Description

Technical Field

[0001] This utility model relates to the field of odorless toilet technology, specifically to a suction and discharge device and a toilet having the suction and discharge device. Background Technology

[0002] Currently, toilet deodorization relies on exhaust fans at the top of the bathroom ceiling. However, the toilet itself, the source of the odor, is located at the bottom of the bathroom. During the deodorization process, the gas first fills the bathroom from bottom to top before exiting through the exhaust fan, leaving people with a lingering stench. Some have proposed installing a fan and suction / exhaust connector at the rear of the toilet. The connector has an air intake and a water outlet. The air intake connects to the fan, using the negative pressure generated to draw in the odor and discharge it into the sewer, reducing the smell. The water outlet connects to the water tank or the municipal water supply, flushing the toilet's drain surface. For squat toilets, the existing outlet structure is inadequate, requiring multiple water outlets around the top of the drain surface to wash it, increasing water loss and hindering cleaning. As for urinals, current models lack effective deodorization measures, making it difficult to eliminate the stench emanating from them. Summary of the Invention

[0003] The purpose of this utility model is to provide a suction and discharge device and a toilet with the suction and discharge device, which can better deodorize the toilet and also take into account its flushing effect.

[0004] To achieve the above objectives, the technical solution of this utility model includes:

[0005] A suction and exhaust device includes a suction and exhaust connector for installation on a toilet. The suction and exhaust connector has a suction channel and a drain channel. The two ends of the suction channel are a suction port and an exhaust port, respectively. The exhaust port is connected to a fan. By means of the negative pressure generated by the rotation of the fan, the suction port is used to draw in air from inside the toilet body using the negative pressure. The two ends of the drain channel are a spray outlet and a water inlet, respectively. The water inlet is connected to a water inlet pipe, and the spray outlet is used to spray water from the water inlet pipe onto the drain surface of the toilet to flush the drain surface.

[0006] In one embodiment, the suction and exhaust connector includes a suction and exhaust section and a cylindrical mounting section. With the axial direction of the mounting section as the front-rear direction, the end where the suction and exhaust section is located is the front, and the opposite direction is the rear. The exhaust port and the water inlet are located at the rear end of the mounting section, and the suction port and the spray water outlet are located at the front end of the suction and exhaust section. The upper end of the suction and exhaust section is provided with a downward and forward-extending baffle.

[0007] In one embodiment, on a plane perpendicular to the front-back direction, the outer contour of the suction and exhaust portion is arc-shaped, and the lower edge of the suction and exhaust portion is provided with a slit extending along its arc-shaped outer contour direction. The slit forms the spray outlet, thereby the air intake is located above the spray outlet.

[0008] In one embodiment, the outer wall of the mounting portion forms a fan mounting structure, the drainage channel is located on the lower inner side of the mounting portion, the rear end of the drainage channel protrudes rearward relative to the fan mounting structure to form a water pipe mounting structure, the water pipe mounting structure is surrounded within the fan mounting structure, and the fan is provided with a through hole for the water inlet pipe to pass through.

[0009] In one embodiment, the lower half of the suction and exhaust portion is provided with a reinforcing plate, which is located below and behind the lower edge of the shielding plate. The reinforcing plate is provided with a plurality of openings, which are used to selectively form a water jet outlet or a part of the air intake. The shielding plate is provided with a cleaning port, which is connected to the air intake channel.

[0010] In one embodiment, the reinforcing sheet is an arc-shaped sheet structure. The reinforcing sheet has a first opening in the middle, a second opening on the left and right sides of the first opening, a third opening below the first opening, which is formed through the gap between the lower edge of the reinforcing sheet and the lower edge of the suction and discharge part, and a fourth opening above the first opening, which is formed through the gap between the lower edge of the shielding sheet and the upper edge of the reinforcing sheet.

[0011] In one embodiment, the shielding plate has a fifth opening, and a guide plate extending axially along the suction and discharge joint is provided in the fifth opening.

[0012] In one embodiment, the inner side of the mounting part is provided with a cylindrical channel, and the air intake and the water jet outlet are both connected to the cylindrical channel. The cylindrical channel selectively forms the air intake channel and the drainage channel, so that the exhaust port and the water inlet are shared, and are connected to the fan and the water inlet pipe through an air-water separation connector.

