[0002] With the improvement of teaching quality and teaching requirements, especially in laboratories with a wide variety of teaching equipment, laboratory teaching equipment such as sink cabinets are also gradually improved. Test tubes, beakers and other experimental utensils are cleaned by sinks. A large number of experiments will be carried out in the laboratory, and the sink will be used very frequently, so the sink cabinet plays a very important role in the laboratory.

[0003] The sink cabinets in the prior art usually have downward drainage. Before the laboratory is renovated, water pipes need to be pre-buried on the ground to connect the sink cabinet. The pre-buried water pipes are fixed, and the sink cabinet cannot be moved if it wants to keep connected. This makes the layout of the sink cabinet in the laboratory fixed. If the sink cabinet is moved, the water pipes need to be pre-buried again, which will take a lot of time and increase the cost. In addition, the frequent use of the sink also has great requirements on the drainage efficiency of the sink. Therefore, a sink cabinet that is easy to move and has a fast drainage speed is proposed.

Therefore, the directions and positions used are used to explain and understand the present invention, but not to limit the scope of protection of the present invention.

[0023] like Figures 1 to 5 As shown, an embodiment of the utility model is a fast-draining sink cabinet, comprising a cabinet body 1 and a sink 2 arranged on the top of the cabinet body 1, a faucet 3 is installed on the sink 2, the faucet 3 is connected to a water inlet pipe 4, a drain port 5 is provided at the bottom of the sink 2, a water pump 6 is connected to the bottom of the drain port 5, an end of the water pump 6 away from the drain port 5 is connected to a water outlet pipe 7, an end of the water inlet pipe 4 away from the faucet 3 passes through the top of the sink 2 and extends to the outside, an end of the water outlet pipe 7 away from the water pump 6 passes through the top of the sink 2 and extends to the outside, the water pump 6 is also connected to a liquid level sensor 8, the liquid level sensor 8 is used to detect the water level of the drain port 5 and send an electrical signal to the water pump 6, and the water pump 6 starts or stops drainage through the electrical signal of the liquid level sensor 8.

[0024] The beneficial effects of such a configuration are as follows: in the utility model, a water outlet pipe connected to the water sink passes through the top of the water sink and extends to the outside, and the water outlet pipe is connected to a water pump. The water outlet pipe provides power for pumping water through the water pump to achieve upper drainage, and the upper drainage can be connected to an exposed water pipe. The exposed water pipe is convenient for replacing the joint position connected to the water sink cabinet, so that the water sink cabinet is also convenient to move. The layout of the laboratory sink cabinet can be adjusted according to classroom needs. Through the liquid level sensor and the water pump, when the liquid level sensor senses that there is water in the water sink, it sends an electrical signal to the water pump, and the water pump starts working immediately, which not only saves electricity consumption but also speeds up the drainage speed.

[0025] It is further configured that the outer wall of the drain outlet 5 is provided with a mounting groove 9 for installing the liquid level sensor 8, and mounting plates 10 extend toward the middle from both side edges of the mounting groove 9. The liquid level sensor 8 is installed in the mounting groove 9 and connected to the mounting plate 10 via fasteners.

[0026] The beneficial effects of this arrangement are as follows: the liquid level sensor is non-contact and is installed in the mounting groove on the outer wall of the drain outlet. The test will produce toxic substances, strong acids, strong alkalis and various liquids discharged into the sink. The non-contact liquid level sensor can detect the liquid level of the sink without contacting the liquid. It is more suitable for laboratory sink cabinets and is firmly fixed to the mounting plate through fasteners.

[0027] It is further provided that an interface 11 threadedly connected to the water pump 6 extends from the bottom of the drain outlet 5, and a check assembly is provided on the interface 11, and the interface 11 is connected or blocked by the check assembly.

[0028] The beneficial effects of such a configuration are as follows: the upper drainage structure and the check assembly can prevent the water in the outlet pipe from flowing back into the sink.

[0029] It is further provided that the check assembly includes a connecting pipe 12 and an end cover 13 cooperating with the connecting pipe 12, the connecting pipe 12 is threadedly connected to the interface 11, the connecting pipe 12 is penetrated by a plurality of through holes 14, a cavity 15 is opened in the middle of the connecting pipe 12, a connecting rod 16 is extended from the end cover 13, one end of the connecting rod 16 away from the end cover 13 extends to the inside of the cavity 15, and a butt ring 17 is extended radially, one end of the connecting rod 16 located in the cavity 15 is covered with a spring 18, a retaining ring 19 is extended from the edge of the cavity 15, one end of the spring 18 abuts against the butt ring 17 and the other end abuts against the retaining ring 19, and the end cover 13 is slidably connected to the connecting pipe 12 through the spring 18.

[0030] The beneficial effects of such a configuration are as follows: the end cover is used to block or connect the through hole of the connecting pipe. When connected, water from the sink can flow to the water pump through the through hole. The connecting rod of the end cover slides back and forth in the connecting pipe through a spring, and self-sealing is achieved by spring reset. When there is no water, the end cover blocks the through hole. When there is water in the through hole, the water pressure drives the end cover to move and connect the water pump to achieve drainage. When water from the water pump flows back to the interface, the end cover presses against the connecting pipe under the pressure of the reflux water to prevent backflow. It has the advantages of exquisite structure and stability.

[0031] It is further configured that the outer wall of the retaining ring 17 is in contact with the inner wall of the cavity 15 , and the inner wall of the retaining ring 19 is in contact with the outer wall of the connecting rod 16 .

[0032] The beneficial effects of such a configuration are as follows: the fit between the retaining ring and the cavity makes the end cover and the connecting pipe coaxial, and the reciprocating movement is smoother; the fit between the retaining ring and the connecting rod prevents water from entering the cavity and affecting the spring.

[0033] It is further configured that a sleeve 20 extends from the outer edge of one end of the connecting pipe 12 close to the end cover 13, and an inclined surface 21 is provided at the end of the sleeve 20. The angle between the inclined surface 21 and the outer wall of the connecting pipe 12 is an acute angle, and the end cover 13 and the sleeve 20 form a plug-in fit.

[0034] The beneficial effects of such a configuration are as follows: the sleeve and the end cover form a plug-in fit, which improves the sealing performance; the inclined surface guides the end cover to slide into the sleeve, and the plug-in fit is faster and more stable.

[0035] It is further provided that a sealing ring 22 is provided at the matching position between the connecting pipe 12 and the end cover 13 .

[0036] The beneficial effect of such arrangement is as follows: the sealing effect between the connecting pipe and the end cover is further enhanced by the sealing ring.

[0037] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
