A table water purifier with a brand new design is shown in fig. 1. The desktop water purifier 10 includes a housing 11 and a water outlet nozzle 12. A spout 12 is provided on the housing 11. In order to solve the problem of secondary pollution of the pure water, the desktop water purifier 10 further comprises a first ultraviolet disinfection module 13. The first ultraviolet disinfection module 13 is arranged at one side of the water outlet nozzle 12, namely the first ultraviolet disinfection module 13 is arranged outside the shell 11. When the first ultraviolet disinfection module 13 is in an operating state, an effective disinfection area 14 is formed in a coverage area of the first ultraviolet disinfection module 13, namely on one side of the housing 11, and objects in the effective disinfection area 14 can be disinfected and sterilized. The desktop water purifier 10 is further provided with a first induction module 15 and a second induction module 16. The first sensing module 15 is used to detect whether there is a vessel in the active sterilization zone 14. If there is a vessel in the active sterilization zone 14, the first sensing module 15 generates a vessel detection signal. The first sensing module 15 outputs the vessel detection signal to the control module. The control module receives the utensil detection signal, generates and outputs a first switch signal to the first ultraviolet disinfection module 13, and drives the first ultraviolet disinfection module 13 to start working, so that terminal water and utensils flowing out of the water outlet nozzle 12 are sterilized, and the water safety is ensured. The second sensing module 16 is used to detect whether a human body is present in the effective disinfection area 14. If there is a human body in the effective disinfection area 14, the second sensing module 16 generates a human body detection signal, and the second sensing module 16 outputs the human body detection signal to the control module. The control module receives the human body detection signal, generates and outputs a second switch signal to the first ultraviolet disinfection module 13, and drives the first ultraviolet disinfection module 13 to stop working. The desktop water purifier 10 provided by the embodiment can ensure the sanitation of water and drinking water environment, and can simultaneously realize water sterilization and vessel sterilization, and especially ensure the water safety of drinking water in the seasons where bacteria and viruses are easy to be sent out. The first sensing module 15 for detecting the vessel may be implemented by a hall sensor or a pressure sensor disposed in the cup, or may be implemented by a set of infrared sensors disposed on the housing 11 and having a signal transceiving function. The second sensing module 16 for detecting a human body may be implemented by an infrared sensor. The first uv disinfection module 13 is preferably a uv lamp. The first uv disinfection module 13 is arranged below the outlet nozzle 12 to form an effective disinfection area 14 below the outlet nozzle 12. The control module (not shown in the figure) is preferably a single chip with multiple I/O interfaces or other integrated circuits capable of implementing the same function, and the specific model of the control chip is not limited herein.

To prompt the user of the disinfection process, a display module (not shown) is also provided on the housing 11. When the control module receives the utensil detection signal, the warning signal is generated and output to the display module, and the user is prevented from taking the utensil when the set sterilization time is not reached. The display module can be an LCD display screen, an LED display screen or a human-computer interaction interface of the water purifier.

The internal water circuit structure of the desktop water purifier 10 will be further described with reference to fig. 2 and 3. As shown in fig. 3, the desktop water purifier 10 in this embodiment includes a raw water tank 17, and a water outlet 19 of the raw water tank 17 is sequentially connected to a first water pump 24, a front composite filter element 25, a reverse osmosis filter element 26, a rear filter element 27, a pure water tank 22, a second water pump 28, a heater 29, and a water outlet nozzle 12. Wherein the reverse osmosis filter element 26 is communicated with the concentrated water return opening 18 of the raw water tank 17, and a flushing electromagnetic valve 30 is arranged between the reverse osmosis filter element 26 and the concentrated water return opening 18. A second ultraviolet sterilization module 23 is provided in the pure water tank 22 to sterilize the pure water stored in the pure water tank.

In the raw water tank 17 designed specifically in this embodiment, the water outlet 19 and the concentrate return port 18 are both provided on the bottom wall of the raw water tank 17. A separation plate 20 is arranged between the water outlet 19 and the concentrated water return port 18, one end of the separation plate 20 is fixed on the bottom wall of the raw water tank 17, and the other end of the separation plate 20 extends upwards until a gap is formed between the other end and the top wall of the raw water tank 17. Preferably, the height of the gap is less than half of the height of the partition plate 20, that is, the partition plate 20 is used to form a semi-closed raw water chamber and a concentrated water chamber which are communicated at the upper part in the raw water tank 17. Preferably, the concentrate return port 18 protrudes from the bottom wall of the raw water tank 17, and extends upward from the bottom wall of the raw water tank 17 to form a tubular end, and the circumferential wall of the end is formed with at least one overflow hole. An end cover 21 is formed above the end part, and the end cover 21 is provided with side edges which are symmetrically bent downwards and extend. The side edge is located outside the end of the concentrate return opening 18, so that the side edge and the circumferential wall of the end together enclose an overflow channel. The concentrated water flowing in from the end part flows into the bottom of the raw water tank 17 through the end part, the overflow hole and the overflow channel, so that the concentrated water flowing back to the raw water tank 17 does not directly rush out upwards to be mixed with the raw water, but flows back to the bottom of the tank in a directional mode. Because the density of the returned concentrated water is high, in the process of gradually increasing the water level, the relatively clean water with low density is positioned above and gradually enters the raw water tank, while the relatively turbid water with high density is positioned below and gradually deposits, and only the water with better water quality flows through the reverse osmosis membrane filter element. Thereby effectively utilizing the concentrated water, simultaneously improving the service life of the reverse osmosis membrane to the maximum extent, reducing the TDS value of the pure water and ensuring that the drinking water is more sanitary.

The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or that equivalents may be substituted for elements thereof; such modifications and substitutions do not depart from the spirit and scope of the present invention, which is claimed.
