Description

Technical Field

[0001] This utility model relates to the field of air pump equipment, and in particular to a noise-reducing silent umbrella. Background Technology

[0002] An air pump is a device that removes or adds air to a closed space. A silent umbrella is an important component installed inside the pump, creating a one-way channel within the pump's internal passages. Existing silent umbrellas have poor compatibility with air pumps, and their dimensions often don't match properly. Furthermore, when the air pump is operating, the umbrella surface flaps up and down, generating noise by striking the connecting parts at a very high frequency. Therefore, a noise-reducing silent umbrella is needed. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, a noise-reducing silent umbrella is provided.

[0004] This utility model is achieved through the following solution:

[0005] A noise-reducing silent umbrella includes a cylindrical umbrella handle with a reinforcing ball in the middle. One end of the umbrella handle is connected to a support platform, which is connected to the umbrella surface. Fine knife-like patterns are provided on the inner side of the umbrella surface.

[0006] The umbrella handle includes a first umbrella handle and a second umbrella handle. One end of the first umbrella handle is connected to a reinforcing ball, the reinforcing ball is connected to one end of the second umbrella handle, and the other end of the second umbrella handle is connected to a support platform.

[0007] The support platform includes a bottom surface, a body, and a top surface, which are connected sequentially. The bottom surface is connected to one end of the umbrella handle, and the top surface is connected to the umbrella surface.

[0008] The cross-section of the body is trapezoidal, and the diameter of the bottom surface is smaller than the diameter of the top surface.

[0009] The height of the umbrella canopy section decreases sequentially from the center outwards.

[0010] The height at the junction of the umbrella canopy and the top surface is greater than the height of the outer perimeter of the umbrella canopy.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. In this utility model, the support platform of the noise-reducing silent umbrella is set as a tapered structure, which can better accommodate the countersunk holes of connectors with similar sizes, improve the versatility of this utility model, and expand its application scope.

[0013] 2. The present invention provides a noise-reducing silent umbrella with fine knife-like texture on the inner side of the umbrella surface, which can reduce noise when it is patted. Attached Figure Description

[0016] Figure 3 This is a structural schematic diagram of a noise-reducing silent umbrella according to this utility model from another perspective;

[0017] In the diagram: 1 is the umbrella canopy, 2 is the reinforcing ball, 3 is the umbrella handle, 31 is the first umbrella handle, 32 is the second umbrella handle, 4 is the support platform, 41 is the bottom surface, 42 is the main body, 43 is the top surface, and 5 is the fine knife-like texture. Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0019] like Figure 1 As shown, a noise-reducing silent umbrella includes a cylindrical handle 3 with a reinforcing ball 2 at its center. One end of the handle 3 is connected to a support platform 4, which is connected to the umbrella surface 1. Fine grooves 5 are provided on the inner side of the umbrella surface 1. In a specific embodiment, the mold for the umbrella pin is treated with fine grooves on the inner surface of the mold, so that the inner surface of the formed umbrella pin has specific fine grooves 5, which can reduce noise when it is tapped.

[0020] like Figure 2-3 As shown, the umbrella handle 3 includes a first umbrella handle 31 and a second umbrella handle 32. One end of the first umbrella handle 31 is connected to a reinforcing ball 2, and the reinforcing ball 2 is connected to one end of the second umbrella handle 32. The other end of the second umbrella handle 32 is connected to a support platform 4. This invention incorporates a reinforcing ball to improve the structural strength of the umbrella handle, reduce the probability of handle breakage, and extend its service life.

[0021] The support platform 4 includes a bottom surface 41, a body 42, and a top surface 43, which are sequentially connected. The bottom surface 41 is connected to one end of the umbrella handle 3, and the top surface 43 is connected to the umbrella surface 1. The body 42 has a trapezoidal cross-section, and the diameter of the bottom surface 41 is smaller than the diameter of the top surface 43. The support platform 4 serves to position and support the umbrella surface. The sizes of the countersunk holes corresponding to the umbrella pins in the connectors of different users' air pumps vary. In existing support platforms 4, the side of the body 42 is a straight section, requiring a unique correspondence between the size of the support platform 4 and the size of the countersunk hole in the connector. In this invention, the side of the body 42 in the support platform 4 is changed to a slanted line, i.e., the cross-section of the body 42 is trapezoidal, which can better accommodate countersunk holes of connectors with similar sizes, improving the versatility of this invention and expanding its application scope.

[0022] The height of the umbrella surface 1 decreases progressively from the center outwards. The height at the junction of the umbrella surface 1 and the top surface 43 is greater than the height of the outer perimeter of the umbrella surface 1. Existing umbrella surfaces have a uniform thickness, meaning the height at the junction of the umbrella surface 1 and the top surface 43 is equal to the height of the outer perimeter of the umbrella surface 1. This invention, by making the thickness of the umbrella surface 1 thinner from the center outwards, effectively reduces noise. Furthermore, for an umbrella with a diameter of 6.7mm, maintaining a height difference of 0.08mm between the junction of the umbrella surface 1 and the top surface 43 and the outer perimeter of the umbrella surface 1 achieves a good noise reduction effect.

[0023] Although the technical solutions of this utility model have been described and enumerated in detail, it should be understood that modifications to the above embodiments or the adoption of equivalent alternatives are obvious to those skilled in the art. Such modifications or improvements made without departing from the spirit of this utility model are all within the scope of protection claimed by this utility model.
