Description

Technical Field

[0001] The present invention relates to the technical field of intelligent toilet deodorization function detection, and in particular to a sampling device for intelligent toilet deodorization function detection. Background Art

[0002] Deodorization is the most basic function of smart toilets. Currently, deodorization technologies include activated carbon deodorization technology, diatom pure deodorization technology, air negative pressure deodorization technology, etc. Various deodorization technologies vary in quality, and the actual deodorization effects are mixed. Therefore, when conducting a systematic study on various types of smart toilets, it is necessary to test the deodorization function of smart toilets. The existing method of testing the deodorization function of smart toilets is usually to place an odor source (methane or hydrogen sulfide, etc.) in the smart toilet, then turn on the deodorization function of the smart toilet, and use the existing gas collection device to indirectly collect the odor near the smart toilet in batches, and measure the rate at which the odor content in the air near the smart toilet gradually decreases over time. , to judge the quality of the deodorization function of the smart toilet, the existing gas collection device usually directly passes air into the hydrogen sulfide absorption liquid when collecting hydrogen sulfide. In the process of air floating up in the absorption liquid, large bubbles are formed, and the hydrogen sulfide in the bubbles is gradually absorbed by the absorption liquid. Then the staff uses the existing device to detect the amount of hydrogen sulfide in the absorption liquid to judge the deodorization efficiency of the deodorization function of the smart toilet. After the existing gas collection device passes the gas into the absorption liquid, the gas forms large bubbles in the absorption liquid and floats upward. Because part of the gas in the large bubbles is not in direct contact with the absorption liquid, the hydrogen sulfide in the bubbles is not completely absorbed and is discharged to the outside, resulting in the inaccurate amount of hydrogen sulfide absorbed by the absorption liquid, resulting in deviations in the measurement results.

DETAILED DESCRIPTION

[0028] The technical solution is further described below in conjunction with specific embodiments. It should be noted that the words indicating directions such as upper and lower mentioned in this article are only for the position of the structure shown in the corresponding drawings. The serial numbers assigned to the components in this article, such as first, second, etc., are only used to distinguish the objects described and do not have any order or technical meaning.

[0029] Hydrogen sulfide has the smell of rotten eggs and is the main odor element in the human defecation process. Existing gas collection devices usually determine the hydrogen sulfide content in the gas by drawing hydrogen sulfide into the corresponding absorption liquid for absorption. During the deodorization function test of the smart toilet, because the gas is passed into the existing gas collection device, large bubbles are usually formed and float upward, making it difficult for some hydrogen sulfide in the large bubbles to contact with the absorption liquid, and then making it difficult for the absorption liquid to completely absorb the hydrogen sulfide in the bubbles, affecting the accuracy of the test results.

[0030] Therefore, a sampling device for detecting the deodorization function of an intelligent toilet is proposed. Figure 1-Figure 5, including: a mounting frame 1, on which a rotating frame 101 is installed, on which a plurality of collecting barrels 9 are installed, the mounting frame 1 is fixedly connected to a fixed column 2, on which a transmission device 3 is installed, on which a fixed block 4 is fixedly connected to the transmission device 3, on which a fixed frame 5 is fixedly connected; a fixed shell 6, fixedly connected to the fixed frame 5, fixedly connected to and communicated with a ventilation hose 61, which is communicated with a small air pump, and an air storage cover 7 is fixedly connected to the upper side of the fixed shell 6 through a support rod, and ventilation holes 71 distributed at intervals are arranged on the upper side of the air storage cover 7; an air guide 8, which is connected and arranged on the fixed shell 6, and an electric clamp 102 is installed on the fixed frame 5, and the electric clamp 102 is used to clamp the collecting barrel 9, and the collecting barrel 9 is sealed with the fixed shell 6, and the fixed shell 6 is located on the upper part of the collecting barrel 9.

