Description

Technical Field

[0001] The present invention relates to the field of vacuum sewage collection, transportation and treatment technology, wherein vacuum sewage collection technology refers to a front-end device or product for collecting sewage at the sewage source, including but not limited to various kitchens (such as toilets, urinals, shower rooms, bathtubs, etc.) and sanitary products (such as vegetable sinks, dishwashers, etc.); vacuum sewage transportation technology refers to the relevant technology of efficiently transporting sewage collected by front-end devices or products to sewage post-treatment equipment; vacuum sewage treatment technology refers to post-treatment equipment or devices, the main function of which is to separate and purify the centralized collected sewage into solids and liquids, wherein the solids can be made into organic fertilizers, and the sewage can be filtered and purified by MBR membrane technology to achieve green discharge. The present invention particularly relates to a vacuum toilet with odor extraction, detoxification and noise reduction functions. Background Art

[0002] In the field of vacuum domestic sewage collection, transportation and treatment technology, vacuum domestic sewage collection is the most advanced technology. Its basic implementation principle is as follows: First, the sewage collection inlet pipeline (or sewage discharge inlet pipeline) in the vacuum sewage transportation system is connected to various sewage front-end collection equipment, including but not limited to various kitchens (such as toilets, urinals, shower rooms, bathtubs, etc.) and sanitary products (such as vegetable sinks, dishwashers, etc.); secondly, the vacuum pump group generates vacuum in the vacuum sewage transportation system; finally, during the operation of the sewage front-end collection equipment, after the vacuum sewage valve is connected, the pressure difference between the external atmospheric pressure and the vacuum value inside the pipeline in the vacuum sewage transportation system is applied to the sewage and mixed with air to realize turbulent transportation of sewage to the sewage collection inlet pipeline (or sewage discharge inlet pipeline).

[0003] It is well known that the disadvantage of the vacuum sewage drainage system is that the vacuum toilet will generate huge drainage noise (about 90 decibels) during the drainage process. Other front-end collectors using vacuum sewage valves also have similar problems. To be precise, the vacuum toilet will generate two large noises during use, that is, when the vacuum sewage valve is opened, the vacuum toilet will generate a huge peak noise, and when the vacuum sewage valve is closed, the vacuum toilet will generate another huge peak noise. The fundamental reason for these peak noises is the real-time throttling effect of the internal opening and closing of the vacuum sewage valve, especially when it is about to open (the vacuum sewage valve is gradually opened) and when it is about to close (the vacuum sewage valve is gradually closed).

[0004] Over the past 30 years, researchers, mainly in Europe and the United States, have tried some methods and technologies to reduce the sewage noise generated by vacuum toilets and other related products in vacuum collection systems; although the domestic accumulation of related technologies has been relatively short, certain technological breakthroughs have been achieved.

[0005] The known technical solutions (see 1996-US5515554, 1994-US5317763, etc.) are to use an airtight toilet seat or a toilet seat with good noise absorption, or to add a separate auxiliary air supply pipeline to the vacuum drain valve. Although the solution is relatively simple and low-cost, the noise reduction technology and method is limited in its effect on reducing noise, reducing only about 1-3 decibels; in the prior art, in order to reduce noise, the researchers can significantly reduce the noise limit by reducing the on-off time of the vacuum drain valve. The specific feature of the technical solution is that the opening time of the vacuum drain valve is controlled to be less than 0.75 seconds, and the closing time of the vacuum drain valve is controlled to be less than 0.75 seconds. At the same time, an operating or control device is also proposed to meet the above basic operating speed requirements; the structure of the device includes three operating valves, which are controlled by a cam device driven by a piston / cylinder device; wherein, under the triggering action of a starting device, the first operating valve connects the pipeline connected to the vacuum source to the cylinder body chamber in the piston / cylinder device through the corresponding supply chamber, pipeline and storage chamber; the second operating valve connects the storage chamber with the drive unit through the corresponding pipeline to drive the vacuum drain valve; the third operating valve is used for vacuum toilet flushing pipeline control.

