Description

Technical Field

[0001] This utility model relates to the field of sanitary ware technology, and in particular to a pump liquid structure and a toilet. Background Technology

[0002] Most smart toilets equipped with foam shields currently use foaming devices to generate foam that covers the water surface of the toilet bowl, achieving good splash prevention, odor isolation, wall lubrication, and sterilization effects. The working principle of the foam shield mainly involves mixing a foaming agent with water in a certain proportion, and then mixing it with air using a pump to generate foam. During the mixing stage, electronic pumps such as diaphragm pumps or peristaltic pumps are often used to extract and add the foaming agent. However, toilets are often used in humid environments, and long-term use of electronic pumps carries the risk of rust, component corrosion, and electrical aging and malfunction. Furthermore, due to the structural characteristics of electronic pumps, their operation is also affected by the fluidity of the medium, causing deviations in the pump volume and impacting the operating effect.

[0003] Existing technologies also include structures for mechanically extracting and adding foaming agents. However, these typically involve pumping the liquid during the water initiation phase and pumping it out during the water shut-off phase. Pumping the liquid during the water initiation phase not only prevents the foaming agent from being fully mixed with the water before being carried away by the flowing water for the next foaming step, leading to problems such as uneven mixture concentration, waste of foaming agent, and poor foaming effect, but also results in the pump outlet often being connected to the mixing chamber, and the water outlet also being connected to the mixing chamber. When both enter the mixing chamber simultaneously, it causes pressure dispersion in the chamber, i.e., pressure resistance between them, resulting in back pressure pumping, making pumping difficult and the pumping volume uncontrollable.

[0004] Therefore, how to replace electronic pumps with simple, compact, and low-cost mechanical structures to avoid the impact of the environment on the operation process, reduce the failure rate, and achieve the effect of pumping liquid during the start-up stage and pumping liquid during the end stage, so that the pumping volume is accurately controllable and can be pre-mixed to avoid the influence of the flow of foaming agents and other media on the mixing effect and improve consistency are problems that need to be solved by people in this field. Utility Model Content

[0005] The purpose of this utility model is to provide a pump structure and toilet that replaces the electronic pump with a simple, compact, and low-cost mechanical structure, avoids the impact of the environment on the operation process, reduces the failure rate, and achieves the effect of pumping liquid during the start-up stage and pumping liquid during the end stage. This makes the pump volume precise and controllable, and allows for pre-mixing, avoiding the influence of foaming agents and other media on the mixing effect and improving consistency.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] The pump fluid structure includes:

[0008] The pump body and the movable component are movably disposed in the pump body along a first direction. The pump liquid structure has at least a water inlet state and a liquid outlet state. In the water inlet state, water enters the pump body and pushes the movable component to move so as to draw foaming agent into the pump body. In the liquid outlet state, the movable component moves in the pump body and the foaming agent can be discharged from the pump body.

[0009] Optionally, the pump body includes a premixing chamber, and a pressure-changing chamber and a pump fluid chamber connected to the premixing chamber.

[0010] In this water-inlet state, water enters the pressure-transforming chamber and pushes the movable component to move upward along the first direction before entering the premixing chamber. The volume of the pump liquid chamber increases and draws in the foaming agent.

[0011] In this liquid discharge state, the movable component moves downward along the first direction, the volume of the pump liquid chamber decreases, the foaming agent is squeezed into the premix chamber, mixed with water, and then discharged from the pump body.

[0012] Optionally, the pump body is provided with a pressure-transforming port, which is connected to the pressure-transforming chamber and the premixing chamber respectively.

[0013] Optionally, the pump body is provided with a water inlet, and the water inlet has a water inlet channel communicating with the transformer chamber, and / or,

[0014] The pump body is provided with a liquid outlet, which is connected to the pump liquid chamber and the premixing chamber respectively.

[0015] Alternatively, the diameter of the transformer orifice may be smaller than the inner diameter of the water inlet channel.

[0016] Optionally, the pump body is provided with a first valve and a second valve, the first valve being used to control the foaming agent to enter the pump liquid chamber, and the second valve being used to control the foaming agent to enter the premixing chamber.

[0017] Optionally, both the first valve and the second valve may be configured as check valves.