[0031] In the above scheme, the rotating frame 101 is an electric control unit, and several collecting cylinders 9 are respectively used to store the gas collected at different times to obtain the deodorization efficiency curve of the deodorization function of the intelligent toilet. The rotating frame 101 is electrically connected to the remote control terminal, and the mounting frame 1 is fixedly connected with a first seal 103, and the first seal 103 is sealed with the collecting cylinder 9 on the rotating frame 101. The transmission device 3 is fixedly connected with a second seal 104, and the second seal 104 is sealed with the collecting cylinder 9 on the rotating frame 101 that is not sealed with the first seal 103. The first seal 103 and the second seal 104 are both used to prevent the hydrogen sulfide collected in the collecting cylinder 9 from volatilizing outwards. The collecting cylinder 9 is made of an opaque material to prevent the decomposition of hydrogen sulfide due to light. A solution for collecting hydrogen sulfide is contained in the collecting cylinder 9, and an exhaust valve that exhausts outwards and prevents the solution from flowing outwards is provided at the bottom of the collecting cylinder 9. Figure 3 The collecting tube 9 is placed upside down; the transmission device 3 is a combined electric control component, including a plurality of electric push rods and electric shafts, etc. The transmission device 3 is used to drive the fixed block 4, the fixed frame 5 and the electric clamp 102 to rotate with the fixed column 2 as the axis, or drive the fixed frame 5 and the electric clamp 102 to shift up and down with the fixed block 4 as the center, so as to move the fixed shell 6 to the lower side of the collecting tube 9, and the electric clamp 102 is used to clamp the adjacent collecting tube 9 on the rotating frame 101, and at the same time drive the collecting tube 9 to move up and down, so that the fixed shell 6 completes the upper end of the collecting tube 9 The opening is blocked, the transmission device 3 and the electric clamp 102 are electrically connected to the remote control terminal, the gas storage cover 7 is composed of a circular cover and a straight cylinder, the vent holes 71 are distributed on the circular cover, the vent holes 71 are used to separate the gas on the lower side into small bubbles and float upward, and the straight cylinder on the gas storage cover 7 is used to increase the total amount of gas stored in the gas storage cover 7; the ventilation hose 61 is connected to a small air pump for extracting the gas around the smart toilet through the ventilation hose 61, the small air pump is electrically connected to the remote control terminal, and a one-way valve is installed in the ventilation hose 61, and the one-way valve in the ventilation hose 61 only allows adjacent fluids to flow in Figure 3In this state, the air flows from bottom to top, the diameter of the vent hole 71 is small and the distance between two adjacent vent holes 71 is far, which is used to ensure that after the gas emerges upward from the vent hole 71, a bubble with a smaller diameter is formed, and the gas discharged from the two adjacent vent holes 71 will not contact each other when discharged, reducing the probability of two small bubbles merging to form a larger bubble. At this time, if the efficiency of the small air pump exhausting the air into the air storage cover 7 through the hose 61, the fixed shell 6 and the air guide 8 is greater than the efficiency of the gas in the air storage cover 7 being discharged upward from the vent hole 71 under the action of its own buoyancy, the gas in the air storage cover 7 will gradually accumulate, otherwise the gas will not accumulate in the air storage cover 7. In order to collect more gas in a shorter time and ensure that the data sampled in this experiment can better express the total amount of odor contained in the gas at a certain time point, under the premise that the diameter of the vent hole 71 does not change, the efficiency of the small air pump in this scheme to absorb gas is greater than the efficiency of the gas in the air storage cover 7 being discharged through the vent hole 71.

[0032] The working process is as follows: before the staff starts to test the deodorization function of the smart toilet, they first control the transmission device 3 through the remote control terminal to drive the fixed block 4, the fixed frame 5 and the electric clamp 102 to rotate to one side of the rotating frame 101. At this time, the fixed frame 5 and the fixed shell 6 are both located on the upper side of the fixed block 4. The remote control terminal controls the electric clamp 102 to clamp the adjacent collecting cylinder 9. Then the remote control terminal controls the electric clamp 102 to drive the adjacent collecting cylinder 9 to move upward until the collecting cylinder 9 and the fixed shell 6 are sealed with each other. At this time, the air storage cover 7 is located in the collecting cylinder 9. The remote control terminal controls the transmission device 3 to drive the fixed frame 5 and the electric clamp 102 to rotate around the fixed block 4, so that the fixed shell 6 and the collecting cylinder 9 exchange positions with each other. The remote control terminal controls the transmission device 3 to drive the fixed shell 6 and the collecting cylinder 9 to rotate horizontally and move out of the rotating frame 101. At this time, the position status of the electric clamp 102, the first seal 103, the second seal 104 and the collecting cylinder 9 is as follows Figure 2 As shown, the staff then prepared to collect the odor emitted from the smart toilet.

