Description

Technical Field

[0001] This utility model relates to the field of bathroom equipment technology, and in particular to a deodorizing and liquid-changing device and a toilet. Background Technology

[0002] Smart toilets typically include an odor control function to enhance the user experience.

[0003] Current smart toilets typically include an air extraction device to draw odors from the toilet bowl into the drain pipe, thus deodorizing. However, this method is insufficient and odors can easily escape. Existing smart toilets also use deodorizing liquids such as electrolytes to eliminate odor substances in the airflow, preventing further odor escape. However, existing deodorizing liquid devices can only treat a fixed amount of odor; liquid replacement and replenishment are not possible during the treatment process, affecting the overall deodorizing effect.

[0004] Therefore, there is an urgent need for a deodorizing and liquid-changing device and toilet to solve the above problems. Utility Model Content

[0010] The air inlet is located on the drain path of the deodorizing space. The deodorizing liquid can be contained in the deodorizing space under the pressure of the airflow, and can be discharged from the deodorizing space through the drain path when the air pressure of the airflow is less than the hydraulic pressure in the deodorizing space.

[0011] As a preferred embodiment of the deodorizing liquid replacement device provided by this utility model, the deodorizing module is provided with a porous partition, the deodorizing space is formed above the porous partition, and the air inlet is located below the porous partition.

[0012] As a preferred embodiment of the deodorization and liquid replacement device provided by this utility model, the deodorization module forms an exhaust port and a liquid outlet at its two ends in the direction of gravity, respectively. The deodorized airflow can be discharged through the exhaust port, and the reacted liquid can be discharged through the liquid outlet.

[0013] As a preferred embodiment of the deodorizing and liquid-changing device provided by this utility model, the exhaust port and the liquid outlet are set at an angle to each other.

[0016] As a preferred embodiment of the deodorizing liquid replacement device provided by this utility model, the deodorizing liquid replacement device further includes a liquid tank, and the outlet of the drain path is connected to the liquid tank, so that the reacted liquid discharged through the drain path can be contained in the liquid tank;

[0017] The liquid tank is connected to the electrolysis assembly, and the liquid in the liquid tank can enter the electrolysis assembly for electrolysis.

[0018] As a preferred embodiment of the deodorizing liquid replacement device provided by this utility model, the deodorizing module is provided with an overflow pipe, the inlet of which is positioned at a height corresponding to the bottom of the deodorizing space, and the overflow pipe can discharge the deodorizing liquid that has reacted at the bottom of the deodorizing space.

[0019] As a preferred embodiment of the deodorizing and liquid-changing device provided by this utility model, the airflow drive module includes an air inlet pipe and an airflow drive component connected to each other. The air inlet pipe is connected to the toilet bowl, and the airflow drive component is connected to the air inlet.

[0024] The deodorizing module forms an internal deodorizing space. An airflow drive module is connected to the air inlet of this deodorizing space, allowing airflow from the drive module to enter. The deodorizing space is equipped with a liquid inlet, through which deodorizing liquid enters. This liquid absorbs odor substances from the airflow.

The deodorizing liquid can be contained within the deodorizing space under the pressure of the airflow, and can be discharged from the deodorizing space through the drainage path when the airflow pressure is lower than the hydraulic pressure within the deodorizing space. This design enables the replacement of the deodorizing liquid, simplifies the replacement process, and improves the deodorizing effect. Attached Figure Description

[0052] Example 1

[0053] This embodiment provides a deodorizing and fluid-changing device and a toilet. The toilet includes a toilet bowl and the deodorizing and fluid-changing device provided in this embodiment. The deodorizing and fluid-changing device can suck up and deodorize the airflow in the toilet bowl.

