As shown in fig. 1 to 7, the present invention provides an air supply device 100.

Referring to fig. 1 to 7 in combination, the utility model provides an air supply arrangement 100 is applied to intelligent squatting pan 1000, and air supply arrangement 100 includes casing 10, fan 30, stoving subassembly 50 and bacteriostatic component 70. An air duct 11 for air to flow is formed in the shell 10, and the air duct 11 is provided with an air inlet 12 and an air outlet 15; the fan 30 is arranged in the air duct 11; the drying component 50 is arranged in the air duct 11; the bacteriostatic component 70 is arranged in the air duct 11, the bacteriostatic component 70 comprises a discharge electrode 71 and a collector electrode 73 which are oppositely arranged, and a high-voltage electric field is formed between the discharge electrode 71 and the collector electrode 73.

It should be noted that the intelligent toilet 1000 needs to have the requirement for cleaning the private parts of the user and drying the private parts after cleaning, so as to improve the use experience of the user. Specifically, in the operation process of the air supply device 100 provided in this embodiment, the fan 30 sucks air from the air inlet 12 and forms an airflow flowing along the air duct 11 toward the air outlet 15, the drying component 50 in the air supply device 100 provides heat to the formed airflow to heat the airflow, and the heated airflow flows out along the air duct 11 and moves toward the private part of the user, so that the drying function of the intelligent toilet 1000 is realized.

It should be noted that the airflow formed by the blower 30 and heading to the air outlet 15 passes through the high voltage electric field formed between the discharge electrode 71 and the collector electrode 73 of the bacteriostatic component 70, when the airflow passes through the high voltage electric field, moisture carried in the airflow is ionized to form nano water ions with hydroxyl radicals, and the nano water ions are not easily combined with oxygen and nitrogen in the air, so that the airflow can exist in the air for a long time. The nanometer water ions existing in the air for a long time can be adhered to the surfaces of various bacteria, a large amount of hydroxide radicals contained in the nanometer water ions are in full contact with the bacteria, the hydroxide ions in the bacteria are extracted out and combined into water, and therefore the effect of reducing the activity of the bacteria is achieved.

It can be understood that, in the working process of the bacteriostatic component 70, the air that needs to flow is to wrap and carry the nano water molecules and to be uniformly distributed to the surface that needs to be bacteriostatic, and when the drying component 50 and the bacteriostatic component 70 are disposed in the same air duct 11 formed in the casing 10, the air flow provided by the fan 30 may be used for the drying component 50 to provide heated air, and may also be used for the bacteriostatic component 70 to provide air containing nano water ions, and on the premise that the function of the air supply device 100 is not affected, the space utilization rate of the air supply device 100 is further increased, so that the internal structure of the air supply device 100 is compact.

In an embodiment of the present invention, as shown in fig. 3 to 7, the bacteriostatic component 70 includes a fixing base 75, a collecting electrode 73 and a discharging electrode 71. The fixed seat 75 is detachably mounted in the air duct 11, and a through hole for air flow circulation is formed in the fixed seat 75; the collector electrode 73 is arranged in the through hole, and the collector electrode 73 has two opposite ends and is respectively connected to two symmetrical side wall surfaces in the through hole; discharge electrode 71 is provided to protrude from the inner wall surface of the through hole, and discharge electrode 71 is positioned on the side of collector electrode 73 and extends toward collector electrode 73.

It can be understood that the through hole formed by the enclosing of the fixing base 75 and allowing the air flow to flow leads the air flow generated by the fan 30 in the air supply device 100, when the air flow flows through the fixing base 75, at least a part of the air flow is collected towards the through hole, so that the efficiency of the air flow passing through the high-voltage electric field is increased, that is, the efficiency of the bacteriostatic component 70 for generating the nano water ions is increased, and the working efficiency of the bacteriostatic component 70 is further increased.

Specifically, the collector electrodes 73 connected to the two symmetrical side wall surfaces in the through hole have a larger contact area with air than that of the collector electrodes connected to only one section of the collector electrodes arranged in the through hole, so that in the working process of the bacteriostatic component 70, as many nano water ions as possible are generated in unit time, and the working efficiency of the bacteriostatic component 70, that is, the working efficiency of the air supply device 100, is further increased.

In an embodiment of the present invention, referring to fig. 3 to 7, the middle portion of the collecting electrode 73 is provided with a water collecting structure 77, the water collecting structure 77 is just set to the discharge electrode 71, and the outer side of the water collecting structure 77 is a circular arc surface.

It can be understood that the arc surface of the water collecting structure 77 protruding from the middle of the collecting electrode 73 has a larger contact area with air, and the water collecting structure 77 disposed opposite to the discharge electrode 71 further increases the efficiency of ionizing moisture in air during the operation of the air supply device 100, that is, increases the operating efficiency of the bacteriostatic component 70 and the air supply device 100. Meanwhile, the convexly arranged arc surface has a smaller size structure, so that the installation space required by the bacteriostatic component 70 is further reduced, and the space utilization rate of the bacteriostatic component 70 and the air supply device 100 is increased.

Specifically, before the bacteriostatic component 70 starts to operate or stops operating, the water collecting structure 77 protruding from the arc surface in the middle of the collecting electrode 73 guides liquid drops formed by gathering moisture in the gas possibly existing on the collecting electrode 73 to the joint of the water collecting structure 77 and the collecting electrode 73 from the top end protruding from the arc surface, and when the liquid moves from the top end protruding from the water collecting structure 77 to the joint of the water collecting structure 77 and the collecting electrode 73, the liquid drops are continuously influenced by the high-voltage electric field to be continuously converted into nano water ions.

In an embodiment of the present invention, with reference to fig. 4 to fig. 7, the discharge electrode 71 includes the transition section 711 and the ionization section 713 that communicate, the one end fixed connection of transition section 711 in through-hole internal wall face, ionization section 713 connect in the other end that the transition section 711 deviates from the fixing base 75, the cross-sectional area of ionization section 713 is reduced gradually by the junction of ionization section 713 and transition section 711 towards the one end that deviates from the transition section 711.
