Description

Technical Field

[0001] This utility model relates to the field of air purification technology, specifically to a spray device, a device connection structure, and a purifier with a spray device. Background Technology

[0002] As living standards improve, people are paying more and more attention to the quality of their home environment. In particular, families with pets are increasingly in need of air purification equipment. Traditional air purifiers can effectively filter pet hair, dust and some odors in the air, but their functions are relatively simple. In order to improve the user experience, air purifiers with integrated spray humidification or aromatherapy functions have appeared on the market. They can humidify the air or spray a mist while purifying it.

[0003] However, these existing all-in-one designs have obvious shortcomings. Their atomizing devices are usually fixedly connected to the air purifier main unit or built into the body, making it impossible for users to easily remove the atomizing device. This non-removable structure brings many problems. For example, it is difficult for users to thoroughly clean the liquid tank, flow channel and spray component of the atomizing device. Long-term use can easily lead to bacterial growth or blockage. If the user does not need the spraying function temporarily, the fixed device cannot be removed, which destroys the overall integrity and simplicity of the appearance. The all-in-one design also limits the flexibility of function. For example, it is not easy to change different types of spray liquid according to needs.

[0004] Therefore, existing air purifiers with atomization functions need improvement in terms of ease of use, convenience of cleaning and maintenance, and flexibility of function combinations. There is an urgent need for a new solution that can provide users with a freely detachable, easy-to-maintain, and intelligently controlled external spray module while retaining the core air purification function. Summary of the Invention

[0005] The purpose of this utility model is to provide a spraying device, a device connection structure, and a purifier with a spraying device as technical solutions to solve the problems raised in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a spraying device, comprising at least one liquid tank and a spraying component, wherein the spraying component is provided with a liquid inlet, a gas inlet and at least one atomization outlet. The liquid tank is connected to the liquid inlet via a liquid inlet head, and the gas inlet is connected to a diaphragm pump. Under the negative pressure of the diaphragm pump, the liquid in the liquid tank flows along the liquid inlet head to the atomization outlet. By setting up liquid and gas channels, mixing and blockage between the two can be avoided, ensuring smooth liquid delivery and atomization process. The liquid flow is driven by the negative pressure of the diaphragm pump, eliminating the need for additional manual pressurization, resulting in a high degree of automation. Furthermore, the negative pressure delivery can precisely control the liquid flow rate, ensuring stable atomization effect.

[0007] The spraying device also includes a front shell and a rear shell, which together form a receiving cavity. The receiving cavity is provided with a fixing slot, which is used to fix the spraying component, liquid tank, diaphragm pump and liquid inlet head. The receiving cavity provides a unified protective space for all components, isolating them from external dust and moisture, extending the service life of the components. The fixing slot accurately positions the spraying component, liquid tank and other components, avoiding loosening of connections caused by shaking or collision, improving the overall structural stability, and simplifying the assembly process.

[0008] A hole is provided on one side of the front or rear shell, and the atomization outlet sprays through the hole. The hole provides a directional spray channel for the atomization outlet, preventing the atomized gas from spreading randomly and ensuring that the spray direction is controllable. The hole can also cover internal components, improve the appearance of the device, and prevent foreign objects from entering the interior through the spray port.

[0009] The spraying device also includes an atomizing start plate for controlling the start and stop of the diaphragm pump. The atomizing start plate is installed in a fixed slot. The atomizing start plate can realize the automatic control of the diaphragm pump, which makes it convenient for users to start and stop the spraying function as needed, save energy, and ensure that the start plate is stable in position by being installed in the fixed slot, avoiding vibration that could cause poor circuit contact and ensuring reliable control function.

[0010] A connection structure includes a contact bracket and a contact adapter plate. The contact adapter plate is provided with contact pins, the pins extending into the contact bracket. When a spray device is inserted into the contact bracket, the pins extend into the spray device and are electrically connected to an atomizing start plate. The contact-type connection eliminates the need for complex wiring, enabling quick assembly and disassembly of the spray device and the air purifier, improving ease of use. The electrical connection between the pins and the start plate ensures stable conductivity, avoiding the problem of loosening in traditional plugs and ensuring smooth circuit operation.

[0011] The contact bracket is a closed or semi-closed structure formed by thin plates. The bottom of the contact bracket is provided with a platform for supporting the spraying device. The closed or semi-closed structure provides lateral restraint for the spraying device to prevent it from swaying left and right after insertion. The bottom support platform provides stable support for the spraying device to avoid sinking or poor contact due to gravity, thereby enhancing installation reliability.

[0012] The contact bracket has through holes, through which the contact pins extend into the contact bracket. The through holes provide a precise installation path for the contact pins, ensuring that the pins are fixed in position and making the connection between the contact pins and the spray device more precise and stable. The pins extend through the through holes to avoid being exposed to the outside and damaged by collisions, thus extending the service life of the connection structure.

