DETAILED DESCRIPTION

Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, but cannot be construed as limitation to the present invention.
A filtering cartridge assembly according to embodiments of the present invention will be described below with reference to the accompanying drawings.
As shown in Figs. 1 to 4, the filtering cartridge assembly according to the embodiments of the present invention includes a water collecting tray 1, a water recovery tray 2, a support frame 3, a water supplying pipe 5 and a plurality of water guiding members 4.
The water collecting tray 1 includes a side wall and a bottom wall, the side wall and the bottom wall of the water collecting tray 1 define a water collecting groove 11, and the water collecting tray 1 includes a first water supplying hole 111 and a plurality of water draining holes 1121 in its bottom wall. It can be understood that the first water supplying hole 111 is communicating with (fluidically connected to) the water collecting groove 11, so that the water can enter the water collecting groove 11 through the first water supplying hole 111.
The water recovery tray 2 is located below the water collecting tray 1, and includes a side wall and a bottom wall, and the side wall and the bottom wall of the water recovery tray 2 define a water recovery groove 21.
The plurality of water guiding members 4 are in one-to-one correspondence with the plurality of water draining holes 1121, an upper end of the water guiding member 4 passes through the corresponding water draining hole 1121, a lower end of the water guiding member 4 is connected to the bottom wall of the water recovery tray 2, and there is a drainage gap between a peripheral wall of the water guiding member 4 and a wall defining the corresponding water draining hole 1121.
In other words, the drainage gap is formed between the wall defining the water draining hole 1121 and the peripheral wall of the corresponding water guiding member 4.
It can be understood that the water in the water collecting groove 11 will flow out from the drainage gap under the influence of gravity, and the outflowing water will adhere to the water guiding member 4 and flow downwards by the guide of the water guiding member 4 until it flows into the water recovery groove 21. During this process, the water flowing on the water guiding member 4 will form a water film, which increases the contact area between the water and the air, so that it is easy for the water on the water guiding member 4 to be volatilized to form the water vapor.
It should be noted that the gap in a radial direction between the peripheral wall of the water guiding member 4 and the wall defining the water draining hole 1121 is small, that is, the radial dimension of the drainage gap is small, thereby ensuring that the water flowing out of the drainage gap can adhere to the water guiding member 4 and will not drop directly into the water recovery groove 21 through the drainage gap.
The water recovery tray 2 has a second water supplying hole 211 and a plurality of water recovery holes 212 in its bottom wall. It can be understood that a part of the water flowing out from the water draining hole 1121 is volatilized into the air, and another part of the water flows into the water recovery groove 21 through the water guiding member 4. The water recovery groove 21 is used to collect the part of the water flowing down from the water guiding member 4, and the water in the water recovery groove 21 can be discharged through the plurality of water recovery holes 212 to recover the water.
The support frame 3 is connected between the water collecting tray 1 and the water recovery tray 2. It can be understood that the support frame 3 is used to support the water collecting tray 1 and the water recovery tray 2, thereby allowing the structure of the filtering cartridge assembly according to the embodiments of the present invention to be more stable.
The water supplying pipe 5 is located between the water collecting tray 1 and the water recovery tray 2, an upper orifice of the water supplying pipe 5 is communicating with the first water supplying hole 111, a lower orifice of the water supplying pipe 5 is communicating with the second water supplying hole 211, and the water supplying pipe 5 is adapted to be connected with a water pump to supply water into the water collecting groove 11.
The water in the water collecting groove 11 of the filtering cartridge assembly according to the embodiments of the present invention infiltrates downwards to the water guiding member 4 through the drainage gap, and the water film can be formed on the peripheral wall of the water guiding member 4 during the downward flow of the water, thus increasing the contact area between the water and the air, and making it easy for the water on the water guiding member 4 to be volatilized to form the water vapor.
Compared with the related art, the water guiding member 4 of the filtering cartridge assembly according to the embodiments of the present invention allows the water to be volatilized easily, and also will not accumulate water scale and bacteria. Therefore, the filtering cartridge assembly according to the embodiments of the present invention does not need to be cleaned regularly, does not become yellow and smelly, and even will not have a clogging problem, thus facilitating use and providing a good user experience.
Therefore, the filtering cartridge assembly according to the embodiments of the present invention does not need to be cleaned regularly, is convenient to use, and can also improve the user experience.
In some embodiments, as shown in Fig. 2, a rib 41 is on the peripheral wall of the water guiding member 4, and the rib 41 extends along a length direction of the water guiding member 4 (i.e. an up-down direction in Fig. 1) and runs through the drainage gap. The length direction of the water guiding member 4 is consistent with the up-down direction.
