In particular, the term "one" can refer to "one" in one embodiment, and can refer to "more than one" in another embodiment. Therefore, the above terms should not be a limitation on the actual number of elements of the present application.

[0037] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present application are shown in the drawings. However, the present application can be implemented in many different forms, and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0038] Reference Figure 1 and Figure 2 The embodiments of the present application disclose an inflator pump 10, which has a relatively small volume, is convenient to carry, and can be used to inflate devices such as tires that need to be inflated.

[0039] Meanwhile, in combination with Figure 3 and Figure 4The inflator 10 includes a housing 11, an air source 13, a switch module 15, and a vent pipe 17. The housing 11 is substantially hollow and rectangular box-shaped, and has a receiving groove 11a extending along an outer surface thereof. The air source 13 is disposed in the housing 11, and can include a motor 131, a crank 133 coupled to an output end of the motor 131, a piston (not shown) coupled to the crank 133, and a cylinder 135 for reciprocating movement of the piston. The vent pipe 17 is in communication with the cylinder 135. When the motor 131 is in operation, the piston is driven to reciprocate in the cylinder 135 by the crank 133. When the piston moves outward relative to the cylinder 135, air is drawn into the cylinder 135. When the piston moves inward relative to the cylinder 135, air in the cylinder 135 is compressed into the vent pipe 17. When the vent pipe 17 is connected to a device, such as a tire, that needs to be inflated, air can be filled into the tire to achieve the inflation function. In some embodiments, the inflator 10 can further include a fan 137 coupled to the output end of the motor 131. The housing 11 can be provided with a heat dissipation hole 11b. When the motor 131 is in operation, the fan 137 is driven to rotate to drive air in the housing 11 to flow through the heat dissipation hole 11b and exchange with air outside the housing 11, thereby dissipating heat from the inflator 10. In other embodiments, the air source 13 can have other forms. The air source 13 is relatively mature technology, and thus will not be described here.

[0040] The inflator 10 can further include a battery 181 and a circuit board 183 disposed in the housing 11. The battery 181 is electrically connected to the circuit board 183 and used to supply power to the air source 13, i.e., the motor 131. The battery 181 can include a battery 181 capable of repeated charging and discharging, such as a lithium battery, to improve the convenience of use of the inflator 10. The circuit board 183 can integrate control circuitry of the motor 131, etc. Further, the housing 11 can be provided with a key 191 and a display screen 193. The display screen 193 is in communication connection with the circuit board 183 and can be used to display information such as power. The display screen 193 is not limited to a digital tube or a liquid crystal screen, but can also be an OLED screen. The key 191 is used to trigger corresponding functions, such as adjusting the rotation speed of the motor 131 to adjust the inflation rate. In some embodiments, the inflator 10 can further include a light-emitting module 195 electrically connected to the circuit board 183. The light-emitting module 195 is not limited to an LED lamp. The key 191 can turn on and off the light-emitting module 195, thereby providing lighting functions, etc. In some embodiments, the inflator 10 can include a lanyard 197 connected to the housing 11. The lanyard 197 can form a threading space for threading a finger or an arm of a user. The user can thus more conveniently carry the inflator 10, thereby improving the convenience of use.

[0041] The switch module 15 is arranged in the housing 11 and electrically connected to the circuit board 183, and can be used to control the start and stop of the air source 13. The breather pipe 17 is arranged in the housing 11 and has a first state and a second state relative to the housing 11. In the first state, the breather pipe 17 is accommodated in the accommodation groove 11a to press against the switch module 15, and the air source 13 stops working, as shown in Figure 1 and Figure 2 In the second state, the end of the breather pipe 17 for externally connecting the device to be inflated is separated from the accommodation groove 11a, so as to release the pressing of the breather pipe 17 on the switch module 15, and the air source 13 works and communicates with the breather pipe 17. In other words, when the breather pipe 17 is in the first state, the breather pipe 17 is accommodated in the accommodation groove 11a extending along the circumference of the housing 11, the motor 131 of the air source 13 is powered off, and the air source 13 is in a stop state; after the user pulls out the section of the breather pipe 17 for externally connecting the device to be inflated from the accommodation groove 11a, the control circuit of the motor 131 of the air source 13 is powered on, and the user can externally connect the device to be inflated to the breather pipe 17 to inflate the device to be inflated.