[0013] An air purifier includes a body, with a connecting structure installed on the side wall of the body. The side mounting facilitates the insertion of a spray device without occupying top or bottom space, thus saving overall layout space. An adapter plate serves as a connection interface, allowing the spray device to be modularly mounted externally, expanding the spray function without affecting the original structure of the air purifier.

[0014] The unit has a columnar structure that is narrower at the top and wider at the bottom. Air outlets and inlets are located at the top and bottom of the unit, respectively. A top cover is provided on the top, and a circular base is located at the bottom. The narrower-than-wider structure lowers the center of gravity, and the circular base increases the contact area, improving the stability of the purifier. This is especially suitable for scenarios where pets are present, reducing the risk of tipping over. The circular base has no sharp edges, preventing pets from colliding and getting injured, enhancing safety. The top outlet and bottom inlet create a vertical airflow circulation, conforming to air convection principles and improving purification efficiency. The top cover prevents dirt from falling into the air outlet.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. Easy to disassemble and clean: This structure, through its external spray structure and contact connection design, enables quick disassembly and assembly of the spray device. Users can easily disassemble it for cleaning or replacement, avoiding the inconvenience of cleaning traditional integrated structures and improving ease of use and maintainability. 2. Flexible Function Expansion: When the spray function is not in use, the appearance remains intact and the main function of the air purifier is not affected. The external spray device achieves circuit and signal transmission through contact connection, which is highly expandable and the spray module can be flexibly added or removed as needed. 3. Enhanced deodorization and sterilization effects: This structure supports the spraying of liquids such as probiotics, which are diffused into the air through atomization, effectively decomposing odors and inhibiting bacteria. It is suitable for pet-friendly households and enhances the deodorization and health protection functions of air purifiers. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: This embodiment provides a spraying device.

[0020] like Figure 1 As shown, the spray device 2 includes a liquid tank 25, a liquid inlet head 21, a diaphragm pump 23, a spray element 22, an atomization start plate 27, a front shell 24, and a rear shell 26.

[0021] The front shell 24 and the rear shell 26 enclose a receiving cavity, and a fixing slot 28 is provided inside the receiving cavity. The fixing slot 28 is used to fix the spraying component 22, the liquid tank 25 and the liquid inlet head 21, the diaphragm pump 23 and the atomizing start plate 27. This structure provides a stable, orderly and non-interfering fixing space for all core components.

[0022] The rear shell 26 and the front shell 24 are respectively provided with guide posts and guide grooves. The front shell 24 and the rear shell 26 are fixedly connected by the cooperation of the guide posts and guide grooves.

[0023] like Figure 2 As shown, the liquid tank 25 is fixed to the top of the fixing slot 28 and connected to the spray component 22 through the liquid flow channel 41. It is used to store probiotic liquid. The liquid inlet head 21 is connected to the bottom of the liquid tank 25 to draw out the liquid in the liquid tank 25. The liquid tank 25 can also be removed after use to facilitate the addition of probiotic liquid or other sprays. This structure is convenient and flexible to use.

[0024] The diaphragm pump 23 is installed in the lower half of the fixed slot 28 and is connected to the spray element 22 through the gas flow channel 42. After the diaphragm pump 23 is powered on, the liquid in the liquid tank 25 is drawn out and pressurized and delivered to the spray element 22 under the negative pressure of the diaphragm pump 23.

[0025] like Figure 3-4 As shown, the spray device 22 includes a liquid inlet 221, a gas inlet 222, and an atomization outlet 223. When the spray device 2 is working, the liquid in the liquid tank 25 flows into the liquid inlet 221 along the liquid flow channel 41, and the gas from the diaphragm pump 23 flows into the gas inlet 222 along the direction of the gas flow channel 42. When the user starts the air purifier 1, the external spray device 2 will quickly establish an electrical connection with the contact adapter plate 32 to achieve power supply. This connection method ensures stable signal transmission and guarantees the stability and consistency of the entire system operation.

[0026] Under the action of the diaphragm pump 23, the liquid and gas are mixed and atomized inside the spray element 22, and then sprayed out from the atomization outlet 223.

[0027] The atomizing outlet 223 is installed on the hole 241 on the side wall of the front shell 24 to facilitate the diffusion of mist. The spraying component 22 can efficiently convert probiotic liquid into mist through gas-liquid mixing atomization design and accelerate the spraying out from the side wall to achieve rapid and uniform diffusion.

[0028] The atomizing start plate 27 is connected to the contact adapter plate 32 and can accurately capture various signals transmitted by the air purifier 1 circuit. Based on these received signals, the atomizing start plate 27 can precisely control the start and stop operation of the diaphragm pump 23, thereby achieving fine control of the spraying process.

[0029] Example 2: This embodiment provides a connection structure that can be used to fix and install the spraying device.

