Description

Technical Field

[0001] This invention relates to the field of daily necessities, and more specifically to a pet care machine. Background Technology

[0002] Many people love cats but are also bothered by the excessive amount of cat hair. Regular vacuum cleaners can't effectively remove loose hair from cats, and once it falls to the ground, it's difficult to clean up because it scatters everywhere. Ecovacs (CN201523596U) has introduced a pet-specific vacuum cleaner that uses an AC vacuum cleaner with a special comb to remove loose hair from cats and dogs, sucking it up from the comb teeth before it falls to the ground. However, this technology is more suitable for dogs than cats. Dogs are more obedient and willing to follow their owners' wishes to be groomed, and they are also more tolerant of the noise of regular vacuum cleaners. Cats, on the other hand, are more independent and difficult to get to obey their owners' wishes to be groomed quietly at a specific time and place. Additionally, many cats are sensitive and find the noise of regular vacuum cleaners unpleasant.

[0003] Therefore, the market needs a quieter vacuum cleaner that is easy to move and suitable for grooming cats anytime, anywhere, while also having enough suction power to pick up loose fur before it falls to the ground. Summary of the Invention

[0004] This invention was made to solve the above-mentioned problems, and its purpose is to provide a pet care machine.

[0005] This invention provides a pet grooming machine, characterized in that the main body of the pet grooming machine includes: an electric fan for agitating air to generate airflow and negative pressure, comprising an air inlet and an air outlet; a battery for providing power to the electric fan; a switch for controlling the circuit connection between the battery and the electric fan; a grooming component for grooming pet hair, comprising at least a base and comb teeth; a drive mechanism for driving the grooming component, causing it to switch between an extended state and a retracted state; a dust collection mechanism located upstream of the electric fan for collecting pet hair; and a movement zone near the grooming component, for moving the grooming component between the extended and retracted states. The conversion provides space; the air duct, used to circulate the airflow generated by the electric fan, has an air duct inlet and an air duct outlet. The air duct inlet is located downstream of the exercise area, and the air duct outlet is located upstream of the exercise area. At least a portion of the airflow generated by the electric fan reaches the exercise area through the air duct outlet. The distance from the electric fan inlet to the combing component is greater than the distance from the electric fan outlet to the combing component. In the extended state, the combing component extends outward from the main body of the pet grooming machine to comb the pet's fur. At this time, the exercise area is open. In the retracted state, the combing component is close to the main body of the pet grooming machine, with the comb teeth pointing towards the air duct inlet. At this time, a portion of the exercise area is blocked by the combing component.

[0006] The pet grooming machine provided by this invention may also have the following features: the air duct inlet is far from the base in the combing component and close to the downstream of the exercise area; the air duct outlet is close to the base in the combing component and also close to the upstream of the exercise area; at least a portion of the airflow generated by the electric fan reaches the exercise area through the air duct outlet; when the electric fan is started in the extended state, fresh air flows from the outside of the pet grooming machine through the exercise area into the air duct inlet, and finally reaches the exercise area through the air duct outlet; when the electric fan is started in the retracted state, the outside atmosphere enters the air duct inlet through the tip of the comb teeth, flows out through the air duct outlet, and at least a portion of the airflow flowing out of the air duct outlet enters the air duct inlet along the combing component through the tip of the comb teeth to form a circulating airflow.

[0007] The pet grooming machine provided by the present invention may also have the following features: the grooming component further includes a scraper, the comb teeth extend outward from the base, the grooming component can rotate from an extended state to a retracted state, in the extended state the scraper is close to the base and away from the comb teeth, during the rotation of the grooming component from the extended state to the retracted state the scraper moves past the root of the comb teeth to the tip of the comb teeth, in the retracted state the scraper is close to the tip of the comb teeth and blocks at least a portion of the gaps between the comb teeth.

[0008] The pet grooming machine provided by this invention may also have the following features: the drive mechanism abuts against the base and a spring is provided between the two; in the extended state, the scraper is sleeved around the base; the grooming component also includes a swinging member with two swing arms; one end of each swing arm is rotatably mounted on the main body of the grooming machine, and the other end is fixedly connected to the scraper; the comb teeth are provided on the base; when the drive mechanism pushes the base to rotate, the swinging member rotates with the base, causing the scraper to move past the root of the comb teeth to the tip of the comb teeth, and the grooming component changes from the extended state to the retracted state.

