Description

Technical Field

[0001] The invention relates to the technical field of bathroom products, and in particular to a detergent slow-release device and water-using equipment. Background Art

[0002] Bathroom products include toilets, urinals, basins, showers, etc. Affected by water quality, scale is easy to appear in the shower head and pipes, blocking the water outlet of the shower head. Affected by water quality, scale is also easy to appear on the surface of the basin, affecting the user experience. Affected by water quality, urine, and dirt, scale is easy to appear on the ceramic surface and pipes of toilets and urinals, and it is easy to produce odor.

[0003] In the prior art, the cleaning methods of sanitary products include manual cleaning and automatic cleaning. The manual cleaning method has a poor user experience and is difficult to clean scale in the pipes. The automatic cleaning method includes installing a detergent release device on the water supply pipe of the sanitary product.

[0004] The detergent release device in the prior art includes a shell, which has a cavity for accommodating solid detergent or liquid detergent. The shell is provided with a water inlet and a drain with a smaller aperture. Generally, the water inlet is provided at the upper part of the shell, and the drain is provided at the lower part of the shell. When installed on a sanitary product, the detergent release device is connected to the outlet pipe of the water inlet control valve of the sanitary product. The outlet pipe is correspondingly provided with a venturi tube or the like, the water inlet is connected to the upstream end of the venturi tube, and the drain is connected to the downstream end of the venturi tube. The water pressure at the upstream end of the venturi tube is greater than the water pressure at the downstream end, so a small amount of water will enter the cavity through the water inlet and mix with the detergent in the cavity, and then a small amount of detergent will enter the water outlet pipe from the drain, and finally enter the sanitary product through the water outlet pipe to clean the sanitary product.

[0005] Existing detergent release devices have the following defects:

[0006] During the whole process of using water for bathroom products, the detergent release device will keep supplying detergent to the bathroom products. Since detergent is supplied during the water use process, the previous detergent will be washed away with the water, thus resulting in a large amount of detergent waste. Since detergent is supplied during the water use process, it cannot be used for showers, wash basins, etc., so as not to affect user use. Summary of the invention

[0080] The specific embodiments of the present invention are further described below in conjunction with the accompanying drawings. The same components are represented by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0081] like Figure 1-11 Combined with Fig. 20 As shown, a detergent slow-release device provided by one embodiment of the present invention includes a detergent slow-release device 100 and a discharge pipe 200 connected to the detergent slow-release device 100 , and the discharge pipe 200 is used to be connected to the water outlet pipe 402 of the water control valve 400 of the water device 500 .

[0082] The detergent slow-release device 100 includes a storage chamber 3 for storing detergent and a slow-release chamber 4 for releasing detergent and having a variable volume. One end of the discharge pipe 200 is connected to the slow-release chamber 4 .

[0083] A channel 61 is provided between the storage chamber 3 and the slow-release chamber 4 , and a slow-release control valve 7 is installed in the channel 61 . The slow-release control valve 7 can switch between a closed state and an open state as the volume of the slow-release chamber 4 changes.

[0084] When the discharge pipe 200 injects water into the slow-release chamber 4, the volume of the slow-release chamber 4 gradually increases, the slow-release control valve 7 opens, and part of the detergent in the storage chamber 3 enters the slow-release chamber 4 and mixes with water to form a diluted detergent solution.

[0085] When the discharge pipe 200 discharges liquid to the water outlet pipe 402, the volume of the slow-release chamber 4 gradually decreases and resets, the slow-release control valve 7 is closed, and the diluted detergent solution in the slow-release chamber 4 is supplied from the water outlet pipe 402 to the water device 500 for cleaning.

[0086] The detergent slow-release device provided by the present invention is used to provide detergent to the water-using device 500 to clean the water-using device 500. The water-using device 500 may be a toilet in a bathroom, a urinal 501, a basin (wash basin), a shower, a basin (sink) in a kitchen, a wash basin in a public area, etc. The detergent slow-release device is connected between the water control valve 400 and the water-using device 500. Specifically, the detergent slow-release device is connected to the water outlet pipe 402 of the water control valve 400.

[0087] The cleaning agent can be selected according to the actual scenario, for example, a cleaning agent specifically for cleaning toilets and urinals 501, a cleaning agent specifically for cleaning wash basins, wash basins, and showers, a cleaning agent specifically for cleaning kitchen sinks, etc. The cleaning agent can be a solid cleaning agent 300 or a liquid cleaning agent.

[0088] The detergent slow-release device provided by the present invention comprises a detergent slow-release device 100 and a discharge pipe 200. The detergent slow-release device 100 is used to store and release detergent. The discharge pipe 200 is used to connect the detergent slow-release device 100 and the water outlet pipe 402. The discharge pipe 200 is a connecting pipe. Since the discharge pipe 200 has a water injection state and a liquid discharge state according to the actual water pressure, the connecting pipe is called the discharge pipe 200.

