Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are for purposes of illustration and explanation only and are not intended to limit the present invention.
A water reservoir according to the invention is described below with reference to the accompanying drawings.
As shown in fig. 1 and 2, in the embodiment of the utility model, the utility model provides a water storage tank is provided, this water storage tank is including the box 10 that is used for the splendid attire washing liquid and install in the apron 60 of box 10 one side, the apron 60 is the cylinder structure, the bottom contact washing liquid of apron 60 and set up a plurality of exhaust holes 50 along axial extension, the top of apron 60 sets up towards the external world, and, there are a plurality of valve cavitys 40 that are used for installing case subassembly 20 at the lateral wall of apron 60 along circumference interval arrangement, a plurality of valve cavitys 40 and a plurality of exhaust holes 50 one-to-ones and communicate each other, case subassembly 20 can remove so that valve cavitys 40 and external intercommunication or block in valve cavitys 40.
Because the plurality of exhaust holes 50 on the bottom of the cover plate 60 are arranged at intervals along the circumferential direction, when the box body 10 rotates, the valve core assembly 20 at the topmost position moves towards the bottom of the valve cavity 40 due to the self gravity, so that the valve cavity 40 at the topmost position is communicated with the outside atmosphere, and at the moment, the exhaust holes 50 corresponding to the valve cavity are communicated with the atmosphere; the valve cavity 40 at other positions is blocked from the outside, and the corresponding exhaust hole 50 is closed accordingly.

Among them, the elastic member 22 is preferably a compression spring.
In the embodiment of the present invention, the plurality of valve cavities 40 are all located on the same cross-sectional circle, and each valve cavity 40 extends along the radial direction. The plurality of valve cavities 40 are positioned on a circle with the same cross section, so that when the box body 10 rotates, the gravity of the valve core 21 in the valve cavity 40 positioned at the highest position can be ensured to be right vertically downward, and the valve core 21 can be ensured to move to the bottom of the valve cavity 40 under the action of the gravity, so that the valve cavity 40 positioned at the topmost position is communicated with the outside; the valve chamber 40 in this configuration ensures that the reservoir is always open to atmosphere when the robot is operating in all directions.
In the embodiment of the present invention, a plurality of valve cavities 40 are uniformly spaced, wherein as shown in fig. 1, the number of valve cavities 40 is eight that are uniformly spaced, and in other embodiments, the number of valve cavities 40 can be changed according to actual requirements.
In the embodiment of the present invention, the exhaust screw 30 is installed on the inner side wall of the top of the valve cavity 40, the exhaust screw 30 has an air vent, and the diameter of the air vent is smaller than the diameter of the valve core 21. In order to prevent the valve core 21 in the valve cavity 40 from excessively moving towards the port of the valve cavity 40 and flushing out of the valve cavity 40 when the valve cavity 40 moves to the top, the exhaust screw 30 is installed on the inner side wall of the top of the valve cavity 40, the exhaust screw 30 plays a role in blocking the valve core 21, when the top of the valve core 21 abuts against the exhaust screw 30, the valve cavity 40 is blocked from the outside, and when the top of the valve core 21 is separated from the exhaust screw 30 and moves towards the bottom of the valve cavity 40, the outside air enters the valve cavity 40, so that the exhaust hole 50 is communicated with the outside.
In the embodiment of the present invention, the exhaust holes 50 are located between the bottom of the corresponding valve cavity 40 and the exhaust screws 30, the exhaust holes 50 penetrate through the wall body of the cover plate 60 and are communicated with the valve cavity 40, when the valve cavity 40 is communicated with the outside, the outside air enters the valve cavity 40, and the air in the valve cavity 40 enters the exhaust holes 50, so that the exhaust holes 50 are opened; when the valve cavity 40 is blocked from the outside, the valve cavity 40 is in a closed state, and the exhaust hole 50 cannot be communicated with the outside, that is, the exhaust hole 50 is closed.
In the embodiment of the present invention, in order to further strengthen the connection sealing ring 70 between the exhaust screw 30 and the valve cavity 40, the sealing ring 70 is disposed at the connection position between the exhaust screw 30 and the valve cavity 40.
In the embodiment of the present invention, the valve core 21 is a ball valve core 21, and the central axis of the ball valve core 21 coincides with the central line between the exhaust screws 30, so that the valve core 21 can be directly clamped in the inner cavity of the exhaust screws 30 when moving towards the top end of the valve cavity 40, thereby improving the sealing performance of the valve cavity 40.
In the embodiment of the present invention, the parameters of the elastic member 22 and the valve core 21 need to satisfy the following requirements:
F 1 +F 2 >Gcosθ+F 3
wherein, F 1 The pressure of the cleaning liquid on the valve core 21; f 2 The elastic force of the elastic member 22 to the valve core 21; f 3 The pressing force of the negative pressure atmosphere in the tank 10 on the valve element 21, θ is the offset angle between the central axis of the valve element 21 and the gravity direction, and G is the weight of the valve element 21.
Specifically, the derivation process of the above parameters satisfying the formula is as follows:
F 1 pressure of the cleaning liquid on the valve member 21 (if the valve member 21 is not immersed in the cleaning liquid, F) 1 Zero); f 2 Is the elastic force of the spring to the valve core 21; f 3 The negative pressure of the atmosphere in the tank 10 is applied to the valve core 21 (if the reservoir is connected to the atmosphere, F) 3 Zero); valve core21, a force-bearing area and an offset angle theta from the gravity direction, are as follows:
F 1 ＝ρghA (1)
in the formula (1), ρ is the density of the cleaning liquid, and h is the height of the valve core 21 from the water surface
F 2 ＝Kd x (2)
In the formula (2), K is the spring elastic coefficient, d x Is the compression amount of the spring
F 3 ＝(P-P 0 )A (3)
In the formula (3), P is standard atmospheric pressure, P 0 Is the atmospheric pressure in the water storage tank
Therefore, in order to avoid the cleaning liquid flowing out from other valve cavities 40 when the valve cavity 40 at the top is communicated with the outside, it is necessary to satisfy:
F 1 +F 2 >Gcosθ+F 3 i.e., (ρ gh-P + P) 0 )A+kd x >Gcosθ
At this time, the valve chamber 40 located at the topmost portion is in communication with the outside, F 3 Is zero, theta is zero, and the topmost valve chamber 40 is not immersed in cleaning fluid, F 1 Zero, while in order to ensure that at least the topmost valve chamber 40 is in communication with the outside, it is necessary to satisfy:
G>F 2 i.e. G>kd x
Therefore, as long as the parameters of the elastic element 22 and the valve core 21 meet the requirements, the opening or closing of each exhaust hole 50 can be automatically adjusted under the action of the self gravity of the valve core 21 and the elastic force of the elastic element 22, and the water storage tank can be communicated with the atmosphere in each operation direction of the robot.
