The pull rod 46 cooperates with the slide groove 43 on the rack body 41 to achieve the locking and unlocking of the water tank 60. The gear 442 engages with the rack tooth 42, and can store force for the coil spring 441 during the forward movement of the rack body 41. After the water tank 60 is unlocked, the pop-up force released by the coil spring 441 is provided to the water tank 60 by the rack body 41. The coil spring 441 is used as an elastic member, which can provide a more stable elastic force, the force value will not increase or decrease sharply, and the volume is small.

[0032] The upper cover 20 is provided with a guide groove 21 for installing the rack body 41. The guide groove 21 is opened on the upper end surface of the upper cover 20, with the notch facing upward. The rack body 41 is limited in the guide groove 21. A guide rail 211 is provided at the notch of the guide groove 21. The rack body 41 is slidably set on the guide rail 211 and has only the degree of freedom along its length direction. The rack body 41 follows the second stroke of the water tank 60 in the guide groove 21 to complete the forward and backward movement. A cover plate 22 is also provided on the guide groove 21. The cover plate 22 cooperates with the upper part of the rack body 41 to press the rack body 41 and limit its degree of freedom in the vertical direction. The setting of the guide groove 21 can not only realize the installation of the rack body 41, but also realize the guidance of the rack body 41. The structure is simple and easy to assemble; and the guide groove 21 is opened on the upper end surface of the upper cover 20, and will not occupy the transfer space of other components. Therefore, it can have a sufficient length to make the entire movement process of the rack body 41 All are completed in the guide groove 21, so that the entire movement process of the rack body 41 has sufficient support force and precise guidance, and its coordination with other components is improved; there is a coordination gap between the rack body 41 and the bottom of the guide groove 21, the slide groove 43 and the rack tooth 42 are both arranged on the lower end surface of the rack body 41, and the pull rod 46 is arranged in the coordination gap, and a positioning column 23 is formed at the bottom of the mounting groove, and the pull rod 46 has two bent ends and a horizontal section, and the two bent ends are respectively bent vertically upward and downward, wherein the first bent end 461 cooperates with the slide groove 43, and the second bent end 462 is inserted in the positioning column 23 and can rotate. In order to limit the swing amplitude of the pull rod 46, so that it can better cooperate with the slide groove 43, and prevent the two bent ends of the pull rod 46 from being out of the corresponding coordination position, a limit block 24 is provided in the upper cover 20, and the limit block 24 is located above the horizontal section of the pull rod 46 and is arranged close to the positioning column 23.

[0033] The upper cover 20 is also provided with a mounting frame 25 for mounting the coil spring 441 assembly. The mounting frame 25 is arranged below the guide groove 21. The coil spring 441 is embedded in the mounting hole. The gear 442 is connected to the coil spring 441 through a rotating shaft. A matching hole is provided at the bottom of the guide groove 21. The gear 442 partially passes through the matching hole and engages with the rack teeth 42. The above arrangement makes full use of the installation space in the upper shell and saves assembly space. In addition, the above installation method enables the coil spring 441 assembly and the rack body 41 to obtain sufficient supporting force without local force and uneven force. The cooperation between the two is more reliable, and the gears 442 and the rack body 41 can be more reliable. The rack teeth 42 are continuously arranged along the length direction of the rack body 41. During the sliding process of the rack body 41, the gear 442 is always engaged with the rack teeth 42. The rack body 41 cooperates with the coil spring 441 through the gear 442. It can not only store force for the spring through movement to provide rebound power, but also enable the rack body 41 and the pull rod 46 that originally have no elasticity to obtain rebound tension, so that the first bent end 461 of the pull rod 46 is locked in the locking position, and finally the water tank 60 is locked; a damping wheel 45 is also embedded on the mounting frame 25, and the damping wheel 45 at least partially passes through the matching hole to engage with the rack teeth 42. The damping wheel 45 can provide unidirectional resistance to the movement of the rack body 41 to reduce the difference in moving speed of the water tank 60 when it is full of water and when it is empty. When the water tank 60 is full of water and moves forward, the damping wheel 45 does not provide resistance. When the water tank 60 is empty and moves backward, the damping wheel 45 provides resistance to avoid the water tank 60 from popping out and moving back too fast to optimize the user experience. When assembling the coil spring 441 and the damping wheel 45, it is only necessary to insert the coil spring 441 and the damping wheel 45 into the two mounting holes respectively. The mounting holes limit all degrees of freedom of the coil spring 441 and the damping wheel 45 except for falling off backward. In order to improve the installation stability of the coil spring 441 and the damping wheel 45, two retaining ribs 31 are provided at corresponding positions on the base 30 to limit the coil spring 441 and the damping wheel 45 respectively. In this embodiment, the upper cover 20 and the base 30 are both injection molded, and the guide groove 21, the mounting frame 25, and the limit block 24 on the upper cover 20 are all injection molded integrally with the upper seat, and the retaining rib 31 on the base 30 is also injection molded integrally with the base 30, which greatly improves the manufacturing and assembly efficiency and reduces the production cost.