[0009] The pet care machine provided by the present invention may also have the following features: two springs are provided between the drive mechanism and the base, referred to as the first spring and the second spring respectively. When the extended state, both springs are in a free state. When the drive mechanism is compressed and moves, the first spring is compressed and the second spring is stretched. When the pressure on the drive mechanism is released, the two springs are reset respectively. The first spring pushes the drive mechanism to reset and the second spring pulls the base to reset to the extended state.

[0011] The pet grooming machine provided by the present invention may also have the following feature: the main body of the pet grooming machine is provided with a locking mechanism for keeping the grooming components in a stored state, so as to reduce the packaging volume.

[0012] The pet care machine provided by this invention may also have the following feature: wherein the battery is a rechargeable battery.

[0013] The pet grooming machine provided by this invention may also have the following features: an air inlet filter is provided upstream of the electric fan, and a thin plate with small holes is provided upstream of the air inlet filter. At least a portion of the periphery of the thin plate is sealed to the inner wall of the air duct. A gap is left between the leeward side of the perforated area of ​​the thin plate and the inner wall of the air duct. The negative pressure generated by the electric fan can reach the leeward side of the thin plate and then reach the windward side of the thin plate through the small holes, so that the air in the intake airflow can flow to the air inlet filter through the small holes on the thin plate, and the loose hair carried in the airflow can be intercepted by the small holes on the thin plate.

[0014] The role and effect of invention

[0015] The pet grooming machine according to the present invention includes an electric fan, a battery, a combing component, a drive mechanism, a dust collection mechanism, a movement area, and an air duct. The air duct is connected end-to-end through the movement area. At least a portion of the airflow flowing out of the air duct outlet can flow into the air duct inlet. In the extended state, the combing component extends outward from the main body of the pet grooming machine to comb the pet's fur. At this time, the movement area is open, and fresh air flows from the outside of the pet grooming machine through the movement area into the air duct inlet, and finally flows into the movement area through the air duct outlet, communicating with the outside atmosphere of the pet grooming machine. In the retracted state, the combing component is close to the main body of the pet grooming machine, with the comb teeth pointing towards the air duct inlet. At this time, a portion of the movement area is blocked by the combing component. Outside air enters the air duct inlet through the tips of the comb teeth, flows through the interior of the air duct, and flows out from the air duct outlet. At least a portion of the outflowing airflow travels along the combing component, passes through the tips of the comb teeth, and enters the air duct inlet to form a circulating airflow. This ensures that airflow enters the air duct inlet from both the upper and lower sides of the tips of the comb teeth, thereby effectively removing loose fur adhering to the tips of the comb teeth.

[0016] In addition, as long as the battery has enough power, users can groom their kittens anytime, anywhere without having to force the kittens to move near the pet grooming machine, making it very convenient to use.

[0017] In addition, because the distance from the air inlet of the electric fan to the combing component is greater than the distance from the air outlet of the electric fan to the combing component, that is, the air inlet of the electric fan is far away from the combing component, which is far away from the air duct inlet, the electric fan is in an inverted position relative to the air duct inlet. This ensures that the electric fan is not parallel to the air path upstream of the electric fan. This makes it easier to ensure that the pet grooming machine is relatively small and not too long, making it easy to operate the drive mechanism of the combing component with one hand.

[0027] To make the technical means, creative features, objectives and effects of the present invention easy to understand, the following embodiments, in conjunction with the accompanying drawings, will specifically illustrate the pet care machine of the present invention.

[0028] <Example>

[0029] Figure 1 This is a three-dimensional structural diagram of the pet care machine in its extended state, as described in an embodiment of the present invention. Figure 2 This is a three-dimensional structural diagram of the pet care machine in its stored state, as described in an embodiment of the present invention. Figure 3 This is a schematic diagram of the pet care machine in its stored state with the receiving cavity open, according to an embodiment of the present invention; Figure 4This is a cross-sectional schematic diagram of the pet grooming machine in its extended state according to an embodiment of the present invention.

