Referring to Fig. 4 and Fig. 5, in the present invention, the housing 23 includes an accommodating chamber 231 and a water outlet part 232, the central shaft 222 and blades 223 are placed in the accommodating chamber 231, and the water outlet part 232 is a spray arm. The casing 23 can be integrally formed or connected to each other. Preferably, in the present utility model, the casing 23 is integrally formed. The top opening of the accommodating cavity 231 is formed as the water inlet 233 of the water pump, while the bottom opening of the accommodating cavity 231 is adapted to the chassis 221 , and the chassis 221 closes the bottom of the accommodating cavity 231 . The water inlet 233 at the top of the accommodating cavity 231 is provided with a filter plate 24, and the filter plate 24 and the housing 23 are integrally formed to filter the water entering the accommodating cavity 231 from the water inlet 233, and the water tank body 1 The dirt inside is isolated from the impeller 22 and the casing 23, so as not to cause blockage.

A water outlet 234 is formed on the side wall of the accommodating chamber 231 at a position below the filter plate 24 , which communicates with the water outlet component 232 , so that the water entered by the water inlet 233 of the accommodating chamber 231 is pumped out to the water outlet 234 through the impeller 22 , into the water outlet component 232 . That is to say, in the present invention, the water inlet 233 is formed above the impeller 22 , and the water outlet 234 is formed on the side of the impeller 22 .

The water outlet part 232 is formed by fastening the upper bottom case 235 and the lower bottom case 236, and the space between the upper bottom case 235 and the lower bottom case 236 forms a flow distribution channel 237, and there is at least one flow distribution channel 237, which is preferred in the utility model It includes three distribution channels 237, and the distribution channels 237 are H-shaped as a whole, wherein the horizontal distribution channel 237 in the middle is adjacent to and communicates with the water outlet 234, and the vertical distribution channels 237 on both sides are connected to the horizontal ones respectively. The distribution channels 237 communicate with each other. Each distribution channel 237 includes opposite first sidewalls 2371 and second sidewalls 2372 . Thus, the connection between the horizontal distribution channel 237 and the water outlet 234 , and the connection between the vertical distribution channel 237 and the horizontal distribution channel 237 are the distribution ports 2373 formed by opening on each of the first side walls 2371 .

The top surface of the upper bottom shell 235 is provided with a plurality of water spray holes 238, the number, shape and size of the water spray holes 238 can be set according to needs, and the directions of the water spray holes 238 can also be different respectively, thereby forming a better spraying effect. Effect. The water spray hole 238 communicates with the distribution channel 237, sprays the water pumped by the impeller 22 from the distribution channel 237, and sprays and cleans the fruits and vegetables to be cleaned in the sink body 1.

Because the water inlet of the open water pump 2 is positioned at the top of the impeller 22 (upper water intake), and the water outlet 234 is positioned at the side of the impeller 22, that is, the height of the water outlet 234 is approximately the same as the height of the blade 223, therefore, the impeller 22 need not start from the bottom. To draw the water upward, the blade 223 only needs to adopt a relatively simple straight blade structure, which not only has a simple structure, but also facilitates the processing.

In order to prevent the water outlet part 232 from moving relative to the impeller 22, in the present utility model, the water outlet part 232 (spray arm) is connected and fixed with the tank body 1 . Preferably, in order to facilitate the installation and disassembly of the water outlet part 232, the water outlet part 232 and the sink body 1 adopt a detachable, preferably snap fit manner.

Through the first buckle 12 and the second The cooperation of the two buckles 25 makes the water outlet part 232 snap fit with the bottom of the water tank body 1 to complete the installation of the water outlet part 232, and at the same time facilitate the disassembly of the water outlet part 232 to be taken out from the water tank body 1.

When the open water pump 2 is working, the motor 21 drives the vane 223 to rotate, and the water enters the accommodating chamber 231 after passing through the filter plate 24. The flow direction can be referred to the direction indicated by the straight arrow in Fig. 5. The water flow is ejected from the water spray hole 238 into the sink body 1, and the fruits and vegetables in the sink body 1 are cleaned. The cleaning is convenient and clean, and there is no cleaning dead angle.
