Example 1:
an automatic cleaning agent adder can accurately throw in cleaning agent, as shown in figures 1-3 and 6-10, and is particularly provided with the following structure:
in this embodiment, the automatic cleaning agent adder is a bottoming drop type.
Specifically, the automatic cleaning agent adder comprises a container 7, a piston 3, a first one-way valve, a second one-way valve and a link rod 6.
As shown in fig. 1-3 and fig. 6, the container 7 is a revolving body structure with an open top, and a storage cavity 72 and a dosing cavity 73 are formed in the container and vertically aligned from top to bottom and are communicated, and the dosing cavity 73 is communicated with the outside. Both the storage chamber 72 and the dosing chamber 73 are used for storing cleaning agent, and the inner diameter of the storage chamber 72 is larger than the inner diameter of the dosing chamber 73. The container 7 can float on the water surface vertically when placed in the water with the opening facing up, so that the automatic detergent adder as a whole can float on the water surface in a vertically stable posture.
As shown in fig. 2, the piston 3 is integrally disposed in the dosing chamber 73 and coaxially disposed with the axis of the dosing chamber 73, and the peripheral wall of the piston 3 is in sealing engagement with the peripheral wall of the dosing chamber 73 by a sealing ring, specifically, as shown in fig. 10, a sealing groove 34 is disposed on the peripheral wall of the piston 3, a small sealing ring 4 is mounted in the sealing groove 34, and the piston 3 is in dynamic sealing engagement with the peripheral wall of the dosing chamber 73 by the small sealing ring 4. The piston 3 can be moved up or down along the axis of the dosing chamber 73 by the action of an external force in a direction depending on the direction of the action of the external force.
The dosing chamber 73 is provided with a first one-way valve and a second one-way valve to control the conducting state of the storage chamber 72 and the dosing chamber 73. The first check valve is integrally installed on the piston 3, and can move synchronously along with the movement of the piston 3, and the second check valve is arranged below the first check valve and is relatively fixed in the dosing cavity 73, so that the second check valve cannot move upwards or downwards along the axis of the dosing cavity 73. The direction of conduction of the first and second one-way valves is uniform so that the cleaning agent in the storage chamber 72 needs to pass through the first and second one-way valves in sequence and then reach the outside of the container 7 through the dosing chamber 73. Specifically, the first check valve is in one-way communication from the reservoir chamber 72 to the dosing chamber 73, and the second check valve is in one-way communication from the dosing chamber 73 to the outside of the dosing chamber 73. From the above, the first check valve can be conducted by the negative pressure generated in the space between the first check valve and the second check valve, which is increased when the piston 3 moves upward.
Specifically, as shown in fig. 2, 9 and 10, a sealing groove 34 is provided in the peripheral wall of the piston 3, a circular valve plate mounting groove 35 is formed by concave both end surfaces, a center hole is provided in the center position on the bottom of the valve plate mounting groove 35, and a plurality of suction holes 33 penetrating upward are provided in the position on the bottom of the valve plate mounting groove 35 outside the center hole, however, the suction hole 33 may be one. The first one-way valve comprises a flexible first valve plate 8a which is mounted with the structure of the piston 3 to achieve one-way conduction capability. The first valve plate 8a comprises a sheet 83 and a fixing column 81 connected to the back of the sheet 83, and a clamping position 82 is arranged at the end part of the fixing column 81. The sheet body 83 of the first valve sheet 8a is accommodated in the valve sheet mounting groove 35 at the bottom of the piston 3 and shields and seals the suction hole 33, the fixing column 81 is inserted into the center hole of the piston 3, and 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 sheet 8a from falling off.
As shown in fig. 2 and 7, the second check valve includes a flexible second valve plate 8b that is mounted to enable unidirectional communication with a valve seat provided at the bottom end of the dosing chamber 73. Specifically, the bottom end of the dosing chamber 73 is provided with an end plate, which serves as a valve seat for the second valve plate 8b, and the structure of the second valve plate 8b is not described here with respect to the first valve plate 8 a. The bottom center of the valve seat is concaved inwards to form a circular groove, a center hole which penetrates up and down is arranged at the center of the groove, and an ejection hole 71 which penetrates up and down is also arranged at the side of the center hole. The fixed column of the second valve plate 8b is inserted into the central hole of the valve seat, and the clamping position passes through the central hole of the valve seat to the other end and is abutted on the valve seat to prevent the second valve plate 8b from falling off.
