[0020] The embodiments of the present application will be described in detail below with reference to the drawings. It should be clear that the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0021] As shown in Figures 1-4 , an adjustable quantitative disinfectant pressing device is provided, comprising: a bottle body 100 and a pressing pump head. The pressing pump head is arranged at the bottle mouth of the bottle body 100, and is used for pressing out liquid.

[0022] The bottle body 100 is made of transparent or translucent plastic material, which is not only light and portable, but also can allow the user to directly observe the remaining amount of disinfectant in the bottle, so as to timely supplement or replace the disinfectant. The bottle body 100 can be designed as a cylindrical, square or other shape convenient to hold, and the bottle mouth has external threads for mating connection with the internal threads of the pressing pump head. Preferably, the bottom of the bottle body 100 can be provided with a non-slip pad to increase the stability of the bottle body 100 on the desktop and prevent accidental falling during use.

[0023] The pressing pump head comprises a storage cylinder 200, a piston 300, a dosing cavity cylinder 400, an adjusting gland 500, an adjusting knob 600, a bottle mouth cover 700, a pressing head 800, a piston rod 900, a top-side one-way ball valve 1000, a bottom-side one-way ball valve 1100, a liquid guide pipe 1200, and a spring 1300.

[0024] The bottle mouth cover 700 is a lower opening cylindrical shell, and an inner thread is formed on the inner wall of the shell. The bottle mouth cover 700 is arranged at the top end of the storage cylinder 200. After the bottle body 100 is assembled with the pressing pump head, the bottle mouth cover 700 is threadedly connected with the bottle body 100 and fixed at the bottle mouth of the bottle body 100, and the storage cylinder 200 is located in the bottle mouth of the bottle body 100.

[0025] The dosing cavity cylinder 400 is arranged in the storage cylinder 200 and can contain a certain amount of disinfectant. The output amount of the disinfectant in one time can be controlled by moving the adjusting gland 500. The piston 300 is arranged in the dosing cavity cylinder 400 and can move up and down along the axial direction of the dosing cavity cylinder 400. When the piston 300 moves upward, the liquid in the bottle body 100 enters the dosing cavity cylinder 400. When the piston 300 moves downward, the liquid in the dosing cavity cylinder 400 is discharged from the pressing head 800. The adjusting gland 500 is located above the piston 300, and the adjusting gland 500 is threadedly connected with the dosing cavity cylinder 400. The threadedly connected form enables a user to adjust the depth of the adjusting gland 500 embedded in the dosing cavity cylinder 400 by rotating the adjusting gland 500. Specifically, when the adjusting gland 500 is rotated downward, the embedding depth is increased, and the highest position point of the piston 300 in the storage cylinder 200 is also lowered, thereby reducing the volume of the disinfectant that can be actually contained in the dosing cavity cylinder 400, that is, the output amount of the disinfectant in one time is reduced. Conversely, when the adjusting gland 500 is rotated upward, the embedding depth is reduced, and the highest position point of the piston 300 is moved upward, thereby increasing the volume of the disinfectant that can be actually contained in the dosing cavity cylinder 400, so that the output amount of the disinfectant in one time is increased.

[0026] By rotating the adjusting gland 500, a user can accurately control the output amount of the disinfectant according to actual needs, thereby avoiding the inconvenience and waste caused by the fixed output amount of the disinfectant in the traditional pressing pump head. Since the output amount of the disinfectant can be adjusted, the present application can be applied to different use scenarios, such as medical places, families, public places, and the like, to meet different needs of disinfectant use amount in different occasions. The design of the adjusting gland 500 is simple and easy to operate, which not only ensures good sealing performance, but also enables a user to easily adjust without complex operation, thereby improving the use convenience.

[0027] The adjusting gland 500 comprises a positioning sleeve column 510, an identification disc 520, and a reference ring shell 530.

[0028] The upper half of the positioning sleeve column 510 is located outside the bottle body, facilitating user operation adjustment. The lower half of the positioning sleeve column 510 is provided with external threads on the surface, and the upper end of the dosing cavity cylinder 400 is provided with internal threads matching the external threads of the positioning sleeve column 510, so that the lower end of the positioning sleeve column 510 is screwed into the dosing cavity cylinder 400 and the depth of the positioning sleeve column 510 is adjusted by the threads, thereby adjusting the highest position of the piston 300 in the storage cylinder 200 and controlling the volume of the sterilizing liquid in the dosing cavity cylinder 400.

[0029] The identification disc 520 is arranged at the top end of the positioning sleeve column 510, and the identification disc 520 is spaced apart from the upper surface of the bottle cap 700 by a certain distance to ensure that the identification disc 520 has sufficient space to drop when the positioning sleeve column 510 rotates downward. The reference ring shell 530 is arranged on the bottle cap 700 and covers the outside of the identification disc 520. The side surface of the identification disc 520 is provided with a scale line for displaying different liquid discharge amounts.