[0033] After the staff put the odor source into the smart toilet according to the experimental process, the deodorization function of the smart toilet is started, and the small air pump is started through the remote control terminal at the same time. The small air pump collects the odor emitted from the smart toilet through the ventilation hose 61, and inputs the odor into the fixed shell 6. The odor flows into the collecting cylinder 9 through the air guide 8. After the bubbles enter the collecting cylinder 9, they are located on the lower side of the air storage cover 7. At this time, only some bubbles can directly float upward through the vent 71, and most of the bubbles are intercepted on the lower side of the air storage cover 7. While the bubbles float upward, the hydrogen sulfide and other gases therein gradually precipitate into the surrounding solution. Because the diameter of the bubbles discharged from the gas in the air storage cover 7 through the vent 71 is small, the efficiency of the solution in absorbing hydrogen sulfide is high. When the ventilation hose 61 collects a certain amount of gas, the staff moves the ventilation hose 61 to a place connected to the external gas (even if the ventilation hose 61 is stopped The odor emitted from the smart toilet is no longer inhaled, but begins to absorb fresh air from the outside to ensure that the residual odor in the ventilation hose 61 is completely discharged into the collecting tube 9). After a certain period of time, the lower side of the gas storage cover 7 is full of gas, and the staff turns off the small air pump through the remote control terminal. The liquid cannot flow downward through the one-way valve in the ventilation hose 61. The gas on the lower side of the gas storage cover 7 is gradually discharged upward under the action of its own buoyancy. When the gas in the gas storage cover 7 is completely discharged, the staff controls the transmission device 3 to move through the remote control terminal, and puts the collecting tube 9 back into the rotating frame 101 in the opposite way of the above operation. Then the remote control terminal controls the rotating frame 101 to rotate, so that this collecting tube 9 is sealed with the first sealing member 103, and the next collecting tube 9 is exposed at the same time. At this time, because the gas is not collected temporarily, the remote control terminal drives the transmission device 3 to drive the adjacent parts to move to Fig.10 In the state shown, the second sealing member 104 seals the adjacent collecting tube 9 to prevent the collecting tube 9 from being in an unsealed state and the solution therein from evaporating outwards.

[0034] After a certain period of time, the staff uses the next collection tube 9 to collect the odor emitted by the smart toilet again and repeats the above steps. After collecting multiple groups of gases continuously, the staff takes away the collection tube 9 and puts them into the detection device for detection in turn, and draws a curve of odor dissipation when the smart toilet is deodorized to evaluate the deodorization function of the smart toilet.

[0035] As an improvement to the above solution, refer to Figure 4 and Figure 5 The vent hole 71 is an inclined through hole, and the vertical plane where the axis of the vent hole 71 is located is parallel to the axis of the air storage cover 7.

[0036] In the above scheme, the vent holes 71 are made into inclined through holes so that the bubbles discharged from the vent holes 71 float in the extension direction of the vent holes 71. At the same time, the vertical plane where the axes of all the vent holes 71 are located is parallel to the axis of the gas storage cover 7, so that the extension lines of the axes of all the vent holes 71 in the horizontal direction form a plurality of concentric polygons. The bubbles sprayed from the gas storage cover 7 drive the surrounding solution to swirl around the axis of the gas storage cover 7, thereby promoting the contact efficiency between the bubbles and the solution, and thereby improving the efficiency of the solution absorbing the hydrogen sulfide in the bubbles.