[0089] The shell of the detergent slow release device 100 includes an upper shell 1 and a lower shell 2, and the upper shell 1 and the lower shell 2 can be connected by threads, or the upper shell 1 and the lower shell 2 can be integrally arranged. A spacer 6, such as a partition, is provided between the upper shell 1 and the lower shell 2. A top cover 11 is detachably mounted on the top of the upper shell 1, and a bottom cover 21 is connected to the bottom of the lower shell 2. As required, the bottom cover 21 can be integrally arranged with the lower shell 2 or detachably connected. A storage chamber 3 is formed in the upper shell 1, which is above the spacer 6 and is used to store detergent. A slow release chamber 4 is formed in the lower shell 2, which is below the spacer 6. The volume of the slow release chamber 4 of the spacer 6 is variable, and the slow release chamber bottom 41 and / or the slow release chamber wall of the slow release chamber 4 are movable, thereby realizing volume change. The slow release chamber bottom 41 and / or the slow release chamber wall can adopt structures such as slide plates, pistons, elastic diaphragms, and elastic seals to realize volume change. The slow-release chamber 4 is used to receive the detergent discharged from the storage chamber 3 and then discharge the diluted detergent solution.

[0090] The spacer 6 is provided with a channel 61 which passes through from top to bottom, and the slow-release control valve 7 is assembled in the channel 61. The slow-release control valve 7 can be a mechanical valve or an electrically controlled valve, which is used to control the delivery of the detergent from the storage chamber 3 to the slow-release chamber 4. When the slow-release control valve 7 is in a certain position or a certain state, the slow-release control valve 7 closes the channel 61, and the detergent in the storage chamber 3 cannot be delivered / discharged into the slow-release chamber 4. At this time, it is called the initial / closed state or initial / closed position of the slow-release control valve 7. When the slow-release control valve 7 is in another position or another state, the slow-release control valve 7 opens the channel 61, and the detergent in the storage chamber 3 can be directly delivered / discharged into the slow-release chamber 4, or the slow-release control valve 7 keeps the channel 61 closed, and the detergent is carried / discharged into the slow-release chamber 4 by the slow-release control valve 7. At this time, it is called the open state or open position of the slow-release control valve 7.

[0091] The opening and closing of the slow-release control valve 7 is linked to the volume change of the slow-release chamber 4. In the normal or initial state, the volume of the slow-release chamber 4 is small, and the slow-release control valve 7 is in a closed state. When water is injected into the slow-release chamber 4, the volume of the slow-release chamber 4 increases. When the volume of the slow-release chamber 4 increases to a certain extent, the slow-release control valve 7 opens. If the slow-release control valve 7 adopts a mechanical valve, the switch of the slow-release control valve 7 is completely controlled by the volume change of the slow-release chamber 4. If the slow-release control valve 7 adopts an electrically controlled valve, a corresponding sensor unit can be configured to monitor the volume change of the slow-release chamber 4, and then send a signal to the control unit, which controls the switch of the slow-release control valve 7.

[0092] A discharge port 42 is provided on one side of the slow-release chamber 4, and one end of the discharge pipe 200 is connected to the discharge port 42. The discharge pipe 200 can switch its discharge state according to the switch of the upstream water control valve 400.

[0093] When the upstream water control valve 400 is opened, the water outlet pipe 402 supplies water to the water device 500. At this time, the water pressure of the water outlet pipe 402 is greater than the water pressure of the slow-release chamber 4, so the injection pipe 200 is in a state of injecting water into the slow-release chamber 4, a large amount of water in the water outlet pipe 402 is supplied to the water device 500, and a small part of the water in the water outlet pipe 402 is injected into the slow-release chamber 4 through the injection pipe 200. The volume of the slow-release chamber 4 gradually increases, and the slow-release control valve 7 opens as the volume of the slow-release chamber 4 increases, and part of the detergent in the storage chamber 3 enters the slow-release chamber 4, and then mixes with the water entering the slow-release chamber 4 to form a detergent dilution solution.

[0094] After the water control valve 400 is closed, the water outlet pipe 402 stops supplying water to the water device 500. At this time, the water pressure in the slow-release chamber 4 is greater than the water pressure in the water outlet pipe 402, and the injection pipe 200 is in a state of discharging liquid to the water outlet pipe 402. During this process, the volume of the slow-release chamber 4 gradually decreases until it is reset to the initial state, and the slow-release control valve 7 returns to the closed state. When the injection pipe 200 is in a state of discharging liquid to the water outlet pipe 402, the diluted detergent solution in the slow-release chamber 4 is supplied to the water device 500 through the injection pipe 200 and the water outlet pipe 402 for self-cleaning of the water device 500.

[0095] In summary, the detergent slow-release device provided by the present invention only provides detergent at the end of water use of the water use device 500, that is, it starts to provide detergent after the water control valve 400 is closed. When the user uses the water use device 500, no detergent is discharged, and it will not affect the user's normal use of showers, washbasins, etc. Therefore, it can be used for toilets and urinals, as well as showers and basins, expanding the scope of application.

[0096] The detergent slow-release device provided by the present invention only provides detergent at the end of the water-using device 500, and no detergent is discharged at the beginning of the water-using device 500, thereby effectively avoiding the waste of detergent.

[0097] The detergent slow-release device provided by the present invention only provides detergent at the water-using end section of the water-using device 500. Therefore, before the user uses the water-using device 500 next time, no water will wash away the detergent from the water-using device 500. The detergent stays on the water-using device 500 for a long time, which can better dissolve scale, stains, etc. When the water-using device 500 is used next time, water will quickly and smoothly drain away the dissolved dirt on the water-using device 500, thereby improving the cleaning effect.