[0006] The known technical solutions (refer to 2000-US6128789A, 2002-EP0778432B1) use an airtight toilet seat or a toilet seat with good noise absorption, and also use a vacuum drain valve with active ventilation function. At the same time, the inventors have also effectively used the known technical experience, that is, by reducing the on-off time of the vacuum drain valve, the noise limit value can be significantly reduced. The specific feature of this technical solution is that the opening time of the vacuum drain valve is controlled to be less than 0.25 seconds, and the closing time of the vacuum drain valve is controlled to be less than 0.40 seconds. Although the solution is relatively simple and low in cost, the noise reduction technology and method are quite effective in reducing noise, reducing it by about 15 decibels; at the same time, an operating or control device is also proposed to meet the above-mentioned basic operating speed requirements; the structure of the device also includes three operating valves, and the three operating valves are also controlled by a cam device driven by a piston / cylinder device, which is similar to the previous technical solution.

[0007] Similar patents include:

[0008] Patent number US4928326 adds an integrated air supplement component near the flushing component of the vacuum toilet body to seal the toilet cover.

[0009] Patent number EP0436357 B1 adds a split air supply component near the flushing component to seal the toilet cover.

[0010] Patent number EP0778432 B1 opens a vent near the flushing assembly to replenish air from the bottom of the toilet body and seal the toilet lid.

[0011] Patent number WO012459A1 is an actively ventilated vacuum toilet and its control system. A vent is opened near the flushing component, and the air valve controls the automatic air replenishment to seal the toilet lid.

[0012] In summary, the above noise reduction technical scheme is mainly aimed at reducing noise in the following three aspects: first, while using a sealed toilet cover on the vacuum toilet body, a vent is introduced from the equipment chamber on the rear side of the toilet body for ventilation; second, a vacuum sewage valve with ventilation or air replenishment function is used, and the on-off (switch) speed is increased to 0.25 seconds and 0.4 seconds respectively; third, the internal air replenishment of the vacuum toilet body is ventilated through the bottom or rear lower opening of the toilet body; the air flow direction is from the bottom of the toilet to the top into the rear wall of the toilet body; part of the air enters the toilet body, and then is discharged from the vacuum sewage pipeline into the vacuum sewage pipeline; the other part of the air enters the air replenishment port of the vacuum sewage valve, and then is discharged from the vacuum sewage pipeline into the vacuum sewage pipeline.

[0013] Therefore, in addition to the core function of noise reduction, the detoxification function places higher demands on the use of toilets in military and civilian bathrooms; it requires the ability to efficiently discharge toxic gases released by patients near the toilet and residual in the air, such as toxic gases released by patients coughing and vomiting in the bathroom.

[0014] It is worth noting that the sound insulation and noise reduction method of the traditional vacuum toilet is achieved on the basis of two measures: delayed flushing and timely leaving the bathroom and closing the bathroom door. The solution or operation process of the traditional vacuum toilet noise reduction problem is as follows: after the person has finished defecating and using the toilet, he stands up, then turns around (when the button is on the back cover or side of the toilet body) and presses it or presses it sideways (when the toilet button is installed on the side wall of the human body), and then immediately leaves the bathroom and closes the door after pressing it; because the button has a delayed flushing function, the user is affected by the noise and leaves the bathroom and the flushing noise is minimized under the sound insulation effect of closing the bathroom door. This process is basically no problem when the noise cannot be effectively suppressed; it is worth noting that patients sometimes discharge some feces that release odor during the toilet process. In the above process, after the person stands up, the odor remaining in the toilet body will be diffused to other locations in the bathroom around the toilet under the action of the airflow generated when the human body changes from sitting to standing, causing the entire bathroom to stink. In general, it can be solved by opening windows for ventilation or turning on exhaust fans. This solution is not conducive to the use of hospital facilities with highly contagious virus patients; and the known technical solutions (refer to 2000-US 6128789A, 2002-EP 0778432B1, etc.) are that air enters the bottom of the toilet and then enters the toilet body and the vacuum drain valve respectively. A major disadvantage of this technical solution is that it is not conducive to timely removal of the odor released by human defecation.