[0037] As an improvement to the above solution, refer to Figure 5-Figure 7 , also includes: a closing mechanism, which is arranged on the upper part of the air guide 8 and is used to control the opening and closing of the upper port of the air guide 8. The closing mechanism includes: a fixed plate 10, which is fixed to the upper part of the air guide 8. The upper part of the air guide 8 is rotatably connected with a rotating plate 11. The rotating plate 11 and the fixed plate 10 are both provided with conducting holes. The adjacent conducting holes on the two are connected and matched with each other. The air guide 8 is slidably connected with the fixed shell 6, and the air guide 8 is in contact with the air storage cover 7; a sliding ring 12, which is slidably connected to the outer side of the air guide 8, and the sliding ring 12 is low Density material; a sliding rod 13, slidably connected to the air guide 8, the sliding rod 13 is slidably connected to a sliding rack 14, and a first elastic member is installed between the two, the rotating plate 11 is fixedly connected to a gear meshing with the sliding rack 14, the sliding ring 12 is fixedly connected to a first extrusion block 15 extruded and matched with the sliding rod 13, and the air storage cover 7 is fixedly connected to a second extrusion block 16 extruded and matched with the sliding rod 13; a driving assembly is arranged in the fixed shell 6, and is used to push the air guide 8 to move upward, and use the air guide 8 to quickly discharge the gas in the air storage cover 7.

[0038] In the above scheme, there is a certain damping between the rotating plate 11 and the air guide 8, which is used to delay the rotation of the rotating plate 11. The number and diameter of the conducting holes on the fixed plate 10 are the same as those on the rotating plate 11. When the conducting holes on the rotating plate 11 and the fixed plate 10 are connected, the gas in the air guide 8 is normally ejected upward. When the rotating plate 11 rotates, the conducting holes on the rotating plate 11 and the adjacent conducting holes on the fixed plate 10 are gradually staggered, and the upper part of the air guide 8 is blocked by the rotating plate 11 and the fixed plate 10, so that the gas can only be retained in the air guide 8, so as to avoid excessive gas storage in the gas storage cover 7, causing the gas to be discharged from the lower part of the gas storage cover 7. The sliding ring 12 is made of low-density material and will float upward under the influence of the surrounding solution, so that it is located on the upper part of the air guide 8. When the gas on the lower side of the gas storage cover 7 gradually increases, causing the liquid level of the solution to gradually move downward, the liquid level of the solution drives the sliding ring 12 to move downward together. A sealing ring is provided on the outer side of the air guide 8 for sealing the connection position between the air guide 8 and the gas storage cover 7 when the air guide 8 is in contact with the gas storage cover 7, so as to facilitate the air guide 8 to push the upper gas to be discharged to the upper side of the gas storage cover 7.

[0039] The working process is as follows: when the staff guides the air into the air storage cover 7 through the air guide 8, the gas in the air storage cover 7 gradually increases, causing the liquid level of the solution on the lower side of the air storage cover 7 to gradually decrease. When the liquid level of the solution on the lower side of the air storage cover 7 gradually decreases to the sliding ring 12, the liquid level drives the sliding ring 12 to move downward together. The sliding ring 12 squeezes the sliding rod 13 through the first squeezing block 15 to move horizontally. The sliding rod 13 pulls the sliding rack 14 through the first elastic member to gradually move. The sliding rack 14 drives the rotating plate 11 to rotate through the gear. At this time, because there is damping between the rotating plate 11 and the air guide 8, the rotating plate 11 rotates. The speed is slow, and the first elastic member stretches and accumulates force, so the conducting hole between the rotating plate 11 and the fixed plate 10 will not be suddenly blocked, causing the sliding ring 12 to stop moving downward. Instead, when the sliding rod 13 moves to the end of the stroke, the sliding ring 12 stops moving downward, and then the first elastic member pulls the sliding rack 14 to continue to slide under the action of its own elastic force, so that the conducting holes between the rotating plate 11 and the fixed plate 10 gradually block each other, and the gas injection amount is gradually reduced, avoiding the gas from gushing upward from the outside of the gas storage cover 7, and then avoiding the formation of large bubbles, which affects the efficiency of the absorption liquid in absorbing hydrogen sulfide in the gas.

[0040] When the conducting hole on the fixed plate 10 is blocked, the driving component drives the air guide 8 to move upward, and the air guide 8 moves and fits the inner wall of the gas storage cover 7, squeezing the gas in the gas storage cover 7 to be quickly discharged upward from the vent hole 71. On the one hand, by accelerating the speed of bubbles ejecting from the vent hole 71, the bubbles push the surrounding solution to move with stronger power, accelerate the flow speed of the solution in the collecting tube 9, and promote the solution to absorb the hydrogen sulfide in the bubbles. On the other hand, it assists the rapid discharge of the gas in the gas storage cover 7 to speed up the experimental efficiency. When the air guide 8 moves to the upper part of the gas storage cover 7, the second squeezing block 16 squeezes the sliding rod 13 to reset, so that the rotating plate 11 releases the blockage of the air guide 8. The sliding rod 13 is reset to control the rotating plate 11 to reconnect with the adjacent conducting hole on the fixed plate 10 through the sliding rack 14. At this time, the driving component drives the air guide 8 to move downward and reset (reset to Figure 5 When the air guide 8 is completely restored, the staff repeats the above steps until the staff stops collecting odor.

