Description

Technical Field

[0001] This invention relates to the field of pet toilet deodorization technology, specifically a floor-standing pet toilet deodorization device. Background Technology

[0002] With the acceleration of urbanization and the improvement of people's living standards, more and more families are choosing to keep pets. However, the problem of pets defecating everywhere at home has brought a lot of trouble to pet owners, especially the odor produced by pet excrement, which seriously affects the hygiene and air quality of the home environment and brings a large cleaning burden to pet owners.

[0003] In existing technologies, the following methods are mainly used to solve the odor problem of pet toilets: First, adding deodorizing granules or powder to the cat litter. However, this method has limited deodorizing effect and requires frequent replenishment as the cat litter is changed. Second, using manual deodorizing spray. Pet owners need to manually spray the deodorizer after their pets defecate. This operation is cumbersome and easy to forget. It is also impossible to watch over the pets 24 hours a day to spray it in time when they defecate. Third, some automated pet toilets have built-in flushing devices that can wash away excrement. However, such devices are complex in structure, expensive, bulky, and not easy to move.

[0004] According to invention patent CN216337178U, a pet toilet deodorizing device is disclosed, including a liquid storage tank, a nozzle, a sensor probe, and a control component. The device controls the nozzle to spray deodorizing liquid when the sensor probe detects that a pet has left. However, the nozzle's installation position and angle are fixed, making it impossible to flexibly adjust the spray coverage according to the actual size and shape of the pet toilet, resulting in poor adaptability. Furthermore, the device lacks a delayed spray function; spraying immediately after the pet leaves can easily spray deodorant onto the pet, causing discomfort. Additionally, the pre-filled liquid storage tank is pressurized, posing a significant risk and potentially causing unnecessary harm to the pet.

[0005] Therefore, how to provide a fully automatic pet deodorizing device that is flexible in installation location, highly adaptable, can effectively cover pet toilets of different sizes and shapes, and avoids deodorizing agent spraying onto pets is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to provide a floor-standing pet toilet deodorization device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a floor-standing pet toilet deodorizing device, comprising a housing, a deodorant storage bottle disposed in a groove on the top left side of the housing, a one-way valve installed on the water outlet at the bottom of the deodorant storage bottle, a fixing shell disposed in a groove on the top right side of the housing, a water pump disposed on the inner wall of the fixing shell, a water inlet at the bottom of the water pump being connected to a pipe on the one-way valve via a silicone water delivery hose, a water outlet pipe connected to the water outlet at the top of the water pump, a universal tube disposed on the top of the fixing shell, and a fan-shaped atomizing nozzle assembly connected to the universal tube.

[0008] Optionally, a sensing probe is installed at the bottom of the front side of the inner wall of the fixed housing. The front side of the sensing probe penetrates the fixed housing and extends to its exterior. The sensing probe includes at least one of an infrared sensor, a human body sensor, and a radar sensor switch.

[0009] Optionally, a control component is provided on the inner wall of the fixed shell, and the control component is electrically connected to the sensing probe and the water pump respectively.

[0010] Optionally, the control component includes a delay module, a spray count control module, and a spray duration control module. A charging power interface is installed on the back of the fixed shell, and a lithium battery is installed on the inner wall of the fixed shell at the position corresponding to the charging power interface. The lithium battery is electrically connected to the water pump, the sensing probe, and the control component.

[0011] Optionally, a touch switch is installed on the top of the back side of the inner wall of the fixed housing, the back of the touch switch penetrates through the fixed housing and extends to its outside, and several anti-slip pads are pasted and installed on the bottom of the housing.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] 1. The combination design of the universal tube and the fan-shaped atomizing nozzle assembly of this invention allows for flexible adjustment of the spray angle and direction. The fan-shaped spray angle covers a continuous range from 1 degree to 90 degrees. Combined with the universal tube's ability to adjust to any direction and angle, regardless of whether the pet toilet is square, round, or irregular in shape, or small or large in size, the optimal placement position and spray coverage can be found through flexible adjustment. This achieves comprehensive coverage of the pet toilet's excretion area by the atomized deodorizer, making it highly adaptable.

[0014] 2. By setting up a sensing probe, the present invention enables infrared sensors, human body sensors, and radar sensing switches to be flexibly configured or combined according to different usage environments and needs, ensuring sensitive and reliable sensing and accurate identification of the pet's entry and exit status.

