Description

TECHNICAL FIELD

[0001] The present application relates to the field of bathroom, in particular to a switching type scale cleaning mechanism and an intelligent toilet. BACKGROUND

[0002] In order to improve water quality, the bathroom products such as intelligent toilet generally use the scheme of separately or jointly using descaling assembly and filtering assembly to effectively remove scale and impurities in water. However, the descaling assembly and filtering assembly on the market are mostly designed as independent individual products. In actual application, if both the two assemblies are needed to be configured, they often need to be installed at different positions of the waterway system of the intelligent toilet. This installation mode reduces the utilization rate of bathroom space and occupies a large installation space due to the dispersed layout of the assemblies.

[0003] It should be noted that the information disclosed in the above background section is only used to strengthen the understanding of the background of the present disclosure, and therefore can include information that does not constitute prior art known to those of ordinary skill in the art.

[0023] Compared with the prior art, the technical scheme provided by the embodiments of the present application brings at least the following beneficial effects:

[0024] The switching type scale cleaning mechanism and the intelligent toilet of the present application can be installed in the mounting seat according to needs. When water quality needs to be filtered, the user fixes the scale inhibition box with the filter material inside into the cavity of the mounting seat. At this time, the switch valve is in the closed state. The water flows into the scale inhibition box through the water inlet, and flows out from the outlet after the filtering effect of the filter material, and finally enters the waterway system of the intelligent toilet. When scale needs to be cleaned, the user first removes the scale inhibition assembly, and then fixes the scale removal box with the scale removal liquid inside into the cavity of the mounting seat. Subsequently, the switch valve is opened to establish a path between the water inlet and the water outlet. Under the action of air pressure or water pressure, the scale removal liquid flows to the water outlet through the liquid outlet hole of the scale removal box, and then enters the waterway system of the intelligent toilet to clean the scale. It can be seen that the switching type scale cleaning mechanism and the intelligent toilet of the present application unify the scale removal assembly and the scale inhibition assembly for installation and management through the mounting seat. Specifically, the scale removal box and the scale inhibition box are detachably fixed in the cavity of the mounting seat. Therefore, it is not necessary to install the two assemblies at different positions of the waterway system, thereby greatly saving space. At the same time, since it is not necessary to install the scale removal assembly and the filter assembly at different positions of the waterway system, the installation steps are simplified, and the installation difficulty is reduced. It is also important that, through the control of the switch valve, the scale removal liquid in the scale removal box can flow to the water outlet when scale removal is needed, and the water flow is filtered through the scale inhibition box when scale inhibition is needed. This switching type working principle enables the switching type scale cleaning mechanism to meet the two functional requirements of scale removal and filtering, further simplifies the system structure, and improves the flexibility of use. Finally, the scale removal assembly and the scale inhibition assembly can be integrated on the mounting seat. Since the scale removal box and the scale inhibition box can be detached from the mounting seat, the user can replace or clean them according to needs. Moreover, it is not necessary to manufacture and purchase two independent and complete assemblies separately. This not only saves space, but also may reduce the production cost to a certain extent.

DETAILED DESCRIPTION

[0042] In order to make the purpose, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0044] To improve water quality, smart toilets and other bathroom products typically use descaling and filtration components, either individually or simultaneously, to descale and filter the water. Currently, these components are usually separate products. When used together, they are installed in different locations within the smart toilet's water circuit, resulting in significant space consumption.

[0045] To address the aforementioned technical problems, this embodiment provides a switchable scale removal mechanism. (See reference...) Figures 1 to 3 As shown, Figure 1 This is an exploded view of the switching scale removal mechanism of this application. Figure 2 This is a schematic diagram of the switching scale removal mechanism of this application during the installation of the descaling components. Figure 3 This is a schematic diagram of the switching scale removal mechanism of this application when the scale inhibition component is installed.

[0046] The switching scale removal mechanism of this embodiment is used to be installed on the water flow pipeline of the water-using equipment, and includes: mounting base 11, scale removal component and scale inhibition component.

[0047] Mounting base 11 is provided with a cavity 110 for installing descaling components and scale inhibition components, a switching valve 13, and an inlet 112 and an outlet 113 connected to the cavity 110. The inlet 112 and the outlet 113 are connected and disconnected by the switching valve 13.

