Description

TECHNICAL FIELD

[0001] The present application relates to the field of bathroom technology, in particular to a cleaning agent automatic adder and a bathroom device. BACKGROUND

[0002] After use, the bathroom tool needs to be flushed to keep clean and sanitary. In order to obtain better cleaning effect, cleaning agent is usually added to the flushing water. Most of the currently used cleaning agents are solid, which are put into the water tank to release cleaning components by slow dissolution in water. If the time interval between two consecutive flushes is short, the concentration of cleaning agent in water is too low to effectively flush the bathroom. If the time interval between two consecutive flushes is long, the concentration of cleaning agent in water is too high to effectively flush the bathroom, but it wastes cleaning agent. Therefore, the solid cleaning agent cannot achieve the problem of timed and quantitative addition of cleaning agent to water.

[0003] Therefore, the invention patent application with application number 202210309128.0 discloses a water power automatic adding device, which includes a bottle for containing water agent and a feeding pipe connected with the bottle. Three spherical valve cores connected by connecting rods in the feeding pipe constitute three one-way valves arranged from top to bottom. The valve core located at the pipe opening of the feeding pipe is a floating ball. In use, the feeding pipe is downward, supported by the shell connected at the bottom of the water tank. The floating ball floats up and down to control the opening and closing state of the three one-way valves to add the water agent in the bottle to the water according to the water level change of the water tank. The inventor found that this device has the following problems in use:

[0004] 1. If the three one-way valves are in the conducting state at the same time, and the water level does not change or rises too slowly, the three one-way valves will be in the conducting state for a long time and cannot be closed, which will cause the water agent to be completely leaked or the water agent to be added too much, and the water agent addition amount cannot be accurately controlled.

[0005] 2. The bottle and the feeding pipe need to be sleeved with a shell as a support to be placed in the water tank or other water tank for use. It is not very convenient to take and place, and it has certain requirements for the bottom space of the water tank or the water tank. SUMMARY

[0006] One of the purposes of the present application is to design a cleaning agent automatic adder and a bathroom device to solve the problem that the existing cleaning agent adder cannot accurately add cleaning agent.

[0007] The present application is achieved by the following technical solutions:

[0008] The present application provides a kind of automatic cleaner adding device, including container, piston, first one-way valve, second one-way valve and linkage rod;The container can be straightly floated on water surface, and its inside has storage cavity and quantitative cavity arranged from top to bottom and communicated;The piston is arranged in the quantitative cavity, the piston is dynamically sealed with the wall of the quantitative cavity and can move up and down;The first one-way valve is connected with the piston to move with the piston, and the first one-way valve is one-way communicated from the storage cavity to the quantitative cavity;The second one-way valve is arranged below the first one-way valve, and the second one-way valve is one-way communicated from the quantitative cavity to the outside of the quantitative cavity;The linkage rod is vertically arranged and connected with the piston by penetrating into the quantitative cavity from the outside of the container, wherein the piston can move up and down with the linkage rod, and the first one-way valve can be opened by the negative pressure generated by the space between the first one-way valve and the second one-way valve when the piston moves upward.

[0009] When the above structure is adopted, the first one-way valve and the second one-way valve, which have the same opening direction, are arranged in the quantitative cavity of the container from top to bottom, which separates the quantitative cavity from the storage cavity and the outside, at the same time, the first one-way valve is installed on the piston and moves up and down with the piston, and the extended linkage rod can control the movement of the piston by using the bottom wall or top wall of the water tank or sink when the container moves with the water level. In this way, when the piston moves upward, the first one-way valve can be opened by the negative pressure generated by the enlarged space in front, which connects the quantitative cavity with the storage cavity, and allows the cleaner in the storage cavity to supplement the quantitative cavity. During this process, the second one-way valve can be closed all the time when the piston moves upward, which will not leak the cleaner in the quantitative cavity, and will not allow water to enter and contaminate the cleaner. When the piston moves downward, the first one-way valve will be quickly closed under pressure and push the cleaner in the quantitative cavity to the second one-way valve together with the piston, and the second one-way valve will be opened by the pushing action of the forced downward cleaner, which connects the quantitative cavity with the outside, allowing the cleaner in the quantitative cavity to be discharged. During this process, the first one-way valve can be closed all the time by the counterforce of the cleaner when the piston moves downward, which will not add cleaner to the quantitative cavity. Then the upward piston will also make the second one-way valve quickly close by the negative pressure generated above the second one-way valve. Therefore, the two processes of supplementing and discharging cleaner of the automatic cleaner adding device are independent and do not affect each other, which can accurately quantify the discharge of cleaner and effectively avoid the contamination of cleaner by water entering the inside of the quantitative cavity. In addition, the floating container can make the automatic cleaner adding device float on the water surface, which can be easily taken and placed, and has less impact on the installation space of the water tank or sink.

