Description

Technical Field

[0001] This utility model relates to the field of coffee preparation technology, and specifically to a temperature-compensated shower head device and a coffee machine. Background Technology

[0002] Americano coffee typically refers to coffee made using a drip coffee maker. Due to its simple and convenient preparation process, it is widely popular among office workers. Coffee machines used to make Americano coffee are also widely used. For example, Chinese utility model patent CN215127400U discloses a rotating shower head device and a coffee machine. The rotating shower head device includes a first cover with a spiral groove on its inner side; a second cover connected to the first cover and defining a shower head cavity; a shower head assembly disposed within the shower head cavity, comprising a shower head, a rotating bracket, and a water outlet component. The rotating bracket is fixed to the shower head, and the water outlet component is hinged to the rotating bracket, having a guide portion located within the spiral groove; and a drive mechanism connected to the shower head for driving the shower head to rotate the rotating bracket. When the rotating bracket rotates, the guide portion drives the water outlet component to spray water along a spiral trajectory. The existing rotating shower head can spray along a spiral trajectory to expand the spray range and area. When applied to a coffee machine, the coffee grounds in the entire funnel are fully wetted by the sprayed hot water, resulting in a more concentrated and aromatic coffee. However, the shower head assembly is still some distance from the hot water heating device. In addition, the temperature of the shower head body is inevitably lower than that of the hot water due to environmental factors. These factors combined result in a lower initial water temperature from the shower head, thus affecting the coffee steeping temperature.

[0003] Therefore, existing technologies still need to be improved and developed to address the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a temperature-compensated shower head device and a coffee machine.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] This invention provides a temperature-compensating shower head device, including a shower head assembly. The shower head assembly includes a shower head body with a cavity inside. The shower head body has an inlet and an outlet communicating with the cavity. The inlet is connected to a hot water supply device. A heating element for temperature compensation is connected to the shower head body. Preferably, the shower head body and the heating element are in contact. More specifically, hot water from a coffee machine flows into the cavity through the inlet and then flows out through the outlet to soak coffee grounds in the funnel. Through the above structural arrangement, the heating element can compensate for the temperature of the shower head body, thereby eliminating the influence of ambient temperature changes on the temperature of the hot water flowing through the shower head body, ultimately ensuring a stable water temperature from the shower head body.

[0007] According to the above scheme, the shower head body includes a shower head base and a shower head cover. The shower head cover is installed on the upper end of the shower head base, and the shower head base and the shower head cover are assembled to form the cavity.

[0010] According to the above scheme, the shower assembly further includes a rotary drive mechanism and a shower bracket. The shower base is horizontally rotatably mounted on the shower bracket, and the rotary drive mechanism is connected to the shower base in a transmission manner. With the above structural arrangement, the rotary drive mechanism can drive the shower base to rotate horizontally on the shower bracket, which can simulate hand-drip coffee, allowing the hot water flowing from the water outlet to evenly soak the coffee grounds in the funnel.

[0011] According to the above scheme, the rotary drive mechanism includes a drive motor and a transmission gear. Rotating teeth are formed on the outer circumference of the shower base. The drive motor is mounted on the shower bracket, and its output end is fixedly connected to the transmission gear. The transmission gear meshes with the rotating teeth of the shower base. More specifically, rotating teeth are formed on the entire outer circumference of the shower base. The drive motor is a stepper motor, and the shower base can rotate 360 ​​degrees horizontally as the stepper motor operates. Through this structural arrangement, the meshing transmission of the transmission gear and the rotating teeth allows the shower base to rotate stably on the shower bracket.

