Description

Technical Field

[0001] This utility model relates to the field of hygiene and disinfection technology, specifically to a device for precisely controlling the dosage of disinfectant solution. Background Technology

[0002] Disinfectant is a chemical substance that can kill or inhibit microorganisms. Spraying disinfectant in hospitals or other places where bacteria are prone to grow can effectively prevent the spread of diseases and the occurrence of bacterial infections. The ratio and dosage of disinfectant vary depending on the occasion.

[0003] In daily life, it is sometimes necessary to use disinfectant to disinfect tableware, clothing, or other frequently used items. In this case, it is necessary to mix it with water and strictly control the concentration of the disinfectant. However, the current disinfectant can only be poured out of the bottle and then mixed with water, making it difficult to control the amount of disinfectant poured out. If a measuring cup is used to measure the disinfectant, it will cause contamination of the poured disinfectant. When too much disinfectant is poured out, it will result in waste. Utility Model Content

[0004] In view of the shortcomings of the prior art, the present invention provides a device for accurately controlling the dosage of disinfectant, which solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: a device for accurately controlling the dosage of disinfectant, comprising: a locking cap, a storage bottle installed at the bottom of the locking cap, a metering tube provided in the middle of the locking cap, a pressure handle slidably provided inside the metering tube, an adjustment handle sleeved on the pressure handle, a pressure spring attached to the bottom of the adjustment handle, the bottom of the pressure spring sleeved on the metering tube, a suction tube provided at the bottom of the metering tube, an outlet connected to the side of the metering tube, and the end of the outlet away from the metering tube being connected to the outside of the storage bottle via the locking cap;

[0006] The quantitative tube includes a tube body, with a single-pass tube integrally provided at the bottom end of the tube body. A ball plug is provided inside the single-pass tube, and a second spring is attached to the ball plug. The top of the second spring is attached to the bottom of the tube body. The liquid outlet is connected to the side of the single-pass tube, and the liquid suction tube is connected to the single-pass tube directly below the ball plug. A liquid passage hole is provided in the middle of the bottom end of the tube body.

[0007] Preferably, the liquid outlet includes a liquid-pressing pipe, the end of which is provided with a nozzle, a baffle is provided inside the nozzle, a liquid outlet groove is formed in the middle of the baffle, a sealing plug is overlapped inside the liquid outlet groove, a connecting rod is provided at one end of the sealing plug located inside the nozzle, the connecting rod passes through the baffle and is provided with a slide to slide inside the nozzle, and a first spring is sleeved on the connecting rod between the nozzle and the baffle.

[0008] Preferably, the sealing plug is made of rubber.

[0009] Preferably, the inner wall of the liquid outlet tank is funnel-shaped, and the shape of the side of the sealing plug is adapted to the inner wall of the liquid outlet tank.

[0010] Preferably, the sealing plug has multiple sets of spray holes evenly distributed on its surface near the outer edge.

[0011] Preferably, a mounting ring is sleeved on the outer edge of the tube body, the mounting ring is disposed on the lock cover, and the bottom end of the compression spring overlaps the mounting ring.

[0013] Preferably, the adjusting handle includes a pressure ring, the pressure ring having a groove in its middle, the groove being rotatably fitted onto the pressure handle, a bracket being provided on the pressure ring, and an inner threaded sleeve being provided on the top of the bracket, the inner threaded sleeve being threaded onto the pressure handle.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This device for precisely controlling the dosage of disinfectant solution allows for adjustment of the amount of disinfectant solution dispensed. When the amount of disinfectant solution dispensed needs to be adjusted, the adjusting handle is turned to control its position on the pressure handle. When the pressure handle is pressed down, the adjusted handle will be directly locked at a certain height, so that only the predetermined amount of disinfectant solution can be dispensed from the metering tube. This achieves the effect of adjusting the amount of disinfectant solution dispensed, avoiding the waste caused by pouring out disinfectant solution and measuring the dosage with a measuring cup.

[0016] 2. This device for precisely controlling the dosage of disinfectant uses an adjusting handle fitted onto the pressure handle. A spring between the adjusting handle and the metering tube provides an upward thrust to the adjusting handle, causing the pressure handle to move upward. When the user carries the device, rotating the adjusting handle depresses the spring, which, in conjunction with the spring's pressure, gradually locks the pressure handle in place, preventing accidental contact or squeezing while carrying the device. It also prevents accidental use by children, thus improving the safety of disinfectant use.

[0017] 3. This device for precisely controlling the dosage of disinfectant solution has an outlet that is sealed with a plug, ensuring that the outlet remains closed when the device is not in use. This isolates the disinfectant solution from the outside environment and prevents cross-contamination of unused disinfectant solution. Attached Figure Description

[0026] 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.

