[0044] In order to make the technical problems, technical solutions and beneficial effects of the utility model to be solved more clear and explicit, the utility model will be further described in detail in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and do not limit the utility model.

[0045] Please refer to Figures 1-9 The utility model provides a kind of toilet deodorization device of preferred embodiment, comprising:

[0046] Toilet bowl body 10 has toilet bowl 11 and drain pipe 12;

[0047] Deodorization channel 20 has air inlet end and air outlet end, and the air inlet end of deodorization channel 20 is communicated with the inner cavity of toilet bowl 11;

[0048] Air extraction fan 30 is arranged in deodorization channel 20;

[0049] Shifter 40 includes upwardly arranged inlet 41, downwardly arranged outlet 42 and exhaust port 43 between inlet 41 and outlet 42, inlet 41 of shifter is communicated with the outlet of drain pipe 12, outlet 42 of shifter is communicated with ground drain port (not shown), exhaust port 43 of shifter 40 is communicated with air outlet end of deodorization channel 20, toilet bowl 11, drain pipe 12, shifter 40 and ground drain port are sequentially communicated.

[0050] When the air suction fan 30 is turned on, the odor in the toilet bowl 11 is sucked through the deodorizing channel 20 to the displacer 40 and discharged to the sewer.

[0051] In this embodiment, a base 50 is installed on the toilet bowl body 10, and a cover plate (not shown) is rotatably installed on the base 50. The deodorizing channel 20 is arranged on the base 50 and extends downward to the displacer 40.

[0052] In order to more effectively suck the odor, in this embodiment, the base 50 is further provided with a telescopic mechanism 60. The telescopic mechanism 60 includes a deodorizing telescopic pipe assembly 61 and a driving motor 62. The deodorizing telescopic pipe assembly 61 further includes a deodorizing fixed pipe 611 and a deodorizing telescopic pipe 612 capable of telescoping forward and backward relative to the deodorizing fixed pipe 611 under the driving of the driving motor 62. The inner cavities of the deodorizing fixed pipe 611 and the deodorizing telescopic pipe 612 form part of the deodorizing channel 20, and the front end of the deodorizing telescopic pipe 612 forms the air inlet end of the deodorizing channel 20. By arranging the deodorizing telescopic pipe 612 capable of telescoping, the deodorizing telescopic pipe 612 can be controlled to extend to a position closer to the middle of the toilet bowl 11 during deodorizing, so that the air suction can be more timely and sufficient, and the deodorizing effect is better.

[0053] In this embodiment, the telescopic mechanism 60 further includes a drying telescopic pipe assembly 63, which includes a drying fixed pipe 631 and a drying telescopic pipe 632 capable of telescoping forward and backward relative to the drying fixed pipe 631 under the driving of the driving motor 62. The inlet end of the drying fixed pipe 631 is connected with a drying channel arranged on the base 50 and used for drying the buttocks after washing. The deodorizing fixed pipe 611 is fixedly connected with the drying fixed pipe 631, and the deodorizing telescopic pipe 612 is fixedly connected with the drying telescopic pipe 632. Thus, only one driving motor 62 can be used to control the deodorizing telescopic pipe assembly 61 and the drying telescopic pipe assembly 63 at the same time, which is one thing with two uses, has a simpler structure, and saves the cost of one driving motor. In this embodiment, the deodorizing fixed pipe 611 and the drying fixed pipe 631 are the same pipe, and the deodorizing telescopic pipe 612 and the drying telescopic pipe 632 are integrally formed.

[0054] In this embodiment, a valve is arranged in the deodorizing channel 20, which blocks the deodorizing channel 20 when the air suction fan 30 is turned off. By arranging the valve to control the connection or disconnection of the deodorizing channel 20, the fluid (sewage or air suction) can be prevented from flowing backward into the toilet bowl 11 through the deodorizing channel 20 in the state without deodorizing.

[0055] Preferably, the valve is a one-way valve 70, which only allows the odor in the toilet bowl 11 to flow to the displacer 40 through the deodorizing channel 20, but does not allow the gas or sewage in the displacer 40 to flow backward to the toilet bowl 11 through the deodorizing channel 20.

[0056] In order to ensure that the air extraction fan 30 is not contacted by the sewage which may flow reversely, in the embodiment, the one-way valve 70 is preferably arranged downstream of the air extraction fan 30, and once the one-way valve 70 is closed, the sewage is blocked from flowing reversely to the upstream of the one-way valve 70.

[0057] Specifically, in the embodiment, the one-way valve 70 comprises a valve core 71 and a reset elastic member 72, and the deodorizing channel 20 is provided with a valve port 21, the valve core 71 opens the valve port 21 along the air extraction direction, and the reset elastic member 72 applies an elastic force to the valve core 71 in the direction of closing the valve port 21. The reset elastic member specifically adopts a compression spring.

[0058] In order to reliably open the one-way valve 70 during deodorization, in the embodiment, a control board (not shown) and an electromagnet driving device 80 are further included, the electromagnet driving device 80 and the air extraction fan 30 are both controlled by the control board, and the control board controls the air extraction fan 30 to be opened at the same time as controlling the electromagnet driving device 80 to drive the valve core 71 to open the valve port 21. Of course, the electromagnet driving device 80 for driving the one-way valve 70 can also be omitted, as long as in the design, the air force extracted by the air extraction fan 30 can directly drive the valve core 71 to open the valve port 21 by overcoming the elastic force of the reset elastic member 72.

[0059] Specifically, the electromagnet driving device 80 is provided with a telescopic top rod 81, after the control board controls the electromagnet driving device 80 to be powered on, the top rod 81 extends out and drives the valve core 71 to open the valve port 21; after the control board controls the electromagnet driving device 80 to be powered off, the top rod 81 retracts, and the valve core 71 is reset and closes the valve port 21 under the elastic force of the reset elastic member 72.

[0060] In the embodiment, the distance between the inlet 41 and the outlet 42 of the shifter 40 in the transverse direction is adjustable, and the adjustable structure can be known in the art, so that the universality of the shifter 40 is better.

[0063] Referring to Figures 7-9At this time, the control panel controls the exhaust fan 30 to open, the electromagnetic drive device 80 is powered on, the top rod 81 of the electromagnetic drive device 80 is extended and drives the valve core 71 to open the valve port 21, so that the deodorization channel 20 is in a communication state, and the exhaust fan 30 draws the odor in the bedpan 11 to the shifter 40 through the deodorization channel 20 and discharges it into the sewer. When the toilet flushes sewage, part of the odor drawn to the shifter 40 and the sewer can be dissolved in water, and the other part can be directly taken away by the water flow, completing the deodorization function.

[0064] The toilet deodorization device of the utility model ingeniously utilizes the existing shifter, adds an exhaust port on the existing shifter, and connects the exhaust end of the deodorization channel with the exhaust port of the shifter. In this way, when the exhaust fan is opened, the odor in the bedpan is drawn to the shifter through the deodorization channel and discharged into the sewer, and when the toilet flushes sewage, part of the odor drawn to the shifter and the sewer can be dissolved in water, and the other part can be directly taken away by the water flow, completing the deodorization function. The utility model not only has the advantages of simple structure, low cost, reliable function and high deodorization efficiency, but also does not need to open an exhaust port on the toilet body, that is, the toilet body does not need to be modified, and the existing toilet is modified into a toilet with the deodorization device of the utility model.
