[0002] The patent with publication number CN111346443A discloses a filtering and sterilizing structure for a deodorizing device for a toilet or squat toilet, which includes a casing, a first fan, a second fan and a filter element; the inner cavity of the casing includes an air inlet exchange chamber, a front filter chamber, a first installation chamber, a rear filter chamber and an air outlet exchange chamber which are connected in sequence; the air inlet exchange chamber is provided with an air inlet and the air outlet exchange chamber is provided with an air outlet, the first fan is installed in the air inlet exchange chamber so that the gas is sucked from the air inlet into the air inlet exchange chamber and discharged to the front filter chamber; the second fan is installed in the air outlet exchange chamber, and is used to suck the gas in the rear filter chamber into the air outlet exchange chamber and discharge it from the air outlet; the filter element is installed in the first installation chamber, and is used to deodorize and sterilize the gas flowing through the front filter chamber and the rear filter chamber.

[0003] Although the above-mentioned filtering and sterilizing structure for toilet and squat toilet deodorizing device can filter the odor generated when using the toilet and perform double bacterial disinfection on the air and water in the water tank, it still has the following shortcomings: the setting of the double-cavity circulation pipe requires more installation space, which will further make the space of the bathroom tight if the original space of the bathroom is not rich enough. In addition, there are many parts and the overall structure is relatively complex, resulting in high production and manufacturing costs. In the current fierce market competition environment, it cannot reflect the price advantage and lacks competitiveness. Summary of the invention

[0006] The first interface of the three-way connecting pipe is connected to the air inlet, the second interface of the three-way connecting pipe is connected to the overflow pipe of the water tank, and the third interface of the three-way connecting pipe is located below the liquid level in the water tank;

[0007] The ozone generator includes an ozone generating sheet; the ozone generating sheet is located inside the three-way connecting pipe, and is used to mix the generated ozone with the odor entering from the overflow pipe to sterilize and deodorize, and discharge the residual ozone into the water tank after passing through the inner cavity of the shell to sterilize the water.

[0008] The beneficial effects of the present invention are embodied in:

[0009] Deodorization and sterilization principle: start the fan and ozone generator when using the toilet. Under the suction of the fan, the generated odor passes through the overflow pipe, the three-way connecting pipe and the shell in turn, and finally discharged into the water tank from the air outlet. The ozone generated by the three-way connecting pipe is mixed with the odor to deodorize and sterilize the odor. Finally, the remaining ozone is discharged into the water tank, and then the water in the water tank is sterilized, thereby achieving a double sterilization effect. The overall structure of this equipment is compact, the space occupied in the bathroom is very small, and the installation is very convenient. In addition, this equipment has few parts and components, low production and manufacturing costs, and has strong market competitiveness.

[0010] Preferably, the second interface and the third interface are both vertically downward.

[0011] Preferably, the three-way connecting pipe is provided with an extension pipe for extending the third interface to below the liquid level in the water tank.

[0012] Preferably, the first interface and the air inlet are connected in a horizontal direction, and the air outlet is vertically downward.

[0013] Preferably, the air outlet extends to below the liquid level of the water tank through an extension tube.

[0014] The design of the three interfaces of the three-way connecting pipe simplifies the connection structure of the pipeline to the greatest extent, reducing the total length of the pipeline. The first interface is directly connected to the air inlet of the shell, and the air outlet of the shell directly leads downward into the water tank, further shortening the length of the total pipeline. After the total pipeline is shortened, the effect of sucking odor is greatly improved, and the efficiency of odor treatment is also improved.

[0015] Preferably, the ozone generator comprises a power module electrically connected to the ozone generating sheet; the power module is located in the inner cavity of the shell.

[0016] Preferably, it also includes an induction switch; the induction switch is connected in series with the power module and the fan respectively.

[0017] How to use: When using the toilet, the sensor switch automatically turns on, and the external power supply supplies power to the power module and the fan, continuously deodorizing and sterilizing. After using the toilet, the sensor switch automatically turns off, cuts off the external power supply, and the power module and the fan stop working. The entire operation method is easy and extremely convenient to use.

[0018] Preferably, the ozone generating sheet is fixed in the first interface via a connecting piece.

[0019] Preferably, the length of the connecting piece is the same as the inner diameter of the first interface, and arc surfaces matching the inner diameter of the first interface are respectively provided at both ends of the connecting piece. The two arc surfaces are pressed against the inner wall of the first interface along the radial direction of the first interface through the connecting piece, thereby making the connecting piece stuck in the first interface.

[0020] Preferably, an opening for inserting the ozone generating sheet is provided in the middle of the connecting piece.

[0021] The shape of the connector is long and narrow, and its two ends are enlarged and the enlarged part is provided with arc surface, and the arc surface is completely fitted with the inner wall of the first interface. The connector is inserted into the first interface and the inner wall of the first interface is interfered with by the two arc surfaces, so that the connector and the first interface form a detachable connection. When the ozone generator fails or reaches the end of its service life, the ozone generating sheet can be quickly removed through the connector, and replacement is very convenient.