[0034] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0035] Example 1

[0036] See Figures 1 to 6 As shown, this utility model discloses a suction and exhaust device, including a suction and exhaust connector 1 for installation on a toilet. The suction and exhaust connector 1 has a suction channel 11 and a drain channel 12. The two ends of the suction channel 11 are a suction port 111 and an exhaust port 112, respectively. The exhaust port 112 is connected to a fan 2. With the help of the negative pressure generated by the rotation of the fan 2, the suction port 111 is used to draw in air from the toilet body 100 using the negative pressure. The two ends of the drain channel 12 are a spray outlet 121 and a water inlet 122, respectively. The water inlet 122 is connected to a water inlet pipe, and the spray outlet 121 is used to spray water from the water inlet pipe onto the drain surface 101 of the toilet to flush the drain surface 101.

[0037] This invention integrates the air intake channel 11 and the drainage channel 12 into the suction and discharge connector 1, combining the deodorization and flushing functions of the toilet. When used as a urinal, it adds a deodorization function, enhancing the user experience. Furthermore, the spray nozzle 121 sprays water onto the drain surface 101 of the toilet to flush it. Compared to existing squat toilets where water is discharged from the top of the drain surface, this invention reduces water loss during its journey to the drain surface, thus improving the flushing effect.

[0038] The suction / exhaust connector 1 includes a suction / exhaust section 13 and a cylindrical mounting section 14. With the axial direction of the mounting section 14 as the front-to-back direction, the end containing the suction / exhaust section 13 is considered the front, and the opposite direction is considered the rear. An exhaust port 112 and a water inlet 122 are located at the rear end of the mounting section 14, while an air intake port 111 and a water jet outlet 121 are located at the front end of the suction / exhaust section 13. This arrangement allows both the air intake channel 11 and the drainage channel 12 to extend in the front-to-back direction. Only the front suction / exhaust section 13 needs to be exposed, while the rear mounting section 14 and structures such as the fan can be concealed inside the toilet bowl body. Figure 7 and Figure 12 The air intake 111 is positioned above the water jet outlet 121 to prevent water from entering the air intake channel 11 from the air intake 111 when air intake and drainage are performed simultaneously.

[0039] The upper end of the suction and exhaust section 13 is provided with a downward and forward extending baffle 15. The lower edge of the baffle 15 protrudes forward, thus forming an air intake 111 at its lower end. The baffle 15 serves two purposes: firstly, it guides the airflow, allowing the negative pressure generated by the fan to draw upwards and absorb odors from the toilet bowl. Especially for urinals, where the suction and exhaust connector 1 is installed at the upper end, the guiding effect of the baffle 15 can create an upward airflow for the odors in the urinal, which is beneficial for improving the odor removal effect; secondly, the baffle 15 can also cover the air intake channel 11, making the installation of the suction and exhaust connector 1 in the toilet bowl more aesthetically pleasing.

[0040] In this embodiment, the shielding plate 15 has an arc-shaped structure, which is more aesthetically pleasing and easier to clean. In other embodiments, the shielding plate 15 is not limited to an arc shape; it can also be a slope that gradually tilts forward from top to bottom.

[0041] On a plane perpendicular to the front-to-back direction, the outer contour of the suction and discharge section 13 is arc-shaped, and the lower edge of the suction and discharge section 13 is provided with a slit extending along its arc-shaped outer contour, forming a jet outlet 121. The arc-shaped jet outlet 121 can form a fan-shaped water flow, which gradually spreads to cover the sewage discharge surface 101 during the flow process, thereby cleaning the sewage discharge surface.

[0042] In this embodiment, the outer contour of the suction and discharge portion 13 is circular. In other embodiments, the lower edge contour of the suction and discharge portion 13 is arc-shaped, and the upper edge contour of the suction and discharge portion 13 is elliptical arc-shaped, so that the outer contour of the suction and discharge portion 13 is formed as an arc-shaped structure spliced ​​by arc and elliptical arc.

[0043] See Figure 3 and Figure 6As shown, the outer wall of the cylindrical mounting portion 14 forms a fan mounting structure 141, and a drainage channel 12 is provided on the lower inner side of the mounting portion 14. The rear end of the drainage channel 14 protrudes rearward relative to the fan mounting structure 141 to form a water pipe mounting structure 142, which is enclosed within the fan mounting structure 141. Furthermore, to facilitate the connection of the water inlet pipe to the water pipe mounting structure 142, the fan 2 has a through hole 21 for inserting the water inlet pipe. The water inlet pipe passes through the through hole 21 of the fan 2 and is inserted into the water pipe mounting structure 142. In this embodiment, the water inlet pipe is a flexible hose made of silicone or rubber, and the water pipe mounting structure 142 has multiple annular positioning protrusions to form an interference fit with the water inlet pipe to fix it in place.