It can be understood that when the amount of the water in the water collecting groove 11 is small, it is easy for the water to form water droplets under the action of its tension. After the rib 41 on the water guiding member 4 comes into contact with the water droplet, the surface tension of the water droplet will be destroyed, so that it is easy for the small amount of water in the water collecting groove 11 to infiltrate downwards to the water guiding member 4 through the drainage gap, thus reducing the influence of the amount of the water in the water collecting groove 11 on the normal operation of the filtering cartridge assembly.
In addition, after the rib 41 on the water guiding member 4 comes into contact with the water droplet, the surface tension of the water droplet will be destroyed, so that a uniform water film is formed easily when the water flows downwards, which is conducive to the volatilization of the water on the water guiding member 4.
In some embodiments, as shown in Fig. 2, a plurality of ribs 41 are provided, the plurality of ribs 41 are arranged along a circumferential direction of the water guiding member 4, and each of the plurality of ribs 41 extends in the same direction which is consistent with the length direction of the water guiding member 4.
In some embodiments, as shown in Fig. 2, the wall defining the water draining hole 1121 has a water leakage slot 11211, and the drainage gap is formed between a wall defining the water leakage slot 11211 and the peripheral wall of the water guiding member 4. That is, the wall defining the water draining hole 1121 is partially depressed to form the water leakage slot 11211, so that the wall defining the water leakage slot 11211 is a part of the wall defining the water draining hole 1121, but is depressed relative to another part of the wall defining the water draining hole 1121.
It can be understood that the wall defining the water draining hole 1121 has the water leakage slot 11211, so that the water flowing out from the water leakage slot 11211 can flow down the water guiding member 4 in strands, which is conducive to forming the uniform water film on the water guiding member 4. Therefore, the contact area between the water on the water guiding member 4 and the air is increased, thus facilitating the volatilization of the water on the water guiding member 4.
In some embodiments, as shown in Fig. 2, the water guiding member 4 is a rod, the wall defining the water draining hole 1121 includes a contact part 11212, and a plurality of contact parts 11212 are provided and spaced apart from each other. The contact parts 11212 are alternated with the water leakage slots 11211 along a circumferential direction of the water draining hole 1121. The contact parts 11212 are in contact with the peripheral wall of the water guiding member 4.
It can be understood that the plurality of contact parts 11212 of the water draining hole 1121 are in contact with the peripheral wall of the water guiding member 4, that is, the plurality of contact parts 11212 clamp the water guiding member 4 tightly, thus ensuring the mounting stability of the water guiding member 4.
In other embodiments, the water guiding member 4 is a rope, the upper end of the water guiding member 4 is connected to the water collecting tray 1, and the lower end of the water guiding member 4 is connected to the water recovery tray 2, so that the water guiding member 4 is kept in a tightened state.
It can be understood that an outer surface of the rope is relatively rough, and the friction force between the outer surface of the rope and the water is relatively large, so that the falling time of the water can be increased, and the water on the water guiding member 4 can be fully volatilized.
In some embodiments, as shown in Fig. 2, a plurality of ribs 41 are provided, the plurality of ribs 41 are spaced apart from each other along the circumferential direction of the water guiding member 4, a plurality of water leakage slots 11211 are provided, and the plurality of water leakage slots 11211 are spaced apart from each other along the circumferential direction of the water draining hole 1121, and the plurality of ribs 41 are in one-to-one correspondence with the plurality of water leakage slots 11211.
It can be understood that when the amount of the water in the water collecting groove 11 is small, the water in the water collecting groove 11 may be unevenly distributed, while the plurality of ribs 41 are arranged along the circumferential direction of the water guiding member 4, so that the water droplets at different positions can be in contact with the ribs 41, and thus it is easy for the small amount of water in the water collecting groove 11 to infiltrate downwards to the water guiding member 4 through the drainage gap, reducing the influence of the amount of the water in the water collecting groove 11 on the normal operation of the filtering cartridge assembly.
In addition, the plurality of ribs 41 increase the area of the peripheral wall of the water guiding member 4. When the water adheres to the peripheral wall of the water guiding member 4, the surface area of the formed water film will also increase, so that the contact area between the water on the water guiding member 4 and the air increases, which is conducive to the volatilization of the water on the water guiding member 4.
In some embodiments, as shown in Fig. 2, the bottom wall of the water collecting tray 1 has a plurality of water guiding recesses 112, the plurality of water guiding recesses 112 are in one-to-one correspondence with the plurality of water draining holes 1121, and the water draining hole 1121 is formed in a bottom wall of the corresponding water guiding recess 112. That is, the bottom wall of the water collecting tray 1 is partially depressed to form the water guiding recess 112, so that the bottom wall of the water guiding recess 112 is a part of the bottom wall of the water collecting tray 1, but is depressed relative to another part of the bottom wall of the water collecting tray 1.
