Description

Technical Field

[0001] The invention relates to a drain valve with a cleaning agent. Background Art

[0002] In the prior art, in order to clean the toilet, a cleaning agent is usually provided on the toilet device. One method is to directly place the cleaning agent in the water tank, and the water in the water tank can dissolve the cleaning agent. In this way, the water tank and its internal accessories are soaked in the cleaning agent for a long time, which will affect the life of the water tank product and its internal accessories to a certain extent; and another method is to place the cleaning agent in a cleaning agent storage box, and lead a replenishing water flow flowing out of the water inlet valve in the water tank for replenishing the toilet water seal into the cleaning agent storage box, so that the cleaning agent is released into the toilet under the dilution of the replenishing water flow. In this way, when in use, only when the water inlet valve is filled with water, there is a replenishing water flow to bring out the cleaning liquid diluted with the cleaning agent and flow it into the toilet, and the cleaning agent cannot be released during the drainage process of the drain valve in the water tank, which will cause the toilet pipe to be unable to be fully cleaned when flushing, and the cleaning effect is poor. Summary of the invention

[0003] In order to solve the above problems, the present invention provides a drain valve with a cleaning agent.

[0004] To achieve the above-mentioned purpose, the technical solution of the present invention is: a drain valve with a cleaning agent, the base of the drain valve is provided with a drainage channel, an overflow pipe is installed on the base, the overflow pipe is provided with a accommodating chamber for accommodating the cleaning agent, the cleaning agent is diluted by water flowing into the accommodating chamber to form a cleaning liquid, and a first connecting port connecting the accommodating chamber and the drainage channel is opened on the base, and part of the water flowing into the drainage channel can flow into the accommodating chamber through the first connecting port to bring all or part of the cleaning liquid in the accommodating chamber into the drainage channel.

[0005] Preferably, the accommodating chamber is arranged at the bottom or side of the inner cavity of the overflow pipe and is communicated with the inner cavity of the overflow pipe.

[0006] Preferably, the bottom of the inner cavity of the overflow pipe forms the accommodating cavity.

[0019] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the present invention is further described below in conjunction with the accompanying drawings. The accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other accompanying drawings can be obtained based on these accompanying drawings without paying creative work.

[0020] like Figure 1 and Figure 2 As shown, a drain valve with a cleaning agent in a preferred embodiment of the present invention is arranged in a water tank (not shown), the drain valve comprises a valve body 10 and a base 20, the base 20 is provided with a drainage channel 11, an overflow pipe 30 is installed on the base 20, the overflow pipe 30 is provided with a receiving chamber 31 for accommodating a cleaning agent 40, the cleaning agent 40 is diluted by water flowing into the receiving chamber 31 to form a cleaning liquid, a first connecting port 21 connecting the receiving chamber 31 and the drain channel 11 is opened on the base 20, part of the water flowing into the drainage channel 11 can flow into the receiving chamber 31 through the first connecting port 21 to bring all or part of the cleaning liquid in the receiving chamber 31 into the drainage channel 11, so that the drain valve can also have cleaning liquid flowing into the toilet during the flushing process, the cleaning agent 40 has a better cleaning effect on the toilet, the cleaning agent 40 is arranged in the overflow pipe 30, and will not be diluted by the water in the water tank, thereby avoiding the problem that the water tank and its internal accessories are soaked in the cleaning agent 40 for a long time, which affects the product life to a certain extent.

[0021] The cleaning agent 40 can be a solid cleaning agent or a liquid cleaning agent. In this embodiment, the cleaning agent 40 is a block structure, and the accommodating chamber 31 can store a predetermined amount of water for diluting the cleaning agent 40. The accommodating chamber 31 is arranged at the bottom of the inner cavity of the overflow pipe 30 and is connected to the inner cavity of the overflow pipe 30. Preferably, the bottom of the inner cavity of the overflow pipe 30 directly forms the accommodating chamber 31, so that there is no need to separate a accommodating chamber 31 in the inner cavity of the overflow pipe 30, and the structure is simpler. A second connecting port 22 connecting the accommodating chamber 31 and the drainage channel 11 is further provided below the first connecting port 21. The first connecting port 21 and the second connecting port 22 are separated by a partition. The cleaning liquid in the accommodating chamber 31 can flow to the drainage channel 11 via the second connecting port 22. A baffle 50 is provided on the side of the second connecting port 22 close to the drainage channel 11 for preventing water in the drainage channel 11 from flowing into the second connecting port 22. The setting of the baffle 50 can prevent the water flow in the drainage channel 11 from flowing into the accommodating chamber 31 from the second connecting port 22 and hindering the outflow of the cleaning liquid in the accommodating chamber 31, so that the cleaning liquid in the accommodating chamber 31 can flow from the second connecting port 22 to the drainage channel 11 more smoothly.