[0015] However, under normal circumstances, residents may encounter other problems during use; for example, when owners smoke in the bathroom, especially when pregnant, the smell of smoke cannot be everywhere in the bathroom. Opening windows for ventilation will affect the diffusion effect due to windless weather, while the use of exhaust fans will increase energy consumption and noise, which is inconsistent with the theme of noise reduction. Other situations include the problem of dealing with the smell released by vomiting on the toilet due to excessive drinking.

[0016] Therefore, in summary, how to solve the three problems of deodorization, noise reduction and detoxification in traditional vacuum toilets is an urgent problem to be solved. Therefore, the present invention has developed a vacuum toilet with odor extraction, detoxification and noise reduction functions to solve the problems existing in the prior art. After searching, no technical solutions identical or similar to the present invention were found. Summary of the invention

[0092] More specifically, the detailed structure and specific working principle of the toilet body 1, the air-controlled water valve 2, the vacuum drain valve 3, the automatic controller 4, the manual controller 5, the inching controller 6 and the air-controlled button 7 are as follows:

[0093] First, the specific structure and working principle of the toilet body 1 are as follows:

[0094] like Figure 7 As shown, the toilet body 1 is generally used for wall installation, and a toilet cavity 11 is arranged inside. The toilet cavity 11 is a hollow structure with an upper end opening, and a reversible toilet cover is arranged at the upper end. A water inlet pipeline 12 and an odor extraction pipeline 13 are arranged around the upper end of the inner wall of the toilet cavity 11, and an air supply port 14 connected to the odor extraction pipeline 13 is arranged on the side wall. The lower end is connected to the sewage pipe 10; the water inlet pipeline 12 is connected to the water inlet pipe 8 The odor extraction pipeline 13 is connected to the exhaust pipe 9, and the air supply port 14 is arranged on the outer wall of the middle part of the front end of the toilet body 1. The air supply port 14 is plugged into and matched with an air supply guide 15 that can be pushed and pulled along the air supply port 14, and a connecting hose 16 is arranged between the inner end of the air supply guide 15 and the front end of the odor extraction pipeline 13; the space at the rear end of the toilet cavity 11 is used to place and install the air-controlled water valve 2, the vacuum sewage valve 3, the automatic controller 4, the manual controller 5 and the inching controller 6, so that the overall structure adopts the rear sewage discharge method for sewage discharge, and no water tank is set.

[0095] Regarding the active noise reduction of the toilet body 1, an air supply port 14 is set at the front end of the toilet body 1 for air supply, and at the same time, the toxic air at the front end of the toilet body 1 close to the user's stepping area is emptied into the toilet body 1 with maximum efficiency, and the noise reduction function is realized by setting the odor extraction pipeline 13 and the air supply port 14; Regarding the deodorization of the toilet body 1, the odor released by the user's excrement has two ways to be discharged, which can be discharged along the sewage pipe 10 with the excrement, and can also be discharged along the odor extraction pipeline 13, thereby achieving efficient removal of odor; Regarding the detoxification function of the toilet body 1, it is mainly that regardless of whether a vacuum toilet is used, as long as the toilet lid is opened and the channel where the odor extraction pipeline 13 is located is opened, the virus-carrying gas or smoke produced by smoking in the space near the toilet body 1 will be discharged through the odor extraction pipeline 13, thereby effectively realizing the detoxification function.

[0096] Second, the detailed structure and specific working principle of the air-controlled water valve 2 are as follows:

[0097] like Figure 8 , Fig. 9As shown, the air-controlled water valve 2 is provided with a water valve chamber 24 connected with the water inlet 21, the water outlet 22 and the first control interface A23, and the first valve core component 28 is provided in the water valve chamber 24. The water valve chamber 24 includes a first valve stem 281 for connecting and disconnecting the water inlet 21 and the water outlet 22 through axial movement, a first corrugated diaphragm 282 fixedly connected to the first valve stem 281, and a first reset spring 283 for resetting the first valve stem 281; the first corrugated diaphragm 282 is connected to the first control interface A23 at the top, and is connected to the water inlet 21 and the water outlet 22 at the bottom; the upper end of the water valve chamber 24 is provided with an upper inner hole 25 for the first valve stem 281 to be plugged in and move, and the lower end is provided with a lower inner hole 26 for the first valve stem 281 to move downward and be blocked, and the side is provided with a side flow channel 27 connected to both the upper inner hole 25 and the lower inner hole 26, and the lower inner hole 26 is connected to the water inlet 21; the cross-sectional area of ​​the upper end face and the lower end face of the first valve stem 281 is the same.

