Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sanitary ware, in particular to a deodorizing urinal with a negative pressure zone in front of the urinal. Background Art
[0002] The large amount of ammonia molecules in urine is the main factor causing the urine to produce odor. The molecular weight of ammonia is only 17, while the average molecular weight of the atmosphere is about 29. Therefore, ammonia is quickly released in the air and basically evaporates upward. Therefore, the longer the urine is exposed to the air, the more ammonia evaporates. When there are many people urinating in the restroom, even if each person evaporates a small amount of ammonia, the ammonia smell in the entire restroom is very obvious, which leads to a stronger odor.
[0003] The main reasons why public toilets produce particularly severe urine odor are:
[0004] 1. The sewage replacement method of the urinal is unscientific. The bottom of the urinal seems to have no water, but there is actually a larger entrance platform under the movable cover. The diameter of the water trap of the urinal is only 23 mm. When people stand in front of the urinal, the sensor will immediately start flushing. Due to the small diameter and slow flow rate, water and urine will stay briefly on this entrance platform. The urine pulled out later will directly flush the urine on the entrance platform, constantly stirring the original urine and accelerating the volatilization of ammonia in the urine. People normally urinate for 25-35 seconds. During this period, the urinal is not flushed in the middle. Only the new urine stirs the old urine to help it quickly volatilize ammonia. The longer the urination time, the longer the urine is exposed to the air, and the faster the ammonia is released. When the urine is pulled in the basin for 10 seconds, the ammonia index detected above the basin mouth is only 39. When people urinate for 35 seconds, the ammonia index rises to 907, that is to say: within a time interval of 25 seconds, the ammonia index released from the urine has increased by 30 times. In real life, all urinals only start flushing after people finish urinating and leave the sensor valve. At this time, a large amount of ammonia in the urine has been released into the bathroom. However, people do not have enough knowledge about the urine odor produced during the urination process, and do not know that the subsequent flushing can only ensure that no more urine releases ammonia.
[0005] 2. The air replacement method of the bathroom is unscientific. Public toilets are generally located in places with concentrated traffic, and the building facilities are very crowded, so it is difficult for the air in public toilets to achieve natural air convection. In high-end airport and high-speed rail station public toilets, there are full-time sanitation staff who are constantly cleaning, and some toilets have high-power fans blowing air constantly. However, the air in the toilet is always circulating internally, so it is always full of urine smell.
[0006] Therefore, in the related art, urinals use items with volatile odors, such as mothballs, to cover up odors. However, this method cannot effectively remove odors and cannot achieve an odor-free use environment for the urinal. Utility Model Content

[0036] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0037] like Figure 1 As shown, the deodorizing urinal with negative pressure zone in front of the bucket of the embodiment of the utility model comprises a device body 1, a cover body 2 and a negative pressure component; the device body 1 has a bucket groove 101; the cover body 2 forms a chamber 201, and the cover body 2 is provided with a first connecting port 202 and a second connecting port 203, the first connecting port 202 connects the chamber 201 with the upper part of the bucket groove 101, and the second connecting port 203 connects the chamber 201 and the negative pressure component; the negative pressure component is used to evacuate air to form a negative pressure zone in the upper part of the bucket groove 101.
[0038] Specifically, when the negative pressure component is working, it can extract the gas in the chamber 201, and the chamber 201 is connected to the upper part of the bucket 101, thereby, a negative pressure area will be formed in the upper part of the bucket 101. In actual application, the ammonia volatilized from the urine will be discharged in the negative pressure area along with the air flow through the first connecting port 202, the chamber 201, the second connecting port 203 and the negative pressure component. Therefore, the ammonia will not be retained in the bucket 101, and an odor-free use environment of the urinal can be achieved.
[0039] The cover body 2 has a first communication port 202 , and the exhaust efficiency of ammonia gas can be improved by properly setting the direction of the first communication port 202 .
[0040] Among them, the negative pressure component includes an exhaust pipe 3 and an exhaust device 4; the exhaust pipe 3 has an input pipe port and an output pipe port; the exhaust device 4 is used to generate an airflow from the input pipe port to the output pipe port in the exhaust pipe 3 to achieve exhaust.
[0041] The deodorizing urinal with negative pressure zone in front of the bucket of the present application utilizes the property that ammonia gas rises because its density is lower than that of natural air. The directional negative pressure generated by the cover body 2, the exhaust pipe 3 and the exhaust device 4 above the bucket trough 101 forms a negative pressure zone in front of the bucket in the open area above the bucket trough 101, so that ammonia gas volatilized from urine when people urinate is discharged outdoors along with the negative pressure air flow through the cover body 2 and the exhaust pipe 3 in the negative pressure zone in front of the bucket, thereby ensuring the automatic deodorizing effect of the urinal at any time.