As shown in fig. 1-3, and fig. 8, the link lever 6 is a straight lever part that is arranged upright in the use state. The extending end of the link rod 6 is located at a lower position outside the container 7, and the extending end of the link rod 6 is located in the dosing chamber 73 and fixedly connected with the piston 3, so that the link rod 6 penetrates into the dosing chamber 73 and is connected with the piston 3 after passing through the second one-way valve in a vertically upward manner, and the piston 3 can move up and down along with the link rod 6.
Specifically, the center of the fixing post of the first valve plate 8a and the second valve plate 8b is provided with a through hole through which the link rod 6 passes. The link rod 6 passes through the perforation of the second valve plate 8b upwards in sequence and then passes through the perforation of the first valve plate 8a, the top end of the link rod 6 is provided with a displacement limiting clamping block 63 with the diameter larger than the perforation aperture of the first valve plate 8a, and the displacement limiting clamping block 63 is propped against the top end of the fixed column 81 of the first valve plate 8a to avoid falling off from the first one-way valve.
The bottom end of the chain link 6 is provided with a pendant 9, and the pendant 9 is preferably spherical, but can also be ellipsoidal or cubic. The diameter of the pendant 9 is larger than that of the link rod 6, the pendant 9 can be integrally formed at the bottom end of the link rod 6 or can be assembled by a related connecting structure, for example, a pendant limiting clamping block 61 with the outer diameter larger than that of the rod section is arranged at the bottom end of the link rod 6, the pendant 9 is sleeved on the link rod 6 through a through hole formed in the radial direction of the pendant limiting clamping block 61, and the pendant limiting clamping block 61 is positioned at the bottom of the pendant 9 to support the pendant.
In the case where the link rod 6 is not provided with the suspending drop 9, the density thereof is greater than that of water so that the link rod 6 can sink in the water. When the link rod 6 is provided with the suspending drop 9, the density of the link rod 6 can be larger than or smaller than that of water, but the density of the suspending drop 9 is required to be ensured to be larger than that of the water so as to improve the pull-down force of the link rod 6 on the piston 3, thus the link rod 6 can play a corresponding role, and the sensitivity of the action can be improved.
In this embodiment, the first check valve and the second check valve with the same conducting direction are sequentially disposed in the dosing chamber 73 of the container 7 from top to bottom, so as to separate the dosing chamber 73 from the storage chamber 72 and the outside, and meanwhile, the first check valve is mounted on the piston 3 to move up and down along with the piston 3, and the extended link rod 6 can control the movement of the piston 3 by using the bottom wall or the top wall of the water tank or the water tank when the container 7 moves along with the water level. Thus, when the piston 3 moves upwards, the first one-way valve can be opened under the negative pressure effect generated by the enlarged front space to conduct the quantifying cavity 73 with the storage cavity 72, so that the cleaning agent in the storage cavity 72 is supplemented to the quantifying cavity 73, and in the process, the second one-way valve can be in a closed state in the whole course of the upward movement of the piston 3, so that the cleaning agent in the quantifying cavity 73 cannot leak out, and water cannot invade to pollute the cleaning agent; when the piston 3 moves downwards, the first one-way valve is pressed to be rapidly closed and pushes the cleaning agent in the dosing cavity 73 to the second one-way valve together with the piston 3, the second one-way valve is pushed to be opened by the cleaning agent forced to move downwards, the dosing cavity 73 is communicated with the outside, the cleaning agent in the dosing cavity 73 is ejected, and in the process, the first one-way valve can be in a closed state in the whole course due to the reverse thrust of the cleaning agent in the descending process of the piston 3 and does not add the cleaning agent into the dosing cavity 73; the upward piston 3 will then also cause the second one-way valve to close rapidly by the negative pressure generated above the second one-way valve. Therefore, the independent processes of the cleaning agent supplementing process and the cleaning agent feeding process of the automatic cleaning agent adder are not affected, so that the cleaning agent can be accurately and quantitatively fed, and the condition that water invades the quantitative cavity 73 to pollute the cleaning agent can be effectively avoided; in addition, the container 7 capable of floating can enable the automatic cleaning agent adding device to float on the water surface, so that the automatic cleaning agent adding device can be conveniently taken and placed, and the influence of the installation space of a water tank or a water tank is small.