[0010] Further, in order to better achieve the present application, the following structure is particularly adopted: the automatic cleaner adding device further comprises a cover, which is detachably connected to the container to cover the opening of the storage cavity.

[0011] Further, in order to better realize the present application, the cover is provided with a vent hole for connecting the storage cavity with the outside.

[0012] Further, in order to better realize the present application, the cleaning agent automatic adder further comprises a spring connected with the piston for driving the piston to reset upward.

[0013] Further, in order to better realize the present application, the first one-way valve comprises a flexible first valve sheet, the piston is provided with a suction hole penetrating upward and downward, and the first valve sheet is installed at the bottom of the piston and seals the bottom end of the suction hole.

[0014] Further, in order to better realize the present application, the linking rod penetrates into the quantitative cavity upward and can pull the piston downward.

[0015] When the above structure is adopted, the part of the linking rod outside the container extends downward, the cleaning agent in the storage cavity can be supplemented into the quantitative cavity by the action of the linking rod touching the bottom when the water level drops, and the cleaning agent can be put into the water by the action of the linking rod moving downward due to gravity when the water level rises, so as to achieve the effect of putting the cleaning agent when the water is full and preparing the cleaning agent when the water is insufficient.

[0016] Further, in order to better realize the present application, the middle segment of the linking rod outside the container is provided with a piston limiting block, the second one-way valve is provided with a through hole, the linking rod is movably arranged in the through hole of the second one-way valve, and the diameter of the piston limiting block is greater than that of the through hole of the second one-way valve.

[0017] Further, in order to better realize the present application, the linking rod is provided with a sinker, and the sinker is located outside the container.

[0018] Further, in order to better realize the present application, the linking rod can also penetrate into the quantitative cavity downward.

[0019] When the above structure is adopted, the part of the linking rod outside the container extends upward, the cleaning agent in the quantitative cavity can be put into the water by the action of the linking rod touching the top when the water level rises, and the cleaning agent in the storage cavity can be supplemented into the quantitative cavity by the action of the linking rod moving upward due to the spring when the water level drops, so as to achieve the effect of putting the cleaning agent when the water is full and preparing the cleaning agent when the water is insufficient.

[0020] The present application also provides a bathroom device comprising the cleaning agent automatic adder.

[0021] The present application has the following advantages and beneficial effects:

[0022] In the present application, the first one-way valve and the second one-way valve with the same conduction direction are arranged in the dosing cavity of the container in sequence from top to bottom, which separates the dosing cavity from the storage cavity and the outside world respectively. Meanwhile, the first one-way valve is installed on the piston and moves up and down with the piston. The extended connecting rod can control the movement of the piston by using the bottom wall or the top wall of the water tank or the sink when the container moves with the water level. In this way, when the piston moves upward, the first one-way valve can be opened due to the negative pressure generated by the enlarged front space, which connects the dosing cavity with the storage cavity, and allows the cleaning agent in the storage cavity to supplement the dosing cavity. During this process, the second one-way valve can be closed throughout the upward movement of the piston, so that the cleaning agent in the dosing cavity cannot leak out, and water cannot enter to contaminate the cleaning agent. When the piston moves downward, the first one-way valve will be quickly closed under pressure and push the cleaning agent in the dosing cavity to the second one-way valve together with the piston. The second one-way valve will be opened by the pushing action of the forced downward cleaning agent, which connects the dosing cavity with the outside world, allowing the cleaning agent in the dosing cavity to be discharged. During this process, the first one-way valve can be closed throughout the downward movement of the piston due to the counter-thrust of the cleaning agent, so that no cleaning agent is added to the dosing cavity. Then, the upward piston will also make the second one-way valve quickly close by the negative pressure generated above the second one-way valve. Therefore, the two processes of supplementing and discharging the cleaning agent of the cleaning agent automatic feeder are independent and do not affect each other, which can accurately dose the cleaning agent and effectively prevent water from entering the dosing cavity to contaminate the cleaning agent. In addition, the floating container can make the cleaning agent automatic feeder float on the water surface, which is convenient to take and place, and has less impact on the installation space of the water tank or the sink.