[0054] Figure 1 This diagram shows the structure of the deodorizing liquid replacement device provided in Embodiment 1 of the present invention; Figure 2 This diagram shows a partial structural schematic of the deodorizing liquid replacement device provided in Embodiment 1 of this utility model; Figure 3 This is an axial sectional view showing a portion of the structure of the deodorizing liquid replacement device provided in Embodiment 1 of this utility model. (Refer to...) Figures 1-3 The deodorizing liquid replacement device includes an airflow drive module 100 and a deodorizing module 200.

[0055] Specifically, the airflow drive module 100 can draw airflow from the toilet bowl, thereby reducing odor escape and improving the subsequent deodorization effect. The deodorization module 200 forms a deodorization space 210, and the airflow drive module 100 is connected to the air inlet 211 of the deodorization space 210, allowing airflow from the airflow drive module 100 to enter the deodorization space 210. The deodorization space 210 is provided with a liquid inlet 212, through which deodorizing liquid can enter. The deodorizing liquid absorbs odor substances in the airflow, and the deodorized airflow and reacted liquid are discharged separately from the deodorization space 210. Through the deodorization space 210, the airflow and deodorizing liquid are concentrated in one space, achieving sufficient contact and reaction between the two, effectively preventing odor escape and thus improving the deodorization effect. The air inlet 211 is located on the drainage path of the deodorizing space 210. The deodorizing liquid can be contained in the deodorizing space 210 under the action of air pressure, and can be discharged from the deodorizing space 210 through the drainage path when the air pressure is lower than the hydraulic pressure in the deodorizing space 210. Through the above configuration, the liquid replacement process of the deodorizing liquid can be realized by controlling air pressure and hydraulic pressure, simplifying the liquid replacement method and improving the deodorizing effect.

[0056] More specifically, the deodorization module 200 has an exhaust port 230 and a drain port 240 at its two ends in the direction of gravity, and the deodorization space 210 is formed between the exhaust port 230 and the drain port 240. The deodorized airflow can be discharged through the exhaust port 230, and the liquid with reduced or completely consumed deodorizing substance content after reaction can be discharged through the drain port 240.

[0057] Preferably, the exhaust port 230 and the drain port 240 are arranged at an angle to each other. In this embodiment, the drain port 240 is opened downwards in the direction of gravity, and the exhaust port 230 is opened horizontally, that is, the exhaust port 230 and the drain port 240 are arranged at right angles to each other. This arrangement facilitates liquid discharge and prevents the airflow entering the air inlet 211 from directly escaping through the exhaust port 230, increasing the airflow discharge path, prolonging the contact time between the airflow and the deodorizing liquid, and improving the deodorizing effect of the reaction.

[0058] More specifically, the deodorizing liquid replacement device also includes a liquid tank 300. The drain port 240 is connected to the liquid tank 300, and the reacted liquid discharged through the drain port 240 can be temporarily contained in the liquid tank 300. In this embodiment, the liquid tank 300 can be a toilet tank or a separately installed container capable of temporarily storing liquid.

[0059] Preferably, the drain port 240 extends below the liquid level of the liquid tank 300. This configuration liquid-seales the deodorization module 200, preventing airflow inside the module from escaping through the drain port 240 and causing odor to dissipate.

[0060] It should be noted that when the liquid tank 300 is a toilet tank, the liquid tank 300 also needs to be equipped with a liquid tank inlet pipe 310 to connect to a water source in order to replenish the water for flushing the toilet.

[0061] Figure 4 This diagram illustrates a porous partition provided in Embodiment 1 of the present invention. (Refer to...) Figure 3 and Figure 4 The deodorizing module 200 is equipped with a porous partition 220, which has several ventilation holes 221. The deodorizing space 210 is formed above the porous partition 220, and the air inlet 211 is located below the porous partition 220. Airflow entering through the air inlet 211 can pass through the ventilation holes 221 on the porous partition 220 into the deodorizing space 210. This arrangement allows the gas to undergo a bubbling reaction in the deodorizing liquid, enhancing the chemical reaction effect. Furthermore, the multiple ventilation holes 221 disperse the airflow from a single mass into multiple smaller streams, thereby increasing the contact area with the deodorizing liquid and improving the deodorization rate.

