Example 1:
as shown in fig. 1, the present embodiment provides a noise reduction cup cover 100, which is used for being matched with a cup body of a wall breaking machine, and mainly comprises a cup cover body 110 and a feeding cover 120, wherein the feeding cover 120 is matched with a feeding hole on the cup cover body 110.
Specifically, as shown in fig. 1, 2 and 3, the feeder cap 120 includes a lower noise reduction assembly 121 and an upper noise reduction assembly 122. The lower noise reduction assembly 121 comprises a lower cover plate 1211, an inner cylinder 1212 and an outer cylinder 1213, wherein one end of the inner cylinder 1212 and one end of the outer cylinder 1213 are respectively connected with the lower cover plate 1211, the outer cylinder 1213 is sleeved on the inner cylinder 1212, and a containing space 1214 is formed between the outer cylinder 1213 and the inner cylinder 1212; the lower cover 1211 is further provided with a first through hole, which communicates with the inner cylinder 1212. The upper noise reduction assembly 122 comprises an upper cover plate 1221, a middle cylinder 1222 and an anti-scalding ring 1223, wherein one end of the middle cylinder 1222 is connected with the middle part of the upper cover plate 1221, and one end of the side cylinder 1223 is connected with the edge of the upper cover plate.
In this embodiment, the upper noise reduction component 122 and the lower noise reduction component 121 are made of sound absorbing materials, or the inner wall is attached with sound absorbing materials, and the two components are integrally formed. When the two are assembled, the free end of the outer cylinder 1213 is connected with the upper cover plate 1221 and sleeved on the middle cylinder 1222, the free end of the middle cylinder 1222 is arranged with the lower cover plate 1211 in a clearance way, the free end of the inner cylinder 1212 is arranged with the upper cover plate 1221 in a clearance way, the upper cover plate 1221 is provided with a second through hole 1225, and the second through hole 1225 communicates the accommodating space 1214 with the outside. The first sound-deadening chamber 1301 is a semi-closed containing space surrounded by the outer wall of the inner cylinder 1212, the inner wall of the middle cylinder 1222, part of the upper cover plate 1221 and the lower cover plate 1211, and the second sound-deadening chamber 1302 is a semi-closed containing space surrounded by the outer wall of the middle cylinder 1222, the side wall of the outer cylinder 1213 and part of the lower cover plate 1211.
Further, in this embodiment, the inner cylinder 1212, the outer cylinder 1213, and the intermediate cylinder 1222 are circular cylinders. The upper end cover and the lower end cover are circular end covers, and one end of the outer cylinder 1213 is connected with the edge of the lower cover plate 1211. In other embodiments, the inner cylinder 1212, outer cylinder 1213, and intermediate cylinder 1222 may be other cylindrical structures, such as square cylinders. The working principle of the noise reduction cup cover 100 in this embodiment is as follows:
in use, the lid 100 is placed over the cup body, and the tool bit is rotated at high speed and produces a large amount of medium-high frequency noise during processing of food, which is reflected and transmitted with steam from the cup body under high pressure to the outside through the feeding cap 120. Noise is finally transmitted to the external environment through the inner cylinder 1212, the first noise elimination cavity 1301, the noise reduction hole 1224, the second noise elimination cavity 1302, the noise reduction hole 1224 and the second through hole 1225 in sequence. After noise passes through the silencing channel, the times of reflection and interference are increased, and the noise is fully contacted with the sound absorbing material, so that the silencing coefficient and silencing quantity of the sound absorbing material are improved, and medium-high frequency noise energy and sound attenuation are realized; the cross section of the noise reduction channel is continuously suddenly changed from the cup body to the inner cylinder 1212, from the inner cylinder 1212 to the first noise reduction cavity 1301, and from the noise reduction hole 1224 to the second noise reduction cavity 1302, so that mismatch of acoustic impedances is caused, interference reflection and other phenomena occur at the impedance suddenly changed position of the low-frequency noise, the acoustic energy is consumed, and the low-frequency noise is weakened.
In addition, during the working process of the wall breaking machine for cooking food, more water vapor is generated in the cup body, the water vapor is condensed into water after passing through the feeding cover 120, the condensed water is accumulated in the accommodating space 1214 of the cup cover, and finally, the gap between the middle cylinder 1222 and the lower end cover is sealed to form a water seal. The water seal with sealing effect forms a part of the silencing structure and assists in noise reduction, compared with the impedance composite silencing structure with a complex structure, the sealing technology with higher requirements and cost is avoided, and the complex manufacturing process is avoided. After the noise reaches the water seal position, the water seal is impacted, the sound wave energy is weakened by the water seal, and finally, the sound wave energy is transmitted out after passing through the water seal; another portion of the noise enters the second muffling cavity 1302 through the noise reduction holes 1224, increasing the rate of resistance mutation, further increasing the muffling effect.
