Description

Technical Field

[0001] This application relates to the field of hookah technology, and in particular to a power supply for electronic hookahs. Background Technology

[0002] Arabian hookah originated in India and is mainly popular in Arab countries, with similar forms also existing in Turkey, Iran, and Central Asia. Traditional hookah devices typically hold tobacco at the top and water at the bottom. To use, burning charcoal is placed above the tobacco; the heat from the charcoal vaporizes the tobacco, forming smoke. This smoke is then filtered through the water layer at the bottom and inhaled through the pipe.

[0003] Currently, electronic hookahs that simulate the inhalation experience of traditional hookahs have appeared on the market. Their working principle is to use an electric current to heat the tobacco material (usually tobacco paste or e-liquid), atomizing it into a nicotine-containing aerosol for users to inhale.

[0004] However, existing electronic hookahs are directly powered by lithium batteries, which can easily lead to battery incompatibility with the main unit, resulting in damage to the main unit or safety risks. At the same time, it is difficult to guarantee that the battery can work safely and continuously during heating and atomization when powered by lithium batteries. Utility Model Content

[0019] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0020] The inventors discovered through analysis of existing technologies that: because existing electronic hookahs typically do not have a corresponding battery detection circuit, it is impossible to determine whether the battery and the host model are compatible, thus leading to safety risks. At the same time, because conventional lithium batteries usually do not have corresponding protection circuits, it is difficult to ensure that the battery can continue to work safely during heating and atomization when powered by lithium batteries.

[0021] Reference Figure 1-10 This application illustrates a power supply for an electronic hookah provided in an embodiment of the present application, comprising: a battery assembly 1, a main control board 2, and a pin assembly 3 for electrically connecting to the host 7 of the electronic hookah; the main control board 2 includes an encryption unit for electrically connecting to the host 7 through the pin assembly 3 and generating encrypted electrical signals; The main control board 2 is electrically connected to the battery assembly 1 and the pin assembly 3 respectively; The power supply current of the battery assembly 1 is transmitted to the host 7 through the main control board 2 and the pin assembly 3 in sequence for power supply; When the encryption unit is powered on, it generates an encryption signal with a preset voltage or current value, and transmits it to the host 7 through the pin assembly 3.

[0022] In the embodiments of this application, addressing the common issue of battery incompatibility between existing electronic hookahs and the host device 7, leading to damage or safety risks, this application provides a solution for battery verification by incorporating an encryption unit in the main control board 2 of the power supply. Specifically, a power supply for an electronic hookah includes: a battery assembly 1, a main control board 2, and a pin assembly 3 for electrical connection to the host device 7 of the electronic hookah. The main control board 2 includes an encryption unit for generating an encrypted electrical signal through the pin assembly 3 and being electrically connected to the host device 7. The main control board 2 is electrically connected to both the battery assembly 1 and the pin assembly 3. The power supply current of the battery assembly 1 is sequentially transmitted to the host device 7 through the main control board 2 and the pin assembly 3. When the encryption unit is powered on, it generates an encrypted electrical signal with a preset voltage or current value and transmits it to the host device 7 through the pin assembly 3. This application uses an encryption unit for battery verification, ensuring that the battery assembly 1 and the host device 7 are compatible, thus guaranteeing safety during use.

[0023] The following will further describe a power source for an electronic hookah in this exemplary embodiment.

[0024] It should be noted that the encryption unit may include a resistor with a specific resistance value. When the encryption unit is powered on, the current or voltage input to the resistor with the specific resistance value will generate a corresponding encryption signal, which will be transmitted to the host 7 through the pin assembly 3.

[0025] When the encrypted electrical signal received by the host 7 does not match the pre-stored voltage or current value, an alarm can be issued or the power supply current of the battery assembly 1 can be cut off through the switching unit, thereby preventing damage to the host 7 by a mismatched battery or a faulty third-party battery.

[0026] The power supply described in this application can support up to 30W of full-protocol charging / discharging, and supports PD and QC protocols.

[0027] In one embodiment of this application, the main control board 2 further includes an over-temperature protection unit and a switching unit; The over-temperature protection unit is electrically connected to the switching unit; the power supply current of the battery assembly 1 is transmitted to the host 7 through the switching unit and the pin assembly 3 in sequence; When the temperature of the over-temperature protection unit is higher than the preset temperature threshold, the over-temperature protection unit sends an over-temperature shutdown signal to the switching unit to disconnect the circuit of the switching unit.

[0028] It should be noted that when the switching unit is disconnected, the switching unit can cut off the power supply current of the battery assembly 1, thereby protecting the host 7.

[0029] The over-temperature protection unit is equipped with a temperature sensing element. When the temperature sensing element is installed on the battery assembly 1, it can acquire the temperature of the battery assembly 1 in real time. Alternatively, the temperature sensing element can be directly installed on the main control board 2 to acquire the temperature of the main control board 2 in real time. The preset temperature threshold of the over-temperature protection unit can be set to 40-70℃.

[0030] In one embodiment of this application, the main control board 2 further includes an overvoltage protection unit; The overvoltage protection unit is electrically connected to the switching unit; the overvoltage protection unit is electrically connected to the battery assembly 1; When the supply voltage of the battery assembly 1 is higher than the preset voltage threshold, the overvoltage protection unit sends an overvoltage shutdown signal to the switching unit to disconnect the circuit of the switching unit.