As shown in fig. 1 to 3, in order to conceal the opening of the container 7, a cover 1 is provided for the container 7. An upper sealing ring groove and a lower sealing ring groove are arranged on the outer wall of the opening part of the container 7, and a large sealing ring 2 is arranged in each sealing ring groove. The cap 1 is detachably connected to the container 7 by screw threads to cover the top opening of the storage chamber 72, and the large sealing ring 2 seals the connection of the cap 1 to the container 7. The central portion of the cap 1 is provided with a vent hole for communicating the storage chamber 72 with the outside to facilitate ventilation of the container 7 and facilitate outflow of the cleaning agent.
As shown in fig. 1 and 2, the lid may be a high lid having a groove of a certain depth therein, and when the lid 1 is attached to the container 7, the inside of the lid 1 forms a cavity over the opening of the container 7, further reducing the overall density of the container 7, and allowing the automatic detergent adder to stand more stably in water.
As shown in fig. 1 to 3, preferably, in order to improve the sensitivity of the action of the piston 3, the automatic cleaning agent adder is provided with a spring 5 in the dosing chamber 73, the spring 5 is sleeved on the link rod 6, the bottom end of the spring 5 is connected to the second one-way valve, the top end of the spring is abutted to the bottom of the piston 3, and the spring 5 can drive the piston 3 to reset upwards.
In order to limit the maximum length of the upward extension of the spring 5 and avoid the piston 3 from being pushed into the storage cavity 72, a piston limiting clamping block 62 with a diameter larger than the perforation aperture of the fixed column of the second valve plate 8b is arranged at the middle section of the connecting rod 6, which is positioned outside the container 7. The link rod 6 movably penetrates through the through hole of the fixed column of the second valve plate 8b, and when the link rod 6 moves up to the position where the piston limiting clamping block 62 abuts against the fixed column of the second valve plate 8b, the spring 5 can be prevented from continuously extending upwards.
In order to limit the maximum downward movement of the piston 3, a leak-proof detent 74 is also provided at the bottom of the dosing chamber 73, the leak-proof detent 74 being of cylindrical configuration forming an annulus with the peripheral wall of the dosing chamber 73, in which annulus the spring 5 is mounted. The external diameter of leak protection screens 74 is less than the diameter of valve block mounting groove 35 that piston 3 bottom set up, and the top of leak protection screens 74 is through contacting the first valve block 8a contact butt of installing on the piston 3 bottom and accurately restricting piston 3's volume of going down, also can protect the spring can not excessively compress like this, avoids the spring function to receive the influence.
Preferably, the suction inlet 33 on the piston 3 is located at the inner side of the anti-leakage clamping position 74, so that when the anti-leakage clamping position 74 is abutted against the first valve plate 8a, the first valve plate 8a is abutted against the piston 3, the sealing performance of the first valve plate 8a on the periphery of the suction inlet 33 is further improved, and the condition that the cleaning agent leaks due to small shaking of the water surface when the water tank is full of water can be effectively avoided.
In the automatic cleaning agent adder of the embodiment, the part of the chain rod 6 located outside the container 7 extends downwards, so that the cleaning agent in the storage cavity 72 can be supplemented into the quantifying cavity 73 by the action of bottoming the chain rod 6 when the water level is lowered, and the cleaning agent is put into the water by the action of self-weight descending of the chain rod 6 when the water level is raised, thereby achieving the effects of fully putting the cleaning agent into the water and preparing the cleaning agent for depletion.
As shown in fig. 2, when the water level in the water tank is high, the automatic detergent adder is in a floating state as a whole, at this time, the suspending drop 9 pulls down the piston 3 through the chain link 6, the first valve plate 8a at the bottom of the piston 3 abuts against the top end of the anti-leakage clamping position 74, and the quantitative detergent in the quantitative cavity 73 is discharged from the injection hole 71 and injected into the water tank.
As shown in fig. 3, when the user turns on water, the liquid level in the water tank drops, the automatic cleaning agent adder drops along with the water level, the suspending drop 9 contacts the bottom of the water tank, the link rod 6 drives the piston 3 to move upwards, the water level continues to drop, when the piston limiting clamping block 62 abuts against the fixed column of the second valve plate 8b, the piston 3 is at the highest position, and is at the bottoming state at the moment, and the cleaning agent in the storage cavity 72 quantitatively supplements the quantitative cavity 73.