[0034] The slide groove 43 matched with the first bent end 461 of the pull rod 46 includes a straight section 431 and a slide-in section 432, a locking section 433, and a slide-out section 434 connected in sequence. The locking section 433 is located between the slide-in section 432 and the slide-out section 434. The slide-in section 432, the locking section 433, and the slide-out section 434 are formed along the contour of the locking block 435. The first bent end 461 of the pull rod 46 slides around the locking block 435 under the action of the slide groove 43 and the rack body 41. The locking block 435 is formed with a locking angle 436. The locking section 433 and the unlocking section are inclined in the opposite direction along the contour of the locking block 435. The front end of the sliding-in section 432 extends forward to form a locking release section 437, which is located in front of the locking block 435, and the projection of the locking release section 437 in the direction perpendicular to the movement of the water tank 60 is located within the projection of the locking section 433 in the direction perpendicular to the movement of the water tank 60; the front end of the sliding-out section 434 extends forward to form a pop-up release section 438, which is located on one side of the locking block 435, and the projection of the pop-up release section 438 in the direction perpendicular to the movement of the water tank 60 is located outside the projection of the locking section 433 in the direction perpendicular to the movement of the water tank 60. The locking process of the water tank 60 is that the water tank 60 moves independently in the first stroke, and then pushes the locking pop-up mechanism to move together, the rack body 41 slides in the guide groove 21, and drives the gear 442 to rotate to store force for the coil spring 441. During the movement of the rack body 41, the first bent end 461 of the pull rod 46 reaches the locking release section 437 via the straight section 431 and the sliding section 432. At this time, the water tank 60 and the rack body 41 both reach the limit position of forward movement and are connected through the connecting mechanism 50. Stop pressing the water tank 60, the thrust exerted on the rack body 41 disappears, the elastic force accumulated in the coil spring 441 pulls the rack body 41 back, and the first bent end 461 of the pull rod 46 enters the locking section 433 from the locking release section 437 and reaches the locking angle 436. Under the action of the spring 441 and the locking block 435, the first bent end 461 is stuck at the locking angle 436 to complete the locking of the water tank 60; the pop-up process of the water tank 60 is to press the water tank 60 again, the rack body 41 is pushed, the second bent end 462 of the pull rod 46 is disengaged from the stuck position, and reaches the pop-up release section 438 through the locking section 433 to complete the unlocking. After stopping the pressing, the coil spring 441 provides rebound power for the rack body 41, and the second bent end 462 of the pull rod 46 enters the sliding section 434 and the straight section 431 in turn from the pop-up release section 438 to achieve pop-up. After the elastic force of the coil spring 441 is released, the water tank 60 is pulled, the water tank 60 completes the second stroke, and is disengaged from the locking pop-up mechanism, retreats alone, continues to complete the first stroke, and slides out of the installation cavity.

[0035] The connecting mechanism 50 includes a snap-fit ​​seat 51, which is integrally formed at the end of the rack body 41. A group of snap-fit ​​components are arranged in the snap-fit ​​seat 51, and the snap-fit ​​components include a lock core 52 and a return spring 53. The lock core 52 abuts against the return spring 53. The upper part of the front end surface of the water tank 60 is formed with a snap-fit ​​groove 61 that cooperates with the connecting mechanism 50. The snap-fit ​​groove 61 is provided with a snap edge 62. The water tank 60 is connected to the locking pop-up mechanism by snapping. In the process of the water tank 60 moving forward and backward, the snap-fit ​​and disengagement with the locking pop-up mechanism can be completed, thereby realizing the locking and opening of the water tank 60, and the operation is convenient. In order to limit the pop-up distance of the water tank 60 and prevent it from sliding out of the mounting seat, a stop block 55 perpendicular to the rack body 41 is formed between the clamping seat 51 and the rack body 41, a thrust plate 26 is provided in the upper cover 20, and a limit stop edge 212 is provided at the starting end of the guide groove 21. The rack body 41 cooperates with the thrust plate 26 and the limit stop edge 212 to limit the moving distance during the forward and backward movement.