[0015] 3. This invention features an intelligent delayed spray function. After the pet leaves the pet toilet, the control component activates the spray after a preset delay. This ensures that deodorization is performed in real time after the pet finishes using the toilet, while effectively preventing the deodorant from spraying onto the pet and causing discomfort, thus improving the user experience.

[0016] 4. The adjustable spray frequency and duration of this invention allow users to flexibly set spray parameters according to the size of the pet toilet, the degree of odor, and the concentration of deodorant. This ensures deodorization while avoiding deodorant accumulation or excessive consumption, achieving a balance between energy conservation, environmental protection, and efficient deodorization. It also enables automated, intelligent, and efficient deodorization of pet toilets, solving technical problems such as poor adaptability, easy spraying on pets, and limited spray range in existing technologies. It has significant practical value and market promotion prospects.

[0017] 5. By setting a one-way valve, this invention facilitates users in replacing the deodorant while effectively preventing leakage risks during transportation and storage, thus improving product safety and ease of use. Moreover, the floor-standing design with anti-slip pads at the bottom makes it easy to move and place. Users do not need to install or modify their existing pet toilets; it is ready to use immediately, saving time and effort. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1

[0031] Please see Figure 1-10The floor-standing pet toilet deodorizing device includes a housing 1 made of environmentally friendly resin. Six anti-slip pads 15, made of thickened nitrile rubber, are attached to the bottom of the housing 1 to increase ground friction and ensure the housing 1 is stable and does not slide when placed near the pet toilet. A deodorant storage bottle 2, made of transparent material, is placed in a recess on the top left side of the housing 1 for easy observation of the remaining deodorant level. A one-way valve 3, with a nitrile rubber valve core and POM valve seat, prevents liquid from flowing out when the deodorant storage bottle 2 is inverted and not attached to the housing 1, facilitating easy replacement and replenishment of the deodorant and preventing leakage during transportation or storage. A fixing shell 4 and a protrusion 3 are installed in a recess on the top right side of the housing 1. 1. A groove 32 is provided at the bottom of the fixed shell 4 corresponding to the position of the protrusion 31. The fixed shell 4 is inserted into the groove, and the protrusion 31 is inserted into the groove 32, which achieves a preliminary positioning effect. An I-shaped bracket 30 is provided on the inner wall of the fixed shell 4. The fixed shell 4 is made of 304 stainless steel. A T-shaped screw 24 is provided at the bottom of the inner wall of the fixed shell 4. The bottom end of the T-shaped screw 24 passes through the I-shaped bracket 30, the fixed shell 4 and the placement shell 1 from top to bottom and extends into the interior of the placement shell 1. Two sets of flat washers 25 and a second spring washer 26 are respectively fitted on the surface of the T-shaped screw 24. The surface of the T-shaped screw 24 is locked and fixed by two locking nuts 27. The top of the fixed shell 4 is threadedly connected to the pipe cap 21. The I-shaped bracket 30 is equipped with a water pump 5. The water pump 5 is a miniature diaphragm water pump or a miniature peristaltic water pump, which has the advantages of low noise, stable flow and low power consumption. The water inlet at the bottom of the water pump 5 is connected to the pipe on the one-way valve 3 through the silicone water delivery hose 6 and the pipe through the pagoda head.

