Description

Technical Field

[0001] The present invention relates to the technical field of springs, and in particular to a novel spring and a pressing pump. Background Art

[0002] Springs are widely used in daily life. They are often used in bottles for daily necessities such as shower gel and shampoo. These bottles squeeze out their contents through a pressing action, and the key to achieving this squeezing action lies in the spring. Most existing springs are metal springs, and most are standard cylindrical springs. Using metal springs for daily necessities bottles has numerous disadvantages. For example, compared to plastic or other plastic materials, metal springs are more expensive because they are made of metal. Due to the bottle's environment, if liquid or liquid contents remain on the metal spring for a long time, the spring can easily rust, reducing its elastic force and affecting the squeezing action. Furthermore, this rust can fall off and be squeezed out along with the contents, causing contamination. Existing springs typically use a standard cylindrical structure, so the diameter of the spring's cross-section often matches the size of the object it is intended to be mounted on. Furthermore, a fixture at the bottom of the spring is required to engage the object to retain the spring in place, making it inconvenient to install and remove. At the same time, when the spring is pressed, it often does not compress and deform along the central axis but is eccentric to one side, resulting in an uneven pressing and the elastic force generated by the pressing action changes in a step-by-step manner, giving the user a feeling of uneven pressing, that is, the elastic force is not smooth, which gives the user a bad experience. Summary of the Invention

[0003] In view of the shortcomings of the prior art, one of the objectives of the present invention is to provide a new type of spring, which can solve the problem of uneven spring pressing force.

[0004] A second object of the present invention is to provide a pressing pump that can solve the problem of uneven spring pressing force.

[0005] The technical solution for achieving one of the objectives of the present invention is: a new type of spring, comprising a plurality of circular rings of different diameters, which are connected together in layers in descending order or descending order, with the centers of the circular rings on the same central axis and the circular rings arranged in parallel.

[0006] Two adjacent rings are connected by a number of spiral connecting edges, which gradually bend and spiral upward in the direction from large to small to connect the two adjacent rings together.

[0007] The included angle and inclination angle between the spiral connection edge and the connected circular ring are both acute angles. The included angle refers to the angle between the projection of the spiral connection edge on the plane where the connected circular ring is located and the circular ring. The inclination angle refers to the line-surface angle between the spiral connection edge and the plane where the connected circular ring is located.

[0008] Furthermore, the spiral connecting edge is a curved and smooth strip-shaped linear structure.

[0009] Furthermore, the connection point of the same circular ring connected by two spiral connecting edges at adjacent layers is at the same position.

[0010] Furthermore, the two included angles formed by the same spiral connecting edge and the two connected circular rings are equal, and the two inclined angles formed by the same spiral connecting edge and the two connected circular rings are also equal.

[0011] Furthermore, the intervals between the rings are equal.

[0012] Furthermore, the circular ring and the spiral connecting edge are made of plastic or plastic.

[0013] Furthermore, all the spiral connecting edges connecting two adjacent rings rise in a uniform clockwise or counterclockwise spiral direction.

[0014] Furthermore, the spiral connecting edge is located on the inner side of the ring with the larger diameter and the outer side of the ring with the smaller diameter among the two rings it connects.

[0015] Furthermore, of the two angles formed by the same spiral connecting edge and the two circular rings it connects, one angle is the angle formed by the projection of the spiral connecting edge on the plane where the connected circular rings are located and the circular rings in a clockwise direction, and the other angle is the angle formed by the projection of the spiral connecting edge on the plane where the connected circular rings are located and the circular rings in a counterclockwise direction.

[0016] The technical solution for achieving the second purpose of the present invention is: a pressing pump including the novel spring.

[0017] The beneficial effects of the present invention are as follows: the present invention can provide a smooth elastic force and can be made of plastic or plastic, which is not easy to be contaminated. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present invention will be further described below with reference to the accompanying drawings and specific implementation plans.

