Description
Technical Field
[0001] The invention belongs to the technical field of intelligent toilets and relates to a foaming device for an intelligent toilet. Background Art
[0002] Smart toilets mainly include flush toilets and siphon toilets. Both types will have some water retained in the toilet cavity. When the user uses it, the retained water will splash onto the human body, affecting the user's experience. Therefore, existing smart toilets are usually equipped with a foaming device, which can be turned on before the user uses it to form 20mm high-density foam to cover the water surface, reduce sewage splashing, and ensure hygiene and safety.
[0003] A specific foaming device, such as the Chinese patent application [Authorization Announcement No.: CN106894484B], discloses a foaming device and a toilet, including a liquid storage box, a foamer, a valve body and an inner cylinder. The valve body is passed through the liquid storage box and is provided with a water inlet pipe and a foaming outlet, and the water inlet pipe is provided with a jet hole; the inner cylinder is installed in the valve body and is provided with a foaming chamber connected to the foaming outlet, the foaming chamber is connected to the jet hole and forms a negative pressure zone under the action of the jet, and a liquid inlet channel and an air inlet channel connected to the negative pressure zone are also provided between the inner cylinder and the valve body to deliver the foaming liquid and gas to the foaming chamber to mix with water, the foamer is installed in the foaming chamber and operates under the action of the mixed liquid to generate foam; the liquid storage box is connected to the liquid inlet channel.
[0004] The above structure is that when foaming is required, the foaming chamber and the jet hole are connected and a negative pressure zone is formed under the action of the jet. The foamer is located in the foaming chamber. When tap water flows into the foaming chamber from the jet hole, the foaming liquid in the inner cylinder enters the foaming chamber from the liquid inlet channel, and the gas enters the foaming chamber from the air inlet channel, and mixing is achieved in the foaming chamber. However, at the same time, part of the mixed liquid also flows into the inner cylinder from the liquid inlet channel to mix with the foaming liquid. Therefore, after long-term use, the foaming liquid in the inner cylinder is continuously diluted, and the concentration of the foaming liquid is reduced, thereby affecting the foaming effect of the foaming device when used for a long time. Summary of the Invention
[0005] The purpose of the present invention is to address the above-mentioned problems in the existing technology and propose a foaming device for an intelligent toilet. The technical problem to be solved by the present invention is: how to solve the problem that the existing foaming device has poor foaming effect after long-term use.
[0006] The purpose of the present invention can be achieved through the following technical solutions:
[0007] A foaming device for an intelligent toilet comprises an installation box and a partition arranged in the installation box, a foamer is arranged in the installation box, and is characterized in that the partition divides the inner cavity of the installation box into a liquid storage cavity for storing foaming liquid and a foaming cavity for installing the foamer, an inlet for water and air to enter is provided in the foaming cavity, a liquid inlet pipe is provided in the foaming cavity, the liquid outlet of the liquid inlet pipe is located at the upper part of the foaming cavity, a water pump is installed on the installation box, the liquid inlet end of the water pump is connected to the bottom of the liquid storage cavity, the liquid outlet end of the water pump is connected to the liquid inlet pipe, and the bottom surface of the foaming cavity is higher than the bottom surface of the liquid storage cavity.
[0008] By arranging a partition in the installation box, the partition divides the inner cavity of the installation box into two mutually sealed and independent liquid storage chambers and foaming chambers. When foaming is needed, the water pump of the installation box is started to pump the foaming liquid in the foaming chamber into the liquid inlet pipe through the water pump, and the liquid outlet of the liquid inlet pipe is located at the upper part of the foaming chamber. The height difference design can avoid the mixture of foaming liquid, air and water in the liquid inlet pipe, and the liquid inlet end of the water pump is connected with the bottom of the liquid storage chamber, and the liquid outlet end of the water pump is connected with the liquid inlet pipe. The height difference between the bottom surface of the foaming chamber and the bottom surface of the liquid storage chamber makes the foaming liquid remaining in the liquid inlet pipe after the foamer is not working have the inertia to flow downward, ensuring that the foaming liquid in the liquid inlet pipe can quickly flow back after use, further avoiding the mixture in the foaming chamber from mixing with the foaming liquid in the liquid inlet pipe, and improving the foaming effect of the foamer after multiple uses.
[0009] And because the foaming effect is always consistent, the driving force required by the foaming device is the same, thereby achieving a better energy-saving effect.