[0041] As an improvement to the above solution, refer to Figure 6 The upper surface of the air guide 8 is located on the upper side of the lower surface of the air storage cover 7.

[0042] In the above scheme, the upper surface of the air guide 8 is placed on the upper side of the lower surface of the air storage cover 7, and at the same time, the axis of the sliding rod 13 is ensured to be located on the upper side of the lower surface of the air storage cover 7, thereby ensuring that the gas ejected from the air guide 8 will not directly overflow from the lower surface of the air storage cover 7.

[0043] As an improvement to the above solution, refer to Figure 4 and Figure 5 The angle between the axis of the vent hole 71 and the horizontal plane is less than 30°, and the collecting tube 9 is fixedly connected with an air guide ring 91 for guiding the bubbles.

[0044] In the above scheme, by limiting the direction of the axis of the vent hole 71, the gas ejected from the vent hole 71 has the characteristic that the horizontal speed is greater than the vertical speed, thereby promoting the ability of the bubbles to drive the surrounding liquid to flow, and at the same time avoiding the bubble ejection speed being too fast, which causes the bubbles to float up quickly, resulting in the hydrogen sulfide in the bubbles not being completely absorbed. The air guide ring 91 is used to cooperate with the guidance of the vent hole 71 to guide the bubbles on the outside and in contact with the air guide ring 91 inward, promote the mixing of adjacent liquids, further hinder the bubbles from floating directly upward, and increase the efficiency of the hydrogen sulfide in the bubbles to be discharged outward.

[0045] As an improvement to the above solution, refer to Figure 4 and Figure 5 The air guide member 8 is slidably connected to the limiting member 17 , and a second elastic member is installed between the two, and the limiting member 17 is pressed and matched with the sliding rack 14 .

[0046] In the above scheme, the second elastic member is a spring, the limit member 17 has two symmetrically distributed inclined surfaces, the sliding rack 14 is fixedly connected with a triangular block, and the triangular block has two symmetrically distributed inclined surfaces. The limit member 17 and the triangles on the sliding rack 14 are squeezed and matched with each other through adjacent inclined surfaces. When the sliding rack 14 is driven by the first elastic member to move with the sliding rod 13, the limit member 17 hinders the movement of the sliding rack 14 by squeezing the sliding rack 14 until the elastic force of the first elastic member gradually increases, so that the sliding rack 14 gradually squeezes the limit member 17 to slide, and the second elastic member is compressed and stored. When the sliding rack 14 passes through the limit member 17, the limit member 17 squeezes the sliding rack 14 to move quickly under the action of the elastic force of the second elastic member, thereby prompting the sliding rack 14 to quickly drive the rotating plate 11 to rotate, so that the action of the rotating plate 11 blocking the upper part of the air guide member 8 is faster and more accurate, thereby improving the reliability of the device.

[0047] As an improvement to the above solution, refer to Figure 6 and Figure 8 The driving assembly includes: a piston plate 18, which is fixedly connected to the lower part of the air guide member 8. The piston plate 18 is slidably connected to the fixed shell 6, and a third elastic member is installed between the two. An air storage chamber is formed between the piston plate 18 and the fixed shell 6. The air storage chamber is located on the side of the piston plate 18 facing the ventilation hose 61. The air storage chamber is connected to the ventilation hose 61 and the air guide member 8. The piston plate 18 is fixedly connected with a sealing gasket 181; a limiting ball 19, which is slidably connected to the fixed shell 6, and a fourth elastic member is installed between the two. The limiting ball 19 is limitedly matched with the piston plate 18.

