[0030] refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 The present application provides a toilet cover 100, which has a seating surface 111 for toilet sitting, has a hollow structure and forms a ventilation cavity 113 in the toilet cover 100, and a vent hole 112 is provided on the side of the toilet cover 100 away from the seating surface 111, and the vent hole 112 is in fluid communication with the ventilation cavity 113. The toilet cover 100 is provided with an air guide tube 200, one end of the air guide tube 200 is in fluid communication with the ventilation cavity 113, and the other end of the air guide tube 200 is located outside the toilet cover 100 to guide the gas entering the ventilation cavity 113 through the vent hole 112 to flow out.

[0031] The toilet seat 100 provided in the present application has a hollow structure and forms a ventilation cavity 113. One end of the air guide tube 200 is connected to the ventilation cavity 113 to guide the gas entering the ventilation cavity 113 through the ventilation hole 112 to be discharged outside the toilet 300. Since the ventilation hole 112 is arranged on the side of the toilet seat 100 away from the seating surface 111, the intensity of the airflow directly flowing to the human skin can be reduced when the gas is discharged, reducing discomfort, and also avoiding residual odor on the skin surface.

[0032] Specifically, in the present embodiment, the toilet cover 100 includes a gasket upper plate 110 and a gasket lower plate 120 .

[0033] The gasket upper plate 110 is in the shape of an annular plate. Figure 2 As shown in FIG. 1 , the upward side of the gasket upper plate 110 is a seating surface 111. Figure 3 As shown, the inner and outer edges of the gasket upper plate 110 are both provided with ridges 114 protruding away from the seating surface 111 , so that a groove is formed on the side of the gasket upper plate 110 away from the seating surface 111 .

[0034] refer to Figure 3 The gasket lower plate 120 is also annular. In normal use, the gasket lower plate 120 and the gasket upper plate 110 are in a stacked state, and the inner and outer edges of the gasket lower plate 120 are roughly overlapped with the inner and outer edges of the gasket upper plate 110. The side of the gasket lower plate 120 facing the seating surface 111 corresponds to the groove, so that the gasket lower plate 120 and the gasket upper plate 110 enclose a ventilation cavity 113.

[0035] In this embodiment, the washer lower plate 120 is fastened to the washer upper plate 110 by screws (not shown), so that when the ventilation cavity 113 needs to be cleaned, the screws can be loosened to separate the washer upper plate 110 from the washer lower plate 120. In some other embodiments, the washer lower plate 120 and the washer upper plate 110 can also be fastened by bonding, welding, etc. In addition, the washer lower plate 120 and the washer upper plate 110 can also be integrally formed.

[0036] One end of the air duct 200 is connected to the gasket upper plate 110 and communicates with the ventilation cavity 113. The other end of the air duct 200 is fixedly arranged on the wall and leads to the outside, or is fixedly connected to the exhaust device to discharge the gas with odor.

[0037] refer to Figure 3 4 , in one embodiment, the outer wall of the air duct 200 is provided with a groove portion 210, and the groove portion 210 is arranged along the circumference of the air duct 200. One end of the air duct 220 is provided with a joint 220, and the joint 220 is rotatably sleeved on the air duct 200, and the joint 220 is connected to the gasket upper plate 110. Figure 3Taking the toilet cover 100 shown in the figure and the air duct 200 shown in Figure 4 as examples, an internal threaded portion 221 is provided at one end of the joint 220, and the gasket upper plate 110 is provided with a connecting pipe 116. One end of the connecting pipe 116 is located in the ventilation cavity 113, and the other end is located outside the ventilation cavity 113, and an external threaded portion (not shown) is provided on the outer peripheral side of a part thereof located outside the ventilation cavity 113. By screwing the internal threaded portion 221 and the external threaded portion together, the joint 220 and the connecting pipe 116 can be screwed together.

[0038] The joint 220 in this embodiment is cylindrical, and the joint 220 is provided with a joint portion 222 extending radially inwardly of the joint 220, and the joint portion 222 is nested in the groove portion 210. Therefore, the joint portion 222 can constrain the movement of the joint 220 in the length direction of the air duct 200, and prevent the joint portion 222 and the air duct 200 from being separated from each other. It can be understood that the groove portion 210 is annular, and the joint portion 222 can move circumferentially along the groove portion 210, so that the joint 220 and the air duct 200 can still rotate relative to each other. Then, in the process of lowering or lifting the toilet cover 100, the joint 220 fixedly connected to the gasket upper plate 110 can be adaptively rotated relative to the air duct 200, reducing the severity of the torsion and deformation of the air duct 200 to match the position of the connecting pipe 116, and effectively extending the service life of the air duct 200.

[0039] In one embodiment, the toilet cover is further provided with a buffer member 117. Figure 3 As shown, a fixing member 115 is disposed in the groove, and a slot is formed on the fixing member 115 for inserting a buffer member 117. When the buffer member 117 is placed in the slot, the side of the buffer member 117 away from the seating surface 111 protrudes from the gasket lower plate 120. When the toilet cover 100 is lowered, the buffer member 117 can contact the toilet seat instead of the gasket lower plate 120, so as to prevent the gasket lower plate 120 from breaking due to excessive collision strength between the gasket lower plate 120 and the toilet seat.

[0040] In one embodiment, the inner edge of the gasket lower plate 120 is provided with a recess 121, and the convex ridge 114 and the inner side of the gasket lower plate 120 corresponding to the recess 121 are enclosed to form a vent 112. The inner edge of the gasket lower plate 120 is provided with a plurality of recesses 121. In an exemplary embodiment, as shown in FIG. Figure 3 and Figure 5 As shown, the inner edge of the gasket lower plate 120 is symmetrically provided with two recesses 121 on the left and right sides. In other embodiments, the recesses 121 may also be provided with other numbers, and the number and arrangement form on the left and right sides may also be asymmetrical.

