The upper end of the filtering assembly is communicated with the water outlet, the lower end of the filtering assembly is communicated with the inner cavity of the water tank. A water diversion guide groove is arranged at the lower end of the filtering assembly, and the water diversion guide groove is communicated with the filtering assembly. The inner side wall of the water diversion guide groove is inclined inward from top to bottom to form a water diversion guide surface, and the water diversion guide surface is used for diverting the water passing through the filtering assembly into the inner cavity of the water tank. The filtering assembly includes a filtering box and a filtering disc and a filter element installed inside the filtering box. The filter element of this patent can only filter water. After a long time, the filter element cannot be automatically cleaned, and the filtering effect will become worse.

[0004] Therefore, it is necessary to propose a pet drinking fountain with a filter having an anti-flushing function. Summary of the Invention

[0005] The purpose of the utility model is to overcome the above-mentioned deficiencies of the prior art, and provide an anti-flushing filter and a pet drinking fountain, aiming to solve the technical problem that the filter element in the prior art cannot be automatically cleaned and the filtering effect will become worse.

[0009] Preferably, a second blocking member is disposed within the second filtration channel, the second filtration channel includes a second blocking seat, an opening is formed at the top of the second blocking seat; a plurality of axially distributed inner grooves are formed in the side of the second blocking seat; a second spring is disposed between the top of the second blocking seat and the second blocking member.

[0010] Preferably, a second sealing ring is disposed at the inner bottom of the second filtration channel; the second blocking seat and the second sealing ring cooperate to form a seal.

[0011] The present utility model further provides a pet drinking fountain, which comprises the backwashing filter according to any one of the claims, and further comprises a base, and a filter mounting seat is disposed on the base; the filter is detachably disposed on the filter mounting seat.

[0012] Preferably, the filter mounting seat is provided with two first pipes extending upward, and the two first pipes can be respectively inserted into the first filtration channel and the second filtration channel.

[0013] Compared with the prior art, the beneficial effects of the backwashing filter and the pet drinking fountain provided by the present utility model are as follows:

[0014] 1. The filter is divided into two halves, which are respectively connected to clean water and sewage. When the water flow direction is different, the filtration or cleaning state can be switched.

[0015] 2. The filter is detachably disposed on the base. When it is pulled out, the blocking member will block the first filtration channel and the second filtration channel, so that the water in the filter will not flow out, which is safer and more hygienic.

[0016] 3. The ultrafiltration filter element blocks particulate matter at one end of the sewage through extremely small pores. When the purified water flows back in the reverse direction, the blocked particulate matter can be flushed into the sewage tank, thus preventing the filter element from being clogged. In this way, the purpose of cleaning the filter element is achieved, while some adsorption-type filter elements cannot be cleaned in this manner.

A filter mounting seat 21 is provided on the base 2, and a backwash filter is detachably installed on the filter mounting seat 21. The filter can filter the water in the sewage tank of the pet water dispenser and enter it into the water purification tank. However, during long-term use, the filtering effect of the filter will deteriorate, and it is complex, time-consuming and laborious to disassemble and clean it frequently. Through backwashing, the water in the water purification tank after flushing the filter enters the sewage tank, and the pumping process is realized by a water pump.

[0031] The filter mounting seat 21 is provided with two first pipes 211 extending upward, and the two first pipes 211 can be respectively inserted into the first filtering channel 12 and the second filtering channel 13.

[0032] In an optional embodiment, the backwashing filter includes a filter housing 1, a partition 11 disposed in the filter housing 1, and a first filtering channel 12 and a second filtering channel 13 disposed on both sides of the partition 11; the first filtering channel 12 and the second filtering channel 13 are in mutual communication; an ultrafiltration filter element 14 is disposed in the filter housing 1, and the ultrafiltration filter element 14 and the first filtering channel 12 are disposed on the same side; sewage enters from the first filtering channel 12, is filtered by the ultrafiltration filter element 14, and then discharged from the second filtering channel 13, and the purified water enters from the second filtering channel 13, flushes the ultrafiltration filter element 14, and then is discharged from the first filtering channel 12.

[0033] In an optional embodiment, a first plugging member 15 is disposed in the first filtering channel 12, the first filtering channel 12 is provided with a first plugging seat 121, and a through hole 122 is formed in the side of the first plugging seat 121; a first spring 123 is disposed between the top of the first plugging seat 121 and the first plugging member 15. By providing a plurality of side through holes, preferably six, the water inflow and outflow on this side are greater and more thorough, and when backwashing, the water can be completely discharged.

[0034] In an optional embodiment, a first sealing ring 124 is disposed at the bottom of the first filtering channel 12, and the first plugging seat 121 and the first sealing ring 124 cooperate to form a seal.

[0035] A second plugging member 16 is disposed in the second filtering channel 13. The second filtering channel 13 includes a second plugging seat 131, and an opening is formed at the top of the second plugging seat 131; a plurality of axially distributed inner grooves 134 are formed on the side of the second plugging seat 131; a second spring 133 is disposed between the top of the second plugging seat 131 and the second plugging member 16. The inner grooves are preferably six. By providing the inner grooves, the water pressure of the water inflow and outflow on this side is greater.

[0036] A second sealing ring 132 is disposed at the inner bottom of the second filtering channel 13; the second plugging seat 131 and the second sealing ring 132 cooperate to form a seal.

[0037] Specific working process:

[0038] When the filter is pulled out of the machine base, the first plugging member and the second plugging member are both at the bottommost position and are tightly connected to the first seal and the second sealing ring respectively, preventing the water in the filter from leaking out.

[0039] When the filter is inserted into the machine base, the first pipe is a hollow pipe, and the bottom is used to connect the water pipe. There are two first pipes, corresponding to the first filter channel and the second filter channel respectively. When the filter is inserted into the filter mounting seat, the first pipes are respectively inserted into the first plugging seat and the second plugging seat, pushing up the first plugging member and the second plugging member, thus realizing water inlet and outlet.

[0040] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements or improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