[0032] A water outlet pipe 7, made of rubber tubing, is installed on the outlet of the top of the water pump 5. A quick-connect fitting 20 is installed on the top of the pipe cover 21, and a universal joint 8, connected to the quick-connect fitting 20, is inserted into it. To remove the universal joint 8, simply press the top of the quick-connect fitting 20 to pull it out. The bottom end of the quick-connect fitting 20 passes through the pipe cover 21 and the I-beam bracket 30 and extends to their exterior. A first spring washer 21 is fitted onto the surface of the quick-connect fitting 20, and a long nut 22 is threaded onto the surface of the quick-connect fitting 20 and located at the bottom of the first spring washer 21. The elasticity of the first spring washer 21 is utilized to... This ensures a very secure lock, preventing loosening due to external forces. The inner wall of the long nut 22 is threaded to connect to a pagoda connector 23. The top of the water outlet pipe 7 passes through the pagoda connector 23 and extends into it. Utilizing the inherent elasticity of the water outlet pipe 7, it tightly grips the pagoda connector to achieve a sealing effect. The universal tube 8 uses a flexible metal inner core wrapped in soft rubber, allowing it to bend and retain its shape independently, enabling free adjustment in any direction and angle. The universal tube 8 is connected to a fan-shaped atomizing nozzle assembly 9 via a quick connector 16. The fan-shaped atomizing nozzle assembly 9 consists of an atomizing nozzle connecting rod 17, an O-ring 18, and an atomizing nozzle 19. The O-ring 18 is fitted onto the atomizing nozzle 19, and atomization is achieved through... The nozzle 19 and the atomizing nozzle connecting rod 17 are connected by threads and tightened to form the fan-shaped atomizing nozzle assembly 9, achieving a leak-proof effect. The fan-shaped atomizing nozzle assembly 9 and the universal tube 8 are inserted into the holes at both ends of the quick connector 16 to form a single unit. To remove, press the two ends of the quick connector 16 to remove the corresponding parts. The fan-shaped atomizing nozzle assembly 9 can be selected with or without angle adjustment. The fan-shaped atomizing nozzle assembly 9 is made of wear-resistant POM plastic. The angle-adjustable fan-shaped atomizing nozzle assembly 9 has an integrally formed rotating adjustment ring on the outer ring. The spray adjustment angle of the fan-shaped atomizing nozzle assembly 9 is 1-90°, which users can adjust according to the actual needs of their pet toilet. The size and shape of the spray nozzles can be adjusted by rotating or toggling the adjustment ring on the nozzle head to change the angle of the fan-shaped spray. For small pet toilets, the spray can be adjusted to a small angle for concentrated spraying, while for large pet toilets, the spray can be adjusted to a wide angle for wide spraying, achieving the best coverage effect. The combination design of the universal tube 8 and the fan-shaped atomizing nozzle assembly 9 allows for flexible adjustment to find the best placement position and spray angle regardless of the size or shape of the pet toilet, ensuring that the spray can fully cover the excretion area inside the pet toilet. This compensates for the problem of incomplete coverage of pet toilets of different sizes and shapes. For those that cannot be adjusted in angle, the outer ring does not have an integrated rotating adjustment ring, and the spray angle is fixed.

[0033] A sensor probe 10 is installed at the bottom of the front side of the inner wall of the fixed housing 4. The sensor probe 10 consists of a sensor head circuit board 28 and a sensor head cover 29. The sensor head cover 29 passes through the fixed housing 4 and is fixedly connected to the inner wall of the fixed housing 4. The end of the sensor head circuit board 28 near the sensor head cover 29 passes through the sensor head cover 29 and extends into it and is fixedly connected to it. The sensor probe 10 is used to sense the entry and exit status of pets in the pet toilet. The front side of the sensor probe 10 passes through the fixed housing 4 and extends to its outside. The sensor head circuit board 28 is equipped with at least one of an infrared sensor, a human body sensor, and a radar sensor switch. A single sensor or a combination of multiple sensors can be selected according to the usage environment and user needs. The infrared sensor detects the presence of pets by detecting changes in infrared signals and is suitable for open pet toilets. The radar sensor switch determines whether the pet is within the sensing range by emitting and receiving microwave signals and has the advantage of not being affected by ambient temperature and light. The human body sensor, such as a pyroelectric infrared sensor, is suitable for detection scenarios that are sensitive to temperature changes. The selection and combination design of multiple sensor probes 10 ensures sensitive and reliable sensing and avoids false triggering or missed triggering.

[0034] A control component 11 is installed on the inner wall of the fixed shell 4. The control component 11 is electrically connected to the sensor probe 10 and the water pump 5. When the sensor probe 10 detects that the pet has left the pet toilet, the control component 11 controls the water pump 5 to start, delivering the deodorant in the deodorant storage bottle 2 through the silicone water delivery hose 6, the water outlet pipe 7, and the universal pipe 8 to the fan-shaped atomizing nozzle assembly 9 for atomization and spraying. The control component 11 is a single-chip microcomputer control circuit, integrating a delay module, a spray count control module, and a spray duration control module. The delay module delays the start of the water pump 5 by 1 second to 10 minutes after the sensor probe 10 detects that the pet has left the pet toilet, ensuring that the deodorant is delivered from the storage bottle 2 and then atomized and sprayed. Spraying should only begin after the pet has completely left the litter box, effectively preventing deodorant from getting on the pet and ensuring their health and comfort. The spray frequency control module allows for adjustment of the spray frequency from 1 to 10 times. By setting the appropriate spray frequency, deodorant buildup in the litter box can be avoided due to excessive spraying, keeping the litter box dry and usable. The spray duration control module allows for adjustment of the spray duration from 0.1 seconds to 600 seconds. This adjustable spray duration design allows users to flexibly control the amount of deodorant sprayed based on factors such as the size of the litter box and the intensity of odor, avoiding buildup or waste of deodorant due to excessive spraying time.

