[0002] In order to keep a certain water level inside the container and regularly change the water inside the container to ensure cleanliness, it is necessary to replenish and drain the water in the container to realize regular replacement of the water in the container. In the prior art, the water replenishing device and the water draining device of the container are often set separately. Among them, the water replenishing device usually sets a water replenishing pump. The water level in the container is detected by a liquid level detection device inside the container. When the water level in the container drops to a predetermined height, the water replenishing pump is controlled to work, and external water is transported into the container through the water replenishing pump to realize water replenishment. The water draining device is to set a siphon or a drain pump inside the container, and the water inside the container is drained through the siphon or the drain pump. At the same time, in order to cooperate with the installation of devices such as a water replenishing pump and a drain pump, additional structures such as a suction head and a pipeline need to be installed inside the container. Coupled with devices such as a thermostat additionally equipped on the container, there will be too many devices installed on the container, which affects the appearance and is inconvenient to use.

[0003] The utility model aims at the defects that the water replenishing device and the water draining device in the prior art are relatively independent and inconvenient to use, and discloses a water changing device that is conveniently installed. Summary of the Utility Model

[0033] The water changing device is used in cooperation with a thermostat. In the water replenishing state, the water changing device sucks and conveys the external water to the thermostat through the water inlet pipeline A1, and after the thermostat regulates the temperature of the water, the water is conveyed to the container. In the drainage state, the water changing device sucks the water inside the container, so that the water inside the container is discharged through the drainage pipeline A2. The specific working process is as follows:

Under the action of the forward rotation of the peristaltic pump 5, the water is conveyed from the second end of the peristaltic pump 5 to the thermostat.

[0035] As Figure 6 shown, in the drainage state, the peristaltic pump 5 rotates reversely to generate reverse power, so that the water inside the container enters the peristaltic pump 5 through the second end of the peristaltic pump 5, and then enters the three-way valve 4 through the third end of the three-way valve 4, and then is discharged through the drainage pipeline A2 at the second end of the three-way valve 4.

[0036] The water changing device realizes the modular integrated installation of the water changing device outside the thermostat through the convenient splicing of the water changer housing 1 and the installation housing of the thermostat.

[0039] Furthermore, the connector quick-connection limiting member 7 includes a limiting seat, and limiting notches for clamping the water inlet connector and the drain connector are respectively arranged at the top of the limiting seat. The limiting notches are correspondingly arranged with the outer contours of the water inlet connector and the drain connector, and the water inlet connector and the drain connector are supported and fixed through the cooperation of the limiting notches with the bottom of the water inlet connector and the bottom of the drain connector.

[0040] Other parts of this embodiment are the same as those of Embodiment 1, so they will not be described in detail.

[0041] Embodiment 3:

[0042] A water-changing device with convenient installation, improved on the basis of Embodiment 1 or 2, as Figure 1 shown, the quick-connection part 2 includes quick-connection chutes or quick-connection ribs arranged on the left and right sides outside the water changer housing 1; further includes an installation housing 8, an installation groove for plugging and matching with the water changer housing 1 is arranged on the installation housing 8, a matching part 9 for sliding plugging with the quick-connection part 2 is arranged on the side wall of the installation groove, and a locking port 10 for correspondingly clamping with the locking mechanism 3 is arranged at the top of the matching part 9.

[0043] When quick-connection chutes are arranged on the left and right sides outside the water changer housing 1, the matching parts 9 arranged on the left and right side walls of the installation groove on the installation housing 8 are arranged as ribs for correspondingly plugging and matching with the quick-connection chutes. When quick-connection ribs are arranged on the left and right sides outside the water changer housing 1, the matching parts 9 arranged on the left and right side walls of the installation groove on the installation housing 8 are arranged as grooves for correspondingly plugging and matching with the quick-connection ribs. When the water changer housing 1 is installed in place in the installation groove, at this time, the locking mechanism 3 is correspondingly plugged with the locking port 10, and the water changer housing 1 is locked and fixed inside the installation groove through the locking mechanism 3.

[0044] Furthermore, as Figure 3And Figure 4 As shown, the locking mechanism 3 includes a pushing block 31 and a locking block 32. The pushing block 31 is slidably arranged inside the water changer housing 1 at a position above the quick-connect part 2. One end of the pushing block 31 is connected to the locking block 32. The quick-connect part 2 and the mating part 9 are slidably connected in the vertical direction, while the pushing block 31 is slidably arranged inside the water changer housing 1 at a position above the quick-connect part 2 in the horizontal direction.

By moving the dial, the pushing block 31 is driven to slide horizontally close to or away from the groove wall of the installation groove. When the pushing block 31 slides horizontally close to the groove wall of the installation groove, the locking block 32 is driven to enter the locking port 10 to lock the water changer housing 1. When the pushing block 31 slides horizontally away from the groove wall of the installation groove, the locking block 32 is driven to disengage from the locking port 10, that is, the locking of the water changer housing 1 is cancelled.

The L-shaped limiting member 33 is slidably arranged on one side of the pushing block 31, and the sliding direction of the L-shaped limiting member 33 is perpendicular to the sliding direction of the pushing block 31; a limiting space for the pushing block 31 to slide is formed between the L-shaped limiting member 33 and the inner wall of the water changer housing 1.

[0046] The L-shaped limiting member 33 is slidably arranged on one side of the pushing block 31 in the horizontal direction, and the sliding direction of the L-shaped limiting member 33 is perpendicular to the sliding direction of the pushing block 31. Specifically, inside the water changer housing 1, the pushing block 31 slides in the horizontal first direction, and a sliding groove is arranged on one side of the pushing block 31 in the horizontal second direction perpendicular to the first direction. The L-shaped limiting member 33 is slidably connected with the sliding groove. After the L-shaped limiting member 33 slides close to the pushing block 31 in place, a limiting space for the pushing block 31 to slide is formed between the L-shaped limiting member 33 and the inner wall of the water changer housing 1, thereby guiding and limiting the sliding of the pushing block 31 in the horizontal first direction to ensure that the pushing block 31 can smoothly drive the locking block 32 into the locking port 10.