[0024] like Figure 1-Figure 3 As shown, a new type of spring includes a number of circular rings of different diameters, which are connected together in layers in order from large to small or from small to large in diameter. The centers of the circles of the circular rings are on the same central axis, and the circular rings are arranged in parallel. Two adjacent circular rings are connected by a number of spiral connecting ridges, and the spiral connecting ridges are curved and smooth strip-shaped linear structures. For any spiral connecting ridge, it is located on the inner side of the large circular ring of the two circular rings it connects, one end of the spiral connecting ridge is connected to the circular ring of the upper layer (which is the small circular ring), and the other end is connected to the circular ring of the lower layer (which is the large circular ring). Excluding the two circular rings in the outermost layer, the middle circular ring is connected to the circular rings of the upper and lower layers respectively through different spiral connecting ridges, that is, the middle circular ring is connected to the circular ring of the lower layer (i.e., the large circular ring) through the first spiral connecting ridge 2, and is connected to the circular ring of the upper layer (i.e., the small circular ring) through the second spiral connecting ridge 3. The spiral edge gradually curves and spirals upwards, connecting two adjacent rings. For the current spiral edge, both the included angle and the tilt angle with the two connected rings are acute angles. The two included angles and tilt angles are also equal, ranging from 10° to 80°. The included angle here refers to the angle between the projection of the spiral edge on the plane containing the rings and the rings. The tilt angle refers to the angle between the spiral edge and the plane containing the connected rings (i.e., the line-plane angle).

[0025] Among them, of the two angles formed by the same spiral connecting edge and the two connected circular rings, one angle refers to the angle formed by the projection of the spiral connecting edge on the plane where the connected circular rings are located and the circular rings in a clockwise direction, and the other angle refers to the angle formed by the projection of the spiral connecting edge on the plane where the connected circular rings are located and the circular rings in a counterclockwise direction, that is, the openings of the two angles are opposite.

[0026] All the rings and the spiral connection edges can be made of elastic materials such as plastic or plastics. Of course, they can also be made of metal.

[0027] Because the spiral connecting ridges are curved and spirally ascending and are located on the inner side of the larger ring of the two rings it connects, when an external force acts on the top or bottom ring, each ring elastically deforms under the external force and can eventually be pressed into the same plane, that is, each ring is in concentric circles on the same plane, forming a circle-by-circle structure. During this pressing process, as the angle between the spiral connecting ridges and the rings becomes smaller after being pressed, and the tilting deformation of the spiral connecting ridges also generates elastic force. In addition, the spiral connecting ridges of adjacent layers are connected to the same point to form an end-to-end connection, and the tilt angle of the two adjacent connected rings is exactly opposite. Therefore, the pressing force applied to the spiral connecting ridges of the upper layer is transmitted to the spiral connecting ridges of the lower layer, so that all the spiral connecting ridges are tilted and deformed together, making the elastic force more smoothly (steadily and smoothly) transmitted, avoiding the ring deformation and jumping stepped elastic force caused by uneven force in traditional springs. When the pressing force reaches a certain level, the inclination angle between all the spiral connecting edges and the rings is 0°, and the spiral connecting edges and all the rings are located in the same plane without overlapping (that is, the plane where the largest ring in the bottom layer is located). Similarly, after the pressure is released, the spiral connecting edges are affected by the elastic force, and the inclination angle between them and the rings gradually increases, starting to return to their original position until they are fully restored, and the rings separate and return to their original state.

[0028] The connection method of connecting adjacent spiral ridges end to end and with opposite inclination angles can better transmit force, so that all spiral ridges are stressed and deformed simultaneously. There is no sudden increase or decrease in elastic force due to the different order of force applied to each layer of rings from top to bottom. The resulting elastic force is more flexible, making it more comfortable for users to press and use. A layer is formed by two adjacent rings, so adjacent layers refer to two layers formed by three consecutive rings.

