The abutting strips 211 extend in the vertical direction, and the horizontal width gradually increases from bottom to top, so that when the raw water tank 2 is installed, the abutting strips 211 and the side walls of the tank groove 111 are gradually tightly abutted, thereby improving the connection stability of the raw water tank 2 and the tank seat 11.

[0044] The side wall of the tank seat 11 extending in the vertical direction is provided with a positioning seat 112 which is fixed to the tank seat 11 by means of bolts or welding. The side wall of the raw water tank 2 has a positioning groove 22 which is inserted into the positioning seat 112 in a matching mode. The positioning groove 22 extends in the vertical direction, and the positioning groove 22 is in a V-shaped groove with the opening downward in the vertical direction. The side walls of the positioning seat 112 and the positioning groove 22 have the same change trend, and when the positioning seat 112 abuts at the top of the positioning groove 22, the opposite side walls of the positioning seat 112 and the inner walls of the positioning groove 22 are in close contact.

[0045] Referring to Figure 4 and Figure 5 , a sealing structure is arranged between the tank seat 11 and the raw water tank 2, and the sealing structure realizes the communication or sealing of the tank seat 11 and the raw water tank 2. The sealing structure comprises a first sealing valve 23 arranged on the raw water tank 2 and a second sealing valve 12 arranged on the direct drinking machine shell 1.

[0046] The raw water tank 2 is provided with a first sealing seat 24 for installing the first sealing valve 23, and the first sealing valve 23 comprises a first valve body 231 which is slidably installed on the first sealing seat 24, a first elastic member 232, and a first valve core 233 arranged on the first valve body 231.

The first elastic member 232 is sleeved on the first valve column 2311, and the two ends thereof are fixed with the first sealing seat 24 and the first valve body 231 respectively. The first elastic member 232 is a compression spring, and in the normal state, the first valve core 233 seals and covers the through hole of the first sealing seat 24, thereby ensuring the sealing of the bottom of the raw water tank 2 and the outside.

[0047] The direct drinking machine shell 1 has a second sealing seat 13 for installing a second sealing valve 12, the second sealing valve 12 comprising a second valve body 121, a second elastic element 122 and a second valve core 123.

The outer side wall of the second sealing seat 13 has a limiting ring groove 131 for limitingly installing the second sealing part 142. The raw water tank body 2 is integrally provided with a positioning ring 25 at the bottom of the first sealing seat 24, which is used for being inserted between the pressing ring 113 and the second sealing part 142. The outer diameter of the positioning ring 25 is smaller than the inner diameter of the pressing ring 113, and there is a gap between the bottom of the positioning ring 25 and the top of the first sealing part 141. The side wall of the second sealing part 142 has a sealing convex ring 1421 abutting the inner side wall of the positioning ring 25. In the embodiment, the second sealing part 142 has two sealing convex rings 1421 in the height direction. The abutment between the sealing convex ring 1421 and the inner side wall of the positioning ring 25 and the abutment between the pressing ring 113 and the first sealing part 141 realize double sealing, which reduces the probability of foreign matter entering the second sealing seat 13 from the outside.

[0051] Referring to Figure 4 and Figure 6The direct drinking machine is provided with two sets of sealing structures, and the two sets of sealing structures are arranged at intervals along the length direction of the bottom wall of the raw water tank body 2. The two sets of sealing structures are defined as a first sealing structure and a second sealing structure respectively. The first sealing structure is in communication with the input end of the filter element 31, and the second sealing structure is in communication with the output end of the waste water element 32. The raw water tank body 2 is provided with a partition plate 26 between the first sealing structure and the second sealing structure, and the partition plate 26 divides the bottom cavity of the raw water tank body 2 into a left chamber 27 and a right chamber 28. The first sealing structure is located in the right chamber 28, and the second sealing structure is located in the left chamber 27.

[0052] The structures of the first sealing structure and the second sealing structure are consistent as a whole. The difference between the two sealing structures is that the first sealing seat 24 of the first sealing structure further extends upward at the top to be provided with an abutting convex ring 241. The first sealing structure is provided with a second filter element 7. The second filter element 7 is inserted and installed in the first sealing seat 24, and the second filter element 7 comprises a filter shell 71 and filter cotton 72 installed in the filter shell 71.

[0053] The bottom of the filter shell 71 is provided with an insertion hole 711 matched with the first sealing seat 24. The filter shell 71 is provided with a sealing gasket 712 on the top wall in the insertion hole 711. The abutting convex ring 241 abuts against the sealing gasket 712, so as to realize the sealing installation of the first sealing seat 24 and the second filter element 7. The height of the partition plate 26 is higher than the top surface of the second filter element 7, and the raw water tank body 2 is further provided with a low water level sensor in the right chamber 28.

[0054] The implementation principle of the RO installation-free direct drinking machine for heating and refrigeration is that the sealing structure realizes the communication or sealing of the raw water tank body 2 and the filter assembly 3. When the raw water tank body 2 and the tank seat 11 are fixed and inserted, the first valve body 231 and the second valve body 121 correspondingly abut against each other, and the two are pushed against each other. The first valve core 233 moves upward, and the second valve core 123 moves downward, so that the first sealing valve 23 and the second sealing valve 12 are in communication with each other. When the raw water tank body 2 is removed, the first valve body 231 and the second valve body 121 are automatically reset under the action of the first elastic element 232 and the second elastic element 122 respectively, so that the first valve core 233 and the second valve core 123 respectively seal the corresponding through holes.

[0055] The user pours tap water into the raw water tank, starts the direct drinking machine, the filter element 31 draws the tap water in the right chamber 28, and the filtered pure water is delivered to the purified water tank 4. The waste water generated by filtration is delivered to the left chamber 27 through the waste water element 32 and the second sealing structure. The waste water contains a large amount of soluble inorganic salts, organic matter and other impurities, so that the waste water automatically sinks in the left chamber 27, and the probability of the waste water entering the right chamber 28 is reduced through the partition plate 26.

[0056] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