According to the two states shown in fig. 2 and 3, it is easy to know that the automatic cleaning agent adder of the present embodiment can accomplish the purpose of automatically and precisely adding cleaning agent by utilizing the structure of the water tank and the buoyancy of water in the water tank and the functions of flushing and replenishing water of the water tank. When the water tank is used once, the automatic cleaning agent adder automatically and accurately adds a certain amount of cleaning agent once, the water tank is not used for a long time, the cleaning agent is not automatically added, the concentration stability of the cleaning agent in the water tank can be effectively ensured, and the cleaning agent is not wasted.

Both the storage chamber 72 and the dosing chamber 73 are used for storing cleaning agent, and the inner diameter of the storage chamber 72 is larger than the inner diameter of the dosing chamber 73. The container 7 can float on the water surface vertically when placed in the water with the opening facing up, so that the automatic detergent adder as a whole can float on the water surface in a vertically stable posture.
As shown in fig. 4, the piston 3 is integrally disposed in the dosing chamber 73 and coaxially disposed with the axis of the dosing chamber 73, and the peripheral wall of the piston 3 is in sealing engagement with the peripheral wall of the dosing chamber 73 by a seal ring, specifically, as shown in fig. 10, a seal groove 34 is disposed on the peripheral wall of the piston 3, a small seal ring 4 is mounted in the seal groove 34, and the piston 3 is in dynamic sealing engagement with the peripheral wall of the dosing chamber 73 by the small seal ring 4. The piston 3 can be moved up or down along the axis of the dosing chamber 73 by the action of an external force in a direction depending on the direction of the action of the external force.
The dosing chamber 73 is provided with a first one-way valve and a second one-way valve to control the conducting state of the storage chamber 72 and the dosing chamber 73. The first check valve is integrally installed on the piston 3, and can move synchronously along with the movement of the piston 3, and the second check valve is arranged below the first check valve and is relatively fixed in the dosing cavity 73, so that the second check valve cannot move upwards or downwards along the axis of the dosing cavity 73. The direction of conduction of the first and second one-way valves is uniform so that the cleaning agent in the storage chamber 72 needs to pass through the first and second one-way valves in sequence and then reach the outside of the container 7 through the dosing chamber 73. Specifically, the first check valve is in one-way communication from the reservoir chamber 72 to the dosing chamber 73, and the second check valve is in one-way communication from the dosing chamber 73 to the outside of the dosing chamber 73. From the above, the first check valve can be conducted by the negative pressure generated in the space between the first check valve and the second check valve, which is increased when the piston 3 moves upward.
Specifically, as shown in fig. 4, 9 and 10, a seal groove 34 is provided in the peripheral wall of the piston 3, a circular valve plate mounting groove 35 is formed by concave both end faces thereof, a center hole is provided in the center position on the bottom of the valve plate mounting groove 35, and a plurality of suction holes 33 penetrating upward are provided in the position on the bottom of the valve plate mounting groove 35 outside the center hole. The first one-way valve comprises a flexible first valve plate 8a which is mounted with the structure of the piston 3 to achieve one-way conduction capability. The first valve plate 8a comprises a sheet 83 and a fixing column 81 connected to the back of the sheet 83, and a clamping position 82 is arranged at the end part of the fixing column 81. The sheet body 83 of the first valve sheet 8a is accommodated in the valve sheet mounting groove 35 at the bottom of the piston 3 and shields and seals the suction hole 33, the fixing column 81 is inserted into the center hole of the piston 3, and 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 sheet 8a from falling off.
As shown in fig. 4 and 7, the second check valve includes a flexible second valve plate 8b that is mounted to enable unidirectional communication with a valve seat provided at the bottom end of the dosing chamber 73. Specifically, the bottom end of the dosing chamber 73 is provided with an end plate, which serves as a valve seat for the second valve plate 8b, and the structure of the second valve plate 8b is not described here with respect to the first valve plate 8 a. The bottom center of the valve seat is concaved inwards to form a circular groove, a center hole which penetrates up and down is arranged at the center of the groove, and an ejection hole 71 which penetrates up and down is also arranged at the side of the center hole. The fixed column of the second valve plate 8b is inserted into the central hole of the valve seat, and the clamping position passes through the central hole of the valve seat to the other end and is abutted on the valve seat to prevent the second valve plate 8b from falling off.
