Description

Technical Field

[0001] This utility model relates to the field of pump head technology and belongs to a high-temperature resistant pump head. Background Technology

[0002] In daily life, many products use bottles with pump heads, such as shower gel, shampoo, hand soap, and even oil containers used in the kitchen. The pump head facilitates the extraction of liquids through pumping, making it convenient to use. A typical pump head has a plastic body with the outlet located on it. When the pump head is pressed down, the outlet moves, and liquid flows out. Releasing the pump head causes a spring inside to return to its original position, pushing a piston upward to close the drain hole and simultaneously opening another valve, allowing new liquid to enter the pump head. Repeating this pressing process allows for repeated dispensing of liquid.

[0003] To prevent liquid leakage, existing pump heads have a sealing structure. For example, the pump head with prior art publication number CN216660976U includes an outer cover, a pressure head fixedly connected to the inner side of the outer cover, a nozzle connected to the inner side of the right end of the pressure head, and a sealing mechanism for protecting the nozzle.

[0004] However, the above-mentioned existing technology still has the following problems when used: the pump head is used in different environments. When the pump head is used in a high-temperature environment, since the existing pump heads are usually made of ordinary plastic, the liquid outlet nozzle of the pump head will soften after being heated at high temperature for a long time. The softened liquid outlet nozzle will cause blockage of the liquid outlet, which will affect the flow of liquid. Based on this, the present invention provides a high-temperature resistant pump head. Utility Model Content

[0005] Therefore, this utility model provides a high-temperature resistant pump head to solve the problem in the prior art where the pump head softens due to long-term high-temperature heating, leading to blockage of the liquid outlet and affecting the flow of liquid.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-temperature resistant pump head includes a pump head body and a liquid outlet nozzle. The liquid outlet nozzle is fixed to the front end of the pump head body and communicates with the pump head body. A high-temperature resistant protective assembly is sleeved on the outside of the liquid outlet nozzle. The high-temperature resistant protective assembly includes a protective shell sleeved on the outside of the liquid outlet nozzle. An opening is provided at the front end of the protective shell. An arc-shaped baffle is hinged in the opening. The arc-shaped baffle is connected to the protective shell by a snap-fit ​​assembly. Multiple fluororubber sheets are fixedly provided on the inner wall of the protective shell and the inner wall of the arc-shaped baffle. The multiple fluororubber sheets are in contact with the outer wall of the pump head body.

[0008] Furthermore, both the protective shell and the arc-shaped baffle are made of polyetheretherketone (PEEK) plastic, which is a high-performance thermoplastic engineering plastic with high temperature resistance. Therefore, it can improve the high temperature resistance of the protective shell and the arc-shaped baffle, and thus play a role in blocking high temperature on the outside of the liquid outlet nozzle.

[0009] Furthermore, multiple mounting slots are provided on the inner walls of both sides of the front end of the opening, and multiple mounting slots are provided on both sides of the rear end of the arc-shaped baffle, for storing the snap-fit ​​components.

[0010] Furthermore, the snap-fit ​​assembly includes multiple female snap heads and multiple male snap heads. The multiple female snap heads are respectively fixed in multiple mounting slots one and multiple male snap heads are respectively fixed in multiple mounting slots two. The male snap heads and female snap heads are snapped together. By using multiple male snap heads and multiple female snap heads to snap together, the connection between the arc-shaped baffle and the protective shell can be greatly improved, and the loosening of the arc-shaped baffle can be avoided from affecting the protection of the liquid nozzle.

[0011] Furthermore, the top of the rear end of the arc-shaped baffle has two slots, and each slot has a round rod. Both ends of the round rod are fixed to the inner wall of the front end of the opening through connecting plates. Each round rod is fitted with a torsion spring, which is connected to the inner wall of the slot and the inner wall of the front end of the opening, respectively. When the arc-shaped baffle is opened, the two torsion springs lose pressure and generate a reaction force, thereby pushing the arc-shaped baffle to automatically flip open.

[0012] Furthermore, a silicone rubber pad is fixedly provided on the top of the protective shell. The silicone rubber pad is located behind the arc-shaped baffle. The silicone rubber pad is made of soft material. When the user presses the protective shell, the fingers come into contact with the silicone rubber pad, which can improve the comfort of the fingers contacting the protective shell.

[0013] Furthermore, the protective shell and the liquid outlet nozzle are detachably fixed together by multiple bolts. Specifically, the protective shell and the liquid outlet nozzle are connected by bolts, and the protective shell can be removed from the liquid outlet nozzle by loosening the bolts, which can facilitate cleaning and replacement, as well as recycling.

[0014] Furthermore, the outer walls of the protective shell and the arc-shaped baffle are coated with heat-insulating paint. The heat-insulating paint can effectively prevent heat transfer, thus further improving the high-temperature resistance of the protective shell and the arc-shaped baffle, thereby improving the protection of the liquid outlet nozzle.

[0015] This utility model has the following advantages:

[0016] 1. This utility model uses a protective shell and an arc-shaped baffle on the outside of the liquid outlet nozzle. Both the protective shell and the arc-shaped baffle are made of polyetheretherketone plastic, which has high temperature resistance. Therefore, they can not only block high temperature on the outside of the liquid outlet nozzle, but also protect the liquid outlet nozzle, thereby extending the service life of the liquid outlet nozzle.

