Description

Technical Field

[0001] The utility model relates to the field of intelligent toilet seats, and particularly relates to an intelligent toilet seat with a built-in foam shield. Background Art

[0002] With the demand for functions such as deodorization of intelligent toilets by people, covering the toilet water seal with foam is a better solution. The foam shield can be covered after the toilet water seal, and the effects of splash prevention, adhesion prevention, odor prevention, and bacteria inhibition are very obvious. It protects the toilet environment and human health like a shield, so it is named the foam shield. The traditional foam device for generating the foam shield is arranged outside the intelligent toilet seat, which not only occupies space but also is not beautiful. There are also existing ones that place the foam device inside the intelligent toilet seat, which includes: a foam generator, a foam storage container, a liquid extraction pump, an air pump, etc. In the foam generator, water and foam liquid are mixed to form a mixed liquid, and then gas is introduced to make the mixed liquid form foam, which is injected into the toilet bowl to form a foam shield. The mixed liquid obtained in this way has a large water content, the mixing degree of water and foam liquid is poor, the foaming particles are uneven, the formed foam shield is thinner, and the residence time of the foam shield in the toilet bowl is shorter. For example, after the foam shield is placed for 60 minutes, the foam amount is less than 50%, and the cost is high.

[0003] In addition, the existing intelligent toilet seat is provided with a liquid injection port communicated with the foam storage container, and the liquid injection port is used to add foam liquid into the foam storage container. Some directly use a decorative cover to plug the liquid injection port to play a sealing role. When injecting liquid, the decorative cover needs to be pulled out, and it is easy to be contaminated or lost after being pulled out, which is inconvenient to use. At the same time, if there are foreign matters in the foam liquid, or other foreign matters such as insects enter the foam storage container through the liquid injection port, it is easy to cause blockage and increase the maintenance cost.

[0028] To make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the orientation terms such as up, down, left, right, front, back, inside and outside that appear or will appear in the text of the present utility model are only based on the accompanying drawings of the present utility model, and they do not specifically limit the present utility model.

[0029] See Figures 1-7 , the present utility model discloses an intelligent toilet seat with an internal foam shield, which includes a cover body and a foam device. The cover body includes a base 1, and a cavity 11 is provided inside the base 1. The foam device is installed in the cavity 11.

[0030] The foam device includes a mixing mechanism, a foaming joint 3 and a foaming liquid pumping mechanism 4. The foaming liquid pumping mechanism 4 is used for foaming and liquid pumping. The mixing mechanism includes a mixing body 2. The mixing body 2 is provided with a mixing chamber 21, and a water inlet 22, a liquid inlet 23, a liquid outlet 24 and a spraying port 25 that are respectively communicated with the mixing chamber 21. The foaming joint 3 is provided with a foaming channel 31. The foaming channel 31 is communicated with the liquid outlet 24 through the foaming liquid pumping mechanism 4, and the foaming channel 31 is communicated with the spraying port 25.

[0031] The intelligent toilet seat with an in-built foam shield of the present utility model is provided with a foam device. Water and foam liquid are respectively injected into the mixing chamber of the mixing body through the water inlet and the liquid inlet for mixing. The obtained mixed liquid is sprayed into the foaming channel of the foaming joint through the spraying port under the action of hydraulic pressure. Part of the mixed liquid is foamed in the foaming liquid pumping mechanism and injected into the foaming channel. At this time, the mixed liquid and the foam meet in the foaming channel. The high-speed mixed liquid and the foam interact with each other to make the water and the foam liquid mix for the second time, so that the water and the foam liquid are fully mixed, the mixing degree is good, the foam particles are uniform, the foaming effect is good, the foam volume of the generated foam shield is greater than 50% after being placed for 60 minutes, and the cost is effectively reduced.

[0032] Wherein, the foaming liquid pumping mechanism 4 is a foaming pump. The foaming pump not only has the function of liquid pumping, but also has the function of mixing the mixed liquid and gas to form foam. Therefore, after the mixed liquid in the mixing chamber is extracted by the foaming pump, foam is output into the foaming channel.

