Description

Technical Field

[0001] The present invention relates to the field of daily necessities, and particularly to a pet care machine. Background Art

[0002] Many people like cats, but are troubled by too much cat hair. Ordinary vacuum cleaners cannot suck the loose hair from cats. After the loose hair falls to the ground, it is difficult to clean because it scatters everywhere. CN201523596U by Ecovacs launched a special vacuum cleaner for pets. With an AC vacuum cleaner plus a specific comb, it can comb the loose hair from cats and dogs and suck the loose hair on the comb teeth into the vacuum cleaner before the loose hair falls to the ground. However, this technology is more suitable for dogs and less suitable for cats. Because dogs are more obedient and willing to obey the master's will, they will walk to the side of the vacuum cleaner to accept grooming and are also more likely to accept the noise of ordinary vacuum cleaners. However, cats are more independent and it is difficult to make them obey the master's will at any time and quietly accept grooming at a specific time and place. In addition, many cats are also more sensitive and difficult to accept the noise of ordinary vacuum cleaners.

[0003] Therefore, there is a need in the market for a quieter vacuum cleaner that is easy to move, suitable for combing cat hair at any time and place, and has sufficient suction to suck away the loose hair before it falls to the ground. Summary of the Invention

[0004] The present invention is made to solve the above problems, and aims to provide a pet care machine.

[0005] The present invention provides a pet care machine having the following features. The main body of the pet care machine includes: a blower for agitating air to generate air flow and negative pressure, including a blower air inlet and a blower air outlet; a battery for supplying electrical energy to the blower; a switch for controlling the on-off of the circuit between the battery and the blower; a combing member for combing pet hair, including at least a base and comb teeth; a driving mechanism for driving the combing member to switch between an extended state and a retracted state; a dust collection mechanism located upstream of the blower for accommodating pet hair; a movement area near the combing member for providing space for the combing member to switch between the extended state and the retracted state; an air duct for circulating the air flow generated by the blower, having an air duct inlet and an air duct outlet, the air duct inlet being close to the downstream of the movement area, and the air duct outlet being close to the upstream of the movement area, at least a part of the air flow generated by the blower reaches the movement area through the air duct outlet. Among them, the distance from the blower air inlet to the combing member is greater than the distance from the blower air outlet to the combing member. In the extended state, the combing member extends outward from the main body of the pet care machine for combing pet hair, and at this time the movement area is open. In the retracted state, the combing member is close to the main body of the pet care machine, and the comb teeth point to the air duct inlet, and at this time a part of the movement area is blocked by the combing member.

[0006] In the pet care machine provided by the present invention, it may further have the following features: among them, the air duct inlet is far from the base in the combing member and close to the downstream of the movement area, the air duct outlet is close to the base in the combing member and also close to the upstream of the movement area. At least a part of the air flow generated by the electric fan reaches the movement area through the air duct outlet. When the electric fan is started in the extended state, fresh air flows through the movement area from outside the pet care machine into the air duct inlet and finally reaches the movement area through the air duct outlet. When the electric fan is started in the stored state, the outside atmosphere enters the air duct inlet through the tips of the comb teeth, flows out through the air duct from the air duct outlet, and at least a part of the air flow flowing out of the air duct outlet forms a circulating air flow along the combing member through the tips of the comb teeth and into the air duct inlet.

[0007] In the pet care machine provided by the present invention, it may further have the following features: among them, the combing member further includes a scraper. The comb teeth extend outward from the base, and the combing member can rotate from the extended state to the stored state. In the extended state, the scraper is close to the base and far from the comb teeth. During the rotation of the combing member from the extended state to the stored state, the scraper moves over the root of the comb teeth towards the tips of the comb teeth. In the stored state, the scraper is close to the tips of the comb teeth and blocks at least a part of the gaps between the comb teeth.

[0008] In the pet care machine provided by the present invention, it may further have the following features: among them, the driving 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 combing member further includes a swing member. The swing member has two swing arms. One ends of the two swing arms are respectively rotatably installed on the main body of the care machine, and the other ends are fixedly connected to the scraper. The comb teeth are arranged on the base. When the driving mechanism pushes the base to rotate, the swing member rotates with the base, driving the scraper to move over the root of the comb teeth towards the tips of the comb teeth, and the combing member is converted from the extended state to the stored state.

