[0042] The exemplary embodiments of the present application are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the present application, and are not intended to exhaust all possible methods of the present application, nor to limit the scope of the present application.

[0043] The present application provides a double-tank water flosser capable of switching liquid sources. Figures 1 to 5 The double-tank oral irrigator may include a solenoid valve 100 , a first water tank 210 , a second water tank 220 , a water guide pipe 300 , and a pump assembly 400 .

[0044] See also Figure 4 , Figure 5The solenoid valve 100 may include an outlet portion 110, a first inlet portion 120, a second inlet portion 130, a valve core 150 and a solenoid coil. By controlling the on and off of the solenoid coil, the valve core 150 can be controlled to move and block the first inlet portion 120 and the second inlet portion 130. The first inlet portion 120 can be connected to the first water tank 210, the second inlet portion 130 can be connected to the second water tank 220, and the outlet portion 110 is connected to one end of the water pipe 300. By controlling the blocking conditions of the first inlet portion 120 and the second inlet portion 130 through the solenoid coil, liquid can be selected in the corresponding water tank to achieve liquid source switching of the water flosser.

[0045] See also Figure 3 The pump assembly 400 may include a pressure chamber 410, which is connected to the other end of the water pipe 300 and the spray port 500 of the water flosser. A nozzle 510 may be provided outside the spray port 500 (see Figure 1 , Figure 2 ).like Figure 3 As shown by the dotted arrow in FIG. 1 , the liquid in the first water tank 210 or the second water tank 220 can pass through the water guide pipe 300 and the pressure chamber 410 and then be sprayed out from the spray port 500 .

[0046] Optionally, the first water tank 210 can store water for flushing teeth, and the second water tank 220 can store mouthwash. The volume of the first water tank 210 can be greater than the volume of the second water tank 220. After flushing teeth, the user can use the water flosser to spray out mouthwash for rinsing the mouth without carrying two separate sanitary products, which is highly portable. The present application only uses one water pipe 300 instead of two water pipes (water pipes) as in the background art, and the structure is relatively simple and the space allocation is more reasonable. The station switching process of the solenoid valve 100 does not wear the water pipe 300, making the water flosser strong and durable.

[0047] In one embodiment of the present application, see Figure 5 The solenoid valve 100 may include a valve body 140. The valve body 140 may include a main portion 141, a first inlet portion 120 and a second inlet portion 130 extending axially outward from the main portion 141, and an outlet portion 110 extending radially outward from the main portion 141. The interface between the first inlet portion 120 and the main portion 141 is a first end surface 121, and the interface between the second inlet portion 130 and the main portion 141 is a second end surface 131. The main portion 141 may be composed of two structures spliced ​​together.

[0048] An electromagnetic coil (not shown) is disposed in the main portion 141 or radially outside thereof. When energized, the electromagnetic coil can attract the valve core 150 to move toward the second end surface 131 along the axial direction of the main portion 141 and abut against the second end surface 131 .

[0049] See also Figure 5 and Figure 6A spring 180 is connected to the radial outer side of the valve core 150 , and the spring 180 also abuts against or is connected to the second end face 131 . After the electromagnetic coil is powered off, the spring 180 can drive the valve core 150 to move axially toward the first end face 121 and abut against the first end face 121 .

[0050] In one embodiment of the present application, see Figure 5 and Figure 6 The circumferential surface of the valve core 150 includes an arc surface 151 and a plane surface 152, the inner wall surface of the main part 141 in the circumferential direction includes a cylindrical surface 1411, and a liquid flow channel is formed between the plane surface 152 of the valve core 150 and the inner wall surface of the main part 141. When the valve core 150 blocks the first inlet 120, the liquid in the second inlet 130 can communicate with the outlet 110 through the liquid flow channel.

[0051] In one embodiment of the present application, see Figure 5 The valve core 150 includes a valve core main portion 153 and a valve core abutment portion 154. The valve core main portion 153 has the aforementioned arc surface 151 and plane 152. The end of the valve core 150 facing the first end surface 121 is formed with a cylindrical valve core abutment portion 154. In the axial projection of the valve core 150, the valve core abutment portion 154 is located inside the valve core main portion 153, so that when the valve core 150 blocks the first inlet portion 120, the space between the valve core abutment portion 154 and the outlet portion 110 is large, which facilitates the liquid from the second inlet portion 130 to communicate with the outlet portion 110.