[0047] Embodiment 1:

[0048] An automatic detergent dispenser can accurately dispense cleaning agents, such as Figures 1-3 , Figures 6-10 As shown in the drawings, it is specially designed as follows:

[0049] In this embodiment, the automatic detergent dispenser is a bottom-touch dispensing type.

[0050] Specifically, the automatic detergent dispenser comprises a container 7, a piston 3, a first one-way valve, a second one-way valve and a connecting rod 6.

[0051] As shown in Figures 1-3 , and Figure 6 The container 7 is a top-opened rotary body structure, and a storage cavity 72 and a quantitative cavity 73 vertically aligned from top to bottom and communicating are formed inside the container 7, and the quantitative cavity 73 is in communication with the outside. The storage cavity 72 and the quantitative cavity 73 are both used for storing cleaning agents, and the inner diameter of the storage cavity 72 is larger than that of the quantitative cavity 73. When the container 7 is placed in water with the open top upwards, it can stand upright and float on the water surface, so that the automatic detergent dispenser as a whole can float on the water surface in a stable upright posture.

[0052] As shown in Figure 2 , the piston 3 is arranged in the quantitative cavity 73 and coaxially arranged with the axis of the quantitative cavity 73, and the peripheral wall of the piston 3 is dynamically sealed with the peripheral wall of the quantitative cavity 73 by a sealing ring. Specifically, as shown in Figure 10As shown, the peripheral wall of the piston 3 is provided with a sealing groove 34, and a small sealing ring 4 is installed in the sealing groove 34, and the piston 3 is in dynamic sealing cooperation with the peripheral wall of the metering cavity 73 through the small sealing ring 4. The piston 3 can be moved upward or downward along the axis of the metering cavity 73 under the action of an external force, and the moving direction depends on the action direction of the external force.

[0053] The first one-way valve and the second one-way valve are arranged at the metering cavity 73 to control the conduction state of the storage cavity 72 and the metering cavity 73. The first one-way valve is integrally installed on the piston 3 and can move synchronously with the piston 3, and the second one-way valve is arranged below the first one-way valve and is relatively fixed to the metering cavity 73 and cannot move upward or downward along the axis of the metering cavity 73. The conduction directions of the first one-way valve and the second one-way valve are consistent, so that the cleaning agent in the storage cavity 72 needs to pass through the first one-way valve and the second one-way valve in sequence and then pass through the metering cavity 73 to reach the outside of the container 7. Specifically, the first one-way valve is unidirectional from the storage cavity 72 to the metering cavity 73, and the second one-way valve is unidirectional from the metering cavity 73 to the outside of the metering cavity 73. As known from the above, the first one-way valve can be affected by the negative pressure generated by the space between the first one-way valve and the second one-way valve when the piston 3 moves upward.

[0054] Specifically, as shown in Figure 2 , Figure 9 and Figure 10 , the peripheral wall of the piston 3 is provided with a sealing groove 34, and the two end faces are concave to form a circular valve plate mounting groove 35, and a center hole is arranged at the center position of the groove bottom of the valve plate mounting groove 35, and at the same time, a plurality of upward through suction holes 33 are arranged at the position outside the center hole on the groove bottom of the valve plate mounting groove 35, of course, the suction hole 33 can also be one. The first one-way valve includes a flexible first valve plate 8a, which is installed by the structure of the piston 3 to realize the ability of one-way conduction. The first valve plate 8a includes a plate body 83 and a fixed column 81 connected to the back of the plate body 83, and a clamping position 82 is arranged at the end of the fixed column 81. The plate body 83 of the first valve plate 8a is accommodated in the valve plate mounting groove 35 at the bottom of the piston 3 and seals the suction hole 33, the fixed column 81 is inserted into the center hole of the piston 3, the clamping position 82 passes through the center hole of the piston 3 to the other end and abuts against the piston 3 to prevent the first valve plate 8a from falling off.

[0055] As shown in Figure 2 and Figure 7As shown, the second one-way valve comprises a flexible second valve plate 8b which is installed with the valve seat arranged at the bottom end of the metering cavity 73 to realize the ability of one-way conduction. Specifically, the bottom end of the metering cavity 73 is provided with an end plate which serves as the valve seat of the second valve plate 8b, and the structure of the second valve plate 8b is the same as that of the first valve plate 8a and will not be described here. The bottom center of the valve seat is upwardly recessed to form a circular groove, and a center hole penetrating upward and downward is arranged at the center of the groove, and a shooting hole 71 penetrating upward and downward is also arranged at the side of the center hole. The fixing column of the second valve plate 8b is inserted into the center hole of the valve seat, and the clamping position passes through the center hole of the valve seat to the other end and abuts against the valve seat to prevent the second valve plate 8b from falling off.

