Description

Technical Field

[0001] This utility model relates to the field of toilet technology, and in particular to a water tank device and a toilet. Background Technology

[0002] Existing smart toilets typically feature an independent plastic water tank, which connects to a booster pump via an outlet at the bottom of the tank to achieve zero-pressure flushing. However, the outlet of these existing plastic water tanks is generally integrally molded with the tank body, which presents the following problems:

[0003] 1) Due to space limitations, it is not possible to adjust the angle of the water tank outlet to accommodate booster pumps with different installation conditions during installation.

[0004] 2) Booster pumps with different displacements often have different inlet diameters, and a single outlet cannot be adapted to multiple booster pumps. Utility Model Content

[0005] This utility model provides a water tank device and a toilet, which allows the water outlet angle of the water tank to be adjusted and can be adapted to various booster pumps with different flow rates.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A water tank device includes a water tank body with a water outlet and a water outlet connector. The water outlet connector is detachably connected to the water outlet, and the water inlet end of the water outlet connector is rotatably connected to the water outlet. The water flow area of ​​the water outlet end of the water outlet connector can be changed by replacing different water outlet connectors.

[0008] Furthermore, the inlet end of the water outlet connector can be rotatably connected to the outlet, the water tank body has several fixed positions, and the water outlet connector has a connection position. The connection position can be locked to any fixed position, thereby changing the water outlet direction of the water outlet connector.

[0009] Furthermore, the fixing position is a fixing hole array around the water outlet, and the outer side of the water outlet connector is provided with a connecting seat, which is provided with a connecting hole that is adapted to any of the fixing holes.

[0010] Furthermore, the inlet end of the water outlet connector is equipped with a buckle, which is movably engaged with the edge of the inner orifice of the water outlet.

[0011] Furthermore, the outlet is provided with a snap-fit ​​section and an insertion section in sequence along the water outlet direction. The radial dimension of the snap-fit ​​end is smaller than that of the insertion section, so that the buckle is deformed only through the snap-fit ​​section.

[0012] Furthermore, a guide surface is provided at the connection between the snap-fit ​​section and the insertion section, and the snap fastener is provided with a guide surface that abuts and matches the guide surface.

[0013] Furthermore, the snap-fit ​​connection has notches on both sides of the water inlet end of the water outlet connector.

[0014] Furthermore, the outer facade of the water outlet connector is provided with a limiting protrusion extending outward along its radial direction. When the limiting protrusion abuts against the water tank body, the buckle is activated and engaged with the snap-fit ​​section.

[0015] Furthermore, the outer facade of the water outlet connector is provided with several sealing grooves, and sealing rings are provided in the sealing grooves, so that the water outlet connector is sealed and adapted to the insertion section.

[0016] A toilet includes a toilet body, which has a brush ring outlet and a jet outlet, and also includes a water tank device as described above. The water tank body is installed inside the toilet body, and the outlet end of the water connector is connected to one or more of the inlet end of a booster pump, the brush ring outlet, and the jet outlet via a connecting pipe.

[0017] The beneficial effects of this utility model are:

[0018] 1. The present invention proposes a water tank device, including a water tank body, the water tank body having a water outlet, and a water outlet connector connected to the water outlet. The water outlet direction of the water outlet connector is adjustable relative to the water tank body, thereby adapting to the internal space of the toilet under different installation conditions. At the same time, by replacing different water outlet connectors, the water flow area of ​​the water outlet end of the water outlet connector can be changed to adapt to booster pumps with different displacements.

[0019] 2. The water tank device proposed in this utility model has several fixed positions on the water tank body and a connection position on the water outlet connector. The connection position can be locked to any fixed position, thereby changing the water outlet direction of the water outlet connector and preventing the water outlet direction of the water outlet connector from shifting during use.

[0020] 3. The water tank device proposed in this utility model has a snap-fit ​​section and an insertion section arranged sequentially along the water outlet direction. When the water outlet connector is inserted into the water outlet, the snap-fit ​​will not abut against the wall of the insertion section after passing through the insertion section. The snap-fit ​​will only deform through the snap-fit ​​section, thereby reducing the resistance during the installation of the water outlet connector.

[0021] 4. The water tank device proposed in this utility model has a limiting protrusion extending radially outward on the outer side of the water outlet connector. When the limiting protrusion abuts against the water tank body, the buckle is actively engaged with the snap-fit ​​section, thereby improving the installation efficiency of the water outlet connector.

Detailed Implementation

[0037] The following is combined Figures 1-11 This utility model will be described in detail.

[0038] A water tank device 10 includes a water tank body 20, the water tank body 20 having a water outlet 201, and a water outlet connector 50. The water outlet connector 50 is detachably connected to the water outlet 201, and the water inlet end of the water outlet connector 50 is rotatably connected to the water outlet 201, that is, the water outlet direction can be changed by rotating the entire water outlet connector 50; at the same time, the water flow area of ​​the water outlet end of the water outlet connector 50 can be changed by replacing different water outlet connectors 50.

[0039] When in use, the water outlet connector 50 can be rotated to change the water outlet direction, making it easy to adjust the water outlet direction according to the current internal space of the toilet and to facilitate the connection of the internal pipes of the toilet, thereby adapting to the internal space of the toilet under different installation conditions. At the same time, the water outlet connector 50 can be replaced to change the water flow area at the water outlet end, thereby adapting to the booster pump 90 with different drainage capacity and expanding its application range.