[0062] Preferably, the diameter of the vent 221 is 3-5 mm. If the opening is too small, the liquid will block the vent 221. If the opening is too large, it will not be enough to disperse the airflow into a small part of the reaction.

[0063] Continue to refer to Figure 1 The deodorizing liquid replacement device also includes a deodorizing module 400. The deodorizing module 400 is connected to the liquid inlet 212 and can provide deodorizing liquid to the deodorizing space 210.

[0064] In this embodiment, the deodorization module 400 includes an electrolysis component 410, which is connected to the inlet 212 via an electrolysis component supply pipe 430 and to a water source via an electrolysis component inlet pipe 420. The electrolysis component 410 can electrolyze tap water to form a deodorizing liquid such as hypochlorous acid.

[0065] Preferably, the liquid tank 300 can also be selectively connected to the electrolysis component 410 via the electrolysis component inlet pipe 420. The liquid in the liquid tank 300 can enter the electrolysis component 410 for electrolysis, realizing the repeated recycling of the liquid to save water resources.

[0066] Alternatively, in other embodiments, the deodorization module 400 may contain the deodorizing liquid. That is, the deodorization module 400 may be a container capable of holding the deodorizing liquid and supplying it to the inlet 212.

[0067] It should be noted that the deodorizing liquid replacement device also includes a control valve 500. The liquid tank inlet pipe 310, the electrolysis component supply pipe 430, and the toilet drain pipe (not shown) are all connected to the control valve 500. The control valve 500 can operate to connect or disconnect the water source and the liquid tank inlet pipe 310 to control the replenishment of water to the liquid tank 300; the control valve 500 can operate to connect or disconnect the liquid tank 300 and the electrolysis component inlet pipe 420 to control the recycling of liquid in the liquid tank 300; the control valve 500 can also operate to connect or disconnect the electrolysis component inlet pipe 420 and the water source, thereby controlling the supply of water to the electrolysis component 410. In this embodiment, the control valve 500 can specifically be a solenoid valve as in the prior art, and its specific structure will not be described in detail here.

[0068] Continue to refer to Figure 1 The airflow drive module 100 includes an air inlet pipe 110 and an airflow drive assembly 120 connected to each other. The air inlet pipe 110 is connected to the toilet bowl, and the airflow drive assembly 120 is connected to the air inlet 211. When the airflow drive assembly 120 rotates forward, it can draw airflow from the toilet bowl into the air inlet 211 through the air inlet pipe 110; when the airflow drive assembly 120 rotates in reverse, it can also draw airflow out of the deodorization module 200. In this embodiment, the airflow drive assembly 120 can specifically be a fan in the prior art.

[0069] It should be noted that during the deodorization process, the airflow drive module 100 must first be activated to create a certain air pressure support below the deodorization space 210. Then, the deodorizing liquid is introduced into the deodorization space 210 through the liquid inlet 212, and the pressure of the liquid is less than the air pressure. At this time, the deodorizing liquid in the deodorization space 210 will be kept in the deodorization space 210 under the action of air pressure and will not flow out through the drainage path under the action of gravity.

[0070] Figure 5 A flowchart illustrating the deodorization control method provided in Embodiment 1 of this utility model is shown. (Refer to...) Figure 5 This embodiment also provides a deodorization control method. This deodorization control method is specifically based on the deodorization liquid replacement device provided in this embodiment. The deodorization control method specifically includes the following steps:

[0071] Step S10: Start the deodorization program.

[0072] Specifically, in this embodiment, a pressure sensor is installed on the toilet seat. When the pressure sensor senses that the user has sat down, the deodorization program is automatically activated.

[0073] Alternatively, in other embodiments, the deodorization procedure can be started by the user via remote control or the like.

[0074] Step S20: Start the airflow drive module 100 to draw airflow from the toilet bowl.

