Description

Technical Field

[0001] This utility model relates to the field of toilet tanks, and more particularly to a toilet tank water circuit, a toilet tank, and a toilet. Background Technology

[0002] Conventional toilets use water from the toilet tank to flush. To achieve automatic tank refilling and automatic stopping of refilling once the water level reaches the maximum, a float lever mechanism is typically used. The float descends as the water level drops, opening the water valve to refill the tank. As the water level rises after refilling, the float rises, and when it reaches the maximum level, its position pulls the lever mechanism to close the water valve.

[0003] When adding water, the inlet pipe is connected to the water in the toilet tank. Therefore, when there is negative pressure, pressure is generated by the flow of other water passages connected to the inlet, or when toilet water backflow occurs, the water in the tank will flow back, causing the water in the tank to contaminate the water source or other water passages.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome at least one of the shortcomings of the prior art and to provide a toilet tank water circuit, a toilet tank and a toilet.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a toilet tank water circuit, comprising: The water inlet pipe has an inlet end connected to a water source and an outlet end for filling the water tank with water, the outlet end having an opening facing downwards; A pontoon, installed inside a water tank and configured to move as the water level rises or falls; and The float guide movable part supports the float to slide in the vertical direction and has a float upper limit part to prevent the float from continuing to float after the water level in the water tank reaches the highest water level. When the float abuts the float upper limit part, it is used to cut off the water replenishment action to the water tank through the water inlet. The water outlet is located at a predetermined distance above the highest water level and above the upper limit of the float.

[0007] By setting an upper limit position on the float guide movable part, the water inlet valve is closed when the water level in the tank reaches the highest level, thereby stopping the water replenishment action of the tank. The water outlet of the inlet pipe is set at a predetermined distance above the highest water level and the upper limit position of the float, so that the opening of the water outlet is isolated from the water in the tank by air. Therefore, even if there is negative pressure or backflow of toilet water, the toilet tank will not backflow into the contaminated water source or other water circuits.

[0008] Preferably, the water inlet pipe and the float guide movable part are integrally formed, and the movable guide part has a through hole below the water outlet end. The through hole is located below the water outlet end in the vertical direction, and the projection of the through hole from bottom to top covers the opening of the water outlet end.

[0009] By using one-piece molding, the structure of the water channel is simplified and the manufacturing cost of the water channel is reduced. By covering the opening of the water outlet end with a projection from bottom to top, the through hole can be demolded in the vertical direction.

[0010] Preferably, the water inlet pipe includes a first water inlet channel extending laterally, with the water inlet end at the end in the lateral direction, the lateral direction being perpendicular to the direction in which the through hole extends.

[0011] By setting the first water inlet channel horizontally, the space occupied by the toilet water circuit in terms of height is reduced, while the first water inlet channel and the opening of the water outlet can be formed through each other during the molding process.

[0012] Preferably, the toilet tank water circuit further includes a connecting frame formed between the float guide movable part and the water inlet pipe, the connecting frame having a through hole whose axial direction is the radial direction of the water inlet pipe, and whose width is greater than the width of the opening of the water outlet end and the opening of the through hole when viewed from the axial direction of the through hole.

[0013] By setting the axial direction of the through hole of the connecting bracket to be radial to the water inlet pipe, the outer peripheral wall of the water inlet pipe is formed by mold closing in the direction and can be demolded.

[0014] Preferably, the toilet tank water circuit includes a flow restrictor located at the water inlet.

[0015] Preferably, the predetermined distance is not less than 20mm.

[0016] The predetermined distance is no less than 20mm, so that the water in the tank will not flow backwards when the water level is higher than the design water level due to manufacturing tolerances or other reasons.

[0017] Preferably, the toilet tank water circuit includes a rectifier disposed on the opening at the outlet end, the rectifier being arranged with a dense array of downward-pointing spouts.

[0018] Preferably, the toilet tank water circuit includes a water source pipe, and the water inlet pipe further includes a second water inlet channel extending laterally, the second water inlet channel being juxtaposed with the first water inlet channel in the lateral direction; the right end of the water inlet pipe in the lateral direction is provided with a connecting part for connecting to the water source pipe, the connecting part being connected to the second water inlet channel.

[0029] The following will be combined with the appendix Figure 1 To be continued Figure 3 The technical solutions in the embodiments are described clearly and completely.

