Description

Technical Field

[0001] This utility model relates to the field of spray pump technology, specifically an antibacterial and antistatic spray pump. Background Technology

[0002] Spray pumps are widely used in the packaging of pharmaceuticals, cosmetics, and cleaning agents. Their main function is to spray the internal liquid in a mist form by pressing. However, traditional spray pumps have two main problems during use: First, the pump body is in long-term contact with the liquid, which can easily breed bacteria, especially in high-temperature or humid environments. Bacterial growth can contaminate the liquid, affecting product quality and safety. Second, in dry environments, friction between the pump body and the liquid and air can easily generate static electricity, which may ignite sparks and pose a safety hazard, especially when in contact with flammable or explosive liquids.

[0003] In existing technologies, some spray pumps achieve antibacterial function by using antibacterial materials to make components, but the antibacterial effect is limited and the antistatic problem is not considered; other antistatic spray pumps eliminate static electricity by setting conductive components, but ignore the antibacterial requirements.

[0004] Therefore, a spray pump with both good antibacterial and antistatic properties is needed to meet the requirements of high hygiene and safety in application scenarios. Utility Model Content

[0005] The purpose of this invention is to provide an antibacterial and antistatic spray pump to solve the problems of insufficient antibacterial effect and easy static electricity generation in existing spray pumps, thereby improving the safety and hygiene of the spray pump.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An antibacterial and antistatic spray pump includes a pump body, a pressing head disposed on the top of the pump body, a suction pipe connected to the bottom of the pump body, and a piston disposed inside the pump body. The inner wall of the pump body is covered with an antibacterial coating, which is a nano-coating containing silver ions. Silver ions have a highly efficient antibacterial effect and can effectively inhibit the growth of bacteria inside the pump body.

[0007] Furthermore, a conductive fiber mesh is embedded inside the pump body's outer casing. The conductive fiber mesh is connected to a grounding terminal via a wire, and the grounding terminal extends to the outside of the pump body. The conductive fiber mesh can conduct static electricity generated by the pump body through the grounding terminal, preventing static electricity accumulation.

[0008] Furthermore, a composite antibacterial component is detachably connected to the nozzle of the press head. The composite antibacterial component includes an inner bamboo charcoal fiber layer and an outer antibacterial silicone layer. The bamboo charcoal fiber has adsorption and antibacterial properties, while the antibacterial silicone layer further enhances the antibacterial effect. The detachable design makes it easy to replace and ensures long-term antibacterial performance.

[0009] Furthermore, the outer surface of the piston is covered with an antibacterial coating, and a conductive rubber ring is provided at the edge where the piston contacts the inner wall of the pump body. The conductive rubber ring is in contact with the conductive fiber mesh. This design allows the static electricity generated by the piston during movement to be transferred to the conductive fiber mesh through the conductive rubber ring and then discharged through the grounding terminal, while preventing bacteria from growing on the piston surface.

[0010] Furthermore, the composite antibacterial nozzle is connected to the nozzle via a threaded structure, making it easy to disassemble and replace. The center of the composite antibacterial nozzle has a spray hole that communicates with the nozzle, and the inner wall of the spray hole is also covered with an antibacterial coating to ensure that the sprayed liquid remains clean in the final stage.

