[0049] The existing water tank locking technology is generally manual locking and manual release. If the locking is forgotten and the water tank is not locked, it will cause the equipment to malfunction. Or, if the equipment is moved while the water tank is not locked, it will fall into the water tank and cause damage or accidents.

[0050] To address the aforementioned problems, this utility model proposes a locking device and a hookah device, aiming to provide a locking device and hookah device that facilitate automatic locking of the water tank. Figures 1 to 6 This is a schematic diagram of one embodiment of the locking device of this utility model.

[0051] Please refer to Figures 1 to 3 In one embodiment of this utility model, the locking device 100 includes a bracket assembly 1 and a first locking component; the bracket assembly 1 has a receiving groove 11 for receiving a water tank 10; the first locking component includes a locking member 21, which is movably installed on the side wall of the receiving groove 11 and has a locked state in a first position and an unlocked state in a second position; wherein, when the water tank 10 is inserted into the receiving groove 11 from outside the receiving groove 11, the locking member 21 moves from the second position to the first position and is in a locked state relative to the water tank 10, so as to fix the water tank 10 relative to the bracket assembly 1.

[0052] The technical solution of this utility model is to use a receiving groove 11 provided in the bracket assembly 1 to receive the water tank 10, and then lock the water tank 10 by the locking member 21 movably installed on the side wall of the receiving groove 11. Specifically, the locking member 21 has a locked state in a first position and an unlocked state in a second position. When the water tank 10 is received in the receiving groove 11, the locking member 21 moves from the second position to the first position, and then the locking member 21 is in a locked state relative to the water tank 10. This setting avoids accidents caused by the user forgetting to lock the water tank 10.

[0053] Further, please refer to Figures 1 to 3 The locking member 21 is arranged in a ring shape and has a rotational stroke along its axis. Both the first position and the second position are within the rotational stroke of the locking member 21. It is understood that in some embodiments, the locking member 21 can also move linearly. For example, when the water tank 10 is housed in the receiving groove 11, the locking member 21 is inserted into the receiving groove 11 from outside the bracket assembly 1, thereby fixing it relative to the water tank 10. This also achieves locking of the water tank 10. However, such an arrangement inevitably requires more space. Therefore, in another embodiment, the locking member 21 is arranged in a ring shape and has a rotational stroke along its axis. Both the first position and the second position are within the rotational stroke of the locking member 21. With this arrangement, by twisting the locking member 21, it can move between the first position (locked state) and the second position (unlocked state) without occupying additional space. Thus, the locking device 100 has the technical advantages of simple structure and ingenious arrangement.

[0054] Further, please refer to Figure 2 and Figure 3 The inner wall of the locking member 21 is provided with a plurality of limiting wedges 211, which are evenly spaced. The outer periphery of the water tank 10 is provided with a pairing wedge 101 that is correspondingly arranged to the plurality of limiting wedges 211. When the plurality of limiting wedges 211 and the plurality of pairing wedges 101 are engaged in a one-to-one correspondence, the locking member 21 is located in the first position. When the plurality of limiting wedges 211 and the plurality of pairing wedges 101 are staggered, the locking member 21 is located in the second position.

[0055] Understandably, in order to fix the water tank 10 relative to the bracket assembly 1 using the locking member 21, the inner wall of the locking member 21 is provided with a plurality of limiting wedges 211, which are evenly spaced. The outer periphery of the water tank 10 is provided with corresponding mating wedges 101, which are protruding from the plurality of limiting wedges 211. Both the limiting wedges 211 and the mating wedges 101 are inclined. By rotating the locking member 21, the locking member 21 rotates to the first position, that is, the locking member 21 maintains the lock. In the fixed position, the limiting wedge 211 and the mating wedge 101 move along their inclined sides until they are locked together. Alternatively, the locking member 21 can be rotated to the second position, which is the position where the locking member 21 is in the unlocked state. In this position, the limiting wedge 211 and the mating wedge 101 move away from each other until their horizontal projections are completely offset. This indicates that the locking member 21 has released the lock on the water tank 10.

[0056] Further, please refer to Figure 1 The locking member 21 has an operating part 212 protruding from its periphery. The operating part 212 extends outward from the inside of the bracket assembly 1 to drive the locking member 21 to rotate between the first position and the second position. It can be understood that the operating part 212 is provided to facilitate the rotation of the locking member 21 between the first and second positions. By operating the operating part, the locking member 21 can be driven to rotate between the first and second positions. Thus, the user can adjust the locking member 21 to the second position and keep it unlocked when assembling the water tank 10, then insert the water tank 10, and then drive the locking member 21 to rotate back to the first position using the operating part 212, thereby achieving the fixed installation of the water tank 10.