[0041] When the washer lower plate 120 and the washer upper plate 110 are in an overlapping state and are fastened together, as shown in FIG. Figure 5As shown, at this angle, the convex ridge 114 located at the inner edge of the gasket upper plate 110 does not completely cover the concave position 121 to form the vent hole 112. When the toilet cover 100 is put down for use, the gas in the toilet 300 can enter the ventilation cavity 113 through the vent hole 112 and then be discharged through the air duct 200. The concave position 121 is set on the inner edge of the gasket lower plate 120 to form the vent hole 112 in combination with the convex ridge 114 of the gasket upper plate 110. During the production process, the processing difficulty of the gasket upper plate 110 and the gasket lower plate 120 is low, and the assembly difficulty is relatively low. Moreover, the vent hole 112 is located at the inner edge of the toilet cover 100 and will not be blocked by the toilet seat, so the ventilation capacity is good.

[0042] Furthermore, the vent hole 112 is in an elongated shape, and the width of the vent hole 112 is between 3 mm and 6 mm. Limiting the width of the vent hole 112 within this threshold can reduce the incidence of liquid in the toilet splashing into the ventilation cavity 113 through the vent hole 112, and the ventilation cavity 113 and the air guide tube 200 are not easy to breed bacteria.

[0043] In one embodiment, the toilet cover 100 further includes an air extraction device (not shown), which is connected to one end of the air duct 200 located outside the toilet cover 100. The air extraction device can be an exhaust fan or an air pump, etc., which can accelerate the discharge of gas in the air duct 200, thereby reducing the occurrence of odor from the toilet 300.

[0044] refer to Figure 6 Furthermore, the toilet cover 100 also includes a trigger assembly 130. The trigger assembly 130 includes a first electric contact 131 and a spring 132, and the first electric contact 131 is provided with a first electric contact (not shown). The buffer 117 is provided with a second electric contact 133, and the second electric contact 133 is provided with a second electric contact (not shown). The first electric contact 131, the second electric contact 133, the air extraction device (not shown) and the power supply (not shown) form a circuit loop. The power supply can be a DC 6V or 12V power supply, or an AC power supply.

[0045] Furthermore, a magnetic switch (not shown) may be provided in the circuit loop to facilitate connecting or disconnecting the circuit so as to control the working state of the air extraction device.

[0046] In this embodiment, the spring 132 is installed between the buffer 117 and the washer upper plate 110. When the spring 132 is compressed, the distance between the buffer 117 and the washer upper plate 110 is shortened. Figure 2 and Figure 6It can be understood that when the toilet lid 100 is put down and the user sits on the seating surface 111, the buffer 117 is supported upward by the toilet seat, so that the spring 132 is compressed until the first electrical contact and the second electrical contact abut against each other to form an electrical connection, and then the circuit formed by the first electrical contact 131, the second electrical contact 133 and the air extraction device is in a connected state, the air extraction device starts to work, and the odorous gas in the toilet is discharged from the air duct 200 through the ventilation cavity 113. When the user leaves the seating surface 111, the spring 132 is reset, so that the first electrical contact 131 and the second electrical contact 133 are separated from each other, the first electrical contact and the second electrical contact are out of contact, and the circuit is disconnected. By setting the trigger component 130, the vacuum device automatically works when the user sits on the seating surface 111, and does not work when the user does not sit on the seating surface 111 or the toilet lid 100 is not lowered, thereby shortening the unnecessary working time of the vacuum device, saving electricity and extending the service life of the vacuum device.

[0047] In another embodiment, the circuit has a delay switch (not shown), the delay connection time of the delay switch is more than 20 seconds, and the delay closing time is more than 10 seconds. In this embodiment, the delay switch is set to delay the closing of the circuit for 25 seconds and delay the disconnection of the circuit for 15 seconds. In this way, when the user puts down the toilet lid 100 to urinate, the odor is small, so the circuit is not closed in a time shorter than 25 seconds, and the exhaust device is not started, further shortening unnecessary working time. And when the user puts down the toilet lid 100 to defecate, the delay switch delays the disconnection of the circuit for 15 seconds, that is, the exhaust device continues to work for 15 seconds after the user leaves the seating surface 111, which can remove odor as much as possible and improve the deodorization effect.

[0048] The present application also provides a toilet 300, such as Figure 1 and Figure 2 As shown, the toilet 300 includes the above-mentioned toilet cover 100. This toilet 300 has the function of removing odors, but does not need to modify the toilet seat and the water tank or other structures, has a simple structure and low cost.

[0049] refer to Figure 7In some embodiments, the toilet 300 further includes a check valve 310, an exhaust device 320 and a cyclone ventilator 330. The exhaust device 320 and the check valve 310 are both arranged on the air duct 200. When the exhaust device 320 is powered on, the gas in the ventilation cavity 113 can be discharged outward through the air duct 200. The check valve 310 can prevent the air flow from flowing to the ventilation cavity 113 when the exhaust device 320 is not working, so as to avoid sucking back the air with odor. The cyclone ventilator 330 is an exhaust device 320 that does not require power. The arc-shaped fan blades can be rotated by natural wind or the temperature difference between indoor and outdoor, so as to improve the indoor and outdoor air circulation effect. In this embodiment, the cyclone ventilator 330 is connected to one end of the air duct 200 away from the toilet cover 100, and is fixedly installed on the roof or the outer wall, so that the air with odor in the air duct 200 can be taken out of the room.

[0050] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