[0018] Optionally, it also includes a pump cover that covers the top of the pump body, and the movable component can extend out of the pump cover.

[0019] Alternatively, the movable component includes a movable plug and an elastic element, the elastic element being sleeved outside the movable plug, the movable plug being movable within the pump body along the first direction.

[0020] On the other hand, a toilet includes the pump structure, a power unit connected to the pump structure, a reservoir and a lower mixing chamber, the power unit for injecting water, the reservoir for storing the foaming agent, and the foaming agent mixed with water in the pump structure and discharged into the lower mixing chamber.

[0021] The beneficial effects of this utility model are:

[0022] In this invention, the pump structure has an inlet and an outlet state. In the inlet state, water drives the movable component to draw in the foaming agent, achieving the effect of pumping liquid during the start-up phase. Furthermore, in the outlet state, the movable component moves to discharge the foaming agent from the pump body, achieving the effect of pumping liquid under pressure during the end phase. Simultaneously, discharging the foaming agent from the pump body facilitates thorough mixing in the next step, thereby improving the consistency of the mixture. Specifically, the inlet and outlet of the foaming agent are achieved by the up-and-down movement of the movable component, thus replacing the electronic pump with a mechanical structure, avoiding the influence of the environment on the pump structure, and reducing the failure rate.

[0040] The technical solution of this embodiment will be further described below with reference to the accompanying drawings and specific implementation methods.

[0041] like Figures 1-3 As shown, this embodiment provides a pump structure 100, including a pump body 10, a pump cover 20, a movable component 30, and a water outlet 40. Optionally, the pump cover 20 is disposed on the top of the pump body 10, the movable component 30 is movably disposed in the pump body 10 along a first direction, and the movable component 30 can extend out of the pump cover 20, while the water outlet 40 is connected to the pump body 10 for discharging the mixed liquid. Specifically, in this embodiment, the pump liquid structure 100 has at least a water inlet state and a liquid outlet state. In the water inlet state, water enters the pump body 10 and pushes the movable component 30 upward along the first direction, allowing the foaming agent to be drawn into the pump body 10 for pre-storage. In the liquid outlet state, water is no longer injected into the pump body 10, and the movable component 30 can move downward along the first direction within the pump body 10 to return to its initial position. At this time, the pre-storage foaming agent can be mixed with water and then discharged from the pump body 10 for use. Thus, the foaming agent can be mechanically accessed, and liquid can be pumped when water injection begins and pumped after water injection ends. This allows for precise control of the pump liquid volume through forward pressure pumping, and also achieves a pre-mixing effect to avoid the influence of the flowability of the foaming agent and other media, resulting in better consistency. In other embodiments, the foaming agent can also be directly discharged from the pump body 10 in the liquid outlet state to ensure foaming requirements. Whether pre-mixing is performed can be set as needed and is not limited here.

[0042] like Figure 4 and Figure 5 As shown, in this embodiment, the pump body 10 is provided with a pressure-changing chamber 101, a premixing chamber 103, and a pumping chamber 104. Optionally, both the pressure-changing chamber 101 and the pumping chamber 104 are connected to the premixing chamber 103, and the movable component 30 separates the pressure-changing chamber 101 from the pumping chamber 104. Figures 6-8 As shown, specifically, in the water-inlet state, water enters the pressure-changing chamber 101 and can push the movable component 30 upward along the first direction, thereby increasing the volume of the pump liquid chamber 104 and drawing the foaming agent into the pump liquid chamber 104 for pre-storage. Simultaneously, water can flow from the pressure-changing chamber 101 to the premixing chamber 103 for pre-storage. Combined with... Figure 9 As shown, correspondingly, in the liquid discharge state, water is no longer injected into the pressure-transforming chamber 101, and the movable component 30 will move downward along the first direction until the initial position. At this time, the volume of the pumping chamber 104 becomes smaller, and the foaming agent can be squeezed into the premixing chamber 103 to achieve a mixture of foaming agent and water. The mixture is then discharged from the pump body 10 to complete the pumping.