[0009] In the pet care machine provided by the present invention, it may further have the following features: among them, two springs are provided between the driving mechanism and the base, which are respectively denoted as the first spring and the second spring. In the extended state, both springs are in a free state. When the driving mechanism moves after being pressed, the first spring is compressed and the second spring is stretched. When the pressure on the driving mechanism is released, the two springs are respectively reset. The first spring pushes the driving mechanism to reset, and the second spring pulls the base to reset to the extended state.

[0010] In the pet care machine provided by the present invention, it may further have the following features: among them, the electric fan adopts an axial-flow high-speed brushless electric fan.

[0011] In the pet care machine provided by the present invention, it may further have the following features: among them, a locking mechanism is further provided on the main body of the pet care machine for keeping the combing member in the stored state, which is convenient for reducing the packaging volume.

[0012] In the pet care machine provided by the present invention, it may further have the following feature: wherein, the battery is a rechargeable battery.

[0013] In the pet care machine provided by the present invention, it may further have the following feature: wherein, an air inlet filter is provided upstream of the electric fan, a thin plate with small holes is provided upstream of the air inlet filter, at least a part of the periphery of the thin plate is hermetically connected to the inner wall of the air duct, a gap is left between the leeward surface 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 surface of the thin plate, and then reach the windward surface of the thin plate through the small holes, so that the air in the inhaled air flow can flow through the small holes on the thin plate to the air inlet filter, and the floating hairs entrained in the air flow can be intercepted by the small holes on the thin plate.

[0014] Functions and effects of the invention

[0015] According to the pet care machine involved in the present invention, because it includes an electric fan, a battery, a grooming member, a driving mechanism, a dust collection mechanism, a movement area and an air duct, the air duct is connected end to end through the movement area, and at least a part of the air flow flowing out of the air duct outlet can flow into the air duct inlet. In the extended state, the grooming member extends outward from the main body of the pet care machine and can groom the pet's hair. At this time, the movement area is open, and fresh air flows from outside the pet care 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 atmosphere outside the pet care machine. In the stored state, the grooming member is close to the main body of the pet care machine, and the comb teeth point to the air duct inlet. At this time, a part of the movement area is blocked by the grooming member, and the outside atmosphere enters the air duct inlet through the tips of the comb teeth, flows out from the air duct outlet through the inside of the air duct, and at least a part of the outflow air flow forms a circulating air flow along the grooming member through the tips of the comb teeth and enters the air duct inlet, so that air flows into the air duct inlet on both the upper and lower sides of the tips of the comb teeth, thereby effectively peeling off the floating hairs sticking to the tips of the comb teeth.

[0016] In addition, as long as the battery has sufficient power, the user can groom the kitten at any time and any place without forcing the kitten to move near the pet care machine, which is very convenient to use.

[0017] In addition, because the distance from the air inlet of the electric fan to the grooming member is greater than the distance from the air outlet of the electric fan to the grooming member, that is, the air inlet of the electric fan is far from the grooming member, which is also far from the air duct inlet, so that the electric fan is in an inverted posture relative to the air duct inlet, ensuring that the electric fan is not parallel to the air path upstream of the electric fan, which is convenient to ensure that the pet care machine has a relatively small shape and is not too long, and is convenient to operate the driving mechanism of the grooming member with one hand.

[0028] <Embodiment>

[0029] Figure 1 It is a schematic three - dimensional structure diagram of the pet care machine in the extended state in the embodiment of the present invention; Figure 2 It is a schematic three - dimensional structure diagram of the pet care machine in the storage state in the embodiment of the present invention; Figure 3 It is a schematic diagram of the pet care machine when the accommodation cavity is opened in the storage state in the embodiment of the present invention; Figure 4It is a schematic cross-sectional view of the pet care machine in the extended state in the embodiment of the present invention

[0030] As Figures 1 to 4 shown, this embodiment provides a pet care machine 100 for grooming the hair of a pet, including a care machine main body and other accessories. The care machine main body includes a main housing 10, a blower 11, a battery 12, a switch 13, an air duct 14, a circuit board 15, a combing member 18, a driving mechanism 19, a dust collection mechanism, and a movement area 141.

