Detailed Description

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1, a filtering device with a valve according to an embodiment of the present invention is provided, including a mixing water outlet pipe 10 and at least two drainage channels 20, where each drainage channel 20 is communicated with the mixing water outlet pipe 10; wherein, a filtering filter element 30 is arranged in at least one of the drainage channels 20; at least one of the drainage channels 20 is provided with a valve 50.

As described above, the drain passage 20 is a passage through which water can be drained. Each of the drainage channels 20 is communicated with the mixing outlet pipe 10, so that the drainage channels 20 are connected in parallel, that is, the outlet water of each drainage channel 20 is finally merged in the mixing outlet pipe 10 and then discharged from the mixing outlet pipe 10.

As mentioned above, the filtering core 30 is disposed in at least one of the drainage channels 20, which means that at least one of the drainage channels 20 has the function of filtering clean water. For example, there are two drainage channels 20, one drainage channel 20 may be provided with a filter element 30, and the other drainage channel may be provided with the filter element 30 or without the filter element 30.

As mentioned above, at least one of the drainage channels 20 is provided with a valve 50, which indicates that at least one of the drainage channels 20 can control whether water is passed through the valve 50. The valve 50 may be disposed on the drain passage 20 having the filtering core 30, or may be disposed on the drain passage 20 not having the filtering core 30, and the valves 50 may be disposed on all the drain passages 20, and may be adjusted according to specific use requirements. For example, in order to control the use of the filtering core 30, a valve 50 may be disposed on the drainage channel 20 provided with the filtering core 30, when the drainage channel 20 provided with the filtering core 30 needs to work, the corresponding valve 50 is opened, otherwise, the valve 50 is closed, so that the service life of the filtering core 30 can be prolonged; for another example, when it is required to prevent the problem that the whole filtering device cannot be used after the drainage channel 20 provided with the filtering filter element 30 is blocked and the filtering effect is not high at the beginning of water circulation, a valve 50 may be arranged on the drainage channel 20 not provided with the filtering filter element 30, and when the filtering filter element 30 is blocked and water cannot be discharged or the water discharge amount is low, the corresponding valve 50 is opened to increase the water discharge amount of the filtering device with the valve, so as to ensure that a pet has enough water to drink and prevent the water pump from being burnt; for another example, there are three drainage channels 20, wherein three drainage channels 20 are provided with the filtering core 30, one of the drainage channels 20 is not provided with the valve 50, and the other two drainage channels are provided with the valves 50, when the drainage channel 20 not provided with the valve 50 is blocked to cause water to be unable to flow out or the water output is low, the valve 50 of one of the other two drainage channels 20 can be opened, and when the drainage channel 20 opened with the valve 50 is blocked to cause water to be unable to flow out or the water output is low, the valve 50 of the last drainage channel 20 is opened, so that the water output can be maintained, and the purity of the water output can also be maintained.

As described above, the filter element 30 includes a plurality of filter cotton 31, activated carbon, ultrafiltration membrane filaments, and the like. Further, the filter cartridges 30 in the drain passages 20 each provided with the filter cartridges 30 may be different types of filter cartridges 30, and the different types of filter cartridges 30 may perform different filtering functions and have different blocking probabilities.

In this embodiment, when the filtering device with the valve is applied to a pet drinking fountain, the water inlets of the drainage channels 20 are communicated with the water tank of the pet drinking fountain, and the water pump may be disposed corresponding to the mixing water outlet pipe 10 to pump water through the mixing water outlet pipe 10, or may be disposed in the water tank to supply water to the water inlets of the drainage channels 20.

In this embodiment, after being discharged through the mixing outlet pipe 10 of the filtering device with the valve, the water in the water tank of the pet water dispenser finally flows back to the water tank through the drinking water tray and other devices, thereby providing circulating water for the pet. The drain passage 20 with the filter cartridge 30 in the above-mentioned valved filter device can play a role of filtering clean water without the valve 50 or with the valve 50 opened because of the circulating water, so that the water flowing back to the water tank may be polluted, but if the use time is too long or the water is polluted seriously, some filter cartridges 30 may be blocked, and at this time, the water can be continuously discharged from the drain passage 20 which is not blocked (if the valve 50 is arranged, the valve 50 needs to be opened), thereby keeping the water circulation and preventing the water pump from being burnt out.

