A housing assembly 100 of a food waste disposer S in accordance with a first aspect of the present invention is described below with reference to fig. 1-7.
As shown in fig. 2, the housing assembly 100 of the food waste disposer S in accordance with an embodiment of the present invention includes an annular holding ring 10, a nipple 21, and an elastic connection ring 30.
Specifically, a first injection hole 11 is formed in the peripheral wall of the annular holding ring 10, the connecting pipe 21 is arranged opposite to the annular holding ring 10 (as shown in fig. 2, the connecting pipe 21 is located right below the annular holding ring 10), a second injection hole 211 is formed in the peripheral wall of the connecting pipe 21, the elastic connecting ring 30 is flexibly connected between the annular holding ring 10 and the connecting pipe 21 in a two-shot molding mode, the annular holding ring 10 and the connecting pipe 21 are in spaced and sealed connection through the elastic connecting ring 30, namely, the elastic connecting ring 30 is molded between the annular holding ring 10 and the connecting pipe 21 in a two-shot molding mode, so that the annular holding ring 10 and the connecting pipe 21 are spaced from each other without actual direct contact, vibration generated in the whole machine operation is reduced through the elastic connecting ring 30, and vibration and noise of the shell assembly 100 are reduced.
The first injection portion 31 and the second injection portion 32 are integrally formed on the elastic connection ring 30, the first injection portion 31 formed into the elastic connection ring 30 after the fluid flows into the first injection hole 11 during injection molding, and the second injection portion 32 formed into the elastic connection ring 30 after the fluid flows into the second injection hole 211 are solidified, so that the contact areas between the elastic connection ring 30 and the annular holding ring 10 and the connecting tube 21 are further increased through filling the first injection portion 31 into the first injection hole 11 and the second injection portion 32 into the second injection hole 211, and reliable connection is ensured, namely, the elastic connection ring 30 and the annular holding ring 10 and the elastic connection ring 30 and the connecting tube 21 are not simply in contact with each other, but are respectively matched with the annular holding ring 10 and the connecting tube 21 through the elastic connection ring 30, so that the housing assembly 100 is formed into a whole, and the assembly is convenient to form without matching standard shock absorption rings and buffer pieces.
At the same time, the elastic connection ring 30 can ensure tightness between the adapter tube 21 and the annular retainer ring 10.
Here, the elastic connection ring 30 has a similar structure and function to those of the conventional shock absorbing ring and cushion member, and can absorb shock and seal, but from the microstructure, it can be seen that the elastic connection ring 30 has better sealing and shock absorbing effects than those of the shock absorbing ring and cushion member.
Specifically, the elastic connection ring 30 is connected between the adapter tube 21 and the annular holding ring 10 by means of two-shot molding, which means that when the elastic connection ring 30 is injection molded, the annular holding ring 10 and the adapter tube 21 are first at least partially placed in an injection mold, and the surfaces of the annular holding ring 10 and the adapter tube 21 constitute the inner wall surface of the mold cavity. Thus, the injection molding material liquid is filled in the cavity after being injected into the cavity, and the elastic connecting ring 30 is formed after the injection molding material is cooled. After the mold is disassembled, the annular retainer ring 10 and the adapter tube 21 are integrally connected by the elastic connection ring 30.
Here we do not have to compare the elastic connection ring 30 of the present invention with the damping rings disclosed in the prior art. The damping rings adopted in the prior art are firstly injection molded (or directly purchased in batches) and then clamped between the annular retaining ring and the connecting pipe. In some prior art, annular grooves are provided on the inner and outer peripheral sides of the damper ring, so that the outer peripheral edge of the annular retainer ring and the inner Zhou Yanka of the adapter are located in the annular grooves.