[0044] Example 2

[0045] See Figure 7 As shown, this embodiment discloses a toilet, specifically a urinal, which includes a toilet body and a suction / discharge device. The structure of the suction / discharge device in this embodiment is the same as that in Embodiment 1, and will not be described again here. The suction / discharge connector 1 of the suction / discharge device is installed in the middle of the rear end of the urinal. For the urinal, the middle of the rear end is the upper middle position of the sewage discharge surface 101. The fan 2 and water inlet pipe are hidden inside the urinal, with only the suction / discharge part 13 of the suction / discharge connector 1 exposed.

[0046] Example 3

[0047] See Figures 8 to 11 As shown, this embodiment is a suction and exhaust device, which has the same function as Embodiment 1, also used for suctioning and exhausting odors and flushing water from a toilet. The difference from Embodiment 1 is that this suction and exhaust device is more suitable for squat toilets. Figure 12 ).

[0048] The suction and discharge connector 1 in this embodiment is also provided with a suction channel 11 and a drainage channel 12. The difference is that the suction port 111 and the spray outlet 121 in this embodiment are both composed of multiple openings, and the suction channel 11 and the drainage channel 12 are shared. When the fan 2 is working, it is used as the suction channel 11, and when flushing (i.e. when water comes out of the inlet pipe), it is used as the drainage channel 12. Correspondingly, the suction port 111 and the spray outlet 121 are also shared.

[0049] The lower half of the suction / exhaust section 13 is provided with a reinforcing plate 16, which is located below and behind the lower edge of the baffle plate 15. The reinforcing plate 16 has multiple openings 160, which are used to selectively form part of the spray nozzle 121 or the air intake 111. Specifically, the reinforcing plate 16 is an arc-shaped sheet structure. A first opening 161 is provided in the middle of the reinforcing plate 16, a second opening 162 is provided on the left and right sides of the first opening 161, and a third opening 163 is provided below the first opening 161. The third opening 163 is formed through the gap between the lower edge of the reinforcing plate 16 and the lower edge of the suction / exhaust section 13. At this time, the lower edge of the baffle plate 15 protrudes forward, thereby forming a fourth opening 164 in the gap between its lower edge and the upper edge of the reinforcing plate 16. This fourth opening 164 can selectively form part of the air intake 111 or part of the spray nozzle 121. The inner side of the mounting section 14 is provided with a cylindrical channel. The air intake 111 and the water jet outlet 121 are both connected to the cylindrical channel. The cylindrical channel selectively forms the air intake channel 11 and the drainage channel 12, so that the exhaust port 112 and the water inlet 122 are shared. Specifically, the suction and exhaust section 13 is provided with a connecting piece 17 connected to the mounting section 14. The shielding piece 15 and the reinforcing piece 16 are both connected to the connecting piece 17. The connecting piece 17 is provided with a connecting hole that connects to the mounting section 14. The connecting hole selectively forms part of the air intake channel 11 and the drainage channel 12, so that the exhaust port 112 and the water inlet 122 are shared (i.e., the rear end opening of the mounting section 14), and is connected to the fan 2 and the water inlet pipe through an air-water separation connector 200.

[0050] Since the air intake channel 11 and the drainage channel 12 are shared, the gas-liquid separator connector 200 should have mutually isolated gas channels 201 and liquid channels 202 for connecting the fan 2 and the water inlet pipe. The fan 2 and the water inlet pipe can be connected to the gas channels 201 and the liquid channels 202 respectively via pipes, thus the fan 2 is indirectly connected to the exhaust port 112, and the water inlet pipe is indirectly connected to the water inlet 122. It should be noted that the gas-liquid separator connector 200 is prior art. Figure 11 The structure shown in the dashed lines is not limited to the structure shown in the dashed lines. The specific structure of the gas-water separation connector 200 refers to the gas-water separation connector of CN219175408U and other existing technologies. That is, the suction and discharge connector of this embodiment can be used with the gas-water separation device of CN219175408U to realize the suction and discharge of odor and the spray flushing. Although the names of the relevant components in the prior art are different from those of this utility model, they can also achieve the function of gas-water separation.