[0030] like Figures 1 to 4 As shown, this embodiment provides a pet grooming machine 100 for grooming pets' fur, including a grooming machine body and other accessories. The grooming machine body includes a main unit shell 10, an electric fan 11, a battery 12, a switch 13, an air duct 14, a circuit board 15, a combing component 18, a drive mechanism 19, a dust collection mechanism, and a movement area 141.

[0031] The main housing 10 has a handle 101, which is hollow and serves as part of the air duct 14. A fan 11 is located inside the main housing 10 and partially within the handle 101, used to agitate air to generate airflow and negative pressure. The fan 11 is an axial-flow high-speed brushless fan. The fan 11 includes an air inlet near the air inlet filter 143 and away from the combing component 18. The fan 11 also includes an air outlet away from the air inlet filter 143 and near the combing component 18. The fan is a high-speed brushless axial-flow fan with a power of approximately 40W and a speed of 60,000 revolutions per minute or higher. This type of fan is low-noise and has a large airflow; the low noise will not frighten the kitten, and the large airflow effectively removes loose fur from the kitten's teeth.

[0032] Battery 12 is located inside handle 101 and is used to provide power to electric fan 11. Figure 4 As shown, the battery comprises two rechargeable batteries. A circuit board 15 is housed within the handle 101, electrically connected to the battery 12 and the electric fan 11, and used to control the operation of the electric fan 11. A switch 13 is located in the main housing 10 and is used to control the circuit board 15, thereby controlling the on / off state of the circuit between the battery 12 and the electric fan 11.

[0033] The grooming component 18 is at least partially located inside the main housing 10 and is used for grooming pet hair. It includes at least a plurality of comb teeth 181 with gaps between adjacent comb teeth 181. The drive mechanism 19 drives the grooming component 18, causing the grooming component to switch between an extended state and a retracted state.

[0034] The dust collection mechanism is a receiving cavity 142, which is located inside the main housing 10 as part of the air duct 14, upstream of the electric fan 11, and is used to collect pet hair. An air inlet filter 143 is also provided upstream of the electric fan 11 to filter pet hair.

[0035] like Figure 3As shown, the main unit housing 10 is also equipped with a rotatable cleaning cover 102. The collected hair in the receiving cavity 142 can be emptied by opening the cleaning cover 102. In this embodiment, the cleaning cover 102 is located on the right side of the pet grooming machine 100. The cleaning cover 102 is fastened to the main unit housing 10 by a snap-fit ​​or similar structure; after opening the snap-fit, the cleaning cover 102 can be flipped open.

[0036] The movement area 141 is located inside the main housing 10 and is connected to the outside of the main housing 10. The movement area 141 is located close to the combing member 18, providing space for the combing member 18 to switch between the extended state and the retracted state.

[0037] The air duct 14 is disposed within the main housing 10 and is used to circulate the airflow generated by the electric fan 11. It has an air duct inlet 144 and an air duct outlet 145. The air duct inlet 144 is located downstream of the motion zone 141 and away from the base 183 in the combing member 18. The air duct outlet 145 is located near the base 183 in the combing member 18 and also upstream of the motion zone 141. At least a portion of the airflow generated by the electric fan 11 reaches the motion zone 141 through the air duct outlet 145. The air duct 14 flows through the motion zone 141 from end to end, and at least a portion of the airflow flowing out of the air duct outlet 145 can flow into the air duct inlet 144. The airflow entering from the air duct inlet 144 flows sequentially through the receiving cavity 142, the inlet filter 143, and the electric fan 11, and then flows out from the air duct outlet 145. During this process, hair is filtered by the inlet filter 143 and falls into the receiving cavity 142.

[0038] like Figure 1 As shown, in the extended state, the grooming component 18 extends outward from the main unit housing 10 to groom the pet's fur. At this time, the exercise area 141 is open, and fresh air flows from the outside of the pet grooming machine 100 through the exercise area 141 into the air duct inlet 144, and finally flows into the exercise area 141 through the air duct outlet 145, connecting with the outside atmosphere of the pet grooming machine 100.