[0027] Please see Figure 1-7A device for precisely controlling the dosage of disinfectant includes: a locking cap 1, a storage bottle 5 installed at the bottom of the locking cap 1, a metering tube 7 provided in the middle of the locking cap 1, a pressure handle 2 slidably provided inside the metering tube 7, an adjusting handle 3 sleeved on the pressure handle 2, a pressure spring 6 attached to the bottom of the adjusting handle 3, the bottom of the pressure spring 6 sleeved on the metering tube 7, a suction tube 8 provided at the bottom of the metering tube 7, an outlet 4 connected to the side of the metering tube 7, and the end of the outlet 4 away from the metering tube 7 being connected to the outside of the storage bottle 5 via the locking cap 1;

[0028] The metering tube 7 includes a tube body 71, with a single-pass tube 72 integrally provided at the bottom end of the tube body 71. A ball plug 73 is provided inside the single-pass tube 72, and a second spring 74 is attached to the ball plug 73. The top of the second spring 74 is attached to the bottom of the tube body 71. The liquid outlet 4 is connected to the side of the single-pass tube 72, and the suction tube 8 is connected to the single-pass tube 72 directly below the ball plug 73. A liquid passage hole 75 is provided in the middle of the bottom end of the tube body 71.

[0029] The outlet 4 includes a pressure pipe 41, with a nozzle 42 at the end of the pressure pipe 41. A baffle 43 is provided inside the nozzle 42, and an outlet groove 48 is opened in the middle of the baffle 43. A sealing plug 44 is connected inside the outlet groove 48. A connecting rod 45 is provided at one end of the sealing plug 44 inside the nozzle 42. The connecting rod 45 passes through the baffle 43 and is provided with a slide 46 to slide inside the nozzle 42. A first spring 47 is sleeved on the connecting rod 45 between the nozzle 42 and the baffle 43. The sealing plug 44 in the outlet 4 is used to seal it, so that the outlet 4 is always in a sealed state when the device is not in use, isolating the disinfectant in the outlet 4 from the outside world and preventing external dust and other objects from falling into the outlet 4.

[0030] Among them, the sealing plug 44 is made of rubber, which gives the sealing plug 44 a strong sealing effect. Then, the first spring 47 gives the sealing plug 44 a force to stick to the liquid outlet 48, so that the sealing plug 44 immediately blocks the outlet after the disinfectant is squeezed out.

[0031] The inner wall of the liquid outlet 48 is funnel-shaped, and the shape of the side of the sealing plug 44 is adapted to the inner wall of the liquid outlet 48. After the disinfectant is squeezed out, the funnel-shaped liquid outlet 48 will give the sealing plug 44 a rebound guiding ability, so that the sealing plug 44 can directly and completely seal the liquid outlet 48 after being pulled by the first spring 47, avoiding gaps.

[0032] The sealing plug 44 has multiple sets of spray holes 49 evenly distributed on its surface near the outer edge. The spray holes 49 allow the squeezed disinfectant to be sprayed outward through the outlet, so that the disinfectant can be used directly by spraying.

[0033] The outer edge of the tube body 71 is fitted with a mounting ring 76, which is set on the lock cover 1. The bottom end of the compression spring 6 is attached to the mounting ring 76. By setting the mounting ring 76, the compression spring 6 fitted on the tube body 71 has a fixed base. At the same time, the tube body 71 can be directly installed in the lock cover 1 using the mounting ring 76.

[0034] The pressure handle 2 includes a square rod 21. The bottom end of the square rod 21 passes through the metering tube 7 and a piston 25 is installed inside it. A baffle 22 is installed on the top of the square rod 21, and a support rod 23 is installed on the baffle 22. A pressure cap 24 is installed on the top of the support rod 23. The side of the support rod 23 is cut into a flat surface and a scale is set on the flat surface. The hole at the top of the metering tube 7 is adapted to the shape of the square rod 21. When the adjusting handle 3 rotates, the shape of the square rod 21 can be used to limit the pressure handle 2, preventing the pressure handle 2 from rotating with the adjusting handle 3. At the same time, the scale is set so that the adjusting handle 3 can be used as a reference to determine the pressing position of the pressure handle 2 during the height adjustment process, thereby achieving a precise metering effect.

[0035] The adjusting handle 3 includes a pressure ring 31, with a groove 32 in the middle of the pressure ring 31. The groove 32 is rotatably fitted onto the pressure handle 2. A bracket 33 is provided on the pressure ring 31, and an inner threaded sleeve 34 is provided on the top of the bracket 33. The inner threaded sleeve 34 is threaded onto the pressure handle 2. By rotating the inner threaded sleeve 34, the position of the adjusting handle 3 on the pressure handle 2 is adjusted, so that the pressure ring 31 presses against the pressure spring 6. When the pressure handle 2 is pressed, after being pressed to a certain extent, the pressure ring 31 will overlap with the metering tube 7, controlling the pressure handle 2 at a certain height, so that only a portion of the disinfectant can be squeezed out from the pressure handle 2.

[0036] Working principle: When using disinfectant, first adjust the position of the adjusting handle 3 so that the pressure handle 2 can only be pressed down to a certain height, precisely controlling the amount of disinfectant squeezed out. After pressing down the pressure handle 2, the adjusting handle 3 presses the pressure spring 6 and the metering tube 7 together as the pressure handle 2 is pressed down. At this time, the disinfectant in the metering tube 7 will be squeezed out through the outlet 4. Then, release the pressure handle 2, and the pressure spring 6 will give the adjusting handle 3 an upward push force, so that the adjusting handle 3 drives the pressure handle 2 to rise under the push force of the pressure spring 6, thereby creating a negative pressure in the metering tube 7. The disinfectant in the storage bottle 5 is sucked into the metering tube 7 by the suction tube 8, achieving a squeeze disinfectant cycle.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