In one embodiment, at least one of the drainage channels 20 is an ultrafiltration channel 23, and the ultrafiltration channel 23 is a channel in which the filtration cartridge 30 is disposed; the filtering core 30 in the ultrafiltration channel 23 is a filter core made of an ultrafiltration membrane or ultrafiltration membrane filaments.

As described above, the ultrafiltration channel 23 is the ultrafiltration filter element 32 made of the ultrafiltration membrane or ultrafiltration membrane yarn as the filter element 30, and can better purify impurities in water, not only filter fine particles, but also filter various bacteria, and improve the purity of the drinking water for pets. Since the valved filter device is typically used in a recirculating water system, substantially all of the water flows through the ultrafiltration channel 23 and is purified when the number of cycles is high.

Further, the ultrafiltration channel 23 may be provided with the valve 50, or may not be provided with the valve 50. Specifically, when the valve 50 is arranged, the valve can be opened or closed according to needs, for example, when the valve is applied to a pet water dispenser, purified water is added into a water tank of the pet water dispenser, so that the ultrafiltration channel 23 is not needed to be used for purifying water in the early water circulation process, the valve 50 of the ultrafiltration channel 23 is closed at this time, and the valve 50 of the ultrafiltration channel 23 is opened after the water is circulated for a period of time, so that the service time of the filter element 30 in the ultrafiltration channel 23 can be prolonged. Or opening the valve 50 of the ultrafiltration channel 23 when the pollution degree of the circulating water is detected to reach the preset index.

In one embodiment, the ultrafiltration channel 23 is the drain channel 20 without the valve 50. The ultrafiltration channel 23 filters the circulating water passing through until it is not completely blocked.

Referring to fig. 3, in one embodiment, the drainage channels 20, other than the ultrafiltration channel 23, are distributed inside and/or outside the ultrafiltration channel 23.

As described above, the other drainage channels 20 may be the drainage channel 20 and the drainage channel 20, etc. in the figure, that is, the other drainage channels 20 which are not the ultrafiltration channel 23. These channels may be arranged outside the ultrafiltration channel 23, inside the ultrafiltration channel 23, partly inside the ultrafiltration channel 23 and partly outside the ultrafiltration channel 23. Can be combined at will according to the design requirements of products.

Referring to fig. 2, in one embodiment, the pipes of each of the drainage channels 20 are integrally formed together.

As described above, all the drainage channels 20 are integrally formed, so that the structure of the filtering device with the valve is relatively compact, the installation process of the filtering device with the valve on the pet water dispenser is reduced, and the production process of each drainage channel 20 can be reduced.

Furthermore, an adhesive layer for fixing the ultrafiltration membrane or the ultrafiltration membrane filaments is arranged in the ultrafiltration channel 23; the drainage channels 20 are arranged on the adhesive layer.

As mentioned above, the glue layer is a structure for encapsulating the ultrafiltration membrane or the ultrafiltration membrane filaments, for example, one end of each of the plurality of ultrafiltration membrane filaments is encapsulated in the glue layer and penetrates through the glue layer, so that water can flow through the glue layer through the ultrafiltration membrane filaments, and the glue layer is fixedly mounted on the inner wall of the ultrafiltration channel 23. In this embodiment, the drainage channel 20 is arranged on the adhesive layer, which is simple and convenient. Further, the drainage channels 20 disposed on the glue layer are generally through holes in the glue layer that avoid the filaments of the ultrafiltration membrane, and the filter cartridges 30 are not typically disposed in the through holes. Further, if the filter element 30 is disposed in the through hole, the filter element 30 may be a gauze or a filter cotton 31, etc.

In one embodiment, the valve 50 can be disposed at any position corresponding to the channel, as shown in fig. 1 and 2, the drainage channel 20 with the filtering cartridge 30 is provided with the valve 50 disposed at the side of the filtering cartridge 30 away from the mixing outlet pipe 10; as shown in fig. 3, the drainage channel 20 with the filter cartridge 30 is provided with a valve 50 disposed on the pipeline between the filter cartridge 30 and the mixing outlet pipe 10.