[0031] It should be noted that the overvoltage protection unit can be used to detect the power supply voltage of the battery assembly 1 in real time, and the preset voltage threshold of the overvoltage protection unit, i.e. the discharge cutoff voltage, can be set to 4-8V.

[0032] Reference Figure 10 In one embodiment of this application, the pin assembly 3 includes: a power supply pin 31 and a signal pin 32; The power supply pin 31 and the signal pin 32 are respectively electrically connected to the main control board 2; The encrypted electrical signal of the encryption unit is transmitted to the host 7 through the signal pin 32; the power supply current of the battery assembly 1 is transmitted to the host 7 through the main control board 2 and the power supply pin 31 in sequence.

[0033] It should be noted that the signal pin 32 can be used to transmit the encrypted electrical signal, and the power supply pin 31 can be used to transmit the power supply current. This separate transmission method avoids interference between signals. The host 7 may have a signal interface and a power supply interface that match the pin assembly 3. The main control board 2 may have a connection port 21 that matches the pin assembly 3.

[0034] In one specific embodiment of this application, the signal pin 32 and the power supply pin 31 may be arranged in a diamond shape, with pins of the same type located at the diagonals of the diamond, and the lengths of the two diagonals may be different. The power supply pin 31 may be a female pin, and the signal pin 32 may be a female pin. By setting different diagonal lengths and using different types of female pins, it can be ensured that each female pin of the power supply can be accurately connected to the host 7 during installation, preventing mis-insertion.

[0035] Reference Figure 2-3 In one embodiment of this application, it further includes: a housing 4; The battery assembly 1 and the main control board 2 are disposed inside the housing 4; the pin assembly 3 is disposed on the housing 4.

[0036] It should be noted that the battery assembly 1 and the main control board 2 are integrated through the housing 4, which facilitates the installation of the power supply. The pin assembly 3 is located on the side of the housing 4 corresponding to the host 7.

[0037] Reference Figure 2-3 In one embodiment of this application, the outer casing 4 is provided with a positioning part 41 corresponding to the host 7; the positioning part 41 is provided with a fastener 411 for connecting the host 7.

[0038] It should be noted that the positioning part 41 can be an irregularly shaped structure on the outer casing 4. As an example, when the outer casing 4 is cylindrical, the positioning part 41 can be configured as a planar structure along the axial direction of the outer casing 4. When the power supply is installed into the host 7, the latch 411 can correspond and cooperate with the locking position of the host 7, making it difficult for the power supply to detach.

[0039] Reference Figure 4-7 In one embodiment of this application, the outer shell 4 includes an upper shell 42 and a bottom cover 43; The upper shell 42 is a cylindrical structure with an opening 421 at one end; the shape of the bottom cover 43 is adapted to the opening 421.

[0040] Reference Figure 3 In one specific embodiment of this application, the bottom cover 43 has pin holes 431 corresponding to the pin assembly 3; one end of the pin assembly 3 is connected to the main control board 2, and the other end of the pin assembly 3 extends out from the pin holes 431 of the bottom cover 43. The upper shell 42 may have a plurality of heat dissipation holes 425 arranged in a circle at the end opposite to the opening 421.

[0042] It should be noted that the insulating wall 4311 can prevent a short circuit between the power supply pin 31 and the signal pin 32, thereby damaging the power supply or the host 7.

[0043] Reference Figure 4 and Figure 7 In one embodiment of this application, the inner wall of the upper shell 42 is provided with at least one limiting part 422; the limiting part 422 is provided with a positioning hole 4221 along the axial direction of the upper shell 42; The main control board 2 abuts against the limiting part 422; The main control board 2 is fixedly installed on the inner wall of the upper shell 42 through the positioning hole 4221.

[0044] It should be noted that the main control board 2 may have an opening corresponding to the positioning hole 4221, and be fixedly installed in the positioning hole 4221 by fasteners (such as screws).

[0045] Reference Figure 8-10 In one embodiment of this application, a light guide element 5 is also included; The light guide 5 includes at least one light guide post 51; the main control board 2 includes at least one light-emitting element 22; the light guide post 51 and the light-emitting element 22 are arranged in a one-to-one correspondence; The bottom cover 43 is provided with at least one light guide hole 432; the light guide hole 432 is provided to accommodate the light guide post 51.

[0046] It should be noted that the main control board 2 can convert the power information of the battery assembly 1 into light signals of the light-emitting element 22. The light from the light-emitting element 22 is displayed to the user through the light guide post 51 and the light guide hole 432. As an example, there can be four light guide posts 51, four light-emitting elements 22, and four light guide holes 432. When the power is 50%, only two of the light-emitting elements 22 emit light.

[0047] Reference Figure 6In one specific embodiment of this application, a plurality of EVA structural components 6 are also included; the EVA structural components 6 may be disposed outside the pin assembly 3 and between the pin assembly 3 and the bottom cover 43. The EVA structural components 6 may be disposed between the main control board 2 and the battery assembly 1. The EVA structural components 6 may be disposed between the light guide 5 and the light-emitting element 22 of the main control board 2.

[0049] It should be noted that users can charge the battery assembly 1 through the charging port 23.

[0053] In one specific implementation, the heating element 71 heats the tobacco in the atomizing pot 72, and the smoke generated by the tobacco in the atomizing pot 72 enters the external container 8 through the bottom of the main unit 7. The user can inhale the smoke in the container 8 through the air outlet pipe 81 of the container 8.
