Technical Field
[0001] This utility model relates to the field of bathroom product technology, and in particular to a pumping device for toiletries and a foaming device using the same. Background Technology
[0002] In the bathroom product sector, devices capable of electrically pumping out toiletries are already available on the market. However, these devices typically only pump one type of toiletries with a single electric pump. In real-life scenarios, users often require at least two toiletries—shampoo and shower gel—while showering, and may also need to use makeup remover and facial cleanser, or shaving cream and facial cleanser, etc. Using existing toiletries pumping devices would require multiple electric pumps, undoubtedly increasing costs. Therefore, finding a simpler design to pump out two types of toiletries has become a pressing issue. Utility Model Content
[0003] The purpose of this utility model is to provide a pumping device for washing and care products and a foaming device using the same. The technical problem to be solved is how to achieve the pumping of two kinds of washing and care products through a simpler structure.
[0004] To achieve the above objectives, the solution of this utility model is: a pumping device for washing and care products, including a peristaltic pump, a first liquid storage bottle, a second liquid storage bottle, a first check valve, and a second check valve;
[0005] The peristaltic pump has a first pump port and a second pump port. When the peristaltic pump rotates forward, it draws in liquid from the first pump port and pumps it out from the second pump port. When the peristaltic pump rotates in reverse, it draws in liquid from the second pump port and pumps it out from the first pump port.
[0006] The first liquid storage bottle is used to store the first liquid. The first liquid storage bottle and the first pump port are connected by a first one-way valve, so that only the first liquid storage bottle can flow to the first pump port in one direction.
[0007] The second storage bottle is used to store the second liquid. The second storage bottle and the second pump port are connected by a second one-way valve, so that only the second storage bottle can flow to the second pump port in one direction.
[0008] The flow path between the second check valve and the second pump port has a first liquid outlet, and the flow path between the first check valve and the first pump port has a second liquid outlet. The first liquid outlet and the second liquid outlet are used to supply liquid flow.
[0009] Furthermore, the first outlet is connected to a third check valve, which allows liquid to be discharged only from the first outlet into the flow path between the second check valve and the second pump port. The second outlet is connected to a fourth check valve, which allows liquid to be discharged only from the second outlet into the flow path between the first check valve and the first pump port.
[0010] Furthermore, the peristaltic pump includes a pump body, a hose, and a roller assembly;
[0011] The pump body has a containment space;
[0012] The hose is located within the receiving space, with one end of the hose forming the first pump port and the other end forming the second pump port;
[0013] The roller assembly is located within the receiving space. By rolling, the roller assembly compresses and deforms the hose. When rotating in the forward direction, the hose is continuously deformed from the first pump port to the second pump port, so as to push the liquid in the hose near the first pump port to the second pump port. When rotating in the reverse direction, the hose is continuously deformed from the second pump port to the first pump port, so as to push the liquid in the hose near the second pump port to the first pump port.
[0014] A foaming device, using a washing and care product pumping device as described above, further includes a foaming chamber, wherein the first liquid outlet and the second liquid outlet are both connected to the foaming chamber, and the foaming chamber is also connected to an air inlet device for introducing air into the foaming chamber.
[0015] Furthermore, the foaming chamber is also connected to a water supply device, which is used to supply water into the foaming chamber.
[0016] Furthermore, a water flow monitoring device is installed on the pump flow path of the water supply device. The water flow monitoring device is communicatively connected to the peristaltic pump, so that the peristaltic pump can only be turned on when the water flow monitoring device detects that the water supply device is pumping water into the aerating chamber.
[0017] Furthermore, a foaming net is provided inside the foaming chamber.
[0018] Furthermore, the foaming net has multiple layers.
[0019] Furthermore, the foaming chamber has a foam outlet.
[0020] Furthermore, the bubble outlet is connected to the water outlet of the shower head or the water outlet of the faucet.
[0021] After adopting the above solution, the beneficial effects of this utility model are as follows:
[0022] (1) When the peristaltic pump of the washing and care product pumping device rotates forward, it draws in liquid from the first pump port and pumps it out from the second pump port. When the peristaltic pump rotates in reverse, it draws in liquid from the second pump port and pumps it out from the first pump port. The first storage bottle stores the first liquid. The first storage bottle and the first pump port are connected by the first one-way valve, so that only the first storage bottle can flow to the first pump port in one direction. The second storage bottle stores the second liquid. The second storage bottle and the second pump port are connected by the second one-way valve, so that only the second storage bottle can flow to the second pump port in one direction. The flow path between the second one-way valve and the second pump port is provided with a first outlet and a second outlet. Thus, when the peristaltic pump rotates forward, it can pump the first liquid in the first storage bottle out from the first outlet. When the peristaltic pump rotates in reverse, it can pump the second liquid in the second storage bottle out from the second outlet. The pumping of two washing and care products is achieved through a simpler structure.