[0098] The working principle of the air-controlled water valve 2 is as follows:

[0099] In the non-working state, air is introduced into the first control interface A23, and the water pressure on the upper end face of the first valve stem 281 is realized through the water inlet 21, the side flow channel 27 and the upper inner hole 25, and the water pressure on the lower end face of the first valve stem 281 is realized through the water inlet 21 and the lower inner hole 26. Since the cross-sectional areas of the upper end face and the lower end face of the first valve stem 281 are the same, the pressures they are subjected to are consistent, so the total water pressures on the first valve core assembly 28 offset each other, so the closing of the first valve core assembly 28 is only affected by the elastic force of the first return spring 283. Through the action of the first return spring 283, the lower end portion of the first valve stem 281 is in the lower inner hole 26, thereby blocking the connection between the water inlet 21 and the water outlet 22. At this time, the air-controlled water valve 2 is in a water-free state.

[0100] In the working state, a vacuum is formed at the first control interface A23, and there is a pressure difference between the upper and lower ends of the first corrugated diaphragm 282. The pressure difference overcomes the compression force of the first return spring 283 to move the first valve stem 281 upward, and the lower end of the first valve stem 281 is separated from the lower inner hole 26, thereby connecting the water inlet 21 and the water outlet 22. At this time, the air-controlled water valve 2 is in a water-passing state.

[0101] Third, the detailed structure and specific working principle of the vacuum drain valve 3 are as follows:

[0102] like Fig.10 , Fig.11As shown, a drain valve chamber 36 is provided inside the vacuum drain valve 3, a communication channel 37 is formed between the sewage inlet 31 and the drain outlet 32, a second valve core assembly 38 is provided in the drain valve chamber 36, and extends into the communication channel 37, and its structure includes a second valve stem 381 for realizing the opening and closing of the communication channel 37 through axial movement, a second sealing guide plate 382 fixedly connected to the second valve stem 381, and a second reset spring 383 for realizing the reset of the second valve stem 381; the second sealing guide plate 382 is connected to the second control interface A35 at the top, and is connected to the air interface A34 at the bottom; as shown Fig.12 , Fig.13 As shown, the inner side of the second valve stem 381 is also provided with a first air pumping channel 311 running through it from top to bottom, and a one-way valve 314 arranged inside the first air pumping channel 311 for controlling the opening and closing of the first air pumping channel 311; the upper and lower ends of the first air pumping channel 311 are respectively provided with an upper air replenishing hole 312 and a lower air replenishing hole 313 which are connected to the air pumping interface 310 when the second valve core assembly 38 is opened and closed, and the air pumping interface 310 is arranged on the side of the second valve stem 381 that is biased towards the vacuum interface A33.

[0103] like Fig.14 , Fig.15As shown, a plug 384 is provided on one side of the second valve stem 381 that is biased toward the communicating flow channel 37. An inner valve core assembly 39 for sealing the second valve core assembly 38 and the inner wall of the communicating flow channel 37 is provided between the second valve stem 381 and the plug 384. The inner valve core assembly 39 includes an inner valve stem 391, a pair of sliders 392, and a special-shaped rubber sealing ring 393 that are arranged in sequence from top to bottom. The inner valve stem 391 divides the interior of the second valve stem 381 into an upper inner chamber 394 and a lower inner chamber 395. 95, the second valve stem 381 is provided with a negative pressure pipeline 396 extending to the side wall and communicating with the upper inner chamber 394, and a vacuum pipeline 397 communicating with the lower inner chamber 395; the negative pressure pipeline 396 is connected to one side of the sewage inlet 31, and the vacuum pipeline 397 is connected to one side of the sewage outlet 32, and the lifting and lowering movement of the inner valve stem 391 is realized by the change of the pressure difference; the special-shaped rubber sealing ring 393 is nested on the outer wall of the lower end of the second valve stem 381, and is connected to the inner valve stem 391 through the inner valve stem 391 The plug 384 is pushed by a pair of sliders 392 to achieve sealing contact with the inner wall of the connecting flow channel 37; the lower end of the plug 384 is a hemispherical structure, and the middle part of the upper end face is provided with a pair of wedge-shaped platforms in an eight-shaped shape, and the outer wall is provided with an annular groove along the vertical circumferential direction; a pair of sliders 392 are contacted and arranged on the wedge-shaped platform, and the special-shaped rubber sealing ring 393 is nested in a U shape in the annular groove, and the two ends extend upward and make the pair of sliders 392 contact with the inner wall of the end of the special-shaped rubber sealing ring 393; the inner valve stem 391 is arranged above the pair of sliders 392, and the lower end is in contact with the end of the slider 392, and the pair of sliders 392 are moved along the wedge-shaped platform through the lifting movement, thereby changing the end opening size of the U-shaped structure of the special-shaped rubber sealing ring 393.

