As shown in Figure 10, in one embodiment, one end of protective cover 900 has inclined-plane 920.Inclined-plane 920 and handle 100 Extending direction formed angle.So set, protective cover 900 can be flowed through in first fluid channel 101 for fluid Certain guiding role is provided, in the process so as to reduce hanging down due to flow direction when fluid flows through protective cover 900 It is straight to change the turbulent flow in first fluid channel 101, and then achieve the purpose that reduce noise.

As shown in FIG. 9 and 10, in the present embodiment, locating slot 150 is set on the inner sidewall of the first inner casing 132.First Support division 170 is additionally provided on the inner sidewall of inner casing 132.Controller 800 has the capacitance part extended towards the second inner casing 134 protrusion 860.Specifically, capacitance part 860 is set to the second side of the control unit 840 far from first control units 820.900 clamping of protective cover limit Between support division 170 and capacitance part 860.

As shown in figure 12, further, the inner sidewall of the second inner casing 134 is equipped with pressure contact portion 180.Pressure contact portion 180 can Protective cover 900 is pressed so that protective cover 900 to be fixed on controller 800.Specifically, pressure contact portion 180 may include multiple.Multiple pressures Socket part 180 is arranged in array on the inner sidewall for being distributed in the second inner casing 134, to improve the pressure of 900 relative controller 800 of protective cover Connect stability.

Each technical characteristic of above embodiments can be combined arbitrarily, for simplicity of description, not to above-described embodiment In each technical characteristic it is all possible combination be all described, as long as however, the combination of these technical characteristics be not present lance Shield all should be considered as described in this specification.

Above embodiments only express the several embodiments of the utility model, and the description thereof is more specific and detailed, but simultaneously The limitation to utility model patent range therefore cannot be interpreted as.It should be pointed out that for the ordinary skill people of this field For member, without departing from the concept of the premise utility, various modifications and improvements can be made, these belong to this reality With novel protection scope.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