It will be appreciated that in modern part machining techniques, even if the precision of the machining of the part surface is still high, it is unavoidable that the part surface is microscopically dished and even that cracks are localized on the part surface. In the prior art, a structure that the damping ring is clamped between the annular retaining ring and the connecting pipe is adopted, and the uneven part of the surface of the damping ring is only matched with the inner wall surface of the die and is not matched with pits and cracks on the surfaces of the annular retaining ring and the connecting pipe. Particularly, when the damping ring is disassembled and assembled after molding, the surface of the part is very easy to be worn in the disassembling, so that the assembly surfaces of the annular retaining ring and the connecting pipe cannot be attached to the damping ring. Even if the annular groove is machined in the damping ring, if the connecting pipe is too heavy or vibrates too much, the connecting pipe is easy to fall off from the damping ring.
In the elastic connection ring 30 of the present invention, since there is no process of mold removal and assembly, the elastic connection ring 30 is formed with the packing at the depressions, cracks and corners of the annular holding ring 10 and the adapter tube 21, not only matching, but also abrasion due to mold removal. The elastic connecting ring 30 fills the filling materials of the pits, cracks and corners on the surfaces of the annular holding ring 10 and the connecting pipe 21, and the elastic connecting ring 30, the annular holding ring 10 and the connecting pipe 21 are firmly connected into a whole by the aid of barbs and suckers with similar sizes, so that the connecting strength is greatly increased, and the connecting ring is not easy to fall off. Moreover, as the injection molding raw materials of the elastic connecting ring 30 can be filled in the pits and cracks on the surfaces of the annular holding ring 10 and the connecting pipe 21, the sealing performance between the annular holding ring 10 and the connecting pipe 21 is better, and water leakage and sound leakage are difficult. When vibration is transmitted to the elastic connection ring 30, the buffer force point is increased due to the increase of the contact area between the elastic connection ring 30 and the annular holding ring 10 and the connecting tube 21, so that the shock absorption effect is also enhanced.
From this, take over the structural integrity of 21 subassemblies, food waste disposer S is when the operation, and annular retainer plate 10 and take over the vibrations transmission of 21 give elastic connection circle 30, and elastic connection circle 30 has fine cushioning effect, and then reduces the vibrations on the 21 subassemblies of take over and because the noise that vibrations produced, has the function of making an uproar that falls that gives sound insulation.
According to the shell assembly 100 of the food waste disposer S in the embodiment of the invention, the elastic connecting ring 30 is flexibly connected between the annular holding ring 10 and the connecting pipe 21 in a two-shot injection molding mode, and the annular holding ring 10 and the connecting pipe 21 are kept in interval and are in sealing connection through the elastic connecting ring 30, so that no actual direct contact exists between the annular holding ring 10 and the connecting pipe 21, vibration between the annular holding ring 10 and the connecting pipe 21 can be effectively reduced, noise is further reduced, meanwhile, the shell assembly 100 is integrated in structure, reliable and tight contact is matched, and good sealing performance of the inside of the shell assembly 100 is ensured.

When the elastic connecting ring 30 is injection molded, the annular holding ring 10 is placed in the mold cavity, at this time, part of the structure of the mold can extend into the annular holding ring 10 or the annular holding ring 10 is sleeved on part of the structure of the mold, and at the same time, part of the structure of the mold is stopped on the lower end face of the annular holding ring 10, so that the inner wall and the lower end face of the annular holding ring 10 are respectively in close contact with the part of the structure of the mold, and thus after injection molding raw materials of the elastic connecting ring 30 flow into the first injection hole 11 during injection molding, the injection molding is carried out again, and the first injection part 31 can be formed, so that the first injection part 31 is ensured to be flush with the inner peripheral face and the lower end face of the annular holding ring 10 respectively.
It will be appreciated that the lower end of the first injection portion 31 in the axial direction is filled into the lower end of the first injection hole 11 in the axial direction of the annular retainer ring 10 until being flush with the lower end surface of the annular retainer ring 10, so that the elastic connecting ring 30 and the annular retainer ring 10 are reliably matched, the structural surface is smoother, and uneven structural surface is avoided, and the like is formed as an integrally formed piece.
