Description

Technical Field

[0001] This utility model relates to the technical field of toilet flushing systems, and in particular to the technical field of switching devices. Background Technology

[0002] Toilets, commonly known as toilets, typically use two flushing methods: direct flushing and siphon flushing. A toilet flushing system generally has two outlets, one connected to the flushing side of the bowl (RIM side) and the other connected to the siphon flushing side (JET side). The RIM side outlet is usually located below and close to the toilet seat, while the JET side outlet is positioned lower (in the water reservoir).

[0003] Traditional toilet flushing systems typically use a water tank pump and a reversing valve to flush the toilet. This design requires the pump to be activated during a power outage to enable flushing. However, because the pump has a very high power output, the toilet flushing system must use a dedicated large capacitor or high-capacity battery to operate. Such batteries often have problems such as high cost, short lifespan, and safety hazards.

[0004] Based on this, a switch valve and a switching device can be installed in the main water inlet circuit to ensure a good flushing effect during normal use while solving the problem of flushing during power outages. However, how to combine the switch valve and the switching device into a single combination valve to reduce the size of the toilet flushing system, while also enabling the combination valve to be switched manually and electrically, is an urgent problem to be solved. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the prior art by proposing a dual-drive switching device, which is not only very compact in structure and can meet the toilet flushing needs in different scenarios, but also has strong flexibility in use.

[0006] To achieve the above objectives, this utility model proposes a dual-drive switching device, including a housing, a water-blocking mechanism, a manual switching mechanism, and a diaphragm. The housing is provided with an inlet, an outlet A, and an outlet B that are respectively connected to the switching cavity. The manual switching mechanism can be manually operated to use the pressure difference to prevent the diaphragm from blocking the water inlet, while simultaneously causing the water-blocking mechanism to switch between blocking outlet A and outlet B.

[0007] Preferably, the system also includes an electric switching mechanism, which can be electrically operated to switch the water-blocking mechanism between outlet A and outlet B.

[0008] Preferably, the manual switching mechanism and the electric switching mechanism can complete the waterway switching action without affecting each other.

[0009] Preferably, the water-blocking mechanism includes a rotating shaft and a baffle. The rotating shaft is rotatably connected to the switching cavity, and the baffle is fixed on the rotating shaft and can block water outlet A or water outlet B during the rotation of the rotating shaft.

[0010] Preferably, the manual switching mechanism includes a switching connecting block, a slider, and a return spring. The slider is slidably connected in the transverse groove of the switching connecting block, and one end of the rotating shaft extends to the platform of the switching connecting block. The switching connecting block can drive the rotating shaft to rotate clockwise during manual upward movement to achieve the water circuit switching function. When it reaches a certain height, the slider is guided by the track A located on the outer shell to move to the right along the transverse groove to the bottom. The return spring can drive the switching connecting block to reset downward. When the slider is on the right, it can simultaneously push the rotating shaft to rotate counterclockwise to achieve the water circuit switching function. When the switching connecting block is pushed down to near the bottom, it can move from the right end of the transverse groove to the left end and disengage from the rotating shaft via the track B located on the outer shell.

[0011] Preferably, the manual switching mechanism further includes a mechanical operating lever, which is slidably connected in the vertical slide rail of the housing. The switching connecting block is fixed on the mechanical operating lever and can slide vertically with the mechanical operating lever. The return spring is sleeved on the switching connecting block.

[0012] Preferably, the manual switching mechanism further includes a cam and a manual switch. The housing is provided with a water inlet channel connected to the water inlet and a valve seat located in the water inlet channel with a central hole. The mechanical operating lever can indirectly drive the manual switch away from the valve seat through the cam until the central hole is no longer closed.

[0013] Preferably, the electric switching mechanism includes a motor, the rotating shaft can be driven to rotate by the motor, and a gap is provided between the motor and the rotating shaft to provide a rotational clearance.

[0014] The beneficial effects of this utility model are:

[0015] 1) By setting a manual switching mechanism, the valve can be opened by working with the diaphragm and the water blocking mechanism by working with the water blocking mechanism to switch the water path. This creates a combination valve that integrates the switching function and the water path switching function in the toilet flushing system. The structure is very compact and can meet the toilet flushing needs in different scenarios. It is also highly flexible in use. The additional electric switching mechanism can also assist the manual switching mechanism to complete the water path switching action by electric control.

[0016] 2) By setting a rotating shaft and slider that can be intermittently engaged and disengaged between the water-blocking mechanism and the manual switching mechanism, the manual switching mechanism can be prevented from affecting the normal operation of the water-blocking mechanism during the period when only the electric switching mechanism is activated;

[0017] 3) By leaving a gap with a free-running stroke between the motor and the shaft in advance, the motor of the electric switching mechanism can be prevented from being forced to rotate by the shaft during the start-up of the manual switching mechanism.

[0018] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description

Detailed Implementation

[0027] See Figures 1 to 7The present invention relates to a dual-drive switching device, comprising a housing 1, a water-blocking mechanism 2, a manual switching mechanism 3, and a diaphragm 4. The housing 1 is provided with an inlet 12, an outlet A13, and an outlet B14 respectively connected to the switching cavity 11. The manual switching mechanism 3 can be manually operated to, on the one hand, use the pressure difference to prevent the diaphragm 4 from blocking the water inlet, and on the other hand, to switch the water-blocking mechanism 2 to block the outlets A13 and B14.

