Description

Technical field:

[0001] The present invention relates to a water-saving device, in particular to a water-saving device which controls the drainage volume by cooperating with a main water channel and an auxiliary water channel. Background technology:

[0002] In bathroom products, there are many places that need to use water-saving devices to control the drainage volume. Taking flush toilets as an example, some existing toilets have single drainage and some have double drainage. For double-drain toilets, it is necessary to install a double-drain drainage control device. Existing double-discharge toilets generally divide the water tank into two water chambers, and achieve the effect of large or small drainage by controlling the drainage of one or two water chambers. The disadvantage is that the structure is complex, the drainage volume is fixed and cannot be adjusted, and the use is limited. Summary of the invention:

[0003] In view of the above problems in the prior art, the present invention aims to provide a water-saving device with a simple structure and adjustable drainage volume, which controls the drainage volume through the coordination of a main water channel and an auxiliary water channel.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] A water-saving device that controls the drainage volume through the cooperation of a main water channel and an auxiliary water channel, includes a water tank, a main water channel and an auxiliary water channel provided in the water tank, which are respectively connected to the water in the water tank, the main water channel and the auxiliary water channel are connected at the bottom, a drainage component is provided in the main water channel, and a control component in the auxiliary water channel controls and adjusts the drainage volume of the auxiliary water channel and thereby adjusts the drainage volume of the drainage component in the main water channel.

[0006] Furthermore, the control assembly includes a float assembly and a linkage assembly that cooperate with each other; the float assembly extends into the attached water channel, and the float assembly is controlled to rise and fall through the linkage assembly to control the opening and closing of the attached water channel; the float assembly includes a fixed seat, a float, a connecting rod, and a movable eccentric pendulum block that cooperate with each other; the fixed seat is fixed on the outer cylinder wall of the main water channel, and the fixed seat is provided with a guide hole; a group of guide rods are provided at the lower part of the float and extend into the attached water channel, and a water channel is formed between the guide rods; the lower end of the connecting rod is fixed to the top of the float, and the upper end of the connecting rod moves up and down along the guide hole of the fixed seat and thus drives the float to move up and down as a whole; the movable eccentric pendulum block is hinged at the upper end of the connecting rod; the linkage assembly controls the movement of the movable eccentric pendulum block so that the movable eccentric pendulum block is placed on the upper surface of the fixed seat or detached from the fixed seat, thereby causing the float to float up or down to reach the set position to realize the opening or closing of the attached water channel.

[0007] Furthermore, the control component is a retractable overflow pipe arranged in the auxiliary water channel, and the overflow pipe is adjusted to a set position and fixed to achieve the purpose of controlling the drainage volume of the auxiliary water channel.

[0008] Furthermore, the linkage assembly includes a button assembly and a seesaw assembly that cooperate with each other; wherein, the seesaw assembly is hinged on the fixed seat, the button assembly presses one end of the seesaw assembly, and the other end of the seesaw assembly is lifted up and kicks the movable eccentric pendulum block so that its lower part is retracted and separated from the fixed seat, and the float assembly as a whole moves downward along the guide hole of the fixed seat for a fixed distance so that the float and the attached water channel are in a closed state.

[0009] Furthermore, the upper part of the connecting rod is a columnar structure, and the lower part is a rod-shaped structure; a limiting convex strip is provided on the outer edge of the upper columnar structure, and a limiting groove is provided at the matching position of the guide hole of the fixing seat. The upper columnar structure extends into the guide hole of the fixing seat and moves up and down. The limiting convex strip cooperates with the limiting groove to limit the position, and the lower rod-shaped structure is fixed to the upper surface of the float in an adjustable length manner.

[0010] Furthermore, air holes are provided on the upper surface of the float.

[0011] Furthermore, the overflow pipe is fixed to the attached water channel through thread or buckle adjustment.

[0012] Furthermore, the button assembly cooperates and is linked with the drainage assembly in the main water channel. The button assembly includes an extended support rod; the seesaw assembly is hinged on the fixed seat, and a horizontal rod and a downward inclined rod extend from each end of the hinge shaft. The support rod presses the horizontal rod at one end of the hinge shaft, and the inclined rod and the horizontal rod at the other end of the hinge shaft tilt up and kick the movable eccentric pendulum block to retract its lower part and separate it from the fixed seat.

[0013] Furthermore, a groove is opened on the top of the upper columnar structure of the connecting rod, and the movable eccentric pendulum block is hingedly set in the groove. An eccentric structure with one end larger and the other end smaller is formed along the hinge axis, and an inclination structure is formed at both ends respectively, which ensures that the two ends are swung out of the groove in turn during operation.

[0014] Using the above technical solution, during high-displacement drainage, the buoy rises and, upon reaching a set position, the eccentric cam swing block automatically swings to rest on a fixed bracket, keeping the buoy mouth and the auxiliary waterway open, allowing simultaneous drainage of the main and auxiliary waterways. When low-displacement drainage is required, the eccentric cam swing block retracts, and the buoy assembly moves downward as a whole, closing the buoy and auxiliary waterways. Only the main waterway is now drained. The drainage volume can also be adjusted by adjusting the height of the overflow pipe. Description of the drawings:

[0030] The present invention is described in detail below with reference to the accompanying drawings and embodiments:

[0031] Figures 1-14 Shown is an embodiment of the present invention.