[0075] Step S30: After the airflow drive module 100 has reached the preset suction time, the deodorizing liquid is introduced into the deodorizing space 210 to carry out the deodorization process.

[0076] Specifically, in this embodiment, the preset suction time is selected as 1 second, so that air pressure support can be formed below the gravity direction of the deodorization space 210.

[0077] Step S40: After the deodorization process reaches the single deodorization time, the airflow drive module 100 is stopped. At this time, the liquid in the deodorization space 210 loses the support of air pressure and is discharged from the deodorization module 200 through the drain port 240 under the action of gravity.

[0078] Specifically, in this embodiment, the deodorization duration per cycle can be selected based on the concentration of the deodorizing liquid that the electrolysis component 410 can prepare and the amount of liquid entering the inlet 212 at a time. For example, when the airflow rate of a single suction cycle is 6 m³ / h, and the amount of liquid entering the inlet 212 at a time is 50 ml of hypochlorous acid liquid with a concentration of 80 ppm, the deodorization duration per cycle is specifically two minutes and thirty seconds. To ensure continuous deodorization, the deodorization duration per cycle can be set to two minutes to ensure that the liquid in the deodorization space 210 retains its deodorizing capacity throughout the deodorization duration.

[0079] In step S50, after the airflow drive module 100 stops and reaches the required drainage time, steps S20-S40 are repeated until the deodorization process stops.

[0080] Specifically, experimental verification showed that the drainage time required to completely drain 50ml of liquid is three seconds. This drainage time can also be selected as 2 seconds, 4 seconds, or 5 seconds, depending on the volume of liquid in the deodorizing space 210, as long as the liquid in the deodorizing space 210 can be completely drained.

[0081] Preferably, when draining the deodorization space 210, the liquid in the deodorization space 210 can be discharged more quickly by reversing the airflow drive component 120.

[0082] More specifically, in this embodiment, the deodorization program automatically stops when the pressure sensor on the toilet seat detects that the user has changed from a seated state to a non-seated state. In other embodiments, the deodorization program can also be stopped by the user via remote control or the like.

[0083] Example 2

[0084] This embodiment provides a deodorizing and fluid-changing device and a toilet.

[0085] Figure 6 This diagram shows the structure of the deodorizing liquid replacement device provided in Embodiment 2 of this utility model; Figure 7 An axial sectional view of the deodorizing fluid replacement device provided in Embodiment 2 of this utility model is shown. (Refer to...) Figure 6 and Figure 7 The difference between this embodiment and Embodiment 1 is that the deodorizing module 200 provided in this embodiment is further provided with an overflow pipe 250. The inlet height of the overflow pipe 250 corresponds to the lowest point of the deodorizing space 210, and the overflow pipe 250 can discharge the deodorizing liquid that has reacted at the bottom of the deodorizing space 210. During the continuous introduction of deodorizing liquid into the deodorizing space 210, by providing the overflow pipe 250, the deodorizing liquid at the bottom of the deodorizing space 210 with a reduced concentration of reacted liquid can be discharged, realizing the gradual replacement of the deodorizing liquid in the deodorizing space 210.

[0086] Specifically, the outlet of the overflow pipe 250 is connected to the top of the liquid tank 300 and is located above the liquid level in the liquid tank 300 to ensure that the liquid in the overflow pipe 250 is smoothly discharged into the liquid tank 300.

[0087] More specifically, the overflow pipe 250 has an arc-shaped structure, with its middle section bending towards a direction higher than the inlet. After reaching the highest point of the middle section, it bends downwards in the direction of gravity, forming an outlet at the end. The highest point of the middle section of the overflow pipe 250 is the overflow height. When the liquid level in the deodorization space 210 reaches the overflow height, the liquid at the bottom of the deodorization space 210 can enter the inlet of the overflow pipe 250 and flow out from the outlet.

