Technical Field

[0001] The utility model relates to a toilet, in particular to a solvent mixing device and an intelligent cover plate and an intelligent toilet using the same. Background Art

[0002] When using a smart toilet, there will be problems such as excrement causing splashing water and odor, which greatly affects the toilet experience. In order to solve the above problems, most smart toilets are currently equipped with a foam shield function, which forms a layer of foam on the water surface of the toilet to isolate the air and the water in the toilet, achieving the effect of splash and odor prevention.

[0003] Currently, there are two types of foam storage for smart toilets on the market: built-in and external. The built-in foam storage device places the foam storage device inside the smart toilet. To add foam, you need to open the corresponding liquid inlet on the smart toilet and pour the foam into the inside. The external type provides an external interface on the smart toilet for connecting an external foam bottle. To replace it, unscrew the external interface and the foam bottle on the smart toilet and then add the foam. These two methods of adding foam have the following shortcomings: both require complex operations on the smart toilet foam storage device, and the structure is complex, requiring additional reading of the instruction document to effectively perform the replacement action; at the same time, after repeated disassembly, it will affect the life of the assembly parts.

DETAILED DESCRIPTION

[0031] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The utility model relates to a solvent mixing device, comprising a connecting seat 100, an air intake component 200 and a liquid mixing component 300.

[0033] like Figure 1 and Figure 2 As shown, the interior of the connection seat 100 is hollow to form a cavity 120. The connection seat 100 is provided with a puncture structure 110, and a first channel 111 is provided inside the puncture structure 110. One end of the first channel 111 is connected to the cavity 120, and the cavity 120 can be connected to the outside of the connection seat 100 through the first channel 111. The puncture structure 110 can be a tip protruding from the connection seat 100, and the first channel 111 is opened along the length direction of the tip. The air intake component 200 is connected to the connection seat 100, and the air intake component 200 is connected to the cavity 120, and the cavity 120 can be connected to the outside atmosphere through the air intake component 200. The liquid mixing component 300 is connected to the connection seat 100, and the liquid mixing component 300 is connected to the cavity 120.

[0034] In actual operation, the solvent mixing device is used in conjunction with a solvent bottle. The solvent bottle containing the foaming agent is placed upside down on the connecting seat 100. A tinfoil or other puncturable sealing 420 structure is provided at the bottle mouth of the solvent bottle. The solvent bottle is inverted on the puncture structure 110, and the tinfoil on the solvent bottle is punctured through the puncture structure 110. The solvent in the solvent bottle can flow into the cavity 120 through a defined channel. The liquid mixing component 300 is connected to an external water supply system, which can be a water tank, a tap water pipe, etc. When water enters the liquid mixing component 300, the liquid mixing component 300 can generate negative pressure to draw the solvent in the cavity 120 into the liquid mixing component 300. The solvent and water are mixed in the liquid mixing component 300 and then discharged for use. Except for the bottle mouth, the rest of the solvent bottle is closed. The outside air enters the cavity 120 through the air inlet assembly 200, and then enters the solvent bottle through the first channel 111, achieving pressure stabilization inside the solvent bottle, ensuring that the solvent in the solvent bottle can smoothly flow into the cavity 120. After the solvent in the solvent bottle is used up, it can be directly taken out from the connecting seat 100, and then a new solvent bottle can be installed upside down on the connecting seat 100. The solvent mixing device can be used for most solvent bottles on the market that use tin foil or the like to seal 420, and has a simple structure, and is very convenient to replace, install and use.

[0035] The solvent mixing device can be applied to the smart cover, and the solvent can be a foaming agent. The solvent mixing device or the smart cover can also be applied to the smart toilet. When replacing the solvent bottle, the solvent bottle can be directly taken and placed without the need for cumbersome operations of replacing or replenishing the solvent.

[0036] In some specific embodiments of the present invention, Figure 2 and Figure 3As shown, the puncture structure 110 is that a boss 112 is provided on the upper part of the connecting seat 100. The boss 112 can be vertically extended upward from the top of the connecting seat 100. The interior of the boss 112 is hollow to form a first channel 111. The first channel 111 is vertically opened. A plurality of protrusions 113 are provided at the upper end of the boss 112, and each protrusion 113 is circumferentially distributed along the end of the convex shaft. The protrusion 113 can be in a pointed shape, etc. In this embodiment, four protrusions 113 are provided on the end of the boss 112, and the four protrusions 113 are distributed in a cross shape. When in use, the tin foil on the solvent bottle is punctured by the protrusion 113. The boss 112 extends into the bottle mouth, and the boss 112 is adapted to the shape of the bottle mouth, so that the solvent bottle is inverted on the boss 112 for fixing.