[0036] The card seat 51 has an installation cavity that penetrates the side wall, and the lock core 52 and the return spring 53 are embedded in the installation cavity. The lock core 52 at least partially protrudes from the side wall of the card seat 51 in a non-stressed state; the lock core 52 is two, and the return spring 53 abuts between the two lock cores 52. The two lock cores 52 approach each other under the extrusion of the card edge 62, and move away from each other under the action of the elastic restoring force of the return spring 53; the lock core 52 includes a force-bearing end and an assembly end, and the force-bearing end has a hemispherical lock head 521, and the lock head 521 protrudes from the side wall of the card seat 51 in a non-stressed state. The hemispherical lock head 521 is more conducive to cooperating with the card edge 62, and is smoothly stressed during the extrusion process, and there will be no jamming feeling; the assembly end has an abutting surface and a stop surface, and the card edge 62 is pressed by the card edge 62. The end of the positioning spring 53 abuts against the abutment surface to effectively improve the matching reliability of the lock core 52 and the return spring 53. The extrusion force exerted on the lock core 52 can be effectively transmitted to the return spring 53, and the elastic restoring force of the return spring 53 can also be effectively transmitted to the lock core 52; after the card-connecting assembly is carded into place, the card-stop surface collides and contacts with the inner end surface of the side wall of the card-connecting seat 51 to make a sound, providing the user with sound feedback to accurately judge whether the water tank 60 is connected in place; when assembling the connecting mechanism 50, first install a lock core 52 into the installation cavity, then install the spring, and then install the other lock core 52, and finally tighten the end cover 54, so as to achieve quick assembly. During use, the pushing force and the separation force can be adjusted by adjusting the force value of the return spring 53.

[0037] The water tank 60 is injection molded, and the snap-in groove 61 is a square groove, which is molded on the upper part of the front end surface of the water tank 60 and is injection molded integrally with the water tank 60. It has a simple structure and is easy to manufacture. The two opposite side walls define a groove; there are two snap edges 62, which are respectively molded on the two side walls and are symmetrically arranged. The two snap edges 62 respectively cooperate with the two lock cores 52, and the snap connection is more reliable.

[0038] Two guiding slopes are provided on the clamping edge 62 to make the entire clamping and disengaging process smoother, wherein the first guiding slope 621 is provided close to the notch, and the second guiding slope 622 is provided close to the bottom of the groove; the slope of the first guiding slope 621 is smaller than the slope of the second guiding slope 622, and the connecting mechanism 50 cooperates with the first guiding slope 621 when entering the clamping groove 61. The smaller slope enables the connecting mechanism 50 to enter the clamping groove 61 under a smaller thrust, so as to realize the locking of the water tank 60 by the locking pop-up mechanism; when the connecting mechanism 50 is disengaged from the clamping groove 61, it cooperates with the second guiding slope 622, and the larger slope enables the clamping structure to be disengaged from the clamping groove 61 under a larger pulling force, so as to improve the locking reliability of the water tank 60, and at the same time avoid the water tank 60 being disengaged from the locking pop-up mechanism too early before reaching the predetermined position when taking out the water tank 60, thereby optimizing the user experience, and the magnitude of the pushing force and the separation force can be made different by changing the slopes of the two guiding slopes.

[0039] The water tank installation structure disclosed in the present invention combines the locking mechanism and the pop-up mechanism into one to realize the two functions of locking and pop-up, which can effectively reduce the assembly space and make the water tank component structure more compact; the locking pop-up mechanism is arranged on the upper part of the mounting seat, and the water tank 60 will not apply gravity to the locking pop-up mechanism during the process of cooperating with the locking pop-up mechanism, which can not only improve the cooperation reliability of the two, but also avoid the locking pop-up mechanism from being damaged due to local force; the water tank 60 is separately arranged from the locking pop-up mechanism, and operates independently during most of its movement stroke, and has no interaction force with the locking pop-up mechanism, which further improves the service life of the locking pop-up mechanism and can improve the sliding stability of the water tank 60; the water tank 60 and the locking pop-up mechanism are connected by a snap-on method, which is convenient to operate and reliable in connection.
