. When the plug 2 is slidably inserted into the base 1 in the first direction, one end of the stopper rod snaps into the snap-fitting groove 22, while the other end abuts the unlocking member 41 under the tension of the tension spring. In other embodiments, the fixing member 51 may be a block-shaped structure, and the third elastic member 52 may be a compression spring. The specific structures of these components are not particularly limited herein, as long as they can achieve the aforementioned functions.

[0051] Specifically, if Figure 6As shown, the raised portion 4121 includes a first arcuate segment 41211 and a second bent segment 41212. When the other end of the fixing member 51 abuts the first arcuate segment 41211, the unlocking member 41 is in its initial position, ensuring that the unlocking member 41 maintains a stable initial position before and after the plug 2 is installed on the base 1. When the other end of the fixing member 51 abuts the second bent segment 41212, it interferes with the sliding movement of the unlocking member 41 relative to the base 1, causing the unlocking member 41 to be in the unlocked position, thereby facilitating the user's removal of the plug 2 from the base 1 and preventing the unlocking member 41 from moving when the plug 2 is unlocked, which would cause the first locking member 31 to re-enter the locking groove 21, thereby ensuring normal unlocking operation between the plug 2 and the base 1. When the unlocking member 41 slides and switches from the initial position to the unlocking position, the first arc segment 41211 can push the other end of the fixing member 51, causing the fixing member 51 to rotate around the axis relative to the base 1 until the other end of the fixing member 51 abuts against the second bending segment 41212, thereby limiting the unlocking member 41 to the unlocking position.

[0052] Specifically, if Figure 2-Figure 6 As shown, the snap-fit ​​groove 22 extends along the first direction and can be slidably engaged with one end of the fixing member 51. When the plug-in member 2 is pulled out from the base 1 along the first direction, the snap-fit ​​groove 22 can push one end of the fixing member 51 so that the other end of the fixing member 51 is disengaged from the second bending section 41212, thereby releasing the interference with the unlocking member 41, so that the unlocking member 41 can be reset to the initial position under the stretching action of the second elastic member 42, so as to facilitate the next locking and unlocking operation.

[0053] More specifically, if Figure 2 and Figure 6 As shown, the inner depth of the snap-in groove 22 first increases and then decreases along the first direction, that is, the overall structure of the snap-in groove 22 is a wave structure. When the plug-in component 2 is pulled out from the base 1, the snap-in groove 22 is provided with a fixing portion at the end away from the base 1 that is snap-fitted with the fixing component 51. The inner wall of the snap-in groove 22 can push one end of the fixing component 51, so that the fixing component 51 rotates around the axis, thereby enabling one end of the fixing component 51 to be separated from the fixing portion, and the other end of the fixing component 51 can be released from the abutment with the second bending section 41212, thereby facilitating the reset of the unlocking component 41.

[0054] The specific working process of the locking and unlocking mechanism is described below:

[0055] When the user needs to assemble the plug 2 and the base 1, the user needs to hold the plug 2 and slide it in the first direction to insert it into the base 1. The plug 2 will come into contact with the first locking member 31 and gradually be pushed into the base 1. At this time, the first elastic member 32 will compress and accumulate elastic potential energy. When the locking groove 21 of the plug 2 is aligned with the first locking member 31, the first elastic member 32, under the action of the elastic potential energy, pushes the first locking member 31 into the locking groove 21, thereby achieving automatic locking between the base 1 and the plug 2.

[0056] When it is necessary to unlock the plug-in component 2 from the base 1, the user needs to toggle the dial button 413 along the first direction so that the unlocking component 41 slides to the unlocking position. During the sliding process of the unlocking component 41, the inner wall of the guide groove 411 will push the first locking component 31, so that the first locking component 31 can be pulled out of the locking groove 21. At the same time, the first arc segment 41211 of the protrusion 4121 can push the other end of the fixing component 51, so that the fixing component 51 rotates around the axis relative to the base 1 until the other end of the fixing component 51 abuts against the second bent segment 41212, thereby interfering with the sliding of the unlocking component 41 and limiting the unlocking component 41 to the unlocking position, ensuring that the first locking component 31 is pulled out of the locking groove 21 and maintains a stable state, preventing the unlocking component 41 from retreating under the pulling action of the second elastic component 42, causing the first locking component 31 to extend into the locking groove 21 again. This makes it easier for the user to pull the plug 2 out of the base 1. During the process of pulling the plug 2 out of the base 1 along the first direction, the engaging groove 22 can push one end of the fixing member 51 so that the other end of the fixing member 51 is disengaged from the second bending section 41212, thereby releasing the interference with the unlocking member 41, so that the unlocking member 41 can be restored to the initial position under the pulling action of the second elastic member 42, so as to facilitate the next locking and unlocking operation.

[0057] This embodiment also provides a pet water dispenser, which includes a water dispenser body and a locking and unlocking mechanism. The locking and unlocking mechanism is arranged on the water dispenser body, which can realize automatic locking between the water tank and the base 1 in the pet water dispenser, and unlocking is more convenient and quick.

[0058] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