[0028] It also includes an electric switching mechanism 5, which can be electrically operated to switch the water blocking mechanism 2 between the water outlet A13 and the water outlet B14.

[0029] The manual switching mechanism 3 and the electric switching mechanism 5 can complete the waterway switching action without affecting each other.

[0030] The water-blocking mechanism 2 includes a rotating shaft 21 and a baffle 22. The rotating shaft 21 is rotatably connected to the switching cavity 11. The baffle 22 is fixed on the rotating shaft 21 and can block the water outlet A13 or the water outlet B14 during the rotation of the rotating shaft 21.

[0031] The manual switching mechanism 3 includes a switching connecting block 32, a slider 33, and a return spring 34. The slider 33 is slidably connected in the transverse groove 321 of the switching connecting block 32. One end of the rotating shaft 21 extends to the platform of the switching connecting block. The switching connecting block 32 can drive the rotating shaft 21 to rotate clockwise during manual upward movement to achieve the water circuit switching function. When it reaches a certain height, the slider 33 is guided to move to the right along the transverse groove 321 to the bottom by the track A15 located on the outer shell 1. The return spring 34 can drive the switching connecting block 32 to reset downward. When the slider 33 is on the right, it can simultaneously push the rotating shaft 21 to rotate counterclockwise to achieve the water circuit switching function. When the switching connecting block 32 is pushed down to near the bottom, it can move from the right end of the transverse groove 321 to the left end and disengage from the rotating shaft 21 by the track B16 located on the outer shell 1.

[0032] The manual switching mechanism 3 also includes a mechanical operating lever 31, which is slidably connected in the vertical slide of the housing 1. The switching connecting block 32 is fixed on the mechanical operating lever 31 and can slide vertically with the mechanical operating lever 31. The return spring 34 is sleeved on the switching connecting block 32.

[0033] The manual switching mechanism 3 also includes a cam 35 and a manual switch 36. The housing 1 is provided with a water inlet channel connected to the water inlet 12 and a valve seat 17 located in the water inlet channel and having a central hole. The mechanical operating lever 31 can indirectly drive the manual switch 36 away from the valve seat 17 through the cam 35 until the central hole is no longer closed.

[0034] The electric switching mechanism 5 includes a motor 51, and the rotating shaft 21 can be driven to rotate by the motor 51. A gap 211 is provided between the motor 51 and the rotating shaft 21 to provide a rotational clearance angle.

[0035] The working process of this utility model:

[0036] 1) The working process of the manual switching mechanism 3:

[0037] See Figure 5 When the user pulls the mechanical operating lever 31 upward, the cam 35, which is linked to the mechanical operating lever 31, drives the manual switch 36 away from the valve seat 17 until the center hole is no longer closed; at this time, the diaphragm 4 is lifted by the water flow due to the pressure relief of the back pressure chamber so that the inlet 12 can be filled with water normally (i.e., the valve is opened).

[0038] See Figure 4 As the user pulls the mechanical operating lever 31 upwards, the slider 33 moves upwards synchronously with the switching connecting block 32, and simultaneously slides to the right along the transverse slide groove 321 under the guidance of the track A15 when it reaches a designated height (when the switching connecting block 32 reaches its uppermost position, the slider 33 is precisely guided to the rightmost position by the track A15). After the user releases the lever, the compressed return spring 34 uses its elastic force to drive the switching connecting block 32 downwards, and the slider 33 moves downwards synchronously with the switching connecting block 32, and simultaneously slides to the right near the bottom. Under the guidance of track B16, the slider 33 slides to the left along the transverse slide groove 321 (when the switching connecting block 32 reaches the lowest position, the slider 33 is just guided to the leftmost position by track B16); in addition, the switching connecting block 32 can simultaneously drive the rotating shaft 21 to rotate clockwise during the upward movement so that the baffle 22 can switch between outlet A13 and outlet B14 by rotation, and the slider 33 can simultaneously push the rotating shaft 21 to rotate counterclockwise during the downward movement of the switching connecting block 32 so that the baffle 22 can switch between outlet A13 and outlet B14 by rotation.

[0039] The manual switching mechanism 3 can be separated from the electric switching mechanism 5 by the intermittent engagement between the slider 33 and the rotating shaft 21. Specifically, since the manual switching mechanism 3 moves the slider 33 to the leftmost end of the transverse slide 321 and disengages from the rotating shaft 21 when it is not in operation, the slider 33 can avoid affecting the rotation of the rotating shaft 21 during the operation of the electric switching mechanism 5.

[0040] 2) Working process of electric switching mechanism 5:

[0041] See Figure 6 The electric switching mechanism 5 can use the motor 51 to drive the rotating shaft 21 to rotate so as to realize the baffle 22 to switch between the outlet A13 and the outlet B14.

[0042] like Figure 3 As shown, since there is a free-running stroke between the motor 51 and the rotating shaft 21 (i.e., a gap 211 that provides a free rotation angle), the motor 51 will not be affected by the slider 33 and will not be driven to rotate by the rotating shaft 21 when it is not working.

[0043] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