[0023] (2) The foaming device uses the aforementioned washing and care product pumping device to connect the first liquid outlet and the second liquid outlet to the foaming chamber. The foaming chamber is also connected to an air inlet device, which is used to introduce air into the foaming chamber. By controlling the forward and reverse rotation of the peristaltic pump, the foaming chamber can foam the first liquid and the second liquid respectively, thus achieving foaming of the two washing and care products separately through a simpler structure.

[0028] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0029] Unless otherwise expressly defined, the use of directional terms such as "center," "lateral," "longitudinal," "horizontal," "vertical," "top," "bottom," "inner," "outer," "upper," "lower," "front," "rear," "left," "right," "clockwise," and "counterclockwise" in the claims, description, and accompanying drawings of this invention is merely for the convenience of describing the invention and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the specific scope of protection of this invention.
[0030] A pumping device for toiletries, such as Figure 1-3 As shown, it includes a peristaltic pump 1, a first liquid storage bottle 2, a second liquid storage bottle 3, a first check valve 4, and a second check valve 5;
[0031] The peristaltic pump 1 has a first pump port 6 and a second pump port 7, which is a conventional peristaltic pump structure. It satisfies the following characteristics of existing peristaltic pumps: when the peristaltic pump 1 rotates forward, liquid is drawn in from the first pump port 6 and then pumped out from the second pump port 7; when the peristaltic pump 1 rotates in reverse, liquid is drawn in from the second pump port 7 and then pumped out from the first pump port 6. In this embodiment, the more specific structure of the peristaltic pump 1 is as follows: the peristaltic pump 1 includes a pump body 12, a hose 13, and a roller assembly 14; the pump body 12 has a receiving space 15; the hose 13 is located within the receiving space 15, and one end of the hose 13 forms the first pump port 6. The other end forms the second pump port 7; the roller assembly 14 is located in the receiving space 15 and can be rotated by a motor. The roller assembly 14 rolls and compresses the hose 13 to deform. When rotating in the forward direction, it rolls the hose 13 to continuously deform the hose 13 from the first pump port 6 to the second pump port 7, so as to push the liquid in the hose 13 near the first pump port 6 to the second pump port 7. When rotating in the reverse direction, it rolls the hose 13 to continuously deform the hose 13 from the second pump port 7 to the first pump port 6, so as to push the liquid in the hose 13 near the second pump port 7 to the first pump port 6.
[0032] The first storage bottle 2 stores a first liquid, and the second storage bottle 3 stores a second liquid. The first and second liquids are different personal care products, such as shampoo and shower gel. The first storage bottle 2 and the first pump port 6 are connected by a first one-way valve 4. The structure of the first one-way valve 4 is not limited, as long as it allows only one-way flow from the first storage bottle 2 to the first pump port 6. The second storage bottle 3 and the second pump port 7 are connected by a second one-way valve 5. The structure of the second one-way valve 5 is not limited, as long as it allows only one-way flow from the second storage bottle 3 to the second pump port 7. A first outlet 8 is provided in the flow path between the second one-way valve 5 and the second pump port 7. A second outlet 9 is provided in the flow path between a one-way valve 4 and a first pump port 6. The first outlet 8 and the second outlet 9 are used to supply liquid outflow. Thus, the following working process can be realized: when the peristaltic pump 1 rotates forward, the first liquid in the first storage bottle 3 is drawn into the first pump port 6, and then pumped out from the second pump port 7 into the flow path between the second pump port 7 and the second one-way valve 5. Due to the setting of the second one-way valve 5, the first liquid can only flow out through the first outlet 8 at this time. When the peristaltic pump is turned on to rotate forward, the first liquid is pumped out from the first outlet 8. The principle is the same when the peristaltic pump is reversed, which will not be described in detail. The second liquid is pumped out from the second outlet 9.