[0037] Among them, the solvent mixing device also includes a container 400. The container 400 is used to hold the solvent. The above-mentioned solvent bottle is one embodiment of the container 400. The shape of the container 400 can be various shapes such as bottle-shaped and box-shaped. The container 400 is provided with a liquid outlet 410. The liquid outlet 410 can be a cover structure, and the cover structure is fixed to the body of the container 400 by threads. The liquid outlet 410 is provided with a seal 420, and the seal 420 can be a structure such as tin foil, a rubber pad, and a film. A sealing ring 130 is sleeved on the outer wall of the boss 112. During installation, the boss 112 faces upward and the liquid outlet 410 faces downward. The liquid outlet 410 is on the boss 112, and the boss 112 penetrates upward into the liquid outlet 410. The end of the boss 112 abuts against the seal 420, and the seal 420 is punctured by the protrusion 113. The shape of the water outlet is adapted to the shape of the boss 112, and the sealing ring 130 abuts against the inner wall of the liquid outlet 410. The solvent in the container 400 enters the cavity 120 through the first channel 111. The container 400 can be inverted and fixed on the connecting seat 100 by using the cooperation of the boss 112 and the liquid outlet 410. Among them, the boss 112 and the liquid outlet 410 can be adapted to cylindrical shapes, or can be set to a prism or other shapes.

[0038] The air intake assembly 200 may be connected to an external pipeline, air duct, etc., or may be some powered air supply system, etc. In some embodiments of the present invention, Figure 1 and Figure 2As shown, the air intake assembly 200 includes an air pipe 210 and a connector 220. The air pipe 210 can be a hose or a metal pipe. A second channel 221 is provided inside the connector 220. The air pipe 210 and the connector 220 can be connected by plug-in. The air pipe 210 is connected to the second channel 221. The connector 220 is installed on the connecting seat 100, and the second channel 221 is connected to the cavity 120. That is, the cavity 120 can be connected to the air pipe 210 through the second channel 221. During installation, the end of the air pipe 210 away from the connector 220 is placed at a position at least higher than the boss 112. External air can enter the container 400 through the air pipe 210, the second channel 221, the cavity 120, and the first channel 111 to balance the air pressure inside the container 400. Further, the inner diameter of the first channel 111 is larger than the inner diameter of the second channel 221. Air enters the cavity 120 through the first channel 111 to form bubbles, which are smaller than the inner diameter of the first channel 111. The density of bubbles is smaller than that of liquid, and after entering the cavity 120, the bubbles can quickly rise through the first channel 111 and enter the container 400. At the same time, the small particle size of the bubbles can reduce the impact of the upward process on the downward flow of the solvent. A filter grid can be set at one end of the air pipe 210 away from the joint 220 to block solid impurities in the air during the inhalation.

[0039] In some specific embodiments of the present invention, Figure 2 and Figure 4 As shown, the interior of the connection base 100 is provided with an installation cavity 140, and the installation cavity 140 is located at the lower part of the connection base 100, and the installation cavity 140 may be located below the receiving cavity 120. The installation cavity 140 and the receiving cavity 120 are connected to each other. The bottom of the installation cavity 140 is open. The interior of the installation cavity 140 is provided with a step 141, and the step 141 may be located at the transition position between the installation cavity 140 and the receiving cavity 120. The step 141 may be continuously extended along the circumference of the installation cavity 140, or may be intermittently distributed at the same height position of the inner wall of the installation cavity 140. The connection base 100 is provided with a clamping hole 150, and the clamping hole 150 may be opened on the side wall of the connection base 100 at the corresponding position of the installation cavity 140. The joint 220 is provided with a clamping head 222, and the shape of the clamping head 222 is adapted to the shape of the clamping hole 150. During installation, the joint 220 is inserted into the installation cavity 140 from bottom to top. The upper part of the connector 220 abuts against the step 141, and the step 141 limits the depth of the connector 220 inserted into the installation cavity 140. Then the clamp head 222 is clamped in the clamp hole 150, so that the connector 220 is fixed on the connection seat 100. The outer wall of the connector 220 and the inner wall of the installation cavity 140 can be sealed by a rubber ring. The transition position between the installation cavity 140 and the receiving cavity 120 is blocked by the connector 220.

[0040] In some specific embodiments of the present invention, Figure 1 , Figure 2 and Figure 5 As shown, the liquid mixing assembly 300 includes a venturi tube 310 and a liquid inlet pipe 320.

The water inlet end 311, the constricted section 312, the throat section 313, the flared section 314, the mixing section 315 and the output end 316 are sequentially distributed and connected along the radial direction of the venturi tube 310. The constricted section 312 gradually decreases in a conical shape from the water inlet end 311 to the throat section 313. The inner diameter of the throat section 313 is the same as the inner diameter of the small-diameter end of the constricted section 312. The flared section 314 gradually expands in a conical shape from the throat section 313 to the mixing section 315. The small-diameter end of the expanding section 314 is similar to the inner diameter of the throat section 313, and the mixing section 315 is the same as the inner diameter of the large-diameter end of the expanding section 314. A connecting pipe 317 is provided on the side wall of the expanding section 314.