It can be understood that an upper surface of the bottom wall of the water collecting tray 1 is higher than an upper surface of the bottom wall of the water guiding recess 112, so that it is easy for the water in the water collecting groove 11 to flow into the water guiding recess 112 under the influence of gravity. When the amount of the water in the water collecting groove 11 is small, the water in the water collecting groove 11 can be collected in multiple water guiding recesses 112, so as to ensure that there is a sufficient amount of water in the water guiding recesses 112 to flow to the water guiding member 4 when the amount of the water in the water collecting groove 11 is small, thus reducing the influence of the amount of water on the normal operation of the filtering cartridge assembly according to the embodiments of the present invention.
In some embodiments, as shown in Figs. 1 and 4, the water collecting tray 1 has a first water falling hole 12, and the water collecting groove 11 surrounds the first water falling hole 12. In other words, an inner edge of the water collecting groove 11 is connected to the first water falling hole 12. The side wall of the water collecting tray 1 includes a first side wall 131 and a second side wall 132, the first side wall 131 surrounds the second side wall 132, and the second side wall 132 has an overflow port 133 connecting the water collecting groove 11 with the first water falling hole 12. In other words, the first side wall 131, the second side wall 132 and the bottom wall of the water collecting tray 1 define the water collecting groove 11.
Specifically, the second side wall 132 of the water collecting tray 1 is configured as an annular wall, the annular wall has an inner wall surface and an outer wall surface, the outer wall surface of the annular wall faces towards the first side wall 131 (i.e., an inner wall surface of the first side wall 131), and the inner wall surface of the annular wall defines the first water falling hole 12. The annular wall has a notch, and the notch connects the inner wall surface of the annular wall with the outer wall surface of the annular wall to define the overflow port 133. That is, the overflow port 133 runs through the inner wall surface and the outer wall surface of the annular wall.
The water recovery tray 2 has a second water falling hole 22, the water recovery groove 21 surrounds the second water falling hole 22, and the first water falling hole 12 is corresponding to the second water falling hole 22 in the up-down direction.
It can be understood that when the amount of the water in the water collecting tray 1 is too large, the water in the water collecting tray 1 can flow out from the overflow port 133, and the overflowing water enters the first water falling hole 12 and is discharged through the second water falling hole 22, so as to recover the overflowing water.
In some embodiments, as shown in Fig. 4, the filtering cartridge assembly according to the embodiments of the present invention further includes a water falling pipe 6, an upper orifice 611 of the water falling pipe 6 is communicating with the first water falling hole 12, and a lower orifice 621 of the water falling pipe 6 is communicating with the second water falling hole 22. It can be understood that the first water falling hole 12 and the second water falling hole 22 are communicating with each other through the water falling pipe 6, so that the overflowing water enters the water falling pipe 6 through the first water falling hole 12 and then is discharged through the second water falling hole 22, so as to recover the overflowing water.
Further, at least part of an inner peripheral surface of the water falling pipe 6 is a tapered surface, and a perimeter of an inner peripheral contour of a cross section of the water falling pipe 6 gradually decreases from top to bottom. The cross section of the water falling pipe 6 is perpendicular to the up-down direction.
In some embodiments, as shown in Fig. 4, the water falling pipe 6 includes a first section 61 and a second section 62, and a lower end of the first section 61 is connected to an upper end of the second section 62. An inner peripheral surface of the first section 61 is a cylindrical surface, that is, a perimeter of an inner peripheral contour of a cross section of the first section 61 is consistent from top to bottom, and an inner peripheral surface of the second section 62 is a tapered surface.
In some other embodiments, the inner peripheral surface of the water falling pipe 6 is a tapered surface, that is, the perimeter of the inner peripheral contour of the cross section of the water falling pipe 6 gradually decreases from top to bottom.
It can be understood that the at least part of the inner peripheral surface of the water falling pipe 6 is the tapered surface, so that the water flowing into the water falling pipe 6 flows out of the second water falling hole 22 along the inner peripheral surface of the water falling pipe 6 slowly, instead of dropping vertically with a noise, thus improving the user experience.
In some embodiments, the inner peripheral surface of the water falling pipe 6 may be a pyramid surface or a conical surface.
As shown in Fig. 4, the inner peripheral surface of the water falling pipe 6 is a conical surface. It can be understood that the inner peripheral surface of the water falling pipe 6 is a curved surface, and the friction force between the water in the water falling pipe 6 and the inner peripheral surface of the water falling pipe 6 is small, thus ensuring that the water in the water falling pipe 6 can be discharged smoothly.

One group of water guiding members 4 includes multiple water guiding members 4, the multiple water guiding members 4 are spaced apart from each other along the circumferential direction of the water collecting tray 1, and the multiple water guiding members 4 are in one-to-one correspondence with the multiple water draining holes 1121.
