[0087] The water-air integrated diaphragm pump and the oral care device having the same according to embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0088] Referring to Figures 1 to 7 As shown, the water-air integrated diaphragm pump according to embodiments of the present application comprises a pump base 10, a liquid delivery hose 20, a roller assembly 30, a diaphragm pump head 40 and a driving mechanism 50.

[0089] Specifically, the pump base 10 can generally be configured as a cylindrical structure, and an accommodating space for mounting components such as the liquid delivery hose 20, the roller assembly 30 and the driving mechanism 50 is formed inside the pump base 10.

[0090] The liquid delivery hose 20 has a liquid inlet end 201 and a liquid outlet end 202, and the liquid delivery hose 20 is located inside the pump base 10, and the liquid inlet end 201 and the liquid outlet end 202 are located outside the pump base 10. Preferably, the liquid delivery hose 20 is wrapped around the axis of the pump base 10 inside the pump base 10, and the liquid delivery hose 20 is in close contact with the inner wall of the pump base 10. Two holes are provided on the peripheral wall of the pump base 10, and the liquid inlet end 201 and the liquid outlet end 202 extend from the two holes to the outside of the pump base 10, so as to be connected with a water supply device and a water outlet device in application.

[0091] The roller assembly 30 is arranged inside the pump base 10 and can roll and press the liquid delivery hose 20 when rotating, so as to transport the liquid in the liquid delivery hose 20 from the liquid inlet end 201 to the liquid outlet end 202. Preferably, the roller assembly 30 can rotate around the axis of the pump base 10, and during the rotation of the roller assembly 30, the roller assembly 30 can roll and press the liquid delivery hose 20, thereby transporting the liquid in the liquid delivery hose 20 from the liquid inlet end 201 to the liquid outlet end 202.

[0092] The diaphragm pump head 40 is arranged on the top of the pump base 10 and is used for pumping gas. The driving mechanism 50 is arranged on the pump base 10 and is used for driving the roller assembly 30 and the diaphragm pump head 40 to work so as to simultaneously supply liquid and gas. That is, when the driving mechanism 50 works, the roller assembly 30 can be driven to rotate at the same time when the diaphragm pump head 40 works. The diaphragm pump head 40 works to pump gas, and the roller assembly 30 rotates to pump liquid.

[0093] It should be noted that in the related art, the diaphragm pump usually only has a single function of pumping gas and cannot realize simultaneous pumping of gas and liquid. In the application scenario in which liquid and gas need to be pumped simultaneously, a liquid pump and a gas pump are usually combined to realize.

[0094] According to the water-gas integrated diaphragm pump provided in the embodiment of the present application, the roller assembly 30 and the liquid supply hose 20 are arranged in the diaphragm pump, and the driving mechanism 50 is used for synchronously driving the diaphragm pump head 40 and the roller assembly 30. On the one hand, the diaphragm pump head 40 works to pump gas. On the other hand, when the roller assembly 30 rotates, the liquid supply hose 20 is rolled and pressed to pump liquid. Therefore, the dual functions of pumping liquid and gas can be realized on one pump, the need for gas mixing is met, the size of the product can be greatly reduced when the product is applied to a specific product, the cost is reduced, in addition, the power consumption is lower, the use time is longer, and the product performance is more superior.

[0095] Referring to FIGS. 1 to 4, Figure 3 and Figures 6 to 7 In one embodiment of the present application, the roller assembly 30 includes a rotating support 301 and at least two rollers 302. The rotating support 301 is arranged in the pump base 10 and is pivotable about a vertical axis, which is preferably the axis of the pump base 10. The at least two rollers 302 are arranged in a circumferential direction of the vertical axis and are parallel to the vertical axis. Exemplarily, the rollers 302 are two, and the two rollers 302 are symmetrically arranged about the vertical axis. It can be understood that the rollers 302 can also be three or more.

[0096] That is, in the embodiment, the roller assembly 30 mainly includes the rotating support 301 and the rollers 302. The rotating support 301 is pivotably mounted in the pump base 10. The rotating support 301 is driven by the driving mechanism 50 to rotate about the vertical axis. The rollers 302 are pivotably mounted on the rotating support 301. On the one hand, the rollers 302 can revolve about the vertical axis with the rotating support 301. On the other hand, the rollers 302 can rotate about their own axes.

[0097] Preferably, when the roller 302 is mounted on the rotating support 301, the wheel surface of the roller 302 has a predetermined gap with the inner wall of the pump base 10, the liquid delivery hose 20 is just located in the predetermined gap, and the predetermined gap is smaller than the diameter of the liquid delivery hose 20, so that the wheel surface of the roller 302 is pressed on the liquid delivery hose 20, and the pressed part of the liquid delivery hose 20 is flattened.