[0104] The specific working principle of the vacuum drain valve 3 is as follows:

[0105] The working premise of the vacuum drain valve 3 is that one end of the drain port 32 is connected to a vacuum source in the downstream pipeline, so that the vacuum interface A33 is always kept in a vacuum state.

[0106] In the non-working state, air is introduced into the second control interface A35, and the air pressure at the upper and lower ends of the second sealing guide plate 382 is the same. The second valve core assembly 38 is moved downward by the second return spring 383. At this time, the lower end of the second valve stem 381 divides the interior of the communication flow channel 37 into two parts, thereby causing the second valve stem 381 to deviate toward the sewage outlet 32. The pressure at one end decreases, while the pressure at the end biased toward the sewage inlet 31 increases. Since the vacuum line 397 is located on the side biased toward the sewage outlet 32, the negative pressure line 396 is located on the side biased toward the sewage inlet 31, and the vacuum line 397 is connected to the lower inner chamber 395, and the negative pressure line 396 is connected to the upper inner chamber 394, the pressure in the lower inner chamber 395 decreases, and the pressure in the upper inner chamber 394 increases. The inner valve stem 391 descends, pushing a pair of sliders 392 to move to both sides along the wedge-shaped platform, and then pushing the special-shaped rubber sealing ring 393, and finally achieving the sealing at the intersection line of the connecting flow channel 37 and the lower end of the second valve stem 381, and achieving the closure and effective sealing of the connecting flow channel 37; at the same time, as Fig.12 As shown, the upper air supply hole 312 is aligned with the air extraction interface 310, and the one-way valve 314 is in a normally open state. Since the first air extraction flow channel 311 is connected to the vacuum interface A33, the vacuum state can also be maintained at the air extraction interface 310.

[0107] Under the working state, a vacuum is formed in the second control interface A35, and the air pressure above the second sealing guide plate 382 is less than the air pressure below. The second valve stem 381 overcomes the action of the second compression spring and rises. At this time, the sewage inlet 31 is connected to the sewage outlet 32 ​​for discharging sewage, and the air pressure in the negative pressure pipeline 396 and the vacuum pipeline 397 is the same, so the pressure difference between the upper inner chamber 394 and the lower inner chamber 395 disappears, the inner valve stem 3911 moves upward, a pair of sliders 392 retreat, and the special-shaped rubber sealing ring 393 is reset to reduce the clamping force; at the same time, the lower air replenishment hole 313 is aligned with the air extraction interface 310. Since the first air extraction flow channel 311 is connected to the vacuum interface A33, the vacuum state can still be maintained at the air extraction interface 310.

[0108] Fourthly, the detailed structure and specific working principle of the automatic controller 4 are as follows:

[0109] like Fig.16 , Fig.17 , Fig.18As shown, the automatic controller 4 is internally provided with an automatic control chamber connected with the input interface A41, the output interface A42, the air interface B43 and the third control interface A44; the third valve core assembly 45 is arranged in the automatic control chamber, including a third valve stem 451 for realizing the connection and disconnection of the input interface A41 and the output interface A42 through axial movement, a third corrugated diaphragm 452 fixedly connected to the third valve stem 451, and a third reset spring 453 for realizing the reset of the third valve stem 451; the third corrugated diaphragm 452 is connected with the third control interface A44 at the top and connected with the air interface B43 at the bottom; a concave cavity 46 is arranged at the side wall of the third valve stem 451; in the non-working state, the concave cavity 46 is staggered with the inner side ends of the input interface A41 and the output interface A42; in the working state, the concave cavity 46 is aligned with the inner side ends of the input interface A41 and the output interface A42, thereby realizing the connection between the input interface A41 and the output interface A42.