[0022] In the present embodiment, the top end of the baffle 50 is connected to the top wall on the side of the second connecting port 22 close to the drainage channel 11, the baffle 50 is bent from the top end of the baffle 50 and extends downward, and the bottom end of the baffle 50 at least extends to a position corresponding to the bottom wall on the side of the second connecting port 22 close to the drainage channel 11. In the present embodiment, the bottom end of the baffle 50 extends below the bottom wall on the side of the second connecting port 22 close to the drainage channel 11.

[0023] In this embodiment, the size of the second connecting port 22 is preferably smaller than that of the first connecting port 21, so that the water in the drainage channel 11 can flow into the accommodating chamber 31 from the first connecting port 21 more quickly, and flow out of the accommodating chamber 31 from the second connecting port 22 more slowly, so that the water flow can stay in the accommodating chamber 31 for a short time, and can more fully bring out the cleaning liquid in the accommodating chamber 31.

[0024] In the present embodiment, the overflow pipe 30 is also connected to a water replenishment pipe (not shown), which is led out from a water inlet valve (not shown) and replenishes the water seal of the toilet (not shown) through the overflow pipe 30 when the water inlet valve takes in water. The replenishment water of the water replenishment pipe flowing into the overflow pipe 30 can flow into the accommodating chamber 31. In this way, when all the cleaning liquid in the accommodating chamber 31 is brought into the drainage channel 11, the replenishment water from the water replenishment pipe can fill the accommodating chamber 31 so that the accommodating chamber 31 stores a predetermined amount of water for diluting the cleaning agent 40. And it is known in the prior art that the water replenishment pipe is used to replenish the toilet water seal after the drain valve finishes draining. In this way, the water replenishment of the water replenishment pipe can also bring out some cleaning liquid into the toilet water seal and remain in the water seal after the drain valve finishes draining, and it will not be taken away until the next toilet flushing, thereby achieving a better cleaning effect.

[0025] like Figure 2 As shown, when the drain valve drains water, part of the water in the drain channel 11 can flow from the first connecting port 21 into the accommodating chamber 31 to bring all or part of the cleaning liquid in the accommodating chamber 31 from the second connecting port 22 into the drain channel 11 to clean the toilet.

[0026] It is worth noting that, in addition to being arranged at the bottom of the inner cavity of the overflow pipe 30, the accommodating chamber 31 in this embodiment can also be arranged at the side of the inner cavity of the overflow pipe 30 and communicated with the inner cavity of the overflow pipe 30. The position of the accommodating chamber 31 is not limited to this.

[0027] like Figure 3 and Figure 4As shown, another preferred embodiment of the present invention is a drain valve with a cleaning agent. The difference between this embodiment and the above embodiment is that the cleaning agent 40 of this embodiment is not a solid block structure, but a liquid. Specifically, a medicine box 60 for storing the liquid cleaning agent 40 is provided in the overflow pipe 30, and the inner cavity of the medicine box 60 forms a receiving cavity 31. Specifically, the medicine box 60 is detachably fixed to the bottom of the overflow pipe 30, so that it is convenient to replace the medicine box 60, or to remove the medicine box 60 to replenish the cleaning agent 40. Of course, the medicine box 60 can also be integrally formed in the overflow pipe 30. The medicine box 60 of this embodiment has a top opening 61 and a side opening 62, and the side opening is provided at the upper part of the medicine box 60. The position of the side opening 62 defines the liquid level of the cleaning agent 40 in the medicine box 60. In this embodiment, preferably, the size of the side opening 62 is smaller than the size of the top opening 61.

[0028] like Figure 3 As shown, when the drain valve is not draining, the liquid level of the cleaning agent 40 is flush with the side opening 62;

[0029] like Figure 4 As shown, when the drain valve drains water, part of the water in the drain channel 11 can flow from the first connecting port 21 to the inner cavity of the overflow pipe 30, and the water in the inner cavity of the overflow pipe 30 is filled to the top of the medicine box 60 and flows into the medicine box 60 from the top opening 61 of the medicine box 60 to dilute the cleaning agent 40 in the medicine box 60 and then flows out from the top opening 61 and the side opening 62. The cleaning liquid flowing out from the top opening 61 and the side opening 62 is fully or partially brought into the drain channel 11 by the water flow, so that the drain valve can also have cleaning liquid flowing into the toilet during the flushing process.

[0030] Alternatively, the medicine box 60 of this embodiment may not be provided with the side opening 62, but only with the top opening 61, and the water in the inner cavity of the overflow pipe 30 flows into the top opening 61 and brings out the diluted cleaning liquid from the top opening 61, which is also feasible.

[0031] The remaining structures not described in this embodiment are the same as those in the above embodiment and will not be described again here.

[0032] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, it should be understood by those skilled in the art that various changes in form and details may be made to the present invention without departing from the spirit and scope of the invention as defined in the appended claims, all of which are within the scope of protection of the present invention.