As shown in fig. 1, 4 and 5, the link lever 6 is a straight lever part which is arranged upright in the use state. The extension end of the link rod 6 is located at an upper position outside the container 7, and the extension end of the link rod 6 is located in the dosing chamber 73 and fixedly connected with the piston 3, so that the link rod 6 penetrates into the dosing chamber 73 and is connected with the piston 3 after passing through the storage chamber 72 in a vertically downward manner, so that the piston 3 can move up and down following the link rod 6.
Specifically, the center of the fixing column of the first valve sheet 8a is provided with a through hole through which the link rod 6 passes, while the center of the fixing column of the second valve sheet 8b is a closed entity, and does not allow the passage of liquid. The chain link 6 penetrates through the vent hole of the cover 1 and the storage cavity 72 in sequence downwards, then penetrates into the quantifying cavity 73 and penetrates through the perforation of the first valve plate 8a, and the bottom end of the chain link 6 clamps the first valve plate 8a through the upper clamping block and the lower clamping block to fix the first valve plate, so that falling is avoided.
As shown in fig. 1, 4 and 5, a spring 5 is disposed at the bottom position in the dosing chamber 73, the bottom end of the spring 5 is grounded on the second one-way valve, the top end of the spring is abutted to the bottom of the piston 3, and the spring 5 can drive the piston 3 to reset upwards.
As shown in fig. 6, a leak-proof detent 74 is further provided at the bottom of the dosing chamber 73, and the leak-proof detent 74 is a cylindrical structure that forms an annulus with the peripheral wall of the dosing chamber 73, in which the spring 5 is mounted. The outer diameter of the leakage preventing catch 74 is smaller than the diameter of the valve plate mounting groove 35 provided at the bottom of the piston 3, and the top end of the leakage preventing catch 74 restricts the amount of downward movement of the piston 3 by contact abutment with the first valve plate 8a mounted on the bottom of the piston 3.
Preferably, the suction inlet 33 on the piston 3 is located at the inner side of the anti-leakage clamping position 74, so that when the anti-leakage clamping position 74 is abutted against the first valve plate 8a, the first valve plate 8a is abutted against the piston 3, the sealing performance of the first valve plate 8a on the periphery of the suction inlet 33 is further improved, and the condition that the cleaning agent leaks due to small shaking of the water surface when the water tank is full of water can be effectively avoided.
At the maximum length of the limiting spring 5, the piston 3 does not escape from the dosing chamber 73 and enter the storage chamber 72.
In this embodiment, the first check valve and the second check valve with the same conducting direction are sequentially disposed in the dosing chamber 73 of the container 7 from top to bottom, so as to separate the dosing chamber 73 from the storage chamber 72 and the outside, and meanwhile, the first check valve is mounted on the piston 3 to move up and down along with the piston 3, and the extended link rod 6 can control the movement of the piston 3 by using the bottom wall or the top wall of the water tank or the water tank when the container 7 moves along with the water level. Thus, when the piston 3 moves upwards, the first one-way valve can be opened under the negative pressure effect generated by the enlarged front space to conduct the quantifying cavity 73 with the storage cavity 72, so that the cleaning agent in the storage cavity 72 is supplemented to the quantifying cavity 73, and in the process, the second one-way valve can be in a closed state in the whole course of the upward movement of the piston 3, so that the cleaning agent in the quantifying cavity 73 cannot leak out, and water cannot invade to pollute the cleaning agent; when the piston 3 moves downwards, the first one-way valve is pressed to be rapidly closed and pushes the cleaning agent in the dosing cavity 73 to the second one-way valve together with the piston 3, the second one-way valve is pushed to be opened by the cleaning agent forced to move downwards, the dosing cavity 73 is communicated with the outside, the cleaning agent in the dosing cavity 73 is ejected, and in the process, the first one-way valve can be in a closed state in the whole course due to the reverse thrust of the cleaning agent in the descending process of the piston 3 and does not add the cleaning agent into the dosing cavity 73; the upward piston 3 will then also cause the second one-way valve to close rapidly by the negative pressure generated above the second one-way valve. Therefore, the independent processes of the cleaning agent supplementing process and the cleaning agent feeding process of the automatic cleaning agent adder are not affected, so that the cleaning agent can be accurately and quantitatively fed, and the condition that water invades the quantitative cavity 73 to pollute the cleaning agent can be effectively avoided; in addition, the container 7 capable of floating can enable the automatic cleaning agent adding device to float on the water surface, so that the automatic cleaning agent adding device can be conveniently taken and placed, and the influence of the installation space of a water tank or a water tank is small.
