Description

Technical Field

[0001] This invention belongs to the field of household goods technology, and in particular relates to a pet vacuum cleaner hair collector. Background Technology

[0002] Pet hair, especially animal hair, is difficult to clean thoroughly with ordinary cleaning tools due to its long, thin, and lightweight nature. In particular, after pet grooming, multiple cleaning and collection processes of the trimmed hair are required, making the process time-consuming.

[0003] To address this issue, Chinese Patent 202220526155.9 discloses a technical solution for a pet hair dryer entitled "A Hair Collection Device for a Pet Hair Dryer." This solution can quickly clean up animal hair, but it has the following drawbacks: Because the filter cover and air inlet are parallel, hair and air entering the collection box through the air inlet do not swirl within the box. Instead, the hair is directly filtered and separated from the air by the filter cover, and the hair is collected in the collection box. During this process, hair easily clogs the filter cover, preventing further hair collection. However, at this point, the hair content collected in the collection box is only 50% of its capacity, significantly reducing the volume utilization rate of the collection box.

[0004] Therefore, designing a pet vacuum cleaner hair collector that improves the utilization rate of the collection box volume is an important technical problem that those skilled in the art need to solve. Summary of the Invention

[0005] The purpose of this invention is to solve the above-mentioned problems existing in the prior art and to provide a pet vacuum cleaner hair collector.

[0006] The objective of this invention is achieved through the following technical solution: A pet vacuum cleaner hair collector includes a main unit and a collection box detachably mounted on the main unit. The main unit is an exhaust device with a motor and blades driven to rotate inside. The air inlet of the main unit communicates with the internal space of the collection box. The collection box includes at least a first filter and a second filter perpendicular to the first filter. The first filter is located on the end face of the collection box near the main unit. Air from the internal space of the collection box is filtered by the first filter and enters the negative pressure area formed by the main unit, forming a first air duct. The second filter is located at the bottom of the collection box. Air from the internal space of the collection box is filtered by the second filter and enters the negative pressure area formed by the main unit through the second air duct.

[0007] Preferably, the first air duct is located between the first filter and the blade, and the second air duct is located on the base plate of the main unit.

[0008] Preferably, the second air duct comprises two parts: the first part is the gap between the bottom of the collection box and the upper surface of the base plate of the host, and the second part is a guide channel communicating with the gap.

[0009] Preferably, the guide channel is a 90° tube with a rounded transition.

[0010] Preferably, the bottom of the collection box is pivotally connected to its inner end face; the bottom of the collection box is provided with a collection box inlet communicating with the air inlet, and the central axis of the collection box inlet is perpendicular to the axis of the main motor.

[0011] Preferably, the air inside the collection box is split when it enters the first filter and the second filter respectively, and the swirling of the airflow after they come into contact with each other makes it difficult for hair and dust to accumulate on the first filter.

[0012] Preferably, the collection box is connected to the host via a snap-fit ​​structure; the snap-fit ​​structure includes at least a first snap-fit ​​block and a first snap-fit ​​slot; the first snap-fit ​​block is located at one end of the second air duct and close to the first air duct, the first snap-fit ​​slot is located at one end of the second filter screen and close to the first filter screen, and the position of the first snap-fit ​​slot corresponds to and matches that of the first snap-fit ​​block.

[0013] Preferably, the snap-fit ​​structure further includes a second snap-fit ​​block and a second snap-fit ​​slot; the second snap-fit ​​block is disposed above the first air duct, and the second snap-fit ​​slot is disposed above the first filter screen, and corresponds to and matches the position of the second snap-fit ​​block; the host is also provided with a locking key for controlling the second snap-fit ​​block to move in the vertical direction.

[0014] Preferably, the outer casing of the main unit is also provided with an adjustment button for adjusting the suction strength.

[0015] Preferably, the main unit is also provided with a handle, which is pivotally located on both sides of the main unit.

