Description

Technical Field

[0001] This utility model relates to the field of mask technology, specifically to an air-purifying mask for pet dogs. Background Technology

[0002] To prevent the spread of the epidemic, the flu, or smog, people have chosen to wear more effective masks for their own health and safety. At the same time, many pet dog owners also put masks on their pets to ensure that their pets are not affected by external pollutants.

[0003] Chinese utility model patent CN206381510U discloses a pet mask, including a mask body, a first strap, and a second strap. One end of the first strap and one end of the second strap are connected to the edge of one side of the mask body. Both the first and second straps are equipped with Velcro. The mask body also includes a first vent, a second vent, and a third vent. Each of the first, second, and third vents has two layers of mesh structure embedded within it, and a PM2.5 filter is disposed between each pair of mesh structures. The mask body also has a third strap, which is positioned on the mask body near the first strap and includes a third Velcro. This pet mask has the function of easy fixing and size adjustment, and the PM2.5 filter can be easily replaced. It can be used for protection against smog and dust, and can also prevent pets from biting others, achieving a multi-functional mask. However, the mask lacks a reliable ventilation system. Using a more effective ventilation system could reduce the burden on pet dogs.

[0004] Chinese invention patent CN113854179B discloses a pet disease prevention and control mask, comprising an elastic band and a sealing cover. The elastic band is connected to the sealing cover, and one side of the elastic band has an adjustment mechanism connected to the elastic band. The sealing cover has a fixing mechanism inside, which is connected to the sealing cover. The sealing cover has a collection mechanism outside, which is connected to the sealing cover. The adjustment mechanism includes a fixing ring, an adjustment buckle, a sliding groove, an adjustment wheel, a limiting block, a rotating rod, and a slot. The adjustment buckle is connected to the fixing ring. The pet disease prevention and control mask provided by this application can protect pets. Compared with ordinary pet masks, the mask provided by this application has the advantages of being able to switch and adjust the mask's state, being easy for pets to wear, and being able to handle pet drool. Although the mask has good sealing properties, it is clear that it lacks particularly effective ventilation measures and designs to handle pet drool. Pet owners may not simply choose a mask with good sealing properties; their pet's drool may also be one of the factors influencing their mask selection.

[0005] Chinese utility model patent CN206565062U discloses a pet dog anti-smog mask, including a mask body and adjustable straps at both ends of the mask body. The mask body is a cylindrical structure, which can accommodate the dog's mouth. An anti-smog filter component is set at the front end of the inner part of the cylindrical structure. In addition, at least a portion of the mask wall has elastic pleats composed of multiple longitudinal pleats for adjusting the tightness between the cylindrical structure of the mask body and the dog's mouth. This utility model, by adopting the above solution, achieves the purpose of isolating and purifying the pet dog from the outside air, protecting the dog's health. Although this mask can effectively isolate smog, it also lacks particularly effective breathability measures and a design to handle pet drool. Utility Model Content

[0047] Specifically, as a preferred example of the first filter device 2: Figure 3 As shown, the first filtration device 2 includes an exhaust cover 201, a filter element A202, and a one-way exhaust valve A203 arranged sequentially from the outside to the inside; the filter element A202 is a three-layer filter structure made of activated carbon, which can effectively filter out large particles and harmful gases in the air; the one-way exhaust valve A203 opens when exhaling and closes when inhaling.

[0048] Specifically, as a preferred example of the second filter device 3: Figure 4As shown, the second filtration device 3 includes an outer filter cover layer 301, a filter element B302, a fresh air module layer 303, a battery layer 304, and an inner filter cover layer 305 arranged sequentially from the outside to the inside.

[0049] The outer filter cover 301 is provided with an external heat dissipation hole 301a, a battery charging interface 301b, a fresh air module switch 301c, a charging and discharging indicator light 301d, and an outer filter cover 301e.

[0050] Among them, the fresh air module layer 303 is equipped with a battery charging and discharging control board 303a and a miniature ventilation fan 303b;

[0051] The battery module layer 304 is equipped with a battery 304a and an air supply connection pipe 304b. The battery 304a is electrically connected to the battery charging and discharging control board 303a and the miniature ventilation fan 303b.

[0052] The inner filter cover 305 is provided with an inner heat dissipation hole 305a and a one-way exhaust valve B305b, which are used to fix the entire second filter device 3 and connect the inside and outside of the mask body 1.

[0053] During installation, the outer filter cover 301b is aligned with the filter element B302, the miniature ventilation fan 303b, the air supply connection pipe 304b, and the one-way exhaust valve B305b in sequence; the outer heat dissipation hole 301a is aligned with the battery charging and discharging control board 303a, the battery 304a, and the inner heat dissipation hole 305a in sequence.

[0054] More specifically, filter element B302 has a three-layer filter structure and is made of activated carbon.

