Description

Technical Field

[0001] This utility model relates to the field of pet drying boxes, specifically to a sound-absorbing structure for a pet drying box. Background Technology

[0002] Currently, pet drying boxes are used to dry pets' fur. For example, the Chinese invention patent application publication number CN118923556A, "A Pet Fur Care Drying Machine," describes a pet drying box that includes a box body with a pet holding cavity inside and a door on the front of the pet holding cavity. When using a pet drying box, the pet needs to be placed inside the pet holding cavity and the door closed for a certain period of time. This inevitably leads to the pet making loud noises, which can travel outside the box. This can disturb people in pet stores or homes, and if there are other pets in the pet store, the pets outside the drying box may become agitated by the noise. Existing pet drying boxes do not have sound-absorbing structures and need to be improved. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a sound-absorbing structure for a pet drying box, which can reduce the noise transmitted from the pet housing cavity to the outside.

[0004] The objective of this utility model is achieved through the following technical solution.

[0005] The sound-absorbing structure of the pet drying box disclosed in this utility model includes a pet-containing cavity wall assembly, which includes an inner micro-perforated plate and an outer sealing plate, with a cavity formed between the inner micro-perforated plate and the outer sealing plate.

[0006] Preferably, the pet accommodating cavity wall assembly includes an outer micro-perforated plate, which is disposed between the inner micro-perforated plate and the outer sealing plate. A first resonant cavity is formed between the inner micro-perforated plate and the outer micro-perforated plate, and a second resonant cavity is formed between the outer micro-perforated plate and the outer sealing plate.

[0007] Preferably, the second resonant cavity is filled with sound-absorbing cotton.

[0008] Preferably, a support groove is provided between the inner micro-perforated plate and the outer micro-perforated plate.

[0009] Preferably, the support groove shell includes a groove bottom plate and groove side plates. The upper and lower ends of the groove bottom plate are integrally connected to one end of the corresponding groove side plate. The groove bottom plate is attached to the inner micro-perforated plate, and the other end of the corresponding groove side plate is attached to the outer micro-perforated plate. A through groove is formed on the groove bottom plate.

[0010] Preferably, the inner micro-perforated plate is a stainless steel micro-perforated plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting a pet-containing cavity wall assembly, which includes an inner micro-perforated plate and an outer sealing plate, and forming a cavity between the inner micro-perforated plate and the outer sealing plate, the noise transmitted from the pet-containing cavity to the outside can be reduced.

Detailed Implementation

[0019] The present invention will now be further described with reference to the accompanying drawings.

[0020] The sound-absorbing structure of this utility model's pet drying box, such as... Figure 1 and Figure 4 As shown, it includes a pet-containing cavity wall assembly 100, specifically, as Figure 2 and Figure 3As shown, the pet drying box includes a box body 99, a pet holding cavity 97 inside the box body 99, a door 98 corresponding to the front side of the pet holding cavity 97, and a pet holding cavity wall assembly 100 forming the pet holding cavity 97. When the door 98 is opened, the pet is placed into the pet holding cavity 97 through the front opening of the pet holding cavity 97, the door 98 is closed, and then the pet is dried.

[0021] like Figure 1 and Figure 4 As shown, the pet accommodating cavity wall assembly 100 includes an inner micro-perforated plate 1 and an outer sealing plate 3. A cavity is formed between the inner micro-perforated plate 1 and the outer sealing plate 3. That is, relative to the pet accommodating cavity 97, the inner micro-perforated plate 1 is located further inward, while the outer sealing plate 3 is located further outward. A first mesh 101 is formed on the inner micro-perforated plate 1. The sound-absorbing structure principle of the combination of the inner micro-perforated plate 1 and the outer sealing plate 3 is existing technology. Reference can be made to Chinese invention patent application publication number CN1167862C, "Ultra-wideband micro-perforated sound absorber and its manufacturing method and equipment"; Chinese utility model patent publication number CN2787715Y, "Assembled sound insulation and sound absorption barrier"; and Chinese utility model patent publication number CN203910263U, "Low-frequency sound-absorbing structure". For example, the aperture of the first mesh 101 is approximately 0.4 mm, the thickness of the inner micro-perforated plate 1 is approximately 0.4 mm, and the perforation rate of the inner micro-perforated plate 1 is approximately 1.2%. Figure 5 As shown, the first mesh 101 can be arranged in isosceles right triangles. Figure 5 The dimension "D" (meaning the length of the leg of the aforementioned isosceles right triangle) is approximately 2.9 mm. For example, as... Figure 1 and Figure 2 As shown, the sound-absorbing structures of this utility model are respectively provided on the left and right sides and the rear side of the pet housing cavity 97, such as... Figure 3 As shown, the left and right outer walls of the box 99 are actually the corresponding outer sealing plates 3. The sounds (noise) emitted by the pet are transmitted to the sound-absorbing structure of this utility model. The sound-absorbing structure of this utility model absorbs the noise, which can effectively reduce the noise transmitted to the outside of the pet drying box, that is to say, it can reduce the noise transmitted from the pet holding cavity to the outside.