[0088] In this embodiment, when the deodorization program is started, the airflow drive module 100 draws airflow from the toilet bowl. After the airflow drive module 100 draws for a preset time, the deodorizing liquid is introduced into the deodorization space 210. It should be noted that the liquid level in the deodorization space 210 should be kept below the overflow height during the first liquid introduction to prevent the deodorizing liquid from flowing directly into the liquid tank 300 through the overflow pipe 250 before reacting.

[0089] After a period of time, due to the reaction, the concentration of the deodorizing liquid decreases. A certain amount of deodorizing liquid is injected into the inlet 212 again, and the overall liquid level in the deodorizing space 210 rises to the overflow height. The deodorizing liquid that has already reacted at the bottom enters the liquid tank 300 through the overflow pipe 250, and the new deodorizing liquid continues to react with the odorous substances in the airflow, realizing the replacement of the old liquid with the new liquid.

[0090] The above-mentioned process of liquid injection and overflow drainage continues until the deodorization procedure is stopped.

[0091] Example 3

[0092] This embodiment provides a deodorizing and fluid-changing device and a toilet.

[0093] Figure 8 A top view showing a portion of the structure of the deodorizing liquid replacement device provided in Embodiment 3 of this utility model is shown. Figure 9 This is an axial sectional view showing a portion of the structure of the deodorizing and fluid-changing device provided in Embodiment 3 of this utility model. (Refer to...) Figure 8 and Figure 9 The difference between this embodiment and embodiment one is that in this embodiment, there are two deodorizing modules 200, and the deodorizing spaces 210 of the two deodorizing modules 200 are alternately connected to the airflow drive module 100. The deodorizing liquid is alternately introduced into the deodorizing spaces 210 of the two deodorizing modules 200 to achieve continuous deodorization.

[0094] Specifically, an air inlet pipe 610 connects the air inlets 211 of the two deodorizing modules 200. The airflow drive assembly 120 is connected to the middle of the air inlet pipe 610, and the two air inlets 211 are located on both sides of the airflow drive assembly 120. The airflow drawn by the airflow drive assembly 120 can enter either of the two air inlets 211.

[0095] More specifically, an air intake regulating plate 630 is provided at the connection between the airflow drive assembly 120 and the air intake pipe 610 of the deodorizing module. The air intake regulating plate 630 is swayably installed inside the air intake pipe 610 of the deodorizing module and can swing to block one air intake 211 from the airflow drive assembly 120, or block the other air intake 211 from the airflow drive assembly 120.

[0096] More specifically, a deodorizing module inlet pipe 620 connects the inlets 212 of the two deodorizing modules 200. The electrolysis component supply pipe 430 of the deodorizing module 400 is connected to the middle of the deodorizing module inlet pipe 620, and the two inlets 212 are located on opposite sides of the deodorizing module 400. The deodorizing liquid supplied via the electrolysis component supply pipe 430 can enter either of the two inlets 212.

[0097] More specifically, an inlet regulating plate 640 is provided at the connection between the electrolysis component supply pipe 430 and the deodorization module inlet pipe 620. The inlet regulating plate 640 is swayably installed inside the deodorization module inlet pipe 620 and can swing to block one inlet 212 from the electrolysis component supply pipe 430, or block the other inlet 212 from the electrolysis component supply pipe 430.

[0098] In this embodiment, when the deodorization program is activated, both the air intake regulating plate 630 and the liquid intake regulating plate 640 are automatically adjusted and swung to the right, allowing only airflow and deodorizing liquid to enter the left deodorization space 210, where they react in the left deodorization module 200. After a single deodorization cycle, the swaying direction of the air intake regulating plate 630 and the liquid intake regulating plate 640 is changed so that they both swung to the left. At this time, the air pressure in the left deodorization space 210 returns to zero, and the liquid in the left deodorization space 210 flows back to the liquid tank 300. Then, the airflow and deodorizing liquid enter the right deodorization space 210, where they react in the right deodorization module 200. The above steps are continuously repeated until the deodorization program stops.