[0031] The main housing 10 has a handle 101, the inside of the handle 101 is hollow and serves as a part of the air duct 14. The blower 11 is arranged inside the main housing 10 and partially located inside the handle 101, and is used to agitate air to generate air flow and negative pressure. The blower 11 is an axial-flow high-speed brushless blower. The blower 11 includes a blower air inlet, which is close to the air inlet filter 143 and far from the combing member 18. The blower 11 also includes a blower air outlet, which is far from the air inlet filter 143 and close to the combing member 18. The blower is a high-speed brushless axial-flow blower with a power of about 40W and a rotation speed of 60,000 revolutions per minute or higher. This blower has low noise and a large air volume. The low noise will not startle the kitten, and the large air volume can effectively blow away the floating hair at the tooth tips.

[0032] The battery 12 is arranged inside the handle 101 and is used to supply electrical energy to the blower 11. As Figure 4 shown, the battery includes two rechargeable batteries. The circuit board 15 is arranged inside the handle 101, is electrically connected to the battery 12 and the blower 11, and is used to control the operation of the blower 11. The switch 13 is arranged on the main housing 10 to control the circuit board 15, and further control the on-off of the circuit between the battery 12 and the blower 11.

[0033] The combing member 18 is at least partially located inside the main housing 10 and is used to comb the hair of the pet. It includes at least a plurality of comb teeth 181, and there are gaps between adjacent comb teeth 181. The driving mechanism 19 is used to drive the combing member 18 so that the combing member can be switched between the extended state and the retracted state.

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

[0035] As Figure 3As shown, a cleaning cover 102 that can be rotated and opened is also provided on the main housing 10. By opening the cleaning cover 102, the hair collected in the accommodation cavity 142 can be poured out. In this embodiment, the cleaning cover 102 is disposed at the right side position of the pet care machine 100. The cleaning cover 102 and the main housing 10 are fastened together through structures such as buckles. After the buckles are opened, the cleaning cover 102 can be flipped open.

[0036] The movement area 141 is provided inside the main housing 10 and is in communication with the outside of the main housing 10. The movement area 141 is disposed close to the grooming member 18 to provide space for the grooming member 18 to switch between the extended state and the retracted state.

[0037] The air duct 14 is provided inside the main housing 10 for circulating the air flow generated by the electric blower 11, and has an air duct inlet 144 and an air duct outlet 145. The air duct inlet 144 is close to the downstream of the movement area 141 and far from the base 183 of the grooming member 18. The air duct outlet 145 is close to the base 183 of the grooming member 18 and also close to the upstream of the movement area 141. At least a part of the air flow generated by the electric blower 11 reaches the movement area 141 through the air duct outlet 145. The air duct 14 is in end-to-end connection through the movement area 141. At least a part of the air flow flowing out from the air duct outlet 145 can flow into the air duct inlet 144. The air flow entering from the air duct inlet 144 flows through the accommodation cavity 142, the air inlet filter 143, and the electric blower 11 in sequence and then flows out from the air duct outlet 145. During this process, the hair is filtered by the air inlet filter 143 and falls into the accommodation cavity 142.

[0038] As Figure 1 shown, in the extended state, the grooming member 18 extends outward from the main housing 10 for grooming pet hair. At this time, the movement area 141 is open, and fresh air penetrates through the movement area 141 from the outside of the pet care machine 100 and flows into the air duct inlet 144, and finally flows into the movement area 141 through the air duct outlet 145, being in communication with the atmosphere outside the pet care machine 100.

[0039] As Figure 2 shown, in the retracted state, the grooming member 18 is retracted into the movement area 141, and the comb teeth 181 point to the air duct inlet 144. At this time, a part of the movement area 141 is blocked by the grooming member 18. The outside atmosphere enters the air duct inlet 144 through the tips of the comb teeth 181, flows out from the inside of the air duct 14 through the air duct outlet 145, and at least a part of the air flow flowing out from the air duct outlet 145 forms a circulating air flow along the grooming member 18 through the tips of the comb teeth 181 and enters the air duct inlet 144, and at the same time 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 5It is the right view of the pet care machine in the extended state in the embodiment of the present invention; Figure 6 It is the bottom view of the pet care machine in the extended state in the embodiment of the present invention.