[0056] As shown in Figures 1-3 , and Figure 8 , the link rod 6 is a straight rod part which is vertically arranged in the use state. The extended end of the link rod 6 is located at a position below the outside of the container 7, and the extended end of the link rod 6 is located in the metering cavity 73 and is fixedly connected with the piston 3, so that the link rod 6 passes through the second one-way valve in a vertically upward manner and enters the metering cavity 73 to be connected with the piston 3, so that the piston 3 can move up and down with the link rod 6.

[0057] Specifically, the center positions of the fixing columns of the first valve plate 8a and the second valve plate 8b are provided with through holes for the link rod 6 to pass through. The link rod 6 passes through the through holes of the second valve plate 8b in sequence and then passes through the through hole of the first valve plate 8a, and the top end of the link rod 6 is provided with a displacement limiting clamping block 63 with a diameter larger than the hole diameter of the through hole of the first valve plate 8a, and the displacement limiting clamping block 63 abuts against the top end of the fixing column 81 of the first valve plate 8a to avoid falling off from the first one-way valve.

[0058] The bottom end of the link rod 6 is provided with a pendant 9, and the shape of the pendant 9 is preferably spherical, and of course it can also be ellipsoidal or cubic, etc. The diameter of the pendant 9 is larger than the diameter of the link rod 6, and the pendant 9 can be integrally formed at the bottom end of the link rod 6 or assembled through relevant connecting structure, such as providing a pendant limiting clamping block 61 with a larger outer diameter than the rod segment at the bottom end of the link rod 6, and the pendant 9 is sleeved on the link rod 6 through the through hole radially arranged thereon, and the pendant limiting clamping block 61 is located at the bottom of the pendant 9 to hold it.

[0059] In the case that the link rod 6 is not configured with the pendant 9, the density of the link rod 6 is greater than the density of water, so that the link rod 6 can sink in water. When the link rod 6 is configured with the pendant 9, the density of the link rod 6 can be greater than or less than the density of water, but it is necessary to ensure that the density of the pendant 9 is greater than the density of water to improve the downward force of the link rod 6 on the piston 3, so that the link rod 6 can play the corresponding role and improve the sensitivity of the action.

[0060] In this embodiment, the first and second one-way valves with the same opening direction are arranged in the metering cavity 73 of the container 7 from top to bottom, which separates the metering cavity 73 from the storage cavity 72 and the outside environment, and the first one-way valve is installed on the piston 3 and moves up and down with the piston 3. The extended connecting rod 6 can control the movement of the piston 3 by using the bottom wall or top wall of the water tank or basin when the container 7 moves with the water level. When the piston 3 moves upward, the first one-way valve can be opened due to the negative pressure generated by the enlarged front space, which connects the metering cavity 73 with the storage cavity 72, and allows the cleaner in the storage cavity 72 to supplement the metering cavity 73. In this process, the second one-way valve can be closed throughout the upward movement of the piston 3, and the cleaner in the metering cavity 73 will not leak out, nor will the water contaminate the cleaner. When the piston 3 moves downward, the first one-way valve will be quickly closed under pressure and will push the cleaner in the metering cavity 73 to the second one-way valve together with the piston 3. The second one-way valve will be opened by the pushing action of the forced downward cleaner, which connects the metering cavity 73 with the outside environment, and allows the cleaner in the metering cavity 73 to be discharged. In this process, the first one-way valve can be closed throughout the downward movement of the piston 3 due to the counter-thrust of the cleaner, and will not add cleaner to the metering cavity 73. Then, the upward piston 3 will also make the second one-way valve quickly close by the negative pressure generated above the second one-way valve. Therefore, the two processes of supplementing and discharging the cleaner of this kind of automatic cleaner dispenser are independent and do not affect each other, which can accurately dose the cleaner and effectively prevent the water from contaminating the cleaner in the metering cavity 73. In addition, the floatable container 7 can make the automatic cleaner dispenser float on the water surface, which is convenient to take and place, and has less impact on the installation space of the water tank or basin.