[0098] In the specific working process, the driving mechanism 50 drives the rotating support 301 to rotate around the vertical axis, at this time, the roller 302 rotates with the rotating support 301 and rolls on the liquid delivery hose 20 along the extension direction of the liquid delivery hose 20, thereby realizing the delivery of the liquid in the liquid delivery hose 20 from the liquid inlet end 201 to the liquid outlet end 202. In this way, the peristaltic pumping structure can ensure stable delivery of the liquid, has high repeat precision and stability precision, and the liquid does not contact other components, and is especially suitable for clean care products. In addition, the overall structure is simple, and after being combined with the diaphragm pump head 40, the water-gas integrated diaphragm pump body does not have a significant increase in volume, and has a significant advantage in size.

[0099] Referring to Figures 6 to 7 In some embodiments of the present application, the roller assembly 30 further includes a ring gear 305, a sun gear 303 and planet gears, the ring gear 305 is fixed in the pump base 10, the sun gear 303 is connected with the driving mechanism 50 and coaxially arranged with the rotating support 301. The planet gears are arranged on the rotating support 301 and can be pivoted around their own axes, and the planet gears are respectively engaged with the sun gear 303 and the ring gear 305, so as to drive the rotating support 301 to rotate around the vertical axis through the planet gears.

[0100] When the driving mechanism 50 drives the sun gear 303 to rotate, the sun gear 303 can drive the planet gears to rotate, and the planet gears are in close contact with the ring gear 305, which is fixed in the pump base 10. Therefore, the planet gears can revolve around the axis of the ring gear 305. Since the planet gears are mounted on the rotating support 301, the planet gears can drive the rotating support 301 to rotate around the vertical axis when revolving, and the roller 302 on the rotating support 301 rotates accordingly, thereby rolling on the liquid delivery hose 20 to achieve the purpose of liquid delivery.

[0101] In the present embodiment, the ring gear 305, the sun gear 303 and the planet gears are used to form a planetary gear 304 mechanism, which is used to drive the rotating support 301 to rotate around the vertical axis. On the one hand, the planetary gear 304 mechanism can act as a speed reducer to realize stable driving of the rotating support, and on the other hand, the structure is simple and compact, which is convenient to install in the limited space in the pump base 10, and the load is distributed to a large number of teeth, so that the strength is large and the service life is long.

[0102] Referring to Figure 7As shown, in one embodiment of the present invention, the rotating support 301 includes a central column 301a, a first support plate 301b, and a second support plate 301c. The axis of the central column 301a serves as the vertical axis. The first support plate is connected to the upper end of the central column 301a, and the second support plate is connected to the lower end of the central column 301a. A roller 302 is pivotally disposed between the first support plate 301b and the second support plate 301c, and the planetary gear 304 is pivotally disposed on either the first support plate 301b or the second support plate 301c.

[0103] In this embodiment, the rotating support 301 mainly consists of a central column 301a, a first support plate 301b, and a second support plate 301c. The first support plate 301b and the second support plate 301c are connected to the upper and lower ends of the central column 301a. Preferably, the first support plate 301b and the second support plate 301c are connected to form an "I"-shaped rotating support 301. Two rollers 302 are symmetrically arranged on the "I"-shaped rotating support 301. A sun gear 303 is installed below the second support plate 301c and coaxial with the central column 301a. Two planetary gears 304 are installed below the second support plate 301c and coaxial with the two rollers 302. Using the above-described rotating support 301 structure, it can be ensured that multiple rollers 302 can rotate around the vertical axis, continuously pulse-squeezing the liquid delivery hose 20 to achieve a stable and reliable pumping effect. Furthermore, it can form a relatively balanced structure, ensuring stable operation and a long service life.

[0104] Reference Figures 2 to 6 As shown, in some embodiments of the present invention, the diaphragm pump head 40 includes a diaphragm member 401 disposed on the top of the pump base 10, and the diaphragm member 401 has at least two cups 401a.

[0105] The drive mechanism 50 includes a swing frame 501, an eccentric drive assembly, and a drive motor 504. The swing frame 501 is connected to the diaphragm member 401, the eccentric drive assembly is connected to the swing frame 501, and the drive motor 504 is connected to the sun gear 303 and the eccentric drive assembly.

[0106] During operation, the driving motor 504 drives the eccentric driving assembly to rotate, which drives the swing frame 501 to swing circumferentially and reciprocally, thereby compressing or stretching the rubber bowl 401a. When the rubber bowl 401a is stretched, the suction action is completed, and when the rubber bowl 401a is compressed, the exhaust action is completed. In this way, the suction action and the exhaust action are alternately and continuously formed, so that the gas is pumped. In addition, the driving motor 504 drives the eccentric driving assembly to rotate, which drives the sun gear 303 to rotate, the sun gear 303 drives the planetary gear 304 to rotate, the planetary gear 304 further drives the rotating support 301 to rotate, and the roller 302 on the rotating support 301 rolls and presses the liquid conveying hose 20, so that the liquid is pumped.