[0010] In the foaming device of the above-mentioned smart toilet, the top wall of the installation box is recessed upward to form a placement cavity, the upper end of the liquid inlet pipe is embedded in the placement cavity, and a liquid gap is formed between the liquid outlet of the liquid inlet pipe and the top wall of the placement cavity.
[0011] By setting up the placement cavity, the liquid outlet of the liquid inlet pipe is located in the placement cavity, that is, higher than the top wall of the foaming cavity, thereby better avoiding the situation where the mixture enters the liquid inlet pipe and affects the concentration of the foaming liquid, and further ensuring the foaming effect when the foaming device is used multiple times. The liquid gap ensures that the foaming liquid flowing out of the liquid outlet of the liquid inlet pipe can flow out quickly along the outer wall of the liquid inlet pipe.
[0012] In the foaming device of the above-mentioned smart toilet, the foamer is columnar and arranged vertically, and the foaming liquid inlet of the foamer is opened on the outer wall and the bottom wall.
[0013] The foaming liquid inlet of the foamer is arranged on the bottom wall and the outer wall, and is located at a lower position on the foamer, so that the foaming liquid can quickly flow into the interior of the foamer to achieve foaming and improve foaming efficiency.
[0014] In the above-mentioned foaming device of the smart toilet, the inner side wall of the foaming chamber has a support plate arranged vertically, one side of the support plate is connected to one side of the liquid inlet pipe, and the foamer is located on the other side of the liquid inlet pipe.
[0015] The setting of the support plate, on the one hand, improves the stability of the liquid inlet pipe setting and improves the support for the liquid inlet pipe. On the other hand, the side of the liquid inlet pipe away from the foamer is filled with the support plate, so that less foaming liquid flows to this side, and more foaming liquid flows to the side close to the foamer. The foaming liquid can accumulate quickly and flow into the foamer, realizing rapid introduction, thereby improving the foaming efficiency.
[0016] In the above-mentioned foaming device of the smart toilet, the distance one between the upper end of the liquid inlet pipe and the side wall of the placement chamber close to the foamer is greater than the distance two between the upper end of the liquid inlet pipe and the side wall of the other side of the placement chamber.
[0017] The size design of spacing one and spacing two can further make the foaming liquid flowing out of the liquid outlet of the liquid inlet pipe flow to the side close to the foamer as much as possible, and the provision of spacing two can prevent the foaming liquid flowing out of the liquid inlet pipe from accumulating at the liquid outlet and can flow out smoothly, further improving the efficiency of the foaming liquid flowing into the foamer and improving the foaming efficiency of the foaming device.
[0018] In the above-mentioned foaming device of the smart toilet, the installation box includes a box body and a box cover. The opening of the box body is set upward, the box cover is buckled on the box body and covers the opening, the box cover protrudes upward to form the above-mentioned placement cavity, and a foamer is arranged in the box body.
[0019] The design of the box body and the box cover makes it easier to form the placement cavity and to install the foamer, thereby improving assembly efficiency and reducing processing costs.
[0020] In the foaming device of the above-mentioned smart toilet, an air inlet and a liquid inlet are provided on the box cover, and both the air inlet and the liquid inlet are connected to the liquid storage chamber.
[0021] When the water pump pumps part of the foaming liquid into the foaming chamber, it can be connected to the outside air through the air inlet pipe to achieve rapid air intake and maintain air pressure balance. When more foaming liquid is used, the foaming liquid can be added into the liquid storage chamber from the liquid inlet pipe, which improves the feeding and air pressure balance of the foaming device and ensures the stability of foaming.
[0022] In the above-mentioned foaming device of the smart toilet, the top wall of the placement cavity is flat and is arranged to be inclined upward from one side close to the foamer to the other side.
[0023] By tilting the top wall of the placement cavity, more foaming liquid flowing out of the liquid outlet of the liquid inlet pipe flows to the side close to the foamer, which facilitates the foaming liquid to flow into the foamer quickly and improves the foaming efficiency.
[0024] Compared with the prior art, the present invention has the following advantages:
[0025] 1. The height difference between the bottom surface of the foaming chamber and the bottom surface of the liquid storage chamber allows the foaming liquid remaining in the liquid inlet pipe to have the inertia to flow downward when the foamer is not working, ensuring that the foaming liquid can quickly flow back to the liquid inlet pipe after use, further avoiding the mixture in the foaming chamber from mixing with the foaming liquid in the liquid inlet pipe, and improving the foaming effect of the foamer after multiple uses.