[0030] like Figure 5 As shown, the connection structure 3 connects the spray device 2 and the air purifier 1 together, including the contact bracket 31 and the contact adapter plate 32. This structure can achieve a complete whole without the external spray device 2. When externally attached, only the contact bracket 31 and the spray device 2 need to be added to realize the spray function.

[0031] The contact bracket 31 is a rectangular structure formed by thin plates, and its size is adapted to the spray device 2. The contact bracket 31 is provided with multiple through holes 312 for installation and fixing, which facilitates installation and fixing. The bottom of the contact bracket is provided with a platform 311 to support the spray device, and the spray device is fixed through the platform 311.

[0032] The contact adapter plate 32 is installed on the side of the air purifier 1 to connect the circuit of the air purifier 1 with the circuit of the spray device 2. Several contact pins 321 extend outward from the contact adapter plate 32. The size of the contact pins 321 is adapted to the through hole 312. After the contact pins 321 pass through the through hole 312, they are connected to the atomizing start plate 27 in the spray device 2 to realize the conduction of the circuit and the transmission of the signal.

[0033] Specifically, after the contact pin 321 passes through the through hole 312, a length of 3mm is exposed. The exposed part of the contact pin 321 has an arc-shaped edge and is elastic, which facilitates the insertion of the spray device 2 into the contact bracket 31. When the spray device 2 is inserted into the contact bracket 31, the contact pin 321 rebounds and is electrically connected to the atomizing start plate 27. The contact adapter plate 32 is connected to the control circuit to realize the control of the spray device 2.

[0034] Example 3: This embodiment provides an air purifier, which can fix a spray device to the air purifier through a connecting structure.

[0035] Air purifier 1 is the main body, responsible for the intake, filtration and exhaust of air. The connecting structure 3 is used to realize the circuit connection and signal transmission between the spray device 2 and the main body. The spray device 2 is responsible for generating and spraying probiotic mist to play a role in sterilization and deodorization.

[0036] like Figure 6 As shown, the air purifier 1 includes a body 12 and a top cover 15.

[0037] The body 12 has a columnar structure that is narrow at the top and wide at the bottom. A circular base 13 is provided at the bottom to stably support the entire air purifier 1. An air inlet 14 and an air outlet 11 are respectively opened at the top and bottom of the body 12 for air intake and exhaust. A contact adapter plate 32 is installed on the side of the body 12 for connecting with the spray device 2.

[0038] The top cover 15 is installed on the air outlet 11 at the top of the body 12, serving both aesthetic and protective purposes, and preventing dirt from falling into the air outlet 11.

[0039] During installation, first install the spray device 2, and check whether the liquid tank 25, liquid inlet head 21, diaphragm pump 23, spray component 22 and atomizing start plate 27 are installed in the correct position in the fixing slot 28, and whether the guide posts and guide grooves of the front shell 24 and the rear shell 26 are aligned. After checking, gently press until the front shell 24 and the rear shell 26 are completely closed. If there is no obvious displacement when gently shaken, the installation is complete.

[0040] Fix the contact bracket 31 onto the contact adapter plate 32 on the side of the air purifier 1. Hold the spray device 2 and align the bottom of the spray device 2 with the contact bracket 31, with one side of the atomizing start plate 27 aligned with the contact pin 321. Insert it vertically downwards. When the spray device 2 contacts the platform 311, the contact pin 321 springs back and is electrically connected to the atomizing start plate 27. Check that the atomizing start plate 27 and the contact pin 321 are in complete contact and there is no looseness.

[0041] Add probiotic liquid, rotate counterclockwise to remove the inlet head 21, inject an appropriate amount of probiotic liquid into the liquid tank 25, ensuring the liquid level does not exceed the maximum scale line of the liquid tank 25, reinstall the inlet head 21 into the liquid tank 25, and rotate clockwise to a tight position to ensure no liquid leakage.

[0042] When starting up, connect the power supply to the air purifier 1, press the power switch on the side of the unit 12, and the fan at the air inlet 14 will start running.

[0043] The operating mode, such as automatic mode or spray mode, can be selected via remote control or control panel 12 on the device. After selecting spray mode, the control circuit sends a signal to contact adapter 32 to trigger the spray device 2 to start.

[0044] Observe whether the spraying unit 22 sprays out mist, and at the same time listen to whether the diaphragm pump 23 operates abnormally. Normally, it should be a uniform low-frequency humming sound without any noise.

[0045] When the air purifier 1 is turned on, the air inlet 14 at the bottom of the unit 12 starts working. The fan creates a negative pressure zone, drawing indoor air into the unit 12. The drawn-in air passes through multiple layers of filter components to remove pollutants such as hair, dust, PM2.5 particles, and odor molecules. The filtered clean air is then discharged back into the room through the air outlet 11 at the top of the unit 12, forming an air circulation and continuously improving indoor air quality.

[0046] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