[0022] Furthermore, such as Figure 1 and Figure 4 As shown, the pet accommodating cavity wall assembly 100 includes an outer micro-perforated plate 2, which is disposed between the inner micro-perforated plate 1 and the outer sealing plate 3. In other words, the outer micro-perforated plate 2 is disposed outward relative to the inner micro-perforated plate 1. A first resonant cavity 20 is formed between the inner micro-perforated plate 1 and the outer micro-perforated plate 2, and a second resonant cavity 30 is formed between the outer micro-perforated plate 2 and the outer sealing plate 3. That is to say, the first resonant cavity 20 and the second resonant cavity 30 are located within the aforementioned "cavity".

[0023] After the noise emitted by the pet is attenuated by the combined structure of the inner micro-perforated plate 1 and the first resonant cavity 20, the combined structure of the outer micro-perforated plate 2 and the second resonant cavity 30 attenuates the noise again, further reducing the noise transmitted from the pet housing cavity 97. Figure 4 As shown, specifically, the width "W1" of the first resonant cavity 20 can be approximately 18 mm, the outer micro-perforated plate 2 has a second mesh 201 with a aperture of approximately 0.7 mm, the thickness of the outer micro-perforated plate 2 is approximately 0.8 mm, the perforation rate of the outer micro-perforated plate 2 is approximately 2.5%, the hole spacing of the second mesh 201 is approximately 4.1 mm, the second mesh 201 can be arranged in equilateral triangles, and the width "W2" of the second resonant cavity 30 can be approximately 24 mm.

[0024] Furthermore, such as Figure 4 As shown, the second resonant cavity 30 is filled with sound-absorbing cotton 4. For an example of sound-absorbing cotton 4, please refer to the "Polyurethane Sound-absorbing Cotton and its Preparation Method" in Chinese Invention Patent Publication No. CN104448201B. Thus, the sound-absorbing cotton 4 can further absorb noise.

[0025] Furthermore, such as Figure 1 As shown, a support groove shell 5 is provided between the inner micro-perforated plate 1 and the outer micro-perforated plate 2. Since the inner micro-perforated plate 1 is relatively thin, the pet may kick or bump the inner micro-perforated plate 1 when its emotions fluctuate in the pet housing cavity 97. By setting the support groove shell 5, the degree of denting of the inner micro-perforated plate 1 can be reduced. The support groove shell 5 is arranged at intervals, which helps to increase the support range.

[0026] Furthermore, such as Figure 6 As shown, the supporting tank shell 5 includes a tank bottom plate 501 and a tank side plate 502. The upper and lower ends of the tank bottom plate 501 are integrally connected to one end of the corresponding tank side plate 502, as shown. Figure 1 and Figure 2 As shown, the bottom plate 501 is attached to the inner micro-perforated plate 1, and the corresponding other end of the side plate 502 is attached to the outer micro-perforated plate 2. Figure 6 As shown, a through groove 5011 is formed on the bottom plate 501 of the trough. The through grooves 5011 are arranged at intervals along the extension direction of the supporting trough shell 5, which can reduce the range of the bottom plate 501 that obstructs the first mesh 101. Figure 6 As shown, the groove side plate 502 is integrally connected with the groove outer flange 5021, such as Figure 1 As shown, the outer edge 5021 of the slot is fixedly connected to the outer micro-perforated plate 2. For example, the outer edge 5021 of the slot is welded or bonded to the outer micro-perforated plate 2.

[0027] Furthermore, the inner micro-perforated plate 1 is made of stainless steel. Since pets may get urine or feces on the inner micro-perforated plate 1, and the pet accommodating cavity 97 needs to be cleaned, the inner micro-perforated plate 1 is made of stainless steel. On the one hand, this helps to increase the structural strength of the inner micro-perforated plate 1 and reduce the extent to which the pet dents the inner micro-perforated plate 1. On the other hand, it prevents the inner micro-perforated plate 1 from rusting.