[0043] like Figure 5 As shown, the pump body 10 is provided with a water inlet 11, and the water inlet 11 is provided with a water inlet channel 111 communicating with the transformer chamber 101, thereby ensuring smooth water inflow. Combined with... Figure 8As shown, the transformer cavity 101 is configured as an annular cavity and is arranged around the outside of the movable component 30. For example... Figure 4 As shown, the pump body 10 is further provided with a pressure-changing hole 102, and the pressure-changing hole 102 is connected to the pressure-changing chamber 101 and the premixing chamber 103 respectively. Thus, after the water enters the pressure-changing chamber 101 through the water inlet channel 111, it can enter the premixing chamber 103 through the pressure-changing hole 102.

[0044] Specifically, the diameter of the pressure-changing hole 102 is smaller than the inner diameter of the water inlet channel 111. Therefore, in the water-inlet state, the pressure inside the pressure-changing chamber 101 increases, which in turn pushes the movable component 30 upward along the first direction. This causes the volume of the pumping chamber 104 below the movable component 30 to increase, creating a negative pressure, which in turn draws the foaming agent into the pumping chamber 104. Correspondingly, in the liquid-outlet state, the water inlet 11 is closed, allowing water in the pressure-changing chamber 101 to gradually enter the premixing chamber 103 through the pressure-changing hole 102. This releases the pressure inside the pressure-changing chamber 101. After losing the force of the water, the movable component 30 moves downward along the first direction until it returns to its initial position, thereby squeezing the pumping chamber 104, reducing its volume, and gradually squeezing the foaming agent into the premixing chamber 103. The foaming agent then premixes and dilutes with the water coming out of the pressure-changing hole 102 in the premixing chamber 103.

[0045] like Figure 4 As shown, specifically, the pump body 10 is provided with a first valve 13 and a second valve 14, and has a liquid outlet 141. Optionally, the first valve 13 is located below the movable component 30 and is used to control the foaming agent entering the pump liquid chamber 104, while the second valve 14 is located at the premixing chamber 103 and is used to control the foaming agent in the pump liquid chamber 104 to enter the premixing chamber 103. Exemplarily, both the first valve 13 and the second valve 14 are configured as one-way valves, and the first valve 13 only allows the foaming agent to enter the pump liquid chamber 104 from the outside, while the second valve 14 only allows the foaming agent to enter the premixing chamber 103 from the pump liquid chamber 104, thereby preventing the foaming agent from flowing backward and affecting the mixing effect.

[0046] Specifically, the water inlet 11 is provided with a water inlet channel 111 communicating with the transformer chamber 101, and / or, the liquid outlet 141 is respectively connected to the pump chamber 104 and the premixing chamber 103. Optionally, the foaming agent in the pump chamber 104 enters the second valve 14 through the liquid outlet 141, and then enters the premixing chamber 103 under the action of the second valve 14. Figure 5As shown, the pump body 10 further includes a liquid inlet 12 at its bottom, and the liquid inlet 12 has a liquid inlet channel 121 connected to the first valve 13. This allows the foaming agent to be delivered to the first valve 13 via the liquid inlet channel 121, and then, under the action of the first valve 13, the foaming agent can enter the pump liquid chamber 104. Exemplarily, in this embodiment, both the water inlet 11 and the liquid inlet 12 are arranged along the second direction to facilitate separate liquid injection.

[0047] Combination Figures 4-9 As shown, in this embodiment, a limiting protrusion 21 is provided inside the pump cover 20, and a limiting boss 15 is provided inside the pump body 10. Specifically, the movable component 30 is limited between the limiting protrusion 21 and the limiting boss 15, thereby limiting the range of movement of the movable component 30 in the first direction, and thus limiting the space of the pump liquid chamber 104, so as to achieve precise control of the amount of foaming agent absorbed.

[0048] Specifically, the movable component 30 includes a movable plug 31 and an elastic member 32, and the movable plug 31 is provided with a first abutment end 311 and a second abutment end 312. Optionally, the elastic member 32 is configured as a spring and sleeved on the outside of the movable plug 31, allowing the movable plug 31 to move up and down in a first direction within the pump body 10. Exemplarily, a receiving groove is provided on the outside of the movable plug 31, the bottom end of the elastic member 32 is disposed at the bottom of the receiving groove, and the top end of the elastic member 32 is confined within the pump cover 20. Figure 6 and Figure 7 As shown, specifically, the pump cover 20 is provided with a movable opening, and the movable plug 31 is movably disposed in the movable opening so that it can extend out of the pump cover 20 when water is in the inlet state.