[0033] In a preferred embodiment, to prevent backflow at the first outlet 8 and the second outlet 9, the first outlet 8 is connected to a third check valve 10. The third check valve 10 allows liquid to be discharged only from the first outlet 8 into the flow path between the second check valve 5 and the second pump port 7. The second outlet 9 is connected to a fourth check valve 11. The fourth check valve 11 allows liquid to be discharged only from the second outlet 9 into the flow path between the first check valve 4 and the first pump port 6. More specifically, the second pump port 7 and the second check valve 5 are connected via a second three-way valve, and the other port of the second three-way valve is connected to the inlet end of the third check valve 10. The first pump port 6 and the first check valve 4 are connected via a first three-way valve, and the other port of the first three-way valve is connected to the inlet end of the fourth check valve 11.
[0034] A foaming device, employing a washing and care product pumping device as described above, further includes a foaming chamber 16. The first liquid outlet 8 and the second liquid outlet 9 are both connected to the foaming chamber 16. Specifically, in this embodiment, the liquid outlet ends of the third one-way valve 10 and the fourth one-way valve 11 are respectively connected to the foaming chamber 16. The foaming chamber 16 is also connected to an air inlet device 17, which is used to introduce air into the foaming chamber 16. The introduced gas mixes with the first liquid or the second liquid in the foaming chamber 16 to foam the first liquid and the second liquid. The specific structure of the foaming chamber 16 is not limited, and any existing foaming chamber structure for foaming detergents can be used. This allows the first liquid and the second liquid to be foamed separately by controlling the forward and reverse rotation of the peristaltic pump 1. Specifically, in this embodiment, the air inlet device 17 is an electric air pump that pumps air into the foaming chamber 16.
[0035] In order to make the foaming more complete, in a preferred embodiment, the foaming chamber 16 is also connected to a water supply device 18. The water supply device 18 is used to supply water into the foaming chamber 16. Specifically, in this embodiment, the water supply device 18 is a household water supply system, and water is supplied into the foaming chamber 16 by setting an appropriate water flow rate. Based on this, to avoid the problem of poor foaming effect caused by the water supply device 18 not being turned on to supply water to the foaming chamber 16 when the peristaltic pump and air pump are turned on for foaming, resulting in poor foaming effect, a water flow monitoring device 19 is provided on the pump water flow path of the water supply device 18. The water flow monitoring device 19 is communicatively connected to the peristaltic pump 1, so that the peristaltic pump 1 can only be turned on when the water flow monitoring device 19 detects that the water supply device 18 is pumping water to the foaming chamber 16. Of course, those skilled in the art will understand that the communication connection here can be controlled by an MCU or the like, which is a common technical means in the art. Specifically, in this embodiment, the air pump, the water flow monitoring device, and the peristaltic pump are all communicatively connected to an MCU, and the MCU is powered on and connected to two buttons for controlling the forward and reverse rotation of the peristaltic pump. Specifically, in this embodiment, the two buttons are the shower gel button and the shampoo button. Furthermore, the water flow detection device 19 can be any existing structure used to monitor whether water is flowing, such as a flow meter.
[0036] Specifically, in this embodiment, a foaming net is provided in the foaming chamber 16. Preferably, the foaming net is provided with multiple layers. The first liquid or the second liquid entering the foaming chamber 16 passes through each layer of the foaming net in sequence. When passing through the mesh of the foaming net, air and water are mixed in to form bubbles.
[0037] Specifically, in this embodiment, the foaming chamber 16 is provided with a foam outlet, and the first liquid and the second liquid after foaming are discharged from the foam outlet into the foaming chamber 16.
[0038] The aforementioned foaming device can be applied to any bathroom product, such as a showerhead or faucet. For example, when applied to a faucet, the foam outlet is connected to the faucet's water outlet, enabling the faucet's water outlet to spray out cleaning agents such as hand soap foam or facial cleanser foam. When applied to a showerhead, the foam outlet is connected to the showerhead's water outlet, thus enabling the showerhead's water outlet to also have an automatic foaming function. Therefore, during the shower, one can first turn on the water to rinse the body, and then turn on the foaming function to make the showerhead spray out shampoo foam or shower gel foam, and then rinse the body with hot water again, making the shower process more convenient and comfortable.
[0039] The above description is only a preferred embodiment of this utility model and is not intended to limit the design of this case. All equivalent changes made based on the key design of this case shall fall within the protection scope of this case.