[0057] Further, please refer to Figure 1The locking device 100 further includes a limiting ring 3, which is fixedly disposed relative to the bracket assembly 1, and the two inner sidewalls of the limiting ring 3 are respectively disposed in a one-to-one correspondence with the first position and the second position; wherein, the operating part 212 extends from the inside of the bracket assembly 1 to the inside of the limiting ring 3. It is understandable that, since the locking member 21 has a first position in a locked state and a second position in an unlocked state along the annular rotation stroke of the locking member 21, in order to avoid excessive rotation during locking, which would cause the limiting wedge 211 and the mating wedge 101 to disengage from the mating surface, or excessive rotation during unlocking, which would cause the limiting wedge 211 and the mating wedge 101 to remain partially stuck, the locking device 100 also includes a limiting retaining ring 3, which is fixedly set relative to the bracket assembly 1, and the two inner sidewalls of the limiting retaining ring 3 are respectively set one-to-one with the first position and the second position; wherein, the operating part 212 extends from the inside of the bracket assembly 1 outward into the limiting retaining ring 3. With this setting, whether the user needs to lock or unlock, it is only necessary to rotate the operating part 212 to one of the two sidewalls of the limiting retaining ring 3 corresponding to the first position or the second position, thereby ensuring the reliability of the locking device 100 in locking and unlocking the water tank 10.

[0058] In addition, please refer to Figure 3 and Figure 4 The first locking assembly further includes a ring torsion spring 22, one end of which is fixed to the bracket assembly 1, and the other end is driven to connect to the locking member 21; wherein, the ring torsion spring 22 stores elastic potential energy so that the locking member 21 always has a rotational tendency from the second position to the first position. Understandably, to further ensure the reliability of the locking device 100 in locking the water tank 10, the first locking assembly also includes the annular torsion spring 22. One end of the annular torsion spring 22 is fixed to the bracket assembly 1, and the other end is driven to connect to the locking member 21. The annular torsion spring 22 stores elastic potential energy, so that the locking member 21 always has a tendency to rotate from the second position to the first position. With this configuration, when the water tank 10 is installed into the receiving groove 11, the locking member 21 rotates to the first position to lock the water tank 10. At this time, due to the elastic potential energy stored in the annular torsion spring 22, the locking member 21 is firmly pressed into the first position. Therefore, when the hookah device 200 is picked up, or no matter what kind of collision the hookah device 200 undergoes, the water tank 10 will not fall out of the receiving groove 11. Thus, the reliability of the locking member 21 in locking the water tank 10 is further ensured.

[0059] In addition, please refer to Figures 3 to 5 The locking device 100 further includes a second locking component, which is disposed on the locking member 21. When the water tank 10 is detached from the receiving groove 11, the second locking component locks the locking member 21 in the second position. When the water tank 10 is installed into the receiving groove 11, the second locking component releases its lock relative to the locking member 21. Understandably, in some embodiments, since the annular torsion spring 22 always stores elastic potential energy, the locking member 21 has a rotational stroke from the second position to the first position. Therefore, if the water tank 10 is removed from the receiving groove 11 for cleaning and cooling water replacement, the user needs to drive the locking member 21 to the second position through the operating part 212. After releasing the user, the locking member 21 returns to the first position under the drive of the annular torsion spring 22. After the water tank 10 is cleaned and replaced with new cooling water, it needs to be reinstalled into the receiving groove 11. The user then needs to drive the locking member 21 to the second position again through the operating part 212. Such operation is too complicated.

[0060] Therefore, please refer to Figure 4 In another embodiment, the locking device 100 further includes a second locking component disposed on the locking member 21. When the water tank 10 is detached from the receiving groove 11, the second locking component locks the locking member 21 in the second position. When the water tank 10 is installed into the receiving groove 11, the second locking component releases its lock relative to the locking member 21. This achieves a locked state where the locking member 21 is in the first position if the water tank 10 is in the receiving groove 11, and unlocked state where the water tank 10 is not in the receiving groove 11. In other words, the locking member 21 has a definite position and state depending on whether the water tank 10 is in the receiving groove 11, thereby reducing operation steps and also serving to remind the user whether the water tank 10 is properly installed.

