[0012] And / or, a filter is provided at the air inlet end of the air suction duct.

[0013] In some embodiments, the deodorizing urinal further comprises a nozzle, the nozzle being disposed at the top of the receiving groove and connected to an external water supply member;

[0014] In some embodiments, the nozzle is detachably mounted on the air suction assembly and is located between the air inlet end of the air suction duct and the rear wall of the receiving groove.

[0015] In some embodiments, the suction assembly includes a mounting plate, the suction duct and the fan are arranged on the mounting plate, the air inlet end of the suction duct is arranged on the lower end surface of the mounting plate, the mounting plate has a first step, and the top of the toilet body has a second step, and the first step of the mounting plate is arranged on the second step.

[0016] In some embodiments, the suction assembly further includes a deodorization module, which is disposed in the suction duct; and / or the distance between the fan and the deodorization module is L, 1mm<L<100mm.

[0040] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0043] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are used to refer to positions or locations based on those shown in the accompanying drawings. These terms are intended solely to facilitate description and simplify operation, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0044] like Figures 1 to 10 As shown, the present application provides a deodorizing urinal, which includes a toilet body 1, a nozzle 2 and an air suction assembly 3. The toilet body 1 has a receiving groove 11, the rear wall of the receiving groove 11 is recessed in the direction of the groove away from the receiving groove 11, and the bottom of the receiving groove 11 is provided with a sewage outlet 12; the nozzle 2 is provided at the top of the receiving groove 11, and the nozzle 2 is connected to an external water supply part so as to be able to flush water into the receiving groove 11; the air suction assembly 3 includes an air suction duct 31 and a fan 32, the fan 32 is provided at the air outlet end of the air suction duct 31, and the air inlet end of the air suction duct 31 is provided at the top of the receiving groove 11 so as to be able to suck air into the receiving groove 11.

[0045] When the user uses the deodorizing urinal of the above type normally, when urine hits the back wall of the deodorizing urinal, ammonia in the urine will be emitted everywhere. However, since the back wall of the urinal is concave, when the fan 32 in the suction assembly 3 draws air from the inner side of the receiving groove 11 through the suction duct 31, negative pressure will be generated at the air inlet end of the suction duct 31, and the ammonia will be guided by the concave surface of the back wall to rise to the air inlet end of the suction duct 31, which can reduce the possibility of ammonia being emitted toward the notch of the receiving groove 11, thereby improving the effect of suction and deodorization and enhancing the user experience.

[0046] In some embodiments, the rear wall of the receiving groove 11 is concave in an arc-shaped groove in the direction away from the groove opening, and the angle between the line between the high point of the top of the rear wall of the receiving groove 11 and the low point of the concave rear wall of the receiving groove 11 and the normal line in the vertical direction is a. Figure 2 As shown in the cross-sectional view, assuming that the highest point of the top of the rear wall of the receiving groove 11 is A, the lowest point of the depression of the rear wall of the receiving groove 11 is B, and the normal in the vertical direction is N, then the angle between the straight line AB and the straight line N is a, and the angle range is 0°<a<10°.

[0047] As shown in the following table, 0.5 ml of ammonia water was used for the test, with a concentration of 1%. Measurements were performed at five test points, namely, left 1, left 2, center, right 1, and right 2, at heights of 5 cm and 50 cm from the sewage outlet 12. Left 1 was closer to the rear wall of the receiving tank 11 than left 2, and right 1 was closer to the rear wall of the receiving tank 11 than right 2. The maximum concentration of the test point, the average concentration in the first 5 minutes and the average concentration in the first 10 minutes of operation of the fan 32, and the time taken for the concentration at the test point to be lower than 0.2 ppm were taken. The results are shown in the following table:

[0048]

[0049]

[0050]

[0051]

[0052]

[0053] Therefore, when the concentration is less than 0.2 ppm, the time taken is the least when a is 5°, and it will increase significantly when a is 10°. Therefore, the preferred angle is 5°, which has a better effect.

