Description

Technical Field

[0001] This utility model relates to the field of spray device technology, specifically an environmentally friendly press-type spray head. Background Technology

[0002] In existing environmentally friendly push-button spray head technology, most traditional push-button spray heads have a fixed liquid output, which cannot be flexibly adjusted according to actual usage needs. However, in practical applications, different usage scenarios (such as cleaning items with different levels of stains, spraying liquids of different concentrations, etc.) have different requirements for the liquid output. The few existing spray heads with adjustable liquid output often have complex adjustment structures, are inconvenient to operate, and make it difficult for users to accurately control the liquid output, resulting in unscientific liquid use and waste. Traditional push-button spray heads mostly use non-degradable plastic materials, such as polyethylene and polypropylene. These materials are difficult to degrade in the natural environment and will persist for a long time after being discarded, forming white pollution and causing serious harm to the ecological environment. With the increasing awareness of environmental protection, the demand for biodegradable and environmentally friendly materials is becoming increasingly urgent, but existing spray heads have made little improvement in this regard.

[0003] Therefore, it is necessary to design an environmentally friendly press-type nozzle to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this utility model is to provide an environmentally friendly press-type spray head, which aims to solve the problems existing in press-type spray heads in terms of liquid output adjustment, material environmental friendliness, and structural durability. Through innovative structural design and the application of environmentally friendly materials, it achieves precise control of liquid spraying, reduces waste and pollution, extends the service life of the spray head, and promotes the development of spray devices towards a green and efficient direction.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An environmentally friendly press-type nozzle mainly consists of a nozzle body, a press-type component, and a liquid dispensing adjustment component.

[0006] Furthermore, the nozzle body is used to connect to the container and contain the liquid. It has a threaded connection seat at the bottom for easy and secure connection with the bottle mouth. The bottom of the threaded connection seat has an outer tube, and the bottom of the outer tube is connected to a connecting pipe for liquid introduction. The nozzle body has a nozzle at the front end for liquid spraying. In particular, the nozzle body is made of polylactic acid biodegradable material and has a liquid storage chamber inside. While ensuring structural strength, it meets environmental protection requirements and reduces white pollution.

[0007] Furthermore, the pressing assembly is located on the nozzle body and includes a pressing switch, a liquid guide tube, a return spring, and a piston rod. The return spring is sleeved on the outside of the piston rod. When the pressing switch is pressed, the piston rod moves downward, connecting the liquid storage chamber with the liquid guide tube. Under pressure, the liquid is sprayed out of the nozzle through the liquid guide tube. After the pressing switch is released, the return spring resets the piston rod, closing the liquid passage.

[0008] Furthermore, the liquid discharge adjustment component is located inside the nozzle body and includes an adjustment knob, a drive rod, a flow restrictor, and a liquid discharge hole. The flow restrictor has multiple liquid discharge holes with different diameters. The bottom of the adjustment knob is connected to the flow restrictor. By rotating the adjustment knob, the drive rod can be driven to rotate the flow restrictor, so that the liquid discharge holes with different diameters are aligned with the liquid guiding channel inside the liquid guiding tube, thereby realizing the adjustment of the liquid discharge volume.

[0009] Furthermore, a limiting block is provided on the outer periphery of the side of the flow restrictor away from the drive rod. The limiting block is inserted into the slot of the outer mesh of the liquid guide tube, so that the flow restrictor is completely inserted into the liquid guide tube, ensuring the stability of the adjustment.

[0010] Furthermore, sealing gaskets are provided around the top and bottom of multiple liquid outlets to form a seal when the flow restrictor is inserted into the liquid guide tube, thus preventing leakage.

[0011] Furthermore, the flow restrictor is made of food-grade PP material, which is safe and reliable, ensuring the hygiene of the liquid.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This utility model, through the design of an environmentally friendly press-type nozzle, achieves the following effects: 1. The liquid dispensing adjustment component is equipped with an adjustment knob, a flow restrictor, and multiple dispensing holes of different diameters. Users can easily adjust the dispensing volume by simply rotating the adjustment knob, causing the flow restrictor to rotate and aligning the dispensing holes of different diameters with the liquid guiding channel. This satisfies the diverse needs for dispensing volume in different usage scenarios, avoids excessive liquid use, and achieves the goal of environmental protection and conservation; 2. The nozzle body is made of polylactic acid (PLA), a biodegradable polymer material that can be decomposed by microorganisms in the natural environment, reducing the white pollution problem caused by traditional non-degradable plastics. This aligns with current environmental development trends and promotes the product's development towards a green and sustainable direction. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] To facilitate understanding of this utility model, a more comprehensive description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are provided. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0017] Example 1 Please see Figure 1 This embodiment provides an environmentally friendly press-type nozzle, including a nozzle body 1, a press-type component 2, and a liquid discharge adjustment component 3; The nozzle body 1 is used to connect to the container and contain the liquid. It has a threaded connection seat 4 at its bottom, an outer sleeve 5 at the bottom of the threaded connection seat 4, and a connecting pipe 6 at the bottom of the outer sleeve 5. The nozzle body 1 has a nozzle 7 at its front end. The pressing component 2 is set on the nozzle body 1 to realize the function of pressing to dispense liquid. The liquid dispensing adjustment component 3 is set inside the nozzle body 1 to adjust the liquid dispensing volume. The three components work together to complete the process of liquid extraction, adjustment and spraying.