[0042] In addition, the negative pressure area is generated based on the cover body 2, the exhaust pipe 3 and the exhaust device 4, and the ammonia gas is completely exhausted regardless of whether it is concentrated or not. The equipment is simple, low in cost, durable and easy to maintain.
[0043] In this embodiment, the cover body 2 is integrally formed with the device body 1, and the cover body 2 is located above the bucket groove 101. The cover body 2 of this structure is simple in structure and easy to process. At this time, the cover body 2 is equivalent to a windshield plate arranged above the notch of the bucket groove 101.
[0044] In actual application, when the urinal is in use, urine is concentrated at the bottom of the bucket 101, while ammonia evaporates upward. Therefore, as a preferred embodiment of this embodiment, the first connecting port 202 is downwardly connected to the bucket 101. At this time, the airflow generated by the operation of the exhaust device 4 also enters the chamber 201 upward in the bucket 101, that is, the flow direction of the airflow in the bucket 101 is the same as the volatilization direction of the ammonia, which is conducive to the airflow driving the ammonia into the exhaust pipe 3 and discharged through the exhaust pipe 3, and the ammonia discharge efficiency is high.
[0045] Furthermore, the second connecting port 203 penetrates from the inner wall surface of the chamber 201 to the outer wall surface of the device body 1, and the input pipe port is connected to the outer wall surface of the device body 1; the second connecting port 203 of this structure is simple in structure and is also convenient for installing the exhaust pipe 3.
[0046] Among them, Figure 1 and Figure 2 As shown, the outer wall surface may be the top wall surface or the side wall surface of the device body 1, and this embodiment does not impose any limitation on this.
[0047] As one of the implementation methods of this embodiment, Figure 1 As shown, the exhaust device 4 is a fan, which is connected to the inner wall surface of the chamber 201 and covers the second connecting port 203, so that when the exhaust device 4 is working, an air flow in the above-mentioned direction can be formed in the exhaust pipe 3; and the exhaust device 4 is located in the chamber 201, which makes full use of the space of the chamber 201 and makes the structure of the urinal more compact.
[0048] As another implementation of this embodiment, Figure 2 As shown, the exhaust device 4 is a fan, which is connected to the outer wall surface of the device body 1 and covers the second connecting port 203, and the exhaust pipe 3 covers the exhaust device 4 therein, thereby, when the exhaust device 4 is working, an airflow in the above-mentioned direction can also be formed in the exhaust pipe 3; and the exhaust device 4 is arranged on the outer wall surface of the device body 1, wherein the outer wall surface can be the top wall surface or the side wall surface of the device body 1, and during installation, the operator can intuitively observe the installation position of the exhaust device 4, thereby, the installation operation of the exhaust device 4 is relatively simple.
[0049] Specifically, no matter which of the above implementation methods is used, the number of fans can be one or more, and the power supply of the fans can be AC or DC, which is not limited in this application.
[0050] In this embodiment, if Figure 1 As shown, the deodorizing urinal with negative pressure area in front of the bowl also includes a sewage pipe 5; and the main body 1 has a water trap channel 102, which is located below the bowl 101, and the water inlet of the water trap channel 102 is connected to the bottom of the bowl 101, and the water outlet of the water trap channel 102 is connected to the sewage pipe 5, and urine is discharged through the sewage pipe 5. In actual application, a water seal is formed in the water trap channel 102, which can prevent sewage from flowing back and isolate odor. It is a prior art and this embodiment will not be described in detail.
[0051] Furthermore, the deodorizing urinal in the negative pressure area in front of the bowl also includes a one-way valve 6, which is arranged on the exhaust pipe 3, and the output pipe port is connected to the sewage pipe 5; specifically, the flow direction of the one-way valve 6 is from the input pipe port to the output pipe port, that is, the one-way valve 6 can allow air to pass through, but cannot allow sewage in the sewage pipe 5 to pass through; and the output pipe port of the exhaust pipe 3 is connected to the sewage pipe 5, and the sewage pipe 5 can discharge sewage and ammonia, which is beneficial to the centralized treatment of sewage and ammonia, making the surrounding air cleaner.