[0049] Furthermore, the top of the receiving groove of the movable plug 31 is provided with a first abutting end 311, which can abut against the limiting protrusion 21 to achieve the upper limit of the movable plug 31. Correspondingly, the bottom outer side of the receiving groove of the movable plug 31 is provided with a second abutting end 312, which can abut against the limiting protrusion 15 to achieve the lower limit of the movable plug 31.

[0050] Optionally, the water outlet 40 is arranged along a third direction and connected to the end of the pump body 10 where the premixing chamber 103 is provided. Specifically, the water outlet 40 is provided with a water outlet channel 401, and the water outlet channel 401 is connected to the premixing chamber 103. Thus, water entering the premixing chamber 103 through the pressure transformer 102 in the water inlet state can flow out through the water outlet channel 401, and the mixture of foaming agent and water introduced into the premixing chamber 103 by the second valve 14 in the liquid outlet state can also flow out through the water outlet channel 401. Exemplarily, in this embodiment, the first direction, the second direction, and the third direction are arranged at an angle, with the first direction arranged along the axis of the pump body 10 and the movable component 30, and the third direction arranged along the axis of the water outlet 40. Preferably, each of the first direction, the second direction, and the third direction is perpendicular to the others.

[0051] Optionally, sealing rings are provided between the outer side of the movable plug 31 and the inner wall of the pressure-transforming chamber 101, and between the outer side of the movable plug 31 and the inner wall of the pump liquid chamber 104, to prevent leakage. Correspondingly, sealing rings are also provided on the outer sides of the first valve 13 and the second valve 14, and a sealing ring is also provided between the water outlet 40 and the pump body 10 to prevent leakage.

[0052] Work process: such as Figures 6-8 As shown, in the water-inlet state, water with a certain pressure is input into the pressure-transforming chamber 101 through the water inlet channel 111. Under the action of the pressure-transforming hole 102 with a smaller diameter, the pressure in the pressure-transforming chamber 101 increases. When the force of the water on the movable plug 31 is greater than the elastic force of the elastic member 32, the movable plug 31 moves upward along the first direction and squeezes the elastic member 32 until the first abutting end 311 abuts against the limiting protrusion 21. The position of the movable plug 31 no longer changes. During the movement of the movable plug 31, the volume of the pump liquid chamber 104 increases and a negative pressure is generated. The foaming agent is drawn into the pump liquid chamber 104 for pre-storage after passing through the liquid inlet channel 121 and the first valve 13.

[0053] like Figure 9 As shown, in the liquid discharge state, the water inlet channel 111 is closed to stop water injection into the pressure transformer chamber 101. Under the action of the pressure transformer hole 102, the pressure in the pressure transformer chamber 101 is gradually released until the force of water on the movable plug 31 is less than the force of the elastic member 32. Then, under the action of the elastic member 32, the movable plug 31 moves downward along the first direction until the second abutting end 312 abuts against the limiting boss 15. The position of the movable plug 31 no longer changes. During this process, the volume of the pump liquid chamber 104 decreases, so that the foaming agent in the pump liquid chamber 104 is squeezed to the second valve 14 through the liquid outlet hole 141 and injected into the premixing chamber 103 under the action of the second valve 14 to achieve the mixing of foaming agent and water. Finally, the mixture flows out through the water outlet channel 401.

[0054] The specific structure of the toilet in this embodiment is described below.

[0055] like Figure 1 As shown, the toilet includes the aforementioned pump structure 100, and a power unit 200, a liquid storage box 300, and a lower-stage mixing chamber 400 connected to the pump structure 100. Optionally, the power unit 200 is connected to the water inlet 11 for filling with water, ensuring a smooth water supply. Further, the liquid storage box 300 is connected to the liquid inlet 12 for storing foaming agent, which can then be drawn into the pump structure 100 through the liquid inlet 12. Correspondingly, the lower-stage mixing chamber 400 is connected to the water outlet 40, whereby the foaming agent and water, after being mixed in the pump structure 100, can be discharged into the lower-stage mixing chamber 400 for thorough mixing.