[0061] As shown in Figures 1-3 , in order to cover the opening of the container 7, a cover 1 is provided for the container 7. The outer wall at the mouth of the container 7 is provided with two upper and lower sealing ring grooves, and each sealing ring groove is provided with a large sealing ring 2. The cover 1 is detachably connected with the container 7 by threads to cover the top opening of the storage cavity 72, and the large sealing ring 2 seals the connection between the cover 1 and the container 7. The center of the cover 1 is provided with a vent hole to communicate the storage cavity 72 with the outside environment, which facilitates the ventilation of the container 7 and helps the cleaner to flow out.

[0062] As shown in Figure 1 and Figure 2 , the cover can be a high cover with a certain depth groove inside. When the cover 1 is connected to the container 7, the inside of the cover 1 will form a cavity above the opening of the container 7, further reducing the overall density of the container 7, and allowing the automatic cleaner dispenser to stand more stably in the water.

[0063] As shown in Figures 1-3As shown, preferably, in order to improve the sensitivity of the piston 3's movement, the cleaning agent automatic dispenser is provided with a spring 5 in the metering chamber 73. The spring 5 is sleeved on the connecting rod 6, with its bottom end connected to the second check valve and its top end abutting against the bottom of the piston 3. The spring 5 can drive the piston 3 to return to its original position.

[0064] To limit the maximum upward extension of the spring 5 and prevent the piston 3 from being pushed into the storage cavity 72, a piston limiting block 62 with a diameter larger than the through hole diameter of the fixing post of the second valve plate 8b is provided on the middle section of the connecting rod 6 outside the container 7. The connecting rod 6 is movably inserted into the through hole of the fixing post of the second valve plate 8b. When the connecting rod 6 moves upward until the piston limiting block 62 abuts against the fixing post of the second valve plate 8b, the spring 5 is prevented from continuing to extend upward.

[0065] To limit the maximum downward movement of piston 3, a leak-proof locking position 74 is provided at the bottom of metering chamber 73. The leak-proof locking position 74 is a cylindrical structure, forming an annular space between itself and the peripheral wall of metering chamber 73. Spring 5 is installed in this annular space. The outer diameter of the leak-proof locking position 74 is smaller than the diameter of the valve plate mounting groove 35 at the bottom of piston 3. The top of the leak-proof locking position 74 contacts and abuts against the first valve plate 8a installed on the bottom of piston 3 to precisely limit the downward movement of piston 3. This also protects the spring from over-compression, preventing its function from being affected.

[0066] Preferably, the suction port 33 on the piston 3 is located inside the anti-leakage locking position 74. In this way, when the anti-leakage locking position 74 abuts against the first valve plate 8a, the first valve plate 8a will be pressed against the piston 3, which further improves the sealing performance of the first valve plate 8a to the periphery of the suction port 33 and can effectively prevent the cleaning agent from leaking due to slight water surface sway when the water tank is full.

[0067] In this embodiment, the automatic detergent dispenser uses a downward-facing connecting rod 6 located outside the container 7. When the water level drops, the connecting rod 6 touches the bottom to replenish the detergent in the storage chamber 72 into the metering chamber 73. When the water level rises, the connecting rod 6 moves downward due to its own weight to dispense detergent into the water, achieving the effect of dispensing detergent when the water is full and preparing detergent when the water is low.

[0068] like Figure 2 As shown, when the water level in the tank is high, the automatic detergent dispenser is in a floating state. At this time, the pendant 9 pulls down the piston 3 through the connecting rod 6. The first valve plate 8a at the bottom of the piston 3 abuts against the top of the anti-leakage position 74, discharging the detergent in the metering chamber 73 from the injection hole 71 and injecting it into the water tank.

[0069] like Figure 3As shown, when the user empties the water tank, the liquid level in the water tank drops, the cleaning agent automatic adder drops with the liquid level, the drop 9 contacts the bottom of the water tank, the linkage 6 drives the piston 3 to go up, the liquid level continues to drop, when the piston limiting block 62 abuts on the fixed column of the second valve plate 8b, the piston 3 will be at the highest position, at this time, it is in the bottom-touching state, and the cleaning agent in the storage cavity 72 will be quantitatively supplemented into the quantitative cavity 73.

[0070] According to Figure 2 and Figure 3 two states, it is easy to know that the cleaning agent automatic adder of the embodiment can use the structure of the water tank, the buoyancy of the water in the water tank, and the functions of flushing and supplementing water to achieve the purpose of automatically and accurately adding cleaning agent. The cleaning agent automatic adder will automatically and accurately add a certain amount of cleaning agent once every time the water tank is used, and will not automatically add when the water tank is not used for a long time, which can effectively ensure the stability of the cleaning agent concentration in the water tank and avoid wasting cleaning agent.