[0040] In this embodiment, as Figures 2-5 As shown, the water tank body 20 has several fixed positions, and the water outlet connector 50 has a connection position. The connection position can be locked to any of the fixed positions, thereby fixing the water outlet connector 50 in the current water outlet direction and preventing displacement of the water outlet connector 50 during use. Furthermore, the fixed positions are fixed holes arranged in a circumferential array around the water outlet 201. The outer side of the water outlet connector 50 has a connecting seat 501, which has a connecting hole 502 that matches any of the fixed holes. During installation, the fastener passes through the connecting hole 502 and its thread matches the fixed hole, thereby locking the water outlet connector 50 to the water tank body 20. In other embodiments, pins, wires, or other components that can pass through the connecting hole 502 and the fixed hole can also be used to restrict rotation between the water outlet connector 50 and the water outlet 201.

[0041] In this embodiment, the fixing holes include a first fixing hole 401, a second fixing hole 402, and a third fixing hole 403. The number of fixing holes can also be changed according to requirements. For example... Figures 8-11 As shown, where Figure 8 and Figure 9The connection hole 502 is shown to be connected to the first fixing hole 401. Figure 10 and Figure 11 The connection hole 502 is connected to the third fixing hole 403. Therefore, the angle range from the first fixing hole to the third fixing hole 403 is the maximum angle adjustment range of the water outlet direction of the water outlet connector 50.

[0042] In this embodiment, as Figure 4 As shown, the inlet end of the water outlet connector 50 is equipped with a buckle 503, which is movably engaged with the edge of the inner orifice of the water outlet 201. The edge of the inner orifice of the water outlet 201 refers to the edge of the water outlet 201 that connects to the water tank body 20. During the rotation of the water outlet connector 50, the buckle 503 remains engaged with the edge of the inner orifice of the water outlet 201, ensuring that the water outlet connector 50 rotates circumferentially while preventing the water outlet connector 50 from detaching from the water tank body 20 axially.

[0043] In this embodiment, Figure 3 and Figure 4 Water outlet connector 50 with the same water flow area; in other embodiments, such as Figure 5 As shown, the water outlet connector 50 is opposite to... Figure 3 and Figure 4 The outlet end has a relatively small water flow area.

[0044] In this embodiment, as Figure 7 As shown, the outlet 201 is provided with a snap-fit ​​section 2011 and an insertion section 2012 in sequence along the water outlet direction. The radial dimension B of the snap-fit ​​section 2011 is smaller than the radial dimension C of the insertion section 2012. Therefore, when the water outlet connector 50 is inserted into the outlet 201, the snap fastener 503 will not abut against the wall of the insertion section 2012 after passing through it. The snap fastener 503 will only deform through the snap-fit ​​section 2011, thus avoiding continuous stress on the snap fastener 503 during the insertion of the water outlet connector 50 and reducing the resistance during the installation of the water outlet connector 50.

[0045] In this embodiment, as Figure 7 As shown, a guide surface 30 is provided at the connection between the snap-fit ​​section 2011 and the insertion section 2012. The snap fastener 503 has a guide surface 5031 that abuts against the guide surface 30. During installation, when the snap fastener 503 abuts against the guide surface 30, the snap fastener 503 deforms inward. When the snap fastener 503 passes over the snap-fit ​​section 2011, the snap fastener 503 unfolds under the action of elasticity, thereby snapping against the upper edge of the snap-fit ​​section 2011. The snap fastener 503 has notches on both sides of the water inlet end of the water outlet connector 50, so that the snap fastener 503 can easily deform when it abuts against the guide surface 30, which facilitates installation.

[0046] In this embodiment, as Figure 7As shown, the outer side of the water outlet connector 50 is provided with a limiting protrusion 504 extending outward along its radial direction. When the limiting protrusion 504 abuts against the water tank body 20, the buckle 503 is movably engaged with the snap-fit ​​section 2011, thereby improving the installation efficiency of the water outlet connector 50.

[0047] In this embodiment, the outer side of the water outlet connector 50 is also provided with several sealing grooves, and a sealing ring 60 is provided in the sealing groove, so that the water outlet connector 50 is sealed and adapted to the insertion section 2012 to prevent water leakage.

[0048] Example 2

[0049] The following is combined Figures 12-13 This utility model will be described in detail.

[0050] A toilet includes a toilet body 70, which has a brush ring outlet and a jet outlet, and also includes a water tank device 10 as described above. The water tank body 20 is installed inside the toilet body 70, and the outlet end of the water connector 50 is connected to one or more of the inlet end of the booster pump, the brush ring outlet, and the jet outlet via a connecting pipe 100.

[0051] In this embodiment, when the toilet installation does not require the offset device 80, such as Figure 12 As shown, the connection hole 502 of the water outlet connector 50 can be locked into any of the fixing holes and connected to the booster pump 90 through the connecting pipe 100; when the toilet installation requires the offset device 80, such as Figure 13 As shown, the connection hole 502 of the water outlet connector 50 can be locked to a specific fixing hole, so that the water pipeline avoids the shifter 80, thereby expanding the adaptability range of the water tank device 10.