[0054] Since urine will flow from the rear wall of the receiving tank 11 to the sewage outlet 12, Figure 2As shown, in some embodiments, the air inlet end of the suction duct 31 is located between the vertical center line of the sewage outlet 12 and the rear wall of the receiving groove 11, so that the suction duct 31 can first absorb the airflow on the side close to the rear wall of the receiving groove 11, thereby forming a negative pressure on the side close to the rear wall of the receiving groove 11, and the airflow on the other side of the vertical center line of the sewage outlet 12 moves inward, thereby pushing the ammonia toward the rear wall, further reducing the possibility of ammonia going out of the groove, and further improving the deodorization effect.

[0055] like Figures 3 to 5 As shown, in some embodiments, the suction assembly 3 includes a mounting plate 33, and the suction duct 31 and the fan 32 are mounted on the mounting plate 33, such that the air inlet end of the suction duct 31 is disposed at the lower end surface of the mounting plate 33. Specifically, the suction duct 31 and the mounting plate 33 can be integrally formed, or the two can be formed separately, and can be connected by, but not limited to, screwing or snapping. For example, a fixing groove for mounting the fan 32 is provided at the end of the suction duct 31 away from the air inlet end to facilitate the fixing of the fan 32. The fan 32 can also be connected to the fixing groove by, but not limited to, screwing or snapping.

[0056] More specifically, if Figure 3 and Figure 5 As shown, the mounting plate 33 has a first step 34, and the top of the toilet body 1 has a second step 13. The first step 34 cooperates with the second step 13, and the mounting plate 33 is mounted on the second step 13 via the first step 34. To facilitate fixing, the lower end surface of the mounting plate 33 needs to face one side of the receiving groove 11 during installation. Both the mounting plate 33 and the toilet body 1 are provided with first mounting holes 35, and the first mounting member 36 secures the two through the first mounting holes 35. In the current embodiment, the first mounting hole 35 on the mounting plate 33 is a through hole, the first mounting hole 35 on the toilet body 1 is a threaded hole, and the first mounting member 36 is a bolt or screw. In the current embodiment, the air inlet end of the suction duct 31 is located at the lower end surface of the mounting plate 33. Therefore, during suction, the mounting plate 33 can block the airflow on the upper side of the mounting plate 33 from merging into the lower side of the mounting plate 33, reducing the possibility of turbulence. At the same time, in the current embodiment, the mounting plate 33 is fixed by cooperating with the first step 34 and the second step 13, thereby effectively blocking the airflow from the rear direction of the toilet body 1 from flowing into the side of the receiving groove 11 through the gap between the mounting plate 33 and the toilet body 1. In other words, both of the above methods can reduce the interference of the external airflow with the air inlet end of the suction duct 31 sucking the airflow inside the receiving groove 11, and can ensure the stability of the deodorization effect. In the current embodiment, in order to absorb the airflow in the receiving groove 11 as quickly as possible, the air inlet end of the suction duct 31 is arranged in a strip shape along the width direction of the rear wall of the receiving groove 11. In addition, the stepped installation method also makes the integration with the toilet body 1 higher and more beautiful.