[0039] like Figure 2 As shown, in the retracted state, the combing component 18 is retracted within the movement area 141, with the comb teeth 181 pointing towards the air duct inlet 144. At this time, a portion of the movement area 141 is blocked by the combing component 18. Outside air enters the air duct inlet 144 through the tips of the comb teeth 181, flows out through the air duct outlet 145 after passing through the interior of the air duct 14, and at least a portion of the airflow from the air duct outlet 145 flows along the combing component 18, passing through the tips of the comb teeth 181 and entering the air duct inlet 144 to form a circulating airflow. Simultaneously, it blows the hair adhering to the tips of the comb teeth 181 into the air duct inlet 144. The cross-sectional area of ​​the air duct inlet 144 is preferably as large as possible, and the ventilation area of ​​the air duct is also preferably as large as possible.

[0040] Figure 5This is a right view of the pet care machine in its extended state in an embodiment of the present invention; Figure 6 This is a bottom view of the pet care machine in its extended state, according to an embodiment of the present invention.

[0041] like Figure 1 , 4 As shown in Figure 6, in this embodiment, the combing component 18 further includes a base 183 and a scraper 182. The combing component 18 can rotate from an extended state to a retracted state. In the extended state, the scraper is close to the base and away from the comb teeth. During the rotation of the combing component 18 from the extended state to the retracted state, the scraper 182 moves past the roots of the comb teeth 181 towards the tips of the comb teeth 181. In the retracted state, the scraper 182 is close to the tips of the comb teeth 81 and blocks at least a portion of the gaps between the comb teeth 181. The main function of the scraper 182 is to seal the gaps between the comb teeth, allowing the airflow to concentrate at the tips of the comb teeth. It can also squeeze the hair adhering to the comb teeth, so as to more effectively blow the hair adhering to the tips of the comb teeth into the air duct 14. This facilitates the entry of hair into the air duct 14.

[0042] like Figure 4 As shown, the base 183 is located at the edge of the motion area 141 and near the air duct outlet 145. The base 183 abuts against the drive mechanism 19, and two springs, referred to as the first spring 191 and the second spring 192, are provided between them. In the extended state, both springs are in a free state. When the drive block 17 is pressed and moves downward, the first spring 191 is compressed and the second spring 192 is stretched. After the pressure on the drive block 17 is released, the two springs return to their original positions. The first spring 191 pushes the drive block 17 upward, and the second spring 192 pulls the base 183 back to the extended state. The scraper 182 is sleeved around the base 183. The combing component 18 also includes a swinging member 184. The swinging member 184 has two swing arms, each with one end mounted on the housing 10 and capable of rotation, and the other end fixedly connected to the scraper 182. The comb teeth 182 are provided on the base 183 and extend away from the base 183. Figure 5 and Figure 6 As shown, the width of the comb teeth 182 arranged on the base 183 does not exceed the width of the air duct inlet 144, so that when in the stored state, the airflow direction flowing through all the comb teeth 182 is basically parallel to the extension direction of the comb teeth 182, which makes it easier to blow away the loose hairs adhering to the tips of the comb teeth 182.

[0043] The main body of the drive mechanism 19 is located inside the main housing 10, with a portion outside the main housing 10 serving as the drive block 17. When the user presses the drive block 17, the drive mechanism 19 pushes the base 183 to rotate, simultaneously compressing the spring between them. As the base 183 rotates, it also drives the scraper 182 to rotate, causing the scraper 182 to move past the root of the comb teeth 181 towards their tip, thus changing the combing component 18 from an extended state to a retracted state. When the user releases the drive block 17, the spring between the drive mechanism and the base resets, causing the combing component 18 to return from its retracted state to its extended state, resetting the swinging component and the drive block 17, and swinging the scraper 182 back from the tip of the comb teeth to the periphery of the base 183.

[0044] In addition, the pet grooming machine 100 may also have a locking mechanism (not shown in the figure) for keeping the grooming component 18 in the retracted state. The locking mechanism is a common locking structure and will not be described in detail here. Activating the locking mechanism keeps the grooming component 18 in the retracted state. At this time, the drive block 17 cannot drive the grooming component 18 into the extended state. Only when the locking mechanism is closed can the grooming component 18 return to the extended state.