[0071] Embodiment 2:

[0072] A cleaning agent automatic adder can accurately add cleaning agent, as shown in Figure 1 、 Figures 4-7 、 Figure 9 and Figure 10 , which is specially designed as follows:

[0073] In this embodiment, the cleaning agent automatic adder is a top-touching type.

[0074] Specifically, the cleaning agent automatic adder includes a container 7, a piston 3, a first one-way valve, a second one-way valve, a spring 5, and a linkage 6.

[0075] As shown in Figure 1 、 Figure 4 、 Figure 5 、 Figure 6 , the container 7 is a rotary body structure with an open top, and a storage cavity 72 and a quantitative cavity 73 are vertically and vertically arranged and communicated in it from top to bottom, and the quantitative cavity 73 is in communication with the outside. The storage cavity 72 and the quantitative cavity 73 are both used for storing cleaning agent, and the inner diameter of the storage cavity 72 is larger than that of the quantitative cavity 73. When the container 7 is placed in water with the open top upwards, it can float upright on the water surface, so that the cleaning agent automatic adder as a whole can float on the water surface in a stable upright posture.

[0076] As shown in Figure 4 , the piston 3 is arranged in the quantitative cavity 73 and coaxially arranged with the axis of the quantitative cavity 73, and the peripheral wall of the piston 3 is dynamically sealed with the peripheral wall of the quantitative cavity 73 through a sealing ring. Specifically, as shown in Figure 10As shown, the peripheral wall of the piston 3 is provided with a sealing groove 34, and a small sealing ring 4 is installed in the sealing groove 34, and the piston 3 is in dynamic sealing cooperation with the peripheral wall of the metering cavity 73 through the small sealing ring 4. The piston 3 can be moved upward or downward along the axis of the metering cavity 73 under the action of an external force, and the moving direction depends on the action direction of the external force.

[0077] The first one-way valve and the second one-way valve are arranged at the metering cavity 73 to control the conduction state of the storage cavity 72 and the metering cavity 73. The first one-way valve is integrally installed on the piston 3 and can move synchronously with the piston 3, and the second one-way valve is arranged below the first one-way valve and is relatively fixed to the metering cavity 73 and cannot move upward or downward along the axis of the metering cavity 73. The conduction directions of the first one-way valve and the second one-way valve are consistent, so that the cleaning agent in the storage cavity 72 needs to pass through the first one-way valve and the second one-way valve in sequence and then pass through the metering cavity 73 to reach the outside of the container 7. Specifically, the first one-way valve is unidirectional from the storage cavity 72 to the metering cavity 73, and the second one-way valve is unidirectional from the metering cavity 73 to the outside of the metering cavity 73. As known from the above, the first one-way valve can be affected by the negative pressure generated by the space between the first one-way valve and the second one-way valve when the piston 3 moves upward.

[0078] Specifically, as shown in Figure 4 , Figure 9 and Figure 10 , the peripheral wall of the piston 3 is provided with a sealing groove 34, and the two end faces are concave to form a circular valve plate mounting groove 35, and a center hole is arranged at the center position of the groove bottom of the valve plate mounting groove 35, and at the same time, a plurality of upward through suction holes 33 are arranged at the positions outside the center hole on the groove bottom of the valve plate mounting groove 35. The first one-way valve includes a flexible first valve plate 8a, which is installed by the structure of the piston 3 to realize the ability of one-way conduction. The first valve plate 8a includes a plate body 83 and a fixed column 81 connected to the back of the plate body 83, and the end of the fixed column 81 is provided with a clamping position 82. The plate body 83 of the first valve plate 8a is accommodated in the valve plate mounting groove 35 at the bottom of the piston 3 and seals the suction holes 33, the fixed column 81 is inserted into the center hole of the piston 3, the clamping position 82 passes through the center hole of the piston 3 to the other end and abuts against the piston 3 to prevent the first valve plate 8a from falling off.

[0079] As shown in Figure 4 and Figure 7As shown, the second one-way valve comprises a flexible second valve plate 8b which is installed with the valve seat arranged at the bottom end of the metering cavity 73 to realize the ability of one-way conduction. Specifically, the bottom end of the metering cavity 73 is provided with an end plate which serves as the valve seat of the second valve plate 8b, and the structure of the second valve plate 8b is the same as that of the first valve plate 8a which will not be described herein. The bottom center of the valve seat is upwardly recessed to form a circular groove, and a center hole penetrating upward and downward is arranged at the center of the groove, and a shooting hole 71 penetrating upward and downward is further arranged at the side of the center hole. The fixing column of the second valve plate 8b is inserted into the center hole of the valve seat, and the clamping position penetrates through the center hole of the valve seat to the other end and abuts against the valve seat to prevent the second valve plate 8b from falling off.