Because the steam is condensed into water to be stored, the steam can be prevented from directly discharging outside to scald the user, and in addition, the storage of the condensed water can prevent the steam from flowing to a host machine or a working table after being discharged and liquefied into water. Meanwhile, the anti-scalding ring 1223 of the upper noise reduction assembly 122 is isolated from the feeding cover 120 by air, so that heat generated during cooking or condensation can be well isolated, and when the feeding operation is performed, the anti-scalding ring 1223 is held by a hand to pull up the feeding cover 120, the hand can be prevented from being scalded.
Because the inner cylinder 1212 is higher, condensed water can be prevented from being sucked into processed food due to backward suction, and the flavor of the food is ensured; the higher inner barrel 1212 allows only steam to pass through, which can prevent boiling food ingredients from entering the muffler device of the feed cap 120, avoid blocking the muffler channel, and avoid cleaning the internal structure of the feed cap 120. After each use, the wall breaking machine cover 100 is reversely placed on the working table, and the condensed water can be automatically discharged along the second through hole.
Therefore, the measures can reduce noise, play a role in condensation and scalding prevention, and further improve the use experience of a user.
It should be noted that, in this embodiment, the "upper" and "lower" are used for convenience of description, and reference is made to the accompanying drawings, and when the direction of the accompanying drawings changes, the upper and lower directions will change correspondingly.
Example 2:
as shown in fig. 4, this embodiment provides another noise reduction cup cover 200 of wall breaking machine, which is different from embodiment 1 in that a cone 210 and a water adding device 230 are added.
The cone 210 includes a large end and a small end, the large end being connected with the free end of the inner cylinder 1212; the wall of the conical cylinder 210 is provided with a through hole; the water adding device 230 is used for automatically adding water to the accommodating space 1214 to form a water seal.
Referring to fig. 5, the water adding device 230 includes a water adding box 234, a first link 231, a second link 232, a third link 233, a rubber sheet 236, and a water adding valve 235, wherein an edge of the rubber sheet 236 is connected with the cone 210; and the rubber sheet 236 is recessed toward the inside of the cone 210. One end of the first link 231 is connected with the middle of the rubber sheet 236, the other end of the first link 231 is hinged with the second link 232, the free end of the second link 232 is hinged with the third link 233, and the free end of the third link 233 is connected with the water adding valve 235.
The second link 232 is further provided with a rotation shaft, and the second link 232 is rotatably connected to the intermediate cylinder 1222 through the rotation shaft.
The upper cover plate 1221 is provided with a water injection hole, which communicates the water adding box 234 with the accommodation space 1214. The water filling valve 235 includes a baffle and a connecting shaft, and when the baffle is matched with the water filling hole, the baffle prevents water in the water filling box 234 from flowing into the accommodating space 1214. And the connecting shaft is vertically connected with the baffle, the connecting shaft is arranged in the water injection hole, and the spring is sleeved on the connecting shaft.
One end of the spring is connected with the upper cover plate 1221, and the other end is connected with the baffle plate. In a natural state, the water injection hole is blocked by the baffle plate, and the rubber sheet 236 can be opened by the first link 231, the second link 232 and the third link 233.
The working principle of the noise reduction cup cover 200 of the wall breaking machine provided in this embodiment is basically similar to that in embodiment 1. Specifically, when the temperature of the fluid in the cup 410 is low, the amount of steam in the cup 410 is small, and it is difficult for the steam to condense and collect as a water seal in the accommodation space 1214. At this time, after the noise reduction cup cover 200 of the wall breaking machine 400 in the embodiment is adopted, when middle-high frequency noise passes through the conical barrel 210, the energy is gathered to the small end and then transmitted to the rubber sheet 236, the noise drives the rubber sheet 236 to move, the rubber sheet 236 drives the second connecting rod 232 to rotate through the first connecting rod 231, and the second connecting rod 232 forms a lever structure due to the arrangement of a rotating shaft on the second connecting rod 232; because the rotating shaft is close to the first connecting rod 231, the lever structure amplifies the movement amplitude of the first connecting rod 231, the movement amplitude of one end, connected with the second connecting rod 232 and the third connecting rod 233, of the lever structure is relatively large, and the third connecting rod 233 drives the baffle to move downwards, so that water in the water adding box 234 can be discharged and flows into the accommodating space 1214 to form a water seal.
In addition, since the rubber sheet 236 is made of a rubber sheet having a certain thickness, the vibration thereof does not cause noise. Also, since the rubber sheet 236 is depressed downward, the middle and high frequency noise more easily drives the rubber sheet 236 upward, thereby opening the water valve 235. In addition, since the wall of the cone 210 is provided with the through hole, steam and part of noise can also be transmitted to the outside through the micropore on the cone 210, so that a closed space is prevented from being formed in the cup body, and the noise and the steam cannot reach the return resonance of the noise and the steam in the closed space due to the fact that the noise and the steam are transmitted out.