DETAILED DESCRIPTION

[0032] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0033] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the invention belongs.

[0034] like Figure 5 and Figure 8 As shown, this embodiment provides a toilet sterilization and deodorization main box, including a housing 1, a fan 2, an ozone generator, and a three-way connecting pipe 4. The three-way connecting pipe 4 is provided with three interfaces, namely a first interface 5, a second interface 6, and a third interface 7. The second interface 6 and the third interface 7 are vertically downward, and the three-way connecting pipe 4 is provided with an extension pipe 8 for extending the third interface 7 to below the liquid level in the water tank 17, so that the second interface 6 and the third interface 7 form a long and short structure. The first interface 5 is perpendicular to the second interface 6 and the third interface 7, that is, they are in the horizontal direction.

[0035] like Figures 1 to 3 , Figure 8 As shown, the fan 2 is installed in the inner cavity of the housing 1, and the side wall of the housing 1 is provided with an air inlet 9 opposite to the air inlet end of the fan 2, and the side wall of the housing 1 is provided with an air outlet 10 opposite to the air outlet end of the fan 2. The housing 1 in this embodiment is installed on the water tank 17 of the toilet or the water tank 17 of the flushing bowl, and the air outlet 10 is connected to below the liquid level in the water tank 17. Specifically, the air outlet 10 extends to below the liquid level in the water tank 17 through an extension pipe 11. The first interface 5 of the three-way connecting pipe 4 is connected to the air inlet 9, the second interface 6 of the three-way connecting pipe 4 is connected to the overflow pipe of the water tank 17, and the third interface 7 of the three-way connecting pipe 4 is located below the liquid level in the water tank 17.

[0036] The structure of the housing 1 and the three-way connecting pipe 4 and the connection relationship between the two simplify the connection structure of the pipeline to the greatest extent, reduce the total length of the pipeline, and the first interface 5 is directly connected to the air inlet 9 of the housing 1, and the air outlet 10 of the housing 1 directly leads downward into the water tank 17, further shortening the length of the total pipeline. After the total pipeline is shortened, the effect of sucking odor is greatly improved, and the efficiency of odor treatment is also improved.

[0037] like Figure 4 , Figure 6 and Figure 7 As shown, the ozone generator in this embodiment includes an ozone generating sheet 13, and a power module 12 electrically connected to the ozone generating sheet 13. The power module 12 serves as a power adapter for the ozone generating sheet 13, which is provided with overcurrent and overheat protection, automatic width adjustment, and frequency modulation. In the event of a short circuit or a circuit breaker, the power will be automatically cut off, thereby improving the safety level. The ozone generating sheet 13 is located inside the three-way connecting pipe 4, and is used to mix the generated ozone with the odor entering from the overflow pipe. Specifically, the ozone generating sheet 13 is fixed in the first interface 5 by a connector 14. The length of the connector 14 is the same as the inner diameter of the first interface 5, and arc surfaces 15 adapted to the inner diameter of the first interface 5 are respectively provided at both ends of the connector 14, and the two arc surfaces 15 are made to be close to the inner wall of the first interface 5 along the radial direction of the first interface 5 by the connector 14, so that the connector 14 is stuck in the first interface 5. An opening 16 for inserting the ozone generating sheet 13 is provided in the middle of the connector 14. The connector 14 is in the shape of a long strip, with its two ends expanded and the expanded part provided with a circular arc surface 15, and the circular arc surface 15 is completely fitted with the inner wall of the first interface 5. The connector 14 is inserted into the first interface 5, and the two circular arc surfaces 15 are interference-fitted with the inner wall of the first interface 5, so that the connector 14 and the first interface 5 form a detachable connection. When the ozone generator fails or ends its service life, the ozone generating sheet 13 can be quickly removed through the connector 14, and replacement is very convenient.

[0038] The power module 12 is located in the inner cavity of the shell 1, and is arranged side by side with the fan 2 in the inner cavity of the shell 1. For the circuit part in this embodiment, it also includes an induction switch. The induction switch is not drawn in the figure. The induction switch is connected in series with the power module 12 and the fan 2 respectively. How to use: The induction switch is automatically turned on when going to the toilet, and the external power supply supplies power to the power module 12 and the fan 2. Under the suction of the fan 2, the generated odor passes through the overflow pipe, the three-way connecting pipe 4 and the shell 1 in turn, and is finally discharged into the water tank 17 from the air outlet 10. The ozone generated by the three-way connecting pipe 4 is mixed with the odor to deodorize and sterilize the odor. Finally, the remaining odor is discharged into the water tank 17, and then the water in the water tank 17 is sterilized and disinfected, thereby achieving a double sterilization effect.

[0039] After using the toilet, the induction switch is automatically turned off, the external power supply is cut off, and the power module 12 and the fan 2 stop working. The whole operation method is easy and convenient to use.