[0098] In one embodiment, if Figure 2 As shown, the top cover 11 is provided with a liquid replenishing port 12 which is in communication with the storage chamber 3 and is used to replenish the liquid detergent into the storage chamber 3. A plug cover 13 is mounted in the liquid replenishing port 12.

[0099] The storage chamber 3 stores liquid detergent. When the slow-release control valve 7 switches from a closed state or a closed position to an open state or an open position, the liquid detergent in the storage chamber 3 is carried / discharged into the slow-release chamber 4 by the slow-release control valve 7. The slow-release control valve 7 keeps the channel 61 closed, and the water in the slow-release chamber 4 does not enter the storage chamber 3, so as to avoid diluting the concentration of the liquid detergent in the storage chamber 3.

[0100] In one embodiment, if Figure 11-12As shown, the top cover 11 is detachably connected to the upper shell 1 so that a solid detergent 300 can be placed in the storage cavity 3 and a proper amount of water can be added. The solid detergent 300 is dissolved by water in the storage cavity 3 to form a liquid detergent. The solid detergent 300 can be completely dissolved after a period of use.

[0101] The storage chamber 3 stores the solid cleaning agent 300. When the slow-release control valve 7 switches from a closed state or a closed position to an open state or an open position, the liquid cleaning agent in the storage chamber 3 is carried / discharged into the slow-release chamber 4 by the slow-release control valve 7. The slow-release control valve 7 opens the channel 61. At the same time, a small amount of water in the slow-release chamber 4 enters the storage chamber 3 through the gap between the slow-release control valve 7 and the wall of the channel 61, replenishing the water in the storage chamber 3 to dissolve the solid cleaning agent 300.

[0102] In one embodiment, if Figure 2-6 and Figure 10-11 As shown, the slow-release control valve 7 is slidably assembled in the channel 61 , and the slow-release control valve 7 is connected to the slow-release chamber bottom 41 of the slow-release chamber 4 .

[0103] The slow-release cavity bottom 41 can change the volume of the slow-release cavity 4 by deformation or sliding.

[0104] The slow-release chamber bottom 41 and / or the slow-release control valve 7 are connected with an elastic reset member 9 capable of driving the slow-release chamber bottom 41 and / or the slow-release control valve 7 to reset.

[0105] In this embodiment, the slow-release control valve 7 can be raised and lowered in the channel 61 to achieve switching between a closed state and an open state.

[0106] When the slow-release control valve 7 is in a closed state, the slow-release control valve 7 is in a high position in the passage 61 , or a portion of the slow-release control valve 7 extends into the storage chamber 3 .

[0107] When the slow-release control valve 7 is in an open state, the slow-release control valve 7 is in a low position in the passage 61 , or a portion of the slow-release control valve 7 extends into the slow-release chamber 4 .

[0108] The lower end of the slow-release control valve 7 is connected to the slow-release chamber bottom 41 of the slow-release chamber 4, and the two move together.

[0109] The slow-release chamber bottom 41 can be deformed or slid to change the volume of the slow-release chamber 4. When the volume of the slow-release chamber 4 is reduced to a certain extent, the slow-release control valve 7 is in a closed state. When the volume of the slow-release chamber 4 is increased to a certain extent, the slow-release control valve 7 is in an open state.

[0110] The sustained-release chamber bottom 41 has the following two configurations:

[0111] The first method: the slow-release chamber bottom 41 can slide relative to the lower shell 2 or the spacer 6 to change the volume of the slow-release chamber 4. In this method, the slow-release chamber bottom 41 adopts a slide plate or a piston, which is slidably and sealedly connected to the lower shell 2.

[0112] The second method: the slow-release chamber bottom 41 of the slow-release chamber 4 can be deformed relative to the lower shell 2 or the spacer 6 to change the volume of the slow-release chamber 4. In this method, the slow-release chamber bottom 41 adopts an elastic diaphragm or other elastic sealing member, which is fixedly connected to the lower shell 2.

[0113] The elastic reset member 9 can be selectively connected to the slow-release chamber bottom 41 and / or the slow-release control valve 7 to help reset the slow-release chamber bottom 41 and / or the slow-release control valve 7. The elastic reset member 9 can be a spring or an elastic sheet.

[0114] Specifically, when the water control valve 400 is opened, water is injected into the slow-release chamber 4, and the water pressure overcomes the force of the elastic reset member 9, driving the slow-release chamber bottom 41 to move downward, thereby increasing the volume of the slow-release chamber 4, and the slow-release control valve 7 is converted from the closed state to the open state. After the water control valve 400 is closed, under the action of the elastic reset member 9, the slow-release chamber bottom 41 moves upward, thereby reducing the volume of the slow-release chamber 4, and the detergent dilution solution in the slow-release chamber 4 is discharged, and the slow-release control valve 7 is converted from the open state to the closed state.

[0115] In one embodiment, if Figure 2-6 , Figure 9-11 and Fig.15 As shown, the bottom 41 of the slow-release chamber is a slide plate or an elastic membrane 411 , which is convenient for assembly to change the volume of the slow-release chamber 4 .

[0116] The slide plate is located below the discharge port 42, and is slidably connected to the lower shell 2, and a sealing ring is installed between the slide plate and the lower shell 2 for sealing. Preferably, when the slow-release control valve 7 is in a closed state, the top surface of the slide plate is adjacent to the lower edge of the discharge port 42 to minimize the volume of the slow-release chamber 4 and discharge the diluted detergent solution in the slow-release chamber 4 as much as possible.

