Description

Technical Field

[0001] This utility model relates to the field of aerospace engineering technology, specifically a novel hand sanitizer dispenser. Background Technology

[0002] Hand sanitizer on airplanes is an important feature to ensure passenger hygiene and health. It is usually placed in the lavatory, and the small bottle is easy to use. Its ingredients are gentle and can effectively clean dirt and bacteria from hands. During the flight, passengers can conveniently clean their hands in a limited space, adding a sense of security and comfort to the journey and reflecting the attention to detail in airline services.

[0003] Traditional hand sanitizer dispensers have significant drawbacks. They lack the ability to precisely control the amount of hand sanitizer dispensed, often resulting in users squeezing out too much at once and wasting it. In addition, their sealing performance is poor, making them prone to leakage. On airplanes, due to airflow vibrations and the impact of landing, ordinary hand sanitizer dispensers may be damaged and rendered unusable. Utility Model Content

[0004] The purpose of this invention is to provide a novel hand sanitizer dispenser to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel hand sanitizer dispenser, comprising:

[0006] Dispensing nozzle, top cap, and connecting rod;

[0007] The liquid outlet is disposed on the upper cover, the upper cover is snapped onto the connecting rod, the liquid outlet is provided with a liquid outlet push rod, the liquid outlet push rod moves in the liquid outlet, and the liquid outlet push rod is provided with a push rod spring;

[0008] The upper cover is equipped with a pressing head and a liquid dispensing rod, and a pressing spring is provided on the outer side of the liquid dispensing rod.

[0009] Preferably, the outlet nozzle is further provided with an outlet valve, which is pushed and moved by the outlet push rod.

[0010] Preferably, the dispensing rod is movably provided with a ball bearing and a sealing ring that is snapped onto the outside of the dispensing rod, the sealing ring enhancing the sealing performance between the dispensing rod and the pressing head.

[0013] Preferably, the bottom of the liquid outlet rod is provided with a connecting seat for supporting the pressing spring.

[0014] Preferably, the dispensing nozzle is threaded for connection with the upper cover and the pressing head.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This new hand sanitizer dispenser features a nozzle valve design that allows for better control of the amount of hand sanitizer dispensed, ensuring even distribution throughout the pressing stroke. Unlike traditional hand sanitizer dispensers, it does not dispense excessive amounts of hand sanitizer at once.

[0017] This new hand sanitizer dispenser is designed to withstand the vibrations that airplanes experience when encountering airflow at high altitudes and the impact force upon landing. The design incorporates a nested structure of the top cover, pump head, and connecting rod to enhance structural strength and ensure stability during the vertical movement, resulting in a secure and stable installation.

[0018] This new hand sanitizer dispenser is designed with a push rod spring to minimize the risk of insufficient external air pressure causing the dispensing valve to retract and close the dispensing port in time, thus ensuring that hand sanitizer is drawn into the dispensing chamber to the maximum extent. This is because air pressure and ambient temperature often change during aircraft flight.

[0019] This new hand sanitizer dispenser features a single ball bearing design, which, compared to the traditional double ball bearing design, better controls the liquid seal of the cavity, reduces air residue, and ensures a smooth flow of hand sanitizer for the user.

[0024] 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.

[0025] Please see Figure 1-2 This utility model provides a technical solution: a novel hand sanitizer pump device, comprising: a dispensing nozzle 1, a top cover 4, and a connecting rod 9. One end of the dispensing nozzle 1 is threaded for threaded connection with the top cover 4 and the pump head 5. During flight, the threaded connection will not come loose due to aircraft vibration. The top cover 4 is snapped onto the pump head 5 to expand the pressing range and facilitate operation of the entire device, while also limiting and fixing the pump head 5 and the connecting rod 9. The connecting rod 9 serves as the base of the pumping mechanism and is used to connect to the hand sanitizer bottle. The dispensing nozzle 1 is located on the top cover 4 and primarily passes through the top cover 4 and connects to the sealing ring 6 of the pump head 5, ensuring communication between the dispensing rod 8 and the hollow connecting tube of the pump head 5. The top cover 4 is snapped onto the connecting rod 9, primarily to secure the connection between the pump head 5 and the dispensing rod 8. Both the top cover 4 and the connecting rod 9 function as the outer shell of the device, and the connecting rod 9 contains a mounting plate for installation. The mounting plate is used to fix the dispensing rod 8, preventing it from moving within the connecting rod 9 and falling off. This connection method effectively ensures the stability of the device connection during turbulence in flight. The dispensing nozzle 1 is equipped with a dispensing push rod 3. When the pressing head 5 is pressed down, the pressure inside the hollow tube of the pressing head 5 increases, and the ball bearing 7 presses against the dispensing rod 8. Air and absorbent liquid drive the dispensing nozzle valve 2 to push out the dispensing push rod 3, thereby expelling gas or hand sanitizer. The dispensing push rod 3 moves within the dispensing nozzle 1. The dispensing push rod 3 is equipped with a push rod spring 10, which is used to reset the dispensing push rod 3, ensuring that the dispensing push rod 3 can automatically reset when not in use. The upper cover 4 is equipped with a pressing head 5 and a dispensing rod 8. The dispensing rod 8 is pressed down by the pressing head 5 and moves downward. A pressing spring 11 is provided on the outer side of the dispensing rod 8, which is used to reset the dispensing rod 8 upward, facilitating a second press.