[0045] The pet grooming machine 100 in this embodiment is used as follows:

[0046] Users can charge the battery with a charging cable. When the battery has sufficient power, the user can start the electric fan 11 via switch 13, hold the pet grooming machine 100 with handle 101, and release the combing component 18 through the locking mechanism, allowing the combing component 18 to be in the extended state. Then, the user can comb the pet's fur, especially the fur of a cat. In the extended state, the combing component 18 extends towards the front and lower part of the pet grooming machine 100, and the exercise area 141 is fully opened. Outside the pet grooming machine 100, air enters the air duct inlet 144 from the exercise area 141, flows through the receiving cavity 142 and the air inlet filter 143 to the electric fan 11, then flows through the battery 12 and the circuit board 15, and then turns and flows out of the air duct 145 to the exercise area 141, connecting with the outside atmosphere of the pet grooming machine 100.

[0047] When the tips of the comb teeth 181 of the combing member 18 are covered with loose hair, the user can press the drive block 17 with his thumb while holding the handle 101, so that the combing member 18 rotates from the extended state to the retracted state.

[0048] When in storage, the combing component 18 is basically parallel to the bottom surface of the pet grooming machine 100, and the tips of the comb teeth 181 point towards and are close to the air duct inlet 144. At this time, the combing component 18 blocks part of the movement area 141, the scraper 182 closes at least part of the gap between adjacent comb teeth, and pushes the hair on the combing component to gather towards the tips of the comb teeth. The outside air enters the air duct inlet 144 through the tips of the comb teeth 181, flows out from the air duct outlet 145 through the inside of the air duct 14, and at least part of the outflowing airflow enters the air duct inlet 144 along the combing component 18 through the tips of the comb teeth 181 to form a circulating airflow, so that airflow enters the air duct inlet 144 on both the upper and lower sides of the tips of the comb teeth 184, thereby effectively removing the loose hair stuck to the tips of the comb teeth 181.

[0049] When in the extended state, the external airflow can flow smoothly through the electric fan 11, and the electric fan can be fully cooled.

[0050] When the fan is in its stored state, some of the airflow passing through the fan 11 re-enters the air duct inlet 144, forming a circulating airflow. Because the fan 11 has low power and generates relatively little heat, the battery can sustain operation for approximately 30 minutes at full power without the fan 11 overheating. Even when stored, the air duct inlet 144 is not completely cut off from the outside atmosphere, allowing fresh outside air to enter the air duct 14 and reach the fan 11, which also helps to prevent the fan 11 from overheating.

[0051] In addition to the air duct inlets and outlets at both ends of the air duct, ventilation holes can be provided on the housing surrounding the air duct 14, allowing these ventilation holes to communicate with the air duct. When high-speed airflow passes through the air duct, due to the low fluid pressure, some external atmosphere will enter the air duct through the ventilation holes, increasing the ventilation volume inside the air duct and helping to blow away hair adhering to the tips of the comb teeth. These ventilation holes are preferably located between the air outlet of the electric fan and the combing component.

[0052] Figure 7 This is a three-dimensional structural diagram of the pet care machine after the addition of a perforated thin plate in an embodiment of the present invention; Figure 8 This is a cross-sectional view of the pet care machine after a perforated thin plate was added in an embodiment of the present invention.

[0053] like Figure 7 and Figure 8As shown, the air inlet filter 143 is located in the air duct upstream of the air inlet of the electric fan and is close to the air inlet of the electric fan. In order to facilitate one-handed operation, the pet grooming machine needs to be compact in shape, so that the cross-sectional area of ​​the air inlet filter perpendicular to the air duct is also relatively small. After hair accumulates on the upstream surface of the air inlet filter, it is easy to clog the air inlet filter and block the air duct. Therefore, in this embodiment, a thin plate 147 with small holes can also be provided upstream of the air inlet filter 143. At least a part of the periphery of the thin plate 147 is sealed to the inner wall of the air duct 14. A gap is left between the leeward side of the perforated area of ​​the thin plate 147 and the inner wall of the air duct 14. The negative pressure generated by the electric fan 11 can reach the leeward side of the thin plate 147 with small holes, and then reach the windward side of the thin plate 147 through the small holes. This allows the air in the intake airflow to flow to the air inlet filter 143 through the holes on the thin plate 147, and the loose hair carried in the airflow can be intercepted by the small holes on the thin plate 147.