[0033] As Figure 6 shown, the foaming pump includes a pump body 41 and a motor 42 arranged at the bottom of the pump body 41. The top of the pump body 41 is provided with an air port 43, a liquid port 44 and a foam outlet 45. A rubber diaphragm and an eccentric wheel are arranged in the pump body 41. The motor vibrates the rubber diaphragm through the eccentric wheel, so that the rubber diaphragm generates suction or thrust, and acts on the mixed liquid and air in the mixing chamber. Specifically, when the rubber diaphragm moves downward, suction is generated, and the suction causes the mixed liquid to be sucked into the pump body from the liquid port, and air is sucked into the pump body from the air port; when the rubber diaphragm moves upward, thrust is generated, and the mixed liquid and air are pushed in the direction of the foam outlet, and the mixed liquid and gas are beaten into bubbles one by one and output from the foam outlet, that is, the foam is injected into the foaming channel and mixed with the mixed liquid sprayed from the spraying interface. The foaming pump can adopt the existing technical structure and will not be introduced in detail here. The foaming pump can adopt the foaming pump with the model PYFP310-XA of Shenzhen Pinya Technology Co., Ltd.

[0034] It should be noted that the cover body further includes a cover plate 2 and a seat ring 3 which are respectively movably connected to the base 1.

[0035] Specifically, as Figure 5As shown, one end of the foaming joint 3 is provided with a spraying interface 33 communicating with the spraying port 25, and the side wall is provided with a foaming interface 32 communicating with the foaming liquid extraction mechanism 4. The spraying interface 33 and the foaming interface 32 are respectively communicated with the foaming channel 31. The mixed liquid in the mixing chamber is sprayed into the foaming channel through the spraying interface under the action of hydraulic pressure. The foaming liquid extraction mechanism inputs the foam formed by foaming part of the mixed liquid into the foaming channel. The mixed liquid and the foam meet in the foaming channel. The collision of the high-speed mixed liquid and the foam enables the water and the foam liquid to be mixed for the second time. Compared with the traditional collision and mixing of the mixed liquid and the gas, in the present utility model, the water and the foam liquid are fully mixed, the mixing degree is good, the foaming particles are uniform, the foaming effect is good, and the foam amount of the generated foam shield is greater than 50% after being placed for 60 minutes, effectively reducing the cost.

[0036] Preferably, the axes of the spraying interface 33 and the foaming interface 32 do not intersect, so that the mixed liquid will not be dispersed by the foam, and the foam is evenly distributed in the foam channel, which is beneficial to full mixing and good foaming effect.

[0037] Furthermore, as Figure 5 shown, the present utility model further includes a foam nozzle 5. One end of the foam nozzle 5 is provided with a spraying chamber 51, and the other end extends out of the bottom of the base 1 and is provided with a foam spraying port 52. The other end of the foaming joint 3 is provided with a nozzle interface 34 communicating with the spraying chamber 51, and a foaming net 53 corresponding to the nozzle interface 34 is arranged in the spraying chamber 51. The other end of the foaming joint is inserted into the spraying chamber. The foam is injected into the foam nozzle from the foaming joint, and finally flows out of the base through the foam spraying port and is injected into the toilet bowl. Among them, the foam flows through the foaming net and spreads fully to form a water film, and the foaming effect is good.

[0038] Preferably, as Figure 5 shown, a stirring blade 26 movably connected to the mixing body 2 is arranged in the mixing chamber 21, and at least part of the horizontal projections of the stirring blade 26 and the water inlet 22 or the liquid inlet 23 overlap. When water enters the mixing chamber, it pushes the stirring blade to rotate, and the mixed liquid can be stirred to make the mixing more sufficient.

[0039] Preferably, a plurality of foaming holes (not shown in the figure) are arranged on the stirring blade 26. The arrangement of the foaming holes is beneficial to the full mixing of the water and the foam liquid in the mixing chamber.