[0012] According to the above scheme, the shower head bracket includes an upper bracket and a lower bracket. The shower head cover is fixed to the lower side of the upper bracket. More specifically, the shower head cover is fixedly provided with a screw post, and the screw passes through the upper bracket and is threadedly locked to the screw post. A water inlet is fixedly provided on the upper side of the upper bracket. A water inlet column is formed on the shower head cover, and the water inlet column has a water inlet hole. The water inlet end of the water inlet column is connected to the water outlet end of the water inlet nozzle, and a second sealing ring is provided between the water inlet column and the water inlet nozzle. The water inlet end of the water inlet nozzle is connected to a hot water supply device. The shower head base is rotatably mounted on the lower bracket. The upper bracket and the lower bracket are fixedly connected. The transmission gear is rotatably placed between the upper bracket and the lower bracket. The drive motor is fixedly mounted on the upper bracket, and the output end of the drive motor passes through the upper bracket and is fixedly connected to the transmission gear. With the above structural arrangement, when the drive motor drives the shower head base to rotate, the shower head cover will not rotate accordingly.

[0013] According to the above scheme, the heating element is attached to the outer wall of the shower head cover. More specifically, the shower head cover has an annular groove formed around the water inlet column, and the heating element is an annular heating plate, which is attached to the annular groove. With the above structural arrangement, the heating element can provide compensatory heating for the shower head cover, and the rotation of the shower base does not affect the heating of the shower head cover by the heating element.

[0014] According to the above scheme, the heating element is a ceramic heating element, which is attached to the shower head body. The part of the shower head body that contacts the ceramic heating element is made of metal. Preferably, the ceramic heating element contacts the shower head cover of the shower head body for heating. With the above structural arrangement, the ceramic heating element can quickly heat the shower head body to a preset temperature.

[0015] This utility model also provides a coffee machine, including the temperature-compensated shower head device as described above.

[0016] The beneficial effects of this utility model are:

[0017] When this utility model is powered on, the heating element can compensate for the temperature of the shower head body, thereby eliminating the influence of changes in ambient temperature on the temperature of the hot water flowing through the shower head body, and ultimately ensuring a stable water temperature from the shower head body.

[0024] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0025] Example 1

[0026] like Figure 1-2As shown, this utility model provides a temperature-compensating shower head device, including a shower head assembly. The shower head assembly includes a shower head body 1, which has a cavity 112. The shower head body 1 has an inlet hole 121 and an outlet hole 111 communicating with the cavity 112. One or more outlet holes 111 can be provided as needed. The inlet hole 121 is connected to a hot water supply device. A heating element 2 for temperature compensation is contacted and connected to the shower head body 1. More specifically, as shown... Figure 3 As shown, the arrow indicates the direction of hot water flow. Hot water from the coffee machine flows into the cavity 112 from the inlet 121 and then flows out from the outlet 111 to soak the coffee grounds in the funnel. Through the above structural arrangement, the heating element 2 can compensate for the temperature of the shower head body 1, thereby eliminating the influence of ambient temperature changes on the temperature of the hot water flowing through the shower head body 1, and ultimately ensuring a stable water temperature at the shower head body 1.

[0027] Furthermore, the shower head body 1 includes a shower head base 11 and a shower head cover 12. The shower head cover 12 is installed on the upper end of the shower head base 11. The shower head base 11 and the shower head cover 12 are assembled to form the cavity 112. The water inlet hole 121 is provided on the shower head cover 12, and the water outlet hole 111 is provided at the bottom of the recessed shower head base 11. This structural arrangement facilitates the assembly of the shower head base 11 and the shower head cover 12. In this embodiment, the shower head base 11 is a cylindrical component, and the shower head cover 12 is a circular cover. The shower head base 11 has a circular mounting position, and the lower end of the shower head cover 12 is placed on the circular mounting position. A first sealing ring 5 is provided between the shower head cover 12 and the shower head base 11.

[0028] Furthermore, a drain baffle 113 is fixedly installed at the bottom of the shower head base 11, surrounding the water outlet 111, and the water inlet 121 corresponds to the interior of the drain baffle 113. Through this structural arrangement, the drain baffle 113 can collect the hot water falling from the shower head cover 12 and evenly flow it into the water outlet 111. Figure 2 , 4 and Figure 5 As shown, in this preferred embodiment, three water outlet holes 111 are provided, and the three water outlet holes 111 are arranged in a straight line from the center of the groove 112 outward. The drainage enclosure is a V-shaped structure, and the two free ends of the V-shaped structure are fixedly connected to the inner sidewall of the groove 112. The water outlet end of the water inlet hole 121 is close to the intersection of the V-shaped structure.