[0029] The circular rings of different diameters are connected together by spiral connecting edges and are layered, which can increase the pressing stroke compared to ordinary cylindrical springs, so that when the present invention is actually used, the substance in the bottle can be squeezed out better and faster.

[0030] In an optional embodiment, the intervals between the rings are equal.

[0031] In an optional embodiment, the first spiral connecting edge 2 and the second spiral connecting edge 3 are connected to the middle ring at the same connection point, that is, the first spiral connecting edge 2 and the second spiral connecting edge 3 are connected together at a certain position of the middle ring (that is, connected at the same position).

[0032] In an optional embodiment, all spiral connecting edges connecting two adjacent circular rings spirally rise at the same angle, for example, in a clockwise or counterclockwise direction and at equal angles.

[0033] refer to Figure 2 The new spring includes five rings, which are arranged from top to bottom in order of diameter from small to large, namely the first ring 1a, the second ring 1b, the third ring 1c, the fourth ring 1d and the fifth ring 1e. The five rings are arranged in parallel and the centers of each ring are on the same central axis. Among them, the second ring 1b, the third ring 1c and the fourth ring 1d are all intermediate rings. The fourth ring 1d is connected to the third ring 1c through the second spiral connecting ridge 3 and is connected to the fifth ring 1e through the first spiral connecting ridge 2. The first spiral connecting ridge 2 and the second spiral connecting ridge 3 are two adjacent spiral connecting ridges located on the inner and outer sides of the fourth ring 1d, so the first spiral connecting ridge 2 and the second spiral connecting ridge 3 are connected at the same position of the fourth ring 1d. The inclination angle R1 between the second spiral connecting edge 3 and the fourth circular ring 1d, and the inclination angle R2 between the second spiral connecting edge 3 and the third circular ring 1c are both acute and equal. The angles between the projection of the second spiral connecting edge 3 on the plane where the third circular ring 1c and the fourth circular ring 1d are located and the third circular ring 1c and the fourth circular ring 1d are both acute and equal.

[0034] In an optional embodiment, the number of spiral connecting edges between each adjacent ring is the same or different. For example, four spiral connecting edges are set between the fourth ring 1d and the fifth ring 1e, and each spiral connecting edge is connected between the fourth ring 1d and the fifth ring 1e at equal intervals; three spiral connecting edges are set between the first ring 1a and the second ring 1b, and each spiral connecting edge is connected between the first ring 1a and the second ring 1b at equal intervals.

[0035] The third and fourth rings 1c and 1d form a layer, designated as layer a, while the fourth and fifth rings 1d and 1e form another layer, designated as layer b. Layers a and b are adjacent layers. Therefore, the second spiral connecting rib 3 on layer a is connected end-to-end with the first spiral connecting rib 2 on layer b.

[0036] Taking all the spiral connecting edges between the fourth ring 1d and the fifth ring 1e as an example, each spiral connecting edge is arranged in a counterclockwise direction, that is, the spiral connecting edge rises in a spiral in the counterclockwise direction, and the angle between each spiral connecting edge and the fifth ring 1e is equal.

[0037] refer to Figure 4The new spring 7 of the present invention can be used in a pump, which is one of the components required for packaging bottles of many daily chemical products (shampoo, shower gel, etc.). The function of the pump is to squeeze the substance in the bottle body of the packaging bottle connected to the pump by pressing the pump head 4. During use, the new spring 7 can be installed in the compression sleeve 6 of the pump and sleeved on the fine paddle 5 located in the compression sleeve 6. When the compression sleeve 4 is pressed, the compression sleeve can act on the new spring 7 to generate elastic force.

[0038] The embodiment disclosed in this specification is merely an illustration of one aspect of the present invention. The scope of protection of the present invention is not limited to this embodiment. Any other functionally equivalent embodiments fall within the scope of protection of the present invention. Those skilled in the art can make various other corresponding changes and modifications based on the technical solutions and concepts described above, and all such changes and modifications should fall within the scope of protection of the claims of the present invention.
