Description

Technical Field

[0001] This invention relates to the field of sanitary ware, and in particular to a deodorizing device and a toilet. Background Technology

[0002] When toilets are in use, residual odors can cause a strong smell, affecting the environment. The most effective way to deodorize a toilet is to quickly remove these odors from the bathroom. Therefore, many toilets with built-in deodorizing functions have been developed. Currently, toilets with deodorizing functions mainly employ two types of deodorizing devices: one uses deodorizing media, such as activated carbon, negative ions, and catalysts. The deodorizing principle involves a fan drawing in odorous gases and passing them through the deodorizing media for deodorization. However, these media generally suffer from insufficient decomposition and adsorption capacity, as well as decreased adsorption saturation, leading to reduced deodorizing performance and inconvenient replacement of consumables, resulting in poor deodorizing effects and impacting the user experience. The other type uses direct-discharge deodorization, extracting the odorous gases and discharging them into the toilet's drain pipe or sewer pipe. To prevent backflow of odorous gases after the extraction stops, the market primarily uses mechanical sealing components and water seals. However, mechanical sealing components connect to the sewer pipe, which contains highly corrosive gases, creating a harsh operating environment. This places high demands on the corrosion resistance and manufacturing quality of the mechanical sealing components, and long-term use carries a risk of failure. Water seal structures are more resistant to corrosion from sewage pipes than mechanical seal structures, and the requirements for material selection and manufacturing precision of parts are lower. However, water seal structures have the following drawbacks: the water in the seal is usually in a stagnant state and will slowly evaporate if not replenished in time, causing the water seal function to gradually fail; the water in the seal is not frequently replaced, and since it is in constant contact with the sewage pipes, it is easily contaminated by bacteria in the sewage pipes. Subsequently, the bacteria and other substances in the water seal will evaporate and spread along the air duct into the toilet, thus causing pollution to the toilet and the indoor space. Summary of the Invention

[0003] This invention addresses the technical problems existing in the prior art by providing a deodorizing device and toilet that can replenish and replace the water in the water seal, thereby preventing the failure of the water seal function and preventing the spread of pollution.

[0005] Furthermore, the water seal water replacement structure includes an inlet channel and an outlet channel. The diameter of one end of the outlet channel is larger than the diameter of one end of the inlet channel, and one end of the outlet channel is fitted outside one end of the inlet channel and located inside the water seal cavity. One end of the outlet channel forms the water inlet, and the other end of the outlet channel forms the outlet. When the inlet channel stops receiving water, the water in the outlet channel flows back to replenish the water seal cavity.

[0006] Furthermore, the bottom surface of the water seal cavity is provided with an upwardly extending and enclosed water-retaining wall, which is located outside the water inlet and the top of the water-retaining wall is higher than the water inlet; it also includes a connecting pipe connected to the air outlet, the air outlet of the connecting pipe is located inside the water seal cavity and outside the water-retaining wall, and the air outlet of the connecting pipe is lower than the top of the water-retaining wall and higher than the inner bottom surface of the water seal cavity.

[0007] Furthermore, the water inlet channel includes an inlet pipe and a first inner pipe located within the water seal cavity. The free end of the first inner pipe extends upward and forms one end of the water inlet channel. The inlet pipe is located outside the water seal cavity, and one end of it is connected to the first inner pipe. The water outlet channel includes an outlet pipe and a second inner pipe located within the water seal cavity. The free end of the second inner pipe extends downward and forms one end of the water outlet channel. The outlet pipe is located outside the water seal cavity, and one end of it is connected to the second inner pipe. The other end of the outlet pipe forms the other end of the water outlet channel.

[0008] Furthermore, the water seal component includes an upper shell and a lower cover with an opening at the bottom. The bottom end of the upper shell is sealed to the lower cover to form the water seal cavity. The lower cover is provided with the first inner tube, and the upper shell is provided with the exhaust port and the second inner tube.

[0009] Furthermore, the water seal and water displacement structure is supplied with water by a water supply component, which is used to provide flushing water for the sanitary ware. The water supply component includes a flushing valve or water pump for the sanitary ware, and the water outlet is connected to the flushing port of the sanitary ware and a spray head is connected to the water outlet.

[0010] Furthermore, the exhaust port and / or fan assembly is equipped with a one-way valve to prevent odor backflow.

[0011] Furthermore, the fan assembly includes a fan and a housing component. The fan is mounted on the housing component, and the housing component is provided with an air duct.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. Since the present invention also includes a water seal water replacement structure, the water seal water in the water seal cavity is replenished and replaced by the water seal structure. This invention can not only prevent the water seal water from evaporating and losing its water seal function, but also solve the problem that the water seal water is contaminated by bacteria due to infrequent water seal water replacement, which in turn contaminates bathroom fixtures and sanitary places.