In one embodiment, at least one of the drainage channels 20 is a straight drainage channel 21 where the filter cartridge 30 is not disposed; the valve 50 is arranged on the straight drainage channel 21.

As mentioned above, at least one straight drainage channel 21 is provided in the filtering device with valve, when the drainage channel 20 with the filtering core 30 is blocked and the pet can not be normally supplied with water, the valve 50 of the straight drainage channel 21 can be opened to ensure that the pet can be provided with enough drinking water, and when the valve 50 of the straight drainage channel 21 is not opened, the water discharged by the filtering device with valve is filtered water, and the purity is relatively high.

In one embodiment, the valved filter device is provided with three drainage channels 20, a straight drainage channel 21, a general filtering drainage channel 22 provided with a filter cotton 31, and an ultrafiltration channel 23 provided with an ultrafiltration filter element 32. In normal operation, the valve 50 on the ordinary filtering drainage channel 22 and the ultrafiltration channel 23 is opened, the valve on the direct drainage channel 21 is closed, and when the ordinary filtering drainage channel 22 and the ultrafiltration channel 23 are blocked, the direct drainage channel 21 can be opened.

In one embodiment, the valve 50 includes one or more of a manually-operated valve 52 that is manually opened and closed, an electrically-controlled valve 53 that is electrically controlled, and a physically automated valve 51 that is based on the action of water pressure or gravity.

As described above, the manual valve 52 is a valve 50 that needs to be opened or closed by a user through manual control, and generally includes a force application portion and a valve core, and the valve core is controlled to be opened or closed by a user through a knob of the force application portion. The electrically controlled valve 53 is the valve 50 controlled by a sensor, for example, a temperature sensor is provided in the drainage channel 20, when the temperature is higher than a certain value, the electrically controlled valve 53 is opened or closed, etc., or a pressure sensor is provided in the drainage channel 20, when the water pressure in the drainage channel 20 is higher than a certain value, the electrically controlled valve 53 is opened or closed. The physical automatic valve 51 is a valve 50 that can be automatically opened or closed without manual operation by a user and electronic sensing, such as a water pressure-based valve 50, which may be a rubber plug, and one end of the physical automatic valve is fixed to a side wall of the drainage channel 20, and under a normal state, the physical automatic valve is plugged in the drainage channel 20 under the action of its own elasticity, and when the pressure provided by the water pressure in the drainage channel 20 is greater than the elasticity generated by the physical automatic valve, water in the physical automatic valve will turn over the rubber plug along the connection with the drainage channel 20 to open the plugged portion, so that the water flows through the drainage channel 20; for example, the gravity-based valve 50 may include a section of a thin drain hole in the drain channel 20, a gravity plug above the drain hole, and the gravity plug may be configured to block the top end of the drain hole when the impact force provided by the water in the drain channel 20 is smaller than the gravity of the gravity plug, and may be configured to be lifted to conduct the drain channel 20 when the impact force provided by the water in the drain channel 20 is larger than the gravity of the gravity plug. In one embodiment, the valve 50 used at the time is the physical automatic valve 51, and the filter element 30 of some of the drainage channels 20 is completely or partially blocked, at this time, the water pressure applied to the physical automatic valve 51 by the water pressure provided by the water pump becomes large, and when the water pressure is greater than a certain critical value, the physical automatic valve 51 is opened, so that the filtering device with the valve can normally lead out water to be provided for pets to drink.

Referring to fig. 4, in an embodiment, when the valve 50 is the physical automatic valve 51, a transparent window (not shown) is disposed on a side wall of the drain passage corresponding to the physical automatic valve 51, and the transparent window is used for a user to determine a position of the valve plug 512 of the physical automatic valve.