[0041] As Figure 1 , 4 -6 shows that in this embodiment, the grooming member 18 further includes a base 183 and a scraper 182. The grooming member 18 can rotate from the extended state to the 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 member 18 from the extended state to the retracted state, the scraper 182 moves over the root of the comb teeth 181 towards the tip of the comb teeth 181; in the retracted state, the scraper 182 is close to the tip of the comb teeth 81 and blocks at least a part of the gaps between the comb teeth 181. The main function of the scraper 182 is to close the gaps between the comb teeth, make the air flow concentrate at the tips of the comb teeth, and at the same time can squeeze the hair adhered to the comb teeth, so as to more effectively blow the hair adhered to the tips of the comb teeth into the air duct 14. Thus, it is convenient for the hair to enter the air duct 14.

[0042] As Figure 4 shown, the base 183 is arranged at the edge of the movement area 141 and close to the air duct outlet 145. The base 183 abuts against the driving mechanism 19, and two springs are provided between the two, which are respectively denoted as the first spring 191 and the second spring 192. In the extended state, both springs are in a free state. When the driving block 17 moves downward after being pressed, the first spring 191 is compressed and the second spring 192 is stretched. After the pressure on the driving block 17 is released, the two springs are reset respectively. The first spring 191 pushes the driving block 17 upward, and the second spring 192 pulls the base 183 to reset to the extended state. The scraper 182 is sleeved around the base 183. The grooming member 18 further includes a swing member 184. The swing member 184 has two swing arms. Both ends of the two swing arms are installed on the housing 10 and can rotate, and the other ends are fixedly connected to the scraper 182. The comb teeth 182 are arranged on the base 183 and extend away from the base 183. As Figure 5 and Figure 6 shown, the width of the comb teeth 182 arranged left and right on the base 183 does not exceed the left and right width of the air duct inlet 144, so that in the retracted state, the air flow direction flowing through all the comb teeth 182 is basically parallel to the extension direction of the comb teeth 182, which is convenient for blowing away the floating hair adhered to the tips of the comb teeth 182.

[0043] The main body of the driving mechanism 19 is arranged inside the main housing 10, and a part is located outside the main housing 10 as the driving block 17. When the user presses the driving block 17, the driving mechanism 19 pushes the base 183 to rotate, and at the same time compresses the spring between the two. The base 183 drives the scraper 182 to rotate while rotating, so that the scraper 182 moves over the root of the comb teeth 181 towards the tip of the comb teeth 181, and the combing member 18 is converted from the extended state to the retracted state. When the user releases the driving block 17, the spring between the driving mechanism and the base resets, driving the combing member 18 to reset from the retracted state to the extended state, so that the swing member and the driving block 17 reset, and the scraper 182 swings back from the tip of the comb teeth to the periphery of the base 183.

[0044] In addition, the pet care machine 100 may also have a locking mechanism (not shown in the figure) for holding the combing member 18 in the retracted state. The locking mechanism is a common locking structure and will not be elaborated here. Starting the locking mechanism can hold the combing member 18 in the retracted state. At this time, the driving block 17 cannot drive the combing member 18 into the extended state. Only after the locking mechanism is turned off can the combing member 18 reset to the extended state.

[0045] The usage process of the pet care machine 100 in this embodiment is as follows:

[0046] The user can charge the battery with a charging cable. When the battery has sufficient power, start the electric fan 11 through the switch 13, hold the pet care machine 100 through the handle 101, release the combing member 18 through the locking mechanism, and let the combing member 18 be in the extended state. Then, the hair on the pet's body can be combed, especially the hair of a kitten. In the extended state, the combing member 18 extends forward and downward of the pet care machine 100, the movement area 141 fully opens, the air outside the pet care machine 100 enters the air duct inlet 144 from the movement area 141, flows through the accommodation cavity 142 and the air inlet filter 143 in the air duct 14 to reach 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 14 from the air duct outlet 145 to the movement area 141, communicating with the atmosphere outside the pet care machine 100.

[0047] When the tip of the comb teeth 181 of the combing member 18 is stained with floating hair, while holding the handle 101, the user can press the driving block 17 with the thumb to make the combing member 18 rotate and change from the extended state to the retracted state.