[0011] Furthermore, the suction tube is made of polyethylene with added antibacterial agents, which further enhances the antibacterial effect during the liquid absorption process. The outer wall of the suction tube is wrapped with conductive wires, one end of which is connected to a conductive fiber mesh, and the other end extends to the end of the suction tube, preventing the suction tube from generating static electricity due to friction in the liquid.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This utility model, through the design of an antibacterial and antistatic spray pump, achieves the following effects: 1. The inner wall of the pump body and the outer surface of the piston are covered with a nano-antibacterial coating containing silver ions. The composite antibacterial nozzle adopts a double-layer structure of bamboo charcoal fiber layer and antibacterial silicone layer. The suction tube is made of polyethylene material with added antibacterial agent, forming a full-path antibacterial protection from suction to spray, effectively inhibiting bacterial growth and solving the problem of easy contamination of various components of traditional spray pumps. It is especially suitable for fields with high hygiene requirements such as medicine and cosmetics; 2. The replaceable composite antibacterial nozzle is connected to the nozzle through a threaded structure, which is convenient for regular replacement to maintain the antibacterial effect and solves the problem of traditional nozzles being easy to adhere to microorganisms and difficult to clean. The inner wall of the spray hole is also covered with an antibacterial coating to ensure that the final stage before the liquid is sprayed remains clean; 3. The conductive fiber mesh embedded in the pump body shell contacts the conductive rubber ring on the edge of the piston, and the conductive wire wrapped around the outer wall of the suction tube is connected to... The conductive fiber mesh, combined with the grounding terminal extending to the outside of the pump body, forms a complete electrostatic conduction path from the piston and suction tube to the pump body, effectively dissipating static electricity generated by friction and solving the safety hazards of static electricity accumulation in traditional spray pumps; 4. The pump body is made of polypropylene, and the embedded depth of the conductive fiber mesh is controlled at 0.5-1mm, ensuring both structural strength and electrostatic conduction efficiency; the antibacterial coating thickness is 0.01-0.03mm and the silver ion mass fraction is 0.5%-1%, ensuring antibacterial effect while avoiding material waste, solving the problem of balancing performance and cost in single-function designs; 5. The antibacterial structure and antistatic path are independent yet synergistic, blocking the bacterial reproduction chain through multi-layer antibacterial design and dissipating static electricity through a complete conductive network, meeting the dual high requirements of hygiene and safety in the pharmaceutical, cosmetic and other fields, and solving the problems of single function and limited application range of traditional spray pumps.

The composite antibacterial nozzle 8 is also provided with a spray hole 803 communicating with the nozzle 7. The composite antibacterial nozzle 8 is connected to the nozzle 7 by a threaded structure. The spray hole 803 is located at the center of the composite antibacterial nozzle 8, and the inner wall of the spray hole 803 is also covered with an antibacterial coating 4.

[0020] Example 4 Please see Figure 2Based on Example 1, this embodiment further specifies that the outer surface of the piston 9 is covered with an antibacterial coating 4, and a conductive rubber ring 10 is provided at the edge where the piston 9 contacts the inner wall of the pump body 1.

[0021] Example 5 Please see Figure 1 and Figure 2 Based on Example 1, the pump body 1 is made of polypropylene, the conductive fiber mesh 5 is embedded to a depth of 0.5-1mm in the outer shell of the pump body 1, and the conductive rubber ring 10 is in contact with the conductive fiber mesh 5 to form an electrostatic conduction path.

[0022] Example 6 Please see Figure 4 Based on Example 1, the material of the suction tube 3 is polyethylene with added antibacterial agent. The outer wall of the suction tube 3 is wrapped with conductive wire 12. One end of the conductive wire 12 is connected to the conductive fiber mesh 5, and the other end extends to the end of the suction tube 3.

[0023] The working process of this utility model is as follows: When using this antibacterial and antistatic spray pump, first press the press head 2, which drives the piston 9 inside the pump body 1 to move upward, creating a negative pressure inside the pump body 1.

At the same time, the conductive rubber ring 10 on the edge of the piston 9 contacts the conductive fiber mesh 5, conducting the static electricity generated by the movement of the piston 9 to the conductive fiber mesh 5. When the press head 2 is released, the piston 9 moves downward under the action of the reset mechanism, and the liquid inside the pump body 1 is pressurized and flows to the nozzle 7. The conductive fiber mesh 5 inside the outer shell 11 conducts the accumulated static electricity to the grounding terminal 6 through the wire, and then leads it out of the pump body 1 through the grounding terminal 6. The liquid enters the composite antibacterial nozzle 8 through the nozzle 7.

Finally, it is sprayed out through the spray hole 803. The antibacterial coating 4 on the inner wall of the spray hole 803 ensures that the liquid remains clean in the final stage before it is sprayed out.