[0110] The working principle of the automatic controller 4 is as follows:

[0111] In non-working state, such as Fig.18 As shown, air is introduced into the third control interface A44, and air is also introduced into the air interface B43, so that the pressure above and below the third corrugated diaphragm 452 is the same, and the concave cavity 46 at the side wall of the third valve stem 451 is not aligned with the inner ends of the input interface A41 and the output interface A42. At this time, the input interface A41 and the output interface A42 are in a disconnected state.

[0112] In the working state, a vacuum is formed at the third control interface A44, and air is introduced into the air interface B43. At this time, the pressure above the third corrugated diaphragm 452 is less than the pressure below, and the third valve stem 451 moves upward, so that the concave cavity 46 is aligned with the inner ends of the input interface A41 and the output interface A42. At this time, the input interface A41 and the output interface A42 are in a connected state.

[0113] It should be noted that other input and output interfaces are also illustrated in the figure, which are not needed in this embodiment and can be blocked.

[0114] Fifth, the detailed structure and specific working principle of the manual controller 5 are as follows:

[0115] like Fig.19 , Fig. 20As shown, the manual controller 5 is internally provided with a manual control chamber connected with the vacuum interface B51, the air interface C52, the first control interface B53, the second control interface B54 and the third control interface B55, and the fourth valve core assembly 56 is arranged in the manual control chamber, including a fourth valve stem 561 which realizes intermittent connection of the first control interface B53, the second control interface B54 and the third control interface B55 with the vacuum interface B51 and the air interface C52 through axial movement, a fourth corrugated diaphragm 562 fixedly connected to the fourth valve stem 561, and a fourth reset spring 563 for resetting the fourth valve stem 561; the manual button 57 is arranged above the manual controller 5, extending to the outside of the toilet body 1 for easy pressing at the top, and extending into the manual control chamber at the bottom, and abutting against the upper end of the fourth valve stem 561 to realize the pressing movement of the fourth valve stem 561.

[0116] Among them, the vacuum interface B51, the air interface C52, the first control interface B53, the second control interface B54 and the third control interface B55 are all arranged on the lower end surface of the manual controller 5; the pipeline connected to the vacuum interface B51 is bent at 90°, and the inner end is connected to the manual control chamber, and the pipeline connected to the air interface C52 is bent at 90°, and the inner end is connected to the manual control chamber; Fig.21 , Fig. 22 As shown, the first control interface B53, the second control interface B54 and the third control interface B55 all extend upward, and have an annular cavity 58 at the upper end. The pipeline at the upper end of the annular cavity 58 is bent at 90°, and the inner end (i.e., point M in the figure) is connected to the manual control chamber, so that the first control interface B53, the second control interface B54 and the third control interface B55 can simultaneously allow air to pass through or simultaneously form a vacuum.

[0117] The fourth valve stem 561 has a T-shaped ventilation cavity at its lower end. In a non-working state, the ventilation cavity is connected to the air interface C52 and point M. In a working state, the ventilation cavity is connected to the vacuum interface B51 and point M.

[0118] The specific working principle of the manual controller 5 is as follows:

[0119] like Fig.23As shown, in the non-working state, the manual button 57 is in a non-pressed state. At this time, the fourth valve core assembly 56 is in a reset state due to the action of the fourth reset spring 563, and the air interface C52 is connected to point M. Since point M is connected to the first control interface B53, the second control interface B54 and the third control interface B55 through the annular cavity 58, air is passed into the first control interface B53, the second control interface B54 and the third control interface B55. At this time, air is passed into the first control interface A23, the second control interface A35 and the third control interface A44 connected thereto, and the air-controlled water valve 2, the vacuum drain valve 3 and the automatic controller 4 are all in a non-working state.