[0042] This structure of triggering the switch module 15 through the breather pipe 17 can realize the start and stop control of the air source 13 through the on-off of the simple mechanical switch structure, without the need to set a complex control circuit or use a controller combined with a complex control strategy to control the start and stop of the air source 13. For example, there is no need to detect the pressing force of the breather pipe 17 on the housing 11 through a pressure sensor, and the controller responds to the detection signal to control the start and stop of the air source 13. For another example, there is no need to detect the voltage or current at the triggering position through a voltage or current detection circuit, and the controller responds to the detection signal to control the start and stop of the air source 13. The simplification of the control circuit and the controller device improves the convenience of using the inflator pump 10, and makes the inflator pump 10 have relatively high working reliability and service life, and can reduce the cost of the device, thereby reducing the cost of the inflator pump 10, so that the inflator pump 10 can be accepted by more consumers.

[0043] The above inflatable pump 10 includes a housing 11, an air source 13, a switch module 15 and a breather tube 17. The housing 11 has a receiving groove 11a extending along the outer surface thereof. The air source 13 is arranged in the housing 11. The switch module 15 is arranged in the housing 11. The breather tube 17 is arranged in the housing 11 and has a first state and a second state relative to the housing 11. In the first state, the breather tube 17 is received in the receiving groove 11a to press against the switch module 15, and the air source 13 stops working. The housing 11 can limit and protect the breather tube 17 received in the receiving groove 11a, and make the overall appearance of the inflatable pump 10 more concise. In the second state, the end of the breather tube 17 for connecting to the device to be inflated is separated from the receiving groove 11a, so as to release the breather tube 17 from pressing against the switch module 15. The air source 13 works and communicates with the breather tube 17. The user can connect the breather tube 17 to the device to be inflated outside, without the need to connect other air tubes, thereby improving the convenience of use. The arrangement of the switch module 15 realizes automatic triggering and stopping of the air source 13, further improving the convenience of use.

[0044] Further, in some embodiments, the receiving groove 11a extends along the circumference of the housing 11. In the first state, the breather tube 17 exposed outside the housing 11 is entirely embedded in the receiving groove 11a and extends along the receiving groove 11a. That is, in the first state, the breather tube 17 can be well hidden in the receiving groove 11a. Referring to Figure 5 , for example, when the user is facing the front of the inflatable pump 10, the breather tube 17 is completely blocked by the housing 11. With this structure, when the breather tube 17 is in the first state, it avoids protruding from the outer contour of the housing 11. During the process of carrying the inflatable pump 10, the flexible part of the breather tube 17 can avoid colliding or rubbing against external objects to cause accidental damage, thereby improving the service life of the breather tube 17 and further improving the service life of the inflatable pump 10. Of course, in other embodiments, the breather tube 17 can slightly protrude from the outer contour of the housing 11. The housing 11 with this structure can also protect the breather tube 17, and the appearance of the inflatable pump 10 is also more concise.

[0045] Continuing to refer to Figure 1 and Figure 2, the housing 11 can include opposite first and second surfaces 111, 112, and a peripheral side surface connecting between the first and second surfaces 111, 112, the peripheral side surface including opposite first and second peripheral side surfaces 113, 114, and opposite third and fourth peripheral side surfaces 115, 116 connecting between the first and second peripheral side surfaces 113, 114, and the receiving groove 11a extending from the first peripheral side surface 113 to the third peripheral side surface 115. In this arrangement, the receiving groove 11a at the transition between the first and second peripheral side surfaces 113, 114 can have a relatively small curvature, so that the flexible portion of the vent tube 17 can better fit the groove wall of the receiving groove 11a, preventing the vent tube 17 from being excessively bent and reducing the service life. Further, the receiving groove 11a can extend to the fourth peripheral side surface 116, and the vent tube 17 extends into the housing 11 from the side of the fourth peripheral side surface 116. After the user pulls the vent tube 17 away from the receiving groove 11a, the vent tube 17 can be bent from the fourth peripheral side surface 116 to the first peripheral side surface 113 opposite the fourth peripheral side surface 116, so that the portion of the vent tube 17 exposed outside the housing 11 has a relatively long length, facilitating user use.