[0057] like Figure 6 As shown, to further enhance the deodorization effect, in some embodiments, a deodorization module 37 is further provided within the suction duct 31. When the airflow carrying ammonia enters the suction duct 31, it is filtered by the deodorization module 37 and then discharged by the fan 32. In other words, the deodorization module 37 is provided on one side of the fan's suction port. The provision of the deodorization module 37 can adsorb ammonia and reduce odor emissions, while also protecting the fan 32 from the effects of gases such as ammonia, thereby extending the service life of the fan 32. For example, the deodorization module 37 can, but is not limited to, employ an activated carbon filter element. To facilitate the installation and replacement of the deodorization module 37 and reduce the installation process of the deodorization module 37, in the current embodiment, the deodorization module 37 is provided with a mounting frame. The deodorization module 37 is disposed within the mounting frame. The suction duct 31 includes a front air duct 311 and a rear air duct 312. The deodorization module 37 and part of the mounting frame are clamped between the front air duct 311 and the rear air duct 312. Specifically, a groove 313 is provided at the end of the front air duct 311, away from the air inlet end of the suction duct 31. The deodorizing module 37 and a portion of the mounting frame are embedded in the groove 313. At least two opposing first slots 314 are provided on the edge of the groove 313, as well as on the end of the rear air duct 312, away from the fan 32. The other end is provided with at least two corresponding first mounting ribs 315. The first mounting ribs 315 engage with the first slots 314, allowing the rear air duct 312 to press the deodorizing module 37 and a portion of the mounting frame against the groove 313. This plug-in connection eliminates the need for additional sealing. For further stability, both the front air duct 311 and the rear air duct 312 are provided with second mounting holes 316. Second mounting members 317 secure the two through the two second mounting holes 316. Furthermore, the mounting frame, exposed above the groove 313, is provided with first fixing holes, which allow it to be secured to the second fixing holes in the front air duct 311. Illustratively, one of the two second mounting holes 316 is a through hole and the other is a screw hole, and the second mounting member 317 is a bolt or screw. In the current embodiment, the front air duct 311 is integrally formed with the mounting plate 33; the fixing slot for fixing the fan 32 is provided on the rear air duct 312.

[0058] Furthermore, to reduce wind resistance, the effective flow area of ​​the fan 32's outlet is defined as SP, the effective flow area of ​​the air inlet on the front air duct 311 as S1, the effective flow area of ​​the inner cavity of the front air duct 311 as S2, and the effective flow area of ​​the inlet of the rear air duct 312 facing the deodorization module 37 as S3. Thus, S1>SP, S2>SP, and S3>SP, thereby minimizing wind resistance and noise. Furthermore, the deodorization module 37 is provided with multiple flow holes, the total area of ​​which is S4, where S4>SP, further reducing wind resistance. In the current embodiment, the effective flow area at any point in the suction duct 31 is greater than the effective flow area of ​​the fan 32's outlet.

[0059] It should be noted that in order to further reduce the resistance of the deodorization module 37, Figure 7 As shown, in the current embodiment, the distance L between the fan 32 and the deodorizing module 37 is 1 mm < L < 100 mm. This creates a transition area between the deodorizing module 37 and the fan 32, allowing the airflow to diffuse properly after passing through the deodorizing module 37. This reduces the flow rate and allows the airflow to enter the fan 32 more smoothly and evenly. This improves air suction efficiency while also reducing energy consumption and noise and extending the life of the fan 32.

[0060] like Figure 2 As shown, in some embodiments, the air outlet of the fan 32 is positioned downward, thereby directing the airflow to the foot area, preventing the airflow from flowing upward and improving the user experience. In some embodiments, to ensure a concealed effect, an air duct is provided on the toilet body 1, and an air guide outlet is provided at the lower end of the toilet body 1. The air outlet of the fan 32 is connected to the air duct to reduce exposure. It is understood that in other embodiments, the toilet body 1 can also be provided without an air duct, ensuring that the air outlet of the fan 32 is directly facing downward.

[0061] In some embodiments, a filter is installed at the air inlet end of the suction duct 31 to filter out dust and other impurities, preventing clogging with debris such as paper towels and cigarettes, while also extending the life of the deodorizing module. In the current embodiment, the filter is removably installed at the air inlet end of the suction duct 31, allowing it to be removed for cleaning. For example, the filter can be secured by, but is not limited to, snap-on, plug-in, or screw-on methods.