[0061] Further, please refer to Figure 4 and Figure 5The inner sidewall of the receiving groove 11 of the bracket assembly 1 is provided with a ring-shaped mounting plate 111 to support the locking member; the mounting plate 111 has a limiting hole 1111 through the portion of the locking member 21 located at the second position, and the locking member 21 has a recessed groove 213 on the end face facing the mounting plate 111; the second locking assembly includes a limiting hole 1111 and an elastic member 42; the limiting block 41 is movably installed in the groove 213; the elastic member 42 is housed in the groove 213, and its two ends are respectively connected to the bottom of the groove 213 and the limiting block 41; wherein, when the locking member 21 moves from the first position to the second position, the elastic member 42 drives the limiting block 41 to embed into the limiting hole 1111, so that the locking member 21 is locked in the second position.

[0062] It is understood that whether the water tank 10 is accommodated in the receiving groove 11 can be determined by the position of the locking member 21. That is, in order to ensure that when the water tank 10 is in the receiving groove 11, the locking member 21 is in the first position and remains locked, and when the water tank 10 is detached from the receiving groove 11, the locking member 21 is in the second position and remains unlocked, specifically, the inner sidewall of the receiving groove 11 of the bracket assembly 1 has a protruding, annularly arranged mounting plate 111 to support the locking member. The mounting plate 111 has a limiting hole 1111 through the portion of the locking member 21 in the second position, and the locking member 21 has a recessed groove 213 on the end face facing the mounting plate 111. The second locking assembly includes the limiting hole 1111 and the elastic member 42; the limiting block 41 is movably installed in the recessed groove 213. Within the groove 213, the elastic element 42 is housed within the groove 213, with its two ends connected to the bottom of the groove 213 and the limiting block 41, respectively. When the locking element 21 moves from the first position to the second position, the elastic element 42 drives the limiting block 41 to embed into the limiting hole 1111, thereby locking the locking element 21 in the second position. With this configuration, when the water tank 10 needs to be removed from the receiving groove 11, the user drives the locking element 21 to rotate from the first position to the second position via the operating part 212. When the groove 213 of the locking element 21 aligns with the limiting hole 1111 of the mounting plate 111 in the second position, the elastic element 42 drives the limiting block 41 to embed into the limiting hole 1111, thereby locking the locking element 21 in the second position and allowing the water tank 10 to be removed.

[0063] Further, please refer to Figure 5The mounting plate 111 is also provided with a guide hole 1112, which is elongated and has one end connected to the limiting hole 1111 and the other end corresponding to the first position of the locking member 21. The limiting block 41 is provided with a guide pin 411. When the side wall of the water tank 10 is inserted into the receiving groove 11, its side wall presses the guide pin 411, driving the limiting block 41 to disengage from the limiting hole 1111, thereby releasing the locking of the locking member 21 in the second position. The guide pin 411 slides with the locking member 21 to the first position within the guide hole 1112.

[0064] Understandably, when the water tank 10 is reinstalled into the receiving groove 11, the locking member 21 needs to be reset to the first position to lock the water tank 10. That is, the second locking component 4 needs to unlock the locking member 21 in the second position. Therefore, specifically, the mounting plate 111 is also provided with the guide hole 1112, which is elongated, with one end connected to the limiting hole 1111 and the other end corresponding to the first position of the locking member 21. The limiting block 41 is provided with the guide pin 411. When the side wall of the water tank 10 is inserted into the receiving groove 11, its side wall presses against the guide pin 411, driving the limiting block 41 to disengage from the limiting hole 1111, thereby releasing the locking of the locking member 21 in the second position. The guide pin 411 is located in the first position of the receiving groove 11. The locking member 21 slides to the first position within the hole 1112. With this configuration, when the water tank 10 is reinstalled in the receiving groove 11, its sidewall will press against the guide pin 411, thereby pushing the limiting block 41 out of the limiting hole 1111. Thus, the locking member 21 is unlocked in the second position. Simultaneously, the elastic potential energy stored in the annular torsion spring 22 drives the locking member 21 to move to the first position, causing the limiting wedge 211 protruding from the locking member 21 to engage with the mating wedge 101 protruding from the water tank 10. This achieves automatic locking when the water tank 10 is installed in the receiving groove 11, reducing user steps and preventing accidents caused by forgetting to lock the water tank 10 or the water tank 10 not being properly locked, further improving the reliability and safety of the locking mechanism.

[0065] This utility model also proposes a water pipe device 200, please refer to it. Figure 6 The hookah device 200 includes the locking device 100. The specific structure of the locking device 100 is as described in the above embodiments. Since the hookah device 200 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