[0048] The descaling assembly includes a descaling box 16 for containing descaling fluid, and the descaling box 16 is provided with an outlet port 103 for discharging the descaling fluid. The descaling fluid can be any liquid with water purification function, such as existing descaling fluid or cleaning fluid.

[0049] The scale inhibition assembly includes a scale inhibition box 17 for accommodating filter media, the scale inhibition box 17 having an inlet 104 and an outlet 105. The cavity 110 is configured to detachably accommodate and fix either the descaling box 16 or the scale inhibition box 17. When the descaling box 16 is fixed within the cavity 110, the switch valve 13 is opened, and the liquid outlet 103 communicates with the water outlet 113, allowing the descaling liquid in the descaling box 16 to flow from the liquid outlet 103 to the water outlet 113 under air or water pressure. When the scale inhibition box 17 is fixed within the cavity 110, the switch valve 13 is closed, the inlet 104 communicates with the water inlet 112, and the outlet 105 communicates with the water outlet 113.

[0050] The working process of the switching scale removal mechanism in the above technical solution is as follows: (See reference) Figure 2 As shown, when limescale needs to be removed, the user first detachably fixes the descaling box 16 (containing descaling solution) into the cavity 110 of the mounting base 11. Then, the user opens the switch valve 13, establishing a passage between the inlet 112 and the outlet 113. Under air or water pressure, the descaling solution flows through the outlet hole 103 of the descaling box 16 to the outlet 113, and then enters the water system of the smart toilet to clean the limescale. After the descaling solution is used up, the descaling box 16 is disassembled and cleaned or replaced as necessary.

[0051] When water filtration is required, refer to Figure 3 As shown, the user detachably fixes the scale inhibitor box 17 (containing filter media) into the cavity 110 of the mounting base 11. With the switch valve 13 in the closed state, the inlet 112 is connected to the inlet 104 of the scale inhibitor box 17, and the outlet 105 of the scale inhibitor box 17 is connected to the outlet 113. Water flows into the scale inhibitor box 17 through the inlet 112, is filtered by the filter media, flows out from the outlet 105, enters the outlet 113, and finally enters the water system of the smart toilet. Over time, the filter media may gradually become saturated or ineffective, at which point the scale inhibitor box 17 needs to be removed and replaced with new filter media.

[0052] It can be seen that the switching scale cleaning mechanism and the intelligent toilet of the above technical solutions integrate the scale removal component and the scale inhibition component through the mounting seat 11 for installation and management. Specifically, the scale removal box 16 and the scale inhibition box 17 are detachably fixed in the cavity 110 of the mounting seat 11, so that the two components do not need to be installed at different positions of the waterway system, thereby greatly saving space. At the same time, since the scale removal component and the filter component do not need to be installed at different positions of the waterway system, the installation steps are simplified and the installation difficulty is reduced. It is also important that through the control of the switch valve 13, the scale removal liquid in the scale removal box 16 can flow to the water outlet 113 when scale removal is needed, and the water flow is filtered through the scale inhibition box 17 when scale inhibition is needed. This switching working principle enables the switching scale cleaning mechanism to meet the two functional requirements of scale removal and filtration, further simplifies the system structure, and improves the flexibility of use. Finally, the scale removal component and the scale inhibition component can be integrated on the mounting seat 11. Since the scale removal box 16 and the scale inhibition box 17 can be detached from the mounting seat 11, users can replace or clean them as needed, and there is no need to manufacture and purchase two independent and complete components separately, which not only saves space, but also may reduce production costs to a certain extent.