[0052] In one embodiment of the present application, see Figure 7 and Figure 8 , a valve body support frame 160 is arranged outside the valve body 140, the valve body support frame 160 has a first valve body support frame flow channel 161 and a second valve body support frame flow channel 162, the second water tank 220 is connected to the first inlet portion 120 through the first valve body support frame flow channel 161, and the first water tank 210 is connected to the second inlet portion 130 through the second valve body support frame flow channel 162. Exemplarily, the first valve body support frame flow channel 161 directly extends into the second water tank 220, and the second valve body support frame flow channel 162 extends into the first water tank 210 through a bend. It can be understood that the valve body support frame 160 is convenient for fixing the position of the solenoid valve, and the first valve body support frame flow channel 161 and the second valve body support frame flow channel 162 are convenient for changing the axial direction of the first inlet portion 120 and the second inlet portion 130 of the solenoid valve 100 to the radial direction, which is convenient for connecting the valve with the water tank. The valve body support frame 160 can be composed of two structures spliced ​​together.

[0053] In one embodiment of the present application, the dual-tank water flosser may include a solenoid valve controller for controlling the on and off of the solenoid coil. The solenoid valve controller may include a switch button that can be manually adjusted so that the user can manually control the on and off of the solenoid coil 160. Of course, the solenoid valve controller may also be connected to an application of a mobile terminal to switch the liquid source at a fixed time, so that, for example, after the water flosser sprays water for 2 minutes, it automatically switches to mouthwash for rinsing.

[0054] In one embodiment of the present application, see Figure 3 The pump assembly 400 includes a pressure chamber 410, one end of which is connected to the water diversion pipe 300 and introduces the liquid in the solenoid valve 100 into the pressure chamber 410, a first one-way valve 411 is provided between the water diversion pipe 300 and the pressure chamber 410, the other end of the pressure chamber 410 is connected to the spray port 500 and allows the liquid in the pressure chamber 410 to spray out of the dental flosser through the spray port 500, and a second one-way valve 412 is provided between the pressure chamber 410 and the spray port 500. The second one-way valve 412 may be a duckbill valve.

[0055] In one embodiment of the present application, see Figure 2 The double water tank water flosser may include a battery 610 and a motor 620. The battery 610 is connected to the motor 620, and the output shaft of the motor 620 is connected to the pump assembly 400 to achieve the pumping of the liquid.

[0056] In one embodiment of the present application, see Figure 3 , the pump assembly 400 may include a gear shaft 420, an eccentric sleeve 430 and a transmission rod 440. The eccentric sleeve 430 is fixedly connected to the gear shaft 420, one end of the transmission rod 440 is sleeved on the eccentric sleeve 430, and the other end of the transmission rod is connected to the diaphragm 450, and the diaphragm 450 forms one side of the pressure chamber 410. Its working principle may be: the gear shaft 420 is driven by the motor 620 to drive the eccentric sleeve 430 to rotate, and the transmission rod 440 and the eccentric sleeve 430 form a cam mechanism to drive the transmission rod 440 to reciprocate. When the transmission rod 440 moves upward, the liquid in the pressure chamber 410 is pumped out of the ejection port 500. When the transmission rod 440 moves downward, the liquid in the first water tank 210 or the second water tank 220 is pumped into the pressure chamber 410.

[0057] Further, the pump assembly 400 may include a transmission gear 460, to which the output shaft of the motor 620 is connected, and the transmission gear 460 is meshed with the gear 421 of the gear shaft 420 to drive the gear shaft 420 to rotate. The transmission gear 460 and the gear 421 of the gear shaft 420 may be bevel gears, and their axes intersect.

[0058] In one embodiment of the present application, see Figure 1 and Figure 2 A first liquid replenishing port 211 is disposed on the side of the first water tank 210, and a second liquid replenishing port 221 is disposed on the side of the second water tank 220. The corresponding liquid can be replenished into each water tank through each liquid replenishing port.

[0059] In one embodiment of the present application, see Figure 2 , the first water tank 210 is located at the lower side of the second water tank 220.

[0060] The above is a preferred embodiment of the present application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present application.
