Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of pump bodies, and particularly relates to a push head anti - detachment and sound - effect structure. Background Technique
[0002] Liquid or foam pumping devices are widely used in the fields of transportation and spraying of various liquids or foams, such as perfumes, cosmetics, cleaners, etc. These devices usually include components such as a pump head, a pump core, and a decorative cover. As an important part of the liquid pumping device, the connection reliability between the pump head and the pump core and the decorative cover directly affects the use performance and service life of the entire device.
[0003] In the prior art, the pump head is mainly fixed to the pump core and the decorative cover by means of threaded connection or snap - connection. However, these connection methods have the following problems:
[0004] 1. During use or transportation, the pump head may be subjected to a large impact force, resulting in the loosening or even detachment of its connection with the pump core and the decorative cover, affecting the normal use of the pumping device;
[0005] 2. The existing connection methods lack an effective feedback mechanism and cannot intuitively prompt the user of the connection status, and cannot give sufficient feedback when the pump head is successfully screwed in or out.
[0006] Therefore, it is necessary to provide a new type of push - head anti - detachment device that can effectively prevent the pump head from loosening when subjected to impact, and at the same time has a connection - status prompt function to improve the use reliability and safety of the pumping device. Content of the Utility Model
[0007] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a push - head anti - detachment and sound - effect structure, which is mainly used to solve the defects such as the easy loosening of the push - head structure and the lack of connection - status feedback in the prior art.
[0008] To solve the above problems, the technical solutions adopted by the utility model are as follows:
[0009] The utility model provides a push - head anti - detachment and sound - effect structure, including:
[0010] A pump core;
[0011] A pump head, the bottom end of which is connected to the core body of the pump core, and the outer wall surface of the lower connecting column is provided with a first wire - buckling structure;

A self-locking structure is formed between the upper end of the decorative cover and the pump head through the cooperation of the first snap line structure and the second snap line structure. When the snap line formed by the first snap line structure and the second snap line structure is screwed into or out of the mating hole, the decorative cover will be squeezed by the snap line and release kinetic energy when disengaging from the snap line, colliding with adjacent parts to produce a sound.
[0014] In some embodiments, a first limiting structure is further provided on the outer wall surface of the connecting column at the lower part of the pump head. The first limiting structure is located above the first snap line structure, and there is an active stroke of 1-5 mm between the first limiting structure and the first snap line structure.
[0015] In some embodiments, the first snap line structure and the second snap line structure are in interference fit to provide resistance when the pump head is screwed in or out.
[0016] In some embodiments, the first snap line structure includes a convex portion and a lower edge portion. The lower edge portion is connected to the lower part of the convex portion. The lower edge portion is provided with an outer edge surface inclined inward, and the lower edge portion is used to collide with the second snap line structure when releasing kinetic energy to produce a sound.
[0017] In some embodiments, the decorative cover is made of plastic material.
[0018] In some embodiments, the hardness of the first snap line structure is greater than that of the second snap line structure.
[0019] Compared with the prior art, the present utility model has at least the following beneficial effects:
[0020] Utilize the threaded cooperation relationship between the first snap line structure and the second snap line structure to form a self-locking structure, improve the connection strength between the pump head and the decorative cover, and prevent loosening; and when the snap line formed by the first snap line structure and the second snap line structure completes the screwing-in or screwing-out action, utilize the elastic deformation of the decorative cover at the second snap line structure to form kinetic energy release and restoration when disengaging from the snap line, and the second snap line structure collides with adjacent parts to produce a sound for sound effect feedback.

Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

When it is described that a specific device is connected to other devices, the specific device may be directly connected to other devices without an intermediate device, or may not be directly connected to other devices but have an intermediate device.
[0030] For technologies, methods, and devices known to those of ordinary skill in the relevant fields, they may not be discussed in detail, but where appropriate, the technologies, methods, and devices should be regarded as part of the specification.
[0031] The applicant found that:
[0032] In the traditional pressing head structure, it is generally fixed by means of threaded connection or snap connection. This is a relatively single connection method. During transportation or use, in a vibrating or impact environment, this single connection method is very likely to fail. Moreover, when the pump head is tightened or loosened from the decorative cover, the current connection method does not have a good feedback effect.
[0033] In view of this, with reference to Figures 1 to 4 , this embodiment provides a pressing head anti - detachment structure with sound effect, including:
[0034] The pump core 10, which is a traditional pump core 10;
[0035] The pump head 20, whose bottom end is connected to the core body of the pump core 10, and the outer wall surface of the lower connecting column 21 is provided with a first wire - buckling structure 22;
[0036] The decorative cover 30, which is connected to the top of the pump core 10, and the upper end surface is provided with a mating hole 31, and the outer edge surface of the mating hole 31 is provided with a second wire - buckling structure 32; The decorative cover 30, the pump head 20 and the pump core 10 can be connected into an integral body, and the pump head 20 can move up and down by pressing along the opening direction of the mating hole 31;
[0037] The first wire - buckling structure 22 is configured as a threaded structure that can be screwed into and out of the second wire - buckling structure 32. A self - locking structure is formed between the upper end of the decorative cover 30 and the pump head 20 through the cooperation of the first wire - buckling structure 22 and the second wire - buckling structure 32. The first wire - buckling structure 22 and the second wire - buckling structure 32 together form a wire buckle. Here, the wire buckle represents this threaded buckling structural form. Preferably, the wire buckle is a spiral line. When the first wire - buckling structure 22 is screwed into the wire buckle for one week, the first wire - buckling structure 22 and the second wire - buckling structure 32 can be buckled tightly. When the first wire - buckling structure 22 is screwed out of the wire buckle for one week, the first wire - buckling structure 22 and the second wire - buckling structure 32 can be unbuckled; When the pump head 20 is screwed into or out of the mating hole 31, the decorative cover 30 will be elastically deformed due to the extrusion of the wire buckle. When it breaks away from the wire buckle, the elastic deformation part of the decorative cover 30 will release kinetic energy, and the structure in this area will collide with adjacent parts to make a sound, so a feedback sound effect is emitted.
[0038] In other embodiments, the first wire - buckling structure and the second wire - buckling structure are set as a directly buckled and clamped structural form. In the traditional structural form, it is necessary to rotate the pump head many circles to pop it out from the decorative cover. When rotated to an appropriate degree, the elastic force is greater than the binding force between the first wire - buckling structure and the second wire - buckling structure, and the pump head will pop out. At this time, the first wire - buckling structure and the second wire - buckling structure will also make a sound.
[0039] As an implementation manner, a first limiting structure is further provided on the outer wall surface of the lower connecting column 21 of the pump head 20. The first limiting structure is located above the first wire buckling structure 22, and there is an active stroke of 1-5 mm between the first limiting structure and the first wire buckling structure 22. When the first wire buckling structure 22 and the second wire buckling structure 32 are in a buckled state, when subjected to vibration or impact, the second wire buckling structure 32 can perform a limited displacement between the first limiting structure and the first wire buckling structure 22, and this displacement is limited by this active stroke.
[0040] Referring to Figure 2 , preferably, the first limiting structure includes a plurality of vertical limiting ribs 23, which are evenly distributed on the outer wall surface of the connecting column 21.
[0041] Preferably, the first limiting structure is a circular rib.
[0042] As an implementation manner, the first wire buckling structure 22 and the second wire buckling structure 32 are in an interference fit to provide resistance when the pump head 20 is screwed in or out. By changing the interference amount of the interference fit, the resistance when the pump head 20 is screwed in or out is controlled.
[0043] Referring to Figure 4 , as an implementation manner, the first wire buckling structure 22 includes a convex portion 24 and a lower edge portion 25. The lower edge portion 25 is connected to the lower part of the convex portion 24. The lower edge portion 25 is provided with an outwardly inclined outer edge surface, and the cross-section of the outer edge surface is in an inverted triangular shape. The lower edge portion 25 is used to collide with the second wire buckling structure 32 when releasing kinetic energy to make a sound. The second wire buckling structure 32 is in the shape of an inverted buckle 33. When the first wire buckling structure 22 is screwed out of the second wire buckling structure 32, the second wire buckling structure 32 expands outward under extrusion. When the second wire buckling structure 32 passes over the convex portion 24, it starts to release kinetic energy and rebound, and impacts on the lower edge portion 25 to make a sound. The inclined outer edge surface of the lower edge portion 25 helps to cooperate with the inverted buckle 33 shape of the second wire buckling structure 32 and smoothly eject the pump head 20.
[0044] Preferably, the decorative cover 30 is made of plastic material.
[0045] Preferably, the hardness of the first wire buckling structure 22 is greater than that of the second wire buckling structure 32, which can ensure that the second wire buckling structure 32 can form effective deformation during the downward pressing or upward bouncing process of the pump head 20 so as to make a sound.
[0046] In summary, compared with the prior art, the above embodiments provide a head-pressing anti-loosening belt sound effect structure, which forms a self-locking structure by the threaded cooperation relationship between the first buckle line structure 22 and the second buckle line structure 32, improves the connection strength between the pump head 20 and the decorative cover 30, and prevents loosening; and when the buckle line formed by the first buckle line structure 22 and the second buckle line structure 32 completes the screwing-in or screwing-out action, the elastic deformation of the decorative cover 30 at the second buckle line structure 32 is utilized to release kinetic energy and recover when disengaging from the buckle line, and the second buckle line structure 32 collides with adjacent parts to generate a sound, which is used as sound effect feedback.
[0047] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention belong to the scope of protection required by the present invention.