[0040] Still further, as Figure 4 、 6As shown, the foam device further includes a foam storage container 6 and a liquid delivery mechanism 7. The foam storage container 6 is communicated with the liquid inlet 23 through the liquid delivery mechanism 7. The foam storage container 6 is used for storing foam liquid. The liquid delivery mechanism 7 is preferably a peristaltic pump, which can extract the foam liquid from the storage container regularly and quantitatively to the mixing chamber, and convey the foam liquid in the foam storage container to the liquid inlet, so as to be conveyed into the mixing body and mixed with water to form a mixed liquid of water and foam liquid. Preferably, a one-way check valve is arranged between the peristaltic pump and the liquid inlet to prevent water from flowing back into the foam storage. The path is successively the liquid outlet at the lower end of the foam storage -> peristaltic pump -> one-way check valve -> liquid inlet, and each component is connected by a seal (such as a silica gel tube).

[0041] Specifically, as Figure 4 shown, the foam storage container 6 is provided with a liquid injection port 61, and the top of the base 1 is provided with a liquid addition port 121. The liquid injection port 61 and the liquid addition port 12 are correspondingly arranged. The base 1 is provided with a liquid addition port 12 corresponding to the liquid injection port 61 of the foam storage container 6. The user can add foam liquid into the liquid injection port through the liquid addition port, so as to add the foam liquid into the foam storage container.

[0042] Preferably, as Figures 1-2 shown, the top of the base 1 is provided with a liquid addition cover 13 movably connected to the base 1. The liquid addition cover 13 is adapted to the liquid addition port 12. In order to prevent foreign objects from falling into the foam storage container, a liquid addition cover is provided on the liquid addition port of the base, and the liquid addition cover is used to seal the liquid addition port. When adding liquid, only need to open the liquid addition cover.

[0043] More preferably, as Figure 2 shown, the side wall of the liquid addition port 12 is provided with a first groove 121, and the liquid addition cover 13 is provided with a second groove 131. The first groove 121 and the second groove 131 are correspondingly arranged. A gap is formed between the first groove and the second groove. The user can insert a finger into the gap and then lift the liquid addition cover, which is convenient for the user to open the liquid addition cover and is easy to use.

[0044] Preferably, a protective net (not shown in the figure) is covered on the liquid injection port 61. The setting of the protective net further prevents foreign objects from falling into the foam storage container.

[0045] Preferably, as Figure 4 、 6 shown, the foam device further includes a pressure reducing valve 9 and a distribution valve 8. The pressure reducing valve 9, the distribution valve 8 and the water inlet 22 are communicated in sequence. Connecting the water pipe to the pressure reducing valve is beneficial to reducing the water pressure and protecting the equipment. The water enters the water inlet after passing through the distribution valve, supplies water to the mixing body, and enters the mixing chamber to be mixed with the foam liquid in the mixing chamber.

[0046] Preferably, as Figure 5As shown, the mixing body 2, the foaming joint 3 and the foam nozzle 5 are sequentially snap-connected.

[0047] Preferably, sealing rings are respectively sleeved at both ends of the foaming joint 3, and the sealing rings are used for the gaps between the injection interface and the injection port, as well as between the injection cavity and the nozzle interface.

[0048] The working principle of the foam device of the present utility model is as Figure 7 shown: First, add foam liquid into the foam storage container 6. Start the liquid delivery mechanism 7, the pressure reducing valve 9 and the distribution valve 8. The liquid delivery mechanism 7 transports the foam liquid in the foam storage container 6 to the mixing cavity 21 through the liquid inlet 23, and water is injected into the water inlet 22 through the pressure reducing valve 9 and the distribution valve 8 and is mixed with the foam liquid in the mixing cavity 21. Start the foaming liquid extraction mechanism 4 to pump the mixed liquid in the mixing cavity 21 into the foaming liquid extraction mechanism 4 for foaming to form foam, and then transport it to the foaming channel 31 through the foaming interface 32. At the same time, when the mixed liquid in the mixing cavity 21 reaches a certain amount, the mixed liquid is sprayed into the foaming channel 31 through the injection port 25 under the hydraulic action, collides with the foam, enables the water and the mixed liquid to be secondarily mixed, then flows through the foaming net 53 to form a water film, and finally is sprayed into the toilet bowl through the foam nozzle 5 to form a foam shield.
