DETAILED DESCRIPTION

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides, for example Figures 1-4 The illustrated nozzle pump for filtering impurities and preventing clogging includes a bottle cap 1. A guide ring 2 is provided at the top of the bottle cap 1, and the bottom of the guide ring 2 is fixedly connected to the top of the bottle cap 1, communicating with the bottle cap 1. A sliding rod 3 is provided inside the guide ring 2, and a pipe is provided inside the sliding rod 3. The bottom end of the sliding rod 3 can pass through the guide ring 2 and slide up and down inside the bottle cap 1. A nozzle 4 is provided at the top of the sliding rod 3, and the bottom of the nozzle 4 is fixedly connected to the top of the sliding rod 3, with the nozzle 4 communicating with the pipe inside the sliding rod 3. A nozzle 5 is provided on the side of the nozzle 4, and the nozzle 5 communicates with the interior of the nozzle 4. The bottle cap 1 has a pump 6 at its bottom, with the top of the pump 6 fixedly connected to the bottom of the cap 1. The pump 6 is linked to the sliding rod 3. A hose 7 is connected to the bottom of the pump 6, and the hose 7 is connected to the pump 6. A filter head 8 is located at the bottom of the hose 7, connected to the bottom of the hose 7. The filter head 8 has a filter screen inside to filter out impurities. A positioning component is located above the guide ring 2. The positioning component is used to limit the depth of the nozzle 4 when pressed down, allowing the amount of liquid sprayed at one time to be selected according to needs, avoiding waste. The positioning component includes a fixing plate 9 and a screw cap 13. In use, pressing the nozzle 4 drives the sliding rod 3 to slide down, which in turn presses the pump 6. The pump 6, when pressed, draws the liquid, after filtering out impurities through the filter head 8, into the hose 7, then into the sliding rod 3, and finally sprays it out through the nozzle 5 on the left side of the nozzle 4.

[0024] like Figure 1 and Figure 2 As shown, a fixing plate 9 is provided above the guide ring 2. The diameter of the fixing plate 9 is the same as the maximum diameter of the guide ring 2. A through-hole circular groove 10 is provided in the center of the fixing plate 9. The diameter of the circular groove 10 is larger than the diameter of the inner ring of the guide ring 2. The fixing plate 9 is sleeved on the outside of the sliding rod 3 through the circular groove 10, and the bottom of the fixing plate 9 is fixedly connected to the top of the guide ring 2. Figure 2 and Figure 3 As shown, the side of the fixed plate 9 has a through threaded hole 11, and a screw 12 is screwed into the threaded hole 11. The right end of the screw 12 can be screwed into the circular groove 10. Figure 2 and Figure 3As shown, the right end of the screw rod 12 is provided with an arc-shaped plate 14, which can be attached to the inner wall of the circular groove 10. When the arc-shaped plate 14 is attached to the inner wall of the circular groove 10, the innermost side of the arc-shaped plate 14 will not exceed the inner annular surface of the guide ring 2. As shown Figure 3 As shown, the arc-shaped plate 14 is provided with a cavity 15 inside, and the left side of the arc-shaped plate 14 is provided with an opening. The cavity 15 is provided with a limiting disc 16, which can only rotate in the cavity 15. The right end of the screw rod 12 passes through the opening on the left side of the arc-shaped plate 14 and enters the cavity 15, and the right end of the screw rod 12 is fixedly connected to the left end of the limiting disc 16. At this time, the rotation of the screw rod 12 will push the arc-shaped plate 14 to move, but the screw rod 12 will not rotate the arc-shaped plate 14. As shown Figure 2 and Figure 3 As shown, the left end of the screw rod 12 is provided with a screw cap 13, which is located on the left side of the fixed disc 9. The screw cap 13 is fixedly connected to the left end of the screw rod 12, and the screw cap 13 can drive the screw rod 12 to rotate by rotating. As shown Figure 3 As shown, the left side of the arc-shaped plate 14 is provided with a circular rod 17, the right end of which is fixedly connected to the left side of the arc-shaped plate 14. The circular rod 17 is located above the screw rod 12, and the inner wall of the circular groove 10 is provided with a corresponding sliding groove 18. The circular rod 17 can slide in the sliding groove 18, and the circular rod 17 and the sliding groove 18 can make the movement of the arc-shaped plate 14 more stable. As shown Figure 2 and Figure 3 As shown, the uppermost end of the rod body of the sliding rod 3 is sleeved with a first blocking ring 19, which is located at the bottom of the nozzle 4. The top of the first blocking ring 19 is fixedly connected to the bottom of the nozzle 4, and the maximum diameter of the first blocking ring 19 is smaller than the inner annular diameter of the guide ring 2. Therefore, when the arc-shaped plate 14 is attached to the inner wall of the circular groove 10, the first blocking ring 19 can move downward to pass through the circular groove 10 and slide into the guide ring 2. The bottom of the first blocking ring 19 is provided with a second blocking ring 20, which is sleeved on the sliding rod 3, and the top of the second blocking ring 20 is fixedly connected to the bottom of the first blocking ring 19. The maximum diameter of the second blocking ring 20 is smaller than the maximum diameter of the first blocking ring 19. The bottom of the second blocking ring 20 is provided with a third blocking ring 21, which is sleeved on the sliding rod 3, and the top of the third blocking ring 21 is fixedly connected to the bottom of the second blocking ring 20. The maximum diameter of the third blocking ring 21 is smaller than the maximum diameter of the second blocking ring 20. In use, the position of the arc-shaped plate 14 can be adjusted by rotating the screw cap 13 according to the amount of spraying required. When the position of the arc-shaped plate 14 blocks the third blocking ring 21, the distance of the nozzle 4 pressing downward is the shortest, and the liquid sprayed by pressing is the least. In this way, according to the blocking of the arc-shaped plate 14 to different blocking rings, the distance of the nozzle 4 pressing downward can be adjusted, so that the amount of single spraying can be adjusted according to the requirement, which avoids waste and improves convenience.

[0025] It should be pointed out finally that the above only for the preferred embodiments of the present application and is not intended to limit the present application, although the foregoing embodiments of the present application have been described in detail, for those skilled in the art, it still can be modified for the foregoing each embodiment of the technical solutions recorded, or for some of the technical features of the equivalent replacement, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, should be included within the scope of the present application.