[0017] 2. The arc-shaped baffle and the protective shell are connected by a torsion spring. The torsion spring can drive the arc-shaped baffle to open automatically. At the same time, the connection between the arc-shaped baffle and the protective shell is improved by using multiple male and female snap buttons. Attached Figure Description

[0029] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] Refer to the instruction manual appendix Figure 1-6 This utility model provides a high-temperature resistant pump head, including a pump head body 1 and a liquid outlet nozzle 2. The liquid outlet nozzle 2 is fixed to the front end of the pump head body 1 and is connected to the pump head body 1. A high-temperature resistant protective component 3 is sleeved on the outside of the liquid outlet nozzle 2. The high-temperature resistant protective component 3 includes a protective shell 301 sleeved on the outside of the liquid outlet nozzle 2. An opening 302 is opened at the front end of the protective shell 301. An arc-shaped baffle 303 is hinged in the opening 302. The arc-shaped baffle 303 is connected to the protective shell 301 by a snap-fit ​​component 4. Multiple fluororubber sheets 5 are fixedly provided on the inner wall of the protective shell 301 and the inner wall of the arc-shaped baffle 303. The multiple fluororubber sheets 5 are in contact with the outer wall of the pump head body 1. The fluororubber sheets 5 have excellent high-temperature resistance, so they can block high temperatures between the protective shell 301, the arc-shaped baffle 303 and the pump head body 1.

[0031] To improve the high-temperature resistance of the protective shell 301 and the arc-shaped baffle 303, both the protective shell 301 and the arc-shaped baffle 303 are made of polyetheretherketone (PEEK) plastic. PEEK plastic is a high-performance thermoplastic engineering plastic with high-temperature resistance, thus enabling the protective shell 301 and the arc-shaped baffle 303 to have high-temperature resistance.

[0032] The outer walls of the protective shell 301 and the arc-shaped baffle 303 are coated with heat-insulating paint. The heat-insulating paint is a functional paint that can effectively prevent heat transfer, which can further improve the high temperature resistance of the protective shell 301 and the arc-shaped baffle 303, thereby improving the protection of the liquid outlet nozzle 2.

[0033] Furthermore, two grooves 8 are provided at the top rear end of the arc-shaped baffle 303. A round rod 9 is provided in each groove 8. Both ends of the round rod 9 are fixed to the inner wall of the front end of the opening 302 through the connecting plate 10. A torsion spring 11 is sleeved on each of the two round rods 9. The torsion spring 11 is connected to the inner wall of the groove 8 and the inner wall of the front end of the opening 302, respectively. Specifically, the torsion spring 11 is an elastic element that can withstand torsional deformation. Its basic structure is mainly made of spring wire. The cross-section of the spring wire is usually circular or rectangular and generally spiral. When one end is fixed and torque is applied to the other end, the spring will produce elastic deformation and store elastic potential energy. Therefore, the arc-shaped baffle 303 and the opening 302 are connected by the torsion spring 11. When the arc-shaped baffle 303 is opened, the elastic potential energy stored in the two torsion springs 11 is released, which can push the arc-shaped baffle 303 to automatically flip open.

[0034] A silicone rubber pad 12 is fixedly provided on the top of the protective shell 301. The silicone rubber pad 12 is located behind the arc-shaped baffle 303. The silicone rubber pad 12 has excellent high temperature resistance, so it can be used in high temperature environments. At the same time, the silicone rubber pad 12 is made of soft material, and the silicone rubber pad 12 can improve the comfort of fingers contacting the protective shell 301.

[0035] The protective shell 301 is detachably fixed to the liquid outlet nozzle 2 by multiple bolts. After long-term use, the bolts can be loosened to remove the protective shell 301 from the liquid outlet nozzle 2, which can be convenient for cleaning and replacement, and can also be recycled and reused.

[0036] Install the pump head body 1 onto the bottle neck. When liquid needs to be dispensed, the user first opens the arc-shaped baffle 303. At this time, the two torsion springs 11 between the arc-shaped baffle 303 and the opening 302 lose pressure, so the torsion springs 11 generate elastic force to push the arc-shaped baffle 303 to flip open. Then, press down on the protective shell 301 with your finger to drive the liquid nozzle 2 to press down on the pump head body 1, and the liquid can be dispensed. After use, release the protective shell 301, and then push the arc-shaped baffle 303 back into the opening 302. Use the snap-fit ​​component 4 to keep the arc-shaped baffle closed. Plate 303 is firmly fixed inside opening 302. Since both protective shell 301 and arc-shaped baffle 303 are made of polyetheretherketone plastic, they can block high temperature on the outside of liquid outlet nozzle 2 and protect the outside of liquid outlet nozzle 2. This can improve the high temperature resistance of liquid outlet nozzle 2 and extend its service life. In addition, multiple fluororubber sheets 5 are provided on the inner wall of protective shell 301 and arc-shaped baffle 303. The multiple fluororubber sheets 5 are in contact with the outer wall of pump head body 1, which can reduce the flow of high temperature air.

[0037] Refer to the instruction manual appendix Figure 1-6 The snap-fit ​​assembly 4 includes multiple female snap heads 401 and multiple male snap heads 402, with the male snap heads 402 snapped together with the female snap heads 401.

[0038] Specifically, the female snap head 401 is usually a component with a hollow or recessed structure, and the male snap head 402 is a component corresponding to the female snap head 401. The shape of the male snap head 402 is generally convex, matching the recessed structure of the female snap head 401. By using multiple male snap heads 402 and multiple female snap heads 401 to fasten together, the connection between the arc-shaped baffle 303 and the protective shell 301 can be greatly improved, while also facilitating the separation of the arc-shaped baffle 303 and the protective shell 301.

[0039] Multiple mounting slots 6 are provided on the inner walls of both sides of the front end of the opening 302, and multiple mounting slots 7 are provided on both sides of the rear end of the arc-shaped baffle 303. Multiple female snap fasteners 401 are fixed in the multiple mounting slots 6, and multiple male snap fasteners 402 are fixed in the multiple mounting slots 7, for storing the male snap fasteners 402 and the female snap fasteners 401.

[0040] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