[0030] An embodiment of this utility model provides a toilet, which includes a toilet body (not shown) and a water tank (not shown). The water tank is equipped with a toilet water tank circuit. Figure 1 , Figure 2 and Figure 3 The toilet tank water circuit includes an inlet body 1 and a float 2. The inlet body 1 includes an inlet pipe 12 and a float guide 11, which are integrally formed. The inlet pipe 12 includes an inlet end 125, an outlet end 123, and a first inlet channel 121. The first inlet channel 121 connects the inlet end 125 and the outlet end 123. The inlet end 125 is used to connect to a water source, and the outlet end 123 is used to fill the tank with water to achieve the water replenishment operation. The inlet pipe 12 and the first inlet channel 121 extend in a horizontal direction, and the opening of the outlet end 123 faces downward. The horizontal direction is perpendicular to the vertical direction.

[0031] refer to Figure 1 and Figure 2The float 2 is slidably supported on the float guide 11 in a manner that allows it to slide relative to the float guide 11. The lever structure used by the float 2 to control the supply or cessation of water supply to the inlet 125 is well-known in the art and will not be described in detail here. The float guide 11 is constructed as a rod extending vertically, with the float 2 slidably mounted on the outer periphery of the rod. The upper end of the rod is connected to the inlet pipe 12 via a connecting frame. The connecting frame includes two connecting arms 131, with a through hole 132 formed between the two connecting arms 131. The through hole 132 is located below the opening of the outlet 123, so water flowing out of the opening directly enters the water tank through the open space formed by the through hole 132.

[0032] refer to Figure 2 and Figure 3 The rod of the float guide movable part 11 includes a through hole 111. The through hole 111 extends in the vertical direction and is located below the opening of the water outlet 123 and the through hole 132 in the vertical direction. The projection of the through hole 111 from bottom to top covers the opening of the water outlet 123. Moreover, the width of the through hole 132 is greater than the opening of the water outlet 123 and the width of the opening of the through hole 111. This ensures that there is no obstruction structure in the vertical direction of the opening of the water outlet 123. During molding, a core-pulling mechanism can be set from this direction, so that the opening of the water outlet 123 and the molding core of the first water inlet channel 121 collide at the water outlet.

[0033] A float upper limit part 112 is provided at the upper end of the rod-shaped part of the float guide movable part 11. The float upper limit part 112 protrudes radially outward from the periphery of the float guide movable part 11. When the float 2 rises, it can be located on its sliding path, so that after the water level in the water tank reaches the highest water level, the float 2 hits the float upper limit part 112 and stops moving.

[0034] The predetermined distance between the outlet of the water outlet 123 and the highest water level is not less than 20mm, preferably 20mm, 25mm, etc.

[0035] refer to Figure 2 and Figure 3 The water tank also includes a rectifier 3 with an opening at the outlet 123. The rectifier 3 is installed on the opening through the space of the through hole 132. The rectifier 3 is arranged with dense water outlets. The rectifier 3 injects water into the water tank by dividing and rectifying the water flow, thereby reducing the impact force of the water flow on the water in the water tank and reducing the noise during water replenishment.

[0036] The water tank circuit has a flow limiter installed at the inlet end 125 of the inlet pipe 12 to limit the amount of water entering the first inlet channel 121. It is understood that the flow limiter can be configured to control the flow rate in response to the movement of the float 2 or to control the opening and closing of the inlet end 125. The use of lever response by the flow limiter is a well-known technology in the art, and will not be described in detail here.

[0037] In one exemplary embodiment, the water tank water circuit further includes a water source pipe, and the water inlet pipe 12 further includes a second water inlet channel 122 extending laterally. The second water inlet channel 122 and the first water inlet channel 121 are arranged side by side in the lateral direction. The right end of the water inlet pipe 12 in the lateral direction is provided with a connecting part 124 for connecting the water source pipe. The connecting part 124 is constructed as a threaded connection. The thread can be a pipe thread. The connecting part 124 connects to the second water inlet channel 122, thereby delivering water at the water inlet end 125 to the water source pipe.

[0038] In one exemplary embodiment, the water in the tank is used to provide water for user components such as the human body cleaning parts on the toilet, and the water supply line can provide water flow for other cleaning components on the toilet for other functions such as brush rings.

[0039] The second water inlet channel 122 extends in the lateral direction and is placed side by side with the first water inlet channel 121 in the lateral direction. The water inlet end 125 and the water outlet end 123 are at their two ends in the lateral direction, so that the core-removing structure can be arranged in the lateral direction and thus integrally formed.

[0040] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