[0035] A charging power interface 12 is fastened to the back of the fixed shell 4 by an outer rib. A lithium battery 13 is installed on the I-shaped bracket 30. The lithium battery 13 is a 3.7V-18650 ternary rechargeable lithium battery. The lithium battery 13, in conjunction with the working mode of the water pump 5, can achieve long-lasting use. Users can conveniently charge it through the charging power interface 12. The lithium battery 13 is electrically connected to the water pump 5, the sensing probe 10 and the control component 11 respectively. A touch switch 14 is fastened to the top of the back of the inner wall of the fixed shell 4 by an outer rib. The back of the touch switch 14 penetrates through the fixed shell 4 and extends to its outside. Press and hold for 3 seconds to turn on the power, and press and hold again for 3 seconds to turn off the power.

[0036] When in use, pull up to remove the deodorant storage bottle 2, add deodorant, and then re-insert it into the groove of the housing 1. The pipeline will automatically connect to the one-way valve 3. Place the housing 1 in a suitable position near the pet toilet, adjust the direction and angle of the universal tube 8 so that the fan-shaped atomizing nozzle assembly 9 is aimed at the excretion area of ​​the pet toilet, and then adjust the fan-shaped angle of the fan-shaped atomizing nozzle assembly 9 so that the spray range can fully cover the excretion area of ​​the pet toilet.

[0037] The device enters standby mode, and the sensor 10 continuously monitors the entry and exit of pets in the pet toilet. When a pet enters the pet toilet, the sensor 10 detects the pet's presence and begins to prepare for response. After the pet finishes using the toilet and leaves, the sensor 10 detects the pet's departure signal and transmits it to the control component 11. The control component 11 starts a delay timer according to a preset delay time to ensure that the pet has completely left the pet toilet before starting the spray, avoiding spraying deodorant onto the pet. After the delay ends, the control component 11 controls the water pump 5 to start according to the preset number of sprays and the duration of each spray. The water pump 5 draws deodorant from the deodorant storage bottle 2 through the silicone water delivery hose 6, and delivers it to the fan-shaped atomizing nozzle assembly 9 through the water outlet pipe 7 and the universal pipe 8. The deodorant is sprayed out at a preset fan-shaped angle to quickly deodorize the excrement in the pet toilet. After the spraying ends, the device automatically returns to standby mode, waiting for the next trigger.

[0038] Example 2

[0039] The difference between this embodiment and embodiment 1 is that the control component 11 also includes a learning and memory module. When the device is used for the first time, after the user completes a complete spray deodorization operation in manual mode, the learning and memory module automatically records the delay time, number of sprays and spray duration parameters of the operation, and executes the spray program according to the parameters recorded for the first time in subsequent automatic operations, realizing one-click setting and further simplifying user operation.

[0040] Example 3

[0041] The difference between this embodiment and embodiment 1 is that the circuit board 28 of the sensing head is equipped with an infrared sensor and a radar sensing switch. The control component 11 performs logic AND judgment on the sensing signals of the two sensors, and only triggers the spray when both sensors detect that the pet has left. This can effectively reduce the probability of false triggering by a single sensor and improve the working reliability of the device.

[0042] Example 4

[0043] The difference between this embodiment and embodiment 1 is that the deodorant storage bottle 2 has a capacity of 200-1000ml, is made of transparent material and is integrally injection molded, which makes it convenient for users to add deodorant and clean it regularly. The deodorant storage bottle 2 is connected to the housing 1 by a snap-on quick-release structure, which is convenient to disassemble and install, and is easy for users to remove for cleaning or replacement.

[0044] When a pet enters the infrared (human body sensor, radar) detection range and remains there for more than 1-600 seconds, and then leaves for 1-600 seconds, the machine will spray (deodorant) 1-20 times, each spray lasting 0.1-120 seconds, followed by a 0.1-600 second pause. If the pet passes through the infrared (human body sensor, radar) detection range again within 1-600 seconds, the machine will spray 1-20 times, each spray lasting 0.1-120 seconds, followed by a 0.1-600 second pause.