[0048] In the storage state, the grooming member 18 is substantially parallel to the bottom surface of the pet grooming machine 100, the tips of the comb teeth 181 point to and are close to the air duct inlet 144. At this time, the grooming member 18 blocks a part of the movement area 141, and the scraper 182 closes at least a part of the gaps between adjacent comb teeth. Meanwhile, the hair on the grooming member is pushed to gather at 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 after passing through the inside of the air duct 14. At least a part of the outflowing air flow forms a circulating air flow along the grooming member 18 through the tips of the comb teeth 181 and enters the air duct inlet 144, so that air flows into the air duct inlet 144 on both the upper and lower sides of the tips of the comb teeth 184, thereby effectively peeling off the floating hair adhering to the tips of the comb teeth 181.

[0049] In the extended state, the outside air flow can smoothly flow through the electric fan 11, and the electric fan can be fully cooled.

[0050] In the storage state, a part of the air flow flowing through the electric fan 11 enters the air duct inlet 144 again to form a circulating air flow. Because the power of the electric fan 11 is low and the heat generation is relatively small, when operating at full power, the battery life is about 30 minutes, and the electric fan 11 will not overheat. In the storage state, the communication between the air duct inlet 144 and the outside air is not completely cut off, so there is still fresh outside air entering the air duct 14 and reaching the electric fan 11, which can also inhibit the overheating of the electric fan 11.

[0051] In addition to the air duct inlet and the air duct outlet at both ends of the air duct, ventilation holes can also be provided on the housing enclosing the air duct 14 to connect these ventilation holes with the air duct. When the high-speed air flow flows through the air duct, because the pressure of the fluid is low, part of the outside air will enter the air duct from the ventilation holes, increasing the ventilation volume inside the air duct and helping to blow away the hair adhering to the tips of the comb teeth. These ventilation holes are preferably provided between the air outlet of the electric fan and the grooming member.

[0052] Figure 7 It is a schematic three-dimensional structure diagram of the pet grooming machine in the embodiment of the present invention after adding a perforated thin plate; Figure 8 It is a schematic cross-sectional structure diagram of the pet grooming machine in the embodiment of the present invention after adding a perforated thin plate.

[0053] Such as Figure 7 and Figure 8As shown in the figure, the intake filter 143 is located in the air duct upstream of the air inlet of the blower fan and close to the air inlet of the blower fan. To facilitate single-handed operation, the pet grooming machine needs to be small in size, making the cross-sectional area of the intake filter along the direction perpendicular to the air duct relatively small. After hair accumulates on the upstream surface of the intake filter, it is likely to block the intake filter and cut off the air duct. Therefore, in this embodiment, a thin plate 147 with small holes can be provided upstream of the intake filter 143. At least a part of the periphery of the thin plate 147 is hermetically connected to the inner wall of the air duct 14. There is a gap 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 blower 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, so that the air in the inhaled air flow can flow through the holes in the thin plate 147 to the intake filter 143, and the floating hairs entrained in the air flow can be intercepted by the small holes in the thin plate 147.

[0054] The floating hairs in the air flow can be intercepted by the mesh holes in the thin plate 147. The dust that may be carried in the air flow can penetrate the mesh holes but can be intercepted by the intake filter 143. The thin plate 147 and the mesh holes can extend from the intake filter 143 all the way to the air duct inlet, which is equivalent to increasing the area of the intake filter to accommodate more floating hairs in the accommodation cavity 142.

[0055] The thin plate 147 with small holes can be rectangular or arc-shaped. It can be a small piece, or two small pieces or multiple small pieces, and can also cover the inner wall of the air duct 14.

[0056] In addition, Figure 8 In [description], the thin plate 147 is provided by hermetically connecting the whole 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 hermetically connected to the inner wall of the air duct 14, and the rear part of the periphery of the thin plate 147 is integrated with the intake filter 143.

[0057] Since it is a rechargeable pet grooming machine, as long as the battery has sufficient power, the user can groom the kitten at any time and any place without forcing the kitten to move near the pet grooming machine. Instead, the user can hold the pet grooming machine 100 close to the location where the kitten is, even in a moving state during a journey, such as in a moving car, and can groom the kitten's hair and suck the floating hairs into the accommodation cavity.

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

[0059] Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