[0053] In an embodiment in which the switch valve 13 controls the communication and blocking between the water inlet 112 and the water outlet 113, refer to Figure 2 and Figure 3As shown, the mounting base 11 is provided with a valve cavity 114 between the water inlet 112 and the water outlet 113, and the valve cavity 114 is provided with a cavity opening 115 which is communicated with the accommodating cavity 110; the on-off valve 13 comprises a valve core 131 and a spring 132, the valve core 131 is movably arranged in the valve cavity 114 and is used for controlling the communication and blockage between the water inlet 112 and the water outlet 113, i.e. opening or closing the communication between the water inlet 112 and the water outlet 113, and the spring 132 is arranged in the valve cavity 114 and is configured to drive the valve core 131 to move towards the cavity opening 115; the descaling box 16 is provided with a space-providing recess 120, when the descaling box 16 is fixed in the accommodating cavity 110, the valve core 131 is driven by the spring 132 to pass through the cavity opening 115 and extend into the space-providing recess 120 so as to communicate the water inlet 112 and the water outlet 113; when the descaling box 16 is fixed in the accommodating cavity 110, the valve core 131 is pressed by the descaling box 17 to be between the water inlet 112 and the water outlet 113 so as to block the water inlet 112 and the water outlet 113. In this embodiment, the on-off valve 13 can not only control the communication and blockage between the water inlet 112 and the water outlet 113, but also the control operation can be automatically and adaptively performed according to the installation of the descaling box 16 and the descaling box 17, i.e. when the descaling box 16 is installed in the accommodating cavity 110, the space-providing recess 120 can provide space for the valve core 131, the valve core 131 is automatically opened by the spring 132 to make the water inlet 112 and the water outlet 113 communicated, and when the descaling box 17 is installed in the accommodating cavity 110, the descaling box 17 presses the valve core 131 against the spring 132 to make the water inlet 112 and the water outlet 113 automatically blocked, and the water flow of the water inlet 112 can enter the descaling box 17 for filtration.

[0054] For example, referring to Figure 1 and Figure 2 As shown, in order to facilitate the installation of the valve core 131 and the spring 132, the mounting base 11 is provided with a port at one end of the valve cavity 114 which is away from the cavity opening 115, and the port is provided with a cover 133 which is used for sealing the port, one end of the spring 132 is abutted against the inner side of the cover 133, and the other end is abutted against the valve core 131. During installation, the valve core 131 and the spring 132 are sequentially arranged in the valve cavity 114, and then the cover 133 is used to seal the port, so that the spring 132 is compressed to drive the valve core 131 to move towards the cavity opening 115. The cover 133 can be connected with the port by buckling or screwing, and a sealing ring is arranged between the cover 133 and the port to realize the sealing of the port and avoid the water flow from the port.

[0055] In order to limit the maximum moving stroke of the valve core 131 towards the cavity opening 115, referring to Figure 2 As shown, the valve core 131 is provided with a shaft shoulder structure, and when the descaling box 16 is fixed in the accommodating cavity 110, the shaft shoulder is abutted against the edge of the cavity opening 115, so as to limit the valve core 131 from continuously moving towards the cavity opening 115.

[0056] It can be understood that the valve core 131 and the spring 132 can also be loaded into the valve cavity 114 from the cavity opening 115, at this time, the mounting seat 11 at the end of the valve cavity 114 away from the cavity opening 115 can be a sealing structure integrally formed with the mounting seat 11.

[0057] In another embodiment (not shown in the figure) in which the communication and blockage between the water inlet 112 and the water outlet 113 are controlled by the on-off valve 13, the on-off valve 13 is an electronic valve and is provided with a control button, which is triggered by the descaling box 16 and the scale blocking box 17 to control the opening and closing of the on-off valve 13. For example, when the descaling box 16 is fixed in the container cavity 110, the descaling box 16 presses and triggers the control button to make the on-off valve 13 open, and the communication between the water inlet 112 and the water outlet 113 is realized; when the scale blocking box 17 is fixed in the container cavity 110, the scale blocking box 17 cannot trigger the control button, and the on-off valve 13 remains closed, and the water inlet 112 and the water outlet 113 are blocked.

[0058] In order to realize quick positioning with the mounting seat 11 when the descaling box 16 and the scale blocking box 17 are loaded into the container cavity 110, referring to Figure 1 As shown in the figure, the descaling box 16 and the scale blocking box 17 are provided with guide ribs 106 extending in the length direction on the outer side, and the inner side of the mounting seat 11 is provided with guide grooves 116 matched with the guide ribs 106; when the descaling box 16 or the scale blocking box 17 is fixed in the container cavity 110, the guide ribs 106 are located in the guide grooves 116, and the descaling box 16 or the scale blocking box 17 is fixed circumferentially with the mounting seat 11 to make the liquid outlet hole 103 opposite and communicate with the water outlet 113, or the inlet 104 opposite and communicate with the water inlet 112, or the outlet 105 opposite and communicate with the water outlet 113. In this way, when the descaling box 16 and the scale blocking box 17 are installed, only the guide ribs 106 located in the guide grooves 116 are needed, and the cooperation of the guide ribs 106 and the guide grooves 116 plays a foolproof role.

