[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example: Figure 1-5As shown, the high-precision water-discharging infant drinking water machine includes a shell 1, a water storage barrel 2, a vane pump 3 and a water outlet pipe 4. The shell 1 has a accommodating chamber 101. The water storage barrel 2 is accommodated in the accommodating chamber 101 and is spaced from the bottom of the accommodating chamber 101 to form an assembly space 102. The vane pump 3 is accommodated in the assembly space 102 and is connected to the water storage barrel 2. The water outlet pipe 4 extends upward from the vane pump 3 to one side of the top of the water storage barrel 2 and partially extends out of the shell 1. The water outlet pipe 4 is a metal pipe. The water outlet pipe 4 has a straight pipe section 401. The straight pipe section 401 extends from one side of the bottom of the water storage barrel 2 to one side of the top of the water storage barrel 2. The straight pipe section 401 is in a straight line shape. The vane pump 3 is a water pump used to pump water in the water storage barrel 2 into the water outlet pipe 4. The present embodiment provides a high-precision water outlet infant drinking machine to solve the problem that the silicone tube connecting the diaphragm pump and the water outlet pipe is arranged in a curved manner in the shell, the water body has a large resistance when flowing in the silicone tube, the water outlet is blocked, and the water output of the drinking machine deviates from the preset value and the water outlet accuracy is low. The problem is mainly solved by arranging the vane pump 3 in the assembly space 102 formed by the water storage barrel 2 and the bottom of the accommodating chamber 101, and arranging the water outlet pipe 4 connected to the vane pump 3 to extend from bottom to top to one side of the top of the water storage barrel 2. Compared with the diaphragm pump, the connection structure of the vane pump 3 and the housing 1 is simple, so the vane pump 3 can be arranged in the assembly space 102 formed by the water storage barrel 2 and the bottom of the accommodating chamber 101 (that is, arranged at the lower end of the housing 1). Since the vane pump 3 is arranged in the assembly space 102 formed by the water storage barrel 2 and the bottom of the accommodating chamber 101, the water outlet pipe 4 connected to the water storage barrel 2 can be arranged to extend from bottom to top to the top side of the water storage barrel 2, and has a straight pipe section 401 extending from the bottom side of the water storage barrel 2 to the top side of the water storage barrel 2 (no need to avoid the middle part of the water storage barrel 2). The related parts or connecting structures of the diaphragm pump are arranged in a curved and extended manner). Since the water outlet pipe 4 has a straight pipe section 401 extending from the bottom side of the water storage barrel 2 to the top side of the water storage barrel 2, the resistance to water flow is reduced and the water outlet accuracy is high. Since the water outlet pipe 4 is a metal pipe, the water outlet resistance of the metal pipe is smaller than that of the silicone pipe, and the metal pipe is a rigid material and will not expand or compress to affect the water outlet accuracy when the water pump pumps water, thereby making the water outlet accuracy higher. Since the vane pump 3 is a gravity-type water pump, it has a good pumping effect when used in conjunction with the water outlet pipe 4 extending up and down.

[0026] In the embodiment of the utility model, the water storage barrel 2 is a cylindrical straight barrel, and the straight pipe section 401 is in a straight line and parallel to the axis of the water storage barrel 2. Since the straight pipe section 401 is in a straight line and parallel to the axis of the water storage barrel 2, the water outlet channel formed by the water outlet pipe 4 has a longer straight section, the water outlet resistance is small, and the water outlet precision is high.

[0027] In the embodiment of the utility model, the water outlet pipe 4 has a lower connecting pipe section 402, a straight pipe section 401 and an upper connecting pipe section 403.

The lower connecting pipe section 402 is an L-shaped pipe, and the upper connecting pipe section 403 is a U-shaped pipe. Since the lower connecting pipe section 402 connecting the straight pipe section 401 and the vane pump 3 is an L-shaped pipe, and the upper connecting pipe section 403 connecting the upper end of the straight pipe section 401 is a U-shaped pipe, the upper and lower sections of the water outlet pipe 4 are composed of multiple sections of straight pipes. Although there are corners, the number of corners is small and the angle is large, the water outlet resistance is small, and the water outlet precision is high. In addition, since the lower connecting pipe section 402, the straight pipe section 401 and the upper connecting pipe section 403 are detachably fixedly connected, assembly is convenient.

[0028] In the embodiment of the utility model, one end of the straight pipe section 401 is inserted into the lower connecting pipe section 402 and the other end is inserted into the upper connecting pipe section 403. The outer ring of the lower connecting pipe section 402 is provided with a lower locking spring (not marked in the figure) to make its inner wall of the pipe press against the outer wall of the pipe of the straight pipe section 401, and the outer ring of the upper connecting pipe section 403 is provided with an upper locking spring (not marked in the figure) to make its inner wall of the pipe press against the outer wall of the pipe of the straight pipe section 401. The above arrangement makes the lower connecting pipe section 402, the straight pipe section 401 and the upper connecting pipe section 403 connected firmly and with strong sealing performance.

[0029] In the embodiment of the utility model, the upper connecting pipe section 403 partially extends out of the housing 1, and a water outlet 404 is formed at one end of the upper connecting pipe section 403 extending out of the housing 1. The housing 1 is provided with a push switch 5 electrically connected to the vane pump 3 above the upper connecting pipe section 403.

[0030] In the embodiment of the utility model, a bracket 6 for supporting the water storage barrel 2 is provided in the assembly space 102, and a slot 601 is formed on the bracket 6 for the lower end of the straight pipe section 401 to be inserted. Since the slot 601 for fixing the lower end of the straight pipe section 401 is formed on the bracket 6 for supporting the water storage barrel 2, the water outlet pipe 4 has good assembly stability, and the shaking is prevented from affecting the water outlet accuracy.

[0031] In the embodiment of the utility model, the accommodating chamber 101 is provided with a stopper 7 on its wall that is plugged into the upper end of the straight pipe section 401. Since the accommodating chamber 101 is provided with a stopper 7 on its wall that is plugged into the upper end of the straight pipe section 401, the water outlet pipe 4 has good assembly stability to prevent its shaking from affecting the water outlet accuracy.