[0117] The elastic diaphragm 411 is a rubber diaphragm or a silicone diaphragm, and its edge is directly fixedly connected to the lower shell 2, and the connection edge of the elastic diaphragm 411 is below the discharge port 42. Preferably, the connection edge of the elastic diaphragm 411 is adjacent to the lower edge of the discharge port 42, and the volume of the slow-release chamber 4 can be reduced to a minimum when resetting, and the diluted detergent solution in the slow-release chamber 4 can be discharged as much as possible.

[0118] In one embodiment, if Figure 4 As shown, one end of the discharge pipe 200 is connected to a tee 201 so as to be connected to the water outlet pipe 402 .

[0119] In one embodiment, if Figure 8 As shown, the housing of the detergent slow release device 100 is connected with a mounting bracket 10 for installation and fixation. The upper end of the mounting bracket 10 is connected to the upper housing 1, and the lower end thereof is connected to the lower housing 2.

[0120] In one embodiment, if Figure 2-6 and Figure 10-11 As shown, below the slow-release cavity 4 is a mounting cavity 5 , in which the elastic reset member 9 is mounted, and a breathing hole 22 is provided on the cavity wall of the mounting cavity 5 .

[0121] In this embodiment, a mounting cavity 5 is disposed in the lower shell 2 , and the mounting cavity 5 is located below the slow-release cavity 4 . Specifically, the mounting cavity 5 is located below the slow-release cavity bottom 41 .

[0122] The elastic reset member 9 is installed in the installation cavity 5. The cavity wall of the installation cavity 5 is the side wall of the lower shell 2. The side wall of the lower shell 2 is provided with a breathing hole 22. When the bottom 41 of the slow-release cavity is deformed or slides, the breathing hole 22 exchanges air with the outside to maintain the internal air pressure balance and ensure the normal movement of the bottom 41 of the slow-release cavity.

[0123] In one embodiment, if Figure 9-11 As shown, a guide column 23 is provided in the installation cavity 5 , and the slow-release control valve 7 is slidably connected to the guide column 23 .

[0124] In this embodiment, a guide column 23 extending upward is provided in the installation cavity 5, and the guide column 23 is provided at the center of the bottom cover 21. The slow-release control valve 7 is slidably connected to the guide column 23, and the guide column 23 provides guidance for the lifting movement of the slow-release control valve 7.

[0125] The elastic reset member 9 can be a spring, which is sleeved on the guide column 23. The lower end of the spring is connected to the bottom cover 21, and the upper end is connected to the slow-release control valve 7.

[0126] In one embodiment, if Figure 10-11 , Fig.17 and Fig.19 As shown, the slow-release control valve 7 has a guide hole 70 opening downward, and the guide column 23 is inserted into the guide hole 70 to facilitate the assembly of the guide column 23 and the slow-release control valve 7. The guide column 23 is loosely fitted in the guide hole 70, and the slow-release control valve 7 can slide up and down relative to the guide column 23.

[0127] In one embodiment, if Figure 10-11 , Fig.17 and Fig.19 As shown, the lower end of the slow-release control valve 7 is provided with an annular groove 712 for mounting the elastic return member 9 , so as to facilitate connecting the upper end of the elastic return member 9 with the lower end of the slow-release control valve 7 .

[0128] Specifically, the annular groove 712 is provided on the bottom surface of the valve seat 71 of the slow-release control valve 7 .

[0129] In one embodiment, if Figure 2-6 and Figure 10-11 As shown, the slow-release control valve 7 includes an accommodating groove 73 for carrying the cleaning agent from the storage chamber 3 and / or the channel 61 to the slow-release chamber 4 .

[0130] When the slow-release control valve 7 is in a closed state, the channel 61 and the slow-release chamber 4 are in a disconnected state, and the accommodating groove 73 is in communication with the storage chamber 3 and / or the channel 61 .

[0131] When the slow-release control valve 7 is in an open state, the channel 61 is in a communicating state with the slow-release chamber 4 , and the accommodating groove 73 is in communication with the slow-release chamber 4 .

[0132] The slow-release control valve 7 can be raised and lowered as the volume of the slow-release chamber 4 changes, thereby driving the accommodating groove 73 to communicate with the storage chamber 3 / or the channel 61, and can also drive the accommodating groove 73 to communicate with the slow-release chamber 4.

[0133] In the normal state or initial state, the slow-release control valve 7 is closed, and the accommodating groove 73 is connected with the storage chamber 3 or the channel 61. In the normal state, if the channel 61 and the storage chamber 3 are disconnected or closed by the slow-release control valve 7, the accommodating groove 73 is at least partially in the storage chamber 3, and the detergent in the storage chamber 3 enters the accommodating groove 73. In the normal state, if the channel 61 is connected with the storage chamber 3, the accommodating groove 73 is in the channel 61, and the detergent in the channel 61 enters the accommodating groove 73.

[0134] After the slow-release chamber bottom 41 is deformed or slid to increase the volume of the slow-release chamber 4, the slow-release control valve 7 is lowered and opened, the accommodating groove 73 is communicated with the slow-release chamber 4, and the detergent carried by the accommodating groove 73 enters the slow-release chamber 4 and mixes with the water in the slow-release chamber 4 to form a detergent dilution solution. Preferably, when the accommodating groove 73 is communicated with the slow-release chamber 4, the accommodating groove 73 is at least partially in the slow-release chamber 4.