As described above, the transparent window is a window that can be transparent, and the contents of the drainage channel 20 can be observed through the transparent window. In this embodiment, because a plurality of two drainage channels are provided, water will substantially always flow out from the mixing water outlet pipe 10, but it is not clear which drainage channels 20 the water in the mixing water outlet pipe 10 comes from, and after the transparent window is provided on the side wall of the drainage channel 20, the condition of the valve can be checked through the transparent window, so as to determine whether the drainage channel 20 corresponding to the valve is conducted, and further determine whether the filtering core needs to be replaced. For example, when the physical automatic valve 51 is disposed on the in-line water channel 21, in the normal filtering process, the physical automatic valve 51 of the in-line water channel 21 is closed, and water is discharged from the other water channels 20 in which the filter element is disposed, so as to improve the filtering effect, but when the user observes that the physical automatic valve 51 of the in-line water channel 21 is turned on through the transparent window, it indicates that a certain filter element 30 is blocked, and thus the water pressure in the in-line water channel 21 becomes large, so as to turn on the physical automatic valve 51, the user can determine that there is a filter element 30 to be replaced. For another example, when the physical automatic valve 51 is disposed on the drainage channel having the filtering core 30, when the filtering core 30 is blocked, the corresponding physical automatic valve 51 is closed, and at this time, after the user observes that the corresponding physical automatic valve 51 is closed through the transparent window, it can be determined that the filtering core in the drainage channel 20 corresponding to the physical automatic valve 51 is blocked and needs to be replaced.

In one embodiment, when the drain passage 20 for the physical automatic valve 51 is the drain passage 20 for the filter cartridge 30, the physical automatic valve 51 is disposed on the pipeline between the filter cartridge and the mixing outlet pipe.

As described above, the physical automatic valve 51 includes the circular truncated cone-shaped valve tube 511 and the valve plug 512, the large opening end of the valve tube 511 faces upward, the small opening end is below the large opening end, the valve plug 512 blocks the small opening end under the action of gravity, so that the physical automatic valve 51 is closed, when the water pressure in the drainage channel 20 overcomes the gravity of the valve plug 512, the valve plug 512 is pushed away from the small opening end, and the physical automatic valve 51 is turned on, wherein the valve plug 512 is generally spherical. Thus, in the case of normal use, when the filter element 30 is not blocked, the water pressure provided by the water of the filter element 30 is large, and the valve plug 512 can be pushed open, and when the filter element 30 is completely or partially blocked, the water pressure provided by the water of the filter element 30 is small, and the valve plug 512 cannot be pushed open, so that a user can determine whether the filter element 30 is blocked according to the transparent window, and determine whether the filter element 30 needs to be replaced. Furthermore, marks such as scales are arranged on the transparent window corresponding to the physical automatic valve 51, and whether the filter element 30 needs to be replaced or not can be determined according to the relationship between the valve plug 512 and the scales.

Further, the valved filtering apparatus further includes a water inlet pipe 40; each of the drainage passages 20 communicates with the inlet pipe 40.

As described above, each of the drainage passages 20 communicates with the inlet pipe 40, so that water can be supplied to each of the drainage passages 20 through one inlet pipe 40. Specifically, the water inlet pipe 40 is communicated with a water tank of the pet water dispenser, a water pump is arranged in the water tank, and water is supplied to the water supply pipe through the water pump, so that the water supplied by one water pump respectively enters each drainage channel 20 after passing through the water inlet pipe 40, and is finally discharged after passing through the mixed water outlet pipe 10. It should be noted that the water pump generally pumps water from the bottom of the water tank and then supplies water to each of the drainage channels 20 through the water inlet pipe 40.

Referring to fig. 5, the embodiment of the present application further provides a pet water dispenser, including a filtering device 400 with a valve according to any of the above embodiments.

In one embodiment, the pet water dispenser includes a water tank 100, a water pump 200, a drinking tray 300, and the above-described valved filter device 400. The drinking water tray 300 is provided above the water tank 100, the water pump 200 is provided in the water tank 100, and the valved filter 400 is provided at an outer or inner sidewall of the water tank 100 and then communicates with the water pump 200. When the pet water dispenser works, the water pump 200 conveys water in the water tank 100 to the filtering device 400 with the valve, the water is discharged from the mixing water outlet pipe 10 of the filtering device 400 with the valve and flows into the water drinking tray 300, and the water in the water drinking tray 300 flows back to the water tank 100 through the preset water leakage structure 301.

In another embodiment, the pet drinking machine includes a water tank 100, a water pump 200 and the above-mentioned filter device 400 with a valve, the water pump 200 is disposed in the water tank 100, and the filter device 400 with a valve is disposed on the outer sidewall or the inner sidewall of the water tank 100 and then communicated with the water pump 200.