[0033] In a specific embodiment, the control component has two implementation modes, such as Figures 1-6 For Example 1:

[0034] The control assembly 5 includes a buoy assembly 51 and a linkage assembly 52 that cooperate with each other; the buoy assembly 51 extends into the auxiliary waterway 3, and the buoy assembly 51 is controlled to rise and fall through the linkage assembly 52 to control the opening and closing of the auxiliary waterway 3; the buoy assembly 51 includes a fixed seat 511, a buoy 512, a connecting rod 513, and a movable eccentric pendulum block 514 that cooperate with each other; the fixed seat 511 is fixed to the outer wall of the main waterway 2, and a guide hole 5111 is provided on the fixed seat 511; a group of guide rods 5121 are provided at the lower part of the buoy 512 and extend into the auxiliary waterway 3, and the guide rods 5121 are provided at the lower part of the buoy 21 form a water channel 5122; the lower end 5132 of the connecting rod 513 is fixed to the top of the buoy 512, and the upper end 5131 of the connecting rod 513 moves up and down along the guide hole 5111 of the fixing seat 511, thereby driving the buoy 512 to move up and down as a whole; the movable eccentric pendulum block 514 is hinged to the upper end of the connecting rod 513; the linkage assembly 52 controls the movement of the movable eccentric pendulum block 514, causing it to rest on or detach from the upper surface of the fixing seat 511, thereby causing the buoy 512 to float or descend to the set position, thereby opening or closing the auxiliary water channel 3. The upper surface of the buoy 512 is provided with an air hole 5123 to enable the buoy to quickly reset.

[0035] The linkage assembly 52 includes a button assembly 521 and a seesaw assembly 522 that cooperate with each other; wherein, the seesaw assembly 522 is hinged on the fixed seat 511, the button assembly 521 presses one end of the seesaw assembly 522, and the other end of the seesaw assembly 522 is lifted up and kicks the movable eccentric pendulum block 514 so that its lower part is retracted and separated from the fixed seat 511, and the float assembly 51 as a whole moves downward along the guide hole 5111 of the fixed seat 511 for a fixed distance so that the float 512 and the attached waterway 3 are in a closed state.

[0036] The upper portion 5131 of the connecting rod 513 is a columnar structure, and the lower portion 5132 is a rod-shaped structure. A limiting ridge 5133 is provided on the outer edge of the upper columnar structure, and a limiting groove 5112 is provided at the matching position of the guide hole 5111 of the fixing seat 511. The upper columnar structure extends into the guide hole 5111 of the fixing seat and moves up and down. The limiting ridge 5133 cooperates with the limiting groove 5112 to limit the position. The lower rod-shaped structure is fixed to the upper surface of the buoy in an adjustable length manner (it can be a threaded connection or a snap connection to ensure that the length of the connecting rod and thus the displacement of the attached waterway can be adjusted). A groove 5134 is provided at the top of the upper columnar structure of the connecting rod, and the movable eccentric pendulum block 514 is hingedly set in the groove 5134. It forms an eccentric structure with one end larger than the other end along the hinge axis, and the two ends form an inclination structure 5141 respectively. When in motion, it ensures that the two ends can extend out of the groove 5134 when they swing in sequence.

[0037] The button assembly 521 cooperates with the drainage assembly 4 in the main water channel 2, and the button assembly 521 includes a protruding support rod 5211; the seesaw assembly 522 is hinged on the fixed seat 511, and a horizontal rod and a downwardly inclined diagonal rod extend from each end of the hinge shaft. The support rod 5211 presses the horizontal rod at one end of the hinge shaft, and the diagonal rod and the horizontal rod at the other end of the hinge shaft tilt up and kick the movable eccentric pendulum block 514 to retract its lower part and separate it from the fixed seat.

[0038] While working:

[0039] This device is installed on products that need to control the drainage volume (such as inside a toilet tank). When the drainage volume is large, the float is in a floating state, and the float mouth and the auxiliary water channel outlet are normally open, so that the main and auxiliary water channels are drained at the same time; when a small displacement is required, the button assembly drives the eccentric cam pendulum block to retract, and the float assembly moves downward as a whole to close the float and the auxiliary water channel. At this time, only the main water channel is drained; after the drainage is completed, the external space replenishes water to the main and auxiliary water channels, and the float floats up. When it reaches the set position, the eccentric cam pendulum block will automatically swing and rest on the fixed bracket, so that the float mouth and the auxiliary water channel outlet are normally open, and return to the initial state to prepare for the next cycle.

[0040] like Figure 7-10 FIG. 1 is a schematic diagram of a threaded positioning structure of the overflow pipe in Example 2; FIG. Figure 11-14 This is a schematic diagram of the buckle positioning structure of the overflow pipe of Example 2:

[0041] The control component 6 is a retractable overflow pipe 7 disposed in the auxiliary water channel 3. The overflow pipe 7 is adjusted to a set position and fixed to control the drainage volume of the auxiliary water channel. The overflow pipe 7 can be adjusted and fixed to the auxiliary water channel through a thread 8 or a buckle 9.

[0042] While working:

[0043] This structure is installed on products that need to control the drainage volume (such as inside a toilet tank). The overflow pipe and height are adjusted according to demand. When the height exceeds the external water level, only the main water channel drains to achieve small-volume drainage. When the height of the overflow pipe is adjusted to be lower than the external water level, the main and auxiliary water channels drain at the same time to achieve large-volume drainage. Adjusting the height of the overflow pipe can change the drainage volume of the auxiliary water channel to achieve different large-volume drainage.