[0062] like Figure 5 As shown, in some embodiments, the nozzle 2 is detachably mounted on the suction assembly 3, thereby facilitating the assembly and disassembly of the nozzle 2. Specifically, the nozzle 2 is mounted on the lower end surface of the mounting plate 33, thereby being able to hide the nozzle 2 and improve the aesthetics. Figure 8 and Figure 9As shown, one of the nozzle 2 and the mounting plate 33 is provided with a second slot (not shown in the figure), and the other is provided with a second mounting rib 23. The second mounting rib 23 can be inserted into the second slot, thereby fixing the nozzle 2 and the mounting plate 33. In the current embodiment, one end of the second mounting rib 23 also protrudes with a plug-in buckle 231, and the mounting plate 33 is provided with a buckle groove, so that it can be buckled to further improve stability. Of course, as Figure 6 and Figure 8 As shown, the nozzle 2 and the mounting plate 33 can also be provided with a third mounting hole 24, and the third mounting member 25 can fix the nozzle 2 and the mounting plate 33 through the third mounting hole 24. One of the two third mounting holes 24 is a screw hole and the other is a through hole. The third mounting member 25 can be a bolt or a screw.

[0063] In the current embodiment, the nozzle 2 is located between the air inlet end of the suction duct 31 and the rear wall of the receiving tank 11, making it easier for the nozzle 2 to clean the rear wall of the receiving tank 11. In the current embodiment, the nozzle 2 faces the rear wall of the receiving tank 11, thereby improving the cleaning effect. To further enhance the cleaning effect, the nozzle 2 has a first channel 21 and a second channel 22 that are not interconnected, allowing disinfectant to be supplied through the first channel 21. The second channel 22 is used to supply cleaning water, allowing it to be used in conjunction with the disinfectant to enhance the cleaning effect. Furthermore, the first channel 21 and the second channel 22 do not interfere with each other and do not affect the flushing effect of each separately. The outlets of the first channel 21 and the second channel 22 can be, but are not limited to, bar-shaped. It should be noted that the disinfectant can be a finished disinfectant, such as 84 disinfectant. The deodorizing urinal can also include a liquid tank for storing the disinfectant, which is connected to the nozzle 2. To reduce the need for disinfectant replenishment and lower costs, the disinfectant used in the current embodiment is electrolyzed water. Electrolyzed water has a disinfecting and sterilizing function, and its sterilizing effect primarily comes from active substances such as hypochlorous acid generated by electrolysis. The deodorizing urinal in this embodiment further includes an electrolytic water assembly (not shown in the figure), which is connected to the nozzle 2. The electrolytic water assembly is a commonly used component in the prior art and will not be described in detail.

[0064] like Figure 3 and Figure 10As shown, in some embodiments, a panel 4 is provided on the top of the toilet body 1. The panel 4 covers the suction assembly 3, thereby shielding the suction assembly 3 and ensuring aesthetics. Placing the panel 4 on the top of the toilet body 1 also facilitates maintenance. The panel 4 can be secured to the toilet body 1 by screwing or snapping. Furthermore, a sensor 5 is provided on the panel 4. The sensor 5 is connected to the fan 32 and nozzle 2 via a control element 7 provided on the panel 4, thereby controlling the start and stop of the fan 32 and nozzle 2 according to the user's approach or departure. For example, the sensor 5 can be, but is not limited to, a distance sensor. The panel 4 is provided with a socket 41, into which the sensor 5 plugs. In the current embodiment, placing the sensor 5 on the panel 4 avoids placing it directly on the toilet body 1, thereby reducing the impact of vibration caused by the start and stop of the fan 32 and nozzle 2. It should be noted that the control element 7 is a commonly used control element in the related art and will not be described in detail. For example, the panel 4 can be made of acrylic.

[0065] like Figure 2 As shown, in some embodiments, a footprint spotlight 6 is also provided on the toilet body 1, which is arranged at the bottom of the toilet body 1. The footprint spotlight 6 is still controlled and connected through the above-mentioned control component 7, so that the footprint position can be projected on the ground before use, guiding the user to use the distance, and further improving the use experience.

[0066] In addition, in order to further enhance the user experience, the panel 4 may have a display panel 8 so as to display various states, for example, deodorization display, electrolyzed water flushing display, pure water flushing display, etc.

[0067] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