[0120] like Fig.24 As shown, in the working state, the manual button 57 is in a pressed state, at this time the fourth valve core assembly 56 is pressed down, the vacuum interface B51 is connected with point M, so that a vacuum is formed in the first control interface B53, the second control interface B54 and the third control interface B55, and at this time a vacuum is also formed in the first control interface A23, the second control interface A35 and the third control interface A44 connected thereto, and the air-controlled water valve 2, the vacuum drain valve 3 and the automatic controller 4 are all in working state.

[0121] Sixth, the detailed structure and specific working principle of the jog controller 6 are as follows:

[0122] like Fig.25 , Fig.26 , Fig. 27 As shown, the inching controller 6 is provided with an inching control chamber 60 connected to the air interface D61, the fourth control interface A62, the input interface B63 and the output interface B64, and an air flow channel 605 and a second air extraction channel 606 are provided on the inner side; Fig.28 As shown, the inching control chamber 60 includes a first cavity 601, a second cavity 602, a third cavity 603 and a fourth cavity 604 arranged in sequence from top to bottom; the fifth valve core assembly 65 is arranged in the inching control chamber 60, as shown in FIG. Fig.29As shown, it includes an upper valve core assembly 66, a middle valve core assembly 67 and a lower valve core assembly 68 which are coaxially arranged from top to bottom; the upper valve core assembly 66 is arranged in the first cavity 601, including an upper valve stem 661, an upper sealing guide plate 662 which is fixedly arranged in an integral structure with the upper valve stem 661, and an upper return spring 663 for realizing the return of the upper valve stem 661; the middle valve core assembly 67 is arranged through the first cavity 601 and the second cavity 602, including a middle valve stem 671, and a middle return spring 672 for realizing the return of the middle valve stem 671, and a notch A673 which connects the first cavity 601 and the second cavity 602 in a non-reset state is arranged on the side wall of the middle valve stem 671; the lower valve core assembly 68 is arranged through the second cavity 602 and the third cavity 603, including a lower valve stem 68 ...81, and an upper return spring 663 for realizing the return of the upper valve stem A fixedly connected lower corrugated diaphragm 682 and a lower return spring 683 for returning the lower valve stem 681, a notch B684 is provided on the side wall of the lower valve stem 681 for connecting the second cavity 602 and the third cavity 603 in a non-resetting state; the air flow channel 605 is connected with the fourth cavity 604 and the upper and lower parts of the upper sealing guide plate 662, the upper end of the second air extraction channel 606 is connected with the lower part of the lower corrugated diaphragm 682, and the lower end is connected with the output interface B64, and the input interface B63 is connected with the third cavity 603, so that when the lower valve stem 681 is in a non-resetting state, the input interface B63, the third cavity 603, the notch B684, the second cavity 602, the second air extraction channel 606 and the output interface B64 are connected in sequence.

[0123] The working principle of the inching controller 6 is as follows:

[0124] like Fig. 27 As shown, in the non-working state, the air pressure at the fourth control interface A62 is normal (mainly because the air control button 7 connected thereto is in a non-pressed state), and the upper valve core assembly 66, the middle valve core assembly 67 and the lower valve core assembly 68 are in a reset state respectively under the action of the upper return spring 663, the middle return spring 672 and the lower return spring 683, and the lower valve stem 681 disconnects the connection between the second cavity 602 and the third cavity 603. Since the input interface B63 is connected to the third cavity 603, the output interface B64 is connected to the lower end of the second cavity 602 through the second air exhaust channel 606, which ultimately causes the input interface B63 and the output interface B64 to be in a disconnected state.

[0125] like Fig.30As shown, in the working state, the pressure at the fourth control interface A62 increases (mainly because the air control button 7 connected thereto is in a pressed state), and the pressure overcomes the spring forces of the upper return spring 663, the middle return spring 672 and the lower return spring 683 in turn, thereby realizing the downward movement of the upper valve stem 661, the middle valve stem 671 and the lower valve stem 681, so that due to the action of the notch B684, the lower end of the second cavity 602 and the third cavity 603 are connected. Since the input interface B63 is connected to the third cavity 603, the output interface B64 is connected to the lower end of the second cavity 602 through the second air extraction channel 606, and finally the input interface B63 and the output interface B64 are in a connected state, and the connecting path passes through the input interface B63, the third cavity 603, the notch B684, the second cavity 602, the second air extraction channel 606 and the output interface B64 in turn, as shown by the dotted line in the figure.