As shown in fig. 1, 4 and 5, in order to conceal the opening of the container 7, a lid 1 is provided for the container 7. An upper sealing ring groove and a lower sealing ring groove are arranged on the outer wall of the opening part of the container 7, and a large sealing ring 2 is arranged in each sealing ring groove. The cap 1 is detachably connected to the container 7 by screw threads to cover the top opening of the storage chamber 72, and the large sealing ring 2 seals the connection of the cap 1 to the container 7. The central portion of the cap 1 is provided with a vent hole for communicating the storage chamber 72 with the outside to facilitate ventilation of the container 7 and facilitate outflow of the cleaning agent, wherein the vent hole is also provided for the passage of the link rod 6.
As shown in fig. 1, 4 and 5, the lid may be a high lid having a groove of a certain depth therein, and when the lid 1 is attached to the container 7, the inside of the lid 1 forms a cavity over the opening of the container 7, further reducing the overall density of the container 7, and allowing the automatic detergent adder to stand more stably in water.
In the automatic cleaning agent adder of the embodiment, the part of the link rod 6 located outside the container 7 extends upwards, so that the cleaning agent in the dosing cavity 73 can be thrown into water by the action of the contact of the link rod 6 when the water level rises, and the cleaning agent in the storage cavity 72 can be supplemented into the dosing cavity 73 by the action of the upward movement of the link rod 6 by the action of the spring 5 when the water level falls, thereby achieving the effects of throwing the cleaning agent full of water and preparing the cleaning agent full of water.
As shown in fig. 4, when the water level in the water tank is high, the automatic detergent adder is in a floating state, the top end of the link rod 6 just contacts the top of the water tank, and in a top contact state, when the water level continues to rise, the link rod 6 drives the piston 3 to move downwards, the spring 5 is compressed, and the quantitative detergent in the quantitative cavity 73 is discharged from the injection hole 71 and injected into the water tank.
As shown in fig. 5, when the user discharges water, the liquid level in the water tank drops, the automatic cleaning agent adder drops along with the water level, the link rod 6 moves up under the action of the spring 5 and drives the piston 3 to move up, at this time, the cleaning agent in the storage cavity 72 is replenished into the dosing cavity 73, the water level continues to drop and the link rod 6 is separated from the top of the water tank, then the piston 3 is in a suspended state, and at this time, the cleaning agent in the storage cavity 72 is quantitatively replenished into the dosing cavity 73.
According to the two states shown in fig. 4 and 5, it is easy to know that the automatic cleaning agent adder of the present embodiment can accomplish the purpose of automatically and precisely adding cleaning agent by utilizing the structure of the water tank and the buoyancy of water in the water tank and the functions of flushing and replenishing water of the water tank. When the water tank is used once, the automatic cleaning agent adder automatically and accurately adds a certain amount of cleaning agent once, the water tank is not used for a long time, the cleaning agent is not automatically added, the concentration stability of the cleaning agent in the water tank can be effectively ensured, and the cleaning agent is not wasted.
Example 3:
the embodiment further provides a bathroom device based on the embodiment, and the bathroom device particularly adopts the following arrangement structure:
in this embodiment, the bathroom equipment includes a container for storing water for cleaning, such as a water tank or a water tank, and the automatic cleaning agent adder in embodiment 1 or embodiment 2. Wherein, the water tank uses a bottom-contact type automatic cleaning agent adder, and if a top plate or other structures capable of abutting against the link rod 6 are arranged above the water tank, the top-contact type automatic cleaning agent adder can also be used.
According to the two states of the automatic cleaning agent adding device with two different structures shown in fig. 2-5, it is easy to know that the automatic cleaning agent adding device of the embodiment can complete the purpose of automatically and accurately adding the cleaning agent by utilizing the structure of the water tank or the water trough and the buoyancy of the water in the water tank or the water trough and the functions of flushing and supplementing water. In the process of flushing and supplementing water in sequence, the automatic cleaning agent adder automatically and accurately adds a certain amount of cleaning agent once, the water tank is not used for a long time, the cleaning agent can not be automatically added, the concentration stability of the cleaning agent in the water tank can be effectively ensured, and the cleaning agent is not wasted.
The foregoing is merely illustrative of the present utility model, and the present utility model is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present utility model.
