Alternatively, motor upper cover 24 it is provided with in housing 1, air intake 241 may be formed in motor upper cover 24, motor upper cover 24 is connected with motor accommodation portion 25, motor can be limited between motor upper cover 24 and motor accommodation portion 25 and hold chamber, wherein electric machine assembly 2 is contained in motor accommodation chamber, arranges shockproof part 6 between upper end and the motor upper cover 24 of electric machine assembly 2. In the such as example shown in Figure 14, Fig. 1 and Figure 16, motor upper cover 24 is fixing with motor accommodation portion 25 to be connected, shockproof part 6 is located between the upper end of electric machine assembly 2 and motor upper cover 24 with by spaced apart between upper end and the motor upper cover 24 of electric machine assembly 2, thus reducing motor oscillating intensity, prevent the friction of electric machine assembly 2 and motor upper cover 24, to reduce noise further.

It is understandable that, shockproof part 6 can be multiple, between the upper end of electric machine assembly 2 and motor upper cover 24, between first step structure 61 and the second step structure 62 of housing 1 of electric machine assembly 2 and between lower end and the housing 1 of electric machine assembly 2, shockproof part 6 all can be set, thus the vibration of steam cleaner 100 can be reduced to a greater extent, reduce noise.

Alternatively, shockproof part 6 can be rubber washer.

Further, as shown in Figure 13 and Figure 14, shockproof part 6 can being formed with multiple protruding 63, multiple protruding 63 intervals are arranged. In example as shown in figure 14, multiple protruding 63 can be located on the side that shockproof part 6 contacts with electric machine assembly 2, it is also possible to be located on the side that shockproof part 6 contacts with housing 1. Multiple protruding 63 have certain cushioning effect. Thus, by multiple protruding 63 shockproof properties that can improve shockproof part 6, thus reducing the vibration of electric machine assembly 2 further.

For multiple shapes of protruding 63, multiple protruding 63 are formed as zigzag, and each protruding 63 are formed as triangle. It should be noted that for multiple shapes of protruding 63, this utility model does not make particular determination, for instance, multiple protruding 63 may be alternatively formed to wavy.

Alternatively, shockproof part 6 can also be sponge or spring assembly.

In embodiments more of the present utility model, steam cleaner 100 can also include water pump (not shown go out), and water pump is connected between softening water tank 3 and steam generator 4. Further, water pump is connected between the water side of softening water tank 3 and steam generator water inlet 4131, and the soft water after can being softened by softening water tank 3 by water pump is delivered to steam generator 4.

In some embodiments that this reality is novel, softening resin filter element it is provided with in softening water tank 3, realize water correction effect by softening resin filter element, adopt softening water-resin filter element to be convenient for changing simultaneously, the bating effect of softening water tank 3 can be improved by regularly replacing softening resin filter element, and then the incrustation scale in steam generator 4 can be reduced further.

In embodiments more of the present utility model, as shown in Figure 21-Figure 24, housing 1 top can have opening 141, can be added water to softening water tank 3 by opening 141, steam cleaner 100 can also include removable cover 7, and removable cover 7 is movably connected to sentence at opening 141 and opens or closes opening 141. So, when softening water tank 3 needs to add water, user can open removable cover 7 and add water in softening water tank 3 in time, can be closed by removable cover 7 after complete addition of water, take out from without by softening water tank 3, it is simple to softening water tank 3 is added water.

Alternatively, as shown in Fig. 2, Fig. 3, Figure 20-Figure 23, the top of softening water tank 3 has water inlet 31, and water inlet 31 is corresponding with opening about 141. So, when softening water tank 3 is added water, user can be immediately seen the water inlet 31 of softening water tank 3, thus facilitating user to add water to softening water tank 3.

Further, water inlet 31 can be connected to water inlet pipe 311, and water inlet pipe 311 extends upwardly to adjacent openings 141 place so that adding water. As shown in Fig. 2, Fig. 3, Figure 20-Figure 23, water inlet pipe 311 is for straight tube and extends to adjacent openings 141 place straight up, open removable cover 7, can add water to softening water tank 3 either directly through water inlet pipe 311, thus, it is not only convenient for adding water, is also possible to prevent the water in softening water tank 3 by water inlet pipe 311 simultaneously and overflows.

Alternatively, removable cover 7 is as pivotally connected to the edge of opening 141. As shown in Figure 17-Figure 24, the side of removable cover 7 is connected with the inwall of opening 141, for instance, one of them of the edge of removable cover 7 and opening 141 can be formed pivotal axis, and another can be formed pivoting hole, pivotal axis coordinates pivotly in pivoting hole. Thus, removable cover 7 is turning to realize opening or closing opening 141 around the side of self.