[0051] When the suction and discharge device of this embodiment is used to flush a squat toilet, the water in the inlet pipe passes through the connecting holes of the mounting part 14 and the connecting piece 17 in sequence to reach the suction and discharge part 13, and thus the first opening 161, the second opening 162, the third opening 163 and the fourth opening 164 of the suction and discharge part 13 are dispersed and sprayed out. At this time, the first opening 161, the second opening 162, the third opening 163 and the fourth opening 164 work together to form the spray outlet 121, and the channel in the suction and discharge connector 1 forms the drainage channel 12. The first opening 161 is located in the middle of the reinforcing plate 16, close to the axial extension line of the connecting hole of the connecting plate 17. Therefore, a large amount of water is sprayed out from the first opening 161, and the water sprayed out from the first opening 161 has a large kinetic energy, which can form the main flushing water flow. When used in a squat toilet, it can spray to the front of the toilet's drain surface. The second opening 162 is located on the left and right sides and is at the same height as the first opening 161. A portion of the water flow is sprayed out from the second opening 162 to flush the left and right sides of the drain surface. In addition, the water flow blocked by the reinforcing plate 16 flows out from the third opening 163 and the fourth opening 164 on the upper and lower sides of the first opening 161. Due to the blocking by the reinforcing plate 16, the water flow from the third opening 163 and the fourth opening 164 is less and has less kinetic energy. It is mainly used to flush the rear of the drain surface and also increases the water flow for flushing the drain surface. Therefore, in this embodiment, multiple openings 160 (first opening 161, second opening 162, third opening 163 and fourth opening 164) are provided in the suction and discharge section 13. This can not only disperse the water flow to increase the flushing area, but also allow a portion of the water flow to be sprayed with greater kinetic energy onto the front half of the sewage discharge surface 101 and cover the entire sewage discharge surface 101, thereby improving the flushing effect.

[0052] In addition, the baffle plate 15 is provided with a slit-shaped cleaning port 151, which can clean contaminants on the suction device body when the squat toilet is drained. At the same time, 151 can also serve as an air inlet, which is connected to the air intake channel 11. Therefore, the air inlet is formed as part of the air intake 111, increasing the air intake volume and improving the deodorization effect.

[0053] When the suction and exhaust device of this embodiment is used to exhaust odors from a squat toilet, the blower generates negative pressure. Air from the toilet's drain surface is drawn in through the air inlet (i.e., cleaning port 151), the first opening 161, the second opening 162, the third opening 163, and the fourth opening 164. The air then passes sequentially through the suction and exhaust section 13 and the connecting hole of the connecting piece 17 to the mounting section 14, and then through the air-water separation connector 200 at the rear end of the mounting section 14 into the blower 2. The blower 2's outlet is connected to the drain pipe, thereby discharging the odors into the drain pipe.

[0054] The remaining undescribed parts are the same as in Example 1.

[0055] Example 4

[0056] See Figure 12and Figure 13 As shown, the suction and discharge connector of this embodiment is similar to that of embodiment 3. The difference between this embodiment and embodiment 3 is that the structure of the air intake 111 and the water jet outlet 121 is different from that of embodiment 3.

[0057] The shielding plate 15 has a fifth opening 165, and a guide plate 18 extending along the axial direction of the suction and discharge joint 1 is provided inside the fifth opening 165. The presence of the guide plate 18 can guide the water flow and air flow in the fifth opening 165. Since the guide plate 18 extends along the axial direction of the suction and discharge joint 1, it can guide the water flow and air flow along the axial direction of the suction and discharge joint 1, increase the distance of the water flow sprayed to the sewage discharge surface 101, and also improve the effect of odor suction and discharge.

[0058] In addition, another difference between this embodiment and embodiment 3 is that the structure and position of the cleaning port 151 are different. In this embodiment, the cleaning port 151 is located above the middle of the shielding plate 15.

[0059] Example 5

[0060] See Figure 14 As shown, this embodiment discloses a toilet, specifically a squat toilet, which includes a toilet body and a suction / discharge device. The structure of the suction / discharge device in this embodiment is the same as that in Embodiment 3 or Embodiment 4, and will not be described again here. The suction / discharge connector 1 of the suction / discharge device is installed in the middle of the rear end of the squat toilet. For a squat toilet, the middle of the rear end is the upper middle position of the sewage discharge surface 101. The suction / discharge portion 13 of the suction / discharge connector 1 protrudes from the sewage discharge surface 101 of the squat toilet.

[0061] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that the remaining undescribed parts are prior art, and that all changes in form and detail made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims fall within the protection scope of the present invention.