[0126] It should be noted that there are two input interfaces in the figure, and only one of them needs to be used in this embodiment. When the other one is not needed, it can be blocked.

[0127] Seventh, the detailed structure and specific working principle of the gas control button 7 are as follows:

[0128] like Fig.31 As shown, the air-controlled button 7 can be used to be installed on the side wall of the rear end of the toilet body 1 or on a wall near the installation position of the toilet body 1, including a base 72, a shell 73, a button cap 74 nested inside the shell 73, and a fifth reset spring 75 for realizing the pressing and resetting of the button cap 74; the base 72, the shell 73 and the button cap 74 together form a button cavity 76 that can change the space and internal air pressure by pressing the button cap 74, and the button cavity 76 is connected to the fourth control interface B71, and the fourth control interface B71 is used to communicate with the fourth control interface A62.

[0129] The working principle of the gas control button 7 is as follows:

[0130] In the non-working state, the button cap 74 is in a non-pressed state, the pressure in the button cavity 76 and the fourth control interface B71 is normal, and the pressure at the fourth control interface A62 connected thereto does not change, so that the inching controller 6 does not operate.

[0131] In the working state, the button cap 74 is in a pressed state, the volume of the button cavity 76 becomes smaller, and the internal air pressure increases, thereby increasing the pressure at the fourth control interface B71 and the fourth control interface A62, and triggering the inching controller 6 to start working.

[0132] Based on the working principles of the above structures, the overall working principle of the vacuum toilet with odor extraction, detoxification and noise reduction functions of the present invention is as follows:

[0133] (1) Regarding active odor extraction, it is mainly because the production of excrement will release odor; press the manual button 57, and the first control interface B53, the second control interface B54 and the third control interface B55 are all connected to the vacuum interface B51 to form a vacuum, so the first control interface A23, the second control interface A35 and the third control interface A44 are all vacuum, thereby triggering the air-controlled water valve 2, the vacuum sewage valve 3 and the automatic controller 4 to start working; Fig.32 As shown by the solid line with arrows, the air-controlled water valve 2 is used to flush water into the toilet chamber 11, and the vacuum sewage valve 3 is used to flush away the excrement. Fig.32 As shown by the dotted line in FIG, the automatic controller 4 is used to extract the generated odor and discharge it along the vacuum drain valve 3.

[0134] (2) Regarding active detoxification, whether or not a vacuum toilet is used, when virus-carrying gas or smoke from smoking is generated in the space near the toilet body 1, the gas control button 7 is pressed, and only the inching controller 6 works, and the input interface B63 and the output interface B64 are connected, such as Fig.33 As shown by the dotted line in the figure, the inching controller 6 is used to extract the generated odor and discharge it along the vacuum drain valve 3, wherein the air extraction interface 310 is in a vacuum state regardless of whether the vacuum drain valve 3 is in an open or closed state.

[0135] (3) Regarding active noise reduction, an air supply port 14 is set at the front end of the toilet body 1 to supply air, and at the same time, the toxic air at the front end of the toilet body 1 close to the user's stepping area is emptied into the toilet body 1 with maximum efficiency. The noise reduction function is achieved through the setting of the odor extraction pipeline 13 and the air supply port 14, and the cooperation of the vacuum drain valve 3 with noise reduction function. The noise reduction of the vacuum drain valve 3 is due to the setting of the air extraction interface 310, which can achieve the air supply and noise reduction function.

[0136] In a vacuum toilet with odor extraction, detoxification and noise reduction functions of the present invention, a manual controller 5 can simultaneously control the air-controlled water valve 2, the vacuum sewage valve 3 and the automatic controller 4 to work, thereby realizing the automatic control process through the manual button 57, and the air-controlled button 7 can independently control the moment controller 6 to work, thereby realizing the moment control process through the air-controlled button 7, and finally enabling the vacuum toilet to realize the dual mode of moment control and automatic control.
