As shown in fig. 1 to 5, the present invention provides a pipeline machine including a water storage tank 10 and a housing 20. The top of the water storage tank 10 is provided with a through hole 13, the bottom of the water storage tank is provided with a water inlet 11 and a water outlet 12, the shell 20 is provided with an exhaust port, and the exhaust port is communicated with the through hole 13. Be provided with a base plate 30 in the storage water tank 10, the base plate 30 passes through sealing washer sealing connection with the inner wall of storage water tank 10 all around to with drinking water and the outside air in the storage water tank 10 isolated, avoided the drinking water contact in outside air and the storage water tank 10, thereby lead to the drinking water contaminated.

When a user receives water, the water level in the water storage tank 10 will drop, and at this time, the base plate 30 needs to drop along with the water level. If the base plate 30 does not drop along with the water level, a vacuum region is formed between the base plate 30 and the water level in the water storage tank 10 after the water level drops, and thus the drinking water cannot flow out of the water storage tank 10.

The lowering of the base plate 30 is effected by a telescopic device 40, the telescopic device 40 comprising a scissor mechanism 50 and a drive 60. The scissors mechanism 50 comprises a plurality of scissors units, each of which comprises two scissors rods 51 crossing each other, and the two scissors rods 51 are hinged at the crossing. One end of the scissors mechanism 50 is connected to the base plate 30, and specifically, one of the scissors rods 51 of one of the scissors units in the lowest scissors mechanism 50 is hinged to the base plate 30, and the other of the scissors rods 411 is slidably connected to the base plate. Because the telescopic amount of the scissor mechanism 50 is large and the volume in the contracted state is small, the scissor mechanism does not occupy too much space in the pipeline machine. The driving device 60 is located on the outer surface of the top of the water storage tank 10, and has at least two working states, in the first working state, the driving device 60 will provide power for the scissors mechanism 50, and the scissors mechanism 50 is extended; in the second operating state, the driving device 60 does not provide power to the scissors mechanism 50 at this time, and the scissors mechanism 50 is retracted. In the second operating state, the driving device 60 does not provide power, which is beneficial to saving energy.

In one embodiment, the driving device 60 includes a connection block 61, a first pulley 62, a servo motor 63, a second pulley 64, and a conveyor belt 65. The upper end of the scissor mechanism 50 penetrates through the through hole 13 in the top of the water storage tank 10, the connecting block 61 is hinged to the upper end of the scissor mechanism 50, specifically, one scissor rod 51 in the scissor unit at the uppermost end of the scissor mechanism 50 is fixedly connected to the outer side of the water storage tank 10, and the other scissor rod 51 is hinged to the connecting block 61. First belt pulley 62 rotates the one end that sets up at storage water tank 10 top, and servo motor 63 sets up the other end at storage water tank 10 top, and second belt pulley 64 cover is established on servo motor 63's output shaft, and conveyer belt 65 is used for connecting first belt pulley 62 and second belt pulley 64, conveyer belt 65 and connecting block 61 fixed connection. The driving device 60 has a simple structure, and is convenient for practical production and installation. And the belt transmission is stable, which is beneficial to the stable descending of the scissors mechanism 50.

In one embodiment, an inner shaft 66 is fixedly sleeved on an output shaft of the servo motor 63, a pawl 661 is arranged on an end surface of the inner shaft 66 far away from the servo motor 63, a sleeve 67 is sleeved on the outer side of the inner shaft 66, and one end of the sleeve 67 is rotatably connected with the inner shaft 66. A plurality of ratchet teeth 671 are arranged on the inner wall of the other end of the shaft sleeve 67 along the circumferential direction, a second belt pulley 64 is sleeved on the outer wall, and the pawl 661 is meshed with the ratchet teeth 671.

In the first working state, the servo motor 63 drives the inner shaft 66 and the pawl 661 on the inner shaft 66 to rotate together, the ratchet teeth 671 on the shaft sleeve 67 can block the pawl 661 at this time, so that the shaft sleeve 67 rotates together, and the second belt pulley 64 is sleeved on the outer wall of the shaft sleeve 67, so that finally the second belt pulley 64 can also rotate under the driving of the servo motor 63, and further cooperate with the first belt pulley 62, the transmission belt 65 drives the connecting block 61 to move, and power is provided for the scissors mechanism 50, so that the scissors mechanism 50 moves downwards.

In the second operating state, the water in the water storage tank 10 is completely taken out by the user, and the base plate 30 is located at the lowest end of the water storage tank 10. At this time, the water purifier will replenish water into the water storage tank 10, the water level will rise to make the base plate 30 move upwards, the scissor mechanism 50 will contract, under the driving action of the connecting block 61 and the conveyor belt 65, the second belt pulley 64 will drive the shaft sleeve 67 to rotate reversely, the ratchet teeth 671 on the inner wall of the shaft sleeve 67 will rotate reversely, at this time, the pawl 661 will slip along the ratchet teeth 671, and no block will be formed between the pawl 661 and the ratchet teeth 671. Therefore, when water is replenished, the substrate 30 can be automatically moved upward only by the thrust of water without turning on the power supply of the servo motor 63 and without lifting the substrate 30 by the reverse rotation of the servo motor 63. Therefore, the power supply can be saved, and the water can not encounter extra resistance when pushing the base plate 30 to move upwards, so that the water purifier can supplement water into the water storage tank 10 conveniently.

In one embodiment, a flow sensor 121 is disposed at the water outlet 12 of the water storage tank 10, and the flow sensor 121 and the servo motor 63 are electrically connected to the controller. Due to the structure of the scissors mechanism 50, when the connecting blocks 61 move the same distance, the extension amount of the scissors mechanism 50 is not the same, so that if the rotation speed of the servo motor 63 is not changed, the base plate 30 moves downwards at a speed higher than the water level reduction speed, thereby squeezing the drinking water. Therefore, the flow sensor 121 is arranged at the water outlet 12, when the change of the flow signal received by the flow sensor 121 is larger than a certain threshold value, a signal is sent to the controller, and the controller controls the servo motor 63 to adjust the rotating speed, so that the water outlet rate of the water outlet 12 is kept stable.

In one embodiment, the interior of the substrate 30 is a hollow structure. The base plate 30 is internally hollow, so that the gravity of the base plate 30 can be reduced, the buoyancy of water to the base plate 30 can be increased, and the base plate 30 is pushed to move upwards when the excrement separating water purifier replenishes water into the water storage tank 10.

In one embodiment, the base plate 30 is attached around its periphery to the top of the tank 10 by a bellows 70. The bellows 70 moves up and down along with the substrate 30, and isolates the external air from the periphery of the substrate 30 all the time, so that the air cannot pass through the gap between the substrate 30 and the inner wall of the water storage tank 10 to contact with the drinking water, and the cleanness of the drinking water is further ensured.

In one embodiment, a filter cover 22 is disposed at the air outlet of the housing 20, the filter cover 22 is screwed to the housing 20, and a fiber filter material for adsorbing foreign substances in the outside air is disposed in the filter cover 22. The filter cover 22 can adsorb air impurities entering the water storage tank 10, so that excessive dust and air impurities are prevented from entering the pipeline machine through the exhaust port and even being accumulated on the top of the base plate 30, the sanitation of the pipeline machine is kept, and the cleaning work is reduced.
