Description

Technical Field

[0001] This utility model relates to the field of bathroom equipment technology, and in particular to an odorless smart toilet. Background Technology

[0002] As living standards improve, people's requirements for toilet environments and facilities are constantly increasing. Therefore, toilet designs are continuously being upgraded, and smart toilets are becoming increasingly popular. Smart toilets, initially designed for medical and elderly care, featured a warm water washing function. Later, with the introduction of advanced technology, they were manufactured with additional functions such as heated seats, warm water washing, and warm air drying.

[0003] To address toilet odors, smart toilets often include deodorizing functions. Existing toilets typically have a fan assembly with an air outlet facing the side of the toilet bowl within the mounting cavity. At the air outlet of this fan assembly is an adsorption layer filled with materials like activated carbon to absorb odors. However, because toilets are generally humid, odors are often stronger than in other living spaces. Therefore, the adsorption effect of this layer is significantly reduced, requiring frequent replacement. Furthermore, the drying process can blow odorous gases outside the toilet bowl, causing a large amount of odor to escape. Utility Model Content

[0004] The purpose of this invention is to provide an odorless smart toilet with good deodorization effect.

[0005] To achieve the above objectives, this utility model proposes an odorless intelligent toilet, including a base plate and a toilet body. The base plate is a functional integration plate of the intelligent toilet. The toilet body includes a sewage discharge chamber and an installation chamber located behind the sewage discharge chamber. An S-shaped curved sewage pipe is fixedly installed below the installation chamber. The front end of the sewage pipe is connected to the bottom end of the sewage discharge chamber, and the lower end of the sewage pipe is used to connect to the sewer. The base plate is fixedly installed in the installation chamber space above the sewage pipe. The base plate has a horizontally forward-extending receiving groove. The front end of the receiving groove is connected to the rear end of the sewage discharge chamber through a connecting port. A water spray pipe extending forward to the sewage discharge chamber is provided in the receiving groove. In addition, a suction and exhaust fan assembly is also provided in the receiving groove. The suction and exhaust fan assembly includes a first extension section extending horizontally on the receiving groove. The first extension section extends at least into the connecting port to draw air into the sewage discharge chamber. The suction and exhaust fan assembly also includes a second extension section extending downward and connected to the sewage discharge pipe. The second extension section serves as an exhaust pipe for the suction and exhaust fan assembly to exhaust air into the sewage discharge pipe.

[0006] Preferably, the front end of the drain pipe includes a water seal section for forming a water seal with the drain chamber, and the second extension of the suction and exhaust fan assembly is connected to the rear end of the water seal section.

[0007] Preferably, the water spray pipe and the first extension section are arranged side by side.

[0008] Preferably, the second extension section is connected to the rear section of the sewage pipe water seal section by a connector. The sewage pipe is provided with an interface section, and a flange protrudes from the side wall of the interface section towards the center of the interface section. The connector passes through the interface section, and one end of the connector is provided with a snap-fit ​​structure. The snap-fit ​​structure forms a snap-fit ​​with the inner end face of the flange. A sealing element is provided on the outer sleeve of the connector. The sealing element is adapted to the inner diameter contact surface and the outer end face of the flange. One side of the sealing element is provided with a pressure element that is lockably connected to the connector. The pressure element applies force to the sealing element by means of the lockable connection with the connector, so that the sealing element presses against the inner diameter contact surface and the outer end face of the flange. Thus, the sealing element and the snap-fit ​​structure cooperate to form a sealed connection between the connector and the interface section.

[0009] Preferably, the snap-fit ​​structure includes multiple spaced hooks that extend axially along the air hole. The hooks are cantilever structures, each including a deformable part and a snap-fit ​​part. One end of the deformable part is fixedly connected to the end of the connector, and the snap-fit ​​part is located at the other end of the deformable part. The snap-fit ​​part protrudes from the deformable part and is used to snap-fit ​​with the flange.

[0010] Preferably, the seal is annular and has a cross-sectional shape of "T". One end face of the seal is provided with a plug-in portion for insertion between the connector and the flange. The middle part of the seal is provided with a through hole for the connector to pass through. The plug-in portion is arranged around the through hole. On the axial section of the seal, the cross-section of the plug-in portion is wedge-shaped with the tip facing the inner end face of the flange, so that the plug-in portion forms an annular wedge structure.

