[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than 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 efforts belong to the scope of protection of the present utility model.

[0018] The following will further describe the present utility model in conjunction with the accompanying drawings of the specification.

[0019] The present utility model provides the following technical solutions:

[0020] As shown in the Figures 1-3 accompanying drawings, the present utility model discloses a liquid storage tank with adjustable liquid discharge amount, which includes a tank body 1. A liquid discharge end 2 is provided at the bottom of the tank body 1. A liquid discharge port 3 is opened on the liquid discharge end 2. An adjusting sliding cover 4 is provided on the liquid discharge end 2. A sliding connection structure is provided between the adjusting sliding cover 4 and the liquid discharge end 2. The sliding connection structure includes a chute 5 opened on the adjusting sliding cover 4 and a guide rail portion 6 provided on the liquid discharge end 2. The guide rail portion 6 extends into the chute 5 to be connected with the adjusting sliding cover 4. The adjusting sliding cover 4 slides on the liquid discharge end 2 along the guide rail portion 6, and the opening degree of the liquid discharge port 3 is adjusted during the sliding process of the adjusting sliding cover 4. Specifically, in this design, by providing the adjusting sliding cover 4 on the liquid discharge end 2, the chute 5 on the adjusting sliding cover 4 can be slidably matched with the guide rail portion 6 on the liquid discharge end 2, so as to realize the precise adjustment of the opening degree of the liquid discharge port 3. The user only needs to gently push the adjusting sliding cover 4 to adjust the opening degree of the liquid discharge port 3 according to actual needs, and then control the liquid discharge amount of the liquid storage tank. In addition, in order to further improve the adjustment accuracy of the liquid discharge amount and the convenience of operation, scale lines are also provided on the adjusting sliding cover 4. These scale lines clearly mark the opening degrees of the liquid discharge port 3 at different positions, and the user can quickly adjust according to the scale lines without going through a cumbersome trial-and-error process.

[0021] Furthermore, the guide rail portion 6 is provided on the opposite end faces on both sides of the liquid discharge end 2 far away from the inside of the tank body 1. A plurality of positioning holes 7 are opened on the guide rail portion 6, and the positioning holes 7 are arranged at equal intervals along the length direction of the guide rail portion 6. The adjusting sliding cover 4 is provided with limiting holes 8 corresponding to the positioning holes 7, and a positioning pin 9 is provided between the positioning holes 7 and the limiting holes 8 to limit the position of the adjusting sliding cover 4 on the guide rail portion 6. Specifically, in this embodiment, the design of the positioning holes 7 and the limiting holes 8 enables the position of the adjusting sliding cover 4 on the guide rail portion 6 to be accurately locked. The user can fix the adjusting sliding cover 4 at a specific position by inserting the positioning pin 9 into the corresponding positioning holes 7 and limiting holes 8, so as to ensure the stability of the opening degree of the liquid discharge port 3.

[0022] Further, a sealing cushion block is arranged between the groove wall of the sliding groove 5 and the guide rail portion 6. The sealing cushion block includes a first sealing cushion block 10 and a second sealing cushion block 11. The first sealing cushion block 10 and the second sealing cushion block 11 are symmetrically arranged on both sides of the sliding groove 5. A sealing groove 12 is formed in the sealing cushion block. The guide rail portion 6 extends into the sealing groove 12 and is in sealing connection with the sealing cushion block. A sealing through hole 13 corresponding to the positioning hole 7 and the limiting hole 8 is formed in the sealing cushion block. The positioning pin 9 sequentially passes through the limiting hole 8 and the sealing through hole 13 and extends into the positioning hole 7 to fix the adjusting sliding cover 4 and the guide rail portion 6. Specifically, in this embodiment, the design of the sealing cushion block effectively ensures the sealing performance of the adjusting sliding cover 4 during the sliding process, and avoids the leakage of liquid from the gap between the liquid outlet end 2 and the adjusting sliding cover 4 during the adjustment process. The symmetrical arrangement of the first sealing cushion block 10 and the second sealing cushion block 11 enables the adjusting sliding cover 4 to obtain good sealing effects on both sides. The formation of the sealing groove 12 ensures that the guide rail portion 6 can completely extend into and closely fit with the sealing cushion block, and the design of the sealing through hole 13 allows the positioning pin 9 to smoothly extend into the positioning hole 7 after passing through the limiting hole 8, realizing the fixed connection between the adjusting sliding cover 4 and the guide rail portion 6.