[0059] It can be understood that the descaling box 16 and the scale blocking box 17 can also be quickly positioned with the mounting seat 11 by using marking lines. For example, the descaling box 16 and the scale blocking box 17 are provided with marking lines on the top when installed with the mounting seat 11, and when the marking lines of the descaling box 16 and the scale blocking box 17 are opposite to the marking lines of the mounting seat 11, the liquid outlet hole 103 is opposite and communicates with the water outlet 113, or the inlet 104 is opposite and communicates with the water inlet 112, or the outlet 105 is opposite and communicates with the water outlet 113.

[0060] In one embodiment of the above-mentioned container cavity 110 detachably fixed with the descaling box 16 or the scale blocking box 17, referring to Figures 1 to 3As shown, the switchable scale cleaning mechanism further comprises a rotating cover 14, the top of the mounting seat 11 is open, when the descaling box 16 or the scale inhibition box 17 is loaded and fixed in the container cavity 110 at the top of the mounting seat 11, the rotating cover 14 is connected with the mounting seat 11 through the rotating buckle 141 to be fixed relative to the mounting seat 11, and the rotating cover 14 is pressed on the descaling box 16 or the scale inhibition box 17 to fix the relative position of the descaling box 16 or the scale inhibition box 17 and the mounting seat 11. When the descaling box 16 or the scale inhibition box 17 is disassembled, the rotating cover 14 is only turned in the reverse direction to make the rotating buckle 141 disengage, so that the container cavity 110 is opened and the descaling box 16 or the scale inhibition box 17 is taken out.

[0061] For example, referring to Figure 1 As shown, the rotating cover 14 and the descaling box 16 are connected through the strong buckle 142 to improve the connection firmness.

[0062] The rotating cover 14 can also be connected with the mounting seat 11 through screw connection or tight connection, so that it can be fixed relative to the mounting seat 11 and opened when the descaling box 16 or the scale inhibition box 17 is disassembled.

[0063] In other embodiments in which the container cavity 110 is detachably fixed with the descaling box 16 or the scale inhibition box 17, the descaling box 16 and the scale inhibition box 17 are directly connected with the mounting seat 11 through screw connection or buckle connection, and an end cover is arranged at the top to seal the container cavity 110 when connected.

[0064] In order to facilitate the addition of descaling liquid into the descaling box 16, referring to Figure 1 As shown, the descaling box 16 is provided with an opening, and a sealing cover 107 is arranged at the opening to prevent the descaling liquid from leaking out.

[0065] In the first embodiment in which the descaling liquid in the descaling box 16 flows from the liquid outlet hole 103 to the water outlet 113 under the action of air pressure or water pressure, referring to Figure 2 As shown, the sealing cover 107 is provided with a one-way air inlet valve 108 for delivering air pressure to the inside of the descaling box 16, and the rotating cover 14 is provided with an air inlet hole 143 for delivering air pressure to the one-way air inlet valve 108; the water flow cross section of the water outlet 113 at the communication part along the water flow direction first decreases and then increases. When the descaling box 16 is fixed in the container cavity 110, in the initial state, the descaling liquid cannot or can only flow out in a small amount from the liquid outlet hole 103 due to insufficient pressure; when the water flow flows from the water inlet 112 to the water outlet 113 and the water flow passes through the communication part along the water flow direction where the water flow cross section first decreases and then increases, the descaling liquid in the descaling box 16 is sucked into the water outlet 113 under the action of Bernoulli's principle, mixed with the water flow, thereby playing a role in purifying scale and dirt. Subsequently, the one-way air inlet valve 108 sucks in air to balance the air pressure inside the descaling box 16.

[0066] In the second embodiment in which the descaling liquid in the descaling box 16 flows from the liquid outlet hole 103 to the water outlet 113 under the action of air pressure or water pressure, refer to Figure 4 and Figure 5 shown in the figures, Figure 4 is a schematic diagram of the switching type descaling mechanism of the present application through air pump air supplement, Figure 5 is a perspective view of the switching type descaling mechanism of the present application through air pump air supplement. The mounting seat 11 is provided with an air supplement hole 117, and the descaling box 16 is provided with a one-way valve 109 for delivering air pressure to the inside of the descaling box 16; when the descaling box 16 is fixed in the container cavity 110, the air supplement hole 117 communicates with the one-way valve 109, and air pressure is pumped into the one-way valve 109 through the air pump 18, and the descaling liquid in the descaling box 16 flows from the liquid outlet hole 103 to the water outlet 113 under the action of air pressure.
