TECHNICAL FIELD

[0001] The utility model relates to the field of bathroom equipment, especially a toilet water storage tank and a toilet. BACKGROUND

[0002] In the prior art, the conventional design of the water pump of the single-sided water tank is to install it outside the single-sided water tank. This layout has many shortcomings, the most notable of which is the adaptability of the single-sided water tank, which limits the flexibility of the design of the single-sided water tank and cannot be customized according to actual needs.

[0003] The current single-sided water tank needs to be adjusted in specification when applied to direct discharge toilets and siphon toilets, the main reason being that the sewage pipe of the direct discharge toilet needs to occupy a large amount of space at the back of the toilet, i.e. the water storage tank of the siphon toilet cannot be applied to the water storage tank of the direct discharge toilet. On the one hand, the existing single-sided water tank has low adaptability, and on the other hand, the production cost will also increase with the number of specifications.

[0004] At the same time, the water storage tank needs to have a certain amount of water storage capacity to meet the daily flushing needs of the toilet, otherwise it will directly affect the cleanliness of the toilet flushing. In order to meet the needs of direct discharge and siphon, the cross-sectional area of the siphon water tank will inevitably be reduced, resulting in a reduction in the overall water storage capacity according to the original height, affecting the flushing quality.

[0005] In view of the above problems, it is necessary to optimize the existing design to improve the application effect of the water storage tank and the flushing device. SUMMARY

The terms "above," "below," and "within" should be understood as including the stated number. The terms "first" and "second" should be understood as distinguishing technical features and not as indicating or implying relative importance, the quantity of indicated technical features, or the sequential relationship between indicated technical features.

[0030] Furthermore, unless otherwise defined, the technical and scientific terms used in this invention have the same meanings as commonly understood by one of ordinary skill in the art. The terminology used in this invention is for the purpose of describing particular embodiments only and not for limiting the invention.

[0031] It should be understood that, when used in this specification and the appended claims, the terms "comprising" and "including" indicate the presence of the described features, integrals, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or collections thereof.

[0032] Example 1: As Figures 1-3 As shown, the toilet water tank includes a tank body 10 with an opening at the top. An mounting plate 11 is provided on the upper edge of the tank body 10. The mounting plate 11 has mounting holes 111 at the positions corresponding to the toilet. The water tank can be fixed to the toilet through the mounting plate without the need to open additional mounting holes.

[0033] A water inlet 12 is provided on the side near the upper edge of the opening of the housing 10. The water inlet 12 is used to install the water inlet valve body 121. On the same side of the water inlet 12, there are an upper flush outlet 13 and a lower flush outlet 14. The upper flush outlet 13 and the lower flush outlet 14 are used to fix the upper flush fitting 131 and the lower flush fitting 141, respectively. It can be adapted to different toilets of the direct flush and siphon types. The water pump 20 is located at the bottom of the inner cavity of the housing 10. In order to facilitate the installation of the water pump 20, a positioning seat 15 is provided at the bottom of the inner cavity of the housing 10. The positioning seat 15 is a groove with a shape adapted to the water pump at the bottom of the inner cavity. In order to improve the firmness of the installation of the water pump 20, bolts can be added to the positioning seat 15 to fix the water pump 20.

[0034] Preferably, to ensure the secure installation of the casing 10, a hanging plate 16 is provided along the upper edge of the opening of the casing 10, making it convenient to mount the casing 10 on the toilet. To further improve the stability of the installation, the hanging plate 16 can be configured as a first hanging plate 161 and a second hanging plate 162, located at a 90-degree angle to each other on the upper edges of two sides, excluding the mounting plate side.

[0035] Preferably, the lower half of the side 101 of the tank body 10 is designed to be recessed, and its height is increased compared to conventional water tanks on the market, which improves the adaptability of the tank body 10 while ensuring water storage capacity. The corners 102 and 103 on the opposite side of the water inlet opening 12 of the tank body 10 are designed with chamfers, rounded corners, or recessed slopes, which improves the compatibility of the corners 102 and 103 of the tank body 10 with the toilet structure during installation.

[0036] Preferably, an overflow opening 17 is provided on one side of the upper edge of the tank 10. The overflow opening 17 can discharge water from the top when the tank 10 is full. The discharged water will flow into the toilet bowl instead of overflowing to the bottom, thus preventing overflow water from wetting the floor around the toilet if the inlet valve 121 malfunctions.

[0037] Example 2: Figures 4-5 As shown, a flushing device is provided, in which a water pump 20 is connected to a two-way solenoid valve 40 located in the upper part of a water storage tank 10 via a vertically arranged connecting pipe 30. The first outlet 401 of the two-way solenoid valve 40 is connected to an upper flushing fitting 131, and the second outlet 402 of the two-way solenoid valve 40 is connected to a lower flushing fitting 141. The two-way solenoid valve 40 is in the lower flushing mode when normally open, and in the upper flushing mode when triggered.

[0038] A one-way valve 142 is provided on the flushing pipe fitting 141. The one-way valve 142 is connected to the inlet valve body 121 through the conduit 143. Water can enter the flushing pipe fitting 141 from the inlet valve body 121 through the one-way valve 142. After flushing, the flushing water is directly replenished by the inlet valve body 121 without the need for water pump 20. This ensures the airtightness of the flushing water trap when the water pump fails, and avoids the generation of odors.

[0039] Example 3: As Figure 6 As shown, a toilet has a control cover 50 installed on the top of the toilet tank 10. The control cover 50 is electrically connected to a water pump 20 and a two-way solenoid valve 40, and the water pump 20 and the two-way solenoid valve 50 are controlled through the circuit of the control cover 50.

[0040] When the toilet needs to be flushed, pressing the flush button or triggering a sensor signal will cause the two-way solenoid valve 50 to switch to the upper flush outlet 131 (or remain in the lower flush outlet 141 state, depending on the specific needs) to discharge water. At the same time, the water pump 20 starts working, sending water from the tank 10 into the toilet's flushing system through the upper flush outlet 113 or the lower flush outlet 141.

[0041] The above merely describes a specific implementation of the present application, but the protection scope of the present application is not limited thereto, and any skilled person in the art can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present application, and these modifications or replacements should be encompassed within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