[0046] Of course, in other embodiments, the receiving groove 11a in the housing 11 can have other structural forms, such as extending along an outer surface having a relatively large surface area of the housing 11, or extending from the fourth peripheral side surface 116 to other surfaces, and these variations should be considered as simple variations of the receiving groove 11a of the present application and should not be excluded from the protection scope of the present application.

[0047] Continuing to refer to Figure 3 and Figure 4 For example, in embodiments of the present application, the housing 11 can include opposite front and rear shells 117, 118 and a middle shell 119 connecting between the front and rear shells 117, 118. The front shell 117 has at least the first surface 111, the rear shell 118 has at least the second surface 112, and the middle shell 119 has part or all of the peripheral side surface. The button 191 can be provided on the front shell 117, the air source 13 and the switch module 15 can be provided on the middle shell 119, and the receiving groove 11a extends along the circumference of the middle shell 119. The battery 181 and the circuit board 183 are respectively fixed to the middle shell 119 to achieve reliable fixation in the housing 11. The front and rear shells 117, 118 can be assembled and fixed to opposite sides of the middle shell 119 in a snap-fit manner to improve the assembly convenience of the inflator pump 10 and improve the assembly efficiency of the inflator pump 10. In other embodiments, the middle shell 119 can be omitted, and the air source 13, the battery 181, the circuit board 183, etc. can be provided on the front shell 117 or the rear shell 118, and the receiving groove 11a can be located on the front shell 117 or the rear shell 118.

[0048] Referring to Figure 6 and Figure 7For example, the switch module 15 can include a carrier 151 arranged in the middle shell 119, a first conductor 153 and a second conductor 155 arranged in the carrier 151, and a contact arm 157 rotatably connected to the carrier 151. In combination with Figure 4 The middle shell 119 is provided with a through hole 11c in communication with the receiving groove 11a. In the second state, the contact arm 157 of the switch module 15 is arranged in the through hole 11c and at least partially exposed in the receiving groove 11a. In the first state, the end of the vent pipe 17 for connecting to the inflation device abuts against the contact arm 157 of the switch module 15. In other words, in this embodiment, the switch module 15 can be directly exposed in the receiving groove 11a to directly contact the switch module 15 when the vent pipe 17 is inserted to abut against the switch module 15, so as to improve the sensitivity of the switch module 15. In other embodiments, the switch module 15 can be covered by a protective member, such as a flexible silica gel sheet or a rubber sheet, to protect the switch module 15 and prevent liquid or dust from easily entering the housing 11 from the gap between the switch module 15 and the groove wall of the receiving groove 11a.

[0049] Continuing to refer to Figure 6 and Figure 7 The first conductor 153 and the second conductor 155 can respectively be in the shape of an elongated sheet, and can be made of a metal with relatively good electrical conductivity, such as copper. The first conductor 153 and the second conductor 155 are respectively electrically connected to the circuit board 183. In the first state, the vent pipe 17 abuts against the contact arm 157, and the contact arm 157 drives the first conductor 153 and the second conductor 155 to be in contact and conductive. In the second state, the first conductor 153 and the second conductor 155 are kept in a disengaged state, and the motor 131 of the air source 13 is in a powered state. The switch module 15 with this structure is relatively simple in structure, and the contact arm 157 can be made of an insulating material with relatively high insulation in the normal state, such as plastic or ceramic. Compared with the scheme in which the conductors are directly exposed in the receiving groove 11a, this structure can prevent the exposed conductors from being oxidized and worn to cause poor contact, and can also prevent the exposed conductors from being accidentally conductive to cause electric shock, thereby improving the safety in use, ensuring the reliability and service life of the inflation pump 10.