[0026] When the press head 5 is pressed, the pressure inside its hollow tube increases, the ball bearing 7 presses against the dispensing rod 8, and the air and hand sanitizer work together to push the dispensing nozzle valve 2 to push out the dispensing top rod 3, thereby expelling gas or hand sanitizer. After releasing, the top rod spring 10 drives the dispensing top rod 3 to return to its original position, and the pressing spring 11 pushes the dispensing rod 8 upward to return to its original position for the next pressing operation. During aircraft flight, whether due to airflow vibration or landing impact, the threaded connection, snap-fit, and the ingenious design of each component can effectively maintain the stability of the device connection, ensuring its normal operation, precisely controlling the dispensing and resetting of hand sanitizer, and avoiding problems such as component detachment or damage due to the special environment of the aircraft, thus providing reliable protection for the use of hand sanitizer on airplanes.

[0027] The dispensing nozzle 1 is also equipped with a dispensing nozzle valve 2, which is embedded in the dispensing nozzle 1 and the outlet is designed to be open. This design can ensure that the hand sanitizer will not drip down during use. The dispensing nozzle valve 2 is pushed and moved by the dispensing push rod 3 and pushed out and reset by the push rod spring 10. The dispensing nozzle 1 is provided with threads for connecting with the top cover 4 and the press head 5.

[0028] The dispensing nozzle 1 contains an embedded dispensing valve 2 with a tapered outlet to prevent hand sanitizer dripping. The dispensing valve 2 is displaced by the dispensing push rod 3 and reset by the push rod spring 10. The threads on the dispensing nozzle 1 are used to connect with the top cover 4 and the press head 5, ensuring a tight connection between all components. During flight, this connection method can withstand airflow vibrations and landing impacts, ensuring the normal operation and stability of the device, and ensuring that the dispensing valve 2 and related components work according to the process, achieving accurate dispensing and reset, and maintaining the effective operation of the device in the aircraft environment.

[0029] The press head 5 is snapped onto the connecting rod 9. The press head 5 is hollow and connected to the dispensing rod 8 to ensure that the hand sanitizer can be pushed upward by downward pressure. The hollow space between the press head 5 and the connecting rod 9 serves as a flow channel for the hand sanitizer, ensuring that the hand sanitizer can be pulled upward. The pressing spring 11 is located on the outside of the press head 5 and the connecting rod 9. The bottom of the dispensing rod 8 is provided with a connecting seat, which is used to support the pressing spring 11.

[0030] When the press head 5 is released, the press spring 11 rebounds and lifts the press head 5. The hollow tube space collides, the pressure decreases, and the resulting air or hydraulic pressure cannot lift the dispensing valve 2. The push rod spring 10 rebounds, and the dispensing valve 2 seals the dispensing hole. The hollow drain tube, with its reduced pressure, is lifted by the hand sanitizer below, and the hand sanitizer is drawn out of the drain tube. When the press head 5 rebounds and settles, because the mass of the ball 7 is greater than that of the hand sanitizer, it will press against the hollow drain tube of the dispensing rod 8 under the influence of gravity, thus preventing the hand sanitizer from flowing back into the storage tank. The next time you press it, the hand sanitizer can be dispensed.

[0031] When the new hand sanitizer pump is in use, the pump head 5 is snapped into the connecting rod 9 and is hollow, communicating with the dispensing rod 8 to form a hand sanitizer flow channel. When pressed, the pressure in the hollow tube inside the pump head 5 increases due to the downward pressure. The ball bearing 7 presses against the dispensing rod 8. The combined action of air and hand sanitizer causes the dispensing valve 2 embedded in the dispensing nozzle 1 to push out the dispensing push rod 3, thus discharging gas or hand sanitizer. After releasing the pump head 5, the pressing spring 11 rebounds and pushes the pump head 5 back up. The pressure in the hollow tube space decreases, and the insufficient air or hydraulic pressure pushes up the dispensing valve 2. The push rod spring 10 resets the valve and seals the dispensing hole. At the same time, the ball bearing 7, due to its greater weight than the hand sanitizer, presses against the hollow unblocking tube of the dispensing rod 8 to prevent hand sanitizer from flowing back into the storage tank, so that the hand sanitizer can be smoothly squeezed out the next time it is pressed. During the flight of the aircraft, the various components are tightly connected by means of threaded connection, snap-fit, etc., which effectively copes with airflow vibration and landing impact, ensuring stable operation of the device and accurate dispensing and resetting.

[0032] 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.