[0080] As shown in Figure 1 , Figure 4 and Figure 5 , the link rod 6 is a straight rod part which is vertically arranged in the use state. The extended end of the link rod 6 is located at the upper position outside the container 7, and the extended end of the link rod 6 is located in the metering cavity 73 and is fixedly connected with the piston 3, so that the link rod 6 penetrates into the metering cavity 73 from the storage cavity 72 in a vertically downward manner and is connected with the piston 3, so that the piston 3 can move up and down along with the link rod 6.

[0081] Specifically, the center position of the fixing column of the first valve plate 8a is provided with a through hole for the link rod 6 to pass through, and the center position of the fixing column of the second valve plate 8b is a closed entity which does not allow liquid to pass through. After the link rod 6 penetrates into the metering cavity 73 from the storage cavity 72 and the vent hole of the cover 1 in sequence, the link rod 6 penetrates through the through hole of the first valve plate 8a, and the bottom end of the link rod 6 is clamped and fixed by the two clamping blocks to prevent the first valve plate 8a from falling off.

[0082] As shown in Figure 1 , Figure 4 and Figure 5 , the bottom position in the metering cavity 73 is provided with a spring 5, the bottom end of the spring 5 is abutted against the second one-way valve, and the top end of the spring 5 is abutted against the bottom of the piston 3, so that the spring 5 can drive the piston 3 to reset upward.

[0083] As shown in Figure 6 , a leakage prevention clamping position 74 is further arranged at the bottom of the metering cavity 73, the leakage prevention clamping position 74 is a cylindrical structure which forms an annular space with the peripheral wall of the metering cavity 73, and the spring 5 is installed in the annular space. The outer diameter of the leakage prevention clamping position 74 is smaller than the diameter of the valve plate mounting groove 35 arranged at the bottom of the piston 3, and the top end of the leakage prevention clamping position 74 is abutted against the first valve plate 8a arranged on the bottom of the piston 3 to limit the downward displacement of the piston 3.

[0084] Preferably, the suction port 33 on the piston 3 is located inside the anti-leakage stop 74, so that when the anti-leakage stop 74 abuts against the first valve plate 8a, the first valve plate 8a will be tightly pressed against the piston 3, further improving the sealing of the first valve plate 8a to the periphery of the suction port 33, and effectively avoiding the leakage of cleaning agent due to the small amplitude of water surface fluctuation when the water tank is full.

[0085] It should be noted that when the limiting spring 5 is at the maximum length, the piston 3 will not enter the storage cavity 72 from the dosing cavity 73.

[0086] In this embodiment, the first one-way valve and the second one-way valve with the same flow direction are arranged in the dosing cavity 73 of the container 7 from top to bottom, respectively separating the dosing cavity 73 from the storage cavity 72 and the outside. At the same time, the first one-way valve is installed on the piston 3 and moves up and down with the piston 3, and the extended connecting rod 6 can use the bottom wall or top wall of the water tank or sink to control the movement of the piston 3 when the container 7 moves with the water level. In this way, when the piston 3 moves upwards, the first one-way valve can be opened due to the negative pressure generated by the enlarged front space, connecting the dosing cavity 73 with the storage cavity 72, and allowing the cleaning agent in the storage cavity 72 to supplement the dosing cavity 73. During this process, the second one-way valve can be in a closed state throughout the upward movement of the piston 3, without leaking the cleaning agent in the dosing cavity 73 or allowing water to contaminate the cleaning agent. When the piston 3 moves downwards, the first one-way valve will be quickly closed under pressure and will push the cleaning agent in the dosing cavity 73 towards the second one-way valve together with the piston 3, and the second one-way valve will be opened by the pushing action of the forced downward cleaning agent, connecting the dosing cavity 73 with the outside, allowing the cleaning agent in the dosing cavity 73 to be discharged. During this process, the first one-way valve can be in a closed state throughout the downward movement of the piston 3 due to the counter-thrust of the cleaning agent, without adding cleaning agent to the dosing cavity 73. Then, the upward piston 3 will also make the second one-way valve quickly close by the negative pressure generated above the second one-way valve. Therefore, the two processes of supplementing and discharging cleaning agent of this kind of automatic cleaning agent dispenser are independent processes that do not affect each other, which can accurately dose the cleaning agent and effectively prevent water from contaminating the cleaning agent in the dosing cavity 73. In addition, the container 7 that can float can make this kind of automatic cleaning agent dispenser float on the water surface, which is convenient to take and place, and has less impact on the installation space of the water tank or sink.