[0030] When the positioning sleeve column 510 rotates upward / downward, the identification disc 520 rotates upward / downward together, and the reference ring shell 530 remains stationary on the bottle cap 700. Therefore, the top edge of the reference ring shell 530 can be used as a reference line. As the depth of the positioning sleeve column 510 changes, the scale line on the identification disc 520 will be aligned with the top edge of the reference ring shell 530 in turn, so that the user can know the volume of the sterilizing liquid in the dosing cavity cylinder 400, such as 1ml, 2ml, 5ml, 10ml, 15ml, 20ml, etc., facilitating the user to intuitively adjust the required liquid discharge amount.

[0031] Without complex calculations or tools, the user only needs to rotate the identification disc 520 to the required scale line aligned with the top edge of the reference ring shell 530. The user can quickly set the required liquid discharge amount, and the operation is simple and fast, reducing the operation time and improving the accuracy and convenience of use.

[0032] The positioning sleeve column 510 and the identification disc 520 are provided with through grooves for the piston rod 900 to pass through. The pressure head 800 is connected to the top end of the piston rod 900, and the bottom end of the piston rod 900 is connected to the piston 300 after passing through the adjusting gland 500. When the pressure head 800 is pressed, the piston 300 is pushed downward by the piston rod 900, thereby discharging the sterilizing liquid in the dosing cavity cylinder 400.

[0033] The adjusting knob 600 is arranged on the top of the adjusting gland 500, and is used to drive the adjusting gland 500 to rotate and limit the pressure head 800. The upper surface of the identification disc 520 is provided with a groove 540 for accommodating the adjusting knob 600 in the storage state. The adjusting knob 600 is composed of a connecting rod 610 and a clamping fork 620. One end of the connecting rod 610 is hinged in the groove 540, so that the adjusting knob 600 can rotate in the groove 540. The clamping fork 620 is provided with a clamping groove 630 matched with the pressure head 800, and the other end of the clamping fork 620 is hinged with the other end of the connecting rod 610.

[0034] When the adjusting knob 600 is in the storage state, the connecting rod 610 and the clamping fork 620 are fitted and folded in the groove 540, so that the adjusting knob 600 does not occupy extra space when not in use, and the overall compactness of the pressing pump head is maintained. When it is necessary to adjust the liquid output of the disinfectant, the user can turn the adjusting knob 600 out of the groove 540, so that it is out of the storage state, but the connecting rod 610 and the clamping fork 620 are still in the fitted state. At this time, the adjusting knob 600 can be rotated by rotating the adjusting knob 600. In the transportation process, in order to prevent the pressure head 800 from being accidentally pressed to squeeze out the disinfectant, the user can unfold the connecting rod 610 and the clamping fork 620. After unfolding, the clamping groove 630 of the clamping fork 620 can clamp the pressure head 800, so that the pressure head 800 is embedded in the clamping groove 630, and the vertical limiting of the pressure head 800 is realized, which prevents the pressure head 800 from being accidentally pressed due to vibration or other reasons in the transportation process, and ensures the sealing and safety of the disinfectant.

[0035] The piston rod 900 is provided with a first channel 910 communicated with the piston 300, that is, the piston rod 900 is provided with a channel, the piston 300 is provided with a channel, and the two channels are communicated and jointly constitute the first channel 910. The pressure head 800 is provided with a second channel 920 communicated with the first channel 910. The top one-way ball valve 1000 is arranged in the top channel of the first channel 910. The liquid conduit 1200 is connected with the bottom end of the storage cylinder 200, and the bottom one-way ball valve 1100 is arranged in the lower end of the storage cylinder 200. The spring 1300 is arranged in the quantitative cavity 400.

[0036] When the pressure head 800 is pressed downward, the piston 300 is pushed to move downward by the piston rod 900, the air pressure in the dosing cavity cylinder 400 is increased, the top one-way ball valve 1000 is opened, and the gas is discharged from the pressure head 800. When the pressure head 800 is released, the piston 300 is pushed to move upward by the spring 1300, the dosing cavity cylinder 400 is in a negative pressure state, the bottom one-way ball valve 1100 is opened, and the liquid in the bottle body 100 enters the storage cylinder 200 through the liquid conduit 1200. When the pressure head 800 is pressed downward again, the piston 300 moves downward, the top one-way ball valve 1000 is opened, and the disinfecting liquid in the dosing cavity cylinder 400 is discharged in sequence through the first passage 910 and the second passage 920, so that the disinfecting liquid in the dosing cavity cylinder 400 is discharged.

[0037] The above merely illustrates the specific implementation of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of the changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