[0052] Regarding the arrangement of the outlet of the exhaust pipe 3, in other embodiments, as Figure 2 As shown, the output pipe opening is connected to the atmosphere, wherein the output pipe opening extends outside the toilet where the urinal with negative pressure zone deodorization in front of the bowl of the utility model is applied. At this time, the exhaust pipe 3 directly discharges ammonia into the atmosphere, which can also achieve an odor-free use environment for the urinal.
[0053] In this embodiment, if Figure 1 As shown, the cover body 2 has a front side surface 204, and the front side surface 204 and the notch of the bucket groove 101 are located on the same side of the device body 1; the front-bucket negative pressure zone deodorizing urinal also includes a sensor 7 and a controller (not shown in the figure), the sensor 7 is arranged on the front side surface 204, and the sensor 7 and the exhaust device 4 are electrically connected to the controller; the controller is configured to control the start and stop of the exhaust device 4 according to the signal of the sensor 7; specifically, the sensor 7 can be an infrared sensor 7 or a sensor 7 well known to those skilled in the art; illustratively, when the sensor 7 senses that someone is within 0.8 meters of the urinal, the sensor 7 generates a first signal and transmits the first signal to the controller, and the controller controls the exhaust device 4 to start, thereby generating an airflow in the exhaust pipe 3, so that the ammonia volatilized in the urinal can be discharged; and when the sensor 7 does not sense that someone is within 0.8 meters of the urinal, the sensor 7 generates a second signal and transmits the second signal to the controller, and the controller controls the exhaust device 4 to be in a stopped state.
[0054] The sensor 7 is arranged on the front side surface 204 of the cover body 2, and the front side surface 204 and the notch of the bucket groove 101 are located on the same side of the device body 1, so that the sensor 7 is easy to repair and maintain. Moreover, the distance between the sensor 7 and the human body is relatively close, and the sensitivity of the sensor 7 is higher, which is beneficial to improve the discharge effect of ammonia.
[0055] In addition, in actual applications, the flushing system and control system of the urinal are both consumable parts, and maintenance is a frequent occurrence. In the related art, for the convenience of maintenance, most urinals are designed with a separate cover on the top, and a special screw is also provided to prevent idle people from opening the cover at will. In addition to being troublesome to operate and affecting the appearance, more importantly, this cover brings extremely complex process difficulties to ceramic processing. Few covers match the size, few are not deformed, and even fewer are not exposed to glaze. There are also some that simply do not make a cover for the simplicity and beauty of the urinal. If there is a problem with the urinal waterway or the sensor fails, the entire urinal can only be disassembled and reinstalled. In this application, the chamber 201 and the first connecting port 202 of the cover body 2 are designed to be larger. Therefore, an equipment maintenance hole can be opened at any position in the cover body 2 to facilitate timely maintenance of the urinal water supply system or sensor failure.
[0056] Regarding the control method of the operation of the air extraction device 4, in other embodiments, the deodorizing urinal in the negative pressure area before the bowl is not provided with the sensor 7, and the controller is electrically connected to the air extraction device 4, and the controller controls the intermittent start and stop of the air extraction device 4, that is, the controller controls the operation of the air extraction device 4 at a fixed time; or, the start and stop of the air extraction device 4 are controlled by manually operating the controller; the above methods realize the operation of the air extraction device 4, which can realize the use environment of the urinal without odor, and the present utility model does not impose any limitation on this.
[0057] Regarding the structure of the cover body 2, in other embodiments, the cover body 2 is block-shaped and is suspended on the upper part of the bucket 101. Thus, an odor-free use environment of the urinal can also be achieved. The advantage of the cover body 2 with this structure is that the layout position of the cover body 2 can be flexibly set, which is conducive to adjusting the discharge efficiency of ammonia.
[0058] In practical applications, the height of the design position of the cover body 2 is flexibly adjusted by the size of the urinal bowl 101, and the appearance design of the cover body 2 is not limited. The number of chambers of the cover body 2 can be one or more, and the present application does not impose any restrictions on this.
[0059] Regarding the arrangement of the exhaust device 4, in other embodiments, the exhaust device 4 is connected to the output pipe port. Therefore, when a large number of deodorizing urinals with negative pressure zones in front of the bowl are provided in the toilet, one exhaust device 4 can be provided, and the exhaust pipes 3 of each urinal are all connected to the exhaust device 4. The ammonia in each urinal is discharged through one exhaust device 4, which is beneficial to saving installation costs.
[0060] In the present invention, the deodorizing urinal in the negative pressure zone in front of the bowl can be a floor-standing urinal, a wall-mounted urinal or other styles of urinals, and the present invention does not limit this; and the above-mentioned bowl 101 refers to a urinal bowl.
[0061] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