[0050] In some embodiments, in the second state, the end of the air pipe 17 for connecting to the device to be inflated is clamped in the receiving groove 11a. For example, the end of the air pipe 17 for connecting to the device to be inflated is provided with a protrusion on one of the groove walls of the receiving groove 11a, and the other groove wall is provided with a clamping groove that can be clamped with the protrusion. After the end of the air pipe 17 for connecting to the device to be inflated is pressed into the receiving groove 11a, the protrusion cooperates with the clamping groove to reliably position the air pipe 17 in the receiving groove 11a, preventing the air pipe 17 from easily coming out of the receiving groove 11a. In particular, the clamping cooperation of the end of the air pipe 17 for connecting to the device to be inflated with the groove walls of the receiving groove 11a can ensure that the air pipe 17 presses against the switch module 15, so that the air source 13 can be reliably maintained in the stopped state, avoiding the air source 13 being mistakenly started due to the air pipe 17 easily coming out of the receiving groove 11a. In other embodiments, the air pipe 17 can be reliably positioned in the receiving groove 11a by interference fit or hook or magnetic attraction, so that the air pipe 17 can be stably maintained in the second state.

[0051] In combination Figure 4 The air pipe 17 can include a pipe body 171 and a connecting head 173 connected to the pipe body 171. One end of the pipe body 171 is arranged in the housing 11 and extends to the receiving groove 11a. The connecting head 173 is connected to the other end of the pipe body 171. The hardness of the connecting head 173 is generally greater than the hardness of the pipe body 171. The pipe body 171 can have a certain flexibility to facilitate adjusting the posture of the housing 11 during inflation. The connecting head 173 has appropriate rigidity to ensure reliable fixation with the inflation interface of the device to be inflated. For example, the connecting head 173 has a part that can rotate relative to the pipe body 171. The part can have internal threads that can be screwed into the inflation interface when the part is connected to the inflation interface, thereby ensuring reliable fixation of the air pipe 17 with the inflation interface. The width of the connecting head 173 can be greater than the width of the pipe body 171. The receiving groove 11a can include a first groove 11a1 and a second groove 11a3 that are in communication with each other. The width of the second groove 11a3 is greater than the width of the first groove 11a1. The first groove 11a1 matches the shape of the pipe body 171, and the second groove 11a3 matches the shape of the connecting head 173. The first groove 11a1 and the second groove 11a3 with different widths can form a transition region with gradually decreasing width at the connection between the two grooves. The transition region can also limit the movement range of the connecting head 173, preventing the connecting head 173 from being easily pulled into the first groove 11a1 under the elastic force of the elastic pipe body 171, thereby ensuring the safety of the inflation pump 10 in use.

[0052] Of course, in other embodiments, a safety belt (not shown in the figure) can also be arranged at the second slot 11a3 of the shell 11, one end of the safety belt is fixedly connected with the shell 11, and the other end, i.e. the free end, can be buckled to or pulled away from the shell 11, i.e. the safety belt has a free end which is detachably connected with the shell 11. After the connecting head 173 of the breather pipe 17 is clamped into the second slot 11a3, the free end of the safety belt is buckled to the shell 11, the safety belt is arranged across the storage slot 11a and limits the end of the breather pipe 17 which is used to externally connect the inflating device in the storage slot 11a, so that the connecting head 173 is prevented from being easily detached from the shell 11, thereby more effectively preventing the inflating pump 10 from being mistakenly started due to the accidental situation of the connecting head 173 being detached from the shell 11 because of collision, vibration or falling, and further improving the safety of use.

[0053] The technical features of the above-described embodiments can be combined in any manner. For the sake of brevity, not all possible combinations are described, but it should be understood that any combination of the technical features is within the scope of the present disclosure.

[0054] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the present application. It should be pointed out that, for those skilled in the art, some modifications and improvements can be made without departing from the concept of the present application, and these are within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