[0107] In the embodiment, the driving motor 504 is directly connected to the sun gear 303 and the eccentric driving assembly, so that the gas and liquid pumping can be synchronously performed, and the synchronization effect is better.

[0108] It can be understood that the eccentric driving assembly generally includes an eccentric wheel 502 and an inclined pin 503. The eccentric wheel 502 is provided with an eccentric inclined hole, the lower end of the inclined pin 503 is inserted into the inclined hole, the upper end of the inclined pin 503 is coaxially connected with the swing frame, and the driving motor 504 is connected with the eccentric wheel 502. When the driving motor 504 drives the eccentric wheel 502 to rotate, the eccentric wheel 502 drives the inclined pin 503, the inclined pin 503 drives the swing frame 501 to swing circumferentially, thereby compressing or stretching the rubber bowl 401a, realizing the suction and exhaust, and completing the gas pumping.

[0109] Referring to Figure 3 In one embodiment of the present application, the pump base 10 has a first cavity P10a and a second cavity P10b. The first cavity P10a is located below the second cavity P10b. The roller assembly 30 and the liquid conveying hose 20 are located in the first cavity P10a. The swing frame 501 and the eccentric driving assembly are arranged in the second cavity P10b. The driving motor 504 is arranged at the bottom of the pump base 10, and the driving shaft of the driving motor 504 extends upward from the first cavity P10a to the second cavity P10b.

[0110] That is, the first cavity P10a and the second cavity P10b are arranged in a top-bottom manner, and the roller assembly 30 is arranged in the first cavity P10a, and the swing frame 501 and the eccentric drive assembly are arranged in the second cavity P10b, and the drive motor 504 can be arranged in a vertical manner, and the drive shaft of the drive motor 504 extends from the first cavity P10a to the second cavity P10b, and is connected with the sun gear 303 in the first cavity P10a and the eccentric drive assembly in the second cavity P10b, respectively. In this way, the arrangement relationship is compact in structure and small in size, and the drive motor 504 can stably and reliably drive the sun gear 303 and the eccentric drive assembly to move synchronously.

[0111] Exemplarily, the pump base 10 comprises a base 101, an intermediate seat 102 and a top seat 103, the drive motor 504 is installed at the bottom of the base 101, the intermediate seat 102 is detachably connected with the base 101, for example, buckling connection, and the top seat 103 is fixedly connected with the intermediate seat 102, for example, the three are fixedly connected together by means of screws penetrating through the diaphragm pump head 40, the top seat 103 and the intermediate seat 102. By adopting this split structure, the assembly of various components is facilitated.

[0112] Referring to Figures 4 to 5 In an embodiment of the present application, the diaphragm pump head 40 further comprises a valve plate 402, a pump head cover 403 and a normally closed check valve 404. The valve plate 402 is arranged on the diaphragm pump body and seals the leather cup 401a. The pump head cover 403 is arranged above the valve plate 402 and defines a gas chamber P40 with the valve plate 402. The pump head cover 403 is provided with an exhaust port H4a.

[0113] The normally closed check valve 404 is arranged on the valve plate 402 to control the one-way entry of the gas in the leather cup 401a into the gas chamber P40. When the swing frame 501 drives the diaphragm 401, the leather cup 401a alternately generates a gas suction action and a gas exhaust action, so that the leather cup 401a first sucks in the gas and then exhausts the gas into the gas chamber P40 through the normally closed check valve 404. Exemplarily, the normally closed check valve 404 is an umbrella valve, which is installed on the valve plate 402. The valve plate 402 is provided with a plurality of valve holes H40, which are arranged at intervals around the axis of the umbrella valve, and the inner umbrella surface of the umbrella valve abuts against the top surface of the valve plate 402 to seal each valve hole H40. When the leather cup 401a is compressed and the air pressure of the valve hole H40 increases, the umbrella valve is forced to deform upward to open the valve hole H40.

[0114] The swing frame 501 has at least two connecting portions 501a, the at least two connecting portions 501a correspond to the at least two rubber cups 401a one by one, each connecting portion 501a is arranged at the bottom of the corresponding rubber cup 401a, and the bottom of the rubber cup 401a is provided with a one-way valve piece 4011. The connecting portion 501a is provided with a suction hole H50, when the rubber cup 401a is converted from the compressed state to the elongated state, the negative pressure in the rubber cup 401a forces the one-way valve piece 4011 to deform upwards to open the suction hole H50, and the gas is sucked through the suction hole H50.