[0026] 2. The size design of spacing one and spacing two can further make the foaming liquid flowing out of the liquid outlet of the liquid inlet pipe flow to the side close to the foamer as much as possible, and the provision of spacing two can prevent the foaming liquid flowing out of the liquid inlet pipe from accumulating at the liquid outlet and can flow out smoothly, further improving the efficiency of the foaming liquid flowing into the foamer and improving the foaming efficiency of the foaming device.

The liquid outlet 51a of the liquid inlet pipe 51 is higher than the foaming liquid inlet 31 of the foamer 3 and is located at the upper part of the foaming chamber 5. A water pump 7 is installed on the mounting box 1. The liquid inlet end 71 of the water pump 7 is connected to the bottom of the liquid storage chamber 4, and the liquid outlet end 72 of the water pump 7 is connected to the liquid inlet pipe 51. The bottom surface of the foaming chamber 5 is higher than the bottom surface of the liquid storage chamber 4.
[0039] By arranging a partition 2 in the installation box 1, the partition 2 divides the inner cavity of the installation box 1 into two mutually sealed and independent liquid storage chambers 4 and foaming chambers 5. When foaming is needed, by starting the water pump 7 of the installation box 1, the foaming liquid in the foaming chamber 5 is pumped into the liquid inlet pipe 51 through the water pump 7, and the liquid outlet 51a of the liquid inlet pipe 51 is higher than the foaming liquid inlet 31 of the foamer 3, so that when the foaming liquid flows from the liquid outlet 51a of the liquid inlet pipe 51 to the inlet 6 of the foaming chamber 5, the height difference design prevents the foaming liquid and the foaming liquid from mixing in the liquid inlet pipe 51. A mixture of air and water, and the liquid inlet end 71 of the water pump 7 is connected to the bottom of the liquid storage chamber 4, and the liquid outlet end 72 of the water pump 7 is connected to the liquid inlet pipe 51. Through the height difference between the bottom surface of the foaming chamber 5 and the bottom surface of the liquid storage chamber 4, the foaming liquid remaining in the liquid inlet pipe 51 after the foamer 3 is not working can have the inertia of flowing downward, ensuring that the foaming liquid in the liquid inlet pipe 51 can quickly flow back after use, further avoiding the mixture in the foaming chamber 5 and the foaming liquid in the liquid inlet pipe 51 from mixing, thereby improving the foaming effect of the foamer 3 after multiple uses.
[0040] like Figure 3 、 Figure 4 and Figure 6As shown, the top wall of the mounting box 1 is recessed upward to form a placement cavity 11, the upper end of the liquid inlet pipe 51 is embedded in the placement cavity 11, and a liquid gap 12 is formed between the liquid outlet 51a of the liquid inlet pipe 51 and the top wall of the placement cavity 11, the foamer 3 is columnar and arranged vertically, the foaming liquid inlet 31 of the foamer 3 is opened on the outer wall and the bottom wall, the inner wall of the foaming cavity 5 has a support plate 52 arranged vertically, one side of the support plate 52 is connected to one side of the water inlet pipe, the foamer 3 is located on the other side of the liquid inlet pipe 51, the distance between the upper end of the liquid inlet pipe 51 and the side wall of the placement cavity 11 close to the foamer 3 is -8 greater than the distance between the side wall on the other side of the placement cavity 11 and the top wall of the placement cavity 11 is flat and arranged horizontally.
[0041] like Figure 4-5 As shown, the installation box 1 includes a box body 13 and a box cover 14. The opening of the box body 13 is set upward, and the box cover 14 is buckled on the box body 13 and covers the opening. The box cover 14 protrudes upward to form the above-mentioned placement cavity 11. The bubbler 3 is arranged in the box body 13, and the box cover 14 is provided with an air inlet pipe port 14a and a liquid inlet pipe port 14b. The air inlet pipe port 14a and the liquid inlet pipe port 14b are both connected to the liquid storage cavity 4.
[0042] Example 2
[0043] The content of this embodiment is basically the same as that of the first embodiment, except that the top wall of the placement cavity 11 is flat and tilted upward from one side close to the foamer 3 to the other side.
[0044] By tilting the top wall of the placement chamber 11, more of the foaming liquid flowing out of the liquid outlet 51a of the liquid inlet pipe 51 flows to the side close to the foamer 3, which facilitates the foaming liquid to flow into the foamer 3 quickly and improves the foaming efficiency.
