DETAILED DESCRIPTION
[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.
[0020] Please refer to Figures 1-4The utility model provides a technical scheme: an experimental bottle, including bottle body 1, the top port place threaded cover of bottle body 1 is equipped with bottle cap 2, is installed with the elbow pipe 3 on bottle cap 2, the bottom end intercommunication of elbow pipe 3 has the hose 7, and the hose 7 is inserted into bottle body 1, and the elbow pipe 3 is connected with the drop head 4 through the connecting assembly 6, and the top of bottle cap 2 is connected with the spray head 5 through the connecting assembly 6.
[0021] Connecting assembly 6 includes fixed seat 601, outer thread pipe 602, inner thread pipe 603, fixed seat 601 is fixedly installed at the top of bottle cap 2, outer thread pipe 602 is fixedly installed on the connecting end of drop head 4, spray head 5, inner thread pipe 603 is fixedly installed on the connecting end of elbow pipe 3, the inner diameter of fixed seat 601, inner thread pipe 603 is identical, and the inner thread of fixed seat 601, inner thread pipe 603 is identical, and outer thread pipe 602 is screwed in the inner thread pipe 603 on drop head 4, and outer thread pipe 602 is screwed in fixed seat 601 on spray head 5, set replaceable drop head 4, spray head 5, for selecting water mode according to use condition, and one unnecessary drop head 4 or spray head 5 is fixed through connecting assembly 6, need not to place additionally, adopt the mode of screw connection to install drop head 4 or spray head 5 on elbow pipe 3, it is convenient and fast.
[0022] The bottom inner wall of bottle body 1 is inclinedly arranged, and the lowest point is located directly below the bottom end of elbow pipe 3, the bottom end of hose 7 extends to the lowest point, the inclined bottom structure utilizes gravity to naturally guide the liquid in bottle body 1 to the lowest point, ensures that the liquid is as much as possible to be collected in the area accessible to hose 7, avoids residue, and the bottom end of hose 7 is aligned with the lowest point, which can ensure that the liquid can still be effectively extracted when the liquid is reduced to the limit, improving resource utilization.
[0023] The inner wall of the fixed seat 601 is fixedly provided with a sealing gasket 1, and the inner wall of the inner threaded pipe 603 is fixedly provided with a sealing gasket 2. The elasticity and sealing effect of the sealing gasket 1 and the sealing gasket 2 can cause the sealing gasket 1 and the sealing gasket 2 to be elastically deformed due to extrusion as the thread is gradually tightened. The deformation enables the sealing gasket to tightly fit the pipe wall of the outer threaded pipe 602 and the inner threaded pipe 603, thereby forming a tight barrier between the two, effectively preventing liquid from leaking out or leaking from the connection between the outer threaded pipe 602 and the inner threaded pipe 603. In addition, the elasticity of the sealing gasket 1 plays another important role in the connection between the outer threaded pipe 602 and the fixed seat 601. When the outer threaded pipe 602 is screwed into the fixed seat 601, the sealing gasket 1 will generate a counterforce while being extruded. This counterforce can not only fill the tiny gap between the outer threaded pipe 602 and the fixed seat 601, but also provide a force for the outer threaded pipe 602 to tightly fit the inside of the fixed seat 601, thereby making the connection between the outer threaded pipe 602 and the fixed seat 601 more stable and greatly enhancing the stability of the entire connection structure.
[0024] The bending pipe 3 is rotationally connected with the bottle cap 2, and can be rotated according to the use requirement to adjust the direction of the bending pipe 3. A sealing ring 8 is rotationally arranged at the connection between the bending pipe 3 and the bottle cap 2, and is fixedly installed on the bottle cap 2. Since the sealing ring 8 is located at the rotation gap between the bending pipe 3 and the bottle cap 2, when the bending pipe 3 rotates around the connection point with the bottle cap 2, the sealing ring 8 can tightly fit the outer wall of the bending pipe 3 by virtue of its elasticity. Even if the position of the bending pipe 3 changes slightly during rotation, the sealing ring 8 can also elastically deform to maintain tight contact with the outer wall of the bending pipe 3, thereby effectively preventing liquid from leaking from the rotation connection between the bending pipe 3 and the bottle cap 2. In addition, the presence of the sealing ring 8 can also play a role in buffering and noise reduction to some extent. When the bending pipe 3 rotates, it may rub against the bottle cap 2. The sealing ring 8 can reduce the wear caused by this friction, thereby prolonging the service life of the connection structure of the bending pipe 3 and the bottle cap 2.
[0025] A plastic one-way valve 11 is fixedly installed on the top of the bottle cap 2, and the bottom end of the plastic one-way valve 11 extends into the bottle body 1. When the bottle body 1 is squeezed, the air flow in the bottle body 1 cannot pass through the plastic one-way valve 11. At this time, the air will squeeze the liquid in the bottle body 1 into the bending pipe 3 from the hose 7, so that the liquid can flow out from the drop head 4 or the spray head 5 connected with the bending pipe 3. After the bottle body 1 is loosened, the bottle body 1 returns to its original shape. At this time, external air can enter the bottle body 1 from the plastic one-way valve 11, which can effectively prevent the liquid in the bending pipe 3 from flowing back into the bottle body 1 and thereby contaminating the liquid in the bottle body 1.
[0026] The outer wall of the bottle body 1 is provided with scales 12, which are provided with two places and symmetrically distributed on the bottle body 1. The scales 12 are used to observe the remaining amount of liquid in the bottle body 1, and to increase the friction on the palm to avoid the bottle body 1 from falling due to hand slipping when holding the bottle body 1.
[0027] Working principle: when in use, after the bottle cap 2 is unscrewed, liquid is added into the bottle body 1. According to the use requirement, the outer threaded pipe 602 on the dripping head 4 or the spraying head 5 is screwed into the inner threaded pipe 603, so that the bending pipe 3 is communicated with the dripping head 4 or the spraying head 5. The unused spraying head 5 or dripping head 4 is screwed into the fixed seat 601, then the bottle body 1 is squeezed to deform, the liquid in the bottle body 1 is squeezed into the bending pipe 3 from the hose 7, then the liquid enters the dripping head 4 or the spraying head 5 from the bending pipe 3, and then flows out from the port of the dripping head 4 or the spraying head 5. After the bottle body 1 is loosened, the bottle body 1 restores the deformation, and at this time, the external air can enter the bottle body 1 from the plastic one-way valve 11.
[0028] Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor belong to the scope of protection of the utility model.
