Description

[Technical field]

[0001] The invention relates to an underwater bearing-free, scale-proof and anti-blocking ultra-quiet pump. [Background technology]

[0002] In order to meet the drinking water needs of pets and provide them with a high-quality drinking experience, pet drinking fountains were developed and have become an important part of pet health.

[0003] At present, some pet drinking fountains on the market generally use submersible pumps to drive water circulation. The core structure is that the motor drives the impeller to rotate and drive the water in the water tank, and pumps the water in the water tank out to the water tray for pets to drink. Although it can provide drinking water for pets, there are still problems. In the design of traditional submersible pumps, the bearings work underwater. For example, the water remaining in the water tank for a long time is easy to breed bacteria and form a sticky biofilm, adsorbing food residues, dust particles and scale such as calcium and magnesium deposits. These impurities will gradually accumulate between the rotating shaft and the bearing of the submersible pump, resulting in increased friction or even stuck, and finally causing a stall failure. In addition, the existing submersible pumps have a single function and lack a certain filtering function. They can only pump the water in the water tank to the water tray for pets to drink, and cannot pre-filter the water in the water tank. The safety of pets' drinking water cannot be guaranteed.

[0004] Therefore, the present invention is just produced based on the above shortcomings. [Summary of the invention]

[0029] The present invention will be further described below in conjunction with the accompanying drawings:

[0030] like Figures 1 to 5 As shown, an underwater bearingless anti-scale and anti-blocking ultra-silent pump comprises an underwater pump body 1 which can be extended into the water and an above-water pump body 2 which can be placed on the water surface, a motor cavity 21 being provided in the above-water pump body 2, a water inlet cavity 11 and a filter cavity 13 which is arranged between the water inlet cavity 11 and the motor cavity 121 and is connected to the water inlet cavity 11 being provided in the underwater pump body 1, one side of the filter cavity 13 is open, a filter device 3 which can filter and discharge water is provided at the opening of the filter cavity 13, a motor 4 is provided in the motor cavity 21, a motor shaft 41 with one end passing through the filter cavity 13 and then penetrating into the water inlet cavity 11 is provided on the motor 4, a sealing sleeve 30 which can be relatively rotatably mounted on the motor shaft 41 and isolates the filter cavity 13 from the motor cavity 21 is provided on the above-water pump body 2, an impeller 5 for pumping water into the water inlet cavity 11 and discharging it through the filter device 3 is provided on the motor shaft 41 in the water inlet cavity 11 Specifically, the motor 4 is a brushless motor, which has a bearing inside that supports the motor shaft 41 so that it can maintain stable rotation inside the brushless motor; the sealing sleeve 30 is a silicone oil seal, which can prevent water from entering the inside of the motor and also plays a shock-absorbing role; the underwater pump body 1 is also provided with a water inlet 10 that is connected to the water inlet chamber 11 to supply water into the water inlet chamber 11.

[0031] When the present invention is used, the underwater pump body 1 is inserted underwater and the above-water pump body 2 is placed on the water surface, so that the motor 4 is located on the water surface when working, and the motor shaft 41 drives the impeller 5 to rotate, and the impeller 5 draws water from the water inlet 10 into the water inlet chamber 11. After passing through the filter chamber 13 connected to the water inlet chamber 11, the impeller 3 removes impurities and dirt in the water and then discharges it. The present invention uses the long shaft of the motor to pass through the sealing sleeve and the filter chamber and directly extend to the water inlet chamber to drive the impeller to rotate. No bearings are set in the water inlet chamber and the filter chamber, and the impeller is directly driven by the long shaft of the brushless motor. Since there is no bearing underwater, the problem of stalling caused by the accumulation of scale, bacterial film and impurities between the shaft and the bearing is avoided, and a filtering device is also provided at the opening of the filter chamber for filtering impurities. In this way, the water in the water tank is pre-filtered before the water pump in the water tank is sent to the water tray for the pet to drink, which fully ensures the safety of the pet's drinking water.

[0032] Specifically, the water inlet chamber 11 is arranged at the bottom of the underwater pump body 1, the filter chamber 13 is arranged above the water inlet chamber 11, and the motor chamber 21 is located on one side of the filter chamber 13. The three are generally arranged linearly, so that the long axis of the motor can pass through the motor chamber 21, the filter chamber 13 and the water inlet chamber 11 in sequence.

Specifically, the bottom wall of the mounting groove 312 is an Ω-shaped wall, and a plurality of filter holes 311 are distributed on the bottom wall. After water enters the water inlet chamber 11, it passes through the filter chamber 13 connected to the water inlet chamber 11, and enters the mounting groove 312 through the filter holes 311 on the filter cover 31, and is further filtered by the filter cotton 32 in the mounting groove 312 to remove impurities and dirt in the water, and then is discharged from the opening of the mounting groove 312 to achieve circulating filtration of water.

Specifically, a card slot 61 is provided on both sides of the shock-absorbing pad 6, and the two ends of the bracket on the motor 4 are inserted into the card slot 61 to fix the motor 4 on the shock-absorbing pad 6. The shock-absorbing pad 6 is made of silicone material. Further, one end of the motor cavity 21 is open, and a top cover 18 covering the opening can be detached at the opening of the motor cavity 21. The top cover 18 is provided with a pressing part 181 that presses the shock-absorbing pad into the motor cavity 21 when the top cover 18 is installed at the opening. Specifically, the pressing part 181 is a plurality of pillars provided at the bottom of the top cover 18. The top cover 18 can be fixed to the pump body 1 by screws 20 passing through the pillars, and the top of the top cover 18 also has a label 40 that covers the screw holes and screws. The vibration generated by the operation of the motor 4 will be buffered by the shock-absorbing pad 6, and the pressing part 181 presses the shock-absorbing pad 6 into the motor cavity 21, effectively reducing the vibration and noise generated by the operation of the motor.