[0011] Preferably, the outer wall of the connector is provided with a first thread structure, and the inner wall of the pressure member is provided with a second thread structure. The first thread structure and the second thread structure cooperate to form a threaded connection between the pressure member and the connector, thereby locking the connection as a threaded connection.

[0012] Preferably, the connector has air holes, and the snap-fit ​​structure includes multiple hooks extending axially along the air holes. The hooks are arranged circumferentially along the air holes of the connector, and adjacent hooks are spaced apart. The insertion part is an annular structure sleeved on the hooks.

[0013] Preferably, the toilet seat is made of ceramic or metal.

[0014] The beneficial effects of this utility model are as follows:

[0015] (1) This utility model uses a suction and exhaust fan assembly to draw and discharge the gas in the sewage chamber and guide it into the sewage pipe for exhaust, thus preventing the odor from overflowing into the toilet space. At the same time, connecting the suction and exhaust fan assembly to the sewage pipe after the water seal section also effectively prevents the odor from flowing back through the sewage pipe.

[0016] (2) The fan assembly is integrated into the receiving slot, making reasonable use of the space on the left and right sides of the receiving slot, so that the bottom plate structure is more compact. Attached Figure Description

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Where specific techniques or conditions are not specified in the embodiments, they shall be performed in accordance with the techniques or conditions described in the literature in the art or in accordance with the product manual.

[0025] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0026] See Figure 1-3As shown in the preferred embodiment of this utility model, an odorless intelligent toilet is proposed. The intelligent toilet is a toilet with an integrated functional panel added to an existing toilet to achieve multiple functions, such as washing, drying, sterilization, and deodorization. The intelligent toilet proposed in this utility model includes a toilet body 1 and a base plate 2. The toilet body 1 includes a drain chamber 12 and an installation cavity 11 located behind the drain chamber. An S-shaped curved drain pipe 14 is fixedly installed below the installation cavity. The front end of the drain pipe 14 is connected to the bottom end of the drain chamber 11, and the lower end of the drain pipe 14 is connected to a sewer. The base plate 2 is fixedly installed in the space of the installation cavity 11 above the drain pipe 14. The base plate 2 has a horizontally forward-extending receiving groove 22. The front end of the receiving groove 22 is connected to the rear end of the drain chamber through a connecting port 23. A water spray pipe 24 extending forward to the drain chamber 12 is provided in the receiving groove 22.

[0027] To further enhance the deodorization function of the smart toilet, this embodiment also includes a suction and exhaust fan assembly 21 within the receiving groove 22. The suction and exhaust fan assembly 21 is integrated within the receiving groove 22, with the water spray pipe 24 and the first extension section 211 arranged side-by-side. This utilizes the existing installation space of the smart toilet's integrated functional panel, resulting in a more compact structure. The suction and exhaust fan assembly 21 includes a first extension section 211 extending horizontally on the receiving groove 22. The first extension section 211 extends at least into the connecting opening to draw air into the sewage chamber. The fan assembly 21 also includes a second extension section 212 extending downwards and connecting to the sewage pipe. The second extension section 212 serves as the air outlet pipe for the suction and exhaust fan assembly 21 to discharge air into the sewage pipe 14. The front end of the drain pipe 14 includes a water seal section for forming a water seal with the drain chamber 12. The second extension section 212 of the suction and exhaust fan assembly 21 is connected to the rear end of the water seal section. This not only prevents the odor from the sewer from flowing back into the drain chamber 12 through the drain pipe 14, but also prevents the odor extracted from the drain chamber 12 from flowing back into the drain chamber 12 through the drain pipe 14. To prevent the odor from the sewer from flowing back through the suction and exhaust fan assembly 21, a check valve can be installed in the second extension section 212 as needed. When the suction and exhaust fan assembly 21 is working, the extracted gas opens the check valve and enters the drain pipe. When the suction and exhaust fan assembly 21 stops working, the check valve is closed.