[0087] As Figure 1 , Figure 4 and Figure 5As shown, in order to cover the opening of the container 7, the container 7 is provided with a cover 1. The outer wall at the mouth of the container 7 is provided with two sealing ring grooves, each of which is provided with a large sealing ring 2. The cover 1 is detachably connected with the container 7 by threads to cover the top opening of the storage cavity 72, and the large sealing ring 2 seals the connection between the cover 1 and the container 7. The center of the cover 1 is provided with a vent hole for connecting the storage cavity 72 with the outside, facilitating the ventilation of the container 7 and the flow of the cleaning agent, and the vent hole is also used for the passage of the connecting rod 6.

[0088] As shown in Figure 1 , Figure 4 and Figure 5 , the cover can be a high cover, which has a certain depth inside, and when the cover 1 is connected to the container 7, the inside of the cover 1 will form a cavity above the opening of the container 7, further reducing the overall density of the container 7, so that the cleaning agent automatic feeder can be more stably erected in the water.

[0089] The cleaning agent automatic feeder of the embodiment can use the action of the connecting rod 6 touching the top when the water level rises to make the cleaning agent in the quantitative cavity 73 be put into the water, and use the action of the connecting rod 6 going up under the action of the spring 5 when the water level drops to make the cleaning agent in the storage cavity 72 be supplemented into the quantitative cavity 73, achieving the effect of putting cleaning agent when the water is full and preparing cleaning agent when the water is insufficient.

[0090] As shown in Figure 4 , when the water level in the water tank is high, the cleaning agent automatic feeder is in a floating state, and the top end of the connecting rod 6 just touches the top of the water tank, that is, in a touching state. When the water level continues to rise, the connecting rod 6 will drive the piston 3 to go down, compressing the spring 5, and the cleaning agent in the quantitative cavity 73 will be discharged from the injection hole 71 and injected into the water tank.

[0091] As shown in Figure 5 , when the user pours water, the water level in the water tank drops, and the cleaning agent automatic feeder also drops with the water level. The connecting rod 6 goes up under the action of the spring 5 and drives the piston 3 to go up. At this time, the cleaning agent in the storage cavity 72 will be supplemented into the quantitative cavity 73. When the water level continues to drop and the connecting rod 6 is separated from the top of the water tank, the cleaning agent automatic feeder is in a suspended state, and the piston 3 is in the highest position. At this time, the cleaning agent in the storage cavity 72 will be quantitatively supplemented into the quantitative cavity 73.

[0092] According to Figure 4 and Figure 5As shown in the two states, it is easy to know that the cleaning agent automatic adder of the embodiment can use the structure of the water tank and the buoyancy of water in the water tank and the functions of flushing and replenishing water to achieve the purpose of automatically and accurately adding cleaning agent. The cleaning agent automatic adder will automatically and accurately add a certain amount of cleaning agent once every time the water tank is used, and will not automatically add when the water tank is not used for a long time, which can effectively ensure the stability of the cleaning agent concentration in the water tank and avoid wasting cleaning agent.

[0093] Embodiment 3:

[0094] The embodiment further provides a bathroom device on the basis of the above-mentioned embodiments, and particularly adopts the following setting structure:

[0095] In the embodiment, the bathroom device comprises a water tank or a sink or other container for storing cleaning water and the cleaning agent automatic adder in Embodiment 1 or Embodiment 2. The sink uses the bottom-touching cleaning agent automatic adder, and the top-touching cleaning agent automatic adder can also be used if there is a top plate or other structure that can abut against the connecting rod 6 above the sink.

[0096] According to Figures 2-5 As shown in the two states of the cleaning agent automatic adders with two different structures in use, it is easy to know that the cleaning agent automatic adder of the embodiment can use the structure of the water tank or the sink and the buoyancy of water in the water tank or the sink and the functions of flushing and replenishing water to achieve the purpose of automatically and accurately adding cleaning agent. The cleaning agent automatic adder will automatically and accurately add a certain amount of cleaning agent once every time the water tank is flushed and replenished, and will not automatically add when the water tank is not used for a long time, which can effectively ensure the stability of the cleaning agent concentration in the water tank and avoid wasting cleaning agent.

[0097] The above merely provides a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