[0016] 2. The water seal and water displacement structure includes an inlet channel and an outlet channel. The part where the two are fitted together generates a Venturi effect, thereby automatically extracting water from the water seal cavity using negative pressure. Therefore, the water seal and water displacement structure is not only simple in structure, but also does not require additional pumping power, which helps to simplify the structure and reduce production costs.

[0017] 3. The water-blocking wall ensures that the water seal water in the water seal cavity will not be completely extracted during water replacement, thus ensuring the water seal effect during the water seal water replacement process and preventing odor backflow.

[0018] 4. The water seal and water displacement structure is supplied with water by a water supply component, which provides flushing water to the sanitary ware. This eliminates the need for additional power supply to the water seal and water displacement structure, thus simplifying the structure and reducing production costs. The water outlet connects to the flushing port of the sanitary ware, eliminating the need for additional drainage channels when the deodorizing device is applied to sanitary ware, further simplifying the structure and reducing production costs.

[0019] 5. The exhaust port and / or fan assembly are equipped with a one-way valve, which can further prevent the backflow of odorous gas, thereby improving the effect of the deodorization device of the present invention in preventing the backflow of odorous gas.

The upper shell 11 is provided with an exhaust port 111, a second inner tube 112, and a connecting tube 113. Specifically, the second inner tube 112 and the connecting tube 113 are integrally formed with the upper shell 11.

[0042] In this embodiment, the water seal and water displacement structure is supplied with water by a water supply component, which is used to provide flushing water for the bathroom fixtures, but is not limited to this. The water supply component includes a flush valve or water pump for the bathroom fixtures. Specifically, the water supply component is the flush valve 30 of the bathroom fixtures. The water outlet 71 is connected to the flush port 103 of the bathroom fixtures, and the water outlet 71 is connected to a shower head 20.

[0043] In this embodiment, the exhaust port 111 and / or the fan assembly 3 are equipped with a one-way valve 4. Specifically, the exhaust port 111 is equipped with a one-way valve 4, such as... Figure 3 As shown, the one-way valve 4 is used to prevent the backflow of odorous gases.

[0045] The present invention provides a deodorizing device that can be applied to bathroom fixtures such as toilets. Its working principle when applied to toilets is as follows.

[0046] Please see Figures 1-15 As shown, a toilet of the present invention includes a toilet seat 10, a toilet lid (not shown in the figure) and a deodorizing device 40. The deodorizing device 40 adopts the deodorizing device described in the above embodiment. The air inlet 331 is connected to the toilet bowl cavity 101 of the toilet seat 10, and the exhaust port 111 is connected to the drain pipe 102 of the toilet seat 10.

[0047] In this embodiment, the water seal and water displacement structure is supplied with water by a water supply component for providing flushing water to the toilet seat 10. The water supply component includes a flush valve or a water pump for the toilet seat 10. Specifically, the toilet of the present invention is a tankless toilet, and the water supply component is the flush valve 30 of the toilet seat 10. The water outlet 71 is connected to the flush port 103 of the toilet seat 10, and the water outlet 71 is connected to a nozzle 20. In other embodiments, the toilet of the present invention has a water tank, and water from the tank is pumped out by a water pump to flush the toilet seat. In this case, the water supply component is a water pump.

[0048] In this embodiment, the toilet of the present invention is a smart toilet, therefore, the toilet seat is a smart toilet seat, and the deodorizing device 40 is installed on the smart toilet seat.

[0049] The working principle of the deodorization device 40 is as follows:

[0050] 1. Deodorization Operation: When the blower 31 is turned on, it draws the odorous gas from the toilet bowl cavity 101 into the water seal cavity 13. Under the air pressure of the blower 31, the odorous gas passes through the water seal, and the valve cover of the one-way valve 4 opens due to the air force. The odorous gas then enters the drain pipe 102 along the exhaust pipe 5 for deodorization. Figure 6 , Figure 7As shown in the figure, the arrows indicate the direction of the airflow.

[0051] 2. Anti-backflow odor operation: When the fan 31 is not turned on, the valve cover of the one-way valve 4 falls under its own weight and remains in a sealed state. The one-way valve 4 and the water seal prevent gas in the drain pipe 102 from entering the toilet, thus preventing backflow odor and preventing harmful bacteria in the drain pipe 102 from growing and spreading into the toilet. Figure 8 , Figure 9 As shown in the figure, the arrow indicates the direction of the backflow of odor in the sewage pipe 102.