[0018] Example 2 Please see Figure 1 Based on Example 1, this example provides a detailed description of the material and structure of the nozzle body 1. The nozzle body 1 is made of polylactic acid (PLA) biodegradable material, which can be decomposed by microorganisms in the natural environment, effectively reducing white pollution and meeting environmental protection requirements. The nozzle body 1 has a liquid storage chamber inside for temporarily storing the liquid to be sprayed. Its bottom is connected to the top of the threaded connector 4, which can securely connect it to the container, ensuring the stability of the liquid delivery process.

[0019] Example 3 Please see Figure 2Based on Embodiment 1, this embodiment describes in detail the structure and working principle of the pressing assembly 2. The pressing assembly 2 includes a pressing switch 21, a liquid guide tube 22, a reset spring 23, and a piston rod 24. The reset spring 23 is sleeved on the outside of the piston rod 24. When the pressing switch 21 is pressed, the piston rod 24 moves downward and compresses the reset spring 23, so that the piston rod 24 is connected to the liquid storage chamber and the liquid guide tube 22. Under pressure, the liquid in the liquid storage chamber is sequentially transported through the piston rod 24 and the liquid guide tube 22 to the nozzle 7 for spraying. After the pressing switch 21 is released, the reset spring 23 resets and drives the piston rod 24 to move upward, cutting off the liquid passage and stopping the liquid discharge.

[0020] Example 4 Please see Figure 3 Based on Example 1, this example describes the structure and adjustment method of the liquid outlet regulating component 3. The liquid outlet regulating component 3 includes an adjusting knob 31, a drive rod 32, a flow restrictor 33, and liquid outlet holes 34. The flow restrictor 33 is provided with multiple liquid outlet holes 34 of different diameters, and the bottom of the adjusting knob 31 is connected to the flow restrictor 33. When it is necessary to adjust the liquid outlet volume, rotating the adjusting knob 31 drives the flow restrictor 33 to rotate synchronously through the drive rod 32, so that the liquid outlet holes 34 of different diameters are aligned with the liquid guiding channel inside the liquid guiding tube 22. By utilizing the limiting effect of the liquid flow rate of the liquid outlet holes 34 of different diameters, the graded adjustment of the liquid outlet volume is achieved.

[0021] Example 5 Please see Figure 3 Based on Example 4, this example provides supplementary explanation of the installation and positioning structure of the flow restrictor 33. A limiting block 35 is provided on the outer periphery of the flow restrictor 33 on the side away from the drive rod 32, and a corresponding slot is provided on the outer mesh of the liquid guide tube 22. When installing the flow restrictor 33, the limiting block 35 is inserted into the slot, so that the flow restrictor 33 is completely inserted into the liquid guide tube 22, preventing the flow restrictor 33 from shifting or shaking during rotation adjustment, ensuring the accuracy of the alignment between the liquid outlet 34 and the liquid guide channel, and ensuring the stability of the liquid output adjustment.

[0022] Example 6 Please see Figure 3 Based on Example 4, this example describes the sealing structure between the flow restrictor 33 and the liquid guide tube 22. Sealing gaskets are provided around the top and bottom peripheries of the multiple liquid outlet holes 34. When the flow restrictor 33 is inserted into the liquid guide tube 22, the sealing gaskets tightly adhere to the contact surfaces of the flow restrictor 33 and the liquid guide tube 22, forming a sealed design. This structure effectively prevents liquid leakage at the connection between the liquid outlet hole 34 and the liquid guide channel, avoiding liquid waste and contamination, and improving the sealing performance and reliability of the nozzle.

[0023] Example 7 Please see Figure 3Based on Example 4, this example describes the material of the flow restrictor 33. The flow restrictor 33 is made of food-grade PP material, which has good chemical stability and safety and will not react chemically with liquids. It is especially suitable for liquid scenarios with high hygiene requirements, such as contact with food and cosmetics, to ensure the purity and safety of the liquid.

[0024] The working process of this utility model is as follows: When using this environmentally friendly press-button nozzle, firstly, connect the connecting pipe 6 to the container outlet, and fix the nozzle body 1 to the container through the threaded connector 4, ensuring that the outer sleeve 5 is sealed and connected to the connecting pipe 6, thus completing the liquid delivery path. The liquid in the container enters the liquid storage chamber of the nozzle body 1 through the connecting pipe 6 and the outer sleeve 5, where the liquid is temporarily stored and awaits spraying. Then, press the press switch 21, which moves the piston rod 24 down and compresses the return spring 23, connecting the piston rod 24 to the liquid storage chamber and the liquid guide pipe 22. The liquid is then sprayed out from the nozzle 7 through the piston rod 24, the liquid guide pipe 22, and the liquid outlet adjustment component 3 in sequence. Release the press switch 21, and the return spring 23 moves the piston rod 24 back to its original position, cutting off the flow. The liquid flow stops when the flow rate is adjusted. When the flow rate needs to be adjusted, rotate the adjustment knob 31, which drives the flow restrictor 33 to rotate via the drive rod 32. This aligns the outlet holes 34 of different diameters with the liquid channel of the guide tube 22, allowing the flow rate to be adjusted by utilizing the difference in diameter. The limiting block 35 engages with the slot of the guide tube 22, ensuring accurate positioning of the flow restrictor 33. When the flow restrictor 33 engages with the guide tube 22, the sealing gasket around the outlet hole 34 forms a seal to prevent liquid leakage and ensure that all liquid is delivered through the selected outlet hole 34. If cleaning or replacement of parts is required, loosen the threaded connector 4 to separate the nozzle from the container, and disassemble the pressing assembly 2 and the liquid flow adjustment assembly 3 for maintenance. When replacing the flow restrictor 33, food-grade PP material should be used first to ensure safe use.

[0025] 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.
