[0028] The drawings will be described below in combination with the Figures 1-4 The present application will be described further.

[0029] The utility model provides a kind of mechanical double safety automatic water replenishing device, its structure includes water tank 1, water inlet pipe 2, water replenishing switch component 3 and lifting mechanism 4, one end of water inlet pipe 2 is connected with water tank 1, and the other end can be connected with external water delivery mechanism or water source such as pipeline, water replenishing switch component 3 includes valve 31 and floater component 32, valve 31 is located on water inlet pipe 2, floater component 32 is rotatably connected on valve 31, the rotation of floater component 32 can drive valve 31 to open or close water inlet pipe 2, effectively solve the inconvenience problem such as the labor consumption, frequent operation of traditional manual water inlet mode, improve the convenience and efficiency of water tank water replenishing, improve the use experience of customer, simultaneously, the opening and closure of water inlet pipe are controlled by the sinking and floating of floater component, eliminate the health hazard of manual water change, improve the safety of use.

[0030] Specifically, as valve 31 can be the sealing baffle that can be blocked from the radial water flow of water inlet pipe 2 with floater component 32 linkage, when floater component 32 sinks due to water tank water shortage, valve 31 gradually opens water inlet pipe, and water replenishing is carried out, normally, floater component 32 will float with water level rising, and float to horizontal state when full (reach full water level line), so that valve 31 closes water inlet pipe 2, and water replenishing stops;The specific structure and shape of valve 31 are not limited in the present application, and it can realize the closing and opening of water inlet pipe 2.

[0031] Further, the automatic water replenishing device of the present application further includes water replenishing detector to determine whether the water in the water tank is full.

[0032] In some embodiments of the present application, the water replenishing detector includes flow meter and timer arranged in the water tank or water inlet pipe to determine water full by flow and time;Or, the water replenishing detector includes electronic liquid level meter arranged in the water tank.

[0033] Specifically, when flow meter and timer are used to detect and determine whether water is full, the water inlet amount can be calculated by flow and time, and if the total water inlet amount reaches the preset water amount threshold, it is determined that the water is full;When electronic liquid level meter is used to detect and determine whether water is full, if electronic liquid level meter detects that the liquid level in water tank 1 reaches full water level line, it is determined that the water is full.

[0034] In some embodiments of the present application, floater component 32 includes connecting rod 321 and float ball 322, one end of connecting rod is connected with valve 31, and the other end is connected with float ball 322. Figures 1-2 Among them, float ball 322 is not necessarily spherical, it can also be cylindrical (such as

[0035] In order to avoid the overflow safety problem caused by the failure of the float assembly 32, the automatic water replenishing device of the present application further comprises a lifting mechanism 4 connected with the float assembly 32, which directly lifts the float assembly 32 upward when the water replenishing is completed, or lifts the float assembly 32 upward when the water replenishing is completed and the float assembly 32 fails to float upward, thus realizing double insurance protection for the automatic water replenishing device, avoiding the risk of overflow caused by the failure of the float, and improving the overall safety of the product.

[0036] Further, the automatic water replenishing device of the present application further comprises a controller connected with the water replenishing detector and the lifting mechanism through electrical connection or communication connection, etc.; when the water replenishing detector detects that the water replenishing is completed, the controller controls the lifting mechanism 4 to lift the float assembly 32 upward, or when the water replenishing detector detects that the water replenishing is completed and the float assembly 32 fails to float completely to the position to close the valve 31, the controller controls the lifting mechanism 4 to lift the float assembly 32 upward.

[0037] In some embodiments of the present application, the lifting mechanism 4 comprises a rotary motor 41 and a flexible lifting piece 42 connected with the float assembly 32, and the rotary motor 41 drives the flexible lifting piece 42 to be wound or unwound, thereby driving the float assembly 32 to move up and down.

[0038] Specifically, when the water replenishing is completed, the rotary motor 41 starts to rotate, and the flexible lifting piece 42 is wound to lift the float assembly 32, which can effectively avoid the situation that the float assembly 32 fails to float upward and the inlet pipe 2 cannot be closed; after the float assembly 32 is in a horizontal state, the rotary motor 41 reverses the rotation, and the flexible lifting piece 42 is unwound to release the flexible lifting piece 42, so that the flexible lifting piece 42 does not hinder the normal sinking of the float assembly 32 when the water tank is short of water.

[0039] In some embodiments of the present application, the lifting mechanism 4 lifts the float assembly 32 every time the water replenishing is completed.

[0040] Specifically, the timing is started when the float assembly 32 sinks and the water tank 1 starts to replenish water, the water tank 1 replenishes water according to the preset water replenishing time, and when the water replenishing is completed, the rotary motor 41 starts to wind the flexible lifting piece 42, thereby lifting the float assembly 32.

[0041] In some embodiments of the present application, the lifting mechanism 4 only lifts the float assembly 32 after detecting that the float assembly 32 fails to float upward, which generally occurs due to the presence of foreign matter or scale in the valve 31, etc., so that the float assembly 32 cannot normally float to the horizontal state.

[0042] Specifically, as when the water replenishment is completed, if the flow meter still monitors that water enters the water tank 1, it is judged that the float assembly 32 does not float completely, at this time the rotating motor 41 is started and the flexible puller 42 is wound to pull up the float assembly 32. In addition, it needs to be explained that the water tank 1 of the water replenishment device of the application has a full water level line (not shown in the figure), and the full water level line is less than the maximum volume of the water tank by a certain amount, so that when the float assembly 32 does not float completely when the water is full, the valve 31 cannot be completely closed, the water replenishment detector will detect that the water tank is still filling water, and immediately sends a command to the controller to make the controller control the pulling mechanism 4 to pull up the float assembly 32 to make it float and close the valve 31, and the water entering the water tank will not overflow from the water tank body during the process.

[0043] In some embodiments of the application, the rotating motor 41 can be arranged above the maximum water level line in the water tank 1, and the rotating motor 41 is provided with a waterproof shell, so that the rotating motor 41 can be prevented from polluting the water body, and the service life of the rotating motor 41 can be prolonged.

[0044] In some embodiments of the application, a winding device is arranged on the output end of the rotating motor 41, which facilitates the winding of the flexible puller 42, and when the rotating motor 41 drives the winding device to rotate forward and reverse, the flexible puller 42 can be wound and unwound. Optionally, the flexible puller 42 adopts a component such as a pulling rope, a pulling chain or a pulling belt which has a certain flexibility and can be wound and unwound.

[0045] The mechanical double-insurance automatic water replenishment device has the beneficial effects that: the opening and closing of the water inlet pipe are controlled by the sinking and floating of the float assembly, and the float assembly is pulled by the pulling mechanism to ensure its normal movement, the convenience and efficiency of the water tank water replenishment are improved, the problems of unhygienic traditional manual water change and overflow safety hazard of conventional automatic water replenishment devices are eliminated, and the use experience and safety of customers are greatly improved.

[0046] The above is only an embodiment of the application, and does not limit the patent range of the application, and any equivalent structure or equivalent process conversion according to the content of the application specification, or direct or indirect application in other related technical fields, are also included in the patent protection range of the application.