[0135] In this embodiment, the slow-release control valve 7 provided with the accommodating groove 73 is similar to an elevator, carrying a fixed amount of cleaning agent into the slow-release chamber 4 each time.

[0136] In this embodiment, the slow-release control valve 7 adopts a purely mechanical structure and does not need to be electrically driven, thereby reducing costs.

[0137] In one embodiment, if Figure 2-6 , Figure 9-11 and Figure 16-19 As shown, the slow-release control valve 7 includes a valve seat 71 and a valve body 72 connected to the valve seat 71 .

[0138] The accommodating groove 73 is provided on the side of the valve body 72. The slow-release chamber bottom 41 of the slow-release chamber 4 is connected to the valve seat 71 and / or the valve body 72. The valve body 72 is installed in the channel 61. A sealing ring 8 is provided on the wall of the valve body 72 and / or the channel 61.

[0139] In this embodiment, the slow-release control valve 7 includes a valve seat 71 and a valve body 72, the valve body 72 is connected to the valve seat 71, and the accommodating groove 73 is provided on the circumferential surface of the valve body 72. As needed, a plurality of accommodating grooves 73 can be provided on the side of the valve body 72 to increase the amount of detergent carried at a single time.

[0140] like Figure 3 As shown, the valve body 72 is integrally connected with the valve seat 71, and the guide hole 70 is provided in the valve seat 71 and the valve body 72. The valve seat 71 is divided into an upper valve seat and a lower valve seat, and the slow-release chamber bottom 41 is sandwiched between the upper valve seat and the lower valve seat.

[0141] like Figure 18-19 As shown, the valve body 72 is detachably connected to the valve seat 71. The guide hole 70 is provided in the valve seat 71 and the valve body 72. Specifically, the valve body 72 is provided with a connecting sleeve 711, the connecting sleeve 711 is provided with an external thread, the lower section of the guide hole 70 of the valve body 72 has an internal thread, the connecting sleeve 711 is threadedly connected to the guide hole 70 of the valve body 72, and the slow-release chamber bottom 41 is clamped between the valve body 72 and the valve seat 71. The connecting sleeve 711 also passes through the positioning hole of the slow-release chamber bottom 41, and the connection is more stable.

[0142] During assembly, the valve body 72 passes through the channel 61 or is installed in the channel 61 and is sealed by the sealing ring 8. The sealing ring 8 can be installed on the wall surface of the channel 61 or on the circumferential surface of the valve body 72.

[0143] When the slow-release control valve 7 is in a closed state, the valve body 72 is in a raised position (high position) in the channel 61, the accommodating groove 73 is above the sealing ring 8, the entire accommodating groove 73 is in the channel 61 or at least part of the accommodating groove 73 is in the storage chamber 3, and the cleaning agent will enter the accommodating groove 73.

[0144] When the slow-release control valve 7 is in the open state, the valve body 72 is in a lowered position (low position) in the channel 61, the accommodating groove 73 descends to the bottom of the sealing ring 8 or the sealing ring 8 leaves the channel lower port 611 of the channel 61, and the accommodating groove 73 is connected to the slow-release chamber 4, or the accommodating groove 73 is at least partially in the slow-release chamber 4, and the cleaning agent carried by the accommodating groove 73 enters the slow-release chamber 4.

[0145] In one embodiment, if Figure 2-6 As shown, the sealing ring 8 is arranged on the wall surface of the channel 61.

[0146] When the slow-release control valve 7 is in a closed state, the accommodating groove 73 is located above the sealing ring 8 and is communicated with the storage chamber 3 and / or the channel 61 .

[0147] When the slow-release control valve 7 is in an open state, the accommodating groove 73 is located below the sealing ring 8 and communicates with the slow-release chamber 4 .

[0148] In this embodiment, the sealing ring 8 is fixedly mounted on the wall surface of the channel 61, and a groove may be provided on the wall surface of the channel 61 for mounting the sealing ring 8. The valve body 72 moves up and down relative to the sealing ring 8.

[0149] When the slow-release control valve 7 is in a closed state, the valve body 72 moves up to the initial position, and the accommodating grooves 73 are all above the sealing ring 8. The accommodating grooves 73 can be in the storage chamber 3 or in the channel 61. The detergent in the storage chamber 3 or in the channel 61 will enter the accommodating grooves 73 for storage.

[0150] When the slow-release control valve 7 is in the open state, the valve body 72 moves down to the open position, at least part of the accommodating groove 73 is located below the sealing ring 8 , which is connected to the slow-release chamber 4 , and the detergent enters the slow-release chamber 4 .

[0151] In this embodiment, due to the sealing effect of the sealing ring 8, the water in the slow-release chamber 4 will basically not enter the storage chamber 3 through the channel 61. The storage chamber 3 preferably uses a liquid detergent that will not be diluted by the water in the slow-release chamber 4. The liquid detergent discharged from the storage chamber 3 each time is also basically quantitative.

[0152] In one embodiment, if Figure 2-6 As shown, the valve body 72 passes through the passage 61 .