[0048] In the above scheme, Figure 8For example, the air storage chamber is located at the lower side of the piston plate 18, the third elastic member and the fourth elastic member are both springs, the sealing gasket 181 is made of a deformable material, and the piston plate 18 is initially in contact with the fixed shell 6 through the sealing gasket 181, and the limiting ball 19 limits the piston plate 18. Therefore, the gas pressure is not enough to push the piston plate 18 to move at this time, so the gas does not enter the air storage chamber between the piston plate 18 and the fixed shell 6, and directly enters the air guide member 8. When the rotating plate 11 does not block the air guide member 8, the limiting ball 19 limits the piston plate 18 under the drive of the third elastic member, and then limits the air guide member 8. When the rotating plate 11 blocks the air guide member 8 The gas entering the fixed shell 6 has nowhere to go, and thus squeezes the piston plate 18 to move upward. The piston plate 18 is forced to press the limiting ball 19 back into the fixed shell 6, thereby releasing the limiting position of the limiting ball 19 on the piston plate 18. The piston plate 18 drives the gas guide member 8 to move upward together, stores the gas and compresses the fourth elastic member. When the gas guide member 8 moves to the end of the stroke and the rotating plate 11 releases the blockage of the gas guide member 8, the piston plate 18 moves downward and resets under the action of the fourth elastic member, and discharges the gas in the gas storage chamber through the gas guide member 8 into the gas storage cover 7, and then repeats the above steps, thereby accelerating the efficiency of the gas being sprayed into the collecting tube 9 from the gas storage cover 7.

[0049] As an improvement to the above solution, refer to Figure 8 The thickness of the sealing gasket 181 gradually decreases from the side away from the axis of the air guide 8 to the side close to the axis of the air guide 8.

[0050] In the above scheme, the thickness of the sealing gasket 181 is gradually changed from the outside to the inside, thereby ensuring that when the sealing gasket 181 moves downward with the piston plate 18, the outer side of the sealing gasket 181 first contacts the fixed shell 6, and then in the process of the sealing gasket 181 moving downward, the contact area between the sealing gasket 181 and the fixed shell 6 gradually increases, squeezing the adjacent air guide 8 at the axis, thereby increasing the cleanliness of the piston plate 18 when discharging the lower side gas, thereby avoiding the impact of gas residue on the detection accuracy. At the same time, because the sealing gasket 181 can be deformed, it will not affect the state of the piston plate 18 and the fixed shell 6 when they are in contact.

[0051] As an improvement to the above solution, refer to Figure 3 and Fig. 9 The collecting tube 9 is fixedly connected to and communicated with a vent 20 on one side away from the fixed shell 6. An air guide plate 21 is fixedly connected to the vent 20. The air guide plate 21 is slidably connected to a sliding member 22, and the two are sealed together.

[0052] In the above scheme, the gas entering the collecting tube 9 is finally discharged upward from the vent 20. The air guide plate 21 and the sliding member 22 are both provided with through holes, and the through holes of the two are staggered. Figure 3When the collecting cylinder 9 is in an inverted state, the sliding member 22 falls downward under its own gravity, causing the sliding member 22 to lose the seal with the air guide plate 21. Figure 1 When in the upright state, the sliding member 22 fits against the air guide plate 21 under the water pressure, thereby ensuring the seal between the sliding member 22 and the air guide plate 21 to prevent the solution from leaking out.

[0053] As an improvement to the above solution, refer to Figure 1 and Fig.10 , and further includes: an electric telescopic rod 23, which is fixedly connected to the mounting frame 1, and a drying device 24 is fixedly connected to the telescopic end of the electric telescopic rod 23, and the drying device 24 is used to dry the liquid remaining on the gas storage cover 7.

[0054] In the above scheme, the electric telescopic rod 23 is electrically connected to the remote control terminal, and the drying device 24 is an existing device, which is also electrically connected to the remote control terminal. After the gas in a collection cylinder 9 is collected, the device is in Fig.10 In the state shown, the remote control terminal controls the transmission device 3 to drive the fixed shell 6 to rotate to the upper side of the drying device 24, and controls the telescopic end of the electric telescopic rod 23 to drive the drying device 24 to extend upward, and starts the drying device 24, so that the drying device 24 dries the residual solution in the fixed shell 6 and the gas storage cover 7 to prevent the solution from adhering to the outside of the gas storage cover 7, so that the residual solution enters other collecting tubes 9, thereby ensuring the accuracy of gas collection by the collecting tube 9.