[0055] More specifically, the battery charging interface 301b uses a TYPE-C interface for connecting to an external power source, which allows the external power source to connect to the battery charging and discharging control board 303a via the TYPE-C interface to safely charge the battery 304a.

[0056] More specifically, the battery charge and discharge control board 303a is a lithium battery charge and discharge control board with a TYPE-C interface, preferably model TP4056.

[0057] More specifically, the miniature ventilation fan 303b uses a DC-5V miniature ventilation fan.

[0058] More specifically, battery 304a is a 3.7V rechargeable polymer lithium battery, which is responsible for powering the miniature ventilation fan 303b.

[0059] Among them, the battery charging and discharging control board 303a is used to control the charging and discharging of the battery 304a, the charging and discharging indicator light 301d is used to indicate the charging and discharging of the battery 304a, the fresh air module switch 301c is used to control the operation of the mini ventilation fan 303b, and the battery 304a is used to power the mini ventilation fan 303b. When the fresh air module switch 301c is pressed, the mini ventilation fan 303b works, continuously drawing outside air through the outer filter cover 301a and the filter element B302 into the inside of the mask body 1, accelerating the air circulation inside the mask body 1, delivering fresh and clean air to the pet dog, and letting the pet dog say goodbye to stuffiness.

[0060] In use, external air first enters the second filter device 3 through the external heat dissipation holes 301a and the external filter cover 301e on the external filter cover layer 301. After being filtered by the filter element B302 to remove large particles and harmful gases, it enters the miniature ventilation fan 303b. Subsequently, it enters the mask body 1 through the air supply connection pipe 304b of the battery layer 304 and the one-way exhaust valve B305b of the inner filter cover layer 305, and is then supplied to the pet dog for breathing.

[0061] Specifically, as a preferred example of the adjusting rope loop 4: Figure 4 As shown, the adjustable rope loop 4 includes a rope 401 and a rope buckle 402. The two ends of the rope 401 are fixedly connected to the two sides of the mask body 1, and the rope buckle 402 is threaded on the rope 401 to adjust the length of the rope 401.

[0062] More specifically, the rope buckle 402 is a rectangular structure that is threaded onto the rope 401 through an opening in it.

[0063] Specifically, as a preferred example of absorbent cotton pack 5: such as Figure 5 As shown, the absorbent cotton pack 5 includes an absorbent cotton pack body 501, a fixing buckle 502, and a lower wing portion 503. The fixing buckle 502 is located on one side of the absorbent cotton pack body 501, and the lower wing portion 503 is located at the lower part of the absorbent cotton pack body 501. Both the absorbent cotton pack body 501 and the lower wing portion 503 are attached to the inside of the mask body 1 and fit against the face of the pet dog to absorb the pet dog's saliva.

[0064] More specifically, such as Figure 6 As shown, the absorbent cotton body 501 and the lower wing portion 503 both contain edible-grade absorbent cotton 504, and the edible-grade absorbent cotton 504 is wrapped with a first outer gauze 505 and a second outer gauze 506. The second outer gauze 506 is provided with a Velcro male patch 507 for sticking and cooperating with the inner side of the mask body 1, and the inner surface of the mask body 1 is provided with a Velcro female patch 508 for sticking and cooperating with the Velcro male patch 507.

[0065] The use of Velcro 507 and Velcro 508 facilitates the replacement of the absorbent cotton pack 5. When it is necessary to replace the absorbent cotton pack 5, you can first pinch the fixing buckle 502 on the old absorbent cotton pack 5 and pull it outwards, so that the absorbent cotton pack body 501 and the lower wing portion 503 of the old absorbent cotton pack 5 are pulled off from the inner wall of the mask body 1. Then, you can pinch the fixing buckle 502 on the new absorbent cotton pack 5 and stick the absorbent cotton pack body 501 and the lower wing portion 503 of the new absorbent cotton pack 5 to the inner wall of the mask body 1. In this way, the replacement of the old and new absorbent cotton packs 5 can be achieved.

[0066] The working principle of the air-purifying mask for pet dogs provided in this embodiment is as follows:

[0067] When using the mask, first place the mask body 1 over the dog's mouth, then adjust the fit between the mask body 1 and the dog's mouth. Next, adjust the length of the adjustment loop 4 as needed, and then tie the adjustment loop 4 around the dog's neck. The dog can then inhale through the air inlet and exhale through the air outlet on the mask body 1. When inhaling, the air is first purified by the second filter device 3 at the air inlet, and then the purified air is drawn into the mask body 1 for the dog to use. When exhaling, the dog can directly expel the carbon dioxide gas exhaled through the air outlet. At the same time, harmful substances in the outside air can be filtered by the first filter device 2 and allowed to enter the mask body 1, thus protecting the dog's health.

[0068] Finally, it should be noted that the above description is only an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