[0153] When the slow-release control valve 7 is in a closed state, the accommodating groove 73 is at least partially located in the storage chamber 3 .

[0154] When the slow-release control valve 7 is in an open state, the accommodating groove 73 is at least partially located in the slow-release chamber 4 .

[0155] In this embodiment, the length of the valve body 72 is greater than the length of the channel 61. When the slow-release control valve 7 is in a closed state, the upper end of the valve body 72 extends into the storage chamber 3 and brings at least part of the accommodating groove 73 into the storage chamber 3 to accommodate the detergent. Preferably, the entire accommodating groove 73 enters the storage chamber 3.

[0156] When the slow-release control valve 7 is in an open state, the lower end of the valve body 72 extends into the slow-release chamber 4, and brings at least part of the accommodating groove 73 into the slow-release chamber 4 to directly release the detergent into the slow-release chamber 4. Preferably, the entire accommodating groove 73 enters the slow-release chamber 4.

[0157] In one embodiment, if Figure 10-11 As shown, the sealing ring 8 is arranged at the lower end of the valve body 72 , and the accommodating groove 73 is located above the sealing ring 8 .

[0158] When the slow-release control valve 7 is in the closed state, the sealing ring 8 closes the channel lower port 611 of the channel 61 .

[0159] When the slow-release control valve 7 is in the open state, the sealing ring 8 moves downward away from the lower channel port 611 .

[0160] In this embodiment, the sealing ring 8 is arranged on the circumferential surface of the lower end of the valve body 72. Specifically, an assembly groove 723 is provided on the circumferential surface of the lower end of the valve body 72. The sealing ring 8 is assembled in the assembly groove 723 to seal the lower channel port 611 of the channel 61.

[0161] When the slow-release control valve 7 is in a closed state, the valve body 72 moves up to the initial position, the sealing ring 8 closes the lower channel port 611, the accommodating groove 73 is in the channel 61, and the upper channel port of the channel 61 is connected to the storage chamber 3, and the detergent will flow into the channel 61 and enter the accommodating groove 73.

[0162] When the slow-release control valve 7 is in the open state, the valve body 72 moves downward and drives the sealing ring 8 downward to leave the lower channel port 611, the accommodating groove 73 is connected with the slow-release chamber 4, or at least part of the accommodating groove 73 enters the slow-release chamber 4, and the detergent in the accommodating groove 73 flows into the slow-release chamber 4. At the same time, due to the high water pressure in the slow-release chamber 4, a small amount of water in the slow-release chamber 4 will flow into the storage chamber 3 through the gap between the wall surface of the channel 61 and the valve body 72, which plays a role in replenishing water on the one hand, and prevents the detergent in the storage chamber 3 from directly flowing into the slow-release chamber 4 through the channel 61 on the other hand.

[0163] In this embodiment, the storage chamber 3 preferably uses a solid detergent 300. The sealing ring 8 is used to open and close the lower channel port 611. When the slow-release control valve 7 is opened, a small amount of water in the slow-release chamber 4 will enter the storage chamber 3 through the channel 61 to play the role of replenishing water, thereby preventing the storage chamber 3 from lacking water and being unable to dissolve the solid detergent 300. The amount of replenished water is controlled by the water pressure in the slow-release chamber 4 and the gap between the wall of the channel 61 and the valve body 72.

[0164] In one embodiment, if Figure 10-12 and Fig.14 As shown, a cap 62 is disposed at the upper end of the channel 61, and a cap opening 621 communicating with the channel 61 is disposed at the top and / or side of the cap 62. The valve body 72 is located below the cap 62.

[0165] In this embodiment, a cap 62 is disposed at the upper end of the channel 61, and the cap 62 is located in the storage chamber 3 to cover the upper end of the channel. The top and / or side of the cap 62 is provided with a cap opening 621 connected to the channel 61, for the detergent to flow downward, and for the supplemented water to enter the storage chamber 3.

[0166] In this embodiment, by configuring a cap 62 with a cap opening 621, the flow rate of the detergent into the channel 61 can be limited. When the slow-release control valve 7 is opened, a small amount of water in the slow-release chamber 4 can smoothly break through the resistance of the detergent in the flow channel 61, and then flush part of the detergent back into the storage chamber 3, thereby reducing the loss or waste of the detergent.

[0167] The small amount of water involved in the present invention is not quantitative, it is only compared with the remaining large amount of water.

[0168] In one embodiment, if Figure 10-12 and Fig.19 As shown, a plug 721 is provided at the upper end of the valve body 72 , and a flow gap is formed between the plug 721 and the wall surface of the channel 61 .

[0169] In this embodiment, a plug 721 is provided at the upper end of the valve body 72 to reduce the gap between the valve body 72 and the wall surface of the channel 61, thereby controlling the flow of the cleaning liquid. When the slow-release control valve 7 is in a closed state, the plug 721 enters the cap 62 and contacts the top plate of the cap 62, and the cap 62 blocks the valve body 72 from continuing to move upward, thereby playing a limiting role.

[0170] In one embodiment, if Figure 10-11 As shown, the slow-release chamber bottom 41 is sandwiched between the valve seat 71 and the valve body 72 .