[0052] 3. Water seal and water replacement working condition:

[0053] (1) Initial state: When the toilet is not flushed, the water seal height in the water seal chamber 13 is H1, such as Figure 10 , Figure 11 As shown, when the toilet is initially started to flush, the direction of the flushing water flow is: flush valve 30 - inlet pipe 6 - first inner pipe 122 - second inner pipe 112 - outlet pipe 7 - flushing port 103 - toilet bowl cavity 101.

[0054] (2) Intermediate state of water seal water replacement: The high-speed water flow forms a negative pressure area around the water inlet 1121, drawing out the water seal water in the water seal cavity 13 around the water inlet 1121, such as Figure 13 As shown in the figure, the dashed lines indicate the direction of water flow; the extracted water is discharged into the toilet bowl cavity 101 through the nozzle 20. Because the lower cover 12 is equipped with a water-blocking wall 121 of height H2, the water seal in the water seal cavity 13 drops to a height of H2, and its surrounding area becomes waterless, so the water level no longer drops. The water seal in the water seal cavity 13 maintains a constant height of H2, meaning the water seal height decreases from H1 to H2. The volumes v1 and v2 corresponding to heights H1 and H2 represent the volume of water seal water discharged each time the toilet is flushed: v1 - v2. Because the air outlet of the connecting pipe 113 on the upper shell 11 is located at a depth S below the top of the water-blocking wall 121, and because the water seal is maintained at a height of H2 and not completely extracted, the odor in the toilet drain pipe 102 is still isolated by the water seal at a height of H2 during the flushing process. Figure 13 As shown in the figure, the thin solid line and the arrow on it indicate the path of the odor, thereby preventing the odor from flowing back into the toilet through the water seal cavity 13 and the connecting pipe 113.

[0055] (3) Water seal water replacement recovery state: The outlet pipe 7 and nozzle 20 are positioned at a height X above the water seal cavity 13. When flushing ends, the flushing valve 30 stops supplying water. Due to the height difference X, the water in the outlet pipe 7 will flow back to the water seal cavity 13 under gravity. The water flow direction is: outlet 71 - outlet pipe 7 - second inner pipe 112 - water inlet 1121 - water seal cavity 13. Figure 15As shown in the diagram, the dashed lines and arrows indicate the direction of water flow. The length of the outlet pipe 7 is L, and its diameter is D. The data relationship satisfies v1 - v2 = πD. 2 L / 4 means that the amount of water stored in the outlet pipe 7 is equal to the amount of water discharged from the water seal chamber 13 during flushing. After the water stored in the outlet pipe 7 flows back, the water seal water returns to its initial position, that is, the water seal water height is restored from H2 to H1, and the water seal water is replenished and replaced by the newly flowing tap water.

[0056] The theoretical formula for calculating the water replacement concentration t in the water seal is as follows:

[0057] Assume that the initial state of the water seal replacement structure contains pure wastewater of volume v1, and that the concentration of the wastewater is uniform before and after water replacement:

[0058] Initial concentration: t0 = v1 / v1 = 1

[0059] Concentration after the first displacement: t1=[v1-(v1-v2)t0] / v1

[0060] Concentration after the second displacement: t2=[v2-(v1-v2)t1] / v1

[0061] Concentration after the third displacement: t3 = [v2 - (v1 - v2)t2] / v1

[0062] Concentration after the 4th replacement: t4 = [v2 - (v1 - v2)t3] / v1

[0063] Concentration after the 5th replacement: t5 = [v2 - (v1 - v2)t4] / v1

[0064] Concentration after the nth displacement: t n =[v2-(v1-v2)t n-1 ] / v1

[0065] The above analysis allows us to calculate the displacement concentration after flushing, and based on the displacement concentration t... n The requirements (impact assessment of hazardous substances in wastewater) guide the design of values ​​for v1 and v2. The more replacement cycles, the lower the concentration after replacement, and the cleaner the water seal water.

[0066] This invention discloses a deodorizing device and toilet. By incorporating a water seal and water replacement structure within the deodorizing device, the water in the water seal cavity is replenished and replaced. This not only prevents the water seal from evaporating and losing its function but also solves the problem of bacterial contamination of the water seal cavity due to infrequent water replacement, which can then contaminate bathroom fixtures and other sanitary areas. Specifically, the water seal and water replacement structure utilizes the Venturi effect to generate negative pressure, automatically extracting water from the water seal cavity. Therefore, the structure is simple and requires no additional pumping power, thus simplifying the design and reducing production costs.

[0067] The deodorizing device and toilet of the present invention are identical to or can be implemented using existing technology for the parts not described herein.

[0068] The above embodiments are only used to further illustrate a deodorizing device and toilet of the present invention, but the present invention is not limited to the embodiments.