[0016] The advantages of the technical solution of this invention are mainly reflected in: The air inlet is not positioned opposite to the first air duct and the first filter. Dust and pet hair will swirl inside the collection box and will not be directly adsorbed onto the first filter, thus making the first filter less prone to clogging. Through the mutual convection of the first and second air ducts, animal hair and dust are less likely to clog the first and second filters. Ultimately, the animal hair and dust will stay in the area without air convection and then gradually gather at the air inlet and outlet, effectively delaying the clogging time of the first and / or second filters and increasing the volume utilization rate of the collection box. The collection box and the main unit are detachably connected by a snap-fit ​​structure, and the connection is reinforced by a locking key on the main unit to ensure the stability of both after installation. At the same time, the collection box can be quickly disassembled for easy cleaning or replacement. The operation is simple and convenient. Attached Figure Description

Detailed Implementation

[0018] The objectives, advantages, and features of this invention will be illustrated and explained through the following non-limiting description of preferred embodiments. These embodiments are merely typical examples of applying the technical solutions of this invention, and all technical solutions formed by equivalent substitutions or equivalent transformations fall within the scope of protection claimed by this invention.

[0019] In the description of the solution, it should be noted that the terms "center," "upper," "lower," "left," "right," "front," "rear," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience and simplification of description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Also, in the description of the solution, with the operator as a reference, the direction closer to the operator is the proximal end, and the direction farther from the operator is the distal end.

[0020] This invention discloses a pet vacuum cleaner hair collector, comprising, as follows: Figure 1 The diagram shows a main unit 1 and a collection box 2 detachably mounted on the main unit 1. The main unit 1 is an exhaust device, internally equipped with a motor and blades driven to rotate by the motor. Since the structure and connection relationship of the motor and blades are known prior art, they will not be described in detail here. Figures 1 to 3As shown, the outer casing of the host 1 is provided with at least one power button 111 that is electrically connected to the motor and drives the motor to start and stop.

[0021] like Figure 2 , Figure 3 As shown, the collection box 2 includes a first filter screen 21. Preferably, the first filter screen 21 is made of metal mesh, but the material can be adjusted according to usage requirements; therefore, the material is not limited here. The first filter screen 21 is disposed on the inner end face of the collection box 2 (the end face of the collection box 2 closest to the main unit 1) and close to the main unit 1. A first air duct 11 is disposed on the main unit 1 near the collection box 2. The first air duct 11 is located between the first filter screen 21 and the blades.

[0022] The main unit 1 and the collection box 2 are connected by an air inlet 102. The outlet direction of the air inlet 102 is perpendicular to its setting direction and is located at the bottom of the collection box 2 and close to the outer end face of the collection box 2 (the end face of the collection box 2 away from the main unit 1). The bottom of the collection box 2 is provided with a collection box inlet 20 that communicates with the outlet of the air inlet 102.

[0023] After the main unit 1 is started, it will draw air from the collection box 2 and the air inlet 102, thereby making the air pressure P1 inside the main unit 1 lower than the air pressure P2 inside the collection box 2, and lower than the air pressure P3 outside the air inlet 102. Therefore, animal hair and air on the ground will enter the collection box 2 through the air inlet 102; that is, the main unit 1 drives the hair and air to enter the collection box 2 through the air inlet 102. Finally, the air filtered by the first filter screen 21 will enter the main unit 1 through the first air duct 11 and then be discharged to the outside of the main unit 1.

[0024] Since the air inlet 102 is not opposite to the first air duct 11 and the first filter 21, the air and animal hair will swirl after entering the collection box 2, that is, the animal hair will not be directly adsorbed onto the first filter 21, thus making the first filter 21 less likely to be blocked.

[0025] Furthermore, such as Figure 2As shown, the collection box 2 also includes a second filter 22, which is the same as the first filter 21. Preferably, the second filter 22 is made of metal mesh, but the material can be adjusted according to usage requirements; therefore, the material is not limited here. The second filter 22 is located at the bottom of the collection box 2 and on one side of the outlet of the air inlet 102; that is, the second filter 22 is perpendicular to the direction of the first filter 21. A second air duct 12 is also provided on the main unit 1 near the collection box 2. The second air duct 12 includes two parts: the first part is the gap between the bottom of the collection box 2 and the upper surface of the base plate of the main unit 1; the second part is a guide channel 13 communicating with the gap. The guide channel 13 is a 90° pipe with a rounded transition. Multiple pipes can be arranged side-by-side, or a single pipe can be used, serving to connect the negative pressure area of ​​the main unit. Finally, the air filtered by the second filter 22 will enter the main unit 1 through the second air duct 12 and then be discharged to the outside of the main unit 1.