[0171] In this embodiment, a connecting sleeve 711 is provided on the valve body 72, and an external thread is provided on the connecting sleeve 711. The lower section of the guide hole 70 of the valve body 72 has an internal thread. The connecting sleeve 711 is threadedly connected to the guide hole 70 of the valve body 72. The connecting sleeve 711 also passes through the positioning hole of the bottom 41 of the slow-release chamber. The bottom 41 of the slow-release chamber is clamped between the valve body 72 and the valve seat 71, and the connection is more stable.

[0172] In one embodiment, if Figure 18-19 As shown, the top surface of the valve seat 71 and the bottom surface of the valve body 72 are respectively provided with a protrusion 74 for pressing against the bottom 41 of the slow-release chamber.

[0173] The protrusion 74 can be a protruding ring provided on the top surface of the valve seat 71 and the bottom surface of the valve body 72, and is used to clamp the slow-release chamber bottom 41. The protrusion 74 is preferably a rubber protrusion, which has elasticity and can reduce the wear on the slow-release chamber bottom 41.

[0174] Preferably, a plurality of protrusions 74 are respectively provided on the top surface of the valve seat 71 and the bottom surface of the valve body 72 , and the protrusions 74 on the top surface of the valve seat 71 and the protrusions 74 on the bottom surface of the valve body 72 are arranged alternately to bite the slow-release cavity bottom 41 .

[0175] In one embodiment, if Figure 3 and Fig.16 As shown, the accommodating groove 73 is one or more arc-shaped grooves provided on the circumferential surface of the valve body 72. Alternatively, the accommodating groove 73 is one or more annular grooves provided on the circumferential surface of the valve body 72.

[0176] In this embodiment, the accommodating groove 73 can be an arc-shaped groove or an annular groove. A plurality of annular grooves and / or arc-shaped grooves can be arranged at intervals up and down on the circumferential surface of the valve body 72, or a plurality of arc-shaped grooves can be arranged at intervals along the circumferential direction on the circumferential surface of the valve body 72 to increase the capacity of the cleaning agent carried at a single time.

[0177] In one embodiment, if Figure 16-19 As shown, a plurality of partition ribs 722 are provided at intervals on the circumferential surface of the valve body 72, and the partition ribs 722 extend along the axial direction of the valve body 72. A plurality of accommodating grooves 73 are provided between any two adjacent partition ribs 722.

[0178] In this embodiment, the accommodating groove 73 is an arc-shaped groove, and a plurality of partition ribs 722 extending along the circumferential direction are arranged at intervals on the circumferential surface of the valve body 72, and a plurality of accommodating grooves 73 are arranged between every two partition ribs 722. The partition ribs 722 protrude from the notches of the accommodating grooves 73, which can reduce the mutual influence between adjacent accommodating grooves 73 in the circumferential direction.

[0179] Preferably, the receiving groove 73 is located deep within the two partition ribs 722. Assuming that the radial length of the partition rib 722 is D, the distance between the notch of the receiving groove 73 and the outer peripheral surface of the partition rib 722 is greater than or equal to D / 2. With such an arrangement, when the slow-release control valve 7 is opened, a small amount of water in the slow-release chamber 4 will enter the channel 61, and the partition rib 722 acts to block or slow down the water from entering the receiving groove 73, so as to reduce the amount of detergent carried away by the water, thereby ensuring that a large amount of detergent in the receiving groove 73 will not be carried away by the water, so that it can flow into the slow-release chamber 4.

[0180] like Fig. 20 As shown, a water-using device provided by one embodiment of the present invention includes a water-using device 500, a water-using control valve 400 and the detergent slow-release device described in any of the aforementioned embodiments.

[0181] The water outlet pipe 402 of the water control valve 400 is connected to the water device 500 , and the drainage pipe 200 is connected to the water outlet pipe 402 .

[0182] When the water control valve 400 is in the open state, the discharge pipe 200 is in the state of injecting water into the slow-release chamber 4, most of the water in the outlet pipe 402 is supplied to the water device 500, and a small amount of water in the outlet pipe 402 is injected into the slow-release chamber 4 through the discharge pipe 200.

[0183] When the water control valve 400 is in a closed state, the water outlet pipe 402 is in a water-stopped state, the discharge pipe 200 is in a state of discharging liquid to the water outlet pipe 402, and the diluted detergent solution in the slow-release chamber 4 is supplied from the water outlet pipe 402 to the water device 500 for cleaning.

[0184] The water-using equipment provided by the present invention is a toilet equipment, a urinal equipment, a basin equipment, a shower equipment, etc. used in kitchens, bathrooms or public places.

[0185] The water-using equipment includes a water-using control valve 400, a water-using device 500 and the aforementioned detergent slow-release device. For the structure, construction and working principle of the detergent slow-release device, please refer to the above description of the detergent slow-release device, which will not be repeated here.

[0186] The water inlet pipe 401 of the water control valve 400 is connected to the water supply pipe of the building. The water-using device 500 is a water-using terminal of water-using equipment, such as a toilet, a urinal, a shower, a sink, a basin, and the like.

[0187] The water outlet pipe 402 of the water control valve 400 is connected to the water device 500. The water control valve 400 can be a mechanical valve or an automatic sensing valve.

[0188] One end of the discharge pipe 200 is connected to the water outlet pipe 402 , and specifically can be connected to the water outlet pipe 402 via a tee 201 .