[0023] Further, the guide rail portion 6 is arranged on the liquid outlet end 2 in an inclined structure. The inclined direction of the guide rail portion 6 is that the liquid outlet end 2 is inclined towards the side away from the center of the tank body 1 at the upper part of the tank body 1. The sliding opening direction of the adjusting sliding cover 4 on the guide rail portion 6 for the liquid outlet 3 is that the adjusting sliding cover 4 slides towards the upper part of the liquid outlet end 2. Specifically, in this embodiment, the inclined structure design of the guide rail portion 6 enables the adjusting sliding cover 4 to more conveniently control the opening degree of the liquid outlet 3 during sliding. When the user needs to increase the liquid discharge amount, just gently push the adjusting sliding cover 4 towards the upper part of the liquid outlet end 2, and the liquid outlet 3 can be gradually opened; on the contrary, when the user needs to reduce the liquid discharge amount, just slide the adjusting sliding cover 4 downward, and the liquid outlet 3 will gradually close. This design is not only easy to operate, but also can ensure that the opening degree of the liquid outlet 3 changes smoothly during the adjustment process, thereby realizing the precise control of the liquid discharge amount. In addition, the design of the inclined guide rail portion 6 helps to prevent the formation of eddy currents or dead corners of the liquid in the liquid storage tank, thereby ensuring the uniform distribution of the liquid in the tank body 1, avoiding the uneven flow phenomenon of the liquid during the liquid discharge process, and also being able to prevent the liquid from remaining between the adjusting sliding cover 4 and the liquid outlet end 2 after the liquid discharge is completed.

[0024] Further, the adjusting sliding cover 4 is made of stainless steel. The two ends of the adjusting sliding cover 4 are respectively an opening part 14 and a closing part 15. The closing part 15 is arranged at the upper part of the adjusting sliding cover 4, and the closing part 15 is in close fit with the liquid outlet end 2 of the tank body 1. Specifically, in this embodiment, the adjusting sliding cover 4 is made of stainless steel, which not only ensures its durability and can withstand a certain degree of extrusion and friction, but also the stainless steel material has good corrosion resistance and can operate stably for a long time in various environments. In addition, the thermal conductivity of stainless steel is also relatively low, which helps to maintain the temperature stability of the adjusting sliding cover 4 and avoid affecting the accuracy of the liquid output volume due to temperature changes during the adjustment process. The two ends of the adjusting sliding cover 4 are respectively designed as an opening part 14 and a closing part 15. The closing part 15 is located at the upper part of the adjusting sliding cover 4 and is in close fit with the liquid outlet end 2 of the tank body 1. This design ensures that the adjusting sliding cover 4 can completely seal the liquid outlet 3 in the closed state, preventing liquid leakage when liquid output is not required. At the same time, the close fit of the closing part 15 can also effectively prevent external impurities from entering the inside of the tank body 1 and ensure the purity of the liquid inside the liquid storage tank.

[0025] Further, the sealing cushion block is made of elastic rubber material, and the sealing cushion block is in interference fit with the guide rail part 6 and the groove wall of the sliding groove 5 respectively. Specifically, in this embodiment, the sealing cushion block is made of elastic rubber material. This material not only has good sealing performance, but also can undergo elastic deformation within a certain range to adapt to the possible small position changes during the sliding process of the adjusting sliding cover 4. Through the interference fit with the guide rail part 6 and the groove wall of the sliding groove 5, the sealing cushion block can form a tight sealing layer between the adjusting sliding cover 4 and the liquid outlet end 2, effectively preventing liquid from leaking from the gap during the adjustment process.

[0026] Further, the outer diameter of the positioning pin 9 is larger than the inner diameter of the sealing through hole 13, and the positioning pin 9 is in interference fit with the sealing cushion block. Specifically, in this embodiment, the outer diameter of the positioning pin 9 is designed to be slightly larger than the inner diameter of the sealing through hole 13, ensuring that when the positioning pin 9 passes through the sealing through hole 13 and extends into the positioning hole 7, an interference fit will be formed between the positioning pin 9 and the sealing cushion block. This interference fit not only enhances the connection stability between the positioning pin 9 and the sealing cushion block, but also further improves the sealing performance of the adjusting sliding cover 4 during the sliding process. When the positioning pin 9 is inserted, the sealing cushion block will be subjected to a certain degree of extrusion deformation, so as to fit more tightly between the adjusting sliding cover 4 and the guide rail part 6, forming an almost gapless sealing structure. This design not only ensures the sealing performance of the adjusting sliding cover 4 in the fixed position, but also can effectively prevent liquid from flowing out of the gap between the liquid outlet end 2 and the adjusting sliding cover 4 during the adjustment process. A jacking groove 16 is opened at the bottom end or the top end of the positioning pin 9, and the jacking groove 16 is used to jack out the positioning pin 9 from the hole by an external tool to achieve adjustment.

[0027] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to the embodiments shown herein, but rather to the broadest scope consistent with the principles and novel features disclosed herein.
