[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Therefore, the following detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the present utility model to be protected, but merely represents the selected embodiments of the present utility model.

[0029] Referring to Figures 1 to 7 As shown, a pump head pressing head with a sound cavity structure includes an integrated circuit board 4, a speaker 3 and a housing 1. The integrated circuit board 4 and the speaker 3 are electrically connected. A chip and a control program are provided in the integrated circuit board 4, which can play music through the speaker 3 according to the program settings. An annular sound cavity wall 111 that cooperates with the speaker 3 is provided inside the housing 1. The front of the speaker 3 faces away from the sound cavity wall 111, and the periphery of the side of the speaker 3 is attached to the sound cavity wall 111, just fixing the speaker 3 and forming a closed sound cavity on the back of the speaker 3. Since the air inside the sound cavity is enclosed, the interference of air flow is reduced, thereby reducing sound distortion and improving the clarity and accuracy of the sound. The pressure changes on the front and back sides of the diaphragm of the speaker 3 do not affect each other, which helps to improve the response and clarity of the medium and high frequencies. Among them, the position of the sound cavity wall 111 can be placed at different positions inside the housing 1 according to different shapes of the housing 1. In this embodiment, the provided sound cavity wall 111 is placed at the top inside the housing 1.

[0030] Furthermore, an accommodation cavity 2 is further formed inside the housing 1, and the integrated circuit board 4 is arranged in the accommodation cavity 2, which can be used to protect the electronic components inside the pressing head from being easily splashed by water.

[0031] Further, the liquid outlet channel 123 of the pressing head is arranged at the bottom of the housing 1, making the bottom of the accommodating cavity 2 flatter, facilitating the placement of the integrated circuit board 4. The integrated circuit board 4 has a larger area and can accommodate more electronic components. Moreover, the integrated circuit board 4 can be closely attached to the housing 1, which is conducive to making the pressing head smaller in size.

[0032] Further, on the integrated circuit board 4, there are a trigger switch, a fun device, and a power source. The trigger switch can be a vibration induction trigger switch, which is triggered by the vibration of the pressing head when the pressing head is pressed; it can also be a touch trigger switch, with a sensor on the surface of the pressing head for trigger induction; it can also be an infrared induction switch, as well as a press trigger switch, which can be selected according to requirements.

[0033] The fun device refers to electronic components that can enhance the experience and fun when pressing the pump head. The fun device can be a vibration motor and / or a lamp bead, etc.

[0034] Further, the trigger switch is a press trigger switch. When the pressing head is pressed towards the pump head to a certain position, the push-button switch 41 contacts and triggers the outer shell of the pump head body 5, activating the integrated circuit board 4. There is a switch through-hole 121 on the bottom of the housing 1 that cooperates with the trigger switch. There is an infusion tube 125 on the bottom of the housing 1, and the infusion tube 125 is communicated with the liquid outlet channel 123. There is a protruding portion 124 on the outer side of the infusion tube 125. The switch through-hole 121 is arranged between the infusion tube 125 and the protruding portion 124. The height of the protruding portion 124 is higher than the switch handle, which can not only prevent water from splashing into the accommodating cavity 2 through the switch hole but also block the switch handle, improving the overall aesthetic feeling.

[0035] Further, the fun device is a lamp bead. When the pressing head is pressed down, the push-button switch 41 is triggered, and the integrated circuit board 4 controls the lamp bead to flash and the speaker 3 to play sound, enhancing the user's product experience and fun visually and auditorily.

[0036] Further, sound transmission holes 122 are arranged at the bottom of the housing 1, which enables the sound of the speaker 3 to be transmitted better, and it is not easy for water droplets on the outside to splash into the inside of the housing 1.

[0037] Further, the housing 1 is a split structure consisting of an upper housing 11 and a lower housing 12. The lower housing 12 is made of a light-transmitting material, which improves the visual perception when the lamp bead flashes. The surface of the lower housing 12 can have a matte and foggy texture, dispersing the light emitted by the lamp bead and also shielding the internal structure, improving the overall aesthetics.

[0038] Further, positioning posts 126 that cooperate with the integrated circuit board 4 are arranged at the bottom of the accommodating cavity 2, facilitating the installation and fixation of the integrated circuit board 4.

[0039] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