[0054] Floating hair in the airflow can be intercepted by the mesh on the thin plate 147. Dust that may be carried in the airflow can penetrate the mesh but can be intercepted by the inlet filter 143. The thin plate 147 and the mesh can extend from the inlet filter 143 all the way to the air duct inlet, which is equivalent to increasing the area of ​​the inlet filter so that the receiving cavity 142 can accommodate more floating hair.

[0055] The perforated thin plate 147 can be rectangular or arc-shaped. It can be a single piece, two or more small pieces, or it can cover the entire inner wall of the air duct 14.

[0056] in addition, Figure 8 In this design, the thin plate 147 is installed by sealing the entire periphery of the thin plate 147 to the inner wall of the air duct 14. In actual use, the front part of the periphery of the thin plate 147 can also be sealed to the inner wall of the air duct 14, and the rear part of the periphery of the thin plate 147 can be integrated with the air inlet filter 143.

[0057] Because it is a rechargeable pet groomer, as long as the battery has enough power, users can groom their kittens anytime, anywhere. There is no need to force the kitten to move near the pet groomer. Instead, users can hold the pet groomer 100 close to the kitten's location, even while traveling, such as in a moving car, to groom the kitten's fur and suck up any loose hair into the receiving cavity.

[0058] Some kittens are sensitive to noise, and the noise of an axial-flow high-speed brushless motor is much lower than that of the centrifugal motor commonly used in vacuum cleaners, making it more suitable for grooming kittens.

[0059] Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to this invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.

In the extended state, the scraper is close to the base and away from the comb teeth. During the rotation of the combing component from the extended state to the retracted state, the scraper moves past the root of the comb teeth towards the tip of the comb teeth. When in the stored state, the scraper is close to the tip of the comb teeth and blocks at least a portion of the gaps between the comb teeth.

3. The pet grooming machine according to claim 2, characterized in that: in, The drive mechanism abuts against the base, and a spring is provided between the two. In the extended state, the scraper is fitted around the periphery of the base. The combing component also includes a swinging member, which has two swing arms. One end of each swing arm is rotatably mounted on the main body of the nursing machine, and the other end is fixedly connected to the scraper. The comb teeth are disposed on the base. When the drive mechanism pushes the base to rotate, the swing member follows the base to rotate, causing the scraper to move past the root of the comb teeth to the tip of the comb teeth, and the combing member changes from the extended state to the retracted state.

4. The pet grooming machine according to claim 3, characterized in that: in, Two springs, referred to as the first spring and the second spring, are provided between the drive mechanism and the base. In the extended state, both springs are in a free state. When the drive mechanism is compressed and moves, the first spring is compressed and the second spring is stretched. When the pressure on the drive mechanism is released, the two springs reset respectively. The first spring pushes the drive mechanism to reset, and the second spring pulls the base back to the extended state.

5. The pet grooming machine according to claim 1, characterized in that: in, The electric fan adopts an axial flow high-speed brushless electric fan.

6. The pet grooming machine according to claim 1, characterized in that: in, The main body of the pet grooming machine is also equipped with a locking mechanism to keep the grooming components in a stowed state, which helps to reduce the packaging volume.

7. The pet grooming machine according to claim 1, characterized in that: in, The battery is a rechargeable battery.

8. The pet grooming machine according to claim 1, characterized in that: in, An air inlet filter is provided upstream of the electric fan, and a thin plate with small holes is provided upstream of the air inlet filter. At least a portion of the periphery of the thin plate is sealed to the inner wall of the air duct. A gap is left between the leeward side of the perforated area of ​​the thin plate and the inner wall of the air duct. The negative pressure generated by the electric fan can reach the leeward side of the thin plate and then reach the windward side of the thin plate through the small holes. This allows the air in the intake airflow to flow through the small holes on the thin plate to the air inlet filter, and the floating hairs carried in the airflow can be intercepted by the small holes on the thin plate.