[0029] Furthermore, such as Figure 2 and Figure 5As shown, an exhaust column 114 is fixedly installed at the bottom of the shower base 11, and an exhaust hole 115 is provided in the exhaust column 114 to connect the inside and outside of the cavity 112. With the above structure, hot water flows into the cavity 112, generating a large amount of high-temperature steam. The high-temperature steam can be discharged from the top to the outside of the cavity 112 through the exhaust hole 115, which can effectively prevent the plastic parts in contact with the high-temperature steam from thermal deformation.

[0030] Furthermore, the shower assembly also includes a rotary drive mechanism 3 and a shower bracket 4. The shower base 11 is horizontally rotatably mounted on the shower bracket 4, and the rotary drive mechanism 3 is connected to the shower base 11 via a transmission connection. With this structural arrangement, the rotary drive mechanism 3 can drive the shower base 11 to rotate horizontally on the shower bracket 4, simulating pour-over coffee brewing, allowing the hot water flowing from the water outlet 111 to evenly soak the coffee grounds in the funnel.

[0031] Furthermore, such as Figure 4 As shown, the arrows indicate the rotation directions of each component. The rotary drive mechanism 3 includes a drive motor 31 and a transmission gear 32. The shower base 11 has rotating teeth 116 formed on its outer circumference. The drive motor 31 is mounted on the shower bracket 4, and its output end is fixedly connected to the transmission gear 32. The transmission gear 32 meshes with the rotating teeth 116 of the shower base 11 for transmission. More specifically, the entire outer circumference of the shower base 11 has rotating teeth 116. The drive motor 31 is a stepper motor, and the shower base 11 can rotate 360 ​​degrees horizontally as the stepper motor operates. Through the above structural arrangement, the meshing transmission of the transmission gear 32 and the rotating teeth 116 allows the shower base 11 to rotate stably on the shower bracket 4.

[0032] Furthermore, the shower head bracket 4 includes an upper bracket 41 and a lower bracket 42. The shower head cover 12 is fixed to the lower side of the upper bracket 41.

A water inlet 411 is fixedly provided on the upper side of the upper bracket 41. A water inlet column 123 is formed on the shower head cover 12. The water inlet column 123 is provided with the water inlet hole 121. The water inlet end of the water inlet column 123 is connected to the water outlet end of the water inlet 411. A second sealing ring 6 is provided between the water inlet column 123 and the water inlet nozzle 411. The water inlet end of the water inlet nozzle 411 is connected to the hot water supply device. The shower base 11 is rotatably mounted on the lower bracket 42. The upper bracket 41 and the lower bracket 42 are fixedly connected. The transmission gear 32 is rotatably positioned between the upper bracket 41 and the lower bracket 42. The drive motor 31 is fixedly mounted on the upper bracket 41, and the output end of the drive motor 31 passes through the upper bracket 41 and is fixedly connected to the transmission gear 32. With the above structural arrangement, when the drive motor 31 drives the shower base 11 to rotate, the shower top cover 12 will not rotate accordingly.

[0033] Furthermore, the heating element 2 is attached to the outer wall of the shower head cover 12. More specifically, the shower head cover 12 has an annular groove formed around the water inlet column 123, and the heating element 2 is an annular heating plate, which is attached to the annular groove. With the above structural arrangement, the heating element 2 can provide compensatory heating to the shower head cover 12, and the rotation of the shower base 11 does not affect the heating of the shower head cover 12 by the heating element 2.

[0034] Furthermore, the heating element 2 is a ceramic heating element, which is attached to the shower head cover 12. The shower head cover 12 is made of metal, such as aluminum alloy. With this structural arrangement, the ceramic heating element can quickly heat the shower head cover 12 to a preset temperature.