[0189] The water control valve 400 is normally in a closed state. When the water device 500 needs water, the water control valve 400 is opened, the discharge pipe 200 starts to inject water into the slow-release chamber 4, most of the water in the outlet pipe 402 is supplied to the water device 500, and a small part of the water in the outlet pipe 402 is injected into the slow-release chamber 4 through the discharge pipe 200. The volume of the slow-release chamber 4 gradually increases, and the slow-release control valve 7 opens as the volume of the slow-release chamber 4 increases, and part of the detergent in the storage chamber 3 enters the slow-release chamber 4, and then mixes with the water entering the slow-release chamber 4 to form a detergent dilution solution.

[0190] After the user has finished using the water device 500, the water control valve 400 is closed, and the water outlet pipe 402 stops supplying water to the water device 500. At this time, the water pressure in the slow-release chamber 4 is greater than the water pressure in the water outlet pipe 402, and the injection pipe 200 is in a state of discharging liquid to the water outlet pipe 402. During this process, the volume of the slow-release chamber 4 gradually decreases until it is reset to the initial state, and the slow-release control valve 7 returns to the closed state. When the injection pipe 200 is in a state of discharging liquid to the water outlet pipe 402, the diluted detergent solution in the slow-release chamber 4 is supplied to the water device 500 through the injection pipe 200 and the water outlet pipe 402 for self-cleaning of the water device 500.

[0191] The water-using equipment provided by the present invention has a detergent slow-release device that only provides detergent at the end of the water use of the water-using device 500, that is, it starts to provide detergent after the water control valve 400 is closed. During the process of the user using the water-using device 500, no detergent is discharged, and it will not affect the user's normal use of showers, washbasins, etc. Therefore, it can be used for toilets and urinals, as well as showers and basins, expanding the scope of application.

[0192] In the water-using equipment provided by the present invention, since the detergent slow-release device only provides detergent at the end of the water-using device 500, no detergent will be discharged at the beginning of the water-using device 500, thereby effectively avoiding the waste of detergent.

[0193] The water-using equipment provided by the present invention has a detergent slow-release device that only provides detergent at the water-using end of the water-using device 500. Therefore, before the user uses the water-using device 500 next time, no water will flush the detergent away from the water-using device 500. The detergent stays on the water-using device 500 for a long time, which can better dissolve scale, stains, etc. When the water-using device 500 is used next time, water will quickly and smoothly drain away the dissolved dirt on the water-using device 500, thereby improving the cleaning effect.

[0194] In one embodiment, if Figure 7 As shown, the water-using device 500 includes a basin, a shower, a toilet or a urinal 501, etc., and has a wide range of applications.

[0195] When applied to a toilet, the water control valve 400 can be a drain valve of the toilet, and the water outlet pipe 402 can be a flushing pipe connected between the drain valve and the ceramic body of the toilet. After the water tank is drained, the detergent slow-release device starts to discharge a certain amount of detergent into the ceramic body of the toilet, and the detergent is discharged through the flushing pipe of the toilet. The detergent dissolves the dirt on the ceramic body. When the water tank is drained next time, the dissolved substances on the ceramic body can be flushed away smoothly, and the cleaning effect is good.

[0196] When applied to a urinal, the water control valve 400 can be a control valve around the urinal 501. Generally, an automatic sensing valve is selected. After the user has used the urinal and a single flushing is about to be completed, the detergent slow-release device starts to discharge a certain amount of detergent into the ceramic body of the urinal. The detergent is discharged through the nozzle of the urinal. The detergent dissolves the dirt on the ceramic body. When the outlet pipe 402 drains water next time, the dissolved substances on the ceramic body can be flushed away smoothly, and the cleaning effect is good.

[0197] When applied to a basin or sink, the water control valve 400 can be the faucet water valve of the basin or sink, and the water outlet pipe 402 can be a water pipe connected between the faucet water valve and the faucet nozzle. After the user has used the basin or sink, the faucet water valve is closed, and the detergent slow-release device begins to discharge a certain amount of detergent into the basin or sink, and the detergent is discharged through the faucet nozzle. Of course, a special nozzle can also be set to expand the spraying area. The detergent dissolves the dirt on the basin or sink. When the user uses the basin or sink next time, the water can smoothly drain the dissolved substances on the basin or sink, and the cleaning effect is good. When applied to a basin or sink, a detergent that meets the hygiene and safety standards can be selected, for example, a food detergent. The user can also pre-rinse the basin or sink when using it next time. Because the basin or sink will be cleaned after each use, the dosage of the detergent discharged each time can be set to a very small dosage, and the pre-rinsing time is very short.

[0198] When applied to a shower, the water control valve 400 can be a shower valve, and the water outlet pipe 402 can be a water pipe connected between the shower valve and the shower head. According to actual needs, the discharge pipe 200 of the detergent slow-release device can be connected to a place close to the shower head so that the detergent can be smoothly discharged into the shower head. After the user uses the shower, the shower valve is closed, and the detergent slow-release device starts to discharge a fixed amount of detergent. The detergent dissolves stains, scale, etc. in the water pipe and the shower head. When the user uses the shower next time, the water can smoothly discharge the dissolved substances in the water pipe and the shower head, and the cleaning effect is good.

[0199] As needed, the above technical solutions can be combined to achieve the best technical effect.

[0200] The above are only the principles and preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several other modifications can be made based on the principles of the present invention, which should also be considered as the protection scope of the present invention.