[0028] See Figure 4-7As shown, the second extension section 212 is connected to the rear section of the water seal section of the sewage pipe 14 via a connector 3. The sewage pipe 14 is provided with an interface section 141. A flange 411 protrudes from the side wall of the interface section 141 toward the center of the interface section 141. The connector 3 passes through the interface section 141. One end of the connector 3 is provided with a snap-fit ​​structure 31, which is snapped into the inner end face of the flange 411. A sealing member 4 is provided on the outer sleeve of the connector 3. The sealing member 4 abuts against the outer end face of the flange. A pressure member 5 is provided on one side of the sealing member 4, which is lockably connected to the connector 3. The pressure member 5 applies force to the sealing member 4 by means of the lockable connection with the connector 3, so that the sealing member 4 presses against the flange 411. Thus, the sealing member 4 and the snap-fit ​​structure 31 cooperate to form a sealed connection between the connector 3 and the interface section 141.

[0029] The end of the interface section 141 located inside the drain pipe 14 is defined as the inner end, and the opposite end is defined as the outer end.

[0030] The snap-fit ​​structure 31 includes multiple spaced-apart hooks. Each hook is a cantilever structure, comprising a deformable portion 311 and a snap-fit ​​portion 312. One end of the deformable portion 311 is fixedly connected to the end of the connector 3, and the snap-fit ​​portion 312 is disposed at the other end of the deformable portion 311, protruding from the deformable portion 311. The snap-fit ​​portion 312 is used to snap-fit ​​with the flange 411. Since the hooks are cantilevered and adjacent hooks are spaced apart, when the connector 3 is inserted into the interface portion 141, the snap-fit ​​portion 312 can be pressed towards the center of the interface portion 141 by means of the elastic deformation of the deformable portion 311, thus facilitating the assembly between the connector 3 and the interface portion 141. When the snap-fit ​​portion 312 is inserted beyond the inner end face of the flange 411, the deformable portion 311 gradually recovers, causing the snap-fit ​​portion 312 to abut against the inner end face of the flange 411. The snap-fit ​​part 312 has a flat surface on one side facing the inner end face of the flange 411. The snap-fit ​​part 312 and the flange 411 are snapped together by the contact between the flat surface and the inner end face of the flange 411. That is, in the axial section of the connector 3, the snap-fit ​​part 312 has a structure similar to a triangle.

[0031] The seal 4 is an annular structure, with a insertion portion 41 on one end face for insertion between the connector 3 and the flange 411. The annular seal 4 has a through hole 42 in the middle for the connector 3 to pass through. The insertion portion 41 is arranged around the through hole 42. In the axial cross-section of the seal 4, the insertion portion 41 is wedge-shaped with its tip pointing towards the inner end face of the flange, thus forming an annular wedge structure. The annular insertion portion 41 can be inserted into the gap between the connector 4 and the flange 411, thereby strengthening the seal of the gap and preventing inadequate sealing due to insufficient size of the seal 4 caused by an excessively large gap.

[0032] The connector 3 has an air hole 32, and the hook extends axially along the air hole 32. The hook is arranged circumferentially along the air hole 32 of the connector 3. Therefore, there is a risk of leakage in the gap between the hooks, which may cause sewage or odor in the drain pipe 14 to leak out. In this utility model, the sealing element 4 is fitted onto the hook. More specifically, the insertion part 41 is an annular structure fitted onto the hook. The annular insertion part 41 can fill the gap between the hooks and seal the gap. The insertion part 41 extends toward the inner end face of the flange 411 to further improve the sealing effect.

[0033] The outer wall of the connector 3 is provided with a first thread structure 33, and the inner wall of the pressure member 5 is provided with a second thread structure 51. The first thread structure 53 and the second thread structure 51 cooperate to form a threaded connection between the pressure member 5 and the connector 3, thereby locking the connection as a threaded connection. In this example, the first thread structure 33 is the external thread on the outer wall of the connector 3, and the second thread structure 51 is the internal thread on the inner wall of the pressure member 5. The connection between the snap-fit ​​structure at the end of the connector 3 and the flange 411 is unidirectional. That is, the snap-fit ​​structure 31 can only prevent the connector 3 from leaving the interface portion 141 in the direction of the outer end face of the flange 411, but cannot prevent the connector 3 from moving in the direction of the inner end face of the flange 411. The pressure member 5 is set on one side of the seal 4 and applies force to the seal 4 to press the seal 4 against the outer end face of the flange 411, thereby preventing the connector 3 from moving in the direction of the inner end face of the flange 411, and realizing the sealed connection of the connector 3, the seal 4 and the interface portion 141.

[0034] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention.
