[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0026] Embodiment: as attached Figures 1-5The illustrated unidirectional water-discharge washing pump for multiple vehicle models includes a pump body 1. The pump body 1 has two identical water-discharge guide columns 2. The washing pump also includes a water-discharge device 3, which includes a connector body 4. The connector body 4 has a water-discharge channel 5 inside, and the water-discharge channel 5 passes through one end of the connector body 4, i.e., one end of the connector body 4 is closed, and the other end is open as the outlet of the water-discharge channel 5. The side of the connector body 4 has two docking parts 6, which are respectively connected to the corresponding water-discharge guide columns 2. The side of the connector body 4 has a through hole 12 at the inner end of one of the docking parts 6 for connecting the water-discharge guide column 2 and the water-discharge channel 5. That is, one inner end of the two docking parts 6 is connected to the water-discharge channel 5, and the other is blocked from the water-discharge channel 5. The through hole 12 can be set at the inner end of any docking part 6. The pump body 1 with a dual-outlet structure can be used. When the water outlet device 3 is assembled, a unidirectional (left-hand and right-hand) structure can be achieved, increasing the speed of assembly. Since the two water outlet guide pillars 2 have the same structure, the two docking parts 6 are designed to match the two water outlet guide pillars 2. That is, the structures of the two docking parts 6 are also the same. By changing the assembly method, bidirectional water outlet can be changed to unidirectional water outlet (left-hand or right-hand), eliminating the need for multiple molds for separate injection molding. This structure simplifies the injection molding and installation process and improves production efficiency.

[0027] The docking part 6 can be a tank or a sleeve structure. The docking part 6 is connected to the corresponding water outlet guide column 2 by a plug-in connection.

[0028] In this embodiment, as shown in the appendix Figure 3 As shown, the docking part 6 includes a docking sleeve 7, which is sleeved on the outer periphery of the corresponding water outlet guide post 2. The outer edge of the end of the water outlet guide post 2 is provided with a rounded chamfer, and the two can be tightly fitted by interference fit. The insertion and engagement of the water outlet guide post 2 and the docking sleeve 7 can achieve quick assembly of the two.

[0029] As attached Figures 3-5 As shown, the inner circular surface of the docking sleeve 7 is provided with an annular boss 8, and the outer circular surface of the water outlet guide post 2 is provided with an annular groove 9 that matches the annular boss 8. The annular boss 8 on the docking sleeve 7 matches the annular groove 9 on the water outlet guide post 2, thereby achieving a locking and sealing between the docking sleeve 7 and the water outlet guide post 2.

[0030] As attached Figures 3-5 As shown, a limiting step 10 is provided on the outer circular surface of the water outlet guide post 2. When the docking sleeve 7 is fitted onto the outer circumference of the corresponding water outlet guide post 2, the limiting step 10 abuts against the end of the docking sleeve 7 to limit its stroke. Limiting the stroke of the docking sleeve 7 facilitates the precise engagement of the annular boss 8 on the docking sleeve 7 and the annular groove 9 on the water outlet guide post 2, and prevents relative displacement between the two due to accidental thrust, resulting in better structural stability.

[0031] The mating sleeve 7 and the connector body 4 are integrally formed. The mating sleeve 7 and the connector body 4 are manufactured by integral injection molding, which is not only convenient to process, but also has high structural strength.

[0032] As attached Figure 5 As shown, a reinforcing plate 11 is provided on the outer side of the connector body 4. The reinforcing plate 11 is also integrally injection molded with the connector body 4. Both ends of the reinforcing plate 11 are connected to two mating sleeves 7 respectively. The reinforcing plate 11 is provided between the two mating sleeves 7 to support the mating sleeves 7, thereby improving the strength of the mating sleeves 7 and enhancing the usability of the water outlet device 3.
