[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See Figures 1 to 3The present invention provides an electric toilet with improved deodorizing ability, comprising a toilet 100, a water tank 200 fixed to the rear of the toilet bowl, a main unit 10 installed above the water tank 200, the main unit 10 comprising a base 300 and a cover 900, a fan 400 accommodated inside the main unit and fixed to the base 300, a first air duct 41 communicating with and fixedly connected to the inlet of the fan 400, a second air duct 42 communicating with and fixedly connected to the outlet of the fan 400, and a seat ring 950 hinged to the main unit 10, wherein the upper end of the water tank 200 of the present invention is The base 300 is open and its lower end is closed to form a receiving chamber 21 for receiving flushing water. The base 300 extends downward on the side of the opening relative to the water tank 200 to form a hollow cylindrical filter portion 310 extending into the receiving chamber 21. The inner cavity 31 of the filter portion 310 is provided with a baffle 311 which divides the upper section of the opening end of the inner cavity 31 into two areas (the lower section of the inner cavity 31 located under the baffle 311 is connected), and a through hole 320 connected to the receiving chamber 21 is provided in the lower section of the inner cavity 31, so that flushing water can enter the inner cavity 31. The liquid level of the flushing water is generally set higher than the bottom end of the baffle 311.

[0023] The electric toilet of the present invention also includes a first air duct cover 500 and a second air duct cover 600. Specifically, see Figure 6 and Figure 7 The first air duct cover 500 is in the shape of a semi-closed pipe, with a first opening 510 opened along the air circulation direction at one end and an exhaust hole 520 connected to the inlet of the fan at the other end; the second air duct cover 600 is also in the shape of a semi-closed pipe, with an air inlet hole 610 connected to the outlet of the fan 400 at one end and a second open opening 620 at the other end. The inner wall of the middle part of the second air duct cover 600 is provided with ribs to form a partition part 630 for dividing the flow direction of the air duct. During assembly, the first air duct cover 500 is placed on the base 300, enclosing the first air duct 41. The second air duct cover 600 is placed on the base 300, forming the second air duct 42. After the second air duct cover 600 is placed on the base 300, its barrier portion 630 faces the baffle 311. This allows air entering the second air duct to be blocked by the barrier portion 630 and the baffle 311, preventing it from flowing through the inner cavity 31 of the filter portion 310. This design directly utilizes the base as part of the components that enclose the first and second air ducts, reducing the number of parts while fully utilizing the base's axial space. The result is a simple and reliable structure, which helps reduce the axial height of the electric toilet.

[0024] In this embodiment, the filter unit 310 is connected midstream to the second air duct 42. Specifically, the connection of the filter unit 310 to the midstream of the second air duct 42 refers to the connection between the partition 630 and the baffle 311, which separates the second air duct 42 into a second air duct inlet section 44 and a second air duct outlet section 45. During operation, air enters the filter unit's inner cavity 31 through the second air duct inlet section 44. The air is then blocked by the baffle and flows to the bottom section of the inner cavity 31, where it bends upward and flows out of the filter unit 310 into the second air duct outlet section 45. The electric toilet design of this utility model extends the filter unit into the water tank's accommodating cavity and is located midstream in the second air duct. This fully utilizes the axial space of the electric toilet and absorbs and filters the air drawn into the air duct with flushing water. The overall structure is simple and reliable, improving the deodorization performance of the electric toilet while maintaining the axial height of the entire unit, without requiring additional consumables. Of course, in other embodiments, the filter unit 310 can also be located midstream in the first air duct 41.

[0025] In order to simplify the mold structure of the base 300, the baffle 311 and the through hole 320 can be formed in one injection molding of the base 300. Figure 3 and Figure 5 The baffle 311 of the present invention is a rib protruding from the inner wall of the filter portion 310 to separate the axial opening of the inner cavity. In the axial projection, the outline of the projection of the baffle 311 is within the outline of the projection of the through hole 320.

[0026] See Figures 3 to 5 The electric toilet with enhanced deodorizing capabilities of the present invention also includes a blower device 700 mounted on the base 300. The blower device 700 is provided with an air duct housing 710 having an air outlet 71. Furthermore, the base 300 has a columnar rim portion 330 protruding from the end surface facing the air duct housing 710, which has an inlet 33 and an outlet 32. During installation, the air duct housing 710 of the blower device 700 is placed over the rim portion 330 and, together with the rim portion 330, forms a front air duct 43. After assembly, the first air inlet 1 of the first air duct 41 is connected to the outlet 32. In this way, the blower device housing and the rim portion on the base form a front air duct that extends beyond the first air duct, preventing the arrangement of other parts from being affected by the first air duct, thereby simplifying the arrangement of the base parts.

[0027] Further, see Figure 2 and Figure 3 The water tank 200 is provided with an overflow port 210 leading to the toilet bowl 110. In axial projection, the outlines of the inlet 33 and the blowing port 71 of the blowing device at least partially overlap with the outline of the overflow port 210. This design, by axially stacking the inlet, blowing port, and overflow port on the base, helps reduce the lateral space occupied by the inlet, blowing port, and overflow port, facilitating the layout of other components of the electric toilet.

[0028] Further, see Figure 2 and Figure 3 The electric toilet with enhanced deodorization capabilities of this utility model also includes a filter 800 mounted on the baffle. The distances from the top and bottom axial ends of the filter 800 to the horizontal plane S are H1 and H3, respectively. The distance from the bottom axial end of the overflow outlet 71 to the horizontal plane S is H2. When the water tank is filled with liquid, the distance from the liquid level to the horizontal plane S is H4. Therefore, H1 is greater than H2, and H3 is less than H4. This design allows the filter, which has absorbed water, to filter the air in the air duct, thereby improving deodorization efficiency.

[0029] See Figure 2 In order to further filter the gas in the air duct and improve the deodorization ability, activated carbon 650 is provided in the second air duct 42 of the utility model.

[0030] The working principle of the electric toilet with enhanced deodorizing ability of the utility model is shown in Figure 3 As described above, when the deodorizing function of the electric toilet is turned on, the fan 400 is started, and the gas in the toilet bowl 110 enters from the overflow port 210 through the inlet port 33 and enters the front air duct 43 under the suction force generated by the fan 400. The gas flowing through the front air duct 43 passes through the exhaust port 32 and enters the first air duct 41. The gas entering the first air duct 41 passes through the pressure chamber of the fan 400 and enters the second air duct air inlet section 44. After the wind flows into the inner cavity 31 of the filter part 310 in the second air duct air inlet section 44, it enters the second air duct exhaust section 45 and is discharged to the outlet. The water arranged in the filter part 310 is used to absorb and filter the gas sucked in from the toilet bowl 110, thereby improving the deodorizing ability of the electric toilet.
