[0022] The following will further illustrate the present utility model in combination with the accompanying drawings and relevant knowledge, and describe it clearly and completely. Obviously, the described applications are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0023] Referring to Figures 1-6 as shown, a plunger for waterway switching of the present utility model includes:

[0024] At least two piston units 1, which are driven by a driving structure 2 to move the piston units;

[0025] A plurality of sealing plugs 3 are arranged on the piston unit 1, and adjacent two sealing plugs are used for separating waterways;

[0026] In the present utility model, by changing the traditional single-piston mode to multiple piston units, a plurality of sealing plugs 3 are arranged on the piston unit 1, and then the piston units are driven by the driving structure 2 to move, so as to realize the switching of multiple waterways during the preparation of soft water, and there is no mutual influence, which can ensure the accuracy during the preparation of soft water.

[0027] As a further improvement, it includes three piston units 1. One end of the three piston units 1 is fixed by a connecting plate 4, and the driving structure changes the position of the piston unit by driving the movement of the connecting plate 4. Refer to Figure 3 As shown, one end of the three piston units 1 is fixed by the connecting plate 4, and then the driving structure changes the position of the piston unit by driving the movement of the connecting plate 4.

[0028] It should be specifically noted in the present utility model that the present utility model preferably uses three piston units 1, but the case of using four is not excluded.

[0029] As a further improvement, the three piston units 1 are sealed by a housing 5, and a sealing ring 6 is provided on the sealing plug. Refer to Figure 4 、 Figure 5 As shown, during use, first install the three piston units 1 in the housing, and drive the piston unit to move through the driving structure 2, so as to realize the switching of the piston position. Specifically, refer to Figure 5 As shown, three corresponding cavities 7 are provided in the housing, and the three piston units 1 are located in the three corresponding cavities 7. An opening structure 8 is provided on the side of the cavity 7, and a plurality of water inlet pipes and outlet pipes are provided on the outer shell. The specific installation method and quantity of the water inlet and outlet pipes are not limited in this application. Each opening structure 8 is correspondingly connected to a water inlet pipe 12 or an outlet pipe 13. At the same time, an opening structure 8 is also provided on the other side of the cavity 7, and the position of this opening structure 8 can be adjusted according to needs. This opening structure 8 is also connected to a water inlet pipe or an outlet pipe. Taking this structure as an example, during use, water enters from the opening structure 8 on one side, and then enters between the two sealing rings 6 of the piston unit 1 (any one of the three piston units 1 can be selected according to needs), and then flows out from the opening structure 8 on the other side. For example, it can flow into the resin layer for softening, and after softening, it can enter the water channel formed by the two sealing rings 6 of another piston unit 1, and also flows in through the opening structure 8 of the housing and flows out through the opening structure 8 on the other side of this water channel, and the soft water preparation is completed. Refer to Figure 6 As shown, that is to say, in this position situation, it is the process of preparing soft water. If the three piston units 1 are moved to another position, change a water inlet or the same water inlet, the water flows into one of the water channels formed by the two sealing rings 6 and then flows out to the brine tank from the other side. The opening structure 8 on the other side is determined according to the position of the water channel formed by the two sealing rings 6. The steps of injection (salt melting) and the realization of other functions will not be elaborated. The present utility model mainly provides a new water supply and water outlet method, using multiple piston units 1 to achieve a water channel with higher precision and a simple operation process, so as to efficiently prepare soft water.

[0030] It should be noted that the plunger for waterway switching provided by the present utility model is used to replace the traditional single-piston mode, which can realize the switching of multiple waterways and has higher precision. That is, three piston units 1 can be provided, and each piston unit 1 is provided with a sealing plug. A waterway is formed between adjacent sealing plugs. Then, by moving the piston unit 1, the waterway structure can be changed. In the present utility model, water inlet pipes and outlet pipes with different connections can be connected according to needs. Refer to Figure 5 As shown, different opening structures 8 are provided on the housing, which can realize the access and outflow of different waterways. Further, the switching of different waterways is realized by moving the piston unit 1. For example, as described above, when water enters from one side, if the water outlet channel needs to be changed, only the piston unit 1 needs to be moved. Another example is that if there are two water outlets on the other side, the water outlet channel can be selected. Specifically, it is realized by two adjacent sealing plugs on the piston unit 1. For example, when a water inlet channel connected by a waterway formed by two adjacent sealing plugs, water can flow out from the water outlet channel on the other side. By moving the piston unit 1 again, the waterway entering the piston unit 1 can be changed, and the changed waterway can flow out from another opening structure 8. If other functions are to be realized, it is also achieved in the same way. Further, the present utility model realizes the need for switching different waterways by providing multiple moving piston units 1. The principle of the implementation process of other piston units 1 is similar.

[0031] As a further improvement, a connecting plate is connected with an adapter plate 9, and the driving structure drives the piston unit to move through the adapter plate 9. Further preferably, the adapter plate is provided with a cylindrical structure 10 with threads, and the driving structure is provided with a screw 11, and the movement of the adapter plate is driven by the screw. The forward and reverse rotation of the driving structure (driving motor) is used to realize the forward and backward movement of the piston unit 1.

[0032] As a further improvement, corresponding sealing plugs are arranged on the piston unit according to the waterway direction, and the number and compartments of the sealing plugs can be set according to needs.

[0033] The technical principle of the present utility model is described above in combination with specific embodiments, which is only the preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions within the idea of the present utility model belong to the protection scope of the present utility model. Those skilled in the art can think of other specific embodiments of the present utility model without creative labor, and these embodiments will fall within the protection scope of the present utility model.
