Example 1

A differential waterway water purifier without a built-in water tank 12 as shown in fig. 1 to 6, comprising: a housing 1, wherein the housing 1 is provided with: the device comprises a first water pump 2, a filtering device 3, a first one-way valve 4, a second one-way valve 5, a pressure reducing device 6, a buffer hose, a second water pump 7, a heating device 8, a first water outlet 9 and a control device 10 which can be connected with an external water source; the output end of the first water pump 2 is communicated with the input end of the filtering device 3; the output end of the filtering device 3 is respectively communicated with the input end of the first one-way valve 4 and the input end of the second one-way valve 5; the output end of the first one-way valve 4 is communicated with the input end of the pressure reducing device 6; the output end of the second one-way valve 5 is communicated with the input end of the filtering device 3; the output end of the pressure reducing device 6 is communicated with one end of a buffer hose, and the other end of the buffer hose is communicated with the input end of a second water pump 7; the output end of the second water pump 7 is communicated with the input end of the heating device 8, and the output end of the heating device 8 is communicated with the first water outlet 9; the first water pump 2, the second water pump 7, the heating device 8 and the first water outlet 9 are all electrically connected with the control device 10.

In the actual use process, the traditional built-in water storage tank 12 is used for containing filtered purified water, and heating devices such as heating pipes are arranged in some built-in water storage tanks 12 and used for continuously heating the purified water in the water storage tanks 12, so that people can directly output hot water when the hot water is needed. However, in this water purifier structure, on one hand, the water in the built-in water tank 12 needs to be continuously and repeatedly heated, which has a certain influence on the water quality, and the internal water tank 12 is in a high temperature state for a long time, which can cause bacteria breeding and influence the health of users. The present application provides a water purifier without a built-in water tank 12 in order to solve the above-mentioned problems. The first pump 2 is used to pump water from an external water source, specifically, the external water source usually has two sources, one is unpowered water such as barreled mineral water, and the other is powered water flow such as water in a tap water pipe. In order to enable unpowered water to smoothly pass through the filtering device 3, the equipment is internally provided with the first water pump 2, the input end of the first water pump 2 is connected with an external water source, so that power can be provided for the external unpowered water, the flow can be limited by the excessive water flow, and the equipment is prevented from being damaged by the excessive water flow. The water output by the first water pump 2 enters the filtering device 3 for filtering, the filtered water is required to be conveyed into the pressure reducing device 6 for pressure reduction, the water flow passing through the pressure reducing device 6 is not subjected to the action of the thrust pressure of the first water pump 2, the water flow is changed into unpowered water flow, the pressure reducing device 6 is connected with the buffer hose, the unpowered water flow slowly descends in the buffer hose and flows to the input end of the second water pump 7. In the device, the second water pump 7 is used for carrying out secondary acceleration on the unpowered water flow so as to enable the unpowered water flow to flow upwards, and the unpowered water flow passes through the heating device 8 and flows to the water outlet. In order to avoid that the service life is affected by the idling of the water pump, the flow rate of the second water pump 7 is smaller than the flow rate of the first water pump 2, so that a sufficient amount of water can enter the device, but the flowing water can be ensured to be stable.

Because the flow of the second water pump 7 is smaller than that of the first water pump 2, the water which is multiprocessed by the first water pump 2 needs to be split, that is, three-way is used to disperse the water which is output by the filtering device 3, on one hand, the first one-way valve 4 is connected with the input end of the pressure reducing device 6, and on the other hand, the second one-way valve 5 is connected with the input end of the filtering device 3 (in the application, the output end of the second one-way valve 5, the input end of the filtering device 3 and the output end of the first water pump 2 are also connected by the three-way), so that redundant water can flow into the filtering device 3 again after passing through the second one-way valve 5, no damage is caused to a subsequent waterway because of overlarge flow, and the second one-way valve 5 has the functions of avoiding water flow backflow, so that unfiltered water which is output by the first water pump 2 directly enters the pressure reducing device 6.

In summary, the buffer hose and the pressure reducing device 6 are adopted to replace the water storage tank 12 in the water purifier, when hot water is needed, the heating device 8 is correspondingly controlled to heat, hot water can flow out from the water outlet, and when hot water is needed, filtered cold water can be directly output.

Specifically, the connecting seat 11 is of a hollow structure, and is mainly used for 'hot plug water tank 12', that is, the connecting seat 11 can be communicated with the water inlet 111 of the water purifier, so that the input end of the first water pump 2 is communicated with the water outlet on the connecting seat 11, the water inlet 111 on the connecting seat 11 is positioned at the top and can be communicated with the water outlet at the bottom of the water tank 12, the water outlet at the bottom of the water tank 12 is of a quick-release design, that is, when the water level in the water tank 12 is low, the water tank 12 can be directly pulled down, and water in the water tank 12 cannot flow out from the bottom, which belongs to other patent related contents and is not repeated in the application.

Further, the method further comprises the following steps: the electromagnetic valve 13 can be connected with an external water source, and the output end of the electromagnetic valve 13 is communicated with the input end of the first water pump 2; the solenoid valve 13 is electrically connected to the control device 10. Specifically, the electromagnetic valve 13 is mainly used for turning off a power water source, and if the water inlet 111 of the water machine is directly connected with a tap water pipe, the water pressure in the tap water pipe can continuously influence the waterway inside the water machine. Aiming at the situation, the electromagnetic valve 13 is arranged in front of the water pump, so that the continuous stress of an internal waterway can be avoided, and the service life of the equipment is prolonged.

Further, the device also comprises a water level sensing device 14; the input end of the water level sensing device 14 is communicated with the output end of the first water pump 2, and the output end of the water level sensing device 14 is communicated with the input end of the filtering device 3; the height of the water level sensing device 14 is higher than that of the first water pump 2, and the water level sensing device 14 is also electrically connected with the control device 10.

Further, the filtering device 3 comprises a fixing seat 31, a filter element shell 32 and a filter element; the fixed seat 31 is fixedly arranged in the shell 1, and the filter element shell 32 is detachably connected with the fixed seat 31; the cartridge is received within the interior of the cartridge housing 32; the input end and the output end of the filtering device 3 pass through the fixing seat 31 and are inserted on the filter element shell 32. Specifically, the filtering device 3 is in a pluggable form, the filter element base and the filter element shell 32 are detachably connected, so that the filter element can be conveniently replaced regularly without deeply disassembling the water purifier.

Further, a handle 33 is fixedly arranged at the top of the filter element shell 32.

Further, a touch screen 15 is further arranged on the housing 1; the touch screen 15 is electrically connected with the control device 10, and the first water outlet 9 is arranged in the touch screen 15.