[0026] By adding the second filter 22, the air inside the collection box is diverted when it enters the first and second filters respectively. Furthermore, the swirling airflow after contact prevents hair and dust from easily accumulating on the first filter. Therefore, after starting the main unit 1, the animal hair, air, and dust entering the collection box 2 are prevented from easily clogging the first and second filters 21 and 22 due to the mutual convection between the first and second air ducts 11 and 12. Ultimately, the animal hair and dust will remain in areas without air convection and then gradually converge towards the outlet of the air inlet 102. This invention effectively extends the replacement time of the collection box 2 and its internal filter cover, reducing operating costs.

[0027] Through usage verification, more than 95% of the space in the collection box 2 of this collector can be used to collect animal hair and dust, while traditional collectors can only collect about 50% of animal hair and dust. That is, the collector disclosed in this invention can expand the volume utilization rate of the collection box 2.

[0028] Furthermore, the collection box 2 is constructed via, for example... Figure 4 The shown snap-fit ​​structure is connected to the host 1. The snap-fit ​​structure includes at least a first snap-fit ​​block 31 and a first snap-fit ​​slot 32. The number of the first snap-fit ​​block 31 and the first snap-fit ​​slot 32 is not limited to one, but in this invention, two are preferably arranged symmetrically along the axis of symmetry of the host 1.

[0029] like Figure 3As shown, the first locking block 31 is disposed at one end of the second air duct 12 and close to the first air duct 11, that is, the first locking block 31 is disposed at the corner of the second air duct 12 and the first air duct 11. Figure 4 As shown, the first slot 32 is located at one end of the second filter screen 22 and close to the first filter screen 21, that is, the first slot 32 is located at the corner of the second filter screen 22 and the filter cover 21, and the first slot 32 corresponds to and matches the first locking block 31. After the first locking block 31 engages with the first slot 32, the position of the collection box 2 is fixed in the X-axis (length direction of the host 1) and Y-axis (width direction of the host 1) directions of the host 1.

[0030] Furthermore, the snap-fit ​​structure also includes a second snap-fit ​​block 33 and a second snap-fit ​​groove 34. The second snap-fit ​​block 33 is disposed above the first air duct 11, and the second snap-fit ​​groove 34 is disposed above the first filter screen 21, corresponding to and matching the position of the second snap-fit ​​block 33. The number of the second snap-fit ​​block 33 and the second snap-fit ​​groove 34 includes, but is not limited to, one; the present invention preferably provides one, and the second snap-fit ​​block 33 and the second snap-fit ​​groove 34 are respectively centrally disposed above the first air duct 11 and the first filter screen 21. Based on the snap-fit ​​of the first snap-fit ​​block 31 and the first snap-fit ​​groove 32, the second snap-fit ​​block 33 and the second snap-fit ​​groove 34 are then snap-fitted together, fixing the position of the collection box 2 in the Y-axis direction (height direction of the main unit 1) of the main unit 1, ensuring that the collection box 2 will not easily fall off after being snapped together with the main unit 1, thus ensuring the stability of the installation.

[0031] like Figure 1 As shown, the host 1 is also equipped with a locking key 112 for controlling the vertical movement of the second locking block 33. Specifically, when a force is applied to the locking key 112 manually or by external force, the second locking block 33 connected to the locking key 112 will move synchronously, thereby disengaging the second locking block 33 from the second slot 34, so as to facilitate the removal of the collection box 2 from the host 1 and to facilitate the cleaning or replacement of the collection box 2.

[0032] like Figure 3 As shown, the bottom of the collection box 2 is pivotally connected to its inner end face (i.e., the end face where the first filter screen 21 is located) to facilitate the disassembly and replacement of the second filter screen 22 of the collection box 2.

[0033] The main unit 1 is also equipped with an adjustment button 113 for adjusting the suction power, and handles 114 pivotally mounted on both sides of the main unit 1. The handles 114 facilitate the movement or carrying of the main unit 1 or the pet vacuum cleaner hair collector, improving ease of use.

[0034] This invention has many other embodiments. It should be noted that the preferred embodiment of this invention discloses a method of diverting airflow through a first filter and a second filter, thereby preventing hair and dust from accumulating too quickly. Under this principle, all technical solutions formed by using equivalent transformations or similar modifications, such as the arrangement of multiple filters or different positions of two filters, fall within the protection scope of this invention.
